Abstract:
A portable roof panel structure assembly mechanism (100) that may be transported to a construction site and that is used to automatically assemble roof panel structures at the site. The assembly mechanism includes a purlin feeder (102), subpurlin clamping mechanisms (106) and feeders (104), and a diaphragm feeder (108). The purlin feeder (102) lifts a purlin into position, and advances the purlin into an assembly station (110). The subpurlin feeders (104) insert a subpurlin into each of a plurality of subpurlin clamping mechanisms, and the clamping mechanisms advance into the assembly station (110) and hold the subpurlins against the section of the purlin that has been advanced. The diaphragm feeder (108) places a diaphragm onto the subpurlins and the purlin at the assembly station (110). The components are attached by automatic nailers.
