Description

Technical Field

[0001] This utility model relates to the technical field of tobacco logistics equipment, specifically to an RFID-based whole pallet cigarette warehousing scanning and association device. Background Technology

[0002] When irregularly shaped cigarettes leave the tobacco logistics center, they need to be packaged into cartons according to orders. Then, staff use handheld barcode scanners to scan each carton of cigarettes for shipment. However, during peak sales seasons for irregularly shaped cigarettes, the efficiency of scanning and shipping a single carton of cigarettes cannot meet the actual sorting and distribution needs. At the same time, the workload of scanning and shipping a single carton of cigarettes is large, resulting in high labor costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an RFID-based whole pallet cigarette inbound scanning and association device to solve the problems of low work efficiency and high labor costs when scanning irregularly shaped cigarette packs for outbound processing.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A RFID-based whole pallet cigarette inbound scanning and association device; it includes a pallet, an inbound terminal, and an outbound terminal;

[0006] The pallet is used to load cigarettes; an RFID electronic tag is attached to the pallet.

[0007] The warehousing terminal is a vertical structure; an RFID reader for reading RFID electronic tags is installed on the lower side surface of the terminal; the RFID reader also has a barcode scanner for scanning the QR codes on irregularly shaped cigarette packs; both the RFID reader and the barcode scanner are connected to the warehousing microprocessor via cables; the warehousing microprocessor has a wireless communication module; the warehousing microprocessor can access and read / write cloud databases through the wireless communication module.

[0008] The outbound terminal includes a main body, on which are electrically connected an outbound RFID reader and an outbound microprocessor; the outbound RFID reader is used to read RFID electronic tags; the outbound microprocessor is also equipped with a wireless communication module; the outbound microprocessor can access and read / write cloud databases through the wireless communication module.

[0009] Preferably, the RFID electronic tag on the pallet is set on one end face of its perimeter; the inbound terminal includes a stand; the inbound RFID reader is set on the stand at the same height as the RFID electronic tag on the pallet; and omnidirectional rollers with locking devices are provided at the bottom of the stand.

[0010] Furthermore, the scanner is a handheld QR code scanner; a card slot is provided on the top of the stand; the scanner can be placed in the card slot.

[0011] Furthermore, the RFID electronic tag on the pallet is positioned near the forklift hole; a positioning block that can be inserted into the forklift hole is also provided on the underside of the stand; the stand can rest against the side of the pallet through the positioning block, at which point the RFID reader and the RFID electronic tag are facing each other.

[0012] Preferably, the outbound terminal is a handheld component; the outbound terminal is powered by a battery built into the component.

[0013] The beneficial effects of this utility model are reflected in the following aspects:

[0014] 1. Through an innovative inbound barcode scanning and association mechanism, the QR code information on the entire pallet of irregularly shaped cigarette packs is batch-bound with the RFID electronic tag of the pallet in a cloud database. In the outbound process, staff only need to use a handheld outbound terminal to scan the RFID tag of the pallet once to complete the synchronous outbound operation of all cigarette packs on the entire pallet. This completely changes the inefficient traditional barcode scanning outbound mode, improves the work efficiency several times, and effectively solves the pain point that the efficiency of single-pack barcode scanning outbound cannot meet the actual sorting and distribution needs during the peak season of irregularly shaped cigarette sales.

[0015] 2. This device optimizes the repetitive barcode scanning operation that originally required each irregularly shaped cigarette into a single whole pallet association binding upon entry and a single whole pallet RFID scan upon exit. This greatly reduces the number of barcode scans and operation time for staff during the exit process, significantly reducing labor costs and alleviating the workload of staff.

[0016] 3. The inbound terminal adopts a vertical structure design and is equipped with universal casters with locking function for easy movement and positioning; the positioning block at the bottom can be inserted into the forklift hole of the pallet to ensure that the inbound terminal is reliably attached to the side of the pallet, while ensuring that the inbound RFID reader is accurately aligned with the RFID electronic tag on the pallet, ensuring the accuracy and reliability of data reading; the barcode scanner adopts a handheld design and is equipped with a card slot for convenient staff to flexibly access and scan the QR codes of cigarette packs.

[0017] 4. Both the inbound and outbound terminals have built-in microprocessors and wireless communication modules, enabling real-time access to and reading / writing of cloud databases. During inbound, the QR code information of each pack of cigarettes is associated with the RFID tag on the pallet. During outbound, the status information of the entire pallet of cigarettes can be quickly retrieved and updated by scanning the RFID tag, realizing centralized data management and efficient data flow.

[0018] 5. Portable and flexible outbound terminal: The outbound terminal is designed as a handheld device and powered by a built-in battery, making it easy and flexible to operate and very suitable for the needs of mobile operations in logistics warehouses. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Example:

[0024] Reference Figure 1 This embodiment provides an RFID-based whole pallet cigarette warehousing scanning and association device; it includes a pallet 1, an inbound terminal 2, and an outbound terminal 3;

[0025] Tray 1 is used to load cigarettes; an RFID tag 4 is installed on tray 1; this RFID tag 4 is preferably a passive ultra-high frequency (UHF) tag conforming to the ISO18000-6C standard, such as the Alien Higgs-9 or Impinj Monza R6 series, which has a long reading distance and good resistance to metal interference, and is fixed to a designated position on the side of the tray by durable industrial-grade adhesive or riveting.

