Description

  In the present invention, when a paper sheet processing system for processing paper sheets such as securities is composed of a plurality of devices (hereinafter referred to as modules) that can be divided, it accompanies jam processing that occurs in the module. The present invention relates to a paper sheet processing system that performs initialization efficiently.

  In a paper sheet processing system for processing paper sheets such as securities, a paper sheet processing apparatus as a pre-processing apparatus and a paper that is sorted and bound by the paper sheet processing apparatus as a post-processing apparatus Some have a packaging device for packaging leaf bundles.

  The paper sheet processing device conveys the supplied paper sheets, and the paper sheet discriminating apparatus passes the paper sheets to the correct bill (paper sheets that can be circulated as a genuine note) and the non-performing ticket (recirculated as a genuine note). Non-permitted paper) and rejected tickets (paper sheets other than regular or non-performing tickets), and categorized and accumulated based on the discrimination results, and every time a predetermined number (for example, 100) is reached This is a device for binding (sealing) with a thermal adhesive paper strip.

  In order to process the so-called sorting process described above at a high speed, this type of paper sheet processing apparatus has come to use a large paper sheet stacking apparatus including a plurality of stacking and sealing apparatuses. In addition, this type of large-scale apparatus is often composed of a plurality of modules that can be divided from the viewpoint of manufacturability or maintainability.

  In order to cope with this, packaging apparatuses as post-processing apparatuses have also become large, and are similarly often divided into a plurality of apparatuses (hereinafter referred to as modules). For example, each module is arranged as modules MA, MB, MC,.

  The module MA arranged on the upstream side of the transport is a stacking device that receives a bundle of 100 sheets discharged from the paper sheet processing apparatus and stacks 10 sheets (for each category) in a standing state according to the classification of the paper sheets, for example. is there.

  The module MB is a bundling device that forms a bundle of 1000 sheets by further bundling 10 bundles of 100 sheets collected from the module MA for each category with a bundling material.

  The module MC is a packaging device that shrink-packs a bundle of 1000 sheets formed by the module MB.

  As described above, in the paper sheet processing apparatus, the paper sheets taken out at a predetermined interval are sorted and accumulated by the accumulating device, and each 100 sheets are sealed (bundled) by the sealing apparatus. The bundle is discharged to a conveyor disposed at the lower part of each module, and is delivered to the above-described packaging device as a post-processing device.

  Here, when a jam of 100 bundles transported in the packaging apparatus occurs, an operation (or maintenance staff) removes the jammed tickets (here, 100 bundles).

At this time, a part or all of the exterior doors of the device are opened by the operator for the clogging ticket removal operation.

  The packaging device has a mechanism that can detect the opening and closing of the exterior door to ensure the safety of the worker while the exterior door is open. Stop the operation of the equipment in the device. While the exterior door was open, power to the equipment in the packaging device was shut off, and after the exterior door was closed, initialization was performed by the operator at an arbitrary timing. It is well known that power is shut off when the door is opened with regard to the safety of the exterior door and the processing apparatus (see, for example, Patent Document 1).

JP 2008-192941 A (page 6-7, FIG. 5)

  However, the packaging device described above has a structure in which modules divided for each function are combined, and one or two exterior doors may be arranged for each device. While any one of the doors is in an open state, it is necessary to cut off the power to all devices that can be touched by a human hand from the door to ensure safety.

  Once the exterior door is opened, the module needs to be initialized by the operator's hand after the door is closed again. This initialization operation is performed only for the module whose power is cut off. At this time, regardless of whether the inside of the target module is jammed or not, all the sheet bundles are removed from the inside of the module. There must be.

  In other words, when performing a jammed ticket removal operation, the operator opens only the exterior door of the module corresponding to the location where the ticket jam occurs, removes all the tickets including the jammed ticket from the inside of the module, and initializes the device. Just do it.

  However, if a part of the normal ticket jam occurs in the transport part that straddles between modules, in this case, for safety reasons, both the exterior doors of the two modules are open. And the clogging ticket removal work must be done. As a result, since it is necessary to remove not only the jammed tickets but all the tickets in both modules, there is a problem that the work procedure of the operator and the processing time for initialization by the apparatus increase.

  The present invention has been made in order to solve the above-described problem. An internal door is disposed on a partition plate separating one module from the other module, the front door of one module is opened, and one of the modules is opened. When the internal door is opened from the module side, the power of the device within the operable range is stopped. When the operator removes the remaining sheet bundle and closes the inner door and the front door, all the modules in the two modules are initialized by opening one module side and the inner door and initializing the device within the operable range. It is an object of the present invention to provide a paper sheet processing apparatus that can shorten the initialization processing time and consequently improve the processing efficiency as compared with the case where the initialization processing is performed.

