Definitions

  • the present invention relates to a chute for a sorting apparatus, said chute being provided with an inclined surface for guiding products, in particular granular products, towards a detecting and selecting system of the sorting apparatus while moving under influence of gravity. It also relates to an apparatus for sorting products comprising such a chute.
  • a sorting apparatus for in-line sorting of granular products is disclosed in European patent EP0952895 .
  • This sorting apparatus comprises a detection system, a removal system and a transport device having a sloped distribution surface, which is convex over at least a certain distance in the direction of travel of the granular products.
  • This transport device guides the products towards the detection and removal system such that products are analysed and selected while moving in a vertical downward direction.
  • the curvature of this convex distribution surface is equal to or slightly less than then curvature of the path the falling products would follow if this convex distribution surface would be absent.
  • this particular shape of the distribution surface forces the falling products to follow substantially congruent parabolic paths such that the position and speed of each falling product is predetermined, thereby rendering the process of analysing and selecting the falling products more easy.
  • this convex shape is present, there is still a large variation on the trajectories of the falling products such that the spacing between the removal system and the falling products cannot be minimised, thereby resulting in an unwanted removal of high-quality products.
  • the variation on the trajectory, i.e. position and speed, of each individual product renders the synchronisation of the detection system and the removal system more difficult.
  • This sorting apparatus also comprises a detection system, a removal system and a chute having a curved surface in the shape of a ski jump having a monotonic increase of the curvature of this surface towards the detection system.
  • This chute projects the products in an upward direction towards the detection and removal system such that the products are analysed and selected while moving in a horizontal forward direction. It is claimed that while gliding downwards along the curved surface of the chute the position of the products is stabilised due to the centrifugal forces acting thereupon. Although a more stabile product stream can be obtained, the projection of the products in a upward direction when leaving the chute introduces variation on the trajectory of projected products which makes the subsequent analysis and removal process more complex and less selective. Also here the position of the detection system makes it more prone to be dirtied by products having a trajectory, which differs from the mean path of the product stream, and consequently the quality of the detection system can be impaired.
  • the present invention aims to provide a chute that overcomes the above problems of the prior art solutions.
  • the invention aims to provide a sorting apparatus equipped with such a chute.
  • the present invention relates to a chute adapted for guiding a stream of products, moving under influence of gravity, in an essentially vertical downward direction allowing the analysis and selection of the products while in free fall.
  • the chute configuration also offers a better control over the trajectory of the falling products such that the spacing between the selecting system and the product stream can be minimised.
  • a chute comprising a first guiding element.
  • This first guiding element has a downwardly-curved surface over its entire length towards the detection system, i.e. along the direction in which the products propagate. If this surface is expressed by a function F 1 , this means in particular, that for the second derivative of this function F 1 it holds that / d ⁇ x 2 d 2 ⁇ F 1 ⁇ 0 over the complete width of said first guiding element.
  • DF1 hereby denotes the first derivative.
  • the chute comprises, in addition to the first guiding element, a second guiding element.
  • This second guiding element has a surface which is adapted for redirecting products which are propelled by the first guiding element towards the second guiding element and received by the second guiding element in an essentially vertical downward direction.
  • the surface of the second guiding element is upwardly-curved over at least a certain section along the movement of the product stream such that products propelled towards this upwardly-curved section are redirected by this upwardly-curved section in an essentially vertical downward direction.
  • the surface of the second guiding element is preferably shaped to be initially tangential to this mean velocity vector.
  • the second guiding element is convexly curved in the downward direction over its entire length.
  • the second guiding element has downstream an upwardly-curved section parallel with the product stream and upstream a downwardly-curved section.
  • the curvature of the second guiding element can be described by a spline function characterised by the following control points :
  • CP F 2 m x m x U n x n x m y T U m x ⁇ U T U n x n y
  • the present invention discloses an apparatus for sorting products, in particular granular products such as raisins, blueberries but also pellets e.g. plastic pellets.
  • the sorting apparatus comprises a supply system for providing products in a continuous stream to a chute as previously described.
  • This chute guides the supplied products, while moving under gravity, towards a detection system and a removal system, the chute comprising a first guiding element having a downwardly-curved surface and, optionally, a second guiding element as in the above-mentioned embodiments of the invention.
  • the detection system is positioned to analyse the products when moving in a substantially vertical direction.
  • the configuration of the sorting apparatus is such that the first guiding element is positioned on one side of the product stream and the removal system and, if present, the second guiding element is positioned at the opposite side of the product stream.
