2. Total power: about 2.4kW;

3. Control voltage: 24VDC.

4. Compressed air: minimum 4 Pa, maximum 12 Pa (the customer provides the air pipe connection between the air source and the equipment host)

Ⅳ. Equipment Introduction

1. Equipment installation plan

l Installation location: behind the filling machine, in front of or behind the inkjet printer

l Installation conditions: ensure the same single-row conveyor chain, and the single-row straight length of the conveyor chain on the production site is not less than 1.5m

l Installation progress: installation completed within 24 hours

l Chain modification: cut a 375px long guardrail gap on the straight chain to serve as the rejector of the detection equipment to reject defective products

l Equipment composition: From a macro perspective, the equipment is mainly composed of detection devices, rejection devices, power distribution cabinets, human-machine interfaces, electronic components, mechanical parts, etc.

l Placement of defective product containers: It is recommended that the buyer make a hard box and install it in combination with the defective product rejection drop position

2.Test content: LOW LEVEL OF LIQUID and WITH/WITHOUT LID

3. Detection principle

Principle: The tank body passes through the X-ray emission channel. Using the penetration principle of X-rays, products with different liquid levels form different projections at the ray receiving end and display different numerical values on the human-machine interface. At the same time, the control unit quickly accepts and processes products corresponding to different numerical values, and determines whether the liquid level of the product is qualified based on the standard parameters set by the user. If the product is confirmed to be unqualified, the detection system will automatically remove it from the conveyor line.

4. Equipment features

l Non-contact online detection, no damage to the tank body

l The counting method is an encoder, which is installed on the synchronous motor of the chain where the bad tank is located. As long as the digital number of the bad tank is recorded, the rejection effect is not affected by the line body pause or speed change, and the rejection accuracy is high

l It can automatically adapt to different production line speeds and dynamically realize detection

l The detection cabinet and control cabinet are separated, and the signals between electronic components are not interfered by electromagnetic waves, and the performance is more stable

l It adopts stainless steel shell, the main engine is sealed and designed and manufactured, anti-fog and anti-water droplets, and has strong environmental adaptability

l It automatically blocks the emission of X-rays when idle

l It adopts hardware circuit implementation and embedded operating system to ensure long-term stable operation

l It alarms with sound and light at the same time, and automatically rejects unqualified containers.

l It uses a 7-inch display touch screen to provide a simple and reliable human-machine operation interface, and it is flexible to change the tank type

l The large screen Chinese display, LED backlight LCD, clear and bright handwriting, and human-machine dialogue operation.

l It does not contain isotope radiation sources, and the radiation protection is safe and reliable.

l The core parts of Fanchi X-ray Level Inspection, such as the transmitter (Japan), receiver (Japan), human-machine interface (Taiwan), cylinder (UK Norgren), solenoid valve (US MAC), etc., are all imported with excellent performance. They can be compared with foreign brands such as US Feida, with similar detection results. There are real cases, such as Hande Wine Industry and Senli Group, with high cost performance.

5. Technical indicators 

l Production line conveyor belt speed: ≤1.3m/s

l Container diameter: 20mm~120mm (different container material density and diameter, different device selection)

l Dynamic container resolution: ±1.5mm (foam and shaking will affect the detection accuracy), about 3-5ml

l Static container resolution: ±1mm

l Unqualified container rejection rate: ≥99.99% (when the detection speed reaches 1200/minute)

l Usage conditions: Ambient temperature: 0℃~40℃, relative humidity: ≤95% (40℃), power supply: ~220V±20V, 50Hz

6. Man-machine interface

After the equipment is powered on  5S, the program automatically boot into the detection of the interface, the interface will be real-time display of the parameters of the detection of information, such as the total number of detection, the number of unqualified, real-time parameter values, bottle type information and login window.
