Packaging Cycle SFC | ChatDiagram

Packaging cycle SFC

This SFC shows a simple packaging cycle as four active phases. The machine waits idle, feeds a product, closes the sealer for a timed interval, and discharges the package. Transitions use the signals that confirm progress through the machine. The chart supports design discussions because it exposes the intended order of operations, while a working machine program also requires equipment-specific safety and fault logic. Before using the layout in a build or document, compare every label with the source requirements and update the drawing when parts, conditions, or materials change. The example is deliberately small so the essential relationships remain readable, easy to review with collaborators, and ready to extend with the details required for the actual project.

需求

“Create an SFC for a packaging cycle with idle, feed product, a two-second seal step, and discharge, advancing on product present, seal complete, and package clear signals.”

接著試試Add a reject step for failed seal inspection.Change the sealing delay to three seconds.

這張圖裡有什麼

看懂背後的決策。

01States

Feed, seal, and discharge are separated.

02Timed action

The sealer is held for two seconds.

03Feedback

Sensors confirm each advance.

Use for a high-level packaging sequence before adding detailed faults and safety controls.

常見問題

What is an SFC step?

It is an active phase in a sequential control process.

Why use a timed seal action?

It shows how long the seal command remains active.

What advances the chart?

The named sensor or completion conditions on each transition.
