Description

Description: BACKGROUND OF THE INVENTION The present invention relates to an apparatus for separating paper sheets, and is particularly suitable for separating paper sheets having low rigidity or paper sheets having a wrinkled deformation at the tip. About the guide.

[Conventional technology]

In the conventional apparatus, as described in JP-A-59-72590, a separating section for bills, such as paper sheets, is a feed roller and a gate roller for separating bills one by one, and guides bills to the feed roller and the gate roller. The guide is planar so as not to be particularly deformed in the width direction of the bill so as to enter between the feed roller and the gate roller in a uniform state without deformation in the width direction of the bill. Was configured to.

[Problems to be solved by the invention]

According to the above-mentioned conventional technology, a sheet having low rigidity, or a sheet having curled wrinkles at the front end collides with a stationary gate roller at the front end to buckle, jam or separate obliquely. No consideration has been given to preventing
There was a problem with the reliability of the device.

SUMMARY OF THE INVENTION It is an object of the present invention to separate sheets without buckling even when the sheets collide with a gate roller, and to prevent jamming or skewing.

[Means for solving the problem]

The above object is achieved by providing a guide for bending and deforming the sheet in the width direction of the sheet so that the sheet does not easily buckle even if the sheet collides with the gate roller. You.

[Action]

That is, paper sheets whose initial shape is curled, or
If the wrinkled paper sheet enters the separation section as it is, it may cause a jam when it collides with the gate roller.However, if the paper sheet is bent and deformed in the width direction of the paper sheet by the guide, the paper sheet may be damaged. Not only is the leading end straightened in the traveling direction of the paper sheet, it becomes difficult to collide with the gate roller, but even if it collide with the gate roller, the buckling strength is increased, so that it is less likely to buckle. Accordingly, it is possible to prevent a jam or a skew due to buckling at the separation portion, and thus it is possible to improve the reliability of the device.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS.

7 is a storage box for storing the deposited bills, 12 is the deposited bills, 1 is a pick-up roller, a plurality of which are rotationally driven by a driving source (not shown) and are arranged at intervals in the axial direction, and 2 is a belt 3 A feed roller that rotates in synchronization with the pick-up roller 1 and a gate roller that is stationary and located at a position axially displaced from the aforementioned feed roller 2 and a part of the circumference of each other overlaps between two adjacent feed rollers 2. Are arranged as follows. 5 is a paper sheet having irregularities (5a, 5b) in the width direction of the paper sheet (direction perpendicular to the paper surface of FIG. 1) which is a direction perpendicular to the traveling direction of the paper sheet to be separated and conveyed. A guide 6 having a concave-convex shape at a position facing the above-mentioned guide 5 and a guide for paper sheets having a concavo-convex portion with the guide 5, a press plate 8 for mounting the stacked paper sheets,
9 is a spring for pushing up the push plate 8 upward, 10, 15
Is a belt, and 14 and 16 are rollers driven by a driving source (not shown).

 With the above configuration, the following operation can be performed.

The stacked paper sheets 12 are pushed upward together with the pressing plate 8 by the spring 9, and the topmost paper sheet 11 of the stacked paper sheets 12 comes into contact with the pick-up roller 1. When the pickup roller 1 is rotated in this state, the uppermost sheet 11 is fed between the feed roller 2 and the gate roller 4 by the frictional force of the pickup roller 1. In this case, paper sheets
Numeral 11 is fed between the feed roller 2 and the gate roller 4 while bending and deforming between the upper and lower guides 5 and 6 having the corrugated shape in conformity with the guide shape. The feed roller 2 rotates in synchronism with the pick-up roller 1 and feeds the paper sheet 11 having entered between the running belts 10 and 15. Although not shown, the gate roller 4 plays a role of stopping the conveyance of the paper sheet on the side of the gate roller 4 when the paper sheets happen to be overlapped and enter between the feed roller 2 and the gate roller 4. I have.

 The following effects are produced by the above operation.

The stacked paper sheets can be separated one by one, and even if the leading end of the separated paper sheet 11 is curled in a direction in which it can easily collide with the gate roller 4, it can be bent and deformed by the guides 5 and 6. The curl is corrected so that the paper sheet 11 is deformed in a direction not to collide with the cage roller 4 and becomes difficult to collide with the gate roller 4, and at the same time, is bent and deformed. The buckling strength of the leaf 11 is improved, and there is an effect of preventing skewing of the paper leaf caused by buckling of a jam or a part of the paper leaf caused by buckling of the paper leaf.

FIG. 3 shows another embodiment of the present invention. In the embodiment of the present invention, instead of the guide 5 shown in FIGS. 1 and 2, a roller which is rotatable or driven by a driving source (not shown) is used.
The roller 13 is located at a position where the guide 6 is concave toward the roller 13. Thereby, the paper sheet 11 is separated between the feed roller 2 and the gate roller 4 while being bent and deformed, and the transport resistance can be reduced. Therefore, in addition to the effects of the invention described above,
Since the transport resistance can be reduced, the sheets can be hardly buckled. Further, when a conveying force is applied to the roller 13, there is an effect that the paper sheet is more difficult to buckle.

〔The invention's effect〕

According to the present invention, it is possible to prevent paper sheets to be separated from collapsing with the gate roller to cause a jam or skew, thereby improving the reliability of the apparatus.
