Cardboard Element Separation Device with Rotated Outlet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for separating card bodies from a stack often result in scratches, which can impair the appearance and make it difficult to detect information on the cards, leading to increased rejects during manufacturing.
Innovation Solution
A device with inlet and outlet openings in an intermediate space, where the outlet opening is rotated or displaced relative to the inlet opening, allowing the card body to be moved or twisted from the inlet to the outlet position using actuating means, reducing the risk of scratches by minimizing contact and movement along surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cards are removed from a stack using conventional methods, then the card separation function is achieved, but scratches occur on the card surface impairing appearance and information readability
Solution Approach 1:
The outlet opening is rotated and/or shifted relative to the inlet opening, creating a three-dimensional separation path. The card body is moved from the inlet position to the outlet position through rotation and/or shifting in the intermediate space, changing the separation from a two-dimensional sliding motion to a three-dimensional rotational/shifted motion that minimizes surface contact and reduces scratches
Solution Approach 2:
An intermediate space is introduced between the inlet and outlet openings to accommodate the card body during the separation process. This intermediate space allows the card to be temporarily held and repositioned without direct contact with guide surfaces that would cause scratching, acting as a protective intermediary zone
2Ease of manufacture
If cards are arranged in a stack with fixed orientation, then stacking is simplified, but separation requires complex rotation mechanisms
Solution Approach 1:
The outlet opening is designed to be rotatable and/or shiftable relative to the inlet opening, creating a dynamic separation mechanism. The actuating means enables the outlet opening to move to different positions and orientations, allowing flexible card separation without requiring complex pre-rotation of the entire card stack, thus maintaining simple stacking while enabling versatile separation

AI summary
The invention relates to a method and a device (1) for individualizing a cardboard element (2, 2a) from a cardboard element stack (3). The device (1) has an inlet opening (5), at least one actuating means, and an outlet opening (9). A first intermediate area (10) is arranged between the inlet opening (5) and the first outlet opening (9). The inlet opening (5) determines an inlet position in the first intermediate area (10), and the first outlet opening (9) determines an outlet position in the first intermediate area (10). The inlet position in the first intermediate area (10) differs from the outlet position in the first intermediate area (10), and a cardboard element (2a) arranged in the first intermediate area (10) can be moved and/or rotated by means of the actuating means out of the inlet position in the first intermediate area (10) and into the outlet position in the first intermediate area (10).
