Description

  The present invention relates to a method for storing a welding wire in which a welding wire is fed from a bobbin set in a wire feeding machine, and the fed welding wire is spirally dropped from a conical flyer into a cylindrical container to be distributed and stored in a stacked manner.

  As a wire storage device that implements a method for storing welding wires in which a welding wire fed from a bobbin set in a wire feeding machine is spirally dropped into a wire storage container and dispersedly stored in a laminated form, for example, Patent Document 1 described later is used. Those having the structure are known. Hereinafter, the wire storage device according to this conventional example will be described with reference to the accompanying drawings. FIG. 5 is a partial cross-sectional side view of a wire (wire) storage device according to a conventional example for carrying out a welding wire storage method, and FIG. 6 is a perspective view of a wire storage container.

  The wire storage device B according to this conventional example uses a wire for welding (hereinafter referred to as a welding wire) W having a diameter of about 0.9 to 2.0 mm, which is supplied with a constant spiral diameter, to the wire storage container A. Regardless of the storage position in the section 51, the wire storage section 51 can be stored in a stable posture, and when the stored welding wire W is fed out from the wire storage section 51, it is fed at a desired feeding speed. It can be put out.

  More specifically, the wire storage container A that stores the welding wire W of the wire storage device B according to this conventional example is configured as described later. That is, this wire storage container A protrudes at a concentric position with a conical outer cylinder part 52 having a large upper end diameter and a bottom plate part 54 on the lower end side of the conical outer cylinder part 52, and has a truncated conical shape with a small upper end diameter. In addition, the inner cylindrical portion 53 includes an outer peripheral surface 53a having the same taper angle as the outer peripheral surface 52a of the outer cylindrical portion. A space between the inner peripheral surface 52 a of the conical outer cylinder portion 52 and the outer peripheral surface 53 a of the inner cylinder portion 53 is a wire storage portion 51 that stores the welding wire W.

  A wire storage device B that drops and welds welding wires W into the wire storage container A and supplies them in a spiral central axis X along the vertical direction while winding the welding wires W spirally. And the wire supply apparatus B1 accommodated in the wire storage part 51 of the said wire storage container A is provided. The wire supply device B1 includes a capstan 55 that pulls out the welding wire W at a predetermined constant speed, and a pressing roller 56 that presses the welding wire W wound around the capstan 55.

  The welding wire W drawn from the capstan 55 is connected to a cylindrical guide tube 58 with a canopy that is rotated about the helical center axis X via a rotating tube shaft 59 that is rotated by a drive motor M1. It is configured to be inserted into a spiral guide pipe 57 attached to the outer periphery and wound spirally with a constant spiral diameter. Reference numeral 60 shown in FIG. 5 is a bearing that supports the rotary cylinder shaft 59 so as to be rotatable about a vertical axis.

  Further, the wire storage device B according to this conventional example is configured so that the wire storage container A mounted on the inclined mounting base 63 of the lifting / lowering base 62 is connected to the bus 52V of the inner peripheral surface 52a of the outer cylindrical portion 52 in the vertical direction. Rotating means B2 for rotating the wire storage container A around the cylinder axis Y is provided. The rotating means B2 includes an elevating device B3 having a hydraulic cylinder 65 for elevating the elevating table 62.

  Therefore, according to the wire storage device B according to this conventional example, the inclined mounting base 63 on which the wire storage container A is placed is raised by the raising of the lifting base 62 until it reaches a predetermined height. Next, the cylindrical guide tube 58 is rotated by the drive motor M1, and the wire storage container A is rotated and lowered by the drive motor N2 of the rotation means B2. The wire is stored in the A wire storage 51. Thus, when the operation of storing the welding wire W in the wire storage portion 51 of the wire storage container A is completed, the rotation of the wire supply device B1 and the wire storage container A is stopped. Then, the welding wire W is cut in the vicinity of the outlet of the spiral guide pipe 57, and the elevating table 62 is lowered until the guide tube 58 comes out of the wire storage portion 51, and the wire storage container A in which the welding wire W has been stored is placed on an inclined surface. It is removed from the base 63.

