Description

Technical Field

[0001] This invention relates to the technical field of ceramic production, and more specifically, to a system and method for automatically identifying and processing waste blanks. Background Technology

[0002] In the glaze decoration stage of large-scale ceramic production, defects such as cracking and delamination may occur in the brick blanks after forming and transportation. If these waste blanks are not separated in time and continue to enter the downstream of the glaze line with normal brick blanks, multiple problems will occur: First, when the waste blanks enter the inkjet printer's conveyor channel, the irregular structure caused by surface cracks or delamination is prone to collision with the inkjet head, causing wear and blockage of the inkjet head and leading to equipment shutdown; Second, when the waste blanks enter the lifting and storage racks, they can cause confusion in the photoelectric sensors, resulting in chaotic operation of the lifting and storage racks, leading to blank jamming and blockage. Manual handling poses safety hazards and cannot guarantee production continuity. Currently, the industry relies on manual intervention to handle waste blanks. Dedicated operators are stationed next to the glaze line conveyor belt to visually identify waste blanks and manually remove them from the conveyor belt. This not only has the problem of inaccurate identification, but also requires operators to frequently reach above the running conveyor belt to pick up blanks, posing a safety hazard of hand injury from being caught in the belt. Summary of the Invention

[0003] The purpose of this invention is to provide a system and method for automatically identifying and processing waste blanks, so as to solve the technical problems of inaccurate identification and safety hazards in the manual identification and processing of waste blanks in the prior art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: On one hand, the present invention provides a system for automatically identifying and processing waste blanks, comprising at least: A conveying mechanism for conveying brick blanks includes a conveyor belt and conveyor rollers; A cracked brick blank sorting and identification mechanism is located above the conveyor belt and is used to detect cracked brick blanks with cracking defects being transported on the conveyor belt. A sandwich brick blank sorting and identification mechanism is located above the conveyor belt and downstream of the cracked brick blank sorting and identification mechanism, and is used to detect sandwich brick blanks with sandwich defects being transported on the conveyor belt. The waste brick processing mechanism is located above the conveying roller and downstream of the sandwich brick blank sorting and identification mechanism, and is used to crush cracked brick blanks and sandwich brick blanks.

[0005] According to the above-described automatic identification and processing system for waste bricks, the cracked brick sorting and identification mechanism includes: A first support frame is disposed across the conveyor belt; At least one first photoelectric sensor is provided on the first support frame and located above the conveyor belt. The first photoelectric sensor is used to detect cracked brick blanks present on the conveyor belt.

[0006] According to the above-described automatic identification and processing system for waste bricks, the cracked brick sorting and identification mechanism includes multiple first photoelectric sensors, and the multiple first photoelectric sensors are arranged at equal intervals.

[0007] According to the above-described automatic identification and processing system for waste bricks, the sandwich brick sorting and identification mechanism includes: A second support frame is provided across the conveyor belt; A limiting baffle is suspended on the second support frame by a connecting rope, and the limiting baffle spans the conveyor belt and has a preset distance between it and the upper surface of the conveyor belt; At least one second photoelectric sensor is connected to the second support frame and is located on the side of the limiting baffle away from the conveyor belt conveying direction. The second photoelectric sensor is used to detect the offset of the limiting baffle to determine the presence of sandwich brick blanks on the conveyor belt.

[0008] According to the above-described automatic identification and processing system for waste bricks, the sandwich brick sorting and identification mechanism includes at least two second photoelectric sensors, and the second photoelectric sensors are provided at least at both ends of the limiting baffle.

[0009] According to the above-described automatic identification and processing system for waste blanks, the waste blank processing mechanism includes: A third support frame is provided across the conveying roller bar, which comprises multiple roller bars spaced apart, with gaps between adjacent roller bars. A crushing and processing mechanism is provided on a third support frame. The crushing and processing mechanism is used to crush waste blanks, and the crushed waste blanks are discharged through the gap.

[0010] According to the above-described automatic identification and processing system for waste blanks, the crushing and processing mechanism includes: A lifting cylinder, which is connected to the third support frame; A spiked club, wherein the spiked club is located at the output end of the lifting cylinder and connected to the lifting cylinder; A mace-shaped rotating gearbox is connected to the mace to drive the mace to rotate.

