Description

Technical Field

[0001] This utility model relates to the field of tobacco processing equipment technology, specifically to an intelligent dynamic scheduling device applied to a universal sorting line. Background Technology

[0002] As the industry comprehensively promotes high-quality development of tobacco leaves, the requirements for tobacco raw materials are becoming increasingly stringent, and the production philosophy is shifting towards a focus on both quality and efficiency. The industry is continuously increasing its investment in the automation and intelligentization of production processes. However, currently, tobacco leaf sorting in China is mainly still in the stage of assembly line-style manual sorting and purely manual sorting, with limited automated machinery in the sorting process. During the sorting process, auxiliary tasks such as transporting bales to the sorting table and sending sorted tobacco leaves to the quality inspection station are still primarily done manually. In the 2024 tobacco curing season at the Shilin Re-drying Plant, a total of 510 people were involved in the sorting process, of which only 360 were sorting workers. The remaining 150 were responsible for auxiliary sorting tasks such as bale loading, quality inspection, and cleaning, resulting in low efficiency. Currently, a few re-drying plants have introduced circular sorting lines for transporting bales and sorted tobacco leaves, but these all suffer from the following problems: (1) Most of the existing ring sorting line equipment are fixed conveyor lines, which only play the function of material conveying. They cannot dynamically adjust the material distribution according to the load of the sorting table and the quality inspection table, and do not realize the intelligent distribution of materials, which can easily cause local congestion or idleness.

[0003] (2) Existing circular sorting lines are unable to form a closed information loop for tobacco leaf sorting and can only realize basic transportation functions. At the same time, existing circular sorting lines often only support the sorting of tobacco leaves of 5 grades or less, but for re-drying plants with import and export tobacco leaf processing requirements, more than 10 grades need to be sorted at once, which existing circular sorting lines cannot meet.

[0004] (3) The existing circular sorting line still requires a lot of manual labor to complete auxiliary work, and the utilization rate of manual labor is not high.

[0005] Therefore, in view of the shortcomings of the existing circular sorting line, there is an urgent need to propose a sorting line that can realize intelligent dynamic scheduling and meet the requirements of multi-level sorting. Utility Model Content

[0006] The purpose of this invention is to provide an intelligent dynamic scheduling device for use in universal sorting lines, in order to solve the technical problems existing in traditional tobacco leaf sorting processes, such as high dependence on manual labor, rigid material scheduling, lack of information traceability, and lack of support for intelligent scheduling for quality inspection.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an intelligent dynamic scheduling device for 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-sorting quality inspection table, and a post-sorting loading area. The burlap bale transfer line is used for transferring burlap bales. During the transfer process, the burlap bale information is read and transmitted to the electronic control system. The electronic control system tracks the conveyor line, and when it reaches the designated leaf selection table, it is pushed out to the circular burlap bale table by the tobacco pushing mechanism. The solid frame transfer line is used to load the tobacco frames after selection and transfer them to the quality inspection station. The solid frame transfer line gathers the solid frames from multiple leaf selection units and transfers them to the quality inspection station. The empty frame transfer line is used to transport the empty smoke frames after the selected smoke frame information has been erased to each sorting group; the solid frame transfer line and the empty frame transfer line are divided into upper and lower layers, and the solid frame transfer line and the empty frame transfer line are respectively set between two rows of sorting tables, with the upper layer being the empty frame transfer line and the lower layer being the solid frame transfer line. The universal sorting table consists of 6 small sorting tables, a burlap sack storage table, a manual ladder, and a tobacco frame loading table. The 6 small sorting tables are used to accommodate 12 leaf sorting personnel for operation. The burlap sack storage table is used for temporary storage of burlap sacks. The manual ladder is used for personnel to enter and exit the leaf sorting unit. The tobacco frame loading table is circular in shape and is used to place tobacco frames of more than 20 grades. The post-selection quality inspection station is used to inspect the quality of the selected tobacco leaves; The selected framing area is used for framing tobacco leaves according to their grade.

[0008] Preferably, the conveyor lines are designed with an elevation, and the conveyor lines are divided into three layers: a first layer, a second layer, and a burlap layer. The first layer is a temporary storage line for the selected tobacco frames, with a height of 180mm; the second layer is a manual working platform with a height of 760mm; and the burlap layer has a height of 1900mm to optimize the working space for leaf selectors. Part of the transfer line passes under the inclined tie rod.

[0009] Preferably, the burlap sack transfer line has an intelligent interface for connecting the burlap sacks to the robotic arm.

[0010] Preferably, the post-selection quality inspection station has an interface for intelligent quality inspection equipment for subsequent access of intelligent quality inspection equipment, and a robot arm access point is provided behind the post-selection quality inspection station for access of the robot arm.