  In addition, the upper surface position of the aggregate C of the welding wires W stored in the wire storage portion 51 of the wire storage container A is continuously detected by the magnetic sensor 67 provided outside the wire storage container A. . Based on the detection information of the magnetic sensor 67, the protruding member 61 attached to the guide cylinder 58 is rotated near the upper surface of the assembly C at the position of the vertical bus 52V on the outer peripheral surface 52a of the outer cylinder. Be controlled. That is, the guide cylinder 58 is lowered by the lowering speed control of the elevating device B3 so that the welding wire W supplied while being spirally wound falls from the vicinity of the upper surface of the integrated body C.

  According to the wire storage device according to the conventional example, the welding wire can be stored in the wire storage portion in a stable posture regardless of the storage position in the wire storage portion of the wire storage container, and the stored welding wire Since it can be drawn out at a desired feeding speed when it is fed out from the wire accommodating portion, it is considered extremely useful. However, the wire storage device according to this conventional example has problems to be solved as described later.

In the case of the wire storage device according to this conventional example, the welding wire is wound around a single type capstan (usually provided with a V-groove) by one rotation + 90 ° (450 °).
Then, the wound welding wire slides in the direction of the width of the capstan and in the direction of approaching each other in the hanging region, so that the welding wire fed from the capstan is twisted. Therefore, when the welding wire is stored in the wire container and when the welding wire is pulled out from the wire container, the welding wire may be tangled.

  The wire storage container includes a conical outer cylinder portion having a large diameter at the upper end, and an inner cylinder portion having a truncated cone shape having a small diameter at the upper end and having an outer peripheral surface having the same taper angle as the inner peripheral surface of the outer cylinder portion. And the configuration is complicated. Therefore, in addition to the high cost of the wire storage container, there is a problem that it is impossible to avoid a wasteful space when storing the wire storage container (product) storing the welding wire.

  Moreover, the wire storage container is mounted in an inclined state on a disk-shaped base plate having a circular protruding outer edge protruding above an inclined platform provided on the lifting platform. Accordingly, when removing the wire storage container after the welding wire storage is completed, it is necessary to lift it upward, and when lifting, the outer peripheral surface of the bottom of the wire storage container may come into contact with the inner peripheral surface of the protruding outer edge of the inclined platform. Therefore, there is a problem that it takes time to remove the wire storage container. Of course, the wire storage container can be easily removed by using a dedicated removal device that lifts the wire storage container in an oblique direction and lowers it vertically, but this is disadvantageous in terms of the initial cost of the equipment. This is not preferable because it causes problems.

  In addition, in the case of the wire storage device according to this conventional example, since the welding wire is simply spirally dropped into the wire storage container and dispersedly stored, the entire storage space of the wire storage container is not necessarily effective for storing the welding wire. It cannot be said that it is utilized, and there is a problem that the storage rate (filling rate) of the welding wire is not sufficient. Further, the vibration of the wire storage container when transported by a truck or the like may cause the welding wire to move in the wire storage container and become tangled when pulled out from the wire storage container, which may interfere with the welding operation. There were also problems to be solved.

  The present invention has been made in view of the above circumstances, and the means employed by the welding wire storage method according to claim 1 of the present invention in order to solve the above-described problem is that a welding wire fed from a bobbin is used as a dancer. It is introduced into a wire guide tip attached to the outer peripheral surface of a conical fryer rotating around a vertical axis through a roller device and a capstan, respectively, and guided downward, while the vertical axis is below the flyer. In a method for storing a welding wire that is spirally dropped and laminated in a cylindrical container that rotates around, a welding roller that is led from the dancer roller device is driven by a drive roller having a flat wrapping surface of the capstan. Each of which is hung on a roller and introduced into the wire guide tip of the fryer, and the lower end of the fryer is stacked in the cylindrical container. The welding wire is placed in the cylindrical shape while monitoring the close state of the welding wire close to the upper end of the welding wire and decentering the vertical rotation center of the flyer and the vertical rotation center of the cylindrical container from each other. It is characterized by being dropped into a container.

