Description

Technical Field

[0001] This invention belongs to the field of pipe production lines, and more specifically, relates to an intelligent production line and method for underfloor heating pipes. Background Technology

[0002] In the field of underfloor heating pipe production, semi-automated production mode has long dominated, but its drawbacks are becoming increasingly prominent, seriously restricting the industry's efficient, stable and sustainable development.

[0003] The excessive reliance on manual labor in the production process has become the primary bottleneck for efficiency improvement. From pipe winding to counting and packaging, every step requires manual input, which is not only slow but also susceptible to subjective factors such as worker fatigue and differences in skill level, resulting in an unstable production rhythm and making it difficult to meet the demands of a large-scale, fast-paced market.

[0004] Secondly, product quality stability is significantly affected by fluctuations in human operation. Human operation is easily affected by human factors, such as worker skill level and operating habits, leading to inconsistent product quality.

[0005] Secondly, the high and rising proportion of labor costs places a heavy burden on enterprises. The continuous increase in labor costs, coupled with the numerous manual operation steps and large human resource inputs, directly increases labor cost expenditures. Furthermore, the low efficiency of manual operations and the extended production cycle indirectly drive up production costs. Summary of the Invention

[0006] In view of the above-mentioned defects or improvement needs of the existing technology, the present invention provides an intelligent production line and production method for underfloor heating pipes, which adopts fully automated production and has high production efficiency.

A pallet-type continuous lift is used to receive pallets carrying semi-finished products on a first conveyor line and drive the pallets up or down to transport them to a second conveyor line. The pallet-type continuous lift has a power roller for receiving and transporting the pallets, and the power roller is driven to rotate by a power mechanism. An online weighing device is installed at the gap of the second conveyor line, and has a third conveyor line and a weighing device, used to weigh the semi-finished products while conveying them.

[0009] Preferably, it also includes a thickness measuring device set between the water cooling device and the traction device, used to measure whether the wall thickness of the floor heating pipe coming out of the water cooling device is qualified. If the wall thickness measurement is unqualified, the semi-finished product made of the floor heating pipe with unqualified wall thickness on the placement table is directly transferred to the unqualified product conveyor line. If the wall thickness measurement is qualified, the first truss robot picks up the semi-finished product on the placement table and puts the semi-finished product onto the empty tray on the first conveyor line.

[0010] Preferably, the packaging line includes a fourth conveyor line, an automatic carton opener, a vertical wrapping machine, a material handling robot, a fifth conveyor line, an automatic carton sealer, and a stacking robot, and: The fourth conveyor line is used to convey the semi-finished products thrown by the second gantry robot. The automatic carton opener is used to open folded cartons and place them onto the fifth conveyor line; The material handling robot is used to transfer the semi-finished products on the fourth conveyor line to the vertical winding machine, and to transfer the semi-finished products wrapped with protective film on the vertical winding machine to the open carton on the fifth conveyor line. The automatic carton sealing machine is used to seal open cartons conveyed on the fifth conveyor line; The coding robot is used to transfer sealed cardboard boxes to the qualified product storage area for storage.

[0011] Preferably, the packaging line includes a fourth conveyor line, an automatic case opener, a horizontal wrapping machine, a fifth conveyor line, an automatic case sealer, and a stacking robot, and: The fourth conveyor line is used to convey the semi-finished products thrown by the second gantry robot. The automatic carton opener is used to open folded cartons and place them onto the fifth conveyor line; The fourth conveyor line has a notch, and the horizontal winding machine is installed at the notch. The horizontal winding machine is used to wrap a protective film on the semi-finished product and then convey the semi-finished product with the protective film to the fourth conveyor line. The automatic carton sealing machine is used to seal open cartons conveyed on the fifth conveyor line; The coding robot is used to transfer sealed cardboard boxes to the qualified product storage area for storage.

[0012] Preferably, it also includes a labeling machine for affixing labels to sealed cartons conveyed on the fifth conveyor line.

