Description

Technical Field

[0001] This application relates to the technical field of metal processing equipment, and particularly to a sheet flying shear and receiving device. Background Art

[0002] Before processing metal coils into products, it is generally necessary to cut the metal coils into strips. The current system for completing the above cutting process includes an uncoiler, a leveling machine, a film laminating machine, a flying shear, and a stacking machine arranged side by side in sequence. In this way, during the metal coil processing process, the metal coils are sequentially uncoiled, leveled, film laminated, and then stacked together after flying shear.

[0003] In the prior art, when stacking, the conveyor belt transports the cut steel plates to two rows of rollers arranged oppositely on the stacking machine, and the two rows of rollers respectively support the bottom surfaces on both sides of the steel plates. When the steel plate slides on the rollers to a predetermined position, the two rows of rollers respectively swing outward towards the outer sides of the two sides of the steel plate, so that the steel plate falls freely after being separated from the support of the rollers to complete stacking. However, when the steel plate is transported from the conveyor belt to the rollers, due to the action of inertia, the steel plate will continue to slide forward after reaching the rollers until it hits the front limiting structure and then stops, and the impact easily causes the steel plate to deform and bend. Moreover, when the rollers support a thin steel plate with a large width, the steel plate will be affected by its own weight and cause the middle part to sink downward, which not only further increases the risk of steel plate deformation, but also may cause the unexpected situation that the steel plate slides off the rollers, affecting the continuity of production and the product quality. Summary of the Invention

[0004] In order to reduce the deformation of the steel plates during stacking and improve the continuity and yield rate of steel plate production, this application provides a sheet flying shear and receiving device.

[0005] The sheet flying shear and receiving device provided by this application adopts the following technical solutions: A sheet flying shear and receiving device includes: A frame; A stacking assembly, the stacking assembly includes at least two swing rods, a plurality of rollers, and a first driving member; the two swing rods are rotatably arranged on the frame, and the extending directions and rotation axes of the two swing rods are both parallel to the conveying direction of the steel plate; the plurality of rollers are divided into two groups and are respectively rotatably arranged on the two swing rods along the extending direction of the swing rods, and the plurality of rollers are used for rolling against and supporting the steel plate; the first driving member is used to drive the swing rods to swing reciprocally so that the two swing rods approach or move away from each other; A conveying assembly, comprising at least two conveying rollers, a second driving member, and a first detector; the two conveying rollers are rotatably mounted on a frame and are respectively configured to roll and abut against the upper and lower surfaces of a steel plate; the second driving member is configured to drive the two conveying rollers to rotate so as to convey the steel plate onto the rollers; the first detector is configured to detect the distance between the front and rear ends of the steel plate and the conveying rollers, and the first detector is electrically connected to the second driving member to control the speed at which the second driving member drives the conveying rollers to rotate; a pneumatic assembly, the pneumatic assembly being used to blow air toward the bottom surface of the steel plate to support the steel plate; The material receiving assembly includes a material receiving platform, which is arranged below the stacking assembly and is used for receiving and stacking steel plates.

[0006] By adopting the above-mentioned technical solution, the deformation of steel plates when stacked can be effectively reduced, and the continuity and yield of steel plate production can be improved. Specifically, after the cut steel plates are transported to the conveying assembly by the external conveyor belt, the second drive member drives the conveyor roller to rotate, and smoothly transfers the steel plates from the conveyor belt at the same conveying speed as the external conveyor belt, and then transports them to the roller. During this process, the first detector detects the distance between the two ends of the steel plate and the conveyor roller in real time, and controls the second drive member to adjust the speed of the conveyor roller based on the detection results. When it is detected that the end of the steel plate is about to leave the conveyor roller, the first detector will control the speed of the conveyor roller to decrease, thereby greatly reducing the inertia of the steel plate after it is transported to the roller, so that the steel plate can stop quickly, avoiding the impact deformation problem caused by using a limit structure to stop the steel plate in the traditional way, and significantly improving the production quality and production continuity of the steel plate. At the same time, the pneumatic component continuously blows air to the bottom surface of the steel plate, providing upward support force when the steel plate is conveyed to the roller, effectively offsetting the concave phenomenon in the middle part of the steel plate caused by its own weight, further reducing the risk of steel plate deformation, and ensuring the flatness of the steel plate during the conveying and stacking process, thereby comprehensively improving the steel plate's yield and production efficiency.

[0007] Optionally, the material holding assembly also includes a lifting platform and a second detector; the lifting platform is used to install the material holding table and drive the material holding table to lift and lower; the second detector is electrically connected to the lifting platform and is used to detect the height of the steel plates stacked on the material holding table in real time, and the second detector can control the descent of the lifting platform based on the detected numerical value such as the height of the steel plates stacked on the material holding table.

[0008] By adopting this technical solution, the lifting platform can automatically adjust the position of the loading platform according to the height of the steel plate stack, ensuring that the steel plates always descend smoothly during the stacking process. This prevents the steel plates from sliding due to stacking too high or tilting due to large height differences in the steel plates falling, thereby improving the stability and safety of the stacking. In addition, this design can also adapt to the stacking needs of steel plates of different thicknesses and quantities, improving the versatility and automation level of the equipment.

