Automatic Lubricant Oil Filling Machine

Precision Volumetric Filling Systems for the Automotive and Petroleum Industries

In the highly competitive lubricants and industrial fluids sector, production efficiency relies on accuracy, speed, and clean operation. Liquid packaging lines facing the high viscosity of engine oils, gear oils, hydraulic fluids, and synthetic lubricants require heavy-duty engineering capable of managing dense liquids across fluctuating temperatures.

The Automatic Lubricant Oil Filling Machine manufactured by Harsiddh Unimach Pvt. Ltd. represents the pinnacle of modern liquid packaging technology. Engineered specifically to replace outdated pneumatic setups, our advanced filling systems utilize state-of-the-art servo-driven gear technology to ensure impeccable volumetric accuracy, reduced product giveaway, and maximum throughput. Built in strict accordance with cGMP standards, this robust machinery is designed to withstand the demanding, continuous-duty environments of modern petroleum blending and packaging facilities.

The Challenge of Lubricant Packaging: Why Servo Technology Wins

Lubricants present unique challenges during the automated filling process. Unlike free-flowing water or alcohol-based liquids, industrial oils exhibit high viscosity and density profiles that shift noticeably based on ambient factory temperatures. Traditional pneumatic or gravity-fed systems often struggle to maintain consistency when a batch of oil cools or warms, leading to overfills that waste costly product, or underfills that violate regulatory compliance.

Harsiddh Unimach Pvt. Ltd. solves this industry-wide challenge by integrating precision servo-gear technology. By replacing standard pneumatic pistons with electronically controlled servo motors, the machine achieves unparalleled control over the dosing cycle.

• Temperature-Independent Accuracy: The encoder-controlled servo drives deliver a fixed volume of lubricant regardless of changes in oil density or ambient temperature.
• Programmable Profiles: Operators can digitally adjust filling speeds via a centralized touchscreen interface to match the unique flow characteristics of different oil grades—from thin synthetic blends to thick heavy-duty gear lubricants.
• Minimized Wear and Maintenance: Mechanical stress is vastly reduced compared to pneumatic cylinders, leading to longer component life and decreased operational downtime.

Comprehensive Sequence of Operation

Our automatic lubricant oil filling machinery features a fully synchronized, linear workflow that seamlessly integrates into existing downstream packaging lines. Every step of the process is optimized to keep containers moving smoothly while eliminating product spills.

1. Automated Container In-feed and Indexing

Empty containers (ranging from rigid plastic HDPE bottles to tin cans) travel along a high-grade Stainless Steel (SS) slat conveyor. A specialized twin-pneumatic stopper and gating system accurately counts and spaces the incoming containers. This ensures that a precise batch of bottles is locked into position directly beneath the filling nozzles, preventing accidental collisions or misalignments.

2. Intelligent Photoelectric Bottle Sensing

To prevent catastrophic oil spills and mechanical failures, the system is equipped with advanced photoelectric sensors. These sensors perform a continuous electronic audit of the filling zone. If a container is missing, fallen over, or improperly positioned, the “No Bottle – No Fill” safety protocol triggers instantly. The machine skips that specific station, preventing oil from dispensing onto the conveyor bed.

3. Bottom-Up Diving and Dosing Mechanics

High-viscosity oils are prone to air entrapment, turbulence, and severe foaming if dropped into a container from a height. To counteract this, our machine utilizes an automated diving nozzle mechanism. At the start of the filling cycle, the nozzles descend deep into the base of the container. As the servo-driven fluid delivery begins, the nozzles gradually rise in tandem with the liquid level. This bottom-up filling technique maintains a smooth, laminar fluid flow, eliminating air bubbles and foam formation.

4. Crisp No-Drip Cutoff and Suck-Back Action

Oil dripping onto bottle necks or outer walls ruins product presentation and compromises downstream processes like induction sealing and labeling. Harsiddh Unimach Pvt. Ltd. implements custom-designed pneumatic shut-off nozzles featuring an active suck-back mechanism. The moment the target volume is reached, the nozzle valves snap shut instantly while a slight reverse vacuum pulls residual oil droplets upward back into the nozzle tip. This guarantees a clean, residue-free break between cycles.

5. Synchronized Discharge to Downstream Machinery

Once the precise volume is filled, the pneumatic gating system opens smoothly, allowing the filled containers to accelerate down the conveyor lines. The bottles move seamlessly toward the next automated phases of your production floor, including automatic capping, induction cap sealing, batch coding, and high-speed labeling.

Key Technical Features & Engineering Excellence

• cGMP-Compliant Construction: All structural components, frames, and outer covers are fabricated from premium-grade Stainless Steel (SS 304). All fluid-contact parts, piping, and valves are crafted from superior SS 316L to resist chemical degradation and ensure long-term durability.
• Flexible Multi-Head Configurations: Available in multi-nozzle configurations (such as 4, 6, 8, or 12 heads) to align perfectly with your facility’s daily production quotas.
• Toolless Changeovers: Minimize your changeover downtime when switching between different container sizes or shapes. Universal adjustments can be made rapidly without requiring specialized tools.
• Advanced HMI Control Panel: A user-friendly, color touchscreen Human-Machine Interface (HMI) allows operators to store multi-product recipes, adjust fill volumes on the fly, monitor real-time production statistics, and diagnose system faults immediately.
• Integrated Variable Frequency Drives (VFD): The conveyor tracking system utilizes premium VFDs to smoothly control start-and-stop sequences, ensuring heavy, freshly filled oil containers do not tip over during transport.
