Description

[Detailed description of the invention] [Field of industrial application] The present invention is a method for smoothly and continuously taking out welding wires without entanglement from a pail pack containing coiled welding wires in a stacked manner. The present invention relates to a welding wire extraction member.

[Conventional technology and problems]

A pail pack is used as a large-capacity welding wire storage container, and the wires are taken out from the pail pack in order from the top of the wire coil body to the outside of the pail pack, and bent with a wire straightener as necessary. After removing the wire, the wire is guided through the conduit tube to the welding torch by a wire feeding mechanism provided on the welding torch side. Various take-out devices have been devised to smoothly take out the welding wire from the pail pack, but all of them are difficult to take out continuously over a long period of time, especially when high-speed take-out is performed in response to high-efficiency welding. This is not satisfactory as tangles etc. occur.

In particular, when the welding wire is twisted within the elastic limit, such as the welding wire housed in recent pail packs, for example, the welding wire is housed with about 360 degrees of twist per turn of the wire. When the wire is released, it has a tendency to bounce in the axial direction of the pail pack.
Tangle etc. appear more clearly. For this reason, a conventional method has been adopted to prevent the wire from jumping up by placing an annular restraining member on the upper end of the wire coil body in the pale pack and pressing the wire from above (such as Utility Model Application No. 57-138856). , has been effective.

However, as monocylindrical pail packs without an inner tube have recently begun to be used, a problem has arisen in which the wires become tangled when the wires are taken out from the inner circumference of the annular holding member, that is, the wire take-out hole. . In other words, since the monocylindrical pail pack does not have an inner tube, the hollow part of the wire coil body is large, so when two or three coils are taken out from the top of the coil body at the same time, the wire tends to untwist in the hollow part. This causes inconveniences such as tangles and tangles.

[Means and actions to solve the problem]

The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art, and its purpose is to provide a welding wire take-out member that can be taken out smoothly without getting tangled or tangled when taking out the wire from a pail pack. , the gist of which is a member for taking out welding wire coiled and stacked in a pail pack, which is placed on the upper end of the welding wire coil body and descends with the upper end of the coil body to remove the coil body. an annular suppressing member that suppresses the
The welding wire take-out member is comprised of a truncated cone-shaped regulating member that is placed separately on the suppressing member and has a wire passing hole formed in its upper part that is narrower than the inner circumferential hole of the suppressing member.

The present invention will be explained below based on specific examples shown in the drawings. Of course, the following specific examples do not limit the present invention, and various embodiments can be considered as appropriate without departing from the gist of the present invention.

FIG. 1 is a cross-sectional view showing the state in which the welding wire take-out member of the present invention is used, and FIG. 2 is an overall perspective view of the take-out member of the present invention.

The pail pack 1 has a body part 2 and a bottom part 3, and twisted welding wires are stacked in a coil shape and housed inside the pail pack 1. 4 shows a coil body of this welding wire. A welding wire take-out member 5 is placed on the upper end of the wire coil body 4 housed in the pail pack 1. This take-out member 5 is an annular holding member 6 that directly contacts and presses the coil body 4.
and a regulating member 7 for regulating the movement of the wire W that is placed separately on the suppressing member 6 and being pulled up. This regulating member 7 has a wire passage hole 8 formed in its upper part which is narrower than the inner circumferential hole of the suppressing member 6, and has a truncated conical shape in which the lower part thereof is formed to have a larger diameter than the inner circumferential hole of the suppressing member 6. There is.

In addition, the outer periphery of the holding member 6 and the pail pack body 2
The wire protruding from the gap with the inner wall was developed in 1977.
-138856 method, 9 is a string used in this method, and 10 is a hole provided in the restraining member 6 through which the string 9 is inserted.

Since the welding wire take-out member 5 of the present invention is constructed as described above, it brings about the following functions and effects when used. Welding wire W
is pulled out one coil at a time from the upper end of the coil body 4,
It is pulled upward from the passage hole 8 of the regulating member 7. The wire W is turned upward while turning, but this turning movement of the wire W is regulated by the passage hole 8,
The wire W rises in a stable state without having a very large swing width (circular movement diameter). That is, the wire W is pulled up while contacting the edge of the passage hole 8, and the contact point performs a circular motion. Since the regulating member 7 is placed separately on the restraining member 6, the movement of the regulating member 7 due to the regulation of the wire W is not transmitted to the restraining member 6, and therefore the coil body restraining function of the restraining member 6 is not reduced. do not have.

Furthermore, even when two or three coils are pulled out together into the internal space of the coil body 4, the wire holding function of the restraining member 6 is not reduced, and the shielding action of the regulating member 7 and slight up-and-down rocking prevent the pulled out wire from being pulled out. It is possible to restrict the disordered movement and allow the wire to be taken out normally from the passage hole 8.

In this way, as the wire W is consumed, the take-out member 5 moves down together with the upper end of the coil body 4, and its restraining member 6 prevents the wire coil at the upper end of the coil body 4 from jumping up, and its restricting member 7 pulls it out from the coil body 4. The degree of freedom of the wire W is restricted and the wire is taken out upward one coil at a time in an orderly manner.

In addition, in the present invention, the narrow wire passing hole 8 of the regulating member 7 is formed above the position of the restraining member 6, so that excessive bending force is not applied to the wire and the wire can be taken out without strain.

The material of the restraining member and regulating member of the extraction member is not particularly limited, but may be made of steel, polyvinyl chloride,
Made of synthetic resin such as ABS resin.

[Effect of idea]

As explained in detail above, in the present invention, the wire take-out member placed on the upper end of the wire coil body stacked and housed in the pail pack is placed separately on the annular holding member and the holding member, and the wire is removed. Since it is composed of a truncated cone-shaped regulating member with a narrow passage hole formed in the upper part for taking out the wire, there is no possibility of tangles caused by disordered behavior of twisted wires.
This prevents inconveniences such as tangling and allows the wire to be taken out smoothly. The restraining member of the present invention is suitable not only for removing ordinary welding wire continuously for a long time or at high speed, but also for welding wire that has been twisted and stored in layers in a single cylindrical pail pack. It is effective in taking out the wire, and it is possible to smoothly and continuously take out the wire without interrupting the welding work, and despite its simple configuration, its practicality is extremely high.
