SHIELDING DEVICE FOR A SAW， IN PARTICULAR A TABLE SAW， AND SAW EQUIPPED WITH SUCH A SHIELDING DEVICE， IN PARTICULAR A TABLE SAW

The invention is concerned with a shielding device ( 1) for shielding a saw blade (3) or band of a sawing machine against access by an operator and against ejection of workpiece parts， which can be attached to the sawing machine in such a way that， in a working position， it covers the saw blade (3) or band towards the operator. The shielding device (1) comprises a temperature monitoring unit (2) which has a temperature sensor (4).The invention is characterized in that the temperature sensor ( 4) operates without contact and， with the shielding device (1) mounted on the sawing machine and located in the working position， is directed towards the toothing of the saw blade (3) or band， and a display device (5) displays the surface temperature detected by the temperature sensor (4) on the surface of the toothing of the saw blade (3)， wherein the temperature monitoring unit (2) is formed as an autarkic operating unit and is mounted on the shielding device (1) such that it is detachable by an operator without tools.The invention is further concerned with a sawing machine with such a shielding device ( 1).

本发明涉及一种防护装置（1），用于对锯切机的锯片（3）或锯带进行防护，避免操作人员接触以及防止工件部件弹出，该防护装置可按如下方式安装至锯切机：在工作位置下，其朝向操作人员的一侧覆盖锯片（3）或锯带。防护装置（1）包括温度监测单元（2），该单元设有温度传感器（4）。本发明的特征在于：该温度传感器（4）采用非接触式工作模式，且当防护装置（1）安装于锯切机并处于工作位置时，其朝向锯片（3）或锯带的齿部；显示装置（5）将温度传感器（4）所检测到的锯片（3）齿部表面温度予以显示。其中，温度监测单元（2）构造成独立式运行单元，且以无需工具即可由操作人员拆卸的方式安装于防护装置（1）。本发明还涉及一种配备有该防护装置（1）的锯切机。
