Description

Technical Field

[0001] This invention relates to the field of measuring devices for gypsum board, and specifically to a self-braking dual detection system and method for the vertical edge angle of gypsum board. Background Technology

[0002] During the solidification and molding process of gypsum board on the conveyor, the fluctuations of gypsum slurry and paper can cause the two vertical edges of the gypsum board on both sides of the conveying direction to tilt. This results in the edge parameters of the molded gypsum board not meeting the specifications, affecting its normal use. The right angle of the board edge is an important indicator for measuring the quality of gypsum board.

[0003] To monitor the angle of the gypsum board edges in real time, production typically relies on manual judgment or laser sensor scanning to determine whether the vertical edge straightness of the gypsum board is up to standard. Manual adjustment of the vertical edge straightness is also necessary. However, manual judgment is prone to errors and cannot detect minute angle tilts. In addition, laser sensors can only detect the tilt of the vertical edge of the gypsum board. Based on the detection results, measures are taken to correct the parameters in the gypsum board forming process in a timely manner, so that the gypsum boards produced subsequently all meet the vertical edge standard.

[0004] However, in existing technologies, once gypsum boards with tilted vertical edges are detected as having vertical edge defects, the only solution is to scrap the boards. The laser sensor's angle detection over a long period of time may have a certain error. Adjusting the molding process parameters solely based on the laser sensor's measurement results may lead to incorrect parameters being adjusted when the laser sensor malfunctions. This results in scrapping qualified boards with acceptable vertical edge parameters, and subsequent boards having non-compliant vertical edges, causing a batch of unqualified boards to be rejected. Summary of the Invention

[0005] To address these issues, this invention provides a self-braking dual detection system and method for the vertical edge angle of gypsum board, effectively solving the problems of existing technologies where the vertical edge measurement method using laser sensors is singular, laser sensor malfunctions leading to the discarding of qualified boards with acceptable vertical edge parameters, and subsequent formed boards having substandard vertical edges, resulting in batches of unqualified boards.

Detailed Implementation

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] like Figure 1 and Figure 2 As shown, the present invention provides a self-braking gypsum board vertical edge angle dual detection system, which includes a detection sensor 1, a follow-up detection component 2, and a braking structure 3.

[0057] The detection sensor 1 is set on the side of the conveyor roller. The detection sensor 1 emits a laser line towards the vertical edge of the gypsum board 4. After reflection, the laser line returns and the angle of the vertical edge of the gypsum board 4 is calculated.

[0058] The follow-up detection component 2 is set on both sides of the vertical edge of the gypsum board 4. The follow-up detection components 2 on both sides are set at different positions along the length of the gypsum board 4. The follow-up detection component 2 is provided with a follow-up plate 21. The inner side of the follow-up plate 21 is attached to the vertical edge of the gypsum board 4 and moves according to the tilt angle of the vertical edge of the gypsum board 4.

[0059] Braking structure 3 is located on the side of follower detection component 2. When follower plate 21 rotates to angle a, braking structure 3 is triggered to prevent follower plate 21 from continuing to rotate, thereby limiting the forward movement of plasterboard 4.

[0060] A limiting side plate 5 is provided at the same horizontal position as the follow-up detection component 2 and on the other side of the gypsum board 4. The limiting side plate 5 is in a vertical state and at least partially abuts against the side of the gypsum board 4.

[0061] In this invention, a follower plate 21 is provided inside the follower detection component 2. The inner side of the follower plate 21 is in contact with the vertical edge of the gypsum board 4 and moves according to the tilt angle of the vertical edge of the gypsum board 4. When the follower plate 21 rotates to angle a, the braking structure 3 is triggered to prevent the follower plate 21 from continuing to rotate, thereby limiting the forward movement of the gypsum board 4. On the one hand, the vertical edge of the gypsum board 4 is monitored in real time by the detection sensor 1. On the other hand, if the vertical edge of the gypsum board 4 does not meet the standard, the gypsum board 4 is braked to move forward. The dual detection method detects the gypsum board 4 with unqualified vertical edge, so that the unqualified gypsum board 4 is stopped from transportation. When both dual detections detect unqualified data, the unqualified gypsum board 4 is then subjected to a waste release procedure and the parameters of the molding process are adjusted to avoid the situation where the batch of boards is unqualified due to detection errors.

