a frame; and
at least one payload carriage having
a carriage frame with drive axis and forming a payload section configured to hold one or more pickfaces, and
at least one independent degree of freedom transfer arm arranged on a first payload axis so as to move along a first payload axis transverse to the drive axis, the at least one independent degree of freedom transfer arm being disposed at least partly within the payload section;
wherein the at least one independent degree of freedom transfer arm and the payload section are configured to effect an on-the-fly sorting of the one or more pickfaces carried in the payload section.
2. The automated storage and retrieval system lift of claim 1 , wherein the at least one independent degree of freedom transfer arm is common to two or more pickfaces such that at least one independent degree of freedom transfer arm is configured to hold the two are more pickfaces adjacent one another.
3. The automated storage and retrieval system lift of claim 1 , wherein the automated storage and retrieval system lift is a high speed lift having a pickface transfer transaction rate substantially equal to a pickface transfer transaction rate of an autonomous transport vehicle transferring pickfaces to the automated storage and retrieval system lift.
4. The automated storage and retrieval system lift of claim 1 , wherein the at least one payload carriage is mounted on a mast so as to reciprocate along a length of the mast.
5. The automated storage and retrieval system lift of claim 1 , wherein the at least one independent degree of freedom transfer arm includes at least one pickface holding location arranged to hold pickfaces in at least a side by side arrangement to effect a simultaneous transfer of the pickfaces to and from the at least one independent degree of freedom transfer arm.
6. The automated storage and retrieval system lift of claim 1 , wherein the at least one independent degree of freedom transfer arm includes a plurality of pickface support tines configured for a pass through transfer of pickfaces to a pickface holding location of a storage and retrieval system.
7. The automated storage and retrieval system lift of claim 1 , wherein the drive axis comprises a common mast on which the at least one independent degree of freedom transfer arm is arranged.
8. An automated storage and retrieval system lift comprising:
a frame; and
at least one payload carriage having
a carriage frame with a drive axis and forming a payload section configured to hold one or more pickfaces, and
at least one dependent degree of freedom transfer arm arranged on a first payload axis so as to move along a first payload axis transverse to the drive axis, the at least one independent degree of freedom transfer arm being disposed at least partly within the payload section.
9. The automated storage and retrieval system lift of claim 8 , wherein the at least one independent degree of freedom transfer arm is common to two or more pickfaces such that at least one independent degree of freedom transfer arm is configured to hold the two are more pickfaces adjacent one another.
10. The automated storage and retrieval system lift of claim 8 , wherein the automated storage and retrieval system lift is a high speed lift having a pickface transfer transaction rate substantially equal to a pickface transfer transaction rate of an autonomous transport vehicle transferring pickfaces to the automated storage and retrieval system lift.
11. The automated storage and retrieval system lift of claim 8 , wherein the at least one payload carriage is mounted on a mast so as to reciprocate along a length of the mast.
12. The automated storage and retrieval system lift of claim 8 , wherein the at least one independent degree of freedom transfer arm includes at least one pickface holding location arranged to hold pickfaces in at least a side by side arrangement to effect a simultaneous transfer of the pickfaces to and from the at least one independent degree of freedom transfer arm.
13. The automated storage and retrieval system lift of claim 8 , wherein the at least one independent degree of freedom transfer arm includes a plurality of pickface support tines configured for a pass through transfer of pickfaces to a pickface holding location of a storage and retrieval system.
14. The automated storage and retrieval system lift of claim 8 , wherein the drive axis comprises a common mast on which the at least one independent degree of freedom transfer arm is arranged.
15. A method comprising:
providing a frame of an automated storage and retrieval lift;
providing at least one payload carriage having a carriage frame with a drive axis and forming a payload section configured to hold one or more pickfaces, and at least one independent degree of freedom transfer arm arranged on a first payload axis so as to move along a first payload axis transverse to the drive axis, the at least one independent degree of freedom transfer arm being disposed at least partly within the payload section;
effecting an on-the-fly sorting, with the at least one independent degree of freedom transfer arm and the payload section, of the one or more pickfaces carried in the payload section.
16. The method of claim 15 , wherein the at least one independent degree of freedom transfer arm is common to two or more pickfaces for holding the two are more pickfaces adjacent one another.
17. The method of claim 15 , wherein the automated storage and retrieval system lift is a high speed lift having a pickface transfer transaction rate substantially equal to a pickface transfer transaction rate of an autonomous transport vehicle transferring pickfaces to the automated storage and retrieval system lift.
18. The method of claim 15 , further comprising mounting the at least one payload carriage on a mast so as to reciprocate along a length of the mast.
19. The method of claim 15 , wherein the at least one independent degree of freedom transfer arm includes at least one pickface holding location arranged to hold pickfaces in at least a side by side arrangement, the method further comprising effecting a simultaneous transfer of the pickfaces to and from the at least one independent degree of freedom transfer arm.
20. The method of claim 15 , wherein the at least one independent degree of freedom transfer arm includes a plurality of pickface support tines configured for a pass through transfer of pickfaces to a pickface holding location of a storage and retrieval system.
