Definitions
- the invention relates to a device for electrostatically charging a multilayer strand according to the preamble of claims 1, 19, 20, 21 and 22nd
- a disadvantage of this electrostatic charge is the low effectiveness of the same on the strand, so that it was necessary to use other devices, for.
- DE 31 17 419 C2 describes a method for electrostatically charging a multilayer strand. After the webs have been brought together to form a strand after a pair of press rolls, the strand is charged by means of contactless electrodes.
- DE 27 54 179 C2 discloses a method for electrostatically charging a multi-layer strand, wherein edge regions of each layer are charged individually by means of rollers.
- the invention has for its object to provide a device for electrostatically charging a multi-layer strand.
- the advantages that can be achieved with the invention consist in particular in that the charging of the strand takes place so sustainably that further devices for preventing or reducing the formation of corners can be dispensed with.
- As a device for charging the strand z. B. uses an existing and required for the operation of the folder pair of rollers, which is modified in its design with regard to the transmission of a voltage. The voltage required to charge the strand is reduced in its amount compared to a voltage required in the prior art.
- Fig. 1 is a schematic representation of a
- FIG. 2 shows a longitudinal section through a roller according to the invention of a pair of rollers according to FIG. 1;
- FIG. 3 shows a representation analogous to FIG. 2, but with a second embodiment variant
- Fig. 4 is an illustration analogous to Fig. 2, but with a third embodiment.
- a plurality of paper webs e.g. B. in a Zy li nder fa Izrios 2 of a folder of a rotary printing machine are a Lzanfa Izei nri device 3 with a Trichte rfa Izwa Izenpaa r 4 and two pairs of rollers, z. B. pairs of pull rollers 6; 7 arranged.
- the cylinder alzcuba 2 has a knife cylinder 8 and a collecting cylinder 9 working against the cylinder 8, which in turn interacts with a jaw cylinder 11.
- the cross-folded printed products there are by means of a transport device, for. B. a belt conveyor, another processing station.
- Cylinder fold group 2 arranged pulling roller pair 7 each consist of a first side roller 13 mounted as a roller 13 and a roller 13 mounted on the side side if mounted, which can be mounted on a swivel arm or bearing part 14, as a second loading element. Between the two rollers 13; 16 is the current strand 1 out.
- both rollers 13; 16 from a cylindrical or height-shaped roller body, a metal body 17, which has a jacket 18 made of a limited conductive, elastic covering, eg. B. rubber with a hardness of about 85 ° Shore.
- the metal body 17 is connected at both ends via hubs 19 - only one end shown - to the shaft journal 21 in a rotationally fixed manner.
- the hubs 19 are via ball bearings 22 in the bearing part 14 attached electrically insulated. Isolation exists e.g. B. each arranged between a pivot arm or bearing part 14 and ball bearing 22 Iso lier material sleeve 23 z. B. made of hard tissue, which has a radial bore 24 for receiving a cable feed 26.
- the cable feed 26 takes a feed line, for. B. a cable 27, which is pressed by means of a spring-loaded contact piece 28 for the purpose of energy transfer via an intermediate ring 25 against the ball bearing 22.
- the shaft journal 21 is non-rotatably connected with its end remote from the roller to an annular flange 29, which in turn is connected to a drive shaft 32 in a rotationally fixed manner via an insulating material piece 31.
- rollers 13, 16 can thus be driven separately. Furthermore, a first roller 13 of the pair of drawing rollers 7 with a negative pole of a non-direct current source of approximately five kilovolts, e.g. B. a high-voltage direct current generator, in connection and a second roller 16 of the pair of drawing rollers 7 is connected to a positive pole of the direct current source.
- a non-direct current source of approximately five kilovolts
- B. a high-voltage direct current generator e.g. a high-voltage direct current generator
- the strand 1 preferably consists of paper webs, which are weakly magnetized and have high resistance.
- a metal contact ring 42 is arranged on the end face, the inner circumference of which is connected in an electrically conductive manner to the shaft journal 43 and the periphery thereof is connected to the middle electrically conductive layer 39.
- This can e.g. B. happen that the contact ring 42 at its periphery has a concentric to the metal body 36, mante if örmi ge contact f surface 44, which in turn carries on its end face, annularly arranged, spaced-apart contact tips 46, which with the material of the middle , electrically highly conductive layer 39 are connected.
- the shaft journals 43 - only one shown - are supported in the bearing part 14 in bearings 47, which in turn are surrounded by insulating material 48.
- a contact is made with the contact surface 44 if the eye 49 is insulated against the bearing part 14 and is pressed against the contact surface 44 in a spring-loaded manner.
- the visual body 49 is, as in the first exemplary embodiment, in each case in connection with a cable feed 26 and a cable 27.
- rollers 51 acting as charge electrodes; 52 each from existing, fixed to the frame in insulating material 48 journal 53 with a roller body or metal body 36.
- the metal body 36 is with an electrically highly conductive layer 39, z. B. provided a steel jacket over which an electrically limited conductive outer layer 40 is arranged.
- a bearing 47 is arranged on both sides between the journal 53 and the steel jacket.
- a supply of electrical energy to the rollers 51; 52 takes place via a cable 27, which with the journal 53, z. B. the outside 54 of the journal 53 is in an electrically conductive connection.
- the jacket 39, 40 firmly on the metal body 36 and to isolate and pivot the pins 53 in the ten ten te 11 fixed bearing part 14.
- the cable 27 would have to be by means of a slip ring be connected to the outside 54 of the journal 53.
- the transmission of the electrical energy to the strand 1 can also be carried out by means of conductive brushes arranged on both sides of the material webs of the strand 1, e.g. B. Carbon brushes are required.
- Such sandwich rollers are made, for. B. from a rotatably mounted shaft, which receives a number of non-rotatably arranged disks on the shaft in the axial direction.
- Such a sandwich roller can be adjustable as a single roller or in pairs opposite one another against a strand 1, e.g. B. as a pair of pull rollers.
- both sand rolls When used in pairs, both sand rolls should be like this be arranged so that a metal disc of the first roller is opposite a coated disc of the second roller and vice versa. Each roller in the pair of rollers has a different polarity.
