    [001] The present invention relates to pairs of cylinders, in particular pairs of grinding cylinders, measuring devices for insertion, in particular removable, in a receiving opening of a cylinder body of a cylinder of a pair of rollers, in particular of a grinding roller of a pair of grinding rollers, product processing facilities, which contain at least one pair of rollers, in particular, grinding facilities which contain at least one pair of rollers. milling, a method for operating a product processing plant, in particular a milling plant, as well as a method for the readjustment and/or preparation of a cylinder body of a pair of cylinders, in particular of a pair of grinding cylinders.
    [002] Grinding cylinders, as they are used, for example, in grain grinding, need constant supervision. Thus, it may occur, for example, that occasionally a so-called dry running occurs, in which adjacent grinding cylinders come into contact with one another and the engine's driving power is converted into uncontrolled heat. If this state lasts for a long time, then the grinding cylinder temperature can rise in a critical area and likely cause combustion.
    [003] To avoid this, it is already known to supervise the temperature of a grinding cylinder with the aid of one or more sensors and, when reaching a flammable temperature, issue an alert warning. For this purpose, optical systems for detecting the peripheral surface of the grinding cylinder are often mentioned. However, the problem with this is that this optical system is located in the product space through which the grain charge flows. For this reason, such optical systems are highly susceptible to dirt.
    [004] From document DE 102 26 411 A1 it is known to measure the temperature of the peripheral surface of the grinding cylinder with the aid of non-contact temperature sensors. Because of the distance between the sensor and the peripheral surface of the grinding cylinder, the actual temperature of the peripheral surface may deviate significantly from the measured temperature. These deviations then need to be considered by the assessment based on empirical values, which is circumstantial and error-prone. Also DE 198 19 614 AI discloses temperature probes which are arranged at a distance from the grinding rollers.
    [005] Equally important is the supervision of the wear of the cylinders. To that end, DE 42 22 085 AI discloses devices for measuring the nature of the surface of a grinding cylinder. These devices are, however, likewise arranged outside the peripheral surface of the grinding cylinder and therefore have the disadvantages already described above.
    [006] Likewise, a device and a method are known, with which wear can be measured by guide rollers. Measurement is possible, however, only in the idle state of the grinding cylinders. Even if this measurement is accurate, the milling installation must always be stopped for this.
    [007] Furthermore, sensors are known, with which the aid, the pressure between two adjacent grinding cylinders can be measured. Furthermore, from the patent document WO 2007/025395 AI, vibration sensors for grinding cylinders are known, for example. All these sensors are likewise arranged outside the grinding cylinders.
    [008] It is an objective of the present invention to overcome the known disadvantages of the prior art. In particular, a pair of rollers, in particular a pair of grinding rollers and a product processing plant, in particular a grinding plant, are provided for grinding grain loads, with which, a state of at least a cylinder or both cylinders of a pair of cylinders, in particular of at least one grinding cylinder or both grinding cylinders of a cylinder of a pair of grinding cylinders, can be measured more accurately and, in addition, be less subject to dirt. Thereby, at least in some embodiments, the operating safety must be high and conclusions about the performance of a procedure process, in particular, of a milling process, must be able to be provided.
    [009] This objective is solved, on the one hand, through a pair of cylinders for the processing of a product, which contains two cylinders, and at least one of the cylinders, in particular, both cylinders, contain or contain hair. minus one sensor. In particular, it can be a pair of grinding cylinders which contain two grinding cylinders, at least one of the grinding cylinders, in particular both grinding cylinders, containing or containing at least one sensor.
    [0010] Based on the state of the art, the person skilled in the art is led to arrange sensors only on the outside of a cylinder of a pair of cylinders that processes bulk load or mass and to perform experiments without considering at least once in determining if, in fact, contrary to all expectations implicit in the prior art, it would be possible to obtain functionality with sensors inside the peripheral surface of the cylinder. A person skilled in the art would not consider all possible experiments with a cylinder of a pair of cylinders that handles a bulk charge or mass that contains a sensor in part due to the relationships of force, pressure, temperature, and dirt around a pair of cylinders that processes bulk or bulk cargo and the conventional method methodology in bulk cargo processing. In order to actually achieve the idea of invention, serious, real /and/or apparent technical obstacles and/or disadvantages also need to be overcome by the inventor.