[0013] Preferably, both the first truss manipulator and the second truss manipulator include a frame, a dual-axis moving platform, and an internal support clamp. The dual-axis moving platform is mounted on the frame, and the internal support clamp is mounted on the dual-axis moving platform for driving the internal support clamp to move up and down and horizontally along a first direction. A portion of the first conveyor line passes through the frame, and this portion of the first conveyor line passing through the frame extends along a second direction, which is perpendicular to the first direction. The internal support clamp has openable and closable grippers for fixing and releasing semi-finished products.

[0014] Preferably, it also includes an empty pallet return conveyor line; The second conveyor line has a slant wheel sorter, and the empty pallet return conveyor line connects the first conveyor line and the slant wheel sorter to allow empty pallets on the second conveyor line, whose semi-finished products have been taken away by the second gantry robot, to return to the first conveyor line.

[0015] Preferably, each pallet is equipped with an electronic tag, and the first and second conveyor lines are respectively equipped with multiple barcode readers to bind the electronic tag information of the pallet to the semi-finished products received on the pallet, so as to facilitate information traceability of the semi-finished products on the pallet and to transport qualified and unqualified semi-finished products to different locations.

[0016] Preferably, an extruder, a water cooling device, two traction devices, and two pipe winding machines together form a semi-finished product production line. One of the extruders in the semi-finished product production line is used to extrude two floor heating pipes, and each floor heating pipe passes through a water cooling device, a traction device, and a pipe winding machine. There are multiple semi-finished product production lines; Both the first truss manipulator and the second truss manipulator have multiple internal support clamps.

[0017] According to another aspect of the present invention, a method for producing intelligent production lines for underfloor heating pipes is also provided, comprising the following steps: 1) The extruder extrudes the underfloor heating pipes, which are then cooled and shaped by a water-cooling device before being pulled by a traction machine; 2) The traction machine pulls the floor heating pipe into the pipe winding machine. After the floor heating pipe is wound a set number of times in the pipe winding machine, the cutting tool of the pipe winding machine automatically cuts the floor heating pipe. After the pipe winding machine binds the cable ties to the semi-finished product to form a semi-finished product, the loading and unloading robot picks up the semi-finished product on the pipe winding machine and places it on the placement table. 3) The first truss robot picks up the semi-finished product on the placement table and puts the semi-finished product onto an empty pallet on the first conveyor line. The reader reads the electronic tag information on the pallet and binds it to the semi-finished product. The pallet and the semi-finished product on the pallet together form a semi-finished product assembly. 4) The first conveyor line transports the semi-finished components to the pallet-type continuous elevator, which then transfers the semi-finished components to the second conveyor line; 5) The second conveyor line transports the semi-finished components to the online weighing device at the gap of the second conveyor line for weighing, and then the online weighing device continues to transport the weighed semi-finished components to the second conveyor line. 6) For semi-finished components that have passed the weighing test, the second gantry robot will transfer the semi-finished components on the second conveyor line to the packaging line for packaging, and the controller will unbind the semi-finished products from the pallets. For semi-finished components that fail to meet the weight requirements, the second gantry robot transfers the semi-finished components on the second conveyor line to the non-conforming product conveyor line, and the controller unbinds the semi-finished product from the pallet.

[0018] In summary, compared with the prior art, the above-described technical solutions conceived by this invention can achieve the following beneficial effects: 1) This invention discloses an intelligent production line for underfloor heating pipes, encompassing automated operations at each stage, from extruding the pipes using an extruder, through cooling by a water-cooling device, traction by a traction device, winding, cutting, and binding by a pipe winding machine to form semi-finished products, to loading and unloading robots, a first gantry robot, a pallet-type continuous lift, an online weighing device, and a second gantry robot. This achieves full automation of the underfloor heating pipe production process, minimizing human intervention and ensuring high efficiency and continuous operation. Compared to traditional production methods, this significantly improves production efficiency and reduces problems such as unstable production rhythm and slow speed caused by manual operation, thus meeting the demands of large-scale, fast-paced markets.

