Safety¶
Stackmill moves an industrial robot
Everything on this site describes software that commands a machine capable of causing serious injury. Nothing here replaces the safety equipment of your cell, the training of the people using it, or your own risk assessment.
Before anything else¶
- Nobody inside the fence while the cell can move.
- The physical emergency stop is the emergency stop. The soft stop in the software is a convenience and depends on software and a network being alive.
- Anyone who may move the robot by hand must be trained for it. That page is written for trained staff and says so.
What Stackmill does not do¶
It is not a safety system, and it is not certified as one. It does not:
- detect people, or know that anyone is in the cell;
- replace the guarding, the interlocks, the light curtains or the safety controller;
- override the robot controller's own safety functions, which remain in charge.
Collision checking, work zones and trajectory validation exist to protect your parts and your cell from programming mistakes. They are a design aid, not a protective device.
A simulation is not a proof¶
A simulation is exactly as right as what it was told. A robot mounted a few centimetres from where the project says, a tool whose measurements were typed in wrong, a pallet not where the cell believes — each of these produces a simulation that runs perfectly and a cell that does not.
Run a new program slowly the first time, and watch it. Speed changes only the speed, never the path, so a slow first run tells you the truth about the path.
Your responsibilities¶
Commissioning an industrial cell, assessing its risks, guarding it and declaring its conformity are the responsibility of whoever puts it into service. If you are not sure what that means for your installation, ask us before you commission it — that conversation is part of what we sell.
