STORAGE METHOD FOR WELDING WIRE
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a welding-wire storage method for paying out a welding wire from a bobbin set in a wire dispenser and helically dropping the paid-out welding wire from a conical flyer into a cylindrical container so that the welding wire is stored in layers.
2. Description of the Related Art
For example, Japanese Unexamined Patent Application Publication No. 09-136767 discloses a wire storage apparatus that adopts a welding-wire storage method for helically dropping a welding wire, which is paid out of a bobbin set in a wire dispenser, into a wire storage container so that the welding wire is stored in layers. The wire storage apparatus of this related art will be described below with reference to the attached drawings. Fig. 5 is a partly sectional side view of the wire storage apparatus of the related art that carries out a welding-wire storage method, and Fig. 6 is a perspective view of a wire storage container.
A wire storage apparatus B of the related art allows a wire W for welding (hereinafter referred to as a welding wire), which has a diameter of about 0.9 to 2.0 mm and is supplied with a fixed helical diameter, to be stored in a stable posture in a wire storage portion 51 of a wire storage container A, regardless of the storage position in the wire storage portion 51. The wire storage apparatus B also allows the stored welding wire W to be paid out from the wire storage portion 51 at a desired speed.
More specifically, the wire storage container A for storing the welding wire W in the wire storage apparatus B of the related art has the following structure: The wire storage container A includes a conical outer cylindrical portion 52 having a large-diameter upper end, and an inner cylindrical portion 53 concentrically projecting from a bottom plate portion 54 at a lower end of the conical outer cylindrical portion 52. The inner cylindrical portion 53 is shaped like a truncated cone with a small-diameter upper end, and has an outer peripheral surface 53a with the same taper angle as that of an inner peripheral surface 52a of the outer cylindrical portion 52. The wire storage portion 51 for storing the welding wire W is defined between the inner peripheral surface 52a of the conical outer cylindrical portion 52 and the outer peripheral surface 53a of the inner cylindrical portion 53.
The wire storage apparatus B helically drops the welding wire W into the wire storage container A so as to store the welding wire W in layers. The wire storage apparatus B includes a wire supply device B1 for supplying the welding wire W along the helical center axis X serving as the vertical axis while helically winding the welding wire W so as to store the welding wire W in the wire storage portion 51 of the wire storage container A. The wire supply device B1 includes a capstan 55 for paying out the welding wire W at a predetermined fixed speed, and a pressing roller 56 for pressing the welding wire W wound on the capstan 55.
The welding wire W paid out from the capstan 55 is inserted into a helical guide pipe 57. The helical guide pipe 57 is attached to an outer periphery of a canopied guide cylinder 58 that is rotated on the helical center axis X via a rotary cylindrical shaft 59 rotated by a driving motor Ml. Further, the welding wire W is helically wound with a fixed helical diameter. In Fig. 5, a bearing 60 supports the rotary cylindrical shaft 59 rotatably on the vertical axis.
The wire storage apparatus B of the related art also includes a rotating means B2 that rotates the wire storage container A placed on an inclined table 63 of a lifting platform 62 on the cylinder axis Y of the wire storage container A in a manner such that a generator 52V of the inner peripheral surface 52a of the outer cylindrical portion 52 coincides with the vertical direction. The rotating means B2 includes a lifting device B3 having a hydraulic cylinder 65 for moving the lifting platform 62 up and down.
Thus, according to the wire storage apparatus B of the related art, the inclined table 63 on which the wire storage container A is placed is lifted to a predetermined height by upward movement of the lifting platform 62. Next, the guide cylinder 58 is rotated by the driving motor Ml, and the wire storage container A is rotated and moved down by a driving motor N2 of the rotating means B2, so that the welding wire W is inserted in the wire storage portion 51 of the wire storage container A. When this operation of inserting the welding wire W in the wire storage portion 51 is finished, rotations of the wire supply device B1 and the wire storage container A are stopped. Then, the welding wire W is cut near the exit of the helical guide pipe 57, the lifting platform 62 is moved down until the guide cylinder 58 moves out of the wire storage portion 51, and the wire storage container A in which the welding wire W has been inserted is detached from the inclined table 63.
