1. Device for transferring a workpiece pallet between a pallet rail station and the workpiece table of a machine tool, consisting of a rectangular pallet carrier (10) located between the pallet rail station and the workpiece table and rotatable by motor operation about its vertical axis (20) and comprising longitudinal guides (11) together with motor-operated slides (18) for the conveyance of a pallet in a longitudinal direction by means of the pallet carrier, characterised in that the rectangular pallet carrier (10) is rotatable through 90 degrees at a time between an idle position, in which it is uncoupled from the workpiece table (2) and from the transfer point (8) of the pallet rail station (6), and a transfer position, in which its longitudinal guides (11) bridge the gap between the workpiece table (2) and the transfer point (8) that in the pallet carrier a motor-driven endless chain (14) is mounted whose upper side runs parallel with the longitudinal guides (11) on the pallet carrier (10), and that the slides (18) are mounted at intervals on the chain belt (14) such that one of the slides (18) engages in an initial movement cycle with a front cam stop (19) on the pallet (12) in order to transfer the latter from the transfer point (8) or the workpiece table (2) onto the pallet carrier, and that the next following slide (18) engages with a further cam stop (19) on the pallet and moves the latter from the pallet carrier (10) onto the workpiece table (2) or the transfer point (8). |
