Description

Technical Field

[0001] This application relates to the technical field of flat steel stacking, and in particular to a turntable mechanism and an automatic flat steel stacking system and method using the turntable mechanism. Background Technology

[0002] In the metallurgical and steel processing industry, the traditional flat steel stacking process has long relied on manual operation. Specifically, operators need to use hooks to pick up individual steel pieces from the conveyor chain one by one into a collection trough, and then manually move and stack the steel pieces in the trough into layers to complete the stacking and packaging. This operation mode has the following obvious drawbacks: high labor intensity, with all actions relying on manual labor, which can easily cause muscle strain or work-related injuries to workers; poor stacking quality, with low manual alignment accuracy, resulting in misalignment and tilting of flat steel layers after stacking, leading to an uneven overall stack appearance; low production efficiency, as the rhythm of manually picking up and sorting flat steel piece by piece is affected by the operator's physical strength and skill level, making it impossible to match the pace of continuous production lines, becoming a bottleneck restricting the overall capacity of the rolling line; and low automation, with existing processes lacking mechanized and automated means to achieve automatic stacking of flat steel, making it difficult to meet the efficient, safe, and intelligent production requirements of modern steel rolling workshops.

[0003] In conclusion, traditional manual palletizing methods are no longer suitable for the development trend of large-scale, high-intensity, and continuous production. There is an urgent need for a flat steel palletizing system that can reduce the labor intensity of workers, improve palletizing quality and production efficiency, and achieve automated operation. Summary of the Invention

[0004] To improve the stacking efficiency and flatness of flat steel, this application provides a turntable mechanism and an automatic flat steel stacking system and method using the turntable mechanism.

[0005] In the first aspect, this application provides an automatic flat steel palletizing system, which adopts the following technical solution: An automatic flat steel stacking system includes a first conveying mechanism, a turntable mechanism, a stacking mechanism, and a second conveying mechanism. The first conveying mechanism is used to transfer the flat steel produced in the discharge area to the turntable mechanism. The turntable mechanism is used to transfer the flat steel one by one to the stacking mechanism. The stacking mechanism is used to stack the flat steel one by one. The second conveying mechanism is used to transfer the stacked flat steel. The turntable mechanism includes a first drive motor, a drive shaft, multiple turntable assemblies, and a first base. The first drive motor is mounted on the first base, and the output end of the first drive motor transmits power to the drive shaft. Each turntable assembly includes a first mounting plate and a second mounting plate. For each turntable assembly, the first mounting plate and the second mounting plate are fixedly connected. The drive shaft is fixedly connected to the first mounting plate and the second mounting plate. The first mounting plate includes multiple first lifting ends and multiple first power ends, and the second mounting plate includes multiple second lifting ends. For each of the first lifting ends, a first gear is installed on the first lifting end. The first gear is fixedly connected to a lifting gear shaft. The end of the lifting gear shaft away from the first gear is rotatably connected to the corresponding second lifting end. The lifting gear shaft is fixedly connected to a first support plate. The first support plate is located between the first mounting plate and the second mounting plate. The first support plate extends in a direction parallel to the ground. The first support plate is used to horizontally lift and rotate the flat steel bars one by one so that the flat steel bars are transferred to the stacking mechanism. For each of the turntable components, a second gear is provided on the drive shaft sleeve, and the second gear is fixedly mounted on the first base; For each of the first power ends, the first power end is equipped with an odd number of power transmission gears. If the number of power transmission gears is greater than one, the power transmission gears closer to the first lifting end mesh with the first gear, and the power transmission gears farther away from the first lifting end mesh with the second gear. If the number of power transmission gears is one, the power transmission gear meshes with the first gear and the second gear respectively.

[0006] By adopting the above technical solution, a mechanized flow line for flat steel stacking can be formed through the first conveying mechanism, turntable mechanism, stacking mechanism, and second conveying mechanism. This eliminates the need for workers to manually handle individual flat steel bars, reducing labor intensity and the risk of worker injuries and hook collisions. The turntable mechanism employs a structure of revolution and odd-numbered gear chain rotation, ensuring the first pallet remains horizontal at any angle. This allows for continuous reception and horizontal transport of flat steel, improving the stability of flat steel transport.

[0007] Optionally, the first base is further equipped with multiple transition plates, the upper surfaces of which are flush, and the multiple transition plates are located on the side of the drive shaft away from the first conveying mechanism. For each turntable assembly, a second pallet is fixedly connected to the end of the first pallet near the stacking mechanism, and the extension directions of the first pallet and the second pallet are perpendicular to each other. The first pallets corresponding to the current first lifting end lift and transport the flat steel to the multiple transition plates, and the second pallets corresponding to the next first lifting end push the flat steel on the multiple transition plates onto the stacking mechanism.

[0008] By adopting the above technical solution, the transition plate, acting as a fixed, level buffer platform, allows the flat steel bars to be smoothly placed from the moving first pallet to a stable intermediate position. This eliminates the impact, slippage, or positional deviation that might occur during direct handover, laying the foundation for precise pushing in the next stage. The second pallet is vertically connected to the first pallet. As the turntable assembly continues to rotate, the second pallet contacts the flat steel bars resting on the transition plate from the side and pushes them linearly into the designated position of the stacking mechanism, thus converting rotational power into linear pushing force. The action is smooth and reliable. This ensures that each flat steel bar has a consistent and accurate starting position when entering the stacking station, guaranteeing that each flat steel bar can be neatly stacked to form a regular steel stack. The entire process is synchronized with the rhythm of the turntable assembly, requiring no interruptions, achieving continuous automated production and improving overall stacking efficiency.

[0009] Optionally, the palletizing mechanism includes multiple first lifting plates and multiple first driving components. For each first driving component, the height of the first lifting plate relative to the ground is adjusted based on the height of the flat steel stack on the first lifting plate corresponding to the first driving component, so that multiple second pallets push the flat steel on the multiple transition plates one by one to the first lifting plate. The palletizing mechanism also includes multiple third pallets and multiple second driving components. For each second driving component, the distance between the third pallet and the driving shaft is adjusted based on the width of the flat steel stack on the third pallet corresponding to the second driving component.

