  However, such a winding device rotates the attachment shaft 104 in the circumferential direction of the shaft member 100 to extract the object wound around the winding portion 101, so that the male screw portion 102 and the attachment shaft 104 of the shaft member 100 are rotated. It is necessary to release the threaded engagement with the female thread portion 103, remove the mounting shaft 104 from the shaft member 100, and move the winding portions 101,... In the axial direction of the shaft member 100. Therefore, in order to extract the wound object, such a winding device needs to join (recover) the separated part to separate one part of the apparatus and wind the object again. The work required to extract things is complicated and takes a long time.

  Therefore, in view of such circumstances, an object of the present invention is to provide a winding device that can simplify the work necessary for extracting a wound object.

The at least one winding portion is provided with a displaceable support portion at a position where it can be displaced inward.

  According to the present invention, the support portion supports the winding portion and restricts the winding portion from being displaced inward, and the position where the restriction is released and the winding portion can be displaced inward. And can be displaced. Thereby, after winding a long object around a plurality of winding parts that are restricted from being displaced inwardly by at least one winding part, at least one winding part is released from the restriction. By displacing inward so as to be separated from the object, the wound object can be extracted from the winding unit. Therefore, it is not necessary to separate one part of the apparatus or join the separated parts to wind and extract a long object around the plurality of winding parts.

  Further, in the winding device according to the present invention, a shaft member in which the winding portion is disposed around the axis line so that the axial direction is along the longitudinal direction of the winding portion, and the shaft member is inserted into the shaft member.

  Further, the moving part 3 is provided with a spherical gripping part 13 that can be gripped by the operator at one end in the axial direction, and through a fixing means (not numbered) to protect the operator's hand. Thus, a plate-shaped safety rod 14 fixed to the moving unit main body 9 is disposed so as to be orthogonal to the axial direction. The safety rod 14 is configured to come into contact with the end of the winding unit 1 (plate member 7) when the moving unit 3 moves a predetermined distance in the axial direction of the shaft member 2, and the moving unit 3 is connected to the shaft member 2. It is configured to be able to regulate movement of a predetermined distance or more in the axial direction.

  The moving unit 3 is also referred to as a position for winding the object X around the winding unit 1 (hereinafter also referred to as “winding position”) and a position for extracting the object X from the winding unit 1 (hereinafter also referred to as “extraction position”). ) And can be held.

Specifically, when the safety rod 14 comes into contact with the end of the winding unit 1 (plate member 7) and is rotated in the circumferential direction so as to be in sliding contact with the second hole 16 along the circumferential direction. The protrusion 17 is configured to be guided.

  Further, the moving part 3 has an outer periphery of the restricting parts 19, ... that can lock the take-up parts 1, ... at a position where the support part 4 restricts the winding part 1 from being displaced inwardly (in the width direction). The winding part 1,... Is configured to be capable of restricting relative displacement of the winding part 1,. Specifically, the restricting portion 19 is formed in a groove shape along the axial direction on the outer peripheral portion of the large diameter portion 11 (moving portion 3), and the winding portions 1,... Are relatively displaced in the circumferential direction of the shaft member 2. To regulate.

  The description of the configuration of the winding device according to the present embodiment is as described above. Next, the operation of the winding device according to the present embodiment will be described.

  First, in the winding device, the shaft member 2 is driven in a state where the supporting portion 4 supports the winding portions 1,... And is prevented from being displaced in the width direction, that is, held in the winding position. When rotating in the circumferential direction, the winding portions 1,... Pivoted to the base portion 5 are integrally rotated via the base portion 5 fixed to the shaft member 2. Then, the long object X is wound around the winding portions 1,..., Which are rotated in the circumferential direction of the shaft member 2 and restricted in the width direction, while reciprocating in the axial direction. At this time, a force directed toward the shaft member 2 from the object X around which the winding unit 1 is wound acts, but the support unit 4 supports the winding units 1,. it can.

