Definitions

  • the invention relates to a sorting device for sorting small, lightweight objects defined by the preamble of claim 1, more particular to a seed sorting device.
  • the scope of application is for analysing, grading and sorting small, lightweight objects.
  • a sorting device for sorting small, lightweight object, especially seeds is commercially available on the market and known as iXeed.
  • the seed sorting device is configured to inspect each individual seed from a batch of seed and to remove seed with characteristics below required characteristics. In this way, the quality of a batch of seed is improved, which increases the value of the batch of seed.
  • the sorting device comprises an endless chain provide with trays along the length of the end less chain.
  • Each tray comprises an array of pockets in its top surface.
  • a pocket has a size and depth such that one piece of seed fits in the pocket and will normally stay in the pocket when the tray is moved back and forth in horizontal direction.
  • a pocket has a round, oval or elliptic shape such that after the pockets are filled with seed, the seed in the pockets have substantially the same orientation.
  • the tray further comprises air channels from the underside of the tray to a pocket. When air is blown in the air channel from the underside, seed that is in a pocket will be blown out of the pocket.
  • the trays are coupled to the endless chain and go around with a speed and passes each round subsequently a tray filling part, a seed surplus removing part, a visual inspection part, a selective seed removal part and a remaining seed removal part.
  • a tray filling part a continuous flow of seed is falling on each tray.
  • the seed surplus removing part a tray is moved in a direction perpendicular to the direction of the endless chain. In this way, the seeds are moved in the pockets and a surplus of seed is shifted to the edges of the tray to fall off from the tray. After the seed surplus removing part only seed is in the pockets and no seed is present on the top surface of the tray between the pockets. Then the tray with seed in the pockets passes the visual inspection part.
  • a camera In this part by means of a camera one or more images taken from the upper side.
  • Light sources positioned at the same side of the tray as the camera are used to improve the lighting of the tray and objects and to provide an image quality which is constant in time.
  • the images are analysed to determine for each pocket the characteristics of the seed in said pocket. Characteristics of a seed that could be used be: surface, length, width, symmetry, colour, dent, deformations, twists, mechanical damage, colour distribution, more than one seed in pocket, etc..
  • the characteristics are used to determine for each individual seed a quality measure. This quality measure is used to determine whether a seed in a pocket has the minimal desired quality.
  • a seed in a particular pocket has at least the minimal desired quality
  • the seed is blown out of the pocket by means of a nozzle into the space above the tray.
  • a puff of air from the nozzle is blown in the direction of the opening of a channel in the underside of a tray resulting in an air flow through the channel to the pocket.
  • a seed in a pocket is above the opening of the channel.
  • the puff resulting in the air flow causes the seed to move into the air above the tray.
  • a first suction unit above the tray sucks away the seed blown out of the pocket and collects the seed with the desired quality in a container.
  • the seeds not having the minimal desired quality which are still on the tray are removed from the tray and collected in another container. Then the empty tray is transported to the tray filling part again to start a subsequent sorting cycle.
  • the object of the invention is to provide an improved sorting device.
  • a sorting device is characterized in that, the blow unit is configured to press the outlets against the underside of a tray to prevent a flow of air from one outlet into air channels of pockets adjacent to the pocket
  • the invention is based on the recognition that a puff of air directed to an associated pocket to blow the object in the pocket into the suction device sometimes causes an airflow through the channel of an neighbouring pocket.
  • This airflow to a neighbouring channel could occur as the outlets of the blow unit and the inlet of an associated channel in the known device does not form a contiguous air channel.
  • the airflow could result in that the object in said neighbouring pocket is blown in to the airflow of the suction device. If said object didn't have the required quality, the object is erroneously added to a batch of objects. It could also happen that the object is moved such that is could not be blown out of the pocket in to the airflow of a suction device.
  • a solution to this problem is found in providing an arrangement which presses the outlets against the underside of a tray.
  • the underside of a tray will slide over the outlets of the blowing unit.
  • a puff of air will be blown in to the channel.
  • the amount of air that will not go through the air channel will be reduced significantly and the consequently said air has less force to move the object in a neighbouring pocket.
  • the outlets are movable between a first position and a second position, in the first position the outlets being positioned against the underside of a tray and in the second position the outlets being positioned above the path of the underside of a tray.
  • the blow unit comprises one or more spring elements to move the outlets to the second position.
  • the blow unit comprises a top surface including a first part and a second part
  • the first part of the top surface comprises the two or more adjacent outlets and forms a plane parallel to the path of the tray
  • the second part of the top surface is linked up to the first part and is a sloped with respect to the first surface wherein a border of the second part opposite to the first part has a position in the second position which is below the path of the underside of a tray.
  • the top surface further comprises a third part linked up to the first part and opposite to the second part, wherein part has a slope with respect to the first surface wherein a border of the third part opposite to the first part has a position in the second position which is below the path of the underside of a tray.
  • the top surface comprises grooves positioned between the outlets. This feature reduced the possibility that some air for a pocket will flow to a neighbouring pocket. If there is some space between the outlet and the underside, some air of a puff will flow through this space in to the groove. Even if the neighbouring outlet is at some distance from associated channel forming a small opening for an airflow from a neighbouring outlet, the pressure of said airflow will be reduced significantly by the groove.
  • the groves direct the airflow to another direction than the neighbouring pocket.
  • the blow unit comprises a guiding groove and a tray comprises guiding extension dimensions to pass through the guiding groove when said tray passes the blow unit.
  • the device further comprises an airflow reduction device configured for reducing airflow caused by the suction unit on the top surface of the tray. This feature enables us to reduce the chance that an object which is not blown out of a pocket is suck in to the suction unit.
  • the sorting device further comprises visual inspection device for inspecting characteristics of the objects, wherein the visual inspection device is arranged such that a tray comprising objects passes a beam of X-rays from a X-rays source to an imaging device, the tray comprises a top layer and a transparent layer positioned below said top layer, wherein the top layer comprises through holes forming at least a part of the volume of a pocket and the bottom of the pockets is formed by the transparent layer and the transparent layer comprises through holes forming the associated air channels.
  • the tray is configured to move the transparent layer with respect to the top layer such that in a first position the through holes of the transparent layer at one end are positioned such that objects in the through holes of the top layer cover the through holes of the transparent layer and in a second position the through holes of the transparent layer at said one end are positioned next to the through holes of the top layer.
  • the transparent layer comprises in the surface opposite to surface facing the top layer for each pocket a corresponding recess, wherein a cross section of the recess in the second position t overlaps at leas the through hole of the corresponding pocket.
  • each recess has a cylindrical shape with a cylinder axis, wherein the cylinder axes of the recesses coincide with the direction of the X-rays passing through the recess when the imaging device captures an X-ray image of the X-rays passing through the recess.
  • the method comprises providing a multitude of small lightweight object to an arrangement comprising all technical features of a sorting device according to the invention to obtain two or more batch of sorted lightweight objects.