[0009] Optionally, it also includes an adjustment component, which includes a first slide rail and a first self-driven slide and a second self-driven slide slidably arranged on the first slide rail; the first slide rail is arranged on the frame, and the extension direction of the first slide rail is parallel to the horizontal plane and perpendicular to the conveying direction of the steel plate; the first self-driven slide and the second self-driven slide can both slide on the first slide rail by self-drive; the two rocker arms are respectively rotatably arranged on the first self-driven slide and the second self-driven slide.

[0010] By adopting the above-mentioned technical solution, the configuration of the adjustment assembly enables the swing arm to be adjusted according to actual production needs. Specifically, the first slide rail provides guidance for the first and second self-propelled slides, allowing them to slide horizontally and perpendicular to the direction of steel plate conveyance, thereby enabling flexible adjustment of the distance between the two swing arms. This design not only adapts to the stacking requirements of steel plates of varying widths, but also optimizes the distribution of the steel plates on the swing arms to a certain extent, reducing the risk of overhanging edges or unstable support caused by a mismatch between steel plate width and swing arm spacing. This, in turn, reduces the risk of steel plate deformation and improves the device's applicability and stacking stability.

[0011] Optionally, a limiting assembly is also included, which includes a first limiting plate, a first push plate and a third driving member; the first limiting plate is arranged on the first self-driving slide for abutting against the side of the stacked steel plates parallel to its own conveying direction; the first push plate is slidably arranged on the second self-driving slide, and the first push plate is located on the side of the stacked steel plates away from the first limiting plate; the third driving member is used to drive the first push plate close to or away from the first limiting plate.

[0012] By adopting the above technical solution, the first limit plate and the first push plate can limit the steel plates stacked on the material platform on both sides of their conveying direction, effectively preventing the steel plates from shifting or tilting during the stacking process. Specifically, before the steel plate falls onto the material platform, the third drive member drives the first push plate away from the first limit plate, providing a certain displacement margin for the steel plate when it falls, so as to ensure that the steel plate can stably fall on the material platform or the stacked steel plates; after the steel plate falls onto the material platform or the stacked steel plates, the third drive member drives the first push plate close to the first limit plate, so as to press the side of the steel plate parallel to its own conveying direction against the first limit plate, thereby eliminating the relative offset between the steel plates and significantly improving the neatness and quality of the stacked steel plates. At the same time, since the position of the first self-driven slide and the second self-driven slide is adjustable, the distance between the first push plate and the first limit plate can be flexibly adjusted according to actual needs, thereby adapting to steel plates of different sizes and specifications, ensuring that all types of steel plates can achieve efficient and stable stacking effects.

[0013] Optionally, the limiting component further includes a second slide rail, a third self-driven slide seat, a second limiting plate, and a second pushing plate; the second slide rail is arranged on the rack, and the extending direction of the second slide rail is parallel to the horizontal plane and the conveying direction of the steel plate; the third self-driven slide seat is slidably arranged on the second slide rail, and the third self-driven slide seat can slide on the second slide rail through self-driving; the second limiting plate is arranged on the rack and is used for abutting against one side of the stacked steel plates close to the conveying roller; the second pushing plate is arranged on the third self-driven slide seat and is used for abutting against the side of the steel plate far from the conveying roller.

[0014] By adopting the above technical solution, the second limiting plate and the second pushing plate can limit the stacked steel plates on both sides perpendicular to their conveying direction, effectively preventing the steel plates from shifting or tilting during the stacking process. Specifically, before the steel plate falls onto the material receiving table, the third self-driven slide seat drives the second pushing plate away from the second limiting plate to provide a certain displacement margin when the steel plate falls, so as to ensure that the steel plate can stably fall onto the material receiving table or the stacked steel plates; after the steel plate falls onto the material receiving table or the stacked steel plates, the third self-driven slide seat drives the second pushing plate close to the second limiting plate to abut one side surface of the steel plate close to the conveying roller against the second limiting plate, thereby eliminating the relative offset between the steel plates and significantly improving the neatness and quality of the stacked steel plates. At the same time, since the position of the third self-driven slide seat is adjustable, the distance between the second pushing plate and the second limiting plate can be flexibly adjusted according to actual needs, so as to adapt to steel plates of different sizes and specifications and ensure that various types of steel plates can achieve efficient and stable stacking effects.

[0015] Optionally, an elastic member is arranged between the second pushing plate and the third self-driven slide seat. One end of the elastic member is connected to the second pushing plate, and the other end is connected to the third self-driven slide seat. The elastic member is used to make the second pushing plate bounce towards the direction close to the steel plate.

[0016] By adopting the above technical solution, the elastic member can provide buffering when the second pushing plate abuts against the steel plate, effectively avoiding damage or deformation of the surface of the steel plate caused by the hard contact between the second pushing plate and the steel plate. At the same time, in special cases where the steel plate fails to stop in time due to inertia and continues to slide, the elastic member can provide additional buffering space and a stopping effect for the steel plate through its elastic characteristics, thereby preventing the steel plate from hitting and deforming the second pushing plate due to excessive sliding and ensuring the flatness and integrity of the steel plate during the stacking process.

