Description

Technical Field

[0001] The present invention relates to the field of logistics monitoring technology, and more specifically, to a cross-floor warehousing system and method. Background Art

[0002] The automatic storage system for finished products in the tobacco industry is an example of the application of modern logistics and warehousing technology to a specific industry, aiming to improve storage efficiency, reduce labor costs and ensure the accuracy of operations. At present, the industry mainly adopts two forms of automatic storage systems: automated stereoscopic warehouses and flat warehouses. The automated stereoscopic warehouse consists of key structures such as multi-layer shelves, aisle stackers (or four-way shuttles), and storage workbenches. The system can realize the automation of finished product storage, is easy to operate, and greatly improves the efficiency of storage and retrieval. The flat warehouse uses single-layer shelves and is equipped with AGV (automatic guided vehicles) for automatic storage of goods. AGV does not need to carry goods up and down the stairs, which simplifies the operation process.

[0003] However, when adding such systems to existing multi-story finished product warehouses, a lot of structural modifications are required to accommodate the running tracks of stackers or shuttles and the installation requirements of shelves. In multi-story warehouses, since AGVs cannot go up and down directly, flat warehouses are not suitable for multi-story storage needs. Summary of the invention

[0004] One object of the present invention is to provide a cross-floor warehousing system and method to solve the aforementioned problems of requiring a large amount of structural modification to adapt to the running tracks of stackers or shuttles and the installation requirements of shelves, and the flat warehouse equipped with AGV is not suitable for multi-layer storage requirements.

[0005] According to a first aspect of the present invention, a cross-floor warehousing system is provided, comprising an automatic conveying device and a palletizing warehousing device, wherein:

[0006] The automatic conveying device comprises a storage conveying line, a barcode recognition device, a cigarette piece sorting system and a stacking robot. The storage conveying line is provided with a barcode recognition device for performing barcode recognition on finished cigarette pieces, conveying finished cigarette pieces with qualified barcode recognition to the cigarette piece sorting system, and conveying finished cigarette pieces with unqualified barcode recognition to a rejection port; the cigarette piece sorting system sorts the cigarette pieces after the barcode is read to the cigarette piece buffer channel, and the cigarette pieces in the cigarette piece buffer channel are stacked by the stacking robot;

[0007] The palletizing and warehousing device includes a palletizing robot and a cross-floor transport device. The palletizing robot is used to grab cigarette pieces and stack them on pallets according to the specified stack shape and quantity to perform palletizing of cigarette pieces; the cross-floor transport device is used to receive pallets of cigarette pieces and transport the pallets of cigarette pieces to designated cargo locations for storage and stack the pallets of cigarette pieces.

[0008] Optionally, the cross-floor transport device comprises:

[0012] A fork-type AGV is used to transport the cigarette pallets at the docking station in the storage area to the designated storage location for storage and to stack the cigarette pallets;

[0013] The latent AGV, the vertical lift, and the fork-type AGV exchange data via a wireless communication network.

[0014] Optionally, the cross-floor warehousing system further comprises corridor equipment, and the corridor equipment is used to convey the finished cigarette pieces delivered by the case filling and sealing unit into the cigarette piece warehousing conveyor line.

[0015] Optionally, the barcode recognition device reads the No. 1 engineering code of the cigarette or the quality traceability code of the work-in-progress according to the unit association method.

[0016] Optionally, the palletizing and warehousing device also includes an information binding module and a cargo location allocation module, the information binding module is used to automatically bind the pallet barcode or the pallet RFID ID number with the cigarette piece No. 1 engineering code or quality traceability code; the cargo location allocation module allocates the actual pallet storage location for the cigarette piece according to the pallet and cigarette piece information bound by the information binding module.

[0017] Optionally, the palletizing warehousing device also includes a pallet code divider. After the palletizing station information is empty, the pallet code divider splits the empty pallet group into single empty pallets, and the latent AGV transports the single empty pallets split by the pallet code divider to supplement the idle palletizing station.

[0018] Optionally, the cross-floor warehousing system further comprises a palletizing process layout device, and the palletizing process layout device comprises a first palletizing robot and a second palletizing robot;

[0019] The first palletizing robot performs palletizing operations corresponding to three palletizing stations, one paper slide tray supply station, one depalletizing station and four conditional smoke buffer channels;

[0020] The second palletizing robot performs palletizing operations corresponding to three palletizing stations, one paper slide tray supply station and three conditional smoke buffer channels.

