ABSTRACT:
The invention relates to an automatic assembly apparatus for assembling devices from a plurality of parts. The apparatus uses both continuous motion, for assembly, and reciprocal motion, for processing. The apparatus includes a sub-assembly station for assembling sub-assemblies from at least two of the parts and a processing station for processing a third one of the parts. The sub-assemblies and the processed parts are then brought to a main assembly station where they are assembled with the remaining of the parts to form an assembled device. In the embodiment illustrated, the apparatus is used to assemble syringes. At the processing station, the syringe barrels are cleansed and lubricated, and at the sub-assembly station the plunger tips are mounted on the plungers. The sub-assembly and the processed barrels are then brought to a main assembly station where they are assembled with needle arrangements to form an assembled syringe. In the preferred embodiment, the assembly station and the sub-assembly station are made of rotary drums having vertical slots equally spaced around the peripheries thereof to carry the various parts.
