Description

Bahnen aus Textilgewebe, Strickwerk und aus textilartigem Werkstoff wie sie etwa unter dem Begriff "non woven" bekannt sind, werden in der Regel nach Abschluß ihrer substantiellen Fertigstellung durch eine Legevorrichtung in Faltenstapel gelegt und in dieser Form der weiteren Verarbeitung zugeführt. Da jedoch die Kapazität der Herstellungsmaschinen solcher Textilbahnen wie Strickmaschinen und dergleichen begrenzt ist, haben auch die auf solche Weise gefertigten Textilbahnen nur eine begrenzte Länge. Daher sind die vornehmlich thermischen Behandlungszyklen, aber auch chemische Behandlungsvorgänge nur für kurze Zeitspannen auszuführen, oder man muß die Anlage stillsetzen, um eine neue Textilbahn einführen zu können. Auf diese Weise werden nicht nur die Bearbeitungszeit verlängert und die Herstellungskosten vergrößert, sondern es kann auch durch unkontrolliert lange Einwirkungen von Bearbeitungsmedien zu teils erheblichen Qualitätsminderungen, oftmals zu Ausschuß kommen.Sheets of textile fabric, knitting and of textile-like material, such as are known for example under the term "non-woven", are usually placed in a stack of folds after completion of their substantial completion by a laying device and fed to this form for further processing. However, since the capacity of the production machines of such textile webs such as knitting machines and the like is limited, the textile webs produced in this way also have a limited length. Therefore, the primarily thermal treatment cycles, but also chemical treatment processes can only be carried out for short periods, or the system must be shut down in order to be able to introduce a new textile web. In this way, not only is the processing time extended and the manufacturing costs increased, but uncontrolledly long exposure to processing media can sometimes lead to considerable quality reductions, often to rejects.

Die Erfindung geht aus von dem eingangs definierten Verfahren und verfolgt die Aufgabe, dieses Verfahren in solcher Weise weiterzubilden, daß ein Umsetzen oder Neueinführen von Textilbahnen während der Funktionsdauer einer verfahrenstechnischen Behandlung weitgehend vermieden wird.The invention is based on the method defined at the outset and pursues the task of developing this method in such a way that the implementation or reintroduction of textile webs is largely avoided during the functional period of a process engineering treatment.

Zur Lösung dieser Aufgabe werden erfindungsgemäß mehrere kürzere Textilbahnen mit ihren Enden zu einer einzigen langen Textilbahn verbunden, und daraufhin wird die lange Textilbahn in kontinuierlichem Durchlauf einer verfahrenstechnischen Behandlung unterworfen und anschließend in Einheiten der kürzeren Textilbahnen gefaltet und in Stapeln abgelegt.To achieve this object, several shorter textile webs are connected according to the invention with their ends to form a single long textile web, and then the long textile web is subjected to a process-related treatment in a continuous pass and then folded in units of the shorter textile webs and stored in stacks.

Im Prinzip können die kurzen Textilbahnen unmittelbar nach Fertigstellen der einzelnen Faltenstapel voneinander getrennt werden, aber hierzu besteht keine Notwendigkeit, d.h. man kann die noch zusammenhängenden Faltenstapel weiter fördern und gegebenenfalls einer weiteren kontinuierlichen oder schrittweisen Behandlung unterziehen.In principle, the short textile webs can be separated from one another immediately after the individual fold stacks have been completed, but there is no need for this, i.e. the stack of folds still connected can be conveyed further and optionally subjected to a further continuous or step-wise treatment.

Auf diese Weise wird eine eingesetzte Textilbahn bis zum Auslauf ihres Endes durch die ganze Anlage ohne jeden Stillstand hindurchgefördert. Der Werkstoff kann daher weder durch Überhitzen noch durch andere überlange Einwirkung eines Mediums eine Änderung erfahren.In this way, an inserted textile web is conveyed through the whole system without any standstill until its end. The material can therefore not change due to overheating or other excessive exposure to a medium.

