Abstract
Description
Technical Field
[0001] This utility model relates to the field of radio frequency identification technology, and in particular to an RFID radio frequency sorting machine. Background Technology
[0002] Radio frequency (RFID) sorting is a method of classifying and sorting items using RFID technology. By embedding or attaching RFID tags to items and placing RFID readers on the conveyor line, automatic identification and tracking of items can be achieved. When an item passes by an RFID reader, the reader reads the RFID tag information and sends it to the control system. Based on the received information, the control system guides the sorting equipment to deliver the items to their respective destinations, thus completing the classification and sorting process.
[0003] Radio frequency (RFID) sorting technology is widely used in warehousing and logistics, improving the efficiency, accuracy, and automation of item classification and sorting. Through RFID, real-time tracking and management of items can be achieved, avoiding errors and delays that may occur during manual operations, accelerating the logistics process, and improving overall operational efficiency. RFID sorting technology can also be combined with other sensors and control systems to achieve intelligent logistics management, reducing costs, increasing efficiency, and providing convenient and fast services for enterprises.
[0004] In summary, RFID technology enables the automatic identification, tracking, and sorting of goods, providing a more efficient, accurate, and intelligent solution for warehouse logistics management. The application of RFID technology can optimize logistics operations, improve management efficiency, and provide higher-quality logistics services.
[0005] However, in existing technologies, when combining radio frequency identification with conveyor belts, a robotic arm is usually required to pick up the items. For most companies, equipping a robotic arm to pick up items from two parallel conveyor belts is a very high cost. Therefore, there is a need for an RFID sorting machine that can adapt to two conveyor lines and perform sorting without the need for a robotic arm.
[0006] Existing technologies often involve lateral pushing mechanisms, such as cylinders or hydraulic cylinders, to push the conveyed items and adjust their position. However, when pushing items, cylinders or similar mechanisms may not be able to adjust their output force, which may directly act on the items, or the items may be damaged, or the items may fall off the conveyor belt due to excessive force.
[0007] Therefore, an RFID radio frequency sorting machine is proposed to solve or alleviate the above problems. Utility Model Content
[0008] The purpose of this invention is to address the shortcomings of existing technologies by proposing an RFID radio frequency sorting machine.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] An RFID radio frequency sorting machine includes a worktable, an infeed conveying mechanism disposed on the worktable, a dual-path conveying mechanism disposed on the same path as the infeed conveying mechanism, and a path adjustment mechanism, wherein the path adjustment mechanism adjusts the width of the dual-path conveying mechanism to form a straight path and a Z-shaped path.
[0011] Preferably, the dual-path conveying mechanism includes several drive rollers rotatably arranged on the same path, side baffles and intermediate baffles located on both sides of some of the drive rollers, several splined shafts, and several cylindrical shafts. One end of several of the drive rollers located between the side baffles and the intermediate baffles is coaxially connected to the cylindrical shafts and passes through the intermediate baffles. One end of the remaining drive rollers is provided with a sliding groove, and the splined shaft is slidably connected in the sliding groove. The outer ring of the splined shaft is fitted with a spring that abuts against the end face of the drive roller.
[0012] Preferably, the dual-path conveying mechanism further includes a support plate fixedly connected to the top surface of the workbench, several bearing seats located on one side of the support plate, a rotating shaft fixedly connected to the inner ring of the bearing seat, and a driving component for driving the rotating shaft to rotate. The rotating shaft passes through the support plate and is coaxially connected to a cylindrical shaft or a spline shaft. The other end of the spring abuts against the end face of the support plate.
[0013] Preferably, the driving component includes a transmission gear fixedly connected to the rotating shaft, a transmission chain that transmits power to several transmission gears, and a drive motor. The drive motor is fixedly connected to the worktable, and its output shaft is coaxially connected to one of the rotating shafts.
[0014] Preferably, the end of the drive roller away from the support plate has a spherical surface.
[0015] Preferably, the path adjustment mechanism includes a cylinder fixedly connected to the top surface of the workbench, an inclined plate fixedly connected to the movable end of the cylinder, and a guide plate one and a guide plate two fixedly connected to both ends of the inclined plate, wherein the guide plate one and the guide plate two are both arranged parallel to the support plate.
[0016] Preferably, the path adjustment mechanism further includes sliding sleeves located on both sides of the cylinder and sliding rods slidably connected within the sliding sleeves, with the two sliding rods respectively fixedly connected to guide plate one and guide plate two.
[0017] Preferably, it also includes a bracket fixedly connected to the workbench and an RF reader fixedly connected to the bracket, the RF reader being located between the drive rollers between the middle baffle and the side baffle.
[0018] Preferably, it also includes a collection box one and a collection box two, which are located below the discharge ends of the straight path and the Z-shaped path, respectively.
