Description

The present invention relates to an obstacle nail maintenance device, an obstacle nail maintenance method, an obstacle nail maintenance system, and a management device capable of performing different types of maintenance on a plurality of obstacle nails provided on a game board surface of a game machine.

In a pachinko machine that plays a game by hitting a game ball into the game area, a large number of obstacle nails are driven into the game area on the game board surface. For such obstacle nails, for example, brass nails or the like are used, and they are driven onto the surface of the game board by a nail gun or the like at the time of manufacturing the game board.

When the obstacle nail is driven onto the game board surface by the nail gun in this way, an error may occur in the angle or the like of the obstacle nail with respect to the game board surface. If such an error occurs, the winning rate of the game ball will be greatly affected. Therefore, at the time of manufacturing, an obstacle nail placed on the surface of the game board is imaged, and the setting point of the obstacle nail is set based on the captured image data. Maintenance such as measuring the amount of bending or displacement from the surface and correcting the measured amount of bending or displacement may be performed. In addition, such maintenance of obstacle nails is performed not only when the game board is manufactured, but also when the pachinko game machine used in the game hall is collected, and the angle of the obstacle nail with respect to the game board surface changes due to the impact of the game ball. It may be maintained to reuse the used game board that has been used.

The guide nails 201L and 201R are arranged side by side so as to incline downward from the left and right sides toward the central ordinary winning ball device 6A, and guide the game ball toward the first starting winning opening of the ordinary winning ball device 6A. To do. A crossover 203 on which the game ball can fall is provided at each of the predetermined positions of the guide nails 201L and 201R, but the crossover 203 may not be provided.

Further, among the plurality of obstacle nails provided in the game area 10, the plurality of obstacle nails 200 provided at an upper position near the first start winning opening of the normal winning ball device 6A play a game toward the first starting winning opening. It constitutes a designated nail 204 that guides the ball. A plurality of obstacle nails 200 provided at positions above the vicinity of each general winning opening 60 constitute a designated nail 205 for guiding a game ball toward each general winning opening 60. The plurality of obstacle nails 200 provided at positions near the upper side of the passage gate 41 constitute a designated nail 206 that guides the game ball toward the passage gate 41. The plurality of obstacle nails 200 provided near the upper side of the wind turbine 61 constitute a designated nail 207 that guides the game ball toward the wind turbine 61. A plurality of obstacle nails 200 provided near the upper side of the warp passage 62 constitute a designated nail 208 for guiding the game ball toward the warp passage 62. As will be described later, these designated nails 204 to 208 are obstacle nails designated in advance from among a plurality of obstacle nails 200 provided on the game board surface 2a, and are different in content from the obstacle nails 200 other than these designated nails. It is said to be an obstacle nail that requires maintenance.

These obstacle nails 200 are made of, for example, a brass material, and as shown in FIG. 3B, have a columnar body portion 200a (also referred to as a main body portion) having a diameter of φ1 of about 1.85 mm (φ1 = about 1.85 mm). ) And a spherical head 200b (also referred to as a nail cap) having a diameter Sφ2 formed on one end side of the body portion 200a having a diameter of about 4.2 mm (Sφ2 = about 4.2 mm). The obstacle nail 200 is erected on the game board surface 2a by being driven into the hole 2d formed in advance on the game board surface 2a by a nail gun 16 described later, and in the erected state, the head from the game board surface 2a. The length L1 up to the portion 200b is about 16.8 mm (L1 = about 16.8 mm). Further, a screw groove 200c is formed on the other end side of the body portion 200a. The screw groove 200c prevents the obstacle nail 200 from falling out of the game board 2 due to the frictional force generated between the body portion 200a inserted into the hole portion 2d and the inner peripheral surface of the hole portion 2d.

Further, as shown in FIG. 9A, the hole 2d for driving the obstacle nail 200 has a predetermined angle θ1 (θ1) upward with respect to the Z axis (perpendicular line) orthogonal to the game board surface 2a. = Approximately 4 degrees) It is formed with an inclination. Therefore, since the head 200b side of the obstacle nail 200 is also erected with an inclination of about 4 degrees upward with respect to the Z axis (perpendicular line), the game ball P that collides with the obstacle nail 200 is placed on the game board 2 side as much as possible. I try to bounce back.

As shown in FIG. 3B, for example, the separation dimension L2 on the base side of the body portion 200a of the left and right obstacle nails 200 constituting the designated nail 204 is set to about 10.5 mm (L2 = about 10.5 mm). Since the separation dimension L3 on the tip end side is about 12 mm (L3 = about 12 mm), the separation dimension of the left and right body portions 200a gradually increases from the game board surface 2a toward the head 200b. Further, the diameter Sφ of the game ball P is about 11 mm (for example, Sφ = about 11 mm), and the game ball P passes between the body portions 200a of the left and right obstacle nails 200 in a state of being in contact with the game board surface 2a. Can be done.

In this embodiment, the separation dimension L2 is about 10.5 mm and the separation dimension L3 is about 12 mm of the designated nail 204, but the present invention is not limited to this, and these The dimensions can be variously changed according to the gauge configuration (so-called nail arrangement) of the game board 2. Further, the separation dimension of the other designated nails 205 to 208 can be individually set to a value different from that of the designated nail 204 (for example, 11.5 mm as described later).

Returning to FIG. 1, at the lowermost part of the game area 10, an out port 11 for taking in a game ball that has not entered any of the winning ports is provided. Speakers 8L and 8R for reproducing and outputting sound effects and the like are provided at the upper left and right positions of the game machine frame 3, and further, an effect LED 9 is provided at the peripheral portion of the game area 10.

The operation is detected by a push sensor (not shown).

Next, the circuit configuration of the pachinko gaming machine 1 will be described. On the back surface of the pachinko game machine 1, for example, a main board (not shown), an effect control board, a voice control board, an LED control board, and a relay for relaying various control signals transmitted between the main board and the effect control board are relayed. Various boards such as a board, a payout control board, an information terminal board, a launch control board, and an interface board are arranged.

The main board (not shown) is a control board on the main side, and is equipped with various circuits for controlling the progress of the game in the pachinko gaming machine 1. The main board is mainly a sub-side control board consisting of a random number setting function used in a special figure game, a function of inputting a signal from a switch or the like arranged at a predetermined position, an effect control board (not shown), and the like. It has a function to output and transmit a control command, which is an example of command information, as a control signal, and a function to output various information to the hall management computer. Further, the main board controls lighting / extinguishing of each LED (for example, segment LED) constituting the first special symbol display 4A and the second special symbol display 4B to control the lighting / extinguishing of the first special symbol and the second special symbol. Controls the variation display of a predetermined display symbol, such as controlling the variation display and controlling the variation display of the normal symbol by the ordinary symbol display 20 by controlling the lighting / extinguishing / coloring of the normal symbol display 20. It also has a function to do. Further, various circuits such as a game control microcomputer (not shown), a switch circuit (not shown), and a solenoid circuit are mounted on the main board.

A gate switch for detecting a game ball that has passed through the passing gate 41, a first starting port switch, a second starting port switch, and a wiring for transmitting detection signals from the count switch are connected to the main board. In addition, display control of the first special symbol display 4A, the second special symbol display 4B, the normal symbol display 20, the first hold display 25A, the second hold display 25B, the normal figure hold display 25C, etc. is performed. The wiring that transmits the command signal for is connected.

The control command transmitted from the main board to the effect control board via the relay board is, for example, an effect control command transmitted and received as an electric signal. The effect control command includes, for example, a variation pattern designation command indicating a variation pattern indicating a variation mode such as a variation time of the effect symbol, a type of reach effect, and the presence / absence of a pseudo-ream.

The game control microcomputer mounted on the main board is, for example, a one-chip microcomputer, which is a ROM (ReadOnlyMemory) for storing game control programs and fixed data, and a RAM for providing a work area for game control. (RandomAccessMemory102), a CPU (CentralProcessingUnit) that executes a game control program to perform control operations, a random number circuit that updates numerical data indicating a random value independently of the CPU, and I / O (Input /). Outputport) and is configured. As an example, in the game control microcomputer, a process for controlling the progress of the game in the pachinko gaming machine 1 is executed by executing a program read from the ROM by the CPU.

The effect control board (not shown) is a control board on the sub side independent of the main board, receives a control signal transmitted from the main board via the relay board, and receives the effect display device 5, speakers 8L, 8R. In addition, various circuits for controlling the production operation by the production electrical components such as various motors, solenoids, sensors, and light emitting diodes (LEDs) provided in the production LED9 and other production units are mounted.

The effect control board (not shown) includes a effect control CPU that performs control operations according to a program, a ROM that stores the effect control program, fixed data, and the like, and a RAM that provides a work area for the effect control CPU. A display control unit that executes processing for determining the control content of the display operation in the effect display device 5, a random number circuit that updates numerical data indicating a random value independently of the effect control CPU, and I / O. O is installed. As an example, in the effect control board, a process for controlling the effect operation by the effect electric component is executed by executing the effect control program read from the ROM by the effect control CPU. Further, in the ROM, in addition to the effect control program, various data tables and the like used for controlling the effect operation are stored.

Next, the progress of the game in the pachinko gaming machine 1 will be schematically described. In the pachinko gaming machine 1, the normal symbol game by the normal symbol display 20 is started based on the fact that the gaming ball has passed through the passing gate 41 provided in the gaming area 10. After starting the fluctuation of the normal symbol, if the predetermined time that becomes the normal symbol fluctuation time elapses and the normal symbol other than the normal symbol per symbol is stopped and displayed, the fluctuation display result of the normal symbol is "out of normal symbol". Become. If a specific normal symbol (design per normal symbol) is stopped and displayed, the variable display result of the normal symbol becomes "per normal symbol", and the expansion / opening control (tilt control) of the normal variable winning ball device 6B is performed to determine the predetermined value. Normal open control is performed to return to the vertical position after a lapse of time.

After the first start condition is satisfied due to the game ball winning the first start winning opening, for example, the first start condition is satisfied due to the end of the previous special figure game or the jackpot game state. , The special symbol game by the first special symbol display 4A is started. In addition, after the second start condition is satisfied due to the game ball winning the second start winning opening, for example, the second start condition is satisfied due to the end of the previous special figure game or the jackpot game state. Therefore, the special symbol game by the second special symbol display 4B is started.

In the special symbol game, after the variable display of the special symbol is started, the confirmed special symbol (special symbol display result) is derived and displayed when the variable display time elapses. At this time, if a specific special symbol (big hit symbol) is stopped and displayed, it becomes a "big hit" as a specific display result, and if a special symbol different from the big hit symbol is stopped and displayed, it becomes "missing". After the variable display result in the special figure game becomes a "big hit", the game is controlled to a big hit game state as a specific game state in which a round (also referred to as a "round game") advantageous to the player is executed a predetermined number of times.

In the big hit game state, the big winning door of the special variable winning ball device 7 is a period until a predetermined upper limit time (for example, 29 seconds or 0.1 seconds) elapses or a predetermined number (for example, 9) of winning balls. The big prize opening will be open until the occurrence of. As a result, a round is executed in which the special variable winning ball device 7 is set to the first state (open state) which is advantageous for the player.

The large winning opening door that opens the large winning opening during the execution of the round catches the game ball falling on the surface of the game board 2, and then closes the large winning opening, so that the special variable winning ball device 7 is changed to a second state (closed state) which is disadvantageous to the player, and one round is completed. The round, which is the opening cycle of the big winning opening, can be repeatedly executed until the number of executions reaches a predetermined upper limit (for example, "16").