[0062] In this invention, the inner side of the follower plate 21 is attached to the vertical edge of the plasterboard 4 and moves according to the tilt angle of the vertical edge of the plasterboard 4. When the follower plate 21 rotates to angle a, the braking structure 3 is triggered to prevent the follower plate 21 from continuing to rotate, thereby limiting the forward movement of the plasterboard 4. The present invention provides two embodiments for both the follower detection component 2 and the braking structure 3, wherein the first embodiment is as follows:

[0063] like Figure 3 , Figure 4 and Figure 5 As shown, a movable column 22 is provided on the side of the follower plate 21. The movable column 22 is arranged along the width direction of the gypsum board 4. A mounting slot 23 is provided on the side of the movable column 22. The movable column 22 is movably arranged in the mounting slot 23. A first rotating seat 24 is provided at the end of the movable column 22. A second rotating seat 25 is provided on the follower plate 21. The first rotating seat 24 and the second rotating seat 25 are rotatably connected.

[0064] In the above embodiment, the first rotating seat 24 and the second rotating seat 25 are rotatably connected. The inner side of the follower plate 21 is attached to the side of the gypsum board 4 and can rotate. Since the position of the vertical edge of the gypsum board is not fixed, in order to fully fit with the gypsum board 4, the movable column 22 can move along the width direction of the gypsum board 4, so that the follower plate 21 can be slightly adjusted and translated along the width direction of the gypsum board 4 so that the follower plate 21 can be fully fitted.

[0065] Among them, a reset spring 218 is provided in the movable column 22 and the mounting slot 23, which enables the follower plate 21 to always be attached to the side of the gypsum board 4 under the action of the spring.

[0066] Correspondingly, the braking structure 3 adopts the following preferred embodiments, such as... Figure 4 and Figure 5As shown, the braking structure 3 includes a first connecting groove 31, a second connecting groove 32 and a third connecting groove 33 disposed in the movable column 22, and a first push rod 34 disposed in the first connecting groove 31. The first connecting groove 31, the second connecting groove 32 and the third connecting groove 33 are interconnected. The end of the second connecting groove 32 faces the inner wall of the mounting base 23, and the first push rod 34 abuts against the side of the follower plate 21.

[0067] A trapezoidal block 35 is provided in the second connecting groove 32, and a second push rod 36 is provided in the third connecting groove 33. The first push rod 34 and the second push rod 36 are parallel. The ends of the first push rod 34 and the second push rod 36 are provided with inclined surfaces 37, which respectively fit with the two sides of the trapezoidal block 35.

[0068] The rotation of the follower plate 21 drives the first push rod 34 to move into the first connecting groove 31. The first push rod 34 drives the trapezoidal block 35 to move upward in the second connecting groove 32, thereby driving the second push rod 36 to move outward in the third connecting groove 33. When the follower plate 21 rotates by an angle a, the second push rod 36 just moves to the point where its end abuts against the back of the follower plate 21. At this time, the follower plate 21 is blocked by the abutment of the second push rod 36 and can no longer rotate. Therefore, if the vertical edge angle of the gypsum board 4 is greater than a°, the follower plate 21 can block the movement of the gypsum board 4.

[0069] To prevent the gypsum board 4 from moving forward and causing the movable column 22 to move outward when the vertical edge angle of the gypsum board 4 is greater than a°, thus ensuring unimpeded transportation of the gypsum board 4, the present invention also incorporates the following design: Figure 6 As shown, a lifting block 38 is connected to the trapezoidal block 35. The lifting block 38 is connected to the second connecting groove 32 through a connecting spring 319. Several locking balls 39 are provided on the upper end of the lifting block 38. The inner wall of the mounting slot 23 is provided with locking grooves 310 at equal intervals. The locking balls 39 correspond to the locking grooves 310.

[0070] During the upward movement of the trapezoidal block 35, the lifting block 38 is driven to move upward. When the follower plate 21 rotates to a°, the locking ball 39 is just locked in the slot 310. At this time, the movable column 22 cannot move in the mounting slot 23 due to the locking action of the locking ball 39. Therefore, the angle of the follower plate 21 is limited and it cannot rotate or move outward. At this time, the side of the gypsum board 4 with an angle greater than a° cannot be transported forward by the follower plate 21 with an angle of a. The follower plate 21 blocks the forward transport of the gypsum board 4.

[0071] The function of the connecting spring 319 is to enable the first push rod 34 and the lifting block 38 to reset when the first push rod 34 is not pressed by the follower plate 21. In order to enable the second push rod 36 to reset at the same time, a spring can also be installed in the third connecting groove 33 so that the second push rod 36 can reset when the lifting block 38 does not apply force.

