Description

Technical Field

[0001] This invention relates to the field of automatic steel plate feeding technology, and in particular to an adjustable batch rectangular steel plate feeding assembly and feeding method. Background Technology

[0002] During the construction of nuclear power plants, a large number of threaded steel bar-rectangular steel plate embedded parts (hereinafter referred to as nuclear power embedded parts) are used. The nuclear power embedded parts include rectangular steel plates (hereinafter referred to as steel plates) and several threaded steel bars (hereinafter referred to as steel bars) vertically welded to one end face of the rectangular steel plate.

[0003] Welding of nuclear power plant embedded parts is typically performed using submerged arc welding machines for reinforcing bars. An automated welding production line designed based on submerged arc welding technology will significantly improve the manufacturing efficiency and product quality of nuclear power plant embedded parts. This automated welding production line includes at least functional modules such as steel plate loading, steel plate rust removal, welding assembly, and product unloading. Among these functional modules, achieving continuous and stable steel plate loading is the design challenge of the automated welding production line for nuclear power plant embedded parts. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an adjustable batch rectangular steel plate loading assembly and loading method. It is applied to an automated welding production line for nuclear power plant embedded parts, achieving continuous and stable steel plate loading.

[0005] The technical solution of this invention is: an adjustable batch rectangular steel plate loading assembly, including a steel plate storage device, a horizontal pusher device, and a small plate support device; the upper end of the steel plate storage device is provided with a storage area for defining the position of horizontally stacked steel plates, the bottom of the storage area is provided with a height-adjustable steel plate bearing surface, the top of the storage area is provided with a steel plate discharge surface with a fixed height, and the middle of the rear end of the steel plate storage device is provided with a concave area; the horizontal pusher device is located on the outer side of the front end of the steel plate storage device, and is used to push the steel plate at the upper end of the steel plate discharge surface to the outer side of the rear end of the steel plate storage device; the small plate support device is located in the concave area of ​​the steel plate storage device, and its upper end is provided with a steel plate transfer surface with two adjustable heights. When the steel plate transfer surface is at the high position, the steel plate transfer surface is flush with the steel plate discharge surface, and when the steel plate transfer surface is at the low position, the steel plate transfer surface is located at the lower end of the storage area.

[0006] A further technical solution of the present invention is as follows: The steel plate storage device includes a top plate, an upper plate, a lower plate, a bottom plate, a lifting drive component, angle steel, and pins; the top plate, upper plate, lower plate, and bottom plate are all horizontally arranged and sequentially arranged from top to bottom, the upper plate, lower plate, and bottom plate are fixedly connected as a whole, the top plate is movably mounted on the upper end of the upper plate through the lifting drive component, and the top plate moves vertically up and down under the drive of the lifting drive component to move away from or closer to the upper plate; the top plate is provided with four hollow strip-shaped adjustment holes A arranged in an X shape, two arbitrarily spaced adjustment holes A are collinearly arranged, and two arbitrarily adjacent adjustment holes A are collinearly arranged. The joint holes A form an included angle with each other. Each adjustment hole A has multiple limiting holes A arranged at intervals along its length, with the limiting holes A partially intersecting the adjustment holes A. The upper plate has a limiting hole B corresponding to the position of the limiting hole A on the top plate, and an adjustment hole B corresponding to the position of the adjustment hole A on the top plate. The lower plate has a limiting hole C corresponding to the position of the limiting hole B on the upper plate. The angle steel has two notches and a locking pin hole, allowing it to be in both locked and adjustable states. When the angle steel is in the locked state, it passes through the limiting hole A on the top plate, the limiting hole B on the upper plate, and the lower plate sequentially from top to bottom. The angle steel rests against the bottom plate through the limiting hole C. The two notches on the angle steel are offset from the upper and lower plates respectively. The pin is inserted into the locking pin hole of the angle steel and contacts the lower end face of the upper plate. At this time, the angle steel achieves horizontal positioning through the limiting hole A of the top plate, the limiting hole B of the upper plate, and the limiting hole C of the lower plate. At this time, the angle steel achieves vertical positioning through the pin and the bottom plate. When the angle steel is in the adjustment state, it passes through the limiting hole A of the top plate and the limiting hole B of the upper plate from top to bottom. The lower end of the angle steel does not contact the upper end face of the lower plate, and the locking pin hole of the angle steel is not inserted. The notches are located in the adjustment holes A of the top plate and B of the upper plate, respectively. At this time, the angle steel has not entered the limiting holes A of the top plate and B of the upper plate. The angle steel moves along the adjustment holes A of the top plate and B of the upper plate to achieve position adjustment. There are four angle steels. The four angle steels pass through the four limiting holes A on the top plate. The four limiting holes A intersect with the four adjustment holes A on the top plate. The top plate and the four angle steels together form a storage area for limiting the position of the horizontally stacked steel plates. The four angle steels in the locked state form the steel plate discharge surface at the same height at the upper edge.

