Abstract
The present invention relates to systems and processes for cutting and creasing corrugated cardboards, and more specifically, to digital system and processes for cutting and creasing corrugated cardboards, wherein the system includes an array of cutting elements that can be dynamically configured to cut and/or crease a wide range of contours.
Claims15
A cutting-and-creasing system configured to form a predetermined pattern of cuts and creases within a cardboard, comprising:
- a) a conveyer supporting the cardboard;
- b) a cardboard-motion-control unit configured to control the motion of said conveyer in a first direction;
- c) at least one punching head unit including an array of punching elements that are individually and selectively actuatable by a punching-control-unit to move axially with a distal tip that faces said cardboard, between a withdrawn position and a cutting position, wherein said punching head unit is firmly held such that said punching elements are orthogonal to the cardboard;
- wherein said punching elements are distributed in a selected areal pattern within said array having said first direction and a second direction;
- said second direction is perpendicular to said first direction;
- said punching-control-unit is preconfigured to timely perform a punching step, the punching step includes moving one or more of said punching elements from said withdrawn position to said cutting position, relative to said conveyer, and immediately withdrawing said one or more of said punching elements to said withdrawn position, to thereby form through holes across said cardboard, or non-through holes, or cuts;
- a cut line is formed by a respective cluster of overlapping said through holes;
- and
- a crease line is formed by a respective cluster of either non-overlapping said through holes, or either overlapping or non-overlapping said non-through holes, or cuts;
- d) a cutting-and-creasing-bridge carrying said at least one punching head unit;
- and
- e) a bridge-motion-control module for moving said cutting-and-creasing-bridge in said first direction and in an orthogonal direction perpendicular to both said first direction and said second direction,
- wherein each said movable punching element comprises a nozzle at a punching end thereof to emit a lubricating agent to thereby locally reduce friction with the cardboard substrate before a cutting operation by said punching element.
