Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation, and particularly to a material guiding trough device. Background Art

[0002] A material guiding trough is a trough-shaped structure for transporting materials and is one of the common components of a material transportation system. The material guiding trough is often arranged at the receiving place of a belt conveyor, which can concentrate the falling materials to the middle of the conveyor belt before they reach the belt speed of the conveyor belt and limit the materials to prevent them from spilling out. In different application scenarios, the specifications, quantities, and transportation speeds of the materials are different. Keeping an appropriate material flow rate on the material guiding trough can not only reduce the occurrence of phenomena such as material spilling from both sides and blockage, but also play a crucial role in ensuring the service life and safety of the equipment.

[0003] In the prior art, the movement of materials is usually restricted by the contact between the material gathering device and the materials, or the distance between the material guiding trough and the conveyor belt is adjusted to adjust the movement state of the materials.

[0034] In industrial production and transportation, large pieces of materials frequently fall off when the belt conveyor transfers materials, seriously endangering production safety and continuity. To solve the above problems, the present invention proposes an anti-blocking and adjustable guiding trough device based on fiber optic vibration monitoring. The material gathering module of the guiding trough can control the material flow to gather towards the center, shape and maintain the optimal material pile form, prevent the materials from falling off after breaking away from the restraint of the guiding trough, and use vibration measuring optical fibers to synchronously and real-time monitor the guiding trough. Through vibration signal acquisition, identification and judgment, the blocking situation in the material gathering area is determined. The material gathering module can flexibly adjust the size of the material pile according to the actual situation of the material flow and the monitoring results to prevent the guiding trough from being blocked. The implementation of the present invention can effectively control the material form, ensure that the material flow maintains the optimal material pile form when passing through the guiding trough, effectively reduce the spillage during the material transportation process, can real-time monitor the blocking of the guiding trough and make timely adjustment responses, ensure the continuity and safety of the material transportation, and avoid the reduction of production efficiency and the increase of safety risks caused by material spillage and blockage. In view of the above problems, an embodiment of the present invention provides a guiding trough device, as Figures 1 to 4 shown, including:

[0035] A guiding trough body, including a material gathering area and a material stabilizing area, the material gathering area is arranged upstream of the material stabilizing area and is communicated with the material stabilizing area, and the discharge port of the material gathering area is connected to the feed port of the material stabilizing area;

[0036] A material flow state monitoring module, used to obtain the material flow state parameters entering the material gathering area, and the material flow state parameters include the material flow size;

[0037] A material gathering module 6, movably arranged in the material gathering area, used to adjust the material flow width in the material gathering area and the size of the discharge port of the material gathering area;

[0038] A material stabilizing module, movably arranged in the material stabilizing area, used to adjust the material flow width in the material stabilizing area;

[0039] A controller, electrically connected to the material flow size detection sensor, the material gathering module 6, and the material stabilizing module, is configured to generate a material gathering module 6 control signal and / or a material stabilizing module control signal according to the material flow size. The material stabilizing module control signal is used to control the operation of the material gathering module 6, and the material stabilizing module control signal is used to control the operation of the material stabilizing module.

[0040] Among them, the material guiding trough body refers to the main structure of the material guiding trough device, which is used to accommodate and guide the flow of materials. The material gathering area and the material stabilizing area respectively refer to the areas in the material guiding trough body for realizing the gathering of the material flow and the stabilization of the material flow. One or more material gathering areas and / or material stabilizing areas can be respectively provided on the material guiding trough body. The material gathering module 6 and the material stabilizing module can include movable parts, transmission mechanisms, and power sources. The movable parts can be structures such as push rods or plates. The transmission mechanisms can include motors, lead screws, or slide rail sliders. The power sources can be power supplies, cylinders, or hydraulic cylinders, etc. When the material enters the material gathering area, the movable parts of the material gathering module 6 push the material, causing the scattered material to gather towards the center of the material guiding trough. At the same time, the size of the outlet of the material gathering area is adjusted to control the flow rate and speed of the material entering the material stabilizing area. The material stabilizing area pushes the material through the movable parts in the material stabilizing module, making the material flow more uniform and stable during the conveying process, reducing the fluctuation and deviation of the material flow. The material flow state detection module is used to obtain the state parameters of the material flow entering the material gathering area in real time, and can include one or a combination of several of a laser ranging sensor, an ultrasonic sensor, an infrared sensor, or a vision sensor. The material flow state parameters include, but are not limited to, parameters such as the category, weight, specification size, flow rate, width, and height of the material flow. The controller can include components such as a computer. When the controller determines that a material gathering operation or a material stabilizing operation is required based on the material flow state parameters, it generates a material gathering module 6 control signal or a material stabilizing module control signal. The control signal can include the operation information that the material gathering module 6 or the material stabilizing module needs to execute, such as the moving direction, angle, distance, and speed, etc. The corresponding drive source acts according to the control signal, driving the movable parts to move through the transmission mechanism, realizing the guidance and arrangement of the material.

