PURPOSE:To provide a driver device with chain drive to move pallets continuously with derectional loop arrangement with small pallet spacing by incorporating such a construction that each pallet can be revolved round a rotary shaft with chain engagement held as it is. CONSTITUTION:In a revolving device for pallet magazine to be used in a machining center system, square pallet magazines 2 each containing six pallets 1 are arranged in two rows. Coupling of drive chain 6 with pallets 1 is made by putting the pallet detent part 9 provided at the chain 6 in engagement with a circumferential groove fixed solidly to a rotary shaft borne in a central hole of each pallet base 11, on which a pallet holding revolving plate 10 is placed. According to this construction, pallets can be driven continuously by means of chain drive in directional loop arrangement with small pallet spacing. |
