Description

Die Erfindung betrifft einen Kettbaum-Hubwagen zum Wechseln des Kettbaumes in Webmaschinen, wobei der Kettbaum mittels Steckachsen in der Webmaschine aufgenommen ist und der Hubwagen einen schwenkbar gelagerten Tragholm aufweist, in dessen freien und offenen Enden an die Kettbaumlänge anpaßbare Schiebeholme eingesetzt sind und wobei jeder Schiebeholm einen Rohrgreifer aufweisenden Tragarm besitzt.The invention relates to a warp beam pallet truck for changing the warp beam in weaving machines, the warp beam being received in the weaving machine by means of thru axles and the pallet truck having a pivotally mounted supporting beam, in the free and open ends of which sliding beams which can be adjusted to the length of the warp beam are inserted, and each sliding beam has a support arm having a pipe gripper.

Bekannt sind Kettbaum-Hubwagen mit hydraulisch bewegbaren Tragholmen und mit in dem Tragholm axial verschiebbar aufgenommenen Tragarmen, die mit einem Rohrgreifer zur Aufnahme des Kettbaumrohres ausgerüstet sind.
Diese Tragarme verfügen über eine Höhenfeineinstellung um ein einwandfreies Entnehmen und Einlegen der Steckachsen beim Kettbaumwechsel zu gewährleisten. Das heißt, insbesondere vor Einlegen der Steckachse müssen die Tragarme des Hubwagens mit dem Kettbaumrohr sowohl in der Höhe, als auch in der Tiefe exakt auf das Lager der Steckachsen in der Webmaschine ausgerichtet sein. Die Lagerbohrung für die Steckachse und die Steckachsenaufnahme im Kettbaumrohr müssen fluchtend gegenüberliegen, um die Steckachsen in die Aufnahme des Kettbaumrohres einschieben zu können.
Aufgrund des erheblichen Gewichtes des den vollen Kettbaum tragenden Hubwagens ist ein feinfühliges Verschieben und Ausrichten des Hubwagens von Hand nur schwer möglich und daher äußerst zeitaufwendig.
Nach dem Einsetzen des Kettbaumes in die Webmaschine muß dieser des weiteren noch seitlich zur Webmaschine ausgerichtet werden, um einen parallelen und rechtwinkligen Fadenverlauf vom Kettbaum zu den Webschäften zu gewährleisten. Auch dieses Ausrichten ist zeitaufwendig und beeinträchtigt die Produktivität der Webmaschine.
Beim Entnehmen des leeren Kettbaumes aus der Webmaschine müssen die Tragarme des Hubwagens ebenfalls exakt in der Höhe und Tiefe auf das Kettbaumrohr ausgerichtet sein. Erfolgt ein derartiges Ausrichten nur ungenau, ist ein Herausziehen der Steckachsen in Folge der zwischen der Steckachse und ihren Aufnahmen bestehenden Haftreibung nicht möglich.
Bei einer Steckachsenverbindung zwischen Kettbaum und Webmaschine sind deshalb nur äußerst geringe Maßabweichungen bei der Positionierung des Hubwagens gegenüber dar Webmaschine zulässig.Kettbaum pallet trucks with hydraulically movable support bars and with support arms axially displaceably received in the support bar are known, which are equipped with a pipe gripper for receiving the warp beam pipe.
These support arms have fine height adjustment to ensure that the thru axles can be removed and inserted correctly when changing the warp beam. That means, in particular before inserting the thru axle, the support arms of the lifting truck with the warp beam tube must be precisely aligned with the bearing of the thru axles in the weaving machine, both in height and in depth. The bearing bore for the quick-release axle and the quick-release axle holder in the warp beam tube must lie opposite one another in order to be able to insert the quick-release axles into the receptacle of the warp beam tube.
Due to the considerable weight of the pallet truck carrying the full warp beam, it is difficult to move and align the pallet truck by hand with great difficulty and is therefore extremely time-consuming.
After the warp beam has been inserted into the weaving machine, it must also be aligned laterally to the weaving machine in order to have a parallel and right-angled thread course from the warp beam to ensure the heald frames. This alignment is also time-consuming and affects the productivity of the weaving machine.
