Sliding Nozzle Drive Unit Mounting Against Pendular Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mounting of a drive unit in a hanging state to a sliding nozzle device using a manipulator is unstable due to swinging or pendular motion, making smooth mounting difficult.
Innovation Solution
A mounting device with a holding part and a contact part that can displace between contact and non-contact positions, equipped with a force sensor to detect and control mounting forces, ensuring stable attachment to a sliding nozzle device holder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a manipulator is used to mount a drive unit in a hanging state to a sliding nozzle device, then automation is improved, but mounting stability deteriorates due to swinging or pendular motion
Solution Approach 1:
The mounting device is divided into two independent gripping portions: a first gripping portion that holds the upper part of the drive unit and a second gripping portion that holds the lower part. This segmentation allows independent control of each gripping portion, enabling the second gripping portion to stabilize the drive unit against swinging while the first gripping portion performs the mounting operation, thus resolving the contradiction between automation and mounting stability.
2Ease of operation
If a holding mechanism is moved upwardly and downwardly to mount a drive unit, then ease of operation is improved, but adaptability to hanging state deteriorates
Solution Approach 1:
The mounting device employs dynamic gripping forces through independent control of the first and second gripping portions. The second gripping portion applies a larger gripping force to stabilize the hanging drive unit, while the first gripping portion applies a smaller gripping force sufficient for mounting. This dynamic adjustment of gripping forces enables the device to adapt to the hanging state while maintaining ease of operation.

AI summary
A mounting device capable of smoothly mounting a drive unit being in a hanging state to a sliding nozzle device, using a manipulator. The mounting device is mounted to a distal end of a manipulator to mount a drive unit whose upper end is connected to a suspending device, to a holder of a sliding nozzle device. The mounting device includes: a holding part for holding an upper portion or central portion (to-be-held plate) of the drive unit; and a contact part which is contactable with a lower portion (to-be-contacted part) of the drive unit when mounting the drive unit to the holder.
