Abstract

PROBLEM TO BE SOLVED: To wind an electric wire so as not to damage a projecting part and so as not to leave a row interval so much when arranged winding is performed by winding the electric wire having a projection round a winding barrel part after being guided by this by inserting it into a plastic guide pipe, and preventing contact of mutual electric wires having projections. SOLUTION: A plastic guide pipe 4 is formed so that a wire can be optionally inserted even when a winding thickness is changed after a half-split or a notch is formed. Its tip is obliquely cut, and a cut end 4a is opposed to a winding barrel part 6a of a winding drum 6, and therefore, rolling-in at winding time to the winding barrel part 6a of an electric wire 1 having a projection can be prevented. In the plastic guide pipe 4, the cut end 4a side is contacted with the winding barrel part 6a, and is run along a previously wound electric wire part, and a separate interval can be set by a thickness quantity of the pipe itself to a now winding electric wire part, and therefore, they can be wound so that projecting parts of both electric wire parts do not contact with each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing a projection wire from being damaged when winding the projection wire used in a transmission line or the like.

[0002]

2. Description of the Related Art Conventionally, techniques for winding electric wires include:
In general winding of an electric wire, since the aligned winding is performed by a contour winding, the wire is wound so as to slide down from the previous electric wire at the time of winding. In addition to the above, the traverse pitch is made large so that the wires do not come into contact at all. In this case, the gap between the rows is increased and the gap is increased.
Due to the influence, the layer falls and the lower winding layer protrudes, so that the winding worker performs winding while adjusting.

[0003] On the other hand, in the case of an electric wire having projections, it is difficult to make a space between rows.
According to the above winding method, the electric wire is easily damaged, and the adjustment is difficult according to the above winding method. (Because the width between the rows differs depending on the position of the protruding portion for each layer.) Therefore, as a conventional method of winding a wire with a protruding wire, a person is always attached to the winding portion and the wire is wound. They were working so that they would not be damaged and that the gaps between rows were not too wide.

[0004]

To summarize the above-mentioned problems in the prior art, first, in the case of aligned winding in a contour winding state, in the case of a wire with projections, a delay in traverse or a projection in the state of a winding layer is caused. Comrades hit each other, thereby causing scratches on the projections. In the case of winding with a large traverse pitch, the winding is performed with an excessively large gap between the rows so as not to cause damage, and the layer falls off, loosening occurs, and the lower winding layer protrudes.

Therefore, the problems to be solved by the present invention (objects)
Makes it possible to wind the wires with projections so as not to follow the scratches on the projections and not to open the rows too much when the windings are lined up. It is an object of the present invention to provide an apparatus for preventing a trauma at the time of winding a wire with a projection, which can perform the above winding.

[0006]

According to the present invention, there is provided an apparatus for preventing damage when winding an electric wire, which uses a plastic guide pipe through which an electric wire with a projection can be passed. So that the projecting wire is guided through the plastic guide pipe and wound around the winding body, thereby preventing the projecting wires from coming into contact with each other. is there.

In a preferred embodiment, the plastic guide pipe is cut in half or notched to simplify the line-through. Further, the tip of the guide pipe is cut obliquely, and the cut end faces the take-up drum section, thereby preventing the guide pipe from being caught in the take-up. The plastic guide pipe is variable in angle so that it can cope with changes in the winding layer. Further, the plastic guide pipe can be detached at the end of the winding drum, or can be automatically or electrically detached from the winding drum.

[0008] The thickness of the plastic guide pipe is variously selected in accordance with the way of clearance and the size of the projection of the electric wire with projection. In addition, the winding machine having the winding body is a winding machine of a drum traverse type or a traverse type.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a preferred embodiment of a device for preventing a trauma when winding a wire with projections according to the present invention. In this embodiment, the low-noise overhead ground wire 1 or the hard-to-snow overhead ground wire 2 is used as the electric wire with a projection, and the low-noise overhead ground wire 1 is used as a winding state.

In the figure, reference numeral 5 denotes a main body of the trauma prevention device, which is attached to the guide roller 3. This trauma prevention device body 5
Is provided with a plastic guide pipe 4. This plastic guide pipe 4 is a low noise overhead ground wire 1
A member that does not damage the wire, such as a vinyl chloride pipe, a nylon pipe, an acrylic resin pipe, or the like, has an inner diameter that allows the wire 1 with a projection to pass therethrough, and cuts or cuts the wire even when the winding thickness changes. You can freely pass through. Further, the tip is cut obliquely, and the cutout 4a faces the winding drum 6a of the winding drum 6, thereby preventing the wire with projection 1 from being caught in the winding drum 6a. ing.

The plastic guide pipe 4 is
By making the cut 4a side contact the winding body 6a and along the previously wound wire portion, the gap width can be set by the thickness of the pipe itself with respect to the wire portion to be wound now. In this way, it is possible to wind up such that the projection of the wire portion to be wound now does not contact the projection of the already wound wire portion.

Further, the guide pipe 4 is linked to the trauma prevention device main body 5 by a wire or the like so as to be variable in angle so as to cope with a change in the wound layer. In addition, the guide pipe cannot be used at the end of the drum because the guide pipe cannot be used at the end of the take-up body 6a, that is, at the flange. These guide pipes may be variable as long as they are naturally variable by contacting the leading end winding body 6a of the pipe itself or are mechanically driven by electric power, air and a cylinder. Further, it is preferable that the guide pipe be detached from the winding drum section 6a automatically or electrically.

[0013] According to the trauma prevention device of the embodiment having the above-described structure, the projecting electric wire portion is prevented from directly hitting the already wound electric wire portion. Guide can be performed, and furthermore, winding can be performed at regular intervals. These have cleared the problem of the phenomenon of scratches between rows.

[0014]

According to the present invention as described above, it is possible to wind the electric wires with the projections so as not to follow the scratches on the projections and not to make the space between the rows excessively when the electric wires with the projections are aligned and wound. In addition, it is possible to achieve an intended problem (object) of providing a device for preventing a trauma at the time of winding a wire with projections, which can perform the above-mentioned winding without a person always attaching to the winding portion. . In addition, it is possible to prevent scratches between the rows when aligning and winding the wire with projections, thereby facilitating the aligning winding, and winding can be performed at a constant interval, thereby preventing layer drop.
