Description

Technical Field

[0001] The present invention relates to the technical field of cigarette factory auxiliary material logistics, and more specifically, to a method and system for returning cigarette auxiliary material bulk trays to a warehouse. Background Art

[0002] At present, there are many ways to return the auxiliary material trays used in the machines in the rolling and packaging workshop of the tobacco industry to the auxiliary material balance warehouse. One is to manually transport the auxiliary material trays with a forklift, return them to the auxiliary material balance warehouse, and then manually return them to the auxiliary material primary warehouse; another is to use AGV to retrieve the auxiliary material trays from the rolling and packaging unit to the auxiliary material balance warehouse, and then manually return them to the auxiliary material primary warehouse.

[0003] Whether it is manual forklift handling or AGV transportation, there is a step that requires manual return to the primary warehouse of auxiliary materials, which makes the entire return process cumbersome, adds unnecessary intermediate links, and consumes a lot of time. The connection between manual operation and AGV operation is prone to problems. For example, after the AGV delivers the auxiliary material tray to the auxiliary material balance warehouse, it needs to wait for manual processing. If the manual response fails to be timely, it will cause a waste of time. Both methods are inseparable from manual participation, especially the manual forklift handling method, which requires manual driving of the forklift for multiple handlings throughout the process, and the labor intensity is high. The overall return process has not been fully automated, and it is impossible to build a coherent and efficient automated return system. Summary of the invention

[0004] One object of the present invention is to provide a method and system for returning bulk trays of cigarette auxiliary materials to a warehouse, so as to solve the problems that the aforementioned overall return process is not fully automated and a coherent and efficient automated return system cannot be built.

The forklift AGV applies to the warehouse control system for release of the goods, and after confirmation by the warehouse control system, the auxiliary material pallet is placed on the return platform.

[0017] Optionally, after the auxiliary material bulk pallet enters the return platform, it is transported to the inspection station via the conveyor line. If the inspection passes, the electronic control system sends a confirmation signal, the warehouse management system updates the bulk pallet information and allocates a temporary storage location for the bulk pallet on the auxiliary material balance warehouse shelf, and the warehouse management system sends the generated auxiliary material bulk pallet return task to the warehouse control system, which forwards it to the electronic control system.

[0018] Optionally, the electronic control system performs appearance inspection and information reading on the bulk tray. If the inspection is abnormal, the electronic control system controls the conveyor line to reverse and return the bulk tray to the return platform and causes the electronic control system to issue an audible and visual alarm.

[0019] Optionally, the electronic control system detects the appearance of the auxiliary material tray, including but not limited to the size and shape integrity of the tray, and the information read includes but is not limited to reading the identification information, auxiliary material type information and quantity information on the tray.

[0020] Optionally, after the latent AGV moves the auxiliary material pallet, it applies to the warehouse management system for release. The warehouse management system informs the warehouse control system of the unloading area information. The warehouse control system issues an unloading instruction to the latent AG. The latent AGV moves the auxiliary material pallet to the target unloading area and applies to the warehouse management system for a specific unloading location. The warehouse management system sends the allocated unloading location to the warehouse control system and dispatches the latent AGV to move the auxiliary material pallet to the target location for unloading.

[0021] According to a second aspect of the present invention, there is provided a cigarette auxiliary material bulk tray return system, comprising:

[0022] Forklift AGV, used to receive the dispatching instructions from the warehouse control system and transport the auxiliary material trays from the wrapping unit to the auxiliary material balance warehouse return platform;

[0023] The return platform is used as the initial placement location for the auxiliary material trays after they are returned from the wrapping unit, and is used for the connection of subsequent conveyor lines;

[0024] The conveyor line is used to transport the bulk trays of auxiliary materials from the return platform to the inspection station;

[0025] The detection station is arranged on the conveyor line, and is used to detect the appearance and read the information of the auxiliary material tray. When an abnormality is detected, the conveyor line is controlled to return the auxiliary material tray to the return station, and the electronic control system is triggered to issue an audible and visual alarm prompt;

[0026] Reciprocating elevator is used to assist in the transfer of auxiliary material trays between the four-way shuttle and other platforms;

[0027] The four-way shuttle is used to transport and store the auxiliary material trays between different cargo locations of the intensive rack according to the location information assigned by the warehouse management system;

[0028] The auxiliary material conveying corridor is used to convey the auxiliary material bulk trays from the loading platform of the auxiliary material balance warehouse to the outbound platform of the auxiliary material primary warehouse;

[0029] The latent AGV is used to transport the auxiliary material pallets from the outbound platform of the auxiliary material primary warehouse to the auxiliary material distribution area, and to transport the auxiliary material pallets that have been re-matched and information-bound in the auxiliary material distribution area to the distribution pallet storage area or the auxiliary material balance warehouse.

