BACKGROUND OF THE INVENTION
The present invention relates to a classification processing apparatus that classifies slips and the like by type.
[0002]
[Prior art]
Conventionally, in the business of handling a large amount of slips such as utility bills and bill exchanges, when sorting individual slips by type, shelves installed around the work desk have multiple classification storage spaces by partition plates The slip is manually stored in the classified storage space. That is, when a classification code is input from the input terminal device provided on the desk, a lamp for indicating the corresponding storage space is turned on, and the slip is manually inserted into the classification storage space as a mark. It was.
In addition, there is known an apparatus that, when classified and inputted as an automated product, conveys a slip to the position of the corresponding classified storage space and automatically stores it in the space.
[0003]
[Problems to be solved by the invention]
However, since the former is based on the premise of manual work, the work efficiency is low, and the automatic classification processing apparatus having a slip conveyance mechanism requires a conveyance mechanism and is therefore large. In addition, there are drawbacks such as paper jams easily occurring in the conveyance path when conveying various sizes and thicknesses of slips.
Therefore, when the type is specified when storing an article such as a slip, the present applicant rotates the storage unit classified by classification, detects the storage space position corresponding to the specified classification, and uses it as a slot. A corresponding technology (Japanese Patent Application No. 7-109187: name of invention “classification processing device”) has been proposed.
In this classification processing apparatus, a plurality of classified storage spaces are provided in the rotatable classified storage section, and the storage space corresponding to this type can be positioned at the article input port simply by specifying the type of the article. In addition, automatic sorting is possible, and a conveyance path is not required, so that a reduction in size and weight can be realized, and problems such as paper jams can be effectively solved. As a result, it has become possible to provide a classification processing apparatus that is suitable for recent office environments and is excellent in speediness, accuracy, operability, and the like.
[0004]
The object of the present invention is to improve the classification processing apparatus previously proposed by the applicant from the viewpoint of the electric system in consideration of the actual situation of actual sorting work, etc., and improve accuracy, operability, safety, durability, etc. It is to be able to further improve. That is, for example, in a voucher sorting operation that sorts documents such as document exchanges, bill exchanges, and utility bills by type at a bank, even if a skilled operator specifies the type of the voucher, the type may be mistakenly specified. In many cases, if the type is specified incorrectly, the slip cannot be accurately classified. On the other hand, even for a slip of the same type as the previous slip, specifying the type every time a slip is inserted has a problem in terms of operability.
The object of the present invention is to eliminate the need for a complicated operation for searching for an article that has been stored in another category by incorrectly specifying the type of the article, as well as previously stored articles. When an article of the same type is put in, the operability can be greatly improved such that it is not necessary to designate the type each time.
[0006]
[Means for Solving the Problems]
This invention has a classified storage section having a plurality of classification spaces for classifying a plurality of types of articles by type, and corresponds to the specified type when the type of the article is specified at the time of storing the article. A classification-specific processing device that detects a classification storage space to be driven and drives the classification-specific storage unit until the detected classification storage space corresponds to an article insertion port provided at a predetermined position. Each time the type is specified at the time of storage, a history storage means for storing the specified classification as history information, and each time a predetermined operation is performed, the contents of the history storage means are stored in accordance with a last-in first-out method. Until the reading means that reads back one by one and the classification storage space specified by the history information read by the reading means correspond to the article take-out port provided at a predetermined position Characterized by comprising a drive control means for driving the serial classification storage unit.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to FIGS.
FIG. 1 is an external perspective view showing a classification processing apparatus that classifies bills such as utility charges and taxes according to type.
The classification processing device 1 is entirely formed in a desk shape, and a keyboard 2 and a display device 3 are placed on one side of the top plate. Here, the keyboard 2 and the display device 3 are connected to the classification processing device 1 by cable, and the keyboard 2 is used for inputting a classification code indicating the type of slip and various commands. When the classification code is input, the classification processing device 1 causes the display device 3 to display and output the corresponding slip name. The display device 3 has a transparent touch panel laminated on a liquid crystal display screen, and also has a function as a touch input device for assisting the keyboard 2. It should be noted that each component (such as slip entry / exit) of the classification processing apparatus 1 shown in FIG. 1 will be described in detail later.
