Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a winding device configured to wind a magnet wire by rotating the armature core or the like on which the winding is applied.

[Technical background of the invention]

Conventional winding devices keep the body to be wound stationary,
Generally, a so-called flyer from which the magnet wire is led out is rotated around the object to be wound, thereby winding the magnet wire around the object to be DIed in a relatively flank manner. And the winding Hii with this configuration! In this case, a mechanism for clamping the tip of the magnet wire prior to the start of winding is provided at a stationary part such as the base of the winding device.

By the way, in order to deal with slotted armature cores that require aligned winding of magnet wires due to the increased use of motors, the lead-out section from which the magnet wires are led out is kept stationary, and the wires to be wound are kept stationary. A winding ii has been considered in which the armature core side, which is the main body, is configured to rotate around the lead-out portion. In the winding device with this configuration,
If a separate device is provided on the base body to clamp the tip of the magnet wire 1 prior to the start of winding, as in the general winding device described above, after the start of winding, the portion clamped by the clamp I groove and ? l [The magnet wire between the parts wound around the child core is pulled by the rotational movement of the armature core, and
77FA occurs.

To prevent this, it is necessary to hold the tip of the magnet wire in a jig for fixing the armature core. Because it is configured to be removable for installation and removal, it is difficult to provide such a jig with a clamp mechanism that automatically opens and closes using a drive source such as an air cylinder. However, the winding must be manually held on the jig, which poses the problem that the winding cannot be fully automated.

[Object of the Invention] The object of the present invention is to provide self-opening/closing to a jig for removably fixing a wound body such as an armature core in a winding device in which the winding side is rotated. If possible, a lamp structure can be provided, and ll7 at the tip of the magnet wire.
An object of the present invention is to provide a winding device that can prevent ia and fully automate winding.

[Summary of the invention]

The present invention provides a jig with a clamp body which is biased in one direction by an elastic body so as to be movable in a reciprocating manner, a clamp body which is pressed against each other by the biasing force of the elastic body is formed on both sides, and a magnet wire is The magnet wire is characterized by being provided with an external deterrent that drives the clamp body against the biasing force of the elastic body to clamp the tip end of the magnet wire prior to winding, and releases the drive. be.

A mounting shaft portion 11 into which the bottle 3 is fitted is erected on the boss 1a. Reference numeral 4 designates a stopper pin fixed to the drive shaft 1 so as to fit into the small hole 2b of the electronic core 2 and prevent rotation thereof. Reference numeral 5 denotes a jig for removably fixing the armature core 2 to the drive shaft 1, and this jig 5 will be described in detail here.

That is, the jig 5 includes a central cylindrical shaft 7 having a substantially hook-shaped retaining groove 6, and a stepped cylindrical sleeve that surrounds the shaft 7 and has an upper end small diameter portion 8a fitted to the upper end of the cylindrical shaft 7. 8, and a fastening member 9, in which the sleeve 8 is fixedly tightened to the cylinder shaft 7 by screwing the male thread 9a to the female thread 7a at the upper end of the cylinder @7, is fitted to the lower part of the cylinder shaft 7 so as to be vertically movable. Supported cylindrical pressing member 10
and a compression coil spring 11 which is installed between the sleeve 8 and the presser member 10 and biases the presser member 10 downward. Incidentally, the portion where the sleeve 8 and the sleeve 8 meet is formed into a rectangular shape as shown by the broken line in FIG. 2 to prevent rotation. Reference numeral 12 designates an annular clamp body which is fitted and supported by the upper end small diameter portion 8a of the sleeve 8 so as to be able to reciprocate by rotation, and three projecting piece-shaped clamp portions 13 are provided on the outer periphery of the clamp body 12.

A rotational force is applied in the direction. The clamp body 12 normally presses the clamp part 13 against the end surface of one side of the arcuate rib 8C by the biasing force of the torsion coil spring 14, and due to this pressure contact, the magnet wire 15 wound around the armature core 2 (see FIG. ) can be clamped. Therefore, the clamp portion 1 of the clamp body 12
One end surface of the arcuate rib 8C that is pressed against the sleeve 3 serves as a clamp portion 16 on the sleeve 8 side 13u. Incidentally, a groove 17 is formed on the outer peripheral surface of the sleeve 8 and extends directly below from the clamp portion 16.

Such a jig 5 is removably attached to the mounting shaft portion 1b of the drive lIJ shaft 1, and the jig 5 is attached by attaching the cylindrical shaft 7 to the mounting shaft portion 1b.
This is done by fitting the pin 3 into the engagement groove 6 from above and turning it counterclockwise to allow the bottle 3 to penetrate to the end of the engagement groove 6. Then, in the process of fitting the cylindrical shaft 8 to the mounting shaft portion 1b from above, the holding member 10 comes into contact with the electric sash core 2 and the compression coil spring 11 is compressed, so that the electric sash core 2 is It is fixed onto the drive shaft 1 by a holding member 10.

Further, the jig 5 can be removed by slightly pushing down the cylinder shaft 7, rotating it clockwise, and then pulling it up to remove the bottle 3 from the engagement groove 6.

The installation and removal operations of the jig 5 are automatically performed by a chuck U (not shown) that grips the sleeve 8.
A groove 18 into which a 14M claw is inserted is formed. Also, chi 1 to this groove 18? In order to cause the clamp body 12 to be rotated in the direction opposite to the arrow by resisting the biasing force of the torsion coil spring 14 when the chuck jaw is inserted, a receiving piece 19 is provided on the outer periphery of the clamp body 12 to be pressed by the chuck jaw. is installed protrudingly. The jig 5 is configured as shown above.

