Definitions

the invention relates to a coating device with an application unit for applying a liquid layer to a band-shaped carrier material which is guided over an application roller.
the bearing of the application roller receives special attention since a well executed bearing ensures high running accuracy in the axial and radial direction.
the running accuracy is defined as a deviation from the ideal axis of rotation, the deviation as a sum error from all interacting components on the application roller occurs.
Rolling bearings with particularly high accuracy cannot be less than a deviation of 3 ⁇ m from the ideal axis of rotation. This minimal theoretical radial runout of such roller bearings is increased by further individual errors in the application roller.
the application roller rotates the errors on the left side of the application roller can lead to a reduction in the distance between the application roller and the coating device, while at the same time the distance between the application roller and the coating device increases on the right side.
the device described in DE-A-33 09 343 for applying at least one casting layer to a moving, web-shaped base has a rotating application roller that guides the base.
a caster is located near the application roller, separated only by a gap.
the casting gap can be changed by adjusting the caster with a radial component.
the caster can also be adjusted in any other direction to take into account the numerous factors that need to be taken into account in operation, such as the material properties of the Emulsion and pouring solutions, the layer thickness on the band-shaped carrier material, the range of the casting speed and the like.
no precautions have been taken to take account of unevenness in the layer thickness due to the radial stroke of the application roller and in the play of the bearing of the caster.
European patent specification EP-B - 0 168 986 describes a sliding film coating with negative pressure when the coating solution is applied tangentially.
the sliding film flows down a vertical wall and passes through a gap onto the strip to be coated.
the tape is deflected by a roller so that the coating film lies tangentially on the tape.
the coating device is mounted so as to be rotatably adjustable about the axis of the coating roller, and the angle of the slideway is adjusted within a range from 20 ° to 120 ° to the horizontal.
the housing of the coating device is supported on each side by arms which can be rotated about the axis of the coating roller.
the support arms enable the coating device to be arranged in any position along the circumference of the coating roller. In this known coating device, too, no precautions are taken to compensate for concentricity or bearing errors which impair the constancy of the layer thickness on the carrier material to be coated.
the object of the invention is to errors in the storage of the application roller of a coating device, such as e.g. rolling bearing errors, by eccentricities of the inner rings, dimensional and dimensional errors of the individual rolling elements as well as bearing play, temperature fluctuations and changes in tensile force of the band-shaped carrier material to be coated and the resulting layer thickness fluctuations of the liquid layer applied to the carrier material.
a coating device such as e.g. rolling bearing errors, by eccentricities of the inner rings, dimensional and dimensional errors of the individual rolling elements as well as bearing play, temperature fluctuations and changes in tensile force of the band-shaped carrier material to be coated and the resulting layer thickness fluctuations of the liquid layer applied to the carrier material.
This object is achieved in such a way that a skid is attached near the two end faces of the coating device, which lies under pressure on the application roller.
the two runners are pivoted on the housing of the coating device via pivot pins.
Each of the two skids is equipped with a sliding surface as a skid.
each runner is equipped as a runner runner with two rolls and the rolls rest on the lateral surface of the application roller.
the runners expediently rest on the lateral surface of the application roller or on the edges of the band-shaped carrier material.
prestressed compression springs which bear with their ends against the rear of the coating device and a counter bearing, exert the compressive force on the coating device in order to press its runners against the application roller or the edges of the carrier material guided over the application roller.
pneumatic elements can also exert pressure forces on the back of the coating device and press their runners against the application roller or the edges of the carrier material guided over the application roller.
the pneumatic elements are expediently low-friction bellows cylinders.
the coating device can be adjusted along easily movable, ball or roller bearing guides. Furthermore, the coating device is rotatably connected to the two guides via a bearing on the two outer sides.
the advantage of the invention is that a parallel and dimensionally accurate distance between the coating device for the application of a liquid layer on a moving belt of carrier material and the application roller over which the carrier material band is guided is ensured.
the runners maintain a constant gap between the coating device and the application roller, since all bearing errors and also uneven thicknesses of the carrier material are compensated for by moving the prestressed coating device towards or away, and thus the distance of the coating slot from the carrier material is kept constant even over long operating times becomes.
the schematic side view of a pneumatically or spring preloaded coating device 1 shown in FIG. 1 has a runner 4 near each of the two end faces of the coating device 1, which is designed as a sliding runner with a sliding coating 2.
the runners 4 rest on the outer surface of an application roller 3.
a pressure force F is exerted on the rear side of the coating device 1, as a result of which the runners 4 are pressed against the application roller 3 and be biased.
the two runners 4 are supported on the opposite surface line of the application roller 3.
