Abstract: A hose mounting arrangement for an adhesive-dispensing robot of the type having a mobile robot arm which applies high viscosity adhesive to a workpiece on an assembly line via a dispenser nozzle on the end of the robot arm. A rigid hose-supporting boom is mounted in cantilever fashion on a rear portion of the robot, such that the forward end of the boom extends to a point proximate and above the robot arm wrist. The boom either carries or forms a rigid adhesive supply conduit. Adhesive from the conduit is carried to the dispenser nozzle on the end of the robot arm by a short length of semi-rigid supply hose connected at one end to the top surface of the forward end of the boom, and extending up, out and around in the form of an inverted loop or bail to the dispenser nozzle.

Abstract: A mastic applicator system for delivering a mastic material to a surface in a precisely controlled manner. The system includes a mastic pump, a regulator receiving the mastic from the pump, a nozzle, and a jacketed hose assembly interconnecting the regulator output and the nozzle input. The hose assembly includes an end block having a flat sealing surface, and the end block and the body of the nozzle are fixedly secured together with the sealing surface on the end block in flush sealing contiguous relation to a flat sealing surface on the nozzle body so that a mastic passage and water passages in the end block may respectively sealingly communicate with a mastic passage and water passages in the nozzle body at the sealing surfaces. The mastic passage from the hose assembly to the nozzle outlet is thus totally internal and totally insulated so as to preclude the formation of cold plugs of mastic material during system shut down.
