Traversing units  / EN

The MRP scanner for traversing measuring is designed as a torsional stiff welded steel construction with raceway shaft guide on precision shafts. This robust and durable design ensures problem-free operation in the demanding environment of a paper mill.
Depending on their requirements, operators can choose from various measuring frame variants.

 

 

 

Characteristics / Features

 

The measuring frame can be rotatably hung up. The mounting is performed by using frontal spigots. The spigots with their shell carriers act as transfer point. The stators and all possibly related concrete chiselling works are not included in the scope of the MRP delivery.

  • Guide rails (O1 and O2) or hardened chrome plated steel round shafts with a diameter of 40 mm, mounted on adjustable bridges every 240mm for O1 and O2 or every 400 mm for O3.
  • Three-phase motor 0.25 KW; Standard motor with hollow shaft. Control via Siemens frequency con-verter
  • Standard incremental encoder as position encoder with Profibus interface. The resolution of the ro-tary encoder is 0.075 mm
  • Adaptation to paper web angle by rotating the measuring trolley or the frame
  • Fibreglass-reinforced, non-stretchable toothed belt
  • Ratchetting clutches for separating the upper from the lower measuring system platform and for the purpose of anti-crushing protection.
  • Measuring slide as recirculating ball bearing carriage (O1 and O2), or as a double T-beam guided across 24 ball bearings.
  • Long-lasting energy is supplied through synthetic multi-chamber link chains with shielded round ca-bles and air/water hoses
  • Dust cover for O2 and O3 by means of a continuously driven masking tape made of woven synthet-ic.
  • A powder coating surface treatment is optionally available.
  • Internally ventilated variants are optionally available.
  • Innenbelüftete Varianten optional erhältlich.
  • Measuring system boards for multiple sensors
  • Fan housing including temperature measuring mounted on the measuring system board.
  • Automated web edge detection
