We finished a large, automated packaging – end of line integration project last year for Closure Systems International. This company produces plastic caps for most all the plastic bottles you drink from. The system MCRI integrated focusses on the areas of case erecting, packing, transporting, and palletizing.

Customer’s Challenge

MCRI’s End of Line Solution for Moving the Caps and Reducing the Footprint

“It was our goal to seek out an integrating partner who would understand our issues and provide us with a turnkey system ” says Floyd Needham, President/CEO of CSI.

1. Flexible and dynamic movement throughout the plant was essential and this couldn’t be accomplished with conveyors, so it was decided that 30 Daifuku SmartCart AGVs would be used to move the cases of caps around to the proper location in the facility. This also made it possible to add a centralized palletizing location. The central palletizing area has 34 pallet locations where ONE FANUC palletizing robot runs on a Gudel rail and picks and places full layers of cases.
2. Caps in a box can cause a centralized mess if boxes aren’t taped properly, so MCRI’s patented, inline robot tape inspection was added to the system to scan for proper tape placement before the cases move to palletizing area.
3. The final space saving technique was using an MCRI robotic random case erector to build 4 different case sizes. These case sizes were not needed/called as often, so it gave the robotic case erector plenty of time to build the cases. This saved the company the space of having 4 different case erecting machines.
4. MCRI implemented our ImpactIQ Industry 4.0 Software technology for system and product tracking. The modules used for this project included Dashboarding, Database Interface, Portable HMI Tablets, and complete Wireless Infrastructure.

System Video – Automated Packaging – End of Line Solution

Watch our system video to see the robots and AGVs in action and then go to Sequence of Operations below to read the full explanation. We teamed with FANUC America to document and video this system.

The Robots & AGVs Used for Automated Packaging

We selected 4 different FANUC robot models to perform different application in this automated packing solution. There are 4 FANUC robots, 30 AGVs, and 2 Clamp Vehicles that round out this end of line solution for handling cases of caps.

FANUC M20iA/35M

The FANUC M20iA/35M, which has now been retired, was used in the case erector cell. This robotic random case erector saved space by erecting 4 cases in one area. The case cartridge held 4 different case dimensions – the robot would pick and erect the case based on the size that was requested. The cases were erected and sent to an inline labeler and then picked up by an AGV to be bagged and filled with caps.

LRMate 200iD/4S

The LRMate is one of the standard robots for the MCRI Inline Tape Inspection Station. These stations can be added to any current conveyor setup to scan tape ends as the case enters the palletizing area. Improperly taped cases can cause unneeded downtime if contents fall out of the case. This is especially import for a case that may contain hundreds of caps.

FANUC M410iC/315

FANUC has the best selection of palletizing robots and their M410 series is specialized for this application. The M410iC/315 was installed on a Gudel Rail that allows for a 7th axis to move to the 34 pallet locations in the centralized palletizing area.

FANUC M410iB/140H

This M410 is a material handling robot installed in the final sequence for the end of line solution. When stacks are brought to the wrapper the M410 places a pallet for the clamp vehicle to place the stack of cases.

Daifuku SmartCart – 100TT Tugger Vehicles (AGV)

The base of the each of the 30 AGVs is a 100TT Tugger from Daifuku SmartCart These have a weight capacity of about two thousand pounds. This allowed MCRI to add a roll conveyor for transferring and picking up cases. The AGVs move around the facility using a path planned for efficient travel and employee movement. The carts move slowly and use area scanners to slow and stop as an object or person moves into the path. As the carts’ battery runs low it finds a battery charging station and parks. The rotation of carts running and charging allows for enough carts moving through the facility 24 hours a day.

Dematic Automatic Guided Clamp Truck Vehicle (AGV)

The 2 clamp vehicles pick up full pallet stacks and move them to the stretch wrapper.

✓ Safety Features

Motion Controls Robotics follows the ANSI/RIA R15.08 for robotic Safety Standard designed to ensure employees and robots work safely together. The AGV safety measures are laid out in the ANSIB56 guidelines. We take full advantage of new safety technologies and innovations as they become available.

Main Safety Features

• This system is complete with safety fencing and needed safety sensors.
• Light curtains prevents operators from entering the robot cells.

Customer Results – Complete Automated Packaging End of Line Solution

The customer was able to reach their new production goals. They saw a drastic reduction in downtime and were able to meet their OEE goal of 97.5 percent efficiency. CSI has seen a 25 percent increase in cap production (approximately 30 million units per month). The completion of the project and first 6 month run of the system gave the company the go ahead to expand their operations in Crawfordsville, IN.

“Having the confidence that we can install new capacity and deliver on time in full for our customers is what you need to invest in a United States plant. If not, you might make the decision to invest elsewhere,” says Floyd Needham, President/CEO of Closure Systems International. “Having the automation and robotics system does give you a level of confidence that you’ll be able to staff that line and deliver a product to your customer on time.”
