Description
Technical field
The present invention relates to a kind of as described in the preamblely in claim 1 for the equipment to page spreading powder at printing machine, it comprises: for the tank of powder; For measuring the meter of powder, this meter is connected on described tank; There is the jet rod of powder jet; For powder air mix is assigned to the distributor on powder jet; And connecting line between meter and distributor.
Background technology
In DE4237111B4, described a kind of powder equipment, in this powder equipment, powder stream mixes in spray chamber with pressure air stream.Pressure air stream is supplied to spray chamber by compressor by magnetic valve.
In DE19901245A1, describe a kind of powder equipment, in this powder equipment, in jet pump, powder has been blended in carrying gas flow.Described jet pump can be by means of fan operation.
In DE19902712A1, described a kind of powder equipment, in this powder equipment, air is as carrying gas.Produce the mixture being made up of powder and carrying gas by means of powder gas generator, described powder gas generator has the pipeline being connected on blower fan.
The shortcoming of described prior art is to need independent blower fan or independent compressor.Improve thus manufacturing cost.In addition, independent blower fan Structure of need space, has therefore just lacked described structure space for other devices.
Summary of the invention
Task of the present invention is to provide a kind of powder equipment with saving structure space simple in structure.
Described task solves by the equipment with claim 1 feature.According to the present invention, propose a kind ofly for the equipment to printed sheet spreading powder at printing machine, it comprises: a tank for powder; One for measuring the meter of powder, and this meter is connected on described tank; One has the jet rod of powder jet; One for being assigned to powder air mix in the distributor on powder jet; Connecting line between one meter and distributor, is characterized in that, one is passed into described connecting line for the infeed pipeline that feeds pressure air; One section between described infeed pipeline and described distributor of described connecting line is set to the mixing chamber for pressure air is mixed with powder; And described infeed pipeline is connected on the central pressure air feedway of described printing machine.
The advantage of powder equipment of the present invention is, greatly reduces manufacturing cost.Another advantage is, has saved structure space by cancelling independent blower fan, and the structure space saving can allow other devices use.Attendant advantages is function aspects, because the pressure air feeding can be used to control ration.
Can realize the various expansion schemes of present device.
In an expansion scheme, described tank closely or at least standard seals closely.Avoid thus the leak air from environment.
In another expansion scheme, in described infeed pipeline, integrated one for controlling the control device of pressure air of infeed.Utilize the percolation that described control device can controlled pressure air.
In another expansion scheme, described central pressure air feedway is given the pneumatic type page guiding device supplied with pressure air of described printing machine.That is to say, described central pressure air feedway not only for give powder supply of equipment pressure air, and simultaneously for give pneumatic type page guiding device supplied with pressure air.
Accompanying drawing explanation
By draw in other structure to preferred embodiment and the description of the drawings below and function on favourable expansion scheme.
Fig. 1 illustrates the sketch plan of printing machine, and described printing machine has page collector and is arranged on the powder dispenser in page collector,
Fig. 2 illustrates the detail view of powder dispenser.
The specific embodiment
Fig. 1 illustrates the printing machine 1 with printing equipment 2 to 5 and page collector 6.Page collector 6 comprises chain conveyor 7, and described chain conveyor is placed on printed sheet to collect and stacks on 8.In addition, printing machine 1 also comprises turn-over rig 9, and described turn-over rig can be switched to obverse and reverse printing mode from pure printing mode.In pure the printing mode that does not make page turn-over, printed sheet not only prints in being arranged in turn-over rig 9 printing equipment 2 and 3 above but also being arranged on turn-over rig 9 printing equipment 4 and 5 below on page front.In obverse and reverse printing mode, in the printing equipment 2 and 3 of printed sheet above, on page front, in printing and printing equipment 4 and 5 below, on the page back side, print.Powder equipment 10 is set in page collector 6, and described powder equipment is carried the printed sheet spreading powder of coming by chain conveyor 7.In addition, page guiding device 25 is set in page collector 6, described page guiding device guides page during carrying page by chain conveyor 7.For this reason, page guiding device 25 produces the winding-up mattress of carrying page.Page guiding device 25 pneumatically acts on and is equipped with winding-up nozzle.
In order to give page guiding device 25 supplied with pressure air, described page guiding device 25 is connected on the central pressure air feedway 11 of printing machine 1.Other pneumatic type page guiding device and other customers of printing machine 1 on described central pressure air feedway 11, are connected with, other customers of described other pneumatic type page guiding device and printing machine are arranged in printing equipment 2 to 5, but not shown.On described central pressure air feedway 11, also connecting an other printing machine.
Fig. 2 illustrates, powder equipment 10 comprises a tank 13 with lid 14.In described tank 13, have powder deposit 15, described powder deposit is measured in meter 16.Described tank 13 is connected on the bottom of shrinking of described tank 13 for infundibulate or taper and described meter 16.Powder deposit 15 forms and piles up post and enter into meter 16 by gravity at described tank 13.
Described connecting line 18 is connected described meter 16 with a distributor 21.In the region of a pipe section 20 of described connecting line 18, one feeds pipeline 19 and is passed in described connecting line.Described infeed pipeline 19 is connected on the central pressure air feedway 11 of printing machine 1 by control device 12.Can make the volume flow that is fed to the pressure air in connecting line 18 by feeding pipeline 19 change by means of control device 12, for example, change by means of adjustable throttling arrangement.Described pipe section 20 forms a mixing tube, in this mixing tube, from feed pipeline 19 pressure air with mix from the powder of meter 16.
The air mixture of powders forming in connecting line 18 flow in distributor 21, and in this distributor, the total stream of mixture is divided into multiple mixture subflows.Each subflow flow to powder jet 23 or powder jet group by the feeding pipe 24 of oneself from distributor 21.Powder jet 23 is in a row to be arranged on jet rod 22, and described jet rod is ejected into by described chain conveyor 7(air mixture of powders referring to Fig. 1) carry in the page of coming.Distributor 21 is connected with jet rod 22 by the tube bank of described feeding pipe 24.Described feeding pipe 24 can be configured to flexible flexible pipe.
This system seal closely by described lid 14 in addition, thereby the air that makes to be included in the air mixture of powders of formation only comes from described central pressure air feedway 11 and do not comprise the leakage rate with other approach suctions.Under many circumstances, accurate tight sealing is also enough.For the air total amount C being included in the air mixture of powders that is supplied to distributor 21, thereby air amount A comes from and feeds pipeline 19 and come from central pressure air feedway 11 and air amount B is not from central pressure air feedway 11, but come from tank 13 or meter 16 or come from the opening that feeds pipeline 19 tops that is present in pipe 18.Air amount B is for example leaked air quantity, and described leaked air quantity flows in the situation that lid 14 does not seal completely airtightly.C=A+B。In the case of the system of tight seal: B=0%.For example, in the case of the system of accurate tight seal: B<50%, preferably B<20%, B ≈ 10%.
On powder jet 23, air mixture of powders has approximately 10 nozzle exit pressures to 35mbar.This can utilize the supply pressure of the approximately 193mbar of central pressure air feedway to realize.Do not need independent for the blower fan to powder supply of equipment pressure air.
