Description

Technical Field

[0001] This invention relates to the field of auxiliary material logistics technology for cigarette factories, and more specifically, to a method and system for returning bulk cigarette auxiliary materials to the warehouse. Background Technology

[0002] Currently, there are several ways to return the auxiliary material trays used in tobacco industry packaging workshops to the auxiliary material balance warehouse. One way is to manually use a forklift to move the auxiliary material trays back to the auxiliary material balance warehouse, and then manually return them to the primary auxiliary material warehouse. Another way is to use an AGV to retrieve the auxiliary material trays from the packaging machine to the auxiliary material balance warehouse, and then manually return them to the primary auxiliary material warehouse.

[0003] Whether using manual forklift handling or AGV transport, there's always a step where manual return to the primary auxiliary material warehouse is required. This makes the entire return process cumbersome, adding unnecessary intermediate steps and wasting considerable time. The coordination between manual and AGV operations is prone to problems. For example, after the AGV delivers the loose auxiliary materials to the auxiliary material balance warehouse, it needs to wait for manual processing. If the manual response is not timely, time is wasted. Both methods rely heavily on human intervention, especially manual forklift handling, which requires multiple manual forklift operations, resulting in high labor intensity. The overall return process is not fully automated, making it impossible to build a coherent and efficient automated return system. Summary of the Invention

[0004] One objective of this invention is to provide a method and system for returning cigarette auxiliary materials to the warehouse in bulk, in order to solve the problems mentioned above, such as the lack of full automation in the overall return process and the inability to build a coherent and efficient automated return system.

[0005] According to a first aspect of the present invention, a method for returning cigarette auxiliary materials to a bulk warehouse is provided, comprising a step of returning cigarette auxiliary materials from a cigarette packaging machine to an auxiliary material balance warehouse, and a step of returning cigarette auxiliary materials from the auxiliary material balance warehouse to a primary auxiliary material warehouse; wherein:

[0006] In the step of returning cigarette auxiliary materials from the cigarette packaging machine to the auxiliary material balance warehouse:

[0007] Enter the details of the remaining auxiliary materials on the pallet into the material request terminal and initiate a material return application;

[0008] The warehouse management system generates a task to return loose pallets to the warehouse based on the material return application and forwards it to the warehouse control system. The warehouse control system dispatches forklift AGVs to the corresponding rolling and packaging unit to pick up the loose pallets of auxiliary materials and send them to the auxiliary material balance warehouse return station.

[0009] The warehouse control system dispatches a four-way shuttle to the return station to retrieve auxiliary material trays. The four-way shuttle carries the auxiliary material trays to the designated shelf level via the reciprocating elevator in the outbound area, and then sends the trays to the designated storage location assigned by the warehouse management system along the track.

[0010] In the process of returning cigarette auxiliary materials from the auxiliary material balance warehouse to the primary auxiliary material warehouse:

[0011] During the off-peak hours of the palletizing process, the warehouse management system generates tasks for issuing loose pallets of auxiliary materials.

[0012] The warehouse control system retrieves the designated auxiliary material trays, which are then transported to the unloading platform of the auxiliary material balance warehouse via the conveyor system, and then transported to the outbound platform of the primary auxiliary material warehouse via the auxiliary material conveyor corridor.

[0013] The AGV transports the loose auxiliary materials to the auxiliary material distribution area, checks the remaining auxiliary materials, reassembles the loose auxiliary materials into complete auxiliary material pallets, and binds the information.

[0014] The dispatching AGV will deliver the auxiliary material pallets to the pallet distribution and storage area or the auxiliary material balance warehouse.

[0015] Optionally, the task of returning the bulk material trays to the warehouse includes the machine number in the packaging workshop and the location information of the bulk material trays.

[0016] Optionally, in the step of the warehouse control system dispatching the forklift AGV to the corresponding rolling and packaging unit to pick up the auxiliary material trays and deliver them to the auxiliary material balance warehouse return station, before the forklift AGV goes to the corresponding rolling and packaging unit to pick up the auxiliary material trays according to the preset planned route and delivers them to the auxiliary material balance warehouse return station, the forklift AGV applies to the warehouse control system for release, and after the warehouse control system confirms, it places the auxiliary material trays on the return station.

[0017] Optionally, after the auxiliary material trays enter the return station, they are conveyed to the inspection station via a conveyor line. If the inspection is passed, the electrical control system sends a confirmation signal, the warehouse management system updates the tray information and assigns temporary storage positions to the trays on the auxiliary material balance warehouse shelves, and the warehouse management system sends the generated auxiliary material tray return task to the warehouse control system, which then forwards it to the electrical control system.

