Definitions
- the invention relates to a dryer with integrated cooling unit as he is subordinated particularly web-processing rotary printing machines, as well as on a Procedures for drying a material web.
- US 5,471,847 discloses a web cooling device with the features according to the preamble of patent claim 1.
- the disadvantages of previous drying concepts should be overcome by that the web primarily by evaporation of a liquid instead of through Heat conduction or convection is cooled. This leaves enough moisture in the Web, so that a shrinkage of the web is omitted and the static charge of the web takes a minimum.
- the web is up Dried to 2% residual moisture content and thereby absorbed from the surrounding air Moisture up to a moisture content between 4% and 6%. This additional Moisture absorption on the environment according to US 5,471,847 by a specially to intended moisture applicator realized.
- EP 0 723 126 A1 discloses a control device and an arrangement for one in one industrial dryer continuous drying process.
- a dryer for floating a web for gradual drying of the web recirculates solvent-containing air inside the dryer. It will be a procedure for better control of the solvent-containing air inside the dryer proposed. This will cause the condensing of the solvents and various solvents based by-products significantly reduced or even completely eliminated.
- Solvent raising overall safety levels, in which areas are avoided altogether, in which solvent-containing air in high Concentrations.
- Ambient air enters the dryer and is with the mixed solvent-containing air in the dryer interior.
- the air mixture becomes the first Zone of the dryer according to EP 0 723 126 A 1 supplied again.
- the open flame of the Burner is thereby cooled by ambient air from the outside. After cooling the open flame through ambient air will recirculate air from inside the dryer the fresh air mixed.
- ambient air is used to to cool the open burner flame and undesirable compounds more organic eliminate volatile components.
- the residence time of the combustion mixture in the burner unit does not appear sufficient in the solution according to EP 0 723 126 A1 sized.
- DE 32 07 461 A1 relates to a method and an apparatus for drying and subsequent cooling of printed in particular by the offset printing process Webs.
- the invention relates to a method according to the Offset printing process. After the contactless drying of the printed web The web is guided in S- or Z-train over several cooling rollers. It is through Moistening of the jacket of the first cooling roller under the web side, the first is cooled, an easily cleavable water film between the web and roll shell brought. This measure causes the physical contact of the web with this and the other cooling rollers not soft thermoplastic ink is split. The inclination of the web to form waves across the Passage direction is reduced because the cleavage of the water film as a result of their different thickness in the printed and the non-printed and therefore strong dried areas leads to a uniform moisture distribution.
- the chill roll stand is separate from the upstream dryer the rotary printing machine arranged.
- the known dryer / chill roll stand configurations show separate ones Dryer housings and separate housings for chill rolls and rewet units, which are further down from the web level. These are separated arranged housing have the significant disadvantage that occurring in a housing Problems in the next, this rearranged housing, pose further problems for example, the lateral course of the web.
- Known chill roll stands require a relatively large footprint and thereby increase the overall length a web-fed rotary printing machine.
- Another object of the present invention is to be seen in the overall length reduce a rotary printing press. Another object of the invention is to be seen in it, to avoid the operator of a roller rotation of the Post evaporation.
- the dryer may be a heating zone, a Evaporating zone and a cooling zone include, which may be separated from each other or wherein the heating zone and the evaporation zone are combined with each other and only separated from the cooling section.
- each of these zones are corresponding upper and lower blowers arranged which conditioned air, for example Burner units supplied heating air and emerging from the nozzle bar circulating air, again to the nozzle bars, which extend through the zones of the dryer, lead back.
- process air and hot air ducting methods which are suitable, a dryer according to the present invention, either in countercurrent or operate in Gleichstrom Kunststoffest.
- a method for treating a material web run the interconnected methods of heating, the Evaporating, cooling and cooling to a chill roll stand all in one common housing, which from the surrounding ambient atmosphere is encapsulated.
- a in the inventive arrangement of a combined Trockners /dewalzenstandgephinuses entering web has at its entry in essentially the same entry parameters compared to their exit parameters such as For example, the lateral position of the web, the temperature level and the moisture content.
- FIG. 1 shows a dryer / chill roll stand configuration according to the present invention Invention, wherein on the outside of the dryer, a burner unit is housed.
- a dryer 1 comprises a first section 1.1, as well as a second section 1.2 and a third section 1.3.

- An upper third blower 16.3, the fresh air 18 with Ambient air parameters is supplied and a part of the return air 21, as Cooling zone to be regarded third dryer section 1.3 is supplied.
- blower 16.4 is return air 21 from the upper Nozzle bar row 14.2 of the second dryer section 1.2 of the exhaust pipe 6 fed to the optionally an afterburner can be arranged downstream.
- Return air 21 of the nozzle bar row 14.3 of the cooling zone of the dryer, i. e. Section 1.3 is used by the connecting tubes 28, 29 passed to the first dryer section 1.1.
- a cooling and conditioning unit 2 is integrated into the housing of the dryer 9.
- the material leaving the third zone 1.3 of the dryer material web enters directly from the dryer in the cooling and conditioning unit 2, without the ambient air outside the dryer housing 9 have been exposed.
- the last of the cooling rolls 27 may have a separate drive unit 23 in order to ensure a correct inlet of the web leaving the cooling and conditioning unit 2 into the downstream turning bar superstructure.
- FIG. 2 shows an air routing scheme within a dryer according to the present invention.
- FIG Invention wherein process air is passed around a section of the dryer.
- Hot gas 20 can also be supplied to the first dryer section 1.1 can be seen, as can be seen in the air guide scheme of FIG.
- the hot gas 20 and the air gas mixture which via the connecting tube system 28, 29 in the first Dryer section is led to nozzle rows, which are on both sides of the Bahntransportebene are arranged and a floating transport this Allow material webs.
- Return air 21 of the nozzle rows in the first Drier section 1.1 is an evaporation section 1.2 through an opening in the Separator 30 is supplied, which between the first and the second Drum section 1.1 or 1.2 may be provided.
- the Separator 30 are also omitted to allow unimpeded overflow of the Return air 21 of the nozzle rows of the first dryer section 1.1 in the To ensure evaporation section 1.2 of the dryer 1.
