Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a paper sheet bundling device for bundling paper sheets formed by stacking paper sheets such as banknotes.

[Conventional technology]

In general, this type of paper sheet bunching device inserts the paper sheet between a pair of spaced apart and opposing clamp plates, holds the paper sheet under pressure by these clamp plates, and then applies a tightening device such as a clamping member to the paper sheet group. The tape is wound and bundled.

By the way, if the paper sheets are simply wound with a tape in a normal state, it is difficult to tightly bundle the paper sheets. Therefore, in the past, it has been considered to use a clamp plate, as disclosed in Japanese Patent Application No. 51-47211, to enable firm clamping. That is, as shown in FIG. 5, the clamp plate a is formed into a dogleg shape.
By pressing the paper sheet group b, the paper sheet group b
The tape is folded into a dogleg shape, and the folded sheet group b is returned to its initial state, thereby applying tension to the tape and tightly binding the sheet group.

[Problem that the invention seeks to solve]

However, in the conventional type, the clamp plate itself was formed into a dogleg shape, so if the width of the separation between the clamp plates was not made large, the paper sheets would come into contact with the center of the clamp plate when inserting the paper sheets, making it easy to insert them. Furthermore, when the clamp plate is placed in a horizontal position, the upper or lower sides of the sheets come into contact with the center of the clamp plate, making them easy to turn over.

The present invention has been made focusing on the above circumstances,
The object thereof is to provide a bundled device for paper sheets that is capable of folding paper sheets into a dogleg shape without forming a clamp plate into a dogleg shape.

[Means for solving problems]

In order to achieve the above object, the present invention clamps and holds a group of paper sheets by a pair of spaced apart and opposing flat clamp plates, and bundles the group of paper sheets by rotating them by the revolution of a bundler. The invention includes a lever that is operated when the bundler revolves and presses one end of the group of sheets held under pressure by the clamp plate to form a dogleg shape.

[Effect]

By holding a group of paper sheets under pressure with a clamp plate and pressing one end of the group of paper sheets with a lever,
To bend a group of paper sheets into a dogleg shape without forming a clamp plate itself into a dogleg shape.