    [0011] Under "product" is understood, in the sense of the present invention, a bulk cargo or a mass. Under "bulk load" is understood, in the sense of the present invention, a product in powder, granules or in the form of pellets, which finds use in the industry that processes materials in bulk, that is, in the processing of grains, milling products of grain and grain end products from milling (in particular, milling of wheat, hard grains, rye, corn and/or barley) or special milling (in particular, soy husks or milling, buckwheat, barley, spelled, maize / sorghum, pseudocereals and/or legumes), in the production of feed for livestock, domestic animals, fish and shellfish, in the processing of oilseeds, in the processing of biomass and in the production of energy pellets, industrial malting and crushing facilities; in the processing of cocoa seeds, nuts and coffee seeds, in the production of fertilizers, in the pharmaceutical or chemical industry of solid matter.
    [0012] Under "dough" is understood, in the sense of the present invention, a pasta, such as a chocolate mass or a sugar mass or a colorant, a coating, an electronic material or chemicals, in particular refined chemicals.
    [0013] Under "processing a product" is understood, in the sense of the present invention, the following:
    [0014] - the grinding, fragmenting and/or forming of bulk cargo flakes, in particular, grains, grain mill products and final grain products from special milling or milling as performed above, for which the pairs of cylinders milling or flake-forming rollers, described in more detail below, for example as roller pairs, may be used.
    [0015] - the refining of pasta, in particular of pasta such as chocolate pasta or sugar pasta, for which pairs of refining cylinders, for example, can be used;
    [0016] - the wet grinding and/or dispersion, in particular, of dyes, coatings, electronic materials or chemicals, in particular, refined chemicals.
    [0017] The grinding cylinders, in the sense of the present invention, are arranged to grind a grain load, which is normally conducted between one of the grinding cylinders of the pair of grinding cylinders. Grinding rollers, in particular the grinding rollers of the grinding roller pairs according to the invention, provide - generally, by an essentially inelastic surface (in particular on its peripheral surface), which can, for this purpose , contain metal or consist of it, such as steel - in particular stainless steel. Between the grinding rollers of the grinding roller pairs there is, in general, a relatively fixed and often hydraulically regulated grinding gap. In many milling plants, the grain load is conducted essentially vertically downwards through such a milling slit. In addition, the grain load is conveyed, in many milling plants, to the milling cylinders of a pair of milling cylinders by means of its gravity, which conduction can optionally be supported pneumatically. The grain charge is usually granular and moves as a fluid flow through the grinding slit. By these features, a grinding cylinder (in particular a grinding cylinder from a pair of grinding cylinders) and a grinding installation, for example, of several cylinders, which contain at least one such grinding cylinder, are differentiated. , is generally used for transporting paper.
    [0018] At least one cylinder, in particular, both cylinders of the pair of grinding cylinders, in particular, at least one grinding cylinder, in particular, both grinding cylinders of the pair of grinding cylinders, can or can, by eg be or be formed as a flat cylinder or as a corrugated cylinder or as cylinder base bodies with bolted plates. Flat cylinders can be cylindrical or arcuate. Corrugated cylinders can have wavy geometries, such as corrugated tile or trapezoid geometries and/or have segments arranged on the peripheral surface. At least one roller, in particular both rollers of the pair of grinding rollers, in particular at least one grinding roller, in particular both grinding rollers of the pair of grinding rollers, may or may have a length in the range from 500 mm to 2000 mm and a diameter in the range from 250 mm to 300 mm.
    [0019] The peripheral surface of the cylinder, in particular the grinding cylinder, is connected to the cylinder body preferably non-removably and in particular thus forms with it a single piece. This allows for simple production and processing, in particular safe and robust grinding of the product.
    [0020] The at least one sensor is formed for recording measurement values, which characterize a state of at least one of the cylinders, in particular, of both cylinders of the pair of cylinders. In particular, this can be a condition of a peripheral surface of at least one of the cylinders, in particular of both cylinders of the pair of cylinders. The state can be, for example, a temperature, a pressure, a force (component(s) of force in one or more directions), a wear, a vibration, a deformation (dilation and/or displacement), a speed of rotation , a torsional acceleration, an ambient humidity, a position or an orientation of at least one of the cylinders, in particular of both cylinders of the pair of cylinders.
    [0021] Unlike the prior art known above, at least one cylinder of the pair of cylinders, in particular, at least one grinding cylinder of the pair of grinding cylinders contains at least one sensor. When the cylinder rotates, in operation, then the sensor also rotates. In particular, the at least one sensor is arranged within a peripheral surface of the cylinder. Therefore, the at least one sensor is not located in the product space, through which also the product, in particular the grain load, flows. A product processing plant with at least one such cylinder, in particular a grinding plant with at least one such grinding cylinder, is therefore less subject to dirt. Furthermore, the measurement can take place directly on the cylinder, which makes the measurement significantly more accurate.
    [0022] The sensor can be formed, for example, as sensorMEMS (MEMS: Micro-Electro-Mechanical System/ micro-electrical-mechanical system).