[0021] Optionally, the cigarette cache channel is provided with a cache quantity monitoring sensor, which is configured as an infrared sensor or an ultrasonic sensor. The cache quantity monitoring sensor monitors and measures the number of cigarette pieces piled up and the volume of the space occupied in the cigarette cache channel, and sends a palletizing start signal to the palletizing robot when the cache quantity reaches a preset threshold.

[0022] According to a second aspect of the present invention, a cross-floor warehousing method is provided, comprising the following steps:

[0023] The finished cigarettes sent out by the packing and sealing unit are transported to the cigarette storage conveyor line through the corridor equipment. They are identified by barcodes on the cigarette storage conveyor line. The finished cigarettes that pass the barcode identification are transported to the cigarette sorting system by the cigarette storage conveyor line. The cigarettes that fail the barcode identification flow to the rejection port and are manually rejected.

[0024] The cigarette case sorting system sorts the cigarette cases after the codes are read to a designated cigarette case buffer channel, and the cigarette cases in the cigarette case buffer channel are palletized by the palletizing robot;

[0025] The lurking AGV goes to the palletizing station to pick up the piece-and-smoke pallet, sends it to the vertical elevator car on that floor, and is lifted to the corresponding floor by the vertical elevator, and then sent to the corresponding storage area docking platform on the corresponding floor. The fork-type AGV moves it to the designated cargo location for storage and stacks the piece-and-smoke pallets.

[0026] Optionally, the cross-floor warehousing method also includes:

[0027] After the cigarette pallet is moved away, the palletizing station information is empty. Get the pallet number at the bottom of the pallet code extension and initiate an application to move the empty pallet into the station.

[0028] The latent AGV transports the single empty pallet disassembled by the pallet stacking machine to the vacant palletizing station. After the task is completed, the pallet information is written to the palletizing station.

[0029] The cross-floor warehousing system and method disclosed in the present invention have the following technical effects:

[0030] After the finished cigarettes enter the storage conveyor line, the barcode recognition device reads the relevant code, and the electronic control system compares the recognized brand information with the virtual platform information. The inconsistent ones enter the manual rejection port for processing. The electronic control system controls the cigarette sorting line to distribute the cigarettes to the corresponding cigarette cache channel based on the read information, achieving more precise and accurate sorting.

[0031] The scheduling method based on distance and equipment idle status realizes the optimal utilization of AGV resources, avoiding the situation where some equipment is idle and some tasks are piled up due to disorderly calling of AGV equipment. It can quickly respond to pickup needs, shorten the waiting time for goods to be transported, and improve the overall logistics turnover speed.

[0032] For cross-floor storage, the collaborative operation of equipment such as lurking AGV, vertical hoist, and fork-type AGV enables efficient transfer of cigarettes from the palletizing station to storage areas on different floors. The lurking AGV is responsible for taking pallets from the palletizing station and can move flexibly in the plane area to deliver the pallets to the vertical hoist cabin. The vertical hoist enables rapid transportation between floors, and the fork-type AGV performs precise handling and stacking operations on the corresponding floors. Different equipment play their respective advantages to jointly ensure the smooth progress of the cross-floor storage process and improve the overall warehousing and logistics efficiency.

[0044] 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.

[0045] The present invention proposes an embodiment of a cross-floor warehousing system. Specifically, Figure 1 As shown, it includes automatic conveying device and palletizing storage device, among which:

[0046] The automatic conveying device includes a storage conveying line, a barcode recognition device 2, a cigarette piece sorting system 3 and a stacking robot 5. The storage conveying line is provided with a barcode recognition device 2 for barcode recognition of finished cigarette pieces, and the finished cigarette pieces with qualified barcode recognition are conveyed to the cigarette piece sorting system 3, and the finished cigarette pieces with unqualified barcode recognition are conveyed to the rejection port for manual rejection. The cigarette piece sorting system 3 sorts the cigarette pieces after the barcode is read to the cigarette piece buffer channel 4, and the cigarette pieces in the cigarette piece buffer channel 4 are stacked by the stacking robot 5.

[0047] The palletizing and warehousing device includes a palletizing robot 5 and a cross-floor transport device. The palletizing robot 5 is used to grab cigarettes and stack them on pallets according to the specified stack shape and quantity to perform palletizing of cigarettes; the cross-floor transport device is used to receive pallets of cigarettes and transport them to designated cargo locations for storage and stack them. The close cooperation of automated transportation, barcode recognition, sorting, palletizing and cross-floor transport significantly improves the efficiency of warehouse warehousing operations. The use of the cross-floor transport device enables warehouses on different floors to form a whole, achieving maximum utilization of resources and optimal management of warehouse space.

