Abstract: A method of removing electrostatic charges from the tray (1, 1?) consists in supplying pressurized ionized air, first along the bottom (12, 12?) of the already turned over tray (1, 1?), and then, when unloading the tray (1, 1?), along its side walls (15, 15?) or the inner walls (14) of a compartment (13). The tray (1, 1?), made of dielectric material, protected against negative action of the electrostatic field, is provided inside with an insert (22, 22?) of conducting material, whereas the insert (22, 22?) may have different shapes. The device for unloading compartment trays (1) made of dielectric material is provided with an ionizer (10) disposed horizontally along the linear transporter (5), in the zone of feeding of the trays (1), whereas its nozzles (11) are turned in the direction of the inside of the bottom (12).

Abstract: Assembly having a plurality of conveyors (7, 8, 11, 23, 25, 29) and a variable capacity store (2) with one inlet (3) and one outlet (4) formed on two neighboring levels, a lower one (5) and an upper one (6), closed with a common back plate (9), fixed to a slide (13) making reciprocating movements, the concave surface (10) of which, on the interior side of the store (2) constitutes a conveyor (11), provided with a rotary arm, fixed to a slide (13), the axis of rotation of which is coaxial with a centre of curvature of the surface (10) of the back plate (9), and at the inlet (3) there is a swing mounted valve element (18) and a swing limiter (26) for displacing rod shaped elements (1), whereas at the outlet (4) there is swing mounted valve element (20). Moreover the invention presents a method of controlling mass flow of rod shaped elements in the store (2) and self-filling and self-emptying of the store (2) constituting a part of the assembly disposed in a production line of products of tobacco industry.

Abstract: Device provided for unloading compartment trays (2), filled with rod shaped elements (25), having an inlet conveyor (1) for full trays (2) and an outlet conveyors (3) for empty trays (2?) arranged parallel in one plane, and having a turning unit (4) for trays (2), provided with a supporting plate (6) and a turning unit (12) for trays (2?). It is provided with a linear transporter (14) for trays (2, T) situated in a plane perpendicular to the plane of conveyors (1, 3), provided with a movable arranged gripping unit (16) for trays (2) and a gripping unit (17) for trays (2?). Below a transporter (14) in the zone of operating of the gripping unit (16) there is situated an unloading conveyor (24) the end of which is situated at the inlet of an immovable throat (27).

Abstract: System having a transitory store (S), in the inlet zone (5) of which, there are disposed fillers (4) for compartment trays, to which rod shaped elements are delivered by in-feed conveyors (3) in form of mass flow from making machines (1), and each machine is assigned with a separate filler (4). In the outlet zone (9) of the store (S) there are disposed unloaders (8) for said trays, and rod shaped elements are delivered by out-feed conveyors (10) in form of mass flow to processing machines (2), and each machine (2) is assigned with a separate unloader (8). On the trajectory of each out-feed conveyor (10) there is situated an emptying hopper (11) co-operating with a mobile filler (12) for compartment trays. Moreover in the inlet zone (5) of the store (S) there is situated a filler (4?) for compartment trays, connected to an unloader (6) for one chamber trays with an in-feed conveyor (3?), and an in-feed conveyor (14), and in the outlet zone (9) there is situated an out-feed conveyor (15).
