Carousel Brush Holder Layout for Compact High-Speed Broom Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brush drilling and packing machines struggle to achieve high cycle rates and compact design, particularly for elongated brushes like brooms, due to the need for precise, multi-directional movement of holders and significant moving masses, which limits efficiency and space utilization.
Innovation Solution
A method and machine design that utilizes a carousel with holders aligned parallel to the central axis, employing two separate drives for pivoting movements around parallel axes of rotation to minimize moving masses and increase compactness, allowing for efficient drilling and packing of elongated brushes by aligning brush bodies laterally and longitudinally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If brush bodies are aligned with their longitudinal axis in the circumferential direction of the carousel, then the machine can process multiple brushes simultaneously, but the moving masses become significant and the machine size increases
Solution Approach 1:
Instead of aligning brush bodies with their longitudinal axis in the circumferential direction (conventional approach), the invention inverts the orientation by aligning the longitudinal axis parallel to the central axis of the carousel. This inversion allows brushes to be positioned radially inward, significantly reducing the radius of rotation and thus the moving masses, while maintaining multi-position processing capability
2Manufacturing precision
If holders are moved precisely in at least two spatial directions at high speed between drilling and tamping cycles, then angled bristle tufts can be achieved, but the machine complexity and space requirements increase
Solution Approach 1:
The invention introduces a radial dimension for holder movement by allowing holders to move along the radial direction of the carousel in addition to the circumferential direction. This dimensional change enables precise positioning for angled bristle tufts while using the carousel's rotational motion to simplify the overall positioning mechanism, reducing complexity compared to traditional multi-axis linear movement systems
3Volume of moving object
If the carousel radius is reduced to minimize moving masses, then compactness is achieved, but the number of holes that can be processed simultaneously is limited
Solution Approach 1:
The invention segments the hole processing into multiple circumferential positions around the carousel, with each position equipped with drilling and tamping tools. This segmentation allows simultaneous processing of multiple holes at different angular positions while maintaining a compact radial footprint, effectively increasing productivity without increasing the carousel radius

AI summary
The invention relates to a method for producing elongate brushes, in particular brooms, and to a corresponding brush drilling and stuffing machine, wherein a carousel (12) is used, on which a plurality of holders (16) for brush bodies (18) are mounted. The brush bodies (18) are fastened in such a way that their direction of width (B) is oriented in the circumferential direction of the carousel (12). The movement in the direction of width (B) is carried out by two separate rotational axes (14, 34).
