摘要： 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 head 1 includes: a diffusion surface 122 to diffuse the coating material toward an outer edge part 123 by centrifugal force; and a plurality of grooves 124 formed on the outer edge part 123. The plurality of grooves 124 extends in a radial direction. The adjacent grooves 124 have different depths. The grooves 124 have the same width.

摘要： 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.

摘要： 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.

摘要： A plurality of painting zones is connected in series by a plurality of air exhaust ducts so as to allow air to flow through the painting zones. A paint mist in air having passed through a painting chamber of each painting zone is removed by a dry filter. Feedback control is performed on the temperature and the humidity of air in a second painting zone other than a third painting zone to which conditioned air from an air conditioner is supplied. Thus, it is possible to appropriately adjust the temperature and the humidity of each painting zone and avoid degradation of painting quality in each painting zone, while achieving downsizing of the entire system by not providing a recycling air conditioner on the route of an air flow passage.

摘要： An electrical color control film includes: an underlying layer located on a metal plate; a first transparent conductive layer located on the underlying layer; an electrochromic layer located on the first transparent conductive layer; and a second transparent conductive layer located on the EC layer. The EC layer is configured in such a manner that color of the EC layer is controlled by electricity.

摘要： A painting system includes painting unit including a first painting robot and a second painting robot, a cartridge carrier, and a cleaning tank. The painting robots each include a robot arm including a painting machine. The cartridge carrier includes a cartridge grip part. A first region is a region where a movable region of the painting machine of the first painting robot overlaps with a movable region of the cartridge grip part. A second region is a region where the movable region of the painting machine of the second painting robot overlaps with the movable region of the cartridge grip part. The cleaning tank is provided in a position including at least a part of the first region and at least a part of the second region.

摘要： A paint system includes a paint unit having a first paint robot and a second paint robot. The first paint robot includes a first robot base and a first robot arm operably mounted on the first robot base. 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.
