Description

Technical Field

[0001] This invention relates to the technical field of cardboard box production, and more specifically to a fully automated cardboard conveying system and method based on Internet of Things (IoT) transportation. Background Technology

[0002] Corrugated cardboard is made by corrugating base paper to form a wavy corrugated core, and then gluing linerboard to the top and bottom of the core with adhesive to form a thick sheet of paper. Generally, corrugated cardboard is thicker than 0.1mm and has a basis weight of 250g / m³. 2 The above describes how corrugated cardboard boxes are formed by folding corrugated cardboard to create a box structure. Corrugated cardboard boxes, with their superior performance and good processing properties, have gradually replaced wooden boxes and other transport packaging containers, becoming the mainstay of transport packaging.

[0003] Furthermore, with the rapid development of e-commerce, fast-moving consumer goods, and intelligent manufacturing industries, the market demand for corrugated boxes exhibits significant characteristics of diverse varieties, small batches, short lead times, and high customization. Currently, our company's corrugated cardboard production primarily utilizes a single-machine or semi-automated combination mode. Given the current market demand, our production model is no longer adequate for the high-quality development requirements of corrugated cardboard boxes. Additionally, our company has identified the following core pain points in corrugated cardboard production using a single-machine or semi-automated combination mode: The first pain point is poor process coordination: Corrugated cardboard production lines, printing and slotting machines, die-cutting machines, gluing machines and other equipment are independent of each other, and rely on manual transfer, connection and scheduling between processes. When changing orders, the machine needs to be stopped and the equipment parameters need to be manually adjusted, which is not only time-consuming and labor-intensive, but also prone to production interruption due to human error, which seriously restricts the improvement of production efficiency.

[0004] The second pain point is the silo of production data: the operating data, process parameters and energy consumption data of various equipment cannot be interconnected, production scheduling relies on manual experience, and it is difficult to balance order delivery time, equipment utilization and order change costs, resulting in low equipment utilization, large material loss and crude energy consumption control.

[0005] The third pain point is insufficient flexibility: Faced with an increasing number of customized orders, traditional equipment is slow to respond when switching box types and adjusting sizes, making it difficult to quickly adapt to the needs of orders with different specifications and printing patterns, and thus unable to meet customers' personalized packaging needs.

[0006] Therefore, in order to solve the above technical problems, our company has combined our existing single-machine or semi-automatic combination mode to establish a fully automatic cardboard conveying system based on Internet of Things transportation, which integrates the linkage control of the entire corrugated cardboard production line, intelligent logistics conveying and production data collaborative management. This system enables the corrugated cardboard production to operate with fewer people, higher efficiency and more flexible operation, in order to solve the technical bottlenecks of low process connection efficiency, difficult quality control and insufficient flexible production capacity under the traditional production mode, and meet the current market's high requirements for corrugated cardboard production. Summary of the Invention

[0007] This invention aims to provide a fully automated corrugated cardboard conveying system based on the Internet of Things (IoT), which integrates the linkage control of the entire corrugated cardboard production line, intelligent logistics conveying, and collaborative management of production data. This system enables corrugated cardboard production to achieve less manpower, higher efficiency, and more flexible operation, thereby solving the technical bottlenecks of low process connection efficiency, difficult quality control, and insufficient flexible production capacity in the traditional production model, and meeting the current market's high requirements for corrugated cardboard production.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: 1) A fully automated cardboard conveying system based on the Internet of Things (IoT), including: The first processing module is configured as a processing area for small-batch production of corrugated cardboard, in which corrugated cardboard is processed sequentially through digital printing, Aupai grooving, and rotary die-cutting to obtain corrugated cardboard. The second processing module is configured as a processing area for mass production of corrugated cardboard, in which corrugated cardboard is processed by multiple sets of printing, slotting and die-cutting machines to obtain corrugated cardboard. The intermediate conveyor linkage module is configured to receive corrugated cardboard produced in small batches in the first processing module and corrugated cardboard produced in large batches in the second processing module, so as to selectively transport and store all corrugated cardboard in a double-layer side-by-side manner. The packaging processing module is configured to receive corrugated cardboard stored in the intermediate conveying linkage module, integrate the corrugated cardboard and package it in a directional conveying manner. The Internet of Things (IoT) control module is configured to enable data interaction and instruction transmission between the first processing module, the second processing module, the intermediate conveyor linkage module, and the packaging processing module via a wireless network. This allows the first and second processing modules to produce corrugated cardboard, while simultaneously controlling the intermediate conveyor linkage module to transport and store all the corrugated cardboard. Additionally, it also accommodates the storage and transportation of corrugated cardboard produced to meet personalized customization needs.