When the empty warp beam is removed from the weaving machine, the lifting arms of the lifting truck must also be precisely aligned in height and depth with the warp beam tube. If such alignment is only inaccurate, it is not possible to pull out the thru axles as a result of the static friction existing between the thru axle and its receptacles.
With a thru-axle connection between the warp beam and the weaving machine, therefore, only extremely small dimensional deviations are permissible when positioning the lifting truck compared to the weaving machine.

Aufgabe der Erfindung ist es daher, einen Kettbaum-Hubwagen der vorgenannten Art derart in Verbindung mit einer Webmaschine weiter zu entwickeln, daß ein dreidimensionales Positionieren des Kettbaum-Hubwagens an der Webmaschine ermöglicht wird, ohne daß zum Zwecke des Herstellens und Lösens der Steckachsenverbindung zwischen Kettbaum und Webmaschine ein manuelles Nachjustieren an der Kettbaumaufnahme notwendig wird.The object of the invention is therefore to develop a Kettbaum pallet truck of the aforementioned type in connection with a weaving machine in such a way that three-dimensional positioning of the Kettbaum pallet truck on the weaving machine is made possible without the purpose of producing and releasing the thru-axle connection between the warp beam and loom a manual readjustment on the warp beam holder is necessary.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß an den Schiebeholmen, parallel zu den mit dem Rohrgreifer ausgerüsteten Tragarmen ein den Fahrweg des Hubwagens in die Webmaschine begrenzender Tiefenanschlag vorgesehen ist und mit dem Tiefenanschlag korrespondierende Mittel zur Nivellierung des Rohrgreifers an das Kettbaumrohr in Verbindung stehen und daß der Hubwagen und die Webmaschine auf wenigstens einer Seite ihrer sich diametral gegenüberliegenden Arbeitseinheiten Vorkehrungen zur Seitenfixierung des Hubwagens in der Webmaschine aufweisen.
In weiterer Ausgestaltung der Erfindung korrespondieren jeder Tiefenanschlag und die die Tragarme nivellierenden Mittel mit dem jeweiligen die Steckachse aufnehmenden Steckachsenlager der Webmaschine.
Als Tiefenanschlag fungiert ein fest mit dem Schiebeholm verbundener Träger, der mit seinem freien Ende mittig an das Gehäuse des Steckachsenlagers der Webmaschine zur Anlage kommt. Zweckmäßigerweise ist das freie Ende des Trägers mit einem höhenverstellbaren Anschlagelement ausgerüstet, dessen an das Lagergehäuse zur Anlage kommende Fläche leicht ballig ausgebildet ist.
Um zu sichern, daß der Kettbaum so von den Tragarmen des Hubwagens aufgenommen ist, daß ein ungehindertes Verbinden von Kettbaum und Webmaschine mittels der Steckachsen gewährleistet wird, sind erfindungsgemäß nivellierende Mittel vorgesehen, die mögliche Niveauunterschiede zwischen der Steckachsenaufnahme des Kettbaumrohres und dem Steckachsenlager der Webmaschine vollständig ausgleichen. Die nivellierenden Mittel bestehen dabei aus einem vorzugsweise am Tiefenanschlag angeordneten, um eine Achse drehbar gelagerten Schwenkhebel, dessen freier Arm, der das Steckachsenlager der Webmaschine übergreift, eine die Nivellierung bestimmende Rolle aufnimmt.
Ferner ist der Schwenkhebel mit einer sich vorzugsweise am Tiefenanschlag abstützenden Betätigungseinrichtung verbunden, die beispielsweise eine hydraulisch betriebene Kolben-Zylindereinheit, ein Linearmotor oder eine z.B. von Hand betätigbare Gewindespindel sein kann.
Um die Nivellierung vollziehen zu können ist ferner vorgesehen, daß die Schiebeholme zusammen mit den Tragholmen um wenigstens einen den Betrag des Niveauunterschiedes, der im Millimeterbereich liegen kann, äquivalenten Drehwinkelbetrag drehbeweglich sind.
