ABSTRACT:
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.
