Definitions

  • the invention relates to a conveying device for producing a tobacco monolayer supplied for further treatment from a continuously moving tobacco stream, comprising conveying means for feeding the tobacco stream and for separating the tobacco parts within the tobacco stream.
  • a "tobacco monolayer" in the sense of the invention is to be understood as a tobacco fleece consisting mainly of tobacco parts lying side by side or isolated (strips, ribs and the like obtained by pretreatment).
  • a tobacco monolayer is in many cases a prerequisite for successful further treatment of the tobacco during the course of a work process in preparation for the manufacture of rod-shaped end products in the form of cigarettes, filter cigarettes and the like.
  • Such further processing or processing steps are, for example, the sighting or spraying of the tobacco stream and in particular the scanning or opto-electronic scanning of the tobacco stream in connection with the detection and separation of foreign bodies, which are to be eliminated as early as possible, in order to disrupt the processing process and impair the quality of the Exclude final product.
  • the invention has for its object one, based on to create their conveying capacity as well as their distribution and equalization effect optimized conveying device.
  • the conveying means have at least two conveying elements which are successive in the conveying direction and can be driven at different conveying speeds and form a feeder and an outfeed conveyor.
  • a separation of the components of the tobacco flow along the conveying direction is most effectively achieved with a further development in that the conveying element arranged downstream in relation to the conveying direction has a higher conveying speed.
  • the feed element located upstream, in relation to the direction of conveyance is designed as an oscillating conveyor and that the discharge element arranged downstream has at least one conveyor belt.
  • the vibrating conveyor ensures loosening and transverse distribution of tobacco or a solution of tobacco clumps and the faster belt conveyor for stretching the tobacco flow along the conveying direction.
  • the vibratory conveyor is provided with a discharge edge limitation which generates a discharge surface profile on the discharge element.
  • this measure is that the belt conveyor, which is conveyed in particular by the speed difference between the continuously tobacco and the discontinuous or with interruptions Gap conveyors that deliver tobacco are largely closed in the gaps in the tobacco flow by the vibratory conveyor converting a concentrated or bar-shaped tobacco delivery into an area-wide diversified delivery over the discharge edges, which are graduated lengthways and transversely to the conveying direction, or via the discharge points that are thus widely distributed, so that an optimized, continuous self-contained tobacco monolayer is formed.
  • this chute edge limitation is composed of front and rear chute edge sections that extend from front to rear, with the chute edge sections being distributed in a step-like manner over the width of the vibratory conveyor.
  • the discharge edge limitation is designed in the form of a discharge fork.
  • the discharge edge delimiting the discharge fork is divided into numerous discharge edge sections which are alternately staggered in relation to the conveying direction and are connected by longitudinal edges. In this staggered arrangement, a more or less area-wide, closed distribution of the tobacco on the discharge conveyor is achieved by the tobacco being thrown off both from the rear and front edge sections and from the longitudinal edges of the discharge fork.
  • the discharge fork is provided with discharge tines which are delimited by discharge edge sections of the discharge edge converging in the conveying plane in the conveying direction.
  • each time the vibrating conveyor ejects vibrating vibrations a more or less closed surface section along the conveying direction is coated with tobacco on the conveyor.
  • discharge fork is, according to a further proposal, that the discharge edge course results from an outer end edge delimiting the bottom surface of the vibratory conveyor and a plurality of openings or slits in the bottom surface delimiting inner discharge edge sections which are adjacent to the conveying direction.
  • this alternative slot design a wide variety of different designs are possible.
  • the slots have an essentially rectangular cross section or are delimited by discharge edges which diverge in the conveying direction.
  • the described positive effects of the profiled discharge edge come into play particularly when the vibratory conveyor is inclined downwards in the conveying direction according to a further development, the inclination of the vibratory conveyor according to an additional proposal - based on an angle of attack in the size range of approximately 15 ° - up and down is adjustable.
  • An additional configuration according to which the vibratory conveyor is provided with a stepped bottom, exerts an additional detaching effect on the components of the tobacco stream that may still adhere to one another.
  • the conveying element following the vibrating conveyor consists of two conveying belts which form a conveying channel, are arranged underneath and ready and can be driven synchronously in the conveying direction. In this way, a ventilation effect is generated by the air entrained when the tobacco flow passes through the delivery channel. which has a beneficial effect on tobacco.
  • a foreign body separator is expediently arranged at the discharge end of the discharge element.
  • the conveying element which is inclined in the conveying direction is followed by a substantially horizontally running third conveying element which is designed as a conveyor belt and which has an identical or preferably lower conveying speed relative to the conveying element.
  • the advantage achieved by the invention is that the spreading of the individual components of the tobacco flow transversely to the conveying direction and the stretching of the tobacco fleece formed along the conveying direction in order to form a tobacco monolayer from adjacent or isolated components is achieved at a higher tobacco throughput, in connection with a downstream foreign matter separator, the desired sorting result with regard to the type, shape and size of the detected foreign matter is guaranteed.
