Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flat steel stacking, in particular to a rotating disc mechanism and a flat steel automatic stacking system and method using the same. BACKGROUND

[0002] In the field of metallurgy and steel processing, the traditional stacking process of flat steel has long relied on manual operation. Specifically, the operator needs to use a hook to hook each piece of steel on the conveying chain into a collection tank, and then manually transport and stack the steel in the tank to form a stack, and finally complete the stacking and packaging. This operation mode has the following obvious defects: high labor intensity, all actions rely on manual operation, which can easily cause muscle strain or injury to workers; poor stacking quality, low alignment accuracy by manual operation, and misalignment and inclination of flat steel in each layer after stacking, resulting in uneven appearance of the overall stack; low production efficiency, the rhythm of manual hooking and piece arrangement is affected by the physical strength and proficiency of the operator, and cannot match the rhythm of the continuous production line, becoming a bottleneck link that restricts the production capacity of the entire rolling line; low automation, the existing process lacks mechanization and automation, and cannot achieve automatic stacking of flat steel, making it difficult to meet the modern production requirements of high efficiency, safety and intelligence in the rolling workshop.

[0003] In summary, the traditional manual stacking method cannot adapt to the development trend of large-scale, high-strength and continuous production, and there is an urgent need for a flat steel stacking system that can reduce the labor intensity of workers, improve the stacking quality and production efficiency, and achieve automatic operation.

[0005] In a first aspect, the present application provides a flat steel automatic stacking system, which adopts the following technical solution:

[0006] A flat steel automatic stacking system, comprising a first conveying mechanism, a rotating disc mechanism, a stacking mechanism and a second conveying mechanism; the first conveying mechanism is used to convey flat steel produced in a discharge area to the rotating disc mechanism; the rotating disc mechanism is used to transfer flat steel one by one to the stacking mechanism; the stacking mechanism is used to stack flat steel one by one; and the second conveying mechanism is used to transfer the stacked flat steel.

[0007] The rotating disc mechanism comprises a first driving motor, a driving shaft, a plurality of rotating disc assemblies and a first base, the first driving motor is installed on the first base, the output end of the first driving motor transmits power to the driving shaft, each rotating disc assembly comprises a first mounting plate and a second mounting plate, for each rotating disc assembly, the first mounting plate and the second mounting plate are fixedly connected, the driving shaft is fixedly connected with the first mounting plate and the second mounting plate, the first mounting plate comprises a plurality of first lifting ends and a plurality of first power ends, and the second mounting plate comprises a plurality of second lifting ends;

[0008] For each first lifting end, a first gear is installed on the first lifting end, the first gear is fixedly connected with a lifting gear shaft, the end of the lifting gear shaft away from the first gear is rotatably connected with a corresponding second lifting end, the lifting gear shaft is fixedly connected with a first supporting plate, the first supporting plate is located between the first mounting plate and the second mounting plate, the first supporting plate extends in a direction parallel to the ground, and the first supporting plate is used for horizontally lifting and rotating the flat steel one by one to transport the flat steel to the stacking mechanism.

[0009] For each rotating disc assembly, a second gear is arranged on the driving shaft, and the second gear is fixedly installed on the first base.

[0010] For each first power end, an odd number of power transmission gears are installed on the first power end, if the number of the power transmission gears is greater than one, the power transmission gears close to the first lifting end are engaged with the first gear, and the power transmission gears away from the first lifting end are engaged with the second gear, if the number of the power transmission gears is one, the power transmission gears are engaged with the first gear and the second gear respectively.

[0011] By adopting the above technical scheme, the first conveying mechanism, the rotating disc mechanism, the stacking mechanism and the second conveying mechanism can form a mechanized flow line for stacking flat steel, workers are not required to manually carry single flat steel, the labor intensity of workers is reduced, and the risk of injury and collision of hooks during carrying flat steel by workers is reduced. The rotating disc mechanism adopts a structure of revolution and odd-toothed gear chain rotation, so that the first supporting plate can be kept horizontal at any angle, the flat steel can be continuously received and transported horizontally, and the stability of flat steel transportation is improved.

[0012] Optionally, a plurality of transition plates are installed on the first base, upper surfaces of the plurality of transition plates are arranged flush, and the plurality of transition plates are located on a side of the drive shaft away from the first conveying mechanism; for each turntable assembly, a second supporting plate is fixedly connected to an end of the first supporting plate close to the stacking mechanism, and an extension direction of the first supporting plate and an extension direction of the second supporting plate are perpendicular to each other; the first supporting plates corresponding to the current first lifting end transport the flat steels to the plurality of transition plates, and the second supporting plates corresponding to the next first lifting end push the flat steels on the plurality of transition plates to the stacking mechanism.

