A system for monitoring ink flow from an ink storage tank to at least one ink fountain of a high-speed, web-fed printing press employing a scale for measuring the weight of the ink storage tank and comparing weight signals from the scale at successive times to determine the weight of ink consumed over the interval between readings. A pump is associated with the storage tank for pumping the ink to the fountain via coupling lines. An ink level sensor detects the level of ink in the fountain and provides an ink demand signal for operating a value means in the ink coupling line to in turn cause ink flow to the fountain so as to provide replenishment of ink thereat. With the use of plural fountains, means are provided for prioritizing delivery to the fountains so that individual ink comsumption on a per fountain basis can be determined. In this regard, the system also employs a volume sensor preferably in the form of a pump stroke positon sensor for determining incremental weight delivery per stroke.
A system for monitoring ink flow from an ink storage tank to at least one ink fountain of a high-speed web-fed printing press, said system comprising;
A system for monitoring ink flow from an ink storage tank to at least one ink fountain of a high-speed web-fed printing press, said system comprising;
A method of monitoring ink flow from an ink storage tank to at least one ink fountain of a high-speed, web-fed printing press, said method comprising the steps of, measuring the weight of the ink storage tank along with the ink stored therein so as to provide a continuation signal representative of measured weight, pumping the ink to the fountain, detecting the level of ink at the fountain and providing an ink demand signal when the level of ink in the fountain falls below a predetermined level, controlling the pumping in response to thee demand signal for causing ink to flow to the fountain comparing weight signals at successive times to determine the weight of ink consumed over the interval between readings, and measuring volume flow during the pumping.
A method of monitoring ink flow from an ink storage tank a plurality of ink fountains of a high-speed web-fed printing process comprising the steps of, measuring the weight of the ink storage tank along with any ink stored therein to provide a continuous signal representative of measured weight, pumping the ink to the fountains, comparing the weight signals at successive times to determine the weight of ink consumed from said tank over the interval between comparisons, operating delivery to only a single fountain at a time, and measuring the volume flow of ink during a single fountain delivery.
A method for monitoring the flow of material from a storage tank to a plurality of material receiving or consuming means comprising the steps of, measuring the weight of the storage tank along with any material stored therein to provide a continuous signal representative of measured weight, providing pumping means for pumping the substance to the material receiving or consuming means over a pumping interval but to deliver material to only a single receiving or consuming means at a time throughout the whole pumping interval, comparing the weight signals at successive times to determine the weight of material consumed over the interval between comparisons, and measuring the flow volume of material during a single receiving or consuming means delivery.
A system for monitoring the flow of material from a storage tank to a plurality of receiving or consuming means comprising, means for measuring the weight of the storage tank along with the material stored therein to provide a continuous signal representative of measured weight, pumping means for pumping the substance to the material receiving or consuming means to deliver material throughout a delivery interval but to only a single consuming or receiving means at a time over said whole interval, and comparing the weight signals at successive times during said pumping interval to determine the weight of material consumed over the interval between comparisons and associated with only said single receiving or consuming means,
