Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating individual intermediate layers from a stack face challenges due to electrostatic adhesion and mechanical interlocking, leading to delays and instability during high-speed palletizing processes.
Innovation Solution
A method utilizing a suction and/or gripping device that pneumatically grips the top intermediate layer, lifts its outer edge while maintaining surface contact, and then moves it away from the stack, employing an offset movement and rotation to reduce adhesion, allowing for reliable and efficient separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If intermediate layers are stacked closely together to save space and increase throughput, then productivity is improved, but electrostatic adhesion and mechanical interlocking cause difficulty in separating individual layers
Solution Approach 1:
The suction and gripping device performs preliminary actions by first gripping the intermediate layer, then lifting an outer edge while maintaining surface contact with the stack, and finally moving in the opposite direction of the target location with an offset. This sequence of preliminary actions reduces adhesion before complete separation, enabling reliable detachment even when layers are closely stacked for high productivity
Solution Approach 2:
The suction and gripping device acts as an intermediary between the intermediate layer and the stack. It maintains surface contact during the separation process, using controlled offset movement to mediate the detachment while minimizing adhesion forces. This intermediary approach allows layers to be separated reliably without requiring excessive force or complex mechanisms
2Productivity
If high-speed separation is used to increase throughput, then productivity is improved, but adhesion forces cause delays and process stoppages
Solution Approach 1:
The suction and gripping device maintains continuous useful action throughout the separation process. By keeping surface contact during the offset movement and only releasing grip after complete separation, it eliminates interruptions and process stoppages. This continuous action ensures high-speed operation without time losses due to adhesion-related failures
Solution Approach 2:
The method rushes through the critical separation phase by quickly performing the offset movement in the opposite direction of the target location. This rapid action skips through the adhesion zone before electrostatic and mechanical forces can cause delays, enabling high-speed separation that maintains productivity without process interruptions
3Ease of manufacture
If simple gripping is used to minimize device complexity, then ease of manufacture is improved, but adhesion causes unreliable separation
Solution Approach 1:
The suction and gripping device employs dynamic control rather than static gripping. It dynamically adjusts the gripping force and movement trajectory, performing offset movements in the opposite direction of the target location while maintaining surface contact. This dynamic approach enables reliable separation using a relatively simple device structure without requiring complex mechanical systems

AI summary
The invention discloses a method and an apparatus for separating individual intermediate layers (7). Within the context of the method, an intermediate layer (7) which is arranged at the top of a stack (10) of intermediate layers is gripped by at least one suction and/or gripping device (9). Furthermore, an outer edge (4) of the gripped intermediate layer (7) is raised by the at least one suction and/or gripping device (9), the intermediate layer (7) continuing to remain in surface contact with the stack (10) of intermediate layers. In addition, the raised intermediate layer (7) is drawn off from the stack (10) of intermediate layers by virtue of the at least one suction and/or gripping device (9) moving in the direction of a destination (ZO), the intermediate layer (7) losing its surface contact with the stack (10) of intermediate layers. After the intermediate layer (7) has been gripped, and prior to the intermediate layer (7) being drawn off, the at least one suction and/or gripping device (9) undergoes offsetting (18) by a certain distance and, for this purpose, moves in the direction counter to the destination (ZO).
