Device and method for recovering and unloading bar crop ends from a machine tool

A device for recovering and unloading crop-ends of bars, which is suitable for being applied to a loading apparatus for supplying said bars to a machine tool, comprising:

• a grasping element suitable for engaging, at a first end, a bar-pushing unit of said loading apparatus, and, at a second end, a crop-end to be taken and unloaded, said grasping element comprising a tubular bush body in which there are obtained a first seat for receiving and engaging said bar-pushing unit and a second seat for receiving and engaging said crop-end,
• a slide element for receiving and conveying said crop-end to a collecting zone;
• a supporting and transferring unit for said grasping element, said supporting and transferring unit being movable from an upper position, in which said grasping element is axially aligned on the advancement trajectory of said bar-pushing unit, to a lower position in which said grasping element is placed near said slide element, and
• an ejecting unit that is drivable for penetrating said grasping element placed in said lower position to eject from said grasping element said crop-end and send the crop-end to said slide element,
• in said tubular bush body there being longitudinally obtained a through passage opening that connects said first seat to said second seat, said through passage opening being shaped to enable said ejecting unit to penetrate, through said first seat, said second seat to eject said crop-end,
• said first seat and second seat being made of a adhesion promoting material arranged for ensuring firm grasping of said crop-end and stable coupling between said grasping element and said bar-pushing unit.
