Definitions
- the invention relates to a flexographic printing machine with an anilox roller, the Roller body axially from one held at one end in the machine frame Axle (22) is removable.
- anilox rollers serve to print the printing ink from one Take up the doctor blade and roll it onto a roller that runs around the circumference of the anilox roller Transfer cylinder.
- anilox rollers are usually formed by a metal cylinder having a ceramic layer on its peripheral surface carries a fine grid in the outer surface with the help of a laser Shallow cups were formed when passing through the chamber doctor blade filled with ink and then the ink to the printing cylinder submit.
- the bearing construction has so far been formed by stub axles, which in are integrally formed at both ends of the metal cylinder.
- the outside diameter of the printing cylinder is of the desired printing length dependent.
- the diameter of the anilox roller is not of the desired printing length dependent and is generally smaller than the diameter of the impression cylinder.
- different jobs are often different Anilox rollers are used, which differ in the nature of the cell grid differ. Therefore, the anilox roller of the be replaced more often.
- From US-A-5 370 047 is a flexographic printing machine of the type mentioned known in which the anilox roller two coaxial, arranged at a radial distance Has sleeves made of metal on the bearing for rotatable mounting of the anilox roller are trained in the machine frame.
- the inner sleeve is made by a continuous, rotatably held in the machine frame axis.
- Printing cylinders are often designed as hollow cylinders closed at both ends, which are traversed by a continuous axis and hydraulically are clamped on the axis (US-A 3 378 902).
- an anilox roller which consists of a sleeve Carbon fiber composite material is formed with a framework of carbon fibers and either at both ends with trunnions or inside with ball bearings is provided for rotatable mounting on a shaft.
- EP-A-1010522 a robot is replaced the cylinder of a printing press described. Through this robot, not only for changing the impression cylinder, but also for changing the Anilox roller can be used, the cylinder to be replaced is only on one end held like a boom. If the web of the substrate to be printed has a very large width and the printing cylinder accordingly and the anilox roller must be very long, step on the holding mechanism high mechanical loads on the robot. That's why it is desirable to reduce the weight of the anilox roller as much as possible.
- the object of the invention is therefore to provide a flexographic printing machine whose Anilox roller with the given mechanical strength as low as possible Has weight.
- This task is performed in a flexographic printing machine of the type mentioned solved in that the axis is rotatably mounted in the machine frame, and that the roller body has a cylindrical sleeve made of carbon fiber-containing material, which surrounds the axis at a distance and at both ends by discs is completed, which are releasably clamped on the axis.
- the roller body is formed by a sleeve made of carbon fiber material, for example a carbon fiber composite material with a wound framework made of carbon fibers in a plastic matrix.
- the carbon fibers give the Despite the low weight, the roller has sufficient strength so that it is the axis "self-supporting" can surround.
- the roller body is closed at both ends by discs, which too can be offset somewhat axially inward, and that with its inner peripheral edge can be clamped on the axis.
- the discs can be in one Be formed with the roll body, but can optionally separately from the roller body and made of another material and then be connected to the roller body in a rotationally fixed manner.
- the only drawing figure shows a partially broken side view of a Screen roller.
- the anilox roller 10 has a roller body 12 in the form of a tubular Sleeve made of a carbon fiber composite material.
- a tubular body made of carbon fiber composite material have been used for example as web guide rollers in Printing machines or possibly also as printing cylinders for smaller ones Print lengths used.
- These tubular bodies typically have a scaffold diagonally wrapped carbon fibers embedded in a plastic matrix are.
- the roller body 12 is closed off in the region of both ends by disks 14, which are made of metal in the example shown and rotatably with the Roller body are connected.
- the roller body 12 carries a metallic one on its outer peripheral surface
- Primer layer 16 made by metallizing the carbon fiber composite material can be formed.
- a ceramic layer is on the primer layer 16 18 applied, in the outer surface in a known manner a fine Grid from well 20 is formed.
- the disks 14 are penetrated by a continuous axis 22 made of metal, whose outside diameter is significantly smaller than the inside diameter of the cylindrical roller body 12. Between the axis 22 and the roller body 12 an annular cavity 24 is thus formed. Because of this design and due to the low weight of the roller body 12, the total weight the anilox roller considerably reduced, so that even relatively long anilox rollers easily handled for printing widths of 2000 mm or more can be.
- the axis 24 forms bearing sections 26, 28 at both ends.
- the bearing section 26 is stable by two bearings 30 in the machine frame 32 of the flexographic printing machine held while the bearing section 28 by a not shown removable bearing is held. After removing this bearing you can pull the roller body 12 with the disks 14 axially from the axis 22.
- the axis 22 forms a stop 34 for one of the disks 14, which rotatably with the axle is wedged.
- the washer 14 is on the removable bearing side releasably clamped on the axis 22 with a clamping bush 36.
