ABSTRACT:
The present invention relates to reclaiming tobacco and paper from cigarettes. The apparatus of the invention entails a structural frame which carries a hopper intended to temporarily store a supply of cigarettes. Suitable conveying means connected to the frame convey the cigarettes consecutively from the hopper to sequential points of treatment. The tobacco is removed from each cigarette by an intermediate air jetting means connected to the frame at an intermediate station. Air from the jetting means is introduced into a receiving end of each cigarette as the cigarette is conveyed past the intermediate station so that the tobacco is ejected from the surrounding paper tube of the cigarette. Pneumatic aligning means connected to the frame at a first station consecutively aligns the cigarettes relative to the conveying means to assure direct proximity of the receiving end of each cigarette to the intermediate jetting means. Recovering means connected to the frame serve to collect tobacco and the remaining paper tube from each cigarette.
The method of the invention involves withdrawing cigarettes consecutively from a hopper and thereafter pneumatically aligning each cigarette relative to a conveying system. A receiving end of each cigarette is placed in axially abutting relation with a sealing plate supplied with air under pressure. A jet of air is directed from an orifice in the sealing plate through the receiving end of each cigarette to eject the tobacco from the surrounding paper tube of the cigarette. The paper tube remaining after the tobacco has been removed from each cigarette is pneumatically ejected into a chute. The tobacco removed from each cigarette and each remaining paper tube are separately conveyed to locations for further processing.