Nach einer Weiterbildung der Erfindung werden an oder mit fester Zuordnung zu den Verbindungsstellen zwischen benachbarten Kurzbahnen berührungslos abstastbare Signalelemente eingearbeitet, deren Vorhandensein an einer vorgegebenen Durchlaufstelle der Langtextilbahn abgetastet und für Steuerungszwecke zum Legen der Textilbahn und Weiterfördern der so gebildeteten Faltenstapel herangezogen wird. Auf diese Weise gehen die Steuerimpulse grundsätzlich von der zu bearbeitenden Textilbahn aus, insbesondere aus dem Bereich der Verbindungsstellen zwischen benachbarten Kurzbahnen. Dabei ist es zwar erwünscht, aber nicht notwendig, daß diese Kurzbahnen gleiche Länge haben und auch die Signalelemente immer in bestimmter Weise der Verbindungsstelle zugeordnet sind. Um einen vollständig automatischen Betrieb zu ermöglichen, sollte aber der Abstand zwischen der Taststelle für das Signalelement und der Legevorrichtung vermessen und auf eine ganze Mehrzahl von Faltenbreiten beziehungsweise Legelängen abgestimmt werden.According to a further development of the invention, contactlessly scannable signal elements are incorporated on or with a fixed assignment to the connection points between adjacent short paths, the presence of which is sensed at a predetermined passage point of the long textile path and used for control purposes for laying the textile path and further conveying the fold stacks thus formed. In this way, the control impulses generally originate from the textile web to be processed, in particular from the area of the connection points between adjacent short webs. It is desirable, but not necessary, that these short paths have the same length and that the signal elements are always assigned to the connection point in a certain way. In order to enable fully automatic operation, however, the distance between the touch point for the signal element and the laying device should be measured and matched to a large number of pleat widths or laying lengths.

Dies ermöglicht auch eine bestimmte Einordnung des Signalelementes in der Bahn zwischen benachbarten Warenstapeln.This also enables the signal element to be arranged in a certain way in the web between adjacent stacks of goods.

Zweckmäßigerweise wird mit dem Legen eines neuen Stapels begonnen, wenn die Verbindungsstelle mit dem Signalelement so weit über den Legebereich hinausgelangt ist, daß sie jeweils mit Abstand zwischen zwei benachbarte Faltenstapel zu liegen kommt. An dieser Stelle läßt sich dann die Bahn nach Bedarf durchschneiden, um die einzelnen im übrigen unversehrten Kurzbahnen unterschiedlichen Weiterbehandlungen zuzuführen.It is useful to start laying a new stack when the connection point with the signal element has reached so far beyond the laying area that it comes to lie at a distance between two adjacent fold stacks. At this point, the web can then be cut as required in order to supply the individual, otherwise undamaged, short webs to different further treatments.

Die Erfindung betrifft ferner eine Vorrichtung zur im kontinuierlichen Durchlauf erfolgenden verfahrenstechnischen Behandlung von Textilbahnen in Stapeln, wobei mehrere kürzere Textilbahnen mit ihren Enden zu einer einzigen langen Textilbahn verbunden werden und daraufhin die lange Textilbahn mit kontinuierlichem Durchlauf in Einheiten der kürzeren Textilbahnen gefaltet und in Stapeln abgelegt wird, insbesondere nach einem vorgeschilderten Verfahren, wobei dicht an der Textilbahn mit vorgegebenem Abstand vor der Legevorrichtung ein Detektor zum Abtasten eines in wenigstens einer Verbindungsstelle oder mit bestimmter Zuordnung zu einer Verbindungsstelle in die Textilbahn eingearbeiteten Signalelementes für die Steuerung einer Legevorrichtung zur Bildung einzelner Faltenstapel und deren Abtransport in Zuordnung zu benachbarten Faltenstapeln angebracht ist.The invention further relates to a device for the continuous process-related treatment of textile webs in stacks, wherein several shorter textile webs are connected at their ends to form a single long textile web and then the long textile web is folded in units of the shorter textile webs and stored in stacks is, in particular according to a method described, close to the textile web with a predetermined distance in front of the laying device, a detector for scanning a signal element incorporated in at least one connection point or with a specific assignment to a connection point in the textile web for controlling a laying device to form individual fold stacks and whose removal is arranged in association with neighboring stacks of folds.

