[0002] In the digital traceability system of the food and beverage industry, one-item-one-code technology has been widely used in product lifecycle management.

[0003] In the process of connecting existing palletizer signals with the one-item-one-code factory system, after the palletizer completes palletizing of whole pallets or individual pallets, it is necessary to manually judge the palletizing status and the number of individual pallets, and manually trigger the coding and traceability process of the one-item-one-code system, which is inefficient.

[0015] After associating the zero-pallet identification code with the product information, a zero-pallet transfer instruction is generated and sent to the execution module, so that the execution module, based on the zero-pallet transfer instruction, transports the current pallet to the scattered sorting area or temporary storage area.

[0016] According to the present invention, a whole and empty pallet coding control device based on palletizer signal linkage is provided, wherein the acquisition module includes a counting detection submodule, a product information identification submodule and a position detection submodule;

[0018] The product information identification submodule is used to scan the identification code of the grabbed boxed products in the current round of palletizing operation and collect the product information of each boxed product in the current round of palletizing operation.

[0019] The position detection submodule is used to determine whether the current pallet has been delivered to the palletizing completion position. If the current pallet is detected to be at the palletizing completion position, the palletizing completion signal is triggered.

[0020] The present invention provides a control device for assigning codes to palletizers based on signal linkage of a palletizer, which further includes: a signal interface module;

[0021] The signal interface module is disposed between the palletizer unit and the main control module, and the signal interface module is used for:

[0035] Figure 2 This is a schematic diagram of the control and management process provided by the present invention.

[0036] Figure 3 This is a schematic diagram of the structure of the whole and part pallet coding control system for signal linkage of palletizer provided by the present invention. Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0038] In the digital traceability system of the food and beverage industry, one-item-one-code technology has been widely used in product lifecycle management. However, in related methods, the one-item-one-code factory system and the palletizing equipment in the production process mostly operate independently, lacking an effective signal linkage mechanism.

[0039] After the palletizer completes palletizing of whole pallets or individual pallets, the palletizing status and the number of individual pallets need to be judged manually, and the coding and traceability process of the one-item-one-code system needs to be manually triggered. This is inefficient and prone to human error.

[0040] Furthermore, the one-item-one-code system cannot obtain the real-time operating status of the palletizer (such as palletization completion, number of pallets, and palletization type), resulting in a mismatch between the assigned code and the actual palletization status. This leads to problems such as assigning codes to whole pallets but missing codes to empty pallets, and inaccurate quantities of boxes inside scattered pallets, affecting the integrity of the traceability chain.

[0041] In addition, the relevant methods lack dynamic control over the circulation process of whole pallets or individual pallets, and cannot automatically adjust the coding rules and traceability dimensions according to the palletizing status, thus lacking the ability to adapt to the needs of flexible production.

[0042] To address the shortcomings of related methods, this invention provides a whole-and-minimum pallet coding control device based on palletizer signal linkage. Figure 1 This is a schematic diagram of the structure of the whole and part pallet coding control device based on palletizer signal linkage provided by the present invention, as shown below. Figure 1 As shown, the device includes a palletizer unit 110 and a main control module 120.

[0043] The palletizer unit is connected to the main control module. The palletizer unit is an automated device at the end of the production line responsible for stacking individual boxed products onto pallets. The current palletizing operation constitutes one work cycle for the palletizer unit.

[0044] During a work cycle, the palletizer unit operates continuously until a pallet is full or all products in the current batch are processed. During this process, the palletizer unit acquires the cumulative number of products in the current palletizing cycle and the product information for each carton of products in the current palletizing cycle.

[0045] Data acquisition methods for palletizing units can be varied. For example, the palletizing unit can integrate or connect external sensors to monitor its operation in real time. The cumulative number of products can be obtained by installing counting sensors (such as photoelectric sensors) on the product conveyor belt; each time a boxed product is picked up by the robotic arm of the palletizing unit, the counter increments by one. Product information can be collected by installing industrial barcode scanners along the picking path of the palletizing unit. The scanners read the unique identification code (such as a QR code or barcode) on the outer packaging of each boxed product, thereby obtaining various information associated with that boxed product.

