Length Measurement of large plates

Non-contact final measurement of long plates up to approx. 10 m in length

Plates with lengths of 2 m to 6.5 m made of metal, sheet metal, wood, composite material or MDF, HDF, OSB should be automatically measured after the cut. For such measurement tasks, the non-contact, two-part length-section light scanner SLM-2 is predestined. With an accuracy in the sub-millimeter range, it provides reliable protection against both individual errors and consequential errors. Warning signals, error signals, readjustment of the cutting unit can be applied up as functions. The two-part longitudinal photoelectric proximity switch covers a measuring range of over 4.5 m between the shortest and longest material to be measured, without having to be repositioned, changed or parameterised. Target length examples: 1.5 m to 6 m or 3 m to 7.5 m.

Typical Application Data:

  • Measurement of plates after cutting, before packaging
  • Production speeds: typically up to 150 m / min
  • Problem with contact measuring devices: only sample inspection possible, accuracy: +/- 1mm/m
  • Measurement accuracy with non-contact length measurement SLM: typically 0.1mm / m
  • Amortization: 2 months, integration of the measuring system into the existing conveyor system

Material examples:

  • Metal plates, sheets, plates, composite plates
  • Wood panels, furniture panels, chipboard, OSB panels, MDF and HDF panels
  • Construction and insulation boards, plasterboard, fiberboard, insulation boards

Machines equipped with non-contact part length measurement:

  • saw line, flying saw, continuous saw
  • Guillotine, sheeter, cross divider, cutting machine, punch
  • Packaging lines, sorting lines, QA stations
