Measurement System of grain quantity stored in bag silos

摘要

It is a balance which platform is positioned on the Inner side of the Grain Bagging machines, so that it is inside the Bag during the process of filling the same. To enter the grain in the storage process, is deposited in that platform that is jointly articulated and is coupled to a load cell.At the same time, a pair of displacement Sensors, placed so as to be supported on the Outer side of the Bag, detects the Movement of the same. The Signal generated by the cell is proportional to the weight of the grain, supported on the platform, applied to a Microprocessor, having been adequate in an Amplifier with their associated Filters.This same Microprocessor are the pulses of displacement sensors. The Internal Program of the Microprocessor and these pulses when the account is equivalent to the width (d) of the heavy Platform enables the reading of the signal of the load cell.Each reading this work corresponds to the Grain Weight placed on the platform at that Instant, and is stored in a Memory area and summarized in another, so as to express the partial Weights measured on each Reading stored and the total weight, which is the sum of all Weights Program Ales.This is possible because the system described is successive elements of mass of stored Grain in Continuous form. Finally, elaborated the information is displayed in a Display positioned at the Outer part of the WRAPPING MACHINE, and can be downloaded to a PC through a RS232 Connector under Standard.
