DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a pair of left and right flange members, a drum member provided at an intermediate portion sandwiched between the two flange members, and a shaft hole formed at a central portion. A flexible long object such as tape, wire, chain, etc. is wound around and transported, and a support shaft is passed through a shaft hole at the center of use at the site of use, and the wound long object is sequentially wound. The present invention relates to a distribution reel used for feeding and using.

[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 the case of a so-called flat strip-shaped long rolled object (conveyed object) such as a film or a tape, the winding surface of the drum body on which the wound conveyed object is wound first has a smooth surface. If not, due to the winding pressure load of the sequentially wound conveyed object itself, and the time lapse from winding to unwinding use,
A situation occurs in which a portion at the beginning of winding, that is, a part of layers at the beginning of winding, is deformed by unevenness of the drum body.

On the other hand, as shown in FIGS. 9 and 10, the conventional reel 11 has a triangular mountain-like projecting end face of a drum body 13 around which an object to be carried around a flange body 12 is wound. The other end surface of about one-half circumference is formed on the flat surface 15, and the triangular ridge-shaped protrusion 14 and the flat surface 15 of the drum body of the other flange body are brought into contact with each other. Then, ultrasonic vibration was applied from the outside to melt and weld the triangular ridge-shaped protrusions 14. Further, in such a means, since the bonding strength is insufficient, another inner cylinder 16 is formed on the inner peripheral side, and a number of connecting spokes 17 are provided between the drum body 13 and the inner cylinder 16. Forming these inner cylinders 1
6 and the connecting spokes 17 are also formed on the end faces thereof in the form of triangular mountain-shaped protrusions 18 for the portions corresponding to about one-half.
The end face of the other half portion was a flat surface 19.

[0004]

Therefore, in this kind of conventional distribution reel, the molten resin melted at the time of welding easily protrudes to the outer peripheral surface of the drum body 13 and it is difficult to obtain a smooth drum surface. There was a problem that. Further, the bonding area was small and the bonding strength was not sufficient. In particular, once the molten resin has protruded onto the drum surface, the operation of removing the molten resin between the narrow opposed flange bodies 12, 12 is difficult and time-consuming. Further, as means for increasing the bonding area and increasing the bonding strength, the inner cylinder 16 and a large number of connecting spokes 17 are provided, so that the manufacturing die becomes complicated, and it is not easy to improve the production efficiency. Wasted, which hindered a reduction in production costs.

Accordingly, the present invention focuses on the problems of such a conventional distribution reel, and in order to solve such problems, the molten resin is formed on the drum without complicating the structure. An object of the present invention is to provide a distribution reel having a structure that hardly sticks out on the surface and that can easily perform reliable bonding.

In this embodiment, the flange body 2 has a flat plate shape, and has a through shaft hole having a projecting portion 41 projecting in three directions for inserting a support shaft during rotation at the center thereof. An arc-shaped drum body 3 protruding toward the inner surface side of the flange body 2 is integrally formed on the outer periphery of the drum body 3 around the center. Thus,
The left and right drum bodies 3 and 3 are butted and bonded together to form the reel 1. The flange body 2 thus formed is a molded product formed entirely of a synthetic resin material.
The small round hole 5 close to the central shaft hole 4 shown in FIGS. 1 and 3 is a through hole for inserting a rod or the like and rotating it, and has four large fan-shaped window holes 6 on the outer periphery. Are through holes for visually checking the winding state of the wound object. Reference numeral 37 in FIG. 3 denotes a reinforcing rib of the drum body 3.

As shown in FIG. 3, the drum body 3 of this embodiment has cut portions 34 formed at four locations in the circumferential direction, and is divided into four portions along the axial direction. a body, the end face 31 in the axial direction, as shown in the enlarged view of FIG. 3, the fitting convex strip 32 and Hamago凹groove 3
3 are alternately formed in the circumferential direction. As shown in FIG. 5, the two portions 32 and 33 are formed in a partial arc shape having a trapezoidal cross section, and are formed to have substantially the same shape and size so as to fit each other. These are formed by projecting or recessing in the widthwise intermediate portion of the end surface 31 while leaving small flat surfaces 35, 36 on the outer peripheral surface side and the inner peripheral surface side of the end surface 31.

