木材加工用圓盤鋸安全性能評估

Study on Safeguard Testing Methods and Codes for Woodworking Saw

本研究計畫之目的，即在於對木材加工用圓盤鋸安全防護裝置，建立一套可行之試驗辦法，測試其性能是否符合機械器具防護標準之規定。研究方式係透過木材加工用圓盤据相關安全裝置資料之蒐集，分析其安全防護裝置和職業災害的相關性。並且透過調查、訪問的方式，以瞭解國內圓盤据安全防護裝置製造及使用的現況。最後建立一套圓盤鋸安全裝置性能試驗方法，提供給有關廠家參考，期能減少操作勞工的機械傷害。本研究發現較新型之圓盤鋸安全防護裝置，均未裝制動裝置及反抛防止爪，該兩項是否列入機械器具防護標準值得商榷。同時圓盤据安全防護裝置之設計確有不夠理想之處，製造廠商實應投入研發經費，改良安全防護裝置之實用性，以提高產品價值。

The purpose of this project was to establish a method for examining whether safeguarding devices on woodworking radial saw used in the industry met the requirements of mechanical safeguarding codes. In order to study the properties of these safeguarding devices, this research also developed a protocol for testing safeguarding device capacity, through surveys, interviews and performance testing. It was found that most of the new types of woodworking radial saws did not install the 'braking equipment' and anti-kickback pawls required by mechanical safeguarding codes. The results of this study indicated safeguarding devices could not only protect the operator against the injuries, but also could increase the value of the products. The methods for testing the performance of safeguarding devices will be provided to manufacturers and users as a reference to decrease the injuries caused by woodworking saws.
