PGM-15

Miniature Roll Guide

  • #Miniature Roll Guide

Used when carrying out alignment control in the intermediate process of web transport. Used in combination with G-series controller and sensor. It is equipped with brushless motor and is superior in maintainability and achieves high response and high precision control. It is used for narrow web of 600m width or less and is suitable for alignment control of packaging machines and sanitary goods manufacturing machines.

Features

  • Brushless DC motor free of maintenance is adopted.
  • as a built-in ball screw-type microminiature actuator and is able to rotate the roll frame powerfully without rattling.
  • The turning torque of the roll frame is over 3 times that of the conventional gear-type PG-100.
  • Coupled with low backlash (less than one-tenth that of a conventional machine), it has a composition which supports the roll frame at 3 points, namely at the pivot axis and 2 points at cam follower, making it a highly rigid roll frame.
  • Roll height is 28mm lower than a conventional machine and the minimum span of the cover is 175mm (conventionally 220mm), thereby a more compact layout is made possible.
  • Because only a connector is necessary to connect PEM-type controller and PSM-type sensor, the wiring job is made simple.

See the PEM-type controller catalog for connection structure.
Other ＜Method of determining roll frame position＞
・Proximity switch is used to set center position and electronic counter-type to set stroke end position（position is set with a controller).
Automatically moves to the center when power is turned on (standard specification).
・Proximity switch for stroke end detection may be added as an optional feature.
※1．Value obtained from the swing angle of the roll frame.
（short type：±7°, long type：±4°）
※2．Tension is proportionate to the web width.
