JPS60218253A - Paper-sheets superposing apparatus - Google Patents

Abstract

PURPOSE:To prevent the lifting-up of the superposed paper sheets or the dangling of the paper sheet to be superposed and prevent the generation of jam by installing a nozzle which blows-out air flow and a deflector for deflecting the blown-out air flow in the vicinity of a paper-sheet superposing part. CONSTITUTION:Paper sheets are transported in a direction 14, nipped by two flat belts 5 and 10, and the paper sheets discharged from a pulley 6 are transported further by the frictional force between rubber rollers 11 and 12 coaxially installed with pulleys 1 and 2, and contact with a stopper 13 and stop. At this time, a pushing plate 15 pushes the paper sheets onto the rubber rollers 11 and 12 by the force of a spring 16, and piles the paper sheets. An air nozzle 12 is installed in the vicinity of the pulley 6, and an air-flow deflector 22 is installed in front of the air nozzle 12. The lift-up of the piled paper sheets or the dangling of the paper sheet to be superposed can be prevented by the air flow supplied from the air nozzle 12 or the air flow deflected by the air-flow deflector 22.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an apparatus for stacking paper sheets conveyed one by one by a conveyor belt or the like, and particularly for stacking paper sheets with folds such as banknotes. The present invention relates to a paper sheet stacking device suitable for stacking paper sheets.

[Background of the invention]

2. Description of the Related Art Devices that separate, transport, and stack paper sheets such as banknotes are used in automatic cash handling devices, counting devices, and the like.

Among these, a belt-type deposition device consisting of a belt stretched over a pulley, a roller, a push plate, etc. is widely used as a deposition device, but a belt-type deposition device can be made smaller. It can be made faster.

Capable of increasing capacity. It has many advantages, such as good alignment of accumulated paper sheets, but if the paper sheets you are handling have certain creases or if you are accumulating heavily damaged paper sheets,
It had the disadvantage of causing jams and being cheap.

In other words, when paper sheets with folds are stacked in a direction perpendicular to the conveyance direction, one end of the stacked paper sheets rises due to the folds, as shown in FIG. It blocks the approach path, causing a jam.

In addition, when stacking severely damaged paper sheets, if the number of stacked sheets increases, the paper sheets will swell, and as shown in Figure 1 B.
As shown in the figure, it blocks the approach path for the next sheet.
A jam occurs.

In addition, in the case of another folded paper sheet, as shown in FIG. 1C, the leading edge of the paper sheet that is about to enter will sag), causing a jam when the paper sheets that have been piled up earlier collide with each other.

As explained above, in the conventional belt type deposition device,
The trailing edge of the nine stacked sheets lifts up, or the front edge of the stacked nine sheets hangs down, or the front edge of the stacked nine sheets hits the rear edge of the nine stacked sheets. He had a flaw that made him a shijam.

[Purpose of the invention]

It is an object of the present invention to avoid the advantages of conventional belt-type stackers, which jam when attempting to stack the particular crumpled sheets mentioned above.

To provide a paper sheet stacking device which eliminates the drawback that stacking a large number of severely damaged paper sheets causes jams and becomes cheap.
There it is.

[Summary of the invention]

For the above purpose, the present invention is provided with a nozzle and a deflection plate, and by pressing or deforming the paper sheets with an air flow, it is possible to lift the accumulated paper sheets or to prevent the paper sheets that are about to accumulate from sagging. The purpose is to prevent the occurrence of jams by preventing bottom jams.

[Embodiments of the invention]

Hereinafter, the present invention will be explained in detail with reference to Examples.

FIG. 2 is a diagram showing an embodiment of the present invention.

1 to 4 are pulleys 6 to 9 for tensioning the first flat belt 5;
is a pulley that tensions and passes the second flat belt 10, and the accumulated paper sheets are conveyed in the direction of arrow 14 by being sandwiched between the first flat belt 5 and the second flat belt 10. The paper material released from the paper sheet 6 is further conveyed by the frictional force of the rubber rollers 11 and 12 provided coaxially with the pulleys 1.2, and is stopped against the sheet stopper 13. 16
The force acts to press the paper sheets against the rubber rollers 11, 12, and in this way, the paper sheets are piled up one after another.

An air nozzle 21 is provided near the pulley 6 to create a constant air flow at all times.

An air flow deflection plate 22 is provided in front of the air nozzle 21.

When there are no sheets to be piled up, the air flow from the air nozzle 21 is deflected by the air flow deflection plate 22, and the sheet is pushed against the pushing plate 15, as shown in FIG. 2A. This prevents the accumulated paper sheets from rising up.

Next, FIG. 2B shows a case where a paper sheet enters. The leading edge of the paper sheet discharged from the pulley 6 is pressed in the direction of the first flat belt 5 by the air flow from the air nozzle 21), so that the leading edge does not hang down, and the airflow that hits the paper sheet The direction of the paper can be changed, and the nine sheets are piled up first and pushed down, so the sheets do not stick out and jams do not occur.

FIG. 2C shows a state in which the paper sheet is further conveyed.

The trailing edge of the sheet is conveyed by being pressed against the first belt 15 by the airflow, but when the trailing edge passes halfway through the airflow, it is pushed from the first belt side by the action of the deflection plate 220. It is turned over to the board side and ready for the next sheet to be deposited.

As explained above, according to the present invention, jams can be prevented regardless of whether the accumulated paper sheets are folded or damaged.

〔Effect of the invention〕

・ ４ ・ As explained above, conventional belt-type stacking devices had the disadvantage of generating paper jams depending on paper sheet conditions, but according to the present invention, folding conditions and damage conditions can be reduced. It is possible to eliminate the cause of jamming due to paper sheet conditions.
