BACKGROUND OF THE INVENTION
The present invention relates to Open Closed Possible nail holder position detecting function game machine for producing the nailing machine provided with a for detecting the position of the holder arms for the manufacture of a gaming machine such as a pachinko machine.
[0002]
[Prior art]
Among the nailing machines for manufacturing gaming machines, for example, as disclosed in Japanese Patent Publication No. 3-42908, a gaming board is positioned and mounted on a table, and this table is placed in a nail driving position and order based on nail driving data. In accordance with the above, the game board is moved vertically and horizontally in the plane to stop positioning the predetermined position of the game board below the nail holder mechanism, and the nail called the game nail or obstacle nail that is imaginary from the nail supply part to the nail holder mechanism is hammered. There is a known mechanism that drives a game board.
[0003]
[Problems to be solved by the invention]
In the conventional nailing machine, each time a nail is struck in order to prevent the nail holder mechanism from interfering with the nail already driven into the game board on the table when the table moves vertically and horizontally in the plane. In addition, the holder arm that supports the nail of the nail holder mechanism repeats moving and stopping. With this repeated movement or vibration or impact at the time of stopping, the stopping position may be shifted because the nail of the holder arm is driven into the game board. For this reason, the operator visually observes the game boards discharged from the nailing machine one by one, and the base of each nail actually driven into the game board is a gauge that is the previous process of the nail driving process. It is confirmed whether or not it matches with a punch hole (a pilot hole as a reference position for driving a nail) attached to the game board in the press process. If the base of the front nail is aligned with the punch hole, the game board is used as a non-defective product and supplied to the assembly process for attaching the game function parts such as the next windmill, guide rail, and accessory to the game board. If the root of the nail in one is only to shift the punch holes, while removing from the production line the game board as a defective, interrupted the operation of the nailing machine, drive a nail holder over the arm on the game board positions to ensure that no misalignment between the position of the punch holes of the mounted game board on the table, if displaced, is to correct the position of the holder arm. However, since about 300 nails are driven into one game board, the position of the holder arm starts to be corrected after the operator starts checking the nailing position of one game board. In the meantime, the nailing machine has completed the nailing of several game boards, and all of these game boards may become defective. Also, since the nail gripped by the holder arm is driven into the game board by the hammer mechanism, the holder arm is worn by rubbing with the nail, and when replacing the holder arm, use a dedicated positioning jig or gauge, etc. It takes a lot of labor and time.
[0004]
Therefore, the present invention seeks to provide a nailing machine for manufacturing a gaming machine that can detect the positional deviation of the holder arm at an early stage and improve the production efficiency.
[0005]
[Means for Solving the Problems]

According to the nailing machine for manufacturing a gaming machine according to the present invention, from the start of nail driving, a single nail supported by the holder arm is driven into a predetermined position where a nail of a game board mounted on a table is driven by a hammer mechanism. By the end, the position detection means detects the position of the detected portion of the movable arm, and the processing section is movable by comparing the detection value from the position detection means from the start to the end of the nail driving with a preset initial value. Since the correctness of the position of the side arm is judged, it is possible to quickly and accurately detect the correctness of the position of the holder arm, and the production efficiency can be improved, and the detected part is provided on the movable arm. When the nail to be driven by the hammer mechanism is bent, the bending of the nail makes the movable arm open and the position of the detected portion is shifted, so that the bending of the nail can be detected quickly. If the detected portion is provided behind the opening / closing central axis of the movable arm, it is easy to prevent interference between the measurement light or measurement wave of the position detection means and the nail supported by the holder arm.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a first embodiment of the present invention, in which FIG. 1a shows a side view of a nailing machine for manufacturing a gaming machine, and FIG. 1b shows a relationship between protrusions and position detecting means.
