Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a paper sheet stacking apparatus, and in particular, forms a stacking section for temporarily stacking paper sheets for return on a transport path efficiently, The present invention also relates to a sheet stacking device suitable for conveying and stacking one or more return bills.

[Prior Art] A conventional apparatus is described in JP-A-63-17764,
A transport member having both functions of a transport path for paper sheets and a temporary stacking section is composed of an upper movable plate, several upper transport rollers, a lower movable plate, several lower transport rollers, and front and rear peripheral walls. It is configured. In addition, the bladed roller for depositing the sheets on the temporary stacking section is provided in the temporary stacking section so that when the lower movable plate rises and the sheet conveying path is formed, the sheet is not hindered. It is configured to move to a position far away from the entrance.

Further, as described in Japanese Patent Application Laid-Open No. Sho 62-26351, a conventional apparatus includes a paper sheet holding plate which is inclined from one end of the bottom plate so as to form an obtuse angle with respect to the bottom plate, and covers an upper portion of the holding plate. A paper sheet stacking space is constituted by the cover plate, and a feeding means is provided so as to feed the paper sheets obliquely upward from the other end of the bottom plate toward the upper part of the inner surface of the holding plate. Further, the paper sheet discharged into the stacking space contacts the rotating belt disposed at the lower end of the stacking section after the leading end collides with the lid plate, and forcibly pushes the lower end of the paper sheet forward. This prevents interference with the next paper sheet that is fed and sequentially conveyed.

[Problems to be solved by the invention]

In the first prior art, the pair of movable transfer members is composed of upper and lower movable plates, upper and lower rollers, and front and rear peripheral walls of a stacking section, and a number of components. When the members form a transport path, a contact member whose position changes between the transport operation and the stacking operation is provided to retract the bladed roller so as not to hinder the transport of the paper sheet. A member and a mechanism for changing this position are required, and there has been a problem in trying to reduce the size and measurement of the device.

SUMMARY OF THE INVENTION An object of the present invention is to form an efficient temporary stacking unit integral with a transport path with a mechanism having a small number of parts, to form a paper sheet with a fold or a paper sheet with a weak waist, or a paper sheet with a broken or broken front end. An object of the present invention is to realize a sheet stacking device that stably stacks leaves and that can convey the sheet again.

In addition, it is possible to collect one to multiple sheets at once, and to stably deposit paper with folded paper, weakly stiff paper, or paper with a broken or broken front end. It is another object of the present invention to realize a paper sheet stacking apparatus capable of performing separation and feeding again.

[Means for solving the problem]

In order to achieve the above object, a second transport member arbitrarily provided in a direction approaching and separating from a first transport member for transporting paper sheets, and the second transport member includes the first transport member. Forming a first stacking section for stacking paper sheets between the first and second transport members when displaced in a direction away from the first stacking section; A first stacking roller in which a plurality of elastic members for taking in are radially arranged is arranged at the entrance of the first stacking section, and the first stacking roller picks up the first stacking section. A positioning member that regulates the leading end position of the inserted paper sheet, and a deposition member that deposits the paper sheet deposited on the second transport member side at a position separated from the second transport member, The positioning member retreats from the conveyance path when the second conveyance member is displaced toward the first conveyance member, and the second conveyance section Are displaced in a direction away from the first transport member and return to the original position when a deposition space is formed, and one sheet is disposed at the end of the first and second transport members. A second stacking unit for stacking a plurality of sheets sequentially conveyed one by one or a plurality of sheets conveyed from the first stacking unit;
Is provided with a second stacking roller in which a plurality of elastic members for taking in paper sheets are radially arranged.

[Action]

The conveyed paper sheet engages with the roller at the paper sheet entry portion, but the elastic blades of the bladed roller overlap the paper conveyance path and have a higher rigidity than the paper sheet. Due to the high height, the paper sheet at the portion engaged with the bladed roller is pressed against the conveyance path in the direction opposite to the bladed roller and is deformed.

Thereby, the paper sheet is deformed into a waveform in the direction perpendicular to the transport direction by the transport means and the bladed roller, and the transport path is rotated in a direction opposite to the bladed roller in a state where rigidity in the transport direction is increased. Is guided to the front plate at the front end of the stacking section, so it cannot be deformed in the transport direction.
Strongly folded or weakly stiff paper sheets do not come into contact with the previously stacked paper sheets, so even if the front end of the previously stacked paper sheets is broken or broken, stable feeding is possible. It is possible.

Thereafter, the sheet ejected from the conveyance path is forcibly scraped off by the blades made of the elastic body of the bladed roller, and a space is formed in the sheet entering portion, so that the next sheet interferes. Never. In addition, since the bottom sheet is arranged so that the lowermost sheet of the stacked sheets does not come into contact with the conveying means having a conveying force at the lower end of the stacking section, all the sheets are stacked without being pushed forward. Until it is deposited.

After that, one to a plurality of sheets in the stacking section are sandwiched again by the movement of the transport member, and are transported collectively to the next transport path.

One to a plurality of paper sheets conveyed from the stacking section engage with the rollers at the second stacking section entry section, but the bunch of elastic brushes of the brush rollers is moved along the paper path. Alternatively, since the sheet is overlapped with the guide member and has higher rigidity than the sheet, the sheet in the portion engaged with the brush roller is pressed against the conveying path or the guide member in the direction opposite to the brush roller and deformed.