[0011]
FIG. 2 conceptually shows the main structure in the classification processing apparatus 1, (A) is a schematic cross-sectional view, and (B) is a schematic vertical cross-sectional view.
A classification box 5 is rotatably supported on the rotary shaft 4 in the top plate portion of the classification processing apparatus 1. The classification box 5 is entirely formed in a bottomed cylindrical shape, and a plurality of (in this example, 64) classification storage spaces 7 are formed inside by a plurality of partition plates 6 arranged radially. Has been. This classification storage space 7 stores the slips classified by type, and a positioning bar code (space number) 8 is added to the position corresponding to each classification storage space 7 on the outer peripheral surface of the classification box 5. Has been. Here, when a classification code for designating the type of a slip is input from the keyboard 2 at the time of storing or taking out the slip, the step motor 9 is driven and its rotation is transmitted to the classification box 5 via the belt 10. The classification box 5 is rotationally driven so as to be able to rotate forward and backward. At that time, the position mark sensor 11 reads the positioning barcode 8 attached to the outer peripheral surface of the classification box 5, and when the barcode 8 corresponding to the inputted classification code is read, the position mark sensor 11 The drive of the step motor 9 is controlled so that the classification box 5 stops. That is, the position mark sensor 11 is a bar code reader that detects the position of the classification storage space 7 assigned in advance corresponding to the input classification code, and the detected classification storage space 7 is the slip slot 12 (see FIG. The classification box 5 is driven to rotate until it comes to a position opposite to 1).
[0012]
On the other hand, a tension roller 13 that presses the belt 10 stretched between the step motor 9 and the classification box 5 is pressed. The tension roller 13 is slidably supported by the shaft, and detects the weight of the classification box 5 based on the magnitude of the repulsive force applied to the tension roller 13 via the belt 10 when the classification box 5 is driven to rotate or is stopped. FIG. 3 shows the configuration of this detection unit.
That is, as shown in FIG. 3, the tension roller 13 is rotatably attached to a support shaft 15 fixed to the base plate 14, and is pressed against the belt 10 so that the belt 10 is always pushed. The base plate 14 is always urged in one direction by a spring 16 and receives the elastic force to press the tension roller 13 against the belt 10. The base plate 14 is slidably inserted into the rail member 17 and is moved by a repulsive force applied to the tension roller 13 via the belt 10 when the classification box 5 is driven to rotate or stopped. This movement of the base plate 14 is detected by the microswitch 18. Here, the repulsive force applied to the tension roller 13 increases when the classification box 5 is started / stopped, but this pressure increases as the weight of the classification box 5 increases, and the amount of movement of the base plate 14 also increases accordingly. growing. Accordingly, it is possible to detect that the weight of the classification box 5 has increased to the set value by providing the microswitch 18 that is turned on at the position where the base plate 14 has moved when receiving a repulsive force of a predetermined magnitude. it can. The rotational speed of the step motor 9 is controlled according to the weight of the classification box 5 detected in this way (in other words, the slip amount).
[0013]
On the other hand, as shown in FIG. 2B, an electromagnetic brake 20 is provided below the step motor 9, and this electromagnetic brake 20 decelerates and stops the rotation of the step motor 9. A shutter 21 that automatically opens and closes the slip slot 12 is provided below the slip slot 12. The shutter 21 closes the slip slot 12 when the sorting box 5 is driven to rotate. The shutter 21 prevents the slip from being accidentally inserted and prevents danger. Further, the shutter 21 is opened. 1, the tip is bent obliquely downward as shown in FIG. 1, and serves to guide the slip when the slip is inserted. The front end of the shutter 21 extends horizontally by receiving the elastic force of the spring when the slip slot 12 is closed, but is bent against the elastic force when the slip slot 12 is open. It is done. The slip slot 12 is provided at a position in consideration of workability, and is formed somewhat larger than the size of one classification storage space 7.
