Collaborative Pick and Place

MJ Engineering and a plastic injection molding company have worked together to develop a cell using a Fanuc CRX-10L to help the molding company improve its current process. The new cell is a collaborative robot cell that performs pick and place operations.

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.

Depal Cell – Straw Insertion

MJ Engineering has partnered with a commercial cleaning product manufacturer. The result is 2 independent cells. The first is a de-palletizing cell. This particular cell requires an operator who is responsible for putting the pallet of bottles onto a conveyor.Once on the conveyor, the operator walks around and takes off all of the plastic wraps, and uses a foot pedal to move the pallet into the on-deck position. When the robot is ready the pallet is moved into the unloading zone by the conveyor. Once in position, the robot picks the bottles row by row and places them on a smooth top conveyor where they are transferred one by one onto a conveyor that leads to the fill station. When the robot completes the entire layer it rotates the end of the arm tool and picks up the cardboard tier sheet and disposes it down a gravity ramp and moves on to the next layer.

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.

Robotic Pack Out

A pharmaceutical company approached MJ Engineering asking for help automating their pack out process. This company had vials randomly stored in totes that needed to be packed into trays. The trays would then be put into boxes and shipped out. The entire process was done by 1 operator who had to organize the vials into trays.

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.

Custom Designed Robotic Cell for Adhesive Application within the Automotive & Appliance Industry

MJ Engineering custom designed and built a portable robotic cell for the automotive and appliance industries. This robotic cell is used for applying a single part epoxy to both automotive and appliance components. Based off a customer supplied 2D, Auto CAD print, we first created Solidworks 3D models of the cell, ensuring that the design met all of our client’s unique product requirements. We also designed the end of arm tooling (EOAT) which possessed built-in temperature control capabilities.

In addition, MJ Engineering also designed and built the epoxy delivery system, which included a number of unique components and features, such as a high-pressure main valve, flexible tubing, and a high-pressure rotary union and metering valve. The cell meets tight tolerances for placement of the adhesive. The cell size is 48-in wide, 48-in deep and 84-in high.

Once assured that our custom designed robotic cell fulfilled all of our customer’s precise product requirements, we then installed this unit in our client’s facility in Coshocton, Ohio. This robotic cell was ready to start up immediately after installation was complete. We also provided our client with comprehensive hard copy and electronic documentation for this unit.

This portable robotic cell contained multiple controlled heating zones for constant viscosity of epoxy delivery, consistent bead size from tray to tray, and changeable epoxy nozzles for specific applications. This cell also allowed for controlled bead of epoxy in tight tolerance patterns on stamped metal parts, providing a speed and consistency that is not capable with traditional manual procedures.

Our robotic cell additionally allowed for storage and easy retrieval of multiple programs, which helps eliminate set-up time for operators. Our automated robotic cell provided our clients higher quality products in reduced production time.

Custom Designed Robotic Cell for Shot Blasting

A local client approached MJ Engineering to design and install a custom robot cell for the purpose of automatically handling small parts for the purpose of shot blasting one surface in a blast cabinet. The cell incorporates a circular pallet conveyor and a blast cabinet. The shot material and shot process can be modified to allow for different part finish specifications.

The robot uses a custom designed magnetic EOAT (End of Arm Tool) to pick multiple parts from a pallet and present them into a blast cabinet for finishing. The operator loads one of 12 pallets with a tray of unfinished parts then selects the specific processing program from the touch screen operator panel.

The pallets automatically index into and out of the cell as they are processed by the robot and the blast cabinets.
