JP 2005-519827 Gazette

 However, in the process of winding the wire around the reel, among the plurality of wires wound around the reel, the winding form of the wire located at the end in the reel axial direction is easily broken, and the reel includes the wound wire May be smaller at the end in the reel axial direction than at the center in the reel axial direction. In this case, among the plurality of wires transferred toward the reel, the wire located at the end in the reel axial direction may be loosened and entangled with the comb teeth portion.

  The present invention has been made in consideration of such circumstances, and among the plurality of wires transferred toward the reel, the wire positioned at the end in the reel axial direction is loosened and entangled with the comb teeth portion. It is an object of the present invention to provide a reel winding device and a reel winding method that can prevent the above.

  In order to solve the above-described problems and achieve such an object, the reel winding device of the present invention is a reel that is rotated around the reel axis in a state where a plurality of wires are arranged in the reel axis direction. A reel take-up device that winds the reel toward the reel, and has a plurality of comb teeth arranged at intervals in the reel axial direction, and is arranged upstream of the reel in the wire transfer direction. In addition, a comb tooth portion configured to allow a plurality of wire rods to pass between a pair of adjacent comb teeth in the reel axial direction is provided, and a plurality of wire teeth are provided between the comb tooth portion and the reel. A pair of rollers that sandwich at least wire rods positioned at both ends in the reel axial direction among the wire rods in a direction intersecting the transfer direction in a side view of the apparatus as viewed from the reel axial direction are disposed, and of these rollers Less One and also is characterized by being rotatable.

  Further, the reel winding method of the present invention is a reel winding method in which a plurality of wire rods are transferred to a reel rotated around the reel axis in a state of being arranged in the reel axis direction, thereby winding the reel around the reel. The reel winding device according to the present invention is used to sandwich at least one of the plurality of wire rods positioned at both ends in the reel axial direction between the pair of rollers and to drive at least one of these rollers in rotation. By doing so, the transfer speed of the wire from the pair of rollers to the reel is increased.

  In this invention, a wire rod positioned at least at both ends in the reel axial direction among a plurality of wire rods is sandwiched between the pair of rollers, and at least one of these rollers is rotationally driven, whereby the reel from the pair of rollers is rotated. In the process of winding a plurality of wires around a reel, the winding form of the wire located at the end in the reel axial direction among the plurality of wires wound around the reel is increased. The outer diameter of the reel including the wound and wound wire rod is smaller at the end in the reel axial direction than at the central portion in the reel axial direction, so that a plurality of reels positioned between the reel and the comb tooth portion Even if the wire located at the end of the reel in the axial direction of the wire is loosened and tries to get entangled with the comb tooth portion, the slack can be reduced by increasing the winding amount of the wire to the reel per unit time. It is possible to obtain, the wire can be prevented from becoming entangled with the comb tooth.

Here, an elastically deformable protrusion is projected on the outer peripheral surface of one of the pair of rollers, and the wire intersects the transport direction by the protrusion and the outer peripheral surface of the other roller. It may be sandwiched in the direction to do.
In this case, since the protrusions are provided on the outer peripheral surface of at least one of the pair of rollers that are driven to rotate, the outer periphery of the roller is damaged, for example, by sandwiching the wire rod with the rollers as described above. Or the pinched wire can be prevented from being easily broken.
Further, when the wire rod is sandwiched between the pair of rollers as described above, the protrusion is pressed against the outer peripheral surface of the wire rod and the other roller, and is bent in an elastic state upstream in the transfer direction. At the moment of separating from the outer peripheral surface of the roller, it is possible to apply an elastic restoring force toward the downstream side in the transfer direction of the protrusion on the wire, and it is possible to reliably increase the transfer speed of the wire. .

Further, a slack detecting means for detecting slack of the wire rod is provided between the comb tooth portion and the reel, and at least one of the pair of rollers is based on a detection signal from the slack detecting means. A control unit that controls rotation may be provided.
In this case, for example, at least one of the pair of rollers is not driven to rotate when the winding form of the wire to the reel is uniform over the entire length in the reel axial direction, and the wire is loosened as described above. It is possible to increase the winding amount per unit time of the wire rod around the reel by rotating only at times.
Alternatively, for example, at least one of the pair of rollers is different from the case where the winding form of the wire rod on the reel is uniform over the entire length in the reel axial direction and when the wire rod is loosened as described above. Regardless of whether the wire rod is always rotated and the wire rod is slack as described above, the amount of winding of the wire rod onto the reel is increased by increasing the rotation speed of at least one of the pair of rollers. It is also possible to make it.

