Description

[Detailed description of the invention] The present invention involves supplying the wire from above the pail pack to the wire storage section between the outer cylinder and the inner cylinder of the pail pack, and twisting the wire when discharging the wound and stored wire above the pail pack. This invention relates to a wire payout device for winding a pail pack, which twists the wire in advance so as not to cause a twist.

The wire that is supplied from above the pail pack and wound into the wire storage section between the outer and inner cylinders of the pail pack is twisted in the opposite direction to the twist when it is unwound to avoid twisting when the wire is unwound. Since the wires are given in advance, the wires frequently jump upwards in a disorderly manner and become tangled during dispensing.

This idea was created in view of the above-mentioned circumstances.
The object thereof is to provide a pail pack winding wire dispensing device which can effectively prevent the above-described entanglement of the wire during dispensing.

Hereinafter, the present invention will be explained based on an embodiment shown in the drawings.

In the present invention, when the wire 4 that has been wound and stored is supplied to the wire storage section 3 between the outer cylinder 1 and the inner cylinder 2 of the pail pack A from above the pail pack A, the wire 4 is In a pail pack winding wire dispensing device in which the wire 4 is twisted in advance so as not to be twisted, between the outer cylinder 1 and the inner cylinder 2 of the pail pack A above the wire 4 stored in the pail pack A, A wire dispensing ring 5 is disposed, and the wire dispensing ring 5 forms annular gaps 6a, 6b with a predetermined opening width between it and the outer cylinder 1 of the pail pack A, and has a predetermined opening width for leading out the stored wire 4. An upper ring 7a and a lower ring 7b arranged at a predetermined interval, and an intermediate guide member extending upward from the lower ring 7b and arranged at an angle so as to approach the center side of the pail pack A as it goes upward. 7c
...and is becoming more popular.

To explain this in detail, the drawing shows an example in which the device of the present invention is applied to a pail pack A of wire for carbon dioxide arc welding.

This pale pack A has an inner tube 2 which is provided with a wire storage part 3 concentrically with the outer tube 1 and between the outer tube 1 and an inner tube 2 which is raised up from the periphery of the bottom plate 1a. It's summery.

Inside the pail pack A configured as described above, a pail pack winding device (not shown) is installed.
By rotating the wire with a guide or the like, the center line of the pail pack A is twisted while giving a twist in the opposite direction to the twisting at the time of paying out so that the wire does not twist when being paid out.
'The wire 4 is supplied from above and wound and stored in the wire storage part 3 sequentially from the bottom upwards, and the pail pack A storing the wire 4 extends from the outer cylinder 1 to the inner cylinder 2 with a lid (not shown). It is shipped packed with the top opening closed.

When a user wishes to use the wire 4, the user removes the lid from the packaged pail pack A and then attaches the wire payout device of the present invention as shown in the drawings.

That is, the wire dispensing ring 5 has an upper ring 7 attached to an upper rib member 8 extending in a cross shape in the diametrical direction.
The wire dispensing ring 5 is constructed by integrally assembling the lower ring 7b to the lower end of the intermediate guide member 7c, whose upper end is integrally assembled to the upper rib member 8. 8 is placed on the upper end of the inner cylinder 2 of the pale pack A, and the center ring 9 hanging down from the upper rib member 8 is fitted into the upper part of the inner cylinder 2.

Wire dispensing ring 5 attached to the upper part of the inner cylinder 2
The upper ring 7a is arranged close to the outer cylinder 1 to form an annular gap 6a therebetween, and the lower ring 7b is arranged close to the outer cylinder 1 of the pale pack A. It is arranged close to the outer cylinder 1 to form an annular gap 6b.

The wire 4 stored in the wire storage section 3 of the pail pack A is discharged by being led out through the annular gap 6b and the annular gap 6a.

Further, as shown in FIG.
The wire 4a before being led out of the annular gap 6b between the outer cylinder 1 and the outer cylinder 1 is always sprung upward by its twisting force, and by releasing the twisting force, the wire 4 is pulled up into the upper ring. It is designed so that it does not jump upwards above 7a.

Note that the opening width of the annular gap 6a and the opening width of the annular gap 6b may be approximately the same size, but when drawing out the wire 4 from the wire storage section 3, a certain amount of drawing resistance is required over the entire circumference. Since the pull-out resistance is generated when the wire 4 rubs against the lower ring 7b, the inner wall of the outer cylinder 1 of the pale pack A, and the upper ring 7a, it is desirable that the opening size is, for example, about 50 mm or less. The opening width of the annular gap 6a is about 5 mm or more larger than the opening width of the annular gap 6b, and the vertical distance between the upper ring 7a and the lower ring 7b is about 150 mm or more, for example, 200 mm, and further,
The distance between the upper surface of the wire 4 stored in the wire storage part 3 and the lower ring 7b should be at least a gap that does not interfere with the wire 4 being pulled out smoothly.

