PURPOSE:To easily and surely perform positioning of a pallet and its conveyance to be synchronized with a transfer bar in its reciprocating motion by forming an adapted part to the pallet and a cam part in the transfer bar and providing a positioning member, stopped to and detached from the pallet in the cam part, in a stop position of the pallet. CONSTITUTION:When a transfer bar 4 is advanced, a fixedly provided adapted part 28 presses a pallet 30 to be moved. And providing in a stop position a positioning member 31, its cam follower 32 is inserted into a cone-shaped cam groove formed in the transfer bar 4. The positioning member 31 is stopped to a pallet groove 30a by a spring 36, and stopping advancing the transfer bar 4, the pallet 30 is positioned. Next the transfer bar 4 is turned, retracting the adapted part 28 to be turned, and the positioning member 31 is detached from the pallet 30. In the next time of advancing, the transfer bar 4 is reversely rotated returning the adapted part 28 to the original position. |
