Control system and filling method of 25L square barrel weighing type automatic filling machine

Abstract

The invention discloses a control system of a 25L square barrel weighing type automatic filling machine. The control system comprises an equipment rack, a double-layer filling barrel, a weighing scale, a material giving unit, a spray gun assembly moving unit, a double-layer filling barrel positioning unit, a positive pressure control cabinet, a pneumatic control box, a PLC and a touch screen. The invention further discloses an intelligent filling control method of the 25L square barrel weighing type automatic filling machine. The control system and the intelligent filling control method have the advantages that square barrels placed on two layers are sequentially filled one by one through multiple filling heads, the filling precision is improved, manpower is released, and meanwhile material exposure between manual switching and barrel filling is avoided. The square barrels are directly placed on a tray and arranged well, after filling is completed, the square barrels can be directly put in storage through a forklift, additional stacking work is not needed, labor force is saved, and working efficiency is improved. According to the filling method, the square barrels are positioned and placed at a time, quantitative filling is conducted on the multiple square barrels, and the filling efficiency, the safety and the automation level are improved.

Description

technical field [0001] The invention relates to a control system of a 25L square barrel weighing automatic filling machine. Background technique [0002] For the filling of liquid materials in 25L square barrels, compared with round barrels, the position of the mouth of the square barrel is relatively fixed, and it will bring some convenience to the automatic opening during filling. In actual packaging, multiple barrels of 25L barrels are usually placed on a weighing platform, and filled barrel by barrel with the filling gun head. Taking the filling of 25L square barrels in a company as an example, first place a wooden pallet on a platform scale, then place 3 rows and 4 columns of 12 square barrels on the pallet compactly, and ensure that the direction of the barrel mouth is consistent, and then manually Use a filling gun to fill barrels by weight. This kind of filling has the following problems: 1) The filling of each barrel is performed by the operator by observing the va...

Taking the filling of 25L square barrels in a company as an example, first place a wooden pallet on a platform scale, then place 3 rows and 4 columns of 12 square barrels on the pallet compactly, and ensure that the direction of the barrel mouth is consistent, and then manually Use a filling gun to fill barrels by weight. This kind of filling has the following problems: 1) The filling of each barrel is switched by the operator to the next barrel by observing the value of the weighing instrument. Accuracy control is difficult to guarantee; 2) The switching of each barrel will cause a small part of the material to leak out of the barrel, causing waste and pollution; 3) The labor intensity of the workers is relatively high, and they must always maintain a high degree of concentration and a little If there is negligence, there will be material leakage and other phenomena.