  • the sorting section comprises two blow units 4, 4A, 4B and two suction units 5, 5A, 5B.
  • An endless chain not shown moves trays coupled to the endless chain between the blow unit 4 and the suction unit 5. In figure 1 only one tray 2 is shown. The tray follows a path 3 between the suction unit 5 and the blow unit 4.
  • the path of the underside of a tray is indicated by the arrow indicated with 3A.
  • the tray 2 comprises pockets.
  • the blow unit 4 is arranged for selectively blowing small lightweight objects out of the pockets.
  • the suction unit 5 comprises a duct with an opening for sucking the objects blown out of the pockets and is arranged to transport said objects to the desired container (not shown).
  • Each pair of blow unit and suction unit enables the sorting device to select object with a determined characteristic, i.e. seed quality, from a tray 2. For example, with two pairs of blow unit 4 and suction unit 5, three batches of objects with different quality can be obtained with one run.

  • the blow head 12A comprises a surface with outlets. If no tray is present between the blow head 12 A and the suction unit 5, the surface with outlets has second position which is between the path of the underside 3 a of the tray 2 and the suction unit 5. If a tray is moved between the blow head 12A and the suction unit 5, the surface with outlets is moved by the underside of the tray from the second position to a first position. In the first position, the surface with outlets coincides with the path 3a of the underside of a tray 2. As the spring elements forces the blow head 12A to the second position, the outlets are pressed against the underside of a tray. In this way is prevented that a flow of air from one outlet will flow into an air channel of an adjacent pocket.
