Abstract

In the installation proposed, an air duct (16) runs parallel to and below the linear trackway (8) of a travelling cleaner (10), and the cleaner trackway and air duct run above a row (6) of looms (4). Fitted above each loom on the underside of the air duct (16) is a downwards-facing air displacement flow outlet (20) which is supplied with suitably conditioned air from the air duct. Fitted in the floor (24) below each loom is an air outlet (28) which is linked to an air-extraction duct (32). The air extracted by the air-extraction duct (32) is conditioned in an air-conditioning installation and then fed back into the air duct (16). The fact that the air duct is mounted parallel to the travelling-cleaner trackway permits the installation to be designed so that it is simple and less costly.

Description

Die Erfindung betrifft eine Anlage nach dem Oberbegriff von Anspruch 1.The invention relates to a system according to the preamble of claim 1.

An Textilmaschinen ist es schon seit langem üblich, Wanderreiniger einzusetzen, mit welchen durch Blas- und/oder Saugluftströme die Verarbeitungsstellen derselben bestrichen werden, um freigesetzten Flug und Staub vom verarbeiteten Faser-, bzw. Fadenmaterial fernzuhalten, bzw. dessen Ablagerung an der Maschine zu reduzieren.It has long been common on textile machines to use traveling cleaners, with which blowing and / or suction air streams are applied to the processing points of the same, in order to keep released flight and dust away from the processed fiber or thread material, or to prevent it from being deposited on the machine to reduce.

Dabei sind auch schon Vorrichtungen bekannt geworden, bei welchen die Fahrbahn der Wanderreiniger über eine Mehrzahl von nacheinander bestrichenen Textilmaschinen führt. Die Fahrbahn ist dabei meist über Ständer an den Maschinen selbst oder am Boden abgestützt. Derartige Vorrichtungen sind z.B. aus den Druckschriften GB-A- 1 018 718 und DE-B- 1 205 920 bekannt.Devices have also become known in which the travel path of the traveling cleaners runs over a plurality of textile machines which are swept one after the other. The roadway is usually supported by stands on the machines themselves or on the ground. Such devices are e.g. known from GB-A-1 018 718 and DE-B-1 205 920.

Bei der Untersuchung von Garnen und Geweben hat es sich gezeigt, dass diese einen erstaunlich hohen Gehalt an Flug und Staub aufweisen. In den textilen Verarbeitungsprozessen selbst treten relativ häufig Fadenbrüche auf, die u.a. auf den hohen Gehalt von Verunreinigungen in der Umgebungsluft, bzw. auf Ansammlungen von Verunreinigungen an Verarbeitungsstellen zurückzuführen sind.When examining yarns and fabrics, it has been shown that they have an astonishingly high level of flight and dust. Thread breaks occur relatively often in the textile processing processes themselves, which among other things are due to the high content of impurities in the ambient air or to the accumulation of impurities at processing points.

Aufgabe der Erfindung ist daher die Schaffung einer Anlage, mit welcher bei vergleichsweise niedrigen Investitionskosten die Verunreinigungen jedenfalls in den kritischen Verarbeitungsbereichen deutlich herabgesetzt werden können.The object of the invention is therefore to create a system with which the contaminants can in any case be significantly reduced in the critical processing areas with comparatively low investment costs.

Erfindungsgemäss wird diese Aufgabe mit den Merkmalen des Kennzeichens von Anspruch 1 gelöst.According to the invention, this object is achieved with the features of the characterizing part of claim 1.

Unter einem Kolbenströmungs-Auslass wird im vorliegenden Zusammenhang ein Auslass verstanden, der eine kolbenartige Verdrängungsströmung mit annähernd einheitlicher Verteilung und annähernd einheitlicher Geschwindigkeit erzeugt. Mit geeigneten Austrittsgeschwindigkeiten etwa zwischen 0,3 und 1,2 m/sec entsteht dann eine zumindest turbulenzarme Strömung.In the present context, a piston flow outlet is understood to mean an outlet which generates a piston-like displacement flow with an approximately uniform distribution and approximately uniform speed. With suitable exit speeds of between 0.3 and 1.2 m / sec, an at least low-turbulence flow is created.

