    description
    DEVICE FOR CLEANING AND / OR CONDITIONING A TENSION
    The invention relates to a device for cleaning and / or conditioning a machine clothing, such as a felt covering in a machine for producing a fibrous web, with at least one traversing sensor device, with the data regarding the properties of the machine clothing can be determined, and a cleaning nozzle, for cleaning and conditioning the clothing.
    In a machine for producing a fibrous web, it is necessary to clean the clothing continuously and / or to condition. Especially with the felt covers in the machine, it is necessary to keep the conditions of the felt constant.
    Thus, for example, in a paper machine, a plurality of fabrics used for transport and dewatering of a fibrous web to be produced. The fabrics here are, for example, in the form of forming fabrics in the forming section, in the form of press felts in the press section and in the form of dryer fabrics in the dryer section or as transfer belts. Often the screens and felts are at least partially designed as fabric tapes with open pore structure.
    Several devices for cleaning a fabric of a web-processing machine are known from the prior art.
    For continuous online measurement of felt moisture, permeability and temperature, at least one traversing sensor device is known from the prior art, by means of which one-sided position-accurate measurements can be carried out.
    A felt or sieve removable.
    Felt or screen properties are determined and stored in a database. With an evaluation and / or control unit appropriate countermeasures are then triggered, which may for example consist in the change of spray tube pressures or Rohrsaugervakua.
    The monitoring can be done permanently or in cyclic intervals.
    From EP 1 707 670 a method and a device is known for improving the conditioning, which takes into account the specific structure of the fabric to improve the cleaning and conditioning.
    The cleaning result achieved with these cleaning devices and the specified measures is, with the increased quality requirements for a uniform conditioning of the fabric, not always sufficient.
    It is the object of the present invention to provide a device and a method for targeted cleaning and / or conditioning of a fabric, with the / an improved and more uniform conditioning of the fabric is made possible.
    The object is achieved by means of a device having the features of claim 1 and the method according to claim 9.
    According to the invention, a device of the type mentioned is proposed in which the cleaning nozzle is arranged together with the sensor device on a holding device and is movable transversely to the direction of the clothing and can be controlled or regulated by means of the measured data from the sensor device.
    The requirements for a more uniform cleaning and / or conditioning of the covering is now possible because the cleaning device promptly after the measurement of a defective area, this can clean. Especially in the edge areas of the covering or if it is due to contamination to streaking in the 1/6 Austrian Patent Office AT13 659U1 2014-05-15
    Fibrous web is coming this is an advantage.
    To further improve the cleaning and / or conditioning of the cleaning nozzle is associated with a suction device, which is arranged on the opposite side of the fabric, on a guide device, and on this transverse to the transport direction of the machine clothing, parallel to the cleaning nozzle, moves can.
    But the cleaning nozzle can also be assigned a bespannungsbreite suction. In order to reduce the Saugluft- or vacuum demand, the suction device may have a plurality of suction zones over the web width and / or in the machine longitudinal direction, which are individually supplied with suction air.
    The sensor device may comprise a permeability sensor and / or a water weight sensor and / or a temperature sensor.
    Furthermore, the cleaning nozzle consist of several individual nozzles, which can be controlled individually and / or jointly, so that the individual nozzles different cleaning or conditioning tasks can be assigned. The individual nozzles can be designed in such a way that a fluid with different angles can be directed onto the clothing.
    In addition, it is useful in the use of individual nozzles to associate the individual nozzles with a suction device.
    Furthermore, a method for cleaning and / or conditioning a machine clothing with at least one traversing sensor device, are determined with the data in terms of the properties of the machine clothing, and a cleaning nozzle, for cleaning and conditioning of the fabric proposed, the cleaning nozzle together with the sensor device is arranged on a holding device and is moved transversely to the running direction of the clothing and is controlled or regulated by means of the data measured by the sensor device.
    To further improve the cleaning effect, the cleaning nozzle may consist of several individual nozzles, which are controlled individually and / or jointly.
    Furthermore, to reduce the cleaning effort, the cleaning device can be controlled so that only the areas of the fabric are cleaned and / or conditioned, through which a deterioration of the fibrous web quality occurs.
    In particular, the edge regions of the fabric can be cleaned and / or conditioned, if this occurs a deterioration of the fibrous web quality.
    Furthermore, an independently traversing cleaning device may be provided, with which the fabric is cleaned continuously, so the cleaning can be divided into a continuous main cleaning and a partial intensive cleaning.
    The invention will be explained in more detail with reference to drawings.
    2 shows a view of the cleaning and / or conditioning device in the machine running direction. [0029] FIG. 3 shows two exemplary cleaning nozzles with associated suction devices. [0029] FIG Figure 1 shows a plan view of the cleaning and / or conditioning and Figure 2 is a view in the machine direction. In the chosen embodiment, the covering, e.g. a forming fabric or a felt covering, guided by a frame construction, guide device 9. This has a traversing device with a holding device 4, to which a cleaning and / or conditioning device or cleaning nozzle 5 and a sensor are attached. Between the cleaning nozzle 5 and the sensor, the control and control unit is arranged, with which the cleaning nozzle 5 is controlled or regulated.
    Opposite the cleaning nozzle 5, the suction device 6 is arranged, which is also attached to a traverse device. The suction device 6 is subjected to vacuum. The vacuum supports the cleaning action of the cleaning nozzle to maximize flow through the felt for maximum cleaning efficiency. Through the cleaning nozzle, a cleaning medium, water, water / air mixture or suitable chemicals, passed. The cleaning nozzle and the suction device are moved in parallel or synchronously.
    The cleaning and / or conditioning of the fabric can be done either from the clothing top or underside of the clothing.
    Furthermore, in each case a cleaning nozzle 5 can be positioned on both sides of the sensor 7 or in the web running direction before and / or behind the sensor 7.
    In Figure 3, two exemplary cleaning nozzles are shown with associated suction devices. Once a single nozzle with a suction device arranged underneath. The suction device may alternatively be run web width and be divided into several suction zones, which are individually supplied with vacuum.
    The second nozzle 5 shown below consists of a plurality of individual nozzles 5a-d, which direct the cleaning medium with different angles on the fabric 1. One of the cleaning nozzles 5a is optimized in such a way that the surface is freed of dirt, a further cleaning nozzle 5b is optimized together with the associated suction device 6b for deep cleaning, furthermore a conditioning nozzle 5c with associated suction device 6c is provided, which treats the clothing with a cleaning chemical and then again followed by a cleaning nozzle 5d with associated suction device for post-cleaning 6d.
