Okuma MS-320H Loading: Overhead Access and the 5.3-Second Example

The example reports 5.3 s loading/unloading.

Technical application analysis. Paired workpieces in the cited size examples; Okuma MS-320H; overhead manipulator with top-door coordination.

Reference configuration and timing

The example reports 5.3 s loading/unloading.
Separate part sets are Ø250 × L80 mm at 8 kg × 2 and Ø150 × L120 mm at 4 kg × 2.
A 0.5 s top-door statement describes door motion rather than the whole exchange.

Engineering evaluation

Check the combined height of workpiece, gripper and fixture along the overhead approach. Door position and surplus travel can dominate an otherwise short non-cutting interval.

A fixed loader and a mobile robot create different scheduling assumptions. Establish batch size, changeover frequency and machine-sharing needs before comparing their exchange or setup claims.

Selection conditions and evidence limits

Parameters belong to the cited examples and cannot be mixed between part sets. Conflicting feed and tool-storage details are excluded; current configuration requires builder confirmation.

Application questions

Does the half-second door time include loading?

No. It concerns a door action only.

Why keep the two part-size examples separate?

Mass, dimensions, gripping and acceleration constraints differ; combining one size with the other mass would create an unsupported specification.
