And tension is applied to the strip. After the feeding operation is completed, when the belt-shaped material is fed out by the roll rotating means, the tension roller is returned to the standby position by the urging means. Then, when the tension roller returns to the standby position, the tension acting on the strip is released by the release means. Alternatively, at the time when the tension roller returns to the standby position, the belt-shaped material is further fed out by the roll rotating means and loosened around the tension roller, so that no tension is applied.

As described above, when the belt-shaped material is supplied, the tension roller applies a predetermined tension to the belt-shaped material to absorb the slack, and the belt-shaped material is not tensioned during standby. Thus, even when the standby state is maintained for a long time, it is possible to suppress the deformation and the curl of the belt-shaped material. Therefore, it is possible to prevent the leading end of the strip from entering between the end of the guide passage and the binding portion, or from being rolled inward in the guide passage, thereby preventing the feed from being performed, thereby enabling stable supply of the strip. Become.

When a band feed signal is input from the control unit at the time of band supply, the band feed motor 354a is normally driven at a predetermined speed for a fixed time. Thus, the band material B is sent out to the band feeding device 28 by a predetermined amount by the first and second feed rollers 356a and 358a. In FIG. 7, the length of the band-shaped material B interposed between the first band roll RA and the first feed roller 356a is set substantially equal to the length required for one binding operation.

As shown in FIG. 9, when the belt-shaped material B is sent out, the belt-shaped material B which has been loosely positioned around the tension roller 384a is wound around the tension roller 384a. During this time, the belt-shaped material B is guided by flanges 385 provided at both ends of the tension roller 384a, and is fed without coming off the tension roller. And
When the belt material B is further fed, the tension roller 38
4a is pulled by the band material B to apply tension to the band material, and the tension arm 382a rotates clockwise from the standby position against the urging force of the tension spring 388a. Thereby, the detection protrusion 390a of the tension arm 382a is separated from the arm sensor 392a,
The arm sensor 392a outputs a bright signal.

The controller sends the band feed motor 354 a predetermined time after receiving the bright signal from the arm sensor 392a.
The driving of d is stopped. As a result, the band material B necessary for one bundling is supplied from the band supply device 300 to the band feeding device 28.
Supplied to

The controller stops the driving of the band feed motor 354d and simultaneously drives the roll drive motor 338a to rotate normally at a constant speed. Thereby, the first band roll RA is rotated at a constant angular speed in the counterclockwise direction, and the band material B is fed out from the outer periphery thereof. Then, the tension roller 3
The tension arm 84a and the tension arm 382a are rotated counterclockwise by the tension spring 388a and return to the standby position.

When the tension arm 382a returns to the standby position, the arm sensor 392a detects the detection protrusion 390a and outputs a dark signal. Then, after receiving the dark signal, the control unit controls the roll drive motor 338a for a certain period of time.
Is continuously driven to feed out the band material B from the first band roll RA, and then the roll drive motor 338a is stopped. As a result, as shown in FIG. 7, the belt-shaped material B is fed out by a predetermined amount in a state of being slackened around the tension roller 384a, so that the tension is released and the belt-shaped material B is engaged only with the upper surface side of the tension roller. .

Thereafter, the band supply device 300 is maintained in the state shown in FIG. 7 until the next band feed signal is input from the control unit. Accordingly, no tension is applied to the belt-shaped material B on standby. In the stopped state, the roll drive motor 338a is in a state where the brake is applied by its own excitation torque.

According to the band feeding device of the binding device configured as described above, the band is fed out even after the band feeding is completed and the tension roller returns to the standby position, and the band is loosened around the tension roller 384a. , The tension can be applied to the belt-shaped material B during standby. Thereby, even when the belt-shaped material B is maintained in the standby state for a long time, it is possible to suppress deformation of the belt-shaped material and occurrence of curl. Further, at the time of supplying the band material, the tension roller 384a applies a predetermined tension to the band material to absorb the slack, thereby preventing the band material from being caught or clogged. Therefore, it is possible to prevent the leading end of the strip from entering between the end of the guide passage and the binding portion, or from being rolled inward in the guide passage, thereby preventing the feed from being performed, thereby enabling stable supply of the strip. Become. As a result, the operating efficiency of the binding device and the processing device can be improved.

The present invention is not limited to the above-described embodiment, but can be variously modified within the scope of the present invention. For example, it goes without saying that the band supply device and the binding device according to the present invention can be applied not only to securities but also to the binding of other paper sheets. Further, in the band supply device, after the tension roller returns to the standby position, the belt roll is rotated for a certain period of time to loosen the shape material. The rotation time may be adjusted.

Further, the tension of the strip is released by increasing the amount of feeding of the strip and loosening it. However, the present invention is not limited to this, and the strip is fed until the tension roller returns to the standby position. Alternatively, the tension roller may be forcibly moved from the standby position to the feed side to release the tension of the strip.

[0075]

As described above in detail, according to the present invention, in the standby state, the belt is loosened to release the tension acting on the belt, so that the belt is deformed and curled. It is possible to provide a band feeding device of a paper sheet binding device capable of suppressing the occurrence of the like and stably feeding the band material.
