Description

Technical Field

[0001] The invention belongs to the technical field of sandwich panels and relates to a paving system for small-diameter bamboo core composite artificial panels and a working method thereof. Background Art

[0002] Sandwich panels, also known as core panels, consist of two layers of formed metal or other material panels with a core between them. The panels (i.e., the surface material) are typically stronger, while the core material is lighter in bulk density and weaker in strength. The panels are formed by gluing the surface material and core material together. Common surface materials include plywood, fiberboard, plastic, and sheet metal. The core material is typically balsa wood, rubber, cellulose acetate, plastic, resin-impregnated (or unimpregnated) paper or cloth, or a metal honeycomb structure.

[0003] Sandwich panels have attracted widespread attention due to their high specific strength, large and cheap core material, relatively high price but small amount of surface material, and low production cost.

[0004] Composite panels using bamboo as a core material are increasingly being used. However, the manufacturing process for bamboo-core composite panels requires cutting the bamboo, selecting bamboo of consistent axial length as the core material, and gluing the panels to the bamboo at each end. In the production of bamboo-core composite panels, small-diameter bamboo cores are typically used, and the axial length of the core is significantly greater than its diameter. The core of a bamboo-core composite panel is composed of multiple bamboo cores. These cores are manually placed on the glue-coated panels, requiring significant labor and resulting in low production efficiency.

[0005] Therefore, it is necessary to provide a paving system and a working method for small-diameter bamboo core composite wood-based panels to achieve automated paving of small-diameter bamboo core composite wood-based panels, reduce manpower consumption, and improve production efficiency. Summary of the Invention

During the production process, the upright bamboo cores are screened out by the posture adjustment device, and the bamboo cores are arranged regularly by the bamboo core pushing mechanism, and there is no need to manually place the bamboo core on the panel for gluing, which effectively reduces manpower consumption, improves production efficiency, and improves product production quality.

[0020] (1) Start the posture adjustment device 1, the posture adjustment device 1 screens out the upright bamboo cores, and the bamboo cores fall onto the perforated conveyor belt 2 in an upright state;

[0021] (2) The perforated conveyor belt 2 conveys the bamboo core in an upright state to the tempered glass smoothing platform 301 of the bamboo core pushing mechanism 3;

[0022] (3) Start the electric push rod 303, which shortens and drives the push plate 306 to descend. When the push plate 306 descends until its bottom surface contacts the surface of the tempered glass smooth table 301, stop the electric push rod 303;

[0023] (4) Start the first electric guide rail 302, which drives the push plate 306 to push the upright bamboo core from one end of the U-shaped enclosure 305 to the other end, until the push plate 306 pushes the upright bamboo core to the other end of the U-shaped enclosure 305 and the bamboo cores are in close contact with each other, completing one push, and then start the electric push rod 303, which extends and drives the push plate 306 to rise.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to specific embodiments.

[0037] like Figure 1-6As shown, the paving system includes a posture adjustment device 1, a punching conveyor belt 2, a bamboo core pushing mechanism 3, a robotic arm 4, and a master control system. The posture adjustment device 1 includes a box 101, a base 102, a spring 103, a mounting block 104, and a vibration motor 105. The mounting block 104 is provided on the outer wall of the box 101. The base 102 is connected to the mounting block 104 through a spring 103. The vibration motor 105 is fixedly mounted on the outer wall of the box 101. The bottom surface of the box 101 is The screen, the box 101 is located directly above the perforated conveyor belt 2, the mesh of the screen on the bottom surface of the posture adjustment device 1 is square, and the mesh size is the same as the size of the circumscribed square of the circular cross-section of the bamboo core with the largest diameter, the distance s=h+10mm between the conveying surface of the perforated conveyor belt 2 and the screen of the posture adjustment device 1, where h is the axial length of the bamboo core, the bamboo core pushing mechanism 3 is arranged at the material output end of the perforated conveyor belt 2 and docked with the perforated conveyor belt 2, and the robotic arm 4 is arranged on one side of the bamboo core pushing mechanism 3;

[0038] The vibration motor 105 , the punching conveyor belt 2 , and the robotic arm 4 are electrically connected to the master control system respectively.

