Description

Technical Field

[0001] The present application relates to the field of logistics, and in particular to a cigarette production logistics system based on a latent AGV. Background Art

[0002] With the advancement of logistics technology, industrial latent automated guided vehicle (AGV) technology is becoming increasingly mature. Compared with conventional laser AGVs, latent AGVs have the advantages of low investment, convenient maintenance, and higher flexibility. Some cigarette manufacturers have begun to explore the introduction of latent AGV systems into cigarette production logistics systems based on actual needs.

[0003] However, with current technology, due to the need for logistics connection and the inherent characteristics of latent AGVs, they must be used in conjunction with mobile racks to perform logistics transfer operations. In actual operation, the mobile racks loaded with goods are placed in the storage area. The latent AGVs then travel to the storage area to connect with the mobile racks loaded with goods. They then deliver the goods loaded on the mobile racks to the required location. After the goods loaded on the mobile racks are used, the mobile racks are returned to the storage system.

[0004] If there are ten locations that need to use ten different kinds of goods, then ten AGVs are needed to transfer the ten mobile shelves containing the corresponding goods to the corresponding ten locations. Therefore, when transporting the goods to the required locations, the required movement distance of the AGV is very cumbersome and lengthy, which indirectly leads to the extremely large number of AGVs required, low AGV utilization efficiency, and high costs. Summary of the Invention

[0005] The purpose of this application is to provide a cigarette production logistics system based on latent AGV to solve the above problems. By setting up a conveyor, the path of the AGV when carrying goods can be simplified, the number of AGVs required can be reduced, the utilization efficiency of the AGV can be improved, and costs can be saved.

[0006] The present application provides a cigarette production logistics system based on a latent AGV, including a storage system, a pallet, a diversion system, and a first AGV; the storage system includes multiple groups of parallel shelves; the diversion system includes an infeed conveyor, a first linear shuttle, and a diversion conveyor; the infeed conveyor and the diversion conveyor are respectively arranged on both sides of the first linear shuttle, the infeed conveyor and the diversion conveyor respectively run in a first direction, and the first linear shuttle runs in a second direction, and the first direction and the second direction are perpendicular; the first AGV is used to transport pallets loaded with goods from the shelves to the infeed conveyor; the infeed conveyor is used to transport pallets loaded with goods to the diversion conveyor via the first linear shuttle; the diversion conveyor is used to transport the goods in the pallet to the required location.

[0007] This embodiment provides a cigarette production logistics system based on a latent AGV. After the first AGV transports the goods on the shelf to the diversion system via a pallet, the goods first arrive at the feed conveyor of the diversion system. Since the running direction of the first straight shuttle is perpendicular to the running direction of the diversion conveyor, the feed conveyor can transport the goods to each diversion conveyor via the first straight shuttle, and each diversion conveyor can transport the goods to each required location. Therefore, the first AGV does not need to deliver the goods to each required location separately, but only needs to transport the pallet loaded with goods to the diversion system location, shortening the moving distance of the first AGV. Because the running distance of the first AGV is shortened, the number of goods that the first AGV can transfer in the same time increases, so the number of first AGVs required for the entire cigarette production logistics system based on the latent AGV is reduced. The utilization rate of the first AGV is improved and costs are saved.

[0008] In an optional embodiment, when the cigarette production logistics system based on the latent AGV is used to transport single-item cigarette accessories, the cigarette production logistics system based on the latent AGV also includes a second AGV, a third AGV and a receiving system, and the receiving system includes a receiving chain conveyor, an electronic tag machine (radio frequency identification, RFID) and a first pallet depalletizer; the first pallet depalletizer and RFID are respectively arranged on the receiving chain conveyor; the second AGV is used to transport multiple stacked pallets to the receiving chain conveyor; the first pallet depalletizer is used to separate a pallet from multiple stacked pallets; the receiving chain conveyor is used to transport the separated pallet, and in the process of the receiving chain conveyor transmitting the pallet, the pallet is loaded with goods, and then the RFID writes the identity document (ID) to the bottom of the pallet; the third AGV is used to transport the pallet loaded with goods from the receiving chain conveyor to the shelf; the shelf, the feeding conveyor and the diversion conveyor are respectively provided with verification equipment for verifying the ID.

[0015] In this implementation, because the materials used to bundle individual cigarette accessories are considered unusable when transporting them, they must be separated from the accessories. Therefore, a debris bin and debris conveyor are provided. The debris sorted by the palletizing robot is placed in the bin and then transported to other locations via the debris conveyor. Meanwhile, the goods required for processing, namely individual cigarette accessories, can be sorted into standard trays and then transported to the required workstations, thereby increasing processing efficiency.

