[0001]
BACKGROUND OF THE INVENTION
The present invention includes a welding wire that is laminated in a loop shape and in a cylindrical shape between a container and an inner cylinder inside the container, and a wire pressing jig placed on the upper surface of the wire laminate. The present invention relates to a welding wire with a container for pulling out a working wire in the container axial direction.
[0002]
[Prior art]
As is well known, in automatic welding using an automatic welding apparatus such as an arc welding robot, a large capacity welding wire (for example, steel welding) is used in a vessel in order to improve the welding work efficiency by reducing the replacement frequency of the welding wire. For welding, wire diameter of 1.2mmφ, 100-300kg, for aluminum or aluminum alloy welding, wire diameter of 1.2mmφ, 50-150kg) is laminated in a loop and cylindrical shape (thick cylindrical shape) and stored The container welding wire thus formed is used. In such a welding wire with a container, a welding wire (hereinafter simply referred to as “welding wire” in the direction perpendicular to the laminating surface, that is, the axial direction (container axial direction) of the wire laminate having a cylindrical shape (thick cylindrical shape)). (Referred to as “wire”) is housed in the container so as to be pulled out, and when this wire is pulled out, twisting occurs in the circumferential direction of the wire. Therefore, in the case of a welding wire with a container, when the wire is stored in the container, the wire is twisted and stored in advance so that the twist after the wire is pulled out is offset and becomes zero. Yes.
[0003]
Thus, in the welding wire with a container, the wire is laminated and stored in a loop shape and a cylindrical shape in a state in which the container is previously twisted. For this reason, it is necessary to unwind one loop (one wheel at a time) from the last looped wire stored in the container welding wire, and pull it out in order. It is necessary to smoothly pull out the looped wire without adversely affecting the housed state of the pulled-out wire and causing trouble.
[0004]
Conventionally, a welding wire filling pail is disclosed in Japanese Patent Application Laid-Open No. 2000-202630 as a typical prior art relating to this type of container welding wire. FIG. 10 is a view showing a conventional welding wire filling pail, which is a sectional view perpendicular to the axis of the inner and outer cylinders.

Reference numeral 68 denotes a contact band that is provided along the outer peripheral edge of the ring 62 and contacts the inner peripheral surface of the outer cylinder 2.
[0006]
In such a welding wire filling pail (a welding wire in a container), the wire W drawn from between the inner cylinder 56 and the outer cylinder 52 is between the position near the inner cylinder 56 and the position near the outer cylinder 52. Although it repeatedly moves in a substantially zigzag shape, the shape of the plurality of guide pieces 64 corresponds to the movement at the time of pulling out such a wire, so that the wire pressing jig 60 is difficult to jump up. This prevents fine entanglement and entanglement from occurring in the wire being drawn out.
[0007]
On the other hand, in the case of a welding wire contained in a container, in order to prevent the entanglement between loop-shaped wires forming the wire laminate from being generated by vibration or the like that occurs during the transportation process, the wire laminate for fixing the wire laminate.