[0039] When laying bamboo core composite artificial board, first add bamboo cores with the same axial length into the box 101, turn on the vibration motor 105, and the vibration motor 105 drives the box 101 to vibrate. The vibration effect can change the posture of the bamboo core in the box 101. For example, the bamboo core with an oblique or horizontal axial direction will become vertical under the action of vibration. The bottom surface of the posture adjustment device 1 is a screen. The square structure size of the screen hole is the same as the circumscribed square size of the circular cross-section of the bamboo core. In the manufacturing process of the bamboo core artificial composite board, the bamboo core used has the characteristic that the axial length is greater than its diameter. Therefore, when the bamboo core is in a non-upright state, it cannot pass through the screen hole and remains in the posture adjustment device 1. Only the bamboo core in the upright state can pass through the screen hole, and in the process of falling from the screen hole, the screen hole has a limiting effect on the bamboo core. The bamboo core can be kept in an upright state when it falls. When the bamboo core at the lowest part of the box body 1 is in an upright state, it will fall from the sieve hole. Since the distance between the conveying surface of the perforated conveyor belt 2 and the screen of the posture adjustment device 1 is controlled, the falling time of the bamboo core in the air can be reduced, so that the bamboo core can quickly reach the perforated conveyor belt 2 after falling from the sieve hole. When the transportation speed of the perforated conveyor belt 2 is slow, the bamboo core will not fall after reaching the perforated conveyor belt 2. Therefore, after the bamboo core reaches the perforated conveyor belt 2, it can maintain an upright state and be transported to the bamboo core pushing mechanism 3 by the perforated conveyor belt 2. After the bamboo core pushing mechanism 3 arranges the bamboo core in a regular pattern, the panel 6 is placed on the bamboo core through the robotic arm 4, so that the bamboo core and the panel 6 are bonded. It is only necessary to set the preset program of the robotic arm 4, and the robotic arm 4 can work according to the preset program. Although the diameters of the bamboo cores in the box 101 are different, the axial length of the small-diameter bamboo cores used to make the bamboo core artificial composite board is much larger than its diameter. Therefore, the sieve hole size is small, and even the bamboo cores with smaller diameters cannot pass through the sieve hole when they are not upright.

[0040] The staff can control the posture adjustment device 1, the punched conveyor belt 2, and the start and stop of the robot arm 4 through the master control system, and the transport speed of the punched conveyor belt 2 can be preset to keep its transport speed at a relatively slow state.

[0041] Baffles can be installed on both sides of the perforated conveyor belt 2 to prevent the bamboo core from falling out of the perforated conveyor belt 2 during transportation.

[0042] The paving system further includes a multi-suction vacuum cleaner 5, the suction ports of which are densely laid below the upper belt of the perforated conveyor belt 2 and facing the upper belt of the perforated conveyor belt 2;

[0043] The multi-suction-port vacuum cleaner 5 is electrically connected to the master control system.

[0044] When the perforated conveyor belt 2 is transporting the bamboo core, the multi-suction port vacuum cleaner 5 can absorb the dust and the like in the environment. At the same time, when the multi-suction port vacuum cleaner 5 is working, it may produce a certain suction effect on the bamboo core being transported. It is located below the bamboo core, which can make the suction force on the bamboo core directed downward, minimizing the radial force on the bamboo core and increasing the possibility of its tipping over. During use, it should be noted that the suction force of the multi-suction port vacuum cleaner 5 is controlled within a smaller range to avoid the bamboo core being adsorbed on the perforated conveyor belt 2, which affects the conveying process of the bamboo core by the perforated conveyor belt 2.

[0045] The staff can control the start and stop of the multi-suction vacuum cleaner 5 through the master control system.

[0046] The bamboo core pushing mechanism 3 includes a tempered glass smoothing platform 301, a first electric guide rail 302, an electric push rod 303, a first inverted U-shaped frame 304, a U-shaped enclosure 305, and a push plate 306. The surface of the tempered glass smoothing platform 301 is at the same height as the conveying surface of the punching conveyor belt 2. The tempered glass smoothing platform 301 extends to dock with the punching conveyor belt 2. The first electric guide rail 302 is fixedly installed on both sides of the tempered glass smoothing platform 301. The electric push rod 303 is fixedly installed on the slider of the first electric guide rail 302. , the end of the first inverted U-shaped frame 304 is fixedly connected to the end of the telescopic section of the electric push rod 303, and the electric push rod 303 drives the first inverted U-shaped frame 304 to move up and down, and the U-shaped enclosure 305 is fixedly mounted on the table surface of the tempered glass smoothing table 301, and the opening direction of the U-shaped enclosure 305 faces the punching conveyor belt 2, and the push plate 306 is movably arranged in the U-shaped enclosure 305, and the push plate 306 is fixedly connected to the first inverted U-shaped frame 304, and one end of the first electric guide rail 302 extends to the side of the punching conveyor belt 2;

[0047] The first electric guide rail 302 and the electric push rod 303 are electrically connected to the master control system.

