Description

Die Erfindung bezieht sich auf eine Anlage zum Fixieren von Farbstoffen mittels Dampf, in der eine Dämpfer-Waschmaschinen-Kombination zur Anwendung kommt, wie sie beispielsweise in der DE 20 02 144 A1 beschrieben ist. Der Flor der Teppichbahn ist auf den oberen Umlenkwalzen nach außen gerichtet, so daß in der heißen Sattdampfatmosphäre kein starker Druck auf die erweichten Fasern ausgeübt wird. Nach dem Dampffixieren ist die Warenbahn in einer Waschmaschine von den auswaschbaren Farbrestbestandteilen zu reinigen. Es ist dazu in der Offenlegungsschritt eine Siebtrommelwaschmaschine offenbart, der ein Absaugschlitz zum Entfernen des Schmutzwassers auf der Sichtseite der Warenbahn nachgeordnet ist.The invention relates to a system for fixing dyes by means of steam, in which a damper-washing machine combination is used, as described for example in DE 20 02 144 A1. The pile of the carpet web is directed outwards on the upper deflection rollers, so that no strong pressure is exerted on the softened fibers in the hot saturated steam atmosphere. After the steam has been fixed, the washable paint residues are to be cleaned in a washing machine. For this purpose, a sieve drum washing machine is disclosed in the disclosure step, followed by a suction slot for removing the dirty water on the visible side of the web.

In der gleichen Offenlegungsschrift ist weiterhin noch eine Absaugvorrichtung unmittelbar im Anschluß an den Auslaufschlitz des Dämpfers dargestellt, die auf der Florseite der Warenbahn angeordnet für das Ausrichten der Florfasern im noch weichen Zustand der Fasern sorgen soll. Die gleiche Aufgabe hat das Wasserschloß gemäß dieser Offenlegungsschrift am Auslauf des Dämpfers, in dem der Flor von der heißen Dampfatmosphäre langsam bis zum Auslauf des Wasserschlosses abkühlen soll. Selbstverständlich erfolgt auch dabei ein gewisses Vorwaschen. In diesem Zusammenhang ist auf die DE 20 02 971 A1 zu verweisen, bei der das am Auslaufschlitz des Dämpfers angeordnete Wasserschloß im Gegenstrom mit der schmutzigen Waschflüssigkeit der nachgeordneten Waschmaschine versorgt wird, um dort ein gewisses Vorwaschen zu bewirken.In the same publication, a suction device is also shown immediately following the outlet slot of the damper, which is arranged on the pile side of the web to ensure the alignment of the pile fibers while the fibers are still soft. The water castle has the same task according to this published specification at the outlet of the steamer, in which the pile is to cool slowly from the hot steam atmosphere to the outlet of the water castle. Of course, there is also a certain amount of prewashing. In this connection, reference is made to DE 20 02 971 A1, in which the water lock arranged at the outlet slot of the damper is supplied in countercurrent with the dirty washing liquid of the washing machine arranged downstream in order to effect a certain prewash there.

Waschmaschinen der in den beiden Offenlegungschriften dargestellten Art werden aus Kostengründen in den neueren Anlagen durch Waschmaschinen nach der DE-GM 86 31 105 ersetzt. Es konnte in der Praxis festgestellt werden, daß das bloße Aufspritzen von Waschflüssigkeit auf die Rückseite der Warenbahn und das sofort sich anschließende Absaugen dieser Waschflüssigkeit von der Florseite der Warenbahn einen guten Wascheffekt erzielt. Selbstverständlich kann die Warenbahn auch getaucht werden, um den Flor mit mehreren 100 % Wasser zu tränken.Washing machines of the type shown in the two published documents are replaced by washing machines according to DE-GM 86 31 105 in the newer systems for cost reasons. It was found in practice that the mere spraying of washing liquid onto the back of the web and the immediately subsequent suction of this washing liquid from the pile side of the web achieves a good washing effect. Of course, the web can also be submerged to soak the pile with several 100% water.

