[0026] This invention provides an intelligent manufacturing and logistics system, please refer to... Figure 1 An embodiment of the intelligent manufacturing and logistics system includes an assembly line 11, a warehouse 13, a production line area 15, a first conveyor device, a second conveyor device 19, and a control module. The assembly line 11 has a first workstation OP02 and a second workstation OP11. A checkpoint detection device (not shown) is installed at the first workstation OP02 to detect whether the main body of the equipment has reached the first workstation OP02. The second workstation OP11 is used to assemble product A onto the main body of the equipment. The warehouse 13 stores materials for assembling product A. The production line area 15 is used to assemble product A. The first conveyor device transports materials from the warehouse 13 to the production line area 15 for assembly. The second conveyor device 19 transports the assembled product A from the production line area 15 to the second workstation OP11. The control module starts retrieving parts from the warehouse 13 to assemble product A when the checkpoint detection device detects that the main body of the equipment has reached the first workstation OP02. The total production time of product A is matched with the main line assembly time from the first workstation OP02 to the second workstation OP11. The total production time of product A refers to the total time from the time the parts of product A leave the warehouse to the time it is assembled on the main line. The main line assembly time from the first station OP02 to the second station OP11 refers to the total time from when the main body of the equipment arrives at the first station OP02, during assembly at the first station OP02, to when it arrives at the second station OP11.

[0027] In the intelligent manufacturing and logistics system of this embodiment, based on the material call at the assembly line, the logistics can be automatically and on demand to carry out logistics outbound and production, which greatly reduces the inventory of intermediate products, shortens the logistics lead time, avoids products not being supplied in time, avoids product waiting, improves production efficiency, and thus achieves efficient production scheduling to adapt to the production rhythm of the assembly line.

[0028] In this embodiment, the warehouse 13 and the production line area 15 are located on one side of the main assembly line 11, and the production line area 15 is closer to the main assembly line 11 than the warehouse 13.

[0029] In this embodiment, warehouse 13 can be an automated warehouse, which includes multi-layer racking. Parts (including raw materials) are typically placed on pallets, and the pallets are stored on the racks. First aisles 132 are provided between the racks. Stacker cranes 134 can move, lift, and move back and forth within the first aisles 132 to pick up materials from the racks and transport them to designated locations within warehouse 13. Specifically, in this embodiment, the automated warehouse includes four rows of racks and two first aisles 132. Each first aisle 132 has a row of racks on each side, and each first aisle 132 is equipped with one stacker crane 134. The stacker crane 134 moves only within its corresponding first aisle 132. It is understood that two first aisles 132 may also be equipped with only one stacker crane 134; the number of stacker cranes 134 is mainly determined by the amount of material handling work.

[0030] Specifically, an inbound conveyor line (not shown) is provided on one side of warehouse 13. Materials (such as incoming materials of product A) can be placed on the inbound conveyor line using forklifts, etc., and then transported from the inbound conveyor line to warehouse 13 and placed in designated storage locations by stacker crane 134. Figure 1 In this embodiment, the inbound conveyor line can be located on the left side of warehouse 13. Specifically, the control module includes a WMS (Warehouse Management System), an LCS (Logistic Control System), and a WCS (Warehouse Control System). When materials arrive at the inbound conveyor line, the incoming materials and the mother pallet can be scanned and bound, and the information is transmitted to the WMS system for storage location allocation. The WMS system dispatches the WCS system through the LCS system to send the inbound storage location instruction, and the WCS system dispatches the stacker crane 134 to transport the materials to the designated storage location.

