Definitions

  • the invention relates to an applicator for applying a liquid or pasty medium to a running web of material, in particular made of paper or cardboard, according to the preamble of claim 1.
  • Such a applicator for applying a liquid or pasty medium to a running material web is known from the utility model G 94 17 321.4 of the applicant, the zone of applying the application medium to the material web running on a roller from an application chamber connected to a central distribution tube or a starts as a free jet nozzle between a metering gap designed on the inlet side and a lip on the outlet side. If the metering gap designed as a free jet nozzle is used, a concave curved guide surface, which adjoins the metering gap, is provided for the liquid or pasty medium at the free end of the lip on the inlet side.
  • the entire applicator unit can be pivoted to adjust the angular position of the application chamber or the free jet nozzle with respect to the tangent to the running material web about an axis parallel to the central axis of the roller, the axis being at least approximately on the extension of a straight line starting from the central axis of the roller passes through a point close to the application zone. In this way it is possible to swivel the entire applicator into a service position for maintenance or cleaning purposes, for example. Due to the pivotability of this application mechanism, a certain variation of the jet impact angle of the liquid or pasty medium emerging from the free jet nozzle is also possible.
  • the invention is therefore based on the object of providing a coating unit with which the angle of incidence of the liquid or pasty medium on the application roller or the running material web is made possible in a simple and effective manner within a wide angular range.
  • the guide surface above the outlet of the metering gap is designed to be pivotable about an axis running essentially parallel to the longitudinal extent of the application unit.
  • the application unit according to the invention allows the angle of incidence of the liquid or pasty medium to be set on the application roller or the running material web in a large angular range in an advantageous, simple and effective manner. All that is required for this is the adjustment, that is to say pivoting, of a very small component of the application unit, namely the guide surface, as a result of which the production outlay and the production costs are considerably reduced.
  • the forces acting on the structural components of the applicator structure by adjusting or adjusting the guide surface can be kept small and a light and inexpensive construction can thus be achieved. This is also desirable from a technical and economic point of view.
  • the entire nozzle chamber can also be used in the application unit according to the invention with its special impact angle setting including the commonly used support beam remain in a normal, fixed working position, which eliminates the need for complex and expensive adjustment mechanisms. There are also no bearing play of such adjustment mechanisms and consequently have no influence on the angle of incidence, which enables a very precise adjustment of the angle of incidence. Since the pivot axis of the guide surface is in the immediate vicinity of the material web, the displacement of the "impact line" of the liquid or pasty medium onto the running material web is negligibly small when the angle of incidence is adjusted. Finally, the application mechanism according to the invention can be cleaned more easily and with less effort due to its simple impact angle setting device. For this purpose, for example, a front flap or the like comprising the lip on the outlet side can be provided, which is structurally particularly simple to implement in comparison with conventional applicators.
  • An advantageous design feature of the invention provides that the guide surface above the outlet of the metering gap is designed to be pivotable in zones about an axis running essentially parallel to the longitudinal extent of the application unit.
  • the guide surface is expediently divided into zones.
  • the angle of incidence of the liquid or pasty medium on the running web of material can be changed locally and thus the application to the application roller or the web of material can be influenced accordingly.
  • This can be useful, for example, to compensate for local manufacturing inaccuracies or to create a specific cross section on the material web.
  • a joint or hinge device is provided in the inlet-side and / or outlet-side lip and / or in a component of the applicator device assigned to the guide surface, the joint or hinge device ensuring that the guide surface can be pivoted.
  • a component assigned to the guide surface is understood to mean, for example, a special holder or the like for the guide surface, this holder being able to be arranged on the inlet-side or outlet-side lip or another suitable component of the application unit, as required.
  • any device suitable for the intended purpose can be considered as a joint or hinge device, but care must be taken to ensure that the transition between the outlet of the metering gap and the guide surface is as streamlined as possible. In this way, an angle of incidence can in turn be implemented particularly easily.
  • a local thin point is provided in the area of the outlet of the metering gap in the inlet and / or outlet lip and / or in a component of the applicator assigned to the guide surface, the local thin point ensuring the pivotability of the guide surface by flexible deformation, can be very simple and effective desired setting or adjustment of the guide surface can be realized.
