Description

[0001] SYSTEM AND METHOD FOR CONVEYOR MONITORING [0002]

And more particularly, to a conveyor monitoring system and method for detecting temperature, velocity, and pressure information in a sensor attached to each conveyor region and grasping state information for each region of the conveyor.

Unless otherwise indicated herein, the contents set forth in this section are not prior art to the claims of this application and are not to be construed as prior art to be included in this section.

 Generally, a conveyor system is mainly used for various moving equipment such as a conveying line for transporting a conveying object such as a stone, coal, cement, etc. from a loading facility to a loading place. The conveyor system includes a conveyor belt for conveying a conveyed object placed thereon in one direction, a drive pulley and a return pulley installed on both sides of the conveyor belt for rotating the belt, and a conveyor belt for supporting the lower portion of the conveyor belt, A conveying roller and a return roller for preventing the conveying roller, and a support for supporting the conveying roller at a predetermined height.

The conveyor system can be formed by arranging a plurality of conveyor belts in a straight line arrangement in a case where the conveying distance is long, such as a line for conveying a conveyed object from a maritime unloading facility to a loading place. When it is necessary to switch the conveying direction, a shuttle and a chute for switching the conveying direction are provided at the corresponding portion so that the conveying object can be branched and conveyed to another belt conveyor.

However, in general, when the edge of the conveyed object is sharp or sharp iron pieces are mixed in the conveyed object, the conveyor belt is often damaged. At this time, the conveyor belt can be cut in the longitudinal direction within a short time when the conveyor belt is conveyed. Particularly, there is a case where a specific portion is worn by friction between the conveying roller and the conveying roller due to the load of the conveying object, and the conveying belt is incised with the load concentrated on the corresponding portion.

Various devices and methods have been developed and used to detect whether the conveyor belt of the conveyor system is damaged or incised to prevent incision of the conveyor belt. In the case of detecting the incision of the conveyor belt by using the double ultrasonic sensor, there is a problem that the ultrasonic sensor malfunctions due to dust or the like generated in the object to be conveyed or malfunctions due to noise caused by other devices.

Further, when detecting whether or not the conveyor belt is incised by using the metal detector, there is a problem that non-ferrous metal or other substances other than the metal material can not be detected, and the conveyor belt itself can not detect the pressure and deformation according to the amount and the load of the conveyed object It is difficult to detect the damaged state of the conveyor belt. Particularly, the conventional conveyor belt sensing device does not have an integrated monitoring system for the damage of the conveyor belt components such as the bearings of the conveying rollers.

Therefore, the definition should be based on the contents throughout this specification.

1 is a view of a conveyor monitoring system according to an embodiment.

Referring to FIG. 1, the conveyor monitoring system may include a conveyor 100, a central management server 200, and an administrator terminal 300. The conveyor 100 of the monitoring system according to the embodiment senses state information for each conveyor region through the state detection sensor and transmits the state information to the administrator terminal 300 and the central management server 200. For example, in the conveyor 100, a state sensing sensor including temperature, pressure, current, and magnetoresistive sensor (MR) and velocity sensor is mounted in each zone, and a conducting mesh is distributed on the belt. In the embodiment, the state detection sensor and the conductive mesh can determine the state of the conveyor belt by area.

The central management server 200 determines the state of the conveyor and the conveyor belt for each zone on the basis of the data transmitted from the state detection sensor. Further, when the current blocking region is detected in the conductive mesh, it is determined that the conveying belt in the region including the current blocking region is broken. Specifically, when the conveyed object such as cement is moved by a conveyor belt, if the conveyed object load is more than a certain level, or when the conveyor belt is damaged, the conductive mesh formed on the conveyor conveying belt is broken, It stops. In the embodiment, the central management server 200 grasps the area where the current is not supplied in the conductive mesh and stops the conveyor operation.

The manager terminal 300 receives the conveyor status information for each zone from the central management server 200 and receives the conveyor operation information including the occurrence of the current blocking area and the operation error of the conveyor belt in the central management server 200.

