Apparatus for feeding tobacco particles to one or two cigarette rod making machines has a magazine with a duct having an open lower end above the upper reach of an endless belt conveyor. The conveyor can be driven to advance tobacco particles in the duct toward an outlet of the magazine where the particles are removed by one or more rotors which are driven to move the particles upwardly and away from the upper reach of the conveyor before the particles are caused or permitted to descend into a hopper. The bottom portion of the hopper admits tobacco particles into one of two suction-operated pneumatic conveyors each of which supplies tobacco particles to a discrete rod making machine. The conveyor is driven at a first speed when the hopper supplies tobacco particles to a single rod making machine, and at twice the first speed when the hopper supplies tobacco particles to two rod making machines.

Apparatus for feeding tobacco particles to one or more consuming machines

Tobacco shreds are drawn from a magazine by a pneumatic conveyor pipe which delivers the shreds into the lower chamber of an air separator whose upper chamber is separated from the lower chamber by an air-permeable partition and is connected with the inlet of a suction generating device serving to draw an air stream through the pneumatic conveyor pipe. The velocity of the air stream in the pipe is maintained at a constant value by a flow restrictor which is installed in the inlet of the suction generating device and is adjustable by hand or by a servomotor receiving signals from a device which ascertains the velocity of air in the pipe by comparing the velocity of air in the second chamber with the velocity of air in the inlet of the suction generating device. The air separator has an outlet for periodical admission of batches of tobacco shreds from the first chamber into a duct which delivers the shreds into the distributor of a cigarette rod making machine.

Apparatus for supplying particles of tobacco to processing machines

A pneumatic conveyor draws particles of tobacco from a vibrating trough by causing an air stream to flow from its intake end, which is adjacent to the trough, to its intake end which is connected to a suction generating device. A cyclone separator is installed in the conveyor to segregate the particulate material from the air stream and to discharge such material into a duct which feeds the material by gravity to an intermittently operated cell wheel evacuator. The latter drops batches of particulate material into the magazine of the distributor in a cigarette rod making machine. The conveyor has an elongated diffusor which is disposed upstream of the cyclone separator to decelerate the air stream, and such diffusor is followed by an arcuate portion whose radius of curvature is greater than the radius of the cylindrical wall surrounding the chamber of the cyclone separator. This ensures reliable separation of acceptable particulate material and evacuation of smaller particulate material, including dust, from the separator by the suction generating device.
