Description

Technical Field

[0001] The present invention relates to an object sorting system and an object distributing and conveying device for distributing and conveying a plurality or a large number of objects, and a system comprising such a device. Background Art

[0002] It is well known to sort objects in a large number of objects (e.g., grains) by means of a rotating drum or roller, which has a pocket inside. The drum rotates around a substantially horizontal axis while being aligned with its longitudinal center axis, which coincides with the horizontal axis. Objects such as particles are fed to one end of the drum, and when the drum rotates, the particles are lifted because they are captured in the pocket. The size and dimensions of the pocket are suitable for receiving one object respectively. In the bottom of each pocket, an opening is provided to the outer surface of the drum, so that, for example, light can be sent from the outside of the drum through the opening to the object and detected on the inside of the drum or reflected to be detected on the outside of the drum, and vice versa. In this way, the objects in each pocket can be illuminated with light, so that a reflection or transmission spectrum can be obtained. From the spectrum, the characteristics of the object can be obtained, which can be used to sort or subdivide the large number of objects based on the characteristics. Then, one or more collectors can be placed near the drum so that after characterization, a designated fraction (fraction) is received based on the pulses of the ejector via a detector system. Such a drum and a machine comprising such a drum are disclosed in WO 2004 / 060585.

[0003] Another known sorting solution is to make a large stream of objects fall from a ledge, similar to a waterfall. A camera or a group of cameras detects the characteristics of the object during the falling process, and the ejector unit is arranged to eject objects with certain detected characteristics during the falling process. In this way, the ejected objects are sorted out from the original large stream of objects. The disadvantage of this solution is that even with the optimized fluid jet, it is quite inaccurate, because for each ejection, several adjacent objects are also ejected together with the object with a specific characteristic. Therefore, most of the ejected objects may not have the specific characteristics that trigger the ejection, so that the ejected object group has mixed characteristics. At the same time, many objects that should not be ejected are also ejected by this method. This has an adverse effect on the throughput of the system and the ability and degree of accurately sorting out objects with different characteristics, because, for example, only a small part can be separated. In addition, this system requires a lot of space because the camera equipment is bulky and requires a complex control system. The size of the camera equipment causes the system to have to implement a waterfall design, in which all objects are conveyed in the same plane and the camera equipment extends to the entire conveying area. Furthermore, the camera equipment - which may include one camera for each lane or section of the conveying area - needs to be placed relatively far away from the object in order for the wide-angle lens to correctly identify the characteristics that form the basis for sorting, thereby capturing the entire width of the material flow. Furthermore, the object needs to be monitored from both sides by the camera in order to correctly identify the characteristics. Therefore, a disadvantage of camera-based sorting systems is that they require a lot of space to achieve the desired results.

[0004] To address this problem, a system proposed in WO 2019 / 054932 has been developed. In the disclosed system, a plate with channels is used to convey and separate small portions of objects, whereby the objects are sorted based on timing and speed measurements and optical readings. However, such a system is limited in capacity.

[0005] The present inventors have recognized that there is room for improvement in this area. Summary of the invention

[0032] The following description is directed to an object dispensing and conveying apparatus for forming part of a system for sorting objects having certain measured properties from a plurality of objects. Such objects may be organic or inorganic, such as grains, pellets, lentils, nuts, tree nuts, pulses, recyclables, minerals, metals, plastics, etc.

[0033] Figure 1 An object distribution and conveying system according to an embodiment is schematically depicted.

[0034] The object dispensing and conveying system includes a dispensing and conveying device 1000 for dispensing and conveying a plurality of objects as described above.

[0035] The device 1000 includes an inlet manifold 300 for receiving and conveying objects to a sorting unit 100 for sorting the objects. The object distribution and conveying system may therefore include a plurality of sorting units 100. Each sorting unit 100 may be configured to sort a portion of the objects (e.g., the objects conveyed to the sorting unit 100) by means of the inlet manifold 300. Figures 6 to 10 As described, the sorting unit 100 may be adapted to sort the plurality of objects into fractions based on at least one characteristic associated with the objects.

[0036] An inlet manifold 300 may be connected to the sorting unit 100 for conveying and distributing the objects to the sorting unit 100. The sorting unit may form an object sorting system.

[0037] In one embodiment, the device 1000 may include more than one inlet manifold 300. Therefore, the device 1000 may include one or more inlet manifolds 300 as described above. Therefore, multiple inlet manifolds may be included in the device 1000, each inlet manifold including a guide device and an outlet for conveying objects to the sorting unit. In one embodiment, the first inlet manifold may be arranged above the second inlet manifold relative to the vertical reference direction. In one embodiment, multiple inlet manifolds may be arranged above each other relative to the vertical reference direction. In one embodiment, multiple inlet manifolds may be arranged directly above each other relative to the vertical reference direction.

[0038] The sorting unit 100 may comprise a pneumatically operated ejector unit. Thus, the sorting unit may be operated by means of air supplied by a pneumatic system 125. Thus, the ejector unit is connected to the pneumatic system 125 and is provided with pressurized air from the pneumatic system 125. The pneumatic system may be operably connected to a control system 120. The control system may comprise a control unit 122 and a controller interface 121 configured to receive input from a user for controlling the sorting unit 100. The control system 120 may be configured to control the pneumatic system 125. The ejector unit may be provided with a valve controlled by means of the control system 120 to discharge air through the ejector unit.

[0039] Figure 2 The object dispensing and conveying apparatus 1000 is depicted in greater detail.

[0040] In the depicted embodiment, the apparatus 1000 includes an outlet manifold 400 for conveying the objects out of the sorting unit. However, it is conceivable that the objects are conveyed directly from the sorting unit to a separate vessel, conduit or container that does not form part of the apparatus 1000. However, as will be described with reference to Figure 4 As further elaborated, the outlet manifold 400 according to the invention enables the collection of sorted objects in a more compact and clean manner. It is also conceivable that the inlet manifold is in the form of a separate channel extending to each sorting unit. Such an inlet manifold can also be combined with the outlet manifold according to the invention.

