Conveyor-Guided Cut-Piece Feeding for Precise Forming Drum Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The quality of tyres produced on forming drums is compromised by deformation and incorrect deposition of continuous elongated elements during transport and cutting, particularly for asymmetrical elements lacking reinforcing structures.
Innovation Solution
A motorized conveyor system is used to support and accompany continuous elongated elements from dispensing to cutting and deposition on the forming drum, maintaining geometric and mechanical features by blocking and guiding the elements with manipulation elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If continuous elongated elements are transported and cut without support structures, then the device complexity is reduced, but the elements undergo deformation and incorrect deposition compromising tyre quality
Solution Approach 1:
A conveyor belt acts as an intermediary support structure between the cutting unit and the forming drum. The belt receives cut pieces from the cutting unit, maintains their correct orientation through guided movement, and deposits them precisely on the forming drum, preventing deformation during transport.
Solution Approach 2:
The conveyor system is positioned and configured in advance to receive cut pieces at the correct orientation and position. The belt is pre-aligned with the cutting unit and forming drum, ensuring that pieces are captured and transported in their correct orientation before any deformation can occur.
2Adaptability or versatility
If asymmetrical elongated elements lacking reinforcing structures are handled, then the adaptability of the system is improved, but the elements are more susceptible to deformation during transport
Solution Approach 1:
The conveyor belt provides a flexible yet supportive surface that adapts to the shape of asymmetrical elongated elements. The belt's surface characteristics and movement pattern are designed to accommodate various geometries while maintaining sufficient support to prevent deformation of elements lacking rigid reinforcing structures.

AI summary
A method and a device for feeding pieces of a continuous elongated element towards a forming drum, wherein the device comprises: a motorized conveyor (7) configured to transport a continuous elongated element (2); a cutting unit (14) placed immediately downstream of the motorized conveyor (7) and configured to cut into pieces (4) the continuous elongated element (2) coming from the motorized conveyor (7); a manipulation unit (20) comprising a manipulation element (21). The manipulation element (21) is configured to block the continuous elongated element (2) in the cutting unit (14) while the cutting unit (14) cuts a piece (4) from the continuous elongated element (2) and to transport a head end (22) or a tail end of the piece (23) towards a deposition surface located further downstream.
