Description

Technical Field

[0001] This application relates to the field of logistics and warehousing automation technology, and in particular to an intelligent sorting device for logistics and warehousing. Background Technology

[0002] The logistics industry is currently facing an explosive growth in parcel sorting demand. Traditional manual sorting methods are inefficient and have a high error rate. Automated sorting technology is gradually becoming more widespread. In 2022, the global market size of intelligent sorting equipment reached US$8.7 billion, with a compound annual growth rate of over 15%.

[0003] The mainstream solutions for existing automated sorting technologies include cross-belt sorters, slider sorters, and AGV robot sorting systems. These systems collect package information through technologies such as barcode recognition, weight detection, and volume scanning. However, due to their complex mechanical structures, the failure rate remains high, and the mechanical adaptability of existing equipment is poor when sorting irregular package items.

[0004] Therefore, this application provides an intelligent sorting device for logistics warehousing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an intelligent sorting device for logistics warehousing, which overcomes the deficiencies of existing technologies and aims to solve the problems of existing mainstream automated sorting technologies, including cross-belt sorters, slider sorters, and AGV robot sorting systems. These systems collect package information through technologies such as barcode recognition, weight detection, and volume scanning. However, due to their complex mechanical structures, they suffer from high failure rates, and their mechanical adaptability is poor when sorting irregularly shaped packages.

[0006] To achieve the above objectives, this application provides the following technical solution: an intelligent sorting device for logistics warehousing, comprising two sets of side supports, each set of side supports having two sets of adjustable support legs fixedly installed at its bottom end; two sets of drive rollers rotatably connected between the two sets of side supports; a conveyor belt drivingly connected to the outer surface of the two sets of drive rollers; a vertical frame fixedly installed at the top of each set of side supports; a horizontal plate fixedly installed at the top of each set of vertical frames; a 3D vision camera and a laser rangefinder fixedly installed at the bottom end of the horizontal plate; the laser rangefinder being located at the 3D vision camera. On one side, several sets of uprights are fixedly installed on one side of the set of side supports. An independent controller is fixedly installed at the top of each upright. An electric push rod is fixedly installed on one side of each upright. A push plate is fixedly installed at the telescopic end of the electric push rod. A guide plate is fixedly installed in the middle of the set of side supports. A master controller is fixedly installed on one side of the set of side supports. The master controller is located on one side of the guide plate and is electrically connected to the 3D vision camera, the laser rangefinder, and the several sets of independent controllers. Several sorting chutes are provided on the top of the guide plate.

[0007] By adopting the above technical solution, after the package enters the conveyor belt, the 3D vision camera collects the three-dimensional contour data of the package, and the laser rangefinder obtains the precise position coordinates. After the data is fed back to the central controller, the central controller calculates the optimal sorting path and controls the corresponding independent controller to drive the electric push rod to extend. The push plate pushes the package into the designated sorting chute. This device has a simple structure and achieves precise positioning of irregularly shaped packages through the three-dimensional contour recognition technology of the 3D vision camera. The electric push rod completes rapid sorting, which greatly improves the success rate of sorting irregularly shaped packages and enhances sorting efficiency.

[0008] As a preferred technical solution of this application, an airflow generating mechanism is provided at the telescopic end of a set of electric push rods. The airflow generating mechanism includes a push box, which is fixedly installed at the telescopic end of the corresponding electric push rod. A bracket is fixedly installed inside the push box, and a fan is fixedly installed in the middle of the bracket. The fan is electrically connected to the main controller.

[0009] By adopting the above technical solution, when the 3D vision camera detects lightweight packages such as envelopes, the central controller starts the fan. The fan reverses to generate negative pressure, causing the package to be adsorbed onto one side of the push box, preventing the package from drifting. Then, the upright connected to the fan pushes the push box to the sorting chute to stop the operation. This helps lightweight packages to smoothly leave the conveyor belt and enter the corresponding sorting chute, improving the success rate of sorting lightweight packages.

[0010] As a preferred technical solution of this application, a motor frame is fixedly installed on one side of a set of side support frames, a geared motor is fixedly installed on the top of the motor frame, and the output end of the geared motor is fixedly installed with a set of drive rollers.

[0011] By adopting the above technical solution, a set of drive rollers is driven to rotate by a geared motor, and another set of drive rollers is driven to rotate by a conveyor belt, so as to achieve the purpose of continuously transporting packages by the conveyor belt.

[0012] As a preferred technical solution of this application, two sets of dustproof mesh plates are fixedly installed inside the push box, and the two sets of dustproof mesh plates are respectively located at the air outlet and air inlet of the fan.

[0013] By adopting the above technical solution, two sets of dustproof mesh panels reduce the amount of dust entering the push box, thus improving the protection effect on the fan.

[0014] As a preferred technical solution of this application, the conveyor belt is a polyurethane conveyor belt, and a high-friction coefficient rubber layer is fixedly installed on the outer surface of the conveyor belt.

