Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method in which a welding wire is entangled from a pile pack in which the welding wire is stacked and housed in a stacked state, and is smoothly and continuously taken out without tangling. And a member for taking out a welding wire.

(Prior art) As a large-capacity welding wire storage container, a pail pack is used, and the wire is taken out from the pail pack in order from the upper end of the wire loop laminate to the upper outside of the pail pack, This is done by guiding the wire to a welding torch through a conduit tube.

The welding wire stored in this pail pack is twisted within the range of elasticity limit, for example, 270 ° -3
It is stored with a twist of 60mm. For this reason, there is an internal force for twisting the wire in the pail pack, and when the wire is freed, it tends to bounce in the axial direction of the pail pack. For this reason, conventionally, a method has been proposed in which an annular holding member is mounted on the upper end of a wire loop laminate in a pail pack to hold the wire from above, thereby preventing the wire from jumping up. (For example, Japanese Utility Model No. 64-4764
issue).

On the other hand, the terminal end of the welding wire laminated in the pail pack is guided upward along the pail pack cylinder, taken out from the inside of the annular holding member, and the final end and the wire in the pail pack to be subsequently subjected to welding are taken out. A method has been proposed in which the starting ends are joined to communicate between the two pail packs, so that the welding wire is continuously taken out when the pail packs are replaced (for example, JP-A-59-220287).

[Problems to be solved by the invention]

However, when a single cylindrical pail pack without an inner cylinder is used, the wire is still entangled or entangled when the wire is taken out from the inner circumferential circle of the annular holding member, that is, the wire take-out hole. That is, since the single cylindrical pail pack has no inner cylinder, the hollow portion of the wire loop laminate is large, and therefore it is sufficient to take out one loop at a time from the top of the loop laminate, but two to three loops are taken out simultaneously. When,
In the hollow part, the wire jumps to release the twist,
This causes problems such as entanglement. If the wires in the pail pack are entangled during welding as described above, the wires are not fed to the welding torch and the welding operation cannot be continued.

Simultaneous removal of two or three loops into the hollow portion in the pail pack is particularly remarkable when a pail pack for continuous removal is used at the time of replacement of the pail pack. That is, as described above, since the end portion of the welding wire is arranged so as to extend from the inside of the ring to the upper side through the lower surface of the holding member as described above, the holding effect of the holding member is inevitably reduced. The subsequent two or three loops are easily pulled out to the hollow portion by being dragged by the loop taken out from the upper end of the body.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a member for taking out a welding wire which can be smoothly taken out without getting tangled when taking out the wire from the pail pack.

[Means for solving the problem]

The welding wire take-out member of the present invention is a wire take-out member from a pail pack containing a loop stack of welding wires, and an annular holding member placed on the upper end of the loop stack, and a pail pack It has a central wire passage hole attached to the upper end of the tube portion, and a take-out lid having a slit extending from the wire passage hole toward the wall of the tube portion.

[Action]

In the welding wire take-out member of the present invention, since the take-out lid having a wire passage hole at the center portion is attached to the upper end of the tubular portion of the pail pack, the succeeding 2-3 loops are dragged by the wire to be pulled up and collectively. Even in the case of being pulled out, the disordered movement of several loops of wires pulled out by the shielding action of the take-out lid is regulated, and normal wire can be taken out from the central wire passage hole.

In this manner, the holding member of the take-out member of the present invention prevents the wire at the top end of the loop body from jumping up while being lowered with the upper end of the loop body as the wire is consumed, and is pulled out from the upper end of the loop body by the take-out lid. Restrict the degree of freedom of the wire and smoothly take it out of the pail pack.

Also, since the takeout lid has a slit extending from the wire passage hole toward the cylinder wall of the pail pack, that is, in the outer peripheral direction,
The end for welding in the continuous take-out pail pack at the time of the pail pack exchange can be passed through the slit and arranged at the slit end, so that it does not hinder the normal wire take-out, and the terminal and the next welding It can be bonded to the wire start end of the pail pack to be provided. When the wire below the holding member in the pail pack is used up, the wire leaves the holding member at the bottom of the pail pack, rises while forming a U-shape, and finally undergoes plastic deformation from the slit of the takeout lid. The wire is taken out of the pail pack without any change, and the process moves to the wire take-out in the next pail pack.

〔Example〕

Hereinafter, the present invention will be described based on embodiments shown in the drawings.
Of course, the following examples do not limit the present invention, and various embodiments can be considered without departing from the spirit of the present invention.

FIG. 1 is a longitudinal sectional view showing a use state of a member for taking out a welding wire according to the present invention. Pail pack 1 is cylindrical part 2
And a bottom portion 3, in which a twisted welding wire is housed in a loop form in a stacked manner. Numeral 4 denotes a loop stack accommodated in the stack, and an annular holding member 5 is placed on the upper end of the loop stack 4.