Next, Fig. 4 shows the schematic overall configuration of the volume F11 device.
3, 20 is an air cylinder which is an external drive source for the clamp body 12, and is fixed to the base body (not shown) of all the coils. When the jig 5 is attached to the drive shaft 1, this air cylinder 2o drives the clamp body 12 to rotate in the direction opposite to the arrow, against the biasing force of the torsion coil spring 14. A projecting piece 21 is provided on the outer periphery of the clamp body 12 so as to come into contact with the rod 20a of the air cylinder 20. 22 is a nozzle which is the lead-out part of the magnet wire 15;
? It is inserted into the slot 2C of the IXII child core 2 and reciprocates back and forth within the range shown by the solid line and the two-dot chain line.

23 is a cutting mechanism for cutting the magnet wire 15 after the winding is completed, and includes a fixed blade 24 and a magnet wire 15.
As shown in FIG. 10, a movable blade 25 formed in a hook shape is used to draw 11).
A movable pressing member 26 is provided to hold the magnet wire 15 that has been kicked in between the movable blade 25 and the movable pressing member 26 is urged in a direction to press the movable blade 25 as shown by arrow B. It consists of a compression coil spring 27. 28
is a movable row arm that presses the middle part of the magnet wire 15 led out from the nozzle 22 and whose tip end is held between the movable blade 25 and the movable pressing member 26 in the horizontal direction toward the jig 5 side as shown by arrow C. be.

In addition, the nozzle 22. Three sets of cutting mechanisms 23 and movable rollers 28' are provided corresponding to the three pairs of clamp parts 13, 16, but only one set is shown in the drawing.

Next, the effect of the above 4M configuration will be explained. Now, as shown in FIG. 5, the tip of the magnet wire 15 is being held between the movable blade 25 and the movable pressing member 26, and the portion of the magnet wire 115 leading out from the nozzle 22 is pulled up diagonally. 1ffi for drive shaft 1.
It is assumed that the 1jff child core 2 and the jig 5 are not installed. From this state, first, the electric wafer core 2 is carried in and carried out (not shown) (according to the standard, it is fed downward from directly above the drive shaft 1 and placed on the upper end of the drive shaft 1, and then the jig 5 is similarly driven by a chuck mechanism (not shown). It is moved downward from directly above the !ll11 and is removably attached to the mounting part ib+, so that the electronic core 2 is driven by the holding member 10 of the jig 5 as shown in FIG. It is pressed and fixed to the shaft 1. When the setting process of the electric core 2 is completed, the rod 20a of the air cylinder 20 advances and presses the protrusion 21 of the clamp body 12, which causes the clamp body 12 to twist and tighten the coil. spring 14
The clamp portions 13 are rotated in the direction opposite to the arrow as shown in FIG.
Move away from 16. Next, the movable roller 28 moves in the direction of arrow C from the position shown by the two-dot chain line to the position shown by the solid line in FIG. . Then, the magnet wire 15 is slightly pulled out from the nozzle 22 and changes from the inclined state shown by the two-dot chain line in FIG.
and is pushed between both clamp parts 13 and 16. After this,
The Orad 20a of the air cylinder 20 moves back and the clamp body 1
2, the clamp body 12 rotates in the direction of the arrow due to the biasing force of the torsion coil spring 14, thereby clamping the magnet wire 15 between the clamp portions 13 and 16. After this clamping, the movable roller 28 returns and the movable blade 25 moves in the direction of the arrow to separate from the movable pressing member 26, releasing the clamping of the tip of the magnet wire 15. Now, when the distal end side of the magnet wire 15 is clamped by both clamp parts 13.16 of the jig 5 as described above, the drive @1 reciprocates in the circumferential direction while reciprocating up and down, and as a result, each nozzle Each tooth 2d of the armature core 2 corresponding to Nozzle 22 rotates B2 around the nozzle 22 as shown by the arrow in FIG. Teeth 2
dlc is being wound. At this time, magnet wire 1
The tip side of the movable blade 2 is clamped to a clamp part 13.16 of a jig 5 that moves integrally with the armature core 2.
Since the clamping between the magnet wire 15 and the movable pressing member 26 has already been released, there is no risk that the leading end of the magnet wire 15 will be cut off. Now, when the first winding stroke is completed as described above, the drive shaft 1 rotates in one direction by a predetermined angle in order to wind another tooth 2d. Similarly, winding is applied to another tooth 2d. When all the teeth 2d are wound in this way, the sleeve 8 of the jig 5 is clamped by the chuck condyle structure, and along with this clamping, the clamp body 12 is moved in the opposite direction of the arrow by the claws of the chuck condyle structure. The clamp part 1 is rotated by

Next, during loading and unloading, the groove operates to push the armature core 2 upward from the drive shaft 1, and as the armature core 2 is pumped out, the magnet wire A115 moves upward from the nozzle 22 as shown by two points g1fI in Fig. 9. being pulled out. And armature 1
The movable blade 2 temporarily stops above the drive 11, and in this state, the movable blade 25 moves in the direction of the arrow from the position shown by the broken line in FIG. 9, and as shown in FIG. Return movement Ivl in the opposite direction of the arrow. This movable blade 25
Due to the return movement of , the middle part of the magnet wire 15 is sandwiched between the movable blade 25 and the movable pressing member 26 , and in this sandwiched state, the movable blade 25 further moves in the direction opposite to the arrow mark, so that the fixed blade 24 and The magnet wire 15 is cut as shown by the solid line in FIG. After this,[
The first child core 2 is carried out, and everything returns to the state shown in Fig. 5, and winding is automatically applied to the armature cores that are carried in one after another in the same manner as described above. It is.