[0019] 2) The present invention discloses an intelligent production line for underfloor heating pipes, in which a first conveyor line, a tray-type continuous lift, and a second conveyor line work together to ensure accurate transport of semi-finished products between processes. An online weighing device can detect the weight of the semi-finished products in real time. A second gantry robot transfers qualified products to the packaging line based on the weighing results, while unqualified products are sent to the unqualified product conveyor line. This achieves precise material sorting, ensuring a smooth and efficient production process and avoiding errors and delays that may occur due to manual sorting.

[0020] 3) The intelligent production line for underfloor heating pipes of this invention uses an online weighing device to weigh and detect semi-finished products, further ensuring product quality consistency. Only semi-finished products that meet the weight standard can enter the packaging stage; unqualified products are promptly rejected, ensuring high product quality.

[0021] 4) The intelligent production line for underfloor heating pipes of the present invention has significant beneficial effects in improving production efficiency, enhancing product quality, reducing production costs, optimizing production management, and ensuring production safety.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Reference Figures 1-9 A smart production line for underfloor heating pipes, comprising: Extruder 1 is used to extrude floor heating pipe 100; the extruded floor heating pipe 100 is made of plastic and can be subsequently wound into a ring shape.

[0026] Water cooling device 2 is used to cool the floor heating pipe 100 extruded by extruder 1; water cooling device 2 can be a water cooling tank or a spray device.

[0027] The traction device 4 is used to pull the water-cooled floor heating pipe 100. The traction device 4 includes an active belt drive mechanism and a driven belt drive mechanism. The active belt drive mechanism and the driven belt drive mechanism clamp the floor heating pipe 100. The active belt drive mechanism drives the floor heating pipe 100 to move and drives the driven belt drive mechanism to rotate.

[0028] The pipe winding machine 5 is used to wind the underfloor heating pipe 100 pulled by the traction device 4 a set number of turns, cut it, and tie the wound underfloor heating pipe 100 with cable ties to form a semi-finished product 101. The present invention can install an encoder on the pulley of the driving belt drive mechanism or the driven belt drive mechanism of the traction device 4 to obtain the number of turns of the underfloor heating pipe 100 by detecting the number of rotations of the pulley. Alternatively, an encoder can be installed on the winding tool of the pipe winding machine 5 for winding the underfloor heating pipe 100 to obtain the number of turns of the underfloor heating pipe 100. The pipe winding machine 5 adopts an existing winding machine for winding plastic pipes. The winding machine has a guiding mechanism, winding tool, cutting tool and other structures. The guiding mechanism is used to guide the underfloor heating pipe 100. The winding tool is used to wind the underfloor heating pipe 100 from the traction device 4 into a ring-shaped semi-finished product 101 with a set number of turns on the winding tool. The cutting tool is used to cut the underfloor heating pipe 100 after it has been wound a set number of turns.

[0029] A loading / unloading robot is used to pick up the semi-finished product 101 from the pipe winding machine 5 and place it on the placement table 14. After the underfloor heating pipe 100 is wound and tied on the winding tool of the pipe winding machine 5, the discharge tool on the pipe winding machine 5 can spring up the semi-finished product 101, thereby loosening the winding tool from the semi-finished product 101. The loading / unloading robot removes the annular semi-finished product 101 from the winding tool of the pipe winding machine 5 and places it on the placement table 14. Many existing pipe winding machines 5 are equipped with loading / unloading robots to automatically remove the semi-finished product 101 from the winding tool.

[0030] The first conveyor line 6 is used to convey the pallet 102. The first conveyor line 6 first conveys the empty pallet 102.

[0031] The first gantry robot 7 is used to pick up the semi-finished product 101 on the placement platform 14 and put the semi-finished product 101 onto the empty pallet 102 on the first conveyor line 6 so that the pallet 102 can carry the semi-finished product 101. After the pallet 102 carries the semi-finished product 101, the first conveyor line 6 conveys the pallet 102 carrying the semi-finished product 101.