  • the conveyor belts 8, 9 operated synchronously with common or own drive means have a higher conveying speed than the vibratory conveyor 6.
  • the vibratory conveyor 6 is provided with a stepped and optionally profiled floor 13 and is inclined downwards in the direction of conveyance (arrow 2) by about 15 ° , whereby the inclination can be adjusted up and down.
  • the entire conveyor element 7 is also set in the conveying direction with a lower inclination of approximately 10 °.
  • the foreign body separator 1 consisting of laser detectors 14 known per se for scanning the tobacco stream 3, a reference drum 16 which is color-matched to the tobacco, one of known ones in the Foreign body separator 1, integrated image processing processor (not shown) for recognizing and determining the position of foreign bodies 17 and blow-out nozzles 18 for selecting the foreign bodies 17.
  • integrated image processing processor not shown
  • the discharge end of the vibrating conveyor 6 which ends above the conveyor belt 8 of the belt conveyor 7 has such a discharge edge limitation 23 that the tobacco which is thrown off with each forward vibration of the vibrating conveyor 6 lies on the conveyor belt 8 on a surface with an approximately rectangular discharge surface profile in the outer boundary 24 distributed.
  • the discharge edge delimitation 23 is designed in the form of a discharge fork or is divided into numerous discharge edge sections 27 which are alternately staggered with respect to the conveying direction (arrow 2) and are connected by longitudinal edges 26. The distance between the longitudinal edges of the fork tines is expediently greater than the tine width.
  • the tobacco falls with each forward oscillation of the vibratory conveyor 6 from the front and rear discharge edge sections 27 running parallel to one another transversely to the conveying direction 2 and from the longitudinal edges 26 extending in the conveying direction in the form of a surface distribution on the conveyor belt 8 Quantities of tobacco in the successive forward vibrations of the vibratory conveyor 6 to each other without gaps, so that a virtually closed tobacco monolayer is formed.
  • the discharge fork formed by the discharge edge delimitation 223 is provided with discharge tines 228 which are delimited by discharge edge sections 229 converging in the conveying plane in the conveying direction 202.
  • the tobacco thrown off via the oblique discharge edge sections 229 merely results in a somewhat different distribution within the likewise rectangular discharge surface profile 224.
  • the discharge edge course or the discharge edge limitation 323 results from an outer end edge 331 delimiting the bottom surface of the vibrating conveyor 6 and a plurality of openings or slots 332 lying adjacent to one another transversely to the conveying direction 302 in the bottom surface delimiting inner discharge edge sections 333.
  • the tobacco With this configuration with rectangular slits 332, the tobacco finally falls on the conveyor belt 308 over the trailing edge 331 on each forward stroke of the oscillating conveyor 306 via the discharge edge sections 333 delimiting the slits transversely and along the conveying direction and the tobacco moved forward between the slits.
  • the slots 432 have a somewhat different or triangular configuration with discharge edges 434 diverging in the conveying direction, via which the tobacco within the discharge surface profile 424 reaches the conveyor belt 408 in a somewhat different distribution.
  • the mode of action is as follows:
  • the tobacco which is preferably fed over the full width perpendicular to the plane of the drawing onto the rear end of the vibratory conveyor 6, for example by an upward conveyor, is advanced by the oscillating movement in the direction of the arrow 2, with an additional detaching or separating effect on sheet parts still adhering when passing through the gradations 13 achieved and thus a separation and width distribution of the components of the tobacco flow is supported perpendicular to the plane of the drawing.
  • the tobacco flow is greatly accelerated and stretched in such a way that the sheet material and the foreign bodies 17 are also separated in the conveying direction.
  • the image processing processor By signaling very specific detectors 14, the image processing processor also recognizes the respective position of the foreign bodies 17 within the tobacco stream 3 and controls the corresponding blow-out nozzles 18 to selectively separate out the recognized foreign bodies 17.
  • the tobacco leaves that are blown out at the same time, particularly in the case of relatively small foreign bodies 17, are then re-sorted and returned to the processing process.
  • the variant shown in FIG. 6 differs from the first embodiment only in that the conveying means 107 is followed in the conveying direction 102 by a further, essentially horizontally running conveyor belt 122 which operates to optimize the tobacco monolayer of the tobacco fleece with the same or preferably a lower conveying speed than the conveying means 107 becomes.
  • the conveying means 107 is followed in the conveying direction 102 by a further, essentially horizontally running conveyor belt 122 which operates to optimize the tobacco monolayer of the tobacco fleece with the same or preferably a lower conveying speed than the conveying means 107 becomes.
  • the foreign matter separator 101 is then assigned to this additional conveyor belt 122.
