Definitions

  • the invention relates to a device for dosing tobacco in packaging-suitable portions, comprising a feed element for the tobacco and a device for forming and dispensing at least one tobacco portion suitable for packaging. Furthermore, the invention relates to a method for dosing tobacco, in particular moist tobacco, in packaging-suitable portions.
  • Snus tobacco is so-called oral tobacco (or tobacco mixtures) which is introduced into the mouth, directly or in a suitable packaging, eg a bag of cellulose or the like, the term tobacco not being exclusively the actual tobacco but also includes tobacco with additives, flavors or the like.
  • a suitable packaging eg a bag of cellulose or the like
  • tobacco not being exclusively the actual tobacco but also includes tobacco with additives, flavors or the like.
  • unpackaged snus tobacco it is filled into cans, boxes, combination packs or the like directly into these.
  • the actual consumable or ready-to-use portioning is done by the consumer himself.
  • the snus tobacco which is taken in packaged form, namely, for example, in individual sealed-edge bags or the like, must first be portioned and bottled.
  • the tobacco portions, the weight and size of each may vary and is usually in the range of milligrams and grams are separated from a continuously or intermittently supplied tobacco stream by means of metering devices and usually by means of so-called sealed edge bag machines, as shown in DE 10 2005 017 474 A1 are known, packed.
  • Dosing devices are known in practice, in which the feed element is a funnel, by means of which the tobacco is transported into the region of a device for forming and dispensing a packaging-compliant tobacco portion.
  • the known devices for forming and dispensing the tobacco portions usually comprise a pre-portioning chamber or expansion chamber, which is connected to the funnel via a hose or the like. Within the expansion chamber, the tobacco flowing out of the hopper is stored intermediately. Below the expansion chamber usually a micro cylinder is arranged. By retracting the piston, tobacco is virtually drawn from the expansion chamber into the cylinder, wherein the volume of the portioning chamber formed by the retracted piston corresponds to a tobacco portion suitable for packaging.
  • the expansion chamber When the portioning chamber is filled, the expansion chamber is moved relative to the microcylinder (or vice versa), so that the contents of the portioning chamber, namely a portion of tobacco, e.g. can be delivered to a transport chamber or the like.
  • This transport chamber may e.g. form a unit with the expansion chamber.
  • the transport chamber After filling the transport chamber with the metered tobacco portion, the transport chamber is moved to an issue position via an exit opening so that the tobacco portion is directed downwardly to a downstream device, e.g. the sealed-edge bag machine drops. While the transport chamber is above the outlet opening, the microcylinder can already be filled again with a next tobacco portion.
  • metering devices are suitable for single-lane and multi-lane sealed bag machines.
  • metering devices have the disadvantage that only free-flowing tobacco, ie tobacco with a low residual moisture content, is processable. In other words, only tobacco that has a residual moisture content of less than about 20% can be reliably processed. Also, tobacco with a residual moisture content of less than about 20%, the additives are mixed, difficult or impossible to process, since the additives, flavors and the like increase the moisture content, for example, by oils or the like. During the processing of such moist tobaccos, the tobacco adheres or sticks in particular in the region of the (partially bent) tubes as well as the microcylinders and leads after a short time to block the device and thus to a standstill of the subsequent seal bag machine.
  • the invention is therefore based on the object to provide a simple and reliable device for dosing tobacco, especially wet tobacco with a residual moisture content of greater about 20%. Furthermore, it is an object of the invention to propose a corresponding method.
  • the tobacco can be coated particularly reliably in the portioning chamber by turning the coating element back and forth, so that an exact filling / metering is ensured.
  • the turning back and forth can be done in a fast oscillating motion, which can also have different speeds for each rotation.
  • the portioning chamber is formed from two slide elements, which are spaced from each other and guided within a base plate, wherein the two slide elements are formed linearly toward and away from each other movable.
  • the two slide elements at the ends facing each other in each case a semi-circular contour in plan view, such that the Portion michssch is formed when pulled apart slide elements in plan view slot-shaped and co-pushed slide elements to form a cylindrical tobacco portion cylindrical.
  • this creates a volume which corresponds to the desired tobacco portion, and on the other hand achieves a shape of the tobacco portion which is particularly suitable for handling or further processing, ie for transporting the tobacco portion from the metering device into a packaging machine or the like, with the result that an impeding the dosing impurity or even clogging of the device can be avoided by tobacco residues.
  • An advantageous development of the invention is characterized in that the filling element is associated with a detection means for monitoring the level.
  • the devices shown in the drawing are used for dosing moist tobacco into packaging-suitable portions. Of course, the operations are also suitable for dosing tobacco with a residual moisture content less than 20% and of tobacco mixtures.