Ausgehend von der Dämpfer-Waschanlage anfangs genannter Art liegt der Erfindung die Aufgabe zugrunde, eine solche Anlage zu entwickeln, mit der ein besserer Wascheffekt erzielt werden kann. Es hat sich in der Praxis gezeigt, daß die üblichen Waschmaschinen zum Auswaschen der Farbrestbestandteile insbesondere auch der Applikationen zur Erzeugung eines besonderen Farbeffektes aus den Teppichen nicht ausreicht. Eine Verdopplung der Waschmaschine ist jedoch zu teuer und ein Weglassen der Applikationen ist aus Gründen der Farbrezepturen nicht möglich. Es besteht die Idee, die Vornetz-Einrichtung gemäß der DE 20 02 971 A1 so auszugestalten, daß damit ein eindeutiger Wascheffekt erzielt werden kann. Es hat sich herausgestellt, daß ein Wasserschloß der offenbarten Art zur Verhinderung des Dampfaustritts an einem Sattdampfdämpfer nicht notwendig ist. Es kann auf andere Art und Weise verhindert werden, daß ein Dampfverlust vermieden wird. Das reine Netzen der Warenbahn ist jedoch ohne Bedeutung für einen erwünschten Wascheffekt, so daß hier nach einer möglichen Besserung gesucht werden soll.Starting from the damper washing system of the type mentioned initially, the object of the invention is to develop such a system with which a better washing effect can be achieved. It has been shown in practice that the customary washing machines for washing out the residual color components, in particular also the applications, are not sufficient for producing a special color effect from the carpets. However, doubling the washing machine is too expensive and omitting the applications is not possible due to the color recipes. The idea is to design the pre-network device according to DE 20 02 971 A1 in such a way that a clear washing effect can be achieved with it. It has been found that a water lock of the type disclosed is not necessary to prevent steam escaping from a saturated steam damper. There are other ways of preventing steam loss. However, the pure wetting of the web is of no importance for a desired washing effect, so that a possible improvement should be sought here.

Im Gegensatz zur bisherigen Ansicht, die Warenbahn im Wasserschloß im Auslaufschlitz des Dämpfers abkühlen zum müssen, ist der Erfinder auf die Idee gekommen, die dem Teppich beim Auslaufen aus dem Dämpfer noch innewohnende Energie beim Waschvorgang zu nutzen. Die Erfindung sieht deshalb vor, zwischen der bekannten Waschvorrichtung und dem Dämpfer eine Vor-Waschvorrichtung mit zumindest einer Warenbahnnetz- und -absaugvorrichtung vorzusehen und diese ohne wesentlichen Abstand zur Auslaufwandung des Dämpfers unmittelbar an dem Dämpfer anzuordnen und zumindest von einer Absaughaube abzudecken. Die Idee ist also, den heißen aus dem Dämpfer auslaufenden Teppich in dieser Wärme gleich dem ersten intensiven Waschvorgang zu unterziehen. Mit Hilfe von notwendigen Umlenkwalzen wird die Warenbahn so geführt, daß die Teppichbahn ohne wesentliche Abkühlung, aber außerhalb des Dämpfers z. B. auf der Rückseite der Warenbahn mit einer Waschflüssigkeit versehen und gleich anschließend von der Sichtseite abgesaugt werden kann. Selbstverständlich ist auch hier ein Tauchen der Warenbahn möglich.Contrary to the previous view of having to cool the web in the water lock in the outlet slot of the damper, the inventor came up with the idea of using the energy inherent in the carpet when it comes out of the damper during the washing process. The invention therefore provides to provide a pre-washing device with at least one web mesh and suction device between the known washing device and the damper and to arrange this directly on the damper without a substantial distance from the outlet wall of the damper and at least to cover it with a suction hood. So the idea is to subject the hot carpet running out of the steamer to the first intensive washing process in this warmth. With the help of necessary deflection rollers, the web is guided so that the carpet web without significant cooling, but outside the damper z. B. provided on the back of the web with a washing liquid and immediately sucked off from the visible side. Of course diving of the web is also possible here.

Es ist besonders vorteilhaft, wenn die Warenbahn auf der Florseite vor dem Aufspritzen der Waschflüssigkeit bzw. dem Absaugbalken mit einer Abstreifrakel beaufschlagt wird, um so besondere Applikationen z. B. den Gum-Auftrag abzurakeln, und dadurch ein schnelleres und intensiveres Waschen in den nachfolgenden Waschenrichtungen zu ermöglichen.It is particularly advantageous if the web on the pile side is subjected to a doctor blade before the washing liquid or the suction bar is sprayed on, in order to achieve special applications such. B. scraping off the gum application, thereby enabling faster and more intensive washing in the subsequent washing directions.

