- the CI rotates in direction of the arrow A in Fig. 1 , and a web 18 of a printing medium is passed around the CI, so that successive colour separation images can be printed thereon with the printing cylinders 14 of the various colour decks.
- a cleaning device 20 for cleaning the peripheral surface of the CI 10 is disposed in a working position directly above the top summit of the CI.
- the cleaning device 20 is supported on a transport mechanism 22, e.g. a belt drive, so that it can be moved (horizontally) to a rest position (shown in phantom lines in Fig. 1 ) in which it does not interfere with the web 18.
- the web 18 is removed, the cleaning device 20 is driven to the working position, and the CI 10 is driven with appropriate speed in the direction of the arrow A, so that the peripheral surface can be cleaned with the cleaning device.
- the cleaning device 20 comprises a body 24 which extends in axial direction of the CI 10 over practically the entire width thereof and defines a plenum chamber 26 that is open towards the peripheral surface 28 of the CI 10.
- the plenum chamber 26 is delimited by an elastic doctor blade or wiper 30 that engages the surface 28 of the CI with its lower edge.
- the plenum chamber 26 is delimited by a baffle 32 that forms a narrow gap with the surface 28 of the CI.

- a cleaning liquid e.g. water or a solvent
- the body 24 further includes an air supply line 40 connected to a compressed air source 42 and communicating with a number of air nozzles 44 for jetting compressed air onto the surface 28 of the CI inside the plenum chamber 26.
- the plenum chamber 26 is further connected to a suction line 46 that is connected to a suction blower 48 via a liquid separator 50, so that both, air and liquid may be sucked-off from the plenum chamber 26 and the surface 28 of the CI.
- the liquid supply unit 36, the compressed air source 42 and the blower 48 are controlled by an electronic control unit 52 which may also control a drive motor for the transport mechanism 22 shown in Fig. 1 .
- the liquid nozzles 38 and the air nozzles 44 are arranged alternatingly in longitudinal direction of the plenum chamber 26, and the height of the plenum chamber, as measured in the direction normal to the surface 28 of the CI, increases gradually from the axial ends towards the central portion where the suction line 46 is connected to the plenum chamber.
- the blower 48 When the cleaning device 20 has been brought into the working position and a cleaning process is to be started, the blower 48 is activated, so that air is withdrawn from the plenum chamber 26. This air will be replaced by ambient air that will mainly enter through the gap formed between the surface 28 of the CI and the lower edge of the baffle 32. As a result, an air current will pass over the surface 28 below the baffle 32 with relatively high velocity, so that dust and other contaminants will be removed from the surface 28 and sucked off.

- the liquid supply unit 36 is activated, and the cleaning liquid is jetted onto the surface 28 of the CI via the nozzles 38.
- the liquid On the upstream side, as viewed in direction of rotation of the CI, the liquid is prevented from leaking through the gap formed by the baffle 32, because the counterstream of air entering into the plenum chamber will drive the liquid back into the plenum chamber.
- frictional forces between the liquid and the surface 28 of the rotating CI will force the liquid towards the wiper 30. Since this wiper 30 is in elastic contact with the surface 28 of the CI, the liquid will be wiped off and retained in the plenum chamber 26, from where it is sucked away through the suction line 46. The liquid will then be collected in the liquid separator 50 from where it may be recirculated.
- a surge 54 of cleaning liquid will develop inside the plenum chamber 26 in front of the wiper 30, and the amount of liquid in this surge will be determined by an equilibrium between the supply of liquid via the nozzles 38 and the liquid sucked off through the suction line 46.
- any contaminants adhering to that surface will be dissolved in and/or washed away be the cleaning liquid and sucked off through the suction line 46, so that the entire peripheral surface 28 of the CI will be cleaned very efficiently.
- the length of a CI is slightly larger than the length of the body 24 of the cleaning device, and elastic seals 56 are provided for closing the gaps between the CI and the end walls of the plenum chamber 26. It will be understood that the length of the cleaning device is larger than the width of the web 18, so that the entire part of the surface 28 of the CI that is involved in the print process will be cleaned.
- the liquid source 36 will be switched off, and the compressed air source 42 will be activated instead, so that the liquid contained in the surge 54 will be sucked off and then the surface 28 of the CI will be blown dry by means of the compressed air jetted out through the nozzles 44.
- the blower 48 is kept operating, and its displacement will be larger than the supply of compressed air, so that ambient air is still being sucked-in below the baffle 32, so that no dirt that might still be present within the plenum chamber 26 will be blown out onto the clean surface of the CI. In this way, the surface of the CI will be thoroughly cleaned and dried, until finally, the cleaning device is moved back into its rest position, so that a new print run can be started.
