Description

Die Erfindung betrifft eine Behandlungsvorrichtung für mindestens ein Textil gemäß dem Oberbegriff des Anspruchs 1 und ein Verfahren zum Behandeln mindestens eines Textils gemäß dem Oberbegriff des Anspruchs 9.The invention relates to a treatment device for at least one textile according to the preamble of claim 1 and a method for treating at least one textile according to the preamble of claim 9.

Eine solche Vorrichtung weist einen Umlaufförderer zum Fördern des mindestens einen Textils zu einer Behandlungsstation und mindestens einer Halteeinrichtung auf, welche ausgebildet ist, mindestens ein Textil aufzunehmen und zu halten.Such a device has a circulating conveyor for conveying the at least one textile to a treatment station and at least one holding device which is designed to receive and hold at least one textile.

Bei einem solchen Verfahren wird das mindestens eine Textil auf einer Haltevorrichtung angeordnet, welche auf einem Umlaufförderer vorgesehen ist, wobei das Textil mittels des Umlaufförderers einer Druckvorrichtung zustellbar ist.In such a method, the at least one textile is arranged on a holding device which is provided on a circulating conveyor, wherein the textile can be delivered to a printing device by means of the circulating conveyor.

Im Bereich des Textildrucks besteht das andauernde Bedürfnis, die zu bedruckende Oberfläche beim Fördern, insbesondere durch einzelne Druckstationen wie beispielsweise Vorbehandlungs-, Trocknungs- und die eigentliche Druckeinrichtung(en) ortsfest auf dem Fördermittel vorzusehen, um ein Verschieben oder Verrutschen gegenüber einer zuvor definierten relativen Positionierung des Textils gegenüber den Druckstationen zu verhindern. Dem Fachmann sind Mittel zum Fixieren von Textilen bekannt, bei welchen das zu bedruckende Textil in einer Art Rahmenfassung fixiert wird, wobei dieser Rahmen, welcher meist aus einem Metall oder Hartplastik gefertigt ist, in eine Druckvorrichtung eingelegt oder mit einem Fördermittel verrastet wird. Das Fixieren des Textils in dem Rahmen findet hierbei in einem separaten vorgeschalteten Arbeitsschritt statt. Dies stellt einen zusätzlichen Arbeitsschritt dar, welcher den Gesamtprozess langwierig und kostenintensiver gestaltet, als wenn die Fixierung in dem Rahmen ausbliebe.In the field of textile printing, there is a constant need to provide the surface to be printed on the conveyor during conveyance, in particular through individual printing stations such as pretreatment, drying and the actual printing device (s), in order to shift or slip in relation to a previously defined relative To prevent positioning of the textile opposite the printing stations. Means for fixing textiles are known to those skilled in the art, in which the textile to be printed is fixed in a type of frame setting, this frame, which is usually made of metal or hard plastic, is inserted into a printing device or locked to a conveyor. The fixing of the textile in the frame takes place in a separate upstream work step. This represents an additional work step which makes the overall process lengthy and more costly than if it were not fixed in the frame.

Ein gattungsbildender Stand der Technik geht aus der US 2015/016549 A1 hervor. Zur Aufnahme des Textils ist eine L-förmige Halteeinrichtung vorgesehen, welche nur im Bereich eines kurzen Befestigungssteges mit einem Umlaufförderer verbunden ist. Der vom Umlaufförderer beabstandete Aufnahmesteg der Halteeinrichtung kann unerwünscht hohen Biegeverformungen ausgesetzt sein.A generic prior art is based on US 2015/016549 A1 emerged. To receive the textile, an L-shaped holding device is provided which is only connected to a circulating conveyor in the area of a short fastening web. The receiving web of the holding device, which is spaced apart from the circulating conveyor, can be exposed to undesirably high bending deformations.

Weitere Druckvorrichtungen sind aus der US 2013/0293652 A1 und der US 2009/097044 A1 bekannt.Further printing devices are from the US 2013/0293652 A1 and the US 2009/097044 A1 known.

Die vorliegende Erfindung stellt sich daher die Aufgabe, eine Vorrichtung sowie ein Verfahren zum Behandeln eines zu bedruckenden Textils bereitzustellen, mit welchen ein Textil besonders wirtschaftlich und ortsgenau positionierbar ist. The object of the present invention is therefore to provide a device and a method for treating a textile to be printed with which a textile can be positioned in a particularly economical and precise manner.

Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung gemäß dem Anspruch 1 sowie durch ein Verfahren gemäß dem Anspruch 9 gelöst.According to the invention, the object is achieved by a device according to claim 1 and by a method according to claim 9.

Bevorzugte Ausführungsformen der vorliegenden Erfindung sind in den abhängigen Ansprüchen angegeben.Preferred embodiments of the present invention are given in the dependent claims.

Bei der erfindungsgemäßen Vorrichtung ist vorgesehen, dass die mindestens eine Halteeinrichtung an dem Umlaufförderer einen erhabenen Auflagebereich aufweist, welcher eine erhöhte Auflage für zumindest einen Teil des Textils bereitstellt.In the device according to the invention it is provided that the at least one holding device on the circulating conveyor has a raised support area which provides a raised support for at least part of the textile.

Ein erster Grundgedanke der Erfindung besteht darin, ein zu bedruckendes Textil auf einem dafür vorgesehenen Bereich auf einem Fördermittel bereitzustellen, mittels welchem das Textil einer Druckeinrichtung zustellbar ist. Hierbei kann grundsätzlich auf einen üblichen Fixierrahmen, in welchem das Textil zuvor eingespannt wird, um dieses danach auf dem Fördermittel vorzusehen, verzichtet werden. Grundsätzlich kann die Halteeinrichtung hierbei als Teil der Fördereinrichtung ausgebildet sein und einen besonderen Bereich bereitstellen, auf welchem das Textil besonders ortsgenau vorsehbar ist. Die Haltevorrichtung kann hierzu beispielsweise mit einer rutschfesten Beschichtung, insbesondere mit einer Gummierung oder einer anderen gegenüber Textilen adhäsiv wirkenden Oberfläche bereitgestellt sein. Hierdurch kann einem nachträglichen Verschieben oder Verrutschen des positionierten Textils auf der Halteeinrichtung vorgebeugt sein. Selbst bei einem Führungskontakt des Textils mit einem Druckkopf, beispielsweise einem digitalen Inkjetdruckkopf, kann so das Textil auf der Halteeinrichtung ortsfest vorgesehen sein. Die Halteeinrichtung kann hierbei aus Segmenten ausgebildet sein, welche jeweils für sich genommen die adhäsiven Eigenschaften zumindest teilweise aufweisen können. Durch den segmentartigen Aufbau kann insbesondere die Größe der Halteeinrichtung an ein zu bedruckendes Textil angepasst werden. Hierdurch ist es möglich, ein Druckbild besonders hoher Qualität bereitzustellen. Grundsätzlich kann die Halteeinrichtung aus einem formflexiblen Material gebildet sein.A first basic idea of the invention consists in providing a textile to be printed in an area provided for this on a conveying means, by means of which the textile can be delivered to a printing device. In this case, there is basically no need for a conventional fixing frame in which the textile is clamped beforehand in order to then provide it on the conveying means. In principle, the holding device can be designed as part of the conveying device and can provide a special area on which the textile can be provided with a particularly precise location. For this purpose, the holding device can be provided, for example, with a non-slip coating, in particular with a rubber coating or another surface that has an adhesive effect on textiles. This can prevent a subsequent shifting or slipping of the positioned textile on the holding device. Even with a guide contact of the textile with a print head, for example one digital inkjet print head, the textile can thus be provided in a stationary manner on the holding device. The holding device can in this case be formed from segments which, taken individually, can at least partially have the adhesive properties. Due to the segment-like structure, in particular the size of the holding device can be adapted to a textile to be printed. This makes it possible to provide a print image of particularly high quality. In principle, the holding device can be formed from a material that is flexible in shape.

