Direct falling weightlessness type material discharging machine based on neural network and controller of direct falling weightlessness type material discharging machine

Abstract

The invention discloses a direct falling weightlessness type material discharging machine based on a neural network and a controller of the direct falling weightlessness type material discharging machine. The discharging machine comprises a rack, a discharging bin, a discharging valve, a material mixing hopper, a weighing module, a falling valve, a mixed material bin and a controller; and a bin position sensor and a stirrer are installed in the discharging bin, and a mixing device is arranged in the material mixing hopper. A neural network module is adopted in the controller, the material weightlessness value is forecasted based on the material position of the discharging bin, the falling rate, the material density and the opening hole diameter of the discharging valve, and therefore theclosing time of the discharging valve is adjusted. According to the direct falling weightlessness type material discharging machine and the controller, modeling of the weighing behavior in dischargingis carried out through the neural network, the trained network can accurately forecast the falling material weightlessness value in different falling states, direct and accurate discharging can be achieved, and the machine is suitable for small-batch production; the bin position sensor and the stirrer are adopted for detecting and adjusting the material accumulation shape in the discharging bin,and fluctuation of the falling rate is reduced; and the discharging accumulation error is controlled, and the batched discharging total error is reduced.