[0031] Specifically, warehouse 13 also includes an outbound transfer station 136 and a return transfer station 137. A stacker crane 134 is used to transport materials requiring outbound processing to the outbound transfer station 136 (typically transporting the materials along with their pallets) for the first conveyor to retrieve. The stacker crane 134 is also used to transport leftover materials returned by the first conveyor to the return transfer station 137 back to warehouse 13 and place them in designated locations. Specifically, the control module also includes a MES (Manufacturing Execution System) and a LES (Logistics Execution System). The MES system sends material requirements to the LES system to generate delivery requests. The LES system sends outbound requests to the WMS system to generate outbound tasks. The WMS system sends outbound tasks to the LCS system, which in turn sends them to the WCS system. The WCS system schedules the stacker crane 134 to transport the materials requiring outbound processing to the outbound transfer station 136. For material tailings, the WMS system generates tailings warehousing tasks and sends them to the WCS system via LCS. The WCS system schedules the first transport device to deliver the material tailings to the return docking station 137 and schedules the stacker crane 134 to move the material tailings to the return storage location assigned by the WMS system.

[0032] In this embodiment, the production line area 15 is configured with a number of production lines based on the demand for product A. In this embodiment, production lines 1 and 2 are used to produce product A. Specifically, in this embodiment, production line area 15 also includes production line 3 for producing product B, and the second workstation OP11 is used to assemble product B onto the main body of the equipment. Here, since the demand for product A assembled at the second workstation OP11 is much greater than the demand for product B, there are more production lines producing product A than producing product B (in one embodiment, the demand for product A is 95%, and the demand for product B is 5%). Production lines 1 and 2 can be automated, while production line 3 can be manual, thus minimizing production costs while meeting assembly requirements. Of course, the number of production lines producing product A and product B, and whether they are automated, can be adjusted according to the demand for product A and product B, and are not limited here. Additionally, if necessary, production line area 15 can also include production line 4 for producing product C, etc. For example, suppose the second workstation OP11 is for assembling the boom of a truck crane. This intelligent manufacturing and logistics system is used to produce 5-section and 4-section truck cranes. The market demand for 5-section truck cranes is much greater than that for 4-section truck cranes. In production line area 15, production lines 1 and 2 can be used to produce 5-section booms, and production line 3 can be used to produce 4-section booms. Of course, the demand for product A may be greater than the demand for product B, or it may be that the number of product A components that need to be assembled on the main body of the equipment is greater than the number of product B components.

[0033] Specifically, production line area 15 also includes a first loading area 151, which is equipped with a loading robot 153. The loading robot 153 is used to grab materials conveyed by the first conveyor (in this embodiment, the loading robot 153 grabs materials from a pallet; after the required materials are grabbed, the pallet may still contain other materials, or it may be empty). The robot 153 also feeds back the grabbed material information to the WCS system, LCS system, WMS system, and CCS system (production line central control system), thereby enabling the WCS system, LCS system, WMS system, and CCS system to update the inventory material quantity in real time. Production line area 15 may also include a second loading area 153, which is used to place materials transported by the first conveyor for producing product B.

[0034] In this embodiment, the first conveying device includes a first conveying mechanism 171, which includes a first connecting part 1711 and a transport part 1713. The first connecting part 1711 connects to the outbound connecting station 136 and the return connecting station 137. The first connecting part 1711 is used to acquire materials from the outbound connecting station 136 and to transport the materials to the return connecting station 137. The transport part 1713 is used to transport materials from the first connecting part 1711 to the first loading area 151 of the production line area 15, and to transport remaining materials (i.e., tail materials) or empty pallets back to the first connecting part 1711. The WCS system is also used to schedule the first conveying mechanism 171 of the first conveying device to transport materials to the first loading area 151 of the production line area 15. Here, the first conveying mechanism 171 is used to transport materials belonging to the manufactured product A.

[0035] Specifically, the first conveying mechanism 171 can be a conveyor line such as a roller conveyor or a chain conveyor. Conveyor lines have high conveying efficiency, but their construction cost is high. Specifically, the first conveying mechanism 171 is used to transport materials needed to produce product A. It is understood that the first conveying mechanism 171 can also be other forms of conveying mechanism, such as an AGV mechanism.

[0036] Specifically, the conveying section 1713 can be a loop structure. When the material to be grabbed is not grabbed in time by the loading robot 153 (for example, there is too much material to be grabbed, and the conveying speed of the conveying section 1713 and the second connecting section 1715 is too fast to grab all the material in time), the material can be recycled once more in the conveying section 1713 and wait to be grabbed next time. In this way, the first conveying mechanism 171 does not need to wait, which can improve the conveying efficiency.