Durch das Zusammenwirken einer über den Verarbeitungszonen aller Maschinen dauernd fliessenden gezielten Kolbenströmung mit einem in der Nachbarschaft der Verarbeitungszonen derselben periodisch wirksamen Wanderreiniger wird eine deutliche Herabsetzung der Zahl der Fadenbrüche sowie eine Verbesserung der Qualität des verarbeiteten textilen Materiales erreicht. Es gelingt dies durch die vermittels der Verdrängungsströmung praktisch staubfrei gehaltene Arbeitszone, wie auch die durch den Wanderreiniger vermiedene Gefahr von Ansammlungen von Verunreinigungen an für die Verarbeitung kritischen Maschinenteilen. Durch den paralellen Verlauf des Luftkanales mit jenem der Fahrbahn des Wanderreinigers ergeben sich gerade Wege sowohl für die Strömung, wie auch für die Bewegung des Wanderreinigers, bzw. lassen sich Kreuzungs-Probleme vermeiden.Through the interaction of a targeted piston flow that flows continuously over the processing zones of all machines with a cleaning cleaner that is active periodically in the vicinity of the processing zones of the same, a significant reduction in the number of thread breaks and an improvement in the quality of the processed textile material is achieved. This is achieved thanks to the working zone, which is kept practically dust-free by means of the displacement flow, as well as the risk of accumulation of contaminants on machine parts critical for processing, which is avoided by the traveling cleaner. Due to the parallel course of the air duct with that of the traveling cleaner's lane, there are straight paths for both the current and the movement of the traveling cleaner, or problems with intersections can be avoided.

Weitere Vorteile der erfindungsgemässen Anlage und besonders zweckmässige Ausgestaltungen derselben sind weiter unten beschrieben.Further advantages of the system according to the invention and particularly expedient refinements thereof are described below.

Wie aus den Fig. 1 und 2 ersichtlich ist, sind in einem Websaal 2 Webmaschinen 4 in mehreren paralellen Reihen 6 angeordnet. Über je zwei unmittelbar benachbarten Reihen 6 verläuft eine in sich geschlossene Fahrbahn 8 eines an sich bekannten Wanderreinigers 10. Die Fahrbahn 8 weist neben geraden, zu den Reihen 6 paralellen Teilen 12, die letzteren miteinander verbindende bogenförmige Teile 14 auf.As can be seen from FIGS. 1 and 2, 2 weaving machines 4 are arranged in several parallel rows 6 in a weaving room. A self-contained roadway 8 of a known hiking cleaner 10 runs over each two adjacent rows 6. The roadway 8 has, in addition to straight parts 12 parallel to the lines 6, the latter connecting arcuate parts 14.

Parallel zu den geraden Teilen 12 der Fahrbahn 8 erstrecken sich oberhalb der Reihen 6 von Webmaschinen 4 Luftkanäle 16. An den Unterseiten 18 der Luftkanäle 16 ist über jeder Webmaschine 4 ein nach abwärts gerichteter Kolbenströmungs-Auslass 20 vorgesehen. Geeignete solche Auslässe sind als Lokalauslässe in der schweizerischen Patentanmeldung 02 815/91-3 vom 23.09.1991 sowohl bezüglich konstruktiver Ausgestaltung als auch bezüglich räumlicher Anordnung, bzw. Lage über einer Webmaschine beschrieben. Allerdings sind auch andere Ausgestaltungen solcher Auslässe möglich.4 air channels 16 extend parallel to the straight parts 12 of the roadway 8 above the rows 6 of weaving machines 16. A downward-directed piston flow outlet 20 is provided on the undersides 18 of the air channels 16 above each weaving machine 4. Suitable such outlets are described as local outlets in Swiss patent application 02 815 / 91-3 dated September 23, 1991, both with regard to the structural design and with regard to spatial arrangement or location above a weaving machine. However, other configurations of such outlets are also possible.

