  Hereinafter, the wire supply device 10 according to the embodiment will be described (see FIGS. 1 and 2). The wire supply device 10 is a device that supplies the wire 12 from a plurality of wire winding bodies 20.

  For convenience of explanation, the wire 12 and the wire wound body 20 will be described. The wire 12 is a conductor strand, for example. In this case, the wire supply device 10 is used when supplying a conductor wire to a wire drawing device. In addition, examples of the wire 12 include a covered electric wire and other wire members, and the wire supply device can be used for supplying the wire 12 to a twisted wire device and a coating device.

  The wire 12 is supplied from a wire wound body 20. More specifically, the wire 12 is wound in a form in which the winding end of the first wire rod wound body 20 and the winding start of the second wire rod wound body 20 are continuous. The wire wound body 20 includes a column part 22, a pair of flange parts 24, and a wire 12 in a wound form. The column portion 22 is a portion around which the wire 12 is wound around the outer peripheral portion, and is formed in a columnar shape. The pair of flange portions 24 are portions that restrict the wire 12 wound around the column portion 22 from coming off in the central axis direction of the column portion 22. The pair of flange portions 24 are formed in a shape projecting to the outer peripheral side of the column portion 22 at both ends in the central axis direction of the column portion 22. Here, as for a pair of collar part 24, the outer peripheral part is formed in circular shape. And the wire 12 wound around the outer peripheral part of the pillar part 22 is accommodated between a pair of collar parts 24. FIG.

For example, the wire wound body may be configured such that the wire 12 is wound and accommodated in a column or a pair of flanges formed in a polygonal column shape or a polygonal plate shape, or the column portion and its center. The structure provided with the collar part in which the wire 12 wound only to one axial direction was mounted may be sufficient. Moreover, the wire winding body may be comprised only by winding the wire 12, and the wire 12 may be wound and accommodated in the donut-shaped container by which upper direction was open | released.

<Wire supply device>
The wire supply device 10 includes the above-described plurality of wire winding bodies 20, a support portion 30, a drawing guide portion 40, a support pillar portion 50, and a wire rod restriction portion 60.

  Here, the wire supply apparatus 10 which supplies the wire 12 from the two wire winding bodies 20 is demonstrated to an example. That is, the wire rod has a form in which the winding end of the first wire rod wound body 20 (right side in FIGS. 1 to 5) and the winding start of the second wire rod wound body 20 (left side in FIGS. 1 to 5) are continuous. 12 is wound and stored. And after drawing out the wire 12 from the 1st wire winding body 20, it is comprised so that it may pull out from the 2nd wire winding body 20 continuously.

  The first and second wire winding bodies 20 are inclined around the base shaft 15 in a posture in which the central axis when the wire 12 is wound is inclined with respect to a plane perpendicular to the predetermined base shaft 15. It is arranged. Here, the first and second wire rod wound bodies 20 are arranged with the central axis along the base axis 15. Moreover, the 1st and 2nd wire winding body 20 is supported by the support part 30 so that replacement | exchange is possible. That is, the support portion 30 is configured to be able to support the two wire rod wound bodies 20. More specifically, the support part 30 supports the two wire rod wound bodies 20 at positions where their respective central axes are substantially equidistant from the base axis 15 in plan view. Moreover, it is good for the support part 30 to be comprised so that the wire wound body 20 may be mounted in the mounting shape so that relative movement is impossible in the direction orthogonal to the central axis. For example, the support part 30 is good to be comprised so that it may support with the uneven | corrugated fitting state with respect to the wire winding body 20 so that attachment or detachment is possible. And if all the wire 12 wound and accommodated in the wire winding body 20 is pulled out, the wire winding body 20 supported by the support part 30 is replaced | exchanged, and the new wire 12 can be supplied.

  The drawing guide part 40 is a wire winding in which the wire 12 in the first or second wire wound body 20 is drawn out from the wire 12 wound and accommodated in the wire wound body 20 supported by the support part 30. This is a part that guides the body 20 to be pulled out along a route corresponding to the position of the body 20. The drawer guiding portion 40 includes a main body portion 41, a guiding portion 42, and a drawer portion 46. More specifically, the drawer guiding portion 40 is configured such that a guiding portion 42 is provided at a distal end portion of a main body portion 41 formed in a long plate shape, and a leading portion 46 is provided at a proximal end portion. Yes. And the drawer | guidance | derivation guide part 40 is comprised so that a movement to the position of each upper direction of the 1st and 2nd wire rod winding body 20 with which the guide part 42 was supported by the support part 30 by own rotation operation | movement is carried out.