Diese zusätzliche Vor-Waschvorrichtung ist als Teil des Dämpfers anzusehen. Es ist besonders vorteilhaft, wenn die Dampfabsaughaube oberhalb der Vor-Wascheinrichtung diese in voller Höhe umgibt, so daß innerhalb dieser Vor-Wascheinrichtung eine sehr heiße Dampfatmosphäre herrscht, um insbesondere die Applikationen mittels der Abstreifrakel von der Warenbahn entfernen zu können. Im oberen Bereich der Dampfabsaughaube ist selbstverständlich ein Absaugstutzen für dieses heiße Dampf-Luft-Gemisch angeordnet, bei der jedoch der Absaugventilator nur so stark aktiv ist, daß kein wesentlicher Luftzug von unten erzeugt wird. Jedenfalls soll hier in dieser Vor-Wascheinrichtung kein wesentliches Abkühlen der Warenbahn durch diesen Luftzug bewirkt werden.This additional pre-washing device is part of the damper. It is particularly advantageous if the steam extraction hood above the pre-washing device surrounds it in full, so that within this pre-washing device there is a very hot steam atmosphere, in particular to be able to remove the applications from the web using the doctor blade. In the upper area of the steam extraction hood there is of course a suction nozzle for this hot steam-air mixture, but in which the suction fan is only so strongly active that no significant air draft is generated from below. In any case, there should be no significant cooling of the material web by this air draft in this pre-washing device.

Der Laufschlaufendämpfer ist mit 1 bezeichnet und weist an seiner Decke angetrieben umlaufende Warenbahnumlenkrollen 2 zum Tragen und Transportieren der Teppichbahn 3 auf. Der Laufschlaufendämpfer ist von einem Gehäuse 4 umgeben, das auch nur aus einer Dämpferhaube bestehen kann. An der stirnseitigen Dämpfer-Auslaufwandung 5 ist unterhalb der unteren Enden der Laufschlaufen 3' der Dämpfer-Auslaufschlitz 6 angeordnet. Auf diese Weise strömt nur wenig zur Sicherheit eines luftfreien Dämpfers erzeugter Überschußdampf aus dem Schlitz 6 aus. Aus Sicherheitsgründen ist oberhalb dieses Dämpfer-Auslaufschlitzes 6 an der Außenseite dieser Auslaufwandung 5 ein Dampfabsaugschacht 7 angeordnet. Im Falle der Vorrichtung nach Fig. 1 beginnt dieser Dampfabsaugschacht erst weiter oberhalb in der Absaughaube 20, da nicht in jedem Fall der Überschußdampf gleich oberhalb des Auslaufschlitzes 6 abgesaugt werden muß.The loop damper is denoted by 1 and has driven web deflection rollers 2 driven on its ceiling for carrying and transporting the carpet web 3. The loop damper is surrounded by a housing 4, which can also consist of only one damper cover. On the front damper outlet wall 5, the damper outlet slot 6 is arranged below the lower ends of the running loops 3 '. In this way, little excess steam generated for the safety of an air-free damper flows out of the slot 6. For safety reasons, a steam suction shaft 7 is arranged above this damper outlet slot 6 on the outside of this outlet wall 5. In the case of the device according to FIG. 1, this steam suction shaft only begins further above in the suction hood 20, since the excess steam does not always have to be suctioned off directly above the outlet slot 6.

