Machine safety

Safety engineered into every IROCUBE cell

From risk analysis to acceptance at your site, each cell is built on a documented safety concept. It is not assembled from a standard checklist.

  • Safety concept fixed before manufacturing starts
  • Every safety function tested at FAT and again at SAT
  • CE marking and risk analysis report with every cell
  • 14Safety standards referenced in design
  • CEMarked, with Declaration of Conformity
  • RiskAnalysis report for each cell
  • FAT + SATSafety functions validated twice

Why it matters

Robot, machine, conveyor and operator share one space

In a machine tending cell, the robot, the CNC machine, the conveyor and the people who run and service them use the same space at different moments. Each change between them is a safety scenario that has to be designed for.

Production, maintenance, fault recovery, part changeover and loading at the conveyor are separate safety states. Each one has its own speeds, interlocks and permissions. IROCUBE is designed for all of them.

Our safety concept starts in the design phase. Risk analysis, guarding layout, safety distances, control architecture and validation checklists are complete before manufacturing begins.

  • Designed in, not added on. Safety is part of the cell architecture from the first layout.
  • Every operating mode covered. Production, setup and maintenance each have defined rules.
  • Documented reasoning. Each safety decision traces back to the risk analysis.

Safety functions

Designed for every scenario in the cell

Each function is part of one integrated system. Components are positioned and rated in relation to each other, then tested before the cell ships.

Guard monitoring and locking

Every access door has a coded safety interlock. In automatic mode the robot cannot start unless all guards are closed and locked. Doors open only after the cell is in a safe state and the operator requests entry.

Emergency stop

E-stop buttons sit at every operator station and around the cell. The robot comes to a controlled stop before power is removed. Resetting an E-stop never restarts the cell on its own.

Safety control

Safety signals run through safety-rated relays or controllers with redundant, dual-channel wiring for critical inputs. The safety circuit works independently of the main cell control.

Robot safe zones and speed

FANUC DCS (Dual Check Safety) monitors robot position and speed against defined zones. In setup and maintenance the robot moves at reduced speed, controlled from a teach pendant with an enabling device.

Light curtains

Where loading stations or conveyor openings call for it, safety light curtains protect the access point. Their position is calculated from the robot's stop behavior, not estimated.

Conveyor openings and grippers

Conveyor pass-throughs in the fence are sized to keep hands out of the robot zone. Gripper air circuits are designed so a part is not dropped when power or air pressure is lost.

Standards framework

Designed with reference to machine safety standards

IROCUBE cells are designed with reference to the European and international standards below. Which ones apply, and how, is evaluated for each project based on layout, robot model, access points and site conditions.

Validation

Tested and recorded, not only designed

Every safety function is checked twice: at our facility before shipment, and again in your plant after installation.

  1. 01

    Design review

    Risk analysis, safety function requirements, safety distances and guarding layout are reviewed and documented before manufacturing begins.

  2. 02

    Factory acceptance test

    At our facility, before the cell ships, we test each E-stop, door interlock, guard lock, request-to-enter sequence and restart prevention. Results are recorded.

  3. 03

    Site acceptance test

    After installation, all safety functions are verified again in your plant. Machine interface signals and site-specific access and maintenance scenarios are tested.

  4. 04

    Handover

    Validation records and documentation are updated and handed over with customer sign-off.

Documentation

What comes with every IROCUBE cell

CE marking is the result, not the process. Behind it is a documented record of how safety was engineered for your cell.

The EU Machinery Directive is being replaced by the EU Machinery Regulation 2023/1230. We follow this transition and update our risk analysis and documentation practice to match.

Common questions

Safety and IROCUBE

Is every IROCUBE cell CE marked?

Yes. Each cell is delivered with CE marking and a risk analysis report for the specific layout and operating modes.

Are IROCUBE cells certified by a third party to these standards?

IROCUBE cells are designed with reference to the listed European and international standards. The standards that apply are evaluated project by project. The list is not a third-party certification.

Can the safety concept be adapted to our plant?

Yes. The safety concept is finalized for each project, based on cell layout, robot model, machine interface, access points and site conditions.

What happens to safety during maintenance?

Maintenance is a separate operating mode. Guards can only be opened after the cell reaches a safe state, and the robot moves at reduced speed with an enabling device on the teach pendant.
