Description

[Detailed description of the invention] This invention involves twisting the welding wire from the pail pack, which is stacked in a loop shape and storing the welding wire, and then taking it out smoothly and continuously to the outside upper part of the pail pack without any tangles. Regarding equipment.

The above-mentioned pail pack is used as a large-capacity welding wire storage container. To take out the wires from the pail pack, take out the wires from the top of the wire stack to the outside of the pail pack, and bend them with a wire straightener if necessary. is removed, and then guided through a conduit tube to a welding torch by a wire feeding mechanism provided on the welding torch side. Various take-out devices have been devised to smoothly take out the welding wire from the pail pack, but all of them are difficult to take out continuously over a long period of time, especially when high-speed take-out is performed in response to high-efficiency welding. This is not satisfactory as tangles etc. occur.

In particular, welding wire stored in recent pail packs that are twisted within the elastic limit, for example, with a twist of 360° per turn of the wire, may cause the wire to twist within the pail pack. There is an inherent force that tends to spread toward the outer circumference, and when the wire is released, it has a tendency to jump upward along the inner wall of the outer cylinder of the pail pack, which prevents tangles when removing the wire. , tangles, etc. appear more prominently. For this reason, conventionally, a ring-shaped presser member made of a rigid body is placed on top of a wire stack that is stacked and stored in a loop between the inner cylinder and the outer cylinder of a pail pack, and the wire is pressed from above. A method has been proposed to eliminate this jump. However, in this method, since there is a gap between the annular holding member and the inner wall of the outer cylinder, the wire may jump up from the gap and become tangled, causing problems such as tangles and interrupting wire removal. If the wires in the pail pack become tangled and tangled during welding, the wires will not be fed to the welding torch, making it impossible to continue the welding operation, or even if it is possible, welding defects will occur.

The present invention has been made in order to eliminate the drawbacks of the prior art described above, and provides a device for taking out a twisted welding wire that can smoothly take out the twisted wire without getting entangled or tangled when taking out the twisted wire from a pail pack. The purpose of the device is to take out welding wire from a pail pack in which welding wires are stacked and stored in a twisted state. a ring-shaped holding member provided in the center thereof, and a string member having an upper end fixed to the outer cylinder of the pale pack and hanging between the inner wall of the outer cylinder and the wire laminate, the string member being attached to the holding member. It is inserted through a hole provided.

The present invention will be described below based on embodiments shown in the drawings. Of course, the following embodiments do not limit the present invention, and various embodiments can be considered as appropriate without departing from the gist of the present invention.

Fig. 1 is a cross-sectional view showing the welding wire take-out device of the present invention in use, Fig. 2 is a cross-sectional view taken along the line A-A' in Fig. 1, and Fig. 3 shows the main parts. This is a cross-sectional side part. Pail pack 1 is inner cylinder 2
(the inner cylinder may be omitted) and an outer cylinder 3, which are arranged in a concentric circle, and a welding wire stacked in a loop is stored in the space between the inner and outer cylinders. Ru. W′ indicates a loop-shaped laminate of this welding wire. The lower end of the inner cylinder 2 is fixed to the bottom plate of the outer cylinder 3, the open upper end of the bottomed outer cylinder 3 is closed with a conical lid member 4, and the abutting part of these members 3 and 4 is connected to a fastening band 5. connected by. A hole is made in the center top of the lid member 4 for the wire W to pass through,
It is connected to conduit tube 6. Note that the wire straightener 7 is removably attached in alignment with the hole as necessary.

A flexible string member 8 is attached to the upper part of the inner wall of the outer cylinder 3.
A plurality of wires, four in this example, are attached at predetermined intervals with their upper ends 8' fixed, and the wire laminate is
A ring-shaped holding member 9 made of a rigid body and having a wire take-out hole in the center is placed on the upper part of W'. The annular presser member has holes 10 formed in the vicinity of the outer periphery of the presser member in the same number as the string members 8, that is, four holes, and the string members 8 have their upper ends fixed to the upper part of the outer cylinder 3. is inserted through the hole 10 of the holding member 9 and is suspended between the inner wall of the outer cylinder 3 and the outer circumference of the wire laminate W'. As shown in FIG. 2, the presser member 9 has holes 10 in its outer circumference
Together with the string member inserted into the ring, the wire along the inner wall of the outer cylinder 3 is prevented from jumping up, and a predetermined distance 〓B is formed between the inner periphery and the outer wall of the inner cylinder 2. The loop-shaped welding wire W, which is laminated and stored between the inner and outer cylinders of the pail pack in a rotating manner, is taken out to the upper side and outside of the pail pack.