[0048] In an embodiment of the present invention, the cross-floor transport device comprises:

[0049] Lurking AGV7 is used to move the solid pallet to the palletizing station 10, or directly deliver it to the single-layer area storage on the corresponding floor. Among them, the lurking AGV7 is equipped with laser navigation, electromagnetic navigation or visual navigation devices, which can accurately locate and avoid obstacles. In addition, they also have functions such as automatic charging, fault diagnosis and remote monitoring to ensure continuous and stable operation.

[0050] The vertical lift 8 is used to receive the pallet of cigarettes delivered by the latent AGV 7 and lift it to the corresponding floor; the vertical lift 8 is equipped with a precision control system that can accurately control the lifting speed, position and safety protection devices to ensure the stability and safety of the pallet during the lifting process.

[0051] The storage area docking station is used to receive the pallets of cigarettes lifted by the vertical lift 8; the storage area docking station is the transition area between the vertical lift 8 and the fork-type AGV, and is used to receive the pallets lifted by the vertical lift 8 and prepare to pass them to the fork-type AGV for subsequent handling. The storage area docking station is equipped with a buffer area and a guide device to ensure that the pallets can be transferred from the vertical lift 8 to the fork-type AGV smoothly and accurately. The storage area docking station is also equipped with a pallet identification system to verify the pallet information and ensure the accuracy of handling.

[0052] Fork-type AGV is used to move pallets from the storage area docking station to the designated storage location for storage and stack the pallets; the fork-type AGV uses the fork arm to pick up the pallet and then move it to the designated storage location for storage

[0053] The latent AGV 7, vertical lift 8, and fork-type AGV exchange data through a wireless communication network (Wi-Fi, Zigbee, LoRa and other wireless communication technologies), achieving seamless connection and efficient communication between devices, and improving the automation and intelligence level of the entire logistics system.

[0054] In an embodiment of the present invention, the cross-floor storage system also includes a corridor device, which is used to transport the finished cigarette pieces sent out by the box packing unit into the cigarette piece storage conveyor line 1. A conveying speed regulating device is also installed on the corridor device, which can automatically adjust the conveying speed according to the conveying flow rate of the finished cigarette pieces. The conveying speed regulating device includes a flow sensor, an intelligent control unit and a variable speed drive system. The flow sensor monitors the flow of the finished cigarette pieces on the conveyor belt of the corridor device in real time. The intelligent control unit receives the conveying flow information collected from the flow sensor, quickly starts the internal algorithm for analysis and processing, generates a speed adjustment instruction, and the variable speed drive system adjusts the running speed of the conveyor belt according to the speed adjustment instruction.

[0055] In an embodiment of the present invention, the barcode recognition device 2 reads the No. 1 engineering code of the cigarette or the quality traceability code of the product in accordance with the unit association method. Among them, the "No. 1 engineering code of the cigarette" is a coding system used by the tobacco industry to identify and manage each finished cigarette. Through this code, many key information such as the production batch, origin, and production date of the cigarette can be traced back; the "quality traceability code of the product" focuses on the quality information traceability of the unfinished product (product) in the tobacco production process, and can record the relevant data of the product in each production process. By reading the barcode in accordance with the unit association method, whether it is the No. 1 engineering code of the cigarette or the quality traceability code of the product, the product quality information can be accurately linked to the unit and process in the production process. Once a quality problem occurs, the unit, process, and related production conditions (such as equipment parameters, implementation of operating specifications, etc.) where the problem occurs can be quickly locked, so that corrective measures can be taken in time to improve the stability and reliability of product quality.

[0056] In the embodiment of the present invention, the palletizing robot 5 grabs the cigarettes and places them on the pallet according to the specified pallet shape (20 pieces, 24 pieces, 30 pieces, 40 pieces) and quantity to perform pallet palletizing. The palletizing storage device also includes an information binding module and a cargo location allocation module. The information binding module is used to automatically bind the pallet barcode or pallet RFID ID number with the cigarette No. 1 engineering code or quality traceability code; the cargo location allocation module allocates the cigarette pallet storage location according to the pallet and cigarette information bound by the information binding module.