[0032] A pallet-type continuous lift 8 is used to receive a pallet 102 carrying a semi-finished product 101 on a first conveyor line 6 and drive the pallet 102 to rise or fall and then transport it to a second conveyor line 15. The pallet-type continuous lift 8 has a power roller for receiving and transporting the pallet 102, and the power roller is driven to rotate by a power mechanism. Therefore, the power roller of the pallet-type continuous lift 8 can dock with the first conveyor line 6 (or the second conveyor line 15) after rising (or falling), thereby realizing the transfer of the pallet 102 from the first conveyor line 6 to the second conveyor line 15. If there are multiple pallet-type continuous lifts 8, and each pallet-type continuous lift 8 is connected to a branch conveyor of the first conveyor line 6, then the second conveyor line 15 can also be equipped with multiple branch conveyor lines. An inclined wheel sorting machine can be installed between the branch conveyor lines of the second conveyor line 15 and the main conveyor line of the second conveyor line 15 to transfer the pallet 102 from the branch conveyor lines of the second conveyor line 15 to the main conveyor line of the second conveyor line 15.

[0033] An online weighing device 9, located at the gap in the second conveyor line 15, comprises a third conveyor line and a weighing device, used to weigh the semi-finished product 101 while it is being conveyed. For example, the online weighing device 9 can obtain the weight of the semi-finished product 101 through an electronic belt scale, which is a device that can continuously and dynamically weigh materials without interrupting the movement of the conveyor belt.

[0034] The second gantry robot 10 is used to pick up semi-finished products 101 conveyed from the third conveyor line to the second conveyor line 15, and to put the qualified semi-finished products 101 onto the packaging line 11, and to put the unqualified semi-finished products 101 onto the unqualified product conveyor line 12. Multiple second gantry robots 10 can be arranged on the production line.

[0035] Packaging line 11 is used to package the qualified semi-finished products 101.

[0036] Furthermore, it also includes a thickness measuring device 3 set between the water cooling device 2 and the traction device 4, used to measure whether the wall thickness of the floor heating pipe 100 coming out of the water cooling device 2 is qualified. If the wall thickness measurement is unqualified, the semi-finished product 101, which is made of the floor heating pipe 100 with unqualified wall thickness, is directly transferred to the unqualified product conveyor line 12 on the placement platform 14. If the wall thickness measurement is qualified, the first truss robot 7 picks up the semi-finished product 101 on the placement platform 14 and puts the semi-finished product 101 onto the empty tray 102 on the first conveyor line 6.

[0037] The introduction of thickness measuring device 3 enables precise detection of the wall thickness of the underfloor heating pipe 100. Only semi-finished products 101 with qualified wall thickness can continue to flow on the production line, eliminating product quality problems caused by unqualified wall thickness. This ensures that every semi-finished product 101 entering subsequent processes meets quality standards, greatly improving the overall quality stability of the product. In the traditional production mode, underfloor heating pipes 100 with unqualified wall thickness may be discovered and rejected in multiple subsequent processes. This not only wastes a lot of manpower, material resources, and time, but also seriously affects the continuity of the production process. However, the thickness measuring device 3 of this invention can quickly and accurately screen out unqualified products at the key node after the underfloor heating pipe 100 is water-cooled and before traction, and directly transfer them to the unqualified product conveyor line 12. This avoids the ineffective flow of unqualified products in subsequent processes, making the production process smoother and more efficient, effectively shortening the production cycle, and improving production efficiency.

[0038] Thickness measuring device 3 works in conjunction with other automated equipment on the production line to achieve full-process monitoring of the production. By monitoring and recording wall thickness data in real time, abnormalities in the production process can be detected promptly, the source of the problem can be quickly located, and corresponding solutions can be implemented, effectively preventing the mass production of defective products. The application of thickness measuring device 3 is a significant manifestation of the intelligent upgrade of the underfloor heating pipe 100 production line. Together with extruder 1, water cooling device 2, traction device 4, and other equipment, it constitutes a highly automated and intelligent production system. This intelligent production mode not only improves production efficiency and product quality but also reduces reliance on manual operation, minimizes the impact of human factors on the production process, and makes production more stable and reliable.

