Abstract
An alignment device for aligning a photo-detector with a target on a conveyor includes a mount for the photo-detector having at least two apertures. Screws are inserted through those apertures into corresponding apertures in a bracket attached to the conveyor. The screws are threadedly secured to one of the mount and bracket and non-threadedly secured to the other of the mount and bracket such that rotation of either of the screws alters the distance between the mount and the bracket. The alteration in distance changes the orientation of the photo-detector. Springs may be mounted between the bracket and the mount.
