Solution Overview

Problem

Existing panel squaring and edge-banding systems are either slow and unsafe due to alternating spindle and edge-banding head operations or fast but inflexible and space-consuming, lacking the ability to produce shaped panels.

Innovation Solution

A method and machine that uses a rotatable member to sequentially position panels at multiple specialized work-stations around a circular series, allowing for high-speed, flexible, and compact edge-banding operations, including milling, edge-taping, and trimming, with a robot or manipulator for loading and unloading.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a multi-tool spindle and edge-banding head alternate to process the panel, then the panel can be processed, but the production speed is very slow

Engineering Contradiction:
Improveproduction speedVSAvoidtime wasted in alternating operations
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The processing system is segmented into multiple specialized work-stations (milling station, edge-banding station, trimming station) arranged in a circular series around the rotatable member. Each station performs a specific operation simultaneously as the panel rotates, eliminating the need for alternating operations and significantly improving production speed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple processing functions (milling, edge-banding, trimming) are merged into a single integrated system where the panel passes through all stations during one rotation. This combines previously separate operations into a unified continuous process, eliminating idle time between operations.

Inventive Principle:
Principle #5Merging (Combining)

2Productivity

If high-speed in-line edge-banders are used, then production speed is fast, but the system occupies entire warehouses and has little flexibility

Engineering Contradiction:
Improveproduction speedVSAvoidspace occupied
Core Design Contradiction:
ProductivityVSArea of stationary object

Solution Approach 1:

The system transitions from a linear in-line arrangement to a circular/rotational configuration. Multiple work-stations are arranged concentrically around a central rotatable member, allowing panels to be processed in a circular path rather than traveling through a long linear sequence. This dramatically reduces the floor space required while maintaining high-speed continuous processing.

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

Solution Approach 2:

The processing path is curved/circular rather than linear. The panel rotates in a circular motion around the central axis, passing through work-stations positioned at different angular positions. This curved configuration compactly packs multiple processing stations into a small radial space, reducing the overall footprint compared to linear arrangements.

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Productivity

If high-speed in-line edge-banders are used, then processing is fast, but the system cannot produce shaped panels, only rectangular ones

Engineering Contradiction:
Improveproduction speedVSAvoidflexibility to produce shaped panels
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system replaces fixed processing paths with a dynamic rotational mechanism. The panel can be rotated to different angular positions, and the rotatable member can be adjusted to accommodate various panel shapes and sizes. This dynamic configuration allows the same equipment to process both rectangular panels and shaped panels with rounded edges or irregular perimeters.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The circular work-station arrangement creates a universal processing system that can handle multiple panel types and operations. The same set of work-stations can process different panel shapes, sizes, and require different sequences of operations (milling, edge-banding, trimming) depending on the specific panel requirements, providing great versatility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of manufacture

If the tail of the tape protrudes from the edge-banding head during processing, then the edge-banding can be applied, but safety issues and jamming occur

Engineering Contradiction:
Improveedge-banding applicationVSAvoidsafety issues and jamming
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

The system introduces an intermediary trimming operation between edge-banding and final panel completion. The trimming station removes excess tape protruding from the panel edges, preventing the tape tail from flailing around like a whip. This intermediary step eliminates safety hazards and potential jamming while maintaining the ease of edge-banding application.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A method for squaring and edge-banding panels is described, with the steps of: - loading a panel onto a member rotatable about a vertical rotation axis; - rotating the rotatable member with predefined angular steps until it completes a complete revolution, - sequentially stopping the panel in front of N processing work-stations, N >= 2, arranged in a circular array around the rotatable member, wherein, during the rotation of the rotatable member, the panel is always held vertical; - as the panel is stopped at the N work-stations, processing the panel edges using panel edge processing units installed at the N work-stations; and - unloading the processed panel from the rotatable member. The method enables high production rates in limited spaces.
