Abstract
A conveyor system for bar-shaped articles, particularly cigarettes, in which said articles are conveyed in bulk from a channel disposed at a lower level to a channel disposed at an upper level by way of a channel comprising a first substantially U-shaped portion with its concavity facing upwards, and a second ascending portion, and in which an outer wall of said first portion and a wall of said second portion are defined by a single conveyor belt, while an inner wall of said first portion is defined by a rotatable drum.
Claims12
A conveyor system for bar-shaped articles, particularly cigarettes, comprising at least one inlet, an exit, a channel connecting said inlet to said exit, and ffed means disposed along said channel to move said articles along it from said inlet to said exit, said channel comprising a substantially vertical portion connected upperly to said exit, characterized in that said channel also comprises a substantially U-shaped curved portion with its concavity facing upwards, of which a first end communicates with said inlet and the second end communicates with the lower end of said vertical portion;
- and said feed means comprise a first conveyor belt defining an outer curved wall of said curved portion and a first wall of said vertical portion, a second conveyor belt mobile at the same speed as said first conveyor belt and defining, at least partly, a second wall of said vertical portion facing said first wall, and a rotatable drum constituting a support for said first conveyor belt along said curved portion and rotatable by said first conveyor belt;
- said drum defining an inner curved wall of said curved portion which faces and is parallel to said outer curved wall, and is in bar-shaped article delivery communication with said second wall.
A conveyor system for bar-shaped articles, particularly cigarettes, comprising at least one inlet, an exit, a channel connecting said inlet to said exit, and feed means disposed along said channel to move said articles along it from said inlet to said exit, said channel comprising a substantially vertical portion connected upperly to said exit, characterized in that said channel also comprises a substantially U-shaped curved portion with its concavity facing upwards, of which a first end communicates with said inlet and the second end communicates with the lower end of said vertical portion;
- and said feed means comprise a first conveyor belt defining an outer curved wall of said curved portion and a first wall of said vertical portion, a second conveyor belt mobile at the same speed as said first conveyor belt and defining, at least partly, a second wall of said vertical portion facing said first wall, and a rotatable drum constituting a support for said first conveyor belt along said curved portion and rotatable by said first conveyor belt;
- said drum defining an inner curved wall of said curved portion which faces and is parallel to said outer curved wall, and is in bar-shaped article delivery communication with said second wall;
- said rotatable drum comprising two mutually coaxial circular plates rotatably mounted about a horizontal axis and each having a peripheral cylindrical surface such that together the peripheral cylindrical surfaces define a cylindrical support seat for said first belt;
- and with each of said plates having on the surface facing the other plate, an annular shoulder which is coaxial to said axis and which annular shoulders together define said inner curved wall;
- and
- a further drum, coaxial to said rotatable drum, mounted in an angularly fixed position between the plates of the rotatable drum, with said fixed drum supporting a pulley for the second conveyor belt.