This recycling system allows the first AGV to quickly return empty and stacked pallets to the storage system. Because the first AGV can transport a large number of stacked, empty pallets to the storage system at once, the first AGV's idle travel time is shortened, improving its utilization rate. Furthermore, the recycling system can also transport unused single-item cigarette accessories to the storage system for future use, saving resources and reducing waste.

DETAILED DESCRIPTION

[0032] The following describes embodiments of the present application in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0033] Please refer to Figures 1 to 8 The present application provides a cigarette production logistics system based on a latent AGV, including a storage system 10, a pallet 20, a diversion system 30, and a first AGV; the storage system 10 includes multiple groups of parallel shelves 11; the diversion system 30 includes an infeed conveyor 31, a first linear shuttle 32, and a diversion conveyor 33; the infeed conveyor 31 and the diversion conveyor 33 are respectively arranged on both sides of the first linear shuttle 32, the infeed conveyor 31 and the diversion conveyor 33 respectively run in a first direction, and the first linear shuttle 32 runs in a second direction, and the first direction and the second direction are perpendicular; the first AGV 40 is used to transport the pallet 20 loaded with goods 100 from the shelf 11 to the infeed conveyor 31; the infeed conveyor 31 is used to transport the pallet 20 loaded with goods 100 via the first linear shuttle 32 to the diversion conveyor 33; the diversion conveyor 33 is used to transport the goods 100 in the pallet 20 to the required location.

[0034] This embodiment provides a cigarette production logistics system based on a latent AGV. After the first AGV 40 transports the goods 100 on the shelf 11 to the diversion system 30 via the pallet 20, the goods 100 first arrive at the infeed conveyor 31 of the diversion system 30. Since the running direction of the first straight shuttle 32 is perpendicular to the running direction of the diversion conveyor 33, the infeed conveyor 31 can transport the goods 100 to each diversion conveyor 33 via the first straight shuttle 32, and each diversion conveyor 33 can transport the goods 100 to each required location.

[0035] As a result, the first AGV 40 does not need to deliver the goods 100 to each required location separately. It only needs to transport the pallet 20 containing the goods 100 to the location of the diversion system 30, which shortens the movement distance of the first AGV 40. Because the operation distance of the first AGV 40 is shortened, the number of goods 100 that can be transferred by the first AGV 40 in the same time period increases, so the number of first AGVs 40 required for the entire cigarette production logistics system relying on the latent AGV is reduced. The utilization rate of the first AGV 40 is improved and costs are saved. The reduction in the number of first AGV 40 carts also reduces the risk of collisions during the operation of multiple first AGV 40 carts, increasing the safety factor.

[0036] In addition, the infeed conveyor 31, the first linear shuttle 32 and the diversion conveyor 33 all have fixed tracks, so the control procedure is relatively simple, thereby simplifying the control difficulty.

[0037] In an optional embodiment, when the cigarette production logistics system based on the latent AGV is used to transport single-item cigarette accessories, the cigarette production logistics system based on the latent AGV also includes a second AGV50, a third AGV60 and a receiving system 70. The receiving system 70 includes a receiving chain conveyor 71, an electronic tag machine (radio frequency identification, RFID) 711 and a first pallet dismantling machine 72; the first pallet dismantling machine 72 and the RFID711 are respectively arranged on the receiving chain conveyor 71.

[0038] The second AGV50 is used to transport multiple stacked pallets 20 to the receiving chain conveyor 71; the first pallet dismantling machine 72 is used to separate a pallet 20 from the multiple stacked pallets 20; the receiving chain conveyor 71 is used to transport the separated pallet 20, and in the process of the receiving chain conveyor 71 transmitting the pallet 20, the pallet 20 is loaded with goods 100, and then the RFID711 writes the identity document (ID) information into the bottom of the pallet 20.

[0039] The third AGV 60 is used to transport the pallet 20 loaded with goods 100 from the receiving chain conveyor 71 to the shelf 11; the shelf 11, the infeed conveyor 31 and the diversion conveyor 33 are respectively provided with a verification device 110 for verifying the ID.

[0040] In this embodiment, the second AGV 50, third AGV 60, and receiving system 70 are used to store individual cigarette excipients in the storage system 10 during the tobacco product processing process for subsequent processing. In this structure, because the pallets 20 can be stacked, the space required to store empty pallets 20 is reduced, saving a significant amount of space.

