Description
By first invention thought, the present invention relates to a kind of method of regulating the dry-web of new printing, paper web cools off after drying, and when cooling off the last time the latest, before preferably cooling off the last time, infeeded the conditioning agent of humidification again on the two sides, and, the present invention relates to a kind of equipment of implementing the method by another invention thought, comprise be located at paper web transporting flat above and below, be arranged in the cooler adjacent region with the drier downstream, preferably at the sprayer of cooler upstream, they can be for a kind of the conditioning agent of humidification again.
As everyone knows, the moisture that when infeeding in drying again, loses by means of so-called damping device again at the paper web behind the drier inner drying.For this reason, by before the chill roll frame or by the chill roll frame time, on the paper web of drying, add water.Also known, in order to seal the surface of printing, the paper web silicone-treated of printing.Adopt so-called silicone device so far, it is located at the downstream of chill roll frame for this reason.Therefore, so far for to paper web for humidification liquid and silicone again, the operation that needs twice to separate, and thereby also need two independent devices that infeed, they are by the chill roll frame distance that separates each other.Do pretty troublesome like this and thereby be undesirable.
Therefore,, the objective of the invention is to take simple and economical measure to improve the described method and apparatus of preface, overcome these shortcomings of mentioning as starting point.
Be that to reach the measure that this purpose takes be can supply with the conditioning agent of the face of a printing of paper web at least and be made up of the mixture of a kind of liquid of humidification again and silicone aspect the method for this type.
The measure of taking for the purpose that reaches the equipment aspect is, being at least sprayer that each printing surface of paper web sets respectively in the equipment by this type can be for the mixture of being made up of humidification liquid and silicone again.
By measure of the present invention, guarantee to be coated with silicone and carry out jointly with humidification again.Therefore do not need the silicone device of oneself, what link therewith is to have exempted complicated structure and the needs on the space.Do the accessibility of paper web in the zone that also helps between the folding machine in chill roll frame and downstream like this, the silicone device is installed there so far.Another outstanding advantage by measure of the present invention is, silicone is invaded in the paper web with humidification liquid again and porous paper web in fact dearly.Therefore, opposite with so far silicone-treated, do not only like this and add silicone on the surface, and in the darker cross-sectional area in in-position.The favourable result who brings thus is, not only reduced surface roughness, and makes paper web very soft on the whole and can be out of shape well.Therefore when vertical and horizontal are folding, can obtain fold line more clearly in an advantageous manner.So can cancel the processing of past fully with folding assisted liquid.With add again that wet process combines and therefore than so far greatly in advance in the silicone-treated of upstream enforcement, advantageously also cause the chill roll of chill roll frame to obtain a thin layer of silicone, it prevents that pigment is deposited on the chill roll, improves heat conduction and thereby improves cooling effect.In addition, reduced its electrostatic charge by silicone-treated, thereby can be more convenient for for example in folding machine, being for further processing by the deep infiltration of paper web of the present invention.
The favourable design of main measure and appropriate further developing are described in the dependent claims.
For example appropriate is a kind of mixture of being made up of rewetting liquid and silicone of each face confession of paper web.Guarantee with the one or both sides printing irrelevantly thus, paper web is made soft in the mode of the best.In addition, also cancelled any adjustment work when the paper web of one side printing changes over the paper web of two-face printing thus.
Another appropriate measure is that the mixture that constitutes conditioning agent contains the silicone of 0.1%-2%, and all the other are water.Can limit the consumption of silicone thus.However still can obtain the outstanding result of above-mentioned each side.
By further developing of main measure, can be sprayer and set a flow regulator, it can be by one at suction side and a pump feed that is provided with the container cooperating of liquid-level switch, wherein container is connected with feed pipe, comprise a stop valve and the flow measurement device that to handle by liquid-level switch in the feed pipe, and container can add silicone by means of a mixing arrangement, mixing arrangement has measuring pump, the suction side of measuring pump and the silicone container cooperating that can handle according to the output signal of flow measurement device.These measures can realize the accurate proportioning of silicone component by some simple devices.
Other favourable designs of main measure and appropriate further developing in remaining dependent claims illustrate, and can be by following by means of further finding out in the explanation of accompanying drawing to embodiment.
The accompanying drawing that the following describes is represented by a signal vertical section by equipment of the present invention.
Application of the present invention is cylinder press generally, is drier in its downstream and follows by the chill roll frame.This class configuration is known and thereby need not to describe in detail.
Expression in the accompanying drawings should be in the cylinder press that not have expression the paper web 1 of two-face printing, after last printing mechanism's discharge of Biao Shi cylinder press never, by drier 2 and the chill roll frame 3 that is attached thereto.Drier 2 has three along the tandem district of paper web 1 traffic direction, that is the thermal treatment zone 4, heat preservation zone 5 and cooling area 6.For each district sets drier 2 cabinets.Adding dividing plate between in succession the cabinet each other, they have the perforation seam of paper web 1 usefulness respectively.
In the thermal treatment zone 4 and heat preservation zone 5 to paper web 1 heat supply air, shown in nozzle 7.The cabinet of cooling area 6 of attaching troops to a unit comprises an integral body with 8 adjusting devices that indicate, and it is used for to new printing and dry paper web 1 for humidification liquid again with supply silicone simultaneously, and paper web is in the thermal treatment zone 4 and lost many moisture during heat preservation zone 5 inner dryings.For humidification again adopts water, the moisture that during drying loses with the alternative paper web 1 of these water.By with new printing of silicone-treated and dry paper web 1 sealing surfaces, reduce surface roughness, improve pliability and foldability.
