[0018] Optionally, in the four-way shuttle transporting step, the four-way shuttle identifies the category of the obstacle from the image acquired by the visual sensor based on the image recognition algorithm of machine learning, and combines the distance data of the lidar and ultrasonic sensor to determine the specific position of the obstacle in the coordinate system of the four-way shuttle through coordinate transformation and spatial calculation, and calculates the azimuth and distance parameters of the obstacle relative to the four-way shuttle.

[0019] Optionally, the cigarette auxiliary material dispatching method further comprises the following steps:

[0020] The steps for sampling and inventory of auxiliary materials include the following steps:

[0021] Cargo space allocation step: The warehouse management system issues a sampling / inventory counting instruction and simultaneously allocates a cargo space for the sampling / inventory counting task for outbound operation;

[0022] The four-way shuttle picks up materials: The four-way shuttle goes to the corresponding location according to the assigned cargo location information to pick up the cigarette auxiliary material pallet, and then transports it along the four-way shuttle track to the reciprocating elevator in the auxiliary material balance warehouse outbound area, and then descends to the cargo release platform in the outbound area through the reciprocating elevator;

[0023] Inspection and processing steps: The cigarette auxiliary material pallets are sent to the sampling / inventory station through the cargo release station and conveyor system for corresponding inspection and processing operations;

[0024] Return storage steps: After the inspection and processing, the cigarette auxiliary material pallet is sent to the conveyor line of the bulk pallet return platform through the conveying system, lifted to the designated shelf layer by the reciprocating elevator, and finally stored in the cargo position reallocated by the system by the four-way shuttle car.

[0025] Optionally, in the cargo location allocation step, after the warehouse management system issues the sampling / inventory counting instruction, the rules for allocating cargo locations are based on comprehensively determining the sampling ratio and inventory counting scope based on the variety category of cigarette excipients, batch information of cigarette excipients, and the order of the cigarette excipients' entry into storage.

[0026] According to a second aspect of the present invention, a cigarette auxiliary material outbound dispatching system is provided, comprising:

[0027] An application initiation module, used to obtain a material request containing information on cigarette auxiliary materials transmitted through a material request terminal;

[0028] The outbound dispatching module generates auxiliary material outbound tasks according to the material request through the warehouse management system, and forwards the auxiliary material outbound tasks to the warehouse control system;

[0029] The first handling module directs the four-way shuttle to go to the designated cargo position assigned by the warehouse management system, grabs the cigarette auxiliary material pallet, and then transports the cigarette auxiliary material pallet along the track of the four-way shuttle to the reciprocating elevator in the outbound area of ​​the auxiliary material balance warehouse, and then descends to the cargo release platform in the outbound area through the reciprocating elevator;

[0030] The second handling module dispatches the forklift AGV to the outbound platform, picks up the cigarette auxiliary material pallets waiting for handling, and transports them to the corresponding rolling and packaging workshop machines.

[0031] Optionally, the outbound platform includes three branched outbound platforms, namely a first outbound platform, a second outbound platform and a third outbound platform;

[0032] The first outbound platform is used as a normal outbound platform in the normal outbound operation mode, and is used as a sampling / inventory platform in the sampling / inventory operation mode, and the function switching of the first outbound platform is automatically controlled and executed by the warehouse control system;

[0033] The second outbound platform is used as an outbound platform in the normal outbound mode, and can be used as a bulk pallet return platform in the bulk pallet return operation mode, for receiving and processing the return operation of bulk pallet auxiliary materials, and the function switching of the second outbound platform is automatically controlled and executed by the warehouse control system;

[0034] The third outbound platform is used as an outbound platform in the normal outbound mode and as an empty pallet return platform in the empty pallet return operation mode, and the function switching of the third outbound platform is automatically controlled and executed by the warehouse control system.

[0035] The cigarette auxiliary material outbound dispatching method and system disclosed in the present invention have the following technical effects:

[0036] In the technical solution of the present invention, the machine in the wrapping workshop initiates an application in advance through the material request terminal according to the production situation. The warehouse management system automatically calculates the types of auxiliary materials suitable for the model of the wrapping machine and allocates specific cargo locations. The warehouse control system dispatches a four-way shuttle to transport the auxiliary material pallets from the designated cargo locations out of the warehouse and automatically transports them to the machine in the wrapping workshop. When random inspection / inventory is required, the system automatically dispatches the auxiliary material pallets out of the warehouse and automatically returns them to the warehouse after inspection. The present invention is based on a data-driven model that accurately matches machines and auxiliary materials, avoiding auxiliary material supply errors caused by human misjudgment or poor information communication. The warehouse management system allocates specific cargo locations and the warehouse control system dispatches the four-way shuttle to transport and automatically transport to the machine, which greatly shortens the time cycle for auxiliary material supply.

