DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a strip winding and unwinding machine that is installed in a rolling line or the like and winds and unwinds a strip.

[Conventional technology] A conventional take-up and unwind machine is shown in FIG.

Opposing reel support shaft devices 2.2 are provided on both sides of the pit 1.

Each reel support shaft device 2.2 has its reel support shaft 3.
The reel support shaft 3 is connected to an opening/closing cylinder 4, and is configured to move by expanding and contracting the cylinder. A truncated cone-shaped cone head 6 that can fit into the shaft end of the reel shaft 5 is fixed to the tip of the reel support shaft 3. When the reel support shaft 3 is projected by the cylinder 4, both cone heads 6.6 are fitted to both ends of the reel 4IIll neck 5, and the reel shaft 5 is held between both reel support shaft devices 2.2.

Also, on the other hand, the reel support shaft 3 of the reel support shaft device ffi 2
is connected to a drive motor (not shown), and the reel support shaft 3 is rotated by the motor to wind up the strip or the like.

When removing the coil after winding, first suspend the reel using a crane, etc., then shorten the cylinder 4 and remove the cone head 6.
By moving the reel @5 away from the reel shaft 5, the reel @5 can be removed from the take-up and rewind machine. To attach the reel, just reverse the above steps. In the figure, 31 indicates a coil.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional winding and unwinding machine, it is difficult to perform coil hand linking (coil conveyance, reel shaft exchange, coil tip removal, etc.) of the welded coil after the previous coil rolling. This takes time, and as a result, downtime during rolling becomes significant, which hinders productivity.

In view of these circumstances, the present invention seeks to significantly shorten the downtime of a rolling mill during coil handling.

In the present invention, a pair of frames facing each other are rotatably provided with horizontal revolution axes so that they can be rotated by a required drive device, a revolution frame is attached to opposite ends of the revolution shaft, and upper and lower ends of the revolution frame are provided. A reel support shaft with a cone head attached to the opposing end is provided rotatably and movably in the axial direction, and is moved in the axial direction by an opening/closing cylinder. ° A positioning pin was provided to fix the revolving frame at each rotated position, and a clutch unit was provided on either side of the frame, making it possible to connect and disconnect the reel support shaft and the reel drive motor via the clutch unit. It is characterized by this.

[Function] Rotate the revolving frame via the revolving axis to position one coil or reel shaft on the winding and unwinding work side, and replace the other coil or reel shaft by the required means. . The exchange of the coil and reel shaft is performed by moving the cone head close to and away from the reel support shaft using an opening/closing cylinder, and the reel support shaft is rotated by the reel drive motor through the clutch unit.
