Solution Overview

Problem

Existing sheet production systems, particularly for corrugated board, face challenges with braking mechanisms that can damage sheets and are cumbersome when transitioning between different sheet lengths, leading to inefficiencies and production disruptions.

Innovation Solution

A shingling device with independently movable sets of braking wheels that adjust to varying sheet lengths, allowing smooth and gentle deceleration without damaging the sheets, ensuring rapid repositioning for different orders.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If braking brushes are used to slow down sheets by friction, then the sheets can be decelerated, but the sheets may be damaged

Engineering Contradiction:

Improvesheet decelerationVSAvoidsheet damage

Core Design Contradiction:

SpeedVSObject-affected harmful factors

Solution Approach 1:

The patent introduces braking wheels as an intermediary element between the sheet and the braking force. Instead of direct friction contact with brushes that can damage the sheet, the wheels provide a gentler deceleration mechanism that reduces harmful effects on the sheet surface while still achieving the required speed control.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional brush-based friction braking system with a wheel-based mechanical braking system. This substitution changes the interaction mechanism from direct friction (which damages sheets) to a more controlled mechanical engagement (which protects sheets while achieving deceleration).

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Object-affected harmful factors

If braking wheels or rollers are used instead of brushes, then sheet damage is reduced, but the system becomes cumbersome and slow to position when transitioning between orders

Engineering Contradiction:

Improvesheet damageVSAvoidpositioning time

Core Design Contradiction:

Object-affected harmful factorsVSLoss of time

Solution Approach 1:

The braking device is divided into multiple independent braking wheels that can be positioned and adjusted separately. This segmentation allows each wheel to be independently controlled and positioned, enabling faster adjustment when transitioning between different sheet lengths and orders compared to a single cumbersome braking mechanism.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The braking wheels are designed to be movable and adjustable along the conveyor path, allowing dynamic repositioning according to the required sheet length. This dynamic capability enables the system to quickly adapt to different production orders without being bound by a fixed or cumbersome structure.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If a single braking mechanism is used for all sheet lengths, then the device structure is simple, but it cannot quickly adapt to varying sheet lengths in different orders

Engineering Contradiction:

Improvebraking mechanism structureVSAvoidadjustment to varying sheet lengths

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The braking mechanism is segmented into multiple independent wheels that can be individually positioned along the conveyor. This segmentation provides adaptability to different sheet lengths while maintaining relatively simple individual wheel structures, achieving versatility without excessive complexity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The braking wheel system is designed to handle multiple functions: it can brake sheets of varying lengths, adapt to different production orders, and maintain simple individual wheel designs. This multi-functionality achieves both adaptability and structural simplicity simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The shingling device comprises: a shingling conveyor, adapted to receive a stream of sheets aligned with one another and not overlapping; a braking device, positioned above the shingling conveyor and configured to slow down the sheets arriving to the shingling conveyor, and to partially overlap the incoming sheets in shingling fashion. The braking device comprises: a first set of braking wheels aligned with one another along a first rotation axis orthogonal to a feed direction of the sheets to the shingling conveyor; and a second set of braking wheels aligned with one another along a second rotation axis orthogonal to the feed direction of the sheets to the shingling conveyor.
