Semi-automatic filling machine

bottlecontainerjerry can

Overview
The LSG fills jerrycans, bottles and equivalent containers from 1 to 30 litres by weight, one at a time. It is a semi-automatic plug & fill machine with a fixed nozzle, typical resolution ±5 g and capacity up to 150 containers/hour (for a 25 L container). The operator places the empty container on the weighing platform, aligns it under the nozzle and starts the cycle; the machine tares automatically, doses to the net weight and stops.

Is this the machine you need?
Recommended when individual containers under 30 litres are filled one at a time with manual loading/unloading by an operator. Not suitable for drums or IBCs (other models cover those formats) or for fully automatic inline high-throughput operations with multiple stations.

How it works

• Select filling recipe and net weight on the operator panel.
• Adjust filling height to the container format without tools.
• Place the empty container on the weighing platform.
• Align the container opening with the nozzle.
• On start the system tares automatically and fills to net weight.
• Remove the full container and place the next one.

Filling modes
Two filling assemblies are available (selected at order): under-bunghole or immersion. Both are stainless steel (AISI 304 structure, AISI 316L nozzle standard) with alternative materials available for demanding products.

Under-bunghole filling
Typically used for non-foaming, non-flammable products (including dense and viscous). The nozzle descends just inside the container and fills from that position; this assembly fills under the bunghole only.

Immersion filling
Used for foaming or flammable products. The nozzle descends to the bottom of the container; the recipe selects one of three filling behaviours:

• Rising with the product: the nozzle opens at the bottom and rises as the container fills, keeping the nozzle at the product surface until top level.
• From the bottom: the nozzle stays at its lowest position for the whole fill (for extremely foaming products).
• Under bunghole: the nozzle enters just past the bunghole and fills from there (equivalent to under-bunghole mode).

Machine architecture
Self-supporting structure with a column carrying the filling head, dosing group and actuation. The nozzle remains fixed while the container is positioned on the flat weighing platform. The weighing terminal is integrated into the control so weight governs the cycle directly. A quick centring device is available as an accessory for repetitive formats.

Inert gas filling (optional)
Available as an accessory to fill under an inert atmosphere. The nozzle carries a gas passage controlled by a solenoid valve in the control cabinet; gas timing and phase are recipe parameters (before opening, during filling, after target reached, or combinations). Nitrogen is commonly used but gas selection depends on the product. Overpressure inerting at capping is also an option.

AiCROVFill®
AiCROVFill® is the filling control ecosystem designed for accurate, repeatable operation with challenging products. Key functions include:

• Misalignment control: the nozzle returns to upper position if resistance is detected and waits for operator realignment.
• Final weight control and top-up: after nominal weight is reached the system monitors settled weight and reopens to top up if needed.
• Compensation for submerged lance: the control accounts for displaced volume so net weight is correct after lance extraction.
• Automatic compensation for product fallout after valve close: fixed or learned compensation over containers.
• Recipe-based operation: filling parameters stored per product and container format for repeatable changeovers.

Built from standard industrial components
The machine uses industrial components from global brands for control, pneumatics, sensors and weighing elements; no proprietary electronics or firmware in the control chain. This simplifies local spare sourcing and maintenance.

Safety and compliance
Designed and manufactured in Europe to European machinery safety legislation and supplied with CE marking as baseline. Design follows harmonised frameworks (risk assessment to EN ISO 12100; safety-related parts to EN ISO 13849-1; electrical equipment to EN 60204-1; emergency stop to EN ISO 13850). Safety features include:

• Emergency stop — cuts electrical power and pneumatic pressure simultaneously; manual reset.
• Passive nozzle lock — nozzle cannot open without pneumatic pressure; loss of air or power stops the machine with the nozzle shut.
• Safe behaviour on failure — no residual nozzle movement or product flow.
• Explosion-proof versions engineered for certification schemes (ATEX, IECEx, NEC) are available for hazardous areas.