In addition, the central management server 200 stores detailed information of parts such as specification of various parts attached to the conveyor, installation time, and the like. The central management server 200 notifies the manager of the replacement timing of the specific part through the detailed information of the parts stored in advance, and detects the state information of the parts mounted on the conveyor with the data collected through the part information and the state detection sensor The replacement time, and the normal operation, and transmits the determination result to the administrator terminal 300.

The conveyor 100 according to the embodiment can detect the damage of the conveyance belt through the conductive mesh provided on the conveyance belt, the temperature sensor provided on the conveyance belt rotation roller, and the speed detection sensor. For example, the conveyor 100 simultaneously detects the current flowing through the conductive mesh, the surface temperature of the roller sensed by the temperature sensor, and the rotational speed of the roller calculated by the speed sensor and the MR sensor, . In the embodiment, it can be judged that a region where no current flows in the conductive mesh occurs, or when the surface temperature of the roller is less than the lower limit value or exceeds the upper limit value, and when the rotational speed of the roller is less than the threshold value, have.

2 is a view showing a conductive mesh constituted by a conveyor according to the embodiment and a conveyance belt of the conveyor.

2, the conveyor includes a computing board 5 equipped with a pressure and magnetoresistive sensor (MR), a velocity sensor, a determination unit, a current supply unit, a magnet, a lighting device, And a conveyance belt 3, as shown in Fig. As shown in Figs. 2 (b) and 2 (c), the conductive mesh net is provided on the conveyance belt 3. Fig. In an embodiment, the mesh network is installed in the upper layer of the conveyor belt, so that it is possible to detect when the pressure applied by the transporting object exceeds a certain level, or when the mesh is damaged by a sharp object transported to the belt . When the supply of current to the mesh network is interrupted due to damage to the belt 3 by the transporting object 7, the mesh detects the interruption of the current supply by the current sensor and the MR sensor, Stop the belt operation. In the event of damage to the belt, the driving of the belt, i.e., the conveying action, is stopped so that the damaged area on the belt is no longer enlarged. This minimizes the cost incurred by the conveyor belt damage.

When the conveying roller starts to rotate, the surface temperature and speed of the conveying roller and the electromagnetic force of the magnet are measured and the color of the light emitting diode is displayed differently according to the current value calculated by the temperature, the speed and the electromagnetic force. To be judged visually.

3 is a block diagram showing a data processing block of the conveyor 100 according to the embodiment.

Referring to FIG. 3, the conveyor 100 may include a collecting unit 110, a determining unit 130, and a communication unit 150.

The collecting unit 110 collects the state information of the conveyor device in the various states of the state sensor including the temperature sensor, the pressure sensor, the MR sensor, the current sensor, and the speed sensor.

The determination unit 130 determines whether the conveyor belt is normally operated on the basis of the state information collected by the collecting unit 110. For example, the determination unit 130 may determine whether the conveyor belt bearing is damaged by using the surface temperature of the conveying roller provided on the conveyor conveyance belt and the current value measured by the MR sensor. When the instantaneous partial pressure detected in each area of the conveyor belt exceeds a threshold value, the judging unit 130 operates the vibration device to adjust the instantaneous partial pressure of the instantaneous partial pressure detected region exceeding the threshold value . The communication unit 150 transmits to the central server 200 whether status information and normal operation of each conveyor belt are provided.

4 is a block diagram illustrating a data processing block of the central management server 200 according to an embodiment of the present invention.

Referring to FIG. 4, the central management server 200 may include an operation unit 210, a determination unit 230, and a control unit 250.

The operation unit 210 receives the detailed information including the state information, the specification of the part mounted on the conveyor belt and the time of first use from the conveyor conveyance belt, identifies the part replacement time based on the detailed information, , The position of the abnormal part and the replacement timing for each part are calculated.

The determination unit 230 determines whether or not the conveyor belt is abnormal in each zone based on the status information. The determination unit 230 can determine whether the conveyor belt bearing is damaged by using the surface temperature of the conveying roller provided on the conveyor belt and the current value measured by the MR sensor.

The control unit 250 controls the operation of the conveyor belt in accordance with the abnormality, and stops the operation of the conveyor belt including the current interruption region when the current interruption region is detected in the conductive mesh.

In the conveyor monitoring system according to the embodiment, the manager makes it possible to visually check the roller rotation and the normal state of the temperature in the field, amplify the data sensed by the magnets attached to the conveyor and the MR sensor, So that it can be accurately measured.

