PURPOSE:To reduce cost with a small-sized, simplified structure by performing transfer loading of a work transfer pallet with only a drive means for moving a table, without requiring other drive means, large-sized hydraulic cylinder and motor. CONSTITUTION:When a table 2 is moved in the direction X1 by actuating a servomotor 10, a chain 66 moves counterclockwise as a pin 93 of a clamp cylinder 92 is fit in a chain hook 66 of the chain 66. At the same time a pinion 95 in engagement with a rack 94 moves on the rack in the direction X1 and a slide body 69 moves in the direction X1. Then, since a chain hook 90 is engaged with a pallet hook 63, a pallet 4 is moved in the direction X1 relative to a table 2 moving in the direction X1 to transfer-load the pallet 4 from a pallet table 30 to a specified position on a table. As a result, no specially large- sized hydraulic cylinder or motor is required, and the structure is simplified with a small size to reduce cost considerably. |