As a result, the sheet can be stably deposited in the same manner as described above.

In addition, since the lid plate above the stacking portion is disposed at a position where the rear end of the paper sheet does not leave the brush, there is no delay in the forward operation of the paper sheet rear end by the brush roller. The next sheet does not interfere.

Further, unlike the temporary stacking section in the preceding stage, the stacking section does not need to form a normal transport path, so that it is possible to increase the rigidity of the bunch of brushes made of an elastic body, and the paper piled up at one time can be formed. It can respond to some of the leaves.

FIG. 2 is a diagram showing a detailed arrangement of the bladed roller 5 and the brush roller 24. Bladed roller 5 or brush roller
24 is alternately arranged with the roller 4 or the roller 23, and the belt 9 or the guide 26 is arranged to face the roller. Further, the bundle of the blades of the bladed roller 5 and the brush of the brush roller has higher rigidity than the paper sheet, and the passing paper sheet 1 is deformed into a waveform as shown in FIG.
Released to As a result, a paper sheet that is strongly folded in a direction perpendicular to the transport direction is also deformed into a waveform, and is inserted with increased rigidity in the transport direction, thereby enabling stable deposition. However, the sheet 1 ', which is passed when the lower conveying member 12 of the stacking section 17 rises and forms a normal conveying path, that is, the sheet 1' held between upper and lower conveying members, is not deformed. Since the rigidity of the blades of the bladed roller 5 is set so as not to give, the central part of the paper sheet 1 'being conveyed is not deformed as shown in FIG. , And can be stably conveyed without giving.

A series of operations of the present invention will be described with reference to FIG. Fig. 3-
As shown in FIG. 1A, the sheet 1 conveyed to the stacking portion 17 formed by the lower conveyance path 8 of the conveyance path 6 descending, the outer diameter of the bladed roller 5 engaging with the rollers 5, 10 is a belt. 9 and the stiffness of the blade is higher than that of the paper sheet, so that the paper sheet at the portion engaged with the bladed roller 5 is
Deforms in the opposite direction. For this reason, the sheet 1 is deformed by the belt 5 with the bladed rollers 5 in a direction perpendicular to the conveying direction, and is guided by the belt 9 in a state where the rigidity in the conveying direction is increased, so that the sheet 1 Sent until stable. As a result, even when the paper sheet 1 is folded or the waist is weak, the paper sheet 1 does not hang down during loading, and does not come into contact with the previously stacked paper sheet 1 ′. Can be stably deposited even if the front end is broken or broken.

As shown in FIG. 3B, the sheet 1 released from the holding of the rollers 5 and 10 and colliding with the front plate 15 is forcibly and quickly scraped off at the rear end by the bladed roller. For this reason, a space is formed at the entrance of the sheet 1 stacking section 17, and the sheet is stably stacked on the stack 1 'without interfering with the next sheet to be inserted. The pile 1 'is held by the bottom plate 16,
Since it is in a state of being lifted from the rotating belt 12, it can be kept in a well-aligned state without being pushed to the front plate 15 side.

As shown in FIG. 3C, when the stacking operation on the stacking section 17 is completed, the lower conveying member 8 moves up, and the stacked paper 1 'is again narrowed by the upper conveying member 7 and the lower conveying member 8. And begun to be transported in a lump. At this time, the front plate 15 falls forward in conjunction with the raising operation of the lower conveying member 8, so that the sheet 1 '
Is guided by the front plate 15 and smoothly fed.

Sheet 1 'sent from the stacking unit 17 as shown in FIG.
Engages with the rollers 11 and 23, but the outer diameter of the brush roller 24 overlaps with the transport path 19 and the guide 26, and the rigidity of the brush bundle is higher than that of the paper sheet. While being deformed into a waveform by the conveyance path 19 and the guide 26 and having high rigidity in the conveyance direction, the sheet is guided by the guides 26 and 27 and is fed in a substantially vertical direction without being bent in the middle until it collides with the cover plate 25. Therefore, even if the front end of the previously stacked paper sheet 1 "is broken or torn, it can be stably stacked without being caught. Further, the stacked paper sheet 1 'collides with the cover plate 28. Since the rear end of the paper sheet 1 'is always in a position in contact with the brush roller 24, the rotation of the brush roller 24 causes the paper sheet 1' to be quickly scraped forward, so that the next paper sheet to be inserted Therefore, stable stacking can be performed without interference, that is, stacking of paper sheets continuously fed one by one from the transport path 6 is also possible.

Further, as shown in FIG. 3E, after the stacking is completed, the push plate 33 moves forward, and pushes out the sheet 1 'to the front plate 30 side. Also, at this time, the lid plate 28 moves rearward in conjunction with the movement of the push plate, and the upper part of the stacking unit 25 is released, so that a state of withdrawal or return is possible.
Further, since the guide 27 rotates in conjunction with the forward movement of the push plate, an operation of standing the sheet 1 'by the rotation of the guide 27 is added in addition to the pushing operation of the sheet 1' by the push plate. Even when the paper sheet 1 'is leaning from the front plate 30 side to the guide 27 side, stable extrusion can be performed.

〔The invention's effect〕