Further, the comb tooth portion and the pair of rollers are provided so as to be reciprocally movable in the reel axial direction, and are located on the stroke center side when the moving speed is located on the stroke end side of the reciprocating movement. It may be later than usual.
In this case, it is possible to suppress the outer diameter of the reel including the wound wire from being smaller at the end in the reel axial direction than at the central portion in the reel axial direction.

  According to the present invention, in the process of transferring a plurality of wires to the reel, it is possible to prevent the wires located at the ends in the reel axial direction from being loosened and entangled with the comb teeth.

The reel winding device 10 includes a rotation driving unit (not shown) that rotates the reel 11 around the reel axis O, and a comb tooth portion 12 that is disposed on the upstream side in the transfer direction A of the wire W from the reel 11. ing. The comb teeth portion 12 has a plurality of comb teeth 12a arranged at intervals in the reel axis O direction.
As described above, a plurality of wire rods W are transferred toward the reel 11 rotated around the reel axis O in a state of being arranged in the reel axis O direction, and the pair of comb teeth 12a adjacent in the reel axis O direction are adjacent to each other. It is configured to be wound around the reel 11 after passing between each other.

  In this embodiment, between the comb tooth portion 12 and the reel 11, the wire 10 positioned at least at both ends in the reel axis O direction among the plurality of wires W is viewed from the reel axis O direction. A pair of rollers 13 and 14 sandwiched in a direction crossing the transfer direction A in the side view is disposed, and at least one of these rollers 13 and 14 is rotatably provided. In the illustrated example, of the pair of rollers 13 and 14, a roller (hereinafter referred to as a driving roller) 13 disposed on the upper side is provided so as to be rotatable around its axis by a driving means (not illustrated) and disposed on the lower side. A roller (hereinafter referred to as a free roller) 14 is provided so as to be rotatable about its axis.

  Furthermore, in the present embodiment, an elastically deformable protrusion 15 formed of, for example, a synthetic resin or a rubber-like elastic body is provided on the outer peripheral surface of the driving roller 13. The wire W being transferred is sandwiched between the protrusion 15 and the outer peripheral surface of the free roller 14. In the illustrated example, when the protrusion 15 sandwiches the wire W with the outer peripheral surface of the free roller 14, the tip thereof is bent in an elastic state toward the upstream side in the transfer direction A. It is configured. The protrusion 15 extends over the entire length of the drive roller 13 in the axial direction, and a plurality of the protrusions 15 are provided at intervals in the circumferential direction.

In the present embodiment, the slack detecting means 16 for detecting slack of the wire W being transferred is provided between the comb tooth portion 12 and the reel 11. In the illustrated example, the slack detecting means 16 is a wire rod positioned at both ends in the reel axis O direction among the plurality of wire rods W transferred between the comb tooth portion 12 and the pair of rollers 13 and 14. It is arranged separately under W. Furthermore, in the present embodiment, a control unit 17 that controls the rotation of the drive roller 13 based on a detection signal from the slack detection means 16 is provided.
Further, the comb tooth portion 12 and the pair of rollers 13 and 14 are provided so as to be reciprocally movable in the reel axis O direction, and when the moving speed is located on the stroke end side of the reciprocating movement, the comb tooth portion 12 and the pair of rollers 13 and 14 are located on the stroke center side. It is slower than when you are.

 In the reel winding device 10 configured as described above, in the process of transferring a plurality of wires W toward the reel 11 rotating around the reel axis O in a state of being arranged in the reel axis O direction, The wire W first reaches the comb tooth portion 12 and passes through a pair of adjacent comb teeth 12a in the reel axis O direction to be aligned in the reel axis O direction. The wire W is sandwiched between the drive roller 13 and the free roller 14 that are rotationally driven, so that the transfer speed in the transfer direction A is increased.

 That is, the protrusion 15 protruding from the driving roller 13 is pressed against the outer peripheral surface of the wire W and the free roller 14 and is bent in an elastic state upstream in the transfer direction A. At the moment of separating from the outer peripheral surface of the free roller 14, an elastic restoring force toward the downstream side in the transfer direction A of the protrusion 15 is applied to the wire W, so that the transfer speed of the wire W is increased.