[0072] The second embodiment of the follow-up detection component 2 and the braking structure 3 is as follows:

[0073] like Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown, a positioning shaft post 26 is provided on the side of the follower plate 21, and a rotating cylinder 27 is rotatably mounted on the positioning shaft post 26. A slot 28 is opened on the side of the rotating cylinder 27 near the gypsum board 4. The follower plate 21 is installed at the opening of the slot 28. A connecting post 29 is provided on the side of the positioning shaft post 26. The positioning shaft post 26 and the connecting post 29 are perpendicular to each other. The connecting post 29 is arranged along the width direction of the gypsum board 4. A mounting slot 23 is provided on the side of the connecting post 29. The connecting post 29 is movably mounted in the mounting slot 23.

[0074] In the above embodiment, the follower plate 21 can rotate with the side of the plasterboard 4, and the rotating cylinder 27 rotates on the positioning shaft column 26. Since the position of the vertical side of the plasterboard 4 is not fixed, a connecting column 29 is also provided in this embodiment. The connecting column 29 moves in the mounting slot 23 and can be connected to the mounting slot 23 by the return spring 218. Correspondingly, the follower plate 21 can move along the width direction of the plasterboard 4. Under the spring force of the return spring 218, the follower plate 21 can fit against the side of the plasterboard 4.

[0075] In addition, in order to achieve braking of the follower plate 21, the present invention makes the following design, such as Figure 13 As shown, a snap-fit ​​seat 210 is provided on the side of the rotating cylinder 27, and a snap-fit ​​block 211 is provided on the side of the snap-fit ​​seat 210. The snap-fit ​​block 211 fits into the slot 28. The angle between the side of the snap-fit ​​block 211 and the side of the slot 28 is a°. The outer diameter of the snap-fit ​​seat 210 and the outer diameter of the positioning shaft 26 are the same as the inner diameter of the rotating cylinder 27.

[0076] like Figure 7 As shown, a fixed seat 213 is installed at one end of the positioning column 26, and a fixed column 214 is provided on the fixed seat 213. The end of the fixed column 214 is located inside the snap-fit ​​seat 210, and a push spring 215 is provided outside the fixed column 214. The fixed seat 213 and the snap-fit ​​seat 210 are connected by the push spring 215.

[0077] In the above embodiment, the angle of the snap-fit ​​seat 210 is fixed, but it can be translated. When the follower plate 21 rotates a° with the side of the plasterboard 4, the snap-fit ​​block 211 corresponds to the slot 28. At this time, under the action of the push spring 215, the snap-fit ​​seat 210 is pushed into the rotating cylinder 27, and the snap-fit ​​block 211 just enters the slot 28.

[0078] To ensure that the follower plate 21 can no longer rotate at this time, the inner groove of the locking seat 210 can be set as a non-circular groove that mates with the fixed shaft 214, such as a square groove. That is, the fixed shaft 214 itself is a cuboid structure, and the groove inside the locking seat 210 is also a square groove. In this case, the locking seat 210 can only translate and cannot rotate. Therefore, after the locking seat 210 enters the rotating cylinder 27, the locking block 211 and the slot 28 fit perfectly, and the locking seat 210 cannot rotate, which causes the follower plate 21 to also be unable to rotate at this time.

[0079] To reduce the resistance encountered by the follower plate 21 during its initial rotation, the present invention also incorporates the following design features: Figure 7 As shown, the snap-fit ​​block 211 is provided with a ball groove 216 on the side near the rotating cylinder 27, and a steel ball 217 is rotatably disposed in the ball groove 216, with at least a portion of the steel ball 217 abutting against the side of the rotating cylinder 27.

[0080] As the follower plate 21 rotates along the side of the plasterboard 4, the steel ball 217 rolls, and there is rolling friction between the rotating cylinder 27 and the locking block 211. The rolling friction itself is small, so it will not stop the rotation process of the follower plate 21.

[0081] To prevent the plasterboard 4 from moving forward and causing the connecting column 29 to move outward when the vertical edge angle of the plasterboard 4 is greater than a°, thus preventing the plasterboard 4 from being obstructed during transportation, the present invention also makes the following design: the snap-fit ​​seat 210 is fixedly provided with an abutment bolt 311 on the side near the rotating cylinder 27; the positioning shaft column 26 is provided with a first mounting groove 312; the connecting column 29 is provided with a second mounting groove 313 and a third mounting groove 314; the first mounting groove 312 is provided with a first top post 315; the end of the first top post 315 corresponds to the abutment bolt 311.