As a result, the cylindrical frame 46 descends while surrounding the inner cylinder 42 while extending the band-shaped rubber string 45 downward, and the cylindrical main body frame 44 is moved downward by the cylindrical frame 46 via the band-shaped rubber string 45. The wire laminate W ′ is fixed by pressing.
[0011]
[Problems to be solved by the invention]
However, in the above-described conventional welding wire filling pail (container welding wire), in the cylindrical space formed between the outer cylinder 52 and the inner cylinder 56, the wire W drawn from the wire laminate is preliminarily provided. There is a drawback in that the wire W rotates (rotates) due to the accumulation of the twisted plastic deformation when the twist is applied, thereby causing the wires W to be entangled with each other.
[0012]
Further, in the above-described conventional wire laminate restraining jig, a cylindrical main body frame to which an elastic body is attached, and a cylinder for abutting the elastic body to exert an elastic action in order to fix the wire laminate. Both the frame and the frame need to be attached for transportation or removed prior to the start of use at the welding site. was there.
[0013]
Accordingly, an object of the present invention is narrowed by forming a welding wire drawn out from a wire laminate between a wire lead-out space regulating cylindrical body and an inner cylinder by a wire lead-out space regulating cylindrical body. By passing through the wire drawing space, it is possible to prevent the welding wire drawn from the wire laminate from rotating, thereby reliably preventing the entanglement between the wires. It is an object of the present invention to provide a welding wire in a container that can be smoothly pulled out. Another object of the present invention is to construct a wire laminate restraining jig for fixing the wire laminate during transportation using the wire pull-out space regulating tubular member, An object of the present invention is to provide a welding wire with a container excellent in workability because it does not take time to attach and detach the body restraining jig.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the present invention takes the following technical means. The invention of claim 1 includes a container, an inner cylinder provided concentrically in the container, and a welding wire laminated in a loop and in a cylindrical shape between the container and the inner cylinder. A wire holding jig placed on the upper surface of the wire laminate, and in the container-containing welding wire for pulling out the welding wire in the container axial direction, it is disposed between the container and the inner cylinder, A wire for container-containing welding, comprising: a wire pulling space regulating cylindrical body that surrounds the inner cylinder with a space on the wire pressing jig and forms a narrowed wire pulling space. is there.
[0015]
According to a second aspect of the present invention, in the welding wire with a container according to the first aspect, the tubular body for regulating the wire drawing space is a polygonal tubular shape.
[0016]
The invention according to claim 3 is the wire-laden restraint treatment for fixing the wire laminate during transportation, wherein the tubular body for wire draw-out space regulation is used in the container-welding wire according to claim 1 or 2. It is also characterized by constituting the tool.
[0017]
According to a fourth aspect of the present invention, in the welding wire in a container according to the third aspect, the wire laminated body restraining jig is attached to the tubular body for wire drawing space restriction and the tubular body for wire drawing space restriction. And a cylindrical frame for fixing the wire laminate by pressing the wire pull-out space regulating cylindrical body downward through the elastic body. It is.
[0018]
A fifth aspect of the present invention is the container-welded welding wire according to the first, second, third, or fourth aspect, wherein the welding wire is aluminum or an aluminum alloy wire.
[0019]
The container-welding wire according to the present invention has a wire pressing jig having a plurality of wire pressing pieces that are elastically deformable and have an internal gear shape placed on the upper surface of the wire laminate, and further, A tubular body for regulating a wire drawing space having a tubular shape such as a polygonal tubular shape is placed on the plurality of wire pressing pieces formed. The wire pull-out space regulating cylindrical body descends together with the wire pressing jig as the wires forming the wire laminated body are sequentially drawn out and the wire laminated body gradually decreases. By this tubular body for wire pull-out space regulation, a thick cylindrical space between the container and the inner tube on the wire pressing jig is partitioned into the inside and outside, for example, the tubular body for wire pull-out space restriction and the inner tube Between these, a wire lead-out space is formed, which is a narrow cylindrical space compared to the case where the pull-out space regulating cylindrical body is not provided.
[0020]
And since this cylindrical body for wire lead-out space restriction is placed on a plurality of wire pressing pieces having an internal gear shape, the wire from the wire laminate is a wire in the radial direction between the container and the inner cylinder. When the wire presser piece located at the position closer to the inner cylinder side than the position of the drawer space regulating cylindrical body is elastically deformed, it is guided into the narrowed wire drawer space and comes into contact with the outer peripheral surface of the inner cylinder. Thereafter, the narrowed wire lead-out space is pulled upward.
[0021]
Thus, the wire which consists of the narrow cylindrical space which formed the wire pulled out from the wire laminated body between the cylindrical body for wire drawer space control, and an inner cylinder with the cylindrical body for wire drawer space regulation It passes through the drawer space. Thereby, according to the container-welded wire according to the present invention, when the wire is drawn, the wire drawn from the wire laminate is rotated due to accumulation of twisted plastic deformation when the twist is applied in advance. Without entanglement, it is possible to reliably prevent the entanglement between the wires.
[0022]
Further, according to the welding wire with a container according to the present invention, the wire pulling space regulating cylindrical body is provided and the wire laminated body is fixed during transportation using the wire pulling space regulating cylindrical body. Since the wire laminated body restraining jig for this purpose is also configured, it takes less time to attach and detach the wire laminated body restraining jig, and the workability is excellent.
[0023]
The container welding wire according to the present invention is particularly suitable for aluminum or aluminum alloy wires. Compared to steel wires, aluminum or aluminum alloy wires have a specific gravity of about 1/3 and are light and soft, so that they can move freely in the container, so a more appropriate welding wire in a container is required. . In particular, soft aluminum alloy wires (1000 series and 4000 series) need to be drawn out so as not to cause plastic deformation due to entanglement between the wires. According to the welding wire with a container according to the present invention, a wire pull-out space regulating cylindrical body is provided, and the wire pulled out from the wire laminated body is allowed to pass through a wire pull-out space composed of a narrowed cylindrical space. Therefore, even if the wire is aluminum or aluminum alloy, the wire drawn out from the wire laminate does not rotate in the wire drawing space, and it is possible to reliably prevent the entanglement between the wires and to make the wire smooth. A drawer can be made.