[0007] A further technical solution of the present invention is as follows: the small plate support device includes a lower outer sleeve, an upper inner sleeve, linear bearings A, a transverse sleeve, a pull rod, and a spring; the lower outer sleeve is vertically arranged in the concave section, its lower end is fixedly installed on the lower plate, its upper end is located at the lower end of the top plate, and its outer surface is provided with a pull rod through hole A; the upper inner sleeve is movably fitted into the inner hole of the lower outer sleeve, its upper end extends out of the upper end of the lower outer sleeve, and its outer surface is provided with a pull rod through hole B corresponding to the position of the pull rod through hole A; multiple linear bearings A are rotatably installed on the upper end of the upper inner sleeve, and all linear bearings A are horizontal. The components are arranged in a rectangular array, thus forming the steel plate transmission surface at the upper end of all linear bearings A. The two ends of the transverse sleeve are a connecting end and a free end, respectively. The connecting end of the transverse sleeve is welded to the outer circumference of the lower outer sleeve and encloses the tie rod through-hole B. The transverse sleeve and the lower outer sleeve are arranged perpendicularly to each other, so that the inner hole of the transverse sleeve and the inner hole of the lower outer sleeve are connected through the tie rod through-hole A. The inner hole of the transverse sleeve consists of sequentially connected small-diameter sections and large-diameter sections, with an annular stepped surface A between the small-diameter and large-diameter sections. The tie rod has sequentially connected... The device consists of a large-diameter section and a small-diameter section, with an annular stepped surface B between them. The pull rod is movably installed in the inner hole of the transverse sleeve. A portion of the small-diameter section of the pull rod extends outside the free end of the transverse sleeve, and another portion of the small-diameter section slides into the small-diameter section of the transverse sleeve. The large-diameter section of the pull rod extends into the pull rod through hole A of the lower outer sleeve and slides into the pull rod through hole A of the lower outer sleeve. A spring is fitted onto the small-diameter section of the pull rod and located in the large-diameter section of the transverse sleeve, with both ends of the spring respectively engaging with the annular stepped surface of the transverse sleeve. A and the annular stepped surface B of the tie rod abut against each other; when the steel plate transmission surface is at the high position, the tie rod through hole B of the upper inner sleeve is directly opposite the tie rod through hole A of the lower outer sleeve, and the large diameter section of the tie rod passes through the tie rod through hole A of the lower outer sleeve and the tie rod through hole B of the upper inner sleeve in sequence under the action of the spring force, and abuts against the inner wall of the upper inner sleeve; when the steel plate transmission surface is at the low position, the tie rod through hole B of the upper inner sleeve is located at the lower end of the tie rod through hole A of the lower outer sleeve, and the large diameter section of the tie rod passes through the tie rod through hole A of the lower outer sleeve under the action of the spring force and abuts against the outer circular surface of the upper inner sleeve.

