Symbolically illustrate a kind of for the layout at dust collecter 1 place supply suction air in FIG。Dust collecter 1 arranges as a part for paper-processing machine and such as can be used for paper separation printing material paper B in the stacks of sheets from feeder in paper press at this。For this dust collecter 1 together with different types of operating mechanism 2, as being used for separately and the aspirator transported, running with the work tempo of paper-processing machine, it is for further processing that the printing material paper B thus separated from stacks of sheets can be forwarded to paper-processing machine with meeting beat from dust collecter 1。The operating mechanism 2 being configured to by aspirator has shell, and in shell, a piston can move up and down, in order under the effect of the negative pressure of suction air, aspirator is risen to operating position from holding fix after catching a printing material paper B。

Dust collecter 1 is assigned different types of operating mechanism 2 in the case movingly, and wherein, they can differently be configured to by aspirating mechanism or by blower mechanism。Best operating mechanism 2 is by separately or promote aspirator or be also configured to by drawing or transport aspirator。Operating mechanism 2 arranges with dust collecter 1 via different drive mechanisms in addition with being connected。

In addition in order to the air of operating mechanism 2 supplies, dust collecter 1 is assigned at least one suction air generating system with at least one ejector 3, this system with one, multiple or whole aforesaid operating mechanism 2 is connected。

Ejector 3 runs with pressure air according to the principle of suction jet pump to supply suction air, and wherein, pressure air passes through nozzle guide, arranges pneumatic fitting on the position that it is the narrowest。If below speaking of pressure air, always refer to the pressure air of blowing air form at this。

First, at the first pneumatic fitting 3.1 place, under the control via the first magnet valve 4, in conveying runs, pressure air is fed into ejector 3 by the first pressure air pipeline 5。Magnet valve 4 is that this pressure air supply source 7 commonly known with one is connected。It is online that this pressure air supply source can be connected to pressure air in the operation making paper-processing machine run。Can also arranging special pressure air supply source, it has the independent pressure air generator for ejector。

Ejector 3 is connected via suction air line 6 and dust collecter 1 or its operating mechanism 2 one or more at the second pneumatic fitting 3.2 place, and wherein, this operating mechanism is now configured to aspirating mechanism。In known manner, ejector 3 connects suction air line 6 in the region of the through-flow narrow positions of pressure air。Flowing by pressure air acceleration in narrow positions, air pumps out from suction air line 6 and is arranged in the end of suction air line 6 by this way via suction this operating mechanism of air line 6(in operating mechanism 2 as suction air consumption device) produce negative pressure and in operating mechanism 2, thus produce suction air flow, this suction air flow acts on its outside work surface。

In order to discharge at this/these operating mechanisms 2 or this/pressure air that uses in ejector 3 when producing suction air of these customer places, the 3rd pneumatic fitting 3.3 place on ejector 3 arranges air outlet slit 13, and this air outlet slit is furnished with silencer element and/or can also use valve control。Therefore at air outlet slit 13 place, pressure air under pressure reduces and using this/volume that increases of the air of these customers suction under as flowing out with controlled blowing air-flow if desired by noise reduction。

First magnet valve 4 is connected with suction air line 6 via the second blowing air line 8 in addition, wherein leads in suction air line 6 at line branches 9 place in the second blowing air line region between ejector 3 and dust collecter 1。First blowing air stream controlled is supplied dust collecter 1 by the second blowing air line 8 on this path in the region of suction air line 6。

At this it should be noted that at switching magnet valve 4 to be supplied to by pressure air in suction air line 6 via pressure air pipeline 8 period, simultaneously close off the air intake of the pressure air pipeline 5 led between magnet valve 4 and ejector 3 on magnet valve 4。Therefore comprising the pressure air of certain surplus in this case in pressure air pipeline 5, it is merely able to produce at the same time via ejector 3 to eliminate gradually under suction air in suction air line 6。Therefore this suction air followed is eliminated gradually equally via pressure air pipeline 8 under the control by magnet valve 4。Therefore be possible to prevent in its simplest form, the suction air followed can also particular up to this/these operating mechanisms 2 or this/these customers。

In addition additionally via the second magnet valve 10 supplied with pressure air, dust collecter 1 can be supplied another in check blowing air stream。For this second magnet valve 10 via the 3rd dry air line 11 in ejector 3 and dust collecter 1 this/region between these operating mechanisms 2 or customer in be connected with the line branches 9 in aspirating air line 6。

