Description

Technical Field

[0001] This invention relates to the field of tobacco logistics technology, and in particular to a pallet integrated inspection system, method, medium, and program product. Background Technology

[0002] In the tobacco industry's cigarette production and logistics system, finished product pallets are the basic unit for carrying and transferring cigarette products. Each finished product pallet is equipped with a unique RFID chip and pallet barcode, and the binding relationship between the two must be registered in the WMS (Warehouse Management System) before being put into circulation. After the finished cigarettes are sold and circulated by commercial companies, the pallets need to be recycled and reused in production. Currently, in the pallet recycling process, the RFID chip information bound to the finished product pallets returned by commercial companies often does not match the binding relationship recorded in the WMS system. This causes the automated guided vehicles or stacker cranes in the stacking process to be unable to correctly identify the pallets, resulting in stacking failures and production line stoppages. Furthermore, after frequent loading, unloading, transportation, and stacking by commercial companies, finished product pallets are prone to structural damage such as missing corners, cracks, and deformation. These problems often only become apparent in the stacking process, by which time the problematic pallets have already entered the production process, requiring machine shutdown for processing, resulting in a double waste of time and manpower.

[0003] In existing technologies, the binding verification of trays mainly relies on manual visual inspection. Operators use handheld terminals to scan barcodes and read chip information for verification. Furthermore, the detection of tray appearance defects also relies on manual observation, lacking standardized detection methods. Summary of the Invention

[0004] This invention provides a comprehensive pallet inspection system, method, medium, and program product to solve the problems of high labor costs and low efficiency in manually inspecting pallet information and appearance on pallets transferred back from outside the system.

[0005] According to one aspect of the present invention, a pallet integrated inspection system is provided, comprising: Radio frequency identification (RFID) reading components, barcode scanner components, vision inspection modules, and target control modules; Among them, the radio frequency identification reading component, the barcode scanner component, and the vision inspection module are communicatively connected to the target control module; The radio frequency identification (RFID) reading component is used to read the RFID chip encoding information of the current tray and send the RFID chip encoding information to the target control module. The barcode scanner component is used to read the pallet barcode of the current pallet and send the pallet barcode of the current pallet to the target control module; The visual inspection module is used to acquire an image of the current pallet's appearance and send the image to the target control module. The target control module is used to send the radio frequency chip encoding information and pallet barcode of the current pallet to the warehouse management system for consistency verification, and to monitor pallet appearance defects based on the pallet appearance image of the current pallet. When the current pallet passes the consistency verification and has no appearance defects, the current pallet is transferred to the stacking station.

[0006] According to another aspect of the present invention, a pallet comprehensive inspection method is provided, which is executed by the target control module of the pallet comprehensive inspection system in any embodiment; The RFID chip encoding information and pallet barcode of the current pallet are sent to the warehouse management system for consistency verification. The pallet appearance defect is monitored based on the pallet appearance image of the current pallet. When the current pallet passes the consistency verification and has no appearance defects, the current pallet is transferred to the stacking station.

[0007] According to another aspect of the present invention, a target control module is provided, the target control module comprising: At least one processor; and a memory communicatively connected to said at least one processor; The memory stores a computer program that can be executed by the at least one processor, which is then executed by the at least one processor to enable the at least one processor to perform the tray comprehensive detection method according to any embodiment of the present invention.

[0008] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions for causing a processor to execute and implement the tray comprehensive detection method according to any embodiment of the present invention.

[0009] According to another aspect of the present invention, a computer program product is provided, the computer program product comprising a computer program that, when executed by a processor, implements the tray comprehensive detection method according to any embodiment of the present invention.

[0010] The technical solution of this invention constructs a comprehensive pallet inspection system through an RFID reader component, a barcode scanner component, a vision inspection module, and a target control module. The target control module in the comprehensive pallet inspection system sends the RFID chip encoding information of the current pallet collected and transmitted by the RFID reader component, and the pallet barcode of the current pallet collected and transmitted by the barcode scanner component, to the warehouse management system for consistency verification. Based on the vision inspection module's determination that the current pallet has no appearance defects, the current pallet is then transferred to the pallet stacking station. This solution can simultaneously perform information consistency verification and appearance defect detection on pallets returned from external circulation without manual intervention, greatly reducing manpower and solving the problems of high labor costs and low efficiency associated with manual pallet information inspection and appearance detection on pallets returned from external circulation. It can automatically perform pallet information inspection and appearance detection on pallets returned from external circulation, saving labor costs.