With such a shape, in the drum body 3 of the embodiment, as shown in FIGS. 4 and 5,
Than the projection height h from the end face 31 of the Hamagototsujo 32, slightly the recess depth H from the end face 31 of the Hamago凹groove 33 becomes deeper about 0.5mm~1.0mm is substantially It is formed as follows. The two flange bodies 2 thus formed,

The initially inclined surfaces each other and the convex ridge 32 and the concave groove 33 at the time of welding is melted by abutment, the molten resin gradually concave
It is pushed into the space at the bottom of the groove 33, and a part thereof moves to the flat surface 31 side. Thus, the state does not lead to by molten resin between the ridges 32 and the concave groove 33 was melted ends the application of ultrasonic vibration in a state of reaching the flat surface 31, reaches the outer peripheral surface of the drum body 3 Complete bonding is performed.

The size of the reel 1 in this embodiment varies depending on the material to be wound and its unit length (length of one roll), but the size of the flange body 2 is 300 to 600 m in diameter.
m, the thickness is about 2 to 5 mm, and the size of the drum body 3 is 100 to 200 mm in diameter and 4 to 6 m in thickness.
m, and the protrusion length is about 40 to 100 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.

As described above, the reel 1 shown in the first embodiment is composed of two flanges 2 and 2 and a butt drum 3 formed therebetween, as shown in FIG. Thus, the drum body 3 has a structure in which the drum body 3 is joined and integrated at an intermediate portion in the axial direction. Thus, this reel 1
Is a slot 34 for inserting the leading end of a wound object, which is linearly continuous over the entire width in the width direction formed by facing the cut portions 34.
A is formed on a reel. However, since the slot 34A is not always necessary, it goes without saying that the drum 3 without the cutout 34 may be used.

In the second embodiment shown in FIG. 6, a flange body 3a having a short protruding length is provided on the drum body 3 of one (left side in the figure) flange body 2 shown in the first embodiment. 2a is an embodiment of the reel 1 in which the overall width of the drum is formed to be smaller than that of the first embodiment. Needless to say, the flange body 2a in FIG.
Are connected to each other, a reel having a further narrow axial width can be obtained.

The embodiment shown in FIG. 7 is different from the second embodiment in that the flange body 2 shown in the first embodiment is not shown.
This is formed on a reel 1 having a large width in the axial direction by connecting and connecting a flange body 2b having a long protrusion length drum body 3b to the (right side in the figure). Needless to say, also in this case, FIG.
If the two flange members 2b are connected in opposition, a reel having a wider axial direction can be obtained.

In the embodiment shown in FIG. 8, a pair of flange bodies 2 and 2 are formed to be substantially flat, and these flange bodies 2 and 2 and the drum body 3 are separately formed. This shows an embodiment in which the reel 1 is formed by members. The reel 1 of this embodiment has a flange 2
A drum continuously arranged expected circumferential position of the inner surface side of, on the opposite end surfaces of the drum body 3, the fitting convex strip 3 described in the first embodiment
It shall is formed with the 2 and Hamago凹grooves 33, by disposing the drum body 3 between a pair of flanges 2, 2, integrally tripartite or individually melted adhesive It is integrated. Even in this manner, the distribution reel according to the present invention can be formed.

The drum body 3 shown in the first embodiment is
As described above, the cut portions 34 are formed at four places at appropriate intervals in the circumferential direction of the drum body 3. However, by providing the cut portions 34, the cut portions 34 are provided. This is convenient because the leading end of the entangled object (transported object) can be inserted into and locked at 34. Therefore, the number does not need to be four, but may be formed in at least one place. However, as described above, the notch 34 is not always necessary.

The embodiments which are considered to be representative of the present invention have been described above. However, the present invention is not necessarily limited to 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.