[0015] By adopting the above technical solution, the conveyor belt specifically uses German Mireite 8mm thick polyurethane belt, which has good tensile strength. Through the high friction coefficient rubber layer on the surface, the friction between the belt and the package is increased, reducing the chance of the package slipping.

[0016] As a preferred technical solution of this application, a pressure sensor is fixedly installed on the side of the push plate away from the electric push rod, and a soft pad is fixedly installed on the side of the push plate away from the electric push rod, the soft pad covering the outer periphery of the pressure sensor.

[0017] By adopting the above technical solution, when the pusher contacts the package, the pressure sensor detects the pressure when pushing the package, which indicates that the sorting is successful, thus improving the practicality of use.

[0018] As a preferred technical solution of this application, the adjustable support mechanism includes a pad foot located below the side support frame. A screw is rotatably connected to the top of the pad foot, and a sleeve is threadedly connected to the top of the screw. The sleeve is rotatably connected to the bottom of the side support frame, and an adjustment ring is fixedly installed on the outer surface of the screw.

[0019] By adopting the above technical solution, the screw is rotated by rotating the adjusting ring, and the sleeve is raised and lowered by the thread on the outer surface of the screw, which is beneficial for adjusting the height of the two sets of side supports.

[0020] As a preferred technical solution of this application, a camera is fixedly installed on one side of the horizontal plate, and the camera is electrically connected to the main controller.

[0021] By adopting the above technical solution, real-time video of the sorting area above the conveyor belt is captured by a camera, which facilitates subsequent review of package issues.

[0022] The beneficial effects of this application are:

[0023] 1. After the package enters the conveyor belt, a 3D vision camera collects the package's three-dimensional contour data, and a laser rangefinder obtains the precise position coordinates. After the data is fed back to the central controller, the central controller calculates the optimal sorting path and controls the corresponding independent controller to drive the electric push rod to extend. The push plate pushes the package into the designated sorting chute. This device has a simple structure and achieves precise positioning of irregularly shaped packages through the three-dimensional contour recognition technology of the 3D vision camera. The electric push rod completes rapid sorting, which greatly improves the success rate of sorting irregularly shaped packages and enhances sorting efficiency.

[0024] 2. When the 3D vision camera detects lightweight packages such as envelopes, the central controller starts the fan. The fan reverses to generate negative pressure, causing the package to adhere to one side of the push box, preventing the package from drifting. Then, the upright connected to the fan pushes the push box to the sorting chute to stop the operation. This helps lightweight packages to smoothly leave the conveyor belt and enter the corresponding sorting chute, improving the success rate of sorting lightweight packages. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Reference Figure 1-4 A smart sorting device for logistics warehousing includes two sets of side supports 1. Two sets of adjustable support legs 2 are fixedly installed at the bottom of each set of side supports 1. Two sets of drive rollers 3 are rotatably connected between the two sets of side supports 1. A conveyor belt 4 is driven to the outer surface of the two sets of drive rollers 3. A vertical frame 5 is fixedly installed at the top of each set of side supports 1. A horizontal plate 6 is fixedly installed at the top of each set of vertical frames 5. A 3D vision camera 7 and a laser rangefinder 8 are fixedly installed at the bottom of the horizontal plate 6. The laser rangefinder 8 is located to one side of the 3D vision camera 7. Several sets of uprights 9 are fixedly installed on one side of each set of side supports 1. An independent controller 10 is fixedly installed at the top of each upright. An electric push rod 11 is fixedly installed on one side of the 9. A push plate 12 is fixedly installed on the telescopic end of the electric push rod 11. A guide plate 13 is fixedly installed in the middle of a set of side support frames 1. A master controller 14 is fixedly installed on one side of the set of side support frames 1. The master controller 14 is located on one side of the guide plate 13 and is electrically connected to the 3D vision camera 7, the laser rangefinder 8, and several sets of independent controllers 10. Several sorting chutes 17 are provided on the top of the guide plate 13. A motor frame 21 is fixedly installed on one side of the set of side support frames 1. A geared motor 22 is fixedly installed on the top of the motor frame 21. The output end of the geared motor 22 is fixedly installed with a set of drive rollers 3.

[0032] After the package enters the conveyor belt 4, the 3D vision camera 7 collects the package's three-dimensional contour data, and the laser rangefinder 8 obtains the precise position coordinates. After the data is fed back to the central controller 14, the central controller 14 calculates the optimal sorting path and controls the corresponding independent controller 10 to drive the electric push rod 11 to extend. The push plate 12 pushes the package into the designated sorting chute 17. This device has a simple structure. It achieves precise positioning of irregularly shaped packages through the three-dimensional contour recognition technology of the 3D vision camera 7 and completes rapid sorting using the electric push rod 11, which greatly improves the success rate of sorting irregularly shaped packages and increases sorting efficiency. The geared motor 22 drives a set of drive rollers 3 to rotate, which in turn drives another set of drive rollers 3 to rotate through the conveyor belt 4, so that the conveyor belt 4 continuously transports the packages.

