Solution Overview

Problem

Existing automatic splicing devices for connecting carrier tapes from one reel to another do not effectively process the unnecessary sections cut from the tapes, leading to potential damage to the tape indexing device and operational errors.

Innovation Solution

The automatic splicing device incorporates takeup members with apertures and ducts to guide and dispose of the cut unnecessary sections, ensuring they are processed and conveyed away from the conveyance paths, preventing damage and errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the automatic splicing device cuts unnecessary sections from the first and second tapes, then the splicing operation can be performed, but the cut unnecessary sections may get caught in the tape indexing device causing operational defects and damage

Engineering Contradiction:
Improvesplicing operation efficiencyVSAvoidtape indexing device operation reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent extracts the harmful cut unnecessary sections from the system by introducing separate takeup members with apertures that capture and isolate these sections. The first takeup member captures the cut section from the first tape, and the second takeup member captures the cut section from the second tape, preventing them from entering the tape indexing device and causing damage.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The takeup members act as intermediary components between the cutting location and the tape indexing device. These intermediaries capture the cut unnecessary sections and guide them through dedicated conveyance paths with apertures, preventing direct contact with the tape indexing device while maintaining the splicing operation flow.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If the cut unnecessary sections are dropped downward from the device, then simple disposal is achieved, but the sections may get caught in the tape indexing device causing damage

Engineering Contradiction:
Improvedisposal mechanism simplicityVSAvoiddamage to tape indexing device
Core Design Contradiction:
Ease of manufactureVSObject-affected harmful factors

Solution Approach 1:

Instead of simply dropping the cut sections downward in a single dimension, the patent introduces a multi-dimensional disposal path. The takeup members capture sections horizontally, convey them through apertures in specific trajectories, and guide them through ducts to disposal locations, creating a three-dimensional conveyance path that avoids the tape indexing device area.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Reliability

If takeup members with apertures are introduced to process cut sections, then reliable disposal is achieved, but the device complexity increases

Engineering Contradiction:
Improvecut section processing reliabilityVSAvoidsplicing device structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The takeup members serve multiple functions: they capture the cut unnecessary sections, convey them through the apertures, and guide them to disposal locations. This multi-functionality reduces the need for separate components for each operation, thereby limiting the increase in device complexity while achieving reliable cut section processing.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the capture, conveyance, and disposal functions into integrated takeup member assemblies with built-in apertures and ducts. By combining these functions into unified components rather than separate mechanisms, the device complexity increase is minimized while maintaining reliable cut section processing.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Control device 59 moves and positions first and second takeup members 75a and 75b at first and second aperture forming positions Rb1 and Rb2 until the first and second cutting points Q1 and Q2 of the first and second tapes T1 and T2 are positioned at first and second cutting positions Lc1 and Lc2. By doing this, the first and second unnecessary sections Tf1 and Tf2 from first and second tapes T1 and T2 can be processed by reliably being taken into first and second apertures 80a and 80b of first and second takeup members 75a and 75b. Then, after cutting first and second unnecessary sections Tf1 and Tf2, the first and second takeup members 75a and 75b are moved to first and second conveyance positions Ra1 and Ra2. By doing this, the first and second tapes T1 and T2 can be smoothly conveyed along the first and second movable conveyance paths 79a and 79b of the first and second takeup members 75a and 75b to splicing position Ls.
