Description

Description: TECHNICAL FIELD The present invention relates to a method for manufacturing a twisted wire winding body, and more particularly to a method for manufacturing a wire winding body in which a wire is wound around a core tube without a collar.

2. Description of the Related Art As a type of a wire winding body in which a wire is wound, a wire wound while giving a certain twist to the wire is conventionally known.
The wire windings described in JP-A-54-49942, JP-A-57-199758 and the like are examples thereof.
The wire winding body, which is wound while giving a twist of 360 ° per winding, is twisted when the wire is pulled out in the axial direction of the wire winding body, so the wire winding body is rotated around the axis center. Without being twisted, the wire will be pulled out, and it is used for a winding body of a welding wire used as a welding electrode.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, such a conventional twisted wire winding body is a reel winding in which a wire is wound around a reel having flanges at both ends of a core tube, or a pail winding in which a wire is wound in a cylindrical drum. Was offered as. These reels and cylindrical drums are necessary for winding the wire, and are preferable in preventing the winding of the wire from collapsing even when they are carried out as a product, but they are not always necessary for consumers. It wasn't necessary and was disposable after the wire was used. Therefore, it is not preferable for saving resources,
Moreover, there is a disadvantage that the product cost is increased accordingly.

On the other hand, when a long object such as a hose or a rope is wound and bound, a plurality of notches are formed from the outer peripheral edge toward the center as described in, for example, Japanese Utility Model Laid-Open No. 60-146001. A core tube is arranged such that it cannot rotate relative to the formed pair of guide members and is relatively movable in the axial direction, and they are integrally rotated to wind a long object around the core tube and to wind the long object. It has been proposed that the core tube be withdrawn after bundling only the bodies, and the winding body made of only the long material is taken out from between the pair of guide members. However, if such a winding method is applied to a twisted wire winding device, not only a large-scale design change is required, but also in the case of a twisted wire, there is a force for returning the twist to the wire itself. Therefore, there is a problem that the winding shape may be broken and the wire may be entangled or entangled, and when the binding is released during use, the restraint at the end of the wire is released and the wire returns.

Means for Solving Problems The present invention has been made against the above circumstances.
The gist thereof is a method of manufacturing a wire winding body in which a wire twisted around an axis is wound around a core tube having a cylindrical shape. A pair of guide members in which the notch of

And (d) a step of winding the wire in the space of the reel while applying a predetermined tension while applying a constant twist to the wire by the twisted wire winding device,
(E) a step of winding a predetermined amount of wire around the reel, and then cutting the wire to fix the end portion, and (f) winding the reel around the wire by the transport device to the twisted wire. (G) fixing the wire to the core tube by winding the binding band around the wire through the plurality of notches, and (h) removing the wire from the winding tube. And a step of removing the pair of guide members.

Action That is, the reel on which the twisted wire should be wound,
A pair of decomposable guide members and a core tube are included,
First, a pair of guide members are detachably attached to both ends of the core tube to assemble a reel. Next, after the assembled reel is carried into a predetermined position of the twisted wire winding device by a carrying device and positioned, the tip of the wire is fixed to the reel or the carrying device, and the twisted wire winding device is held. The wire is wound around the reel while being given a certain twist and a predetermined tension. Since the guide member of the reel is attached so that its end surface is in close contact with both ends of the core tube, the twisted wire whose winding range is restricted by the guide member is wound around the entire length of the core tube. Become. When a predetermined amount of wire is wound around the reel, the wire is cut, the end portion is fixed to the reel or the like, and the wire is taken out from the twisted wire winding device by the transfer device. After that, by winding the binding band around the outer peripheral portion of the wire through the notch formed in the guide member,
By fixing the wire to the core tube and removing the guide member from the core tube, a wire winding body in which the wire is wound only on the core tube is manufactured. The guide member is attached to a new core tube and reused when the next wire winding body is manufactured.