In the effect symbol display areas 5L, 5C, and 5R of the effect display device 5, the variable display of the effect symbol is started in response to the start of the special figure game. Then, in the period from the start of the variable display of the effect symbol to the end of the variable display, the variable display state of the effect symbol may be in a predetermined reach state. The reach state is a display in which the effect symbols that have been stopped and displayed in the display area of the effect display device 5 constitute a part of the jackpot combination, and the effect symbols that have not yet been stopped and displayed continue to fluctuate. It is a state, or a display state in which all or part of the effect symbols are synchronously fluctuating while forming all or part of the jackpot combination.

As a definite special symbol in the special symbol game, among a plurality of types of jackpot combinations, a definite effect symbol that is a predetermined normal jackpot combination (also referred to as "non-probability variable jackpot combination") is stopped and displayed, and the variable display result is "non-probable variable jackpot". If it becomes, the jackpot state is controlled, and after the end, the time reduction control (time reduction control) is performed. By performing the time reduction control, the fluctuation display time (special figure fluctuation time) of the special symbol in the special figure game is shortened as compared with the normal state. In the time saving control, the so-called electric chew support is carried out in which the winning frequency of the normal symbol is increased and the winning frequency of the normal variable winning ball device 6B is increased. In the time saving control, one of the conditions that the special figure game is executed a predetermined number of times (for example, 100 times) after the end of the big hit game state and that the variable display result becomes "big hit" is satisfied first. Sometimes you just have to quit.

As a definite special symbol in the special figure game, among a plurality of types of jackpot combinations, a definite effect symbol that is a predetermined probability variation jackpot combination (also referred to as "probability variation jackpot combination") is stopped and displayed, and the variable display result is "probability variation jackpot". If it becomes a big hit, it is controlled to a big hit state, and after the end, probability fluctuation control (probability variation control) is performed together with time reduction control. By performing this probability variation control, the probability that the variation display result becomes a "big hit" in each special figure game is improved so as to be higher than in the normal state. In the probability variation control, when the condition that the fluctuation display result becomes "big hit" and the game is controlled to the big hit game state again after the end of the big hit game state is satisfied, a predetermined number of times (for example, 100, which is the same as the time reduction number) after the end of the big hit game state When the special figure game of (times) is executed, it is decided that "there is a probability change fall" to end the probability change control by the probability change fall lottery that is executed every time the special figure game is started after the jackpot game state ends. When, etc., it should end.

When the time reduction control is performed, the fluctuation time of the normal symbol (normal symbol fluctuation time) in the normal diagram game is made shorter than that in the normal state, and the variation display result of the normal symbol in each normal diagram game is "normal diagram". Control to improve the probability of "hit" compared to the normal state, tilt control time to control the tilt of the movable wing piece in the normal variable winning ball device 6B based on the fact that the variation display result is "hit" It is possible to make it easier for the game ball to pass (enter) the second start winning opening, such as control to make it longer than in the normal state and control to increase the number of tilts than in the normal state, and the second start condition can be satisfied. Controls (electric chew support control, high open control) that are advantageous to the player by enhancing the performance are performed. This makes it easier to establish the second start condition for executing the special figure game using the second special figure, and the special figure game can be executed frequently, so that the variable display result is "big hit" next. The time until becomes is shortened.

Next, the operation (action) of the pachinko gaming machine 1 in this embodiment will be described. In the main board (not shown), when the power supply from the predetermined power supply board is started, the game control microcomputer (not shown) is started, and the CPU (not shown) performs the game control main process.

In the special symbol process processing, the CPU first determines whether or not there is a first start prize or a second start prize, and if there is a prize, it is for determining the special symbol display result, for determining the jackpot type, and the variation pattern. A start winning process is executed in which random values for determination and the like are extracted and stored (stored) at the highest level of empty entries in the first special figure holding storage device and the second special figure holding storage device.

Further, the CPU determines whether or not to start the special figure game based on the presence or absence of the hold data stored in the first special figure hold storage device and the second special figure hold storage device, and the special figure display result. Based on the numerical data indicating the random value for judgment, it is decided (predetermined) whether or not the variation display result of the special symbol or the effect symbol is a "big hit" before the variation display result is derived and displayed. Executes normal symbol processing. That is, when starting the variable display of the special figure game, the CPU determines whether or not to derive and display the jackpot display result as the display result of the variable display based on the random number value stored when the start winning prize occurs. Execute the process of determining (lottery).

Next, a variation pattern setting process for determining the variation pattern to one of a plurality of types, a special symbol variation process for setting to change the special symbol and a process for measuring the elapsed time from the start of the variation of the special symbol, Stop the fluctuation of the special symbol and confirm it. Perform the special symbol stop processing to set the stop display (derivation) of the special symbol. When the variable display result is "big hit", the big hit opening pre-processing, the big hit opening processing, the big hit opening post-processing, and the big hit end processing are performed to open and close the big winning opening in the big hit game state.

Next, the operation of the effect control board (not shown) will be described. First, the effect control CPU starts executing the main process when the power is turned on. When a timer interrupt occurs in the main process, command analysis process, effect control process process, and effect random number update process are executed.

In the effect control process process, the hold storage display in the first hold storage display area 5D and the second hold storage display area 5U of the effect display device 5 is updated to the display according to the storage contents of the hold storage buffer. To execute. Next, according to the value of the effect control process flag, the variation pattern specification command reception waiting process for confirming whether or not the variation pattern specification command is received from the game control microcomputer is controlled so that the effect symbol variation is started. Control of the switching timing of each fluctuation state (fluctuation speed) that composes the fluctuation pattern according to the process data set in the production symbol fluctuation start processing and the production symbol fluctuation start processing, and monitor the end of the fluctuation time. Display control of the effect display device 5, sound output from the speakers 8L and 8R, light emission of the effect LED 9 and drive control of the effect unit (not shown), etc. During the effect symbol change processing, the effect symbol change is stopped and the display result is displayed. Controls to derive and display (stop symbol) The effect symbol fluctuation stop processing is performed.

In the jackpot display process, after the end of the fluctuation time, the effect display device 5 is controlled to display a screen for notifying the occurrence of the jackpot. In the processing during the big hit game, control is performed during the big hit game. In the jackpot end effect processing, the effect display device 5 performs display control to notify the player that the jackpot game state has ended.

Code, serial number 15c indicating the serial number (unique ID) of the game board 2, production company classification code, bar code information 15f for making data with a conventionally used bar code available, game board 2 Print various codes including a cell number 15e that can specify the type of cell sheet attached to the back surface of the data, and an individual two-dimensional code 15a that symbolizes a print date code indicating the date and time printed on the sticker 15 described later. Then, the work of attaching the seal 15 is performed (step S2). In this embodiment, the information symbolized by the two-dimensional code 15a includes a nail gun code indicating a nail gun 16 for driving an obstacle nail 200 on the game board 2 to which the seal 15 is attached. However, if it is determined in advance before the obstacle nail 200 is put into the line on the game board 2, it may be a two-dimensional code 15a including these nail gun codes, and it is symbolized by these two-dimensional codes 15a. The type of information to be used may be appropriately determined.

In the production line 12 of this embodiment, different types of game boards 2 can be manufactured, and the nail arrangement and the maintenance contents of the obstacle nails 200 differ depending on the type of the game board 2. Therefore, the various devices provided on the production line 12 read the two-dimensional code 15a printed on the sticker 15 with a reading camera (not shown), and transmit the read serial number and the device number to the management computer 500. .. The management computer 500 that has received the serial number extracts maintenance data corresponding to the serial number, that is, maintenance data corresponding to the game board 2 specified from the serial number from the storage device 505, and is specified from the received device number. The extracted maintenance data is transmitted to the device of the transmission source. Then, in various devices, nailing and maintenance are performed based on the maintenance data received from the management computer 500. In the production line 12, in the nailing (process S3), the first maintenance (process S5), the second maintenance (process S7), etc., which will be described later, the nailing machine 16 is used for nailing and the obstacle nail maintenance device 300 is used for maintenance. Defects may occur.

In the production line 12, the transport device 13 on the supply side and the transport device 13 on the discharge side are arranged in parallel, and each nail gun 16 and each obstacle nail maintenance device 300 are supplied by the robot arm device described above. The specification is such that the game board 2 is arbitrarily taken out from the transport device 13 on the side and placed or maintained, and then the placed or maintained game board 2 is returned to the transport device 13 on the discharge side. Since it has not been determined in advance whether nail maintenance or nailing will be performed by the device of No. 1, the device involved in the manufacture of each game board 2 can be specified by storing the maintenance history of each game board 2 in the storage device 505. I am trying to do it. As this maintenance history information is accumulated, it becomes possible to identify which of the various devices has a large number of maintenance defects. Therefore, maintenance work for a plurality of devices installed on the production line 12 can be performed. It is said that it can be done easily.

Further, by storing the maintenance history of each game board 2 in the storage device 505, when a defect of an obstacle nail is found at the final stage of the manufacturing process or after delivery, the maintenance history of the game board 2 is referred to and the game board is concerned. Since it is possible to identify the device involved in the manufacture of 2, that is, the device that may have a defect, the device that may have a defect does not cause maintenance of a new game board 2. As described above, it is possible to take measures at an early stage, such as immediately stopping the drive of the device and performing maintenance work.

Further, in step S2, the sticker 15 on which the two-dimensional code 15a is printed is placed on the lower part of the board surface plate 2A (for example, a position where the sticker 15 is not exposed from the outside when mounted on the pachinko gaming machine 1. The work of attaching to is performed (see FIG. 2). Further, the seal 15 is provided with a reading camera provided at a predetermined position of the production line 12 (for example, each nail gun 16, each obstacle nail maintenance device 300, a first nail inspection device 17A, a second nail inspection device 17B). In addition to the two-dimensional code 15a read by, the print date 15g, model code 15b, serial number 15c, gauge number 15d, cell number 15e, bar code information 15f, etc. are alphabetically displayed so that the operator can visually confirm. It is indicated by numbers, symbols, etc. (see FIG. 17).

In this embodiment, since the order in which the game board 2 is conveyed to the first two-dimensional code marking device 14a through the step S1 is not changed in the transfer, the game is performed in the first two-dimensional code marking device 14a. Although it is not necessary to specify the type of the board 2, the present invention is not limited to this, and a one-dimensional code or the like capable of specifying the serial number is attached to the game board 2 in advance in step S1. The type of the game board 2 may be specified by the first two-dimensional code marking device 14a based on the serial number specified from the one-dimensional code.

Further, in the present embodiment, the sticker 15 on which the two-dimensional code 15a is printed is attached to the board surface plate 2A so that the two-dimensional code 15a can be read by a reading camera (reading device). The invention is not limited to this, and it is very good that the information stored in the IC chip can be read by a predetermined reader by attaching a sticker containing the IC chip in which the above-mentioned various information is stored.

After the marking work of the two-dimensional code 15a on the board surface plate 2A is completed, a nail gun 16 is used to drive a plurality of obstacle nails 200 into the prepared holes processed in step S1 (step S3). When the nailing machine 16 finishes driving the obstacle nail 200, the nailing machine 16 displays the device number of the nailing machine 16, the reading data of the two-dimensional code 15a read by the reading camera, the temperature and humidity at the time of the work, and the like. The information is transmitted to the management computer 500 as nailing work completion data. Then, the obstacle nail 200 driven into the game board surface 2a by the first nail inspection device 17A is photographed by a plurality of cameras 44 described later (see FIG. 16), and each obstacle nail 200 is photographed based on the photographed image data. A nail image inspection is performed to inspect the inclination (arrangement position coordinates of the head 200b, etc.) in the Z-axis direction orthogonal to the game board surface 2a, the presence or absence of an obstacle nail 200, nail bending, rust, discoloration, and the like (step S4). When the inspection is completed, the first nail inspection device 17A transmits the primary inspection result data to the management computer 500 together with the device number of the first nail inspection device 17A and the reading data of the two-dimensional code 15a of the game board 2.

