    The invention relates to a device for venting a aufzutragenden on a fibrous web coating medium, with at least two mutually parallel venting. Furthermore, the invention relates to a device for coating a fiber web with an application device for applying a coating medium and with a device upstream of the application device for venting the coating medium.
    From WO 2006/128963 A2 a device for removing gas from a coating material is known.
    A method and an apparatus for coating a fiber web with such a ventilation device are described in DE 11 2007 002 171 T5.
    Usually, such a coating device has a deaerator of the type described, for example, in WO 2006/28963 A2, which can be connected to a plurality of units for its supply, such as pumps, pressure sensors, control devices and the like. There may be instances in certain coating devices where the capacity of a breather is insufficient to adequately vent the flow of coating medium supplied to the coating device.
    It is therefore an object of the present invention to provide a device for venting to be applied to a fibrous web coating medium, which is able to remove even larger amounts of gas from the coating medium, the device should have the simplest possible structure ,
    According to the invention this object is achieved by the features mentioned in claim 1.
    By the at least two mutually parallel air vent, the venting capacity of the device according to the invention can be significantly increased. In this case, at least one unit operatively connected to the deaerators serves to supply both deaerators, whereby despite the increase in the deaeration capacity, with the exception of the at least one further deaerator, no additional parts are required. As a result, the venting capacity of the device according to the invention can be increased considerably at a relatively low cost.
    Another advantage of the solution according to the invention is that it must be switched on and off less often that the required for the device lines must have a shorter length and that a simpler automation is possible.
    In a very advantageous development of the invention can be provided that the unit is a feed pump for supplying the coating medium to be applied to the vents. In this way, only one feed pump for supplying the coating medium to be applied is required.
    Additionally or alternatively, it may be provided that the unit is a discharge pump for discharging the coating medium to be applied. In this embodiment, only one discharge pump for the applied to the fiber web coating medium is required, whereby the device according to the invention can be carried out considerably simpler and cheaper.
    In order to save a vacuum pump, a further advantageous embodiment of the invention may be that the unit is a vacuum pump for generating a negative pressure for the deaerator.
    Furthermore, it can be provided as an alternative or in addition to the other embodiments, that the unit is a pressure sensor in one of a vacuum pump to the Austrian Patent Office AT13 518U1 2014-02-15
    Bleeding leading vacuum line is. By saving the at least one pressure sensor, the device according to the invention can be made simpler.
    A similar solution may consist in that the unit is a arranged in a discharge from the outlets discharge line for discharging the coating medium arranged pressure sensor.
    Furthermore, it can be provided that the unit is a control unit for the deaerator.
    In a further, alternative or additional embodiment of the invention can be provided that the unit is a drive device for driving drums of the breather. In this way, a further considerable simplification of the device according to the invention for degassing of the coating medium is achieved.
    In this case, a structurally very simple development consists in that the drive means comprises a belt which connects the drums of the ventilator associated drive shafts together.
    In order to be able to control the flow of the coating medium conducted to the deaerators, a valve can furthermore be arranged in a line leading to the deaerators and / or in a line leading away from the deaerators.
    In claim 10, an apparatus for coating a fibrous web with a device according to the invention for venting the to be applied to the fibrous web coating medium is given.
    Hereinafter, an embodiment of the invention with reference to the drawing is shown in principle.
    The sole FIGURE shows a device according to the invention for venting a coating medium to be applied to a fibrous web.
    A device 1 shown in the figure is used to vent a aufzutragenden on a fiber web, not shown coating medium. In this context, the term " vent " meant the removal of any gases from the coating medium, i. H. the device 1 is capable of removing any gases from the coating medium. The fibrous web to be coated with the coating medium is preferably a paper or board web. The device 1 may be part of a coating device, not shown, with which the fiber web is coated with the coating medium. In this case, the device 1 would preferably be downstream of an application device for applying the coating medium to the fiber web.