EFFECTS OF THE INVENTION As described above, according to the present invention, a wire winding body in which a wire is wound around a core tube without a collar is obtained, so that the product cost is reduced as compared with the conventional reel winding or pail winding wire winding body. To be done. Further, since the guide member is attached to a new core tube and reused, it can contribute to resource saving.

On the other hand, the twisted wire is wound around the entire length of the core tube in a state where a predetermined tension is applied, and is fixed to the core tube with a binding band in that state, so that the winding shape is maintained well, There is no risk of the wire getting entangled or entangled due to the force to return the twist that it has, and even if the wire is untied at the time of use, the rear end of the wire, that is, the end on the side first wound around the core tube Since it can be constrained while being pressed by the core tube or fixed to the core tube, the twist does not return from the rear end side.
Further, since the method of the present invention manufactures a wire winding body in which a reel is disassembled and a wire is wound around a core tube without a collar, the conventional twisted wire winding device for winding a reel is used as it is. Therefore, the wire winding body can be manufactured at low cost without requiring a large design change of the device.

Embodiment Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a front view showing a twisted wire winding device. In FIG. 1, reference numeral 10 is a welding wire used as a welding electrode. The wire 10 is wound around the supply drum 12, and the motor 10 rotationally drives the supply drum 12 to rewind the wire 10 from the supply drum 12. The rewound wire 10 is pinched between a feed roller 18 that is rotationally driven by a motor 16 and a pinch roller 22 that is pressed against the feed roller 18 by a cylinder 20, and is accompanied by rotation of the feed roller 18. Are sent to the left in the figure. The motor 14 is driven in synchronization with the motor 16 so that the amount of the wire 10 unwound from the supply drum 12 becomes substantially the same as the amount of the wire 10 fed out by the feed roller 18. .

A step roll 24 and a straightener 26 are arranged between the rotary drum 12 and the feed roller 18. The step roll 24 is provided with a tension adjusting weight 28 so as to maintain the tension of the wire 10 between the supply drum 12 and the feed roller 18 substantially constant. The straightening machine 26 is composed of a plurality of rollers and repeatedly bends the wire 10 to straighten it.

The wire 10 sent out by the feed roller 18 is pulled out from the flexible guide tube 36 that is fixed in the guide cylinder 30 and is rotated around the reel 34 when the guide cylinder 30 is rotationally driven by the motor 32. And is wound around the reel 34. At this time, the wire 10 is twisted around the axis, but this twist is not transmitted to the upstream side of the portion pinched between the feed roller 18 and the pinch roller 22. The wire 10 wound around the wire is twisted by 360 ° per turn.

The tension of the wire 10 fed by the feed roller 18 is detected by the tension detector 38, and this tension is within a predetermined constant range, for example, 0.5.
The motor 16 is controlled to be maintained within the range of ~ 3.5 kg. As a result, the wire 10 is wound around the reel 34, and as the diameter of the wire 10 increases, the amount of the wire 10 sent out from the feed roller 18 also increases. With the tension of
It is wrapped around 34. Although the motor 32 drives the guide cylinder 30 to rotate at a constant rotation speed, the motor 32 is configured by including a powder clutch, a torque limiter, etc., and the tension of the wire 10 increases and the rotation resistance of the guide cylinder 30 becomes excessive. In such a case, slippage occurs and the tension of the wire 10 is adjusted to be substantially constant.

On the other hand, the reel 34 is mounted on the carriage 40, and
It is designed so that it can be carried in and out on the 42.
The lift table 42 is moved up and down by the screw shaft 46 being driven to rotate by the motor 44, whereby the wire 10 is wound around the outer periphery of the reel 34 substantially uniformly. The dolly 40 corresponds to a carrier device.

