Definitions
- Active discharge electrode to minimize positive and / or negative charges on moving material webs
- the invention relates to an active discharge electrode according to the preamble of the main claim.
- Discharge electrodes are known as passive discharge electrodes in the form of grounded tips or tongues in a variety of embodiments. There are also so-called active discharge electrodes that can be connected to a high-voltage alternating current source. They are used for unloading or removing the positive and / or negative charge on the surface of preferably rapidly moving material webs, such as are present for example in gravure printing.
- Most of these known active discharge electrodes have at least several rows of needle-shaped individual electrodes arranged parallel to one another, which are arranged within a row parallel to one another with a tip at their free end and can be connected to a high-voltage source. At least one earth conductor is arranged along a row of electrodes, preferably parallel to it.
- the invention is based on the object of designing an active discharge electrode in accordance with the preamble of the main claim in such a way that the greatest possible charge is possible with high-speed material webs and with the abovementioned plastics, in which a charge double layer can form.
- the electrode according to the invention there is also the advantage in the event of a network failure that the row of individual electrodes act as passive discharge electrodes, so that at least a minimum of functionality remains Power failure persists.
- This effect does not occur if the connections between the earth conductor and individual electrodes are interchanged, i.e. the earth conductor is attached to the high-voltage alternating current source and the needle-shaped individual electrodes are connected to earth.
- the individual electrodes are applied to a voltage of the high-voltage alternating current source that is symmetrical with respect to the earth.
- each individual electrode is connected to the high-voltage source via an ohmic resistor, this also results in an effective contactor which shows a schematic cross section through an active discharge electrode according to the invention.
- the discharge electrode designated as a whole by 5
- each individual electrode 8 is connected to the via an ohmic resistor 10 - Not shown - High-voltage source can be connected, which is an AC voltage source.
- ground conductors 11 are provided, which are circular in cross section and can be formed, for example, as a wire. These two earth conductors run at right angles to the extent of each individual electrode 8 and parallel to the plane 9, in which the individual electrodes of a row are arranged. Each conductor is surrounded by an electrical insulator 12.