    [0023] Preferably, the sensor remains in data connection with at least one data transmitter, the data transmitter being formed for contactless transmission of the measured values of at least one of the sensors in a data receiver.
    [0024] The measured values can be transmitted contactless with the aid of at least one data transmitter to a data receiver which is not a component of the cylinder. In particular, it can be a stationary data receiver, against which the at least one sensor is moved by rotation of the cylinder. Through the non-contact transmission, it is possible to avoid the use of expensive cable swivel joints that would otherwise be necessary.
    [0025] Even more preferably, the data sender is arranged on or on the same cylinder as the sensor which remains in data connection.
    [0026] Advantageously, the at least one cylinder, in particular both cylinders, contains several sensors as described above, in particular, at least two, particularly, at least four, even more particularly, at least six sensors, which are contained in the cylinder. Even more particularly, several sensors remain in data connection with the at least one data transmitter. Sensors can be arranged at different positions along an axis of rotation of the cylinder and/or at different angles around that axis of rotation. The more sensors the cylinder contains and the more evenly they are separated, the more significant the measurement values recorded internally. Preferably, the sensors are uniformly arranged in a peripheral direction, whereby a rotational balance takes place.
    [0027] At least one sensor can be formed as
    [0028] - temperature sensor, particularly, several temperature sensors are available, which are arranged along an axis of rotation of the cylinder, to be able to determine a temperature profile along that direction;
    [0029] - pressure sensor;
    [0030] - force sensor (for determining the force components in one or several directions);
    [0031] - wear sensor;
    [0032] - vibration sensor, in particular, to determine a condensation, that is, an adhesion of the processed products on the peripheral surface of the cylinder, which impairs the processing, in particular, the grinding in that position;
    [0033] - strain sensor (to determine an expansion and/or a strain);
    [0034] - rotation speed sensor, in particular to determine a cylinder's idle time;
    [0035] - Torsional acceleration sensor;
    [0036] - sensor to determine an ambient humidity that is particularly disposed on a front side of the cylinder;
    [0037] - gyroscopic sensor to determine the position and/or orientation of the cylinder, in particular, to determine the width that depends on the position and/or orientation of a gap between the two cylinders of the pair of cylinders as well as the parallelism of the cylinders ;
    [0038] - sensor for determining the width of a gap between the two cylinders of the pair of cylinders, in particular of a grinding gap between the two grinding cylinders of the pair of grinding cylinders, for example, a sensor arranged on the front side cylinder, in particular, a MEMS sensor.
    [0039] Evidently, any combination of them is possible. For example, the cylinder can contain multiple temperature sensors and strain sensors. Furthermore, it is possible and within the scope of the invention for all sensors to be of the same type, that is, for example, to be formed as temperature sensors. It is, however, likewise possible within the scope of the invention that at least one cylinder, in particular both cylinders, contains or contains different types of sensors.
    [0040] Under wear is, in this case, here and later understood, the mechanical wear of the peripheral surface of the cylinder, in particular of the grinding cylinder. Such wear can, for example, be determined by a change in strength, which occurs through a wear of the material on the peripheral surface. Alternatively or complementary, wear can be determined by a modified pressure and/or a modified optical path and/or a modified electrical capacity.
    [0041] If one or both cylinders contain or contain both several sensors as well as at least one data emitter, then it is preferable that the at least one data emitter for the contactless transmission of the measurement values is formed by several sensors, more particularly, by all sensors, in a data receiver. Preferably, at least one cylinder, in particular both cylinders, respectively, at most only a single one, especially preferably a single data transmitter, for the contactless transmission of the measured values. The fewer data emitters the cylinder contains, the simpler it is to assemble that cylinder.
    [0042] In particular, if at least one cylinder contains only one data sender, then it contains that cylinder, in particular both cylinders, particularly at least one multiplexer, which is arranged and formed for the alternate transmission of values recorded by the sensors in the data sender.
    [0043] Contactless transmission can occur, for example, through infrared radiation, through light pulses, through radio frequency signals, through inductive coupling or through any combination thereof.
    [0044] The non-contact transmission of measured values here also and always subsequently involves the transmission of data, which are obtained by corresponding processing of the measured values and thus depend on the measured values. For example, at least one cylinder, in particular both cylinders, can contain at least one signal converter, in particular at least one A/D converter, for the conversion of measured values recorded by at least one sensor. In a first possible variant, each sensor can be assigned at least one signal converter which converts the measured values recorded by that sensor. Finally, the converted signals can be fed to a multiplexer as already described above. If the signal converter is an A/D converter, then the multiplexer can be a digital multiplexer. In the second possible variant, the signal converter can also be arranged between a multiplexer as described above and the data transmitter. In this case, the multiplexer can be an analog multiplexer.