[0008] A further technical solution of the present invention is: the horizontal push plate device includes an electric push rod X disposed on the outer side of the front end of the steel plate storage device and a push plate connected to the end of the telescopic rod of the electric push rod X. The push plate performs horizontal reciprocating linear motion under the drive of the electric push rod X to move closer to or away from the small plate support device, thereby pushing the steel plate at the upper end of the steel plate discharge surface to the outer side of the rear end of the steel plate storage device.

[0009] A further technical solution of the present invention is: the upper ends of the four angle steels are provided with chamfered sections, and when the four angle steels are enclosed to form a storage area, the chamfered sections are inclined to the outside of the storage area; linear bearings B are rotatably connected to the outer sides of the upper ends of the four angle steels respectively, and when the four angle steels are enclosed to form a storage area, the linear bearings B are arranged horizontally and located outside the storage area.

[0010] The technical solution of the present invention is: a method for continuous feeding of rectangular steel plates, based on the above-mentioned adjustable batch rectangular steel plate feeding assembly, wherein the adjustable batch rectangular steel plate feeding assembly is in an initial state before the method is executed;

[0011] The initial state is as follows:

[0012] ①. Adjust the storage area in the steel plate storage device to match the size of the target steel plate;

[0013] ②. The top plate in the steel plate storage device rises to the uppermost point of its travel stroke;

[0014] ③. The telescopic rod of the electric push rod X in the horizontal push plate device is in the retracted state;

[0015] ④. If the steel plate support surface in the small plate support device is adjusted to the high position and the steel plate support surface is inside the storage area, then adjust the steel plate support surface to the low position; if the steel plate support surface in the small plate support device is adjusted to the high position and the steel plate support surface is outside the storage area, then adjust the steel plate support surface to the high position.

[0016] The method is as follows:

[0017] S01, Load the batch of steel plates into the storage area:

[0018] Several steel plates are hoisted to the storage area of ​​the steel plate storage device by a crane or electromagnetic chuck, ensuring that the uppermost steel plate is located below the steel plate discharge surface, and all steel plates are stacked in a stack under the restriction of four angle steels.

[0019] S02, Adjust the top steel plate to extend beyond the steel plate discharge surface:

[0020] The lifting drive component drives the top plate to rise, which in turn causes all the steel plates in the storage area to rise synchronously, so that the lower end of the uppermost steel plate exceeds the steel plate discharge surface by 0-2mm.

[0021] S03, the two actions work together to achieve continuous steel plate discharge:

[0022] A. The telescopic rod of the electric push rod X extends and pushes out a piece of steel plate at the upper end of the steel plate discharge surface; if the steel plate support surface is at a high position at this time, the steel plate enters the rolling conveying surface A of the front roller conveyor through the transmission of the steel plate support surface; if the steel plate support surface is at a low position at this time, the steel plate directly enters the rolling conveying surface A of the front roller conveyor.

[0023] B. The lifting drive component drives the top plate to rise to the height of one steel plate thickness, so that one steel plate at the lower end of the pushed-out steel plate extends out of the upper end of the steel plate discharge surface.

[0024] In this step, repeating steps A and B will achieve continuous steel plate output.

[0025] A further technical solution of the present invention is: a continuous feeding method for rectangular steel plates. In the initial state, step ①, the method for adjusting the size of the storage area is as follows: four angle steels are raised to a certain height so that the two notches on the angle steels are respectively in the adjustment hole A of the top plate and the adjustment hole B of the upper plate. Then the angle steels are moved along the adjustment holes A and B. When the angle steels move to the position that matches the target limiting hole A and the target limiting hole B, the angle steels are lowered so that the lower end of the angle steels passes through the limiting hole C of the lower plate and falls on the bottom plate, thereby realizing the adjustment of the size of the storage area.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] 1. This device is used for the stacking, storage, and automatic unloading of steel plates, and is a crucial component in the automated manufacturing of nuclear power plant embedded parts. The steel plate storage device can meet the stacking and storage needs of steel plates of different sizes, broadening its application range. It also allows for quick and convenient adjustment of the storage area size, making it more adaptable. Furthermore, it can achieve fixed-height steel plate output, facilitating connection with the horizontal pusher and front roller conveyor at both ends. The horizontal pusher is used to unload steel plates of different sizes, pushing them from the discharge surface at the top of the storage device onto the conveyor surface for subsequent processes. The small plate support device supports small steel plates discharged from the storage device, allowing them to smoothly enter the conveyor surface for subsequent processes.

