Assembly Made Simple with help from Air Power, Presto, GCI, and Cleco
In this case study, Air Power builds a custom integrated system that makes Ergonomics, Safety, and Quality simple with a team effort.
Customer
This customer is a supplier in the Truck and Bus industry.
Challenge
The customer needed to outfit a new work cell assembling large metal components. First, the weight of the fully assembled sub-build components exceeded 1000 lbs. requiring a high weight capacity work table. Secondly, the height variation of the operators presented ergonomic issues from shift to shift to ensure each operator performed his necessary tasks at optimum work heights for ergonomics and safety. Thirdly, target torque for each component exceeded the safety threshold for handheld tooling, 69 ft/lbs, and 135 ft/lbs. requiring a torque management solution to be included in the overall work cell build. Lastly, the components needing to be torqued are deemed quality critical, requiring all data for the fasteners to be documented to ensure a proper build.
Air Power Solution
Air Power included the following in our solution; a 2000 lbs. capacity adjustable height pneumatic Presto lift table, a GCI torque reaction arm, and a Cleco MPro 300 controller with right angle NeoTek tool. We were able to meet the high weight by working closely with Presto directly to customize the adjustable height scissor lift table. GCI was able to build a custom torque arm to provide the needed reach and vertical travel while managing up to 240 NM of torque reaction. We were able to mount the torque arm directly to our adjustable height table, allowing the entire work station to adjust to ideal work height for any given operator. All of this wrapped around the brand new Cleco 300 controller with NeoTek right angle tool allowing for a precise fastening solution meeting and exceeding the quality critical parameters required. The Cleco 300 also allows our end-user to monitor, collect, and organize critical data to ensure they every unit out the door is a quality part.
Results
Air Power’s solution addressed all of the problems the customer faced with this assembly process. The Presto Lift table allows the operator to adjust the height of the entire system to eliminate and bending and back strain. The GCI torque arm holds and handles the Cleco right angle NeoTek tool. This eliminates any lifting and hand or wrist injury from handling a torque tool. Lastly, the Cleco mPro 300 controller gave the customer the ability to ensure perfect quality with every assembly.
Counterweight Confusion
This case study was presented by Baltimore Key Account Manager Lorne Rickert.
Challenge
A counterweight was attached to a turntable before the Hydraulic Motor which “keys” the turntable to the frame, located underneath. The counterweight caused the turntable to rotate until it was so far off balance that the Turntable with Counterweight fell off the Frame, coming to a rest about 2’ from a Team Member! This posed a significant safety hazard, as well as, assembly frustration to the onsite engineering team.
Air Power Solution
Air Power utilized an Ingersoll Rand QX Power Tool and Sturtevant Richmont Digital Wrench to positively confirm that all of the tightening’s have been completed before the Counterweight can be installed.
Results
Air Power’s Engineering Team, Michael John and Jesse Bryant, designed a “Lifting Sling Lock” device that will not release the lifting sling for the counterweight until the Tightening’s are complete – a Poke Yoke control to insure safety. This “Lifting Sling Lock” is utilized in conjunction with the I/O output of the Ingersoll Rand QX and the STR Digital Wrench, thus eliminating the safety hazard of a dropped counterweight. The Lifting Sling Lock will only unlock once all tightening have been positively confirmed, removing a safety hazard and improving overall production quality.
Ingersoll Rand – Makes it Easy
One of the main causes of injury in a manufacturing facility is due to lifting heavy objects. In this case study, Air Power helps a customer eliminate the risk of injury with an Ingersoll Rand custom monorail lifting system.
Challenge
A local machinery manufacturer has had issues finding a suitable solution to include as part of their OEM machinery builds. They had a history of using electrical hoists and I beam trolleys which have not been well received by their end-users. The previous offerings by others were hard to maneuver and difficult to position the load for final placement.
Air Power Solution
Air Power proposed an Ingersoll Rand Zimmerman rail system, which are easily adaptable, cost-effective and easy to use. We designed a system for them that included 4 individual monorails with rigid mount hanger kits to increase clearance and ZAW air balancers with pendant controls for load lifting and proper part positioning. The solution allows each of the 4 sides of their machine to be covered from end to end.
Results
The proposed solution provided the necessary benefits including:
- The ZRA1 monorails utilized minimum push/pull forces, allowing ergonomics on the operator and ease of use.
- For future integrations, the individual monorails provide an easily adaptable solution, should the OEM design change over time.
- The aluminum profile ZRA1 provided a reduction in solution weight.
- The ZAW air balancers allow the end-user to position the load close to its final destination then use the “float” of the balancer for final (and exact) placement of the part; further enhancing the user experience.
Ingersoll Rand Ergonomics Reduce Injury Risks
One of the most common workplace injuries reported is muscle strain due to repetitive motion. Manufacturers are seeking ergonomic material handling solutions to reduce the risk of injury for operators. In this case study, Air Power proposed a solution that successfully eliminated the risk of injury for these robotic machining cell operators.
Challenge
This customer had dealt with various injuries due to the operators handling parts of various sizes/weights while loading and unloading parts onto automated infeed/outfeed conveyors on robot machining cells. Hand and finger injuries were commonly reported, as well as various back injuries. The customer required a solution that was safe and easy for operators to use. The solution needed to be located out of the way of forklift traffic and out of the work area of the cell so as not to impede on the operator’s workspace. They needed a device with the ability to grasp multiple sized parts without hassle. This solution also required a system that was low maintenance, durable, with low compressed air usage.
Air Power Solution
Air Power proposed an Ingersoll Rand column mounted with a 10ft reach and articulating arm. This system mounts out of the work cell yet reaches into the work cell to reach the work area for loading and unloading. It includes an integrated 500lb air balancer for lifting/lowering with the ability to adjust both the lifting and lowering speed to dial in the exact application. This device features low rotational inertia for ease of use and improved ergonomics for the operator, low maintenance, low CFM usage per cycle.
This Custom Air Power/Ingersoll Rand Manipulator is made of heavy steel for durability with pistol grip controls and a dummy handle for ease of use and maneuverability. It includes single-hand controls for lifting/lowering of the device & clamping/unclamping of parts, safety interlock that is load sensing to prevent parts from being dropped once elevated off the work surface, V-shaped movable jaws to allow clamping of various sized parts, padded jaws to prevent damage to machined surfaces, and requires little to no maintenance.
