Description

Technical Field

[0001] The present invention relates to the technical field of elevator wall panel production, and in particular to a complete production line and a production method for elevator wall panels. Background Art

[0002] The elevator car is the box-shaped structure used to transport passengers and other loads. One of its core components is the wall panel. As a crucial plate-shaped member of the elevator car, the wall panel, along with the floor, roof, and doors, forms a closed space. The production of the wall panel falls under the category of sheet metal manufacturing, and the production process encompasses multiple steps, including shearing, punching, bending, gluing, welding, and packaging.

[0003] Because the wall panels of a car are usually made of a variety of different specifications, the widths of different wall panels in the same car may vary, and the heights of different cars vary greatly. Therefore, the production methods and models of wall panels are also diverse.

[0004] Currently, there are two main methods for producing siding panels. The first is traditional off-island production, where each process is independently completed by a single piece of equipment, with panels and production instructions manually transferred between processes. This production method is relatively inefficient and prone to quality issues such as surface scratches during product transfer.

[0005] The second approach is production on a production line, using small batches. However, this production method also has some significant drawbacks. First, existing elevator sheet metal production lines are mostly imported equipment, which is expensive and often lacks additional features such as automated sorting and optimized material utilization. Second, the production lines are not complete sets. After the wall panels complete the production process, they still require manual picking and packing according to the packing list. Furthermore, due to the lack of a buffer warehouse in the middle of the production line, material utilization is relatively low, and there is a lack of effective means to handle excess material.

[0006] To sum up, although production line-type small batch production has improved production efficiency to a certain extent, there are still some problems that need to be solved urgently. Summary of the Invention

[0075] A complete production line for elevator siding, which includes the following in order of production:

[0076] MES system 1, used to formulate production plans based on order requirements and issue production instructions to material management module 2, plate positioning and cutting module 3, plate buffer module 4, punching and bending module 5, quality inspection and gluing module, plate assembly and welding module 7, and finished product output and packaging module 8;

[0077] Material Management Module 2: used to store and manage the raw materials required for elevator siding production;

[0078] Plate positioning and cutting module 3: used to position the raw material plates according to production requirements and cut the positioned raw material plates to form usable plates;

[0079] Plate buffer module 4: equipped with a plate buffer library 41, which is provided with at least one replaceable buffer library layout scheme, including fan-shaped vertical storage, flat gantry storage and access, or side-standing storage; the plate buffer library 41 is used to temporarily store available plates;

[0080] Punching and bending module 5: Punching and bending the available sheet materials to form the preliminary shape of the elevator wall panels;

[0081] Quality inspection and gluing module: conduct quality inspection on the preliminary shape of the elevator wall panels and gluing the qualified elevator wall panels;

[0082] Panel assembly and welding module 7: assembles the cleaned and glued elevator wall panels and fixes them by welding to form a complete elevator wall panel;

[0083] Finished product output and packing module 8: output the complete elevator wall panels and pack them according to the packing requirements;

[0084] Also includes:

[0085] Multiple manipulators: used to connect respectively between the material management module 2, the plate positioning and cutting module 3, the plate buffer module 4, the punching and bending module 5, the quality inspection and gluing module, the plate assembly and welding module 7 and the finished product output and packing module 8;

[0086] The central control system is electrically connected to the MES system 1, the material management module 2, the plate positioning and cutting module 3, the plate buffer module 4, the punching and bending module 5, the quality inspection and gluing module, the plate assembly and welding module 7 and the finished product output and packing module 8, and is used for overall scheduling, monitoring of the production process, and adjusting the working parameters of each module according to production needs.

[0087] like Figure 1-3 As shown, the working principle of this complete production line for elevator siding panels is based on a highly automated and intelligent production process, as follows:

[0088] MES system 1 formulates a production plan: Based on the customer's order requirements, MES system 1 first formulates a detailed production plan, including the required raw material types, quantities, production sequence, etc., and issues these production instructions to the material processing module.

[0089] Raw material management: After receiving the production instructions, the material management module 2 prepares the corresponding raw material plates according to the plan and places them in an easily accessible location for use by subsequent modules.

[0090] Plate positioning and shearing: The plate positioning and shearing module 3 accurately positions the raw material plates according to production requirements, and uses shearing equipment to cut them into the required size to form usable plates.

[0091] Plate buffer: The cut usable plates are sent to the plate buffer module 4, which has a variety of replaceable buffer storage layout schemes, such as Figure 4-6 The shown fan-shaped vertical storage, flat gantry storage or side-standing storage can meet the needs of different production stages. The buffer warehouse temporarily stores these plates and facilitates subsequent processing in the punching and bending module 5 after a certain amount of storage is reached.

[0092] Punching and bending: In the punching and bending module 5, the available sheet material can be punched and bent to form the preliminary shape of the elevator wall panel.

[0093] Quality Inspection, Cleaning and Gluing: The pre-formed elevator siding enters the quality inspection and gluing module, where it undergoes quality inspection to ensure product compliance. Qualified elevator sidings are then cleaned and glued in preparation for subsequent assembly.