  The means adopted by the welding wire storage method according to claim 2 of the present invention is the welding wire storage method according to claim 1, wherein the lower end of the flyer and the upper end of the laminated welding wire in the cylindrical container are provided. The distance is detected by a proximity sensor, and the height position of the cylindrical container is controlled so that the distance falls within a predetermined range.

  The means employed by the welding wire storage method according to claim 3 of the present invention is the welding wire storage method according to any one of claims 1 and 2, wherein the cylindrical container is vibrated. However, the welding wire is laminated.

  According to a fourth aspect of the present invention, there is provided the welding wire storage method according to any one of the first to third aspects, wherein the welding wire is stored in the cylindrical container. The welding wire is laminated while striking the outer peripheral surface of the portion.

  The welding wire storage method according to claim 5 of the present invention employs the welding wire storage method according to any one of claims 1 to 4, wherein the welding wire is the cylindrical container. The cylindrical container is vibrated for a predetermined time after being housed therein.

  According to the method for storing a welding wire according to claim 1 of the present invention, the welding wire led out from the dancer roller device is hung on the flat hung surfaces of the drive roller and the driven roller of the capstan. Therefore, even if the welding wire that has passed through the follower roller of the capstan is hung at a position different from the welding wire that is derived from the dancer roller device of the drive roller, the welding wire that has passed through the follower roller will still have a width of the drive roller. The welding wire is not moved in the direction, and twisting is not applied to the welding wire. Therefore, when the welding wire is stored in the wire container and when the welding wire is pulled out from the wire container, the welding wire There is no fear of tangling.

  According to the welding wire storage method of the first aspect of the present invention, the welding wire fed from the double capstan and introduced into the wire guide tip of the flyer is rotated at the lower end of the flyer rotating about the vertical axis. From the vertical axis of the flyer, it is spirally stacked and stored in a cylindrical container that rotates about a vertical axis that is eccentric to the vertical axis. Therefore, the cylindrical container has a truncated cone shape and does not include an inner cylinder portion having an outer peripheral surface having the same taper angle as the inner peripheral surface of the outer cylinder portion, unlike the conventional wire storage container. Therefore, in addition to the low cost, it is possible to avoid the generation of a useless space when storing the cylindrical container storing the welding wire.

  According to the welding wire storage method of the first aspect of the present invention, the cylindrical container is configured to rotate about the vertical axis, and is mounted in an inclined state like the conventional wire storage container. It is not a configuration to be placed. Accordingly, there is no need to prepare a dedicated removal device for lifting the wire storage container obliquely upward and lowering it vertically, so that the initial cost of the equipment related to the welding wire storage device is more advantageous than in the case of the conventional example. Become.

  According to the welding wire storage method of the second aspect of the present invention, the cylindrical shape is such that the distance between the lower end of the flyer detected by the proximity sensor and the upper end portion of the laminated welding wire in the cylindrical container is within a predetermined range. The height position of the container is controlled. According to the welding wire storage method of the present invention, the cylindrical container is vibrated while the welding wires are stacked and stored. Furthermore, according to the method for storing a welding wire according to claim 4 of the present invention, the cylindrical container is hit while the welding wires are stacked and stored. Therefore, according to the method for storing the welding wire according to claims 2 to 4 of the present invention, the welding wire dropped and stacked in a spiral shape is closely stored in the cylindrical container. The rate (filling rate) is improved.

