Description

Technical Field

[0001] The present invention relates to the technical field of cigarette manufacturing, and more specifically, to a whole pallet outbound storage system and method. Background Art

[0002] In the logistics chain of the tobacco industry, the industrial and commercial transport and delivery link involves the loading, unloading and handling of many goods. In the past, there were many disadvantages when relying on manual loading, unloading and handling. For example, each piece of goods needs to be transferred manually, which is a cumbersome and time-consuming process. Especially in the case of large-scale shipments, the time for loading and unloading goods will be very long, which seriously affects the efficiency of logistics. Moreover, long-term and high-intensity manual handling work consumes a lot of workers' physical strength, and the labor intensity remains high.

[0003] Through pallet intermodal transport, goods can be stacked on pallets in advance at the industrial enterprise end according to certain rules, forming units that are easy to handle and transport. This avoids the confusion and repetitive labor in the previous handover of scattered goods, and greatly improves the smoothness and efficiency of logistics docking between industrial and commercial enterprises. In the actual implementation process, pallet intermodal transport involves coordination and cooperation in many aspects, such as the unification of pallet specifications and standards, the docking of information systems between different enterprises, the fixation and protection of pallets during transportation, and other operating mode-related contents that all need to be carefully designed and standardized. At the same time, there will also be difficult problems such as how to deal with pallet loss and damage, and the poor compatibility of loading and unloading equipment of different enterprises with pallet intermodal transport. These all require industrial and commercial enterprises to discuss together and find practical solutions to ensure that pallet intermodal transport can be smoothly implemented and give play to the expected advantages.

[0004] When a full pallet is shipped out of the warehouse, it is usually shipped in a pallet of 30 pieces / pallet or 24 pieces / pallet according to the specific requirements of the delivery order. However, since there may be multiple pallet types coexisting in the palletizing process within industrial enterprises, in order to meet the requirements of shipping in a specific pallet type, when studying the full pallet delivery system, it is necessary to consider the function of converting 30 pieces / pallet or other specifications of pallet types into 24 pieces / pallet specifications of pallet types. This is also a problem that industrial and commercial enterprises need to explore and solve. Summary of the invention

[0005] One object of the present invention is to provide a whole-pallet outbound delivery system and method to solve the aforementioned problems of pallet loss and damage, poor compatibility of loading and unloading equipment of different enterprises with pallet intermodal transport, and lack of function to convert pallet type into 24 pieces / pallet specification pallet type.

[0006] According to a first aspect of the present invention, a whole pallet outbound system is provided, comprising a palletizing robot, a cigarette cache channel, a cigarette return channel, a latent AGV, a hoist, a pallet loading device and a whole pallet outbound line; wherein:

[0007] The palletizing robot depalletizes the finished cigarette pallets located at the depalletizing station, and grabs the cigarettes again for repalletizing;

[0008] The cigarette piece buffer channel is used to temporarily store the cigarette pieces removed from the depalletizing station by the palletizing robot, so that the cigarette pieces can enter the palletizing channel again, so that the palletizing robot can re-palletize;

[0009] The cigarette piece return channel is used to cooperate with the cigarette piece buffer channel to make the cigarette pieces return to the stacking channel after being depalletized;

[0010] The latent AGV is used to move to the designated cargo position in the outbound buffer area to pick up the finished cigarette pallet and transport it to the pallet on-line device, and to move to the designated cargo position on the target floor to pick up the finished cigarette pallet, and then transport it to the docking station on the same floor after descending to the outbound floor by the elevator, and then transport it from the docking station to the pallet on-line device;

[0011] The pallet on-line device is used to receive the pallet of finished cigarette parts transported by the latent AGV;

[0012] The whole pallet outbound line provides a conveying channel for the finished cigarette pallets so that they can be transported to the shipping area for whole pallet loading and shipping.

[0013] Optionally, the palletizing robot palletizes the finished cigarette pieces in a pallet shape of 24 pieces / pallet onto an empty pallet with a paper slide pallet, and binds the pallet barcode, the cigarette piece No. 1 engineering code, and the pallet RFID ID number.

[0014] Optionally, the whole pallet outbound system further comprises a film wrapping machine, which is located on the outbound conveyor line and performs film wrapping operations on the passing pallets of finished cigarettes according to the delivery requirements.