[0041] In the depicted embodiment, the device 1000 further comprises a support structure 500. The support structure 500 is adapted to carry and support the sorting units. Thus, the support structure 500 is adapted to hold the sorting units. Preferably, the support structure 500 is adapted to releasably hold the sorting units so that maintenance and adjustment of the number and position of the sorting units can be easily performed. Thus, a modular system is achieved in which sorting units can be removed and added. Thus, the conveying and distribution system can be considered to be a modular conveying and distribution system.

[0042] In one embodiment, the support structure 500 is a floor-standing support structure. In one embodiment, the support structure 500 is a free-standing support structure. Therefore, the support structure 500 can be provided with legs for standing on the floor.

[0043] Further references Figure 2 , the inlet manifold 300 and / or the outlet manifold 400 may be mounted to the support structure 500, whereby the support structure 500 is adapted to carry and support the inlet manifold 300 and / or the outlet manifold 400. Preferably, the inlet manifold 300 and / or the outlet manifold 400 are releasably mounted to the support structure 500. This makes it easier for maintenance personnel to maintain and inspect the device.

[0044] In one embodiment, the support structure 500 is adapted to carry the pneumatic system 125. The pneumatic system 125 may thus be mounted to the support structure 500.

[0045] Figure 3 The inlet manifold 300 is depicted in greater detail. Figure 3 In FIG. 3 , the housing 340 of the inlet manifold is made transparent to show the interior of the inlet manifold 300 .

[0046] The inlet manifold 300 comprises one or more feeder inlets 301, 302 for feeding objects into the inlet manifold 300. Therefore, the one or more feeder inlets 301, 302 are arranged to receive a plurality of objects and allow the objects to enter the inlet manifold 300. In other words, the one or more feeder inlets 301, 302 are adapted to convey objects into the inlet manifold 300.

[0047] In the depicted embodiment, the inlet manifold includes a first feeder inlet 301 and a second feeder inlet 302. Having multiple feeder inlets may allow for the simultaneous dispensing of different types of objects, as well as increasing the capacity of the inlet manifold.

[0048] In one embodiment, the first feed member inlet and the second feed member inlet may be adapted to receive objects within different size ranges or of different types, thereby achieving a more versatile device capable of receiving different types of objects without the need to replace parts. The different types of objects may refer to different types of grains, for example. Such adjustments for objects within different size ranges or of different types may include, but are not limited to, the geometry, depth, size and dimensions of the first feed member inlet and the second feed member inlet.

[0049] The inlet manifold 300 also includes at least two outlets 310 for distributing objects to the sorting units 100. As depicted, each of the at least two outlets 310 can be used to distribute objects to a separate sorting unit 100. However, it is contemplated that one outlet is connected to one or more sorting units, or that multiple outlets can be connected to one sorting unit.

[0050] The inlet manifold 300 further comprises a guiding device 350. The guiding device 350 connects the one or more feeder inlets 301, 302 and the at least two outlets 310. Thus, the guiding device 350 is arranged to convey objects between the one or more feeder inlets 301, 302 and the at least two outlets 310. The guiding device may also be adapted to distribute the objects into a portion between the at least two outlets 310.

[0051] The guiding device 350 is adapted to convey objects from one or more feeder inlets 301 , 302 to at least two outlets 310 downstream downwardly and diagonally relative to a horizontal reference plane.

[0052] Such an inlet manifold enables a compact system for sorting, which is still capable of sorting a relatively large number of objects, since the distribution of the objects between the sorting units takes place in the inlet manifold. Furthermore, the use of such an inlet manifold enables the transport of the objects in the same unit, which is preferred in terms of complexity and compactness.

[0053] The guide device 350 is adapted to transport the object downwardly and diagonally relative to a horizontal reference plane such that potential energy of the object transports the object along the guide device 350 .

[0054] Preferably, the guide device 350 is arranged to convey the object at an angle (e.g., an inclination angle) relative to a horizontal reference plane. The angle is greater than the object's angle of repose so that the object is conveyed at least partially by gravity. In one embodiment, the object is conveyed only by gravity conveying (e.g., only by the potential energy of the object).

[0055] However, it is conceivable to use the diagonal guidance provided by the guide device in combination with other conveying devices. In one embodiment, the inlet manifold can be provided with an oscillating drive system mounted to the guide device or the inlet manifold. The oscillating drive system can be configured to transmit a rocking motion to the guide device. The provision of the oscillating drive system enables the guide device to convey objects at a smaller inclination angle than a guide device that conveys objects only by means of gravity.

[0056] With reference to the above and further references to the angle of repose herein, it is generally noted that, although the objects to be conveyed in the apparatus 1000 and system may have different angles of repose, portions of the system may be arranged to convey the objects at angles outside of a reasonable angle of repose interval for the objects so that the objects are conveyed by gravity. The angle of repose herein generally refers to the angle between a horizontal reference plane and a diagonal direction facing upward and / or a plane extending diagonally upward. Thus, an angle greater than the angle of repose corresponds to a steeper downward facing direction, along which the object is conveyed, than the downward facing direction corresponding to the angle of repose. The angle greater than the angle of repose may be considered to be a downward angle relative to the horizontal component of the direction of motion of the object.

[0057] The guide device 350 can form a plurality of passages for conveying and distributing the objects to the at least two outlets 310. The plurality of passages can be formed as separate passages extending only between the feeder inlet and the outlet, or as open compartments provided with partition elements for guiding the objects to different desired locations (e.g., outlets), or a combination of both.

[0058] Reference Figure 3 , the first feeder inlet 301 is connected to one or more of the plurality of passages. The second feeder inlet 302 is correspondingly connected to one or more of the plurality of passages. For example, the first feeder inlet 301 is connected to the first passage 331. The first passage 331 is in turn connected to two outlets 310, whereby each outlet is suitable for being connected to or connected to the sorting unit 100. The second feeder inlet 302 is connected to the second passage 332, which has a guiding element for guiding part of the objects therein to the plurality of outlets 310 connected to the open passage 332. The passage can be formed by means of a flow separation wall section 309. Each outlet 310 is suitable for being connected to or connected to the sorting unit 100. In the depicted second passage 332, a flow separation wall section is provided at each outlet 310 for guiding a portion of the objects to the outlet 310. The flow separation wall section 309 extends substantially in the downstream direction of the object, i.e., in the conveying direction of the guiding device 350. The flow separation wall section 309 may be arranged close to the outlet 310 for guiding a fraction or a portion of the objects into said outlet 310 .

