Tire Member-Forming Apparatus With Tilting Guide Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tire member-forming apparatuses have a large footprint and limited work area due to the need for a large turning space, making it difficult to install them adjacent to other apparatuses and compromising worker safety and efficiency when applying rubber strips to non-straight cylindrical wound bodies.
Innovation Solution
A tire member-forming apparatus with a transport conveyor system featuring a transport belt guided by guide rollers that can tilt around a center line, allowing the foremost guide roller to adjust to the wound body's profile without requiring a large turning space, and a press conveyor with a twistable press surface to ensure accurate application of rubber strips without wrinkles or distortion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the transport conveyor entirely turns around the vertical axis to accommodate non-straight cylindrical profiles, then the rubber strip can be stuck with high accuracy, but the apparatus requires a large turning space that increases footprint and limits work area
Solution Approach 1:
The transport conveyor is divided into multiple independent guide rollers (front guide rollers and back guide rollers) that can tilt individually around the center line of the transport surface. This segmentation allows each roller to adjust to the wound body profile independently, eliminating the need for the entire conveyor to turn around a large vertical axis, thereby reducing the apparatus footprint while maintaining sticking accuracy.
Solution Approach 2:
The guide rollers are designed with dynamic tilting capability around the center line of the transport surface, allowing them to adjust their orientation in real-time to match the non-straight cylindrical profile of the wound body. This dynamic adjustment enables accurate rubber strip application without requiring a large fixed turning space, resolving the contradiction between precision and footprint.
2Manufacturing precision
If the transport conveyor entirely turns around the vertical axis, then the rubber strip can be stuck with high accuracy, but the work area for workers is significantly limited due to collision risk
Solution Approach 1:
By segmenting the conveyor into independent tilting guide rollers rather than a single large turning mechanism, the patent creates a more compact structure that reduces the radius of operation. This allows workers to access the work area more freely without the risk of collision with a large rotating conveyor, while still achieving high sticking accuracy through the localized tilting capability of each roller.
Solution Approach 2:
Instead of turning the entire conveyor around a vertical axis (rotational movement in one dimension), the guide rollers tilt around the center line of the transport surface (angular adjustment in another dimension). This dimensional change creates a more compact configuration that preserves work area accessibility while maintaining the ability to accommodate non-straight cylindrical profiles for accurate rubber strip application.
3Area of stationary object
If the guide rollers are held capable of tilting around the center line of the transport surface, then the apparatus footprint is reduced, but the mechanism becomes more complex
Solution Approach 1:
The patent divides the conveyor system into multiple independent guide rollers that each perform a simple tilting motion around the center line. This segmentation transforms a complex large-scale rotation into multiple simple, identical, and standardized tilting mechanisms. Each roller's mechanism is relatively simple and can be manufactured and maintained easily, offsetting the increased number of components through modularity and standardization.

AI summary
The present invention glues a rubber strip on the surface of a non-right circular cylindrical winding body with good precision. The present invention reduces the space occupied by the apparatus. The tire member-forming apparatus is provided with a transport conveyor with a conveyor belt that is guided by guide rollers so that the conveyor belt is able to circle. The conveyor surface of the conveyor belt is provided with a conveyor surface width center line that extends in a straight line over the entire length thereof. The guide rollers are grouped into guide rollers on the front side of the conveyor direction and guide rollers on the back side of the conveyor direction. The front guide rollers are held so as to be capable of tilting around the conveyor surface width center line. As a result, on the conveyor surface, a twistable twisting conveyor surface section is formed between a front conveyor surface section, which is supported by the front guide rollers, and a back conveyor surface section, which is supported by the back guide rollers.
