Abstract
The invention relates to a device for spraying power on a printing material in a printing machine, wherein both the front and the back of the printing material are dusted with powder. The device is characterized in that the front and rear nozzles are supplied from a common dosing unit and a common first distributor, and powder is firstly input in the first distributor, wherein one or more second distributor for the front nozzle are connected to the first distributor, and one or more third distributor for the rear nozzle are connected to the first distributor.
Description
Technical field
The present invention relates to the powder device of preamble according to claim 1.
Background technology
As at US7, the powder device as described in 942,096B2 is used for printed pages dusting end, therefore makes in the sticky adjacent printed pages of rubbing in collection heap of the fresh ink in printed pages.
Described powder device has a line nozzle head, and powder air stream sprays from described nozzle head, so as powder to be applied to through page on.
In general, the front of described printed pages is loaded powder air mix at this by from above.
The problem of this collection process is, page is always not stacked up and down completely overlappingly, but remains in missing one another on collection heap.This makes the transport of pile become difficulty and can cause the plastic deformation of printable fabric fringe region.Another shortcoming occurred in collection process is set-off.At this, fresh dimensional printed chart is damaged by the motion being placed on the page on dimensional printed chart.
DE3217779A1 discloses a kind of paper receiver of printing machine, can arrange two powder devices in described paper receiver.First powder device from towards the front dusting end of printed pages and the second powder device under towards the dusting end, the back side of printed pages.
The two-sided dusting end of printed pages has some advantages.Therefore, when the page leaving printing machine arrives, by additionally producing in the page placed so-called " ball bearing effect " to page back side dusting end, described ball bearing effect pro affects page and slides on each other.This causes the improvement of the flatness of page.Therefore, it is possible to realize higher stacking highly.
In addition, described " ball bearing effect " contributes to the danger reducing set-off.
But according to current prior art, described advantage brings with the cost of costliness because (as described in DE3217779A1 and shown) powder device of two the whole series must be used.
Summary of the invention
Therefore, task of the present invention is, reduces and is used for the manufacturing cost of the powder device at the two-sided dusting end of printable fabric.
According to the present invention, this task is solved by the powder device with the feature of described claim 1.Page by nozzle from above and from dusting below end.Front nozzle and back side nozzle are by unique public metering unit and the first public distributor supply.This realizes with following form, that is, first described powder is exported to described first distributor from metering unit.Described powder dispense is given again at least one second distributor and at least one the 3rd distributor by described first distributor, and at least one second distributor described and at least one the 3rd distributor are connected on described first distributor.Then, described front nozzle supplying powder given by least one second distributor described.Described back side nozzle supplying powder given by least one the 3rd distributor described.
In a favourable embodiment of the present invention, the quantity of described second distributor is greater than the quantity of described 3rd distributor.Why this meets object requires, is because the distribution ratio of described powder air mix is very different when loading described powder air mix from above when loading described powder air mix from below.In order to make full use of the advantage improved flatness and reduce set-off, a small amount of powder is also enough.
In another favourable configuration of the present invention, the quantity that the number ratio being connected to the back side nozzle on corresponding 3rd distributor is connected to the front nozzle on corresponding second distributor is many.
Thus, be reduced compared to the amount of powder sprayed from front nozzle from the amount of powder of back side nozzle ejection, and independent adjusting device need not be used.
According to a particularly advantageous configuration, 12 second distributors respectively with three front nozzles and two the 3rd distributors respectively with six back side nozzles are connected on described first distributor.
Another favourable configuration of the present invention designs like this, and described first distributor is to this second distributor or these the second distributors and can be opened and closed to the outlet of this 3rd distributor or these the 3rd distributors.Therefore, such as, single distributor can be turned off in printing compared with during small dimension, to avoid wasting powder.
In another favourable form of implementation of the present invention, the amount of powder being exported at least one the 3rd distributor described by the first distributor is independently conditioned in the mode more than two-stage by means of the control unit between described first distributor and at least one the 3rd distributor described and the amount of powder exporting at least one the second distributor described.
According to another favourable form of implementation of the present invention, between described first distributor and this or these the 3rd distributor, throttling arrangement is set respectively.Therefore, the amount of powder exported by described back side nozzle is compared the amount of powder exported on the nozzle of described front and is reduced.
In another favourable form of implementation of the present invention, the amount of powder that described back side nozzle exports is only the mark sub-fraction in other words of the amount of powder exported on the nozzle of described front.
Particularly advantageously, the amount of powder described back side nozzle exported is only 20% of the amount of powder exported on the nozzle of described front.
In the configuration that another is favourable, design the distribution of described powder at least one second distributor described and at least one the 3rd distributor described like this, it independently can be conditioned with carrying air stream.
Accompanying drawing explanation
Shown in the drawings of the powder device at the page dusting end given in the paper receiver of printing machine.
Detailed description of the invention
Show printing machine 1 partly in the drawings.Described printing machine 1 is the lithographic offset press for printed pages 2.Illustrate in described local to the powder device 3 at the page 2 dusting end in the paper receiver of described printing machine 1.First described powder is arranged in metering unit 4.Described metering unit 4 comprises the powder dosage roller in powder storage device and downstream.Be exported to the first distributor 5 from powder there.Then described first distributor passes through outlet 10 by powder dispense on multiple second distributor 6 and multiple 3rd distributor 7.Have respectively between described first distributor 5 and described 3rd distributor 7 and by the throttling arrangement 9 of step-less adjustment, can independently regulate exportable amount of powder with front nozzle 8.1 by means of described throttling arrangement.Described powder is exported to from described second distributor 6 on described front nozzle 8.1 and described powder is exported on back side nozzle 8.2 from described 3rd distributor 7, and then described powder is sprayed onto in described page 2 by described nozzle.
