Definitions
- the present invention relates to a wear detecting device for a conveyor belt that detects the wear of a compare belt in a non-contact manner.
- a wear detection layer having a hue (for example, white rubber) different from that of the elastic layer of the belt is embedded in the belt, and the wear detection layer appears outside when the elastic layer is worn. Therefore, there is one that determines wear (for example, see Patent Document 1).
- ultrasonic thickness meter that determines wear by periodically measuring the thickness when the conveyor belt is stopped.
- a transbonder is embedded in the belt at different depths from the surface, and either of them passes through the belt as a result of the force being broken or falling off as the belt wears. Some have been detected near an antenna portion having a transmission coil and a sense coil disposed near the place where the belt is to be worn, so that it is possible to know how much the belt has been worn (see, for example, Patent Document 2).
- Patent Document 1 JP 2004-35115 A
- Patent Document 2 West German Patent No. 19525326
- the present invention can detect the amount of wear of the conveyor belt automatically and easily and accurately during operation, and has a simple configuration. It is an object of the present invention to provide a wear detecting device for a conveyor belt that can be implemented at low cost.
- a rubber magnet magnetized in the thickness direction is embedded in the conveyor belt so as to be inclined with respect to both the traveling direction and the thickness direction, and the rubber magnet is worn due to wear of the conveyor belt.
- a magnetic sensor for detecting a change in magnetic force is disposed at a position where the rubber magnet passes.
- a rubber magnet is inserted between the surface from the surface of the conveyor belt to the internal reinforcing material to the internal reinforcing material.
- the conveyor belt is arranged in a staircase pattern in both the traveling direction and the thickness direction.
- the rubber magnet is a bonded magnet in which magnet powder is mixed in a rubber matrix and magnetized.
- the change in the rubber magnetic force embedded in the conveyor belt is detected by the magnetic sensor, and based on the change, the wear of the conveyor belt is detected together with the rubber magnet.
- the wear of the conveyor belt can be automatically detected in a non-contact manner, and the rubber magnet can follow the deformation of the conveyor belt. It can be prevented from dropping or dropping out.
- the rubber magnet is embedded in an inclined state, and the wear of the outer edge force can be detected linearly, and the wear amount can be accurately detected with only one rubber magnet. Therefore, the structure is simple and can be implemented at low cost.
- the amount of wear is accurately determined by the arithmetic control unit from the time difference between the starting point of the change in magnetic force during constant speed running of the conveyor belt and the peak value during measurement. Can do.
- the rubber magnet is placed between the surface from the surface of the competitor belt to the internal reinforcing material to the internal reinforcing material, and the rubber magnet is moved in the traveling direction and thickness. Since it is arranged stepwise with respect to both directions, it is difficult to detect with a magnetic sensor, the starting point of the change in magnetic force can be accurately detected digitally, and detection accuracy is improved. Can do.
- the reinforcing material when the initial thickness from the surface of the competitor belt to the internal reinforcing material is T, the reinforcing material is also directed toward the surface of the competitor belt at least in the range of TZ 3. Since the rubber magnet is stepped, the belt life at the end of wear can be accurately detected.
- the rubber magnet is mixed with the magnet powder in the rubber matrix. Since it is a bonded magnet, a thin rubber magnet with high flexibility following the belt can be formed, and a rubber magnet with high durability can be obtained.
- FIG. 1 is a side view of an unloading side end portion of a belt competitor provided with a first embodiment of the present invention.
- FIG. 2 is an enlarged cross-sectional view of a portion II in FIG.
- FIG. 3 is an enlarged view taken along line III-III in FIG.
- FIG. 4 is a block diagram of a control device.
- FIG. 5 is an output waveform diagram of the magnetic sensor force.
- FIG. 6 is an enlarged cross-sectional view of a portion similar to FIG. 2, in a belt competitor including a second embodiment of the present invention.
- FIG. 1 is a side view of an unloading side end portion of a belt competitor provided with a first embodiment of the present invention.
- Fig. 2 is an enlarged vertical side view of part II in Fig. 1
- Fig. 3 is an enlarged view of line III III in Fig. 1.
- the wear detection device is disposed near a place where the conveyor belt (2) passes, and the rubber magnet (3) embedded on the surface side of the conveyor belt (2) hung on the pulley (1).
- the rubber magnet (3) includes a magnetic sensor (4) for detecting the magnetic force of the force.
- the rubber magnet (3) is composed of a plate-like body magnetized in the thickness direction.
- the rubber belt (2) has a traveling direction (in the direction of arrow A in FIGS. 1 and 2) and a thickness direction. It is buried incline in both directions.
- the rubber magnet (3) has its base end (3a) in contact with the reinforcement (5) and its tip (3b) is exposed on the surface of the competitor belt (2).
- the conveyor belt (2) is buried over the entire width direction.
- a magnet obtained by magnetizing in the thickness direction a bond magnet in which a magnetic powder is dispersed and mixed in a rubber matrix to form a sheet is preferably used.
- a bond magnet is not only thin but also flexible and can easily follow the deformation of the conveyor belt (2).
- the magnet powder can have a strong magnetic force by using a rare earth magnet such as neodymium iron boron or samarium iron nitrogen, an arco magnet, or the like, in which ferrite is generally used.
- a rare earth magnet such as neodymium iron boron or samarium iron nitrogen, an arco magnet, or the like, in which ferrite is generally used.
- the magnetic sensor (4) may be a gauss meter, a loop coil or the like, and is disposed as close as possible to the passing position of the rubber magnet (3).
- the mounting position of the magnetic sensor (4) is preferably on the return side of the conveyor belt (2) as shown in FIGS. Accordingly, it is possible to detect at a clean location after being scraped off by the conveyed product force S scraper (6) conveyed by the conveyor belt (2).
- a width direction guide (7) for regulating the position in the width direction of the conveyor belt (2) passing therethrough, and the magnetic sensor
- a thickness direction guide (8) is provided to keep the relationship between the conveyor belt (2) and the magnetic sensor (4) constant.
- FIG. 4 is an example of a control device for the wear detection device for the conveyor belt (2).
- the control device inputs the detection signal from the magnetic sensor (4), calculates the degree of belt wear !, and transmits it from the transmitter (9). And sent Signal is received by the receiver (11), the calculation result is output to the output terminal (12), and when the wear level exceeds a predetermined threshold value, an alarm is issued or the belt compressor (2) is activated. And a central control unit (13) for performing necessary processing such as stopping.
- FIG. 5 shows an example of an output waveform from the magnetic sensor (4).
- the conveyor belt (2) travels in the direction of the arrow (A) in Fig. 2, and when the rubber magnet (3) passes through the position facing the magnetic sensor (4), the signal accompanying the change in magnetic force Is output. Since the wear of the conveyor belt (2) starts from the surface side force used for conveyance, the rubber magnet (3) is scraped off from the front end (3b).

Note that the same or similar members as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
