FIG. 4 shows an example of a binding device. In the figure,
A binding arm 52 is rotatably provided at one end of the base 51, and a holding device 53 for holding the cut end of the binding tape T and an object to be bound are placed at the other end of the base 51. It has a mounting table 54, a manual handle 55 that presses the objects W to be bound onto the mounting table 54, and a bundling means 56 that converges and aligns the objects W that are interlocked with the manual handle 55.

The binding work using this conventional binding device is
First, the object W to be bound is brought into contact with the tensioned part of the binding tape T that is guided by the binding arm 52 and extends from the binding arm 52 toward the holding device 53, and while the binding tape T is pulled out, the object to be bound is placed on the mounting table 54. Then, by operating the manual handle 55, the bundled objects W placed on the mounting table 54 are bundled by the bundler 56, and then the binding arms 52 are tilted and bound. The binding tape T is wound around the object W.

[Problem to be solved by the invention]

However, as described above, since the placing operation of the objects W to be bound and the binding operation are separate, the operator's hands are required in many places, making the binding work troublesome.

Moreover, in the conventional binding device, after the binding of the objects to be bound is completed, the manual handle 55 must be operated to release the binding, which makes the binding work even more troublesome.

The present invention has been made in view of the above-mentioned drawbacks of the prior art, and an object of the present invention is to provide a series of operations including placing an object on a mounting table and raising and lowering a binding arm. An object of the present invention is to provide a bundling device that can perform bundling work.