In the embodiment, a magnet and an energy conversion module are provided on the conveyor so that the kinetic energy generated when the conveyor belt roller rotates can be converted into electrical energy to operate the LED lamp. It is possible to visually confirm whether the roller operates normally by the LED operation by the self-power generation. Further, in the embodiment, the LED lighting color is controlled to change according to the roller rotation reference speed so that the state of the conveyor conveyance belt roller can be grasped. In addition, the LED lighting color is changed according to the surface temperature of the roller so that the administrator can grasp the roller state visually. For example, if the surface temperature of the roller is 26 degrees or less, the LED lights up in a blue state indicating a steady state. If the roller temperature is less than 38 degrees, the LED is turned on. If the surface temperature is 38 degrees or more, So that the manager can quickly perform a response corresponding to the roller state.

5 is a data processing flowchart for determining whether or not a conveyor belt abnormality exists in the conveyor according to the embodiment.

In step S10, the temperature of the transport roller surface is measured by the temperature sensor of the conveyor.

In step S15, it is determined whether the measured surface temperature is within the normal temperature range. If the measured temperature is within the normal temperature range, the process returns to step S10. If the measured temperature is out of the normal temperature range, step S20 determines whether the measured temperature exceeds the upper limit value. If the measured temperature exceeds the upper limit value, the MR sensor acquires the magnetic field data in step S25, and measures the current in step S30. In step S30, the current flowing through the conveyor belt can be measured through the current measured through the magnetic field data and the current measured through the current sensor. Further, in the embodiment, the current flowing through the mesh net provided on the conveyor belt can be measured as the current flowing through the conveyor belt. Specifically, when the roller provided on the conveyance belt operates, the magnet is caused to reciprocate in the enameled wire coil to generate a current, thereby generating an electromagnetic force, and the MR sensor can measure the electromagnetic force. Since the electromagnetic force measured by the MR sensor is proportional to the current, in the embodiment, the current can be measured through the MR sensor as well as the current sensor so that the current flowing in the roller can be grasped more accurately. To this end, the conveyor according to the embodiment may include a magnet and an energy conversion module on the conveyor belt roller. Also, in the embodiment, the rotation speed and the rotation speed of the idler roller provided on the conveyance belt can be sensed through the MR sensor. Specifically, since the electromagnetic force changes due to the rotation speed, the number of revolutions, and the current of the roller, the MR sensor measures the electromagnetic force that changes due to the roller rotation so as to judge whether the roller operates normally.

In step S35, it is determined whether the current value measured by the MR sensor or the current sensor exceeds the upper limit value. If the upper limit value is not exceeded, the process returns to step S25. If the upper limit value is exceeded, the conveyor determination unit 230 determines the conveyor belt failure in step S40. In step S45, a warning signal for the breakage of the conveyor belt is output.

If the temperature of the conveyor belt is less than the upper limit value in step S20, the process proceeds to step S70 and it is confirmed whether the surface temperature of the conveying roller is lower than the lower limit value. If it is less than the lower limit value, the judging unit detects the foreign substance through the state information of the conveyor belt received from the state detecting sensor in step S50. If the foreign substance is detected in step S55, it is determined whether the weight of the foreign substance exceeds the upper limit value. In step S60, when the weight of the foreign substance exceeds the upper limit value or the pressure sensed by the pressure sensor exceeds the upper limit value, it is determined that the bearing is damaged. In step S65, the warning signal is output.

The conveyor monitoring system according to the embodiment detects the surface temperature of the conveyor conveying roller to judge whether the conveying belt is damaged or not, and informs the administrator of the result of the damage, so that an immediate repair work can be performed for the damage of the conveyor conveying belt.

It precisely detects the damage condition of the conveyor belt due to the load of the conveying object, thereby preventing malfunction during conveyance. In addition, if damage to the conveyor belt is detected, the conveyor operation is immediately stopped so that the damaged area of the conveyor conveyor belt is not extended. In addition, maintenance information of the bearings of the conveying rollers is managed by the server, and the components are periodically replaced, thereby improving safety.

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It is not limited to the embodiment.