[0013] By adopting the above technical solution, the transition plate serves as a fixed and flush buffer platform, so that the flat steel can be smoothly placed from the moving first supporting plate to a stable intermediate station, thereby eliminating the impact, sliding or position deviation that may be caused by direct handover, laying a foundation for accurate pushing in the next link. The second supporting plate is connected perpendicularly to the first supporting plate, when the turntable assembly continues to rotate, the second supporting plate will contact the flat steel staying on the transition plate from the side and push it straight into the designated position of the stacking mechanism, thereby converting the rotary power into a straight pushing force, which is smooth and reliable. It is ensured that each flat steel has a consistent and accurate starting position when entering the stacking station, and it is ensured that each flat steel can be neatly stacked, thereby forming a regular steel pile. The whole process is synchronized with the rhythm of the turntable assembly, without stopping, realizing continuous automatic production and improving the overall stacking efficiency.

[0014] Optionally, the stacking mechanism comprises a plurality of first lifting plates and a plurality of first drive assemblies, for each first drive assembly, based on a height of a flat steel pile on the first lifting plate corresponding to the first drive assembly, the height of the first lifting plate relative to the ground is adjusted, so that the plurality of second supporting plates push the flat steels on the plurality of transition plates one by one to the first lifting plates; the stacking mechanism further comprises a plurality of third supporting plates and a plurality of second drive assemblies, for each second drive assembly, based on a width of a flat steel pile on the third supporting plate corresponding to the second drive assembly, the distance between the third supporting plate and the drive shaft is adjusted.

[0015] By adopting the technical scheme, the height of the first lifting plate is adjusted according to the height of the flat steel pile by the first driving assembly, so that consistent and horizontal supporting basis is ensured for each layer of newly pushed flat steel, the uneven problems possibly caused by manual stacking are reduced, and the appearance and quality of the flat steel pile are improved. The second driving assembly can adjust the distance between the third supporting plate and the driving shaft (i.e. the extension position of the third supporting plate), so that flat steel piles of different width specifications can be accommodated and transferred, the versatility of the equipment and the flexibility of the production line are enhanced, and space is also provided for the next flat steel pile. The entire flat steel stacking and transferring process is automatically executed by the driving assemblies, without manual intervention, the labor intensity of workers is reduced, and safety hazards such as pinching and collision that may occur during manual stacking are eliminated.

[0016] Optionally, for each third supporting plate, an end portion away from the driving shaft of the third supporting plate is hinged with a first side baffle, the first side baffle abuts against a side surface of the flat steel pile away from the driving shaft, the first side baffle is connected with a third driving assembly, and the third driving assembly is used to drive the first side baffle to rotate; and the second conveying mechanism comprises a plurality of second lifting plates and a plurality of fourth driving assemblies, and for each fourth driving assembly, the fourth driving assembly is used to adjust the height of the corresponding second lifting plate relative to the ground.

The entire flat steel pile transferring process is automatically completed by the third driving assembly and the fourth driving assembly, without manual intervention, and the labor intensity is greatly reduced.

[0018] Optionally, the stacking mechanism further comprises a plurality of first pushing plates and a plurality of fifth driving assemblies, and for each fifth driving assembly, the fifth driving assembly is used to drive the corresponding first pushing plate to move towards the first side baffle, and when the first pushing plate is in place, the first pushing plate abuts against the side surface of the flat steel pile away from the first side baffle.

[0019] By adopting the technical scheme, the fifth driving assembly pushes the first pushing plate to move towards the flat steel pile until the first pushing plate is in close contact with one side of the pile, and the first side baffle abuts against the other side of the flat steel pile, so that the entire flat steel pile is clamped from both sides. During the flat steel stacking process or after the stacking is completed, the flat steel pile is clamped and arranged, which can effectively correct the slight misalignment of the flat steel, and by applying appropriate lateral pressure to the flat steel pile, the possibility of loosening, tilting or even collapsing of the flat steel pile due to vibration or inertia during movement or transfer can be reduced, and the safety of operation is improved.

[0020] Optionally, the rotating disc mechanism further comprises a second push plate, a first limiting plate and a sixth driving assembly, the second push plate and the first limiting plate are respectively arranged corresponding to the two transition plates at the two ends, when the flat steel is transported to the transition plate, the sixth driving assembly drives the second push plate to move to the side of the transition plate, 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.

