DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a pair of flanges opposing each other and a drum sandwiched between the two flanges, and the drum has a flexible shape such as a tape, a wire or a chain. The present invention relates to a distribution reel used for winding and transporting a long object having a property, passing a support shaft through a center hole at a use site, and sequentially feeding and using the wound long object.

[0002]

2. Description of the Related Art Conventionally, a distribution reel of this kind is used for winding a required long object on a reel as described above, and then pulling out the reel while sequentially pulling it out for use. In addition, there is a need for a variety of sizes in which the distance between the flange bodies, the size of the flange bodies, and the size of the drum body serving as the winding shaft are different. Also,
After the transported object is fed out and used, it is collectively forwarded for reuse and provided for reuse.

[0003] Therefore, in this kind of conventional general distribution reel, during transport from a manufacturer to a take-up site (a factory or the like) of a conveyed object, or from a place where a conveyed object is used for use, it is necessary to reuse the reel. During the transfer, the empty reel must be transferred in the same bulk as in the case of transfer in the state where the transported material is wound, so that it can be disassembled and assembled. There has been proposed a distribution reel having a structure capable of transporting a small volume (bulk).

[0004] However, in a commercially available assembling reel which can be disassembled and assembled at present, as shown in FIG. 10, it projects outward from the end face of the drum body 3A and the hook directions are opposite to each other. Pair of projections 8A, 8A
Are projected to form small holes 10A, 1A formed in the flange body 2A.
0A, and swings using the elastic force of the projection itself as shown by a chain line f, thereby forming the small holes 10A, 1A.
OA was engaged. In addition, the relative rotation stopping force between the drum body 3A and the flange body 2A also depends only on the elastic restoring force of the projections 8A, 8A.

[0005]

Therefore, the projection 8A is
The swing at the time of assembling and fitting, the swing at the time of disassembly at the time of disassembly, and especially the blocking force of the relative rotational force between the flange body 2A and the drum body 3A are all controlled by the swing direction of the projection 8A itself. Since the elastic force is borne, the swing restoring force of the projection 8A rapidly decreases, and the stability of the engaging force in the assembled state is suddenly impaired, which is unsuitable for repeated use. there were.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve such problems of the conventional product, and it is possible to easily assemble and disassemble, but also to assemble the flange body and the drum body by repeated assembling and disassembling. It is an object of the present invention to provide a distribution reel capable of performing reliable assembling engagement even after repeated use, with almost no decrease in engagement force.

[0010]

Embodiments of the present invention will be described below with reference to the drawings. First, the distribution reel referred to in the present invention is an expression for distinguishing from a fishing reel, a line reel and other reels, and is an expression for clarifying that it is an industrial use reel. Reel 1 according to the present invention
Is a reel formed by a pair of flange bodies 2 and 2 and a drum body 3 arranged and fixed between the flange bodies and serving as a winding shaft.

FIG. 1 to FIG. 7 show a first embodiment of a distribution reel according to the present invention, in which two disk-shaped flange members 2, 2 each having a flat plate-like circular shape and their flanges are shown. The two flange bodies 2, 2 are arranged between the bodies 2, 2, and the drum body 3 is connected and fixed to each other.

The drum body 3 includes an outer cylinder 4 which is arranged concentrically at an interval and an inner cylinder 5 which forms a shaft hole 7, and the inner cylinder 5 and the outer cylinder 4 are formed at an intermediate portion in the axial direction. The drum body 3 slightly protrudes outward from upper and lower opening surfaces in the figure, and has a length L in a side view.
In this embodiment, a plurality of hooks 8 are formed on the one side, and two elastic lock bodies 9 are formed on one side.

