CUSTOMER DIRECTIVE

The customer’s automotive dashboard parts were very irregular and changed periodically with new products. In order to accommodate a wide range of parts, an overhead rail conveyor with a simple two bolt connection was developed so that different tooling could be attached to the conveyor. The serpentine path of the conveyor through the oven was designed to accommodate the customers available floor space, existing equipment, and building columns.

DESCRIPTION

DTI-1480 is an indexing overhead conveyor oven. Parts are loaded and unloaded on the conveyor manually and the number of parts conveyed into and out of the oven during each index is set on the HMI depending on the customers process requirements. Likewise, the index time is also set on the HMI for the desired amount of heating time. Heating is accomplished with electrically heated forced air convection. The part is irregular and impermeable so heated air comes from the bottom and both sides of the part for uniform heating. Laser sensors count the number of indexed parts and stop the conveyor in the same spot consistently. The exit end of the oven features a pneumatically actuated automatic insulated door that closes around the conveyor rail and in between the hanging parts to retain as much heat as possible in between indexes. Due to thermal expansion and wear of the conveyor chain, an exhaust vestibule is utilized on the entrance end in lieu of a door to keep heat from escaping into the plant.