  • Fig. 1 represents a schematic view of a sorting apparatus according to an embodiment of the invention.
  • Fig. 2 represents a schematic view of the chute illustrating the parameters determining the shape and relative position of the first guiding element of the chute.
  • Fig. 3 represents a schematic view of a sorting apparatus provided with a first and a second guiding element according to an embodiment of the invention.
  • Fig. 4 represents a schematic view of the chute illustrating the parameters determining the shape and relative position of the first and second guiding element of the chute.
  • Fig. 5 represents a detailed schematic view of the chute illustrating a particular shape and relative position of the first and second guiding element of the chute according to the present invention.
  • the present invention discloses an apparatus for sorting products, in particular granular products such as raisins, blueberries but also pellets e.g. plastic pellets, which are supplied in a continuous stream.
  • the present invention discloses a chute for guiding the stream of products when moving in a vertical downward direction due to gravity, which can be used in such sorting apparatus.
  • FIG. 1 illustrates a sorting apparatus (10) according to a first embodiment of the present invention.
  • This apparatus for sorting products (1) comprises a supply system (3), at least one detection system (6,6'), a removal system (8) and a chute (P) which guides the stream of products, supplied by the supply system (3), towards the detection system (6, 6') and the removal system (8) while moving under influence of gravity.
  • This supply system (3) can be a conveyor belt, a shaker, a vibrating table or any transporting means known in the art.
  • the product granules are individually scanned by a detection system (6, 6'), preferably both from a front (6) and a rear position (6').
  • the detection system (6, 6') can comprise at least one light source directing a concentrated light beam (7, 7'), such as a laser beam, for scanning the products (1') and at a least one detector, such as a photo multiplier tube, but likewise a CCD camera is suitable as well, for receiving light reflected from the products (1').
  • a concentrated light beam (7, 7') such as a laser beam
  • a detector such as a photo multiplier tube, but likewise a CCD camera is suitable as well, for receiving light reflected from the products (1').
  • the sensed signal will be analysed and lesser quality products or foreign bodies will be detected.
  • a signal is given to the removal system (8).
  • this removal system (8) is a manifold of air pressure valves which can be opened on command.
  • an element (2) can be mounted above the supply system (3) at the point where the products (1) are transferred from the supply system (3) to the chute (P).
  • the products (1) when going from the supply system (3) to the chute (P) will be pushed again this element (2) such that products are more uniformly distributed over the product stream and a thinner product stream towards the chute (P) is obtained.
  • This element (2) can be a flexible flap mounted on a horizontal axis and which is made of rubber, plastic, leather or any kind of flexible material known in the art. This axis is located at the end of the supply system (3) adjacent the chute (P) and is perpendicular to the direction (9) in which the products (1) are being propagated.
  • the first guiding element (P 1 ) of the chute (P) has a downwardly-curved surface, i.e. the curvature of this surface is concave in the gravitational direction.
  • the first guiding element (P 1 ) has a surface which is downwardly-curved over its entire length towards the detection system (6, 6'), i.e. along the direction (9) in which the products (1') propagate. The products will fall from the supply system (3) on the chute (P) and glide downwards to the detection system (6, 6'), the position of the products being stabilised due to the centrifugal forces acting thereupon.
  • first guiding element (P 1 ) of the chute (P) illustrated in Fig. 1 thus has a downward parabolic surface such that the chute is downwardly sloped over its entire length along the propagation direction (9) of the products (1').
  • first guiding element (P 1 ) of the chute (P) is shaped such that when the falling products (1') leave the chute (P), they are propelled downward towards the detection system (6, 6').
  • each granule normally has a nominal speed of approximately 2 m / s .
  • the product goes into free-fall thereby describing a parabolic curve.
  • the products (1') will finally propagate in an essentially vertical downward direction. From this point onwards products (1') will be analysed by the detection system (6, 6'). As shown in Fig.1 , the concentrated light beam (7, 7') of the detection system (6, 6') is directed to the product stream where propagating in an essentially vertical direction.
  • the chute (P) is positioned below the product stream to carry the product stream. Due to this configuration one can position the removal system (8) downstream the product stream and opposite the side where the chute (P) is placed. The removal system (8) can even be positioned such that the distance between the removal system (8) and the product stream is minimised. Given the fact that the product stream is more confined, the average distance between the removal system (8) and the free-falling products can be greatly reduced.
