Description

[Detailed description of the invention] The present invention relates to a method for packing the inner circumference of a coil.

As shown in Fig. 1, the conventional coil packaging method involves inserting a cylindrical inner rust-preventing paper 2 along the inner periphery of the coil 1, covering the outer periphery with an outer-periphery rust-preventing paper 3; Both ends 3' of paper 3,
3' so as to cover the ends of the inner periphery rust preventive paper 2, and the ends of the inner periphery rust preventive paper 2 are wrapped with adhesive tape 4 and 4'.
Adhere and seal to paper 2.

Next, side protection materials 6 and 6', which have a through hole 5 in the center that is larger than the inner circumference of the coil 1, are applied to both sides of the outer periphery anti-rust paper 3.
For outer-periphery rust prevention, cover the outer periphery of the paper 3 with a cylindrical outer periphery protection material 7, bend both ends D and 7' along the outside of the side protection material 6°6', and form the side protection material 6°6. ′ is fixed.

Next, after inserting the cylindrical inner circumference protection material 8 into the inner circumference side of the adhesive tapes 4, 4', the cylindrical protection part 9 shown in FIG.
Edge protection material 11, 1 having a flange body 10 on the outer periphery of one end
The protective parts 9, 9 of 1' are inserted from both sides into the inner peripheral protective material 8 through the through holes 5 of the side protective members 6 and 6'. After that, a plurality of binding pads 12 are passed through both edge protection materials 11 and l1' and entwined with the outer periphery protection material 7 to form the edge protection material I.
11' to prevent it from falling off.

According to the conventional method, the edge protection material 11 is simply inserted with the cylindrical protection part 9, so there is a risk that the edge protection material 11 may fall off, and a cable tie 12 is required. Manual labor was absolutely necessary.

For this reason, the outer rust-proofing paper 3 is bonded to the inner rust-proofing paper 2.
Although it is necessary to perform rust prevention by adhering with 4.4', there is a drawback that a satisfactory seal cannot be achieved depending on the bending condition of the outer periphery rust prevention paper.

Furthermore, there is the disadvantage that considerable skill and labor are required when charging the edge protector, and the necessity of various manual operations has been a hindrance to mechanization of packaging.

The inventors of the present invention discovered that the above-mentioned conventional drawback was a problem with the sealing work using adhesive tape, and as a result of various studies to achieve complete sealing without using adhesive tape, they found that the inner periphery of the coil was coated with an inner rust preventive material. Cover the outer periphery of the paper with the outer periphery rust prevention paper, fold the end piece inside the inner periphery rust prevention paper, apply side protection material to both sides of the outer periphery rust prevention paper, and cover the outer periphery rust prevention paper. In packaging in which the side protection material is fixed with a protection material, the inner periphery protection material is applied to the inner periphery of the end piece, and an edge protection material having flanges on both sides and a tapered part at the tip is placed inside the inner periphery protection material. After that,
It has been discovered that good results can be obtained by expanding the tapered part toward the outer circumference and fixing it, and has proposed the present invention.

The method of the present invention will be specifically explained with reference to the embodiment shown in FIG. Cover with rust-proofing paper 3, and bend both end pieces 3 and 3' of this outer-circumferential rust-proofing paper 3 so as to cover the ends of the inner-circumferential rust-proofing paper 2, respectively.

Next, side protection materials 6, 6' having through-holes 5 are applied to both sides of the outer periphery anti-corrosive recording paper 3, a cylindrical outer periphery protection material 7 is placed over the outer periphery of the outer periphery anti-corrosion paper 3, and both ends 7, 7' is bent along the outside of the side protection members 6, 6' to fix the side protection members 6, 6'.

Next, a cylindrical inner periphery protection material 8 is inserted around the outer periphery of the bent end pieces 3', 3' of the outer periphery antirust paper 3 to form the end pieces 3'.

3, the edge protector 11.11 is inserted into the inner circumferential protector 8 from both sides.

As shown in FIGS. 4 and 5, the edge protection members 11 and 11' have a shape in which a cylindrical protection part 9 is provided continuously on the flange body 10, and a tapered part 13 is provided at the tip. The inclination angle θ of this tapered portion 13 is preferably about 5° to 40°.

The edge protection materials 11 and 11' are inserted until the flanges 10 abut against the side protection materials 6 and 6', respectively, as shown in FIG. 6(A). Thereafter, as shown in FIG. 6(B), the expansion push-in fittings 14 are inserted into the respective protection parts 9 of the edge protection members 11 and 11', and the tapered parts 13 are plastically deformed and expanded outward, thereby protecting the inner periphery. At the same time, sealing is performed between the end pieces 3', 3' of the inner circumferential rust-preventing paper 2 and the outer circumferential rust-preventing paper 3.

As shown in FIG. 6(A), the expansion push-in fitting 14 is as shown in FIG.
A tapered insertion section 15 is provided at the distal end, an enlarged section 16 with a circular cross section is provided at the distal end, and a support rod 17 is provided at the end surface. Then, the tapered insertion part 15 is easily inserted into the edge protection material 11, and by further pushing it, the expansion part 16 expands the tapered part 13- to the outer circumferential side.

More specifically, it is the same principle as the expansion and contraction principle of the winding shaft of a strip coil, for example.

After expanding the tapered portion 13 as described above, the tapered portion 1
The packing operation is completed by reducing the outer diameter of the expansion pusher 14 to the initial outer diameter and removing the expansion pusher 14.

An example of the metal fitting moving device 18 for the expansion push-in fitting 14 is constructed as shown in FIG. Sokuyoshi expansion push fitting 1
The support rod 17 of No. 4 passes through the inside of the cylinder 19, and the support rod 17 inside the cylinder 19 is provided with a piston portion 20. This cylinder 19 is fixed within a support tube 21, and the support tube 21 is fitted into a fixed tube 23 fixed on a truck 22 so as to be slidable in the direction of the arrow. And fixed cylinder 2
A rod 25 of a hydraulic cylinder 24 fixed on the support tube 3 is pivotally connected to a branch piece 26 fixed to one end of the support tube 21, and is moved by the support tube 21 by the drive of the hydraulic cylinder 24.

Further, on the coil 1 side of the support tube 21, there are support pieces 27.2 at the top and bottom.
7' is fixed, and presser rods 29 and 29' having presser members 28 and 28' attached to their tips are pivotally mounted.

This metal fitting moving device 18 moves the cart 22 along the rail 30, finely adjusts the position of the support tube 21 by driving the hydraulic cylinder 24, and inserts the edge protection material into the coil 1 using the holding members 28 and 28'. Hold down the collar body 10 of No. 11 so that it does not move. Thereafter, the cylinder 19 pushes out the support rod 17, and the expansion pusher 14 expands the tapered part 13 of the edge protection material 11 toward the outer circumference as described above.

The present invention is configured as described above, and the edge protection material 11 is provided with a tapered part 13 at the tip, and by expanding this toward the outer periphery, the edge protection material 11 is brought into close contact with the inner periphery protection material 8 and simultaneously released. The end pieces 3', 3' of the circumferential anti-rust paper 3 can be brought into close contact with the inner circumferential anti-rust paper 2 for sealing.

Therefore, the rust-proof paper can be reliably sealed and the edge protection material 11 is fixed without fear of falling off, so there is no need for cable ties as in the past, and packaging can be easily mechanized. Can be done.
