Tape Reel Support with Inclined Rollers for Stable Rotation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing tape reel supporting devices often require the tape reel to be inclined, leading to unstable rotation and potential damage to disk members, which hinders smooth component supply and increases the risk of mechanical issues.

Innovation Solution

A tape reel supporting device with parallel shaft members and externally fitted roller members, where the roller members have inclined surfaces that abut the outer peripheral edges of disk members, allowing for stable perpendicular support of the tape reel regardless of reel width, ensuring it remains rotatable and secure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the tape reel is supported in an inclined state using conventional rack type or roller support type devices, then the tape reel can be accommodated, but the rotation becomes unstable and disk members may be damaged

Engineering Contradiction:

Improverotation stabilityVSAvoidtape reel accommodation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The support device is segmented into multiple shaft members (first, second, and third shaft members) with roller members distributed across them, allowing the tape reel to be supported at multiple discrete points rather than a single continuous surface, thereby achieving both stability and accommodation

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The support structure transitions from a two-dimensional planar support to a three-dimensional spatial arrangement with shaft members positioned at different heights and locations, enabling the roller members to contact the tape reel at multiple points in space for enhanced stability

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Stability of the object's composition

If the tape reel is supported perpendicular to the horizontal plane, then stable rotation is achieved, but conventional supporting devices cannot accommodate various reel widths

Engineering Contradiction:

Improveperpendicular positioning stabilityVSAvoidreel width adaptability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The support device is designed with multiple shaft members and roller members that can accommodate tape reels of various widths by adjusting which roller members engage with the tape reel, allowing a single device to serve multiple reel size configurations while maintaining perpendicular positioning

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The roller members are positioned to be externally fitted into the shaft members, allowing them to move or adjust their positions dynamically to adapt to different reel widths while maintaining the perpendicular support orientation

Inventive Principle:

Principle #15Dynamics

AI summary

A tape reel supporting device includes a plurality of shaft members and a plurality of roller members. The plurality of shaft members extend to be parallel to each other in a horizontal direction. The plurality of roller members are provided to be externally fitted into each of the plurality of shaft members, and each of two inclined surfaces inclined to an axis of each shaft member abuts on an outer peripheral edge of each of a pair of disk members. The two inclined surfaces provided on each of the plurality of roller members are inclined in directions opposite to each other in a direction along an axis of each shaft member on which the roller member is provided.
