Description

Technical Field

[0001] This utility model relates to the field of refractory brick thickness detection, specifically a refractory brick thickness measurement system after demolding. Background Technology

[0002] In modern refractory brick production, measurement and testing are essential, especially thickness measurement. Measurements must be taken after molding and demolding, and before stacking after kiln exit. The accuracy of thickness directly affects the thermal conductivity, mechanical strength, and service life of the refractory bricks. If the thickness does not meet standards, it may lead to uneven thermal expansion of the refractory bricks under high-temperature environments, thus affecting the overall structural stability of the furnace. While the mold cavity dimensions remain constant, the molding process, based on factors such as the amount of filler and the molding process, can cause inaccurate thickness measurements. Therefore, measuring the thickness after demolding is a crucial step in promptly reflecting production status, identifying problems, and rejecting defective products.

[0003] In existing production lines, combined with automated production and conveying processes, thickness detection is typically performed using visual recognition or sensors, both requiring individual measurement. Visual measurement necessitates capturing, recording, and identifying images of each brick, resulting in massive amounts of data. This not only demands high-performance storage but also involves complex processing and significant costs. Sensor-based detection methods, on the other hand, require sorting and locating each brick to obtain data, which is time-consuming and complex. Utility Model Content

[0004] The purpose of this invention is to provide a thickness measurement system for refractory bricks after demolding, which can batch detect the thickness data of brick blanks, thereby timely screening of production problems and reducing detection costs.

[0005] To achieve the above objectives, this utility model employs the following technical solution: A thickness measurement system for refractory bricks after demolding includes a mounting base fixedly disposed relative to the production area. One end of the mounting base is hinged to a sorting plate, which has a swing stroke that switches between a horizontal state and an upward tilt. A material rack is disposed above the sorting plate, and the material rack has a linear reciprocating stroke relative to the length of the sorting plate. One end of the material rack is provided with a vertical end baffle, and a side baffle is provided on one side of the long side of the material rack that is connected to the end baffle. A distance measuring sensor is disposed at the end away from the end baffle.

[0006] One end of the mounting base is provided with a mounting shaft fixed thereto. The mounting shaft is arranged parallel to the width direction of the mounting base. One end of the sorting table is provided with a downwardly extending folding plate. The folding plate is fixed perpendicularly to the sorting table. The bottom side of the folding plate is rotatably connected to the mounting shaft. The middle part of the mounting base is provided with a lower hinge seat. An upper hinge seat is fixed on the bottom surface of the sorting table. A sorting cylinder is hinged to the lower hinge seat. The top end of the sorting cylinder is provided with a sorting cylinder rod that telescopically cooperates with it. The top end of the sorting cylinder rod is hinged to the upper hinge seat.

[0007] Two rows of slide rails are fixed side by side on the sorting table. A slider is slidably fitted on the slide rail. The top surface of the slider is fixed to the bottom of the material rack. A stroke cylinder is fixed on the side end plate. One end of the stroke cylinder is provided with a stroke cylinder rod that cooperates with it. The end of the stroke cylinder rod is fixed to the opposite end baffle.

[0008] The material rack includes a base plate and an inclined plate. The top of the slider is fixed to the bottom surface of the base plate, and the inclined plate is fixed above the base plate. The top surface of the inclined plate is provided with an inclined surface, which slopes downward from the side away from the side baffle to the side close to the side baffle.

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

Unless otherwise specified, the experimental methods and detection methods used in the following embodiments are all conventional experimental methods and detection methods already available in the prior art. Example

[0020] In production, thickness data is primarily used to eliminate obviously defective workpieces. Furthermore, since modern production lines are automated, any problems with the feeding or molding equipment that aren't detected promptly can lead to batch losses. Therefore, post-demolding inspection is also for identifying issues. This process of individually sorting and measuring each piece places a significant burden on equipment configuration and data processing.

[0021] This solution is primarily designed to achieve batch testing and eliminate problematic batches. Its main structure, following the material conveying sequence after refractory brick demolding, includes: Conveying module, batch testing module.

[0022] The conveying module can use common existing conveying equipment, such as belt conveyor 1 or double belt conveyor, in conjunction with the upstream automated pressing equipment to transfer the brick blanks. Not limited to this example, the system can also directly set the batch detection module at the material discharge side of the existing production line's free conveyor for coordinated use.

[0023] The batch inspection module is an important improvement in this system, which can realize multiple functions such as arranging brick blanks, batch checking thickness, and material handling for mechanical grippers.

[0024] The batch detection module includes: sensor 16, mounting base 2, sorting platform 4, material rack, sorting cylinder 14, and stroke cylinder 15; The mounting base 2 is fixedly installed in the production area, and the mounting base 2 is used to support the entire module.

[0025] The mounting base 2 is a rectangular cast iron base, which can be fixed with fasteners or have a worktable added to the bottom for leveling with the conveying module.

[0026] One end of the mounting base 2 is provided with a mounting shaft 3 fixed thereto. The mounting shaft 3 is arranged side by side with respect to the width direction of the mounting base 2. The sorting table 4 is a rectangular metal plate. One end of the sorting table 4 is provided with a downwardly extending folding plate 5. The folding plate 5 is vertically fixed relative to the sorting table 4. The bottom side of the folding plate 5 is provided with a sleeve 6 that is sleeved and rotatably engaged with the mounting shaft 3.