[0037] Specifically, the first conveying device also includes a second conveying mechanism 173, which is used to transport materials from the first conveying mechanism 171 to the second loading area 153 of the production line area 15.

[0038] Specifically, please refer to the following: Figure 2 The second conveying mechanism 173 can be an AGV (Automatic Guided Vehicle) mechanism. Specifically, the second conveying mechanism 173 is used to transport the materials needed to produce product B. It is understood that the first conveying mechanism 171 can also be other forms of conveying mechanism, such as roller conveyors or chain conveyors. In this embodiment, since the demand for product B is relatively small, the corresponding materials required to produce product B are also relatively small. Therefore, an AGV mechanism, which has lower conveying efficiency but is relatively inexpensive and occupies less space, can be used. This minimizes costs and space occupation while meeting production needs. The AGV mechanism may include a track 1731 and an AGV trolley 1733, which travels along the track 1731. Specifically, the control module also includes an RCS system (AGV scheduling system), which is used to schedule the AGV trolley 1733.

[0039] Specifically, the first conveying device further includes an outbound elevator 175 and a return elevator 176. The outbound elevator 175 and the return elevator 176 are located near the first conveying mechanism 171 and on the travel path of the second conveying mechanism 173. The outbound elevator 175 is used to transport materials from the first conveying mechanism 171 to the second conveying mechanism 173, and the return elevator 176 is used to transport materials from the second conveying mechanism 173 to the first conveying mechanism 171. Specifically, the outbound elevator 175 can transfer a pallet from the first conveying mechanism 171 and then descend a certain height, at which point the AGV trolley 1733 rises to carry the pallet. The return elevator 176 can descend a certain height, the AGV trolley 1733 descends to place the pallet on the chain of the return elevator 176, the return elevator 176 rises a certain height, and then transfers the pallet to the first conveying mechanism 171.

[0040] Specifically, the first conveying mechanism 171 is located on one side of the warehouse 13 and the production line area 15. Figure 1 In the embodiment, the second conveying mechanism 173 extends from the side of the first conveying mechanism 171 away from the warehouse 13 to the side of the production line area 15 away from the warehouse 13.

[0041] In this embodiment, the second conveying device 19 may be an overhead conveyor line. Specifically, the second conveying device 19 may include two elevators and an overhead roller bed. First, the elevators lift product A or product B to the overhead roller bed, and the overhead roller bed transports product A or product B to the corresponding second workstation OP11. Then, the elevators lower product A or product B to the second workstation OP11 for assembly.

[0042] In this embodiment, please refer to the following: Figure 3The intelligent manufacturing and logistics system also includes an empty pallet stacking machine 21. The empty pallet stacking machine 21 is used to stack pallets whose materials have been removed (in this embodiment, 7 empty pallets are stacked together). The empty pallet stacking machine 21 receives individual empty pallets transported by the first conveying device and places the stacked empty pallets on the first conveying mechanism 171 of the first conveying device. The first conveying mechanism 171 of the first conveying device transports the stacked empty pallets to the return-to-warehouse transfer station 137. The stacker crane 134 transports the empty pallets from the return-to-warehouse transfer station 137 to the warehouse 13. Specifically, the WCS system is used to schedule the first conveying mechanism 171 of the first conveying device to transport empty pallets to the empty pallet stacking machine 21 for stacking. After stacking, an inbound task is generated. The WMS system is used to allocate storage locations for the empty pallets. The WCS is used to schedule the first conveying mechanism 171 of the first conveying device and the stacker crane 134 to transport the empty pallets back to the warehouse. It is understandable that the empty pallets returned by the first conveyor mechanism 171 and the second conveyor mechanism 173 can be stacked by the empty pallet stacking machine 21.

