    BE S CHARGING DEVICE
    FIELD OF THE INVENTION
    The invention relates to a device for applying a coating to a plate-shaped object, in particular a glass plate, comprising a first platform and a rotatably mounted on the first platform roller for applying coating material to the plate-shaped object.
    STATE OF THE ART
    Such coating devices are used for applying color esp. On plates (glass panels, prefabricated facade elements, shower walls, full-scale railing parts, etc.). The roller may have a smooth surface for full-surface application of paint or a structured surface for printing a coating pattern, in the form of a (e.g., repeating) pattern.
    The disadvantage of coating devices known in the prior art is, in particular, that the coating quality (coverage, layer thickness, etc.) does not remain constant over the plate surface. There are variations not only within one plate, but also from plate to plate, which is why the required reproducibility in such inking rollers is not given.
    OBJECT OF THE INVENTION
    The aim of the present invention is to provide a coating or printing device that does not have this disadvantage and in which a constant coating quality and high reproducibility can be achieved. Preferably, this goal should be achieved with simple and inexpensive, but at the same time reliable and durable means.
    PRESENTATION OF THE INVENTION
    This object is achieved with a coating device mentioned in the introduction in that the device comprises: a second platform supporting the first platform, at least one force and / or pressure transducer, which preferably cooperates with the first platform and / or the second platform, and an adjusting device for setting the first platform relative to the second platform as a function of the measured values of the force and / or pressure transducer or for adjusting a receptacle for the plate-shaped object relative to the first platform as a function of the measured values of the force and / or pressure transducer.
    The idea underlying the invention is to keep the effect of the roller on the plate-shaped object as constant as possible. The print quality depends essentially on the force or pressure exerted by the roller on the plate-shaped object. This effect of the roll is detected according to the invention by means of a force and / or pressure transducer (i.e., a sensor). By means of the adjusting device is now ensured that the effect of the roller is kept as constant as possible on the plate-shaped object.
    This can be done by causing the actuator to (at least slightly) shift the two platforms relative to each other if a deviation from the controlled variable (e.g., predetermined force / pressure) is detected. In this embodiment, the first platform relative to the second platform by the adjusting device (at least slightly) displaceable or at least bendable. The first platform is moved at too high pressure from the receptacle or from the plate-shaped object arranged thereon and moved or pressed at too low pressure on the receptacle or the plate-shaped object. In an alternative embodiment, the actuator is configured to cause displacement of the receptacle (carrying the plate-shaped article) relative to the first platform (carrying the roller).
    The term "adjustment" by means of the adjusting means comprises both the possibility of a relative movement, which leads to a (significant) change in the gap between the roller and plate-shaped object, as well as the possibility of a mere change in pressure (ie substantially without noticeable change of the gap, if this already vanishingly small).
    The term "platform" is to be seen broadly within the meaning of the invention and may esp. A carrier, a frame, a frame, a scaffold, a holder, a receptacle, etc. be.
    The roller may have a smooth surface for full-area application of paint or a textured surface (in the form of, for example, a recurring pattern) for printing a coating pattern.
    The term "coating" or "coating material" basically means any means that can be applied by means of a roller to the surface of an object, especially paint, adhesives, means for (previous) surface treatment or (subsequent) surface refinement, etc.
    It should be mentioned at this point that the device according to the invention can also be referred to as a printing device or printing press.
    The receptacle for the plate-shaped article may e.g. a support, a table, a conveyor, a holder, etc. be.
    Instead of only one force and / or pressure transducer, two or more may be provided. In this case, the measured values of all transducers (sensors) can be taken into account for the setting process by the adjusting device. Preferred is e.g. if a plurality of transducers are arranged distributed in a direction parallel to the axis of rotation of the roller and thus conclusions can be drawn on the force / pressure curve along the axis of rotation of the roller. With appropriate design of the actuator, e.g. with at least two actuators, thus pressure differences along the roller can be compensated.
    A preferred embodiment is characterized in that the adjusting device comprises a control device which is connected to the output of the force and / or pressure transducer, and at least one drive connected to the control device, in particular a spindle drive, for relatively moving the first platform to the second platform or (for relative movement) of the recording to the first platform comprises. As a result, undesired deviations from a controlled variable (for example, predetermined pressure of the roller on the plate-shaped object) can be effected automatically and directly.
    A preferred embodiment is characterized in that the force and / or pressure transducer in a
    Force flow, preferably in the main power flow, between the roller and the second platform is arranged. It has been found that by this measure deviations from a controlled variable and related quality impairments can be reliably detected and still at an early stage, whereby the coating quality can be significantly increased.
    A preferred embodiment is characterized in that the force and / or pressure transducer is connected between the first platform and the second platform. The measurement is thereby displaced to a location which is no longer directly in the area of the coating process (roller), but at the same time provides reliable measurements relating to the effect of the roller on the object to be printed.
    A preferred embodiment is characterized in that the measured value of the force and / or pressure transducer is a direct or indirect measure of a force or pressure transmitted by the roller to the plate-shaped object. This can be used directly to (expected) quality impairments.
    A preferred embodiment is characterized in that the force and / or pressure transducer is designed in the form of a load cell with opposed force introduction interfaces. One of the force introduction interfaces with the first platform and the other is preferred
    Force introduction interface coupled to the second platform. In addition, this embodiment allows the use of inexpensive and commercially available pickup.
    A preferred embodiment is characterized in that the force and / or pressure transducer comprises at least one strain gauge and / or at least one piezoelectric element.
