Description

Technical Field

[0001] This utility model relates to the field of sorting machines, and in particular to a sorting device for sorting machines. Background Technology

[0002] Sorting machines are mechanical devices used for automatically sorting and distributing goods, and are widely used in industries such as logistics, warehousing, postal services, and manufacturing. They utilize technologies such as conveyor belts, scanning and recognition, robotic arms, or air blowing to quickly and accurately sort items of different types, specifications, or destinations to designated locations according to preset rules, thereby significantly improving sorting efficiency, reducing labor costs, and optimizing logistics operations.

[0003] Existing sorting machines require a preliminary scan using a sorting camera before sorting, which is then used by the subsequent production line for sorting operations. However, traditional sorting machines mostly use cameras set at a fixed angle. During this initial scan, the camera cannot dynamically adjust its angle to accommodate objects of different shapes, sizes, and materials, resulting in a limited scanning field of view and blind spots. When encountering irregularly shaped objects, reflective surfaces, or packaging with complex textures, the fixed-angle camera struggles to achieve optimal imaging, easily leading to problems such as blurry images, light reflection interference, or obstruction of key information. This severely impacts the accuracy of barcode recognition, size measurement, and item classification. Furthermore, the inability to adjust the height prevents optimization of the distance between the camera and objects of different heights, resulting in focal length mismatch, further reducing image clarity and scanning success rate, and increasing the probability of missorting and duplicate scanning.

[0004] Therefore, a sorting device for a sorting machine is proposed to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a sorting device for a sorting machine, which has the advantages of precise height adjustment and rapid angle tilt adjustment.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A sorting device for a sorting machine, comprising a sorting machine conveyor belt mechanism; A positioning plate is mounted on the sorting machine conveyor belt mechanism. A height adjustment component is mounted on the upper surface of the positioning plate. A tilt adjustment mechanism is mounted on the height adjustment component. A vision sorting camera is mounted on the tilt adjustment mechanism. The height adjustment component includes a vertical plate disposed on the upper surface of the positioning plate, a vertical plate mounted on the side of the vertical plate, and two sets of vertical linear guide rails arranged parallel to the vertical direction on the side of the vertical plate. Guide rail sliders are slidably disposed on both vertical linear guide rails, and an installation plate is mounted on the side of both guide rail sliders. The tilt adjustment mechanism includes two support seats disposed on the side of the mounting plate, a side plate is mounted between the two support seats, the side plate is tilted and two positioning seats are disposed parallel to its side, and two tilted linear guide rails are disposed between the two positioning seats; a slider seat is slidably fitted on the two tilted linear guide rails.

[0007] Furthermore, the visual sorting camera is detachably mounted on the side of the slider base.

[0008] Furthermore, the tilt adjustment mechanism also includes a linear guide cylinder disposed on one side of one of the support seats.

[0009] Furthermore, the output end of the linear guide cylinder passes through one of the positioning seats and extends to connect with the side of the vision sorting camera.

[0010] Furthermore, a linear push rod cylinder is installed on the top, and the output end of the linear push rod cylinder extends and connects to the mounting plate.

[0011] Furthermore, both the slider base and the vision sorting camera are provided with corresponding bolt holes, and the vision sorting camera is threaded with bolts and is detachably assembled to the side of the slider base through the bolts.

[0012] In summary, this utility model has the following beneficial effects: This sorting device achieves flexible spatial adjustment of the vision sorting camera by rationally arranging positioning plates, height adjustment components, and tilt adjustment mechanisms on the sorting machine's conveyor belt mechanism. The height adjustment component utilizes upright plates and vertical plates in conjunction with two sets of vertical linear guides and guide rail sliders to ensure the mounting plate can smoothly adjust its height, improving the camera's adaptability to materials of different heights. The tilt adjustment mechanism, through a combination of support base, side plates, positioning base, and tilting linear guides, allows the slider seat carrying the vision sorting camera to slide precisely along the tilt direction, ensuring accurate positioning of the camera's viewing angle and shooting angle, thereby enhancing the accuracy and efficiency of sorting and identification.

[0013] This device utilizes two pneumatic drive structures: linear guide rod cylinders and linear push rod cylinders, used for the automatic adjustment of the tilt adjustment mechanism and the height adjustment component, respectively. This significantly improves the automation level and response speed of the adjustment, while reducing the complexity and error of manual adjustment. Simultaneously, the vision sorting camera is detachably mounted on the side of the slider seat using bolts, facilitating maintenance and replacement and improving the equipment's flexibility and ease of maintenance. The overall structural layout is scientifically sound and reasonable, ensuring both the stability and accuracy of the adjustment mechanism while enhancing the system's intelligence and adaptability, significantly optimizing the sorting function and operational efficiency of the sorting machine.

