Solution Overview

Problem

Existing packaging machines require significant time and labor for setup adjustments to accommodate different packaging bags, leading to downtime and increased risk of incorrect settings, particularly in HFFS machines with rotary setups.

Innovation Solution

A packaging bag receiving apparatus with a distance adjusting device that allows simultaneous or concurrent adjustment of holder pairs to accommodate various bag sizes, featuring displaceable holders and transmission strands for synchronized movement, enabling efficient and reliable setup.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If individual setup of each receiving or holding apparatus is performed, then each apparatus can be adjusted to the required position, but the setup time and labor increase significantly

Engineering Contradiction:

Improvepositioning accuracy of holder pairsVSAvoidsetup time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent combines the adjustment mechanism of multiple holder pairs into a single integrated distance adjusting device. This device can simultaneously adjust the distance between multiple holder pairs through a common adjustment mechanism, eliminating the need to individually adjust each holder pair and thereby significantly reducing setup time while maintaining positioning accuracy.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The distance adjusting device serves multiple functions: it can adjust the distance between different holder pairs, accommodate various packaging bag sizes, and maintain proper positioning for different product types. This multi-functional design eliminates the need for separate adjustment procedures for each holder pair, addressing both the time loss and positioning accuracy requirements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Manufacturing precision

If individual adjustment of each holder pair is performed, then correct positioning can be achieved, but the risk of incorrect settings increases

Engineering Contradiction:

Improvepositioning accuracy of holder pairsVSAvoidrisk of incorrect settings

Core Design Contradiction:

Manufacturing precisionVSReliability

Solution Approach 1:

By merging the adjustment control into a single distance adjusting device that simultaneously controls multiple holder pairs, the patent ensures that all holder pairs are adjusted consistently and correctly. This unified control mechanism eliminates the risk of inconsistent or incorrect settings that would occur with individual adjustments, while still achieving the required positioning accuracy for different packaging bag sizes.

Inventive Principle:

Principle #5Merging (Combining)

3Device complexity

If holder pairs are fixed at predetermined distances, then the machine structure is simplified, but the adaptability to different packaging bags is reduced

Engineering Contradiction:

Improvestructure complexity of receiving apparatusVSAvoidadaptability to different packaging bag sizes

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a dynamic adjustment capability to the holder pairs through the distance adjusting device. Instead of fixed predetermined distances, the holder pairs can be dynamically adjusted to different distances according to the specific packaging bag sizes being processed. This dynamic mechanism maintains relatively simple overall structure while significantly improving adaptability to various packaging requirements.

Inventive Principle:

Principle #15Dynamics

4Productivity

If comprehensive adjustment of all receiving apparatus is performed, then all apparatus can be optimized for the current packaging task, but the machine downtime increases

Engineering Contradiction:

Improveproduction efficiencyVSAvoidmachine downtime

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent merges the adjustment function into a single distance adjusting device that can optimize multiple holder pairs simultaneously. This allows comprehensive adjustment of all receiving apparatus to be performed in one operation rather than requiring separate adjustment cycles for each apparatus, thereby optimizing production efficiency while minimizing machine downtime.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The distance adjusting device enables preliminary adjustment of all holder pairs before the packaging process begins. By performing comprehensive adjustment in advance through the unified adjustment mechanism, the system ensures all apparatus are optimized for the current packaging task without requiring interruptions during production, thus reducing overall machine downtime.

Inventive Principle:

Principle #10Preliminary action