[0015] Optionally, the whole pallet outbound system also includes a barcode recognition device, which is arranged in a position before the film wrapping, and is used to verify the RFID information of the finished product pallet. When the verification is passed, the finished product pallet is allowed to enter the film wrapping station for film wrapping. When the verification fails, the finished product pallet is allowed to enter the abnormal processing port.

[0016] Optionally, before transporting the finished cigarette pallet to the pallet online device, the latent AGV sends a release request signal. After the electronic control system confirms the release request signal, the latent AGV transports the finished cigarette pallet to the pallet online device, completes the unloading task, and applies to the scheduling system to leave.

[0017] Optionally, when the warehouse management system detects that the information of a docking station is empty and determines that the current shipment quantity does not meet the order requirements, it immediately generates a new outbound task and sends it to the scheduling system, and issues a scheduling instruction to the latent AGV system to schedule the idle latent AGV to perform the picking task and add the finished product pallets to the docking station with empty information.

[0018] According to a second aspect of the present invention, a method for removing a whole pallet from a warehouse is provided, including a whole pallet removal process of a finished product cigarette pallet, specifically comprising:

[0019] Outbound from the outbound buffer area: The latent AGV goes to the designated cargo location in the outbound buffer area to pick up the corresponding finished product pallet, and transports it to the pallet loading device. The finished product pallet is lifted to the same height as the outbound conveyor line by the pallet loading device, and then transported to the film wrapping station of the film wrapping machine via the outbound conveyor line. After the finished product pallet is film wrapped, it is transported to the shipping area via the corridor pallet conveyor line, and the whole pallet is loaded and shipped;

[0020] Cross-floor delivery: The lurking AGV goes to the designated cargo location on the target floor to pick up the corresponding finished product pallet, descends to the delivery floor via the elevator, and delivers it to the three docking stations on the same floor for temporary storage of the finished product pallets. The lurking AGV moves the finished product pallet from the docking station to the pallet loading device. The finished product pallet is lifted to the same height as the delivery conveyor line by the pallet loading device, and is transported to the wrapping station of the wrapping machine via the delivery conveyor line. After the finished product pallet is wrapped, it is transported to the shipping area via the corridor pallet conveyor line, and the entire pallet is loaded and shipped.

[0021] Optionally, before wrapping, the RFID information of the cigarette tray is verified by a barcode recognition device, and the film is wrapped only after the verification is passed, otherwise it enters the abnormal processing port for manual processing.

[0022] Optionally, the whole pallet outbound method also includes an operation process of automatically stacking the pallets that have been put into storage into 24 pieces / pallet, which specifically includes:

[0023] Outbound delivery from the outbound buffer area: The lurking AGV goes to the designated cargo location to pick up the corresponding pallet and transports it to the depalletizing station in the palletizing area;

[0024] Cross-floor delivery: The lurking AGV goes to the designated cargo location on the target floor to pick up the corresponding finished product pallet, descends to the delivery floor via the elevator, and transports it to the depalletizing station in the palletizing area;

[0025] The palletizing robot depalletizes the finished cigarette pallets on the depalletizing station. The cigarette pieces enter the palletizing channel again through the buffer channel. The palletizing robot grabs the cigarette pieces again and palletizes them on the empty pallet with the paper slide pallet. The pallet is repalletized in the shape of 24 pieces / pallet, and the pallet barcode, cigarette piece No. 1 engineering code, and pallet RFID ID number are bound.

[0026] The latent AGV moves the solid pallet to the full pallet outbound conveyor line, and then directly wraps it and puts it back into the warehouse or ships the whole pallet directly.

[0027] The whole pallet outbound system and method disclosed in the present invention have the following technical effects:

[0028] The present invention has built an automatic outbound system for whole pallets, wherein the palletizing robot can depalletize the finished cigarette pallets located at the depalletizing station, and grab the cigarettes again and re-palletize them into a pallet shape of 24 pieces / pallet, and can flexibly adjust the loading capacity and pallet shape according to different delivery order requirements. During the re-palletizing process, the pallet barcode, the cigarette piece No. 1 engineering code, and the pallet RFID ID number are bound to achieve a deep association between the pallet and the cigarette piece information, which is helpful for accurate tracking and management of goods in the entire logistics supply chain.

