Definitions
- the invention relates to a device for suctioning an air boundary layer from a running material web deflected by a roller and a device for coating a running material web with such a suction device.
- curtain coaters are known for coating running material webs such as paper or cardboard webs, plastic or metal foils, in which the coating material (adhesive dispersions, pigment coating color, etc.) is applied to the material web from a slot nozzle in a free-falling curtain.
- the coating material adheresive dispersions, pigment coating color, etc.
- the curtain falling out of the slot nozzle is placed on the web in a stable manner, without fluctuations and without air pockets.
- the air boundary layer adhering to the web causes problems, in particular at high web speeds of more than 400 m / min.
- the air boundary layer adhering to the web triggers irregular fluctuations in the curtain and leads to air pockets that lead to unevenness in the coating thickness.
- a curtain coater for the production of photographic materials is known from EP 0489978-A1, in which a shield-shaped element (“air shieid”), which serves to remove the air boundary layer, is arranged in front of the slot nozzle.
- the element is in the region of a deflection roller arranged for the web and extends in a curved arc over a certain angular range of the deflection roller.
- the element is designed in such a way that zones are determined in the inlet area and in the outlet area in which the air resistance is greater than in a zone between the two areas. In the zone There is a chamber between the areas with greater air resistance, which is connected to a suction pump to reduce the pressure. is.
- the distance between the sealing elements on the inlet and outlet sides and the deflection roller is between 0.5 mm and 2 mm.
- the distance between the outlet-side end of the shield-shaped element and the curtain is between 5 mm and 30 mm.
- the invention has for its object to provide a device which makes it possible to reduce the air boundary layer of a wide (3 m and more) web at high web speeds (1000 m / min and more) so that a curtain coater arranged downstream apply the coating material evenly.
- the suction box which extends across the axial length of the deflecting roller, is open towards the deflecting roller and connected to a suction fan.
- the suction box On each end face of the deflection roller, the suction box contains an end-face seal, which extends parallel to the outside and parallel to it at a short distance from it,
- the outlet-side seal forms an outlet gap with the web, the height and length of which, measured in the web running direction, is essentially constant over the entire width of the suction box, the length being more than 10 mm, preferably more than 30 mm, in particular 50 mm-70 mm, is and the gap height is selected depending on the web speed so that the value of the product web speed (in m / min) x gap height (in mm) is less than 1500.
- air shieid is used, but a suction box to suck off the air boundary layer. It has been shown that the design of the outlet-side seal is of crucial importance for the suction effect.
- Figure 1 shows the side view of a curtain coater, in which the slot nozzle is arranged so that the curtain falls along the apex line of a deflection roller supporting the web on the web.
- Figure 2 shows an enlarged view of the device for suction of the air boundary layer.
- FIG. 3 shows a curtain coater in which the curtain made of coating material falls onto the web behind the deflecting roller.
- Figure 4 shows the suction device of the curtain coater according to Figure 3 in an enlarged view.
- the coating device shown in the figures is used to apply a dispersion pressure sensitive adhesive (for example an acrylate) in aqueous solution to a siliconized paper web 1. Because of its advantageous properties, the dispersion pressure sensitive adhesive (for example an acrylate) in aqueous solution to a siliconized paper web 1. Because of its advantageous properties, the dispersion pressure sensitive adhesive (for example an acrylate) in aqueous solution to a siliconized paper web 1. Because of its advantageous properties, the
- Device also for applying other dispersions on paper, plastic films or use thin tapes or to coat paper or cardboard webs with coating color.
- the coating device contains a slot nozzle 2, which is suspended above the run of the web 1 in a frame.
- the slot nozzle 2 is on a feed for
- Coating material connected and has on its underside a slot-shaped opening from which the coating material emerges and forms a free-falling curtain 3, which falls on the web surface.
- the width of the slot nozzle 2 is greater than the width of the web 1 to be coated.
- the web 1 is deflected by a deflecting roller 4, the axial length of which extends over the entire working width of the coating device, i.e. the maximum width of a web 1 to be coated extends.
- edge channels 5 are arranged below the slot nozzle, which limit the curtain 3 to the desired coating width.
- the edge channels are each attached to the frame of the nozzle 2, so that they are moved when the nozzle 2 is moved in or against the web running direction.
- the coating material separated at the curtain edges is collected in the edge channels 5 and discharged into a collecting trough 6 against the direction of web travel.
- the drip pan 6 is arranged directly in front of the deflection roller 4.
- the slot nozzle 2 is moved with the elements attached to it in the area above the sump 6. A stable curtain 3 is first created there, which falls into the collecting trough 6. The slot nozzle 2 is then moved into its working position above the deflecting roller 4 (FIG. 1) or just behind it (FIG. 3).
- the embodiment according to FIG. 1 serves to apply a coating with a width less than the web width. In this way, coating-free edges remain on the coated web 1.