The hooks 8 are opposite to each other such that the upper and lower ends of the plate projecting in the axial direction along the inner surface of the outer cylinder 4 form a Z-shape at the upper and lower ends of the plate. It is formed so as to protrude in the direction, and is bent and formed so as to face the same circumferential direction on each opening surface side. Further, the elastic lock body 9 has a connecting portion 9a protruding from the vicinity of one open end face of the drum body 3 toward the inner surface side.
From the other end to the same plane as the other open end face, and is formed such that the distal end thereof swings in the radial direction with the connecting portion 9a as a swing base point. As shown in FIG. 4, the elastic lock body 9 in this embodiment has two opposing portions on the upper surface opening side of the drum body 3 and the connecting portions 9a, 9a protruding on the upper surface opening side facing the lower surface opening side. It is provided in four places, two places protruding.

The flange body 2 has a shaft hole 13 at the center thereof for fitting with the inner cylinder 5 of the drum body 3, and the outer peripheral portion thereof corresponds to the hook bodies 8 of the drum body 3. Six engagement holes 10 that engage the hook body at the locations.
And two unlocking operation holes 11 at locations corresponding to the elastic lock bodies 9. Furthermore, on the inner surface side of the flange body 2, that is, the surface on the side facing the drum body 3,
As shown in the flange body 2 shown in the lower part of FIG. 4, a sliding contact body 14 that comes into contact with the circumferential side edge of the unlocking operation hole 11 and slides on the elastic lock body 9 is formed to protrude. .

The size of the reel 1 shown in the embodiment differs depending on the material to be wound and its unit length (length of one turn). Has a diameter of about 300 to 600 mm and a thickness of about 3 to 10 mm, and the size of the drum body 3 is 100 to 250 mm in diameter.
mm and a width (length in the axial direction) of about 40 to 180 mm. Of course, this numerical value is a numerical value indicating the size of a general reel, and there is naturally a numerical value smaller or larger than this.

In order to assemble the reel 1 constructed as described above, in FIG. 4, hooks 8 formed on the upper and lower surfaces of the drum 3 are engaged with engaging holes 10 of the upper and lower flanges 2.
Into the flange body 2 with respect to the drum body 3,
2 are rotated clockwise, and each hook body 8.
May be engaged with the edge of. This will be described in more detail with reference to the relationship between the upper flange body 2 and the drum body 3 in FIG. 4. Inserting the hook bodies 8a, 8b, 8c... Into the engagement holes 10a, 10b, 10c. Then, the flange body 2 is rotated clockwise in the drawing, and the hook bodies 8a, 8b,
8c are engaged so as to overlap the edges of the respective engagement holes 10a, 10b, 10c.

At this time, the elastic lock body 9 is successively shown in FIG. 7 (for ease of understanding, FIG. 7 shows the lower sliding body 14 on the lower side of the lower flange body 2 in FIG. 4).
The relationship between the hook body 8 and the elastic lock body corresponding thereto is shown. When the hook body 8 is inserted into the engagement hole 10 of the flange body 2 as described above, the sliding contact body 14 of the flange body 2 and the elastic lock body 9 is located at the position shown in FIG. 7A, and when the drum body 3 is rotated clockwise in FIG. 7, the elastic lock body 9 is rotated as shown in FIGS. 7B and 7C. When the sliding contact body 14 is forcibly moved downward in the drawing while being in contact with the inclined side surface 14a of the sliding contact body 14 and relatively moving, and the sliding contact body 14 passes through the elastic lock body 9 and the contact between the two is released. As seen in d), the elastic lock body 9 moves onto the unlocking operation hole 11 by its elastic restoring force, and the relative movement of the two stops. In this state, if the flange body 2 tries to rotate in the reverse rotation direction, the elastic lock body 9 comes into contact with the rear end face 14b of the sliding contact body 14 to prevent reverse rotation.

In this manner, the drum body 3 and the flange bodies 2, 2 are prevented from moving in the axial direction by the engagement of the hook bodies 8, and are elastically locked from moving in the direction in which the hook bodies 8 come off. The body 9 is prevented from contacting the rear end face 14b of the sliding body 14, and the engagement of the hook bodies 8 is maintained. Therefore, as shown in FIG.
Can be formed.