[0037] The warehouse management system takes into account many factors when allocating cargo spaces, such as the storage status of the cargo spaces, the logistics path planning within the warehouse, and the distance to the packaging workshop, etc. This allows the warehouse space to be used more reasonably, avoiding the situation where some cargo spaces are over-occupied while others are idle.

[0038] It is possible to understand the usage of cargo space in real time, and to adjust the cargo space arrangement more flexibly when conducting random inspections / inventory or other special situations.

[0039] From the material request initiated by the wrapping machine to the delivery and return of auxiliary materials to the warehouse after sampling / inventory, the system updates the inventory data in real time throughout the entire process. The operation of each link will be accurately recorded and reflected in the warehouse management system, so that the inventory information is always kept up to date, improving the accuracy of inventory management and reducing the errors and omissions that may be caused by manual operations.

DETAILED DESCRIPTION

[0047] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0048] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0049] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0050] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0051] The present invention proposes an embodiment of a method for dispatching cigarette auxiliary materials out of warehouse. Specifically, Figure 1 As shown, the following steps are included:

[0052] Application initiation step: obtaining a material request containing information about cigarette auxiliary materials transmitted through a material request terminal, wherein the machine personnel in the rolling and packaging workshop input the required auxiliary material information into the material request terminal, including the specific types of cigarette auxiliary materials required, such as cigarette paper, filter tip, packaging materials of specific specifications, the required quantity and the corresponding rolling and packaging machine number;

[0053] Outbound dispatching steps: The warehouse management system generates outbound tasks for auxiliary materials based on the material request, and forwards the outbound tasks to the warehouse control system. Outbound tasks for auxiliary materials include but are not limited to the pick-up location, pallet information, and the location information of the roll-wrapping machine in the auxiliary material balance warehouse. For example, for a specific filter auxiliary material requested by a certain model of roll-wrapping machine, the system will quickly query the storage location, quantity, and quality status of the specific filter auxiliary material in the inventory to determine whether the request can be met. If the inventory is sufficient, the system will formulate a detailed outbound task plan for auxiliary materials based on multiple factors such as the location of the roll-wrapping machine, the warehouse layout, and the operating status of the current logistics equipment.

[0054] The four-way shuttle vehicle transportation steps: the warehouse control system directs the four-way shuttle vehicle to go to the designated cargo location assigned by the warehouse management system, grab the cigarette auxiliary material pallet, and then transport the cigarette auxiliary material pallet along the track of the four-way shuttle vehicle to the reciprocating elevator in the outbound area of ​​the auxiliary material balance warehouse, and then descend to the cargo release platform in the outbound area through the reciprocating elevator in the outbound area; among them, the four-way shuttle vehicle uses its efficient grabbing mechanism to accurately grab the cigarette auxiliary material pallet. The grabbing mechanism adopts structures such as mechanical arms, suction cups or forklift forks, and can be adaptively adjusted according to the shape, size and weight of different pallets.

[0055] Forklift AGV handling steps: The warehouse control system dispatches the forklift AGV to the outbound platform, picks up the cigarette auxiliary material pallet waiting for transportation, and transports it to the corresponding rolling and packaging workshop machine. After arriving at the machine, the forklift AGV places the pallet in the designated loading area of ​​the machine, making it convenient for the operators in the rolling and packaging workshop to take the auxiliary materials. This completes the entire cigarette auxiliary material outbound dispatching process, ensuring the timely and accurate supply of auxiliary materials on the cigarette production line.

