Fig. 3 is a cross-sectional view taken in the direction of the arrow J-J in Fig. 2 .

Referring to Fig. 1, the winding A is formed by winding a wire B such as an electric wire. The winding A has a hollow part a1, an inner edge part a2 contacting the hollow part a1, an outer edge part a3, a first side part a4, and a second side part a5 . When sending out the wire B, the first end b1 of the wire B is pulled.

As shown in FIG. 2, the winding support tool 1 in embodiment is a mechanism which supports the winding A. The winding support 1 comprises an internal combustion support member 20 abutable against the inner edge a2 of the winding A, and a first side support member capable of abutting on the first side a4 of the winding A. (30) and an operation unit (40). In the example shown in FIG. 2, although the winding support tool 1 is provided with the four internal combustion support members 20, if the number of the internal combustion support members 20 with which the winding support tool 1 is equipped is two or more, do. The winding support tool 1 may be equipped with the internal combustion support member 20 of 2, 3, 5, or 6 pieces, for example. Moreover, when the winding support tool 1 is provided with the K number of internal combustion support members 20, the internal combustion support member 20 is the circumference|surroundings of the rotation axis AX of the winding support tool 1, (360/) K) It is preferable to arrange at equal intervals for every degree. For example, when K=3, the internal combustion support member 20 is arrange|positioned every 120 degrees, and when K=4, it is preferable that the internal combustion support member 20 is arrange|positioned every 90 degrees.

The first internal combustion support member 20 - 1 is disposed in the hollow part a1 of the winding A, and can abut against the internal edge part a2 of the winding A. The first internal combustion support member 20 - 1 is relative to the first side support member 30 in the outward direction, that is, in a direction away from the rotation axis AX (a direction indicated by arrow AR1 in FIG. 3 ). can be moved In addition, the first internal combustion support member 20-1 is attached to the first side support member 30 in the inner direction, that is, in the direction toward the rotation axis AX (the direction indicated by the arrow AR2 in FIG. 3 ). can move relative to each other.

The second internal combustion support member 20 - 2 is disposed in the hollow portion a1 of the winding A, and can abut against the inner edge portion a2 of the winding A. The second internal combustion support member 20 - 2 is relative to the first side support member 30 in the outward direction, that is, in a direction away from the rotation axis AX (a direction indicated by arrow AR3 in FIG. 3 ). can be moved In addition, the second internal combustion support member 20 - 2 is attached to the first side support member 30 in a direction within the precincts, that is, in a direction toward the rotation axis AX (a direction indicated by arrow AR4 in FIG. 3 ). can move relative to each other.

When the number of the internal combustion support members 20 is three or more, if K is defined as an arbitrary natural number of three or more, the Kth internal combustion support member 20-K is disposed in the hollow portion a1 of the winding A, , it is possible to abut against the inner edge (a2) of the winding (A). The Kth internal combustion support member 20 -K is movable relative to the first side support member 30 in an outward direction and an inward direction.

In the example described in FIG. 3 , the first side support member 30 abuts against the first side a4 of the winding A. When attaching the winding A to the winding support 1, firstly, so that the internal combustion support member 20 faces upward, the 1st side support member 30 has a mounting surface ( For example, the winding A is mounted on the inner side surface 30b of the first side support member 30 secondly.

In the example shown in FIG. 2, the 1st side support member 30 is provided with the ring frame 31 and the support plate 33 which can abut against the 1st side part a4 of the winding A.

The operation unit 40 includes a position of the first internal combustion support member 20-1, a position of the second internal combustion support member 20-2, ... , an operation unit for changing the position of the K-th internal combustion support member 20 -K. By operating the operation portion 40, the relative position of the first internal combustion support member 20-1 with respect to the first side support member 30, the first side support member 30 of the second internal combustion support member 20-2 ) relative to , … , the relative position of the K-th internal combustion support member 20 -K with respect to the first side support member 30 changes. As mentioned later, the operation part 40 may be an operation part which changes the position of each internal combustion support member 20 by rotating a gearwheel. Alternatively or additionally, the operation unit 40 may be an operation unit for changing the position of each internal combustion support member 20 by operating a link mechanism, a cam mechanism, or the like.

In the embodiment, when the operation unit 40 is operated for the first time, the first internal combustion support member 20-1 and the second internal combustion support member 20-2 simultaneously move in directions indicated by the outward directions AR1 and AR3, that is, , in a direction away from the central portion 30a of the first side support member 30 ). In addition, when the number of the internal combustion support members 20 is K, when the operation part 40 is operated first, the K number of internal combustion support members 20 simultaneously move in the outward direction.

