JPS58103912A - Method for drawing out iron wire rod coiled by carrier - Google Patents

Abstract

PURPOSE:To supply an iron wire rod without causing snarls and kinds and to improve operating efficiency, by drawing out the wire rod through a spring, placed freely rotatably at the upper part of a carrier. CONSTITUTION:The draw-out end part 3a of an iron wire rod 3 is drawn out through an internal space of a bearing 4, placed at the top of a carrier 2 freely rotatably on the surface parallel to the surface formed on the whole by the coiled wire rod 3, and through an internal space of a spring 5, of which one end is connected to the bearing 4 so as to be extended by a proper length to the outside from the carrier 2. The wire rod 3 prepared by coiling it in a bundle around the carrier 2, is revolved by the spring 5 around the center of wire-rod- coiling carrier 2 at the time of drawing out, and the wire rod 3 is smoothly unfastened and drawn out without causing snarls and kinds of the rod 3, and/or without wire rod breakages due to them because the rod 3 is drawn out while being vibrated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for drawing out a carrier-free iron wire for use in protecting an electric cable, etc., of iron wire armor, etc.

So-called iron wire armor, in which iron wire is wound horizontally, is often used as a protective layer for electric cables, etc. There are two ways to wind the iron wire horizontally: one is to wrap the iron wire around the cable, and the other is to rotate the cable and wrap the iron wire around it. In the former method, the iron wire is supplied by bobbin removal, and in the latter method, iron wire sheathing is carried out by bobbin removal or carrier removal. This iron wire feeding method has the advantage of being able to increase the length of iron wire fed at one time.

Although the method of removing the carrier is preferable, there is a risk that the iron wire may become tangled, kinked, or broken when the iron wire is drawn out.

Therefore, an object of the present invention is to provide a method for drawing out carrier-removed iron wire that can eliminate the above-mentioned drawbacks, supply iron wire without causing tangles, kinks, wire breaks, etc., and thereby dramatically improve work efficiency. It is about providing.

The gist of the present invention is to draw out the iron wire through a freely rotatable spring on the top of the carrier.
Embodiments according to the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining a method for drawing out iron wire according to an embodiment of the present invention. will be prepared. The lead-out end 6a of the iron wire O has a bearing 4 on the top of the carrier 20 that is rotatable in a plane parallel to the overall winding plane of the iron wire O, and a bearing on one end of the wire so as to extend outward from the carrier 2 for an appropriate length. 4 and is pulled out through an internal space (not shown) with a spring 5 connected to the spring 5 .

In this way, the iron wire 6 prepared by being wound around the carrier 2 is rotated around the winding center of the iron wire on the carrier by the spring 5 and vibrated when the iron wire is drawn out, so that the iron wire is not tangled or kinked. The iron wire in the bundled state can be smoothly untied and pulled out without causing wire breakage or the like. Here, the spring force, length, internal space, and other dimensions and features of the spring 5 should be appropriately selected depending on the dimensions and features of the iron wire to be used. The iron wire may be extremely bent and obstruct the smooth drawing of the wire, or
It should be selected so that it has extremely high rigidity and does not cause moderate vibration to the iron wire.

As described above, according to the present invention, the iron wire prepared in the carrier in a bundled state can be smoothly unraveled by passing through the spring that is rotatable around the winding center of the iron wire on the carrier and pulling it out. In addition, it is possible to prevent kinks, wire breaks, etc., thereby making the wire drawing work more efficient.
