CORRUGATED PAPERBOARD BOX MAKING MACHINE AND SHEET FEEDING CONTROL APPARATUS
20180009616 · 2018-01-11 ·

Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

Corrugated Cardboard Pest Repellent System
20230093894 · 2023-03-30 · ·

A corrugated cardboard pest repellent system for repelling and/or exterminating various pests around, within, or between layers of a corrugated cardboard construct while reducing the risk of contamination of goods or exposure by handlers. The corrugated cardboard pest repellent system generally includes one or more liners secured by an adhesive to one or more layers of a corrugated medium that has been treated by a pest repellent. The pest repellent is positioned on the underside of each crest of the one or more layers of the corrugated medium to prevent incursion of pests into the corrugated medium. Multiple layers may be stacked to form various constructs including a single face corrugated cardboard construct, a single wall corrugated cardboard construct, a double wall corrugated cardboard construct, and a triple wall corrugated cardboard construct. The resulting constructs may be utilized for various purposes, including forming various types of containers, padding, or liners.

Controls for paper, sheet, and box manufacturing systems

Systems for providing efficient manufacturing of sheet or box structures, corrugate sheets, or other products of varying size and structure often with pre-applied print (“pre-print”) are provided herein. The systems include various features and modules that enable automated control of the corrugator, including the knives, slitters, scorers and cut-to-mark detection system(s), are contemplated. Colored markings may be used to indicate an order change section between two order sections of a roll plan for the manufacturing process. The colored markings are detected as the corrugator runs and, once detected, a controller determines a next set of order instructions—e.g., to match the upcoming order. Thus, an order change may occur, thereby enabling automated control of the corrugator based on the new order instructions. Computer readable markings may enable checking of the actual position in the roll plan to an intended position, enabling stopping or changing of the corrugator operation if needed.

System and method for producing a facing for a board product with strategically placed scores
11465385 · 2022-10-11 · ·

A system and method for producing a board product made from paper products that have a pre-scored facing in addition to a medium (sometimes called fluting). Conventional corrugated board may feature a cross-corrugated medium and one or more facing that have no score lines that are impressed (at least prior to assembly with the corrugated medium). Such a conventional board product may be inferior because any score lines that are impressed will damage the underlying corrugated medium in some manner. A breakdown in the strength of the underlying medium leads to poor precision when the eventual board product is scored, cut, and folded. A lack of precision in folding a board product leads to gap variation and fishtailing as any articulated portion of the board product may not maintain a precise plane of articulation when folded.

CONTROL PLAN FOR PAPER, SHEET, AND BOX MANUFACTURING SYSTEMS
20220382496 · 2022-12-01 ·

Systems for providing efficient manufacturing of paper, sheet, and/or box products of varying size and structure, often with pre-applied print (“pre-print”), are provided herein. One or more controllers can be used to aggregate orders and information to prepare one or more control plans (e.g., reel maps, reel plans, etc.) for processing a roll of web product through the manufacturing process. The control plan may include a set of instructions for operating one or more systems within the manufacturing process to form the desired finished paper-based product. In such a regard, efficient manufacturing of various paper-based products, including corrugated boxes, folded carton, labels, flexible paper, industrial bags, plates, cups, décor, and many others, can be achieved. Further, efficient customer ordering/tracking, job aggregation, print imposition, corrugator planning, and tracking and adjustments throughout the manufacturing process are contemplated.
