Solution Overview
Problem
Current automatic palletizing systems face challenges in efficiently stacking packages of varying sizes and shapes without manual intervention, as they require complex calculations for stability and unloading sequences, and existing technologies are limited in throughput and flexibility.
Innovation Solution
The use of a movable intermediate plate and adjustable lateral walls allows for flexible stacking on a conveyor system, enabling efficient transfer and wrapping of packages onto carriers of different sizes, with a modular pusher and sliding plate arrangement for precise positioning and simultaneous handling of multiple packages.

Engineering Contradiction Analysis
1Productivity
If packages of different characteristics are stacked automatically, then productivity increases through automated handling, but device complexity increases due to the need for sophisticated control systems to calculate stability and unloading sequences
Solution Approach 1:
A positioning table is introduced as an intermediary device between the package supply and the final stack. Packages are positioned on this table first, then transferred to the stack in a controlled manner. This intermediary structure simplifies the control requirements by providing a stable intermediate platform for package arrangement.
Solution Approach 2:
The stacking process is divided into distinct phases: package positioning on the positioning table, then transfer to the final stack position. This segmentation allows each phase to be controlled independently, reducing the overall control complexity while maintaining automated operation.
2Manufacturing precision
If packages are positioned precisely on a positioning table before stacking, then stacking precision improves, but the time required for each stacking operation increases
Solution Approach 1:
Packages are positioned on the positioning table in advance before the actual stacking operation. This preliminary positioning ensures that when packages are transferred to the final stack, they are already in the correct positions, eliminating the need for time-consuming adjustments during the stacking process itself.
Solution Approach 2:
The positioning table allows multiple packages to be positioned simultaneously or in parallel, rather than sequentially. This continuous positioning action reduces the total time required while maintaining precision, as the positioning and transfer operations can overlap.
3Manufacturing precision
If a positioning table is used for precise package placement, then stacking accuracy improves, but device complexity and space requirements increase
Solution Approach 1:
The positioning table serves multiple functions: it acts as a temporary storage surface, a positioning platform, and a transfer mechanism. This multi-functionality reduces the need for separate dedicated components for each function, thereby simplifying the overall device structure while maintaining positioning accuracy.
4Productivity
If packages are stacked in a fixed arithmetic pattern, then stacking speed increases, but adaptability to different package characteristics decreases
Solution Approach 1:
The system transitions from fixed arithmetic patterns to dynamic positioning based on actual package characteristics. Sensors detect package dimensions and properties, and the control system adjusts positioning instructions in real-time, allowing the system to adapt to varying package types while maintaining efficient stacking operations.
