Abstract
Description
[0001] The invention relates to a weight detection device and two methods for equipping a measuring object with such a weight detection device.
[0002] Weight measurement plays an important role in many areas of life. For example, in agriculture or the construction industry, load cells are used to record the weight of a silo container because they are relatively robust and can measure even heavy weights very precisely. A weight detection device with a corresponding load cell is arranged under each leg of such a silo container. By constantly monitoring the weight of the silo, the time when the contents need to be refilled can be determined. Furthermore, such a weight detection device can be used to easily record the consumption of the supplies stored in the silo container or container. Load cells are therefore a component of well-known weight detection devices.
[0003] The structure of a load cell is relatively simple. It comprises a base body into which at least one measuring element is integrated. The measuring element is a measuring element that reacts to deformation. A strain gauge for such a measuring element is mentioned here merely as an example, although other measuring elements are also known. The load cell further comprises at least one deformation section, which deforms due to the weight acting on it and thus generates an electrically measurable output signal via the measuring element corresponding to the deformation. This output signal can be processed in evaluation electronics designed for this purpose and equipped with suitable software or interacting with it.In order to allow evasive movements of the deformation section, load cells of known design have a deformation distance between the deformation section and a corresponding counter surface, which is often designed as a deformation slot.
[0004] A known weight detection device with a load cell is disclosed, for example, in EP 0 952 436 A2. In the solution described in the document, several weight detection devices are placed beneath a container for holding agricultural products. However, this requires the container to be lifted by means of a crane before the weight detection devices can be arranged, which is very complex and, not least, costly due to the high weight of such a container, which can easily exceed 10 t. In this solution, each of the weight detection devices used consists of a base body, an additional, movable platform, and a separate deformation section that accommodates the platform. A bearing pin is also inserted into the platform, which ultimately rests against the underside of the container and thus supports the container.The container can be moved by approximately 1 to 2 mm from an initial position to a weighing position by securing several bolts, i.e., lifted by closing a gap between the deformation section and the base body that existed before the bolts were secured. The deformation section, with its contained load cell, forms a separate component that is connected to the base body in an additional work step and secured thereto in the manner described above. The weight detection device described in EP 0 952 436 A2 can only be used if the lifting movement of the container is very small.However, especially with silo containers, such as those used in agriculture or the construction industry, the ground is often relatively uneven, requiring significant height differences to be overcome in order to precisely align the silo container and thus achieve the most accurate weight measurement results. This is not possible with the design described in this publication. Furthermore, the weight measurement device presented here consists of numerous individual parts, making it very complex to manufacture and requiring considerable assembly effort.
[0005] As previously indicated, retrofitting existing measurement objects with a weight-measuring device poses a significant problem. Due to their high weight, these measurement objects often have to be lifted with a costly and labor-intensive crane in order to place the weight-measuring device underneath. This problem is well known. US 10,416,019 B2 provides a solution. The weight-measuring device comprises a frame fixed to the ground, in which a support block is arranged. This support block is attached to the side of the measurement object standing on the ground, for example, to a support leg of a silo container.An S-shaped load cell is fixed between the frame and the support block. A bolt penetrating the frame is screwed into its upper leg. This bolt also serves to mount the load cell in the frame at an adjustable height. By rotating the bolt, the measured object can thus be indirectly lifted, which disadvantageously places a tensile load on the load cell. This design variant is also very complex due to the large number of individual components and, in particular, the required frame.
[0006] US 2020 / 0323169 A1 discloses a weight detection device for determining the weight of a measurement object and comprising a load cell connected to the measurement object. The load cell consists of a base body and at least one measuring element located in a deformation section of the base body that can be deformed by the action of a weight force of the measurement object and that generates an electrically measurable output signal corresponding to the deformation, which can be processed in evaluation electronics. The deformation section is formed integrally with the base body and forms a component of a lifting device by means of which the measurement object can be transferred from an initial position to a weighing position.In this solution, the load cell's base body is not directly attached to the measurement object, but rather connected to the measurement object via an additional bracket and a leg holder that can be moved up and down within a cavity of the bracket using a threaded bolt. In other words, additional components are required to connect the load cell to the measurement object, increasing the assembly effort and making the overall design very complex.
