Automatic Pouring Machine

自動注湯機

The latest automatic pouring machine of Fujiwa Denki uses existing ladle and automates
the current pouring procedures.

The latest automatic pouring machine of Fujiwa Denki controls pouring by the VN control
system, automatic control system by load cells, and teaching system.

Especially VN control system which controls 3 axes of ladle enables automatic pouring with existing ladle.

Automatic Pouring Machine FVN Series

自動注湯機FVNシリーズ

Characteristics

Energy Saving / Automatic pouring procedures of skilled operators

・ Pouring procedures of skilled operators is automated as it is.
・ Production matching to the melting furnace is available by avoiding waiting time for pouring.

Energy Saving / Automatic pouring procedures of skilled operators

・ Pouring procedures of skilled operators is automated as it is.
・ Production matching to the melting furnace is available by avoiding waiting time for pouring.

Existing ladle is usable.

・ Shape of the ladle is flexible.
・ Ladle which is currently used is also usable.

Compact & Low Cost / Installation & Trial Run in a short period

・ Compact design enables easy integration into the existing molding line.
・ Installation period is short and quickly contributes to production.

Saving Rare Earth Elements

Inoculant is directly charged into metal stream in a required amount.

VN Control – Automating pouring procedures of skilled operators

ll 3 axes of tilting, up/down, forward/backward of the ladle are controlled by servo motors and pouring metal stream is controlled constant.

Teaching System – Automating pouring procedures of skilled operators

ティーチングシステム ―熟練者の注湯作業を自動化

Only the initial teaching of pouring speed is done by the worker. When pouring program is acceptable, then teaching program is registered.
The optimum pouring program by teaching is repeated in the same patterns since then.
Teaching less pouring is also available by simply setting pouring weight, pouring time, and latent pouring coefficient.

Anti-sloshing Control – Achieving high speed pouring

High speed metal transportation & pouring and improvement of pouring precision are obstructed due to metal surface waves produced in automatic
pouring machine or during metal transportation. The anti-sloshing control is the technology to suppress the waves of molten metal surface.

制振制御 ―高速鋳込み作業を実現

Weighing System – Achieving highly precise pouring weight

Weight reduction in the ladle is measured by load cells and pouring is stopped at predetermined pouring weight in each mold. High precision measuring speed is ensured with statistical processing of measured values of load cells.

ウェイングシステム ―高精度な鋳込み重量を実現