  The drawer guiding portion 40 is supported around the base shaft 15 so as to be capable of rotating. In the following description, the base shaft 15 may be referred to as the rotation shaft of the drawer guiding portion 40. More specifically, the drawer guiding portion 40 is supported by the support column portion 50. The support column part 50 is a columnar part erected along the central axis direction of the wire wound body 20 supported by the support part 30. With this support column part 50, the drawing guide part 40 is supported at a position above the wire wound body 20 supported by the support part 30. Here, the drawer guiding portion 40 is supported in a manner that is flat along the vertical direction and elongated in the horizontal direction, and the base end portion is supported so as to be relatively rotatable around the rotation axis with respect to the support column portion 50. . In other words, the drawer guiding portion 40 has a distal end portion (outer peripheral portion) capable of moving a relatively long distance around the rotation axis by a rotation operation, and a proximal end portion (inner peripheral portion) at a substantially constant position with a smaller movement amount. Maintained.

  The guiding portion 42 is a portion that is provided on the outer peripheral side portion of the drawing guiding portion 40 and supports the wire 12 drawn from the wire winding body 20 so as to be movable in the extending direction. In addition, the drawing portion 46 is a portion that is provided on the inner peripheral side portion of the drawing guiding portion 40 and from which the wire 12 supported by the guiding portion 42 is drawn. Here, each of the guide portion 42 and the lead-out portion 46 is configured by a pulley that is supported so as to be rotatable relative to the long plate-like main body portion 41. More specifically, the guide portion 42 and the drawer portion 46 are supported so as to be rotatable around a parallel axis along the horizontal direction with respect to the main body portion 41. Then, the wire 12 is hung on the groove bottoms of the guide part 42 and the lead-out part 46 along a path passing through the upper side of the guide part 42 and the lower side of the lead-out part 46, and is drawn upward.

  In addition, the drawing guide unit 40 guides the wire 12 passed from the guiding unit 42 toward the drawing unit 46 to a horizontal path (here, a horizontal path) that is directed downward from the guiding unit 42. They are arranged in a possible positional relationship. In other words, in the height direction, the drawer guiding portion 40 is disposed at a position where the upper end of the groove bottom of the guiding portion 42 and the lower end of the groove bottom of the leading portion 46 are spaced from each other by the diameter of the wire 12. Good.

  Further, the drawing guide part 40 is rotatably supported so that the guide part 42 moves on a track including immediately above the central axis of each of the first and second wire winding bodies 20 supported by the support part 30. Has been. In other words, the guide part 42 can be moved to a position immediately above the central axis of each wire wound body 20 supported by the support part 30 by the rotation operation of the drawing guide part 40 (see FIGS. 2 and 5). . That is, when the wire guide 12 can be pulled out from a position immediately above the central axis of the wire wound body 20 from which the wire 12 is pulled out and is pulled out from the wire 12 from a different wire wound body 20. Also, the wire 12 can be pulled out from a position immediately above the central axis of the wire wound body 20.

  When the wire rod 12 wound and accommodated in the first wire rod wound body 20 is all drawn out and the drawn wire rod 12 is transferred to the second wire rod wound body 20, the wire rod regulating unit 60 This is the part that regulates the route. More specifically, the wire rod restricting portion 60 is configured to be able to guide the wire rod 12 to the outer peripheral side with respect to the rotation axis of the drawing guide portion 40. That is, the wire 12 extending between the first wire rod wound body 20 and the second wire rod wound body 20 is located on the outer peripheral side with respect to the rotation axis of the drawing guide portion 40 with respect to the wire rod regulating portion 60. Arranged through. And the wire rod control part 60 makes the rotation operation | movement of the drawer | drawing-out guidance part 40 smooth with the transfer of the wire 12, by moving the wire 12 through the outer peripheral side more.

  The wire rod regulating unit 60 is erected between the first and second wire wound bodies 20 supported by the support unit 30. The wire rod regulating unit 60 is erected between the first wire rod wound body 20 and the second wire rod wound body 20, and the first wire rod wound body 20 and the second wire rod wound body 20 The wire 12 extending between the two is configured so as to be restricted in a direction away from the base shaft 15. Here, the wire rod restricting portion 60 is formed in a shape having a cylindrical peripheral surface (here, a cylindrical shape along the central axis of the base shaft 15). In addition, here, the wire rod regulating portion 60 is in an intermediate region between the first wire rod wound body 20 and the second wire rod wound body 20 (region between the support portions 30 separated in FIG. 1). It is erected at a position directly below the track of the guide portion 42 of the drawer guide portion 40. More preferably, the wire rod regulating portion 60 is provided at a position intermediate between the two wire rod wound bodies 20 in the direction connecting the two wire rod wound bodies 20. Further, the wire rod restricting portion 60 is set to a height dimension lower than the guiding portion 42 of the drawing guiding portion 40. More preferably, the height dimension of the wire rod restricting portion 60 may be set as high as possible within a range in which the wire rod 12 supported by the guide portion 42 is not caught when the drawer guiding portion 40 rotates.