[0014]
On the other hand, in FIG. 1, a slip outlet 22 is provided in the vicinity of the slip slot 12. The slip take-out port 22 is about two to three times larger than the slip put-in / out port 12 and is used when a bundle of slips classified and stored in the classification box 5 is taken out for each classification storage space 7. Is done. Here, the classification box 5 can be rotated manually, and a bundle of slips is taken out for each classification storage space 7 while rotating the classification box 5 directly. The slip slot 12 is automatically opened and closed by a shutter 21, while the slip outlet 22 is opened and closed by a manually openable lid member 23. The lid member 23 has a transparent window 24 formed in substantially the entire area thereof, so that the classification box 5 can be confirmed from the outside. The lid member 23 is provided with a rising type knob 25. The knob 25 is picked to open the lid member 23 in the direction of the arrow in the figure. When the knob 25 is raised, the motor is suddenly stopped.
That is, FIG. 4 shows a rising detection portion of the knob 25. When the knob 25 is raised in the direction of the arrow in the drawing, one end of the knob 25 rotates around the fulcrum, so that the microswitch 26 is turned on at that end. It is detected that the knob 25 has been raised, and the step motor 9 is stopped suddenly.
[0015]
FIG. 5 is a view showing a state when the classification storage space 7 corresponding to the designated classification is set at the slip slot 12. The partition plate 6 has a lower end portion that is detachably supported and has an upper end portion that is a free end. The partition plate 6 is freely inclined between 45 degrees to the left or 45 degrees to the vertical plane. In a state where no external force is applied, the partition plate 6 is inclined to the left or right by 45 degrees with respect to the vertical plane by its own weight. Then, the step motor 9 is decelerated in order to align the classification storage space 7 corresponding to the classification code input from the keyboard 2 with the position of the slip insertion slot 12, and the corresponding classification storage space 7 stops at the position of the slip insertion slot 12. Immediately before the operation, a solenoid (not shown) is driven to project the partition plate upright member 27 attached to the tip of the plunger. Thereby, this partition plate standing member 27 gradually raises the partition plate 6 to which the weight of the slip is not applied among the two partition plates 6 forming the classification storage space 7 as the classification box 5 rotates. When completely stopped, as shown in FIG. 5, the upper opening of the classified storage space 7 is widened to make it easier to insert the slip into the classified storage space 7.
In addition, in order to detect that the slip has passed through the slip slot 12, a plurality of light receiving elements 28 such as phototransistors are arranged in the vicinity of the slip slot 12 in the top plate portion of the classification processing apparatus 1. A plurality of light emitting elements 29 such as LEDs are disposed at the front end of the shutter 21, and the light receiving element 28 and the light emitting element 29 constitute a passage sensor 30.
[0016]
FIG. 6 is a diagram conceptually showing the configuration of a detection unit that detects whether a slip is left in each classification storage space 7 of the classification box 5. A light emitting unit 31 and a light receiving unit 32 are arranged opposite to each other above and below the classification box 5, and the light emitting unit 31 and the light receiving unit 32 are fixed so that their positions do not change even when the classification box 5 rotates. The light emitting unit 31 is provided with three light emitting elements 33 arranged in parallel at predetermined intervals, and the light receiving unit 32 is provided with three light receiving elements 34 corresponding to the light emitting elements 33. Each partition plate 6 has two light passage holes 35 as shown in FIG. 6A, and light from the light emitting unit 31 irradiated from the lower side of the classification box 5 is a light passage hole. The presence / absence of the remaining light is detected based on whether or not the light receiving unit 32 has been reached via 35. The two light passage holes 35 are formed in each partition plate 6 because the two partition plates 6 forming the classification storage space 7 are inclined at an angle of 45 degrees as shown in FIG. This is because light is allowed to pass therethrough.
