Description

Technical Field

[0001] The present invention relates to the field of pallet storage technology in cigarette production, and more specifically, to a method and system for stacking finished cigarette pallets for storage and retrieval. Background Art

[0002] Finished product warehouses play a key role in the production and operation chain of enterprises. The size of their storage capacity is directly related to whether normal production and operation activities can be maintained. For existing multi-story finished product warehouse buildings, when planning to introduce finished product automated logistics systems, there are many limitations and challenges. The limitations of site space make it impossible to build an automated three-dimensional warehouse with multiple shelves. This type of automated vertical warehouse can usually make full use of vertical space and greatly improve storage capacity and storage efficiency. If it is used as a flat warehouse, even if the cargo space is planned according to the automatic in and out warehouse specifications, its storage capacity will inevitably shrink significantly because it cannot use space as efficiently as an automated vertical warehouse. This results in a limited number of finished products that can be supplied to the market, which in turn has a negative effect on the stable supply of finished products in the market. There may be situations such as untimely supply and backlog of orders, which will affect the company's market reputation and customer satisfaction, and ultimately interfere with the company's overall operating efficiency and market competitiveness. Summary of the invention

[0003] An object of the present invention is to provide a method for stacking and warehousing finished cigarette pallets to solve the aforementioned problem that the space limitations make it impossible to build an automated warehouse with multi-layer shelves, resulting in untimely supply, order backlogs and other problems.

[0004] According to a first aspect of the present invention, a method for stacking and warehousing finished cigarette trays is provided, comprising a stacking and warehousing step and an unstacking and warehousing step, wherein:

[0017] Optionally, in the step of the latent AGV transporting pallets in a specific alternating order, the specific alternating order is to transport the pallets in an alternating order of 30 pieces / pallet and 20 pieces / pallet.

[0018] Optionally, in the unpacking and warehousing step, the scheduling system arranges the latent AGV to perform the warehousing task, so that the latent AGV that has just completed warehousing on the same floor has priority to perform the warehousing task, and it picks up the goods at the designated docking station and transports them out of the warehouse in an alternating order.

[0019] Optionally, both the lurking AGV and the fork-type AGV establish real-time communication links with the scheduling system, and the lurking AGV and the fork-type AGV report their own positions, states, and task execution progress information to the scheduling system in real time.

[0020] Optionally, each stacking warehouse area is provided with 10 docking platforms, which are respectively set as A1, B1, C1, D1, E1, A2, B2, C2, D2, and E2, 2 in a group, totaling 5 groups, among which A1 and A2 are a group, B1 and B2 are a group, C1 and C2 are a group, D1 and D2 are a group, and E1 and E2 are a group. A1, B1, C1, D1, and E1 are placed on piece-filled cigarette pallets with 30 pieces / pallet, and A2, B2, C2, D2, and E2 are placed on piece-filled cigarette pallets with 20 pieces / pallet; piece-filled cigarette pallets with 20 pieces / pallet are stacked on piece-filled cigarette pallets with 30 pieces / pallet.

[0021] Optionally, in the stacking warehousing step, when the warehouse management system allocates a docking station for warehousing and releasing goods to the latent AGV, the task allocation is cyclically performed in the order of A1, A2, B1, B2, C1, C2, D1, D2, E1, and E2. When the fork-type AGV picks up goods from the docking station, it is also executed in the order of A1, A2, B1, B2, C1, C2, D1, D2, E1, and E2;

[0022] In the unpacking and outbound step, when the warehouse management system assigns the fork-type AGV to a docking station for outbound delivery, it cyclically allocates tasks in the order of A2, A1, B2, B1, C2, C1, D2, D1, E2, and E1. When the latent AGV picks up goods from the docking station, it also executes in the order of A2, A1, B2, B1, C2, C1, D2, D1, E2, and E1.

