Description

[0001] Collection device for determining the distribution of agricultural grit

[0002] The invention relates to a collecting device for determining the distribution of agricultural spreading material and the use of such a collecting device for determining the distribution of agricultural spreading material.

[0003] When spreading agricultural spreading material, particularly fertilizer granules, the spreading pattern depends on the flow and flight behavior of the spreading material. This depends on the grain size, grain shape, true density, bulk density, and grain strength. It can also depend on other parameters. In principle, there are recommended setting values ​​for different spreading materials and different application situations, which can be retrieved from databases or read from so-called spreading tables, taking the respective spreading material into account. However, deviations from the expected spreading pattern can occur, for example, due to variations in the quality of the spreading material. Consequently, the distribution of agricultural spreading material must be tested in practice. To determine the distribution of agricultural spreading material, it is common practice to use a collecting device to collect the spreading material and then determine its distribution.

[0004] For this purpose, it is known to design a collecting device for collecting and retaining the spread material and to determine the distribution of the spread material on it. For example, adhesive mats for this purpose are known from EP 3 576 515 B1 and measuring bowls from DE 10 2004 017 075 A1. An example application is known, for example, from EP 2 923 546 B1.

[0005] The invention is based on the object of providing an improved collecting device. The invention comprises a collecting device according to claims 1, 5, 10, and 14, as well as a use of such a collecting device according to claim 15. Further examples are specified in the dependent claims.

[0006] The collecting device for determining the distribution of agricultural spreading material comprises an edge element and a receiving element.

[0007] The edge element comprises an edge region which is designed to at least partially delimit the receiving element on at least one side, in particular during use thereof. In particular, the edge region can be designed to delimit the receiving element on one, two, three, four or more sides, in particular during use thereof. The receiving element comprises a collecting region for collecting and optionally for holding agricultural spreading material. In particular, the collecting region can have a plurality of knob-like elevations which are arranged in a grid in the collecting region. Such elevations can form a plurality of, in particular equally sized, collecting spaces in which the grains of the spreading material can be retained at the points where they impact the collecting area.The knob-like elevations can, for example, be in the form of rods, tongues, hooks or the like, which extend perpendicular to the surface of the receiving element. Alternatively or additionally, the receiving element can comprise other collecting spaces, for example through wall boundaries other than knob-like elevations, e.g. partitions arranged in a grid or the like. A collecting area can be made of a different material or the same material as the rest or another part of the receiving element, wherein the two materials are typically firmly connected to one another. The knob-like elevations and / or other wall boundaries, e.g. partitions, of a receiving element can consist of the same or one (or more) different materials than the rest of the receiving element. In particular, the receiving element can therefore comprise one or more materials or be formed from these.

[0008] Collection spaces suitable for a specific grit can have a diameter, particularly at the point with the smallest diameter parallel to the surface of the receiving element, that is between 2 times and 50 times, in particular between 2 times and 10 times, the average longest dimension of a grit particle or the longest occurring dimension of a grit particle. To determine the average longest dimension of a grit particle, the longest dimension of several grit particles can be measured and an average calculated from this. The average longest dimension of a grit particle, as well as the average size or size distribution, can be known or determined, particularly in order to be able to select a receiving element with a collection space suitable for the size of the grit particles.

[0009] The collecting device can be designed for two different application situations. For example, it can be designed for use with different fertilizers, in particular different fertilizer colors and / or different fertilizer grain sizes. Alternatively or additionally, it can be designed for use under different lighting conditions and / or in different crop heights and / or in various other situations, for example, for different spreading situations with the provision of different additional information or for different additional information. The collecting device can be flat. The receiving element and / or the edge element can also be flat.

