Description

Technical Field

[0001] This invention relates to sorting technology before sheet material processing, specifically an automated sheet material sorting system and a slab sorting method. Background Technology

[0002] Wood flooring refers to flooring made of wood. With the continuous progress of society and the rapid development of the decoration industry, the installation of wood flooring has brought people a beautiful visual experience, and the installation of wood flooring is becoming more and more popular in the decoration industry. During the processing of wood flooring, due to the uncertainty of the coloring process, the color of some wood blocks will vary. Therefore, it is necessary to classify wood flooring according to the depth of its surface color.

[0003] A search of Chinese public document CN116532393A—Solid Wood Flooring Grading and Palletizing Production Line—reveals that, in paragraphs [0096-0104] of the specification, the following is stated: By activating the conveying mechanism, the pusher seat circulates below the storage mechanism; when the pusher seat's assist part contacts the edge of the bottom solid wood flooring, the bottom solid wood flooring is pulled through the discharge port by the transmission mechanism and conveyed into the photographing device. [0077-0079] discloses the use of front and rear baffles, forming a placement cavity adapted to the solid wood flooring between them, with the discharge port located between the front baffle and the conveying mechanism.

[0004] In this structure, when the conveying mechanism transports the bottom slab, one side of the slab falls onto the conveying mechanism first. As the slab falls completely onto the conveying mechanism, the stack of slabs above the bottom slab will also tilt at a certain angle. Due to the tilt, the slabs on the upper side will get stuck in the placement cavity formed by the front and rear baffles. At the same time, the placement cavity can hold a small number of slabs at a time. This type of placement cavity design is not conducive to the efficient transport of floor slabs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is that the existing slab sorting line is prone to jamming when the slab is tilted during the slab conveying process, which makes it impossible to achieve efficient, automatic, continuous and stable slab feeding and thus cannot efficiently complete the slab sorting work.

[0006] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this invention, which adopts the following technical solution:

[0007] An automated board sorting system includes:

[0008] The slab stacking conveyor line is suitable for continuous feeding and conveying of slabs from a whole stack into single stacks.

[0009] Slab feeding conveyor line, slab stack feeding conveyor line is suitable for continuous feeding and conveying of single stack slabs into single slabs;

[0010] The slab feeding conveyor line includes a slab conveyor belt and a limiting frame installed on the top of the slab conveyor belt. A gap is reserved between the bottom of the limiting frame and the slab conveyor belt to facilitate the conveying of single slab blanks. A slab pressing cylinder is installed on the limiting frame. The slab pressing cylinder is suitable for vertically pressing the slab stacks conveyed by the slab stack feeding conveyor line. The piston end of the slab pressing cylinder is connected to a slab pressing plate through a ball head structure. The slab pressing plate is located on the top of the slab stack near the limiting frame.

[0011] Slab sorting line: The slab sorting line is suitable for sorting out the corresponding slabs in conjunction with lighting.

[0012] Specifically, the slab stack feeding conveyor line continuously feeds slabs from the entire stack into individual stacks. This method of continuous single-board feeding differs from previous methods in that a slab pressing plate and a slab pressing cylinder are connected by a ball joint structure. The slab pressing cylinder drives the pressing plate to press down on the top of the stack, and the slab conveyor belt at the bottom continuously conveys the slabs from the stack one by one. The height of the stack continuously decreases. During the single-board feeding and conveying, the stack of remaining slabs will tilt. The slab pressing plate can be relatively deflected by the ball joint structure. After the deflection, the stability of the stack will decrease, thus placing the slab pressing plate on the side of the top of the stack near the limit frame. That is, pressing the rear side of the top of the stack ensures the stability of the stack and prevents collapse.

[0013] Preferably, a limiting plate is installed on the facing side of the limiting frame, and the vertical height of the limiting plate relative to the slab conveyor belt is adjustable; the adjustable height of the limiting plate is suitable for adjusting the height.

[0014] The back of the limiting frame is equipped with a cleaning pipe and a blowing air port is provided on the cleaning pipe. The blowing air port is suitable for cleaning debris from the surface of the slab. The debris on the surface of the slab is cleaned through the cleaning pipe.

