Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a twisted wire winding body.

[0002]

2. Description of the Related Art A type of wire wound body in which a wire is wound,
It is known that a wire is wound while being given a certain twist. For example, a twisted wire winding body in which a wire is wound around a brimless core tube described in JP-A-63-68221, a pail winding in which a wire is wound in a cylindrical container, and the like are available. That is it. For example, in a wire winding body that is wound while giving a twist of 360 ° per winding, the twisting of the wire is returned when the wire winding body is pulled out in the axial direction of the wire winding body. A wire that is not twisted is drawn out without rotating and is used for a winding body of a welding wire used as a welding electrode.

[0003]

In the pail winding as described above, a cylindrical container having an opening at the upper end is rotated around its axis, and at the same time, it has an opening on the bottom surface side which is its closed end and has its axial direction. A wire is guided to the closed end side through a predetermined guide member that is rotated about another axis parallel to the center of an eccentric shaft that relatively rotates the wire about the axis of the cylindrical container. It is manufactured by laminating while winding along one circumference. Therefore, the wire accommodated in the cylindrical container is twisted based on the relative rotation between the guide member and the cylindrical container.

By the way, in the pail winding, since it is necessary to store a wire having a predetermined weight in a cylindrical container having a predetermined size defined by a standard, when manufacturing the pail winding as described above, a cylinder is used. The filling volume is increased by vibrating the cylindrical container while supplying the wire into the cylindrical container. Therefore, vibration is also applied to the wire, but since the wire is twisted and distorted when being stacked while being wound in the cylindrical container, the strain is released by the vibration and the wire is distorted. There was a problem of flapping. When the wire flaps as described above, the wire comes into contact with the guide member and is wound around the guide member, making it impossible to wind the wire. It will decrease. In the present application, the “ring diameter” refers to the diameter of each layer of the wire that is spirally laminated in the cylindrical container.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a method and an apparatus for manufacturing a twisted wire winding body capable of suitably suppressing the fluttering of the wire.

[0006]

In order to achieve such an object, the gist of the method for producing a twisted wire winding body of the first invention is that a shaft is provided in a cylindrical container having an open upper end. Method for manufacturing twisted wire winding body in which wire having twist about its center is wound and wound along a circle around an eccentric shaft that rotates relative to the axis of the cylindrical container And (a) attracting the wire in the cylindrical container from the outside of the cylindrical container using a magnet in the vicinity of the minimum distance between the inner circumferential surface of the cylindrical container and the one circumference. It is to include a wire suction step.

[0007]

[Effects of the First Invention] According to this structure, in the wire suction step, the distance between the inner peripheral surface of the cylindrical container and the one circumference centered on the eccentric shaft that relatively rotates about its axis is minimized. In the vicinity, the wire in the cylindrical container is attracted from outside the cylindrical container using a magnet. Therefore, the wire that is laminated while being wound in the cylindrical container is
Near the distance to the inner peripheral surface of the cylindrical container is the minimum, that is, near the outermost position, because it is attracted to the inner peripheral surface of the cylindrical container, even if vibration is given The movement of the wire in the stacked plane and in the stacking direction is suppressed, and the wire is held at the stacked position. Therefore, the fluttering of the wire is suppressed, and the occurrence of the wire entanglement, the variation in the ring diameter, and the like are preferably suppressed.

[0008]

[Other Aspects of the First Aspect of the Invention] Preferably, in the method for manufacturing the twisted wire winding body, (b) the magnet is positioned on a laminating surface of the wire laminated in the cylindrical container. As described above, the method further includes a magnet moving step of relatively moving the magnet and the cylindrical container along the axial direction of the cylindrical container in synchronization with the moving speed of the stacking surface.