[0023] According to a second aspect of the present invention, a finished product pallet stacking and warehousing system is provided, including a warehouse management system, a dispatching system, an electric control system, a palletizing robot, a lurking AGV, a fork-type AGV, and a hoist: wherein:

[0024] Warehouse management system, used to generate and issue stacking warehousing task plans and generate outbound tasks based on outbound shipping orders;

[0025] A dispatching system, which is in communication with the warehouse management system, is used to receive the stacking warehousing task plan and the outbound task, and command the electric control system to perform the palletizing operation based on the stacking warehousing task plan, and arrange the lurking AGV to carry the pallet, arrange the forklift AGV to perform the picking and unloading operations, and arrange the forklift AGV to perform the unstacking task based on the outbound task;

[0026] An electric control system, which is in communication with the dispatching system, is used to receive instructions from the dispatching system and control the palletizing robots to perform alternate palletizing in a specific order;

[0027] The latent AGV is dispatched by the dispatching system to carry the pallets in a specific alternating sequence, transport them to the target floor via the elevator, and perform the unloading task at the corresponding docking station;

[0028] The fork-pick AGV is dispatched by the dispatching system to pick up 30 pieces / pallet of goods at the docking station and transport them to the designated cargo location at the target aisle entrance for unloading, and then returns to the docking station to pick up 20 pieces / pallet of goods, and also transports the 20 pieces / pallet of goods to the designated cargo location at the target aisle entrance and stacks them on the 30 pieces / pallet of goods to complete the warehousing task, and performs the unstacking task. First, it goes to the designated cargo location at the target aisle entrance to raise the arm to pick up the upper 20 pieces / pallet of goods, lowers the arm and transports it to the target docking station for unloading, and then goes to the designated cargo location at the target aisle entrance to pick up the lower 30 pieces / pallet of goods and transports them to the target docking station for unloading.

[0029] The method and system for stacking and warehousing finished cigarette pallets disclosed in the present invention have the following technical effects:

[0030] The dispatching system accurately directs the fork-type AGV to pick up goods of different numbers / pallets (30 pieces / pallet and 20 pieces / pallet) at the docking station, and accurately transports them to the designated cargo position at the target lane entrance, and then stacks them. It can flexibly respond to the storage needs of finished cigarettes with different packaging specifications, accurately place the goods in the appropriate position, further optimize the utilization of pallet space, and ensure that the goods accurately enter the corresponding position in the storage system.

[0031] The fork-type AGV first takes 20 pieces / pallet of goods from the upper layer, then takes 30 pieces / pallet of goods from the lower layer, and accurately transports them to the target docking station for unloading. In this way, the stacked goods on the pallet are accurately separated in sequence, which can ensure that the goods are not confused when leaving the warehouse and maintain the integrity of the goods.

[0032] The present invention realizes the highly automated, precise and orderly process of the finished cigarettes entering and leaving the warehouse through the coordination of the dispatching system, warehouse management system, different types of AGV (lurking type, fork-picking type), palletizing robots, hoists and other equipment. When entering the warehouse, the goods of different specifications can be stacked, transported and accurately placed in the warehouse cargo space in an orderly manner, improving the space utilization rate and warehouse efficiency; when leaving the warehouse, the stacked goods can be accurately split according to the order requirements, and the delivery preparation can be completed quickly and accurately, which improves the response speed to customer orders. At the same time, the whole process reduces the mistakes that may be caused by manual operation, and improves the overall level of warehouse management and operational efficiency.

[0033] 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

[0034] 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] 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.

[0038] 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.

[0039] 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 as part of the specification.

[0040] 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.

[0041] The present invention proposes an embodiment of a method for stacking and warehousing finished cigarette pallets. Specifically, Figure 1 As shown, it includes a stacking storage step and an unstacking storage step, wherein:

[0042] The steps for stacking and warehousing include:

[0043] The dispatching system instructs the electronic control system to make the palletizing robots stack alternately in a specific order according to the stacking and warehousing task plan issued by the warehouse management system;

[0044] The dispatching system arranges idle latent AGVs to move pallets in a specific alternating order according to the stacking storage tasks containing specific information, and then transports them to the target floor via the elevator;

[0045] The dispatching system instructs the fork-type AGV to pick up 30 pieces / pallet of goods at the docking station and transport them to the target aisle entrance. After unloading at the designated cargo location, it returns to the docking station to pick up 20 pieces / pallet of goods. The method of picking up different quantities of goods in two times can flexibly respond to the storage needs of finished cigarettes with different packaging specifications, optimizing the utilization of pallet space.

