Suction Device Tilting Member for Inclined Workpiece Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Suction devices face challenges in maintaining contact with workpieces that are inclined or have fluid contents, leading to positional deviations and potential dropping during transport due to inertial forces.
Innovation Solution
A suction device with a tilting member inside the bellows that can adjust to changes in the workpiece's center of gravity, ensuring the suction pad remains in close contact and effectively applies negative pressure, preventing slippage and positional deviations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed suction pad is used, then the structure is simple, but the suction pad cannot maintain close contact with inclined workpieces, resulting in suction defects
Solution Approach 1:
The suction device incorporates a tilting member that allows the suction pad to dynamically adjust its angle relative to the workpiece surface. This dynamic adjustment capability enables the suction pad to maintain close contact with inclined workpieces, resolving the contradiction between operational effectiveness and structural simplicity.
2Adaptability or versatility
If the suction pad is made rigid to maintain structural stability, then the structure is stable, but the suction pad cannot adapt to workpiece inclination and center of gravity changes, causing positional deviation
Solution Approach 1:
The tilting member provides controlled adaptability by allowing the suction pad to tilt in response to workpiece inclination and center of gravity changes, while the bellows provides elastic compensation that maintains structural stability during dynamic adjustment.
Solution Approach 2:
The bellows acts as a flexible element that can elastically deform to accommodate tilting movements of the suction pad, providing both adaptability to workpiece variation and maintaining structural integrity through its elastic properties.
3Productivity
If the suction device operates at high speed to improve productivity, then productivity increases, but inertial forces cause workpiece slippage and dropping
Solution Approach 1:
The dynamic tilting capability allows the suction pad to continuously adapt to workpiece position changes caused by inertial forces during high-speed transport, maintaining effective suction contact and preventing slippage or dropping, thus enabling high productivity with maintained reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The tilting member allows the suction device to maintain contact and attract workpieces reliably, preventing positional deviations and dropping, even under inertial forces, ensuring stable transport.
Implementation Method 1
a bellows (14) connected to a lower end of the adapter (12)... a suction device which uses an elastic bellows
Implementation Method 2
the contents undergo movement due to the inertial force acting with respect to the workpiece... in the case that the inertial force acting on the workpiece is large relative to the suction force

AI summary
A suction device includes an adapter having in the interior thereof a supply passage to which a negative pressure fluid is supplied, a bellows connected to a distal end of the adapter, and a pad member disposed at a distal end of the bellows and to which a workpiece is attracted under suction. In addition, the suction device attracts the workpiece under suction by a negative pressure fluid which is supplied to the pad member through the supply passage and the bellows. An attachment which is capable of being tilted with respect to the axis of the bellows is provided in the interior of the bellows. In the attachment, a main body portion thereof is disposed in facing relation to a suction surface of a skirt, and a shaft portion is inserted into the supply passage at a time that the workpiece is attracted under suction.
