Abstract

A printing apparatus including a conveyor capable of moving an object in a process direction, a drop ejection device, a sensor array that substantially spans the conveyor in a cross-process direction that is perpendicular to the process direction, the sensor array being configured to detect a position of the object in the process direction and cross-process direction, and a controller configured to receive position data about the object from the sensor array and to cause the drop ejection device to deposit fluid droplets on the object based on the position of the object on the conveyor.

Claims

AMENDED CLAIMS received by the International Bureau on 13 March 2010 (12.03.10)
1. A printing apparatus comprising, a conveyor capable of moving a plurality of objects in a process direction, the plurality of objects randomly placed on the conveyor; a drop ejection device; a sensor array that substantially spans the conveyor in a cross-process direction that is perpendicular to the process direction, the sensor array being configured to detect a position of an object in the process direction and the cross-process direction; and a controller configured to receive position data about the object from the sensor array and to cause the drop ejection device to deposit fluid droplets on the object based on the position of the object on the conveyor.
2. The apparatus of claim 1 , wherein the sensor array is configured to detect more than one object at a time.
3. The apparatus of claim 1 , wherein the sensor array is configured to detect a leading edge.
4. The apparatus of claim 2, wherein the controller is configured to cause the drop ejection device to deposit fluid droplets on more than one object at a time,
5. The apparatus of claim 1 , wherein the controller is configured to combine the position data with image data to create print data that is sent to the drop ejection device.
6. The apparatus of claim 5, wherein the position data and image data comprise a plurality of scan lines comprising binary data including Is and Os, 1 for active and 0 for inactive, and the controller configured to combine the position data and image data using an AND function.
7. The apparatus of claim 5, further comprising a memory that receives the print data from the controller and sends the print data to the drop ejection device.
8. The apparatus of claim 5, further comprising an image database for storing at least one image data that is sent to the controller,
9. The apparatus of claim 1 „ wherein the controller comprises software configured to determine a center of the object based on the position data and to add the print data to the memory based on the 'center of the object.
10. The apparatus of claim 1 , wherein the controller comprises software configured to determine an angle of the object and to adjust the image data to correspond to the angle of the object.
11. The apparatus of claim 1 , further comprising a delay mechanism that delays the drop ejection from depositing fluid droplets until the object has traveled from the sensor to the drop ejection device.
12. The apparatus of claim 11 , wherein the drop ejection device comprises a plurality of jetting arrays,
13. The apparatus .of claim 12, wherein each jetting array comprises a plurality of modules , each module configured to deposit a different color ink.
14. The apparatus of claim 13, wherein the delay mechanism delays the drop ejection device from depositing ink from each module until the object has reach that module.
15. The apparatus of claim 1 , wherein the sensor array is a charge coupled device camera.
16. The apparatus of claim I3 wherein the sensor array has a resolution that matches a resolution of the drop ejection device,
17. The apparatus of claim 1, wherein the resolution of the drop ejection device is 100 dpi.
15
18. The apparatus of claim 1 , wherein the sensor array is stationary relative to the conveyor.
19. The apparatus of claim I5 wherein the drop ejection device is stationary relative to the conveyor.
20. A method comprising: moving a plurality of objects on a conveyor in a process direction, the plurality of objects randomly placed on the conveyor; detecting a position of an object in the process direction and a cross-process direction, which is perpendicular to the process diiectiorij using a sensor array that substantially spans the conveyor in the cross-process direction; adding image data to a memory in a space corresponding to the position data; and causing a drop ejection device to deposit fluid droplets on the object based on the position of the object on the conveyor,
21. The method of claim 20, wherein the position of the object is detected by a charge coupled device camera.
22. The method of claim 213 further comprising matching a resolution of the camera to a resolution of the drop ejection device.
23. The method of claim 20, further comprising delaying the drop ejection device from depositing droplets until the object has reached the drop ejection device.
24. The method of claim 20, wherein the sensor array is stationary relative to the conveyor.
25. The method of claim 20, wherein the drop ejection device is stationary relative to the conveyor.
16
26. The method of claim 20, further comprising sending position data to a controller, combining the position data with image data to create print data, and sending the print data to the drop ejection device.
27. The method of claim 26, further comprising sending the print data to a memory before sending the print data to the drop ejection device.
28. A printing apparatus comprising: a conveyor divided into a plurality of lanes for moving objects relative to a drop ejection device; a plurality of sensors including at least one sensor for each lane, the sensors being configured to detect a leading edge of an object; a controller configured to receive signals from the plurality of sensors when objects are detected, the controller configured to determine the lane that corresponds to the signal and to send image data to that lane; and a memory for receiving image data from the controller, the memory being configured to enter the image data into the memory corresponding to the lane, and the memory being configured to send the image data to the drop ejection device to deposit fluid droplets on the object moving through the corresponding lane.
29. A fluid ejection method comprising: moving a plurality of objects on a conveyor having a plurality of lanes; detecting an object moving through one of the plurality of lanes using a sensor; after detecting the object, creating a virtual representation of the object moving on the conveyor; and depositing fluid droplets on the object in that lane.
