Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a rolled metal foil material into a coil and an apparatus therefor, and more particularly to a method for winding a coil of an aluminum foil material and an apparatus therefor. .

[0002]

2. Description of the Related Art A conventional apparatus for winding a rolled metal foil material such as an aluminum foil material into a coil has a structure shown in FIG. In FIG.
1, 2, 3, 4 are guide rolls, 5 is a metal foil material such as rolled aluminum foil material, 6 is a winding core, 7 is a wound coil, and 8 is for tightly winding the coil 7. Is an ironing roll for pressing the coil 7, 9 is an elevating device such as a cylinder for elevating the roll 8, 10 is an arrow indicating the moving direction of the metal foil material 5, 11 is a rotating direction of the winding core 6. It is the arrow shown.

That is, conventionally, the rolled metal foil material 5 is guided from the guide rolls 1, 2, 3, 4 to the winding core 6 to form a coil 7 of the metal foil material, and the coil 7 is formed. The coil 7 is uniformly and tightly wound by pressing the surface of the coil 7 with an ironing roll 8 during the process. At this time, as the ironing roll 8, there are a case of a rubber roll and a case of an iron roll. When a rubber roll is used, rolling powder (powder) adheres to the roll surface, and after about 1 month, A hardened layer is formed on the surface, and as a result, transfer (adhesion) to the surface of the coil 7 or generation of indentations or the like becomes a factor of product defects. Therefore, in the case of the rubber roll, it was necessary to replace it with a new one in a short period of time.

Therefore, it has been considered advantageous to use an iron roll which is hard to be attached with powder, improves the quality of the winding shape, and is hard and has a long life.

[0005]

However, the rotation of the ironing roll 8 follows the rotation of the coil 7 due to the friction between the surface of the roll 8 and the surface of the coil 7, and the roll 8 is made of iron. With metal rolls such as rolls, stick-slip is repeated to cause vibration,
There was a problem that noise was generated.

The present invention is intended to solve the above problems. That is, the present invention can improve the quality of the winding shape and prolong the life of the roll by using the ironing roll whose surface is made of a hard metal, and the generation of noise due to the vibration of the roll. It is an object of the present invention to provide a coil winding method and an apparatus therefor which are prevented.

[0007]

In order to achieve the above object, a coil winding method of the present invention is to guide a rolled metal foil material from a guide roll to a winding core to form a coil of the metal foil material. In the method for tightly winding the coil by pressing the surface of the coil with an ironing roll during the step of forming the coil, the ironing roll may be one in which at least the surface of the roll is made of metal. In addition, the oil film is formed by supplying oil to the surface of the metal foil material from the guide roll toward the ironing roll.

Further, the coil winding device of the present invention presses the guide roll for guiding the rolled metal foil material to the winding core and the surface of the coil of the metal foil material formed by being wound around the winding core. In a winding device of a metal foil material having an ironing roll, the ironing roll, at least the surface of the roll is made of metal, and oil on the surface of the metal foil material from the guide roll to the ironing roll. It shall be equipped with an oil spray device to supply.

[0009]

According to the coil winding method of the present invention, the rolled metal foil material is guided from the guide roll to the winding core to form a coil of the metal foil material, and the coil is formed during the coil forming step. In the method of tightly winding the coil by pressing the surface of the ironing roll with an ironing roll, the ironing roll has a hard surface because at least the surface of the roll is made of metal. As a result, it is possible to prevent the powder from adhering to the surface, and to achieve a long life and improve the quality of the winding shape. Moreover, since the oil film is formed by supplying oil to the surface of the metal foil material which is directed from the guide roll toward the ironing roll, a cushion layer is formed between the foil materials for coil winding by the oil film, and vibration is generated. It is absorbed and no noise is generated.

Further, according to the coil winding device of the present invention, the guide roll for guiding the rolled metal foil material to the winding core and the surface of the coil of the metal foil material wound by the winding core are formed. In a winding device for a metal foil material having an ironing roll that presses, the ironing roll has at least a surface of the roll made of metal, and on the surface of the metal foil material from the guide roll to the ironing roll. Since the oil spray device for supplying oil is provided, the coil winding method of the present invention can be reliably and easily implemented.

2, the reference numerals 1 to 11 are the same as in the case of FIG. Further, 12 is an oil spray device, and 13 is an elevating device such as a cylinder for elevating the oil spray device 12.

In this embodiment, the rolled metal foil material 5 is an aluminum foil material and the ironing roll 8 is an iron roll. However, the roll 8 may be made of other metal, or the surface of the roll may be plated.

Referring further to FIG. 1, the rolled metal foil 5 of aluminum foil is used as guide rolls 1, 2,
3 and 4 lead to the winding core 6 to form the coil 7, and
During the step of forming the coil 7, the surface of the coil 7 is pressed by the ironing roll 8 of an iron roll to wind the coil 7 tightly. Here, oil is supplied by the oil spray device 12 to the surface of the metal foil material 5 from the guide roll 4 toward the ironing roll 8 to form an oil film. Then, a cushion layer made of an oil film is formed between the winding foil materials of the coil 7, so that the vibration of the ironing roll 8 is absorbed and noise is not generated. Further, as the diameter of the coil 7 increases, the lifting device 13 adjusts the height position of the oil spray device 12 to an optimum position.

[0014]

As described above, according to the coil winding method of the present invention, the rolled metal foil material is guided from the guide roll to the winding core to form a coil of the metal foil material, and In the method for tightly winding the coil by pressing the surface of the coil with an ironing roll during the step of forming the coil, the ironing roll uses at least the surface of the roll made of a metal. Since the surface of the ironing roll is hard, it is difficult for the powder to adhere to the ironing roll, and the life of the ironing roll and the quality of the wound shape can be improved. Moreover, since the oil film is formed by supplying oil to the surface of the metal foil material which is directed from the guide roll toward the ironing roll, a cushion layer is formed between the foil materials for coil winding by the oil film, and vibration is generated. It is absorbed and no noise is generated. Further, the supply of the oil also cleans the ironing roll, and the powder is removed from the surface of the roll. As a result, the vibration source is weakened and noise is eliminated.

According to the coil winding device of the present invention, the guide roll for guiding the rolled metal foil material to the winding core and the surface of the coil of the metal foil material wound by the winding core are formed. In a winding device for a metal foil material having an ironing roll that presses, the ironing roll has at least the surface of the roll made of metal, and on the surface of the metal foil material from the guide roll to the ironing roll. Since the oil spray device for supplying oil is provided, the coil winding method of the present invention can be reliably and easily implemented. In other words, the life of the ironing roll and the quality of the coil winding shape can be improved.
Moreover, it is possible to reduce the vibration of the ironing roll and eliminate noise.