  According to the method for storing a welding wire according to claim 5 of the present invention, since the cylindrical container is vibrated for a predetermined time after the welding wire is stored, the welding wire moves to a stable position in the cylindrical container, and further It is kept in a state that does not move due to vibration. Accordingly, since the welding wire stored in the cylindrical container does not move due to vibration during transportation of the cylindrical container by a truck or the like, the welding wire is reliably prevented from being tangled when being pulled out from the cylindrical container. be able to.

  The wire feeding machine 2 includes a drive motor (not shown) that rotates a bobbin 2a that is detachably set in order to feed the welding wire W. The dancer roller device 3 includes a fixed side roller 3a around which a welding wire W fed out from the bobbin 2a is wound, and a moving side roller 3b. The moving side roller 3b functions to hold the tension of the welding wire W at a predetermined value by moving up and down at a position below the fixed side roller 3a to absorb the elongation of the welding wire W and the like. The straightening roller device 4 includes a plurality of horizontal roller groups (not shown) that roll up and down a welding wire W that rotates by rotating around a horizontal axis that faces up and down in a zigzag manner, and faces the zigzag in the left and right direction. A plurality of vertical roller groups (not shown) are provided in rolling contact with the left and right of the welding wire W that rotates around the vertical axis.

  By the way, in the case of the welding wire storage apparatus 1 which concerns on embodiment of this invention, the correction roller apparatus 4 is provided in the back process side of the dancer roller apparatus 3 as mentioned above. However, since there is also a welding wire storage device in which the correction roller device 4 is not provided on the downstream side of the dancer roller device 3, the invention is not limited to the form of the welding wire storage device 1 provided with the correction roller device 4. .

  The double capstan 5 has an upper drive roller 5a around which a welding wire W straightened by the straightening roller device 4 is wound and driven to rotate around a horizontal axis by a drive motor (not shown), and the drive roller 5a, and a driven roller 5b which is disposed obliquely to the left in FIG. 1 and is supported by a horizontal shaft so as to be freely rotatable. As shown in FIG. 2, flanges 5c are formed on both sides of the drive roller 5a and the driven roller 5b in the width direction, and a winding surface 5d of the welding wire W between the flanges 5c and 5c is It is formed flat.

The welding wire W straightened by the horizontal roller group and the vertical roller group of the straightening roller device 4 is first hung on the upper side of the driving roller 5a, and the direction is changed diagonally to the left and hung on the lower side of the driven roller 5b. It is done. The welding wire W hung on the lower side of the driven roller 5b is direction-changed obliquely upward to the right by the driven roller 5b and hung on the upper side of the driving roller 5a. Then, the welding wire W hung on the upper side of the drive roller 5a is changed in the downward direction and is supplied to the wire storage device 6 described later.
In FIG. 1, the roller formed by rolling contact with the right side of the driving roller 5a is a pressing roller 5e that presses the welding wire W wound around the driving roller 5a.

The wire storage machine 6 includes a frame-like frame 6a having an upper horizontal member and a plurality of support members that support the upper horizontal member. This upper cross member of the frame-shaped frame 6a, flyer 6b conical rotated to the vertical axis L ₁ about by a drive motor (not shown) is supported. A short cylindrical wire guide tip 6c having a wire introduction hole into which the welding wire W is introduced is provided at a predetermined interval on the outer peripheral surface of the flyer 6b, and is lowered by a drive roller 5a of the double capstan 5. The welding wire W whose direction has been changed in the lateral direction is guided in a spiral manner so that the spiral diameter gradually increases as it goes downward.

Further, the wire housing unit 6 is provided with a rotary table 6d for rotating the cylindrical container 8 to the vertical axis L ₂ about an eccentric vertical axis L ₁ of the flyer 6b. A plurality of rotating rods 6e are arranged in parallel on the rotating table 6d, and the cylindrical container 8 can be fixed and released on these rotating rods 6e by detachable container fixing means (not shown). It is configured to be loaded on.