[0010] An object (e.g. the collecting device or the receiving element) is “flat” can in particular mean that the dimensions of the object in two, in particular mutually perpendicular, directions (e.g. length and width) are significantly larger than in a third direction (e.g. height), which can in particular be perpendicular to the other two directions. The dimensions in the two directions can in particular be, for example, at least a factor of 3, 4, 10, 20, 30 or 50 larger. The third direction can be the direction in which the object has the smallest dimension. When determining the dimension, recesses and / or holes in the object can be disregarded. Likewise, when determining the dimension, protruding areas, in particular setup aids, such asStands, legs, particularly if they are foldable or extendable; alternatively, such protruding areas, particularly foldable or extendable ones, may only be taken into account in the folded and / or non-extended state.

[0011] The smallest dimension can therefore, for example, correspond to the smallest distance between two imaginary, mutually parallel planes between which the object could still be pushed (optionally without protruding areas or with the protruding areas folded in and / or not extended, but optionally including the collecting area if the receiving element is included). The vertical projection of the object onto a plane perpendicular to the direction of the smallest dimension of the object can in particular be referred to as the "surface of the object."

[0012] The term “surfaces” of an object can be used to describe two mutually opposite upper boundaries of the object, which are typically (essentially) parallel to the surface of the object. The collecting area can be contained within these boundaries. Thus, surfaces can in particular be used to describe two (essentially) mutually parallel surfaces the size of the surface of the object, viewed at a distance of the smallest extent of the object, which are obtained when the object is projected perpendicularly onto two imaginary parallel planes at a distance of the smallest extent, between which the object can still be pushed (optionally without protruding areas or with the protruding areas folded in and / or not pulled out, but including the collecting area if the receiving element is included).

[0013] The collecting region can be flat. It can be formed along the surface of the receiving element or along a part of the surface of the receiving element. It can run (essentially) perpendicular to the direction of the smallest extent of the receiving element, in particular, for example, the direction of its smallest extent can run (essentially) parallel to the direction of the smallest extent of the receiving element. The collecting region, in particular its perpendicular projection onto the plane which lies perpendicular to the direction of the smallest extent of the object, can extend over a large part, for example at least 50%, for example at least 75%, for example at least 80%, or at least 90%, for example 100%, of the surface of the receiving element.

[0014] A collecting device can have a height (direction of smallest dimension) of between 0.2 cm and 5 cm, in particular between 0.5 cm and 2.5 cm, in particular between 0.8 cm and 1.2 cm. The width and length of the collecting device (perpendicular to each other and both perpendicular to the height) can each be between 20 cm and 80 cm. In particular, the length can be, for example, between 40 cm and 80 cm and the width between 20 cm and 50 cm.

[0015] The width and length of the collection area (perpendicular to each other and both perpendicular to the direction of the collection area with the smallest extent of the collection area and / or the collection device) can each be between 20 cm and 70 cm. In particular, the length can be between 40 cm and 65 cm, and the width between 20 cm and 50 cm, for example.

[0016] The collecting device can be designed in one part, two parts, or several parts.

[0017] For example, a one-piece collecting device can comprise an edge element and a receiving element that are formed as a single connected part, in particular made from one material, and / or consist of two or more firmly connected parts that are optionally made from different materials. “Firmly connected” can in particular mean that two or more elements, e.g. edge element and receiving element, have been produced as separate parts that are connected to one another by means of a fastening means so that they can no longer be separated from one another without aids (whereby hands are not counted as aids) and / or non-destructively. For example, the edge element and receiving element can be firmly connected to one another by means of an adhesive, a connection by means of solvent bonding, a mechanical connection such as by screwing and / or welding.

[0018] In a two- or multi-part collecting device, two or more parts, e.g., edge element and receiving element, can be designed as two or more separate parts that are designed to be in contact with each other during use. Two or more separate parts can be in contact with each other, particularly when used without connecting means, or can be connected to each other via one or more detachable connecting means, in particular, can be connected to each other in a non-destructively detachable manner.

[0019] The collecting device can comprise two parts made of different materials that are firmly connected or can be separated from each other without destruction.

