Description

Technical Field

[0001] This invention relates to a fully automated production line for aluminum sheet rolling. Background Technology

[0002] In the production process of aluminum blown plastic sheets, the production of blank sheets typically requires hot rolling two aluminum sheets together to form a composite sheet. Traditional aluminum sheet rolling methods have many problems, such as low production efficiency, large human error, and unstable product quality. With the development of industrial automation, the requirements for the automation level and quality control of aluminum sheet rolling production are becoming increasingly stringent. Therefore, there is an urgent practical need to develop a highly efficient and stable fully automated aluminum sheet rolling production line.

[0003] This process requires placing the pre-treated aluminum plates into a hot furnace heating system, where the system heats the plates to a suitable temperature. Once the aluminum plates reach the set temperature, a certain amount of pressure is applied to force the plates together tightly.

[0004] In traditional production models, processes such as heating and rolling aluminum sheets often require manual intervention. This manual intervention in each step increases labor costs and makes the process susceptible to human error. Differences in worker skills and experience lead to low production efficiency and inconsistent product quality—a common phenomenon in many industrial production scenarios.

[0005] When transporting heated aluminum sheets to the rolling mill, they need to be placed accurately within the mill's working area. In actual production, manual operation is susceptible to various factors, such as stress and fatigue. When workers need to accurately place the heated aluminum sheets within the rolling mill's working area, the high temperature and weight of the sheets make the operation difficult, and the possibility of operational errors is reasonable. For example, the aluminum sheet may not be correctly aligned with the rolling mill inlet, causing jamming or tilting, which is easily possible under manual operation.

[0006] Heated aluminum plates reach extremely high temperatures, posing a real risk of burns to workers who accidentally come into contact with them during handling. The harmful effects of high-temperature objects on human skin are obvious, especially in industrial production environments where workers are prone to negligence, increasing the likelihood of burns. Summary of the Invention

[0007] To overcome the shortcomings of current aluminum plate rolling equipment that involves production hazards during manual operation, this invention provides a fully automated aluminum plate rolling production line.

[0008] The technical solution of the present invention to solve its technical problem is: a fully automatic aluminum plate rolling production line, which includes, from front to back, an electric furnace equipped with a feeding belt, a transport positioning machine, and a rolling mill, and a transfer robot is provided between the electric furnace and the transport positioning machine to transfer materials; Electric furnaces, rolling mills, and transfer robots are all models that are already available on the market, and will not be discussed in detail here.

[0009] The feeding belt includes a chain belt system that partially enters the heating chamber of the electric furnace. The chain belt system has sprockets at both ends to drive the chain belt to rotate. At least one of the sprockets has a sprocket motor on one side to drive its rotation. The chain belt system has plate partitions so that aluminum plates can be placed upright. The transport positioning machine includes a frame on which rollers are arranged, with a through gap between adjacent rollers. Each roller has a drive sprocket at its end, driven by a drive chain. An extension plate is located at the rear of the frame, with auxiliary support balls and several roller travel grooves on the extension plate. The frame also includes a centering device comprising a centering drive mechanism, a left centering edge, and a right centering edge. The centering drive mechanism drives the left and right centering edges to move closer together. The left and right centering sides are provided with several vertically arranged centering rollers. The rear centering rollers extend from the roller travel grooves, and the front centering rollers extend from the through gaps between adjacent rollers on the frame. The middle of the transport positioning machine is also provided with a front-to-back aluminum plate pusher. The aluminum plate pusher is equipped with a pusher lifting cylinder to drive the aluminum plate pusher to extend or retract. The aluminum plate pusher is driven by a pusher driving device, which is located in the middle of the frame and is not higher than the upper limit of the roller height. The rear end of the extension plate is mounted at the inlet of the rolling mill; The rolling mill has an upper roller and a lower roller. The aluminum sheet is brought into the space between the upper roller and the lower roller from the extension plate to complete the rolling process, and then exits from the front end of the rolling mill as a finished product.

