Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing palletizing devices require significant installation space and are prone to collisions and wear due to the use of air hoses for creating an air cushion, which complicates the push-off of sack layers onto pallets.
Innovation Solution
A depositing table with an air feeding device and a telescopable connecting device that generates an air cushion below the sacks, allowing for a flat construction and minimizing space requirements while preventing collisions with conveying elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an air hose is used to create an air cushion for pushing off sack layers, then the push-off process is simplified and sacks do not deform, but the installation space increases and the risk of collision with conveying elements rises
Solution Approach 1:
The patent extracts the air hose from the system by replacing it with a stationary air feeding device that has integrated air outlets on the depositing surface. This eliminates the need for flexible hoses and their associated space requirements while maintaining the air cushion function for simplified push-off operation.
Solution Approach 2:
The patent introduces air outlets as an intermediary between the air source and the sack layer. These outlets directly generate the air cushion at the contact point between the depositing table and sacks, eliminating the need for intermediate flexible connections and reducing installation space.
2Ease of operation
If an air hose is used to create an air cushion, then the push-off of sack layers is facilitated, but wear and collision risks increase due to movement paths
Solution Approach 1:
The patent segments the air delivery system into multiple stationary air outlets distributed across the depositing surface. This eliminates the single-point failure risk of flexible hoses and ensures reliable air cushion generation at multiple locations simultaneously, improving operational reliability.
Solution Approach 2:
The patent replaces the mechanical flexible hose system with a stationary pneumatic system. This substitution eliminates mechanical wear and collision risks associated with flexible connections while maintaining the air cushion function that facilitates smooth push-off operation.
3Adaptability or versatility
If a monkey swing configuration is used for air hose connection, then air supply is maintained during movement, but the structural complexity and space requirements increase
Solution Approach 1:
The patent inverts the conventional approach by making the air feeding device stationary rather than mobile. The air outlets are integrated into the depositing surface itself, eliminating the need for flexible connections and complex monkey swing mechanisms while maintaining continuous air supply during table movement.
Solution Approach 2:
The depositing surface serves multiple functions: it supports the sack layer, provides the air cushion through integrated outlets, and maintains structural integrity during movement. This multi-functionality eliminates the need for separate flexible air supply mechanisms and reduces overall structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables efficient and reliable push-off of sack layers onto pallets without deformation, reducing wear and collision risks, and optimizing the assembly space.
Implementation Method 1
air is introduced for this purpose into the depositing table, which is formed to be at least partly hollow, which air escapes through openings in the bearing surface and thus forms a type of air cushion below the sack layer
