Field of the Invention The present invention relates to a metal strip coil which is wound by a take-up reel at the end of a production line in a field of iron making, for example, and whose outer peripheral surface is band-bound and fastened with a fastener. When transporting to a designated storage location or the next line and stacking two or more stacks and storing them, the upper and lower contact parts of the metal strip coil (band or fastener part)
Protectors for preventing pressing defects that prevent the pressing defects from being pressed against each other, such as contact defects of metal strip coils, local pressing defects, and overall deformation, and multi-stage stacking for preventing pressing defects using this protector. Regarding the method.

2. Description of the Related Art In the field of iron making, metal strips are manufactured in various lines such as a continuous rolling line, a continuous annealing pickling line, and a polishing line. The metal strip processed in each line is usually wound at the end of the line. After being wound up on a reel and formed into a metal band coil, the metal band coil bound on the outer peripheral surface of the metal band with a banding band and its fasteners can be directly transported and stored in a predetermined storage place with an overhead crane, a forklift, The work of transporting with an overhead crane via an automatic carrier and storing it in multiple stages was performed automatically or manually.

Conventionally, a metal strip coil stored in a predetermined storage place as described above has a structure as shown in FIG.
The metal strip coil 3 as the object to be protected is usually provided in one step on the mounting table 6 made of wood or synthetic resin, which is laid on the floor surface at a predetermined position and the mounting surface 6a is formed in a V shape or an arc shape. When allowed as needed, they were held and stored in a state of being stacked in two or three stages, but in particular, a binding band on the outer peripheral surface of the metal band coil 3 and a stopper for engaging both ends of the band. Are strongly pressed by the weight of the objects 3 to be protected that are stacked and located in the upper part, and therefore, the metal strip coils 3 between the objects 3 to be protected, and thus the surfaces of those metal strips are contacted with flaws or in the longitudinal direction. There is a problem that a pressing defect such as a local pressing defect having a generated pitch or a total deformation defect occurs. In particular, when such a pressing defect occurs in a metal strip having a gauge of 0.5 mm or less, it becomes difficult to perform surface polishing or re-rolling treatment for erasing the defect and repairing the metal strip. If a similar defect occurs in a thick metal strip, it cannot be repaired and is inevitably scrapped, which causes a problem that manufacturing yield and productivity are greatly reduced.

In such stacking and storing work, as shown in FIG. 8, for the object 3 to be protected, which is realized by the metal strip coil wound on the winding reel at the end of the line, for example,
The binding of the outer peripheral surface is stacked so that the fastener 5 of the binding band 4 is located above, or the metal strip coils 3 that are once bound are rotated so that the metal strip coils 3 do not come into contact with the fastener 5. Even when stacked in this way, it is inevitable that the binding band 4 itself is extremely pressed against each other to be protected 3, which causes a pressing defect.

The metal strip coil 3 is used in the production line.
When processing and manufacturing a sheet with a thickness of 0.5 mm or less, a binding band made of a relatively thin resin material may be used for binding, but the binding band is still located in the upper part. Due to the weight of the protected object 3 being pressed, a pressing defect was generated between the protected objects 3.

Further, as a means for preventing the pressing defects between the protected objects 3, as shown in FIG. 5, the elastic piece 1 should be mounted on the outer surface of the protected object 3 in a storage place to perform stacking work. Since it had to be done, it was difficult to operate the overhead crane without an operator even though it was unsafe. A worker and an operator to operate the overhead crane were required. Further, when the protected object 3 is transported to the next process, it is an unsafe work, but the elastic piece 1 must be removed anyway at the storage location or the next process, which requires time and labor, and As shown in FIG. 7, for example, when the outer peripheral surface of the metal strip coil 3 wound on the winding reel at the end of the production line and mounted on the coil carriage is bound by the binding band 4 and its fastener 5, Band coil 3
When the elastic body piece 1 was attached to the outer peripheral surface of the sheet and adhered with the tape 7 and sequentially transported to each predetermined storage location, an adhesion mark remained on the outer peripheral surface of the metal strip coil 3 and further polishing oil or rolling oil adhered thereto. The metal strip coil 3 has a drawback in that it is difficult to bond, there is a risk of peeling off during transportation, and the workability is extremely poor.

In the physical distribution of the metal strip coil 3 as a protected object which is transported and stored from the take-up reel at the end of the manufacturing line to the storage step, the narrow storage area is not limited to one stage, but 2-3 When the entire physical distribution is automatically or unattended by substantially unattended while holding it in layers and storing it effectively in three dimensions, the occurrence of pressing defects between the protected objects 3 is very large. It was a problem, and there was a great need for countermeasures to prevent it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of a protector for preventing a pressing defect, which is an embodiment of the present invention.
Is a side view and (c) is a plan view. The protector shown in FIG. 1 includes an elastic piece 1 and a plurality of magnets 2. The elastic piece 1 is made of a flexible material that can be bent and expanded and contracted.
A strip formed with a thickness of about 1 cm and a thickness of about 1 cm is used. On the other hand, the magnet 2 is formed of a thin strip having a thickness of several mm and has elasticity and flexibility, and is used on the surface of the central portion and both end portions of the elastic piece 1 in the longitudinal direction. As shown in the figure, the elastic piece 1 is attached over the entire width.

Examples of the material of the elastic piece 1 include woven or non-woven fabrics of natural fibers or synthetic fibers or blended fibers which are a mixture thereof, synthetic rubber or synthetic resin, and further belt materials. A material that is appropriately selected from the materials and formed into a single flat body having a predetermined shape or a flat bag-like body is used.

