Solution Overview

Problem

Existing systems for separating workpieces, such as panels in the woodworking industry, face challenges in achieving reliable and high cycle rates, especially with thin, flexible materials, often resulting in unsafe processes due to incomplete separation.

Innovation Solution

A device with an infeed system that decouples workpiece holding from ejection, utilizing first and second infeed elements arranged at the edges and between them, along with a suction device and revolving conveyor, to ensure stable and precise separation at high speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If a belt is used to convey the bottom workpiece from the magazine, then the workpiece can be conveyed, but the adjacent workpiece is also conveyed and singulation cannot be achieved

Engineering Contradiction:
Improveconveying capabilityVSAvoidsingulation reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The conveying system is segmented into multiple independent elements (first conveying elements at edges, second conveying element in the middle) that can be controlled separately. This segmentation allows selective engagement with the workpiece to achieve reliable singulation while maintaining conveying capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the conveying system have different functions: first conveying elements at edges provide support and stability, while the second conveying element in the middle provides the primary conveying force. This local differentiation enables both reliable singulation and continuous conveying.

Inventive Principle:
Principle #3Local quality

2Stability of the object's composition

If infeed elements are arranged only at the edges of the magazine area, then stable feeding is achieved, but workpiece deflection occurs leading to premature ejection

Engineering Contradiction:
Improvefeeding stabilityVSAvoidejection timing control
Core Design Contradiction:
Stability of the object's compositionVSReliability

Solution Approach 1:

The infeed system is divided into first infeed elements at edges for support and a second infeed element in the middle for controlled engagement. This segmentation provides both stability during feeding and controlled timing for ejection, preventing premature release.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The second infeed element acts as an intermediary between the edge elements and the workpiece center, providing controlled support that prevents deflection while enabling timely ejection. This intermediary element coordinates the transition from stable feeding to controlled discharge.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If the feeding device and discharge device are integrated, then the system is simpler, but the operation cannot be decoupled from magazine conditions

Engineering Contradiction:
Improvesystem integrationVSAvoiddischarge speed independence
Core Design Contradiction:
Device complexityVSProductivity

Solution Approach 1:

The system is segmented into a feeding device that handles magazine interaction and a discharge device that handles high-speed ejection. This functional segmentation allows the discharge device to operate independently at high speeds while the feeding device manages magazine conditions, resolving the contradiction between simplicity and speed independence.

Inventive Principle:
Principle #1Segmentation