[0010] To facilitate the layout of the aluminum plate pusher, the rollers are arranged in two rows, divided into a left roller group and a right roller group. The left roller group has a left sprocket at the left end of the rollers, and a left roller drive motor at the lower end of the left roller group. The left roller drive motor drives a left roller transmission chain to transmit power to the left sprocket, thereby rotating the left roller group. The right roller group has a right sprocket at the right end of the rollers, and similarly, the right roller group is driven to rotate by a right roller drive motor. With this design, the aluminum plate pusher is installed between the left and right roller groups, which can easily maintain the balance when pushing the aluminum plate.

[0011] In a preferred embodiment, the chain system has two conveyor chains, left and right, with the plate spacers installed on the conveyor chains. With this arrangement, the lower left end of the aluminum plate rests on the left conveyor chain, and the right end rests on the right conveyor chain, thus ensuring that the aluminum plate is firmly clamped both in the electric furnace and after it has been removed from the furnace.

[0012] To control the temperature, the heating chamber of the electric furnace is equipped with a liftable door at the end, which can be lowered to seal the electric furnace.

[0013] To ensure smooth sliding of the aluminum plate, a cover plate is provided above the auxiliary support ball, and the cover plate has a ball hole corresponding to the auxiliary support ball, so that the ball body of the auxiliary support ball protrudes upward from the ball hole.

[0014] A preferred layout of the extension plate includes a main plate strip and two rows of side plate strips located on both sides of the main plate strip, wherein the roller travel groove is disposed between adjacent side plate strips.

[0015] Furthermore, the aluminum plate pusher slides in a pusher stroke groove, which is located in the middle of the main strip of the extension plate.

[0016] A preferred embodiment of an assisted support ball includes a ball base and a rotatable ball body embedded in the ball base.

[0017] To facilitate gripping the aluminum plate, the gripper of the transfer robot uses a two-finger cylinder. An extension bar is connected to the finger of the two-finger cylinder, and friction blocks are provided on the opposite side of the end of the extension bar.

[0018] A preferred centering drive mechanism includes a front transverse guide rod and a rear transverse guide rod fixed to the frame. An electric actuator drive rail is provided between the front and rear transverse guide rods. The left and right centering sides are slidably mounted on the electric actuator drive rail and are installed on the front and rear transverse guide rods. The mechanism also includes two centering side drive motors that drive the left and right centering sides respectively. The left centering side is composed of a main part that is movable in the frame and an extension part that is movable in the extension plate. The main part and the extension part are screwed together to form the left centering side. Centering rollers on the extension part complete the centering of the aluminum plate on the extension plate. The right centering side is similarly configured.

[0019] In this invention, the pre-treated aluminum plate is placed upright between the plate dividers of the automated conveyor belt system. The conveyor belt system has two sets of conveyor chains, left and right. The plate dividers are installed on the conveyor chains, with the left end of the aluminum plate resting on the left conveyor chain and the right end resting on the right conveyor chain. This securely clamps the aluminum plate. The sprocket motor is turned on, driving the sprocket to rotate, which in turn drives the conveyor belt. The conveyor belt system partially enters the heating chamber of the electric furnace, and the aluminum plate enters the heating chamber with the conveyor belt for heating. After the aluminum plate is heated in the electric furnace, the transfer robot is activated. The gripper of the transfer robot uses a two-finger cylinder, with extension bars connected to the fingers of the two-finger cylinder. Friction blocks are provided on the opposite sides of the ends of the extension bars. The friction blocks are used to clamp the aluminum plate, transferring it from the outlet of the electric furnace to the transport positioning machine.

[0020] The transport positioning machine has rollers arranged on its frame. The left roller group has a left sprocket at the left end of each roller, which is driven by a left roller drive motor to rotate the left roller group. The right roller group has a right sprocket at the right end of each roller, which is also driven by a right roller drive motor. The aluminum plate is placed on the rollers and transported forward as the rollers rotate.

