Definitions
- the invention relates to a method and a device for cleaning the surface of a preferably circular cylindrical rotating body which is driven in rotation about an axis. In particular, it is about cleaning the surface of a roller or cylinder, which can be part of a printing press.
- a rubber blanket cylinder is an example, since it places particularly high demands on the cleaning quality in order to achieve a good print image.
- the invention is not just about cleaning rollers and cylinders in printing presses.
- the material web the so-called printing material
- the application techniques are used as painting, coating, impregnating, sealing and. a. designated.
- JP 2000-6379 A From JP 2000-6379 A, the ultrasonic cleaning of a circular cylindrical rotating body driven in rotation about its axis is known. Bath cleaning is treated as prior art. In contrast, the further development of JP 2000-6379 A consists in rinsing the rotating body. Ultrasound is injected into the rinsing liquid.
- the object of the invention is to provide a method according to the preamble of claim 1 and a device according to the preamble of claim 7, with which the effectiveness of cleaning can be significantly improved, so that as a rule with water without the addition of a solvent Cleaning liquid needs, but the proportion of solvent can be significantly reduced, so that there are better working conditions, a lower risk of exposure to solvent vapors and a relief for the environment.
- the improved effectiveness of cleaning should result in a reduction in cleaning time and an increase in operating time between two cleaning processes, so that productivity is increased and costs are reduced.
- the cleaning cloth used in the invention is soaked in its Kon ⁇ contact region with the rotary body to be cleaned substantially to saturation with the cleaning liquid.
- ultrasound is emitted against the cloth.
- the cloth used according to the invention is really wet.
- the high liquid content of the cloth which is essentially saturated to the point of saturation, ensures good ultrasound conduction to the surface to be cleaned. A diffuse sound field is achieved through the cloth.
- Ultrasonic cleaning is widely used in industrial technology. Typically, ultrasound transmitters are located in a cleaning bath into which a part to be cleaned is placed. This requires machine downtime and removal and reinstallation of the part. •
- a rotating body is cleaned by means of ultrasound in the installed and operating position. Removing and reinstalling the rotating body is no longer necessary, and there are no machine downtimes.
- the physical effect of ultrasonic cleaning is based on cavitation in a liquid (cf. Kenneth S. Suslick, "The Chemical Effects of Ultrasound", Spectrum of Science, April 1989, pages 60 to 66).
- a special feature of the invention is the required liquid bring the rotating body in the installed and operating position and also use a cleaning cloth used for this as a diffuser for the ultrasound. phenomena such as absorption, reflection, diffraction, scattering and refraction of the sound waves, and transversal sound waves develop.
- the cleaning liquid is stowed in the contact area of the cloth with the rotating body.
- the contact area of the cloth with the rotating body is sealed down and to the side.
- a slide with seals is provided for sealing.
- intensity-modulated and / or frequency module values and / or pulsed ultrasound are used in a frequency band between 2 x 10 4 s "1 and 10 ⁇ s " 1 , preferably between 6 x 10 * s "1 and 10 5 s " ⁇ .
- the emitting surface of the ultrasound transmitter is coated with a soft material. Cavitation on the ultrasound transmitter is prevented by ultrasound reflected by the cloth.
- a transport mechanism is provided which unwinds the cloth from a clean cloth roll and winds it up to form a dirty cloth roll.
- FIG. 1 shows a device for cleaning the surface of a circular-cylindrical rotating body in a lateral sectional view transverse to its axis
- Fig. 2 shows details of the device in a schematic Thomasan- • looks parallel to the axis of the rotating body.
- the blanket cylinder 10 of a printing unit is shown in FIG. 1 as an example of a rotary body to be cleaned. As indicated by arrow 12, it rotates in one direction or another about its central axis.
- the cleaning cloth 14 is a fleece.
- the cleaning cloth 14 is unwound from a clean cloth roll 18 and deflected by a roller 20 towards the cylindrical surface 16. As indicated by the arrow 22, the roller 20 can be adjusted towards and away from the blanket cylinder 10.
- the cleaning cloth 14 is impregnated with cleaning liquid at a moistening station 24 immediately before reaching the cylindrical surface 16.
- the cleaning liquid is mostly pure water. Only in special cases can a small amount of solvent be added.
- FIG. 1 shows the feed line 26 of the humidification station 24, and FIG. 2 shows individual spray nozzles 28 of the humidification station 24 in a row.
- the moistening station 24 is designed to soak the cleaning cloth 14 until it is substantially saturated with the cleaning liquid.
- the cleaning cloth 14 comes in flat contact with the cylinder jacket 16 of the blanket cylinder 10 over a short circumferential segment.