And the base end part extended in the perpendicular | vertical upper direction of these wire holding pieces 3b is adhering to the outer peripheral surface of the annular frame 3a. In FIG. 3, the proximal end portion of the wire pressing piece 3b is not shown.
[0028]
As shown in FIGS. 1 and 3, the wire pressing piece 3b does not form a centripetal shape toward the center of the circle of the container 1 (inner cylinder 2) in plan view, but from the wire laminate W ′. Inclined in the direction in which W is unwound (counterclockwise in FIGS. 1 and 3). In this way, by tilting the wire pressing piece 3b in a plan view, the wire W from the wire laminate W ′ is smoothly drawn in the unwinding direction.
[0029]
The annular frame 3a has a relatively thin ring shape, and is made of, for example, a laminated paper material. The wire pressing piece 3b is made of a thin sheet made of an elastic material. As the material of the elastic material of the wire pressing piece 3b, a material having an appropriate elasticity such as polyester resin, polypropylene resin, vinyl chloride resin, polycarbonate, polyethylene terephthalate (PET), and sufficient strength against repeated bending.

[0030]
Further, as shown in FIGS. 1, 2 and 5, on this wire presser piece 3b having an internal gear shape, in this embodiment, a hexagonal cylinder is formed, and a wire drawing space regulating cylinder having a required height. A state body 4 is placed. The wire pull-out space regulating cylindrical body 4 is disposed between the container 1 and the inner cylinder 2, and surrounds and narrows the inner cylinder 2 with a space on the wire pressing jig 3 (wire pressing piece 3b). Wire lead-out space wire S (shaded portion in FIG. 5) is formed. The drawer space regulating cylindrical body 4 is inscribed in the inner peripheral surface of the annular frame 3 a of the wire pressing jig 3. The thin wire-drawing space regulating tubular body 4 having a hexagonal tubular shape is made of cardboard, for example.
[0031]
In the welding wire with a container according to the first embodiment configured as described above, the wire W from the wire laminate W ′ is a tubular body 4 for regulating a wire drawing space in the radial direction between the container 1 and the inner cylinder 2. The wire presser piece located at the position closer to the inner cylinder 2 side than the position is elastically deformed to be guided into the narrowed wire lead-out space S. Next, the wire W from the wire laminate W ′ comes into contact with the outer peripheral surface of the inner cylinder 2 and then is pulled upward in the narrowed wire lead-out space S.
[0032]
As described above, the wire W drawn out from the wire laminated body W ′ is narrowed between the wire drawing space regulating cylindrical body 4 and the inner cylinder 2 by the wire drawing space regulating cylindrical body 4.

Cross-sectional area. The shape of the wire pull-out space regulating cylindrical body is preferably such that the free space ratio Sr is in the range of 60 to 80% in order to stably and smoothly pull out the wire without resistance. If it falls below this range, the resistance applied to the wire at the time of drawing becomes large. On the other hand, if it exceeds this range, the wire drawing space forming effect cannot be sufficiently obtained. If the shape of the wire pulling space regulating cylindrical body is an octagonal cylinder, the free space ratio Sr is 80%, and a good wire drawing space forming effect can be obtained. If the shape is a pentagonal cylinder, the free space ratio Sr is obtained. Is 50%, and a good wire drawing space forming effect cannot be obtained. Note that the shape of the wire pull-out space regulating cylindrical body is not limited to a polygonal cylindrical shape, and may be a cylindrical shape. In the case of a cylindrical wire pulling space regulating tubular body, the size may be set so that the free space ratio Sr is in the range of 60 to 80%. The polygonal tubular wire pulling space regulating tubular body is placed with its apex portion in contact with the inner circumferential surface of the container 1, specifically the inner circumferential surface of the annular frame 3 a of the wire pressing jig 3.