[0007]
A nailer for manufacturing a gaming machine will be described with reference to FIG. On the table 2 of the apparatus main body 1 of the nailing machine, a game board 3 which is a target for nailing is positioned and mounted with its design board surface facing upward. At the initial stage when the game board 3 is mounted, the table 2 is stopped at the forward limit position where it is most moved to the front side of the page on the left side of the drawing with respect to the apparatus main body 1. Either a game board sensor (not shown) for detecting the positioning and mounting of the game board 3 or a manual switch (not shown) that is turned on by the operator's operation in place of the game board sensor is used for the game board type signal and nailing. The start signal is output to the control unit 4 incorporating the computer. Then, the computer extracts the driving position and the order from the nailing data corresponding to the model of the game board 3 stored in advance in the storage device of the control unit 4 to control the XY driving unit 6.
[0008]
The XY drive unit 6 moves the table 2 in the vertical and horizontal X and Y directions in the plane, and places a predetermined position of the game board 3 on the set plate 7 above and a nail holder mechanism 8 and a hammer mechanism. Positioning stops below 9. The holder arm 8a of the nail holder mechanism 8 is a nail indicated by a solid line that receives a game nail or a nail 5 called an obstacle nail supplied from the nail supply unit 10 such as a parts feeder to the nail holder mechanism 8 by a drive mechanism (not shown). It moves to the supply side and the nail driving side indicated by the dotted line for driving the nail 5 into the game board 3. The hammer mechanism 9 is moved up and down by a driving mechanism (not shown) on the nail driving side to a nail driving start side which is a rising limit and a nail driving end side which is a lowering limit.
[0009]
Then, the predetermined position of the game board 3 stops positioning below the nail holder mechanism 8 and the hammer mechanism 9, and the nail holder mechanism 8 supports the nail 5 supplied from the nail supply unit 10 on the supply side, and then nails are driven. The nail 5 supported by the nail holder mechanism 8 on the nail driving side is driven into the game board 3 so that a large number of nails 9 to be hit on one game board 3 are obtained. The game board 3 is automatically driven one by one.
[0010]
In the first embodiment, the position of the protrusion 11c provided as the detected portion in the nail holder mechanism 8 is detected during and after the driving of each of a large number of nails 9 to be struck onto one game board 3. When the detected position is different from the predetermined position, the driving operation of the hammer mechanism 9 is interrupted and the abnormality of the position of the holder arm 8a is notified. Therefore, the set plate 7 includes a plurality of non-contact type position detecting means 11a and 11b, the holder arm 8a of the nail holder mechanism 8 includes the protrusion 11c, the control unit 4 includes the processing unit 11d, and the apparatus main body 1 generates an alarm. The processing unit 11d instructs the position detection means 11a and 11b to start measurement by executing position detection control during nail driving and at the end of driving according to the driving position and order. Then, after the holder arm 8a of the nail holder mechanism 8 receives the supply of the nail 5 from the nail supply unit 10 and stops on the nail driving side, the position detection means 11a and 11b detect the position of the projection 11c and the processing unit 11d. Output to.
[0011]
The processing unit 11d determines whether or not the detection position with respect to the protrusion 11c is outside the allowable range set in the treatment unit 11d, and if the detection position is within the allowable range, instructs the control unit 4 to drive the next nail. To do. If the detected position is out of the allowable range, the processing unit 11d instructs the control unit 4 to interrupt the operation of the nailing machine thereafter and instructs the alarm device 12 to notify the abnormality.
