Definitions
- the present invention relates to a cooling and humidifying unit for Rotary printing machines, in particular for rotary printing machines for processing of material webs.
- An apparatus for dissipating heat from a web includes one Cooling roll with a cylindrical surface.
- the web is moving along one Path that extends partially around the chill roll. Between the two side parts the web extends around part of the cylindrical outer surface of the cooling roll in Circumferential direction a nozzle.
- An air flow is counteracted through the middle part of the nozzle directed a middle part of the web and above a point where the web normally comes into contact with the chill roller around the middle part of the web bend and bring it into contact with the chill roll in this way.
- Lateral nozzle parts extend on both sides of the middle part of the nozzle, namely below the point where the middle part of the web is towards the chill roll is bent. This creates a smoothing in the transverse direction and along the middle Part of the track achieved.
- the present invention relates to the cooling of a printed or coated material web, which in particular according to the offset printing process was printed and consists of paper.
- the material web has after applying Color passes through a heating zone and is passed over a variety of cooling rolls Cooling roll stand led.
- the flow of the cooling medium through the cooling rollers a cooling roll stand by two different cooling circuits different Temperature levels generated and against the direction of travel of a material web over the Cooling rollers directed.
- the cooling rolls are more conventional Wise arranged quite a lot of construction and floor space and only two of the Cooling rollers are arranged one above the other.
- EP 0 627 311 B1 relates to a web cooling device.
- the device according to This publication allows cooling one in a dryer Web printing machine heated printing material web with a downstream of the dryer and the support roller or turning device guiding the printing material web.
- a second downstream of the support roller or turning device and the printing material web leading roller with a first liquid application roller for applying liquid on a first side of the printing material web and a second liquid application roller to apply liquid to a second side of the substrate.
- the Liquid application rollers are on opposite sides of the Printing material web between the support roller or the turning device and the second Roller arranged.
- the liquid application rollers are together one between the support roller or turning device and the second roller assigned to the printing substrate web section and offset from one another. They create a pressure contact along a contact area on the printing material web in the Way that the substrates can be wetted.
- the invention has for its object to significantly shorten the length of a cooling and conditioning unit and at the same time reduce the Increase cooling effectiveness.
- Another object of the present invention is that in one Print shop necessary footprint for such Correct the cooling and conditioning unit considerably. After all, with the solution according to the invention a lateral run of the material web during the passage the cooling and conditioning unit can be prevented.
- the cooling rollers may be arranged offset from one another around the material web passing through them to impress an essentially arched path and high Realize wrap angle.
- the cooling rolls according to the present invention can be arranged offset from each other, both offset in height as also offset with respect to the length of the housing. Due to the staggered arrangement and applying a substantially arcuate web path high wrap angles can be achieved on the chill rolls, resulting in a particularly effective heat transfer.
- the cooling and conditioning unit according to the invention present invention comprise a conditioning unit for applying a liquid for example moisture or silicone on one or both sides of the Conditioning unit passing material web.
- the conditioning rollers of the Conditioning plant can be arranged opposite each other and either a common liquid container or a shared liquid container have to maintain a constant fluid supply to the aforementioned surfaces enable.
- Cooling rolls have a relatively small diameter in relation to their width, i. e. between 100 mm and 250 mm, preferably about 250 mm in diameter.
- the relatively small one Diameter of the cooling rolls according to the invention allows a high one to be maintained Traction levels between the web and the surfaces of the chill rolls, with little Air is trapped between the roll surface and the web. This in turn favors the heat transfer coefficient and enables the elimination of the Corrugation of the web across the web width during the passage of the cooling rolls in Web direction.
- the arrangement of the cooling rolls according to the invention one above the other within the housing uses its height very effectively, compared to that of the prior art known housings. Exploiting the height of such instead of its length allows a short overall length and therefore little floor space in the printing shop.
- the cooling and conditioning unit according to the invention is relatively close to the following one Turning bar superstructure is only a small free path for the Post-evaporation of solvents is possible, which means additional post-evaporation restricted, so that the operating personnel no additional solvent pollution of the Breathing air is exposed.
- the cooling and conditioning unit according to the invention can be one Dryer of a rotary printing machine for both commercial and colored printing Newspaper printing must be assigned.
- the cooling and conditioning unit 1 is immediate arranged behind the outlet of a dryer.
- the dryer contains a corresponding one upper dryer zone and a corresponding lower dryer zone, between which there is extends a web running level.
- the cooling and conditioning unit 1 comprises a first one Cooling roller 8 with a diameter 24.
- the web 7 of either one or both sides are printed, is deflected by the first cooling roller 8 by 90 ° and follows a downwardly extending web path, which the web 7 in Web running direction 9 leads.