The management computer 500 (CPU502) that has received the primary inspection result data tilts each of the obstacle nails 200 upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a based on the received primary inspection result data. Whether or not it is present is determined from the misalignment direction and the misalignment amount in the XY axis direction with respect to the set position of the head 200b of each obstacle nail 200 specified from the gauge data corresponding to the game board 2. The set position (coordinate position) of the head 200b of each obstacle nail 200 is a position where the head 200b is arranged when the obstacle nail 200 is accurately driven into the prepared hole, and corresponds to the type of the game board 2. It is stored as gauge data in the storage device 505 of the management computer 500.

Further, for each set position, an allowable range (accuracy) is set in consideration of an error in the XY axis direction, and when the head 200b is arranged outside this allowable range, it is determined to be abnormal (defective). At the same time, the direction of deviation from the set position and the amount of deviation are specified. As will be described later, this permissible range can be set to a desired value for each obstacle nail 200 (see FIGS. 18 and 19).

The management computer 500 (CPU502), which has received the primary inspection result data, has a deviation in the XY-axis direction with respect to the set position of the head 200b due to the inspection in step S4 among the obstacle nails 200 driven in step S3. For the obstacle nail 200 determined to be present, the first maintenance data for arranging the head 200b of the obstacle nail 200 within the permissible range of the set position is created, and the first maintenance data is received. It is stored in association with the serial number 15c in the read data of the two-dimensional code 15a included in the inspection result data. The first maintenance data is read data including the serial number 15c from the obstacle nail maintenance device 300 from which the game board 2 to which the sticker of the two-dimensional code 15a of the serial number 15c is attached is taken out from the transport device 13. Is transmitted (replied) to the obstacle nail maintenance device 300, and maintenance based on the first maintenance data is instructed.

The obstacle nail maintenance device 300 performs the first maintenance for the obstacle nail 200 in which an abnormality is detected in the process S4 based on the first maintenance data received from the management computer 500 (process S5). When the first maintenance is completed, the management computer 500 receives the first maintenance completion data including the reading data of the two-dimensional code 15a and the temperature / humidity information at the time of executing the first maintenance, together with the device number of the obstacle nail maintenance device 300. Information related to the first maintenance such as the device number and temperature / humidity information of the obstacle nail maintenance device 300 that executed the first maintenance is transmitted to the management computer 500. ..

Then, with respect to the obstacle nails 200 after the first maintenance, whether or not each obstacle nail 200 is tilted upward by about 4 degrees with respect to the Z-axis direction orthogonal to the game board surface 2a is determined with respect to the set position of the head 200b. The first inspection is performed based on the misalignment direction in the XY axis direction and the amount of misalignment, and the inspection result of the first inspection is the device number of the obstacle nail maintenance device 300 and the reading of the two-dimensional code 15a. Together with the data, it is transmitted to the management computer 500 as the first inspection completion data. In this embodiment, these first inspections are performed by the obstacle nail maintenance device 300 using the inspection tool 600 as in the second inspection described later, but the present invention is limited thereto. Instead, these first inspections may be performed by the second nail inspection device 17B.

In this embodiment, the first maintenance completion data and the first inspection completion data are individually transmitted to the management computer 500, but the present invention is not limited to this, and these are subjected to the first inspection. You may send them all at once when the above is completed.

The first maintenance (S5) and the first inspection (S6) are repeated until all the heads 200b of the obstacle nail 200 after the first maintenance are arranged within the allowable range of the set position (S6 +). However, since the obstacle nails 200 placed within the permissible range by the first maintenance again are excluded from the target of the first maintenance again, the obstacle nails to be maintained as the first maintenance is repeatedly executed. The number of 200 will gradually decrease.

At the time of these repeated redevelopments, the first maintenance data is created again in the management computer 500 based on the inspection result of the first inspection, and the nail maintenance is executed based on the created first maintenance data. To. The first maintenance completion data is also transmitted to the management computer 500 every time the first maintenance is repeated.

It should be noted that the maintenance contents based on the first maintenance data created by these management computers 500 will be sequentially different maintenance contents according to the number of times (inspection NG times) determined to be not within the permissible range in the first inspection. It has been set. Specifically, as shown in FIG. 6, when the number of inspections is NG for the first time, in principle, the maintenance amount (deformation amount) of the obstacle nail 200 determined to be inspection NG is determined to be the inspection NG. The maintenance content is changed to a maintenance amount (deformation amount) different from the maintenance amount (deformation amount) in the first maintenance before the operation. In addition, when the number of inspection NGs is the second time, in principle, the maintenance content is changed to a tool different from the tool used for the maintenance of the obstacle nail 200 determined to be inspection NG. In addition, when the number of inspection NGs is the third time, in principle, the maintenance content is changed to the obstacle nail maintenance device 300 different from the obstacle nail maintenance device 300 used for the maintenance of the obstacle nail 200 determined to be inspection NG. To. That is, when the first maintenance in which the tool corresponding to the second inspection NG number is changed is executed, the obstacle nail maintenance device 300 that has executed the first maintenance has the obstacle nail 200 that has executed the first maintenance. The game board 2 having the above is thrown into the transport device 13 by the robot arm device, and the first maintenance is performed by another obstacle nail maintenance device 300 which takes out the thrown game board 2 from the transport device 13 by the robot arm device. Will be executed. Then, when the inspection is NG in the first inspection after the first maintenance is executed by the other obstacle nail maintenance device 300, the game board 2 is set as a discharge target from the production line. To. Specifically, the obstacle nail maintenance device 300 determined to be inspected NG is discharged to the outside of the production line by the robot arm device.

That is, in the management computer 500 of this embodiment, when there is an obstacle nail 200 of inspection NG in the first inspection, as shown in FIG. 6, the first maintenance from the first to the third maintenance is the maintenance content. Sends the first maintenance data for performing different redevelopment.

In this embodiment, in the first maintenance, maintenance is performed only for the obstacle nail 200 in which an abnormality is detected in the nail image inspection in step S4, but the present invention is limited to this. Instead, the first maintenance may be performed on all the obstacle nails 200 regardless of the presence or absence of abnormality.

When it is determined in the first inspection that there is no obstacle nail 200 for inspection NG (N in S6 +), the game board 2 is returned to the transfer device 13 by the robot arm device. Then, the game board 2 returned to the transfer device 13 is taken out from the transfer device 13 by the robot arm device of the other obstacle nail maintenance device 300, and is designated in advance according to the type of the game board 2 among the plurality of obstacle nails. A second maintenance is carried out for arranging the head 200b of the obstacle nail 200 within the permissible range of the designated position for the obstacle nail 200 (for example, designated nails 204 to 208). That is, with respect to the obstacle nail maintenance device 300 that took out the game board 2 that has completed the first inspection from the transfer device 13, the management computer 500 uses the obstacle nails that are designated in advance according to the type of the game board 2 among the plurality of obstacle nails. Targeting 200 (for example, designated nails 204 to 208), the second maintenance data for arranging the head 200b of the obstacle nail 200 within the allowable range of the designated position is transmitted to instruct the execution of the second maintenance. To do. The obstacle nail maintenance device 300 that has received the second maintenance data performs the second maintenance for the designated nails 204 to 208 based on the received second maintenance data (step S7).

As described above, in this embodiment, by performing the second maintenance in the obstacle nail maintenance device 300 different from the obstacle nail maintenance device 300 in which the first maintenance is performed, the bias of the maintenance accuracy due to the difference in the obstacle nail maintenance device 300 is made. Although it is possible to prevent this, the present invention is not limited to this, and the same obstacle nail maintenance device 300 may perform the first maintenance and the second maintenance.

Specifically, in the second maintenance, for example, the distance between the pair of obstacle nails 200 in each of the designated nails 204 to 208 is gradually widened from the base side to the head 200b side so as to have a desired size (FIG. 3 (B)). (See FIG. 9B), the head 200b is arranged at a designated position different from the set position. In addition, it also includes maintenance for changing the inclination angle, inclination direction, arrangement mode of each obstacle nail 200 with other obstacle nails 200, etc., regardless of whether or not it was maintained in the first maintenance in step S5. Will be done.

Further, for each designated position, an allowable range (accuracy) is set in consideration of an error in the XY axis direction, and when the head 200b is arranged outside the allowable range, it is determined as abnormal and designated. The direction of deviation from the position and the amount of deviation are specified. As will be described later, this permissible range can be set to a desired value for each obstacle nail 200 (see FIGS. 18 and 19).

These designated nails 204 to 208 are related to the probability of the game ball entering each winning opening or passing gate 41 related to the addition of the game value, among the plurality of obstacle nails 200 driven into the game board surface 2a. This is an obstacle nail that is likely to affect the base value of the pachinko machine 1 due to slight errors or deviations. Further, the inclination angle, the inclination direction, and the arrangement mode of each obstacle nail 200 with the other obstacle nail 200 change according to the type of the game board 2. As will be described later, this designated nail can specify a desired obstacle nail 200 for each game board 2 (see FIG. 20).

As described above, the first maintenance targets the obstacle nail 200 in which the abnormality is detected in the process S4 among the plurality of obstacle nails 200 driven into the game board surface 2a in the process S3, and the obstacle nail 200 having the abnormality is targeted. The second maintenance targets a predetermined designated obstacle nail (for example, designated nails 204 to 208), while the work of arranging the head 200b of the head 200b within the allowable range of the set position is included. Includes the work of arranging the head 200b of the obstacle nail 200 within the allowable range of the designated position. That is, in the second maintenance and the process S7 in which the second maintenance is performed, maintenance having a content different from that in the process S5 in which the first maintenance and the first maintenance are performed is performed.

Further, the second maintenance is a maintenance that cannot be uniformly or is difficult in the nailing process by the nail gun 16, and requires delicate work with higher accuracy than the first maintenance, so other obstacle nails. By performing the maintenance work separately from the first maintenance targeting the 200, the maintenance work of the obstacle nail 200 can be efficiently performed. Further, in the game board 2 of the type that does not require the second maintenance for the designated nails 204 to 208, the second maintenance in the step S7 may be omitted.

Then, after performing the second maintenance for the obstacle nails 200 of the designated nails 204 to 208, the final inspection (process S9) by the second nail inspection device 17B is performed by using the inspection tool 600 described later. By the method, a second inspection is performed to determine whether or not the obstacle nails 200 of the designated nails 204 to 208 are arranged within the allowable range of the designated position. The second inspection and the second maintenance are repeated until the head 200b of the obstacle nail 200 after the second maintenance is arranged within the allowable range of the designated position (S8 +). However, since the obstacle nails 200 placed within the permissible range by the second maintenance again are excluded from the target of the second maintenance again, the obstacle nails to be maintained as the second maintenance is repeatedly executed. The number of 200 will gradually decrease.

In the present embodiment, these second inspections are performed by the obstacle nail maintenance device 300 using the inspection tool 600 as in the first inspection, but the present invention is not limited thereto. , These second inspections may be performed by the second nail inspection device 17B.

At the time of these repeated maintenance, the second maintenance data is created again in the management computer 500 based on the inspection result of the second inspection, and the nail maintenance is executed based on the created second maintenance data. .. The second maintenance completion data is also transmitted to the management computer 500 every time the second maintenance is repeated.

