Solution Overview

Problem

Existing banknote bundling machines have complex and costly clamping mechanisms that require high installation precision and generate significant running resistance.

Innovation Solution

A bundled banknote conveying device with a clamping mechanism using a driving motor, transmission device, guide rod, upper jaw, and lower jaw, where the jaws can move vertically to clamp banknotes, and a horizontal transporting mechanism with a guide shaft, guide groove, and guide wheel, reducing installation precision requirements and running resistance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a conventional clamping mechanism with two guide shafts is used, then the banknotes can be clamped and conveyed, but the installation precision requirement is high and the running resistance is significant

Engineering Contradiction:
Improveclamping and conveying functionVSAvoidinstallation precision requirement
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent extracts one guide shaft from the conventional two-guide-shaft configuration, retaining only one guide shaft while adding a guide groove and guide wheel. This reduction in the number of guide shafts directly lowers the installation precision requirements while maintaining the clamping and conveying function through the alternative guiding structure.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If a conventional clamping mechanism with two guide shafts is used, then the banknotes can be clamped and conveyed, but the running resistance is significant

Engineering Contradiction:
Improveclamping and conveying functionVSAvoidrunning resistance
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

By removing one guide shaft from the conventional configuration, the patent reduces the number of contact points and friction sources. The remaining single guide shaft combined with the guide groove and guide wheel creates a smoother guiding path that reduces running resistance while maintaining reliable clamping and conveying operations.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If a complex clamping mechanism is used, then the banknotes can be clamped securely, but the device complexity and cost increase

Engineering Contradiction:
Improveclamping securityVSAvoidmechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent simplifies the clamping mechanism by extracting unnecessary components from the conventional complex design. The essential clamping function is retained through the upper and lower jaws actuated by a driving motor, while eliminating redundant guide shafts and associated mechanisms, thereby reducing overall device complexity and cost.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces complex mechanical linkages with a more straightforward motor-driven system. The driving motor directly actuates the clamping jaws through a simplified transmission mechanism, eliminating the need for complex mechanical systems while maintaining secure clamping of banknotes.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

A conveying device for banknotes to be bundled, comprising: a clamping mechanism, a horizontal transporting mechanism, and a lifting mechanism. The clamping mechanism clamps banknotes to be bundled from a first setting position and conveys same to a second position, the horizontal transporting mechanism horizontally conveys the banknotes to be bundled from the second setting position to a third setting position, and the lifting mechanism lifts the banknotes to be bundled from the third setting position to a fourth setting position. The clamping mechanism comprises a driving motor (1), a transmission device, guide rods (7), an upper jaw (8), and a lower jaw (9), the guide rods (7) being fixedly provided, the upper jaw (8) and the lower jaw (9) passing through the guide rods (7) and being able to freely move in a perpendicular direction within the length range of the guide rods (7); the transmission device is connected between the driving motor (1) and the upper jaw (8) or the lower jaw (9) and drives, by controlling forward rotation and reverse rotation of the driving motor (1), the upper jaw (8) and the lower jaw (9) to clamp banknotes. The clamping mechanism for banknotes to be bundled has a simple structure, is easy to operate, and is low in cost.
