Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hoop band hooking device arranged at the final stage of a steel plate coil packing process, which prevents inner ring ring fitting in the inner hole of the steel plate coil from being displaced. Regarding

[0002]

2. Description of the Related Art A relatively thin steel plate coil such as a lomo
After being wrapped with paper, it is further wrapped with an iron plate, and then a plurality of hoop bands are hung on it to finish the packing. The main components of the iron plate packaging are the outer iron plate covering the outer peripheral surface of the steel plate coil,
The inner peripheral iron plate covers the inner peripheral surface, the circular iron plate covers both end surfaces, and the inner diameter ring fitted to the edge of the inner diameter hole.

The iron plate-wrapped steel plate coil 2 is further provided with a plurality of iron hoop bands 4 between inner and outer diameters thereof as shown in FIGS. Figure 1 for this
A trough-shaped band loop called a band chute 6 as shown in (C) is inserted into the inner diameter hole 7, the hoop band 4 is run in the band chute 6, and the hoop band 4 protruding from the opposite side is placed on the outer peripheral surface. It is hung around and overlapped with the feeding side of the hoop band 4 and fastened. The lower surface of the steel plate coil 2 is supported by two rotating rollers 8. The rotating roller 8 is rotated every time the hoop band 4 is laid horizontally in one direction to rotate the steel plate coil 2 by a predetermined rotation angle. Put 4 hoop bands.

[0004]

There is a step of tightening the hoop band 4 immediately before the both ends of the hoop band 4 are fastened. In this tightening step, the inner diameter of the hoop band 4 is changed as shown in FIG. 1 (D). The inner diameter ring 9 on the side for applying tension in the direction of pulling out from the hole 7 is strongly rubbed by the hoop band 4 moving outward from the inner diameter hole 7 during tightening,
It is often pulled out partially in an inclined state so that it can be pulled. When the hoop band 4 is continuously hung and the packing is finished without straightening the inner ring 9 thus displaced, moisture enters through the gap formed between the inner hole 7 and the inner ring 9 and the steel plate coil 2 May cause rust on the. In addition, the inner diameter ring 9 projecting outward
Interfere with the transportation of the steel plate coil 2.

An object of the present invention is to prevent the inner diameter ring from protruding during hooping of the steel plate coil.

[0006]

In order to solve the above-mentioned problems, the present invention presses an inner diameter ring against an end surface of a steel plate coil.
An inner diameter ring retainer having a compaction roller was arranged. That is, as described in the claims, in the hoop band hooking device that wraps and fastens the hoop band between the inner and outer diameters of the steel plate coil in which the inner diameter ring is fitted at both ends of the inner diameter hole, an inner diameter ring of the side tensioning the direction drawn from, for pressing the steel sheet coil end face compacting
An inner diameter ring retainer with rollers was provided.

[0007]

When the hoop band is tightened, one inner diameter ring tries to jump out, but since the inner diameter ring is pressed against the steel plate coil end surface by the inner diameter ring retainer,
The hoop band can be hooked without lifting the inner ring from the end of the inner hole.

If a rolling roller is used for holding the inner diameter ring, the steel plate coil can be rotated while the rolling roller is in contact with the inner diameter ring to perform hoop banding one after another. On this occasion,
The pressure roller smoothly rides over the notch in the inner diameter ring, so that no unreasonable force acts on the inner diameter ring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1A, the air cylinder 10 is arranged in a direction perpendicular to one end surface of the steel plate coil 2. The air cylinder 10 is supported by a support member (not shown) of the band chute 6. An inner diameter ring pressing plate 12 is arranged at the tip of the piston rod 10a of the air cylinder 10. In order to hold the inner ring 9 without any gap,
Front surface of the pressing plate 12 (surface facing the end surface of the steel plate coil 2)
It is advisable to stick an elastic sheet (not shown) such as urethane. Further, in order to deal with the unevenness of the surface of the inner diameter ring 9, a spring may be interposed between the piston rods so that the inner diameter ring 9 is pressed at a constant pressure without excess or deficiency.

The pressing plate 12 is always waiting at the retracted position separated from the end surface of the steel plate coil 2 by a predetermined distance, and at the final tightening step (step of FIG. 1D) for hooking each hoop band 4. Only the end face of the steel plate coil 2 is abutted, and the portion of the inner diameter ring 9 against which the hoop band 4 abuts is pressed down. If you tighten the hoop band 4 in this state, the hoop band 4
The inner ring 9 and the inner ring 9 rub against each other to exert a force for pulling the inner ring 9 to the outside. However, since the inner ring 9 is pressed against the end surface of the steel plate coil 2 by the inner ring pressing plate 12, no displacement occurs.

When the winding of one hoop band 4 is completed, the inner diameter ring pressing plate 12 is once retracted, the rotating roller 8 is rotated to rotate the steel plate coil 2 by a predetermined rotation angle, and the next hoop is rotated in the same manner. Put 4 bands.

Here, as the inner diameter ring retainer, the retainer plate 12 is used.
Instead of this, the compaction roller 14 of the present invention as shown in FIGS. 2A and 2B is used . A plurality of compaction rollers 14 may be arranged, or only one compaction roller 14 may be arranged close to a place where the hoop band 4 passes. The rotating shaft of the pressure roller 14 is supported by the tip of the piston rod 10a of the air cylinder 10. When the rolling roller 14 is used, the steel sheet coil 2 can be rotated while rolling the plural points of the inner diameter ring 9, so that the efficiency of the hoop band 4 hanging operation can be improved. Further, the inner diameter ring 9 is usually provided with a notch 1 having a predetermined width in order to avoid a grip bending portion at the winding start end of the steel plate coil 2.
6 is formed, but the compaction roller 14 has the notch 1
It is convenient because you can get over 6 smoothly.

If the inner diameter ring pressing plate 12 of FIG. 1 (A) is slightly inclined in the rotating direction of the steel plate coil 2, the same action as the pressure roller 14 can be obtained. That is, instead of bringing the entire surface of the holding plate 12 into contact with the inner diameter ring 9 with a uniform pressure, the holding plate 12 is slightly tilted, and is strong at the upper end of the holding plate 12 and weak at the lower end in FIG. By abutting on the inner diameter ring 9, the steel plate coil 2 can be smoothly rotated in the arrow direction while the pressing plate 12 is abutting on the inner diameter ring 9.

[0014]

As described above, according to the present invention, since the inner diameter ring retainer is provided, it is possible to reliably prevent the inner diameter ring from being displaced during the hoop banding process.
