Definitions
- the invention relates to a device for applying paint to a web with a stencil and a squeegee for pressing the color through the stencil onto the web, the squeegee - preferably over its entire length - is rotatably guided in a tunnel of a guide body, the Roller squeegee protrudes over the tunnel with a part of its circumferential surface in a longitudinal slot facing the template.
- roller squeegee can be inserted substantially loosely in the circular stencil, its guidance being achieved only by running against a support bar parallel to the roller squeegee while being arranged by one under the printing blanket Magnet is pressed against the inside of the template.
- the object of the invention is to provide a device of the type mentioned with an improved storage for the doctor blade, so that it remains rotatable even when using highly viscous paints, ink jams are avoided and a precise mechanical guidance of the doctor blade is possible.
- the tunnel wall is designed such that it only bears on a plurality of guide points spaced apart in the longitudinal direction of the tunnel on the outside of the doctor blade, while it runs at a distance from the doctor blade between these guide points.
- a tunnel-like guide which surrounds the roll more than half its diameter, is preferably provided, which provides permanent protection of the roll against bending and easily damaged surface.
- the The tunnel wall is designed in a design that guarantees the application function, in particular the theological behavior of the color pastes in all color families and their viscosities, a uniform and after the application taking place in / on the stencil, a drop-free stencil field after the application.
- the roller guide in the tunnel is a rib sequence which is adapted to the roller diameter, the ribs being able to be at a distance of one roller diameter over the length of the tunnel.
- the roll is stored in the ribbed tunnel with minimal play, so it runs smoothly.
- the tunnel body is preferably made of a slidable plastic, while the application roller consists of a magnetically active material that can be provided with a material that hardens the surface, for example hard chrome.
- the guide body with the tunnel and the doctor blade are inseparable in normal use. Nevertheless, the unit consisting of the guide body and roller doctor blade can advantageously be designed to be removable for the exchange thereof. Despite the intimate keeping of the doctor blade in the tunnel, it is easy to clean the tunnel and doctor blade without removing them.
- the depressions in the inner wall of the tunnel allow an excellent overall washing of this tunnel squeegee unit.
- the paint cushions located there can be flushed out, for example, by a water jet from a nozzle (water pressure above 10 b).
- the guide part with the tunnel can be opposite Ink tube, to which it is advantageously fastened, can be supported in a height-adjustable manner by means of an automatically working height adjustment, so that there is a self-alignment of the roller doctor blade.
- the roller doctor blade is therefore functionally independent of the ink production. This represents an advantage over known guide devices, which still require precise adjustment, because otherwise problems with the doctor roll will result.
- the tunnel is suspended so that it can move in the vertical direction. It is possible to change the roll diameter, but this can be done in a short time. Typical smallest roll diameters are of the order of 6 mm, the larger roll diameters are 25 mm, of course other roll diameters are also possible.
- the roller doctor blade itself can have a smooth cylindrical outer surface, but also a corded outer surface.
- the tunnel can be designed as a replaceable wear element.
- FIG. 1 shows a paint tube of a device according to the invention together with a side view of a roller doctor guided in a tunnel
- FIGS. 2a, 2b and 2c show sections according to line A-A of FIG. 1 with different
- FIG. 3 shows a cross section through the guide body and the doctor blade in the area of the guide points on the outside of the roller doctor blade
- the Fig. 4 shows a parallel section, but between two guide points where the tunnel wall
- one 5 shows a perspective illustration of the end section of a guide body with a roll doctor incorporated therein
- FIG. 6 shows the insertion of the roll doctor into the guide body of another exemplary embodiment
- FIG. 7 shows a bottom view of this exemplary embodiment
- Fig. 1 shows a conventional paint tube for supplying the paint inside a
- Rotation template which is not shown here for the sake of clarity.
- the paint emerges from the paint tube on the inside of the rotary stencil and is there from the squeegee
- the doctor blade 2 in the tunnel of a guide body 3 in is essentially rotatable over its entire length.
- the guide body 3 together with the doctor blade 2 essentially forms a unit which is mounted on the color tube 1 so as to be vertically movable in the direction of the double arrow.
- the sections AA of FIG. 1 according to FIGS. 2a, 2b and 2c show the ink tube 1 and the squeegee 2 rotatably mounted in the tunnel 5 of the guide body 3.
- This squeegee 2 is located on the inside of a circular stencil arranged between the web 7 and the squeegee 2 and presses the color through the circular stencil onto the web 7.
- the doctor blade 2 is attracted in a manner known per se by an underlying magnet 8 during printing.
- the guide body 3 together with the squeegee 2 is mounted on the ink tube 1 so that it can move in height, so that no exact adjustment of the same is necessary in order to ensure that the squeegee 2 lies precisely against the inside of the circular stencil.
- This height adjustment is realized in that the guide body 3 for the roller squeegee 2 is attached to a slide 6 which is slidably mounted in a receptacle 9 which is fixed to the paint tube.
- the tunnel 5 inside the guide body which is preferably made of plastic, does not have a constant cross section over the entire length, while the metallic roller doctor 2 does. It is cylindrical (in special cases also corded).
- the guide body rests only on certain guide points or ribs 10 on the doctor blade 2, while just next to it between two such guide points 10 there is a distance d from the doctor blade 2.
- the tunnel between the doctor blade 5 and the tunnel wall 5a of the guide body 3 has an exemption that allows the ink cushion to penetrate. This measure reduces the friction between the doctor blade and the guide body, so that the doctor blade rotates well.
- the guide body forms an excellent guide over the entire length of the roller doctor because the support points or guide points 10 can be arranged at a small distance from one another, for example between 6 mm and 25 mm.
- the distance between the tunnel wall and the doctor blade 2 between these support or guide points 10 is preferably between 0.5 mm and 3 mm.
- the guide body 3 having the tunnel 5 is preferably formed in one piece from plastic and encloses the roller doctor blade overall over an angular range of over 180 °, as shown for example in FIG. 4. So that the doctor blade 2 can not go down fall out but nevertheless protrude according to the invention from the guide body 3 in the direction of the stencil in order to fulfill its roller doctor function and to be able to press the ink through the stencil.
- the storage of the doctor blade 2 in the tunnel 5 of the guide body 3 can also be seen from the perspective view of FIG. 5.
- the guide points 10 are designed as rib-like projections of the tunnel wall, each of which lies linearly against the outer wall of the doctor blade 2. Between these guide points, the tunnel wall has concave indentations 11, so that there is a distance between the tunnel wall and the outside of the doctor blade 2.
- the guide body 3 is round in its outer shape.
- the tunnel design and the doctor blade 2 correspond to the previous figures.