  • the removal system (8) comprises a manifold of air-pressure valves, which often is the case, the effective removal area of one such valve at this short distance from the falling product is, contrary to prior art sorting apparatus, no more much larger than the size of a typical granule such as a raisin or a peanut. As a result the false reject, i.e. the amount of good product which has been removed, is considerably reduced.
  • a detailed description is given below to determine the configuration of the first guiding element (P 1 ) of a chute (P) according to a first embodiment of the invention, the shape of which can be selected according to the description given below.
  • Fig.2 illustrates the mathematical modelling of this first guiding element (P 1 ).
  • the curvature of this first element (P 1 ) is fully described by a B-spline P 1 .
  • the origin of this B-spline function is placed on the outgoing point of the first guiding element (P 1 ), i.e. at is lowest point E.
  • P 1 describes a cubic spline, i.e. the number of knots minus the number of constraints is four.
  • the current invention is however not limited to this particular mathematical formulation, as long as the first guiding element (P 1 ) is downwardly sloped over its entire length along the propagation direction (9) such that the products (1') are leaving the first guiding element (P 1 ) in a direction which is equal or less than the horizontal direction X as shown in Fig.1 .
  • F x M ⁇ g ⁇ cos arc ⁇ tan d ⁇ F 1 d ⁇ x , where g is the acceleration due to gravitation. Because one is only interested in the speed of a granule at the point where it leaves the first guiding element (P 1 ), M can be assumed to be one, i.e. the speed is independent of mass.
  • the dimensions of the first guiding element are selected from the following ranges :
  • the angle ⁇ should preferably be between 70 and 90 degrees, preferably selected from the range 80 to 90 degrees, more preferably this angle is about 90 degrees.
  • the angle ⁇ is selected from the range 20 to 85 degrees, preferably selected from the range of 40 to 85 degrees and is preferably about 80 degrees.
  • the knot ( ⁇ , ⁇ y ) is varied to such an extent that the first guiding element (P 1 ) of the chute (P) is concave in the downward direction.
  • the knot ( ⁇ , ⁇ y ) is taken to be (0.0779m, 0.1279m), measured in an XY reference system as depicted in Fig.2 .
  • Fig.3 illustrates a sorting apparatus (10) according to another preferred embodiment of the present invention.
  • the sorting apparatus comprises a supply system (3), a detection system (6,6'), a removal system (9) and a chute (P) which guides the stream of products, supplied by the supply system (3), towards the detection system (6, 6') and the removal system (8) while moving under influence of gravity.
  • This supply system (3) can be a conveyor belt, a shaker or any transporting means known in the art.
  • the product granules are individually scanned by a detection system, preferably both from a front (6) and a rear position (6').
  • the detection system can comprise a laser and a photo multiplier tube, but likewise a CCD camera is suitable as well.
  • the sensed signal will be analysed and lesser quality product or foreign bodies will be detected.
  • a signal is given to the removal system (8).
  • this removal system (8) is a manifold of air pressure valves which can be opened on command. This allows the rejected element (1") to be blown out of the product stream as soon as it enters the cone of high pressured air produced by such a valve, while the accepted elements (1"') continue their movement.
  • the present invention is however not limited to an air pressure based removal system.
  • a element (2) can mounted above the supply system (3) at the point where the products (1) are transferred from the supply system (3) to the chute (P). The products (1) when going from the supply system (1) to the chute (P) will be pushed again this element (2) such that products are more uniformly distributed over the product stream and a thinner product stream towards the chute (P) is obtained.
  • the chute (P) comprises a first guided element (P 1 ) as previously discussed, which has a downwardly-curved surface, i.e. the curvature of this surface is concave in the gravitational direction, and further a second guiding element (P 2 ) having an upwardly-curved surface, i.e. at least a part of its surface is convex in the gravitational direction.
  • the products will fall from the supply system (3) on the first guiding element (P 1 ) and glide downwards to the second guiding element (P 2 ).
  • the chute illustrated in Fig.3 thus comprises upstream a first guiding element (P 1 ) having a downward parabolic surface and downstream a second guiding element (P 2 ), at least one section (P 2A ) thereof has an upward parabolic surface.
  • both guiding elements (P 1 , P 2 ) are positioned with respect to each other, such that when the falling products (1') leave the first guiding element (P 1 ) they are propelled towards the second guiding element (P 2 ) to be received thereby (P 2A ).
  • each granule normally has a nominal speed of approximately2 m / s .
  • the product goes into free-fall thereby describing a parabolic curve.
  • the product will reach the second guiding element (P 1 ) at a predetermined point (U). From that point onwards the second guiding element (P 2 ) will guide the product to an essentially vertical downward direction.