[0009] To address the pain point of poor process coordination, this invention utilizes an intermediate conveyor linkage module to simultaneously receive corrugated cardboard from the first processing module for small-batch customized production and from the second processing module for large-scale production. This intermediate conveyor linkage module enables integrated production with the packaging processing module, replacing the traditional independent equipment production mode of manual transfer, connection, and scheduling. During order changes, there is no need to stop each process and manually adjust parameters; instead, corrugated cardboard is received from either the first or second processing module as needed, then received and stored via the intermediate conveyor linkage module. The stored corrugated cardboard can then be continuously packaged and packed by the packaging processing module as required, significantly reducing the time spent waiting and adjusting between processes, achieving automated connection between processes, and significantly improving overall production efficiency.

[0010] Meanwhile, in order to break down production data silos, this invention relies on Internet of Things (IoT) technology to achieve interconnection and interoperability of equipment operation data, process parameters, and energy consumption data across the entire production line through an IoT control module. This enables collaborative management and control of the entire production process, replacing the traditional scheduling model that relies on manual experience. It can automatically balance the utilization rate of the first and second processing modules with order changeover costs based on order delivery requirements. This not only solves the problem of low equipment utilization in the traditional production model, but also reduces unnecessary material losses through unified management and control of data throughout the entire process, achieving refined energy consumption management and reducing overall production and operating costs.

[0011] To supplement flexible production capabilities and meet the production needs of orders in multiple scenarios, the IoT control module is compatible with both small-batch customized production and large-scale production processing modules, which can adapt to the production needs of different order sizes. The intermediate conveyor linkage module transports and stores the produced corrugated cardboard, which can buffer the production cycle of corrugated cardboard output in the entire production line. It can quickly adapt to personalized customized orders with different specifications and design requirements, and meet the current market's personalized production requirements for corrugated cardboard.

[0012] Therefore, this invention realizes the integrated operation of the entire corrugated cardboard production line linkage control, intelligent logistics transportation and production data collaborative management, breaking through the technical bottlenecks of low process connection efficiency, high quality control difficulty and insufficient flexible production capacity under the traditional production mode. It truly realizes the operation of corrugated cardboard production with fewer people, higher efficiency and flexibility, meets the high standard requirements of the current packaging market for corrugated cardboard production, and adapts to the development direction of intelligent upgrading in the industry.

[0013] 2) The fully automated cardboard conveying system based on IoT transportation as described in 1), wherein: The first processing module is set as the original processing area in the factory. The processing area is connected to the intermediate conveyor linkage module in the direction of the intermediate conveyor linkage module. The processing area is equipped with an AuPai machine, a digital printing machine and a rotary die-cutting machine in sequence. The corrugated cardboard is processed by the digital printing machine-AuPai machine-rotary die-cutting machine to form corrugated cardboard that meets the production needs of different order sizes. The digital printing machine is used for digital printing of corrugated cardboard, the AuPai machine is used for AuPai crease and slotting of corrugated cardboard, and the rotary die-cutting machine is used for rotary die-cutting. This allows the first processing module to sequentially produce small batches of corrugated cardboard in the processing area of ​​digital printing, AuPai crease and slotting and rotary die-cutting.

[0014] This invention transforms the factory's existing processing area into a primary processing module adapted for small-batch corrugated cardboard production. This fully utilizes existing site and facility resources, avoiding the need for additional production space and reducing the cost of modifying production for small-batch orders. Within the module, digital printing machines, AuPai machines, and rotary die-cutting machines are arranged in the processing sequence of digital printing, AuPai crease and slotting, and rotary die-cutting. The processing flow is sequentially connected to the intermediate conveyor module, ensuring a clear and smooth workflow, eliminating wasted steps and improving the processing efficiency of small-batch corrugated cardboard. The functional division of different equipment precisely matches processing requirements: the digital printing machine completes customized digital printing on the corrugated cardboard, the AuPai machine completes crease and slotting, and the rotary die-cutting machine completes forming and die-cutting. The entire processing flow can flexibly adapt to different order sizes, especially the production needs of small-batch customized corrugated cardboard, supplementing the original production system's adaptability to small-batch orders, enriching the factory's order acceptance range, and balancing the utilization of existing resources with the production adaptability of various order types.