[0007] WO 2018 / 039787 A1 describes a similar weight detection device, but in which the base body of the load cell is attached directly to the measurement object and a threaded bolt is used as a lifting device, which is screwed through a thread in the base body of the load cell. The threaded section of the threaded bolt rests on the ground. The load cell is also mounted in a holder so it can rotate about a pivot axis and can be raised or lowered together with the measurement object using the threaded bolt. The load cell performs a circular arc movement around the pivot axis. To fix the load cell at a desired height, an additional fixing bolt is required. This bolt is guided through another hole in the base body of the load cell and must be secured with an additional cotter pin.
[0008] Finally, CN 204405171 U discloses a weight measurement device in which the base body of the load cell is not directly attached to the measuring object, but indirectly. This device uses an S-shaped load cell and a tension load sensor, in which the load cell is suspended between a stationary holder and a holder attached to the measuring object.
[0009] The functionality of a weight detection device with a load cell for determining the weight of a silo container is also described in DE 10 2011 106 851 A1. In this document, a soft elastic material is inserted into the deformation gap between the substrate and the deformation section of the load cell, thus protecting the weight detection device from the effects of weather.
[0010] The invention is based on the object of providing a weight detection device for determining the weight of a measurement object, which has a simple overall design and allows for a larger lifting movement than is the case with previously known solutions, in order to compensate for unevenness in the surface if necessary. Furthermore, at least one method is to be specified for equipping a measurement object with such a weight detection device.
[0011] The invention solves this problem with the features of independent patent claims 1, 9 and 10.
[0012] Further embodiments of the invention are the subject of the respective subsequent subclaims.
[0013] A weight detection device for determining the weight of a measurement object, comprising at least one lifting device and at least one load cell connected to the measurement object, in which the load cell consists of a base body, a deformation section and at least one measuring element which is present in or on the deformation section formed on the base body and which is deformable by the action of a weight force of the measurement object and which generates an electrically measurable output signal corresponding to the deformation, which can be processed in an evaluation electronics, wherein the base body of the load cell is attached directly to the measurement object and the deformation section formed integrally with the base body is a component of the lifting device, by means of which the measurement object can be transferred from an initial position to a weighing position, was further developed according to the invention in such a way thatthat the lifting device, which is mechanically adjustable in length, consists of a pressure sleeve having a pressure flange which slides against a corresponding annular flange of the deformation section, wherein a threaded bolt is screwed into the pressure sleeve, the opposite end of which is fixed to the substrate, anchored in the substrate, or supported on the substrate.
[0014] The key advantage of the solution according to the invention is that the entire weight detection device consists of only a few individual parts and is therefore extremely simple in design. Furthermore, the solution presented enables a considerably greater lifting distance compared to known solutions, which is useful because it allows uneven surfaces beneath the object to be weighed to be easily compensated for. The core of the invention, however, is that the base body of the load cell is attached to the object to be weighed, which can particularly advantageously be done retrospectively, i.e., when the object to be weighed is already present and / or set up. Since the deformation section is also a component of the lifting device, the implementation of the lifting movement is very direct and allows a considerably greater lifting distance than was previously possible.This makes the weight detection device highly flexible in its use, as the base body only needs to be attached to the measuring object, without the need for additional components such as a frame. The simple design of the weight detection device according to the invention also makes it easy to shield it from contamination or weather influences. This is particularly advantageous for outdoor use and can be achieved, for example, by simple encapsulation or by attaching or fitting a cover.A particularly simple embodiment of a weight detection device according to the invention is that the lifting device, which is mechanically adjustable in length, consists of a pressure sleeve having a pressure flange that slides against a corresponding annular flange of the deformation section, wherein a threaded bolt is screwed into the pressure sleeve, the opposite end of which is fixed to the substrate. The pressure sleeve is inserted into suitable through-openings provided in the connecting flanges and connected to the deformation section, so that the pressure flange of the pressure sleeve rests against the corresponding annular flange of the deformation section.
