Solution Overview

Problem

Existing solutions for dividing stacks of flat-folded cartons into manageable and equal-sized stacks for efficient handling and packaging are inefficient, often resulting in misalignment and damage due to uneven pressure distribution and lack of precise separation methods.

Innovation Solution

A divider system comprising a tiltable magazine, a pusher member, and a holder foot that compresses and aligns the carton pack, creating a low-density area for precise separation, using a parting tip and support finger to ensure reliable and well-defined stack formation, allowing for the creation of multiple stacks of equal size.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If flat-folded cartons are loaded into magazines in large groups (50-100 cartons) to stabilize the stack, then the magazine buffer capacity is improved, but the stack may twist and displace due to incomplete flat-folding

Engineering Contradiction:
Improvenumber of flat-folded cartons in magazineVSAvoidstack stability
Core Design Contradiction:
Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The divider performs preliminary separation of the carton pack into smaller stacks before loading into the magazine. By dividing the large pack into manageable stacks of optimal size (e.g., 50-100 cartons), the system prepares the cartons in advance for stable magazine operation, preventing twisting and displacement while maintaining adequate buffer capacity.

Inventive Principle:
Principle #10Preliminary action

2Device complexity

If the number of flat-folded cartons in the magazine is kept low to reduce pressure on lower cartons and device size, then the feeding device size is reduced, but the stack becomes unstable and prone to twisting

Engineering Contradiction:
Improvefeeding device sizeVSAvoidstack stability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The divider segments the large pack of flat-folded cartons into multiple smaller stacks of optimal size before magazine loading. This segmentation allows each stack to be stable and manageable, preventing twisting and displacement while keeping the magazine and feeding device compact and simple in structure.

Inventive Principle:
Principle #1Segmentation

3Productivity

If flat-folded cartons are delivered in large packs to optimize transport economy, then the transport efficiency is improved, but the packs cannot be optimally loaded into magazines or handled by loading machines

Engineering Contradiction:
Improvetransport efficiencyVSAvoidloading operation
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The divider performs preliminary division of large transport packs into magazine-optimal stacks before the loading operation. This advance segmentation maintains the transport efficiency benefits of large packs while preparing cartons in advance for optimal magazine loading, making the subsequent loading operation simple and efficient.

Inventive Principle:
Principle #10Preliminary action

4Productivity

If existing separation methods are used to divide carton packs, then separation is achieved, but misalignment and damage occur due to uneven pressure distribution and lack of precise separation

Engineering Contradiction:
Improveseparation speedVSAvoidstack alignment precision
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The divider applies localized compression through a pusher member that exerts pressure on a specific portion of the carton pack, and uses a holder foot to support a specific side of the pack. This localized action creates precise separation planes and maintains alignment, preventing misalignment and damage while achieving efficient separation.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The holder foot acts as an intermediary element between the pusher member and the carton pack, providing controlled support during the separation process. This intermediary mechanism ensures even pressure distribution and precise separation, preventing damage and misalignment while maintaining separation efficiency.

Inventive Principle:
Principle #24Intermediary (Mediator)