[0039] Furthermore, the packaging line 11 includes a fourth conveyor line 111, an automatic carton opener 112, a vertical wrapping machine, a material handling robot, a fifth conveyor line 114, an automatic carton sealer 115, and a stacking robot 117, and: The fourth conveyor line 111 is used to convey the semi-finished product 101 delivered by the second gantry robot 10.

[0040] The automatic carton opener 112 is used to open folded cartons and place them onto the fifth conveyor line 114.

[0041] The material handling robot is used to transfer the semi-finished product 101 on the fourth conveyor line 111 to the vertical winding machine, and to transfer the semi-finished product 101 wrapped with protective film on the vertical winding machine to the open carton on the fifth conveyor line 114.

[0042] The automatic carton sealing machine 115 is used to seal open cartons conveyed on the fifth conveyor line 114.

[0043] The coding robot 117 is used to transfer sealed cardboard boxes to the qualified product storage area for storage.

[0044] From a packaging efficiency perspective, packaging line 11 achieves full automation of the packaging process. In traditional packaging processes, manual packing, wrapping protective film, sealing, labeling, and handling are not only time-consuming but also prone to efficiency fluctuations due to human factors. The carton opener of this invention can accurately complete the opening action in a short time and place the carton precisely on the conveyor line, saving significant time for subsequent processes. The vertical wrapping machine wraps the protective film evenly at a stable speed, avoiding the waste of film and insecure wrapping that can occur with manual wrapping. The addition of a robotic arm further enables efficient transfer of semi-finished products 101 from the vertical wrapping machine to the carton, and combined with the rapid sealing action of the automatic carton sealer 115, the entire packaging process is compact and efficient.

[0045] In terms of packaging quality, the high-precision operation of automated equipment ensures the consistency and stability of packaging. For example, the automatic carton opener 112 avoids the problem of carton deformation caused by uneven force during manual opening, ensuring the integrity and appearance quality of the carton. The uniform winding technology of the vertical wrapping machine provides all-round, no-dead-angle protection for the semi-finished product 101 of the underfloor heating pipe 100, effectively preventing damage to the product during handling and storage. The automatic carton sealing machine 115 ensures that the sealing tape is applied flat and firmly through a standardized sealing process, eliminating the risk of product scattering due to improper sealing. The labeling machine 116 affixes standardized labels to the products with precise positioning and clear printing results, which not only improves product traceability but also enhances the product's visual recognizability. The palletizing robot neatly stacks the packaged products according to a preset program, facilitating subsequent transportation and warehousing management and reducing product damage caused by unstable stacking. Overall, this packaging line 11 greatly improves packaging quality and reduces the product loss rate caused by packaging problems.

[0046] Furthermore, the packaging line 11 includes a fourth conveyor line 111, an automatic carton opener 112, a horizontal wrapping machine 113, a fifth conveyor line 114, an automatic carton sealer 115, and a bartering robot 117.

[0047] The fourth conveyor line 111 is used to convey the semi-finished product 101 delivered by the second gantry robot 10.

[0048] The automatic carton opener 112 is used to open folded cartons and place them onto the fifth conveyor line 114.

[0049] The fourth conveyor line 111 has a notch, and the horizontal winding machine 113 is installed at the notch. The horizontal winding machine 113 is used to wrap a protective film on the semi-finished product 101 and then convey the semi-finished product 101 wrapped with the protective film to the fourth conveyor line 111.

[0050] The automatic carton sealing machine 115 is used to seal open cartons conveyed on the fifth conveyor line 114.

[0051] The coding robot 117 is used to transfer sealed cardboard boxes to the qualified product storage area for storage.

[0052] Compared to the vertical wrapping machine used in packaging line 11, the horizontal wrapping machine 113 is seamlessly connected to the fourth conveyor line 111. The semi-finished product 101 can be directly wrapped on the conveyor line without additional transfer, realizing a continuous and efficient packaging process. The horizontal wrapping machine 113 wraps the protective film evenly in the horizontal direction, adhering more tightly to the product surface, effectively preventing the packaging film from loosening and falling off during transportation, and reducing the risk of product damage. Fourth, it enhances the degree of automation, reduces manual intervention, lowers labor costs, and reduces errors and risks caused by manual operation.

