Description

Die Erfindung betrifft eine Webmaschine mit einer Antriebseinrichtung und einem über die Webbreite der Webmaschine verlaufenden Querträger, auf dem mindestens eine mit der Antriebseinrichtung verbundene elektrische oder elektronische Schalteinheit angeordnet ist, welche Bedienungselemente insbesondere zum Starten, Anhalten und Steuern der Webmaschine enthält.The invention relates to a weaving machine with a drive device and a cross member running over the weaving width of the weaving machine, on which at least one electrical or electronic switching unit connected to the drive device is arranged, which contains control elements in particular for starting, stopping and controlling the weaving machine.

Ferner betrifft die Erfindung ein Verfahren zum Anbringen einer Schalteinheit der genannten Art an der Webmaschine.The invention further relates to a method for attaching a switching unit of the type mentioned to the weaving machine.

Bei bekannten Webmaschinen der genannten Art sind z.B. drei Schalteinheiten in drei Halterungen untergebracht, von denen jede für sich am Querträger angeschraubt ist. Die bekannten Anordnungen erfordern jeweils einen von der Webmaschine getrennten Zusammenbau der Schalteinheiten, welche dann je für sich am Querträger in der vorgesehenen Betriebsstellung befestigt werden. Der Einbau der bekannten Schalteinheiten erfordert daher einen entsprechenden zusätzlichen Vormontage-und/oder Montageaufwand.In known weaving machines of the type mentioned, e.g. three switching units housed in three brackets, each of which is screwed to the cross member. The known arrangements each require a separate assembly of the switching units from the weaving machine, which are then each attached to the cross member in the intended operating position. The installation of the known switching units therefore requires a corresponding additional pre-assembly and / or assembly effort.

Der Erfindung liegt die Aufgabe zugrunde, eine insbesondere in dieser Hinsicht verbesserte Webmaschine und ein entsprechend vereinfachtes Einbauverfahren zu schaffen, welches eine sichere Positionierung der Schalteinheit und deren Verbindung mit der Antriebseinrichtung in einer gegenüber bisherigen Ausführungen verkürzten Montagezeit gewährleistet.The invention has for its object to provide a weaving machine, particularly improved in this regard, and a correspondingly simplified installation method, which ensures reliable positioning of the switching unit and its connection to the drive device in a shorter assembly time than previous designs.

Diese Aufgabe wird an einer Webmaschine der eingangs genannten Art gemäss der Erfindung dadurch gelöst, dass der Querträger mit mindestens einem schienenartigen Führungsteil für die Schalteinheit versehen ist, und dass die Schalteinheit mindestens eine mit dem Führungsteil verschiebbar zusammenführbare Haltepartie aufweist, und dass dem Führungsteil Mittel zum Feststellen der Schalteinheit zugeordnet sind.This object is achieved on a weaving machine of the type mentioned at the outset according to the invention in that the cross member is provided with at least one rail-like guide part for the switching unit, and in that the switching unit has at least one holding part which can be moved together with the guide part, and in that the guide part has means for Detection of the switching unit are assigned.

Die erfindungsgemässe Anordnung gestattet die Verwendung einbaufertiger, besonders einfach aufgebauter und entsprechend kostengünstiger Schalteinheiten ("prints") mit integrierten Bedienungselementen, wodurch eine bei bisherigen Ausführungen erforderliche Vormontage der Schalteinheiten entfällt. Die Schalteinheiten können vielmehr unmittelbar am Führungsteil angebracht, auf einfache Weise in die vorbestimmte Betriebsstellung verschoben und festgestellt werden. Dies ermöglicht eine erhebliche Kostenund Arbeitsersparnis.The arrangement according to the invention permits the use of ready-to-install, particularly simply constructed and correspondingly inexpensive switching units (“prints”) with integrated operating elements, as a result of which a pre-assembly of the switching units, which was required in previous designs, is eliminated. The switching units can rather be attached directly to the guide part, moved in a simple manner into the predetermined operating position and locked. This enables considerable cost and labor savings.

Das erfindungsgemässe Verfahren zum Anbringen mindestens einer Schalteinheit an der Webmaschine besteht darin, dass die Schalteinheit von einem Ende des Führungsteils her mit diesem zusammengeführt und zumindest über einen Teil seiner Längserstreckung in eine vorbestimmte Betriebsstellung bewegt wird und hierauf in dieser Betriebsstellung festgestellt sowie an ein mit der Antriebseinrichtung verbundenes Steuersystem angeschlossen wird, und dass der Führungsteil an einem Querträger der Webmaschine befestigt wird. Auf diese Weise ist eine rationelle, insbesondere schraubenlose Anbringung der Schalteinheit bzw. mehrerer Schalteinheiten in einer jeweils variablen Betriebsstellung erzielbar.The method according to the invention for attaching at least one switching unit to the weaving machine consists in that the switching unit is brought together with the guide part from one end and is moved at least over part of its longitudinal extent into a predetermined operating position, and is then determined in this operating position and in a position with the Drive device connected control system is connected, and that the guide part is attached to a cross member of the loom. In this way, a rational, in particular screwless attachment of the switching unit or several switching units can be achieved in a variable operating position.

