Description
Technical field
The present invention relates to a kind of seamless table tennis anti-pumping performances to detect sorting unit, exists for seamless table tennis anti-pumping performance
Line detects and sorting.
Background technology
Table tennis has been that numerous sports fans like as the national ball game campaign in China, and more and more people are in class
Remaining, spare time, day off participate in table tennis, also higher and higher to table tennis quality requirement with the raising of sports technology.Nothing
Seam table tennis is that have many advantages, such as, but up to the present, there are no suitable seamless table tennis is each after the new invention of the seamed ball of tradition
The effective means of item performance indicator real-time online detection, for manually to be sieved from large-tonnage product with ball needed for international top race
Choosing, inefficiency, false drop rate is high, and quality can not ensure.
According to the regulation of the existing newest T3 standards 40mm tablees tennis of International Table Tennis Federation, table tennis performance rating is table tennis items
The Comprehensive Assessment of performance indicator (including weight, circularity, bias, hardness, spring etc.) works as table tennis for anti-pumping performance requirement
It is freely fallen on special steel plate from the height of 305mm, rebound height need to be more than 240mm and be less than 265mm, can be divided into excellent
Product or Grade A table tennis can be regarded as certified products, then in conjunction with other indexs such as ball when rebound height is not less than 240mm
The Comprehensive Assessments such as weight, circularity, bias, hardness and appearance.
Following several method has been detected to table tennis anti-pumping performance according to national standard GB/T20045-2005：Light-operated inspection
Then survey method is reversely bounced by table tennis free-falling, table tennis falls can pass through certain positions twice with rebound process,
It chooses and a little places light source, there is light-sensitive element on light source opposite, and table tennis is by that can occur light-baffling phenomena, with the time being in the light twice
It is spaced approximate calculation and goes out rebound height.This method the disadvantage is that table tennis whereabouts initial velocity influences the time interval that is in the light twice,
Bring detection error；Secondly light-operated detection method can not differentiate the spring uniformity of the entire spherical surface of table tennis.Acoustic control method with it is light-operated
Method is similar, has the shortcomings that same；The table tennis ball warp inclined plate rebound of inclined plate pit type detection method, freely falling body falls into sand pit, passes through
The position for measuring sand pit calculates rebound height by empirical equation, and this method disadvantage is to be unable to real-time online measuring, limitation
It is promoted and applied；In addition camera method needs high-speed camera, expensive, and captures table tennis bound without effective ways and reach most
Image when high position.
