Definitions
- the present invention relates to a method for monitoring a belt of a belt drive according to patent claim 1, a device for monitoring a belt of a belt drive according to patent claim 9 and a belt drive with such a device according to patent claim 10
- belts represent elongate bodies that transmit force in the elongate direction of extension.
- a belt usually has a flexible material, which in particular can be rubber or a polyurethane material.
- Tension members are usually embedded in the flexible material in order to transmit the tensile forces in the longitudinal direction of extension.
- Such belts can be used open or closed endless.
- Belts of this type include elevator belts, drive belts, transport belts or conveyor belts, which can also be referred to as transport belts or conveyor belts.
- Such and other types of belts can also be used in the agricultural sector in addition to industrial applications.
- EP 3483472 A1 describes a belt made of a flexible material on which electronics are arranged, by means of which at least one State variable of the belt can be measured and wirelessly forwarded to a remote receiving unit.
- a pocket is attached to the radial outside of the belt and the electronics are arranged in a receiving space of this pocket.
- EP 3451 817 A1 describes a drain belt having a carcass, a plurality of cleats extending from the carcass, a plurality of V-guides disposed perpendicular to the plurality of cleats, and at least one sensor for Measuring and reporting information on important measurable properties of drip tape.
- the key measurable properties can be relayed to an operator, a control system, or a combination thereof.
- the sensors measure and report potentially harmful drip belt conditions.
- the sensors measure and transmit in real time so that one or more characteristics of the drip tape can be determined in situ.
- EP 3471 530 A1 describes a belt monitoring system for an agricultural belt assembly, the monitoring system comprising an agricultural belt with a magnetic element embedded therein and a sensor.
- the agricultural belt assembly defines correct belt alignment for the belt and moves the belt.
- the magnetic element is polarized to emit a magnetic signal.
- the sensor is configured to sense the magnetic signal output from the magnetic element at a reference position.
- the monitoring system further includes circuitry configured to output a signal when, for example, the agricultural belt moves through the agricultural belt assembly more than a predetermined amount without the sensor assembly detecting the magnetic signal emitted by the magnetic element. a predetermined period of time elapses without the sensor detecting the magnetic signal and the circuit determining that the Position of the magnetic element is outside a permissible position range.
- DE 19643997 A1 describes a method for monitoring an endless circulating belt or belt with a connection area, in particular a method for monitoring a conveyor belt with a connection area, the beginning and end of which occupy a specified distance from one another in the unloaded, undamaged state, with or there is at least one transponder on the belt, which transmits a signal to an external transmitter/receiver device when it passes through an effective area, with at least one transponder being arranged at the beginning and at the end of the connection area and the method being carried out in the following method steps:
- the transponder located at the beginning of the connection area sends a signal to the external transceiver at a point in time;
- the transponder located at the end of the connection area sends a signal to the external transceiver at a later point in time;
- the intervening period of time is determined
- One object of the present invention is to provide a method for monitoring an endless circulating belt and a corresponding device of the type described at the outset, so that the monitoring options can be expanded. At least one alternative to known methods and devices of this type should be created.
- the object is achieved according to the invention by a method with the features according to patent claim 1, by a device with the features according to patent claim 9 and by a belt drive with the features according to patent claim 10.
- the present invention thus relates to a method for monitoring a belt of a belt drive, having at least the following steps:
- Such a belt can in particular be a drive belt, a transport belt or a conveyor belt or the like for both industrial and agricultural applications.
- the detectable element can be any element that can be detected by sensors, including optical detection.
- a detectable element can be detected electrically or electromagnetically, in particular as a transmitter of a signal, as will be described in more detail below.
- the detectable Element can be embedded in a flexible material of the belt or arranged on one side of the belt.
- the present invention is based on the finding that the speed of a belt can be determined easily and reliably in this way.
- the determined speed can be used as such and, for example, only displayed as information, for example to a user of the belt drive.
- the determined speed can also be processed further in addition or as an alternative, in order in particular to be able to monitor the condition of the belt or the belt drive.
- the speeds per detectable element can then be determined in each case.
- the speeds determined can be verified against one another or averaged.
- the capturing of the detectable element includes capturing a time stamp of the detectable element. with other information can be generated and made available by the detectable element when detecting. This can improve the determination of the time difference and thus also the accuracy of the speed determined therefrom.
- the detection of the detectable element includes a detection of a sensor value of the detectable element.
- sensor information can also be transmitted.
- a detection or transmission of at least one sensor value of the detectable element that takes place anyway can also be used to determine the speed.
- the sensor value of the detectable element includes a sensed temperature. This can be advantageous because conclusions can be drawn about the condition of the belt from the temperature of the belt detected by sensors. This can be useful for monitoring the belt.
- the detected temperature is detected by means of a SAW sensor of the detectable element.
- the temperature is thus recorded using a surface acoustic wave sensor. Accordingly, this type of sensory detection can be used in this method and its properties and advantages can thus be used.
- detecting the detectable element includes detecting an identification of the detectable element. This can simplify the identification of the detectable element, particularly when using multiple detectable elements of the belt, or ensure correct identification.
- the belt is an agricultural belt. Accordingly, the method of the present invention can be used on belts for agricultural applications.
- the belt is a V-belt.
- the inventive method on belts can be used for this type of belt.
- the present invention also relates to a device for monitoring a belt of a belt drive with a belt having at least one detectable element, having a receiver designed to detect the detectable element, and having a control unit designed to use a method as described above to execute.
- a device can be made available in order to implement the method described above.
- the present invention also relates to a belt drive with at least one device as described above.
- the properties and advantages of a method according to the invention can be used in a belt drive.
- FIG. 1 shows a schematic representation of a belt drive according to the invention with a device according to the invention for carrying out a method according to the invention.
- a belt drive 1 has a drive roller 12 and a deflection roller 13 in order to be able to move an endlessly closed belt 10 in a running or movement direction A.
- the belt 10 is in particular a V-belt 10.
- the belt 10 has a detectable element 11 in the form of a sensor 11, for example for sensory detection of the temperature of the belt, or a transponder 11. In any case, the detectable element 11 can have a unique identification and time information.
- a receiver 14 and a control unit 15 are also present on the belt drive 1 side.
- information can now be transmitted from the detectable element 11, which can contain the identification of the detectable element 11, the detected sensor value such as a temperature, and time information in the form of a time stamp of the other information.
- This transmission can take place in particular after a corresponding request by the recipient 14 . This can take place at two points in time for two immediately subsequent revolutions of the belt 10 .
- the control unit 15 can now use the information received in each case to form or determine the time difference. Furthermore, the control unit 15 can divide the known length of the closed belt 10 by the specific time difference and thus determine the speed, which can then be used in a variety of ways.