[0020] The edge element and the receiving element can be formed as two separate parts. A collecting device in which the edge element and the receiving element are formed as two separate parts can allow the use of different materials for the edge element and the receiving element, e.g., a softer material for the receiving element than for the edge element.

[0021] In the case of a multi-part, e.g. three-part, collecting device, several, in particular alternative, parts can be comprised by the collecting device, for example in the case of a three-part collecting device, an edge element and two receiving elements.

[0022] For example, the receiving element and the edge element can be non-destructively detachable and / or connectable to one another. For example, the receiving element and the edge element can be placed on top of one another, hung into one another, or fastened to one another by means of connecting means. In addition to the edge region, which is designed to at least partially delimit the receiving element on at least one side, the edge element can comprise further regions or structures, for example an opening, recess, or net- or grid-like structure into which the receiving element can be placed, hung, or otherwise fastened or inserted.

[0023] Alternatively or additionally, a receiving element may comprise a transparent surface, in particular with knobs or compartments, and an exchangeable property element may be insertable into the receiving element in order to change the color, fluorescence or other properties of the receiving element, in particular for different application situations.

[0024] The edge element and the receiving element can comprise matching connecting means with which they can be connected to one another. For example, the edge element can comprise hooks, hook-and-loop fasteners, eyelets, openings, tabs or the like, which can be connected to corresponding counterparts on the receiving element, e.g., eyelets, hook-and-loop fasteners, hooks, tabs or the like. The receiving element and edge element can be connected to one another by connecting means, for example, positively or non-positively, via hook-and-loop fasteners and / or other connecting means. They can be connected to one another in such a way that, when connected, they cannot be moved relative to one another in at least one, e.g., at least two, three, four or more directions.“Non-destructively detachable” can in particular include that the edge element and the receiving element can be separated from each other non-destructively and optionally without further aids (hands not being considered aids).

[0025] The edge element can be designed, for example, in the form of a mat or a flat cuboid, with an edge region and a central region. The central region can be designed to receive the receiving element, i.e. in particular can be designed so that the receiving element can be inserted. For example, it can have the same shape as the surface of the receiving element, but be more than 1%, in particular more than 2%, larger. The central region can be designed as a recess in the edge element that is open to one side of the edge element. For example, an edge element, in particular, for example, a mat or a flat cuboid, can be thinner in the central region than in the edge region or can be perforated in the central region, e.g., have an opening.

[0026] In some examples, the central region may comprise a grid-like or sieve-like structure or similar instead of the recess into which the receiving element can be inserted. Optionally, the receiving element may, for example, comprise matching counterstructures to the grid-like structure, e.g., recesses into which the grid-like structure can engage or be inserted.

[0027] The collecting device can comprise two collecting areas. The collecting areas can be arranged next to one another, in particular as partial areas arranged next to one another or in proximity to one another (e.g., of the same size or different sizes) on a receiving element, and / or can be arranged along, in particular opposite, surfaces of the receiving element. Alternatively, two collecting areas can be comprised by different receiving elements.

[0028] The two collection areas can have different properties. For example, they can have different colors (e.g., complementary colors) or different brightnesses (e.g., black and white) and / or be designed for different grain sizes. Designing them for different grain sizes can, in particular, include knob-like elevations with different spacing, so that collection spaces of different sizes are created in the different collection areas, or the size of the collection spaces in the different collection areas can otherwise be different.

[0029] The receiving element can, for example, be designed to be reversible. "Reversible" can in particular comprise that it comprises two mutually opposing surfaces, each comprising a collecting region, wherein the collecting regions comprised on the mutually opposing surfaces can in particular have different properties. Thus, in particular in the case of a one-piece collecting device, the collecting device as a whole can be turned in order to be able to use a collecting region with a different property. In the case of a receiving device where the receiving element and edge element are separate parts, a reversible receiving element can be turned if it is not connected to the edge element or inserted into it. It can then be inserted into an edge element lying on the ground with the collecting region selected for use facing upwards.

