4. Equipment Description

4.1 Glass Bottle Liquid Level Inspection Unit

• Model: MT-RB-CYW-02

• Quantity: 1 set

• Production Speed: 1000 bottles/minute

• Applicable Containers: Glass bottles

• Compatible Lines: Glass bottle filling and packaging lines with capacities up to 1000 bottles/minute

• Installation Location: Positioned on a single-lane conveyor immediately downstream of the filler (liquid stratification required).

• Functionality: A high-resolution workstation camera captures real-time images of each bottle. The system analyzes the liquid level and automatically rejects bottles that fall outside the defined quality specifications.

4.2 System working principle, process and installation location

System Configuration Overview:

Station Function: The camera in Station 1 is responsible for detecting the liquid level of glass bottles.

Individual Module Detection Description:

1. When a bottle passes the positioning sensor, it detects its arrival and the control unit records the bottle ID and the current encoder value.

2. The positioning sensor notifies the camera in Station 1 to capture an image of the current liquid level of the glass bottle. After capturing the image, the image processor processes the image and transmits the result to the human-machine interface for dynamic display. The final result is then transmitted to the control unit, which uses calculations to control the rejection of unqualified bottles (with unqualified liquid levels).

3. Upon receiving the unqualified signal, the PLC notifies the rejector to reject the bottle with the corresponding ID.