Nach dem Laufschlaufendämpfer 1 ist in Warentransportrichtung der Kontinue-Anlage eine Waschmaschine 8 angeordnet, die im Falle der Fig. 1 und 2 aus einem Waschturm besteht, in dem die Warenbahn mehrfach von Waschflüssigkeit bespritzt und gleich anschließend von der Warenbahnsichtseite abgesaugt wird. Jede Waschstufe besteht jeweils aus zwei in Transportrichtung der Warenbahn nebeneinander angeordneten Umlenkwalzen 9 und 10, zwischen denen der der Florseite zugeordnete Absaugbalken 11, von unten her wirksam, angeordnet ist. Es ist vorteilhaft die Umlenkwalzen 9, 10 etwa horizontal nebeneinander anzuordnen, damit der Absaugbalken 11 lotrecht von unten saugen kann. Sollte die Warenbahn 3 getaucht werden, so ist eine zusätzliche Umlenkwalze 12 innerhalb eines Tauchbades 13 vorzusehen. Das Tauchbad 13 kann aber auch als Wanne nur zum Auffangen der überflüssigen Flüssigkeit vorgesehen sein, die auf die Warenbahn von unten mittels der Sprühvorrichtung 14 in den Schlitz zum Absaugbalken 11 und von oben mittels der Sprühvorrichtung 15 in den Schlitz zur Umlenkwalze 12 gespritzt wird.After the loop damper 1, a washing machine 8 is arranged in the goods transport direction of the continuous system, which in the case of FIGS. 1 and 2 consists of a washing tower in which the web is sprayed with washing liquid several times and then immediately sucked off from the web side. Each washing stage consists of two deflection rollers 9 and 10 arranged side by side in the transport direction of the web, between which the suction bar 11 assigned to the pile side is arranged, effective from below. It is advantageous to arrange the deflecting rollers 9, 10 approximately horizontally next to one another so that the suction bar 11 can suck vertically from below. If the web 3 is immersed, an additional deflecting roller 12 is to be provided within an immersion bath 13. The immersion bath 13 can also be provided as a trough only for collecting the superfluous liquid which is sprayed onto the material web from below by means of the spray device 14 into the slot for the suction bar 11 and from above by means of the spray device 15 into the slot for the deflecting roller 12.

Zwischen dieser Wascheinrichtung 8 und dem Dämpfer 1 ist eine zusätzliche VorWaschvorrichtung 16 in unmittelbarer Nähe des Dämpferauslaufs angeordnet. Die heiß aus dem Dämpfer auslaufende Ware 3 wird mit Hilfe einer Umlenkwalze 17, die in unmittelbarer Nähe der Dämpfer-Auslaufwandung 5 oberhalb der Vor-Waschvorrichtung 16 angeordnet ist, nach oben zur Vor-Wascheinrichtung umgelenkt. Von dort läuft dann die Teppichbahn 3 in Transportrichtung der Anlage zur ersten Umlenkwalze 9' der Vor-Waschvorrichtung 16. An dieser Umlenkwalze 9' liegt von unten eine Rakel 18 an, die die Florseite der Teppichbahn beaufschlagt und stärkere Applikationen, wie die für das Gum-Verfahren, abstreift und die Paste in die Auffangrinne 19 laufen läßt. Die Auffangrinne 19 ist mit Spülflüssigkeit kontinuierlich gereinigt. Zweckmäßigerweise verwendet man dazu das Abwasser der Waschvorrichtung 8.An additional pre-washing device 16 is arranged in the immediate vicinity of the damper outlet between this washing device 8 and the damper 1. The product 3, which runs hot out of the damper, is deflected upwards to the pre-washing device with the aid of a deflection roller 17, which is arranged in the immediate vicinity of the damper outlet wall 5 above the pre-washing device 16. From there, the carpet web 3 then runs in the transport direction of the system to the first deflecting roller 9 'of the pre-washing device 16. From this bottom, a doctor blade 18 is applied to this deflecting roller 9', which acts on the pile side of the carpet web and stronger applications such as those for the gum -Procedure, strips and lets the paste run into the gutter 19. The gutter 19 is continuously cleaned with rinsing liquid. The waste water from the washing device 8 is expediently used for this purpose.

