Benefits of technology
The present invention is a tobacco feed unit for a machine used to manufacture tobacco products. The unit includes a path for shredded tobacco to be fed towards a forming unit where tobacco particles are formed into a continuous stream. The invention also includes sensing means along the path to identify the type of tobacco before it reaches the forming unit. This allows for easy switching between different types of tobacco without the need for manual adjustment of the machine settings. The technical effect of this invention is improved efficiency and flexibility in the manufacturing process for tobacco products.
Problems solved by technology
It will often become clear when the machine has already produced a certain quantity of cigarettes, for example from systems monitoring the quality of the single cigarettes turned out, that the tobacco is unsuitable and the product must be discarded, incurring considerable loss of time and materials.
The error in question is frequently attributable to the fact that different types of tobacco can often be so similar in color as to be indistinguishable to the eye of an operator.

Embodiment Construction
[0020]With reference to FIG. 1, numeral 1 denotes a machine, in its entirety, for manufacturing tobacco products 2 such as cigarettes, by way of example.
[0021]The machine, or cigarette maker 1, is equipped at the upstream end with a tobacco feed and transport section 3 by which a mass of shredded tobacco 4 is formed into a continuous flow of tobacco particles. The components of the feed and transport section 3 are housed in a vertically extending enclosure 5 delimited uppermost by a horizontal wall 6 and on either side by two vertical walls 7.
[0022]Shredded tobacco 4 is directed into at least one header chamber 11 surmounting the horizontal wall 6 and connected by way of at least one inlet duct 12 to a primary processing section denoted 13, shown schematically in FIG. 2. Leaf tobacco fed into this same section 13 is processed and conveyed by pneumatic means (not illustrated) along the duct 12 and into the chamber 11.
[0023]The section denoted 3, the inlet duct 12 and the outfeed stag...

In a cigarette maker, shredded tobacco passes through a feed and transport section toward a unit by which divided particles of the tobacco are gathered into at least one stream providing the filler for cigarettes. By positioning one or more sensors either along the feed and transport section or at a point upstream, relative to the feed direction of the tobacco, it becomes possible to identify the type of tobacco being handled at any given moment, so that when production schedules include a changeover from one brand to another, supervisors can be certain that the right type of tobacco has been selected, and ensure that different types of tobacco will not mingle.
Description
BACKGROUND OF THE INVENTION[0001]The present invention relates to a unit and a method for feeding tobacco in a machine by which tobacco products are manufactured.[0002]The invention finds application to advantage in the art field of complete lines for the manufacture of tobacco products, and in particular cigarettes.[0003]In a conventional line for manufacturing tobacco products, shredded tobacco passes along one or more ducts from a primary processing section into the feed and transport section of a cigarette maker; a partial vacuum is generated in the ducts, drawing the tobacco first into a header chamber, then from the header chamber into a feed chamber. The tobacco is directed en masse from the feed chamber into a carding unit and thereafter into a descending duct, or chute. Emerging at the bottom of the chute, the tobacco is transferred toward the bottom end of an ascending duct or chimney, enclosed at the top end by at least one moving conveyor consisting in an air-permeable a...