[0015] Both sides of the feed end of the slab conveyor belt are equipped with straightening roller assemblies. The straightening roller assembly is equipped with three sets of rollers. The bottom slab of the stack will first contact the slab conveyor belt and be located between the middle roller and the roller on the side away from the limit frame as it moves away from the limit frame. Then, as the bottom slab completely leaves the stack, the bottom slab will be able to immediately achieve a horizontal state on the slab conveyor belt under the action of the middle roller and the roller on the side closer to the limit frame.

[0016] Preferably, the top two ends of the limiting frame are equipped with brackets, an adjusting screw is vertically installed on the brackets and a connecting seat is rotatably installed at the bottom of the adjusting screw, the connecting seat is installed on the front plate side of the limiting plate by bolts, a slider is installed on the back plate side of the limiting plate, and a vertical guide rail is vertically installed on the front plate side of the limiting frame, the vertical guide rail and the slider are in sliding cooperation.

[0017] Specifically, by adjusting the screw, the connecting seat and the limiting plate are moved up and down via the slider and the vertical guide rail, thereby adjusting the height of the limiting plate to facilitate the smooth passage of the single-plate blank.

[0018] Preferably, the pallet loading conveyor line includes a pallet conveyor belt and pallet conveying cylinders located on both sides of the pallet stack. Mounting frames are installed on both sides of the output end of the pallet conveyor belt. Movable frames are installed on the piston ends of the two sets of pallet conveying cylinders. Horizontal guide rails are installed at the bottom of the movable frames. The horizontal guide rails are arranged horizontally in a direction perpendicular to the limiting frame. A crossbeam is installed at the bottom of the horizontal guide rails. Clamping parts for clamping the ends of the pallet stack are installed on both sets of movable frames. Vertical pressing parts for pressing the pallet stack are installed on the top of the clamping parts and the mounting frames.

[0019] The clamping part includes a mounting plate, which is provided with two sets of end face clamping cylinders respectively installed on the side of the movable frame opposite to the limiting frame. The end face clamping cylinders are installed on the side of the mounting plate opposite to the plate stack. The end face clamping plates are installed at the ends of the end face clamping cylinders and slide relative to the side of the movable frame opposite to the limiting frame.

[0020] The pressing part includes vertically arranged plate pressing cylinders. The plate pressing cylinders are installed on the top of the end face clamping plate. The piston end of the plate pressing cylinder is equipped with a plate pressing plate through a ball head structure. The plate pressing plate of the clamping part is located on the side of the top of the single stack of slabs away from the moving frame.

[0021] Specifically, the single stack of slabs to be transported is pressed and fixed by the slab pressing cylinder on the mounting frame via the slab pressing plate, and the clamping part on the moving frame will clamp the single stack of slabs to be transported from front to back. The slabs on the right side are pressed and fixed by the slab pressing cylinder on the moving frame via the slab pressing plate, and the moving frame is moved to the right by the slab conveying cylinder, and transported to the slab conveyor belt for continuous feeding of individual slabs.

[0022] Preferably, the tail end of the slab sorting line is also provided with a slab stacking line, which is suitable for re-stacking the sorted slabs.

[0023] The slab stacking line includes a stacking conveyor belt with its feed end lower than the slab sorting line. Uprights are installed on both sides of the feed end of the stacking conveyor belt, and a connecting frame is installed on the top of the uprights. A baffle is installed on the receiving side of the connecting frame, which is suitable for controlling the stack height of a single stack of slabs. Support frames are installed on both sides of the bottom of the baffle, and support cylinders are installed at the bottom of both support frames. The support cylinders are suitable for raising and lowering the support frames. A stacking assembly is installed at the bottom of the slab sorting line, which is suitable for organizing single stacks of slabs and conveying them to the rear.

[0024] Specifically, the sorted slabs are re-stacked and arranged by the stacking and feeding assembly, and the bottom of the stack is supported by the support cylinder and the support frame. The height of the single stack is controlled by the baffle.

[0025] Preferably, the stacking conveyor belt consists of two conveyor belts arranged in parallel.

