Definitions
- the invention relates to a Device for electrostatically charging the two Outside of at least one material web with charges opposite polarity, before processing the at least one web of material, this through the gap of a pair parallel to each other and with a small distance mutually arranged rollers is guided.
- Such a device for Electrostatic charging is known (DE-31 17 419 A1).
- several material webs become one strand merged and only the two outer sides by means of one designed as a corona charging electrode
- the invention is based on the object a Propose device by means of which a more targeted Charging with better efficiency is possible.
- the roller can be charged via the surface by means of a so-called contact roller (DE-38 23 739 A1), via brushes known per se, one Slip contact or a corona charging electrode respectively.
- the device according to the invention the charging by device formed from the pair of rollers from the inside performed, each roller over a steel jacket a limited electrically conductive (so-called semiconducting) covering and - for electrical Charging the limited conductive surface - the Steel jacket of each roller to a positive or negative High voltage source can be connected.
- the device according to the invention is because of the supply of Tension from the inside, especially afterwards Installation in existing systems for processing Material webs, preferably made of plastic or paper possible with a high voltage source of 3 to 7 kV.
- the axis or shaft of the invention is expedient Roller electrically connected to the steel jacket and electrically isolated from the machine frame for the roller.
- the limited conductive covering becomes the electrical high voltage to the axis or shaft placed, which has a connection for this purpose.
- This can either be a fixed connection to the axis or as one to be placed on the face of the shaft Thrust bearing be formed.
- the roller has the purpose of Isolation from the machine frame under the highly conductive steel jacket as well as on both of them An electrical insulator on and to the front electrical charging of the limited conductive covering High voltage of the high voltage source over a direction extending essentially parallel to the roller Corona charging electrode applied.
- Such The roller can also be used as an impression roller in the gravure printing process Find.
- Each of the two rollers 5 according to FIG. 1 has one fixed axis 6 in the first embodiment according to Fig. 1 and a steel jacket 7, on the total designated 8, limited conductive coating as Surface is arranged, which is electrically chargeable is. Between the axis 6 and the steel jacket 7 is a provided with a total of 9 designated ball bearings. Between the two arranged parallel to each other There is a gap 50 between the rollers.
- the axis of the roller 5 is 10 in total designated machine stand in a total of 11 designated electrical insulation stored.
- the Distances 12 and 13 are sufficient to discharge or To prevent voltage flashovers.
- the end face 14 of the axis 6 is with a total 15 designated generator and a measuring device 16 with connected to a terminal 17, which to the terminal 17 leading line is grounded via a resistor 18.
- the machine stand 10 is, as schematically with 19 designated, also grounded.
- the shaft 20 from the machine stand 10 is either via an electrically insulating ball bearing 22 or separate insulation 11 connected. It is also possible, to use a normal, electrically conductive ball bearing and between this and the machine stand 10 one to provide electrically insulating sleeve 11.
- the further, third embodiment according to FIG. 3 has also two rollers to form a gap, from but only one for the sake of a better overview Roll up like those in Figs. 1 and 2 are described. It is also concentric to Wave 6 of the roller 5 next to this on one end face 112 a first designated 113 overall Recording device as a magnetizable core with a Secondary coil 114 and a second secondary coil 115 each arranged concentrically to the shaft 6.
- the cradle 116 is. by means of a Pin 119, which in a with respect to the machine frame fixed anchoring 120 engages with respect to shaft 6 rotatable and has an overall on the inside 121 designated ball bearing, so that this is can rotate, but the magnetizable core due to the Pin 119 and the anchor 120 with respect to the first Recording device 113 can be held non-rotatably.
- a rectifier circuit 122 On the secondary side of the first receiving device 113 is also a rectifier circuit 122 and a Smoothing circuit 123 provided with its output is connected to the limited conductive coating 8.
- the electrical connection 2 of the primary coil 117 is grounded, whereas the electrical connection 1 to one AC voltage generator can be connected.
- the two electrical connections 3 and 4 of the second primary coil 118 are connected to the inputs of a control circuit connectable, which is the size of the output voltage and / or their frequency - in a manner known per se can change.
- the secondary coil 114 is grounded on one side. The same applies to the second secondary coil 115. Both Secondary coils 114, 115 are connected in parallel. Both Coil is first the rectifier circuit 122 for Rectifying the AC downstream. Behind the Rectifier circuit 122 is smoothing circuit 123, e.g. in the form of an LC filter, as is known per se, arranged. The output of the smoothing circuit 123 is with the limited conductive coating 8 of the roller 5 connected.
- the secondary coil 114 against the Primary coil 117 moves. Over the air gap between the two magnetizable cores of the holding device 113 and 116 can therefore the AC voltage of the primary coil 117 induce a secondary voltage in the secondary coil 114, which are rectified via the rectifier circuit 122 and the smoothing circuit 123 directly smoothes that limited conductive coating 8 is supplied.
- the induced voltage of the secondary coil 114 is determined by the second - secondary coil 115 removed and on the second Primary coil 118 in the opposite sense induced with their electrical connections 3 and 4 to one Control circuit is connectable, which the Can control AC voltage source such that at the limited conductive coating 8 of the roller 5 always the same DC voltage is present.
- the embodiment according to FIG. 4 differs from the previous statements in that the shaft or Axis 6 or 20 from the machine frame 10 directly through a electrical insulator layer 40 under the steel jacket 7 of the Roller 5 is arranged. It also extends electrical insulator on the two end faces 41 as frontal insulator layer 42, which is in radial Direction at least up to the axis, shaft 6 or 20 concentric layer 40 extends. she can but also extend to the outer edge.
- a high voltage source 43 is provided, the Exit with a total of 44 Corona charging electrode is connected via a short axial area, substantially parallel to the Shaft or axis 6, 20 extends in the axial direction and the limited conductive coating 8 is opposite.
- the grounded roller core 45 one is created Charge that on the entire surface is evenly distributed so that the limited conductive Covering 8 can serve to charge the material web.
- the roller can also be used as Imprinter in a gravure printing plant to be trained with it to form the electrostatic pressure support.
