Definitions

the invention relates to a cleaning device on rotary printing presses for cleaning the outer surface of cylinders, with a pressure bar for pressing a cleaning cloth against the outer surface, with adjusting means for positioning the pressure bar and with an elastic profile rail over which the cleaning cloth is guided and over the cylinder width to the Lateral surface is pressed.
the object is achieved in that pneumatic cylinders are provided as actuating means, that the contact pressure on the profile rail takes place via spring elements which are supported on the pressure bar, and that a spring bar is provided between the spring elements and the profile rail for uniform power transmission.
This solution not only achieves a vibration-free contact of the profile rail on the outer surface, but also a compensation of unevenness in the outer surface is guaranteed.
the Female connector reaches a uniform contact pressure of the profile rail, so that an optimal cleaning result is achieved over the entire length of the cylinder.
An advantageous embodiment of the invention is characterized in that the spring elements are designed as compression springs with spring bolts and are adjustable via adjusting nuts. With this solution, a uniform contact force can be achieved over the entire length of the cylinder.
the female connector is fastened to the spring bolts and designed as a steel band, and the profile rail is interchangeably mounted on the steel band.
the steel band stabilizes the profile rail which, for. B. can be made of a rubber-like material. In addition, it transfers the contact forces very evenly and also enables easy replacement of the profile rail.
the cleaning device 1 can be adjusted on a printing cylinder 2 or by pivoting in its holder 4 on a blanket cylinder 3.
the holder 4 is provided on both sides between the machine side frames and enables the cleaning device 1 to be removed.
a pressure bar 6 is provided, which extends over the cylinder length.
the pressure bar 6 is pivotally mounted on both sides via pivot pin 7 on the support frame 5.
the pressure bar 6 receives a plurality of spring bolts 8 over its length, which are guided in guide bodies 10. Compression springs 11 act on the guide body 10, so that the profile rail 12 is resiliently supported via the guide body 10. The cleaning cloth 13 is guided over the profile rail 12.
the nuts 14 on the spring bolts 8 allow adjustment of the spring travel and limit the spring travel when they are in contact with the pressure bar 6 (FIG. 2). In the pressed state of the profile rail 12 on the lateral surface of the cylinder 2, 3, the nuts 14 are slightly raised from the pressure bar 6.
swivel levers 15 can be fastened on both sides, by means of which the profile rail 12 can be adjusted against the lateral surface 16 of the cylinder 2.
Cam rollers 17 are arranged on the swivel levers 15, which cooperate with cam segments 18.
Pneumatic cylinders 19 are attached to the support frame 5, the piston rods 20 of which press the pressure bar 6 downward about the pivot pin 7 when pressure medium is applied via rollers 21.
the rollers 21 are fastened to the pressure bar 6 via roller pins 22. If the overpressure in the pneumatic cylinder 19 is switched off, the pressure bar 6 is raised by tension springs 23, so that the profile rail 12 with the cleaning cloth 13 is lifted off the outer surface 16.
the tension springs 23 are arranged between pin 24 on the support frame 5 and pin 25 on the pressure bar 6.
threaded bolts 26 are provided on the pressure bar Wear adjusting nuts 27, the adjusting nuts 27 resting on the support frame 5 in the position shown in FIG.
a spring strip 9 is fastened to them, which extends over the length of the profile rail 12 and thus over the length of the cylinder jacket surface 16.
the female connector 9 can be formed as a steel band and at the same time serves as a bearing for the profile rail 12.
the profile rail 12 can be pushed in the longitudinal direction onto the female connector 9, so that the profit rail 12 can be easily replaced.