  • the in the FIG. 1 illustrated device 10 for dosing tobacco 11 in packaging suitable portions comprises a feed element 12 for the tobacco 11 and a device 13 for forming and dispensing at least one packaging tobacco portion suitable.
  • the device 13 for forming and dispensing tobacco portions can also be filled manually. In the context of automation, however, a feed element 12 is a matter of course.
  • the device 13 has a coating element 14 for applying tobacco 11 into a portioning chamber 15.
  • the coating element 14 can in further embodiments (see, eg FIG. 3 ) are also designed and set up to coat tobacco 11 into a plurality of portioning chambers 15.
  • the or each portioning chamber 15 is variable in volume, on the one hand for compacting the tobacco 11 and on the other hand for releasing the compressed tobacco portion.
  • each portioning chamber 15 is movable relative to the coating element 14.
  • the relative movement is preferably aligned linearly.
  • the portioning chamber 15 or the tobacco portion contained therein can be moved from a filling position B into an output position A and vice versa.
  • the device 10 in the region of the dispensing position A comprises an element 16 for dispensing the compressed tobacco portion.
  • the or each portioning chamber 15 is formed in the embodiment shown of two slide elements 17, 18. These slide elements 17, 18 are guided in a base plate 19. This means that within the base plate 19, for example, a groove 20 is formed, in which the two rod-shaped slide elements 17, 18 are guided.
  • the two mutually spaced slide elements 17, 18 are formed by suitable drive means, for example hydraulically, pneumatically, mechanically and / or via servo motors towards each other and away from each other movable.
  • the slide elements 17, 18 are preferably in the same, continuous formed groove 20 is arranged.
  • the sliding in the groove 20 back and forth slide elements 17, 18 have at the mutually facing ends 21, 22 each have a plan view (see, eg FIG. 3 ) semi-circular contour.
  • the ends 21, 22 are each concave, that is, curved inward.
  • the portioning chamber 15 when pulled apart slide elements 17, 18 in plan view slot-shaped (see, eg FIG. 2 ) and, when the slide elements 17, 18 are pushed together, in a plan view, circular to form a cylindrical body (see eg FIG. 3 below) is formed.
  • a filled or subdivided into the portioning chamber 15 tobacco portion can be formed into a cylindrical tobacco stick, wherein the size of the portioning chamber 15 in pushed together state of the slide elements 17, 18 is variable or adjustable and, for example, to form a tobacco stick with a length of about 14mm and a diameter of about 6mm is selected.
  • the dimensions of the tobacco stick may also vary and the ends 21, 22 may also have a different contour.
  • the guidance of the slide elements 17, 18 or other compression elements can be realized in a manner not explicitly shown, for example by guide rails, profiles or the like.
  • the portioning chamber 15 is laterally limited by the latter and downward by the base plate 19 in the described embodiment with the slide elements 17, 18 pushed together. Collapsed in this context means that the ends 21, 22 of the slide elements 17, 18 are in contact, so that the concave contours of the slide elements 17, 18 form a circle in plan view.
  • the portioning chamber 15 is bounded laterally on the one hand by the slide elements 17, 18 and additionally by the base plate 19, more precisely by the side walls of the groove 20.
  • Down the portioning chamber 15 is limited by the base plate 19.
  • the portioning chamber 15 is designed to be open in the region of the filling position B and the dispensing position A.
  • the structural design of the portioning chamber 15 can also be done in other ways, for example by the portioning chamber 15 after is bounded below by a separate plate or the like or by additional folding or sliding elements.
  • the portioning chamber 15 can be moved from a filling position B into an output position A. More precisely, the tobacco portion located in the portioning chamber 15 is movable linearly and preferably horizontally by displacing the slide elements 17, 18 from the filling position B below the coating element 14 into the dispensing position A above an outlet opening 23.
  • the outlet opening 23 is formed within the base plate 19.
  • the outlet opening 23 lies within the guide, namely the groove 20 for the slide elements 17, 18. In other words, the outlet opening is in the path of movement of the slide elements 17, 18.
  • the diameter of the outlet opening 23 corresponds at least to the diameter of the cylindrical in the dispensing position Portion istshunt 15 and is preferably slightly larger than the diameter of the final compressed cylindrical tobacco portion.
  • the coating element 14 is arranged on the base plate 19. In the filling position B for the portioning chamber 15, this is arranged directly below the coating element 14. In the dispensing position A of the portioning chamber 15, the coating element 14 is bounded or closed downwards by the base plate 19 or the slide elements 17, 18 guided in the groove 20, so that no tobacco 11 can be removed downwards from the coating element 14.
  • the coating element 14 is designed to be movable relative to the base plate 19. This relative movement can be carried out by moving the coating element relative to the stationary base plate 19, by moving the base plate 19 relative to the coating element 14 or by a superimposed movement of the coating element 14 and the base plate 19.