[0056] In an embodiment of the present invention, after the four-way shuttle vehicle transporting step, the method further includes:

[0057] Information verification steps: The cigarette auxiliary material pallet is transported from the loading station to the outbound station via the conveyor line. The cigarette auxiliary material pallet undergoes barcode / RFID information verification at the outbound station. If the verification result is abnormal, the abnormal cigarette auxiliary material pallet is sent to the designated storage location by the conveying system, the reciprocating elevator in the outbound area, and the four-way shuttle. If the verification result is normal, it is placed in a waiting state. The warehouse management system performs consistency comparison on the barcode / RFID information based on the pre-stored database information, for example, checking whether the batch of cigarette paper is recorded in the system, whether its manufacturer is a qualified supplier, whether the global unique identification code in the label is consistent with the storage registration information of the corresponding auxiliary material in the system, and whether the storage time is in line with expectations.

[0058] In the embodiment of the present invention, in the outbound dispatching step, the warehouse management system sets the cigarette auxiliary material pallets that are in balance within 24 hours to a locked state, and automatically unlocks them after 24 hours for production use. Ensuring that the pallets of cigarette auxiliary materials will not be dispatched out of the warehouse at will within a certain period of time helps warehouse managers to better plan inventory and avoid inventory shortages or backlogs caused by excessive allocation.

[0059] In the embodiment of the present invention, in the outbound dispatching step, the method by which the warehouse management system determines the cargo location when dispatching outbound is determined based on the following factors:

[0060] The storage status of each cargo space in the warehouse, including whether each cargo space is currently occupied, the type and quantity of cigarette accessories stored, and the remaining available space;

[0061] Logistics path planning inside the warehouse, including shelf arrangement, aisle width and direction, and running tracks for four-way shuttles and forklift AGVs;

[0062] The distance information between different cargo positions and the rolling and packaging workshop includes the physical distance between the cargo position and the rolling and packaging workshop, whether there is a slope, the number and curvature of the curves, and whether it is necessary to cross other special areas (such as areas with high temperature and humidity control requirements, which may affect the handling speed and equipment performance). By comprehensively integrating the storage status of each cargo position in the warehouse, the logistics path planning inside the warehouse, and the distance information between different cargo positions and the rolling and packaging workshop, the warehouse management system can accurately determine the most suitable cargo position for the outbound task of cigarette auxiliary materials, thereby realizing an efficient and smooth outbound operation process, minimizing the outbound time, and improving the operational efficiency of the entire warehouse logistics system.

[0063] In an embodiment of the present invention, in the four-way shuttle transport step, the four-way shuttle identifies the category of obstacles from the images obtained by the visual sensor based on the image recognition algorithm of machine learning, and combines the distance data of the laser radar and ultrasonic sensor to determine the specific position of the obstacle in the coordinate system of the four-way shuttle through coordinate conversion and spatial calculation, and calculates the azimuth and distance parameters of the obstacle relative to the four-way shuttle, so as to provide an accurate basis for the subsequent obstacle avoidance strategy formulation. During the transport process, the four-way shuttle comprehensively evaluates the potential risk degree of the obstacle to the operation of the shuttle based on factors such as the distance, size, moving speed (for movable obstacles) and the driving speed of the shuttle itself. The control system of the four-way shuttle is also provided with a multi-task coordination module for coordinating the relationship between the two tasks of speed adjustment and route change to ensure that they cooperate with each other and do not conflict with each other during the execution process.

[0064] In an embodiment of the present invention, the cigarette auxiliary material outbound dispatching method further includes the following steps:

[0065] The steps for sampling and inventory of auxiliary materials include the following steps:

[0066] Cargo space allocation step: The warehouse management system issues a sampling / inventory counting instruction and simultaneously allocates a cargo space for the sampling / inventory counting task for outbound operation;

[0067] The four-way shuttle picks up materials: The four-way shuttle goes to the corresponding location according to the assigned cargo location information to pick up the cigarette auxiliary material pallet, and then transports it along the four-way shuttle track to the reciprocating elevator in the outbound area of ​​the auxiliary material balance warehouse, and then descends to the cargo release platform in the outbound area through the reciprocating elevator in the outbound area;

[0068] Inspection and processing steps: The cigarette auxiliary material pallets are sent to the sampling / inventory station through the cargo release station and conveyor system for corresponding inspection and processing operations;

[0069] Return storage steps: After the inspection and processing, the cigarette auxiliary material pallet is sent to the conveyor line of the return platform through the conveying system, and is lifted to the designated shelf layer by the reciprocating elevator in the return area. Finally, the four-way shuttle car stores the cigarette auxiliary material pallet in the cargo space reallocated by the system.

