Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic paper handling device that stacks and separates transported paper sheets.

[Background of the invention]

Conventional automatic paper handling devices include, for example, as disclosed in Japanese Patent Application Laid-Open No. 58-220043,
The paper sheets accumulated in the accumulation section are fed out. A vacuum drum is used as the feeding means, and the paper sheets are adsorbed by vacuum and separated and fed out. This conventional method requires a device to generate a vacuum, which increases the size of the device, and requires folding to separate and take out the paper sheets using the suction force when the paper sheets are attracted by the vacuum. It is conceivable that the suction force is not sufficient for paper sheets that are damaged or torn, and that the separation and feeding performance of the paper sheets is deteriorated.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic paper handling device that improves the reliability of stacking and separating and feeding out paper sheets and has a compact structure.

[Summary of the invention]

Next, an embodiment of the apparatus of the present invention is shown in FIGS. 2 to 5.
This will be explained using figures. Belts 20 and 21 and belts 22 and 23, which constitute a conveying means for carrying banknotes B into the apparatus, are arranged to face each other, respectively. Belts 20 and 22 engage rollers 25 and 26 supported on shaft 24, and belts 21 and 23 engage rollers 28 and 29 supported on shaft 27. Although not shown, these shafts 24 and 27 are driven by separate drive means to drive each of the belts described above. The impeller 30, which is one of the components of the impeller stacker unit (impeller receiving guide means) 14, has a plurality of blades 31 for receiving banknotes on the circumference.
are installed at equal intervals. This impeller 30
is located near rollers 25, 28 and rollers 26, 29, and the opening between blades 31 is located near rollers 25, 28 and rollers 26, 29.
5, 28 and rollers 26, 29 so as to face in a common tangential direction. Thereby, the banknotes B being conveyed while being held between the belts 20 and 21 and the belts 22 and 23 can be pushed between the blades of the impeller 30. The impeller 30 rotates around a shaft 32, and the shaft 32 is supported by an arm 33. The arm 33 is loosely fitted onto the shaft 27 and is integral with the shaft 35. The shaft 35 is located on both sides of the impeller 30 so as not to interfere with the impeller 30, and is fixed to the main body chassis 36, respectively. A gear 37 is attached to the aforementioned impeller 30 so as to rotate together therewith. (One impeller 30
The gear does not appear in the diagram. ) The gear 37 is rotatably attached to the arm 33. It meshes with gear 38. This gear 38
meshes with a gear 39, and this gear 39 rotates integrally with a shaft 40 which is rotationally driven by another drive means (not shown).

A stopper 41, which serves as a locking means for releasing the banknote B guided by the impeller 30 from between the blades 31, is arranged to avoid the impeller 30 so as not to interfere with the blades 31 of the impeller 30. Although not shown, it is driven up and down by another driving means. A roller 42 serving as a feeding means for separating and feeding out banknotes accumulated in a stacking box (accumulating section) 43
In this embodiment, among the banknotes stacked in the stacking box 43, the highest banknote is fed out to the separation section side which will be described later. This roller 42 is connected to the arm 44
is rotatably supported. It can rotate integrally with the shaft 45. This arm 44 is fixed to a shaft 46 that is rotatably supported by the main body chassis 36 and can rotate integrally with the shaft 46, and is rotated about the aforementioned shaft 46 by another driving means (not shown). ,
The arm 44, the shaft 46 and the drive means form an integration/separation mechanism. The aforementioned shaft 45 is in contact with the notched roller 47, and the notched roller 47
is integral with a shaft 48 rotatably supported by the arm 44. When the shaft 48 rotates once, the notched roller 47 intermittently contacts the shaft 45 and rotates the shaft 45. The cutout roller 47 rotates together with a belt pulley 49, and a belt 51 is placed between the belt pulley 49 and the belt pulley 50. The belt pulley 50 is rotatably supported on the shaft 46, and integrally fixes a gear 52, which is also rotatably supported on the shaft 46. This gear 52 is the shaft 5
3 and meshes with a gear 54 that rotates integrally with the gear 54. This shaft 53 is rotationally driven by another driving means (not shown). By rotationally driving this shaft 53, the above-mentioned banknote feeding roller 42
rotates intermittently via a notched roller 47. The guide plate 55 is for operating the roller 42 and guiding the bill when it is fed out.
It is provided integrally with the arm 44 on the distal end side of the arm 44.

There is a cutout hole in the center of the guide plate 55, and a portion of the roller 42 protrudes several mm below the guide plate 55 (on the banknote side).

The collection box 43 includes a side plate 43a and a bottom plate (not shown). It moves within this collection box 43.