    [0045] Preferably, at least one cylinder, in particular both cylinders, in particular a cylinder body - described below, below - of a cylinder, in particular both cylinders, contains at least one energy receiver and/ or at least one power generator. Thereby, a power supply of the at least one sensor and/or at least one multiplexer (in particular, at least one multiplexer as described above) and/or at least one signal converter (in particular, at least one of a signal converter as described above) and/or the at least one data emitter (in particular the data emitter contained in or within the cylinder) and/or at least one data emitter of another measuring device described below , then can be obtained. In particular, it may be an inductive energy receiver. In this variant, the energy receiver can have, for example, at least one receiving coil, with the help of which electromagnetic energy can be coupled inductively. Alternatively or complementary, the energy receiver can, however, be formed to receive energy from light. Alternatively or complementary, it is also possible, however, and it is within the scope of the invention, that at least one selection cylinder, in particular both cylinders, contains or contains at least one battery, in particular rechargeable, with whose help, the so-called power supply, can be obtained.
    [0046] In a variant, the power generator can be formed to obtain energy from the movement of the cylinder. The energy generator can, for example, be formed to obtain energy from the
    [0047] - thermal difference within the cylinder, in particular, under the use of thermoelectric effects, such as the Seebeck, Peltier or Thomson effect, with the aid, for example, of a thermoelement, and/or
    [0048] - vibrations of the cylinder, with the aid, for example, of at least one piezoelectric element and/or mechanical element and/or
    [0049] - the rotation of the cylinder, with the aid, for example, of at least one piezoelectric element and/or mechanical element.
    [0050] Advantageously, the cylinder may contain both at least one energy receiver and/or at least one energy generator and at least one rechargeable battery that is rechargeable by the energy receiver and/or energy generator.
    [0051] Advantageously, at least one cylinder, in particular both cylinders, contains at least one printed circuit board (in particular a printed circuit board MEMS), on which the at least one sensor and/or at least a multiplexer (in particular, at least one multiplexer as described above) and/or at least one signal converter (in particular, at least one signal converter as described above) and/or the at least one data sender (in particular the data sender contained in or within the cylinder) and/or at least one energy receiver (in particular, at least one energy receiver as described above) and/or at least one energy generator (in particular, at least one power generator as described above). The printed circuit board may contain measurement leads through which sensors are connected to the multiplexer. Such a printed circuit board has the advantage that the components named here can be arranged very compactly and that the circuit board can be produced as a separate assembly and can be exchanged again if necessary, at least in some examples of modality.
    [0052] As an alternative to the printed circuit board, the sensors can, however, also be connected to the data transmitter and/or the multiplexer by a bundle of cables.
    [0053] In various embodiments, at least one cylinder, in particular both cylinders, comprises a cylinder body with at least one receiving opening, as well as at least one measuring device, which can be inserted or is inserted, in particular, detachably, in the reception opening. The peripheral surface of the cylinder body forms at least a part of the peripheral surface of the cylinder, in particular the entire peripheral surface of the cylinder. The measuring device contains at least one of the cylinder's sensors. Furthermore, it may contain at least one multiplexer (in particular, at least one multiplexer as described above) and/or at least one signal converter (in particular, at least one signal converter as described above). This assembly of at least two parts of the cylinder likewise allows the production of separate sets. In particular, when the measuring device is detachably inserted in the reception opening, it can be easily exchanged if it needs cleaning or maintenance or if it is defective.
    [0054] In other embodiments, it may also be useful, however, if the measuring device is non-removably inserted into the receiving opening. In this way, the measuring device can be more securely connected to the cylinder body. Additionally, unauthorized device removal can be avoided, which could impair safety. The measuring device can be poured (eg with the aid of a resin) or welded into the receiving opening. By this, also the risk of explosions can be avoided, so that, in particular, the ATEX requirement of the European Union can be fulfilled.
    [0055] The reception opening can be formed, in some embodiments, essentially through cylindrical holes, which can have a diameter in the area of 5 mm to 40 mm, preferably from 5 to 25 mm, in a special way. from 10mm to 14mm is preferred. This hole can extend essentially parallel to the axis of rotation of the cylinder body. In order to determine the state of a peripheral surface, the receiving opening is arranged particularly in an external area of the cylinder body. Thus, the reception opening can be found, for example, in a cylindrical area of the cylinder body.
