A paint spray nozzle is provided for a paint spray system. The nozzle includes a single-piece body having a conduit portion. The conduit portion includes a first surface defining a first passage that terminates at an orifice along a longitudinal axis and a second surface that defines a second passage along the longitudinal axis. The second passage is fluidly connected to the orifice. The orifice is configured to direct the paint to flow along a flow path through the second passage. The second surface defines an inlet cross-sectional width positioned at the orifice and an outlet cross-sectional width positioned at an outlet. The outlet cross-sectional width is larger than the inlet cross-sectional width, such that the paint that deposits on the second surface is positioned relative to the longitudinal axis to be re-absorbed into the flow path of the paint.

Treatment system (100) for treating workpieces (102), having a treatment region (108) for receiving workpieces (102) to be treated, and a plurality of operating devices (130) for performing one or more operations on the workpieces (102) to be treated.

An applicator and method of use is disclosed for applying coatings and paints to various surfaces. As shown, the sprayer may have an undercarriage frame that supports three-wheels. All three wheels may run parallel with the first wheels and second wheels attached to the sprayer frame via an undercarriage with the third wheel positioned behind and between both the first and second wheels on a separate arm or frame. The width of the sprayer booms may be adjusted. The undercarriage may be folded entirely or only a portion therein. The arm of the third wheel may be folded or telescope, as required by a particular application. A handle, which may be adjustable, may be positioned between the sprayer frame and the undercarriage. Use of the applicator according to the method discussed herein reduces operator fall exposure and increases application efficiency.

The disclosure concerns an applicator for applying a coating agent (e.g. sealing agent) to a component, in particular for sealing or bonding a flanged seam to the motor vehicle body component. The applicator in accordance with the disclosure first has a nozzle for dispensing the coating agent in a specific jet direction onto a component surface of the component to be coated. In addition, the applicator has a nozzle carrier for positioning the nozzle. The nozzle carrier is hollow on at least part of its length to pass the coating agent. Furthermore, the nozzle carrier comprises a plurality of limbs arranged one behind the other and angled relative to each other. The nozzle is arranged on the nozzle carrier, in particular on the distal limb of the nozzle carrier. The disclosure provides that a spacer, which projects from the distal limb in the jet direction and rests on the component surface of the component to be coated in the coating operation, is mounted externally on the nozzle carrier and thereby sets a predetermined application distance between the nozzle and the component surface.

A paint booth assembly includes a paint booth having a pair of side walls and a flood sheet extending between the pair of side walls to separate the paint booth between a spray portion disposed above the flood sheet and a paint recovery portion disposed below the flood sheet. The flood sheet defines at least one flood sheet opening, and a scrubber unit extends down from the flood sheet opening to establish a shared path of fluid communication of a flow of water from the flood sheet and a downdraft of process air from the spray portion to the paint recovery portion. A scrubber pod is disposed within the scrubber unit and defines a plurality of perforations to induce an initial mixing of the paint particles entrained in the downdraft of process air into the flow of water.

Described herein is an atomizer changing system, including a master unit and at least one slave unit, where the master unit has at least the following components: a releasable connecting element, surrounding a center of the master unit, for a nonpositive and positive connection (KS, FS) of the master unit to the slave unit, a coupling plate arranged in the center of the master unit and having a plurality of coupling points for supplying an atomizer that can be connected thereto with substances, energy and/or information, and an adapter for connecting the master unit to a hollow wrist of a coating robot; and where the slave unit has at least the following components: a coupling plate for connecting the slave unit to the master unit and to the atomizer; and a releasable connecting element for connecting the slave unit to the atomizer.

A method for applying a coating product using the drop on demand technology, wherein the coating product is deposited by a robot applicator including a controller and at least one nozzle with sequential opening, commanded by the controller, the method including moving the nozzle of the robot applicator between a starting point and an arrival point, the projections of which, along the ejection axis of the nozzle, on the surface to be coated, define first and second reference points respectively belonging to two edges of the surface to be coated, in order to deposit a series of drops between the two edges, the spacing between the respective centers of two successive drops being adjusted by the controller as a function of the length of the journey between the two reference points and such that the last drop is deposited in a centered manner on the second reference point.

A quality control system for controlling quality of a paint target includes: an individual identification section associating a step control value and a quality control value with identification information for the paint target on the basis of the amount of movement; a state value computing section calculating a state value indicative of a paint state of the paint target on the basis of a history of a temporal change of the step control value; a learning section learning a correlation between the step control value, the state value, and the quality control value using sets of the step control value, the state value, and the quality control value; an input device receiving information on the amount of movement, the step control value, and the quality control value; and a storage device storing a set of the identification information, the step control value, the state value, and the quality control value.

A painting device equipped with a painting head having multiple nozzles that discharge coating material toward an object of painting. The painting device includes a supply passage that supplies the coating material to the painting head, and a return flow passage that returns, to the upstream side of the supply passage. A portion of the coating material supplied to the painting head that was not discharged from the multiple nozzles is possessed by the painting head, wherein the supply passage, the painting head, and the return flow passage constitute a coating material circulation passage. The coating material circulation passage is divided into multiple segments, each of which contains at least one of the multiple circuit component parts arranged in the coating material circulation passage or the painting head, and wherein the coating material circulation passage allows the multiple segments to be cleaned individually.

A system includes an air conditioner in each zone of a painting process line supplying heated air according to temperature/humidity stabilization conditions for a painting process of each zone of a spray booth; a controller transmitting operation information related to the air conditioner including temperatures and humidities of outdoor air flowing into the air conditioner and indoor air inside each zone of the booth and operating the air conditioner when a control value is received; and a server learning operation information history of the air conditioner collected through the air conditioning controller to accumulate the learned data in a database and extracting the control value for each of controllers of the air conditioner according to an initial operation condition of the air conditioner from the learned data in the database to control each of the controllers of the air conditioner for a predetermined time period based on the extracted data.