Nach dem Abrakeln der stärksten Schmutzschicht von der Teppichbahn wird die Warenbahn auf der Oberseite mit Waschflüsssigkeit aus der Sprühvorrichtung 15' bespritzt und anschließend die Waschflüssigkeit auf der Florseite am Saugbalken 11', also nach Durchströmen der Warenbahn, abgesaugt Selbstverständlich kann die Warenbahn 3 auch hier getaucht werden. Im Anschluß läuft dann die Warenbahn 3 zur angetriebenen Umlenkwalze 10' und dann über mehrere Umlenk- und Steuerwalzen zur eigentlichen Waschvorrichtung 8.After scraping off the thickest layer of dirt from the carpet web, the top of the web is sprayed with washing liquid from the spray device 15 'and then the washing liquid is sucked off on the pile side at the suction bar 11', i.e. after flowing through the web, of course the web 3 can also be immersed here become. Subsequently, the web 3 then runs to the driven deflecting roller 10 'and then via several deflecting and control rollers to the actual washing device 8.

Gemäß dem Ausführungsbeispiel nach Fig. 1 ist die Vor-Waschvorrichtung 16 lotrecht oberhalb eines Bedienungsperson-Durchgangs 21 angeordnet, was den Vorteil der leichteren Zugänglichkeit der Vor-Waschvorrichtung 16 zur Folge hat. Die gesamte Vor-Waschvorrichtung 16 ist von einer Dampfabsaughaube 20 umgeben, um in dieser Haube 20 eine heiße Dampfatmophäre zu erzeugen. An der oberen Stelle setzt der Dampfabsaugschacht 7 an, um keinen Dampf aus dieser Haube 20 unten austreten zu lassen. Mit Vorteil umgibt die vom Dämpferauslaufschlitz 6 nach oben zur Umlenkwalze 17 laufende Ware 3 ein Schacht 22, der durch eine zusätzliche Wandung 23 bewirkt ist. Dadurch gelangt die aus dem Schlitz 6 ausströmende Dampfmenge für die Umgebung unschädlich in die Dampfabsaughaube 20, wo sie die Warenbahn 3 ohne aktive Heizung heiß beläßt. Falls notwendig kann aber der Dampfabsaugschacht 7 auch unten oberhalb des Schlitzes 6 zusätzlich enden, oder der Dämpferauslaßschlitz 6 kann auch höher, z. B. unmittelbar unterhalb der Vor-Waschvorrichtung 16,16' an der Außenwandung 5 angeordnet sein.According to the exemplary embodiment according to FIG. 1, the pre-washing device 16 is arranged vertically above an operator passage 21, which has the advantage that the pre-washing device 16 is easier to access. The entire pre-washing device 16 is surrounded by a steam extraction hood 20 in order to generate a hot steam atmosphere in this hood 20. At the top, the steam suction shaft 7 comes into play so that no steam can escape from this hood 20 at the bottom. Advantageously, the goods 3 running from the damper outlet slot 6 upward to the deflecting roller 17 surrounds a shaft 22, which is caused by an additional wall 23. As a result, the amount of steam flowing out of the slot 6 arrives harmless to the environment in the steam extraction hood 20, where it leaves the web 3 hot without active heating. If necessary, however, the steam suction shaft 7 may also end below the slot 6, or the damper outlet slot 6 may also be higher, e.g. B. can be arranged directly below the pre-washing device 16, 16 'on the outer wall 5.

In Fig. 2 ist lediglich die Vor-Waschvorrichtung 16 in der Konstruktion variiert. Die beiden Umlenkwalzen 9'' und 10'' der Vor-Waschvorrichtung 16 sind dort nicht horizontal nebeneinander angeordnet, sondern schräg übereinander, so daß sich eine bezüglich des Grundrisses der Vor-Waschvorrichtung 16 verkleinerte Version ergibt. Die Folge davon ist, daß die Absaugvorrichtung 11'' nicht von lotrecht unten ansetzt, sondern seitlich. Die Absaughaube 20' ist in dieser Fig. auch kleiner ausgebildet, sie ist nicht über die ganze Vor-Waschvorrichtung gestülpt, sondern saugt lediglich aufsteigenden Dampf oben ab.In Fig. 2, only the pre-washing device 16 is varied in construction. The two deflecting rollers 9 ″ and 10 ″ of the pre-washing device 16 are not arranged horizontally next to one another there, but rather diagonally one above the other, so that there is a reduced version with respect to the outline of the pre-washing device 16. The consequence of this is that the suction device 11 ″ does not start from the bottom vertically, but laterally. The suction hood 20 'is also made smaller in this figure, it is not placed over the entire pre-washing device, but only sucks up rising steam at the top.