The push plate 60 is fitted with a guide rod 61, and can be moved up and down in the figure using the guide rod 61 as a guide. A spring 62 is attached to the end of the push plate 60.
One end is hanging. The spring 62 is wound around a roller 64 that is rotatable about a fixed shaft 63. The other end of the spring 62 is fixed to a shaft 65. Although this shaft 65 is not shown,
It has a structure that can be moved up and down by a driving source, or a structure that allows the other end of the spring 62 to be wound up without moving. With such a structure, the driving source can be controlled by an external signal, and the pressing force by the push plate 60 can be controlled. In addition, the pressing force control is
The spring structure is not limited to the above spring structure. A roller 66 serving as a feeding means and a roller 67 serving as a separating means are arranged facing each other in the banknote feeding portion of the stacking box 43, and are supported by shafts 68 and 69, respectively. Although not shown, this roller 66 rotates integrally with a shaft 68 that is rotatably driven by a driving means to feed out the banknotes. Further, the roller 67 is made of a friction member whose frictional resistance with the banknote is greater than the frictional resistance between the banknotes. These rollers 66 and 67 separate the banknotes fed out from the stacking box 43 one by one and transport them to the next conveyance path.

The above configuration enables the following operations.

First, the operation of accumulating banknotes B as paper sheets is performed in the fourth step.
As shown in the figure, the arm 44 is rotated to raise and retract the roller 42 for feeding out the banknote from above the banknote surface so as not to interfere with the impeller 30. Further, the stopper 41 is arranged at the banknote payout position of the stacking box 43 to block the banknote entry port toward the rollers 66 and 67. In this state, although not shown, the banknotes B fed between the belts 20 and 21 and between the belts 22 and 23 are held by the belts 20 and 21 and the belts 22 and 23, and are conveyed to the impeller 30. It is sent between the blades 31 of.
The banknote B held by the impeller 30 is carried by the rotation of the impeller 30, hits the stopper 41 in the space below the impeller 30, is separated from between the blades 31 of the impeller 30, and descends along the stopper 41. They are collected in the collection box 43. Although not shown, the banknotes B stacked in the stacking box 43 are always detected by a banknote stack amount detection means. The push plate 60 is lowered based on this detection signal.

The space between the uppermost bill of the stacked bills B stacked in the stacking box 43 and the impeller 30 acts as a pressing force control means. For example, it is adjusted by a spring 62. That is, as described above, when the number of stacked banknotes increases, this pressing force control means controls the push plate operating mechanism based on the signal from the stacked banknote amount detection means (not shown), and controls the push plate 60. is lowered along the guide rod 61 until the space reaches a constant value.

Next, the operation of separating and taking out banknotes will be explained with reference to FIG. As shown in Figure 3, the stopper 4
1 is retracted from the banknote dispensing position of the stacking box 43 (in this embodiment, retracted upward). Further, the arm 44 is rotated to hold the bill payout roller 42 at the payout position. As a result, in this embodiment, the roller 42 descends together with the guide plate 55,
It is held at a position where it is in contact with the accumulated banknotes. In this state, the spring 62 pushes the push plate 60 up to a position where it contacts the roller 42. The pushed up banknote B is moved by the roller 42 to the gears 52, 53 and the notched roller 4.
When the banknotes are intermittently driven by the rotation of the banknotes 7, the frictional force generated between the banknotes and the rollers 42 causes the uppermost banknote to be sent between the rollers 66 and 67 along the guide plate 55. Furthermore, due to the rotation of the roller 66,
The banknotes are separated from the stacking box 43 and taken out. At this time, the next banknote tries to come out together with the banknote to be taken out, but this next banknote is applied with a frictional resistance force due to the frictional force generated between the banknote and the roller 67 made of a friction member. From there, only the highest banknotes are separated and taken out one by one. Due to this bill removal operation, the stacked amount of bills in the stacking box 43 decreases, but as described above, although not shown, a detection signal from the stacked bill amount detection means causes the push plate 60 to reduce the amount of bill stacked in the stacking box 43. It increases in proportion to the amount. As a result, the roller 42
The pressing force between the roller 42 and the highest banknote in the stacking box is controlled so that it is always within a certain range.

According to this embodiment, the arm 4 including the roller 42
4 can be rotated and retracted between the impellers 30, so that it is possible to avoid interference between the banknotes sent during stacking of banknotes and the roller 42, and thereby the banknotes are stacked by the impeller 30 and the roller 42
Separation and feeding of banknotes by and rollers 66, 6
7 can be implemented in combination with the separating and taking out of banknotes, and it is also possible to improve the stacking and separating and feeding performance for folded and torn banknotes. Furthermore, since the position of the impeller is fixed when separating and taking out paper sheets, the space on the upper side can be reduced compared to a structure in which the impeller is retracted upward, resulting in a compact device.

In addition, in the above embodiment, the case of handling banknotes as the paper sheet was explained, but the present invention is not limited to banknotes, and the same effects can be achieved with respect to other paper sheets as well.

〔Effect of the invention〕

According to the present invention, it is possible to provide a paper sheet handling device with a compact structure that improves the reliability of sheet stacking and separating and feeding operations.