[0017]
FIG. 7 is a block diagram showing the system configuration of the classified processing apparatus 1. The CPU 41 controls the overall operation of the classified processing apparatus 1 according to various programs in the internal storage device 42. The internal storage device 42 includes a RAM, a cache memory, a ROM, and the like, and programs and data called from the external storage device 43 are loaded into the internal storage device 42. The external storage device 43 is composed of a magnetic / optical storage medium or a semiconductor memory, and may be a memory card, a floppy disk, an expansion board, or the like that is detachably mounted. The program and data transmitted from the device may be received and stored.
[0018]
The internal storage device 42 is provided with a slip history memory 44, an allocation pointer 45, a space number allocation memory 46, a speed flag register 47, a slip type table 48, a motor control table 49, a sudden brake table 50, and the like. As shown in FIG. 8, the slip history memory 44 is a memory that stores and holds classification codes as history information in the order of input every time a classification code is input from the keyboard 2 when the slip is stored. The allocation pointer 45 is a pointer for accessing the contents of the space number allocation memory 46.
As shown in FIG. 9, the space number allocation memory 46 associates a barcode (space number) associated with each classification storage space 7 of the classification box 5 with a classification code. The order is set as shown. That is, the classification box 5 has 64 classification storage spaces 7 formed by the partition plates 6 arranged in a radial pattern, and when a predetermined space is set to “1” in the predetermined classification storage space 7, this classification A space number “2” is set in the classified storage space 7 in a position opposite to the storage space 7. Then, a space number “3” is set in the classified storage space 7 at a position of 90 degrees with respect to the classified storage space 7 with the space number “2”, and is opposed to the classified storage space 7 with the space number “3”. A space number “4” is set in the classified storage space 7 at the position “1”. Then, the space number “5” is set in the classified storage space 7 located between the space numbers “1” and “3”, and the classified storage space 7 located between the space numbers “2” and “3”. Set the space number “6” to. In this way, space numbers up to “64” are set. Therefore, the space numbers in the space number allocation memory 46 shown in FIG. 9 are arranged as shown in FIG.
[0019]
Here, when the classification code is input from the keyboard 2, the CPU 41 refers to the slip type table 48, converts it into the corresponding slip name, displays it on the display device 3, and refers to the space number assignment memory 46. Are converted into space numbers for designating the corresponding classified storage space 7. At that time, the CPU 41 refers to the space number allocation memory 46 to determine whether or not the input classification code is already associated with any of the classification storage spaces 7, and a new classification that is not associated with the classification code. If so, a classification allocation process is performed in which the classification code is set in the space number allocation memory 46 in association with the predetermined classification storage space 7.
[0020]
Further, when rotating the step motor 9, the CPU 41 operates the shutter driving unit 51 to close the shutter 21, and then gives a start command to the motor control unit 52 to rotate the step motor 9. Here, while the step motor 9 is rotating, the sensor unit 53 detects various states, and the detection signal is taken into the CPU 41 via the sensor control unit 54. As shown in FIG. 11, the sensor unit 53 includes a sheet presence sensor 55, a load detection sensor 56, and an opening operation detection sensor 57 in addition to the position mark sensor 11 and the passage sensor 30. Each time the barcode is read from the outer peripheral surface of the CPU 41, the CPU 41 refers to the space number allocation memory 46 and detects that the classification storage space 7 corresponding to the inputted classification code is set at the position of the slip slot 12. The step motor 9 is stopped and a shutter opening signal is given to the shutter drive unit 51. The CPU 41 gives a shutter closing signal to the shutter driving unit 51 when the passage sensor 30 detects the paper loading.
[0021]
The load detection sensor 56 detects the weight (total amount of slip) of the classification box 5 by the pressure applied to the tension roller 13, and has a configuration as shown in FIG. When a detection signal corresponding to the weight of the classification box 5 is input from the load detection sensor 56, the CPU 41 refers to the motor control table 49, controls the rotational speed of the step motor 9, and sets a flag indicating the speed at that time. Set in the flag register 47.
The opening motion detection sensor 57 detects that the knob 25 of the lid member 23 is raised during the rotation of the step motor 9, and has a configuration as shown in FIG. When the detection signal is input as a sudden brake signal from the opening operation detection sensor 57, the CPU 41 refers to the sudden brake table 50 and suddenly stops the step motor 9.