  • the local thin point thus acts as a hinge and also enables a transition that is very streamlined for the liquid or pasty medium at the point of adjustment.
  • the joint or hinge device or the local thin point lies in a range of approximately 0 mm to 20 mm above the outlet of the metering gap, that is to say above the greatest extent of the lip on the inlet and / or outlet side.
  • an impact angle setting can be carried out independently of a metering gap adjustment.
  • the invention is not restricted to the aforementioned special area. Rather, the position of the articulated or hinge device or the local thin point can vary considerably from the values mentioned, depending on the application and the respective requirements.
  • At least one adjusting device is advantageously provided for pivoting the guide surface.
  • these can also be arranged distributed over the length of the application unit.
  • This embodiment is particularly suitable for a zoned guiding surface. It is of course expedient to assign a separate adjusting device to each zone of the guide surface.
  • a mechanical adjustment mechanism can include, for example, levers, eccentrics, set screws and the like.
  • the mechanical adjustment mechanism has at least one lever arm arrangement which directly or indirectly introduces bending forces into the guide surface via at least one actuator, in order to achieve a pivoting of the guide surface by means of the resulting bending deformation of the guide surface.
  • This embodiment is particularly suitable in connection with the Above mentioned, provided in the area of the exit of the metering gap local thin point, which ensures the pivotability of the guide surface; the local thin point is deformed flexibly, while the geometry of the guide surface itself remains essentially unchanged.
  • the lever arm arrangement it is also possible to easily adjust the guide surface over the entire length of the application work or in zones. Indirect introduction of bending forces into the guide surface can take place, for example, via intermediate power transmission elements or the like.
  • the mechanical adjustment mechanism preferably has at least one adjustment device, which is supported directly or indirectly on the inlet-side and / or outlet-side lip and / or on a bar of the application unit.
  • the adjustment device itself can of course also serve as the adjustment device, or vice versa.
  • the adjusting device for example an adjusting screw pretensioned by spring elements, a servomotor for fine adjustment or the like, the guide surface can be pivoted in a desired manner and the angle of incidence of the liquid or pasty medium can be set very finely.
  • the adjusting device for example an adjusting screw pretensioned by spring elements, a servomotor for fine adjustment or the like
  • the guide surface can be pivoted in a desired manner and the angle of incidence of the liquid or pasty medium can be set very finely.
  • the adjustment device has a thermal, hydraulic, pneumatic, electrical, electromagnetic, magnetic, magnetostrictive or piezoelectric adjustment mechanism.
  • This In principle, adjustment mechanisms can be combined both with one another and with the mechanical adjustment mechanism mentioned above, and their constructive design can be implemented in a variety of ways and adapted to the intended purpose. They are also particularly suitable in connection with automatic control or regulation devices.
  • a further advantageous embodiment of the invention consists in the fact that the adjusting device can be operated automatically and / or remotely and / or is integrated in a control loop. This is particularly useful with regard to an angle of incidence setting during the ongoing operation of the application unit.
  • the adjustment device can then be controlled centrally, on the one hand, and on the other hand, a control-related linkage of the adjustment device with other components of the application mechanism is made possible.
  • the automatic and / or remote-controlled actuation of the adjustment device is integrated in an automatic control circuit which adjusts the adjustment device for the angle of incidence based on measured values of the cross profile or other properties of the applied liquid or pasty medium. This allows the application to be adapted as quickly as possible to changing conditions and also avoids longer downtimes.
  • the inlet side lip can be adjusted continuously and / or zone-wise over the machine width of the application unit with the adjustment device.
  • the lip on the inlet side can be adjusted manually and / or automatically during or outside the ongoing operation of the application unit.
  • a particular advantage also arises from the fact that the setting of the lip on the inlet side and thus also the metering gap setting are independent of the impact angle setting realized with the aid of the guide surface can be carried out, and vice versa.
  • the setting of the lip on the inlet side and the angle of incidence can accordingly be coordinated with one another depending on the type of liquid or pasty medium used and depending on other influencing factors in order to achieve a high-quality application. This in turn allows the application to be optimally adapted to changing conditions, particularly during operation, and helps to avoid longer, costly downtimes.