[0018] First embodiment; Reference Figure 1-4 As shown, a sorting device for a sorting machine is provided in a preferred embodiment of the present invention, including a sorting machine conveyor belt mechanism 1; A positioning plate is installed on the conveyor belt mechanism 1 of the sorting machine. A height adjustment component 2 is installed on the upper surface of the positioning plate. A tilt adjustment mechanism 3 is installed on the height adjustment component 2. A vision sorting camera 4 is installed on the tilt adjustment mechanism 3. The height adjustment component 2 includes a vertical plate 21 set on the upper surface of the positioning plate, a vertical plate 22 installed on the side of the vertical plate 21, two sets of vertical linear guide rails 23 arranged parallel to the vertical direction on the side of the vertical plate 22, guide rail sliders 24 slidably arranged on both vertical linear guide rails 23, and a mounting plate 25 is installed on the side of both guide rail sliders 24. The tilt adjustment mechanism 3 includes two support seats 31 disposed on the side of the mounting plate 25. A side plate 32 is assembled between the two support seats 31. The side plate 32 is tilted and two positioning seats 33 are arranged parallel to its side. Two tilted linear guide rails 34 are disposed between the two positioning seats 33.

[0019] In this embodiment, the sorting machine conveyor belt mechanism 1 is based on which a positioning plate is innovatively installed. A height adjustment component 2 is fixedly installed on the upper surface of the positioning plate. The height adjustment component 2 is further equipped with a tilt adjustment mechanism 3. A vision sorting camera 4 is installed on the tilt adjustment mechanism 3, forming a complete three-dimensional adjustment system. The height adjustment component 2 includes a vertical plate 21 located on the upper surface of the positioning plate. A vertical plate 22 is horizontally mounted on its side. Two sets of vertical linear guide rails 23 are arranged parallel to each other in the vertical direction on the vertical plate 22. Guide rail sliders 24 are slidably mounted on the two sets of vertical linear guide rails 23. The sides of the guide rail sliders 24 are supported and connected to the mounting plate 25 to achieve precise adjustment in the height direction. The tilt adjustment mechanism 3 is installed on the side of the mounting plate 25 and includes two support seats 31 and a side plate 32 inclined between the two support seats. Two positioning seats 33 are arranged parallel to each other on the side of the side plate 32. Two inclined linear guide rails 34 are mounted between the positioning seats 33. A slider seat 35 is embedded in the inclined linear guide rail 34 to achieve control and adjustment of the tilt angle of the vision sorting camera 4. This structure, through dual adjustment of height and tilt, achieves the optimal viewing angle and appropriate distance for items in the visual sorting system, which helps to improve recognition accuracy and speed.

[0020] Second embodiment; Reference Figure 2-3 As shown, the visual sorting camera 4 is detachably mounted on the side of the slider base 35.

[0021] In this embodiment, the visual sorting camera 4 is fixedly connected to the side of the slider seat 35, and also has the function of convenient and quick disassembly. This design facilitates the quick replacement of the camera during equipment maintenance or upgrades without disassembling the entire tilt adjustment mechanism 3, greatly improving the convenience of equipment maintenance and operational flexibility, enabling the sorting system to adapt to various models and functions of cameras to meet the needs of different sorting tasks.

[0022] Third embodiment; Reference Figure 2-3As shown, the tilt adjustment mechanism 3 also includes a linear guide cylinder 36 disposed on one side of one of the support seats 31.

[0023] In this embodiment, the cylinder is mounted on one side of one of the support seats 31, forming an automated drive unit for adjusting the tilt angle of the vision sorting camera 4. The introduction of the linear guide cylinder 36 replaces the traditional manual adjustment method, enabling precise and rapid movement of the slider seat 35 along the tilted linear guide rail 34 via the extension and retraction of the cylinder piston rod, thus achieving automatic and real-time adjustment of the camera angle. This automated structure not only improves the accuracy and response speed of angle adjustment but also reduces the labor intensity of operators and enhances the intelligent control level of the sorting system.

[0024] Fourth embodiment; Reference Figure 2-3 As shown, the output end of the linear guide cylinder 36 passes through one of the positioning seats 33 and extends to connect with the side of the vision sorting camera 4.

[0025] In this embodiment, the output end of the linear guide cylinder 36 passes through one of the positioning seats 33 and is directly connected to the side of the vision sorting camera 4. This design optimizes the power transmission path, ensuring that the cylinder driving force can act on the camera efficiently and stably, maintaining smooth and stable adjustment movements. The through-type connection eliminates frictional resistance and gaps caused by redundant mechanical connection mechanisms, achieving high rigidity and high precision of the tilt adjustment mechanism, and improving the overall reliability and performance of the vision system.

[0026] Fifth embodiment; Reference Figure 4 As shown, a linear push rod cylinder 26 is mounted on the top of 22, and the output end of the linear push rod cylinder 26 extends and connects to the mounting plate 25.