Here, as is clear from the exploded view of FIG. 2, the reel 34 includes a core tube 48 having a cylindrical shape and a pair of guide members 50 detachably attached to both ends of the core tube 48. ing. The pair of guide members 50 have exactly the same disc shape, have a larger diameter than the core tube 48, and have a plurality of notches 52 (four at 90 ° intervals in this embodiment) from the outer peripheral edge toward the center.
And a mounting hole 56 through which the shaft 54 erected on the dolly 40 is inserted is provided in the center. Further, one end surface 58 of the guide member 50 is provided with four ribs 60 radially, and the ribs 60 are provided.
Notches 62 are formed on the same circumference of 60, respectively.
It can be fitted into the upper end of the mounting tube 64 fixed to the. The core tube 48 is made of paperboard such as corrugated board or plywood, and the guide member 50 is made of metal. The other end surface 66 of the guide member 50 is substantially flat.

Next, only the core tube 48 of the reel 34 is connected to the wire 10
A method for manufacturing a wire winding body wound with will be described.

First, one guide member (hereinafter,
Place it with the lower guide member 50). Lower guide member
The end 50 is placed with the end surface 66 facing upward, the shaft 54 is inserted through the mounting hole 56, and the notch 62 formed in the rib 60 is fitted into the upper end of the placement tube 64. Next, the core tube 48 is placed concentrically on the lower guide member 50, and the other guide member (hereinafter referred to as the upper guide member) 50 is placed on the core tube 48. This upper guide member 50
Is mounted with the end face 58 facing upward so that the cutout 52 is located at substantially the same position as the cutout 52 of the lower guide member 50, and the shaft 54 is inserted into the mounting hole 56. Then, the nut 68 is attached to the male screw provided on the upper end of the shaft 54.
The guide members 50 are fixedly mounted on both ends of the core tube 48 by screwing, to form the reel 34, and are integrally mounted on the carriage 40. Since both guide members 50 are attached with their flat end surfaces 66 inside, they are closely attached to both ends of the core tube 48, and an annular space for winding the wire 10 is formed on the outer peripheral portion of the core tube 48. It

Next, the carriage 40 is moved onto the lifting table 42 of the twisted wire winding device shown in FIG. 1, and the reel 34 is positioned at a position substantially concentric with the guide cylinder 30.
At this time, the ascending table 42 is lowered to the lower end position, and the reel 34 is carried in without interfering with the guide cylinder 30. Then, after fixing the tip of the wire 10 extending from the tip of the guide tube 36 to the reel 34 or the trolley 40, the winding device is operated to twist the wire 10 by 360 ° per turn. Reel 34 core tube 48
Wrapped around. Since the guide members 50 are attached to both ends of the core tube 48, the wire 10 is not attached to those guide members.
It is wound in the annular space formed by 50.

Here, such a twisted wire winding body returns the twist of the wire when the wound wire is pulled out,
A twist-free wire is obtained without rotating the winding body. Therefore, it is possible to wind a wire without twisting, and to wind a large capacity wire as compared with the case of rotating the winding body when pulling out, and in this embodiment, the wire 10 of about 250 to 500 kg is wound. It is supposed to turn.

When the predetermined amount of the wire 10 is wound in this way, the winding device is stopped and the lift table 42 is lowered to the lower end position. Then, after the wire 10 is cut, the carriage 40 is moved from the elevating table 42, so that the reel 34 around which the wire 10 is wound is carried out. FIG. 3 shows the reel 34 carried out from the winding device in this manner. The cut end of the wire 10 may be connected to the rib 60 or the like of the upper guide member 50 as shown in FIG. 3, for example.

Subsequently, the binding band 70 is passed through the notch 52 formed in the guide member 50 into the cylinder of the core tube 48, and is wound around the outer periphery of the wound wire 10 in a roll shape.
The four positions in the circumferential direction of are fixed to the core tube 48. FIG. 4 is a view showing this state, and the notch 52 is formed with a length that reaches the position intersecting with the core tube 48. The binding band 70 prevents the roll-shaped wire 10 from collapsing, and various types such as a string and a tape can be adopted. In addition, a hooking portion is provided in advance on both ends of the core tube 48, and both ends of the binding band can be hooked on the hooking portion,
Alternatively, one end of the binding band may be fixed to the core tube 48 in advance, and the binding form of the binding band may be appropriately changed.

