Description

Technical Field

[0001] The present invention relates to the technical field of tobacco processing equipment, and in particular to an intelligent dynamic scheduling device and system applied to a universal sorting line. Background Art

[0002] As the industry promotes high-quality development of tobacco leaves in all aspects, the requirements for tobacco raw materials are getting higher and higher, and the concept of tobacco production is also being updated towards "equal emphasis on quality and efficiency". The industry is continuously increasing its investment in automation and intelligent production processes. However, the current domestic tobacco sorting work is still mainly in the stage of assembly line manual sorting and pure manual sorting, and there are few automated mechanical equipment in the sorting process. During the sorting process, auxiliary work in the sorting process, such as transporting burlap bags to the sorting table and sending the selected tobacco leaves to the quality inspection table, is still mainly completed manually. During the sorting process of the Shilin Redrying Plant in the 2024 baking season, there were a total of 510 people in the sorting process, of which only 360 were sorting workers, and the remaining 150 were responsible for auxiliary sorting work such as burlap bag loading, quality inspection, and cleaning. The efficiency of manual use is not high. At this stage, a small number of redrying plants have also introduced ring sorting lines for the transportation of tobacco bales and selected tobacco leaves, but they all have the following problems:

[0003] (1) Most of the existing ring sorting line equipment is a fixed conveyor line, which only plays the function of material transportation. It is unable to dynamically adjust the material distribution according to the load of the sorting table and quality inspection table, and fails to realize the intelligent distribution of materials, which easily causes local congestion or idleness.

[0004] (2) The existing circular sorting line is difficult to form an information closed loop for tobacco leaf sorting and can only realize basic transportation functions. At the same time, the existing circular sorting line often only supports sorting tobacco leaves below 5 grades. However, for redrying plants with import and export tobacco leaf processing requirements, more than 10 grades need to be sorted at one time, and the existing circular sorting line cannot meet the requirements.

[0005] (3) The existing ring sorting line still requires a lot of manpower to complete auxiliary work, and the labor utilization rate is not high.

[0006] Therefore, in view of the shortcomings of the above-mentioned existing ring sorting lines, it is urgent to propose a sorting line that can realize intelligent dynamic scheduling and meet multi-level sorting. Summary of the Invention

[0007] The purpose of the present invention is to provide an intelligent dynamic scheduling device and system for a universal sorting line to solve technical problems existing in the traditional tobacco sorting process, such as high manual dependence, rigid material scheduling, lack of information traceability, and lack of support for intelligent quality inspection scheduling.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solutions: an intelligent dynamic scheduling device applied to a universal sorting line, comprising a sack transfer line, a full frame transfer line, an empty frame transfer line, a universal sorting table, a post-selection quality inspection table, and a post-selection framing area;

[0009] The jute bag transfer line is used for the transfer of jute bags. During the transfer process, the jute bag information is read and transmitted to the electronic control system. The electronic control system tracks the conveyor line. When the jute bags arrive at the designated leaf selection station, the tobacco pushing mechanism pushes them to the round jute bag table.

[0010] The solid frame transfer line is used to load the tobacco frames of selected tobacco leaves and transfer them to the conveyor line of the quality inspection station. The solid frame transfer line collects the solid frames of multiple leaf selection units and transfers them to the quality inspection station;

[0011] The empty frame transfer line is used to transport the empty cigarette frames after the selected cigarette frame information is erased to each sorting group; the solid frame transfer line and the empty frame transfer line are divided into two layers, and the solid frame transfer line and the empty frame transfer line are arranged between two rows of sorting tables, the upper layer is the empty frame transfer line, and the lower layer is the solid frame transfer line;

[0012] The universal sorting table consists of 6 small sorting tables, a temporary storage table for sacks, a manual ladder, and a tobacco rack loading table. The 6 small sorting tables are used to accommodate 12 tobacco sorting personnel for work; the temporary storage table for sacks is used for temporary storage of sacks; the manual ladder is used for personnel to enter and exit the tobacco sorting unit; the tobacco rack loading table is in a ring shape and is used to place tobacco racks of more than 20 grades.

