Drafting unit with a load carrier as well as a load carrier for a drafting unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing textile machine drafting systems face difficulties in accessing and replacing upper roller bodies, leading to increased downtimes due to wear and tear, as the rollers are hard to reach and maintain.
Innovation Solution
A load carrier with a top roller body that has an actuating section protruding beyond the support arm, allowing for easy grasping and removal, and a holding device with brackets that secure the roller body, enabling tool-free inspection, replacement, and adjustment, with optional spring-loaded clamps for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the upper roller body is mounted close to the support arm structure, then the structural compactness is improved, but the accessibility for maintenance and replacement deteriorates
Solution Approach 1:
The upper roller body is segmented into a functional rolling section and a separate actuating section. The actuating section protrudes beyond the support arm and can be grasped independently, allowing maintenance personnel to access and manipulate the roller body without needing to reach into the compact internal structure of the drafting unit.
2Reliability
If the upper roller body is securely fixed on the support arm, then the operational reliability is improved, but the ease of replacement deteriorates
Solution Approach 1:
The actuating section is extracted from the main roller body structure and extended beyond the support arm. This extracted section serves as a dedicated interface for removal and installation operations, allowing the roller body to remain securely mounted during operation while being easily removable when maintenance is required.
3Volume of moving object
If the roller body is positioned within the support arm structure, then the space utilization is improved, but the operational efficiency for maintenance deteriorates
Solution Approach 1:
The actuating section extends the roller body interface into a different spatial dimension - protruding laterally beyond the support arm structure. This dimensional extension allows maintenance personnel to access the roller body from the side without needing to disassemble the compact drafting unit structure, significantly improving maintenance efficiency.

AI summary
The invention relates to a drawing unit with a load carrier and a load carrier for a drawing unit for drawing a fiber ribbon at a work station of a textile machine, comprising a support arm and an upper roller body detachably mounted on a holding device connected to the support arm. To provide a drawing unit with a load carrier and a load carrier for a drawing unit for drawing a fiber ribbon at a work station of a textile machine that can be inspected, repaired, and/or adapted to the fiber ribbon material to be drawn in a user-friendly manner, and in particular to allow for easy replacement of the upper roller bodies, it is provided that the upper roller body has an actuating section projecting beyond the support arm in the longitudinal direction of the upper roller body.