[0026] Preferably, the stacking assembly includes a pusher cylinder and a pusher frame, wherein the pusher cylinder is located at the bottom of the slab sorting line and is adapted to drive the pusher frame to move back and forth;

[0027] A pressure-applying component is installed below the pusher frame;

[0028] The pusher has integrated plates installed on both the left and right sides. The two integrated plates can move left and right relative to the pusher. A connecting rod is rotatably installed at the bottom of each integrated plate. A swing arm is rotatably installed at the free end of the connecting rod through a pin. The swing arm is rotatably installed at the bottom of the integrated plate. A torsion spring is installed at the rotation node of the swing arm. The swing arm is suitable for deflection movement under the action of the pressure component.

[0029] The pressure-applying component is suitable for adjusting the single stack of slabs by deflecting the swing arm and moving the two integrated plates toward the center of the pusher frame.

[0030] Both integrated panels are equipped with integrated rubber wheels on opposite sides, which are suitable for left and right deflection relative to the integrated panels.

[0031] Specifically, the pusher is driven to move the pusher frame to the right by the pusher cylinder, and the stack of plates that meet the design elevation dimensions are transported and sorted. During the transport process, the swing arm will rotate under the obstruction of the pressure component. The connecting rod completes the integration of the plates and brings them closer to each other. The integration rubber wheels on it perform front-to-back and left-to-right straightening of the plates of different heights in the stack, ensuring that the stack is neat and orderly.

[0032] Preferably, the top of the integrated plate is flush with the pusher frame and the cross-section of the integrated plate is an L-shaped plate;

[0033] The integrated rubber wheel includes a rotating body and a rubber wheel body. The rotating body is mounted on the integrated plate via a rotating shaft. The rotating body has a "<" shaped structure and its free end is suitable for mounting the rubber wheel body. A spring is mounted on the rotating body, and the free end of the spring is mounted on the integrated plate.

[0034] After the integrated plates approach each other, the rotating body clamps and straightens the four corners of the plate stack via rubber wheels. When the integrated plates move away from each other, the rotating body can be reset by springs.

[0035] Preferably, the slab sorting line includes a sorting conveyor belt and a defective product conveyor belt, and the tail end of the defective product conveyor belt is provided with a slab stacking line.

[0036] A method for sorting slabs in an automated sheet metal sorting system is as follows:

[0037] Step 1: Conveying whole stacks of slabs into single stacks of slabs

[0038] The entire stack of slabs is loaded onto the slab loading conveyor line by a robotic arm. The slab blanks are then transported from the entire stack to individual stacks via the slab loading conveyor line. The slab pressing cylinder on the mounting frame drives the slab pressing plate to press down on the individual stack of slab blanks. The pressing point of the pressing plate on the top of the slab blank is located on the side away from the moving frame. The end face clamping cylinder drives the corresponding end face clamping plate to clamp the end face of the individual stack of slab blanks. The slab pressing cylinder on the mounting plate drives the slab pressing plate to press down on the individual stack of slab blanks. The pressing point of the pressing plate on the top of the slab blank is located on the side away from the moving frame. The slab conveying cylinder drives the moving frame to convey the slab blanks onto the slab conveyor belt along the horizontal guide rail.

[0039] Step 2: Conveying single stacks of slabs into single-panel slabs

[0040] The single stack of slabs conveyed by the slab stack feeding conveyor on the slab conveyor belt is pressed and stabilized by the slab pressing cylinder on the limit frame and the slab pressing plate. The pressing point of the slab pressing plate at the top of the single stack of slabs is located on the side close to the limit frame, and at this time the slab is attached to the limit plate. The end face clamping plate presses the slab stack vertically at the first moment when the end of the stack is released. The slab conveyor belt drives the bottom slabs to be conveyed one by one. During the conveying process, the slab pressing plate ensures the stability of the stack. The single slabs are conveyed one by one through the gap at the bottom of the limit frame. The blowing air port on the cleaning pipe cleans the debris on the surface of the single slabs.

