Rotating Capture Head for Sheet Handling Through Cutting Slots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for handling adjacent sheet elements struggle with accessing and manipulating sheet elements separated by small cutting slots, leading to difficulties in automation, detection of cuts, and efficient handling and storage.
Innovation Solution
A device comprising a gripping clamp and a capture head with rotatable clamping means, such as air suction, adhesive, or scraping elements, that allows access and capture through small gaps, enabling precise handling and storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional top-face gripper systems are used to handle sheet elements, then the sheet elements can be captured and moved, but the fabric becomes wrinkled and delicate products are damaged
Solution Approach 1:
The invention inverts the traditional approach by accessing the sheet element from the underside through the cutting slot rather than from the top face. The capture head penetrates through the cutting slot to engage the sheet element's underside, completely avoiding contact with the top surface that causes wrinkling and damage.
Solution Approach 2:
The cutting slot itself becomes an intermediary pathway that enables access to the sheet element's underside. Instead of directly grasping the top face, the system uses the existing cutting slot as a mediator to insert the capture head and engage the sheet element from below.
2Ease of operation
If suction cups are used to capture sheet elements, then the sheet elements can be lifted and transported, but breathable or porous surfaces cannot be captured and air resistance limits transport speed
Solution Approach 1:
The invention accesses the sheet element from the underside through the cutting slot rather than from the top face, enabling engagement with porous and breathable materials that would otherwise be incompatible with suction cup systems.
Solution Approach 2:
The invention replaces the suction-based mechanical system with a direct mechanical engagement system. The capture head uses mechanical elements (such as claws or grippers) that physically engage with the sheet element's underside, eliminating dependence on suction pressure and air tightness.
3Ease of operation
If puncturing elements are used to handle sheet elements, then capture is achieved, but visual and functional defects are caused in the sheet element
Solution Approach 1:
The invention extracts the capture action from the visible top surface of the sheet element and relocates it to the underside through the cutting slot. This separation removes the harmful effect of surface contact while preserving the capture function.
Solution Approach 2:
The cutting slot serves as an intermediary that enables capture without direct contact with the sheet element's surface. The capture head passes through this intermediary pathway to engage the underside, avoiding any puncturing or marking of the visible surface.
4Ease of operation
If existing grippers are used to access sheet elements, then handling is possible in areas without adjacent sheet elements, but access through small cutting slots is prevented and degrees of freedom are limited
Solution Approach 1:
The invention segments the handling approach by separating the capture function from the traditional gripper design. The capture head is a distinct module that can be inserted through cutting slots, while the gripping clamp provides the actual capture function, enabling access in previously unreachable areas.
Solution Approach 2:
The invention adds a new dimension to the handling system by introducing a capture head that can penetrate through the cutting slot plane. This creates a third spatial dimension for access, allowing the system to reach undersides of sheet elements that were previously inaccessible from the top face.

AI summary
The device for handling adjacent sheet elements comprises a clamp (2) for gripping a sheet element (10) and a capture head (1) which is provided with clamping means (4), which separates, grips and lifts an edge of a sheet element (10). The capture head/s (1) is/are rotatable about a longitudinal axis (3).It allows the handling of sheet elements consisting of one or more layers of sheet material, allowing the clamp to slide along the surface supporting the elements to access the underside of the sheet element, thus capturing the elements on the same surface that has been used to cut them.