[0043] In this embodiment, the intelligent manufacturing and logistics system also includes a size detection device 23 mounted on the first conveying mechanism 171 of the first conveying device. The size detection device 23 is used to detect whether the size of the pallet containing the material to be returned to the warehouse meets the requirements. When the size of the pallet containing the material to be returned to the warehouse meets the requirements, the first conveying mechanism 171 of the first conveying device transports the material to the return receiving station 137, and the stacker crane 134 transports it back to the warehouse. When taking materials from the pallet, other materials left on the pallet may be encountered, or other materials may be stacked, resulting in the pallet being too wide or too high, making it impossible to place it in the storage location in the warehouse 13. Therefore, it is necessary to check whether the pallet containing the material meets the size requirements before the material is returned to the warehouse. If it does not meet the requirements, manual or other equipment is needed to arrange the material on the pallet until the size requirements are met before it can be returned to the warehouse. The WMS system is used to generate a tail material storage task when the material transported to the production line area 15 by the first conveyor is picked up and tail material is generated. The task is then transmitted to the LCS system and then to the WCS system. The WCS system is used to schedule the first conveyor to transport the tail material to the size detection device 23. After the size detection is qualified, the tail material is transported by the first conveyor to the return storage docking station 137 and the stacker crane 134 is scheduled to transport the tail material to the return storage location assigned by the WMS system.

[0044] In this embodiment, the control module determines whether to begin assembling product A or product B based on the order in which the equipment body, detected by the checkpoint detection device, arrives at the first station OP02. The total production time for both product A and product B is matched with the main assembly time from the first station OP02 to the second station OP11. Specifically, when the checkpoint detection device detects that the equipment body requiring product A has arrived at the first station OP02, assembly of product A begins; when the checkpoint detection device detects that the equipment body requiring product B has arrived at the first station OP02, assembly of product B begins.

[0045] In this embodiment, a first storage area 27 and a second storage area 28 can be set on both sides of the area formed by the warehouse 13, the production line area 15, and the first conveying device. Both the first storage area 27 and the second storage area 28 are located on one side of the assembly main line 11. The first storage area 27 and the second storage area 28 can be used to store parts that are directly assembled on the assembly main line.

[0046] The following is a brief description of the production process of product A.

[0047] When the inspection device detects that the main body of the equipment requiring product A has arrived at the first workstation OP02, it triggers a material requirement for product A. This requirement is then transmitted from the MES system to the LES system to generate a delivery request. The LES system packages the materials according to their part number, sequence, and batch size, and then sends the outbound request to the WMS system to generate an outbound task. The WMS system sends the outbound task to the WCS system via the LCS system. The WCS system dispatches the stacker crane 134 to transfer the outbound pallet from the storage location to the outbound receiving station 136, and dispatches the first conveyor mechanism 171 of the first conveyor device to transport the pallet containing the material to the first loading area 151. The loading robot 153 grabs the material from the pallet in the first loading area 151, automatically deducts the quantity of material on the pallet, and feeds back the corresponding deduction information to the WCS system, LCS system, WMS system, and CCS system. When the material on a pallet is not completely removed, the WMS system generates a residual material warehousing task and sends it to the WCS system via the LCS system. The WCS system dispatches the first conveyor mechanism 171 of the first conveyor device to transport the residual material to the size detection device 23. Once the size meets the requirements, the residual material continues to be input to the return warehouse transfer station 137 via the first conveyor mechanism 171. The WCS system dispatches the stacker crane 134 to transport the residual material to the return warehouse location assigned by the WMS system. When the material on a pallet is completely removed, the WCS system dispatches the first conveyor mechanism 171 to transport the empty pallet to the empty pallet stacking machine 21 for stacking. When a predetermined number of pallets are stacked into a pallet stack, a warehousing task is generated. The WCS system dispatches the first conveyor mechanism 171 to transport the pallet stack to the return warehouse transfer station 137 and dispatches the stacker crane 134 to transport the pallet stack to the storage location assigned by the WMS. Production lines 1 and 2 in production line area 15 produce product A (for example, the production cycle can be 120 minutes). After production, product A is transported to the second station OP11 by the second conveyor 19. At the second station OP11, product A is assembled into the main body of the equipment, and the work report for product A is completed in the MES system.