[0041] Step 3: Sorting

[0042] The external CDD inspection mechanism, in conjunction with lighting, performs intelligent quality inspection on the slabs and sorts out those that do not meet the requirements. The slabs that do not meet the requirements are conveyed by the defective product conveyor belt, while the slabs that meet the requirements are conveyed by the sorting conveyor belt.

[0043] Step 4: Stacking and Consolidation

[0044] The slabs, which continue to be conveyed by the sorting conveyor belt, fall onto the support frame under the action of the baffle. When they are stacked to a suitable thickness, the piston end of the support cylinder drives the upper surface of the support frame to move down to be flush with the bottom surface of the pusher frame. The piston end of the pusher cylinder drives the pusher frame to push the stacked slabs onto the stacking conveyor belt. During the push, the swing arm will come into contact with the pressure component, forcing the swing arm to rotate. Through the connecting rod, the integrated plates on both sides move towards the side closer to the pusher frame. At this time, the stacked slabs are already on the stacking conveyor belt. As the swing arm continues to deflect, it drives the integrated plates to move further towards the center of the pusher frame. The stack is then aligned in all directions by the integrated rubber wheels. The pusher cylinder drives the pusher frame to reset, and the swing arm is also reset synchronously by the torsion spring.

[0045] Step 5: Palletizing

[0046] The stacked pallets are then re-stacked by a robotic arm.

[0047] Compared with the prior art, the present invention has the following beneficial effects:

[0048] This invention converts slabs from a whole stack to a single stack via a slab stacking conveyor line, then converts the single stack to a single slab via another slab stacking conveyor line, and then sorts out slabs that do not meet the requirements via a CCD detection mechanism and lighting on a slab sorting conveyor line, thus completing the efficient slab sorting process. Finally, the slabs are automatically stacked via a slab stacking line.

[0049] This invention utilizes a slab stack feeding conveyor line to continuously feed slabs from entire stacks, and then feeds individual slabs from each stack. This method of continuous single-panel feeding differs from previous methods in that a slab pressure plate and a slab pressing cylinder are connected via a ball joint structure. The pressing cylinder drives the pressure plate to press down on the top of the stack, and a bottom slab conveyor belt continuously transports the slabs from the stack, causing the stack height to continuously decrease. During the single-panel feeding process, the remaining slabs... The stack of blanks will tilt. The blank pressure plate can be deflected relative to it through the ball head structure. After the deflection, the stability of the stack will be worse. As a result, the blank pressure plate will be located on the side of the top of the stack near the limit frame. That is, the back side of the top of the stack is pressed to ensure the stability of the stack and prevent collapse. This eliminates the problem of blanks getting stuck in the space during the conveying process when using a semi-enclosed space (placement cavity) structure design. This design can achieve efficient, automatic, continuous and stable feeding of blanks and efficiently complete the blank sorting work.

[0050] After sorting, the slabs of this invention are pushed to the right by a pushing cylinder, which moves the slabs to the right at the designed elevation. The invention also straightens the four corners of the stacked slabs and corrects the stack's deviation to prevent the stack from becoming loose during transport.

[0051] In the pallet stacking conveyor line of the present invention, the pressure plate connected to the pallet stack pressing cylinder on the mounting plate is located on the top of the pallet stack away from the moving frame, pressing and fixing the single stack. This setting enables the right side of the pallet stack to be attached to the facing side of the limiting plate. The limiting plate limits the right side of the single stack of slab blanks, ensuring that the slab blanks remain attached to the facing side of the limiting plate during continuous conveying, preventing the single stack of slab blanks from becoming loose.

[0069] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0070] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0071] Example 1, such as Figure 1 and Figure 2 As shown, an automated board sorting system includes:

[0072] The 10 pallet stacking conveyor line is suitable for continuous feeding and conveying of a whole stack of slabs into single stacks.

[0073] Slab feeding conveyor line 20 and slab stack feeding conveyor line 10 are suitable for continuous feeding and conveying of single stack slabs into single slabs.

