Abstract

PROBLEM TO BE SOLVED: To prevent interwinding and a tangle from generating when a wire is taken out of a vessel by providing elastic members contacting with the inner wall of a pail vessel on the three positions of the outer circumferential part of a doughnut-like presser plate, and providing string members connecting together the doughnut-like presser plate and the bottom part of the vessel and winding members therefor. SOLUTION: Elastic members 6 contacting with the inner wall of a pail vessel 1 are provided on the three positions (aboout 120 deg. intervals) of the outer circumferential part of a doughnut-like presser plate 5. Hereby, when a wire W is pulled up, there is no possibility of jumping up of a succeeding wire loop. Winding members 8 are arranged on the two positions (about 180 deg. intervals) of the inner circumferential part of the doughnut-like presser plate 5, it is connected to one end of a string member 9, and the other end of the string member is locked with a hook 15. The pail vessel 3 and the presser plate 5 are always pulled from each other through the string members 9, and hence the loop does not get up and the presser plate 5 is not lifted. Hereby, there is no possibility that the loop is jumped into a columnar cavity 7 so as to generate interwinding or a tangle.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a welding wire loaded material in which a welding wire such as a twisted solid wire or a flux-cored wire is wound in a loop and housed in a pail container.

[0002]

2. Description of the Related Art Pail containers are used as containers for storing large-capacity welding wires (hereinafter referred to as wires). The wire of the pail container is taken out in order from the upper part of the wire stack to the upper part of the pail container and led to the welding torch through the conduit tube by the wire supply device.

[0003] A pail container having an inner cylinder and an outer cylinder, and having a double cylindrical shape for accommodating a wire in a space between the inner and outer cylinders,
Alternatively, there is a type in which a ring-shaped pressing plate is mounted on a single cylindrical shape that does not include an inner cylinder and stores a wire in an outer cylinder. Further, as a wire take-out position, there is a method of taking out the wire from the inner hole of the ring-shaped press plate and from the outside of the press plate along the inner wall of the pail container.

[0004] Among them, as a technique for taking out a wire along a single cylindrical pail container and the inner wall of the container, there is Japanese Patent Publication No. 61-42706, for example. This will be described with reference to FIG. 4. In the space inside the pail container 1 composed of the outer cylinder portion 2 and the bottom portion 3, the wires are stacked and stored in a loop shape, and the upper surface of the wire stack 4 is used to prevent the wires from jumping up. Holding plate 5 is placed. That is, the pail container 1
Since the wire stored in the wire is twisted within the limit of elasticity, for example, 360 ° twist per loop, the wire has a restoring force inside the pail container and tends to jump upward. The wire laminate 4
The holding plate 5 made of a rigid body is placed on the upper surface, and the wire is pressed from above.

[0005] The wire W is connected to the outer periphery of the holding plate 5 and the pail container 1.
Is lifted upward from the gap with the inner wall of the pail container, but there is a possibility that the subsequent wire loop may jump randomly along the inner wall of the pail container 1 from this gap. An elastic member 6 is provided so as to be able to be pulled up one loop at a time.

When the wire W is taken out of the pail container 1, the loop of the wire W immediately below the holding plate 5 is loosened and spread by the lifting force, and the wire W rotates from the gap between the holding plate 5 and the inner wall of the outer cylinder 2. To rise. Normally, the wire is not squeezed in the inner circumferential direction and does not protrude into the columnar cavity 7 inside the wire laminated body 4. However, since the upper surface of the laminated body 4 is in a complicated uneven state in which wire loops are densely layered, it is lifted up. The intended wire may be caught on a subsequent wire. Then, the spread to the outer circumference of the wire loop is stopped, and conversely, it is narrowed to the inner circumference. When the loop diameter is reduced to a certain extent and the loop diameter is reduced, the loop rises and raises the holding plate 5 to create a space. In this case, the effect of holding down the wire of the holding plate 5 is lost, so that the wire loop following the upper surface of the laminated body 4 freely jumps and ramps up, and the loop falls into the columnar cavity 7 at the center, causing entanglement and smoothing. Wire removal becomes impossible.

Japanese Unexamined Utility Model Publication No. 58-170344 discloses a technique for solving the above problem. FIG. 5 shows an example of the technology described above. As shown in FIG.
Is arranged on the inner periphery of the wire stack 4, one end is fixed to the bottom 3 of the pail container 1, and the other end is fixed to the back surface of the wire holding plate 5 in a state of being pulled above the pail container 1.
As the wire W decreases, the thickness of the wire laminate 4 becomes thinner, and the contraction force of the belt 10 is applied to the wire pressing plate 5,
The wire holding plate 5 is urged toward the bottom of the pail container. Therefore, even when the wire W being pulled is caught on a subsequent wire, the pressing plate is not lifted, so that the wire can be smoothly pulled out while preventing the wire from jumping up.

[0008]

However, in the above technique, as shown in FIG. 6, when the wire W in the pail container 1 becomes small, the rubber belt 10 as an elastic member is in a completely contracted state, and Cannot be urged further toward the bottom of the pail container, and the holding of the wire W becomes ineffective. Therefore, the wire on the upper surface of the laminated body where the holding of the holding plate has been removed is twisted and stored, so that the wire jumps upwards in an attempt to restore it, and the wire is entangled and the following wire passes through the elastic member to form a plurality of loops. There is a case where the above is pulled out and the appearance is caused.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art, and when the wire is taken out of the pail container, the loop falls into the columnar cavity or the presser plate and the inner wall of the pail container are connected. Since the plurality of loops are simultaneously pulled out from the gap, the load of the welding wire that enables the feed to the weld portion smoothly without causing entanglement until the wire in the pail container runs out is reduced. The purpose is to provide.

