Stuffing Machine Bundle Remover Single-Direction Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tamping machines for brushes or brooms are limited in cycle rate due to the need for the bundle remover to be accelerated and braked sharply multiple times during its reciprocating motion, resulting in a low average speed and mechanical stress.
Innovation Solution
The bundle collector is designed with multiple receiving notches and driven in a single direction of rotation, allowing simultaneous execution of previously sequential steps, reducing the distance the bundle remover needs to travel and minimizing accelerations and decelerations, while a rotary movement advances the bundle remover to the tufting tool with reduced mechanical load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the bundle take-up unit operates in reciprocating motion with sharp acceleration and deceleration, then the bundle can be transferred between positions, but the cycle rate is limited and mechanical stress increases
Solution Approach 1:
The bundle take-up unit is segmented into multiple bundle-receiving notches (at least two) distributed around its circumference. This allows different notches to be at different positions (take-up position, transfer position, tamping position) simultaneously, enabling continuous operation without waiting for a single notch to complete the full reciprocating cycle. The segmentation of the take-up unit into multiple functional zones resolves the contradiction by allowing parallel operations.
Solution Approach 2:
Instead of moving the bundle take-up unit back and forth in reciprocating motion, the invention inverts the approach by rotating the unit in a single direction. The bundle-receiving notches are arranged circumferentially, and the unit rotates to bring different notches to the required positions. This unidirectional rotation eliminates the need for sharp acceleration and deceleration cycles, thereby increasing average speed and cycle rate while reducing mechanical stress.
2Productivity
If the bundle take-up unit travels the full distance between take-up and tamping positions repeatedly, then bundle transfer is achieved, but the travel distance and time are maximized
Solution Approach 1:
The invention transitions from linear reciprocating motion to rotational motion in a different dimensional approach. By arranging bundle-receiving notches around the circumference of the take-up unit and rotating it, the system utilizes angular position rather than linear back-and-forth movement. This dimensional change allows multiple notches to access different positions simultaneously, reducing the effective travel distance required per cycle and increasing productivity.