[0011] Preferably, the specifications of the six small sorting tables are: 1800mm in length, 1600mm in width, and 700mm in height; the radius of the burlap sack temporary storage table is 1750mm, which is used to connect the burlap sack conveyor line; the height of the tobacco frame loading table is 180mm and the width is 1600mm, and the outside of the tobacco frame loading table is the empty tobacco frame conveyor line.

[0012] Preferably, the solid frame transfer line in the leaf selection area is at the same horizontal level as the solid frame transfer line, and after the empty frame line reaches the leaf selection unit, it slopes down to be at the same horizontal level as the solid frame transfer line.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention reduces the manpower required in the sorting process and adopts dynamic logistics scheduling. Based on the real-time flow of leaf-sorting unit sacks, empty smoke frames, and small smoke frames of different grades, as well as the real-time flow of small smoke frames of different grades on the quality inspection station, dynamic control and flexible processing of materials are achieved through intermediate logistics links, avoiding material accumulation and congestion, and realizing dynamic balance of logistics within the system.

[0014] This invention employs a universal sorting table, solving the problem of supporting a limited number of sorting grades after initial selection. It enables simultaneous and efficient picking of up to 24 arbitrary grades, achieving "box-to-person" sorting via a universal conveyor line, avoiding manual back-and-forth movement. Furthermore, the cigarette boxes can be combined according to different sorting volumes: multiple boxes for large batches and 1-2 boxes for small batches, dynamically adjusting based on batch size to improve system flexibility and adaptability. This meets the refined, modular, and homogenized processing needs of industrial enterprises for raw tobacco.

[0015] This invention can record sorting, quality inspection, and packing data in real time. It adopts a variety of intelligent recognition technologies and collects data in real time to ensure the correct reading and writing of information for each link, process, and material. Through the upper-level material management system, it improves the granularity of management, enhances the macro-control and dynamic adjustment of the leaf selection process by managers, and realizes digital governance.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This utility model provides a technical solution: an intelligent dynamic scheduling device applied to a universal sorting line, including a sack transfer line, a full frame transfer line, an empty frame transfer line, a universal sorting table, a post-sorting quality inspection table, and a post-sorting loading area. The burlap bale transfer line is used for transferring burlap bales. During the transfer process, the burlap bale information is read and transmitted to the electronic control system. The electronic control system tracks the conveyor line, and when it reaches the designated leaf selection table, it is pushed onto the circular burlap bale table by the tobacco pushing mechanism.

[0019] It should be noted that an electronic tag scanning device is installed at the feeding port of the burlap bales. When a person manually places a burlap bale at the feeding port, the scanning device automatically reads the electronic tag information on the bale and transmits the information to the electronic control system. The electronic control system accurately allocates the burlap bales to the corresponding sorting lines and feeding ports based on information such as the origin, grade, and batch of the raw tobacco. During the transfer process, the electronic control system tracks the position of the burlap bales in real time through sensors installed on the conveyor line. When the burlap bale reaches the designated leaf sorting table, the electronic control system controls the tobacco pushing mechanism to push the burlap bale off the conveyor line and slide it onto the circular burlap bale table for easy access by the leaf sorting personnel.

[0020] The solid frame transfer line is a conveyor line used to load the selected tobacco leaves into frames and transfer them to the quality inspection station. The solid frame transfer line gathers the solid frames from multiple leaf selection units and transfers them to the quality inspection station.

[0021] It should be noted that the solid frame transfer line can be configured with ramping and deceleration based on the smoke flow rate. 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. The solid frame transfer line is equipped with a dynamic allocation system for the quality inspection station. By identifying the flow rate at the quality inspection station, the system intelligently allocates selected smoke frames, reducing congestion or idle time at the quality inspection station. The dynamic allocation system initializes the re-inspection stations based on historical batch data and historical percentage data. The highest grade is then split into multiple re-inspection stations for balancing. If the number of grades exceeds the number of re-inspection stations, a high-low ratio is first matched, and then a larger grade is selected for dynamic balancing. This balances the smoke frame flow rate across each re-inspection station, reducing the possibility of congestion.

[0022] The empty frame transfer line is used to transport the empty smoke frames after the selected smoke frame information has been erased to each sorting group; the full frame transfer line and the empty frame transfer line are divided into upper and lower layers, and the full frame transfer line and the empty frame transfer line are respectively set between the two rows of sorting tables, with the upper layer being the empty frame transfer line and the lower layer being the full frame transfer line.