[0010] By adopting the above technical solution, the first drive component adjusts the height of the first lifting plate according to the height of the flat steel stack, ensuring that each newly pushed flat steel layer has a consistent and level supporting foundation. This reduces the unevenness that may occur during manual stacking and improves the appearance and quality of the flat steel stack. The second drive component can adjust the distance between the third pallet and the drive shaft (i.e., the extension position of the third pallet), thereby accommodating and transferring flat steel stacks of different widths, enhancing the versatility of the equipment and the flexibility of the production line, while also providing space for the next flat steel stack. The entire flat steel stacking and transfer process is fully automated by each drive component, requiring no manual intervention, reducing the labor intensity of workers, and eliminating safety hazards such as pinching and collisions that may occur during manual stacking.

[0011] Optionally, for each of the third pallets, a first side baffle is hinged to the end of the third pallet away from the drive shaft. The first side baffle abuts against the side surface of the flat steel stack away from the drive shaft. The first side baffle is connected to a third drive assembly, which is used to drive the first side baffle to rotate. The second conveying mechanism includes a plurality of second lifting plates and a plurality of fourth drive assemblies. For each of the fourth drive assemblies, the height of the corresponding second lifting plate relative to the ground is adjusted.

[0012] By adopting the above technical solution, during the stacking and temporary storage of flat steel, the first side baffle provides a stable reference surface for the flat steel stack, reducing the possibility of the flat steel scattering or tilting away from the drive shaft due to vibration or inertia. This ensures the neatness and stability of the entire steel stack, creating favorable conditions for subsequent bundling, transportation, and storage. The entire transfer process of the flat steel stack is fully automated by the third and fourth drive components, requiring no manual intervention and greatly reducing labor intensity.

[0013] Optionally, the palletizing mechanism further includes multiple first push plates and multiple fifth drive components. For each fifth drive component, it is used to drive the corresponding first push plate to move toward the first side baffle. When the first push plate moves into position, the first push plate abuts against the side surface of the flat steel stack away from the first side baffle.

[0014] By adopting the above technical solution, the fifth drive component pushes the first pusher plate towards the flat steel stack until it makes close contact with one side of the stack, while the first side baffle abuts against the other side of the flat steel stack, thereby clamping the entire flat steel stack from both sides. Clamping and tidying the flat steel stack during or after stacking effectively corrects any slight misalignment that may occur. By applying appropriate lateral pressure to the flat steel stack, the possibility of it loosening, tilting, or even collapsing due to vibration or inertia during movement or transfer can be reduced, thus improving operational safety.

[0015] Optionally, the turntable mechanism further includes a second push plate, a first limiting plate, and a sixth driving assembly. The second push plate and the first limiting plate are respectively configured to correspond to the two transition plates at the beginning and end. When the flat steel is transported to the transition plate, the sixth driving assembly drives the second push plate to move towards the transition plate side. The second push plate abuts against one end of the flat steel in the length direction, and the other end of the flat steel abuts against the first limiting plate.

[0016] By adopting the above technical solution, after the flat steel is transported to the transition plate, the sixth drive component pushes the second push plate to move, so that it abuts against one end of the flat steel in the length direction, and pushes the flat steel so that its other end is close to the first limiting plate, thus completing the precise positioning of the flat steel in the length direction. This ensures that the final stack of flat steel is neat and uniform at the ends in the length direction, greatly improving the stack shape quality and aesthetics, and providing a consistent and accurate reference position for subsequent stacking.

[0017] Optionally, the turntable mechanism further includes multiple supports, each of which includes multiple mounting holes. The multiple supports and mounting holes are distributed along the length direction of the flat steel. The first limiting plate is fixedly connected to the mounting hole corresponding to the target position, and the target position corresponds to the length of the flat steel currently being stacked.

[0018] By adopting the above technical solution, the first limiting plate is installed on the support using bolts and other fasteners. When processing flat steel of different lengths, simply loosen the bolts, move the first limiting plate to the mounting hole at the target position that matches the current length of the flat steel, and then retighten it. This allows the system to adapt to the production of flat steel of various lengths, greatly improving the flexibility and adaptability of the production line.

[0019] Optionally, the first conveying mechanism includes a chain assembly, the end of which near the drive shaft is fixedly connected to a mounting groove, and a plurality of second limiting plates are inserted into the mounting groove, the plurality of second limiting plates being distributed along the direction of conveying the flat steel on the chain assembly.

[0020] By adopting the above technical solution, the chain conveyor assembly is responsible for conveying the flat steel from upstream. At its end, near the turntable mechanism, there is an installation groove, in which multiple second limiting plates are inserted. The number of second limiting plates can be adjusted according to the width of the flat steel, forming an adjustable guide channel, allowing the chain conveyor assembly to deliver the flat steel to the turntable mechanism one by one.

[0021] Secondly, this application provides an automatic flat steel stacking method using the automatic flat steel stacking system of the first aspect, employing the following technical solution: An automatic flat steel stacking method using the first aspect of the automatic flat steel stacking system includes: Based on the rotation parameters of the turntable mechanism, the corresponding conveying speed of the first conveying mechanism is obtained, so that the first conveying mechanism can convey the flat steel produced in the discharge area according to the conveying speed. When the flat steel is transferred to the transfer area corresponding to the turntable mechanism, the first drive motor in the turntable mechanism is started, so that the first drive motor drives multiple turntable components to rotate synchronously through the drive shaft, and multiple first pallets horizontally lift and rotate to transport the flat steel to the stacking mechanism. The stacking mechanism is controlled to stack flat steel bars one by one. When the stack of flat steel bars on the stacking mechanism reaches the transfer condition, the stacked flat steel bars are transferred to the second transfer mechanism, and the stacked flat steel bars are transferred based on the second transfer mechanism.