    [0056] In advantageous embodiments, the receiving opening extends essentially along the entire length of the cylinder body, in the direction of the axis of rotation, i.e. along at least 50%, particularly at least 70%, more particularly at least 90% of the total length of the cylinder body. In this way also the state of the cylinder essentially along its length can be determined. Preferably, the at least one receiving opening is arranged in such a way that a balance of the masses is considered, since thereby a balancing of the cylinders can be dispensed with. Alternatively, also two or more reception openings can be available, which are arranged, particularly uniformly, in the peripheral direction; hereby also, a balancing can be dispensed with.
    [0057] The measuring device can be formed in bar shape and have a longitudinal axis, along which several sensors, for example temperature sensors, are arranged.
    [0058] In other embodiments, the receiving opening may be formed on a peripheral surface of the cylinder body. In particular, it can extend essentially in the radial direction of the cylinder body, that is, essentially vertical to an axis of rotation of the cylinder body. If a measuring device is inserted into such a receiving opening, a state of the peripheral surface of the cylinder can be measured in a particularly simple way, for example a dominant temperature on a peripheral surface.
    [0059] Preferably, the cylinder body can contain at least both one radial receiving opening, which is formed on a peripheral surface of the cylinder body and in which at least one of the sensors is disposed, and at least one receiving opening which then runs parallel to the axis of rotation on which the printed circuit board is disposed. The sensors can either be connected to the printed circuit board or be formed and arranged in relation to the printed circuit board in such a way that they can communicate without contact, for example, through ultrasound, infrared radiation, inductive coupling, signals of radio frequency or a combination thereof.
    [0060] The measuring device can be designed as a pin with a thread and the receiving opening can have a counter-thread into which the thread of the pin can be screwed. Alternatively or complementary, the measuring device can be formed as a pin with a first bayonet-like closure element and the receiving opening can have a second bayonet closure element in which the first bayonet closure element of the pin can be inserted. The first and/or the second bayonet-type closure element may have a shield. Both variants allow simple insertion and, if necessary, simple removal of the measuring device from the reception opening.
    [0061] This embodiment as a pin is therefore particularly suitable if the pin has a sensor formed as a wear sensor, as a pressure sensor or as a temperature sensor.
    [0062] Particularly preferably, the measuring device, in particular the pin, has at least one other data transmitter and at least one other data receiver. In that case, the data sender of the measuring device and the data receiver are formed and arranged in such a way that the measurement data recorded by the sensor can be transmitted contactless from at least one other data sender to at least one other receiver of data. This has, in particular, the advantage that if the measuring device can only be releasably inserted into the receiving opening, on insertion no cable connections are required, in particular no connections are required between the measuring device. measurement and cylinder body.
    [0063] Contactless transmission from another data transmitter to another data receiver can take place, in particular, through an internal space of the cylinder body, in particular, through a cavity in the cylinder body. A transmission through a cavity is less prone to interference and also requires only a comparatively low transmission energy. Contactless transmission from other data transmitters to other data receivers can take place, for example, through infrared radiation, through light pulses , through radio frequency signals, through inductive coupling or through any combination thereof.
    [0064] The measuring device, in particular the pin, can be supplied with energy inductively and/or by light. Alternatively or complementary, the metering device, in particular the pin, may contain an energy receiver as described above and/or an energy generator as described above, which is formed to obtain energy from the movement of the cylinder. , for example, from the
    [0065] - thermal difference within the cylinder, in particular, under the use of thermoelectric effects, such as, for example, the Seebeck, Peltier or Thomson effect, with the aid, for example, of a thermoelement, and/or
    [0066] - vibrations of the cylinder, with the aid, for example, of at least one piezoelectric element and/or mechanical element and/or
    [0067] - the rotation of the cylinder, with the aid, for example, of at least one piezoelectric element and/or mechanical element.
    [0068] Likewise, alternatively or complementary, the measuring device, in particular the pin, can have at least one battery, in particular rechargeable.
    [0069] As an alternative or complementary to a data receiver integrated in the cylinder body, a product processing plant containing the pair of cylinders, in particular a grinding plant containing the pair of grinding cylinders, may also have a data receiver that is arranged outside the cylinder. Such a data receiver can be formed in the form of a bar and extend, in particular, vertically to an axis of rotation of the cylinder.
    [0070] If several reception openings are available, then they may be arranged at different positions along the axis of rotation of the cylinder body and/or at different angles around that axis of rotation. The more evenly the reception openings are distributed, the more significant are the measurement values recorded by the measuring devices inserted into these reception openings. Preferably, the receiving openings are uniformly arranged in the peripheral direction, whereby the balancing of rotation takes place, it being possible to dispense with a necessary balancing otherwise necessary.
