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).
Claims13
Apparatus for handling blanks (10) in a packaging machine, in particular for the manufacture of cigarette packs of the hinge-lid type, with at least one blanks magazine (14, 15), from which the blanks (10) can be removed individually by a withdrawal assembly with transport roller (18, 19) and fed to a discharge conveyor, it being possible for the transport roller (18, 19) to 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, in particular a swivel arm (28), which can be moved back and forth, especially pivoted, by a gear mechanism such that the transfer roller (18, 19) is moved back and forth along a straight-line path of movement.