Two magnet valves 4 and 10 can jointly and independently of each other run by means of valve control device 12。Coupling at this this valve control device and a control computer, the angular signal of paper-processing machine is fed into this control computer。Thus can implement the pressure air of ejector 1 is supplied by controlling magnet valve 4,10 according to the work tempo of paper-processing machine according to the angular signal of paper-processing machine with thus。

Now run duration by means of the first magnet valve 4 with the beat of paper-processing machine for this/the blowing air supply that adjusts targetedly of these suction air consumption devices 2。Thus dust collecter 1 to separate printing material paper B in the beat of the paper-processing machine such as stacks of sheets from feeder and can flow to paper-processing machine。

In the case, the pressure air stream controlled by magnet valve 4 is supplied to ejector 3, thus the correct moment and on the correct persistent period by aspirate air line 6 dust collecter 1 this/these operating mechanisms 2 on apply the negative pressure of each requirement, printing material paper B can be held via such as one or more aspirators whereby。

In a time delay corresponding with this, the supply of pressure air is interrupted by magnet valve 4, so that drop in suction air line 6 and this/these suction air consumption devices or the negative pressure at place of operating mechanism 2 and the printing material paper B that is booked can discharge by the operating mechanism 2 being such as configured to aspirator, for further processing。Negative pressure in order to ensure at place of operating mechanism 2 is positively eliminated in time and thus printing material paper B is positively released, and the second blowing air line 8 implementing into pressure air bypass is supplied to pressure air pulse at the first magnet valve 4 place。By this way a moment, during it, the air pressure in the first pressure air pipeline 5 leading to ejector 3 is also being reduced, in the thus also lasting negative pressure stage ejector 3 and dust collecter 1 this/these operating mechanisms 2 between realize pressure balance。The printing material paper B being thus transferred can be caught by temporally precise and discharge。

In order at very high operating rate and the running parameter also improving such dust collecter 1 under the very short working cycle related to this, it is stipulated that with the first magnet valve 4 independently by the second magnet valve 10 supply pressure air to suction air line 6。Thus can earlier and more accurately use, via the 3rd air line 11 of drying, the pressure air stream controlled targetedly, for interrupting at this/these operating mechanisms 2 or this/negative pressure at these customer places。The effect of the pressure air stream being controlled ground output by the first and second magnet valves 4,10 can be mutually combined and correspondingly mutually coordinated, in order to realizes the maximum transmission capacity for dust collecter 1。

To the control of suction air flow can in dust collecter 1 additionally pneumatic control device 22 by means of control roll form known per se implement。It is connected at this/the suction air path of suction air line 6 between these operating mechanisms 2 or customer in。Controlling the valve system that roller is a kind of rotation, it and machine are synchronously driven and are exported based on the release of machine corner or occluded air via controlling opening。Can realize designing previously given air supply by its valve mechanically determined by means of controlling roller。Can also realizing for the air air supply with the combination of suction air of drying by means of controlling roller, thus whole customers of dust collecter 1 can control by middle ground。When configuration controls roller, the suction-and/or the blowing air that produce by means of one or more ejectors 3 be used to promptly, local and produce to use air in place to use homoiothermic。For reducing at this/the blowing air line 8,11 of the negative pressure at these places of operating mechanism 2 can be connected with suction air line 6 before or after pneumatic control device 22。

Fig. 2 symbolically illustrates the layout for supplying suction air of a kind of Fig. 1 of corresponding essentially to, and wherein, printing material paper B should be caught by the operating mechanism 2 that is constructed by aspirator。

Dust collecter 1 is also assigned a suction air generating system with ejector 3。Ejector 3 is connected with pressure air supply source 7 via the first magnet valve 4。Being ejector 3 supply pressure air by pressure air supply source 7, wherein, pressure air supplies via the first pressure air pipeline 5 as in check blowing air stream via magnet valve 4。Ejector 3 is connected by the operating mechanism 2 that can be configured to aspirator with one or more via suction air line 6 on the other hand。In ejector 3 also by way of the pressure air the existed suction air line 6 to being connected on pneumatic fitting 3.2 by the flowing supply suction air accelerated and this/these operating mechanisms 2 or customer in produce negative pressure。