[0027] In this embodiment, a linear push rod cylinder 26 is installed at the top of the vertical plate 22, with the cylinder output end extending and connected to the mounting plate 25. The lifting and lowering movement of the entire height adjustment assembly 2 is achieved through the extension and retraction of the cylinder's piston rod. This pneumatic drive scheme replaces the traditional manual adjustment, realizing automatic height adjustment. It can flexibly adjust the working height of the vision sorting camera 4 according to sensor or control system commands, thereby optimizing the sorting equipment's adaptability to items of different sizes and stacks. This not only improves the efficiency and accuracy of sorting operations but also enhances the equipment's intelligence level.

[0028] Sixth embodiment; Reference Figure 2-3 As shown, both the slider base 35 and the vision sorting camera 4 have corresponding bolt holes. The vision sorting camera 4 is threaded with bolts and is detachably mounted to the side of the slider base 35 by means of bolts.

[0029] In this embodiment, both the slider base 35 and the camera 4 are provided with matching bolt holes. The camera side is secured to the side of the slider base 35 via threaded bolts passing through the holes. This connection method allows operators to quickly disassemble the vision sorting camera 4 by loosening and unscrewing the bolts. This standardized fastening and disassembly design ensures the stability and safety of the equipment during operation and provides convenient conditions for equipment maintenance and replacement, improving the maintainability and long-term reliability of the overall system.

[0030] Specific implementation process Step 1: Before the sorting operation begins, based on the height characteristics of the objects to be sorted and the stacking status of the items on the conveyor belt, the linear pusher cylinder 26, located at the top of the vertical plate 22, is activated. The output end of the linear pusher cylinder 26 extends and connects to the mounting plate 25. The extension and retraction of the cylinder piston rod drives the mounting plate 25 to move up and down along two sets of vertical linear guide rails 23 parallel to the side of the vertical plate 22. The guide rail sliders 24, which are slidably mounted on the two vertical linear guide rails 23, drive the mounting plate 25 to achieve precise vertical displacement under the thrust of the cylinder, thereby adjusting the overall height position of the entire tilt adjustment mechanism 3 and the vision sorting camera 4. The vertical plate 22 is installed on the side of the upright plate 21, which is fixed to the upper surface of the positioning plate, forming a stable support structure to ensure a smooth and reliable height adjustment process. The operator or the automatic control system can precisely control the extension of the linear pusher cylinder 26 based on the item height information fed back by the sensor, so that the vision sorting camera 4 maintains the optimal scanning distance and focal length range with the sorted object, effectively improving the clarity of image acquisition and recognition accuracy. Step 2: After height adjustment, for sorting objects of different shapes and orientations, activate the linear guide cylinder 36 located on one side of one of the support seats 31 in the tilt adjustment mechanism 3. The output end of the linear guide cylinder 36 passes through one of the positioning seats 33 and extends to connect with the side of the vision sorting camera 4. The side plate 32, which is assembled between the two support seats 31, is inclined. Two inclined linear guide rails 34 are installed between the two positioning seats 33 arranged parallel to each other on the side of the side plate 32. The slider seat 35 is engaged and slides on the two inclined linear guide rails 34. When the linear guide cylinder 36 is activated, its output end pushes or pulls the vision sorting camera 4 to slide back and forth along the inclined linear guide rails 34. Since the inclined linear guide rails 34 are inclined, the slider seat 35 drives the vision sorting camera 4 to continuously adjust the tilt angle during the movement. This tilt angle adjustment mechanism can quickly change the camera's shooting angle and optical axis direction, so that the camera lens can be directly facing the barcode, label or feature area on the surface of the object, effectively avoiding light reflection, image distortion or information occlusion caused by a fixed angle, and ensuring the comprehensiveness and reliability of scanning and recognition. Step 3: After height adjustment, for sorting objects of different shapes and orientations, activate the linear guide cylinder 36 located on one side of one of the support seats 31 in the tilt adjustment mechanism 3. The output end of the linear guide cylinder 36 passes through one of the positioning seats 33 and extends to connect with the side of the vision sorting camera 4. The side plate 32, which is assembled between the two support seats 31, is inclined. Two inclined linear guide rails 34 are installed between the two positioning seats 33 arranged parallel to each other on the side of the side plate 32. The slider seat 35 is fitted and slides on the two inclined linear guide rails 34. When the linear guide cylinder 36 is activated, its output end pushes or pulls the vision sorting camera 4 to slide back and forth along the inclined linear guide rails 34. Since the inclined linear guide rails 34 are inclined, the slider seat 35 drives the vision sorting camera 4 to continuously adjust the tilt angle during the movement. This tilt angle adjustment mechanism can quickly change the camera's shooting angle and optical axis direction, allowing the camera lens to be directly facing the barcode, label, or feature area on the object's surface. This effectively avoids problems such as light reflection, image distortion, or information obstruction caused by a fixed angle, ensuring the comprehensiveness and reliability of scanning and recognition.
