Bottle Fill Level Detection

I. Equipment Specifications and Site Requirements

1. Project Overview

1.1 Project Name: Glass Bottle Liquid Level Online Inspection System

1.2 Description: This system applies advanced machine vision technology to perform fully automated, non-contact inspection of liquid level defects in glass bottles during production.

1.3 Rated Capacity: 1,000 bottles per minute (standard configuration)

1.4 Container Type: Glass bottles

1.5 Filling Volume Range: 100 mL – 1,000 mL

2. Environmental Requirements

2.1 Altitude Range: 5–3,000 meters above sea level

2.2 Operating Temperature: 5°C – 40°C

2.3 Operating Humidity: 50–65% RH

2.4 Factory Conditions: Floor flatness, load-bearing capacity, and other site parameters must comply with national standards to support normal machine operation.

2.5 Storage Conditions: Upon delivery, equipment and components must be stored in compliance with national standards. Regular lubrication and maintenance should be performed during storage to prevent part surface damage or deformation that may affect installation, commissioning, or proper operation.

3. Operating Parameters

Noise Level: ≤85 dB (actual levels vary depending on container type, machine power, and plant acoustics).

Power Supply: Connection between the customer’s main power cabinet and the equipment’s control cabinet:

Main Supply: 3 × 380V AC ±10%, 50 Hz, 3PH+N+PE

Lighting Supply: 220V AC, 50 Hz, single-phase

Total Power Consumption: ~1.0 kW

Control Voltage: 24 VDC
(Note: Non-standard voltage must be communicated in advance; equipment specifications, delivery time, and cost may be adjusted accordingly.)

4. Equipment Description

4.1 Glass Bottle Liquid Level Detector

Equipment Name: Glass Bottle Liquid Level Detector

Model: MT-RB-CYW-02

Quantity: One unit

Production Speed: 1,000 bottles per minute

Applicable Containers: Glass bottles

Suitable Lines: Glass bottle packaging lines with a maximum speed of 1,000 bottles per minute

Installation Point: On a single-lane conveyor, positioned after the filler (at the liquid level stratification section)

Function: A workstation-mounted camera captures images of bottles, analyzes liquid levels, and automatically rejects defective products online.

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.

Installation location requirements: The spacing between bottles on the conveyor line is greater than 2 cm, the conveyor line has a 2-meter-long straight track without bottle blockage, and the liquid level at the detection position is required to be stratified and a clear liquid level boundary line can be seen.