[0021] The centering drive mechanism is activated, which drives the left and right centering sides to move closer together. Several vertically positioned centering rollers are installed on the left and right centering sides. The rear centering rollers extend from the roller travel grooves on the extension plate, while the front centering rollers extend from the through-gap between adjacent rollers on the frame. These centering rollers center the aluminum plate during transport, ensuring it is in the correct position.

[0022] When the aluminum plate is transported to the middle of the transport positioning machine, the pusher drive device drives the aluminum plate pusher, which is installed between the left roller group and the right roller group, to push the aluminum plate to continue moving forward to the extension plate section, maintaining the balance of the aluminum plate during the pushing process.

[0023] The rear end of the extension plate of the transport positioning machine is mounted at the inlet of the rolling mill. Under the push of the aluminum plate pusher, the aluminum plate is carried from the extension plate into the space between the upper and lower rollers of the rolling mill. The upper and lower rollers apply pressure to the aluminum plate to complete the rolling process. The rolled product is then output from the front end of the rolling mill.

[0024] After the aluminum plate pusher completes one cycle, it is driven downward by the pusher lifting cylinder. The pusher drive device pushes it back to the front of the next aluminum plate on the frame, waiting to push the next aluminum plate into the rolling mill, thus realizing the continuous rolling operation of aluminum plates.

[0025] The beneficial effects of this invention are as follows: 1. The production line, from aluminum sheet loading, heating, transfer, transportation positioning to rolling, has tightly connected links, realizing fully automated continuous operation. The aluminum sheet automatically enters the electric furnace for heating via a chain conveyor system, the transfer robot automatically completes the transfer of the aluminum sheet, the transportation positioning machine automatically transports and positions the aluminum sheet, and finally the rolling mill automatically completes the rolling. Compared with the traditional manual operation method, it greatly reduces the waiting time and manual handling time between each link, significantly improving production efficiency. 2. The transportation positioning machine is equipped with a centering device, which drives the left and right centering edges to move closer together through a centering drive mechanism, and uses vertical centering rollers to accurately center the aluminum sheet. This ensures that the aluminum sheet is in the correct position when entering the rolling mill, making the rolling process more accurate, improving the dimensional accuracy and consistency of the product, and reducing the defect rate. 3. Using a transfer robot to transfer the aluminum sheet avoids workers directly contacting the high-temperature aluminum sheet, effectively reducing the risk of workers being burned. Meanwhile, the automation of the entire production line reduces the time workers spend in dangerous environments such as high temperature and high pressure, improving work safety. The operational stability and accuracy of automated equipment are far superior to manual operation, effectively avoiding problems such as aluminum plate jamming and tilting caused by human error, reducing the probability of equipment failure and accidents, and ensuring the safety and stability of the production process.

The transport positioning machine 3 is also provided with a front-to-back aluminum plate pusher 25 in the middle. The aluminum plate pusher 25 is equipped with a pusher lifting cylinder 26 to drive the aluminum plate pusher 25 to extend or retract upwards. The aluminum plate pusher 25 is driven by a pusher driving device 27. The pusher driving device 27 is located in the middle of the frame 12 and is not higher than the upper limit of the roller 13. The pusher driving device 27 is a common linear drive unit, such as a pressure cylinder assembly, an electric push rod, or a screw slider assembly. Here, we choose a commercially available electric push rod.

[0039] The rear end of the extension plate 17 is mounted at the inlet of the rolling mill 4; The rolling mill 4 has an upper roller 28 and a lower roller 29. The aluminum plate 11 is brought in from the extension plate 17 between the upper roller 28 and the lower roller 29 to complete the rolling and then exits from the front end of the rolling mill 4.

[0040] Combined with appendix Figure 8 and 9 To facilitate the layout of the aluminum plate pusher 25, the rollers 13 are arranged in two rows, divided into a left roller group 30 and a right roller group 31. The left roller group 30 has a left sprocket 32 ​​at the left end of the roller 13, and a left roller drive motor 33 at the lower end of the left roller group 30.

