Roll Handling System Positioning Means Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roll handling systems for winders are limited in processing multiple rolls simultaneously, leading to reduced productivity and are structurally complex, making them inefficient for handling multiple cores or rolls.
Innovation Solution
A roll handling system with a feed unit and a receiving unit, equipped with a pick-up unit and positioning means, allows for the simultaneous processing and precise alignment of multiple sleeves with material webs, enabling efficient transfer and positioning of rolls within the winder, including the use of shell elements and a guide element for accurate placement and movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a roll handling system processes only one core or one roll at a time, then the system structure can be simpler, but the productivity is significantly reduced
Solution Approach 1:
The system divides the roll handling process into separate functional units: a feed unit for loading multiple cores, a receiving unit for processing rolls, and a transfer station for movement. This segmentation allows parallel processing of multiple rolls while keeping each unit's structure manageable, resolving the contradiction between productivity and complexity.
Solution Approach 2:
The patent combines multiple cores and rolls into a single integrated handling system that processes them simultaneously. The receiving unit accommodates multiple cores arranged side by side, and the feed unit supplies material webs to all cores concurrently, achieving high productivity without proportionally increasing overall system complexity.
2Productivity
If the pick-up unit is fixed in position, then the structure is simpler, but the ability to transfer multiple rolls efficiently is reduced
Solution Approach 1:
The pick-up unit is designed to be movable rather than fixed, allowing it to dynamically position itself between the feed unit and transfer station. This dynamic capability enables efficient transfer of multiple rolls while the movement mechanism remains relatively simple, using basic linear actuation along a defined path.
3Manufacturing precision
If positioning means are not provided on the receiving unit, then the structure is simpler, but the alignment precision of cores during transfer is insufficient
Solution Approach 1:
Positioning means are provided locally at specific locations on the receiving unit where cores need to be aligned during transfer. These positioning elements are strategically placed to ensure correct positioning only at critical transfer points, rather than throughout the entire system, maintaining simplicity while achieving necessary precision.

AI summary
The invention relates to a roll handling system for a winder (50), in which a material web (2) can be applied to cores (1) such that a plurality of rolls (3) consisting of cores (1) wound with a material web (2) are produced. Said system comprises a supply unit (10) for transferring a plurality of cores (1) to a receiving unit (20), said receiving unit (20) being movably arranged between the supply unit (10) and a transfer station (60), and by means of which receiving unit cores (1) can be conveyed to the winder (50) and rolls (3) can be transferred from the winder (50) to the transfer station (60). According to the invention, the receiving unit (20) comprises a first contact surface (23) having positioning means (24), for aligning the cores (1) on the receiving unit (20) by means of a positioning device (80) arranged between the supply unit (10) and the transfer station (60).
