Abstract

The externally held, adjustable width spreader for tubular material (1) present in a flat state is provided with two spreading and guiding units (2, 3) which are to be arranged next to one another in the interior of the tubular material. The spreading and guide units are each provided with an endless transporting belt (4) which extends along their outer guide faces and is exposed there. The transporting belts (4) and in releasable operating engagement with feed rollers (8, 9, 10, 11) disposed on the exterior of the tubular material (1) passing through. To be able to unimpededly change the width of the spreader externally during the passage of tubular material (1), each one of the two guide units (2, 3) is held in its position by means of externally engaging support rollers (12-15) whose axes of rotation (16) are perpendicular to the direction of passage of the tubular material (1) and which are in releasable engagement with counterrollers (17-20) which are rotatably mounted in the guide units (2, 3) and are supported thereby. To vary the spreading width of the spreader, the feed and support rollers (8-11, 12-15) associated with the one guide unit (2) are mounted in a carriage (21) so as to be jointly displaceable in the spreading direction (B).

Description

Die Erfindung betrifft einen von aussen gehaltener, verstellbarer Breithalter für in flachem Zustand vorliegende Schlauchware, welche in Durchlaufrichtung über den Breithalter bewegt und durch diesen in einer zweiten, senkrecht zur ersten Richtung verlaufenden Spreizrichtung gespreizt wird, und mit mindestens zwei im Inneren der Schlauchware seitlich nebeneinander anzuordnenden Spreizeinheiten, welche mit mindestens je einem über einen Teil ihres Umfanges längs der Aussenseite der zugeordneten Spreizeinheit verlaufenden endlosen Transportriemen versehen sind, welche mit ausserhalb der Bewegungsbahn der durchlaufenden Schlauchware sich befindenden Rollen lösbar in Eingriff stehen, wobei die Spreizeinheiten durch zusammenwirken von in ihr drehbar gelagerten Gegenrollen mit den ausserhalb der Bewegungsbahn der Schlauchware angeordneten Rollen in Bewegungsrichtung der Schlauchware festgehalten werden.The invention relates to an externally held, adjustable spreader for tubular goods present in a flat state, which is moved in the direction of passage over the spreader and is spread by the spreader in a second, perpendicular to the first direction, and with at least two inside the tubular goods side by side to be arranged spreading units, which are each provided with at least one endless conveyor belt running over part of their circumference along the outside of the assigned spreading unit, which are releasably engaged with rollers located outside the path of movement of the tubular material passing through, the spreading units being rotatable by interaction of them stored counter rollers with the rollers arranged outside the path of movement of the tubular goods are held in the direction of movement of the tubular goods.

Aus der DE-A-2 823 978 ist ein im Innern einer Schlauchware anzuordnender Breithalter in Form eines flachen, durch Teleskoprohre weitenverstellbaren Rahmens bekannt, bei dem die Teleskoprohre an ihren äusseren Enden über Kopfteile mit zwei spiegelbildlich zueinander angeordneten Längsstegen des Rahmens miteinander verbunden sind.DE-A-2 823 978 discloses a spreader to be arranged in the interior of a tubular material in the form of a flat frame which is adjustable in width by means of telescopic tubes, in which the telescopic tubes are connected to one another at their outer ends via head parts with two longitudinal webs of the frame arranged in mirror image to one another.

Dieser bereits bekannte Breithalter weist jedoch den gravierenden Nachteil auf, dass er nur innerhalb relativ enger Grenzen über die Teleskoprohre in seiner Breite verstellbar ist. Ferner ist ein Verstellen des Breithalters bei durchlaufender Schlauchware, zum Beispiel bei aneinandergehängter Schlauchware unterschiedlicher Breite, nicht möglich. Ändert die Breite der durchlaufenden Schlauchware, dann muss deren Vorschub unterbrochen, die Ware unterschiedlicher Breite voneinander getrennt, und der Breithalter in seiner Breite entsprechend verstellt, oder wenn sein Verstellbereich dazu nicht genügt, ausgewechselt werden. Dies stellt eine sehr unerwünschte und umständliche Unterbrechung des möglichst kontinuierlich gewünschten Arbeitsablaufes dar.However, this already known spreader has the serious disadvantage that the width of the telescopic tubes can only be adjusted within relatively narrow limits. Furthermore, it is not possible to adjust the spreader when the tubular goods run through, for example when the tubular goods are of different widths connected to one another. If the width of the continuous tubular goods changes, then their feed must be interrupted, the goods of different widths must be separated from one another, and the width of the spreader adjusted accordingly, or if its adjustment range is not sufficient, it must be replaced. This represents a very undesirable and cumbersome interruption of the workflow that is desired as continuously as possible.

