Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a strip storage device in a continuous strip processing facility.

[0002]

2. Description of the Related Art A conventional thin wide strip storage device is mainly of a type in which a moving roll row 11 moves vertically or horizontally as shown in FIGS.

Further, as shown in FIGS.
No. 2,240,107 discloses a plurality of guide rollers 1.
A coil device 15, 1 for storing the strip 1 wound in a coil shape on the outer periphery of a roller cylindrical body 14 provided with 3 in a cylindrical shape.
A strip storage device having two sets of 6 is disclosed.

[0004]

In the apparatus shown in FIGS. 3 and 4, the number of strip passes increases as the strip storage amount increases, which causes not only the main equipment but also the civil construction cost. Further, in the apparatus shown in FIGS. 5 and 6, since the strip 1 is wound in a coil shape on the outer circumference of the roller cylindrical body 14 having the plurality of guide rollers 13 in a cylindrical shape, several strips overlap each other. Then, when the strips are wound or rewound, there is a big problem in quality that slips occur due to a speed difference between the overlapping strips and slip occurs.

[0005]

SUMMARY OF THE INVENTION The gist of the present invention comprises a strip redirecting roll and a plurality of strip support rolls for helically winding a strip around the redirecting roll, the support roll comprising: A plurality of rows are arranged in a radial pattern, and the roll rows are alternately a fixed roll row and a moving roll row.The supporting rolls of the fixed roll row are arranged outside the spirally wound strip, and the supporting rolls of the moving roll row are arranged inside. However, the strip storage device is provided with a roll row moving device for moving the moving roll row in the radial direction.

[0006]

Since this apparatus has the strip direction changing roll and the plurality of strip supporting rolls for spirally winding the strip around the direction changing roll, the strips are not overlapped with each other. Can be stored. The strip is inserted from the strip-direction changing roll and spirally wound and wound on the support roll from the inner side to the outer side, or conversely, wound from the outer side to the inner side sequentially and discharged from the strip-direction changing roll.

A plurality of support roll groups are radially arranged, and the roll trains are alternately a fixed roll train and a moving roll train. The supporting rolls of the fixed roll train are arranged on the outside of the spirally wound strip. Since the row support rolls are arranged on the inside and a roll row moving device is provided for moving the moving roll rows in the radial direction, the moving roll rows are moved to the outside when the strip storage amount is increased. On the contrary, when the strip storage amount is reduced, the moving roll row is moved inward.

The present invention ensures about twice as much strip storage as compared to moving the entire roll row and expanding and contracting the strip. The reason is that, as shown in FIG. 1, the two sides of a substantially equilateral triangle are different from the one side, and the two sides 2a are moved in the radial direction with every other row of rolls, and one side b is the entire row of rolls. This is because the case is moved to expand or contract the strip.

As described above, the occupied space of the strip storage device of the present invention is about 1/2. Then, in order to realize the compactness of the strip storage device, it is possible to store the strip as long as possible in a limited space area by utilizing the circular space.

[0010]

Embodiments of the present invention will be described below with reference to FIGS.

A strip direction conversion roll 5 is arranged in the central portion of the strip storage device, and a plurality of strip support rolls 2 are spirally arranged around the strip direction conversion roll 5. At the same time, the support rolls 2 are also arranged radially with respect to the center of the spiral circle. Every other radial roll row is a fixed roll row 4 and a moving roll row 3 that can move in the radial direction. The supporting rolls of the fixed roll row 4 are arranged outside the spirally wound strip 1, and the supporting rolls of the moving roll row 3 are arranged inside the strip 1.

The strip 1 that has entered from the central portion of the spiral circle passes through the strip direction changing roll 5 and is wound around the support roll of the nearest movable roll train 3 on the innermost side of the spiral circle, and sequentially supports the movable roll train 3. It winds around the roll, gradually progresses in a spiral shape to the outside of the circle, and goes out of the strip storage device from the support roll of the fixed roll row 4 at the outermost periphery through the pinch roll 8.

Thus, the initial spiral winding of the strip is carried out by the supporting rolls of the moving roll train 3, whereas the supporting rolls of the fixed roll train 4 only hold the outside of the spirally wound strip.

When the strip is stored in the strip storage device, the moving roll row 3 is provided with a roll row moving device 6 provided on the outer peripheral portion of the storage device, for example, an electric winch, to apply a predetermined tension to the strip and outside the circle. Move radially towards. On the other hand, when paying out the strip, the roll row moving device 6 is rewound, and the moving roll row 3 moves toward the inside of the spiral circle by the tension of the strip.

Incidentally, the strip entering direction is opposite to the above,
That is, the strip direction changing roll 5 may be used as the outlet of the strip.

FIG. 2 is a sectional view taken along the line AA in FIG. 1, in which the moving roll row 3 supports a plurality of supporting rolls 2 by a moving roll row supporting frame 10, and the supporting frame 10 is a row of rolls via a wire rope 7. The moving device 6 has a structure in which the moving roll row 3 can be moved by pulling.

INDUSTRIAL APPLICABILITY The present invention makes it possible to realize small-sized and large-capacity strip storage, and is particularly suitable for thin, wide and high-speed lines. Due to the compact size, not to mention the equipment cost,
It is very effective in reducing equipment costs including civil engineering and construction costs. Moreover, in addition to being compact, the wrap between the strips can be completely eliminated, and problems such as slip scratches between the strips can be eliminated.
