Description

TECHNICAL FIELD The present invention relates to a device for supplying a binding tape in a banknote binding machine for bundling accumulated banknotes with a binding tape, and particularly to reduce abrasion of rollers for feeding the binding tape. The present invention relates to a binding tape feeding device in a bill binding machine with an improved life.

"Prior Art" Conventionally, as a device for binding stacked banknotes, Japanese Patent Laid-Open No. 61-
A device as described in 203320 is known.

This is equipped with a bundling tape feeder having a pair of rollers for holding and feeding the bundling tape, and in order to tightly bund the banknotes, the stacking banknotes and the leading ends of the bundling tapes are stacked with strong force. The bills are rotated, and a braking force is applied to the feeding of the binding tapes so that the binding tapes are wound around the stacked bills while being tensioned.

As means for applying a braking force to the feeding of the binding tape, the motor for driving the roller is stopped and the rotation of the roller is restrained to generate a frictional force between the roller and the binding tape. The method of making this act as a braking force was taken.

"Problems to be solved by the invention" However, as a material of the roller, a material having low abrasion resistance such as rubber must be used for the purpose of ensuring the feeding of the binding tape, so the binding tape is fed out. In the above-mentioned conventional device that applies a braking force to the binding tape by the friction of the roller, the supply roller may be worn out early due to this friction, causing a malfunction.

That is, the roller may be worn and its peripheral surface may become distorted, so that the binding tape may not be reliably fed or may be fed obliquely. For this reason, the service life of the bundling device with high reliability has been extremely short due to the early wear of the roller.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a binding tape feeding device in a banknote binding machine, in which a roller for feeding the binding tape is less likely to be worn.

"Means for Solving the Problem" The binding tape feeding device in the banknote binding machine of the present invention is
At least a pair of rollers for feeding the binding tape by gripping and moving it, and a brake mechanism that is provided separately from the rollers and applies a braking force with a friction member while allowing the relative movement of the binding tape, and the operation of the braking mechanism. And an interlocking mechanism for interlocking the rollers with each other so as to separate the rollers from each other.

[Operation] According to the binding tape feeding device in the banknote binding machine of the present invention, if the brake mechanism is operated when the binding tape is wound, the braking force is applied to the binding tape by this, while the interlocking mechanism causes the braking force to increase. Since the rollers are separated from each other in synchronization with the operation, the life of the bill binding machine can be significantly improved.

That is, when the braking force is applied to the binding tape, the frictional force between the roller and the binding tape is surely prevented from acting, so friction is required to ensure the delivery (in other words, wear resistance The roller only rolls when the binding tape is paid out, so
Premature wear of the rollers is reliably prevented. on the other hand,
The friction member of the brake mechanism provides tension to the binding tape, and does not require the frictional property of the roller that feeds the binding tape. Therefore, a material having high wear resistance can be used and wear can be prevented. Therefore, early wear of the members is prevented as a whole, and the operation of supplying the binding tape or the operation of applying the braking force to the binding tape is ensured in the long-term use, and the bill binding machine is highly reliable. The operating life is greatly improved.