[0015] 3) The fully automated cardboard conveying system based on IoT transportation as described in 2), wherein: The processing area also includes a hand-nail machine and a manual box gluing machine. The manual box gluing machine is used to manually apply glue to bond and fix the overlapping edges of the corrugated cardboard boxes, and the hand-nail machine is used to manually nail and fix the overlapping edges of the corrugated cardboard boxes.

[0016] This invention utilizes the existing processing area of ​​the factory to form the first processing module, which, together with the directional processing flow of digital printing, Aupai crease and slotting, rotary die-cutting, manual gluing machine, and hand-stitching machine, ensures clear and smooth process connections and can accurately adapt to the forming and processing requirements of corrugated boxes. At the same time, it provides two overlapping edge fixing processes, namely gluing and stitching, which can adapt to the production needs of corrugated boxes of different specifications and strength requirements. The whole invention forms a dedicated processing area for small-batch corrugated boxes by combining existing equipment on a small scale.

[0017] 4) The fully automated cardboard conveying system based on IoT transportation as described in 1), wherein: The second processing module is equipped with an array of tracked conveyors spaced apart in the transport direction of the intermediate conveying linkage module. The array of tracked conveyors includes a first set of tracked conveyors, a second set of tracked conveyors, a third set of tracked conveyors, and a fourth set of tracked conveyors. The discharge ports of the first set of tracked conveyors, the second set of tracked conveyors, the third set of tracked conveyors, and the fourth set of tracked conveyors are respectively connected to the lower side of the intermediate conveying linkage module. The inlet of the first set of tracked conveyors is connected to the first printing, slotting, and die-cutting machine. The inlet of the second set of tracked conveyors is connected to the second printing, slotting, and die-cutting machine. The first set of tracked conveyors, the second set of tracked conveyors, the third set of tracked conveyors, and the fourth set of tracked conveyors are connected to the fourth printing, slotting, and die-cutting machine. The corrugated cardboard is directionally conveyed to the intermediate conveying linkage module by the first set of tracked conveyors, the second set of tracked conveyors, the third set of tracked conveyors, and the fourth set of tracked conveyors, either jointly or in a distributed manner.

[0018] The second processing module is equipped with four sets of tracked conveyors at intervals along the transport direction of the intermediate conveyor linkage module: the first set, the second set, the third set, and the fourth set. Each set of tracked conveyors is connected to an independent printing, slotting, and die-cutting machine. The discharge ports of each set of tracked conveyors face downwards towards the intermediate conveyor linkage module. This allows multiple printing, slotting, and die-cutting machines to simultaneously transport corrugated cardboard to the intermediate conveyor linkage module. Alternatively, depending on production needs, only some printing, slotting, and die-cutting machines can be activated for distributed directional material conveying. This adapts to the processing and production needs of corrugated cardboard of different scales and types, improving the flexibility of equipment production scheduling. At the same time, the overall processing capacity can be expanded through parallel operation of multiple machines, ensuring the stability of directional material conveying of corrugated cardboard and avoiding interference between the material conveying of different equipment.

[0019] 5) The fully automated cardboard conveying system based on IoT transportation as described in 4), wherein: The first, second, third, and fourth printing and slotting die-cutting machines are identical devices. They are all connected to the IoT control module, which activates them intermittently or in a distributed manner. These machines collectively produce a large quantity of corrugated cardboard.

[0020] By using an IoT control module, four identical printing, slotting, and die-cutting machines can be started in an intermittent or distributed manner. The machines can work together to stably handle the production of large quantities of corrugated cardboard. This allows for flexible scheduling of production cycles based on capacity requirements, avoiding the impact on the power grid load caused by multiple machines starting simultaneously. It also enables the release of capacity through the collaboration of multiple machines, meeting the efficiency requirements of large-scale corrugated cardboard production and ensuring the delivery capability of large orders.