Erfindungsgemäß wird das zu bedruckende Textil nicht in einem Fixierrahmen vorgesehen, welcher einer Druckeinrichtung oder einer Fördereinrichtung zustellbar ist, sondern vielmehr direkt auf dem Fördermittel beziehungsweise auf einem dafür vorgesehenen Aufnahmebereich, nämlich einer Halteeinrichtung, angeordnet. Dadurch entfällt der zusätzliche Arbeitsschritt des anfänglichen Anordnens/Verspannens in einem Fixierrahmen.According to the invention, the textile to be printed is not provided in a fixing frame that can be delivered to a printing device or a conveyor, but rather is arranged directly on the conveyor or on a receiving area provided for this purpose, namely a holding device. This eliminates the additional work step of initially arranging / bracing in a fixing frame.

Nach der vorliegenden Erfindung ist es vorgesehen, dass die Halteeinrichtung mit Segmenten gebildet ist, welche mit dem Umlaufförderer verbunden sind. Grundsätzlich können die Segmente der Halteeinrichtung, also des Aufnahmebereichs, auf dem Umlaufförderer aufgelegt sein. Bevorzugt ist es jedoch, dass die Halteeinrichtung über Nuten, Verschraubungen, Verschweißung, Verklebung, Verrastung oder ähnliches mit dem Umlaufförderer, vorzugsweise lösbar, verbunden sind. Hierdurch können die einzelnen Segmente mit dem Umlaufförderer nach dem Verbinden der Segmente mit dem Umlaufförderer eine Einheit bilden. Durch die Segmente kann der Aufnahmebereich für Textil auf dem Umlaufförderer gebildet sein.According to the present invention it is provided that the holding device is formed with segments which are connected to the circulating conveyor. In principle, the segments of the holding device, that is to say of the receiving area, can be placed on the circulating conveyor. It is preferred, however, that the holding device is connected to the circulating conveyor, preferably detachably, via grooves, screw connections, welding, gluing, latching or the like. As a result, the individual segments can form a unit with the circulating conveyor after the segments have been connected to the circulating conveyor. The receiving area for textile on the circulating conveyor can be formed by the segments.

Nach einer besonders zweckmäßigen Weiterbildung der vorliegenden Erfindung ist es vorgesehen, dass der Umlaufförderer, ein Endlosförderband umfasst. Da ein zu bedruckendes Textil direkt auf der Halteeinrichtung auf dem Umlaufförderer vorsehbar ist, kann es zweckmäßig sein, den Umlaufförderer als kontinuierlich textiltransportierende Einrichtung der Positionierungsvorrichtung vorzusehen. Hierbei kann an dem Umlaufförderer ein erster Bereich vorgesehen sein, in welchem die Halteeinrichtung auf dem Umlaufförderer mit Textil bestückt wird. In Förderrichtung des Umlaufförderers nach dem ersten Bereich kann ein zweiter Bereich vorgesehen sein, in welchem Behandlungseinrichtungen entlang des Umlaufförderers für zu bedruckendes Textil vorgesehen sein können. Hierbei können insbesondere Vorbehandlungseinrichtungen, Trocknungseinrichtungen und Druckeinrichtungen, vorzugsweise Druckeinrichtungen, welche nach dem Inkjetdruckverfahren, also nach einem digitalen Druckverfahren arbeiten, vorgesehen sein. In Förderrichtung hinter dem zweiten Bereich kann entlang des Umlaufförderers ein Entnahmebereich vorgesehen sein, in welchem das behandelte, vorzugsweise bedruckte Textil von der Halteeinrichtung auf dem Umlaufförderer entfernbar ist.According to a particularly expedient development of the present invention, it is provided that the circulating conveyor comprises an endless conveyor belt. Since a textile to be printed can be provided directly on the holding device on the circulating conveyor, it can be expedient to provide the circulating conveyor as a continuously textile-transporting device of the positioning device. Here, a first area can be provided on the circulating conveyor, in which the holding device on the circulating conveyor is equipped with textile. In the conveying direction of the circulating conveyor after the first area, a second area can be provided in which treatment devices can be provided along the circulating conveyor for textile to be printed. In particular, pretreatment devices, drying devices and printing devices, preferably printing devices, which work according to the inkjet printing method, that is to say according to a digital printing method, can be provided. In the conveying direction behind the second area, a removal area can be provided along the circulating conveyor, in which the treated, preferably printed textile can be removed from the holding device on the circulating conveyor.

Aufgrund einer bevorzugten Ausbildung des Umlaufförderers als Endlosförderband, kann der Umlaufförderer mit der Halteeinrichtung, vorzugsweise nach dem dritten Bereich, in einfacher Weise zu dem ersten Bereich zum Bestücken der Halteeinrichtung auf dem Umlaufförderer mit Textil rückgeführt werden. Hierdurch kann ein kontinuierlicher Endlosprozess zum Fördern von Textil bereitgestellt sein.Due to a preferred design of the circulating conveyor as an endless conveyor belt, the circulating conveyor with the holding device, preferably after the third area, can easily be returned to the first area for loading the holding device on the circulating conveyor with textile. In this way, a continuous endless process for conveying textile can be provided.

