Description
Technical field
The present invention relates to a kind of seamless table tennis anti-pumping performance grouping system device, exist for seamless table tennis anti-pumping performance
Line detection and sorting.
Background technology
Table tennises have been that numerous sports fans like as the national ball game campaign of China, and increasing people is in class
Remaining, spare time, day off participate in table tennises, with the raising of sports technology, to table tennis prescription also more and more higher.No
Seam table tennis is to continue the new invention of traditional seamed ball, has many advantages, such as, but up to the present, is also suitable for seamless table tennis each
The effective means of item performance indications real-time online detection, manually will be sieved with ball for needed for international top race from large-tonnage product
Choosing, inefficiency, false drop rate is high, and quality cannot ensure.
According to the regulation of the existing up-to-date t3 standard 40mm table tennis of International Table Tennis Federation, table tennis performance rating is that table tennis is every
The Comprehensive Assessment of performance indications (including weight, circularity, bias, hardness, spring etc.), requires for anti-pumping performance, works as table tennis
Freely fall to special steel plate from the height of 305mm, bounce-back height need to be less than 265mm more than 240mm, can be divided into excellent
Product or Grade A table tennis, can be regarded as certified products when bounce-back height is not less than 240mm, then in conjunction with other indexs such as ball
The Comprehensive Assessments such as weight, circularity, bias, hardness and outward appearance.
According to GB gb/t20045-2005, table tennis anti-pumping performance being carried out with detection has following several method: light-operated inspection
Survey method passes through table tennis free-falling and then reversely upspring, table tennis fall with bounce-back process can twice through some positions,
Choose and a little place light source, there is light-sensitive element on light source opposite, and table tennis process can occur light-baffling phenomena, with the time being in the light twice
Interval approximate calculation goes out bounce-back height.This method shortcoming is the time interval that the initial velocity impact of table tennis whereabouts is in the light twice,
Bring detection error；Secondly light-operated detection method cannot differentiate the spring uniformity of the whole sphere of table tennis.Acoustic control method with light-operated
Method is similar, has the shortcomings that same；Swash plate pit detection method, the table tennis ball warp swash plate bounce-back of freely falling body falls into sand pit, passes through
The position in measurement sand pit, calculates bounce-back height by empirical equation, this method disadvantage is to be unable to real-time online measuring, limits
Its popularization and application；In addition camera method needs high-speed camera, expensive, and no effective ways seizure table tennis bound reaches
Image during high position.
