Description

The present invention relates to winding supports and wire drawing devices.

Reels are known that are used to support wound wires and unwind the wires. For example, in the electric wire reel manufactured by Marvel (model number: E-9101) shown in FIG. 13, the wound electric wire is supported by a plurality of rubber bands spanned by the left and right ring-shaped members. Then, when the tip of the electric wire is pulled, the left and right rings rotate and the electric wire is unwound.

The winding support 1 includes an inner edge support member 20 that can abut on the inner edge a2 of the winding A, a first side support member 30 that can abut on the first side a4 of the winding A, and an operation unit. 40 and. In the example shown in FIG. 2, the winding support 1 includes four inner edge support members 20, but the number of inner edge support members 20 included in the winding support 1 may be two or more. The winding support 1 may include, for example, two, three, five, or six inner edge support members 20. When the winding support 1 includes K inner edge support members 20, the inner edge support member 20 is placed around the rotation axis AX of the winding support 1 every (360 / K) degrees. It is preferable that they are arranged at equal intervals. For example, when K = 3, the inner edge support member 20 is preferably arranged every 120 degrees, and when K = 4, the inner edge support member 20 is preferably arranged every 90 degrees.

The first inner edge support member 20-1 is arranged in the hollow portion a1 of the winding A and can come into contact with the inner edge portion a2 of the winding A. The first inner edge support member 20-1 is movable relative to the first side support member 30 in the out-of-diameter direction, that is, in the direction away from the rotation axis AX (the direction indicated by the arrow AR1 in FIG. 3). .. Further, the first inner edge support member 20-1 can move relative to the first side support member 30 in the inner diameter direction, that is, in the direction toward the rotation axis AX (the direction indicated by the arrow AR2 in FIG. 3). Is.

The second inner edge support member 20-2 is arranged in the hollow portion a1 of the winding A and can come into contact with the inner edge portion a2 of the winding A. The second inner edge support member 20-2 is movable relative to the first side support member 30 in the out-of-diameter direction, that is, in the direction away from the rotation axis AX (the direction indicated by the arrow AR3 in FIG. 3). .. Further, the second inner edge support member 20-2 can move relative to the first side support member 30 in the inner diameter direction, that is, in the direction toward the rotation axis AX (the direction indicated by the arrow AR4 in FIG. 3). Is.

When the number of inner edge support members 20 is 3 or more, if K is defined as an arbitrary natural number of 3 or more, the K inner edge support member 20-K is arranged in the hollow portion a1 of the winding A and wound. It can come into contact with the inner edge portion a2 of the line A. The K inner edge support member 20-K is movable relative to the first side support member 30 in the outer diameter direction and the inner diameter direction.

In the example shown in FIG. 3, the first side support member 30 is in contact with the first side a4 of the winding A. When mounting the winding A on the winding support 1, first, the first side support member 30 has a mounting surface (for example, the ground, a floor surface, etc.) so that the inner edge support member 20 faces upward. ), And secondly, the winding A is placed on the inner side surface 30b of the first side support member 30.

In the example shown in FIG. 2, the first side support member 30 includes a ring frame 31 and a support plate 33 that can come into contact with the first side a4 of the winding A.

The operation unit 40 is an operation unit that changes the position of the first inner edge support member 20-1, the position of the second inner edge support member 20-2, ..., The position of the K inner edge support member 20-K. By operating the operation unit 40, the relative position of the first inner edge support member 20-1 with respect to the first side support member 30, the relative position of the second inner edge support member 20-2 with respect to the first side support member 30, ... ..., The relative position of the K inner edge support member 20-K with respect to the first side support member 30 changes. As will be described later, the operation unit 40 may be an operation unit that changes the position of each inner edge support member 20 by rotating a gear. Alternatively or additionally, the operation unit 40 may be an operation unit that changes the position of each inner edge support member 20 by operating a link mechanism, a cam mechanism, or the like.

In the embodiment, when the operation unit 40 is first operated, the first inner edge support member 20-1 and the second inner edge support member 20-2 are simultaneously arranged in the out-diameter direction (direction indicated by AR1 and AR3, that is, the first first. It moves in the direction away from the central portion 30a of the side support member 30). When the number of inner edge support members 20 is K, when the operation unit 40 is first operated, the K inner edge support members 20 move in the out-of-diameter direction at the same time.

