Definitions

  • the invention relates to a sorter in the tobacco industry for sorting a stream of substantially flat and lightweight articles, comprising an optical inspection apparatus for finding non-conforming articles in the stream of articles and an article removing apparatus for removing the found non-conforming articles from the stream of articles, further comprising a substantially vertical duct, wherein the stream of articles enters the duct at an upper opening of the duct and the optical inspection apparatus and the removing apparatus are arranged in an inspection and sorting area of the duct.
  • the invention relates to a method of sorting substantially flat and lightweight articles in the tobacco industry, comprising the steps of feeding a stream of substantially flat and lightweight articles to an upper opening of a substantially vertical duct, inspecting the stream of articles by an optical inspection apparatus, removing non-conforming articles, which were found during inspection of the stream, by an article removing apparatus, wherein inspection and removal are performed in an inspection and sorting area of the duct.
  • Non-conforming articles in a stream of flat and lightweight articles which is in particular a stream of tobacco particles, which can be pieces of cut or fresh tobacco leafs, may result from the production process that is agriculture based. It is also possible that non-conforming articles come from other sources or are products to be sorted out from the tobacco product such as parts cut from stems. A typical size of the particles ranges from a few millimeters to a few hundred millimeters. Since tobacco is a relatively expensive raw material, it is desirable, to design the selection process in that it only removes the non-conforming articles. In other words, the sorting process should be as selective as possible to remove only the undesired articles from the stream of articles.
  • Document EP 1 838 464 B1 discloses a method and an apparatus for this purpose.
  • the disclosed apparatus comprises a sorting facility having an optical inspection facility and a removal facility for removing the non-conforming articles from the stream of articles.
  • the removal facility is gas driven. It removes the non-desired articles by pushing them with a gas jet in a direction, which is oriented transverse to the direction of the straight free falling movement of articles.
  • the inspection facility is preceded by an orientation facility for orienting the stream of articles through a centrifugal force. An air suction force performs a transition of the initial horizontal movement to the movement in the vertical falling direction of the articles.
  • the free falling articles are optically inspected.
  • the gas driven operation of the removal facility removes non-conforming articles.
  • a sorter in the tobacco industry for sorting a stream of substantially flat and lightweight articles comprising an optical inspection apparatus for finding non-conforming articles in the stream of articles and an article removing apparatus for removing the found non-conforming articles from the stream of articles, further comprising a substantially vertical duct, wherein the stream of articles enters the duct at an upper opening of the duct and the optical inspection apparatus and the removing apparatus are arranged in an inspection and sorting area of the duct, wherein the sorter is further enhanced by a blower apparatus, which is configured to generate a downwards air-flow in the vertical duct.
  • optical inspection refers to both, a visual inspection, for example using a camera, and a laser scanning process.
  • the design of the sorter is based on the following considerations:
  • the stream of articles comprises articles of different size and weight. In other words, there is a large size and weight distribution in the stream of articles. In a situation, when this stream enters a duct and the individual particles fall free in ambient air, the greater and heavier particles will fall faster than the smaller and lighter particles.
  • Each particle has an individual speed because its fall velocity under free fall conditions results from a balance between a downwards force, which is due to gravity and accelerates the particle, and the aerodynamic drag of the respective particle.
  • the sorter makes up for this deficiency by providing an airflow, which carries and in particular accelerates the particles downwards even in the detection and sorting area.
  • the airflow accelerates the articles through the inspection and sorting area.
  • the airflow carries away the small and light particles to give these particles a falling speed that is comparable to that of the greater and heavier particles.
  • the airflow compensates for the influence of the aerodynamic drag on the light particles.
  • the result of this technical measure is a situation in which all particles, which means the smaller and lighter particles as well as the greater and heavier particles, perform a uniform downwards motion in the detection and sorting area.
  • the delay time between detection and ejection of the non-conforming particles is almost the same for all particles, irrespective of their size and weight. Furthermore, there is no sideways movement of the particles. This positively influences the detection quality.