[0013] The post-selection quality inspection station is used to perform quality inspection on the post-selection tobacco leaves;

[0014] The post-selection framing area is used for framing according to tobacco leaf grades.

[0015] Preferably, a facade design is performed between the conveyor lines, and the conveyor lines are divided into three layers, namely the first layer, the second layer and the burlap layer. The first layer is the temporary storage line for the post-selection cigarette frames, with a floor height of 180mm; the second layer is a manual working platform with a height of 760mm; the burlap layer has a height of 1900mm, which is used to optimize the working space of the leaf selectors, and some transfer lines pass under the inclined rods.

[0016] Preferably, the jute bag transfer line is provided with an intelligent interface for the jute bags on the robot arm, and the raw tobacco frames are allocated to the leaf selection line and the jute bag loading port according to the origin, grade and batch.

[0017] Preferably, an intelligent quality inspection equipment interface is reserved at the post-selection quality inspection station for access to subsequent intelligent quality inspection equipment, and a manipulator access port is reserved behind the post-selection quality inspection station for access to the manipulator.

[0018] Preferably, the specifications of the 6 small sorting tables are: length 1800mm, width 1600mm, height 700; the radius of the sack temporary storage table is 1750mm, which is used to connect the sack conveyor line; the cigarette frame loading table is 180mm high and 1600mm wide, and the outside of the cigarette frame loading table is the empty cigarette frame conveyor line.

[0019] Preferably, the solid frame transfer line in the leaf selection area is at the same level as the solid frame transfer line, and after the empty frame line reaches the leaf selection unit, it slopes down to the same level as the solid frame transfer line.

[0020] An intelligent dynamic scheduling system for a universal sorting line, comprising any of the above-mentioned intelligent dynamic scheduling devices for a universal sorting line, including a cigarette rack information binding station, a sack conveyor line tracking system, a cigarette rack full rack detection system, a cigarette rack transfer tracking system, and a quality inspection station dynamic allocation system;

[0021] The tobacco frame information binding station is set on the actual frame transfer line, and the grade information, leaf selection group information and origin information of the tobacco frame are automatically bound to the information carrier of the tobacco frame through the conveyor line tracking technology;

[0022] The sack conveyor line tracking system manually scans and reads the sack electronic tag information at the loading port and transmits it to the electronic control system, which tracks the sack conveyor line. When the sack arrives at the designated leaf selection station, it is pushed out by the tobacco pushing mechanism and slides to the circular sack table.

[0023] The full-frame detection system consists of three groups of photoelectric devices, which are used to detect in real time whether tobacco leaves are exceeding the front, middle and rear ends of the frame. When obstruction is detected at the same time, the frame is considered full. When the frame is full, the frame is ejected from the selection unit to the full-frame transfer line.

[0024] The tobacco frame transfer tracking system automatically binds the grade information, leaf selection group information and origin information of the tobacco leaves to the information carrier of the tobacco frame. After the selected tobacco leaves have completed the re-inspection, the tobacco frame information is erased and the leaves enter the empty frame transfer line.

[0025] The dynamic allocation system for quality inspection stations initializes the grouping of re-inspection stations based on historical batch data using historical percentage data, and splits the maximum level into multiple re-inspection stations for balancing. If the number of levels is greater than the number of re-inspection stations, a high-low ratio match is first performed, and then a larger level is selected for dynamic balancing to balance the flow of cigarette frames at each re-inspection station. At the same time, statistics are collected on the levels of cigarette frames and the number of each level on the selected cigarette frame transfer line, and real-time allocation of re-inspection station levels is performed based on this real-time data.

