Tool for forming a three dimensional container or construct
A tool having a blank positioning system and method for forming a container. The tool has a first tool assembly and a second tool assembly that cooperate to shape the container from a blank. The blank positioning system positions the blank between the first tool assembly and the second tool assembly prior to forming the blank into the container.
1. A method of forming a container from a blank, the method comprising:
obtaining a tool comprising a first tool assembly, a second tool assembly, and a blank positioning system, wherein the blank positioning system comprises a blank infeed table adjacent the at least one of the first tool assembly and the second tool assembly, wherein the blank infeed table has an upper face and a blank guiding surface comprising a contoured upper portion adjacent the upper face, and the blank positioning system further comprises a pair of blank guides, each blank guide of the pair of blank guides extending above the upper face of the blank infeed table, each blank guide of the pair of blank guides is spaced from the blank infeed table in a downstream direction, each blank guide of the pair of blank guides is oblique with respect to the downstream direction;
obtaining a blank to be formed into the container;
positioning at least one of the first tool assembly and the second tool assembly in an open position of the tool;
conveying the blank to the blank positioning system to position the blank between the first tool assembly and the second tool assembly, the conveying the blank comprises moving the blank in the downstream direction from an upstream end of the tool along the upper face of the blank infeed table and then engaging the blank with the blank guiding surface of the blank infeed table, and the conveying the blank further comprises engaging the blank with at least one of the blank guides of the pair of blank guides; and
positioning at least one of the first tool assembly and the second tool assembly in a closed position of the tool and pressing the blank between the tool assemblies to form the blank into the container.
2. The method of claim 1 wherein the blank infeed table comprises a lower face, the blank guiding surface comprises a lower portion adjacent the lower face, the upper portion of the blank guiding surface extends downwardly from the upper face to the lower portion.
3. The method of claim 1 wherein each blank guide of the pair of blank guides comprises a generally rectangular plate that is attached to the at least one of the first tool assembly and the second tool assembly.
4. The method of claim 1 wherein each blank guide of the pair of blank guides is a first blank guide and the blank positioning system comprises a pair of middle blank guides positioned in the downstream direction from the pair of first blank guides and the blank infeed table, wherein each middle blank guide of the pair of middle blank guides is positioned at an angle with respective to each first blank guide of the pair of first blank guides.
5. The method of claim 4 wherein each middle blank guide of the pair of middle blank guides comprises a generally rectangular plate that is attached to the at least one of the first tool assembly and the second tool assembly.
6. The method of claim 1 wherein the tool further comprises a pair of exit guides positioned in the downstream direction from the blank positioning system, the method further comprises discharging the container formed from the blank from the tool, and guiding the container with the pair of exit guides at a downstream end of the tool.
7. The method of claim 6 wherein each exit guide of the pair of exit guides comprises a generally rectangular plate that is attached to the at least one of the first tool assembly and the second tool assembly.
8. The method of claim 6 wherein the tool further comprises an exit plate positioned between the exit guides of the pair of exit guides, the discharging the container further comprises supporting the container on the exit plate.
9. The method of claim 1 wherein the first tool assembly comprises a nose having an external surface shaped to generally correspond to at least a portion of the container and the second tool assembly comprises a cavity block having a recess shaped to correspond with at least a portion of the container, the nose and the cavity block cooperating to form the container from the blank when the nose is at least partially received in the cavity block.
10. The method of claim 1 wherein the first tool assembly comprises a nose having an external surface shaped to generally correspond to at least a portion of the container and the second tool assembly comprises a cavity block having a recess, the pressing the blank between the tool assemblies to form the blank into the container comprises pressing the blank between the nose and the cavity block to form the blank into the container.
11. The method of claim 1 wherein at least one of the first tool assembly and the second tool assembly is moveable between the open position of the tool wherein the blank is received between the first and second tool assembly and the closed position of the tool wherein the blank is formed into the container.
12. The method of claim 11 wherein the blank positioning system is adjacent at least one of the first tool assembly and the second tool assembly.
13. The method of claim 12 wherein the blank positioning system has features for positioning the blank in an aligned position wherein the blank is axially aligned with the first tool assembly and the second tool assembly in the open position of the tool.
14. The method claim of claim 1 , wherein each blank guide of the pair of blank guides extends along respective opposite side surfaces of the blank infeed table.
15. The method of claim 14 , wherein each blank guide of the pair of blank guides further extends from a downstream end surface of the blank infeed table in the downstream direction.
16. A method of forming a container from a blank, the method comprising:
obtaining a tool comprising a first tool assembly, a second tool assembly, and a blank positioning system, wherein the blank positioning system comprises a blank infeed table adjacent the at least one of the first tool assembly and the second tool assembly, wherein the blank infeed table has an upper face, a blank guiding surface comprising a contoured upper portion adjacent the upper face, and opposing side surfaces, and the blank positioning system further comprises a air of blank guides, each blank guide of the air of blank guides extending above the upper face of the blank infeed table, and each blank guide of the pair of blank guides extends along the respective side surfaces of the blank infeed table;
obtaining a blank to be formed into the container;
positioning at least one of the first tool assembly and the second tool assembly in an open position of the tool;
conveying the blank to the blank positioning system to position the blank between the first tool assembly and the second tool assembly, the conveying the blank comprises moving the blank in a downstream direction from an upstream end of the tool along the upper face of the blank infeed table and then engaging the blank with the blank guiding surface of the blank infeed table; and
positioning at least one of the first tool assembly and the second tool assembly in a closed position of the tool and pressing the blank between the tool assemblies to form the blank into the container.
17. The method of claim 16 , wherein each blank guide of the pair of blank guides further extends from the blank guiding surface of the blank infeed table in the downstream direction.