- a conditioning unit which is used for the application moisture or other fluid such as silicone on one or both Surfaces of the material web 7 allowed.
- the conditioning unit 11 closes two Conditioning rollers 12, which are arranged opposite one another.
- Each of the Conditioning rollers 12 are immersed in and conveyed from a liquid container apply a thin film of liquid to the material web.
- the material web 7 becomes a downward trajectory embossed, within the downward trajectory it is provided with said liquid film, with no web deflection between the first cooling roller 8 and a cooling roller 14 arranged further downstream is coming. It is only through the cooling roller 14 that the further web path 12 becomes one again diverted upward extending path portion, d. H. the material web 7 experiences one Redirection by about 180 °.
- the material web On a further cooling roller 15, the material web is rotated through an angle of approximately 180 ° distracted. On a further cooling roller 16, the material web 7 is turned through an angle deflected more than 180 °, but less than 270 °, the material web 7 of this pair of Cooling rollers leave in an inclined direction, with the web path slightly upward is pointing.
- a further pair of cooling rolls consisting of the cooling rolls 17, 18, which are arranged in approximately the same configuration as the two previous ones described cooling rollers 15, 16.
- the material web 7 runs on the first cooling roller 17 of the said further pair of cooling rollers starting from their inclined path on, the material web 7 the surface of this cooling roller 17 further Cooling roller pairs wrapped at an angle between 180 ° and 270 °. After that the material web 7 the surface of the first cooling roll 17 further Cooling roller pair 17, 18 has passed, it runs in an inclined A web path section that is between the second cooling roller 18 of said Cooling roller pair and a cooling roller 19 extends.
- the material web 7 is during the Passage of the cooling rollers 20, 21 deflected in the manner shown. After the Material web 7 has left the surface of the second cooling roller 21, the runs Material web 7 in the cooling and conditioning unit 1 in the horizontal direction.
- the cooling rollers 8, 14, 15, 16, 17, 18, 19, 20 and 21 all in a staggered configuration with respect to one another arranged, the first cooling roller 8 closer to the inlet of the material web in the housing 2 7 is arranged in the cooling and conditioning unit 1 compared to the cooling rollers 15 and 16.
- the height 3 of the housing 2 can accommodate the plurality of Cooling rollers 8, 14, 15, 16, 17, 18, 19, 20 and 21 can be used. Because the web of material the cooling and conditioning unit 1 according to the present invention in close proximity leaves for a subordinate turning bar superstructure, it is only for a very short one Exposed to the environment, resulting in only a minimal boundary layer build-up on both Sides of the freely moving web of material is possible.
- the material web essentially leaves the cooling and conditioning unit 1 horizontal direction to enter a turning bar superstructure, the one Longitudinal folding section of a folder or a longitudinal cutting section of a Turning bar superstructure is upstream to a variety of train strands from the To produce material web 7.
- a high degree of web tension exerted on the material web enables a relatively close contact between the material web surface 7 and the surface of a corresponding cooling roller which is just passing the material web 7. This improves the conditions for optimal heat transfer. Additional web tension rollers or air nozzles can be avoided by high web tensions obtained in this way within the material web 7. Since the cooling rollers according to the present invention are optimized with regard to a certain inertia, they can only be driven within the cooling and conditioning unit 1 due to friction, so that an additional drive can be deployed. However, it is optionally possible to drive one or a plurality of the cooling rolls according to the invention within the cooling and conditioning unit 1 with a separate drive motor.
- Another advantage of the invention is thanks to the immediate transition from Material web 7 from the dryer outlet into the cooling and conditioning unit inlet 6
- This allows boundary layers to build up on the surfaces of the material web 7 be eliminated.
- the boundary layers adhering to the surfaces of the material web 7 have the disadvantageous effect that they have an air cushion between the surface of the first Form cooling roller 8, which is located closest to dryer outlet 6.
- the Air cushions in turn result in disadvantageous oil condensation on their surface, which represents a detachment of the ink on the first cooling roller and one Retransfer of ink deposited on the surface of the first cooling roller already printed side of the material web results.
- the small diameter 24 of the Chill rolls also allow a relatively high web tension to be maintained for close contact between the web and the heat-exchanging surfaces.
- the material web 7 passes through the cooling and Conditioning unit 1, the material web 7 having a plurality of cooling rolls only small diameter 24 happens.
- the diameter of the cooling rolls is relatively small in terms of their width. Since the plurality of cooling rolls 8, 14, 15, 16, 17, 18, 19, 20 and 21 are arranged in a staggered configuration with respect to one another within the housing 2 a plurality of cooling rollers can also be used in the housing 2 whose overall height 3 can be accommodated.
