Description

Technical Field

[0001] The present application relates to the technical field of building material processing equipment, and in particular to a device for automatically identifying and conveying defective gypsum boards. Background Art

[0002] Gypsum board is made from natural gypsum. Raw gypsum is calcined to remove moisture, resulting in gypsum plaster. The gypsum plaster is then mixed with water to create gypsum slurry. The gypsum slurry is transported on a conveyor belt and goes through processes such as de-bubbling, leveling, and extrusion to form the slurry. It is then attached to paper and dried to form the finished gypsum board. The finished gypsum boards are then stacked and packaged. During stacking, the finished gypsum boards are inspected, with defective boards removed and placed in a stack. Acceptable boards are then packaged.

[0003] The existing method of removing bad boards is to first splash ink on the protective paper, and then use the color separation detection equipment to obtain the gypsum board with ink to control the rejection mechanism to push the bad board to the bad board pile. Among them, unqualified products include: cracks on the board surface, uneven thickness of the board surface, and debonding at the paper joints on the board. In the existing technology, it is necessary to stop the transmission of the gypsum board when kicking out the bad board, which affects the overall production efficiency of the equipment; in addition, only single-sided crack detection can be achieved, and the maneuverability and flexibility of the entire system are not high. Moreover, unqualified products need to rely on the early fixed-point ink splashing treatment, and the rejection mechanism determines whether they need to be rejected based on whether there is ink splashing. This ink splashing method not only affects the appearance but may also scratch the surface of the gypsum board during the ink splashing process. Utility Model Content

Furthermore, the phrases "in one embodiment" or "in an embodiment" appearing throughout this specification do not necessarily refer to the same embodiment.

[0029] Gypsum board is a common material in the construction industry. Made from natural gypsum, it undergoes multiple processes, including pulping and molding. During the production process, defective boards must be identified and removed from the production line for reprocessing or other repairs. The current method for removing defective boards involves first applying ink to the face paper. Once a color separation inspection device detects an inked gypsum board, a rejection mechanism pushes the defective board to a stack. Quality issues or defective products include cracks on the board surface, uneven thickness, and debonding at the paper joint. Removing defective boards requires stopping the gypsum board conveyor, impacting overall production efficiency. Furthermore, only crack detection on a single side is possible, limiting the system's maneuverability and flexibility. Furthermore, defective boards require a targeted ink-spraying treatment, with the rejection mechanism determining whether to remove them based on the presence of ink. This method not only affects the appearance but also risks scratching the gypsum board surface during the ink-spraying process. Based on this, the utility model provides an automatic identification and conveying device for defective gypsum boards, which is described in detail below.

[0030] See also Figures 1 to 4 As shown, the automatic identification and conveying device for defective gypsum boards provided by the present invention includes a conveying mechanism, a transfer manipulator 4, a detector, and a flipping assembly arranged on the upper and lower layers, wherein the detector includes a primary detector 5 and a secondary detector 6, the upper conveying mechanism 1 includes: a first detection position 11, a second detection position 12, a docking position 13, and a material removal position 14, and a material stack 3 is included between the upper conveying mechanism 1 and the lower conveying mechanism 2, wherein the material stack 3 is arranged directly below the material removal position 14 and is slidably connected to the lower conveying mechanism 2. The aforementioned lower conveying mechanism 2 is configured to transport the aforementioned material stack 3; the material stack 3 contains defective boards that have been detected and removed from the transmission mechanism, and after the stacking is completed, the lower conveying mechanism 2 pushes the entire stack out.

[0031] like Figure 1 and Figure 2 As shown, the aforementioned transfer robot 4 includes a first transfer arm 41, a second transfer arm 42 and a motor at right angles to each other. The first transfer arm 41 and the second transfer arm 42 are both provided with a limit clamp 3. The limit clamp 3 is set to fix the gypsum board to prevent the gypsum board from detaching from the transfer arm or shifting relative to the transfer arm when being transferred. In addition, the first transfer arm 41 corresponds to the docking position 13, and the second transfer arm 42 corresponds to the ejection position 14. One end of the first transfer arm 41 and the second transfer arm 42 intersect, and a motor is set at the intersection position, and the motor is used to control the two transfer arms to rotate and remove bad boards.

[0032] The detailed description is as follows: the first transfer arm 41 waits at the docking position 13. When the gypsum board is transported to the docking position 13 by the upper material transport mechanism 1, it indicates that the board is a bad board and needs to be removed. At this time, the first transfer arm 41 obtains the bad board and the motor controls it to rotate right. When it reaches the removal position 14, the bad board is stored in the unloading stack 3. At this time, the detection and removal of the bad board are completed. During this process, the normal gypsum board continues to be transported along the original transmission trajectory. That is, the utility model utilizes the transfer robot 4 and the material transport mechanism arranged in the upper and lower layers to carry out the gypsum board transmission and bad board removal in parallel, which does not affect the transmission speed of the gypsum board on the main line and improves the efficiency of the transmission system.

