Description

  The present invention relates to a traverse device and a traverse method for winding a metal wire such as a steel cord, a bead wire and a piston ring wire, a covered wire such as an electric wire, and a wire (wire material) such as a rope onto a reel by aligned winding. .

  As a method of winding the wire around the reel, the wire is guided to the reel body via a guide roller (traverse guide roller) arranged at a distance in the radial direction from the reel body so as not to interfere with the reel flange. 2. Description of the Related Art Conventionally, a method of winding a wire rod by rotating a reel while moving (traverse) a winding position by moving a guide roller in the reel axial direction is known. However, in this method, since there is a considerable distance between the winding surface on the outer periphery of the reel body and the guide roller, play is possible, and the winding position of the wire rod on the reel body is moved and the reel or guide roller is moved. A shift occurs in the movement, and it is not easy to adjust the traverse at the time of reversing at both ends of the reel body, and the winding surface cannot be controlled. For this reason, even if it is attempted to perform aligned winding by this method, it does not become the intended winding surface, but the wire rods pile up and collapse when a certain amount is piled up, which causes mottle (entanglement). In addition, when this method is used for winding, the winding pitch is large, so the effect of play due to the large distance between the winding surface and the guide roller on the condition of the winding surface is relatively small. Since the wire rods bite between the wires, the wire rods are likely to be scratched, and the winding thickness is increased, creating a space inside, which makes it easy to collapse during loading work. Cause fraying and scratches.

  In addition, if the distance between the winding surface and the guide roller is large in this way, the winding surface can be controlled and aligned winding cannot be performed.Therefore, use a large-diameter disk-shaped guide roller and bring the outer edge of the roller as close as possible to the winding surface. A method of winding the wire is also considered. According to this method, by moving the roller outer edge as close as possible to the winding surface, the movement of the winding position of the wire rod on the reel body and the movement of the reel or the guide roller can be substantially matched. However, in this method, when the wire rod is taken up to the end of the reel flange, there is a possibility that the guide roller may collide with the reel flange portion because the reel flange portion has variations or deformations in processing accuracy. The reel is deformed by being used many times, and the annealing is unavoidable because it is put in the furnace together with the wire. Therefore, it is necessary to adjust the traverse setting every time the winding work is performed so that it does not collide, and it takes time, and if there is a margin in the setting so that it does not collide, As a result, the winding shape becomes far from the aligned winding.

  Also, as a method of winding the wire to the reel flange while bringing the outer edge of the roller close to the winding surface, the guide roller is set to the reel centered on the rotation axis positioned on the outer edge of the roll farther from the outer periphery of the reel body. It is arranged so that it can be tilted in the axial direction, and when the traverse is reversed near the flanges on both ends of the reel body, the axial movement of the reel is stopped, the guide roller is swung, and the outer edge of the roller approaches the reel flange on the reel side. The wire is wound around the flange by the rotation of the reel while tilting in such a manner that, at an intermediate position of the reel body, the guide roller is swung continuously at a constant speed in the axial direction, and the wire is swung around the guide roller. There has been proposed a method of winding around each cycle (for example, see Patent Document 1). According to this method, the guide roller can be tilted at both ends of the reel drum so that the wire can be wound up to the flange and aligned winding is possible. However, with this method, not only when the traverse is reversed, but also at an intermediate position of the reel body, every time the guide roller is swung, the rotation axis of the guide roller is adjusted to the tilt so that the guide roller does not move away from the reel. It is necessary to move it toward or away from the body, which complicates the control. When the guide roller is tilted, for example, if the reel is moving at a constant speed, the traverse pitch changes. Therefore, in order to make the traverse pitch constant, the pitch must be adjusted on the reel side or the guide roller side every time the head is swung, and the control becomes complicated and expensive.