It should be noted that the maintenance contents based on the second maintenance data created by these management computers 500 will be sequentially different maintenance contents according to the number of times (inspection NG times) determined to be not within the permissible range in the second inspection. It has been set. That is, maintenance with different contents is executed according to the same rules as the first maintenance described above. Specifically, as shown in FIG. 6, when the number of inspection NGs is the first time, in principle, the maintenance amount (deformation amount) is changed, and when the number of inspections NG is the second time, the maintenance content is changed. As a general rule, the maintenance content is changed to a different tool, and when the number of inspection NGs is the third time, in principle, the maintenance content is changed to a different obstacle nail maintenance device 300, and when the inspection NG number is the fourth time. Is set as a discharge target and is discharged outside the production line.

That is, in the management computer 500 of this embodiment, when there is an obstacle nail 200 of inspection NG in the second inspection, as shown in FIG. 6, the first maintenance from the first to the third maintenance is the maintenance content. Sends second maintenance data to perform different redevelopment.

As described above, when the second maintenance and the second inspection for the designated nails 204 to 208 are completed, the obstacle nail maintenance device 300 that has performed the second maintenance is attached to the reading camera together with the device number. Manages the second maintenance completion data including the read data of the two-dimensional code 15a read, the temperature and humidity information at the time of execution of the second maintenance and the second inspection, and the inspection result information (second inspection result information) of the second inspection. By transmitting to the computer 500, the second maintenance and the second inspection have been completed on the management computer 500, and the device number, temperature and humidity information, and the inspection of the second inspection of the obstacle nail maintenance device 300 that executed the second maintenance. Information on the second maintenance such as result information is transmitted.

When it is determined in the second inspection that there is no obstacle nail 200 of the inspection NG (N in S8 +), the game board 2 in which the second inspection is performed is moved to the transport device 13 on the discharge side by the robot arm device. It is thrown in and conveyed to the second nail inspection device 17B, and the second nail inspection device 17B performs a final inspection of all the obstacle nails 200 to see if the head 200b of each obstacle nail 200 is in the set position. (Step S9). In this embodiment, the positions of all the obstacle nails 200 on the game board 2 are inspected in step S9, but the present invention is not limited to this, and only the designated nails 204 to 208 are used. You may want to inspect. Further, the game board 2 in which an abnormality is detected in step S9 is taken out from the production line 12 and re-maintained by an obstacle nail maintenance device 300 or the like different from the production line 12, and the re-maintenance is completed. The second maintenance completion data is transmitted from the obstacle nail maintenance device 300 that has undergone the redevelopment to the management computer 500.

If there is no abnormality in the final inspection of the second nail inspection device 17B, the guide rail 2b and the wind turbine 61 are attached using the pilot holes formed in the game board surface 2a (step S10). Then, after attaching other gaming members such as the center decorative frame 51 and various winning devices, the pachinko gaming machine 1 is assembled to the gaming machine frame 3 (process S11). Finally, the completed pachinko gaming machine 1 is packed and shipped (process S12).

In the following, for convenience of explanation, the obstacle nail maintenance device 300 will be described not with reference to the vertical / horizontal direction of the pachinko gaming machine 1 but with reference to the vertical / horizontal direction of FIGS. 7 and 8. Further, it is assumed that the game board 2 is horizontally placed with the upper side in the state of being assembled to the pachinko game machine 1 facing the front side in FIGS. 7 and 8.

As shown in FIGS. 7 and 8, the obstacle nail maintenance device 300 in the present embodiment includes a maintenance arm 301 for maintaining the obstacle nail 200 and a game board 2 on which the obstacle nail 200 to be maintained is placed. It is mainly composed of a table 302 placed horizontally. As described above, the obstacle nail maintenance device 300 includes a robot arm device and the like for taking out and loading the game board 2 from the transfer device 13, but in the following description, these robot arm devices and the like are used. The omitted nail straightening device will be described as an obstacle nail maintenance device 300.

The maintenance arm 301 includes a base 310 mounted on the floor surface, a turntable 312 rotatably provided about a rotation shaft T1 oriented in the direction perpendicular to the base 310, and a turntable 312. A first arm 313 that is rotatably provided about a rotation shaft T2 that faces the horizontal direction and a rotation shaft T3 that is rotatably provided at the tip of the first arm 313 that faces the horizontal direction. A second arm 314, a third arm 315 rotatably provided at the front end of the second arm 314 via a rotation shaft T4 that faces the horizontal direction, and a rotation that faces the tip of the third arm 315 in the horizontal direction. A fourth arm 316 rotatably provided about the moving shaft T5, a head 317 provided at the tip of the fourth arm 316 and to which a maintenance tool 400 described later can be attached, and a maintenance tool attached to the head 317. Mainly has 400 and.

In this way, the maintenance arm 301 composed of the articulated arms is connected to the management computer 500 described above, and is built into the base 310 and each arm based on a command from the management computer 500 (CPU502). By driving a drive source (not shown) such as a motor, the maintenance tool 400 is moved in the horizontal direction (front-back / left-right direction, XY-axis direction) along the game board surface 2a and in the vertical direction (up / down) orthogonal to the game board surface 2a. It can be moved in the direction (direction, Z-axis direction), or tilted with respect to the Z-axis.

In the present embodiment, the maintenance arm 301, which is an example of the operating means for operating the maintenance tool 400, is composed of an articulated arm, but the present invention is not limited to this, and is for maintenance. A manipulator other than the articulated arm may be used as long as the tool 400 can be moved in the XY-axis direction, the Z-axis direction, or tilted with respect to the Z-axis.

On the upper surface of the table 302, guide pins that can be inserted into the guide holes formed at predetermined positions of the game board 2 (in this embodiment, four places around the game board 2) are erected. The game board 2 is placed on the table 302 by a robot arm device (not shown) so that the guide pin is inserted into the guide hole. A slide clamp 330 is provided on one side edge of the table 302 so that the table 302 can be moved in the left-right direction and the game board 2 placed on the table 302 can be pushed to the left. As shown in FIG. 8, the slide clamp 330 pushes the game board 2 placed on the table 302 to the left, so that the guide pin inserted into the guide hole hits the right side surface of the guide hole. By coming into contact with each other, it is possible to suppress the occurrence of misalignment due to the gap (play) between the guide hole and the guide pin.

Further, as shown in FIG. 8, the upper surface of the table 302 is provided with a mounting portion for mounting the detection pin G for detecting the positional deviation at the front right corner position. The detection pin G mounted on the mounting portion has a constricted portion in the center and has a structure that can be easily broken when the upper portion is moved back and forth and left and right, and has a slightly larger diameter than the detection pin G. The maintenance tool 400 is replaced with the misalignment confirmation tool 400'having a large insertion hole, and the misalignment confirmation tool 400' is vertically aligned with the position of the mounting portion where the detection pin G is mounted by the maintenance arm 301. If the position shift does not occur, the detection pin G will not break, but if the position shift occurs, the detection pin G will break and the position shift will occur. It is easy to recognize that you are there. If there is a misalignment, a predetermined correction process is performed to correct the misalignment.

Further, as shown in FIG. 8, a pair of elevating clamps 320 provided so as to be movable in the front-rear direction by the slide mechanism 340 are provided on both upper side edges of the table 302, and on the upper surface of the table 302, With the game board surface 2a facing upward so that the obstacle nail 200 faces upward, the game board 2 is held between the table 302 by pressing the game board 2 from above the obstacle nail 200, and the game board 2 is held on the table 302. , Can be fixed.

As shown in FIG. 8, the elevating clamp 320 of this embodiment is formed of a substantially U-shaped transparent resin plate having a gap formed in the central portion, and the obstacle nail 200 to be maintained is the obstacle nail 200. The elevating clamp 320 moves sequentially so as to be located directly under the gap, and by pressing the nail close to the obstacle nail 200 to be maintained by the elevating clamp 320 to fix the game board 2, the position shift in maintenance occurs. In addition to preventing this, even if the obstacle nails 200 to be maintained are pressed, the maintenance status of the obstacle nails 200 to be maintained can be visually recognized through the transparent elevating clamp 320.

As shown in FIG. 7, the maintenance tool 400 is made of a rod-shaped portion 401 made of a metal rod-shaped member having a diameter of about 6 mm (φ10 = about 6 mm) and a metal material attached to the lower end side of the rod-shaped portion 401. It is mainly composed of a holding portion 403 and the upper end of the rod-shaped portion 401 can be exchangeably attached to the head 317, and there are a plurality of types having different shapes of the holding portion 403 (FIG. 12). (See), as shown in FIG. 8, a predetermined number is provided in advance so as to be replaceable around the base 310.

In the obstacle nail maintenance device 300 of this embodiment, the clamp control pattern A shown in FIG. 10A and the clamp control pattern B shown in FIG. 10B are used to hold and fix the game board 2 by the elevating clamp 320. And are set, and the control unit 300'controls the position and pressing pressure of the elevating clamp 320 based on the set clamp control pattern.

In the clamp control pattern A, as shown in FIG. 10A, the obstacle nail 200 to be maintained is positioned in a substantially U-shaped gap of one elevating clamp 320, and the position of the other elevating clamp 320 is set back and forth. This is a clamp control pattern that is arranged symmetrically with respect to the center position in the direction and controls the game board 2 to be pressed, held, and fixed with a lower pressure (smaller force) than the clamp control pattern B.

As shown in FIG. 10B, the clamp control pattern B has a higher pressure (larger) than that of the clamp control pattern A on the game board 2 in a state where both elevating clamps 320 are arranged at the center positions in the front-rear direction. It is a clamp control pattern that controls to hold and fix by pressing with force). In the clamp control pattern B, when the elevating clamp 320 is arranged at the center position in the front-rear direction, if the obstacle nail 200 to be maintained is covered with the elevating clamp 320, the obstacle nail 200 to be maintained is covered. Moves the position of the elevating clamp 320 to a position where the elevating clamp 320 is not covered by the elevating clamp 320 to hold and fix the game board 2.

In this embodiment, each of these clamp control patterns is selected according to the maintenance content, as shown in FIG.

Specifically, when the obstacle nail 200 to be maintained is the designated nail 204 to 208, the clamp control pattern B is selected (see FIG. 10B), and the obstacle nail 200 to be maintained is the designated nail 204 to 208. When the obstacle nail 200 is other than 208, the clamp control pattern A is selected (see FIG. 10 (A)).

Further, when the tool type in maintenance is the maintenance tool 400 of the tool type A used for servicing only one obstacle nail 200 having a tubular shape, the clamp control pattern A is selected and a plurality of clamp control patterns A are selected. In the case of the maintenance tool 400 of the tool types B and C used for simultaneously servicing the obstacle nail 200, the clamp control pattern B is selected.

Further, when the fluctuation amount (maintenance amount) in maintenance is equal to or more than a preset predetermined threshold value, the clamp control pattern B is selected, and when the fluctuation amount (maintenance amount) is less than the threshold value, clamp control is performed. Pattern A is selected.

In principle, the relationship between these maintenance contents and the clamp control pattern is given priority to the clamp control pattern B. That is, when the maintenance content includes the maintenance content corresponding to the clamp control pattern B, for example, even if the maintenance content is other than the designated nails 204 to 208 and the maintenance content is based on the tool type A, the fluctuation amount When the (maintenance amount) is equal to or greater than the threshold value, the clamp control pattern B is selected.

