Abstract

An apparatus, method and non-transitory computer readable medium for printing on a spherical object are disclosed. For example, the apparatus includes a print head, at least two wheels, wherein each one of the at least two wheels rotates around a single axis, at least one ball support coupled to a mechanical arm, wherein the at least one ball support rotates 360 degrees around and is positioned to secure the spherical object against the at least two wheels and a controller in communication with the print head and the at least two wheels to rotate the spherical object via the at least two wheels into a position to print via the print head.

First claim

What is claimed is:

1. An apparatus for printing on a spherical object, comprising:
a print head;
at least two wheels, wherein each one of the at least two wheels rotates around a single axis, wherein the at least two wheels each comprises a stack of two discs, wherein a perimeter of each one of the two discs comprises a plurality of cylindrical rollers and a plurality of connectors, wherein the plurality of cylindrical rollers and the plurality of connectors are arranged in an alternating series of a cylindrical roller and a connector;
at least one ball support coupled to a mechanical arm, wherein the at least one ball support rotates 360 degrees around and is positioned to secure the spherical object against the at least two wheels; and
a controller in communication with the print head and the at least two wheels to rotate the spherical object via the at least two wheels into a position to print via the print head.

2. The apparatus of claim 1 , wherein the print head is in a fixed position along an x-axis and a y-axis.

3. The apparatus of claim 1 , wherein the single axis of the each one of the at least two wheels is positioned at different angles.

4. The apparatus of claim 1 , wherein the at least two wheels are rotatable to position any surface of the spherical object towards the print head to receive a printing fluid.

5. The apparatus of claim 1 , wherein the two discs are arranged such that the perimeter of the alternating series of cylindrical roller and the connector of a first disc of the two discs is offset from the perimeter of the alternating series of cylindrical roller and the connector of a second disc of the two discs.

6. The apparatus of claim 1 , wherein the cylindrical rollers rotate along an axis that is perpendicular to an axis of rotation of a respective wheel.

7. The apparatus of claim 1 , wherein the cylindrical roller of a first wheel of the at least two wheels in contact with the spherical object rotates in a direction that is perpendicular to the single axis of rotation of a second wheel of the at least two wheels.

8. The apparatus of claim 1 , wherein the cylindrical roller of a first wheel of the at least two wheels in contact with the spherical object rotates in a direction that is parallel to the single axis that a first wheel of the at least two wheels rotates around.

9. The apparatus of claim 1 , wherein the cylindrical rollers comprise a plastic with a urethane coating.

10. The apparatus of claim 1 , wherein the cylindrical rollers comprise a rubber material.

11. The apparatus of claim 1 , wherein the mechanical arm is spring loaded.

12. The apparatus of claim 1 , further comprising;
a registration module that scans the spherical object to detect an origin for mapping the spherical object.

13. A method for printing on a spherical object, comprising:
receiving an image to be printed on to the spherical object;
releasing at least one mechanical arm having a ball support that rotates 360 degrees around;
detecting that the spherical object is positioned on at least two wheels, wherein each one of the at least two wheels rotates around a single axis, wherein the at least two wheels each comprises a stack of two discs, wherein a perimeter of each one of the two discs comprises a plurality of cylindrical rollers and a plurality of connectors, wherein the plurality of cylindrical rollers and the plurality of connectors are arranged in an alternating series of a cylindrical roller and a connector;
engaging the at least one mechanical arm having the ball support to secure the spherical object against the at least two wheels; and
rotating the at least two wheels to manipulate the spherical object to allow a fixed print head to print the image onto the spherical object.

14. The method of claim 13 , further comprising:
detecting an origin for mapping the spherical object to print the image.

15. The method of claim 14 , wherein the detecting comprises inserting a needle into a valve of the spherical object.

16. The method of claim 13 , wherein the rotating the at least two wheels comprises:
rotating a first wheel of the at least two wheels while a second wheel of the at least two wheels remains stationary, wherein the cylindrical roller in contact with the spherical object rotates in a direction of rotation of the first wheel.

17. An apparatus for printing on a spherical object, comprising:
a print head;
at least two wheels, wherein each one of the at least two wheels rotates around a single axis, wherein the at least two wheels each comprises a stack of two discs, wherein a perimeter of each one of the two discs comprises a plurality of cylindrical rollers and a plurality of metal connectors, wherein the plurality of cylindrical rollers and the plurality of metal connectors are arranged in an alternating series of a cylindrical roller and a metal connector such that the plurality of cylindrical rollers of a first disc of the stack of two discs is adjacent to the plurality of metal connectors of a second disc of the stack of two discs and the plurality of metal connectors of the first disc of the stack of two discs is adjacent to the plurality of cylindrical rollers of the second disc of the stack of two discs;
at least one ball support coupled to a mechanical arm positioned above the at least two wheels, wherein the at least one ball support rotates 360 degrees around and is positioned to secure the spherical object against the at least two wheels; and
a controller in communication with the print head and at least one motor coupled to the at least two wheels, wherein the controller moves the spherical object into a position to print an image onto the spherical object via the print head, wherein the spherical object is moved with the at least two wheels via operation of the at least one motor.

18. The apparatus of claim 17 , further comprising;
a registration module that scans the spherical object to detect an origin for mapping the spherical object.