[0041] For the above-mentioned material guiding trough device, the material flow state detection module obtains state parameters such as the material flow size of the material entering the material gathering area. The controller generates control signals according to these parameters to adjust the material gathering module 6 and the material stabilizing module, enabling the material guiding trough device to respond in a timely manner to changes in the material flow size and ensuring the stable conveying of the material flow. The material gathering module 6 is movably arranged in the material gathering area. By adjusting the width of the material flow and the size of the outlet in the material gathering area, the scattered material flow can be effectively gathered, avoiding the scattering or overflow of the material during the conveying process. The material stabilizing module adjusts the width of the material flow, which helps to further stabilize the conveying state of the material flow, reducing the fluctuation of the material flow and the occurrence of material blockage. By automatically controlling the actions of the material gathering module 6 and the material stabilizing module according to the state parameters of the material flow by the controller, the position of the material in the material guiding trough can be flexibly adjusted according to the material form, making the conveying process of the material smoother and improving the production efficiency.

[0042] In an exemplary embodiment, a material blockage detection module is further included. The material blockage detection module is electrically connected to the controller and is used to collect the vibration signal of the material guiding trough body. The controller is further used to judge whether material blockage occurs in the material guiding trough according to the vibration signal, and generate the control signal of the material gathering module 6 and / or the control signal of the material stabilizing module when material blockage occurs. Among them, the material blockage detection module may include one or more of a pressure detection unit, a material level detection unit, a flow rate detection unit or a vibration detection unit. When the material in the material guiding trough flows normally, the pressure, flow rate, vibration and height will all be within a relatively stable range. When material blockage occurs, the above parameters will change. For example, when material blockage occurs, the accumulation and flow state of the material change, which will cause the vibration signal to change. Whether material blockage occurs can be judged by analyzing the characteristics such as the frequency and amplitude of the vibration signal. When the frequency of the vibration signal decreases significantly, the amplitude increases and the fluctuation intensifies, and it lasts for a period of time, it can be judged that material blockage has occurred. Whether material blockage occurs in the material guiding trough can be judged by setting thresholds and the duration of each parameter exceeding the threshold, or whether material blockage occurs can be comprehensively judged according to the signals collected by multiple detection units to improve the accuracy of judgment.

[0043] In an exemplary embodiment, the material blockage detection module includes a distributed vibration measurement optical fiber 3, and the distributed vibration measurement optical fiber 3 is uniformly laid on the outer wall of the material guiding trough body. Distributed optical fiber refers to using the optical fiber as a sensing medium, detecting and analyzing the optical signal transmitted in the optical fiber, and measuring multiple points or continuous regions along the length direction of the optical fiber. The distributed vibration measurement optical fiber 3 can be uniformly laid on the outer wall of the material guiding trough body in a spiral, linear or grid-like manner. Both ends of the optical fiber are connected to an optical fiber vibration demodulation device, and the optical fiber vibration demodulation device coordinates the optical signal transmitted in the optical fiber to extract the vibration signal for judging whether there is material blockage.

