Description

Technical Field

[0001] This invention relates to the field of asphalt shingle conveying technology, specifically to an automatic shingle stacking machine for conveying asphalt shingles. Background Technology

[0002] Asphalt shingles are a new type of high-tech waterproof building material and a novel roofing material used for waterproofing building roofs. They are made with fiberglass felt as the base, impregnated with high-quality petroleum asphalt, covered with colored mineral granules on one side, and coated with a separating material on the other. These tile-shaped waterproof roofing sheets offer excellent waterproofing and decorative properties, a rich variety of colors and styles, are lightweight and have a fine surface, and are easy to install.

[0003] In the production of asphalt shingles, whole asphalt shingles are first produced. Then, using a cutting mold, the asphalt shingles are cut into pre-designed shapes according to the actual needs. Because asphalt has a certain degree of adhesion and elasticity, and in order to improve the cutting efficiency of asphalt shingles, and because shape cutting is mostly done by pressure cutting, some asphalt shingles will be connected together after cutting. They need to be separated manually. At the same time, the separated asphalt shingles are stacked, packaged, and transported out of the factory. The manual method greatly reduces production efficiency. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automatic shingle stacking machine for conveying asphalt shingles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic shingle stacking machine for conveying asphalt shingles, comprising a frame, a conveyor line, a pulling mechanism, a stacking mechanism, and an output line. The conveyor line is mounted on the frame, and its input end matches the output end of the conveyor line used in the asphalt shingle cutting process. Four pulling mechanisms are provided, respectively located on the front and rear left and right sides of the conveyor line. A detection device is provided on the frame at the edge of the conveyor line for each pulling mechanism.

[0006] The pulling mechanism includes a slide rail, a cylinder, a mounting bracket, and a pneumatic claw. The slide rail is mounted on the frame above the conveyor line. The mounting bracket is slidably mounted on the slide rail. The cylinder is mounted on the frame, and the piston end of the cylinder is connected to the mounting bracket. A crossbar is provided below the mounting bracket, and the crossbar is flush with the conveyor line. The pneumatic claw is mounted on the crossbar, and the gripper of the pneumatic claw faces the conveyor line and is located at the edge of the conveyor line.

[0007] The stacking mechanism includes a second cylinder, a lifting frame, and a platform. The second cylinder is mounted on the frame, and the piston end of the second cylinder is set vertically downward. The lifting frame is mounted on the second cylinder and is located below the crossbar. Multiple platforms are provided, and the multiple platforms are arranged horizontally on the lifting frame. There is a gap between adjacent platforms. The bottom of the lifting frame is provided with a through groove corresponding to each gap. The width of the through groove is the same as the width of the corresponding gap.

[0008] There are four stacking mechanisms, each corresponding to one of the pulling mechanisms.

[0009] There are two output lines, each corresponding to one of the two stacking mechanisms that are symmetrically arranged to the left and right, and the conveyor belt of the output line is located at the through groove.

[0010] Preferably, the detection device is an infrared photocell sensor, which detects whether there are asphalt shingles to be stacked on the conveyor line.

[0011] Preferably, a full material detection device is provided on the frame corresponding to the output line.

[0012] Preferably, the full material detection device is an infrared photocell sensor installed on the left and right sides of the stacking mechanism, and one full material detection device is installed at each stacking mechanism.

[0013] Preferably, a laser distance sensor is installed on the frame directly above the platform.

[0014] Preferably, the crossbar is provided with multiple pneumatic claws.

[0015] To achieve the above objectives, the present invention also provides the following technical solution: a method for using an automatic asphalt shingle stacking machine, comprising the following steps:

[0016] (1) Transfer the asphalt shingles to be stacked from the upper conveyor line to the conveyor line of this technology;

[0017] (2) The platform moves upward by the action of cylinder two, and the distance of the platform rise is detected by the laser distance sensor. When the platform rises to the preset position, cylinder two stops running.

[0018] (3) When the asphalt shingle moves to the detection device, the detection signal is triggered, the pneumatic claw clamps the asphalt shingle, and then the cylinder pushes the pneumatic claw away from the conveyor line.