In order to achieve the above object, a paper sheet processing system according to claim 1 of the present invention is a paper sheet processing system composed of a plurality of modules, and is an exterior door of the first module on the upstream side in the transport direction. The exterior door of the second module downstream in the transport direction continuous to the first module, the exterior door detection device for detecting the opening of the exterior door of the first module and the exterior door of the second module, A partition plate for partitioning between one module and the second module, a maintenance hole penetrating the partition plate, an internal door that can be opened and closed to open and close the maintenance hole, and an interior that detects the opening of the internal door A door detecting device; a shut-off means for shutting off the power supply in the module; and a control means for controlling the shut-off means, wherein the control means has a fault in the first module or the second module. When the open state of the exterior door and interior door module in which the fault has occurred is detected by Tsu by the exterior door sensing apparatus and the internal door detection device, other modules operable range of the internal door The power supply is shut off by the shut-off means.

  In a paper sheet processing system composed of multiple modules, if a failure occurs in the device and it is necessary to remove a bundle of residual paper, etc., the front door adjacent to the failure can be opened by opening the module front door. Since it is possible to remove the remaining sheet bundle without opening the door, the initialization time can be shortened. In addition, the reduction in the initialization time can improve the processing efficiency of the apparatus.

  The packaging device of the present embodiment is configured by connecting four modules. In this embodiment, a maintenance hole is provided in the partition plate between the lower stacking portion and the upper transport portion constituting the module MA, which is a module upstream in the transport direction, and an internal door that can be opened and closed from the maintenance hole. When the opening of the internal door is detected, and the internal door is opened, the operation of the device within the range that can be operated from the internal door is stopped. Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 shows a paper sheet processing system according to an embodiment of the present invention. FIG. 2 is an external view of the packaging device shown in FIG. FIG. 3 is a front external view of the stacker unit 100 including the take-in / stack unit shown in FIG. FIG. 4 is a diagram for explaining the flow of processing of a sheet bundle in the sheet processing system. Hereinafter, description will be given with reference to these drawings.

  The paper sheet processing system according to this embodiment includes a paper sheet processing apparatus 1 as a pre-processing apparatus and a packaging apparatus 2 as a post-processing apparatus.

  The paper sheet processing apparatus 1 is a device for processing the paper sheet bundle SA supplied in a batch, and the paper sheet bundle SB supplied to the supply unit 12 is sequentially taken out from the uppermost paper sheet P. To the transport path 13. The paper sheet P supplied to the transport path 13 is checked for authenticity (whether it is a genuine ticket or a fake ticket) or damage (positive or reusable) by the paper sheet discriminating device 23 for each sheet. Ticket or non-recyclable ticket).

  Based on the determination result, the correct bill is conveyed to the stacking / sealing device 35, and the damaged ticket is transported to the stacking / sealing device 36. The stacking / sealing devices 35 and 36 are disposed at the end of the transport path, and stack the paper sheets P discharged from the end of the transport path 13 by the impeller stacking device. Each time the number of accumulated paper sheets P reaches 100, they are bound by a heat-bonding paper band (binding material) K by a sealing device (also called a binding device) disposed at the lower part of the impeller stacking device. A bundle of 100 sheets H is formed.

  This bundling is performed for each of the correct bills and non-performing bills as a category, and is usually performed by changing the color of the paper strip in order to distinguish the correct bills from the non-slip bills. This is so that it is possible to distinguish between a genuine ticket and a non-paid ticket simply by looking at the paper strip. In addition, although the said category is used also when dividing into not only a right ticket and a non-defective ticket but into the kind of paper sheets, a present Example demonstrates the case where it classifies into the said right ticket and a non-defective ticket.

  The 100-sheet bundle H formed in this manner is conveyed in the direction of the arrow A by the conveyor 10 disposed below the stacking and sealing devices 35 and 36, and the lift device 50 disposed at the end of the conveyor 10. To be handed over.

  The lift device 50 receives the 100-sheet bundle H received from the conveyor 10 and places it on the lifter 51 to lift it. The 100-sheet bundle H that has reached a predetermined position is pushed out by a pusher (not shown) and delivered to the lower receiving portion 115 of the stacker 100 (see FIG. 4A).

  FIG. 3 is a front external view of the stacker unit 100 including the receiving / stacking unit shown in FIG. The stacker unit 100 corresponds to the module MA of the packaging device 2, and includes a lower receiving unit 115, a lower stacking unit 110 (first module), an upper receiving unit 170, an upper stacking unit 171, and an upper transporting unit 160 (second module). And having a plurality of modules.