[0053] The intelligent packaging line 11 of this invention further improves the packaging quality and efficiency of products. The coordinated operation of equipment such as automatic case opener 112, material handling robot, vertical (horizontal) wrapping machine, automatic case sealer 115, labeling machine 116, and bartering robot 117 realizes a fully automated process from semi-finished product 101 to finished product packaging. This not only improves the speed and quality of packaging, but also effectively prevents product damage during the packaging process and improves the product's integrity rate during transportation and storage.

[0054] The first to fifth conveyor lines 6 and 114 mentioned above can be conventional plate chain conveyors or belt conveyors.

[0055] Furthermore, it also includes a labeling machine 116 for affixing labels to sealed cartons conveyed on the fifth conveyor line 114. The automated operation of the labeling machine 116 significantly improves the efficiency of the packaging process, reduces errors and costs that may result from manual labeling, and accelerates the overall operating speed of the packaging line 11. The precise operation of the labeling machine 116 ensures the accuracy and consistency of label information, avoiding logistics and sales problems caused by incorrect or unclear labels, and optimizing supply chain management.

[0056] Furthermore, both the first truss manipulator 7 and the second truss manipulator 10 include a frame 701, a dual-axis moving platform 702, and an inner support clamp 703. The dual-axis moving platform 702 is mounted on the frame 701, and the inner support clamp 703 is mounted on the dual-axis moving platform 702 for driving the inner support clamp 703 to move up and down and horizontally along a first direction. A portion of the first conveyor line 6 passes through the frame 701, and this portion of the first conveyor line 6 extends along a second direction perpendicular to the first direction. The inner support clamp 703 has openable and closable grippers for fixing and releasing the semi-finished product 101.

[0057] The gantry robot's dual-axis moving platform 702 endows the robot with extremely high flexibility and operating range, enabling it to quickly and accurately adapt to the position of the semi-finished product 101 on the pallet 102, greatly improving production efficiency. The ingenious design of the internal support clamp 703 not only ensures the stability of the semi-finished product 101 during movement but is also particularly suitable for semi-finished products 101 coiled into a ring shape. Furthermore, the gantry robot's automated adaptability makes it an indispensable part of the production line, ensuring the continuity and stability of the entire production process, reducing manual intervention, lowering labor intensity, and further optimizing production costs.

[0058] Furthermore, it also includes an empty pallet return conveyor line 13.

[0059] The second conveyor line 15 includes a slanted wheel sorter. The empty pallet return conveyor line 13 connects the first conveyor line 6 and the slanted wheel sorter, allowing empty pallets 102 on the second conveyor line 15, whose semi-finished products 101 have been removed by the second gantry robot 10, to return to the first conveyor line 6. The empty pallet return conveyor line 13, in conjunction with the slanted wheel sorter, achieves efficient return and reuse of empty pallets 102, avoiding idle waste of pallet 102 resources, increasing pallet 102 turnover rate, and reducing production costs.

[0060] Furthermore, each of the pallets 102 is equipped with an electronic tag, and the first conveyor line 6 and the second conveyor line 15 are respectively equipped with multiple code readers to bind the electronic tag information of the pallet 102 with the semi-finished products 101 on the pallet 102, so as to facilitate information traceability of the semi-finished products 101 on the pallet 102 and to transport qualified and unqualified semi-finished products 101 to different locations respectively.