[0019] (4) When the cylinder extends to the preset distance, the pneumatic claw releases the gripper, the asphalt shingle detaches from the pneumatic claw and falls onto the platform;

[0020] (5) The conveyor line runs without stopping. When the previous pneumatic claw returns to its original position, the asphalt shingles are conveyed to the next pneumatic claw for stacking.

[0021] (6) When the asphalt shingles are two adhered together, the two asphalt shingles are moved horizontally to the two pneumatic claws in the first position through the conveyor line. Then the two pneumatic claws clamp the left and right sides of the asphalt shingles at the same time. By pushing the cylinder, the pneumatic claws on both sides act in opposite directions to pull and separate the asphalt shingles and place them on the corresponding platform respectively.

[0022] (7) If the pneumatic claw in the first position is not in working state and has not returned to its original position, and the asphalt shingles are two stuck together, the two detection devices in the first position will detect the left and right sides of the asphalt shingles at the same time. At this time, the pneumatic claw in the first position will not run, and the conveyor line will transport the asphalt shingles to the two pneumatic claws in the second position for clamping and pulling. Through the pulling and coordinating of the two work positions, the conveyor line can be operated without stopping.

[0023] (8) When the asphalt shingles stacked on the platform reach a certain thickness, the laser distance sensor detects the current stacking thickness of the asphalt shingles on the platform. Then, the cylinder moves down, driving the platform to move down, and enabling more asphalt shingles to be stacked. When the platform moves down to the point where it is detected by the full material detection device, the asphalt shingles at the bottom of the platform contact the conveyor belt of the output line. At this time, the output line runs, removing the asphalt shingles from the platform. Then the platform returns to the high position to continue the next stacking of asphalt shingles.

[0024] (9) The asphalt shingles removed by the output line can be output by the next process conveyor line, or they can be manually removed from the output line for subsequent packaging.

[0025] Compared with the prior art, the beneficial effects of the present invention are: asphalt shingles can be automatically stacked, and when asphalt shingles stick together, they can be automatically separated, thereby improving the stacking efficiency of asphalt shingles, reducing manual operation processes, and further improving production efficiency.

[0034] 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.

[0035] Please see Figures 1 to 7 This invention provides a technical solution: an automatic shingle stacking machine for conveying asphalt shingles, comprising a frame, a conveyor line, a pulling mechanism, a stacking mechanism, and an output line. The conveyor line is mounted on the frame, and its input end matches the output end of the conveyor line used in the asphalt shingle cutting process. Four pulling mechanisms are provided, respectively located on the left and right sides of the front and rear ends of the conveyor line. A detection device is provided on the frame at the edge of the conveyor line for each pulling mechanism.

[0036] The pulling mechanism includes a slide rail, a cylinder, a mounting bracket, and a pneumatic claw. The slide rail is mounted on the frame above the conveyor line. The mounting bracket is slidably mounted on the slide rail. The cylinder is mounted on the frame, and the piston end of the cylinder is connected to the mounting bracket. A crossbar is provided below the mounting bracket, and the crossbar is flush with the conveyor line. The pneumatic claw is mounted on the crossbar, and the gripper of the pneumatic claw faces the conveyor line and is located at the edge of the conveyor line.

[0037] The stacking mechanism includes a second cylinder, a lifting frame, and a platform. The second cylinder is mounted on the frame, and the piston end of the second cylinder is set vertically downward. The lifting frame is mounted on the second cylinder and is located below the crossbar. Multiple platforms are provided, and the multiple platforms are arranged horizontally on the lifting frame. There is a gap between adjacent platforms. The bottom of the lifting frame is provided with a through groove corresponding to each gap. The width of the through groove is the same as the width of the corresponding gap.

[0038] There are four stacking mechanisms, each corresponding to one of the pulling mechanisms.

[0039] There are two output lines, each corresponding to one of the two stacking mechanisms that are symmetrically arranged to the left and right, and the conveyor belt of the output line is located at the through groove.

