Description
- The present invention relates to a plant for cleaning inking and printing rollers and of the type specified in the introduction of claim 1.
-
DE 9106454U1 describes an apparatus for cleaning items such as inking rollers and other printing unit parts for printing machines by using a water-based cleaning liquid, the apparatus including a cabinet configured as a vessel with a cover and a mesh-formed support face for items to be cleaned, a number of nozzles adapted to spray the items and a pump arranged to supply the nozzles with a cleaning liquid which is recirculated by sucking from the bottom of the cabinet, at which a filter unit with a disposable filter is inserted between a suction branch from the vessel and the nozzles. - There is described an efficient cleaning apparatus which can operate with a relatively small amount of cheap water-based cleaning liquid. This is possible because the cleaning liquid is recirculated, i.e. pumped up from the bottom of the vessel and cleaned efficiently by passing the disposable filter which can be discarded relatively cheaply according to current environmental requirements.
- In addition to this prior art cleaning apparatus which is particularly suited for cleaning small inking rollers and other relatively small printing unit parts, larger special cleaning apparatuses are known which are adapted for cleaning larger inking rollers where the latter are arranged rotating and vertically upright during the cleaning process.
- The development within the printing industry has gone in the direction that the present inking and printing rollers with time have become relatively large and heavy, causing a serious work environmental problem in connection with transport of large and heavy inking and printing rollers between cleaning apparatuses and printing machines.
-
US 2009/139549 A1 discloses a printing cylinder washer having a removable or portable drive assembly, or a series of portable drive assemblies of different lengths to accommodate differently sized print rollers. The drive assemblies have a drive mechanism enabled by a dynamic flow of cleaning solution within the washer reservoir. Furthermore is disclosed the use of an elevation system, an agitation platform, under-immersion spray bars, an ultrasonic-wave cleaning system, and a hatch or door equipped with a thermal breaker in conjunction with the hydro-driven portable drive assembly. - On this background, it is the object of the invention to provide an improved plant for cleaning inking an printing rollers which by simple technical means is capable of counteracting the work environment problems associated with lifting and transporting relatively large and heavy inking and printing rollers between a printing unit the and cleaning apparatus, and not the least handling of such inking and printing rollers in connection with insertion into and extraction out of the cleaning apparatus.
- The plant according to the invention is characterised in comprising a trolley having one or more support bearings for inking and printing rollers being transferred to and from said rotary bearings in the cleaning chamber by lowering and elevating said elevating track system and the trolley, respectively, said trolley being adapted to be led into and out from the elevating track system in said cleaning chamber via fixed track sections of transport racks which are adapted to be placed at respective sides of the cleaning chamber and to be handled by means of separate lifting equipment - such as a forklift truck. By simple technical means it hereby becomes possible to counteract the environment work problems associated with lifting and transporting relatively large and heavy inking and printing rollers between printing unit and cleaning apparatus, and not the least handling such heavy inking and printing rollers in connection with inserting into and extracting out of the cleaning apparatus.
- The general aspect of the invention is to achieve an optimised cleaning process and hereby facilitate handling of relatively heavy inking and printing rollers in such a way that lifting of inking and printing rollers in principle only occurs at the printing unit where inking and printing rollers are transferred to and from the printing unit via the said trolley on the indicated transport racks by means of suitable lifting equipment.
- In other words, this is an appreciable improvement of the working environment in that transfer of the heavy inking and printing rollers between transport rack and cleaning apparatus can be effected entirely without any lifting operations as during the entire transportation between cleaning plant and printing unit, the inking and printing rollers are supported on the indicated trolley on transport racks.
- Alternatively, the inventive plant can be designed such that it includes an apparatus with several successively arranged cleaning chambers, such as a primary cleaning chamber in which is performed a pre-cleaning of inking and printing rollers by applying a special cleaning liquid via a system of nozzles, and a secondary cleaning chamber in which is performed a finishing treatment in the form of high-pressure flushing and drying by means of compressed air.
- The plant according to the invention can be suitably designed such that the transport racks with the fixed track sections are adapted in height and in width to the elevating track system in the cleaning chamber of the apparatus such that the fixed track sections of the transport racks can be disposed opposite the elevating track system at respective sides of the plant.
- With the intention of further automating the cleaning process, the plant according to the invention may advantageously be designed such that in connection with at least one primary cleaning chamber there are provided means adapted to get hold of a foremost trolley on a foremost transport rack located in front of the primary cleaning chamber and actively draw the foremost trolley with one or more inking or printing rollers into the cleaning chamber.
- The plant according to the invention may suitably be designed such that the inserting means are constituted by a hydraulically, pneumatically or electrically powered mechanism with a piston with a palm mechanism adapted to interact with a projecting part of the trolley such that a foremost trolley can be drawn into the cleaning chamber.
- The plant according to the invention may be designed in size such that the apparatus including cleaning chamber with associated rotary bearings, the trolley and the transport racks is provided in sizes adapted to inking and printing rollers with lengths between 300 and 3000 cm.