The positional relationship between the annular presser member 9 and the string member 8 is as shown in FIG.
It is necessary that the string member 8 is inserted through the
With this configuration, even a twisted wire can be taken out from the annular gap B without any inconvenience. In other words, the twisted welding wires stacked and stored in a loop between the outer cylinders of the pail pack have an inherent force that tends to untwist them and always tend to spread toward the outer periphery. When taking out the wire, the wire tends to jump up randomly along the inner wall of the outer cylinder, but in the present invention, the upper outer periphery of the wire laminate W' is blocked by the string member 8 and the presser member 9, so that the wire does not jump up or jump out. This prevents the occurrence of wire loss and enables smooth wire removal from the gap B. Note that the wire laminate
The upper part of W' gradually descends as the storage wire is consumed and reduced, and the presser member 9 placed on the upper part also descends while passing the string member 8 through the hole 10. This continues until the member 9 completes its descent, maintaining the positional relationship shown in FIG.

The string member 8 is sandwiched between the inner wall of the outer cylinder 3 and the wire laminate W', passed through the hole 10 of the pressing member 9, and then its upper end is fixed directly to the upper part of the inner wall of the outer cylinder 3 with adhesive tape or adhesive. It is fixedly attached by appropriate means, and its lower end is provided so as to reach the bottom plate of the pail pack. Although this string member 8 resists the springing up of the wire above the outer periphery of the wire laminate W' due to the clamping force between the inner wall of the outer cylinder 3 and the wire laminate W' and its own weight, the presser member 9 is lowered. When it comes to the vicinity of the lowest end, the clamping force and dead weight decrease and the ability to prevent the wire from jumping up becomes weaker, so it is preferable to fix the lower end of the string member 8 to the lower end of the inner wall of the outer cylinder 3. Further, the shape and material of the string member 8 are not particularly limited, but it should have a flat cross section, such as a cloth tape or a steel strip, so as not to hinder the storage of the wire.

As described above, the annular presser member 9 is placed on the upper part of the wire laminate W' and descends together with the upper part of the wire laminate W', while the string member 8 is attached to the outer periphery of the presser member.
At the same time, the lower part is intended to prevent the wire W from jumping up due to the weight of the holding member, and its material is not limited, but may be made of steel or synthetic resin such as vinyl chloride, and may also be made of hardboard or cardboard. . Further, in the above embodiment, the hole provided in the presser member 9 is a hole bored in the presser member, but the hole is not limited to this. Alternatively, the string member may be inserted through the wire take-out hole in the center of the presser member, without departing from the spirit of the present invention. Further, in the above embodiment, the inner circumferential portion of the presser member is configured to form an annular space between the inner circumferential portion of the presser member and the outer wall of the inner cylinder, but the inner circumference of the presser member is not limited to this. An elastic member may be provided at the part so as to contact the outer wall of the inner cylinder, and in this way, it is possible to prevent the subsequent wires from jumping out in a disorderly manner when the wire is taken out between the inner peripheral part of the presser member and the outer wall of the inner cylinder. There are advantages.

As is clear from the above description, the inner tube 2 does not have any special function for the wires that are twisted and stored in a stacked manner. This is true when storing the wires in a stacked manner and when removing them from the stack. Therefore, in this case, the inner tube 2 may be removed.

As explained in detail above, in the present invention, a holding member is placed on top of the twisted wire stack and housed in a stack inside a pail pack. This structure includes a string member that is inserted through a hole in the pail pack and hung vertically between the inner wall of the outer cylinder and the outer circumference of the wire laminate. The wire can be taken out from the wire take-out hole in the center of the presser member while being smoothly rotated without causing any inconvenience.

The device of the present invention is effective in taking out welding wires that have been twisted and stored in layers in a pail pack, and it is possible to smoothly and continuously take out the wires without interrupting welding work. Despite its simple configuration, it is an extremely practical device.
