Filter rod sections are transported sideways from a magazine containing a pile of parallel sections toward positions of alignment with the inlet of a pneumatic conveyor and are propelled into the conveyor at a transfer station where they continue to move sideways. In order to avoid damage to sections during propulsion into the conveyor, the duration of complete transfer of successive sections into the inlet is monitored in order to generate signals denoting the intervals of axial advancement of successive sections all the way into the conveyor. Such signals are compared with signals denoting those intervals of sidewise movement of sections past the transfer station during which the sections can move axially without being damaged by the stationary inlet of the conveyor. The evaluating circuit which compares the signals generates defect signals when the transfer of sections in unsatisfactory, and such defect signals are used to reestablish the possibility to advance undamaged sections into the conveyor or to expel the fragments of destroyed or partially destroyed sections from the conveyor and/or from those parts of the apparatus which supply articles to the transfer station.

Method and apparatus for transporting filter rod sections

Apparatus for transferring rod-shaped articles from the outlet of a magazine for parallel articles into the inlet of a pneumatic conveyor wherein the articles are moved in the direction of their longitudinal axes comprises a rotary drum-shaped conveyor having a peripheral surface provided with axially parallel flutes. When the rotary conveyor is driven, its flutes advance seriatim past the outlet of the magazine to accept discrete articles which are thereupon moved sideways toward alignment with the inlet of the pneumatic conveyor. A pneumatic ejector system is utilized to propel successive articles from their flutes into the pneumatic conveyor. The apparatus employs a hood having a concave surface which is complementary to a portion of the peripheral surface of the rotary conveyor. A median portion of the concave surface is maintained close to but still out of contact with the adjacent portion of the peripheral surface by two stationary sealing members which are adjacent to but still out of contact with the end faces of the rotary conveyor. The hood is movable between a first position in which its concave surface abuts the sealing members but is out of contact with the peripheral surface of the rotary conveyor and a second position in which the hood affords access to the article propelling station.

A sender propels filter rod sections at a constant or at a variable frequency into a pneumatic conveyor which delivers the sections into the magazine of a receiver serving to store a supply of sections next to a filter tipping machine. The operation of the sender is interrupted for a fixed or for a variable interval of time after the sender propels a preselected number of sections. The intervals of operation and idleness of the sender are regulated in dependency on fluctuations of the quantity of sections in the magazine of the receiver. The frequency at which the sender propels the sections can be varied by varying the speed of a fluted rotor which transfers sections from a source to the sender, and the ratio of the intervals of operation and idleness of the sender is determined by several timing pulse generators which receive signals denoting the quantity of sections in the magazine and control the operation of a blocking device which can prevent the transfer of sections from the source into the sender.