When the reel assembled in this manner is disassembled when not in use, as shown in FIG. 7E, an arbitrary tapered tool such as a driver is externally inserted into the unlocking operation hole 11. Or a dedicated tool for disassembly is inserted, the elastic lock body 9 is moved in the direction of the arrow, the contact state with the sliding contact body 14 is released, and the flange body 2 is rotated in the opposite direction to engage with the hook bodies 8. The engagement with the holes 10 may be released, and the holes 10 may be relatively moved in the axial direction and separated.

When the hooks 8 are assembled, the outer end surface thereof is higher than the projecting height of the rising ribs 12 formed for reinforcement on the outer peripheral surface of the flange body 2 and the peripheral portion of the window hole 15. Is also set to a thickness that does not protrude outward. In this way, when the reels are stacked, the hooks 8 do not protrude outward and become an obstacle.

The reel 1 assembled in this manner includes:
A required long object to be wound is wound on the outer peripheral surface of the drum body 3 and used. In this reel 1, a plurality of types of flange bodies 2 having different outer diameters and a plurality of types of drum bodies 3 having different lengths in the axial direction are manufactured in advance. Many types of reels having different widths can be obtained. In addition, the empty reel after unwinding and using the wound material is disassembled as described above,
When transported for reuse as in the case of the flange bodies 2 and 2 and the drum body 3 before assembly, the transport can be performed in a small bulk state.

FIGS. 8 and 9 show a second embodiment, in which the elastic lock body 9 has sufficient strength in the width direction and can sufficiently prevent movement in the reverse rotation direction. In spite of this, the tip portion on the swinging side is made smaller so that the contact portion of the flange body 2 with the sliding contact body 14 is made smaller, so that the rotation angle during assembly is made smaller. In other respects, the structure is the same as that of the first embodiment, and the description is omitted.

As described above, it is sufficient that at least two hook bodies 8 according to the present invention are formed on each opening surface of the drum body 3, and the number thereof is not particularly limited.
Further, in the elastic lock body 9, if at least one elastic lock body 9 is formed on each opening surface of the drum body 3, it can function as a reverse rotation prevention.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to only the structures of the embodiments, but has the above-mentioned constitutional requirements according to the present invention, and The present invention achieves the object of the present invention and can be appropriately modified and implemented within the range having the following effects.

[0025]

As is apparent from the above description, in the reel according to the present invention, the flange body and the drum body are manufactured separately, and both are assembled and connected and disassembled and separated via the connecting portion. The structure of the connecting portion between the two hooks is formed by projecting outward from both axial edges of the drum body and forming a hook portion for engagement at the tip thereof and the radial direction of the drum body. The hook portion is engaged with an engagement hole formed in the flange body. In this engaged state, the elastic lock body is engaged with the unlocking operation hole of the flange body. At the position, it comes into contact with the sliding contact body, the hook body opposes the large outward surface pressure applied to the inner surface of the flange body, and the elastic lock body prevents the relative rotation of the flange body and the drum body in the opposite direction. Blocking Even if a large surface pressure is generated on the inner surface of the flange by the wound material wound on the reel, the plurality of hooks can surely oppose each other. Since the relative rotation can be reliably prevented by the elastic lock body in the direction orthogonal to the elastic direction of the elastic lock body,
The assembled state can be reliably maintained. In addition, even if assembly and disassembly are repeated, a reel having less durability and excellent durability can be obtained.

Further, the reel according to the present invention can selectively assemble a plurality of types of flanges having different outer diameters and a plurality of types of drums having different widths, thereby assembling and disassembling a plurality of types having different flange diameters and flange intervals. It is possible to obtain a possible reel, and it is only necessary to form an engaging hole and a fitting hole in a flange body and to form a hook body and an elastic lock body in a drum body in manufacturing. It also has the advantage that it can be easily and efficiently manufactured with a relatively simple molding die without requiring a simple molding die.
