Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for smoothly pulling out the welding wire from a welding wire storage container (commonly known as a pale bag) when the welding wire is taken out by the inner drawing method. The present invention relates to a welding wire storage mechanism, and particularly relates to a welding wire storage mechanism for smoothly taking out the stored tip wire (the tip at the beginning of winding and the rearmost end when pulled out).

[Prior Art] FIG. 2 is a partially cutaway perspective view showing an example of the structure of a pail bag used in a method for drawing out welding wire. Welding wires 3 wound into a ring shape are stacked and housed in the pail pack 2, and the lead-out end 3a of the wire is taken out from the upper side of the welding wire 3, and the storage tip wire 3c present at the bottom is shown in the figure. The winding wire is guided upwardly along the outer circumferential surface of the pail pack as shown in FIG. That is, the storage leading edge 3b passes through the through hole 6 of the presser plate 1, through the lower surface of the presser plate 1, and through the gap 7 between the inner wall surface of the pale pack and the outer circumferential surface of the wrapped welding wire 3 to form the winding start tip portion 3c, It continues to the welding wire located at the bottom of the pail pack 2. A holding plate 1 is provided on the upper surface of the winding wire 3 to prevent the wire from jumping up.
are provided, and through holes 9 are provided at four locations around the periphery of the presser plate 1. A string 8 having a length extending from the string fixing device 10a on the upper part of the pale pack to the string fixing device 10b on the lower part is arranged, and the middle part of the string 8 is passed through the through hole 9 of the presser plate 1 and stretched in the vertical direction. The welding wire is prevented from moving over the presser plate 11. As the holding plate 1 gradually descends as the welding wire is consumed, the string 8 slides up and down the through hole 9, so the string 8 does not prevent the holding plate 1 from descending.

[Problems to be Solved by the Invention] The wire 3 in the pail pack shown in FIG. 2 gradually decreases in height as the wire is consumed. FIGS. 3a and 3b are explanatory diagrams showing this situation. As the amount of the wound wire 3 decreases, the presser plate 1 descends and constantly presses down the upper surface of the wound wire 3 while continuing to prevent the wire from jumping up. However, the pressing force of the presser plate 1 does not reach the winding start tip 3c located at 7 between the inner wall of the pail pack 2 and the outer peripheral surface of the winding wire 3, and as shown in FIG. It jumps up. When the wire is further drawn out and only the final winding is left, the tip 3c springs up even more violently, as shown in Fig. 3c.
The situation will be as shown in . That is, since the string 8 is arranged at several places around the periphery of the presser plate 1, the wire winding start tip 3c does not cross over the center of the presser plate 1 and become entangled with the presser plate 1. At the time when the wire winding start tip 3c starts to be pulled out, the twist in the direction around the wire axis that has been applied around the final winding is applied to the wire winding start tip 3c, causing a twisted wire as shown in 3c''. Once the wire ring 3c'' is formed, the wire ring 3c'' will be gradually narrowed down as the wire is drawn out, and the wire will kink at the outlet.
As a result, it may become impossible to feed the wire, or it may cause problems such as the wire being cut.

Therefore, the inventors of the present invention have accumulated various ideas for the purpose of providing a storage mechanism that allows the tip of the winding wire to be pulled out smoothly, thereby allowing the wire to be smoothly connected to the next pack. , we have completed the present invention.

[Means for Solving the Problems] The present invention, which has achieved the above object, has three or more weight members disposed in a distributed manner on the upper part of the winding wire assembly so as to be freely descendable. Each upper end of the member is passed through the through hole of each weight member from the upper end fixing portion distributed in the circumferential direction of the storage container, and further reaches the bottom of the storage container via the outer peripheral surface of the wrapped wire layer. , the gist is that the lower end of the string member is fixed to the bottom.