[0046] After the current round of palletizing operations is completed, the palletizer unit outputs a palletizing completion signal to the main control module. This signal can indicate that the cumulative number of products has reached a standard full pallet quantity; or that the current pallet has been moved to the palletizing completion station; or that a batch production end command has been received from a higher-level system, such as a production execution system. The palletizing completion signal can be a level signal, a switch signal, or a message transmitted via an industrial bus.

[0047] The main control module can be a standalone industrial control computer or server, or a core functional module integrated into a one-item-one-code factory system. The one-item-one-code factory system is a digital production management and control platform that enables automated and intelligent one-item-one-code traceability and full-process control.

[0048] The main control module, acting as the decision-making and control center for the entire coding control logic, responds to the palletizing completion signal sent by the palletizer unit. Upon receiving the palletizing completion signal, the main control module initiates the judgment and execution of the coding process.

[0049] The main control module compares the cumulative product quantity received or obtained through the palletizer unit with a preset pallet-filling threshold, and determines whether the current palletizing operation results in a full pallet or a zero pallet based on the comparison result. The pallet-filling threshold is a pre-configurable parameter that represents the number of boxes of product that a standard full pallet should contain. For example, in the production of a certain specification of liquid milk, a standard pallet can hold 24 boxes of product, so the pallet-filling threshold here can be set to 24.

[0050] The comparison process is a numerical comparison. If the cumulative number of products equals the full pallet determination threshold, the main control module determines the current palletizing status as full pallet. If the cumulative number of products is less than the full pallet determination threshold, the main control module determines the current palletizing status as zero pallet. Typically, the zero pallet status occurs at the end of a batch production, when the remaining products are insufficient to fill a standard pallet.

[0051] If the current palletizing status is determined to be a full pallet based on the comparison results, the main control module will automatically generate a unique full pallet identification code and associate this full pallet identification code with the product information of all boxed products collected in this round of palletizing operation, thereby obtaining the coding information for the current round of palletizing operation.

[0052] If the current palletizing status is determined to be zero pallet based on the comparison results, the main control module will generate a unique zero pallet identification code. Similarly, the zero pallet identification code will be associated with the product information of all boxed products that are less than one full pallet collected in this round of operation to obtain the corresponding coding information.

[0053] It should be noted that a "full pallet" refers to a pallet containing a pre-set, standard quantity of products. A "zero pallet" refers to a pallet containing fewer products than the standard quantity.

[0054] It's important to note that when product quality issues necessitate recalls, if the data is accurate, the factory can pinpoint and handle the issue down to the pallet level. Confusing full pallets and partial pallets could lead to an expanded recall scope (mistaking partial pallets for full pallets, recalling unnecessary products) or a narrowed scope (mistaking full pallets for partial pallets, missing necessary products), severely impacting the efficiency and reliability of traceability. Furthermore, the warehouse management system needs to execute different storage and transportation management processes based on whether it's a full pallet or partial pallet. Data for every product, every box, and every pallet on the production line is collected in real time for calculating production volume and inventory statistics. Accurate identification of full pallets and partial pallets is fundamental to ensuring the accuracy of production and inventory data.

[0055] Full pallet identification codes and partial pallet identification codes are digital codes used to uniquely identify a physical pallet and the goods it carries. Their coding rules can be predefined; for example, they can use the format of factory code + production line number + production date + batch number + pallet serial number. For differentiation, partial pallet identification codes can add a special identifier to this format. The process of associating full pallet identification codes or partial pallet identification codes with products essentially establishes a relationship at the data level, that is, the correspondence between a pallet code and all the box codes on that pallet. The final generated coding information is this structured data set, completely recording all traceability information of a pallet and its contents.

[0056] Optionally, the control and management process implemented by the palletizer signal linkage-based whole and part pallet coding control device can be as follows: Figure 2 The control and management process diagram provided by this invention is shown.

[0057] The initial setup involves the main control module setting a pallet threshold, such as 24 boxes per pallet. When the palletizer unit performs palletizing operations, the data acquisition module counts and collects box number information in real time.

[0058] After the operation is completed, the palletizer unit generates a palletizing completion signal. The main control module receives this signal and compares the actual number of products palletized with a preset threshold to automatically determine whether the current palletizing status is a full pallet or a zero pallet.

