    Figure 1 schematically shows a top view of the known sorting device 1, which performs the known method. The sorting device 1 is provided with a transport device 2. The transport device 2 is built up of a plurality of endless conveyor belts 2-1, 2-2, ... running in parallel. 2-n. n is a random number, but in this figure n is set to 20. The conveyor belts 2-1; 2-2; ...; 2-n are controlled at the same speed. The top of each conveyor belt 2-1; 2-2; ...; 2-n are in the same transport plane. The length of the top of each conveyor belt (2-1; 2-2; ...; 2-n) can be reduced to create a temporary fall opening 6. In addition, the sorting device 1 is provided with a detection / selection device. 3. The detection / selection device 3 is provided with detection means for detecting the position of each product 5 in the transport device 1 and selection means for selecting a product 5. The sorting device 1 then comprises a control device for controlling the conveyor belts 2-1, 2-2; ...; 2-n for creating a drop opening 6. The products to be sorted 5 are each, by a different device (not shown), on one of the conveyor belts 2-1; 2-2; ...; 2-n, which transports the products in the indicated direction. The sorting device 1 then performs the steps of the following method.
    In step a) a product 5 to be discharged is detected and selected by means of the detection / selection device 3. In the figure, products 5 to be discharged are indicated as a circle with a white inner surface. The products 5 that must not be disposed of are indicated as a circle with a black inner surface.
    In step b) the endless conveyor belt 2-x is determined by means of the detection / selection device 3 on which the product 5 selected in step a) is located. In the current figure, these are the conveyor belts 2-3; 2-11; 2-15.
    In step c) the conveyor belts 2-3; 2-11; 2-15 determined in step b) are reduced so that temporary fall openings 6 are created for discharging the products 5 selected in step a).
    Figure 1 shows that in the known sorting device it can be said that each product 5 is supported by a maximum of one conveyor belt 2-x and that the products are aligned in the longitudinal direction of the conveyor belts, so that each product 5 is substantially in the is transported 2-x in the width direction of the conveyor belts in the middle of each conveyor belt.
    Figures 2A; 2B; 2C; 2D schematically show a top view of the inventive sorting device 10 according to the invention, which carries out the inventive method according to the invention. The sorting device 10 is provided with a transport device 20. The transport device 20 is made up of a plurality of endless conveyor belts 20-1; 20-2; ...; 20-n. n is a random number, but in this figure n is set to 20. The conveyor belts 20-1; 20-2; ...; 20-n are controlled at the same speed. The top of each conveyor belt 20-1; 20-2; ...; 20-n are in the same transport plane. The length of the top of each conveyor belt (20-1; 20-2; ...; 20-n) can be reduced to create a temporary drop opening 60. In addition, the sorting device 10 is provided with a detection / selection device 30. The detection / selection device 30 is provided with detection means for detecting the position of each product 50 in the transport device 10 and selection means for selecting a product 50. The sorting device 10 then comprises a control device for controlling the conveyor belts 20 -1; 20-2; ...; 20-n for creating a drop opening 60. The product 50 in this figure is larger than the width of a conveyor belt 20-x. The products 50, in particular all products 50, lie randomly on the transport device 20, each product 50 being carried by a plurality of conveyor belts 20-x and transported in the indicated transport direction, in this case by four conveyor belts 20-x. In Figure 2A, the products 50 are detected and selected by the detection / selection device
    30. A selected product 50 to be disposed of is indicated as a round white disk. A product 50 that does not have to be disposed of is indicated as a black disk. In Figure 2B, the products 50 are transported further in the transport direction, with some unselected products 50 leaving the sorting device 50 on the right-hand side. In Figure 2C, conveyor belts 20-9; 20-10; 20-11; 20-12 are simultaneously reduced, resulting in a fall opening 60. The selected (white) product 50 falls down through the conveying surface via the drop opening 60 and is removed from the sorting machine in a known manner.
    In Figure 2D, the conveyor belts 20-9; 20-10; 20-11; 20-12 are placed back to the starting position, so that the unselected products 50 can leave the sorting machine on the right-hand side.