[0021] 6) The fully automated cardboard conveying system based on IoT transportation as described in 5), wherein: The second printing, slotting, and die-cutting machine includes a die-cutting unit, a slotting unit, a first printing unit, a second printing unit, a third printing unit, a paper feeding unit, and a belt conveyor. The paper feeding unit separates and aligns stacked corrugated cardboard sheets, conveying them towards the first printing unit. The first printing unit prints a base color or main color on the surface of the corrugated cardboard. The second printing unit prints multiple colors or patterns on the surface of the corrugated cardboard. The third printing unit prints text or applies varnish to the surface of the corrugated cardboard. The slotting unit presses creases, slots, or trims edges on the corrugated cardboard to form the shape of a corrugated box. The die-cutting unit cuts the corrugated cardboard into specific shapes using a specific mold. The belt conveyor connects the paper feeding unit, the first printing unit, the second printing unit, the third printing unit, the slotting unit, and the die-cutting unit, allowing the corrugated cardboard to be transported in a processing direction of paper feeding-printing-slotting-die-cutting-conveyor output.

[0022] In this invention, the first, second, third, and fourth printing and slotting die-cutting machines are identical equipment. Therefore, these machines can simultaneously achieve integrated operation of the entire corrugated carton production process. Through the cooperation of each functional unit and the belt conveyor, a continuous processing link is formed, consisting of paper feeding, printing, slotting, die-cutting, and unloading. The specific technical effects are as follows: The paper feeding process is precise and orderly: the paper feeding unit can automatically separate and align stacked corrugated cardboard sheets, accurately conveying the cardboard to the subsequent processing units. This avoids paper jams and cardboard misalignment from the start of processing, laying the foundation for subsequent high-precision processing, reducing the workload of manual material handling, and improving the stability of the paper feeding process.

[0023] The printing process covers diverse needs: Through three clearly defined printing units, base / main color printing, color printing / pattern printing, text printing, or varnishing can be completed sequentially. This can meet the layered printing processing needs of different graphics and texts on corrugated boxes. It is not only suitable for the multi-color printing requirements of ordinary graphic boxes, but also can complete the post-processing of varnishing and protective film. The process compatibility is strong, and the layered printing processing logic also ensures the accuracy of color printing and improves the quality of the final printed product.

[0024] The forming and processing meet the requirements of carton production: the grooving unit can complete the corrugated cardboard folding, grooving and corner cutting processes in one go, directly processing the basic shape of the corrugated cardboard box without multiple transfers for forming; the die-cutting unit can complete the cutting of irregular shapes with specific molds, which is suitable for the production of standard corrugated cardboard boxes and can also meet the processing needs of customized irregular corrugated cardboard boxes, thus expanding the processing range of the equipment.

[0025] Achieving continuous and automated processing: The belt conveyor connects the functional units in an orderly manner along the processing direction, ensuring that corrugated cardboard is continuously transported and processed according to the production process. It integrates the scattered single-process processing into an integrated production line, reduces the waiting time between processes, reduces the cost and error of manual transfer, and improves the overall efficiency and automation level of corrugated box production and processing.

[0026] 7) The fully automated cardboard conveying system based on IoT transportation as described in 1), wherein: The intermediate conveying linkage module includes a first set of tracks and a second set of tracks arranged side by side and spaced apart. The two ends of the first set of tracks and the two ends of the second set of tracks are respectively connected to the first processing module and the packaging processing module. Several first linkage track conveyors are arranged side by side between the first set of tracks and the second set of tracks. The inlet and outlet of each first linkage track conveyor correspond to the first set of tracks and the second set of tracks, respectively. Several shuttle cars for carrying corrugated cardboard are slidably connected on the first set of tracks and the second set of tracks. Each shuttle car can selectively transport corrugated cardboard from the first processing module to the packaging processing module, from the first set of tracks to a designated first linkage track conveyor for storage, or from the first linkage track conveyor containing corrugated cardboard to the packaging processing module.

[0027] The intermediate conveying linkage module of this invention, through its dual-track design with a linked crawler conveyor and a carrying shuttle, enables three differentiated corrugated cardboard conveying and scheduling functions: it supports the shuttle directly transporting corrugated cardboard from the front-end first processing module to the rear-end packaging processing module, meeting the needs of continuous and smooth routine production conveying; it can also transfer corrugated cardboard to be processed from the first set of tracks to the corresponding first linked crawler conveyor for temporary storage, realizing production buffering and peak-shifting adjustment of production rhythm; and it can also transfer corrugated cardboard temporarily stored on the first linked crawler conveyor to the packaging processing module to complete replenishment production. Overall, it realizes flexible scheduling of corrugated cardboard between processing and packaging processes, adapting to different production capacity rhythms and different order production needs, and improving the conveying flexibility and production responsiveness of the corrugated cardboard processing and packaging production line.