[0026] The receiving terminal 2 is a vertical structure. An RFID reader 5 for reading RFID electronic tags 4 is installed on the lower side surface of the receiving terminal 2. A barcode scanner 6 for scanning QR codes on irregularly shaped cigarette packs is also installed on the receiving RFID reader 5. Both the receiving RFID reader 5 and the barcode scanner 6 are connected to the receiving microprocessor 7 via cables. The receiving microprocessor 7 is equipped with a wireless communication module, which allows it to access and write to a cloud database. The receiving RFID reader 5 can be an industrial-grade fixed UHF reader, such as the Impinj R420 or Zebra FX9600, which has stable high-power output and dense tag reading capabilities. The barcode scanner 6 uses a common handheld one-dimensional / two-dimensional laser or image scanning engine, such as the Honeywell N3680 or Zebra DS8178 series. The microprocessor 7 for receiving data can be an embedded industrial computer module, such as a Raspberry Pi Compute Module 4 or a processing core based on the ARM Cortex-A series, running a Linux or RTOS system, responsible for data reception, processing, execution of related logic, and communication with the cloud. The wireless communication module preferably supports 4G LTE Cat 1 or Cat 4 and is compatible with Wi-Fi (802.11 a / b / g / n / ac), such as the Quectel EC25 or Quectel EC21 series modules, ensuring stable network connectivity in the warehouse environment.

[0027] The outbound terminal 3 includes a main body, on which an outbound RFID reader 8 and an outbound microprocessor 9 are electrically connected. The outbound RFID reader 8 is used to read RFID electronic tags 4. The outbound microprocessor 9 also has a wireless communication module, which allows it to access and write to a cloud database. The outbound RFID reader 8 uses a handheld UHF RFID reader module with an integrated antenna, such as the ThingMagic M6e Nano or Zebra RFD8500, for easy integration into a handheld terminal. The outbound microprocessor 9 can use a moderately performing embedded processor, such as the NXP i.MX RT series or STMicroelectronics STM32MP1, to meet the needs of fast querying and data updates. Its wireless communication module also uses a 4GLTECat 1 and a Wi-Fi module.

[0028] An RFID tag 4 is mounted on one end face of the pallet 1; the inbound terminal 2 includes a stand 21; an inbound RFID reader 5 is mounted on the stand 21 at the same height as the RFID tag 4 on the pallet 1; and omnidirectional casters with locking mechanisms are provided at the bottom of the stand 21. The omnidirectional casters with locking mechanisms ensure easy movement and stable positioning on the warehouse floor.

[0029] The barcode scanner 6 is a handheld QR code scanner; a card slot 22 is provided on the top of the stand 21; the barcode scanner 6 can be placed in the card slot 22.

[0030] The RFID tag 4 on pallet 1 is positioned near the forklift hole; a positioning block 23 that can be inserted into the forklift hole is also provided on the underside of the stand 21; the stand 21 can rest against the side of the pallet 1 through the positioning block 23, at which time the RFID reader 5 is opposite to the RFID tag 4, and the distance between the RFID reader and the RFID tag is within the optimal reading range.

[0031] The outbound terminal 3 is a handheld component; it is powered by a battery built into the unit. The unit integrates a high-capacity rechargeable lithium battery (such as a lithium polymer battery with a capacity of ≥6000mAh) to ensure sufficient working time (typically ≥8 hours of continuous operation).

[0032] This device uses RFID tags attached to pallets. Upon warehousing, a scanner at the warehousing terminal scans the QR codes of all non-standard cigarette packs (typically 5-30 packs) placed on the pallet. Simultaneously, an RFID reader reads the RFID tags. The warehousing microprocessor uploads all the non-standard cigarette packs on the pallet and their corresponding RFID tags to a cloud server for binding. Upon retrieval, the device simply scans the RFID tags on the pallet using an RFID reader, allowing for the simultaneous retrieval of 5-30 packs of non-standard cigarettes from the entire pallet. The cloud database (e.g., based on MySQL, PostgreSQL, or cloud services such as AWS RDS / Azure SQL Database) has a dedicated table structure storing the mapping relationship between the pallet RFID tag ID and the QR code information of all associated cigarette packs, as well as the status of the cigarette packs (e.g., warehousing, in stock, retrieval, binding time, retrieval time, etc.). The warehousing microprocessor 7 and the retrieval microprocessor 9 communicate securely with the cloud database via protocols such as RESTful API or MQTT (e.g., HTTPS / TLS).

[0033] For detailed operating steps, please refer to the following process:

[0034] Upon receiving the cigarettes: Push the receiving terminal 2 next to the fully loaded pallet 1, insert the positioning block 23 and lock it, and automatically read the RFID tag on the pallet; remove the handheld barcode scanner 6, scan the QR code of each irregularly shaped cigarette pack one by one, and place the corresponding cigarette pack on the pallet; after scanning, confirm on the terminal, and the system will automatically bind the cigarette pack information to the pallet RFID tag; the binding information is uploaded to the cloud database, and after a successful association prompt, remove the terminal and the forklift will transport the cigarettes into the warehouse.

[0035] When leaving the warehouse: Hold the outbound terminal 3 close to the pallet 1 to be outbound and scan its RFID electronic tag 4; the terminal automatically sends the outbound instruction of the RFID tag of the pallet to the cloud; the cloud updates the status of all cigarettes associated with the RFID tag to "outbound" and records it.