Nach der Erfindung ist vorgesehen, dass die Segmente rippenartig ausgebildet sind und sich quer zu einer Förderrichtung erstrecken. Insbesondere dann, wenn die Segmente der Halteeinrichtung auf dem Umlaufförderer in voranstehend beschriebener Weise fixiert sind, können diese auf dem Umlaufförderer auch bei einem Zustellen der Halteeinrichtung aus einem beispielsweise dritten Bereich nach dem Entnehmen des Textils zu einem ersten Bereich, in welchem die Halteeinrichtung mit Textil bestückt wird, auf dem Umlaufförderer verbleiben. Der Umlaufförderer, welcher insbesondere als Endlosförderband ausgebildet ist, kann während des Förderns eine nach oben weisenden Ablagefläche bereitstellen, auf welcher beispielsweise die Halteeinrichtung Textil halten kann. Am Ende des Umlaufförderers kann eine Umlenkrolle oder ein anderes Mittel zum Ändern beziehungsweise Umkehren der Laufrichtung des Fördermittels angeordnet sein, mittels welcher das Endlosförderband vorzugsweise parallel zu der fördernden Oberseite einem ersten Bereich gegenläufig rückgeführt wird. Hierbei kann die Ablagefläche nach unten weisen. In dem ersten Bereich kann ebenfalls eine Umlenkrolle vorgesehen sein, welche die Oberfläche des Umlaufförderers, insbesondere des Förderbandes, von einer nach unten gerichteten Orientierung beim Rückführen wieder zurück in eine nach oben gerichtete Orientierung, bei welcher die Auflagefläche wieder nach oben gerichtet ist, umlenken kann. Einem Herunterfallen von Segmenten von dem Umlaufförderer kann so vorgebeugt sein.According to the invention it is provided that the segments are rib-like and extend transversely to a conveying direction. In particular if the segments of the holding device are fixed on the circulating conveyor in the manner described above, they can also be used on the circulating conveyor when the holding device is infeed from a third area, for example, after the textile has been removed to a first area in which the holding device with textile is loaded, remain on the circulating conveyor. The circulating conveyor, which is designed in particular as an endless conveyor belt, can provide an upwardly pointing storage surface during conveying, on which, for example, the holding device can hold textile. At the end of the circulating conveyor, a pulley or some other means for changing or reversing the direction of travel of the conveyor can be arranged, by means of which the endless conveyor belt is preferably returned parallel to the conveying upper side of a first area in opposite directions. The shelf can face downwards. A deflection roller can also be provided in the first area, which can deflect the surface of the circulating conveyor, in particular the conveyor belt, from a downward orientation when it is returned back to an upward orientation in which the support surface is directed upward again . This can prevent segments from falling off the circulating conveyor.

Insbesondere beim Vorsehen von Umlenkrollen beziehungsweise Umlenkmitteln ist es zweckmäßig, dass die Halteeinrichtung, welche eine Oberfläche für ein zu bestückendes Textil bereitstellt, dem Verlauf des Förderbandes auch dann folgen kann, wenn dieses von einer ebenen Ausrichtung abweicht. Dies kann insbesondere dann der Fall sein, wenn der Umlaufförderer, insbesondere das Endlosförderband, über mindestens eine Umlenkrolle, vorzugsweise zwei Umlenkrollen, gefördert wird und hierbei die Krümmung der Rolle nachvollzieht. Insbesondere im Bereich der Umlenkrollen kann die Fläche des Umlaufförderers eine von der Ebene abweichende Oberfläche aufweisen. Durch den segmentartigen Aufbau, insbesondere die rippenartige Ausbildung der Segmente quer zum Umlaufförderer ist die Halteeinrichtung ausgebildet, sich der Änderung der Förderrichtung und damit einer Krümmung der Förderrichtung, insbesondere entlang der Umlenkrollen, anzupassen. Eine Breite der rippenartigen Segmente, also eine Länge in Förderrichtung, kann hierbei auf den Radius der Umlenkrolle angepasst sein und eine maximale Breite aufweisen, welche ein Abrollen des Umlaufförderers auf der Umlenkrolle noch ermöglicht, ohne dass es zu übermäßigen Spannungen in dem Förderband kommt. Gegenüber einem klassischen Halterahmen für Textil weist die Halteeinrichtung den Vorteil auf, dass beim Umleiten, also Rückführen des Umlaufförderers die Halteeinrichtung nicht von dem Umlaufförderer entfernt werden muss, sondern mit der Förderbewegung des Umlaufförderers einem ersten Bereich zum Bestücken mit Textil rückführbar ist.In particular when providing deflection rollers or deflection means, it is expedient that the holding device, which provides a surface for a textile to be equipped, can also follow the course of the conveyor belt when it deviates from a planar orientation. This can be the case in particular when the circulating conveyor, in particular the endless conveyor belt, is conveyed via at least one deflection roller, preferably two deflection rollers, and in doing so follows the curvature of the roller. Especially in the area of the pulleys the surface of the circulating conveyor can have a surface deviating from the plane. Due to the segment-like structure, in particular the rib-like design of the segments transversely to the circulating conveyor, the holding device is designed to adapt to the change in the conveying direction and thus a curvature of the conveying direction, in particular along the deflecting rollers. A width of the rib-like segments, i.e. a length in the conveying direction, can be adapted to the radius of the deflection roller and have a maximum width which still allows the circulating conveyor to roll on the deflection roller without excessive tension occurring in the conveyor belt. Compared to a classic holding frame for textiles, the holding device has the advantage that when diverting, i.e. returning, the circulating conveyor, the holding device does not have to be removed from the circulating conveyor, but can be returned to a first area for loading textile with the conveying movement of the circulating conveyor.

Ein klassischer Spannrahmen zum Halten von Textil ist nicht ausgebildet, die Umlenkbewegung entlang einer Umlenkrolle, beispielsweise bei einem Endlosförderband nachzuvollziehen, da dieser groß und starr ist. Dies würde das Förderband oder den Rahmen beschädigen. Ein solcher dem Fachmann bekannter Spannrahmen wird regelmäßig nach dem Bedrucken vom Förderband entfernt und anschließend zerlegt, um das bedruckte beziehungsweise behandelte Textil von diesem zu entfernen. Der zerlegte Rahmen wird separat mit neuem Textil bestückt und anschließend der Druckeinrichtung wieder zugeführt. Im Gegensatz hierzu kann erfindungsgemäß die Halteeinrichtung dauerhaft auf dem Förderband vorgesehen sein, vorzugsweise lösbar mit diesem verbunden sein und/oder nach einem Entfernen von Textil von der Halteeinrichtung auf dem Umlaufförderer verbleiben, selbst dann, wenn der Umlaufförderer über Umlenkrollen geleitet wird und/oder die Oberfläche des Förderbandes nach unten zeigt, wodurch lose Teile von dem Umlaufförderer herabfallen würden.A classic clamping frame for holding textile is not designed to reproduce the deflection movement along a deflection roller, for example in the case of an endless conveyor belt, since this is large and rigid. This would damage the conveyor belt or the frame. Such a tenter frame known to the person skilled in the art is regularly removed from the conveyor belt after printing and then dismantled in order to remove the printed or treated textile therefrom. The dismantled frame is fitted with new textile separately and then fed back to the printing device. In contrast to this, according to the invention, the holding device can be permanently provided on the conveyor belt, preferably detachably connected to it and / or remain on the circulating conveyor after removing textile from the holding device, even if the circulating conveyor is guided over deflection rollers and / or the Surface of the conveyor belt facing downwards, whereby loose parts would fall from the rotary conveyor.