Dazu ist der Tragholm schwenkbar in einer Hubwagen-Traverse aufgenommen.
Des weiteren wird die Nivellierrolle des Schwenkhebels, in Fahrrichtung des Hubwagens auf die Webmaschine gesehen, vorzugsweise hinter der geometrischen Längsachse des Gehäuses der Steckachsenlager auf dem Lagergehäuse zur Anlage gebracht. Schließlich sind an der Webmaschine Vorkehrungen zur seitlichen Positionierung des Hubwagens in der Webmaschine getroffen, die aus einem vorzugsweise im Bereich des Lagergehäuses der Steckachsen fest angeordneten Fixierelement bestehen, das mit den seitenfixierenden Vorkehrungen an den Hubwagen die Führung des Hubwagens unmittelbar vor dem Erreichen seiner Betriebsstellung in der Webmaschine gewährleistet. Diese seitenfixierenden Vorkehrungen bestehen dabei aus wenigstens zwei im Bereich des Tiefenanschlags achsparallel angeordneten Fixierrollen.According to the invention the object is achieved in that a depth stop limiting the travel of the lifting truck into the weaving machine is provided on the sliding spars, parallel to the supporting arms equipped with the pipe gripper, and corresponding means for leveling the pipe gripper to the warp beam tube are connected to the depth stop and that the pallet truck and the weaving machine have arrangements on at least one side of their diametrically opposed working units for lateral fixation of the pallet truck in the weaving machine.
In a further embodiment of the invention, each depth stop and the means leveling the support arms correspond to the respective thru-axle bearing of the weaving machine that receives the thru-axle.
A support, which is firmly connected to the sliding beam, acts as the depth stop and comes with its free end to the center of the housing of the thru-axle bearing of the weaving machine. The free end of the carrier is expediently equipped with a height-adjustable stop element, the surface of which comes into contact with the bearing housing is slightly spherical.
In order to ensure that the warp beam is received by the support arms of the lifting truck in such a way that an unimpeded connection of the warp beam and the weaving machine is ensured by means of the thru axles, leveling means according to the invention are provided which completely compensate for the possible level differences between the thru-axle receptacle of the warp beam tube and the thru-axle bearing of the weaving machine compensate. The leveling means consist of a pivot lever, preferably arranged on the depth stop and rotatably mounted about an axis, the free arm of which, which engages over the thru-axle bearing of the weaving machine, holds a role determining the leveling.
Furthermore, the swivel lever is connected to an actuating device, which is preferably supported on the depth stop, which can be, for example, a hydraulically operated piston-cylinder unit, a linear motor or a threaded spindle that can be actuated by hand, for example.
In order to be able to carry out the leveling, it is further provided that the sliding bars, together with the carrying bars, can be rotated by at least an amount of rotation angle equivalent to the amount of the level difference, which can be in the millimeter range.
For this purpose, the support bar is pivotally mounted in a pallet truck crossbar.
Furthermore, the leveling roller of the swivel lever, viewed in the direction of travel of the lifting truck on the weaving machine, is preferably brought to bear on the bearing housing behind the geometric longitudinal axis of the housing of the thru-axle bearings. Finally, there are precautions on the side of the weaving machine Positioning of the lifting truck in the weaving machine, which consist of a fixing element which is preferably arranged fixedly in the region of the bearing housing of the thru axles and which ensures the guidance of the lifting truck with the side-fixing arrangements on the lifting truck immediately before it reaches its operating position in the weaving machine. These side-fixing arrangements consist of at least two fixing rollers arranged axially parallel in the area of the depth stop.