Finally, the nut 68 that secures the guide member 50 to the core tube 48.
Is loosened and removed from the shaft 54, the upper guide member 50 is removed, and then the roll-shaped wire 10 is taken out together with the core tube 48 and placed on the pallet 72. As a result, the wire winding body 74 in which the wire 10 is wound only around the core tube 48 having no collar is obtained. FIG. 5 is a view showing this state, and thereafter, the wire winding body 74 is conveyed while being placed on the pallet 72 in this manner.

On the other hand, when manufacturing a new wire winding 74 next,
A new core tube 48 is concentrically mounted on the lower guide member 50 which is still mounted on 40, and the upper guide member 50 is mounted on the core tube 48 and the nut 68 is loosened. Thus, a new reel 34 is constructed. Thereafter, a new wire winding body 74 is manufactured by the same operation as described above.

Thus, in this embodiment, when the wire 10 is wound around the core tube 48 while being twisted by the wire winding device, the reel 34 is configured by attaching the guide members 50 to both ends of the core tube 48. Then, the wire 10 is wound around the reel 34 in the same manner as the conventional reel winding, and then the binding band 70 is wound around the outer periphery of the wire 10 to fix the wire 10 to the core tube 48, and then the upper guide. The member 50 is removed and the roll-shaped wire 10 is taken out together with the core tube 48 from the lower guide member 50. Therefore,
The wire winding body 74 manufactured in this manner is in a state in which the wire 10 is wound only on the core tube 48 having no collar, and the wire winding body is formed by the conventional reel winding shown in FIGS. 6 and 7. The product cost is reduced as compared with the wire winding body 82 of 80 or pail winding. Further, since both guide members 50 are attached to the new core tube 48 and are used for both, it can contribute to resource saving.

On the other hand, the wire 10 has a core tube 48 with a predetermined tension applied.
Is wound all over the length of the
Since it is fixed to the core tube 48 by 70, the winding shape is maintained in a good condition, and there is no fear that the wire 10 will be entangled or entangled due to the force to return the twist of the wire 10 itself, and the wire 10 should be bundled during use. Even if unraveled, the rear end of the wire 10, that is, the end on the side first wound around the core tube 48 is the core tube.
Since it can be constrained in a state of being pressed by 48 or fixed to the core tube 48, the twist does not return from the rear end side. Further, since the reel 34 can be disassembled to manufacture the wire winding body 74 in which the wire 10 is wound around the core tube 48 having no collar, the conventional twisted wire winding device for reel winding can be used as it is. Therefore, the wire winding body 74 can be manufactured at low cost without requiring a large design change of the device.

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

For example, in the above embodiment, the welding wire 10
Although the case of manufacturing the wire winding body 74 wound while giving a twist of 360 ° has been described, it can be similarly applied to the case of manufacturing another type of wire winding body of the present invention.
Further, the amount of twist is not necessarily limited to 360 ° per turn.

Further, although the disk-shaped guide member 50 is used in the above-described embodiment, it is needless to say that a guide member having another shape such as a square shape or a cross shape can be adopted, and the core tube 48 is used.
The material of the guide member 50 can be changed as appropriate.

Further, in the above-described embodiment, the nut 34 is screwed onto the shaft 54 provided upright on the truck 40 to form the reel 34 integrally assembled to the truck 40. Can be configured as a separate body, or other attaching / detaching means can be adopted.

Further, in the above-described embodiment, the wire 10 is wound by the twisted wire winding device shown in FIG. 1, but such a winding device is merely an example, and at least when carrying out the present invention, As long as the wire 10 can be wound around the reel 34 while being twisted, various other devices can be adopted.

Although not illustrated one by one, the present invention can be carried out in variously modified and improved modes based on the knowledge of those skilled in the art without departing from the spirit thereof.
