Description of drawings
Set forth the preferred embodiments of the present invention in detail by accompanying drawing below.Accompanying drawing illustrates:
Fig. 1 shows the schematic side elevation of the filter tip spicing machine of a preferred embodiment of the invention;
Fig. 2 has schematically shown machine and the detailed view of ventilating system according to a first advantageous embodiment of the invention among Fig. 1 simplifiedly; And
Fig. 3 has schematically shown ventilating system according to a second, preferred embodiment of the present invention simplifiedly.
The specific embodiment
In Fig. 1,, wherein in the embodiment that specifically illustrates the filter tip spicing machine with the machine 2 of the schematically illustrated tobacco processing industry of side view.Machine 2 has housing 4, and housing comprises machine chamber 6 in the illustrated embodiment.In this machine chamber 6, arrange a plurality of cylinders, in Fig. 1, marked wherein two cylinders with Reference numeral " 7 " and " 8 " typically.
In the inner machine chamber 6 of housing 4 basically with respect to the external environment condition sealing, wherein in the wall portion of housing 4, in Fig. 1, be provided with (not being shown specifically) charging aperture with the position of Reference numeral " 10 " mark and in Fig. 1 the position with Reference numeral " 12 " mark be provided with (not being shown specifically equally) discharging opening.Cylinder has defined the process line (Prozessstra e) between charging aperture 10 and discharging opening 12, carries product, the especially bar-shaped semi-finished product of tobacco processing industry along this process line, and makes it experience some procedure of processings.
In unshowned allocation units, distribute tobacco equably; And at last (aufschauern) one-tenth tobacco net (Tabakvlies) that tobacco is broken up of same unshowned suction bar conveyer (Saugstrangf rder); And subsequently and same unshowned form and utilize packaging material to pack said tobacco net in the unit and make it form tobacco rods; Then tobacco rods is cut into tobacco rod, after this this tobacco rod enters into this filter tip spicing machine through the charging aperture 10 of the filter tip spicing machine 2 that in Fig. 1, schematically shows.There; Tobacco rod uses the filter tip section of length to fit together with twice during it is transported to discharging opening 12 from charging aperture 10 along cylinder; Coating paper coating paper (Belagpapier) in other words correspondingly twines around filter tip section; Cutting has the filter tip section in the tobacco rod of both sides tippings then, and per second cigarette with filter tip of so making be transverse to longitudinal axis Rotate 180 °, then cigarette with filter tip by means of conveyer belt 14 through discharging opening 12 outputs.
During product was carried along cylinder, before this product was passed to next cylinder, this product was temporarily attached on the cylinder.In the cylinder several have unshowned groove or recess on its shell surface at least, said groove or recess are parallel to its rotation and extend, are arranged side by side and admit each other said rod-shaped products.Make that by means of vacuum or low pressure on the shell surface of product attached to cylinder, product is come on the shell surface by suction thus.For this reason, shell surface has a plurality of suction openings, and said suction opening perhaps is directly connected on the aspirator through suction channel or is communicated with the cavity that in each cylinder, forms, and said then cavity is connected on the aspirator through suction channel.
In order in machine chamber 6, not produce the low pressure of not expecting by aforesaid aspirator at the suction run duration, must be once more with flowing to machine chamber with the corresponding basically air capacity of the air capacity of discharging.For this reason, machine 2 has air inlet transport 20, as also can seeing from Fig. 1.Air inlet transport 20 has housing 22, in this housing, arranges at least one air inlet blower fan 24.The housing 22 of this air inlet transport 20 through air inlet in other words air intake 26 be communicated with surrounding air.For this reason; In the illustrated embodiment; The housing 22 of this air inlet transport 20 is arranged on the inboard of wall portion of machine 2 housings 4 and surrounds air inlet 26, and this air inlet is formed in the wall portion of housing 4 of machine 2, as also can schematically seeing from Fig. 1.The air inlet (Zuluft) that air inlet blower fan 24 is drawn from environment through air inlet 26, and through air inlet outlet 28 air inlet is outputed in the machine chamber 6.