[0082] like Figure 7 and Figure 9 As shown, a movable rod 316 is provided in the second mounting groove 313, and a lifting bolt 317 is provided in the third mounting groove 314. A protrusion 320 is provided on the side of the lifting bolt 317. The protrusion 320 is connected to the third mounting groove 314 through a mounting spring 318. Inclined surfaces 37 are provided on both sides of the movable rod 316. Inclined surfaces 37 are provided at the ends of the lifting bolt 317 and the movable rod 316, and the ends of the lifting bolt 317 and the movable rod 316 are fitted with the movable rod 316. Several retaining balls 39 are provided on the lifting bolt 317. Retaining grooves 310 are provided at equal intervals on the inner wall of the mounting groove seat 23. The retaining balls 39 correspond to the retaining grooves 310.

[0083] When the follower plate 21 rotates by an angle greater than a°, and the follower plate 21 rotates exactly to a°, as follows: Figure 8 and Figure 11As shown, the locking seat 210 enters the rotating cylinder 27, driving the abutment bolt 311 into the first mounting groove 312. The first top post 315 moves towards the inside of the first mounting groove 312 under the pushing action of the abutment bolt 311. The movable rod 316 moves towards the inside of the second mounting groove 313 under the pushing action of the first top post 315. The lifting bolt 317 moves towards the opening of the third mounting groove 314 under the pushing action of the movable rod 316, so that the locking ball 39 moves to engage with the locking groove 310. At this time, the connecting post 29 cannot move in the mounting groove seat 23. That is to say, at this time, the follower plate 21 cannot rotate or move further. The side of the gypsum board 4 with an angle greater than a° cannot be transported forward by the follower plate 21 with an angle of a. The follower plate 21 blocks the forward transport of the gypsum board 4.

[0084] The purpose of installing spring 318 is to drive the lifting bolt 317, movable rod 316 and first top column 315 to reset, so as to facilitate subsequent detection and braking work. After the current gypsum board 4 braking work is completed, the locking seat 210 is reset to the initial position. There is no pressure force from the locking bolt 311. Under the action of spring 318, the lifting bolt 317, movable rod 316 and first top column 315 are all reset to the initial position.

[0085] This invention also provides a detection method for a self-braking gypsum board vertical edge angle dual detection system, comprising the following steps:

[0086] Step 100: Sensor 1 monitors the vertical edges of plasterboard 4 in real time;

[0087] Step 200: The gypsum board 4 is conveyed forward along the vertical edge of the gypsum board 4, and the gypsum board 21 rotates according to the tilt angle of the vertical edge of the gypsum board 4.

[0088] Step 300: When the follower plate 21 rotates to angle a, the braking structure 3 is triggered to prevent the follower plate 21 from continuing to rotate, so as to limit the forward transport action of the plasterboard 4.

[0089] Step 400: Adjust the parameters of the molding process based on the sensor detection results and the braking action of the gypsum board 4;

[0090] Step 500: If there is a discrepancy between the sensor detection results and the braking procedure of plasterboard 4, an alarm signal is sent.

[0091] The specific implementation process of steps 400 and 500 is as follows:

[0092] When the sensor detection result shows that it is not less than a° and the braking structure 3 is triggered, the gypsum board 4 is blocked and cannot be transported forward. At this time, it is necessary to adjust the parameters of the molding process. In actual application, the main steps are: adjusting the angle of the molding side plate (the molding side plate is used as a mold for molding the side of the gypsum board in the molding process), and after adjusting the parameters, adjusting the braking structure 3 of the follow-up detection component 2 away from the side of the gypsum board 4 so that the gypsum board 4 can continue to be transported and enter the waste disposal process.

[0093] Among them, the braking process of gypsum board 4 is also the braking process of the entire conveyor roller. In other words, the conveyor roller stops transporting based on the braking action of gypsum board 4, and adjusts the forming process parameters. This can minimize the output of boards with substandard vertical edges and facilitate repeated inspection of the vertical edges of the current gypsum board 4 to ensure that there are no detection errors in the inspection process.

[0094] When the sensor detection result shows that it is not less than a° and the braking structure 3 is not triggered, an alarm signal is issued and the detection sensor 1, the follow-up detection component 2, and the braking structure 3 are inspected and repaired.

[0095] When the sensor detection result shows less than a°, but the braking structure 3 has been triggered and the gypsum board 4 is prevented from being transported, an alarm signal should also be issued to inspect and repair the detection sensor 1, the follow-up detection component 2, and the braking structure 3.

[0096] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