Aufgabe der vorliegenden Erfindung ist die Schaffung eines Breithalters, welcher die vorerwähnten Nachteile der bisher bekannten Breithalter nicht aufweist, das heisst bei dem der Breitenverstellbereich beliebig wählbar ist und bei dem eine Verstellung der Breite selbst bei eingespannter und durchlaufender Schlauchware von aussen her möglich ist.The object of the present invention is to provide a spreader which does not have the aforementioned disadvantages of the previously known spreader, that is to say in which the width adjustment range can be selected as desired and in which an adjustment of the width is possible from the outside even when the tubular goods are clamped and run through.

Diese Aufgabe wird bei einem Breithalter der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass jede der Spreizeinheiten einzeln mittels ausserhalb der Bewegungsbahn der Schlauchware angeordneten Abstützrollen, deren Drehachsen in Spreizrichtung der Schlauchware verlaufen, und die mit den in den Spreizeinheiten drehbar gelagerten Gegenrollen lösbar in Eingriff stehen, in ihrer Lage festgehalten wir, dass die Drehachsen der den Vorschub bewirkenden Rollen ebenfalls in Spreizrichtung verlaufen, und dass mindestens die der einen Führungseinheit zugeordneten Vorschub- und Abstützrollen zur Veränderung der Spreizbreite des Breithalters gemeinsam in Spreizrichtung verstellbar angeordnet sind.This object is achieved according to the invention in a spreader of the type mentioned at the outset in that each of the spreading units is arranged individually by means of support rollers arranged outside the movement path of the tubular goods, the axes of rotation of which extend in the spreading direction of the tubular goods, and which are releasably engaged with the counter-rollers rotatably mounted in the spreading units , We noted in their position that the axes of rotation of the rollers causing the feed also run in the spreading direction, and that at least the feed and support rollers assigned to a guide unit are jointly adjustable in the spreading direction to change the spreading width of the spreader.

Dabei ist es zweckmässig, wenn je eine Vorschub- und eine Abstützrolle auf einer gemeinsamen Drehachse angeordnet sind. Zur einwandfreien Halterung der Spreizeinheiten ist es ausserdem zweckmässig, wenn bezüglich der Warendurchlaufebene gesehen auf der einen Seite jeder Spreizeinheit mindestens zwei Vorschub- und Abstützrollenpaare und auf der anderen Seite mindestens ein Vorschub- und Abstützrollenpaar angeordnet sind, und zwar so, dass kein Kippmoment auf die derart abgestützte Spreizeinheit ausgeübt wird.It is useful if a feed roller and a support roller are arranged on a common axis of rotation. For proper mounting of the spreading units, it is also expedient if at least two pairs of feed and support rollers are arranged on the one side of each spreading unit and at least one pair of feed and support rollers is arranged on the other side, so that there is no tilting moment on the one such supported spreading unit is exercised.

Zur seitlichen Fixierung der Spreizeinheiten ist es vorteilhaft, wenn die Abstützrollen längs ihrem Umfang mit einer formschlüssig mit einer Gegenrolle der abzustützenden Spreizeinheit in Eingriff stehenden Führungsnut versehen sind.For lateral fixing of the spreading units, it is advantageous if the support rollers are provided along their circumference with a guide groove which is positively engaged with a counter roller of the spreading unit to be supported.

Zur Erzielung einer möglichst gleichmässigen Beförderung der Schlauchware über den Breithalter ist es ferner zweckmässig, wenn die einer Spreizeinheit zugeordneten Vorschub- und Abstützrollen mit einem gemeinsamen Antrieb verbunden sind.In order to achieve the most uniform possible conveyance of the tubular goods via the spreader, it is also expedient if the feed and support rollers assigned to a spreading unit are connected to a common drive.

