Description

Technical Field

[0001] This application relates to the field of packaging production inspection technology, and in particular to an automatic foreign object detection precision system. Background Technology

[0002] In the coffee production process, foreign objects mixed in with the product or its packaging is a serious quality problem. It not only affects the product's appearance but may also pose a threat to consumer health and safety. Traditional foreign object detection methods rely heavily on manual visual inspection or specialized X-ray machines. However, manual visual inspection is extremely inefficient; prolonged high-intensity work easily leads to operator fatigue, resulting in a high rate of missed detections. Furthermore, the human eye has limited accuracy, making it difficult to detect tiny foreign objects or those hidden inside the product. Specialized X-ray machines typically scan the product with X-rays of specific intensities, and products containing foreign objects are then manually removed based on the scan results, limiting the product's usability and efficiency. Utility Model Content

A photoelectric sensor, an X-ray machine, and a rejection device are sequentially arranged on the protective shell along the conveying direction of the conveyor belt.

[0006] The X-ray machine consists of an X-ray tube, a high-voltage generator, a detector system, and a current regulation module. The current regulation module is used to quickly and accurately adjust the current according to the control signal, thereby changing the intensity and density of the X-rays generated by the X-ray tube.

[0007] Preferably, the rejection device includes a cylinder mounted on a protective housing, and the movable end of the cylinder is connected to an IGBT module.

[0017] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0018] This application discloses an automated foreign object detection precision system. (Refer to...) Figure 1-3 The automatic foreign object detection precision system mainly consists of a protective shell 1, a conveyor belt 2, a guide structure 3, a photoelectric sensor 4, an X-ray machine, a rejection device, and a central controller. It can accurately detect foreign objects in the products to be inspected, ensure product quality, and protect the safety of operators.

[0019] Reference Figure 1The protective housing 1, serving as a protective barrier for the entire system, is made of lead plate or other materials with excellent X-ray shielding properties. This ensures effective X-ray shielding during the inspection process, minimizing radiation hazards and protecting the safety of operators. The internal structure of the protective housing 1 is optimized to provide a stable mounting foundation for components such as the conveyor belt 2, guide structure 3, and X-ray machine, ensuring that vibration, displacement, or other factors do not affect the inspection accuracy during operation. Simultaneously, its surface undergoes rust-proofing and anti-static treatment, significantly extending its service life, reducing daily maintenance costs, and ensuring long-term stable operation of the system.

[0020] Reference Figure 2 Conveyor belt 2 penetrates the protective shell 1 and is made of high-strength rubber or polyester fiber. The belt core material has good tensile strength, such as steel wire rope core or polyester fiber core. This allows the conveyor belt to easily withstand the weight of the product and the friction during operation, avoiding problems such as breakage and slippage during transportation, and ensuring that the product is transported smoothly and continuously. The surface of the conveyor belt is treated with anti-slip material, which effectively improves friction and further prevents the product from slipping on the conveyor belt, ensuring that the product moves forward at the predetermined speed and trajectory, laying the foundation for subsequent accurate inspection. The drive roller, driven roller, and other components of conveyor belt 2 are made of high-quality steel and undergo heat treatment processes such as quenching and tempering, which greatly improves hardness and wear resistance, making the operation of conveyor belt 2 more stable and reliable, reducing operational failures caused by component wear, and improving the overall stability and reliability of the system.

[0021] Reference Figure 1 The guide structure 3 is located on both sides of the conveyor belt 2, including guide plates 301 and adjusting screws 302. The guide plates 301 are made of aluminum alloy or stainless steel, fully utilizing the lightweight properties of aluminum alloy and the corrosion resistance of stainless steel. This allows operators to easily adjust the spacing and adapt to complex working environments, ensuring stable performance over long-term use. The adjusting screws 302 are made of high-strength alloy steel with high thread precision, ensuring a firm and reliable connection with the guide plates 301 and the protective shell 1. Fastening accessories such as nuts and washers effectively prevent loosening, guaranteeing adjustment accuracy and stability. During use, rotating the adjusting screws 302 allows for precise adjustment of the spacing of the guide plates 301, ensuring accurate matching with the product width. This ensures the product remains centered and stable during transport, preventing deviations from affecting test results and providing strong support for accurate testing.

