The problem that hasn't been figured out about auto-counting of reinforcing steel bar online is needed to be solved by steel company. With the improvement of accuracy of rolling, rolling negative tolerance will be inevitable. Therefore, the precision of counting of bar online is highly required. Though the manpower-counting mode can be found everywhere, but it can't fit the bar production since it's inefficient and lower level of veracity.Through a lot of investigation and research on the theory and machine of bar-counting problem, a new scheme has been figured out, also the fluid drive and engine part is designed. The scheme includes the multilevel transporting chain match a bloking-wheel, poking claw for single-sorting bars, screwing bar for orderly transporting, bar-counting by the co-working of photoelectricity sensor and OPG, lift baffle drived by hydraulic pressure for holding up and aparting.The working process of this new counting machine includes four steps. First of all, the instance of cumulate conglutination of bars is eliminted by the working of gradually accelerated transmission chains matching bloking-wheel and poking claw, meanwhile maked a certain interval between bars; And then more accurate orientated transportation is implemented by the action of transporting chain cooperating with screw bar; thirdly, bars are detected by photoelectricity sensor installed in the end of screw bar; lastly, based upon certain detecting results, transporting speed of screw bar is changed, and lift baffle begin to move so that the counting-bar is set apart from un-counting ones.For the bars overlaped are separated completely by several means cooperated, it solves the problem of counting inaccurately in real production very well. By the well done of the lift baffle, the demand of packing in certain amount is met, the precision of bar-counting device is promoted, and also the conundrum of bar-counting online is answered definitely and completely. Finally, great improvement is made in the research on counting machine for online bar.