[0022] Thirdly, this application provides a turntable mechanism for flat steel transfer, employing the following technical solution: A turntable mechanism for transferring flat steel includes a first drive motor, a drive shaft, multiple turntable assemblies, and a first base. The first drive motor is mounted on the first base, and its output end transmits power to the drive shaft. Each turntable assembly includes a first mounting plate and a second mounting plate. For each turntable assembly, the first mounting plate and the second mounting plate are fixedly connected. The drive shaft is fixedly connected to the first mounting plate and the second mounting plate. The first mounting plate includes multiple first lifting ends and multiple first power ends, and the second mounting plate includes multiple second lifting ends. For each of the first lifting ends, a first gear is installed on the first lifting end, the first gear is fixedly connected to a lifting gear shaft, the end of the lifting gear shaft away from the first gear is rotatably connected to the corresponding second lifting end, the lifting gear shaft is fixedly connected to a first support plate, the first support plate is located between the first mounting plate and the second mounting plate, the first support plate extends in a direction parallel to the ground, and the first support plate is used to horizontally lift and rotate the flat steel bars one by one for transport. For each of the turntable components, a second gear is provided on the drive shaft sleeve, and the second gear is fixedly mounted on the first base; For each of the first power ends, the first power end is equipped with an odd number of power transmission gears. If the number of power transmission gears is greater than one, the power transmission gears closer to the first lifting end mesh with the first gear, and the power transmission gears farther away from the first lifting end mesh with the second gear. If the number of power transmission gears is one, the power transmission gear meshes with the first gear and the second gear respectively. Attached Figure Description

[0033] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0034] The present application is further described in detail below with reference to the accompanying drawings.

[0035] This application provides an automatic flat steel palletizing system, such as... Figure 1 As shown, it includes a first conveying mechanism 1, a turntable mechanism 2, a stacking mechanism 3, and a second conveying mechanism 4; the first conveying mechanism 1 is used to convey the flat steel produced in the discharge area to the turntable mechanism 2; the turntable mechanism 2 is used to transfer the flat steel one by one to the stacking mechanism 3; the stacking mechanism 3 is used to stack the flat steel one by one; the second conveying mechanism 4 is used to transfer the stacked flat steel.

[0036] like Figures 1 to 3 As shown, the turntable mechanism 2 includes a first drive motor 21, a drive shaft 22, multiple turntable assemblies 23, and a first base 24. The first drive motor 21 is mounted on the first base 24, and the output end of the first drive motor 21 transmits power to the drive shaft 22. Each turntable assembly 23 includes a first mounting plate 231 and a second mounting plate 232. For each turntable assembly 23, the first mounting plate 231 and the second mounting plate 232 are fixedly connected. The drive shaft 22 is fixedly connected to the first mounting plate 231 and the second mounting plate 232. The first mounting plate 231 includes multiple first lifting ends and multiple first power ends, and the second mounting plate 232 includes multiple second lifting ends.

[0037] For each of the first lifting ends, a first gear 5 is installed on the first lifting end. The first gear 5 is fixedly connected to a lifting gear shaft 51. The end of the lifting gear shaft 51 away from the first gear 5 is rotatably connected to the corresponding second lifting end. The lifting gear shaft 51 is fixedly connected to a first support plate 52. The first support plate 52 is located between the first mounting plate 231 and the second mounting plate 232. The first support plate 52 extends in a direction parallel to the ground. The first support plate 52 is used to horizontally lift and rotate the flat steel bars one by one so that the flat steel bars are transferred to the stacking mechanism 3.

[0038] For each of the turntable assemblies 23, a second gear 6 is fitted around the drive shaft 22, and the second gear 6 is fixedly mounted on the first base 24.

[0039] For each of the first power ends, the first power end is equipped with an odd number of power transmission gears 61. If the number of power transmission gears 61 is greater than one, the power transmission gear 61 closer to the first lifting end meshes with the first gear 5, and the power transmission gear 61 farther away from the first lifting end meshes with the second gear 6. If the number of power transmission gears 61 is one, the power transmission gear 61 meshes with the first gear 5 and the second gear 6 respectively.

[0040] In this embodiment, the first conveying mechanism 1 is responsible for transporting flat steel from upstream production lines (such as hot-rolled or cold-rolled flat steel production lines, straighteners, or shearing machines) to the receiving station of the turntable mechanism 2. The turntable mechanism 2 is one of the core innovations of this system; its function is to transfer the flat steel received from the first conveying mechanism 1 one by one to the stacking mechanism 3 in a smooth and continuous manner. The stacking mechanism 3 is responsible for receiving the flat steel from the turntable mechanism 2 and stacking it layer by layer into a stack. The second conveying mechanism 4 is used to receive the complete stack of flat steel transferred from the stacking mechanism 3 and transport it to the next location (such as a bundling station or warehouse storage area).

[0041] The first base 24 may include a motor mounting base 241 and a tilting machine base 242, which are respectively fixed to the ground. A first drive motor 21 can be fixedly mounted on the motor mounting base 241 via a flange or bolts. Its output end can be connected to the drive shaft 22 via a coupling to provide power to the entire turntable mechanism 2. The first drive motor 21 can be a servo motor. A fixed gear seat 243 is mounted on the upper surface of the tilting machine base 242 away from the ground. The drive shaft 22 can be mounted on the fixed gear seat 243 by a bearing housing, and the drive shaft 22 is rotatably connected to the fixed gear seat 243.

[0042] Each turntable assembly 23 is formed by a first mounting plate 231 and a second mounting plate 232 fixedly connected together, creating a robust frame structure. A drive shaft 22 passes through the center holes of the first and second mounting plates 231 and is fixedly connected to them via a keyway, allowing the turntable assembly 23 to rotate together with the drive shaft 22. In this embodiment, the first and second mounting plates 231 and 232 may have the same shape, and a gap is provided between them.

[0043] The first mounting plate 231 has a plurality of first lifting ends and first power ends evenly distributed on its circumference. The second mounting plate 232 has second lifting ends at positions corresponding to the first lifting ends of the first mounting plate 231, and second power ends at positions corresponding to the first power ends of the first mounting plate 231. In this embodiment, the first mounting plate 231 may have four first lifting ends, and the second mounting plate 232 may have four second lifting ends.

