Abstract

Methods, devices, apparatus, and assemblies for converting fanfold material into packaging templates are disclosed. A converting system includes a converting machine that performs various conversion functions on the fanfold material. An infeed guide system directs the fanfold material from one or more stacks into the converting machine without folding, creasing, or otherwise compromising the fanfold material. The infeed guide system includes infeed guides with substantially S-shaped segments. The infeed guide system also includes a frame structure that substantially maintains the curvature of the substantially S-shaped segments within a desired range to prevent damage to or jamming of the fanfold material in the infeed guide system.

First claim

What is claimed is:

1. A feed system for feeding raw material into a converting machine, the feed system comprising:
a plurality of infeed guides, each of the plurality of infeed guides comprising a first end, a second end disposed adjacent said converting machine, and a S-shaped segment between the first and second ends, the S-shaped segment having a center portion, wherein raw material can be fed between the first and second ends through the S-shaped segment, wherein the plurality of infeed guides comprises two or more vertically spaced apart infeed guides that define one or more guide passages through which the raw material can be passed; and
a frame supporting the plurality of infeed guides, the frame comprising a pivoting frame that is adapted to selectively change the height of the center portion of each S-shaped segment of the plurality of infeed guides.

2. The feed system recited in claim 1 , wherein the height of the second end of each infeed guide can be changed to direct a different raw material into said converting machine.

3. The feed system recited in claim 2 , wherein the pivoting frame changes the height of the center portion of each S-shaped segment when the height of the second end of each infeed guide is changed.

4. The feed system recited in claim 1 , wherein the pivoting frame comprises at least one pivoting beam having a first end that is pivotally coupled to a main frame structure.

5. The feed system recited in claim 4 , wherein the at least one pivoting beam comprises a second end operatively associated with a cassette changer that is adapted to change the height of the second ends of the plurality of infeed guides, wherein the height of the second end of the at least one pivoting beam changes in correspondence with the changing heights of the second ends of the plurality of infeed guides.

6. The feed system recited in claim 5 , wherein the at least one pivoting beam is linked to the center portions of the S-shaped segments of the infeed guides, whereby changes in the height of the second end of the at least one pivoting beam causes a change in the height of the center portions of the S-shaped segments of the infeed guides.

7. The feed system recited in claim 1 , wherein the raw material comprises a fanfold material.

8. The feed system recited in claim 7 , wherein the fanfold material is fanfold corrugated board.

9. A converting system used to convert fanfold material into packaging templates for assembly into boxes or other packaging, the fanfold material being stacked and having score lines separating layers of the fanfold material, wherein the converting system comprises:
a converting machine configured to receive and perform one or more conversion functions on said fanfold material, the one or more conversion functions including creasing, bending, folding, perforating, cutting, scoring, or any combination thereof, to create said packaging template; and
an infeed guide system disposed adjacent to the converting machine, the infeed guide system comprising:
a plurality of infeed guides adapted to direct said fanfold material into the converting machine, each of the plurality of infeed guides having a first end, a second end disposed adjacent the converting machine, and a S-shaped segment between the first and second ends, wherein the second end of each infeed guide is adapted for vertical repositioning; and
a grate connected to the plurality of infeed guides, wherein the grate is adapted to vertically reposition a center portion of the S-shaped segments of the plurality of infeed guides when the second ends of the infeed guides are vertically repositioned.

10. The converting system of claim 9 , further comprising an elevation cassette changer disposed between the plurality of infeed guides and the converting machine.

11. The converting system of claim 10 , wherein the elevation cassette changer comprises a cassette associated with each of the plurality of infeed guides, and wherein the elevation cassette changer is adapted to change the height of each cassette and the infeed guides associated therewith.

12. The converting system of claim 9 , wherein the plurality of infeed guides comprises a plurality of rows and a plurality of columns of infeed guides.

13. The converting system of claim 9 , wherein the curvature of each S-shaped segment is configured to direct said fanfold material between the first and second ends without creating additional folds, creases, or scores in said fanfold material.

14. The converting system of claim 9 , wherein the grate is adapted to maintain the curvature of each S-shaped segment within a predetermined range during the vertical repositioning of the second ends.

15. The converting system of claim 9 , wherein said plurality of infeed guides are configured to enable said fanfold material to be fed forwards and backwards without creating folds, creases, or scores in said fanfold material and without said fanfold material becoming jammed in the infeed guides.

16. The converting system of claim 9 , wherein the height and vertical orientation of the grate changes as the second ends of the infeed guides are vertically repositioned, whereby a curvature of the S-shaped segments is maintained within a predetermined range as the second ends of the infeed guides are vertically repositioned.

17. A guide system comprising:
a plurality of infeed guides, each of the plurality of infeed guides comprising a first end, a second end, and a S-shaped segment between the first and second ends, the S-shaped segment having a center portion, wherein planar material can be fed between the first and second ends through the S-shaped segments, and wherein the second ends of the infeed guides are adapted for vertical repositioning; and
a frame supporting the plurality of infeed guides, the frame comprising a grate connected to the center portions of the S-shaped segments, wherein the height and vertical orientation of the grate changes as the second ends of the infeed guides are vertically repositioned, whereby the curvature of the S-shaped segments is maintained within a predetermined range as the second ends of the infeed guides are vertically repositioned.

18. The guide system of claim 17 , wherein the frame further comprises one or more pivoting beams from which the grate is suspended.

19. The guide system of claim 18 , wherein each of the one or more pivoting beams has a first end and a second end, the second ends of the one or more pivoting beams being adapted for vertical repositioning, the vertical repositioning of the second ends of the one or more pivoting beams being linked to the vertical repositioning of the second ends of the infeed guides.
