Description

Technical Field

[0001] This invention relates to the field of logistics transportation, specifically a logistics conveyor belt based on RFID technology. Background Technology

[0002] With the rapid development of the modern logistics industry, automated warehousing and sorting systems have become a key link in improving logistics efficiency. Radio frequency identification (RFID) technology, due to its advantages such as non-contact identification, batch reading, and large data capacity, is widely used in logistics conveying systems to achieve real-time tracking and management of cargo flow information. Electronic tags are attached to the surface of goods. When goods move along the conveyor belt and pass through the RFID reader, the antenna inside the RFID sends radio frequency signals to the electronic tag and receives the response signal returned by the tag, thereby completing the automatic identification and collection of cargo identity information.

[0003] However, in practical applications, the accuracy of RFID readers in identifying electronic tags is constrained by a variety of factors, among which signal interference between tags is particularly prominent. When the distance between two adjacent goods on the conveyor belt is too small, the electronic tags attached to them are too close in physical position. This causes the two tags to be within the reader's recognition range and respond simultaneously when the RFID reader's antenna sends a signal. At this time, the radio frequency signals returned by the two tags are superimposed and mixed in space, resulting in signal collision. This makes it impossible for the RFID reader to correctly parse the complete information of a single tag, leading to identification errors such as missed readings, misreadings, or reading failures. This signal interference problem is more serious in scenarios where goods are densely arranged, the conveyor belt runs at a high speed, or the reader's recognition range is large.

[0004] In particular, the aforementioned signal interference problem is further aggravated for goods that are easily moved or rolled, such as rod-shaped paper tubes. When these goods are transported on a conveyor belt, their cylindrical structure is inherently unstable, making them prone to rolling, displacement, or coming together. When two adjacent paper tubes roll and stick together, the distance between their attached electronic tags decreases drastically, potentially leading to physical contact or overlap. In this situation, the coupling effect of the radio frequency signals between the two tags is significantly enhanced, and the level of signal interference far exceeds that of normal conditions. RFID readers can hardly distinguish the independent signals of the two tags, resulting in serious identification errors and severely impacting the accuracy and efficiency of logistics sorting.

[0005] Therefore, a logistics conveyor belt based on RFID technology is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is: the logistics conveyor belt based on RFID technology of the present invention includes two symmetrically arranged chain conveyor belts. Multiple support rods for lifting materials are arranged on the inner side of both conveyor belts. The side wall of the support rod is connected to the pin of the conveyor belt. The end of the support rod is in the shape of the letter "C". Two opposite support rods on the two conveyor belts lift the materials together. A support frame is provided between the two conveyor belts, and multiple RFID readers are provided on the support frame. The RFID readers are used to read and write passive tags on the materials.

[0008] Preferably, each of the conveyor belts has a sliding rod extending from the pin end, the sliding rod passing through the support rod, and a spring is provided between the support rod and the conveyor belt; The support frame includes two symmetrical rods with their ends close together and their middle portions far apart. The outer walls of the two rods press against the support rod, which slides along the slide bar.

[0009] Preferably, two cylinders are symmetrically arranged above the first end of the conveyor belt, with the output ends of the two cylinders facing each other, and each output end of the two cylinders is fixedly connected to a push plate. Two positioning plates are symmetrically arranged on the upper outer side of the conveyor belt, and a lead screw is threaded between the two positioning plates.

[0010] Preferably, each of the positioning plates is provided with multiple L-shaped support plates, the horizontal part of the support plate extends upward towards the support frame, and each support plate is provided with multiple scanners for scanning QR codes pasted on the material.

[0011] Preferably, each of the support plates has an adjustment hole on its horizontal portion, the adjustment hole being opened along the length direction of the horizontal portion, and multiple scanners are arranged in each adjustment hole.

[0012] Preferably, a base plate is fixedly connected to the output end of each cylinder, and multiple buffer rods are slidably connected to each base plate. One end of each buffer rod is connected to the back of the base plate by a tension spring, and the other end of each buffer rod is fixedly connected to a push plate.

