Abstract:
1. A device for automatically feeding bars, blanks or half-finished workpieces to a machine tool, more particularly a computer numerical controlled (CNC) lathe, and automatically unloading the machined workpieces, comprising a frame supporting a workpiece loading/unloading device that is capable of successively or simultaneously moving at least in a vertical Z axis and a horizontal Y axis in order to introduce a workpiece that is to be machined through a machining space in front of the lathe and to extract the workpiece from this space after machining, a workpiece magazine, a trash bin for residual material or remainders, and an integrated bar feeder device that allows loading bars through the rear into the spindle of the lathe, the magazine allowing to receive at least one bar to be machined, wherein the integrated bar feeder device comprises a carriage to which a bench for receiving the bars is connected, said carriage and said bench being connected to a first motor so as to be vertically displaceable in a W axis, and wherein the bench is connected to a second motor so as to be furthermore horizontally displaceable autonomously in an X axis, and so as to allow automated loading and unloading of any blank or bar and a controlled recovery of any machined workpiece and of any residual material.