[0018] Optionally, the electronic control system can be used to detect the shape and read information of the loose pallets. If an abnormality is detected, the electronic control system will control the conveyor line to reverse and return the loose pallets to the return station, and the electronic control system will issue an audible and visual alarm.

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

[0020] Optionally, after the AGV picks up the auxiliary material trays, 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 AGV. The AGV moves the auxiliary material trays to the target unloading area and applies to the warehouse management system for a specific unloading location. The warehouse management system sends the assigned unloading location to the warehouse control system, which then dispatches the AGV to move the auxiliary material trays to the target location for unloading.

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

[0022] Forklift AGVs are used to receive scheduling instructions from the warehouse control system and transport the auxiliary material trays from the wrapping machine to the auxiliary material balance warehouse return station.

[0023] The return station serves as the initial placement location for auxiliary material trays after they are returned to the warehouse from the wrapping unit, and is also used for connecting to subsequent conveyor lines.

[0024] The conveyor line is used to transport the bulk auxiliary materials from the return station to the testing station;

[0025] The inspection station is set on the conveyor line to inspect the shape of the auxiliary material trays and read information. When an abnormality is detected, the conveyor line is controlled to return the auxiliary material trays to the return station and the electrical control system is triggered to issue an audible and visual alarm.

[0026] Reciprocating elevators are used to assist in the transfer of auxiliary material trays between the four-way shuttle car and other stations;

[0027] Four-way shuttles are used to move and store auxiliary material trays between different locations on the high-density racking system, based on the location information assigned by the warehouse management system.

[0028] The auxiliary material conveying corridor is used to transport loose auxiliary materials from the loading platform of the auxiliary material balance warehouse to the unloading platform of the primary auxiliary material warehouse.

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

[0030] Optionally, the reciprocating elevator includes an outbound reciprocating elevator, an auxiliary material balance warehouse inbound reciprocating elevator, and an auxiliary material primary warehouse reciprocating elevator. The outbound reciprocating elevator is used to assist the four-way shuttle car in transporting cigarette auxiliary materials from the cigarette packaging machine to the auxiliary material balance warehouse. The auxiliary material balance warehouse inbound reciprocating elevator is used to assist the four-way shuttle car in transporting cigarette auxiliary materials from the auxiliary material balance warehouse to the auxiliary material conveying corridor. The auxiliary material primary warehouse reciprocating elevator is used to assist the four-way shuttle car in transporting cigarette auxiliary materials from the auxiliary material conveying corridor to the auxiliary material primary warehouse outbound platform.

[0031] The method and system for bulk pallet return of cigarette auxiliary materials disclosed herein have the following technical advantages:

[0032] The system enables forklift AGVs to automatically transport loose auxiliary material pallets from the wrapping unit to the auxiliary material balance warehouse for shelving, and then return them to the primary auxiliary material warehouse via a conveyor line in the auxiliary material conveying corridor. From there, they are transported and stored by submerged AGVs, achieving continuous return of loose auxiliary material pallets between the two auxiliary material warehouses. The entire process, through the coordinated work of forklift AGVs, four-way shuttles, and submerged AGVs, automates the material handling and storage between the wrapping unit and the two auxiliary material warehouses. Compared to traditional manual handling and management methods, this significantly reduces manpower and increases the speed of material turnover.

[0033] With the help of material receiving terminals, warehouse management systems, and information reading and detection devices at each stage, comprehensive, accurate recording and real-time updating of auxiliary material bulk information are achieved.

[0034] It can flexibly adjust the return path and storage location of materials according to the production plan and actual production situation. For example, during idle periods, the bulk auxiliary materials can be retrieved from the auxiliary material balance warehouse to the primary auxiliary material warehouse for recombination and reorganization to meet the needs of different subsequent production orders.

[0035] Other features and advantages of the invention will become clear from the following detailed description of exemplary embodiments of the invention with reference to the accompanying drawings. Attached Figure Description

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

[0037] Figure 1 This is a flowchart illustrating the method for returning cigarette auxiliary materials to the warehouse according to an embodiment of the present invention. Detailed Implementation

[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, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention.

