2826 自动化中断

随着越来越多的自动化装配线的建造和旧线路的自动化，需要考虑与机器相互作用的人员的安全性。
保护操作员免受不断移动的机器的危害，并且没有适当的传感器，不知道他们周围的人的行为，不需要花费很多。
但是，所需的设备需要高度可靠。

这就是LED的用武之地。它们成本低廉，与易于编程的控制电子设备相结合，可用于制造光幕，可以检测可能危及其安全的无意操作员操作。
此外，这些安全光幕能够配置为支持各种机器，并且在必要时可以有效地重新配置。
一旦任何物体中断光幕中的光束，控制电路就会立即关闭机器，这可能会对操作员造成严重伤害和/或损坏昂贵的设备。

Safety具有全系列型号，特别是F3SG系列，可配置为适合许多安全应用。
松下工业自动化销售部还有SF4B系列。
此外，Digi-Key还有一个相对较新的光幕供应商，即SICK，目前有两个系列的光幕，deTec4 Core系列和C4000 Select系列。
deTec4 Core系列提供300 mm至900 mm的保护高度，而C4000 Select系列则提供600 mm至1800 mm的保护高度。
此外，对于那些感兴趣的人，Digi-Key有几篇文章更详细地讨论了光幕，“轻松实现机器安全”和“危险 - 保持不变;
用于工业防护的安全额定传感器“。
随着工业自动化的兴起，必须特别注意确保可能在该地区的任何人员的安全。
为此，光幕可以成为任何自动化工厂安全的可靠组成部分。

With more and more automated assembly lines being constructed and older lines being back-fit for automation, the safety of the personnel interacting with the machinery has to be considered. Protecting operators from the hazards of machines that are constantly moving and, without proper sensors, oblivious to the actions of humans around them doesn’t have to cost a lot. However, the equipment required needs to be highly reliable.

Here’s where LEDs come in. They are low cost and, when combined with control electronics that are easily programmable, can be used to create light curtains that can detect inadvertent operator action that could jeopardize their safety. In addition, these safety light curtains are capable of being configured to support a wide variety of machinery and, when necessary, be efficiently reconfigured.
Once any object interrupts the light beams in a light curtain, control circuitry could instantly shut down machinery which could potentially lead to serious hARM to operators and/or damage to expensive equipment.
Omron Automation & Safety has a full range of models, specifically the F3SG range, that can be configured to suit many safety applications. There is also the SF4B Series from Panasonic Industrial Automation Sales. Additionally, there is a relatively new light curtain supplier at Digi-Key, namely SICK, that has two series of light curtains currently available the deTec4 Core Series and the C4000 Select Series. The deTec4 Core series offers protective heights from 300 mm to 900 mm while the C4000 Select Series offers protective heights from 600 mm to 1800 mm.
Furthermore, for those of you that are interested, Digi-Key has a couple of articles that discuss light curtains in greater detail, “Making Light Work of Machine Safety” and “Danger – Keep Out; Safety-Rated Sensors for Industrial Guarding”.
With the rise of industrial automation, special care must be taken to ensure the safety of any personnel that may be in the area. To this end, light curtains can be a reliable component of safety of any automated factory.