[0029] When the palletizing robot is performing the depalletizing operation, the depalletized pieces first enter the cache channel, wait for the palletizing robot to complete the current task, and then return to the palletizing area through the reflux channel in an orderly manner for re-palletizing, thereby improving the utilization rate of the equipment and the overall operating efficiency.

[0030] The lurking AGV works in conjunction with the elevator to fully utilize the three-dimensional space of the warehouse and realize the rapid deployment and delivery of goods on different floors. The pallet loading device receives the finished product pallets transported by the lurking AGV and lifts them to the same height as the delivery conveyor line, ensuring that the pallets can smoothly transition from the handling link to the delivery link, avoiding problems such as pallet jamming and falling due to height difference or speed mismatch, and improving the stability and smoothness of the entire delivery process.

[0031] The full-pallet outbound line provides a dedicated conveying channel for finished product pallets, so that they can be stably and orderly transported to the shipping area for full-pallet loading and shipment, improving the accuracy and efficiency of full-pallet shipment.

[0032] 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

[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 as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0042] The present invention proposes an embodiment of a whole pallet outbound system. Specifically, Figure 1 and Figure 2 As shown, the whole pallet outbound system is divided into four areas, the first area is the palletizing area, the second area is the depalletizing outbound area and the whole pallet outbound area, the third area and the fourth area are both outbound buffer areas, and the whole pallet outbound system includes a palletizing robot 1, a cigarette cache channel 2, a cigarette return channel 3, a latent AGV 4, an elevator 5, a pallet on-line device 8 and a whole pallet outbound line 9; wherein:

[0043] The palletizing robot 1 depalletizes the finished cigarette pieces on the depalletizing station 6, and grabs the cigarette pieces again for re-palletizing; the palletizing robot 1 separates the cigarette pieces from the pallet in an orderly manner through its precise mechanical arm motion control and visual recognition system.

[0044] The cigarette piece buffer channel 2 is used to temporarily store the cigarette pieces removed by the palletizing robot 1 from the depalletizing station 6, so that the cigarette pieces can enter the palletizing channel again and the palletizing robot 1 can re-palletize; the cigarette piece buffer channel 2 can be a chain conveyor belt, a belt conveyor belt or a buffer device with multiple storage compartments, etc., and its parameters such as length, width and conveying speed can be adjusted according to the actual cigarette piece flow rate.

[0045] The cigarette return channel 3 is used to cooperate with the cigarette buffer channel 2 to make the cigarette return to the palletizing channel after depalletizing; the cigarette return channel 3 is mainly responsible for guiding the cigarette temporarily stored in the buffer channel back to the palletizing channel so that the palletizing robot 1 can re-palletize. A guide plate with a certain curvature is set at the turning point of the cigarette return channel 3, and the inertia of the cigarette itself and the friction of the conveyor belt are used to make the cigarette change direction smoothly and return to the palletizing channel smoothly.

[0046] The latent AGV4 is used to move to the designated cargo location in the outbound buffer area to pick up the pallet of finished cigarette parts and transport them to the pallet online device 8, and to move to the designated cargo location on the target floor to pick up the pallet of finished cigarette parts, and then descend to the outbound floor via the elevator 5 and transport it to the docking platform 13 on the same floor, and then transport it from the docking platform 13 to the pallet online device 8; the latent AGV4 ensures that the pallet can accurately reach the corresponding position of each key link, avoiding problems such as subsequent process jams or equipment docking failures caused by deviations in the transport position.

[0047] The pallet loading device 8 is used to receive the finished cigarette pallet transported by the latent AGV 4; the pallet loading device 8 adjusts the height of the finished cigarette pallet transported by the latent AGV 4 so that it can be smoothly connected to the whole pallet outbound line 9 for subsequent transportation. The pallet loading device 8 adopts an electric lifting structure, and the motor drives the pallet carrying platform to move up and down.

[0048] Full pallet outbound line 9: provides a conveying channel for the finished cigarette pallets so that they can be transported to the shipping area for full pallet loading and shipping; the full pallet outbound line 9 adopts a combination of chain conveyor and roller conveyor. The chain conveyor part is used to provide stable traction to ensure that the whole pallet can continue to move forward, while the roller conveyor part can better adapt to the structural characteristics of the bottom of the pallet, reduce friction, and make the transportation of the whole pallet smoother.