[0013] Preferably, a groove is formed on each of the support rods at a position opposite to the outer wall of the rod body, and a roller is provided in the groove, which rolls against the rod body.

[0014] Preferably, the interior of each rod is hollow, and an oil outlet hole is opened on the outer wall of each rod, which connects to the interior of the rod, and an oil replenishment pipe is connected to the end of the rod.

[0015] Preferably, two conveyor belts are symmetrically arranged at the end of the conveyor belt, the beginning of the conveyor belt is connected to the end of the conveyor belt by belt drive, and each conveyor belt surface is provided with a pallet.

[0016] Preferably, the end surface of the support rod is provided with multiple rotating grooves, and each rotating groove is provided with a ball bearing.

[0017] The advantages of this invention are: 1. In this invention, two symmetrically arranged chain conveyor belts are used, and rod-shaped materials are supported by oppositely arranged support rods. The support rods separate adjacent materials and form a fixed physical distance. When the materials move with the conveyor belt, the spacing of the support rods ensures that the electronic tags of any two adjacent materials always maintain a safe distance. This avoids the tag signal collision and interference problems caused by the rolling and displacement of goods on traditional conveyor belts. Even for rod-shaped paper tube materials that are easy to roll, the "C"-shaped ends of the support rods can effectively limit the movement of the materials, prevent axial movement or circumferential rolling, reduce RFID identification errors caused by the physical proximity of tags, and greatly improve the identification accuracy.

[0018] 2. In this invention, multiple RFID readers are distributed on the support frame to form a three-dimensional identification area covering the middle section of the conveyor belt. No matter how the specific position of the material on the support rod is finely adjusted, there is always at least one reader at the optimal reading angle, which significantly improves the coverage of tag identification and the success rate of the first reading.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Reference Figure 1 - Figure 6 A logistics conveyor belt based on RFID technology includes two symmetrically arranged chain conveyor belts 1. Both chain conveyor belts 1 are driven by servo motors, which are controlled by a PLC, enabling the two conveyor belts 1 to start and stop synchronously or rotate slowly. Multiple support rods 2 for lifting materials 101 are arranged on the inner side of each conveyor belt 1. The support rods 2 move in a circular motion with the conveyor belt 1. The sidewalls of the support rods 2 are connected to pins on the conveyor belt 1, and the ends of the support rods 2 are shaped like the letter "C". Two opposing support rods 2 on the two conveyor belts 1 jointly lift the material 101. The first... The first position is the loading station, where manual workers place the rod-shaped materials 101 one by one onto the end of the support rod 2. The second position is the unloading station, where the support rod 2 moves with the conveyor belt 1, and the end of the support rod 2 automatically rotates downwards, allowing the materials 101 to be automatically unloaded. A support frame 3 is provided between the two conveyor belts 1, and multiple RFID readers 4 are provided on the support frame 3. The RFID readers 4 are used to read and write passive tags on the materials 101. In this embodiment, the focus is on passive tags, which do not require built-in batteries and rely entirely on the electromagnetic waves emitted by the RFID readers 4 to obtain energy and transmit data back. The specific operation of the logistics conveyor belt is as follows: material 101 is placed on support rod 2, and conveyor belt 1 drives material 101 to move slowly through support rod 2. Material 101 moves to the top of support frame 3. RFID reader 4 on support frame 3 continuously emits ultra-high frequency electromagnetic waves. After receiving the waves, the passive tag antenna converts them into DC power through a rectifier circuit to activate the chip. After the tag is activated, it transmits data back through backscattering technology. Then, the reader receives the weak back signal, filters, amplifies, demodulates it, extracts the digital information, completes the identification, and records it into the logistics system for storage. Multiple RFID readers 4 are installed on the support frame 3, and these readers are distributed between the two conveyor belts 1, enabling more comprehensive reading of the passive tags on the material 101 and improving the reading success rate. In the event that multiple RFID readers 4 read the same material 101 tag data, the system employs a data verification and deduplication mechanism. Subsequent data is first compared with the previously read data. If the comparison results are consistent, it is determined to be a duplicate reading of the same tag, and subsequent data automatically overwrites the previous data, ensuring that only one unique identification record is retained for the material 101 in the logistics system. If the data is inconsistent after comparison, it is determined to be tag information for different materials 101, and the system will store the data uploaded by each reader separately. In this invention, two symmetrically arranged chain conveyor belts 1 are used, and the rod-shaped materials 101 are supported by oppositely arranged support rods 2. The support rods 2 separate adjacent materials 101 and form a fixed physical distance. When the materials 101 move with the conveyor belt 1, the spacing of the support rods 2 ensures that the electronic tags of any two adjacent materials 101 always maintain a safe distance. This avoids the tag signal collision and interference problems caused by the rolling and displacement of goods on the traditional conveyor belt 1. Even for the easily rolling rod-shaped paper tube materials 101, the "C"-shaped end of the support rod 2 can effectively limit the movement of the materials 101 axially or circumferentially, reduce RFID identification errors caused by the physical proximity of the tags, and greatly improve the identification accuracy. Multiple RFID readers 4 are scattered on the support frame 3 to form a three-dimensional identification area covering the middle section of the conveyor belt 1. No matter how the specific position of the material 101 on the support rod 2 is finely adjusted, there will always be at least one reader at the optimal reading angle, which significantly improves the coverage of tag identification and the success rate of the first reading.

