Abstract
A feed and stacking device for slab-shaped workpieces has a rigid frame which is pivotally mounted on a base stand for movement between a horizontal position and a raised position. A support bar is movable along the length of the frame and carries a plurality of vacuum operated pick-up devices for transferring a workpiece from a stack to a processing device or vice versa.
Claims10
A feeding or stacking device for slab-shaped workpieces comprising:
- a base stand,
- a rigid frame pivotally mounted on said base stand for pivotal movement about a pivot axis between a horizontal position and a raised position,
- a support bar movably mounted on said frame for movement along said frame toward and away from said pivot axis,
- first actuator means mounted on said frame for moving said support bar,
- workpiece handling means movably mounted on said support bar for movement perpendicular to said support bar,
- second actuator means carried by said support bar for moving said handling means,
- third actuator means mounted on said base stand for pivoting said frame about said pivot axis and
- alignment means mounted on said frame for aligning a workpiece disposed in a horizontal plane.