  Further, the moving portion 3 (supporting portion 4) also has a shaft formed by locking (contacting) the first hole portion 15 provided in the moving portion main body 9 along the axial direction with the protruding portion 17 of the shaft member 2. The member 2 rotates integrally with the winding unit 1. Thereby, when the winding part 1 is restricted from being displaced in the width direction by the support part 4, the groove-shaped regulation part 19 provided on the outer peripheral part of the moving part 3 (large diameter part 11) is the winding part. In order to lock 1 (rotating member 8), the winding portions 1, ... are restricted from being displaced relative to the moving portion 3 (supporting portion 4) in the circumferential direction of the shaft member 2. Therefore, as the object X is wound, the circumferential force of the shaft member 2 acts on the winding unit 1, but the winding unit 1 is a shaft member against the moving unit 3 (support unit 4). Since relative displacement in the circumferential direction over the axial direction of 2 is restricted, the object X can be stably wound around the winding portions 1.

  Then, in order to extract the wound object X from the winding units 1,..., First, the rotation of the shaft member 2 is stopped, and the rotation of the winding unit 1 and the moving unit 3 (support unit 4) is stopped. . When the operator grips the grip portion 13 and is biased toward the other side (base portion 5 side) of the shaft member 2 in the axial direction, the moving portion 3 inserted into the shaft member 2 is moved to the axis of the shaft member 2. The support part 4 provided in the outer peripheral part of the moving part 3 is displaced toward the axial direction of the shaft member 2 along with the displacement along the direction.

  Then, when the winding part 1 receives the force on the shaft member 2 side (width direction) due to the force received from the object X or the weight of the winding part 1, the winding part 1, that is, one side in the longitudinal direction. The rotating member 8 provided in the is guided along the reduced diameter portion 12. Therefore, since the winding part 1 rotates around the fulcrum part 6 provided on the other side in the longitudinal direction, the shaft member 2 side (width) is set so that the winding part 1 is released from the restriction and separated from the object X. Direction).

  And if the moving part 3 moves to the axial direction of the shaft member 2 until the safety rod 14 contacts the winding parts 1,..., The winding part 1 is removed from the object X to the extent that the object X can be extracted. Displace to move away. Therefore, when the moving portion 3 is rotated in the circumferential direction of the shaft member 2 so that the safety rod 14 is in sliding contact with the winding portions 1,..., The protruding portion of the shaft member 2 is inserted into the second hole portion 16 along the circumferential direction. 17 is guided. At this time, since the moving part 3 moves in the axial direction of the shaft member 2, the rotating member 8 is located on one side in the axial direction of the shaft member 2 rather than the large diameter part 11 or the reduced diameter part 12. That is, since the support portion 4 is located at the extraction position, the locking by the restriction portion 19 is also released, and the rotating member 8 can be relatively displaced with respect to the moving portion 3 in the circumferential direction of the shaft member 2.

  Since the elastic body 18 biases the moving part 3, the inner edge of the second hole 16 of the moving part 3 is locked (contacted) with the protrusion 17 of the shaft member 2, and the moving part 3 (supporting part) 4) is held. Thereby, in order to extract the target object X from the winding parts 1,..., The winding parts 1,. Therefore, as shown in FIG. 6, after winding the long object X around the plurality of winding parts 1,... Restricted to be displaced, the winding parts 1,. By displacing in the width direction so as to be separated from the object X, the object X wound from the winding portions 1,... Can be extracted.

  Then, to wind the object X around the winding portions 1,... Again, the operator guides the protrusion 17 of the shaft member 2 to the second hole portion 16 along the circumferential direction, and the moving portion 3 moves in the circumferential direction. To be rotated. Then, since the elastic body 18 urges the moving portion 3, the projection 17 is guided to the first hole portion 15 along the axial direction, and the moving portion 3 is displaced along the axial direction of the shaft member 2. Therefore, the support part 4 supports the winding parts 1... And is displaced to a position that restricts displacement in the width direction, that is, a winding position.

  And since the moving part 3 continues to be urged | biased by the elastic body 18, the inner edge of the 1st hole 15 along an axial direction is latched (contact | abutted) to the projection part 17, and the moving part 3 (support part 4). Is retained. Therefore, in a state where the support portion 4 is held at the winding position, the object X can be wound around the plurality of winding portions 1,.