[0059] The guide device 350 may also include a diverter wall section 314. The diverter wall section 314 may extend substantially orthogonally to the downstream direction of the object. The diverter wall section 314 may be arranged downstream of each outlet 310 to prevent objects from passing over the outlet 310. In the depicted example, the diverter wall section 314 is connected to the corresponding flow separation wall section 309. The diverter wall section 314, the flow separation wall section 309 and the circumferential wall 315 of the guide device together partially extend around the outlet 310, thereby only allowing objects to enter the outlet 310 in the downstream direction.

[0060] In one embodiment, at least some or preferably all diverter wall segments can be pivoted around an axis substantially perpendicular to the direction of flow of objects in the inlet manifold. The axis can extend as a normal to the feed plane, which will be described in further detail later. The diverter wall segment can pivot around its axis so that the diverter wall segment is selectively arranged to cooperate with different flow separation wall segments, thereby controlling the extension of the guide device passage. For example, the diverter wall segment can pivot between a first position and a second position. In the first position, the diverter wall segment 314 can be arranged downstream of the outlet 310 to prevent objects from passing through the outlet 310. In the second position, the diverter wall segment 314 can be arranged to extend along the direction of flow of the object, and guide the object to pass through the outlet 310 to reach another outlet 310 arranged downstream of the outlet 310.

[0061] To enable easier delivery into the inlet manifold, the first and second feeder inlets 301, 302 may be disposed adjacent to each other at a feed section of the inlet manifold 300. Thus, at least two of the plurality of passages extend diagonally and downwardly from a position proximate to the feed section toward at least one outlet 310.

[0062] To achieve a more space-saving and simpler inlet manifold, the guide device 350 may include a guide plate member 320. The guide plate member 320 is arranged to convey the object. The guide plate member 320 may be adapted to convey the object downwardly and diagonally relative to a horizontal reference plane. The outlet 310 may be provided as a through hole in the guide plate member 320.

[0063] If you will refer to Figures 5 and 6 As further described, the guide device 350 may be arranged to convey objects along a feed plane. The feed plane is inclined relative to a reference horizontal plane. A guide device conveying objects along the same feed plane, for example via the guide plate member 320, can convey objects in a more space-saving manner by gravity (and potential energy) compared to having individual inclined conduits or channels.

[0064] Thus, the guide plate member 320 may be arranged to convey the object along the feed plane.The guide plate member 320 may extend along the feed plane.

[0065] A plurality of passages may be formed by the flow separation wall sections 309 provided on the guide plate member 320. Thus, a simpler inlet manifold is achieved.

[0066] Furthermore, the guide plate member 320 may be provided with a circumferential wall 315. The circumferential wall 315 may be provided on the guide plate member 320. The circumferential wall 315 is adapted to enclose the guide plate member 320. The diverter wall segment 314 may be connected and preferably pivotably connected to the circumferential wall 315. However, in an advantageous embodiment, the diverter wall segment 314 may be connected and preferably pivotably connected to the flow separation wall segment 309.

[0067] To illustrate the function of the inlet manifold 300, a plurality of objects can be fed into the inlet manifold via one or more feeder inlets 301, 302. The object stream is then separated by being guided along a guide device (e.g. a guide plate member 320) via different paths. This can be achieved by means of a flow separation wall segment. The separated parts of the object stream are then directed to an outlet 310 connected to the guide device and then introduced into the sorting unit 100 for subsequent sorting.

[0068] In the depicted embodiment, the guide device 350 comprises first and second sealing sections or passages connected to the first and second feeder inlets 301 , 302 respectively.

[0069] The first section or passage is connected to the first feeder inlet 301 and is defined by a portion of the circumferential wall 315 and a flow dividing wall segment 309. The first section or the first part of the passage includes a plurality of flow dividing wall segments 309 that can extend parallel to the downstream direction. An open path along the downstream direction is arranged between pairs of flow dividing wall segments 309, wherein each flow dividing wall segment 309 is adapted to guide a small portion of objects into a corresponding outlet 310. A diverter wall segment 314 is arranged at each outlet 310. The second part of the first section or passage is arranged downstream of the first part. At the second part, a portion of the circumferential wall 315 can form an angle relative to the downstream direction, thereby defining an open path, so that the flow of objects conveyed through the open path is separated between at least the first outlet and the second outlet 310 of the second part. The first outlet and the second outlet of the second part are arranged on opposite lateral sides of the open path. The first feeder inlet 301 can be arranged at the central axis of the guide plate member 320 extending along the downstream direction. Therefore, the open path can extend along the central axis.

[0070] The second section or passage is connected to the second feeder inlet 302 and is defined by a portion of a circumferential wall 315, a set of diverter wall sections 314 and a flow dividing wall section 309. The flow dividing wall section 315 forms an angle relative to the downstream direction so that the object flow from the second feeder inlet 302 is separated between at least the first outlet and the second outlet arranged downstream of the second feeder inlet. The first outlet and the second outlet of the second section are arranged on different lateral sides of the central axis. The second feeder inlet 302 can be arranged at the central axis of the guide plate member 320 extending in the downstream direction.

[0071] In the depicted embodiment, the diverter wall segment 314 may be movable to selectively direct objects conveyed in the first or second segment or passageway into its associated outlet 310. Thus, the diverter wall segment 310 may be movable to vary the extension of the first and second segments or passageways to thereby selectively include the outlet 310 in or exclude the outlet 310 from the first and second segments or passageways.

[0072] In order to enable maintenance and inspection, the inlet manifold 300 can be adapted to be releasably connected to the sorting unit 100. The outlet manifold 400 and the sorting unit 100 can be releasably connected by means of a releasable pipe connection. In order to achieve a sealed system, the releasable pipe connection can include a gasket. In one embodiment, the inlet manifold 300 and the sorting unit can be releasably interconnected by means of a support structure. Therefore, the support structure can include a connecting member, whereby the inlet manifold 300 (i.e., the outlet of the inlet manifold 300) and the sorting unit (i.e., the inlet of the sorting unit) are releasably connected to the connecting member. Therefore, the connecting member provides a passage for an object from the outlet of the inlet manifold to the inlet of the sorting unit.

