Fori recently supplied a module assembly system that included the Fori Flex Rail conveyance system which utilized Rail Guided Carts (RGCs) and a drive-thru module aligner for the assembly and alignment of a rear suspension module.
The module assembly system had a unique set of design constraints. One example was that the floor space available within the plant for the required rear suspension module was limited, requiring a common unload area with an existing assembly line. Due to the oddly shaped footprint available for assembly and the mandated unload area, the end user utilized Fori’s RGC to accommodate their needs for a flexible material handling and assembly system.
The system utilized a standardized Siemens control architecture, including the RGC, traffic control, and aligners. The standardization of Siemens controls was customer requested in order to match their existing controls architecture. In matching the controls architecture between all of the equipment, Fori was able to offer seamless integration into the customer’s assembly plant.
The rear main assembly line was composed of 15 RGCs, seven operators, one automatic drive through alignment machine, and one manual backup alignment system.

Fori supplied a rear module suspension assembly line utilizing Fori Rail Guided Carts (RGC) as a conveyance and assembly method alongside two fully automatic drive-thru module alignment systems.
The assembly line consisted of (22) RGCs, two drive-thru aligners, (16) operators and various torque tools. The product for the rear suspension module varied between all-wheel drive and rear wheel drive vehicle variations. The build pallet on top of each RGC accommodated those variants and manipulated the ride height setting of the five link suspension by manually setting the ride height wheel in the correct position verified by a switch on the pallet.
A drive-thru aligner was also utilized within the system to help streamline the process. A lift and locate unit was located in each drive-thru aligner that would pick the pallet from the RGC and accurately present the suspension assembly for alignment.
Utilizing Fori’s RGCs allowed for a timelier changeover. The RGC system also provided long term flexibility supporting:

Fori retrofitted an existing assembly line to accommodate the integration of a new vehicle platform.
During extensive layout and process reviews, all areas that required rework were identified so a plan could be developed to add field kits which consisted of new portions of assembly line. In order to be flexible and to accommodate the heavy variation in product, a number of robotic torque applications were added each with a common trombone torque tool to be utilized on all module complexity types.
In order to accommodate the new product, two additional aligners were reworked from another customer plant and installed on a new conveyor section of the assembly line.

Fori recently supplied a module assembly line for axle assembly. The production line consisted of a Fori twin strand conveyance system with manual assembly stations, automatic Lateral Run Out (LRO) and automatic end of line robotic vision system for inspection.
The required equipment was met with a few unique challenges and aspects:
Prior to testing the LRO, the hub and rotor must be assembled on a test fixture complete with constant velocity. The joint and hub fasteners are then tightened according to production standard and are able to withstand an axial load of 100 kN. In order to accomplish these items the equipment had to lift the axle from the pallet prior to being secured.
Due to the rotors being unable to be retained flat against the hub, the equipment could not guarantee “non-contamination” that could potentially produce a fault during LRO. In order to correct this the “retry method” of the equipment was to remove the rotor, index to the next rotary present pattern and reinstall the rotor to the hub prior to LRO testing.

Fori recently supplied an assembly system for an american motorcycle manufacturer. The system comprised of manual push pallets on a vertical conveyor system consisting of a main build line and two vertical lift support stands.
Not all projects require high levels of automated equipment in order to meet the end users production requirements. This project is a great example of how Fori took a powered vertical conveyor system and redesigned it to a manual push pallet system based on cycle times and customer budget requirements. The updated design provided the customer increased flexibility for their long term build process. The line was designed in modular sections for future expansion of increased production as required based on customer demand.
The ability to be flexible with the pallet provided the ability to use the vertical conveyor for more than current parts or model changes. Overhead support for tooling was a jib boom that bolted to the floor to remove the assembly to dunnage.

Fori recently provided two high capacity Aerospace AGVs for the automated transport of a mobile robotic drill and fill system.
The two high capacity AGVs (transporting mobile robotic platforms with weights up to 40,000 pounds) have been designed to accommodate projected production. The Fori AGVs will be the primary method of transporting the mobile robots between each of the necessary drilling stations.
The AGVs were developed to increase system automation, flexibility, and remove the traditional monuments that are generally required for automated drilling applications. The design intent was to build a vehicle that was modular and interchangeable. The AGVs were designed to accommodate multiple mobile robots, the software is modular, and simplifies the communication between the Fori AGV and mobile robot.
The Fori AGV is required to locate within +/- 5mm to an existing fuselage transporter. The Fori system utilizes a natural feature and camera based guidance system, which accommodates unexpected location of the transporter. The Fori system overcomes the variability of the fuselage transporters accuracy by measuring the surface of the transporter to generate angular offsets and utilizes a SICK camera and reflector based system for final location. Once positioned, the mobile robot automatically docks to the transporter for power, communication, and pneumatics.
Automated movement is handled through the tethered Siemens Mobil Panel. The operators are able to select drill positions on either the Fori HMI or robot HMI. Once selected the Fori AGV is responsible for safely and accurately lifting and transporting the two mobile robots between 16 different drill positions.

Fori recently provided seven high capacity Aerospace AGVs for the automated transport of tooling for spar assembly, supporting the production of composite wing assemblies.
The seven high capacity AGVs, capable of auto-leveling and synchronized transport of tooling up to 120,000 pounds have been designed to accommodate projected wing production. The Fori AGVs will be the primary method of transporting the tooling and product through the assembly process. Traditional assembly systems rely heavily on overhead crane utilization, the AGV based solution eliminates the reliance on cranes.
The AGVs were developed to support a lean, automated manufacturing methodology. The goal of the project was to automate the entire material handling process for the assembly of the spars. Notably, the load and unload of the autoclaves used for curing the composite wing spars. The loading of the autoclave is completed utilizing a natural feature guidance system, the AGV uses the walls of the autoclave for the guidance in and out, while still maintaining +/- five mm accuracy.
The design intent was to build a vehicle that was modular and interchangeable. The AGV system is required to transport many tools of different lengths and weights. The AGV system needs to be able to accommodate synchronization of up to three AGVs during the lift and transport from assembly stations.
Each of the AGVs is outfitted with four servo based lifters and a laser alignment system which provides measurement feedback to the on-board PLC for the dynamic leveling of the tooling during transport. The system must maintain levelness within +/- 1/8” from each end of the tool.
