A painting target surface of a resin bumper is painted by discharging a paint mist from a spray gun toward the painting target surface with a charged conductor arranged in contact with an opposite side to the painting target surface. The paint mist is uncharged or is charged with electric charges having an opposite polarity to that of the conductor and at a potential having a lower absolute value than that of the conductor.

The second paint robot includes a second robot base and a second robot arm operably mounted on the second robot base. When a virtual plane extending in a vertical direction and along a direction of relative movement between an object to be painted and the paint unit is defined as a reference plane, a distance between the first robot base and the reference plane is set to be shorter than a distance between the second robot base and the reference plane. A passage range allowing passage of the second robot arm is provided under the first robot base.

Paint system and paint method

A rotary atomization head is provided, which prevents discharged threads of a coating material from making contact with each other and from being unified. A rotary headincludes: a diffusion surfaceto diffuse the coating material toward an outer edge partby centrifugal force; and a plurality of groovesformed on the outer edge part. The plurality of groovesextends in a radial direction. The adjacent grooveshave different depths. The grooveshave the same width.

Rotary atomization head and coating device

A coating device includes a rotary head, a power supply part that applies a voltage to the rotary head, and a control part that controls the power supply part. The rotary head is configured so that a coating material is electrostatically atomized. The control part is configured so as to calculate a discharge current based on a total current flowing from the power supply part to the rotary head and a leak current, and control the power supply part based on the discharge current.

Coating device

A coating device is equipped with a rotary head, a drive unit, and an electric power supply unit. The rotary head is configured to be supplied with a coating material. The rotary head includes a diffusion surface that is configured such that the coating material is diffused toward an outer edge portion of the diffusion surface by a centrifugal force, and a plurality of groove portions that are included in the outer edge portion. The rotary head is configured to discharge a threadlike coating material from the groove portions. Also, the coating device is configured such that a diameter of the threadlike coating material is set equal to or larger than 0.03 mm and equal to or smaller than 0.1 mm and that the threadlike coating material is electrostatically atomized.

An electrostatic atomizing coating apparatus and method incorporate a rotary head having a base portion, an open end and a plurality of grooves formed radially on an inner peripheral surface of the open end, an inside diameter of the rotary head increasing from the base portion toward the open end, and a motor configured to rotate the rotary head to discharge a thread-shaped paint. A voltage is applied to the rotary head so as to form an electrostatic field between the open end of the rotary head and an earthed coating target and to electrostatically atomize the thread-shaped paint discharged from the open end. Voltage output from the generator is controlled so as to adjust an intensity of the electrostatic field and to control a particle diameter of the electrostatically atomized thread-shaped paint.

Electrostatic atomizing coating apparatus and coating method

A paint supply method supplies a paint into a paint cartridge by using a filling valve that has: a paint supply channel that is linkable in communication with a supply portion provided for supplying the paint into the paint cartridge; a branch channel that branches from the paint supply channel near a site of linkage in communication between the supply portion and the paint supply channel; and a trigger valve as an open-close valve of the paint supply channel which is disposed in the paint supply channel upstream of the site of linkage in communication. After a filling liquid is filled into the branch channel, the trigger valve (open-close valve) is opened, and the paint is supplied into the paint cartridge via the paint supply channel.

Method of supplying paint to a paint cartridge

A paint filling apparatus has a plurality of header portions, and one common manifold portion that is capable of supplying a cleaning liquid to each header portion. One side of each header portion is attachable to and detachable from a paint cartridge, and another side of each header portion is attachable to and detachable from the common manifold portion. Each header portion has a paint supply channel for filling a paint into the paint cartridge. The paint supply channel of each header portion is constructed of a piping member and a paint channel. An end portion of each header portion is linkable in communication with the inside of the paint cartridge, and another end portion thereof is linked in communication with a corresponding one of paint tanks that are provided separately for each of the paint colors. An intermediate portion of each paint supply channel is provided with a paint valve that controls the open-closed state of the upstream side of the paint supply channel.

An electrostatic atomizerhas a removably attachable canister. Once a paint baghoused in the canisterexhausts, it is replaced by a new canister. Paint in a paint bagis driven out by a mono pumplocated in a pump segmentof the electrostatic atomizer. The mono pumphas a helical shaftinside a paint feed tube. The mono pumpis driven by a servomotor via an insulating drive shaft. Paint in the paint bagis drawn up when the helical shaftrotates, and it is delivered to a bell cupthrough the feed tube. Quantity of paint atomized by the bell cupand interruption of the atomization are controlled by controlling the rotation of the mono pump
