Abstract

Embodiments herein describe a DTG printing environment that uses autonomous robots to move garments between DTG processing stages (e.g., retrieval stages, pretreatment stages, printing stages, drying stages, etc.). Doing so removes the dependency of DTG printing process on the stage that consumes the most time. In one embodiment, the DTG processing stages or the autonomous robot include an actuator for moving the garment and the DTG processing stage closer together. In one embodiment, the processing stage includes a lift (e.g., an actuator) that lifts a detachable carrier from the robot on which the garment is mounted. The lift can level and rotate the detachable carrier to provide a fine alignment between the garment and the DTG processing stage. While a lift is specifically disclosed, in other embodiments, the actuator could be disposed on the robot to lift up the garment.

First claim

What is claimed is:

1. A digital printing environment, comprising:
a plurality of pretreatment stations;
a plurality of digital printing stations;
a plurality of autonomous robots configured to transport articles between the plurality of pretreatment stations and the plurality of digital printing stations,
wherein the articles are mounted on detachable carriers that are supported by the autonomous robots, and
wherein at least a first pretreatment station of the plurality of pretreatment stations is disposed on a first x-y plane and at least a first digital printing station of the plurality of digital printing stations is disposed on a second x-y plane parallel to the first x-y plane so that the first pretreatment station and the first digital printing station are vertically separated in a z direction; and
an elevator configured to move the detachable carriers, after being removed from the autonomous robots, between the first pretreatment station and the first digital printing station.

2. The digital printing environment of claim 1 , further comprising:
a second elevator configured to move the autonomous robots between the first pretreatment station and the first digital printing station.

3. The digital printing environment of claim 1 , wherein:
a first subset of the autonomous robots are disposed on the first x-y plane and configured to transport articles between the plurality of pretreatment stations and the elevator; and
a second subset of the autonomous robots are disposed on the second x-y plane and configured to transport articles between the elevator and the plurality of digital printing stations.

4. The digital printing environment of claim 1 , wherein:
the elevator comprises an actuator configured to change a relative vertical distance between an article and at least one of the first pretreatment station and the first digital printing station;
the actuator is part of a lift configured to raise the article off of the autonomous robots and in a direction towards the at least one of the first pretreatment station and the first digital printing station; and
the lift comprises alignment features configured to level the detachable carriers as the detachable carriers are raised off of the autonomous robots.

5. The digital printing environment of claim 1 , wherein:
the autonomous robots comprise:
a drive system configured to move the autonomous robots between the plurality of pretreatment stations and the plurality of digital printing stations, and
first supporting features disposed on a top side of the autonomous robots; and

the detachable carriers comprise second supporting features configured to mate with the first supporting features to mechanically interface the detachable carriers with the autonomous robots.

6. The digital printing environment of claim 1 , further comprising:
a primary controller configured to select which of the plurality of pretreatment stations and the plurality of digital printing stations is used by autonomous robots; and
a secondary controller configured to control routes used by the autonomous robots to move between the plurality of pretreatment stations and the plurality of digital printing stations selected by the primary controller.

7. The digital printing environment of claim 6 , further comprising:
a floor comprising a grid and fiducials at intersections of the grid, wherein the secondary controller is configured to use the grid and the fiducials to move the autonomous robots between the plurality of pretreatment stations and the plurality of digital printing stations selected by the primary controller.

8. The digital printing environment of claim 1 , wherein:
each detachable carrier of the detachable carriers comprises a rack configured to hold multiple levels of platens;
each level of the multiple levels of platens is vertically separated in a z direction; and
the rack is configured to move the platens between the first pretreatment station and the first digital printing station.

9. The digital printing environment of claim 1 , wherein the first x-y plane is on a first floor and the second x-y plane is on a second floor different from the first floor.

10. The digital printing environment of claim 1 , wherein the first and second x-y planes are on a same floor.

11. A digital printing environment, comprising:
a plurality of processing stages; and
a plurality of autonomous robots configured to transport articles between the plurality of processing stages,
wherein the articles are mounted on detachable carriers that are supported by the autonomous robots, and
wherein a first processing stage of the plurality of processing stages is disposed on a first x-y plane and a second processing stage of the plurality of processing stages is disposed on a second x-y plane parallel to the first x-y plane so that the first processing stage and the second processing stage are vertically separated in a z direction; and
an elevator configured to move the detachable carriers, after being removed from the autonomous robots, between the first processing stage and the second processing stage.

12. The digital printing environment of claim 11 , further comprising:
a second elevator configured to move the autonomous robots between the first processing stage and the second processing stage.

13. The digital printing environment of claim 11 , wherein:
the first processing stage comprises at least one of a pretreatment station, printing station, and drying station; and
the second processing stage comprises at least one of a folding station and packaging station.

14. A method for digital printing, comprising:
placing articles on a plurality of autonomous robots in a digital printing environment, wherein the digital printing environment comprises:
a plurality of pretreatment stations;
a plurality of digital printing stations; and
the plurality of autonomous robots,
wherein at least a first pretreatment station of the plurality of pretreatment stations is disposed on a first x-y plane and at least a first digital printing station of the plurality of digital printing stations is disposed on a second x-y plane parallel to the first x-y plane so that the first pretreatment station and the first digital printing station are vertically separated in a z direction;

moving the articles between the plurality of pretreatment stations and the plurality of digital printing stations using the plurality of autonomous robots
moving detachable carriers from the autonomous robots, wherein:
the articles are mounted on the detachable carriers; and
the detachable carriers are supported by the autonomous robots; and

moving the detachable carriers between the first pretreatment station and the first digital printing station using an elevator.

15. The method of claim 14 , further comprising moving the autonomous robots between the first pretreatment station and the first digital printing station using a second elevator.

16. The method of claim 14 , further comprising:
moving articles between the plurality of pretreatment stations and the elevator using a first subset of the autonomous robots disposed on the first x-y plane; and
moving articles between the elevator and the plurality of digital printing stations using a second subset of the autonomous robots disposed on the second x-y plane.