[0030] In other examples, particularly in three-part examples, of collecting devices, the receiving element can be interchangeable, so that with different receiving elements of the collecting device the collecting device is suitable for different application situations.

[0031] The collecting device, in particular an edge region, a collecting region and / or the two (or more) collecting regions, can optionally comprise one or more additional information items and / or a receptacle for additional information(s), and can thus be designed in particular for two different application situations.

[0032] Such additional information can, for example, comprise a marking. A marking can, in particular, comprise a color marking, a pattern, a QR code, color coding and / or another form of optical identification. It can, for example, allow recognition of which collecting device, e.g. which edge area and / or which collecting area(s) are currently visible, in particular can currently be used. The additional information or the receptacle for additional information(s) can, in particular, also comprise information about the color of the collecting device or part thereof. This information about the color of the collecting device or part thereof can then, for example, be used to compare it with the expected color.

[0033] Additional information(s) can be included on the receiving element(s), in particular on the collecting area(s), in order to distinguish them from one another. If a collecting area comprises knob-like structures, one or more additional information items can be included, for example, as recesses in the knob-like structures, as a marking of the knob-like structures. Alternatively or additionally, additional information can be included in the edge element, e.g., in the form of a marking.

[0034] A receptacle for additional information can be included in the edge element and / or the receiving element. It can be designed, in particular, as a display, e.g., for displaying a QR code, serial number for tests, installation position, in particular GPS position, and / or other text, as one or more lamps, in particular LED lamps, or as a receptacle or recess for a marking, e.g., color charts, QR codes, or text.

[0035] The collection device can be designed for use in tall crops. A "tall crop" here can include, in particular, a crop (e.g., in a field) that is higher than 5 cm, for example, higher than 10 cm, for example, higher than 20 cm, especially higher than 50 cm. The height specification always refers to the average height of the crop in the field or in a sub-area of ​​the field, in particular the sub-area in which the distribution of the agricultural spreading material is to be determined.

[0036] The collecting device can be designed in particular such that it comprises one or more support elements, particularly on the edge element and / or receiving element. Such a support element can comprise one or more stands and / or fold-out and / or extendable standing aids or can be designed as such.

[0037] A stand can, for example, comprise one, two or more permanently attached legs or be designed as such, or comprise an extendable stand or be designed as such, which is extendable, for example, like the stand of an ironing board, i.e. by two legs being connected to one another via a central joint, one of the legs being connected to the underside of the collecting device via a fixed joint and the other leg via a movable joint, and wherein the movable joint is designed to be displaceable parallel to the underside of the collecting device. Fold-out standing aids can, for example, comprise several, e.g. two, four or more, standing aids.For example, two fold-out standing aids can be designed like the stands of a beer table, i.e. they can comprise two fold-out stands which can be fastened in a position parallel to the collecting device and, after loosening the fastening and moving the stands into a folded-out position, can be fastened in this position, in particular perpendicular to the collecting device.

[0038] Alternatively or additionally, fold-out standing aids can, for example, comprise four or more fold-out legs which, in the folded-in position, lie along the edge element and / or the receiving element and, in the unfolded position, can enclose an angle, e.g. of approximately 90°, with the surface of the receiving element, e.g. between 45° and 135° or between 75° and 105°. Extendable standing aids can, in particular, for example, be extendable like a telescope and optionally be designed such that they can be adjusted to different lengths, e.g. two, three or more lengths, and can be fixed at these lengths, i.e. are sufficiently stable, in particular at these lengths, to stabilize the fall arrest device during use. For example, extendable standing aids can optionally also be foldable, i.e. can be extendable and folded in like a telescope.

[0039] Extendable stands and / or foldable and / or extendable standing aids can, for example, be arranged so that the fall arrest device can be used with the stand extended and not extended and / or with the standing aids folded out and in, and / or with the standing aids folded out and in, i.e., in particular in different situations. Typically, the standing aids are designed to a length or can be extended or folded out to a length that allows them to be placed through the crop onto the field surface and / or are long enough to be stabilized by the crop (even without contact with the field surface).

