Definitions
- the invention relates to a device for a feature-related sorting of products, in particular small-scale agricultural products, products from the food industry or other sequential mass flows, and to a method for operating the device.
- US Pat. No. 5,388,705 describes a device in which plastic bottles are classified as contaminated by a detection station or in some other way as defective by means of an ejector (plunger) operated with compressed air.
- a prerequisite for this solution is a strict lateral alignment of the plastic bottles of uniform standard size between the detection station and the ejector.
- This solution uses four reflective barriers, which are directed to the height of the bottle necks arriving serially on a belt, which only serve as position indicators and only provide a yes / no signal.
- This teaching is not suitable for achieving the object of the present invention.
- DE 195 32 306 AI also describes a sorting device for bottles, in which a stepper motor drives a cam disc-shaped sorting device which impulses the bottles to be sorted out with an impulse-like impact.
- a prerequisite for the functionality of this device is the strict alignment of the bottle flow to be sorted, with all bottles having to be in the same position with respect to a constant small distance from the rejecting device.
- a product-friendly sorting out according to different characteristics from a product stream with different sizes and quality is also not possible with this solution.
- the closest known devices to the invention are sorting devices in the fields of agriculture and Food industry. From DE 27 23 674 AI a device is known in which a discharge plate is provided in a falling stream to be sorted crop, which is actuated by a previous detection device and can carry out a sorting in two fractions.
- a similar sorting into two fraction streams is described in DE 27 09905 AI, in which stones in particular are to be separated from harvested material and in which a finger unit adjustable in two positions, for example, clears a way for the vertical diarrhea of stones.
- a further improvement is brought about by an optoelectronic sorting machine, as described, for example, in DE 41 27 903.
- the principle of these selectors is that the products to be read out are optoelectronically scanned individually, one after the other in a drop space by, for example, image converters arranged at 120 ° to one another. Products with damaged areas are identified and an incorrectly identified product is separated from the material flow by means of an air blast using suitable computer programs.
- sorting machines work for example with potatoes with throughput rates of up to 5000 kg / h.
- quality selection or size sorting of smaller or more sensitive products such as tomatoes, beans, peas, stone fruit, pome fruit, berries, carrots, finger tubes, carrots, onions, cereal grains, legumes, almonds, nuts, spice grains etc. or also, for example, French fries
- these machines are not suitable in view of the throughputs required there or the sensitivity of the products.
- the quality sorting of small-sized products is carried out according to the current state of the art in such a way that the products are placed on a conveyor belt at a distance from one another, detected there by optoelectronic image converters and at the end of the belt by appropriately controlled selection mechanisms defective products are separated from the crop flow.
- the disadvantages of this approach are manifold. In this way, the products can overlap on the conveyor belt, so that damaged ones cannot be recognized at all. As a result of unsteady conveyor belts, defective products can be detected until they are ejected when they are recognized Experience changes in position so that they get into a different path and are therefore not discarded.
- the invention has for its object to provide a device for a feature-related sorting of any lumpy products and a method for their operation, the very sniff, at least triple-eyed fractionation of a product stream with gentle product handling, low energy consumption, low noise emissions and high wear resistance
- a largely automatic adjustment to the target result of the sorting is possible.
- product parameters such as volume, speed, part contour, center of mass, damage control, deflection characteristic, angular momentum or the like should be included. be understood.
- the essence of the invention is that products of a sequential partial product flow pass through a first approach zone, into a second zone, in which a separating element which can be rotated by means of a stepping motor is provided, which carries circumferentially equally spaced fingers and which, depending on the control, the products to be sorted in at least three more Sub-fraction flow zones transferred, wherein a real-time image tracking system is provided such that it allows the entire path of the products to be recorded through the three zones mentioned and assigned to each individual product and addressable individual product information, such as one or more parameters such as volume, speed, part contour, center of mass , Damage control, deflection characteristics, angular momentum or the like, is stored in a memory, the addresses or address ranges of which are permanently assigned to the geometric coordinates of the zones traversed by the products and to the geometric coordinates of the starting position or congruent control of the separating element with a resolution of the order of magnitude of 1 mm / address and whose access speed is at least so great that between each image stored by the image
- the operation of the device takes place essentially in such a way that a real-time image tracking system detects each product part of the sequential partial product stream starting from the entry into the first approach zone, via a second zone which can be detected by the separating element to the third partial fraction flow zone, each product from the entry in the proximity zone is continuously recorded in a memory, the signals generated by processors and suitable programs are fed to the stepper motor in such a way that when a product part to be selected enters the second zone it drives the separating element such that a finger of the separating element is on the product part is accelerated towards The moment of product transfer is briefly braked and then immediately subjected to a defined acceleration related to the product part and placed in such a final control that the fingers of the separating element are moved to a control unit that is congruent to their starting position after product part selection has been made, regardless of the experienced direction of rotation.
- Fig. 1 shows a training possibility of the invention
- Fig. 2 is a possible training one used
- FIG. 3 a a longitudinal section through a finger of a separating element according to FIG. 2 and FIG. 3 b a section along a plane X-X through a finger according to FIG. 3 a.