[0044] On each first lifting end, a first gear 5 is mounted via a bearing. The first gear 5 is fixedly connected to a lifting gear shaft 51, and the other end of the lifting gear shaft 51 is rotatably connected to the corresponding second lifting end on the second mounting plate 232 via a bearing. A first support plate 52 is fixedly mounted on the side wall of the lifting gear shaft 51, located in the gap between the first mounting plate 231 and the second mounting plate 232, and the surface of the first support plate 52 away from the lifting gear shaft 51 protrudes from the first mounting plate 231 and the second mounting plate 232. In the initial position before the drive shaft 22 starts to rotate, each first support plate 52 can be in a horizontal posture parallel to the ground. When the drive shaft 22 starts to rotate, each first support plate 52 can always maintain a horizontal posture parallel to the ground, thereby horizontally lifting the flat steel and maintaining a horizontal posture to transport the flat steel during rotation.

[0045] On each first power end, several power transmission gears 61 are mounted via shafts and bearings. Crucially, the number of power transmission gears 61 on each first power end is odd, ensuring the correct transmission of motion.

[0046] Each turntable assembly 23 also includes a second gear 6 sleeved on the outside of the drive shaft 22. The second gear 6 is fixed and does not rotate, that is, it does not rotate with the rotation of the drive shaft 22. The second gear 6 can be mounted on the fixed gear seat 243 by a bracket or directly fixed.

[0047] In this embodiment, the second gear 6 is identical to each of the first gears 5. Specifically, the second gear 6 and each of the first gears 5 have the same basic meshing parameters, geometric dimensions, and material and process parameters. The basic meshing parameters may include the gear module and pressure angle, the geometric dimensions may include the number of teeth and tooth width, and the material and process parameters may include the gear material, heat treatment process, and manufacturing process. The power transmission gear 61 may also be the same as the first gear 5 and the second gear 6.

[0048] For each turntable assembly 23, on each of its first power ends, when the number of power transmission gears 61 is an odd number greater than 1, multiple power transmission gears 61 are sequentially meshed to form a transmission chain. In this transmission chain, the power transmission gear 61 closer to the first lifting end meshes with the first gear 5, and the power transmission gear 61 farther from the first lifting end meshes with the fixed second gear 6. When the number of power transmission gears 61 is 1, the power transmission gear 61 meshes with both the first gear 5 and the second gear 6.

[0049] When the first drive motor 21 starts, it drives the drive shaft 22 to rotate, which in turn drives all the turntable assemblies 23 to revolve around it. Since the power transmission gear 61 at the end of each first power end meshes with the fixed second gear 6, the revolving motion of the turntable assembly 23 causes these end power transmission gears 61 to rotate around the second gear 6. Due to the gear meshing, the "revolving" motion of the end gears causes the entire gear transmission chain to rotate within the first power end. Because the gear transmission chain consists of an odd number of power transmission gears 61, when the motion is finally transmitted to the first gear 5, it causes the first gear 5 to rotate in the opposite direction to the revolution of the drive shaft 22, but at the same speed. The rotation of the first gear 5 is transmitted to the first support plate 52 through the lifting gear shaft 51, ensuring that the first support plate 52 maintains an absolutely horizontal posture while revolving with the turntable assembly 23.

[0050] like Figure 2 and Figure 3 As shown in this embodiment, for each first mounting plate 231, a gear cover 233 is sleeved on the outside of the first lifting end and the first power end corresponding to the first mounting plate 231, and the gear cover 233 is fixedly connected to the first mounting plate 231.

[0051] The first conveying mechanism 1, the turntable mechanism 2, the stacking mechanism 3, and the second conveying mechanism 4 form a mechanized streamline for flat steel stacking, eliminating the need for workers to manually handle individual flat steel bars, reducing labor intensity, worker injuries during handling, and the risk of hook collisions. The turntable mechanism 2 employs a structure of revolution and odd-numbered gear chain rotation, ensuring that the first pallet 52 remains horizontal at any angle. This allows for continuous reception of flat steel bars and completes horizontal transport, improving the stability of flat steel transport.

[0052] like Figure 1 and Figure 2 As shown, in this embodiment, the drive shaft 22 may include a driving shaft and multiple driven shafts. The driving shaft is connected to the first drive motor 21, and the multiple driven shafts are connected end to end in sequence through a coupling to form a driven shaft body. One end of one of the driven shafts in the driven shaft body is connected to the end of the driving shaft away from the first drive motor 21 through a coupling, so as to realize the synchronous driving of the driving shaft to the multiple driven shafts.

[0053] Based on the length of the flat steel to be stacked, calculate the number of turntable assemblies 23 required for operation. Each turntable assembly 23 requires power from a drive shaft 22. Based on this number, the total length of the required drive shafts 22 can be determined. Then, by increasing or decreasing the number of driven shafts connected by couplings, drive shafts 22 of the required length can be flexibly assembled.

[0054] For the turntable assembly 23 that does not need to participate in the current flat steel stacking work, its corresponding driven shaft can be disconnected from the active shaft, so that the driven shaft and turntable assembly 23 will not rotate with the first drive motor 21, thereby avoiding unnecessary idling and significantly reducing energy loss caused by mechanical friction.

[0055] like Figures 1 to 3 As shown, in this embodiment, a plurality of transition plates 7 are also installed on the first base 24. The upper surfaces of the plurality of transition plates 7 are flush with each other, and the plurality of transition plates 7 are respectively located on the side of the drive shaft 22 away from the first conveying mechanism 1. For each turntable assembly 23, a second pallet 53 is fixedly connected to the end of the first pallet 52 near the end of the stacking mechanism 3. The extension direction of the first pallet 52 and the extension direction of the second pallet 53 are perpendicular to each other. The first pallets 52 corresponding to the plurality of current first lifting ends lift and transport the flat steel to the plurality of transition plates 7, and the second pallets 53 corresponding to the plurality of next first lifting ends push the flat steel on the plurality of transition plates 7 onto the stacking mechanism 3.

