PURPOSE:To confirm existence of pallet on turning table easily and reliably without causing erroneous operation by fitting a movable pin from the interior of turning shaft into the recess of pallet then detecting. CONSTITUTION:A movable pin 40 is arranged movably up and down in the turning shaft fixed above an elevating table 23 and detection mechanism 53 is arranged while passing through the interior of said pin 40. The movable pin 40 fitted in a bush 38 mounted in the through-hole 36a of pallet 36 will secure the pallet 36 firmly to the turning table while the roller 62 of detection mechanism 53 contacting with the bush 38 will lower the push rod 54 through respective link member 55, 56. Consequently, it can be detected easily and reliably that the lower end of push rod 54 will press the operating chip 68a of limit switch 68 to mount the pallet 36 on the turning table. |