[0011] According to the above-described automatic identification and processing system for waste blanks, the system further includes a waste blank recycling mechanism, which includes a waste blank conveyor belt and a recycling bin. The waste blank conveyor belt is located below the waste blank processing mechanism and transports the collected waste blanks to the recycling bin.

[0012] On the other hand, the present invention also provides a method for automatically identifying and processing scrap blanks, applied to the aforementioned system for automatically identifying and processing scrap blanks, comprising: Obtain detection data from at least one of the cracked brick blank sorting and identification mechanism and the sandwich brick blank sorting and identification mechanism; Based on the detection data, the waste blank processing mechanism is controlled to crush the waste blanks transported by the conveyor belt at the conveyor rollers. The waste blank recycling mechanism is controlled to collect the crushed waste blanks.

[0013] According to the above-described method for automatically identifying and processing waste blanks, the detection data of both the cracked brick blank sorting and identification mechanism and the sandwich brick blank sorting and identification mechanism are obtained simultaneously. Based on the order in which cracked brick blanks and sandwich brick blanks arrive at the waste blank processing unit, the waste blank processing unit is controlled to crush them sequentially.

[0014] The beneficial effects of the automatic identification and processing system and method for waste blanks provided by this invention are at least as follows: The system and method for automatically identifying and processing waste bricks provided in this embodiment, by setting up cracked brick sorting and identification mechanisms and sandwich brick sorting and identification mechanisms on the conveying mechanism, identifies the waste bricks conveyed on the conveying mechanism, then sorts out the waste bricks and conveys them to the waste brick processing mechanism, which crushes the waste bricks and then recycles them. This not only improves the accuracy of waste brick identification (reaching over 99.5%), but also reduces the probability of waste bricks flowing into downstream processes to less than 0.5%, significantly reducing the failure frequency of inkjet printers and lifting storage racks, effectively ensuring production continuity, but also avoids and eliminates the safety hazards of manual waste brick handling. The system requires no manual intervention, saving labor costs. Simultaneously, while the system is processing waste bricks, the conveying mechanism remains running, and the transmission of normal bricks does not need to be paused, avoiding the conveying interruption problem during manual brick picking and improving production efficiency. As can be seen, the present invention installs and constructs a "identification-sorting-recycling-transporting" coordinated automatic identification and processing system for waste blanks during the glaze production process. Without affecting the normal brick blank transportation, it realizes the automatic separation and processing of waste blanks, solving the problems of low efficiency, poor safety, and interference with the normal transportation process of manual sorting.

Detailed Implementation

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it may be directly or indirectly located on that other component. When a component is referred to as "connected to" another component, it may be directly or indirectly connected to that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate orientations or positions based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "A plurality" means two or more, unless otherwise explicitly defined.

[0020] Please see Figure 1 and Figure 2 This embodiment provides an automatic identification and processing system 100 for waste bricks, which includes at least a conveying mechanism 10, a cracked brick sorting and identification mechanism 20, a sandwich brick sorting and identification mechanism 30, and a waste brick processing mechanism 40. The conveying mechanism 10, the cracked brick sorting and identification mechanism 20, the sandwich brick sorting and identification mechanism 30, and the waste brick processing mechanism 40 are all electrically connected to the controller via cables to form a closed-loop control automatic identification and processing system 100 for waste bricks.

[0021] The conveying mechanism 10 is used to convey brick blanks and includes a conveyor belt 11 and a conveyor roller 12, which are located on the same conveying line.

[0022] A cracked brick blank sorting and identification mechanism 20 is located above the conveyor belt 11 and is used to detect cracked brick blanks 200 with cracking defects transported on the conveyor belt 11. A sandwich brick blank sorting and identification mechanism 30 is located above the conveyor belt 11 and downstream of the cracked brick blank sorting and identification mechanism 20, and is used to detect sandwich brick blanks 300 with sandwiching defects transported on the conveyor belt 11. A waste brick processing mechanism 40 is located above the conveyor roller 12 and downstream of the sandwich brick blank sorting and identification mechanism 30, and is used to crush the cracked brick blanks 200 and the sandwich brick blanks 300. Optionally, the distance between the cracked brick blank sorting and identification mechanism 20 and the downstream sandwich brick blank sorting and identification mechanism 30 is 0.8m to 1.2m, and the distance between the sandwich brick blank sorting and identification mechanism 30 and the downstream waste brick processing mechanism 40 is 1.8m to 2.2m.

