A new type of intelligent on-line detection instrument for lack of material in medicine board packaging machinery

Recently, the intelligent on-line detection instrument for lack of materials independently developed by Shanghai avant-garde has won the national practical new technology in 2016 This new intelligent on-line detection instrument for lack of materials has attracted the attention of pharmaceutical packaging machinery enterprises At present, the "final inspection" can not be carried out after the drug plate enters the packaging box in China In the production process, there are defects such as empty package and lack of materials Even if the probability is very small, the unqualified products will flow into the market, which will cause great losses to consumers and enterprises Therefore, it is very important to carry out automatic "final inspection" after the drug board enters the packaging box With the improvement of packaging speed and the requirements of product surface protection, non-contact and rapid detection methods are more and more valued by enterprises Current market detection methods: 1) the current use methods mainly include infrared displacement detection and mechanical contact detection The defect is that the detection accuracy is easily affected by the surface material and color of the drug plate packaging, or the surface of the drug plate is easily worn and the appearance is affected by the contact indentation 2) It can not be detected at the terminal, but only at the front end of the packaging box, which is strictly not in line with GMP requirements Only at the end of the whole packaging process, the complete and accurate test results of the product in the packaging box are complete and accurate 3) The detection speed is not suitable for high-speed packaging machine, and the detection speed is not more than 180 packages / minute Principle of the new type of intelligent on-line detection instrument for material shortage: the new type of intelligent detection instrument for material shortage is a hybrid detection structure integrated with electromagnetic wave, photoelectric and many kinds of technologies The oscillator signal of the detector enters the antenna through the isolator, forming a narrow beam, which is respectively incident to the tested part and generated by the tested part The reflected and transmitted waves enter the antenna, and use the reflection and transmission characteristics of the electromagnetic wave signal with a specific frequency to different objects By detecting the amplitude frequency and amplitude phase characteristics of the echo signal, the phenomenon of missing items in the whole package can be distinguished, and the missing items can be judged by the appropriate electrical signal output The instrument is equipped with intelligent modules such as fast data processor and self-tuning of test parameters For different volume, different thickness of aluminum, tin foil composite bags, drug boards can be accurately and quickly detected It can automatically adjust the test parameters and methods for different products on the convection water line through the self-learning process, and automatically adjust the test data without manual participation, which greatly improves the product qualification rate and production efficiency Advantages of the new type of intelligent on-line detection instrument for shortage of materials: 1) terminal detection, which directly detects the integrity of internal objects through the packaging box, is a new breakthrough in packaging detection technology It is not affected by the material, color, shape and other factors of the outer packaging object 2) Non contact detection, avoid cross contamination of packaging, do not affect the appearance and quality of products 3) The detection speed is fast, Zui is high and can detect 360 packets per minute, which is twice as fast as the current common detection method 4) Pollution free, pollution-free, complete and thorough green detection technology 5) Product cost-effective, reduce production costs 6) For example, it can replace the expensive electronic balance, and the detection speed is much higher than the electronic balance, which improves the packaging speed, greatly reduces the cost of the enterprise and improves the economic efficiency Technical parameters of the new intelligent on-line detection instrument for material shortage: detection speed: 1-360 packages / minute installation mode: up and down (or horizontal) package film width: unlimited bag length: unlimited package thickness: 1-5 plates (suitable for single plate to five plate package of capsule aluminum plastic plate.) package material: Unlimited package color: Unlimited Material of drug board: aluminum base or tin base (or other metal containing components) composite material alarm mode: sound light alarm, three indications of normal, empty bag and lack of material Output signal: relay dry contact power supply: DC 12V;
