Description

Technical Field

[0001] The present invention relates to the technical field of asphalt shingle production, and particularly to an automatic tile collecting mechanism on an asphalt shingle production line. Background Art

[0002] Fiberglass asphalt shingles are one of the main materials commonly used for roof waterproofing, and they are attracting more and more attention. The advantages of asphalt shingles mainly include: First, diverse shapes and wide application ranges. Second, heat insulation and heat preservation. Third, light roof load, safe and reliable. Fourth, simple construction and low comprehensive cost. Fifth, durable without the worry of breakage. Sixth, diverse shapes and rich colors. The existing production method of fiberglass asphalt shingles uses fiberglass felt as the carcass, then impregnates high-quality petroleum asphalt, then covers colored mineral granules on one side, and then sprinkles release materials on the other side to make tile-shaped roofing waterproof sheets.

[0003] When the existing asphalt shingles are produced, the formed asphalt shingle products are pre-cut, segmented as a whole, and the segmented products are pre-cut into symmetrical asphalt shingle finished modules. On the current production line, the manual separation method is adopted. At the same time, the collection of asphalt shingle finished products is also carried out by manually picking them one by one and then uniformly sending them to the packaging equipment, with low efficiency and unable to realize the automatic detection of products. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an automatic tile collecting mechanism on an asphalt shingle production line, which can effectively solve the above technical problems.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an automatic tile collecting mechanism on an asphalt shingle production line, including a production line frame. The production line frame includes four areas: a separation area, a detection area, a collection area, and a packaging area. The products are conveyed between these four areas through a conveyor belt. A separation mechanism is arranged on the separation area, a detection mechanism is arranged on the detection area, and a collection mechanism is arranged on the collection area. A main conveyor is arranged on the production line frame, and an upper conveyor and a lower conveyor are separated from the main conveyor and arranged in upper and lower layers. Detection mechanisms and collection mechanisms are arranged at the ends of the upper conveyor and the lower conveyor. The separation mechanism is used to separate the segmented asphalt shingles after pre-cutting from the main conveyor into two products, and convey the separated products away through the upper conveyor and the lower conveyor respectively. The detection mechanism is used to detect products with unqualified weights and remove the unqualified products. The collection mechanism is used to collect a set number of products and automatically release the products to the conveyor belt for conveying to the packaging area after the collection is completed.

[0006] In the above technical solution, further, the separation mechanism includes a first roller pressing on the upper conveyor and a second roller pressing on the lower conveyor.

[0007] In the above technical solution, further, the detection mechanism includes a detection table that can float longitudinally, and a delay switch arranged on the detection table. A spring mechanism is arranged below the detection table; a conveying channel with a horizontal height lower than that of the detection table is arranged on one side of the detection table; when the weight of the product meets the standard, the downward floating distance of the detection table will be greater than or equal to the horizontal height difference between the detection table and the conveying channel, and one end of the product extending out of the detection table will come into contact with the conveying channel and will be conveyed to the collection area under the action of the friction force of the conveying channel; when the weight of the product does not meet the standard, it will not come into contact with the conveying channel, and the product will stay on the detection table to trigger the delay switch, and then start the automatic clamping mechanism arranged on one side to clamp it out.

[0008] In the above technical solution, further, the delay switch is an infrared sensor switch or a pressure switch, and the time for delayed start is set through an internal control board.

[0009] In the above technical solution, further, the collection mechanism includes a baffle rotatably arranged on one side of the assembly line frame. The baffle remains horizontal through a torsion spring mechanism when not under force; an electromagnet module is arranged on the other side of the assembly line frame. The electromagnet module includes a frame body, an adsorption block arranged in the frame body, a movable rod sliding on the frame body and capable of extending in and out, and a spring driving the movable rod to keep extending outwards; when the electromagnet module is not powered on, the movable rod will extend outwards and resist below the baffle to block the baffle from flipping; a release control mechanism is also arranged on one side of the assembly line frame. The release control mechanism is used to detect the quantity of products conveyed onto the baffle. When the preset quantity is reached, the electromagnet module will be powered on to enable the baffle to flip and complete the release of the collected products for falling.