With this configuration, in the magnet moving step, the magnet for attracting the wire in the cylindrical container is positioned along the axial direction of the cylindrical container so that the magnet for attracting the wire is located on the laminating surface of the wire. The container and the container are moved relative to each other in synchronization with the moving speed of the stacking surface. Therefore, since the wire in the cylindrical container is attracted by the magnet that is relatively moved in synchronization with the moving speed of the stacking surface, it is possible to prepare a plurality of magnets along the axial direction of the cylindrical container.
It is possible to sequentially draw the accommodated wires using only one magnet. In the present application, the term “laminating surface” refers to a cylindrical end surface of a wire that is spirally stacked in a cylindrical container to form a substantially cylindrical wire.

[0010]

A second aspect of the present invention for producing a twisted wire winding body for attaining the above-mentioned object is to provide a twisted wire winding body in a cylindrical container having an open upper end. , A twisted wire winding for winding and accommodating a wire given a twist about its axis along a circle centered on an eccentric axis that rotates relative to the axis of the cylindrical container A body manufacturing apparatus, (c) a guide member having an opening at the lower end side and being rotated around the eccentric axis to guide the wire to the lower end side of the cylindrical container, (d) the cylindrical shape A magnet for attracting the wire in the cylindrical container, the magnet being provided outside the cylindrical container in the vicinity of the minimum distance between the inner peripheral surface of the container and the opening of the guide member. .

[0011]

In this way, the wire of the cylindrical container can be rotated by rotating the wire around the eccentric shaft, that is, another axis parallel to the axis of the cylindrical container while having the opening on the lower end side. A guide member that guides to the lower end side, and the wire inside the cylindrical container that is provided outside the cylindrical container in the vicinity of the minimum distance between the inner peripheral surface of the cylindrical container and the opening of the guide member. An apparatus for manufacturing a twisted wire winding body is configured including a magnet for attracting. for that reason,
Since the guide member and the cylindrical container are respectively rotated about different axes, the distance between the opening of the guide member and the inner peripheral surface of the cylindrical container is changed according to the rotation angle of the guide member. , The wire stored in the cylindrical container is
It is laminated while being wound around a circle around the eccentric axis. In this case, the magnet for attracting the wire should be provided near the minimum distance between the opening of the guide member and the inner peripheral surface of the cylindrical container, that is, near the position where the wire is closest to the outer peripheral side. Therefore, even if vibration is applied, the wire is restrained from moving in the stacked plane and in the stacking direction, and held at the stacked position. Therefore, the fluttering of the wire is suppressed, and the occurrence of the wire entanglement, the variation in the ring diameter, and the like are preferably suppressed.

[0012]

[Another aspect of the second aspect of the invention] Here, preferably, the manufacturing apparatus of the twisted wire winding body comprises: (e) the magnet and the cylindrical container so that the magnet is located on the laminating surface of the wire. It further includes a relative movement device for relatively moving and along the axial direction of the cylindrical container.

With this configuration, the magnet further includes a relative movement device for relatively moving the magnet and the cylindrical container along the axial direction so that the magnet for attracting the wire is located on the laminated surface of the wire. An apparatus for manufacturing a twisted wire winding body is configured. Therefore, since the magnet for attracting the wire in the cylindrical container is relatively moved in synchronization with the moving speed of the laminated surface, without preparing a plurality of magnets along the axial direction of the cylindrical container, It becomes possible to sequentially attract the accommodated wires using only one magnet.

[0014]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an apparatus 10 for manufacturing a twisted wire winding body according to an embodiment of the present invention. In the figure, 12 is a welding wire used as a welding electrode (hereinafter, simply referred to as wire 12). The wire 12 is wound around the material supply drum 14, and the material supply drum 14 is rotationally driven by the motor 16 to generate the wire 1.
2 is rewound from the material supply drum 14. The unwound wire 12 is wound once around a feed drum 20 which is rotationally driven by a motor 18, and the feed drum 2
With the rotation of 0, it is sent to the right side of the drawing from the material supplying drum 14 and is sent below the material supplying drum 20. The motor 16 is driven in synchronization with the motor 18 so that the amount of the wire 12 unwound from the material supply drum 14 becomes substantially the same as the amount of the wire 12 delivered by the supply drum 20. The material supply drum 14
Proximity switch 2 for measuring the rotation speed near the
6 are provided.