[0021] By adopting the above technical scheme, when the flat steel is transported to the transition plate, the sixth driving assembly drives the second push plate to move, so that 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, thereby completing the accurate positioning of the flat steel in the length direction, ensuring that the ends of the flat steel pile finally stacked are neat and uniform in the length direction, greatly improving the quality and appearance of the pile, and providing a consistent and accurate reference position for subsequent stacking.

[0023] By adopting the above technical scheme, the first limiting plate is installed on the support by means of bolts and other fasteners. When different lengths of flat steel need to be processed, the bolts are loosened, the first limiting plate is moved to the mounting hole of the target position corresponding to the length of the current flat steel, and then the bolts are tightened again. The system can adapt to production tasks of flat steel of multiple length specifications, greatly improving the flexibility and flexibility of the production line.

The number of the second limiting plates can be adjusted according to the width of the flat steel, so as to form a width-adjustable guide channel, so that the chain line assembly can convey the flat steel to the rotating disc mechanism one by one.

[0046] 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.

[0047] The present application will be further described in detail below with reference to the accompanying drawings.

[0048] 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.

[0049] like Figures 1 to 3As shown, the carousel mechanism 2 comprises a first driving motor 21, a driving shaft 22, a plurality of carousel assemblies 23, and a first base 24, the first driving motor 21 is mounted on the first base 24, the output end of the first driving motor 21 transmits power to the driving shaft 22, each carousel assembly 23 comprises a first mounting plate 231 and a second mounting plate 232, for each carousel assembly 23, the first mounting plate 231 and the second mounting plate 232 are fixedly connected, the driving shaft 22 is fixedly connected with the first mounting plate 231 and the second mounting plate 232, the first mounting plate 231 comprises a plurality of first lifting ends and a plurality of first power ends, and the second mounting plate 232 comprises a plurality of second lifting ends.

[0050] For each first lifting end, a first gear 5 is mounted on the first lifting end, the first gear 5 is fixedly connected with a lifting gear shaft 51, the end of the lifting gear shaft 51 away from the first gear 5 is rotatably connected with a corresponding second lifting end, the lifting gear shaft 51 is fixedly connected with a first supporting plate 52, the first supporting plate 52 is located between the first mounting plate 231 and the second mounting plate 232, the first supporting plate 52 extends in a direction parallel to the ground, and the first supporting plate 52 is used for lifting and rotating the flat steel one by one in a horizontal direction to transport the flat steel to the stacking mechanism 3.

[0051] For each carousel assembly 23, a second gear 6 is sleeved on the driving shaft 22, and the second gear 6 is fixedly mounted on the first base 24.

[0052] For each first power end, an odd number of power transmission gears 61 are mounted on the first power end, if the number of the power transmission gears 61 is greater than one, the power transmission gears 61 close to the first lifting end are engaged with the first gear 5, and the power transmission gears 61 away from the first lifting end are engaged with the second gear 6, if the number of the power transmission gears 61 is one, the power transmission gear 61 is engaged with the first gear 5 and the second gear 6 respectively.

[0053] In this embodiment, the first conveying mechanism 1 is responsible for conveying the flat steel from the upstream production line (such as a hot-rolled or cold-rolled flat steel production line, a straightening machine, or a shearing machine) to the receiving station of the carousel mechanism 2. The carousel mechanism 2 is one of the core innovations of the system, and its role is to transfer the flat steel received from the first conveying mechanism 1 one by one to the stacking mechanism 3 in a stable and continuous manner. The stacking mechanism 3 is responsible for receiving the flat steel from the carousel mechanism 2 and stacking it into a pile layer by layer. The second conveying mechanism 4 is used to receive the complete flat steel pile transferred from the stacking mechanism 3 and transport it to the next location (such as a bundling station or a warehouse storage area).

[0054] The first base 24 can include a motor mounting seat 241 and a turnover machine base 242, which are fixed to the ground, respectively. The first driving motor 21 can be fixedly installed on the motor mounting seat 241 through a flange or a bolt, and the output end thereof can be connected with the driving shaft 22 through a shaft coupling to provide power for the whole rotating disc mechanism 2, and the first driving motor 21 can be a servo motor. The fixed gear seat 243 is installed on the upper surface of the turnover machine base 242 away from the ground, and the driving shaft 22 can be installed on the fixed gear seat 243 by a bearing seat, and the driving shaft 22 is rotationally connected with the fixed gear seat 243.