[Function] A plurality of strings (three or more) extending from the top to the bottom of the pale pack are arranged at approximately equal intervals in the circumferential direction, and the middle portion of the strings is slidable with a weight member placed at approximately equal intervals in the circumferential direction. connected to. By disposing the weight member on the upper surface of the holding plate, the string member prevents the wire from jumping out in the lateral direction, and prevents the welding wire winding start end from springing upward. do. Since the weight member is configured to be able to move in the horizontal direction without being fixed to the holding plate, the holding plate follows the movement of the wire drawing end as the wound wire is drawn out. It can rotate and move, and even when the welding wire has reached the final winding turn, the wire can be pulled out while being sandwiched between the holding plate and the bottom of the pail pack, and the starting end of the wire can be pulled out through the holding plate through-hole. It is also possible to smoothly escape upward from the point. As a result, the escape of the wire tip is ensured, and the wire tip can be pulled out smoothly without kinking.

[Embodiment] FIG. 1 is a partially cutaway perspective view showing a typical embodiment of the present invention. The arrangement of the winding wire 3, presser plate 1, etc. is similar to the conventional example shown in FIG. The characteristic structure of this embodiment is that the same number of weights 11 as the strings 8 are placed on the upper part of the presser plate 1, and the strings 8 are connected to the weights 11 from the upper string fixing device 10a (fixed to the upper part of the pail pack 2). It passes through the through hole 11a of No. 11, reaches the outer peripheral edge from the upper surface of the presser plate 1, and is connected to the lower string fixing device 10b (fixed to the bottom of the pail pack 2). The string 8 that has reached the outer periphery of the presser plate 1 is attached to the pale pack 2.
The winding wire 3 is passed through the gap 7 between the inner wall and the outer circumferential surface of the winding wire 3, and is passed around a string fixture 10b provided at the bottom of the pail pack.

FIG. 4a shows a state in which the final one-turn wire remains after the pull-out end 3a is taken out, and the winding start tip 3c of the wire is regulated by strings 8a and 8b.
It protrudes above the presser plate 1 from between the inner wall surface of the pail pack 2 and the outer peripheral edge of the presser plate 1. However, the movement of the winding start tip 3c across the center of the presser plate 1 is restricted by the strings 8a and 8b, and as the wire winding start tip 3c is pulled out, the wire winding start tip 3c is moved one after another. It will be drawn into the lower part of the presser plate 1. The state in which the pull-out end 3a is further taken out is shown in the fourth figure.
Shown in Figure b. When the pull-out end 3a is unwound in the direction opposite to the direction in which it was rolled and stored (in the direction of arrow A), the force of the friction between the pull-out end 3a and the through hole 6 of the presser plate 1 causes the presser plate 1 to also rotate in the direction of arrow A. However, since presser plate 1 and weight 11 are not fixed, presser plate 1
can freely rotate horizontally. Therefore, the final winding of the wire is pulled out while being securely held by the holding plate 1. In addition, since the presser plate 1 and the strings 8 are not fixed, even when the presser plate rotates, the strings 8 are not dragged in the horizontal direction, and the plurality of strings 8 continue to maintain a constant interval. Therefore, the winding start tip 3c is gradually drawn into the lower part of the holding plate and smoothly taken out without increasing its length excessively. Therefore, under the influence of the twist of the final wire, the winding start tip 3c
kinks no longer occur. In addition, even when a large amount of wrapped wire 3 remains in the drawer, a similar effect of preventing the wire from springing up is exerted between the lower surface of the holding plate 1 and the upper surface of the wrapped wire 3, preventing the wires from getting tangled with each other and between the wire and the holding plate. No entanglements will occur.

The shape of the weight 11 is not limited to the illustrated example,
It may have any shape as long as it can slide freely on the string 8 through which the string 8 is inserted and is placed non-fixed on the presser plate 1. Further, the weight 11 may be one in which two, three, etc. string members can be inserted into one.

[Effects of the Invention] According to the present invention, it is possible to prevent wire entanglement and entanglement between the wire and the presser plate at the tip end of the wire winding start and the upper surface of the laminated wire, and the wire can be drawn out smoothly.
