PROCESS FOR FORMING BUNDLES WITH AN EXACT AND PREDETERMINED NUMBER OF PIECES OF BARS, BY MEANS OF COUNTING UP AND FORMING BAR LAYERS DIRECTLY OVER A COOLING BED.

摘要

The present invention discloses a process for the obtention of bundles (or also low-weight sub-bundles) of counted bars, with a counting operation and layer formation comprising an exact and predetermined number of pieces, which is performed directly over a cooling bed without the need of a bar counting system. The operative technique provides for all the bars exiting every rolling mill, a cutting by a shear into a pair of pieces having a differential length relative to each other, with a subsequent sequential distribution of the sheared bars to a braking and discharging system for discharging the same onto the cooling bed so as to form a pair of transversally spaced apart bundles. The counting operation of the precise number of bars so as to conform each layer comprising an exact and predetermined number of bars, is achieved by displaying the number of cycles of movile combs when the bars are transferred from said movile combs to a layer chain conveying system by an independent comm and. The layers formed in the two conveying bands having differential lengths, are lifted and conveyed to the bundle formation location by means of unloading carts also by an independent command in a separate manner and without mixing the bars or layers together.
