Light Curtain Safety Devices. Safety light curtains are photoelectric presence sensors specifically designed to protect personnel from injuries related to hazardous machine motion. Light curtains offer optimal safety, yet they allow for greater productivity and are the more ergonomically sound solution when compared to mechanical guards. The minimum safety distance is defined as the minimum distance from the light curtain's plane of light to the closest hazard or danger point where the operator could reach into the hazard. This minimum safety distance is based on the stopping ability of the machine and a hand speed constant.

Use of horizontal light curtains at operator train station
HeIlo, I'll try out and paint a very clear image of this. I have always been attempting to determine is if horizontaI light curtains are usually furthermore 'required'. I can't discover anything in the criteria that provides me clarity, I don't possess ISO13855 even though, but that shows up to only offer with safe stopping distances, which I understand how to estimate.
Consider a single robot cell with a twó position turntable, sides A and B. When Aspect A is definitely at the agent, the strength should be eliminated from the mop of the table. The automaton will weld, or do whatever on part M until the operator finishes loading side A new. As soon as the user has left the mobile and resets thé curtains, the table should mop.
So the user has strolled through a collection of straight MANUAL reset light curtains, and is definitely loading components, having them just be straight methods they are in an open zone between the Iight curtains and desk. Getting them become manual reset means the agent provides to keep the cell to reset and begin procedure.
Mainly because considerably as I can tell, I meet up with safety criteria with this setup, assuming one user, and the operator has obvious view of the loading area from the reset/begin place.
I observe regularly (and we possess done these simply because well) angled light curtáins at the agent entrance region, which essentially addresses the entire operator area and pads the light curtains simply because very long as an owner can be in the launching area. Also getting cascaded pieces of a straight and horizontal pair to accomplish the exact same matter. But are these 'essential'?
I'm trying to figure out when the horizontal region should become protected. And if it actually needs to become covered in a solitary operator mobile with very clear sight of the cell.
If the automatic robot and user were to become sharing the same work surface area, after that I can observe even more of a want for the horizontals, but only if auto reset has been being utilized.
What are usually your ideas? Is certainly this even more of a 'very best practice'?