[0030] Optionally, the reciprocating elevator includes a reciprocating elevator in the outbound storage area, a reciprocating elevator in the auxiliary material balance storage inlet area and a reciprocating elevator in the auxiliary material first-level storage area. The reciprocating elevator in the outbound storage area is used to assist the four-way shuttle vehicle to transport cigarette auxiliary materials from the rolling and packaging unit to the auxiliary material balance storage, the reciprocating elevator in the auxiliary material balance storage inlet area is used to assist the four-way shuttle vehicle to transport cigarette auxiliary materials from the auxiliary material balance storage to the auxiliary material conveying corridor, and the reciprocating elevator in the auxiliary material first-level storage area is used to assist the four-way shuttle vehicle to transport cigarette auxiliary materials from the auxiliary material conveying corridor to the outbound storage platform of the auxiliary material first-level storage.

[0031] The method and system for returning the bulk trays of cigarette auxiliary materials disclosed in the present invention have the following technical effects:

[0032] The forklift AGV automatically transports the auxiliary material trays from the wrapping unit to the auxiliary material balance warehouse, and then returns them to the auxiliary material first-level warehouse through the conveyor line of the auxiliary material conveying corridor. The latent AGV transports and stores them, realizing the continuous return of the auxiliary material trays to the two-level auxiliary material warehouse. The entire process realizes the automated operation of material handling and storage from the wrapping unit to the two-level auxiliary material warehouse through the coordinated work of automated equipment such as forklift AGV, four-way shuttle, and latent AGV. Compared with traditional manual handling and management methods, it greatly reduces manpower input and improves the speed of material circulation.

[0033] With the help of material request terminals, warehouse management systems and information reading and detection devices in each link, comprehensive and accurate recording and real-time updating of auxiliary material bulk information can be achieved.

[0034] The material return path and storage location can be flexibly adjusted according to the production plan and actual production situation. For example, during idle periods, the auxiliary material trays can be recovered from the auxiliary material balance warehouse to the auxiliary material primary warehouse for re-matching and sorting to meet the needs of subsequent different production orders.

[0035] Further features and advantages of the present invention will become apparent from the following detailed description of exemplary embodiments of the present invention with reference to the attached drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

[0037] Figure 1 A schematic diagram of the process of returning the cigarette auxiliary material bulk trays to the warehouse provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] The present invention proposes an embodiment of a method for returning cigarette auxiliary materials to a storage bin. Specifically, Figure 1 As shown, it includes the steps of returning cigarette auxiliary materials from the packing unit to the auxiliary materials balance warehouse, and the step of returning cigarette auxiliary materials from the auxiliary materials balance warehouse to the auxiliary materials primary warehouse; wherein:

[0043] In the step of returning cigarette auxiliary materials from the packing unit to the auxiliary materials balance warehouse:

[0044] Enter the details of the remaining auxiliary materials on the pallet into the material request terminal and initiate a material return application; avoid problems such as writing errors, information omissions or untimely delivery that occur in traditional manual recording methods.

[0045] The warehouse management system generates a task for returning the bulk pallets to the warehouse based on the material return application and forwards it to the warehouse control system. The warehouse control system dispatches the forklift AGV to go to the corresponding wrapping unit to pick up the bulk pallets of auxiliary materials and send them to the auxiliary material balance warehouse return platform. The warehouse management system automatically generates a task for returning the bulk pallets to the warehouse based on the material return application. The forklift AGV can automatically go to the corresponding wrapping unit according to the preset path, without the need for manual driving, thus reducing labor costs.

[0046] The warehouse control system dispatches a four-way shuttle vehicle to go to the return platform to pick up the auxiliary material pallets. The four-way shuttle vehicle carries the auxiliary material pallets and rises to the designated shelf layer via the reciprocating elevator in the outbound area. The pallets are then sent along the track to the designated storage location allocated by the warehouse management system for storage. The warehouse management system allocates storage locations based on a comprehensive consideration of factors such as material classification, frequency of entry and exit, shelf load-bearing capacity, etc., making material management in the warehouse more scientific and orderly, and facilitating the subsequent quick search and retrieval of auxiliary material pallets.