[0055] Each rotating disc assembly 23 is fixedly connected by a first mounting plate 231 and a second mounting plate 232 to form a firm frame structure. The driving shaft 22 passes through the center holes of the first mounting plate 231 and the second mounting plate 232 and is fixedly connected therewith through a key groove, so that the rotating disc assembly 23 can rotate together with the driving shaft 22. In the embodiment, the first mounting plate 231 and the second mounting plate 232 can have the same shape, and a gap is provided between the first mounting plate 231 and the second mounting plate 232.

[0056] A plurality of first lifting ends and first power ends are uniformly distributed on the circumference of the first mounting plate 231, and the second mounting plate 232 is provided with second lifting ends at positions corresponding to the first lifting ends of the first mounting plate 231 and is provided with second power ends at positions corresponding to the first power ends of the first mounting plate 231. In the embodiment, four first lifting ends can be provided on the first mounting plate 231, and four second lifting ends can be provided on the second mounting plate 232.

[0057] On each first lifting end, a first gear 5 is installed through 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 rotationally connected with the corresponding second lifting end on the second mounting plate 232 through a bearing. A first supporting plate 52 is fixedly installed on the side wall of the lifting gear shaft 51, the first supporting plate 52 is located in the gap between the first mounting plate 231 and the second mounting plate 232, and the surface of the first supporting 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 driving shaft 22 starts to rotate, each first supporting plate 52 can have a horizontal posture parallel to the ground. When the driving shaft 22 starts to rotate, each first supporting plate 52 can always maintain a horizontal posture parallel to the ground, thereby horizontally lifting the flat steel and transporting the flat steel in a horizontal posture during rotation.

[0058] On each first power end, a plurality of power transmission gears 61 are installed through a shaft and a bearing. Importantly, the number of power transmission gears 61 on each first power end is odd, which ensures correct transmission of motion.

[0059] Each carousel assembly 23 further comprises a second gear 6 sleeved outside the driving shaft 22, the second gear 6 is fixed and not rotating, i.e. not rotating with the driving shaft 22, the second gear 6 can be fixedly installed on the fixed gear seat 243 through a support or directly.

[0060] In this embodiment, the second gear 6 is completely identical to each first gear 5, specifically, the basic meshing parameters, geometric size parameters, material and process parameters of the second gear 6 and each first gear 5 are all the same, the basic meshing parameters can include gear modulus and pressure angle, the geometric size parameters can include gear tooth number and tooth width, and the material and process parameters can include gear material, heat treatment process and manufacturing process. The power transmission gear 61 can also be the same as the first gear 5 and the second gear 6.

[0061] For each carousel assembly 23, on each first power end, when the number of power transmission gears 61 is an odd number greater than 1, the plurality of power transmission gears 61 are sequentially meshed and connected to form a transmission chain, the power transmission gear 61 close to the first lifting end in the transmission chain is meshed with the first gear 5, and the power transmission gear 61 away from the first lifting end is meshed with the fixed second gear 6. When the number of power transmission gears 61 is 1, the power transmission gear 61 is meshed with the first gear 5 and the second gear 6 respectively.

[0062] When the first driving motor 21 starts, the first driving motor 21 drives the driving shaft 22 to rotate, and the driving shaft 22 drives all the carousel assemblies 23 to revolve around the driving shaft 22. Since the power transmission gear 61 at the end of each first power end is meshed with the fixed second gear 6, the revolving motion of the carousel assembly 23 will drive the power transmission gear 61 at the end to rotate around the second gear 6. Due to the gear meshing relationship, the "circulating" of the end gear will drive the entire gear transmission chain to rotate inside the first power end. Because the gear transmission chain is composed of an odd number of power transmission gears 61, when the motion is finally transmitted to the first gear 5, the first gear 5 will generate a self-rotation in the opposite direction of the revolving direction of the driving shaft 22 with the same speed. The self-rotation of the first gear 5 is transmitted to the first supporting plate 52 through the lifting gear shaft 51, so that the first supporting plate 52 can always maintain an absolute horizontal posture while revolving with the carousel assembly 23.

[0063] As shown in Figure 2 and Figure 3 In this embodiment, for each first mounting plate 231, a gear guard 233 is sleeved outside the first lifting end and the first power end corresponding to the first mounting plate 231, and the gear guard 233 is fixedly connected with the first mounting plate 231.

[0064] Through the first conveying mechanism 1, the rotating disc mechanism 2, the stacking mechanism 3 and the second conveying mechanism 4, a mechanized streamline of flat steel stacking can be formed, without the need for workers to manually carry single flat steel, thereby reducing the labor intensity of workers and the risk of injury and collision of hooks during the carrying of flat steel. The rotating disc mechanism 2 adopts a structure of revolution and odd-toothed gear chain rotation, so that the first supporting plate 52 can be kept horizontal at any angle, continuously receive flat steel and complete horizontal transportation of the flat steel, thereby improving the stability of flat steel transportation.