Detailed Implementation

[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0015] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0016] Example 1 Figure 1 This is a schematic diagram of a pallet integrated inspection system provided in Embodiment 1 of the present invention. Figure 1 As shown, the system may include: an RFID reader component, a barcode scanner component, a vision inspection module, and a target control module; wherein, the RFID reader component, the barcode scanner component, and the vision inspection module are communicatively connected to the target control module; the RFID reader component is used to read the RFID chip encoding information of the current pallet and send the RFID chip encoding information to the target control module; the barcode scanner component is used to read the pallet barcode of the current pallet and send the pallet barcode of the current pallet to the target control module; the vision inspection module is used to acquire the pallet appearance image of the current pallet and send the pallet appearance image of the current pallet to the target control module; the target control module is used to send the RFID chip encoding information and the pallet barcode of the current pallet to the warehouse management system for consistency verification, and to monitor pallet appearance defects based on the pallet appearance image of the current pallet. When the current pallet passes the consistency verification and has no appearance defects, the current pallet is transferred to the stacking station.

[0017] The RFID reading component can be a component that reads information recorded in an RFID chip. The RFID chip encoding information can be information recorded on the RFID chip. For example, the RFID chip encoding information can include, but is not limited to, basic RFID identifiers (chip serial number and pallet identification code), checksum, basic pallet asset information (pallet asset number, pallet specifications, pallet ownership information, production date, maximum load capacity), and cargo and warehousing circulation business information (currently loaded cargo information, inbound and outbound records, transportation logistics information, stacking restriction markings, etc.). The barcode scanner component can be a component that scans barcodes affixed to the pallet. The visual inspection module can be a component that captures images of the pallet's appearance within its field of view. The visual inspection module can include industrial cameras or laser contour scanners. Laser contour scanners determine whether there are missing corners or deformations by measuring the three-dimensional contour data of the pallet's shape. The target control module can be the core control component of the integrated pallet inspection system. Pallet appearance defect monitoring can be an operation that detects appearance defects in pallets based on images of the pallet's appearance. Optionally, pallet appearance defect monitoring can be used to identify pallets with missing corners, cracks, and deformation.

[0018] In this embodiment of the invention, a comprehensive pallet inspection system can be built using an RFID reader component, a barcode scanner component, a vision inspection module, and a target control module. The target control module in the comprehensive pallet inspection system is communicatively connected to the RFID reader component, the barcode scanner component, the vision inspection module, and the target control module, respectively. The RFID reader component reads the RFID chip encoding information of the current pallet and sends it to the target control module. The barcode scanner component reads the pallet barcode of the current pallet and sends it to the target control module. The vision inspection module captures an image of the current pallet's appearance and sends it to the target control module. The target control module can send the RFID chip encoding information and the pallet barcode of the current pallet to the warehouse management system for consistency verification. Specifically, the warehouse management system determines whether the RFID chip encoding information and the bound pallet barcode of the current pallet are consistent with the information of the current pallet recorded locally. The pallet appearance image is then input into a pre-trained target detection model to monitor for pallet appearance defects. When the current pallet passes the consistency verification and has no appearance defects, it is considered a qualified pallet and is transferred to the pallet stacking station for transfer to the production line.

[0019] The pre-trained target detection model can be YOLO or Faster R-CNN (faster region convolutional neural network) pre-trained on images of trays with defects such as missing corners, cracks, and deformation.

[0020] The technical solution of this invention constructs a comprehensive pallet inspection system through an RFID reader component, a barcode scanner component, a vision inspection module, and a target control module. The target control module in the comprehensive pallet inspection system sends the RFID chip encoding information of the current pallet collected and transmitted by the RFID reader component, and the pallet barcode of the current pallet collected and transmitted by the barcode scanner component, to the warehouse management system for consistency verification. If the consistency verification is passed, and the vision inspection module determines that the current pallet has no appearance defects, the current pallet is transferred to the pallet stacking station. This solution can simultaneously perform information consistency verification and appearance defect detection on pallets returned from external circulation without manual intervention, greatly reducing manpower and solving the problems of high labor costs and low efficiency in manually inspecting pallet information and appearance on pallets returned from external circulation. It can automatically perform pallet information inspection and appearance detection on pallets returned from external circulation, saving labor costs.

