Abstract

Embodiments of the invention add a cutting tool and a creasing wheel to a flatbed printer. This reduces workflow steps, allows cutting and creasing without having to re-register image/media, and reduces required floor space for small shops.

First claim

The invention claimed is:

1. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side; and
a print head affixed to said carriage comprising:
at least one ink jet;
a cutting device; and
a creasing device;

wherein said gantry and carriage effect coordinated movement of said print head with respect to a medium registered to said print bed and sequential operation of said at least one ink jet, said cutting device, and said creasing device to print an image on said medium, cut a pattern in said medium, and crease said medium while said medium is stationary on said print bed; and
wherein cutting speed and/or pressure and/or creasing speed and/or pressure are selectably variable.

2. The flatbed printer of claim 1 , further comprising:
one or more pins positioned on the print bed to effect registration of the medium to the head assembly for accurate printing, cutting, and creasing.

3. The flatbed printer of claim 1 , further comprising:
an alignment bar positioned at one or more edges of the print bed to effect registration of the medium to the head assembly for accurate printing, cutting, and creasing.

4. The flatbed printer of claim 1 , further comprising:
an imaging system configured to capture a location of the medium on the print bed and adjust travel of the gantry and carriage to effect registration of the medium to the head assembly for accurate printing, cutting, and creasing.

5. The flatbed printer of claim 1 , further comprising:
a vacuum assisted holding mechanism configured to secure the medium to the print bed during printing, cutting, and creasing.

6. The flatbed printer of claim 1 , the cutting device further comprising:
any of a laser, a diode laser, a CO2 laser, a CNC style router spindle, and a bladed device.

7. The flatbed printer of claim 6 , further comprising:
an exhaust that draws fumes, which result when the laser cuts the medium, away from the printer.

8. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side;
a print head affixed to said carriage comprising:
at least one ink jet;
a cutting device; and
a creasing device;

wherein said gantry and carriage effect coordinated movement of said print head with respect to a medium registered to said print bed and sequential operation of said at least one ink jet, said cutting device, and said creasing device to print an image on said medium, cut a pattern in said medium, and crease said medium while said medium is stationary on said print bed; and
a user dashboard with which cutting parameters and creasing parameters are set when setting the print parameters.

9. The flatbed printer of claim 1 , wherein upon completion of printing the medium, the printer cuts and creases the medium based on instructions embedded in printing information for a current image.

10. The flatbed printer of claim 1 , wherein said medium comprises any of:
paper, cardstock, corrugated materials, cardboard, PSA/films, textiles, acrylic, expanded PVC, wood, polystyrene, aluminum composite (dibond), or heat sensitive media (FOME-COR).

11. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side; and
a print head affixed to said carriage comprising:
at least one ink jet;
a cutting device; and
a creasing device;

wherein said gantry and carriage effect coordinated movement of said print head with respect to a medium registered to said print bed and sequential operation of said at least one ink jet, said cutting device, and said creasing device to print an image on said medium, cut a pattern in said medium, and crease said medium while said medium is stationary on said print bed; and
wherein coordinated axis motion of the carriage and gantry is effected for cutting of curves and circles.

12. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side; and
a print head affixed to said carriage comprising:
at least one ink jet;
a cutting device; and
a creasing device;

wherein said gantry and carriage effect coordinated movement of said print head with respect to a medium registered to said print bed and sequential operation of said at least one ink jet, said cutting device, and said creasing device to print an image on said medium, cut a pattern in said medium, and crease said medium while said medium is stationary on said print bed; and
wherein cutting device power output is adjustable.

13. The flatbed printer of claim 12 , wherein a cutting device power adjustment signal is provided to the printer with imaging, cutting, and creasing instructions.

14. The flatbed printer of claim 1 , said cutting device further comprising:
a flame detector for verification that a flame is not present after the cutting device is stopped.

15. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side; and
a print head affixed to said carriage comprising:
at least one ink jet;
a cutting device; and
a creasing device;

wherein said gantry and carriage effect coordinated movement of said print head with respect to a medium registered to said print bed and sequential operation of said at least one ink jet, said cutting device, and said creasing device to print an image on said medium, cut a pattern in said medium, and crease said medium while said medium is stationary on said print bed; and
wherein said printer is configurable to temporarily receive any of a plurality of creasing devices.

16. The flatbed printer of claim 15 , said creasing device configured for creating any of:
a thin crease line, a thick crease line, and a double crease line.

17. The flatbed printer of claim 1 , wherein said creasing device is any of pneumatically and electrically operated.

18. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side; and
a print head affixed to said carriage comprising:
at least one ink jet;
a cutting device; and
a creasing device;

wherein said gantry and carriage effect coordinated movement of said print head with respect to a medium registered to said print bed and sequential operation of said at least one ink jet, said cutting device, and said creasing device to print an image on said medium, cut a pattern in said medium, and crease said medium while said medium is stationary on said print bed; and
wherein said creasing device is rotatably operable to maintain alignment with a direction of travel of said gantry and said carriage.

19. A flatbed printer, comprising:
a print bed;
a gantry configured to traverse the print bed from front-to-back;
a carriage affixed to the gantry and configured to traverse the print bed from side-to-side; and
a print head affixed to said carriage comprising:
