Solution Overview

Problem

The existing edging systems for wood-based panels face inefficiencies in changing between different edge bands or cassettes, often requiring time-consuming manual handling and rearrangement within the storage unit.

Innovation Solution

A device with a linearly displaceable storage unit allows for direct access to edge bands regardless of their location, eliminating the need for manual rearrangement and handling devices. The device includes a cutting arrangement to sever edge bands at a working position, enabling seamless transitions between edge bands without retracting the previous band.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If a fixed storage unit with manual handling is used, then the device structure is simple, but the time required to change edge bands increases

Engineering Contradiction:
Improvetime required to change edge bandsVSAvoiddevice structure
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The storage unit is made linearly displaceable along the feed direction of the edging machine, transforming it from a static structure to a dynamic one. This allows the storage unit to move to different positions to access different edge band rolls directly, eliminating the need for manual handling and rearrangement, thus reducing the time required to change edge bands while maintaining relatively simple device structure

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The storage unit is arranged vertically with multiple storage locations stacked one above the other. By making the entire storage unit linearly displaceable horizontally along the feed direction, the system adds a new dimension of movement. This allows any vertically stacked edge band roll to be brought into the working position by horizontal displacement, eliminating the need for complex rearrangement mechanisms

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If manual rearrangement within storage unit is required, then the handling device can be simple, but the productivity decreases

Engineering Contradiction:
Improveedge band changing efficiencyVSAvoidease of changing edge bands
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The linearly displaceable storage unit enables operators to directly access any edge band roll by moving the storage unit to the appropriate position. This self-service mechanism eliminates the need for complex manual rearrangement operations or additional handling devices, making the edge band changing process both more efficient and easier to operate

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Multiple edge band rolls are pre-loaded into the storage unit in a vertical stack. The linear displacement mechanism allows the system to bring the required edge band roll to the working position in advance without requiring withdrawal and rearrangement operations, thereby improving productivity and ease of operation

Inventive Principle:
Principle #10Preliminary action

3Loss of time

If edge band must be withdrawn from feed line before changing, then the storage unit structure can be simple, but the loss of time increases

Engineering Contradiction:
Improvetime to withdraw and insert edge bandVSAvoidstorage unit displacement mechanism
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The storage unit is made linearly displaceable along the feed direction, allowing it to move to different positions to access different edge band rolls directly at the working position. This dynamic positioning eliminates the need to withdraw the current edge band from the feed line before inserting a new one, significantly reducing the time required for edge band changes while the displacement mechanism remains relatively simple

Inventive Principle:
Principle #15Dynamics

AI summary

The invention relates to a device (1) for providing edge bands (4), which device comprises a storage unit (3) having individual storage places (7) which are designed to be at least indirectly loaded with edge bands (4), in particular edge bands that each form an edge roller at least in some portions. The storage unit (3) is linearly movably arranged in or on a main frame (2) so that a selected edge roller is movable into a working position in which the edge band (4) located on the edge roller can be accepted by an edge supply (9a) of an edge banding machine (9). A portion of an edge band (4), in particular a portion unwound from an edge roller, can be severed at a cutting position (P1, P2) in the region of the working position by means of at least one cutting assembly (14; 14'; 14'').