[0023] The overall working principle of the automatic identification and processing waste blank system 100 provided in this embodiment is as follows: The automatic identification and processing system 100 provided in this embodiment is based on a controller to realize the signal linkage of various mechanisms. The system includes a normal conveying mode and a waste processing mode. The brick blanks are continuously placed on the conveying mechanism 10 and conveyed sequentially in the conveying direction. They are sequentially detected by two types of identification mechanisms: the cracked brick blank sorting and identification mechanism 20 and the sandwich brick blank sorting and identification mechanism 30. Normal brick blanks continue to flow along the conveying mechanism 10 to the subsequent process, while waste blanks trigger the action of the waste processing mechanism 40, are separated and processed and recycled, and finally realize the automatic sorting of waste blanks and normal brick blanks. The two modes can be switched seamlessly, and the operation of the conveying mechanism 10 is not interrupted throughout the process.

[0024] Normal delivery mode: When no defects are detected in the cracked brick blank sorting and identification mechanism 20 and the sandwich brick blank sorting and identification mechanism 30, the brick blank is considered a normal brick blank. At this time, the system is in normal conveying mode. The normal brick blank continues to be conveyed in the conveying direction and passes through the waste blank processing mechanism 40. The waste blank processing mechanism 40 does not break the normal brick blank. The normal brick blank simply passes through the waste blank processing mechanism 40 and continues to flow along the conveying direction of the conveying mechanism 10 to the subsequent glazing, inkjet decoration and other processes.

[0025] Scrap blank processing mode: When a brick blank is identified as a cracked brick blank 200 at the cracked brick blank sorting and identification mechanism 20, or when a brick blank is identified as a sandwich brick blank 300 at the sandwich brick blank sorting and identification mechanism 30, or when both cracked brick blank 200 and sandwich brick blank 300 are identified at the cracked brick blank sorting and identification mechanism 20 and the sandwich brick blank sorting and identification mechanism 30, the waste brick processing mechanism 40 needs to be activated in all three cases. When the waste brick enters the waste brick processing mechanism 40, it is crushed and then recycled.

[0026] The beneficial effects of the automatic identification and processing waste blank system 100 provided in this embodiment are as follows: The automatic waste brick identification and processing system 100 provided in this embodiment uses a cracked brick sorting and identification mechanism 20 and a sandwich brick sorting and identification mechanism 30 on the conveying mechanism 10 to identify waste bricks conveyed on the conveying mechanism 10. The waste bricks are then sorted out and conveyed to the waste brick processing mechanism 40, where they are crushed and recycled. This system not only improves the accuracy of waste brick identification (reaching over 99.5%), but also reduces the probability of waste bricks flowing into downstream processes to less than 0.5%, significantly reducing the failure frequency of inkjet printers and lifting storage racks, effectively ensuring production continuity, but also avoids and eliminates the safety hazards associated with manual waste brick handling. The system requires no manual intervention, saving labor costs. Furthermore, while the system is processing waste bricks, the conveying mechanism 10 remains operational, eliminating the need to pause the transmission of normal bricks and avoiding the interruption problems associated with manual brick picking, thus improving production efficiency. As can be seen, the present invention installs and constructs a "identification-sorting-recycling-transporting" coordinated automatic identification and processing system 100 for waste blanks during the glaze production process. Without affecting the normal brick blank transportation, it realizes the automatic separation and processing of waste blanks, solving the problems of low efficiency, poor safety, and interference with the normal transportation process of manual sorting.

