摘要:
Feeder device (10) and method for feeding bars to a machine, for picking up and removing from a bundle at least one bar (11), to prepare it for use in a working machine comprising a drawing assembly (27) . The device (10) comprises a first magnetic assembly (13) for separating from the bundle at least an end segment of a plurality of bars (11) and to dispose at least the end segments of the plurality of bars (11) on a plane distanced with respect to the bundle, and a second magnetic assembly (21) for picking up from the first magnetic assembly (13) one bar (11) at a time from the plurality of bars (11) and to unload the bar (11) in a desired release position. The device (10) comprises an accumulation assembly (60) for receiving in sequence from the second magnetic assembly (21) a desired number of bars (11) so as to form a store, and to transfer the desired number of bars (11) simultaneously to the drawing assembly (27) .
摘要:
Described herein are a method and a device for automatically loading a predetermined number of metal bars (4) from a collection workstation (5), in which the bars (4) are arranged in a bundle (3), to a reception workstation (13). A magnetic-effect lifting device (8) can be displaced between a lowered position for picking up the bars (4) and a raised position. A restricted passage (14) is provided that is to be traversed by the bars (4) that are lifted, such as to enable the lifting device (8) to bring just one bar (4) or portion of bar (4) at a time up to the raised position (13). Each time a bar (4) reaches said raised position, it is pushed laterally by a pusher member (15) and deposited on a support (18). When a predetermined number of bars has been unloaded onto the support (18), a gripper-type transferring device (24) grips said bars and brings them into a final position (7).

The method for automatically feeding the metal profiles (2) in bar form entails gripping a set of the metal profiles (2) from a magazine (5) for collecting said profiles (2) and transferring the set of metal profiles (2) into a raised position. The raised metal profiles (2) are arranged on a movable transfer device (10) provided with means (16) for separating the metal profiles (2), at which a preset number of metal profiles (2) to be fed at each work cycle to the machine arranged downstream is conveyed transversely and counted. The metal profiles (2) are transferred, in the counted number, onto auxiliary supporting means (40) arranged to the side of the transfer device (10) and actuated gradually along the longitudinal axis of the metal profiles (2).

An apparatus for extracting a single bar from a plurality of bars comprises a holding device for nipping the single bar. The holding device comprises nipping members, which face each other and are capable of being opened and closed. The nipping members have a taper space formed therebetween so that only a single bar locating in a peak portion of the taper space of a plurality of bars received therein can be nipped.