- the device according to the invention with its features essential to the invention is shown schematically in its entirety.
- the products in a channel k which has only been indicated, have already been lined up one behind the other and leave this path p, here a flight parabola, as a sequential partial stream or are forwarded in such a stream.
- the products 51, 52, 53 shown here pass through a first zone a, referred to as the approach zone, followed by a zone b, in which a separating element 1 is provided, and, depending on the selection to be made, reach partial fraction streams cl, c2 and c3.
- further fraction control streams can be provided.
- Deflection characteristics are each addressed in a separate microprocessor 40 and fed from there to a main coordinate processor 4. Signals outgoing from the main coordinate processor 4 are fed to a high-speed stepping motor 2. This carries a separating element 1, which is discussed in more detail in the context of the description of the figures for FIGS. 2, 3 a and 3 b.
- the individual product parameters which have already been detected in a feature-related manner until the separation zone b has been reached by the real-time exposure detection system 3 are available for actuating the stepping motor 2 and, in the example in FIG remains in the passage at rest position, follows the path cl, whereas in the example a cargo 52 that is too small gets into the path c2 and a rotten fruit 53 gets into the path c3 due to the influence of the separating element 1.
- the structure which is most advantageous within the scope of the invention should first be carried out.
- Figure 2 shows a separating element 1 in plan view.
- Fingers 10 are arranged in a star shape, circumferentially uniformly distributed around an unspecified central part, in the example in each case by an angular offset of 72 °.
- a higher number of fingers can also be provided, but at least three fingers 10 in the sense of the invention.
- the fingers are also preferably provided with a covering 11 consisting of a very soft elastomer.
- the fingers are as in 3 a and 3 b indicated in section as follows: in the interior of a finger, an outwardly tapering cavity 14 is provided, which is surrounded by a core body 13.
- the core body 13 In order to give the core body 13 a high degree of inherent rigidity, it is made of a hard elastomer (for example 80 shore) with fibers, in particular carbon fibers, embedded therein. On this core body 13, further wrappings with increasing softness (for example 70, 60, 50, 40 Shore) are applied, of which only two wrappings 11, 12 are shown in FIGS. 3a and 3b.
- Such a construction of the separating element 1 requires a relatively small mass and thus a low inertia, so that it has a high angular velocity and much less energy than one
- Compressed air selection unit can be driven.
- the resulting noise emission can be reduced to below 70 db.
- the separation into the above-mentioned fractional streams cl, c2, c3 are described in more detail. If the fruit 51, which is referred to as ripe, healthy fruit, reaches between the fingers 10a and 10b, the stepping motor 2 receives no impulse from the main coordinate processor 4 or a controller downstream thereof, and the cargo 51 enters the fraction stream cl while the separating element remains in its initial position . If the fruit 52 already recognized as being too small in the approach zone a reaches the zone b between the fingers 10a and 10b, the stepping motor receives an acceleration pulse in the direction (counterclockwise in FIG.
- the separating agent 1 does not need to go back into the described starting position to be spent, since it is in an identical position.
- the selection of products 53 in the fraction control stream c3 is carried out in an analogous manner with the separating means 1 rotating in the opposite direction and requires no further explanation here. It is also easily possible within the scope of the invention, for example to separate foreign bodies from the sequential partial product stream, to impose a higher acceleration impulse to separate such a component on the separating agent 1 so that it can be separated into further partial fraction streams, so that the invention can be used not just limited to three streams.
- the real-time image tracking system also tracks the path of the products after the separation into the individual fraction partial streams cl, c2, c3 and feeds the signals (ejection distances) obtained in this way to a memory 41.
- These signals obtained are constantly compared with the predeterminable SoU values, which correspond to hits in the respective discharge channels or bands assigned to the fractional partial streams, which are otherwise not shown in detail.
- output signals adapted to the setpoint are generated in the memory and the stepping motor 2 is actuated in a modified manner with regard to its acceleration application.
- This measure is particularly important in the start-up phase of sorting a product batch and when changing between different products, since, for example, products of different masses of the same type experience different ejection distances with the same impulse.
- this measure has the advantage, however, that no structural changes need to be made to the overall device when a product is changed.
- the real-time Image tracking system 3 sequentieUe product streams that originate from several channels k captured simultaneously.
- Proximity zone a is upstream or partially includes it, and which, independently of the real-time image tracking system 3, enables independent external product detection and the signals obtained are also assigned to the data of the real-time image tracking system 3 in relation to individual products and fed to the main coordinate processor 4.
- Such a combination is sinvoU if outside product recognition is desired.
- the task of external product detection can also be assigned to the real-time image tracking system 3 in an integrated manner, but at least two such real-time image tracking systems 3 are then to be provided, which, opposite one another, detect the products at different angles, comparable to an arrangement according to DE 196 46 753.5, and theirs supply information obtained to a common evaluation and control unit 4, 40, 41, 42.
- the invention is not limited to the described embodiments in their entirety and in detail.
- the separating element 3 described can also intervene, for example from above, on products lined up in fixed routes.
- the design of the fingers 10 can also deviate from the circular design described, e.g. are flattened if, for example, products are to be sorted that are not injured or damaged on the surface by such a finger design.