In den Unteransprüchen sind weitere Ausgestaltungen der Erfindung hervorgehoben.Further refinements of the invention are emphasized in the subclaims.

  • Fig. 5 eine Webmaschine entsprechend derjenigen nach Fig. I, in einer abgewandelten Ausführungsform.
Further features result from the following description of exemplary embodiments according to the invention which are shown schematically in the drawing. It shows:
  • FIG. 1 shows a weaving machine equipped according to the invention in a perspective view, seen from the goods side;
  • FIG. 2 shows a detail of the weaving machine according to FIG. I in a partial view in a larger representation;
  • Fig. 3 shows the detail of Figure 2 in a plan view.
  • Fig. 4 is a partial section of the loom along the line IV-IV in Fig. I, and
  • Fig. 5 shows a weaving machine corresponding to that of Fig. I, in a modified embodiment.

Die Webmaschine nach Fig. I enthält ein Maschinengestell mit zwei Seitenwangen I und 2 und zwei diese verbindenden Querträgern 3 und 3a. Zwischen den Seitenwangen I und 2 sind eine Anzahl Webschäfte 4 zur Führung von Kettfäden 30 und zur Bildung eines Webfaches angeordnet. Von einer ausserhalb des Webfaches angeordneten Schussfadenspule 5 wird jeweils ein Schussfaden abgezogen, auf nicht weiter dargestellte Weise, etwa durch Druckluft oder ein Projektil oder durch Greifer in das Webfach eingetragen und in der Spitze des Webfaches an das dort beginnende Gewebe 6 angeschlagen. Das Gewebe 6 wird in bekannter Weise auf einen zwischen den Seitenwangen I, 2 angeordneten Warenbaum 7 aufgewickelt.I contains a machine frame with two side cheeks I and 2 and two cross members 3 and 3a connecting them. A number of heald frames 4 for guiding warp threads 30 and for forming a shed are arranged between the side cheeks I and 2. A weft thread is drawn off from a weft spool 5 arranged outside the shed, in a manner not shown, for example by compressed air or a projectile or by gripper, is inserted into the shed and struck in the tip of the shed on the fabric 6 starting there. The fabric 6 is wound in a known manner onto a fabric tree 7 arranged between the side cheeks 1, 2.

Der Querträger 3 erstreckt sich im wesentlichen oberhalb des Webfaches über die Webbreite der Webmaschine, während der Querträger 3a als sogenannte "Brusttraverse" die warenseitigen Endpartien der Seitenwangen 1 und 2 verbindet. Gemäss Fig. 4 kann der Querträger 3 ein Vierkant-Hohlprofil aufweisen. An der den Webschäften 4 abgewandten Seite des Querträgers 3 ist auf nicht weiter dargestellte Weise, z.B. durch eine Schrauben- oder Klemmverbindung, eine im wesentlichen über die Webbreite sich erstreckende Halteschiene 8 befestigt, die z.B. aus Leichtmetall bestehen kann. Entsprechend der Darstellung nach Fig. 4 sind in der Halteschiene 8 zwei einander gegenüberliegend angeordnete Führungsnuten 9 bzw. 10 ausgebildet, die sich im wesentlichen über die ganze Länge des Querträgers 3 erstrecken. In den Führungsnuten 9 und 10 sind drei über die Längserstreckung des Querträgers 3 verteilte plattenförmige Schalteinheiten II, Ila, Ilb angeordnet, welche durch entsprechende plattenförmige Distanzstücke 12 im Abstand voneinander gehalten werden.The cross member 3 extends essentially above the shed over the weaving width of the weaving machine, while the cross member 3 a, as a so-called “chest cross member”, connects the end portions of the side cheeks 1 and 2 on the goods side. 4, the cross member 3 can have a square hollow profile. On the side of the cross member 3 facing away from the heald frames 4, in a manner not shown further, e.g. fixed by a screw or clamp connection, a substantially across the width of the support rail 8 which e.g. can consist of light metal. 4, two mutually opposite guide grooves 9 and 10 are formed in the holding rail 8, which extend substantially over the entire length of the cross member 3. Arranged in the guide grooves 9 and 10 are three plate-shaped switching units II, Ila, Ilb which are distributed over the longitudinal extent of the cross member 3 and which are kept at a distance from one another by corresponding plate-shaped spacers 12.

