Automatic filling machine EL2-B

drumliquidsdrum

Overview
The EL2-B is a sequential in-line automatic drum filler. Drums advance station to station; each operation runs in parallel on different drums, enabling throughputs up to 130 drums/hour. The operator only loads empty drums at the infeed and unloads full drums at the outfeed; containers are not manually handled during the process.

Main capabilities

• Sequential in-line operation with independent filling stations and per-station weighing to net weight.
• Suitable for steel or plastic drums from 60 to 250 L.
• Typical stations: centring, uncapping, purging (inert gas), filling, capping, sealing; configurable up to 6 stations.
• Independent dosing group, nozzle and weighing scale per filling station for controlled net fills.

How it works

• Operator selects recipe, net weight and container format on the HMI.
• Machine is set to format: guides, nozzle position and cap feed where fitted.
• Empty drums accumulate at the infeed and enter the machine sequentially.
• Drums transfer through stations (centring, uncapping, purging, filling, capping, sealing) as configured.
• Each filling station fills to the configured net weight on its own scale; filled drums exit on the outfeed conveyor.

Operating stations and functions

• Drum centring: arms hold and rotate the drum; sensor detects the bunghole and orients the drum.
• Uncapping: head unscrews cap and deposits it on a cap conveyor so the same cap is refitted on the same drum.
• Filling: dedicated dosing group, nozzle and scale sized for full drums.
• Purging: inert gas lance for pre-fill inerting when required.
• Capping and sealing: automatic screwing with adjustable torque; floating head compensates misalignment and height differences.

Filling assemblies and modes

• Two filling assemblies available: under-bunghole or immersion (sandblasted AISI 304 frame, standard nozzle AISI 316L).
• Immersion assembly supports three recipe-controlled modes:
  • Rising with the product: nozzle opens at the bottom and rises as the drum fills, maintaining nozzle at product level.
  • From the bottom: nozzle remains at lowest position for highly foaming products.
  • Under-bunghole: nozzle enters just past the bunghole and fills from that position.

Inert gas filling (optional)
Accessory delivers inert gas through the nozzle or via capping assembly overpressure. Gas flow is driven by a solenoid controlled from the cabinet; timing and duration are recipe parameters to reduce oxygen exposure and limit ignition risk for flammable products.

AiCROVFill® software features
Recipe-based operation, per-station final weight control, automatic top-up after nominal weight, compensation for submerged lance volume during immersion filling, automatic learning/compensation of product fall after valve closure, and independent weighing per filling station.

Machine architecture
In-line structure with a transfer system moving drums between stations. Each filling station includes a load cell, summing box and weighing channel integrated in the control. Machine integrates with roller conveyor lines and requires quoted accumulation conveyors at the infeed/outfeed.

Safety and compliance
Designed and manufactured in Europe. CE marking is the starting point. Risk assessment and design follow EN ISO 12100; safety parts of control systems to EN ISO 13849-1; electrical equipment to EN 60204-1; emergency stop to EN ISO 13850. Machine is fully enclosed with one interlocked door per position and tunnels at infeed/outfeed sized to allow drums but prevent access to the interior. Emergency stop, door interlocking, passive nozzle lock and safe behaviour on failure are included. Explosion-proof versions for Zone 1/2 are available as project-specific configurations.