[0039] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0040] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0041] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0042] This invention proposes an embodiment of a method for returning cigarette auxiliary materials to warehouse in bulk, specifically, as follows: Figure 1 As shown, this includes the steps of returning cigarette auxiliary materials from the cigarette packaging machine to the auxiliary material balance warehouse, and the steps of returning cigarette auxiliary materials from the auxiliary material balance warehouse to the primary auxiliary material warehouse; wherein:

[0043] In the step of returning cigarette auxiliary materials from the cigarette packaging machine to the auxiliary material balance warehouse:

[0044] The remaining auxiliary materials on the pallet are entered into the material request terminal and a return application is initiated, avoiding problems such as writing errors, information omissions, or untimely transmission that occur with traditional manual recording methods.

[0045] The warehouse management system generates a loose pallet return task based on the material return request and forwards it to the warehouse control system. The warehouse control system dispatches a forklift AGV to the corresponding rolling and packaging unit to pick up the loose pallets of auxiliary materials and deliver them to the auxiliary material balance warehouse return station. The warehouse management system automatically generates a loose pallet return task based on the material return request. The forklift AGV can automatically go to the corresponding rolling and packaging unit according to the preset path without manual driving, reducing labor costs.

[0046] The warehouse control system dispatches a four-way shuttle to the return station to retrieve auxiliary material trays. The four-way shuttle carrying the auxiliary material trays is lifted to the designated shelf level by the reciprocating elevator in the outbound area, and then the trays are delivered to the designated storage location assigned by the warehouse management system along the track. The warehouse management system comprehensively considers various factors such as material classification, inbound and outbound frequency, and shelf load-bearing capacity to allocate storage locations, making the material management in the warehouse more scientific and orderly, and facilitating the rapid retrieval and use of auxiliary material trays in the future.

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

[0048] During the off-peak hours of the palletizing process, the warehouse management system generates outbound tasks for auxiliary materials in bulk. Based on a comprehensive understanding of the overall auxiliary material inventory, production plan, and the status of each stage, the warehouse management system accurately generates outbound tasks for auxiliary materials in bulk.

[0049] The warehouse control system retrieves designated auxiliary material trays, which are then transported via a conveyor system to the unloading platform of the auxiliary material balance warehouse. From there, they are transported via a connecting corridor to the outbound platform of the primary auxiliary material warehouse. This complete logistics transportation system, including the conveyor system and the connecting corridor, enables automated and continuous transportation of trays between different warehouse areas, improving transportation speed and efficiency.

[0050] The AGV (Automated Guided Vehicle) transports loose auxiliary materials to the auxiliary material distribution area, verifies the remaining quantity of auxiliary materials, reassembles the loose auxiliary materials into complete auxiliary material pallets, and binds the information. This information binding improves the informatization level of auxiliary material management, associating auxiliary material pallets with corresponding auxiliary material information (such as type, quantity, source, quality, etc.). This allows for quick access to detailed information about the pallets and their contained auxiliary materials at any stage of the entire auxiliary material flow and use process, facilitating refined inventory management and quality traceability.

[0051] The dispatching AGV will deliver the auxiliary material pallets to the pallet distribution and storage area or the auxiliary material balance warehouse.

[0052] In this embodiment of the invention, the task of returning loose material trays to the warehouse includes the machine number in the packaging workshop and the location information of the loose material trays. Accurate machine number and location information allow the packaging workshop to accurately hand over the loose material trays, while the warehouse can also prepare to receive them in advance, achieving a close connection between the two links. Warehouse management personnel can distinguish loose material trays from different sources based on the machine number and accurately register and update the inventory according to their original categories and specifications.

[0053] In this embodiment of the invention, during the step of the warehouse control system scheduling forklift AGVs to pick up loose pallets of auxiliary materials from the corresponding wrapping unit and deliver them to the return station of the auxiliary material balance warehouse, before the forklift AGVs proceed to the corresponding wrapping unit according to the preset planned path to pick up the loose pallets of auxiliary materials and deliver them to the return station of the auxiliary material balance warehouse, the forklift AGVs request the warehouse control system to release the goods. After confirmation by the warehouse control system, the loose pallets of auxiliary materials are placed on the return station. The goods release request mechanism strengthens the coordination and interaction between the forklift AGVs and the warehouse control system. The warehouse control system can monitor the operation progress of each forklift AGV in real time, as well as the current available space and storage status of the return station. The entire process, through the scheduling of the warehouse control system and the control of the goods release request, achieves the rational allocation and effective monitoring of the forklift AGV, an important logistics resource, and the space resources of the return station.

[0054] In this embodiment of the invention, after the auxiliary material trays enter the return station, they are conveyed to the inspection station via a conveyor line. If the inspection is passed, the electronic control system sends a confirmation signal, the warehouse management system updates the tray information and assigns temporary storage positions to the trays on the auxiliary material balance warehouse shelves, and the warehouse management system sends the generated auxiliary material tray return task to the warehouse control system, which then forwards it to the electronic control system.