[0028] 2. The operation of adjusting the size of the storage area of ​​the steel plate storage device is as follows: Raise the four angle steels to a certain height so that the two notches on the angle steels are in the adjustment hole A of the top plate and the adjustment hole B of the upper plate, respectively. Then move the angle steels along the adjustment holes A and B. When the angle steels move to the position that matches the target limit hole A and the target limit hole B, lower the angle steels so that the lower end of the angle steels passes through the limit hole C of the lower plate and falls on the bottom plate, thus realizing the adjustment of the size of the storage area.

[0029] 3. The principle of the steel plate storage device for fixed-height output of steel plates is as follows: The lifting drive component drives the top plate to rise and fall, thereby adjusting the height of the bottom surface at the lower end of the storage section. However, the height of the steel plate discharge surface at the upper end of the storage section remains unchanged. Therefore, whenever a steel plate at the upper end of the steel plate discharge surface is pushed out, the lifting drive component drives the top plate to rise a short distance, so that a steel plate at the lower end of the pushed-out steel plate extends out of the upper end of the steel plate discharge surface, thus achieving fixed-height output of steel plates.

[0030] 4. Design to improve reliability in steel plate storage device (Ⅰ): The angle steel is provided with locking pin holes. When the pin is inserted into the locking pin holes of the angle steel, the angle steel can be positioned vertically (at this time, the angle steel cannot be lifted). Based on this structure, it can avoid the situation where the thickness surface of the steel plate scrapes against the inner wall surface of the angle steel when the top plate drives the stack of steel plates placed on it to rise, causing the angle steel to rise through friction and the steel plate discharge surface to rise incorrectly.

[0031] 5. Design to improve reliability in steel plate storage device (II): An upper plate is provided between the top plate and the lower plate. The upper plate has a hole arrangement that is completely consistent with the top plate. Based on this structure, when the size of the storage area is adjusted, the adjustment hole A of the top plate and the adjustment hole B of the upper plate jointly provide the limit of the angle steel, maintain the stability of the angle steel during the movement along the adjustment hole A / adjustment hole B, so that when the angle steel moves to the position of the target limit hole A, it can be lowered to the bottom relatively quickly, accurately and smoothly.

[0032] 6. The steel plate storage device creates storage zones of varying sizes by adjusting the position of the angle steel. In larger storage zones, the steel plate discharge surface at the top is relatively close to the conveying surface of subsequent processes, eliminating the need for support and transfer after discharge. In smaller storage zones, the steel plate discharge surface is relatively far from the conveying surface of subsequent processes, requiring support and transfer after discharge. A small plate support device is located in the recessed area of ​​the steel plate storage device. It supports and transfers small steel plates discharged from the smaller storage zones, ensuring they can smoothly reach the conveying surface of subsequent processes.

Detailed Implementation

[0045] Example 1:

[0046] like Figure 1-9 As shown, the adjustable batch rectangular steel plate loading assembly includes a steel plate storage device 1, a horizontal pusher device 2, and a small plate support device 3.

[0047] The upper end of the steel plate storage device 1 is provided with a storage section 100 for defining the position of horizontally stacked steel plates. The bottom of the storage section 100 is provided with a height-adjustable steel plate bearing surface, and the top of the storage section 100 is provided with a steel plate discharge surface with a fixed height. The rear middle of the steel plate storage device 11 is provided with a recessed section 200. The steel plate storage device 1 includes a top plate 11, an upper plate 12, a lower plate 13, a bottom plate 14, a lifting drive component 15, an angle steel 16, and a pin 17.