The sheet presence / absence sensor 55 detects whether or not a slip is left in each classification storage space 7 constituting the classification box 5, and has a configuration as shown in FIG. The CPU 41 notifies the remaining of the slip by a message display according to the detection signal from the paper presence sensor 55.
The classification processing device 1 is connected to a host computer or a printer device via an external interface 58.
[0022]
Next, the operation of this classification processing apparatus will be described.
FIG. 12 is a general flowchart showing the overall operation, which starts when the power is turned on.
First, when the power is turned on, the CPU 41 clears the contents of the slip history memory 44 and the space number allocation memory 46, and initializes various pointers (step A1). In this case, the space number allocation memory 46 stores the classification code in association with the space number as shown in FIG. 9, but each classification code is cleared by this initialization process. In addition, “0” is set as an initial value in an allocation pointer 45 that designates the contents of the space number allocation memory 46. A high speed flag indicating that the step motor 9 is rotated at a high speed is set as an initial value in the speed flag register 47. Next, it is detected whether or not there is a slip left in each classification storage space 7 in the classification box 5, and if there is, a left-out process for informing that is performed (step A2).
[0023]
FIG. 13 is a flowchart showing this leftover process. First, when the leftover detection key is operated (step B1), the CPU 41 drives the step motor 9 to rotate the classification box 5 once (step B2). Here, it is checked whether or not the sheet presence sensor 55 is turned on while the classification box 5 is rotated once (step B3). When the classification box 5 is turned on, a slip remains in any of the classification storage spaces 7, so that A message to that effect is notified (step B4). As a result, the operator takes out the slip from the classification box 5. At this time, since the rotation of the classification box 5 is stopped, the slip outlet 22 is opened by raising the knob 25 of the lid member 23 and opening the lid member 23. The voucher in the classification box 5 can be taken out. The remaining notification is performed until the execution key is operated (step B5), and when the execution key is operated, the process proceeds to step A3 in FIG.
[0024]
Here, when a classification code indicating the type of the slip is input from the keyboard 2 when the slip is stored (step A3), the slip name corresponding to the classification code is searched from the slip type table 48 (step A4) and input. The slip name is displayed and output in association with the classified code (step A5). Here, when the operator confirms the display contents and operates the execution key (step A6), the inputted classification code is set in the slip history memory 44 (step A7). Then, the process moves to the classification assignment process (step A8).
[0025]
FIG. 14 is a flowchart showing the classification assignment process.
First, the CPU 41 searches the space number assignment memory 46 based on the inputted classification code (step C1) and checks whether there is a corresponding classification code (step C2). That is, it is determined whether or not a classification code indicating the type of the slip is assigned to any space number when the slip is stored. Now, when the power is turned on, all the classification codes in the space number assignment memory 46 are all stored. Since it is cleared, it is determined that a new classification code not assigned to any space number is input. Then, the process proceeds to step C3, where it is checked whether the value of the allocation pointer 45 is less than “64”. That is, it is checked whether or not a classification code has already been allocated to all 64 classification storage spaces 7 provided in the space number allocation memory 46.
[0026]
Here, if the value of the allocation pointer 45 is “64” or more, a full state notification indicating that allocation is impossible is performed (step C8). If it is “64” or less, the value of the allocation pointer 45 is “1”. Are added (step C4). Here, since “0” is set as the initial value in the allocation pointer 45 when the power is turned on, the value is updated to “1”. Then, the space number corresponding to the value of the allocation pointer 45 is searched from the space number allocation memory 46, and the input classification code is set in the space number allocation memory 46 in association with the space number (step C5). Then, the space number corresponding to the value of the allocation pointer 45 is temporarily stored as information indicating the storage target (step C6). Such an operation is executed every time a classification code that is not already assigned to the space number is input. As a result, the input classification codes are assigned in the order shown in FIG.
