Abstract

A method and a system for erecting boxes from box templates of different sizes, said method comprising the steps of:adjusting a size of a frame according to a size of a box template which should be erected;wrapping the box template to be erected around the frame; andseparating the frame from the box template.

First claim

The invention claimed is:

1. A method for erecting boxes from box templates of different sizes, said method comprising the steps of:
adjusting a size of a frame according to a size of a box template which should be erected adjusting the size of the frame comprising adjusting distances between four adjustable corner posts of the frame, each of the four adjustable corner posts being separate and distinct from one another, and distances between each of the four adjustable corner posts and the other corner posts being selectively adjustable;
wrapping the box template to be erected around the frame; and
separating the frame from the box template.

2. The method according to claim 1 , further comprising a step of sealing a manufacturer's joint of the box template before separating the frame from the box template.

3. The method according to claim 1 , further comprising folding a bottom of the box template before separating the frame from the box template.

4. The method according to claim 3 , further comprising sealing the bottom before separating the frame from the box template.

5. The method according to claim 1 , wherein the step of wrapping comprises:
attaching a box template to be erected to the frame; and
controlling the position of the frame by a control system connected to the frame such that the box template is wrapped around the frame.

6. The method according to claim 5 , wherein the step of attaching the box template to the frame comprises attaching a first end of the box template to one of four corner posts provided in the frame.

7. The method according to claim 5 , wherein controlling of the position of the frame comprises rotating the frame for wrapping the box template around the frame.

8. The method according to claim 7 , wherein controlling of the position of the frame further comprises moving the frame laterally.

9. The method according to claim 1 , further comprising a step of sealing a manufacturer's joint of the box template before separating the frame from the box template, said step of sealing the manufacturer's joint comprising providing glue to a part of the box template which will be a part of the manufacturer's joint before the box template has been completely wrapped around the frame.

10. The method according to claim 9 , wherein the step of sealing the manufacturer's joint further comprises controlling the position of the frame by a control system connected to the frame or controlling the position of a sealing device such that the box template and the sealing device pass each other before the box template is completely wrapped around the frame, said sealing device being connected to and controlled by the control system to eject glue to the box template for sealing the manufacturer's joint when the box template and the sealing device pass each other.

11. The method according to claim 1 , wherein the step of adjusting the size of the frame comprises controlling the size of the frame by a control system connected to the frame, wherein said adjusting comprises controlling, by the control system, distances between at least two of the four corner posts in the frame.

12. The method according to claim 1 , wherein the step of wrapping the box template around the frame comprises positioning a distant end of the frame in line with bottom flap creases of the box template such that a bottom can be folded while keeping the frame inside the wrapped box template.

13. A method for erecting a box from a box template, said method comprising:
adjusting a size of a frame according to a size of the box template that is to be erected into a box, the frame comprising a plurality of adjustable corner posts defining a size of the frame, each of the plurality of adjustable corner posts having a longitudinal axis, the longitudinal axes of the plurality of adjustable corner posts being generally parallel to one another;
attaching a first end of the box template the frame; and
rotating the frame about a rotational axis to wrap the box template around the frame, the rotational axis being generally parallel to the longitudinal axes of the plurality of adjustable corner posts.

14. The method according to claim 13 , wherein adjusting the size of the frame comprises adjusting distances between at least two of the plurality of adjustable corner posts of the frame.

15. The method according to claim 14 , wherein attaching the first end of the box template to the frame comprises attaching the first end of the box template to one of the plurality of adjustable corner posts of the frame.

16. The method according to claim 13 , further comprising folding two first bottom flaps and two second bottom flaps of the box template, the first and second bottom flaps being configured to form a bottom of the box when erected and the two first bottom flaps opposing each other and the two second bottom flaps opposing each other when the box is erected.

17. The method according to claim 16 , wherein folding the two first bottom flaps and the two second bottom flaps comprises folding the two first bottom flaps a first amount and folding the two second bottom flaps a second amount that is different than the first amount.

18. The method according to claim 13 , further comprising sealing a manufacturer's joint and a bottom of the box and then separating the erected box from the frame.

19. The method according to claim 18 , wherein sealing a manufacturer's joint and a bottom of the box comprises providing glue to the first end or a second end of the box template and to the first or the second bottom flaps before the box template has been completely wrapped around the frame and compressing the manufacturer's joint and compressing the first bottom flaps towards the second bottom flaps to seal the bottom.

20. A box erecting system for erecting a box from a box template, the box erecting system comprising:
a frame comprising at least four adjustable corner posts, distances between the adjustable corner posts being adjustable to vary distances therebetween and dimensions of the frame to correspond to dimensions of a box being formed, the at least four adjustable corner posts having generally parallel longitudinal axes, the frame being rotatable about a rotation axis to enable wrapping of a box template therearound to form a box, the rotation axis being generally parallel to the longitudinal axes of the at least four adjustable corner posts;
an attaching device connected to at least one of the at least four adjustable corner posts of the frame and configured for attaching the frame to a box template that is to be erected into a box; and
a control system configured to control:
the adjustment of the at least four adjustable corner posts;
the rotation of the frame; and
the activation and/or deactivation of the attaching device.