[0022] Reference Figure 1The photoelectric sensor 4 is mounted on the protective housing 1, along the conveyor belt 2, and located in front of the X-ray machine. It enables the sensor to accurately monitor the position and passing status of the product in real time. Once the product is detected to be in place, a trigger signal is immediately sent to the central controller, which then starts the X-ray machine for inspection. This achieves automated and precise control of the inspection process, improving inspection efficiency.

[0023] Reference Figure 2 and Figure 3 The X-ray machine consists of an X-ray tube 5, a high-voltage generator 11, a detector system 10, and a current regulation module, all mounted on a protective housing 1. The X-ray tube 5 is a high-quality medical or industrial X-ray tube, producing X-rays that can clearly penetrate products, ensuring accurate detection of foreign objects. The high-voltage generator 11 uses an advanced high-frequency high-voltage generator with high voltage stability and low ripple coefficient, providing a stable and precise high voltage to the X-ray tube 5, ensuring that the X-ray tube 5 continuously and stably produces high-quality X-rays and avoiding the impact of voltage fluctuations on detection results. The detector system 10 uses a high-resolution flat panel detector or linear array detector, which can efficiently and accurately convert the X-ray signal after penetrating the product into an electrical signal and transmit it to the central controller. The current regulation module uses an IGBT module 7, which can quickly and accurately adjust the current according to the instructions sent by the central controller, thereby changing the intensity and density of the X-rays produced by the X-ray tube 5 to adapt to the detection needs of different products and ensure maximum detection accuracy.

[0024] Reference Figure 1 The rejection device is mounted on the protective housing 1, located after the X-ray machine, and includes a cylinder 9 and a pusher plate 6. The cylinder 9 is a standard type or a guided cylinder, which, upon receiving an action command from the central controller, can quickly push the abnormal product off the conveyor belt 2. The pusher plate 6 is made of stainless steel or plastic. Stainless steel has high strength, while plastic is lightweight and less likely to damage the product. The shape and size of the pusher plate 6 must be designed according to the actual situation of the product and the conveyor belt 2 to ensure that the abnormal product can be effectively pushed off the conveyor belt 2 and accurately fall into the receiving box 8 in the collection bin.

[0025] Reference Figure 1 and Figure 2A collection bin is provided on the side of the protective shell 1 away from the starting end of the conveyor belt 2, and a receiving box 8 is installed inside the collection bin. The receiving box 8 is made of plastic or metal. Plastic is lightweight and corrosion-resistant, while metal is high-strength. The volume, opening size, and other parameters of the receiving box 8 are designed according to the actual needs of the inspection operation, which facilitates the collection and cleaning of abnormal products, realizes centralized management of abnormal products, and facilitates subsequent processing.

[0026] Reference Figure 3 The central controller is mounted on the protective housing 1 and is electrically connected to the photoelectric sensor 4, the X-ray machine, and the cylinder 9. As the "brain" of the entire system, it receives the trigger signal from the photoelectric sensor 4, controls the start-up and parameter adjustment of the X-ray machine, and directs the cylinder 9 to perform rejection actions based on the detection results of the X-ray machine. This realizes the automated and intelligent operation of the system and ensures that the entire detection process is carried out efficiently and accurately.

[0027] The implementation principle of the automatic foreign object detection precision system in this application embodiment is as follows: Before starting the automatic foreign object detection precision system for product inspection, appropriate X-ray detection parameters are first set through the central controller according to the type, specifications, and characteristics of any foreign objects that may be mixed in with the product. The intensity and density of the X-rays generated by the X-ray tube 5 are then adjusted. Next, the products to be inspected are placed one by one on the conveyor belt 2. The conveyor belt 2 smoothly transports the products under the drive of the power unit. The guide structure 3 ensures the products are centered. The photoelectric sensor 4 triggers the X-ray machine for detection. If a foreign object is detected, the rejection device pushes out the abnormal product, which falls into the receiving box 8.