Besonders bevorzugt ist es nach einer Weiterbildung der Erfindung, dass die Segmente formflexibel ausgebildet sind. Eine aus Segmenten aufgebaute Halteeinrichtung kann eine von der Ebene abweichende Oberfläche bilden. Ebenfalls können die einzelnen Segmente reversibel, vorzugsweise formelastisch, verformbar sein. Hierdurch kann beispielsweise eine seitliche Verformung, beispielsweise bei einem Umlenken der Fördereinheit innerhalb der Förderebene, beispielsweise zu einer rechten oder linken Seite, durch die flexiblen Segmente ebenfalls nachvollzogen werden.According to a development of the invention, it is particularly preferred that the segments are designed to be flexible in shape. A holding device made up of segments can form a surface deviating from the plane. The individual segments can also be reversibly, preferably shape-elastic, deformable. In this way, for example, a lateral deformation, for example in the event of a deflection the conveyor unit within the conveyor level, for example to a right or left side, can also be traced by the flexible segments.

Besonders bevorzugt ist es nach einer Weiterbildung der Erfindung, dass eine Andrückeinrichtung vorgesehen ist, welche ausgebildet ist, das mindestens eine Textil auf der mindestens einen Halteeinrichtung zusätzlich zu fixieren. Ergänzend oder alternativ zu einer adhäsiven Oberfläche der Halteeinrichtung kann der Halteeinrichtung eine Andrückeinrichtung zustellbar sein, welche das Textil auf der Halteeinrichtung ortsfest festlegt. Die Andrückeinrichtung kann hierbei ebenfalls als eine das Textil vorbereitende Einrichtung vorgesehen sein, welche das Textil auf der Halteeinrichtung spannt und/oder leicht dehnt und somit beispielsweise eine besonders glatte Oberfläche des Textils, vorzugsweise faltenfreie Oberfläche, bereitstellt.According to a further development of the invention, it is particularly preferred that a pressing device is provided which is designed to additionally fix the at least one textile on the at least one holding device. In addition to or as an alternative to an adhesive surface of the holding device, the holding device can be supplied with a pressing device which fixes the textile in a stationary manner on the holding device. The pressing device can also be provided as a device preparing the textile, which tensions the textile on the holding device and / or stretches it slightly and thus provides, for example, a particularly smooth surface of the textile, preferably a wrinkle-free surface.

Vorzugsweise ist es vorgesehen, dass die Andrückeinrichtung mindestens ein Andrückelement aufweist, welches dem Umlaufförderer und/oder der mindestens einen Halteeinrichtung zumindest bereichsweise zustellbar ist, wobei das Textil mittels des Andrückelements auf der Halteeinrichtung festlegbar ist. Das Andrückelement kann einem Bereich auf und/oder in der unmittelbaren Umgebung der Halteeinrichtung direkt auf dem Umlaufförderer zustellbar sein. Hierbei kann das zu bedruckende Textil zwischen dem Andrückelement und der Halteeinrichtung vorsehbar sein. Alternativ oder zusätzlich kann das mindestens eine Andrückelement dem Umlaufförderer zustellbar sein. Wobei der Zustellbereich vorzugsweise in unmittelbarer Umgebung zur Halteeinrichtung vorgesehen ist. Das Textil kann grundsätzlich größer sein als die vorgesehene Halteeinrichtung zum Halten des Textils. Der darüber hinausragende Bereich des Textils kann auf einem zur Halteeinrichtung angrenzenden Bereich des Umlaufförderers aufliegen. Bei einem Zustellen des Andrückelements zu dem Umlaufförderer kann in einem solchen Fall das Textil zwischen dem Andrückelement und dem Umlaufförderer festgelegt sein, wodurch das Textil insgesamt auf der Halteeinrichtung festlegbar ist. Das Andrückelement kann parallel zur Fördereinrichtung vorzugsweise mit einer zum Umlaufförderer gleichförmigen Zustellgeschwindigkeit vorgesehen sein.It is preferably provided that the pressing device has at least one pressing element which can be delivered to the circulating conveyor and / or the at least one holding device at least in some areas, the textile being able to be fixed on the holding device by means of the pressing element. The pressure element can be delivered to an area on and / or in the immediate vicinity of the holding device directly on the circulating conveyor. Here, the textile to be printed can be provided between the pressure element and the holding device. Alternatively or additionally, the at least one pressure element can be delivered to the circulating conveyor. The delivery area is preferably provided in the immediate vicinity of the holding device. The textile can in principle be larger than the holding device provided for holding the textile. The area of the textile protruding beyond this can rest on an area of the circulating conveyor adjoining the holding device. In such a case, when the pressure element is fed to the circulating conveyor, the textile can be fixed between the pressure element and the circulating conveyor, whereby the textile as a whole can be fixed on the holding device. The pressure element can be provided parallel to the conveyor device, preferably with a delivery speed that is uniform to that of the circulating conveyor.

Nach einer besonders zweckmäßigen Weiterbildung der Erfindung ist es vorgesehen, dass das mindestens eine Andrückelement mit mindestens einem Endlosfördermittel ausgebildet ist. In ähnlicher Weise wie die Fördereinheit kann auch das Andrückelement als Umlaufförderer oder Endlosförderband vorgesehen sein, welches bevorzugt von oberhalb des Umlaufförderers zumindest einem Bereich des Umlaufförderers zustellbar ist. Besonders bevorzugt wird das Andrückelement des Umlaufförderers mit der Halteeinrichtung zumindest bereichsweise zugestellt, vorzugsweise in einem Bereich, welcher in Förderrichtung hinter dem Bereich liegt, in welchem die Halteeinrichtung mit Textil bestückbar ist. Das Endlosfördermittel beziehungsweise das Andrückelement kann hierbei über Umlenkrollen vorzugsweise von oben der Fördereinrichtung zustellbar sein, parallel zur Fördereinrichtung, zumindest bereichsweise umlenkbar sein und/oder am Ende des Zustellbereichs über weitere Umlenkmittel, vorzugsweise nach oben von der Fördereinrichtung weg ablenkbar sein. Hierdurch kann eine bereichsweise Zustellung des Andrückelements zu der Fördereinrichtung bereitgestellt sein. Das mindestens eine Andrückelement kann hierbei in etwa die Bewegungsgeschwindigkeit des Umlaufförderers aufweisen.According to a particularly expedient development of the invention, it is provided that the at least one pressure element is provided with at least one endless conveyor is trained. In a manner similar to the conveyor unit, the pressure element can also be provided as a circulating conveyor or endless conveyor belt, which can preferably be delivered from above the circulating conveyor to at least one area of the circulating conveyor. Particularly preferably, the pressure element of the circulating conveyor with the holding device is fed in at least in some areas, preferably in an area which, in the conveying direction, lies behind the area in which the holding device can be equipped with textile. The endless conveying means or the pressure element can in this case be able to be delivered to the conveying device via deflection rollers, preferably from above, parallel to the conveying device, at least partially deflectable and / or at the end of the infeed area via further deflecting means, preferably upwards away from the conveying device. In this way, a regional delivery of the pressure element to the conveying device can be provided. The at least one pressure element can have approximately the speed of movement of the circulating conveyor.

