Description
Technical field
The utility model relates to float glass field, is specifically related to a kind ofly measure the wide device of glass raw sheet.
Background technology
As everyone knows, since nineteen fifty-nine the first in the world bar floating process success, the float glass of float glass process moulding process is adopted just to be rapidly developed, float glass has the following advantages compared with tradition machinery abrased glass: 1, build fast, 2, reduced investment, 3, quality is good, 4, output is high, 5, cost is low, and 6, wide in variety.In a word, the appearance of floating process, is an important breakthrough of flat glass production process technology, and obtains popularization and the development of countries in the world, becomes the state-of-the-art sheet glass manufacturing process technology in the world today.
Along with the development of floating process technology and perfect, up till now, adopt floating process can produce the high-quality sheet glass that thickness is 0.5 ~ 25mm, original plate width is also all extended to more than 4m, production scale keeps the large-scale development, and at present, largest production scale reaches 1200t/d.Along with the increase of scale, the increase of Varieties, changes kind and just happens occasionally, and within one day sometimes, just may change plate several times, namely produce the glass of several different-thickness.Thus, the efficiency changing plate has just had very important impact to the benefit of enterprise.Changing in plate the significant data of reference to be exactly original plate width, and under the prerequisite that main biography speed is determined, raw sheet is wide just determines the key parameter whether this kind has changed to position.Float glass process flow process is followed successively by: glass smelting → tin groove forming → glass annealing → cold junction cutting bottom sheet, mainly measure at cold junction when measuring glass original plate width now, glass raw sheet is measured wide at cold junction, glass plate just can be measured after needing annealed operation, and the working time of glass plate in annealing kiln, also each different for its working time according to the difference of glass kind, about short then half an hour, long then more than one hour, and the time that glass runs in annealing kiln just extends cold junction and measures plate wide time, thus extend and change the plate time.Because changing plate and non-once success at every turn, the original plate width measured from cold junction makes reference, and the time cycle is oversize, therefore carry out changing plate efficiency when changing plate operation obviously to reduce, have a strong impact on output and yield rate, cause the unnecessary wasting of resources and economic loss, and then have a strong impact on company's benefit.
Also have at present and use camera to carry out the device of board width measurement at tin bath outlet by detection plain edge, it can avoid the annealing operation in ostentatious technique on the impact changing plate efficiency, but this device is obvious Shortcomings also, camera is utilized to measure plate wide, need a pair precision high, the camera that pixel is good, also need a set of data processor simultaneously, therefore a set of autonomous system is needed to carry out calculation process, moreover, tin bath outlet temperature is high, water-cooled or air cooling protection must be carried out to camera, thus make whole apparatus structure complicated, measurement range is also by the impact of installation site, general range is little, inevitably interference can be there is in camera detection process, measurement data is caused to be forbidden, daily servicing costly, the deficiency that operation easier is large.
