Ring-Closed Conveyor for Ribbon Roll Trimming Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current devices for eliminating trimmings of rolls or logs of ribbon-like material associated with shearing machines are complex, costly, and require intricate synchronization, leading to obstacles in the movement of rolls and interference with conveyors, making them inefficient and difficult to use.
Innovation Solution
A device featuring a series of presses and a ring-closed conveyor system with interpenetrating chains and flaps that create a movable opening for trimmings to fall into, allowing synchronized movement without complex synchronization, and a collection system for efficient trimming removal.

Engineering Contradiction Analysis
1Reliability
If a ring-closed conveyor with pushers, blocks, and trippings is used to eliminate trimmings, then trimmings can be eliminated, but the device becomes complex and costly with intricate synchronization requirements
Solution Approach 1:
The patent extracts and eliminates the complex synchronization mechanism (pushers, blocks, trippings) from the conveyor system. Instead of using these interconnected components that require precise timing, the invention uses a simple ring-closed conveyor that continuously moves rolls along a fixed path, allowing trimmings to be eliminated without complex active control mechanisms.
Solution Approach 2:
The patent merges the trimming elimination function directly into the continuous conveyor path. Rather than having separate pusher mechanisms and timing systems, the conveyor itself provides the continuous movement needed for both transporting rolls and eliminating trimmings through a unified, simple structure.
2Ease of operation
If complex synchronization mechanisms are used to coordinate pushers and conveyors, then rolls can be moved, but the device requires intricate synchronization and accessory parts
Solution Approach 1:
The ring-closed conveyor is designed to be self-sufficient, continuously moving rolls along its fixed path without requiring external synchronization signals or coordinated activation of multiple mechanisms. The system serves itself through its inherent continuous motion, eliminating the need for complex control systems.
3Ease of manufacture
If a simple conveyor structure is used, then the device is easy to construct, but it may create obstacles in roll movement and interfere with conveyor operation
Solution Approach 1:
The conveyor path is segmented into distinct zones: the feeding plane where rolls enter, the transport section where rolls move continuously, and the trimming elimination zone where trimmings are removed. This segmentation allows each section to be optimized for its specific function while maintaining overall simplicity.
Solution Approach 2:
The ring-closed conveyor provides dynamic continuous motion, adapting to the flow of rolls and trimmings automatically. The continuous loop structure allows the system to maintain steady productivity without mechanical interference, as the conveyor naturally accommodates the varying loads of rolls and trimmings along its path.

AI summary
A device for the elimination of trimmings of rolls or logs of ribbon-like material associated downstream with a shearing machine of at least one roll or log (11), fed by a feeding plane (13) of rolls (10) and head and/or tail rolls (24), consecutively. The device comprises a conveyor group (14) for carrying the rolls (10) and eliminating the head and/or tail rolls (24,24′), wherein the feeding plane (13) comprises rests (15) and the conveyor group (14) comprises flaps (21), both shaped, facing each other and spaced between each other to define central longitudinal openings (16 and 22) for the passage of pushers (17) which allow at least one roll or log (11) to advance; the conveyor group (14) having chains (20) on which flaps (21) are positioned, and having a length of chains (20) without flaps (21) that define a movable opening (23) between adjacent chains.
