Device for feeding blanks on a packing machine

摘要

A method and device (1) for feeding blanks (2) on a packing machine (3), whereby a conveyor (6) feeds along a horizontal path (5) a succession (28) of blanks (2) positioned perpendicular to the path (5); the path (5) terminating at a pickup station (S2) having a stop surface (44) defined by a frame (45), which has a withdrawal opening (46) closed partly by fixed teeth (47) and is moved in a direction (49) substantially parallel to the path (5) by the thrust (F) exerted by the blanks (2) and in opposition to a sensor (50) for regulating a traveling speed (V1) of the conveyor (6) to keep the thrust (F) exerted by the blanks (2) on the frame (45) constant. <IMAGE>