Nach einer besonders zweckmäßigen Weiterentwicklung der vorliegenden Erfindung ist es vorgesehen, dass die Andrückeinrichtung mindestens zwei Andrückelemente aufweist, welche in etwa parallel zueinander vorgesehen sind. Die Andrückelemente können beispielsweise in Förderrichtung rechts und links beziehungsweise in einem vorderen und hinteren Bereich mit der Halteeinrichtung beziehungsweise unmittelbar neben der Halteeinrichtung mit dem Umlaufförderer in Kontakt kommen. Hierdurch kann ein Bereich bereitgestellt sein, welcher zwischen den Kontaktbereichen der beiden Andrückelemente liegt und in welchen das Textil besonders ortsfest auf der Halteeinrichtung vorgesehen ist. Es versteht sich, dass, wenn die Andrückelemente nach der Beschreibung der Erfindung die Halteeinrichtung oder der Umlaufförderer kontaktieren, im laufenden Betrieb der Positioniereinrichtung ein Textil zwischen den Einrichtungen vorgesehen ist und daher der Kontakt der Einrichtungen und Elemente zumindest bereichsweise kein direkter Kontakt sein muss. Vorzugsweise sind die mindestens zwei Andrückelemente ebenfalls als Endlosfördermittel ausgebildet, welche in etwa parallel zu dem Umlaufförderer führbar sind, wodurch zumindest bereichsweise ein Parallellauf der beiden Andrückelemente und des Umlaufförderers bereitgestellt sein kann. In diesem können die Andrückelemente der Halteeinrichtung und/oder dem Umlaufförderer zustellbar sein, wodurch das Textil teilweise zwischen Halteeinrichtung und Andrückelement und/oder dem Umlaufförderer und Andrückelement festlegbar sein kann.According to a particularly expedient further development of the present invention, it is provided that the pressing device has at least two pressing elements which are provided approximately parallel to one another. The pressing elements can, for example, come into contact with the holding device on the right and left or in a front and rear area in the conveying direction or with the circulating conveyor directly next to the holding device. In this way, an area can be provided which lies between the contact areas of the two pressure elements and in which the textile is provided in a particularly stationary manner on the holding device. It goes without saying that if the pressure elements contact the holding device or the circulating conveyor according to the description of the invention, a textile is provided between the devices during operation of the positioning device and therefore the contact of the devices and elements does not have to be direct contact, at least in some areas. The at least two pressure elements are preferably also designed as endless conveying means, which can be guided approximately parallel to the circulating conveyor, whereby a parallel run of the two pressure elements and the circulating conveyor can be provided at least in some areas. In this, the pressure elements of the holding device and / or the circulating conveyor can be delivered, whereby the textile partially between Holding device and pressure element and / or the circulating conveyor and pressure element can be fixed.

Besonders zweckmäßig ist es nach einer Weiterbildung der Erfindung, dass mindestens zwei Andrückelemente mit mindestens zwei Verbindungselementen verbunden sind, mit welchen sie mindestens eine Öffnung bilden, welche vorzugsweise etwa der Kontur der mindestens einen Halteeinrichtung auf dem Umlaufförderer entspricht. Grundsätzlich können die Andrückelemente als Endlosförderbänder aus einem geeigneten Material, beispielsweise einem natürlichen oder künstlichen Polymer, vorzugsweise einem Elastomer oder einem Textil, gebildet sein. Die zwischen den mindestens zwei Verbindungselementen und den zwei Andrückelementen gebildete Öffnung kann der Form der Halteeinrichtung in etwa entsprechen, kann jedoch von ihrer Größe abweichen. Wird die Öffnung der Halteeinrichtung zugestellt, kann diese einen umschlossenen Bereich bilden, innerhalb welchem ein zu bedruckender Bereich des Textils liegen kann. Dieser Bereich kann durch die Andrückeinrichtung auf der Halteeinrichtung, vorzugsweise flächig, gespannt werden, wodurch einem Verrutschen oder einer Faltenbildung in Förderrichtung und/oder quer zu derselbigen besonders sicher vorgebeugt sein kann. Vorzugsweise kann das Textil auf der Halteeinrichtung mittels des Umlaufförderers einer Textilbehandlungseinrichtungen wie voranstehend beschrieben zugeführt werden, während das mindestens eine Andrückelement, vorzugsweise die zwei Andrückelemente mit Verbindungselementen, der Halteeinrichtung zugestellt sind. Die Position des Textils während eines Behandelns/Bedruckens kann somit auf der Halteeinrichtung festgelegt sein. Die Andrückeinrichtung, welche mit zwei Andrückelementen und mindestens zwei Verbindungselementen gebildet sein kann, kann insbesondere als Profilband vorgesehen sein, welche Öffnungen aufweist, die in etwa der Form und/oder der Größe der Halteeinrichtung auf der Fördereinrichtung entsprechen.According to a development of the invention, it is particularly expedient that at least two pressure elements are connected to at least two connecting elements with which they form at least one opening which preferably corresponds approximately to the contour of the at least one holding device on the circulating conveyor. In principle, the pressure elements can be formed as endless conveyor belts from a suitable material, for example a natural or artificial polymer, preferably an elastomer or a textile. The opening formed between the at least two connecting elements and the two pressure elements can approximately correspond to the shape of the holding device, but can differ from its size. If the opening of the holding device is closed, it can form an enclosed area within which an area of the textile to be printed can lie. This area can be tensioned by the pressing device on the holding device, preferably flat, whereby slipping or wrinkling in the conveying direction and / or transversely to the same can be prevented particularly reliably. The textile on the holding device can preferably be fed to a textile treatment device as described above by means of the circulating conveyor, while the at least one pressure element, preferably the two pressure elements with connecting elements, are fed to the holding device. The position of the textile during treatment / printing can thus be fixed on the holding device. The pressing device, which can be formed with two pressing elements and at least two connecting elements, can in particular be provided as a profiled band which has openings which roughly correspond to the shape and / or size of the holding device on the conveying device.

Besonders bevorzugt ist es nach einer Weiterbildung der Erfindung, dass die Andrückeinrichtung dem Umlaufförderer zumindest in einem Bereich zustellbar ist, in welchen das mindestens eine Textil behandelbar, vorzugsweise bedruckbar und/oder trockenbar ist. Beispielsweise über Umlenkrollen kann die Andrückeinrichtung der Fördereinrichtung bereichsweise zustellbar sein, vorzugsweise von oberhalb der Fördereinrichtung.According to a further development of the invention, it is particularly preferred that the pressing device can be delivered to the circulating conveyor at least in an area in which the at least one textile can be treated, preferably printed and / or dried. For example, the pressing device of the conveying device can be adjusted in areas via deflection rollers, preferably from above the conveying device.

Bei dem erfindungsgemäßen Verfahren ist vorgesehen, dass das Textil auf der Halteeinrichtung erhöht angerordnet wird und der Halteeinrichtung eine Andrückeinrichtung zugestellt wird, welche das Textil auf der Halteeinrichtung fixiert.In the method according to the invention it is provided that the textile is arranged in an elevated position on the holding device and a pressing device is fed to the holding device, which fixes the textile on the holding device.

