Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a paper sheet take-out device that sequentially takes out paper sheets supplied to a supply section one by one in a paper sheet processing apparatus, for example.

Conventionally, as shown in FIG. 1, this type of paper sheet take-out device has been used to collect a group of paper sheets p supplied to a supply section a.
... is pressed in the plane direction by the back-up body b and biased toward the guide plate c for regulating the take-out position, so that the frontmost paper sheet p is passed through the roller protrusion window formed in the guide plate c. The paper sheet p is pressed against the take-out roller d which partially protrudes, and as the take-out roller d rotates, the frontmost paper sheet p is taken out one by one in the side direction, and the friction plate e for preventing double taking and the feed roller There is a structure in which the material is fed between the "f" and "f" and supplied to a downstream conveyance path (not shown).

However, in the past, the entire portion corresponding to the guide plate c for regulating the take-out position and the supply section a was flat, and paper sheets with folds were
When p' is located at the frontmost end, a gap g is created between this sheet p' and the take-out roller d, making it impossible to take out the paper. There was an inconvenience that the friction plates between the paper sheets p and between the paper sheets p became strong, making it impossible to take them out or causing many sheets to be taken out at the same time.

The present invention was developed based on the above-mentioned circumstances, and its purpose is to provide a paper sheet retrieval device that has an extremely simple structure and is capable of reliably retrieving even folded sheets. This is what we are trying to provide.

Hereinafter, the present invention will be explained with reference to an embodiment shown in FIGS. 2 to 4. In the figure, reference numeral 1 denotes a supply section that can collectively supply a large number of paper sheets p... that are superimposed in the plane direction. It is held by the backup body 4 in an upright position with its side in the take-out direction in contact with a side guide plate 3 erected on the substrate 2.
Furthermore, the paper sheets p... are pressed in the plane direction by the backup body 4 and urged toward the guide plate 5 for regulating the take-out position, and the frontmost paper sheets p are formed on the guide plate 5. It is pressed against a take-out roller 7, which has a portion thereof projected through a roller projection window 6.

Then, by driving the take-out roller 7 counterclockwise, the paper sheet p at the forefront is taken out in the side direction, that is, in the left direction in the figure, and the paper sheet p is taken out by the feed roller 7.
and a friction plate 9 for preventing double-sheet taking that contacts the feed roller 8 with an appropriate pressure, and is then delivered to a conveyance path 12 formed by the mutually opposing surfaces of the conveyor belts 10 and 11. It's summery.

In addition, the above-mentioned take-out roller 7 and feed roller 8
are rotatably supported by shafts 7a and 8a, as shown in detail in FIG. There is. Furthermore, the drive gear 13
is fitted onto a drive shaft 18 which is interlocked with a motor 17 as a drive source via a transmission mechanism 16 such as a pulley or belt. When the motor 17 is driven, the take-out roller 7 and the feed roller 8 are simultaneously rotated counterclockwise, and when the motor 17 is stopped, the rotation of the rollers 7 and 8 is simultaneously stopped.

Further, the guide plate 5 for regulating the extraction position is
The portion 5a located on the side opposite to the take-out direction from the take-out roller 7 is shaped so as to escape outwardly so as to be separated from the frontmost sheet p in the supply section 1, and the guide plate 5 and the sheet p , it is possible to reduce the frictional resistance between the paper sheets p and the paper sheets p, and moreover, as shown in FIG.
It is designed to come in contact with

Note that 19 shown in FIG. 2 is a paper sheet detector placed at the starting end of the conveyance path 12, which detects the leading edge of the paper sheet p carried in and detects the following paper sheet p. It is designed to control the timing of take-out.

Therefore, the paper sheet group p supplied into the supply section 1
Even if the paper sheet p' has a crease, it will surely be taken out one by one starting from the frontmost one.

As explained above, according to the present invention, the portion of the guide plate for regulating the take-out position, which is located on the side opposite to the take-out direction from the take-out roller, is released outward so as to be separated from the foremost sheet in the supply section. Although it has a simple configuration, it has the effect that even folded paper sheets can be taken out one by one with certainty.

Claims (1)

[Claim for Utility Model Registration] In a device in which the frontmost paper sheets are sequentially taken out in the side direction one by one as the take-out roller 7 rotates, the paper sheet is removed from the take-out roller of the take-out position regulating guide plate 5. A paper sheet retrieval device characterized in that a portion 5a located on the retrieval direction side is configured to escape outward so as to be separated from the foremost sheet in the supply section.