The holding member 5 of the present embodiment includes a flat plate portion 5a that contacts the upper end of the loop laminate and holds it under its own weight, and a frustoconical conical portion 5b that protrudes in an eaves shape. A restraining member can be appropriately employed.

The protrusion of the wire from the gap between the outer periphery of the holding member 5 and the inner wall of the pail pack cylinder 2 is eliminated by the method of Japanese Utility Model Publication No. 64-4764, 11 is a string used in the method, and 12 is a string 11 inserted. Hole. Of course, the prevention of the protrusion from the gap is not limited to this method, and other appropriate known means can be adopted.

A take-out lid 6 is placed on the upper end of the cylindrical portion 2. The take-off lid 6 has a wire passage hole 7 at the center thereof, and a slit 8 extending from the passage hole 7 toward the wall of the cylindrical portion 2. Reference numeral 9 denotes a hinge for intermittently connecting the passage hole 7 and the slit 8, and reference numeral 10 denotes a protrusion provided on the lower surface of the take-out lid 6. The protrusion 10 is fitted to the upper end of the cylindrical portion 2 to fix the take-out lid.

When the welding wire take-out member, that is, the holding member 5 and the take-out lid 6 are attached to the pail pack 1 and the welding wire is taken out from the pail pack, the holding member 5 is held down as shown in FIG. The loop is sequentially pulled out from the wire at the upper end of the loop stack 4 one by one into the inner peripheral hole of the holding member. The drawn wire W rises while turning, is converged by the wire passage hole 7 of the take-out lid 6, is taken out of the pail pack, and is further connected to the conduit tube (not shown) through the wire inlet of a conduit tube (not shown) located above the pail pack. And fed to the welding location.

On the other hand, the terminal end portion E of the wire is arranged along the pail pack cylinder portion 2, passes through the lower surface of the holding member, is taken out from the inner peripheral hole, and is attached above the cylinder portion 2 with tape or the like. At a suitable time when the loop laminate has been reduced, the take-off lid 6 is opened and the end E of the wire is slit 8
And connected to the beginning of the wire of the next pail pack juxtaposed next to it. Of course, this connection operation may be performed by the time the pail pack is replaced, so that the connection time is not particularly limited. The hinge 9 is closed when the wire is normally taken out and opened when the pail pack is replaced. The hinge 9 is not particularly necessary if the wire W passes through the wire passage hole 7 without being caught by the slit portion 8 and passes through the slit without being caught by the end portion of the wire. It is easy to make the wire passage hole such a shape. The diameter of the wire passage hole 7 and the width of the slit 8 are not particularly limited in dimensions such as length, but the diameter of the wire passage hole 7 is preferably 16 to 80 times the wire diameter from the viewpoint of wire take-out. The width is preferably 12 to 40 times the wire diameter. In addition, the slit length (including the wire passage hole) is preferably such that the final wire ascending while exhibiting a U-shape can pass without being caught and without causing plastic deformation, and from this point it is 160 times or more the wire diameter. Good to do.

For example, when taking out a welding steel wire of 1.2 mmφ from a pail pack with a cylinder diameter of 500 mm, the diameter of the take-off lid is 530 mm.
mm, wire passage hole diameter: 30 mm, slit width: 15 mm, slit length: 250 mm.

In this example, the slit 8 is provided only on one side of the wire passage hole 7, but it may be provided on both sides, that is, in a diameter shape, or may be provided on a curved line if necessary.

In this example, the take-out lid was flat, but may be conical.
In addition, the type that covers the inside of the pail pack as described above also has a moisture-proof and dust-proof effect on the wires in the pail pack during the unloading operation or at rest, but it does not necessarily cover the inside of the pail pack. Good.

The materials of the holding member and the take-out lid are not particularly limited as long as they have the above functions. For example, it is made of synthetic resin such as polyvinyl chloride or ABS resin, steel or paper. In this embodiment, the take-out cover is a cover exclusively used for taking out the wire. However, a usual cover used for transporting and storing the pail pack may be provided with a wire passage hole and a slit and used together. FIG. 2 shows this embodiment. In FIG. 2, reference numeral 60 denotes a lid for transporting and storing the pail pack attached to the cylindrical portion 2 by the fastening belt 13, and a wire passage hole 70 extends in the center of the cover 60 in the outer peripheral direction from the passage hole. A slit 80 is provided. At the time of transportation and storage of the pail pack, a tape 14, such as vinyl, cloth or paper, is attached as shown in FIG.

〔The invention's effect〕

As described above, according to the present invention, the wire can be taken out extremely smoothly from the wire loop at the upper end of the loop stack of the welding wires housed in the pail pack without causing any inconvenience of entanglement or entanglement. In the present invention, the occurrence rate of entanglement and entanglement Was reduced to less than 1/10 compared to the past. The take-out member of the present invention exerts its effect on continuous take-out at the time of changing the pail pack of welding wires stacked and stored in a single cylindrical pail pack given a twist, and without interrupting the welding work, The take-out can be performed smoothly and continuously, and its practicality is extremely high despite its simple configuration.