[0010]

That is, the gist of the present invention is to provide a loop-shaped welding wire laminated and housed while twisting the welding wire so as to form a cylindrical cavity in the center of the pail container. A donut-shaped holding plate having an elastic member abutting on an inner wall of the pail container at at least three places on an outer peripheral portion thereof and being placed on a wire in the storage container so as to be able to descend, and at least two places inside the holding plate; And a winding member for accommodating one end of each of the string members and maintaining a tensioned state of the string members as the holding plate descends. Things. In this case, the winding member for accommodating the string member is also characterized in that a leaf spring is used.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a charge for a welding wire according to the present invention. FIG. 1 is a cross-sectional view showing a state in which a wire stored in a pail container 1 is taken out. A twisted wire is stacked and stored in a loop shape inside the pail container 1.
Reference numeral 4 denotes a laminate of the wires, and reference numeral 7 denotes a columnar cavity formed in the laminate 4. A donut-shaped holding plate 5 is placed on the upper surface of the laminate 4 to prevent the wire from jumping up.

Further, since the elastic member 6 which comes into contact with the inner wall of the pail container 1 is provided at at least three places (at intervals of about 120 degrees) on the outer peripheral portion of the donut-shaped holding plate 5, the wire W
Subsequent wire loops do not jump up when the is pulled up along the inner wall of the pail container. Elastic member 6 is 3
If it is less than the location (at an interval of about 180 degrees and one location), when it is caught by a subsequent wire on the surface of the laminated body 4, it is pulled up simultaneously from the gap between the inner wall of the pail container and the holding plate 5, causing entanglement.

Although the sponge, synthetic rubber, natural rubber, plastic, or the like is used as the elastic member 6 on the outer peripheral portion of the donut-shaped holding plate 5, the same can be achieved by using another flexible material.

Further, a winding member 8 is arranged at at least two places (about 180 degrees apart) on the inner peripheral portion of the donut-shaped holding plate 5, and one end of a string member 9 is connected to the winding member 8. I have. A hook 15 is fixed to the bottom 3 of the container 1, and the other end of the string member 9 is locked to the hook 15.

FIG. 2 is an enlarged sectional view showing a state in which the winding member 8 is fixed to the holding plate 5. A leaf spring 1 is attached to a shaft 12 fixed to an outer frame of the winding member 8 at a central portion of the winding member 8.
One end of 3 is fixed and housed in a spring shape. The other end is connected to the string member 9 at the joint 14. String member 9
Is pulled out from the winding member 8 and is engaged with the hook 15 of the bottom 3 of the pail container through the through hole 11, so that the leaf spring 13 is wound around the shaft 12. Since the plate spring 13 wound around the shaft 12 exerts a force that spreads outward, a force acts to pull the string member 9 from the bottom 3 of the pail container, that is, to store the string member 9 in the winding member 12. Therefore, the tensile force always acts between the bottom 3 of the pail container and the holding plate 5 to always hold the wire stack 4.

Since the winding member 8 for accommodating the string member 9 is provided, even when the wire W is taken out of the pail container 1 and caught by a subsequent wire and the loop is narrowed to the inner periphery, the holding plate 5 and the bottom portion of the pail container are formed. 3 is prevented by the string member 9 tied at least at two places, and is not further narrowed. Further, since the space between the bottom portion 3 of the pail container and the holding plate 5 is constantly pulled by the string member 9, the holding plate 5 is not lifted because the loop does not rise. Therefore, it is possible to prevent the loop from jumping and dropping into the central columnar cavity 7 to cause entanglement or entanglement.

Further, as shown in FIG. 3, even when the number of wires in the pail container 1 is reduced, the tension is maintained on the string member 9 and the holding plate 5 is pulled toward the bottom 3 of the pail container. Therefore, as described above, the loop does not jump and fall into the columnar cavity 7 at the center, and the wire is not removed from the pail container 1 because the wire is not leaked.

If the presser plate 5 and the bottom 3 of the pail container are connected to each other and the winding member 8 for accommodating the string member 9 is provided at one position, the tensile force between the bottom 3 of the pail container and the presser plate 5 is offset, and the presser plate 5 is lifted and the loop jumps, and a cylindrical cavity 7 in the center
When you fall into the garbage, dust and scum occur. Therefore, at least two winding members 8 are required. The cord member 9 may be a thin steel plate or a resin band such as polypropylene.

[0019]

The present invention will be described in more detail with reference to the following examples. JIS Z in a 650 mm inner diameter pail container
3312 YGW11 solid wire, wire diameter 1.
A 2 mm loop was formed by applying a twist of 360 ° per loop to a 300 kg stack, and as shown in FIG.
A donut-shaped holding plate 5 (outside diameter 630 mm, inside diameter 490 mm) provided with an elastic member 6 made of polyethylene and abutting on the inner wall of the pail container 1 was placed at an interval of 20 degrees. further,
A winding member 8 having a leaf spring 13 therein was attached to the holding plate 5 at three places, and fifty welding wire charges having a polypropylene resin string member 9 fixed to the bottom 3 of the pail container were prototyped.

The charges for the welding wires were sent to various welding work sites, and the state of entanglement and entanglement at the time of wire removal from the start of welding until the wires in the pail container disappeared was examined. No entanglement or entanglement occurred during removal from the pail container, and the product could be smoothly fed to the welded portion, which was a very satisfactory result.

[0021]

According to the loading of the welding wire of the present invention,
When removing the wire from the pail container, the loops fall into the cylindrical cavity and multiple loops are pulled up simultaneously from the gap between the holding plate and the pail container, and the occurrence of tangling causes the wire in the pail container to disappear , And can be smoothly fed to the weld.
