Definitions
- the invention relates to a system for changing a roller.
- Roller changing systems today are required to replace rollers in a short time if they no longer meet the requirements placed on them. Particularly in rolling mills, the need for roll changes is high.
- the object of the present invention is to provide a system with which the process reliability in rolling processes is increased.
- a system for changing a roll having a system for determining parameters which characterize the identity and / or the operating state of a roll of an industrial plant, having at least one sensor for storing parameters arranged on a roll, which is designed in such a way that in that a deposited identity parameter of the roller can be detected, and with a read-out device which is designed for contactless reading out of acquired parameters from the sensor, wherein the sensor also detects an operating state parameter of the roller is configured, and at a roller temperature of at least 150 0 C is operable with a roll change carriage, on which an insertable into a roll stand or executable from the rolling stand roll is storable, wherein the sensor for depositing and / or detection of parameters arranged on the roller is.
- the reading of identity parameters makes it possible to uniquely identify rollers at any time, as well as to unambiguously determine their characteristics based on the identified identity.
- the properties of a roller can be deposited directly in the sensor arranged on the roller.
- the property of a roll can be determined by means of a database into which specific rolls are each assigned specific properties.
- identification parameters are understood to mean all information or data which are specifically stored on a sensor in order to be able to read them later by means of a read-out device.
- the identification parameters include all stored data, which allow a unique identification of the roller on which the sensor is arranged.
- the identification parameters can be, for example, historical data of the roller, eg production date of the roller, manufacturer of the roller, intended fields of use and / or service life of the roller.
- operating parameters for example the tolerance range of physical variables such as temperature, pressure, etc., are also to be regarded as the identification parameters for the roller.
- Identification parameters can be set, ie can be variably stored in the sensor, or set, ie fixed and fixed once in the sensor.
- Operating state parameters are characterized by the fact that they reflect or mark the current operating state of a roller.
- An operating state is not stored in the sensor, but is first detected by the sensor, for example, by measurement or otherwise, such as calculation.
- the detection of operating condition parameters is also possible under adverse conditions, such as high temperatures, such as encountered in industrial plants.
- adverse conditions do not cause the roll changing system to be prone to error. Rather, the roll change system is designed so robust that it works even under these adverse conditions.
- adverse conditions are particularly found in metalworking industries such as steel mills or rolling mills.
- the sensor is preferably designed such that it is permanently operable in a temperature range of 150 0 C to 350 0 C and 200 ° C to 350 0 C.
- the sensor when the sensor is designed such that it is permanently operable in a temperature range of 150 0 C to 1000 0 C is particularly advantageous.
- a permanent operation of conventional RFID sensors is not possible in this temperature range today.
- the rolls provided with the sensor are to be exchanged frequently, for example because of wear, since under such circumstances the advantages of the invention become particularly prominent.
- the identity of the roller by means of the sensor is clearly and easily determined.
- operating state parameters can be detected particularly easily by the present invention during operation of the roller. This makes it possible to establish relationships between the behavior of the roller during operation, such as wear, and the operating state parameters. This can be used to improve or optimize the roll operation.
- Industrial equipment is understood to mean any equipment intended for industrial production or industrial service. These may include industrial laundries, steel and rolling mills, chemical industrial plants, industrial plants of the basic industry, in particular industrial plants for the production of paper, or any other industrial facilities.
- the readout device for contactless readout of the sensor may be mobile or stationary.
- the read-out device can be designed as a mobile hand-held device. This is particularly advantageous when e.g. Sensors on rollers in a roll grinding or roller bearings to be read by staff.
- the read-out device can be arranged on rollers of the industrial installation such that the sensor can be read out without contact.
- the read-out device can be arranged to be movable relative to the sensor.
- the read-out device is arranged on the roll changing carriage. Since the rolls are usually placed on the roll change carriage when changing rolls, a particularly fold an identification of the rollers done. Due to the arrangement of the read-out device on the roll change carriage, the read-out device can also be arranged protected if necessary. Furthermore, no additional mobile readout devices are required, which reduces the space requirement.
- the roll changing carriage comprises a gripper carriage, on which the read-out device is arranged.
- the gripper carriage is used for introducing the roller into the rolling stand or for carrying out the roller from the rolling stand.
- Run the gripper carriage is positioned relatively close to the roller. Therefore, by means of a read-out device arranged on the clamp carriage, the sensor can be read out easily and without errors. Therefore, in particular in the arrangement of the read-out device on the gripper carriage electromagnetic waves can be used with short range for reading the sensor.
- the senor is arranged on an end face and / or on the bearing of the roller.