[0074] The slab feeding conveyor line 20 includes a slab conveyor belt 21 and a limiting frame 22 installed on the top of the slab conveyor belt 21. A gap is reserved between the bottom of the limiting frame 22 and the slab conveyor belt 21 to facilitate the conveying of single slab slabs. A slab pressing cylinder 23 is installed on the limiting frame 22. The slab pressing cylinder 23 is suitable for vertically pressing the slab stacks conveyed by the slab stack feeding conveyor line 10. The piston end of the slab pressing cylinder 23 is connected to a slab pressing plate 24 through a ball head structure. The slab pressing plate 24 is located on the top of the slab stack near the limiting frame 22. By controlling the air intake of the slab pressing cylinder 23, the remaining slab stacks can be adaptively pressed according to the height of the slab stack.

[0075] Slab sorting line 30 is suitable for sorting out corresponding slabs in conjunction with lighting.

[0076] The whole stack of slabs is loaded onto the slab loading conveyor line 10 by a robot. The slabs are then transported from the whole stack to the single stack via the slab loading conveyor line 10. The single stacks are then transported to the single slabs via the slab loading conveyor line 20. The slabs are then transported to the single slabs via the slab sorting line 30 with the help of lights. Slabs that do not meet the requirements are then sorted out, thus completing a highly efficient and automated slab sorting process.

[0077] The slab stack feeding conveyor line 10 continuously feeds entire stacks of slabs into individual stacks, while the slab stack feeding conveyor line 20 continuously and stably feeds individual slabs from individual stacks. This method of continuous single-slab feeding differs from the past. Specifically, the slab pressing plate 24 and the slab pressing cylinder 23 are connected and installed via a ball joint structure. The slab pressing cylinder 23 drives the pressing plate 24 to press down on the top of the stack, and the slab conveyor belt 21 at the bottom continuously conveys the slabs from the stack one by one. The height of the stack will continuously decrease. When the single-slab slabs are fed and conveyed, the stack composed of the remaining slabs will tilt at a certain angle. The slab pressing plate 24 can be relatively deflected through the ball joint structure. After the deflection, the stability of the stack will decrease, so that the slab pressing plate 24 is located on the side of the top of the stack near the limit frame 22, that is, pressing the rear side of the top of the stack to ensure the stability of the stack and prevent collapse.

[0078] Example 2, based on the above examples, makes the following improvements, such as... Figure 3 , Figure 4 , Figure 6As shown, a limiting plate 221 is installed on the receiving side of the limiting frame 22. The vertical height of the limiting plate 221 relative to the slab conveyor belt 21 is adjustable. The height of the limiting plate is adjustable to adjust the height. After the remaining slab stack tilts at a certain angle, the feeding side will press against the back plate side of the limiting plate. The slab pressing plate 24 at the top of the back plate side will press the slab stack down. Immediately after the slab is conveyed, the bottom slab will return to a horizontal state for conveying. This structure can achieve a stable and continuous conveying effect and ensure the stability of the slab stack during the process. Even after the bottom slab is conveyed, the next bottom slab will automatically fall back to a horizontal state and be conveyed immediately.

[0079] The back of the limiting frame 22 is equipped with a cleaning pipe 222 and a blowing air port is provided on the cleaning pipe 222. The blowing air port is suitable for cleaning debris on the surface of the slab. The debris on the surface of the slab is cleaned through the cleaning pipe 222 and the blowing air port.

[0080] Both sides of the feed end of the slab conveyor belt 21 are equipped with straightening roller assemblies 211. The straightening roller assembly is equipped with three sets of rollers in total, on the left, middle and right. The bottom slab of the stack will first contact the slab conveyor belt 21 and be located between the middle roller and the roller on the side away from the limit frame 22 when it is far away from the limit frame 22. Then, as the bottom slab completely leaves the stack, the bottom slab will be able to immediately be in a horizontal state on the slab conveyor belt under the action of the middle roller and the roller on the side close to the limit frame 22.

