PURPOSE:To easily improve in function from a two-plane juxtaposition type APC to a multiple plane APC by providing a pallet stocker having plural pallet storing tables and intermittently moving a pallet by disengaging a shifter fork and moving a shifter. CONSTITUTION:There are provided a table 2 which is moved and positioned by numerical control to two pallet exchange positions of a numerical control machine tool and a pallet stocker 60 having plural pallet tables 62 which can be positioned at two pallet exchange positions corresponding to a pallet exchange position. A pallet 17 having hooks at plural portions thereof is intermittently moved by a shifter having a shifter fork. Thus, a function can be raised to multiple plane APC only by adding a simple pallet stocker 60 without remarkably remodelling a two-plane juxtaposition type APC. |