[0028] 8) The fully automated cardboard conveying system based on IoT transportation as described in 7), wherein: The second set of tracks is connected to the second processing module below. A second linked crawler conveyor is provided below the second set of tracks and on one side of the second processing module. The shuttle on the second set of tracks can selectively transport corrugated cardboard from the second processing module to the packaging processing module, from the second set of tracks to a designated second linked crawler conveyor for storage, or from the second linked crawler conveyor storing corrugated cardboard to the packaging processing module.

[0029] This invention enables flexible scheduling of corrugated cardboard transportation routes, and can complete three different transfer operations according to actual production needs: transporting corrugated cardboard directly from the second processing module to the packaging processing module, transferring corrugated cardboard from the second set of tracks to the second linked crawler conveyor for temporary storage, or transferring the stored corrugated cardboard from the second linked crawler conveyor to the packaging processing module, which can adapt to the production scheduling needs of different production rhythms and different capacity fluctuations.

[0030] By adding a second linked crawler conveyor as a temporary buffer node, the production cycle difference between the second processing module and the packaging processing module is balanced. When one module experiences capacity fluctuations or temporary shutdowns, production continuity can be ensured by temporarily storing corrugated cardboard or retrieving pre-stored corrugated cardboard, avoiding production line downtime due to material shortages and improving overall production stability. Furthermore, the placement of the second linked crawler conveyor is compatible with the shuttle car's scheduling logic on the second set of tracks, with a reasonable connection position that does not interfere with the normal processing and output of the second processing module. It also ensures smooth shuttle car transfer operations without requiring additional transfer structures, simplifying the production line layout and reducing the complexity of scheduling and control.

[0031] 9) The fully automated cardboard conveying system based on IoT transportation as described in 1), wherein: The packaging processing module includes a first set of spare tracked conveyors, a second set of spare tracked conveyors, and a packing machine for wrapping and packing corrugated cardboard, which are spaced apart and arranged side by side along the transport direction of the intermediate conveyor linkage module. The feed inlets of the first set of spare tracked conveyors and the second set of spare tracked conveyors are close to the first set of tracks in the intermediate conveyor linkage module. The shuttle cars in the first set of tracks can selectively transport corrugated cardboard to the first set of spare tracked conveyors for storage, or to the second set of spare tracked conveyors for storage, or to the packing machine for wrapping and packing.

[0032] This invention enables flexible diversion, buffering, and packaging operation scheduling for corrugated cardboard. By setting up two sets of alternately spaced, parallel backup conveyor belts as buffer stations, the system allows for flexible diversion and storage of corrugated cardboard to be processed to the two backup buffer stations when the packaging machine is operating at full capacity, undergoing maintenance, or when packaging is not currently required. This prevents the entire corrugated cardboard production line from stopping due to congestion in the packaging process, effectively offsetting the impact of front-end production fluctuations and back-end packaging failures on the overall production capacity, and improving the continuous operation capability and anti-interference capability of the entire production line. Simultaneously, the shuttle can selectively complete three operation path scheduling according to actual production needs: directly feeding corrugated cardboard into the packaging machine, feeding it into the first set of backup conveyor belts for buffering, or feeding it into the second set of backup conveyor belts for buffering. This adapts to various production scenarios such as "produce and package immediately," "batch buffering and centralized packaging," and "categorized buffering of different specifications of corrugated cardboard," meeting the mixed-line production scheduling needs of multiple orders and multiple specifications of corrugated cardboard, and improving the adaptability of the packaging and processing process.

[0033] Meanwhile, this invention features a compact hardware layout and high space utilization. The first and second sets of backup tracked conveyors are arranged side-by-side at intervals along the conveying direction, with the feed inlets uniformly located near the first track of the central conveying linkage module. No additional site expansion or modification of the conveying path is required; scheduling can be completed using the existing track shuttle. This expands the buffering function while ensuring a compact overall production line layout and reducing factory space occupation. Simultaneously, it reduces equipment idle rate and improves the input-output ratio. The first and second backup tracked conveyors serve as both temporary buffers and can be expanded into pre-processing stations according to capacity requirements. The dual-buffer configuration also allows for maintenance and repair of one device, preventing loss of buffering function due to a single buffer device failure. This ensures the overall availability of equipment in the packaging and processing stage, avoiding the problem of a single buffer device failure affecting the entire line operation, thus improving the utilization efficiency of equipment resources.