[0048] The top plate 11, upper plate 12, lower plate 13 and bottom plate 14 are all arranged horizontally and arranged sequentially from top to bottom. The upper plate 12, lower plate 13 and bottom plate 14 are fixedly connected as a whole. The top plate 11 is movably installed on the upper end of the upper plate 12 through the lifting drive component 15. The top plate 11 moves vertically up and down under the drive of the lifting drive component 15 to move away from or closer to the upper plate 12, thereby increasing or decreasing the number of steel plates that the storage area 100 can accommodate. The area on the upper surface of the top plate 11 covered by the storage area 100 is the steel plate bearing surface. The top plate 11 has four X-shaped perforated adjustment holes A111. Two randomly spaced adjustment holes A111 are collinear, and any two adjacent adjustment holes A111 form an included angle. Each adjustment hole A111 has multiple spaced-apart limiting holes A112 (limiting holes A are V-shaped holes with a 90° included angle) arranged along its length. The limiting holes A112 partially intersect with the adjustment holes A111 (specifically, the V-shaped bend of the limiting hole A112 intersects with the adjustment hole A111). The upper plate 12 has limiting holes B121 corresponding to the positions of the limiting holes A112 on the top plate 11, and adjusting holes B122 corresponding to the positions of the adjustment holes A111 on the top plate 11. The lower plate 13 has limiting holes C131 corresponding to the positions of the limiting holes B121 on the upper plate 12.

[0049] Angle steel 16 has two notches 161 and a locking pin hole 162, and has two states: locked and adjustable. When angle steel 16 is in the locked state, angle steel 16 passes through the limiting hole A112 of the top plate 11, the limiting hole B121 of the upper plate 12 and the limiting hole C131 of the lower plate 13 from top to bottom and abuts against the bottom plate 14. The two notches 161 on angle steel 16 are offset from the upper plate 12 and the lower plate 13 respectively. The pin 17 is inserted into the locking pin hole 162 of angle steel 16 and contacts the lower end face of the upper plate 12. At this time, angle steel 16 is positioned horizontally by the limiting hole A112 of the top plate 11, the limiting hole B121 of the upper plate 12 and the limiting hole C131 of the lower plate 13. At this time, angle steel 16 is positioned vertically by the pin 17 and the bottom plate 14. When the angle steel 16 is in the adjustment state (this state requires holding the upper end of the angle steel 16 and lifting it to a certain height), the angle steel 16 passes through the limiting hole A112 of the top plate 11 and the limiting hole B121 of the upper plate 12 from top to bottom. The lower end of the angle steel 16 does not contact the upper end face of the lower plate 13. The locking pin hole 162 of the angle steel 16 is not inserted with the pin 17. The two notches 161 of the angle steel 16 are respectively in the adjustment hole A111 of the top plate 11 and the adjustment hole B121 of the upper plate 12. At this time, the angle steel 16 does not enter the limiting hole A112 of the top plate 11 and the limiting hole B121 of the upper plate 12. At this time, the angle steel 16 moves along the adjustment hole A111 of the top plate 11 and the adjustment hole B121 of the upper plate 12 to achieve position adjustment.

[0050] Four angle steels 16 are used, each passing through one of four limiting holes A112 that intersect with different adjusting holes A111. (The four limiting holes A112 are located at the same relative position to the intersecting adjusting holes A111; for example, each limiting hole A112 is located 3 cm from the inner end of the adjusting hole A111 (the inner end is the end relatively closer to the center of the top plate 11, and the outer end is the end relatively farther from the center of the top plate 11). This forms a storage area 100 between the top plate 11 and the four angle steels 16, defining the position of the horizontally stacked steel plates. Depending on the relative position of the limiting hole A112 and the adjusting hole A111 selected for the angle steel 16 (i.e., different settings are selected), the size of the storage area 100 is adaptively expanded or reduced, and the size of the steel plate accommodated in the storage area 100 is also adaptively expanded or reduced. The four angle steels 16, which are in a locked state, are at the same height at their upper edges to form the steel plate discharge surface.