[0033] Reference Figure 2-4An airflow generating mechanism 15 is provided at the telescopic end of a set of electric push rods 11. The airflow generating mechanism 15 includes a push box 1501, which is fixedly installed at the telescopic end of the corresponding electric push rod 11. A bracket 1502 is fixedly installed inside the push box 1501, and a fan 1503 is fixedly installed in the middle of the bracket 1502. The fan 1503 is electrically connected to the main controller 14. Two sets of dustproof mesh plates 16 are fixedly installed inside the push box 1501. The two sets of dustproof mesh plates 16 are located at the air outlet and air inlet of the fan 1503, respectively.

[0034] When the 3D vision camera 7 detects lightweight packages such as envelopes, the main controller 14 starts the fan 1503. The fan 1503 reverses to generate negative pressure, causing the package to adhere to one side of the push box 1501, preventing the package from drifting. Then, the upright 9 connected to the fan 1503 pushes the push box 1501 to the sorting chute to stop the operation. This facilitates the smooth removal of lightweight packages from the conveyor belt 4 and into the corresponding sorting chute 17, improving the success rate of lightweight package sorting. The two sets of dustproof mesh panels 16 reduce dust from entering the push box 1501, improving the protection of the fan 1503.

[0035] Reference Figure 1-3 The conveyor belt 4 is a polyurethane conveyor belt, and a high-friction coefficient rubber layer is fixedly installed on the outer surface of the conveyor belt 4. The adjustable support mechanism 2 includes a pad 201, which is located below the side support frame 1. A screw 202 is rotatably connected to the top of the pad 201, and a sleeve 203 is threadedly connected to the top of the screw 202. The sleeve 203 is rotatably connected to the bottom of the side support frame 1, and an adjusting ring 204 is fixedly installed on the outer surface of the screw 202. The conveyor belt 4 is specifically made of German MIRI 8mm thick polyurethane belt, which has good tensile strength. Through the high-friction coefficient rubber layer on the surface, the friction between the belt and the package is increased, reducing the probability of the package slipping. By rotating the adjusting ring 204, the screw 202 is driven to rotate, and the sleeve 203 is raised and lowered under the action of the thread on the outer surface of the screw 202, which is conducive to the height adjustment of the two sets of side support frames 1.

[0036] Reference Figure 1-3 A pressure sensor 18 is fixedly installed on the side of the push plate 12 away from the electric push rod 11, and a soft pad 19 is fixedly installed on the side of the push plate 12 away from the electric push rod 11, covering the outer periphery of the pressure sensor 18; a camera 20 is fixedly installed on one side of the horizontal plate 6, and the camera 20 is electrically connected to the central controller 14; when the push plate 12 contacts the package, the pressure sensor 18 senses the pressure when pushing the package, which indicates that the sorting is successful, improving the practicality of use; the camera 20 collects video of the sorting area above the conveyor belt 4 in real time, which is convenient for subsequent review of package problems.

[0037] Working principle: After the package enters the conveyor belt 4, the 3D vision camera 7 collects the package's three-dimensional contour data, and the laser rangefinder 8 obtains the precise position coordinates. After the data is fed back to the central controller 14, the central controller 14 calculates the optimal sorting path and controls the corresponding independent controller 10 to drive the electric push rod 11 to extend. The push plate 12 pushes the package into the designated sorting chute 17. This device has a simple structure. It achieves precise positioning of irregularly shaped packages through the three-dimensional contour recognition technology of the 3D vision camera 7 and completes rapid sorting using the electric push rod 11. The sorting process greatly improves the success rate of sorting irregularly shaped packages and increases sorting efficiency. When the 3D vision camera 7 detects lightweight packages such as envelopes, the main controller 14 starts the fan 1503. The fan 1503 reverses to generate negative pressure, causing the package to be adsorbed to one side of the push box 1501 to prevent the package from drifting. Then, the upright 9 connected to the fan 1503 pushes the push box 1501 to the sorting chute to stop the operation. This helps the lightweight package to smoothly leave the conveyor belt 4 and enter the corresponding sorting chute 17, thus improving the success rate of sorting lightweight packages.

[0038] Among them, a set of drive rollers 3 are driven to rotate by a geared motor 22, and another set of drive rollers 3 are driven to rotate by a conveyor belt 4, so that the conveyor belt 4 continuously transports the package. Two sets of dustproof mesh plates 16 reduce dust from entering the push box 1501 and improve the protection effect of the fan 1503.

[0039] Meanwhile, the conveyor belt 4 is made of German Mirren 8mm thick polyurethane belt, which has good tensile strength. The high friction coefficient rubber layer on the surface increases the friction between the belt and the package, reducing the chance of the package slipping. When the push plate 12 comes into contact with the package, the pressure sensor 18 senses the pressure when pushing the package, which means that the sorting is successful, thus improving the practicality of use.

[0040] In addition, the screw 202 is rotated by rotating the adjusting ring 204, and the sleeve 203 is raised and lowered by the thread on the outer surface of the screw 202, which is conducive to the height adjustment of the two sets of side support frames 1; the video of the sorting area above the conveyor belt 4 is collected in real time by the camera 20, which is convenient for subsequent review of package problems.

[0041] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