[0056] Multiple transition plates 7 and multiple turntable assemblies 23 are staggered. When a certain first lifting end rotates to the position furthest from the first conveying mechanism 1 (i.e. Figure 3 The first lifting end is located on the right side near the transition plate 7. The end face of the first support plate 52 corresponding to the first lifting end that is close to the drive shaft 22 can be named the first end face. The end face of the first support plate 52 corresponding to the first lifting end that is far away from the drive shaft 22 can be named the second end face. For each transition plate 7, the end face of the transition plate 7 that is close to the drive shaft 22 can be named the third end face. The end face of the transition plate 7 that is far away from the drive shaft 22 can be named the fourth end face. The end face of the second support plate 53 corresponding to the first lifting end that is far away from the drive shaft 22 can be named the fifth end face.

[0057] The distance between the first end face and the vertical plane of the axis of the drive shaft 22 is the first distance, the distance between the second end face and the vertical plane of the axis of the drive shaft 22 is the second distance, the distance between the third end face and the vertical plane of the axis of the drive shaft 22 is the third distance, and the distance between the fourth end face and the vertical plane of the axis of the drive shaft 22 is the fourth distance. The first distance is greater than the third distance, and the second distance is less than the fourth distance. This allows the flat steel supported by the first pallet 52 to be transferred to the transition plate 7 when the first pallet 52 rotates to the transition plate 7 and continues to rotate.

[0058] The distance between the fifth end face and the vertical plane of the axis of the drive shaft 22 is the fifth distance. The fourth distance is less than the fifth distance, so that the second pallet 53 corresponding to the next first lifting end can gradually push the flat steel on the transition plate 7 away from the drive shaft 22 as the first lifting end rotates, so that the flat steel can move from each transition plate 7 to the stacking mechanism 3. It is easy to understand that the next first lifting end is the first lifting end that rotates to the transition plate 7 next along the rotation direction of the first mounting plate 231 and the second mounting plate 232.

[0059] like Figures 1 to 3 As shown, the height of the upper surface of the transition plate 7 gradually decreases from the end near the drive shaft 22 to the end away from the drive shaft 22, forming an inclined surface on the upper surface of the transition plate 7. This inclined surface can utilize the weight component of the flat steel itself to assist the second support plate 53 in pushing the flat steel towards the stacking mechanism 3, thereby making the pushing of the flat steel towards the stacking mechanism 3 on the transition plate 7 more effortless and smoother. For example, the upper surface of the transition plate 7 can be lowered by 0.5 degrees to 1.5 degrees in the direction away from the drive shaft 22.

[0060] In this embodiment, the first pallet 52, the second pallet 53, and the transition plate 7 can be plates with good wear resistance, moderate hardness, and resistance to deformation, respectively. This ensures that the surface of the flat steel is protected while maintaining its stability during long-term use. For example, the first pallet 52 and the second pallet 53 can be made of metal materials that have undergone surface treatments such as chrome plating or quenching, giving them advantages such as high strength, wear resistance, long service life, and resistance to deformation.

[0061] The flat steel moves towards the stacking mechanism 3 via the first support plate 52, the second support plate 53, and the transition plate 7, achieving a sliding and pushing motion throughout the process. This prevents it from falling freely and reduces the possibility of surface impact or edge damage to the flat steel.

[0062] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in this embodiment, the palletizing mechanism 3 includes multiple first lifting plates 31 and multiple first driving components 32. For each first driving component 32, the height of the first lifting plate 31 relative to the ground is adjusted based on the height of the flat steel stack on the first lifting plate 31 corresponding to the first driving component 32, so that multiple second pallets 53 push the flat steel on the multiple transition plates 7 one by one to the first lifting plate 31. The palletizing mechanism 3 also includes multiple third pallets 33 and multiple second driving components 34. For each second driving component 34, the distance between the third pallet 33 and the driving shaft 22 is adjusted based on the width of the flat steel stack on the third pallet 33 corresponding to the second driving component 34.

[0063] The core function of the palletizing mechanism 3 is to receive flat steel bars and stack them one by one, while performing a series of automatic adjustment operations during and after the stacking process.

[0064] In the initial lifting state, for each of the first drive components 32, the height of the first lifting plate 31 corresponding to that first drive component 32 is adjusted so that the upper surface of the first lifting plate 31 is not higher than the upper surface of the corresponding transition plate 7. It is easy to understand that the initial lifting state is the state in which there is no flat steel on the first lifting plate 31.

[0065] During subsequent flat steel transfer, for each of the first drive components 32, the height of the first lifting plate 31 corresponding to that first drive component 32 is adjusted according to the current height of the flat steel stack, so that the upper surface of the current flat steel stack is not higher than the upper surface of the corresponding transition plate 7; the height of the first lifting plate 31 is higher than the height of the third support plate 33. It is easy to understand that the subsequent flat steel transfer state is the state where flat steel exists on the first lifting plate 31.

[0066] If the number of flat steel bars in the current flat steel stack on the first lifting plate 31 reaches a preset threshold, the turntable mechanism 2 is controlled to pause the transfer of flat steel bars. For each first drive component 32, the height of the first lifting plate 31 corresponding to the first drive component 32 is adjusted so that the upper surface of the first lifting plate 31 is lower than the height of the corresponding third support plate 33, and the third support plate 33 lifts the current flat steel stack. For each second drive component 34, the distance between the third support plate 33 corresponding to the second drive component 34 and the drive shaft 22 is adjusted so that the width of the empty space on the upper surface of the third support plate 33 near the end of the drive shaft 22 is not less than the width of the flat steel bars. Based on the corresponding first drive component 32, the height of the first lifting plate 31 is adjusted to the initial lifting state.

