Abstract

PURPOSE:To eliminate defect of easy entanglement, facilitate continuous taking- out with the space suppressed, and simplify refilling of bundle of electric wire on the way of taking out by forming a wire supply from wire holding tools capable of being stacked with an outer flange provided at the bottom of a cylindrical body and a removable outer flange at the top. CONSTITUTION:A bundle of electric wire A accommodatable within outer flanges 12 is mounted in each holding tool 10, and they are stacked one over another, and an outer flange 20 is installed on the uppermost holding tool 10. Therein the winding end at the inside of each upper laid bundle A is connected with the winding end at the outside of its lower laid bundle A. If in this condition electric wire is drawn out upward from the winding end at the outside of the uppermost bundle A, the wire contacts the periphery of the upper outer flange 20 or 12 and is paid out while sweeping aside, wherein there is no fear of collapse of bundles due to the drawn-out electric wire. When bundle A is to be refilled on the way of wire takeout work, the wire supply concerned is lifted and placed on a new holding tool 10 loaded with a bundle A.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention is applicable to
This invention relates to an electric wire supply used when stocking bundles of electric wires wound with wire rods or supplying the wire rods to cutting machines in the pressing process.

[Conventional technology]

As for the method of taking out the wire from the wound bundle of wires,
The second inner wire pulls out from the inner winding end of the wire bundle,
There is a removable type that is pulled out from the outer winding end.

In this pull-out type, when the wire is pulled upward, the tension causes the wire to dig into the inside of the wire bundle, causing tangles. An example is shown in FIG.

As shown in the figure, this electric wire supply has a support shaft set up in the center of a base a, and a plurality of piano wires C extending outward from the upper end of the support shaft toward the base a. It is installed with its lower end open.

In this electric wire supply, when the electric wire bundle A wound with the wire is inserted into the outside of the piano wire C, the electric wire bundle A is always pushed from the inside to the outside by the outward expansion force of the piano wire C. becomes. Therefore, even if the inner winding end of the wire bundle A is pulled upward, the wire bundle does not collapse, and the wire can be pulled out smoothly without becoming tangled.

In addition, as shown in Fig. 7, there is also a box in which the wire bundle is placed in a box having an opening e on the top wall d, and the wires are pulled out from the opening e. There are also those disclosed in No. 52-50373 and Japanese Utility Model Publication No. 5323550.

[Problem to be solved by the invention]

By the way, when taking out wires continuously from two bundles of wires using the above-mentioned internal wire supply, as shown in FIG. The supplies are lined up, and the outer winding end of the first wire bundle A1 and the inner winding end of the next wire bundle A2 are connected and pulled out.

Normally, the drawing position and direction of the wire are constant, so when the first wire bundle A1 is taken out, the next wire bundle A2
It was necessary to reinstall the wire supply into the first wire bundle A, or replace the entire wire supply.

Therefore, when using a large number of wire bundles, it is particularly time-consuming and requires a space for installing the wire supply.

Therefore, the object of this invention is to solve the drawback of the detachable type that tends to get tangled, and to facilitate continuous extraction from multiple bundles of wires.
Moreover, it is an object of the present invention to provide a TL electric wire supply and a method for taking out electric wires that can be carried out in a space-saving manner and furthermore, can easily replenish a bundle of electric wires during removal.

[Means to solve the problem]

In order to solve the above problems, the electric wire sub-wall of the present invention includes a stackable electric wire holder having an outer flange at the lower end of a cylindrical body that is penetrated by a bundle of wires wound with electric wires, and The structure consisted of an outer flange that was removably attached to the upper end of the fuselage.

In addition, when extracting wire rods from multiple wire bundles continuously,
In this invention, an electric wire bundle in which electric wires are wound so as to fit inside the outer flange of the electric wire supply is attached to the electric wire holder, and the required number of electric wire holders are stacked with their sleeves aligned, and the uppermost one is stacked. An outer flange is attached to the upper end of the cylindrical body of the wire holder, and the inner winding end of the upper wire bundle and the outer winding end of the lower wire bundle are respectively connected, and the wires of the wire bundle are connected to the upper wire bundle. We adopted a method of pulling it out while making contact with the periphery of the outer flange.

Furthermore, instead of the electric wire supply, an electric wire supply having outer flanges at both ends of the cylindrical body is used, and the electric wire is wound around the cylindrical body so as not to protrude from the outer flanges. It is also possible to pull out the electric wire.

[Function] In the wire supply configured as described above, if the wire bundle that fits inside the outer flange is attached, the wires pulled out upward will come into contact with the periphery of the outer flange located at the top of the wire bundle. Since the wires are sent out while escaping in the horizontal direction rather than directly upward, the wire bundle is prevented from breaking due to the wires being bowed out.

In addition, since a detachable method is adopted, it is possible to remove the wire holders while they are stacked upwards, and if the upper and lower wire bundles are connected, they can be removed continuously.

(Example) Examples will be described below with reference to the drawings.

The wire supply shown in FIG. 1 includes three wire holders 10 shown in FIG. 2(b) and an outer flange 20 shown in FIG. 2(a).
The wire holder 10 has an outer flange 12 at the lower end of a cylindrical body 11 that passes through a bundle of wires wound around the wire. A fitting part 13 is formed at the lower end of the cylindrical body 11, and the upper end of the cylindrical body 11 can be fitted to the lower end of another cylindrical body 11 to allow the cylindrical bodies 11 to be stacked one above the other.

A ring-shaped projection 21 is provided on the inner peripheral edge of the outer flange 20.
is provided, and this protrusion 21 is connected to the cylindrical body 11.
It can be removably attached by inserting it into the inner circumference of the

A method for continuously taking out wires from a plurality of wire bundles wound with wires using the wire supply configured as described above will be described below.

First, as shown in FIG. 3, the wire bundle A that fits inside each outer flange 12 is attached to each wire holder 10 and stacked vertically, and the outer flange 20 is attached to the uppermost wire holder 10. At this time, as shown in FIG. 4, the inner winding end of the upper wire bundle A and the outer winding end of the lower wire bundle A are connected. In this state, when the wire is pulled upward from the outer winding end of the uppermost wire bundle A,
The drawn out electric wire comes into contact with the periphery of the upper outer flange 20 or 12 and is sent out while escaping in the lateral direction rather than directly upward, so that the electric wire bundle is not broken by the drawn out electric wire.

If it is desired to replenish the wire bundle A while the wires are being taken out, the wire supply is lifted and placed on the new wire holder 10 with the Tl wire bundle A attached, as shown in FIG.

At this time, first connect the inner winding end of the lowest wire bundle A of which wire supply to the outer winding end of the newly added wire bundle A. In this way, it becomes possible to replenish the wire bundle A without stopping the removal of wires.

Note that any number of wire holders 10 may be stacked and used as required.

[Effects] As described above, in the electric wire supply of the present invention, the wires are fed out by the upper outer flange while escaping laterally instead of directly upward, so that the wire bundle is not bent as the wires are pulled out. This eliminates the drawbacks of the removable type.

In addition, since the wire holders can be stacked vertically, there is no need for additional installation space for a new wire supply, as is the case with conventional internal wire supply systems, and the wires can be taken out continuously by simply connecting the upper and lower wire bundles. It doesn't take much time.

Furthermore, it is very convenient to replenish the wire bundle by simply lifting the 'W wire supply and placing it on a new wire holder.