A step roll 28 and a straightener 30 are arranged between the material feeding drum 14 and the feeding drum 20. The step roll 28 includes a roller 32 that functions as a weight for tension adjustment, and maintains the tension of the wire 12 between the material feeding drum 14 and the feeding drum 20 substantially constant. Further, the straightener 30 includes a plurality of rollers (not shown), and repeatedly bends the wire 12 to straighten it.

Below the feed drum 20, a cylindrical guide head 36 is provided which is driven to rotate about its axis by a motor 34. The guide head 36 is formed in a cylindrical shape whose lower end side is open, and a guide tube 38 is fixed to the inner peripheral surface of the guide head 36 so as to draw a spiral from the upper end of the cylindrical shape toward the lower end. This guide head 3
A protective wall 42 that covers the guide head 36 up to the lower end 40 is provided on the side of 6 to secure the safety of the operator, and a magnet 44 is attached to the lower end of the protective wall 42. In this embodiment, the guide tube 38 corresponds to the guide member.

As shown in an enlarged view in FIG. 2, the magnet 44 has a circle so that it is located below the arcuate member 46 having an L-shaped cross section fixed to the lower end of the inner peripheral surface of the protective wall 42. A U-shaped bolt 50 is attached to the lower surface of a mounting jig 48 fixed to the upper side of the arc-shaped member 46 by rivets or the like. That is, this magnet 44 is
The position of 6 is fixed so as to be immovable in both the axial direction and the circumferential direction. The motor 34 drives the guide head 36 to rotate at a constant rotation speed.
The guide head 36 is provided with a powder clutch, a torque limiter, etc. to increase the tension of the wire 12.
When the rotation resistance of the wire becomes excessive, slippage occurs, and the tension of the wire 12 is adjusted to be substantially constant.

Further below the guide head 36,
A pail pack 52 for accommodating the wire 12 is provided so as to be movable up and down along the axial direction. In this embodiment, the pail pack 52 corresponds to a cylindrical container. It should be noted that FIG. 1 shows a state in which the pail pack 52 has been lowered to the lowermost end, in a winding end state or before winding start. The pail pack 52 is formed in a cylindrical shape with a bottom whose upper end side is open. However, as shown in the cross section of FIG. 3, the pail pack 52 is provided on the inner peripheral side thereof with an inner cylinder coaxial with an outer cylinder 54 forming an outer edge portion. The cylinder 56 is erected from the bottom surface 58 (that is, the inner surface of the closed end that is the lower end). The guide head 36 is formed to have a diameter smaller than that of the outer cylinder 54 and larger than that of the inner cylinder 56.
2 is fully raised above the position shown in FIG.
For example, as shown in FIG. 3, the lower end 4 of the guide head 36 is
When 0 is below the upper end of the pail pack 52, the guide head 36 is located between the outer cylinder 54 and the inner cylinder 56.

Therefore, in the wire 12 fed downward from the feeding drum 20, the guide tube 36 is rotationally driven by the motor 34 so that the guide tube 38 has the inner tube 5.
6 is rotated around 6, the lower end of the guide tube 38 (that is, the bottom surface 58 side of the pail pack 52)
The pail pack 5 is pulled out from the opening 60 provided in the
2 is stored. At this time, the wire 12 is twisted around the axis, but since this twist is not transmitted to the upstream side of the feeding drum 20, the wire 12 housed in the pail pack 52 is eventually wound by one winding. Each is given a twist of 360 °.

Returning to FIG. 1, the pail pack 52 is
The vibrating device 66 is mounted on the carriage 62 and is mounted on the elevating base 64 so that it can be carried in and out. The elevating table 64 can be moved up and down by rotating the screw shaft 68 by a motor (not shown). As a result, during the winding of the wire 12 into the pail pack 52, the elevating table 64 is lowered at a predetermined speed according to the pulling speed of the wire 12, and as shown in FIG. 52
The distance h between the stacking surface of the wire 12, which is being housed in a spiral shape, that is, the upper end surface 70 and the tip of the guide head 36 is kept substantially constant. These distances h and d are, for example, about 40 to 80 (mm) and about 20 (mm), respectively.