[0049] In the embodiment of the present invention, the palletizing robot 1 palletizes the finished cigarette pallets in a stacking shape of 24 pieces / pallet onto an empty pallet with a paper slide pallet, and binds the pallet barcode, the cigarette No. 1 engineering code, and the pallet RFID ID number. The palletizing robot 1 can operate strictly according to the set stacking shape, avoiding problems such as uneven placement and inaccurate quantity caused by manual operation. Information binding helps logistics companies to grasp the accurate location, status and other information of the goods in real time.

[0050] In the embodiment of the present invention, the whole pallet outbound system further includes a film wrapping machine 11, which is located on the outbound conveyor line and performs film wrapping operations on the finished cigarette pallets passing through according to the delivery requirements. A continuous plastic film protective layer is formed on the outside of the pallet after film wrapping, which effectively blocks the entry of external moisture and dust, and reduces the probability of damage such as bruises and deformation of the cigarette pieces.

[0051] In an embodiment of the present invention, the whole pallet outbound system also includes a barcode recognition device 10, which is arranged in a position before the film wrapping, and is used to verify the RFID (radio frequency identification) information of the finished product pallet. When the verification is passed, the finished product pallet is allowed to enter the film wrapping station for film wrapping. When the verification fails, the finished product pallet is allowed to enter the abnormal processing port 12 for manual processing.

[0052] In the embodiment of the present invention, the latent AGV 4 sends a release signal before transporting the finished cigarette pallet to the pallet on-line device 8. After the electric control system confirms the release signal, the latent AGV 4 transports the finished cigarette pallet to the pallet on-line device 8, completes the unloading task, and applies to the dispatching system to leave. This avoids collisions with other running equipment and accidental damage to the pallet on-line device 8 caused by the latent AGV 4 releasing goods at will.

[0053] In the embodiment of the present invention, when the warehouse management system detects that the information of a docking station 13 is empty and determines that the current shipment quantity does not meet the order requirements, it immediately generates a new outbound task and sends it to the dispatching system, and sends a dispatching instruction to the latent AGV4 system to dispatch the idle latent AGV4 to perform the pickup task and replenish the finished product pallet to the docking station 13 with empty information. By timely discovering that the docking station 13 is out of stock and quickly generating outbound tasks and dispatching the latent AGV4 to replenish the goods, the waiting time during the delivery process is reduced, ensuring that the docking station 13 is always in stock or quickly recovers to the stock state, making the logistics process smoother.

[0054] The present invention also provides an embodiment of a whole pallet outbound method, including a whole pallet outbound process of finished cigarette parts, specifically comprising:

[0055] Outbound delivery from the outbound delivery buffer area: the lurking AGV4 goes to the designated cargo position in the outbound delivery buffer area to pick up the corresponding finished product pallet, and transports it to the pallet loading device 8. The finished product pallet is lifted to the same height as the outbound delivery conveyor line by the pallet loading device 8, and is transported to the film wrapping station of the film wrapping machine 11 via the outbound delivery conveyor line. After the finished product pallet is film wrapped, it is transported to the delivery area via the corridor pallet conveyor line, and the whole pallet is loaded and shipped;

[0056] Cross-floor delivery: The lurking AGV4 goes to the designated cargo location on the target floor to pick up the corresponding finished product pallet, descends to the delivery floor via the elevator 5, and delivers it to the three docking stations 13 on the same floor for temporary storage of the finished product pallets. The lurking AGV4 moves the finished product pallet from the docking station 13 to the pallet loading device 8. The finished product pallet is lifted to the same height as the delivery conveyor line by the pallet loading device 8, and is transported to the wrapping station of the wrapping machine 11 via the delivery conveyor line. After the finished product pallet is wrapped, it is transported to the shipping area via the corridor pallet conveyor line, and the entire pallet is loaded and shipped.

[0057] In the embodiment of the present invention, the RFID information of the cigarette tray is first verified by the barcode recognition device 10 before wrapping, and the cigarettes are wrapped only after the verification is passed. Otherwise, they enter the abnormal processing port 12 for manual processing.