    A preferred embodiment is characterized in that the first platform is arranged below the second platform and the force and / or pressure transducer is arranged above the roller, preferably in the vertical, which passes through the axis of rotation of the roller. Such a hanging arrangement is advantageous since the (glass) plates to be printed only have to be placed on the receptacle, while the roller "hangs down" from above and can be moved (pressed) upwards and downwards by means of adjusting means.
    A preferred embodiment is characterized in that the actuator is arranged above the roller. This results in an immediate (compensation) effect that provides optimal coating results.
    In a preferred embodiment, in addition to and in parallel with the roller, the
    Applying coating material to the plate-shaped object, at least one doctor roller (or metering roller) is provided, with which the coating material (in particular color) is pressed or transferred onto the application roller. This doctor roller is preferably also rotatably mounted on the first platform.
    The object is also achieved with a method for applying a coating to a plate-shaped object, in particular a glass plate, with a device according to the invention wherein, depending on measured values acquired with the force and / or pressure transducer, by means of the adjusting device, an adjustment of the first platform relative to the second Platform or recording takes place relative to the first platform.
    BRIEF DESCRIPTION OF THE FIGURES
    In a preferred embodiment, the measured values acquired by the force and / or pressure transducer are stored and evaluated. By means of such an evaluation, (recurring) causes of undesired deviations of the roller pressure from an ideal value can be determined and subsequently corrected.
    In the following, a preferred embodiment of the invention will be described in more detail with reference to the drawing. It shows
    1 shows a coating or printing device according to the invention,
    2 shows an actuating device in a schematic representation,
    Fig. 3 shows an embodiment of a force or pressure transducer, and
    4 shows an embodiment of the coating device.
    WAYS FOR CARRYING OUT THE INVENTION
    1 shows a coating or printing device 10 for applying a coating to a plate-shaped article 9, in particular a glass plate. The device 10 comprises a first platform 1, a roller 3 rotatably mounted on the first platform 1 for applying coating material (in particular paint) to the plate-shaped object 9, and a receptacle 14 for the plate-shaped object 9 (here in the form of a support or support) a table).
    The first platform 1 is arranged in the illustrated embodiment below a second platform 2 and is supported by this. The first platform 1 is mounted on the second platform 2 via a guide 13 and can be displaced or pressed relative to the second platform 2 at least slightly (here: upwards or downwards).
    The second platform 2 may be arranged along a rail (not shown), e.g. mounted on the ceiling, be moved horizontally to print the object 9. Alternatively, the receptacle 14 could be part of a conveyor which moves the article 9 under the roller 3.
    As can be seen from FIG. 1, a doctor roller 8 can also be provided which is parallel to the (application) roller 3 and is also rotatably mounted on the first platform 1.
    A force and / or pressure transducer 4 connected between the platforms 1, 2 (i.e., cooperating with both platforms) serves to monitor the action of the roller 3 on the object 9 to be printed.
    The device 10 further comprises an adjusting device 5 for adjusting the first platform 1 relative to the second platform 2 as a function of the measured values of the force and / or pressure transducer 4. In an alternative (not shown) embodiment, the adjusting device could be designed such that it the receptacle 14 cooperates and causes an adjustment of the receptacle 14 relative to the first platform 1.
    The adjusting device 5 comprises (FIG. 2) a control device 6, which is connected to the output 11 (FIG. 3) of the force and / or pressure transducer 4, and a drive 7, in particular a spindle drive, connected to the control device 6 for relative movement the first platform 1 to the second platform 2 (or - as already mentioned above - for relative movement of the receptacle 14 to the first platform 1).
    In the illustrated embodiment, the force and / or pressure transducer 4 above the roller 3 - here even in the vertical, which goes through the axis of rotation of the roller 3 - arranged. Likewise, the actuator 7 of the adjusting device 5 is arranged above the roller 3.
    The force and / or pressure transducer 4 is preferably arranged in a force flow (here: in the main power flow) between the roller 3 and the second platform 2. It is particularly preferred if (as in the illustrated embodiment) the measured value of the force and / or pressure transducer 4 is a direct or indirect measure of a force or pressure transmitted by the roller 3 to the plate-shaped article 9.
    According to FIG. 3, the force and / or pressure transducer 4 can be designed in the form of a load cell with opposed force introduction interfaces 12. The force and / or pressure transducer 4 may e.g. comprise at least one strain gauge and / or at least one piezoelectric element.
    In the method for applying a coating to a plate-shaped article 9, in particular a glass plate, with a device 10 is thus carried out depending on measured with the force and / or pressure transducer 4 measured values and by means of the adjusting device 5, an adjustment of the first platform 1 relative to the second Platform 2 (or just alternatively: an adjustment of the receptacle 14 relative to the first platform 1).
    Finally, FIG. 4 shows an embodiment of a coating device 10, in which the second platform 2 is movably mounted on a table. In such a standing embodiment, the platform 2 is placed on the table or is supported by this. The platform 2 may be e.g. be moved along a rail or guide (in Fig. 4 from right to left).
    As already mentioned in connection with Fig. 1, the coating apparatus 10 can alternatively also be in a suspended design (or portal design) in which the second platform 2 is suspended (for example from a rail running on the ceiling). The principle according to the invention can be implemented independently of the respective embodiment.
    The invention is not limited to the described embodiments and the aspects highlighted therein. Rather, within the concept of the invention a variety of modifications are possible, which are within the scope of expert action. It is also possible, by combining the means and features mentioned to realize further embodiments, without departing from the scope of the invention.
