The lower main conveying belt 82 is stretched between a driven roller 92, the roller 91, and a plurality of rollers 93, 94, 95, 96.
[0030]
First to third pulleys 97, 98, and 99 are coaxially attached to the drive roller 87, and the first pulley 97 is a drive pulley of a drive motor 101 that rotates forward and backward as drive means via a timing belt 100. 102. The second pulley 98 is connected to a pulley 106 of a separation kick roller 105 as a separation means via a timing belt 103. The separation kick roller 105 is swingably connected to the support shaft 87 a of the drive roller 87 via the swing arm 107. The third pulley 99 is connected to the driven roller 92 of the lower main conveyance belt 82 via the pulley 108.
[0031]
On the other hand, the roller 84 that spans the upper conveying belt 79 is connected to the support shaft of the roller 85 via the swing arm 110, and a first solenoid 112 as a drive means is connected to the spring 113 by the swing arm 110. Connected through. The swing arm 110 swings when the first solenoid 112 is turned on and off to bring the roller 84 into and out of contact with the lower-side introduction-side transport belt 81.
[0032]
Further, the rollers 93 and 94 that hang the main conveying belt 82 on the lower side are attached to one end portions of substantially 115-shaped arms 115 and 116, and the rollers 95 and 96 are attached to the other end portions of the arms 115 and 116. It is attached. The arms 115 and 116 are rotatably supported by support shafts 117 and 118, and the other ends of the arms 115 and 116 are connected by a link 120.
[0033]
A second solenoid 123 is connected to the arm 115 via a spring 121. When the second solenoid 123 is turned on and off, the arms 115 and 116 are rotated so that the rollers 93 and 94 are moved up and down. It has become.
[0034]
As shown in FIG. 8, a third solenoid 126 is connected to the swing arm 107 of the separation kick roller 105 via a spring 125, and the separation kick roller 105 is moved up and down by turning on and off the third solenoid 126. It is swung to and from a bill.
[0035]
Moreover, the 1st-6th optical sensors 128-133 for detecting a banknote over the conveyance direction of a banknote are arrange | positioned at the banknote taking-in conveyance mechanism 26. As shown in FIG.
FIG. 10 is a block diagram showing a control system for the first to third solenoids 112, 123, 126 and the drive motor 101.
[0036]
The first to fourth optical sensors 128 to 131 are connected to the control means 135 via signal paths.
When the first optical sensor 128 detects the banknote, the control unit 135 turns on the first and second solenoids 112 and 123 and drives the drive motor 101, and the third optical sensor 130 detects the banknote. Then, the first and second solenoids 112 and 123 are turned off, and the third solenoid 126 is turned on and off at a timing described later.
[0037]
Further, when the fourth optical sensor 131 passes the bill within a specified time and does not become bright when the bill is separated and taken out, the control means 135 determines that a pick-up error has occurred and reversely drives the drive motor 101. At the same time, the first and second solenoids 112 and 123 are turned on.
[0038]
Next, operation | movement of the banknote taking-in conveyance mechanism 26 is demonstrated, also referring the flowchart of FIG.
As shown in FIG. 6, when the bill 4 is inserted in a stacked state from the insertion slot 6, the bill 4 blocks the light emitted from the first optical sensor 128, and the first optical sensor 128 is dark. It will be in a state (step ST1 of FIG. 11). As a result, the drive motor 101 starts driving (step ST2), the conveyor belts 77, 78, 79, and 80 run, and the first and second solenoids 112 and 115 are turned on (step ST3). , 93, 94 move.
[0039]
As shown in FIG. 7, the movement of the roller 84 moves the conveyance belt 79 toward the conveyance belt 81 to grip the bill 4, and the movement of the rollers 93 and 94 moves the conveyance belt 82 to the conveyance belt 80. It moves toward and holds the banknote 4. As a result, the banknote 4 is held and conveyed by the conveyor belts 77, 78, 79, and 80.
[0040]
In this way, the banknotes 4 are held and conveyed by moving the conveyor belts 79 and 82, so that the inserted banknotes 4 are securely held regardless of the number of sheets and the lower part of the separation kick roller 105 (banknote separation part). It is conveyed to.
