Description

GERMAN

In devices for the pneumatic loading of several cigarette machines with cut tobacco it is known that the tobacco is the leading to the spreaders of the individual cigarette machines Pipelines are fed through a conveyor that brings the tobacco out of a common for all machines Removes storage container.

According to the invention, the conveyor is better known when feeding a common spreader Way divided into several lanes, and these conveyor belts leading to the conveyor tubes of the cigarette machines can be shut down individually.

Conveyors divided into individual lanes are known per se. But they only serve to bring from cut tobacco to the same spreader for just one cigarette machine.

By stopping the conveyor according to the invention, however, it is achieved that the individual Conveyors can be operated alternately, and with the continuous loading of several cigarette machines you can regulate the amount of tobacco supplied so that it corresponds to the mean value of consumption of all cigarette machines. So falls z. B. a cigarette machine, so will overall tobacco consumption decreased. It is also advantageous that the shutdown can then be loaded again Machine and the necessary return of the tobacco to the storage container is avoided.

Feeders are primarily suitable as conveyors, their spiked belts rising in a known manner cooperate with the tobacco layer height limiting known calculating wheels.

In the drawing, an exemplary embodiment of the subject matter of the invention is illustrated schematically, in which the conveyor feeds downstream vibration distributors before the cut tobacco is in the pneumatic pipelines. It shows

Fig. 1 is a plan view of a loading system for four cigarette machines and

Fig. 2 is a side view of the system, partly in section.

The cut tobacco 2 fed from the cut tobacco store in a known, not shown manner to the storage container 1 a of the feeder or conveyor 1 is dispensed by its drivers 1 & in a thin layer to the feed points of the vibration distributors 3 arranged below the dispensing point of the conveyor 1 . Staggered calculating wheels 5 and 6 comb the excess tobacco in a known manner up to the desired layer height and throw it back into the storage container la . The tobacco layer delivered to the distributor 3 at a uniform height is fed by these via the vibration distributor 4,

which connect like a staircase to the distributor 3 , given to rotating spiked rollers 7 , which are connected downstream of the distributors 3 and 4 in a vertical plane. A pressing device 8 presses the tobacco against the spiked rollers 7 . Beater rollers 9 beat the tobacco out of the spiked rollers 7 .

The knocked out tobacco 2 'falls on the object point or in the incident ports 10 of each cigarette maker associated pneumatic conveying conduit 11. The common driving of the vibration distributor 3 and carried 4 by a vibration conveyor system 12, which is driven in known manner by a crank drive. 13 The distributors 4 facing the spiked rollers 7 are pivotably mounted at the pivot point 14. At the ends of the channels 4 arranged below the channels 3 , bearing bolts 15 are fastened, into which fork yokes 16 engage rotatably. The fork yokes 16 are connected to lifting rods 18 of a lifting magnet 19 which can be moved up and down in guides 17. To return the tobacco 2 ″ to the storage container 1 a of the conveyor 1 , a conveyor belt 20 is arranged below the ends of the channels 4 which can be moved up and down.

In the drawing, a system for four cigarette machines is shown, so that four conveyors 1 are provided, the drive rollers 22 of which are driven by a common shaft 23 which is optionally driven in a manner not shown via a variable speed gear. Couplings 24 serve to releasably connect the shaft 23 to the drive rollers 22.

In general, all four cigarette machines are in operation, and the couplings 24 connect the drive shaft 23 to each of the drive rollers 22. Each conveyor 1 therefore promotes the tobacco 2 from the reservoir 1 a via the vibration distributors 3 and 4 and the spiked rollers 7 with the Beater rollers 9 in the

Ingress openings 10 of the pneumatic conveying lines 11. The lifting magnets 19 are under tension and pull the lifting rods 18 upwards. Through this. the vibration distributors 4 remain in the approximately horizontal, right-hand loading position. If tobacco is no longer required on a cigarette machine, the machine operator switches off the feed associated with this machine, the circuit of the lifting magnet 19 being interrupted and the coupling 24 for the associated conveyor being disengaged. Since the associated vibration distributors 3 and 4 continue to vibrate, the remaining tobacco still on them is taken over by the conveyor belt 20 for return. Since the associated conveyor 1 is at a standstill, no further tobacco is fed. Patent claims: 1. System for the pneumatic feeding of several cigarette machines with cutting Tobacco which is fed to the conveyor pipes leading to the machines by means of a conveyor which removes the tobacco from a storage container common to all machines, characterized in that the conveyor is divided into several lanes in a manner known when loading a common spreader and these to the conveyor pipes the conveyor belts (21) leading to cigarette machines can be stopped individually. 2. Plant according to claim 1, characterized in that the conveyors (21) are designed as adders whose rising spiked belts cooperate with the limitation of the tobacco layer height serving staggered calculating wheels (5,6) .