[0015] This mechanical solution is insensitive to weather influences and, moreover, easy to handle. A power supply or hydraulic or pneumatic lines are unnecessary. It is particularly advantageous according to the invention that the base body of the load cell is attached directly to the measurement object and that the deformation section, which is formed integrally with the base body, is part of a lifting device by means of which the measurement object can be transferred from an initial position to a weighing position. "Direct" in this case means that no intermediate elements are required, which considerably simplifies the inventive attachment to the measurement object and the construction of the weight detection device. The one-piece design of the base body with the deformation section formed thereon represents a very simple load cell. The base body can also have connecting flanges formed integrally therewith, suitable for fixing the load cell to the measurement object.
[0016] A further development of the invention is that the base body is attached laterally to the measuring object placed on a base, and the lifting device coupled to the deformation section rests on the base with its side facing away from the deformation section or is anchored in the base. The anchoring does not have to be below the measuring object, but can particularly advantageously be provided laterally next to the measuring object, which significantly simplifies installation, i.e., the connection of the weight detection device to the measuring object. A crane for lifting the measuring object is thus unnecessary. If the mechanical design of a weight detection device has a threaded bolt, the end opposite the thread of the threaded bolt can lead to a base, which according to a further embodiment of the invention is designed, for example, as a ball joint.The ball joint design allows movements to be compensated and the assembly of the entire weight measurement device is thus considerably simplified.
[0017] For a weight detection device according to the invention, load cells with an S-shape, a T-shape, an E-shape, or an comb-shape, for example, can be used. T-shaped or E-shaped load cells have proven to be particularly advantageous because they have a base body that can be easily connected to the measurement object and the lever arm acting on the measurement object is short, so that the load on the measurement object is reduced when raised, i.e. in the weighing position. With such load cells, at least one bore can also be made in the base body through which a screw bolt is passed in order to fix the load cell directly to the measurement object. This is particularly advantageously a detachable connection, so that the load cell can also be replaced if necessary.
[0018] In the pursuit of simplified assembly of the weight detection device according to the invention on the measurement object, it is further proposed that at least one connecting flange for fixing the load cell to the measurement object be formed on the base body of the load cell. In this case, the connecting flange can be designed in a particularly advantageous manner as a component of the base body, i.e., formed integrally with the base body. In this way, the manufacture of the entire load cell can be further simplified. In the simplest case, the connecting flange consists of a web formed from the base body, into which a bore or thread is introduced, whereby a detachable connection to the measurement object can preferably be created if a corresponding bolt, pin, or rivet is present on the measurement object or is introduced into the measurement object.
[0019] To ensure sufficient deformability of the deformation section, it is also helpful to create a deformation gap between the connecting flange and the deformation section. This can be a cavity, a recess, a gap, or a slot.
[0020] According to a very specific embodiment of the invention, the measuring object can be a silo container with at least three legs, each equipped with a weight-measuring device. Such silo containers are used, for example, in agriculture for storing feed, grain, or silage—in other words, more generally for storing loose, pourable, or free-flowing products. They are also used in the construction industry, for example, for holding cement and other goods. The continuous measurement of the weight of such silo containers is important in order to be informed of the current fill level at all times. The available evaluation electronics, which are capable of immediately evaluating and displaying the recorded values, assists in this process.
[0021] A first method according to the invention for equipping a measurement object with a weight detection device, which in turn comprises a load cell having a base body with at least one deformation section formed integrally thereon and having a measuring element and at least one connecting flange, is characterized by the following method steps: -Anchoring of a threaded bolt forming part of a lifting device to or in the ground, -Establishment of a connection between the threaded bolt and a pressure sleeve inserted into the deformation section of the load cell, which forms another component of the lifting device, -Fixation, preferably direct fixation of the base body of the load cell to the side of the measuring object placed on the ground, -Initiation of a rotational movement of the pressure sleeve, so that a relative movement between the pressure sleeve and the threaded bolt leads to a lifting movement of the measuring object, by which the measuring object is transferred from an initial position to a weighing position.