[0067] The turntable mechanism 2 places flat steel bars onto multiple transition plates 7. Subsequently, the second support plate 53 of the turntable mechanism 2 pushes the flat steel bars on the transition plates 7 to the stacking station. In the initial lifting state, the upper surface of the first lifting plate 31 is slightly lower than or equal to the upper surface of the transition plates 7 to facilitate the pushing of the flat steel bars. The first drive assembly 32 can be a servo motor-driven lead screw 343 lifting mechanism or a hydraulic cylinder, used to precisely control the height of the first lifting plate 31. Whenever a new flat steel bar is pushed onto the current flat steel stack, the first drive assembly 32 drives the first lifting plate 31 to descend by the thickness of one flat steel bar, ensuring that the upper surface of the current flat steel stack is always no higher than the upper surface of the transition plates 7, creating conditions for the smooth pushing of the next flat steel bar.

[0068] The real-time height H of the first lifting plate 31 can be controlled in a closed loop by the first drive component 32 to achieve dynamic height tracking with the flat steel stack and to lower and lower the plate accordingly.

[0069] The real-time height H of the first lifting plate 31 can be expressed as: H=H0-Σti-k Where H0 represents the height of the transition plate 7, ti represents the thickness of the i-th flat steel bar currently stacked in the flat steel stack, and k represents the distance constant, for example, k can be 2mm. Ensuring that the top of the current flat steel stack is lower than the transition plate 7 allows the next flat steel bar to be horizontally pushed into the current flat steel stack by the second support plate 53, reducing the possibility of impact.

[0070] When the stack of flat steel bars on the first lifting plate 31 reaches a preset threshold number, the turntable mechanism 2 can be controlled to pause the individual transport of flat steel bars. The first drive assembly 32 drives the first lifting plate 31 to descend until its upper surface is lower than the upper surface of the third support plate 33. At this time, the weight of the entire stack of flat steel bars is supported by the third support plate 33. The second drive assembly 34 can be a linear module or a cylinder, and can drive the third support plate 33 to move horizontally. The third support plate 33 moves a short distance away from the drive shaft 22, creating a gap between its end and the stack of flat steel bars that is not less than the width of a single flat steel bar, preparing for receiving the next stack of flat steel bars. At the same time, the first lifting plate 31 rises back to its initial height, ready to start the next stacking cycle.

[0071] When the number of flat steel stacks reaches a preset threshold, the first drive component 32 lowers the first lifting plate 31 by Δh, making H < H3 (H3 is the height of the third support plate 33). The weight of the entire flat steel stack is instantly transferred to the third support plate 33; the first lifting plate 31 is reset under no-load, completing the handover of the flat steel stacks and reducing the possibility of the flat steel stacks collapsing due to loss of support during the exchange. In this embodiment, the threshold can be represented as N, and N can be 40. Under the action of the second drive component 34, the third support plate 33 can be moved outward by ΔL, where ΔL can be represented as ΔL = flat steel width + 10mm, forming a receiving notch for the flat steel, allowing the next flat steel to fall directly into the notch.

[0072] In this embodiment, for each of the third pallets 33, a first side baffle 35 is hinged to the end of the third pallet 33 away from the drive shaft 22. The first side baffle 35 abuts against the side surface of the flat steel stack away from the drive shaft 22. The first side baffle 35 is connected to a third drive assembly 36, which is used to drive the first side baffle 35 to rotate. like Figure 1 and Figure 6As shown, the second conveying mechanism 4 includes a plurality of second lifting plates 41 and a plurality of fourth drive components 42. For each of the fourth drive components 42, the height of the corresponding second lifting plate 41 relative to the ground is adjusted.

[0073] like Figure 1 , Figure 5 and Figure 6 As shown, when the flat steel stack on the third pallet 33 reaches the transfer condition, for each second drive assembly 34, the distance between the third pallet 33 and the drive shaft 22 corresponding to the second drive assembly 34 is adjusted until the flat steel stack is above the corresponding second lifting plate 41. For each fourth drive assembly 42, the height of the second lifting plate 41 corresponding to the fourth drive assembly 42 is adjusted so that the second lifting plate 41 is higher than the third pallet 33, and the second lifting plate 41 lifts the flat steel stack. For each third drive assembly 36, the first side baffle 35 corresponding to the third drive assembly 36 is rotated to a horizontal state, and the second drive assembly 34 is controlled to drive the third pallet 33 back.

[0074] At the far end of each third pallet 33 (i.e., the end furthest from the drive shaft 22), a first side baffle 35 is hinged. In the stacking and storage state, the third drive assembly 36 (such as a small cylinder) keeps it upright, abutting against the side surface of the flat steel stack, reducing the possibility of the flat steel stack becoming scattered.

[0075] The second conveying mechanism 4 includes multiple second bases 43, and a fourth drive assembly 42 is fixedly installed on the corresponding second base 43. The fourth drive assembly 42 may include a cylinder. The second lifting plate 41 abuts against the upper surface of the second base 43. The second base 43 also includes a second side baffle 44, which is located on the side of the second lifting plate 41 away from the turntable mechanism 2. When the flat steel stack is transferred from the third pallet 33 to the second lifting plate 41, the side surface of the flat steel stack away from the turntable mechanism 2 abuts against the second side baffle 44, reducing the possibility of the flat steel stack scattering.

[0076] Each second drive assembly 34 may include a slide 341, a trolley bracket 342, a lead screw 343, and a lead screw 343 female seat. The lead screw 343 female seat is fixedly installed on the bottom surface of the slide 341, and the lead screw 343 female seat is threadedly engaged with the lead screw 343. The trolley bracket 342 is fixedly connected to the upper surface of the slide 341, and the third support plate 33 can be installed on the upper surface of the trolley bracket 342. The lead screw 343 extends along the conveying direction of the flat steel stack from the third support plate 33 to the second lifting plate 41. The stacking mechanism 3 also includes a second drive motor 37 and multiple spiral bevel gear commutators 371. The ends of the multiple lead screws 343 near the second lifting plate 41 are respectively connected to the corresponding spiral bevel gear commutators 371. The second drive motor 37 transmits power synchronously to the multiple lead screws 343 through the multiple spiral bevel gear commutators 371. As the lead screw 343 rotates, the slide 341 can drive the third support plate 33 to move closer to or further away from the second lifting plate 41. In this embodiment, multiple lead screws 343 are staggered with multiple second bases 43, that is, multiple lead screws 343 can be located between two second bases 43 respectively.

