The present invention relates to a double bell cup installed on an end portion of a painting robot to centrifugally spray paint to an object to be painted, the double bell cup comprising: an outer body having a tapered structure that becomes gradually wider from the top to the bottom, wherein the outer body has an inlet passage formed on the top side thereof, a stagnation passage formed therein to communicate with the inlet passage, and a spray passage formed on the bottom side thereof to communicate with the stagnation passage, and paint is introduced through the inlet passage and retained in the stagnation passage; and an inner body having a tapered structure that becomes gradually wider from the top to the bottom.

This skirt (20) is intended to equip a coating product rotary projector. The skirt (20) has a plurality of air ejection nozzles (40, 42, 44, 46) arranged in said skirt (20) to eject jets of air forming shaping air suitable for shaping the jets of coating product, said air ejection nozzles (40, 42, 44, 46) comprising at least three separate series of nozzles (41, 43, 45, 47) each made up of a plurality of air ejection nozzles (40, 42, 44, 46) fluidly connected to a shared supply chamber, specific to said series of nozzles (41, 43, 45, 47).

A coating apparatus is disclosed for applying an activated coating onto an internal surface of a conduit, the coating being activated by mixing at least a first and a second component. The apparatus includes a high-pressure mix gun for mixing the at least first and second components such that the activated coating is generated. A rotary atomizer is operatively connected to and cooperates with the high pressure mix gun for receiving the activated coating from the high pressure mix gun. The rotary atomizer cooperates with the activated coating such that the activated coating is atomized so that application of the atomized activated coating onto the internal surface of the conduit is permitted.

Example apparatuses and methods are provided for detecting a fault in a painting system. A fluid supply line such as a paint line or isolation line may have an outer wall formed of a material which permits light to be transmitted through the outer wall. First and second optical conduits may be provided, which are configured to transmit an optical signal through the outer wall and receive a reflected optical signal, respectively. An optical sensor may be in communication with the second optical conduit such that the optical sensor is configured to receive the reflected optical signal. A fault in the fluid supply line, e.g., traces of a previous color paint, air bubbles, or other contaminant, may be detected based upon a comparison of the received optical signal with the optical signal transmitted through the first optical conduit.

A rotary atomization type painting device includes an atomization head that supplies paint from a paint supply machine. The atomization head has an outer member that includes a truncated conical body, and an inner member that is disposed inside the outer member. The inner member has an annular protruding part that protrudes toward a large diameter side opening. The paint is lead out from a plurality of lead-out holes of the inner member to a root of the annular protruding part. At a root position in an axial direction, an angle in a lead-out direction of each of the lead-out holes with respect to an axis, and an angle of an inner surface of the annular protruding part with respect to the axis are made equal.

The disclosure relates to an applicator (RZ), in particular a rotary atomizer, for the application of a coating agent, in particular a two-component paint, comprising a first coating agent connection (SL) for feeding a first coating agent, in particular a basic resin of a two-component paint, a first coating agent strand (L1-L4), which extends in the applicator (RZ) from the first coating agent connection (SL) and carries the first coating agent, and a first valve (SLV1), which is arranged in the first coating agent strand (L1-L4) and controls the flow of the first coating agent, wherein the first valve (SLV1) can be controlled by a first control signal. It is proposed that a first pressure-relief valve (SLV1), which is actuated by its own medium, is arranged in the first coating agent strand (L1-L4) and, to avoid a problem being caused by excessive pressure, opens automatically when the pressure upstream of the first pressure-relief valve (SLV1) exceeds a certain maximum pressure.

A method for cleaning a paint spray gun, which comprises a rotating atomization head to apply a coating material while rotating and an outer circumferential tube to cover the exterior of the rotating atomization head, has a cleaning solution application step for applying a cleaning solution to the external face of the outer circumferential tube, and a rotating atomization head rotation step for generating a rotational flow between the rotating atomization head and the outer circumferential tube by rotating the rotating atomization head. The cleaning solution flowing down the external face of the outer circumferential tube applied in the cleaning solution application step penetrates between the rotating atomization head 5 and the outer circumferential tube by way of the rotational flow. Such method uses a small amount of cleaning solution for cleaning external and internal faces of the outer circumferential tube and the external face of a rotating atomization head.

The disclosure relates to an extended-range spray applicator, and methods of making and use thereof, for dosing vaccines and/or probiotics to avian animals at a distance.

Exemplary embodiments of a mister of the current invention comprise a reservoir, a spacer, and a dispenser assembly. A spacer fixedly joins the reservoir to the dispenser assembly a set distance. A liquid stored within the reservoir is configured to exit the reservoir at the valve through the spacer and impinge the dispenser assembly.

The dispenser assembly includes a dispenser and a motor, the motor providing a rotational force for application to the dispenser. The dispenser presents an axis oriented to the liquid stream flow from the reservoir. Upon liquid stream flow impinging the rotating dispenser, the centrifugal force causes the liquid stream flow to spread radially from the dispenser to the air and/or surface in the target area, where it is dispersed outwardly over a target area, atomized or as droplets.