Zwei Verteilkanäle 22, die unter dem Boden 24 des Webmaschinensaales 2 voneinander distanziert, jedoch paralell zueinander verlaufen, sind über Steigrohre 26 mit jedem der Luftkanäle 16 verbunden. Die beiden Verteilkanäle 22 sind an eine gemeinsame, nicht dargestellte Klimazentrale angeschlossen. Über die Verteilkanäle 22, die Steigrohre 26 und die Luftkanäle 16 werden die Auslässe 20 mit Luft von in der Regel hohem Feuchtegehalt versorgt. Da jeder der Luftkanäle 16 an zwei distanzierten Stellen mit Luft aus den Verteilkanälen 22 angespiesen wird, ist mit relativ kleinem Kanalquerschnitt eine gleichmässige Versorgung aller Kolbenströmungs-Auslässe 20 möglich.Two distribution channels 22, which are spaced apart from one another under the floor 24 of the weaving machine hall 2, but run parallel to one another, are connected to each of the riser pipes 26 Air channels 16 connected. The two distribution channels 22 are connected to a common climate control center, not shown. The outlets 20 are supplied with air of generally high moisture content via the distribution channels 22, the risers 26 and the air channels 16. Since each of the air ducts 16 is supplied with air from the distribution ducts 22 at two distant locations, a uniform supply of all piston flow outlets 20 is possible with a relatively small duct cross section.

Der Boden 24 weist unterhalb jeder Webmaschine 4 mindestens eine Abluftöffnung 28 auf. Jeweils mehrere Abluftöffnungen 28 sind über Sammlerleitungen 30 und Absaugkanäle 32 mit der Klimazentrale verbunden. Vermittels der Abluftöffnungen 28 wird im wesentlichen die von den Kolbenströmungs-Auslässen 20 stammende Luft aus dem Webmaschinensaal 2 abgeführt, nachdem diese ihre Funktion erfüllt hat. Im Falle mehrerer Abluftöffnungen je Maschine ist es zweckmässig, mindestens je eine für das Abführen des vom Wanderreiniger herangetragenen Fluges und Staub vorzusehen.The bottom 24 has at least one exhaust air opening 28 below each weaving machine 4. Several exhaust air openings 28 are connected to the air conditioning center via collector lines 30 and suction channels 32. By means of the exhaust air openings 28, essentially the air originating from the piston flow outlets 20 is removed from the weaving machine room 2 after it has fulfilled its function. In the case of several exhaust air openings per machine, it is advisable to provide at least one for the removal of the flight and dust carried by the traveling cleaner.

Es bleibt nachzutragen, dass die Luftkanäle 16 und die geraden Fahrbahn-Teile 12, allgemein ausgedrückt, vorzugsweise gemeinsam abgestützt sind. Im Fall des hier beschriebenen Ausführungsbeispieles erfolgt die Abstützung am Boden 24 über eine Mehrzahl von zwischen den Webmaschinen 4 paarweise verteilt angeordneten Stützsäulen 34.It remains to be added that the air ducts 16 and the straight roadway parts 12, generally speaking, are preferably supported together. In the case of the exemplary embodiment described here, the support on the floor 24 takes place via a plurality of support columns 34 arranged in pairs between the weaving machines 4.

Insbesondere wenn die Maschinenreihen kurz sind, d.h. eine vergleichsweise kleine Zahl je Reihe angeordnet sind, kann es ebenfalls zweckmässig sein, die Abstützung der Fahrbahn und des Luftkanals an der Saaldecke vorzusehen und die Anspeisung des Luftkanals von den Enden der Reihen her vorzunehmen. In einem solchen Fall ist für den Wanderreiniger eine auch allgemein in Betracht kommende Hin-und Herbewegung auf einer geraden Bahn vorzusehen.In particular if the machine rows are short, ie a comparatively small number is arranged per row, it may also be expedient to provide support for the carriageway and the air duct on the ceiling of the hall and to feed the air duct from the ends of the rows. In such a case is for the hiking cleaner to provide a reciprocating movement on a straight path, which is also generally considered.

