Abstract

PURPOSE:To provide a binding device which, in binding piled sheets of paper o the like into a bundle, enables the ends of a binding band to be spliced always at a fixed position independent of the thickness of the object to be bond and ensures a good invariable quality of the binding. CONSTITUTION:The time taken for a sensor 30, after the start of the actuation of a compression board 2, to detect the farthest end of one batch of piled sheets of paper A is converted by calculation into a thickness of the pile of paper A. On the basis of this result, the operation of a band-feeding mechanism 10 is so controlled as to have the back end of the binding band 8 at a specific position on the bond bundle A and the actuation of a cutting mechanism 15 is also controlled. Therefore, in forming bundles of piled sheets of paper A or the like, the ends of the binding band can be spliced always at a fixed point independent of the thickness of the bond object.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet group binding device for binding paper sheet groups such as stacked banknotes.

[0002]

2. Description of the Related Art A conventional binding device of this type is constructed by binding a binding band of a constant length without measuring the thickness of a sheet group before binding. However, in the case of stacking paper sheets, if the stacking amount is large, even if the number of sheets is the same, the thickness thereof will vary considerably.

[0003]

Conventionally, regardless of the difference in the thickness of the paper sheet group, the binding band of a constant length is used for binding, so that the bonding position of the band ends during binding is not stable. However, there is a problem in that the quality of the binding varies.

The present invention has been made based on the above-mentioned circumstances, and the bonding positions of the band ends at the time of bundling can always be made constant, irrespective of the difference in the thickness of the paper sheet group to be bound. An object of the present invention is to provide a bundling device for a paper sheet group capable of maintaining the bundling quality of the above.

[0005]

In order to solve the above problems, the present invention provides a stack of paper sheets having a fixed plate and a compression plate movably in the fixed plate direction between these two plates. A compressing means for compressing, a strap supplying means for supplying a strap for binding the paper sheets compressed by the compressing means, and a strap provided on the fixing plate portion and supplied by the strap supplying means. A band pressing member for pressing the front end portion between the sheet group and the paper sheet group, and a guide member for guiding the middle portion of the binding band whose front end portion is pressed by the band pressing member are provided along with the rotation of the guide member. And band cutting means for winding a binding band around the compressed paper sheet group, and band cutting for cutting the binding band provided near the binding band feeding direction by the band feeding means to a predetermined length. Means and this band cutting means And a sealing means for pasting the end portion of the binding band onto the binding band wrapped by the banding means, and a certain distance from the fixing plate, which is moved to the fixing plate side by the compression plate. Detecting means for detecting the position of the outermost end of the paper sheet group, and the binding band for converting the thickness of the paper sheet group from the time from the start of the compression plate to the detection of the position of the outermost end portion of the paper sheet group by the detecting means. Is provided with control means for controlling the feeding operation of the band feeding means and the cutting operation by the band cutting means so that the end part of the band comes to a predetermined position of the paper sheet group.

[0006]

In the bundling device of the present invention, the thickness of the sheet group is converted from the time from the start of the compression plate to the detection of the position of the outermost end of the sheet group by the detection means, and the end portion of the bundling band is calculated. By controlling the feeding operation of the band feeding means and the cutting operation by the band cutting means so as to come to a predetermined position of the paper sheet group, the band end at the time of binding regardless of the difference in the thickness of the paper sheet group. The laminating position can be always constant.

Further, a cutter mechanism 15 as a band cutting means for cutting the binding band 8 into a predetermined length is provided near the feeding direction of the binding band 8 by the band feeding mechanism 10.

The cutter mechanism 15 has a movable blade 17 and a fixed blade 18 which are driven by a solenoid 16, and the movable blade 17 is moved in the direction of the fixed blade 18 by the operation of the solenoid 16 to cut the binding band 8. It is supposed to do.

Further, in the vicinity of the fixed plate 1, a band pressing plate as a band pressing member for pressing the tip end of the binding band 8 supplied by the band supply mechanism 10 so as to sandwich it with the paper sheet group A. 20 are provided.

Further, a guide plate pair 21 is provided as a guide member for guiding the middle portion of the binding band 8 whose tip is pressed by the band pressing plate 20, and is compressed as the guide plate pair 21 rotates. A strapping mechanism 22 as a strapping means for winding the binding strip 8 around the paper sheet group A is provided. The guide plate pair 21 is held at the tip of an arm (not shown) that turns using the strapping motor 23 as a drive source. And,
The binding band 8 is wound around the paper sheet group A by turning the paper.

Also, above the fixed plate 1 and on the guide plate pair 2.
On the outer side of the movement locus of 1, the band end (end part) of the binding band 8 cut by the cutter mechanism 15 is connected to the band feeding mechanism 1

Sandwiched between and.

After the compression is completed, the strapping motor 23 of the strapping mechanism 22 is driven, and the guide plate pair 21 attached to the tip of an arm (not shown) sandwiches the binding strip 8 in the direction of arrow c. Start spinning. Then, it pauses at the position shown in FIG.

On the other hand, the control unit 31 converts the thickness of the paper sheet group A from the time from the start of the compression plate 2 to the detection of the position of the outermost end of the paper sheet group A by the sensor 30. Then, based on the conversion result, the drive roller 12 and the driven roller 13 of the belt feeding mechanism 10 rotate, the binding band 8 is further extended by a predetermined length, and then the movable blade of the cutter mechanism 15 is moved. 17 moves in the direction of arrow d in FIG. 2 to cut the binding band 8. As a result, the binding band 8 has such a length that the band end (end part) to be thermocompression bonded comes to a predetermined position of the paper sheet group A.

After the band is cut by the cutter mechanism 15, the guide plate pair 21 of the band hanging mechanism 22 starts to rotate again, and after making one round, the binding band 8 is wound around the sheet group A, as shown in FIG. Then, the heat block 27 of the thermocompression bonding mechanism 25 descends in the direction of arrow e to bond the band end portions, and the bundling is completed.

Before the binding band 8 is cut, the band feeding mechanism 1 is operated while the guide plate pair 21 of the band hanging mechanism 22 is rotating.
The rollers 12 and 13 of 0 are rotated in the direction of feeding the binding band 8, and even if a narrow paper band whose strength is weaker than the conventional one is used as the binding band 8, stable binding without band breakage or the like. You can do it. The present invention is not limited to the above-described embodiment, and it goes without saying that various modifications can be made without departing from the scope of the invention.