[0065] As shown in Figure 1 and Figure 2 In the embodiment, the driving shaft 22 can include a driving shaft and a plurality of driven shafts. The driving shaft is connected with the first driving motor 21, and the plurality of driven shafts are connected in sequence through couplings to form a driven shaft body. One end of one of the driven shafts in the driven shaft body is connected with the end of the driving shaft away from the first driving motor 21 through a coupling, so as to realize synchronous driving of the plurality of driven shafts by the driving shaft.

[0066] According to the length of the flat steel currently required for stacking, it is calculated how many rotating disc assemblies 23 are required to work. Each rotating disc assembly 23 requires power provided by the driving shaft 22. According to the number, the total length of the driving shaft 22 required can be determined. Then, by increasing or decreasing the number of driven shafts connected by couplings, the driving shaft 22 of the required length can be flexibly assembled.

[0067] For the rotating disc assemblies 23 that do not need to participate in the current flat steel stacking work, the corresponding driven shafts can not be connected with the driving shaft, so that the driven shafts and the rotating disc assemblies 23 in this part will not rotate with the first driving motor 21, thereby avoiding unnecessary idling and significantly reducing energy loss caused by mechanical friction.

[0068] As shown in Figures 1 to 3 In the embodiment, a plurality of transition plates 7 are further installed on the first base 24. The upper surfaces of the plurality of transition plates 7 are arranged in a flush manner, and the plurality of transition plates 7 are located on the side of the driving shaft 22 away from the first conveying mechanism 1. For each rotating disc assembly 23, the end of the first supporting plate 52 close to the stacking mechanism 3 is fixedly connected with a second supporting plate 53. The extension direction of the first supporting plate 52 and the extension direction of the second supporting plate 53 are perpendicular to each other. The first supporting plates 52 corresponding to the current first lifting end transport flat steel to the plurality of transition plates 7, and the second supporting plates 53 corresponding to the next first lifting end push the flat steel on the plurality of transition plates 7 to the stacking mechanism 3.

[0069] The plurality of transition plates 7 and the plurality of rotating disc assemblies 23 are arranged alternately. When a certain first lifting end rotates to the position farthest from the first conveying mechanism 1 (i.e. Figure 3The end face of the first lifting end of the first supporting plate 52 close to the driving shaft 22 can be named as a first end face, and the end face of the first supporting plate 52 away from the driving shaft 22 can be named as a second end face. For each transition plate 7, the end face of the transition plate 7 close to the driving shaft 22 can be named as a third end face, and the end face of the transition plate 7 away from the driving shaft 22 can be named as a fourth end face. The end face of the second supporting plate 53 away from the driving shaft 22 corresponding to the first lifting end can be named as a fifth end face.

[0070] The distance between the first end face and the vertical plane of the axis of the driving shaft 22 is a first distance, the distance between the second end face and the vertical plane of the axis of the driving shaft 22 is a second distance, the distance between the third end face and the vertical plane of the axis of the driving shaft 22 is a third distance, and the distance between the fourth end face and the vertical plane of the axis of the driving shaft 22 is a fourth distance. The first distance is greater than the third distance, and the second distance is less than the fourth distance, so that the flat steel lifted by the first supporting plate 52 can be transferred to the transition plate 7 when the first supporting plate 52 continues to rotate after rotating to the transition plate 7.

[0071] The distance between the fifth end face and the vertical plane of the axis of the driving shaft 22 is a fifth distance, and the fourth distance is less than the fifth distance, so that the second supporting plate 53 corresponding to the next first lifting end can gradually push the flat steel on the transition plate 7 to move away from the driving shaft 22 with the rotation of the first lifting end, so that the flat steel can move from the 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 along the rotation direction of the first mounting plate 231 and the second mounting plate 232.

[0072] As shown in Figures 1 to 3 The height of the upper surface between the end of the transition plate 7 close to the driving shaft 22 and the end away from the driving shaft 22 gradually decreases, so that the upper surface of the transition plate 7 forms an inclined surface. The inclined surface can assist the second supporting plate 53 in pushing the flat steel to the stacking mechanism 3 by using the gravity component of the flat steel itself, so that the flat steel is more labor-saving and stable when being pushed on the transition plate 7 to the stacking mechanism 3. Exemplarily, the upper surface of the transition plate 7 can decrease by 0.5 degrees to 1.5 degrees in the direction away from the driving shaft 22.