    [0071] The at least one data sender (in particular, the at least one data sender from one or both cylinders or the data sender mentioned above) and/or the data receiver (in particular, the data receiver of the cylinder body of these cylinder(s) and/or the energy receiver and/or the energy generator are particularly arranged on a front side of such cylinder(s), in particular on a front side of a cylinder body of that cylinder(s). On such a front side, the non-contact transmission of the measured values does not suffer any or practically any interference by the product ground with the cylinder.
    [0072] A printed circuit board as described above may be in a component of the measuring device of the form of realization. The at least one sensor and/or at least one multiplexor (in particular, at least one multiplexor as described above) and/or at least one signal emitter (in particular, at least one signal emitter as described above) can be arranged in that measuring device.
    [0073] The cylinder can contain at least one data store, in particular, an RFID chip. In such a data store, for example, a particularly individual identification of the cylinder can be or be stored. Alternatively or complementary, at least one characteristic of the cylinder can be or be stored in the data store, such as at least one of its dimensions or pumping. The data saved in the data store are transmitted, in particular, in the same way, without contact. For this purpose, the cylinder may have a data emitter. In this case, it is possible for the data from the data store to be transmitted via the same data transmitter, with which, according to the invention, the measured values of at least one sensor are transmitted.
    [0074] Another aspect of the invention relates to a measuring device for inserting, in particular, removable in a receiving opening of a cylinder body of a cylinder of a pair of cylinders. In particular, the receiving opening can be formed on a peripheral surface of the cylinder body. By cylinder it can be a grinding cylinder of a pair of grinding cylinders as described above and by cylinder body it can be a cylinder body of such a grinding cylinder.
    [0075] According to the invention, the measuring device has at least one sensor for recording measurement values that characterize a state of the cylinder, in particular a state of a peripheral surface of the cylinder. Furthermore, the measuring device according to the invention can have at least one data transmitter for transmitting, in particular, contactless measurement values to a data receiver. Data can be transmitted, in a first variant, on a stationary data receiver, as described above. In a second variant, data can also be transmitted, however, on a data receiver as described above, in particular on another data receiver as described above or on a data receiver of the cylinder body.
    [0076] The measuring device can also contain a data processor integrated to it, in particular, a microprocessor, an FPGA, a PLC processor or a RISC processor. This data processor can, for example, continuously process the measurement values recorded by at least one sensor and then optionally transmit them to the data sender, in particular if this is contained in the cylinder. In particular, the data processor can fully or partially assume the function of the multiplexor described above and/or the signal converter. The microprocessor can be a component of the printed circuit board described above. The microprocessor can also alternatively assume or complement the following functions: Communicate with at least one data bus system (in particular IP address management); circuit board storage management; control of power management systems as described above; management and/or storage of identification characteristics of the cylinder(s), such as geometric data and cylinder history; interface protocol management; wireless functionality.
    [0077] In addition, the measuring device, in particular, the printed circuit board can provide, by an energy management system, which can perform one, several or all of the following functions:
    [0078] - regular transmission, in particular periodic transmission of measurement values from the data emitter;
    [0079] - transmission of measurement values from the data emitter only under a predetermined condition, in particular, by filling out another alert criterion described below;
    [0080] - regular charging and discharging, in particular, periodic of a capacitor or energy store.
    [0081] The product processing plant for processing a product, in particular the milling plant for grinding grain load, contains at least one pair of cylinders as described above, in particular a pair of grinding cylinders. A gap is formed between the pair of cylinders. In particular, a grinding gap is formed between the grinding rollers and a pair of grinding rollers.

    [0082] In some embodiments, in particular, by refining doughs, such as chocolate doughs or sugar doughs, these doughs can alternatively also be guided from the bottom upwards through the gap formed between the cylinders.

    [0099] - contain at least one sensor for determining the width of a gap between the two cylinders of the pair of cylinders, in particular of a grinding gap between the two grinding cylinders of the pair of grinding cylinders, for example a sensor arranged on the front side of the cylinder, in particular, a MEMS sensor.
    [00100] The measuring device can contain on or on the external side at least one end opening of the receiving opening, at least one data transmitter for the particularly non-contact transmission of the measurement values in a data receiver.
    [00101] Yet another aspect of the invention relates to a product processing plant, in particular, a milling plant for milling the grain load. The product processing plant according to the invention contains at least pair of cylinders as described above. In addition, the product processing installation can have at least one data receiver, in particular stationary, for receiving the measurement values transmitted by the data transmitter from at least one of the cylinders, in particular from both cylinders, of the pair of cylinders. . With such a product processing facility, the advantages mentioned above can be obtained. In particular, if the milling plant contains several different pairs of cylinders, to which the product is led from the same product inlet, it may be advantageous to form only one pair of cylinders according to the invention.