Nach einem weiteren Grundgedanken der vorliegenden Erfindung ist es vorgesehen, an Stelle eines klassischen Halterahmens, welcher einer Druckeinrichtung zugestellt wird, einen Umlaufförderer mit einer Halteeinrichtung bereitzustellen, wobei die Halteeinrichtung eine Oberfläche für eine Auflage eines zu bedruckenden Textils bereitstellen kann. Die Halteeinrichtung kann hierbei als Teil des Umlaufförderers ausgebildet sein, wobei die Halteeinrichtung ausgebildet ist, Textil besonders ortsfest auf deren erhöhten Oberfläche zu halten. Zusätzlich kann dem Textil auf der Halteeinrichtung eine Andrückeinrichtung zugestellt werden, wobei das Textil zwischen der Halteeinrichtung und der Andrückeinrichtung ortsfest vorgesehen werden kann.According to a further basic concept of the present invention, instead of a classic holding frame which is delivered to a printing device, a circulating conveyor with a holding device is provided, wherein the holding device can provide a surface for a support of a textile to be printed. The holding device can be designed as part of the circulating conveyor, the holding device being designed to hold textile in a particularly stationary manner on its raised surface. In addition, a pressing device can be delivered to the textile on the holding device, it being possible for the textile to be provided in a stationary manner between the holding device and the pressing device.

Nach einer bevorzugten Weiterbildung der vorgesehenen Erfindung ist es vorgesehen, dass das Textil während des Bedruckens zwischen Halteeinrichtung und Andrückeinrichtung vorgesehen wird. Die Andrückeinrichtung kann der Halteeinrichtung beziehungsweise dem Umlaufförderer bereichsweise zugestellt werden. Vorzugsweise liegt der Zustellbereich auf dem Umlaufförderer in Förderrichtung hinter einem Bereich, in welchem Textil auf der Halteeinrichtung vorgesehen wird. Einrichtungen zum Behandeln des auf der Halteeinrichtung vorgesehen Textils können vorzugsweise in einem Bereich des Umlaufförderers vorgesehen sein, in welcher die Andrückeinrichtung dem Umlaufförderer und/oder der Halteeinrichtung zugestellt ist. In einem Bereich hinter den Behandlungseinrichtungen für Textil auf der Halteeinrichtung kann die Andrückeinrichtung von der Fördereinrichtung beziehungsweise von der Halteeinrichtung abgeführt werden, wodurch das Textil für eine Entnahme freigegeben wird.According to a preferred development of the proposed invention, it is provided that the textile is provided between the holding device and the pressing device during printing. The pressing device can be fed to the holding device or the circulating conveyor in areas. The delivery area on the circulating conveyor is preferably located in the conveying direction behind an area in which textile is provided on the holding device. Devices for treating the textile provided on the holding device can preferably be provided in an area of the circulating conveyor in which the pressing device is fed to the circulating conveyor and / or the holding device. In an area behind the treatment devices for textile on the holding device, the pressing device can be removed from the conveying device or from the holding device, as a result of which the textile is released for removal.

Vorzugsweise weist die Andrückeinrichtung mindestens zwei Andrückelemente auf, welche der Halteeinrichtung als Endlosfördermittel zugestellt werden. Die Endlosfördermittel können vorzugsweise auf gegenüberliegenden Seiten des Druckbereichs des Textils, also vor und hinter beziehungsweise rechts und links von dem Druckbereich, vorgesehen werden, wodurch eine besonders vorteilhafte Fixierung des Textils auf der Halteeinrichtung erreicht werden kann.The pressing device preferably has at least two pressing elements which are fed to the holding device as endless conveying means. The endless conveying means can preferably be provided on opposite sides of the printing area of the textile, that is to say in front of and behind or to the right and left of the printing area, whereby a particularly advantageous fixation of the textile on the holding device can be achieved.

Besonders bevorzugt ist es vorgesehen, dass die mindestens zwei Andrückelemente dem Textil zwischen Halteeinrichtung oder dem Umlaufförderer außerhalb eines Druckbereichs zugestellt werden.It is particularly preferably provided that the at least two pressure elements are fed to the textile between the holding device or the circulating conveyor outside of a pressure area.

In der Zeichnung wird nachfolgend die Erfindung weiter erläutert. In der Figur zeigt:

Fig. 1
eine perspektivische Ansicht auf die erfindungsgemäße Positioniervorrichtung mit Andrückeinrichtung und Behandlungseinrichtungen.
The invention is further explained below in the drawing. In the figure shows:
Fig. 1
a perspective view of the positioning device according to the invention with pressing device and treatment devices.

Fig. 1 zeigt eine erfindungsgemäße Behandlungsvorrichtung 10. Diese weist einen Umlaufförderer 21 auf, welche mit einem Umlaufförderer 21 gebildet sein kann. Diese kann insbesondere als Endlosförderband ausgebildet sein, wobei der Umlaufförderer 21 zwischen Umlenkrollen 22 zum Bilden eines geschlossenen Kreislaufsystems ausgebildet sein kann. Auf dem Umlaufförderer 20, insbesondere dem Umlaufförderer 21 kann mindestens eine Halteeinrichtung 30 vorgesehen sein. Diese kann segmentartig mit einzelnen Segmenten 31 gebildet sein, welche gemeinsam eine erhöhte Auflageoberfläche 32 für ein zu bedruckendes Textil bereitstellen können. Fig. 1 shows a treatment device 10 according to the invention. This has a circulating conveyor 21, which can be formed with a circulating conveyor 21. This can in particular be designed as an endless conveyor belt, wherein the circulating conveyor 21 can be designed between deflection rollers 22 to form a closed circuit system. At least one holding device 30 can be provided on the circulating conveyor 20, in particular the circulating conveyor 21. This can be formed segment-like with individual segments 31, which together can provide a raised support surface 32 for a textile to be printed.

Die Halteeinrichtung kann hierbei eine beliebige Form aufweisen. Besonders zweckmäßig ist eine in etwa rechteckige, kreisförmige oder ovale Form der Halteeinrichtung, entsprechend einem Behandlungsbereich auf dem Textil 60.The holding device can have any shape. An approximately rectangular, circular or oval shape of the holding device, corresponding to a treatment area on the textile 60, is particularly expedient.