[0019] This utility model has the following beneficial effects:
[0020] This invention uses a cylinder to control the displacement of an inclined plate, guide plate one, and guide plate two, thereby driving the drive roller to achieve Z-shaped path conversion. The inclined plate, guide plate, and drive roller make point contact to reduce friction and ensure smooth rotation. The path switching is completed by a microcontroller connected to an RF reader to control the cylinder, avoiding damage to the items and changes in the path. The items are moved by friction rather than by direct force. The spring releases elastic potential energy to restore the straight path, enabling the items to fall into different collection boxes.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] An RFID radio frequency sorting machine, such as Figure 1 As shown, the device includes a workbench 1, a feeding conveyor mechanism mounted on the workbench 1, a dual-path conveyor mechanism mounted on the same path as the feeding conveyor mechanism, a path adjustment mechanism, a first collection box 22 and a second collection box 23, a bracket 2 fixedly connected to the workbench 1, and an RFID reader 3 fixedly connected to the bracket 2. The path adjustment mechanism adjusts the width of the dual-path conveyor mechanism to form a straight path and a Z-shaped path. The first collection box 22 and the second collection box 23 are located below the discharge ends of the straight path and the Z-shaped path, respectively.
[0026] like Figure 2As shown, the dual-path conveying mechanism includes several drive rollers 13 rotatably arranged on the same path, side baffles 12 and intermediate baffles 11 located on both sides of some of the drive rollers 13, several splined shafts 14, several cylindrical shafts 10, a support plate 4 fixedly connected to the top surface of the worktable 1, several bearing seats 6 located on one side of the support plate 4, rotating shafts 5 fixedly connected to the inner ring of the bearing seats 6, and a drive component for driving the rotating shafts 5 to rotate. The end of the drive roller 13 away from the support plate 4 has a spherical surface. One end of the drive rollers 13 located between the side baffles 12 and the intermediate baffle 11 is coaxially connected to the cylindrical shafts 10 and passes through the middle baffle. A baffle 11 is provided, and a groove is provided at one end of the remaining drive rollers 13. A spline shaft 14 is slidably connected in the groove. A spring 15 is sleeved on the outer ring of the spline shaft 14 and abuts against the end face of the drive roller 13. A rotating shaft 5 is provided through the support plate 4. The rotating shaft 5 is coaxially connected to the cylindrical shaft 10 or the spline shaft 14. The other end of the spring 15 abuts against the end face of the support plate 4. The driving components include a transmission gear 7 fixedly connected to the rotating shaft 5, a transmission chain 8 that transmits several transmission gears 7, and a drive motor 9. The drive motor 9 is fixedly connected to the worktable 1, and its output shaft is coaxially connected to one of the rotating shafts 5.
[0027] The radio frequency reader 3 is located between the drive rollers 13, which are between the middle baffle 11 and the side baffle 12.
[0028] The path adjustment mechanism includes a cylinder 16 fixedly connected to the top surface of the workbench 1, an inclined plate 19 fixedly connected to the movable end of the cylinder 16, a guide plate 20 and a guide plate 21 fixedly connected to both ends of the inclined plate 19, a sliding sleeve 17 located on both sides of the cylinder 16, and a sliding rod 18 slidably connected in the sliding sleeve 17. The guide plate 20 and the guide plate 21 are both arranged parallel to the support plate 4, and the two sliding rods 18 are fixedly connected to the guide plate 20 and the guide plate 21 respectively.
[0029] This invention uses cylinder 16 in the path adjustment mechanism to move inclined plate 19, guide plate 10, and guide plate 21. During this process, slide rod 18 slides along with it under the guidance of sliding sleeve 17, allowing inclined plate 19, guide plate 10, and guide plate 21 to move stably. During displacement, inclined plate 19, guide plate 10, and guide plate 21 contact the spherical surface of drive roller 13. This ensures that one end of drive roller 13 makes point contact with inclined plate 19, guide plate 10, and guide plate 21, minimizing frictional resistance to the rotation of drive roller 13. Thus, even when in contact with drive roller 13, it still rotates smoothly. Under the push of inclined plate 19, guide plate 10, and guide plate 21, the originally straight path becomes a Z-shaped path, and the drive roller 13 between the middle baffle 11 and the side baffle 12 will not... The drive roller 13, outside the middle baffle 11 and side baffle 12, slides with the spline shaft 14 through the groove. During this process, the spline shaft 14 still drives the drive roller 13, causing it to rotate. However, the available length of the drive roller 13 and spline shaft 14 will be shortened, and the spring 15 will be compressed until a Z-shaped path is formed, causing the item to fall into the second collection box 23. As soon as the cylinder 16 returns to its original state, the spring 15 will release its elastic potential energy, pushing the drive roller 13 back to its original position, changing back to a straight path, causing the item to fall into the first collection box 22. This method is to change the drive path so that the item is moved by friction, rather than directly applying the huge force of the cylinder 16 to the item, to avoid the item being damaged or falling directly. The switching between the two paths is read by the RF reader 3. The path switching is completed by connecting the RF reader 3 and the cylinder 16 to the microcontroller controller.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