The magnet 44 is formed by the guide head 36.
It is fixed at a position vertically separated from the lower end 40 by the above distance h and separated from the outer peripheral surface of the pail pack 52 by a predetermined distance d. Therefore, the pail pack 52
The magnet 44 is always located on the laminating surface 70 of the wire 12 in the axial direction of. Further, on the upper side of the vibrating device 66, a rotary table 74 that is rotationally driven by a motor 72 is provided, and the pail pack 52 is also rotated at a constant speed.
In this embodiment, the turntable 74 corresponds to a rotating device. That is, the guide head 36 and the pail pack 5
Both 2 are rotated about their axis. However,
Rotational speed of the pail-pack 52 with the both sufficiently slower than the rotational speed of the guide heads 36 are rotated relative to, both the axial center C _h as shown in FIG. 3, C _p
Do not agree with each other.

Therefore, the wire 12 is connected to the guide head 3
6, the guide tube 38 provided in the inside of the pail pack 52, that is, the opening 60 at the lower end on the bottom surface 58 side of the pail pack 52, and another axis C parallel to the axis C _p of the pail pack 52.
It is guided into the pail pack 52 through the guide tube 38 rotated about _h . As is clear from the figure, the distance a between the outer peripheral surface of the guide head 36 and the inner peripheral surface of the pail pack 54 is different depending on the rotation angle position around the axis C _h or C _p. There is. The opening 60 of the guide tube 38 has an interval a of 40, for example.
The magnet 44 is provided at a position where it has a minimum value of about (mm), and the magnet 44 is provided outside the portion where the distance a = 40 (mm), that is, the portion where the opening 60 is provided.

A method of manufacturing the wire winding body 12a by the twisted wire winding body manufacturing apparatus 10 configured as described above will be described.

First, in FIG. 1, the pail pack 52 is placed on the trolley 62 while the trolley 62 is positioned on the rail 76 provided on the right side of the lift 64 or the like.
Then, the elevating table 64 is moved to the lowermost position and moved onto the rotating table 74 to position the pail pack 52 so that its axis coincides with the rotating axis of the rotating table 74. On the other hand, the wire 12 wound around the material supply drum 14
Is extended from the opening 60 at the tip of the guide tube 38 via the step roll 28, the straightener 30, and the feeding drum 20. Then, the elevating table 64 is raised to a position where the distance between the uppermost end, that is, the lower end 40 of the guide head 36 and the bottom surface 58 of the pail pack 52 is the distance h, and the material feeding drum 1
4. The wire 12 is housed in the pail pack 52 by rotating the feeding drum 20 and rotating the guide head 36 and the pail pack 52 around the axis at the same time. In the present embodiment, the rotating process is performed by rotating the pail pack 52 around the axis.
The guiding steps are each carried out by passing the wire 12 through the wire 8 and out of its opening 60.

At this time, in order to increase the filling volume of the wire 12 and store the wire 12 in the pail pack 52 by a predetermined weight, the vibrating device 66 is driven during storage and vibration is applied to the pail pack 52. However, the wire 12
Is stored in the pail pack 52 while being twisted by 360 ° per roll based on the rotation of the guide head 36. Therefore, due to the restoring force of the twisted wire 12 and the vibration, the wire 12 tends to jump up when being stacked in the pail pack 52. In this case, in this embodiment, since the magnet 44 is provided outside the height position of the laminated surface 70 of the wire 12, when the wire 12 is extended to the position where the distance a is minimized, The magnet 44 attracts the wire 12 to suppress its bouncing or “fluttering”. In this embodiment, this step corresponds to the wire suction step. Therefore, the wire 12 is stored with a predetermined ring diameter without bouncing up and coming into contact with the guide head 36, and when the wire 12 is pulled out at a withdrawing speed of, for example, about 260 (m / min) after being stored, most of the wire 12 Mutual entanglement does not occur. The above drawing speed is sufficiently higher than the drawing speed (about 10 [m / min]) when welding is performed using the wire 12.