First magnet valve 4 is connected with suction air line 6 via the second air line 8 of drying in addition, wherein the second blowing air line 8 the ejector 3 of dust collecter 1 and this/these operating mechanisms 2 between region in pass at line branches 9 place and to aspirate in air line 6。Therefore blowing air stream can be supplied to dust collecter 1 by the second blowing air line 8 on this path in suction air section。

With the beat of paper-processing machine, ejector 3 is carried out pressure air targetedly by means of the first magnet valve 4 at run duration to supply。So constructing magnet valve 4 for this, namely can implement a kind of connection, wherein, the blowing pneumatic fitting 4.1 leading to pressure air supply source 7 is connected with the blowing air outlet slit 4.2 leading to blowing air line 5。Then blowing air outlet slit 4.2 couples with ejector 3 via blowing air line 5 and supplies in check pressure air stream to ejector。Thus dust collecter 1 can via ejector 3 controllably to separate printing material paper B and to flow to paper-processing machine in the beat of paper-processing machine stacks of sheets from feeder。

In the case ejector 3 is supplied respectively to a blowing air draught, thus the correct moment via the suction air line 6 on dust collecter 1 this/these operating mechanisms 2 in apply negative pressure, can catch by means of one or more operating mechanisms 2 constructed by aspirator whereby, separate (separating) and/or carry each independent printing material paper B。

One with in this previously given time delay, one separately-and/or interrupt the supply of pressure air from the first magnet valve 4 to ejector 3 when conveying beat terminates。Carry out continuing conveying to discharge printing material paper B, it is necessary to interrupt in dust collecter 1 this/negative pressure at these places of operating mechanism 2。In order to can interrupt in time at this/negative pressure at these places of operating mechanism 2 and from this/these operating mechanisms 2 discharge the printing material paper B being booked, for further processing, ensure, this/negative pressure at these places of operating mechanism 2 is positively timely released and eliminates to the full extent。The the second blowing air line 8 implementing into blowing air bypass for this is directly connected with the blowing air line 5 leading to ejector 3 at the first magnet valve 4 place。By changing magnet valve 4, the air under stress also stored in this line sections of blowing air line 5 before ejector 3 is directed in blowing air line 8 as blowing air pulse。By this way when identical when, during it, the blowing air pressure in the first blowing air line 5 leading to ejector 3 is also being reduced, and realizes pressure balance in the thus also lasting negative pressure stage between the ejector 3 of dust collecter 1 and operating mechanism 2。For this reason, the air under stress in blowing air line 5 can not also continue to produce suction air at suction air outlet slit 3.2 place in ejector 3。Additionally, it is directed into via line branches 9 in the first dry volume of air (amount) of also existing under stress in air line 5 and aspirates in air line 6 by the second air line 8 of drying and reduce the negative pressure that there is also there rapidly。The printing material paper B thus carried can accurately be caught by the time and discharge。

In this embodiment can also for ejector 3 the air outlet slit 13 arranged downstream pneumatic control device 22 in blowing air line 6, the suction air flow that can flow out with the rhythm control of paper-processing machine whereby on the side of blowing air outlet slit。For reduce (elimination) this/the blowing air line 8 of the negative pressure at these places of operating mechanism 2 can be connected with suction air line 6 before or after pneumatic control device 22。

Figure 3 illustrates the use of the blowing air existed in the exit of ejector 30。Ejector 30 as front for Fig. 1 describe be supplied to pressure air and produce negative pressure by air suction, this negative pressure can be caught at operating mechanism 2 or customer place for suction and transport printing material paper B selectively。Also blow except the pressure air supplied via magnet valve 40 at air outlet slit 13 place of ejector 30 in the case by ejector 30 suction air intake 3.2 and if desired by this/these operating mechanisms 2 or this/these customers aspirate air stream。Therefore forming the blowing air stream of a kind of combination, it flows out at air outlet slit 13 place of ejector 30。The blowing air stream of this combination at air outlet slit 13 place is characterized by the pressure reduced after injector channels and the volume increased by the volume of air to be sucked on the other hand on the one hand。

The blowing air stream of this combination is tempered for environmental condition there by the setting of the swabbing action of the air part of suction in the region of dust collecter 1。Therefore the blowing air stream flowed out at air outlet slit 13 place of ejector 30 is best suited for the paper at dust collecter 1 place separately。This effect thus provides, and namely blowing air stream has the characteristic and therefore and do not have excessive temperature and humidity difference between the printing material paper B to process of the room air in the environment of the stacks of sheets in the feeder of paper-processing machine to the full extent。