[0040] The collecting device can include an indicator for horizontally aligning the collecting device, which can be particularly suitable for horizontally aligning the collecting device in high stands. The indicator can be arranged in the edge area and / or the receiving area. It can be designed, for example, as a spirit level indicator, in particular as a round spirit level or two, optionally mutually perpendicular, elongated spirit levels, as an electronic display, and / or similar.

[0041] The collecting device can have a large contact surface with a low weight, making it particularly suitable for use in high stands. In particular, the collecting device can have a weight per surface of less than 50 kg / m 2 , e.g. less than 25 kg / m 2 , e.g. less than 10 kg / m 2 , in particular less than 5 kg / m 2 , e.g. less than 1 kg / m 2 have.

[0042] The collecting device, in particular the edge element and / or the receiving element, can comprise a device for influencing the lighting conditions, in particular the lighting conditions when photographing the collecting device. By means of a device for influencing the lighting conditions, the collecting device can be designed, in particular, for two different application situations, e.g., with more or less light.

[0043] For example, the device for influencing the lighting conditions can comprise lighting, which can be designed in particular to illuminate at least part of the receiving element, e.g. at least part of the collecting area, in particular the entire collecting area. The lighting can thus allow the collecting device to be used even in unfavorable lighting conditions. Such lighting can, for example, comprise one or more LEDs, LED tapes, LED strips and / or other lamps. The lighting can be controllable so that its brightness can be adjusted. For example, it can be adjustable in specific steps or continuously. For example, the lighting can be controlled via one or more switches or buttons on the collecting device or can be wirelessly controllable via a wireless connection, e.g. via Bluetooth, WiFi or another connection.For example, control via a mobile device, e.g. a smartphone, can be enabled. In particular, the lighting can be controllable so that only parts of the lighting are activated individually. Alternatively or additionally, the lighting can be controlled by an internal control loop in the capture device, e.g. depending on detected ambient lighting. For this purpose, the capture device can comprise a brightness sensor or light sensor, for example. By controlling the lighting, in particular controlling it so that the lighting conditions meet predetermined conditions when the image is captured, comparable lighting conditions can be created, particularly when multiple images are captured.

[0044] The lighting may comprise lighting on at least one side of the collecting device.

[0045] For example, lighting on at least one side of the collecting device may include lighting on at least one side of the edge element and / or the receiving element.

[0046] "Illumination on at least one side of an object," e.g., the collecting device, the edge element, and / or the receiving element, can in particular include or mean that an illumination is arranged away from the center of gravity of the surface of the object. For example, one or more point-shaped, linear, or other illuminations can be included along an imaginary, in particular straight, line or other geometric figure, e.g., a semicircle or circular arc, on at least one side of the object.

[0047] In particular, lighting on at least one side of an object can comprise lighting that is arranged and / or controllable on one side, in particular in a point-like manner or along a straight line, and in particular only on one side, in particular in a point-like manner or along a straight line and / or is controllable. For example, by switching on the lighting, the spreading material lying on the collecting device can be illuminated from one side and the cast shadows can be recorded by a camera. The cast shadows, optionally together with further information about the collecting device such as the area, dimensions or active area of ​​the collecting area, i.e. the area of ​​the collecting area in which the spreading material is collected, can thus enable an evaluation of the spreading pattern of the spreading material.In particular, the grain sizes, in particular a grain size distribution, can be determined by means of the cast shadows, especially if further information about the collecting device, e.g. the dimensions, is known.

[0048] The collecting device can comprise lighting around the collecting region of a receiving element. In particular, the lighting can be provided on multiple sides of the collecting region, in particular in a line or curve, e.g., circular, around the collecting region of the receiving element. For example, in the case of a rectangular surface of the receiving element, in particular of the collecting region, the lighting can be arranged, for example, on two, three, or in particular four sides of the receiving element, in particular of the collecting region, in particular on the receiving element and / or the edge region of the edge element. Such a distribution of the lighting, in particular around the collecting region of the receiving element, can allow the most uniform illumination of the collecting region possible.

