Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reel used for winding various flexible filaments such as tubes, hoses, electric wires, cables and filaments.

[0002]

[Prior Art]

 The flexible filament reel has a structure in which a collar plate is attached to both ends of the winding drum, and has been widely used than before. The basic shape of the reel has not changed much even today. Due to reasons such as space, weight during transportation, and processing of unnecessary reels, the material is changing from conventional plastics to cardboard and corrugated cardboard, which are easy to dispose of and inexpensive at a raw material cost. Yes (Jitsuko Sho 58-27888, etc.). Most paper reels require a winding cylinder and a collar plate, which are formed separately, when it is necessary in a factory that manufactures flexible filaments, mainly because of storage space. It is assembled by gluing each time.

[Problems to be solved by the device]

 By the way, in the case of a tube made of a thermoplastic resin that is soft and easily deformed, such as a polyurethane tube, if the tube immediately after extrusion molding is wound as it is on a small diameter reel, shrinkage or deformation with time tends to occur in the tube. Therefore, it is generally performed that a tube is wound around a reel having a large winding diameter in advance, left for a predetermined time, and then subdivided from a large reel to a paper reel having a small diameter. In this case, the tube had to be rewound on a small-diameter reel attached to the winder, resulting in poor productivity. For this reason, recently, it has been considered to bundle the tubes in a coil shape without winding them, and attach the remaining collar plate to the reel while mounting the bundle on a reel with only one of the collar plates attached. However, there is a problem that the workability is not necessarily good because the adhesion of the winding drum and the collar plate is unexpectedly troublesome and there is a risk that the tube will be soiled with an adhesive.

In view of such problems of the conventional technology, the present invention provides a paper reel that can be easily assembled without using an adhesive and is applicable to various filaments. To that end.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, a reel according to the present invention has a plurality of tongues extending at predetermined intervals at opposing positions on two parallel sides of a strip, and a fold line parallel to the tongues is interposed therebetween. A support member that is bent to form a polygonal tubular body, a cylindrical winding cylinder that is externally fitted to the support member, and one tongue piece of the support member from the inside while the winding cylinder is externally fitted. A pair of collar plates with a plurality of pairs of long holes for receiving the front end portions of those tongues projecting outward and bending and receiving them from the other long holes The configuration.

[0006]

[Action]

 In the reel having such a structure, a plurality of tongue pieces projecting at both ends of the supporting member which is bent into a tubular shape are respectively inserted into the pair of long holes of the collar plate, so that the supporting member and the collar plate are securely coupled. be able to. Here, the cylindrical winding drum around which the various filaments are wound is fitted onto the support member with the flange plate attached to one end of the support member, and the remaining flange plate is joined to the support member to lock it. To be done. That is, since this reel is assembled by inserting operation without using an adhesive or a tool, it is easier to assemble than a conventional reel, and in particular, a linear body bundled in a coil is assembled into a reel. It is convenient when wearing while.

[0007]

【Example】

 Next, the reel of the present invention will be described in detail with reference to the drawings, but of course the present invention is not limited to the embodiments, and modifications can be made within the technical concept of the present invention.

FIG. 1 is an exploded perspective view showing an embodiment of a reel according to the present invention. The reel 1 is composed of a support member 2, a winding drum 3, and a pair of collar plates 4 and 4 in an assembled state. 2 has a shape shown as a front view in FIG.

In the above structure, the support member 2 is made of paper products such as corrugated cardboard or other cardboard, and as shown in FIG. 3 in detail, the four long sides 2B of the strip 2A which are parallel to each other face each other. The tongue pieces 2C are integrally provided at a predetermined interval, and the band plate 2A is further provided with folding lines 2D at positions connecting the respective side ends of the tongue pieces 2C facing each other. Then, by bending along this folding line 2D, an octagonal cylindrical body that is substantially square is formed. In the embodiment, the length of the strip 2A is made longer so that the short sides 2G are overlapped with each other. Further, the tip end portion of each tongue piece 2C serves as a trapezoidal hooking portion 2E, and each of these tongue pieces 2C is provided with two folding lines 2F parallel to the long side 2B.

A paper tube made of thick paperboard is used for the winding cylinder 3, the inner diameter of which is fitted to the outside of the support member 2 bent into a tubular shape, and the length is a short length of the support member strip 2A. It is slightly shorter than the side 2G. If necessary, at least one position on the circumferential surface of the winding drum 3 may be provided with a through hole or a notch for inserting and locking the tip of the filamentous body when the filamentous body is wound up.

Further, as shown in FIG. 1, each of the pair of collar plates 4 is formed in a circular shape by using corrugated cardboard or other thick board like the supporting member 2, and a through hole 4 A is formed in the center thereof. A pair of long holes 4B, 4C which are opened and receive the tongue piece 2C of the support member 2 are formed outside the through hole 4A at four 90-degree intervals on four concentric circles. Here, the four elongated holes 4C located on the outer side correspond to the tongue pieces 2C at the four corners of the supporting member when formed into a tubular shape. The lengths of these long holes 4B and 4C correspond to the width of the portion of the supporting member excluding the hooking portion 2E of the tongue piece 2C. Although not provided in the collar plate 4 of the embodiment, it is of course possible to provide a through hole for hooking the leading end portion or the trailing end portion of the filamentous body, like the winding drum 3.

Next, a method for assembling the reel will be described with reference to FIGS. 4 and 5. First, the plate-shaped supporting member 2 is bent along a folding line 2D parallel to the short side 2G of the strip 2A to form an octagonal cylinder (FIG. 1). Then, the four tongue pieces 2C projecting to the one end side of the tubular supporting member 2 are inserted into the long holes 4C of one of the collar plates 4, and the tongue pieces 2C are inserted through the folding lines 2F. After being folded back toward the center of the, the hook portion 2E formed at the tip portion is bent and inserted into the elongated hole 4B on the inside. As a result, the support member 2 and the collar plate 4 are joined (FIG. 4). In this state, the winding drum 3 is externally fitted to the support member 2 (FIG. 5), and the other collar plate 4 is similarly coupled, whereby the assembly of the reel 1 is completed.

The reel 1 described in the above embodiment has a structure in which the winding drum 3 is rotatable without being fixed to the support member 2 and the collar plate 4. Therefore, when pulling out the filamentous body wound on the reel 1, it is sufficient to place the reel 1 at the foot and pull it as it is. Therefore, the reel is much more convenient to use than a conventional reel that is pulled out one by one in a state in which the reel is turned down, or is attached to a reel stand and pulled out.

In the above embodiment, an example in which the winding drum 3 is rotatable with respect to the support member 2 and the collar plate 4 has been described, but this reel is attached to the winder and continuously molded. When the filamentous body is wound directly onto this reel, as a slip prevention means, for example, a pin is inserted from the outside of the collar plate 4 into the tube wall of the winding drum 3, or the short side of the winding drum 3 and the support member 2. The lengths of 2G may be the same and may be fixed by friction with the collar plate 4. Further, if the shape of the supporting member is at least a triangular or more cylindrical body, there is no functional problem, and the number of tongues 2C can be changed.

[0015]

[Effect of the device]

 As described above, the reel according to the present invention can be easily assembled by inserting operation without using an adhesive or a tool.Therefore, while the reel is assembled, the linear body bundled in a coil is mounted. It is particularly convenient when doing. It is also possible to make the winding drum rotatable with respect to the guard plate. In this case, the filamentous body can be smoothly pulled out without using the reel stand, and its practical effect. The fruit is extremely large.