[0048] The following is a brief description of the production process of product B.

[0049] When the inspection device detects that the main body of the equipment to be assembled for product B has arrived at the first workstation OP02, it triggers a material requirement for product B. The material requirement is then transmitted from the MES system to the LES system to generate a delivery request. After the LES system packages the materials according to their part number, sequence, and batch size, it sends the outbound request to the WMS system to generate an outbound task. The WMS system sends the outbound task to the WCS system through the LCS system. The WCS system dispatches the stacker crane 134 to transfer the outbound pallet from the storage location to the outbound transfer station 136, and dispatches the first conveyor mechanism 171 of the first conveyor device to transport the pallet containing the material to the outbound elevator 175. During the process of the WCS system dispatching the stacker crane 134 and the first conveyor mechanism 171 to transport the pallet to the outbound elevator 175, the LCS system simultaneously makes a pre-call for the AGV through the RCS system, so that the AGV trolley 1733 waits at the outbound elevator 175. The RCS system dispatches the AGV trolley 1733 to transport the pallet to the second loading area 153. At this time, the material can be removed from the pallet, the quantity of material on the pallet is deducted, and the corresponding deduction information is fed back to the WCS system, LCS system, WMS system, and CCS system. When the material on the pallet is not completely removed, the WMS system generates a tail material warehousing task and sends it to the RCS system through the LCS system. The RCS system dispatches the AGV trolley 1733 to transport the tail material to the return hoist 176. The WCS system dispatches the first conveying mechanism 171 of the first conveying device to transport the tail material to the size detection device 23. Once the size meets the requirements, the tail material is continued to be input to the return docking station 137 through the first conveying mechanism 171. The WCS system dispatches the stacker crane 134 to move the tail material to the return storage location assigned by the WMS system. When the material on the pallet is depleted, the RCS system dispatches AGV 1733 to transport the empty pallet to the return hoist 176. The WCS system dispatches the first conveyor 171 to transport the empty pallet to the empty pallet stacker 21 for stacking. When a predetermined number of pallets are stacked, an inbound task is generated. The WCS system dispatches the first conveyor 171 to transport the pallet stack to the return transfer station 137 and dispatches the stacker crane 134 to move the pallet stack to the storage location assigned by the WMS. Production line 3 in production line area 15 produces product B (e.g., the production cycle can be 120 minutes). The completed product B is transported by the second conveyor 19 to the second workstation OP11. At the second workstation OP11, product B is assembled onto the main body of the equipment, and the work report for product B is completed in the MES system.

[0050] In the production process of products A and B, in one embodiment, the time from the generation of demand at the first station OP02 to the material being released from the warehouse is 5 minutes. The production cycle of a single product A or product B is 120 minutes. The second conveying device 19 takes 20 minutes to convey product A or product B. The safety time is designed to be no less than 30 minutes. The material requisition lead time of the entire product A or product B (i.e., the total production time of product A or product B) is 175 minutes (5+120+20+30). The assembly time of the first station OP02 is 180 minutes. The material requisition lead time is less than the assembly time of the first station OP02. Therefore, it is reasonable to locate the material requisition point of product A or product B at the first station OP02. The intermediate work-in-process inventory is minimized, which meets the lean requirements.

[0051] In this embodiment of the intelligent manufacturing and logistics system, in addition to efficient production scheduling to adapt to the production rhythm of the main assembly line, it is also compatible with the needs of both fast and slow production lines, and supports both conveyor lines and AGVs for intelligent logistics replenishment. This results in a lower overall system cost and greater flexibility. The system integrates MES, LES, WMS, LCS, WCS, and RCS systems to fully schedule and connect automated equipment such as automated warehouses and AGVs. It can meet the automated and flexible scheduling of logistics of different specifications. It eliminates the need for forklifts, achieves unmanned operation, and boasts high production line efficiency and a high degree of automation. Pallets and materials can be tagged with QR codes to ensure smooth and transparent information flow.