Die einzelnen Segmente 31 der Halteeinrichtung 30 sind auf der Oberfläche der Fördereinrichtung 20 vorzugsweise auf dem Umlaufförderer 21 vorgesehen. Diese können insbesondere lösbar mit seiner Oberfläche verbunden sein. Wie insbesondere im linken Bereich der Fig. 1 verdeutlicht, ermöglicht der segmentartige Aufbau der Halteeinrichtung 30, dass diese auch bei einer von der Ebenen abweichenden Oberfläche, also einem Verbiegen oder Krümmen der Halteeinrichtung 30, spannungsfrei auf der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 vorgesehen werden kann. Im Vergleich zu einer durchgängigen steifen Vorrichtung, wie beispielsweise einem Fixierelement oder Spannrahmen werden somit Spannungen in der Halteeinrichtung 30, einem Brechen oder Abplatzen der Halteeinrichtung 30 von der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 vorgebeugt. Oberhalb der Fördereinrichtung (20) beziehungsweise dem Umlaufförderer 21 kann eine Andrückeinrichtung 40 vorgesehen sein. Diese kann mindestens ein Andrückelement 41 aufweisen, welches in Fig. 1 als Förderband beziehungsweise Profilband mit Ausnehmungen dargestellt ist. Dieses Förderband ist als Endlosfördermittel ausgebildet und kann über die Umlenkrollen 43 einer Oberfläche der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 zugestellt werden. Hierbei kann das mindestens eine Andrückelement 41 der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 im Bereich der Halteeinrichtung 30 zugestellt werden. Das Andrückelement 41 kann hierbei wahlweise von oberhalb der Halteeinrichtung 30 oder seitlich zu dieser also direkt von oberhalb der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 zustellbar sein.The individual segments 31 of the holding device 30 are provided on the surface of the conveyor device 20, preferably on the circulating conveyor 21. These can in particular be releasably connected to its surface. As is particularly the case in the left area of the Fig. 1 clarified, the segment-like structure of the holding device 30 enables it to be provided free of tension on the conveying device 20 or the circulating conveyor 21 even if the surface deviates from the plane, i.e. if the holding device 30 is bent or curved. In comparison to a continuous, rigid device such as a fixing element or tensioning frame, tension in the holding device 30, breakage or flaking of the holding device 30 from the conveyor 20 or the circulating conveyor 21 are prevented. Above the conveyor (20) or the circulating conveyor 21 can a pressing device 40 may be provided. This can have at least one pressure element 41, which in Fig. 1 is shown as a conveyor belt or profile belt with recesses. This conveyor belt is designed as an endless conveyor and can be delivered to a surface of the conveyor device 20 or the circulating conveyor 21 via the deflection rollers 43. In this case, the at least one pressure element 41 of the conveying device 20 or the circulating conveyor 21 can be fed in the area of the holding device 30. The pressure element 41 can here optionally be able to be delivered from above the holding device 30 or to the side of it, that is, directly from above the conveyor device 20 or the circulating conveyor 21.

Wie aus Fig. 1 hervorgeht, ist ein Textil 60 auf einer Halteeinrichtung 30 vorgesehen, wobei ein Teil des Textils 60 - hier ein T-Shirt - über die Halteeinrichtung 20 überlappt und direkt auf der Fördereinrichtung 20, insbesondere dem Umlaufförderer 21 aufliegt. Das mindestens eine Andrückelement 41 kann hierbei direkt auf der Halteeinrichtung 30 oder rechts beziehungsweise links von der Halteeinrichtung 30 direkt auf der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 vorgesehen werden, wobei das Textil zwischen dem mindestens einen Andrückelement 41 und der Halteeinrichtung 30 und/oder der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 vorgesehen werden kann. Hierdurch kann das Textil zwischen den jeweiligen Oberflächen der Einrichtungen und Elemente verspannt werden. Weiterhin kann die Andrückeinheit 40 mindestens ein Verbindungselement 44 aufweisen, welches ein erstes Andrückelement 41 und ein zweites Andrückelement 42 miteinander verbindet. Die beiden Andrückelemente 41, 42 werden hierbei vorzugsweise parallel zueinander geführt und der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 der Behandlungsvorrichtung 10 zugestellt. Die Verbindungselemente 44 können hierbei mit den Andrückelementen 41 und 42 mindestens eine Öffnung 45 bilden, welche in etwa der Form der Halteeinrichtung 30 entspricht. Besonders bevorzugt ist ein Profilband vorgesehen, welches die Öffnungen 45 aufweist. Über die Rollen 43 können die Andrückelemente 41, 42 der Oberfläche der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 zustellbar sein. Die Andrückelemente 41, 42 der Andrückeinrichtung 40 können insbesondere einem Bereich der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 zustellbar sein, welche in Förderrichtung hinter einem Bereich liegt, in welchem die Halteeinrichtung 30 mit einem Textil 60 bestückbar ist. In den Bereich, hier mit I gekennzeichnet, in welchen die Andrückelemente 41, 42 beziehungsweise das Profilband der Andrückeinheit 40 der Oberfläche der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 zugestellt ist, können Textilbehandlungseinrichtungen vorgesehen sein, welche das Textil 60 auf der Halteeinrichtung 30 behandeln, vorzugsweise bedrucken. Nach der Fig. 1 ist eine erste Farbstation 51, ein Zwischentrockner 52 und eine Farbdruckstation 53 vorgesehen, welche das Druckbild (printout) 61 auf der Oberfläche des Textils 60 vorsehen. Hinter dem Behandlungsbereich I kann die Andrückeinrichtung 40 beziehungsweise das Profilband oder die Andrückelemente 41, 42 von der Oberfläche der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 vorzugsweise nach oben, insbesondere über Umlenkrollen, abgeführt werden.How out Fig. 1 As can be seen, a textile 60 is provided on a holding device 30, with part of the textile 60 - here a T-shirt - overlapping over the holding device 20 and lying directly on the conveyor device 20, in particular the circulating conveyor 21. The at least one pressure element 41 can be provided directly on the holding device 30 or to the right or left of the holding device 30 directly on the conveyor 20 or the circulating conveyor 21, the textile between the at least one pressure element 41 and the holding device 30 and / or the conveyor 20 or the circulating conveyor 21 can be provided. This allows the textile to be braced between the respective surfaces of the devices and elements. Furthermore, the pressing unit 40 can have at least one connecting element 44 which connects a first pressing element 41 and a second pressing element 42 to one another. The two pressure elements 41, 42 are here preferably guided parallel to one another and fed to the conveyor device 20 or the circulating conveyor 21 of the treatment device 10. The connecting elements 44 can form at least one opening 45 with the pressing elements 41 and 42, which opening corresponds approximately to the shape of the holding device 30. A profile strip is particularly preferably provided which has the openings 45. The pressure elements 41, 42 of the surface of the conveying device 20 or the circulating conveyor 21 can be delivered via the rollers 43. The pressing elements 41, 42 of the pressing device 40 can in particular be deliverable to an area of the conveying device 20 or the circulating conveyor 21 which lies in the conveying direction behind an area in which the holding device 30 can be equipped with a textile 60. In the area, here marked with I, in which the pressure elements 41, 42 or the profile band of the pressure unit 40 is fed to the surface of the conveyor 20 or the circulating conveyor 21, textile treatment devices can be provided which treat the textile 60 on the holding device 30, preferably to print. After Fig. 1 a first color station 51, an intermediate dryer 52 and a color printing station 53 are provided, which provide the printout 61 on the surface of the textile 60. Behind the treatment area I, the pressure device 40 or the profile band or the pressure elements 41, 42 can be carried away from the surface of the conveyor device 20 or the circulating conveyor 21, preferably upwards, in particular via deflection rollers.