    The device 1 has two mutually parallel breather 2 and 3, the structure and operation of which can be known per se and therefore not described in detail below. The breather 2 and 3 are designed for venting the coating medium and can be used on an equal footing. The maximum amount of coating medium to be degassed with a single deaerator 2 or 3 may be, for example, 80 l / min. In order to generate the required inside the breather 2 and 3, a negative pressure generated as a negative pressure pump 4 vacuum generating device is provided, which is arranged in a leading to the vent 2 and 3 vacuum line 5. In order to be able to supply both ventilators 2 and 3, the vacuum line 5 divides into two partial lines 5a and 5b, of which the partial line 5a leads to the ventilator 2 and the partial line 5b to the ventilator 3. The capacity of the vacuum pump 4 should be sufficient to create a sufficient negative pressure in the two vents 2 and 3, since in normal operation, the capacity of the vacuum pump 4 is usually not completely needed.
    The coating medium is conveyed via a feed line 6, in which there is a feed pump 7, to the vents 2 and 3. In the flow direction of the coating medium after the feed pump 7, the supply line 6 divides into two sub-lines 6a and 6b, of which the sub-line 6a leads to the breather 2 and the sub-line 6b to the breather 3. A discharge pump 8 is used to remove the deaerated or degassed coating medium from the vents 2 and 3 and is arranged for this purpose in a discharge line 9, in which in the "; A " Designate flow direction of the coating medium in front of the discharge pump 8 two partial lines 9a and 9b open.
    In the present case, the vacuum pump 4, the feed pump 7 and the discharge 8 units which are in operative connection with the two vents 2 and 3 and which serve to supply both breather 2 and 3 or are arranged.
    For the purposes of the invention, separate sub-pressure pumps 4, 7 and / or feed pumps 8 could be provided for the two breather 2 and 3, as long as at least one with the breather 2 and 3 operatively connected unit to supply both breathers. 2 and 3 is arranged or serves.
    In such an aggregate may also be a pressure sensor 10 which is arranged in the vacuum line 5, which leads from the vacuum pump 4 to the vents 2 and 3 and which serves to measure the pressure prevailing in the vacuum line 5 negative pressure. In the present case, the pressure sensor 10 is located at the point at which the vacuum line 5 divides into the two sub-lines 5a and 5b. Of course, the pressure sensor 10 could also be located at a different position within the portion of the vacuum line 5, which is located between the vacuum pump 4 and the point at which the vacuum line 5 divides into the sub-pipes 5a and 5b.
    Another such unit, which serves to supply both breather 2 and 3, is arranged in the discharge line 9, another pressure sensor 11, which serves to measure the pressure within the discharge line 9. The pressure sensor 11 is arranged at the point where the two partial lines 9a and 9b unite to the discharge line 9. It would also be possible to arrange the pressure sensor 11 in the discharge line 9 at a position closer to the discharge pump 8.
    When the breathers 2 and 3 are at the same height level, d. H. if the bottoms of the breathers 2 and 3 are at the same level, one and the same sensor can be used to measure the level of the coating medium in the breathers 2 and 3.
    Furthermore, in one or more of the sub-lines 6a, 6b, 9a or 9b, a valve 12 may be arranged, with which the flow of the coating medium can be controlled. In the present case, the valve 12 is arranged in all sub-lines 6a, 6b, 9a or 9b, but this is only to be regarded as exemplary. The valve 12 may be adjustable or not adjustable.
    In the embodiment shown in the figure, therefore, the vacuum pump 4, the feed pump 7, the discharge pump 8, the pressure sensor 10 and the pressure sensor 11 are provided for both breathers 2 and 3, which is particularly effective in terms of saving Components and thus to be considered in terms of cost savings. However, it would also be possible to have one or more of these aggregates double, i. H. to be provided separately for each breather 2 and 3. In general, at least one of said units is provided only once and arranged to supply the two breathers 2 and 3. Such an aggregate used jointly for both ventilators 2 and 3 may also be an unillustrated control unit or the like.
    In the illustrated embodiment, two breathers 2 and 3 are provided, but it would also be possible in principle, more than the two breathers 2 and 3 to arrange parallel to each other, in order to increase the capacity for degassing of the coating medium in this way.
    In a manner not shown, a drive device, which drives respective drums of the breather 2 and 3, for both breathers 2 and 3 are used together. For this purpose, for example, a belt may be provided which connects respective drive shafts of the drums with each other. 3.5
