Automatic Tube Loaders (ATLs) receive electronic components from an input track and load the components into extruded plastic tubes.
The loaders hold a stack of empty tubes, inclined at an angle normally of 30 degrees. Components are metered by a singulator mechanism and slide by gravity into the bottom tube of the stack, one at a time. The components are guided into the tube by a precision machined track. When the tube is full, it is transferred out of the empty tube stack, the next tube in the stack take its place in the loading position, and loading continues.
