Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a restraining member for welding wires which are stacked and housed in a loop in a pail pack. This invention relates to a welding wire holding member suitable for continuously taking out wire from a pail pack.

[Conventional technology and problems]

Generally, when welding wire in a pail pack is used, it is when a large amount of welding is to be performed, and the amount of welding wire used is large, and it is important to increase welding efficiency, and for that purpose, the wire in the pail pack is used up. It is advisable to start feeding wire from a new pail pack immediately. For this purpose, there is a technique disclosed in Japanese Utility Model Application Laid-open No. 1583/1983 as a technique for taking out the wire from inside the pail pack. In this technology, a slit is formed in the annular holding member from the inner circumference to the outer circumference, and by passing the terminal end of the wire arranged along the outer circumference of the wire stack through this slit, when replacing the pail pack, This technology makes it possible to separate the wire from the holding member. Although this conventional technology allows the pail pack to be replaced continuously, since the slit opening of the holding member is formed in an acute angle, when the wire is detached from the holding member, it is likely to get caught, increasing the resistance to take out the wire. There were flaws.

[Means and actions to solve the problem]

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional technology, and is a welding device in which wires are stacked and housed in a loop in a pail pack, and the wire ends are arranged upward along the body of the pail pack. An annular holding member placed on the upper end of the wire,
A notch extending from the inner circumferential side of the holding member to the wire terminal position is provided, and the notch has a V on the inner circumferential side.
It is characterized by having a Y-shape or an X-shape with a wire-shaped opening and a wire terminal holding portion on the outer circumferential side.

The present invention will be described below based on specific examples shown in the drawings, but the following specific examples are not intended to limit the present invention, and various specific examples can be considered as appropriate without departing from the gist of the present invention.

FIG. 1 is an overall perspective view (partially cut away) showing how the welding wire holding member according to the present invention is used. As shown in the figure, welding wires are wound in a loop shape and housed in a stacked manner in the internal space of the pail pack 1. Reference numeral 2 indicates a loop-shaped stacked body (hereinafter referred to as a loop body) of this welding wire, and an annular restraining member 3 of the present invention is placed on the upper end of the loop body 2.

The welding wire is twisted, for example, approximately 300° per turn within the elastic limit of the wire, in order to prevent the weld bead from meandering during welding, and is housed in the pail pack as a loop. As shown in the figure, the wire loop 2 has its outer periphery in contact with the body wall of the pail pack, and its inner periphery forms an internal space.

As shown in the figure, the restraining member 3 has a notch 4 formed from its inner circumferential side toward its outer circumferential side. A wire take-out terminal end We is arranged on the outermost side of this notch 4, and the open end on the inner side is arranged so that the wire W that is pulled up during normal wire take-out does not get caught in the notch 4. In addition, it is formed in a V-shape that opens toward the inner circumference so that the wire W can smoothly leave the notch when the wire loop located at the lower end of the loop body 2 is taken out. In the illustrated example, the notch 4 provided in the restraining member 3 is a cutout hole that does not communicate with the outer circumferential side, and a V-shaped portion 41 is provided on the inner circumferential side and a Y-shaped portion is provided with a holding portion 42 for the terminal end We of the wire. It has a letter-shaped notch. Furthermore, the wire W being pulled up
Assuming that the notch end of the holding member that comes into contact first (hereinafter referred to as the front notch end) is 4a, and the notch end that comes in contact with the rear member later (hereinafter referred to as the rear notch end) is 4b, the rear notch end is equal to or greater than the front notch end. It is cut into a V-shape. This is to prevent the wire that is normally pulled up from getting caught in the notch 4 as described above.

The welding wire take-out terminal end We is made to stand up from the lower end of the loop body 2 as shown in the figure.
It is guided upward along the outer periphery of the pail pack 1, that is, along the body wall of the pail pack 1, and then passed through the outer circumference side end, which is the closed end of the cutout hole 4 of the restraining member 3, and further led upward, and its final end is closely connected. It is connected to the wire starting end of the pail pack from which the wire is taken out next.

Figures 2a, b and c are diagrams showing over time how the wire separates from the restraining member at the bottom of the pail pack. The wire W continues to be pulled upward (arrow B) and to the right (arrow A) from the upper end of the loop body until it reaches the lower end of the loop body.
When the states a and b are reached, the wire that follows the wire W is no longer located at the bottom of the holding member 3, and the notch hole 4
Since the wire continues from the closed end to the wire end We extending upward, the wire W gradually starts to pull out the wire end We from the cutout hole 4 as the wire W rises. In this way, as shown in c, the wire W disengages from the notch hole 4 and leaves the restraining member 3. Then, the process moves on to take out the wire end We and the wire in the next pail pack connected to the end We. In this way, in the present invention, the opening side of the notch provided in the holding member is V-shaped to make it easier for the wire to come out of the notch, so the behavior of the wire W at the bottom of the loop body described above is smooth, and the notch can be easily removed. There will be no snags caused by corners.

FIG. 3 shows another specific example of the present invention. This example differs from the case shown in FIG. 1 in that the notch 5 of the restraining member 31 is a notch hole in which the inner circumferential side and the outer circumferential side communicate with each other. In this case, when pulling up the wire at the bottom of the pail pack, the wire terminal end We must be located at the opening position on the outer peripheral side of the notch hole 5, and for this reason, the string members 6, 6' whose ends are fixed to the body wall of the pail pack , 6'' are inserted into the holes provided in the restraining member 31 to prevent rotation of the restraining member, and by arranging the wire terminal end We along the string member 6, the rising part is placed on the outer peripheral side of the notch hole 5. The shape of the notch hole 5 is adjusted to the opening position.
1. Both of the outer peripheral side openings 52 are V-shaped and X-shaped cut holes. The reason why the outer peripheral side opening 52 is V-shaped is to make it easier for the wire terminal end We to pass through the notch hole 5 when the wire is separated from the restraining member. In this example as well, the wire W is smoothly held at the bottom of the pail pack by the holding member 3
You can leave 1.

[Effect of idea]

According to the welding wire restraining member of the present invention, the notch provided in the restraining member has a V-shape open to the opening side, so that it is not pulled when the wire is separated from the restraining member as in the conventional case. The wire smoothly passes through the notch in the restraining member, releases the engagement with the restraining member, and proceeds to take out the wire from the next pail pack without causing any trouble such as getting stuck.
