[0007]

【Example】

 An embodiment of the present invention will be described below in detail with reference to FIGS. The pail pack 1 is a container having an inner cylinder 2 and an outer cylinder 3, which are arranged concentrically and open at the top. In the space between the inner cylinder 2 and the outer cylinder 3, welding wires 4 are stacked and stored in a loop shape. Reference numeral 5 indicates a loop-shaped wire laminated body of the welding wire 4. In the case of this embodiment, the wire laminated body 5 is the one in which the wire 4 is dropped and stored in a natural state, but it may be stored in a twisted state.

The lower end of the inner cylinder 2 is fixedly attached to the bottom plate portion of the outer cylinder 3, and the opening end of the outer cylinder 3 is closed by a conical lid member 14 to open the outer cylinder 3. The butting portion between the edge and the lower end of the lid member is fixed by a fastening band 15. A hole 16 through which the wire 4 passes is formed in the central top of the lid member 14, and a conduit tube 18 is connected to this hole 16 via a wire straightener 17. Then, the wire 4 is guided to the welding torch side through the conduit tube 18. The wire rectifier 17 is detachably attached if necessary.

A plurality of flexible band members, that is, a plurality of bands 6, are provided on the upper portion of the inner wall of the outer cylinder 3. In this embodiment, four bands 6 are provided at predetermined intervals. And are spaced apart in the circumferential direction, and their upper ends are attached to the upper portions of the inner wall of the outer cylinder 3, respectively. Further, a pressing member 7 is provided on the upper part of the wire laminated body 5, and the pressing member 7 is a rigid body having a wire drawing hole 8 in the center thereof and has a ring shape. This holding member 7 is provided with the same number of ring portions 9, that is, four ring portions 9 on the outer peripheral edge, and the ring portions 9 are spaced apart from each other in the circumferential direction and radially outward from the holding member 7. It has been extended. Further, the ring portion 9 is provided with an insertion hole 10 penetrating both sides thereof.

The band 6 whose upper end is fixed to the upper portion of the outer cylinder 3 is sandwiched between the inner wall of the outer cylinder 3 and the outer peripheral portion of the wire laminated body 5 through the insertion hole 10 of the pressing member 7. It is installed vertically. Referring to FIG. 3, the positional relationship between the ring portion 9 of the pressing member 7 and the band 6 is specifically shown. The upper end of the band 6 is fixed to the upper part of the inner wall of the outer cylinder 3 by double-sticking an adhesive tape 13. The upper end of the band 6 may be attached by an appropriate means such as directly fixing with an adhesive instead of the adhesive tape 13.

The lower end of the band 6 is provided so as to reach the bottom plate portion of the pail pack 1, and is held by the clamping force between the inner wall of the outer cylinder 3 and the wire laminated body 5. However, the lower end of the band 6 is held by the band 6. It is preferably fixed to the lower end of the inner wall of the outer cylinder 3. The shape and material of the band 6 are not particularly limited, but the band 6 has a flat cross section so as not to hinder the wire storage, for example, a cloth tape or a steel strip.

As shown in FIG. 2, in the outer peripheral portion of the wire laminated body 5, the pressing member 7 prevents the wire 6 from passing along the inner wall of the outer cylinder 3 together with the band 6 passing through the insertion hole 10, while In the peripheral portion, a ring-shaped gap 11 is formed between the outer wall of the inner cylinder 2 and the wire drawing hole 8. Therefore, the loop-shaped welding wire 4 stacked and stored in the outer casing 3 of the pail pack 1 is taken out above the pail pack 1 so as to rotate in the ring-shaped gap 11. become.