The position of an upper surface of a stack C of welding wire W stored in the wire storage portion 51 of the wire storage container A is continuously detected by a magnetic sensor 67 provided outside the wire storage container A. On the basis of detection information from the magnetic sensor 67, control is exerted so a projecting member 61 provided in the guide cylinder 58 is rotated near the upper surface of the stack C at the vertical generator 52V of the inner peripheral surface 52a of the outer cylindrical portion 52. In other words, the guide cylinder 58 is lowered by the control of lowering speed of the lifting device B3 so that the welding wire W that is supplied while being helically wound falls from a position near the upper surface of the stack C.
According to the above-described wire storage apparatus of the related art, the welding wire can be stored in a stable posture in the wire storage portion of the wire storage container, regardless of the storage position in the wire storage portion. Moreover, since the stored welding wire can be paid out from the wire storage portion at a desired speed, availability seems high. However, the wire storage apparatus of the related art has the following problems to be solved.
In the wire storage apparatus of the related art, the welding wire is wound around a single capstan (normally, having a V-groove on the periphery) to form one and a quarter turns (450°).
Since the wound welding wire slips in the width direction of the capstan and in a direction to move the turns close to each other in a winding area, it is twisted when paid out from the capstan. Therefore, the welding wire is sometimes tangled when inserted in and paid out of the wire storage container.
Further, the structure of the wire storage container is complicated because the wire storage container includes the conical outer cylindrical portion having the large-diameter upper end and the inner cylindrical portion shaped like the truncated cone having the small-diameter upper end and provided with the outer peripheral surface having the same taper angle as that of the inner peripheral surface of the outer cylindrical portion. Hence, the cost of the wire storage container is high, and a wasted space is inevitably formed in the wire storage container (product) in which the welding wire is stored.
The wire storage container is slantingly placed on a disc-shaped baseplate having a circular projecting outer edge projecting upward from the inclined table provided on the lifting platform. Therefore, after insertion of the welding wire is finished, the wire storage container needs to be detached by being hoisted upward. Further, since the outer peripheral surface of the bottom of the wire storage container sometimes bores the inner peripheral surface of the projecting outer edge of the inclined table during hoisting, it takes much time to detach the wire storage container. While the wire storage container can be, of course, easily detached by using a special detaching device that lifts the wire storage container in an oblique direction and vertically lowers the wire storage container, this causes an economical problem, that is, a disadvantage in initial equipment cost.
In the wire storage apparatus of the related art, since the welding wire is merely stored in a distributed manner by being helically dropped into the wire storage container, the entire storage space in the wire storage container is not always effectively used to store the welding wire, and the storage rate (filling rate) of the welding wire is insufficient. In addition, during transportation by a truck or the like, the welding wire is moved in the wire storage container by vibrations of the wire storage container, and is tangled when paid out from the wire storage container. This interferes with a welding operation.
SUMMARY OF THE INVENTION
The present invention has been made in view of the above-described circumstances.
In order to solve the above problems, a welding-wire storage method according to an aspect of the present invention leads a welding wire paid out of a bobbin, via a dancer roller device and a capstan, into a wire guide chip provided on an outer peripheral surface of a conical flyer that rotates on a vertical axis, guides the welding wire downward, and helically drops and stacks the welding wire into a cylindrical container that rotates on a vertical axis below the flyer. The welding-wire storage method winds the welding wire led out of the dancer roller device onto a driving roller and a driven roller having flat winding surfaces in the capstan, guides the welding wire into the wire guide chip of the flyer, moves a lower end of the flyer close to an upper end of a stack of welding wire in the cylindrical container, and drops the welding wire into the cylindrical container while monitoring a close state between the upper end of the stack of welding wire and the lower end of the flyer in a state in which the vertical axis of the flyer is eccentric from the vertical axis of the cylindrical container.
According to the welding-wire storage method of the aspect of the present invention, the welding wire led out of the dancer roller device is wound around the flat winding surfaces of the driving roller and the driven roller in the capstan. Accordingly, even when a portion of the welding wire passing the driven roller of the capstan is wound on a position of the driving roller different from a portion of the welding wire led out of the dancer roller device, it does not move in the width direction of the driving roller, and is therefore not twisted. For this reason, the welding wire will not be tangled when being inserted in and paid out of the wire storage container.