[0026] Preferably, the universal sorting line is divided into 24 areas, and the areas are graded by the management system. The sorting line is controlled by a servo motor, and the position of tobacco leaves in each area is recorded and tracked by an encoder and an electronic control system. At the same time, an identification plate is set in each area for manual identification of the area grade.

[0027] Preferably, the jute bag transfer line passes through each sorting table, and the information system allocates the sorting line and the loading port according to the origin, grade and batch of the original tobacco. The electronic tag of the cigarette frame is manually scanned at the loading port to verify the information, and the jute bag is manually placed on the conveyor line. During the transfer process, the jute bag information is read and transmitted to the electronic control system, which tracks the jute bag on the conveyor line through the electronic control system. When the jute bag arrives at the designated leaf selection table, it is pushed out by the tobacco pushing mechanism and slides to the circular jute bag table.

[0028] Preferably, the solid frame transfer line collects the solid frames of multiple leaf selection units and transfers them to the quality inspection station. The climbing and descending processing are set according to the flow. A dynamic allocation system for the quality inspection station is provided from the solid frame transfer line to the quality inspection station, which intelligently allocates the selected cigarette frames by identifying the flow of the quality inspection station.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The present invention reduces the use of manpower in the sorting process, adopts dynamic logistics scheduling, and realizes dynamic regulation and flexible processing of materials through the intermediate logistics links according to the real-time flow of leaf-selecting unit burlap bags, empty cigarette frames, small cigarette frames of different grades, and small cigarette frames of different grades at the quality inspection table, thereby avoiding the accumulation and congestion of materials and achieving dynamic balance of logistics within the system.

[0031] 2. This invention utilizes a universal sorting table to address the limited number of sorting grades supported after sorting. It can efficiently sort up to 24 grades simultaneously, using a universal conveyor line to deliver "frame-to-person" operation, eliminating manual back-and-forth movement. Furthermore, cigarette frames can be combined based on the amount of sorting required, with multiple frames for large-volume grades and one to two frames for small-volume grades. Dynamic adjustments based on batch size improve system flexibility and adaptability, meeting the processing needs of industrial enterprises for refined, modular, and homogenized raw cigarettes.

[0032] 3. The present invention can record sorting, quality inspection and packing data in real time, adopt a variety of intelligent recognition technologies, and collect data in real time to ensure the correct reading and writing of information in each link, each process and each material. Through the upper-level material management system, it improves the granularity of management, enhances the manager's macro-control and dynamic adjustment of the leaf selection link, and realizes digital governance.

[0035] Figure 3 This is a flow chart of the universal sorting line of the present invention. DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] See also Figure 1-3 , the present invention provides a technical solution: an intelligent dynamic scheduling device applied to a universal sorting line, comprising a sack transfer line, a full frame transfer line, an empty frame transfer line, a universal sorting table, a post-selection quality inspection table and a post-selection framing area;

[0038] The jute bag transfer line is used for the transfer of jute bags. During the transfer process, the jute bag information is read and transmitted to the electronic control system. The electronic control system tracks the conveyor line. When the bag arrives at the designated leaf selection station, it is pushed to the round jute bag table by the tobacco pushing mechanism.

[0039] It should be noted that an electronic tag scanning device is installed at the loading port for sacks. When a sack is manually placed at the loading port, the scanning device automatically reads the electronic tag information on the sack and transmits the information to the electronic control system. The electronic control system accurately allocates the sacks to the corresponding sorting lines and loading ports based on information such as the origin, grade, and batch of the raw tobacco. During the transportation process, the electronic control system tracks the sack's position in real time through sensors installed on the conveyor line. When the sack reaches the designated leaf selection table, the electronic control system controls the tobacco pushing mechanism to push the sack off the conveyor line and slide it to the circular sack table for easy access by the leaf selectors.

[0040] The solid frame transfer line is used to load the tobacco frames of selected tobacco leaves and transfer them to the conveyor line of the quality inspection station. The solid frame transfer line collects the solid frames of multiple leaf selection units and transfers them to the quality inspection station.