- the height profile of the plenum chamber 26 that is shown in Fig. 3 has the effect that the current of compressed air passing over the CI surface 28 towards the suction line 46 will have an essentially uniform intensity over the entire length of the cleaning device, so that an essentially uniform cleaning and drying action is achieved.
- the phases in which liquid and compressed air are supplied may overlap, so that the cleaning effect is intensified by the combined action of liquid and compressed air.

Abstract
Description
- The invention relates to a cleaning device for a cylinder of a rotary printing press and to a rotary printing press equipped with such a cleaning device. More particularly, the invention relates to a device for cleaning the peripheral surface of a central back pressure cylinder of a printing press having a plurality of colour decks arranged along the peripheral surface of the back pressure cylinder.
- It is an object of the invention to provide a cleaning device that permits to rapidly and efficiently clean the surface of the cylinder so as to remove dust and other contaminants therefrom.
- According to the invention, this object is achieved by a cleaning device for a cylinder of a rotary printing press, comprising an elongated body adapted to be mounted in the printing press so as to extend in parallel with the axial direction of the cylinder and in proximity to the peripheral surface thereof, the body defining a plenum chamber that is open towards the surface of the cylinder and delimited on one side by a wiper adapted to wipe the surface of the cylinder, and on the opposite side by a baffle that forms a gap with the surface of the cylinder, the device further comprising a liquid supply system arranged to supply a liquid into the plenum chamber, a compressed air supply system arranged to supply compressed air into the plenum chamber, and suction device capable of withdrawing both, liquid and air from the plenum chamber.
- More specific features of the invention are indicated in the dependent claims. A preferred embodiment will now be described in conjunction with the drawings, wherein:
- Fig. 1
- is a schematic cross-sectional view of a central impression cylinder and a cleaning device arranged to clean the same;
- Fig. 2
- is an enlarged cross-sectional view of the cleaning device shown in
Fig. 1 ; and - Fig. 3
- is a view showing the cleaning device in a longitudinal section.
- As is shown in
Fig. 1 , a rotary printing press, e.g. a flexographic printing press, comprises a central back pressure cylinder or central impression cylinder (CI) 10 and a number ofcolour decks 12 disposed at the periphery of theCI 10. Only two of thecolour decks 12 have been shown inFig. 1 . Each of these colour decks comprises aprinting cylinder 14 adapted to be adjusted against the peripheral surface of the CI. and ananilox roller 16 adapted to be adjusted against the peripheral surface of theprinting cylinder 14. - When the printing press is operating, the CI rotates in direction of the arrow A in
Fig. 1 , and aweb 18 of a printing medium is passed around the CI, so that successive colour separation images can be printed thereon with theprinting cylinders 14 of the various colour decks. - In
Fig. 1 , the printing press is assumed to be in non-printing state, and theweb 18 has been shown in dashed lines. In this non-printing state, acleaning device 20 for cleaning the peripheral surface of theCI 10 is disposed in a working position directly above the top summit of the CI. Thecleaning device 20 is supported on atransport mechanism 22, e.g. a belt drive, so that it can be moved (horizontally) to a rest position (shown in phantom lines inFig. 1 ) in which it does not interfere with theweb 18. - When it is necessary to clean the peripheral surface of the
CI 10, e.g. because a large amount of dust has been deposited thereon and tends to become detrimental to the print process, theweb 18 is removed, thecleaning device 20 is driven to the working position, and theCI 10 is driven with appropriate speed in the direction of the arrow A, so that the peripheral surface can be cleaned with the cleaning device. - As has been shown in greater detail in
Fig. 2 , thecleaning device 20 comprises abody 24 which extends in axial direction of theCI 10 over practically the entire width thereof and defines aplenum chamber 26 that is open towards theperipheral surface 28 of theCI 10. On one side, the downstream side in direction of rotation of the CI, theplenum chamber 26 is delimited by an elastic doctor blade orwiper 30 that engages thesurface 28 of the CI with its lower edge. On the opposite side, theplenum chamber 26 is delimited by abaffle 32 that forms a narrow gap with thesurface 28 of the CI. Similarly, both axial ends of the plenum chamber are closed off by end walls (no reference signs) which also form a gap with the surface of the CI. - The
body 24 of the cleaning device includes aliquid supply line 34 connected to aliquid supply unit 36. Thesupply line 34 communicates with a number of nozzles 38 (reference signs shown inFig. 3 ) which are distributed over the length of the CI and directed towards the peripheral surface thereof, so that a cleaning liquid, e.g. water or a solvent, can be jetted onto thesurface 28 of the CI inside theplenum chamber 26. - The
