Automatic melt stream positioning device

A device for the automatic positioning of a melt stream on a first rotating disk (2) and then on at least a further rotating disk (3) of an apparatus for scattering rock wool into fibres is described, where the tank (11) discharging said melt stream is movable in a first direction (Z) parallel to the axis of the first rotating disk (2) and in a second horizontal direction (X) perpendicular to said first direction (Z), and with at least one video camera (10) placed above the flow of fibres. The optical axis of said video camera (10) and said first direction (Z) form an angle of 25 to 45 degrees in vertical direction, said video camera (10) is arranged inside a settling chamber (9) to which said rotating dicks scatter said fibres and is connected to a digitizer (15) of an electronic unit (14) in form of a computer. The electronic unit (14) further comprises an output controller (16) connected to a relay block (18) via a distribution board (17), which relay block (18) controls an alarm (21) of the video camera (10) and motors (19, 20) for moving the tank (11) for automatically positioning said melt stream (1) at a point on the first rotating disk (2), said point being controlled by images received from said one video camera (10) and said point being determined relative to said second direction as the point of intersection of a curve (6) representing the amount of waste melt and a curve (7) representing the amount of undesired cinder. Je opísané zariadenie na automatické nastavovanie prúdu taveniny na prvý rotujúci disk (2) a potom aspoň na jeden ďalší rotujúci disk (3) zariadenia na rozptyľovanie minerálnej vlny na vlákna, pričom nádrž (11) na vypúšťanie prúdu taveniny je pohyblivá v prvom smere (Z), rovnobežne s osou prvého rotačného disku (2), a v druhom horizontálnom smere (X), kolmom na prvý smer (Z), a s najmenej jednou videokamerou (10) umiestnenou nad prúdom vlákien. Optická os videokamery (10) a prvý smer (Z) zvierajú uhol 25 až 45 stupňov vo vertikálnom smere, pričom videokamera (10) je umiestnená vo vnútri usadzovacej komory (9), do ktorej rotujúce disky rozptyľujú vlákna, a je spojená s číslicovým prevodníkom (15) elektronickej jednotky (14) vo forme počítača. Elektronická jednotka (14) ďalej obsahuje výstupné kontrolné zariadenie (16), ktoré je spojené prostredníctvom rozvodovej dosky (17) s reléovým blokom (18) riadiacim signalizačné zariadenie (21) videokamery (10) a motory (19, 20) na pohybovanie nádržou (11) na automatické umiestnenie prúdu (1
