  • a corresponding arrangement for the construction of at least two tobacco strands in a cigarette rod making machine and a method for the construction of at least two tobacco strands in a cigarette rod making machine are known from the EP 1 364 588 A1 the applicant known.
  • This object is achieved by a method for controlling the damming height of tobacco in a stowage, wherein the stowage height is detected by at least one sensor and controlled in dependence of the detected stowage height of the tobacco throughput of a subsequent conveying direction of the tobacco to the stowage conveyor member.
  • the inflow into the storage bays can be continuous, but it can also be an interrupted inflow.
  • interrupted inflow it makes sense to weight more the integral component in the controller, which may be a PID controller, for example.
  • the tobacco throughput is reduced.
  • the tobacco throughput is preferably increased when the damming height is increased above a predefinable value.
  • the tobacco throughput is expediently varied within a range of 10%, in particular 1% to 3%, by a predefinable standard throughput. Such a variation is sufficient for the expected filling fluctuations of the stowage time.
  • a faster control is possible if the size of the variation is changed depending on the damming height.
  • the maximum congestion level is reached to then increase the throughput in a kind of staircase function, but it is a continuous detection of the congestion allows and the flow rate of the conveyor organ continuously changed accordingly.
  • a linear relationship between the measured damming height and the throughput of the tobacco may be provided by the conveying member or another context.
  • An appropriate delay which may be predeterminable, may also be provided, that is, for example, as the congestion level increases, the flow rate is increased only after a delay of a fraction of a second or up to several seconds.
  • a method for building at least two tobacco strands from a single tobacco supply wherein at least two storage ducts, in particular directly, with the tobacco is fed from the tobacco supply, wherein from the at least two storage bays the tobacco is supplied in the direction of at least two Saugstrang cleanseern, the storage bays are arranged transversely to the conveying direction of the Saugstrang cleanseer, thereby developing a method for controlling the damming height of the tobacco has been used according to the invention and preferably described.
  • At least two very homogeneous tobacco strands can be produced simultaneously.
  • one of the storage spaces described therein is preferably filled with tobacco, for example, with a throughput that is promoted in the respective storage shaft 40 or 40 ', from 1% to 2% more than the other Stumbleacht.
  • the damming height can be controlled according to the invention, so that there is a substantially equal height of the two or more storage spaces. As a result, a very uniform strand structure of each strand is possible.
  • the tobacco is from the at least two storage compartments promoted to at least one flow area and then fed to the at least two Saugstrang devisern.
  • the method is used to control the stowage height of the tobacco for each stowage night.
  • the storage bays are alternately filled.
  • the filling frequency and / or the respective filling time of the storage ducts It is possible to specify the filling frequency and / or the respective filling time of the storage ducts. If the filling duration of the respective storage chutes is set as a function of the throughput of the conveying organs adjoining the storage chutes, very homogeneous tobacco strands can be produced.
  • the conveying members are removal rollers. It is particularly easy to compare the speed of the withdrawal rollers to control the filling.
  • the filling time of the respective storage shaft is set as a function of the respective damming height in the storage compartments, a very precise control is possible.
  • a storage height control device with at least one sensor for detecting the tobacco accumulation height in a stowage and with a control and / or regulating device, wherein by means of the control and / or regulating device of the tobacco flow of a conveying member located in the tobacco conveying direction downstream of the Stumbleacht connects, is controllable.
  • the conveying member is a removal roller.
  • a particularly simple control is possible if the speed of the removal roller is controllable.
  • Fig. 1 shows a schematic representation of an inventive arrangement for the construction of at least two tobacco strands.
  • essential parts of a tobacco distributor 10 are shown.
  • Fig. 1 corresponds in many respects or elements of Fig. 2 of EP 1 364 588 A1
  • the EP 1 364 588 A1 shall be fully incorporated in the disclosure of this patent application.
  • the other embodiments of the European Patent Application EP 1 364 588 A1 to vary according to the invention as the skilled person can quickly and easily understand after studying the present patent application and Fig. 1 of the present patent application.
  • the distribution element 39 may also be designed according to that of FIGS. 1 and 4 to 11.
  • two tobacco strands which can be prepared according to FIG. 1 of the present application, four tobacco strands can be produced, as in US Pat EP 1 364 588 A1 is described.
  • tobacco tobacco or uncoated tobacco such as, for example, Kretek
  • tobacco tobacco or uncoated tobacco is conveyed upwards by means of a steep conveyor 17 past a paddle roller 18 combing off excess tobacco and discharged into a chute 52 in a conventional manner from the tobacco supply.