[0022] An alternative method according to the invention for equipping a measurement object with a weight detection device, which in turn comprises a load cell, with a base body with at least one deformation section formed integrally on the base body and having a measuring element, and at least one connecting flange, is characterized by the following method steps: -Fixation, preferably direct fixation of the base body of the load cell to the side of the measuring object placed on a surface, -Screwing a threaded bolt forming part of a lifting device into a corresponding thread in the deformation section of the load cell, -Installation or anchoring of the end of the threaded bolt opposite the thread of the threaded bolt on or in the subsoil, -Initiation of a rotary movement of a hexagon nut screwed onto the thread of the threaded bolt, so that the relative movement leads to a lifting movement of the measuring object, by which the measuring object is transferred from an initial position to a weighing position.
[0023] As can be seen from the previously described methods according to the invention, they are characterized by only a few process steps and are therefore very easy to implement. A very significant advantage in this case is that the weight detection device can also be retrofitted to existing measurement objects, without, for example, requiring a costly and labor-intensive crane to lift the measurement object and place the weight detection device underneath it. The weight detection device is simply attached to the side of the measurement object, thus allowing the entire measurement object to be lifted using simple means.
[0024] A further embodiment of the method according to the invention is that after the initial transfer of the measuring object into its weighing position, a calibration is carried out so that weight changes of the measuring object can subsequently be recorded and electronically processed by means of the weight recording device.
[0025] The invention is explained in more detail below with reference to the accompanying drawings. The exemplary embodiments shown do not represent a limitation to the variants shown, but serve merely to explain a principle of the invention.
[0026] Identical or similar components are always designated by the same reference numerals. To illustrate the functionality of the invention, the figures show only highly simplified schematic diagrams, omitting components that are not essential to the invention. However, this does not mean that such components are not present in a solution according to the invention.

[0028] In the Fig. 1 shows an example of a measuring object 2 that is equipped with several weight detection devices 1. The measuring object 2 is a silo container, such as is suitable for holding agricultural products. The silo container 2 has a filling opening 17, which serves to fill it with the products to be stored. On the side opposite the filling opening 17, there is also an outlet 20, which allows the removal of the products contained in the silo container 2. For this purpose, the outlet 20 is designed to be closable. The silo container 2 consists of a circular cylindrical container section 18 and a tapered section 19 adjoining it in the direction of fall of the product, which has the aforementioned outlet 20 on its underside. For setting up the silo container 2, it has Fig. 1 has a total of four support legs 16, each of which has a weight detection device 1. Each of the weight detection devices 1 is designed to lift the silo container 2 by a defined amount and subsequently continuously determine the weight of the silo container 2. Evaluation electronics 7 are used to record and process the measurement signals provided by the weight detection devices 1.
[0029] The Fig. 2 shows a section through a support leg 16 of the silo container 2 from Fig. 1 laterally mounted weight detection device 1 in a starting position, i.e. before weighing of the silo container 2 is possible. An essential component of this weight detection device 1 is a load cell 3, which in turn consists of a base body 4, on which a deformation section 6 is formed as a single piece. The deformation section 6 is deformed by the weight of the measuring object 2 acting on it, whereby an electrical output signal is generated in a measuring element 5 integrated in the deformation section 6, which electrical output signal is output in a Fig. 1, i.e., it can be converted into a value corresponding to the weight of the measuring object 2 and, if necessary, displayed. On the base body 4 of the load cell 3, Fig. In the example of the weight detection device 1 shown in Figure 2, there are also two connecting flanges 14 arranged at a distance from one another, which serve to fasten the weight detection device 1 to the support leg 16 of the measuring object 2. In this case, the connecting flanges 14 are each in the Fig. 2 unspecified threads are introduced, into each of which a corresponding screw bolt 24 is screwed, which is fixed to the support leg 16 of the measuring object 2, so that the weight detection device 1 can be fixed to the support leg 16 of the measuring object 2. Between the connecting flanges 14 and the deformation section 6 present between the connecting flanges 14, the load cell 3 in the present case has a deformation distance 15, which in the example shown is formed by a slot, so that the deformation section 6 can move into this deformation distance 15 due to the weight of the measuring object 2 acting on it and the measuring element 5 can generate a measurement signal proportional to the weight.
