Solution Overview

Problem

The existing folding box gluing machines face challenges in efficiently embossing Braille on folding boxes without interfering with other production steps, particularly due to high tool costs and difficulties in embossing Braille near crease lines, which increases setup time and tool complexity.

Innovation Solution

A folding box gluing machine is equipped with a rotary embossing device that can emboss Braille between processing stations, using a pair of rotating tools driven by a servomotor, allowing for independent positioning and application of Braille without affecting the creasing lines, and can be easily integrated or removed based on production needs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If Braille embossing is integrated into the die cutting process, then Braille can be embossed on blanks, but tool costs increase and setup time increases due to requiring separate tools for each blank

Engineering Contradiction:
ImproveBraille embossing capabilityVSAvoidtool requirements
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines the Braille embossing function with the existing crease line embossing tools in the folder-gluing machine. Instead of using separate tools in the die cutter, the invention uses the same embossing tools that create crease lines to also emboss Braille characters, thereby reducing tool requirements and setup time while maintaining Braille embossing capability

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The embossing tools in the folder-gluing machine are designed to serve multiple functions: creating crease lines and embossing Braille characters. This multi-functionality eliminates the need for dedicated Braille embossing tools in the die cutting process, reducing both tool complexity and setup time

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

2Adaptability or versatility

If Braille embossing is done near crease lines in the die cutter, then Braille can be applied to blanks, but the process interferes with die cutting and increases setup time

Engineering Contradiction:
ImproveBraille embossing capabilityVSAvoidproduction efficiency
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent extracts the Braille embossing operation from the die cutting process and relocates it to the folder-gluing machine. This separation eliminates interference between Braille embossing and die cutting operations, allowing both processes to proceed efficiently without mutual interference

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention performs Braille embossing after the blanks have been die-cut and are being prepared in the folder-gluing machine. This preliminary action ensures that the blanks are ready for final assembly, and Braille is embossed at the optimal time without affecting the die cutting process

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple embossing tools are used for different blanks, then each blank can have custom Braille, but tool complexity and setup time increase significantly

Engineering Contradiction:
Improvecustom Braille capabilityVSAvoidsetup time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The folder-gluing machine uses universal embossing tools that can emboss Braille on all blank types. Instead of having dedicated tools for each blank format, the same tools are used for all blanks, significantly reducing setup time while maintaining the ability to produce custom Braille as needed

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

AI summary

The machine has conveying belts (3, 4) arranged to deliver blanks through an orienting station (1) and a pre-breaker station (2). A rotational embossing mechanism (6) includes rotating driven upper and lower dies (7, 8) arranged between the stations so as to emboss the blanks. The embossing dies are mounted in the machine and are positioned in a crosswise direction. The dies are constructed to produce a script for the blind. The die (7) includes a product-specific male mold and the die (8) includes a product-neutral female mold. Positions of the dies are adjustable relative to each other.