[0044] In an exemplary embodiment, the distributed vibration measurement optical fiber 3 includes a vibration measurement optical fiber 302 and a plurality of optical fiber sensitization structures 301. The vibration measurement optical fiber 302 is laid on the outer side wall of the material guiding trough body and is parallel to the extending direction of the material guiding trough. The plurality of optical fiber sensitization structures 301 are uniformly distributed on the vibration measurement optical fiber 302 and are used to enhance the intensity of the optical signal transmitted by the vibration measurement optical fiber 302. Among them, the vibration measurement optical fiber 302 is the main body of the distributed vibration measurement optical fiber 3 and can be laid on the outer side wall of the material guiding trough along the extending direction of the material guiding trough as shown in Figure 1 . The optical fiber sensitization structure 301 may be an optical fiber grating integrated with the vibration measurement optical fiber 302. The optical fiber grating is very sensitive to temperature and stress changes and can be used to improve the sensitivity of the distributed vibration measurement optical fiber 3.

[0045] In an exemplary embodiment, as Figure 2 shown, the material gathering module 6 includes a material gathering plate 601 and a material gathering push rod 602. The first end of the material gathering plate 601 is rotatably connected to the inner side wall of the material guiding groove body, and the second end is rotatably connected to the material gathering push rod 602. The movement direction of the material gathering push rod 602 forms an angle with the extending direction of the material guiding groove body. The material gathering push rod 602 is used to drive the second end of the material gathering plate 601 to rotate around the first end. By pushing the second end of the material gathering plate 601 to rotate around the first end, the relative position of the first end and the side wall of the material guiding groove remains unchanged, and the distance between the second end and the material guiding groove changes, thereby changing the cross-sectional size of the material passing through. When the second end moves away from the side wall of the material guiding groove, the scattered materials can be pushed towards the middle of the material guiding groove to achieve the gathering of the materials, and at the same time, the discharge port of the material gathering area is reduced. When the second end moves towards the side wall of the material guiding groove, the discharge port of the material gathering area will be increased.

[0046] In an exemplary embodiment, the width of the material gathering plate 601 gradually decreases from the first end to the second end. In this way, the feeding port size of the material gathering area is larger, which is beneficial to the smooth entry of materials into the material gathering area. The material gathering plate 601 can be a triangle as Figure 2 shown, or a trapezoid or other shapes.

[0047] In an exemplary embodiment, the material stabilizing mechanism includes a material stabilizing plate 604, a first material stabilizing push rod 603, and a second material stabilizing push rod 605. The first end of the material stabilizing plate 604 is rotatably connected to the first material stabilizing push rod 603, and the second end is rotatably connected to the second material stabilizing push rod 605. The first material stabilizing push rod 603 and the second material stabilizing push rod 605 are electrically connected to the controller and are used to drive the material gathering plate 601 to approach or move away from the material flow. Among them, the material stabilizing plate 604 can be a rectangle as Figure 2 shown, or other shapes. The contact surface of the material stabilizing plate 604 is parallel to the running direction of the material flow. The first material stabilizing push rod 603 and the second material stabilizing push rod 605 are arranged in parallel. When the first material stabilizing push rod 603 and the second material stabilizing push rod 605 run synchronously, the distance between the material stabilizing plate 604 and the material flow can be adjusted, and at the same time, the direction of the material flow will not be changed, thereby ensuring the stability of the material flow.

[0048] In an exemplary embodiment, the material guiding groove device includes a plurality of material gathering areas and a plurality of material stabilizing areas, and the plurality of material gathering areas and the plurality of material stabilizing areas are alternately distributed on the material guiding groove body. The alternating distribution of the material gathering areas and the material stabilizing areas helps to maintain the uniform distribution and smooth transportation of the materials.

[0049] In an exemplary embodiment, the material guiding groove device includes a plurality of the material gathering modules 6 and a plurality of the material stabilizing modules, and the material gathering modules 6 and the material stabilizing modules are arranged on both sides of the material guiding groove body. AsFigure 3 As shown, the material gathering module 6 and the material stabilizing module can be arranged adjacent to each other, and the material gathering module 6 and the material stabilizing module can be staggered on both sides along the material flow direction. When the flow rate is large, the material flow can be gradually stabilized through the coordinated action of multiple material gathering modules 6 and multiple material stabilizing modules.

