The detection module, the control processing module and the rejecting apparatus are connected in order. According to the utility model, the vacuum degree of canned and bottled food and beverage container enables accurate, rapid and nondestructive testing on the production line, and the unqualified products can be removed.
Description
Technical field
The utility model relates to a kind of container vacuum tightness rapid non-destructive detecting device, relates in particular to the container vacuum tightness rapid non-destructive detecting device on the food and drink production line of pop can, vial, glass bottle packaging.
Background technology
Existing canned bottled (pop can, vial, vial) food and drink is one of food and drink that can long preservation in the daily life, for guarantee that its inner food, beverage never degenerate in the longer-term storage process, the vacuum tightness (malleation or negative pressure) in the used container must reach certain numerical value.The container of good seal will keep certain vacuum tightness after exhaust, and its meaning is: prevent that 1. the variable color of container thing, oxidation from reducing nutritive loss; 2. slow down the container inner wall corrosion, avoid fat tin of container deformation and vacation; 3. the temperature that conforms and air pressure change; 4. suppress the breeding of container aerobic microorganism.Therefore, vacuum tightness is the important indicator that detects the seal of vessel degree, guarantees its quality.
The method of the used container vacuum measurement of canned bottled food and drink has multiple, as manually beating inspection method, cover distortion ocular estimate, vacuum meter detection method, audible test method, optical method, electric vortex method, ultrasonic Detection Method, vacuum meter detection method and manually beating inspection method etc.
Manually beat the inspection method: be a kind of manual method, the hand-held woodenware of tester beats container, judges whether certain vacuum tightness according to sound, and manually beating the inspection method is to rely on the experience that detects the worker to operate, and not only efficient is low but also the reliability extreme difference.
Cover distortion ocular estimate: this method shortcoming is the same with the artificial inspection method of beating, and is a kind of primitive method that should eliminate.
The vacuum meter detection method: be a kind of destructive detection method, a kind of destructive detection method, it is that a draw point is inserted internal tank, and the outer end of needle tubing links to each other with vacuum meter, observes needle deflection direction and the reading of table, and it is qualified to judge whether.
Optical method (or claiming reflection method): parallel beam is projeced on the container cover, owing to the different convergent point differences that make catoptrical converging light of the degree of deformation of container cover, by the size of photocell detection photocurrent, and inappropriate container is rejected; But material is inhomogeneous and the measurand vibration all can bring measuring error.
Audible test method: utilize mechanical force or electromagnetic force to make the cover vibration send certain sound wave, then by pick-up unit sound wave is carried out spectrum analysis.Only be suitable for single container and detect, can not finish one group of container and detect simultaneously, and detection speed is slow, be subject to the workshop condition audio frequency and disturb, and it is bigger influenced by the cap surface thing, and practical application is restricted.
Electric vortex method: utilize the current vortex range measurement principle to measure the container cover elastic deformation amount and converse vacuum tightness again, have factor affecting precision such as measuring error correction and extraneous vibration.
In a word, the vacuum meter direct method of measurement, manually beat the low and reliability extreme difference of inspection method, cover distortion ocular estimate efficient; Audible test method, optical method use limited; Electric vortex method for the production of line measure automatically, error is big.Said method can't be used for high speed detection of dynamic on canned bottled food and drink factory encapsulation back or the preceding travelling belt that dispatches from the factory.
Along with domestic growth in the living standard, the consumer is to the pay attention to day by day of quality, being extensive use of of automatic production line, make the container vacuum tightness of canned bottled food and drink production industry detect the significantly raising that to satisfy throughput rate, manufacturing enterprise often judges that because of vacuum tightness distortion causes unnecessary the doing over again of finished product, and economic loss is bigger.
In sum, current shortage can be used for accurate, quick, the harmless checkout equipment of canned bottled food and drink container on the production line.
