  • the scanning units 22 are mounted at either side to the guide brackets 24, to form an effective loop around the conveyor belt 10.
  • the conveyor belt monitoring apparatus 20 is mounted to a fixed structure 26, which may be part of a conveyor belt supporting structure, by means of arms 28 which will be described in greater detail below.
  • the scanning units 22 can be seen in greater detail with reference to
  • Each scanning unit 22 has a leading roller 30 and a trailing roller 32, arranged to act as idler rollers for the conveyor belt 10.
  • the scanning units 22 are positioned on the guide brackets 24 so that, in use, the conveyor belt 10 is in engagement with both rollers 30, 32 in both scanning units 22.
  • the portion of the conveyor belt 10 between the leading roller 30 and the trailing roller 32 can thus be maintained in a taut, flat state.

  • second sensors being second ultrasonic sensors 42. These are similarly spaced from the conveyor belt 10, and are directed towards the bottom face 14 of the conveyor belt 10.
  • the second ultrasonic sensors 42 detect the distance between each sensor 42 and the bottom face 14 of the conveyor belt.
  • the upper scanning unit 22 also has a plurality of further sensors, being
  • the eddy-current sensors 44 spaced along the upper scanning unit 22 between the two guide brackets 24.

  • the eddy-current sensors 44 detect the distance between each sensor 44 and the conveyor belt core 16.
  • each of the scanning units 22 is rigidly mounted to the guide brackets 24, so that the relative positions of the first ultrasonic sensors 40, the second ultrasonic sensors 42 and the eddy-current sensors 44 are all fixed and unmoving.
  • the sensors 40, 42, 44 each have an axis of operation, and it will be understood that these axes are all parallel to each other, and perpendicular to a nominal plane representing an idealised conveyor belt surface.

  • apparatus 20 act to fix the position of the scanning units 22 relative to the lateral position of the conveyor belt 10, rather than being fixed relative to the fixed location 26. In this way, in the event of conveyor belt drift, an ultrasonic sensor 40 remains positioned above the likely location of transfer feeder chute wear.
  • the guide brackets 24 has an inner projection 50, having a flat surface 52 arranged to abut an edge 18 of the conveyor belt 10.
  • the flat surface 52 is coated in (or, indeed, the inner projection may be formed from) a low-friction material such as polytetrafluoroethylene (PTFE).
  • PTFE polytetrafluoroethylene
  • the arms 28 are jointed at either end so as to permit pivoting of the arms 28 relative to both the fixed location 26 and the guide brackets 24.
  • the arms are also slightly extendible, for instance by use of a telescoping
  • the conveyor belt monitoring apparatus 20 effectively rides or 'floats' over the conveyor belt 10 by this mechanism.
