Description

[Detailed description of the invention] The present invention relates to a pail pack equipped with a wire drawing jig, and in particular, an annular jig main body with a gap formed between the inner cylinder or the outer cylinder of the pail pack to take out the wire. is arranged with a space between it and the coiled wire, and an elastic body that comes into elastic contact with the inner cylinder or outer cylinder on the side where the gap is formed is fixed to the jig main body, and the elastic body is pulled out to the outside in the space. At the same time, the elastic body prevents the middle part of the wire from being pulled out from the gap by being dragged by the wire that is correctly taken out from the gap against the bias of the elastic body. to be able to be smoothly pulled out sequentially from the end.

A pale pack has a coiled wire concentrically housed between an inner tube and an outer tube, and the wire is pulled out from one end for use. In order to be able to pull out the wire without twisting it during use, it is generally done in advance in the winding process to give the wire a twist in the opposite direction to the twist that occurs when it is pulled out. Such a winding means is particularly suitable when a wire forming a welding rod for gas-shielded arc welding is stored in a pail pack as the wire rod.
If the wire rod (the wire that forms the welding rod) is pulled out in a twisted state and fed to the welding machine as it is, the bead will meander, so to prevent this,
This is because it is necessary to pull out the wire without twisting it and feed it as is to the welding machine. Therefore, as described above, a force that tends to spring out in the axial direction of the coil always acts on the wire, which has been given a twist in the opposite direction to the twist that occurs when it is pulled out. Therefore,
If a part of the wire jumps out of the pail pack due to this force, a kink or the like will occur in the middle of the wire being drawn out, making it impossible to draw it out smoothly.

Therefore, in order to smoothly draw out the wire, a pail pack equipped with a wire drawing jig as shown in FIGS. 1 and 2 has already been proposed. That is, 1 is a pale pack consisting of an inner cylinder 1a and an outer cylinder 1b concentric with the inner cylinder 1a.
Between the inner tube 1a and the outer tube 1b, a wire rod 2 which has been wound up in the winding process with a twist in the opposite direction to the twist that occurs at the time of pulling out is stored in a coil shape. The bottom of is closed.
3 is a drawer jig, which is the drawer jig 3 in Fig. 1.
is made of an annular plate, and forms a gap 4 between the inner periphery of the drawer jig 3 and the outer periphery of the inner cylinder 1a for taking out the wire 2, and constantly keeps the upper surface of the coiled wire 2 due to its own weight. This prevents the wire rod 2 from jumping out. Further, the drawing jig 3 shown in FIG. 2 includes a plurality of rings made of wire,
It consists of a plurality of connecting wires that connect these, which are engaged with the upper end of the inner cylinder 1a and form a gap 4 between the outer periphery of the ring and the inner periphery of the outer cylinder 1b,
This prevents the wire rod 2 from popping out.

However, such a drawer jig 3 has the following problems. That is, in the case of the drawing jig 3 shown in FIG. 1, if the drawing jig 3 is light, the drawing jig 3 is
If the wire rod 2 is dragged by the wire, a part of it will float up and the entire wire will be tilted, causing the wire rod 2 to jump up and increase the resistance to pull out.Also, if the drawer jig 3 is heavy, Since the wire rod 2 is always in close contact with the upper surface of the wire rod 2, the movement of the uppermost part of the wire rod 2 is restricted, causing problems such as kinks and small bends in the wire rod 2 being drawn out. Furthermore, wire rod 2
If there is any disturbance in the winding state of the wire rod 2 due to a defect in the winding process or vibrations during transportation of the pale pack 1, the wire rod 2 may be dragged by the wire rod 2 being pulled out from the gap 4. Even wire rods 2 that should not be pulled out are pulled out together, causing problems such as kinks and small bends in the wire rods 2.

Furthermore, in the case of the drawer jig 3 shown in FIG.
Since it is made of wire, it will deform when used for a long period of time, and if used as is, it will cause kinks and an increase in the pulling resistance. Not only does it take a lot of effort to fit together, but the wire 2 inside the pail pack 1 may jump out during that time.
Since this drawing jig 3 is relatively expensive, there is a problem in that the cost is high for customers who use the non-twisted pail pack wire on a one-off basis.

The present invention was made to solve these conventional problems, and its purpose is to unravel the coiled wire and then connect the drawer jig to the inner or outer cylinder. The wire rod is pulled out from the gap between the wire rods, and at this time, the wire rod is handled so that the middle part of the wire rod is not pulled out from the gap,
The purpose is to enable the wire to be smoothly pulled out sequentially from its end.

That is, the pail pack of the present invention, which is equipped with a wire drawing jig, pulls the wire wound into a coil,
In a pail pack that is stored concentrically between an inner cylinder and an outer cylinder, a ring-shaped jig main body that prevents the wire from jumping out is attached to the coil while a gap is formed between the inner cylinder or the outer cylinder to take out the wire. It is characterized in that an elastic body is disposed with a space between the jig body and the jig body, and is fixed to the jig body to make elastic contact with the inner cylinder or the outer cylinder on the side where the gap is formed.

Next, the present invention will be explained based on the embodiments shown in FIG. 3 and below.