Further, when the operation unit 40 is secondly operated, the first inner edge support member 20-1 and the second inner edge support member 20-2 are simultaneously placed in the inward diameter direction (the direction indicated by AR2 and AR4, that is, the first side portion). It moves toward the central portion 30a of the support member 30). When the number of inner edge support members 20 is K, when the operation unit 40 is secondly operated, the K inner edge support members 20 move in the inner diameter direction at the same time.

In the embodiment, the winding support 1 has an operation unit 40 that simultaneously moves the first inner edge support member 20-1 and the second inner edge support member 20-2 in the out-of-diameter direction. Therefore, by operating the operation unit 40, the inner edge portion a2 of the winding A is suitably supported by the first inner edge support member 20-1 and the second inner edge support member 20-2.

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

Further, as the wire rod B is unwound from the winding support 1, the wire rod B may loosen and the diameter of the inner edge portion a2 of the winding A may increase. In this case, in the embodiment, the first inner edge support member 20-1 and the second inner edge support member 20-2 may be moved in the out-of-diameter direction again at the same time by operating the operation unit 40. That is, in the embodiment, even if the diameter of the inner edge portion a2 changes, by operating the operation portion 40 again, the inner edge portion a2 can be changed to the first inner edge support member 20-1 and the second inner edge support member 20-2. Can be suitably supported by.

Further, in the embodiment, even when the diameter of the inner edge portion a2 of the winding wire A procured by purchase or the like is large, or even when the diameter of the inner edge portion a2 of the winding wire A procured by purchase or the like is small. The inner edge portion a2 of the winding A can be suitably supported by the first inner edge support member 20-1 and the second inner edge support member 20-2 simply by operating the operation portion 40.

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

Therefore, in the embodiment, after winding the wire rod B, the operation unit 40 is operated to move the first inner edge support member 20-1 and the second inner edge support member 20-2 at the same time in the inward direction. By this operation, the close contact between each inner edge 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 electric wire reel shown in FIG. 13 is used for winding the wire rod B, the rubber band and the inner edge portion of the winding A are firmly adhered to each other, and the rubber band is greatly elastically deformed. Therefore, it is difficult to remove the winding A from the rubber band.

The attachment / detachment mechanism may be an attachment / detachment mechanism using a fastener such as a bolt.

When the winding support 1 includes the first side support member 30 and the second side support member 50, the winding A is placed between the first side support member 30 and the second side support member 50. Positioned. In this case, the winding A (or a part of the winding A) does not unintentionally fall off from the winding support 1. Further, in the configuration example 1, the posture of the winding support 1 may be any posture when the wire rod B is unwound by using the winding support 1. For example, the posture of the winding support 1 may be such that the rotation axis AX of the winding support 1 is perpendicular to the ground, or the rotation axis AX of the winding support 1 is parallel to the ground. It may be in such a posture. 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 set so that the rotation axis AX of the winding support 1 is parallel to the ground. In this posture, the winding A may fall off from the winding support 1.

Further, the outer diameter of the first side support member 30 is equal to the outer diameter of the second side support member 50. In this case, with the winding A arranged 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 placed on the ground. By rolling the winding A, the winding A can be easily carried. In the embodiment, the center of gravity of the winding A substantially coincides with the center of the first side support member 30, and the center of gravity of the winding A substantially coincides with the center of the second side support member 50. Therefore, when the first side support member 30 and the second side support member 50 are rolled with respect to the ground, the center of gravity of the winding A hardly moves up and down. Therefore, the winding A can be smoothly transported.

More specifically, the Nth telescopic rod member 70-N includes a base portion 71-N connected to the Nth gear 76-N and a moving portion 72-N screwed to the base portion 71-N. The base portion 71-N is, for example, a screw rod having a male screw 71c-N, and the moving portion 72-N is, for example, a cylindrical member having a female screw. The Nth inner edge support member 20-N is connected to the tip of the moving portion 72-N.

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

(Frame member 80)
In the example shown in FIG. 6, the moving mechanism G of the inner edge support member 20 includes the frame member 80. The frame member 80 is, for example, an annular member. In the example shown in FIG. 6, gears 76 such as a main gear 75, a first gear 76-1, and a second gear 76-2 are arranged inside the frame member 80 (inside the ring), and outside the frame member 80. A moving portion 72 and an inner edge support member 20 are arranged (outside the ring).

In the example shown in FIG. 6, the frame member 80 includes a through hole 81 through which the telescopic rod member 70 is inserted. More specifically, the first telescopic rod member 70-1 is inserted through the first through hole 81-1 and the second telescopic rod member 70-2 is inserted through the second through hole 81-2. The third telescopic rod member 70-3 is inserted through the through hole 81-3, and the fourth telescopic rod member 70-4 is inserted through the fourth through hole 81-4.