  In addition, the guide roller is disposed so as to be tiltable in the reel axis direction around the rotation axis positioned on the outer edge of the roll farther from the outer periphery of the reel body, and the outer roller edge is located forward of the traverse direction on the side closer to the reel body. It is the same as the above method in that the guide roller is inclined in the direction approaching the reel flange, but the guide roller is inclined at the intermediate position of the reel drum to the opposite side and the guide roller is always inclined except during switching. For example, a method of winding the linear material by rotating the reel while traversing by moving the reel in the axial direction is also considered. According to this method, since the guide roller is traversed while being always inclined, it is not necessary to move the guide roller forward and backward according to the inclination of the guide roller, and the inclination direction of the guide roller is changed during one reciprocation of the traverse. Since it does not change, the control of the pitch adjustment becomes relatively simple. However, also in this case, the guide roller changes its inclination direction every time the traverse is reciprocated. At this time, the guide roller rotates around the rotation center located on the outer edge side of the roll farther from the outer periphery of the reel body. The winding position of the wire material, which is a wound material, on the reel body is slightly shifted in the reel axial direction, and the traverse pitch is changed. Therefore, in order to make the pitch constant, it is necessary to control the reel or the guide roller to move in the reel axial direction, and the control is not easy.

  Therefore, the present applicant also enables the guide roller to be tilted in the reel axial direction so that the roller outer edge is tilted in a direction approaching the reel flange portion in front of the traverse direction on the side close to the reel drum portion. The rotation center for tilting the guide roller is the outer edge side closer to the outer periphery of the reel body, and the guide roller is switched at the middle position of the reel body to traverse the guide roller in an inclined state. Focusing on the method and method, the application was filed earlier (Japanese Patent Application No. 2011-210616). According to this, the winding position does not shift when the tilt direction is switched, and the traverse pitch can be maintained substantially constant.

JP 2001-180866 A

  As described above, in the conventional technique, the distance between the winding surface on the reel and the guide roller is large, and the winding surface cannot be controlled, or the guide roller may collide with the reel flange portion when the traverse is reversed. Alignment winding was not possible, and the wire rod was likely to get tangled or scratched at the flange. Further, in the method of winding the wire rod to the flange while swinging the guide roller, it is necessary to control the guide roller to be close to or away from the reel body each time the head is swung, and the control is complicated and expensive. It was. In the method of always inclining the guide roller and switching the inclination direction at the intermediate position of the traverse, the winding center is set by setting the rotation center for the inclination of the guide roller to the outer edge side closer to the outer periphery of the reel body. Because it is possible to suppress fluctuations in the traverse pitch due to misalignment, the wire rods can be aligned and wound with simple control, but even in this case, depending on the working conditions, the winding position may be shifted due to the tilting of the guide roller . Also in this method, if the reel is deformed by being used many times or deformed by being put in a furnace together with the wire during heat treatment, the guide roller may hit the flange at the flange. .

  It is an object of the present invention to provide a traverse device and a traverse method that can easily, inexpensively and reliably perform aligned winding of wires.

  The traverse device according to the present invention provides a reel that moves a winding position of a wire supplied to a reel via a guide roller having a guide groove on the outer periphery in the reel axial direction along with the movement of at least one of the guide roller and the reel. A traverse device that winds up wire rods in an aligned winding, and at a position away from the reel flange portion, the guide roller is maintained in a posture in which the roller axis is parallel to the reel axis while the outer edge of the roller is reeled in the reel radial direction. Hold at the first position where the distance from the winding surface on the outer periphery of the reel body portion becomes small, entering the inside of the flange portion, and at the position near the reel flange portion, while maintaining the posture that the roller axis is parallel to the reel axis The second outer edge of the roller does not come out of contact with the reel flange portion in the radial direction of the reel. It is obtained by configured to move up location.

  In this traverse device, the wire rod is wound around the reel while moving the winding position of the wire rod relative to the reel at least one of the guide roller and the reel in the axial direction of the reel and moving (traverse) the winding position at an aligned winding pitch. In the process, when the guide roller is at a position away from the reel flange, the outer edge of the roller enters the inside of the reel flange in the radial direction of the reel while maintaining the posture in which the roller axis is parallel to the reel axis. At the position near the reel flange portion, the roller outer edge is in the reel radial direction in the reel radial direction while maintaining the posture that the roller axis is parallel to the reel axis. By moving to the second position where the reel flange portion is not in contact with the reel flange portion. It is possible to reduce the distance between the winding surface on the reel and the guide roller in a wide area in the reel axial direction excluding the part, and to control the winding surface. Even if there is deformation due to repeated use, deformation during wire heat treatment, etc., it is possible to prevent the guide roller from coming into contact with the reel flange, and occurrence of fraying (entanglement) and scratches due to overlapping of the wire Therefore, even with a square wire, an I-shaped wire or other deformed wire, it is possible to perform aligned winding simply, inexpensively and reliably.

