Abstract

A machine for transitioning a box cutout from a flat configuration to a collapsed box configuration includes a first drive wheel configured to drive a box cutout towards a plunging area; a plunger configured to apply force to a central portion of a bottom panel of the box cutout so as to fold the box about a lateral bisecting axis and propel at least a portion of the box cutout downward; and opposed second and third drive wheels configured to grab a box cutout propelled downward by the plunger and further draw the box cutout downward into a collapsed box configuration within a collection area. A box cutout transitioned to a collapsed box configuration in this manner may include a bottom panel having plurality of unbroken minor score lines and broken major score lines.

Claims

1. A method of transitioning a box cutout from a flat unfolded configuration to a collapsed box configuration, the method comprising:

(a) driving, via one or more drive wheels, a box cutout toward a plunging area;

(b) detecting, via a first detector, the presence of the box cutout;

(c) applying, via one or more glue applicators, glue to the box cutout;

(d) facilitating halting, via a backstop, the movement of the box cutout when it is located within the plunging area;

(e) detecting, via a second detector, the presence of the box cutout;

(f) holding the box cutout in position with one or more clamps;

(g) in response to the step of detecting, via the second detector, the presence of the box cutout, folding, via one or more rotational fingers, the box cutout;

(h) after the step of folding the box cutout, applying downward force, via a plunger, to a central portion of the box cutout disposed below the plunger so as to effect at least partial collapsing of the box cutout and downward movement of the box cutout;

(i) guiding, via one or more guide wheels located below the plunging area, the descent of the box cutout as the box cutout is being plunged by the plunger;

(j) engaging, via opposed grab wheels located below the one or more guide wheels, the box cutout that has been plunged downward by the plunger, the opposed grab wheels pressing opposite sides of the box cutout together and propelling the box cutout in a downward direction; and

(k) effecting placement, using a collector, of the box cutout in a collection pen.

2. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the backstop and one of the drive wheels are each positioned relative to the plunger based on dimensions of a particular box cutout.

3. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein a width of a plunging head of the plunger corresponds to the length of a portion of a score line of a particular box cutout.

4. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the method further includes a step of deflecting, using a deflector adjacent the plunger, the box cutout downward.

5. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the method further includes a step of detecting, via a third detector, plunging of the plunger, and wherein the collector is configured to, based on a count of plunges detected by the third detector, elevate the particular collected box cutout when effecting placement of the collected box cutout in the collection pen.

6. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the one or more drive wheels comprise two drive wheels.

7. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the one or more guide wheels comprise two opposed sets of two guide wheels.

8. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the method further includes a step of dropping the cutout down from a cutout receiving area in which the cutout was received, the cutout receiving area being configured to receive a plurality of box cutouts for processing.

9. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 1, wherein the method further includes a step of removing a plunging head of the plunger and replacing it with a different plunging head.

10. A box cutout transitioned to a collapsed box configuration in accordance with the method of claim 1, wherein the box cutout in the collapsed box configuration comprises a score line bisecting the bottom panel, a plurality of minor bottom score lines configured for folding of the box cutout, and a plurality of major bottom score lines configured for folding of the box cutout, wherein the bottom panel of the box cutout is collapsed downward about the score line bisecting the bottom panel and the plurality of major bottom score lines, but each of the minor bottom score lines is unbroken.

11. A method of transitioning a box cutout from a flat unfolded configuration to a collapsed box configuration, the method comprising:

(a) facilitating halting, via a backstop, movement of a box cutout when it is located within a plunging area;

(b) detecting, via a detector, the presence of the box cutout;

(c) holding the box cutout in position with one or more clamps;

(d) folding, via one or more rotational fingers, the box cutout;

(e) applying downward force, via a plunger, to a central portion of the box cutout disposed below the plunger so as to effect at least partial collapsing of the box cutout and downward movement of the box cutout;

(f) guiding, via one or more guide wheels located below the plunging area, the descent of the box cutout as the box cutout is being plunged by the plunger; and

(g) engaging, via opposed grab wheels located below the one or more guide wheels, the box cutout that has been plunged downward by the plunger, the opposed grab wheels pressing opposite sides of the box cutout together and propelling the box cutout in a downward direction.

12. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein the backstop is positioned relative to the plunger based on dimensions of a particular box cutout.

13. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein a width of a plunging head of the plunger corresponds to the length of a portion of a score line of a particular box cutout.

14. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein the method further includes a step of deflecting, using a deflector adjacent the plunger, the box cutout downward as the box cutout enters the plunging area.

15. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein the method further includes a step of detecting, via another detector, plunging of the plunger and counting the number of times the plunger has been detected for effecting a placement of a collected box cutout in a collection pen that is different from other collected box cutouts in the collection pen.

16. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein the one or more guide wheels comprise two opposed sets of two guide wheels.

17. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein the method further includes a step of removing a plunging head of the plunger and replacing it with a plunging head that has a different size.

18. The method of transitioning a box cutout from a flat configuration to a collapsed box configuration of claim 11, wherein the method further includes a step of removing a plunging head of the plunger and replacing it with a plunging head that has a different shape.

19. A method of transitioning a box cutout from a flat unfolded configuration to a collapsed box configuration, the method comprising:
