Equipment for loading bars to be machined on a device for presenting and feeding said bars to a machine tool

摘要

A bar lifting equipment in automatic bar loading devices for a machine tool comprises a plurality of arms (14) driven to rotate in a vertical plane parallel to said bars (15) for displacing their end, which end is provided with means for grasping said bars (15), from a first lower position in which one bar (15) is drawn out a supply source to a second upper position where a rotating comb device (29) is provided. Said comb device (29) being suitable for drawing out said bar and dropping it by gravity onto a channel-shaped jaw (16), said jaw (16) being suitable for introducing said bar (15) into the machine tool.
