Solution Overview

Problem

Existing splicing devices for tape sections with textile and/or steel wire reinforcement have complex assembly and maintenance due to difficult access to pressure cylinders, leading to high maintenance efforts and long downtimes.

Innovation Solution

Pressure cylinders are attached to the cross connection at the rear and the front fastening sections of the splicing flap, allowing easier access and assembly, with additional features like elastic splicing strips for even force distribution and non-stick coatings for easy tape removal.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If pressure cylinders are mounted on the rear side of the splicing flap, then high pressing force can be applied to achieve form-fitting connection, but assembly and maintenance become very complex due to difficult access

Engineering Contradiction:
Improvepressing forceVSAvoidassembly complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent inverts the conventional mounting location of pressure cylinders from the rear side to the front side of the splicing flap. This inversion allows easy access to the cylinders for assembly and maintenance while still achieving the required pressing force through the flap's mechanical leverage and structural design.

Inventive Principle:
Principle #13The other way round (Inversion)

2Strength

If pressure cylinders are mounted on the rear side of the splicing flap, then high pressing force can be applied, but maintenance and replacement require relatively great effort and long downtimes

Engineering Contradiction:
Improvepressing forceVSAvoidmaintenance effort
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

By inverting the mounting location from rear to front, the pressure cylinders become easily accessible for maintenance activities. The front-side mounting allows maintenance personnel to reach and service the cylinders without disassembling complex rear structures, significantly reducing maintenance effort and device downtime.

Inventive Principle:
Principle #13The other way round (Inversion)

3Device complexity

If the splice flap is made thin to allow tape passage, then the splicing process is simplified, but access to the rear area for pressure cylinder installation becomes even more difficult

Engineering Contradiction:
Improvesplicing mechanism simplicityVSAvoidaccessibility
Core Design Contradiction:
Device complexityVSEase of manufacture

Solution Approach 1:

The thin design of the splice flap is maintained for simplified splicing operations, while the pressure cylinders are mounted on the front side where space is more accessible. This location inversion resolves the accessibility issue created by the thin flap design, allowing both simplicity of splicing and ease of cylinder installation/maintenance.

Inventive Principle:
Principle #13The other way round (Inversion)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Simplifies assembly and maintenance, reduces manufacturing costs, and minimizes maintenance efforts by providing easier access and reducing the complexity of replacing components, while ensuring a durable and precise splicing connection.

Implementation Method 1

the splice flap can be actuated via pressure cylinders in the direction of the contact surface to produce a spliced connection

Methodology Applied
Scientific EffectPressure: Pressure Increase

Implementation Method 2

An elastic splicing strip is preferably arranged on the underside of the splicing flap. With the help of the elastic splicing strip, the pressing forces of the splicing flap are transferred evenly to the edges of the tape sections

Methodology Applied
Scientific EffectElasticity: Elasticity

AI summary

The invention relates to a splicing device (1) for splicing strip sections (7, 11) of a material strip, in particular made of a cord material having a reinforcement of textile and/or beam wires, with a splice flap (14) which is pivotably mounted parallel to its longitudinal axis, wherein the strip sections (7, 11) can be passed between an underside of the splice flap (14) and a contact surface and the splice flap (14) can be actuated via pressure cylinders (40) in the direction of the contact surface to produce a splice connection between two strip sections (7, 11), wherein the pressure cylinders (40) are arranged between a transverse connection (17) and the splice flap (14).To allow easier access for maintenance and replacement, the pressure cylinders (40) are attached at one end to the cross connection (17) on the rear side with respect to the splice flap (14) and at the other end to front mounting sections (28) of the splice flap (14).
