Description

Technical Field

[0001] The present invention relates to the technical field of waste recycling, and in particular to an unmanned production line and method for waste recycling production. Background Art

[0002] Unmanned waste recycling workshops are a new industrial model that has emerged in recent years amid the rapid development of environmental technology, artificial intelligence, the Internet of Things, and robotics. Previously, a waste recycling workshop required sorting, handling, and monitoring personnel. To reduce additional costs, however, these manual operations need to be completely replaced by intelligent systems. Specifically, intelligent sorting technology utilizes high-precision sensors (such as near-infrared spectroscopy, X-rays, and LiDAR) and computer vision (CV) systems to quickly identify the material (fabric, plastic, paper, etc.) and shape of waste. Automated handling involves robotic arms (such as Delta robots) combined with vacuum cups or flexible grippers for high-speed sorting. AGVs (Automated Guided Vehicles) or AMRs (Autonomous Mobile Robots) handle material transportation. IoT and data management utilizes IoT platforms (such as 5G and LoRa) to collect real-time equipment status and production data, enabling remote monitoring and predictive maintenance. The core goal is to improve waste recycling efficiency, reduce labor costs, and minimize environmental pollution through automation and intelligent means. Therefore, automated designs are necessary to make unmanned solid waste management a mainstream solution and promote the global transition to a circular economy. Summary of the Invention

8. The unmanned production line for waste recycling according to claim 6, characterized in that: The AGV trolley (6) includes an AGV trolley body (601). A cargo box (602) is mounted on the top of the AGV trolley body (601) and is used for automatically loading and unloading materials. The AGV trolley body (601) is equipped with a laser navigation system for locating its own position in real time and planning an optimal driving path in combination with a preset map to avoid obstacles.

9. The unmanned production line for waste recycling according to claim 6, characterized in that: The first fabric grabbing robot arm (101), the first waste paper grabbing robot arm (103), the second waste paper grabbing robot arm (104), the second fabric grabbing robot arm (105) and the third waste paper grabbing robot arm (106) are each equipped with a camera for collecting and analyzing images of waste textiles and waste paper and identifying the material and color of the waste textiles and waste paper.

10. The method for operating an unmanned production line for waste recycling according to any one of claims 7 to 9, characterized in that: The following steps are involved: S1, sorting and packaging of waste paper: A mixture of waste fabrics and paper is placed on a first conveyor belt (102). The waste on the first conveyor belt (102) is automatically grabbed according to the type of waste. A first waste paper grabbing mechanical arm (103), a second waste paper grabbing mechanical arm (104), and a third waste paper grabbing mechanical arm (106) grab the paper, complete the grabbing, and place the paper into an AGV trolley (6). After loading is completed, the AGV trolley (6) moves along a yellow paper transport path (112), a flower paper transport path (111), and a book and newspaper transport path (107) to a yellow paper baling device (114), a flower paper baling device (109), and a book and newspaper baling device (108). After unloading, the baler automatically packs the paper. S2, sorting, cleaning and packaging of waste fabrics: The waste fabric and paper mixture is on the first conveyor belt (102), and the first fabric grabbing robot arm (101) and the second fabric grabbing robot arm (105) on the first conveyor belt (102) grab the waste fabric respectively and transport it to the second conveyor belt (213) through the first connecting conveyor line (113) and the second connecting conveyor line (110) and the first transfer grabbing robot arm (115) and the second transfer grabbing robot arm (116). The waste fabric on the second conveyor belt (213) goes along the conveyor belt to the second floor and is transported to the second floor by the third fabric grabbing robot arm (201), the fourth fabric grabbing robot arm (202) and the fifth fabric grabbing robot arm. The object grasping robot arm (203) sorts the fabrics into three categories: clothing fabrics, home textile fabrics and industrial fabrics (37) and loads them onto the AGV trolley (6). The AGV trolley (6) receives instructions and moves along the clothing fabric transport path (207), the home textile fabric transport path (208) and the industrial fabric transport path (209), first arriving at the clothing fabric washing machine (204), the home textile fabric washing machine (205) and the industrial fabric washing machine (206). After washing, the fabrics are transported to the clothing fabric baling machine (210), the home textile fabric baling machine (211) and the industrial fabric baling machine (212). S3, PET bottle sorting: Green, blue and white bottles are fed by the PET bottle feeding conveyor (401), passed through the bottle blowing machine (402) and then arrive at the first storage bin (403). The first color sorter (404) selects the green bottles from the three bottles and sends them to the green bottle storage bin (405). The remaining bottles enter the second storage bin (406). The same operation is carried out. After color sorting by the second color sorter (412), the blue bottles arrive at the blue bottle storage bin (407) and the white bottles arrive at the white bottle storage bin (408). After receiving the command from the AGV car (6), they are sent to the PET bottle crushing and packaging production line (5) along the green bottle conveying path (409), the blue bottle conveying path (410) and the white bottle conveying path (411) for the next step of processing. S4, post-processing of PET bottles: The green, blue and white bottles are respectively delivered to the PET bottle feeding conveyor belt (501) in the crushing area, and are blown to the bottle discharge bin (503), crusher (504), cleaning and separation machine (505), dryer (506), hot washing pot (507), second dryer (508), rinsing tank (509), fine crusher (510) and storage and packaging barrel (511) to complete the work of PET bottle material de-labeling, crushing, cleaning, drying and fine crushing.
