Abstract

Claims (38)

1. An object holder for retaining at least one object in a direct-to-object print system, the object holder comprising:

a moving frame configured to traverse a support member positioned substantially parallel to a plane formed by at least one print head of the direct-to-object print system;

at least one collapsible membrane configured to be retained within the moving frame, wherein the at least one collapsible membrane is at least partially filled with a plurality of granules, and further wherein the at least one collapsible membrane is configured to collapse at least partially around the at least one object when a volume of air is withdrawn from the at least one collapsible membrane; and

at least one inflatable bladder associated with at least one interior surface of the moving frame, wherein the at least one inflatable bladder is configured to be inflated to retain the at least one collapsible membrane within the moving frame when air is withdrawn from the at least one collapsible membrane.

2. The object holder of claim 1 , wherein the at least one inflatable bladder is attached to one or more interior surfaces of the moving frame.

3. The object holder of claim 2 , wherein the at least one inflatable bladder is fixedly attached to the moving frame.

4. The object holder of claim 2 , wherein the at least one inflatable bladder is removably attached to the moving frame.

5. The object holder of claim 1 , wherein the at least one inflatable bladder comprises at least one corrugated surface.

6. The object holder of claim 1 , wherein the at least one collapsible membrane comprises two collapsible membranes.

7. The object holder of claim 1 , wherein the moving frame is configured to be pivotable between a position substantially perpendicular to the plane formed by the at least one print head of the direct-to-object print system and a position substantially parallel to the plane formed by the at least one print head of the direct-to-object print system.

8. A direct-to-object print system for printing on at least one surface of at least one multi-dimensional object, the direct-to-object print system comprising:

at least one print head configured to eject marking material onto the at least one surface of the at least one multi-dimensional object;

a support member positioned parallel to a plane formed by the at least one print head;

an object holder comprising:

a moving frame configured to traverse the support member;

at least one collapsible membrane configured to be retained within the moving frame, wherein the at least one collapsible membrane is at least partially filled with a plurality of granules, and further wherein the at least one collapsible membrane is configured to collapse at least partially around the at least one multi-dimensional object when a volume of air is withdrawn from the at least one collapsible membrane; and

at least one inflatable bladder associated with at least one interior surface of the moving frame, wherein the at least one inflatable bladder is configured to be inflated to retain the at least one collapsible membrane within the moving frame when air is withdrawn from the at least one collapsible membrane; and

a removable base platen configured to temporarily interface with the moving frame,

wherein the removable base platen provides initial support for the at least one multi-dimensional object prior to withdrawal of the volume of air from the at least one collapsible membrane.

9. The direct-to-object print system of claim 8 , further comprising a controller configured to cause the at least one print head to eject marking material onto the at least one multi-dimensional object held by the object holder as the at least one multi-dimensional object passes the at least one print head.

10. The direct-to-object print system of claim 8 , further comprising a pump fluidly coupled to the at least one collapsible membrane, wherein the pump is configured to withdraw a volume of air from the at least one collapsible membrane to cause the at least one collapsible membrane to collapse and for the plurality of granules within the at least one collapsible membrane to at least partially conform to a shape of the at least one multi-dimensional object.

11. The direct-to-object print system of claim 8 , further comprising a plurality of datum pins associated with the removable base platen, the plurality of datum pins configured to support the at least one multi-dimensional object.

12. The direct-to-object print system of claim 11 , wherein the removable base platen further comprises a plurality of slots formed therethrough, and further wherein the plurality of datum pins are configured to be selectively movable within the plurality of slots.

13. The direct-to-object print system of claim 11 , wherein each of the plurality of datum pins are tapered.

14. The direct-to-object print system of claim 8 , wherein the moving frame of the object holder comprises at least one open side, and further wherein the removable base platen is configured to temporarily interface with the moving frame about the at least one open side.

15. The direct-to-object print system of claim 8 , wherein the at least one inflatable bladder comprises at least one inflatable bladder associated with four interior surfaces of the moving frame.

16. A method for printing on at least one multi-dimensional object, the method comprising:

providing an object holder, the object holder comprising a moving frame and at least one inflatable bladder associated with one or more surfaces of the moving frame;

placing the at least one multi-dimensional object within the moving frame of the object holder;

inserting at least one granule-filled collapsible membrane within the moving frame and at least partially around at least one surface of the at least one multi-dimensional object;

applying a vacuum on the at least one granule-filled collapsible membrane;

applying pressurized air to the at least one inflatable bladder to provide a clamping force on the at least one granule-filled collapsible membrane;

transporting the object holder past at least one print head; and

printing directly on at least one surface of the at least one multi-dimensional object held within the object holder.

17. The method of claim 16 , further comprising providing a base platen having a plurality of movable datum pins thereon and temporarily associating the base platen with the moving frame in order to support the at least one multi-dimensional object within the moving frame.

18. The method of claim 17 , further comprising securing the plurality of movable datum pins on the base platen around at least one surface of at least one multi-dimensional object.

19. The method of claim 17 , further comprising removing the moving frame from the base platen before transporting the object holder past the at least one print head.

20. The method of claim 17 , further comprising returning the moving frame to the base platen after printing directly on at least one surface of the at least one multi-dimensional object.