[0058] In an embodiment of the present invention, the whole pallet outbound method also includes an operation process of automatically stacking the pallets that have been put into storage into 24 pieces / pallet, which specifically includes:

[0059] Outbound delivery from the outbound buffer area: Lurking AGV4 goes to the designated cargo location to pick up the corresponding pallet of cigarettes, and transports it to the depalletizing station 6 in the palletizing area;

[0060] Cross-floor delivery: The lurking AGV 4 goes to the designated cargo position on the target floor to pick up the corresponding finished product pallet, which is then lowered to the delivery floor via the elevator 5 and transported to the depalletizing station 6 in the palletizing area;

[0061] The palletizing robot 1 depalletizes the finished cigarette pallets on the depalletizing station 6. The cigarette pieces enter the palletizing channel again through the buffer channel. The palletizing robot 1 grabs the cigarette pieces again and palletizes them on the empty pallet with the paper slide pallet. The palletizing is performed again in the shape of 24 pieces / pallet, and the pallet barcode, the cigarette piece No. 1 engineering code, and the pallet RFID ID number are bound.

[0062] The latent AGV4 takes the solid pallet of cigarettes and sends it to the full pallet outbound conveyor line, which directly wraps it and then puts it back into the warehouse or ships the whole pallet directly.

[0063] The present invention also provides another embodiment of a method for removing a whole pallet from a warehouse, which specifically includes the following process:

[0064] 1. The operator manually enters the full pallet delivery plan, including the delivery brand, quantity and other information. The warehouse management system generates the full pallet outbound task according to the delivery plan, including the outbound brand, quantity, target floor and lane, pallet stacking type and other information. The dispatching system issues a handling instruction to the latent AGV4 system, dispatching the nearest latent AGV4 to perform the task.

[0065] 2. Outbound delivery from the delivery buffer area: The lurking AGV4 moves to the target lane entrance of the delivery buffer area and applies for a cargo location. The warehouse management system informs it of the specific cargo location for picking up goods. The lurking AGV4 applies to the dispatching system for entering the target cargo location. After confirmation by the dispatching system, the lurking AGV4 enters the cargo location to perform the picking up task, and then applies to the dispatching system to leave. The lurking AGV4 moves the finished product pallet to the pallet on-line device 8 and applies to release the goods. After confirmation by the electronic control system, the lurking AGV4 moves the finished product pallet to the pallet on-line device 8, completes the unloading task, and applies to the dispatching system to leave. The electric control system controls the pallet on-line device 8 to be lifted to the same height as the outbound conveyor line, and then goes through the outbound conveyor line to the information verification station, where the barcode recognition device 10 identifies the piece-size cigarette pallet information and verifies it with the task issued by the system. If the verification is correct, the piece-size cigarette pallet is conveyed to the wrapping station of the wrapping machine 11. After the electric control system detects the in-position signal, it controls the wrapping machine 11 to wrap the finished piece-size cigarette pallet, and transports it to the shipping area via the corridor pallet conveyor line, where the entire pallet is loaded and shipped; the pallets that fail the verification are sent to the abnormal processing port 12 for manual processing.

[0066] 3. Cross-floor delivery: The latent AGV4 moves to the entrance of the lane on the target floor and applies for a cargo location. The warehouse management system informs it of the specific cargo location for picking up goods. The latent AGV4 applies to the dispatching system for entry into the target cargo location. After confirmation by the dispatching system, the latent AGV4 enters the cargo location to perform the pickup task, and then applies to the dispatching system for leaving. The latent AGV4 moves the finished product pallet to the elevator 5, sends an entry application to the elevator 5 system, and informs the target floor. After the elevator 5 system allows, the rapid lifting shutter door is opened, and the latent AGV4 enters the elevator 5 with cargo. The rapid lifting shutter door is closed. After the electric control system confirms that the latent AGV4 is in place, the elevator 5 descends to the delivery area floor. The latent AGV4 sends a departure application signal to the elevator 5 system. The elevator 5 system confirms that the equipment is parked in place, opens the rapid lifting shutter door, and allows the latent AGV4 to leave.

[0067] The lurking AGV4 carries the finished product pallet and delivers it to the docking station 13 in the full pallet outbound area, where it applies for release. The warehouse management system informs the specific docking station 13 for release, and the lurking AGV4 applies to the dispatching system to enter the target docking station 13. After the dispatching system confirms, the lurking AGV4 enters the docking station 13 to perform the unloading task, and then applies to the dispatching system to leave. When the three docking stations 13 in the full pallet outbound area are full, the system starts to execute the full pallet outbound task of this batch.

