4.2 Automatic operation of batching scale The following window is the button window for batching: Click the "BinPara" button, and the "bin parameter" window will appear: Parameters in the window are explained as follows: Hi HZ: High speed running frequency of batching spiral conveyor Mid Hz: Medium speed running frequency of batching spiral conveyor Lo Hz: Low speed running frequency of batching spiral conveyor WT Mid: Weight of batching spiral conveyor switching from high speed to medium speed WT Lo: Weight of batching spiral conveyor switching from high speed to low speed CutOffWT: Cut-off weight of batching spiral conveyor TolWT: Tolerated overweight of each bin MaxCap: Maximum allowable kilograms of raw materials of each bin (related to the volume and proportion of raw material) The specific description is as follows taking No. 1 bin 600Kg of material as an example. Setting of parameters is shown in the above figure. Front 350Kg (600-250) of material run in 95Hz high speed. Switch to 50Hz medium speed when 250Kg of material are left. Switch to 10Hz low speed when 50Kg of material are left. Stop the spiral conveyor when 1Kg of material are left. The 1Kg of material will drop down after the spiral conveyor stops running. The system will give an alarm when the actual weight of materials exceed 601Kg, and then the spiral conveyor stops for temporary before the next action until the confirmation of operators.
