BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding device for a thin metal plate including a foil.

[0002]

2. Description of the Related Art A thin metal plate rolled by a rolling mill or a thin metal plate in a metal working line is wound by a winding device using a belt. An example of this type of winding device is shown in FIG. 6, which is a front and rear device mounted on a machine base 62 on which a winding shaft 61 is pivotally supported so as to be vertically swingable through a horizontal shaft 63. A pair of frames 64, a swing cylinder 65 of the frames 64, tip guide arms 67, 68 swingably attached to the opening side ends of the U-shaped recesses 66 of the frame 64, and the tips of the arms 67, 68. Pivoted tip guide rollers 69,70
, The arm rocking cylinders 71, 72, and the frame recess 66.
A plurality of rollers 73 arranged around the
It is composed of an endless belt 74 wound around 9,70,73, a deflector roller 75 and the like.

The thin metal plate 76 rolled by the rolling mill and sent out is guided between the upper and lower tip guide rollers 69, 70 between the upper and lower guide rollers 69, 70 via the deflector roller 75, and is guided by the belt 74. It is designed to be wound around the winding shaft 61 while being sandwiched.

[0004]

In the prior art described above, when the winding start end 76A of the metal thin plate 76 makes one round and comes out between the upper end guide roller 69 and the winding shaft 61, as shown in FIG.
As shown in Fig. 7, the angle θ between the succeeding thin metal plate 76 and the winding start end 76A is quite large, and the winding start end 76A is
And the succeeding metal thin plate 76 do not smoothly enter into S and are wound in a state in which there is a slack and a gap is formed between the winding shaft 61 and the take-up shaft 61.

Therefore, even if the tension of the belt 74 is increased, the winding force of the metal thin plate 76 is weak, and the metal thin plate 76 cannot be tensioned even after a predetermined number of windings (usually several turns). There is a problem that slip occurs between the winding shaft 61 and the thin metal plate 76. Therefore, in order to apply a predetermined tension to the thin metal plate 76 so as to eliminate the slip, the number of windings must be increased, and the length thereof becomes long, so that the yield is poor and the productivity is reduced. was there.

The present invention has been made in view of the above circumstances, and an object thereof is to smoothly and closely wind a thin metal plate in a tightly wound manner without slackening the winding start end.
It is an object of the present invention to provide a metal thin plate winding device capable of preventing slippage between a metal thin plate and a winding shaft, preventing damage to the metal thin plate, and improving yield and productivity.

[0007]

In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, in a winding device in which a thin metal plate is wound while being sandwiched by an endless belt around a winding shaft, a small-diameter roller is further provided at the tip of a tip guide roller around which the belt is wound. It is characterized in that it is wound around and the small diameter roller is constantly pressed against the winding shaft.

The present invention is also characterized in that the small diameter roller is supported by a backup roller.

[0009]

According to the present invention, the winding start end of the fed thin metal plate is sandwiched between the belt and the winding shaft from between the small diameter roller and the tip guide roller located at the opposite position, and the winding shaft is wound. It is wound on the take-up shaft while being pinched by the belt as it rotates, and the winding start end passes through the tip guide roller and is pressed against the take-up shaft by the small-diameter roller. The angle formed with the thin plate is reduced, and the thin plate is guided without sagging between the winding shaft and the winding shaft, and is wound in close contact with the winding shaft. Therefore, slip does not occur between the metal thin plate and the winding shaft, and a predetermined tension is applied to the metal thin plate.