When the winding support 1 in the embodiment is used for winding the wire B, a large compressive load acts on the first telescopic rod member 70-1. When the base portion 71-1 of the first telescopic rod member 70-1 moves inward in the radial direction due to the compression load, the meshing state between the first gear 76-1 and the main gear 75 deteriorates, and the first gear 76 -1 and the main gear 75 may not be able to rotate. Therefore, it is preferable that the frame member 80 restricts or prohibits the movement of the base portion 71-1 of the first telescopic rod member 70-1 in the inward direction. Similarly, when N is a natural number of 2 or more, it is preferable that the frame member 80 restricts or prohibits the base portion 71-N of the Nth telescopic rod member 70-N from moving in the inward direction.

(Mechanism that restricts the movement of the base of the telescopic rod member in the inward direction)
With reference to FIGS. 6 to 8, an example of a mechanism in which the frame member 80 restricts the movement of the base of the telescopic rod member in the in-diameter direction will be described. FIG. 7 is a schematic perspective view showing a first gear 76-1, a first telescopic rod member 70-1, a first inner edge support member 20-1, and a first telescopic rod member support portion 73-1. FIG. 8 is a schematic plan view showing a first gear 76-1, a first telescopic rod member 70-1, a first inner edge support member 20-1, and a first telescopic rod member support portion 73-1.

The mechanism that restricts the movement of the base 71-1 of the first telescopic rod member 70-1 in the radial direction (axial movement) is that the base of the other telescopic rod member moves in the radial direction (axial movement). Similar to the mechanism that limits what you do. Therefore, here, a mechanism for restricting the movement of the base portion 71-1 of the first telescopic rod member 70-1 in the inward direction will be described, and the base portion of the other telescopic rod member will move in the inward diameter direction. The description of the limiting mechanism is omitted.

In the example shown in FIG. 8, the first telescopic rod member support portion 73-1 includes a bracket 730-1, a guide cylinder 732-1, a movement restriction member 733-1, and a movement restriction member support portion 734-1. To prepare for.

The bracket 730-1 is fixed to the frame member 80. In the example shown in FIG. 7, a hole 730c-1 is provided in the plate portion of the bracket 730-1, and a fastening member such as a screw or a bolt is inserted into the hole 730c-1 and the hole of the frame member 80, and 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 shown in FIG. 8, the cylinder portion of the bracket 730-1). The fixing is performed by a fastening member such as a screw or a bolt. 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 portion 72-1 of the first telescopic rod member 70-1. In the example shown in FIG. 8, the outer surface 72a-1 of the moving portion 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 portion 71-1 of the first telescopic rod member 70-1 and restricts the movement of the base portion 71-1 in the in-diameter direction. In other words, the frame member 80 supports an in-diameter load acting on the base portion 71-1 of the first telescopic rod member 70-1 via the movement limiting member 733-1. In the example shown in FIG. 8, the stepped portion 71a-1 (shoulder portion) of the base portion 71-1 comes into contact with the movement limiting member 733-1. Therefore, the base portion 71-1 of the first telescopic rod member 70-1 cannot move in the inward direction. As a result, the meshing state between the first gear 76-1 arranged at the base end portion of the base portion 71-1 and the main gear 75 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 inward movement of the base 71-1 while allowing the base 71-1 to rotate about the longitudinal axis AX2.

The movement limiting member support portion 734-1 supports the movement limiting member 733-1. In the example shown in FIG. 8, the movement limiting member 733-1 is arranged between the movement limiting member support portion 734-1 and the step portion 71a-1 of the first telescopic rod member 70-1. Further, the movement limiting member support portion 734-1 is arranged between the first gear 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 arranged 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 portion 734-1.

The moving portion 72-1 of the first telescopic rod member 70-1 and the base portion 71-1 of the first telescopic rod member 70-1 are screwed together (see the portion indicated by the arrow E in FIG. 8). ). Therefore, when the base portion 71-1 rotates around the longitudinal axis AX2, the moving portion 72-1 moves in the out-of-diameter direction (the direction indicated by the arrow AR1) or the in-diameter direction (the direction indicated by the arrow AR2). The first inner edge support member 20-1 is connected to the tip end portion of the moving portion 72-1, and the first gear 76-1 is connected to the base end portion of the base portion 71-1.