[0023] Reference Figure 1 - Figure 3 Each of the conveyor belts 1 has a sliding rod 5 extending from the pin end, the sliding rod 5 passing through the support rod 2, and a spring 6 is provided between the support rod 2 and the conveyor belt 1; the support frame 3 includes two symmetrical rods 7, the ends of the two rods 7 are close to each other, the middle parts are far apart from each other, and the outer walls of the two rods 7 press against the support rod 2, and the support rod 2 slides along the sliding rod 5. When the support rod 2 moves with the conveyor belt 1 to the area of ​​the support frame 3, the outer walls of the two symmetrical rods 7 of the support frame 3 press against the support rod 2, forcing the support rod 2 to slide along the slide bar 5 and compress the spring 6. At this time, the support rod 2 and the material 101 being supported undergo a controllable relative displacement. The dynamic avoidance causes the end of the support rod 2, which may have covered or blocked the passive tag, to shift, completely exposing the tag to the electromagnetic wave field of the RFID reader 4. This reduces the shielding effect of the physical support rod 2 on the radio frequency signal and the possibility of physical obstruction, which helps to increase the probability of the passive tag being successfully activated and read.

[0024] Reference Figure 4 - Figure 6 Two cylinders 8 are symmetrically arranged above the first end of the conveyor belt 1. The output ends of the two cylinders 8 are arranged opposite each other, and push plates 9 are fixedly connected to the output ends of the two cylinders 8 respectively. Two positioning plates 10 are symmetrically arranged on the upper outer side of the conveyor belt 1, and a lead screw 11 is threaded between the two positioning plates 10. The lead screw 11 is mounted above the conveyor belt 1 via a frame. A motor, controlled by a PLC, drives the lead screw 11 to rotate in either direction, thus controlling the lead screw 11 to move the positioning plates 10 towards each other. The cylinder 8, also controlled by a PLC, moves the two push plates 9 towards each other, symmetrically pressing and confining the material 101 onto the two support rods 2. The stroke of the cylinder 8 is recorded, and the length of the material 101 is determined by the PLC and the backend control system. The motor then drives the two positioning plates 10 to adjust their spacing. The spacing between the two positioning plates 10 is slightly larger than the length of the material 101. When the material 101 moves between the two positioning plates 10, the rod 7 presses against the support rod 2, and the support rod 2 moves relative to the material 101. At the same time, the material 101 is still within the readable range of the RFID reader 4 under the restriction of the positioning plates 10. This design is more suitable for identifying the same batch of materials 101, which have the same length. After placing the first material 101 of the same batch, there is no need to use the cylinder 8 to measure the length of the material 101.