  From the above, in the winding device according to the present embodiment, the support unit 4 supports the winding units 1,..., And can restrict the winding unit 1 from being displaced in the width direction. ,... Can be displaced to a position displaceable in the width direction, so that a long object X is wound around the plurality of winding parts 1, and the object X is extracted from the winding parts 1. However, it is not necessary to separate one part of the apparatus or to join the separated parts. Therefore, since the operation | work which extracts the target object X can be simplified, the time required for the operation | work which extracts the wound target object X can also be shortened, for example.

  Further, in the winding device according to the present embodiment, when the moving unit 3 is displaced along the axial direction of the shaft member 2, the support unit 4 supports the winding units 1,. Can be displaced to a position where the restriction is restricted and a position where the restriction is released. Therefore, for example, since the support part 4 can be displaced only by urging the moving part 3 in the axial direction of the shaft member 2, the work of extracting the object X can be further simplified.

  In the winding device according to the present embodiment, the winding unit 1 winds the object X, but the regulating unit 19 locks the winding units 1,. On the other hand, relative displacement in the circumferential direction of the shaft member 2 is restricted. Therefore, for example, since the winding unit 1 can be prevented from being bent (deformed) even when it receives a circumferential force from the object X, the design strength of the winding unit 1 in the circumferential direction can be reduced.

  The winding device according to the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.

  Moreover, although the winding apparatus concerning the said embodiment demonstrated the case where winding part 1, ... rotated in the circumferential direction of the shaft member 2, it is not restricted to such a case, winding part 1, ... rotates. Alternatively, the object X may be wound around the winding portions 1.

  In the winding device according to the above-described embodiment, when the shaft member 2 is driven and rotated in the circumferential direction, the winding unit 1 rotates in the circumferential direction, and the moving unit 3 (supporting unit 4) also rotates. Although the case where it rotates to a direction was demonstrated, it is not restricted to such a case, The case where at least any one of the shaft member 2 and the moving part 3 (support part 4) does not rotate may be sufficient.

  Moreover, although the winding apparatus concerning the said embodiment demonstrated the case where the winding part 1 was pivotally attached to the base 5, and the one side of a longitudinal direction displaced in the width direction, it is not restricted to such a case, For example, FIG. As shown in FIG. 4, the winding unit 20 may be displaced in the width direction over the longitudinal direction. Specifically, the winding unit 20 is supported by a first rotating member 23 supported by a first support unit 22 provided on the moving unit 21 and a second support unit 24 provided on the moving unit 21. 2 is provided, and is configured to be capable of restricting displacement inward (in the width direction), and is provided with an engaging portion 27 that engages with the base portion 26, and is displaced in the axial direction of the shaft member 28. It may be configured such that it can be regulated.

  Moreover, although the winding apparatus concerning the said embodiment demonstrated the case where all the some winding parts 1, ... were displaceable inward (width direction), it is not restricted to such a case, At least 1 winding part 1 may be displaceable in the width direction. In short, it is sufficient that at least one of the winding units 1,... Moves in the width direction and the wound object X is separated from the object X so that it can be extracted.

  Moreover, although the winding device concerning the said embodiment demonstrated the case where the rotating member 8 of the winding part 1 was guided to the diameter reduction part 12 in the moving part 3, and the winding part 1 was cancelled | regulated, For example, the winding unit and the moving unit (reduced diameter portion) may be in sliding contact with each other, and a rotating member provided on the support unit is provided on the outer edge of the winding unit or the winding unit. It may be guided by a cam (plate cam, groove cam).

  Moreover, although the winding apparatus concerning the said embodiment demonstrated the case where the four winding parts 1 were provided, it is not restricted to this case, The winding part 1 should just be provided two or more.

  Further, the winding device according to the embodiment includes the reduced diameter portion 12 that decreases in diameter from the large diameter portion 11 toward one side in the axial direction of the shaft member 2, and the moving portion 3 extends in the axial direction of the shaft member 2. Although the case where the support part 4 is displaced to the position that restricts the displacement of the winding part 1 in the width direction by moving to one side has been described, the present invention is not limited to this case. A diameter-reducing portion that is reduced in diameter toward the other side in the axial direction of the member 2 is provided, and the winding portion 1 is displaced in the width direction by moving the moving portion to the other side in the axial direction of the shaft member 2. The case where the support part 4 is displaced to the position to restrict | limit may be sufficient.