Further, when the operation unit 40 is operated a second time, the first internal combustion support member 20-1 and the second internal combustion support member 20-2 simultaneously move in the directions indicated by the inner-prear directions AR2 and AR4, that is, the second internal combustion support member 20-1. 1 moves toward the central portion 30a of the side support member 30). In addition, when the number of the internal combustion support members 20 is K, when the operation part 40 is operated a second time, the K number of internal combustion support members 20 simultaneously move in the inner-prear direction.

In embodiment, the winding support tool 1 has the operation part 40 which moves the 1st internal combustion support member 20-1 and the 2nd internal combustion support member 20-2 simultaneously in an outward direction. For this reason, by operating the operation part 40, the internal edge part a2 of the winding A is suitably supported by the 1st internal combustion support member 20-1 and the 2nd internal combustion support member 20-2. do.

In particular, the first internal combustion support member so that the distance between the first internal combustion support member 20-1 and the rotation shaft AX and the distance between the second internal combustion support member 20-2 and the rotation shaft AX are equal to each other When the (20-1) and the second internal combustion support member 20-2 are simultaneously moved in the outward direction, the center of gravity of the winding A and the rotational axis AX of the winding support 1 generally coincide with each other. do. In this case, the winding support 1 is rotatably supported by an arbitrary winding support frame (for example, the winding support frame 99 shown in FIG. 4), and the wound wire B ) from the winding support 1, the vibration of the winding A is suppressed.

Moreover, as the wire B is sent out from the winding support tool 1, the wire B becomes loose, and the diameter of the inner edge part a2 of the winding A may expand. In this case, in the embodiment, by operating the operation unit 40 , the first internal combustion support member 20-1 and the second internal combustion support member 20-2 may be moved again in the outward direction at the same time. That is, in the embodiment, even if the diameter of the internal edge part a2 changes, by operating the operation part 40 again, the said internal edge part a2 is adjusted to the 1st internal combustion support member 20-1 and the 2nd internal combustion support member. It is possible to properly support by (20-2).

In addition, in the embodiment, even when the diameter of the inner edge portion a2 of the winding A procured by purchase or the like is large, even when the diameter of the inner edge portion a2 of the winding A procured by purchase or the like is small, Only by operating the operation part 40, the internal edge part a2 of the winding A is suitably supported by the 1st internal combustion support member 20-1 and the 2nd internal combustion support member 20-2. it is possible

In addition, the winding support tool 1 in embodiment can be used also when winding up the wire B. When the wire rod B is wound around the winding support 1 , a force acts on each internal combustion support member 20 in the inner direction (directions indicated by arrows AR2 and AR4 in FIG. 3 ). As a result, each of the internal combustion support members 20 and the inner edge portion a2 of the winding A are firmly in close contact with each other. In this state (the state in which each internal combustion supporting member 20 and the inner edge portion a2 of the winding A are firmly in close contact), the wound winding A, that is, the recovered winding A, is It is difficult to remove from the earth 1 .

Then, in the embodiment, after the wire rod B is wound, the operation unit 40 is operated to move the first internal combustion support member 20-1 and the second internal combustion support member 20-2 simultaneously in the inner direction. make it By this operation, the close contact between each internal combustion support member 20 and the inner edge portion a2 of the winding A is released, and the winding A can be easily removed from the winding support 1 . On the other hand, when the conventional wire reel shown in Fig. 13 is used for winding the wire B, the rubber band and the inner edge of the winding A are strongly adhered to each other, and large elastic deformation occurs in the rubber band. For this reason, it is difficult to remove the winding A from the rubber band.

(optional additional configuration example)

With reference to FIG. 2 and FIG. 3, arbitrary additional structural examples employable in the embodiment will be described.

(Configuration Example 1)

In the example (configuration example 1) described in FIG. 3, the winding support tool 1 is equipped with the 2nd side support member 50 which can abut against the 2nd side part a5 of the winding A. The second side support member 50 is detachable with respect to the body portion 3 of the winding support device 1 . Further, the main body portion 3 includes an internal combustion support member 20 such as a first internal combustion support member 20-1 and a second internal combustion support member 20-2, and a first side support member 30 . do. In addition, any attachment/detachment mechanism is employable as an attachment/detachment mechanism for attaching and detaching the 2nd side support member 50 to the main-body part 3 . The attachment/detachment mechanism may be a attachment/detachment mechanism using fasteners, such as a bolt.

When the winding support 1 has a first side support member 30 and a second side support member 50 , the winding A has a first side support member 30 and a second side support member 50 . It is positioned between 50. In this case, the winding A (or a part of the winding A) does not fall off from the winding support tool 1 unintentionally. Moreover, in the structural example 1, when sending out the wire B using the winding support tool 1, the attitude|position of the winding support tool 1 may be any attitude|position. For example, the attitude|position of the winding support tool 1 may be the attitude|position in which the rotational axis AX of the winding support tool 1 becomes perpendicular to the ground, and the rotational axis AX of the winding support 1 is parallel to the ground. This may be the attitude. On the other hand, when the winding support 1 does not include the second side support member 50 , the posture of the winding support 1 is determined so that the rotational axis AX of the winding support 1 is in contact with the ground. When it is set as the attitude|position used as parallel, there exists a possibility that the winding A may fall off from the winding support tool 1 .

