JPH02100933A - Separation/feed mechanism for sheet paper or the like - Google Patents

Abstract

PURPOSE:To eliminate the occurrence of discharging multiple sheets and the impertinent motion of a roller and make the paper feed without an oblique movement possible by forcing the top end of a bundle of paper in sheets to proceed along a guide plate with a carrier belt. CONSTITUTION:By a shaft 2 rotated in the direction indicated by A, an extruding rubber 3 mounted to an extruding roller 1 extrudes a bundle 5 of paper in sheets supported by a presser plate 4 to the side of a flaking roller 6. A shaft 7 and 2 synchronously rotate in the direction indicated by A. A rubber roller 8 that does not rotate performs the separation and extrusion together with a flaking roller 10. The upper end of the bundle 5 of paper in sheets is pressed down by a carrier belt 11 and turns in the direction indicated by B when a pulley 12 is rotated, and in addition, as a pulley 13 is energized to the side of the flaking roller 6 by a spring 14, the bundle of paper in sheets proceeds along a guide plate 15, and forms the shape of the point of a sword between the flaking roller 6 and the rubber roller 8.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a paper sheet separation and feeding mechanism that separates paper sheets such as banknotes accumulated in a bundle one by one.

[Conventional technology]

Conventionally, in this type of paper sheet separation/feeding mechanism, as shown in FIG. A single bundle of paper leaves is aligned along a guide plate 22 to form a sword tip shape, and a peeling rubber 21 attached to a peeling roller 20 that rotates in the C direction and a rubber roller 2 that does not rotate are attached.
3, the paper sheets were peeled off one by one and discharged to the paper sheet conveying device following the paper separation and feeding mechanism.

[Problem to be solved by the invention]

In the above-mentioned conventional paper sheet separation and feeding mechanism, the paper sheet stack does not follow the guide due to variations in the coefficient of friction between the sheets in the paper sheet bundle set in a box shape, so the tip shape cannot be formed neatly. This method has disadvantages in that errors in peeling the paper sheets occur, resulting in multiple sheets being ejected, rollers oscillating in vain, and slanting ejection.

[Means to solve the problem]

The paper sheet separation/feeding mechanism of the present invention includes: an extrusion roller that pushes out the negative side of a bundle of paper sheets toward the leading end; a presser plate that presses and holds the bundle of paper sheets against the extrusion roller; and the extrusion roller. a peeling roller that sends out the sheets of the bundle of sheets one by one through fixed rollers; a guide plate that guides the leading end of the bundle of sheets to the peeling roller; and a conveyor belt that presses the rear end toward the leading end to form a sword-point shape at the leading end of the bundle of sheets along the guide plate.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a side view of one embodiment of the present invention. The extrusion roller 1 is connected to the shaft 1, and the shaft 2 is
By rotating in the direction, the extrusion rubber 3 attached to the extrusion roller 1 extrudes the paper bundle 5 held on the presser plate 4 toward the peeling roller 6 side. The peeling roller 6 is attached to the shaft 7
The shirts 1 to 7 and the shaft 2 are connected to a bell 1 (not shown), etc., and rotate synchronously in the A direction. The rubber roller 8 is connected to one shaft, but since the shaft 9 is fixed, the rubber roller 8 does not rotate, and is separated and discharged by the release rubber 10 attached to the release roller 6 and the rubber roller 8.

The upper end of the bundle of paper sheets 5 is held down by a conveyor belt 11, and the conveyor belt 11 is connected to a pulley 12. It depends on pulley 13.

When the pulley 12 is rotated, the conveyor belt 8 rotates in the direction B, and since the pulley 13 is urged toward the peeling roller 6 by the spring 14, the bundle of sheets follows the guide plate 15 and passes through the peeling roller 6 rubber roller 8. Since it forms a beautiful tip shape between the edges, it is easy to peel it off and there is no skewing of paper sheets.

〔Effect of the invention〕

As explained above, in the present invention, by forcibly aligning the leading edge of a bundle of paper sheets along a guide plate using a conveyor belt, it is possible to reliably form a sharp tip shape that is easy to peel. Paper feeding without skewing is possible without causing miss-feeding.
