CASSETTE CHANGING APPARATUS FOR INDEX-FEED MACHINING SYSTEMS

摘要

Cassette changing apparatus (16) for index-feed machining systems having such a construction that a plurality of machining units (12), in which cassettes (18) having machining means are provided, are disposed at predetermined intervals in the workpiece feeding direction in accordance with a plurality of machining processes; the cassette changing apparatus (16) comprising a cassette transfer unit (19) adapted to be movable in such a direction as to intersect with the workpiece feeding direction on a plane, and a cassette holder (17) adapted to be approachable to and detachable from an index-feed machining system (11); a cassette (18) being extracted from the index-feed machining system (11) and housed in the cassette holder (17) by means of the cassette transfer unit (19), and then another cassette holder (17) housing a new cassette (18) being moved to a loading position (17a) and mounted on the machining unit (12) by means of the cassette transfer unit (19).