When attaching the winding A to the winding support 1, firstly, the 1st side support member 30 is a mounting surface (for example, so that the internal combustion support member 20 may face up) The winding A is placed on the inner surface 30b of the first side support member 30 secondly, and thirdly, the second side support member 50 ) is attached to the body portion 3 , and fourthly, a plurality of internal combustion support members 20 including the first internal combustion support member 20 - 1 and the second internal combustion support member 20 - 2 are simultaneously moved in the awe-inspiring direction.

In Structural Example 2, the outer shape of the first side support member 30 is a circular shape, and the outer shape of the second side support member 50 is a circular shape. In addition, the outer diameter of the first side support member 30 is the same as the outer diameter of the second side support member 50 . In this case, with the winding A disposed between the first side support member 30 and the second side support member 50 , the first side support member 30 and the second side support member 50 are By rolling against the ground, the winding A can be easily transported. Further, in the embodiment, the center of gravity of the winding A generally coincides with the center of the first side support member 30 , and the center of gravity of the winding A generally coincides with the center of the second side support member 50 . do. For this reason, when the 1st side support member 30 and the 2nd side support member 50 are rolled with respect to the ground, the center of gravity of the winding A hardly moves up and down. For this reason, it is possible to convey the winding A smoothly.

More specifically, the first telescopic rod member 70-1 includes a base 71-1 connected to the first cog wheel 76-1, and a moving part 72 screwed to the base 71-1. -1) is provided. The base 71-1 is, for example, a screw rod having an external screw 71c-1, and the moving part 72-1 is, for example, a cylindrical member having a female screw. A first internal combustion support member 20-1 is connected to the distal end of the moving part 72-1.

When the operation unit 40 is operated first, the main gear 75 rotates, and the first gear 76-1 meshing with the main gear 75 rotates together with the base 71-1. When the base 71-1 rotates, the moving part 72-1 moves in a direction closer to the inner edge a2 of the winding A together with the first internal edge support member 20-1.

Similarly, when N is a natural number of 2 or more, the N-th gear 76-N (for example, a bevel gear) is connected to the N-th telescopic rod member 70-N. When the N-th gear wheel 76-N rotates, the N-th telescopic rod member 70-N expands or contracts. More specifically, the N-th telescoping rod member 70-N includes a base 71-N connected to the N-th cogwheel 76-N, and a moving part 72 screwed to the base 71-N. -N) is provided. The base 71-N is, for example, a screw rod having an external screw 71c-N, and the moving part 72-N is, for example, a cylindrical member having a female screw. An N-th internal combustion support member 20-N is connected to the distal end of the moving part 72-N.

When the base 71-N rotates, the moving part 72-N moves in a direction closer to the inner edge a2 of the winding A together with the N-th internal edge support member 20 -N.

(Frame member 80)

In the example described in FIG. 6 , the moving mechanism G of the internal combustion support member 20 includes the frame member 80 . The frame member 80 is, for example, an annular member. In the example described in FIG. 6, gear wheels, such as the main gear 75, the 1st gear 76-1, and the 2nd gear 76-2, on the inner side (inside of the ring) of the frame member 80. 76 is disposed, and on the outside (outside of the ring) of the frame member 80 , the moving part 72 and the internal combustion support member 20 are disposed.

In the example described in FIG. 6 , the frame member 80 has a through hole 81 through which the telescopic rod member 70 is inserted. More specifically, the first elastic rod member 70-1 is inserted through the first through hole 81-1, and the second elastic rod member 70-2 is inserted into the second through hole 81-2. is inserted through, the third telescoping rod member 70-3 is inserted through the third through hole 81-3, and the fourth telescoping bar member 70-4 is inserted through the fourth through hole 81-4. is inserted through.

When the winding support tool 1 in the embodiment is used for winding the wire rod B, a large compressive load acts on the first elastic rod member 70-1. When the base 71-1 of the first telescopic rod member 70-1 moves toward the inner direction by the compressive load, the first gear 76-1 and the main gear 75 are engaged. is deteriorated, and there is a fear that the first gear 76-1 and the main gear 75 cannot be rotated. For this reason, it is preferable that the frame member 80 restrict|limits or prohibits the base 71-1 of the 1st telescopic-bar member 70-1 from moving in the direction of the inside. Similarly, when N is a natural number equal to or greater than 2, it is preferable that the frame member 80 restricts or prohibits the movement of the base 71-N of the N-th telescopic rod member 70-N in the inner direction. .