As described above, in this embodiment, there are differences in the types of obstacle nails 200 to be maintained, differences in the types of maintenance tools 400 used for maintenance, and differences in the amount of fluctuation (maintenance amount) in maintenance. Since different clamp controls are performed according to the above, the game board 2 can be preferably held, and a plurality of types of maintenance having different maintenance contents can be appropriately performed.

Next, the maintenance tool 400 used for maintenance in the obstacle nail maintenance device 300 will be described. As shown in FIG. 12, there are a plurality of types of maintenance tools 400 having different shapes of the holding portions 403.

Specifically, the maintenance tool 400 is roughly classified into three types according to the number of obstacle nails 200 to be maintained at the same time. Tool type A is a maintenance tool 400 used for servicing only one obstacle nail 200, and tool type B is a maintenance tool used for servicing two obstacle nails 200 at the same time. It is 400, and the tool type C is a maintenance tool 400 used for servicing three obstacle nails 200 at the same time.

Further, as illustrated in A-1 to A-4 of FIG. 12, there are a plurality of types of maintenance tools 400 of the tool type A depending on the shape of the tip portion, the size of the opening, and the like. These tool types A are mainly used for maintenance of guide nails 201L and 201R called continuous nails.

Further, the maintenance tool 400 of the tool type B is also used as illustrated in B-1 to B-4 of FIG.
There are a plurality of types depending on the width and shape of the groove through which the obstacle nail 200 formed in the holding portion 403 is inserted, the thickness of the holding portion 403, and the like. These tool types B are mainly used for maintenance of obstacle nails 200 and the like facing a winning opening called a life nail such as designated nails 204 to 208.

The maintenance tool 400 of the tool type C is a maintenance tool 400 mainly used for maintenance of the designated nail 205. In this embodiment, a mode in which two types of tool types C are illustrated is illustrated, but the present invention is not limited to this, and the obstacle formed in the holding portion 403 also for the tool type C. Various types may be provided depending on the width and shape of the groove through which the nail 200 is inserted, the thickness of the holding portion 403, and the like.

Of the maintenance tools 400 used in this embodiment, typical maintenance tools 400 are shown in detail in FIGS. 28 to 30. 28 to 30 include a six-view view, a cross-sectional view, a reference perspective view, a usage state reference perspective view, and the like of the maintenance tool.

Explaining an example of these maintenance tools 400, for example, in the maintenance tool 400 of the tool type B-1, as shown in FIG. 9, the holding portion 403 holding the body portion 200a has a substantially horizontally long rectangular shape in the front view. On the left and right sides of the front surface, recessed grooves 411L and 411R having left and right dimensions at intervals wider than the diameter φ1 (outer diameter) of the body portion 200a are formed so as to form a rectangular parallelepiped shape. A rod-shaped portion 401 is connected to the central portion of the holding portion 403 in the left-right direction of the upper surface, and the sandwiching portion 403 is provided so as to be substantially orthogonal to the rod-shaped portion 401.

Further, the left and right side corners of the holding portion 403, the inner side corners of the upper and lower openings of the concave grooves 411L and 411R, the outer side corners of the lower openings of the concave grooves 411L and 411R, and the lower surface of the holding portion 403. The left and right side corners are chamfered.

By chamfering the corners of each side in this way, the obstacle nail 200 and the game board surface 2a may be damaged when the body portion 200a is sandwiched by the sandwiching portion 403 and maintenance work is performed. Is prevented.

The obstacle nail maintenance device 300 configured in this way is the process S4 of the plurality of obstacle nails 200 placed on the game board surface 2a using the maintenance tool 400 in the process S5 in the manufacturing process of the game board 2 described above. The first maintenance, in which the obstacle nail 200 in which the abnormality was detected in the above, is maintained based on the first maintenance data, and the second maintenance, in which the designated nails 204 to 208 specified in advance in the process S7 are maintained based on the second maintenance data, are performed. Do.

Next, the contents of the second maintenance of the designated nails 204 to 208 performed by the obstacle nail maintenance device 300 in step S7 will be described with reference to FIGS. 9, 13 to 15. In the following, the second maintenance content of the designated nail 204 will be described as an example, and since the second maintenance content of the other designated nails 205 to 208 is the same, the description will be omitted.

As shown in FIG. 9, when the left and right obstacle nails 200, which are designated nails 204, are driven by the nail gun 16, the left and right obstacle nails 200 are oriented in the Z-axis direction orthogonal to the game board surface 2a. It is tilted upward by about 4 degrees. Further, at the set position, the separation dimension L2 on the base end side and the separation dimension L3 on the head 200b side of the body portion 200a of each of the left and right obstacle nails 200 are the same about 10.5 mm (L2 = about 10.5 mm, L3). = About 10.5 mm). That is, the left and right obstacle nails 200 are driven so that their body portions 200a are substantially parallel to each other. In the second maintenance, the distance between the left and right obstacle nails 200 of the designated nail 204 is gradually widened from the base side toward the head 200b side, and the head 200b is arranged at the designated position where the separation dimension L3 is about 12 mm. It is based on the data.

Based on the second maintenance data received from the management computer 500, the obstacle nail maintenance device 300 operates the holding portion 403 of the maintenance arm 301 by a drive source (not shown) to maintain the designated nail 204.

The second maintenance data is based on the humidity / temperature data obtained from the hygrometer / thermometer described above by the management computer 500 when servicing the designated nail 204 of the game board 2, for example, the game board 2. When the material is a veneer plate, the water content of the veneer plate is calculated, and the operation pattern data for the veneer plate that operates the holding portion 403 of the maintenance arm 301 based on the water content is included. In this way, since the designated nail 204 of the plywood game board 2 can be maintained according to the change in the indoor environment (humidity / temperature) in the factory, it is possible to prevent the veneer plate from being damaged during the maintenance work of the designated nail 204. , Maintenance accuracy is improved.

Further, as the maintenance tool 400, a plurality of types of maintenance tools 400 having dimensions and shapes corresponding to the type of the game board 2 and the target obstacle nail 200 are prepared, and the obstacle nail 200 to be maintained It is said that it can be replaced accordingly. The selection and replacement operation of the maintenance tool 400 is included in the second maintenance data, and the maintenance arm 301 automatically performs the operation according to the obstacle nail 200 to be maintained. It may be replaced manually by a person.

The obstacle nail maintenance device 300 drives the maintenance arm 301 in a predetermined operation pattern based on the received second maintenance data, and moves the holding portion 403 from the initial drive position to the arrangement position of the designated nail 204 to be maintained. The pinching portion 403 is moved above the game board 2 so as not to come into contact with the obstacle nail 200.

Next, as shown in FIG. 9A, the holding portion 403 is lowered to the front side of the designated nail 204 so that the openings of the concave grooves 411L and 411R face the designated nail 204 side. Then, as shown in the direction of the white arrow in FIG. 9A, the sandwiching portion 403 is moved rearward, and the body portions 200a of the left and right obstacle nails 200 are fitted into the concave grooves 411L and 411R, respectively. Place in one position. As a result, the body portions 200a of the left and right obstacle nails 200 are sandwiched by the concave grooves 411L and 411R. At this predetermined position, the rod-shaped portion 401 is tilted upward by a predetermined angle (about 4 degrees) with respect to the Z axis (perpendicular line) as shown in FIG. 9A.

At the first position, as shown in FIG. 9A, the lower surface of the holding portion 403 is separated from the game board surface 2a, and the separation dimension L4 is about 2.5 mm (L10 = 2.5 mm). That is, the holding portion 403 is arranged at a position on the body portion 200a on the base side closer to the game board surface 2a than the head portion 200b. Further, the rod-shaped portion 401 is arranged in a state of being tilted upward by a predetermined angle θ1 (θ1 = 4 degrees) with respect to the Z axis (perpendicular line) so as to be parallel to the body portion 200a of the obstacle nail 200. Further, the vertical dimension L5 of the holding portion 403 is shorter than the length L1 from the game board surface 2a to the head 200b of the obstacle nail 200 (L5 <L1), and the holding portion 403 and the head of each obstacle nail 200. Since it is separated from the 200b, the holding portion 403 can be slid and moved toward the head 200b side.

Next, as shown in FIG. 9B, the holding portion 403 is divided into a plurality of times while swinging the rod-shaped portion 401 left and right at a predetermined angle with reference to the center position CP in the left-right direction on the lower surface of the holding portion 403. Move to.

Specifically, the pinching portion 403 is tilted by tilting the rod-shaped portion 401 toward the right side by a predetermined angle θ2 (θ2 = about 13.15 degrees) with reference to the center position CP in the left-right direction on the lower surface of the pinching portion 403. In this state, the operation is stopped for a predetermined period (for example, about 0.6 seconds). Next, the sandwiching portion 403 is moved by the first movement amount (for example, about 0.35 mm) from the first position in a direction inclined upward by about 4 degrees with respect to the Z-axis direction, and is arranged at the second position. As shown in 9 (B), the sandwiching portion 403 is tilted by a predetermined angle θ2 (θ2 = about 13.15 degrees) with the rod-shaped portion 401 facing the left side with respect to the central position CP, and then returned to the Z axis, and then further. Tilt a predetermined angle θ3 (θ3 = about 12.25 degrees) toward the left side, and stop the operation for a predetermined period (for example, about 0.6 seconds) in the tilted state.

In this way, when the holding portion 403 is tilted in the left-right direction with respect to the central position CP, the obstruction nail 200 on the direction side in which the rod-shaped portion 401 is shaken has a larger bending angle than the obstruction nail 200 on the other side. By repeating the process a plurality of times, the distance between the obstacle nails 200 of the designated nails 204 is gradually widened from the base side to the head 200b side. By such a second maintenance, the head 200b of each of the designated nails 204 is arranged within the allowable range of the designated position.

Next, the obstacle nail maintenance device 300 performs a second inspection for determining whether or not the head 200b of the designated nail 204 for which the second maintenance has been performed is arranged within the allowable range of the designated position. In this second inspection, in addition to whether or not the head 200b of the second repaired obstacle nail 200 is arranged within the allowable range of the designated position, the bending condition of the body portion 200a of the obstacle nail 200 is normal. Judge whether or not.

In this second inspection, the obstacle nail maintenance device 300 first replaces the maintenance tool 400 with the inspection tool 600 shown in FIG. The inspection tool 600 is composed of a rod-shaped portion 601 made of a metal rod-shaped member having a diameter of about 6 mm (φ10 = about 6 mm) and a measuring portion 602 attached to the lower end side of the rod-shaped portion 601 and made of a metal material. It is mainly composed. The measuring unit 602 has a base portion 602a fixedly installed on the lower end side of the rod-shaped portion 601 and a moving portion 602b provided so as to be movable relative to the base portion 602a. As shown in FIG. 15, the moving portion 602b has a plate-shaped piece extending forward from the lower end of the rod-shaped portion 601, and the tip of the plate-shaped piece has a first contact side 602L and the first contact side 602L. A substantially V-shaped notch 603 in a plan view is formed having a second contact side 602R arranged so as to intersect the contact side 602L.

The measuring unit 602 configured in this way can measure the shearing force with respect to the base portion 602a and the direction in which the shearing force is applied by moving the moving unit 602b with respect to the base portion 602a in the XYZ axis direction. It also constitutes a strain gauge type sensor). The valley of the substantially V-shaped notch 603 is the base point RP.

Next, as shown in FIG. 14, using the inspection tool 600, the XY-axis directions at a plurality of locations (in this embodiment, two inspection points P1 and P2) of the body portion 200a of the obstacle nail 200 in the Z-axis direction. Measure the position (coordinates) of. Then, a calculation unit (not shown) provided on the base unit 602a detects the degree of bending of the obstacle nail 200 based on the position data (coordinate data).

