Case Study

Programmable Model 25SP Saves the Day

Background

As we were setting up our exhibitor’s booth at Pack Expo in 2018, we were approached by Craig DeMello, Application Engineer for Soft Robotics in Bedford, Massachusetts. Soft Robotics enables robotic automation for large markets and labor-starved industries such as food and beverage, advanced manufacturing, and e-commerce and retail. Leveraging patented material science and AI algorithms, Soft Robotics designs and builds automation solutions and soft robotic gripping systems that can grasp and manipulate items with the same dexterity as the human hand.

But Soft Robotics had a problem: “We had a last-minute issue with an encoder on a system we’d built specifically for Pack Expo,” said Craig DeMello. “The day before the show, we had to replace that encoder. We needed a specific count – a very specific encoder.”

Craig reviewed the list of exhibitors and found Encoder Products Company (EPC), an encoder manufacturer based out of a 100,00 square foot, vertically-integrated manufacturing facility in Sagle, Idaho. He visited our booth and said, “Our show demo is down, and we need an encoder to get it back up and running.”

He showed the defective encoder to Tracey Howard, Global Marketing Manager for EPC, and asked, “I’m guessing the answer is no, but I don’t suppose you have anything that would work?”

Fortunately, EPC could help.

Soft Robotics's original encoder (not an EPC unit). The shaft snapped off the day before Pack Expo was due to open, but EPC was able to configure and install a replacement for them.

The Problem

The demo has side-by-side conveyors that run while a Soft Robotics gripper on an ABB FlexPicker quickly executes pick-and-place tasks from above (see video, above). The shaft on the encoder on the gearmotor driving the demo’s front conveyor had snapped off.

“The demo uses the FlexPicker and ABB’s picking software. The encoder in question is on the belt from which the robot picks items, and the robot must keep track of each object – from the time the camera sees the object to the time it’s picked," explained Craig.

"It’s imperative that the robot knows where that product is when it goes to pick it – and the system has to be very accurate.”

Summary of encoder requirements for this application:

  • Shaft encoder
  • Heavy-duty
  • Compact enough to fit the tight space
  • Specific resolution
  • Available to install immediately

 

The Solution

Tracey Howard found the solution: the Model 25SP, a Size 25 programmable shaft encoder.

“Craig showed me the defective encoder and told me what specs they were looking for. I cross-referenced it on the fly, and the programmable Model 25SP was the obvious solution,” explained Tracey.

The Model 25SP is a programmable Size 25 encoder specifically designed for the challenges of an industrial environment.  Contained within the rugged, industrial housing is an advanced set of electronics that allow the encoder to be programmed to exact application needs. Using EPC’s optional programming module, users can:

  • Select from 6 different output types
  • Choose from 32 different waveforms
  • Program any resolution from 1 to 65,536 CPR – that’s 262,144 counts using 4x quadrature counting.

These programming features allow a single encoder to be configured for multiple applications, enabling one encoder to replace many different part numbers, providing cost savings on inventory and down-time replacement.

The Model 25SP Accu-CoderPro® comes standard with dual bearings rated 80lbs axial or radial, and can be specified with up to IP67 sealing. Some configurations are even in stock and ready to ship. So even if we can’t hand you the encoder to you when you need it, we can ship it out right away.

“It was really nice of Tracey to help us out. His team was able to setup the counts and wiring on the new encoder for us very easily. In fact, all we had to do was change the mounting bore – that was it," said Craig.

"We had it installed and our machine up and running in just a few hours. And we’ve ordered a couple more Model 25SPs to have on-hand, since they’re so versatile.”

“We’re known for our fast delivery,” says Tracey, “but this was a record, even for us.”
