Description

Wire Tangle Prevention Device for Welding {DEVICE FOR PREVENTING WELDING WIRE FROM TANGLING}

The present invention relates to a welding wire entanglement preventing device of a welding wire storage pack (Pail Pack) stacked in a large amount of the welding wire in a continuous loop (eccentric loop) in a large-capacity container, in more detail continuous loop A welding wire entanglement prevention device provided with a means for mutually controlling the welding wires stacked and received in a loop (Loop) to be naturally drawn between the interdigitated combs, and the subsequent welding wires are not raised and entangled with each other. will be.

Conventionally, in order to prevent entanglement of a large-capacity welding wire, an annular member is placed on the laminated surface of the welding wire stacked and stored in a container, and the device for drawing the welding wire into the annular member and the outside A device for drawing out is known.

As the inner drawing apparatus, Korean Patent Publication No. 87-1076, Japanese Patent Laid-Open No. 61-183057, and Japanese Patent Laid-Open No. 11-192552 are representative.

Korean Patent Publication No. 87-1076 is proposed to have a cushioning wing on an annular member so that the welding wire is consumed during the welding operation, and at the same time, it can naturally descend on the inner wall of the storage container, and Japanese Patent Laid-Open No. 61-183057 The arc is vertically attached to the inner wall of the storage container, and it is proposed to descend naturally on the band attached to the annular member, so that an empty space is formed between the upper lamination part of the welding wire and the annular member so that the welding wire is tangled. To prevent it. In particular, Japanese Patent Application Laid-Open No. 61-183057 considers that a welding wire jumps out of an annular member and becomes tangled.

However, in the drawing device of the inner side of the welding wire, the welding wire is drawn out into the lead-out hole of the annular member, and the problem of being drawn out to the subsequent welding wire is entangled with each other. In Korean Utility Model Publication No. 91-5819 and Japanese Patent Laid-Open No. Hei 4-133973, it was determined that the annular member was caused by the light weight, and the weight member was placed on the annular member. Could not control the welding wire.

In particular, Japanese Patent Laid-Open No. Hei 11-192552 attempts to control a subsequent welding wire drawn out by reducing the lead-out hole of the annular member. However, there are frequent situations in which subsequent welding wires are entangled with each other and do not come out through the small withdrawal holes of the annular member so that the welding operation is stopped.

As the external drawing device, Japanese Patent Application Laid-open No. Hei 8-40642 and Japanese Patent Application Laid-open No. Hei 9-156827 are representative. When welding work, the welding wire is consumed, and at the same time, it can naturally descend on the inner wall of the storage container, and it is equipped with a cushioning wing made of soft material for welding between the inner wall of the storage container and the buffer wing attached to the outer side of the annular member. Allow the wire to come out. This somewhat prevented the subsequent welding wire to be pulled out, but the problem that the welding wire is caught by the buffer wing to increase the withdrawal resistance and the problem that the annular member is drawn together with the welding wire.

Therefore, Japanese Patent Laid-Open No. 9-156827 attempts to solve this problem by supplementing the buffer wing because of the above problem, but it is not a fundamental solution.

In addition, other conventional entanglement preventing apparatuses are Korean Utility Model Publication No. 92-16429, 92-21073, and Korea Utility Model Publication No. 95-483.

In Korean Utility Model Publication No. 92-16429, an annular member is placed on the upper side of the welding wire and another small annular member is placed in the hole of the annular member to solve the problems of the inner drawing apparatus and the outer drawing apparatus. A wire was drawn out between the annular member and the small annular member. However, the problem that the subsequent welding wire is drawn out has not been solved, and the same problem as in Japanese Patent Laid-Open No. 8-40642 has occurred.

In addition, although the Korean Utility Model Publication No. 92-21073 used an annular member having a locking jaw, it was also difficult to prevent entanglement by filtering subsequent welding wires.

