- US 5 568 768 A, US 5 255 606 A, DE 25 22 743 A1, DE 23 17174 B2, US 2 171 631 A and DE-AS 1 561 029 disclose devices for cleaning rollers with an in Longitudinal direction of the roller rotating cleaning element.
- the invention has for its object to provide a device for cleaning a roller or a cylinder.
- the advantages that can be achieved with the invention are, in particular, that a high and reliable cleaning effect can be achieved with a comparatively simple structure of the device, it being possible to use an in particular liquid cleaning agent.
- the cleaning agent can also be reprocessed and circulated, at the same time allowing the device to self-clean.
- the device according to the invention can remain in a fixed position relative to the roller to be cleaned, which means that expensive set-up times can be avoided.
- Another advantage is that the cleaning effect of the device according to the invention can be easily adapted to the degree of contamination of the roller to be cleaned.
- Fig. 1 is a schematic representation of a top view of a device according to the invention
- FIG. 2 is a schematic representation of a section along the section line I - 1 in FIG. 1
- the device 01 according to the invention is arranged in the immediate vicinity of a roller 02 or cylinder to be cleaned, for example a forme cylinder or a guide roller of a printing machine, not shown.
- the device 01 first of all has a first carrier element 03 in the form of a toothed belt, which is guided over two axially spaced rotatable guide elements in the form of pulleys 04 and 05, respectively.
- a loop-like, endlessly circulating carrier element is formed with a first strand 06 facing the roller 02 and a second strand 07 pointing away from the roller.
- a drive not shown, which applies torque to at least one of the pulleys 04 or 05 and thus drives the toothed belt 03 in the direction F of a longitudinal axis of the roller 02.
- the two Pulleys 04 and 05 more precisely their central axes 08 and 09 running perpendicular to the plane of the drawing, have an axial spacing which, in the exemplary embodiment shown here, corresponds essentially to the axial length of the roller 02 to be cleaned.
- the toothed belt 03 is provided with cleaning elements 10 in the form of bristle-like bristle elements, which are arranged on the toothed belt 03 in such a way that they extend radially outwards, based on the loop formed by the toothed belt 03, point.
- the toothed belt 03 is not provided with bristle elements 10 over its entire length; rather, the timing belt is bristled only 03 over half its length. As a result, the toothed belt 03 can be brought into the position shown in FIG.
- the device 01 is provided with a series of cleaning chambers 11, 12, 13, 14 and 15 arranged one behind the other, through which the toothed belt 03 and thus the bristle elements 10 pass in succession.
- the bristle elements 10 are at least partially freed from impurities picked up from the surface of the roller 02. This can, for example, be achieved or at least supported by wipers, not shown, which are arranged in the respective cleaning chambers.
- each cleaning chamber 11, 12, 13, 14 and 15 has an inlet 16 for a cleaning agent for cleaning the bristle elements 10.
- a cleaning liquid for example, can be used as the cleaning agent Water, optionally also with the addition of solvents, soaps, alkalis or the like, can be used.
- the cleaning agent is flushed into the cleaning chambers 11, 12, 13, 14 and 15 through this inlet 16, the bristle elements 10 guided through the cleaning chambers being wetted and freed of their dirt load.
- each cleaning chamber 11, 12, 13, 14 and 15 has an outlet 17 for the cleaning agent which is contaminated after cleaning the bristle elements 10.
- a further chamber 18 is arranged, which is also passed through by the toothed belt 03 and the bristle elements 10.
- this chamber 18 into which no cleaning agent is supplied, the dehumidifying of the bristle elements 10 takes place to a certain degree depending on the respective application.
- This dehumidification can take place, for example, by means of a stripping element, not shown, which comes into engagement with the bristle elements 10, or by blowing in compressed air or the like.
- the stripped or blown-off cleaning agent is discharged from the chamber 18 through an outlet 19.
- the outlets 17 of the cleaning chambers 11, 12, 13, 14 and 15 and the outlet 19 of the chamber 18 open into a common collecting duct 20.
- the collecting duct 20 is connected to a collecting vessel 22 via a line 21, in which the dirty detergent is directed.
- the soiled cleaning agent is passed through a filter element 23 in or following the collecting vessel 22 and is cleaned of the impurities there.
- the cleaning agent which has been reprocessed in this way and optionally replenished is then stored in a second collecting vessel 24 and from there again by means of a pump 25 and a line 26 via the inlets 16 Cleaning chambers 11, 12, 13, 14 and 15 given. Overall, therefore, an essentially closed detergent circuit can be implemented.