- the web 1 is coated over its entire width.
- the curtain 3 is wider than the web 1.
- the slot nozzle 2 is in its working position at a distance behind the
- the apex line of the deflecting roller 4 so that a trough 7 can be arranged below the curtain 3, from which the coating material falling to the side next to the web edges is collected.
- the web 1 is guided horizontally in the area below the slot nozzle 2 and then deflected downwards by a second deflecting roller 8.
- a suction device To suction the air boundary layer from the web 1 and the edges of the deflection roller 4 is at a short distance in the direction of web travel arranged a suction device, which is shown enlarged in Figures 2 and 4.
- a suction box 8 is arranged, which is open towards the deflection roller 4 - that is, towards the web 1 - and is connected to a suction blower via at least one suction line 9 opening into the rear wall.
- the suction box 8 extends in width over the entire axial length of the deflection roller 4.
- On its inlet side it has an inlet seal 10 and on its outlet side an outlet seal 11, each of which extends over the axial length of the deflection roller 4 and with the web 1 form a gap 12, 13.
- At least the end of the inlet seal 10 and the beginning of the outlet seal 11 are located in the deflection area of the web 1 on the deflecting roller 4.
- the suction box 8 On each end face of the deflecting roller 4, the suction box 8 contains an end-face seal 14, which is parallel outside at a short distance from the end face this extends.
- the sealing elements 14 extend with a width of at least 10 mm, preferably more than 15 mm, measured radially to the deflecting roller 4, into the end region of the deflecting roller 4.
- the outlet seal 11 is arranged and designed such that an outlet gap 13 forms with the web 1, the height and length measured in the web running direction over the entire width of the suction box 8, that is over the entire axial length of the deflection roller 4, is substantially constant.
- the length of the outlet gap 13 is more than 10 mm, preferably more than 30 mm, in particular 50 mm - 70 mm.
- the height of the outlet gap 13 is selected depending on the web speed so that the value of the product web speed (in m / min) x gap height (in mm) is less than 1500. At a web speed of 1000 m / min, the gap height is therefore less than 1.5 mm.
- the distance measured over the circumference of the roller between the end of the inlet seal 10 and the beginning of the outlet seal 11 is more than 10 mm, preferably 50 mm - 500 mm. In this area, the air boundary layer is sucked off from the web 1 by the negative pressure in the suction box 8. It has been shown that the suction is improved if the inlet seal 10 and the outlet seal 11 are designed such that they each have a sharp edge at their inlet and outlet ends. At least the outlet seal 11 is therefore at its inlet and designed with a sharp edge at its outlet end, preferably the inlet seal 10 also has a correspondingly sharp edge at least at its outlet end.
- the wall 15 is preferably formed by a perforated plate which separates the rear region of the suction chamber 8 with the suction line 9 from the front region, which is open towards the web 1.
- the wall 15 additionally stabilizes the structure of the suction box 8.
- a corona charging electrode 16 is arranged in the suction box 8 and is connected to a high-voltage source.
- a corona charging electrode and its use for detaching a gaseous laminar boundary layer is described in detail in EP 0837824-B1.
- the deflecting roller 4, which is made of a conductive material, for example of metal, and is grounded acts as a counter electrode on the other side of the web.
- the charging electrode 8 extends over the width of the suction box 8 and has a series of parallel tips 17 which are directed towards the web 1. The applied high voltage causes 16 or electrons or positrons to emerge from the tips 17 of the charging electrode, which are in the air boundary layer
- the tips 17 extend as close as possible to the web 1, the distance from the web 1 being 0.1, 10 mm, preferably 1 mm, 5 mm. The distance across the web 1 between two tips 17 is approximately 5 mm.
- the suction box 8 is arranged so that the distance from the end of the outlet seal 11 to the curtain 3 emerging from the slot nozzle 2 is 10 mm - 200 mm, preferably 20 mm - 70 mm. At this distance it is ensured, on the one hand, that no new disturbing air boundary layer builds up on the path of the web to the curtain 3, on the other hand, disturbances of the curtain 3 by suction of air into the outlet gap 13 are avoided.
- the suction box 8 used there and shown in FIG. 4 is of elongated design at its end.
- the end of the suction box 8 with the outlet seal 11 extends over the apex line of the deflection roller 4.
- the upper limit of the suction box 8 is designed so that it protrudes only slightly above the circumference of the deflection roller 4. This makes it possible to arrange the edge channels 5 above the suction box 8 immediately above the web run in such a way that they run downwards slightly towards the web running direction, so that the coating material collected runs off into the tub 6.
- the suction box 8 is preferably mounted so that it can be pivoted away from the deflecting roller 4 so that a new web 1 can be introduced into the coating device.
- its front which is open towards lane 1, is accessible for maintenance work.