[0017] Optionally, the pneumatic component includes a ventilation seat and a blower. The ventilation seat is arranged on the rack. A ventilation cavity is opened in the ventilation seat. The air outlet of the blower is communicated with the ventilation cavity. A first exhaust hole communicated with the ventilation cavity is opened on the ventilation seat. The blower can blow air towards the bottom surface of the steel plate through the first exhaust hole.

[0018] By adopting the above technical solution, the fan blows air into the ventilation cavity, and after the gas is discharged from the first exhaust hole, a uniform air flow layer is formed on the bottom surface of the steel plate. This air flow layer can generate a stable supporting force under the steel plate, reduce the phenomenon that the middle part of the steel plate sags downward due to its own weight, and thus reduce the risk of steel plate deformation. At the same time, the formation of the air flow layer can also reduce the impact of the steel plate when it falls on the material receiving table or the stacked steel plates, further improving the stability of steel plate stacking.

[0019] Optionally, an exhaust passage penetrating through both ends of the swing rod is provided in the swing rod, and a communication hole communicating with the ventilation cavity is provided on one surface of the ventilation base close to the swing rod; one end of the swing rod is in sliding contact with the ventilation base to communicate the exhaust passage with the communication hole; a fan blade is provided at one end of the roller located in the exhaust passage; when the fan blows air into the exhaust passage through the communication hole, the fan blade can drive the roller to rotate, and the rotation direction of the roller is opposite to the rotation direction of the conveying roller on one side of the bottom surface of the steel plate.

[0020] By adopting the above technical solution, when the fan blows air into the exhaust passage, the air flow drives the fan blade to rotate, and then drives the roller to rotate. Since the rotation direction of the roller is opposite to the rotation direction of the conveying roller on one side of the bottom surface of the steel plate, when the steel plate is conveyed onto the roller and contacts the roller, the roller can drive the steel plate to move in a direction opposite to the steel plate conveying direction. This reverse movement can effectively reduce the forward sliding tendency of the steel plate due to inertia, thus avoiding deformation or bending of the steel plate caused by hitting the front object during the stacking process, and improving the stability of steel plate stacking and production quality.

[0021] Optionally, a U-shaped plate is provided on the ventilation base. The U-shaped plate is located above the roller and is used to cover the steel plate on the roller. The U-shaped groove of the U-shaped plate faces the steel plate side, and the extending direction of the U-shaped groove is parallel to the conveying direction of the steel plate; an adsorption cavity is formed between the U-shaped plate and the steel plate on the roller, and a second exhaust hole communicating with the adsorption cavity is provided on one surface of the ventilation base close to the swing rod; when the conveying roller conveys the steel plate onto the roller, the gas in the ventilation cavity enters from one end of the adsorption cavity close to the ventilation base through the second exhaust hole and is discharged from the other end of the adsorption cavity far from the ventilation base.

[0022] By adopting the above technical solution, when the steel plate is conveyed onto the roller, an adsorption cavity is formed between the U-shaped plate and the steel plate on the roller. The gas in the ventilation cavity enters the adsorption cavity through the second exhaust hole and is discharged from the end of the adsorption cavity far away from the ventilation seat. During this process, according to Bernoulli's principle, the high-speed flowing air causes the pressure at the end of the adsorption cavity close to the ventilation seat to decrease, while the atmospheric pressure outside the adsorption cavity is relatively high, thus forming a pressure difference between the steel plate and the U-shaped plate. This pressure difference prompts the steel plate to approach the U-shaped plate, effectively offsetting the bending deformation of the steel plate caused by its own weight and ensuring the flatness of the steel plate. At the same time, the flowing air can also carry away the dust on the upper surface of the steel plate, further improving the quality and stacking effect of the steel plate.

[0023] Optionally, a switch plate is slidably arranged on the ventilation seat. The switch plate is in sealed sliding contact with the surface of the ventilation seat close to the swing rod. A rack is arranged on the switch plate, and a gear meshing with the rack is arranged on the swing rod. When the swing rod swings, it can drive the switch plate to slide up and down through the gear and the rack; a pressure relief valve is arranged in the second exhaust hole; when the two swing rods approach each other, the switch plate can cover the first exhaust hole and open the second exhaust hole and the communication hole; when the two swing rods move away from each other, the switch plate can cover the second exhaust hole and the communication hole and open the first exhaust hole.

