Overview

This automatic pail filler was designed for filling open-top, five gallon pails with a viscous liquid in a three-shift operation. Empty pails accumulate to an escapement device and are released when the pail filling machine discharges a full load. The powered conveyor after the filler is for placing lids onto filled pails before they run through the on-the-fly lid press.

An air operated, metal lid crimping device with a cable reel and coiled air line is hanging from a monorail to secure the lids onto occasional metal pails. The monorail allows all pails to continue moving during the securing of the metal lid, or placement of the plastic lids.

The on-the-fly lid press at the end of the line kneads the plastic lid onto the pails as they convey through the tunnel. The tunnel height is adjustable for 4 to 7 gallon containers.
