Description
Device for processing a batch of objects
TECHNICAL FIELD
The invention relates to a device for processing a batch of 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.
BACKGROUND A sorting device for sorting a batch of small, lightweight objects is known from WO2011115482A1. The seed sorting device is configured to inspect each individual seed from a batch of seed and to remove seed with characteristics not complying with 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 endless 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. Furthermore, a pocket has a round, oval or elliptic shape such that after the pockets are filled with seed, and 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.
In the known sorting device, the trays are coupled to the endless chain and go around with a speed and pass 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. In the tray filling part, a continuous flow of seed is falling on each tray. In 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. In this part by means of a camera one or more images will be 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 are: 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. If a seed in a particular pocket has at least the minimal desired quality, in the selective seed removal part, 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 airflow 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. Finally, 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 sorting capacity of the known device is limited by the number of pockets in a tray and the speed of a tray. The optimal sorting capacity is obtained when the size of the pocket corresponds to the size of the objects to be sorted. Thus when two batches with differing size of objects have to be sorted, the trays have to be replaced to have the optimal sorting capacity. Furthermore, the removal of the seed surplus from the tray in the seed surplus removing part could damage the objects. WO2012067512A2 discloses a similar sorting system. In this document an embodiment is described wherein the endless chain of trays is replaced by an endless conveyor belt. In the filling section the objects are scattered on the endless conveyer belt. A sorter for reclaiming particles, such as glass particles, is known from US3980180. The sorter utilizes a belt conveyer having a longitudinal row of dimples formed in the upper surface and around an opening. Particles are positioned in the dimples over the openings and pass a light source and sensor on opposite sides of the belt to sense the transmissivity, or colour of the particles. Glass particles having a predetermined transmissivity are separated by an air jet directed through the openings in the belt. The sorter comprises a complex feeding station to guide particles into seats of a belt conveyer. Gravity biased rakes arrange the particles into longitudinal rows or guide the particles into seats on the belt conveyer. From this belt conveyer the rows of particles in the seats are dropped in the dimples over the openings of the belt conveyer. The conveyer with seats and the conveyer with dimples are timed to deposit the particles into the dimples directly over the apertures in the belt conveyer. A disadvantage of rakes is that oversized particles have to be eliminated prior to supplying the particles to the gravity biased rakes. An oversized particle will stuck in the passage between two adjacent teeth and consequently block the passage of other particles.
SUMMARY
It is an object of the invention to provide an improved device for processing a batch of objects which overcomes at least one of the problems described above.
According to the invention, this object is achieved by a processing device having the features of Claim 1. Advantageous embodiments and further ways of carrying out the invention may be attained by the measures mentioned in the dependent claims.
According to a first aspect of the invention, there is provided a device for processing a batch of objects. The device comprises at least a filling unit and a transportation unit. The transportation unit comprises an object carrier having a top surface suitable for carrying the objects. The filling unit is configured for dropping objects on the top surface of the object carrier. The filling unit comprises a container for receiving the batch of object and a singulating section. The singulating section is configured to divide a stream of randomly supplied objects from the container in two or more rows of objects to be dropped on the object carrier. The singulating section is in the form of an inertial-type conveyor unit. The inertial-type conveyor unit comprises a first transport section and a second transport section downstream the first transport section. The first transport section is configured for transporting the stream of randomly supplied objects from the container to the second transport section. The second transport section comprises N grooves (108B1) and N-1 ridges (108B2) between the N grooves. The N-1 ridges are configured to divide the stream of randomly supplied objects over the N grooves in N sub-streams. The N grooves are configured for transporting objects of the N sub-streams to the transportation unit (102). N is an integer greater than 1. In a particular embodiment, the second transport section comprises two grooves and a ridge between the two grooves. The ridge is configured to divide the stream of randomly supplied objects over the two grooves in two sub-streams. The two grooves are configured for transporting objects of the two sub-streams to the transportation unit.