[0025] Reference Figure 1 - Figure 7 ,as well as Figure 10 Each of the positioning plates 10 is provided with a plurality of L-shaped support plates 12, the horizontal part of the support plate 12 extends upward toward the support frame 3, and each support plate 12 is provided with a plurality of scanners 13, which are used to scan the QR codes pasted on the material 101. The scanner 13 is not only mounted on the support plate 12, but also on the support frame 3. Multiple scanners 13 on both the support plate 12 and the support frame 3 jointly scan the QR code attached to the surface of the material 101. Typically, passive labels also have QR codes or barcodes on their surfaces, providing a dual-layer identification channel for the material 101. The material 101 is located between the support plate 12 and the support frame 3, and the multiple scanners 13 can then scan and identify three areas, such as... Figure 10 As shown, it can fully recognize the QR code or barcode on the surface of material 101; The above design enables the system to simultaneously possess two independent technical channels: RFID radio frequency identification and QR code / barcode optical recognition. When passive tags fail to identify RFID due to signal interference, insufficient power, or physical obstruction, scanner 13 can obtain the same material 101 information by recognizing the QR code or barcode on the tag surface. Conversely, when optical recognition is affected by dirt, reflection, or poor angle, the RFID channel can serve as a backup. This dual redundancy design significantly improves the system's identification success rate and data acquisition reliability under complex operating conditions, meeting the logistics system's stringent requirement of zero missed readings. The stringent requirements and the three-dimensional spatial layout of multiple scanners 13 form regional coverage, enabling omnidirectional, blind-spot-free recognition of QR codes on the surface of material 101. The surface of material 101 is scanned simultaneously from three different perspectives, forming a stereoscopic visual coverage. Regardless of whether the QR code or barcode is attached to the top, side, or bottom surface of material 101, one or more scanners 13 are always at the optimal reading angle, completely eliminating the blind spot problem of single-view scanning. This achieves omnidirectional, blind-spot-free recognition of the cylindrical surface of rod-shaped material 101, significantly improving the first-time success rate and complete coverage of optical recognition.

[0026] Reference Figure 4 - Figure 6 Each of the support plates 12 has an adjustment hole 14 on its horizontal portion. The adjustment hole 14 is opened along the length of the horizontal portion, and multiple scanners 13 are provided in each adjustment hole 14. The end shell of the scanner 13 is provided with an adjusting bolt 15, which passes through the adjusting hole 14. The scanner 13 is fastened to the support plate 12 by means of a nut engaging the adjusting bolt 15. By loosening the nut and sliding the scanner 13, the position of the scanner 13 can be adjusted to adapt to the scanning and processing of materials 101 of different lengths, thereby improving flexibility. This design is also more suitable for scanning and processing materials 101 of the same batch and specifications.

[0027] Reference Figure 6 and Figure 9 Each cylinder 8 has a base plate 16 fixedly connected to its output end. Multiple buffer rods 17 are slidably connected to each base plate 16. One end of each buffer rod 17 is connected to the back of the base plate 16 by a tension spring 18. The other end of each buffer rod 17 is fixedly connected to a push plate 9. When the cylinder 8 drives the push plate 9 to contact the end of the material 101, if the contact speed is too fast or the position of the material 101 is deviated, the reverse impact force on the push plate 9 is first transmitted to the buffer rod 17. The buffer rod 17 slides along the base plate 16 and stretches the tension spring 18. The elastic deformation of the tension spring 18 effectively absorbs and buffers the impact kinetic energy, transforming the rigid collision into a flexible contact, reducing the possibility of crushing, deformation, or surface damage to the end of the material 101 caused by the direct hard extrusion of the push plate 9. This is particularly suitable for hollow, thin-walled rod-shaped materials 101 such as paper tubes and film rolls, improving the integrity rate of material 101 processing. At the same time, a touch switch can be set between the base plate 16 and the push plate 9. The touch switch is specifically fixed on the base plate 16, with the contact of the touch switch facing the back of the push plate 9. When the push plate 9 is subjected to the reverse thrust of the material 101, the push plate 9 moves closer to the base plate 16, and the back of the push plate 9 presses against the contact of the touch switch. The switch is triggered and immediately sends a signal to the PLC. The PLC controls the cylinder 8 to stop output, achieving precise protection of stopping upon contact.