[0048] After the punching conveyor belt 2 transports the upright bamboo core to the tempered glass smooth platform 301, the upright bamboo core enters the U-shaped enclosure 305. At this time, the electric push rod 303 is in an extended state, the first inverted U-shaped frame 304 is in an elevated state, and the push plate 306 is also in a higher position, which does not hinder the bamboo core from entering the U-shaped enclosure 305. When a certain amount of upright bamboo core is transported to the tempered glass smooth platform 301 by the punching conveyor belt 2 and enters the U-shaped enclosure 305, the electric push rod 303 is started, the electric push rod 303 is shortened, and the first inverted U-shaped frame is driven 304 descends, thereby driving the push plate 306 to descend. When the push plate 306 descends and its bottom surface contacts the surface of the tempered glass smooth table 301, the electric push rod 303 can be stopped, so that the push plate 306 stops descending and remains in the current position. Then the first electric guide rail 302 is started, and the slider of the first electric guide rail 302 slides along the track, driving the first inverted U-shaped frame 304 to move, thereby driving the push plate 306 to move. At this time, the push plate 306 moves inside the U-shaped enclosure 305 and pushes the bamboo core from one end of the U-shaped enclosure 305 to the other end. The push plate 306 pushes the bamboo core. After the bamboo core moves, it will be blocked by the other end of the U-shaped fence 305. The bamboo core between the push plate 306 and the U-shaped fence 305 is in close contact with the force. After the push plate 306 pushes part of the bamboo core to close contact, the first electric guide rail 302 is stopped, and the electric push rod 303 is turned on again. The electric push rod 303 extends, driving the push plate 306 to rise until the push plate 306 is above the bamboo core, and then the first electric guide rail 302 is started to drive the push plate 306 back to the starting point of the push, and then the aforementioned process is repeated to push the subsequent bamboo cores. Push it into close contact until the total area of ​​the tightly contacted bamboo core in the U-shaped enclosure 305 (due to the different diameters of the bamboo cores, there may be gaps after all the bamboo cores are in close contact, and the total area also includes the gap area) meets the requirements for making bamboo core composite artificial panels, then control the electric push rod 303 to extend, the U-shaped enclosure 305 to rise, and then control the slider of the first electric guide rail 302 to slide to the pushing starting point position, so that the first inverted U-shaped frame 304 leaves the area above the U-shaped enclosure 305, so as not to block the placement of the panel 6 by the robot arm 4. The electric end of the first guide rail extends to the side of the punching conveyor belt 2, and the extension length of the first electric guide rail to the side of the punching conveyor belt 2 is greater than the extension length of the tempered glass smoothing table 301 to the punching conveyor belt 2, so as to prevent the robot arm 4 from blocking the placement of the panel 6. Figure 1For example, one end of the first electric guide rail extending to the side of the punching conveyor belt 2 is located on the left side of the end where the tempered glass smooth platform 301 and the punching conveyor belt 2 are connected, so that the slider of the first electric guide rail 302 can slide to the side position of the punching conveyor belt 2, so that when the first electric guide rail 302 drives the push plate 306 back to the pushing starting point, the position of the pushing starting point of the push plate 306 is on the punching conveyor belt 2. Since the conveying speed of the punching conveyor belt 2 is slow, the bamboo core may be conveyed to the tempered glass smooth platform 301 and then stop at the entrance of the U-shaped enclosure 305. At this time, the bamboo core may block the descending path of the push plate 306. If the pushing starting point is located above the conveying surface of the punching conveyor belt 2, even if there is a bamboo core under the push plate 306 at a certain moment, the bamboo core can be conveyed forward by the punching conveyor belt 2, so that the bamboo core avoids the descending path of the push plate 306.

[0049] The height of the push plate 306 is equal to the axial length of the bamboo core, thereby reducing the probability of the bamboo core being pushed down by the push plate 306.

[0050] A flexible pressure sensor 307 is fixedly provided on the contact surface of the push plate 306 with the bamboo core, and the flexible pressure sensor 307 is connected to the master control system for communication. A photoelectric sensor 311 is installed on the top of the first inverted U-shaped frame 304, and the photoelectric sensor 311 is connected to the master control system for communication.

