Definitions

  • the invention relates to a device for applying at least one liquid medium to a running material web, in particular made of paper or cardboard, according to the preamble of patent claim 1.
  • a liquid medium such as paint, impregnating liquid, starch or the like, is applied to the material web.
  • the liquid medium can have a different consistency, ie, for example, it can be thick or thin.
  • the material web can be made of paper or cardboard, but it can also consist of a textile material, for example.
  • the liquid medium is applied to the running material web either directly or indirectly. In the case of direct application, the material web is guided past the application unit on the outer surface of a roller, and the liquid medium is applied directly to the material unit as it passes through the application unit.
  • the roller serves as a counter roller to the applicator.
  • the roller acts as an application roller, ie the liquid medium is first applied to the application roller and then by the roller touching it removed material web removed, preferably in a two-roll nip.
  • the drying devices for the web of material treated with the liquid medium are arranged with respect to the horizontal plane in an area above the roller, which considerably facilitates the heat dissipation for the drying devices, since then the heat dissipation upwards is not impeded by the application devices.
  • the dirty cleaning waste water can drip onto the drying devices when cleaning the application device.
  • German utility model DE-GM 84 14 904.3 an application is described which, viewed in section, is arranged in the six o'clock position of the counter roller.
  • a disadvantage of the described work is that the work can only be arranged in a small area around the position described, since the excess medium can no longer be guaranteed in the event of major deviations.
  • the material web can only be viewed with difficulty by the operating personnel, which makes visual inspection of the line quality virtually impossible.
  • an applicator unit which has a metering knife and a baffle bar arranged at a distance from the metering knife counter to the direction of rotation of the roller and which limits an application chamber with the metering knife.
  • the application unit is arranged according to the invention in a downward-running sector of the lateral surface of the roller.
  • the applicator is arranged with respect to a vertical plane running through the roll axis on that half of the roll lateral surface in which a point on the lateral surface of the roll moves from top to bottom with respect to a horizontal plane due to the roll rotation.
  • the baffle bar is arranged at a distance from the metering doctor against the direction of rotation of the roller, it is thus spatially higher than the metering doctor with respect to a horizontal plane.
  • a drainage surface is provided according to the invention which includes an acute angle with a horizontal plane.
  • the baffle bar is arranged spatially higher than the metering doctor and thus excess medium must first emerge from the application chamber against the direction of action of gravity, ie must flow out upwards, problem-free outflow of excess liquid medium is achieved according to the invention.
  • the excess liquid medium flows between the roller and the baffle bar the direction of rotation of the roller and thereby ensures an effective detachment of the air boundary layer from the surface of the roller.
  • the air boundary layer could otherwise reach the metering knife through the application chamber and lead to a faulty line due to the formation of air bubbles.
  • the device according to the invention can also be used advantageously for direct application of a liquid medium to a material web which is guided around a counter roller. Analogous to the arrangement described above, in the case of indirect application after direct application, the operator can visually check the applied line on the material web from below. Furthermore, in the device according to the invention, a coating unit according to the invention can be arranged on the lower half of the roller shell with respect to a horizontal plane running through the roller axis, and an additional coating unit in the second quarter circle sector in which the peripheral surface runs upwards be provided in a conventional manner. For example, two different lines can appear one after the other in the case of direct application the material web are applied. Of course, the application unit arranged according to the invention can also be arranged in the downward half of the roll surface area above the horizontal plane running through the roll axis.
  • the downward-running sector of the roll surface, in which the application unit is arranged extends preferably with respect to a horizontal plane running through the roll axis by an arc angle range of 30 ° upwards and an arc angle range of 90 ° downwards.
  • the application unit can be arranged in a downward-running sector of the roll surface, which extends downward from a horizontal plane running through the roll axis in an arc angle range of 90 °. This corresponds to a range from approximately the three o'clock position to approximately the six o'clock position of the roll circumferential surface when the roller rotates clockwise and an area from the nine o'clock position to the six o'clock position when the roller rotates counterclockwise -Position.
  • a preferred position for the arrangement of the application unit for a roller rotation in the clockwise direction is the four o'clock position, i.e. the position at an arc angle of approx.