[0028] Reference Figure 2 , Figure 3 and Figure 8 Each of the support rods 2 has a groove at a position opposite to the outer wall of the rod body 7, and a roller 19 is provided in the groove. The roller 19 is attached to the rod body 7 and rolls. The sliding friction between the rod 7 and the support rod 2 is converted into rolling friction between the rod 7 and the roller 19, which improves the relative smoothness of movement between the rod 7 and the support plate 24, thereby improving the relative smoothness of movement between the support rod 2 and the slide rod 5, reducing the sliding jamming phenomenon between the support rod 2 and the slide rod 5, and preventing shaking, trembling or sudden jumping. This allows the supported material 101 to move above the RFID reader 4 in a stable state, avoiding sudden changes in tag posture and signal strength fluctuations caused by the shaking of the support rod 2, and improving the stability and data quality of RFID reading.

[0029] Reference Figure 2 , Figure 3 , Figure 7 and Figure 8 Each rod 7 is hollow inside, and an oil outlet hole 20 is opened on the outer wall of each rod 7. The oil outlet hole 20 connects to the inside of the rod 7, and the end of the rod 7 is connected to an oil supply pipe 21. The oil replenishment pipe 21 is connected to an external oil pump, which is controlled by a PLC to realize automatic replenishment of lubricating oil. The lubricating oil is injected into the oil replenishment pipe 21, then flows into the hollow rod body 7, and finally discharged from multiple oil outlet holes 20. The lubricating oil is spread between the roller 19 and the rod body 7, forming a stable fluid lubrication or boundary lubrication film at the contact interface, reducing friction, extending the service life of the roller 19 and the rod body 7, and reducing the frequency of maintenance and replacement.

[0030] Reference Figure 1 - Figure 5Two conveyor belts 22 are symmetrically provided at the end of the conveyor belt 1. The beginning of the conveyor belt 22 is connected to the end of the conveyor belt 1 by a belt 23, and each conveyor belt 22 is provided with a support plate 24 on its surface. When the end support rod 2 of the conveyor belt 1 flips to unload the material, the material 101 falls in a free fall or tumbling state. The two symmetrically arranged conveyor belts 22 are connected to the end of the conveyor belt 1 by the belt 23, forming a seamless receiving platform. The support plate 24 on the surface of the conveyor belt 22 provides support for the material 101 the moment it falls, avoiding end deformation, surface bumps or structural damage caused by the material 101 directly hitting the ground or downstream equipment. At the same time, the continuous operation of the conveyor belt 22 smoothly changes the material 101 from the ring-shaped lifting posture of the conveyor belt 1 to the horizontal conveying posture, realizing a flexible transition of the posture of the material 101 and ensuring the integrity of the easily rolling rod-shaped material 101. Meanwhile, the pallet 24 lifts the received material 101 one by one, and a fixed physical interval is formed between adjacent pallets 24, so that each material 101 remains independent on the conveyor belt 22. This reduces the possibility of the material 101 rolling due to inertia, colliding with each other, or piling up and squeezing after falling from the end of the conveyor belt 1. At the same time, the isolation of the material 101 provides a clear and identifiable position of the material 101 for subsequent processes such as robot picking, manual sorting, or automatic palletizing, which helps to improve the efficiency and accuracy of downstream operations.

[0031] Reference Figure 8 The end surface of the support rod 2 is provided with multiple rotating grooves, and each rotating groove is provided with a ball bearing 25. The multiple rotating grooves and the ball bearing 25 on the end surface of the support rod 2 transform the original sliding friction between the support rod 2 and the outer surface of the rod-shaped material 101 into rolling friction between the ball bearing 25 and the material 101. The frictional resistance is reduced, allowing the material 101 to move more smoothly relative to the end of the support rod 2, and reducing the scratching damage of the label on the surface of the material 101 by the support rod 2.
