  • Roller bed for a conveyor belt system
    Patent number: 6634490
    Abstract: A roller bed that is inserted between idlers in a conveyor belt system. The roller bed includes a base plate that is oriented substantially parallel to said surface of said conveyor belt. A first side plate on a first side of the base plate is oriented at an angle to the surface of the conveyor belt to support a first side of conveyor belt and cause the first side of the conveyor belt to be angled upwards with respect to a plane of the surface. Small diameter rollers, very closely spaced, are affixed to a surface of the first side plate to support the conveyor belt and reduce friction between the side plate and the conveyor belt. A second side plate on a second side of the base plate is oriented at an angle to the surface of the conveyor belt to support a second side of the conveyor belt and cause the second side of the conveyor belt to be angled upwards with respect to the plane of the surface.

  • Roller bed for a conveyor belt system
    Patent number: 6543607
    Abstract: A bed rail assembly apparatus that is inserted between idlers in an existing conveyor system. The bed rail assembly apparatus includes a support rail oriented substantially parallel to and beneath the conveyor belt. A first bed rail assembly on a first side of the support rail and is oriented at an angle to the horizontal surface of the conveyor belt to support a first side of conveyor belt to be inclined upwards. Small diameter, closely spaced rollers, are affixed to the inclined surface of each bed rail assembly to support the inclined side of the conveyor belt and reduce friction between the rollers and the conveyor belt. A second inclined bed rail assembly on a second side of the support rail is inclined upwards to support a second inclined side of the conveyor belt. Small diameter rollers are affixed to the inclined surface of the second bed rail assembly to incline upward a second side of the conveyor belt and to reduce friction between the second inclined bed rail assembly and the conveyor belt.