  • the advantageous effect is a significant enhancement of the sorting quality, which means that the probability that the air blast of the removing apparatus precisely hits the detected non-conforming article, increases significantly.
  • the sorter has an enhanced efficiency and provides better sorting quality.
  • the sorter in the tobacco industry is further enhanced that the inspection and sorting area comprises a first section and a second section, wherein the duct is split in a first part and a second part downstream the inspection and sorting area, wherein particles in the first section enter the first part and particles in the second section enter the second part and wherein the blower apparatus, the first part and the second part are configured in that a first air-flow in the first section and a second air-flow in the second section of the inspection and sorting area have substantially the same velocity field.
  • the air jet shifts it from the first section to the second section of the inspection and sorting area.
  • the particle is urged to perform an almost horizontal movement, which is preceded by the downwards movement and which is continued by a downwards movement.
  • the velocity field of the air which is conducted through the inspection and sorting area in the first and in the second section, is uniform.
  • the uniform velocity field is advantageous because there is no distortion, i.e. no turbulence or the like, in the downward streaming air.
  • Nonuniform motion could affect the ejection process in a negative way.
  • the result of the mentioned technical measure is again a more efficient sorting process.
  • the risk for undesired wrong matching of articles to the respective portion of the lower part of the duct is significantly reduced.
  • the sorter is enhanced in that the first section comprises the removing apparatus, which is configured to shift non-conforming articles from the first section to the second section, wherein the first part of the duct is for transporting conforming articles to subsequent treatment and the second part is for transporting non-conforming articles.
  • the first section comprises the removing apparatus, which is configured to shift non-conforming articles from the first section to the second section, wherein the first part of the duct is for transporting conforming articles to subsequent treatment and the second part is for transporting non-conforming articles.
  • the sorter is further enhanced by comprising an acceleration chute, which is arranged between a conveyor for transporting the stream of substantially flat and lightweight articles and the upper opening of the duct, wherein the acceleration chute is conical in shape and comprises an upper opening receiving the stream of articles from the conveyor and a lower opening having a smaller cross-section when compared to a cross-section of the upper opening.
  • the blower apparatus is configured in that it comprises air inlets which are arranged at or near to an upper opening of the acceleration chute.
  • the acceleration chute homogenizes the velocities of the different articles in the stream of articles. It is further advantageous to give the different articles some time and a trajectory having a certain length to adapt to the uniform falling velocity before the particles enter the inspection and sorting area and the ejection of the non-conforming articles is performed.
  • the acceleration chute further enhances the quality of the sorting.
  • the acceleration chute can be configured in that it accelerates the particles to a desired top speed, which can be a velocity, which is near to that of free falling velocity of the greater and heavier particles.
  • the conveyor has a transport surface carrying the stream of articles, wherein the transport surface bends from a substantially horizontal direction at a start portion of the conveyor to a tilted direction at an end portion of the conveyor, at which the stream enters the upper opening of the acceleration chute, wherein the end portion of the transport surface includes an angle with a vertical direction, which is between 30° to 70°, in particular between 55° and 65°.
  • the object is further solved by a method of sorting substantially flat and lightweight articles in the tobacco industry, comprising the steps of feeding a stream of substantially flat and lightweight articles to an upper opening of a substantially vertical duct, inspecting the stream of articles by an optical inspection apparatus, removing non-conforming articles, which were found during inspection of the stream, by an article removing apparatus, wherein inspection and removal are performed in an inspection and sorting area of the duct, wherein the method is further enhanced by the step of generating a downwards air-flow in the vertical duct by a blower apparatus, wherein the air-flow accelerates the articles in the inspection and sorting area.
  • the inspection and sorting area comprises a first section and a second section, wherein the duct is split in a first part and a second part downstream the inspection and sorting area, and wherein particles in the first section enter the first part and particles in the second section enter the second part and wherein a first air-flow in the first section and a second air-flow in the second section of the inspection and sorting area are generated by the blower apparatus and the first air-flow and the second air-flow have substantially the same velocity field.
  • the first section comprises the removing apparatus, which shifts non-conforming articles from the first section to the second section, wherein the first part of the duct transports conforming articles to subsequent treatment and the second part transports non-conforming articles.