Die vom Detektor ausgelöste Steuerung kann dabei einen Programmspeicher mit einer Wähleinrichtung zum Vorwählen eines Arbeitsprogramms entsprechend der Beschaffenheit, der Abmessungen und der Behandlung der jeweiligen Textilbahn sowie des Transportweg-Abstandes zwischen Detektor und Legevorrichtung aufweisen.The controller triggered by the detector can have a program memory with a selection device for preselecting a work program in accordance with the nature, dimensions and treatment of the respective textile web and the distance of the transport path between the detector and the laying device.

Weitere Fortbildungen und Vorteile der Erfindung sind in den Ansprüchen festgehalten und der Beschreibung des Ausführungsbeispieles zu entnehmen, das jetzt anhand der Zeichnungen näher erläutert werden soll.Further developments and advantages of the invention are set out in the claims and can be found in the description of the exemplary embodiment, which will now be explained in more detail with reference to the drawings.

Nach Fig.1 wird aus einem Aufgabelager (1) eine meist schlauchförmige Textilbahn (2) abgezogen und durch einen Dämpfkalander (3) mit Kalanderwalzen (4) hindurch einer Kühlzone (5) und dann einer Legevorrichtung (6) zugeführt, die einzelne Faltenstapel (7) bildet, die in Zwischenabständen über eine Rollenbahn (8) weitergefördert werden. Die (lange) Textilbahn (2) setzt sich zusammen aus einzelnen kurzen Textilbahnen (21,22,23,24, usw).Show it:
Fig. 1
a schematic side view of a device for steaming, cooling or relaxing and then laying a textile web and the
Fig. 2-7
Partial views from Fig.1 in different operating positions
According to Fig. 1, a mostly tubular textile web (2) is drawn off from a feed store (1) and fed through a steaming calender (3) with calender rollers (4) to a cooling zone (5) and then to a laying device (6), which feeds individual fold stacks ( 7) forms, which are conveyed at intervals between a roller conveyor (8). The (long) textile web (2) is composed of individual short textile webs (21, 22, 23, 24, etc.).

Die Legevorrichtung (6) weist einen höhenverstellbaren Legeschlitten (11) mit Führungswalzen (12) und Bügelrollen (13) auf, sowie einen Legetisch (14) mit einem über diesen geführten Förderband (15).The laying device (6) has a height-adjustable laying carriage (11) with guide rollers (12) and bow rollers (13), and a laying table (14) with a conveyor belt (15) guided over it.

Der Legetisch (14) ist zwischen der mit vollen Linien ausgezogenen Vorwärtsstellung und mit der Strichpunktlinien eingezeichneten Rückwärtsstellung (16) hin- und hergehend verfahrbar und legt dabei einen der Faltenlänge entsprechenden Legehub h zurück. Dieser Legetisch (14) ist an eine endlose Kette angeschlossen, die zwischen zwei Umlenkrollen parallel zur Tischführung gespannt ist und ein Eingriffsteil wie einen Kulissenstein trägt, der in eine am Legeschlitten (11) vorgesehene, quer zur Schlittenführung verlaufende Kulissenführung greift. Der nicht gezeigte Antrieb des Transportbandes (15) wird einerseites gesteuert durch einen am Maschinengestell angebrachten Tisch-Endschalter (18), der von dem am Legetisch (14) angebrachten Anschlag (20) betätigt wird, und andererseits mittels eines am Legetisch (14) angebrachten Nockenschalters (28) durch in Abständen des Legehubes (h) am Förderband (15) selbst vorgesehene Nocken (29).The laying table (14) can be moved back and forth between the forward position drawn with full lines and the backward position (16) drawn in with the dash-dot lines and thereby covers a laying stroke h corresponding to the length of the folds. This laying table (14) is connected to an endless chain, which is tensioned between two deflection rollers parallel to the table guide and carries an engagement part such as a sliding block, which extends into a sliding guide provided on the laying slide (11) and runs transversely to the slide guide takes hold. The drive of the conveyor belt (15), not shown, is controlled on the one hand by a table limit switch (18) attached to the machine frame, which is actuated by the stop (20) attached to the laying table (14), and on the other hand by means of a attached to the laying table (14) Cam switch (28) by means of cams (29) provided on the conveyor belt (15) at intervals of the laying stroke (h).