[0034] 10) The fully automated cardboard conveying system based on Internet of Things transportation as described in 1), wherein: The IoT control module includes an intelligent control unit and a data collaborative management unit. The intelligent control unit uses a PLC program to control the operation of the first set of tracked conveyors, the second set of tracked conveyors, the third set of tracked conveyors, the fourth set of tracked conveyors, the first linked tracked conveyor, the second linked tracked conveyor, the first set of spare tracked conveyors, the second set of spare tracked conveyors, and the shuttle. The data collaborative management unit receives orders for corrugated cardboard produced in small batches by the first processing module and orders for corrugated cardboard produced in large batches by the second processing module. It also performs data statistics, data interaction, and instruction transmission on the quantity of corrugated cardboard transported and stored by the intermediate transport linkage module.

[0035] This invention relies on PLC program control of an intelligent control unit to achieve unified programmable management and control of the operation of nine different types of transportation execution equipment, including the first to fourth groups of tracked conveyors, two groups of linked tracked conveyors, two groups of spare tracked conveyors, and shuttle cars. This ensures both the accuracy of individual equipment actions and supports the coordinated matching of multiple equipment actions, providing a stable and reliable automated control foundation for the transfer and buffering processes of corrugated cardboard at different production scales. It avoids the problems of action errors and scheduling chaos caused by manual operation, improving the reliability of the transportation process. Simultaneously, through the data collaboration management unit, it can receive small-batch corrugated cardboard orders from the first processing module. The second processing module provides demand information for large-volume corrugated cardboard orders. It can dynamically collect data on the real-time transportation status and storage quantity of corrugated cardboard in the intermediate transportation linkage module for different production modes. It opens up the data path between front-end production ordering, intermediate transfer buffering, and back-end processing, and can synchronously complete cross-module data interaction and instruction transmission. It solves the problems of data incompatibility and scheduling lag in the transportation link under different batch production scenarios. It can adapt to the continuous transportation needs of large-volume orders and also meet the flexible scheduling and adjustment of small-volume orders, improving the adaptability of the entire corrugated cardboard production line to multiple order types and the overall operating efficiency.

[0036] 11) A fully automated cardboard conveying method based on Internet of Things (IoT) transportation, applied to the fully automated cardboard conveying system based on IoT transportation described in 1)-10) above, includes the following steps: Step 1: For different corrugated cardboard production order requirements, the IoT control module transmits instructions to the first processing module, the second processing module, the intermediate conveyor linkage module, and the packaging processing module. The first processing module and / or the second processing module are selectively activated, so that the first processing module produces corrugated cardboard in small batches according to the order requirements, and the second processing module produces corrugated cardboard in large batches according to the order requirements. The data from the first processing module and the second processing module is fed back to the IoT control module. Step 2: While the first processing module and / or the second processing module are continuously producing corrugated cardboard, the shuttle car in the intermediate conveyor linkage module receives the corrugated cardboard produced by the first processing module and / or the second processing module. According to the order requirements, the Internet of Things control module controls the start of each crawler conveyor at different positions in the intermediate conveyor linkage module to receive and / or transport the corrugated cardboard. When each crawler conveyor receives the corrugated cardboard from the shuttle car, all the corrugated cardboard can be stored on the crawler conveyor. When each crawler conveyor transports the corrugated cardboard to the shuttle car, the corrugated cardboard can be transported towards the first processing module and processed according to the corrugated carton production requirements, or the corrugated cardboard can be transported towards the packaging processing module and wrapped and packaged. Step 3: When corrugated cardboard is received in the packaging processing module, each spare conveyor belt can selectively receive the corrugated cardboard and store it, or a packing machine can be installed at the corresponding position of the spare conveyor belt to wrap and pack the corrugated cardboard in real time.

[0037] Compared with the prior art, the present invention also has the following technical effects: 1. Flexible adaptation to corrugated cardboard production orders of different sizes: Relying on the Internet of Things control module to realize unified command issuance and production data feedback, the first processing module or the second processing module can be flexibly and selectively activated according to the order batch size. It supports flexible production of small batch customized orders and can also meet the efficient processing of large batch large-scale orders. It solves the problem that traditional production lines cannot simultaneously take into account flexible small batch production and stable large batch processing, and improves the production line's adaptability to different order requirements.

