Bag-In-Box Filler

Product Description

Product contamination was the reason for this customer to fill a corrugated box with a plastic liner in it. This bag-in-a-box filler is a model DF-5541, drum and tote filling machine, modified to fill a plastic bag placed into a bulk box. The container to be filled may be a corrugated box, a plastic bin, a collapsible bin, or any another contaminate-free object. The primary modification is a special foot valve at the end of the lance to make the liquid flow like a faucet, instead of a shower. This spread-out flow of liquid eliminates wrinkles in the bag during the filling operation. Without it, the bag would likely collapse into the box. All the necessary controls to operate the filler and scale conveyor are on the handle in front of the operator. The other conveyors operate automatically by photo-eye recognition of loads.

In a similar application when the customer was filling a collapsible container with a liquid food additive, a spreader bar with a cam-lock clamp was provided. The aluminum spreader bar was placed across the width of the collapsible container to keep the sides upright during the filling operation, and also to hold the throat of the plastic bag in place during the fill cycle.

Specialty Equipment manufactures fillers and conveyors with structural steel stanchions, frames and supports welded together, making each section a one-piece superstructure, the most rugged standard in the industry.

Description of Operation

  • The filler is a model DF-5541 top filling machine
  • A plastic bag with a two inch diameter throat is contained in the corrugated box
  • The operator aligns the boom and lance over the throat/bung opening
  • By pressing the start button, the lance enters the bag.
  • The controller will automatically zero the tare weight before filling begins
  • A special foot valve on the lance allows liquid to flow like a faucet, rather than a shower.
  • The faucet flow limits the foaming and removes the wrinkles of the bag during the fill cycle
  • Without the proper valves and flow control, the bag could collapse in the box
  • When completed, the lance rises automatically to its home position
  • The operator discharges the load and another conveys onto the filling station
