Description

Technical Field

[0001] The utility model relates to the technical field of deviation switch protection devices, in particular to a deviation protection control device for a belt conveyor. Background Technique

[0002] At present, all deviation switches detect the distance from the vertical roller sensor to the belt edge of the belt conveyor. The installation distance is usually required to be 50-100 mm. The spring cam is used to reflect the deviation angle value, and a switch signal is sent after comparing with the set angle value.

[0003] Although most deviation switches are installed in pairs, usually only based on the unilateral offset of the belt, the start and stop of the belt are directly controlled, and misoperation is likely to occur. Since such switches have strict requirements on the installation environment and the use environment, misoperation is likely to occur if the installation is not in place or the use environment changes, and it is easy to cause mis-stopping, affecting the production of the production line and seriously affecting the production efficiency and operation and maintenance workload of the factory. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is: aiming at the above problems, a deviation protection control device for a belt conveyor is provided.

[0005] The technical solution adopted by the utility model is: a deviation protection control device for a belt conveyor, characterized in that it includes:

[0006] A first deviation switch, arranged on either side of the belt conveyor, and the first deviation switch can detect the offset of the belt on the side close to the belt conveyor;

[0007] A second deviation switch, arranged on the opposite side of the belt conveyor where the first deviation switch is arranged, the second deviation switch is symmetrically arranged with the first deviation switch, the second deviation switch is communicatively connected with the first deviation switch, and the second deviation switch can detect the offset of the belt on the side close to the belt conveyor;

[0008] A controller, arranged inside the first deviation switch and the second deviation switch, can obtain the offsets detected by the first deviation switch and the second deviation switch. The controller compares the offsets on both sides of the belt to obtain the actual deviation direction of the belt, and sends out corresponding control signals based on the actual deviation direction of the belt;

[0009] An actuator, arranged inside the first deviation switch and the second deviation switch, can receive the control signal and send out corresponding action signals based on the control signal, so that the belt starts or stops.

[0010] Through the above technical means, the first deviation switch and the second deviation switch are used to detect the offset amounts on both sides of the belt respectively. The controller obtains the offset amounts on both sides and compares them to obtain the actual deviation direction of the belt, and issues corresponding control signals based on the actual deviation direction. The actuator issues corresponding action signals based on the control signals, so that the belt can be started or stopped correspondingly.

[0011] In some embodiments, both the first deviation switch and the second deviation switch include an infrared detector, a data wire, and a power supply module. The infrared detector is installed on both sides of the belt conveyor through a mounting bracket. The infrared detector is connected to the power supply module, and the infrared detector is connected to the corresponding controller through the data wire. The controller is also provided with a communication interface.

[0012] In some embodiments, the communication interface is an RS485 data interface, and the communication interfaces of the first deviation switch and the second deviation switch are connected through a communication twisted pair.

[0013] In some embodiments, the power supply module uses a solar cell.

[0014] In some embodiments, the laser head of the infrared detector is vertically oriented towards the edge side of the belt.

[0015] In some embodiments, both the first deviation switch and the second deviation switch are provided with a protective housing.

[0016] In some embodiments, the actuator realizes the start-stop control of the belt by sending an action signal to a PLC or a control cabinet.

[0017] The beneficial effects of the present utility model are:

[0018] 1. By arranging the first deviation switch and the second deviation switch on both sides of the belt conveyor respectively, the first deviation switch and the second deviation switch are used to detect the offset amounts on both sides of the belt on the belt conveyor respectively. By comparing the offset amounts on both sides, the actual deviation direction of the belt is obtained, and then the corresponding start-stop actions of the belt are controlled according to the actual deviation direction. Compared with the traditional control method based on unilateral detection of the offset amount, the detection accuracy is effectively improved, the risk of misoperation caused by improper installation or changes in the use environment is reduced, and the installation requirements for the deviation switch are also reduced.

[0028] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solution of this utility model will be further described below in conjunction with specific embodiments.

[0029] In conjunction with Figures 1 to 3As shown in the figure, this embodiment is a deviation protection control device for a belt conveyor, including a first deviation switch, a second deviation switch, a controller 3 and an actuator 2. A first deviation switch is provided on one side of the belt conveyor, and a second deviation switch is provided on the other side of the belt conveyor. The first deviation switch and the second deviation switch are symmetrically arranged and communicatively connected. The first deviation switch and the second deviation switch can respectively detect the corresponding offset amounts of the belt on the near side of the belt conveyor. Inside the first deviation switch and the second deviation switch, there are a controller 3 and an actuator 2. The controller 3 can obtain the offset amounts detected by the first deviation switch and the second deviation switch, that is, obtain the corresponding offset amounts on both sides of the belt. The controller 3 can compare the offset amounts on both sides of the belt to obtain the actual deviation direction of the belt. Based on the actual deviation direction of the belt, the actuator 2 issues a corresponding control signal. The actuator 2 receives the control signal and issues a corresponding action signal based on the control signal, so that the belt starts or stops.

[0030] Furthermore, the actuator 2 controls the start and stop actions of the belt by sending the action signal to the PLC or the control cabinet.

[0031] In some embodiments, both the first deviation switch and the second deviation switch include an infrared detector 1, a data wire 8, and a power supply module. The two infrared detectors 1 are respectively installed on both sides of the belt conveyor through mounting brackets 9. The infrared detector 1 is connected to a power supply module, and the power supply module is used to supply power to the infrared detector 1. The infrared detector 1 is connected to the corresponding controller 3 through the data wire 8, and the controller 3 is provided with a communication interface 6.

[0032] Furthermore, the laser head 4 of the infrared detector 1 is vertically oriented towards the edge side of the belt, so that the infrared detector 1 can detect the distance from its laser head 4 to the belt edge.

[0033] Furthermore, the communication interface 6 is an RS485 data interface. The communication interface 6 of the controller 3 in the first deviation switch is connected to the communication interface 6 of the controller 3 in the second deviation switch through a communication twisted pair 7.

[0034] Furthermore, the power supply module uses a solar cell 10.

[0035] Furthermore, both the first deviation switch and the second deviation switch are provided with a protective housing 5. The protective housing 5 can protect the infrared detector 1, the controller 3 and the actuator 2, and play a certain role in dust and water protection to ensure the detection accuracy.

[0036] At present, there is a lack of unified industry standards for the selection and installation of belt conveyor protection devices, and their usage effects are often not ideal. However, this device can automatically determine the position of belt deviation by comparing the offset amounts on both sides of the belt, improving the judgment accuracy of belt deviation, greatly reducing the misoperation of deviation switches, and helping to improve the reliability and effectiveness of protection.

[0037] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention shall be covered within the protection scope of the present invention.
