Linear Transport Object Transfer Between Drive Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing linear transport systems restrict the spatial arrangement of objects, rotors, and drive units, allowing objects to be arranged only above or below the long stator linear motors, limiting flexibility in object transfer.
Innovation Solution
A method for transferring an object from a first rotor to a second rotor in a linear transport system, where the transfer occurs in a transfer region between two drive units, allowing for synchronized movement of the rotors and formation/release of force-fit and/or form-fit connections between the object and the rotors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If objects are permanently connected to rotors and transferred together between long stator linear motors, then object transfer is achieved, but the spatial arrangement of objects is restricted to only above or below the drive units
Solution Approach 1:
The object transfer process is segmented into two independent connections: a first force-fit/connection between the object and first rotor, and a second force-fit/connection between the object and second rotor. This segmentation allows the object to be selectively connected to different rotors without requiring permanent attachment, thereby enabling flexible spatial arrangement while maintaining transfer capability.
Solution Approach 2:
The connection between the object and rotors is made dynamic rather than static. The first and second force-fit/form-fit connections can be selectively formed and released based on operational requirements. This dynamic connection system allows objects to be arranged in various spatial configurations (not limited to above or below drive units) while maintaining controlled transfer between rotors.
2Adaptability or versatility
If rotors are arranged with two different sides on one drive unit, then object transfer between drive units is enabled, but object arrangement options are limited
Solution Approach 1:
The object itself serves as an intermediary element between the first rotor and second rotor. Through the first and second force-fit/form-fit connections, the object mediates the transfer process, allowing flexible spatial arrangement of rotors and drive units without requiring complex coordinated control of multiple rotors on each drive unit.
Solution Approach 2:
The first force-fit/form-fit connection is established in advance before transfer occurs. This preliminary connection secures the object to the first rotor, enabling subsequent transfer operations to proceed smoothly. The preliminary action simplifies operation by pre-establishing the object-rotor relationship before the actual transfer between drive units.

AI summary
A method for transferring an object from a first rotor to a second rotor in a linear transport system is provided in a transfer region between a first drive unit and a second drive unit. The rotors move along the drive units due to a magnetic field generated by respective coil units, and the object is initially attached to the first rotor with the aid of a first connection. The method includes synchronizing movements of the first and second rotor so that the first and second rotor move with coordinated trajectories in the transfer region, forming a second connection between the object and the second rotor in the transfer region, and releasing the first connection. The first connection is created with the aid of a first retaining element, and the second connection is created with the aid of a second retaining element.