The device according to the invention has the advantage that the singulating unit does not comprise obstacles for too large objects in the batch. Therefore, there is no need to sieve the batch to eliminate objects which have sizes not within a selected range of sizes. Furthermore, as there are no obstacles in the singulating unit as a result of which objects could be blocked during transportation on the singulating unit, the risk that an object is damaged by friction is reduced significantly. A further improvement is that the singulating unit allows dropping the objects in rows on the top surface of the transportation unit as a result of which each object could be examined individually and sorted. There is no need to have a transportation unit with pockets. As a consequence, a particular object carrier is suitable for a greater range of products. This requires fewer types of object carriers to sort all types of products. Furthermore, there is no need to remove a surplus of objects from the object carrier. An object is dropped only once on the object carrier before it is examined in the inspection part of the processing device. This reduces the possibility of damaging the object. An advantage of an inertial-type of conveyor is that it allows gentle handling and transportation of fragile objects with minimum degradation.
In an embodiment, the first transport section has a top surface with a downstream end which forms the transition from the first transport section to the second transport section. The downstream end has in transport direction of the objects a level which is not lower than the top surface of the second section at the location of the transition from the first transport section to the second transport section.
These features provide a simple to manufacture structure wherein gravity ensures that the ridge divides the stream of objects on the first transport section in two sub-streams on the second transport section.
In an embodiment, the first transport section is configured to supply the stream of randomly supplied objects to the second transport section in a manner that the ridge divides the stream of randomly supplied objects in essentially two equivalent sub-streams.
This feature enables to divide the sub-streams of objects in smaller sub-streams wherein each of the smaller sub-streams comprises a similar amount of objects.
In an embodiment, the singulating section further comprises a third transport section downstream the second transport section. The third section comprises four grooves. The four grooves form two pairs of two grooves. A ridge between the two grooves of a pair of two grooves is configured to divide a substream of objects over the two grooves of a pair in two sub-sub-streams of objects. The two grooves being configured for transporting objects of the two sub-streams to the transportation unit. This feature enables to increase the processing capacity of the processing device by increasing the number of rows of objects on the object carrier that could be processed simultaneously.
In a further embodiment, the grooves of second transport section have a downstream end which forms the transition from the second transport section to the third transport section. The downstream end has in transport direction of the objects a level which is not lower than the top surface of the third section at the location of the transition from the second transport section to the third transport section. This feature ensures that the objects in a groove of the second transport section will be transferred to a groove of the third transport section by their own weight by falling from the downstream end of a groove of the second transport section via a ridge in a groove of the third transport section.
In a further embodiment, a ridge of the third transport section is at the transition from the second to the third transport section located below the middle of the downstream end of a groove of the second transport section. This feature enables to divide the stream of objects in a groove of the second transport section in two essentially equivalent streams of objects in two grooves of the third transport section.
In an embodiment, the singulating section further comprises a final transport section. The final transport section comprises alternately a groove portion and an intermediate portion. A groove portion is configured to receive objects from an upstream transport section. The groove is further configured to drop the received objects at the downstream end of the groove on an object carrier of the transportation unit. In transport direction the intermediate portions extend further than the groove portions. These features enable to drop individual objects on the top surface of the object carrier. When an object is dropped on the object carrier it is transported over a predefined distance between the intermediate portions. The intermediate portions ensure that after an object is dropped on the object carrier, the object could not move during acceleration to the speed of the object carrier in a direction perpendicular to the transport direction of the object carrier. In this way, parallel rows of objects could be formed on the object carrier even if the surface of the object carrier is flat.
In a further embodiment, the device comprises a first vibration generator and a second vibration generator, the first vibration generator is configured to subject the first transport section to a first vibration and the second vibration generator is configured to subject the final transport section to a second vibration, the first vibration and the second vibration having different characteristics. This feature allows moving forward the object with different speed.