On the other hand, when a classification code already assigned to the space number is input (step C2), the space number corresponding to the classification code is searched from the space number assignment memory 46, and this space number indicates the object to be stored. It is temporarily stored as information (step C7).
[0027]
When the classification assignment process is performed in this way, the process proceeds to step A9 in FIG. 12, and the slip classification process is performed.
FIG. 15 is a flowchart showing the slip classification process.
First, the CPU 41 gives a drive command to the motor control unit 52 and drives the step motor 9 to rotate the classification box 5 (step D1). Then, the CPU 41 refers to the speed flag register 47, the motor control table 49, etc., and controls the rotation speed of the step motor 9 (step D2). This motor speed control process is executed according to the flowchart shown in FIG.
[0028]
First, the CPU 41 refers to the speed flag register 47 to check whether the high speed flag is set (step E1) or whether the medium speed flag is set (step E2), and sets the high speed flag, medium speed flag, and low speed flag. In response, the motor control table 49 corresponding to the selected motor control table 49 is selected (steps E3, E4, E5). Here, FIG. 18 shows how the rotational speed of the motor is controlled according to the contents of the motor control table 49. The motor control table 49 is provided with a high-speed table, a medium-speed table, and a low-speed table. The rotational speed of the motor is controlled on the basis of the acceleration coefficient corresponding to the acceleration curve and the deceleration coefficient corresponding to the deceleration curve as shown in FIG. In this case, the acceleration curve is displaced from the peak point to the deceleration curve.
[0029]
That is, the step motor 9 is accelerated along the acceleration curve in accordance with the description content of the selected motor control table 49 (steps E6, E7, E8). When the step motor 9 is driven at high speed or medium speed, it is checked whether an ON signal is input from the load detection sensor 56 (steps E9 and E11). Here, if the load detection sensor 56 is not turned on, it is checked whether a sudden brake signal is input from the opening operation detection sensor 57 in any of high speed, medium speed, and low speed driving (steps E13, E14, E15). . If no sudden brake signal is input, the step motor 9 is decelerated according to the deceleration curve when the peak point of the acceleration curve is reached (steps E16, E17, E18). Even during deceleration, it is checked whether or not there is a sudden brake signal from the opening operation detection sensor 57 (steps E19, E20, E21). If not, an on signal is output from the load detection sensor 56 in the case of high speed or medium speed drive. It is checked whether it has been input (steps E22 and E23).
[0030]
In this way, when the step motor 9 is driven at high speed according to the high speed table, if the load detection sensor 56 is turned on during either acceleration / deceleration of the motor, the content of the speed flag register 47 is changed from the high speed flag to the medium speed. The flag is rewritten (steps E10 and E24). Similarly, when driving at medium speed according to the medium speed table and the load detection sensor 56 is turned on during motor acceleration / deceleration, the contents of the speed flag register 47 are changed from the medium speed flag to the low speed flag. It is rewritten (steps E12 and E25). That is, as shown in FIG. 3, the pressure applied to the tension roller 13 increases at the start / stop of the classification box 5, but this pressure increases as the weight of the classification box 5 increases, and the amount of movement of the base plate 14 increases. The load detection sensor 56 detects the weight of the classification box 5, in other words, the slip storage amount. If the micro switch 18 is turned on (load) When the detection sensor 56 is turned on), the rotational speed of the motor is reduced by one step and controlled from high speed to medium speed or from medium speed to low speed.