[0024] By adopting the above technical solution, when the steel plate has not been conveyed onto the roller, the two swing rods approach each other. Under the driving action of the gear and the rack, the switch plate covers the first exhaust hole and opens the second exhaust hole and the communication hole. At this time, the gas in the ventilation cavity is guided into the exhaust passage and the second exhaust hole. However, since the air pressure has not reached the opening threshold of the pressure relief valve, the gas is only discharged from the exhaust passage, blowing the fan blades to rotate, thereby driving the roller to rotate. This design provides a necessary pre-deceleration function for the subsequent contact between the steel plate and the roller, ensuring a smooth transition of the steel plate to the supporting state. When the steel plate is conveyed onto the roller, the roller comes into contact with the steel plate and gradually decelerates until it stops rotating. At this time, the fan blades on the roller automatically block the exhaust passage, resulting in an increase in the air pressure in the ventilation cavity and exceeding the set threshold of the pressure relief valve. The gas then flows into the adsorption cavity through the pressure relief valve to generate an adsorption force to offset the bending deformation of the steel plate caused by its own weight. Finally, after the steel plate is positioned, the two swing rods move away from each other to release the steel plate for free-fall stacking operation. During the swinging process of the swing rod, the switch plate moves accordingly, closing the second exhaust hole and the communication hole and opening the first exhaust hole. At this time, the gas in the ventilation cavity is only discharged from the first exhaust hole, forming a stable air flow layer below the steel plate to provide support for the steel plate during the falling process, effectively reducing the impact force of the steel plate on the material receiving table when it falls. The whole process realizes the dynamic switching of the gas flow direction, not only ensuring that the steel plate obtains appropriate gas support and guidance in different operation stages, but also effectively reducing the unnecessary loss of the air flow and minimizing the energy waste to the greatest extent, significantly improving the operation efficiency and automation degree of the device.

[0025] In summary, the present application includes the following beneficial technical effects: 1. It can effectively reduce the deformation of steel plates during stacking, and improve the continuity and yield of steel plate production. Specifically, after the cut steel plates are conveyed to the conveying component by the external conveyor belt, the second driving member drives the conveying rollers to rotate, and transfers the steel plates from the conveyor belt smoothly at the same conveying speed as the external conveyor belt, and then conveys them onto the rollers. During this process, the first detector continuously detects the distances between the head and tail ends of the steel plates and the conveying rollers, and controls the second driving member to adjust the rotation speed of the conveying rollers according to the detection results. When it is detected that the end of the steel plate is about to break away from the conveying rollers, the first detector will control the rotation speed of the conveying rollers to decrease, thereby greatly reducing the inertia of the steel plates after being conveyed onto the rollers, enabling the steel plates to stop quickly, avoiding the impact deformation problem caused by using a limiting structure to stop the steel plates in the traditional method, and significantly improving the production quality and continuity of the steel plates. At the same time, the pneumatic component continuously blows air towards the bottom surface of the steel plates, providing an upward supporting force when the steel plates are conveyed onto the rollers, effectively offsetting the phenomenon of the middle part of the steel plates sagging due to their own weight, further reducing the risk of steel plate deformation, ensuring the flatness of the steel plates during conveying and stacking, and thus comprehensively improving the yield and production efficiency of the steel plates; 2. When the steel plates are conveyed onto the rollers, an adsorption cavity is formed between the U-shaped plates and the steel plates on the rollers. The gas in the ventilation cavity enters the adsorption cavity through the second exhaust holes and is discharged from the end of the adsorption cavity far from the ventilation seat. During this process, according to Bernoulli's principle, the high-speed flowing air causes the pressure at the end of the adsorption cavity close to the ventilation seat to decrease, while the atmospheric pressure outside the adsorption cavity is relatively high, thereby forming a pressure difference between the steel plates and the U-shaped plates. This pressure difference prompts the steel plates to approach the U-shaped plates, effectively offsetting the bending deformation of the steel plates due to their own weight and ensuring the flatness of the steel plates. At the same time, the flowing air can also carry away the dust on the upper surface of the steel plates, further improving the quality and stacking effect of the steel plates; 3. When the steel plate has not been conveyed onto the rollers, the two swing rods approach each other. Under the driving action of the gear and the rack, the switch plate covers the first exhaust hole and opens the second exhaust hole and the communication hole. At this time, the gas in the ventilation cavity is guided into the exhaust passage and the second exhaust hole. However, since the air pressure has not reached the opening threshold of the pressure relief valve, the gas is only discharged from the exhaust passage, blowing the fan blades to rotate, thereby driving the rollers to rotate. This design provides a necessary pre-deceleration function when the steel plate comes into contact with the rollers later, ensuring a smooth transition of the steel plate to the supported state. When the steel plate is conveyed onto the rollers, the rollers come into contact with the steel plate and gradually decelerate until they stop rotating. At this time, the fan blades on the rollers automatically block the exhaust passage, causing the air pressure in the ventilation cavity to rise and exceed the set threshold of the pressure relief valve. The gas then flows into the adsorption cavity through the pressure relief valve to generate an adsorption force to counteract the bending deformation of the steel plate due to its own weight. Finally, after the steel plate is positioned, the two swing rods move away from each other to release the steel plate for free-fall stacking operation. During the swinging process of the swing rods, the switch plate moves accordingly, closing the second exhaust hole and the communication hole and opening the first exhaust hole. At this time, the gas in the ventilation cavity is only discharged from the first exhaust hole, forming a stable air flow layer below the steel plate to provide support for the steel plate during the falling process, effectively reducing the impact force of the steel plate on the receiving table when it falls. The entire process realizes the dynamic switching of the gas flow direction, not only ensuring that the steel plate obtains appropriate gas support and guidance at different operation stages, but also effectively reducing the unnecessary loss of the air flow and minimizing the energy waste to the greatest extent, significantly improving the operation efficiency and automation degree of the device.

