Tyre Building Drum Turn-Up Arm Positioning Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tyre building drums with turn-up mechanisms often produce tyres of inferior quality due to incomplete movement of arms into the starting position, leading to incorrect positioning of tyre components and unsafe process steps.
Innovation Solution
Incorporation of a detection device using a compressed air source and air channel with a flow and/or pressure meter to ensure that movable parts, such as arms, are correctly positioned, preventing further process steps if not in the desired position and activating alarms or stopping the operation if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a simple turn-up mechanism with hinging arms is used, then the device complexity is reduced, but the reliability of arm positioning deteriorates
Solution Approach 1:
The patent implements a detection device that monitors the position of the arm support and provides feedback to the control system. When the arm support is not in the desired starting position, the detection device generates a signal that prevents the next process step from being executed, ensuring reliable positioning without increasing mechanical complexity
Solution Approach 2:
The patent replaces complex mechanical positioning mechanisms with a detection-based control system. Instead of relying solely on mechanical precision, the system uses sensors to detect arm support position and electronically controls process progression, thereby maintaining simplicity while improving reliability
2Productivity
If the arms are not fully moved into the starting position, then the productivity is maintained, but the manufacturing precision deteriorates
Solution Approach 1:
The detection device continuously monitors whether the arm support has reached the desired starting position. If the positioning is incomplete, the system receives feedback and prevents the next process step, ensuring manufacturing precision is maintained without reducing productivity through unnecessary delays
Solution Approach 2:
The system performs preliminary detection of arm support positioning before allowing the next process step to proceed. This preliminary check ensures that positioning accuracy requirements are met before continuing with tyre building operations

Implementation Method 1
a detection device for detecting whether at least one movable part of the tyre building drum is in a wanted position, wherein the detection device comprises a compressed air source and an air channel connected or connectable with the compressed air source, wherein the air channel comprises an opening, and wherein the movable part, at least in or near the wanted position, is coupled to the opening for adjusting or changing a flow and/or a pressure in the air channel
Implementation Method 2
wherein the detection device furthermore comprises a flow and/or pressure meter for measuring the flow or the pressure, respectively, in the air channel

AI summary
Tire building drum having a turn-up mechanism for use in building an unvulcanized tire using rubber tire components, having two sets of turn-up arms (14), wherein each set of arms is connected to an axially shiftable arm support (17). The tire building drum is provided with means on the one hand for shifting the arm supports in a first direction to move the sets of turn-up arms axially towards each other, wherein the arras are tiltable in radial planes from a starting position to a tilting position, and on the other hand for in a second direction, opposite the first direction, shifting the arm supports to move the arms axially apart from the tilting position into the starting position. The tire building drum is provided with a pneumatic detection device (20) (23) for detecting whether at least one of the moving parts, such as the arms or the clamping device, are in the starting position, and for giving a detection signal indicating whether or not the arms are in the starting position.
