Definitions
- the invention relates to a method for recording usage data of rollers.
- DE 10 2016 009 600 A1 discloses a method for recording usage data of rolls which are used for the manufacture or processing of web-shaped goods, in which accelerations on a rotating roll are carried out with a sensor device installed in the end face of a roll recorded and a time between these slimes is documented on a data storage device in order to determine the actual useful life.
- the determination of accelerations ensures that data is only recorded when the roller is moved laterally or rotates.
- the invention is therefore based on the object of further developing such a method, a data processing device and a modified roller.
- This processed data can include stress data that document the stress on the roller.
- the sensor and data processing device are located at different locations on the roller, it is advantageous if the data have expansion or bending data of the surface of the roller.
- the data contain corrosion data.
- the data can be recorded with an electrochemical measuring cell.
- a DC voltage applied to an electrode can be varied in order to determine the nonlinearity of the ohmic component of the Faraday impedance.
- a first time can be documented when a certain initial acceleration value is exceeded and a second time or the time period between these acceleration values can be documented when the value falls below a certain final acceleration value.
- the combination of these times with further data opens up the possibility of evaluating the further data in correlation with the time period of use and recognizing whether the further data lie in the useful life or incidents outside the useful life can be assigned. It is therefore also advantageous if acceleration values are measured continuously or in discrete steps during the time period 2 between the initial acceleration value and the final acceleration value. This makes it possible not only to record the times in which a certain acceleration value is exceeded, but also to record acceleration values during these times in order to assess these times qualitatively.
- a special embodiment variant provides that the acceleration values are measured on the opposite sides, in particular end faces, of the roller. This makes it possible to determine peak loads and torsional forces on the roller.
- the measuring devices can be connected to one another or connected to a third device that records the data and, if necessary, also calculates them in order to make additional data available or to compress the recorded data. This makes it possible, in particular, to determine difference values between measured values on opposite sides of the roller, which can be inferred from a torsion, a lateral displacement or a movement on a circular path or other irregularities.
- the method measures a lateral acceleration value. This makes it possible, on the one hand, to document the movement of a non-rotatably mounted roller and, on the other hand, to determine deviations from an ideal, circular rotary movement around a stationary line in the case of a rotatably mounted roller.
- a constructively advantageous embodiment variant provides that the data processing device is inserted into the end face of a roller outside the center thereof. On the one hand, there is usually enough space here for such data processing. Arrange device and on the other hand, this facilitates access to the data processing device.
- the data store be wirelessly connected to a computer or can be connected to it.
- the data storage device be connected or can be connected to a reading device or a computer via a cable.
- a particularly advantageous embodiment variant provides that the usage data are read out of the memory in a wire-bound manner and the data processing device is electrically charged in the process.
- Such a sheet-like product is, for example, a film or sheet made of metal or plastic.
- the roller can serve to drive the web or to wind or unwind the web on it.
- the method is proposed in particular for an area of application in which paper is wound up or unwound onto the roller or a paper web is guided with the roller.
- a special embodiment variant provides that data is also recorded when the roller is not rotated about its own longitudinal axis. Training even when the roller is not moving. That is, even if the roller is neither rotating nor being moved locally in the room.
- the processed data are subsequently documented on a data storage device.
- the processed data are used for control or regulation. For example, an acceleration measured on the roller can be used to control a roller or crane drive.
- a data processing device having a sensor and a data memory is suitable for many applications of the method according to the invention.
- this data processing device can be inserted into a preferably cylindrical opening on the end face of a roller and is suitable for recording acceleration values and other data.
- these acceleration values can be a wide variety of values which indicate the use of the roller and the further data are data which, in addition to recording the service life, provide further information.
- This data processing device preferably has an interface. This interface is used for data transmission in order to transmit the acceleration values to a computer for evaluation. However, the data processing device can also have a computer which already evaluates the data and only transmits compressed data via the interface and / or a plug connection.
- a special embodiment variant provides that a display or data transmission is activated when a limit value is exceeded. For example, not only can information about roll overhaul be issued outside of the data processing device based on the usage data, but the data processing device itself can also display such a value or a value overrun. For this purpose, the data processing device can have a status display which indicates the forecast time until the next overhaul or only shows the charge status of the power supply of the data processing device. This makes it possible to point out at an early stage the necessity and the approximate time of the revision of a roller.
