Description
The present invention relates to be used in web press, the cleaning system of the coiled strip deflector roll (after this being called " deflector roll ") of paper interpreter, textile printing machine etc. is applicable to that particularly cleaning is bonded at the guide roller cleaning method and the equipment of the stain of many guide roller surface (resembling printing ink and other dirt).
In the equipment that is applied to such as technical fields such as web printing technology, paper switch technologies, a plurality of deflector rolls are installed by predetermined direction.By means of the example of as shown in Figure 4 newspaper web press, these deflector rolls will be described.
In common printing operation, be guided the impression cylinder 6 of printing 5 by many deflector rolls 4 from the roll web 3 of paper roll 2 feed of paper feeding platform 1.When pressing impression cylinder 6 with rubber cylinder 7, the printing-ink on from plate cylinder 8 voltage supply to rubber cylinder 7 just is transferred on the roll web 3.The roll web that printed is guided by many deflector rolls, and by carry-over pinch rolls 9 tractions, it is folding to be folded machine 10 at last again.After this, roll web is transmitted the device (not shown) and is fed to other operation.
Along with the carrying out of printing operation, deflector roll is printed printing ink and dust is stained gradually.When printing was carried out in this state, the stain on the deflector roll just was transferred to the surface of printed matter, thereby reduced product quality.Thereby under the situation of newspaper web press, printing operation must be interrupted, with the stain on the cleaning deflector roll.In clean operation, oil or analog absorb because waste material is cleaned, and each deflector roll is manually cleaned.
On the other hand, the deflector roll automatic cleaning equipment has been proposed.For example, according to disclosed deflector roll automatic cleaning equipment in Japanese patent laid-open No. sho 62-149449, the rotation of deflector roll is controlled by a revolution speed control device, so that there are differences between the rotation round speed of deflector roll and the roll web gait of march, the roll web and the slip between deflector roll that produce owing to speed difference can make guide roller surface be cleaned by roll web.
In addition, according in Japanese patent application publication No.: disclosed another deflector roll automatic cleaning equipment among the flat 4-21445, first liquid is coated on the roll web part surface, with dissolving and/or the softening stain layer that sticks to guide roller surface, to being had second liquid that absorbs transfer characteristic to be coated on the remaining surface (except that being coated with first liquid surface) of roll web by dissolving of first liquid and/or softening stain layer.After this, the surface that is coated with first liquid contacts with guide roller surface, with the stain layer on dissolving and/or the softening deflector roll, dissolved then and/or stain layer that is softened and lip-deep second liquid that is coated with second liquid react, absorbing and to shift the stain layer to roll web, thereby cleaned deflector roll.
Have successively in the such machine of the newspaper web press that surpasses 100 deflector rolls resembling, cleaning each deflector roll is sizable work, and the clean operation of eminence deflector roll is existed danger.And deflector roll may be arranged in the out of reach place of operator or be arranged in too narrow place and can not implement clean operation, therefore, also has problems in operability and secure context.
In addition, common deflector roll automatic cleaning equipment needs roller driving mechanism and arrestment mechanism, between paper and deflector roll, to produce a speed difference, it also need compensate the deviation of paper power, this is to be easy to take place because paper force unbalance meeting is blocked paper, like this, the operability of equipment and structure just complicate.In addition, go back the variation control solvent supply operation of fibrous root, thereby need comprise the control device of solvent supply operating control procedure according to deflector roll rotary speed and roll web motion.
In addition, in using the method for two kinds of cleaning solutions, need a plurality of cleaning solution feeding mechanisms, between each cleaning solution feeding mechanism, need operation timing, promptly must and stain two kinds of cleaning solutions of situation control and be fed to state on the roll web according to the driving situation of machine.Thereby control device is complicated and expensive.
The purpose of this invention is to provide a kind of guide roller cleaning method and equipment, when it can produce a relative speed difference between roll web and deflector roll, automatically clean deflector roll with high operability and low cost.
In order to achieve the above object, Web guide roller cleaning method according to the present invention is characterised in that and may further comprise the steps: adhesive is applied to web surfaces, so that remove printing ink and other dirt from guide roller surface; The roll web that scribbles adhesive is contacted with guide roller surface, with adhesively with printing ink and other soil transfer to the roll web that scribbles adhesive, thereby the cleaning guide roller surface.
In addition, the roll web cleaning equipment that is used to clean one group of deflector roll is disposed in the path of roll web, and it comprises: be used for adhesive is applied to an adhesive coating device of web surfaces, to remove printing ink and the crud layer that pollutes guide roller surface; Wherein adhesive coating device is disposed in the upstream of the deflector roll that is cleaned.
Preferablely be: because adhesive is a kind of material that oleaginous material is had viscosity, guide roller surface is with there being the material processed of low-surface-energy, or stands certain processing and have meticulous not plane.In addition, after crossing the last roller of the guide roller set that is cleaned at roll web, the adhesive of roll web suffers a kind of like this processing, with prevent from adhesively to be transferred to stain on the roll web adhesive transferred to again the last roller that is positioned at guide roller set the downstream and with member that the roll web adhesive contacts on.
A kind ofly like this prevent that the processing shifted again can be by scribbling adhesive surface on the roll web and realize scribbling on the roll web that adhesive surface provides a noncohesive characteristic or covering with cohesionless material.
According to the present invention, when the low-speed handing by machine was advanced roll web at leisure, adhesive coating device was driven, to be coated with the adhesive of a predetermined length in the web surfaces that will contact with deflector roll.When the web surfaces that scribbles adhesive arrives deflector roll, during roll web is advanced along guide roller surface, stain layer on the deflector roll contacts with the adhesive on the roll web, ink lay on the deflector roll is adhered to the web surfaces that scribbles adhesive, when roll web separates with deflector roll, the stain layer just is transferred on the roll web, thus the cleaning deflector roll.