    As can be seen from Figures 2A - 2D, the products 50 have such an outer dimension, in this case an outer diameter, that is chosen and / or adjusted to the width dimension of the conveyor belts 20-x, that the products 50 are always, or in any case, are supported and transported by several conveyor belts 20-x at the same time. Also, due to the chosen outer dimensions of the products 50, it cannot be said that a single conveyor belt 20-x, viewed in the width direction, supports two or more products 50, or at least does not fully support them. Figure 3A and Figure 3B show a cross-section of a conveyor belt 200 that is designed as a shooting belt. The conveyor belt 200 can be used as conveyor belt 20-x in the inventive sorting device 10. The conveyor belt 200 is mounted by means of guides 201; 202; 203; 204 and 205 as an endless belt. Conductors 204 and 205 are simultaneously movable parallel to the top of the conveyor belt 200. To that end, guides 204 and 205 are rigidly connected to each other via a rigid connection 210. Preferably, the conveyor belt 200 is placed between other conveyor belts, so that products can be supplied and supplied. removed. If a product is to be discharged, the conveyor belt 200 is reduced by moving the guides 204 and 205 against the conveying direction. This creates an opening between the conveyor belt 200 and the discharge conveyor belt, through which a product on the conveyor belt 200 will be transported to the opening 211.
    Figure 4A and Figure 4B show a cross-section of a conveyor belt 300 that is designed as a pinball machine. The pinball has a strong resemblance to a pinball machine. The conveyor belt 300 can be used as a conveyor belt 20-x in the inventive sorting device 10. The conveyor belt 300 is mounted by means of guides 301; 302 as an endless belt. Guide 302 is movable to the underside of the conveyor belt 300. Preferably, the conveyor belt 300 is placed between other conveyor belts, so that products can be supplied and discharged. If a product is to be discharged, the conveyor belt 300 is reduced by moving the guide 302 toward the bottom of the conveyor belt 300.
    This creates an opening 311 between the conveyor belt 300 and the discharge conveyor belt, through which a product on the conveyor belt 300 will be transported to the opening 311.
    Figure 5A and Figure 5B show a cross-section of a conveyor belt 400 that serves as an alternative to the conveyor belt 300 of Figure 4A and Figure 4B. The conveyor belt 400 is mounted by means of guides 401, 402 as an endless belt. Guide 402 is movable to the top of the conveyor belt 400. If a product is to be discharged, the conveyor belt 400 is reduced by moving the guide 402 toward the top of the conveyor belt 400. This creates an opening 411 between the conveyor belt 400 and the discharge conveyor belt, through which a product on the conveyor belt 400 will be transported to the opening 411.
    The conveyor belts 20-x in Figs. 2A - 2D are shown as belts with a substantially flat top surface which are arranged next to each other substantially without a gap, but if desired, it can also be said that the conveyor belts are designed as relatively narrow strings which can be arranged next to each other at a certain gap. This is shown in figures 6A - 6D, wherein only the differences with the sorting device of figures 2A - 2D will be explained and for a further description of the device of figures 6A - 6D the description belonging to figures 2A - 2D will be explained. referred. In figures 6A - 6d, the same reference numerals for identical parts are used as in figures 2A - 2D, but then increased by 1000.
    The sorting device 1010 according to the second embodiment of Figs. 6A-6D differs, as indicated above, from the sorting device of Figs. 2A-2D in that the conveyor belts are designed as belts. The transport device 1020 is made up of a plurality of parallel conveyor belts 1020-1; 1020-2; ...; 1020-n. n is a random number, but in this figure n is set to 21. The conveyor belts 1020-x are arranged side by side with a mutual center distance A. As can be seen from Figures 6A-6D, all products 1050 have an outer dimension, in this case an outer diameter, in a plane parallel to the conveying plane that is greater than the total or total center-to-center distance between four adjacent conveyor belts, or greater than three times the center-to-center distance A. As a result, the products 1050 are always transported simultaneously by several conveyor belts 1020-x, in this case always by at least three adjacent conveyor belts 1020-x or some products 1050 by four neighboring conveyor belts 1020-x, depending on the position of the products 1050 on the transport device 1020.
    In Figure 6C, conveyor belts 1020-10; 1020-11; 1020-12 are simultaneously reduced, resulting in a fall opening 1060. The selected (white) product 1050 falls down through the conveying surface via the drop opening 1060 and is removed from the sorting machine in a known manner.
    Similar to what has been explained with reference to Fig. 3, the conveyor belts from Figs. 6A - 6D can be designed as firing strings.
    The invention is expressly not limited to the embodiments shown. All combinations and kinematic reversals of the described technical measures are expressly covered by the invention. The invention therefore extends to any embodiment that falls within the scope of the scope of protection as defined in the claims and viewed in the light of the foregoing description and accompanying drawings.
