Embodiment Construction
[0026] In order to clearly illustrate the solutions in the present invention, preferred embodiments are given below and detailed descriptions are given in conjunction with the accompanying drawings.
[0027] see figure 1 , the system includes: a PLC controller that controls the filling process, the PLC controller drives the crawler controller that transmits the filled bottles, the counter records the number of filled bottles, and transmits the recorded information about the number of filled bottles to the PLC controller , when the set value is met, the PLC controller drives the push bottle controller to send the empty bottle to the filling valve on the electronic scale, and the PLC controller controls the filling.
[0028] The PLC controller includes: a counting unit connected to the main control unit, a fast valve control unit and a slow valve control unit,
[0029] The main control unit drives the crawler controller to send the filling bottle;
[0030] The counting unit wi...

The invention discloses a weighing filling system which comprises a main control unit, a counting unit, PLC controllers of a quick valve control unit and a slow valve control unit, a quick valve and a slow valve connected with a liquid storage tank; the counting unit is used for receiving the number information sent from a counter and for triggering the connected main control unit after the number information is equal to the preset value; the main control unit is used for driving the belt controller to convey filling bottles; after the trigger of the counting unit is received, the main control unit drives the bottle pushing controller to convey the filling bottles to be filled under the quick valve and the slow valve of an electronic scale, and triggers the quick valve control unit and the slow valve control unit to open the quick valve and the slow valve for filling. The quick valve is closed by the quick valve control unit after the weight value transmitted by the electric scale is judged to be equal to a first threshold value; and the slow valve is closed by the slow valve control unit after the weight value transmitted by the electric scale is judged to be equal to a second threshold value.
Description
technical field [0001] The invention relates to the technical field of automatic control, in particular to a weighing filling system. Background technique [0002] There are two main methods of liquid filling at present: weighing filling and vacuum filling. In the current actual production, weighing filling mostly adopts the method of manual weighing. In fact, it is conventional to use electronic scales to manually weigh materials. Adopt above-mentioned two kinds of methods to mainly have the following disadvantages: [0003] Manual filling: Manual filling is to manually close the filling valve when the material is close to the weight setting value. The main disadvantages of this method are as follows: [0004] (1) The filling accuracy is low, and the amount of material added needs to be adjusted repeatedly, which is easy to cause deviation; [0005] (2) Waste of labor, each person can only control one or two electronic scales for filling, and the labor efficiency is low...
