Abstract

A vibratory conveyor and method of making the conveyor having a frame to which a locator sheet having accurately punched and shaped locator holes for locating spring mounts fixed to the frame. Each mount preferably is a plug having corners which engage notches of one of the holes to accurately locate the plug. Each hole also has a portion which extends beyond the periphery of the plug to expose the frame so that the plug can be welded to the frame. After welding, a protective washer is slipped over each plug and welded to the plug and sheet. When located and fixed in this manner, each mount is located relative to one end of the conveyor, angularly located, and horizontally located. The sheet or another locator sheet can also have other holes to locate other conveyor components such as cross tubes, braces, and the conveyor drive. Each sheet preferably is constructed of corrosion resistant cladding for enabling a less corrosion resistant material to be used for the frame. The conveyor pan is constructed from a blank that is sheared and punched to unitarily form locators that locate spring mounts. In one pan embodiment, the locator is the mount which comprises a tab punched from the pan, bent to the desired angle, and fixed to the pan preferably by welding. In another embodiment, the locators are dimples or holes in the pan for locating mounts that preferably are plugs welded to the pan after being located.