3 and 4 are diagrams showing the first embodiment of the present invention, and the pail pack 1 consisting of the inner cylinder 1a and the outer cylinder 1b and the wire rod 2 housed therein are the same as in the conventional example. be. Reference numeral 3 denotes a drawer jig. The drawer jig 3 has a jig main body 3a made of an annular plate, and a wire rod is disposed between the inner circumference of the jig main body 3a and the outer circumference of the inner cylinder 1a. In addition, there is almost no gap between the outer periphery of the jig main body 3a and the inner periphery of the outer cylinder 1b, so that the wire 2 does not come out from there. The jig main body 3a includes an elastic body 3b whose tip comes into elastic contact with the outer peripheral surface of the inner cylinder 1a.
An engagement piece 3 whose base end is fixed and whose tip engages with the upper end surface of the outer cylinder 1b to position the jig main body 3a.
The proximal end of c is fixed. Thus, the jig body 3a
The elastic body 3b and the engaging piece 3c constitute a drawer jig 3. The jig main body 3a is constituted by a plate made of an appropriate material such as steel, wood, plastic, paper, etc., and the elastic body 3b is constructed by cutting plastic tape or the like into an appropriate length, and the engaging piece 3c is
It is constructed by cutting a tape-shaped steel plate to an appropriate length and then bending it.

Such a drawer jig 3 is capable of removing the stored wire rod 2 from
The jig main body 3a has a weight that prevents a part or the whole of the jig main body 3a from moving upward even if a force that tries to spring out in the axial direction of the coil is applied, and the engagement piece 3c has a weight that prevents the jig main body 3a from moving upward.
A is suspended and supported, and the lower surface of the jig main body 3a,
A space 5 is formed between the coiled wire rod 2 and the upper surface thereof. The elastic body 3b and the engagement piece 3c are integrated, and the part protruding inward of the jig body 3a is the elastic body 3b.
The engaging pieces 3c may be formed by the outwardly protruding portions of the jig main body 3a.

Therefore, the wire rods 2 are pulled out from the pale pack 1 one after another. The wire 2 is drawn out from the end of the pail pack 1 through the gap 4. At this time, even if a force acting on the wire rod 2 housed in the pale pack 1 tends to spring out in the axial direction of the coil, the jig main body 3a prevents the springing out. In addition, a part of the wire rod 2 coiled in the pail pack 1 is caught on the wire rod 2 that is being pulled out and is moving toward the gap 4, and is pulled up together toward the gap 4. However, since there is a space 5 between the coiled wire 2 and the jig main body 3a, the wire 2 that is being pulled out and wraps around in the circumferential direction of the space 5 may be wire rod 2
When the wire rods 2 are separated from each other, the hooks between the wire rods 2 are loosened.

Therefore, the only wire rod 2 that passes through the gap 4 is the wire rod 2 to be pulled out, but if the wire rod 2 cannot be unraveled completely in the space 5, the wire rod 2 that should not be pulled out will be caught in the wire rod 2 to be pulled out. 2 also passes through gap 4. At this time, the elastic body 3b prevents the wire 2, which should not be pulled out, from rising. That is, the elastic body 3b uses its elastic force to treat the wire 2 to be drawn and the wire 2 that should not be drawn, but the wire 2 to be drawn is loaded with a tensile force for drawing. The wire 2 that is not supposed to be pulled out is pulled upward by overcoming the handling of the elastic body 3b, and the tensile force for pulling it out is not applied, so this wire 2 is moved upward due to the handling by the elastic body 3b. is prevented.

Thus, the wire 2 is pulled out from the pail pack 1 smoothly and reliably without kinking.

Furthermore, as a means for engaging the tip of the engagement piece 3c with the upper end of the outer cylinder 1b, the tip of the engagement piece 3c is connected to the upper end of the outer cylinder 1b.
If the structure is such that it is simply hooked onto the upper end of b, the drawer jig 3 can be easily attached and detached when replacing the pail pack 1.

5 and 6 are diagrams showing a second embodiment of the present invention, in which the structure of the drawer jig 3 is reversed between the inside and outside. That is, a gap 4 is formed between the outer periphery of the jig main body 3a and the inner periphery of the outer cylinder 1b, while the inner periphery of the jig main body 3a and the outer periphery of the inner cylinder 1a are kept as close as possible. , the tip of the elastic body 3b is connected to the inner cylinder 1a
The tip of the engaging piece 3c is in elastic contact with the inner peripheral surface of the inner cylinder 1a.
The wire rod 2 is pulled out through a gap 4 formed on the outer periphery of the jig main body 3a. The other configurations and operations are the same as those of the first embodiment.

In these embodiments, the jig main body 3a is made of a plate material, but the cross-sectional shape in the thickness direction may have another shape as long as the effect is the same as described above.
Further, the elastic body 3b and the engagement piece 3c may also have other shapes as long as they have the same effect as described above, and further,
Of course, these numbers can be increased or decreased as appropriate.

As explained above, according to the present invention, while a gap is formed between the inner cylinder or the outer cylinder of the pail pack to take out the wire, the annular jig main body is connected to the coiled wire with a space between it and the coiled wire. An elastic body that came into elastic contact with the inner cylinder or outer cylinder on the side where the gap was formed was fixed to the jig main body. Therefore, in the space,
Since the wire just before being drawn out can be unraveled, the wire that should not be drawn out remains in the pail pack, separated from the wire that is to be drawn out. Furthermore, when a wire rod that should not be pulled out passes through the gap while being caught on the wire rod being pulled out, the elastic body handles the wire rod and prevents it from moving upward. Therefore, according to the present invention, the wire rods in the pail pack can be smoothly and accurately drawn out one after another from the ends thereof.
