The system utilizes a vacuum end of arm tool that picks the plastic parts and places them in totes. Once placed into totes the robot picks a label and places that on the top rim of the tote. The tote is then ejected out from the station via a sublevel conveyor and the operator is then responsible for placing the label on the tote.

The system has powered conveyors to bring in totes in the center and gravity conveyors to eject full totes. There are right-hand and left-hand parts (mirrors of each other), in order to assist the operator, the output conveyors are separated to help prevent mix-ups of left/right-hand parts. While the cell was originally designed as a collaborative cell, the speed limitations were considerable with everything the client was wanting the cell to do. We
added some guarding and light curtains to allow the cell to run in non-collaborative mode.

Unfortunately, running a collaborative robot in a non-collaborative mode creates significant safety issues and concerns when attempting to meet industry standard safety standards such as RIA. There are various ways to allow this, including safety area scanners, light curtains/fencing, and radar scanners. Collaborative robots are often sold through distributors who don’t understand the safety impacts of integrating a collaborative robot in your facility. They expect you to understand all the requirements and take all the risks.

Come talk to us about your “collaborative” application and get a real perspective on what that means. To see how MJ Engineering can help you, please contact us today!

While the robot is working on the current pallet the operator can be preparing the next pallet. Once all bottles/layers have been completed the robot will pull the next pallet into position and the process starts anew.

The 2nd cell is further down the line. The filled bottles come to the straw insertion station where the straws are pushed into the bottlenecks. MJ has a bowl feeder that presents straws 1 by 1 to a rotation table and where collaborative robots pick the straws off of the rotating table and move them into the funnel that aligns the straw with the bottle. Once the straw is dropped we have a pusher that comes down from above and pushes the straw into its locked position and then the bottles are moved out.

This cell features a lot of moving parts. There are multiple 3D printed parts used for all kinds of things of all kinds of different complexities. The dual mirroring collaborative robots feature 3D printed gripper fingers which help grab the straws. The funnels and the centering devices are also 3D printed. The centering device helps us center the bottles and the straw at the same time. Finally, the pushers are also 3D printed and are responsible for setting the straw into the bottle.

Do you have a project that would require complex parts or complex design? We can handle it. Robotic assembly and palletizing are two of the many areas we can help. Contact us today and let us see if we can help you.

MJ proposed a Fanuc SR-6iA robot to perform a high-speed robotic pack out. The robot featured a gripper end of arm tool to pick up the vials 4 at a time. The vials come to the robot from a bowl feeder which feeds them down a track system that allows the vials to be picked up from the same spot each time. The robot then runs the parts through a machined comb and that straightens the vials up so they could be put in the tray. A conveyor brings the tray around to the operator for packing and shipping.

The robot is able to move an estimated 45,000 vials on a 6.5-hour-long shift. The operator loads the bowl feeder with vials and places empty trays on the conveyor. The high-speed robotic pack out cell comes with a Cognex In-Sight 2000 Vision System to make sure the labels on the vials are placed correctly. The vision system uses a colored ring light to locate the label and verify the orientation.

The cell operates so efficiently that with current production rates the customer only needs to run the cell 3-4 hours a day rather than 3-4 operators 5 days a week.
