Fori Automation recently provided a module assembly and alignment line with limited floor space available. The system is between an existing assembly line & plant wall with the inability to get material to all parts of the assembly line required a unique process.
The minimal footprint available for assembly provided challenges for common 22unload areas within an existing assembly line. The Fori RGCs were utilized to accommodate our customer’s need for a flexible material handling system.
The assembly system included a consolidated kit area. The kit area was specific to loading and hand starting parts followed by an area for torqueing. Due to the foot print constraints the process had to be strategic on how to best utilize the available space. The project also included a fully automatic suspension module aligner & backup semi-automatic aligner.
The utilization of Siemens controls matched the controls architecture for the end user and provided a seamless integration into the assembly plant.
The rear main assembly line was composed of (17) RGCs, (16) operators, (1) automatic drive through suspension module alignment machine & one semi-automatic backup alignment system.
The new RGC assembly line was installed early June of 2018 & was production capable in Fall of 2018.
Large numbers of variations in assemblies matched with high job per hour requirements is challenging. Fori Automation provides solutions to correctly sequence multiple variants to the assembly area. These systems are designed to maximize floor space and can be quickly updated to accommodate variant count changes.
The module assembly project consisted of a lean automated system. The commodities involved are FCOS assembly (both spring & air ride models).
The choice of automated conveyance for this project was the Fori’s rail guided cart (RGC). The customer currently has (4) programs in production utilizing the Fori RGC with a 5th project to be operational in 2020.
The FCOS sequencing & assembly system consisted of (7) RGCs, (4) semi-automatic FCOS assembly cells and (1) upper isolator to upper mount assembly press. This system also included a large sequencing area. This “market place” style area worked directly with the customers manufacturing execution system (MES) to direct the RGC cart to the correct product storage position. Pick lights were activated to assist operators in the selection of the correct variant of spring, shock or air shock as requested by the OEM.
The new RGC assembly line was production capable in September of 2017.