In addition, in order to prevent entanglement by filtering subsequent welding wires, Korean Utility Model Publication No. 95-483 puts a small annular member in the center hole of the welding wire stack and has a buffer blade inside the annular member to provide a small annular member. And the welding wire is drawn out between the annular member provided with a buffer wing. By the way, the buffer wing was somewhat effective in the function of filtering the subsequent welding wire, but the problem of pulling out the subsequent welding wire as the welding wire is pulled out was not solved and entanglement could not be prevented. In addition, there is a problem that the welding wire springs up due to an empty space between the buffer wing and the laminated surface of the welding wire.

Therefore, the present invention is to solve the problems of the prior art as described above, and provided with a means for mutual control so that subsequent welding wires are not drawn out or jumped up and tangled with each other to solve these problems, thereby providing convenience in welding operation. It is an object of the present invention to provide a welding wire tangle preventing device that is improved to enhance and improve work efficiency.

In order to achieve the above object, the present invention provides a large-capacity structure in which welding wires are stacked and stored therein in an eccentric continuous loop, and the welding wire laminates are stored in a vertically erect tubular shape. In the device which prevents entanglement of a welding wire, when a welding wire is pulled out from a container,

A ring member is provided on the upper laminated surface of the tubular laminate, and the ring member is formed of an outer material having an outer diameter smaller than the inner diameter of the large capacity container, and an inner material having an outer diameter smaller than the inner diameter of the outer material in the outer material. The ash has a plurality of combs extending from the inner diameter toward the inner material, the inner material has a plurality of combs extending from the outer diameter to the outer material, and a welding wire is drawn between the outer material and the inner material. By providing a wire tangle preventing device.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

In the welding wire entanglement preventing device of the present invention, the welding wire 110 is stacked and received while forming an eccentric in a spiral continuous loop, and the welding wire laminate 111 has a tubular shape standing vertically. When the welding wire is drawn out from the large-capacity container 100 to be stored, the welding wire 110 is prevented from tangling.

The welding wire entanglement preventing device of the present invention is a means for mutual control so that the welding wires 110 are not entangled with each other, and the ring member 11 is provided on the upper laminated surface of the tubular laminate 111, and the ring member 11 consists of an outer material 11a having an outer diameter smaller than the inner diameter of the large-capacity container 100, and an inner material 11b having an outer diameter smaller than the inner diameter of the outer material 11a in the outer material 11a. The outer member 11a has a plurality of comb teeth 12a extending from the inner diameter part to the inner member 11b, and the inner member 11b has a plurality of comb teeth 12b facing the outer member 11a from the outer diameter part. ) Is extended, and the welding wire 110 is naturally drawn out between the outer material 11a and the inner material 11b.

The plurality of comb teeth 12a and 12b provided on the ring member 11 are eccentrically welded in a spiral continuous loop when the welding wire 110 is drawn out between the inner and outer materials. While the wire 110 is easily drawn out even by a small drawing power, the comb teeth 12a and 12b are pushed out to the withdrawal direction of the welding wire 110 while being gradually released in a loop state. Only one strand of welding wire 110 is to be pulled out.

At this time, since the welding wire 110 gradually releases the loop from the stacked position, the closed end drawn out by the output power is eliminated. That is, the plurality of comb teeth 12a and 12b are elastically recovered so that the subsequent welding wires do not spring up, and are restored to their original positions, thereby controlling the subsequent jumping of the welding wires 110.

The plurality of comb teeth 12a and 12b is preferably a soft and elastic material that can be restored while being easily bent by the output of the welding wire 110.

In addition, the welding wire 110 eccentric in a spiral continuous loop during the lamination and storage of the welding wire 110, or during transportation and handling, the laminated upper loop (Loop) is a lower loop (Loop) A case is inserted into the bottom, and the welding wire 110 drawn out is pulled out into two or three strands and eventually springs out or becomes tangled.