The drive roller 13 is driven to rotate so that the peripheral speed at the tip of the protrusion 15 is greater than the transfer speed of the wire W on the upstream side in the transfer direction A than the pair of rollers 13 and 14.
Further, in the process of winding the plurality of wires W around the reel 11 as described above, the comb tooth portion 12 and the pair of rollers 13 and 14 are reciprocated in the reel axis O direction. The moving speed at this time is slower when the comb tooth portion 12 and the pair of rollers 13 and 14 are located at the stroke end side of the reciprocating movement than when they are located at the stroke center side.

 As described above, according to the reel winding device 10 according to the present embodiment, the drive roller 13 and the free roller that are driven to rotate the wire W positioned at least at both ends in the reel axis O direction among the plurality of wires W. 14, the transfer speed of the wire W from the rollers 13 and 14 to the reel 11 is made faster than the transfer speed from the comb tooth portion 12 to the pair of rollers 13 and 14, so that a plurality of wires In the process of winding W on the reel 11, the winding form of the wire W positioned at the end in the reel axis O direction among the plurality of wires W wound on the reel 11 is broken, and the wound wire W is wound. The reel 11 including the outer diameter of the reel 11 becomes smaller at the end in the reel axis O direction than at the center in the reel axis O direction, so that the plurality of wires W positioned between the reel 11 and the comb tooth portion 12 U Even if the wire W positioned at the end in the reel axis O direction is loosened and tries to get entangled with the comb tooth portion 12, the looseness is suppressed by increasing the amount of winding of the wire W around the reel 11 per unit time. It becomes possible to prevent the wire W from being entangled with the comb teeth portion 12.

Further, in the present embodiment, since the protrusion 15 protrudes from the outer peripheral surface of the drive roller 13, by sandwiching the wire W between the drive roller 13 and the free roller 14 as described above, for example, the rollers 13, 14 It is possible to prevent the outer peripheral portion of the wire from being damaged or the pinched wire W from being easily broken.
Further, when the wire W is sandwiched between the drive roller 13 and the free roller 14 as described above, the protrusion 15 is pressed against the outer peripheral surface of the wire W and the free roller 14 and bent in an elastic state upstream in the transfer direction A. The elastic restoring force of the protrusion 15 toward the downstream side in the transfer direction A can be applied to the wire W at the moment when the protrusion 15 is separated from the outer peripheral surfaces of the wire W and the free roller 14. Thus, the transfer speed of the wire W can be reliably increased.

In the present embodiment, the slack detection means 16 is provided between the comb tooth portion 12 and the reel 11, and the control section controls the rotation of the driving roller 13 based on the detection signal from the slack detection means 16. 17 is provided, for example, the drive roller 13 is not driven to rotate when the winding form of the wire W around the reel 11 is uniform over the entire length in the reel axis O direction, and the wire W is as described above. It is possible to increase the amount of winding of the wire W onto the reel 11 per unit time only when it is loosened.
Instead of this, for example, the driving roller 13 is different when the winding form of the wire W around the reel 11 is uniform over the entire length in the reel axis O direction and when the wire W is slackened as described above. Regardless of whether the wire W is slack as described above, the rotational speed of the drive roller 13 is increased, thereby increasing the amount of winding of the wire W around the reel 11 per unit time. It is also possible to do so.

 Further, in the present embodiment, when the comb tooth portion 12 and the pair of rollers 13 and 14 are provided so as to be able to reciprocate in the direction of the reel axis O, and the moving speed is located on the stroke end side of the reciprocating movement. Since the reel 11 including the wound wire rod W is configured so that the outer diameter of the reel 11 including the wound wire rod W is closer to the end in the reel axis O direction than the center portion in the reel axis O direction. It is possible to suppress the reduction in the part.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, in the above-described embodiment, the protrusions 15 are provided on the outer peripheral surface of the drive roller 13 so as to extend over the entire length in the axial direction. If each wire W is sandwiched between the protrusion 15 and the outer peripheral surface of the free roller 14, the protrusion 15 may be provided limited to both ends in the axial direction on the outer peripheral surface of the drive roller 13, for example. Alternatively, it may be intermittently scattered in the reel axis O direction.

Furthermore, although the slackness detecting means 16 and the control unit 17 are provided in the embodiment, the slackness detecting means 16 and the control part 17 may not be provided.