The right roller group 31 has a right sprocket 35 at the right end of the roller 13, and similarly, the right roller group 31 is driven to rotate by a right roller drive motor 36. With this design, the aluminum plate pusher 25 is installed between the left roller group 30 and the right roller group 31, which can easily maintain the balance in pushing the aluminum plate 11.

[0041] Combined with appendix Figure 3 In a preferred embodiment, the chain system 7 is provided with two conveyor chains 37, one on the left and one on the right. The plate partition 10 is installed on the conveyor chain 37. With the conveyor chain 37 set up in this way, the lower left end of the aluminum plate 11 is supported on the left conveyor chain 37 and the right end is supported on the right conveyor chain 37, so that the aluminum plate 11 can be firmly clamped whether it is in the electric furnace 2 or after it is taken out of the furnace.

[0042] In order to control the temperature, the end of the heating chamber 6 of the electric furnace is provided with a liftable door 38. When the door 38 is lowered, the electric furnace 2 can be sealed.

[0043] Combined with appendix Figure 6 and 7 In order to ensure smooth sliding of the aluminum plate 11, a cover plate 39 is provided above the auxiliary support ball 18. The cover plate 39 is provided with a ball hole 40 corresponding to the auxiliary support ball 18, so that the ball body of the auxiliary support ball 18 protrudes upward from the ball hole 40.

[0044] A preferred layout of an extension plate 17 includes a main plate strip 41 and two rows of side plate strips 42 located on both sides of the main plate strip 41, wherein the roller travel groove 19 is disposed between adjacent side plate strips 42.

[0045] Furthermore, the aluminum plate pusher 25 slides in a pusher stroke groove 43, which is partially located in the middle of the main plate strip 41 of the extension plate 17.

[0046] A preferred embodiment of an assisted support ball 18 includes a ball base and a rotatable ball body 44 embedded in the ball base.

[0047] Combined with appendix Figure 4 In order to facilitate the clamping of aluminum plate 11, the gripper of the transfer manipulator 5 adopts a two-finger cylinder. An extension bar 45 is connected to the finger of the two-finger cylinder, and a friction block 46 is provided on the opposite side of the end of the extension bar 45.

[0048] Combined with appendix Figure 8 and 9 A preferred centering drive mechanism 21 includes a front transverse guide rod 47 and a rear transverse guide rod 48 fixed on the frame 12. An electric actuator drive rail 49 is provided between the front transverse guide rod 47 and the rear transverse guide rod 48. The left centering edge 22 and the right centering edge 23 are slidably mounted on the electric actuator drive rail 49 and are mounted on the front transverse guide rod 47 and the rear transverse guide rod 48. The mechanism also includes two centering edge drive motors 50 that drive the left centering edge 22 and the right centering edge 23 respectively. The left centering edge 22 is composed of a main part 51 that is partially movable on the frame 12 and an extension part 52 that is movable on the extension plate 17. The main part 51 and the extension part 52 are screwed together to form the left centering edge 22. The centering roller 24 on the extension part completes the centering of the aluminum plate 11 on the extension plate 17. The right centering edge 23 is similarly configured.

[0049] In this invention, the pre-treated aluminum plate 11 is placed upright between the plate dividers 10 of the automated conveyor belt system 7. The conveyor belt system 7 has two sets of conveyor chains, left and right. The plate dividers 10 are installed on the conveyor chains, with the lower left end of the aluminum plate 11 resting on the left conveyor chain and the right end resting on the right conveyor chain, thus firmly clamping the aluminum plate 11. The sprocket motor 9 is turned on, driving the sprocket 8 to rotate, thereby driving the chain belt to rotate. The chain belt system 7 partially enters the heating chamber 6 of the electric furnace, and the aluminum plate 11 enters the heating chamber 6 of the electric furnace along with the chain belt for heating. After the aluminum plate 11 has been heated in the electric furnace 2, the transfer robot 5 is activated. The gripper of the transfer robot 5 uses a two-finger cylinder, with extension bars 45 connected to the fingers of the two-finger cylinder. Friction blocks are provided on the opposite surfaces of the ends of the extension bars 45. The friction blocks are used to clamp the aluminum plate 11, transferring the aluminum plate 11 from the outlet of the electric furnace 2 to the transport positioning machine.