On the other hand, as the magnet 2, in addition to the strip shape shown in the figure, a magnet formed in a circular or rectangular thin plate piece made of a rigid body can be used. It is also possible to use an elastic magnet film piece formed by mixing powder and granules in a rubber film, and in the case of this elastic magnet film piece, it is not limited to local parts such as the central part and both end parts, The elastic piece 1 may be brought into contact with and integrated with the entire surface of the elastic piece 1.

FIG. 2 is a perspective view showing a state in which the protector shown in FIG. 1 is attached to a cylindrical body 3 as a protected object realized by a metal band coil. As shown in FIG. 2, the protector is provided in close contact with the surface of the metal strip coil 3 by covering the central portion around which the binding band 4 is wound with the top portion of the band 4 covered. In this case, each magnet 2 attached to the elastic piece 1 is magnetically attached to the metal band coil 3 and the binding band 4, and even if the binding band 4 is a non-magnetic material such as resin, the metal band coil 3 is If it is a magnetic material, it can be strongly adhered by magnetic attachment.

As the metal strip coil 3, for example, in the field of iron making, various metal rolls including work rolls such as a continuous rolling line, metal strip coils processed by a continuous rolling line and a continuous annealing pickling line, etc. ,
There is a multi-layered product such as steel pipes, and examples thereof include a cylindrical body, a cylindrical body, and a polygonal body that need to be stored so that a pressing defect that occurs between protected objects does not occur.

When the metal band coil is a non-magnetic material such as an austenitic stainless steel band coil, since the binding band used is generally made of a ferromagnetic material, the magnet 2 magnetizes the binding band. Since it can be worn, it is sufficiently applicable.

With respect to the protector, the elastic piece 1 is formed as a single piece or a two-piece piece divided in the width direction so as to easily correspond to the winding portion of the binding band, and further, the length in the longitudinal direction is small. According to the aspect of the corresponding tubular body, the tubular body 3 has a length or an area that can be interposed between the tubular bodies 3 or a position where they are pressed and contacted in a stacked state or mounted on a table. The length and area are set. Further, in comparison with the example shown in FIG. 1, it is also possible to adopt a form in which the elastic piece is attached and the lining is attached so that the magnet is not exposed.

Further, the magnet 2 is not only provided as a separate body from the elastic piece 1, but when the elastic piece 1 is made of a synthetic rubber or a flat body filled with synthetic resin, the magnet 2 is provided inside thereof. The powdery magnets may be dispersed and carried to form an integral structure. In the case of separate magnets, when the cylindrical bodies 3 are stacked in multiple stages, it is preferable that the magnets are made of a thin-walled soft material thicker than the binding belt so that they are not extremely pressed by their weight and do not generate pressing flaws. And, on the other hand,
In an example in which the elastic body pieces are scattered integrally, it is preferable that the magnet powder particles do not project when the elastic body pieces are compressed.

By the way, it is also possible to use a magnetic material instead of the magnet 2, and in this case, it is sufficient to magnetize the magnet before use, and when the tubular body or the binding band is magnetized. Can be magnetically attached as it is as a magnetic material.

To use the protector described above to stack the protectors in a multi-stage manner without causing a pressing defect, for example, the protector may be mounted on the tension reel or on the outer peripheral surface of the cylinder mounted on the carriage. After magnetically adhering, it may be operated so as to be sequentially transported to a storage place or the next line.

An example of attaching and detaching the protector at that time is shown in FIG.
And shown in FIG. In order to mount the protector, as shown in FIG. 3, a pair of suction plates 8 are used to vacuum-hold the protector at both ends, and the protector is lifted in an expanded state so that the magnetized surface of the magnet 2 faces downward. (See (a) of FIG. 3), the film is transferred directly above the cylindrical body 3, the vacuum suction is subsequently released, and the protector is dropped onto the cylindrical body 3. Since the protector that has dropped onto the cylindrical body 3 has an appropriate thickness and its own weight, it bends naturally along the cylindrical circumferential surface,
As a result of the magnets 2 at both ends being magnetically attached to the cylindrical body 3, the elastic piece 1 is attached in close contact with the cylindrical circumferential surface (see FIG. 3B).

On the other hand, as shown in FIG. 4, the protector magnetically attached to the tubular body 3 is removed by a pair of suction plates 8,
The magnets 2 are removed while sliding on the surface of the cylindrical body 3 by bringing the magnets 8 into contact with both ends where the magnets 2 are present and holding them by vacuum suction, and pulling up the suction plates 8 and 8 obliquely upward. Thus, the protector can be easily attached and detached by the mechanical operation.

[0033]

As described above, according to the present invention, the protector for preventing the pressing defect can be mounted on the predetermined surface portion of the cylindrical body which is the object to be protected by utilizing the magnetic force, and is securely and strongly fixed. Since it can be made and does not move, when multiple layers are stacked, the elastic piece is interposed at the contact position between the cylinders,
It is possible to prevent the occurrence of pressing defects. In addition, since it is a mounting method that uses magnetic force, it is possible to easily perform mechanized mounting without labor for mounting, and conversely, it is possible to mechanically mount and dismount, so that people can enter and leave the storage place. It is eliminated and safety is improved.

Further, since the protector can be mounted immediately before the movement of the cylindrical body, there is no fear of falling off and it is highly reliable, and the cylindrical body does not have a trace of adhesion of foreign matter such as an adhesion mark or a flaw on the product. It does not harm the quality.

Further, according to the present invention, the protector has a simple structure, can be easily manufactured in conformity with the shape of the cylindrical body, and can be repeatedly used, and the cost for transportation and storage can be kept low. It is possible to realize an unmanned management system.