[0068] The dispatching system issues a command to the latent AGV4 system, dispatching the latent AGV4 to the docking station 13 to pick up the finished product pallet. The latent AGV4 goes to the designated docking station 13 according to the task requirements to carry the finished product pallet to the pallet on-line device 8, and applies for releasing the goods. After the electronic control system confirms, the latent AGV4 carries the finished product pallet to the pallet on-line device 8, completes the unloading task, and applies to the dispatching system to leave. The electronic control system controls the pallet on-line device 8 to be lifted to the same height as the outbound conveyor line, and then goes to the information verification station via the outbound conveyor line. The barcode recognition device 10 recognizes the information of the finished product pallet, and verifies it with the task issued by the system. If the verification is correct, the finished product pallet is then transported to the film wrapping station of the film wrapping machine 11. After the electronic control system detects the in-position signal, it controls the film wrapping machine 11 to film the finished product pallet, and then transports it to the shipping area via the corridor pallet conveyor line. The whole pallet is loaded and shipped. The pallet that fails the verification is sent to the abnormal processing port 12 for manual processing.

[0069] 4. The warehouse management system detects that the information of a certain docking station 13 is empty, and determines that the current delivery quantity does not meet the order requirements. It immediately generates a new outbound task, sends it to the scheduling system, and issues instructions to the latent AGV4 system to schedule the idle latent AGV4 to perform the picking task and replenish the finished product pallets to the docking station 13.

[0070] 5. Automatic palletizing of pallets that have been put into storage is 24 pieces / pallet operation process:

[0071] The warehouse management system generates a full-pallet outbound task based on the manually entered delivery plan, automatically plans the task brand, quantity, target floor and lane information of converting 30 pieces / pallet into 24 pieces / pallet, and forwards it to the dispatching system. The dispatching system issues a handling task to the latent AGV4 system and dispatches the nearest latent AGV4 to perform the task. The warehouse management system also adjusts the function of the palletizing station 7 on the easternmost side of the No. 1 palletizing robot 1 to the depalletizing station 6, prohibiting the station from supplementing empty pallets, and allowing the task of supplementing full pallets.

[0072] Outbound delivery from the delivery buffer area: The lurking AGV4 moves to the target lane entrance of the delivery buffer area and applies for a cargo location. The warehouse management system informs it of the specific cargo location for picking up goods. The lurking AGV4 applies to the dispatching system for entry into the target cargo location. After confirmation by the dispatching system, the lurking AGV4 enters the cargo location to perform the picking task, and then applies to the dispatching system to leave. The lurking AGV4 transports the solid pallet to the depalletizing station 6 in the palletizing area and applies to enter. After confirmation by the dispatching system, the lurking AGV4 enters the depalletizing station 6 to unload the goods. After unloading is completed, it applies to the dispatching system to leave.

[0073] Cross-floor delivery: The latent AGV4 moves to the entrance of the lane on the target floor and applies for a cargo location. The warehouse management system informs it of the specific cargo location for picking up goods. The latent AGV4 applies to the dispatching system for entry into the target cargo location. After confirmation by the dispatching system, the latent AGV4 enters the cargo location to perform the pickup task, and then applies to the dispatching system for leaving. The latent AGV4 moves the finished product pallet to the elevator 5, sends an entry application to the elevator 5 system, and informs the target floor. After the elevator 5 system allows, the rapid lifting shutter door is opened, and the latent AGV4 enters the elevator 5 with cargo. The rapid lifting shutter door is closed. After the electric control system confirms that the latent AGV4 is in place, the elevator 5 descends to the delivery area floor. The latent AGV4 sends a departure application signal to the elevator 5 system. The elevator 5 system confirms that the equipment is parked in place, opens the rapid lifting shutter door, and allows the latent AGV4 to leave. The latent AGV4 transports the solid pallet to the depalletizing station 6 in the palletizing area and applies for entry. After confirmation by the dispatching system, the latent AGV4 enters the depalletizing station 6 to unload. After unloading is completed, it applies to the dispatching system to leave.