[0073] In the embodiment, the first supporting plate 52, the second supporting plate 53 and the transition plate 7 can be plate bodies with good wear resistance, moderate hardness and not easy to deform, so as to protect the surface of the flat steel and maintain the stability of the plate bodies in a long time use. Exemplarily, the first supporting plate 52 and the second supporting plate 53 can be metal materials subjected to surface treatment such as chrome plating or quenching, so that the first supporting plate 52 and the second supporting plate 53 have advantages of high strength, wear resistance, long service life and not easy to deform.

[0074] The flat steel is moved to the stacking mechanism 3 by the first supporting plate 52, the second supporting plate 53 and the transition plate 7 in a way of full sliding and flat pushing, without free falling, which reduces the possibility of surface bumping or side collision of the flat steel.

[0075] As shown in Figure 1 , Figure 3 , Figure 4 and Figure 5 , in the embodiment, the stacking mechanism 3 includes a plurality of first lifting plates 31 and a plurality of first driving assemblies 32, for each first driving assembly 32, the height of the corresponding first lifting plate 31 is adjusted based on the height of the flat steel pile on the first lifting plate 31, so that the plurality of second supporting plates 53 push the flat steel on the plurality of transition plates 7 to the first lifting plate 31 one by one; the stacking mechanism 3 also includes a plurality of third supporting plates 33 and a plurality of second driving assemblies 34, for each second driving assembly 34, the distance between the corresponding third supporting plate 33 and the driving shaft 22 is adjusted based on the width of the flat steel pile on the third supporting plate 33.

[0076] The core function of the stacking mechanism 3 is to receive flat steel and stack it one by one, while performing a series of automatic adjustment operations during stacking and after stacking is completed.

[0077] In the initial lifting state, for each first driving assembly 32, the height of the corresponding first lifting plate 31 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 that there is no flat steel on the first lifting plate 31.

[0078] In the subsequent flat steel transmission state, for each first driving assembly 32, the height of the corresponding first lifting plate 31 is adjusted according to the height of the current flat steel pile, so that the upper surface of the current flat steel pile 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 supporting plate 33. It is easy to understand that the subsequent flat steel transmission state is the state that there is flat steel on the first lifting plate 31.

[0079] If the number of flat steels on the first lifting plate 31 reaches the preset number threshold, the rotating disc mechanism 2 is controlled to pause the transfer of the flat steels, for each first driving assembly 32, the height of the corresponding first lifting plate 31 is adjusted, so that the upper surface of the first lifting plate 31 is lower than the height of the corresponding third supporting plate 33, and the third supporting plate 33 supports the current flat steel stack; for each second driving assembly 34, the distance between the corresponding third supporting plate 33 and the driving shaft 22 is adjusted, so that the width of the upper surface of the third supporting plate 33 near the end of the driving shaft 22 is not less than the width of the flat steel, and based on the corresponding first driving assembly 32, the height of the first lifting plate 31 in the initial lifting state is adjusted.

[0080] The rotating disc mechanism 2 places the flat steels on the plurality of transition plates 7. Then, the second supporting plate 53 of the rotating disc mechanism 2 pushes the flat steels 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 plate 7, so as to facilitate the pushing of the flat steels. The first driving assembly 32 can adopt a servo motor driven screw rod 343 elevator or a hydraulic cylinder for accurately controlling the height of the first lifting plate 31. Whenever a new flat steel is pushed onto the current flat steel stack, the first driving assembly 32 drives the first lifting plate 31 to descend by a distance of the thickness of a flat steel, so as to ensure that the upper surface of the current flat steel stack is always not higher than the upper surface of the transition plate 7, thereby creating conditions for the smooth pushing of the next flat steel.

[0081] The real-time height H of the first lifting plate 31 can be closed-loop controlled by the first driving assembly 32, so as to realize dynamic height tracking between the first lifting plate 31 and the flat steel stack and to descend with the height.

[0082] The real-time height H of the first lifting plate 31 can be expressed as:

[0083] H=H0-Σti-k

[0084] wherein H0 represents the height of the transition plate 7, ti represents the thickness of the i-th flat steel in the current flat steel stack, and k represents a distance constant, for example, k can be 2 mm. The top of the current flat steel stack is ensured to be lower than the transition plate 7, and the next flat steel can be horizontally pushed into the current flat steel stack by the second supporting plate 53, thereby reducing the possibility of collision.

