system description
PET preforms color inspection system (PSIS)
is designed to enable automated preforms color stability check directly on the production line by which preforms are being transferred from the moulding machine to holding containers.
PSIS is a machine vision system which continuously trace images of manufactured preforms on-line, analyzes these images and provides the color of manufactured preforms and their color shift.
Types of PET preforms
PET preform color of ANY existing type can be monitored by PSIS
Clear
preforms are transparent without a color.
Colored
light preforms with paint, but transparent to naked eye.
Dark
preforms that transmit natural light through one wall.
Opaque
preforms that do not transmit natural light at all.
A color discrepancy to be detected by PSIS system is assigned individually for each category, expressing it as a difference between the benchmark and non-conforming color.
Features
Complete inspection of preforms with various shape, size, color; opaque, translucent, transparent
Integrated operation with control room of the factory
Easy integration into production line
User-friendly program interface
Robust, entirely industrial solution
Express inspection on the production line
Continuous work 24/7/365
Pre-defined profiles that are suitable for inspection of common types of PET preforms
Installation
PSIS equipment is to be placed over the production line so that recently made preforms from the moulding machine would slide through PSIS equipment onto production line which then transfers preforms to holding containers.
Usually PSIS installation and configuration takes up to 2 days.
Program interface is user-friendly and simple.
Special skills or education are not required for program users.
Currently, more than 30 PSIS systems are already successfully operating at three factories in Lithuania and Ukraine.
Advantages
Maximization production line efficiency:
faster manufacturing with fewer defective products and lower labor costs.
Defect detection at the very beginning of production process:
defective preforms are immediately detect in early stage of production, thereby scaling down amount of works with obviously improper products.
Fast payback on initial investment.