As described above, since the guide head 36 and the pail pack 52 are respectively rotated about different rotation axis centers C _h and C _p , the layers of the layers stacked as shown in FIG. The instantaneous center of the wire 12 (that is, the axis C _h of the guide head 36) is the pail pack 52.
Relative rotation about the axis C _p of the. Therefore, the locus of the opening 60 at the tip of the guide tube 38 on the pail pack 52, that is, the shape of the wire 12 (wire winding body 12a) pulled out from the opening 60 into the pail pack 52 and viewed from the upper surface is the pail. A large number of circles having a diameter smaller than that of the inner peripheral surface of the pack 52 form a petal shape formed by being inscribed at a plurality of positions on the inner peripheral surface. That is, the wire 12, the guide head 36 is eccentric shaft to rotate relative to the axis C _p around the pail-pack 52
It is wound along one circumference centered on the axis C _h of. Therefore, when the wire 12 stored in the pail pack 52 is pulled out and used, the wire 12 is prevented from being unwound more than necessary.

In the process of stacking the wires 12 in the pail pack 52 in this way, when the stacking surface 70 of the wires 12 rises according to the stored amount, the lifting table 64 is moved by a height corresponding to the lifted amount. Can be lowered. As a result, the height of the laminated surface 70 is kept substantially constant, the distance between the lower end of the guide head 36 and the laminated surface 70 is maintained in an appropriate state, and the magnet 44 is positioned at the height position of the laminated surface 70. The wire 12 is positioned so that the wire 12 is prevented from jumping up during the entire time from the start to the end of the winding operation.
That is, in the present embodiment, the lifting table 64 corresponds to a relative moving device, and the magnet moving process is always executed during winding of the wire, so that the magnet 44 and the pail pack 52 move in the axial direction of the pail pack 52. Along with this, the laminated surface 70 is relatively moved in synchronization with the moving speed of the laminated surface 70.

When the elevating table 64 is lowered to a predetermined position and a predetermined amount of wire 12 is stored in the pail pack 52 as described above, the motors 16, 18, 34, 72 are moved.
Etc. are stopped, and the lift base 64 is lowered to the lower end position. Then, after cutting the wire 12, the carriage 62 is moved from the rotary table 74 to carry out the pail pack 52 in which the wire 12 is housed, thereby completing the series of manufacturing processes of the twisted wire winding body. To be

In the twisted wire winding body manufactured as described above, the twist of the wire 12 is returned when the wound wire 12 is pulled out, so that the twisted wire 12 is not rotated without rotating the pail pack 52. can get. Therefore, the wire 12 can be wound without being twisted, and a large capacity of the wire 12 can be stored as compared with the case where the pail pack 52 is rotated when the wire 12 is pulled out.
The wire 12 of about 0 to 350 (kg) is accommodated.

Here, FIG. 5 is a view showing the quality of the twisted wire winding body described above in comparison with the twisted wire winding body manufactured by a conventional manufacturing apparatus in which the magnet 44 is not used. (a) shows the variation in the diameter of the storage wheel in the pail pack 52, and (b) shows the line gutter when the wire 12 is pulled out from the pail pack 52. The storage wheel diameter variation is obtained by measuring the variation in the diameter D of each layer of the wire 12 laminated in a petal shape as shown in FIG. Further, as shown in FIG. 6, the straight line is put on the upper end surface 70 of the wire 12 in the pail pack 52 by pulling out the wire 12 and pulling out the wire 12 and cutting it by a predetermined length of, for example, about 2 (m) The waviness rate (W / L), which is the size (W) of the waviness per unit length (L) when placed on the floor, and the rising (H), that is, the size of the bouncing of the wire 12 when placed on a plane. Is measured.