[0073] As described above, the inlet manifold 300 may include a housing 340. The housing 340 is arranged to accommodate the guide plate member 320. The housing 340 is thus arranged to cover the guide plate member 320. The housing 340 may be provided with one or more through holes. The one or more through holes provide external access to the guide plate member 320, thereby forming the one or more feeder inlets 301, 302.

[0074] In one embodiment, the device 1000 may also include a door unit 390. In the depicted example, only one door unit is shown. The door unit 390 may be disposed at the inlet manifold 300. Each door unit 390 may be arranged in combination with the inlet manifold 300. Each door unit 390 is adapted to selectively enable the conveying and distribution of objects to the sorting unit 100. Therefore, the distribution of objects to the sorting unit may be adjusted according to the number and type of objects to be sorted and conveyed. For example, in the case of a large number of objects to be sorted, the door unit 390 may be opened so that each sorting unit receives a small portion of the total amount of objects. In some cases, only a relatively small amount of objects is to be sorted, in which case it may be disadvantageous to utilize all the sorting units. Therefore, one or more door units 390 may be closed during operation to enable the sorting unit to be removed without interrupting the sorting process. This may be particularly advantageous in the case where the sorting unit does not function properly or requires maintenance.

[0075] The door unit 390 may be arranged to selectively block the outlet 310. However, it should be noted that the door unit 390 may be located anywhere along the passage or relative to the entrance and still provide the same functionality.

[0076] In the depicted embodiment, the door unit 390 is a slidable door unit 390 that can slide between a first position and a second position. In the first position, objects are allowed to enter the sorting unit through the outlet 310. In the second position, the door unit 390 blocks objects from entering through the outlet 310. The slidable door unit can be operated manually and / or automatically. The slidable door unit can be slidably connected to the inlet manifold or a sorting unit in the plurality of sorting units described above.

[0077] Figure 4 Outlet manifold 400 is depicted in greater detail.

[0078] The outlet manifold 400 comprises a plurality of inlets 421, 422, 423 for conveying objects out of the sorting unit 100. The plurality of inlets 421, 422, 423 are thus adapted to be connected to said sorting unit 100. The plurality of inlets 421, 422, 423 and the outlet manifold 400 are arranged downstream of the sorting unit 100 and the inlet manifold 300 as a whole.

[0079] In order to enable maintenance and inspection, the outlet manifold 400 may be adapted to be releasably connected to the sorting unit 100. The outlet manifold 400 and the sorting unit 100 may be releasably connected by means of a releasable pipe connection. In order to achieve a sealed system, the releasable pipe connection may include a gasket. In one embodiment, the outlet manifold 400 and the sorting unit may be releasably interconnected by means of a support structure. Therefore, the support structure may include a connecting member whereby the outlet manifold 400 (i.e. the inlet of the outlet manifold 400) and the sorting unit (i.e. the outlet of the sorting unit (including the outlet of the sorting unit) are connected. Figure 7 The collector channel) described in further detail is releasably connected to the connecting member. The connecting member thus provides a passage for objects from the outlet of the sorting unit to the inlet of the outlet manifold.

[0080] In the depicted embodiment, the plurality of inlets 421, 422, 423 are adapted to be connected to a single sorting unit 100. Thus, the outlet manifold can collect the plurality of sorted fractions sorted in the sorting unit 100. Preferably, the plurality of inlets 421, 422, 423 of the outlet manifold 400 are connected to each sorting unit 100. The outlet manifold 400 is used to receive and convey the sorted objects O from at least two sorting units 100.

[0081] Advantageously, at least two inlets 421, 422, 423 of the plurality of inlets are adapted to be connected to each of the sorting cells 100 for conveying objects out of the sorting cells 100 after sorting in said sorting cells 100. A plurality of said inlets may extend parallel to each other.

[0082] The outlet manifold 400 may form one or more separate outlet passages 411, 412, 413. Each outlet passage 411, 412, 413 may be connected to a dispensing outlet 401, 402, 403 for conveying objects out of the object dispensing and conveying device 1000. For example, the dispensing outlet may be connected to a separate container for packaging objects or a separate machine for processing objects, etc.

[0083] The separated outlet passages 411, 412, 413 can be considered as separate, discrete or independent outlet passages. Therefore, each outlet passage can be separated from the remaining outlet passages. A plurality of said outlet passages can extend parallel to each other.

[0084] like Figure 4 As depicted, the inlets 421, 422, 423 connected to the first sorting unit 100 can each be connected to a corresponding separate outlet passage 411, 412, 413. In addition, the inlets 421, 422, 423 connected to the second sorting unit 100 can be connected to the same outlet passage 411, 412, 413, whereby the corresponding inlets connected to the first sorting unit and the second sorting unit can be combined by means of the same separate outlet passage. Therefore, a small portion of objects conveyed via the inlets 421, 422, 423 connected to the first sorting unit 100 can be conveyed out of the outlet manifold 400 through the same separate outlet passage 411, 412, 413 as the corresponding small portion of objects conveyed via the corresponding inlets 421, 422, 423 connected to the second sorting unit.

[0085] Thus, a first inlet 421 of the outlet manifold 400 connected to the first sorting unit 100 may be connected to the first separate outlet passage 411, and a second inlet connected to the first sorting unit 100 may be connected to the second separate outlet passage 412. Correspondingly, a first inlet 421 of the outlet manifold 400 connected to the second sorting unit 100 may be connected to the first separate outlet passage 411, i.e., the same first separate outlet passage 411, and a second inlet 422 connected to the second sorting unit may be connected to the second outlet passage 412, i.e., the same second outlet passage 412. This type of connection may be used for any number of inlets connected to a single sorting unit, any number of sorting units, and corresponding separate outlet passages.