Gestellfest ist wiederum das der Rollenbahn vorgeschaltete Abförderband (30) angeordnet, das zum Abfördervorgang über den am Maschinengestell angebrachten Tisch-Endschalter (17), mittels des am Legetisch (14) angebrachten Anschlages (19) eingeschaltet und in Bewegung gesetzt und über einen am Legetisch (14) angebrachten Nockenschalter (28) durch in Abständen des Legehubes h am Förderband (15) selbst vorgesehene Nocken (29) zum Stillstand gebracht wird.The removal conveyor belt (30) upstream of the roller conveyor is arranged in a frame-fixed manner, which is switched on and set in motion for the removal operation via the table limit switch (17) attached to the machine frame, by means of the stop (19) attached to the laying table (14), and via one on the laying table (14) attached cam switch (28) is brought to a standstill by cams (29) provided at intervals of the laying stroke h on the conveyor belt (15).

Die Bahnenden (31) der Kurztextilbahnen (21-24) sind in den Verbindungsstellen (37) fest miteinander verbunden, insbesondere quer zur Bahnrichtung vernäht. In der Naht oder wenigstens dicht an der Verbindungsstelle ist ein hier durch eine Verdickung der Bahn angedeudetes Signalelement (32) eingearbeitet, beispielsweise ein metallischer Faden. Da die Textilbahn (2) dicht an einem Detektor (33), beispielsweise einem UV-Detektor vorbeigeführt ist, gibt dieser stets dann ein Auslösesignal an die Steuerung (34).The web ends (31) of the short textile webs (21-24) are firmly connected to one another in the connection points (37), in particular sewn transversely to the web direction. A signal element (32), indicated here by a thickening of the web, is incorporated in the seam or at least close to the connection point, for example a metallic thread. Since the textile web (2) passes close to a detector (33), for example a UV detector, the latter always sends a trigger signal to the controller (34).

Sofern die Faltenstapel gleiche Höhe haben und jeweils einer einzigen Kurzbahn entsprechen sollen, erfordert dies gleiche Länge der Kurzbahnen (21-24). Zudem muß die Führungslänge zwischen dem Detektor (33) und einer Stelle im Bereich der Legevorrichtung einem ganzen Vielfachen der Faltenlänge bzw. des Legehubes (h) entsprechen. In der Regel reicht ein einmaliges Ausmessen, es können allerdings auch Verstellmittel zur Anpassung der wirklichen Führungslänge an den Legehub vorgesehen sein.If the fold stacks are of the same height and each correspond to a single short path, this requires the same length of the short paths (21-24). In addition, the guide length between the detector (33) and a point in the area of the laying device must correspond to a whole multiple of the fold length or the laying stroke (h). As a rule, a single measurement is sufficient, but adjustment means can also be provided to adapt the actual guide length to the laying stroke.

Wie die Figuren 1 und 2 erkennen lassen, entspricht diese Wegstrecke etwa der halben Länge der Kurztextilbahn (22), und der zweite Signalgeber (321) hängt in einer Bahnschleife (36) zwischen den beiden Faltenstapeln (7) und (71), der vorangehende Signalgeber (322) zwischen den Faltenstapeln (71) und (72).As can be seen in FIGS. 1 and 2, this distance corresponds to approximately half the length of the short textile web (22), and the second signal transmitter (321) hangs in a web loop (36) between the two fold stacks (7) and (71), the preceding one Signal generator (322) between the fold stacks (71) and (72).