[0021] Example 2 Embodiment 2 of the present invention provides a specific implementation of the pallet integrated inspection system, which can be referred to in the following embodiments. Technical terms that are the same as or corresponding to those in the above embodiments will not be repeated here.

[0022] In an optional embodiment of the present invention, the pallet integrated inspection system may include: a pallet conveying mechanism; the pallet conveying mechanism includes a transmission channel and a diversion mechanism; the transmission channel includes a main conveying channel, a first branch channel and a second branch channel; the diversion mechanism includes a start-up push rod or an electric steering wheel; an RFID reading component and a barcode scanner component are symmetrically installed on both sides of the main conveying channel; when the current pallet passes the consistency check and has no appearance defects, the current pallet is conveyed to the stacking station through the first branch channel; when the current pallet fails the consistency check and / or has appearance defects, the current pallet is conveyed to the abnormal handling area through the second branch channel.

[0023] The pallet conveying mechanism can be a conveyor for pallet circulation. The conveying channel can be a continuous conveyor that drives goods forward. The conveying channel may include a powered roller conveyor. The main conveying channel can be a channel for conveying unidentified pallets. The first branch channel can be a channel for conveying qualified pallets identified by the target control module. The second branch channel can be a channel for conveying unqualified pallets identified by the target control module. The diversion mechanism can be a powered mechanism that pushes pallets to different branch channels. The exception handling area can be an area for collecting unqualified pallets. See [link to relevant documentation] for the positional relationship between the conveying channel and the diversion mechanism. Figure 2 .

[0024] In this embodiment of the invention, the pallet conveying mechanism of the pallet integrated inspection system may include a transmission channel and a diversion mechanism. The diversion mechanism is installed at the junction of the main conveying channel and the branch channels (the first branch channel and the second branch channel), and the RFID reading component and the barcode scanner component are symmetrically installed on both sides of the main conveying channel. When the current pallet passes the consistency check and has no appearance defects, the target control module controls the diversion mechanism to divert the current pallet to the first branch channel, so that the current pallet is conveyed to the stacking station through the first branch channel. When the current pallet fails the consistency check and / or has appearance defects, the target control module controls the diversion mechanism to divert the current pallet to the second branch channel, so that the current pallet is conveyed to the abnormal handling area through the second branch channel.

[0025] In an optional embodiment of the invention, the visual inspection module includes at least two industrial cameras; the barcode scanner assembly may include a one-dimensional barcode scanner and / or a two-dimensional barcode scanner.

[0026] A one-dimensional barcode scanner can be a scanner that scans one-dimensional barcodes. A two-dimensional barcode scanner can be a scanner that scans two-dimensional barcodes.

[0027] In this embodiment of the invention, the visual inspection module can be installed above and to the side of the visual inspection station on the main conveying channel.

[0028] In an optional embodiment of the present invention, the pallet integrated detection system further includes a pallet position adjustment component.

[0029] The pallet position adjustment component can be used to adjust the position of the pallet. For example, when the transmission channel is a powered roller conveyor, the pallet position adjustment component may include a lifting device installed at the end of the roller.

[0030] In this embodiment of the invention, when the current pallet enters the visual inspection station, the current pallet is limited, and the tilt angle of the corresponding main conveyor channel is adjusted by the pallet pose adjustment component so that the visual inspection module can collect multi-angle images of the pallet.

[0031] In an optional embodiment of the present invention, the pallet comprehensive inspection system further includes: an alarm module; the alarm module is communicatively connected to the target control module; the alarm module is used to issue an early warning when the target control module detects that the current pallet has failed the consistency check and / or has appearance defects.

[0032] The alarm module may include a buzzer and a warning light.

[0033] In this embodiment of the invention, when the pallet comprehensive inspection system is equipped with an alarm module, the alarm module can be connected to the target control module for communication. When the target control module detects that the current pallet has not passed the consistency check and / or has appearance defects, it triggers the alarm module to issue an early warning.

[0034] In an optional embodiment of the present invention, the pallet integrated inspection system may further include: a display module; the display module is communicatively connected to the radio frequency identification reading component, the barcode scanner component, and the vision inspection module; the display module is used to display the radio frequency chip encoding information, the pallet barcode, and the pallet appearance image of the current pallet.