Die Öffnungen 45 können hierbei den Halteeinrichtungen 30 so zugestellt werden, dass im Inneren der Öffnungen 45 ein Druckbereich für das jeweilige Textil 60 unverdeckt vorliegt. Hinter dem Textilbearbeitungsbereich I kann eine weitere Umlenkrolle 22 vorgesehen sein, über welche der Umlaufförderer 21 einem ersten Bereich der Fördereinrichtung beziehungsweise dem Umlaufförderer 21 rückgestellt werden kann, um mit neuem Textil 60 bestückt zu werden. Hinter dem Textilbehandlungsbereich I können auch weitere Einrichtungen zum Bearbeiten oder Behandeln von Textil, beispielsweise eine Verpackungsstation oder Imprägnierstation vorgesehen sein.The openings 45 can be fed to the holding devices 30 in such a way that a printing area for the respective textile 60 is present in the interior of the openings 45, uncovered. A further deflection roller 22 can be provided behind the textile processing area I, via which the circulating conveyor 21 can be reset to a first area of the conveyor device or the circulating conveyor 21 in order to be equipped with new textile 60. Behind the textile treatment area I, further devices for processing or treating textiles, for example a packaging station or an impregnation station, can also be provided.

Die Form der Öffnung 45 entspricht in etwa der Form der Halteeinrichtung 30. Die Andrückelemente 41, 42, welche vorzugsweise als Endlosfördermittel ausgebildet sind, können über einen eigenen Antrieb, welcher beispielsweise im Bereich einer der Umlenkrollen 43 vorgesehen ist, angetrieben werden. Alternativ oder ergänzend hierzu kann die Andrückeinrichtung vorzugsweise durch Kontakt von mindestens einem Andrückelement mit der Halteeinrichtung 30 oder der Fördereinrichtung 20, insbesondere dem Umlaufförderer 21, insbesondere durch Kontaktreibung, also passiv, durch die Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 angetrieben werden. Die Andrückeinrichtung 40 kann demnach insbesondere durch eine abrollende Kontaktierung mit der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 angetrieben werden. Der Abstand der Öffnungen 45 zu einer weiteren Öffnung 45 ist vorzugsweise dem Abstand einzelner Halteeinrichtungen 30 auf der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 entsprechend.The shape of the opening 45 roughly corresponds to the shape of the holding device 30. The pressure elements 41, 42, which are preferably designed as endless conveying means, can be driven via their own drive, which is provided, for example, in the area of one of the deflection rollers 43. Alternatively or in addition to this, the pressing device can preferably be driven by contact of at least one pressing element with the holding device 30 or the conveying device 20, in particular the circulating conveyor 21, in particular by contact friction, i.e. passively, by the conveying device 20 or the circulating conveyor 21. The pressing device 40 can accordingly be driven in particular by a rolling contact with the conveying device 20 or the circulating conveyor 21. The distance between the openings 45 and a further opening 45 is preferably corresponding to the spacing of individual holding devices 30 on the conveyor device 20 or the circulating conveyor 21.

Hierdurch kann die Position der mindestens einen Öffnung 45 gegenüber der Halteeinrichtung 30 besonders ortsgenau vorgesehen werden.In this way, the position of the at least one opening 45 relative to the holding device 30 can be provided with a particularly precise location.

Vorzugsweise sind mindestens vier Umlenkrollen 43 an der Andrückeinrichtung 40 vorgesehen, so dass zum einen eine Parallelführung von mindestens zwei Andrückelementen 41, 42 oder des Profilbands in Förderrichtung gleichförmig zu den Halteeinrichtungen 30 auf dem Umlaufförderer 21 ermöglicht ist. Zum anderen kann oberhalb der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21, vorzugsweise oberhalb der Textilbearbeitungsstationen 51 bis 53 eine Rückführung der Andrückelemente 41, 42 zu einem Bereich vor dem Textilbearbeitungsbereich I in etwa parallel, jedoch in entgegengesetzter Richtung zur Förderrichtung der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 ermöglicht sein.At least four deflection rollers 43 are preferably provided on the pressure device 40, so that, on the one hand, parallel guidance of at least two pressure elements 41, 42 or the profile belt in the conveying direction is uniform to the holding devices 30 on the circulating conveyor 21. On the other hand, above the conveyor 20 or the circulating conveyor 21, preferably above the textile processing stations 51 to 53, a return of the pressure elements 41, 42 to an area in front of the textile processing area I approximately parallel, but in the opposite direction to the conveying direction of the conveyor 20 or the circulating conveyor 21 be made possible.

Durch einen Abstand der unteren Umlenkrollen 43 zu der Fördereinrichtung 20 beziehungsweise dem Umlaufförderer 21 kann ein Anpressdruck des Andrückelements 41, 42 beziehungsweise des Profilbandes auf der Fördereinrichtung 20, insbesondere dem Förderband 21 einstellbar sein. Somit kann, einem Schleifkontakt zwischen Andrückelement 41, 42 und der Fördereinheit 20, insbesondere das Förderband 21, durch einen hinreichend großen Anpressdruck vorgebeugt sein. Durch das Unterbinden eines Schleifkontakts kann die Positionierung der mindestens einen Öffnung 45 gegenüber der Halteeinrichtung 30 festlegbar sein.A contact pressure of the pressure element 41, 42 or the profile belt on the conveyor 20, in particular the conveyor belt 21, can be set by a distance between the lower deflection rollers 43 and the conveyor 20 or the circulating conveyor 21. Thus, a sliding contact between the pressure element 41, 42 and the conveyor unit 20, in particular the conveyor belt 21, can be prevented by a sufficiently high contact pressure. By suppressing a sliding contact, the positioning of the at least one opening 45 relative to the holding device 30 can be fixed.

Besonders bevorzugt sind die Umlenkrollen 43 vertikal einstellbar, wodurch der Anpressdruck einstellbar ist. Weiterhin können sowohl die oberen Umlenkrollen 43 als auch die unteren kontaktierenden Umlenkrollen 43 horizontal in etwa parallel zur Förderrichtung des Umlaufförderers 21 verstellbar sein, wodurch der kontaktierende Bereich I der Länge nach entlang der Fördereinheit 21 veränderbar ist. Hierdurch kann die Länge des Bearbeitungsbereichs I und somit des Textilbehandlungsbereichs bedarfsgerecht auf der Fördereinrichtung 20 beziehungsweise den Umlaufförderer 21 eingestellt werden.The deflection rollers 43 are particularly preferably vertically adjustable, whereby the contact pressure can be adjusted. Furthermore, both the upper deflecting rollers 43 and the lower contacting deflecting rollers 43 can be horizontally adjustable approximately parallel to the conveying direction of the circulating conveyor 21, as a result of which the contacting area I can be changed lengthways along the conveying unit 21. As a result, the length of the processing area I and thus of the textile treatment area can be adjusted on the conveyor device 20 or the circulating conveyor 21 as required.
