<p>A loader-unloader apparatus (25) (Figure 1) for supplying workpieces (W) to a rotatable chuck (21) of a machine tool (2) from a loading conveyor (22) fed with workpieces and removing machined workpieces from the chuck to an unloading conveyor (23). A track (26) extending along an axis parallel to the longitudinal axis of the chuck (21) carries a trolley (27) movable back and forth along track (26). Pivoted on the trolley (27) is a loading head assembly (32) and an unloading head assembly (33). Each assembly (32,33) includes a head (34,35) having a pair of movable limbs to which are pivotally connected fingers blocks for retaining a workpiece (W). Each head (34,35) is reciprocable toward and sway from the chuck axis and each head (34,35) is pivotable between a position wherein the workpiece has its axis extending parallel to the axis of the chuck (21) andaa position in which the workpiece axis subtends an acute angle to the chuck axis.</p> |