- the angular length of the contact segment is limited by the limited space on a printing press.
- the cleaning cloth 14 leaves the cylinder jacket 16 of the blanket cylinder 10 via a slide 30 which, as indicated by the arrow 32, can be adjusted against the cylinder jacket 16 and away therefrom.
- the slider 30 has seals that cover the contact area of the cloth 14 seal with the cylinder jacket 16 downwards and to the side. Depending on the position of the slide 30, the contact area is more or less sealed off and the cleaning liquid is more or less stowed therein.
- the cleaning cloth 14 used is deflected on a roller 34 and wound up on a shaft 36 of the transport mechanism to form a roll of dirty cloth 38.
- the web feed of the cleaning cloth 14 is effected with the shaft drive.
- the tub 40 has a suitable level indicator and a drain.
- an ultrasound transmitter 44 is arranged, which is opposite the blanket cylinder 10 and emits ultrasound against the liquid-soaked cleaning cloth 14.
- the ultrasonic transmitter 44 has a box-shaped housing, the contact surface 46 of which is curved with the cleaning cloth 14 in accordance with the curvature of the blanket cylinder 10. As a result, a constant running gap for the cleaning cloth 14 is formed between the blanket cylinder 10 and the ultrasonic transmitter 44.
- the radiating surface of the ultrasonic transmitter 44 is coated with a soft material.
- the slide 30 stands on all sides of the housing of the ultrasonic transmitter 44 and seals it down and to the side.
- the ultrasonic transmitter 44 is isolated from the moistening station 24 and the slide 30 from structure-borne noise.
- a possible form of structure-borne sound insulation 50 to the side and 52 to the humidification station 24 and slide 30 is shown schematically in FIG. 2.
- the structure-borne noise-insulated unit can be moved towards and away from the blanket cylinder 10.
- the cleaning device described can be turned off as a complete unit from the blanket cylinder 10, so that the cleaning cloth 14 does not touch its outer surface 16. This is the normal printing position of the blanket cylinder 10, in which the cleaning unit is out of function and is in a standby position, not shown. If cleaning is required, the printing process is interrupted and the cleaning unit, as shown in FIG. 1, is brought up to the cylinder jacket 16 of the blanket cylinder 10.
- the cleaning process takes place with a cyclical path feed of the cleaning cloth 14.
- a new, clean web section of the cloth 14 repeatedly comes into contact with the surface of the blanket cylinder 10 to be cleaned.
- the cleaning process takes place when the cloth 14 is standing by rotating the blanket cylinder 10 about its axis.
- the humidification station 24 is also clocked.
- the cloth 14 can be brought to the surface of the blanket cylinder 10 both in the moistened and in the dry state in order to wipe it wet or to wipe it dry.
- the ultrasonic transmitter 44 is clocked accordingly. Ultrasound radiation only takes place if the cleaning cloth 14 is really wet in the contact area with the blanket cylinder 10, i. H. until is substantially saturated with the cleaning liquid.
- the essential novelty of the invention is the use of ultrasound technology for the direct cleaning of a rotationally driven, preferably circular-cylindrical body of revolution.
- liquid is required.
- a cleaning liquid is usually used. It is new to let the ultrasonic cleaning process run directly on the rotating body to be cleaned, and not, as usual, to transport the object to be cleaned to an ultrasonic cleaning system and to use ultrasound to clean it there in a tub or in a container filled with cleaning liquid , It is also new that the rotary body can be cleaned in a printing press or the like without solvents.
- Ultrasonic waves are usually generated by piezoelectric ultrasound transmitters. Depending on the orientation of the crystal, longitudinal or transverse waves can be excited. Depending on the setting or design of the pulse generator, ultrasound waves of different frequencies can be generated. B. 2 x 10 4 s "1 , 4.3 x 10 4 s " 1 or 8 x 10 4 s "1.
- the generator constantly changes certain parameters according to a predetermined control, so that the desired cleaning fluid in the excited
- the control sequence also depends on the nature of the cleaning cloth 14. The latter has a damping effect and it generates a diffuse sound field.
- the invention enables the direct cleaning of rollers and cylinders in the installed state, for example in a printing press, by using ultrasound technology.
- An advantage of the invention is that the Cleaning, depending on the paper and the color used, can usually be done without the use of solvents. The harmful health effects for personnel resulting from solvent vapors is thus eliminated or considerably reduced.
- the possibility, for example, of working on a web-fed rotary printing press without solvent means that there is no longer any danger of explosion in the dryer area due to the solvent residues which could get into the dryer by train.
- the direct cleaning with ultrasound is very thorough. The time interval between cleaning processes can be increased considerably depending on the paper and the color used.