[0046] The fork-type AGV transports 20 pieces / pallet of goods to the target aisle entrance, stacks them on 30 pieces / pallet of goods at the designated cargo location to complete the warehousing, so that the entire pallet is filled with the appropriate number and specifications of finished parts; it can maximize the use of pallet space, increase the storage capacity of goods per unit pallet, and save storage space.

[0047] The steps of unpacking and unloading include:

[0048] The warehouse management system generates outbound tasks based on outbound delivery orders and sends them to the dispatching system, which then arranges the fork-pick AGV to perform the unpacking task.

[0049] The fork-pick AGV first goes to the designated cargo position at the target lane entrance, raises the fork arm to take 20 pieces / pallets of cargo from the upper layer, lowers the fork arm and transports the cargo to the target docking station for unloading;

[0050] The fork-type AGV then goes to the designated cargo location at the target aisle entrance to pick up 30 pieces / pallet of goods on the lower layer and transports them to the target docking station for unloading.

[0051] In the embodiment of the present invention, in the stacking and warehousing step, after each pallet is stacked, the pallet barcode is automatically bound to the No. 1 engineering code or quality traceability code of the cigarette. The staff only needs to scan the pallet barcode to quickly and accurately know the detailed information of all the cigarettes on the pallet, such as variety, quantity, production date, etc.

[0052] In the embodiment of the present invention, the stacking warehousing task containing specific information includes the palletizing station for picking up goods, the target floor for warehousing, and the warehouse area information.

[0053] In the embodiment of the present invention, the outbound task is an outbound task in the stacking warehouse area, and the task includes outbound brand, quantity, outbound floor, warehouse area and lane entrance information.

[0054] In an embodiment of the present invention, in the step of the latent AGV carrying the pallet in a specific alternating order, the specific alternating order is to carry the pallet of cigarettes in the order of 30 pieces / pallet and 20 pieces / pallet. This helps to achieve a relatively balanced distribution of the number of cigarettes in different storage areas or shelves in the warehouse. On the other hand, if the subsequent production links or processing procedures have specific requirements for the number of cigarettes, for example, a production line requires 30 cigarettes per batch for processing, and another production line requires 20 cigarettes per batch, then this alternating handling order can ensure the uninterrupted supply of materials on the production line, making the entire production process smoother and more efficient.

[0055] In an embodiment of the present invention, in the unpacking and warehousing step, the scheduling system arranges the latent AGV to perform the warehousing task, so that the latent AGV that has just completed warehousing on the same floor has priority to perform the warehousing task, so that the latent AGV can respond to the warehousing task faster, and it picks up and transports the goods out of the warehouse in an alternating order at the designated docking station, which standardizes the picking and transportation process at the docking station, making the entire warehousing process more standardized and predictable.

[0056] In the embodiment of the present invention, both the lurking AGV and the fork-pick AGV establish a real-time communication link with the dispatching system, and the lurking AGV and the fork-pick AGV report their own position, status, and task execution progress information to the dispatching system in real time. The communication link includes a wired or wireless communication method, such as Wi-Fi, Bluetooth, ZigBee, or industrial Ethernet, etc. The lurking AGV and the fork-pick AGV can receive instructions from the dispatching system in a timely manner, and can also feed back their own position, status, and task execution progress information to the dispatching system.

[0057] In the embodiment of the present invention, Figure 2 As shown, each stacking warehouse area is equipped with 10 docking stations, which are respectively set as A1, B1, C1, D1, E1, A2, B2, C2, D2, and E2, 2 in a group, a total of 5 groups, among which A1 and A2 are a group, B1 and B2 are a group, C1 and C2 are a group, D1 and D2 are a group, and E1 and E2 are a group. A1, B1, C1, D1, and E1 are placed on pallets with 30 pieces / pallet, and A2, B2, C2, D2, and E2 are placed on pallets with 20 pieces / pallet; pallets with 20 pieces / pallet are stacked on pallets with 30 pieces / pallet. This differentiated placement helps to classify and manage goods of different specifications, so that they can be stored in an orderly manner in the warehouse area, and can form a relatively stable stacking structure, reducing the risk of damage to goods due to shaking, tipping, etc. during storage in the warehouse area.

