Description

Technical Field

[0001] The utility model relates to the technical field of tobacco conveyor cleaning, in particular to a cleaning device for a vibrating trough of a conveyor. Background Art

[0002] At present, in the process of tobacco product processing, after the tobacco leaves go through the leaf rewetting process, the tobacco leaves need to be placed into the vibrating trough at the entrance of the tobacco conveyor, so as to facilitate the transportation of the tobacco leaves to the next process. Among them, due to the viscosity and static electricity of the tobacco leaves themselves, the tobacco leaves are prone to entanglement or overlap with each other, and the tobacco leaves are easy to accumulate in the vibrating trough. Therefore, it is necessary for operators to clean the vibrating trough in time to prevent the accumulation of materials from causing blockage at the entrance, so as to avoid the risk of production line shutdown and equipment failure.

[0003] However, during the manual cleaning process, operators need to work at heights, which is prone to certain safety hazards. Moreover, the manual cleaning workload is large, and there is a risk that the broom will fall into the vibrating trough due to operator fatigue, increasing the risk of equipment failure. Summary of the Utility Model

[0004] Aiming at the above deficiencies, the utility model provides a cleaning device for a vibrating trough of a conveyor, which can monitor the accumulation of materials in the vibrating trough in real time and achieve the effect of automatically cleaning the vibrating trough by a multi-axis robotic arm, saving manpower and ensuring the continuity of production.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0007] The conveyor vibrating trough cleaning device according to the embodiment of the present utility model has at least the following beneficial effects: during use, when the production of each batch of tobacco ends and the stacking height of the material is greater than the set height, the detection component feeds back a signal to the control module, and the control module controls the multi-axis robotic arm to enter the preparation stage of the cleaning work. During this process, the image acquisition component first captures an image of the vibrating trough, and then the control module uses the neural network vision algorithm to detect the position of the vibrating trough in the image. The control module obtains the coordinates of the vibrating trough and calculates the initial path of the multi-axis robotic arm. Finally, after completing the path planning, the multi-axis robotic arm transports the brush component to the corresponding position for cleaning work. During the operation of the multi-axis robotic arm, the proximity sensor is used to determine whether there are obstacles on the path. If there are obstacles, the control module re-plans the path, so that the multi-axis robotic arm adjusts the cleaning path of the brush component according to the new path plan. Through the above structure, the accumulation of materials in the vibrating trough is monitored in real time, and the effect of automatically cleaning the vibrating trough by the multi-axis robotic arm is achieved, saving manpower and ensuring the continuity of production.

[0026] See Figure 1 and Figure 2 , a conveyor vibrating trough cleaning device, comprising: a frame 100, a multi-axis robotic arm 300 and a control module. The frame 100 is used to be erected on the outer periphery of the vibrating trough 200. The frame 100 is provided with a detection component and an image acquisition component. The detection component is used to detect the height of the material accumulation in the vibrating trough 200, and the image acquisition component is used to take pictures towards the vibrating trough 200; the multi-axis robotic arm 300 is used to be arranged on the side of the vibrating trough 200. A brush component 310 is arranged at the end of the multi-axis robotic arm 300, and a proximity sensor 320 is arranged on the multi-axis robotic arm 300. The proximity sensor 320 is used to detect obstacles to form an electrical signal; the control module is electrically connected to the detection component, the image acquisition component, the multi-axis robotic arm 300 and the proximity sensor 320; wherein, when the detection component detects that the height of the material accumulation is greater than the set height, the control module controls the multi-axis robotic arm 300 to perform cleaning work, and based on the image generated by the image acquisition component and the signal generated by the proximity sensor 320, the control module adjusts the movement path of the multi-axis robotic arm 300 to clean the vibrating trough 200.

[0027] For the conveyor vibrating trough cleaning device with the above structure, during use, when the production of each batch of tobacco ends and the accumulated height of the material is greater than the set height, the detection component feeds back a signal to the control module, and the control module controls the multi-axis robotic arm 300 to enter the preparation stage of the cleaning operation. During this process, the image acquisition component first captures an image of the vibrating trough 200, and then the control module uses the neural network vision algorithm to detect the position of the vibrating trough 200 in the image. The control module obtains the coordinates of the vibrating trough 200 and calculates the initial path of the multi-axis robotic arm 300. Finally, after completing the path planning, the multi-axis robotic arm 300 transports the brush component 310 to the corresponding position for the cleaning operation. During the operation of the multi-axis robotic arm 300, the proximity sensor 320 determines whether there are obstacles on the path. If there are obstacles, the control module re-plans the path, so that the multi-axis robotic arm 300 adjusts the cleaning path of the brush component 310 according to the new path planning. Through the above structure, the accumulation of materials in the vibrating trough 200 is monitored in real time, and the effect of automatically cleaning the vibrating trough 200 by the multi-axis robotic arm 300 is achieved, saving manpower and ensuring the continuity of production.

