ABSTRACT:
An apparatus for automatically preparing dyeing solutions, comprising for respectively accommodating dye stock solutions and dye auxiliary solutions; transfer means loaded with the containers; outflow pipes incorporated with a cleaning mechanism and also equipped with a pump and a valve for causing an outflow of the dye stock solutions and the dye auxiliary solutions from the containers; receiving vessels for successively receiving the dye stock solutions and the dye auxiliary solutions from the outflow pipes; weighing means for converting, into electric signals, weight changes of the dye stock solutions and the dye auxiliary solutions which have been received in the receiving vessels; transfer means loaded with the receiving vessels; a control mechanism for continuously or intermittently opening and closing the pump and the valve by making a comparison with a predetermined value in accordance with a level of the electric signal; a dilution water outflow pipe provided with a valve for causing dilution water to flow into the receiving vessels after completely weighing the dye stock solutions and the dye auxiliary solutions; and a control mechanism for continuously or intermittently opening and closing the valve of the dilution water outflow pipe in accordance with a predetermined value.
