Abstract

PURPOSE:To smoothly pull out a winding starting top edge part by placing weight members in dispersion on the upper part of a wound wire layer and allowing a string member fixed at the upper edge of an accommodation container to pass through a through hole of each weight member and to be fixed onto the bottom surface of the accommodation container through the outer peripheral surface of the wound wire layer. CONSTITUTION:The weights 11 in the equal number to that of strings 8 are placed on the upper part of a pressing plate 1, and the string 8 is introduced onto the outer peripheral edge from the upper surface of the pressing plate 1, pressing through the through hole 11a of the weight 11 from an upper part string fixing tool 10a, and connected with a lower part string fixing tool 10b. In the state where a wire for the last one turn is left, the winding starting top edge part 3c is regulated by the strings 8a and 8b, and projects over the pressing plate 1 from between the inner wall surface of a bail pack 2 and the outer peripheral edge of the pressing plate 1. The shift in which the winding starting top edge part 3c rides over the center part of the pressing plate 1 is regulated by the strings 8a and 8b. When the pulling-out edge 3a is further taken out and rewound in the direction of arrow A, the final winding of the wire is pulled out, surely held by the pressing plate 1.

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 pailback) when the welding wire is taken out by an inner drawing method. The present invention relates to a welding wire storage mechanism for use in storage, and particularly 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 drawn out).

[Prior Art] Figure 2 is a partially cutaway perspective view showing an example of the structure of a pailback used in a method for drawing out welding wire. Inside the bail pack 2, welding wires 3 wound in a wire ring shape are stored in a stacked manner, and the lead-out end 3a of the wire is taken out from the upper side of the welding wire 3. ) is guided above the pail bag along the outer peripheral surface of the wound wire as shown in the figure, and the leading edge 3b is held by a holder 4 (for example, adhesive tape) on the upper inner surface of the pail pack. That is, the storage leading edge 3b passes through the through hole 6 of the presser plate 1, passes through the lower surface of the presser plate 1, and passes through the gap 7 between the inner wall surface of the pailback and the outer peripheral surface of the winding welding wire 3 to form the winding start tip portion 3c. , continues to the welding wire located on the bottom surface of the pailback 2.

A presser plate 1 is provided on the upper surface of the winding wire 3 to prevent the wire from jumping up, and through holes 9 are provided at four locations on the periphery of the presser plate 1. The string 8 has a length from the string fixing device 10a at the top of the pale back to the string fixing device iob at the bottom.
is arranged, and the middle part of the string 8 is inserted into the through hole 9 of the presser plate 1.
This prevents the welding wire from moving over the holding plate 11. Note that 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 that the string 8 lowers the holding plate 1.
There is nothing that can prevent the decline.

[Problems to be Solved by the Invention] The bail pack wire 3 shown in FIG. 2 gradually decreases in height as the wire is consumed. Figure 3 (
a). (b) is an explanatory diagram showing the situation. As the amount of the wound wire 3 decreases, the holding 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 disposed in the gap 7 between the inner wall of the pail bag 2 and the outer peripheral surface of the winding wire 3, and as shown in FIG. 3(b), the presser plate 1
It springs upwards. When the wire was drawn out further and only the last winding was left, Chiro 3
The jump at point c becomes the most severe, resulting in the state shown in Figure 3 (C). 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
However, at the time when the tip end 3C of the wire winding starts to be pulled out, the direction around the wire axis given around the final winding is Twisting begins at the tip of the wire winding 3C
When the wire ring 30'' is formed, the wire ring 30'' is gradually narrowed as the wire is drawn out, and the wire is pulled out from the draw-out opening. As a result, the wire may become impossible to feed, or the wire may be cut.

Therefore, the inventors of the present invention have accumulated various ideas for the purpose of providing a storage mechanism that allows the winding start end of the winding wire to be pulled out smoothly, thereby allowing the wire to be smoothly connected to the next bag. The present invention has now been completed.

[Means for Solving the Problems] The present invention, which has achieved the above object, has three or more weight members distributively placed on the upper part of the wound wire layer so as to be freely descendable, and at least three wooden strings. Each upper end of the member is passed through the through hole of each weight member from the upper end fixing part 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 (3 or more) extending from the top to the bottom of the pail pack are arranged at approximately equal intervals in the circumferential direction, and the middle part of the strings is connected to a weight member placed at approximately equal intervals in the circumferential direction. Can be freely connected.

By disposing the weight member on the upper surface of the presser plate, the string member prevents the wire from jumping out in the lateral direction, and the tip of the welding wire winding start springs upward. to prevent 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 bail pack. 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 bag 2). It passes through the through hole 11a of the weight 11, reaches the outer peripheral edge from the upper surface of the presser plate 1, and is connected to the lower string fixing device iob (fixed to the bottom of the pail pack 2). The string 8 that has reached the outer peripheral edge of the presser plate 1 passes through the gap 7 between the inner wall of the pail bag 2 and the outer peripheral surface of the winding wire 3 and is wrapped around a string fixing device tab provided at the bottom of the pail pack.

FIG. 4(a) 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 3 of the wire remains.
C is regulated by strings 8a and 8b, and protrudes above the presser plate 1 from between the inner wall surface of the pail bag 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 pull-out end 3a is pulled out, the wire winding start tip 3C moves one after another from the presser plate 1. It will be drawn to the bottom of 1. Figure 4(b) shows the state in which the pull-out end 3a is further removed. When the pull-out end 3a is unwound in the direction opposite to the direction in which it was rolled and stored (in the eight directions of arrows), the force of friction between the pull-out end 3a and the through hole 6 of the presser plate 1 causes the presser plate 1 to rotate in the direction of the arrow A. However, since the presser plate 1 and the weight 11 are not fixed, the presser plate 1 can freely rotate in the horizontal direction.Therefore, the final winding of the wire is reliably held by the presser plate 1 and pulled out. In addition, since the presser plate 1 and the strings 8 are not fixed, even if 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. 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 etc. no longer occur. Also, wrapping wire 3
Even during the drawer when a large amount of wire remains, the same spring-up prevention effect is exerted between the lower surface of the presser plate 1 and the upper surface of the wrapped wire 3, and tangles between the wires and entanglement between the wire and the presser plate do not occur. .

The shape of the weight 11 is not limited to the one shown in the figure, but can be any shape as long as it can be inserted through the string 8 and slidably move on the string 8, and can be placed non-fixed on the presser plate 1. It may be a shape. Further, the weight 11 may be a combination of two, three, etc. string members that 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.