[0058] In the embodiment of the present invention, in the stacking warehousing step, when the warehouse management system allocates docking stations for the latent AGV to put goods in the warehouse, the task allocation is cyclically performed in the order of A1, A2, B1, B2, C1, C2, D1, D2, E1, and E2. When the fork-type AGV picks up goods from the docking station, it is also performed in the order of A1, A2, B1, B2, C1, C2, D1, D2, E1, and E2. By setting such a fixed order to allocate tasks and perform operations, there are clear and unified rules for the putting of goods by the latent AGV and the picking of goods by the fork-type AGV in the entire stacking warehousing link.

[0059] In the unpacking and outbound step, when the warehouse management system assigns the docking station for the fork-type AGV to release the goods, it cyclically allocates tasks in the order of A2, A1, B2, B1, C2, C1, D2, D1, E2, and E1. When the lurking AGV picks up the goods from the docking station, it also executes in the order of A2, A1, B2, B1, C2, C1, D2, D1, E2, and E1. According to this cyclic order, each docking station can be used more evenly. The fork-type AGV and the lurking AGV operate according to the same sequence rules in the unpacking and outbound stage, which enables them to cooperate better.

[0060] Specifically, Figure 2 As shown in the figure, when a certain warehouse area is used for double-layer stacking storage of cigarette pallets, the fork-pick AGV only operates in the warehouse area. The red and dark blue are its operation tracks. Its main operations are as follows:

[0061] a) During warehousing operations, the fork-type AGV picks up the pallets of cigarettes at the docking station, sends them to the storage location, and double-stacks the pallets of cigarettes as required;

[0062] b) During outbound operations, the fork-type AGV will unpack the stacked pallets and move them from the storage location to the docking station.

[0063] The latent AGV can run on all floors according to the system requirements. It can move goods on the same floor and change floors via the elevator. The cyan path is its running track. Figure 2 The main operations on the floors of the stacking warehouse area are as follows:

[0064] a) During the warehousing operation, the latent AGV moves the pallets of incoming goods to the stacking warehouse floor via the elevator, and delivers the pallets of incoming goods to the docking stations of each storage area as required;

[0065] b) During outbound operations, the lurking AGV will pick up the pallets of cigarettes from the docking stations in each storage area as required, then descend to the outbound floor via the elevator, and deliver the pallets of cigarettes to the storage location in the "outbound buffer area" for temporary storage, or directly to the depalletizing station in the depalletizing area for the cigarettes to be transported out of the warehouse.

[0066] In order to improve operating efficiency, the latent AGV needs to perform complex operations. After completing the task of moving the pallets of cigarettes into the warehouse, when returning, it moves the pallets of cigarettes that need to be shipped out to perform the outbound task to avoid returning empty.

[0067] The fork-type AGV and the lurking AGV each define their own operating areas, and set up traffic control strategies in the overlapping parts of the operating areas. When the paths of the lurking AGV and the fork-type AGV overlap when picking up or unloading goods at the docking station, when one of them is operating in the overlapping area, the other is not allowed to enter the area. Only when the AGV in the overlapping area leaves can the other enter the area to perform tasks.

[0068] In another embodiment of the present invention, the method for stacking and warehousing finished cigarette pallets includes the following process:

[0069] Stacking storage process:

[0070] 1. The warehouse management system generates a stacking and warehousing task plan and forwards it to the scheduling system. The scheduling system issues instructions to the electronic control system to control the palletizing robot to perform the palletizing tasks in the order of 30 pieces / pallet and 20 pieces / pallet. After each pallet is palletized, the system automatically binds the pallet barcode (or pallet RFID ID number) with the piece-to-piece engineering code or quality traceability code.