[0027] In one embodiment, see Figure 3 The cracked brick blank sorting and identification mechanism 20 includes a first support frame 210 and at least one first photoelectric sensor 220. The first support frame 210 is arranged across the conveyor belt 11; the first photoelectric sensor 220 is disposed on the first support frame 210 and located above the conveyor belt 11. The first photoelectric sensor 220 is used to detect cracked brick blanks 200 present on the conveyor belt 11. Since there is a first set distance (e.g., 10mm) between the upper surface of the brick blank and the first photoelectric sensor 220, the first photoelectric sensor 220 is used to detect whether the distance between the upper surface of the brick blank and the first photoelectric sensor 220 is within the first set distance (e.g., 10mm). If the first photoelectric sensor continuously senses a signal within the first set distance, it indicates that it is a normal brick blank; if it exceeds the first set distance and the first photoelectric sensor shows an intermittent signal, it indicates that it is a cracked brick blank. By setting the first photoelectric sensor 220, it is possible to determine whether it is a cracked brick blank 200. The determination method is simple and highly accurate, with an accuracy rate of over 99.5%. If the brick blank 200 is cracked, the waste blank processing mechanism 40 is activated to crush the cracked brick blank 200 conveyed by the conveyor belt 11. The cracked brick blank sorting and identification mechanism 20 has a simple overall structure, is easy to manufacture, and is easy to install.

[0028] In one embodiment, please continue reading Figure 3The cracked brick blank sorting and identification mechanism 20 includes a plurality of first photoelectric sensors 220, which are arranged at equal intervals. The multiple first photoelectric sensors 220 are arranged at intervals to ensure the comprehensiveness and accuracy of the detection by the first photoelectric sensors 220, thereby improving the accuracy of identifying cracked brick blanks 200.

[0029] In one embodiment, the cracked brick blank sorting and identification mechanism 20 includes 2 to 8 first photoelectric sensors 220, and correspondingly, the number of first photoelectric sensor connectors 230 is also 2 to 8. Optionally, the cracked brick blank sorting and identification mechanism 20 includes 5 first photoelectric sensors 220 and 5 first photoelectric sensor connectors 230, with the 5 first photoelectric sensors 220 and 5 first photoelectric sensor connectors 230 equally spaced on the first support frame 210. Optionally, the number and position of the first photoelectric sensors 220 are not limited to the above-described cases and can be other cases, which are not limited here.

[0030] In one embodiment, the first support frame 210 includes a first support beam 211 and two first support columns 212 disposed at both ends of the first support beam 211. At least one first photoelectric sensor connector 230 is provided on the first support beam 211, and the first photoelectric sensor 220 is mounted on the first photoelectric sensor connector 230. The structure of the first support frame 210 is simple, facilitating the installation of the first photoelectric sensor 220 via the first photoelectric sensor connector 230.

[0031] Optionally, the first photoelectric sensor connector 230 is L-shaped, including a first connecting section 231 and a second connecting section 232. The first connecting section 231 and the second connecting section 232 are connected to form an L-shape. The first connecting section 231 is connected to the first support beam 211. The first photoelectric sensor 220 is installed on the second connecting section 232, so that the first photoelectric sensor 220 faces the brick blank, which is convenient for detecting the brick blank.

[0032] In one embodiment, see Figure 4 The sandwich brick blank sorting and identification mechanism 30 includes a second support frame 310, a limiting baffle 320, and at least one second photoelectric sensor 330.

[0033] The second support frame 310 is arranged across the conveyor belt 11. The limiting baffle 320 is suspended on the second support frame 310 by a connecting rope 340. The limiting baffle 320 spans the conveyor belt 11 and has a preset distance between it and the upper surface of the conveyor belt 11. The second photoelectric sensor 330 is connected to the second support frame 310 and is located on the side of the limiting baffle 320 away from the conveying direction of the conveyor belt 11. The second photoelectric sensor 330 is used to detect the offset of the limiting baffle 320 to determine the presence of sandwich brick blanks 300 on the conveyor belt 11.

