Palletizing Device Cardboard Sheet Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Palletizing devices experience inefficiencies due to significant waiting times for depositing subsequent layers of products on pallets and positioning cardboard sheets, leading to reduced overall efficiency and stability in the palletizing process.
Innovation Solution
Incorporation of a positioning organ with a gripping system and storage plane for cardboard sheets, allowing for simultaneous handling and positioning of sheets on the first layer of products, reducing waiting times and improving stability and efficiency by enabling continuous operation without interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single cardboard sheet collecting and positioning turret is used, then the device complexity is reduced, but the productivity decreases due to waiting times for sheet positioning
Solution Approach 1:
The patent divides the cardboard sheet handling function into multiple independent turrets, each capable of collecting and positioning sheets autonomously. This segmentation allows parallel operation of multiple turrets, eliminating the sequential waiting time that occurs with a single turret and thereby increasing productivity while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent implements preliminary positioning of cardboard sheets by having multiple turrets prepare and hold sheets in advance before they are needed for palletizing. This preliminary action eliminates waiting time during the actual palletizing process, as sheets are already positioned and ready for immediate application, thus improving productivity without significantly increasing complexity.
2Stability of the object's composition
If the upper platform waits for the follower platform to return with new products, then the stability of the palletizing process is maintained, but the productivity decreases due to dead time
Solution Approach 1:
The patent implements preliminary positioning of cardboard sheets by having multiple turrets prepare and hold sheets in advance before they are needed for palletizing. This preliminary action eliminates waiting time during the actual palletizing process, as sheets are already positioned and ready for immediate application, thus improving productivity without significantly increasing complexity.
Solution Approach 2:
The patent enables continuous operation of the palletizing device by having multiple cardboard sheet turrets operate in parallel or alternately, ensuring that a sheet is always ready for application regardless of the follower platform's position. This continuity eliminates dead time and maintains steady productivity while preserving process stability through coordinated turret operation.
3Productivity
If multiple cardboard sheet turrets are used, then the productivity increases by eliminating waiting times, but the device complexity increases
Solution Approach 1:
The patent divides the cardboard sheet handling function into multiple independent turrets, each capable of collecting and positioning sheets autonomously. This segmentation allows parallel operation of multiple turrets, eliminating the sequential waiting time that occurs with a single turret and thereby increasing productivity while maintaining manageable device complexity through modular architecture.
Solution Approach 2:
The patent designs the multiple cardboard sheet turrets to be self-sufficient, with each turret independently collecting, holding, and positioning sheets without requiring constant intervention from other system components. This self-service capability reduces the need for complex coordination mechanisms and control systems, thereby limiting the increase in device complexity while maximizing productivity benefits.