Damit nach der jetzt erfolgten Impulsgabe der Stapel (7) noch auf die gleiche Höhe wie die anderen Stapel (71) und (72) gebracht werden kann, muß die Textilbahn noch um eine aus dem Aufgabespeicher entnehmbare einfache oder mehrfache ganze Faltenlänge weitergefördert und abgelegt werden. Wenn die Verbindungsstelle (37) mit dem Signalelement (32) sich dem Stapel (7) gemäß Fig.3 bis auf ein bis zwei Faltenlängen h genähert hat, so wird bei Betätigen des hinteren Tischschalters (17) eine Folgeschaltung ausgelöst und dadurch das Abförderband (30) mit der gleichen Geschwindigkeit wie der Legetisch (14) in Bewegung gesetzt. Wird nun entsprechend Fig.5 in einer Anschlußstellung zum Abförderband (30) noch der vordere Tischschalter (18) betätigt, so bleibt der Legetisch (14) in dieser rechten Endstellung stehen. Gleichzeitig wird das auf dem Legetisch (14) befindliche Förderband (15) mit der gleichen Geschwindigkeit wie das Abförderband (30) in Bewegung gesetzt, wobei die Nocke (29) vom Bandschalter (28) abläuft, der Faltenstapel (7) auf das Abförderband (30) überführt und der Stapel (71) vom Abförderband auf die Rollenbahn (8) geschoben wird und den Stapel (72) weiterschiebt.In order for the stack (7) to be brought to the same height as the other stacks (71) and (72) after the momentum has now been given, the textile web has to be conveyed and deposited by a single or multiple whole fold length that can be removed from the feed store . If the connection point (37) with the signal element (32) has approached the stack (7) according to FIG. 3 to one or two fold lengths h, a sequential circuit is triggered when the rear table switch (17) is actuated, and the conveyor belt ( 30) set in motion at the same speed as the laying table (14). If, according to FIG. 5, the front table switch (18) is still actuated in a connection position to the conveyor belt (30), the laying table (14) remains in this right end position. At the same time, the conveyor belt (15) on the laying table (14) is set in motion at the same speed as the conveyor belt (30), the cam (29) running off the belt switch (28), the stack of folds (7) on the conveyor belt ( 30) transferred and the stack (71) is pushed from the conveyor belt onto the roller conveyor (8) and pushes the stack (72) onward.

Sobald der Bandschalter (28), nachdem die Nocke (29) abgelaufen ist, von der nächstfolgenden Nocke betätigt wird, kommt das Abförderband (30) zum Stillstand und der Legeschlitten (11) fährt in seine untere Ausgangslage. Das Förderband (15) läuft zur Bildung der Schleife (36) noch um eine Lagelänge weiter. Wird der Bandschalter (28) von der übernächstfolgenden Nocke betätigt, so bleibt das Förderband (15) stehen und der Legetisch (14) beginnt wieder hin- und herzufahren.As soon as the belt switch (28) is actuated by the next cam after the cam (29) has expired, the conveyor belt (30) comes to a standstill and the laying carriage (11) moves to its lower starting position. The conveyor belt (15) continues to form a loop for forming the loop (36). If the belt switch (28) is actuated by the next cam, the conveyor belt (15) stops and the laying table (14) begins to move back and forth.

Das Signalelement kann selbststrahlungsaktiv sein, es genügt aber die Eigenschaft der Ertastbarkeit durch irgendeinen der bekannten Detektoren.The signal element can be self-radiation active, but the property of tactility by any of the known detectors is sufficient.

Der nicht eingezeichnete Programmspeicher kann mit anderen Steuereinheiten in der Steuerung (34) zusammengefaßt sein, die ihren Auslöseimpuls vom Detektor (33) erhält. Auch der Programmwähler muß jede gleichende Ausbildung und Anordnung erfahren.The program memory (not shown) can be combined with other control units in the controller (34), which receives its trigger pulse from the detector (33). The program selector must also experience every similar training and arrangement.

Auf diese Weise können nahezu beliebig viele Kurzbahnen hintereinandergeschaltet, einer wie auch immer gearteten Behandlung unterworfen und anschließend abgetafelt werden, ohne daß Teile einer Kurzbahn einem anderen Faltenstapel zugeführt werden. Daher lassen sich grundsätzlich auch Textilbahnen hintereinanderschalten, die in mancherlei Hinsicht unterschiedlich beschaffen sind, solange sie durch die vorgesehene Behandlung nicht nachteilig verändert werden. Die einzelnen Faltenstapel können bis zur Konfektionierung zusammengeschlossen bleiben oder nach Bedarf an der Trennstelle bzw. einer Naht wieder voneinander gelöst werden.In this way, almost any number of short paths can be connected in series, subjected to any kind of treatment and then paneled without parts of a short path being fed to another fold stack. Therefore, in principle, textile webs can also be connected in series, which have different properties in many respects, as long as they are not adversely changed by the intended treatment. The individual fold stacks can be kept together until ready for assembly or can be detached from one another at the point of separation or a seam.