[0050] Rollers 13 are arranged on the frame 12 of the transport positioning machine. A left sprocket 32 ​​is located at the left end of the roller 13 in the left roller group 30. The left roller drive motor 33 drives the left roller transmission chain 34, which in turn drives the left sprocket 32, causing the left roller group 30 to rotate. Similarly, a right sprocket 35 is located at the right end of the roller 13 in the right roller group 31, and is driven to rotate by the right roller drive motor 36. An aluminum plate 11 is placed on the rollers 13 and transported forward as the rollers 13 rotate.

[0051] The centering drive mechanism 21 is activated, which drives the left centering edge 22 and the right centering edge 23 to move closer together. The left centering edge 22 and the right centering edge 23 are provided with several vertically arranged centering rollers 24. The rear centering rollers 24 extend from the roller stroke grooves 19 on the extension plate 17, and the front centering rollers 24 extend from the through gaps 14 between adjacent rollers 13 on the frame 12. The centering rollers 24 are used to center the aluminum plate 11 during transportation to ensure that the aluminum plate 11 is in the correct position.

[0052] When the aluminum plate 11 is transported to the middle of the transport positioning machine, the pusher drive device 27 drives the aluminum plate pusher 25, which is installed between the left roller group 30 and the right roller group 31, to push the aluminum plate 11 to continue moving forward to the extension plate 17 part, maintaining the balance of the aluminum plate 11 during the pushing process.

[0053] The rear end of the extension plate 17 of the transport positioning machine is mounted at the inlet of the rolling mill 4. Under the push of the aluminum plate pusher 25, the aluminum plate 11 is carried from the extension plate 17 into the space between the upper roller 28 and the lower roller 29 of the rolling mill 4. The upper roller 28 and the lower roller 29 apply pressure to the aluminum plate to complete the rolling of the aluminum plate 11. The rolled product is output from the front end of the rolling mill 4.

[0054] After the aluminum plate pusher 25 completes one cycle, it is driven downward by the pusher lifting cylinder. The pusher drive device 27 pushes it back to the front end of the aluminum plate 11 above and below the frame, waiting to push the next aluminum plate 11 into the rolling mill, thereby realizing the continuous rolling operation of aluminum plates.

[0055] The beneficial effects of this invention are as follows: 1. The production line, from aluminum sheet loading, heating, transfer, transportation positioning to rolling, has tightly connected links, realizing fully automated continuous operation. The aluminum sheet automatically enters the electric furnace for heating via a chain conveyor system, the transfer robot automatically completes the transfer of the aluminum sheet, the transportation positioning machine automatically transports and positions the aluminum sheet, and finally the rolling mill automatically completes the rolling. Compared with the traditional manual operation method, it greatly reduces the waiting time and manual handling time between each link, significantly improving production efficiency. 2. The transportation positioning machine is equipped with a centering device, which drives the left and right centering edges to move closer together through a centering drive mechanism, and uses vertical centering rollers to accurately center the aluminum sheet. This ensures that the aluminum sheet is in the correct position when entering the rolling mill, making the rolling process more accurate, improving the dimensional accuracy and consistency of the product, and reducing the defect rate. 3. Using a transfer robot to transfer the aluminum sheet avoids workers directly contacting the high-temperature aluminum sheet, effectively reducing the risk of workers being burned. Meanwhile, the automation of the entire production line reduces the time workers spend in dangerous environments such as high temperature and high pressure, improving work safety. The operational stability and accuracy of automated equipment are far superior to manual operation, effectively avoiding problems such as aluminum plate jamming and tilting caused by human error, reducing the probability of equipment failure and accidents, and ensuring the safety and stability of the production process.