(Mechanism for restricting movement of the base of the telescopic bar member in the inner direction)

An example of a mechanism in which the frame member 80 restricts the movement of the base of the telescopic rod member in the inner precinct direction will be described with reference to FIGS. 6 to 8 . 7 shows the first cog wheel 76-1, the first expansion rod member 70-1, the first internal combustion support member 20-1, and the first expansion rod member support part 73-1. It is a schematic perspective view showing. 8 shows the first cog wheel 76-1, the first telescopic rod member 70-1, the first internal combustion support member 20-1, and the first telescopic rod member support part 73-1. It is a schematic plan view showing.

The mechanism for restricting the movement of the base 71-1 of the first telescopic rod member 70-1 in the inner direction (axial movement) is that the base of the other telescopic rod member moves in the inner direction (axial movement). It is the same mechanism that restricts what to do. Therefore, here, a mechanism for restricting the movement of the base 71-1 of the first telescopic rod member 70-1 in the inner direction will be described, and the movement of the base of the other telescopic rod member in the inner direction will be described. A description of the limiting mechanism will be omitted.

In the example shown in FIG. 8, the 1st telescopic-bar member support part 73-1 includes the bracket 730-1, the guide cylinder 732-1, the movement limiting member 733-1, and a movement limiting member. A support part 734-1 is provided.

The bracket 730 - 1 is fixed to the frame member 80 . In the example described in FIG. 7 , a hole 730c-1 is formed in the plate portion of the bracket 730-1, and fastening members such as screws and bolts are provided in the hole 730c-1 and the hole of the frame member 80. is inserted, the bracket 730 - 1 and the frame member 80 are fixed.

The guide cylinder 732-1 is fixed to the bracket 730-1 (in the example described in FIG. 8, the cylinder part of the bracket 730-1). The said fixing is performed by fastening members, such as a screw and a bolt. In addition, the guide cylinder 732-1 and the bracket 730-1 may be integrally molded members.

As described above, since the bracket 730 - 1 and the guide cylinder 732-1 are directly or indirectly fixed to the frame member 80 , they do not move relative to the frame member 80 .

The guide cylinder 732-1 slidably supports the moving part 72-1 of the 1st telescopic rod member 70-1. In the example shown in FIG. 8, the outer surface 72a-1 of the moving part 72-1 slides with respect to the inner surface 732a-1 of the guide cylinder 732-1.

The movement limiting member 733-1 is a member that comes into contact with the base 71-1 of the first telescopic rod member 70-1 and restricts the movement of the base 71-1 in the inner precinct direction. In other words, the frame member 80 supports the inward load acting on the base 71-1 of the first telescopic rod member 70-1 via the movement limiting member 733-1. In the example described in FIG. 8 , the end 71a-1 (shoulder) of the base 71-1 is in contact with the movement limiting member 733-1. For this reason, the base 71-1 of the first telescopic rod member 70-1 cannot move toward the inside of the precinct. As a result, the meshing state between the first gear 76-1 and the main gear 75 disposed at the proximal end of the base 71-1 does not deteriorate.

The movement limiting member 733-1 is, for example, a thrust bearing, a thrust washer, or the like. The movement limiting member 733-1 restricts the movement of the base 71-1 in the inner precinct direction, while allowing the base 71-1 to rotate about the longitudinal axis AX2.

The movement limiting member support part 734 - 1 supports the movement limiting member 733 - 1 . In the example described in FIG. 8 , the movement limiting member 733 - 1 is disposed between the movement limiting member support portion 734 - 1 and the end portion 71a - 1 of the first telescopic rod member 70 - 1 . is placed in Moreover, the movement limiting member support part 734-1 is arrange|positioned between the 1st gear wheel 76-1 and the bracket 730-1.

Alternatively, the movement limiting member 733-1 may be supported by the frame member 80 or the bracket 730-1. For example, the movement limiting member 733 - 1 may be disposed between the frame member 80 and the bracket 730 - 1 . In this case, the frame member 80 or the bracket 730 - 1 functions as the movement limiting member support 734 - 1 .

The moving part 72-1 of the 1st telescoping rod member 70-1 and the base 71-1 of the 1st telescoping rod member 70-1 are mutually screwed together (in FIG. 8). See the section indicated by arrow E). For this reason, when the base 71-1 rotates around the longitudinal axis AX2, the moving part 72-1 moves in an outward direction (direction indicated by arrow AR1) or inward direction (direction indicated by arrow AR2). move to In addition, a first internal combustion support member 20-1 is connected to the distal end of the moving part 72-1, and a first cogwheel 76-1 is connected to the base end of the base 71-1, have.