- The invention is explained more closely in the following with reference to the drawing, on which:
- Fig. 1
- shows a perspective view of an embodiment of a plant according to the invention where a trolley with two inking or printing rollers is ready to be moved into a cleaning chamber of a cleaning apparatus;

- shows a perspective view of a part of a plant according to the invention where a transport rack with two inking or printing rollers are shown enlarged;
- Fig. 5
- shows a perspective view of a plant according to the invention where the transport system of the plant itself is shown without a cleaning chamber, for illustrating the elevating track system in the cleaning chamber;
- Fig. 6
- shows a perspective view of a second embodiment of a plant according to the invention where two cleaning chambers are arranged in succession; and
- Fig. 7
- shows a perspective view of a modified embodiment of a plant according to the invention where a transport rack is designed with drain tray and collecting container etc.
- The
cleaning plant 2 shown inFig. 1 includes a cleaning apparatus 6 for cleaning inking andprinting rollers 4 that during transport to and from the cleaning apparatus 6 are disposed on atrolley 14 insupport bearings 16, thetrolley 14 disposed onfixed track sections 18 of atransport rack 20 during the transportation. - In
Fig. 2 , adoor 28 for acleaning chamber 8 of the cleaning apparatus 6 has been opened by activating an opening/closingcylinder 30, and thetrolley 14 with two inking andprinting rollers 4 are on their way into thecleaning chamber 8. - In
Fig. 3 appears that at the same time, asecond trolley 14 is on its way out from the opposite side of thecleaning chamber 8 where thetrolley 14 with inking andprinting rollers 4 are disposed onfixed track sections 18 of atransport rack 20 at the opposite side of the cleaning apparatus 6. - In
Fig. 4 appears atrolley 14 with two inking andprinting rollers 4 in ready position onfixed track sections 18 of atransport rack 2; through a window in thedoor 28 an inking orprinting roller 4 under cleaning treatment appears incleaning chamber 28. -
Fig. 5 serves to illustrate the moving system of thecleaning plant 2 according to the invention where thecleaning chamber 8 itself has been removed. At opposite sides of the apparatus 6 there are providedtransport racks 20 withfixed track sections 18. Atrolley 14 is placed on theelevating track system 12 which is supported by four lifting/lowering cylinders 26 (only two are shown) such that thetrack system 12 andtrolley 14 can be moved downward so that inking andprinting rollers 4 possibly placed introlley 14 are transferred torotary bearings 10 in thecleaning chamber 8 so that the inking andprinting rollers 4 can be rotated during the cleaning process, as indicated. -
Fig. 6 shows analternative cleaning plant 3 which includes an apparatus 5 with several successively arranged cleaning chambers, e.g. a primary cleaning chamber 7 in which is performed a pre-cleaning of inking andprinting rollers 4 by applying a special cleaning liquid via a system of nozzles, and a secondary cleaning chamber 9 in which e.g. is performed a finishing treatment in the form of high-pressure flushing and drying by means of compressed air. -
Fig. 7 shows a modified embodiment of acleaning plant 2 according to the invention where a larger inking orprinting roller 4 is placed on atrolley 14 ontransport rack 20 which includes adrain tray 23; furthermore, acollecting container 22 and afilter 24 are seen. - The
plant 2 including the apparatus 6 withcleaning chamber 8 and associatedrotary bearings 10, thetrolley 14 and thetransport frames 20 may be provided in sizes adapted to inking and printing rollers with lengths between 300 and 3000 cm.
With the intention of further automating and optimising the cleaning process, the plant according to the invention may advantageously be designed such that in connection with at least one primary cleaning chamber there are provided inserting means adapted to engage a foremost trolley on a foremost transport frame located in front of the primary cleaning chamber, and actively pull the front trolley with one or more inking or printing rollers into the cleaning chamber. - The inserting means can e.g. be constituted by a hydraulically, pneumatically or electrically powered mechanism with a piston with a palm mechanism adapted to interact with a projecting part of the
trolley 14 such that aforemost trolley 14 can be drawn into thecleaning chamber 8. When the saidforemost trolley 14 is drawn into thecleaning chamber 8, atrolley 14 possibly already drawn therein will automatically be pushed out of thecleaning chamber 8 or further into a possible secondary cleaning chamber 9 if the apparatus 6 includes more than onecleaning chamber 8. - The
plant 2 may furthermore include an dedicated accumulation track in front of thecleaning chamber 8 of the apparatus 6 where a number oftransport racks 20 can be arrayed with mutuallyflush track sections 18 such that atrolley 14 situated on atransport rack 20 may easily be transferred to atransport rack 20 disposed in front thereof, etc. Within the main aspect of the invention, such an accumulative track withtransport racks 20 can include feeding means that are adapted for providing automatically a continuous transfer oftrolleys 14 to anempty transport rack 20 disposed at the front in the accumulation track. - Finally, it is to be emphasised again that the general aspect of the invention is to facilitate handling of relatively heavy inking and
printing rollers 4 in such a way that lifting of inking andprinting rollers 4 in principle only occurs at the printing unit where inking andprinting rollers 4 are transferred to and from the printing unit via thesaid trolley 14 on the indicated transport racks 20 by means of suitable lifting equipment. In other words, transfer of the heavy inking andprinting rollers 4 betweentransport rack 20 and cleaning apparatus 6 can be effected entirely without any lifting operations as the inking andprinting rollers 4 during the entire transportation betweencleaning plant 2 and printing unit is supported are supported on the indicatedtrolley 14 ontransport racks 20 which are handled by means of separate lifting equipment, e.g. a forklift truck. -