In order to use this blowing air stream, it is shown here at special embodiment。At this for ejector 30 arranged downstream pneumatic control device 22 at the air outlet slit 13 of blowing air line 23 on the side of blowing air outlet slit, the blowing air stream that can also flow out with the rhythm control of paper-processing machine whereby。Pneumatic control device 22 can also construct in the way of controlling roller。Control valve control device that roller is configured to machinery, that drive with the beat of paper-processing machine。Blowing air controls to implement into without pneumatic control device 22 and now be controlled based on machine beat only by the controlling organization by means of magnet valve 40。

In check blowing air stream can regulate with being also attached on its volume and pressure。That be tempered and with work tempo with then supplied one or more operating mechanism 24 if desired either individually or in combination according to the controlled blowing air stream of its pressure and volume, in the paper at the end face place of its stacks of sheets being arranged in feeder for dust collecter 1 as blowing air consumption device region separately。The uppermost printing material paper B of (separating) stacks of sheets is opened on the region of the lateral edges S of the directed in the case stacks of sheets of blowing air stream and there for fan。Printing material paper B thus can be easier to and be separated from each other more reliably。In addition blowing air stream can also be directed into below a printing material paper B separated with the end face of stacks of sheets, and thus this paper has the support air pad of the end face relative to stacks of sheets and thus can reliably transport on the direction of paper-processing machine。In the case, blowing air stream can also at various physical quality (pressure, temperature, volume) under (stagger ground) separately and is supplied to the identical operating mechanism 24 for not same-action or blowing air consumption device at paper in one or more different working cycle during sheet conveying with it lingeringly in time。

For example, being in period 1 section in the operating mechanism 24 as blowing device effect, the short blowing air draught of a pressure with raising can as so-called separate out air for loosening the uppermost printing material paper B being positioned on stacks of sheets in advance。Another improvement of air supply is figure 5 illustrates for this。

An operating mechanism 24 or blowing air consumption device place or utilize two kinds of methods of operation of Liang Ge operating mechanism 24 or specific air consumption device of drying to be implemented by the air of the homoiothermic at machining location, thus the processing of paper can to the whole material special protections to process of printing material paper B and be advantageously carried out。

Schematically illustrate the device of the combination according to Fig. 2 and 3 in the diagram。Being shown in which a kind of dust collecter 1, device not only has the operating mechanism 2 of aspirator form, and has the operating mechanism 24 of blowing apparatus form。The operating mechanism 2 being configured to aspirator in the case herein is assigned ejector 3 in the above described manner, is used for for 3 times producing suction air at connection magnet valve 4 and ejector。In addition multiple operating mechanisms 24 being configured to blowing device are assigned ejector 3 in the above described manner, for connecting magnet valve 4 and 3 times generation blowing air of ejector。In the way of having been described above, with this diagram differently, also for the air supply source via ejector 3 of each operating mechanism 2,24 illustrated distribution one oneself。A common air supply source via ejector 3 can also be distributed equally for the different operating mechanism 2 for aspirating air process。One common controlling organization 12 for whole air supply systems being connected with magnet valve 4 is set in the diagram。But at this it should be noted that at least one party faces and produces suction air and the magnet valve 4 on the other hand requiring at least one independent respectively for producing blowing air produces for the separate respective air of control。

Additionally, the pneumatic control device 22 arranged for producing the blowing air in Fig. 4 can be configured to the control roller driven with machine beat as has been described。But in another embodiment, as pneumatic control device 22, it is also possible to arrange one be applicable not only to control to this/these operating mechanisms 2 suction air supply and also to this/these operating mechanisms 24 blowing air supply public control roller。Control roller now receive by suction air line 6 and the control air in passage separately supplied by blowing air line 23 and in each correct moment with in each correct persistent period, they be relayed to operating mechanism 2,24 with controlling。In addition can remove controls roller and its function can substitute only by the controlling organization of magnet valve 4。

The same with the mutual relation for the embodiment according to Fig. 1 and 2 when seeing Fig. 3, about Fig. 4 it should be noted that be not located at the interruption of the blowing air stream at place of operating mechanism 24。This is applicable, because not only loosening the function of paper from the lateral edges of stacks of sheets but also the generation of support air below an elevated printing material paper B or support air pad is not with as the mode separated and carry of printing material paper B, time requirement is strict。On the other hand, must accurately implement with machine beat with conveying separating of printing material paper B。