Der Vorteil des erfindungsgemäßen Kettbaum-Hubwagens besteht darin, daß das bisher notwendige und manuelle Ausrichten des dem Kettbaum aus der Webmaschine heraushebenden und in die Maschine einsetzenden Kettbaum-Hubwagens vollständig entfällt. Damit werden im Gegensatz zu den bekannten Vorgehensweisen zur Herstellung der Steckachsenverbindung zwischen Kettbaum und Webmaschine die Steckachsen und Achsenaufnahmen schonender behandelt und damit die Lebensdauer von Steckachse und vorallem der Lager erheblich verlängert. Mit der erfindungsgemäßen Lösung wird ferner entscheidend auf die Reduzierung der für einen Kettbaumwechsel bisher veranschlagten Zeit Einfluß genommen und die Produktivität der Webmaschine erhöht.The advantage of the warp beam pallet truck according to the invention is that the previously necessary and manual alignment of the warp beam pallet truck lifting the warp beam out of the weaving machine and inserting it into the machine is completely eliminated. In contrast to the known procedures for establishing the thru-axle connection between the warp beam and the weaving machine, the thru-axles and axle receptacles are treated more gently and the life of the thru-axle and, in particular, the bearings is considerably extended. The solution according to the invention also has a decisive influence on reducing the time previously estimated for a warp beam change and increases the productivity of the weaving machine.

Gemäß Fig. 1 ist die Webmaschine 3 nur schematisch dargestellt. Die Webmaschine 3 verfügt über ein linkes Steckachsenlager bzw. Lagergehäuse 5 und ein rechtes Steckachsenlager 5', in denen die entsprechenden Steckachsen 4,4' axial verschiebbar aufgenommen sind.
Der in der Webmaschine 3 aufgenommene Kettbaum 2, bestehend aus den auf einem Kettbaumrohr in gegenseitigem Abstand angeordneten Kettbaumscheiben, wird an seinen Rohrenden, die ein Kupplungselement für die Steckachsen aufweisen, von der jeweiligen Steckachse 4,4' aufgenommen.
Der ebenfalls schematisch dargestellte Kettbaum-Hubwagen 1 besteht für Kettbäume, die über Steckachsen mit der Webmaschine gekuppelt sind, gemäß der Erfindung im wesentlichen aus einer Traverse 22, die in ihren Traversenarmen einen drehbeweglich gelagerten Tragholm 6 aufnimmt. An beiden Seiten des Tragholmes 6, der als rohrförmiger Körper ausgebildet ist, sind Schiebeholme 7,7' vorgesehen, die axial im Tragholm 6 verschiebbar gelagert und durch entsprechende Arretiermittel 6a,6b mit dem Tragholm lösbar verbunden sind.
An den freien Enden der Schiebeholme 7,7' ist fest mit diesen ein als Träger ausgebildeter Tiefenanschlag 9,9' verbunden, der, wie in Fig. 2 zu erkennen ist, mit dem Lagergehäuse 5,5' zur Anlage kommt. Ferner nimmt jeder Schiebeholm 7,7' einen axial auf dem Schiebeholm verstellbaren Tragarm 9,9' auf, der an seinem freien Ende als Rohrgreifer 8,8' ausgebildet ist. Aufgrund der axialen Verschiebbarkeit der Tragarme 9,9' sind diese an die jeweilige Breite der Kettbaumaufnahmen anpaßbar.1, the loom 3 is only shown schematically. The weaving machine 3 has a left thru-axle bearing or bearing housing 5 and a right thru-axle bearing 5 ', in which the corresponding thru axles 4, 4' are axially displaceably received.
The warp beam 2 accommodated in the weaving machine 3, consisting of the warp beam disks arranged on a warp beam tube at a spacing from one another, is received at its tube ends, which have a coupling element for the thru axles, by the respective thru axis 4, 4 '.
The warp beam lifting carriage 1, also shown schematically, for warp beams which are coupled to the weaving machine via thru axles, according to the invention essentially consists of a crossmember 22, which receives a rotatably mounted support beam 6 in its crossmember arms. On both sides of the support beam 6, which is designed as a tubular body, sliding beams 7, 7 'are provided, which are axially displaceably mounted in the support beam 6 and are detachably connected to the support beam by corresponding locking means 6a, 6b.
At the free ends of the sliding beams 7, 7 ', a depth stop 9, 9' designed as a carrier is firmly connected to them, which, as can be seen in FIG. 2, comes into contact with the bearing housing 5, 5 '. Furthermore, each sliding spar 7, 7 'receives a support arm 9, 9' which is axially adjustable on the sliding spar and which is designed at its free end as a tubular gripper 8, 8 '. Due to the axial displaceability of the support arms 9, 9 ', these can be adapted to the respective width of the warp beam receptacles.

