Rivet Control Shaft Pivoting Mechanism for Supply Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rivet supply systems face challenges in achieving precise and efficient movement control of rivet elements due to complex structural arrangements, often requiring expensive and fault-prone linear guides, which complicates the design and increases the need for separate control actuators for each rivet control unit.
Innovation Solution
A rivet control system utilizing a control shaft that penetrates the rivet channel, allowing for pivoting to control the passage of rivet elements and fluid, eliminating the need for linear guides and enabling a single control shaft to serve multiple rivet control units, thereby simplifying the design and enhancing motion control options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If locking slides are used for rivet control, then movement control of rivet elements is achieved, but device complexity increases due to structurally complex overall arrangement
Solution Approach 1:
The control shaft integrates multiple control functions into a single unified component that penetrates the rivet channel and controls multiple rivet control units simultaneously, merging what would otherwise require separate locking slides and actuators into one compact structure
Solution Approach 2:
The control shaft serves multiple rivet control units with a single component, providing universal control capability across different positions and functions, eliminating the need for dedicated control mechanisms for each individual unit
2Measurement precision
If separate control actuators are provided for each rivet control unit, then precise control is achieved, but device complexity and cost increase
Solution Approach 1:
Multiple control functions that would require separate actuators are merged into a single control shaft, reducing the total number of actuators while maintaining control precision through the shaft's ability to selectively position and control different rivet control units
3Manufacturing precision
If linear guides are used for control shaft guidance, then precise pivoting is achieved, but device complexity and cost increase
Solution Approach 1:
The complex linear guide system is extracted and removed from the design, replacing it with a simplified pivoting mechanism for the control shaft that achieves the necessary precision without requiring expensive and fault-prone linear guides

Function Achieved in This Case
This solution allows for effective and structurally simple movement control of rivet elements, reducing design complexity and eliminating the need for separate actuators, resulting in a more compact and efficient rivet supply device.
Implementation Method 1
a control shaft (5) which penetrates at least part of a rivet channel (3) in such a way that the passage of rivet elements (1) and/or fluid through the control area (6) can be controlled by pivoting the control shaft (5)
Implementation Method 2
the control shaft (5) in a blocking position essentially blocks the passage of rivet elements (1) and/or fluid between the input section (3a) and the output section (3b)

AI summary
The arrangement has a rivet conveying unit (10) that conveys the rivet elements (1) from an input section (3a) of channel (3) to an output section (3b) of channel. A control shaft (5) passes through a control region (6) provided between input portion and output section of channel so as to control the passage of the rivet elements. An independent claim is included for rivet producing device.
