Brush Filler Bundle Separator with Radial Extension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush stuffing tools face issues with bristle entanglement and wear due to sharp corners in the scraper design, leading to reduced functional reliability and increased maintenance needs.
Innovation Solution
A bundle separator with a blunt scraper end and a radial pick-up extension that protrudes beyond the circular segment-shaped front section, ensuring constant curvature and preventing bristle entanglement by pushing them back into the magazine during forward movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pointed corner scraper design is used to minimize the gap between the scraper and bundle take-up device, then bristle separation is improved, but the scraper is subject to wear and requires considerable expertise and craftsmanship to produce
Solution Approach 1:
Instead of using a pointed corner scraper design that minimizes gap but causes wear and manufacturing complexity, the invention inverts the approach by using a blunt scraper end combined with a radially protruding pick-up extension on the bundle take-up device. This inversion eliminates the need for sharp corners while maintaining effective bristle separation and reducing wear.
Solution Approach 2:
The bundle take-up device is segmented into two functional parts: the main body with the blunt scraper end and the radially protruding pick-up extension. This segmentation allows each part to perform its specific function - the blunt end provides stable contact without wear, while the extension handles the bristle manipulation, simplifying manufacturing of each component.
2Manufacturing precision
If a pointed corner scraper is used to separate bristles closely, then bristle separation precision is improved, but the scraper experiences increased wear and maintenance needs
Solution Approach 1:
The invention inverts the traditional scraper design by replacing the pointed corner with a blunt end. This inversion maintains precise bristle separation through the radially protruding pick-up extension while eliminating the wear problems associated with sharp corners, thereby reducing maintenance requirements.
3Productivity
If the bundle take-up device moves back and forth repeatedly, then bundle transfer functionality is improved, but bristles increasingly become pressed into the space between the scraper end and outer surface
Solution Approach 1:
The radially protruding pick-up extension performs a preliminary action by pressing bristles back into the magazine during the forward movement of the bundle take-up device. This preliminary action prevents bristles from accumulating in the gap between the scraper end and outer surface, maintaining functional reliability during repeated operations.
Solution Approach 2:
The pick-up extension ensures continuous useful action by actively managing bristle positioning during both forward and backward movements of the bundle take-up device. This continuous action prevents bristle entanglement and maintains reliable bundle transfer efficiency over repeated cycles.

AI summary
A bundle separator of a filling tool comprises a bundle taker (20) having an outer side (26) which has a circle-segment-shaped section in front of a recess (28) that receives a bundle, and which has a radially protruding taker protrusion (56) in a rear section (52). The taker protrusion (56) presses bristles that are in contact with a wiper (24) at the end (30) thereof back into a magazine (16).
