Abstract
A frame supported conveyor useful in handling baggage includes inclined flights connected to movable link plates to form an endless chain assembly. A drive arrangement located beneath the conveyor engages and moves the endless chain assembly about a closed planar path. The drive arrangement is movably mounted on the frame between an operating position in engagement with the endless chain assembly and a servicing position out of engagement with and movable away from the endless chain assembly.
Claims19
In a conveyor having a floor supported frame defining a closed planar path, an endless chain assembly adapted to move around said closed path, said conveyor employing a drive means disposed underneath and engageable with said endless chain assembly and adapted to provide motive force thereto such that said endless chain assembly will be moved about said closed planar path, the improvement comprising:
- selectively retractable mounting means disposed above the floor, rollably suspended and tiltably mounted on said frame for supporting said drive means between an operating position at which said drive means is drivingly engageable with said endless chain assembly and a servicing position at which said drive means is disengageable and movable away from said endless chain assembly for inspection and maintenance, said mounting means including rollers rotatably mounted thereon for engagement with said frame, certain of said rollers also being swingably mounted on said mounting means for engagement with said frame.
A conveyor useful for handling baggage comprising:
- a floor-supported frame defining a closed planar path;
- a plurality of pivotably connected links movable along said closed path;
- a load carrying member attached to each of said links, said links and said load carrying members forming an endless chain assembly adapted to move around said closed path;
- a plurality of pins interconnecting said links, each of said pins being provided with a cam roller;
- a drive means disposed underneath said endless chain assembly and engageable with said cam rollers to provide motive force to said endless chain assembly;
- and
- selectively retractable mounting means disposed above the floor and rollably mounted on said frame for supporting said drive means between an operating position at which said drive means is drivingly engageable with said cam rollers on said endless chain assembly and a servicing position at which said drive means is disengageable from said cam rollers and moveable away from said endless chain assembly for maintenance, said mounting means including rollers rotatably mounted thereon for engagement with said frame, certain of said rollers also being swingably mounted on said mounting means for engagement with said frame.
A conveyor useful in the handling of baggage comprising:
- a floor-supported frame defining a closed planar path;
- an endless chain assembly including a plurality of load carrying flights adapted to move around said closed path;
- a plurality of cam rollers carried by said endless chain assembly;
- a drive arrangement disposed underneath and engageable with said cam rollers on said endless chain assembly to provide motive force thereto;
- and
- selectively retractable mounting means disposed above the floor and rollably suspended to said frame for supporting said drive arrangement between an operating position at which said drive arrangement is drivingly engageable with said cam rollers on said endless chain assembly and a servicing position at which said drive arrangement is disengageable from said cam rollers and tiltable downwardly from said endless chain assembly.
