[0002] The logistics industry faces numerous challenges in conveying and sorting lightweight materials, especially those packaged in film bags. The PVC conveyor belts are prone to electrostatic attraction during this process, and the lightweight nature of the materials can cause slippage between the film bags and the rollers when using a swing wheel system. This leads to overlapping and misalignment of lightweight materials, resulting in incomplete or incorrect delivery and sorting errors. Consequently, production lines experience frequent alarms, increased material sorting error rates, and decreased sorting efficiency. Summary of the Invention

[0016] Implementation, for example Figures 1 to 5As shown, the present invention relates to a flip-top sorting machine for lightweight materials, comprising a main frame 1 and a conveyor belt 2, and further comprising a flip motor 3, a crank mechanism 4, a locking mechanism 5, a locking cylinder 6, a limit photoelectric sensor 7, a positioning photoelectric sensor 8, and a discharge photoelectric sensor 9. The flip motor 3 and the crank mechanism 4 are installed at the bottom of the main frame 1, the locking mechanism 5 and the locking cylinder 6 are installed on both sides of the main frame 1, the limit photoelectric sensor 7 and the positioning photoelectric sensor 8 are respectively installed on the top surfaces of both sides of the main frame 1, and the discharge photoelectric sensor 9 is installed at the discharge port 11 of the main frame 1. The support 22 of the conveyor belt 2 is mounted on both sides of the main frame 1 via a rotating shaft 21, and the locking cylinder 6 drives the locking mechanism 5 to release or lock the rotating shaft 21 on one side of the conveyor belt 2. The flip motor 3 drives the crankshaft 41 of the crank mechanism 4 to tilt the conveyor belt 2 towards the discharge port 11 of the main frame 1.

[0017] Preferably, the crankshaft 41 of the crank mechanism 4 is connected to the center of the bottom surface of the support 22 of the conveyor belt 2 via a pin 42.

[0018] Preferably, the conveyor belt 2 is inclined at an angle of 30 degrees to the material discharge port 11 of the main frame 1.

[0019] Preferably, the conveyor belt 2 is a double-woven conveyor belt with a woven texture on its surface.

[0020] Preferred, such as Figure 4 As shown, the locking mechanism 5 includes a base 51, a swing arm 52, and a curved arm 53. The base 51 is located on the main frame 1. A notch 54 is provided on one side of the base 51 to accommodate the rotating shafts 21 on both sides of the conveyor belt 2 bracket. The two free ends of the curved arm 53 are respectively hinged to the middle part of the base 51 and the bottom end on the other side. The swing arm 52 is connected to one end of the curved arm 53 and is located at the opening position of the notch 54. The piston rod of the locking cylinder 6 is connected to the hinged end in the middle of the curved arm 53, and the extension length of the piston rod of the locking cylinder is located at the dead point position of the curved arm.

[0021] The piston rod of the locking cylinder 6 drives the hinge end in the middle of the crank arm 53, causing the crank arm 53 to retract or extend along the hinge end in the middle, thereby driving the swing arm 52 to open or close the recess 54 of the base 51. When opened, the shaft on the support side of the conveyor belt 2 can be released. When closed, the shaft on the support side of the conveyor belt 2 is locked in the recess 54 by the swing arm 52. The piston rod of the locking cylinder extends to the dead point position of the crank arm to prevent the conveyor belt from falling. When the locking cylinder retracts, the dead point structure can be opened.

[0022] The conveyor belt 2 bracket of this flip-top sorting machine is equipped with rotating shafts on both sides. The locking mechanism 5 and the locking cylinder 6 are located on both sides of the main frame 1. The locking mechanism 5 supports the rotating shafts on both sides of the conveyor belt 2 bracket, and under the action of the locking cylinder 6, the rotating shaft on one side of the conveyor belt 2 bracket can be released (depending on the drop port position set according to the thin material). At the same time, the flip motor 3 drives the crank mechanism 4 to rotate the conveyor belt 2 bracket with the rotating shaft on the other side as the fulcrum to the drop port, so that the thin material on the surface of the conveyor belt 2 can be flipped and fall to the drop port.

[0023] When this flip-top sorter is working, thin materials flow onto the conveyor belt of the sorter after the main assembly line reads the relevant information and identifies the discharge port. Once the photoelectric sensor detects the material's arrival, the locking cylinder on the dropping side opens the locking mechanism, releasing the shaft of the conveyor belt on that side. Simultaneously, the flip motor drives the crank mechanism to rotate in the opposite direction, tilting the conveyor belt 30 degrees towards the dropping side, causing the thin materials to flip and fall from the conveyor belt surface into the discharge port. After the photoelectric sensor detects the thin materials being discharged from the discharge port, the flip motor rotates forward, driving the crank mechanism to lift the conveyor belt upward and reset it. After the limit photoelectric sensor detects the conveyor belt resetting, the locking cylinder activates, pushing the locking mechanism to hold the shaft on the flip side of the conveyor belt, completing one sorting cycle for thin materials.

[0024] This tilting sorter has a simple and compact structure. It changes the original planar conveying and sorting to an inclined material drop, avoiding the adhesion of thin materials to the surface of the conveyor belt. At the same time, it adopts a double-woven conveyor belt. The woven texture of the surface has a larger gap between the packaging bags of thin materials, so there will be no electrostatic adsorption or vacuum adsorption during the conveying process. This solves the problem of poor material sliding caused by electrostatic adsorption and vacuum adsorption during the conveying and sorting process, which leads to material stacking and sorting misalignment, thus improving sorting efficiency.