  The lower receiving portion 115 is a portion that receives the 100-sheet bundle H discharged from the paper sheet processing apparatus 1 during normal operation in a standing state.

  The lower stacking unit 110 (first module) stacks the 100-sheet bundle H received by the lower-stage receiving unit 115 in a standing state for each category, and further bundles when reaching a predetermined number (for example, 10) to bundle 1000 sheets It is a part to be transported to make it.

  When the stacker unit 100 is faulty and the upper-stage receiving unit 170 receives the 100-sheet bundle H by the lower-stage receiving unit 115 and cannot perform a predetermined process thereafter, the upper-sheet receiving unit 170 sends the 100-sheet bundle H sent out from the sheet processing apparatus 1. Is received by the upper receiving unit 170, and the received 100-sheet bundle is stored in the upper stacking unit 171. Since the upper stacking unit 171 is present, even when a failure occurs in the stacker unit 100, the processing can be performed without interruption. Since this function is not intended to be the gist of the present invention, detailed description thereof is omitted.

  The upper transport unit 160 (second module) is located downstream of the transport that is continuous with the lower stack unit 110 (first module) located upstream of the transport, and the 100-sheet bundle H received by the lower stack unit 110 reaches 10 pieces. This is a portion that is transported to the bundling device 200 for further bundling the sheet bundle SB.

  FIG. 4 is a diagram for explaining the flow of processing of the sheet bundle SB in the sheet processing system. As described above, the 100-sheet bundle H delivered to the lower-stage receiving unit 115 is sent out in the direction of the arrow B in the figure, and is categorized into a correct ticket or a damaged ticket by the category selection unit 120. The correct bill is further pushed out in the direction of the arrow Ea and accumulated in the stacking portion 130a in a standing state, and the damaged bill is sent out in the direction of the arrow D and converted backward and pushed out in the direction of the arrow Eb. Are accumulated in a standing state.

  The bundle of 100 sheets H accumulated in each of the stacking units 130a and 130b is counted, and when it reaches 10 each, it is pushed out by the direction changing unit 140a or 140b in the direction of the illustrated arrow Ga2 or Gb2 to the lifter 151 of the lift unit 150. Delivered.

  The lift unit 150 lifts the sheet bundle SB (10 100-sheet bundles H) placed on the lifter 151 in the direction of the arrow I in the drawing and delivers it to the upper transport unit 160. As a result, the 100-sheet bundle H taken into the lower stacking unit 115 is lifted and delivered to the upper transport unit 160 every time 10 sheets are stacked.

  The above-mentioned lifter 151 is used to lift the sheet bundle SB (10 100-sheet bundle H) in the lower stacking unit to the upper transport unit in order to further bind the lifted sheet bundle SB. Therefore, it is necessary to rotate the binding material along the outer periphery of the loaded sheet bundle SB, and a large space is required on the top, bottom, left and right of the sheet bundle SB. In order to create this space, the sheet bundle SB is lifted to a predetermined position.

  FIG. 5 is a diagram for explaining the open / close detection device 164 of the internal door 162 provided in the upper transport unit 160 shown in FIG. 3.

  The lower stacking unit 110 and the upper transporting unit 160 are partitioned by a partition plate 161c. However, the lower transporting unit 110 positioned upstream of the transport and the upper transporting unit 160 positioned downstream of the transport are connected by a lifter 151. The sheet bundle SB is transferred from the lower stacking unit 110 to the upper transport unit 160 by the lifter 151. Therefore, a through hole 165a through which the lifter 151 passes is provided. Further, a maintenance hole 165b is provided in the vicinity thereof. An internal door 162 that can be opened and closed from the upper transport section 160 side is disposed in the maintenance hole 165b. A bar 163 that can move integrally with the internal door 162 is attached to the internal door 162.

  When the internal door 162 closes the maintenance hole 165b, the bar 163 is inserted into the insertion port 165 of the internal door detection device 164 and is detected by the internal door detection device 164. In this state, when the internal door 162 is opened in the direction of the arrow J in the figure, the bar 163 is not detected by the internal door detection device 164, indicating that the internal door 162 is open or in an open state.

  In the internal door detection device 164, a projector and a light receiver are incorporated in the insertion port 165. When the bar 163 is inserted between these, the light projector and the light receiver are blocked, and the bar 163 is detected. This type of bar detection method is not limited to the transmission detection method using the above-described projector and light receiver, but may be a reflection type detection sensor that detects reflection from the bar, or a magnetic sensor type in which a permanent magnet is attached to the bar. Is possible.