However, in the welding wire tangling device according to the present invention, the ring member 11 is composed of an outer member 11a and an inner member 11b, and the outer member 11a is moved from the inner diameter portion to the inner member 11b. A plurality of comb teeth 12a are extended, and the inner material 11b has a plurality of comb teeth 12b extending from the outer diameter portion to the outer material 11a, so that the stacked upper loops have a lower loop. The comb teeth 12a and 12b are controlled to prevent the two or three strands of the welding wire 110 from being pulled out even when the case is inserted into the bottom, and the two or three strands of the welding wire ( Even if 110 is pulled out, a plurality of comb teeth 12a and 12b control the springing or tangling of the welding wire 110.

The ring member 11 has a plurality of comb teeth 12a extending from the inner diameter of the outer member 11a toward the inner member 11b, and the outer member 11b from the outer diameter portion of the inner member 11b. Since the welding wire 110 is pulled out by a plurality of comb teeth 12b and causes a small flow to the left and right, the welding wire 110 is consumed and descends naturally by its own weight.

In addition, the plurality of comb teeth (12a) (12b) is the length of the comb 12a of the outer material (11a) is equal to or shorter than the length of the comb (12b) of the inner material (11b), each of the outer material (11a) or inner The length of the comb teeth 12a and 12b of the member 11b preferably coincides with the interval between the inner diameter of the outer member 11a and the outer diameter of the inner member 11b or is shorter.

Since the welding wire 110 is eccentrically laminated in a continuous spiral loop, the length of the comb teeth 12a of the outer material 11a is greater than the length of the comb teeth 12b of the inner material 11b. If long, when the welding wire 110 is drawn out, there is a fear that the welding wire 110 is pulled out. More preferably, the length of the comb teeth 12a of the outer member 11a is shorter than the length of the comb teeth 12b of the inner member 11b.

Further, when the length of each comb 12a, 12b of the outer member 11a and the inner member 11b is longer than the interval between the inner diameter of the outer member 11a and the outer diameter of the inner member 11b, the welding wire ( When the 110 is drawn out, the withdrawal resistance increases due to the comb teeth 12a and 12b of the outer material 11a and the inner material 11b. In severe cases, the outer material 11a and the inner material 11b may be pulled up by the drawn welding wire 110. Therefore, in order to reduce the withdrawal resistance, the length of the comb teeth 12a and 12b of the outer member 11a and the inner member 11b coincides with the interval between the inner diameter of the outer member 11a and the outer diameter of the inner member 11b. It is preferable that the length is shorter.

In addition, the plurality of comb teeth 12a and 12b is preferably a comb 12a of the outer material (11a) and the comb 12b of the inner material (11b) intersected with each other. This is because the welding wire from which the comb teeth 12a of the outer member 11a and the comb teeth 12b of the inner member 11b can be mutually controlled due to such a structure.

The plurality of comb teeth 12a and 12b preferably form an acute angle between the outer member 11a and the inner member 11b. This is because a plurality of comb teeth 12a and 12b are easily bent in the drawing advance direction when the welding wire 110 is drawn out, and the drawing and feeding resistance can be reduced.

On the other hand, the welding wire 110 can be wound in the left or right side in the container 100, the present invention is suitable for all these structures. That is, according to the present invention, when the ring member 11 is turned upside down according to the left or right direction of the welding wire 110, the drawing and feeding resistance of the welding wire 110 may be reduced regardless of the winding direction of the welding wire 110. It can be reduced.

In addition, the plurality of comb teeth (12a, 12b) may be used as a plate-shaped strip or a needle-like brush (brush). The plurality of comb teeth 12a, which are in the form of bands, can be easily bent or restored, which is advantageous for controlling subsequent welding wires.

Moreover, it is more effective if it forms an acute angle with the upper laminated surface of the wire laminated body 111 for welding. That is, when the welding wire 110 is drawn out, the plurality of comb teeth 12a and 12b are easily bent in the drawing advance direction, and the drawing and feeding resistance can be reduced, and the welding wire stack 111 The upper laminated surface of the top surface) can be applied to the outer material (11a) and the inner material (11b), and a plurality of plate-shaped comb teeth 12a, 12b connected to each of them to apply a load of the welding wire (110) Of course, it is possible to add a pressing device (not shown) so that the stack 111 is not disturbed and tangled during transportation and handling.