[0023] It should be noted that the solid frame transfer line and the empty frame transfer line are divided into two layers, set 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. This layered design effectively utilizes space and avoids line crossing and interference. The empty frame transfer line is responsible for transporting the empty tobacco frames after the information of the selected tobacco frames has been erased to each sorting group. After the empty frames arrive at the leaf sorting unit, they are lowered to the same level as the solid frame transfer line by a slope lowering device, making it convenient for leaf sorting personnel to take the empty frames for the next round of tobacco leaf packing.

[0024] The universal sorting table consists of 6 small sorting tables, a burlap sack storage table, a manual ladder, and a tobacco frame loading table. The specifications of the 6 small sorting tables are all: 1800mm in length, 1600mm in width, and 700mm in height. The burlap sack storage table has a radius of 1750mm and is used to connect to the burlap sack conveyor line. The tobacco frame loading table has a height of 180mm and a width of 1600mm, and the outside of the tobacco frame loading table is the empty tobacco frame conveyor line.

[0025] It should be noted that one omnidirectional sorting table constitutes a team, consisting of 6 small sorting tables, a burlap sack storage table, a manual ladder, and a tobacco frame loading table. These components work together to provide an efficient and convenient working environment for leaf sorting personnel. The 6 small sorting tables are all 1800mm long, 1600mm wide, and 700mm high. Their dimensions and height are rationally designed to allow two people to sort the tobacco leaves simultaneously. Sorting personnel meticulously sort the tobacco leaves taken from the burlap sacks on these small sorting tables. The tobacco frame loading table is circular, located around the small sorting tables, with a height of 180mm and a width of [missing information]. The 1600mm rotating tobacco frame loading table can accommodate more than 20 grades of tobacco frames, allowing different grades of tobacco leaves produced by each leaf sorting station to be placed into the corresponding grade of plastic tobacco frames without personnel moving. The empty tobacco frame conveyor line is located outside the tobacco frame loading table, facilitating timely replenishment of empty frames. A manual ladder is set 500-600mm away between the leaf sorting table and the universal sorting line, allowing leaf sorting personnel to enter and exit the leaf sorting unit in a unified manner, ensuring orderly and safe personnel flow. The post-selection quality inspection station is used to inspect the quality of selected tobacco leaves.

[0026] 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.

[0027] The post-selection framing area is used for framing tobacco leaves according to their grade.

[0028] It should be noted that the post-selection and framing area classifies and frames tobacco leaves according to their grade. Following the pre-set framing rules, the quality-inspected tobacco leaves are loaded into the corresponding frames to prepare for subsequent storage and transportation.

[0029] The device incorporates a facade design for each conveyor line, comprising three layers: Layer 1, Layer 2, and the burlap sack layer. Layer 1 serves as a temporary storage line for the selected tobacco frames, with a height of 180mm, for temporary storage. Layer 2 is a manual working platform, 760mm high, providing a comfortable working height for leaf selectors. The burlap sack layer, with a height of 1900mm, optimizes the working space for leaf selectors and facilitates easy access to the burlap sacks. During the conveyor line design, coordination with the civil engineering structure was carefully considered. Some transfer lines need to pass under inclined tie rods; through precise measurement and design, it was ensured that the conveyor lines do not conflict with the civil engineering structure, guaranteeing the stable operation of the entire system. The lower surface of the raw tobacco bale transfer line is 1800mm high, allowing personnel to work below. The tobacco bales slide down to the bale storage disc via a slope-depressing non-powered conveyor. The tail end of the slope-depressing conveyor is offset to one side at a certain angle to ensure that the bales do not roll during the descent and can accurately land on the edge of the round table for easy retrieval by leaf selectors. The solid frame transfer line in the leaf selector area is at the same level as the leaf selector unit, ensuring that the tobacco frames loaded with selected tobacco leaves can smoothly enter the leaf selector unit for subsequent processing. After the empty frame line reaches the leaf selector unit, it is lowered by a slope-depressing device to be at the same level as the solid frame transfer line, achieving a smooth handover between empty and solid frames.

[0030] Working Principle: The system uses a robotic arm to load the sacks, which are then scanned and transported via a sack transfer line to various sorting stations. Manual sorting of the leaves is performed, and each sack is placed into a small tobacco box, labeled with its grade and sorting group information. These boxes are then sent to the post-sorting frame transfer line. During the sorting process, any unqualified leaves are immediately returned to the sorting station. On the frame transfer line, qualified leaves pass through a barcode-reading and weighing device. This device quickly reads the information on the small tobacco boxes, confirming the grade and sorting group data. The weighed boxes are then sent to the quality inspection station for rigorous quality control. After inspection, the leaves are framed according to grade. Empty tobacco boxes enter the empty frame logistics channel. Upon entering the channel, the system removes the stored leaf information, restoring the boxes to their initial blank state. The empty boxes are then sent to the various sorting stations, achieving recycling, reducing production costs, and improving resource utilization efficiency.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