[0071] 2. The electronic control system sends an application to the warehouse management system, which generates a stacking and warehousing task (including the stacking station for picking up goods, the target floor for warehousing, and the warehouse area, etc.), and forwards it to the dispatching system. The dispatching system issues instructions to the latent AGV system to dispatch the nearest idle AGV to perform the picking task. The latent AGVs carry the pallets in alternating order of 30 pieces / pallet and 20 pieces / pallet, and ascend to the target floor via the elevator.

[0072] 3. The latent AGV moves the cargo to the door of the target warehouse area and applies to the warehouse management system. The warehouse management system informs it of the specific docking station for unloading the cargo. The latent AGV applies to the dispatching system to enter the target docking station. After confirmation by the dispatching system, the latent AGV enters the docking station to perform the unloading task, and then applies to the dispatching system to leave.

[0073] 4. The dispatching system issues instructions to the fork-pick AGV system, dispatching the fork-pick AGV to perform the stacking warehousing task. Before the fork-pick AGV moves to the docking station, it initiates an application in advance. The warehouse management system informs it of the specific docking station for picking up goods. The fork-pick AGV applies to the dispatching system to enter the target docking station. After the dispatching system confirms, the fork-pick AGV enters the docking station to perform the task of picking up 30 pieces / pallet, and then applies to the dispatching system to leave.

[0074] 5. The fork-type AGV moves the pallet to the target aisle entrance and applies to the warehouse management system. The warehouse management system informs it of the specific cargo location. The fork-type AGV applies to the dispatching system to enter the target cargo location. After the dispatching system confirms, the fork-type AGV enters the cargo location to perform the unloading task of 30 pieces / pallet, and then applies to the dispatching system to leave.

[0075] 6. Before the fork-type AGV continues to move to the docking station, it initiates an application in advance. The warehouse management system informs it of the specific docking station for picking up goods. The fork-type AGV applies to the scheduling system for entering the target docking station. After the scheduling system confirms, the fork-type AGV enters the docking station to perform the task of picking up 20 pieces / pallet, and then applies to the scheduling system to leave.

[0076] 7. The fork-type AGV moves the piece-smoked pallet to the target aisle entrance and applies to the warehouse management system. The warehouse management system informs it of the specific storage location. The fork-type AGV applies to the scheduling system to enter the target storage location. After the scheduling system confirms, the fork-type AGV arm rises to the preset height (that is, a height slightly higher than the piece-smoked pallet with 30 pieces / pallet), enters the storage location, and places the piece-smoked pallet with 20 pieces / pallet on the piece-smoked pallet with 30 pieces / pallet, completing the stacking and warehousing task. Then, the fork-type AGV applies to the scheduling system to leave and continue to execute the next stacking task.

[0077] 8. When the warehouse management system assigns docking stations for the latent AGV to put goods into the warehouse, it cyclically allocates tasks in the order of A1, A2, B1, B2, C1, C2, D1, D2, E1, and E2. When the fork-type AGV picks up goods from the docking station, it also follows this order.

[0078] Unpacking and delivery process:

[0079] 1. The warehouse management system generates the outbound task of the stacking warehouse area (including outbound brand, quantity, outbound floor, warehouse area and lane entrance information) according to the outbound delivery order, and sends it to the dispatching system. The dispatching system issues the task to the fork-type AGV system, and dispatches the fork-type AGV to perform the unstacking task.

[0080] 2. The fork-type AGV moves to the target aisle entrance and initiates an application in advance. The warehouse management system informs it of the specific pickup location. The fork-type AGV applies to the scheduling system for entry into the target location. After confirmation by the scheduling system, the fork-type AGV arm rises to the preset height, enters the location, and picks up the piece-filled pallet with 20 pieces / pallet on the upper layer. After exiting the location, the arm carrying the piece-filled pallet drops to a low position, and then applies to the scheduling system to leave.

[0081] 3. The fork-type AGV moves the pallet to the target docking station and applies to the warehouse management system. The warehouse management system informs it of the specific docking station for unloading. The fork-type AGV applies to the dispatching system to enter the target docking station. After the dispatching system confirms, the fork-type AGV enters the cargo location to perform the unloading task of 20 pieces / pallet, and then applies to the dispatching system to leave.

