Detecting material jams on deflection rollers for fabric webs

Description

Just above a deflection roller for fabric webs, a check is to be performed over their entire length (web width) to determine whether a material jam may be forming. The required sensor should have a small design and, since the check is to be performed over the entire web width, cover a large distance of up to 3 m with an unchanging, thin light beam. The initially envisaged solution based on light curtains is technically overdimensioned and is, thus, also not attractive in terms of price.

Solution

The PRKL 25B laser retro-reflective photoelectric sensor with polarization filter is used. This is an inexpensive system that is optimal for the series machines of this manufacturer since it satisfies the technical requirement: the reflection principle thereby reduces the amount of wiring, mounting is simple and fast.