[0028] It can be understood that the neural network vision algorithm performs target positioning analysis on the image of the vibrating trough 200, generates the X and Y plane coordinates of the vibrating trough 200, and combines the monocular ranging model to obtain the Z coordinate of the depth of the vibrating trough 200, so as to generate. After triggering the alarm, the system adjusts the preset path points according to the three-dimensional coordinates detected by the camera. Among them, the multi-axis robotic arm 300 uses an existing five-axis robotic arm, and the five-axis robotic arm is arranged on the mounting base 340, and the mounting base 340 is located on one side of the vibrating trough 200, so as to realize the movement of the brush component 310 through the five-axis robotic arm.

[0029] Furthermore, the proximity sensor 320 is a capacitive sensor. When the brush component 310 encounters an obstacle, the capacitive sensor generates a detection signal that is fed back to the control module. Specifically, the capacitive sensor is an existing sensor that converts the change of the measured non-electrical quantity into the change of capacitance, and can realize non-contact measurement of the pole distance change caused by force, pressure or vibration, which is beneficial to improving the response efficiency of the multi-axis robotic arm 300.

[0030] See Figure 1 and Figure 2, Further, the control module includes a visual control panel 120. The image acquisition component includes an industrial camera 110 and an image processor that are electrically connected. The control panel 120 is electrically connected to the image processor, and the image processor is used to identify the material image collected by the industrial camera 110 and generate a path of the coordinate system. Specifically, the industrial camera 110 converts the captured target into an image signal and transmits it to the image processor for analysis and processing. Finally, information such as the position distribution of the captured target is obtained, which is beneficial to improving the accuracy of planning the path of the multi-axis robotic arm 300 and has high efficiency. Among them, the control panel 120 can display in real time information such as the image taken by the camera, the situation of material accumulation, or the coordinates of the target.

[0031] Further, the detection component includes a photoelectric sensor provided on the vibrating trough 200. The photoelectric sensor is electrically connected to the control module, and the photoelectric sensor is used to detect the height of material accumulation in the vibrating trough 200. Specifically, after the height of material accumulation exceeds the set height, the material directly causes a change in the light quantity of the photoelectric sensor to form a detection signal, enabling the control module to promptly operate the multi-axis robotic arm 300 for cleaning. The response is fast and reliable, ensuring the continuity of production. It can be understood that the detection component can adopt a transmissive switch, and the specific structure will not be elaborated.

[0032] Further, it further includes an alarm module electrically connected to the control module. When the height of material accumulation is greater than the set height, the control module controls the alarm module to generate an alarm signal, thereby generating a prompt signal for the operator that the multi-axis robotic arm 300 is about to operate, facilitating the operator to stay away.

[0033] Further, the alarm module includes at least one of an indicator light, a buzzer, and an audible and visual alarm. It can be understood that the indicator light is an indicator light that can change among three colors: red and green. When the indicator light shows red, the multi-axis robotic arm 300 is in the cleaning working state. When the indicator light shows green, the multi-axis robotic arm 300 is in the non-working state. Through the changing colors of the indicator light, it is beneficial for the operator to perform different operations according to the changing colors of the indicator light. It can be understood that the indicator light can also cooperate with the sound generated by the buzzer, which is beneficial to prompting the operator through optical and acoustic signals.

[0034] Further, the control module includes a PLC programmable controller, thereby realizing the industrial control of the multi-axis robotic arm 300.

[0035] Further, the brush component 310 includes a mounting plate rotatably provided on the multi-axis robotic arm 300. The mounting plate is connected to a motor that drives it to rotate. The motor is electrically connected to the control module. A brush is provided on the side of the mounting plate away from the multi-axis robotic arm 300. Thus, by driving the mounting plate to rotate through the motor, it is beneficial for the brush to perform rotary cleaning, thereby improving the cleaning effect of the vibrating trough 200.

[0036] SeeFigure 1 and Figure 2 , further, a torque sensor 330 is installed between the end of the multi-axis robotic arm 300 and the brush assembly 310, and the torque sensor 330 is electrically connected to the control module. Specifically, the torque sensor 330 is used to detect the torque of the contact between the brush and the vibrating trough 200, and the control module adjusts the cleaning action of the multi-axis robotic arm 300 based on the torque change.

[0037] Further, a plurality of shock pads are further included, and the shock pads are arranged at the corresponding joints of the multi-axis robotic arm 300, which is beneficial to reducing the vibration transmission between the joints of the multi-axis robotic arm 300.

[0038] 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 to be within the scope described in this specification.

[0039] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