[0049] The collecting device can be fluorescent and / or reflective in at least one partial area and / or can comprise a planar light source, e.g. LED or OLED panel. For example, a collecting area can be fluorescent and / or reflective, which can lead to good illumination of the image when taking an image, e.g. using a camera with flash, and / or to the fact that grit located on the collecting area is recognizable as dark areas in the image. With a planar light source, which can be included in particular along the collecting area, the grit located on the collecting area can also be recognizable as a dark area in the image, in particular regardless of any darkening.A flat illuminant, like a fluorescent collection area, can have a specific color or a specific color range, which can in particular enable good recognition of scattered material of certain colors, in particular, for example, the complementary color.

[0050] A collecting device that is fluorescent and / or reflective and / or includes a flat illuminating means can also make it easier to detect interfering objects, such as foreign bodies. The collecting device can also include one or more solar cells to power the device for influencing the lighting conditions. Alternatively or additionally, one or more batteries, particularly secondary batteries, can be provided for the power supply. A connection for an external power source would also be possible alternatively or additionally.

[0051] The invention further comprises a use of a collecting device described above for determining a distribution of agricultural spreading material.

[0052] The use can comprise, for example, in a reversible embodiment of the collecting area and / or three or more-part embodiments of the collecting device, a step of selecting the desired collecting area. Optionally, the use can further comprise attaching the receiving element with the collecting area to the edge element so that the desired collecting area is oriented upwards for use. Optionally, a step of removing an existing receiving element and / or turning a receiving element can be included beforehand.

[0053] Such use may include deploying a collecting device. Deploying the collecting device may, in particular, include deploying the collecting device in a high position, e.g., by horizontally deploying it using an indicator for horizontally aligning the collecting device.

[0054] Optionally, one or more stands and / or standing aids can be used, in particular, for example, folded out and / or extended, in particular extended to the correct length.

[0055] The collection device can then be sprinkled with agricultural grit, e.g. when driving over the field.

[0056] The use may include controlling the lighting of the collection device, for example, using a mobile device, e.g., a cell phone. Alternatively, the use may include automatic control of the lighting based on (measured) lighting conditions, e.g., using a (brightness) sensor included in the collection device or a mobile device.

[0057] The use may alternatively or additionally comprise taking an image of the collecting device covered with agricultural spreading material and using this to determine a distribution of agricultural spreading material. When taking the image of the collecting device, one or more additional pieces of information, e.g. markings, of the collecting device can be used to position the camera and / or to evaluate the image. The use may alternatively or additionally comprise removing the agricultural spreading material from the collecting device, in particular the receiving element, and collecting it, e.g. in a funnel, and measuring it volumetrically or by weight in order to determine a distribution of agricultural spreading material.

[0058] Further details and aspects of the invention are described in the following figures (not to scale).

[0059] Figures 1a, 1b show an exemplary collecting device;

[0060] Figures 2a - 2f show exemplary edge and receiving elements;

[0061] Figures 3a - 3c collecting devices and receiving element with additional information;

[0062] Figures 4a, 4b show an exemplary collecting device for use in high stock;

[0063] Figure 5 shows a collecting device with a device for influencing the lighting conditions.

[0064] Figure 1a shows a plan view of an exemplary collecting device 1. The collecting device comprises an edge element 2 and a receiving element 3. In the example shown, the collecting area extends, for example, over the entire surface of the receiving element 3.

[0065] By way of example, the collecting device is shown as being formed in one piece, in particular from a single material. In other examples (not shown here), the collecting device can be formed in one piece, in particular from two or more than two, firmly connected parts. For example, the receiving element 3, in particular, for example, the collecting region 3a (and / or one or more further collecting regions, e.g., a collecting region 3b optionally arranged on the rear side) can be formed from a different, in particular softer, material than the edge element 2, in particular the edge region 2a of the edge element 2.