[0038] 2. Achieve dynamic and interconnected conveying in the corrugated cardboard production process: Based on the Internet of Things control module, the start and stop of the conveyor belts at different positions in the intermediate conveying linkage module can be dynamically adjusted according to the order flow demand. In conjunction with the shuttle car, the corrugated cardboard is transferred between different production stages. It can temporarily buffer the produced corrugated cardboard to balance the production line capacity, and can also flexibly adjust the conveying direction according to the subsequent processing needs: the corrugated cardboard is transported in reverse to the corrugated carton processing stage for further processing, or transported in the forward direction to the packaging stage to complete the shipment and packaging. This realizes intelligent and dynamic scheduling of the production conveying process, eliminates the inflexibility defects of traditional fixed conveying routes, and improves the overall production flow efficiency.

[0039] 3. Enhance production flexibility in the packaging process: By using a standby conveyor belt that can be selectively activated in conjunction with modularly installed packing machines, the standby conveyor belt can temporarily buffer incoming corrugated cardboard, preventing congestion and production stoppages at the packaging station after the previous production is completed. Alternatively, packing machines can be quickly configured at the corresponding locations according to packing needs, enabling real-time synchronous packing of corrugated cardboard. This balances the needs of buffering and pressure adjustment with immediate packing, improving the overall line's buffering capacity and packing efficiency to cope with different production rhythms, avoiding production line congestion and material shortages, and ensuring the continuity of overall production.

[0042] See the example. Figure 1 As shown, the fully automated cardboard conveying system based on IoT transportation in this embodiment includes a first processing module 1, a second processing module 2, an intermediate conveying linkage module 3, and a packaging processing module 4, as well as an IoT control module that is connected to the first processing module 1, the second processing module 2, the intermediate conveying linkage module 3, and the packaging processing module 4 via a wireless network. The first processing module 1 is configured as a processing area for small-batch production of corrugated cardboard, in which corrugated cardboard is sequentially processed by digital printing, Aupai grooving, and rotary die-cutting to obtain corrugated cardboard.

[0043] More specifically, the first processing module 1 is set as the existing processing area within the factory, and the processing area is connected to the intermediate conveyor linkage module 3 in the direction facing the intermediate conveyor linkage module 3. Figure 2 As shown, in this embodiment, an Orp-type printing machine 102, a digital printing machine 103, and a rotary die-cutting machine 105 are sequentially arranged in the processing area. Corrugated cardboard is processed in the direction of digital printing machine 103-Orp-type printing machine 102-rotary die-cutting machine 105 to form corrugated cardboard that meets the production needs of different order sizes. Among them, the digital printing machine 103 is used for digital printing of corrugated cardboard and is controlled by the Internet of Things control module, the Orp-type printing machine 102 is used for Orp-type crease and slotting of corrugated cardboard and is controlled by the Internet of Things control module, and the rotary die-cutting machine 105 is used for rotary die-cutting and is controlled by the Internet of Things control module. This allows the first processing module 1 to sequentially process the digital printing, Orp-type crease and slotting, and rotary die-cutting areas to generate small batches of corrugated cardboard.

The first processing module 1 and / or the second processing module 2 are selectively activated, so that the first processing module 1 produces corrugated cardboard in small batches according to the order requirements, and the second processing module 2 produces corrugated cardboard in large batches according to the order requirements. The first processing module 1 and the second processing module 2 feed back data to the IoT control module. Step 2: When the first processing module 1 and / or the second processing module 2 are continuously producing corrugated cardboard, the shuttle 302 in the intermediate conveyor linkage module 3 receives the corrugated cardboard produced by the first processing module 1 and / or the second processing module 2. According to the order requirements, the Internet of Things control module controls the start of each tracked conveyor at different positions in the intermediate conveyor linkage module 3. Each tracked conveyor receives and / or transports the corrugated cardboard. When each tracked conveyor receives the corrugated cardboard on the shuttle 302, all the corrugated cardboard can be stored on the tracked conveyor. When each tracked conveyor transports the corrugated cardboard to the shuttle 302, the corrugated cardboard can be transported towards the first processing module 1 and processed according to the corrugated carton production requirements, or the corrugated cardboard can be transported towards the packaging processing module 4 and wrapped and packaged. Step 3: When corrugated cardboard is received in the packaging processing module 4, each spare conveyor can selectively receive the corrugated cardboard and store it, or a packing machine 403 can be installed at the corresponding position of the spare conveyor to wrap and pack the corrugated cardboard in real time.
