Automated Binding Tape Removal from Coils via Dynamic Rest Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for removing binding bands from coils are inefficient and require manual intervention when the bands are not positioned correctly, leading to time-consuming and inconvenient processes.
Innovation Solution
A method and installation that utilize a two-stage approach where the coil rests on different subregions of a rest to allow for automated removal of binding bands, regardless of their initial positioning, using an advancing bar for conveying and an optical detection device for precise band detection.

1Extent of automation
If the coil is positioned on tapered bottom rolls for automated binding band removal, then automated separation is achieved, but the process fails when binding bands are not positioned at expected points, requiring manual intervention
Solution Approach 1:
The system dynamically adjusts the support position along the coil's length. Instead of a fixed tapered bottom roll configuration, the support point can be moved to different positions (first position and second position) to accommodate varying binding band locations. This dynamic adaptability ensures automated removal works reliably regardless of where binding bands are positioned on the coil.
Solution Approach 2:
The system changes the positional parameter of the support along the coil's length. By moving the support from a first position to a second position spaced apart by at least the binding band width, the system adapts to different binding band configurations. This parameter change enables the automated system to handle variable binding band positions without manual intervention.
2Device complexity
If binding bands are removed using fixed tapered bottom rolls, then the process is simple, but it requires precise positioning of binding bands which is difficult to guarantee in practice
Solution Approach 1:
Rather than creating a complex multi-component system, the invention uses a simple movable support that can be positioned at different locations along the coil. This dynamic but simple mechanism provides versatility in handling different binding band positions without significantly increasing device complexity.
Solution Approach 2:
The movable support serves multiple functions: it supports the coil during transport and also provides the removal surface for binding bands regardless of their position. This universal element handles both transport and removal tasks, making the system adaptable to various binding band configurations without requiring specialized components for each scenario.
3Productivity
If manual removal is used when automated removal fails, then all binding bands can be removed, but the process becomes time-consuming and inconvenient
Solution Approach 1:
The system is designed to automatically adapt to and handle all binding band positions without requiring manual intervention. By incorporating the movable support that can be positioned at multiple locations, the system serves itself by accommodating variable binding band positions, thereby maintaining high productivity and operational convenience throughout the entire removal process.

AI summary
Coil has been produced by coiling of a strip. The coil has two end faces and a lateral surface, and also a coil eye having an eye axis. The binding bands have a binding band width. Initially, while a first subregion of the lateral surface of the coil, as seen in the direction of the eye axis, is resting on a first rest, those binding bands which, as seen in the direction of the eye axis, surround the coil completely outside the first subregion are removed. Then, while a second subregion of the coil, as seen in the direction of the eye axis, is resting on the first rest or a second rest, those binding bands which were not removed are removed. The first and the second subregion, as seen in the direction of the eye axis, are spaced apart from one another at least by the binding band width.