- two toothed belts 03 and 27 are connected one behind the other in relation to the circumferential direction of the roller 02, i. H. arranged one above the other.
- the second toothed belt 27 is provided with bristle elements 28 in the same way as the first toothed belt 03 over half its length.
- the toothed belt 27 is guided in the same way as the toothed belt 03 over pulleys, not shown, whose central axes are aligned with the central axes 08 and 09 of the pulleys 04 and 05.
- At least one of the belt pulleys of the toothed belt 27 has a drive with which this belt pulley can be acted upon with a torque for driving the toothed belt 27.
- the drive of the toothed belt 03 and the drive of the toothed belt 27 are basically independent. In the embodiment shown here, the drive of the toothed belt 03 and the drive of the toothed belt 27 are in opposite directions, so that the direction of rotation of the belt pulleys and thus the toothed belt 03 and 27 itself are in opposite directions. The directions of rotation of the drives can be reversible.
- a guide element 29 is provided between the pulleys 04 and 05 of the toothed belt 03 and the not shown pulleys of the toothed belt 27, which extends in the embodiment shown here essentially over the entire space between the respective pulleys.
- the guide element 29 has groove-like depressions 30, 31 and 32, 33, one above the other, in which the respective strands of the toothed belts 03 and 27 are guided. In this case, there is both a guidance perpendicular to the main planes formed by the toothed belt loops and a support of the toothed belts 03 and 27 against the groove base.
- a component 34 is arranged on the guide element 29, in which the cleaning chambers 11, 12, 13, 14 and 15 and the chamber 18 for the upper toothed belt 03 and, in principle, the same Way, the cleaning chambers 35 and the chamber for the lower toothed belt 27 are formed. All chambers open with their outlet 17 or 19 (upper toothed belt 03) and 36 (lower toothed belt 27) into the common collecting duct 20, which is also formed directly in component 34.
- the inlets 16 (upper toothed belt 03) and 37 (lower toothed belt 27) for the inflow of cleaning agent, the cleaning chamber 11, 12, 13, 14 and 15 and 35 are also arranged.
- Inlets 16 and 37 open into manifolds 38 and 39 which are attached laterally at the top and bottom of component 34 and are supplied with cleaning agent by pump 25 via line 26.
- the roller 02 to be cleaned has on its surface a plate 40 for flexographic printing, which is to be freed of impurities, in particular ink residues, after a printing process which has ended as intended.
- the cleaning chambers 11, 12, 13, 14 and 15 are first rinsed with cleaning liquid and the bristle elements 10 are thereby wetted.
- the bristle elements 10 migrate through the chambers arranged one behind the other and after rinsing with detergent in the cleaning chambers 11, 12, 13, 14 and 15, the bristle elements 10 in the second chamber 19 are dehumidified to the extent that on the one hand If an undesired leakage of cleaning agent from the gap between the roller 02 and the device 01 is largely swept over the roller surface, on the other hand, when the plate 40 arranged on the roller surface with the bristle elements 10 is brushed over, a sufficient amount of cleaning agent is transferred to the plate, to soften the color to be removed by the cleaning process.
- the bristle elements 10 initially transmit both cleaning agent to the surface to be cleaned and mechanically abrasive removal of the dirt. With increasing release of the residual moisture of the bristle elements 10 onto the surface of the roller 02 or the flexographic plate 40, the bristle elements 10 are able to take up the color residues from the roller surface and via the rinsing in the cleaning chambers 11, 12, 13, 14 and 15 hand in for separation.
- the cycle time ie in particular the dwell time and amount of the cleaning agent on the roller surface, is particularly due to the adaptation of the speed of the roller 02 and the speed of rotation of the toothed belt, but also freely adjustable within wide limits by adjusting the residual moisture content of the bristle elements 10 in the chamber 18 depending on, for example, the degree of contamination.
- the cleaning area in particular can be enlarged and the cleaning time can thereby be shortened. Due to the opposing movement of the two toothed belts 03 and 27, the flanks opposite the intended elevations and / or depressions of the roller surface in the direction of movement of the toothed belts 03 and 27 are also subject to a more uniform cleaning effect, since "shadow areas" are largely prevented.
- the device 01 is also provided with a housing 41 which is open towards the roller 02.
- the edge areas of the housing 41 in the area of both end faces of the roller 02 have splash plates 42 and 43 which, depending on the direction of rotation of the toothed belts 03 and 27, cause an uncontrolled spraying of cleaning agent when the bristle elements 10 emerge from the chamber 18 or contaminated Prevent cleaning agents when the bristle elements 10 enter the housing 41.
