〔Effect of the invention〕

According to this invention, the elevating frame 4 is guided by the elevating guide rail 2 fixed to the vertical frame 1 and is moved up and down by the elevating drive device 3.
A rotating frame 7 is attached to the rotating frame 7, which is rotated about a vertical axis 6 by a rotating drive device 5, and a horizontal axis 9 is attached to the rotating frame 7 by a rotating drive device 8.
A rotating frame 10 that rotates around is attached, and a groove-shaped clamp body 12 having a roll shaft fitting groove 11 at both ends of the rotating frame 10 and an opening of the roll shaft fitting groove 11 that opens and closes. A pair of roll shaft clamps 1 consisting of a groove opening/closing member 13
4 are fixed at intervals in a direction perpendicular to the extending direction of the horizontal shaft 9, so that when the rotating frame 10 is placed in a horizontal position, the rotating frame 10
Fitting the roll shaft 49 of the shafted roll 39 into the roll shaft fitting grooves 11 on both sides in the longitudinal direction,
Next, by moving the lifting frame 4 up and down by the lifting drive device 3, the shafted roll 39 can be moved up and down in a horizontal state, and the opening of the roll shaft insertion groove 11 is closed by the groove opening/closing member 13. By rotating the rotation frame 10 by the rotation drive device 8, the roll shaft 49 is held so as not to come off the groove-shaped clamp body 12, and the orientation of the shafted roll 39 can be arbitrarily changed vertically or horizontally. Furthermore, since the roll shaft 49 is held by the groove-shaped clamp body 12 and the groove opening/closing member 13 without gripping the roll, it is possible to prevent the surface of the roll from being scratched. By rotating the rotating frame 7 in the left-right direction, the shafted roll 39 can also be rotated and transferred in the left-right direction. Therefore, one roll transfer device can change the direction of the shafted roll 39 and move it up and down. This provides the advantage of being able to perform various types of transfer, such as transfer and rotational transfer.