Detailed implementation manners

[0034] The following is a further detailed description of the present application in conjunction with Figures 1-7 This application is further described in detail below.

[0035] The embodiment of the present application discloses a flying shear material receiving device for plates.

[0036] Embodiment 1 Referring to Figure 1 and Figure 2 , the material receiving device includes a frame 1, a stacking component 2, a conveying component 3, a pneumatic component 4, a material receiving component 5, an adjusting component 6, and a limiting component 7. Specifically, the frame 1 is a metal frame made of high-strength square steel welded together, which provides support for other components.

[0037] The stacking assembly 2 includes two rocker arms 21, a plurality of rollers 22 and a first driving member 23. The rocker arm 21 is specifically a rectangular steel tube. The two rocker arms 21 are respectively rotatably arranged on the frame 1 through a connecting rod fixed to the outer wall thereof. The extension direction and the rotation axis of the two rocker arms 21 are parallel to the conveying direction and the horizontal plane of the steel plate; the roller 22 is specifically a rubber roller with a fixed rotating shaft. The plurality of rollers 22 are divided into two groups. The number of rollers 22 in each group can be flexibly adjusted according to actual needs. For example, each group can contain 15 or 20 rollers 22; the two groups of rollers 22 are arranged opposite to each other, and the two groups of rollers 22 are arranged along the extension direction of the rocker arm 21. The first drive member 23 can be a pneumatic cylinder or a hydraulic cylinder. There are two first drive members 23. The two first drive members 23 are respectively used to drive the two rockers 21 to swing back and forth so that the two rockers 21 are close to or away from each other. A position sensor for detecting the position of the steel plate on the roller 22 is provided on the frame 1. The first drive member 23 is electrically connected to the position sensor. When the position sensor detects that the steel plate is completely placed on the roller 22, the first drive member 23 drives the rocker 21 to swing and then reset, so that the steel plate can fall freely after being separated from the support of the roller 22, thereby realizing orderly stacking of the steel plates.

[0038] Reference Figure 1 and Figure 2 In this embodiment, the conveying assembly 3 is arranged on the frame 1 and is located at one end of the upper steel plate input of the rocker arm 21; the conveying assembly 3 includes two conveying rollers 31, a second driving member 32 and a first detector 33; the two conveying rollers 31 are arranged opposite to each other and are rotatably mounted on the frame 1 through bearings, and the rotation axes of the two conveying rollers 31 are parallel to the horizontal plane and perpendicular to the conveying direction of the steel plate, and the two conveying rollers 31 roll against the upper and lower surfaces of the steel plate respectively; the second driving member 32 is a servo motor, which is mounted on the frame 1 and is connected to the two conveying rollers 31 through gears to drive the conveying rollers 31 to rotate and convey the steel plate and can accurately control the rotation speed of the conveying rollers 31; the first detector 33 is a photoelectric sensor, which is mounted on the side of the conveying roller 31 away from the rocker arm 21 and is electrically connected to the second driving member 32. The first detector 33 can detect the distance between the head and tail ends of the steel plate and the conveying roller 31 in real time, and transmit the detection signal to the second driving member 32 to realize dynamic adjustment of the rotation speed of the conveying roller 31.

[0039] In this way, the second drive member 32 drives the conveyor roller 31 to rotate, smoothly transferring the steel plate from the outer conveyor belt at the same conveying speed as the outer conveyor belt, and then conveying it to the roller 22. When the first detector 33 detects that the end of the steel plate is about to leave the conveyor roller 31, it controls the conveyor roller 31 to reduce its rotation speed, thereby significantly reducing the inertia of the steel plate after being conveyed to the roller 22, allowing the steel plate to stop quickly. When the first detector 33 detects that the next steel plate is about to reach the conveyor roller 31, it controls the conveyor roller 31 to resume its rotation speed. It is important to emphasize that the spacing between steel plates must ensure that the previous steel plate has completely left the conveyor roller 31 before the next steel plate reaches the conveyor roller 31.

[0040] Reference Figure 1 and Figure 2 In this embodiment, the pneumatic component 4 includes a ventilation seat 41 and a fan 42; the ventilation seat 41 is fixed on the frame 1 and is located below the side of the conveying roller 31 close to the rocker arm 21, and a closed ventilation cavity 411 is provided inside the ventilation seat 41; the air outlet of the fan 42 is connected to the ventilation cavity 411 through a pipe, and a first exhaust hole 412 connected to the ventilation cavity 411 is provided on the ventilation seat 41; the fan 42 can blow air toward the bottom surface of the steel plate through the first exhaust hole 412, thereby forming a uniform air flow layer on the bottom surface of the steel plate on the conveying roller 31, so as to provide upward support force for the steel plate and offset the concave middle part of the steel plate caused by its own weight.