[0074] The palletizing robot 1 depalletizes the finished product pallets of 30 pieces / pallet on the depalletizing station 6. The finished product pieces enter the piece buffer channel 2 for palletizing again through the piece return channel 3. The palletizing robot 1 grabs the pieces again and re-palletizes them on the empty pallet in the shape of 24 pieces / pallet, and automatically binds the pallet barcode, piece No. 1 engineering code, and pallet RFID ID number.

[0075] After palletizing station 7 completes the palletizing of 24 pieces / pallet, the electronic control system sends an application, the warehouse management system generates a task, and sends it to the dispatching system. The dispatching system sends an instruction to the latent AGV4 system to dispatch the nearest idle latent AGV4 to perform the task of picking up goods. Before the latent AGV4 moves to the palletizing station 7, it sends an application to the dispatching system. After the dispatching system confirms, the latent AGV4 is allowed to enter the palletizing station 7. After the latent AGV4 picks up the goods, it sends an application to the dispatching system. After the dispatching system confirms, the latent AGV4 leaves with the goods.

[0076] Before the latent AGV4 carries the finished product pallet to the pallet loading device 8, it applies for releasing the goods. After the electric control system confirms, the latent AGV4 carries the finished product pallet to the pallet loading device 8, completes the unloading task, and applies to the dispatching system to leave. The electric control system controls the pallet loading device 8 to be lifted to the same height as the outbound conveyor line, and then passes through the outbound conveyor line to the information verification station. The barcode recognition device 10 recognizes the information of the finished product pallet, and verifies it with the task issued by the system. If the verification is correct, the finished product pallet is transported to the film wrapping station of the film wrapping machine 11. After the electric control system detects the in-position signal, it controls the film wrapping machine 11 to wrap the finished product pallet, and then transports it to the shipping area via the corridor pallet conveyor line.

2. The whole pallet outbound system according to claim 1 is characterized in that: The palletizing robot palletizes the finished cigarette pieces on the empty pallet with the paper slide pallet in a stacking shape of 24 pieces / pallet, and binds the pallet barcode, the cigarette piece No. 1 engineering code, and the pallet RFID ID number.

3. The whole pallet outbound system according to claim 1 is characterized in that: It also includes a film wrapping machine, which is located on the outbound conveyor line and performs film wrapping operations on the finished cigarette pallets passing through according to the delivery requirements.

4. The whole pallet outbound system according to claim 3 is characterized in that: It also includes a barcode recognition device, which is arranged in a position before the film wrapping, and is used to verify the RFID information of the finished product pallet. When the verification is passed, the finished product pallet is allowed to enter the film wrapping station for film wrapping. When the verification fails, the finished product pallet is allowed to enter the abnormal processing port.

5. The whole pallet outbound system according to claim 1 is characterized in that: Before transporting the finished cigarette pallet to the pallet online device, the latent AGV sends a release application signal. After the electronic control system confirms the release application signal, the latent AGV transports the finished cigarette pallet to the pallet online device, completes the unloading task, and applies to the scheduling system to leave.

6. The whole pallet outbound system according to claim 1, characterized in that: When the warehouse management system detects that the information of a docking station is empty and determines that the current delivery quantity does not meet the order requirements, it immediately generates a new outbound task and sends it to the scheduling system, and issues a scheduling instruction to the latent AGV system to schedule the idle latent AGV to perform the picking task and add the finished product pallets to the docking station with empty information.

7. A method for removing a whole pallet from storage, characterized in that: Including the finished product pallet outbound process, including: Outbound from the outbound buffer area: The latent AGV goes to the designated cargo location in the outbound buffer area to pick up the corresponding finished product pallet, and transports it to the pallet loading device. The finished product pallet is lifted to the same height as the outbound conveyor line by the pallet loading device, and then transported to the film wrapping station of the film wrapping machine via the outbound conveyor line. After the finished product pallet is film wrapped, it is transported to the shipping area via the corridor pallet conveyor line, and the whole pallet is loaded and shipped; Cross-floor delivery: The lurking AGV goes to the designated cargo location on the target floor to pick up the corresponding finished product pallet, descends to the delivery floor via the elevator, and delivers it to the three docking stations on the same floor for temporary storage of the finished product pallets. The lurking AGV moves the finished product pallet from the docking station to the pallet loading device. The finished product pallet is lifted to the same height as the delivery conveyor line by the pallet loading device, and is transported to the wrapping station of the wrapping machine via the delivery conveyor line.
