Device for detecting fill quantity of beer on line and method

Abstract

The invention discloses a device for detecting fill quantity of beer on line and a method thereof. The device comprises an electric field transmitting circuit, a transmitting polar plate, a receiving polar plate, a signal processing circuit, a detection result processing circuit and the like. The transmitting and the receiving polar plates are arranged at two sides of a bottle neck, the electric field transmitting circuit generates a high-frequency sinusoidal signal to be transmitted to the transmitting polar plate. An electric field is formed between the transmitting polar plate and the receiving polar plate. A beer bottle is arranged between the polar plates, the fill quantity of the beer influences the strength of the electric field, and the receiving polar plate and the signal processing circuit judge whether the fill quantity is qualified according to the variation of the electric field. The device realizes the detection way which is harmless to the human body and has rapid detection speed which can reach 72000 bottles per hour. The detection accuracy can reach 99 percent.

Description

Technical field [0001] The invention relates to a device and method for online detection of beer filling volume. Background technique [0002] In the current beer production line, the detection of filling volume is a very important link. There are strict requirements for filling volume. If products with unqualified filling volume enter the market, it will damage the image of the manufacturer and the interests of consumers. This must be avoided. [0003] At present, the secondary inspection of filling volume in most domestic production enterprises is done manually. Workers work monotonously, which is easy to cause visual fatigue. The speed and accuracy of inspection are difficult to meet the requirements of 36,000 bottles / hour and 72,000 bottles / hour high-speed production lines. . The domestic online filling volume inspection equipment market is basically monopolized by German and American companies and is expensive. It is of great significance to develop an online beer filling q...

Problems solved by technology

However, a small number of relevant research institutes in China mainly use machine vision to detect the filling volume in bottles, and most of the online detection equipment for beer filling volume is only in the development stage.

[0005] Gamma rays and X-rays are harmful to the human body, which limits their application; machine vision inspection solutions are expensive, and image processing technology is rarely used for filling volume inspection alone, but is mostly used for bottle inspection machine equipment inspection, and It is required that the detection container must have a certain degree of light transmission; the detection accuracy of infrared detection and ultrasonic detection technology is relatively low

In addition, after the beer is filled and sealed, there is still foam in the second detection. When the foam is converted into beer, the liquid level will rise. The above technical solutions are difficult to make a very accurate compensation for the impact of foam.
