Fibrotor Electro-Mechanical Rotary Indexers – Feature Summary

The extensive range of rotary indexers offered by Fibro GmbH suit assembly and processing applications in diverse industries.

The Fibrotor ER and EM series tables offer fast rotary indexing of anything from tiny parts to heavy components with excellent positional accuracy and high reliability, all at a cost that is competitive with any other solution.

The cam-index mechanism used in Fibro ER and EM tables has significant advantages over other technologies including pneumatic indexers, hydraulic index tables and CNC rotary tables, making Fibrotor the leading solution for many applications.

In comparison to pneumatic or hydraulic index systems, Fibro electro-mechanical cam index tables have the following specific benefits:

  • A defined index motion with sinusoidal acceleration and deceleration is regular and dependable over time
  • Inherently smooth motion minimizes disturbance of the carried parts as well as wear and tear of the machine
  • Rapid indexing of heavy loads is possible using a surprisingly small table size
  • Cam indexing does not rely on sequencing of actuators, adjustable pressure controls, flow controls or shock absorbers
  • There is no lost time for a return stroke between indexes
  • Using simple PLC Outputs or network commands, the table is indexed in either direction at any time
  • An “In-position” signal is returned to the PLC immediately when ready for processing
  • Fibro rotary indexers are designed for reliable continuous operation in industrial environmentsDifferent types of rotary index motion are able to be simply programmed, including:
  • Repetitive indexing in a single direction at a precise angle increment
  • Index angles from 180 degrees to 1/24th of a turn or smaller
  • Bidirectional oscillation through any preset angle
  • Programmed index patterns in both directions
  • Infinitely programmable positioning of EM.NC tables.

Applications for Fibrotor ER and EM tables include:

  • Simple 180 degree loading/unloading tables that increase the efficiency of a robotic cell or machine by removing loading time from the cell cycle time.
  • Transferring fixtured parts through a multi-stage processing cycle that may include automated load/unload, assembly, pressing, machining, welding, inspection and marking stages.
  • Integration with other processes to provide precisely controlled rotary motion of a component, such as for welding or spraying operations.
