Swivel-Mounted Holder for Reproducible Card Orientation Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for transferring flat pieces, such as plastic cards, lack efficiency and reliability in positioning them reproducibly and in a defined orientation, especially when requiring flexible positioning and orientation changes during transfer.
Innovation Solution
A device with a rotator element and a holder element that is swivel-mounted, allowing passive rotation and indirect motor-driven movement, enabling flexible orientation changes and secure positioning through magnetic or snap-lock mechanisms, and cam rollers for precise control and flipping options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If direct motor-driven rotation of the holder element is used, then positioning precision is improved, but device complexity increases
Solution Approach 1:
The rotator element acts as an intermediary between the motor element and the holder element. The motor element drives the rotator element, which in turn passively rotates the holder element via the swivel mounting connection. This intermediate mechanism transmits rotational motion while maintaining positioning precision without requiring direct motor coupling to the holder element, thus reducing device complexity.
2Reliability
If the holder element is fixed in one orientation, then positioning reliability is improved, but adaptability decreases
Solution Approach 1:
The holder element is mounted on the rotator element in a swivel-mounted manner, allowing it to rotate passively around a swivel axis. This dynamic configuration enables the holder element to adapt its orientation based on the rotation of the rotator element while maintaining reliable positioning through the controlled passive rotation mechanism. The system can achieve both fixed positioning and flexible orientation changes depending on operational requirements.

AI summary
The invention relates to a device (10) for transferring a flat piece (30), in particular a plastic card (30), from an initial position to a destination position, comprising a holder element (14) for holding the flat piece (30); and a rotator element (12), which is rotatable around a rotation axis (12a); wherein the holder element (14) is swivel-mounted to the rotator element (12), such that the holder element (14) is rotatable relative to the rotator element (12) around a swivel axis (14a); wherein, when the rotator element (12) is at a destination rotation angle, the holder element (14) can have a first or a second orientation relative to the rotator element (12); and, when the rotator element (12) is rotated from an initial rotation angle towards the destination rotation angle in a first rotation direction, the holder element (14) reaches the destination position having the second orientation relative to the rotator element (12). Furthermore, the invention relates to a method for transferring a flat piece (30), in particular a plastic card (30), from an initial position to a destination position.
