WORKPIECE CONVEYING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/034558
Kind Code:
A1
Abstract:
A substrate (2) is provided with a first cam groove (5) and a second cam groove (6) for guiding the conveying of first and second workpiece support parts (3, 4). The first cam groove (5) is configured from a front first cam groove (5a) and a rear first cam groove (5b), and the second cam groove (6) is configured from a front second cam groove (6a) and a rear second cam groove (6b). A pinion (14) is provided in the middle between the first cam groove (5) and the second cam groove (6). The first workpiece support part (3) is slid back and forth by a hydraulic cylinder (32), whereby racks (11a, 11b) of the first and second workpiece support parts (3, 4) travel in opposite directions between an exchanging position and a machining position via the pinion (14). The rear first and second cam grooves (5b, 6b) have curved parts that curve outward, and therefore do not interfere with each other when receiving parts (9A, 9B) pass each other.