[0012]
As shown in FIG. b, one of a pair of left and right holder arms 8a of the nail holder mechanism 8 is attached to the holder base 8b as a fixed arm, and the other holder arm 8a is opened and closed as a movable arm to the holder base 8b. It is rotatably attached by 8c. On the rear end side of the opening / closing center shaft 8c, an elastic body 8d such as a coil spring is inserted and attached to the pair of left and right holder arms 8a. The elastic body 8d applies a spring force in the direction of closing the tip from the opening / closing center 8c to the holder arm 8a that is a movable arm. The tip of the pair of left and right holder arms 8a is individually provided with a nail holding portion 8e that is flat in plan view and a nail holding portion 8f that is V-shaped in plan view. The holder arm 8a, which is a movable arm, is moved by the external force indicated by the arrow P after the nail 5 is driven into the game board 3 by the hammer mechanism 9 until the holder arm 8a starts moving to the retracted position indicated by the solid line. By being pushed and moved in one direction against the elasticity of the elastic body 8d, it opens in one direction around the opening / closing central axis 8c with respect to the fixed side arm. This opening amount is set to the minimum dimension so that the holder arm 8a does not interfere with the nail 5 that has been driven into the game board 3 until then. The position detection means 11a and 11b are arranged so that the laser beam or the ultrasonic wave is different from each other such that the included angle is 90 degrees with respect to the protrusion 11c of the holder arm 8a stopped at the position where the nail 5 is driven into the game board 3. Is irradiated to the projection 11c of the holder arm 8a, the reflected light or reflected wave is received, the position of the projection 11c is detected, and a signal corresponding to the detected position is controlled in FIG. The data is output to the processing unit 11d built in the unit 4.
[0013]
According to the structure of the first embodiment, in order to drive the nail 5 supported by the nail holder mechanism 8 into the game board 3 with the hammer mechanism 9, the holder arm 8a stops at a position where the nail 5 of the game board 3 should be driven. At this time, since the position detecting means 11a and 11b arranged at two different positions detect the position of the protrusion 11c of the holder arm 8b, the position of the protrusion 11c can be detected quickly and accurately.
[0014]
Further, according to the structure of the first embodiment, the position of the projection 11c is detected during the driving for each nail 9 and at the end of the driving, so that the nail 5 driven by the hammer mechanism 9 is bent. The bending of the nail 5 makes the holder arm 8a, which is a movable arm, open, and the detection position of the protrusion 11c shifts. Therefore, the processing unit 11d detects the position abnormality of the protrusion 11c, and the alarm device 12 notifies the abnormality. As a result, the operator can quickly find an abnormal position of the holder arm 8a.
[0015]
Furthermore, according to the structure of the first embodiment, when replacing the holder arm 8a, the operation of the nail driver is stopped, and the nail driver is inched with a manual switch so that the holder arm 8a is attached to the game board 3. When the nail 5 is stopped at the position to be driven and the old holder arm 8a is attached to the holder base 8b instead of the new holder arm 8a, the position detecting means 11a, 11b detects the position of the projection 11c of the new holder arm 8a, It is easy to replace the holder arm 8a by accurately positioning the new holder arm 8a with respect to the holder base 8b so that the detection position is aligned with the predetermined position, and finally fixing the new holder arm 8a to the holder base 8b. Can be done.
[0016]
FIG. 2 shows a second embodiment of the present invention, wherein the projection 11c is provided behind the opening / closing central axis 8c of the holder arm 8a, so that the measurement light or measurement wave of the position detection means 11a, 11b is supported by the holder arm 8a. This makes it difficult for the nail 5 to interfere.
[0017]
In the above embodiment, the case where the set plate 7 is stationary and the table 2 is driven is illustrated and described. However, the table 2 is stationary and the set plate 7 is driven so that the nail holder mechanism 8 and the hammer mechanism 9 The same effect can be obtained by moving the pair in the XY direction or moving the table 2 in the X direction and moving the pair of the nail holder mechanism 8 and the hammer mechanism 9 in the Y direction. In this case, if the nail supply unit 10 is assembled to the set plate 7 and moved in the same manner as the group consisting of the nail holder mechanism 8 and the hammer mechanism 9, the nail supply operation to the nail holder mechanism 8 becomes smooth.
[0018]
In the above embodiment, the holder base 8b of the nail holder mechanism 8 is moved between the nail supply side and the nail driving side, but the holder base 2 is brought into a stationary state at one position where the nail supply side coincides with the nail driving side. Alternatively, the table 32 may be moved in the XY directions to perform nailing.
[0019]
In the above-described embodiment, the protrusion 11c is the detected portion. However, a part of the holder arm 8a that is a movable arm may be formed on the reflecting surface as the detected portion.
[0020]
By changing the shape of the nail supply part 10 and the holder arm 8a, it can be used as a windmill mounting machine.
