Skew Roller Axis Cleaning Device for Machining Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning devices for machining rollers, such as those used in vehicle construction, are inefficient due to the need for additional drive devices to achieve effective cleaning, which increases complexity and maintenance efforts.
Innovation Solution
A cleaning procedure and device that utilize a single driven brush roller, where the machining roller's axis is aligned or angled relative to the brush roller's axis, allowing the brush roller's bristles to effectively remove contaminants while inducing rotation in the machining roller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the processing roller is moved towards a rotating brush roller until their outer circumferences rest against each other with parallel roller axes, then the brush roller can remove contaminants from the processing roller, but the processing roller rotates at the same speed as the brush roller resulting in an inefficient cleaning process
Solution Approach 1:
The invention applies asymmetry by aligning the roller axes of the processing roller and brush roller skew to each other instead of parallel. This skew alignment creates a speed difference between the two rollers during contact, generating relative motion that dramatically improves cleaning efficiency without requiring additional drive devices on the processing roller.
2Productivity
If an additional drive device is provided to rotate the processing roller in the opposite direction or at a different speed, then cleaning performance is improved, but the device complexity increases
Solution Approach 1:
The invention employs self-service by utilizing the inherent rotation of the processing roller during its normal operation on the processing tool. The skew alignment between roller axes allows the processing roller's own rotation to create the necessary relative motion for effective cleaning, eliminating the need for separate drive mechanisms and reducing device complexity.
3Productivity
If two brush rollers are used to form a roller nip for cleaning the processing roller, then cleaning efficiency is improved, but the number of moving parts increases leading to higher maintenance effort
Solution Approach 1:
The invention extracts the essential cleaning function from a dual-brush-roller system and implements it with a single brush roller. By using skew alignment between the processing roller and single brush roller axes, the patent achieves effective cleaning with fewer moving parts, thereby reducing maintenance effort while maintaining cleaning efficiency.
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 approach enhances the efficiency of the cleaning process by ensuring complete coverage and removal of contaminants from the machining roller's surface without the need for additional drive devices, thereby reducing maintenance and improving cleaning performance.
Implementation Method 1
the bristles of the brush roller rest on the surface of the processing side of the processing roller
Implementation Method 2
If the brush roller resting against the folding roller is driven by the drive device, contaminants can be removed from the folding roller

AI summary
The invention relates to a method for cleaning a rotatably mounted machining roller of a machining tool with a cleaning device, wherein the machining roller is brought towards a brush roller set in rotation by means of a drive device of the cleaning device until a section of the outer circumference of the machining roller abuts a section of the outer circumference of the brush roller. The machining roller (2) is brought towards the brush roller (6) in such a way that, when the outer circumference of the machining roller (2) abuts the outer circumference of the brush roller (6), a roller axis (4) of the machining roller (2) and a roller axis (5) of the brush roller (6) are skew to each other. The invention further relates to a cleaning device for carrying out the method.
