Abstract

An automated system for assembling a framed article including a plurality of canvases and a plurality of assembled frames to be combined with the plurality of canvases to form the framed articles. Each assembled frame is formed of a rear panel and a frame member that are detachably attached to one another with one canvas being stretched across a front face of the frame member. The automated system includes an assembly station including a movable presser head that is configured to detach and lift the rear panel from the frame member and a plurality of movable side guide fingers that are configured to fold side edges of the canvas over sides of the frame member to permit the presser head to press the rear panel down over the folded side edges of the canvas into engagement with the frame member with the canvas being captured between the frame member and the rear panel.

First claim

What is claimed is:

1. An automated system for assembling a framed article comprising:
a plurality of canvases;
a plurality of assembled frames to be combined with the plurality of canvases to form the framed articles, each assembled frame being formed of one rear panel and one frame member that are detachably attached to one another with one canvas being stretched across a front face of one respective frame member;
a transfer device for transferring one canvas of the plurality of canvases from a first location to a second location; and
an assembly station, at the second location, that receives the one canvas and includes a movable presser head that is configured to detach and lift one rear panel from one respective frame member that defines, in combination with the one rear panel, one assembled frame, the assembly station being configured to press the one rear panel down over the folded side edges of the canvas into engagement with the one frame member with the canvas being captured between the one frame member and the one rear panel.

2. The automated system of claim 1 , wherein the assembly station includes a bed having a recessed pocket formed therein, the recessed pocket being configured to receive the canvas and the one assembled frame, the bed further including a four linear slots formed therein and being located in and being open in corners of the recessed pocket.

3. The automated system of claim 2 , further including a corner tucking mechanism that is configured to tuck in and invert pleated corners of the canvas, the corner tucking mechanism comprising four corner tucking devices that are located in the four linear slots, each of the four corner tucking devices being operable to tuck in and invert one of the pleated corners of the canvas.

4. The automated system of claim 3 , wherein each of the four corner tucking devices comprises a first tucking element and a second tucking element, the first tucking element being located proximate the open end of the linear slot, while the second tucking element being located proximate a closed end of the linear slot.

5. The automated system of claim 4 , wherein the second tucking element comprises a pair of spaced fingers with an open space therebetween, the second tucking element pivoting between a first position in which hooked shaped distal ends of the pair of spaced fingers are located closer to the closed end of the linear slot and a second position in which the hooked shaped distal ends are located closer to the open end of the linear slot.

6. The automated system of claim 5 , wherein in the first position, the hooked shaped distal ends are facing upward and in the second position, the hooked shaped distal ends are facing downward.

7. The automated system of claim 5 , wherein the first tucking element is disposed within the open space between the pair of spaced fingers and moves between a retracted position and a pivoted extended position in which the first tucking element drives and inverts the pleated corner of the canvas.

8. The automated system of claim 1 , further including a plurality of movable side guide fingers that are configured to fold side edges of the canvas over sides of the one frame member to permit the presser head and wherein the plurality of canvases are stored in a stack at a canvas feed station, at the first location, spaced from the assembly station.

9. The automated system of claim 8 , wherein the canvas feed station includes the transfer device that is configured to retrieve the one canvas from the stacked plurality of canvases and deliver the one canvas to a target location of the assembly station.

10. The automated system of claim 9 , wherein the transfer device has a carriage that rides along a guide track between the canvas feed station and the assembly station, the carriage having a plurality of grippers for selectively gripping and transporting the one canvas.

11. The automated system of claim 10 , wherein each gripper includes a suction cup that has one or more suction ports that are operatively connected to a source of negative pressure for generating suction at the suction cup to allow the suctions cups to hold the one canvas by suction when the negative pressure is applied to the suction cups.

12. The automated system of claim 1 , further including a reader station spaced from and facing the assembly station, the reader station including a reader that reads a first unique identifier that is located along the canvas.

13. The automated system of claim 12 , wherein the first unique identifier comprises a barcode printed along one edge of the canvas.

14. The automated system of claim 12 , further including an ID application station at which a second unique identifier is placed on the assembled framed article.

15. The automated system of claim 1 , wherein the assembly station includes a bed having a recessed pocket formed therein, the recessed pocket being configured to receive the canvas and the one assembled frame.

16. The automated system of claim 15 , wherein the plurality of movable side guide fingers are disposed about the recessed pocket and in pivoted positions, distal ends of the movable side guide fingers are located over the recessed pocket.

17. The automated system of claim 1 , wherein the presser head includes a main body and is configured to move in an up and down direction, the main body having a plurality of gripper pins each of which moves between a retracted position and an extended position, wherein in the extended positions, the gripper pins are received in spaces formed in the rear panel, thereby allowing the presser head to lift up the rear panel.

18. The automated system of claim 17 , wherein the plurality of gripper pins comprises two gripper pins located at opposite ends of the main body.

19. The automated system of claim 1 , wherein each assembled frame includes a frame member and a rear panel that snap-fittingly attaches to the frame member in a detachable manner.

20. The automated system of claim 1 , wherein opposing edges of the canvas have notches and the assembly station includes locating pins that moves between retracted positions and extended positions in which the locating pins are received in the notches of the canvas.

21. An automated system for assembling a framed article comprising:
a plurality of canvases;
a plurality of assembled frames to be combined with the plurality of canvases to form the framed articles, each assembled frame having one stretched canvas thereacross;
a transfer device for transferring one canvas of the plurality of canvases from a first location to a second location; and
an assembly station, at the second location, that receives the one canvas and includes a bed having a recessed pocket formed therein, the recessed pocket being configured to receive the canvas and the one assembled frame during an assembly step in which the one canvas is attached to the one assembled frame.