[0059] If the pallet is in full condition: the main control module will generate a unique pallet identification code, associate it with the box code information of all products in the pallet, and instruct the execution module to transport the pallet to the full pallet storage area.

[0060] If the pallet is in zero-pallet status: the main control module will generate a zero-pallet identification code and instruct the execution module to transport the pallet to the scattered sorting area or temporary storage area.

[0061] While the conveying process is underway, on-site control operations are performed, and the generated pallet identification code and associated product information are uploaded to the traceability platform and warehouse management system to complete the warehousing and data closure, ultimately achieving precise and automated intelligent control of whole and individual pallets.

[0062] The present invention provides a pallet-based coding control device for whole and single pallets, which achieves automated integration of the physical palletizing operation and the coding information flow by setting up interconnected palletizing machine units and a main control module. After the palletizing operation is completed, the main control module can respond to the palletizing completion signal actively output by the palletizing machine unit, and automatically compare it with the whole pallet judgment threshold based on the acquired cumulative product quantity, thereby accurately determining whether the current palletizing state is whole pallet or single pallet. On this basis, the main control module can automatically generate the corresponding whole pallet identification code or single pallet identification code and complete the association with product information, avoiding the processing delay and misjudgment risk caused by manual intervention. While ensuring coding accuracy, it significantly improves the overall coding efficiency in mixed whole and single pallet production scenarios.

[0063] In one embodiment, the palletizer unit includes a data acquisition module and an execution module;

[0064] The execution module is used to stack boxed products onto the current pallet in the current round of palletizing operation;

[0065] The acquisition module is used to determine the cumulative number of products in the current round of palletizing operations and to acquire product information of each boxed product in the current round of palletizing operations. After the current round of palletizing operations is completed, it outputs a palletizing completion signal to the main control module.

[0066] Specifically, the execution module is the part of the palletizer unit that performs physical operations. Its core function is to stack boxed products one by one onto the current pallet according to a preset stacking pattern in the current palletizing operation. In a specific implementation, the execution module can be a palletizer of an industrial robot, which includes a robotic arm, grippers, and other structures.

[0067] The data acquisition module is the part of the palletizer unit responsible for data acquisition and signal generation. It is used to determine the cumulative number of products in the current round of palletizing operation, collect product information of each boxed product, and output a palletizing completion signal to the main control module after the operation is completed.

[0068] By separating the physical execution and data acquisition functions into two different modules, the structure of the device becomes clearer and the logic more explicit.

[0069] In one embodiment, the main control module is further configured to:

[0070] After associating the pallet identification code with the product information, a pallet entry instruction is generated and sent to the execution module, so that the execution module delivers the current pallet to the pallet storage area based on the pallet entry instruction.

[0071] A full pallet receiving instruction is a control command that instructs the execution module or its cooperating conveyor system to proceed with the next physical transfer of a fully tagged pallet. Upon receiving this instruction, the execution module performs the corresponding operation, transporting the current pallet carrying the full stack of products to a pre-planned full pallet storage area. This storage area can be a dedicated area within the warehouse for storing standard full pallets. For example, the execution module can control the conveyor belt beneath the pallet to start, transporting the pallet to a designated warehouse entrance.

[0072] The pallet coding control device based on palletizer signal linkage provided by this invention can seamlessly trigger automatic warehousing instructions after automatically completing the identification and coding of the whole pallet, realizing the fully automated closed-loop control from palletizing, coding to warehousing, further reducing manual operation and improving the efficiency and accuracy of warehouse management.

[0073] In one embodiment, the main control module is further configured to:

[0074] After associating the zero-pallet identification code with the product information, a zero-pallet transfer instruction is generated and sent to the execution module, so that the execution module, based on the zero-pallet transfer instruction, transports the current pallet to the scattered sorting area or temporary storage area.

[0075] The zero-pallet transfer instruction is a control command for zero pallets. After receiving the zero-pallet transfer instruction, the execution module will transport the current pallet carrying the loose products to the loose sorting area or temporary storage area based on the instruction.

[0076] The loose sorting area can be used to recombine or consolidate these loose boxes. The temporary storage area can be used to temporarily store these loose pallets, awaiting further processing.