As is clear from the figure, according to the present embodiment, the variation in the diameter of the storage ring is smaller and the linear crease tends to be improved as compared with the case where the magnet 44 is not used.
The values shown in these figures represent the winding speed when the wire 12 is stored in the pail pack 52, for example, 1000
(m / min) represents the quality. Generally, the higher the winding speed is, the lower the quality tends to be. Therefore, when the winding speed is slow, the variation in the wheel diameter and the linear squeeze are further reduced.

By the way, the twisted wire winding body as described above is used, for example, in a welding robot 8 as shown in FIG.
It is used for supplying the wire 12 as a welding electrode in the welding operation by 0. In the welding operation using the welding robot 80, the pail pack 52
The wire 12 pulled out of the torch 82 is projected from the tip of the torch 82 toward the welded portion. In such a welding operation, it is desirable that the wire 12 surely faces the target position of the welded portion. FIG. 8 shows the result of a punching test in which the amount of deviation from the target position when the wire 12 is projected toward the welded portion is evaluated. In the figure,
The abscissa indicates the position number of the wire 12 every 150 (mm), that is, the number of times of measurement, and the ordinate indicates the coordinate positions in the x-axis direction and the y-axis direction.

In the punching test, as shown in FIG. 7, the wire 12 is projected toward the test table 84, and the target position on the test table 84 is set as the origin (x = 0, y = 0) and the x-axis is set. The values of x and y at the position where the wire 12 hits are read in orthogonal coordinates with the y axis taken in an appropriate direction. Figure 7
The protrusion length indicated by E (that is, the distance from the tip of the torch 82 to the test table 84) was about 150 (mm), and the wire 12 was cut at the tip of the torch 82 at each protrusion. As a result, the deviation from the target position at each position of the wire 12 of 150 (mm) is measured.

FIG. 8 shows the measurement results when the wire 12 is housed in the pail pack 52 at a winding speed of 1000 (m / min), for example. According to the embodiment, even when the winding speed is high as described above, the deviation from the target position is sufficiently reduced. On the other hand, FIG. 9 shows a conventional manufacturing apparatus in which the magnet 44 is not used, for example, a twisted wire winding in which the wire 12 is wound into the pail pack 52 at a low speed of about 600 (m / min). Although the results of the same evaluation of the body are shown, the deviation from the target position is slightly large, although the body is wound at a lower speed than in the present embodiment. As described above, considering that the quality of the twisted wire winding tends to decrease as it is wound at a higher speed, it is clear that the straight line is greatly improved in this embodiment.

In short, in the present embodiment, in the wire suction step, the guide head 36, which is an eccentric shaft that relatively rotates about the inner peripheral surface of the pail pack 52 and its axial center C _p.
Of the magnet 4 from the outside of the pail pack 52 in the vicinity of the minimum distance a from the circumference centered on the axis C _h of the magnet.
4 is used to attract the wire 12 in its pail pack 52. Therefore, the wire 12 laminated while being wound in the pail pack 52 is
Since the wire 12 is attracted to the inner peripheral surface of the pail pack 52 in the vicinity of the position where the distance from the inner peripheral surface is minimum, that is, in the vicinity of the position on the outermost peripheral side, even if vibration is applied, the wire 12 The movement within the stacked surface 70 and in the stacking direction is suppressed, and the stacked surface 70 is held at the stacked position. Therefore, the fluttering of the wire 12 is suppressed, and the occurrence of the entanglement of the wire 12 and the variation in the ring diameter are appropriately suppressed.

Further, in the present embodiment, when the laminating surface 70 of the wire 12 rises according to the stored amount, the elevating table 64 is lowered in the magnet moving step by a height corresponding to the raised amount, and the laminating layer 64 is laminated. The height of the surface 70 is kept substantially constant, the distance between the lower end of the guide head 36 and the laminated surface 70 is maintained in an appropriate state, and the magnet 44 is positioned at the height position of the laminated surface 70. That is, the magnet 44 and the pail pack 52 are arranged along the axis _Cp direction of the pail pack 52 so that the magnet 44 for attracting the wire 12 in the pail pack 52 is substantially located on the laminating surface 70 of the wire 12. And are relatively moved in synchronization with the moving speed of the stacking surface 70. Therefore, since the wire 12 in the pail pack 52 is attracted by the magnet 44 that is relatively moved in synchronization with the moving speed of the stacking surface 70, a plurality of magnets 44 are prepared along the axial direction of the pail pack 52. Without this, it is possible to sequentially attract the accommodated wires 12 using only one magnet 44.

