Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a method for packaging electric wires, particularly reels wound with wires (e.g. enameled wires).

Electric wire is generally manufactured by being wound on a reel attached to a manufacturing machine, and when used, it is unwound from the reel. Electric wire wound on a reel is exposed to the outside and is easily damaged during transportation, so it must be completely wrapped. Conventionally, this packaging was done either by storing the reel in a cylindrical container with a bottom and fixing the lid, or by placing the reel on a plate-shaped base (called a bottom plate) and placing the reel in a cylindrical container with a bottom. This was done by placing a shaped container upside down and fixing it to the bottom plate. However, with this method, the container is easily damaged by the impact of the reel moving internally during transportation, and the container, lid, and bottom plate must be made strong, and the reel must be lifted above the ground to be stored. Or you need to put it on the bottom plate. Recently, the unit weight of the reel has become larger in order to improve usage efficiency and transportation efficiency, and the Japanese standard (C) specifies PT60 (wire weight 60Kg) PT100 (wire weight 100Kg) PT270
If the reel is heavy (270 kg), it cannot be lifted manually and must be lifted by mechanical power.

The present invention is directed to the use of the larger-diameter flange of a winding reel for electric wire, particularly a tapered reel for vertical take-up (having a tapered body and the upper and lower flanges having different diameters), as the bottom plate of a packaging container. The purpose of this invention is to eliminate the drawbacks of the conventional packaging containers and reduce costs.

That is, after winding an electric wire onto a take-up reel, especially a tapered reel for vertical take-up, place the reel vertically with the large side flange facing down, and place a wire on top of it with an inner diameter or an outer diameter close to the diameter of the lower flange. This method of packaging a reel for electric wire is characterized in that a cylindrical container having a bottom is placed on top, and the periphery of the open end of the container is fixed to the outer periphery of the lower flange.

The method of fixing the lower flange and the packaging container of the present invention is as follows: (a) A plurality of screw holes or pin holes are formed on the outer periphery of the flange, holes are made at positions corresponding to the holes at the open end of the container, and screws are inserted. Or fix it with a pin.

(b) A protrusion is provided on the outer periphery around the open end of the container, and the protrusion and the outer periphery of the lower flange are both tightened and fixed with a steel band having an arcuate cross section. (c) Below the reel A convex part is provided in the center of the tsuba on the opposite side from the wire winding part, and a space is created between the periphery of the lower tsuba and the floor, and a pin is passed through the hole made at the open end of the container into the space. (d) Make a container from an elastic material, make an annular groove inside the open end, insert the container from above, and fit the groove and the lower flange to secure it ( e) Attach a plurality of elastic fasteners to the outer periphery of the open end of the container, and fit and secure the fasteners to the lower flange of the reel. A groove is provided, and a pin is provided inside the open end of the container, the container is inserted from above, and the pin is inserted into the groove from the bent part of the L-shaped groove to rotate the container and fix the container to the reel. There are ways to do this.

In this case, when the lower flange and the container are fixed, if a ring of elastic material such as a sponge is attached to the inner surface of the cylindrical container at a position that corresponds to the upper surface of the lower flange, the loose electric wire of the reel will fall into the gap and get caught. This can prevent scratches or extreme bending from occurring.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an embodiment of the present invention, and FIG. 2 is a drawing showing details of a container fixing method of the embodiment. An electric wire 2 is wound around a reel 1.
A plurality of screw holes 5 are formed on the outer periphery of the lower flange 4. A hole is made in the periphery of the cylindrical lower end of the container 3 at a location corresponding to the screw hole 5 of the reel lower collar 4. This container 3 is placed over the reel 1, and a washer 7 is placed on the outside of the hole. Then, fix the lower end of the container 3 to the lower collar 4 of the reel with the screws 6. In this case, as shown in FIG. 3, a plurality of pin holes 9 having enlarged portions are formed on the outer circumference of the lower collar 4 of the reel.
An elastic pin 8 with a tip split into 2 to 4 pieces may be pushed through the hole in the container and fixed. Fourth
The figure shows another embodiment in which a protrusion 9 is provided on the outside of the lower end of the cylindrical container 3, and a steel band 10 with an arcuate cross section is used to connect the protrusion to the lower collar 4 of the reel. The reel is wound so as to surround the periphery thereof, and the container is fastened to the lower collar of the reel by a fastener 11 shown in FIG. In addition, as shown in FIGS. 5 and 6, an annular groove 12 is formed in the lower collar 4 of the reel.
Alternatively, a structure may be adopted in which a notch 13 is provided and the cylindrical container 3 is fitted into the groove or the notch. In this case, if a ring 14 made of an elastic material such as a sponge is attached to the inside of the cylindrical container in contact with the lower flange, as shown in FIGS. You can prevent this from happening. Of course, this elastic attachment can also be used in other embodiments of the invention.

Particularly when the weight of the reel is large and the strength of the lower flange is required, a protruding portion 15 is provided on the lower flange as shown in Fig. 8 to create a gap between the flange and the floor, and a hole in the lower end of the cylindrical container is formed. If the pin 17 is inserted and fixed, the strength of the collar will not be impaired.

Furthermore, if the weight of the reel is relatively light, the cylindrical container is made of an elastic material such as polyethylene or ABS resin, as shown in the embodiment shown in FIG. If it is, it is convenient because the container can be engaged with the lower flange of the reel simply by pressing the container from above. The same effect can be obtained even if a plurality of steel elastic fasteners 19 are attached around the lower end of the container, as shown in FIG.

FIG. 11 shows still another embodiment, in which a plurality of L-shaped grooves 20 are formed on the outer circumference of the lower collar 4 of the reel, and grooves 20 are formed on the inside of the lower end of the reel.
The container is fixed by lowering the container from above, fitting the pin 21 into the groove, and rotating the container.

In the above explanation, the diameter of the upper tsuba for vertical take-off is smaller than that of the lower tsuba, but in the case of Figs. The present invention can also be used for reels with flanges of the same diameter.

As is clear from the above description, according to the packaging method of the present invention, the lower collar of the electric wire reel is used as a part of the packaging, so the packaging is simple and robust.
Since no mechanical force is required for packaging, it has the effect of saving container materials.