  • the method is further enhanced by accelerating the stream of substantially flat and lightweight articles in an acceleration chute, which is arranged between a conveyor for transporting the stream of articles and the upper opening of the duct, wherein the acceleration chute is conical in shape and comprises an upper opening receiving the stream of articles from the conveyor and a lower opening having a smaller cross-section when compared to a cross-section of the upper opening.
  • the method comprises the step of transporting the stream of articles on a transport surface of a conveyor, wherein the transport surface bends from a substantially horizontal direction at a start portion of the conveyor to a tilted direction at an end portion of the conveyor, at which the stream enters the upper opening of the acceleration chute, wherein the stream of articles enters the upper opening of the acceleration chute at an angle, which includes 30° to 70°, in particular 55° to 65°, with a vertical direction.
  • the airflow can be injected using for example air inlets, at an upper opening of the acceleration chute or at an upper opening of the substantially vertical duct. This applies to all above-named embodiments.
  • Embodiments according to the invention can fulfill individual characteristics or a combination of several characteristics.
  • FIG. 1 there is a simplified schematic drawing showing a part of a sorter 2 in the tobacco industry.

  • the stream of articles 6 comprises conforming articles 8 and non-conforming articles 10.
  • the conforming articles 8 are for example parts of the tobacco leaf (lamina) while the non-conforming articles 10 may have other sources or can be parts of cut stems and the like.
  • Non-conforming articles 10 are non-tobacco related materials or, for example, discolored tobacco leafs.

  • the conveyor 12 has a transport surface 14, which is defined by an upper surface of, for example, the band of the band conveyor.
  • the band is guided via several guide pulleys 16. Again, only a few of the guide pulleys 16 are provided with a reference numeral for the sake of clarity.
  • the stream 4 of articles 6 is a monolayer of articles 6, which means that the articles 6 do ideally not overlap each other.
  • the sorter 2 further comprises an acceleration chute 18, which is arranged between the conveyor 12 and an upper opening 20 of a substantially vertical duct 22.
  • an optical inspection apparatus 24 which is configured for finding non-conforming articles 10 in the stream 4 of articles 6.
  • an article removing apparatus 26 for removing the found non-conforming articles 10 from the stream 4 of articles 6. Further details of the optical inspection apparatus 24 and the article removing apparatus 26 will be explained further below.
  • the stream 4 of articles 6 enters the substantially vertically oriented duct 22 at an upper opening 20, wherein directly downstream to this upper opening 20, there is an inspection and sorting area 28 (surrounded by a dashed line) in the duct 22.
  • the optical inspection apparatus 24 and the article removing apparatus 26 are arranged in this inspection and sorting area 28.
  • "comprising" with respect to the optical inspection apparatus 24 and the removing apparatus 26 means that optical inspection apparatus 24 and the removing apparatus 26, respectively, are configured or arranged in that detection and ejection of particles can be performed in the inspection and sorting area 28.
  • the device itself must of course not be entirely arranged in the inspection and sorting area 28.
  • the sorter 2 further comprises a blower apparatus 30, which is schematically illustrated and which is configured to generate a downwards airflow, which is indicated by arrows pointing downwards in FIG. 1 .
  • This downwards airflow is generated in the vertical duct 22, in particular in the inspection and sorting area 28.
  • the blower apparatus 30 is connected to a pipe system 32, which is only partly illustrated in FIG. 1 .
  • This pipe system 32 connects inter alia two air inlets 35, which are arranged at or near by an upper opening 21 of the acceleration chute 18, with the blower apparatus 30.

  • the conical shape and the reduction of the cross section accelerate the air, which is fed into the acceleration chute 18 via the air inlets 35 from the upper opening 21 to the lower opening 23.
  • This acceleration advantageously homogenizes the velocities of the different articles 6.
  • the articles 6 are in particular accelerated to a speed, which is the speed of the falling of the heavier articles. As a result of this, all articles have the same velocity, irrespective of their size and weight.