Wie insbesondere aus den Fig. 2, 3 und 4 hervorgeht, enthalten die Schalteinheiten II, lla, Ilb je eine Leiterplatte ("print") 13 mit integrierten Schaltverbindungen und Schaltern 14, 15, 16, 17, 18 und 19, die als Knickschalter ausgebildet sein können, welche nicht oder nur um ein sehr geringes Mass über die sie umgebende Einbaufläche der betreffenden Leiterplatte 13 vorstehen. Die Leiterplatten 13 und die Distanzstücke 12 sind je mit zwei an ihren seitlichen Rändern ausgebildeten Haltepartien in den Führungsnuten 9 und 10 parallel zur Längserstreckung des Querträgers 3 verschiebbar geführt. In den für die Betriebsstellungen der Schalteinheiten II, IIa, IIb vorgesehenen Längenabschnitten der Halteschiene 8 sind den Einbaustellungen der Schalter 14 bis 19 entsprechend angeordnete Bedienungsöffnungen 21 ausgebildet, welche die betreffenden Schalter 14 bis 19 zugänglich machen.As can be seen in particular from FIGS. 2, 3 and 4, the switching units II, 11a, 11b each contain a printed circuit board 13 with integrated switching connections and switches 14, 15, 16, 17, 18 and 19, which act as a break switch can be formed, which are not or only to a very small extent over the projecting surrounding installation area of the relevant circuit board 13. The circuit boards 13 and the spacers 12 are each slidably guided parallel to the longitudinal extension of the cross member 3 with two holding parts formed on their lateral edges in the guide grooves 9 and 10. In the longitudinal sections of the holding rail 8 which are provided for the operating positions of the switching units II, IIa, IIb, the installation positions of the switches 14 to 19 are provided with correspondingly arranged operating openings 21 which make the switches 14 to 19 in question accessible.

Bei der dargestellten Ausführung ist im wesentlichen von jedem Abschnitt der Webbreite aus zumindest eine der Schalteinheiten II, IIa, Ilb für die Bedienungsperson leicht erreichbar, um die Webmaschine zu starten oder anzuhalten, so dass die Behebung von Gewebefehlern, insbesondere von Kett- oder Schussfadenbrüchen, entsprechend geringe Stillstandszeiten der Webmaschine erfordert. In jeder der Schalteinheiten II, Ila, Ilb dienen der Schalter 14 zum Starten der Webmaschine, die Schalter 15 und 16 je zum Einschalten eines schrittweisen Rück- bzw. Vorlaufs der Webmaschine, der Schalter 17 zur Synchronisierung der mit dem Webmaschinenantrieb gekoppelten Einrichtungen und der Schalter 18 zum Ausschalten der Webmaschine. Der Schalter 19 kann einen Teil einer "Zweihandverriegelung" bilden, der jeweils zugleich mit dem Schalter 14 bzw. 15 bzw. 16 betätigt werden muss, um eine aus Sicherheitsgründen vorgesehene Verriegelung dieser Schalter 14, 15 und 16 zu lösen. Dadurch wird sichergestellt, dass beim Einschalten der Webmaschine jeweils beide Hände der Bedienungsperson ausserhalb des Bereichs der beweglichen Teile der Webmaschine verbleiben.In the embodiment shown, at least one of the switching units II, IIa, Ilb is essentially within easy reach of each section of the weaving width for the operator to start or stop the weaving machine, so that the removal of fabric defects, in particular warp or weft breaks, correspondingly short downtimes of the weaving machine are required. In each of the switching units II, Ila, Ilb, the switch 14 is used to start the weaving machine, the switches 15 and 16 are used to switch on a stepwise rewinding or advancing of the weaving machine, the switch 17 is used to synchronize the devices coupled to the weaving machine drive, and the switches 18 to switch off the weaving machine. The switch 19 can form part of a "two-hand lock" which must be actuated simultaneously with the switch 14 or 15 or 16 in order to release a locking of these switches 14, 15 and 16 provided for security reasons. This ensures that when the loom is switched on both hands of the operator remain outside the area of the moving parts of the loom.