[0081] Example 3, based on the above example, makes the following improvement: Supports 223 are installed at both ends of the top of the limiting frame 22. An adjusting screw 224 is vertically installed on the support 223, and a connecting seat 225 is rotatably installed at the bottom of the adjusting screw 224. The connecting seat 225 is bolted to the facing side of the limiting plate 221. A slider 226 is installed on the back side of the limiting plate 221. A vertical guide rail 227 is vertically installed on the facing side of the limiting frame 22, and the vertical guide rail 227 and slider 226 are in sliding engagement. By adjusting the screw 224, the connecting seat 225 and the limiting plate 221 are adjusted vertically via the slider 226 and the vertical guide rail 227, thereby achieving height adjustment of the limiting plate 221 to facilitate the smooth passage of the single-plate blank.

[0082] Example 4, based on the above examples, makes the following improvements, such as... Figure 2 , Figure 5As shown, the pallet loading conveyor line 10 includes a pallet conveyor belt 11 and pallet conveying cylinders 12 located on both sides of the pallet. Mounting frames 13 are installed on both sides of the output end of the pallet conveyor belt 11. Moving frames 15 are installed on the piston ends of the two sets of pallet conveying cylinders 12. Horizontal guide rails 14 are installed at the bottom of the moving frames 15. The horizontal guide rails 14 are arranged horizontally in a direction perpendicular to the limiting frame 22. A crossbeam is installed at the bottom of the horizontal guide rails 14. Clamping parts for clamping the ends of the pallet are installed on both sets of moving frames 15. Vertical pressing parts for pressing the pallet are installed on the top of the clamping parts and the mounting frames 13.

[0083] The clamping part includes a mounting plate 16, which is provided with two sets of end face clamping cylinders 17 respectively installed on the side of the movable frame 15 opposite to the limiting frame 22. The end face clamping cylinders 17 are installed on the side of the mounting plate 16 opposite to the stack of plates. The end face clamping cylinders 17 are equipped with end face clamping plates 18, which slide relative to the side of the movable frame 15 opposite to the limiting frame 22.

[0084] The pressing part includes a vertically arranged plate pressing cylinder 19, which is installed on the top of the end face clamping plate 18. The piston end of the plate pressing cylinder 19 is equipped with a plate pressing plate 110 through a ball head structure. The plate pressing plate 110 of the clamping part is located on the side of the top of the single stack of slabs away from the moving frame 15.

[0085] The pallet conveying cylinder 12 drives the moving frame 15 to move to the right, which clamps and fixes the single stack of slabs by the end face clamping cylinder 17 through the piston end of the end face clamping plate 18. The bottom of the end face clamping plate 18 is provided with a horizontal support plate close to the bottom of the pallet stack. After the pallet stack is clamped and fixed by the end face clamping plate 18, it is then vertically pressed and fixed by the pallet stack pressing cylinder 19 and the single stack pressing plate 110. The vertical pressing and fixing can ensure the stability of the single stack of slabs during the conveying process. The pallet stack pressing plate 110 of the clamping part is located on the side of the top of the single stack of slabs away from the moving frame 15, which is suitable to ensure that the single stack of slabs can be attached to the facing side of the limiting plate 221 after the pallet stack is conveyed. This is beneficial to ensure that the right side of the pallet stack is always attached to the limiting plate 221 when the slabs are continuously conveyed, thus ensuring the stability of the pallet stack during continuous conveying and preventing loosening.

[0086] Example 5, based on the above examples, makes the following improvements, such as... Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 As shown, a slab stacking line 40 is also provided at the tail end of the slab sorting line 30, which is suitable for re-stacking the sorted slabs.

[0087] The slab stacking line 40 includes a stacking conveyor belt 41 with its feed end lower than the slab sorting line 30. Uprights 42 are installed on both sides of the feed end of the stacking conveyor belt 41. A connecting frame 43 is installed on the top of the uprights 42. A baffle 413 is installed on the receiving side of the connecting frame 43. The baffle 413 is suitable for controlling the stack height of a single stack of slabs. Supporting frames 44 are installed on both sides of the bottom of the baffle 413. Supporting cylinders 45 are installed at the bottom of both supporting frames 44. The supporting cylinders 45 are suitable for raising and lowering the supporting frames 44. A whole-stack conveying assembly is installed at the bottom of the slab sorting line 30. The whole-stack conveying assembly is suitable for sorting single stacks of slabs and conveying them to the rear.

