By the way, the to-be-bound object M which can be bound by using the conventional binding device is the first one.
The shape is limited to a shape that can be freely taken in and out of the space between the guide body 110, the second guide body 120, and the base 100. Therefore, for example, like the coil 220 protruding in a loop shape from the cylindrical motor iron core 210 as shown in FIG. 14, the motor iron core 210 interferes with the space between the second guide body 120 and the base 100. There is a problem that the binding process cannot be performed on the objects to be bound M that cannot be put in and taken out from the bundle.

In the conventional binding device, the pulling tool 130 is used.
When pulling the band-shaped piece of the binding band to tighten the binding band, the bound object M pulled by the binding band
Since the binding is performed without slack by pressing the sheet onto the base 100, the first guide body 110 and the second guide body 110 can be used as a bound body capable of surely binding without slack. Guide body 120 and base 1
It is required to be able to move freely in the space surrounded by 00 and. Therefore, unlike the coil 220 of FIG. 14, the motor iron core 210 is in the way so that it cannot move freely in the space surrounded by the first guide body 110, the second guide body 120, and the base 100. There has been a problem that it is difficult to perform binding without looseness on such a bound object.

The present invention has been made in view of this problem, and like the coil 220 shown in FIG. 14, since the iron core 210 is a hindrance, it cannot be bound by a conventional binding device. An object of the present invention is to provide a binding device capable of binding even a body. It is another object of the present invention to provide a binding device capable of securely binding a bound object fixed in a fixed position with a binding band without any movement of the bound object.

The strip-shaped piece 12 inserted into 30 reaches the guide passage 61 of the second guide body 6 while being deformed into a loop shape by the guide passage 51 of the first guide body 5, and further, the second guide body 6
It is guided downward in the drawing by the guide passage 61 and is inserted into the insertion hole 14 of the head portion 11 which is held in the accommodating space 46 in a positioned state. The tip portion 13 of the strip-shaped piece 12 thus inserted through the head portion 11 is taken in between the pair of rollers 76 and 77 of the pulling tool 7, and these rollers 76 and
The rotation of 77 pulls the strip 12. As a result, the radius of the loop of the strip-shaped piece 12 surrounding the to-be-bound body M becomes smaller, and the to-be-bound body M is bound by the binding band 1 while being fixed in a fixed position as shown in FIG.

After the bundle M is bound by the binding band 1 in this way, the excess portion 12a of the strip 12 is cut by the cutter 84 as indicated by arrow Z5 in FIG. This extra part 1
2 is then recovered.

When the series of binding steps described above are completed, the cutter 84 returns to its original state as shown in FIG. 21 to prepare for the next binding step.
