Overview

This is a top-fill system with five gallon pails for non-foaming liquid products. Sub-surface systems are also available. Three rows of four pails are shown. The first row of pails is already filled and being conveyed to a lid press. The second row is positioned under the filling heads. The third row is accumulated behind them, ready to move in when filled pails move out.

The row of filled pails drives away where lids are automatically placed on top then they convey through a tunnel where lids are pressed on-the-fly. If a label is required, it would sequence after the lid press. The last machine in line is the automatic palletizer.

The fill rate of water is sixteen (16) pails per minute.

Description of Operation

This automatic pail filling system, model APF-541, is designed to fill four open top pails, simultaneously. The system includes a 10’ long, powered infeed conveyor line with four air-operated pail escapements that accumulate the pails then releases them to the filler, as needed. It also includes a 10’ long, powered discharge conveyor.

Four pails are conveyed and accumulated on the infeed conveyor behind the filling stations, spaced equidistant. When signaled, the escapements are released and the pails are lifted by a two-strand, chain conveyor and transported into the filling stations where they are lowered onto four individual scales under the filling lances. At the same time, four newly filled containers are conveyed out the front of the filling stations and four empty pails are conveyed and accumulated behind the fill stations.

Upon arrival, a photo-eye signals the computer to automatically tare the four containers to zero weight then start the fill cycle. At each filling station, both ball valves open wide for fast flow. Filling continues until the pre-designated weight is achieved in each container.

Near the top, the slow fill valve activates to top-off the containers. When completed, the weights are calculated and recorded. The containers are then raised and conveyed out of the filling stations to make room for four empty containers to enter from the back. The cycle then repeats

The filling rate of this machine, using water as the tested product, is 16, five gallon open-top containers per minute.
