[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pay-off device for a strip.

[0002]

2. Description of the Related Art While a strip is being fed from a coil of a wide strip, the strip is cut into multiple strips by a slitter and wound up as a thin strip coil. Then, the strip end of the winding coil of the thin strip and the strip end of the feeding coil are connected by welding, and various operations are performed while winding as a long strip.

[0003] Conventionally, one coil is set on each reel of the pay-off device and is passed through each reel.

[0004]

[Problems to be Solved by the Invention] Therefore, the work efficiency was poor.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a pay-off device for a strip which sets a plurality of coils at a time, and which can be fed out safely and securely.

[0006]

Means for Solving the Problems To solve the above problems, the configuration of the present invention is as follows. That is, a shaft main body projects concentrically and horizontally from one end of an expanding / contracting portion having a horizontal shaft on which a strip coil is set, and a rewinding portion rotatably supported by a bracket and a through-hole for rotating the shaft main body. Plate drive unit and first to prevent coil loosening during operation
Brake means, allowing rotation during feeding of the strip,
A pay-off device for a strip having a second brake means for stopping rotation while the feeding is stopped, wherein a slide table on which all the parts are mounted and an axial direction of a shaft main body of the winding unit are mounted on the slide table. A reciprocating drive unit slidably driven by power in parallel, a guide moving shaft slidably supported by the slide table and extending parallel to the axial direction of the winding shaft main body, and a tip of the guide moving shaft , A guide arm extending in the radial direction and attached to the end, an advancing / retracting means connected to a distal end of the guide moving shaft, and a means for rotating the guide moving shaft.

[0007]

After setting a plurality of coils in the expanding / contracting portion of the rewinding shaft, the coil edge guide prevents the strip plate from becoming uneven. That is, the rotation means is driven, the guide arm is rotated, and the posture of the guide arm is opposed to the side surface of the band coil. Next, the advancing / retreating means is operated, and the guide moving shaft is retracted, and stops in a state where the guide arm is in contact with the strip coil. As a result, the strip is prevented from becoming uneven.

Next, the reciprocating motor is driven, the center of the first coil at the end is aligned with the line center, and the first sheet is passed by the passing motor. When the operation is completed and normal operation is started, the shaft of the threading motor is released and becomes free.
Also, at this time, the first brake is applied, and back tension is applied to the passed strip. Next, a winding operation is performed. Similarly, for the second coil, the reciprocating motor is driven, the slide table moves, and the coil center is adjusted to the line center. Then, the guide arm corresponds to the end face of the coil of the second row, and unevenness is prevented. Hereinafter, the same operation is performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to an embodiment shown in the drawings.

In FIGS. 1, 2 and 3, the rewinding portion 1 has a rewinding shaft 1a in which a shaft body 1b projects horizontally and concentrically from one end of an expanding / contracting portion 1c having a horizontal axis on which a strip coil is set.
It is rotatably supported by a bracket 1d, and an expansion / contraction hydraulic cylinder 1e is connected to its end.

In the plate driving unit 2 for rotating the shaft main body 1b, a sub shaft 2a is rotatably provided parallel to the rewind shaft 1a and spaced apart in the horizontal direction. 2b is provided to transmit the rotation. Then, an AC cyclo motor serving as a threading motor 2d is connected to one end of the sub shaft 2a via an air clutch 2c. A powder brake serving as a first brake 2e is connected to the other end of the sub shaft 2a.

A second brake means 3 for permitting rotation of the band plate during feeding and stopping rotation while stopping feeding is provided with a disk 3a fixed to the rewinding shaft 1a and a disk mounted on the slide table 4 described below. It consists of a brake 3b.

The slide table 4 on which all the parts are mounted is:
The reciprocating drive unit 5 is slidable by power in parallel to the axial direction of the rewind shaft 1a. That is, the linear motion guide 5b is provided on the lower surface of the slide table 4, and is slidable on the rail 5a. The tip of the piston rod of the hydraulic cylinder as the reciprocating motor 5c is fixed to the slide table side, and the cylinder side is installed on the base B side via a pin support.

4, 5, and 6, a guide moving shaft 12 serving as a spline shaft is slidably supported on the lower surface of the slide table 4 via a support member 11, and the rewind shaft 1
It extends parallel to the axial direction of a. A guide arm 15 is attached to the tip of the guide moving shaft 12 and extends in the radial direction. Two guide rods 1 parallel to each other across the guide moving shaft 12
Reference numeral 3 slidably penetrates the support member 11, and both ends of these three shafts are integrated by a connecting member 14. A hydraulic piston cylinder as an advancing / retreating means 16 is connected near the tip of the guide moving shaft 12. A hydraulic piston cylinder serving as a rotating means 19 is connected via a lever 18 to a spline cylinder 17 fitted to the guide moving shaft 12 so as to rotate the guide moving shaft 12.

The operation state will be described above. A plurality of coils A (A ₁ , A ₂ , A ₃ ...) Are provided at the expansion / contraction portion 1 c of the rewind shaft.
Is set, the coil edge guide portion 10 prevents the strip plate from scattering. That is, the rotation means 19 is driven, and the guide arm 15 is rotated via the lever 18, so that the guide arm 15 faces the side surface of the strip coil. Next, the advancing / retreating means 16 is operated, and the guide moving shaft 12 is retracted while being guided by the guide rod 13, and the guide arm 15 is moved to the strip plate coil A.
Stop in contact with. As a result, the strip is prevented from becoming uneven.

Next, the reciprocating motor 5c is driven, and the center of the _first coil A1 at the tip is aligned with the line center.
The first sheet passing is performed by the sheet passing motor 2d. When the operation is completed and normal operation is started, the air clutch 2c is released, the shaft of the threading motor 2d is released, and the motor becomes free. Also,
At this time, the electric current of the powder brake 2e is applied, and a back tension is applied to the passed strip. Next, a winding operation is performed. Similarly, for the _second coil A2, the reciprocating motor 5c is driven to move the slide 4 so that the coil center is aligned with the line center. Then, the guide arm 15 corresponds to the end face of the coil A2 in the _second row, thereby preventing unevenness. Hereinafter, the same operation is repeated in order.
