Abstract

PURPOSE:To continuously convey a large number of paper sheets stably further accumulate them continuously by providing in right and left opposed side walls a pair of pawls for accumulating the paper sheets on them, while those paper sheets being press moved to a partitioning plate under the pawls by means of an accumulating plate, thereafter action of accumulating the paper sheets being repeated again in an accumulating area in an upper part of the pawls. CONSTITUTION:A feed roller 7, feeding a paper sheet 13 sheet by sheet from a conveying path 9, and a sweeper roller 6, having a plurality of blades pressing a rear end of the paper sheet 13 in one direction, are successively provided in line with an upper part of an accumulating area 5 formed in space by an accumulating plate 1a and a pair of right and left pawls 2 provided in the lower of the plate 1a. At this time, the pair of pawls 2 on both right and left side walls 10, 11 are tilted downward and turnably urged upward by a spring, while a partitioning plate 3, urged upward by a spring 4, is provided in a lower part of the pawl 2, further a belt mechanism 1, possible to lift the accumulating plate 1a in the upper part to a position of the pawl 2, is provided. Thus pressing the accumulated paper sheets 13 onto the partitioning plate 3 by the accumulating plate 1a, a series of accumulating operations are performed while a constant accumulating area 5 is ensured in the upper part.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet stacking device for stacking and stacking a large number of paper sheets.

[Conventional technology]

As shown in FIG. 3, a conventional paper sheet stacking device for stacking and stacking a large number of paper sheets uses a spring 24 to move paper sheets 33 released into a stacking area 25 upward. Place and accumulate on the biased partition plate 31,
The partition plate is gradually lowered depending on the weight of the accumulated paper sheets, thereby securing the capacity of the accumulation area 25 formed by the side plates 30 and 31 and the upper part of the partition plate 23.

[Problem to be solved by the invention]

As mentioned above, in conventional paper sheet stacking devices, the partition plate gradually descends according to the number of paper sheets stacked, so the capacity of the stacking area can be secured, but the paper sheets are not easily combed. If the stacking area is large and occupies a large space within the stacking area, there is a drawback that the stacking area becomes smaller and the number of stacking failures increases. In addition, since there is a gap between the partition plate that is urged upward by the spring and the side plate of the stacking area, there is also a drawback that the discharged paper sheets get caught in the gap, resulting in poor stacking.

[Means to solve the problem]

The paper sheet stacking device of the present invention includes a feed roller that sends out the paper sheets that have been conveyed in a conveyance path, and a device that presses the rear end of the paper sheets that have been sent out by the feed roller in a fixed direction. a sweeper roller having a plurality of blades;
a stacking plate that guides the feeding direction of the paper sheets; a pair of claws provided below the stacking plate and urged to rotate upward by a spring that supports the bottom surface of the paper sheets; , a partition plate provided below the wind and urged upward by a spring; a first side plate that contacts the front end of the paper sheet; and a partition plate provided at a position opposite to the first side plate that contacts the front end of the paper sheet. It includes a second side plate that contacts the rear end of the leaves, and a belt mechanism that operates to pull the accumulation plate down to the wind position.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing one embodiment of the present invention, and FIG. 2 is a side view showing one embodiment of the present invention.
FIG. 3 is a side view showing the operation of the illustrated embodiment.

The embodiment shown in FIG.
0 and 11 form an accumulation area 5.

The belt mechanism section l is connected to the motor 12. A conveyance path 9 is formed by a feed roller 7 and a sweeper roller 6.
The paper sheets 13 ejected from the machine are accumulated in the accumulation area 5, and when the series of operations is completed, the motor 12 is activated by a command from the control system (not shown) and the paper sheets 13 are conveyed through the belt mechanism section 1. After the stacking plate 1a rotates around the left end fulcrum 1b so that its right end approaches the claw 2, the motor 12 reverses and the stacking plate 1a returns to its pre-operation state.

Next, the state of stacking a large number of paper sheets will be explained with reference to FIG.

As shown in FIG. 2(a), the paper sheets 13 that are separated and conveyed one by one pass through the conveyance path 9 and are accumulated on the claws 2 in the accumulation area 5. Next, as shown in FIG. 2(b), when the series of stacking operations is completed, the motor 12 is activated by a command from the control system (not shown), and the stacking plate 1a is rotated in the direction of arrow A in the figure. do. At the same time, the already stacked paper sheets 13 and the partition plate 3 both descend in the direction of arrow B in the figure, and at this time the claw 2 also retreats in the direction of the side plates 10 and 11 (arrow C). As a result, the paper sheets 13 are lowered to a position below the claws 2, and the operation of the stacking plate 1a is stopped. Next, as shown in FIG. 2(C), paper sheets 13
After all of the paper sheets 13 and the partition plate 3 are in the position below the claw 2, the claw 2 returns in the direction of the arrow by the force of the spring, and the paper sheets 13 and the partition plate 3
The only part is pressed against the lower surface of the pawl 2 by the spring 4 and stopped, and the upper surface of the pawl 2 secures an accumulating area of a certain size above it for the next accumulating operation. By repeating this operation, the continuously conveyed paper sheets 13 can be stacked one after another and a large number of sheets can be stacked.

〔Effect of the invention〕

As explained above, the paper sheet stacking device of the present invention moves the stacking plate up and down for each series of operations during the stacking operation of a large number of paper sheets, thereby removing the already stacked paper sheets. The effect is that the stacking area above the claw can be secured at a certain capacity by moving it under the claw, and by repeating this operation, it is possible to stack a large number of sheets stably and continuously. There is an effect.
