Corrugated Board Rotary Tool Positioning for Faster Changeovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing corrugated board production systems face challenges in quickly and precisely positioning rotary tools for cutting and scoring due to complex and slow positioning mechanisms, which hinder efficient changeovers between small production orders.
Innovation Solution
A device for longitudinal processing of corrugated board webs featuring a manipulator system with adjustable slides and engaging members that allows for rapid positioning of rotary tools along a transverse adjustment guide, enabling simultaneous engagement and release of multiple tools for faster order changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a complex positioning mechanism with nut screws and threaded rods is used to position rotary tools, then the tools can be positioned along the feed path, but the positioning process becomes slow and complex
Solution Approach 1:
The patent extracts and removes the complex nut screw and threaded rod positioning mechanisms from the system. Instead, it uses a simplified carriage-mounted tool holder system where tools are directly positioned on carriages that move along the feed path without requiring complex mechanical positioning components.
Solution Approach 2:
The patent segments the positioning function by using individual carriages for each tool holder, allowing independent positioning and movement of each tool along the feed path. This segmentation eliminates the need for a single complex positioning mechanism and enables parallel operation of multiple tools.
2Measurement precision
If a complex positioning mechanism with nut screws and threaded rods is used to position rotary tools, then the tools can be positioned along the feed path, but the positioning speed becomes slow
Solution Approach 1:
The patent removes the slow nut screw and threaded rod positioning mechanisms and replaces them with a faster carriage-based system where tool holders are mounted on carriages that can be quickly positioned and secured along the feed path using simple locking mechanisms.
Solution Approach 2:
The patent implements dynamic positioning by allowing carriages to be freely positioned along the feed path and then dynamically locked into place. This enables rapid repositioning of tools by simply moving and securing carriages rather than operating complex mechanical positioning systems.
3Adaptability or versatility
If multiple tool-holder slides with individual nut screws are used, then each tool can be positioned independently, but the overall system complexity increases
Solution Approach 1:
The patent segments the tool positioning system into independent carriages, each carrying one or more tool holders. Each carriage can be independently positioned and locked along the feed path, providing independent tool positioning without requiring individual nut screws and threaded rods for each tool.
Solution Approach 2:
The patent merges multiple tool holders onto single carriages, allowing multiple tools to be positioned and secured together. This combining approach reduces the number of individual positioning mechanisms needed while maintaining independent positioning capability through the carriage system.

AI summary
The device includes a feed path of the corrugated board web. A first series of rotary tools is provided on a first side of the feed path of the corrugated board web, each supported by a respective slide slidably engaged with a first adjustment guide and adjustable along the first adjustment guide. The first adjustment guide extends in a direction transverse to the feed direction of the corrugated board along the feed path. A first manipulator adapted to position the slides of the first series of rotary tools along the first adjustment guide is slidably engaged with the first adjustment guide and is movable therealong.
