PURPOSE:To lighten the damage of rotating gear of driving side and also, to easily make the above mentioned mechanism detachable and moreover, to make small size, by hanging the rope provided at a suitable place of up and down moving member and composing so as to pull out the coupling from rotating shaft of the side to be moved by up and down movement of up and down moving member. CONSTITUTION:Moving quantity of each member 8, 9, 10 of the side to be moved, is doubled against that of the piston rod 14 by the pulley 18 and the rope 19. Accordingly, the moving quantity of each member of driving side is able to set up small and damage of the gear 2 by the accompanied gear 3 by decreasing up and down moving quantity of the gear 2 on the rotating shaft of driving side. Also, meximum stroke for pulling out the coupling 8 from the roll end, is necessary to be larger than the dimension l1. As against it, detachment of the coupling 8 against the roll is able to carry out in a short time by decreasing the stroke of the cylinder 12, because the corresponding quantity of displacement l2 of the shaft body 10 of the side to be moved and the shaft body 7 of driving side, is decreased. |
