Solution Overview

Problem

Existing machinery for emptying trays filled with rod-like articles in the tobacco industry lacks the ability to optimize the path and derivatives of motion, such as speed and acceleration, which affects the efficiency and fluidity of the unloading process, particularly when handling both four-wall and five-wall trays with different rigidity and material properties.

Innovation Solution

A handling module and apparatus that incorporates a turning unit capable of rotating the tray during lifting, with gripping members that can move transversely to the axis of rotation, allowing for complex movements including elliptical paths, and an opening mechanism for five-wall trays, enabling precise control over the unloading process without mechanical adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the tray is turned and lifted separately using different mechanisms, then the unloading process can be completed, but the motion path cannot be optimized and the derivatives of motion (speed, acceleration) cannot be controlled

Engineering Contradiction:
Improveunloading efficiencyVSAvoidmechanism complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent combines the turning mechanism and lifting mechanism into a single integrated handling module. The turning unit rotates the tray while the lifting unit simultaneously elevates it, merging two separate operations into one coordinated action. This integration allows optimization of the motion path and control of motion derivatives without requiring separate mechanisms for each function.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent implements dynamic control of the handling module where the turning and lifting operations are coordinated through controlled motion along an elliptical path. The system dynamically adjusts speed and acceleration profiles during the combined turning-lifting operation, optimizing the motion derivatives for efficient unloading while maintaining control over the tray and its contents.

Inventive Principle:
Principle #15Dynamics

2Productivity

If the apparatus is adapted for specific tray types (four-wall or five-wall), then the unloading process can be optimized for that tray type, but the apparatus cannot handle different tray types without mechanical adjustments

Engineering Contradiction:
Improveunloading efficiencyVSAvoidtray type adaptability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent designs the handling module with universal gripping members that can accommodate both four-wall rigid trays and five-wall cardboard trays. The gripping members are configured to securely hold different tray types without requiring mechanical adjustments or reconfiguration of the apparatus. This multi-functional design allows the same apparatus to efficiently handle various tray types used in the tobacco industry.

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

3Ease of operation

If the tray is moved along a simple path, then the mechanism is simpler, but the motion cannot be optimized for fluidity and precision

Engineering Contradiction:
Improvemotion fluidityVSAvoidpath control complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs an elliptical motion path for the combined turning and lifting operation instead of simple linear or circular paths. This curved elliptical trajectory optimizes the motion fluidity and precision during tray transport and unloading. The elliptical path allows smooth transitions between turning and lifting phases, enhancing operational ease while the path is controlled through the coordinated action of the integrated mechanisms.

Inventive Principle:
Principle #14Spheroidality (Curvature)