[0035] The display module may include an industrial touchscreen, installed near the pallet inspection station on the main conveyor channel. The RFID reader, barcode scanner, vision inspection module, and target control module are separated into independent workstations, with the RFID verification station, barcode scanning station, and vision inspection station arranged sequentially and connected in series via a conveyor line.

[0036] In this embodiment of the invention, if the pallet integrated inspection system also includes a display module, the display module can be communicatively connected to the RFID reading component, the barcode scanner component, and the vision inspection module to display the RFID chip encoding information of the current pallet, the pallet barcode, and the pallet appearance image. The display module can also be used to display relevant information about historically inspected pallets.

[0037] In a specific example, the pallet integrated inspection system is set up on the production line after the barcode scanning station and before the stacking station.

[0038] Pallet conveying mechanism: Composed of a conveying channel and a diversion mechanism, including a main conveying channel and two branch channels. The first branch channel connects to the stacking station, and the second branch channel connects to the exception handling area. The diversion mechanism uses pneumatic push rods or electric steering wheels, and its direction of movement is controlled by the target control module based on the judgment result.

[0039] The RFID reading component uses an ultra-high frequency RFID reader / writer, operating at a frequency of 860-960MHz, with a reading distance of 0-100cm. It is positioned below or to the side of the pallet's travel path. When the pallet passes the inspection station, it automatically reads the RFID chip encoding information on the pallet.

[0040] The barcode scanning component is set above the corresponding inspection station to scan the barcode affixed to the side or top surface of the pallet and obtain the pallet barcode.

[0041] The vision inspection module includes at least two industrial cameras, mounted above and to the side of the inspection station, respectively, to acquire multi-angle images of the upper and side surfaces of the pallet. The cameras have a resolution of at least 5 megapixels and are equipped with complementary illumination sources.

[0042] The target control module may include a programmable logic controller or an industrial control computer. The target control module has a built-in communication unit that interacts with the WMS system via industrial Ethernet.

[0043] A comprehensive pallet inspection method is executed by the target control module in any embodiment of the comprehensive pallet inspection system. For example... Figure 3 As shown, the comprehensive pallet inspection method includes: sending the radio frequency chip encoding information and pallet barcode of the current pallet to the warehouse management system for consistency verification, and monitoring pallet appearance defects based on the pallet appearance image of the current pallet; when the current pallet passes the consistency verification and has no appearance defects, the current pallet is transferred to the stacking station.

[0044] In a specific example, the comprehensive pallet inspection method includes the following key steps: 1) The tray with the completed chip barcode binding is transported to the testing station via the main conveyor channel.

[0045] 2) The RFID reading component reads the RFID chip encoding information, and the barcode scanner component scans the tray barcode.

[0046] 3) The target control module sends the RF chip encoding information and the tray barcode to the WMS system through the communication unit for consistency comparison and verification, and receives the comparison results returned by the WMS system.

[0047] 4) The industrial camera of the vision inspection module captures images of the pallet's appearance and sends them to the target control module.

[0048] 5) If the comparison result returned by the WMS system is a match and the pallet has no appearance defects, it is judged as a qualified pallet, and the target control module controls the diversion mechanism to transport the pallet to the stacking station; if the comparison result returned by the WMS system is a mismatch and / or there are appearance defects, it is judged as a non-qualified pallet, and the target control module controls the diversion mechanism to transport the pallet to the abnormal handling area, while driving the alarm module to issue an audible and visual alarm.

[0049] 6) The display module updates and displays the test results in real time, and all data is automatically stored for subsequent traceability.

[0050] By integrating RFID verification, barcode scanning, and visual inspection into a single device after the binding station, problematic pallets are identified and intercepted before entering the palletizing process, avoiding palletizing interruptions caused by binding mismatch or pallet damage. Real-time WMS data comparison ensures system data consistency, deep learning visual inspection enables automatic and accurate identification of pallet appearance defects, and automatic diversion and alarm mechanisms reduce the need for manual intervention.

[0051] The integrated design consolidates the three main functions, simultaneously completing all inspection items with maximum efficiency and minimal footprint. Real-time WMS verification ensures system data consistency, while deep learning-based visual inspection can identify complex appearance defects.