[0086] Thus, the outlet manifold 400 comprises a plurality of inlets 421, 422, 423 for conveying the sorted objects out of the sorting units. The outlet manifold 400 further comprises at least two separate outlet passages 411, 412, 413. Each of the at least two separate outlet passages 411, 412, 413 is combined with at least two of the plurality of inlets 421, 422, 423. Each of the at least two inlets is arranged to convey the sorted objects from the respective sorting units 100 of the at least two sorting units 100 into the separate outlet passages. Thus, a first inlet of the at least two inlets may be adapted to be connected to a first sorting unit, a second inlet of the at least two inlets may be adapted to be connected to a second sorting unit, and so on.

[0087] The combined channels allow for a compact outlet arrangement of the system, thereby making the system more space-saving.

[0088] In other words, the outlet manifold 400 comprises a plurality of inlets 421, 422, 423 for conveying the sorted objects O from at least two sorting units 100. The first inlet 421 and the second inlet 422 are arranged to convey the sorted objects O from each sorting unit 100. The outlet manifold 400 comprises at least two separate outlet passages 411, 412, 413, whereby the first inlet 421 is combined with the first separate outlet passage and the second inlet 422 is combined with the second separate outlet passage. Each separate outlet passage 411, 412, 413 is connected to the distribution outlet 401, 402, 403 for conveying the objects out of the object distribution and conveying device.

[0089] like Figure 4 As depicted, a plurality of first inlets, each connected to a separate sorting unit 100, may be combined with a first separate outlet passage 411 for conveying a first small portion of sorted objects from the sorting unit 100. Similarly, a plurality of second inlets, each connected to a separate sorting unit 100, may be combined with a second separate outlet passage 412 for conveying a second small portion of sorted objects from the sorting unit 100.

[0090] Figure 5 and Figure 6 It is schematically depicted how the inlet and outlet manifolds may be arranged relative to the sorting units. In the depicted embodiment, the sorting units 100 are arranged adjacent to each other relative to a horizontal direction, or stacked on top of each other along a particular direction.

[0091] The inlet manifold 300 is arranged in an elevated position relative to the outlet manifold 400 so that objects are conveyed downward from the inlet manifold 300 to the outlet manifold 400. The inlet manifold 300 and the outlet manifold 400 may be connected via the sorting unit 100. Thus, the objects are conveyed from the inlet manifold 300 to the outlet manifold 400 via the sorting unit.

[0092] As mentioned above, the guiding device may be arranged to transport the objects along a feed plane FP.

[0093] The outlet manifold 400 can be arranged to convey objects at least partially by means of gravity and preferably entirely by means of gravity. Thus, the outlet manifold 400 can be adapted to convey objects from a plurality of inlets 421, 422, 423 downstream through at least two separate outlet passages 411, 412, 413 downwardly and diagonally relative to a horizontal reference plane. Thus, one or more separate outlet passages can be arranged to convey objects downwardly and diagonally downstream toward a distribution outlet. This can be achieved by means of the potential energy of the object. The one or more separate outlet passages and preferably the plurality of separate outlet passages 411, 412, 413 can each extend along an outlet feed plane OFP.

[0094] However, other conveying means can be envisioned to be utilized in conjunction with the diagonal guidance provided by the outlet manifold. In one embodiment, the outlet manifold can be provided with an oscillating drive system configured to rock the outlet manifold. The provision of the oscillating drive system enables the outlet manifold to convey objects at a smaller inclination angle than an outlet manifold that conveys objects solely by gravity.

[0095] The outlet feed planes OFP may each be arranged substantially parallel to the feed plane FP. The plurality of inlets of the outlet manifold 400 may form an inlet channel. The inlet channel of the outlet manifold may be adapted to convey objects downwardly and diagonally relative to a horizontal reference plane. As for the feed plane, the outlet passages and inlets of the outlet manifold may be arranged at an angle relative to the horizontal reference plane, the angle being greater than the angle of repose of the object, so that objects are conveyed at least partially by gravity in the outlet passages and inlets of the outlet manifold. In one embodiment, the inlet channel of the outlet manifold is arranged to extend substantially orthogonal to the outlet passages. In one embodiment, the inlet channel may extend substantially orthogonal to the outlet feed plane OFP.

[0096] like Figure 5 and Figure 6As shown, each sorting unit 100 may include a guide plate 10. Each guide plate has at least one channel extending in a sorting plane SP. The channel is inclined relative to a horizontal reference plane for conveying objects. The channel can be inclined so that the potential energy of the object conveys the object along the channel. Similar to the outlet manifold and the inlet manifold, it is conceivable that an oscillating drive or other device for conveying objects can be used as a supplement or alternative to the potential energy of the object for conveying the object.

[0097] In order to enable gravity to correctly transport the objects through the inlet manifold and the sorting unit, the angle formed between the feed plane FP and each sorting plane SP may be between 60 and 120 degrees. Preferably, the angle may be about 90 degrees.

[0098] Reference Figure 5 , at least one of the plurality of sorting units 100 is arranged above at least one other sorting unit 100 of the plurality of sorting units relative to the vertical reference direction. This type of stacked object sorting system does not require a large space and can be implemented by an object measuring and ejection system, which will be referenced to the object. Figure 7 The system is described in more detail. As mentioned above, a conventional camera-based sorting system would require too much space between each sorting unit, making such a stacked object sorting system unfeasible.

[0099] In one embodiment, at least two sorting units are arranged directly on top of each other relative to a vertical reference direction. In one embodiment, two or more sorting units are stacked on top of each other relative to said vertical reference direction. Two or more sorting units may be stacked on top of each other with a distance between each pair of adjacent sorting units.

[0100] In one embodiment, the angle between each sorting plane SP and the vertical reference direction is between 30 and 60 degrees. Therefore, the angle between the downstream direction of the object in the sorting plane SP and the vertical reference direction pointing downward may be between 30 and 60 degrees. Therefore, the angle between the downward facing normal direction of the sorting plane SP and the vertical reference direction may be between 30 and 60 degrees.

[0101] In one embodiment, at least two sorting units 100 may have channels extending in coincident sorting planes SP. Figure 6 , at least two sorting units 100 may have channels extending in substantially parallel sorting planes SP.