Further, according to the welding-wire storage method of the embodiment of the present invention, the welding wire paid out of the double capstan and led into the wire guide chip of the flyer is helically stacked from the lower end of the flyer rotating on the vertical axis into the cylindrical container rotating on the vertical axis that is eccentric from the vertical axis of the flyer. Therefore, the structure of the cylindrical container is simple, unlike the wire storage container of the related art that includes the inner cylindrical portion shaped like a truncated cone and having the outer peripheral surface with the same taper angle as that of the inner surface of the outer cylindrical portion. Thus, the cost is low, and it is possible to prevent a wasted space from being formed in the cylindrical container in which the welding wire W is stored.
Further, the cylindrical container is rotated on the vertical axis, but is not placed slantingly, unlike the wire storage container of the related art. Therefore, it is necessary to prepare a special detaching device for obliquely lifting and vertically lowering the wire storage container. This provides an advantage in initial equipment cost of the welding-wire storage apparatus over the related art.
A distance between the lower end of the flyer and the upper end of the stack of the welding wire in the cylindrical container may be detected by a proximity sensor, and a height position of the cylindrical container may be controlled so that the distance is within a predetermined range. Alternatively, the welding wire may be stacked while vibrating the cylindrical container. Further alternatively, the welding wire may be stacked while beating an outer peripheral surface of a welding-wire storage portion of the cylindrical container.
According to these methods, since the welding wire helically dropped and stacked is closely stored in the cylindrical container, the storage rate (filling rate) of the welding wire is improved.
After the welding wire is inserted in the cylindrical container, the cylindrical container may be vibrated for a predetermined time. In this case, the welding wire is moved to a stable position in the cylindrical container, and is held in a state such as not to be moved by further vibration. Accordingly, since the welding wire stored in the cylindrical container will not be moved by vibration during transportation by a truck or the like, it can be reliably prevented from tangling when being paid out of the cylindrical container.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
A welding-wire storage apparatus that carries out a welding-wire storage method according to an embodiment of the present invention will be described below with reference to Figs. 1 to 4.
Referring to Fig. 1, a welding-wire storage apparatus 1 according to the embodiment is used to carry out the welding-wire storage method of the present invention. The welding-wire storage apparatus 1 mainly includes the following devices: (1) a wire dispenser 2 for paying out a welding wire W; (2) a dancer roller device 3 for keeping the tension of the welding wire W at a predetermined value; (3) a correction roller device 4 for correcting the welding wire W for deformation; (4) a double capstan 5 for pulling out the welding wire W at a predetermined fixed speed; (5) a wire storage device 6 for inserting the welding wire W in a cylindrical container 8; and (6) a roller way 7 for conveying the cylindrical container 8 to a storage space provided outside the welding-wire storage apparatus 1 after the welding wire W is inserted.
The wire dispenser 2 includes a driving motor (not shown) that rotates a detachably set bobbin 2a in order to pay out the welding wire W. The dancer roller device 3 includes a fixed roller 3a and a moving roller 3b on which the welding wire W paid out of the bobbin 2a is wound. The moving roller 3b moves up and down below the fixed roller 3a to absorb elongation of the welding wire W and to keep the tension of the welding wire W at a predetermined value. The correction roller device 4 includes a plurality of horizontal rollers (not shown) and a plurality of vertical rollers (not shown). The horizontal rollers are arranged in a staggered manner to oppose in the vertical direction, rotate on the horizontal axes, and are in rolling contact with the upper and lower sides of the running welding wire W. The vertical rollers are provided in a staggered manner to oppose in the right-left direction, rotate on the vertical axes, and are in rolling contact with the right and left sides of the running welding wire W.
In the welding-wire storage apparatus 1 of the embodiment, the correction roller device 4 is provided downstream of the dancer roller device 3 in the wire traveling direction, as described above. However, since no correction roller device is provided downstream of the dancer roller device in some welding-wire storage apparatuses, the present invention is not limited to the welding-wire storage apparatus 1 of the embodiment including the correction roller device 4.
The double capstan 5 includes an upper driving roller 5a on which the welding wire W corrected by the correction roller device 4 is wound, and a driven roller 5b provided on the left lower side of the driving roller 5a in Fig. 1. The driving roller 5a is rotated on the horizontal axis by a driving motor (not shown). The driven roller 5b is supported such as to freely rotate on the horizontal axis.
