Description

  The present invention relates to a paper sheet processing apparatus that processes paper sheets such as securities, and in particular, improved the safety of the stacking apparatus in which the stacking apparatus that stacks paper sheets can perform open pocket processing or cassette processing. The present invention relates to a paper sheet processing apparatus.

  A paper sheet processing apparatus that processes paper sheets such as securities, takes out the paper sheets one by one from the paper sheets supplied to the supply unit according to the processing unit, and conveys them one by one. The discriminating device discriminates the paper sheet, and the paper sheet is classified based on the discrimination result. The paper sheets sorted in this way are sorted into a ticket type, a damage or a rejected ticket, and then collected in a temporary stacker of the stacking device.

  There are an open pocket method, a cassette method, and a sealing method in the output form of the paper sheets accumulated in the temporary storage.

  The open pocket method is a method in which the device's business form is carried out in an open pocket business. When the number of sheets accumulated in the temporary storage reaches a predetermined number, the operator pulls it out and manually seals it. It is.

  The cassette system is a system in which the business form of the apparatus is performed in a cassette business. When a predetermined number of paper sheets are collected in the temporary stacker, the paper sheets are stored in a cassette disposed below the paper sheets. Automatically done by the method. This method has been used conventionally.

  The sealing method is automatically performed by the sealing device in such a manner that when a predetermined number (for example, 100 sheets) of paper sheets accumulated in the temporary stacker is reached, the sheets are bound by a binding material such as a paper band. This method has been used in the past. However, since the apparatus is complicated and expensive, it is often used for a designated ticket type in the paper to be processed.

  The above-mentioned open pocket business and cassette business are operation modes of the stacking device. When a plurality of stacking devices are provided, each of the stacking devices can be set and used as an open pocket business or a cassette business.

  Here, an example of a specific operation method of the open pocket business will be described below.

  First, when 100 sheets are stacked in the temporary stack (100 sheets), the sheet processing apparatus stops stacking in the temporary stack.

  Next, the operator opens (opens) the door of the temporary stacker, and pulls out the 100 sheets of paper collected in the temporary stacker in a rose state. This open pocket business is conventionally known (see, for example, Patent Document 1).

Next, the operator forms a bundle by winding a band on the extracted 100 sheets of paper (100 sheet winding method). Alternatively, the separated loose paper sheets are supplied again to the paper sheet processing apparatus and sealed (bundled) with the sealing apparatus to form a bundle.

In addition, a switch or button for starting or stopping the business of the paper sheet processing apparatus (device) 1 in the state set in this way is provided.

  After this setting, the operator sets the paper sheet P to be processed on the supply table 3. When the operation is started from the operation display unit 202 after the paper sheets are set, the paper sheets P are taken out one by one by the take-out roller (take-out means) 5 to the transport path (transport means) 11. The taken out paper sheet P is nipped and conveyed by an opposing belt.

  The supply unit 2 is provided with a supply table 3 so that a cassette 4 loaded with paper sheets P to be processed can be set on the supply table 3.

  The paper sheet P loaded in the cassette is taken out to the transport unit 10 by the take-out roller 5 when the backup plate disposed inside presses the paper sheet in the traveling direction.

  The transport unit 10 includes a transport roller (not shown) and a transport belt (not shown) wound around the transport roller, and the paper sheet P taken out by the take-out roller 5 is downstream from the top in the transport direction. Transport toward.

  An alignment unit 6, an inspection unit 20, and sorting devices G1 to G8, G12, and G13 are arranged on the conveyance path.

  The alignment unit 6 detects the transport state supplied on the transport path and corrects the transport state. The paper sheet P in a state corrected in this way is conveyed toward the inspection unit 20 arranged downstream of the alignment unit 6.

  The inspection unit 20 discriminates the authenticity, ticket type, transport direction, and correctness of the transported paper sheet P, and the main control unit 17 and transport the paper sheet information of the paper sheet P as the determination result. It transmits to the control part 16.

