Multi-Inspection – comprehensive quality control Optical, mechanical & rheological melt or film inspection.

POLYTEST•LINE

The COLLIN multi-inspection convinces by its wide range of application – the multi-purpose test device measures optically, mechanically and rheologically, depending on the customer requirement.

The line has a modular design. It consists of a chill roll unit, which is followed by a roller conveyor for optical and mechanical film inspection including film winder and an upstream rheological measuring section as option.

For the inspection systems (optical, IR, colour measurement, etc.), proven single components are used. The implementation into the system is centrally realized. Thus, for the user, the menu navigation is easy and gives a quick overview of the complete system. Via Ethernet, an integration into an existing line is possible.

Optical film inspection

Behind the roll unit, the film runs over the optical inspection field, consisting of illumination unit and camera. In the direct light and transmitted light area, LED strips are used. The film inspection is carried out with a 5-megapixel area camera. The inspected area achieves a dimension of 50 x 40 mm, with a pixel resolution of approx. 25 µm.

Colour & NIR measurement

As further units, a colour measurement system with colour sensor and a NIR measurement system for the detection of foreign polymer are available.

Downstream equipment

Film winder
Cutting device
Suction

Mechanical inspection

Along a measuring section, via differently running and rotating pairs of rolls, a defined elongation of the film is realized. The tensile force, necessary for that, is measured at the two rolls. Thus, online, a stress-strain-ratio can be determined.