In this way, the possibility that two objects are dropped simultaneously from a groove on the object carrier is reduced significantly.
In an embodiment, the object carrier is an end-less belt, the top surface of the end-less belt comprises longitudinal grooves. The grooves ensure that the objects will be aligned in parallel rows on the object carrier.
In an embodiment, the object carrier is a tray-type carrier; the top surface of the object carrier comprises a multitude of elongated pockets. The elongated pockets are parallel. Each elongated pocket comprises an elongated bottom with an elongated hole (904) through the object carrier. This feature makes it possible to use the invention in a sorting device as described in WO2011115481A1 and WO2011115482A1.
In a further embodiment, the elongated bottom and the elongated hole have similar length. This feature allows reducing the distance between objects in transport direction. This increases the processing capacity of the device.
Other features and advantages will become apparent from the following detailed description, taken in conjunction with the accompanying drawings which illustrate, by way of example, various features of embodiments.

DETAILED DESCRIPTION
The processing device according to the present application will be described with reference to the Figs 1-5. Fig. 1 shows a perspective view of the processing device 100 for processing a batch of objects. Fig. 2 shows an enlarged view of a detail of Fig. 1 which is indicated in Fig. 1 by circle indicated with reference II. Figs 3 - 5 show respectively a top view, a side view and a front view of the processing device. The device comprises a transportation unit 102, and a filling unit 104. A processing device for sorting a batch of object further comprises an inspection unit and an object removal unit. These units have not been shown as they are regarded not to be essential for applying the concept of the present invention and are thus not described in further detail. The present application is designed for processing different type of small, lightweight objects such as seeds. Some examples of seeds are paprika seed, pepper seed, cucumber seed, tomato seed, gherkin seed, melon seed and beans. The present application is also suitable for processing other types of objects, for example coloured glass particles.
The transportation unit 102 in the embodiment shown in Fig. 1 comprises an object carrier 102A in the form of a flat belt conveyor, end-less belt, or a conveyor belt. The transportation unit 102 further comprises a number of pulleys 102B. The object carrier 102A comprises a top surface 102A1 suitable for carrying the objects. The top surface 102A1 comprises a number of parallel longitudinal grooves 102A2. The transport direction of the conveyor belt 102A is indicated in Figs. 3 and 4 by arrow 300.
The grooves 102A2 are parallel to the moving direction of the conveyor belt. The grooves 102A2 ensure that objects with a circular cross section will almost not move in a direction perpendicular to the moving direction of the belt when dropped and positioned in a groove. As a result, a number of parallel rows can be transported and processed by the processing device. The inspection and removal of objects in parallel rows is less difficult than objects which are randomly positioned on the object carrier. It might be clear that the grooves are not needed in case the objects have one or more substantially flat sides.
The filling unit 104 is configured for dropping the objects on the top surface of the object carrier. The filling unit 104 comprises a container 106 and a singulating section 108. The singulating section is configured to divide a stream of randomly supplied objects from the container in two or more rows/streams of objects and to drop the objects from the respective rows/streams on the object carrier 102A. In this way, parallel rows of objects are formed on the object carrier for further processing.
The singulating section 108 is in the form of an inertial-type conveyor unit. Inertial-type conveyors are also known as vibration conveyors and oscillating conveyors. An inertial-type conveyor system moves articles from one position to another by moving back and forward the transport surface on which the articles are positioned. During a forward stroke of the transport surface, the transport surface moves at a first acceleration whereby the frictional contact between the articles and the transport surface moves the articles in the same direction as the transport surface. Then during a return stroke, which is of an equal distance, the transport surface moves at a second acceleration generally greater than the first acceleration such that the articles continue to move by inertia on the transport surface while the tray is moving backward.
The inertial-type conveyor unit 108 according to the present embodiment comprises a first transport section 108A, a second transport section 108B downstream the first transport section, third transport section 108C downstream the second transport section and a final transport section 108D downstream the third transport section. The terms “upstream” and “downstream” relate to an arrangement of items or features relative to the transportation direction of objects through the system.