[0066] Edge region 2a is designed to delimit the receiving element 3 on at least one side, in Figure 1a in particular on four lateral sides, for example, which can be designed, for example, as an imaginary connection of the lines ai, a2, a5, a4 (and optionally on the back, for example, as an imaginary connection of lines bi, b2, b3, b4). The sides of the receiving element 3 can, as in this example, coincide with the sides of the collecting region 3a, but this does not have to be the case. Also shown are optionally present openings 2b, which can, for example, facilitate or enable transport, e.g. lifting, and / or storage, e.g. hanging up, of the collecting device. In other examples (not shown), the collecting device can also comprise no openings 2b, one opening 2b or more than two openings 2b.

[0067] Figure 1b shows a cross-section through line A of the collecting device 1 from Figure 1a. Shown are, by way of example, edge regions 2a of the edge element on two opposite sides of the collecting device 1, as well as collecting regions 3a and 3b of the receiving element 3. In the example shown, the receiving element 3 comprises two collecting regions 3a, 3b, which are arranged on opposite sides of the receiving element 3. The receiving element 3 is thus designed to be reversible. The two collecting regions 3a, 3b can have different properties. In particular, they can comprise collecting spaces of different sizes, as in this example, and can thus be designed in particular for receiving grit of different sizes.

[0068] Figure 2a shows an exemplary edge element 4, comprising an edge region 4a, an optional opening 4b, a central region 4c with optional connecting means 4d.

[0069] Central region 4c is designed here in the form of a recess in the edge element. Four connecting means 4d are shown here as an example, each arranged away from the center of gravity of the surface of central region 4c in the direction of the four corners of central region 4c. The connecting means 4d can be suitable for establishing a connection to a collecting element by gluing, magnetic connection, plugging, form-fitting, clipping, or other connection options. The connecting means 4d can, for example, be designed as one half of a hook-and-loop fastener. In other embodiments, more or fewer than four connecting means can optionally be arranged at other locations in central region 4c.

[0070] Figure 2b shows a section through edge element 4 from Figure 2a along the line B with edge region 4a, optional opening 4b and central region 4c in the form of a recess into which a receiving element can be inserted.

[0071] Figure 2c shows a schematic plan view of an exemplary receiving element 5. In this example, the receiving element 5 comprises a collecting region 5a with a plurality of collecting spaces, wherein the collecting region can optionally be arranged over the entire surface of the receiving element. The receiving element 5 is designed to be used together with an edge element, in particular edge element 4, e.g., to be inserted into a central region, in particular a recess, as shown in Figures 2a, 2b. In the inserted state, the receiving element in the example shown is delimited on the four lateral sides by the edge element 4.

Recording elements with different properties can each comprise different additional information. Thus, the additional information can, for example, enable recognition of the properties of the receiving element, e.g., the size of the receiving spaces, the color, and / or other properties, and thus enable targeted selection of the receiving element for use and / or enable targeted selection of a recording and / or evaluation algorithm.Figure 3c shows a collecting device 10, for example, formed as a single piece, wherein an edge element with edge regions 10a delimits the receiving element 10c on at least one side, here in particular the sides corresponding to the boundaries a2, a4, ae, and as. The collecting device 10 can comprise additional information 10b, which can be defined, for example, by the shape and length of the lateral boundaries ai - as of the receiving element 10c, the shape of the edge region 10a, and / or the shape and position of an optional receptacle for additional information 10b. The collecting device 10 can optionally comprise two firmly connected parts made of different materials, wherein, for example, the collecting region 10c of the receiving element can be formed from a softer material than the edge element with edge regions 10a.

[0083] Figure 4a shows an exemplary edge element 11 of a collecting device for use in high-rise areas. The edge element 11 comprises an edge region 11a and a recess 11b for a receiving element. Optionally, the recess can contain a receiving element, which can be optionally connected to the edge element either firmly or loosely (not shown).
