Description

[Detailed Description of the Invention] In order to easily send the wire processed by an automatic wire processing device to the next process, it is necessary to wind the wire after processing into a coil of an appropriate diameter. The wire winding device has a drive shaft that supports a drive disk so that it can move back and forth and rotate, and a driven disk that is disposed on the extended axis of the drive shaft and faces the drive disk that moves back and forth. and a rotatably supported driven shaft, a drive device for forward and backward movement of the drive shaft, a drive device for rotation of the drive shaft, and an elastic material having wear resistance attached to the opposing surface of each of the disks, When the drive shaft advances and comes into contact with the elastic material of the drive disk, the wire supply pipe swings to follow the drive shaft and is held between the elastic material of the drive disk and the elastic material of the driven disk. and a brake device that releases the driven shaft only when the driven disc is pushed forward by the driving disc, and its purpose is to supply wire rods. Another object of the present invention is to provide an automatic wire winding device capable of automatically winding up, bundling and discharging the wire after winding.

The automatic wire winding device of the present invention includes a drive shaft supporting a drive disk so as to be able to move back and forth and rotate as described above, and a driven circle disposed on an extended axis of the drive shaft and facing the drive disk. A driven shaft supporting the plate so that it can move back and forth and rotate, a drive device for moving the drive shaft back and forth, a drive device for rotating the drive shaft, and a wear-resistant shaft attached to the opposing surface of each of the disks. When the drive shaft moves forward and comes into contact with the elastic material of the drive disk, it swings to follow the drive shaft and is clamped by the elastic material of the drive disk and the elastic material of the driven disk. A brake device that releases the driven shaft only when the driven disk is pushed forward by the drive disk, activates the drive device for forward and backward movement, and drives the drive disk. The shaft and the driving disk are moved forward, the elastic material of the driving disk is brought into contact with the elastic material of the driven disk, and the wire supply pipe is held between the elastic materials. is pushed forward by the continuously advancing drive shaft and drive disk, the brake device that was blocking the rotation of the driven shaft is released, and then the drive shaft is connected to the rotating drive device that is constantly rotating, and the drive shaft The driving disc, the driven disc, and the driven shaft are rotated to slide the elastic material of each of the discs against the wire supply pipe, while passing the wire from the wire supply pipe between the elastic members of each of the discs. Supply and wind up the wire.

When winding of the wire rod is completed, the drive shaft is separated from the rotation drive device, the drive shaft, the drive disk, the driven disk, and the driven shaft are stopped, and then the coil between the elastic members of each of the disks is The wire rods are tied together, and then the forward and backward drive device is activated to move the drive shaft and drive disk backward. At this time, the driven disk and driven shaft move back together with the drive disk and drive shaft, but when they move back halfway, the brake device is activated and stops, and then the drive disk and drive shaft move back further and the drive The elastic material of the disk is separated from the elastic material of the driven disk, and the bundled coiled wire falls downward and is discharged. Therefore, it is possible to automatically supply and wind up the wire, and to bundle and discharge the wire after winding.

Next, the operation of the automatic wire winding device will be explained.

First, operate the air cylinder 17 in the extension direction, and
9 and the link 20, the drive shaft 12 and the drive disk 16 are advanced to the left from the two-dot chain line position in FIGS. Even in this state, the drive shaft 12 and the drive disk 16 continue to move forward, so the wire supply pipe 30 is then swung to the left against the spring 32. Further, even after the elastic member 16a comes into contact with the elastic member 6a and the wire supply pipe 30 is clamped by the elastic members 16a, 6a, the drive shaft 12 and the drive disc 16 continue to move forward. and the follower shaft 5 are moved forward to the left against the spring 9 to separate the brake plate 7 from the brake plate 8. When this state is reached, the electromagnetic brake 21 is de-energized to allow the rotating bush 11 and the drive shaft 12 to rotate relative to the frame 3, and then the electromagnetic clutch 24 is energized to connect the rotary bush 11 and the V-pulley 26. Connecting. However, the same V
The pulley 26 is constantly rotating, and then the rotary bush 11, drive shaft 12, drive disk 16, driven disk 6, and driven shaft 5 rotate, and the elastic members 16a, 6a slide against the wire supply pipe 30. At this time, the electric wire is transferred from the extrusion device to the electric wire supply pipe 29.
, 30 to between the elastic materials 16a and 6a, but the above-mentioned The above-mentioned parts 8, 12, 16, 6, and 5 are rotated so that they match, and the electric wires from the electric wire supply pipes 29 and 30 are connected to the elastic material 16a.
, 6a. Further, when a predetermined length of the electric wire is supplied from the extrusion device, a cutter (not shown) is actuated by a signal obtained at that time, and the electric wire is cut. Further, each of the portions 8, 12, 16, 6, and 5 further rotates, and the cut portion (winding end) of the wire is wound between the elastic members 16a, 6a. Further, when the sensor 23 and the tab 22a detect a predetermined number of rotations, the signal obtained at that time is sent to the electromagnetic clutch 13 and the electromagnetic brake 21.
At the same time that the electromagnetic clutch 13 is de-energized and the connection between the rotary bush 8 and the pulley 1J26 is cut off, the electromagnetic brake 21 is energized and the rotary bush 11 is instantly fixed to the frame 3. Therefore, a notch 16 provided in the drive disk 16
b, 16b and the notches 6b, 6b provided in the driven disc 6 face horizontally. When this state is reached, a binding machine (not shown) is inserted into each of the notches 16b, 6b, and the elastic Both sides of the wire wound between the members 16a and 6a are tied together. Also, if this condition occurs, check the air cylinder opening in the retracting direction. Drive shaft 1 via screw 19 and link 20
2 and the drive disk 16 are moved back to the right. At this time, the driven disk 6 and the driven shaft 5 are connected by the spring 9 and the wire supply pipe 3.
0 retreats and swings to the right following the driving disc 16 by the spring 32, and when the brake plate 7 contacts the brake disc 8, the driven disc 6 and the driven shaft 5 stop retreating and are rotated. Fixed. However, since the drive shaft 12 and the drive disk 16 continue to move backward and the wire supply pipe 30 continues to swing, the elastic material 1
6a and the electric wire supply pipe 30 are separated from the elastic member 6a, and the electric wire wound up between the elastic members 16a and 6a falls in the direction of arrow A. Further, when the wire supply pipe 30 swings to the position indicated by the two-dot chain line in FIG. 4 and comes into contact with the stopper 32, the swing of the wire supply pipe 30 stops; continues, so the drive disk 16 separates from the wire supply pipe 30 and returns to the original state. One cycle of wire winding has been described above, and the same applies thereafter, and the wires are successively wound up to a predetermined length and sent to the next process. Although the present invention has been described above with reference to embodiments, it goes without saying that the present invention is not limited to such embodiments, and that various design modifications can be made without departing from the spirit of the present invention. .
