Material Feeding Apparatus Vibration Isolation Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional material feeding apparatuses face challenges in maintaining high-speed and high-accuracy material feeding to press apparatuses due to vibrations caused by impulse forces, which can lead to equipment breakage and accuracy degradation, especially when using vibration-absorbing members that are not effectively positioned to mitigate these issues.
Innovation Solution
A double-structured housing with vibration-absorbing members like vibration-proof rubber that dampen impulse-induced vibrations and a vibration-restricting member that limits the transmission of these vibrations to the inner housing, allowing only vertical movement, thereby stabilizing the material feeding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a vibration absorbing member is provided between the press apparatus and material feeding apparatus, then breakage from impulse force is prevented, but feeding accuracy deteriorates due to excessive elasticity
Solution Approach 1:
The housing is divided into an outer housing connected to the press apparatus and an inner housing accommodating the material feeding mechanism. This segmentation allows the outer housing to absorb vibrations while the inner housing maintains stability for precise feeding operations.
Solution Approach 2:
A vibration absorbing member is positioned between the outer housing and inner housing as an intermediary element. This mediator absorbs impulse forces from the press apparatus while isolating the inner housing and material feeding mechanism from excessive vibrations, thereby maintaining feeding accuracy.
2Device complexity
If the servomotor and press apparatus are clamped directly together, then structural simplicity is achieved, but vibrations cause degradation in feeding accuracy and potential breakage
Solution Approach 1:
The mounting structure is segmented into an outer housing for direct clamping to the press apparatus and an inner housing for accommodating sensitive components. This segmentation allows direct mounting simplicity while protecting the servomotor and feeding mechanism from harmful vibrations through the double-housing configuration.
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
This configuration effectively prevents breakage and maintains high-speed, high-accuracy material feeding by isolating the inner housing from harmful vibrations, ensuring the material is fed stably and accurately, even under impulse forces from the press apparatus.
Implementation Method 1
vibrations caused by an impulse force acting on the outer housing are damped by the vibration absorbing member (or a cushioning member) such as a vibration proof rubber, etc. and transmitted to the inner housing
Implementation Method 2
the vibration restricting member restricts the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member from the outer housing, in one direction

AI summary
A material feeding apparatus has a vibration absorbing construction, in which an impulse and vibrations from a press apparatus (4), etc. are hard to transmit to a material feeding equipment (5, 6), etc., and includes an inner housing (9) that accommodates therein the material feeding equipment, and an outer housing (11) connected to the inner housing through a vibration absorbing member (10a, 10b, 10c, 10d). A vibration restricting member (15, 16) is provided between the housings to restrict the degree of freedom of vibrations, which are transmitted to the inner housing through the vibration absorbing member when an impulse force acts on the outer housing, only in a vertical direction. The vibration restricting member includes an upper plate member (15), upper and lower surfaces of which are interposed between a top wall of the outer housing and a top wall of the inner housing, and a lower plate member (16), upper and lower surfaces of which are interposed between a bottom wall of the outer housing and a bottom wall of the inner housing.