Preferably, air inflow can maybe can be conditioned by control, is provided with unshowned in the accompanying drawings control or adjusting device for this reason.At this, can control or regulate air inflow through the rotating speed or the power of control or adjusting air inlet blower fan 24.Alternatively or additionally, unshowned in the accompanying drawings close mechanism, lid for example can be set also, this close mechanism is opened or closed by control or adjusting device, controls or regulates so that air inlet is correspondingly entered into machine chamber 6.
Ventilate according to the detailed machine chamber of Fig. 2 below,, yet show the more detailed diagram of ventilating system although compared to Figure 1 Fig. 2 obviously more simply illustrates machine 2.Because housing in Fig. 2 in the only schematically illustrated machine 24 and machine chamber 6, and two cylinders with Reference numeral " 7 " and " 8 " only are shown represent cylinder.Yet; Compared to Figure 1; The indicative icon of the aspirator that Fig. 2 has stated before having comprised; Said aspirator has at least one aspirating air pipe 36 and at least one that is connected on the cylinder 7,8 and is connected to the air exhauster 38 on the aspirating air pipe 36 again, and this air exhauster will suck air and be discharged to the external environment condition from aspirating air pipe 36.As having stated before, on the shell surface of cylinder, form low pressure or vacuum by means of this aspirator, make thus on the shell surface of product attached to cylinder.
In order to control or regulate the suction air capacity, preferably control corresponding or adjusting device can be set, however not shown in the accompanying drawings should control or adjusting device.Can control or regulate the rotating speed or the power of air exhauster 38 by means of this control or adjusting device.Alternatively or additionally; Unshowned close mechanism also can be set, for example cover; In this close mechanism, be provided with at least one aspirating air pipe 36; Open or close this aspirating air pipe by control or adjusting device, limit (drosseln) in other words so that can correspondingly carry out throttling to the suction air capacity.
State before the same picture, the air exhauster 38 through generation adhesive force forms low pressure in machine chamber 6, and this adhesive force need be used on cylinder or along the cylinder shipping products.This low pressure can be accompanied by disadvantageous satellite phenomenon: for example the cigarette of lifting and processing as tobacco eddy current, material feeding conveyer belt (Schussf rderband) rolls back in the machine chamber through discharging opening 12 (Fig. 1) and throughput direction on the contrary.For fear of these problems; Be provided with described air inlet transport 20; Therefore this air inlet transport part that is whole ventilating system, yet and this air inlet transport in Fig. 2 equally schematically-with respect to Fig. 1-illustrate, can see the details that all are important simultaneously.Therefore; In shown embodiment; Air inlet blower fan 24 has blast pipe 40; This blast pipe 40 stops in the zone of the air inlet outlet syndeton (Zuluftauslassanschluss) 28 of air inlet transport 20 with its outlet 42, and forms portion's section of this air inlet outlet syndeton 28, as can seeing from Fig. 2.
The air inlet blower fan 24 of or conditioned in check by means of at least one can be regulated in check stress level corresponding to the corresponding demand in machine chamber 6.Yet this system is too late slow, to such an extent as to can not be without delay and the particularly quick and/or big pressure oscillation that occurs owing to different operation states of compensation in real time basically, this can cause above-cited disadvantageous satellite phenomenon again.
Not only the fluctuation in normal air capacity of draining through at least one air exhauster 38 in service is regarded as " different operation states ", and the starting process and the stopped process of machine 2 also are regarded as " different operation states " in addition.In starting process, reach capacity rotating speed and and then obtain peak power of the air exhauster 38 of being responsible on the shell surface of cylinder 7,8 producing low pressure.Big thus suction air volume flow flows, because cylinder is not also occupied (under the situation of filter tip spicing machine, product for example is the tobacco rod that has been cut) by product, but the corresponding suction hole in the shell surface of cylinder is still unlimited.With under the normal condition of production, comparing, that discharge and suction air volume flow that be directed to unshowned air core (Luftzentrale) is partly obviously bigger by said at least one air exhauster 38.Have only when all cylinders are occupied successively basically fully and and then when normal operation occurring, the obviously less suction air volume flow of part just sufficient to guarantee for confining force necessary the product on cylinder and and then guarantee operation reliably.