Die Leiterplatten 13 sind je über einen Verbindungsstecker 22 an ein Flachbandkabel 23 anschliessbar, welches mehrere Steuerleitungen 24 enthält, die mit einer der Antriebseinrichtung 27 der Webmaschine zugeordneten Steuereinrichtung 26 verbunden sind. Ueber die Steuerleitungen 24 ist die Antriebseinrichtung 27 von jeder der Schalteinheiten II, Ila, Ilb aus beeinflussbar. Das Flachbandkabel 23 ist durch einen zwischen dem Querträger 3 und den Leiterplatten 13 sowie den Distanzstücken 12 vorgesehenen Einbauraum 25 geführt und auf nicht weiter dargestellte Weise an die Steuereinrichtung 26 angeschlossen.The circuit boards 13 can each be connected via a connecting plug 22 to a ribbon cable 23 which contains a plurality of control lines 24 which are connected to a control device 26 assigned to the drive device 27 of the weaving machine. Via the control lines 24, the drive device 27 can be influenced from each of the switching units II, Ila, Ilb. The ribbon cable 23 is guided through an installation space 25 provided between the cross member 3 and the printed circuit boards 13 and the spacers 12 and is connected to the control device 26 in a manner not shown.

Die Schalteinheiten II, lla, Ilb sowie die Distanzstücke 12 können jeweils an einem Ende der vom Querträger 3 abgenommenen Halteschiene 8 in die beiden Führungsnuten 9 und 10 eingeführt und in die vorgesehene Betriebsposition verschoben werden, wo sie ohne weitere Befestigungsmittel durch die Distanzstücke 12 festgestellt und auf einfache Weise an die Verbindungsstecker 22 angeschlossen werden können. Hierauf kann die Halteschiene 8 in der dargestellten Betriebsstellung am Querträger 3 befestigt werden. Es ist jedoch auch eine Ausführung möglich, bei der die am Querträger 3 verbleibende Halteschiene 8 mit den Schalteinheiten II, Ila, Ilb bestückt wird.The switching units II, ILA, ILB and the spacers 12 can each be inserted at one end of the holding rail 8 removed from the cross member 3 into the two guide grooves 9 and 10 and shifted into the intended operating position, where they are determined by the spacers 12 and without further fastening means can be easily connected to the connector 22. The holding rail 8 can then be fastened to the cross member 3 in the operating position shown. However, an embodiment is also possible in which the holding rail 8 remaining on the cross member 3 is equipped with the switching units II, Ila, Ilb.

Entsprechend der Darstellung nach Fig. 5 kann eine entsprechende Halteschiene 8 auch an dem als Brusttraverse ausgebildeten Querträger 3a angebracht sein.According to the illustration in FIG. 5, a corresponding holding rail 8 can also be attached to the cross member 3a designed as a crossbeam.

Anstelle der dargestellten einteiligen Halteschiene 8 ist auch eine entsprechende zwei- oder mehrteilige Ausführung möglich. Je nach Webbreite der Webmaschine kann die Halteschiene 8 auch mehr oder weniger als drei Schalteinheiten enthalten, z.B. eine einzige, mittig angeordnete Schalteinheit, welche etwa zwei an den Seitenwangen I und 2 angeordnete Schalteinrichtungen ergänzen kann. Ferner kann anstelle eines Leichtmetallprofils auch etwa ein entsprechendes Kunststoffprofil für die Halteschiene verwendet werden. Es ist auch eine Ausführung möglich, bei der die Führungsbahnen für die Schalteinheiten II, Ila, IIb in den Querträger integriert sind und dieser mit Bedienungsöffnungen 21 für die Schalter 14 bis 19 oder entsprechende Schaltelemente versehen ist. Die Führungsbahnen für die Schalteinheiten können auch an der Aussenseite des Querträgers ausgebildet sein. Zur Führung der Schalteinheiten können ferner anstelle von über die Webbreite verlaufenden Führungsnuten auch entsprechende, quer zur Längserstreckung des Querträgers, z.B. vertikal, verlaufende Führungsbahnen vorgesehen sein, welche jeweils ein Einschieben der Schalteinheiten von oben her in die betreffende Betriebsstellung ermöglichen.Instead of the one-piece holding rail 8 shown, a corresponding two-part or multi-part version is also possible. Depending on the weaving width of the weaving machine, the holding rail 8 can also contain more or less than three switching units, e.g. a single, centrally arranged switching unit, which can complement about two switching devices arranged on the side walls I and 2. Furthermore, instead of a light metal profile, a corresponding plastic profile can also be used for the holding rail. An embodiment is also possible in which the guideways for the switching units II, Ila, IIb are integrated in the crossmember and this is provided with operating openings 21 for the switches 14 to 19 or corresponding switching elements. The guideways for the switching units can also be formed on the outside of the cross member. To guide the switching units, instead of guiding grooves running across the weaving width, it is also possible to use corresponding transverse to the longitudinal extension of the cross member, e.g. vertical, running guideways may be provided, each of which allows the switching units to be inserted from above into the relevant operating position.
