Transportable Wrapper Stacker Machine for Pallet Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wrapping and storage machinery lacks a solution for efficiently retaining and stacking loads on pallets, particularly for non-uniform loads and those sensitive to heat, while also ensuring protection from environmental factors like rain and maintaining maneuverability during transportation.
Innovation Solution
A transportable device that combines the functions of a stacker, forklift truck, and wrapper with a compact design and hinged structure, featuring support forks, a wrapping base with a forklift, and a wrapping device that allows for minimal lift to prevent friction and enables stacking, while maintaining a constant wrapping height and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a forklift truck is used to transport loads, then transportation capability is improved, but stacking capability is limited because forks cannot be raised high enough
Solution Approach 1:
The patent combines the functions of a forklift truck and a stacker into a single vehicle. The stacking mechanism is integrated with the forklift body, allowing the same vehicle to perform both transportation and stacking operations without requiring separate equipment.
Solution Approach 2:
The vehicle is designed with multi-functionality, serving as both a forklift for transporting loads and a stacker for placing loads at elevated positions. The forks can be raised to various heights through the integrated stacking mechanism, enabling versatile operation.
2Stability of the object's composition
If a stacker is used to stack loads, then stacking capability is improved, but maneuverability is reduced due to increased size and weight
Solution Approach 1:
The patent merges the stacking mechanism with a compact forklift platform, maintaining the small size and maneuverability of the forklift while adding stacking capability. The integrated design avoids the bulkiness of traditional standalone stackers.
3Strength
If straps are used to retain loads, then retention strength is improved for large items, but protection against environmental factors like rain is lost
Solution Approach 1:
The patent employs a flexible wrapping film that is stretched and shrunk around the load to provide complete environmental protection. This thin film barrier protects against rain and other environmental factors while maintaining load retention.
4Object-affected harmful factors
If stretch wrap bags are used to protect loads, then protection against environmental factors is improved, but usability is limited for non-uniform loads and heat-sensitive items
Solution Approach 1:
The patent controls the shrinking parameters of the wrap film to adjust protection levels. By modifying temperature, time, and pressure parameters during the shrinking process, the system adapts to different load types including non-uniform shapes and heat-sensitive items, providing versatile protection.
5Adaptability or versatility
If a heavy pallet carrier vehicle is used for wrapping, then wrapping capability is achieved, but center of gravity stability is compromised during lifting
Solution Approach 1:
The patent integrates the wrapping device with a lightweight forklift platform rather than using a heavy dedicated carrier vehicle. This combination achieves wrapping capability while maintaining better center of gravity stability due to the lighter base vehicle.
