I. Equipment Parameters and Site Description
1. Project Overview
1.1 Project Name: Empty Can Detector
1.2 Project Description: Utilizing advanced machine vision inspection technology, this machine performs fully automatic, non-contact, online inspection of cans for mouth deformation, foreign matter on the can body, foreign matter inside the can, and deflated cans.
1.3 Rated Output: 1000 cans/minute
1.4 Bottle Type: Two-piece can
1.5 Product Capacity: 100mL to 600ml
2. Environmental Conditions
2.1 Optimum Altitude: 5-3000 meters above sea level;
2.2 Optimum Ambient Temperature: 5°C-40°C;
2.3 Optimum Ambient Humidity: 50-65% RH;
2.4 Factory Conditions: Parameters such as floor levelness and load-bearing capacity must meet relevant national standards and meet the requirements for normal machine operation;
2.5 Factory Storage Conditions: Upon arrival, parts and machines must be stored in a location that meets relevant national standards. During storage, proper lubrication and maintenance must be performed to prevent damage to the surface of the parts or deformation that could affect normal installation, commissioning, and operation of the machine.

4. Equipment Introduction
4.1 Empty Can Detector
Equipment Name: Empty Can Detector
Model: MT-YLG-KG-C1-01
Quantity: One set
Production Speed: 1000 cans/minute
Applicable Container: Cans
Applicable Production Line: Two-piece can packaging production lines with a production speed of no more than 1000 cans/minute
Installation Location: On the single-lane conveyor before the filler
Function Description: Uses a camera to inspect empty cans for mouth deformation, mouth tearing, V-shaped edge notches, mouth flaps, dents, foreign objects on the can body, and foreign objects inside the can, and automatically removes them online.
4.2 System working principle, process and installation location
System Configuration Overview:
1. When a can passes by a positioning sensor, it detects its arrival and records the can ID and the current encoder value through the control unit.
2. The positioning sensor notifies the camera to capture an image of the current empty 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 to prepare for the rejection of unqualified cans.
3. After receiving the unqualified signal, the PLC notifies the rejector to reject the can with the corresponding ID.
Installation location: The customer site provides a 2m straight conveyor line, with no cans squeezed in front and behind, and a 2cm gap between cans. This is very important!!!

Description (Please read carefully)
| This solution adopts a single-station single-lens inspection method, the main purpose of which is to control the can mouth (strict precision), large flat cans and large foreign objects. Since the subsequent processes include hot water washing and filling with nitrogen, small foreign objects can be washed away by hot water. Therefore, the detection accuracy of small foreign objects and small deformation of the can wall will be lower. | ||||