[0030] The assembly of the weight detection device 1 takes place in the Fig. 2 in such a way that first a ground anchor 21 is fixed in the substrate 9. The ground anchor 21 in this case is a screw bolt screwed into the substrate 9, which above the substrate 9 merges into a fastening eye into which another screw bolt 22 is screwed. With this type of fastening, the screw bolt 22 fixes a threaded bolt 13, onto whose thread a pressure sleeve 10 is screwed. The pressure sleeve 10 has a pressure flange 11 in the area of the deformation section 6 of the load cell 3, which pressure flange 11 slides against a corresponding annular flange 12 of the deformation section 6. By a relative movement between the pressure sleeve 10 and the threaded bolt 13, the pressure sleeve 10 and the threaded bolt 13 are moved into or apart from one another, thereby generating a lifting movement. The initiation of the relative movement of the pressure sleeve 10 in relation to the threaded bolt 13 takes place in the Fig. 2, via a hexagon nut 25 at the upper end of the pressure sleeve 10. The threaded bolt 13 and the pressure sleeve 10, in conjunction with the deformation section 6, form a lifting device 8, which is an essential component of the weight detection device 1 according to the invention. On the underside of the base body 4 of the load cell 3, there is also a cable connection 23, which in the present case enables the connection to the evaluation electronics 7.
[0031] If, as previously explained, a relative movement is realized between the pressure sleeve 10 and the threaded bolt 13, so that as a result of this relative movement the pressure sleeve 10 and the threaded bolt 13, viewed in the longitudinal direction, move apart, this generates a lifting movement of the lifting device 8, which leads to the lifting of the support leg 16 of the measuring object 2. Such a raised position of the support leg 16 is shown in the illustration of the Fig. 3. Due to the movement of the lifting device 8, the support leg 16 of the measuring object 2 has been raised in the direction of arrow A, so that a distance B exists between the substrate 9 and the underside of the support leg 16 of the measuring object 2. As a result, the weight of the measuring object 2 now permanently acts on the measuring element 5 and thus any change in the weight of the measuring object 3 can be recorded.
[0032] The Fig. 4 illustrates an alternative embodiment of a weight detection device 1 with a load cell 3. Here, too, the load cell 3 consists of a base body 4, on which the deformation section 6 and two connecting flanges 14, each spaced apart by a deformation distance 15 and running approximately parallel to one another, are integrally formed. As in the previously described example, a through-bore is made in each of the connecting flanges 14, the diameter of which is larger than the diameter of the threaded bolt 13, which was screwed into a corresponding thread of the deformation section 6. On its side facing away from the thread, the threaded bolt also has a hexagon nut 25, the contact surface of which rests on a base 26. The base 26 is designed as a ball joint in this case in order to be able to compensate for movements.By rotating the threaded bolt 13, a relative movement is generated between the thread in the deformation section 6 and the threaded bolt 13 screwed therein, which leads to a lifting movement of the lifting device 8. In this way, the measuring object 2 can be lifted in the direction of arrow A, so that the measuring object 2 has a distance B to the base 9 in the weighing position, as described in connection with the description of the . Fig. 3 has already been explained.
[0033] From the Fig. 5 shows a spatial representation of a supporting leg 16 of the measuring object 2, which in this case is the silo container from Fig. 1. The weight detection device 1 is attached laterally to the support leg 16 of the measurement object 2. Two connecting flanges 14, which are designed as webs here and each have a deformation distance 15 in the form of a slot to the deformation section 6 arranged centrally between the connecting flanges 14, serve to connect the weight detection device 1 to the support leg 16. The illustration also clearly shows how the ground anchor 21 can be attached to the substrate 9. The previously described screw bolt is passed through the visible hole in the ground anchor 21 and fixed in the substrate 9. The connection between the ground anchor 21 and the threaded bolt 13 is made via the screw bolt 22.
[0034] Only as an example, the Fig. 6 shows a section of an E-shaped load cell 3, which is attached to the side of the support leg 16 of the measuring object 2 via 4 holes in the connecting flanges 14. In the illustration of the Fig. 5 and Fig. 6, the remaining elements of the weight detection device 1 were omitted and only the load cell 3 was shown in order to illustrate the possibility of using different load cells 3 and their attachment to the measuring object 2.
[0035] In addition, the Fig. 7 shows a section of a T-shaped load cell 3 of a weight detection device 1 on a support leg 16 of a measuring object 2, which is the previously mentioned silo container.