The rotary table 6d is supported by a vertical rotary shaft provided on a lifting platform 6f that is vibrated by a vibrating means (not shown). The lifting table 6f includes a table drive motor 6g, A speed reducer 6h for reducing the rotational speed of the table drive motor 6g to a predetermined rotational speed and transmitting it to the rotating shaft is provided. The lifting platform 6f is configured to be lifted and lowered via a wire rope (not shown) connected to a telescopic rod of a hydraulic cylinder (not shown). The expression “vertical” between the vertical axis L ₁ and the vertical axis L ₂ means “vertical”, and so on.

  Further, a rod projecting downward is provided on the lower side of the upper horizontal member of the frame 6a, and an upper end portion of the laminated welding wire spirally accommodated in the cylindrical container 8 is provided at the tip of the rod. A proximity sensor 6i that detects the distance is provided. The height of the cylindrical container 8 is controlled so that the distance detected by the proximity sensor 6i is within a predetermined range. That is, as the storage amount of the welding wire W increases as the storage operation continues, the lifting platform 6f is controlled to be lowered.

  Further, the container hitting device hits the outer peripheral surface of the welding wire storage portion of the cylindrical container 8 at a position below the upper horizontal member of the frame 6a and shifted from the rod supporting the proximity sensor 6i. 6j is provided. The container hitting device 6j includes a swing rod in which a base end side is pivotally attached to a bracket provided on the lower side of the upper horizontal member via a shaft, and rod operating means such as an air cylinder for swinging the swing rod. The striking member is provided on the lower end side of the swing rod and for striking the outer peripheral surface of the cylindrical container 8.

  Note that the distance detected by the proximity sensor 6i is preferably kept at about 5 to 10 cm, for example. That is, when the distance is less than 5 cm, the welding wire W may interfere with the upper end of the stacked welding wire that has been housed when dropping into the cylindrical container 8, which may hinder the dropping of the welding wire W. Because there is. Further, when the distance exceeds 10 cm, the welding wire W cannot be dropped into a normal spiral shape, and the welding wire W may be tangled.

  When the operation of storing the welding wire W in the cylindrical container 8 on the rotary table 6d is completed, it is necessary to remove the container fixing means and move the cylindrical container 8 from the rotary table 6d to the roller way 7. However, since the cylindrical container 8 is located inside the frame-shaped frame 6a in a state where the welding operation of the welding wire W has been completed, for example, an operator cannot enter the frame, so When moving out of the frame 6a, a container pushing device 9 as shown in FIG. 3 is used.

  The container pushing device 9 is provided on the lifting platform 6f and includes an arm 9a that pushes the cylindrical container 8 and moves it to the roller way side. The base end side of the arm 9a is fixed to the upper surface of the reciprocating table 9b by mechanical fastening means such as bolts. The reciprocating table 9b is guided by a pair of guide rods 9e, and is configured to reciprocate by a screw rod 9d rotated by a drive motor 9c.

  The cylindrical container 8 containing the welding wire, which has been moved onto the roller way 7 by the container extruding device 9 having the above-described configuration, is moved to the product accumulation site via the roller way 7. In the middle of this, a container vibration device (not shown) is provided, and the container vibration device vibrates for about 30 seconds, for example. The vibration time of the cylindrical container 8 of 30 seconds by the container vibration device is determined from experience, and is not particularly limited to 30 seconds.

Hereinafter, the operation mode and effects of the welding wire storage device 1 having the above-described configuration will be described.
First, the empty cylindrical container 8 is loaded on the rotary table 6d, and the cylindrical container 8 is fixed on the rotary table 6d by the container fixing means. When the lift 6f is raised and the distance between the flyer 6b and the bottom surface of the cylindrical container 8 reaches a preset value, the lift of the lift 6f is stopped and the welding wire storage device 1 The operation is started, and the welding wire W is fed out from the bobbin 2a that is detachably set on the wire feeding machine 2.