[0041] Reference Figure 1 and Figure 2 In this embodiment, the material receiving assembly 5 includes a material receiving platform 51, a lifting platform 52 and a second detector 53; the material receiving platform 51 and the lifting platform 52 are both arranged below the stacking assembly 2, and the material receiving platform 51 is fixed on the lifting platform 52; the material receiving platform 51 is used to receive and stack steel plates; the lifting platform 52 is fixed to control the rise or fall of the material receiving platform 51, and the second detector 53 is a grating sensor, which is arranged on the material receiving platform 51 to detect the height of the steel plates stacked on the material receiving platform 51; the second detector 53 is electrically connected to the lifting platform 52, and the second detector 53 can control the lifting platform 52 to descend according to the detected numerical value such as the height of the steel plates stacked on the material receiving platform 51. In this way, the lifting platform 52 can automatically adjust the position of the material receiving platform 51 according to the height of the steel plates stacked, ensuring that each steel plate always maintains the same falling height during the stacking process, avoiding the problem of steel plates sliding due to stacking too high or steel plates tilting due to too large a height difference of falling steel plates.

[0042] Reference Figure 1 and Figure 2, in this embodiment, the adjusting component 6 includes a first slide rail 61, a first self-driven slide block 62 and a second self-driven slide block 63; the first slide rail 61 is specifically composed of two smooth guide rods and a lead screw, the first slide rail 61 is fixed on the frame 1, and the extending direction of the first slide rail 61 is parallel to the horizontal plane and perpendicular to the conveying direction of the steel plate; the first self-driven slide block 62 and the second self-driven slide block 63 are slidably arranged on the first slide rail 61, and power components are installed inside the first self-driven slide block 62 and the second self-driven slide block 63 to drive themselves to slide on the first slide rail 61; the two swing rods 21 are respectively rotatably connected to the first self-driven slide block 62 and the second self-driven slide block 63 through connecting rods fixed on their outer walls. In this way, by adjusting the distance between the first self-driven slide block 62 and the second self-driven slide block 63 on the first slide rail 61, the distance between the two swing rods 21 can be adjusted according to actual production requirements to adapt to the stacking requirements of steel plates of different widths.

[0043] Referring to Figure 1 and Figure 2 , in this embodiment, the limiting component 7 includes a first limiting plate 71, a first pushing plate 72, a third driving member 73, a second slide rail 74, a third self-driven slide block 75, a second limiting plate 76 and a second pushing plate 77; the first limiting plate 71 is specifically a long strip-shaped metal plate with a length close to that of the swing rod 21, the first limiting plate 71 is fixed on the first self-driven slide block 62, the first limiting plate 71 is parallel to the conveying direction of the steel plate and is used to abut against one side of the steel plates stacked on the material receiving table 51 parallel to its own conveying direction; the first pushing plate 72 is also a long strip-shaped metal plate with a length close to that of the swing rod 21, the first pushing plate 72 is arranged parallel to the first limiting plate 71 face to face, the first pushing plate 72 is slidably connected to the first self-driven slide block 62, and the sliding direction of the first pushing plate 72 is parallel to the horizontal plane and perpendicular to the conveying direction of the steel plate; the third driving member 73 can be a cylinder or a hydraulic cylinder, the third driving member 73 is fixed on the second self-driven slide block 63, and the output end of the third driving member 73 is connected to the first pushing plate 72 to drive the first pushing plate 72 to approach or move away from the first limiting plate 71.

[0044] Referring to Figure 1 and Figure 2, in this embodiment, the second slide rail 74 is specifically composed of two smooth guide rods and a lead screw. The second slide rail 74 is fixed on the frame 1, and the extending direction of the second slide rail 74 is parallel to the horizontal plane and the conveying direction of the steel plate; the third self-driven slide 75 is slidably arranged on the second slide rail 74, and a power component is installed inside the third self-driven slide 75 to drive itself to slide on the second slide rail 74; the second limiting plate 76 is specifically a long strip-shaped metal plate with a length close to that of the conveying roller 31. The second limiting plate 76 is fixed on the frame 1 and is used to abut against the side of the steel plate stacked on the material receiving table 51 close to the conveying roller 31; the second pushing plate 77 is specifically a rectangular metal plate, and the second pushing plate 77 is arranged on the third self-driven slide 75 and is used to abut against the side of the steel plate away from the conveying roller 31; an elastic member 78 is arranged between the second pushing plate 77 and the third self-driven slide 75. The elastic member 78 is a spring. One end of the elastic member 78 is fixed on the second pushing plate 77, and the other end is fixed on the third self-driven slide 75. The elastic member 78 is used to make the second pushing plate 77 bounce towards the steel plate.