    [00102] A milling plant can be, for example, an individual cylinder mill of a grain mill or also a complete grain mill with at least one cylinder mill, with at least one cylinder mill containing at least one grinding cylinder as described above. The product processing facility, however, can also be:
    [00103] - a rolling mill for forming bulk flakes, in particular, grains, grain mill products and final grain products from milling or special milling, as performed above;
    [00104] - a roller mill or a mill for the production of chocolate, in particular a premill with, for example, two or five rollers, in particular two or five refining rollers, or a refining or finishing mill ;
    [00105] - a laminator for wet grinding and/or dispersing, for example, dyes, coatings, electronic materials or chemicals, in particular refined chemicals, in particular a triple laminator.
    [00106] Another aspect of the invention is directed to a method for operating a product processing plant as described above, in particular, a milling plant as described above. The method comprises a step, in which, with the data receiver of the product processing installation, the measurement values transmitted by a data transmitter from at least one of the cylinders, in particular from both cylinders, of the pair of cylinders can be received.
    [00107] Data received in this way can ultimately be evaluated and continuously processed. For this purpose, they can be led to a control unit of the product processing plant, in particular the milling plant, from where they can be forwarded to another superior control system. As an aid to the control unit and/or the control system, the entire product processing facility, in particular the entire milling facility or a part thereof, can be controlled and/or regulated.
    [00108] In particular, an alert message can be sent by the control unit, if any alert criteria is fulfilled. The alert criterion can consist, for example, that the measured value of at least one of the sensors exceeds a previously defined threshold value for that sensor. In another variant, the alert criterion can consist in that the difference between the largest measurement value and the smallest measurement value, which are measured by a predefined number of sensors, exceeds a predefined threshold value.
    [00109] If the alert criterion is fulfilled, then an alert signal can be issued (for example, optical or acoustic) and/or the product processing facility can be brought to the inactive state (for example, through the control unit). Furthermore, the control unit can visualize the measurement values registered by at least one of the sensors or data obtained by it.
    [00110] The product processing facility may contain downstream of the product of the pair of cylinders according to the invention, at least one device for measuring the size of particles and their distribution. Thereby, the measurement of particle size and their distribution can be combined, for example, with a measurement of the wear state and/or cylinder pressure. This is, in particular, of great advantage if the cylinder, in particular the grinding cylinder, is a corrugated cylinder. Alternatively or complementary, downstream of the product of the pair of cylinders according to the invention, in particular of the grinding cylinder, according to the invention, there is also a device for measuring NIR of the flow of the product, in particular of the grain flow, can be arranged. This is of particular advantage in the case of rollers, in particular grinding rollers, flat rollers. Both variants make it possible, due to the recognition of the state of wear, to plan maintenance in advance.
    [00111] Yet another aspect of the invention relates to a method for readjusting and/or preparing at least one cylinder body, in particular both cylinder bodies of a pair of cylinders for processing a product, with at least a receiving opening for the metering device, in particular of a cylinder body as described above. In particular, the cylinder body of the cylinder body can be a grinding cylinder. The method includes a step, in which a metering device, in particular a metering device as described above, is inserted into the receiving opening so that a pair of cylinders as described above is received.
    [00112] In the following, the invention is explained in more detail based on the drawings and embodiment examples. In this case, show
    [00113] Figure 1: a schematic representation of a first grinding installation with a grinding cylinder and several temperature sensors;
    [00114] Figure 2: another schematic representation of the milling installation according to Figure 1:
    [00115] Figures 3a to d: four photos with detailed views of a measuring device contained in the grinding cylinder according to Figure 1;
    [00116] Figure 4: a second example of embodiment according to the invention of a grinding installation with a grinding cylinder with several pressure sensors.
    [00117] Figure 1 shows a first product processing plant, which is formed as milling plant 18 for grain loading milling, in particular, for grain milling. The grinding installation 18 contains a pair of grinding cylinders from a first grinding cylinder 1 with seven temperature sensors 2 and a data transmitter 4, as well as a second grinding cylinder 19, which need not necessarily contain , a sensor or a data emitter. The first grinding cylinder 1 contains a cylinder body 10 with a receiving opening 11 in the form of a cylindrical hole, which extends parallel to an axis of rotation A of the cylinder body 10 and along the entire length thereof. In the receiving opening 11, a bar-shaped measuring device 12 is inserted which contains the seven temperature sensors 2. The measuring device 12 is poured into the receiving opening 11 and thereby non-removably inserted. in the receiving opening 11. With the aid of the temperature sensors 2, measurement values can be recorded which characterize the temperature at different positions of a peripheral surface 3 of the grinding cylinder 1. The assembly of the measuring device 12 is described below, in more detail below, with reference to Figures 2 and 3a to 3d.