[0047] In the step of returning cigarette auxiliary materials from the auxiliary materials balance warehouse to the auxiliary materials primary warehouse:

[0048] During the idle period of distribution, the warehouse management system generates the task of sending out the auxiliary materials in bulk. Based on the comprehensive grasp of the overall auxiliary materials inventory situation, production plan and the status of each link, the warehouse management system accurately generates the task of sending out the auxiliary materials in bulk.

[0049] The warehouse control system calls out the designated auxiliary material bulk pallets, which are sent to the discharge platform of the auxiliary material balance warehouse via the conveying system, and then transported to the outbound platform of the auxiliary material primary warehouse via the auxiliary material conveying corridor; with the help of the conveying system and the auxiliary material conveying corridor, a complete set of logistics and transportation facilities, the automated and continuous transportation of bulk pallets between different warehouse areas is realized, thereby improving the transportation speed and efficiency.

[0050] The latent AGV transports the auxiliary material trays to the auxiliary material matching area, verifies the remaining auxiliary material quantity, re-matches the auxiliary material trays into complete auxiliary material pallets and binds the information; information binding improves the informatization level of auxiliary material management, and associates the auxiliary material pallets with the corresponding auxiliary material information (such as type, quantity, source, quality, etc.), so that in the entire auxiliary material circulation and use process, any link can quickly understand the details of the pallet and the auxiliary materials it contains by querying the information, which is conducive to the realization of refined inventory management and quality traceability.

[0051] Dispatch the latent AGV to deliver the auxiliary material pallet to the pallet storage area or auxiliary material balance warehouse.

[0052] In the embodiment of the present invention, the task of returning the bulk tray to the warehouse includes the machine number of the wrapping workshop and the location information of the bulk tray of auxiliary materials. The accurate machine number and location information of the bulk tray can enable the wrapping workshop to accurately hand over the bulk tray, and the warehouse can also make preparations for receiving in advance, so as to achieve a close connection between the two links. The warehouse management personnel can distinguish the bulk trays of auxiliary materials from different sources according to the machine number, and accurately register them and update the inventory according to their original corresponding categories and specifications.

[0053] In an embodiment of the present invention, in the step where the warehouse control system dispatches the forklift AGV to go to the corresponding wrapping unit to fork up the auxiliary material tray and deliver it to the auxiliary material balance warehouse return platform, before the forklift AGV goes to the corresponding wrapping unit according to the preset planned path to fork up the auxiliary material tray and deliver it to the auxiliary material balance warehouse return platform, the forklift AGV applies to the warehouse control system for releasing the goods, and after confirmation by the warehouse control system, the auxiliary material tray is placed on the return platform. The release application mechanism strengthens the coordination and interaction between the forklift AGV and the warehouse control system. The warehouse control system can grasp the operation progress of each forklift AGV and the current available space, storage status and other information of the return platform in real time. The entire process realizes the reasonable allocation and effective monitoring of the forklift AGV, an important logistics resource, and the space resources of the return platform through the dispatch of the warehouse control system and the control of the release application.

[0054] In an embodiment of the present invention, after the auxiliary material bulk pallet enters the return platform, it is transported to the inspection station via the conveyor line. If the inspection passes, the electronic control system sends a confirmation signal, the warehouse management system updates the bulk pallet information and allocates a temporary storage location for the bulk pallet on the auxiliary material balance warehouse shelf, and the warehouse management system sends the generated auxiliary material bulk pallet return task to the warehouse control system, which forwards it to the electronic control system.

[0055] In the embodiment of the present invention, the appearance detection and information reading of the bulk tray are performed by the electric control system. If the detection is abnormal, the electric control system controls the conveyor line to reverse and return the bulk tray to the return platform and makes the electric control system send out an audible and visual alarm prompt. The appearance detection can use high-precision sensors (such as visual sensors, laser ranging sensors, etc.) to carefully check the size, shape integrity, etc. of the auxiliary material bulk tray. By accurately measuring the length, width, and height of the auxiliary material bulk tray and judging whether it is damaged or deformed, it is ensured that the auxiliary material bulk tray entering the subsequent storage link meets the requirements in terms of physical form. The information reading function can obtain key data such as identification information, auxiliary material type information, quantity information, etc. recorded on the bulk tray by means of radio frequency identification (RFID) technology, barcode scanning technology, etc., and compare it with the existing records in the warehouse management system. The bulk tray that does not meet the requirements can be quickly separated from the normal circulation process to prevent it from continuing to be transmitted to the downstream link, prevent adverse effects on more subsequent equipment and processes, and achieve timely stop loss.

