The strip storage device disclosed in Japanese Patent Publication No. 52-20184 is equipped with a rotating drum at the center, and has a plurality of main rollers extending in the radial direction around the rotating drum. An auxiliary roller is placed near the drum (on the side opposite to the drum) to form a circular fixed table. This circular table has a gentle conical shape where the drum side of the main roller is higher than the outside, and a wall is provided around the outer periphery. In this conventional device, a strip is supplied to the rotating drum, a single large-diameter coil is formed on the inner circumference side of the outer peripheral wall, and the large-diameter coil is stored on an outer auxiliary roller. The strip is discharged from the side to the outside.
Therefore, if the strip feeding speed is V ₁ and the strip discharging speed is V ₂ , then when V ₁ > V ₂ , the moving strip expands into a spiral and forms a single large diameter coil on the outer auxiliary roller. stored as V ₁ < V ₂
When , the moving strip contracts into a small diameter spiral around the outer circumference of the rotating drum. Further, when V ₁ =V ₂ , the strip does not expand or contract, but only moves.

Furthermore, the strip storage device disclosed in Japanese Patent Publication No. 15175/1975 is equipped with an annular impacting body disposed in the center and a rotary table that rotates around the annular impacting body, and supplies strips to the outer periphery of the rotating table. By rotating the rotary table, the strip is stored as a large-diameter coil on the rotary table, and the strip is discharged from the annular collision body. Therefore, in the relationship between the strip supply speed V ₁ and the strip discharge speed V ₂ , when V ₁ >V ₂ , the moving strip is stored as a coil on the rotary table due to the rotation of the rotary table, and V ₁ <V 2 . When V ₂ the coil contracts around the annular impactor to form a small diameter coil, and when V ₁ =V ₂ the coil does not expand or contract and the strip only moves.

Next, the operation of the present invention will be explained mainly with reference to FIGS. 3A to 3F.

When introducing the strip S for the first time, the coil turns transfer device 13 is rotated and stopped at the position shown in FIG. S is sent to the tip guide 17, and the tip guide 17
The strip S is guided and sent to the coil turns transfer device 13, and the lower edge of the strip S is guided by the horizontal free guide roller 16, and the tip of the strip is placed between the left and right vertical free guide rollers 15 and the vertical feed roller 18. When the strip tip has been introduced to position _P1 in Figure 3 A, both sides of the strip S are clamped by the vertical feed roller 18 to stop the strip tip, and the tip guide 17 is contracted to return to the original position.

Therefore, the supply of the strip S continues, the tip of the strip S is sent along the inner circumference of the vertical free roller 8 of the small diameter coil device 2, and the strip S is sent to the main equipment on the output side by the strip discharge device 21. At this time, the number of turns of the large-diameter coil _C1 remains unchanged, and the lower edge of the strip S is guided by the horizontal free roller 9 and the horizontal drive roller 11 in the small-diameter coil device 2. .

The automatic threading of the strip S is completed by the above-described processes shown in FIGS. 3A to 3C. Therefore, if the strip supply speed V ₁ and the strip discharge speed V ₂ are synchronized in this state and the threading operation is continued, the strip S can be continuously supplied to the main equipment on the output side.

When stopping the supply of the strip S by the strip supply device 20 (V ₁ =0) and discharging the strip S of the large diameter coil C ₁ to the output side at a speed V ₂ , the drive of the strip supply device 20 is stopped. , rotate the coil turns transfer device 13 in the direction of the arrow (d) in FIG. 3 (clockwise).

Make it. That is, when all the turns of the large diameter coil C ₁ are transferred to the small diameter coil C ₂ , the maximum strip length is L, the total number of coil turns is N,
When the outer diameter of the large diameter coil _C1 is D, the outer diameter of the small diameter coil _C2 is d, and the discharge time is T, the operation is performed so that L=πN(D−d) and T=L/ _V2 . Therefore, the lower edge of the strip will not slide against the horizontal roller and no damage will occur to the edge.

When all the windings of the large diameter coil C ₁ have been transferred to the small diameter coil C ₂ as shown in FIG. Difference ΔV between strip feed speed V ₁ and strip discharge speed V ₂
The coil turns transfer device 13 is reversely rotated in the direction of the arrow (counterclockwise) as shown in FIG. 3 at a speed of =V _{1 -V} 2 (V ₁ >V ₂ ). By counterclockwise rotation of the coil turns transfer device 13, the turns of the small diameter coil _C2 are transferred to the large diameter coil _C1 . When all the windings of the small diameter coil _C2 are transferred to the large diameter coil _C1 , the state shown in FIG. small diameter coil
When transferring the winding of C ₂ to the large diameter coil C ₁ ,
The total number of turns of the small diameter coil C ₂ and the number of turns of the large diameter coil C ₁ is maintained constant.

Once all the windings of the small diameter coil _C2 have been transferred to the large diameter coil _C1 , the operations from c to f in Figure 3 are repeated again. After repeating the operations shown in FIG. 3 C to C a required number of times, the tail end of the strip is finally pulled out of the strip discharge device 21, thereby completing the series of operations. Further, as a method of operation, the number of coil turns smaller than the total number of coil turns N may be transferred between the large-diameter coil device and the small-diameter coil device.

In the embodiments of the present invention, the case of forming a strip coil has been described, but the present invention is applicable not only to strips but also to various belt-shaped objects, and various other changes may be made without departing from the gist of the present invention. Of course.

[Effects of the Invention] According to the strip storage device of the present invention, () By providing the coil turns transfer device, the advancement of the strip can be regulated in the rotation direction of the horizontal roller, so that the strip is not horizontal as in the conventional device. Eliminates damage, wear, noise, etc. at the edge of the strip caused by sliding in the lateral direction on the roller. () Equipped with a coil turns transfer device, it is no longer necessary to thread the tip of the strip manually. Initial winding of plates and coils was performed, but this can be done automatically (automatic threading). () Compared to the conventional method of forming double coils of the same diameter, Since the coil has a small diameter, it can produce various excellent effects such as making the device simpler and smaller.