[0041] It should be noted that the solid frame transfer line can be set with climbing and descending processing according to the smoke flow rate of the transfer. During the transfer process, the smooth operation of the conveyor line ensures that the smoke frames arrive at the quality inspection station safely and accurately. A dynamic allocation system for the quality inspection station is provided from the solid frame transfer line to the quality inspection station. By identifying the flow rate of the quality inspection station and intelligently allocating the selected smoke frames, it can reduce the flow congestion or idle rate to the quality inspection station; the dynamic allocation system for the quality inspection station initializes the grouping of the re-inspection stations based on the historical percentage data of the batch history data, and splits the maximum level into multiple re-inspection stations for balancing; if the number of levels is greater than the number of re-inspection stations, the high and low ratios are matched first, and then a larger level is selected for dynamic balancing, so as to balance the smoke frame flow of each re-inspection station and reduce the possibility of congestion.

[0042] The empty frame transfer line is used to transport the empty cigarette frames after the selected cigarette frame information is erased to each sorting group; the solid frame transfer line and the empty frame transfer line are divided into two layers, and the solid frame transfer line and the empty frame transfer line are respectively arranged between the two rows of sorting tables, the upper layer is the empty frame transfer line, and the lower layer is the solid frame transfer line.

[0043] It should be noted that the solid frame transfer line and the empty frame transfer line are divided into two layers, and are set between two rows of sorting tables; the upper layer is the empty frame transfer line, and the lower layer is the solid frame transfer line; this layered design effectively utilizes space and avoids line crossing and interference; the empty frame transfer line is responsible for transporting the empty cigarette frames after the selected cigarette frame information is erased to each sorting group. After the empty frame arrives at the leaf selection unit, it is lowered to the same level as the solid frame transfer line through the slope reduction device, which is convenient for the leaf selection personnel to take the empty frame for the next round of tobacco leaf framing.

[0044] The universal sorting table consists of 6 small sorting tables, a burlap temporary storage table, a manual step ladder and a cigarette frame loading table; the specifications of the 6 small sorting tables are: length 1800mm, width 1600mm, height 700mm; the radius of the burlap temporary storage table is 1750mm, which is used to connect the burlap conveyor line; the cigarette frame loading table is 180mm high and 1600mm wide, and the outside of the cigarette frame loading table is the empty cigarette frame conveyor line.

[0045] It should be noted that a universal sorting table is a group, which consists of 6 small sorting tables, a sack temporary storage table, a manual ladder, and a tobacco frame loading table. Each part cooperates with each other to provide an efficient and convenient working environment for the leaf selectors. The specifications of the 6 small sorting tables are: length 1800mm, width 1600mm, height 700mm. The size and height are reasonably designed to meet the needs of two people for the whole selection operation at the same time. The leaf selectors carefully sort the tobacco leaves taken out of the sacks on the small sorting table; the tobacco frame loading table is in a circular shape, outside the small sorting table, The frame loading table is 180mm high and 1600mm wide. It can rotate and accommodate more than 20 grades of frames. Tobacco leaves of different grades produced by each leaf selection table can be placed into plastic frames of corresponding grades without personnel moving around. The empty frame conveyor line is located outside the frame loading table, facilitating the timely replenishment of empty frames. A manual ladder is set 500-600mm between the leaf selection table and the universal sorting line. Leaf selectors use this ladder to uniformly enter and exit the leaf selection unit, ensuring the orderly and safe flow of personnel.

[0046] The post-selection quality inspection table is used to conduct quality inspection on the tobacco leaves after selection.

[0047] It should be noted that the post-selection quality inspection station is equipped with professional quality inspection equipment and personnel. After the sorted tobacco leaves are transferred to the quality inspection station, the quality inspectors conduct a comprehensive inspection of the tobacco leaves according to strict quality standards to ensure that the quality of the tobacco leaves meets the requirements.

