PURPOSE:To improve operation efficiency of a doffing device in a narrow space by providing the doffing device with a package receive plate capable of moving up and down and forward and backward with respet to a machine table of a winder. CONSTITUTION:An arm 44 is fixed to a shaft 41 rotatably fixed to a wrist member 31, a link 45 is fixed to a shaft 46, and a link 49 is rotatably fixed to the shaft 41. The end portions of the links 45, 49 are coupled to each other by a rod 48 to form a non-parallelogram with the arms 44, the links 45, 49 and the rod 48. The shaft 41 is rotated by drive of a servomotor 59, and a piston rod 51a has a pin 58 for connecting the link 49 and the rod 48 to each othr. Accordingly, during running of a truck, the piston rod 51a is extended to fold up a plate 14a on the wrist member 31 side, whereby at the time of doffing a full bobbin P, the servomotor 59 is driven to elevate the plate 14a. Furthermore, the plate 14a can be moved along the limited course by a link forming a non- parallelogram. |
