Description

Technical Field

[0001] This utility model discloses a rejection device, belonging to the technical field of industrial automated sorting equipment, specifically relating to a dual-channel chain plate rejection device. Background Technology

[0002] In modern industrial production lines, especially in industries such as food, pharmaceuticals, and small packaging, high-speed online detection and automatic sorting of small-volume products (such as boxed, bagged, and individual items) have become crucial aspects of quality control. Currently, the industry commonly uses single-channel rejection devices to separate non-conforming (NG) products. However, this traditional rejection method has significant drawbacks: First, the single-channel structure is prone to malfunctions at high speeds, resulting in a high proportion of qualified products being mistakenly rejected (i.e., the OK carry-out ratio), directly impacting the production yield. Second, the single-channel structure has limited processing capacity, making it difficult to meet the high-capacity demands of modern production lines, thus becoming a bottleneck for capacity expansion. Third, traditional rejection devices are complex in structure and difficult to clean and maintain, especially in industries with strict hygiene requirements such as food and pharmaceuticals, where the problems of long cleaning times and high maintenance costs are particularly prominent. Furthermore, the connection between existing rejection devices and downstream production lines is not smooth enough, easily leading to product accumulation or secondary contamination. Utility Model Content

[0003] Purpose of the utility model: To provide a dual-channel chain plate rejection device to solve the problems of high false rejection rate, limited production capacity, and difficult cleaning and maintenance of existing rejection devices.

[0004] Technical solution: A dual-channel chain plate rejection device, comprising: a frame, a drive motor, a transmission system, a dual-channel conveying mechanism, and a rejection execution mechanism;

[0010] In a further embodiment, the transmission system includes four sets of precisely meshing gear mechanisms to eliminate relative displacement between the transmission rollers and the chain plates.

[0011] In a further embodiment, the chain plate has a structure that is washable from all directions.

[0012] In a further embodiment, the sensor detection system is characterized in that it is used to detect the product position in real time and predict the trajectory of NG products.

[0013] In a further embodiment, the cylinder is located below the chain plate and is used to lift the corresponding chain plate segment when a rejection signal is received.

[0014] In a further embodiment, the pressure gauge controls the cylinder to operate based on the sensor signal, and after the rejection is completed, it controls the chain plate segment to quickly reset.

[0015] In a further embodiment, an electrical control box is provided on one side of the support plate and is connected to the drive motor and the rejection actuator. The bottom of the frame is provided with several foot cups and a pressure gauge connected to the cylinder is provided on one side.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. High rejection accuracy and significantly reduced false rejection rate: The dual-channel parallel design and precise position prediction algorithm can accurately identify and reject defective products, keeping the ratio of qualified products taken out at an extremely low level, effectively improving the product yield.

[0018] 2. Significantly improved processing capacity, breaking through production capacity bottlenecks: Compared with the traditional single-channel design, the dual-channel structure nearly doubles the processing speed, effectively meeting the high-capacity requirements of modern production lines.

[0019] 3. Easy cleaning and maintenance, reducing operating costs: The chain conveyor mechanism supports all-round deep water washing, which greatly shortens the equipment cleaning time and reduces the frequency of maintenance. It is especially suitable for industries with strict hygiene requirements such as food and medicine.

[0020] 4. Precise and reliable control, stable operation: The rigid coupling design of four sets of precision meshing gears eliminates the relative displacement between the transmission roller and the chain plate, ensuring precise and reliable power transmission and accurate and error-free action.

[0021] 5. Smooth integration with the production line and good production continuity: After rejection, the chain plate quickly resets and seamlessly connects with the chain plates on both sides, ensuring smooth transport of subsequent products and maintaining the continuity of the production process.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] A dual-channel chain plate rejection device includes a frame 1, a drive motor 2, a transmission system, a dual-channel chain plate 4 conveying mechanism, and a rejection execution mechanism. The drive motor 2 transmits power to the transmission roller 3 via a synchronous belt; the transmission system includes four sets of precision-meshing gear mechanisms to achieve rigid coupling between the transmission roller 3 and the chain plate 4; the dual-channel chain plate 4 conveying mechanism consists of two parallel chain plate 4 conveying lines; the rejection execution mechanism includes a sensor detection system, a cylinder 6, and an execution controller.

[0031] In one embodiment, such as Figures 1 to 4 As shown, the sensor detection system is used to detect the product position in real time and predict the trajectory of NG products; the cylinder 6 is located below the chain plate 4 and is used to lift the corresponding segment of the chain plate 4 when a rejection signal is received; the execution controller controls the cylinder 6 to operate according to the sensor signal.

[0032] Working Principle: The drive motor 2 efficiently transmits power to the transmission roller 3 via a synchronous belt, driving it to make precise selections. The system employs a rigid coupling mechanism with four sets of precision meshing gears. This strong coupling design fundamentally eliminates any potential relative displacement between the transmission roller 3 and the chain plate 4, ensuring that the power output from the motor is accurately and reliably converted into continuous and stable linear conveying motion of the chain plate 4. When the online inspection equipment at the front end of the production line detects a non-conforming product (NG), it issues a rejection signal. At this time, the online inspection equipment reads the sensor signals on the double chain plate 4 rejection machine. Through rapid analysis and processing of these signals, it dynamically predicts the trajectory of the NG product and accurately locates its position. When the NG product is conveyed to the pre-set optimal rejection position by the chain plate 4, the online inspection equipment accurately sends an execution command to the control circuit, controlling the relay to trigger the cylinder 6. The cylinder 6 actuates, lifting the corresponding chain plate 4 upwards, thus creating a "break" on the production line (i.e., an empty space for products to fall). Because chain plate 4 is lifted, a height difference exists between this section of chain plate 4 and the rest of the production line, obstructing the progress of subsequent products. The moment a defective product reaches directly above this "break" area, the supporting chain plate 4 below is removed (creating a gap). Under the influence of gravity, the defective product loses its support and falls directly through this gap, accurately entering the waste collection device below, completing its rejection task. After the rejection action is completed, the host computer immediately issues a reset command, and the lifted chain plate 4 section precisely falls back to its original design plane position, seamlessly connecting with the chain plates 4 on both sides. At this point, the "break" area disappears, and the raised height difference barrier is also eliminated. The entire conveyor line immediately resumes normal operation, allowing subsequent products to continue to be transported smoothly, and the system seamlessly connects to the subsequent production process.

[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
