Abstract
For removing blanks (10) from a blanks magazine (14, 15) a transfer roller (18, 19) is employed which grips the blank (10) with a suction head (20) and takes it along its circumference. The transfer roller (18, 19) must be moved back and forth along a linear path of movement below the blanks magazine (14, 15) by rotating about its own axis. This movement is driven by a crank gear —crank arm (24) and strut (26) —which are directly, i.e. by means of a swivel arm (28), connected to the transfer roller (18, 19). A differential gear (23) acts to produce a linear movement of the transfer rollers (18, 19).
Claims12
Apparatus for handling blanks (10) in a packaging machine for the manufacture of cigarette packs of the hinge-lid type, with at least one blanks magazine (14, 15), from which blanks (10) can be removed individually by a withdrawal assembly with a transfer roller (18, 19) and fed to a discharge conveyor, in which the transfer roller (18, 19) can move back and forth at an open bottom side of the blanks magazine (14, 15), taking a blank (10) along its circumference in each case, characterized in that the transfer roller (18, 19) is attached to a bearing member which can be moved back and forth by a gear mechanism such that the transfer roller (18, 19) is moved back and forth along a straight-line path of movement, wherein the bearing member is a swivel arm (28) associated with each transfer roller (18, 19), the gear mechanism comprises a movement gear (22) and a differential gear (23), and the swivel arm (28) can be moved back and forth by means of the movement gear (22) and moved along a straightline path of movement with respect to the direction of movement by means of the differential gear (23).