  3. The method as claimed in claim 2, characterized in that the marker element arranged at the connection point is stretched out like a thread or wire and is arranged in the plane of the textile web transversely in relation to the longitudinal extent thereof.
  4. The method as claimed in claim 2 or claim 3, characterized in that a radiation active marker element is incorporated at the point of connection or respectively an adjacent part of the textile web.
  5. The method as claimed in any one of the claims 2 through 4, characterized in that at least one metallic marker element is incorporated at the point of connection or respectively an adjacent part of the textile web.
  6. The method as claimed in any one of the claims 2 through 5, characterized in that the passage of the marker element through rays of invisible light is detected.
  7. The method as claimed in claim 6, characterized in that the passage of the marker element is detected by means of a detector for ultraviolet radiation.
  8. The method as claimed in claim 7, characterized in that the distance between the point of detection for the marker element and the folding device is measured and matched to whole number of fold widths or, respectively, fold lengths and in that folding to form a new stack is only commenced in each case when the connection point with the marker element has arrived at a predetermined point on the folding device.
  9. The method as claimed in claim 8, characterized in that folding to form a new stack is only commenced when the point of connection with the marker element has moved so far past the zone of folding that it respectively assumes a position between two adjacent stacks of folds.
  10. The method as claimed in any one of the claims 1 through 9, characterized in that a stack of folds is formed on a conveyor belt constituting the folding table and adapted to be moved through the distance of one folding operation or the length of one fold, which conveyor belt is then moved into a connection position close to a removal conveyor belt and in that following this the folded stack is transferred from the conveyor belt to the removal conveyor belt.
  11. The method as claimed in claim 10, characterized in that for the transfer of a stack of folds from the conveyor belt to the removal conveyor belt both belts are simultaneously operated at the same speed.
  12. The method as claimed in any one of the claims 8 through 11, characterized in that the length of connection parts left between adjacent stacks of folds is so selected that they still sag somewhat at the maximum distance between the two belts.
  13. An apparatus for an industrial treatment process performed with continuous motion, such as thermal treatment cycles or chemical treatment procedures performed on textile webs, characterized in that a plurality of short textile webs are connected together at their ends to constitute a single long textile web (2) and following this the long textile web is folded continuously as units of the short textile webs and is deposited in stacks, more particularly in accordance with a previously described method and in that close to the textile web (2) with a predetermined distance in front of the folding device (6) a detector (33) is arranged for the detection a marker element (32) incorporated at one connection point at least in the textile web for the control of a folding device (6) for the formation of individual stacks of folds (7, 71...) and the conveyance thereof to the adjacent stacks of folds (71, 72, 73...).
  14. An apparatus as claimed in claim 13, characterized in that the control caused by the detector (33) has a program memory with a selection device for the preselection of an operating program in accordance with the nature, of the dimensions and of the treatment of the respective textile web (2) and of the conveyance path distance between the detector (33) and the folding device (6).
  15. An apparatus as claimed in claim 13 or in claim 14, characterized in that the folding device (6) possesses a folding table (14) able to be reciprocated along a folding stroke h and having a conveyor belt (15) and is able to be moved with the latter as far as a position close to a connection position for an adjoining removal conveyor belt (30).
  16. An apparatus as claimed in claim 15, characterized by control means (34, 17, 18 and 28) for switching on the drives of the conveyor belt (15) and the removal conveyor belt (30) for a short time in the connection position for the transfer of a completed stack of folds (7) onto the removal conveyor belt (30).
  17. An apparatus as claimed in any one of the claims 13 through 16, characterized in that limit switches (17 and 18) are incorporated in a sequence control means for the conveyor belt (15) in order to detect the terminal positions of the conveyor belt.
  18. An apparatus as claimed in any one of the claims 13 through 17, characterized in that for the control of the two conveyor belts (15 and 30) and of the folding table (14) cams (20) for actuating a cam driven switch (28) are provided on the conveyor belt itself or on a machine part, circulating synchronously with it, with predetermined distances between them.
  19. An apparatus as claimed in either of the claims 17 and 18, characterized in that the limit switches (17 and 18) for the folding table (14) and the cam driven switch (28) to be operated by the cams (29) are so incorporated in a sequence control system that the functions relating to the removal of a stack (7 and 71) of folds are only performed after a predetermined number of folding operations.