[0077] In one embodiment, the acquisition module includes a counting detection submodule, a product information recognition submodule, and a location detection submodule;

[0078] The counting and detection submodule is used to detect the boxed products being grabbed in the current round of palletizing operation, and to count and accumulate the detected boxed products to obtain the cumulative product quantity.

[0079] The product information identification submodule is used to scan the identification code of the grabbed boxed products in the current round of palletizing operation and collect the product information of each boxed product in the current round of palletizing operation.

[0080] The position detection submodule is used to determine whether the current pallet has been delivered to the palletizing completion position. If the current pallet is detected to be at the palletizing completion position, the palletizing completion signal is triggered.

[0081] Specifically, the counting and detection submodule is used to detect the boxed products being grabbed in the current round of palletizing operations and to accumulate the count of the detected boxed products to obtain the cumulative product quantity. In practice, the counting and detection submodule can be a photoelectric sensor installed in front of the palletizing robot's gripping path. Each time a boxed product passes by, the sensor generates a pulse signal, and the counter increments by one.

[0082] The product information recognition submodule is used to scan the identification codes of the boxed products being grasped during the current round of palletizing operations to collect product information. Specifically, the product information recognition submodule can be a fixed industrial barcode scanner or integrated into the robot's gripper. During the robot's grasping or transport of the box, the scanner automatically reads the identification codes on the box.

[0083] The position detection submodule determines whether the current pallet has been delivered to the palletizing completion position. When the pallet is detected to be at the palletizing completion position, the position detection submodule triggers the generation of a palletizing completion signal. Specifically, the position detection submodule can be a limit switch or a proximity sensor. When an empty pallet or a pallet that has been palletized is delivered to the designated station, the limit switch is triggered, thereby generating the palletizing completion signal.

[0084] The whole and part pallet coding control device based on palletizer signal linkage provided by this invention can accurately and in real time complete product counting, information collection and status judgment through the coordinated work of photoelectric sensors, barcode scanners and limit switches. It provides input data for the decision-making of the main control module and ensures the reliability of the entire automated control process.

[0085] In one embodiment, it further includes: a signal docking module;

[0086] The signal interface module is disposed between the palletizer unit and the main control module, and the signal interface module is used for:

[0087] The system receives the raw electrical signal output by the acquisition module, the raw electrical signal including a pulse signal representing the cumulative product quantity and a switch signal representing the palletizing completion signal;

[0088] The original electrical signal is converted into a digital message, and the digital message is transmitted to the main control module.

[0089] The data acquisition modules (such as sensors and switches) of a palletizer unit typically output raw electrical signals, such as pulse signals representing the cumulative number of products (from photoelectric sensors) and switching signals representing the completion of palletizing (such as 24V DC high and low level signals from limit switches). These signals cannot be directly processed by the main control module, which is usually based on an IT architecture.

[0090] Therefore, the signal interface module receives these raw electrical signals, converts them into digital messages, and then transmits the digital messages to the main control module. This signal interface module can be an industrial gateway capable of acquiring field I / O signals and encapsulating them into standardized industrial Ethernet protocol messages, such as OpenPlatform Communications Unified Architecture (OPC UA) or Modbus Transmission Control Protocol / Internet Protocol (Modbus TCP / IP). The main control module receives these standardized digital messages via the network, thereby achieving decoupling and interoperability with field devices.

[0091] The present invention provides a palletizer signal linkage-based whole and part pallet coding control device, which solves the communication problem between heterogeneous devices by introducing a signal interface module and a standardized communication protocol. It converts the physical signals on site into digital language that the information system can understand, greatly enhancing compatibility, scalability, and deployment flexibility.

[0092] In one embodiment, the main control module is further configured to:

[0093] Listen to the data packets of the signal interface module;

[0094] If no data packet is received within a preset time period, or if the signal quality during the data packet reception process is lower than a preset signal quality threshold, a pause operation instruction is generated and sent to the execution module, causing the execution module to stop the palletizing operation.

[0095] The main control module listens for data packets sent by the signal interface module. The main control module continuously checks the communication status with the signal interface module at a high frequency.

[0096] In two abnormal situations, the main control module will take action: First, if no data packets are received within a preset time period (e.g., 500ms), this may be due to communication interruption or equipment failure; second, if the signal quality of the received data packets is found to be lower than the preset signal quality threshold through methods such as packet verification, this may be due to data distortion.

[0097] In the event of an anomaly, the main control module generates a pause command and sends it to the execution module, causing the execution module to stop the palletizing operation. Simultaneously, the system can trigger an audible and visual alarm to alert on-site personnel to inspect and handle the situation until communication is restored.

[0098] The palletizing control device based on palletizer signal linkage provided by this invention achieves closed-loop monitoring of the health status of the communication link by establishing a communication heartbeat monitoring and anomaly handling mechanism. In the event of an anomaly, the operation can be stopped promptly, effectively avoiding serious production accidents such as coding errors and mismatches between product information and pallets caused by data errors or loss, thus ensuring production safety and data accuracy.

[0099] In one embodiment, the product information includes box code information, production batch number, production date, and production line number.

[0100] Among these, the box code is a unique identification code printed or affixed to each boxed product, serving as the basic unit for one-item-one-code traceability. The production batch number, production date, and production line number provide the product's production background information, recording the crucial context of when, where, and from which batch the boxed product was produced. Together, this information constitutes a complete identity file for a product.

[0101] In one embodiment, the main control module is further configured to:

[0102] If the current palletizing status is determined to be a full pallet status, a mapping relationship is established between the full pallet identification code and the box code information, the production batch number, the production date, and the production line number, and the mapping relationship is uploaded to the database;

[0103] If the current palletizing status is determined to be zero pallets, a mapping relationship is established between the pallet identification code and the box code information, the production batch number, the production date, and the production line number, and the mapping relationship is uploaded to the database.

[0104] It should be noted that the database can be the backend database of a one-item-one-code factory system or a factory-level traceability platform. Establishing a mapping relationship refers to building a structured data record in memory or a temporary file, clearly expressing the ownership relationship between the pallet and its contents. This mapping record is sent and stored in the central data platform via an Application Programming Interface (API) or other means, making it a traceable record. Subsequently, the platform can also push the data to an Enterprise Resource Planning (ERP) system or a Warehouse Management System (WMS).

[0105] The pallet coding control device based on palletizer signal linkage provided by this invention ensures the timeliness, integrity, and consistency of traceability data by uploading the real-time generated pallet association relationship to a database. This not only provides a reliable data source for post-event traceability but also provides data support for real-time decision-making in other enterprise management systems.

[0106] This invention also provides a whole-item pallet coding control system based on palletizer signal linkage. This system aims to achieve seamless integration and intelligent control between end-of-line palletizing and a one-item-one-code traceability system.

[0107] This system includes the aforementioned pallet coding control device based on palletizer signal linkage. Therefore, the system possesses all or some of the following functions: automatic identification of full / partial pallet status, automatic generation and association of pallet information, automated control of pallet flow, anomaly monitoring and handling, and data interaction with upper-level systems. As a whole, this system can be integrated into automated production lines in various food and beverage industries and other sectors, significantly improving their digitalization and intelligence levels.

[0108] Optionally, the whole and part pallet coding control system based on palletizer signal linkage can be as follows: Figure 3 The schematic diagram of the whole and part pallet coding control system linked to the palletizer signal provided by the present invention is shown.

[0109] The palletizing and order-assignment control system based on palletizer signal linkage uses a traceability system platform as its data interaction core. It interacts with the Enterprise Resource Planning (ERP) system for basic and order information exchange and synchronizes product, batch, and related data with the warehouse management system. At the production site level, the main control module connects to the traceability system platform via routing and communicates directly with the palletizer. The palletizer performs physical stacking and sends whole / part signals to the main control module. The main control module processes these signals, associates boxes with pallets, and sends instructions to the conveyor system, which then controls the physical conveyor line to deliver the finished product pallets into the warehouse. The entire architecture achieves automated closed-loop control from upper-level management to on-site execution through a network.

[0110] The device embodiments described above are merely illustrative. The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the modules can be selected to achieve the purpose of this embodiment according to actual needs. Those skilled in the art can understand and implement this without any creative effort.