[0056] In an embodiment of the present invention, the electronic control system detects the appearance information of the auxiliary material bulk tray, including but not limited to the size and shape integrity of the bulk tray, and the information read is not limited to reading the identification information, auxiliary material type information and quantity information on the bulk tray.

[0057] In an embodiment of the present invention, after the latent AGV takes the auxiliary material tray, it applies to the warehouse management system for releasing the goods. The warehouse management system informs the warehouse control system of the unloading area information. The warehouse control system issues an unloading instruction to the latent AG. The latent AGV moves the auxiliary material tray to the target unloading area and applies to the warehouse management system for a specific unloading location. The warehouse management system sends the allocated unloading location to the warehouse control system and dispatches the latent AGV to move the auxiliary material tray to the target location for unloading. For example, when a certain unloading area has a lot of goods piled up and is close to saturation, the warehouse management system can guide the latent AGV to send the auxiliary material tray to other relatively free areas for unloading. The warehouse control system promptly directs the latent AGV to change the transportation route, realizes the real-time allocation of resources such as warehouse space and handling equipment, and improves the ability of the entire warehousing and logistics link to respond to changes.

[0058] The present invention also provides another embodiment of a method for returning cigarette auxiliary material bulk trays to a warehouse, such as Figure 1 As shown, the specific process includes the following:

[0059] The process of returning cigarette auxiliary materials from the packing unit to the auxiliary materials balance warehouse:

[0060] The machine operator in the wrapping workshop writes the details of the remaining auxiliary materials in the tray into the system through the material request terminal and initiates a material return application.

[0061] The warehouse management system generates a task of returning the bulk pallet to the warehouse control system. The warehouse control system sends the task to the forklift AGV system (including the machine number of the wrapping workshop, the location of the auxiliary material bulk pallet, etc.), dispatches the forklift AGV to the corresponding wrapping unit according to the preset planned path, picks up the auxiliary material bulk pallet, and delivers it to the auxiliary material balance warehouse return platform. It applies to the warehouse control system for releasing the goods. After the system confirms, the forklift AGV puts the auxiliary material bulk pallet on the return platform.

[0062] The auxiliary material pallets enter the return station and are transported to the inspection station via the conveyor line. The electronic control system inspects the appearance of the pallets and reads their information. If an abnormal pallet is detected, the electronic control system controls the conveyor line to reverse and return the pallet to the return station. The system issues an audible and visual alarm prompt and the operator takes up the position for processing. For pallets that pass the inspection, the electronic control system sends a confirmation signal, the warehouse management system updates the pallet information, and allocates a temporary storage location for the pallet on the shelf of the auxiliary material balance warehouse. The warehouse management system sends the generated auxiliary material pallet return task to the warehouse control system, which forwards it to the electronic control system.

[0063] The warehouse control system dispatches a four-way shuttle to the pickup station to pick up the auxiliary material pallets. The auxiliary material pallets are sent to the four-way shuttle pickup station through the conveying system. After the electronic control system detects the arrival signal of the pickup station, the four-way shuttle carries the auxiliary material pallets and rises to the designated shelf layer through the reciprocating elevator in the outbound area. After the electronic control system detects the arrival signal, the four-way shuttle moves along the track and delivers the pallets to the designated storage location allocated by the warehouse management system.

[0064] The process of returning cigarette auxiliary materials from the auxiliary materials balance warehouse to the auxiliary materials primary warehouse:

[0065] During the idle time of the distribution pallet, the warehouse management system generates the task of outbound delivery of auxiliary material pallets (including information such as the cargo location number and pallet number). The warehouse control system dispatches the four-way shuttle to the target cargo location of the auxiliary material balance warehouse to pick up the auxiliary material pallets, which are transported to the reciprocating elevator in the auxiliary material balance warehouse through the four-way shuttle track and then transported to the delivery platform of the auxiliary material balance warehouse through the elevator.

[0066] The electronic control system detects the arrival signal of the goods at the delivery platform of the auxiliary material balance warehouse, controls the conveyor line of the auxiliary material conveying corridor to move in the opposite direction, and the auxiliary material trays are transported to the reciprocating elevator of the auxiliary material primary warehouse through the conveyor line of the auxiliary material conveying corridor. After the electronic control system detects the arrival signal, the elevator descends to the delivery platform of the auxiliary material primary warehouse. The goods are transported to the pallet transfer machine of the delivery platform through the conveyor line.