[0010] In the above technical solution, further, the release control mechanism specifically includes: a ratchet wheel rotatably arranged on a rotating shaft, a first movable pawl for locking the ratchet wheel to prevent reverse return and a first spring for driving the first movable pawl to reset, a second movable pawl for driving the ratchet wheel to rotate intermittently in one direction and a second spring for resetting the second movable pawl, a driving rod for driving the second movable pawl to rotate, a conducting rod arranged on the rotating shaft, and a trigger part arranged on the pipeline frame and electrically connected to the electromagnet module circuit; the conducting rod realizes circuit wiring with an external power supply through the rotating shaft; the middle end of the driving rod is rotatably connected to the pipeline frame, the inner end is rotatably connected to the tail of the second movable pawl, and the outer end extends above the baffle; when a product enters the baffle, the convex part on the product will drive the driving rod to deflect in sequence, and then drive the ratchet wheel to rotate a first distance value. When a preset number of products are completely on the baffle, the ratchet wheel will just complete one rotation, and the conducting rod on the rotating shaft will contact the trigger part, turning on the circuit of the electromagnet module. Then, the movable rod in the electromagnet module will be adsorbed by the adsorption block into the interior, so that the baffle is no longer restricted by the movable rod. The products with a certain weight and stacked on each other will overcome the acting force of the torsion spring to make the baffle flip downward and fall onto the conveyor belt below; after discharging, the baffle will automatically return under the action of the torsion spring, and when the driving rod is driven by the next new product in the release control mechanism, the electromagnet module will be powered off again, and its movable rod will be placed below the baffle again.

[0011] In the above technical solution, further, the head of the conducting rod is an elastic electric sheet.

[0012] The beneficial effects of the present invention are as follows: The pre-cut asphalt shingles can be automatically separated by the separation mechanism; the asphalt shingle products can be detected by the detection mechanism to automatically identify unqualified products; the asphalt shingle products can be automatically collected in batches by the collection mechanism and then automatically sent to the next process after reaching the preset quantity. Generally speaking, the present invention has a higher degree of automation, can greatly reduce labor costs, and ensure production reliability. Description of the Drawings

[0019] Refer to Figures 1-4 As shown, the detailed implementation mode of the present invention is: an automatic tile collecting mechanism on an asphalt shingle production line, including a pipeline frame 1, which is divided into four areas: a separation area 2, a detection area 3, a collection area 4 and a packaging area 5. The products are conveyed between these four areas through a conveyor belt 6. A separation mechanism 7 is arranged on the separation area 2, a detection mechanism 8 is arranged on the detection area 3, and a collection mechanism 9 is arranged on the collection area 4.

[0020] A main conveyor path 10 is arranged on the pipeline frame 1, and an upper conveyor path 101 and a lower conveyor path 102 are separated from the main conveyor path 10 and arranged in upper and lower layers. There are 2 of each of the upper conveyor path 101 and the lower conveyor path 102. Detection mechanisms 8 and collection mechanisms 9 are arranged at the tails of the upper conveyor path 101 and the lower conveyor path 102. The separation mechanism 7 is used to separate the pre-cut segmented asphalt shingles from the main conveyor path 10 into two asphalt shingle finished product modules 14, and convey the separated asphalt shingle finished product modules 14 away through the upper conveyor path 101 and the lower conveyor path 102 respectively. The separation mechanism 7 includes a first roller 71 pressing on the upper conveyor path 101 and a second roller 72 pressing on the lower conveyor path 102.

[0021] The detection mechanism 8 includes a vertically floating detection table 81 and a delay switch 82 provided on the detection table 81. A spring mechanism (not shown in the figure) is provided below the detection table 81. A conveying channel 83 is provided on one side of the output end of the detection table 81. The horizontal height of the conveying channel 83 is lower than the horizontal height of the detection table 81. At the same time, the relative length of the detection table 81 is shorter than the length of the asphalt shingle finished product module 14. When the asphalt shingle finished product module 14 is conveyed to the detection table 81, due to the action of the product weight, the detection table 81 will sink. According to the different product weights, the sinking amplitude will also be different. By presetting the elastic force of the spring mechanism below the detection table 81, it can be achieved that: it is assumed that the weight of the asphalt shingle finished product module 14 should not be less than a first weight value. Products with a weight less than this first weight value are unqualified products. When the weight of the asphalt shingle finished product module 14 meets the standard, the floating distance of the detection table 81 will be greater than or equal to the horizontal height difference between the detection table 81 and the conveying channel 83. One end of the asphalt shingle finished product module 14 extending out of the detection table 81 will come into contact with the conveying channel 83 and will be conveyed to the collection area 4 under the action of the friction force of the conveying channel 83. When the weight of the asphalt shingle finished product module 14 does not meet the standard, it cannot be sent away through the conveying channel 83 and will be detained on the detection table 81. The detention time will trigger the delay switch 82, and then start the work of the automatic gripper mechanism (not shown in the figure) provided on one side. The automatic gripper will pick up the unqualified products and place them in the non-conforming product area, waiting for the worker to pick them up immediately or in batches. After being picked up, the delay switch 82 will be reset. The delay switch 82 in this embodiment can be selected as an infrared sensor switch or a pressure switch, and the delay start time can be set through the internal control board. It should be noted that the conveying of the asphalt shingle finished product module 14 has a time interval, and the time for triggering the delay switch 82 and the time for the automatic gripper to pick up the products will not interfere with the products entering the detection table 81 later. For asphalt shingles, whether the weight meets the standard is an important parameter for inspecting the products. Through the above detection mechanism, at least the products with unqualified parameters can be directly and automatically removed to improve the yield rate.