[0070] In an embodiment of the present invention, in the cargo location allocation step, after the warehouse management system issues the sampling / inventory instruction, the rule for allocating cargo locations is to comprehensively determine the sampling ratio and inventory range based on the category of cigarette auxiliary materials, the batch information of cigarette auxiliary materials, and the order of the storage time of cigarette auxiliary materials. Taking into account the above factors such as the category of cigarette auxiliary materials, batch information, and the order of storage time, the warehouse management system can accurately determine the sampling ratio and inventory range corresponding to each cargo location, so as to allocate cargo locations for sampling / inventory operations in a targeted manner. For example, for a certain key variety and a new batch of cigarette auxiliary materials that have been recently stored, cargo locations close to the sampling area and easy to carry will be preferentially allocated, so that samples can be extracted and tested quickly and efficiently during the sampling process; and for those non-key varieties and auxiliary materials that have been stored earlier but have good past sampling records, relatively remote cargo locations will be allocated for inventory. Under the premise of ensuring the accuracy of inventory, the logistics operation process inside the warehouse is reasonably optimized to improve the overall storage management efficiency and resource utilization efficiency.

[0071] The present invention also provides an embodiment of a cigarette auxiliary material dispatching system, specifically as follows Figure 2 and Figure 3 As shown, the system includes:

[0072] An application initiation module, used to obtain a material request containing information on cigarette auxiliary materials transmitted through a material request terminal;

[0073] The outbound dispatching module generates auxiliary material outbound tasks according to the material request through the warehouse management system, and forwards the auxiliary material outbound tasks to the warehouse control system; it should be noted that the warehouse management system automatically calculates and allocates auxiliary material pallets suitable for the production area according to the model of the roll-wrapping machine 5 that initiated the application, and forwards the outbound tasks to the warehouse control system;

[0074] The first handling module directs the four-way shuttle 6 to the designated cargo position assigned by the warehouse management system, grabs the cigarette auxiliary material pallet, and then transports the cigarette auxiliary material pallet along the track of the four-way shuttle 6 to the reciprocating elevator 3 in the outbound area of ​​the auxiliary material balance warehouse 4. After the electric control system detects the in-position signal, the auxiliary material pallet is lowered to the cargo release platform 7 in the outbound area through the reciprocating elevator 3 in the outbound area;

[0075] The second transport module dispatches the forklift AGV1 to go to the outbound platform 2, picks up the cigarette auxiliary material pallet in a waiting state, and transports it to the corresponding packaging machine 5.

[0076] Among them, the auxiliary material pallet is transported to the inspection station 10 via the conveyor line, and the barcode / RFID information is verified at the inspection station 10. When the auxiliary material pallet information is detected abnormally, the electric control system controls the conveyor line of the inspection station 10 to reverse, and the auxiliary material pallet returns to the main conveyor line 8, and is transported to the reciprocating elevator 9 for return to the warehouse via the conveyor lines of the second outbound platform (loose pallet return platform) 22 and the third outbound platform (empty pallet return platform) 23. After the electric control system detects that it is in place, the reciprocating elevator 9 rises to the designated shelf layer. At the same time, the warehouse control system dispatches the four-way shuttle 6 to the reciprocating elevator 9 in the return area to pick up the auxiliary material pallet and send it to the designated cargo location allocated by the warehouse management system for storage. The auxiliary material pallet that is detected to be normal is transported to the outbound platform 2, waiting for the forklift AGV1 to move it. The warehouse control system issues instructions to the forklift AGV1 system, dispatching the forklift AGV1 to the outbound platform 2. When the forklift AGV1 runs to the outbound platform 2 according to the preset route, the fork arm is raised to the same height as the center of the chuan-shaped hole of the auxiliary material pallet on the outbound platform 2. After the fork arm is fully extended into the chuan-shaped hole of the pallet, it is lifted upward to a certain height, the auxiliary material pallet is moved, and it retreats to the designated position. The fork arm carrying the auxiliary material pallet is lowered to a low position and sent to the corresponding material request machine in the winding and packaging workshop at the same time.

