Solution Overview

Problem

Existing packaging arrangements and methods for stacking and removing objects from pallets require extensive horizontal space, multiple moving parts, and result in inefficient vertical strokes, leading to slow operation and increased space occupation.

Innovation Solution

A packaging apparatus and method where the pick-up member engages pallets from above, allowing for limited vertical strokes and simultaneous use of lifting devices to position pallets efficiently, enabling compact operation and speed gains by using suction cups and a wrapping mechanism that adapts to each layer for secure packaging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a separate robot is used to remove pallets from a stacked store, then pallet removal can be automated, but the device complexity increases and horizontal space requirement increases

Engineering Contradiction:
Improvepallet removal automationVSAvoidnumber of robots
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The pick-up member is designed to perform multiple functions: it both stacks objects onto pallets and removes pallets from the stacked store. This multi-functionality eliminates the need for a separate robot dedicated to pallet removal, thereby reducing device complexity while maintaining automation.

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

2Ease of operation

If pallets are presented at a low loading position, then the robot can easily load objects, but the vertical space occupation increases and operation speed decreases

Engineering Contradiction:
Improveobject loading easeVSAvoidoperation speed
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

The pallet is pre-positioned on the support at an optimized height before the object stacking begins. This preliminary positioning ensures that the pick-up member operates within a limited vertical stroke range, increasing operation speed while maintaining ease of loading.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If the pick-up member has a large vertical stroke to reach low loading position, then pallets can be loaded, but the operation speed decreases

Engineering Contradiction:
Improvepallet loading capabilityVSAvoidoperation speed
Core Design Contradiction:
Ease of operationVSSpeed

Solution Approach 1:

The support is positioned in advance at an optimal height so that the pick-up member only needs to perform a limited vertical stroke to engage and manipulate the pallet. This pre-positioning eliminates the need for large vertical movements during the loading operation, thereby increasing speed.

Inventive Principle:
Principle #10Preliminary action

4Extent of automation

If lifting fingers are used to dispense pallets, then pallets can be removed from stacked store, but the control complexity increases to account for pallet height deviations

Engineering Contradiction:
Improvepallet dispensing automationVSAvoidcontrol system complexity
Core Design Contradiction:
Extent of automationVSDevice complexity

Solution Approach 1:

The pick-up member engages the pallet from above in a manner that is insensitive to variations in pallet height. The engagement mechanism automatically adapts to the actual pallet position without requiring complex control systems to compensate for height deviations, thereby simplifying the control system while maintaining automation.

Inventive Principle:
Principle #25Self-service
