How to Find a End Effector in Luther ?

Whether the fabricator’s store is large or small, the Ironworker is the backbone. The Ironworker isn’t a single machine; it is five machines united into an engineering wonder. It has much more versatility than most people would imagine. The five working sections that are involved in the make-up of this machine are a punch, a section shear, a bar shear, a plate shear, and a coper-notcher.

A number of the cheaper ironworkers are constructed to employ a fulcrum where the ram shakes back and forth, building the punch go into the succumb at a small angle. This normally leads to the erosion of the punch and die on the front rims. The higher quality machines integrate a ram which moves in a direct vertical line and utilizes modifiable gibs and guidebooks to insure a constant traveling route.

End Effector Design

When you look for a End of Arm Tooling (EOAT)  that develop a End Effector in Luther, looks for experience and not only pricing.

That devotes more life to the tooling, and allows the punch to penetrate the die right in the middle in order to capitalize on the machine’s total tonnage.

When looking for a design house that designs a End Effector in Luther  don’t look just in Michigan , other States also have great providers.

Robotic System Integration

Summary:

Cabot Microelectronics used two different FactoryFix Experts for Robot System Integration to retrofit an existing Fanuc Robot Palletizing System that had been sitting unused in their facility due to an unsuccessful installation by the original Robot Integrator. Cabot found two qualified companies to do the work on-site at their facility in Aurora, IL by posting the project on www.factoryfix.com.

FactoryFix Experts:

Compass Automation & Elite Automation

Customer Benefits:

Full System Retrofit — went from an unsuccessful installation to fully operational automated system.

Automated Production — Elite Automation programmed the system to run unattended for 3 shifts.

Added Functionality —Elite Automation also modified the system to run an additional part number.

Technologies:

Refurbished Fanuc R-2000 robot with IR vision system

Fanuc ArcMate robot with custom ultra-sonic knife tool

ATI Tool Changer System

Custom designed Piab vacuum gripper End-of-Arm Tooling

Solution:

Compass Automation, Inc worked with Cabot Microelectronics to redesign a 2 robot system to de-palletize large bags of silica powder, cut-open the bags using an automated ultra-sonic knife, and dump the powder into a large hopper. The system had been sitting idle on the customer’s floor for over a year due to a poor execution by the initial Robot Integrator. Cabot used FactoryFix to find local automation companies that had the expertise to retrofit the system and get them back on track. After posting their first project under the End of Arm Tooling Design category, they were connected with Compass who quoted and eventually won the job. Compass designed and built a complicated vacuum gripper that accommodated two different product sizes. The gripper also had to be designed with automated flappers to mimic a human shaking the bag over the hopper to make sure all of the powdered silica got out of the bag. The second robot tool that Compass was hired to design was a custom ultra-sonic knife tool that was mounted on the refurbished Fanuc Arc-Mate 100 robot. This tool was designed for ArcMate robot to cut slits into the silica bag while the R-2000 robot was holding it with the vacuum gripper.

Once the two EOAT’s were built and mounted to the robots, Cabot Microelectronics needed to find another local supplier to come in and program the system (Compass had a scheduling conflict). They posted the project request on FactoryFix and were connected with Elite Automation, an automation company based out of nearby Carol Stream. Although it was a complex system, Elite Automation wrote the program and successfully ran-off the system within two weeks. Elite has since been hired by Cabot Microelectronics several more times for program modifications and upgrades.

This job is among one of my favorites. It’s because the entire project was mine. I started by going out to their facility and seeing their inefficiencies. One cell that they were very excited to revamp was their Silica dump cell. I was able to come up with the initial concept, quote the project for materials and labor, and then do the engineering myself. I did, not only the mechanical design and detailing, but also the electrical and pneumatic schematics. I felt in charge of the whole thing- high risk, but high reward.

A HUGE 6 axis robot (ok, not that huge, I’ve used bigger) but an R2000 robot picks up these paper bags filled with Silica. The end-of-arm-tooling (EOAT) used vacuum suction to hold onto the bag.

It bring it over to a hopper, where a smaller robot uses a knife to cut the bags. The larger robot then flips it’s tooling to dump the Silica into a hopper. Seems pretty simple and for the most part it was. However, the Silica is so densely packed into the bags that even when the bags were cut wide open, the Silica wouldn’t dump. To help the Silica loosen and fall, we stick needles into the bag and blow air through these probes which moves the Silica powder around. We then (for a lack of engineering terms) flap the bag to further empty the Silica. It may sound tedious, but any powder or residue left in the bag is money wasted for the company.

An SMC slide cylinder pushed the air probes through the paper bag, and the fittings attached to the other side provided air to go through to the holes in the probe.

Another part of the project was to add a tool changer to the smaller robot. It was originally just equipped with the knife, but by adding a tool changer with a “Silica break tool” the robot was able to then go into the hopper and break up large clumps of Silica helping the contents of the hopper drain. Imagine a giant potato smasher. (Which is in fact what we ended up often calling the tool.)

I had a lot of fun working with my machinist and builder on this project. I did everything I could to help them succeed, but also knew they had my back on this as well. I understand that that dynamic not all that common in the work place, so I really appreciated it. The install is happening currently and now the programmer is up to bat. The EOAT has a camera and laser to locate the bag. The camera locates the XY location of the bag and the laser the Z (height) location. I can’t wait for the tooling to be fully power, programmed, and running. I really think the customer will be happy with this addition.