  • the impeller 38 For portioning and / or separating any transport air is the impeller 38, in which the tobacco falls.
  • the impeller 38 discharges tobacco into a chute 70, to which a distribution element 39 adjoins in the conveying direction downstream of the chute 70.
  • the distribution element 39 which in Fig. 1 is designed as a kind of flap and by means of the tobacco 28, 28 'alternately in the storage spaces 40 and 40' is inserted, is designed as a movable flap.
  • Various other distribution elements 39 may also be provided, such as those described in the EP 1 364 588 A1 are described. It can also be provided 39 a distribution element, for example, in the EP 1 454 542 A1 is described.
  • tobacco 28 or 28' accumulates up to a storage height 27 and 27 'or a corresponding tobacco level.
  • the accumulating tobacco 28 or 28 ' is removed by a removal roller 42 or 42' from the storage bays 40 and 40 'and by means of a rollover roller 41 or 41' from the removal rollers 42, 42 'knocked out.
  • the tobacco then falls in the direction of a respective flow surface 44 and 44 '.
  • the tobacco is conveyed by means of an air flow 43 or 43 'onto the flow surfaces 44, 44' and to corresponding suction belt conveyors 50 and 50 'in a strand building unit 51.
  • suction belt conveyors 50 and 50' then tobacco cords 90 and 90 '.
  • the tobacco cords 90, 90 ' typically comprise more tobacco than is needed to produce a cigarette rod of uniform density. For this reason, excess tobacco is sheared off or cut off in the usual way just before wrapping the respective tobacco strands 90, 90 '. The excess is usually more than 10%.
  • the tobacco rod is produced, for example, in the conveying direction 91 or the Saugstrangizaer 50 and 50 'move in the conveying direction 91st
  • the function and design of the vibrating elements 60, 60 'and the vibrating stowage compartments 60, 60' reference is made to the full disclosure EP 0 919 143 A1 respectively. DE 197 52 717 A1 the applicant. The disclosure of these patent applications is intended to be incorporated in full in the disclosure of the present application.
  • the storage bays are at a predeterminable loading frequency of the storage bays 40, 40 'and a corresponding predetermined charging time, which can be predetermined for example directly via a machine control device 23 40, 40 'filled as evenly as possible.
  • a machine control device 23 40, 40 ' filled as evenly as possible.
  • the invention proposes to adapt the throughput of tobacco from the storage compartments 40, 40 'as a function of the damming height 27, 27' by varying the rotational speed of the withdrawal rollers 42, 42 '.
  • sensors 11-16 are provided, which are connected via cables 20, 21 to a controller 22.
  • the controller 22 is connected to the engine control device 23 via a cable 24. Signals may be sent from the controller 22 to the engine control device 23 as well as the reverse path.
  • the controller 22 receives the detected signals of the sensors 11-16 and converts them into a control signal, by means of which the speed of the removal rollers 42, 42 ', which are connected to the controller via cables 25 and 26, are controlled. This results in a regulation of the filling level or accumulation height 27, 27 'of the tobacco 28, 28' in the storage spaces 40, 40 '.
  • the controller can be, for example, a conventional PID controller whose parameters can be set by the skilled person by simple trial and error.
  • the intended sensors 11-16 may be simple sensors that merely indicate whether tobacco is present in the region of the respective sensors. They may be, for example, ultrasonic sensors or optical sensors. The sensors may also be designed to indicate a relatively precise position of the accumulation height 27, 27 'in the respective storage spaces 40, 40'. So it can position sensitive sensors such as a CCD array be predetermined. The accuracy can be in the range of a few millimeters. Depending on the type of sensors, the control parameters must then be set.
  • the distribution element 39 is also correspondingly variable to control and not set with fixed predetermined values. It is recommended in this case, in particular the charging time of the respective storage shaft 40, 40 'of the damming height 27, 27' adapt. The lower the damming height 27, 27 ', the higher the feeding time should be.
  • the loading duration of the respective storage compartments is fixedly determined for different lengths of time. This can be predetermined by fixed presettings, for example in the machine control device 23. The loading periods could then possibly be varied manually, if over a longer period of time, a change in the damming height 27, 27 'results, which is undesirable. However, it still makes sense to regulate at least one fine adjustment of the damming height 27, 27 'via the flow of tobacco from the stowage.
  • the mean value of the accumulation height 27, 27 'and / or the sum of the delivery rates or the tobacco flow of the removal rollers 42, 42' serves to control the delivery rate of the steep conveyor 17.
  • the removal rollers 42, 42 ' are preferably pin rollers whose Pins are inclined in particular to the direction of rotation of the rollers.