[0057] In an embodiment of the present invention, the palletizing warehousing device also includes a pallet code divider 6. After the palletizing platform information is empty, the pallet code divider 6 splits the empty pallet group 9 into single empty pallets, and the latent AGV 7 transports the single empty pallets disassembled by the pallet code divider 6 to supplement the idle palletizing station 10.

[0058] In the embodiment of the present invention, the cross-floor warehousing system further includes a palletizing process layout device, and the palletizing process layout device includes a first palletizing robot 5 and a second palletizing robot 5;

[0059] Among them, the first palletizing robot 5 performs palletizing operations corresponding to 3 palletizing stations 10, 1 paper slide tray supply station, 1 depalletizing station and 4 conditional smoke buffer channels 4;

[0060] The second palletizing robot 5 performs palletizing operations corresponding to three palletizing stations 10, one paper slide tray supply station and three conditional cigarette buffer channels 4. It should be noted that the two palletizing robots 5 can work in parallel and process cigarettes from different sources or with different requirements at the same time. Through the coordination and cooperation between multiple palletizing stations 10, buffer channels and robots, the palletizing processing capacity of the entire cross-floor warehousing system is significantly improved, and it can adapt to larger production scales and complex production scheduling requirements. The different numbers of buffer channels and corresponding station layouts enable the system to flexibly respond to fluctuations in the supply of cigarettes on the production line and the palletizing requirements of different products.

[0061] In the embodiment of the present invention, the cigarette cache channel 4 is provided with a cache quantity monitoring sensor, which is configured as an infrared sensor or an ultrasonic sensor. The cache quantity monitoring sensor monitors and measures the number of cigarettes piled up and the space volume occupied in the cigarette cache channel 4, and sends a palletizing start signal to the palletizing robot 5 when the cache quantity reaches a preset threshold. The threshold is determined based on multiple factors such as the working efficiency of the palletizing robot 5, the capacity of the subsequent storage link, and the smoothness of the entire warehousing process.

[0062] The present invention also provides an embodiment of a cross-floor storage method, specifically as follows Figure 2 As shown, the following steps are included:

[0063] The finished cigarettes sent out by the packing and sealing unit are transported to the cigarette storage conveyor line 1 through the corridor equipment. They are identified by barcodes on the cigarette storage conveyor line 1. The finished cigarettes that pass the barcode identification are transported to the cigarette storage conveyor line 1 to the cigarette sorting system 3. The cigarettes that fail the barcode identification flow to the rejection port and are manually rejected.

[0064] The cigarette case sorting system 3 sorts the cigarette cases after reading the codes to the designated cigarette case buffer channel 4, and the cigarette cases in the cigarette case buffer channel 4 are palletized by the palletizing robot 5;

[0065] The lurking AGV 7 goes to the palletizing station 10 to pick up the piece-sized cigarette pallet, sends it to the vertical hoist 8 cabin on that floor, and is lifted to the corresponding floor by the vertical hoist 8, and is sent to the corresponding storage area docking platform on the corresponding floor, where it is transported to the designated cargo location for storage and stacked by the fork-type AGV.

[0066] It should be noted that the structure, execution process and other contents between the above-mentioned methods are based on the same concept as the system embodiment of the present application, and are methods corresponding to the above-mentioned cross-floor warehousing system. All implementation structures in the above-mentioned system embodiment are applicable to the embodiment of the method. Its specific functions and technical effects brought about can be found in the system embodiment part, which will not be repeated here.

[0067] In another embodiment of the cross-floor warehousing method provided by the present invention, as Figure 3 As shown, the following steps are included:

[0068] (1) The warehouse management system issues brand task information to each cigarette cache channel 4. After receiving the information, the electronic control system stores it in the virtual platform. The finished cigarette pieces are transported to the cigarette storage conveyor line 1 through the corridor equipment. The barcode recognition device 2 reads the cigarette No. 1 engineering code or the work-in-progress quality traceability code. The electronic control system compares the recognized brand information with the virtual platform information. If the brand information is inconsistent, it will enter the manual rejection port for processing. If it is consistent, it will enter the barcode sorting line. After the second barcode recognition, the electronic control system controls the cigarette sorting line to distribute the cigarette pieces to the corresponding cigarette cache channel 4 according to the read information. Then the electronic control system sends the palletizing task to the stacking robot 5. The stacking robot 5 picks up the cigarette pieces at the end of the cigarette cache channel 4 for palletizing according to the pre-set rules. The palletizing rules are preset according to the actual warehouse layout, pallet load and other factors to ensure the standardization and efficiency of the palletizing process and provide neat and standardized cargo units for subsequent handling, storage and other links.

