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 gehaltenen, verstellbaren Breithalter für in flachem Zustand vorliegende Schlauchware, mit mindestens zwei im Inneren der letzteren seitlich nebeneinander anzuordnenden Spreiz- und Führungseinheiten, welche mit mindestens je einem über einen Teil ihres Umfanges längs der Führungsaussenseite der zugeordneten Führungseinheit verlaufenden endlosen Transportriemen versehen sind, welche mit auf der Aussenseite der durchzulaufenden Schlauchware sich befindenden Vorschubrollen lösbar in Eingriff stehen.The invention relates to an externally held, adjustable spreader for tubular goods present in a flat state, with at least two spreading and guiding units to be arranged laterally next to one another inside the latter, each with at least one endless over a part of its circumference running along the outside of the guiding unit of the associated guiding unit Transport belts are provided, which are releasably engaged with feed rollers located on the outside of the tubular goods to be passed through.

Aus der DE-PS 29 39 085 sowie den US-PSen 25 53 074 und 34 79 706 sind im Innern einer Schlauchware anzuordnende Breithalter in Form eines flachen, durch Teleskoprohre weitenverstellbaren Rahmens bekannt, bei denen die Teleskoprohre an ihren äusseren Enden über Kopfteile mit dem Rahmen verbunden sind.From DE-PS 29 39 085 and US Pat. Nos. 25 53 074 and 34 79 706 are to be arranged in the interior of a tubular fabric spreader in the form of a flat, by telescopic tubes width-adjustable frame known in which the telescopic tubes at their outer ends with the headboards Frames are connected.

Diese bereits bekannten Breithalter weisen jedoch alle den gravierenden Nachteil auf, dass sie nur innerhalb relativ enger Grenzen über die Teleskoprohre in ihrer Breite verstellbar sind. Ein Verstellen des Breithalters bei durchlaufender Schlauchware, zum Beispiel bei aneinandergehängter Schlauchware unterschiedlicher Breite, ist nicht möglich. Aendert 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. 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 Schlauchware von aussen her möglich ist.However, these already known spreader bars all have the serious disadvantage that their width can only be adjusted via the telescopic tubes within relatively narrow limits. It is not possible to adjust the spreader when the tubular goods are running through, for example when the tubular goods are of different widths. If the width of the continuous tubular goods changes, then their feed must be interrupted, the goods of different widths 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. The object of the present invention is to provide a B broad holder which does not have the aforementioned disadvantages of the previously known spreaders, 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 in place.

Diese Aufgabe wird bei einem Breithalter der eingangs genannten Art erfindungsgemäss dadurch gelöst, dass jede der Führungseinheiten mittels von aussen angreifender Abstützrollen, deren Drehachsen senkrecht zur Durchlaufrichtung der Schlauchware verlaufen, und die mit in-den Führungseinheiten drehbar gelagerten Gegenrollen lösbar in Eingriff stehen, in ihrer Lage gehalten wird, 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 the case of a spreader of the type mentioned at the outset in that each of the guide units by means of support rollers acting externally, the axes of rotation of which run perpendicular to the direction of travel of the tubular goods, and which are releasably engaged in their counter-rollers rotatably mounted in the guide units Position is held, and that at least the feed and support rollers assigned to a guide unit for changing the spreading width of the spreader are arranged together adjustable in the spreading direction.

Dabei ist es zweckmässig, wenn je eine Vorschub- und eine Abstützrolle auf einer gemeinsamen Drehachse angeordnet sind. Zur einwandfreien Halterung der Spreiz- und Führungseinheiten ist es ausserdem zweckmässig, wenn bezüglich der Warendurchlaufebene gesehen auf der einen Seite jeder Spreiz- und Führungseinheit 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 Spreiz-und Führungseinheit 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 and guide units, it is also expedient if at least two pairs of feed and support rollers are arranged on the one side of each spreading and guide unit, and at least one pair of feed and support rollers is arranged on the other side, as seen in relation to the goods throughput level that no tilting moment is exerted on the spreading and guiding unit supported in this way.

Zur seitlichen Fixierung der Spreiz- und Führungseinheiten ist es vorteilhaft, wenn die Abstützrollen längs ihrem Umfang mit einer parallel zu ihrer Drehachse formschlüssig mit einer Gegenrolle der abzustützenden Spreiz- und Führungseinheit in Eingriff stehenden Führungsnut versehen sind.For lateral fixing of the spreading and guiding units, it is advantageous if the support rollers are provided along their circumference with a guide groove which is in positive engagement with a counter roller of the spreading and guiding unit to be supported, parallel to its axis of rotation.