[0077] like Figure 5 As shown in this embodiment, the palletizing mechanism 3 further includes a plurality of first push plates 38 and a plurality of fifth drive components 381. For each of the fifth drive components 381, it is used to drive the corresponding first push plate 38 toward the first side baffle 35. When the first push plate 38 moves into position, the first push plate 38 abuts against the side surface of the flat steel stack away from the first side baffle 35.

[0078] Multiple first push plates 38 are respectively arranged adjacent to multiple first side baffles 35. For example, the multiple first push plates 38 can be fixedly connected to the trolley bracket 342 of the corresponding first side baffle 35. The first push plates 38 are driven by a fifth drive assembly 381 (such as a cylinder) and can move toward the plane where the first side baffle 35 is located. During or after the current flat steel stack is stacked, the first push plates 38 can extend and cooperate with the first side baffles 35 to clamp the flat steel stack from both sides, further ensuring the neatness of the stack shape.

[0079] When the flat steel stack on the third pallet 33 reaches the transfer condition, the fifth drive assembly 381 can also drive the first push plate 38 to extend and keep the first push plate 38 in contact with the side of the flat steel stack away from the first side baffle 35 until the flat steel stack is transferred from the third pallet 33 to the second lifting plate 41. The fifth drive assembly 381 drives the first push plate 38 to reset, thereby improving the stability of the flat steel stack when it is transferred to the second lifting plate 41.

[0080] like Figure 1 , Figure 4 and Figure 7As shown, in this embodiment, the turntable mechanism 2 further includes a second push plate 25, a first limiting plate 26, and a sixth driving component 27. The second push plate 25 and the first limiting plate 26 are respectively arranged corresponding to the two transition plates 7 at the beginning and end. When the flat steel is transported to the transition plate 7, the sixth driving component 27 drives the second push plate 25 to move towards the transition plate 7. The second push plate 25 abuts against one end of the flat steel in the length direction, and the other end of the flat steel abuts against the first limiting plate 26 in the length direction.

[0081] The second push plate 25 can be located outside the first end transition plate 7 (closer to the first drive motor 21 side), and is horizontally driven by the sixth drive assembly 27 (such as a cylinder or servo electric cylinder), with the movement direction parallel to the length direction of the flat steel. The first limit plate 26 is located outside the tail end transition plate 7 (away from the first drive motor 21 side).

[0082] The pushing process of the second pusher plate 25 on the flat steel can be represented as follows: When the flat steel is unloaded from the first pallet 52 to the transition plate 7, a "positioning" signal can be given by a laser sensor; The sixth drive assembly 27 is immediately launched, and the second pusher plate 25 can push the flat steel to the tail end at a speed of 50 mm / s; When the rear end face of the flat steel contacts the first limiting plate 26, after the pressure relay in the first limiting plate 26 detects 0.3MPa, the sixth drive assembly 27 can hold for 0.5s to complete the clamping of the flat steel with the first limiting plate 26. A control signal is sent to the turntable mechanism 2 to allow rotation. The turntable mechanism 2 continues to rotate, and the second pallet 53 enters the pushing phase. The sixth drive assembly 27 returns to its original position, waiting for the next flat steel.

[0083] Flat steel may slip due to inertia during transport, and the incoming flat steel may also be in different positions. In order to improve the neatness of the flat steel stack, the second push plate 25 can be used to "force zero" each flat steel, so that the reference of the tail of each flat steel is uniform, and the flatness of both ends after stacking meets the preset flatness requirements, which can save the amount of manual double edge alignment work.

[0084] In this embodiment, the first lifting plate 31, the third support plate 33, the first side baffle 35, the first lifting plate 31, the first push plate 38, and the second push plate 25 can also be plates with good wear resistance, moderate hardness, and are not easily deformed, such as metal materials that have undergone surface treatments such as chrome plating or quenching.

[0085] In this embodiment, the turntable mechanism 2 further includes multiple supports 28, each of which includes multiple mounting holes 281. The multiple supports 28 and the multiple mounting holes 281 are distributed along the length direction of the flat steel. The first limiting plate 26 is fixedly connected to the mounting hole 281 corresponding to the target position. The target position corresponds to the length of the flat steel currently being stacked.

[0086] A support 28 is installed at fixed intervals along the length of the flat steel. Multiple supports 28 can be arranged between the two transition plates 7 at the beginning and end, covering the entire length of the flat steel from 3 to 12 meters. Each support 28 has multiple mounting holes 281, with a lateral hole spacing of 50 mm, forming an equidistant hole matrix along the entire line. In this embodiment, each of the two sides at the bottom of the first limiting plate 26 has two vertically arranged mounting points. Therefore, four mounting holes 281 at corresponding positions can be selected according to the length of the flat steel to fix the first limiting plate 26.

[0087] like Figure 1 , Figure 2 and Figure 8 As shown, in this embodiment, the first conveying mechanism 1 includes a chain assembly. The end of the chain assembly near the drive shaft 22 is fixedly connected to a mounting groove 11. A plurality of second limiting plates 12 are inserted into the mounting groove 11. The plurality of second limiting plates 12 are distributed along the direction of conveying the flat steel on the chain assembly.

[0088] The chain conveyor assembly is the core power component of the first conveyor mechanism 1. Driven by a motor, the chain conveyor assembly continuously transports flat steel from the upstream discharge area to the turntable mechanism 2. The chain conveyor assembly offers advantages such as stable conveying and high load-bearing capacity, making it suitable for transporting flat steel.

[0089] At the end of the chain assembly near the drive shaft 22 (i.e., the receiving end that will enter the turntable mechanism 2), a mounting groove 11 is fixedly connected. The mounting groove 11 can be a section of steel or a specially made groove extending along the conveying direction. The function of the mounting groove 11 is to provide a uniform and stable mounting base for the second limiting plate 12.

