Roll Body Support Device with Nested Core Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll body supporting devices struggle to smoothly feed out and take up roll bodies with large widths due to sagging caused by weight, and require increased size and complexity when supporting multiple roll bodies.
Innovation Solution
A roll body supporting device that includes a shaft member inserted into the core, a shaft outer circumference member, a core support member, and a rotation support section, allowing for rotatable support and adjustable fixation to prevent sagging, with optional features like a rotation driving section and V-block support for simplified configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If both ends of the roll body are supported by fitting sections fitting in core openings, then the roll body can be supported for feeding out, but the center part of the roll body sags due to weight when the roll body has a large width
Solution Approach 1:
The support function is segmented into multiple components: fitting sections at both ends and a core support member inside the core. This segmentation allows each component to perform its specific support function, with the core support member providing internal support to prevent sagging while the fitting sections enable feeding out and taking up.
Solution Approach 2:
The core support member is nested inside the core of the roll body, forming a nested structure. This allows the core support member to be positioned within the core openings and provide internal support to prevent sagging, while the fitting sections at the ends provide external support for feeding operations.
2Adaptability or versatility
If a roll holder supporting both ends of the roll body is provided for each roll body, then each roll body can be individually fed out, but the apparatus size increases
Solution Approach 1:
The shaft member serves multiple functions: it acts as a common support structure for multiple roll bodies, provides core support through the nested core support member, and enables individual feeding of each roll body through the fitting sections. This multi-functionality allows one apparatus to handle multiple roll bodies without requiring separate roll holders for each.

AI summary
A roll body supporting device that rotatably supports a roll body includes a shaft member inserted into a core of the roll body, a shaft outer circumference member fixed to an outer circumference of the shaft member, a core support member that is inwardly in contact with and fits on the core, and a rotation support section that connects the shaft outer circumference member to the core support member and supports the core support member in a manner to be rotatable about the shaft member relative to the shaft outer circumference member.
