Abstract

The invention discloses a probe type loading device and a controlling method, the loading apparatus comprises a blanking tube, a resistor measure module and a controller, a first probe and a second probe distributed up and down are arranged on the blanking tube, the first probe positioned at upper portion is connected to the blanking tube, the second probe and the blanking tube are insulated, the first probe and the second probe are connected to the resistor measure module, and the resistor measure module is connected to the controller. The flow of a two stage diaphragm valve can be controlled by a first solenoid valve and a second solenoid valve, loading with two stage flow velocity of the material can be carried out, when the material in a bottle is loaded to a certain amount and contacted to the blanking tube, the material and the first probe are conducted, and continuous loading is carried out until the material and the second probe are conduced; the resistor measure module measures the resistance value between the first probe and the second probe, when the resistance value is less than a set resistance value, the two stage diaphragm valve is closed by controlling the solenoid valve, and then loading is finished.

Description

technical field [0001] The invention relates to the technical field of liquid filling, in particular to a filling control device and a control method thereof. Background technique [0002] At present, in the field of filling technology, it is necessary to control the filling volume by detecting the liquid level during filling with a probe. The existing control methods include direct detection and liquid level module detection. The detection result of the direct detection method will be affected by the foam, and the filling accuracy is not high. However, the detection method of the liquid level module is not easy to adjust, and the relevant parameters cannot be set by formula. Contents of the invention [0003] Based on this, the present invention is to provide a filling control device and a control method thereof, which can overcome the deficiencies of the prior art, and can not only set parameters through recipes, but also eliminate the influence of foam on filling accur...
