Abstract

PURPOSE:To permit automatic rewinding of an electric wire by means of simple constitution by providing a rewinding arm which is equipped with a rewinding bar at a top edge and is turnable and shiftable in the vertical and horizontal directions, for an apparatus with which the electric wire is wound-up laternately onto a pair of bobbins. CONSTITUTION:When winding-up of an electric wire 16 onto a bobbin 8A is completed, a rewinding arm 27 is lowered together with an installation board 25, and the extension part of the electric wire 16 is hooked by the top edge part of a rewinding bar 27b. After the rewinding bar 27b is a little turned in this hook state, the rewinding arm 27 is shifted from a bobbin 8A side to a side 8B by transferring the second movable board 23. Then, the electric wire 16 is wound up in several turns in double state onto the vacant bobbin 8B by gradually elevating the installation board 25, turning the rewinding arm 27 on the vacant bobbin 8B side. In this case, the rewinding bar 27b is a little lowered midway, and a superposed part is formed on a rolled-up part. Then, the electric wire 16 between bobbins 8A and 8B is cut by a cutter 5, and rewinding is completed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a wire winding device which is arranged at a predetermined position q and facing each other at a predetermined interval in the front and rear direction. The present invention relates to a rewinding mechanism of a wire winding device configured to wind a wire around an empty bobbin and start winding onto the empty bobbin.

In a conventional wire winding device, the required amount of wire is wound onto a hobbin set in a predetermined position, and then the bobbin is replaced with another empty bobbin in the same position. You can either rewind the wire onto the bin, or set a pair of bobbins on a horizontal swivel plate, and after winding the wire on one bobbin, flip the swivel plate and wind the other empty bobbin in the same way. Take position iE
An IK was brought in and the wires were re-wound at this location, but in any case the re-winding of the wires had to be done manually and the work efficiency was poor.

The present invention provides a rewinding mechanism that allows rewinding of electric wire from a bobbin to an empty hobbin after winding is completed automatically without manual intervention. explain.

Hanging equipment 11
Bobbins 8A and U3, which are rotated by torque motors 7 and 7, are removably attached to both front and rear ends 1 of the shaft. As shown in FIG. 2, the y-end flange portion 3a of the support column 31d is fixed to the base 2 with bolts, and the center opening 4a of the horizontal support plate 4 is attached to the E end of the support column 3. The horizontal support plate 4 is fixed to the upper end of the support column 3 by welding or the like with the peripheral edge of the opening 4a supported by the flange 3bK of the support column 3, and the horizontal support plate 4 is fixed to the upper end of the support column 3. Rotating shaft 7 a #:l Protrudes toward the lower side through horizontal support plate 4 91, and a circular bobbin mounting 1+ is mounted on this protruding end.

By inserting several fret chucks 10 into the part and fitting the lower shaft hole 11 on the bobbin side into the fret chuck 10, each of the hobbins 8A and 8B is mounted on the bobbin mounting plate 9. This is a rod-shaped diameter expanding tool for forcibly fitting the conical end into the collet chuck 10 for 12 tons to fix the bobbins 8A, 8B.

The side cover 7bK of each torque motor 7 has a side opening 1.
3 is opened, and air from a blower 14 installed near this side opening 13 is sent into the cover 7b through the opening 13 so that the torque motor 7 can be cooled. In addition, as illustrated in FIG. 2, the UJ electric wire cutting tool 5 installed inside the column 3 has a lifting plate 5b equipped with a pair of scissor-shaped cutting blades 5a, 5a fixed inside the column 3. The cutting blade 5a is movable up and down by an electric cylinder 5cK, and the cutting blade 5a is at the highest position protruding from the opening 6 at the tenth end of the support 30 by means of a screw shaft 5d.

By closing 5a, the cutting action is performed at that position. Incidentally, the support column 3 is provided with an opening/closing door 15 through which the distribution line cutting tool 5 can be inserted or removed (see FIG. 1).

However, the electric wire 16 to be wound? As shown in FIG. 1, the windings rotate through pulleys 17A and 17B, respectively, and are wound onto the bobbin 8A on the first winding side. At this time, the pulley 17B is pivotally supported by the mounting member 1BDK, which moves up and down along the guy F column 18cK as the screw shaft 18B is rotated by the motor 18A.

It functions to reciprocate at a predetermined speed in the vertical direction so that the electric wire 16 is preferably wound around the bobbin 8A.
