Robot Unload, Blow-Off and Reload: Separating 90 s Cutting from Handling

The source groups unloading, blow-off, blank loading and restart into 18–22 s.

Technical application analysis. Fed cnc workpieces; geometry unspecified; CNC machine, exact type not established; robot with feeding and fixture-cleaning actions.

Reference configuration and timing

The source groups unloading, blow-off, blank loading and restart into 18–22 s.
Its 90 s machining example does not clearly establish whether exchange is included.
BRTIRUS denotes a robot family rather than the CNC machine brand.

Engineering evaluation

Split outside preparation from activity inside the machine. A robot can fetch the next blank during cutting, but normally cannot retrieve the current part until completion and safe entry. Do not assume all 18–22 s disappears inside 90 s.

Validate blow-off by remaining chips and successful seating, including cleaning retries. Select a bowl feeder or track around actual part orientation and surface requirements, with missing-part detection.

Selection conditions and evidence limits

Utilization and three-shift promotional scenarios are not customer guarantees. Robot repeatability is not a substitute for finished-part inspection.

Application questions

Should the complete robot sequence be added to 90 s?

Only a verified timeline can show which portions overlap and which stop the machine.

Why retain cleaning retries?

They occupy real production time and reveal whether the fixture can seat parts reliably.