- the end face of the roller is exposed to relatively low stresses compared to the lateral surface of the roller.
- a sensor arranged on the front side or on the bearing of the roller is particularly easy to access even during operation of the roller. As a rule, the smallest disturbances occur here in the contactless readout of the sensor.
- the roll change system comprises a aus- value device, which read-out parameters of the rollers involved in the change can be fed.
- Each roller is uniquely identifiable by the readout device according to the invention by an identification parameter. This, in turn, makes it possible to assign unique characteristics to the identified roller via the data evaluation device, for example via a list of concordance lists.
- the data evaluation device checks whether the rolling stock introduced or to be introduced into a specific rolling stand ze is scheduled to operate with this particular mill stand, in particular depending on a product to be produced. Information about rolling stands is therefore also preferably stored in the data evaluation device, in particular which rollers are to be operated in specific rolling stands, in particular with regard to a product to be produced.
- a roll changing car is usually associated with a specific rolling mill. If the identity of the roll and possibly the identity of the roll stand are determined by means of the read-out device arranged on the roll changing carriage, then it can be determined by means of the data evaluation device whether the roll and the roll stand should be operated together according to plan. Since in certain rolling stands only certain rollers may be operated in order not to change the properties of the product - the rolling stock, eg. Metal strip - undesirable manner, is checked by means of data evaluation, whether the roller mounted on the Walzencicwagen and provided for changing the corresponding roller Features. As a rule, a set of rolls, for example consisting of two work rolls, is exchanged simultaneously.
- the data evaluation device can issue a signal to a monitoring center. This can then take appropriate action. If necessary, the data evaluation device can fully automatically cause the identified roll with "false" properties on the particular roll change carriage to be exchanged for a roll with "correct” properties. Thus, it is possible to provide a roll with corresponding properties for the roll change carriage, if appropriate before a roll change takes place or before damage to the product occurs.
- the data evaluation unit is thus preferably designed at least for the management of the roll stock, in particular during roll change.
- the data evaluator automatically detects which rolls are being carried out of the mill and which rolls are being fed into the mill for operation become.
- the data evaluation device thus assumes the loading and unloading of the rollers and thus the documentation of roll changes. In the data evaluation device is thus always deposited, which rolls are currently in operation.
- the transport devices such as cranes or roller conveyor wagons, are also provided with readout devices, so that it is also possible to carry out location tracking of rolls carried out from the rolling stand in the rolling mill. Also, the location tracking of rolls can thus be done by the ausnceeinrich- tion.
- the operating state parameter can be detected by measurement.
- two principles of data acquisition are advantageously linked together.
- at least one operating state parameter can be read out from the sensor at any time technically.
- the roller is identifiable at any time on the basis of the stored identification parameters by means of the read-out device.
- measurement series for the operating state parameters can be recorded specifically for specific rolls and, for example, associated with the product quality of a product in which the roll is / was involved.
- the temperature of the roller, the vibration state of the roller, ie vibration frequency and / or oscillation amplitude of the roller, the position of the roller or the humidity of the roller environment can be detected by measurement as measured operating state parameters.
- sensors on the roll stand, on the work roll and on the frame drives, which detect the oscillation state of the respective saw By detecting the state of vibration of the respective rolls, it is possible to determine which roll has an exciter function for the resulting framework vibrations, which are disadvantageous in the production of metal products. due. Due to the rapid localization of the vibration exciter can be acted quickly to committees of the product, eg. Metal strip - caused by the skeletal vibrations - to keep as low as possible.
- the senor can be supplied with energy for operating the sensor by the read-out device. It is thus not necessary to provide the sensor with a power source which ensures its operation. Rather, the sensor works only when the readout emits a signal to read the sensor. As a result, the sensor can also be made compact and have a low weight.
- the readout of the sensor takes place by means of electromagnetic radiation.
- electromagnetic radiation is based on well-established and proven technology and is therefore reliable and easy to handle.
- a transmission power is provided for the read-out device, which is free from state approval procedures. In Europe, these are currently 100 mW (milliwatts). However, this may be subject to change.
- the data transmission preferably takes place in a frequency range from 2.4 GHz (gigahertz) to 2.4835 GHz, ie the ISM (Industrial, Scientific, Medical) range.
- the readout device and / or the sensor may be designed such that the traffic between them only works at a short distance, ie less than 1 meter, in particular in a range of 30 cm to 80 cm.
- the read-out device may, for example, comprise a directional antenna which emits a signal for reading out the sensor substantially in its direction.
- energy can be supplied to an electrically passive sensor, advantageously by means of electromagnetic radiation or electromagnetic waves, for operation.
