发明名称 AUTOMATIC REPLENISHING SYSTEM OF PAINTING LIQUID
摘要 PURPOSE: To automatically replenish a prescribed quantity of a painting liquid without employing a level sensor (a liquid level meter) when the painting liquid in which the content of an adhesive, etc., is adjusted is replenished to a sub-tank from a main tank. CONSTITUTION: This system to automatically replenish a painting liquid is provided with a sub-tank T2 to store a painting liquid supplied from a main tank T1 by a pump 1, a weighing meter 3 to measure the quantity of the painting liquid stored in the sub-tank T2 , and a control part 4 to control ON/OFF operation of the pump 1 based on the detected signals from the weighing meter 3. In the case the weight W measured by the weighing apparatus 3 becomes W<=Wd (the lowest limit of the weight), the pump 1 is turned on and in the case the weight W becomes W>=Wu (the highest limit of the weight), the pump 1 is turned off and in this way the painting liquid is automatically replenished to the sub-tank T2 from the main tank T1 .