[0040] The output line can rotate in both directions. When the asphalt shingles on one side of the platform are full, the output line can rotate in that direction, causing the asphalt shingles to be detached from the platform and output. After output, the line stops running. When the asphalt shingles on the other side of the platform are full, the conveyor line rotates in the opposite direction, causing the asphalt shingles on the other side to be output.

[0041] The detection device is an infrared photocell sensor, which detects whether there are asphalt shingles to be stacked on the conveyor line.

[0042] By setting up a detection device, it is possible to detect whether the asphalt shingles have moved to the corresponding position, thus preventing the asphalt shingles from not being delivered to the correct position and the pneumatic claw from operating incorrectly, and ensuring the stable operation of the asphalt shingle conveyor line.

[0043] A full material detection device is installed on the frame corresponding to the output line. The full material detection device is an infrared photocell sensor installed on the left and right sides of the stacking mechanism. One full material detection device is installed at each stacking mechanism.

[0044] By setting up a full material detection device, the output line is triggered when the asphalt shingles stacked on the platform reach the full material state, and the stacked asphalt shingles are removed from the platform, ensuring that the platform can continue to be stacked for the next time. At the same time, the asphalt shingles stacked in the previous process can be packaged and put into storage.

[0045] A laser distance sensor is installed on the frame directly above the platform. The laser distance sensor detects the thickness of the asphalt shingles stacked on the platform to prevent over-stacking.

[0046] The crossbar is equipped with multiple pneumatic claws, which work together to achieve stable clamping of the asphalt shingles.

[0047] A method for using an automatic asphalt shingle stacking machine for conveying asphalt shingles, comprising the following steps:

[0048] (1) Transfer the asphalt shingles to be stacked from the upper conveyor line to the conveyor line of this technology;

[0049] (2) The platform moves upward by the action of cylinder two, and the distance of the platform rise is detected by the laser distance sensor. When the platform rises to the preset position, cylinder two stops running.

[0050] (3) When the asphalt shingle moves to the detection device, the detection signal is triggered, the pneumatic claw clamps the asphalt shingle, and then the cylinder pushes the pneumatic claw away from the conveyor line.

[0051] (4) When the cylinder extends to the preset distance, the pneumatic claw releases the gripper, the asphalt shingle detaches from the pneumatic claw and falls onto the platform;

[0052] (5) The conveyor line runs without stopping. When the previous pneumatic claw returns to its original position, the asphalt shingles are conveyed to the next pneumatic claw for stacking.

[0053] (6) When the asphalt shingles are two adhered together, the two asphalt shingles are moved horizontally to the two pneumatic claws in the first position through the conveyor line. Then the two pneumatic claws clamp the left and right sides of the asphalt shingles at the same time. By pushing the cylinder, the pneumatic claws on both sides act in opposite directions to pull and separate the asphalt shingles and place them on the corresponding platform respectively.

[0054] (7) If the pneumatic claw in the first position is not in working state and has not returned to its original position, and the asphalt shingles are two stuck together, the two detection devices in the first position will detect the left and right sides of the asphalt shingles at the same time. At this time, the pneumatic claw in the first position will not run, and the conveyor line will transport the asphalt shingles to the two pneumatic claws in the second position for clamping and pulling. Through the pulling and coordinating of the two work positions, the conveyor line can be operated without stopping.

[0055] (8) When the asphalt shingles stacked on the platform reach a certain thickness, the laser distance sensor detects the current stacking thickness of the asphalt shingles on the platform. Then, the cylinder moves down, driving the platform to move down, and enabling more asphalt shingles to be stacked. When the platform moves down to the point where it is detected by the full material detection device, the asphalt shingles at the bottom of the platform contact the conveyor belt of the output line. At this time, the output line runs, removing the asphalt shingles from the platform. Then the platform returns to the high position to continue the next stacking of asphalt shingles.

[0056] (9) The asphalt shingles removed by the output line can be output by the next process conveyor line, or they can be manually removed from the output line for subsequent packaging.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