[0094] Panel assembly and welding: The elevator wall panels that have been cleaned and glued are assembled in the panel assembly and welding module 7 and fixed by welding to form a complete elevator wall panel.

[0095] Finished product output and packaging: Finally, the complete elevator wall panels are sent to the finished product output and packaging module 8, which performs packaging operations according to the packaging requirements and prepares for shipment.

[0096] Throughout the production process, multiple robotic arms connect various modules, automating material handling and processing operations. A central control system coordinates and monitors the overall production process, adjusting each module's operating parameters in real time based on production needs to ensure efficient and orderly production.

[0097] In summary, the beneficial effects of the present invention are as follows:

[0098] 1. Improve production efficiency: Through highly automated and intelligent production processes, production efficiency can be greatly improved and production cycle can be shortened.

[0099] 2. Improve product quality: The precise connection between modules and quality control measures ensure high product quality and reduce the defective product rate.

[0100] 3. Reduce labor costs: The introduction of multiple robots reduces manual operations, reduces labor costs, and improves production safety.

[0101] 4. Strong flexibility: The plate buffer module 4 is equipped with a variety of replaceable buffer storage layout schemes, which can flexibly adapt to the needs of different production stages and improve the flexibility and adaptability of the production line.

[0102] 5. Easy to monitor and manage: The introduction of the central control system makes the entire production process easy to monitor and manage, and can promptly detect and solve problems in production to ensure smooth production.

[0103] To further illustrate, the material management module 2 includes a stacker 21, a double-row multi-layer three-dimensional material warehouse 22, and a material outbound sheet separation platform 23;

[0104] The double-row multi-layer three-dimensional material warehouse 22 is used to store raw material plates;

[0105] The stacker 21 is used to extract the raw material plates required for the production of elevator wall panels in the production plan from the double-row multi-layer three-dimensional material warehouse 22;

[0106] The material outbound sheet separation platform 23 is used to separate the raw material sheets delivered by the stacker 21 into individual sheets.

[0107] Specifically, such as Figure 2-3 As shown, the stacker 21 extracts the required materials from the double-row, multi-layered storage 22 according to the material list and then transports them to the material outbound sheet sorting platform 23 for single-sheet retrieval. To save time, after completing one retrieval, the stacker 21 immediately moves to the next material specification location in the double-row, multi-layered storage 22 for the next retrieval.

[0108] To further illustrate, the plate positioning and shearing module 3 includes a material positioning platform 31, a shearing center 32, a first conveying line 33, a coding line 34 and a residual material processing line 35;

[0109] The plurality of manipulators include manipulator No. 100;

[0110] The No. 1 manipulator 100 is located between the material outbound and sheeting platform 23, the material positioning platform 31, and the shearing center 32. The No. 1 manipulator 100 is used to first grab the raw material sheet from the material outbound and sheeting platform 23 to the material positioning platform 31 for positioning, and then grab the positioned raw material sheet to the shearing center 32 for precise shearing;

[0111] The first conveying line 33 has two output ends, one of which is used to convey the usable plates after being cut by the shearing center 32 to the coding line 34, and the coding line 34 is used to code or laser code the usable plates after being cut by the shearing center 32; the other output end is used to recycle the unusable plates after being cut by the shearing center 32.

[0112] Specifically, such as Figure 2-3 As shown, after receiving the production instructions and material requirements, the shearing center 32 uses its internal software system to optimize material utilization and efficiency. The software can combine shearing tasks of the same material in multiple orders according to the order situation to improve the utilization rate of the plate.

[0113] For example, when producing 9 wall panels for order A, the same material tasks in order B can be inserted into the panels in order A to achieve efficient use of materials.

[0114] The shearing center 32 will also provide a list of required materials to the material management module 2 based on the calculation results for subsequent material management and tracking.

[0115] Therefore, through the above-mentioned combined shearing and optimized material utilization calculation, the waste of plates is reduced and the production cost is lowered.

[0116] To further illustrate, the sheet material buffer module 4 further includes a multi-layer sheet material taking and placing line 42, which is located between the coding line 34 and the punching and bending module 5, and is used to transport the usable sheets that have been coded or laser-printed;

[0117] The plurality of manipulators further includes a manipulator No. 200;

[0118] The robot No. 2 200 is located between the multi-layer plate picking and placing line 42 and the plate cache 41. The robot No. 2 200 is used to transfer the available plates transported by the multi-layer plate picking and placing line 42 to the plate cache 41 for temporary storage according to the production plan, or to take out the available plates stored in the plate cache 41 and put them back into the multi-layer plate picking and placing line 42 to be transported to the punching and bending module 5.

[0119] like Figure 2-3 As shown, when the multi-layer plate picking and placing line 42 detects that the plate is required for the current production of order A, it directly connects to the level where the second conveyor line 51 of the punching and bending module 5 is located for continuous conveying. When the multi-layer plate picking and placing line 42 detects that the plate is required for the next order B, the multi-layer plate picking and placing line 42 rises or descends to the level where the plate buffer 41 is located, and the No. 2 robot 200 grabs and transfers the plate to the plate buffer 41 for caching, thereby improving the flexibility of the production line.

