Conventional position detecting devices face challenges with maintenance due to clogging issues and fluctuations in supply pressure, leading to mistaken detection of workpiece position, which can result in defective products and equipment stoppages.
Innovation Solution
A position detecting device with an attaching/detaching mechanism that allows for easy removal and cleaning of the internal nozzle, along with a pressure fluid management system that includes gauge pressure sensors to accurately detect back pressure without being influenced by foreign matter, facilitating precise detection and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the internal nozzle is made integral with the device main body, then the structural strength is improved, but the ease of repair deteriorates because the entire device must be dismantled for cleaning
Solution Approach 1:
The internal nozzle is divided into a separate component that can be detached from the device main body. The attaching/detaching mechanism allows the internal nozzle to be removed independently for cleaning without dismantling the entire device, resolving the contradiction between structural strength and ease of repair.
2Device complexity
If the position detecting device is made compact, then the device complexity is reduced, but the ease of operation deteriorates due to limited access for maintenance
Solution Approach 1:
The internal nozzle is designed as a detachable component with an attaching/detaching mechanism that enables easy access for maintenance. This segmentation allows the compact device structure to be maintained while providing convenient access to the internal nozzle for cleaning and maintenance operations.
3Measurement precision
If foreign matter clogs the internal nozzle, then the measurement precision deteriorates due to mistaken detection, but the device complexity increases with additional cleaning requirements
Solution Approach 1:
The detachable internal nozzle design allows for easy removal and cleaning to prevent foreign matter clogging. This segmentation enables rapid maintenance without increasing overall device complexity, ensuring detection accuracy is maintained by allowing quick clearing of clogs.
Solution Approach 2:
The attaching/detaching mechanism enables operators to easily remove and clean the internal nozzle themselves without requiring specialized tools or complex procedures. This self-service capability maintains measurement precision by enabling quick clearing of clogs while avoiding the need for complex maintenance systems.

Implementation Method 1
a pressure sensor 172 connected to a detection port 158 side of the internal nozzle 170. The pressure sensor 172 detects a pressure (back pressure) of the pressure fluid during the time that the pressure fluid is ejected toward the detection surface 168
Data Source
AI summary
A position detecting device is equipped with a device main body into which a pressure fluid supplied from a pressure fluid supply source is introduced, and an attaching/detaching mechanism that enables attachment and detachment with respect to the device main body. The attaching/detaching mechanism includes an internal nozzle that delivers, toward the side of a detection nozzle, the pressure fluid supplied to the device main body, and a detection port that supplies, to the detection nozzle, the pressure fluid delivered from the internal nozzle.