Further, a frustoconical wire dispensing hood 11 is removably placed on the outer cylinder 1, and a guide tube 12a is provided at the top of the wire dispensing hood 11, and a guide tube 12a is provided at the top of the wire dispensing hood 11, and a guide tube 12a is provided at the top of the wire dispensing hood 11. The wire 4 thus led out passes through guide tubes 12a and 12b and is sent to a welding torch 15 by feed rollers 14 and 14 which are rotationally driven by a motor 13.

Note that the lower end flange 11a of the wire dispensing hood 11 is placed on the upper end of the outer cylinder 1,
It is fixed to the upper end flange portion 1b of the outer cylinder 1 by a removable fixing ring 16.

In the embodiment configured as described above,
The wire 4 wound and stored in the wire storage part 3 of the pail pack A is pulled out through the annular gaps 6b and 6a, and is further pulled out through the guide tubes 12a and 12.
b, and is sent to the welding torch 15 by feeding rollers 14, 14, where it is used as a supplementary material for carbon dioxide arc welding.

Thus, the wire 4 stored in the wire storage part 3 of the pail pack A is wound up in the wire storage part 3 sequentially from the bottom, but the wire 4 in the pail pack A is wound once per rotation. Because of the twist, if the tip of the wire 4 is left unattended, it will naturally spring upward due to the twisting force of the wire 4. In order to pull out the wire 4 upwardly along the inner wall of the outer cylinder 1 of the pail pack A without getting tangled, the wire dispensing ring 5 of the present invention
Therefore, one wire 4 is
As shown in the figure, the lower ring 7b and upper ring 7a constituting the wire dispensing ring 5 are brought into contact with the inner wall of the outer cylinder 1 of the pail pack A, and are pulled out toward above the center line of the pail pack A. Therefore, when the wire 4 is pulled out, a slight resistance is generated, which prevents the wire 4 from rotating around the upper ring 7a and the lower ring 7b.Moreover, the wire 4 is pulled upward, so that the wire 4 is pulled out. The ring diameter of the wire 4 housed inside the wire is about to become smaller. Originally, the wire 4 is a straight wire with little curl and is housed in the pail pack A with a certain ring diameter, so there is always a force in the wire 4 that tries to increase the ring diameter. are doing. The upper ring 7a and the lower ring 7b prevent the ring from springing upward due to the twisting of the wire 4 by overcoming this force and reducing the diameter of the ring. If even one of the upper ring 7a or the lower ring 7b is removed, the resistance to pull out the wire 4 will be reduced, the wire 4 will easily turn around the upper ring 7a or the lower ring 7b, and the wire 4 will be inside the pail pack A. The ring diameter of the stored wire 4 becomes large, and it passes through the upper ring 7a or the lower ring 7b and springs upward, causing tangles.

In the above embodiment, the wire dispensing ring 5 is constructed by welding together an upper ring 7a, a lower ring 7b, an intermediate guide member 7c, and an upper rib member 8, which are made of wire rods. However, the present invention is not limited to this, and may be formed by processing a steel plate.

As explained above, in the present invention, the wire stored in the pail pack is pulled out upwardly of the pail pack while hitting the lower ring, the upper ring, and the inner wall of the outer cylinder of the pail pack, which constitute the wire dispensing ring. Resistance is generated, and the force of the wire turning around the upper and lower rings is inhibited, and the wire is pulled upward, so that the ring diameter of the wire stored in the pail pack tends to become smaller. The upper ring and the lower ring prevent the wire from springing upward, thereby effectively preventing the wire from becoming tangled during payout.

Furthermore, regarding the function and effect of the intermediate guide member, since the wire inside the pail pack always has an inherent force that tends to spring upward, the wire formed by the intermediate guide member, the inner cylinder of the pail pack, and the upper rib member. In the trapezoidal space, the annular gap between the lower ring and the outer cylinder is constantly made to spring upward by the twisting force of the wire, and the twisting force is released. This has the effect of preventing the wire from rising above the upper ring.

Furthermore, the wire dispensing ring used in the device of the present invention can be produced relatively easily and inexpensively by processing and forming wire rods or steel plates, and the wire dispensing hood has the advantage that the wire dispensing hood used in the past can be used as is. be.