[0048] The post-selection framing area is used to frame the tobacco leaves according to their grade.

[0049] It should be noted that the post-selection framing area classifies and frames the tobacco leaves according to their grade. According to the pre-set framing rules, the tobacco leaves that have passed the quality inspection are placed in the corresponding frames to prepare for subsequent storage and transportation.

[0050] In the device, each conveyor line is designed with a facade, which is divided into 3 layers, namely 1st layer, 2nd layer and burlap layer. Among them, 1st layer is the temporary storage line for selected tobacco frames, with a layer height of 180mm, which is used to temporarily store selected tobacco frames; 2nd layer is the manual working platform, with a height of 760mm, which provides a comfortable working height for leaf selectors; the height of the burlap layer is 1900mm, which optimizes the working space of leaf selectors and makes it convenient for them to take burlap bags; in the design process of the conveyor line, full consideration is given to the coordination with the civil engineering structure. Some transfer lines need to pass under the inclined rods. Through precise measurement and design, it is ensured that the conveyor line does not conflict with the civil engineering structure, ensuring the stable operation of the entire system;

[0051] The lower surface height of the original tobacco and tobacco bale transfer line is 1800mm, which allows personnel to work underneath. The tobacco bales slide down to the jute bale temporary storage disc through a slope-down unpowered conveyor. The tail end of the slope-down conveyor is offset to one side at a certain angle to ensure that the jute bales do not roll during the sliding process and can fall accurately on the edge of the round table, making it convenient for leaf selectors to pick them up; the solid frame transfer line in the leaf selection area is at the same level as the leaf selection unit, ensuring that the tobacco frames loaded with selected tobacco leaves can smoothly enter the leaf selection unit for subsequent processing; after the empty frame line reaches the leaf selection unit, it is lowered to the same level as the solid frame transfer line through the slope-down device, realizing smooth handover between empty frames and solid frames.

[0052] An intelligent dynamic scheduling system applied to a universal sorting line includes any of the above intelligent dynamic scheduling devices applied to a universal sorting line, including a cigarette frame information binding station, a sack conveyor line tracking system, a cigarette frame full frame detection, a cigarette frame transfer tracking system and a quality inspection station dynamic allocation system.

[0053] It should be noted that the universal sorting line is divided into 24 areas, and the areas are graded through the management system. The sorting line is controlled by a servo motor, and the position of tobacco leaves in each area is recorded and tracked by encoders and electronic control systems. At the same time, identification signs are set in each area for manual identification of area grades, thereby realizing information alignment of manual-sorting line area-tobacco frame-management system; the burlap bag transfer line passes through each sorting table, and the information system allocates sorting lines and loading ports according to the origin, grade and batch of the original tobacco; the universal sorting table is set up to meet the requirement of sorting tobacco leaves into up to 24 grades, which can meet the sorting needs of domestic and foreign industrial customers.

[0054] The tobacco frame information binding station is set up on the real frame transfer line. Through the conveyor line tracking technology, the grade information, leaf selection group information and origin information of the tobacco frame are automatically bound to the information carrier of the tobacco frame.

[0055] It should be noted that the cigarette frame information binding station is set up on the solid frame transfer line, and the automatic binding of cigarette frame information is realized through specific hardware equipment and software systems. When the cigarette frame is running on the solid frame transfer line, the conveyor line tracking technology obtains the position information of the cigarette frame in real time. According to preset rules, the system automatically binds the cigarette frame's grade information, leaf selection group information, origin and other basic information to the cigarette frame's information carrier (such as electronic tag or QR code). This information will accompany the cigarette frame throughout the entire sorting process to facilitate subsequent tracking and management.

[0056] The jute bag conveyor line tracking system manually scans and reads the electronic tag information of the jute bag at the feeding port and transmits it to the electronic control system. The electronic control system tracks the jute bag on the conveyor line. When the jute bag reaches the designated leaf selection station, it is pushed out by the tobacco pushing mechanism and slides to the round jute bag table.

