Definitions

the invention relates to an arrangement for dosing according to the preamble of claim 1.
the dosing device according to the invention uses a so-called doctor blade in coating systems, this doctor blade being a feed device for the coating compound directly or at a distance of perhaps 30-50 cm along the circumference of the web Paper or cardboard leading roller can be assigned. It may also be the case that the paper web only runs onto the roller later, so that firstly the bare roller shell is coated and the coating slip is only transferred later from the roller shell to the paper web.
a generic device is known from EP-A 04 26 980.
this application e.g. also describes a measuring device with a transmitter which emits light which is emitted by a light-sensitive receiver arrangement, e.g. is registered in the form of a diode array or a CCD camera. The output signal of these arrangements is then processed to adjust the angular position of the blade with respect to the circumference of the roller at the point of contact of the blade thereon. All measuring devices described in this application, despite their miniature design, are still relatively large and have a weight that is not to be neglected.
the object of the invention is to provide such a measuring device in which a sensor with a noticeable weight is avoided. Another object is also to design the measuring device in such a way that the blade, including the measured value transmission devices, can be changed quickly.
the doctor blade Due to the light-sensitive layer on the blade, which sends the light reflected by a transmitter onto this light according to the known law of reflection to a receiver, the doctor blade is only locally loaded by negligible additional weights, and a quick change is possible. If a reflection strip is used, it can be applied to the blade before it is installed. If a mirror plate is used as the reflecting layer of the blade, favorable angles of incidence and reflection of the measuring beams can be achieved by the carrier of the mirror surface being wedge-shaped. The carrier may also be magnetic so that it can be quickly attached to and removed from the blade.
a non-contact arrangement on an inductive or capacitive or ultrasound basis is also possible, the sensor being arranged at a certain distance from the pressure bar or the clamping of the blade, so that the distance between the blade and the sensor in this area and taking into account the contact pressure of the blade, the angle of the blade can be calculated.
the doctor blade 2 is clamped in the jaws 3 and 4 of a holder and is pressed against the counter roller R by means of a pressure bar 5, which is held displaceably between guide plates 21 and 29 according to the double arrow.
a transmitter for light in particular laser light 9, is provided, which sends a light beam 12 onto a light reflection layer 8 ', from where the reflected beam 13 reaches the receiver 10 in the form of a CCD arrangement with a spread angle ⁇ .
the reflection layer 8 ' here is a mirror layer of a mirror plate 6, which is detachably attached to the doctor blade by means of a magnetic carrier plate 7 (since the doctor blade is known to consist of magnetizable steel).
the carrier plate 7 is wedge-shaped with an angle c in order to obtain a favorable course of the incident beam 12 and the reflection beam 13. This gives you enough space to be able to attach the transmitter 9 and the receiver 10 in the vicinity of the doctor blade in a favorable manner.
the reflection layer 8 can also be applied to a film that can be glued to the doctor blade 2 or - designed as a magnetic film - can simply be placed on the doctor blade. You can use a strip of e.g. Use a length of 5 cm and attach it to the right place before installing the doctor blade. This minimizes the downtime of the coating system when changing the coating blade.
the signal from the receiver 10 is then sent to a control device, not shown here, in order to be able to adjust the angle of the doctor blade.
a control device not shown here
the actual coating edge (chamfer f) at the blade end also runs in relation to the counter roller R or the paper web guided by it.
the chamfer f should run exactly tangential to the counter roller and paper web.
the paper web or roller R runs past the doctor blade at the speed v in accordance with the arrow shown.
