A method for sorting and/or orienting caps using an automated capping line can comprise providing a single cap to a cap-receiving cavity defined in a body of a puck. In various embodiments, the body can be vibrated to settle and/or orient the cap to a properly oriented position within the cap-receiving cavity. In at least one embodiment, the vibrating can include applying horizontal vibration and/or vertical vibration to the body. As a result, the properly oriented caps can be conveyed to a capping machine configured to apply each cap to a cap-receiving portion of a container.
