Abstract

A parallel belt system for a laser cutter module and a method or non-transitory computer readable medium for transporting a cut sheet of media through a laser cutter in a printer is disclosed. For example, the parallel belt system includes a rotating shaft, a plurality of pairs of o-rings movably coupled to the rotating shaft, a plurality of belts for receiving a cut sheet of media, a guide for each one of the plurality of belts for holding a respective one of the plurality of belts rigid, a laser cutter for cutting a portion of the cut sheet of media and a collection module coupled below the plurality of belts for collecting the portion of the cut sheet of media that is cut by the laser cutter.

First claim

What is claimed is:

1. A parallel belt system for a laser cutter module, comprising:
a rotating shaft;
a plurality of belts coupled to the rotating shaft for receiving a cut sheet of media, wherein each one of the plurality of belts rotates to move the cut sheet of media through the laser cutter module, wherein the plurality of belts is positioned parallel to one another;
a guide for each one of the plurality of belts for holding a respective one of the plurality of belts rigid;
a laser cutter for cutting a portion of the cut sheet of media;
a collection module coupled below the plurality of belts for collecting the portion of the cut sheet of media that is cut by the laser cutter; and
a vacuum plenum coupled to one of the plurality of belts, wherein the one of the plurality of belts comprises a plurality of openings to allow the vacuum plenum to hold the cut sheet of media against the one of the plurality of belts.

2. The parallel belt system of claim 1 , wherein the cut sheet of media is fed between the plurality of belts and the guide.

3. The parallel belt system of claim 1 , wherein the plurality of belts comprises a top belt and a bottom belt for each gutter of the cut sheet of media and the cut sheet of media is fed between the top belt and the bottom belt.

4. The parallel belt system of claim 1 , wherein each one of the plurality of belts is movable in an in-board direction or an out-board direction based on a gutter position of the cut sheet of media.

5. The parallel belt system of claim 1 , further comprising:
one or more pairs of o-rings, wherein each one of the plurality of belts is coupled to a respective pair of the one or more pairs of o-rings, wherein the one or more pairs of o-rings are moved automatically via a mechanical means or an electrical means.

6. The parallel belt system of claim 1 , wherein a number of the plurality of belts is a function of a number of columns used in the cut sheet of media.

7. The parallel belt system of claim 1 , wherein the collection module comprises a stationary module.

8. The parallel belt system of claim 1 , wherein the collection module comprises a moving belt.

9. The parallel belt system of claim 1 , wherein the laser cutter module is in a laser printer.

10. A method for transporting a cut sheet of media through a laser cutter in a printer, comprising:
determining a location of each gutter of the cut sheet of media;
aligning two or more belts to the location of each gutter of the cut sheet of media, wherein each one of the two or more belts is coupled to a rotating shaft and held rigid by a guide;
receiving the cut sheet of media by the two or more belts;
cutting a portion of the cut sheet of media;
collecting the portion of the cut sheet of media below and between the two or more belts; and
turning on a vacuum plenum to create a vacuum between the cut sheet of media and one or more openings on each one of the two or more belts.

11. The method of claim 10 , wherein the two or more belts comprise a top belt and a bottom belt associated with the each gutter, wherein the receiving comprises receiving the cut sheet of media between the top belt and the bottom belt associated with the each gutter.

12. The method of claim 10 , wherein the aligning comprises moving one or more of the two or more belts in an in-board direction or an out-board direction.

13. The method of claim 10 , wherein the aligning comprises moving a pair of o-rings that are coupled to each one of the two or more belts automatically via a mechanical means or an electrical means.

14. The method of claim 10 , wherein the determining is performed by a processor of the printer.

15. The method of claim 10 , wherein the collecting is performed via a moving belt or a stationary module.

16. The method of claim 10 , wherein the determining, the aligning, the receiving, the cutting and the collecting are repeated continuously for consecutively fed cut sheets of media.

17. A non-transitory computer-readable medium storing a plurality of instructions which, when executed by a processor, cause the processor to perform operations for transporting a cut sheet of media through a laser cutter in a printer, the operations comprising:
determining a location of each gutter of the cut sheet of media;
aligning two or more belts to the location of each gutter of the cut sheet of media, wherein each one of the two or more belts is coupled to a rotating shaft and held rigid by a guide;
receiving the cut sheet of media by the two or more belts;
cutting a portion of the cut sheet of media;
collecting the portion of the cut sheet of media below and between the two or more belts; and
turning on a vacuum plenum to create a vacuum between the cut sheet of media and one or more openings on each one of the two or more belts.