The filling unit 104 which could also be named as feeder functions as follows. A batch of objects is inserted in the cavity of the container 106. The objects leave the container via an opening at the bottom side of the container in a stream of randomly supplied objects. Fig. 1 shows a slider 106A to control the amount of objects or the flow of objects leaving the container. The first transport section 108A transports the stream of randomly supplied objects to its downstream end. When the objects pass the downstream end of the first transport section, the objects fall in two grooves 108B1 of the second transport section 108B. A ridge 108B2 between the two grooves 108B1 divides the stream of randomly supplied objects over the two grooves in two sub-streams. The second transport section transports the objects in the two grooves as two sub-streams to downstream ends of the second transport section. When the objects pass the downstream end of the second transport section, the objects from one groove of the second transport section fall in a pair of two grooves 108C1 of the third transport section 108C. A ridge 108C2 between the two grooves 108C1 of a pair divides the stream of objects from one groove of the second transport section over the two grooves of a pair. In this way, the stream of randomly supplied objects coming out of the container is distributed over grooves to obtain four streams of objects. The third transport section transports the objects in the four grooves as four sub-sub-streams to downstream ends of the third transport section. When the objects pass the downstream end of the third transport section, the objects from a groove of the third transport section fall in a smaller corresponding groove 108D1 of the final transport section 108D. The final transport section 108D transports the objects to the downstream end of the grooves and drops subsequently the objects in a corresponding groove 102A2 in the surface 102A1 of the object carrier 102A. In this way, rows of objects are formed on the surface of the object carrier wherein the objects are in a row one after another and generally at some distance from each other in transport direction.
The embodiment shown in Fig. 1 and Fig. 2 comprises a first vibration generator 110A and a second vibration generator 11 OB. The first vibration generator is configured to subject the first, second and third transport section to a first vibration. The second vibration generator is configured to subject the final transport section to a second vibration, the first vibration and the second vibration having different characteristics. In this way, the transport velocity of the objects on the final transport section could be made higher than the transport velocity of the objects on the first, second and third transport section. As a result of this a distance could be created between subsequent objects on the final transport section. This allows that if two objects fall simultaneously from one groove of the third transport section in a corresponding groove of the final transport section, the objects could be positioned one after the other in a groove of the final transport section. As a consequence, at the downstream end of a groove of the final section each time only one object is dropped on the surface of the object carrier 102A1.
It should be noted that only one vibration generator is necessary if the stream of objects in the grooves of the transport section upstream the final transport section are already positioned one after another. It should further be noted that each transport section might have its own vibration generator.
Fig. 6 shows a top view of the singulating section 108 and Fig. 7 shows a front view of the singulating section 108. From these figures can be seen that ridge 108B2 of the second transport section 108B is positioned below the centre axis of the transport surface of the first transport section 108A. When approximately half of the objects of the randomly supplied stream of objects is transported at the left from the centre axis and the other half of the objects is transported at the right from the centre axis, the ridge 108B2 realizes that the randomly supplied stream is divided in two sub-streams of object with a comparable flow of objects. In other words, the first transport section 108A has a top surface with a downstream end which forms the transition from the first transport section 108A to the second transport section 108B. The downstream end has in transport direction of the objects a level which is not lower than the top surface of the second section at the location of the transition from the first transport section to the second transport section. The first transport section is configured to supply the stream of randomly supplied objects to the second transport section in a manner that the ridge divides the stream of randomly supplied objects in essentially two equivalent sub-streams of objects.
