The invention relates to a full-automatic upright quantitative packing device, which can apply the weighting, packing, transmitting and detecting on particle, sheet and abnormal materials. The invention combines the weighting device, the packing device and the weight detecting device; the feeding hopper of weighting device and the weighting hopper only have one motor for switching the material gate; the whole system uses PLC and computer as controller with one apparatus control system; the weight detecting device, according to preset weight value, detects the real packed weight and feeds back the result to said weighting device for dynamic adjustment, to make packed weight reach preset weight value; the weight detecting device first automatically adjusts itself after starting the system, then online adjusts each weighting hopper of weighting device to improve the weighting accuracy, to complete the automatic weighting, packing, weight detection and adjustment. The invention has tight structure, small size, less occupied area, easy operation, lower cost and wider application.
