Abstract

A system for printing images on an object, the system including, a housing, a rod driven by a first motor, an object rotating subsystem positioned about the rod and arranged for reciprocal movement, an object rotating subsystem that includes a spindle and a second motor connected to the spindle and configured to rotate the object in a first rotational direction or a second rotational direction. The system further including a vacuum source connected to the spindle, a plurality of printheads, a curing lamp, and a controller connected to the plurality of printheads, the first motor, the second motor, the curing lamp, the controller configured to operate the first motor, the second motor, the plurality of printheads, and the curing lamp, wherein the plurality of printheads are configured to eject a first marking material onto the object and the second motor rotates the object in the first or second rotational direction.

Claims

1. A system for printing images on an object, the system comprising:

a housing;

a rod driven by a first motor;

an object rotating subsystem positioned about the rod and arranged for reciprocal movement, the object rotating subsystem comprising;

a spindle; and

,

a second motor operatively connected to the spindle and configured to rotate the object in a first rotational direction and/or a second rotational direction;

a vacuum source operatively connected to the spindle;

a plurality of printheads;

a curing lamp; and

,

a controller operatively connected to the plurality of printheads, the first motor, the second motor, the curing lamp, the controller configured to operate the first motor, the second motor, the plurality of printheads, and the curing lamp,

wherein the plurality of printheads are configured to eject a first marking material onto the object and the second motor rotates the object in the first and/or second rotational direction.

2. The system of claim 1 further comprising an optical sensor, fixedly secured to the plurality of printheads or the spindle, the optical sensor operatively arranged to register a location of a first protrusion on a surface of the object.

3. The system of claim 2 wherein the plurality of printheads are connected to a third motor, the third motor operatively arranged to displace the printheads in a first lateral direction and a second lateral direction, where the first and second lateral directions are substantially parallel to the rod.

4. The system of claim 3 wherein the third motor is operatively arranged to displace the plurality of printheads in the first and/or second lateral directions in step-wise movements that begin at the registered location of the first protrusion.

5. The system of claim 1 wherein the first motor is further configured to rotate the rod in a first rotational direction and a second rotational direction to displace the object rotating subsystem in a first lateral direction and a second lateral direction, respectively, wherein the first lateral direction and the second lateral direction are substantially parallel with the rod.

6. The system of claim 1 further comprising a bracket, fixedly secured to the spindle and operatively arranged to engage a moveable component of the object.

7. The system of claim 6 wherein the moveable component is a handle.

8. The system of claim 1 wherein the plurality of printheads are positioned at a first distance relative to the surface of the object in a third lateral direction, where the third lateral direction is substantially orthogonal to the surface of the object.

9. The system of claim 1 wherein the curing lamp is positioned at a first distance relative to the surface of the object in a third lateral direction, where the third lateral direction is substantially orthogonal to the surface of the object.

10. The system of claim 1 wherein the curing lamp further comprises a plurality of light-emitting diodes.

11. The system of claim 10 wherein the plurality of light emitting diodes are configured to emit ultra-violet light.

12. The system of claim 1 further comprising a feedback sensor, fixedly secured to the spindle and arranged to register a first light intensity from the curing lamp at a start of the printing process.

13. The system of claim 12 wherein the feedback sensor is arranged to register a second light intensity from the curing lamp at a completion of the printing process.

14. The system of claim 1 wherein the object is a conical object.

15. The system of claim 1 wherein the object is a bucket.

16. A method of printing an image onto an object comprising:

creating a negative pressure with a vacuum source operatively connected to a spindle;

securing the object to a carrier, operatively arranged to rotate in a first rotational direction and a second rotational direction;

rotating the object with a first motor in the first rotational direction a first rotational distance;

sensing with at least one optical sensor a location of a first protrusion on an external surface of the object while the object is rotating;

stopping the rotation of the object in the first rotational direction;

rotating the object with the first motor in the second direction a second rotational distance, the second rotational distance is based on the location of the first protrusion;

displacing a printhead carrier with a second motor to a first position determined by the location of the first protrusion; and

printing an image onto the external surface of the object with a plurality of printheads arranged on the printhead carrier.

17. The method of printing an image onto an object of claim 16 further comprising:

splitting an image into a series of partitioned images; and

displacing the printhead carrier in a series of step-wise movements where each step-wise motion prints each of the partitioned images respectively, until the entire image is printed on the external surface of the object.