[0102] Preferably, the sorting units can be arranged in a matrix configuration, wherein more than one sorting unit 100 has overlapping sorting planes, and more than one sorting unit has substantially parallel sorting planes SP. Thus, any number of sorting units 100 can be arranged along a first direction, wherein the channels have parallel sorting planes SP, and any number of sorting units 100 can be arranged along a second direction, wherein the channels have overlapping sorting planes SP. Overlapping and / or parallel sorting planes SP enable a very compact object distribution and conveying system.

[0103] Further references Figure 6 In order to enable the conveying of objects by means of gravity and to achieve a compact system, at least two sorting units 100 may be distributed in a stacked configuration. Alternatively or additionally, sorting planes in which one or more channels of at least two sorting units 100 extend may be distributed in a stacked configuration. The sorting units 100 and / or the sorting planes SP may be arranged or distributed in a stacked configuration along a stacking axis SA. Preferably, the sorting units 100 and / or the sorting planes SP may be substantially uniformly distributed along the stacking axis SA.

[0104] In order to further increase the compactness of the system, the stacking axis SA may be arranged substantially parallel to the feed plane FP and / or the outlet feed plane OFP.

[0105] Advantageously, the sorting plane SP is arranged to extend at an angle relative to a horizontal reference plane, which angle is greater than the object repose angle, so that the objects are transported at least partly by means of gravity.

[0106] Thus, the outlet manifold 400, sorting unit 100, and inlet manifold 300 may together convey objects downstream and down through the system along a Z-path. The Z-path enables better utilization of the potential energy associated with the height of the system.

[0107] Now refer to Figures 7 to 10 The sorting unit 100 is described in more detail.

[0108] Figure 7 A top view of the sorting unit is shown in FIG.

[0109] The sorting unit 100 comprises a guide plate 10. The guide plate 10 has at least one channel 11. The at least one channel 11 extends in a sorting plane inclined relative to a horizontal reference plane for conveying the object O from a first longitudinal position P1 to a second longitudinal position P2. The second longitudinal position P2 is located downstream of the first longitudinal position P1. The first longitudinal position P1 is elevated relative to the second longitudinal position P2.

[0110] The sorting unit 100 further comprises a sorting inlet 71. The sorting inlet 71 is connected to one of the at least two outlets 310 of the inlet manifold 300 for conveying the objects O to the first longitudinal position P1.

[0111] The sorting unit 100 further comprises a sorting outlet 72 for conveying the objects O from the second longitudinal position P2 out of the sorting unit 100. The sorting outlet 72 may be provided at the second longitudinal position P2 for conveying the objects O out of the sorting unit 100.

[0112] Each sorting unit further comprises a sorting system, i.e. a separate sorting system configured to sort the objects conveyed through the sorting unit. The sorting system may be configured to sort the objects into two or more fractions. The fractions may be based on at least one measured characteristic of the object.

[0113] The sorting system comprises an object measurement unit 13 for performing a measurement associated with at least one characteristic of the object on the object O. The sorting system further comprises at least one ejector unit 14 arranged to eject the object O based on at least one measured characteristic of the object at a channel longitudinal position between the first longitudinal position P1 and the second longitudinal position P2.

[0114] The sorting system may further include a sorting system control unit 20. The sorting system control unit 20 may be operably connected to at least one ejector unit 14 and the object measuring unit 13. The sorting system control unit 20 may be configured to control the ejector unit 14 and the object measuring unit 13.

[0115] In one embodiment, the guide plate 10 has at least one channel 11 for conveying the object O between a first end 11 a and a second end 11 b of the corresponding channel 11 .

[0116] The guide plate 10 may be of metal, such as aluminium. The one or more channels may be formed by elongated recessed locations in the guide plate. The one or more channels may be formed by milling.

[0117] The guide plate may comprise a plurality of channels 11. The channels may extend parallel to each other along the guide plate 10. Preferably, the guide plate may comprise more than 30 channels, even more preferably more than 60 channels.

[0118] Advantageously, each of the plurality of channels may be provided with an object measurement unit and at least one ejector unit.

[0119] The object sorting capacity of the sorting unit 100 may be between 500 kg / h and 5000 kg / h. The objects may be, for example, grains, in which case the capacity of the sorting unit may be between 1500 kg / h and 3000 kg / h.

[0120] From the previously cited WO 2019 / 054932, a sorting system similar to the above-described sorting system is already known to those skilled in the art. Therefore, only a brief description of the sorting system and the sorting unit will be given below.

[0121] The at least one ejector unit 14 and the object measurement unit 13 may be operably connected to a control system. The control system may be configured to control the at least one ejector unit 14 and the object measurement unit 13. The control system may be operably connected to a sorting system control unit 20.

[0122] In one embodiment, the object measurement unit 13 is adapted to perform optical measurements associated with at least one characteristic of the object O. In one embodiment, the object measurement unit 13 comprises a light sensor device. The light sensor device may include a light emitter such as an LED and a light receiving unit such as a photodiode, the light receiving unit being used to receive light emitted from the light emitter after the light is irradiated to the object, thereby measuring at least one characteristic of the object. The light emitter may be configured to emit a near infrared (NIR) light beam onto the object. The light emitter may be arranged on an opposite side of the light receiving unit of the channel so as to face the light emitter.

[0123] In one embodiment, the optical measurement is performed by means of a camera system. Thus, the object measurement unit 13 may comprise one or more cameras configured to perform optical measurements associated with at least one characteristic of the object O. At least one camera may be arranged to perform said optical measurements on the objects conveyed through each channel of the sorting unit.

[0124] In one embodiment, optical measurements are performed via one or more measurement apertures 78 provided in the channel 11. The one or more measurement apertures 78 are provided between the first longitudinal position P1 and the second longitudinal position P2. The optical measurements are performed when the object O passes through the measurement aperture 78 towards the second longitudinal position P2.

[0125] In one embodiment, each of the at least one ejector unit 14 is arranged to eject the object O conveyed in the channel 11 when it reaches a ejection position downstream of the first longitudinal position P1 of the channel 11. Each ejector unit 14 may be associated with a respective ejection position, i.e. each ejector unit 14 may be arranged at a position along the channel 11 corresponding to the associated ejection position.