[0057] It should be noted that at the loading port, after the electronic tag information of the sack is manually scanned and read, the information is quickly transmitted to the electronic control system via wired or wireless means. The electronic control system parses and processes the received information to establish a sack information database; the electronic control system tracks the conveying status of the sack in real time based on the data in the sack information database and the position information fed back by the sensors installed on the conveyor line, and ensures that the sack can accurately reach the designated leaf selection station by precisely controlling the running speed of the conveyor line and the action time of the tobacco pushing mechanism.

[0058] The full-frame detection system consists of three sets of photoelectric equipment, which are used to detect in real time the excess of tobacco leaves at the front, middle and tail ends of the frame. When obstruction is detected at the same time, the frame is deemed to be full. When it is detected that the frame is full, the frame is removed from the leaf selection unit to the full-frame transfer line by the frame throwing station.

[0059] It should be noted that three sets of photoelectric equipment are installed above the tobacco frame of the leaf selection unit, corresponding to the front end, middle part and tail end of the tobacco frame respectively. The photoelectric equipment can emit and receive infrared light, and judge the stacking height of the tobacco leaves in the tobacco frame by detecting the obstruction of light; when the three sets of photoelectric equipment detect that the light is blocked at the same time, the system determines that the tobacco frame is full. At this time, the system triggers the tobacco frame throwing station action, and moves the tobacco frame smoothly from the leaf selection unit to the solid frame transfer line to avoid the tobacco frame being too full and affecting the sorting efficiency and tobacco leaf quality.

[0060] The tobacco frame transfer tracking system automatically binds the tobacco leaf's grade information, leaf selection group information and origin information to the tobacco frame's information carrier. After the selected tobacco leaves complete re-inspection, the tobacco frame information is erased and enters the empty frame transfer line.

[0061] It should be noted that, similar to the tobacco frame information binding station, the tobacco frame transfer tracking system reconfirms and binds basic information such as tobacco leaf grade information, leaf selection group information, and origin to the tobacco frame information carrier during the tobacco frame transfer process. At the same time, the system updates the tobacco frame location information in real time to ensure full tracking of the tobacco frame. After the selected tobacco leaves are re-inspected, the system automatically erases the relevant information in the tobacco frame information carrier, restoring the tobacco frame to its initial blank state. The empty frame is then transported to each sorting group through the empty frame transfer line, ready for the next round of tobacco frame loading.

[0062] The dynamic allocation system for quality inspection stations initializes the grouping of re-inspection stations based on historical batch data and historical percentage data, and splits the maximum level into multiple re-inspection stations for balancing; if the number of levels is greater than the number of re-inspection stations, a high-low ratio match is first performed, and then a larger level is selected for dynamic balancing to balance the flow of cigarette frames at each re-inspection station and reduce the possibility of congestion. At the same time, statistics are collected on the levels of cigarette frames and the number of each level on the selected cigarette frame transfer line, and real-time allocation of re-inspection station levels is performed based on this real-time data.

[0063] It should be noted that the system initializes the grouping of re-inspection stations based on historical batch data and historical percentage data, splitting the largest grade of cigarette frames to multiple re-inspection stations for balanced distribution, to avoid congestion caused by a certain re-inspection station processing a large number of cigarette frames of the same grade. If the number of grades is greater than the number of re-inspection stations, the system will first match the high and low ratios, that is, reasonably distribute the cigarette frames of different grades to each re-inspection station, and then select a larger grade for dynamic balancing, to further optimize the cigarette frame flow of each re-inspection station; the system will conduct real-time statistics on the grade of cigarette frames and the number of each grade on the selected cigarette frame transfer line. Based on the real-time statistical data, the system will dynamically adjust the grade distribution of the re-inspection stations to ensure that the workload of each re-inspection station is relatively balanced, reduce the possibility of congestion, and improve quality inspection efficiency.