  • the coating element 14 is rotatably driven about an axis M in both directions for performing an oscillating movement.
  • the axis M is substantially perpendicular to the base plate 19.
  • the coating element 14 may also be circumferentially reciprocated in one direction or linearly. Also, the coating element 14 or its center axis M inclined to the base plate 19 may be aligned.
  • the coating element 14 is designed as a turnstile 24.
  • the turnstile 24 is formed from a cylindrical hollow body 25 as a shell part.

  • the hollow body 25 may have one or two chambers 27 (see, eg FIG. 3 ).
  • the turnstile 24 has four chambers 27 (see, eg FIG. 5 ).
  • Each chamber 27 serves to receive the supplied tobacco 11.
  • the chambers 27 are separated from each other by the partition walls 26.
  • the partitions 26 may extend only over part of the height of the cylindrical shell part, as is apparent from the FIG. 6 evident.
  • the partitions 26 may also extend over the entire height. Other designs and in particular the division of the interior and the design and arrangement of the partitions 26 are possible.
  • the coating element 14 and in the embodiment described the turnstile 24 is associated with a (not explicitly) illustrated detection means for monitoring the level.
  • the detection means can operate optically, mechanically or in another conventional manner and is preferably connected to a (likewise not explicitly shown) control.
  • the detection means is in operative connection with the feed element 12.
  • the feed element 12 is preferably a vibratory trough, but may also be a simple chute, a vibrating element or the like.
  • the controller can also be connected to the drives for the slide elements 17, 18 and for the coating element 14.
  • the element 16 for discharging the final compressed tobacco portion from the portioning chamber 15 may e.g. be a nozzle for ejecting by means of compressed air.
  • the element 16 may also be a mechanical plunger or the like. Other elements 16 for pushing, pushing, sucking, etc. are also usable.
  • Such devices 10 according to the invention can be used as a separate unit, for example as a retrofit kit for existing machines or plants.
  • the described devices 10 can also be part of, for example, a sealed-edge bag machine for producing sealing-edge bags filled with tobacco.
  • the described device 10, which is used for dosing tobacco is designed for a single-lane sealing bag machine, be adapted for multi-lane sealing bag machines.
  • the volume of the portioning chamber 15 is changed, namely in particular reduced, in order to compact the tobacco portion.
  • This change in volume is achieved by the pushing together of the slide elements 17, 18 (see, eg Figures 3 and 4c )).
  • a slide element 17 or 18 relative to the other slide element 18 or 17 or both slide elements 17, 18 can be moved towards each other.
  • the guidance of the slide elements 17, 18 takes place within a groove 20 of the base plate 19.
  • the portioning chamber 15 is closed at the top by a suitable device. This can be, for example, a lid-like device covering the groove 20 in this area.
  • the tobacco stick is moved further in the direction of the dispensing position A through the outlet opening 23 by the Slider elements 17, 18 are driven or moved together. As soon as the tobacco stick is above the outlet opening 23 (see, eg Figures 3 and 4d )), the tobacco stick is applied. This spreading can be done by the element 16 by blowing the tobacco stick. The tobacco stick can also be pushed out or otherwise removed from the portioning chamber 15.
  • the slide elements 17, 18 can be easily opened during dispensing or shortly before dispensing by the slide elements 17, 18 being moved slightly away from one another.
  • the tobacco portions dosed and dispensed in the described manner correspond to a portion suitable for packaging and form the content of a single sealed-edge bag.
  • the final compression of the precompressed tobacco portions and the displacement of the final compressed tobacco portions may be superposed in the dispensing position A in order to shorten the processing time.
  • the displacement of the portioning chamber 15 or the slide elements 17, 18 relative to the coating element 14 from the filling position B in the direction of the dispensing position A initially preferably takes place while maintaining the volume of the portioning chamber 15. That is, the tobacco portion before the actual final compression of the Filling position B is moved, so that a compression of the tobacco portion from the portioning chamber 15 back into the chambers 27 of the hub 24 is avoided during the final compression.
  • the tobacco 11 may be screened prior to feeding.
  • the tobacco 11 can optionally be sieved directly into the rotary star 24.
  • the tobacco 11 can also be screened onto the vibrating trough as a feed element 12.
  • the invention optionally provides that the filling level of the rotary star 24 is monitored in order to control the influx of tobacco 11 in the rotary star 24.
  • connection element for example a pipe
  • the inner diameter of the tube is slightly larger than the diameter of the outlet opening 23. This is especially important in the variant of ejecting the cylindrical tobacco portion (tobacco stick) by means of compressed air.
  • ejecting the tobacco portion by means of compressed air it may be advantageous to provide an additional volume of air in order to achieve a planar irradiation of the tobacco portion.
