Automatic Drum Filling System
This is a fully automatic, drum filling, bunging and capping system built to operate 24/7 filling liquids into 55-gallon drums. System shown without sliding guards.
Product Details: Item No. 1292
Rate: 60 drums per hour
Container: 55 gallon tight head steel drums
Material: Carbon steel construction, all wetted parts are 316 stainless steel
This three-station automatic drum filling machine is capable of filling 55-gallon steel drums at a rate of one per minute, (60 drums/hour) using water pumped in at 80GPM. Here is an unguarded view of the entire three-station filling system. The frame is a solid, one-piece welded superstructure made of structural channels and square tubing. A control panel at the end of a catwalk allows access to the controls and reprogramming while the machine is in full view. Maintenance has access to all the stations from below, above and both sides of this system. Sliding safety doors are sliding side to side type, not shown. This system consists of three stations:
- The rotator and bung removal station
- The filling station
- The bung replacement and capping station
Description of Operation
Empty drums are placed on the infeed conveyor and accumulate to an automatic escapement. The escapement device is used to hold back each drum until the filling machine calls for a drum to advance. Each drum will them be conveyed into the bung removal station.
At the bung removal station, the drum is lifted then rotated to locate the bung at the six-o’clock position. The drum is held in position while a special air-operated tool is lowered to remove the bung plug. After removing the bung, the drum is lowered and conveyed to the filling station. The loose bung is sent on a small conveyor to the bung replacement station at the end of the line. Each bung will be replaced onto the drum it was attached to when it arrived.
The drum is lifted off the conveyor at the filling station. The machine will then automatically tare the drum to zero weight and start the fill cycle. In the sub-surface mode, the lance travels to the bottom of the drum to control foaming. One of the two valves remain partially closed until the liquid reaches the tip of the lance. This is the slow fill mode. If filling a non-foaming liquid, the lance will only insert two inches into the drum. Both valves then open wide for fast fill mode.
Filling continues until a predetermined weight is achieved then the slow fill valve is activated to top-off the drum and achieve the greatest accuracy, eliminate splash-back and minimize foam. The lance rises to its home position where a pneumatic drip pan device catches any remaining liquid. The drum is then lowered and conveyed to the bung and capping station.
At the bung and capping station, a bung tool installs the original bung plug with the proper torque. Then, if needed, a dust cap is automatically placed and crimped onto the drum. When finished, the full drum conveys out to a delivery conveyor line.
