Description

  Embodiments of the present invention relate to a paper sheet cutting apparatus that cuts paper sheets such as banknotes.

  This type of paper sheet cutting apparatus has a take-out section for taking out paper sheets in the main body of the apparatus. The paper sheets taken out from the take-out section are transported along a transport path, and the paper sheets are transported during the transport. It is determined whether the kind is cleavable or should be re-inspected, and the cleavable part is conveyed to a slicing section and cut.

  Some of these paper sheet cutting apparatuses are capable of cutting paper sheets offline. When cutting off-line, the exterior cover (safety cover) of the apparatus main body is opened, the paper sheet is set in the input portion provided in a part of the transport path, and the cutting switch is turned on. Thereby, when the cutting blade of the cutting unit starts rotating and reaches a predetermined rotation speed, the conveying belt of the conveying unit is rotated to convey the paper sheet to the cutting unit and cut.

  However, conventionally, since the operation is performed with the exterior cover (safety cover) of the apparatus main body opened, it is necessary to cut off the power according to the CE mark standard.

  Further, since the input unit can be accessed during normal operation, there is a problem that paper sheets are erroneously set in the input unit and cut.

  Furthermore, since the counting is not performed at the time of offline cutting, there is a problem that the number of cuts must be managed by a human system.

  The mode setting button 6a, the operation start switch 6b, the open / close check sensor 5a, the cutting switch 3, the detection switch 3, and the sensor system 11 are connected to the control unit 30 via a transmission circuit, and the control unit 30 includes a control circuit. The take-out rotor 9, the conveyance path section 10, the alarm (alarm means) 5 b, the cutting section 16, the rotary solenoid 23, and the switching gates 13 a and 13 b are connected via the above.

  Next, the operation of the paper sheet processing apparatus configured as described above will be described.

  First, in the normal processing mode, the operator sets paper sheets in the hopper 8, and then sets the normal processing mode by the mode setting button 6a and turns on the operation start switch 6b. As a result, the take-out rotor 9 is rotated and taken out one by one from the uppermost paper sheet of the paper sheet group S onto the conveyance path 10. The taken-out paper sheets are transported along the transport path 10 and inspected by the sensor system 11. Based on the detection result, the control unit 30 determines whether it can be cut or not and requires re-examination. Then, the switching gates 13a and 13b are switched in a predetermined direction at a predetermined timing according to the determination result. With this switching operation, paper sheets that need to be re-inspected are sent to the reject ticket stacker 15 via the first branch path 10a and accumulated, and those that can be cut are cut via the second branch path 10b. It is conveyed to the section 16 and cut.

  In addition, when a paper sheet to be sent to the reject ticket stacking box 15 is mistakenly sent to the second branch path 10b, it is transported to the reject box 17 and collected by the switching operation of the second branch gate 13b. .

  Further, the paper sheets accumulated in the above-described rejected ticket accumulating unit 15 and reject box 17 are taken out by the operator, set in the hopper 8 and processed again.

  Next, the case of cutting paper sheets offline will be described.

  In this case, the mode setting button 6a is used to switch from the normal cutting mode to the offline cutting mode. After that, the key of the opening / closing door 5 of the insertion port 2 is removed and the opening / closing door 5 is opened. At the time of opening, the open / close check sensor 5a is turned on. When the opening / closing check sensor 5a detects that the opening / closing door 5 of the insertion slot 2 is opened during processing in the normal cutting mode, the processing is immediately stopped and an alarm is issued by the alarm 5b. .

  After the opening / closing door 5 is opened, a paper sheet is loaded into the loading slot 2. After this input, the cutting switch 3 is turned on. When the switch is turned on, the cutting blade of the cutting unit 16 is rotationally driven, and the conveyance path unit 10 starts operating when the cutting blade reaches a predetermined rotation speed.

  As a result, the sheets fed into the insertion slot 2 are nipped and taken in by the conveyance belt 31 and the pinch roller 30, sent out along the conveyance guide body 32 to the conveyance path 10, and conveyed.

  The paper sheet is guided and conveyed to the second branch conveyance path 10b by the switching gate 13a, and the length and thickness of the paper sheet are detected by the detection sensor 19 on the downstream side. This detection data is transmitted to the control unit 30 to check whether or not the paper sheet has a predetermined length and thickness.

  When it is determined that the paper sheet has a predetermined length and thickness, the rotary solenoid 23 is operated to rotate the shutter blades 21a and 21b in the direction of arrow A in FIG. As a result, the projections 21c and 21d of the shutter blades 21a and 21b come into contact with the stopper 24 and stop, and the inlet 16a of the cutting part 16 is opened. The paper sheets are introduced into the cutting unit 16 from the opened introduction port 16a and cut.

  When it is determined that the paper sheet is not a predetermined length and thickness, the rotary solenoid 23 is operated so that the shutter blades 21a and 21b rotate in the B direction and abut against the conveying roller 35 and stop. The 16 inlet ports 16a are closed. As a result, the paper sheets abut against the shutters 21a and 21b, and the introduction of the paper sheets into the cutting portion 16 is restricted. During this blockage, the dog 25 blocks the optical axis of the sensor 26 and it is detected that the shutter 21 has been operated.

  In addition, when the conveyance speed of the paper sheets described above is sufficiently slow, cutting of the paper sheets can be prevented by stopping the conveyance of the paper sheets, but within the time when the paper sheets are conveyed to the cutting unit 16. When the conveyance cannot be stopped, it is necessary to prevent the cutting of the paper sheet by closing the inlet 16a of the cutting unit 16 with the shutter 21 that operates fast as described above.

  As described above, according to this embodiment, in order to provide the paper sheet insertion slot 2 on the side surface of the apparatus main body 1, the paper sheets are input from the outside of the safety cover of the apparatus main body 1 and cut. It is possible to ensure the safety of the operator without interrupting the power.

  In addition, since the opening / closing door 5 is provided in the insertion port portion 2, paper sheets cannot be input from the insertion port portion 2 unless the opening / closing door 5 is opened, and erroneous input of paper sheets can be prevented. it can.

  Furthermore, since the length and thickness of the inserted paper sheets are detected by the detection sensor 19, abnormal paper sheets or a plurality of paper sheets mistakenly input simultaneously are not cut.

  The above-described embodiment is presented as an example, and is not intended to limit the scope of the invention. The novel embodiment can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
