Oil Filling Assembly | An Automated System Solution for Generator Engines

Updated: Sep 9, 2024

Case Summary:

A generator manufacturing company came to GP Reeves looking for a more effective, efficient, and reliable filling solution for their generator engines. Our customer had three different generator models featuring two different engines that required repeatable oil filling. GP Reeves was able to create a system that recognized the varying generators and could handle their specific dispensing needs. By combining a robotic, vision-driven system with our dispensing expertise, GP Reeves developed a dispensing solution that enabled the OEM to simplify their generator manufacturing process.

The Problem: Inefficient Generator Filling

The developer’s production process required different generator models to be directed to the same fill station. Previously, an employee manually filled each generator engine with oil using a handheld dispenser. Although the oil was measured, the manual nature of the process introduced the risk of engines being overfilled, underfilled, or even missed entirely. This method also required dedicated manpower, diverting resources that could be more effectively utilized elsewhere. Furthermore, it increased the likelihood of spills and human error. The manufacturer needed a more efficient, accurate, and repeatable dispensing solution to streamline the oil-filling process while reducing labor time and minimizing potential errors.

The Challenge: Unreliable Generator Placement

As the generators moved down the assembly line, there was no fixed orientation for how each module was positioned. The generators were placed on skids that traveled along the conveyor, creating a significant margin for error. This meant our system had to be smart enough to accurately identify the location of the fill port, regardless of the generator’s orientation. By doing so, the system ensured proper oil dispensing and minimized the potential for wasted material.

Conveyor Configuration

The Solution: Repeatable and Accurate Dispensing

GP Reeves provided the customer with an automated dispensing system capable of precisely filling their different generator engines. The two engine models required 1.4 and 1.9 quarts of material, respectively, and the system was able to dispense each volume in a single shot, completing the filling process in less than 70 seconds per engine. The system featured a 6-axis robot integrated with a vision system and an ultra-precise AA9 servo dispenser. This dispenser fed an end-of-arm tool that ensured material reached the correct dispense point. The AA9, used for this application, allowed the dispense rate and volume to be controlled by a fully programmable PLC, working seamlessly with the 6-axis robot and vision system.

The filling process was straightforward: the system scanned each generator as it entered the cell on the conveyor, confirmed the generator model, located the fill ports, and dispensed the exact amount of oil required. The fill volume tolerance was +/- 1%, equating to less than 2cc per fill. For one of the generator models, the total oil volume had to be distributed between two separate ports to prevent overflow. The system recognized each port and accurately dispensed the appropriate portion of the total volume. This customized generator solution showcased GP Reeves’ ability to tailor systems for any application. The automated system ensured that no generator passed through the cell without being properly filled, providing the customer with confidence that every engine received the precise amount of oil.

End Result: Recognizable Reliability

GP Reeves delivered an automated dispensing system that improved the OEMs assembly line efficiency. With this customized system, we were able to provide our customer with the ability to precisely fill their various generator models. The flexibility of this system also allows for additional models to be added in the future if necessary. Our dispensing solution led to increased productivity, decreased downtime, and labor savings. The customer was thrilled with the final system provided and plans to implement multiple other GP Reeves systems in the future.