Aus Fig. 3 ist ersichtlich, dass der Kolbenströmungs-Auslass 20 an einem am Luftkanal 16 angebrachten Auslasskasten 84 vorgesehen ist. Weiterhin ergibt sich, dass der Wanderreiniger 10 mehrere mit Blasdüsen 42 ausgestatte Rohrarme 40 aufweist. Ein Ventilator 44 versorgt die Blasdüsen 42 über die an diesen angeschlossenen Rohrarme 40 mit angesaugter Raumluft. Die Blasdüsen 42 sind so ausgerichtet, dass diese beim Durchgang des Wanderreinigers beidseits der aus dem Kolbenströmungs-Auslass 20 austretenden, bei 46 angedeuteten Verdrängungsströmung Teile der Webmaschine 4 mit entsprechenden Luftströmen bestreichen.It can be seen from FIG. 3 that the piston flow outlet 20 is provided on an outlet box 84 attached to the air duct 16. Furthermore, it follows that the traveling cleaner 10 has a plurality of tubular arms 40 equipped with blowing nozzles 42. A fan 44 supplies the blowing nozzles 42 with sucked-in room air via the pipe arms 40 connected to them. The blowing nozzles 42 are aligned such that they pass parts of the weaving machine 4 with corresponding air streams as the traveling cleaner passes through on both sides of the displacement flow, indicated at 46, emerging from the piston flow outlet 20.

Bei 48 sind zwei durch den Luftkanal 16 selbst gebildete Schienen dargestellt, die den geraden Teil 12 der Fahrbahn 8 des Wanderreinigers 10 definieren. Mit 52 sind ein Fahrwerk für den Wanderreiniger 10 bildende Laufrollen bezeichnet, von denen mindesten eine mit einem den Fahrantrieb bildenden, nicht dargestellten Elektromotor in Antriebsverbindung steht. An einer der Seitenwände des Luftkanals 16 ist eine Stromschiene 54 befestigt. Ein am Wanderreiniger 10 befestigter, nicht dargestellter Schleifersatz steht mit der Stromschiene 54 in dauerndem Kontakt. Der Schleifersatz ist seinerseits mit dem den Fahrantrieb bildenden Elektromotor sowie mit einem Elektromotor 56 für den Antrieb des Ventilators 44 elektrisch leitend in Verbindung.At 48, two rails formed by the air duct 16 themselves are shown, which define the straight part 12 of the roadway 8 of the traveling cleaner 10. With 52 a chassis for the traveling cleaner 10 forming rollers are designated, at least one of which is in drive connection with an electric motor, not shown, which forms the travel drive. A busbar 54 is attached to one of the side walls of the air duct 16. A grinding set, not shown, attached to the traveling cleaner 10 is in constant contact with the busbar 54. The grinding set is in turn electrically conductively connected to the electric motor forming the travel drive and to an electric motor 56 for driving the fan 44.

Der Luftkanal 16 dient überdies als Träger für Beleuchtungskörper 58, für eine mit allen Webmaschinen der gleichen Reihe 6 verbundenen Druckluftleitung 60 sowie für einen Kabelkanal 62 für die Stromversorgung der Webmaschinen 4 derselben.The air duct 16 also serves as a support for lighting fixtures 58, for a compressed air line 60 connected to all weaving machines in the same row 6 and for a cable duct 62 for the power supply of the weaving machines 4 of the same.

Das Ausführungsbeispiel nach Fig. 4 unterscheidet sich von demjenigen nach Fig. 1 - 3 hauptsächlich dadurch, dass die Höhenlage der nachfolgend beschriebenen Anlageteile voneinander unabhängig ausgelegt werden kann. Spezifisch ist der hier mit 116 bezeichnete Luftkanal von der Fahrbahn 108 distanziert und unterhalb derselben verlaufend angeordnet. Anstelle der Stützsäulen 34 können hier jeweils eine Säule für den Luftkanal 116 und eine weitere für den die Fahrbahn 108 vorgesehen sein. Jedoch ist es meist zweckmässig, die Abstützung beider dieser Elemente durch jeweils eine gemeinsame Stütze 134 vorzunehmen.The exemplary embodiment according to FIG. 4 differs from that according to FIGS. 1-3 mainly in that the height of the system parts described below can be designed independently of one another. Specifically, the air duct, designated 116 here, is distanced from the roadway 108 and arranged below it. Instead of the support columns 34, one column can be provided for the air duct 116 and another for the roadway 108. However, it is usually expedient to support both of these elements by a common support 134 in each case.