  • the application unit with a pressing device for the metering doctor, the pressing force of which can be variably adjusted over the roller width.
  • the cross profile of a line applied to a material web that is to say the line profile in the direction transverse to the direction of travel of the material web, can thus be set precisely.
  • the pressure force is set either manually or by means of a motor by means of adjusting elements. These adjusting elements, such as adjusting spindles, then, distributed over the width of the roller, press on a pressing element, such as a pressure hose filled with compressed air.
  • a preferred embodiment of the invention is to design the adjusting elements as flexible spindle shafts, so that the spatial course of these can be adapted well to the structural conditions of the application work and, for example, can be led outside around the application work to the pressure element.
  • the local contact pressure of the adjusting spindles on the pressure element and thus the local contact pressure of the doctor element against the roller can be regulated by appropriate adjustment of the various adjusting spindles, either by hand with adjusting handwheels or automatically by means of servomotors.
  • Another feature of the invention is that the force that holds the squeegee holder in the applicator is almost perpendicular or at an angle greater than 90 ° to the force that presses the squeegee element against the roller.
  • the squeegee holder is easily detachable in this way.
  • two embodiments are preferred for the relative arrangement of the drainage surface and a feed channel for the liquid medium to one another.
  • the feed channel and the discharge surface in such a way that they each extend on different sides of the baffle bar with respect to a roller circumferential direction.
  • the feed paths for the liquid medium to the application chamber can then be arranged spatially separate from the discharge paths for excess liquid medium. This leads to a relatively uncomplicated design of the feed and discharge paths.
  • Adjusting elements for regulating the pressure force of the metering doctor can then be guided around the application unit, for example in the form of flexible spindle shafts, if otherwise a radial course of the spindle shafts would have to lead to the metering doctor through the feed paths for the liquid medium.
  • a second inexpensive variant consists in arranging the drainage surface and a feed channel for the liquid medium on the same side of the storage rail. The discharge paths for the excess liquid medium, for example from the drainage surface into a gutter, and the paths from the feed channel to the application chamber can then be designed so that they cross each other.
  • This variant allows the actuating elements, for example the adjusting spindles, to be fed approximately radially with respect to the roller axis to the metering doctor, without crossing the feed paths of the liquid medium.
  • This type is particularly suitable for an arrangement in the three o'clock position.
  • a feed nip for feeding the liquid medium into the application chamber in such a way that it opens approximately radially into the application chamber with respect to the roller axis.
  • Fig. 1 shows a machine for applying a liquid medium, e.g. Starch or a liquid with color pigments, on a material web 1, which e.g. consists of paper or cardboard.

  • Two rolls 2 form a roll nip between them and each rotate in the direction of rotation indicated by an arrow, so that the material web 1 is conveyed through the roll nip from bottom to top with respect to a horizontal plane.
  • mirror-symmetrical applicator units 3 are arranged, with which the liquid medium is applied to the lateral surfaces of the rollers 2, in order then to be transferred from the rollers in the nip to the material web 1, as a result of which the liquid medium is applied to the material web on both sides he follows.
  • the two applicator units 3 are each arranged at a position on the rollers 2 at which a point on the surface of the roller surface moves downward with respect to a horizontal plane.
  • the right application unit 3 is arranged with respect to the associated roller 2, which rotates clockwise, at a position which would correspond to the four o'clock position on a clock face projected onto the roller cross section.
  • the left applicator unit 3 is arranged on the left, counterclockwise rotating roller 2 at a position which would correspond to the eight o'clock position on a clock face.
  • the structural details of the mounting of the applicator units 3 on the machine arrangement are not discussed in detail here, since this corresponds to a conventional design.
  • the operating personnel in the configuration shown can be seen from below on each roller 2 in the area between the application unit 3 and the material web 1 check the quality of the liquid film applied to the rollers. In this way, possible errors in the film can be easily recognized on the rollers and clearly assigned to the respective application. On the other hand, this assignment is no longer possible with certainty after the liquid medium has been applied to the material web on both sides in transmitted light.