[0120] To further illustrate, the punching and bending module 5 includes a second conveyor line body 51, a CNC turret punch press 52, a turning platform 53, a short side bender 54 and a bending center 55;

[0121] The plurality of manipulators further include a manipulator No. 300 and a manipulator No. 400;

[0122] The No. 3 manipulator 300 is located between the second conveyor line 51 and the CNC turret punch press 52. The No. 3 manipulator 300 is used to transfer the usable plates conveyed by the second conveyor line 51 to the CNC turret punch press 52 for punching.

[0123] The robot No. 4 400 is located between the CNC turret punch press 52, the flipping platform 53 and the short side bending machine 54. The robot No. 4 400 is used to transfer the plate punched by the CNC turret punch press 52 to the flipping platform 53 for flipping, and then transfer the flipped plate to the short side bending machine 54 and the bending center 55 for short side bending and multilateral bending respectively, to form the preliminary shape of the elevator wall panel.

[0124] Specifically, such as Figure 2-3 As shown, robot arm 300 grabs the usable plate from the second conveyor line 51 and places it on the CNC turret punch press 52. After the CNC turret punch press 52 clamps and positions it, it punches. After the punching is completed, robot arm 300 conveys the punched plate to the other end of the CNC turret punch press 52. Robot arm 400 then grabs the punched plate and places it on the flip platform 53 for flipping and repositioning. If the plate material is a cold plate, no flipping is required. Then robot arm 400 grabs the plate and places it on the bending machine for short-side bending. After the short-side bending is completed, robot arm 400 places the plate on the bending center 55. The bending center 55 repositions the plate and then bends the long side. After the long side bending is completed, the elevator wall panel with a preliminary shape is formed and then conveyed to the quality inspection and gluing module.

[0125] To further illustrate, the quality inspection and gluing module includes a detection line 61 and a cleaning and gluing line 62;

[0126] The detection line 61 is used to scan the code of the elevator wall panel in the preliminary shape to obtain information and then perform material detection and size detection. If the size detection result exceeds the specified range, an alarm will be issued to remind manual removal. If the size detection is within the specified range, it will be transported to the cleaning and gluing line 62 or the plate assembly and welding module 7 according to the material detection result. The cleaning and gluing line 62 is used to select whether to clean and gluing according to the material of the elevator wall panel.

[0127] Specifically, such as Figure 2-3As shown, the detection line 61 scans the code to obtain information of the preliminary shape of the elevator wall panel and then performs size detection. If the size detection result exceeds the specified range, an alarm will be issued to remind manual removal. If the size detection is in line with the specified range, further material detection will be performed. When the plate material is stainless steel or color-coated plate, it will be transported to the cleaning and gluing line 62, and the cleaning and gluing line 62 will clean and gluing the non-decorative surface on the back of the plate. After the gluing is completed, it will be transported to the plate assembly and welding module 7; when the plate material is cold plate, the cleaning and gluing line 62 will only transport the plate to the plate assembly and welding module 7.

[0128] To further illustrate, the plate assembly and welding module 7 includes a reinforcement assembly line 71, a reinforcement forming machine 72, a repositioning platform 73, a traction line 74, a glue pressing device 75 and a butt welding machine 76;

[0129] The plurality of manipulators further include manipulator No. 5 500 and manipulator No. 6 600;

[0130] The reinforcement assembly line 71 has two reinforcement input ends, one of which is connected to the detection line 61, and the other is connected to the cleaning and gluing line 62. The output end of the reinforcement assembly line 71 is connected to the reinforcement forming machine 72. The reinforcement assembly line 71 is used to transport the elevator wall panel to the reinforcement forming machine 72, and the reinforcement forming machine 72 is used to process and shape the reinforcement body to form a reinforcement body;

[0131] The No. 5 manipulator 500 is located between the reinforcement assembly line 71, the reinforcement forming machine 72 and the repositioning platform 73. The No. 5 manipulator 500 transfers the reinforcement formed by the reinforcement forming machine 72 to the repositioning platform 73 for positioning, and then transfers the positioned reinforcement to the reinforcement assembly line 71. The reinforcement assembly line 71 is used to assemble the reinforcement with the elevator wall panel to form an assembled elevator wall panel.

[0132] The input end of the traction line body 74 is connected to the reinforcement assembly line body 71, and the traction line body has two traction output ends, the other traction output end is connected to the No. 6 manipulator (600), and one of the traction output ends is connected to the butt welding machine (76). The traction line body (74) is used to transfer the assembled elevator wall panel to the No. 6 manipulator (600) or the butt welding machine (76) according to the material of the plate;

[0133] The No. 6 manipulator (600) is used to perform laser welding or rivetless riveting on the connection positions of the assembled elevator wall panels, and then transport them to the glue pressing device (75). The glue pressing device (75) is used to glue the welded elevator wall panels to form complete elevator wall panels;
