SCARA robot sorts recyclables using a simple conveyor speed feedback system

encoders for conveyor systems and robots

Background

Everest Labs, based in Fremont, California, is a cutting-edge company developing AI-powered systems for waste management. At the heart of their innovation is a SCARA robot that uses AI to sort materials as they move along a conveyor belt. The robot relies on precise tracking to distinguish recyclables, making accurate speed feedback from the conveyor critical to the system’s success.

To enhance their system for global recycling centres, Everest Labs sought a reliable encoder solution that could be easily integrated with their gear motors, ensuring smooth operation and adaptability across varied environments.

The Problem

Everest Labs needed a way to provide their SCARA robot with consistent conveyor speed feedback to improve efficiency in sorting recyclables. However, their setup presented several challenges:

  • The conveyor gear motors used by different customers often featured varying configurations, making compatibility essential.
  • Most motors had a back shaft that was exposed but too flush to mount an encoder directly. Drilling and modifying the shaft was a possible solution but was time-intensive and risked voiding the motor warranty.
  • The encoder needed to be protected from environmental hazards like debris and collisions while ensuring simple, fast installation.

Recognizing the challenge, Samir Kamat, an engineer at Everest Labs, reached out for advice. Ryan Money, an engineer from Kaman Automation (a distributor of EPC products), visited the facility to assess the issue and explore potential solutions.

The Solution

After some consideration, a solution was found: the Model 58T/HF could be mounted with a magnetic coupling and a Uni-cover, along with a customer-supplied adaptor plate for securing the encoder.

Everest Labs chose the Model 58HF because of its compact size, metal housing, and IP67 seal – which protects the encoder in applications where water is present. The magnetic coupling was selected because it allows fast, easy installation on almost any motor shaft likely to be encountered on-site. The Uni-cover was selected for safety for operators working around the equipment, and to protect the encoder from debris and impact hazards from forklifts or other equipment.

After the Model 58T/HF was installed with the magnetic coupling, Uni-cover, and customer-supplied adaptor plate, and testing was completed, Samir and Ryan reported that the machinery was working consistently and reliably.
