ABSTRACT:
A gripping device reciprocates vertically towards and away from a table surface having at least one groove to grip and remove articles from the surface. The gripping device has two jaw members connected to a cylinder so that a first jaw member is in a fixed position relative to the cylinder and so that a second jaw member is movable towards and away from the first jaw member. The gripping device and its jaw members and the table surface are configured and positioned so that, in operation, upon movement of the cylinder and jaw members towards the table surface, the first jaw member contacts an article positioned on the table surface having an edge positioned over the groove to move the article into the groove and tilt the article so that a portion of a bottom surface of the article is lifted from the table surface, and the second jaw member then moves towards the first jaw member and the tilted article to contact the bottom surface of the tilted article so that opposing surfaces of the tilted article are gripped between the jaw members for removing the gripped article from the table surface.