[0061] The use of electronic tags on pallet 102 greatly enhances the traceability of the production process. By binding the electronic tag information on pallet 102 to semi-finished product 101, enterprises can quickly and accurately track the production details of each batch of products, such as production time, equipment parameters, and quality inspection results. This allows for rapid identification of the source of problems and effective corrective measures to reduce losses when product quality issues arise. On the production line, qualified and unqualified semi-finished products 101 need to be accurately sorted. Electronic tag binding automates this process; the barcode reader can quickly read the information on pallet 102 and automatically sort according to preset rules without manual intervention, greatly reducing sorting time, lowering the probability of errors, making the production line more efficient and smooth, and improving overall production efficiency. Electronic tag binding also facilitates resource recycling. In the production line, empty pallets 102 need to be returned to the first conveyor line 6 for reuse. Electronic tags can accurately track the usage status of pallet 102, ensuring accurate matching of information between pallet 102 and semi-finished product 101, avoiding material waste caused by information confusion, realizing efficient recycling of pallet 102, reducing the procurement cost of new pallet 102, and indirectly reducing production costs.

[0062] Furthermore, an extruder 1, a water-cooling device 2, two traction devices 4, and two pipe winding machines 5 together form a semi-finished product 101 production line. One of the extruders 1 in the semi-finished product 101 production line is used to extrude two underfloor heating pipes 100, and each underfloor heating pipe 100 passes through the water-cooling device 2, a traction device 4, and a pipe winding machine 5. Multiple semi-finished product 101 production lines are available, and both the first gantry robot 7 and the second gantry robot 10 have multiple internal support grippers 703. Compared to single-line production, the production capacity is multiplied, meeting the needs of large-scale orders and enhancing the company's market competitiveness. Multiple semi-finished product 101 production lines can operate simultaneously, achieving parallel operations and significantly shortening the production cycle. The multi-grip gantry robot can simultaneously grasp multiple semi-finished products 101, reducing the switching time between different tasks and improving handling efficiency.

[0063] Reference Figure 10 According to another aspect of the present invention, a method for producing intelligent production lines for underfloor heating pipes is also provided, comprising the following steps: 1) Extruder 1 extrudes floor heating pipe 100. After being cooled and shaped by water cooling device 2, floor heating pipe 100 is pulled by traction machine 4.

[0064] 2) The traction machine 4 pulls the floor heating pipe 100 into the pipe winding machine 5. After the floor heating pipe 100 is wound a set number of times in the pipe winding machine 5, the cutting tool of the pipe winding machine 5 automatically cuts the floor heating pipe 100. After the pipe winding machine 5 binds the semi-finished product 101 with cable ties to form the semi-finished product 101, the loading and unloading robot picks up the semi-finished product 101 on the pipe winding machine 5 and places it on the placement table 14.

[0065] 3) The first truss robot 7 picks up the semi-finished product 101 on the placement table 14 and puts the semi-finished product 101 onto the empty pallet 102 on the first conveyor line 6. The reader reads the electronic tag information on the pallet 102 and binds it to the semi-finished product 101. The pallet 102 and the semi-finished product 101 on the pallet 102 together form a semi-finished product assembly.

[0066] 4) The first conveyor line 6 conveys the semi-finished components to the pallet-type continuous elevator 8, and the pallet-type continuous elevator 8 then transfers the semi-finished components to the second conveyor line 15.

[0067] 5) The second conveyor line 15 conveys the semi-finished components to the online weighing device 9 at the gap of the second conveyor line 15 for weighing, and then the online weighing device 9 continues to convey the weighed semi-finished components to the second conveyor line 15.

[0068] 6) For the semi-finished components that have passed the weighing test, the second gantry robot 10 transfers the semi-finished components 101 on the second conveyor line 15 to the packaging line 11 for packaging, and the controller unbinds the semi-finished components 101 from the pallet 102.

[0069] For semi-finished components that fail to meet the weight requirements, the second gantry robot 10 transfers the semi-finished components from the second conveyor line 15 to the non-conforming product conveyor line 12, and the controller unbinds the information of the semi-finished product 101 from the pallet 102. The non-conforming product conveyor line 12 then transports the non-conforming products to the designated area.

[0070] The production method of this invention reduces manual intervention by automating the processes of extrusion, cooling, traction, winding, cutting, weighing, sorting and packaging, thereby achieving efficient and continuous operation of the production process, greatly shortening the production cycle and improving production efficiency.

[0071] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
