A compensating storage unit for compensating operating unbalances of manufacturing and paceting machines in a plant for producing cigarette packets, which plant comprises a system for directly feeding a stream of individual cigarettes disposed transversely of the stream by conveyor means continuously unidirectionally movable from at least one cigarette manufacturing machine to a machine for packeting the manufactured cigarettes, the unit comprising;
- a cylindrical body having its cylinder axis vertically disposed and having radially extending cigarette-storing compartments parallel to said vertical axis, each compartment having an open top and an open bottom and being dimensioned to permit cigarettes to be horizontally disposed in a cigarette pile one cigarette thick in the compartment between the top and the bottom an upper cigarette infeeding channel and a lower cigarette withdrawing channel respectively positioned above and below said cylindrical body in the area thereof including said open tops and bottoms of said compartments, said upper infeeding and lower withdrawing channels being vertically aligned one relative to the other, a movable device having uniformly spaced apart rigid catilever rods to take sucessive ones of said rods, perpendicularly to the vertical axis of the cylindrical body, into and along one of the radially disposed cigarette-storing compartments which is in vertical alignment with and between said upper infeeding and lower withdrawing channels, and intercepting means for stopping a stream of individual cigarettes, along said upper infeeding and lower withdrawing channels, relative to the open top and open bottom of said one cigarette-storing compartment, in synchronism with transitions of individual successive cigarette-storing compartments between said upper and infeeding and lower withdrawing channels;
- a kinematic movement transmission connected to said cylindrical body and to said movable device to transmit a continuous bidirectional movement to said cylindrical body rotating about its vertical axis for the disposing of cigarettes in each compartment during movement in one direction and for withdrawing them therefrom during movement in the opposite direction, and to transmit a continuous unidirectional movement to said movable device and cantilever rods;
- clutch means in said kinematic transmission upstream of said cylindrical body and said movable device;
- control means for deriving the bidirectional movement from the unidirectional movement, the control means being connected to the kinematic transmission between said clutch means and said cylindrical body;
- and
- movable sections of said upper infeeding and lower withdrawing channels, said movable sections being combined with said intercepting means and being actuated by said kinematic movement transmission in synchronism with completion of cigarette-storing and withdrawing phases in a cigarette-storing compartment and with inception of such phases in a successive-cigarette-storing compartment, the clutch means and the control means being controlled by the manufacturing and packeting machines.