  In this traverse device, in particular, the guide roller is maintained in a position in which the roller axis is parallel to the reel axis at a position where the distance between the roller end surface and the reel flange exceeds the first set distance in the reel axis direction. The outer edge of the roller enters the inside of the reel flange portion in the reel radial direction and is held at the first position where the distance from the winding surface on the outer periphery of the reel body is reduced, and the distance between the roller end surface and the reel flange portion is the reel axis direction. In the position where the first distance is not exceeded, the roller axis is gradually moved outward in the radial direction of the reel along with the movement in the reel axial direction while maintaining the posture in which the roller axis is parallel to the reel axis. The outer edge of the roller is at the reel flange portion in the reel radial direction at a position where the distance between the roller and the reel becomes a second distance smaller than the first distance in the reel axis direction. It is preferable to configured to hold a second position not contacting the reel flange portion out to the outside. Thereby, the alignment winding can be easily performed.

  In this traverse device. The first distance is preferably 20 to 40 mm, particularly preferably around 20 mm. The second distance may be 1 to 10 mm. By setting the first distance and the second distance in this way, aligned winding can be performed smoothly and reliably. When the first distance is less than 20 mm, the guide roller moves too rapidly between the first position and the second position, and the wire may be detached from the guide roller. Moreover, if the first distance exceeds 40 mm, the roller outer edge increases in a portion away from the winding surface, and the possibility that the winding position is shifted increases. Further, when the second distance is less than 1 mm, there is a high possibility that the guide roller comes into contact with the reel flange portion when the reel is deformed. However, when there is no deformation of the reel, it is preferable to be close to 0 mm. When the second distance exceeds 10 mm, the state where the outer edge of the roller is away from the winding surface continues for a long time, and there is a possibility that the control of the winding surface at the time of traverse reversal becomes sweet.

  In the traverse apparatus, the first position may be a position where the distance between the outer edge of the roller and the winding surface of the outer periphery of the reel body exceeds 0 mm and is 30 mm or less. By doing so, the winding position can be accurately controlled in a wide area in the reel axial direction, and aligned winding can be performed as intended. If the distance between the roller outer edge and the winding surface on the outer periphery of the reel body exceeds 30 mm, the winding position may not be accurately controlled. It is better to make this distance as small as possible so as not to hit the winding surface.

  In this traverse device, the width dimension of the guide groove of the guide roller is preferably the width dimension of the wire +0.1 to 0.50 mm. By making the guide groove with such a width dimension, it is possible to prevent deviation of the wire rod while ensuring play in the width direction of the groove, and to accurately control the winding position and align the winding as intended. It can be performed. If the width dimension of the guide groove is less than the width dimension of the wire + 0.1 mm, there is less play, the wire is not smoothly drawn out, and scratches may occur. If the width of the guide groove exceeds the width of the wire +0.50 mm, the wire may be displaced in the width direction of the guide groove and the winding position may not be accurately controlled.

  Further, the traverse method of the present invention uses the traverse device having the above-described configuration, and at the position away from the reel flange portion, the guide roller is maintained in a posture in which the roller axis is parallel to the reel axis, and the outer edge of the roller is the reel. Position that enters the inside of the reel flange portion in the radial direction and is held at the first position where the distance from the winding surface on the outer periphery of the reel body is reduced, and the roller axis is parallel to the reel axis at the position near the reel flange portion The roller outer edge moves outside the reel flange portion in the reel radial direction and is moved to the second position where it does not interfere with the reel flange portion. By this method, aligned winding can be performed easily, inexpensively and reliably.