[0031]
On the other hand, if the sudden braking signal is input from the opening motion detection sensor 57 during both acceleration / deceleration of the motor (steps E13 to E15, E19 to E21), the CPU 41 proceeds to the sudden braking process of FIG. The step motor 9 is suddenly stopped with reference to the brake table 50. FIG. 19 is a diagram for explaining the sudden brake table 50. The sudden brake table 50 suddenly stops the motor along a limit deceleration curve at which the step motor 9 does not step out. Here, as shown in FIG. 4, when the knob 25 is raised to open the lid member 23 during the rotation of the motor, the microswitch 26 is turned on and a sudden brake signal is output. When the power is turned off simultaneously with the input of, the step motor 9 continues to rotate due to the inertia of the classification box 5 and does not stop for a while. FIG. 20A shows this state, and the curve shown by the solid line shows a state where it does not stop immediately due to the inertial force. On the other hand, if the power is turned off after the step motor 9 is suddenly stopped with reference to the sudden brake table 50, the motor can be stopped immediately. FIG. 20 (B) shows the situation in this case. If the drive frequency when the knob 25 is raised is fn, a sudden deceleration curve is formed from this point according to the contents of the sudden brake table 50, and the drive frequency fn. To f1 suddenly. Here, as shown in the flowchart of FIG. 17, sudden deceleration control is performed with reference to the sudden brake table 50 (step E26), and when the step motor 9 is completely stopped (step E27), the drive system power supply is turned off. In this way (step E28), program runaway or the like is prevented.
[0032]
When the motor speed control process is completed in this way, the process proceeds to step D3 in FIG. 15 and proceeds to the position mark reading process. That is, while the classification box 5 is rotating, the position mark sensor 11 reads the positioning bar code 8 attached to the outer peripheral surface, and determines whether the read result matches the space number corresponding to the inputted classification code. (Step D4), if they do not match, the process returns to Step D2 and the motor continues to rotate. When coincidence is detected, the electromagnetic brake 20 is turned on (step D5), and the solenoid is turned on to cause the partition plate upright member 27 to enter the classification box 5 (step D6). In this case, the classification box 5 is slightly rotated, and the partition plate 6 is gradually raised by the partition plate standing member 27 as the rotation is performed (see FIG. 5).
Then, the CPU 41 turns off the step motor 9 (step D7), opens the shutter 21 (step D8), and further drives the passage sensor 30 (step D9). If the slip is not inserted (step D10), a message indicating that the slip should be inserted is displayed (step E11), and the process returns to step D9 until it is inserted, waiting for insertion. Now, when the slip is inserted, the shutter 21 is closed (step D12), the electromagnetic brake 20 is turned off (step D13), and the solenoid is further turned off to retract the partition plate upright member 27 from the classification box 5. (Step D14).
[0033]
When the slip classification process is completed, the process returns to step A3 in FIG. 12 and waits for key input. Thereafter, the above-described operation (steps A4 to A9) is repeated every time a classification code is input. Thus, the slips can be classified and stored in the classification box 5 simply by inserting the slips from the slip slot 12. Even when a slip is taken out from the classification box 5, if the classification code is input, the corresponding classification storage space 7 is positioned at the slip slot 12, so that the bundle of the classified and stored slips is classified into the classification. It can be taken out from the storage space 7. On the other hand, when the slip is noticed and the classification code input earlier is noticed, the return key is operated (step A10). Then, the storage operation return process is performed (step A11).
[0034]
FIG. 21 is a flowchart showing the storage operation return processing.
First, the current position in the slip history memory 44 is returned to the previous position (step F1). That is, as described above, the slip history memory 44 sequentially stores the classification codes as history information in accordance with the input order every time a classification code is input when the slip is stored, and the current position (lastly the classification code is input). (Position F) is designated (step F1), and the classification code corresponding to the designated position is read from the slip history memory 44 (step F2). Then, the space number corresponding to the classification code is read from the space number allocation memory 46 (step F3), and when the classification storage space 7 corresponding to the number is positioned at the slip slot 12, the classification box 5 is rotated. The classification box 5 is stopped (step F4). Then, the slip name is displayed and output together with the classification code (step F5).
[0035]
Here, the operator confirms the display contents, and if there is no input mistake, further operates the return key (step F6). Then, the process returns to Step F1, is returned to the previous position, and the above-described operation is repeated. In this way, the corresponding classified storage space 7 is sequentially set at the position of the slip slot 12 while going back one by one according to the storage history. Here, if the display content is an input error, the execution key is operated (step F6). Then, the shutter 21 is opened (step F7). When the end key is operated, the end notification is made and the shutter 21 is closed (step F8). Then, the process returns to step A3 in FIG.
