US 2017/0248414 A1 · Conveyor Idler Angular Alignment Measurement Device

Abstract

A method and apparatus is disclosed for providing an indication of the perpendicularity of a conveyor belt idler with respect to a reference line known to be parallel to a direction of movement of a conveyor belt when the conveyor belt is disposed on the conveyor belt idler. An idler roller attachment structure is provided to be temporarily attached to a first idler roller having a first rotational axis. An elongated member is rotatably and axially moveably operatively attached to the idler roller attachment structure along a reference axis of rotation which is parallel to the first rotational axis. A laser, having a laser beam, is operatively attached to the elongated member, the laser beam being perpendicular to the reference axis of rotation.

A method of providing an indication of the perpendicularity of a conveyor belt idler with respect to a reference line known to be parallel to a direction of movement of a conveyor belt when the conveyor belt is disposed on the conveyor belt idler, said method comprising:

mounting a laser, having a laser beam, to a reference axis of rotation that is parallel to a first rotational axis of a first idler roller so that the laser beam can be fixed in a chosen axial position along the reference axis of rotation, at least at times, so as to maintain the laser beam perpendicular to the reference axis of rotation whereby the laser can be moved in an arc disposed in one plane perpendicular to the reference axis of rotation while the laser is maintained at the chosen axial location along the reference axis of rotation;
aligning the laser beam at a location on the reference line in a first rotary position of the laser beam by moving the laser axially along the reference axis of rotation;
and
pivoting the laser to a second rotary position corresponding to the position of a second location at or near the reference line whereby the distance from the laser beam to the reference line at the second location is the indication of perpendicularity.