  FIG. 6 is a diagram illustrating the configuration of the door detection device. The illustrated example shows the configuration of the exterior door detection device 113 of the lower stacking unit front door 112a as an exterior cover. The basic detection method and operation are the same as those of the internal door detection device 164 of the internal door 162 described above. The exterior cover has various door detection devices depending on the exterior shape and the opening / closing method. In either case, the bar (here, the bar 112c) detected on the door to be opened / closed (here, the lower stacking unit front door 112a) side. ) And a door detection device (in this case, the exterior door detection device 113) that detects the bar 112c when the door (lower stacking unit front door 112a) is closed is configured on the main body side. .

  For example, the lower stacking unit side cover 111a view of the stacker unit 100 shown in FIG. 3 can be opened in the illustrated arrow L direction, and the lower stacking unit 112a can be opened in the illustrated arrow M direction. These exterior cover door detection devices are as described above.

  In the stacker unit 100 configured as described above, for example, when a failure (jam) occurs in the transport of the stacking unit 130b of the 100-sheet bundle H on the category B side of the lower stacking unit 110, the failure is detected from the stacker unit 100. The paper sheet processing apparatus 1 is notified.

  The sheet processing apparatus 1 receives the failure information from the stacker unit 100, changes the supply destination of the 100-sheet bundle H from the lower receiving unit 115 to the upper receiving unit 170, and is processing in the sheet processing apparatus 1 The supply of the 100-sheet bundle H is continued.

  Further, the control unit 190 of the stacker unit 100 continues the processing on the category A side of the stacker unit 100 and stops the conveyance on the category B side where the failure has occurred. The sheet processing apparatus 1 displays the failure on the apparatus 1. In addition, the packaging device 2 displays this abnormality on the operation display unit 210 of the binding unit 200.

  An explanation will be given of a case where the operator confirms that the failure is the transfer on the category B side and opens the upper transfer section door 161a of the upper transfer section 160. The transport unit bar 161a can be opened by pulling the handle 161b in the direction of the arrow K in the drawing. A door detection device is also attached to the upper conveyance section door 161a, and the opening / closing of the door is detected.

  When the upper transport section door 161a is opened, the drive source disposed in the upper transport section door 161a is shut off, and the remaining sheet bundle can be removed. In this case, the sheet bundle SB remaining in the upper transport unit 160 can be removed. However, conventionally, the upper transport unit 160 and the lower stack unit 110 are partitioned by the partition plate 161c at the bottom, and it is impossible to access the lower stack unit 110 from within the upper transport unit 160. 100 bundles related to category B could not be taken out. In the present embodiment, the internal door 162 provided in the upper transport unit 160 can be opened. FIG. 5 shows a state in which the internal door 162 is opened in the direction of the arrow J shown in the figure.

  When the internal door 162 is opened, the internal door detection device 164 detects that the internal door 162 is open. By this detection, the control unit 190 stops the power within the range that the operator can operate from within the upper transport unit 160. In the present embodiment, during normal operation, the power for pushing and stacking the stack of 100 sheets into the category B stacking tray 131b, the power for driving the stacking tray 131b, and the sheet bundle SB from the stacking tray 131 are on the arrow Gb2 side. A plurality of power sources are used, such as power to push the lifter 151, power to push the sheet bundle SB into the back side in the lifter 151, power to drive the lifter 150, and the like.

When the above-mentioned failure occurs, even if the power is not stopped at that time, in order to ensure safety, if the internal door 162 is opened, the content of the failure Regardless of the power, the power within the operable range from the internal door 162 is stopped. The power source is provided by the main controller 190 shutting off an electromagnetic switch (not shown) under the following conditions (1) or (2).

(1) Power supply interruption to the lifter 150:
Power supply to the lifter 150 is performed via an electromagnetic switch, and the lower stacking unit front door 112a (first module exterior door) or the upper transport unit door 161a (second module exterior door) is in an open state. When detected, the power is shut off.

(2) Power interruption at the part touched by the operator when the internal door 162 is opened:
The upper transport unit door 161a is opened, the internal door 162 is opened, and power is supplied to the equipment of the lower stack unit 110 that can be touched by an operator via an electromagnetic switch, and the lower stack unit front door 112a is opened. When it is in a state, or when it is detected that the upper transport door 161a is open and the internal door 162 is also open, the power is cut off.

  The operator confirms that the power of the drive unit has stopped and removes the sheet bundle SB. In this example, since a failure has occurred on the category B side, the sheet bundle placed on the stacking tray 131b is removed.