  • the receiving section (P 2A ) of this second guiding element (P 2 ) is shaped to be initially parallel with the mean velocity vector of the incoming product stream thereby minimising the risk of the products to bounce back upon impact with the second guiding element (P 2 ). Due to its convex shape the second guiding element (P 2 ) first receives the products at point (U) and then redirects them in a vertically downward direction.
  • the velocity vector (V) of the propelled products as determined by the curvature of the first guiding element (P 1 ) is gradually redirected from a more horizontal direction to a vertical direction thanks to the smoothly curved surface of the second guiding element (P 2 ) resulting in a free fall of the products with well controlled position and speed.
  • the trajectories of the falling products are better controlled thereby reducing the spread thereof.
  • the second guiding element (P 2 ) will substantially minimise the spinning of the falling products such that shape detection of these products can be done more accurately.
  • the second guiding element (P 2 ) need only to have a section (P 2A ) with a downwardly curved surface from impact point (U) downwards. All trajectories of the propelled product should reach the second guiding element (P 2 ) at this point (U) or below. However some outlier products may have a deviating trajectory which leads them above this point (U). These products will then be lost.
  • a second section (P 2B ) can be placed in the second guiding element (P 2 ) at a position above this point (U).
  • This upstream section (P 2B ) preferably has a downward parabolic shape as shown in Fig.3 .
  • this second section (P 2B ) will prevent such outliers from travelling beyond the second guiding element (P 2 ) by either bouncing them back to the first guiding element (P 1 ) or by guiding them directly to the downstream convex section (P 2A ).
  • this section (P 2B ) can be designed to have a straight shape which is more or less parallel to the trajectory of the incoming products. The latter alternative might be easier to manufacture as the second guiding element (P 2 ) can then be constructed from a straight plate only requiring one end of it (P 2A ) to be curved according to the required specifications.
  • the first guiding element (P 1 ) is positioned below the product stream to carry the product stream, while the second guiding element (P 2 ) is positioned downstream and above the product stream to prevent the propelled products to move further in horizontal direction. Due to this configuration one can position the removal system (8) downstream and at the same side as the second guiding element (P 2 ) as it this second guiding element (P 2 ) will prevent residues or products being deposited on the removal system (8).
  • the removal system (8) can even be positioned parallel in vertical direction with the second guiding element such that the distance between the removal system (8) and the product stream is minimised. Given the fact that the product stream is more confined the average distance between the removal system (8) and the free-falling products can greatly reduced.
  • the removal system (8) comprises a manifold of air-pressure valves, which is often the case, the effective removal area of one such valve at this short distance from the falling product is, contrary to prior art sorting apparatus, no more much larger than the size of a typical granule such as a raisin or a peanut. As a result the false reject, i.e. the amount of good product which has been removed, will be considerably reduced.
  • a detailed description is given below to determine the configuration of a chute (P) according to this second aspect of the invention: the shape and the relative position of each guiding element (P 1 , P 2 ) can be selected according to the description given below.
  • Fig.4 illustrates the mathematical modelling of the both elements (P 1 ,P 2 ).
  • the curvature of the first element (P1) is fully given by a B-spline F 1 .
  • the origin is placed on the outgoing point of the first plate.
  • F 1 describes a cubic spline, i.e. the number of knots minus the number of constraints is four.
  • the present invention is however not limited to this particular mathematical formulation.
  • n x n y and m x m y are the rightmost (n) and leftmost (m) points on the second plate ( P 2 ), respectively.
  • the control points CP F 2 ensure that the outgoing direction of granules along P 2 is vertical.
  • the vertical distance between point (I) and point (m), i.e. the height of the chute (P), can vary between 0.1m and 1.2m.
  • the height of the first guiding element (P 1 ), measured between point (I) and point (E), is preferably between 0.3m and 0.8m and the height of the second guiding element (P 2 ), measured between point (n) and point (m), is preferably between 0.05m and 0.4m.
  • the horizontal distance between point (I) and point (m), i.e. the width of the chute (P), can vary between 0.15m and 0.7m.

  • This selection of parameters thus results in a second guiding element (P 2 ) of the chute (P) having only the downstream section (P 2A ) curved.
  • This embodiment is illustrated in Fig.5 .
  • the angle ⁇ , indicative for the slope of the first guiding element (P 1 ) near the supply system (3) and measured counter clockwise relative to the horizontal axis, should preferably be between 70 and 90 degrees and more preferably about 80 degrees.