  The transport control unit 16 drives the sorting devices G1 to G13 based on the paper sheet information, and transports the paper sheet P to the final transport destination (stacking device or sealing device).

  The transport destination of the paper sheet P is determined based on the paper sheet information from the inspection unit 20 and the business content from the operation display unit 202. The paper sheet P is guided to the transport destination (the stacking unit 50 or the sealing unit 40) determined by the sorting device.

  In the stacking unit 50, six stacking devices including an impeller, a temporary stacker, and a storage (cassette) are arranged. Since the accumulation devices 57 to 62 are similarly configured, the accumulation device 57 will be described in detail below.

  The paper sheets P conveyed to the accumulation device 57 are separated from the conveyance path by the impeller 57a and accumulated in the temporary accumulation box 57b. When the number of sheets P accumulated in this way reaches a predetermined number, the subsequent processing differs in the open pocket business and the cassette business described later. The open pocket business and the cassette business will be described below.

  The open pocket business is a method of setting the ticket type for stacking the temporary stackers 57b to 62b of the stacking devices 57 to 62 as the final stacking location of the paper sheets P for each stacking device. In this embodiment, when 100 sheets are accumulated in the temporary accumulation boxes 57b to 62b, the impellers 57a to 62a are stopped and no further accumulation is performed unless other temporary accumulation boxes 57b to 62b are set. . Therefore, 100 sheets of paper sheets accumulated in the temporary accumulation boxes 57b to 62b are taken out by the operator. Details will be described in detail with reference to FIG.

  The cassette business is a method of storing paper sheets stacked in the temporary stackers 57b to 62b of the stackers 57 to 62 as cassettes in the cassettes 57e to 62e disposed below the temporary stackers 57b to 62b. It is.

  The cassette job is a cassette 57e in which the paper sheets P collected in the temporary stacker 57b are stored as a storage due to factors such as the paper sheets in the temporary stacker 57b being full, an instruction from the operation display unit, or the end of the job. Store in. In this storing operation, when the shutters 57c and 57c arranged at the lower part of the temporary stacking box 57b are opened, the paper sheets P in the temporary stacking box 57b fall on the backup plate 57d provided in the cassette 57e. . At that time, the push-down mechanism 57f arranged on the temporary stacker 57b and capable of moving up and down pushes the paper sheet P on the cassette 57e into the cassette 57e. This pushing force lowers the backup plate 57d in the cassette 57e. Thereafter, after the pushing mechanism returns to the initial position, the shutter 57c is closed.

  The cassette 57e can be exchanged for the cassette 57e set in the stacking device 57 according to an instruction from the operation display unit when the paper sheet P is full during business.

  The specific operation is as follows. First, the main body 1 unlocks the cassette 57e when an exchange operation based on the above conditions occurs. Next, the operator removes the unlocked cassette 57e from the stacking device 57, removes the paper sheet P from the cassette, and prepares another cassette that does not contain the paper sheet P or from the cassette. The paper sheet P is extracted, the cassette 57e which has been emptied is returned to the stacking device 57 again, and the released lock is locked again when the cassette replacement is completed.

  In the open pocket business, when a specified number of sheets (for example, 100 sheets) is accumulated in the temporary accumulation box 57b, an operator opens the temporary accumulation box door and pulls out the paper sheet P from the temporary accumulation box. A band is wound by the operator on the extracted paper sheet P (band winding process).

  FIG. 3 is a diagram illustrating a state in which the paper sheets P are stacked by the stacking device 57. Since the accumulation devices 57 to 62 are similarly configured as described above, the operation of the accumulation device 57 will be described here.

  The paper sheet P conveyed by the conveyance path 24 is discharged from the end of the conveyance path 24. The discharged paper sheet P is taken in between the blades of the impeller 57a. In this taking-in operation, when a paper sheet is detected by a sensor (not shown) arranged in the conveyance path 24, the paper sheet P is taken between the blades and the blades are synchronized with the rotation of the impeller.

  The paper sheet P taken in this way falls with the rotation of the impeller 57a and is accumulated in the temporary accumulation box 57b.