Specifically, as shown in FIG. 15A, the base point RP of the inspection tool 600 is arranged at the inspection start position corresponding to each of the inspection points P1 and P2. Subsequently, as shown in FIG. 15B, the inspection tool 600 is moved in the XY axis direction (horizontal direction) so that the base point RP is arranged at the designated position. That is, if the designated nails 204 to 208 are arranged within the allowable range of the designated position by the second maintenance, the inspection of the base point RP is started without the first contact side 602L and the second contact side 602R contacting the body portion 200a. It can be moved from a position to a specified position.

However, when the obstacle nail 200 is not arranged within the allowable range of the designated position, the obstacle nail 200 is placed on either one of the first contact side 602L and the second contact side 602R (for example, the second contact side 602R). Upon contact, pressure acts in the direction of the dotted arrow in FIG. 15B, and the moving portion 602b moves with respect to the base portion 602a. Therefore, the shearing force with respect to the base portion 602a and the direction in which the shearing force is applied are measured. The obstacle nail maintenance device 300 guides the inspection tool 600 in a direction in which the shearing force and its direction decrease (the direction in which the value becomes the minimum value). The above operation is repeated, and as shown in FIG. 15C, the base point RP of the inspection tool 600 is arranged at a position where it abuts on the obstacle nail 200. The obstacle nail maintenance device 300 completes the second maintenance including the above-mentioned second inspection result information including the movement amount and the movement direction in which the base point RP of the inspection tool 600 has moved to the position where the base point RP abuts on the obstacle nail 200. The data is transmitted to the management computer 500.

The management computer 500 (CPU502) that has received the second inspection result information (second maintenance completion data) moves the inspection points P1 and P2 with respect to the designated position in the XY axis directions based on the second inspection result information. Identify the amount of deviation. That is, when the management computer 500 (CPU502) contacts the first contact side 602L or the second contact side 602R while moving the base point RP between the first contact side 602L and the second contact side 602R toward the designated position. The degree of bending of the body portion 200a is specified based on the amount of deviation from the designated position at each of the inspection points P1 and P2 according to the load applied to the body.

As described above, the management computer 500 (CPU502) not only determines the amount of deviation of the obstacle nail 200 in the XY-axis direction with respect to the designated position of the head 200b, but also determines the position different from that of the head 200b in the Z-axis direction. By determining the amount of deviation in the XY axis direction with respect to the designated position of the body portion 200a at each of the inspection points P1 and P2, the degree of bending of the body portion 200a of the obstacle nail 200 is specified.

Further, by specifying the degree of bending of the obstacle nail 200 from the amount of deviation in the XY axis direction with respect to the designated position of the body portion 200a at each inspection point P1 and P2, the length of the head portion 200b of the obstacle nail 200 from the game board surface 2a. The dimensions can be specified. That is, even if the head portion 200b does not deviate from the set position in the XY axis direction, it is possible to grasp a problem that the body portion 200a is bent, so that the planted state of the obstacle nail 200 can be inspected with high accuracy.

Regarding the fault nail 200 in which an abnormality is detected in the second inspection performed after the completion of the second maintenance in step S7, the management computer 500 (CPU502) has corrected maintenance data (re-second maintenance data) corresponding to the second maintenance data. ) Is created, and the holding portion 403 of the maintenance arm 301 is operated based on the modified maintenance data. The second maintenance and the second inspection are repeated until the head 200b of the obstacle nail 200 after the second maintenance is placed within the allowable range of the designated position or until the number of times of the second maintenance reaches a predetermined number. , The second maintenance completion data is transmitted to the management computer 500 each time the second maintenance and the second inspection are performed.

Further, in the second embodiment, in the second inspection, the management computer 500 (CPU502) has the first contact side 602L while moving the base point RP between the first contact side 602L and the second contact side 602R toward the designated position. Alternatively, an embodiment has been exemplified in which the degree of bending of the body portion 200a is specified based on the amount of deviation from the designated position at each inspection point P1 and P2 due to the load applied when the second contact side 602R is contacted. The deviation from the designated position at each inspection point P1 or P2 is based on the amount of movement and the movement direction (movement locus) that the base point RP has moved from the inspection start position to the position where it abuts on the obstacle nail 200. The amount may be measured to specify the degree of bending of the body portion 200a.

Further, in the present embodiment, a mode in which the second inspection is performed using the inspection tool 600 is illustrated, but the present invention is not limited to this, and the second inspection is performed by the camera in the obstacle nail maintenance device 300. You may do so.

Next, the inspection of the obstacle nail 200 performed by the first nail inspection device 17A and the second nail inspection device 17B in steps S4 and S9 will be described with reference to FIG. 15A is a plan view showing the internal structure of the first nail inspection device and the second nail inspection device in FIG. 4, and FIG. 15B is a sectional view taken along line BB of FIG. Since the first nail inspection device 17A and the second nail inspection device 17B in this embodiment have the same configuration, only the configuration of the first nail inspection device 17A will be described, and the description of the configuration of the second nail inspection device 17B will be omitted. To do.

That is, a plurality of cameras 44 (six in this embodiment) fixed along the frame 43 while facing the diagonally downward side are arranged, and the lower part of the frame 43 is moved by the above-mentioned transport device 13. The game board 2 is designed to pass through. When the game board 2 is conveyed below the frame 43, the first nail inspection device 17A stops the transfer device 13 and photographs the entire game board 2 with a plurality of cameras 44. Then, the image data from the plurality of cameras 44 is transmitted to the management computer 500 together with the device number, the read data of the two-dimensional code 15a, and the like.

The management computer 500 (CPU502) integrates the received image data to specify the position (coordinates) of the head 200b of each obstacle nail 200, and the head of each obstacle nail 200 stored in the storage device 505. It collates with the set position (designated position) of 200b and inspects whether or not there is any deviation from the set position.

In this way, in the first nail inspection device 17A, the entire image data is photographed from the periphery of the game board 2 by a plurality of cameras 44 facing diagonally downward, and the image data is integratedly processed by the management computer 500 to perform each obstacle nail. In order to specify the position of the 200, not only the position of each obstacle nail 200 in the front-back and left-right directions (position in the X-axis and Y-axis directions) but also the position in the height direction of each obstacle nail 200 (position in the Z-axis direction). It can be grasped, and the planting state of each obstacle nail 200 can be inspected with high accuracy.

In this embodiment, as an example of grasping the position of each obstacle nail 200, a mode in which each obstacle nail 200 is photographed by a plurality of cameras 44 has been described, but the present invention is not limited thereto. As long as the position of each obstacle nail 200 can be grasped, for example, a sound wave sensor, an optical sensor, or the like may be used.

As described above, in the first inspection, in the first inspection, is the head 200b of each obstacle nail 200 arranged within the allowable range of the set position based on the captured image taken by the camera 44 of the second nail inspection device 17B? In the second inspection, the head 200b of each obstacle nail 200 is arranged within the permissible range of the designated position by the measuring unit 602 (force sensor) provided in the inspection tool 600. By determining whether or not the nail is present, the state of the obstacle nail 200 can be determined in more detail than in the first maintenance, so that maintenance with high accuracy can be performed.

Gauge data and the like are extracted, and various devices perform the above-described steps S3 to S9 based on the information.

Further, the interface for referring to the model registration information list is provided with a new addition button for newly registering the model registration information in the storage device 505. When the new addition button is selected, an interface for newly registering the model registration information in the storage device 505 as shown in FIG. 19 is displayed on the display device 507. When newly registering model registration information in the storage device 505, first enter the item code with a keyboard (not shown) or press the automatic input button and select from the corresponding item code list (not shown) in the interface. And enter. Next, gauge data, which is a unique nail arrangement assigned according to the model of the game board 2, is input. This gauge data is input by pressing the browse button and selecting the corresponding gauge data from the gauge data list (not shown). After that, the above-mentioned camera setting file and various nail accuracy are input. Further, the interface for new registration has a button for setting maintenance data by various maintenance tools 400 (also referred to as an accurate screwdriver) and a maintenance direction and angle of an arbitrary nail.

When the accurate driver maintenance data setting button is selected, an interface for setting the accurate driver maintenance data appears as shown in FIG. This interface has accurate maintenance points (type of designated nail), nail number, center positions X and Y (coordinate data of head 200b), approach direction of maintenance tool 400, maintenance data (operation pattern data), etc. A list of drivers and a gauge data image (see the lower part of FIG. 20) are displayed. Designated nails can be set by inputting the above-mentioned designated nails 204 to 208 or the like in the maintenance location (type of designated nail) displayed on this interface.

In the maintenance data column in this accurate driver list, one operation pattern data can be selected from a plurality of operation pattern data by a pull-down method, and the nail number, center position X, Y (head 200b). (Coordinate data) and the approach direction of the maintenance tool 400 can be set.

In addition, buttons for navel setting, chucker setting, passage gate setting, triangle setting, etc. are arranged at the bottom of the accurate driver list, and by selecting any button, the maintenance location associated with the button is accurate. Selected in the driver list. When an arbitrary maintenance location is selected from this accurate driver list (in this embodiment, a navel nail is selected), the area around the obstacle nail 200 selected in the gauge data image is colored, and which maintenance location is selected by the operator. It is easy to grasp. In this embodiment, when an arbitrary maintenance location is selected from the accurate driver list, the area around the obstacle nail 200 selected in the gauge data image is colored, but the present invention is not limited to this, and the maintenance location is not limited to this. If it is easy to grasp whether or not is selected, the periphery of the obstacle nail 200 selected in the gauge data image or the obstacle nail 200 itself may be lit or blinking.

When an operation such as double-clicking is performed with an arbitrary maintenance location selected in the accurate driver list, as shown in FIG. 21, for setting maintenance data for the arbitrary maintenance location (in this embodiment, a navel nail). An interface appears. In this interface, the nail swing angle, the nail swing movement amount, the Z-axis direction movement amount, the stop time, and the nail swing speed can be set for each maintenance data (operation pattern data). In this way, various maintenance data (operation pattern data) can be set for each maintenance location (type of designated nail), so that the setting for setting the specific obstacle nail 200 to the desired planting state can be set. It's simple.

Further, when the button for setting the maintenance direction and angle of the arbitrary nail is selected in the above-mentioned interface for new registration, an interface for setting the maintenance direction and angle of the arbitrary nail appears as shown in FIG. .. This interface includes a list of registered lists such as nail number, center position X, Y (coordinate data of head 200b), height, direction, angle, type of driver (type of maintenance tool), and gauge data image. (See the lower part of FIG. 22) and is displayed. In the gauge data image in this interface, the specific obstacle nail 200 is colored, and the obstacle nail 200 with the nail number selected in the registration list list is distinguished (in this embodiment, it is circled). , It is easy for the operator to grasp the obstacle nail 200 being selected. According to this, regardless of the type of the specific obstacle nail 200, it becomes possible to maintain each obstacle nail 200, so that the specific obstacle nail 200 can be maintained in a desired planting state in more detail. You can do it.

Next, the correction data of this embodiment stored in the storage device 505 will be described with reference to FIG. 23. The correction data is for improving the maintenance accuracy of the obstacle nail 200, and even if the same maintenance is actually performed in the obstacle nail maintenance device 300, if the maintenance position is different, different maintenance results may be obtained. In addition, for example, the distance between the obstacle nails 200 may be narrow at a position close to the turntable 312, and the distance between the obstacle nails 200 may be wide at a position far from the turntable 312, so that the maintenance result may be biased. Further, the difference and the bias of the maintenance result depending on the maintenance position are different depending on the obstacle nail maintenance device 300, and there are so-called individual differences. Therefore, the maintenance accuracy of the obstacle nail 200 can be improved by eliminating the non-uniformity of the maintenance result due to the maintenance position and individual difference by the correction data or the like.

