Visual inspection method and system of characters on bag making line and bag making line

Abstract

The invention discloses a visual inspection method of characters on a bag making line. The visual inspection method includes: S1, when a film drawing assembly translates and conveys bag films from a printing station to a bag making station, once the film drawing assembly translates L, it sends a collection signal to an image collection assembly, wherein every time the film drawing assembly conveys a bag film, the corresponding translation distance is L; S2, image collection: after receiving the collection signals, the image collection assembly conducts image collection on characters on the bag films; S3: collected image analysis; when the images are unqualified, the corresponding unqualified soft bags are removed or are not filled. The invention also discloses a visual inspection system which includes an image collection assembly and an inspection assembly, wherein each time the film drawing assembly translates L, the inspection assembly ends an inspection signal to the image collection assembly so as to collect images of the characters on the bag films. The visual inspection method and system of the characters on the bag making line and the bag making line have the advantages of improving the image collection accuracy.

Description

technical field [0001] The invention mainly relates to the technical field of food and medicine packaging, in particular to a character visual detection method and system on a bag making line and a bag making line. Background technique [0002] The new version of GMP stipulates that the label of the drug must include characters such as name, specification, production batch number, production date, and expiration date. The traditional method of detecting characters such as production batch number, production date, and effective date uses manual visual inspection. This method is often subjective, and it is easy to cause missed detection and false detection due to long-term fatigue work. Once missed inspection will have a serious impact on the image of the enterprise. At present, it is also beginning to focus on the development of automated detection products to eliminate human subjectivity. For example, the soft bag character automatic detection system is used to detect the ...

Problems solved by technology

In the actual working process of the soft bag character detection system, the collection signal sent by the detection system is often inaccurate, resulting in early or delayed collection. For example, the time interval is used to send the collection signal. The instability of the components can easily cause the detected characters to be outside the range of the captured image, resulting in more misjudgments, resulting in waste of liquid medicine due to waste bag filling