Coating device 1 is, for example, a system with rollers running in the same or opposite directions, a slot nozzle or a sliding caster.
the coating device 1 applies a liquid layer to a band-shaped carrier material 9 which forms the coating web which is guided over the application roller 3.
the two runners 4, 4 are pivoted on the housing 13 (see FIG. 3) by means of pivots 7, 7.
the coating device 1 follows the relevant changes in the opposite surface line of the application roller 3, this surface line also being the contact line between the runners 4, 4 and the application roller 3.
the distance between the application roller 3 and the coating device 1 is kept constant, so that a coating gap 1 of the coating device 1 which is always parallel and accurate to the opposite surface line is guaranteed, and the sum error from individual errors, such as bearing play, out-of-roundness of the application roller, concentricity errors, shape errors of bearings and application roller 3 as well as pendulum and springs of the application roller 3 with different and changing tensile forces in the strip-shaped carrier material 9 to be coated is corrected by the respective descending of the coating device, thereby largely avoiding layer thickness differences in the coating.
the runners 4, 4 lie on the circumference of the application roller 3. However, it is also conceivable for the runners to rest on the outer edges of the carrier material 9 in the case of a smooth and abrasion-resistant carrier material which is being coated. This also makes it possible to correct differences in the thickness of the band-shaped carrier material 9. Regardless of whether the runners 4, 4 rest on the outer surface of the application roller 3 or on the outer edges of the band-shaped carrier material 9, they each serve as a spacer between the coating device 1 or the application unit of the coating device and the application roller 3.
the coating device 1 is moved along guides 6 which are arranged on both sides and which are fastened on a carrier 8. This movement is preferably carried out in an oscillating manner, but can also be strictly linear. During the oscillating movement, the coating device 1 is rotatably connected to the two guides 6 via a bearing on the two outer sides, as will be described in more detail later, so that the coating device 1 or the runners 4, 4 not only in the direction of the guides can perform a movement, but also a pendulum movement around the longitudinal direction of the guides. If the bearing is omitted, the coating device moves purely linearly along the guides.
FIGS. 2 and 3 The second embodiment of the invention shown schematically in FIGS. 2 and 3 is configured similarly to the first embodiment according to FIG.
the coating device 1 is additionally equipped with a fine adjustment 5 so that the height of the application, i.e. the slot nozzle or the sliding caster can be set very precisely or the application can be moved in very small steps.
each of the two guides 6 is seated on its own carrier 8.
a sliding bearing covering for dry running for example, can be used as the sliding covering 2 for the runners 4. This can receive a solid lubricating film, e.g. Grease, or with drip lubrication using oil.
a reduction in the frictional forces and cooling of the skids can be achieved in a manner not shown with the aid of compressed air or water or also by cooling the application roller 3, in particular in the sliding zones of the skids.
FIG. 4 shows various positions of the coating device 1 of the first embodiment of the invention according to FIG. 1 when bearing play and bearing errors of the removal roller 3 occur.
the runners 4, 4 can follow the occurring eccentricity of the application roller 3 and the rotation thereof by means of pendulum movements, as already mentioned above, around the guides 6, 6, which results in smooth transitions between the maximum deviations of the axis of the application roller 3 from the ideal axis direction is taken care of.
the spring force F on the housing of the coating device is exerted by prestressed compression springs 10, 10, which bear at one end against the rear of the coating device 1 and at the other ends against counter bearing 15.
the guides 6, 6 are easily movable, ball- or roller-mounted guides, along which the coating device 1 is displaceable or adjustable.
the coating device 1 is rotatably connected to the two guides 6, 6 via bearings 11 on the two outer sides, it also being necessary to ensure that lateral play permits the coating device 1 to be shifted on one side.
the prestressing of the coating device 1 acting on both sides due to the compression springs 10, 10 ensures that the coating device 1 constantly follows up against the application roller 3. In FIG.
the position of the coating device 1 and the application roller 3 is shown in full lines, with an ideal axial direction of the application roller. Deviations of the axis of the application roller 3 from the ideal axis direction are indicated with + A and -B. The different positions of the application roller 3 to the coating device 1 are shown in dashed lines when these deviations occur. So that the coating device 1 can follow the opposite surface of the application roller 3 when the application roller 3 rotates, or when the deviations + A or -B occur, the guides 6, 6 and the bearings 11, 11 provide a smooth arrangement for the movements of the Coating device 1 in the direction of + A or -B safely.
FIG. 5 schematically shows a third embodiment of the invention, in which so-called roller skids 12 are used instead of skids, each of which is equipped with two rollers 14, 14, which bear in pairs against two opposing surface lines of the application roller 3 or against the outer edges of the carrier material 9 guided over the application roller 3.
the roller skids 12, like the skids 4 are rotatably articulated on the housing of the coating device 1 via pivot pins 7.
the compressive force F is exerted, for example, by two pneumatic elements 16 instead of the compression springs.
These pneumatic elements 16 are, for example, low-friction bellows cylinders which are supported on the one hand on the counter bearing 15 and on the other hand against the rear of the housing of the coating device 1. It goes without saying that such pneumatic elements 16 and also roller skids 12 can be used instead of the compression springs 10 or the skids 4 in the first and second embodiment of the invention.