[0022] The qualified asphalt shingle finished product modules 14 will be conveyed by the conveying channel 83 to the collecting mechanism 9. The collecting mechanism 9 includes a baffle 11 arranged on the assembly line frame 1. One end of the baffle 11 in the length direction is rotatably connected to the first side of the assembly line frame 1 and is kept in a horizontal state through a torsion spring mechanism. An electromagnet module 12 is arranged on the other side of the assembly line frame 1. The electromagnet module 12 includes a frame body, an adsorption block arranged in the frame body, a movable rod 121 slidably arranged on the frame body and capable of extending in and out, and a spring for driving the movable rod 121 to keep extending outwards. When the electromagnet module 12 is not powered on, the movable rod 121 will extend outwards and resist below the baffle 11, so that the baffle 11 will not flip even when bearing weight.

[0023] In order to achieve the automatic release after the collection of the finished asphalt shingle modules 14, the collection mechanism 9 further includes a release control mechanism 13 arranged on one side of the pipeline frame 1. The release control mechanism 13 is used to detect the quantity of the finished asphalt shingle modules 14 conveyed onto the baffle 11. When the preset quantity is reached, it will energize the electromagnet module 12, enabling the baffle 11 to flip, so that several finished asphalt shingle modules 14 will collectively fall onto the conveyor belt 6 and be conveyed to the packaging area 5 together. The release control mechanism 13 specifically includes: a ratchet wheel 131 rotatably arranged on a rotating shaft 139, a first movable pawl 132 for locking the ratchet wheel 131 to prevent reverse return and a first spring 133 for driving the first movable pawl 132 to reset, a second movable pawl 134 for driving the ratchet wheel 131 to rotate intermittently in one direction and a second spring 135 for resetting the second movable pawl 134, a driving rod 136 for driving the second movable pawl 134 to rotate, a conductive rod 137 arranged on the rotating shaft 139, and a trigger part 138 arranged on the pipeline frame 1 and electrically connected to the electromagnet module 12; the conductive rod 137 realizes the circuit connection with the external power supply through the rotating shaft 139, and the head of the conductive rod 137 is an elastic electric sheet; the middle end of the driving rod 136 is rotatably connected to the pipeline frame 1, the inner end is rotatably connected to the tail of the second movable pawl 134, and the outer end extends above the baffle 11. Since each finished asphalt shingle module 14 in this embodiment has at least three convex parts 141, when the finished asphalt shingle module 14 enters the collection area 4, that is, onto the baffle 11, these convex parts 141 will successively drive the driving rod 136 to deflect, thereby driving the ratchet wheel 131 to rotate a first distance value. When the preset quantity of finished asphalt shingle modules 14 finishes entering onto the baffle 11, the ratchet wheel 131 will just complete one full rotation, and the conductive rod 137 on the rotating shaft 139 will come into contact with the trigger part 138, connecting the circuit of the electromagnet module 12. As a result, the movable rod 121 in the electromagnet module 12 will be adsorbed into the interior by the adsorption block, and the baffle 11 will no longer be restricted by the movable rod 121. The finished asphalt shingle modules 14 with a certain weight and stacked on each other will overcome the acting force of the torsion spring, causing the baffle 11 to flip downward, so that these finished asphalt shingle modules 14 will fall onto the conveyor belt 6 below and be conveyed to the packaging area 5 for overall packaging. After the blanking is completed, the baffle 11 will automatically return to its original position under the action of the torsion spring, and when the release control mechanism 13 drives the driving rod 136 to move when the next new finished asphalt shingle module 14 arrives, the electromagnet module 12 will lose power, and its movable rod 121 will be placed below the baffle 11 again.

[0024] It should be noted that in the specific production process, the outer shape structure of the asphalt shingle product module can be used to match ratchets 131 with different designs (i.e., the number of teeth of the ratchets 131). Furthermore, when a preset number of products are placed on the baffle 11, the ratchet 131 can just complete one full revolution, enabling the electromagnet module 12 to be turned on.

[0025] As mentioned above, the above are only the preferred embodiments of the present invention and do not impose any formal limitations on the present invention. Based on the technical solution of the present invention, any simple modifications, equivalent changes or decorations made shall fall within the protection scope of the present invention.