[0126] In one embodiment, at least one ejector unit 14 is a pneumatic ejector unit. The pneumatic ejector unit can be operated by means of a pneumatic system (e.g. Figure 1The pneumatic ejector unit is operated by a pneumatic system (as shown). Therefore, the pneumatic ejector unit is supplied with pressurized air from the pneumatic system to provide pressure for the ejection of the object. The pneumatic ejector unit is configured to release a concentrated pulse of pressurized air to eject the object. As described above, the concentrated pulse can be achieved by means of a valve controlled by a control system.

[0127] Advantageously, at least one ejector unit 14 is configured to eject the objects O based on at least one measured characteristic of the objects O and a timing signal associated with the conveying speed of the objects O along the channel 11. Compared to other prior art systems, this does not require camera equipment or the like for measuring the characteristics. Instead, this can be performed by determining the speed of the objects. This enables a more compact sorting system, since the space requirements for the object measuring unit are lower than, for example, camera equipment for directly measuring and determining the size and color of the objects.

[0128] In an alternative embodiment, the timing signal may instead be based on the type of object being conveyed. Thus, at least one ejector unit 14 may be configured to eject the object O based on at least one measured characteristic of the object O and a timing signal associated with a predetermined object type for the object O. Thus, a user may input the type of object to be conveyed and sorted, for example by means of a user interface of the system, whereby an appropriate timing signal may be automatically selected.

[0129] Reference Figure 7, an object measurement unit 13 is provided to perform an optical measurement associated with at least one characteristic of the object when the object passes through the measurement apertures 78 towards the second longitudinal position P2 via one or more measurement apertures 78. The measurement apertures 78 may optionally be provided with a grid, a grating or a transparent material (such as glass) which is adapted not to interfere with the optical measurement on the object O, so that the size of the apertures 78 does not have to be adjusted according to the size of the object, which in turn gives the opportunity to perform measurements in an axial plane over the entire length of the object O. Furthermore, the measurement apertures 78 may be arranged transversely to the plurality of channels 11 and optionally even interrupt the channel 11 at a certain detection gap (i.e. a gap extending over the entire channel 11). The measurement apertures 78 arranged transversely to the plurality of channels 11 may be combined with a grid or a grating. At least one ejector unit 14 is arranged to eject the object conveyed on the corresponding channel 11 when it reaches a corresponding ejection position located downstream of the measurement apertures 78, based on at least one measured characteristic of the object and a timing signal corresponding to the conveying speed of the object conveyed along the channel 11 (i.e. the associated speed of the object O moving towards its corresponding ejector unit 14). When more than one small portion is to be separated from a large number of objects, each channel 11 may be provided with more than one discharge position, each discharge position having a corresponding ejector unit 14 to separate the corresponding small portion based on at least one characteristic of the object O. In one embodiment, the measurement may be performed via a plurality of measuring apertures 78. Therefore, an optical sensor device may be arranged at each measuring aperture 78. Preferably, the measuring apertures 78 may be provided in the form of separate recesses provided in the channel 11.

[0130] Depending on the characteristics of the object, the object may not be discharged at any discharge position, whereby it is conveyed to the sorting outlet and conveyed out of the sorting unit.

[0131] In a less preferred embodiment, a separate collection tray, open channel, container or the like may be provided for collecting objects discharged from the channel and guide plate. However, such an embodiment is not preferred because there is a risk of contamination and objects missing the intended target.

[0132] exist Figure 8 as well as Figure 4 The preferred solution for collecting the discharged objects is best depicted in . According to the preferred solution, the sorting unit can be provided with a collector channel for collecting and conveying the discharged objects. The use of a sealed collector channel allows for a cleaner process, without the risk of dust and debris accumulating in other parts of the system or leaking into the system's surroundings.

[0133] Thus, the sorting unit 100 may comprise one or more collector channels. One or more collector channels may be arranged to collect the discharged objects for conveying the discharged objects out of the sorting unit 100. Thus, one or more collector channels may be arranged to receive the discharged objects and convey the discharged objects out of the sorting unit 100. One or more collector channels may be arranged to convey the discharged objects by means of gravity.

[0134] In one embodiment, the sorting unit 100 comprises a collector manifold 90. The sorting unit 100 may comprise a plurality of collector channels, whereby the collector manifold 90 comprises the plurality of collector channels.

[0135] A plurality of sorting units 100 may be connected to a plurality of inlets of the outlet manifold 400 for conveying objects to the outlet manifold 400. Thus, one or more collector channels and / or sorting outlets may be connected to at least one of the inlets 421, 422, 423 of the outlet manifold 400.

[0136] As further depicted, the sorting outlet may be connected to the outlet manifold 400 for conveying the objects out of the sorting unit 100. Thus, the sorting outlet may be connected to one of the inlets 421, 422, 423 of the outlet manifold 400.

[0137] In one embodiment, objects conveyed by means of the sorting outlet and the collector channel can both be conveyed to the outlet manifold. Thus, the sorting outlet and one or more collector channels of the sorting unit can be connected to different separate outlet passages 411, 412, 413 of the outlet manifold 400.

[0138] Therefore, the sorting outlet of the sorting unit 100 can be connected to the first inlet 421 of the outlet manifold 400. The collector channel of the sorting unit 100 can be connected to the second inlet 422 of the outlet manifold 400. Figure 4 As depicted, additional collector channels may be provided, whereby each of the additional collector channels may be connected to a corresponding inlet of outlet manifold 400 .

[0139] In an alternative embodiment, the objects can also be discharged at the second longitudinal position P2. Hence, one of the collector channels can form the sorting outlet 72. Hence, the second longitudinal position P2 can form the discharge position.

[0140] In one embodiment, the sorting outlet of the first sorting unit 100 and the sorting outlet of the second sorting unit 100 are each connected to the same first separate outlet passage 411 via the inlet of the outlet manifold 400 for conveying the sorted objects from the sorting outlet to the first separate outlet passage. Correspondingly, the first collector channel of the first sorting unit 100 and the first collector channel of the second sorting unit 100 can each be connected to the same second separate outlet passage 412 via the inlet of the outlet manifold 400 for conveying the sorted objects from the first collector channel to the second separate outlet passage. The second collector channel, the third collector channel, the fourth collector channel, etc. can be connected in a corresponding manner. In addition, the third sorting unit, the fourth sorting unit, the fifth sorting unit, etc. can be connected to the same separate outlet passage in a manner corresponding to the first sorting unit and the second sorting unit.