[0034] If the brick blank is a sandwich brick blank 300, then the thickness of the sandwich brick blank 300 is greater than the thickness of a normal brick blank. When the conveyor belt 11 is conveying a sandwich brick blank 300, when the sandwich brick blank 300 passes through the sandwich brick blank sorting and identification mechanism 30, because there is a preset distance between the lower surface of the limiting baffle 320 and the upper surface of the conveyor belt 11, which is the distance that a normal brick blank can pass through, when the sandwich brick blank 300 passes through, because the limiting baffle 320 is connected to the second support frame 310 by the connecting rope 340, it can shake, and the thickness increases. The sandwich brick blank 300 will cause the limiting baffle 320 to sway and deviate in the conveying direction of the conveyor belt 11. Since there is a second set distance (e.g., 2mm) between the limiting baffle 320 and the second photoelectric sensor 330, the second photoelectric sensor 330 is used to detect whether the distance between the limiting baffle 320 and the second photoelectric sensor 330 is within the second set distance. If it is within the second set distance, the second photoelectric sensor continuously senses a signal, indicating that it is a normal brick blank. If it exceeds the second set distance, the second photoelectric sensor shows an intermittent signal, indicating that it is a sandwich brick blank. When the controller determines that it is a sandwich brick blank 300, it controls the start of the waste blank processing mechanism 40 to break up the sandwich brick blank 300 transmitted from the conveyor belt 11. The above-mentioned sandwich brick blank sorting and identification mechanism 30, which uses the second photoelectric sensor 330 to detect whether the limiting baffle 320 is deviated to determine whether the brick blank is a sandwich brick blank 300, has a simple judgment method and high accuracy, with an accuracy rate of over 99.5%.

[0035] In one embodiment, please continue reading Figure 4 The sandwich brick blank sorting and identification mechanism 30 includes at least two second photoelectric sensors 330, with the second photoelectric sensors 330 located at at least both ends of the limiting baffle 320. The presence of second photoelectric sensors 330 at at least both ends of the limiting baffle 320 further ensures the accuracy of the second photoelectric sensors 330 in detecting whether the limiting baffle 320 has shifted.

[0036] In one embodiment, please continue reading Figure 4 The preset distance is the sum of the normal brick thickness and the reserved gap. The reserved gap is the distance from the upper surface of the normal brick to the lower surface of the limiting baffle 320. The reserved gap is no more than 1mm. The setting of this gap ensures that the normal brick will not hit the limiting baffle 320 and trigger an alarm when it passes through.

[0037] In one embodiment, the structure of the second support frame 310 is the same as that of the first support frame 210, and will not be described again here. The second photoelectric sensor 330 is connected to the second support frame 310 through the second photoelectric sensor connector 350. The second photoelectric sensor connector 350 is I-shaped, and the second photoelectric sensor 330 and the limiting baffle 320 are at the same horizontal height.

[0038] In one embodiment, see Figure 5 The waste blank processing mechanism 40 includes a third support frame 410 and a crushing processing mechanism 420. The third support frame 410 is arranged across the conveying roller 12, which comprises a plurality of rollers 121 spaced apart, with gaps 122 between adjacent rollers 121. The structure of the third support frame 410 is the same as that of the first support frame 210, and will not be described again here. The crushing processing mechanism 420 is mounted on the third support frame 410 and is used to crush the waste blank. The crushed waste blank is discharged through the gaps 122.

[0039] When the crushing and processing mechanism 420 is activated to crush the waste bricks, the rollers 121 gradually feed the waste bricks to the waste brick processing mechanism 40 for crushing. The crushed waste bricks fall from the gaps 122 between the rollers 121. It can be seen that the setting of the conveying rollers 12 not only ensures the normal transmission of the bricks, but also facilitates the discharge of the crushed bricks from the gaps 122 between the rollers 121.

[0040] In one embodiment, please continue reading Figure 5 The crushing mechanism 420 includes a lifting cylinder 421, a spiked club 422, and a rotating gearbox 423. The lifting cylinder 421 is connected to the third support frame 410. The spiked club 422 is located at the output end of the lifting cylinder 421 and connected to it. The rotating gearbox 423 is connected to the spiked club 422 to drive its rotation. Optionally, the third support frame 410 has two lifting cylinders 421, and both ends of the spiked club 422 are connected to the output ends of the two lifting cylinders 421 respectively, ensuring smooth lifting and lowering of the spiked club 422.