Therefore, the correction data is desired in the actual second maintenance by correcting the desired dimension when the distance between the obstacle nail 200, particularly the obstacle nail 200 of the designated nails 204 to 208 is set to a desired dimension. It is the data to be maintained to the size of, and is set by the measured value of the standard maintenance at each position of the table 302 on which the game board 2 is placed.

Specifically, as shown in FIG. 23, the area on the table 302 on which the game board 2 which is the maintainable position of the present invention is placed is from 10 steps in the front-rear direction and 5 rows A to E in the left-right direction. A 50-divided (10 × 5) region is set, and in each of the divided regions, each condition such as material, tool, plate temperature, and humidity is changed, and the interval of the obstacle nail 200 is 12. The standard maintenance to be maintained at 00 mm is executed by the obstacle nail maintenance device 300, the interval between the obstacle nails 200 in each area is actually measured, and the correction value is calculated from the actually measured data. The correction value may be calculated from the average value of standard maintenance performed a plurality of times (for example, 10) under the same maintenance conditions (material, tool, plate temperature, humidity, etc.).

As shown in FIG. 23, the intervals of the obstacle nails 200 that are standardized in each of these areas are, for example, some areas having the same interval as 12.00 mm, some areas narrower than 12.00 mm, and 12. There is an area wider than 00 mm, and the correction data is calculated from the actual spacing of these obstacle nails 200 and the set value of 12.00 mm for standard maintenance.

That is, as an example of these correction data, for example, a value obtained by dividing the standard maintenance setting value of 12.00 mm by an actual measured value can be used. Specifically, if the measured value is 12.05 mm, 0.9959, which is the value obtained by dividing 12.00 mm by 12.05 mm, is the correction value data, and the interval that you actually want to maintain is 11.50. If it is millimeters, the value obtained by multiplying the 11.50 millimeters by the correction data may be set as the interval indicated in the maintenance.

As described above, these correction data are created for each combination of various conditions such as the material of the game board 2, the plate temperature, and the humidity, and are stored in the storage device 505.

Therefore, when the management computer 500 executes the second maintenance, the correction data that matches the conditions such as the plate temperature and humidity transmitted from the obstacle nail maintenance device 300 among the correction data is the maintenance target. The correction data of the area corresponding to the position where the obstacle nail 200 is driven is specified, and the interval indicated by the specified correction data is corrected to create the second maintenance data.

In this embodiment, the correction data as described above is used, but the present invention is not limited to this, and the ratio (%) of the difference from the actual dimensions is calculated. However, in reality, correction data that facilitates the calculation of the second maintenance data to be created may be used, such as using the ratio (%) as the correction value.

In this embodiment, in the management computer 500, these second maintenance maintenance methods are maintained by either a maintenance method using the above-mentioned correction data or a maintenance method not using the correction data. Can be set on the nail maintenance method setting screen displayed on the display device 507 by executing a predetermined setting operation.

As shown in FIG. 24, the nail maintenance method setting screen of this embodiment is provided with check boxes corresponding to the nail maintenance methods "one device completion method" and "multiple device sharing method". The check box can be exclusively selected.

The "1 device completion method" is a maintenance method in which all the maintenance of the game board 2 of 1 is executed in each obstacle nail maintenance device 300 by using the above-mentioned correction data. That is, as illustrated in FIG. 23, each obstacle nail maintenance device 300 has a different area where good maintenance can be performed, and each obstacle nail maintenance device 300 has a habit. Therefore, for areas other than these areas where good maintenance can be performed, the correction data is used to correct the second maintenance data instructed so that the maintenance is good, and the obstacle nail maintenance device 300 of 1 is used for all areas. This is a maintenance method for completing the second maintenance of the obstacle nail 200 in the area of.

On the other hand, in the "multiple device sharing method", a plurality of obstacle nail maintenance devices 300 share the range of the second maintenance, and each obstacle nail maintenance device 300 has a habit (error) of maintenance. However, since the obstacle nails 200 in the same range of each game board 2 are maintained by the same habit (error), it is a maintenance method that can suppress the variation in the quality of each game board 2.

Therefore, on the nail maintenance method setting screen, as shown in FIG. 24, the device number of the obstacle nail maintenance device 300 arranged on the production line 12 and the device number are included in the item of "multiple device sharing method". The range to be secondly maintained by the obstacle nail maintenance device 300 can be selected and set from the six ranges R1 to R6. The ranges R1 to R6 are ranges obtained by dividing the range of the game board 2 into six, and when the range is selected, the measurement data of the standard maintenance of the corresponding obstacle nail maintenance device 300 (see FIG. 23). It is preferable to select a region in which the measured interval is within a predetermined reference value from 12.00 mm, for example, ± 0.02 mm. However, it is not necessary to satisfy that all the areas corresponding to these ranges are within the predetermined reference value, and if there is no range in which all the areas are within the predetermined reference value, the area is within the predetermined reference value. You may choose a range that has many areas that satisfy a certain condition. It should be noted that these selections may be automatically selected by the management computer 500 instead of being input by the operator by operation.

Further, the reference value is not limited to the above, and may be appropriately determined according to the properties of the product, the type of the obstacle nail 200, and the like.

In this way, when the "multiple device sharing method" is set as the maintenance method on the nail maintenance method setting screen, the management computer 500 displays the nail maintenance method setting screen for each obstacle nail maintenance device 300. The obstacle nail 200 in the range R1 to R6 set in each obstacle nail maintenance device 300, that is, the range having a region satisfying the predetermined reference value, is secondly maintained, and the other range is provided. By transmitting the second maintenance data instructing that the second maintenance is not performed for the obstacle nail 200, each obstacle nail maintenance device 300 executes the second maintenance in a different range. Since the second maintenance data in these "multiple device sharing method" is not corrected by the correction data unlike the second maintenance data in the "one device completion method", these second maintenance data are created in the management computer 500. The processing load of the processing to be performed can be reduced, and the second maintenance data can be quickly transmitted to the obstacle nail maintenance device 300.

In the "multiple device sharing method", as described above, even if there is a habit (error) in maintenance, all the game boards 2 will include the same error, and there will be variations among the game boards 2. Since it does not occur, a range that does not include a large number of areas within a predetermined reference value may be specified as long as it does not include an area that causes poor maintenance.

In the example shown in FIG. 24, the No. 01 obstacle nail maintenance device 300 installed on the production line 12 secondly maintains the range R1, the No. 02 obstacle nail maintenance device 300 secondly maintains the range R3, and the No. 03 The setting example in which the obstacle nail maintenance device 300 of No. 2 maintains the range R4 second, the obstacle nail maintenance device 300 No. 05 maintains the range R6 second, and the obstacle nail maintenance device 300 No. 06 maintains the range R5 second. Is shown, and a mode in which the six obstacle nail maintenance devices 300 Nos. 01 to 06 share the second maintenance is illustrated.

Since the maintenance habit (error) of these obstacle nail maintenance devices 300 usually changes depending on the number of times the maintenance is performed, the maintenance habit (error) is measured again and shared. There is an item for setting a rotation study maintenance counter to specify the timing to consider changing the range to be performed (rotation), and the number of maintenance until the next time to consider changing the range to be shared (rotation) is set for this item. By inputting, the value of the rotation examination maintenance counter is decremented by 1 each time the second maintenance is executed by each obstacle nail maintenance device 300, and the rotation of any of the obstacle nail maintenance devices 300 that shares the second maintenance. When the examination maintenance counter becomes "0", the standard maintenance is executed again and the range to be shared is reset. That is, in this embodiment, the measurement (detection) by the standard maintenance is executed every time the rotation study maintenance counter becomes "0", which is the execution condition for executing the remeasurement (redetection).

In this embodiment, the execution condition for executing the remeasurement (redetection) is illustrated as the number of executions of the second maintenance, but the present invention is not limited to this, and these executions are performed. The condition may be executed at a fixed cycle every time a predetermined period elapses.

Next, the nailing data table of this embodiment stored in the storage device 505 will be described. As shown in FIG. 25, the nailing data table of this embodiment shows the serial number of the game board 2 in which the nailing machine 16 has the same number as the device number of each nailing machine 16. Information (data) such as numbers, dates at the time of nailing, temperature and humidity is stored and managed.

Therefore, the management computer 500 can identify the nailing machine 16 on which the obstacle nail 200 of the game board 2 is placed from the serial number of the game board 2 by the nailing data table, and the nailing machine 16 has an obstacle. It is also possible to specify the date on which the nail 200 was placed and the manufacturing conditions such as temperature and humidity at that time.

It should be noted that these data include temperature and humidity data included in the nailing work completion data transmitted together with the device number and the reading data of the two-dimensional code 15a when the driving of the obstacle nail 200 is completed in the nailing machine 16. Although stored, the present invention is not limited to this, and the temperature / humidity data is included in the data at the time of requesting data transmission transmitted when the nailing machine 16 starts driving, and the data transmission is performed. The temperature / humidity data included in the data at the time of request may be stored.

Further, although not shown in FIG. 25, in the storage device 505 of the management computer 500, similarly to the nailing data table, the obstacle nail maintenance device having the same number is associated with the device number of each obstacle nail maintenance device 300. The obstacle nail maintenance data table that stores and manages the serial number of the game board 2 where the final second maintenance was performed in 300 and information (data) such as the date, temperature, and humidity at the time of maintenance is also stored. From the serial number of the game board 2, the second-maintained obstacle nail maintenance device 300 of the obstacle nail 200 of the game board 2 can be identified by the obstacle nail maintenance data table, and the obstacle nail 200 can be identified in the obstacle nail maintenance device 300. It is also possible to specify the date of the second maintenance and the manufacturing conditions such as temperature and humidity at that time.

It should be noted that these data include temperature and humidity data included in the second maintenance completion data transmitted together with the device number and the reading data of the two-dimensional code 15a when the above-mentioned second maintenance is completed in the obstacle nail maintenance device 300. Is stored. As described above, in this embodiment, the serial number, the temperature / humidity data, and the like included in the two-dimensional code 15a are associated with the device number, which is the device number of the fault nail maintenance device 300 that has undergone the second maintenance. Although it is stored in the data table, the present invention is not limited to this, and the obstacle nail maintenance device for which the first maintenance is performed is the same as the obstacle nail maintenance data table for the second maintenance. From 300, when the first maintenance is completed, the reading data and temperature / humidity data of the two-dimensional code 15a of the game board 2 that has undergone the first maintenance, which is transmitted together with the device number of the obstacle nail maintenance device 300, are included. Based on the first maintenance completion data, the serial number, temperature and humidity data, etc. included in the completion data are associated with the device number of the obstacle nail maintenance device 300 that has undergone the first maintenance. By storing the information in the maintenance data table, the information related to the first maintenance may be specified in the same manner as in the second maintenance, and may be printed out in the nail spacing measurement report described later.

Further, in this embodiment, when the second maintenance (first maintenance) is repeatedly executed, the data for the final second maintenance (first maintenance) is stored in the obstacle nail maintenance data table. However, the present invention is not limited to this, and when these second maintenance (first maintenance) are repeatedly executed, the data for each second maintenance (first maintenance) is also an obstacle nail maintenance data table. You may memorize it in.

