Solution Overview

Problem

The handling of long finish belts in superfinishing processes is error-prone due to their length and the difficulty in managing heavy collection rolls, leading to increased risks of detachment and inefficient disposal.

Innovation Solution

A motor-driven separating device with cutting discs, allowing for controlled and frequent cutting of short finish belt sections, which can be collected and disposed of easily without interrupting the machining process, using a separating device with grooving and circular knife discs that rotate in opposite directions for precise cutting and frictional engagement elements for torque transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If long finishing belts are used to reduce the frequency of changing belts, then the number of belt changes decreases, but the handling becomes error-prone and the risk of detachment increases

Engineering Contradiction:
Improvefrequency of belt changesVSAvoidhandling reliability
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The invention divides the long finishing belt into manageable sections by introducing a separating device that automatically cuts the belt at predetermined intervals. This segmentation allows the system to use long belts for extended operation while maintaining reliable handling through automated section separation and collection.

Inventive Principle:
Principle #1Segmentation

2Productivity

If long finishing belts are wound onto collection rolls for disposal, then complete belts can be collected, but the rolls become heavy and difficult to handle

Engineering Contradiction:
Improvecollection efficiencyVSAvoiddisposal ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The separating device automatically segments the finishing belt into predetermined sections during the collection process. This segmentation results in smaller, lighter sections that are much easier to handle and dispose of, eliminating the difficulty of managing heavy fully-wound collection rolls.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system performs self-service by automatically cutting and collecting belt sections without requiring manual intervention for the entire belt length. The automated separation and collection process reduces the need for heavy-duty handling equipment and manual labor.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If frequent cutting of short finishing belt sections is performed, then disposal becomes easier, but the complexity of the cutting mechanism increases

Engineering Contradiction:
Improvedisposal easeVSAvoidseparating device complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The separating device extracts only the necessary cutting function from the overall belt handling system. By positioning the cutting mechanism at a specific location in the collection area and using a straightforward disc-based cutting design, the system achieves frequent cutting capability without excessive complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system efficiently discards short finishing belt sections at predetermined intervals through the separating device. The simple disc-based cutting mechanism enables frequent disposal of small sections without requiring complex equipment, as each cut section is independently collected and removed from the system.

Inventive Principle:
Principle #34Discarding and recovering