[0090] Multiple second limiting plates 12 can be fixed in the mounting slot 11 by plugging in. The multiple second limiting plates 12 are distributed from the slot wall of the mounting slot 11 near the turntable mechanism 2 and away from the turntable mechanism 2. The number of second limiting plates 12 in the multiple mounting slots 11 is the same.

[0091] In this embodiment, when the first pallet 52 rotates to the position furthest from the palletizing mechanism 3 (i.e. Figure 3The sixth distance between the end face of the chain assembly near the drive shaft 22 and the vertical plane of the drive shaft 22 axis is less than the seventh distance between the end face of the first pallet 52 away from the drive shaft 22 and the vertical plane of the drive shaft 22 axis; the eighth distance between the side of the second limiting plate 12 away from the stacking mechanism 3 in the mounting groove 11 and the vertical plane of the drive shaft 22 axis is less than the ninth distance between the end face of the first pallet 52 away from the drive shaft 22 and the vertical plane of the drive shaft 22 axis, and the difference between the ninth distance and the eighth distance is not less than the width of the flat steel currently being transported, and less than twice the width of the flat steel currently being transported.

[0092] The number of second limiting plates 12 is adjustable. The operator can flexibly adjust the number of second limiting plates 12 in each mounting slot 11 according to the width specifications of the flat steel being conveyed. This allows for dynamic adjustment of the eighth distance, forming a guide channel with variable width that matches the width of the flat steel, thus enabling the flat steel to be transferred to the turntable mechanism 2 one by one.

[0093] Based on the same technical concept, embodiments of this application also provide an automatic flat steel stacking method, such as... Figure 9 As shown, an automatic flat steel stacking method mainly includes: Step S101: Based on the rotation parameters of the turntable mechanism, obtain the corresponding conveying speed of the first conveying mechanism, so that the first conveying mechanism conveys the flat steel produced in the discharge area according to the conveying speed. Step S102: When the flat steel is transferred to the transfer area corresponding to the turntable mechanism, the first drive motor in the turntable mechanism is started so that the first drive motor drives multiple turntable components to rotate synchronously through the drive shaft, and multiple first pallets horizontally lift and rotate to transport the flat steel to the stacking mechanism. Step S103: Control the stacking mechanism to stack the flat steel one by one. When the stack of flat steel on the stacking mechanism reaches the transfer condition, the stacked flat steel is transferred to the second transfer mechanism, and the stacked flat steel is transferred based on the second transfer mechanism.

[0094] In this embodiment, controlling the stacking mechanism to stack the flat steel bars one by one can specifically include: Based on the current height of the flat steel stack, adjust the height of multiple first lifting plates in the stacking mechanism so that the upper surface of the current flat steel stack is not higher than the upper surface of the corresponding transition plate, and the flat steel is stacked on the first lifting plate. If the number of flat steel bars in the current flat steel stack on the first lifting plate reaches the preset number threshold, the turntable mechanism is controlled to pause the transfer of flat steel bars, and based on the first height adjustment command, the first height of the upper surface of the first lifting plate is adjusted to the first target position. The first target position is the position when the height of the upper surface of the first lifting plate is lower than the height of the corresponding third pallet. Based on the first lateral adjustment command, the third pallet is controlled to move to the second target position. The second target position is the position where the width of the empty space on the upper surface of the end of the third pallet near the drive shaft is not less than the width of the flat steel. Based on the corresponding first drive component, adjust the height of the first lifting plate to the initial lifting state.

[0095] In this embodiment, when the flat steel stack on the palletizing mechanism reaches the transfer condition, the flat steel stack that has completed the palletizing process is transferred based on the second conveying mechanism, which may specifically include: For each second drive assembly, the distance between the third support plate and the drive shaft corresponding to the second drive assembly is adjusted. The fifth drive assembly drives the first push plate to extend and keeps the first push plate in contact with the side of the flat steel stack away from the first side baffle until the flat steel stack is above the corresponding second lifting plate. For each fourth drive assembly, adjust the height of the second lifting plate corresponding to the fourth drive assembly so that the second lifting plate is higher than the third support plate, and the second lifting plate lifts the flat steel stack; For each third drive component, the first side baffle corresponding to the third drive component is rotated to a horizontal state, the fifth drive component drives the first push plate to reset, and controls the second drive component to drive the third support plate back.

[0096] Based on the same technological concept, such as Figure 2 and Figure 3 As shown in the figure, this application embodiment also provides a flat steel conveying turntable mechanism, including a first drive motor 21, a drive shaft 22, a plurality of turntable assemblies 23 and a first base 24. The first drive motor 21 is mounted on the first base 24, and the output end of the first drive motor 21 transmits power to the drive shaft 22. Each turntable assembly 23 includes a first mounting plate 231 and a second mounting plate 232. For each turntable assembly 23, the first mounting plate 231 and the second mounting plate 232 are fixedly connected. The drive shaft 22 is fixedly connected to the first mounting plate 231 and the second mounting plate 232. The first mounting plate 231 includes a plurality of first lifting ends and a plurality of first power ends, and the second mounting plate 232 includes a plurality of second lifting ends. For each of the first lifting ends, a first gear 5 is installed on the first lifting end. The first gear 5 is fixedly connected to a lifting gear shaft 51. The end of the lifting gear shaft 51 away from the first gear 5 is rotatably connected to the corresponding second lifting end. The lifting gear shaft 51 is fixedly connected to a first support plate 52. The first support plate 52 is located between the first mounting plate 231 and the second mounting plate 232. The first support plate 52 extends in a direction parallel to the ground. The first support plate 52 is used to horizontally lift and rotate the flat steel bars one by one for transport. For each of the turntable assemblies 23, a second gear 6 is sleeved on the drive shaft 22, and the second gear 6 is fixedly mounted on the first base 24; For each of the first power ends, the first power end is equipped with an odd number of power transmission gears 61. If the number of power transmission gears 61 is greater than one, the power transmission gear 61 closer to the first lifting end meshes with the first gear 5, and the power transmission gear 61 farther away from the first lifting end meshes with the second gear 6. If the number of power transmission gears 61 is one, the power transmission gear 61 meshes with the first gear 5 and the second gear 6 respectively.