[0088] The stacking conveyor belt 41 consists of two conveyor belts arranged in parallel.

[0089] The stacking and feeding assembly includes a push cylinder 47 and a push frame 48. The push cylinder 47 is located at the bottom of the slab sorting line 30 and is adapted to drive the push frame 48 to move back and forth.

[0090] A pressure-applying component 46 is installed below the pusher frame 48; the pressure-applying component 46, the supporting cylinder 45, the pushing cylinder 47 and the pusher frame 48 are all on the same platform, and the pusher frame 48 slides horizontally relative to the platform.

[0091] An integrated plate 49 is installed on both the left and right sides of the pusher frame 48. The two integrated plates 49 can move left and right relative to the pusher frame 48. A connecting rod 410 is rotatably installed at the bottom of each integrated plate 49. A swing arm 411 is rotatably installed at the free end of the connecting rod 410 through a pin. The swing arm 411 is rotatably installed at the bottom of the integrated plate 49. A torsion spring is installed at the rotation node of the swing arm 411. The swing arm 411 is suitable for deflection under the action of the pressure member 46.

[0092] The pressure component 46 is adapted to deflect the swing arm 411, causing the two integrated plates 49 to move toward the middle of the pusher frame 48 to adjust the single stack of slab blanks;

[0093] Two integrated plates 49 are each equipped with an integrated rubber wheel 412 on opposite sides. The integrated rubber wheel 412 is adapted to deflect left and right relative to the integrated plate 49.

[0094] The top of the integrated plate 49 is flush with the pusher 48, and the cross-section of the integrated plate 49 is an L-shaped plate.

[0095] The integrated rubber wheel 412 includes a rotating body 4121 and a rubber wheel body 4122. The rotating body 4121 is mounted on the integrated plate 49 via a rotating shaft. The rotating body 4121 has a "<" shaped structure and its free end is suitable for mounting the rubber wheel body 4122. A spring 4123 is mounted on the rotating body 4121 and the free end of the spring 4123 is mounted on the integrated plate 49.

[0096] After sorting at the tail end of the slab sorting line 30, the slabs continue to be conveyed to the right and stacked layer by layer on the support frame 44 under the action of the baffle 413. When the stack reaches the design elevation, the support cylinder 45 drives the support frame 44 to move down, and the stack of slabs on it will automatically fall with the support frame 44. The push cylinder 47 works to drive the push frame 48 to move to the right, conveying the stack of slabs suitable for passing through the bottom space of the baffle 413 to the right. When the push frame 48 conveys the re-stacked slabs to the right, it will first force the rotating swing arm 411 on it to rotate at an angle under the action of the pressure component 46. The deflection is caused by the connecting rod 410 to drive the integrated plates 49 to move closer to each other. During the process of the integrated plates 49 moving closer to each other, the rubber wheels 4122 installed on the rotating body 4121 will clamp and trim the four corners of the plate stack to ensure that the plate stack is neat. During the process of the pusher 48 conveying the plate stack to the right, the stacking conveyor belt 41 does not work, and the pusher 48 always replaces the support frame 44 to support the continuously conveyed slabs during the process of conveying the plate stack. When the right side of the pusher 48 is aligned with the right side of the slab, the support cylinder 45 will move the support plate 44 up to a position that is flush with the top of the pusher 48.

[0097] After the pallet stack is arranged, the push cylinder 47 drives the push frame 48 to move to the left and reset. The arranged pallet stack is then transported to the right by the stacking conveyor belt 41 and finally picked up by the robot arm for stacking.

[0098] Example 6, based on the above examples, makes the following improvements: the slab sorting line 30 includes a sorting conveyor belt 31 and a defective product conveyor belt 32, and the tail end of the defective product conveyor belt 32 is provided with a slab stacking line 40.

