Description

Technical Field

[0001] The present invention relates to the technical field of food packaging detection, and in particular to a packaged food sorting device equipped with a multi-view imaging processing system. Background Art

[0002] Food that has been plastic-sealed is generally tested for quality before it leaves the factory. The test items include whether there is air leakage, whether the food inside is damaged, and whether there are foreign objects or impurities inside. For foreign objects such as metal, glass, ceramics, stones, bones, plastics, etc. contained in plastic-sealed food, the general detection method and means is X-ray detection. However, foreign objects that are similar to the material of the food, or if the food in the plastic-sealed package is damaged (such as bursting, cracking, etc.), X-ray detection technology cannot detect them. At this time, this type of quality defect can only be detected by human eyes or by machine vision image detection technology.

[0003] Manual inspection with the naked eye is often labor-intensive, and after working for a long time, the human eye will become fatigued, resulting in a decrease in sorting accuracy and efficiency. The use of machine vision image inspection technology is an effective and reliable means, and it will not cause problems such as human eye fatigue and increased sorting errors due to long-term work.

[0004] For visual image detection of small or flat materials, in general, one visual camera can basically collect and obtain their key image information. However, for larger materials such as food packaging, which are usually three-dimensional, only one visual camera cannot obtain their complete feature information. In order to solve this problem, it is necessary to install multiple visual cameras and shoot the materials from multiple angles to obtain image information of the materials in different directions, and then transmit it to the data processing system for combined recognition and analysis. The more visual cameras are installed, the more complex the system is, the higher the installation accuracy requirements and the greater the difficulty of adjustment, and the more difficult the image data processing is.

[0005] At the same time, for plastic-sealed foods, the plastic cover is usually printed with patterns and other information. It is a non-transparent surface, and the characteristic information of the food cannot be detected. Only the transparent cover can detect the characteristic information of the food. After the food is plastic-sealed, it usually goes through processes such as heat shrinkage and disinfection, and the orientation of the material becomes random. Visual image detection requires that the transparent cover of the plastic-sealed packaging material can only face the visual camera to meet the collection conditions, which places high demands on the arrangement of materials.

[0006] For plastic-sealed foods such as jelly, the shape is relatively regular and the plastic cover is small, so it is easy to shape them so that the transparent cover faces the same direction. However, for plastic-sealed foods such as boiled eggs and dried tofu, they are prone to curling and deformation after plastic sealing, making shaping very difficult. If the material cannot be effectively shaped so that the transparent cover faces the detection direction, the effectiveness of visual image detection will be greatly reduced.

[0007] The purpose of the present invention is to solve the shortcomings of the prior art and provide a system that can realize the effective flipping, shaping and transmission of plastic-sealed materials, obtain complete image information of the material circumference with only two sets of cameras and reflectors for a single channel, and complete material detection, identification and sorting, thereby replacing manual sorting and improving sorting accuracy and output.

The packaged food sorting device equipped with a multi-view imaging processing system according to claim 1, characterized in that: The material conveying and separation module (120) comprises a receiving conveying line (121), a transfer module (122), a collection and identification module (123), a flipping and shaping module (124), an outer material conveying line (125), an intermediate material conveying line (126), a supporting frame (127) and a control system (128); The receiving conveyor line (121) is composed of a bracket, a conveyor belt and a driving motor, one end of which is connected to the material receiving module (130) and the other end is connected to the flipping and shaping module (124); the collection and identification module (123) and the transfer module (122) are installed on the receiving conveyor line (121); The acquisition and recognition module (123) is a camera or an image sensor, which acquires image information of the passing material and transmits it to the processing system for processing and recognition to form a processing signal; The transfer module (122) is provided with a photoelectric detection, a pushing mechanism, and a transfer slide. When the processing system gives a pushing signal and detects that the material has passed the photoelectric detection, the pushing mechanism pushes the material with the transparent surface facing upward to the transfer slide, and the material enters the outer material conveying line (125) from the transfer slide. The flipping and shaping module (124) is provided with a photoelectric detection, a flipping and shaping mechanism and a drive; when the processing system gives a flipping and shaping signal and detects that the material has passed the photoelectric detection, the flipping and shaping mechanism rotates to flip the sliding material 180 degrees so that the transparent surface faces upwards, and then slides into the intermediate material conveying line (126); The outer material conveying line (125) is composed of a bracket, a conveying belt and a driving motor, and the front docking transfer slideway (119) is used to convey the material transferred by the pushing mechanism to the transmission assembly (116) through the transfer slideway 119; The intermediate material conveying line (126) is composed of a support, a conveying belt and a driving motor, and is connected to a transfer slideway (119) at the front and a flipping and shaping mechanism at the rear. The intermediate material conveying line (126) is used to convey the material conveyed by the flipping and shaping mechanism to the transmission assembly (116) through the transfer slideway (119); The support frame (127) is a mounting base for the material conveying and separation module, and each conveying line body is mounted on the upper part; The control system (128) is a drive control and data processing center for the material conveying and separation module and is installed on a supporting frame.

9. The packaged food sorting device equipped with a multi-view imaging processing system according to claim 1, characterized in that: The feed module (130) comprises a feed hopper plate (131), a shock absorbing spring (132), a vibration motor (133), a feed installation bracket (134), and a drive module (135); the feed hopper plate (131) is installed on the upper part of the feed installation frame (134) through the shock absorbing spring (132), and the vibration motor (133) is installed on the feed hopper plate (131); the feed hopper plate (131) is provided with a guide partition, and after the material is dispersed by vibration, it passes through the guide partition and enters the receiving conveying line (121).

10. The packaged food sorting device equipped with a multi-view imaging processing system according to claim 1, characterized in that: The discharging module (140) comprises a driving motor (141), a conveying belt (142) and a discharging mounting bracket (143).