[0077] The warehouse management system issues a sampling / inventory-taking instruction, the system allocates the cargo location for outbound delivery, and forwards the outbound delivery task to the warehouse control system. The warehouse control system dispatches the four-way shuttle 6 to the designated cargo location to pick up the auxiliary material pallet, and transports it along the track of the four-way shuttle 6 to the reciprocating elevator 3 in the outbound delivery area of ​​the auxiliary material balance warehouse 4. After the electric control system detects the in-position signal, the reciprocating elevator 3 in the outbound delivery area descends to the delivery platform 7 in the outbound delivery area. The auxiliary material pallet is sent to the first outbound delivery platform (sampling / inventory-taking platform) 21 through the conveying system, and is manually inspected and processed accordingly.

[0078] After the inspection is completed, the manual confirmation is carried out in the warehouse management system. The warehouse management system generates a return task and forwards it to the warehouse control system. The warehouse control system issues instructions to the electronic control system to control the reverse of the conveyor line of the sampling / inventory platform 21, and convey the auxiliary material pallet to the main conveyor line 8, and then transport it to the reciprocating elevator 9 for return through the conveyor lines of the second outbound platform (loose pallet return platform) 22 and the third outbound platform (empty pallet return platform) 23. After the electronic control system detects that it is in place, the reciprocating elevator 9 in the return area rises to the designated shelf layer. At the same time, the warehouse control system dispatches the four-way shuttle 6 to the reciprocating elevator 9 in the return area to pick up the auxiliary material pallet and send it to the designated storage location reallocated by the warehouse management system for storage.

[0079] In the embodiment of the present invention, the outbound platform 2 at the auxiliary material balance warehouse 4 includes three branched outbound platforms, namely the first outbound platform 21, the second outbound platform 22 and the third outbound platform 23; wherein the first outbound platform 21 is used as a sampling / inventory platform, the second outbound platform 22 is used as a bulk pallet return platform, and the third outbound platform 23 is used as an empty pallet return platform;

[0080] The first outbound platform 21 is used as a normal outbound platform in the normal outbound operation mode to realize the normal outbound transportation operation of the auxiliary material pallet, and is used as a sampling / inventory platform in the sampling / inventory operation mode to perform sampling or inventory-related operation processes on specific auxiliary material pallets, and the function switching of the first outbound platform 21 is automatically controlled and executed by the warehouse control system;

[0081] The second outbound platform 22 is used as an outbound platform in the normal outbound mode, and can be used as a bulk pallet return platform in the bulk pallet return operation mode, for receiving and processing the return operation of bulk pallet auxiliary materials, and the function switching of the second outbound platform 22 is automatically controlled and executed by the warehouse control system;

[0082] The third outbound platform 23 is used as an outbound platform in normal outbound mode and as an empty pallet return platform in empty pallet return operation mode, for receiving and processing the return operation of empty pallets, and the function switching of the third outbound platform 23 is automatically controlled and executed by the warehouse control system.

[0083] The warehouse control system includes a platform function control module, which establishes communication connections with the first outbound platform 21, the second outbound platform 22, and the third outbound platform 23, respectively, for receiving operation mode instructions from the outside, and controlling the function switching of the corresponding outbound platform according to the instruction content, wherein the operation mode instructions include normal outbound instructions, sampling / inventory instructions, loose pallet return instructions, and empty pallet return instructions. Each outbound platform is equipped with a detection and identification device for identifying the type and status information of the auxiliary material pallet or empty pallet at the platform, and the detection and identification device is in communication connection with the platform function control module, and transmits the identification result to the platform function control module, so that the platform function control module can further confirm or adjust the functional mode of the platform according to the identification result.

[0084] The present invention forwards the generated auxiliary material outbound task to the warehouse control system, realizing the effective docking and collaborative work between the two different functional modules of the warehouse management system and the warehouse control system. The warehouse control system directs the four-way shuttle vehicle to go to the designated cargo location assigned by the warehouse management system, and can quickly and accurately locate the target cargo location in the huge and complex storage shelf space, and accurately grab the cigarette auxiliary material pallet. The reciprocating elevator in the outbound area descends to the cargo release platform in the outbound area, so that the goods can smoothly transition from the transportation plane of the four-way shuttle vehicle to the plane height suitable for forklift AGV operation, realizing the orderly connection between different handling equipment and different logistics links, ensuring the seamless docking of the entire outbound process, reducing the stagnation time of goods in the transit process, and speeding up the outbound speed.

[0085] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
