Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing destacking systems for objects with flanges, such as trays and containers, face challenges in high-speed production due to mechanical construction limitations, lack of adjustability, and inability to compensate for errors, leading to production stops and inefficiencies.
Innovation Solution
A destacking system employing rotational motion converted into linear displacement through threaded engagement, with an inclined surface to separate the bottom object from the stack while keeping others still, and a reciprocal rotational motion controlled by an actuator for precise angular extension, ensuring reliable and efficient separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If trays are stacked tightly together to optimize logistics and handling, then storage efficiency is improved, but separation between trays during production is not ensured leading to production bottlenecks
Solution Approach 1:
The destacker unit performs preliminary separation action by engaging the flange of the tray to be separated before the main separation occurs. The steering profile预先 positions the tray for clean separation, preventing bottlenecks while maintaining tight stacking during storage and transport.
Solution Approach 2:
The destacker divides the stack into individual trays through sequential engagement and separation. The steering profile segments the stacking force from the separation force, allowing tight stacking to be maintained during storage while enabling reliable individual separation during production.
2Reliability
If a mechanical construction with supporting planes is used to separate trays, then tray separation is achieved, but the system requires careful assembly and cannot compensate for errors accumulating during high-speed production
Solution Approach 1:
The patent replaces complex mechanical supporting planes with a steering profile having a specific geometric shape. This profile guides the tray through engagement and separation using its inherent geometry rather than requiring multiple carefully assembled mechanical components, reducing assembly complexity while maintaining separation reliability.
Solution Approach 2:
The steering profile's geometric parameters are designed to compensate for errors that may accumulate during high-speed production. The specific shape and dimensions of the profile allow it to adapt to variations in tray positioning, maintaining reliable separation without requiring precise assembly tolerances.
3Reliability
If destacking systems are designed for limited types of flange geometry, then specific tray types can be processed, but adaptability to different tray types is reduced
Solution Approach 1:
The steering profile is designed with universal geometric characteristics that can engage with different flange geometries. Its shape allows it to interface with various tray types while maintaining the same engagement and separation mechanism, providing adaptability across different tray designs without compromising destacking reliability.
4Productivity
If high-speed production is implemented, then productivity increases, but error accumulation from previous trays may result in production stops
Solution Approach 1:
The steering profile provides continuous geometric feedback during the destacking process. Its shape ensures that each tray's position is corrected relative to the previous tray, preventing error accumulation even at high production speeds and maintaining production continuity.

AI summary
A destacker unit for a destacking system is for destacking objects with a flange that are stacked together, such as a stack of trays, containers, cups or other objects. A destacking system includes at least one destacker unit for repeated destacking of one tray at a time in a predetermined direction. A stack of objects each having a flange extending outwards along its perimeter may be destacked in a predetermined direction by rotational motion of the destacker unit. The destacker unit may include a wheel unit, having a threaded rotation axis, including: a lower surface for carrying the stacked objects, and an inclined member located above the lower surface and having an inclined upper surface and a bottom surface. The distance between the upper and bottom surface increases around at least a part of the periphery of the wheel unit. The thread orientation corresponds to the inclination of the surface.
