Filter cigarettes which are produced in a filter tipping machine are transported by a severing conveyor in the form of two rows wherein the filters of cigarettes in one row are adjacent to the filters of cigarettes in the other row. The cigarettes of the one row are thereupon inverted end-for-end by sets of pairwise arranged pivotable levers one of which withdraws a cigarette from the one row during movement along an endless circular path and turns the removed cigarette through 90 degrees about an axis which is normal to the cigarette and is remote from its filter while the one lever travels along an arc of 180 degrees. The thus partially inverted cigarette is taken over by the other lever of the respective pair and is turned through additional 90 degrees while the other lever travels along an arc of 180 degrees. The thus inverted cigarettes of the one row are thereupon shuffled with the non-inverted cigarettes of the other row by moving the two rows of cigarettes axially toward each other on two shuffling drums so that the two rows are converted into a single third row which is ready for testing and transport to storage or packing.

Method of tip turning filter cigarettes or the like

Apparatus for tip turning filter cigarettes or the like

A tray filling apparatus wherein a suction head accumulates rows of cigarettes and a pusher transfers the rows into a tray which is supported by an endless chain conveyor. The suction head and the pusher receive motion from a drive which includes a variable-speed DC-motor, a step-down gearing which is driven by the output shaft of the motor, and a mechanical transmission having a first component which moves the suction head between a lower position in which the latter accumulates a row of cigarettes and one of two raised positions, and a second component which moves the pusher forwardly not later than when the suction head reaches a raised position. The forward movement of the pusher is slower than its return movement to retracted position and the characteristic RPM curve of the motor is determined by a control circuit which includes three signal generators one of which starts the motor, another of which decelerates the motor after the suction head returns to lower position and the pusher reassumes its retracted position, and the third of which arrests the motor while the suction head and the pusher respectively dwell in their lower and retracted positions. A second electric motor drives the conveyor for an empty or partly filled tray through the medium of a second transmission in stepwise fashion upon completion of each forward stroke of the pusher.
