PURPOSE:To mount a pallet directly against machining unit by moving a movable body to engage/disengage an engaging tool against the engaging portion of pallet then advancing/retracting the movable body and feeding/delivering the pallet against a support/guide device. CONSTITUTION:Engaging tools 33, 34 of a movable body 20 are engaged with engaging portions 35, 36 on the sideface of pallet 8 through individual drive of cylinder units 24, 25 to transfer the pallet 8 directly against the machining unit through back/fro motion of the movable body 20. Consequently, the underface of pallet 8 can be used freely to limit the upward motion of pallet 8 through engagement of the supporting roller 13 and the projection 8a thus to prevent dropout of pallet 8 from the support/guide devices 9, 10 due to the vibration of truck 1. While since an liftable rod 16 insertable into the hole section 8b of the pallet 8 is provided, the pallet 8 can be positioned accurately on said devices 9, 10 and said position can be maintained. |