- the sensor is designed such that a plurality of parameters can be detected together.
- a plurality of identification parameters, a plurality of operating state parameters or a combination of identification parameters and operating state parameters are transmitted by a single signal response of a sensor.
- the signal response includes, for example, the detected operating state parameters and the identification parameters.
- the basis of the signal response is, for example, the signal corresponding to an identification parameter.
- the signal associated with the identification parameter is, for example, modified in a defined manner by the measurement process of an operating state parameter such that the change of the signal corresponding to the identification parameter reproduces the operating state parameter.
- the senor is designed as a surface acoustic wave sensor, with a receiving and transmitting unit, with a signal converter arranged on a piezoelectric crystal for the mutual conversion of surface waves and electrical signals and with at least one reflector for reflecting surface waves.
- a receiving and transmitting unit with a signal converter arranged on a piezoelectric crystal for the mutual conversion of surface waves and electrical signals and with at least one reflector for reflecting surface waves.
- the receiving-transmitting unit is usually an antenna which receives signals, in particular electromagnetic waves, from the read-out device. These are converted into surface waves by the signal converter and the piezoelectric crystal. The surface waves propagate on the surface of the piezoelectric crystal.
- At least one reflector for reflecting surface waves is arranged on the piezoelectric crystal.
- a plurality of reflectors for example two or three, are provided. It can also contain up to 20 reflectors per surface wave sensor be provided.
- the surface waves, which are generally partially reflected at the at least one reflector, travel back to the signal converter and are converted back into electromagnetic signals there.
- the electromagnetic signals obtained from the surface waves are then radiated via the antenna of the sensor and received by the read-out device.
- each sensor can be designed individually or uniquely in this way.
- the arrangement of the at least one reflector determines an identification parameter.
- unique roll identification parameters can be provided for each sensor.
- Identity is provided by characteristic transit times or transit time differences of the signals between the signal converter and the at least one reflector. At least one identification parameter from the read-out identification parameters then makes it possible to unambiguously determine the identity of the roller from the read-out identification parameters.
- the surface wave sensor also enables a temperature measurement and a vibration measurement, since the transit time of the surface wave generated by the signal converter is dependent on the temperature and the vibration state of the piezoelectric crystal.
- operating state parameters in the form of the temperature and the vibration state detected by the sensor can always be read out without additional effort.
- a first roller has a first surface wave sensor and a second roller a second surface acoustic wave sensor, wherein the reflectors of the first and second surface acoustic wave sensor are arranged such that at simultaneous reading of the sensors Signals that correspond to the para- meters of the first roller and the read-out parameters of the second roller are assigned, do not overlap in time.
- a data processing device which read parameters can be fed.
- the data processing device receives the read-out detected operating state parameters and the read-out identification parameters.
- a database is created, which can be accessed individually for control purposes, tax purposes or documentation purposes for each roller.
- the data processing device is preferably supplied with further operating state parameters of the roller that are not detected or detectable by the sensor, as well as a multiplicity of further variables influencing the process.
- data about the production of the product or data about the product produced are also supplied to this data processing device.
- currently recorded operating state parameters can be used to control, control or optimize the roll or roll operation.
- An optimization of a roll is preferably carried out offline from the process, for example, after changing or removing the roller.
- Regulation and / or control of the rollers on the basis of the detected and read-out operating state parameters are preferably carried out during the operation of the roller, ie online.
- Successive read-out operating state parameters in conjunction with read identity parameters can For example, directly incorporated into a process model, and used to control the roller control variables. This can improve the product quality.

- the reflectors 8 and 9 are arranged one behind the other. Due to the distance of the reflectors 8 and 9 from the signal converter 7 and the reflectors 8 and 9 to one another, the first surface acoustic wave sensor 2 has an identity parameter which can be unambiguously assigned to this sensor 2.
- the sensor 2 'shown in FIG. 5 differs from the sensor 2 shown in FIG.
- the reflectors 8, 9 and 8 ', 9' of the sensors 2 and 2 ' are arranged such that with simultaneous reading of the sensors 2 and 2', the transit times of the surface waves from the signal converter 7 of the first sensor 2 to the reflector 8 and 9 and back to the signal converter 7 or from the signal converter 7 of the second sensor 2 'to the reflector 8' or 9 'and back are so different that the signals or the signal response of the first surface acoustic wave sensor 2 and the signals or the signal response of the second surface acoustic wave sensor 2 'does not overlap. Therefore, the sensors 2 and 2 'in the immediate vicinity of each other, for example. Same or different rollers are operated.