The welding wire W fed out from the bobbin 2a is introduced into the correction roller device 4 after the tension is adjusted by moving the moving roller 3b of the dancer roller device 3 toward and away from the fixed roller 3a. Welding wire W that has been corrected by the correction roller device 4, the driving roller 5a of the double capstan 5, a driven roller 5b, through the order of the driving roller 5a of the conical rotating in the vertical axis L ₁ about the wire housing unit 6 It is introduced into a plurality of wire guide chips 6c attached to the outer peripheral surface of the flyer 6b.

Then, the welding wire W introduced into the wire guide tip 6c is guided downward along the outer peripheral surface of the flyer 6b while drawing a spiral whose diameter gradually increases, and is vertically below the flyer 6b by the rotary table 6d. It is dropped into the cylindrical container 8 is rotated in the axis L ₂ about. Welding wire W that has been dropped into the cylindrical container 8, since the vertical axis L ₂ of the vertical axis L ₁ and the cylindrical container 8 fryer 6b is decentered, as shown in FIG. 4, the The cylindrical container 8 is stacked and stored in a spiral shape.

  While the welding wire W is being stored in the cylindrical container 8, the distance between the lower end of the flyer 6b and the upper end of the laminated welding wire in the cylindrical container 8 is detected by the proximity sensor 6i. . Then, a hydraulic cylinder (not shown) controlled by a control device (not shown) that receives a detection signal from the proximity sensor 6i so that the distance detected by the proximity sensor 6i falls within a predetermined range of 5 to 10 cm. ) Lowers the lifting platform 6f and controls the height position of the cylindrical container. Further, during the storing operation of the welding wire W, the cylindrical container 8 is continuously vibrated via the lifting platform 6f which is continuously vibrated by a vibrating means (not shown), and the cylindrical container 8 is The outer peripheral surface of the welding wire storage portion continues to be struck by the container hitting device 6j.

  When the storage of the welding wire W in the cylindrical container 8 is completed, the operation of the welding wire storage device 1 is stopped. Then, the welding wire W is cut in the vicinity of the outlet of the lowermost wire guide tip 6c, the elevating platform 6f is lowered until the flyer 6b comes out of the upper end of the cylindrical container 8, and the container fixing means is moved from the rotary table 6d. Removed. When the container fixing means is removed, the cylindrical container 8 is pushed out from the frame-shaped frame 6 a onto the roller way 7 by the arm 9 a of the container pushing device 9.

  The cylindrical container 8 containing the welding wire pushed out onto the roller way 7 by the arm 9a of the container pushing device 9 is conveyed to a container vibration device (not shown) provided in the middle of the roller way 7. Is done. The cylindrical container 8 conveyed to the container vibration device is vibrated for about 30 seconds by the container vibration device, and then again conveyed to the product accumulation place via the roller way 7. Then, after being closed at the product accumulation place, it is stored at the product accumulation place until it is shipped.

  According to the welding wire storage method of the present invention by the welding wire storage device 1 configured as described above, the following excellent effects can be obtained. That is, the welding wire W fed out from the bobbin 2a and led out from the dancer roller device 3 and corrected by the correction roller device 4 is, as described above, between the driving roller 5a of the double capstan 5 and the driven roller 5b. It is hung on the flat hung surface 5d.

  In this case, even if the welding wire W passed through the driven roller 5b is hung at a position different from the welding wire derived from the correction roller device 4 of the driving roller 5a, the welding wire W hung through the driven roller 5b is still connected to the driving roller 5a. Therefore, the welding wire W is not twisted. Therefore, there is no fear that the welding wire W will be tangled when the welding wire W is stored in the wire container 8 and when the welding wire W is pulled out from the wire container 8. On the other hand, the hung surface 5d of the driving roller 5a and the driven roller 5b of the double capstan 5 has a groove shape that is recessed toward the center, such as a V shape, and is not flat as in the present invention. In this case, there is a high possibility that the welding wire W is twisted. This is because there is a high possibility that the welding wire W hung through the driven roller 5b moves in the width direction of the driving roller 5a along the groove shape (toward the V-shaped dent of the hung surface 5d). is there.