<Operation of wire supply device>
Next, operation | movement of the wire supply apparatus 10 is demonstrated. As an initial state, in the wire supply device 10, the two wire rod wound bodies 20 in which the continuous wire rods 12 are wound and accommodated are supported by the support portion 30, and the wire rods 12 are drawn from the first wire rod wound bodies 20. It is in a state where it is hung on the guiding portion 42 and the pulling portion 46 of the pulling guiding portion 40 and pulled upward (see FIG. 2). In addition, it is assumed that the drawing guide portion 40 is located at a position between the two wire rod wound bodies 20 in a direction connecting the two wire rod wound bodies 20 in a plan view.

  When the supply of the wire 12 is started, the wire 12 is drawn out above the drawing portion 46 (see FIG. 3). As a result, the lead-in guide portion 40 is pulled by the wire rod 12, and the guide portion 42 is positioned above the first wire rod wound body 20 from which the wire rod 12 is drawn out (more specifically, immediately above the central axis). Rotate to move. In this state, the wire 12 is pulled out from the first wire wound body 20.

  When all of the wire 12 wound and accommodated in the first wire wound body 20 is pulled out, it is pulled by the wire 12 continuously wound and accommodated in the second wire wound body 20 and is drawn out. 40 rotates to the 2nd wire wound body 20 side (refer FIG. 4). At this time, the wire 12 passing through the outer peripheral side of the wire restricting portion 60 comes into contact with the wire restricting portion 60 and is restricted from moving toward the inner periphery. For this reason, a larger force acts in the circumferential direction on the guide portion 42 provided on the outer peripheral side portion of the lead guide portion 40 pulled by the wire rod 12 passing through the outer peripheral side of the wire rod regulating portion 60. That is, when the wire 12 is not restricted by the wire restricting portion 60, the force acting on the guiding portion 42 is large because the force acting on the guiding portion 42 is large because the wire 12 passes through the position on the inner peripheral side. Tend to be smaller. Thereby, the drawer | drawing-out guide part 40 is rotated more smoothly from the 1st wire wound body 20 to the 2nd wire rod wound body 20 side.

  The wire wound body 20 is pulled by the wire 12, and the guide portion 42 is positioned above the second wire wound body 20 from which the wire 12 is drawn (more specifically, directly above the central axis). It rotates so as to move (see FIG. 5). In this state, the wire 12 is pulled out from the second wire wound body 20.

  As described above, the wire 12 is supplied from the wire supply device 10. When all the wire 12 is pulled out from the second wire wound body 20, it is preferable to replace the wire wound body 20 and supply a new wire 12. Further, the first wire wound body 20 is exchanged during the drawing of the wire 12 wound and accommodated in the second wire wound body 20 and connected to the end of winding of the second wire wound body 20. Thus, the wire rod may be pulled out from the first wire rod wound body 20 that is continuously replaced after the wire rod 12 is pulled out from the second wire rod wound body 20.

  According to the wire rod supply apparatus 10 according to the above embodiment, the first or the wire rod 12 in which the winding end of the first wire rod winding body 20 and the winding start of the second wire rod winding body 20 are continuous is wound or stored. The second wire rod wound body 20 is disposed around the predetermined base shaft 15 with a central axis along which the wire rod 12 is wound along the predetermined base shaft 15 being spaced around the predetermined base shaft 15. The guide part 40 that is supported so as to be able to rotate is provided on the outer peripheral side part and supports the wire 12 drawn out from the first or second wire wound body 20 so as to be movable in the extending direction. 42, and a lead-out portion 46 from which the wire 12 supported by the guide portion 42 is drawn out and provided on the inner peripheral side portion, and the guide portion 42 is rotated by each of the first and second wire wound bodies 20. It is comprised so that a movement to the position above is possible. Thereby, when all the wire 12 wound and accommodated in the first wire wound body 20 is drawn out and the wire 12 wound and accommodated in the second wire wound body 20 is started to be pulled out, the guiding portion 42 is provided. Is moved from the first wire rod wound body 20 onto the second wire rod wound body 20 by the movement of the drawing position of the wire rod 12, and the drawing guiding portion 40 is rotated. In this way, the second wire winding from the position where the drawing guide portion 40 rotates and the wire 12 can be easily pulled out from the first wire winding 20 with the operation of changing the wire winding 20 from which the wire 12 is pulled out. The support position of the guide portion 42 is changed to a position where the wire 12 can be easily pulled out from the body 20. For this reason, the support position of the wire 12 is changed by the force that the wire 12 moves without setting the timing of the drawing mode of the wire 12 that can change every time, and the wire 12 can be supplied more smoothly.

