Hopper Deflector for Rod-Shaped Article Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hoppers for rod-shaped articles face challenges in efficiently removing defective or broken articles, which can disrupt the processing flow and require temporary shutdowns.
Innovation Solution
The hopper design incorporates a deflector mechanism at the guiding vane front surface, allowing defective articles to be simply and cost-effectively removed by deflecting them radially away from the hopper.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If detection means and active pushing means are added to remove defective articles, then defective article removal capability is improved, but device complexity increases
Solution Approach 1:
The patent extracts and removes defective articles from the hopper using a simple mechanical deflector that redirects them into a removal channel, eliminating the need for complex detection and active pushing systems while maintaining reliable defective article removal capability
Solution Approach 2:
The hopper design allows defective articles to be removed passively through gravity and geometric guidance, where the deflector automatically redirects defective articles without requiring external detection or actuation systems
2Reliability
If complex electromechanical systems are used for defective article removal, then removal effectiveness is improved, but manufacturing cost increases
Solution Approach 1:
The patent employs simple, inexpensive geometric elements (deflectors and guiding surfaces) made from common materials to achieve effective defective article removal, avoiding costly electromechanical components while maintaining high removal effectiveness
Solution Approach 2:
The system uses passive gravitational flow and geometric guidance to achieve automated defective article removal without expensive sensors, motors, or control systems, significantly reducing manufacturing costs while maintaining effectiveness
3Productivity
If defective articles are not removed, then device complexity remains low, but production rate decreases due to flow disturbances
Solution Approach 1:
The hopper is segmented into distinct functional zones: a main storage chamber, a deflection zone with deflectors, and a separate removal channel, allowing defective articles to be isolated and removed without disrupting the main article flow and maintaining high production rates
Solution Approach 2:
Defective articles are extracted from the main flow through geometric deflection into a separate removal channel, preventing them from causing flow disturbances while maintaining simple device architecture and high productivity
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution effectively eliminates disturbances in the article flow, improves production rates, and enhances manufacturing efficiency by allowing for easy implementation in existing devices without the need for complex electromechanical systems.
Implementation Method 1
a deflector arranged at a front surface of at least one guiding vane. The deflector is for removing a rod-shaped article from the hopper
Implementation Method 2
The guiding channels comprise substantially vertical side walls formed by the guiding vanes and are open along at least a front side such that articles may extend out of the guiding channels and beyond guiding vane front surfaces

AI summary
The invention relates to a hopper for rod-shaped articles having a longitudinal axis. The hopper comprises a plurality of guiding vanes defining adjacent guiding channels in between the guiding vanes, the guiding channels are provided for guiding rod-shaped articles through the hopper in a transport direction transverse to the longitudinal axis of the articles, wherein the guiding channels comprise substantially vertical inner walls formed by the guiding vanes and are open along at least a front side such that articles may extend out of the guiding channels and beyond guiding vane front surfaces. The hopper comprises a deflector arranged at a front surface of at least one guiding vane, the deflector for removing a rod-shaped article from the hopper, which article extends across the front surface of the at least one guiding vane.