In stopped process, said process is carried out with opposite order.Promptly when product leaves machine chamber and cylinder and therefore soars in succession, in this case with normal in service comparing obviously bigger suction air volume flow of part can appear also, because at this moment cylinder is not occupied once more and therefore is in completely under the low pressure.
For overcome this problem and and then improve the operation of machine 2, in air inlet transport 20, be parallel to air inlet blower fan 24 and be provided with bypass 44.In according to the embodiment shown in Fig. 2, this bypass 44 is formed by the gap between the inboard in the wall portion of suction fan 24 or its housing and air inlet transport 20 housings 22 in housing 22 inside, as appreciable from Fig. 2.In the illustrated embodiment, bypass 44 be connected with suction fan 24 identical air inlets 26, and have the section 44a of portion that surrounds blast pipe 40 at outlet side, it stops with the outlet 42 adjacent outlets 46 with the blast pipe 40 of suction fan 24.Therefore, air inlet exports air outlet slit 28 in other words and is formed jointly by the outlet 42 and 46 of suction fan 24 and bypass 44.
As seeing, in air inlet transport 20, formed two air stream, first inlet air flow " P1+ " that promptly produces by at least one air inlet blower fan 24 and second inlet air flow " P2+ " through bypass 44 from Fig. 2.At this, the stress level in machine chamber 6 can be regulated through the air inlet blower fan 24 that produces first inlet air flow " P1+ " definitely, thereby the low pressure that on the shell surface of cylinder, produces and in Fig. 2, mark with " P-" is compensated.This adjusting is used for normal operation, and therefore to needs and requirement in the normal operation of production period.For the situation (as previously mentioned, especially starting, dry run and the cylinder that does not occupy belong to the variation of this running status) of the particularly stronger variation of running status generation, then bypass 44 is worked.If the variation of running status requires to increase especially especially fast to get into inlet air flow, then compensate through bypass 44, this bypass provides the air inflow of extra needs with second inlet air flow " P2+ ".At this, can almost react to the needs of the air inflow that increases without delay through bypass 44, on the contrary, even this point is because the inertia under physical condition of air inlet blower fan can not utilize 24 realizations of air inlet blower fan when the rotating speed of the best or power adjusting.So, preferred specifically with when operation changes, the air stream of the maximum that particularly in starting process or stopped process, will expect comes relative set bypass 44 relatively.
During being directed to first inlet air flow " P1+ " in the machine chamber 6 on one's own initiative by means of air inlet blower fan 24; Only through getter action (Sogwirkung) and and then in bypass 44, produce second inlet air flow " P2+ " with passive mode, wherein utilize second inlet air flow " P2+ " only to aspirate the air inlet of requirement basically.Therefore, air inlet transport 20 has formed a kind of combined type gas handling system, and it has through the active ventilation of at least one air inlet blower fan 24 with via the passive ventilation of bypass 44 through swabbing action.
That kind shown in the image pattern 2 for example; Air inlet through air inlet blower fan 24 and bypass 44 exports 42 and 46 the layout that is fit to; That can advantageously utilize first inlet air flow " P1+ " is used for strengthening second inlet air flow " P2+ " through bypass 44, we can say that at this first inlet air flow " P1+ " takes second inlet air flow " P2+ " out of.
Preferably, bypass 44 is only temporarily worked, the intake requirement that increases with the variation of satisfying as far as possible fast and without delay owing to running status.Then; Yet by before stated in the accompanying drawing unshowned control or adjusting device makes at least one air inlet blower fan high-speed cruising, bear by air inlet blower fan 24 basically once more until air inlet is supplied with: correspondingly promote first inlet air flow " P1+ " and make second inlet air flow " P2+ " correspondingly be reduced to zero through bypass 44.Therefore, in shown embodiment, correspondingly regulate at least one air inlet blower fan 24 again.