Further, according to the welding-wire-storing method of the present invention, the welding wire W that has been introduced into the wire guide tip 6c of Repetitive issued by flyer 6b from the driving roller 5a of the double capstan 5 is rotated in the vertical axis L ₁ about from the lower end of the flyer 6b which are stacked in a spiral in a cylindrical container 8 rotates accommodated in the vertical axis L ₂ about eccentric to each other with the vertical axis L1 of the flyer 6b. Therefore, the cylindrical container 8 has a truncated cone shape and an inner cylinder portion having an outer peripheral surface having the same taper angle as the inner peripheral surface of the outer cylinder portion, like the wire storage container according to the conventional example. Since the configuration is simple, it is possible to avoid a wasteful space when storing the cylindrical container 8 storing the welding wire W in addition to being low-cost.

Further, according to the welding-wire-storing method of the present invention, the cylindrical container 8 is a configuration which is rotated to the vertical axis L ₂ about through the rotary table 6d, as a wire storage container according to the prior art, It is not the structure mounted in an inclined state on an inclined mounting base. Accordingly, since it is not necessary to prepare a dedicated removal device for lifting the wire storage container obliquely upward and lowering it vertically, the initial cost of the equipment relating to the welding wire storage device 1 is more than that of the conventional example. Become advantageous.

Further, according to the welding wire storage method of the present invention, the distance between the lower end of the flyer 6b detected by the proximity sensor 6i and the upper end of the laminated welding wire in the cylindrical container 8 is within a predetermined range of 5 to 10 cm. Thus, the height position of the cylindrical container 8 is controlled by the lowering of the lifting platform 6f.
Further, while the welding wire W is being stacked and stored, the cylindrical container 8 continues to be vibrated via the lifting platform 6f which is vibrated by the vibrating means, and the welding wire storage portion of the cylindrical container 8 by the container impact device 6j The outer peripheral surface of is kept being hit. Therefore, since the welding wires W dropped and stacked in a spiral shape are densely accommodated in the cylindrical container 8, the accommodation rate (filling rate) of the welding wires W is improved.

  Furthermore, according to the welding wire storage method of the present invention, the cylindrical container 8 is vibrated for a predetermined time (about 30 seconds) after the welding wire W is stored, so that the welding wire W is stabilized in the cylindrical container 8. It moves to a position and is kept stationary by further vibrations. Accordingly, since the welding wire W accommodated in the cylindrical container 8 does not move due to vibration during transportation of the cylindrical container 8 by a truck or the like, the welding wire W is entangled when pulled out from the cylindrical container 8. Can be reliably prevented.

  By the way, in the above welding wire storage apparatus 1, the case where the flyer 6b was formed in the cone shape was demonstrated. However, the technical idea of the present invention can be applied not only to such a flyer but also to a welding wire storage device according to a conventional example provided with a cylindrical guide tube (corresponding to a flyer).

  As described above, according to the present invention, there is no fear that the welding wire is tangled when the welding wire is accommodated in the wire accommodating container and when the welding wire is pulled out from the wire accommodating container. Further, since the configuration of the cylindrical container or the like is simple, in addition to being low in cost, it is possible to avoid the generation of a useless space when storing the cylindrical container storing the welding wire. Therefore, a step of unwinding a coiled hoop (band steel) and forming it into a U-shaped band steel, a step of filling the flux in the middle of molding the hoop, and further drawing a tubular forming wire filled with the flux It is suitable for a storage device and method for a welding wire manufactured by a highly efficient manufacturing line, such as a flux-cored welding wire manufactured by continuously performing a winding process on the same line.