[0051] A horizontal pusher device 2 is located on the outer front end of the steel plate storage device 1. It is used to push the steel plate at the upper end of the steel plate discharge surface towards the outer rear end of the steel plate storage device 1. The horizontal pusher device 2 includes an electric push rod X21 located on the outer front end of the steel plate storage device 1 and a pusher plate 22 connected to the end of the telescopic rod of the electric push rod X21. Driven by the electric push rod X21, the pusher plate 22 performs a horizontal reciprocating linear motion to move closer to or further away from the small plate support device 3, thereby pushing the steel plate at the upper end of the steel plate discharge surface towards the outer rear end of the steel plate storage device 1 (the pusher plate 22 contacts the thickness surface of the steel plate when pushing it). When the telescopic rod of the electric push rod X21 is in the retracted state, the entire horizontal pusher device 2 is located outside the largest storage area 100.

[0052] The small plate support device 3 is installed in the concave section 200 of the steel plate storage device 1, and its upper end is provided with a steel plate transfer surface that can be adjusted to two levels (high and low). When the steel plate transfer surface is at the high level, it is flush with the steel plate discharge surface. At this time, the steel plate transfer surface is used to receive and transfer the steel plate pushed out by the horizontal pusher device 2, so that the steel plate can smoothly enter the conveying surface of the subsequent process. When the steel plate transfer surface is at the low level, it is located at the lower end of the storage section 100. At this time, the steel plate transfer surface avoids interference with the steel plate placed in the storage section 100. The small plate support device 3 includes a lower outer sleeve 31, an upper inner sleeve 32, a linear bearing A33, a transverse sleeve 34, a pull rod 35, and a spring 36.

[0053] The lower outer sleeve 31 is vertically arranged in the recessed section 200, with its lower end fixedly mounted on the lower plate 13 and its upper end located below the top plate 11. A tie rod through hole A is provided on its outer circular surface. The upper inner sleeve 32 is movably fitted into the inner hole of the lower outer sleeve 31, with its upper end extending beyond the upper end of the lower outer sleeve 31. A tie rod through hole B corresponding to the position of tie rod through hole A is provided on its outer circular surface. Multiple linear bearings A33 are rotatably mounted on the upper end of the upper inner sleeve 32. All linear bearings A33 are horizontally arranged in a rectangular array, thus forming the steel plate transmission surface at the upper ends of all linear bearings A33. The two ends of the transverse sleeve 34 are the connecting end and the free end, respectively. The connecting end of the transverse sleeve 34 is welded to the outer circular surface of the lower outer sleeve 31 and encloses the tie rod through hole B. The transverse sleeve 34 and the lower outer sleeve 31 are arranged perpendicular to each other, so that the inner hole of the transverse sleeve 34 and the inner hole of the lower outer sleeve 31 are connected through the tie rod through hole A on the lower outer sleeve 31. The inner hole of the transverse sleeve 34 is composed of a small diameter section and a large diameter section connected in sequence. An annular step surface A is provided between the small diameter section and the large diameter section. The pull rod 35 consists of a large-diameter section and a small-diameter section connected in sequence. An annular stepped surface B is provided between the large-diameter section and the small-diameter section. The pull rod 35 is movably installed in the inner hole of the transverse sleeve 34. A portion of the small-diameter section of the pull rod extends outside the free end of the transverse sleeve 34, and a portion of the small-diameter section of the pull rod 35 slides into the small-diameter section of the transverse sleeve 34. The large-diameter section of the pull rod 35 extends into the pull rod through hole A of the lower outer sleeve 31 and slides into the pull rod through hole A of the lower outer sleeve 31. A spring 36 is fitted onto the small-diameter section of the pull rod 35 and located in the large-diameter section of the transverse sleeve 34. Both ends of the spring 36 abut against the annular stepped surface A of the transverse sleeve 34 and the annular stepped surface B of the pull rod 35, respectively. When the steel plate transmission surface is at a high position, the pull rod through hole B of the upper inner sleeve 32 is directly opposite the pull rod through hole A of the lower outer sleeve 31. Under the elastic force of the spring 36, the larger diameter section of the pull rod 35 passes through the pull rod through hole A of the lower outer sleeve 31 and the pull rod through hole B of the upper inner sleeve 32 in sequence, and abuts against the inner wall of the upper inner sleeve 32. When the steel plate transmission surface is at a low position, the pull rod through hole B of the upper inner sleeve 32 is located at the lower end of the pull rod through hole A of the lower outer sleeve 31. Under the elastic force of the spring 36, the larger diameter section of the pull rod 35 passes through the pull rod through hole A of the lower outer sleeve 31 and abuts against the outer surface of the upper inner sleeve 32.