  As described above, the operation of removing the remaining sheet bundle can remove the sheet bundle remaining in the lower stacking unit 110 by opening the inner door 162 of the upper transport unit 160 and putting a hand in the inner door 162. According to this method, since it is not necessary to open the lower stacking unit front door 112a to remove the sheet bundle remaining in the lower stacking unit 110, the portion where the power is stopped is limited, and the subsequent return time is shortened. be able to.

  In addition, when a failure occurs in the lifter 151 or the drive unit that raises the lifter 151, the control unit 190 cannot supply the sheet bundle SB from the stacking tray 131 a or 131 b to the lifter 151. Then, the driving of the stacking trays 131a and 131b is also stopped. In this case, it is necessary to remove not only the sheet bundles placed on the stacking trays 131a and 131b but also the sheet bundles placed on the lifter 151. Further, it may be necessary to remove the sheet bundle inside the upper transport unit 160.

  After the above-mentioned remaining sheet bundle is removed, the stopped power source is restored by pressing the reset button.

  When a failure occurs on the category B side described above, since the failure occurs not in the internal door 162 but in the lower stacking unit 110 after opening the upper transport unit door 161a, the lower stacking unit front cover 112a is attached. When opened, all the power sources of the lower stacking unit 110 and the upper transporting unit 160 constituting the stacker unit 100 are stopped, and after all the remaining paper sheet bundles are removed, all the power sources constituting the apparatus 100 are stopped. It goes without saying that since the device initialization work is performed, it takes more time than when the above-described internal door 162 is opened and the return process is performed.

  As described above, the range of the power source to be stopped and the range of the sheet bundle to be removed are different depending on the content of the fault, but when the fault occurs in the stacker unit 100, all the power sources of the stacker unit 100 are stopped, The stacker unit 100 can be returned without removing all the paper sheet bundles remaining inside. Hereinafter, a process when a failure occurs will be described.

  FIG. 7 is a flowchart for explaining processing when a failure (jam) occurs. In the present embodiment, the lower stacking unit 110 is provided with a plurality of exterior doors, and similarly, the upper transport unit 160 is also provided with a plurality of exterior doors. Since the door to be opened may differ depending on the degree of the failure, in this description, the lower stacking unit is referred to as a first module, and the upper transport unit is referred to as a second module.

  When a failure occurs in the first module or the second module (Y in S1 or Y in S2), the power of the drive unit related to the failure described later stops at that time.

  After the failure, when the first module door is detected (Y in S3), or when the second module door is detected and the internal door is closed (Y in S4, N in S5) Then, the power of the related conveying means is shut off (S6).

  On the other hand, when the door of the first module is not opened, but the door of the second module is opened and the internal door is opened (Y in S5), the range that can be operated from the internal door of the second module Is interrupted (S7).

  As a result of the processing in step S6 or S7, the safety of the corresponding portion is cut off, so that safety is secured. Therefore, the operator may remove the sheet bundle SB remaining due to the failure. Yes (S8).

  After step S8, initialization processing is performed from the operation display unit 210. By performing the initialization process, it is possible to recover the power cut off due to the occurrence of the above-mentioned failure and to make it possible to use it normally.

  Therefore, the contents of the initialization process may differ depending on the scope of the failure, but the description of the initialization process is omitted because the initialization process is not the gist of the present invention.

  In step S3 or S4, when the door closing of the first module and the door closing of the second module are detected, it indicates a state in which these doors are not opened although a failure has occurred. A loop is formed by shifting the processing to step S3. However, this processing is not necessarily performed, and when the processing shifts to the jam processing even though no failure has occurred, Alternatively, priority may be given to the conversion processing.

  FIG. 8 is an external view of the left side surface of the stacker unit shown in FIG. 3 and shows the discharge direction of the 1000-sheet bundle SC. The sheet bundle SB lifted by the lift unit 150 is aligned and compressed by the upper transport unit 160 to complete preparation before binding. The sheet bundle SB in this state is conveyed from the stacker unit left side cover 101 in the direction indicated by the arrow O1 and sent to the bundling unit 200 which is the next step.

  In the bundling unit 200, the paper sheet bundle SB sent out from the stacker unit 100 is bundled with the bundling materials C1 and C2 at a predetermined position to form a paper sheet bundle SC and discharged in the direction of the arrow O2. The figure shows a state in which the 1000-sheet bundle SC has been formed and released.

  According to the present invention described above, when an abnormality occurs, the front door opening and closing of the module can be minimized according to the abnormality location displayed on the operation display unit or the residual information of the paper sheet, and the residual The initialization time after the paper sheet take-out process can be shortened, thereby improving the processing efficiency of the paper sheet processing apparatus.