The upper part of the wire laminated body 7 is gradually lowered as the storage wire is consumed and decreased, and the holding member 7 placed on the upper part is also lowered while the band 6 is passed through the insertion hole 10. To do. This state continues until the pressing member 7 finishes descending, and the positional relationship shown in FIG. 3 is maintained until the end. Therefore, the welding wire 4, which is stacked and housed in a loop shape between the outer cylinders 3 of the pail pack 1, has a force that causes the twist to return to its original position, especially for a wire to which a twist has been applied in advance. It is inherent and always tends to spread outward. Further, even when the wire is dropped and stored naturally, when the wire is swung and pulled out, a similar force is applied to the wire, so that the wire always tends to spread in the outer peripheral direction. For this reason, when the wire is pulled out, the wire tends to jump up randomly along the inner wall of the outer cylinder 3. However, in this device, the band 6 and the pressing member 7 block the upper outer circumference of the wire laminated body 5. The wire is prevented from jumping up and popping out, and the smooth wire 4 can be taken out from the gap 11.

An experiment in which the pail pack 1 was vibrated was conducted by a vibration test device, and the presence or absence of interference between the band 6 and the insertion hole 10 was tested based on the relationship between the sizes of the band 6 and the insertion hole 10. In this test, the width of the band 6 is 12 mm, the thickness is 0.6 mm, and the width of the adhesive tape 13 that fixes the band 6 to the inner wall of the outer cylinder 3 is set to be sufficiently larger than the width of the band 6. The adhesive tape 13 was double stuck and fixed. The results of this test are shown in the table below. The vertical and horizontal directions in the table represent the ratio of the vertical width and the horizontal width of the insertion hole 10 to the band 8.

[0015]

[Table 1] According to the results of this test, the size of the insertion hole 10 is at least 1.5 times as wide as the width of the band 6 and at least vertically longer than the thickness of the band 6. It was confirmed that the band 6 and the insertion hole 10 did not interfere with each other and the adhesive tape 13 that fixed the band 8 to the inner wall of the outer cylinder 3 did not peel off when both were 3 times or more. Therefore, even if the pail pack 1 vibrates when the pail pack 1 is transported, if the relationship between the band 6 and the insertion hole 10 satisfies the above condition, the interference between the two is reduced and the pail pack of the band 6 is reduced. Since an excessive force is not applied to the upper fixed portion 1, the adhesive tape 13 fixing the band 6 is not peeled off, and the original function of the band 6 can be maintained.

The material of the ring-shaped pressing member 7 is not particularly limited, but is steel or synthetic resin such as vinyl chloride, for example. In the case of this embodiment, a weight 12 is provided on the upper surface of the pressing member 7 so as to be spaced apart in the circumferential direction. Therefore, the pressing member 7 itself may be made of a light material. Further, the insertion hole 10 of the pressing member 7 is provided in the ring portion 9 extending outward from the pressing member 7 in the radial direction, but the present invention is not limited to this, and the ring portion 9 may be eliminated to eliminate the pressing member 7. The insertion hole 10 may be provided near the outer peripheral portion.

Further, in this embodiment, a ring-shaped gap 11 is formed between the inner peripheral portion of the pressing member 7 and the outer wall of the inner cylinder 2, and the wire 4 is taken out from the gap 11. Alternatively, an elastic member may be provided on the inner peripheral portion of the pressing member 7, and the elastic member may be brought into contact with the outer wall of the inner cylinder 2. By doing so, it is possible to prevent the disorderly protrusion of the subsequent wire 4 when the wire 4 is taken out between the inner peripheral portion of the pressing member 7 and the outer wall of the inner cylinder 2.

[Effect of device]

 As described above, the welding wire take-out device of the present invention is particularly effective in taking out the welding wires taken up in the pile pack. In other words, the wire does not get entangled and entangled, so it is possible to take out the wire smoothly without interrupting the welding work, and it is extremely practical in spite of its simple structure. It is a highly effective device.

Further, the horizontal width of the insertion hole of the pressing member has a width of at least 1.5 times or more the width of the band member, and the vertical width thereof is at least 3 times or more of the thickness of the band member. By configuring it to have a width and limiting the size of the insertion hole for the band member, interference between the band member and the insertion hole is reduced even if the pail pack is affected by vibration during transportation. In addition, it is possible to prevent the adhesive tape for fixing the band member to the pail pack from peeling off and prevent the band member from coming off the inner wall of the pail pack.