[0055] In this embodiment of the invention, the electronic control system performs shape detection and information reading on the loose pallets. If an abnormality is detected, the electronic control system controls the conveyor line to reverse, returning the loose pallets to the return station and triggering an audible and visual alarm. Shape detection utilizes high-precision sensors (such as vision sensors and laser rangefinders) to meticulously inspect the size and shape integrity of the loose pallets. By accurately measuring the length, width, and height of the loose pallets and determining whether they are damaged or deformed, it ensures that the loose pallets entering subsequent warehousing stages meet physical requirements. The information reading function, using RFID and barcode scanning technologies, can acquire key data such as identification information, material type information, and quantity information recorded on the loose pallets and compare them with existing records in the warehouse management system. This allows for the rapid separation of non-compliant loose pallets from the normal flow process, preventing them from continuing to be passed downstream and avoiding adverse effects on subsequent equipment and processes, thus achieving timely loss mitigation.

[0056] In this embodiment of the invention, the electronic control system detects the shape of the auxiliary material tray, including but not limited to detecting the size and shape integrity of the tray, and reads information including but not limited to reading the identification information, auxiliary material type information and quantity information on the tray.

[0057] In this embodiment of the invention, after a lurking AGV picks up a pallet of auxiliary materials, it requests release from the warehouse management system. The warehouse management system then informs the warehouse control system of the unloading area information. The warehouse control system issues an unloading instruction to the lurking AGV, which moves the pallet to the target unloading area and requests a specific unloading location from the warehouse management system. The warehouse management system sends the allocated unloading location to the warehouse control system, which then dispatches the lurking AGV to move the pallet to the target location for unloading. For example, when a certain unloading area is heavily stocked and nearing saturation, the warehouse management system can guide the lurking AGV to move the pallet to a relatively empty area for unloading. The warehouse control system promptly directs the lurking AGV to change its transport path, enabling real-time allocation of warehouse space and handling equipment resources, thus improving the overall warehousing and logistics capabilities to cope with changes.

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

[0059] The process of returning cigarette auxiliary materials from the cigarette packaging machine to the auxiliary material balance warehouse:

[0060] The machine operators in the packaging workshop write the details of the remaining auxiliary materials in the pallet into the system through the material request terminal and initiate a material return application.

[0061] The warehouse management system generates a task to return loose pallets to the warehouse control system. The warehouse control system sends the task (including information such as the machine number in the wrapping workshop and the location of the loose pallets) to the forklift AGV system. The forklift AGV is then dispatched to the corresponding wrapping machine according to the preset planned path, picks up the loose pallets, and delivers them to the return station of the loose pallet balance warehouse. The forklift AGV then requests the warehouse control system to release the goods. After the system confirms, the forklift AGV places the loose pallets on the return station.

[0062] The auxiliary material trays enter the return station and are conveyed to the inspection station via a conveyor line. The electronic control system performs shape inspection and information reading on the trays. For trays with abnormalities, the electronic control system controls the conveyor line to reverse, returning the tray to the return station. The system issues an audible and visual alarm, and the operator takes position to handle the situation. For trays that pass inspection, the electronic control system sends a confirmation signal, the warehouse management system updates the tray information, and assigns a temporary storage location to the auxiliary material balance warehouse shelf. The warehouse management system sends the generated auxiliary material tray return task to the warehouse control system, which then forwards it to the electronic control system.

[0063] The warehouse control system dispatches a four-way shuttle to the picking station to retrieve loose auxiliary materials. The loose auxiliary materials are transported to the picking station via a conveyor system. After the electronic control system detects the arrival signal at the picking station, the four-way shuttle, carrying the loose auxiliary materials, is lifted to the designated shelf level via a reciprocating elevator in the outbound area. Upon detecting the arrival signal again, the electronic control system moves the four-way shuttle along the track, delivering the loose materials to the designated storage location assigned by the warehouse management system.

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

[0065] During off-peak periods for palletizing, the warehouse management system generates outbound tasks for auxiliary materials (including location number, pallet number, etc.). The warehouse control system dispatches a four-way shuttle to the target location in the auxiliary material balance warehouse to retrieve the auxiliary material pallets. The pallets are then transported via the four-way shuttle track to the reciprocating elevator in the auxiliary material balance warehouse's inbound area, and finally moved by the elevator to the discharge platform of the auxiliary material balance warehouse.

