Abstract

PURPOSE:To prevent paper sheets from double feeding, by rotating an eccentric roll installing a frictional contact part on an outer surface of a large diametral part and a delivery roll installing the frictional contat part in a part of the outer surface both synchronously so as to cause each of frictional contact parts to be made contact with these paper sheets at the same time. CONSTITUTION:At the surface central part of piled paper sheets 4, a leverlike support part 8 pressing this central part against a spring 2 is installed. Likewise, an eccentric roll 9 for delivery auxiliary use for these paper sheets is installed in the surface central part of these paper sheets 4, while a rubber pad 7 being large in a friction factor is attached to the outer surface of a large diametral part. On the other hand, a paper sheets delivery roll 5 attaching the rubber pad 7 to a part of the peripheral surface likewise is installed in a lower part of the surface of these paper sheets 4. And, each rubber pad part 7 of both these rolls 5 and 9 is made synchronously contact with the surface of these paper sheets 4, delivering each of them out. If so, after delivering is over, a smooth surface of the roll 5 and a small diametral part of the roll 9 are made face-to-face so that these paper sheets 4 are in no case delivered further.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for dispensing paper sheets, and more particularly to an apparatus for dispensing cut sheets stacked upright one by one from the surface thereof.

Conventional Example 1
Generally, banknotes 4 deposited on a movable plate 3 are fed out one by one by a feeding roll 5 and an auxiliary roll 6.

In order to reliably feed out banknotes one by one in the banknote feeding device having such a configuration, a rubber pad 7 or the like is attached to a portion of the outer circumferential surface of the feeding roll 5 so that the core portion is in contact with the banknote surface. The auxiliary roll A/6 is constructed in the same manner, and care is taken to ensure that the smooth surface of the roll does not disturb the alignment of the stacked banknotes 4. It is something to do.

However, since the surface condition of the banknote surface and the surface of the two rolls changes from moment to moment, the coefficient of friction between them also changes, and even when the smooth surfaces of the two rolls 5 and 6 come into sliding contact with the surface of the banknote stack 4, the banknote is It had the flaw that it could sometimes roll out.

The present invention has been made in order to eliminate the deficiencies of the conventional sheet feeding devices as described above.

A paper sheet stack support member is provided near the center of the stacked paper sheet surface where the auxiliary roll is disposed, and the auxiliary roll is an eccentric roll whose large diameter portion contacts the paper stack surface and the feed roll It is an object of the present invention to provide a paper sheet feeding device which is fully synchronized with sheet sequential feeding operation.

□Hereinafter, the present invention will be explained in detail based on embodiments shown in the drawings.

FIG. 2 is a configuration diagram showing an embodiment of the paper sheet feeding device according to the present invention.

In this figure, a lever-like stacked paper support part 8 is arranged near the center of the surface of the stacked paper sheets 4 to press the stacked paper sheets against the spring 2 to prevent the stacked paper sheets from collapsing. .

Further, an eccentric roll 9 for assisting paper feeding is provided near the center of the surface of the stacked paper sheets 4, and a rubber pad 7 with a large friction coefficient is attached to the outer peripheral surface of the large diameter part, and the core part of the paper sheets 4 is
The rotational contact with the surface and the rubber of the sheet feeding roll 5
The structure is such that the rotational contact of the feeding section attached to the pad 7 with the surface of the sheet is synchronized with Y.

The sheet feeding device of the present invention constructed as described above functions as follows.

The large diameter of the auxiliary roll 90 rotates in synchronization with the rotation of the paper sheet delivery roll 5 and the rubber pad portion 7 on its outer peripheral surface comes into contact with the surface of the stacked paper sheets 4. The rubber pad also comes into contact with the surface of the stacked paper sheets 4, and the two work together to feed out the top layer of stacked paper sheets.

Even after the above-mentioned feeding operation is completed, both the rolls 5 and 9
continues to rotate until the next feeding operation standby position, but at this time, the fast sliding surface of the outer periphery of the feeding sheet 5 comes into contact with the surface of the stacked sheets, and the small diameter portion of the eccentric auxiliary roll 9 faces the surface. Therefore, the paper sheets are not fed out further, and the paper sheets can be stably fed out one by one.

2. The supporting member for preventing stacked sheets from collapsing does not need to be limited to a lever-like member as shown in FIG. 9. For example, wJ3
The eccentric auxiliary rolls 9,9. A support roll 11.11 with a smooth outer peripheral surface coaxially with the rotating shaft 10 of...
・・・・・・ Bearing 12.12.・・・・・・
It is obvious that it may be loosely fitted through the .

Since the present invention is configured and functions as explained above, it is possible to reliably dispense paper sheets one by one like a cash dispenser. This is extremely effective in preventing accidents caused by unexpected feeding of paper sheets other than during paper sheet feeding operations in the required apparatus.
