Abstract
Storage and retrieval unit that includes a rail arrangement having a track and a flange arrangement. In a direction of gravity, the track is located below the flange arrangement. The storage and retrieval unit further includes a moving gear comprising a track roller arrangement and an array of underfriction wheels. The track roller arrangement is configured to support the moving gear on the track, and the array of underfriction wheels is arranged to engage under the flange arrangement.
Claims22
A storage and retrieval unit, comprising:
- a rail arrangement comprising a track and a flange arrangement, wherein, in a direction of gravity, the track is located below the flange arrangement;
- a moving gear comprising a track roller arrangement and an array of underpinning wheels,
- wherein the track roller arrangement is configured to support the moving gear on the track, and
- wherein the array of underpinning wheels engages under a bottom side of the flange arrangement.
A method of forming a storage and retrieval unit, comprising:
- forming a rail arrangement having flange arrangement and a track located below, with respect to a direction of gravity, the flange arrangement;
- positioning a track roller arrangement to support a moving gear on a track of the rail arrangement;
- and
- arranging an array of underpinning wheels to engage a bottom side of a flange arrangement of the rail arrangement facing the track.
A storage and retrieval unit, comprising:
- a rail arrangement comprising a track;
- a track roller arrangement movable along the track;
- a moving gear supported by the track roller arrangement;
- the rail arrangement comprising a flange arrangement;
- and
- an array of underpinning wheels arranged to engage a bottom side of the flange arrangement facing the track,
- wherein, in a direction of gravity, the track is arranged below the flange arrangement.
A storage and retrieval unit, comprising:
- a rail arrangement comprising a track, a flange arrangement and a U-shaped recess having side walls, wherein, in a direction of gravity, the track is arranged at a bottom of the U-shaped recess, which is located below the flange arrangement;
- a moving gear comprising a track roller arrangement, an array of underpinning wheels and guide rollers arranged to bear against the side walls of the U-shaped recess,
- wherein the track roller arrangement is configured to support the moving gear on the track,
- wherein the array of underpinning wheels is arranged to engage under the flange arrangement,
- wherein the bottom of the U-shaped recess forms a top side of a base plate resting on a bed of the rail arrangement, and
- the rail arrangement further comprises lateral support flanges having bottom sides that are flush with a bottom side of the base plate.