As shown in Fig. 2, the driving roller 5a and the driven roller 5b have flanges 5c on both widthwise sides thereof. Flat winding surfaces 5d for the welding wire W are provided between the flanges 5c.
After being corrected by the horizontal rollers and the vertical rollers in the correction roller device 4, the welding wire W is first laid on an upper side of the driving roller 5a, is turned to the left lower side, and is then laid on a lower side of the driven roller 5b. When being laid on the lower side of the driven roller 5b, the welding wire W is turned to the right upper side, and is laid on the upper side of the driving roller 5a. Subsequently, the welding wire W is turned downward, and is then supplied into the wire storage device 6 that will be described below.
Referring to Fig. 1, a pressing roller 5e is in contact with a right side of the driving roller 5a. The pressing roller 5e presses the welding wire W wound on the driving roller 5a.
The wire storage device 6 includes a frame 6a having an upper lateral member and a plurality of support column members for supporting the upper lateral member. The upper lateral member of the frame 6a supports a conical flyer 6b that is rotated on a vertical axis Li by a driving motor (not shown). Wire guide chips 6c each shaped like a short cylinder and having a wire insertion hole in which the substrate W is led are provided at regular intervals on an outer peripheral surface of the flyer 6b. The wire guide chips 6c helically guide the welding wire W, which is turned downward by the driving roller 5a of the double capstan 5, so that the helical diameter gradually increases toward the lower side of the flyer 6b.
The wire storage device 6 also includes a turntable 6d for rotating the cylindrical container 8 on a vertical axis L2 that is eccentric from the vertical axis Li of the flyer 6b. On the turntable 6d, a plurality of rotary rods 6e are arranged in parallel. The cylindrical container 8 is set on the rotary rods 6e so as to be fixed and unfixed by a detachable container fixing means (not shown).
The turntable 6d is supported by a vertical rotation shaft provided on a lifting table 6f that is vibrated by a vibrating means (not shown). On the lifting table 6f, there are provided a table driving motor 6g and a speed reducer 6h for reducing the rotating speed of the table driving motor 6g to a predetermined rotating speed and transmitting the reduced rotating speed to the rotation shaft. The lifting table 6f is moved up and down via a wire rope (not shown) connected to an extension rod of a hydraulic cylinder (not shown).
A rod protrudes downward from a lower side of the upper lateral member of the frame 6a. At a leading end of the rod, a proximity sensor 6i is provided to detect the distance from an upper end of the a stack of welding wire helically stored in the cylindrical container 8. The height position of the cylindrical container 8 is controlled so that the distance detected by the proximity sensor 6i is within a predetermined range. In other words, control is exerted so that the height of the lifting table 6f decreases as the storage amount of the welding wire W increases with continuation of the operation of inserting the welding wire W.
A container beating device 6j for beating an outer peripheral surface of a welding-wire storage portion of the cylindrical container 8 is provided under the upper lateral member of the frame 6a and at a position shifted from the rod for supporting the proximity sensor 6i. The container beating device 6j includes a swing rod that is pivotally attached at a base end to a bracket provided on the lower side of the upper lateral member via a shaft, a rod operating member, such as an air cylinder, for swinging the swing rod, and a beating member provided at a lower end of the swing rod to beat the outer peripheral surface of the cylindrical container 8.
Preferably, the distance detected by the proximity sensor 6i is kept at, for example, about 5 to 10 cm. If the distance is less than 5 cm, when the welding wire W is dropped in the cylindrical container 8, it interferes with an upper end of a stack of welding wire that has already been stored. This sometimes obstructs dropping of the welding wire W. In contrast, if the distance is more than 10 cm, it is difficult to drop the welding wire W in a normal helical form, and the welding wire W may tangle.