[0141] Although not depicted, the system may be provided with a built-in bypass to avoid blockages. The built-in bypass may be in the form of a bypass passage that directly connects the inlet manifold and the outlet manifold without conveying the objects through the sorting unit. The bypass passage may connect one or more inlets of the inlet manifold with one or more outlets of the outlet manifold for conveying the objects from the inlet manifold to the outlet manifold. The bypass passage may be selectively closed, for example, by means of a gate unit. The built-in bypass enables conveying a small portion of unsorted objects from the inlet manifold directly to the outlet manifold, thereby achieving a greater flow of objects in the overall system without the need for additional sorting units.

[0142] Preferably, the object distribution and conveying system is a closed system, whereby the connection between the inlet manifold, the outlet manifold and the sorting unit is a sealed connection. In one embodiment, the system may comprise a suction system configured to generate a negative pressure in the direction of the outlet manifold. The suction system may comprise a fan system, such as an aspirating system for causing dust to leave the system. In one embodiment, an exhaust unit may be arranged in the outlet manifold together with an air channel for causing dust to leave the outlet passage.

[0143] Reference Fig. 9, the system may include a plurality of feed rollers 82. Each feed roller 82 may be arranged at the sorting entrance 71 of a sorting unit 100 in a plurality of sorting units for controlling the distribution of objects into the sorting unit 100. Therefore, the feed roller 82 may be configured to control the distribution of objects into the sorting unit 100. The feed roller 82 may be operably connected to a control system, whereby the control system is configured to control and adjust the speed of the feed roller 82. The feed roller extends to the entire sorting unit 100, preferably to the entire width of the sorting entrance 71, i.e., to the entire cross-section of the sorting entrance 71. Therefore, the feed roller enables the distribution of objects over the entire width of the sorting entrance 71. The feed roller may be provided with a guide member that pushes the object to move when the roller rotates. In one embodiment, the feed roller 82 is arranged at each sorting entrance 71.

[0144] Preferably, during operation, the guide means is close to being completely filled with objects, whereby the feed rollers 82 gradually feed the objects into the channel of the sorting unit.

[0145] In the depicted embodiment, the sorting inlet 71 includes a buffer zone. A feed roller 82 may be arranged downstream of the buffer zone in the sorting inlet 71 to distribute the objects into the sorting inlet 71 of the sorting unit 100.

[0146] Further references Fig. 9 , the sorting unit 100 may be provided with an inspection device 86 for visually controlling the interior of the sorting unit 100. The inspection device 86 may include an inspection hole and a cover 85 for selectively closing the inspection hole. It is also conceivable that the sorting unit is provided with a transparent part, thereby allowing a user to inspect its interior. Preferably, the inspection device 86 may be arranged to selectively enable visual control of the interior of the buffer zone of the sorting unit 100.

[0147] Fig.10 Other aspects of the system are depicted.

[0148] For example, in order to facilitate maintenance and replacement of the sorting unit 100, the support structure can be adapted to movably receive the sorting unit 100. The object and conveying device can therefore further include an attachment device to releasably fix the sorting unit 100 to the support structure. The attachment device can be adapted to selectively enable relative movement between the support structure and one or more sorting units 100. In one embodiment, the support structure may include a track 599 adapted to accommodate the sliding movement of the sorting unit 100 relative to the support structure. The track 599 can be permanently mounted to the support structure, or releasably mounted to the support structure.

[0149] like Fig.10As further depicted, the sorting unit 100 may include an electronic module 97. The electronic module 97 may house one or more ejector units and an object measurement unit of the sorting system. The electronic module 97 may further house valves, pneumatic circuits, printed circuit boards, etc. that operate the ejector units and object measurement units of the sorting system. The electronic module 97 may be disposed on an outer surface of the sorting unit 100, i.e., form a part thereof, so that the operator can easily access it. In addition, the electronic module 97 may be arranged to be accessible when the sorting unit 100 is released from the support structure. In the depicted embodiment, the electronic module includes two separate submodules, however, it is conceivable that the electronic module may include any number of submodules. In one embodiment, the electronic module is disposed in a single housing.

[0150] According to one aspect, an object sorting system is provided. The object sorting system may include a reference Figures 1 to 10 An object sorting system with multiple sorting units is described.

[0151] The object sorting system may include a plurality of sorting units 100. The plurality of sorting units 100 include a guide plate 10. The guide plate 10 has at least one channel 11. The at least one channel 11 extends in a sorting plane SP inclined relative to a horizontal reference plane for conveying an object O from a first longitudinal position P1 to a second longitudinal position P2 downstream of the first longitudinal position P1. The first longitudinal position P1 is elevated relative to the second longitudinal position P2.

[0152] The object sorting system further comprises a sorting inlet 71 and a sorting outlet 72 . The sorting inlet 71 is used to transport the object O into the sorting unit 100 to reach the first longitudinal position P1 , and the sorting outlet 72 is used to transport the object O out of the sorting unit 100 from the second longitudinal position P2 .

[0153] The object sorting system further comprises a sorting system comprising an object measurement unit 13 for performing measurements on the object O associated with at least one characteristic of the object O and at least one ejector unit 14. The at least one ejector unit 14 is arranged to eject the conveyed object O based on at least one measured characteristic of the object at a longitudinal position of the channel 11 between the first longitudinal position P1 and the second longitudinal position P2.

[0154] At least one sorting cell 100 of the plurality of sorting cells is arranged above at least one other sorting cell 100 of the plurality of sorting cells with respect to the vertical reference direction.

[0155] Each of the plurality of sorting units includes a sorting system.

[0156] In one embodiment, the angle between each sorting plane SP and the vertical reference direction is between 30 degrees and 60 degrees.

[0157] In one embodiment, at least two sorting units 100 have channels 11 extending in coinciding sorting planes SP.

[0158] In one embodiment, at least two sorting units 100 have channels 11 extending in substantially parallel sorting planes SP.