For the paper web that just is printed on one side, silicone-treated can be limited to the side of this paper web printing.But expectation is that silicone not only remains on the surface, and can permeate darker level with humidification liquid again, makes the paper particularly soft thus.Owing to this reason, appropriate is that the side of not printing on the paper web that only is printed on one side not only supplies humidification liquid again, and supplies silicone.In illustrated giving an example, paper web 1 is answered two-face printing, so silicone-treated is all made on the regulation two sides anyway.
Silicone is added in the water that is used as again humidification liquid.Here the silicone degree of depth is in the 01.%-2% scope, according to selections such as the kind of paper, web speed.All the other are water.Therefore, handle by the conditioning agent that said mixture constitutes, finished the humidification again and the silicone-treated of paper web 1 simultaneously by paper web 1 usefulness.
The conditioning agent that is added on the paper web 1 partly evaporates.Heat of evaporation absorbs from paper web 1, so paper web cools off by the mode of expectation.Certainly, when the amount of determining to infeed, should be taken into account this part of conditioning agent evaporation.
The conditioning agent that is made of said mixture contactless type rightly is injected on the paper web 1.This still finishes in drier 2 inside are comprising the cooling area 6 of drier 2 outlets in for example illustrated.But also it is contemplated that adjusting device 8 is located at outside the drier 2, for example in the zone between drier 2 and chill roll frame 3 or in chill roll frame 3.Because especially implemented humidification again, so need not establish adjusting device in chill roll frame downstream by adjusting device 8.
Above mentioned adjusting device 8 comprises that being arranged in paper web 1 transporting flat above and below arranges 9 along the continuous nozzle of whole width.In illustrated giving an example, establish nozzle row respectively.Can certainly adopt the sprayer unit that constitutes by a plurality of nozzle rows.Blow out the conditioning agent that infeeds nozzle row 9 by compressed air, so form powerful spray beam 10, they are also had the ability and will drive away attached to the air layer of the solvent that contains evaporation on the paper web 1 etc.Therefore, infeed among the nozzle row 9 and regulate liquid and compressed air, as representing with supply pipe 11,12.Supply pipe 11 is attached troops to a unit in regulating liquid, and supply pipe 12 is attached troops to a unit in compressed air.
For guaranteeing spray beam 10 canal limitization reliably, set the spray chamber 13 of a cross section roof shape or V-arrangement respectively for nozzle row 9.Drip collector can be installed in the lower end of the wall that 13 roof shapes incline towards each other in the spray chamber, top.Spray chamber 13 is contained in respectively in the aspirating chamber 14 of being correlated with, and aspirating chamber is bled by a ventilation blower 15.The air that prevents to contain liquid thus spills and for example may cause at the drier 2 outside coagulations that form from adjusting device 8.Ventilation blower 15 can be blown in the drier 2, and therefore the fresh air that sucks from the outside mixes with the air of preheating, thereby cuts down the consumption of energy.At each ventilation blower 15 provided upstream cooling unit 16.It plays condenser, so that contained liquid in the separation of air at first contains water, but also may contain silicone and solvent in the liquid.
For setting one respectively, supply pipe 11 or 12 is the flow regulator of valve 17,18 in form.Valve 17,18 is by control or adjuster 19 controls, as schematically illustrating with the holding wire of not representing in detail.Controller 19 is according to different actual values, and for example temperature and/or the humidity of before the adjusting device 8 and back paper webs 1 determine to be applicable to the control impuls of valve 17,18.These actual values are by means of the sensor measurement that does not have further to represent, and via holding wire input controller 19, controller is provided with suitable actual value inlet 20.
Be divided into two parallel branches of leading to a nozzle row 9 who attaches troops to a unit respectively behind the valve 17,18 of supply pipe 11,12 under separately here.But also can imagine, for a corresponding feeding mechanism is established in each nozzle deploying.
Attaching troops to a unit is connected on the compressed air source 21 in valve 18 upstreams in compressed-air actuated supply pipe 12, and for example ready-made compressed air is online.Attach troops to a unit and be connected with a feeding mechanism 22 that is provided with water inlet and silicone mixing arrangement in the upstream of affiliated valve 17 in the supply pipe 11 of conditioning agent.Illustrated for example in, it comprises the pump 23 of a suction side in container 24, container 24 is equipped with in form the needed adjusting liquid for the mixture of having mentioned of being made up of water and silicone, wherein the concentration of silicone is 0.1%-2%.Pump 23 can be controlled by means of the valve 17 that controller 19 is parallel to the downstream, as representing with parallel holding wire.
Though describe a particularly preferred embodiment of the present invention above in detail, should therefore not be restricted.Exactly, for the expert provides a series of possibilities, be adapted to various concrete situations around basic ideas by the present invention program.For example it is also conceivable that like that as already mentioned, adjusting device 8 is arranged in the zone between drier 2 outlet and chill roll frame 3 first chill rolls, or is combined in the chill roll frame 3.Important only is, before paper web 1 leaves the chill roll frame, in any case humidification and silicone-treated are finished jointly by using the mixture of being made up of silicone and water again.