[0099] A method for sorting slabs in an automated sheet metal sorting system is as follows:

[0100] Step 1: Conveying whole stacks of slabs into single stacks of slabs

[0101] The whole stack of slabs is loaded onto the slab loading conveyor line 10 by a robot. The slab blanks are transferred from the whole stack to the single stack conveyor line 10. The slab pressing cylinder 19 on the mounting frame 13 drives the slab pressing plate 110 to press down on the single stack of slab blanks. The pressing point of the pressing plate 110 on the top of the slab blank is located on the side away from the moving frame 15. The end face clamping cylinder 17 drives the corresponding end face clamping plate 18 to clamp the end face of the single stack of slab blanks. The slab pressing cylinder 19 on the mounting plate 16 drives the slab pressing plate 110 to press down on the single stack of slab blanks. The pressing point of the pressing plate 110 on the top of the slab blank is located on the side away from the moving frame 15. The slab conveying cylinder 12 drives the moving frame 15 to convey the slab blanks onto the slab conveyor belt 21 along the horizontal guide rail 14.

[0102] Step 2: Conveying single stacks of slabs into single-panel slabs

[0103] The single stack of slabs conveyed by the slab stack feeding conveyor line 10 on the slab conveyor belt 21 is pressed and stabilized by the slab pressing cylinder 23 on the limiting frame 22 and the slab pressing plate 24. The pressing point of the slab pressing plate 24 at the top of the single stack of slabs is located on the side close to the limiting frame 22, and at this time the slabs are attached to the limiting plate 221. The end face clamping plate 18 presses the slab stack vertically at the first moment when the end of the stack is released. The slab conveyor belt 21 drives the bottom slabs to be conveyed one by one. During the conveying process, the slab pressing plate 24 ensures the stability of the stack. The single slabs conveyed one by one through the bottom gap of the limiting frame 22 are cleaned by the blowing air port on the cleaning pipe 222 to remove the debris on the surface of the single slabs.

[0104] Step 3: Sorting

[0105] The external CDD inspection mechanism, in conjunction with lighting, performs intelligent quality inspection on the slabs and sorts out those that do not meet the requirements. The slabs that do not meet the requirements are conveyed by the defective product conveyor belt 32, while the slabs that meet the requirements are conveyed by the sorting conveyor belt 31.

[0106] Step 4: Stacking and Consolidation

[0107] The slabs, which are continuously conveyed by the sorting conveyor belt 31, fall onto the support frame 44 under the action of the baffle 413. When they are stacked to a suitable thickness, the piston end of the support cylinder 45 drives the upper surface of the support frame 44 to move down to be flush with the bottom surface of the push frame 48. The piston end of the push cylinder 47 drives the push frame 48 to push the stacked slabs onto the stacking conveyor belt 41. During the pushing process, the swing arm 411 will come into contact with the pressure component 46, forcing the swing arm 411 to rotate. Through the connecting rod 410, the integrated plates 49 on both sides move towards the side closer to the push frame 48. At this time, the stacked slabs are already on the stacking conveyor belt 41. As the swing arm 411 continues to deflect, it drives the integrated plates 49 to move further towards the middle of the push frame 48. After the integrated rubber wheel 412 performs front-to-back and left-to-right straightening of the slabs, the push cylinder 47 drives the push frame 48 to reset, and the swing arm 411 is also reset synchronously by the torsion spring.

[0108] Step 5: Palletizing

[0109] The stacked pallets are then re-stacked by a robotic arm.

The board blanks are transferred from the whole stack to the single stack conveyor line (10). The board stack pressing cylinder (19) on the mounting frame (13) drives the board stack pressing plate (110) to press down the single stack of board blanks. The pressing point of the pressing plate (110) on the top of the board stack of board blanks is located on the side away from the moving frame (15).

Step 2: Conveying single stacks of slabs into single-panel slabs The single stack of slabs conveyed by the slab stack feeding conveyor line (10) on the slab conveyor belt (21) is pressed and stabilized by the slab pressing cylinder (23) on the limit frame (22) and the slab pressing plate (24). The pressing point of the slab pressing plate (24) at the top of the single stack of slabs is located on the side close to the limit frame (22), and at this time the slabs are attached to the limit plate (221). The end face clamping plate (18) presses the slab stack vertically at the first moment when the end of the stack is released.