Alternatively or additionally it is also conceivable that; One or more close mechanisms especially are set in the zone of its outlet 46, for example especially cover in bypass 44 neutralizations; It is is correspondingly opened or closed by control or adjusting device, with control correspondingly or regulate the effective opening section of bypass 44 and second inlet air flow " P2+ " thus.
And the effect of making up gas handling system has been described before for the situation that inlet air flow increases, the combination gas handling system also can be used for opposite situation when following situation: because the variation of confirming of running status is to the requirement reduction of air inlet.Thus; Because counter-pressure (Gegendruck) increases when at first the power of air inlet blower fan 24 remains unchanged; Then bypass 44 is not used in additional air inlet supply; But be used for carrying out exhaust: promptly be discharged in the external environment condition through bypass 44 and air inlet 26 with the redundance of first inlet air flow " P1+ " of air inlet blower fan 24 generations and the in the opposite direction of the second schematically illustrated inlet air flow of Fig. 2 through bypass 44 through following manner; This second inlet air flow is called so-called " bearing " second inlet air flow now, and perhaps better expressing is to be called exhaust stream " P2+ " now.This only takes place so, is correspondingly regulated until air inlet blower fan 24 again.
For abating noises; Air inlet 26 can have corresponding sound insulation device 48; In the embodiment shown in Fig. 2, this sound insulation device is formed by air-locked sound insulationg board 48 basically, this sound insulationg board the internal placement of the housing 22 of air inlet transport 20 become and air inlet 26 spaced apart; And on the whole cross section of air inlet 26, extend basically, as can schematically finding out from Fig. 2.It is also conceivable that additionally or alternatively air inlet 26 also can be covered by ventilative basically sound insulationg board.
And air inlet blower fan 24 structurally forms a unit basically with bypass 44 in the embodiment that describes according to Fig. 2 before, but also it is contemplated that other structure.Therefore; Bypass can have the inlet of itself; This inlet spatially separates with the inlet that is used for air inlet blower fan 24; Wherein this inlet not only is arranged in another position on the housing 4 of machine 2, and also is arranged in another outside position of machine 2 alternatively, for example also is arranged in the adjacent room (Halle) and through connecting pipeline to be connected with bypass.Alternatively or additionally, latter event also is applicable to the inlet of air inlet blower fan 24 usefulness.Alternatively or additionally, the outlet 42 and 46 of at least one air inlet blower fan 24 and bypass 44 also can spatially be arranged in the machine 2 apart from each other.It is also conceivable that at last bypass 44 spatially was arranged with said at least one air inlet blower fan in 24 minutes.
For example; Fig. 3 with another optional embodiment show air inlet transport 20 '; It is with the difference of embodiment shown in figure 2; Bypass is not that the inner room by the housing that holds air inlet blower fan 24 forms, but by two independent, spatially form with air inlet blower fan 24 bypass channel 50a, 50b arranged apart.Two second air inlet shuntings " P2a+ " and " P2b+ " have been formed thus; Wherein the first bypass channel 50a is flow through in first air inlet shunting " P2a+ "; And the second bypass channel 50b is flow through in second air inlet shunting " P2b+ ", and forms second inlet air flow " P2+ " jointly.Like what can also indistinctly find out from Fig. 3, each bypass channel 50a, 50b have the inlet of oneself, and it is spatially arranged apart with the inlet that is used for air inlet blower fan 24.In the embodiment of Fig. 3; For the effect that makes first inlet air flow " P1+ " that is produced by air inlet blower fan 24 is advantageously used in second inlet air flow " P2+ " that enhanced flow is crossed bypass; In the illustrated embodiment; The blast pipe 40 of air inlet blower fan 24 is divided into two blast pipe branch road 14a, 14b, and they are directed into respectively among one of two bypass channel 50a, 50b, and its outlet 42a or 42b stop in the zone of the outlet 52a of bypass channel 50a, 50b or 52b.