    [00118] On a front side 20, the grinding cylinder 1 presents, by the rotary operation with rotary data transmitter 4 for the non-contact transmission of the measured values of the temperature sensors 2 to a data receiver 5. The non-contact transmission of measurement values can occur through infrared radiation, through light pulses, through radio frequency signals, through inductive coupling or through any combination of these. The grinding cylinder 1 also has on its front side 20 an inductive energy receiver 9, through which the energy of an inductive magnet 21 can be coupled.
    [00119] By the conductor 22, the data received by the data receiver 5 are led to a control unit 23, with whose assistance, the total milling length or a part thereof can be controlled and/or regulated. The control unit 23 contains display means 24, for example a screen, by means of which the measurement values recorded by the temperature sensors 2 or data obtained therefrom can be displayed. Furthermore, the control unit 23 can issue an alert message if a predetermined alert criterion is met, eg if the temperature measured from one of the temperature sensors 2 exceeds a predefined threshold value. By another conductor 25, data can be routed in an optional overhead control system.
    [00120] In the lower part of Figure 1, the progress of the temperature is shown schematically, as it could be represented with the display means 24 of the control unit 23. If, for example, a dry operation occurs in the position 27 of grinding cylinder 1, then the local temperature increases in this area, which may be an indication of possible combustion. Due to the plurality of temperature sensors 2, position 27 can be precisely located, allowing countermeasures to be found.
    [00121] In Figure 2 it is schematically represented again how the measurement values are transmitted from the seven temperature sensors 2 in the control unit 23. The measuring device 12 contains a printed circuit board 8, on the which the seven temperature sensors 2 and a multiplexer 6 are arranged. In this case, each of the temperature sensors 2 is connected to the multiplexer 6 by respectively two measuring conductors. The multiplexer 6 alternately transmits the measurement values recorded by the temperature sensors 2 over a cable 29 to the data transmitter 4, which then transmits the measurement values, without contact, to the data receiver 5.
    [00122] Figures 3a to 3d show several detailed views of the measuring device 12. In Figure 3a it is possible to recognize the printed circuit board 8 with the multiplexor 6.
    [00123] In Figure 3b it is possible to see one end of the measuring device 12 from which the cable 29 exits. At the end of this cable 29 there is a connector 30, with which the measuring device 12 can be connected to the data transmitter 4.
    [00124] Figure 3c contains another view in detail of the end of the measuring device 12 that can be recognized, already shown in Figure 3b.
    [00125] Figure 3d shows a rear view of part of the measuring device 12 shown in Figure 3c, in which it is possible to recognize one of the temperature sensors 2. The temperature sensors 2 can be, for example, of the known type PT 1000 .
    [00126] In Figure 4 a second embodiment of a product processing plant according to the invention is schematically reproduced, which can likewise be formed as a milling plant 18' for grain loading milling , in particular, grains. For simplification of the representation, only one grinding cylinder 1' of a pair of cylinders is reproduced here and not another grinding cylinder 19 as in Figure 1. On a peripheral surface 3' of a cylinder body 10' of the cylinder of milling 1' several receiving openings 11' are available of which only 3 are shown here. These receiving openings 11' extend radially from the cylinder body 10', i.e. vertical to an axis of rotation A' of the cylinder body 10'.
    [00127] In Figure 4 is also shown a 12’ pin (not scaled) of a measuring device. This 12’ pin contains a thread not shown in the Figure. Each of the receiving openings 11' has a counter-thread, likewise not shown, into which the pins 12 can be screwed. Pin 12’ also features a sensor, as well as a data emitter, both of which are not represented in Figure 4. The sensor can be, for example, a wear sensor, a pressure sensor or a temperature sensor.
    [00128] On a front side 20’ of the grinding cylinder 1’ there are arranged a data transmitter 4’, a power receiver 9’ and a data receiver 16’. The measurement data recorded by the sensor 2' can thus be transmitted contactless by the data sender of the pin 12' to the data receiver 16' of the cylinder body 1', for example, via infrared radiation, via pulses of light, through radio frequency signals, through inductive coupling, or through any combination thereof. This takes place particularly through an internal space, in particular a cavity of the cylinder body 10'.
    [00129] The 12' pin can be powered inductively and/or by light. Alternatively or complementary, it can contain at least piezoelectric element, by means of which force existing by the rotation of the grinding cylinder 1', electrical energy can be generated. Likewise, as an alternative or complementary form, the pin 12' can have at least one battery, in particular rechargeable.