Further, the obstacle nail maintenance data table may store the maintenance method in the obstacle nail maintenance device 300. Furthermore, when the "1 device completion method" using the correction data was executed as the second maintenance method, the obstacle nail 200 targeted for the second maintenance was used for the maintenance of the obstacle nail 200. The correction data (correction value) may also be stored so that it can be confirmed later. When the "multiple device sharing method" is executed, the obstacle nail maintenance in which the second maintenance of each range R1 to R6 is performed. Individual difference information such as an error (individual difference) and correction data (correction value) in the range of the device 300 may also be stored so that it can be confirmed later. Further, these maintenance methods and individual difference information may be described in the nail-to-nail measurement report shown in FIG. 27. By doing so, in the obstacle nail maintenance data table, the game board 2 is associated with the serial number which is the identification information that can be individually identified, and the book about the second maintenance of the obstacle nail 200 of the game board 2 is made. The correction data, which is the individual difference information of the invention, will be stored and managed.

Further, in the second image inspection table of this embodiment, as shown in FIG. 26, the first inspection is performed in the second nail inspection device 17B having the same number in association with the device number of each second nail inspection device 17B. Information (data) such as the serial number of the game board 2 performed, the date at the time of the inspection, and the temperature and humidity at the time of the inspection are stored and managed.

Therefore, the management computer 500 can identify the second nail inspection device 17B that first inspected the game board 2 from the serial number of the game board 2 by the second image inspection table, and the second nail inspection device 17B. It is also possible to specify the manufacturing conditions such as the date of inspection, temperature and humidity in.

Although the second image inspection table is illustrated in FIG. 26, the storage device 505 of the management computer 500 also stores the first image inspection table similar to the second image inspection table. 1 In the image inspection table, the serial number of the game board 2 inspected by the first nail inspection device 17A of the number, the date at the time of inspection, and the date in association with the device number of each first nail inspection device 17A. Information (data) such as temperature and humidity at the time of inspection is stored and managed, and the first nail inspection device 17A, which first inspects the game board 2 from the serial number of the game board 2, is subjected to the first image inspection. Not only can it be specified by the table, but also the manufacturing conditions such as the date, temperature and humidity of the primary inspection by the first nail inspection device 17A can be specified.

In this embodiment, the nail-to-nail measurement sheet shown in FIG. 27 is printed out by the printer 508 based on various data stored in the storage device 505 of the management computer 500, and the pachinko machine which is the purchaser of the game board 2 is printed out. It is provided to the purchaser of the game machine 1.

As shown in FIG. 27, the nail-to-nail measurement sheet of this embodiment has a front view of the game board 2 printed on the left half of the paper, and the equipment, conditions, and designated nails manufactured and maintained on the left half of the paper. Information on the nails and information on a predetermined and highly important obstacle nail 200 are printed.

Specifically, as shown in FIG. 27, the symbols A to F are printed on the front view of the game board 2 so that it can be understood which part of the game board 2 the A to F point to. At the same time, the specified value of the size of the winning opening in the parts A to F is printed on the lower part of the paper.

Further, in the front view of the game board 2, all the obstacle nails 200 placed on the game board are printed in circles, and data such as the angle and direction of the obstacle nails 200 are required. The highly important obstacle nail 200 is displayed as a black circle, and the numbers [1] to [22] are printed in the vicinity thereof.

Further, on the right side of the specified value display of the size of the winning opening, an explanatory diagram explaining which position interval in the obstacle nail 200 is which name is printed.

At the top of the nail-to-nail measurement report, the title of the "nail-to-nail measurement report", the printed date, and the model name are printed. In addition, each item data such as serial number, development number, and nailing data name is printed on the upper right part of the paper.

Further, as shown in FIG. 27, information on nailing of "nail gun date", "nail gun machine number", and "plate thickness" is printed on the right side of the paper. Below that, after the nail position of "image inspection date", "nail position measuring machine", "nail height accuracy MAX", "nail height accuracy MIN", "temperature", "humidity", "plate temperature" Information about the first image inspection of is printed.

Below that, information about nail maintenance such as "nail maintenance date", "nail maintenance machine", "temperature", "humidity", and "plate temperature" is printed, and below that, "image inspection date". , "Nail position checker", "Temperature", "Humidity", "Plate temperature" Information about the final confirmation image inspection is printed.

Further below, information regarding the spacing between the winning openings A to F shown in the front view on the left side of the paper is printed.

Further, on the right edge of the paper, information on the "angle" and "direction" of the obstacle nails 200 [1] to [22] shown in the front view on the left side of the paper is printed in association with the number of each obstacle nail 200. Has been done.

The "angle" is described so that the angle perpendicular to the game board surface 2a is "0 degree", and the angle becomes larger as the tip of the obstacle nail 200 is inclined toward the upper side of the game board surface 2a. It is shown in the figure that the time indicated by the hands of the clock is indicated by the corresponding direction in the top view of the obstacle nail 200 with respect to the "direction". There is.

As described above, as shown in FIG. 27, a lot of information regarding the maintenance of the obstacle nail 200 is printed on the nail-to-nail measurement sheet of the present embodiment, but the present invention is limited to this. The type, content, and display method of these printed maintenance information can be changed as appropriate. That is, as information on maintenance, as information on maintenance of the obstacle nail 200, which device was used for nailing and maintenance, conditions such as temperature and humidity when nailing and maintenance were performed, and obstacles after maintenance. Only one of the information such as the angle and direction of the nail 200 and the distance between the winning openings may be used.

Further, in the present embodiment, as shown in FIG. 27, a form in which a person concerned such as a purchaser of the pachinko gaming machine 1 outputs a nail-to-nail measurement sheet that can be directly read is illustrated, but the present invention illustrates the form. The present invention is not limited to this, and for example, the page data of these inter-nail measurement sheets is stored in the management computer 500 in association with page-specific information such as the serial number of the game board 2 to which the inter-nail measurement report corresponds. Then, the person concerned outputs only the encrypted information that cannot be directly read, such as a barcode that encodes the page specific information or a symbolized two-dimensional code, and outputs the encrypted information. , The page specific information is extracted by reading with a predetermined terminal, and the page data of the nail spacing measurement report stored in the management computer 500 is obtained and displayed in association with the extracted page specific information. You may. Further, instead of the management computer 500, the page data of the nail-to-nail measurement report is stored in a specific management server computer in association with the page specific information such as the serial number of the game board 2, and the specific management server computer. By accessing and entering the page specific information on the dedicated page, the page data of the nail-to-nail measurement report will be distributed and displayed on terminals (for example, smartphones and tablets) that can be used by the parties concerned. It may be. In this way, by allowing the parties concerned to output only the encrypted information that cannot be read directly, the output information related to maintenance is less likely to be falsified, so it is possible to improve the security of the information related to maintenance. it can.

When outputting a bar code in which these page specific information is encoded or a symbolized two-dimensional code, the two-dimensional code 15a shown in FIG. 17 is not output only in these bar codes and two-dimensional codes. Along with the bar code and the two-dimensional code, some information on maintenance described in the inter-nail measurement sheet specified from the bar code and the two-dimensional code, for example, the date of nailing and By printing out the data of the measured values such as the nail maintenance date and the winning opening, the information about the maintenance that is printed out together with these barcodes and two-dimensional codes can be directly obtained without using a predetermined terminal or the like. It may be made readable. By doing so, even when the predetermined terminal cannot be used, information on maintenance can be confirmed.

As described above, according to the present embodiment, as shown in FIG. 11, in the obstacle nail maintenance device 300, depending on the type of the second maintenance (nail type, maintenance tool type, maintenance deformation amount (maintenance operation)). Since different holding controls are performed by determining different clamp control patterns, the game board can be preferably held, so that different types of maintenance can be appropriately performed. The type of maintenance is limited to the type illustrated in this example, and may be a type different from the type illustrated in this example. Specifically, instead of the maintenance deformation amount (movement amount of the maintenance tool), the maintenance may have different moving speeds of the maintenance tool, the movement route of the maintenance tool, the position of contacting the obstacle nail 200, or the like. ..

Further, according to the present embodiment, in the table 302 of the obstacle nail maintenance device 300, the game board 2 has a guide pin having a diameter smaller than the inner diameter of the guide hole inserted into the guide hole formed in the game board 2. In this state, it is urged in the left-right horizontal direction intersecting the guide pin, so that the position accuracy of the held game board can be improved.

Further, according to the present embodiment, in the first maintenance and the second maintenance, after the first maintenance (primary maintenance) is performed, the state of the maintained obstacle nail 200 is detected, and the detected state is a predetermined appropriateness. It is determined whether or not it is in a state, and if it is not in a predetermined proper state, it is redeveloped differently from the initial maintenance based on the detected state, specifically, as shown in FIG. , In the first redevelopment, maintenance with a modified example (maintenance amount), which is an example of maintenance operation, changed, in the second redevelopment, the maintenance tool 400 used was changed, and in the third redevelopment, obstacle nail maintenance. Since the maintenance of the device 300 is changed, it is possible to prevent the occurrence of obstacle nails due to poor maintenance.

In the above embodiment, the management computer 500 exemplifies the determination of whether or not the detected state is in a predetermined appropriate state, but the present invention is not limited to this. In the case where these determinations are made on the obstacle nail maintenance device 300 side, or the state of the obstacle nail 200 after maintenance is detected by the first nail inspection device 17A, the second nail inspection device 17B, or the like. May be performed by each of the first nail inspection device 17A and the second nail inspection device 17B, that is, on the device side that detects the state of the obstacle nail 200.

Further, according to the present embodiment, if the state of the obstacle nail 200 is not in the predetermined proper state even after the redevelopment is performed a predetermined number of times (three times in the present embodiment), the first maintenance or the second maintenance is performed. Since the maintenance is completed and the product is set to be discharged from the production line 12, re-maintenance (secondary maintenance) is repeated more than necessary to prevent inconveniences such as a decrease in manufacturing efficiency. be able to.

Further, according to this embodiment, as shown in FIG. 23, standard maintenance is performed so that the distance between the obstacle nails 200 in different regions (positions) on the game board surface 2a is 12.00 mm, which is the standard state (12.00 mm). (Standard maintenance process), the interval of the obstacle nail 200 after the standard maintenance is detected in order to detect the individual difference which is the error between the interval of each obstacle nail 200 which has been standard-maintained and the standard state of 12.00 mm. (Nail state detection step), correction data for each area is created from individual differences obtained by the detection, and if "1 device completion method" is set as the maintenance method in the management computer 500, maintenance is performed. Since the second maintenance is performed based on the second maintenance data corrected by the correction data corresponding to the area (position) where the target obstacle nail 200 is provided, the failure nail 200 with poor maintenance due to the difference in position occurs. Can be prevented.

Further, according to this embodiment, as described above, the standard maintenance (standard maintenance process), the individual difference which is an error between the interval of each obstacle nail 200 to which the standard maintenance is performed and the standard state of 12.00 mm. (Nail state detection process), and when the "multi-device sharing method" is set as the maintenance method in the management computer 500, the individual difference is within a predetermined reference value for good maintenance. The second maintenance of the obstacle nail 200 is performed for the range (any of the ranges R1 to R6) to which the area (position) is, and the area (position) that is not within the reference value, that is, the obstacle nail on the nail maintenance method setting screen. By not servicing the obstacle nail 200 in the range not set for the maintenance device 300 (good partial maintenance process), it is possible to prevent the occurrence of the obstacle nail 200 due to poor maintenance due to the difference in position.

In the above embodiment, the management computer 500 illustrates a mode in which the maintenance method can be selected and set from the "one device completion method" and the "multiple device sharing method", but the present invention is limited to this.