[0036]
As described above, according to this classification processing apparatus, when the classification code of the slip is input and designated when the slip is stored, if the specified classification is not already assigned to the classification storage space 7, Since the unused classification storage space 7 is determined according to the order shown in FIG. 10 and the designated classification is assigned to this classification storage space 7, the slips can be stored in a balanced manner throughout the classification box 5. become. For example, what sorts of slips are classified and stored in sorting operations such as banks generally differ greatly from day to day, but which slips are stored in each sort storage space 7 is fixedly determined in advance. If this is done, the storage state of the slip becomes uneven, and the load on the rotating mechanism becomes large and may cause a failure. The durability of the rotation mechanism, which is the main part of the classification processing apparatus 1, can be greatly improved.
[0037]
In addition, if the classification code is input and specified incorrectly when storing the slip, there is a basic problem that the slip cannot be stored correctly. In this case, in this embodiment, By simply operating the return key, the previously specified classification code is read back from the slip history memory 44, and the classification storage space 7 corresponding to this classification is automatically set at the position of the slip slot 12; A slip slipped in by mistake can be easily found, and workability can be greatly improved. The return key is not limited to the case where the classification code input specification is wrong. For example, when entering a slip of the same classification as the classification specified last time or a plurality of times before, the return key can be used without inputting the classification code. It is only necessary to operate, and the operability can be greatly improved.
[0038]
Further, a tension roller 13 for pushing the belt 10 stretched between the step motor 9 and the classification box 5 is provided, and the pressure applied to the tension roller 13 at the start / stop of the classification box 5 is detected and the classification box 5 Since the weight is detected and the rotation speed of the step motor 9 is controlled in accordance with the weight, the rotation can be controlled before the step motor 9 steps out, and the classification box 5 is always driven normally. It becomes possible to make it.
In addition, since the presence / absence sensor 55 detects whether a slip remains in the classification box 5 when the power is turned on, for example, if there is a slip left at the end of the last sorting job, It can be recovered at the start.
Furthermore, if the knob 25 of the lid member 23 is raised while the step motor 9 is rotating, that is, the step motor 9 is stopped suddenly before the lid member 23 is opened, danger can be avoided in advance. Is possible. In this case, since the drive power supply is turned off, malfunction due to program runaway can be prevented.
[0039]
In addition, this classification | category processing apparatus is not restricted to embodiment mentioned above, The following may be sufficient as the modification application example.
The allocation of space numbers is not limited to the order shown in FIG. Moreover, although the partition plate 6 for forming the classification storage space 7 in the classification box 5 is removable, the classification storage space 7 may be expanded by removing any partition plate 6. . In this case, a space number assigned in advance to each classified storage space 7 before expansion may be handled as the same space number.
When a classification code is input when the slip is stored, it is stored in the slip history memory 44. However, when the passage sensor 30 detects that the slip is put into the classification box 5, the classification code is stored. May be stored in the slip history memory 44.
The leftover process is not limited to when the power is turned on, but may be performed at an arbitrary timing when a predetermined key operation is performed, or may be automatically performed at the end of the job. Furthermore, in the leftover process, a space position where a slip remains may be detected and the space may be automatically set at the slip slot 12 position. Further, the sheet presence / absence sensor 55 for detecting the leftover is not limited to the transmission type, but may be a reflection type sensor.
The load detection sensor 56 that detects the weight of the classification box 5 detects whether the weight of the classification box 5 has reached a predetermined value by turning on / off the micro switch 18 or is a potentio instead of the micro switch 18. If the amount of movement corresponding to the repulsive force is detected step by step using a meter, finer motor control becomes possible.
[0040]
【The invention's effect】
According to the present invention, every time the type is specified at the time of storing the article, the specified type is stored as history information, and according to the history information, the classified storage unit is driven retroactively. If the item is stored in a different category by specifying the wrong type, there is no need for complicated work to find it, and the same type of item as the previously stored item is used. In this case, the operability can be greatly improved by not having to specify the type each time.
