Embodiment Construction

[0033] First refer to figure 1 . A painting installation is generally indicated at 10 , which includes a painting cabin 12 . The painting cabin 12 delimits with a cylindrical bulkhead 14 an inner chamber 16 which is functionally divided into an upper painting area 18 and a separation area 20 arranged below it. A cabin roof 22 is conventionally designed as the lower limit of the air supply chamber with a filter roof, not shown here, through which the air can be fed from above into the painting area 18 and the air can flow through it. The lacquer region flows downwards into the separation region 20 .

[0034] In the separating region 20 there is an electrostatically operating separating device 24 which comprises a plurality of planar separating plates 26 arranged parallel to one another, of which only two bear the reference numerals. Between each two separating plates 26 there is an electrode unit 28 with a corona wire 28 a and a plate electrode or grid electrode 28 b , only ...

Abstract

In a method for electrostatically coating objects, an electrical field is generated between an application device (34) and an object (50) to be coated. At least one corona electrode (42) associated with the application device (34) is connected to ground, and at least one counter electrode (60; 60, 64) associated with the object (50) is connected at least at intervals to a positive potential. In addition, the invention relates to a system for electrostatically coating objects, which comprises an application device (34) for coating material, and an electrical field device (42, 46, 60) having a high-voltage source (46), by means of which an electrical field can be generated between the application device (34) and an object (50) to be coated. The field device (42, 46, 60) comprises at least one corona electrode (42) associated with the application device (34), and at least one counter electrode (60; 60, 64) associated with the object (50), wherein, during the operation of the device (10), the at least one corona electrode (42) is connected to ground, and the at least one counter electrode (60; 60, 64) is connected at least at intervals to a positive potential.

Description

technical field [0001] The invention relates to a method for electrostatically painting an object, in which an electric field is generated between an application device and the object to be painted. [0002] Furthermore, the invention relates to a device for electrostatically painting objects, comprising: [0003] a) Applicators for coating materials; [0004] b) An electric field device with a high voltage source by which an electric field can be generated between the application device and the object to be coated. Background technique [0005] With such methods and application devices known on the market, objects can be painted, for example. [0006] For this purpose, the object to be painted is at ground potential. As the opposite pole, a negative high potential is applied to the application device, for example a rotary atomizing spray device, or an ionization device is assigned to the application device, by means of which the paint droplets or particles are ionized. ...