- the data processing device can be arranged on a circuit board. However, it is advantageous if it has not only a circuit board but also a processor circuit board which is designed to record different data and a processing circuit board. which is designed for processing data on time, acceleration and speed.
- the object on which the invention is based is also achieved with a roller which has a cylindrical opening outside the center, into which a data processing device is inserted.
- the roller preferably has a data processing device on two opposite sides, each outside the center. This data processing device is preferably arranged on the end face of the roller.
- the roller has a cylindrical opening with a diameter of 30 to 70 mm and preferably of 50 mm.
- this cylindrical opening has a diameter of 30 to 70 mm and preferably 50 mm, in which a data processing device is arranged.
- An exemplary embodiment of a roller according to the invention is shown in the drawing and is explained in more detail below. It shows
- Figure 1 is a three-dimensional view of a roller with data processing device
- FIG. 2 shows a detail from FIG. 1.
- the roller 1 shown in FIG. 1 has a data processing device 4 on its end face 2, decentral to the central shaft 3.
- This data processing device 4 is arranged in a cylindrical opening 5.
- a further data processing device (not shown) is provided outside the center 6 of the roller.
- the cylindrical opening 5 has a diameter of 50 mm and the roller 1 has a diameter of more than 500 mm, so that the data processing device 4 is arranged in a relatively small cylindrical opening on the end face of the roller 1.
- the data processing device 4 has a sensor 7 and a data storage device 8.
- the device is powered by a power supply 9, which in the present case is a rechargeable battery.
- the data in the data memory 8 can either be read out via a cable 10 via an interface or wirelessly or can be displayed in the display 11.
- the data processing device 4 has a computer 12 which, in the exemplary embodiment, is also connected to the data processing device 4 (not shown) on the opposite end of the roller 1.
- the data processing device 4 is thus a roller-fixed component for recording the usage data of the roller.
- the data processing device device 4 on the face 2 of the roller 1 in a bore, that is, the cylindrical opening 5, inserted flush outside the center 6 of the roller 1.
- the data processing device 4 is thereby housed in the roller body of the roller 1 and protected against external influences.
- the rotation of the roller 1 activates the data processing device 4 from a defined speed and thus from a defined centrifugal acceleration. If the speed falls below this or another defined speed, the data processing device 4 is stopped. During the active phase of the data processing device 4, the measured values are recorded on the data memory 8.
- the data can be called up by the operator from the data memory 8 wirelessly or via a wired connection.
- the battery 9 can be charged at the same time.
- the data read out are recorded in a database and compared there with specified data.
- the properties and specifications of the roller can be deduced from the comparison of the data on the data memory 8 with data in the database.
- the interface 10 is used for data transmission to a device of the operator and enables a status display.
- This status display can provide information about the state of charge of the internal battery or the memory.
- a plug connection 13 forms a protected connection for connecting a communication and / or charging cable (not shown).
- the roller-fixed data processing device 4 determines data for determining the usage times, a usage profile or a load profile. If two data processing devices are used on opposite end faces 2 of the roller 1, wireless communication is preferred provided between these two data processing devices 4 in the interior of the roller 1.
- a computer which can be provided in the data processing device 4 or can also be used outside as a component that is not fixed to the roller, enables the evaluation of the data, the linking and a plausibility check of the data with one another and a comparison with predetermined values as application-oriented usage data .
- a first stage of the data processing device enables on / off detection. When a defined roller speed or centrifugal acceleration is reached, the data processing device switches a contact or switch. The sensor switches or sets a time stamp and creates a stamp log. Here, a date is stored with a time. After falling below the threshold, stamping is carried out. This means that another date and time are saved. This provides an overview with documentation of the service life due to the exceeding of threshold values.
- the data processing device 4 can determine a usage profile based on the measurements of level 1. For this purpose, a date and time are stored after the threshold is reached. When this threshold is reached, a load sensor continues to be activated.
- This load sensor is generally an acceleration sensor that detects acceleration as a function of time. It is preferably sampled at a low frequency. After falling below the threshold, the load sensor is stamped and consequently deactivated. This enables an overview or a series of measurements in the "Acceleration over time" display.
- a level 3 based on level 2 determines a load profile by using a pair of data processing devices on both end faces of the roller.
- the data processing devices are linked and connected in order to other timestamps and thresholds.
- the load sensors are acceleration sensors that record acceleration as a function of time in several levels.
- sample rate and storage cycle By using two sensors and measuring in different levels, a load profile can be derived from which peak loads with a time stamp can be found.
