Definitions
- the invention relates to an electrostatic Print Help.
- Electrostatic printing aids to support the Transitions from printing inks are in a variety of ways Embodiments known. Be such printing aids used in printing inks, which is a flammable Solvent are to avoid Fires and explosions to take measures that an ignition of the resulting mixture of Prevent solvent with air. In such a explosive environment is subject to the Electrostatic printing assistance special Safety precautions.
- a well-known generic, so-called intrinsically safe electrostatic printing aid (US-PS 4,360,850) according to the preamble of claim 1 achieves the required safety through the Monitoring the ohmic conductivity of one of the High voltage generator connected impedance. If this conductivity exceeds a given value Limit, the output voltage of the High voltage generator turned off and thus his Output line limited to zero. It means that for safety in potentially explosive areas a consumer connected to the generator a predetermined minimum resistance not may fall below.
- the invention is therefore based on the object an electrostatic printing aid according to the Generic term of main claim for use in a potentially explosive environment easier in To design training and more effectively in the company, without this would endanger the security and without security and functionality of the in wide ranges scattering electrical Conductivity of the connected to the printing aid Depend on the consumer.
- the Voltage transfer device as simple as possible can be configured, for example as Slip ring brush, as a contact roller or spring or electrically conductive ball bearings, without that in the hazardous area guided electric Charge, e.g. in the form of electrical sparks regardless of the ohmic conductivity of the Coating of the impression roller an ignition of solvent-containing air allows. So it has to be unlike the prior art not complicated and elaborately encapsulated Voltage transfer devices be present. Rather, all are direct Charge transfer devices possible, as they Prior art so far outside the Hazardous area already in use Find. Also, none are the functionality impairing restrictions on the electrical conductivity of a connected Consumer.
- the high voltage generator with adjustable or not adjustable, but in any case maximum electrical output power points in this case expedient embodiment a voltage limitation for the maximum voltage and / or one Current limit for the maximum current.
- a voltage limitation for the maximum voltage and / or one Current limit for the maximum current are particularly expedient embodiment.
- the Safety is given even if one or two independent errors in the Voltage limiting device and / or the Current limiting device should occur.
- the high voltage generator 3 has a Voltage device 33 for generating a adjustable high voltage on, at one Connection connected in series three Current limiting devices 34 are arranged. Behind this series circuit of Current limiting devices 34 is the Parallel connection of three voltage limiters 35 for the total of 36 designated high voltage to the electrical output terminals 31, 32 of the High voltage device 3 is provided. With this each triple redundant wiring is the Output power of the high voltage 36 to a Maximum value limited.
