Definitions
- the invention relates to a device for applying small amounts of flowable substances to a sheet-like support, e.g. a sheet-like material web, by means of a magnetically pressed application roller.
- the device generating the magnetic contact pressure and also the application roller are arranged obliquely from the vertical direction and that the application roller is assigned a device for supplying the substance to be applied.
- the device for supplying the substance to be applied is a trough, the trough region which is open for the filling can be freely viewed and is freely accessible. If you give this trough the function of a doctor blade at the same time, there is only an extremely minimal fluid requirement, about 1 liter per meter of length, necessary for the filling of the trough, which is ideal for patterning and small-scale production, and substances which decompose easily and have a short service life can also be used.
- Another advantage of the invention is that the so-called metering roller can be dimensioned larger when two rollers are arranged on the side, since this roller can rest on it, thus relieving the weight.
- an axial drive can be used with which a differential speed can be achieved. This results, in particular, in advance of the applicator roller. With such an advance, there is an additional quantity control, namely an increase in quantity. A reduction in quantity is possible in the event of lag.
- the application and metering rollers are self-cleaning when they advance, since the rollers are slowly wiped off.
- Fig.l shows an embodiment of the invention.
- Fig. 2 shows another embodiment with a special mounting of the metering roller.
- Fig. 3 is an embodiment with a single roller.
- 4 shows an exemplary embodiment of the invention, in which the device generating the magnetic contact force is designed as a magnetic bar.
- Figure 5 is another embodiment.
- FIG. 1 there is a magnet system 2 in a magnetic roller 1, which is offset with respect to the vertical 3.
- An application roller 4 also bears against the magnetic roller 1 with respect to the vertical 3.
- This application roller 4 is assigned a metering roller 5, which dips into the substance 6 to be applied and feeds it to the application roller 4.
- the substance 6 is located in a trough 7, which has a surface 8 directed against the magnetic roller 1, on which the metering roller 5 rests. This makes it possible to increase the diameter of the metering roller, since the magnet system 2 does not have to bear the weight of the application roller 4 and metering roller 5, but the surface 8 relieves the weight.
- FIG. 1 Another embodiment is shown in FIG.
- the axes of the metering roller 5 and the application roller 4 lie in a different plane than the longitudinal axis 9 of the magnet system 2.
- the trough 7 has a recess 10 in which the metering roller 5 is arranged.
- This Ausnelimung 10 has a diameter which is slightly larger than the diameter of the metering roller 5, so that the metering roller 5 floats in the bearing shell formed by the recess 10 and during operation, i.e. when it is twisted through the wall.
- Both the applicator roller 4 and the metering roller 5 have no axle bearings, so they are freely movable, and the three existing rollers, i.e. Magnet roller 1, applicator roller 4 and metering roller 5 support each other.
- the magnet system 2 is arranged approximately 45 ° from the vertical and can be pivotable about the magnet roller axis, as a result of which the oblique forces and also the force distribution on both rollers 4, 5 can be changed.
- the wall of the recess 10 can, under certain circumstances, be grooved and the metering roller 5 can also have a surface structure, to be precise it can be rasterized, edged, axially grooved or rough, but smooth rollers can also be used as the metering roller 5. It is possible to work almost completely air-free. If coating is desired, the metering roller 5 can be smooth, whereas the application roller 4 is structured. After the application, there may still be a smoothing knife.
- the web 11 is also shown, which is first guided over a slide bar 12, which optionally spreads the web 11, and only then passes between the application roller 4 and the magnetic roller 1. It is also possible to provide the applicator roller 4 with a resilient surface, for example made of soft rubber, and both the applicator roller 4 and the metering roller 5 are made of magnetizable material.
- FIG. 3 shows an embodiment in which the metering and application roller are replaced by a single roller 13.
- This roller 13 lies in the recess 10 of the trough 7 and its diameter can be adapted to the respective needs and it can also be provided with any surface.
- the magnet system 2 also serves here, among other things, to press the roller 13 into the coating 10.
- a zone for a lint brush or suction can be provided above the roller 13. It is advantageous if the trough 7 can be moved with respect to the magnetic roller 1 in order to enable automatic adjustment and also to compensate for irregularities in the web 11.
- An additional drive can be present both in the embodiment of the invention with metering and application roller and in the embodiment with only one roller, so that the roller serving as application roller advances.
- the peripheral speed can be regulated very precisely and the amount of substance applied can also be controlled in this way.
- Voroiling means increasing the amount of substance and lagging
- Reduction in the amount of substance is also important is self-cleaning when leading, especially when applied to carriers that show abrasion, e.g. Fiberglass.
- the advance can be selected precisely by selecting the speeds. In this case, the
- Application rollers should be as smooth as possible.
- the device generating the magnetic contact pressure does not have to be designed as a magnetic roller, but it is also possible to provide a magnetic bar. This is shown in Fig.4.
- a magnetic bar instead of the magnetic roller 1.
- Such magnetic bars 14 are known per se. They generally have a table surface 15 over which the web 11 is guided. In the table surface 15 or in its immediate vicinity, the magnet system 2 inserted in the magnetic bar 14 ends, generally an electromagnet, which has a magnet coil and an iron core.
- the axis 16 of the magnet system is arranged at an angle to the vertical 3.
- the application roller 4 In the area of the table surface 15, the application roller 4 is pressed against the web 11 and the substance 6 to be applied is fed to it via the metering roller 5.
- This substance to be applied is in turn located in a trough which has a surface 8 directed towards the table surface 15. It is possible to design the magnetic bar 14 to be displaceable in order to be able to change the relative position to the trough and thus to the application roller 4, or to arrange the magnetic bar 14 so as to be pivotable, likewise in order to enable a change in position relative to the application roller 4.
- a trough 7 with the flowable substance 6 to be applied to a web 11 is provided.
- the metering and application roller is again formed by a single roller 13, with an additional friction drive for the roller possibly being provided.
- the roller can either be mounted by means of the stub axle 21 or it can rest on the base 19 which carries the ribs 20 so that dosing can also take place on this base.
- In the trough 7 there is also a strip of material 17 which projects beyond the upper edge of the trough and carries a roller 18.
- the web 11 slides over this roller 18 and above the roller 18 an additional storage space is defined which is defined by the roller 13 and the web 11 and is filled in a defined manner.
- the web 11 in turn rests on a counter surface to the roller 13.
- the counter surface can be given by a Magnetwal ze 1 with a magnet system 2 or by a magnetic bar.
- the axis of the magnet system 2 in turn encloses an angle with the vertical and is also offset in relation to the axis of rotation of the roller 13 in the illustration in FIG.
- the material strip 17 and / or the body carrying the sliding surface 18 for the web 11 can optionally also consist of a magnetizable material and be attracted to the magnet system 2.
- the material strip 17 can have a pretension which then acts as a counterforce to the applied magnetic force. In this way, the storage space can be precisely defined within given limits.