[0050] In an exemplary embodiment, the guiding trough body includes a bottom plate, side plates 4 and a top plate 5. Among them, the side plates 4 are arranged on both sides of the bottom plate and fixedly connected to the side plates 4, the top plate 5 is detachably connected to the side plates 4, and dust-proof curtains 7 are arranged at both ends of the top plate 5.

[0051] The present invention provides an anti-blocking adjustable guiding trough device based on optical fiber vibration measurement and monitoring, which is characterized by devices such as a material gathering module, a distributed vibration measurement optical fiber, a guiding trough side plate, a guiding trough top plate, and a guiding trough dust-proof curtain. The guiding trough side plate 4, the guiding trough top plate 5, and the guiding trough dust-proof curtain 7 are firmly connected by bolts to construct a sealed frame structure of the guiding trough. The support frame 8 is fixedly connected to the guiding trough side plate 4 to increase the structural strength of the guiding trough and reinforce the material gathering area, ensuring the stability and reliability of the device.

[0052] The distributed vibration measurement optical fiber 3 includes an optical fiber sensitization structure 301 and a vibration measurement optical fiber 302. The vibration measurement optical fiber 302 is laid outside the guiding trough side plate 4. When laying the optical fiber, the bending radius of the optical fiber should be avoided being too small, otherwise it will have an adverse impact on its mechanical properties and optical characteristics, affecting the accuracy and stability of the monitoring data. Optical fiber sensitizers 301 are arranged at specific interval positions to enhance the induction sensitivity and response speed of the vibration measurement optical fiber 302 to vibration signals, and improve the range and accuracy of optical fiber vibration measurement.

[0053] The material gathering module 6 includes a material gathering plate 601, a material gathering push rod 602, a material stabilizing push rod 603, and a material stabilizing plate 604. The material gathering plate 601 is connected in a hinged manner inside the guiding trough side plate 4 and is connected to the material gathering push rod 602 through a ball joint; the material gathering push rod 602 is respectively connected to the material gathering plate 601 and the guiding trough side plate 4 in a hinged manner. The material gathering push rod 602 can control the material gathering plate 601 to adjust the opening size of the material gathering area to adapt to different material flow conditions and transportation requirements, effectively preventing material scattering; one end of the material stabilizing push rod 603 is hinged to the material stabilizing plate 604, and the other end is hinged to the guiding trough side plate 4. The material stabilizing plate 604 is respectively connected to the material stabilizing push rod 603 and the guiding trough side plate 4. The material stabilizing push rod 603 can control the material stabilizing plate 604 to adjust the opening size of the material stabilizing area to ensure that the material flow maintains a stable and orderly flow state in the guiding trough, improving the efficiency and safety of material transportation, and preventing phenomena such as material blockage caused by material flow fluctuations.

[0054] The specific steps of the anti-blocking adjustable guiding trough device based on optical fiber vibration measurement and monitoring are as follows:

[0055] Step 1: The material gathering module 6 is installed inside the side plate 4 of the material guiding trough. According to the material flow size, control the material gathering push rod 602 and the material stabilizing push rod 603 to adjust the opening sizes of the material gathering area and the material stabilizing area, so that the materials converge towards the center in the material gathering area, and the material stabilizing area maintains the best shape of the materials.

[0056] Step 2: Lay the optical fiber sensitizing structure 301 and the vibration measuring optical fiber 302 outside the side plate 4 of the material guiding trough to monitor the blockage of the material guiding trough, collect the vibration signals of the material guiding trough and transmit them to the monitoring host. After signal processing and determination, if blockage occurs, timely control the material gathering push rod 602 and the material stabilizing push rod 603 to adjust the material state to solve the blockage problem.

[0057] The anti-blocking adjustable material guiding trough provided by an embodiment of the present invention can change the shape of the materials through the material gathering module, so that the material flow maintains the best material pile shape when passing through the material guiding trough, avoiding the situation of spilling after the materials leave the material guiding trough. It has a real-time monitoring function and monitors the material guiding trough in real time. When blockage occurs, it can control the material gathering module to adjust the opening size to improve the material shape, so that the materials can pass smoothly and prevent the material guiding trough from being blocked by materials.

[0058] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.