body 24 further includes anair supply line 40 connected to acompressed air source 42 and communicating with a number ofair nozzles 44 for jetting compressed air onto thesurface 28 of the CI inside theplenum chamber 26. - The
plenum chamber 26 is further connected to asuction line 46 that is connected to asuction blower 48 via aliquid separator 50, so that both, air and liquid may be sucked-off from theplenum chamber 26 and thesurface 28 of the CI. - The
liquid supply unit 36, thecompressed air source 42 and theblower 48 are controlled by anelectronic control unit 52 which may also control a drive motor for thetransport mechanism 22 shown inFig. 1 . - As can be seen in
Fig. 3 , theliquid nozzles 38 and theair nozzles 44 are arranged alternatingly in longitudinal direction of theplenum chamber 26, and the height of the plenum chamber, as measured in the direction normal to thesurface 28 of the CI, increases gradually from the axial ends towards the central portion where thesuction line 46 is connected to the plenum chamber. - When the
cleaning device 20 has been brought into the working position and a cleaning process is to be started, theblower 48 is activated, so that air is withdrawn from theplenum chamber 26. This air will be replaced by ambient air that will mainly enter through the gap formed between thesurface 28 of the CI and the lower edge of thebaffle 32. As a result, an air current will pass over thesurface 28 below thebaffle 32 with relatively high velocity, so that dust and other contaminants will be removed from thesurface 28 and sucked off. - In a modified embodiment, permitting a more precise control of the air flow through the gap, the continuous gap shown in
Fig. 2 may partly be closed by a comb-like seal that leaves open only a discontinuous gap. - Simultaneously or somewhat later, the
liquid supply unit 36 is activated, and the cleaning liquid is jetted onto thesurface 28 of the CI via thenozzles 38. On the upstream side, as viewed in direction of rotation of the CI, the liquid is prevented from leaking through the gap formed by thebaffle 32, because the counterstream of air entering into the plenum chamber will drive the liquid back into the plenum chamber. Moreover, frictional forces between the liquid and thesurface 28 of the rotating CI will force the liquid towards thewiper 30. Since thiswiper 30 is in elastic contact with thesurface 28 of the CI, the liquid will be wiped off and retained in theplenum chamber 26, from where it is sucked away through thesuction line 46. The liquid will then be collected in theliquid separator 50 from where it may be recirculated. - As is shown in
Fig. 2 , asurge 54 of cleaning liquid will develop inside theplenum chamber 26 in front of thewiper 30, and the amount of liquid in this surge will be determined by an equilibrium between the supply of liquid via thenozzles 38 and the liquid sucked off through thesuction line 46. When thesurface 28 of the CI passes through thesurge 54, any contaminants adhering to that surface will be dissolved in and/or washed away be the cleaning liquid and sucked off through thesuction line 46, so that the entireperipheral surface 28 of the CI will be cleaned very efficiently. - As is shown in
Fig. 3 , the length of a CI is slightly larger than the length of thebody 24 of the cleaning device, andelastic seals 56 are provided for closing the gaps between the CI and the end walls of theplenum chamber 26. It will be understood that the length of the cleaning device is larger than the width of theweb 18, so that the entire part of thesurface 28 of the CI that is involved in the print process will be cleaned. - After at least one or preferably several complete rotations of the
CI 10, theliquid source 36 will be switched off, and thecompressed air source 42 will be activated instead, so that the liquid contained in thesurge 54 will be sucked off and then thesurface 28 of the CI will be blown dry by means of the compressed air jetted out through thenozzles 44. Theblower 48 is kept operating, and its displacement will be larger than the supply of compressed air, so that ambient air is still being sucked-in below thebaffle 32, so that no dirt that might still be present within theplenum chamber 26 will be blown out onto the clean surface of the CI. In this way, the surface of the CI will be thoroughly cleaned and dried, until finally, the cleaning device is moved back into its rest position, so that a new print run can be started. - The height profile of the
plenum chamber 26 that is shown inFig. 3 has the effect that the current of compressed air passing over theCI surface 28 towards thesuction line 46 will have an essentially uniform intensity over the entire length of the cleaning device, so that an essentially uniform cleaning and drying action is achieved. - In a modified mode of operation, the phases in which liquid and compressed air are supplied may overlap, so that the cleaning effect is intensified by the combined action of liquid and compressed air.