Weiter ist der Luftkanal 116 über Verbindungsstutzen 170 mit den Kolbenströmungs-Auslässen 120 verbunden. Damit lassen sich diese Auslässe in einem geeigneten Wirkabstand von der Webmaschine anordnen, ohne dabei die Höhenlage des Luftkanals 116 vorzubestimmen. Darüberhinaus lassen entsprechend geformte Verbindungsstutzen auch eine seitliche Versetzung des Luftkanals 116 bezüglich der Auslässe zu, deren eigene seitliche Lage durch die zwingende Ausrichtung der Verdrängungsströmung vorbestimmt ist.Furthermore, the air duct 116 is connected to the piston flow outlets 120 via connecting pieces 170. These outlets can thus be arranged at a suitable effective distance from the weaving machine without pre-determining the height of the air duct 116. In addition, appropriately shaped connecting pieces also allow lateral displacement of the air duct 116 with respect to the outlets, the lateral position of which is predetermined by the mandatory orientation of the displacement flow.

Ein weiterer Unterschied zum zuvor beschriebenen Ausführungsbeispiel besteht bei demjenigen nach Fig. 4 darin, dass der Wanderreiniger 110 sowohl als Blas- als auch als Saugreiniger ausgebildet ist. Hierzu sind an die Saugseite des Ventilators 144 Saugarme 172 angeschlossen, die in Bodennähe angeordnete Saugorgane 174 tragen. Für angesaugte und aus dem Luftstrom abgeschiedene Verunreinigungen sind dem Ventilator 144 in bekannter Weise Sammelkästen 176 zugeordnet. Die Blasdüsen 142 sind über rüsselartige Organe 178 mit dem Ventilator 144 verbunden.Another difference from the previously described exemplary embodiment in that according to FIG. 4 is that the traveling cleaner 110 is designed both as a blow cleaner and as a suction cleaner. For this purpose, suction arms 172 are connected to the suction side of the fan 144 and carry suction members 174 arranged near the floor. For contaminants drawn in and separated from the air flow, collecting boxes 176 are assigned to the fan 144 in a known manner. The blowing nozzles 142 are connected to the fan 144 via proboscis organs 178.

Für den Betrieb der Anlage kann es zweckmässig sein, wenn sich Kolbenströmungs-Auslässe eine individuelle Anpassung des Volumens ermöglichen, was mit dem in Fig. 4 angedeuteten Drossel-Organ 192 im Verbidungsstutzen 170 möglich ist. Das Drossel-Organ 192 kann auch geeignet sein, den Zustrom der Luft zum Auslass bei abgestellter Maschine gänzlich zu unterbrechen. Sowohl das Anpassen, wie auch das Unterbrechen kann über ein mit 194 bezeichnetes Betätigungs-, bzw. Stellorgan erfolgen, dass gegebenfalls Teil einer die Anlage umfassenden Prozessteuerung ist.For the operation of the system, it can be expedient if piston flow outlets allow an individual adjustment of the volume, which is possible with the throttle element 192 indicated in FIG. 4 in the connecting piece 170. The throttle element 192 can also be suitable for completely interrupting the inflow of air to the outlet when the machine is switched off. Both the adaptation and the interruption can take place via an actuating or actuating element, designated 194, which may be part of a process control comprising the system.

Bei der Webmaschine 104 nach Fig. 4 handelt es sich um eine Luftdüsen-Webmaschine, jedoch ist die Verdrängungsströmung 146 auch hier gegen die Webkette 179, das Hinterfach 180 teilweise unmittelbar überdeckend, ausgerichtet.The weaving machine 104 according to FIG. 4 is an air-jet weaving machine, but here too the displacement flow 146 is aligned against the warp chain 179, partially directly overlapping the rear compartment 180.

