Definitions

the invention relates to a method and an arrangement for cleaning a cylinder of a rotary printing press.
the invention is particularly suitable for cleaning blanket cylinders and impression cylinders as well as plate cylinders or forme cylinders, for example in a coating unit.
a method of this type is known from DE-AS 1 808 909 for cleaning a plate cylinder.
a roller which is in contact with the cylinder is driven at different peripheral speeds.
a washing device with a washing roller mounted in a swivel joint which has a control cam in the area of the grippers of the printing cylinder.
the washing roller attached to a pressure cylinder is lifted from the outer surface in an angular area so that it does not collide with the grippers.
the transport of excess detergent (including impurities) into the cylinder channel according to EP 0 548 500 A1 also has a disadvantageous effect on the print quality of the sheets of the subsequent print job.
the excess of detergent builds up in connection with impurities as sludge in the cylinder channel and especially on the cylinder channel edge arranged at the beginning in relation to the direction of rotation of the printing press.
the excess detergent unnecessarily increases the detergent consumption without improving the cleaning itself.
An uncontrolled supply of detergent can cause the washing device to float on the surface of the cylinder.
the object of the invention is to develop a method and an arrangement for controlled cleaning fluid guidance, in particular for biological-based detergents, such as, for example, vegetable oil esters, on a cylinder jacket surface which ensures effective cleaning and a relatively dry cylinder jacket surface at the end of the washing process.
biological-based detergents such as, for example, vegetable oil esters
the angle-dependent cleaning is suitable for plate cylinders, blanket cylinders, impression cylinders and forme cylinders, especially for painting equipment.
the method and the arrangement are also suitable for washing devices with washing rollers, such as, for example, a washing brush or a roller with a soft outer surface (rubber or textile cover) or with a washing cloth that is operatively connected to a pressure element. All control processes of the washing device take place at certain predetermined angular positions of the printing press or of the cylinder to be cleaned.
Another advantage of the angle-controlled cleaning is that the entry of detergent or water into the cylinder channel is prevented by uncontrolled spraying. This reduces the consumption of detergent and water in an environmentally friendly manner, since it is not necessary to clean the entire surface of the cylinder.
the speed of the cleaned cylinders is increased. This accelerates the drying of the cylinder surface. At the cylinder channel edges in particular, any droplets still present are thrown off by centrifugal force. This helps to reduce start-up waste.
the mode of action is as follows:
the cleaning process consists of a washing process and a drying process.
the washing device 2 is activated by spraying the washing roller with detergent.
the washing device 2 is placed in an angular position D on the first edge (beginning of the cylinder pit 4) on the blanket cylinder 6.
the washing roller of the washing device 2 remains in contact with its outer surface until an angular position A is reached.
the angular position A is due to the area from the end of the printing sheet (format-dependent) and the angular position B (second channel edge) ) of the cylinder pit 4 limited.
a cleaning fluid wedge 3 consisting of detergent and / or water forms.
the fluid wedge 3 is on the outer surface of the blanket cylinder 6 in a circular sector formed by the angular positions D and A in front of the washing roller brought forth.
the washing device with the washing roller 2 is switched off by the blanket cylinder 6 and the fluid wedge 3 is deposited on the remaining lateral surface in a circular sector formed by the angular positions A and B by the rotary movement of the blanket cylinder 6.
the blanket cylinder 6 constantly rotates during the washing process, the cylinder channel 4 also passing through the washing device 2, but without contact.
the washing roller is again sprayed with detergent, in the angular position D it is placed against the blanket cylinder 6, in the angular position A it is switched off and the fluid wedge 3 is repeatedly deposited in the circular sector formed by the angular positions A and B. .
This washing process can be carried out several times, with the blanket cylinder 6 and the water being able to be cleaned with water before or after the end of washing with detergent in the angular positions described is also deposited in the circular sector formed by angular positions A and B.
the washing roller of the washing device 2 is no longer sprayed with detergent or water, but preferably is constantly doctored off during its rotation.
the washing roller is again placed in the angular position D on the rotating blanket cylinder 6, remains on the angular position A in addition to the angular position B.
the deposited fluid detergent and Water
the washing roller can also remain parked in the circular sector, formed by the angular positions D, A, and can be placed on the lateral surface from the angular position A until the angular position B is reached, and thus only absorb the deposited fluid.
the rotating washing roller of the washing device 2 has a higher peripheral speed than the blanket cylinder 6.
the washing roller can maintain its direction of rotation in the circular segment of the angular positions A and B, or the washing roller is reversed in the direction of rotation. It is also possible to stop the washing roller from moving. This then acts on the outer surface of the rotating blanket cylinder 6 as a doctor.
the washing device is disengaged from the jacket surface in the area of the cylinder pit 4, so that essentially no sludge (detergent, water, paint / varnish residues, contaminants, dust) can be conveyed into the cylinder pit 4 and does not build up on the channel edge .
the washing device 2 does not have to be switched off in the angular position A (FIG. 3).
the fluid wedge 3 is brought upstream of the washing roller and deposited on the flat 5.
the washing roller of the washing device 2 is brought into contact with the flattened portion 5 approximately from the angular position A.
the deposited fluid 3 is taken up by the washing device 2.
the washing roller can also maintain its direction of rotation, stop it or reverse the movement. In the area of the cylinder pit 4, the washing device 2 is switched off from the blanket cylinder 6.
a double-size impression cylinder 1 according to FIG. 4 has two arc-carrying lateral surfaces I and II.
pre-moistening is carried out in an angular position C
the washing device 2 is switched on in the angular position D
the switch is set in the angular position A and the angular position B is switched off. Since there are two lateral surfaces I and II, for example the lateral surfaces I and II can be in contact with the washing device 2.
the washing device 2 is switched off from the lateral surface I.
the rotating washing roller of the washing device 2 is scraped off in the circular sector of the outer surface I and then placed on the outer surface II again. After cleaning the lateral surface II, the washing device 2 is also set against the lateral surface I. During the further rotation of the cylinder 1, the washing device 2 is turned off in the circular sector of the lateral surface II and the rotating washing roller is scraped off.
the outer surfaces I, II or further outer surfaces can be cleaned alternately. It is advantageous to scrape off the rotating washing roller in the parked position after at least one cylinder revolution. A relatively clean washing roller is thus always brought into contact with the cylinder jacket surface I and / or II to be cleaned.