Further, in this embodiment, the opening 60 is provided on the lower end side, and it is rotated about the axis C _h of the guide head 36 which is another axis parallel to the axis C _p of the pail pack 52. A guide tube 38 for guiding the wire 12 to the lower end side of the pail pack 52;
And a magnet 44 for attracting the wire 12 in the pail pack 52, which is provided outside the pail pack 52 in the vicinity of the minimum distance a between the inner peripheral surface of the pail pack 38 and the opening 60 of the guide tube 38. A manufacturing apparatus 10 for a wound wire roll is configured. Therefore, the guide tube 38 and the axis C _h different from the pail-pack 52, from being rotated each C _p around, the distance a between the inner peripheral surface of the opening 60 and the pail-pack 52 of the guide tube 38 that guides The wire 1 which is changed according to the rotation angle of the tube 38 and is housed in the pail pack 52.
The two are laminated while being wound around a circle having the axis C _h as the center. In this case, the magnet 44 for attracting the wire 12 is located near the minimum distance a between the opening 60 of the guide tube 38 and the inner peripheral surface of the pail pack 52, that is, near the position where the wire 12 is closest to the outer peripheral side. Therefore, even if vibration is applied to increase the filling bulk, movement of the wire 12 in the surface 70 where the wires 12 are stacked and in the stacking direction is suppressed,
It will be held in the laminated position. Therefore, the fluttering of the wire 12 is suppressed, and the occurrence of the entanglement of the wire 12 and the variation in the ring diameter are appropriately suppressed.

Further, according to this embodiment, the wire 12 is pulled.
The magnet 44 for tightening is placed on the laminated surface 70 of the wire 12.

Although one embodiment of the present invention has been described in detail with reference to the drawings, the present invention can be implemented in still another mode.

For example, in the embodiment, the magnet 44 is always positioned on the laminating surface 70, but if the magnet 44 has a sufficiently strong magnetic force, it may be positioned slightly below the laminating surface 70. It may be provided. In this way, the wire 12 is attracted slightly downward, so that the fluttering of the wire 12 can be suppressed more reliably. It should be noted that the magnet 44 may be provided above the stacking surface 70 within a range in which the fluttering of the wire 12 can be sufficiently suppressed.

Further, in the embodiment, the distance d between the magnet 44 and the pail pack 52 is set to, for example, about 20 (mm), but this distance is appropriately set according to the diameter of the pail pack 52, the magnetic force, and the like. It

Further, in the embodiment, the magnet 44 is provided at the lower end of the protective wall 42 provided on the side of the guide head 36, but the height position of the wire 12 with respect to the laminating surface 70 is substantially constant. If the position of the pail pack 52 in the circumferential direction is fixed, another member, for example, the screw shaft 68.
It does not matter even if it is attached to the upper end of the or other member that is erected separately.

In the embodiment, the magnets 44 are moved relative to the stacking surface 70 by lowering the elevating table 64, but the magnets 44 are moved along the axial direction of the pail pack 52 over substantially the entire length thereof. Multiple magnets or a sufficiently long magnet 4
If 4 is provided, no relative movement of magnet 44 is required. In such a case, for example, the magnet 44 can be provided on the lift table 64.

In the case where the magnet 44 is provided on the lift table 64, a plurality of electromagnets may be provided along the axial direction of the pail pack 52 to be turned on / off in synchronization with the rising speed of the stacking surface 70. Good. By doing so, the magnet 44 is substantially moved relatively.

Although not specifically exemplified, the present invention
Various changes can be made without departing from the spirit of the invention.
