A unit, and method of use, for optical inspection of preforms. The unit has a tool (1, figure 1) for receiving the preforms (2, figure 1). Multiple carrier units (3, figure 1) attached to conveyors 7 receive the preforms from the tool, and pass through an optical inspection unit 6. The optical inspection unit moves transversely across the conveyors. In one embodiment, a first and second group of preforms are ejected from the carriers following inspection. A chute (25, figure 11) may be positioned under the conveyors, at the end furthest from the tool, to receive ejected preforms. The conveyors may be linear and parallel. The carrier units may be grippers and height adjustable. The unit may have a monitoring device, such as a sevomotor, encoder (27-30, figure 15), or detector next to the conveyor (31-34, figure 16), to track the position of each carrier. |
