Abstract

A method of operating a crafting apparatus. The method includes moving a workpiece along a first feed path for printing on the workpiece with a printer and moving the workpiece along a second feed path for cutting the workpiece with a cutter. The first feed path bypasses a workpiece mover of the cutter.

Claims

1. A method of operating a crafting apparatus, the method comprising:

moving a feed path bypass assembly disposed along at least one passageway between a cutter and a printer to a first position, the feed path bypass assembly directing movement of a received workpiece along a first feed path that bypasses a first pair of rollers disposed adjacent the cutter;

receiving the workpiece between a second pair of rollers disposed adjacent the printer for selectively controlling movement of the workpiece with respect to the printer during printing operations;

printing on the workpiece using the printer;

moving the feed path bypass assembly to a second position, the feed path bypass assembly directing movement of the workpiece along a second feed path between the first pair of rollers that receive and selectively control movement of the workpiece with respect to the cutter during cutting operations;

cutting the workpiece using the cutter; and

moving a first toggle member to a first position allowing a second toggle member disposed along the at least one passageway downstream of the cutter and upstream of the printer to pivot to a corresponding first position, allowing movement of the workpiece along the first feed path bypassing the first pair of rollers.

2. The method of claim 1, further comprising moving the workpiece along the first feed path in a first direction while the feed path bypass assembly is in its first position and moving the workpiece along the second feed path in a second direction substantially opposite to the first direction while the feed path bypass assembly is in its second position.

3. The method of claim 1, further comprising moving the second pair of rollers to an engaged position for engaging and moving the workpiece therebetween when the feed path bypass assembly is in its first position.

4. The method of claim 3, wherein movement of the feed path bypass assembly to its first position causes movement of the second pair of rollers to its engaged position.

5. The method of claim 1, further comprising moving the second pair of rollers to a disengaged position allowing free movement of the workpiece therebetween when the feed path bypass assembly is in its second position.

6. The method of claim 5, wherein movement of the feed path bypass assembly to its second position causes movement of the second pair of rollers to its disengaged position.

7. The method of claim 1, further comprising moving a carrier arm disposed along the at least one passageway and rotatably supporting an upper roller of the second pair of rollers to a first position upon moving the second toggle member to its first position, the carrier arm selectively engaging the upper roller of the second pair of rollers against a lower roller of the second pair of rollers while in its first position.

8. The method of claim 7, further comprising moving the first toggle member to a second position allowing the second toggle member to pivot to a corresponding second position, allowing movement of the workpiece along the second feed path between the first pair of rollers.

9. The method of claim 8, further comprising moving the carrier arm to its second position disengaging contact between the second pair of rollers upon moving the second toggle member to its second position.

10. The method of claim 1, further comprising inducing a curvature in the workpiece about a direction of movement of the workpiece as the workpiece moves downstream of the printer.

11. The method of claim 10, further comprising moving the workpiece past an exit ramp disposed downstream of the printer, a portion of the exit ramp defining an arcuate profile transverse to the feed path of the workpiece to induce the curvature of the workpiece.

12. The method of claim 11, further comprising maintaining the workpiece substantially flat upstream of the arcuate profiled portion of the exit ramp.

13. The method of claim 12, further comprising moving the workpiece past edge holders that engage lateral edge portions of the workpiece to maintain the workpiece substantially flat.

14. The method of claim 1, further comprising determining a workpiece alignment, the workpiece alignment comprising at least one of an angular skew and a lateral offset of the workpiece with respect to the feed path of the workpiece.

15. The method of claim 14, further comprising moving first and second sensors along respective first and second orthogonal directions for detecting at least one of an edge of the workpiece and a fiducial on at least one of a mat supporting the workpiece and the workpiece and determining the workpiece alignment based on a coordinate signal from each sensor.

16. The method of claim 15, wherein each sensor detects at least one of a top edge, a left edge and a right edge of the workpiece.

17. The method of claim 14, further comprising cutting the workpiece based on the determined workpiece alignment.

18. The method of claim 14, further comprising printing an image on the workpiece based on the determined workpiece alignment.
