Description

[Detailed description of the invention] (Field of industrial application) This 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.

(Prior art and problems) Pail packs are used as large-capacity welding wire storage containers, but 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 as needed. Correspondingly, after removing the curl with a wire straightener, the wire is guided through a conduit tube to a welding torch by a wire feeding mechanism provided on the welding torch side. Various take-out devices have been devised to make it easier to take out welding wire from the pail pack. , tangles, etc. occur, which is not satisfactory.

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, in the past, a method was 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 pail pack and pressing the wire from above (Utility Model Application No. 57-138856). etc.), it 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 single-cylindrical pail pack does not have an inner cylinder, the hollow part of the wire coil body is large. Therefore, if two or three coils are taken out from the top of the coil body at the same time, the wire will not be twisted in the hollow part. When trying to release it, it bounces, causing inconveniences such as tangles and tangles.

(Means and effects for solving the problems) The present invention has been made in order to eliminate the drawbacks of the above-mentioned prior art, and it is a welding method that allows wires to be taken out smoothly without getting tangled or tangled when taking out the wires from the pale pack. The purpose of the present invention is to provide a welding wire takeout member for welding wire, which is a welding wire takeout member that is twisted and stacked in a coil body in a single cylindrical pail pack. an annular restraining member placed on the upper end surface of the coil body of the wire and having an inner circumferential hole edge formed with continuous sawtooth irregularities so that the convex portion protrudes inside the periphery of the coil body; a truncated cone-shaped regulating member having a wire passing hole formed in the upper part that is narrower than the inner circumferential hole of the suppressing member, and the wire passing hole of the regulating member and the inner circumferential hole of the suppressing member are coaxial. In this way, the welding wire is taken out from a welding wire which is placed integrally or separately on the restraining 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. 1a is a cross-sectional view showing the state in which the welding wire take-out member of the present invention is used, and FIG. 1b 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 placed on the suppressing member 6 and being pulled up. The suppressing member 6 has a serrated continuous uneven shape (8 indicates a convex portion and 9 indicates a concave portion) on the inner circumferential hole edge, and is attached to the upper end surface of the coil body 4 so that the convex portion 8 protrudes inside the coil body circumferential end 10. It will be placed. In this specific example, the inner circumferential hole edge of the holding member 6 is serrated so that the inner circumferential end 10 of the coil body 4 is located approximately midway between the convex portion 8 and the concave portion 9, and approximately 50% of the total length of the inner circumferential end 10 is exposed. In other words, the holding member 6 is placed on the upper end surface of the coil body 4 so that approximately half of the circle formed by the inner peripheral end 10 is hidden by the convex portion 8 and approximately half is exposed (visible from above) by the concave portion 9. ing. The regulating member 7 has a wire passage hole 11 that is narrower than the inner peripheral hole of the restraining member 6.
is formed in the upper part, so that the wire passing hole 11 and the inner circumferential hole of the holding member 6 are coaxial,
The holding member 6 is fixedly attached or placed separately on the upper surface of the holding member 6. In this specific example, the regulating member 7 has a truncated conical shape, and its lower end is fixed to the convex end of the inner circumference of the restraining member 6. The reason why the lower part of the regulating member 7 is formed into a continuous uneven shape in alignment with the inner circumferential hole edge of the suppressing member 6 is to avoid inhibiting the action of the inner circumferential hole edge of the suppressing member 6 on the wire.

In addition, the outer periphery of the holding member 6 and the pail pack body 2
A method in which the above-mentioned gap is blocked by inserting the wire 12 that comes out from the gap between the inner wall and the hole 13 into the hole 13 provided in the restraining member 6 and hanging it between the inner wall of the pail pack body 2 and the coil body 2 (in actual practice) 138856)
This problem has been resolved. Of course, any known method can be used as appropriate, and there are no limitations on the treatment of this part.

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 held down by the restraining member 6 and pulled out from the upper end of the coil body 4 one coil (one turn) at a time to the center, and then pulled upward through the wire passage hole 11 of the regulating member 7. The wire pulled out at the continuous uneven portion of the inner circumferential hole edge of the holding member 6 exhibits rhythmic movement (the trajectory of the wire in this part becomes wavy), and as a result, the wire that is pulled out moves in a rhythmic manner. Since the wire coil after the coil is unwound and remains at the upper end of the coil body, there is no problem such as being drawn out several turns into the internal space of the coil body and getting tangled. Coil body 4
The wire W pulled out from the upper end rises while turning, but this turning movement of the wire W is prevented by the regulating member 7.
In other words, the wire W is pulled up while contacting the passage hole 11 and the side wall of the regulating member 7, so the swing width (swivel radius) is not too large and the wire W rises in a steady state. . Furthermore, even when two or three coils are pulled out together into the internal space of the coil body 4, the shielding action of the regulating member 7 restricts the disordered movement of the pulled out wire, making it possible to take out the wire normally from the passage hole 11. It can be done. When the wire W is pulled out from the coil body 4, particularly when it is pulled out from the upper surface of the coil body, the wire comes into contact with the edge of the serrated part of the inner circumferential hole edge of the restraining member 6, and is guided by the edge. The wire is then sent to the central axis of the coil body, and is smoothly taken out through the wire passage hole 11 of the regulating member 7. In this example, as shown in FIG. 1b, the sawtooth shape of the inner peripheral hole edge of the holding member 6 is not symmetrical on the left and right;
The side that guides the wire (the right edge of the serrated portion directly above the hole 13) is gentle, and the opposite side is steeply sloped. The shape shown is preferable when the right edge of the coil body 4 from the winding direction is used for guiding, because the gentler the slope, the easier the guide will be and the less caught.

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 regulating member 7 lowers the coil body 4.
The degree of freedom of the wire W drawn out from the wire is restricted and the wire is taken out upward one coil at a time in an orderly manner.

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.

A second specific example of the present invention is shown in FIGS. 2a and 2b.

FIG. 2a is a sectional view showing the second specific example in use, and FIG. 2b is an overall perspective view (partially cut away) of this extraction member. This specific example differs from the specific examples shown in FIGS. 1a and 1b in that the lower end of the regulating member 17 has a larger diameter and is placed separately on the outer circumference of the restraining member 16. In the regulating member 17 of this specific example, the first
It is not necessary to form a continuous uneven shape in synchronization with the continuous unevenness of the inner peripheral hole edge of the restraining member 16 as in the specific example of the regulating member shown in the figure. However, a hollow window may be provided in the side wall of the regulating member for the purpose of adjusting the weight of the entire extraction member 15, observing the state of the coil body, etc.
In the figure, 21 is a wire passage hole, and the other parts are the same as in FIG. 1. This specific example can also be expected to have the same wire extraction effect as the specific example shown in FIG.

In both the specific examples shown in FIGS. 1 and 2, the regulating member has a plate-like truncated conical shape, but it is also possible to make the wire passage hole a ring and attach the ring to the restraining member via an arm.

(Effects of the Invention) 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 on the annular holding member and the holding member, Since the restricting member has a narrow passage hole formed in the upper part for taking out the wire, problems such as tangles and tangles due to disordered behavior of the twisted wire can be prevented and the wire can 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.