[0066] The electrical control system detects the arrival signal of goods at the unloading platform of the auxiliary material balance warehouse and controls the conveyor line of the auxiliary material conveying corridor to move in the reverse direction. The loose auxiliary materials are conveyed to the reciprocating elevator of the primary auxiliary material warehouse via the conveyor line of the auxiliary material conveying corridor. After the electrical control system detects the arrival signal, the elevator descends to the unloading platform of the primary auxiliary material warehouse. The pallet transfer machine then transports the materials to the outbound platform via the conveyor line.

[0067] The electronic control system detects the arrival signal of the delivery platform in the primary auxiliary material warehouse and sends a request to the warehouse control system. The warehouse control system then issues an instruction to the AGV system to dispatch the AGV to the pallet transfer machine at the delivery platform to retrieve the goods.

[0068] After picking up the goods, the AGV system requests release from the warehouse management system. The warehouse management system informs the warehouse control system of the unloading area information. The warehouse control system issues an unloading instruction to the AGV system. The AGV system moves the auxiliary material trays to the target unloading area (i.e., the auxiliary material tray area) and requests a specific unloading location from the warehouse management system. The warehouse management system sends the assigned unloading location to the warehouse control system and dispatches the AGV system to move the auxiliary material trays to the target location for unloading.

[0069] The operator checks the remaining quantity of auxiliary materials on the loose trays, reassembles the loose trays into complete auxiliary material pallets, and binds the auxiliary material information to the pallet information.

[0070] Based on production needs, the warehouse management system issues tasks to the warehouse control system, which then dispatches AGVs to deliver auxiliary material pallets to the palletizing and storage area or directly to the receiving platform, and then transports them to the auxiliary material balance warehouse via the auxiliary material conveyor corridor.

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

[0072] Forklift AGVs are used to receive scheduling instructions from the warehouse control system and transport the auxiliary material trays from the wrapping machine to the auxiliary material balance warehouse return station.

[0073] The return station serves as the initial placement location for auxiliary material trays after they are returned to the warehouse from the wrapping unit, and is also used for connecting to subsequent conveyor lines.

[0074] The conveyor line is used to transport the bulk auxiliary materials from the return station to the testing station;

[0075] The inspection station is set on the conveyor line to inspect the shape of the auxiliary material trays and read the information. When an abnormality is detected, the conveyor line is controlled to return the auxiliary material trays to the return station and trigger the electrical control system to issue an audible and visual alarm.

[0076] Reciprocating elevators are used to assist in the transfer of auxiliary material trays between the four-way shuttle car and other stations;

[0077] Four-way shuttles are used to move and store auxiliary material trays between different locations on the high-density racking system, based on the location information assigned by the warehouse management system.

[0078] The auxiliary material conveying corridor is used to transport loose auxiliary materials from the loading platform of the auxiliary material balance warehouse to the unloading platform of the primary auxiliary material warehouse.

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

[0080] In this embodiment of the invention, the reciprocating elevator includes an outbound reciprocating elevator, an auxiliary material balance warehouse inbound reciprocating elevator, and an auxiliary material primary warehouse reciprocating elevator. The outbound reciprocating elevator is used to assist the four-way shuttle car in transporting cigarette auxiliary materials from the cigarette packaging machine to the auxiliary material balance warehouse. The auxiliary material balance warehouse inbound reciprocating elevator is used to assist the four-way shuttle car in transporting cigarette auxiliary materials from the auxiliary material balance warehouse to the auxiliary material conveying corridor. The auxiliary material primary warehouse reciprocating elevator is used to assist the four-way shuttle car in transporting cigarette auxiliary materials from the auxiliary material conveying corridor to the auxiliary material primary warehouse outbound platform.

[0081] This invention utilizes automated material handling equipment such as forklift AGVs and stealth AGVs to automate the transfer of loose auxiliary material pallets between different areas, from the packaging unit to the auxiliary material balance warehouse and then to the primary auxiliary material warehouse, based on scheduling instructions. This reduces manual handling workload and improves the efficiency and accuracy of material transfer. The warehouse management system can allocate different storage location information of the high-density shelving to the four-way shuttle vehicles, enabling the precise handling and storage of loose auxiliary material pallets at different locations on the shelving. It can also perform shape detection and information reading on the loose auxiliary material pallets, promptly identifying any anomalies.

However, the above are only preferred embodiments 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 by those skilled in the art to form a variety of equivalent solutions without departing from or changing the design concept and technical effects of the present invention. Therefore, the present invention is not limited to the scope of implementation shown in the figures.