[0045] In this way, before the steel plate falls onto the material receiving table 51, the third driving member 73 drives the first pushing plate 72 away from the first limiting plate 71 to provide a certain longitudinal displacement margin when the steel plate falls; the third self-driven slide 75 drives the second pushing plate 77 away from the second limiting plate 76 to provide a certain lateral displacement margin when the steel plate falls; thereby ensuring that the steel plate can stably fall onto the material receiving table 51 or the stacked steel plates. After the steel plate falls onto the material receiving table 51 or the stacked steel plates, the third driving member 73 drives the first pushing plate 72 to approach the first limiting plate 71 to abut one side surface of the steel plate parallel to its own conveying direction against the first limiting plate 71; the third self-driven slide 75 drives the second pushing plate 77 to approach the second limiting plate 76 to abut the side surface of the steel plate close to the conveying roller 31 against the second limiting plate 76, so as to eliminate the relative offset between the steel plates and improve the neatness of the stacked steel plates. Moreover, by adjusting the distance between the first self-driven slide 62 and the second self-driven slide 63, the distance between the first pushing plate 72 and the first limiting plate 71 can be adjusted; by adjusting the position of the third self-driven slide 75 on the second slide rail 74, the distance between the second pushing plate 77 and the second limiting plate 76 can be adjusted, so as to meet the stacking requirements of steel plates of different sizes and specifications. In addition, the elastic member 78 can provide buffering when the second pushing plate 77 abuts against the steel plate, avoiding damage or deformation of the steel plate caused by the hard contact between the second pushing plate 77 and the steel plate; and when the steel plate fails to stop in time due to inertia and continues to slide, the elastic member 78 can provide buffering and blocking effects for the steel plate.

[0046] The implementation principle of Example 1 is as follows: when the cut steel plates need to be stacked, the second driving member 32 drives the conveyor roller 31 to rotate, and smoothly transfers the steel plates from the external conveyor belt at the same conveying speed as the external conveyor belt, and then conveys them to the roller 22. When the first detector 33 detects that the end of the steel plate is about to leave the conveyor roller 31, it controls the rotation speed of the conveyor roller 31 to decrease, thereby greatly reducing the inertia of the steel plate after it is conveyed to the roller 22, so that the steel plate can stop quickly. This avoids the problem of impact deformation caused by the use of a limiting structure to stop the steel plate in the traditional method, and improves the production quality and production continuity of the steel plate. At the same time, the fan 42 blows air to the bottom surface of the steel plate through the first exhaust hole 412, thereby forming a uniform air flow layer on the bottom surface of the steel plate on the conveyor roller 31, so as to provide an upward support force for the steel plate and offset the concave middle part of the steel plate due to its own weight. Subsequently, the third driving member 73 drives the first push plate 72 away from the first limit plate 71, providing a certain longitudinal displacement margin for the steel plate when it falls; the third self-driven slide 75 drives the second push plate 77 away from the second limit plate 76, providing a certain lateral displacement margin for the steel plate when it falls; thereby ensuring that the steel plate can stably fall onto the receiving platform 51 or the stacked steel plates. When the position sensor on the frame 1 detects that the steel plate is completely placed on the roller 22, the first driving member 23 drives the rocker 21 to swing and then reset, so that the steel plate can fall freely after being separated from the support of the roller 22, thereby achieving orderly stacking of the steel plates. The lifting platform 52 can automatically adjust the position of the receiving platform 51 according to the height of the stacked steel plates, ensuring that the steel plates always descend steadily during the stacking process, avoiding the problem of the steel plates sliding due to stacking too high or the steel plates tilting due to too large a height difference when they fall. Finally, when the steel plate falls onto the loading platform 51 or the stacked steel plates, the third driving member 73 drives the first push plate 72 to approach the first limit plate 71 to press the side of the steel plate parallel to its own conveying direction against the first limit plate 71; the third self-driven slide 75 drives the second push plate 77 to approach the second limit plate 76 to press the side of the steel plate close to the conveying roller 31 against the second limit plate 76, thereby eliminating the relative offset between the steel plates and improving the neatness of the steel plates after stacking.

[0047] Example 2 Reference Figure 3 and Figure 4 The main difference between this embodiment 2 and embodiment 1 is that it further includes a switch plate 9; an exhaust channel 211 is opened in the rocker arm 21; a fan blade 221 is provided on the roller 22; the ventilation seat 41 is located between the rocker arm 21 and the conveying roller 31; a U-shaped plate 8 is also provided on the ventilation seat 41; the ventilation seat 41 is also provided with a connecting hole 413, a second exhaust hole 414 and a feed trough 415.

[0048] Specifically, the exhaust passage 211 is opened on the swing rod 21 along the extension direction of the swing rod 21, and the exhaust passage 211 penetrates through both ends of the swing rod 21; the communication hole 413 is opened on the surface of the ventilation base 41 close to the swing rod 21 and communicates with the ventilation cavity 411; the rotating shaft of the roller 22 rotatably connected to the swing rod 21 extends into the exhaust passage 211, and the fan blade 221 is fixed on the rotating shaft of the roller 22. The shape of the fan blade 221 matches the cross-sectional shape of the exhaust passage 211. When the fan 42 blows air into the exhaust passage 211 through the communication hole 413, the fan blade 221 can drive the roller 22 to rotate, and the rotation direction of the roller 22 is opposite to the rotation direction of the conveying roller 31 on one side of the bottom surface of the steel plate; the material conveying groove 415 penetrates through the two surfaces of the ventilation base 41 close to the swing rod 21 and the conveying roller 31. The width of the material conveying groove 415 is close to that of the conveying roller 31, and the steel plate can be conveyed from the conveying roller 31 to the roller 22 through the material conveying groove 415.

