Agr International uses a robot handling system equipped with a plastic bottle inspection system to greatly improve the efficiency of quality control

With the increase of blowing speed and the reduction of bottle weight, recycled materials are becoming an important factor affecting the production of plastic bottles
.
Regular testing and measurement of production samples is essential for quality control
.
However, due to limited personnel and equipment, the working capacity of testing laboratories can be a challenge for many production facilities and can even affect quality work
.

The Gawis AF robotic handling system from Agr International, combined with the Gawis 4D inspection system, meets the needs of processors for comprehensive testing/measurement of bottles and the limited capacity of inspection laboratories
.

Automate quality inspection to maximize test throughput

According to reports, Agr Gawis 4D is designed to automate quality inspection by combining size and thickness measurement operations (usually performed manually on a single bottle or preform) into a hands-free operation, completed in seconds
.
The robotic handling system takes the inspected plastic bottles to the next step
.

Thanks to the handling system, Gawis 4D can measure not only individual bottles but also sets of bottles or preforms
.
It can run continuously without operator intervention, maximizing test throughput while freeing lab personnel for other, more critical tasks
.

The Gawis AF robotic handling system interfaces seamlessly with the measurement system
.
At the heart of the system is a precision pick-and-place industrial robot that selects and places samples into the Gawis 4D for measurement
.

All operations are integrated

Operations are fully integrated
.
All controls and operations, including overall job setup, robotics, sample coordination, and activation and control of individual test sequences, are handled through the Gawis4D user interface
.

For sample management, samples are deposited in a multi-stage carousel equipped with rotating layers to position samples for robotic access
.
These rotating layers can be configured to accommodate bottles from single or multiple die wheels, or complete preform die sets
.

Each layer is equipped with spring-activated sample grippers that provide the robot with bottle control and positioning, while allowing the operator to quickly load
.
When testing of a single sample is complete, the robot can discard the sample or return it to the sample carousel for further analysis
.

Equipped with the Gawis AF robotic handling system, the Gawis 4D is the latest in Agr's range of high-precision bottle and preform measuring systems
.
The Gawis 4D system provides a way to perform a series of complex dimensional measurements that are fast, precise and reproducible
.

In addition, AutoJob, a patent-pending feature on Gawis 4D, simplifies job setup on the system by providing automatic identification of key completed measurements, reducing job setup time to minutes
.

The system also offers a wide range of thickness measurement options, including thickness at single or multiple discrete points anywhere on the bottle sidewall or heel, as well as performing a full vertical or horizontal (circumferential) scan to analyze preform ovality and material distribution ability