[0085] When the number of the flat steel stacks on the first lifting plate 31 reaches the preset number threshold, the rotating disc mechanism 2 can be controlled to pause the transportation of the flat steel one by one. The first driving assembly 32 drives the first lifting plate 31 to descend until the upper surface thereof is lower than the upper surface of the third supporting plate 33. At this time, the weight of the entire flat steel stack is supported by the third supporting plate 33. The second driving assembly 34 can adopt a linear module or a pneumatic cylinder, and the second driving assembly 34 can drive the third supporting plate 33 to move horizontally. The third supporting plate 33 moves a small distance away from the driving shaft 22, so that a gap not less than the width of a single flat steel is formed between the end thereof and the flat steel stack, so as to prepare for receiving the next flat steel stack. At the same time, the first lifting plate 31 is raised to the initial height, and is ready to start the next stacking cycle.

[0086] When the number of the flat steel stacks reaches the preset number threshold, the first driving assembly 32 drives the first lifting plate 31 to descend by Δh, so that H

[0087] In the embodiment, for each third supporting plate 33, the end thereof away from the driving shaft 22 is hinged with a first side plate 35, the first side plate 35 abuts against the side surface of the flat steel stack away from the driving shaft 22, the first side plate 35 is connected with a third driving assembly 36, and the third driving assembly 36 is used to drive the first side plate 35 to rotate.

[0088] As shown in Figure 1 and Figure 6 The second conveying mechanism 4 includes a plurality of second lifting plates 41 and a plurality of fourth driving assemblies 42, and for each fourth driving assembly 42, the corresponding second lifting plate 41 is adjusted to have a height relative to the ground.

[0089] As shown in Figure 1 , Figure 5 and Figure 6When the flat steel stack on the third pallet 33 reaches the transfer condition, for each second driving assembly 34, adjust the distance between the corresponding third pallet 33 and the driving shaft 22 of the second driving assembly 34 until the flat steel stack is above the corresponding second lifting plate 41, for each fourth driving assembly 42, adjust the height of the corresponding second lifting plate 41 of the fourth driving assembly 42 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 driving assembly 36, drive the corresponding first side plate 35 of the third driving assembly 36 to rotate to the horizontal state, and control the second driving assembly 34 to drive the third pallet 33 to return.

[0090] At the far end of each third pallet 33 (i.e. the end away from the driving shaft 22), a first side plate 35 is hingedly connected by a hinge. In the stacking and storage state, the third driving assembly 36 (such as a small cylinder) keeps it in the vertical state and abuts against the side surface of the flat steel stack, reducing the possibility of the flat steel stack being scattered.

[0091] The second conveying mechanism 4 includes a plurality of second bases 43, and the fourth driving assembly 42 is fixedly installed on the corresponding second base 43. The fourth driving assembly 42 can include a cylinder, and the second lifting plate 41 abuts against the upper surface of the second base 43. The second base 43 also includes a second side plate 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 plate 44, reducing the possibility of the flat steel stack being scattered.

[0092] Each second driving assembly 34 can include a sliding seat 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 sliding seat 341, and the lead screw 343 female seat is threadedly connected with the lead screw 343. The trolley bracket 342 is fixedly connected with the upper surface of the sliding seat 341, and the third pallet 33 can be installed on the upper surface of the trolley bracket 342. The lead screw 343 extends in the direction of the transfer of the flat steel stack from the third pallet 33 to the second lifting plate 41. The stacking mechanism 3 also includes a second driving motor 37 and a plurality of spiral bevel gear reversers 371. The ends of the plurality of lead screws 343 near the second lifting plate 41 are respectively connected with the corresponding spiral bevel gear reversers 371, and the second driving motor 37 synchronously transmits power to the plurality of lead screws 343 through the plurality of spiral bevel gear reversers 371. With the rotation of the lead screw 343, the sliding seat 341 can drive the third pallet 33 to move closer to or away from the second lifting plate 41. In this embodiment, the plurality of lead screws 343 are staggered with the plurality of second bases 43, i.e. the plurality of lead screws 343 can be located between two second bases 43.

[0093] As Figure 5 shown in the embodiment, the stacking mechanism 3 further comprises a plurality of first push plates 38 and a plurality of fifth driving assemblies 381, for each fifth driving assembly 381, a corresponding first push plate 38 is driven to move towards the first side baffle 35, when the first push plate 38 is in place, the first push plate 38 abuts against the side surface of the flat steel pile away from the first side baffle 35.