[0049] In this way, when the steel plate is conveyed to the roller 22 through the material conveying groove 415 and contacts the roller 22, the roller 22 can drive the steel plate to move in the direction opposite to the conveying direction of the steel plate. This reverse movement can effectively reduce the forward sliding tendency of the steel plate due to inertia, thereby avoiding deformation or bending of the steel plate when it slides on the roller 22 and impacts the front object.

[0050] Refer to Figure 5 and Figure 6 In this embodiment, the U-shaped plate 8 is parallel to the horizontal plane and is located above the roller 22 to cover the steel plate on the roller 22. The U-shaped groove of the U-shaped plate 8 faces the side of the steel plate, and the extending direction of the U-shaped groove is parallel to the conveying direction of the steel plate; when there is a steel plate on the roller 22, an adsorption cavity 81 is formed between the U-shaped groove surface of the U-shaped plate 8 and the steel plate. The second exhaust hole 414 is opened on the surface of the ventilation base 41 close to the swing rod 21 and communicates with the adsorption cavity 81. In this way, when the steel plate is conveyed to the roller 22, an adsorption cavity 81 is formed between the U-shaped plate 8 and the steel plate on the roller 22. The gas in the ventilation cavity 411 enters the adsorption cavity 81 through the second exhaust hole 414 and is discharged from the end of the adsorption cavity 81 far from the ventilation base 41. After the gas flows at a high speed in the adsorption cavity 81, a pressure difference can be formed between the steel plate and the U-shaped plate 8 to promote the steel plate to approach the U-shaped plate 8, thereby offsetting the bending deformation of the steel plate due to its own weight.

[0051] Refer to Figure 6 and Figure 7, in this embodiment, the switch board 9 is slidably arranged on the ventilation base 41, and the sliding direction of the switch board 9 is perpendicular to the horizontal plane. The switch board 9 is in sealed sliding contact with the side of the ventilation base 41 close to the swing rod 21. A rack 91 is provided on the switch board 9, and the extending direction of the rack 91 is also perpendicular to the horizontal plane. A gear 212 meshing with the rack 91 is provided on the swing rod 21. The gear 212 is fixed on the connecting rod of the swing rod 21, and the rotation axis of the gear 212 is coaxial with the rotation axis of the swing rod 21. When the swing rod 21 swings, it can drive the switch board 9 to slide up and down through the gear 212 and the rack 91. When the two swing rods 21 approach each other, the swing rod 21 can drive the switch board 9 to cover the first exhaust hole 412 and open the second exhaust hole 414 and the communication hole 413 through the transmission of the gear 212 and the rack 91. When the two swing rods 21 move away from each other, the swing rod 21 can also drive the switch board 9 to cover the second exhaust hole 414 and the communication hole 413 and open the first exhaust hole 412 through the transmission of the gear 212 and the rack 91. A pressure relief valve is provided in the second exhaust hole 414. When the fan blade 221 rotates, the air pressure in the ventilation cavity 411 is less than the threshold value of the pressure relief valve. When the fan blade 221 stops rotating, the air pressure in the ventilation cavity 411 is greater than the threshold value of the pressure relief valve.

[0052] The implementation principle of Embodiment 2 is as follows: When the steel plate has not been conveyed onto the roller 22, the two swing rods 21 approach each other, and the switch board 9 covers the first exhaust hole 412 and opens the second exhaust hole 414 and the communication hole 413. The gas only discharges from the exhaust passage 211 to blow the fan blade 221 to rotate and drive the roller 22 to rotate, thereby providing a necessary pre-deceleration function when the subsequent steel plate contacts the roller 22. After the roller 22 contacts the steel plate, the roller 22 gradually decelerates until it stops rotating. The fan blade 221 blocks the exhaust passage 211 to increase the air pressure in the ventilation cavity 411 and exceed the set threshold value of the pressure relief valve. The gas then flows into the adsorption cavity 81 through the pressure relief valve to generate an adsorption force to offset the bending deformation of the steel plate due to its own weight. After the steel plate is positioned on the roller 22, the two swing rods 21 move away from each other to release the steel plate for free fall for stacking. When the swing rod 21 swings, it drives the switch board 9 to close the second exhaust hole 414 and the communication hole 413 and open the first exhaust hole 412. At this time, the gas in the ventilation cavity 411 only discharges from the first exhaust hole 412 to form a stable air flow layer below the steel plate, thereby providing support for the steel plate during the falling process and reducing the impact force when the steel plate falls; the dynamic switching of the gas flow direction is realized throughout the process, ensuring that the steel plate obtains appropriate gas support and guidance at different operation stages, effectively reducing the unnecessary loss of the air flow, and minimizing the energy waste to the greatest extent.

[0053] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
