The Explosion-proof automatic filling machine realizes the filling operation diagnosis, real-time monitoring, automatic control and so on to meet the requirements of real-time, stability and reliability of the system. Intelligent multi-functional faceplate, man-machine operation interface is simple and suitable, through the RS-422/485 interface can be rapid communication and setup. The control index of the filling weighing is mainly to judge whether the initial weighing and rechecking weighing related indexes meet the weighing requirements, and the automatic adjustment of the liquid level in the storage tank and the intermediate tank in the filling process, and the control design of the peripheral hand-held code scanner are also an important part of the control part.
020-34563445The explosion-proof automatic Filling machine conveys bottles to the production line through a motor. After the bottles are conveyed to the conveyor belt, the photoelectric sensor on the conveyor belt detects the signal of the bottles and drives the motor to move the conveyor belt forward. The bottles are transported forward along the conveyor belt. When the bottles reach the filling station, the bottles at the filling station cause the photoelectric sensor to detect the input signal, the motor of the conveyor belt stops running, and the limit sensor of the filling head is connected to start filling the bottles. When the bottle filling is completed and the limit sensor of the filling head is connected, the conveyor belt motor runs again to drive the conveyor belt forward to transport the filled bottles. When the photoelectric sensor at the capping station detects the filled bottles, the conveyor belt motor stops running. After the capping hand limit sensor is connected, the bottle capping process begins. When the bottle capping is completed and the limit sensor of the capping hand is connected, the count of the full bottle count of the finished product is increased by 1. The finished product will be transported to the next production stage along the conveyor belt. When the lower filling machine feeds the bottle again, the Liquid filling machine will complete the repetitive production process. The filling tank provided is 50L. When the volume inside the tank is less than 5L, the solenoid valve of the feeding valve will automatically open for replenishment. When the volume inside the tank is greater than 45L, the solenoid valve of the feeding valve will automatically close to stop the replenishment.
The liquid level is an analog quantity. Through A/D conversion, the 0-10V analog quantity is input and converted into a 0-27684 digital quantity, which is collected in the storage area of the PLC. In the control program, the analog input signal is first read from the PIW256, and the data type of the 16 integer is converted. Then, the digital quantity collected by the PIW256 is scaled to the actual engineering value of 0.0 to 50.0.
Combined with the virtual part of S7-PLCSIM, the WINCCV7.3 configuration software is used to configure the interface on the upper computer to realize the function of automatically monitoring the automatic filling machine. The main functions of the monitoring interface include: the canning system, which has two operation mode switching methods: manual and automatic control, finished product counting statistics, and analog quantity detection of replenishment liquid level. Configure the process screen of the tank lowering; Configure the filling process screen; Configuration and capping process screen; Configure the overall monitoring screen of the automatic filling machine and the corresponding process operation status of the upper computer