[0051] When the bamboo core is in close contact with the push plate 306 in the space enclosed by the U-shaped enclosure 305, the bamboo core cannot move. When the push plate 306 pushes the bamboo core again, the pushing surface of the push plate 306 will be subjected to the reaction force of the bamboo core. Then, after the flexible pressure sensor 307 senses the pressure, it transmits a signal to the master control system. After receiving the signal, the master control system determines that the push plate 306 needs to push again, and controls the first electric guide rail 302 to stop, and at the same time controls the electric push rod 303 to extend, and then controls the slider of the first electric guide rail 302 to slide back to the pushing starting point position, and continues to push the subsequent bamboo core. The electric push rod 303 extends, the first electric guide rail 302 slides to the starting point, the electric push rod 303 shortens, and the slider of the first electric guide rail 302 slides in the pushing direction of the bamboo core. All of this can be achieved through a program preset in the master control system. When the master control system needs to control the electric push rod 303 to shorten according to the preset program, the photoelectric sensor 311 can sense whether there is a bamboo core underneath it. If the photoelectric sensor 311 senses the presence of a bamboo core, it transmits a signal to the master control system. After receiving the signal, the master control system controls the electric push rod 303 to temporarily stop shortening, and the push plate 306 will not descend. When the photoelectric sensor 311 senses the absence of a bamboo core, it sends a signal to the master control system. The master control system then controls the electric push rod 303 to shorten, driving the push plate 306 to descend. When the preset time point for the push plate 306 to push the bamboo core is reached, the master control system simultaneously controls the posture adjustment device 1 and the punching conveyor belt 2 to suspend operation. After the master control system receives the signal transmitted by the flexible pressure sensor 307, it controls the electric push rod 303 to extend and controls the posture adjustment device 1 and the punching conveyor belt 2 to resume operation. After receiving the signal from the flexible pressure sensor 307, the master control system controls the corresponding components according to the preset program, so that the push plate 306 can automatically push the bamboo core in a cycle.

[0052] The bamboo core pushing mechanism 3 also includes an industrial camera 308, a second inverted U-shaped frame 309, and a second electric guide rail 310. The second electric guide rail 310 is fixedly installed on both sides of the tempered glass smoothing platform 301. The second electric guide rail 310 is located below the first electric guide rail 302. The end of the second inverted U-shaped frame 309 is fixedly connected to the slider of the second electric guide rail 301. The first inverted U-shaped frame 304 is inside the second inverted U-shaped frame 309. The industrial camera 308 is fixedly installed on the second inverted U-shaped frame 309, and the industrial camera 308 takes an image of the surface of the tempered glass smoothing platform 301;

[0053] The second electric guide rail 310 and the industrial camera 308 are electrically connected to the master control system.

[0054] When the push plate 306 pushes all the bamboo cores needed to produce a bamboo core composite artificial board into the U-shaped enclosure 305 and the bamboo cores are in close contact, the industrial camera 308 can capture the total area of ​​bamboo cores on the tempered glass smoothing table 301 and transmit the signal to the master control system. The master control system determines whether the panel 6 gluing operation can be performed based on the image captured by the industrial camera 308. If it can, the master control system controls the sliders of the first electric guide rail 302 and the second electric guide rail 310 to slide to the end of the track where the perforated conveyor belt 2 is located and stops. It then controls the robot arm 4 to operate and place the pre-coated panel 6 on the bamboo core. Through the signal transmitted by the industrial camera 308, the master control system can automatically determine whether the push plate 306 has completed its work, thereby further improving the system's automation level and reducing the workload of manual participation. Manual personnel can simply observe and deal with individual abnormal situations. During normal operation, no manual intervention is required.

[0055] The master control system is a PLC or DCS system.

[0056] The above paving system works according to the following steps:

[0057] (1) Start the posture adjustment device 1, the posture adjustment device 1 screens out the upright bamboo cores, and the bamboo cores fall onto the perforated conveyor belt 2 in an upright state;

[0058] (2) The perforated conveyor belt 2 conveys the bamboo core in an upright state to the tempered glass smoothing platform 301 of the bamboo core pushing mechanism 3;

[0059] (3) Start the electric push rod 303, which shortens and drives the push plate 306 to descend. When the push plate 306 descends until its bottom surface contacts the surface of the tempered glass smooth table 301, stop the electric push rod 303;

[0060] (4) Start the first electric guide rail 302, which drives the push plate 306 to push the upright bamboo core from one end of the U-shaped enclosure 305 to the other end, until the push plate 306 pushes the upright bamboo core to the other end of the U-shaped enclosure 305 and the bamboo cores are in close contact with each other, completing one push, and then start the electric push rod 303, which extends and drives the push plate 306 to rise. After the push plate 306 rises above the upright bamboo core, start the first electric guide rail 302, which drives the push plate 306 to return to the starting position and continue to push the upright bamboo core.