[0041] When it is necessary to crush the waste blank, the controller controls the start lifting cylinder 421 to move from the high position to the low position, and controls the rotating gearbox 423 to drive the spike 422 to rotate, thereby crushing the waste blank. After crushing is completed, the controller controls the rotating gearbox 423 to stop rotating and controls the lifting cylinder 421 to return to the high position. The crushing mechanism 420 has a simple structure and good crushing effect.

[0042] In one embodiment, please continue reading Figure 5The automatic waste blank identification and processing system 100 further includes a waste blank recycling mechanism 50, which includes a waste blank conveyor belt 51 and a recycling bin 52. The waste blank conveyor belt 51 is located below the waste blank processing mechanism 40, and it transports the collected waste blanks to the recycling bin 52. When the waste blank processing mechanism 40 is started, the waste blank recycling mechanism 50 is also started, that is, the waste blank conveyor belt 51 is activated. The waste blanks broken by the waste blank processing mechanism 40 fall onto the waste blank conveyor belt 51 located below it, and the waste blank conveyor belt 51 transports the waste blanks into the recycling bin 52 for collection.

[0043] The detailed working process of the automatic identification and processing system 100 for waste blanks provided in this embodiment is as follows: Normal delivery mode: When the brick blanks pass through the first photoelectric sensor 220 and the second photoelectric sensor 330, no defects are detected or identified. That is, the cracked brick blank sorting and identification mechanism 20 outputs a continuous high-level signal, and the sandwich brick blank sorting and identification mechanism 30 outputs a stable low-level signal. The controller does not receive any waste blank identification signal. At this time, the system is in normal conveying mode, the conveyed brick blanks are normal brick blanks, and the conveying mechanism 10 maintains a uniform speed. Normal brick blanks sequentially pass through the cracked brick blank sorting and identification mechanism 20, the sandwich brick blank sorting and identification mechanism 30, the waste brick blank processing mechanism 40, and the waste brick blank recycling mechanism 50. The controller controls the lifting cylinder 421 and the rotating gearbox 423 in the waste brick blank processing mechanism 40 and the waste brick blank conveyor belt 51 in the waste brick blank recycling mechanism 50 to be in standby mode and not to interfere with the conveying process of normal brick blanks. When the conveying mechanism 10 continues to convey normal brick blanks in the conveying direction and passes through the waste brick blank processing mechanism 40, the waste brick blank processing mechanism 40 will not process the normal brick blanks. After passing through the waste brick blank processing mechanism 40, the normal brick blanks continue to flow along the conveying mechanism 10 to the subsequent glazing, inkjet decoration and other processes.

[0044] Scrap blank processing mode: The first photoelectric sensor 220 of the cracked brick blank sorting and identification mechanism 20 detects the brick blanks conveyed on the conveying mechanism 10. Since there is a first set distance (e.g., 10mm) between the upper surface of the brick blank and the first photoelectric sensor 220, the first photoelectric sensor 220 is used to detect whether the distance between the upper surface of the brick blank and the first photoelectric sensor 220 is within the first set distance (e.g., 10mm). If the first photoelectric sensor continuously senses a signal within the first set distance, it indicates that the brick blank is normal. If the distance exceeds the first set distance and the first photoelectric sensor shows an intermittent signal, it indicates that the brick blank is cracked. The controller calculates the time it takes for the cracked brick blank 200 to reach the spike bar 422. When the cracked brick blank 200 reaches below the spike bar 422, the controller's lifting cylinder 421 lowers the spike bar 422 to a low position. It also controls the rotating gearbox 423 to rotate the spike bar 422 to crush the waste brick. At the same time, it controls the waste brick conveyor belt 51 to start conveying the crushed waste brick and transfer it to the recycling bin 52 for collection. After the cracked brick blank 200 is crushed, the controller controls the lifting cylinder 421 to drive the spike bar 422 back to a high position, the waste brick conveyor belt 51 stops moving, and the system returns to normal mode.

