DEVICE FOR TRANSFERRING FILTER SEGMENTS IN THE PROCESS OF MANUFACTURING MULTI-SEGMENT FILTER RODS

摘要

Device for transferring cylindrical segments from a hopper (3) onto a grouping belt provided with a guiding drum (1), having flutes (2) on its periphery and a circumferentially closed conveyor (8) which delivers segments to a rotary element (24) with pushers (25). Conveyor (8) is provided with seats (10) with a catching element (11) for catching segments, and transferring the segments from the conveyor (8) to the element (24) is effected by means of a spiral drum (23). The device has a push-down element (15) constituted by a cam provided with a groove of a height corresponding to the diameter of the segment. The catching element (11) has the form of a depression (21) in the body (12) of the seat (10) shaped as a half of a cylinder, provided with locks (22) on edges, the axis of the depression (21) being perpendicular to the direction of motion of the conveyor (8). The conveyor (8) has projecting spigots for mounting the seats (10), and is constituted by a flexible belt or a chain. The spiral drum (23) can have the form of a cylinder or have at least one conical surface, and underneath the drum (23) there is a ramp having a surface parallel to the surface of the drum (23) having a channel along which the conveyor (8) with seats (10) moves so that the ends of segments protruding out of the catching element (11) meet the surface of the ramp which pushes the segments consecutively into the groove of the spiral of the drum (23).
