[Industrial application fields]
The present invention relates to a paper sheet processing apparatus and a paper sheet processing method for processing a predetermined number of paper sheet bundles bundled in a predetermined number.
[0002]
[Prior art]
As this kind of paper sheet processing apparatus, for example, after taking out paper sheets one by one in order and inspecting and counting their quality etc., bundles of bundles collected every certain number of sheets (for example, 100 sheets) are bound by a band-shaped material. There is something to do.
[0003]
An outline of a conventional paper sheet processing apparatus will be described with reference to FIGS.
In FIG. 14 and FIG. 15, a plurality of paper sheets P inspected for quality are supplied to a predetermined storage position by the supply device 103, and the paper sheets P at this storage position are taken out one by one by the take-out device 104. It is. The taken paper sheet P is transported to the stacking device 106 by the transport device 105 and counted by the counting device 107.
[0004]
The stacking device 106 drops a backup plate 109 that can move up and down along the guide plate 108 and a sheet P that is installed above the backup plate 109 and is transported from the transport device 105 onto the backup plate 109. It consists of an impeller 111 to be made. The backup plate 109 on which a certain number of paper sheets P are placed descends to the lower supply position 109A and stands by.
[0005]
The paper sheet P on the backup plate 109 is received when the carrier 128 of the first binding device 112 moves to 109A. The carrier 128 responsible for the paper sheet P moves to the binding position 128A in the vicinity of the first binding device 112. The sheet P on the carrier 128 at the first binding position 128A is wound by the first bundling device 112 with a heat-meltable strip-like material, and then the belt-like material is thermocompression-bonded and bound. The paper sheets P bound to one bundle are transferred from below the first binding position 112.
[0006]
The transferred bundles are received one by one in the bundled state by the backup in the second binding device 113. Each time this bundle is received, the backup is moved by a predetermined amount and sequentially stacked in the surface direction until a predetermined number (for example, 10 bundles) is reached. After stacking, the predetermined number of bundles on the backup are transferred to the compression unit in the horizontal direction by the transfer means, and after compressing the predetermined number of bundles in the compression unit, the binding band is wound around and thermocompression bonded, The second bundling device 113 is transferred to the discharge device 114 from the lower right.
By the way, the amount of the paper sheets collected in the second bundling device 113 may increase in the thickness direction due to dirt, wrinkles and the like.
[0007]
[Problems to be solved by the invention]
However, conventionally, even if the amount of paper bundles collected in the second bundling device 113 becomes dirty and wrinkles increase in the thickness direction, the moving means from the stacking unit to the compression unit remains as it is. It was sent into a certain remover case.
[0008]
For this reason, the paper sheet bundle cannot be accommodated within the capacity of the remover case, and it interferes with the positioning guide or the upper surface of the compression part, thereby damaging the remover case itself or causing a binding failure. There was a problem that the binding process could not be performed well.

[0024]
Next, the operation of the above apparatus will be described.
First, a paper bundle A wound in a predetermined number (for example, 100) is delivered onto the shutter plate 6 and detected by the sensor 11, the solenoid 8 is excited and the arm 9 is moved in the direction of arrow a. And the shutter plate 6 is opened. By this opening, the paper bundle A is accumulated on the backup plate 17, and when a predetermined time elapses, the excitation of the solenoid 8 is released and the shutter plate 6 is closed. Every time the paper bundle A is received, the shutter plate 6 repeats this operation. The backup plate 17 is lowered by a predetermined amount via the timing belt 21 when the pulse motor 24 rotates by a predetermined number of pulses after a predetermined time from the detection when the shutter plate 6 is opened. The backup plate 17 is lowered by a predetermined amount every time the paper leaflet A is received. Thereby, when a predetermined number (for example, 10 bundles) is received by the backup plate 17, the backup plate 17 moves to the lowermost end in the 10th bundle. The ten bundles on the backup plate 17 are transferred onto the guide plate 31 when the backup plate 17 is lowered below the bottom surface 31 a of the guide plate 31. When the backup plate 17 is detected by the lower end sensor 26, the guide plates 29, 30, 31 and the paper bundle A in the guide plates 29, 30 , 31 move to the binding unit 3 together with the sub-base 34, 13, the guide plates 29, 30, 31, the paper bundle A, and the sub-base 34 are once stopped at the position C in front of the compression plate 50, and the retractable guide provisions 29, 30, 31 are placed on the bottom surface of the guide plate 31. The pulse motor 39 is rotationally driven and raised to a position where 31a does not interfere with the upper surface of the compression plate 50. Further, the guide plates 29, 30, 31 and the paper bundle A are transferred in parallel to the position D of the binding unit 3 by driving the motor 36. At this time, the guide plates 29, 30 and 31 move to the bundling portion 3 and at the same time the leaf spring 61 and the cam follower 62 mounted on the upper left of the guide plate 9 pass through the plate cam 63, so that the sheet bundle A is removed from the upper surface. Drive in the direction of arrow b so as to hold down the upper end surface. It moves to the binding unit 3 while holding down the upper end surface of the tenth paper bundle A. When the paper bundle A is transferred to the binding unit 3 , the back-up plate 17 rises to the position of the upper end reference sensor 25 to receive the next one grip.
[0025]
Thereafter, 10 bundles are sequentially accumulated in the same manner, and the paper bundle A is continuously supplied to the next operation. The paper bundle A in the guide plates 29, 30, 31 is compressed between the compression unit upper surface plate 49 while being guided in the compression direction by the guide plates 29, 30, 31 as the compression plate 50 rises. When the paper bundle A is compressed, the pulse motor 39 for contracting the telescopic guide plates 29, 30, 31 is rotated and the guide plates 29, 30, 31 are contracted. The guide plates 29, 30, 31 are positioned below the compression plate 50 with the guide plates 29, 30, 31 contracted. It remains in the belt winding 48 and returns to the original position. The compressed paper bundle A is wound by the band winding section 48 and, after the band winding is completed, is transferred to a discharge device outside the apparatus and discharged.
[0026]
Note that the paper bundle A has already been stacked on the next n bundle and the backup plate 17 by the time the guide plates 29, 30, 31 are returned to their original positions. Since the guide plate 29, 30, 31 returns to the paper bundle A that is being accumulated, the next 10 bundles are continuously received and transferred to the band winding portion 48. Can be transported.
[0027]
【The invention's effect】
As described above, according to the present invention, the position of the bottom portion of the storage unit that receives the stacked paper sheet bundle transferred by the transfer means is set so that the storage depth dimension of the storage unit is larger than the stack height of the paper sheet bundle. Even if the amount of accumulated paper bundles increases in the thickness direction due to dirt, wrinkles, etc., the paper leaflets are completely stored within the capacity of the storage unit and aligned. Interference with the guide or the upper surface of the compression portion can be reliably prevented.
[0028]
Accordingly, the bundling process can be performed satisfactorily without damaging the storage section itself.
In addition, since the upper surface of the paper sheet bundle stored in the storage section is pressed and compressed by the compressing means, the accumulated paper sheet bundle is transferred in the thickness direction due to dirt, wrinkles, etc. Even more reliably, the paper sheet bundle can be stored in the capacity of the storage unit, and interference with the alignment guide or the upper surface of the compression unit can be prevented, and a good bundling process can be performed.
