Custom Made Box Filler

Filling a corrugated box with a very thick product was dangerous until we built this special filling machine. It includes a heat-jacketed infeed, ball valve and lance. A protective steel booth is built around the filler because the hot and sticky liquid can splatter.

Product Details: Item No. 806

Model: CMF-500

Capacity: 30 boxes per hour, 40 lbs each

Container: Corrugated box, 23” x 11” x 10” with a special poly liner inside

Material: Carbon steel construction, all wetted parts use 316 stainless steel


Add to Comparison


This customer, a leader in liquid sealants, wanted to fill corrugated boxes with a very thick liquid. The viscosity of the liquid was equivalent of glue and each box had a special poly liner inside. We designed a special semi-automatic, liquid filling machine with electric, heat-jacketed piping infeed, a three-inch ball valve and lance, and a protective steel booth built around it because the hot and sticky liquid would often splatter on the operator. At the filling station the operator could watch the filling cycle and discharge the load to a tape sealing machine.

Description of Operation

Empty corrugated boxes with a poly liner accumulate on a powered roller conveyor before the filling machine. The open boxes are indexed into the filler automatically, after a filled box is discharged by the operator. Each box stops when it reaches a photo eye inside the filling machine booth. The operator will press the start button to begin the fill cycle. The infeed manifold, ball valve and filling lance are all heat jacketed to keep the product hot and flowing. A scale under the fill station conveyor will tare to zero weight then the infeed valve opens allowing the heated liquid to flow into the box. As the scale reads the weight, it signaled the fill cycle to stop at the exact amount of net weight poured into the box. The lance rises to its home position then a pneumatic “air knife” activates to blow any residue off the end of the lance. The operator will discharge the box where it conveys past a light tree, signaling the next empty box to enter the filling booth.

Technical Specifications

This is a heat-jacketed, top-fill, semi-automatic, liquid filling machine with a safety enclosure to prevent the operator from the danger of hot liquid splash-back, with the following components:

  • All wetted parts are made from 316 stainless steel
  • 3” dia. ball valve and lance, electric heat-jacketed
  • Air cylinder to raise and lower the lance assembly
  • A 500 lb Rice Lake scale base with load cells
  • Scale accuracy, plus or minus 0.10 lbs on 3 a sigma curve
  • NTEP approved scale and weight meter
  • PLC controller, programmed and cycled tested
  • Electronic display, operator friendly keypad for data entry
  • Communications port for interface with Drum Filler in the Cloud
  • Automatic zero tare for each box before fill cycle begins
  • Powered roller conveyors before, inside and after the filling station
  • Photo eyes to recognize each box arrival
  • Safety interlock; no box, no start of the fill cycle
  • Light tree before and after the fill station
  • Lance crash protection, auto abort at 10 lbs force
  • Special steel splash booth with plastic windows at top and front

Fillers and conveyors are made with structural steel stanchions, frames and supports welded together, making each section a one-piece superstructure, the most rugged standard in the industry.