[0041]
When the leading edge of the bill passes through the third sensor 130 by this conveyance, the third sensor 130 becomes dark (step ST4), and the excitation of the first and second solenoids 112 and 123 is released (step ST5). . As a result, as shown in FIG. 8, the transport belt 79 and the transport belt 82 are moved away from the transport belt 81 and the transport belt 80. From this state, the third solenoid 126 is turned on (step ST6). As a result, the separation kick roller 105 is rotated toward and away from the banknote 4, and the banknotes 4 are separated and taken out one by one. After this take-out, it is determined whether or not the fourth optical sensor 131 detects the banknote 4 within a specified time and enters a dark state (step ST7). When the fourth photosensor 131 is in a dark state, the third solenoid 126 is turned off (step ST8). Next, when the bill 4 passes through the fourth optical sensor 131 and the fourth optical sensor 131 enters a bright state (step ST9), it is determined whether the third optical sensor 130 is in a bright state or a dark state. (Step ST10). If all the banknotes 4 are taken out and the third optical sensor 130 is in the bright state, the operation is terminated, and if it is in the dark state, the process returns to step ST6 and the third solenoid 126 is turned on by the separation kick roller 105. Separate and take out banknotes. Thereafter, the same steps are repeated to separate and take out banknotes.
[0042]
On the other hand, when the taken-out banknote 4 does not reach the fourth optical sensor 131 and the fourth optical sensor 13 does not enter the dark state in the above-described step ST7, the drive motor 101 is reversely driven (step ST11). Further, the first and second solenoids 112 and 123 are turned on (step ST12). As a result, the rollers 84, 93, and 94 are moved by the rollers 84, 93, and 94 in the same manner as the above-described insertion of the bills, and the bills 4 that are not separated and remain in the bill separator are held by the conveyor belts 77, 78, 79, and 80 As shown in FIG. 9, it is conveyed in the discharge direction and returned to the insertion port 6. By this return, the second photosensor 129 changes from dark to bright (step ST13). Due to this change, the drive of the drive motor 101 is stopped (step ST14), and then the first and second solenoids 112 and 123 are turned off (step ST15), and the process ends.
[0043]
FIG. 12 shows the operation of the separation kick roller 105 at the time of banknote separation.
The separation kick roller 105 is swung by turning on and off the third solenoid 126 to separate and send out the banknotes 4 one by one.
[0044]
By the way, when the banknotes are separated and sent out, the top surface position of the banknotes is lowered every time the banknotes are sent out, so that the stroke distance of the third solenoid 126 is increased accordingly. For this reason, the pitch between the banknotes to be sent out becomes longer each time the banknotes are sent out.
[0045]
Therefore, in this embodiment, the operation timing of the third solenoid 126 is set as shown in FIG.
That is, the third solenoid 126 is turned on every time the rear end of the banknote 4 passes through the fourth sensor 131, and the timing of turning on is set to be shortened by a certain time each time the banknote is sent out. .
[0046]
Thus, by setting the operation timing of the third solenoid 126, the difference in the bill delivery interval can be reduced, and bills can be sent out at a constant pitch.
[0047]
【The invention's effect】
As described above, according to the present invention, the first and second traveling members are provided so as to be movable toward and away from each other, and the first and second traveling members are moved toward each other to move the sheets. Since it holds and conveys (banknotes), it can be reliably conveyed regardless of the number of paper sheets (banknotes).
[0048]
Further, when an error in separating paper sheets (banknotes) occurs in the separating means, the first and second traveling members are moved toward each other to hold the paper sheets (banknotes), and then the first and second Since the traveling member of 2 is reversely moved, even if a take-out error occurs during the processing operation, it is possible to return a paper sheet (banknote) to the insertion slot without causing an error on the spot, and a processing device with a low error rate. Can be provided.
[0049]
Further, since the drive timing of the drive means for reciprocating the separating means is advanced each time the separating means separates the sheet (banknote), it is possible to correct the increase in the bill pitch due to the operating distance of the drive means. And a processing device with a high processing speed can be provided.