In den Fig. 5 und 6 ist eine Ausgestaltungsvariante eines Luftkanales dargestellt. Der einen rechteckigen Querschnitt aufweisende Luftkanal 216 weist horizontale Schmalseiten 281 und vertikale Breitseiten 282 auf. An der in der Zeichnung linksseitigen Breitseite 282 ist ein Auslasskasten 284 angebracht. Dieser weist einen nach abwärts gerichteten Kolbenströmungs-Auslass 220 auf und ist mit dem Innenraum 286 des Luftkanals 216 über eine von Ablenkelementen 288 besetzte schlitzförmige Durchtrittsöffnung 290 verbunden.5 and 6, an embodiment variant of an air duct is shown. The air duct 216, which has a rectangular cross section, has horizontal narrow sides 281 and vertical broad sides 282. An outlet box 284 is attached to the broad side 282 on the left in the drawing. This has a downward-directed piston flow outlet 220 and is connected to the interior 286 of the air duct 216 via a slot-shaped passage opening 290 occupied by deflection elements 288.

An der oberen Schmalseite 281 des Luftkanals 216 sind wiederum die Schienen 248 der Fahrbahn 208 angeformt, auf welcher sich der bei 210 angedeutete Wanderreiniger bewegt. An dem auch hier einen Träger bildenden Luftkanal 216 sind Beleuchtungskörper 258 an der unteren Schmalseite 281 befestigt. Der Luftkanal 216 ist seinerseits an Stützen 234 gehalten.On the upper narrow side 281 of the air duct 216, the rails 248 of the carriageway 208 are in turn formed, on which the traveling cleaner indicated at 210 moves. Lighting elements 258 are fastened to the lower narrow side 281 on the air channel 216 which also forms a carrier here. The air duct 216 is in turn held on supports 234.

Selbstverständlich lassen sich die die Fahrbahn des Wanderreinigers bildenden Schienen auch als vom Luftkanal selbständige Teile ausbilden, die durch entsprechende Verbindung mit diesem Kanal versteift sind.Of course, the rails forming the roadway of the traveling cleaner can also be designed as parts independent of the air duct, which are stiffened by a corresponding connection to this duct.

Es ist meist zweckmässig, die Anlage für die Herstellung zumindest des Maschinenklimas zu verwenden, das für den jeweiligen speziellen Verarbeitungsprozess bzw. das verarbeitete Material bezüglich Feuchte und Temperatur geeignet ist. Allerdings kann diese Funktion auch einer getrennten Klimaanlage überlassen werden. Anderseits lässt sich, jedenfalls in vielen Fällen, auf jegliche andere Klimatisierung im Saal verzichten, wenn die erfindungsgemässe Anlage entsprechend ausgelegt ist. Ein Teil der über die Kolbenströmungs-Auslässe ausgebrachten Klima-Luft ist in diesem Fall für die unmittelbare Beinflussung des Raumklimas vorzusehen. Obwohl die Erfordernisse eines sowohl für die Bedienungspersonen wie auch für den Verarbeitungsprozess geeigneten Klimas beachtet werden, lassen sich hiermit wesentliche Einsparungen bezüglich ingesamt aufgewendeter Energie erzielen.It is usually expedient to use the system for the production of at least the machine climate that is suitable for the respective special processing process or the processed material with regard to humidity and temperature. However, this function can also be left to a separate air conditioning system. On the other hand, in any case, in any case, any other air conditioning in the hall can be dispensed with if the system according to the invention is designed accordingly. In this case, part of the climatic air discharged via the piston flow outlets is to be provided for the direct influencing of the indoor climate. Although the requirements of a climate that is suitable for both the operator and the processing process are observed, significant savings can be achieved in terms of the total energy used.

Die erfindungsgemässe Anlage lässt sich unter Erzielung vergleichbarer Ergebnisse bei andern Textilmaschinen verwenden, bei welchen durch den Verarbeitungsprozess Flug und Staub freigesetzt werden. Es gilt dies insbesondere für Maschinen, die dem Spinnprozess dienen.The system according to the invention can be used to achieve comparable results in other textile machines in which the processing process releases air and dust. This applies in particular to machines that serve the spinning process.
