The holes are continuously drilled from the groove 234 to the outermost part of the large flange 213, and are provided radially in three places on the large and small flanges in the groove 234, and on the curved surface part 216 of the cylindrical part 215 divided into three parts. There will also be separate locations for each.

Therefore, the small flange 211, the cylindrical portion 215, and the large flange 2
13 are combined to form the take-up ribbin 210, three continuous grooves are formed at equal intervals. Further, the cylindrical portion 215 is provided with a plurality of grooves 237 having unequal widths in the curved surface portion 216, and these grooves are used to fold the wire by the device of the present invention before starting to wind the winding wire onto the winding bobbin. This serves to hook the curved end.

Further, the groove 234 is for locking a binding wire.
Next, the operation of the threading device of the present invention will be explained in relation to the threading process of the binding machine.

First of all, the initial threading work is done by hand. By hand, the wire 50 is pulled out from the wire bobbin 501, passed through the adjustment roller 503 of the shaping plate 504, and then placed in the chuck 51.
The lower block 533, presser bar 535, and cutting member 536 are located below the upper block 532 when the opening/closing arm 523 is in the open state and the cutting/folding device 530 is in the open state before operation. After passing through the gap formed during the winding process, the end of the wire 50 is bent into a 7-shape, and this 7-shape is pushed into one of the grooves 237 formed in the winding bobbin 210, so that the wire 50 is wound. When mounted tightly on the cylindrical portion 215 of the take-up bobbin 210, the take-up bobbin 210 is rotated by a known drive mechanism (with its speed initially adjusted), and continues to pull the wire into the cylindrical portion 215. When a predetermined number of windings is reached, the rotation of the winding bobbin 210 is stopped and the winding bobbin 210 is stopped at a predetermined position. At the same time, the chuck 511 operates to clamp the wire 50. The details of its operation are as follows. The cylinder 514 provided on the chuck 511 operates, and the cylinder rod 527 moves forward, and the pair of opening/closing arms 523
opens outward around the pin 524, and the beak-shaped ends 523'', 5.23'' of the pair of opening/closing arms 523 close inward to clamp the wire 50. In this way, the wire 50 is installed between the chuck 511 and the winding bobbin 210. Next, the cutting and bending device 530 is operated to cut and bend the wire rod 50 that has been tensioned as described above, and the details thereof are as follows.

First, the presser bar 535 of the cutting and folding device 530 is
44, the end of which pushes up the wire 50 from its lower surface and brings it into contact with the lower surface of the upper block 532, and almost at the same time when the wire 50 is held between both members, the lower block 533 and The cutting member 536 is connected to the cylinder 531, which is a driving device, and the rod 5 connected thereto.
34 and by the action of the drive device 545, the wire 5 rises.
0 is pushed up from its lower surface and brought into contact with the lower surface of the upper flock 532.

At this time, the upper end of the lower block 533 and the upper end of the tongue 540 of the cutting member 536 only push up and hold the wire 50 onto the lower surface of the upper block 532, but the cutting edge 548 and the inclined surface 549 of the cutting member 536 The breaking edge 548 enters into the hollow part 552 of the upper block 532, and cooperates with the cutting edge 546 of the upper block to shear the wire 50, and at the same time cuts the inclined surface 549 of the lower block and the inclined surface 5 of the upper block.
47 press against the wire rod 50 and come into contact with each other, so that the wire rod 50 is bent into a wedge shape along the inclined surface. Next, presser bar 5
35 is lowered by the operation of the drive device 544, the bending rod 538 is lowered by the operation of the drive cylinder 537 and inserted into the hollow part 551 so as to follow this.

Therefore, the end of the wire 50 held between the upper end of the lower block 533 and the lower end of the upper block 532 is bent downward to form a U-shape. After that, the lower block 533,
Since the cutting member 536 as well as the bending rod 538 return to their original positions by the action of their respective actuators, the cutting and bending device 5
30 is in an open state before operation, and the wire rod 50 with its end bent remains supported by the chuck 511).

Next, the chuck 511 is attached to the wire rod 50 which is bent downward into a U-shape.
is carried in a direction perpendicular to the axis of the winding bobbin 210, and its U-shaped end is hooked into the groove 237 of the winding bobbin.

The details are as follows. On the other hand, before the start of the hooking operation, the portion of the wire 50 whose end has already been cut and bent into an L shape by the cutting and bending device 530 is not wound up yet.
Winding bobbin 21 driven at low speed by a known drive device
It is gradually wound up to 0.

When the above-mentioned winding is completed, the turret disk 1 on which a plurality of winding bobbins are attached is rotated by a predetermined angle by a known rotary drive device. Moves to the next binding position, and instead, a new winding bobbin 210 with the binding wire attached moves to the threading position together with the turret disk 1, and stops at the same predetermined position as the previous winding bobbin. .
When the replacement new winding bobbin is stopped in place, the cylinder 519 of the chuck 511 begins to operate, advancing the rod 520 and pressing the lever 517.

Slide block 513 with chuck 511 on the top surface
The lever 517, whose notch 518 is fitted into the lever 515 provided in the
, the slide block 513 slides on the pair of guide bars 512 together with the chuck 511 holding the wire rod 50 with the bent end, and takes up the winding bobbin 210.
A plurality of grooves are formed in the axial direction in the cylindrical body 215 of the winding bobbin 210, which moves in a direction perpendicular to the axial direction of the winding bobbin 210, and at the terminal end, the U-shaped end of the wire rod 50 is newly moved and stopped at a predetermined position. Hook it on one of 237. Next, the winding pushing member 5
The cylinder 563 of 60 operates, the rod 564 moves forward, and the pushing member "50 is wound up into the cylindrical part 2 of the bobbin 210.
Press in 15 directions.

The pushing member 560 rotates about the shaft 561 and descends, and with its flat lower surface, the bent end of the wire that has already been hooked into the groove 237 of the winding bobbin 210 due to the action of the chuck 511 is pressed. The bent end is press-fitted into the groove 237 so that it does not fall off. As described above, the bent end of the wire 50 is wound up into the groove 2 of the bobbin 210.
At the same time as the attachment to the chuck 511 is completed, the cylinder 514 provided on the chuck 511 retreats, and the a cylinder rod 527,
When the end 523'' of the opening/closing arm 523 is opened via the movable arm 528 and the swinging piece 525 and the wire 50 is released, the lever 518 operates in the completely opposite manner to the above, and the chuck 51
1 and return to the original position.

The wire rod pushing member 560 also returns to its original position as the rod 564 retreats due to the operation of the cylinder 563.

Next, the winding bobbin 210 starts rotating by a known drive device, and after the wire is wound in an aligned manner around the bobbin a predetermined number of times, the bobbin stops at a predetermined position.

Then, as mentioned above, cutting and bending using a cutting and bending device,
The conveyance and hooking of the wire by the drawing device, and the locking of the end of the wire to the winding bobbin by the wire pushing member are repeatedly and automatically performed. As described above, according to the wire threading device of the present invention, in the step of threading the wire drawn from the strand bobbin onto the winding bobbin, the drawing device performs the work of drawing out the wire and the work of hooking it onto the winding bobbin. The cutting and bending device can automatically and efficiently cut and bend the end of the wire, and the wire pushing device can automatically and efficiently lock the end of the wire into the groove of the winding bobbin. It must be said that this is an extremely useful invention.