Es ist ausserdem vorteilhaft, wenn die auf den beiden einander abgewandten Seiten einer Spreiz- und Führungseinheit angeordneten Vorschub- und Abstützrollen gegeneinander zu und voneinander weg verstellbar angeordnet sind.It is also advantageous if the feed and support rollers arranged on the two sides of a spreading and guiding unit facing away from one another are arranged such that they can be adjusted relative to and away from one another.

Es ist überdies zweckmässig, wenn zur Stauchung der über den Breithalter beförderten Schlauchware jede der beiden Spreizeinheiten mit mindestens zwei längs der Führungsaussenseiten aufeinanderfolgenden, unterschiedlich schnell angetriebenen, endlos umlaufenden Transportriemen versehen sind.It is also expedient for each of the two spreading units to be provided with at least two continuous, continuously rotating transport belts which are driven at different speeds along the outside of the guide in order to compress the tubular goods conveyed via the spreader.

Es hat sich ferner als vorteilhaft erwiesen, dass die Transportriemen aus gummielastischem Material bestehen und einen kreisförmigen Querschnitt aufweisen.It has also proven to be advantageous that the transport belts consist of rubber-elastic material and have a circular cross section.

Wie aus der Zeichnung ersichtlich, weist die in den Figuren 1 bis 4 dargestellte erste beispielsweise Ausführungsform eines erfindungsgemässen Breithalters zwei im Innern eines zu behandelnden und nur mit seinen Konturen angedeuteten, in flachem Zustand sich befindenden Gestrickschlauches 1 seitlich nebeneinander angeordnete Spreizeinheiten 2 und 3 auf. Die letzteren sind mit je einem längs ihrer Führungsaussenseite verlaufenden endlosen Transportriemen 4 versehen, welche mittels etwa in der Schlauchwaren-Mittelebene sich befindenden, in den beiden Einheiten 2 und 3 angeordneten Umlenkrollen 5, 6 und 7 geführt werden.As can be seen from the drawing, the first exemplary embodiment of a spreader according to the invention shown in FIGS. 1 to 4 has two spreading units 2 and 3 arranged side by side inside a knitted tube 1 to be treated and indicated only with its contours and in a flat state. The latter are each provided with an endless transport belt 4 running along their guide outer side, which are guided by means of deflecting rollers 5, 6 and 7, which are located approximately in the tube center plane and are arranged in the two units 2 and 3.

Die beiden Spreizeinheiten sind gegen die Schlauchauflaufseite zu sich verjüngend ausgebildet, so dass die zugeführte, in ihrer Breite zu dehnende, in flachem Zustand vorliegende Schlauchmaschenware 1 beim Auflaufen auf den Breithalter ganz allmählich in ihrer Breite gedehnt wird.The two spreading units are designed to taper towards the hose run-up side, so that the supplied tubular mesh fabric 1, which is to be stretched in its width and is in a flat state, is very gradually stretched in width when it strikes the spreader.

Zur Halterung der beiden Spreizeinheiten 2 und 3 innerhalb der Schlauchware 1 dienen die von beiden Seiten von aussen über die durchlaufende Schlauchware an diesen angreifenden Vorschubrollen 8,9,10 und 11 sowie die Abstützrollen 12, 13, 14 und 15.To hold the two spreading units 2 and 3 within the tubular goods 1, the feed rollers 8, 9, 10 and 11, which act on the tubular goods from the outside, and the support rollers 12, 13, 14 and 15, serve to hold them from the outside.

Die Vorschubrollen 8 bis 11 stehen in Eingriff mit dem längs der Führungsaussenseite der Spreizeinheit 2 respektive 3 freiliegenden Teil des endlos umlaufenden Transportriemens 4, treiben diesen entsprechend der gewünschten Vorschubgeschwindigkeit der in ihrer Breite zu dehnenden Schlauchware 1 an, und dienen gleichzeitig zur Abstützung der zugeordneten Spreizeinheit 2 respektive 3.The feed rollers 8 to 11 are in engagement with the part of the endlessly circulating transport belt 4, which is exposed along the outside of the guide of the spreading unit 2 or 3, drive it according to the desired feed speed of the tubular goods 1 to be stretched in width, and at the same time serve to support the assigned spreading unit 2 or 3.