  In the open pocket business described above, when the paper sheets P accumulated in the temporary accumulation box 57b in this way reach a predetermined number (for example, 100 sheets), the impeller 57a stops rotating and is not accumulated any more. Then, the paper sheets P collected in the temporary storage are processed by the operator.

  On the other hand, in the above-described cassette business, the sheets P stacked in the temporary stacker 57b in this way are opened at the shutters 57c and 57c when the predetermined number of sheets are reached or when the stacking process is completed. Is stored in a stored storage (cassette). At this time, the stored paper sheet P is pushed down by the push-in mechanism 57f into the cassette.

  FIG. 4 is a diagram for explaining the push-in mechanism of the stacking apparatus shown in FIG. 3, and shows the push-in state. The backup plate 57d is also lowered by the pushing operation by the pushing mechanism.

  FIG. 5 is a diagram for explaining taking out of paper sheets in the open pocket business. The figure shows a state where the paper sheets P that have reached a predetermined number (for example, 100 sheets) are taken out by opening the front door 51 of the stacking box. This figure shows a case where the paper sheets P collected in the stacking device 61 are taken out, and the temporary stacking door of the stacking device 61 is omitted and the inside thereof is shown.

  The temporary storage door is provided for each temporary storage, and in the open pocket business, the temporary storage door can be opened and the paper sheet P can be taken out. At this time, as shown in FIGS. 3 and 4, shutters 57c and 57c and a pushing mechanism 57f are provided therein, and there is a problem that they may be driven when the above-described driving conditions are satisfied. It was. In this embodiment, in order to ensure this safety, an open pocket safety device shown in FIG. 6 is mounted.

  FIG. 6 shows a safety device for an open pocket door (temporary storage door) according to the present embodiment used in the open pocket business. The temporary storage door is provided with an opening / closing detection switch 57g as an opening / closing detection sensor for detecting opening / closing of the door.

  The open / close detection switch 57g is turned off when the open pocket door (temporary stacking box) is opened, interrupts the coil currents of the relays 57h and 57j, and turns on the push-in mechanism motor 57i and the shutter mechanism motor 57k. Shut off the power supply for driving. As a result, even if the shutter mechanism or the push-in mechanism for driving the shutter 57c is in operation when the temporary stacker is opened in order to take out the paper sheets P stacked in the temporary store 57b in the open pocket business. Since the power to the shutter mechanism motor 57k and the pushing mechanism motor 57i for driving them is cut off, it is possible to prevent the danger of being caught.

  As a matter of course, the power shut-off state of the shutter mechanism motor 57k and the push mechanism motor 57i is such that when the open pocket door is closed and the switch 57g is turned on, the coil currents of the relays 57h and 57j are restored. The power supply for driving the motor 57k and the pushing mechanism motor 57i is restored.

  The cassette business and the open pocket business can be set for each stacking device.

  Furthermore, a sealing part can be arranged as an option, and when 100 sheets are collected in a temporary stacker provided in the sealing part, the collected paper sheets are placed in a belt winding mechanism part (sealing device). It is transported, band-wrapped (sealed), and discharged out of the device.

  In the present embodiment, when the number of sheets P stacked in the temporary stackers 57b to 62b reaches 300 (or 200), they are stored in the cassettes 57e to 62e. Up to 2000 sheets can be stored in the cassettes 57e to 62e, and an operator can set from the operation display unit 202. Details will be described in detail with reference to FIG.

  As described above, when stacking or sealing a certain kind of ticket, the method of stacking in a temporary stack as an open pocket and the number of stacks in the temporary stack used as an open pocket are set to a predetermined number. When it reaches, it is possible to selectively set a method of storing in a cassette provided in the lower stage and a method of sealing with a sealing device.

  In this embodiment, the safety device is described when the opening / closing detection sensor detects the opening of the door when the temporary storage door is opened. However, the present invention is not limited to this, for example, before the integration shown in FIG. Even if the safety device functions when the door is opened, the safety is the same.
