Description

[Detailed Description of the Invention] The present invention relates to a device that alternately and continuously winds bran material such as electric wire onto two winding frames, in which a predetermined amount of bran material is wound onto an empty winding frame. The present invention relates to a continuous wire winding machine that is equipped with a device for capturing the winding end portion of a wire rod wound on a winding frame side by a predetermined amount.

In a winding machine that is not equipped with a device for capturing the wire winding end of the wire frame after a predetermined amount of wire has been wound, the wire moves from the reel with the predetermined amount of wire wound to the empty reel at the same time. When stopping a reel that is being wound at a fixed rate, especially when the reel is wound at high speed, due to its mechanical and electrical characteristics,
It takes several seconds for the winding to completely stop.

During this time, the winding frame rotates several times, and the winding end of the cut wire gets loose and damages the outer wire layer already wound inside the winding frame, making it defective. In some cases, there is a danger that the end of the winding may be torn off and scattered, and in the case of particularly hard wires, the wire already wound inside the winding frame may loosen due to springback, causing the winding shaft to separate from the winding frame. It has drawbacks such as requiring a great deal of effort to remove it. In order to solve these shortcomings, the Special Publication No. 48-3131
A continuous line village capture machine disclosed in Publication No. 3 has been proposed (prior art).

This prior art is configured as shown in FIGS. 6 and 7,
It operates as shown in FIGS. 8 to 14.

That is, in FIGS. 6 and 7, in a device that alternately and continuously winds a wire 2 such as an electric wire onto two winding frames 1 and 1', a wire rod 2 such as an electric wire is wound on the winding shaft extension line of the winding frames 1 and 1'. Cylindrical covers 6, 6' that can be placed over the winding frames 1, 1' are provided so as to be movable in the direction of the roll, and axial slits a are provided in the peripheral walls of the covers 6, 6' to allow the wire to be drawn in. Covers 6, 6 that cover the ends of the wire rods wound around the winding frames 1, 1'
In Fig. 6, 3 and 3' are winding shafts, 4 and 4' are drive shafts,
5 and 5' are collars, 7 and 7' are cylinders, 8 is a wire guide, 9 is its cylinder, 10 and 10' are wire cutting devices, 1
Reference numerals 1 and 11' indicate catching claws. By the way, in the conventional technology using cylinder covers 6, 6' having slits a shown in FIG. 6, the end of the wire material whips until the winding frame (wheel) stops, which causes the already wound wire material to be whipped. It was found that the problem was that it caused damage.

The reason for this is as follows.

The wheel rotates considerably due to inertia until it stops, but first, as shown in Figure 8, when the linear object is cut, the end is regulated by the edge 12 and pulled into the cover 6 as shown by symbols b → c → d. It will be done.

However, when the terminal rotates once and comes to the slit a again as indicated by the symbol e→f in FIGS. 9 and 10, the end begins to swell as indicated by the symbol f due to centrifugal force.

Then, when the terminal leaves the edge 13 as shown in FIG. 11, the terminal will fly out of the edge due to centrifugal force as indicated by symbol g.

However, when it rotates further, it is restricted by the edge 12 and the terminal moves into the slit with the symbols h→i→i in FIGS. 12 to 14.
This movement causes it to hit the already rolled bran layer, often causing damage. In short, in the prior art, the cylinder cover 6 having the slit a
．． The inner circumferential wall of 6' catches the pulled end, but as long as the winding frames 1 and 1' are rotated, the end receives centrifugal force and flies outward from the edge 13 of slit a, returning to slit a. The wire is drawn in under the control of the edge 12 of the wire, and the end thereof deviates as shown in the direction f→g→h→i and hits the already wound wire layer, causing damage. The present invention provides a continuous wire winding machine in which the ends of the wire rod are captured by the above-mentioned tube cover, and by devising the tube cover,
This prevents the wire ends from protruding outside the cover due to centrifugal force, thereby eliminating the above-mentioned problem with the wire ends.
In the present invention, a wire such as an electric wire is wound alternately and continuously around two winding frames, and a cylindrical cover that can be placed over the winding frame is provided on the extension line of the winding axis of each of the winding frames. In the movable one, each of the cylindrical covers has a first

The first cylindrical cover and the second cylindrical cover are respectively provided to be movable in the axial direction, and have different cylinder diameters, and further,
When each of the first tubular cover and the second cylindrical cover is placed on each reel frame, the tube opening □ green of the first cylindrical cover and the tube closing green of the second cylindrical cover correspond in the direction of the piece. An annular space that overlaps in the axial direction and allows the wire to be drawn in is formed between the outer circumferential wall of the tube closing green and the inner circumferential wall of the tube closing green, and the end of the edge material wound around the winding frame is connected to the winding frame. The first cylindrical cover and the second cylindrical cover are configured to be captured via inner circumferential walls that are continuous in the circumferential direction.
