Problems solved by technology

One challenge in re-striping the markings is the precision at which the new stripe overlays onto the existing stripe.
While various types of video and mechanical guidance systems are known for use with vehicle mounted line stripers, all systems known to date suffer somewhat in that while attempting to re-stripe over an existing line,

Embodiment Construction

[0013]The present invention simplifies the line striping process making it more accurate, efficient, and / or less labor intensive. According to an embodiment, the invention is an actuated sensing system that controls the position of a spray nozzle of a self-contained striping apparatus. The system comprises a user interface with controls that communicate with multiple sensors and / or a camera which determines the edges of an existing media line or stripe. According to one embodiment, the pressure and / or volume of the flow of media is fixed, however, according to alternative embodiments, the controls also adjust the pressure and / or volume of the flow of media from the discharge nozzle. The sensors and / or camera determine where the previous media stripe was applied to the surface. They communicate with the controls, which use this information to reposition the discharge nozzle, as necessary, in a way that “follows” the previous media stripe so that the newly applied media stripe overlay...

Abstract

Herein is an apparatus for overlaying a media stripe onto a media stripe previously applied to a surface (i.e., “old media strip”). The apparatus includes a mobile frame housing controls and an applicator head having a spray nozzle that applies new media. The applicator head also includes sensors and/or a camera that cast a cone of vision onto a surface. The cone of vision is positioned tangentially to a first edge of the old media stripe. If while operating the apparatus, the applicator head moves and the new media stripe is not overlaid onto the old media stripe, the sensors and/or camera will direct an actuator arm (or similar) to reposition the applicator head and spray nozzle so that the new media stripe is once again sprayed on top of the old media stripe.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates generally to the application of media onto a surface from a device in motion, e.g., a line striper apparatus.[0002]Stripes are applied to roadways, parking lots, warehouse floors and the like for directing the movement and placement of people, things, and vehicles. Every year thousands of miles of roads and countless square miles of parking lots, warehouse floors, airport floors and runways, and athletic fields are re-striped when the existing surface markings fade because of the natural erosion of time and the elements. Safety, traffic flow, and athletic events rely on clearly visible surface markings and boundaries. There is a need to continuously maintain these markings.[0003]One challenge in re-striping the markings is the precision at which the new stripe overlays onto the existing stripe. While various types of video and mechanical guidance systems are known for use with vehicle mounted line stripers, all systems k...
