Filling machine with quantity control

Description

This function block automates the entire process of a bottling plant – from the conveyor belt to precise quantity monitoring at the filling valve. The integrated safety logic ensures that everything is immediately and safely stopped in the event of an alarm. The SCL code is immediately executable in the Siemens TIA Portal and is suitable for applications in the beverage, pharmaceutical, or chemical industries.

Note: All modules are designed exclusively as a learning and optimization basis and are not approved for live operation. System modules, in particular, must be finally tested and commissioned by qualified personnel before productive use.

How it works

It all starts with a safety check: Press the emergency stop or stop button – and the system shuts down. The conveyor belt stops, the filling valve closes, and the process returns to step 0.

In automatic mode, the cycle runs as follows:

1. Start button pressed? ⇒ The conveyor belt brings a bottle under the filling valve.
2. Bottle detected? ⇒ The belt stops, the valve opens.
3. Fill level reached? ⇒ The valve closes, the belt starts running again.
4. Bottle removed? ⇒ The cycle starts again.

To ensure that each new filling is measured correctly, the control system automatically sets a reset signal for the actual quantity with each new filling process.

Technical details

• State control : via integer step counter (FSM)
• Safety logic : Emergency stop and stop buttons have highest priority
• Fill level monitoring : Analog comparison between actual and target value
• ResetActualQuantity : is only set during the filling step
• Outputs : provide TRUE/FALSE for conveyor belt, valve and HMI display

Everything is clear, understandable and modular – ideal for practical use.

Possible applications

Perfect for:

• Beverage and food bottling
• Pharmaceutical production lines
• Demonstration and laboratory facilities

Thanks to the structured logic, the module can be easily adapted to different bottle sizes and filling quantities .