[0067] The electronic control system detects the arrival signal of the delivery platform of the auxiliary material primary warehouse and sends an application to the warehouse control system. The warehouse control system issues instructions to the latent AGV system to dispatch the latent AGV to the pallet transfer machine at the delivery platform to pick up the goods.

[0068] After picking up the goods, the latent AGV system applies to the warehouse management system for releasing the goods. The warehouse management system informs the warehouse control system of the unloading area information. The warehouse control system issues an unloading instruction to the latent AGV system. The latent AGV moves the auxiliary material pallets to the target unloading area (i.e. the auxiliary material pallet distribution area) and applies to the warehouse management system for a specific unloading location. The warehouse management system sends the allocated unloading location to the warehouse control system and dispatches the latent AGV to move the auxiliary material pallets to the target location for unloading.

[0069] The operator checks the remaining amount of auxiliary materials on the auxiliary material tray, re-assembles the tray into a complete auxiliary material pallet, and binds the auxiliary material information with the pallet information.

[0070] According to the needs of production tasks, the warehouse management system issues tasks to the warehouse control system, dispatches the latent AGV to deliver the auxiliary material pallets to the temporary storage area for the distribution pallets or directly to the storage platform, and transports them to the auxiliary material balance warehouse for storage through the auxiliary material conveying corridor.

[0071] The present invention also provides an embodiment of a cigarette auxiliary material bulk tray storage system, comprising:

[0072] Forklift AGV, used to receive the dispatching instructions from the warehouse control system and transport the auxiliary material trays from the wrapping unit to the auxiliary material balance warehouse return platform;

[0073] The return platform is used as the initial placement location for the auxiliary material trays after they are returned from the wrapping unit, and is used for the connection of subsequent conveyor lines;

[0074] The conveyor line is used to transport the bulk trays of auxiliary materials from the return platform to the inspection station;

[0075] The inspection station is set on the conveyor line to inspect the appearance and read the information of the auxiliary material tray. When the inspection is abnormal, the conveyor line is controlled to return the auxiliary material tray to the return platform, and the electronic control system is triggered to issue an audible and visual alarm prompt;

[0076] Reciprocating elevator is used to assist in the transfer of auxiliary material trays between the four-way shuttle and other platforms;

[0077] The four-way shuttle is used to transport and store the auxiliary material trays between different cargo locations of the intensive rack according to the location information assigned by the warehouse management system;

[0078] The auxiliary material conveying corridor is used to convey the auxiliary material bulk trays from the loading platform of the auxiliary material balance warehouse to the outbound platform of the auxiliary material primary warehouse;

[0079] The latent AGV is used to transport the auxiliary material pallets from the outbound platform of the auxiliary material primary warehouse to the auxiliary material distribution area, and to transport the auxiliary material pallets that have been re-matched and information-bound in the auxiliary material distribution area to the distribution pallet storage area or the auxiliary material balance warehouse.

[0080] In an embodiment of the present invention, the reciprocating elevator includes a reciprocating elevator in the outbound storage area, a reciprocating elevator in the auxiliary material balance storage inlet area, and a reciprocating elevator in the auxiliary material first-level storage area. The reciprocating elevator in the outbound storage area is used to assist the four-way shuttle car to transport cigarette auxiliary materials from the rolling and packaging unit to the auxiliary material balance storage, the reciprocating elevator in the auxiliary material balance storage inlet area is used to assist the four-way shuttle car to transport cigarette auxiliary materials from the auxiliary material balance storage to the auxiliary material conveying corridor, and the reciprocating elevator in the auxiliary material first-level storage area is used to assist the four-way shuttle car to transport cigarette auxiliary materials from the auxiliary material conveying corridor to the outbound platform of the auxiliary material first-level storage.

[0081] The embodiment of the present invention uses automated handling equipment such as forklift AGV and lurking AGV to realize the automated handling and circulation of auxiliary material trays between different areas such as the wrapping unit, the auxiliary material balance warehouse, and then the auxiliary material primary warehouse according to the dispatching instructions, thereby reducing the workload of manual handling and improving the efficiency and accuracy of material transfer. The warehouse management system can allocate different cargo location information of intensive shelves to the four-way shuttle vehicle, so that the auxiliary material trays can be accurately handled and stored at different locations on the shelves. The appearance of the auxiliary material trays can be detected and information can be read to detect abnormal conditions in time.
