Abstract: A guide device for bars to be fed to a machine tool includes first holding and guide arrangement and second holding and guide arrangement, arranged to define an advancement zone for the bars that extends according to a longitudinal axis. The first holding and guide arrangement and the second holding and guide arrangement are configured to establish one or more contact zones with the bar, so as to hold in position and guide the bar along the advancement zone. The first holding and guide arrangement and the second holding and guide arrangement extend parallel to the axis and are positioned on sides mutually opposite the longitudinal axis. The first holding and guide arrangement and the second holding and guide arrangement are relatively movable between a rest position, in which the first and the second holding and guide arrangement are at a greater mutual distance and at furthest positions from the advancement zone to allow the positioning of said bar to be guided along the advancement zone, and an engagement position, in which the first and the second holding and guide arrangement are at a lesser mutual distance and nearer the advancement zone so as to come into contact with the bar, adapting to different diameter values of the bar.

Abstract: A device and method for recovering and unloading bar crop ends is suitable for use with a loading apparatus for supplying bars to a machine tool. The devices includes a grasping element suitable for engaging a bar-pushing unit of the loading apparatus and a bar crop-end to be taken and unloaded. A slide element receives and conveys the bar crop ends to a collecting zone. A supporting and transferring unit transfers the grasping element from an upper position, in which it is axially aligned on the advancement trajectory of the bar-pushing unit, to a lower position in which it is near the slide element. The device further includes an ejecting unit that is drivable for penetrating the grasping element in the lower position to eject the crop end and sending the crop end, by the slide element, to the collecting zone.A method is also disclosed for recovering and unloading bar crop ends from a machine tool.

Abstract: A self-centring device for supporting and guiding bars to be fed to a machine tool, including:
a guide body having a through opening, supported rotatably and rotating in a controlled manner around an axis perpendicular to an advancement direction of the bars to be guided, so as to vary the angular orientation thereof around the axis; the guide body is configured to receive and maintain in position the rotating and advancing bars,
a return member configured to oppose a suitable preselectable resistance to the rotation of the guide body around the axis so as to maintain a firm coupling and contact of the guide body with the advancing bar,
a manual selector member configured to adjust a position and control the angular movement of the guide body. The manual selector member includes a screw arrangement cooperating with an oscillation limiting element to set an angular rest position of the guide body in function of the geometry of the bar to be received and guided to said machine tool.-

Abstract: An apparatus for feeding bars to a machine tool includes a rotary drum provided with a plurality of guide units distributed circumferentially and extending parallel to a longitudinal axis, each guide unit having two parts that are reciprocally movable and openable, by a respective lever to receive a respective bar to be advanced to the machine tool. An actuator element is provided and configured to act directly on a specific lever to open the corresponding guide unit. A support assembly is provided for receiving and supporting a plurality of bars in a position adjacent to the drum. A loading unit includes a lifting device that is movable from a lower position to an upper position to pick up one or more bars from the support assembly and lift the bars to the upper position. The loading unit further includes a selector unit for selecting a single bar at a time when the lifting device is in the upper position to transfer the bar to a respective guide unit.