Zur Erzielung einer möglichst gleichmässigen Beförderung der Schlauchware über den Breithalter ist es ferner zweckmässig, wenn die einer Spreiz- und Führungseinheit 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 an expansion and guide 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 Spreiz-und Führungseinheiten mit mindestens zwei längs der Führungsaussenseiten aufeinanderfolgenden, unterschiedlich schnell angetriebenen, endlos umlaufenden Transportriemen versehen sind.It is also expedient if, in order to compress the tubular goods conveyed via the spreader, each of the two spreading and guiding units is provided with at least two endless belts which are driven in succession at different speeds along the outside of the guideway.

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 Spreiz- und Führungseinheiten 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 and guiding units 2 and 2 arranged laterally next to one another inside a knitted tube 1 to be treated and indicated only with its contours and in a flat state 3 on. The latter are each provided with an endless transport belt 4 which runs along their guide outer side and which are guided by means of deflection rollers 5, 6 and 7, which are located approximately in the middle plane of the tubular goods and are arranged in the two units 2 and 3.

Die beiden Spreiz- und Führungseinheiten 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 allmä'hlich in ihrer Breite gedehnt wird.The two spreading and guiding 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 gradually expanded in width when it strikes the spreader.

Zur Halterung der beiden Spreiz- und Führungseinheiten 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 and guide units 2 and 3 within the tubular fabric 1, the feed rollers 8, 9, 10 and 11, which act on the tubular material from the outside and the supporting rollers 12, 13, 14 and 15, serve from the outside.

Die Vorschubrollen 8 bis 11 stehen in Eingriff mit dem längs der Führungsaussenseite der Spreiz- und Führungseinheit 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 Spreiz- und Führungseinheit 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 and expansion unit 2 and 3, respectively, drive it according to the desired feed speed of the tubular material 1 to be stretched in width, and at the same time serve as support the assigned spreading and guiding unit 2 and 3 respectively

Wie insbesondere aus den Figuren 1 und 4 ersichtlich, ist zur Vereinfachung der Konstruktion je eine Vorschub- und eine Abstutzrolle 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 Spreiz- und Führungseinheiten 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, to simplify the construction, one feed roller and one support roller are each to form a pair of rollers forming a single unit; the axis of rotation 16 of which extends perpendicular to the direction of flow of the tubular goods 1 to be stretched. The support rollers 12 to 15 are in turn releasably engaged, as can be seen in particular in FIG. 2, with counter-rollers 12, 13, 14 and 15 rotatably mounted in the associated spreading and guide units 2 and 3, respectively.

Zur Verstellung der Breite des Breithalters sind die in Figur 1 der rechten Spreiz- und Führungseinheit 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 and guide 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 je einer parallel zu ihrer Drehachse 16 formschlüssig mit je einer Gegenrolle 17,18,19 bzw. 20 der abzustützenden Spreiz-und Führungseinheit 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 Spreiz- und Führungsteil 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, each with a form-fitting parallel to their axis of rotation 16, each with a counter roller 17, 18, 19 or 20 of the expanding and guiding unit 2 or 3 to be supported. 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 spreading and guiding part 2 and 3, respectively, is fixed in its position within the continuous tubular fabric 1, 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 Aussendurchmessern 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 and 12 to 15 are provided with the same outside diameters and connected to a common drive.

Um die beiden Spreiz- und Führungseinheiten 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 Spreiz- und Führungseinheit 2 resp. 3 angeordneten Vorschub- und Abstützrollen 8,9 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 and guide units 2 and 3 from their holder formed by the feed and support rollers 8 to 11 and 12 to 15, the one on the side of the spreading and guide unit 2 and. 3 arranged feed and support rollers 8, 9 and 12, 13 are mounted in a common carriage 23, which is adjustable perpendicular to the tubular goods plane.

In Figur 5 ist ein Schnitt ähnlich Fig.2 durch eine zweite beispielsweise Ausführungsform eines erfindungsgemässen Breithalters dargestellt, wobei hier im Gegensatz zum vorangehend beschriebenen ersten Ausführungsbeispiel nur drei Vorschub- und Abstützrollenpaare 8,9,10 resp. 12,13,14 vorgesehen sind, die über eine gemeinsame Antriebskette 24 angetrieben werden. Teile, welche zu Teilen des vorangehend beschriebenen ersten Ausführungsbeispieles analog sind, sind mit den gleichen Ueberweisungszeichen versehen, so .dass sich eine nochmalige Beschreibung dieser Teile erübrigt.FIG. 5 shows a section similar to FIG. 2 through a second exemplary embodiment of a spreader according to the invention, whereby in contrast to the previously described first exemplary embodiment, only three pairs of feed and support rollers 8, 9, 10, respectively. 12, 13, 14 are provided which are driven by a common drive chain 24. Parts that are part of the previous described first embodiment are analog, are provided with the same reference symbols, so that a repeated description of these parts is unnecessary.