[0045] The second photoelectric sensor 330 of the sandwich brick blank sorting and identification mechanism 30 detects whether the limiting baffle 320 is deviated. Since there is a second set distance (e.g., 2mm) between the limiting baffle 320 and the second photoelectric sensor 330, the second photoelectric sensor 330 is used to detect whether the distance between the limiting baffle 320 and the second photoelectric sensor 330 is within the second set distance. If it is within the second set distance, the second photoelectric sensor continuously senses a signal, which indicates that it is a normal brick blank. If it exceeds the second set distance, the second photoelectric sensor shows an intermittent signal, which indicates that it is a sandwich brick blank. The controller calculates the time it takes for the sandwich brick blank 300 to reach the spike bar 422. When the sandwich brick blank 300 reaches below the spike bar 422, the controller lifts the spike bar 422 to a low position and controls the rotating gearbox 423 to rotate the spike bar 422 to crush the waste brick. At the same time, the controller controls the waste brick conveyor belt 51 to start conveying the crushed waste brick and transfer it to the recycling bin 52 for collection. When the sandwich brick blank 300 is crushed, the controller lifts the spike bar 422 to return to a high position, the waste brick conveyor belt 51 stops moving, and the system returns to normal mode.

[0046] If cracked brick blank 200 and sandwich brick blank 300 are detected simultaneously within the same time period (interval less than 0.3 seconds), the controller will trigger the waste blank processing mechanism and the waste blank recycling mechanism in sequence according to the order in which they arrive at the spiked club 422. The waste blank that arrives first will be processed first, and then the waste blank that arrives later will be processed, ensuring that both types of waste blanks are separated, crushed and recycled, without affecting the normal brick blank conveying during the period.

[0047] Please see Figure 6This embodiment also provides a method for automatically identifying and processing scrap blanks, applied to the aforementioned system for automatically identifying and processing scrap blanks, including: S100: Obtain detection data from at least one of the cracked brick blank sorting and identification mechanism 20 and the sandwich brick blank sorting and identification mechanism 30.

[0048] In the cracked brick blank sorting and identification mechanism 20, the first photoelectric sensor 220 is used to detect whether the distance between the upper surface of the brick blank and the first photoelectric sensor 220 is within a first set distance (e.g., 10mm). If the first photoelectric sensor continuously senses a signal within the first set distance, it indicates that the brick blank is normal. If the distance exceeds the first set distance and the first photoelectric sensor shows a signal interruption, it indicates that the brick blank is cracked.

[0049] In the sandwich brick blank sorting and identification mechanism 30, the second photoelectric sensor 330 is used to detect whether the distance between the limiting baffle 320 and the second photoelectric sensor 330 is within a second set distance (e.g., 2mm). If the second photoelectric sensor continuously senses a signal within the second set distance, it indicates that the brick blank is normal. If the distance exceeds the second set distance and the signal of the second photoelectric sensor is interrupted, it indicates that the brick blank is sandwich brick blank.

[0050] S200. Based on the detection data, the waste blank processing mechanism 40 is controlled to crush the waste blanks transported from the conveyor belt 11 at the conveyor roller 12. When the detection data of either the cracked brick blank sorting and identification mechanism 20 or the sandwich brick blank sorting and identification mechanism 30 is detected, the spike bar 422 of the waste blank processing mechanism 40 is controlled to crush the transported waste blanks.

[0051] S300, the waste blank recycling mechanism 50 is controlled to collect the crushed waste blanks. The waste blank conveyor belt 51 of the waste blank recycling mechanism 50 is set below the conveyor roller 12 to receive the crushed waste blanks and control the transport of the crushed waste blanks to the recycling bin 52.

[0052] In one embodiment, detection data from both the cracked brick blank sorting and identification mechanism 20 and the sandwich brick blank sorting and identification mechanism 30 are acquired simultaneously. The detection data from both mechanisms are acquired within the same time period, which is defined as an interval of less than 0.3 seconds.

[0053] Based on the order in which cracked brick blanks 200 and sandwich brick blanks 300 arrive at the waste blank processing mechanism 40, the waste blank processing mechanism 40 is controlled to crush them sequentially. The waste blanks that arrive first are processed first, followed by the waste blanks that arrive later, ensuring that both types of waste blanks are separated, crushed, and recycled without affecting the normal conveying of brick blanks during the process.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