[0027] The mounting base 2 has a lower hinge seat in the middle. The bottom end of the sorting cylinder 14 is hinged to the lower hinge seat. An upper hinge seat is fixed on the bottom surface of the sorting platform 4. The top end of the sorting cylinder 14 is provided with a sorting cylinder rod that is telescopically coordinated with it. The top end of the sorting cylinder rod is hinged to the upper hinge seat.

[0028] Based on the above structure, the swing angle of the sorting table 4 can be controlled, so that the sorting table 4 can swing between a horizontal state and an upward tilted state.

[0029] Two rows of slide rails 7 are fixed side by side on the sorting platform 4. Slider blocks 8 are slidably fitted on the slide rails 7, and the top surface of the slider blocks 8 is fixed to the bottom of the material rack. Specifically, the material rack includes a base plate 9, an inclined plate 10, a vertical plate 11, an end baffle 12, and a side baffle 13.

[0030] The top of the slider 8 is fixed to the bottom of the base plate 9.

[0031] The base plate 9 is rectangular, and the length direction of the base plate 9 corresponds to the length direction of the sorting table 4. The bottom side of the end baffle 12 is vertically fixed to one side of the wide side of the base plate 9. The end baffle 12 is set close to the mounting shaft 3. The bottom side of the side baffle 13 is vertically fixed to one side of the long side of the base plate 9. The adjacent sides of the end baffle 12 of the side baffle 13 are vertically connected.

[0032] The end baffle 12 and the side baffle 13 form a semi-enclosed structure for the bottom plate 9. In use, the side without the side baffle 13 is positioned close to the feeding end of the conveying module to receive the brick blank.

[0033] The inclined plate 10 is fixed above the base plate 9. The top surface of the inclined plate 10 has an inclined surface, which slopes downward from the side away from the side baffle 13 to the side closer to the side baffle 13. This makes the side closer to the conveyor module higher. After the brick blank is picked up, it slides down due to the speed of the brick blank on the conveyor belt, so that the brick blank is close to the side baffle 13. The higher side of the inclined surface is slightly lower than the top surface of the belt conveyor 1, thus facilitating the smooth picking up of the brick blank. Not limited to this example, the inclined plate 10 can also be omitted. Under the conveying inertia of the conveyor belt, the brick blank will automatically move towards the side baffle 13, and whether the movement is neat or not has no impact on the thickness detection.

[0034] A vertical plate 11 is fixed on the inner end face of the end baffle 12. The vertical plate 11 is set perpendicularly to the inclined plate 10 or the bottom plate 9. The vertical plate 11 is set in the middle of the end baffle 12 to block the brick blank. There is a certain space between the vertical plate 11 and the side baffle 13 to allow space for the robot arm to grasp.

[0035] A strip plate is provided on the top side of the side baffle 13 away from the end baffle 12 and fixed thereto. The bottom side of the strip plate is fixedly welded to the top side of the side baffle 13. The stroke cylinder 15 is fixedly installed on the strip plate. The end of the stroke cylinder 15 near the end baffle 12 is provided with a stroke cylinder rod that is telescopically coordinated with it. The end of the material rack is fixed relative to the end baffle 12 to realize the driving and position control of the reciprocating stroke of the material rack, so that the material rack adjusts its position as the brick blanks are piled up, making room for the empty space.

[0036] The sensor 16 is located at the end furthest from the end plate and can be fixed to the sorting table 4. The sensor 16 can be an infrared or laser sensor, used to measure the distance to the nearest brick. As the bricks falling on the inclined plate 10 are pushed by the conveyor belt at its own speed, they fall onto the side baffle 13 in a row due to the inclined surface. Then, with the tilting motion of the sorting table 4, the row of bricks accumulates towards the vertical plate 11, resulting in a neat row of bricks with no gaps between adjacent bricks. This system detects bricks in groups of 10, comparing the measured distance data with the standard distance from 10 bricks to the sensor 16. If the data difference exceeds a threshold, an alarm is triggered and timely feedback is provided. This screening method uses batch measurement, making it more efficient and greatly simplifying the algorithm and reducing storage pressure. It also quickly reflects production problems. Furthermore, by sorting the bricks, it replaces the sorting step before the robotic arm grabs the bricks from the conveyor belt, without adding extra steps or slowing down or hindering the conveyor rhythm.

[0037] The system works as follows: The brick blanks are conveyed one by one on the belt conveyor and fall from the discharge end; The batch detection module is located at the material dropping end. The top side of the inclined surface is set close to the material dropping end of the belt conveyor. The initial position is that the side of the inclined plate 10 near the end baffle 12 is aligned with the material dropping end. As the brick blanks are pushed onto the inclined plate 10, the material rack moves horizontally towards the end baffle 12, so that the brick blanks are arranged in multiple loose and gapped rows on the inclined plate 10. The brick blanks are piled on the inclined plate 10 and then on the side baffle 13. After accumulating 10 brick blanks, the conveyor belt stops and the sorting table 4 is tilted so that the brick blanks are piled up on the vertical plate 11 without gaps.

[0038] Once sensor 16 is activated to acquire distance data once, and the error is determined to be small, the robot or manual transfer of the brick blanks in this group is performed, and the table 4 and material rack are reset to start receiving brick blanks again.

[0039] This system enables batch detection of brick blank thickness, quickly screening for production problems. When there are problems with molding or feeding, they will be displayed on the processed brick blanks. Problems can be quickly identified by screening them in groups without adding steps, leaving brick blanks unused, or requiring brick blanks to be placed at multiple angles. This greatly reduces the pressure on data processing, resulting in timely response, improved efficiency, and reduced costs.