[0082] 4. The fork-type AGV continues to move to the target aisle entrance and initiates an application in advance. The warehouse management system informs it of the specific pickup location. The fork-type AGV applies to the dispatching system to enter the target location. After the dispatching system confirms, the fork-type AGV enters the location, picks up the pallet with 30 pieces / pallet on the lower layer, and then applies to the dispatching system to leave.

[0083] 5. The fork-type AGV moves the pallet to the target docking station and applies to the warehouse management system. The warehouse management system informs it of the specific docking station for unloading. The fork-type AGV applies to the dispatching system to enter the target docking station. After the dispatching system confirms, the fork-type AGV enters the cargo location to perform the unloading task of 20 pieces / pallet, and then applies to the dispatching system to leave.

[0084] 6. The dispatching system issues instructions to the latent AGV system to dispatch the latent AGV to perform the outbound task. The latent AGV on the same floor that has just completed the inbound task is given priority in the outbound task to achieve compound operations.

[0085] 7. The lurking AGV moves to the target docking station and applies to the warehouse management system in advance. The warehouse management system informs it of the specific docking station for picking up goods. The lurking AGV applies to the dispatching system to enter the target docking station. After the dispatching system confirms, the lurking AGV enters the docking station to perform the picking task, and then applies to the dispatching system to leave. The lurking AGV transports the pieces and pallets out of the warehouse in the order of 20 pieces / pallet and 30 pieces / pallet.

[0086] 8. When the warehouse management system assigns a docking station for the fork-type AGV to release goods, it cyclically allocates tasks in the order of A2, A1, B2, B1, C2, C1, D2, D1, E2, and E1. When the latent AGV picks up goods from the docking station, it also follows this order.

[0087] The present invention also provides an embodiment of a finished product pallet stacking and warehousing system, including a warehouse management system, a dispatching system, an electric control system, a palletizing robot, a lurking AGV, a fork-type AGV, and a hoist: wherein:

[0088] Warehouse management system, used to generate and issue stacking warehousing task plans and generate outbound tasks based on outbound shipping orders;

[0089] A dispatching system, which is in communication with the warehouse management system, is used to receive the stacking warehousing task plan and the outbound task, and command the electric control system to perform the palletizing operation based on the stacking warehousing task plan, and arrange the lurking AGV to carry the pallet, arrange the forklift AGV to perform the picking and unloading operations, and arrange the forklift AGV to perform the unstacking task based on the outbound task;

[0090] An electric control system, which is in communication with the dispatching system, is used to receive instructions from the dispatching system and control the palletizing robots to perform alternate palletizing in a specific order;

[0091] The latent AGV is dispatched by the dispatching system to carry the pallets in a specific alternating sequence, transport them to the target floor via the elevator, and perform the unloading task at the corresponding docking station;

[0092] The fork-pick AGV is dispatched by the dispatching system to pick up 30 pieces / pallet of goods at the docking station and transport them to the designated cargo location at the target aisle entrance for unloading, and then returns to the docking station to pick up 20 pieces / pallet of goods, and also transports the 20 pieces / pallet of goods to the designated cargo location at the target aisle entrance and stacks them on the 30 pieces / pallet of goods to complete the warehousing task, and performs the unstacking task. First, it goes to the designated cargo location at the target aisle entrance to raise the arm to pick up the upper 20 pieces / pallet of goods, lowers the arm and transports it to the target docking station for unloading, and then goes to the designated cargo location at the target aisle entrance to pick up the lower 30 pieces / pallet of goods and transports them to the target docking station for unloading.

[0093] The warehouse management system in the present invention can automatically generate stacking warehousing task plans and outbound tasks according to actual business needs, avoiding the tediousness and omissions of manual task planning. In the warehousing stage, the lurking AGV transports pallets in a specific alternating order, and the fork-type AGV accurately takes different quantities of goods and stacks them; in the outbound stage, the fork-type AGV can accurately perform the unpacking task and transport the goods to the designated location. The various devices are closely coordinated and connected in an orderly manner, avoiding idle equipment waiting or operation conflicts. After receiving the instructions from the scheduling system, the electronic control system controls the stacking robot to stack alternately in a specific order.