The pallet conveyor 74 is used to transport the separated pallet 20 to the loading conveyor 76 via the receiving straight shuttle 73. Goods 100 are placed on the pallet 20 on the loading conveyor 76. The loading conveyor 76 then transports the pallet 20 loaded with goods 100 via the receiving straight shuttle 73 to the finished product conveyor 75. While the finished product conveyor 75 is transporting the pallet 20 loaded with goods 100, the RFID 711 writes the ID to the bottom of the pallet 20.

[0043] The third AGV 60 is used to transport pallets 20 loaded with goods 100 to shelves 11.

The pallet-matching robot 34 is configured to sort the goods 100 from pallets 20 onto the finished product conveyor belt 35, which then transports the goods 100 to the desired location. In this embodiment, the pallet-matching robot 34 directly sorts the finished cigarettes from the pallets 20 onto the finished product conveyor belt, which then transports them. This allows the finished cigarettes to be quickly transported to the desired location, improving transport efficiency.

[0048] In this embodiment, because the materials used to bundle individual cigarette accessories are considered unusable during transportation and need to be separated from the accessories, a debris bin 36 and debris conveyor 37 are provided. The debris sorted by the tray-picking robot 34 is placed in the debris bin 36 and then transported to other locations via the debris conveyor 37. The goods 100 required for processing, namely individual cigarette accessories, can be sorted into standard trays 38 and then transported to the required workstations, thereby increasing processing efficiency.

[0049] In an optional embodiment, when the cigarette production logistics system based on the latent AGV is used to transport single-item cigarette accessories, the diversion system 30 also includes a second straight shuttle 310, a second tray dismantling machine 311 and a standard conveyor 312; the second straight shuttle 310 and the first straight shuttle 32 are arranged in parallel and run in the second direction; the standard conveyor 312 runs in the first direction; the standard conveyor 312 is arranged on the side of the second straight shuttle 310 away from the first straight shuttle 32; the second tray dismantling machine 311 is arranged on the standard conveyor 312, and is used to split a standard tray 38 from multiple stacked standard trays 38, and the standard conveyor 312 is used to transport the split standard tray 38 to the docking conveyor 39 via the second straight shuttle 310.

The standard trays 38 are sourced as follows: Standard trays 38 are pre-stacked on the standard conveyor 312. The second tray unpacker 311 on the standard conveyor 312 unpacks a standard tray 38 from the stacked trays. The standard conveyor 312 then transports the unpacked trays 38 to the docking conveyor 39 via the second straight shuttle 310. The debris is items such as packaging boxes.

[0068] It should be emphasized that the pallets 20 from which the auxiliary materials have been sorted are transported by the diversion conveyor 33 via the first linear shuttle 32 to the recycling conveyor 90, where they are stacked by the palletizer 91 on the recycling conveyor 90. When the pallets 20 from which the auxiliary materials have been sorted are stacked to a certain height, the first AGV 40 transports the stacked pallets 20 to the shelves 11 of the storage system 10 for future use.

[0069] The pallet 20 with remaining auxiliary materials is transported by the diversion conveyor 33 to the residual material recovery conveyor 90 via the first straight shuttle 32, and then the first AGV 40 transports the pallet 20 with unsorted auxiliary materials from the residual material recovery conveyor 90 to the shelf 11.

[0070] Next, the docking conveyor 39 transports the standard tray 38 filled with auxiliary materials via the second straight shuttle 310 to the delivery conveyor 80. The delivery conveyor 80 transports the standard tray 38 filled with auxiliary materials to the desired location. While the delivery conveyor 80 is transporting the standard tray 38 filled with auxiliary materials, the coding machine 81 writes the ID on the bottom of the standard tray 38 filled with auxiliary materials.

[0071] During the entire transportation process, the shelf 11, the feeding conveyor 31 and the diversion conveyor 33 are respectively provided with a verification device 110 for verifying the ID. When passing the relevant position, the verification device 110 will verify the ID at the bottom of the pallet 20 to ensure the accuracy of the transportation of auxiliary materials.

[0072] In addition, it should be noted that after the standard tray 38 filled with auxiliary materials is transported to the required workstation, if the auxiliary materials in the standard tray 38 are used up, the empty standard tray 38 is transported to the standard conveyor to realize the recycling of the standard tray 38 between the diversion system 30 and the workstation.

[0073] Of course, the entire process described above is controlled by instructions issued by the electronic control system.