  As is apparent from the above description, according to the present invention, the distance between the winding surface on the reel and the guide roller can be reduced in a wide area in the reel axial direction excluding the reel flange portion. It is possible to control the guide roller so that it does not come into contact with the reel flange even if the reel flange has variations in processing accuracy, deformation due to repeated use, or deformation during heat treatment of the wire. Therefore, it is possible to prevent the occurrence of fraying (entanglement) and scratches due to the overlapping of the wire rods, and even straight wires, I-shaped wire rods and other irregular wires can be simply, inexpensively and reliably aligned.

It is a top view which shows the principal part of the traverse apparatus of embodiment of this invention. It is a side view which shows the principal part of the traverse apparatus of embodiment of this invention. It is a schematic diagram explaining operation | movement of the guide roller in the traverse apparatus of embodiment of this invention. It is sectional drawing which expands and shows the part of the guide groove of the guide roller outer periphery in the traverse apparatus of embodiment of this invention.

  1 and 2 show the main configuration of the traverse apparatus according to the embodiment of the present invention. In the figure, 1 is a reel (take-up reel), 1a is a reel barrel, 1b is a reel flange, 2 is a guide roller (traverse guide roller), 2a is a guide groove on the outer periphery of the guide roller, and 3 is a guide roller. A support arm 4 is a support block that supports the support arm 3.

  The guide roller 2 has a roller outer edge disposed between the reel flange portions 1b on both sides of the reel 1 so as to face the outer periphery of the reel drum portion 1a, and rotates via a bearing 6 on a roller shaft 5 supported by the support arm 3. It is supported freely.

  The support arm 3 is supported by the support block 4, and the support position of the support arm 3 can be moved forward and backward toward the reel axis R with respect to the support block 4 by operating the adjustment handle 12.

  The support block 4 is perpendicular to the reel axial direction using a horizontal moving air cylinder (not shown) as a drive source on a linear guide rail (not shown) installed on a base (not shown). It is mounted on a movable table 11 that is movable in a direction (a direction that moves forward and backward with respect to the reel body 1a). The support block 4 is movable in this way, and the guide block 2 moves on the reel 1 side at the outer edge of the guide roller 2 by moving the support block 4 together with the moving base 11 in a direction to advance and retreat with respect to the reel barrel 1a. It moves in the direction approaching or leaving the reel radial direction with respect to 1a. Further, the support block 4 is rotatable on the moving table 11 around the center of curvature of the R guide 8 along the R guide (arc-shaped guide rail) 8 with the air cylinder 9 as a drive source.

  In this traverse device, the reel 1 is moved in the reel axial direction (vertical direction in FIG. 1), whereby the winding position of the wire T supplied through the guide roller 2 with respect to the reel 1 is set at the pitch of the aligned winding. The reel 1 is rotated while moving (traverse) in the direction so that the wire rod T is wound around the reel body 1a, and each time the linear material T is wound up by one layer, the moving base 11 is moved to move the guide roller 2 Is moved in a direction away from the reel body 1a by the thickness of one layer of the wire material T, and the wire material T is wound up by reversing the traverse direction. In the traverse process, the guide roller 2 is moved away from the reel flange portion 1b (in the reel axial direction) so that the outer edge of the roller greatly enters the inside of the reel flange portion 1b in the reel radial direction. The position (D shown in FIG. 3) with the outer peripheral winding surface of the part 1a is held at a position (position in the reel radial direction) in the range of more than 0 mm and not more than 30 mm (position in the reel radial direction). ), The guide roller 2 is directed from the first position to the outside in the reel radial direction as the reel 1 moves in the reel axial direction, and the outer edge of the roller is outward from the reel flange portion 1b in the reel radial direction. When the distance between the outer edge of the reel flange portion 1b and the outer edge of the reel flange portion 1b (C shown in FIG. 3) exceeds 0 mm and is 20 mm or less, Not contact with di portion 1b position to (Lille radial position) is gradually moved at a predetermined speed. When the traverse reversal position is reached, it is gradually moved in the reverse direction. In the meantime, the guide roller 2 is maintained throughout and the posture in which the roller axis K is parallel to the reel axis T is maintained.