When the operation of inserting the welding wire W in the cylindrical container 8 placed on the turntable 6d is finished, it is necessary to detach the container fixing means and to move the cylindrical container 8 from the turntable 6d to the roller way 7. However, in a state in which the operation of inserting the welding wire W is finished, the cylindrical container 8 is located on the inner side of the frame 6a, and for example, the operator cannot enter the area where the cylindrical container 8 is located. For this reason, a container push-out device 9 shown in Fig. 3 is used to move the cylindrical container 8 out of the frame 6a,
The container push-out device 9 is provided on the lifting table 6f, and has an arm 9a for pushing the cylindrical container 8 out toward the roller way 7. A base end of the arm 9a is fixed to an upper surface of a reciprocating table 9b by a mechanical fastening means such as a bolt. The reciprocating table 9b is guided by a pair of guide rods 9e, and is reciprocated by a screw rod 9d that is rotated by a driving motor 9c.
After being moved onto the roller way 7 by the container push-out device 9 having the above-described structure, the cylindrical container 8 in which the welding wire W is stored is further moved to a product storage area via the roller way 7. The cylindrical container 8 is vibrated, for example, for about 30 seconds by a container vibrating device (not shown) provided in the roller way 7. The time period in which the container vibrating device vibrates the cylindrical container 8 is obtained from experience, and is not particularly limited to 30 seconds.
A description will be given below of an operation mode and advantages of the welding-wire storage apparatus 1 having the above-described configuration.
First, an empty cylindrical container 8 is placed on and fixed to the turntable 6d by the container fixing means. Then, the lifting table 6f is moved up. When the distance between the flyer 6b and a bottom surface of the cylindrical container 8 reaches a preset value, the upward movement of the lifting table 6f is stopped, and operation of the welding-wire storage apparatus 1 is started, so that the welding wire W is paid out of the bobbin 2a detachably set in the wire dispenser 2.
After the tension of the welding wire W paid out of the bobbin 2a is adjusted by movement of the moving roller 3b in the dancer roller device 3 closer to and away from the fixed roller 3a, the welding wire W is led into the correction roller device 4. The welding wire W corrected by the correction roller device 4 travels on the driving roller 5a, the driven roller 5b, and the driving roller 5a of the double capstan 5 in order, and is led into a plurality of wire guide chips 6c provided on the outer peripheral surface of the conical flyer 6b that rotates on the vertical axis Li in the wire storage device 6.
The welding wire W led in the wire guide chips 6c is guided downward along the outer peripheral surface of the flyer 6b while forming a helix whose diameter gradually increases. Below the flyer 6b, the welding wire W is dropped into the cylindrical container 8 that is being rotated on the vertical axis L2 by the turntable 6d. Since the vertical axis Li of the flyer 6b and the vertical axis L2 of the cylindrical container 8 are eccentric, the welding wire W dropped in the cylindrical container 8 is helically stacked and stored, as shown in Fig. 4.
During the above-described insertion of the welding wire W in the cylindrical container 8, the distance between the lower end of the flyer 6b and the upper end of the stack of welding wire in the cylindrical container 8 is detected by the proximity sensor 6i. By a hydraulic cylinder (not shown) controlled by a control device (not shown) for receiving a detection signal from the proximity sensor 6i, the lifting table 6f is moved down and the height of the cylindrical container 8 is controlled so that the distance detected by the proximity sensor 6i is within a predetermined range of 5 to 10 cm. Further, during the inserting operation of the welding wire W, the cylindrical container 8 is continuously vibrated via the lifting table 6f that is continuously vibrated by a vibrating means (not shown), and the outer peripheral surface of the welding-wire storage portion of the cylindrical container 8 is continuously beaten by the container beating device 6j.
When insertion of the welding wire W into the cylindrical container 8 is finished, the operation of the welding-wire storage apparatus 1 is stopped. Then, the welding wire W is cut near the lowermost wire guide chip 6c, the lifting table 6f is moved down until the flyer 6b comes out of the upper end of the cylindrical container 8, and, the container fixing means is detached from the turntable 6d. When the container fixing means is detached, the cylindrical container 8 is pushed from the interior of the frame 6a onto the roller way 7 by the arm 9a of the container push-out device 9.
The cylindrical container 8 pushed out onto the roller way 7 is conveyed to the container vibrating device (not shown) provided in the roller way 7. After the cylindrical container 8 is vibrated, for example, for about 30 seconds by the container vibrating device, it is further conveyed to the product storage area via the roller way 7. The cylindrical container 8 is covered with a lid in the product storage area, and is stored thereat until shipping.
