Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel, and more particularly to a wooden reel for winding and shipping wire materials such as electric wires and cables.

[0002]

2. Description of the Related Art Conventionally, a wooden reel (drum) has been used for winding a wire material such as an electric wire or a cable and shipping it as a product.

A conventional wooden bobbin is composed of a cylindrical winding drum portion and a pair of disc-shaped brim portions fixed to both ends thereof, and each brim portion has a plurality of elongated rectangular shapes. The collar plates are arranged side by side without any gaps, and if necessary, they are stacked in the thickness direction so that the arrangement directions are orthogonal to each other, and are integrally fixed by nails or the like.

[0004]

However, in such a conventional reel, since a plurality of elongated rectangular collar plates are arranged and overlapped with each other to form a collar portion,
There is a problem that not only the material cost is required because the timber having a predetermined length or more is required, but also it is difficult to cut out (plank) from the material timber.

The present invention has been made in order to solve these problems, and provides a reel that can reduce the amount of wood used to manufacture the collar portion, save wood resources and reduce costs. The purpose is to do.

[0006]

SUMMARY OF THE INVENTION A reel according to the present invention is a reel having a pair of disc-shaped collars fixed to both ends of a cylindrical reel, and a groove is formed at each end in the width direction. A plurality of rod-shaped metal members having a V-shaped cross section are radially arranged from the center, and a wooden collar plate having a predetermined shape is provided between the rod-shaped metal members of the metal frame. It is characterized in that the flange portions are configured by disposing both ends of the plate by fitting them into the concave grooves of the rod-shaped metal member.

In the reel according to the present invention, a metal frame in which a plurality of rod-shaped metal members having a V-shaped cross section are arranged radially from the center, and a plurality of wooden guard plates inserted between these metal members. Since the collar portion is formed by combining and, the strength is greater than that of the conventional collar portion formed only from the wooden collar plate. Therefore, the thickness of the collar portion, that is, the thickness of the wooden collar plate can be made thinner than in the conventional case, and the amount of wood used can be significantly reduced.

Further, as the collar plate, a collar plate having a small area in which the shape (fan shape) of the gap between the rod-shaped metal members is divided in the direction orthogonal to the radius can be used, so that the end material can be effectively used. It is possible to manufacture a guard plate by utilizing it, and it is possible to reduce the wood resources and the cost. Furthermore, since the collar portion can be disassembled, the material wood can be easily collected.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partially cut front view showing an embodiment of a reel according to the present invention, and FIG. 2 is a plan view of a collar portion which is a main part of the embodiment. Further, FIG. 3 is an enlarged view of an AA cross section in FIG. 2.

As shown in the drawing, the reel of the embodiment comprises a wooden winding barrel 1 having a cylindrical shape and a pair of disc-shaped brim portions 2.

In each of the collar portions 2, a plurality of rod-shaped iron frames 5 having a V-shaped cross-section (for example, 6 pieces) having concave grooves 4 at both ends in the width direction around the central shaft hole of the shaft hole fitting 3, respectively.
Are radially arranged so as to form an equal angle with each other, and are fixed to the shaft hole fittings 3 by fixing bolts 6, respectively. In addition, between the iron frames 5 arranged in this manner, a wooden trapezoidal collar plate 7a and a fan-shaped collar plate 7b with a notched tip portion are provided. Are sequentially arranged so as to be formed, and are attached and fixed to the iron frame 5. That is, the collar plates 7 of the respective shapes described above are arranged such that the thinned portions 9 at both ends are fitted into the concave grooves 4 at both ends of the iron frame 5, respectively. Both ends are respectively fixed to the iron frame 5 with the holding screws 10.

The winding barrel 1 has a pair of disk-shaped members having a through hole for a reinforcing material or the like which will be described later in the center thereof and which are arranged to face each other at a predetermined interval (corresponding to the length of a cross plate which will be described later). Of the crosspiece receiving member 11 and a disk-shaped center plate 12 having an insertion hole for a reinforcing material or the like in the center and arranged parallel to the middle position of the crosspiece receiving member 11, and the crosspiece receiving member 11 and the center plate 12. A plurality of crosspieces 13 are arranged on the outer peripheral surface so as to straddle these, and arranged side by side without any gap therebetween.
The outer peripheral surface of 3 forms a cylindrical winding surface.

Then, at both ends of such a winding drum unit 1,
The above-mentioned collars 2 are arranged so that their central axes coincide with each other, and are fixed as shown below. That is,
A plurality of long bolts 14 for connecting between the corresponding iron frames 5 of the pair of flanges 2 are sequentially inserted through the long bolt insertion holes provided in the pair of crosspiece receiving members 11 and the center plate 12 of the winding drum unit 1, respectively. The long bolt 14 is tightened via the washer 15 so that the pair of collars 2 are connected to the winding body 1
It is strongly pressed and fixed to both ends of each. In addition,
In the figure, reference numeral 16 indicates a shaft fitting fitted in the central shaft hole of the shaft hole fitting 3, and reference numeral 17 indicates a reinforcing member laterally bridged between the shaft hole fittings 3 of the pair of flange portions 2.

In the winding frame of the embodiment constructed in this way, a plurality of iron frames 5 radially arranged around the central shaft hole of the shaft hole metal fitting 3 and mounted and fixed between them. Since the collar portion 2 is configured by the trapezoidal and notched fan-shaped collar plate 7, the strength is much higher with the same thickness as compared with the conventional collar part configured by stacking wooden collar plates side by side. large. Therefore, sufficient strength can be obtained even if the thickness of the collar plate 7 is thinner than the conventional one, and the amount of wood used for the collar plate 2 can be significantly reduced.

Further, since the trapezoidal plate 2 having a trapezoidal shape or a notched fan shape and a small area is used as the collar plate 2, it is possible to effectively use the mill ends, thereby saving the wood resources and reducing the cost. You can Further, in such a collar portion 2, the iron frame 5 and the collar plate 7 can be separated and disassembled, so that the material wood can be easily collected.

[0017]

As described above, according to the bobbin of the present invention, the amount of wood used as a material can be significantly reduced and, in addition, scraps can be effectively used. Further, since the brim can be disassembled, it is easy to recover the material wood.