[0033] In addition, to detect the front and back sides of the gypsum board, a flip assembly is provided between the first detection position 11 and the second detection position 12. The flip assembly includes a first and second staggered prongs 71, 72, and a controller. When flipping is not required, the angle between the first and second prongs 71, 72 is 180° and is lower than the transmission surface of the gypsum board. When flipping is required, the first and second prongs 71 and 72 are controlled to flip upward 90°, and the second prongs 72 are controlled to flip upward 90° at the same time. During the flipping process, the gypsum board is kept between the first and second prongs 71, 72 to prevent the gypsum board from slipping or shifting during the flipping process. The control and drive of the first and second prongs 71, 72 are independent of each other, so that the direction of the first and second prongs 71, 72 can be independently controlled, which also facilitates maintenance.

[0034] In this embodiment, the aforementioned secondary detector 6 is signal-connected to the primary detector 5, and the detection logic of the primary detector 5 and the secondary detector 6 are independent of each other or arranged in parallel. This arrangement is intended to ensure that when the primary detector 5 detects that the gypsum board is defective, the secondary detector 6 will no longer detect it and will directly transfer the defective board to the docking position 13 for delivery by the transfer robot 4. In addition, when the primary detector 5 does not detect any quality problems, the board will be transferred to the secondary detector 6 for further inspection. If the secondary detector 6 detects any quality problems, the defective board will be rejected. That is, the detection logic of the two detectors does not include the determination that a board is defective only when a defective board is detected at the same time. The signal connection between the two detectors facilitates the sharing of detection parameters and communication of detection results to improve the quality of detection.

[0035] In addition, this embodiment includes a controller. Both the primary detector 5 and the secondary detector 6 are cameras, and the controller is signal-connected to the cameras. The controller captures images from the two detectors and determines the type of defective board based on pre-set judgment logic. Furthermore, a coding device can be installed at the detector location to display information such as the type of defective board detected and the number of corresponding problem points, making it easier for repair personnel to scan and obtain information, facilitating maintenance.

[0036] like Figure 4As shown, the bottom connection between the opposing surfaces of the first prongs 71 and the second prongs 72 includes a cushioning pad 700. When the gypsum board is flipped, the surface of the gypsum board needs to adhere to the surfaces of the first prongs 71 and the second prongs 72. In addition, the bottom side of the gypsum board will rub against the flipping mechanism 7. To protect the gypsum board, cushioning pads 700 are provided on the contact surface and in the gaps with the gypsum board to prevent wear and damage.

[0037] In addition, the aforementioned upper material transport mechanism 1 and lower material transport mechanism 2 both include: a bracket 100, a transmission belt 101 and a support roller 102, the two ends of the support roller 102 are socketed with the side walls of the bracket 100, and the transmission direction of the transmission belt is perpendicular to the axial direction of the support roller 102, wherein the surface of the support roller 102 is provided with a polishing layer to increase its smoothness and prevent scratches on the gypsum board.

[0038] like Figure 3 As shown in the figure, taking the upper material transport mechanism 1 as an example, the transmission belt 101 drags the gypsum board to move, and after the moving gypsum board contacts the support roller 102, the support roller 102 rotates to assist the transmission belt in driving the gypsum board to move; the dual dragging effect of the support roller 102 and the transmission belt 101 improves the transmission performance of the mechanism.

[0039] Finally, the utility model provides an automatic identification and conveying device for defective gypsum boards, including a material transport mechanism, a transfer manipulator 4, a detector and a flip assembly arranged on the upper and lower layers. The detector includes a first-level detector 5 and a second-level detector 6. The upper material transport mechanism 1 includes: a first detection position 11, a second detection position 12, a docking position 13, and a material removal position 14. A material unloading stack 3 is included between the upper material transport mechanism 1 and the lower material transport mechanism 2. The material unloading stack 3 is arranged just below the material removal position 14 and is slidably connected to the lower material transport mechanism 2; the transfer manipulator 4 includes The first and second transfer arms 41, 42, and motors are arranged at right angles to each other. A limit clamp 3 is provided on each of the first and second transfer arms 41, 42. The first transfer arm 41 corresponds to the docking position 13, and the second transfer arm 42 corresponds to the ejection position 14. One end of the first and second transfer arms 41, 42 intersect, and the motor is located at the intersection. The flip assembly is located between the first detection position 11 and the second detection position 12 and includes a first and second slotting teeth 71, 72 arranged in an offset manner. The control and drive of the first and second slotting teeth 71, 72 are independent of each other. This utility model not only improves the transmission efficiency and bad board rejection efficiency of the gypsum board transmission system, but also improves the detection quality of bad boards.