According to the welding-wire storage method of the welding-wire storage apparatus 1 having the above-described configuration, the following great advantages can be obtained. That is, after being paid out of the bobbin 2a, led out of the dancer roller device 3, and corrected by the correction roller device 4, the welding wire W is wound on the flat winding surfaces 5d of the driving roller 5a and the driven roller 5b in the double capstan 5, as described above.
In this case, even when a portion of the welding wire W passing the driven roller 5b is laid on a position on the driving roller 5a different from a portion of the welding wire led out of the correction roller device 4, it does not move in the width direction of the driving roller 5a, and is not twisted. Accordingly, when being inserted into and paid out of the cylindrical container 8, the welding wire W does not tangle. In contrast, if the winding surfaces 5d of the driving roller 5a and the driven roller 5b of the double capstan 5 are not flat, but are shaped like, for example, ν'-shaped grooves that are concave toward the center, unlike the embodiment, the welding wire W is likely to be twisted. This is because the welding wire W passing the driven roller 5b easily moves in the width direction of the driving roller 5a (toward the V-shaped recesses of the winding surfaces 5d) along the groove shape.
According to the welding-wire storage method of the present invention, after the welding wire W is paid out of the driving roller 5a of the double capstan 5 and is led into the wire guide chips 6c of the flyer 6b, it is helically stacked from the lower end of the flyer 6b rotating on the vertical axis Li into the cylindrical container 8 rotating on the vertical axis L2 eccentric from the vertical axis Li. Accordingly, unlike the wire storage container of the related art, the cylindrical container 8 does not have an inner cylindrical portion shaped like a truncated cone and having an outer peripheral surface with the same taper angle as that of an inner peripheral surface of an outer cylindrical portion. Thus, the structure of the cylindrical container 8 is simple, and the cost is low. In addition, it is possible to prevent a wasted space from being formed in the cylindrical container 8 in which the welding wire W is stored.
According to the welding-wire storage method of the present invention, the cylindrical container 8 is rotated on the vertical axis L2 via the turntable 6d, but is not slantingly placed on an inclined table, unlike the wire storage container of the related art. Hence, it is unnecessary to prepare a special detaching device for obliquely lifting and vertically lowering the wire storage container. As a result, the welding-wire storage apparatus 1 has an advantage in initial equipment cost over the related art.
The height position of the cylindrical container 8 is controlled by moving down the lifting table 6f so that the distance between the lower end of the flyer 6b and the upper end of the stack of welding wire in the cylindrical container 8 detected by the proximity sensor 6i is within the predetermined range of 5 to 10 cm.
Further, while the welding wire W is being stacked, the cylindrical container 8 is continuously vibrated via the lifting table 6f vibrated by the vibrating means, and the outer peripheral surface of the welding-wire storage portion of the cylindrical container 8 is continuously beaten by the container beating device 6j. Therefore, the helically dropped and stacked welding wire W is closely stored in the cylindrical container 8. This improves the storage rate (filling rate) of the welding wire W.
Further, since the cylindrical container 8 is vibrated for a predetermined time (about 30 seconds) after the welding wire W is inserted therein, the welding wire W is moved to a stable position in the cylindrical container 8, and is held in a state such as not to be moved by further vibration. Accordingly, the welding wire W stored in the cylindrical container 8 will not be moved by vibration during transportation by a truck or the like. This reliably prevents the welding wire W from tangling when being paid out of the cylindrical container 8.
While the flyer 6b is conical in the above-described welding-wire storage apparatus 1, the shape of the flyer 6b is not limited thereto. The technical idea of the present invention can be applied to the welding-wire storage apparatus of the related art including the guide cylinder (corresponding to the flyer).
As described above, according to the present invention, when the welding wire is inserted into and paid out of the wire storage container, it will not tangle. Further, since the structures of the cylindrical container and so on are simple, the cost is low, and a wasted space is prevented from being formed in the cylindrical container in which the welding wire is stored. Therefore, the present invention is suitable for a storage apparatus and method for a welding wire that is produced by a high-efficiency production line, for example, a flux-cored welding wire that is produced by successively performing, with the same line, a step of rewinding and shaping a coiled hoop into a U-shaped hoop, a step of filling flux during shaping of the hoop, and a step of further wiredrawing and winding a tube-shaped wire filled with the flux.