[0069] (2) After any palletizing station 10 completes palletizing, the electronic control system sends a warehousing application to the warehouse management system. The warehouse management system generates a warehousing task (including the palletizing station 10 to pick up the goods, the target floor and aisle entrance for warehousing, etc.) and sends it to the dispatching system. The dispatching system issues an instruction to the latent AGV7 system, notifying it to go to the palletizing station 10 to pick up the solid pallet. After receiving the instruction, the latent AGV7 system dispatches the nearest idle AGV to perform the picking task. This scheduling method based on distance and equipment idle status achieves optimal utilization of AGV resources.

[0070] (3) The lurking AGV 7 goes to the task point according to the pre-planned route. Before entering the palletizing station 10 to receive the goods, it sends an entry application to the dispatching system in advance. After confirmation by the dispatching system, the lurking AGV 7 is allowed to enter the palletizing station 10 to pick up the goods. Through advance communication and coordination, the dispatching system can better grasp the location and task progress of each AGV, which is convenient for the precise control of the overall logistics dispatch.

[0071] (4) After the latent AGV7 takes the pallet, it sends a signal to the dispatching system to apply for departure. After the dispatching system allows it, it leaves according to the pre-set route to prevent the latent AGV7 from leaving at will and causing blockage in the logistics channel or interference with other running equipment;

[0072] (5) When the latent AGV7 moves to the elevator 8 with cargo, it sends an entry application signal to the elevator 8 system and informs the target floor. After the elevator 8 system allows it, it opens the fast lifting shutter door and the latent AGV7 enters the elevator 8. The elevator 8 moves to the target floor. The latent AGV7 sends a departure application signal to the elevator 8 system. The elevator 8 system confirms that the equipment is in place and allows the latent AGV7 to leave. This type of risk is avoided through the application and confirmation mechanism. At the same time, it ensures that the cargo can smoothly enter the elevator 8 for transfer between floors, thereby improving the efficiency of cross-floor transportation.

[0073] (6) The lurking AGV7 moves to the target aisle entrance with the cargo and applies to the warehouse management system. The warehouse management system informs it of the specific cargo location. The lurking AGV7 applies to the dispatching system to enter the target cargo location. After the dispatching system confirms, the lurking AGV7 enters the cargo location to perform the unloading task, and then applies to the dispatching system to leave. Through multi-level information interaction and application confirmation, the precise positioning of AGV unloading is achieved;

[0074] (7) Process of replenishing empty pallets at the palletizing station: After the latent AGV7 transports the finished product pallet from the palletizing station, the electronic control system checks that the information of the palletizing station is empty, obtains the bottom pallet number of the pallet code extension 6, and initiates an application for the station to move the empty pallet. The warehouse management system issues a transport task, and the latent AGV7 transports the single empty pallet removed by the pallet code extension 6 to the idle palletizing station 10. After the task is completed, the scheduling system writes the pallet information to the palletizing station. This real-time monitoring mechanism ensures that the palletizing station will not stagnate due to lack of pallets, and maintains the continuity of the palletizing operation. It realizes the accurate replenishment of empty pallets and updates the relevant information, which facilitates the subsequent management system to accurately grasp the use of pallets at each station.

[0075] (8) Process of replenishing empty pallet group 9 by pallet code extension 6: After the electronic control system detects that the information of pallet code extension 6 is empty, it initiates an application to replenish empty pallet group 9 to the warehouse management system, and the warehouse management system issues a task to pallet code extension 6. The electronic control system applies for empty pallet group 9 to be shipped out of the empty pallet temporary storage area, and the warehouse management system generates a task for empty pallet group 9 and issues it to the latent AGV7 system. The latent AGV7 system dispatches the nearest idle latent AGV7 to transport empty pallet group 9 from the empty pallet temporary storage area and delivers it to pallet code extension 6. Pallet code extension 6 splits empty pallet group 9 into individual empty pallets. Through the collaborative work of multiple systems, efficient transportation and reasonable splitting of empty pallets from the temporary storage area to pallet code extension 6 are achieved, ensuring that pallet code extension 6 can replenish empty pallet group 9 on demand, avoiding interruption of subsequent palletizing and other operation processes due to insufficient pallet supply, and maintaining the stability of pallet supply in the entire warehousing system.

[0076] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
