Pallet Loading Receiving Elements with Independent Lifting Drives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pallet loading devices have reduced performance due to a common lifting drive for both receiving elements, resulting in longer cycle times and lower efficiency in loading pallets.
Innovation Solution
The receiving elements are equipped with independent lifting drives, allowing for separate control of vertical strokes, which enables them to move more efficiently during the transfer and placement of cargo layers, reducing overall cycle time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a common lifting drive is used for both receiving elements, then the device structure is simpler, but the cycle time increases and productivity decreases
Solution Approach 1:
The common lifting drive is segmented into two independent lifting drives, one for each receiving element. This allows the receiving elements to move independently, enabling parallel operations and reducing the overall cycle time for transferring cargo layers to pallets.
Solution Approach 2:
The second receiving element is positioned in advance at the transfer position during the work cycle of the first receiving element. This preliminary positioning allows the system to overlap operations, reducing idle time and improving productivity without significantly increasing structural complexity.
2Productivity
If the second receiving element moves to intermediate position and transfer position during each work cycle, then the transfer efficiency improves, but the device complexity increases
Solution Approach 1:
The control system is segmented into independent control units for each receiving element, allowing each element to execute its movement sequence (ready position → intermediate position → transfer position) independently. This modular control approach manages complexity while enabling efficient parallel operations.
Solution Approach 2:
The receiving elements employ dynamic positioning with multiple discrete positions (ready, intermediate, transfer) that can be adjusted based on the work cycle phase. This dynamic adaptability optimizes transfer efficiency while the control system manages the complexity through standardized position protocols.