  A more detailed operation of the guide roller 2 will now be described with reference to FIG. FIG. 3 schematically shows the operation of the guide roller. In this embodiment, when the reel 1 moves, the guide roller 2 moves relative to the reel 1 in the reel axial direction, and the guide roller 2 does not move in the reel axial direction. In FIG. 3, the relative movement is indicated by the movement of the guide roller 2 for the convenience of explanation.

  As the reel 1 moves, the guide roller 2 moves relative to the reel 1 in the reel axial direction as shown in FIG. Then, a position where the distance between the roller end surface 2b and the reel flange portion 1b, which is far from the reel flange portion 1b, exceeds 20 to 40 mm (first distance) in the reel axial direction (from a position corresponding to the distance A in FIG. 3). At the inner position in the reel axis direction), the guide roller 2 keeps the posture in which the roller axis K is parallel to the reel axis R, and the outer edge of the roller greatly enters the inner side of the reel flange portion 1b in the reel radial direction. The distance (D shown in FIG. 3) with the outer peripheral winding surface of the part 1a is held at a position (position in the reel radial direction) in a range exceeding 0 mm and 30 mm or less, and the wire T is wound up in that state.

  Then, the guide roller 2 approaches the reel flange portion 1b and reaches a position where the distance between the roller end surface 2b and the reel flange portion 1b is 20 to 40 mm (first distance) (position where the distance A is shown in FIG. 3). Then, the guide roller 2 is moved toward the outside in the reel radial direction at a predetermined speed, and the distance between the roller end surface 2b and the reel flange portion 1b is 1 to 10 mm in the reel axial direction smaller than the first distance (20 to 40 mm). The wire rod is gradually moved along with the movement in the reel axis direction while maintaining the posture in which the roller axis is parallel to the reel axis until reaching the second distance (position B in FIG. 3). T is rolled up.

  When the distance between the roller end surface and the reel flange portion 1b reaches the position (position where the distance B in FIG. 3) is the second distance (1 to 10 mm), the outer edge of the roller becomes the reel flange portion in the reel radial direction. The distance from the reel flange portion 1b shown by C in FIG. 3 to the outside of 1a becomes a distance in the range of more than 0 mm and 20 mm or less between the guide roller 2 and the reel flange portion 1b. It is held at the second position (position in the reel radial direction) where it does not occur.

  Then, the guide roller 2 exceeds the position where the distance between the roller end surface 2b and the reel flange portion 1b becomes the second distance (1 to 10 mm) (position where the distance B in FIG. When the position indicated by E in FIG. 3 which is the guide roller turn position) is reached, the guide roller 2 is temporarily stopped, and then the moving direction in the reel axial direction is reversed. And after reversal, it moves gradually from the 2nd position toward the 1st position, and winds wire T in the opposite direction.

  By such an operation of the guide roller 2, the distance between the winding surface on the reel 1 and the guide roller 2 can be reduced in a wide area in the reel axial direction excluding the reel flange portion 1 b, and the winding surface can be accurately set. The guide roller 2 does not come into contact with the reel flange portion 1b even if the reel flange portion 1b has variations in processing accuracy, deformation due to repeated use, deformation during wire heat treatment, etc. As a result, it is possible to prevent the occurrence of fraying (entanglement) and scratches due to the overlapping of the wire rods T, and it is possible to perform aligned winding simply, inexpensively and reliably.

  The traverse device of this embodiment is suitable for aligning and winding metal wires such as steel cords, bead wires, and piston ring wires, covered wires such as electric wires, and other wire materials such as ropes. Even I-shaped wire rods and other deformed wires can be simply, inexpensively and reliably aligned and wound.

  The width dimension (a shown in FIG. 4) of the guide groove 2a of the guide roller 2 is preferably 0.1 to 0.50 mm larger than the width dimension (W shown in FIG. 4) of the wire T. By making the guide groove 2a of such a width dimension, it is possible to prevent deviation of the wire T while ensuring play (t shown in FIG. 4) in the width direction of the groove, and to accurately set the winding position. It is possible to perform the aligned winding as intended by controlling to.

  In the above embodiment, the case where the reel 1 is moved and traversed has been described. However, the guide roller 2 may be moved in the reel axial direction without moving the reel 1, and the reel 1 and the guide roller 2 may be moved. Both may be moved and traversed.