[0094] The plurality of first push plates 38 are respectively arranged adjacent to the plurality of first side baffles 35, and exemplarily, the plurality of first push plates 38 can be respectively fixedly connected with the trolley brackets 342 of the corresponding first side baffles 35. The first push plate 38 is driven by the fifth driving assembly 381 (such as a pneumatic cylinder) to move towards the plane where the first side baffle 35 is located. During the stacking process of the current flat steel pile or after the stacking is completed, the first push plate 38 can be extended to cooperate with the first side baffle 35 to clamp the flat steel pile from both sides, thereby further ensuring the neatness of the pile shape.

[0095] When the flat steel pile on the third supporting plate 33 reaches the transfer condition, the fifth driving assembly 381 can also drive the first push plate 38 to extend, and keep the first push plate 38 abutting against the side surface of the flat steel pile away from the first side baffle 35, until the flat steel pile is transferred from the third supporting plate 33 to the second lifting plate 41, and then the fifth driving assembly 381 drives the first push plate 38 to reset, thereby improving the stability of the flat steel pile during the transfer to the second lifting plate 41.

[0096] As Figure 1 , Figure 4 and Figure 7 shown in the embodiment, the rotating disc mechanism 2 further comprises a second push plate 25, a first limiting plate 26 and a sixth driving assembly 27, the second push plate 25 and the first limiting plate 26 are respectively arranged corresponding to the two transition plates 7 at the head and tail ends, when the flat steel is transported to the transition plate 7, the sixth driving assembly 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.

[0097] The second push plate 25 can be located outside the head transition plate 7 (close to the side of the first driving motor 21), and is horizontally driven by the sixth driving assembly 27 (such as a pneumatic cylinder or a servo cylinder), and the movement direction is parallel to the length direction of the flat steel. The first limiting plate 26 is located outside the tail transition plate 7 (away from the side of the first driving motor 21).

[0098] The pushing process of the second push plate 25 on the flat steel can be represented as:

[0099] When the flat steel is unloaded from the first supporting plate 52 to the transition plate 7, a "in-place" signal can be given by a laser sensor;

[0100] The sixth driving assembly 27 is immediately pushed out, and the second push plate 25 can push the flat steel to translate to the tail end at a speed of 50 mm / s;

[0101] The rear end surface of the flat steel is in contact with the first limiting plate 26, and after the pressure relay in the first limiting plate 26 detects 0.3 MPa, the sixth driving assembly 27 can be kept for 0.5 s, and the abutting of the flat steel and the first limiting plate 26 is completed.

[0102] A control signal allowing rotation is sent to the turntable mechanism 2, the turntable mechanism 2 continues to rotate, the second supporting plate 53 enters the pushing phase, and the sixth driving assembly 27 retreats to the original position and waits for the next flat steel.

[0103] The flat steel in transit may slide due to inertia, and the incoming flat steel may not be in consistent position. In order to improve the neatness of the flat steel stack, each flat steel can be given “forced zero” by the second push plate 25, so that the tail reference of each flat steel is uniform, and after stacking, the both ends are flush to meet the preset flushness requirement, which can save the workload of manual secondary edge alignment.

[0104] In the embodiment, the first lifting plate 31, the third supporting plate 33, the first side plate 35, the first lifting plate 31, the first push plate 38 and the second push plate 25 can also be plate bodies with good wear resistance, moderate hardness and not easy to deform, for example, metal materials subjected to surface treatment such as chrome plating or quenching.

[0105] In the embodiment, the turntable mechanism 2 further includes a plurality of supports 28, each of the supports 28 includes a plurality of mounting holes 281, and the plurality of supports 28 and the plurality of mounting holes 281 are respectively distributed along the length direction of the flat steel. The first limiting plate 26 is fixedly connected with the mounting hole 281 corresponding to the target position, and the target position corresponds to the length of the flat steel currently subjected to stacking treatment.

[0106] One support 28 is arranged at a fixed distance along the length direction of the flat steel, and a plurality of supports 28 can be arranged between the first and second transition plates 7, which can cover the full length of 3-12 m of the flat steel. Each support 28 is provided with a plurality of mounting holes 281, and the transverse hole distance can be 50 mm, and the mounting holes form an equidistant hole matrix. In the embodiment, the two side surfaces of the bottom of the first limiting plate 26 each have two mounting points arranged in upper and lower positions, so that the first limiting plate 26 can be fixed by selecting four mounting holes 281 corresponding to the length of the flat steel.

[0107] For example, Figure 1 , Figure 2 and Figure 8As 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] In this embodiment, when the first pallet 52 rotates to the position furthest from the palletizing mechanism 3 (i.e. Figure 3 The 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.

[0112] 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.
