Description
Technical field
The present invention relates to the online non-contact automatic detection device of packaging production line, specifically is multifunctional bottle checker, is particularly useful for the multiple transparent or semitransparent empty bottle on the high-speed automated packaging production line is carried out the detection of quality, outward appearance and cleanliness.
Background technology
The modern industry production scale constantly enlarges, production run is continually strengthened, it is more and more higher that product quality is required, and manually-operated control can not meet the demands far away, and Automation of Manufacturing Process control and detection system become indispensable equipment.Robotization, intellectuality are a technological breakthrough of information age today and produce innovation.The core technology of intelligent online detection is--machine vision, simply, machine vision can be understood as to add to machine loads onto sighting device, or adds the machine of sighting device.Install the purpose of sighting device additional to machine, be in order to make machine have the anthropoid visual performance of class, thereby improve the robotization and the intelligent degree of machine.Because machine vision relates to a plurality of subjects, it is very difficult providing a precise definition, and benevolence person sees that the benevolence sage sees intelligence on this problem, and each one is familiar with difference.Machine vision branch of Americanized IEEE (SME) and robotization vision branch of U.S. robot industry association (RIA) become Chinese to be about the definition translation of machine vision: " machine vision is to use optical device to carry out the noncontact thoughts and feelings; obtain and explain the image of a real scene automatically, to obtain information and (/ or) control machine or process." machine vision (Machine Vision) detects a specific area of using as photoelectric technology; developed at present one have a bright future, industry that vigor is unlimited; become the focus of current new industrial research; play huge impetus in the process of industrial realization comprehensive automation, average annual growth rate surpasses 20% at present.Machine Vision Detection is widely used in numerous industries such as microelectronics, electronic product, automobile, medical treatment, printing, packing, scientific research, military affairs.It can replace manpower to detect, measure, analyze, judge and carry out Decision Control, can use in high speed situation that the vision precision the people is difficult to meet the demands or the hazardous environment that is not suitable for manpower work to some.
Beer, beverage production enterprise more and more pay attention to the quality of product at present, yet quality, outward appearance and the cleanliness of the bottle of beer, beverage production line also do not reach desired target far away at present, particularly beer industry carries out the returnable bottle that repeated washing utilizes again for beer bottle at present, in different poses and with different expressions especially, multifarious, so after bottle washing machine washing, need before the can to detect and sort out underproof bottle.The project that detects has: 1, whether bottle meets the requirements, and whether superelevation is ultralow, and is super thick, whether lid or the like is arranged, 2, whether bottleneck have damaged and crackle, 3, whether a bottle end have breakage, whether foreign matter is arranged, whether clean, 4, whether body damaged, and whether foreign matter is arranged, whether wearing and tearing exceed standard, whether clean, 5, whether alkali lye and residual water are arranged in the bottle, 6, residual wet goods organism whether in the bottle.
Traditional production line empty bottle check system is by manually finishing, and bottle is when being installed in the light test box on next door, carrier chain road, and manpower is observed, and finds that defective bottle carries out craft and takes out.This manual detection standard is fuzzy, is subjected to artificial factor to a great extent, can not keep constant standard, and accuracy of detection is low, and speed is slow.Development along with the Modern High-Speed canning line, the inferior position of human eye in detecting link protruded more, such as: owing to repeat work for a long time, the tired easily and meeting generation error that works long hours of eyes, even if these gaps all evade falling, one is rich in experienced detection employee and also can not surmounts a visual detection equipment that performance is common.Only depending on traditional artificial light to detect thus is to guarantee reliability of products, and two pith-bottlenecks of beer bottle and a bottle end be again to detect, cause the dirty wine of the part gas leakage wine and the bottle end to come into the market, bring infringement to corporate image.
And for the empty bottle checking machine that adopts on present high speed beer, the beverage production line, the checkout equipment of whole external imports of adopting, its test item is single, and it is high to supporting equipment requirements, require high to the bottle source, and hold at high price, general middle-size and small-size beer, beverage production producer are difficult to make inquiries.
