Shot Treatment Device Rotary Table Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shot treatment devices have complex structures due to the need for detector protection panels and mechanisms, which hinder efficient cycle time management and prevent simultaneous processing of multiple workpieces.
Innovation Solution
A shot treatment device with a rotary table and multiple chambers allows for simultaneous loading, unloading, and inspection of workpieces, with inspection detectors capable of ascending and descending in separate chambers, and a blower for dust removal, simplifying the structure and enhancing processing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If an inspection detector is built in the treatment chamber, then inspection can be performed during shot peening, but the structure inside the treatment chamber becomes complex due to detector protection panels and mechanisms
Solution Approach 1:
The device is divided into multiple independent chambers (shot peening chamber, first inspection chamber, second inspection chamber, loading chamber, unloading chamber) arranged around the rotary table. Each chamber has a specific function, allowing inspection processes to be separated from the shot peening process. This segmentation eliminates the need for complex detector protection mechanisms within the shot peening chamber while maintaining continuous production capability.
Solution Approach 2:
The inspection detector is extracted from the shot peening chamber and placed in a separate first inspection chamber. This extraction removes the detector and its protection mechanisms from the shot peening environment, simplifying the shot peening chamber structure while enabling continuous inspection through the rotary table's multi-chamber configuration.
2Reliability
If a detector protection panel and pivot mechanism are provided, then the inspection detector is protected during shot peening, but the structure inside the treatment chamber becomes more complex
Solution Approach 1:
The inspection function is segmented into separate chambers (first inspection chamber and second inspection chamber) distinct from the shot peening chamber. This spatial segmentation eliminates the need for detector protection panels and pivot mechanisms within the shot peening chamber, as detectors are positioned in dedicated inspection chambers where they operate in a controlled environment away from shot media.
3Productivity
If multiple workpieces are to be processed simultaneously, then cycle time is reduced, but the treatment chamber structure becomes more complex
Solution Approach 1:
The treatment device is segmented into multiple chambers (shot peening chamber, first inspection chamber, second inspection chamber, loading chamber, unloading chamber) arranged around the rotary table. Each chamber handles a specific stage of the workpiece processing cycle, enabling multiple workpieces to be at different stages of processing simultaneously. This segmentation achieves parallel processing without requiring complex internal structures within any single chamber.
Solution Approach 2:
The rotary table serves as a universal platform that supports multiple placement tables, each capable of holding a workpiece. The rotary table enables continuous movement of workpieces through different chambers, providing multi-functionality that supports simultaneous loading, shot peening, inspection, and unloading operations without requiring separate dedicated structures for each function.

AI summary
A shot treatment device includes a cabinet, a plurality of chambers provided in the cabinet, a rotary table rotatable in a first rotation direction about a first rotation shaft extending along a vertical direction, a plurality of placement tables arranged at intervals in a circumferential direction on an upper surface of the rotary table, each of the plurality of placement tables being configured to receive and hold a workpiece, an ejector configured to eject shot media, and a first inspection detector configured to inspect surface properties of the workpiece. The plurality of chambers are arranged side by side around the first rotation shaft and include a shot chamber in which shot media is ejected to a workpiece and a first inspection chamber provided downstream in the first rotation direction from the shot chamber, the ejector ejects shot media to a workpiece held on a first placement table that has entered the shot chamber, and the first inspection detector capable of ascending and descending is disposed above a second placement table that has entered the first inspection chamber and inspects surface properties of a workpiece held on the second placement table.
