Solution Overview

Problem

Narrowing the installation intervals of tape feeders in surface mounters leads to interference issues during replacement, causing inefficiencies in the tape-feeder replacement operation due to potential misalignment.

Innovation Solution

The component supply apparatus features a feeder installation section with arc-shaped rear ends and guide portions to facilitate smooth insertion and alignment of tape feeders, even with slight misalignment, by increasing the width of the insertion port and using guide plates or bent portions to guide the feeders during installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If tape feeders are arranged at narrower installation intervals to increase the number of feeders for one surface mounter, then productivity and component diversification capability are improved, but interference between feeders occurs during replacement operations due to misalignment

Engineering Contradiction:
ImproveproductivityVSAvoidtape-feeder replacement operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

A guide portion is introduced as an intermediary element between adjacent tape feeders. This guide portion, formed by rounding the corner of the housing at the rear end of each feeder, acts as a mediator that guides the inserting feeder during replacement operations, preventing interference with adjacent feeders while enabling smooth installation at narrow intervals

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The housing corner at the rear end of each tape feeder is rounded to form a guide portion. This curvature design allows the inserting feeder to be guided smoothly during insertion, accommodating slight misalignments and preventing contact interference with adjacent feeders, thereby enabling efficient replacement operations

Inventive Principle:
Principle #14Spheroidality (Curvature)

2Productivity

If tape feeders are arranged at narrower installation intervals, then the number of feeders for one surface mounter is increased, but the insertion port width is reduced causing insertion difficulty

Engineering Contradiction:
Improvenumber of feedersVSAvoidinsertion port width
Core Design Contradiction:
ProductivityVSLength of moving object

Solution Approach 1:

The guide portion formed by rounding the housing corner creates a curved insertion path that effectively increases the usable insertion port width. This curvature allows the inserting feeder to navigate the limited space between adjacent feeders, enabling successful insertion even when the linear distance between feeders is reduced

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Area of stationary object

If tape feeders are arranged at narrower installation intervals, then space utilization is improved, but misalignment during replacement causes contact between feeders

Engineering Contradiction:
Improveinstallation spaceVSAvoidalignment accuracy
Core Design Contradiction:
Area of stationary objectVSReliability

Solution Approach 1:

The rounded guide portion at the housing corner compensates for alignment errors during feeder replacement. The curved surface provides a self-aligning mechanism that guides the inserting feeder into the correct position, preventing contact with adjacent feeders even when slight misalignment occurs

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The guide portion is designed in advance to anticipate and compensate for potential misalignment during feeder replacement. By pre-forming the rounded corner geometry, the system cushions against alignment errors before they can cause interference with adjacent feeders

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

AI summary

It is intended to allow for efficiently performing a feeder replacement operation. A feeder 50 is formed in a shape elongated in one direction to allow a replacement operation therefor to be performed in such a manner that it is inserted and pulled out relative to a feeder installation section 150, along a longitudinal direction thereof. A rear end 111 which is a trailing one of longitudinally opposite ends of each of a plurality of feeders 50A, 50B, ---, in an insertion direction, is provided with a guide portion for guiding one 50C of the feeders to be installed in adjacent relation to ones of the remaining feeders. For example, the guide portion can be formed by rounding corners of the rear end 111 of the feeder 50.