[0054] Preferably, the upper ends of the four angle steels 17 are provided with chamfered sections. When the four angle steels 17 are closed to form the storage area 100, the chamfered sections are inclined outward from the storage area 100, which serves to prevent the steel plate from hitting the angle steel due to misalignment and to guide the steel plate to be lowered into the storage area 100. Linear bearings B18 are rotatably connected to the outer sides of the upper ends of the four angle steels 17 respectively. When the four angle steels 17 are closed to form the storage area 100, the linear bearings B18 are horizontally arranged and located outside the storage area 100, which serves to prevent the steel plate from hitting the angle steel due to misalignment and to guide the steel plate to be lowered into the storage area 100.

[0055] A method for continuous feeding of rectangular steel plates, based on the aforementioned adjustable batch rectangular steel plate feeding assembly, wherein the adjustable batch rectangular steel plate feeding assembly is in an initial state before the method is executed.

[0056] The initial state is as follows:

[0057] 1. The storage section 100 in the steel plate storage device 1 is adjusted to be compatible with the size of the target steel plate;

[0058] 2. The top plate 11 in the steel plate storage device 1 rises to the uppermost point of its travel stroke;

[0059] 3. The telescopic rod of the electric push rod X21 in the horizontal push plate device 2 is in the retracted state;

[0060] 4. If the steel plate support surface in the small plate support device 3 is adjusted to the high position and the steel plate support surface is inside the storage area 100, then the steel plate support surface is adjusted to the low position; if the steel plate support surface in the small plate support device 3 is adjusted to the high position and the steel plate support surface is outside the storage area 100, then the steel plate support surface is adjusted to the high position.

[0061] The method is as follows:

[0062] S01, Load the batch of steel plates into the storage area:

[0063] Several steel plates are hoisted to the storage area of ​​the steel plate storage device by a crane or electromagnetic chuck, ensuring that the uppermost steel plate is located below the steel plate discharge surface, and all the steel plates are stacked in a pile under the restriction of four angle steel bars.

[0064] S02, Adjust the top steel plate to extend beyond the steel plate discharge surface:

[0065] The lifting drive component 15 drives the top plate to rise, which in turn causes all the steel plates in the storage area 100 to rise synchronously, so that the lower end of the uppermost steel plate exceeds the steel plate discharge surface by 0-2mm.

[0066] S03, the two actions work together to achieve continuous steel plate discharge:

[0067] A. The telescopic rod of the electric push rod X21 extends and pushes out a steel plate at the upper end of the steel plate discharge surface; if the steel plate support surface is at a high position at this time, the steel plate enters the rolling conveying surface A of the front roller conveyor 41 through the transmission of the steel plate support surface; if the steel plate support surface is at a low position at this time, the steel plate directly enters the rolling conveying surface A of the front roller conveyor 41.

[0068] B. The lifting drive component drives the top plate to rise to the height of one steel plate thickness, so that one steel plate at the lower end of the pushed-out steel plate extends out of the upper end of the steel plate discharge surface.

[0069] In this step, repeating steps A and B will achieve continuous steel plate output.