In addition, a plurality of comb teeth 12a 'and 12b' having a needle-like brush shape may be easily bent or restored, and the drawing feeling is very soft, thereby reducing the drawing and feeding resistance to a minimum. Like an elongated tentacle, it works effectively to control subsequent welding wires.

In addition, the outer material 11a, the inner material 11b, and the plurality of comb teeth 12a, 12b, 12a 'and 12b' are effective as long as they are integrally injection molded. Such a unitary structure can be easily manufactured in large quantities, and a plurality of comb teeth 12a, 12b, and 12a 'and 12b' must be easily bent and elastically restored, and broken and dismantled in use. Since the durability to be satisfied, it is preferable that the injection molded integrally by selecting a material such as synthetic resin.

In the case of long-term storage or use, moisture absorption or deterioration should be small, and if there is a problem of preventing scratches or foreign matter attached to the surface of the welding wire 110, it is difficult.

More preferably, the ring member 11 is very effective if it is assembled from two or more parts of the same shape. If injection is performed in the state of one ring member 11, a problem arises that the injection mold must be very large. However, if it is assembled with two or more parts of the same shape, it can be dismantled after use and is easy to dispose. Storage space can also be used effectively.

6 shows a divided structure of the ring member as described above.

As shown in FIG. 6 a), in order to assemble the ring member 11 into two or more parts of the same shape, the convex portion 120 and the concave portion 130 may be provided at both ends. . That is, in use, when the convex portion 120 of one end portion is sequentially inserted into the concave portion 130 of the other end portion by a press-fit method, one round outer member 11a or inner member 11b can be formed. One ring member 11 may be configured by using the outer member 11a and the inner member 11b assembled as described above.

On the other hand, since such a split ring member 11 may be difficult to use because it is naturally disassembled during use, the convex portion 120 as shown in Figure 6b), c), d) in view of the advantage ) And the concave portion 130 can be provided with a small groove 131 and the projection 121 as a locking means.

The structure of the locking means is easy to fasten and dismantle the outer member (11a) and the inner member (11b), because it prevents spontaneous dismantling in use, it is provided with a very efficient wire tangling prevention device for welding.

That is, as shown in Figure 6b), a plurality of grooves 131 is formed on the upper and lower surfaces of the convex portion 120, the incision groove 132 is formed in the center portion, the concave portion to match the groove 131 The inner surface of the 130 is provided with projections 121, respectively, to combine them.

And, as shown in Figure 6c, a plurality of triangular fitting protrusions 121 are formed on the upper and lower surfaces of the convex portion 120, the incision groove 132 is formed in the center portion, so as to match the protrusion 121. Inner surfaces of the recess 130 are provided with grooves 131, respectively, to couple them. In this case, the triangular fitting protrusion 121 has an advantage that the outer surface is easily inserted into the recess 130 by forming an inclined surface.

In addition, as shown in FIG. 6d), a plurality of grooves 131 are formed on both side surfaces of the convex portion 120, respectively, and protrusions are formed on the inner surface of the recess 130 so as to correspond to the grooves 131, respectively. 121) to combine them. In this case, the recess 130 is formed so that the upper and lower surfaces of the outer member 11a or the inner member 11b pass through each other, and the ribs 135a and 135b forming the recess 130 face each other. It is to ensure that the coupling elastic force is formed between them.

In addition, the welding wire tangling device of the present invention is not provided with the inner tube 140, or even if the laminated body 111 of the welding wire storage container 100 is provided with the inner tube 140 can be applied to both. Of course it can.

As described above, the present invention is provided with a ring member 11 as a means for mutual control so that the welding wires are not entangled with each other, and further enhances convenience in welding operation by preventing subsequent wires from being entangled or raised. As a result, useful effects improved to improve work efficiency are obtained.
