System of devices for transporting rod shaped elements in production arrangement of tobacco industry

A system for transporting rod shaped elements in production arrangement of tobacco industry between machines making elements and machines processing elements in further operations, provided with a transitory store, to which rod shaped elements are delivered in compartment trays, comprising:

• a) a transitory store having an inlet zone that includes a plurality of fillers for compartment trays, to which rod shaped elements are mass-flow delivered by in-feed conveyors from making machines, wherein each making machine delivers to a separate one of said plurality of fillers,
• b) said transitory store further including an outlet zone having unloaders for unloading said compartment trays,
• c) said transitory store further including a stacking machine that places full compartment trays on a programmed station such as to deliver a full compartment tray to a respective one of said unloaders;
• d) out-feed conveyors leading from said unloaders that mass-flow deliver the unloaded rod shaped elements to processing machines, wherein each unloader delivers to a separate processing machine,
• e) each out-feed conveyor having situated there-along, an emptying hopper cooperating with a mobile filler for said compartment trays,
• f) wherein an end segment of said out-feed conveyor between said emptying hopper and a processing machine is adapted to deliver said rod shaped elements towards the emptying hopper when production assortment is changed,
• g) wherein said inlet zone of the transitory store further includes at least one filler for compartment trays for rod shaped elements mass-flow delivered by an in-feed conveyor from an unloader for one chamber trays, wherein each said at least one filler is connected to one unloader for one chamber trays, and
• h) wherein in the inlet zone of the transitory store there is situated at least one in-feed conveyor on which compartment trays are placed manually by an operator and in the outlet zone of the transitory store there is situated at least one out-feed conveyor from which compartment trays are collected manually by an operator.
