Description

The paper guide of rotary press paper pile
The present invention relates to the paper guide that a kind of rotary press paper pile is used, to the paper out of the press that comes out from the final stage printer, rely on the grippers and the paper feed sheet thereof of running on the ring chain, it is moved to the one or more brake rollers that are contained on the paper guide, rely on brake roller to make its brake also and then be deposited on the pile, simultaneously be provided with the guide plate that is contained in below the chain, at guide plate with lead to and also be provided with tangent between the brake roller of horizontal segment but with to lead the paper direction opposite with guide plate in the ascent stage of paper guide, lead the bow diffuser along what the paper guide Width was equally spaced.
The paper guide of this class is disclosed in German patent application DE-OS31 13 750 A1.
When the chain that dependence has a grippers moves paper above guide plate, because aerodynamics can form air cushion layer by nature between guide plate and paper.Concerning the positive back face printing product, additional air cushion can prevent that guide plate from contact bluring of also causing therefrom with the one side of new printed paper.By be located between guide plate and the brake roller leading the bow diffuser can below paper, blow afloat one tangent with guide plate but with leading the paper direction opposite air-flow.Because this strand air-flow is leading to the negative pressure that is caused in the paper section of leading of leading the bow diffuser, paper is drawn towards brake roller, not only can make broadside and broadsheet is stacked reposefully with the brake roller braking.But air blowing can make the air cushion layer thickening of being equipped with above the guide plate of leading the bow diffuser.
At this moment air-flow changes turbulent flow into from laminar flow, and unexpected flow-disturbing can take place air-flow, forms an air cushion layer that expands under high velocity air, and becomes the unstable state that becomes with situation thus, and can cause that paper swats when being pulled.Its consequence is on broadsheet out of the press blooming to take place.It is correspondingly also unstable when air-flow generation flow-disturbing to lead the negative pressure that produces around the bow diffuser, thereby can not reposefully paper be delivered on the brake roller, and consequently not only broadside but also broadsheet all the braking problem can take place.
Simultaneously the flow-disturbing of air-flow also with the annularly flow speed of paper, and the performance index of paper, for example weight, roughness of surface etc. are relevant.The flow-disturbing phenomenon of air-flow also can take place under circlet shape flowing velocity for light and shaggy paper.
Task of the present invention is exactly to develop a kind of this class paper guide that is used on the rotary press paper pile, paper can be braked on brake roller reposefully, and paper is balancedly carried.
According to the present invention, this task is to solve like this, promptly is provided with and leads the bow diffuser along leading the paper direction on the top of guide plate, and guide plate is made into orifice plate and is distributed with air suctiton ventilator along the orifice plate Width under orifice plate.
Be provided with the section of leading the bow diffuser because the air cushion layer thickeied of blowing can make it to leave orifice plate and partly be sponged by air suctiton ventilator, so the air cushion layer on orifice plate has just reduced.By the minimizing of air cushion layer, at this paper taking place especially easily swats leading in the paper section of phenomenon, between orifice plate and paper, change the harm of turbulent flow and swatting phenomenon and all can greatly reducing of paper into from laminar flow.
For broadsheet, paper will be evenly and reposefully on air cushion layer by carrying-off and the guide plate of getting along well contact.The following of printed paper just can not darkened.For broadside, can use air suctiton ventilator and as much as possible air cushion layer be taken away, paper on the orifice plate can be directed into reposefully fast lead before the bow diffuser.
No matter be broadside or broadsheet, can in its contiguous affected scope, the air cushion layer that weakens be moved reposefully always lead the bow diffuser.The result can cause a stable negative pressure near the diffuser and paper is attracted on the brake roller safely leading bow.
No matter be broadside or broadsheet, all available paper guide of the present invention safely and do not have the back to back brake roller of blooming ground guiding and brake with it.The delivery of paper is to rely on above-mentioned air suctiton ventilator to make the different desirable delivery condition of broadside and broadsheet can obtain simply adapting to by regulating air cushion layer.
The harm that paper is swatted and can make their further minimizings by means of the way of the guide plate of the middle part of delivery paper and compresses lower section also being made orifice plate because high speed printing itself adds the natural air cushion layer of generation thereby the blooming that causes.At this moment the air cushion layer that a part oneself produces can run away by the eyelet on the orifice plate.
For further improve the air suctiton ventilator of embarking on journey that adapts to press speed and in orifice plate, set up below the lower curtate by the ability of printed material material can accomplish light and coarse paper under high speed printing also can satisfy respectively broadside and broadsheet requirement and by the transportation section of the next straight line that leads safely.
Below straight line rising conveyor zones orifice plate, can be divided into an independent induction chamber, an independent air suctiton ventilator is set, air cushion layer is regulated easily, improve the conveying of paper with wallboard.
