Abstract

PURPOSE:To reduce a damage of a wire material at the time of mounting and to improve its productivity by winding on a cylindrical jig out of a cylindrical core, inserting the jig along a coil guide inserted into the core, and mounting the winding on the core. CONSTITUTION:A coil stopper 41 and a coil guide 31 are inserted by aligning a cylindrical core 8 at the position of a groove for 1 winding. Then, a coil jig 11 in which a coil 9 is wound in the exterior is inserted along the guide 31. The end wire drawing unit 91 of the coil 9 is positioned at the groove for the winding of the core 8, and fixed at this time. Accordingly, when the jig 11 is moved down along the stopper 41, a force of the direction extending into the groove of the core 8 is generated, and the coil 9 on the jig 11 is mounted in the groove. As the jig 11 is moved down, a wire material for one revolution is mounted. when the drawing unit 91 of the end side of the coil 9 is moved to the groove, it is positioned to complete its mounting. Thus, it can prevent the wire material from damaging at the time of mounting to improve its productivity.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a cylindrical a-taly transformer for a VTR cylinder, in which a winding groove provided on the inner periphery of the cylindrical core,
This invention relates to an inner circumferentially wound green spiral incorporating device for incorporating a coil.

[Conventional technology]

Conventionally, as a technique for assembling a coil into a winding groove provided on the inner circumference of a cylindrical core, as shown in Japanese Patent Laid-Open No. 149015/1982, a wire rod is attached to the outer circumference of a jig inside the cylindrical core. There is a technique to attach it by wrapping it and unwinding it.

[Problem that the invention seeks to solve]

In the conventional technology, in order to wind the wire inside the small-diameter cylindrical core, it is necessary to wind the wire one turn at a time in the winding groove of the - layer, and the number of turns of the coil and the coil layer are As the number increases, there is a problem that the winding time becomes longer, and the process of processing the terminal wire of the coil cannot be done until the winding within the cylindrical core is completed, so it is difficult to parallelize the work. was there.

An object of the present invention is to solve the problems of the prior art described above, and to provide an internally wound green spiral assembly device that causes less damage to the melted material and has high productivity.

[Means for solving problems]

The object is to provide a means for spirally winding a wire around the outer periphery of a cylindrical jig outside a cylindrical core to which a coil is attached;
This is achieved by providing means for inserting a coil guide inside the cylindrical core and means for inserting a cylindrical jig along the coil guide.

[Effect]

In the present invention, by winding the wire outside the cylindrical core,
Since outer circumference winding is possible, winding and shaping become easier.

Furthermore, since the wire is wound helically around the outer periphery of the cylindrical jig, it is possible to wind the wire in a state close to the final installed diameter, which reduces damage to the wire. Moreover, by inserting the coil guide inside the cylindrical core, it is possible to prevent the coil covering from being destroyed when the coil is caught in the groove corners of the cylindrical core when the coil is installed. Further, the winding jig and the mounting jig can be used together.

These effects cause less damage to the wire and enable highly productive winding assembly.

Fig. 1 shows a state in which the cylindrical core is positioned, the coil stopper 41 is aligned with the lowermost winding groove 81K, and the coil guide 31 and the coil 2 wound on the coil jig U are prepared. .

The cylindrical cores are placed in the center of the core fixing unit l, the core chuck cylinder 22 is pivoted, and the core chuck 21 is
The nine cylindrical cores 1 are positioned at predetermined locations. At this time, as can be seen from FIG. Insert 15 into the core J. At this time, the insertion depth is adjusted to the position of the winding groove 810 where the coil E is attached, and the coil stopper sleeve 43 is driven to position the coil stopper 41. The winding groove When changing the coil stopper motor 43, the command value to the coil stopper motor 43 is changed.Then, as shown in FIG. 2(A), the coil is inserted into the tight cylindrical core.The insertion depth is Similarly to the coil stopper 41, the coil guide motor 55 is driven to precisely position the coil in accordance with the position of the winding groove 81.The thin plate 312 of the coil guide υ positioned at the predetermined winding groove 11181 is The coil guide 3 covers the winding groove 81 on the insertion direction side except for the winding groove 81, and the slit 313 of the coil guide υ is aligned with the predetermined pull-out groove 82 of the cylindrical core.

In this helical mm, the diameter of the cylinder is set so that it can be fitted and inserted into the inner diameter of the coil guide υ'', and the helical length of one rotation is set in the winding groove 81 of the cylindrical core;
Make the length of the coil the same as when the 0 is installed. Furthermore, since the depth of the spiral groove 111 is the same as the wire diameter of the coil E, the terminal wire pull-out portion 91 of the coil E is formed so as to pass over the spiral groove 111 and protrude from the outer diameter of the one coil jig. Ru.

The coil jig So, in which the coil E is wound and formed, is attached to the jig base 12 and fixed by the jig holding cylinder 14. At this time, as can be seen from FIG. 2(C), the terminal wire pull-out portion 91 of the coil
13.

Next, as shown in FIG. 2 (dl), insert the coil jig υ along the coil guide υ. the guide shaft 16.
, the linear bearing 17 is used as a guide to operate smoothly. In addition, since the outer diameter of the coil jig U and the inner diameter of the coil guide V are in the same state, the coil 2 on the coil jig does not come loose, and the terminal wire of the coil 2 protruding from the coil jig U The pull-out portion 91 is limited by the coil guide υ 315, and no positional deviation occurs in the rotational direction.

Furthermore, insert the coil jig. At this time, as shown in FIG.
It collides with the coil stopper 41 which has the same shape as the thin plate 512 and has no slit, and is positioned in the winding groove 81K of the cylindrical core. The coil jig is lowered along the inner diameter of the coil stopper 41. At this time, the coil jig is prevented from moving downward by the coil stopper 41 of the terminal wire pull-out portion 91, and the slit 3 of the coil guide 51
Since the behavior in the rotational direction is also restricted by 13, this action, which generates a force in the direction of spreading into the winding 1#81 of the cylindrical core A, works continuously, causing the nest 2■ (-1 I'll show you 5
K.

Step 2: Install the winding portion 90 of the coil 〇 on the coil jig υ into the winding groove 81.

Furthermore, the coil jig 1 is lowered (. Even after the edge material for one rotation has entered the winding groove 81 of the cylindrical core 1, the installation of the coil 2 continues. The winding groove 81 is not deep enough for the coil 2 to fit two ICs in the depth direction, and since the spiral coil 2 is compressed in the axial direction, the wire rods in the first and left turns are separated from each other. As a result, the two wires are aligned and installed in the axial direction within the winding groove 81.These effects work even if the winding is one turn, two turns or more, so it depends on the number of turns. Not done.

When the terminal wire pull-out portion 91 on the terminal end side of the coil E reaches the currently installed winding groove 81, it collides with the coil stopper 41 in the same manner as at the time of starting the installation, and is positioned in the winding groove 81. At this time, as shown in Figure 2 V)K,
The terminal wire pull-out portion 91 of the coil E enters the pull-out groove 82 between the cylindrical cores, and the installation of the coil E is completed.

When attaching the coil to a different location, change the feeding amount of the coil guide motor 35 of the coil guide unit 3 and the coil stopper motor 43 of the coil stopper unit A so that the coil is attached to the pull-out groove 82 of the cylindrical core A. Then, grip the core chuck 21 again and align it with the predetermined pull-out groove 82. These K make it possible to incorporate the coil 2 into the entire winding groove 81 of the cylindrical core.