Schematically illustrate the air-controlled device of blowing for improving according to Fig. 3 in Figure 5。In the case can the identical operating mechanism 24 as blowing device effect be in the second segment of a working cycle to arrange another less pressure and the volume with increase, the blowing air draught that for transporting promotes printing material paper B, its as so-called support air at a printing material paper B support air pad generated below risen from the surface of stacks of sheets。One air generating device for air of drying according to Fig. 3 is set for this, wherein passes through to dry air line 5 to ejector 3 on-load pressure air by means of magnet valve 4。By the joint of the blowing air line 23 at air outlet slit 13 place at ejector 3, the air stream exported there is fed into one or more operating mechanism 24。These operating mechanisms 24 are configured to so-called support air hair-dryer, in order to from stacks of sheets side S separated and be sucked blow air below the printing material paper B that device rises at its trailing edge。In the case to consider impact, namely printing material paper can have more than 0.75qm(square metre) extend and therefore support air is firstly the need of certain energy, to reach the whole surface below printing material paper B。Therefore need in the first phase there is smaller size smaller but the air stream of the pressure improved, to meet the function reaching whole paper surface。If printing material paper B is now delivered up by other aspirator side at paper-processing machine in its plane, then in order to carry paper to must be maintained at the support air pad below printing material paper B as well as possible。Other support air is advantageously required again for this, but during now printing material paper B does not allow access into and waves。Therefore in this moment, if printing material paper B starts to travel forward, then the air stream of the volume with increase but less pressure can be carried。

Therefore specify so to design the generation of the blowing air implemented by means of the first ejector 3, namely controlling organization 12 is so constructed, air stream with the short persistent period with improve pressure and less volume via blowing air line 23 output arrive this/these operating mechanisms 24。

Being first according to Fig. 5 for this makes controlling organization 12 be connected with magnet valve 4, magnet valve is connected with ejector 3 via blowing air line 5 for output pressure air, wherein, by ejector 3 can via lead to this/the blowing air line 23 of these operating mechanisms 24 produces the first blowing air stream。

In addition this controlling organization and the second magnet valve 51 connect in Figure 5, and it is connected with pressure air joint 7 and via blowing air line 51 in order to output pressure air and the second ejector 30 connect。Second ejector 30 by its air outlet slit 13 in order to export corresponding second blowing air stream via blowing air line 52 with this/these identical operating mechanisms 24 connect, thus the second blowing air stream can be supplied to identical operating mechanism 24, and first these operating mechanisms are supplied with the first blowing air stream of the first ejector 3。

By adjusting controlling organization 12 matchingly with the work tempo of paper-processing machine, during air produces, after then the first blowing air stream, export the second blowing air stream of ejector 30 and it has the pressure more relatively low than the first blowing air stream produced by ejector 3 and bigger volume。In addition the second blowing air stream can export on the longer persistent period, and thus printing material paper B can reliably be received by other conveying mechanism。

In this embodiment, for ejector 3,30 can also blowing air outlet slit side on blowing air line 23 in one pneumatic control device 22 of air outlet slit 13 arranged downstream, by means of the suction air flow that this pneumatic control device can flow out with the rhythm control of paper-processing machine。This pneumatic control device 22 can also by controlling roller structure。

Usually herein below is applicable to whole embodiments:

Magnet valve 4,10,40,50 be configured to be subject to the time to discharge or be enclosed in controlling pressure air that pressure air supply source 7 place exists is to ejector 3,30。Magnet valve is that therefore this be suitable for well in the region of dust collecter 1, because they are controllable in short and that fast successive the is followed beat cycle and therefore can follow the very short control time according to the paper-processing machine run very fast of prior art。

Magnet valve 4 is applicable to be directed on second path by pressure air or relative to ejector 3 confining pressure air and foundation connection between other blowing air line in addition。

The frame mode of magnet valve and its switch probability are usually known, therefore can easily find and use the corresponding embodiment for known task。

Whole embodiments can be one, multiple or each pressure air joint 7 distribute a pressure-regulating valve or at least one pressure-measuring device。Can so specifying this layout in the case, namely regulate can individually or jointly implement for multiple pressure air joints 7 for pressure。

In addition can at one of ejector 3,10,30 place, multiple or whole suction pneumatic fitting and/or blowing pneumatic fitting, arrange pressure-regulating valve, the suction air produced by ejector 3,10,30 and/or blowing air can be adjusted in its negative pressure or superpressure。