Wie insbesondere aus den Figuren 1 und 4 ersichtlich, ist zur Vereinfachung der Konstruktion je eine Vorschub- und eine Abstützrolle zu einem eine einzige Einheit bildenden Rollenpaar, dessen Drehachse 16 senkrecht zur Durchlaufrichtung der zu dehnenden Schlauchware 1 verläuft, zusammengefasst. Die Abstützrollen 12 bis 15 stehen ihrerseits wie insbesondere aus Figur 2 ersichtlich, mit in den zugeordneten Spreizeinheiten 2 respektive 3 drehbar gelagerten Gegenrollen 12, 13, 14 respektive 15 lösbar in Eingriff.As can be seen in particular from FIGS. 1 and 4, one feed roller and one support roller are combined to form a single unit, the axis of rotation 16 of which is perpendicular to the direction of flow of the tubular goods 1 to be stretched, in order to simplify the construction. The support rollers 12 to 15 are in turn releasably engaged, as can be seen in particular from FIG. 2, with counter-rollers 12, 13, 14 and 15 rotatably mounted in the associated spreading units 2 and 3, respectively.

Zur Verstellung der Breite des Breithalters sind die in Figur 1 der rechten Spreizeinheit 2 zugeordneten, zur Abstützung der letzteren dienenden Vorschub- und Abstützrollen 8 bis 15 in einem in Richtung des Pfeiles B quer zur Vorschubrichtung C verstellbaren Schlitten 21 gemeinsam angeordnet.To adjust the width of the spreader, the feed and support rollers 8 to 15 assigned to the right-hand spreading unit 2 in FIG. 1 and serving to support the latter are arranged together in a slide 21 which is adjustable in the direction of arrow B transversely to the feed direction C.

Die Abstützrollen 12 bis 15 sind längs ihrem Umfang mit formschlüssig mit je einer Gegenrolle 17,18,19 bzw. 20 der abzustützenden Spreizeinheit 2 respektive 3 in Eingriff stehenden Führungsnut 22 versehen. Auf diese Weise sichern die in die Führungsnuten 22 der Abstützrollen 12, 13, 14 bzw. 15 eingreifenden und die letzteren abstützenden Gegenrollen 17, 18, 19 bzw. 20, sowie die das Kippmoment aufnehmenden und den Antrieb des Transportriemens 4 sicherstellenden Vorschubrollen 8 bis 11, dass der Spreizteil 2 respektive 3 in seiner innerhalb der durchlaufenden Schlauchware 1 sich befindenden Lage, und zwar parallel und quer zur Bewegungsrichtung der durchlaufenden Schlauchware 1 fixiert ist.The support rollers 12 to 15 are provided along their circumference with a form-fitting, each with a counter roller 17, 18, 19 or 20 of the spreading unit 2 or 3 to be supported, and a guide groove 22 which is in engagement. In this way, the counter rollers 17, 18, 19 and 20, which engage in the guide grooves 22 of the support rollers 12, 13, 14 and 15 and support the latter, as well as the feed rollers 8 to 11 that absorb the tilting moment and ensure the drive of the transport belt 4 that the expansion part 2 or 3 is fixed in its position within the continuous tubular fabric 1, namely parallel and transverse to the direction of movement of the continuous tubular fabric 1.

Zur Erzielung eines gleichmässigen Vorschubes der aufzuweitenden Schlauchware 1 sind alle Vorschub- und Abstützrollen 8 bis 11 bzw. 12 bis 15 mit gleichen Aussendurchmessem versehen und mit einem gemeinsamen Antrieb verbunden.In order to achieve a uniform feed of the tubular goods 1 to be expanded, all feed and support rollers 8 to 11 or 12 to 15 are provided with the same outside diameters and are connected to a common drive.

Um die beiden Spreizeinheiten 2 und 3 aus ihrer durch die Vorschub- und die Abstützrollen 8 bis 11 und 12 bis 15 gebildeten Halterung herausnehmen zu können, sind die auf der einen Seite der Spreizeinheit 2 resp. 3 angeordneten Vorschub-und Abstützrollen 8, 9 bzw. und 12, 13 in einem gemeinsamen Schlitten 23 gelagert, welcher senkrecht zur Schlauchwarenebene verstellbar ist.In order to be able to remove the two spreading units 2 and 3 from their holder formed by the feed and support rollers 8 to 11 and 12 to 15, the two on the one side of the spreading unit. 3 arranged feed and support rollers 8, 9 and and 12, 13 mounted in a common carriage 23 which is adjustable perpendicular to the tubular goods plane.
