CF118

The inspection system for checking the integrity of aluminium films

The nimax CF118 inspection system checks the integrity of aluminium films or of certain types of PVC by detecting the presence of micro-holes, tears or cracks already present in the film or produced during drawing. The nimax CF118 inspection system has the function of checking the integrity of aluminium films by detecting the presence of micro-holes, tears or cracks already present in the film or produced during drawing. The detection of a defect in the film (lack of opacity) triggers an electrical signal (relay contact) that can be used to reject the affected area. The size of the hole that triggers the device (intervention threshold) can be set with a two-decade selector on the side of the receiver and can be verified by means of dedicated calibrated micro-holes.

The Main Benefits

icona raggiungimento obbiettivi

The detection of a defect in the film (lack of opacity) triggers an electrical signal (relay contact) that can be used to reject the affected area.

icona specifiche tecniche

The size of the hole that triggers the device (intervention threshold) can be set with a two-decade selector on the side of the receiver and can be verified by means of dedicated calibrated micro-holes.

icona come funziona

A kit of three gauges can be supplied on request, with calibrated holes of 0.035, 0.050 and 0.100 mm respectively. They are useful for periodically checking the calibration of the receiver (intervention threshold – see: checking and calibration).

Inspection and Control

The solutions offered by the Inspection and Control division represent the state of the art in the main techniques for 100% quality control of products on packaging lines:

Metal detectors for the detection of foreign bodies or X-ray inspection, net weight verification with checkweighers, and verification of variable data marked or applied on the product through machine vision systems.

Technical Specifications

Composition of the unit
The unit is made up of two completely separate parts:

Illuminator
Normally mounted above the film running surface. It generates a line of high-intensity infrared light, concentrated and focused on the film by a cylindrical lens. The two lateral support blocks position it at the optimum distance. It is powered independently and has an output signal (relay) to raise an alarm in the event of faults in the light circuit.

Receiver
Normally mounted below the film running surface. It consists of a line of photosensors, placed along the reading axis, as long as the width of the film to be inspected. When it is struck by a pulse of light from the illuminator, positioned on the
upper side of the film, the electronic circuit generates an error signal corresponding to a hole or a crack. The receiver must be perfectly aligned with the illuminator and completely shielded from external light. In the case of drawn films, the format manufacturer must provide a guide support fitting the underside of the film as closely as possible.

FAQ

What are industrial inspection and control systems?

Inspection and control systems are technologies that automatically verify the quality, safety and compliance of products during production. They make it possible to detect contaminants, check weight, verify the fill level and the integrity of packs, reducing waste and preventing non-compliant products from being distributed.

What is the difference between a metal detector and an X-ray inspection system?

A metal detector detects metal contaminants only, whereas an X-ray system also identifies non-metallic contaminants such as glass, stone, calcified bone and some types of high-density plastic, as well as verifying the integrity of the product.

What is a checkweigher used for?

A checkweigher automatically checks the weight of every pack on the line, rejecting products outside tolerance and guaranteeing compliance with quality and regulatory standards.

When is it necessary to use a level control or seal control system?

Level control systems verify that every pack contains the correct quantity of product, while seal control systems make sure that packs are perfectly sealed, avoiding leaks and preserving quality and safety.

Can several inspection systems be combined on the same production line?

Yes, metal detectors, X-ray systems, checkweighers and level or seal control systems can be integrated on the same line to guarantee complete, automated quality control.