In a similar way, the ridges 108C2 of the third transport section 108C are positioned below the centre axis of the grooves 108B1 of the second transport section 108B and divide a stream from a groove 108B1 of the second transport section 108B in two smaller streams with essentially the same flow of objects. In other words, a ridge 108C2 between the two grooves of a pair of two grooves of the third transport section 108C is configured to divide a sub-stream of objects over the two grooves of a pair in two sub-sub-streams of objects. The four grooves of the third transport section are configured for transporting objects of the two sub-sub-streams forward to the transportation unit 102. Furthermore, the grooves 108B1 of second transport section 108B have a downstream end which forms the transition from the second transport section to the third transport section 108C, the downstream end has in transport direction of the objects a level which is not lower than the top surface of the third section at the location of the transition from the second transport section to the third transport section. A ridge 108C2 of the third transport section 108C is at the transition from the second to the third transport section located below the middle of a downstream end of a groove 108B1 of the second transport section 108B. As a result of this, no objects will be blocked at the transition as there are no obstacles when moving from one transport section to a subsequent transport section. Even when objects are present which are larger than the width of a groove, these larger objects will always be moved in the direction of the object carrier and finally dropped on the object carrier.
Figs 6 and 7 further discloses further clearly the structure of the final transport section 108D. The final transport section comprises alternately a groove portion 108D1 and an intermediate portion 108D2. A groove portion 108D1 is configured to receive objects from an upstream transport section and configured to drop the received objects at the downstream end of the groove 108D1 on the object carrier, not shown in Figs 6 and 7. It can be seen in Fig. 6 that in transport direction of the objects the intermediate portions extend further than the groove portions.
In an alternative embodiment, the third transport section 108C and the final transport section 108D are combined in to one transport section. In this embodiment, the width of the groove is gradually reduced. And the shape of the groove in transport direction gradually changes from semi-circular to a V-shape or U-shape. In the latter case, the ridge gradually flattens in transport direction to become an intermediate portion.
It should further be noted that in the event the objects from the container are evenly distributed along the entire width of the surface of first transport section, the second transport section could comprise three or more grooves and corresponding ridges between the three or more grooves. In this case, the randomly supplied stream of objects is divided into three or more substream when moving from the first transport section to the second transport section. The objects could be evenly distributed along the entire width of the first transport section if the surface is horizontally and essentially flat.
Fig. 8 illustrates a front view of a second embodiment of a singulating section. This embodiment shows that the concept of singulating can easily be used to generate eight rows of objects on the object carrier. In this embodiment, the cross section of the first transportation section 108A is V-shaped and not U-shaped as in the first embodiment. Furthermore, the ridge 108B2 of the second transport section has a rounded top and not a sharp top. It might further be clear that the cross section of a groove of a transport section is not limited to semicircular.
It is commonly known that a vibration conveyor with a flat surface in transport direction could convey most materials at a 5° incline from horizontal line. The concept of the present application is therefore not limited to grooves that are orientated horizontally in transport direction.
The filling unit described above could also be used to feed trays that could be used in a sorting device as described in WO2011115481A1 and WO2011115482A1. Fig. 9 shows a top view of an embodiment of a tray-type object carrier 900. The top surface of the object carrier comprises a multitude of elongated pockets 902. The elongated pockets are parallel to the transport direction 909 when passing the filling unit. In each elongated pocket a row of objects could be positioned. Traverse the transport direction, the object carrier 900 comprises 32 parallel elongated pockets. Each elongated pocket comprises an elongated bottom with an elongated hole 904 through the object carrier. The elongated bottom and the elongated hole have similar length. By means of a blow unit, objects could be selectively removed from the elongated pocket. Due to the small distance between two adjacent rows and material constraints, the elongated holes have a limited length. By maintaining some material 906 between ends of elongated holes in transport direction, structure between adjacent grooves could be strong enough to carry the objects and to limit the deformation of the structure in lateral direction. In Fig. 9 the construction of material 906 between the elongated holes divides the elongated pocket 902 in four smaller elongated pockets.
Fig. 10 shows a sectional view of the object carrier shown in Fig. 9 along line X - X and Fig. 11 shows an enlarged view of a part of Fig. 10.