  Further, the drawer guiding portion 40 is rotatably supported so that the guiding portion 42 moves on a track including the portion directly above the central axis of the first or second wire wound body 20. For this reason, the wire 12 wound and accommodated in the wire wound body 20 is drawn out while moving around the central axis directly above the central axis of the first or second wire wound body 20, and the supply of the wire 12 Can be done more smoothly.

  In addition, the drawing guide section 40 is arranged in such a positional relationship that the guiding section 42 and the drawing section 46 can guide the wire 12 passed from the guiding section 42 toward the drawing section 46 in a horizontal or downward path. Has been. For this reason, the height dimension of the whole apparatus can be made smaller.

  Moreover, it stands up between the 1st wire rod wound body 20 and the 2nd wire rod wound body 20, and is extended between the 1st wire rod wound body 20 and the 2nd wire rod wound body 20. When the wire 12 moves from the first wire rod wound body 20 to the second wire rod wound body 20, the wire rod 12 further includes a wire rod restricting portion 60 that can be regulated in a direction away from the predetermined base shaft 15. It is guided so as to pass through the outer periphery side of the drawer guiding part 40, and the rotation of the drawer guiding part 40 can be made smoother.

  In addition, the wire rod regulating portion 60 is erected at a position directly below the track of the guide portion 42 of the drawing guide portion 40 in an intermediate region between the first wire rod wound body 20 and the second wire rod wound body 20. Therefore, the guiding part 42 can be moved more closely according to the transition timing of the wire 12, and the drawing guiding part 40 can be rotated more smoothly.

  Moreover, since the wire rod restricting portion 60 is formed in a shape having a cylindrical peripheral surface, the operation of the wire rod 12 in contact with the wire rod restricting portion 60 can be made smooth.

  So far, although the wire supply apparatus 10 provided with two wire winding bodies 20 has been described, three or more wire winding bodies 20 may be provided. For example, when three wire winding bodies are provided, the winding end of the first wire winding body and the winding start of the second wire winding body of the wire 12 and the winding end of the second wire winding body are completed. And the start of winding of the third wire wound body is continuous.

  The support part 30 may be omitted. In other words, the wire wound body 20 may be disposed around the base shaft 15 with a posture in which the central axis is parallel, and is not limited to the disposition mode supported by the support portion 30.

  The drawing guide part 40 is supported so as to be rotatable around a rotation axis that is parallel to the central axis of the wire wound body 20 and passes through the base shaft 15, and the guide part 42 is located above each of the first and second wire wound bodies 20. As long as it is configured to be movable to this position, it is not limited to the above configuration. For example, the drawer guiding portion 40 may have a groove-shaped or insertion hole-shaped guiding portion and a leading portion.

  Further, the moving path of the guiding part 42 of the drawer guiding part 40 may be the inner peripheral side or the outer peripheral side from the above-described path. However, from the viewpoint of smoothly pulling out the wire 12 from each wire wound body 20, the draw-out guiding portion 40 is configured to be movable along a path through which the guide portion 42 passes directly above the central axis of the wire wound body 20. Preferably it is.

  Moreover, although the guide part 42 and the drawer | drawing-out part 46 were demonstrated in the example arrange | positioned by the positional relationship which can guide the wire 12 passed toward the drawer | drawing-out part 46 from the guidance part 42 to a horizontal path | route, this has been demonstrated. It is not limited to. The guide part 42 is a part that supports the wire 12 drawn from the wire wound body 20 so as to be drawable, and the lead part 46 is drawn by the guide part 42 to a position immediately above the central axis of the wire wound body 20. 12 is a portion that supports the lead 12 for pulling it out from a position close to the rotation center of the pull-out guiding portion 40. For this reason, the positions of the guide part 42 and the lead-out part 46 are particularly important in the inner and outer directions with respect to the rotation center of the lead-out guide part 40, and are arbitrarily determined within a range that does not hinder the drawing of the wire 12 in the height direction. It is good to be done. However, since the overall height of the wire rod supply device 10 is determined by the position of the drawing portion 46 when the drawing portion 46 is at a position higher than the height of the guiding portion 42, the size of the device should be made compact. In consideration, it is preferable that the position of the lead-out portion 46 is set as low as possible with respect to the guide portion 42. For example, the lead-out portion 46 is provided at a position lower than the guide portion 42 in the height direction, and the wire 12 hung on the lead-out portion 46 extends from the guide portion 42 downward toward the lead-out portion 46 side. Good.
