Claims11
A pallet changing apparatus comprising:
- a pallet setup base,
- a table,
- at least one pallet changing arm configured for transferring a pallet between the pallet setup base and the table,
- a turning shaft for supporting the at least one pallet changing arm in a manner such that the at least one pallet changing arm moves freely in a vertical direction,
- wherein the table is configured to move back from and forth to a side of the turning shaft,
- the table including:
- an upright portion extending upwardly from and at a leading end of the table on a side of the table that is closest to the turning shaft, and
- an oscillating portion which is supported by the upright portion so as to oscillate freely about an oscillating center axis so as to position a workpiece via a pallet mountable to the oscillating portion,
- the pallet changing apparatus further comprising a covering portion firmly fixed to the turning shaft at an upper side of the covering portion, and which covering portion covers a turning supporting portion positioned at a lower end of the turning shaft, and the covering portion including an insertion and removal hollow space which allows the upright portion to be inserted and removed freely therethrough, and
- wherein the at least one pallet changing arm includes a pallet supporting portion extending in a horizontal direction, the pallet supporting portion configured for transferring a pallet from a position on one side of the pallet changing apparatus, at which side of the pallet changing apparatus the insertion and removal hollow space is located, to a position on an opposite side of the pallet changing apparatus.