[0064] Working principle: When the present invention is used, the material is loaded through the sack robot, and then the sack code is scanned and transported to each sorting station through the sack transfer line. The leaves are manually selected and loaded into small cigarette boxes and given tobacco leaf grade and sorting group information, and sent to the post-selection tobacco frame transfer line. During the tobacco leaf sorting process, once unqualified tobacco leaves are found, they will be immediately returned to the leaf selection station; in the process of transporting qualified tobacco leaves on the tobacco frame transfer line, they will pass through the code reading and weighing equipment. The code reading equipment can quickly read the information on the small cigarette box and confirm the tobacco leaf grade and sorting group data. The small cigarette boxes that have been read and weighed are sent to the quality inspection station for strict quality inspection; after the quality inspection is completed, the framing operation is carried out according to the tobacco leaf grade. The remaining empty cigarette boxes after framing enter the empty frame column logistics channel. After the empty cigarette box enters the channel, the system will eliminate the tobacco leaf information stored on it and restore it to its initial blank state; then, the empty cigarette box is sent to each sorting station to achieve recycling, reduce production costs, and improve resource utilization efficiency.

[0065] In summary, the present invention can achieve efficient, precise and intelligent management of the tobacco leaf sorting process, improve tobacco leaf sorting quality and production efficiency, and reduce labor costs and labor intensity.

[0066] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.

The full-frame detection system consists of three groups of photoelectric devices, which are used to detect in real time whether tobacco leaves are exceeding the front, middle and rear ends of the frame. When obstruction is detected at the same time, the frame is considered full. When the frame is full, the frame is ejected from the selection unit to the full-frame transfer line. The tobacco frame transfer tracking system automatically binds the grade information, leaf selection group information and origin information of the tobacco leaves to the information carrier of the tobacco frame. After the selected tobacco leaves have completed the re-inspection, the tobacco frame information is erased and the leaves enter the empty frame transfer line. The dynamic allocation system for quality inspection stations initializes the grouping of re-inspection stations based on historical batch data using historical percentage data, and splits the maximum level into multiple re-inspection stations for balancing. If the number of levels is greater than the number of re-inspection stations, a high-low ratio match is first performed, and then a larger level is selected for dynamic balancing to balance the flow of cigarette frames at each re-inspection station. At the same time, statistics are collected on the levels of cigarette frames and the number of each level on the selected cigarette frame transfer line, and real-time allocation of re-inspection station levels is performed based on this real-time data.

8. The intelligent dynamic scheduling system for a universal sorting line according to claim 7, characterized in that: The universal sorting line is divided into 24 areas, and the areas are graded through the management system. The sorting line is controlled by a servo motor, and the position of tobacco leaves in each area is recorded and tracked through an encoder and an electronic control system. At the same time, an identification plate is set in each area for manual identification of the area grade.

9. The intelligent dynamic scheduling system for a universal sorting line according to claim 7, characterized in that: The jute bag transfer line passes through each sorting table. The information system allocates the sorting line and the loading port according to the origin, grade and batch of the original tobacco. The electronic tag of the cigarette frame is manually scanned at the loading port to verify the information, and the jute bag is manually placed on the conveyor line. During the transfer process, the jute bag information is read and transmitted to the electronic control system. The electronic control system tracks the jute bag on the conveyor line. When it arrives at the designated leaf selection table, it is pushed out by the tobacco pushing mechanism and slides to the circular jute bag table.

10. The intelligent dynamic scheduling system for a universal sorting line according to claim 7, characterized in that: The solid frame transfer line collects the solid frames of multiple leaf selection units and transfers them to the quality inspection station. The climbing and descending processing are set according to the flow. A dynamic allocation system for the quality inspection station is provided from the solid frame transfer line to the quality inspection station, which intelligently allocates the selected cigarette frames by identifying the flow of the quality inspection station.
