II. Equipment Introduction

4.1 BC Can Cap Inspection Machine

Equipment Name: BC Can Cap Inspection Machine

Model: MT-YLG-PG-C4

Quantity: 1 Set

Rated Speed: 400 cans/min

Applicable Containers: Cans

Applicable Production Lines: Can and BC can packaging lines operating ≤400 cans/min

Installation Position: Single-lane conveyor, downstream of high-temperature sterilizer and air dryer

Function: Equipped with four cameras, the system performs 360° visual inspection of BC can caps and automatically rejects defective products online.

4.2 Operating Principle, Process & Installation

The inspection system utilizes synchronized vision capture and real-time image processing. Each can passes through the inspection zone where multiple cameras capture cap images from all directions. The images are analyzed by the vision processor; defective cans are identified and automatically rejected at the designated removal station. The system is installed in-line after sterilization and drying, ensuring reliable inspection without disrupting production flow.

System Configuration Overview:

Workstation Function: Four cameras perform 360° image inspection of BC can caps.

Individual Module Inspection Description:

1. A can passes the positioning sensor, which detects its arrival and records the can ID and current encoder value via the control unit.

2. The positioning sensor instructs the camera to capture an image of the current milk powder can. After capturing the image, the image processor processes the image. The image processor transmits the processing results to the human-machine interface for dynamic display and to the control unit for rejecting unqualified cans.

3. Upon receiving the unqualified signal, the PLC instructs the rejector to reject the can with the corresponding ID.