Fig. 1 zeigt ferner ein an der Webmaschine 3 angeordnetes Fixierelement 25, mit einer keilförmig ausgebildeten Nase und parallel verlaufende Zentrierflächen, an die im Bereich des Tiefenanschlages 10 des Hubwagens 1 achsparallel angeordnete Zentrier- oder Fixierrollen 31 auflaufen.
In Fig. 2 bis 4 sind die den Tragarmen 9,9' nivellierenden Mittel dargestellt. Die den Tragarm 9,9' in der Höhe nivellierenden Mittel 15,15' bestehen dabei aus einer am Tiefenanschlag drehbeweglich befestigten Kolben-Zylindereinheit 21,21', deren Kolbenstange 20,20' mit einem ebenfalls am Tiefenanschlag 9,9' drehbeweglich angeordneten Schwenkhebel 18,18' verbunden ist. Die Schwenkhebel 18,18' sind dabei so ausgebildet, daß sie bei am Lagergehäuse 5,5' anliegendem Tiefenanschlag 10,10' das Lagergehäuse 5,5' derart übergreifen, daß die am freien Ende des Schwenkhebels 18,18' angeordnete Nivellierrolle 19,19' außermittig und zwar hinter der Längsachse 24 des Lagergehäuses 5,5' auf dem Lagergehäuse zur Anlage kommt. Diese außermittige Anlage hat den Vorteil, daß die auf das Lagergehäuse 5,5' von der Kolben-Zylindereinheit 21,21' erzeugte und über die Nivellierrolle 19,19' auf das Lagergehäuse ausgeübte Kraft dafür sorgt, daß der Kettbaum-Hubwagen 1 und damit der Tiefenanschlag 10,10' während des Nivelliervorganges in der Anschlagposition an der Webmaschine verbleibt. Das heißt, es wird eine Kraft wirksam, die den Tiefenanschlag 10,10' an das Lagergehäuse 5,5' heranzieht.Fig. 1 also shows a arranged on the loom 3 Fixing element 25, with a wedge-shaped nose and parallel centering surfaces, against which centering or fixing rollers 31 arranged axially parallel run in the area of the depth stop 10 of the lifting truck 1.
2 to 4, the means leveling the support arms 9, 9 'are shown. The means 15, 15 ', which level the support arm 9.9' in height, consist of a piston-cylinder unit 21, 21 'which is rotatably attached to the depth stop and whose piston rod 20, 20' has a swivel lever which is also rotatably arranged on the depth stop 9.9 ' 18, 18 'is connected. The pivot levers 18, 18 'are designed such that when the depth stop 10, 10' is in contact with the bearing housing 5.5 ', they overlap the bearing housing 5.5' in such a way that the leveling roller 19, which is arranged at the free end of the pivot lever 18, 18 ', 19 'off-center, namely behind the longitudinal axis 24 of the bearing housing 5.5' on the bearing housing. This eccentric system has the advantage that the force generated on the bearing housing 5.5 'by the piston-cylinder unit 21.21' and exerted on the bearing housing via the leveling roller 19.19 'ensures that the Kettbaum pallet truck 1 and thus the depth stop 10, 10 'remains in the stop position on the weaving machine during the leveling process. This means that a force acts which pulls the depth stop 10, 10 'against the bearing housing 5.5'.

Aus Fig. 3 ist zu erkennen, daß der Rohrgreifer 8,8' das Kettbaumrohr 11,11' in den Bereich der Steckachsenverbindung gehoben hat und dabei zwischen dem Achsenkreuz 26 von Steckachsenlager und Achsenkreuz 27 von Kettbaumrohr ein Differenzmaß "h" besteht, das durchaus auch den Betrag Null haben kann, also der Rohrgreifer 8,8' vor der notwendigen Nivellierung der Tragarme 9,9' das Kettbaumrohr in die für die Steckachsenverbindung exakte Position angehoben hat. Dies ist jedoch ein Ausnahmefall. Das Differenzmaß "h" wird durch die nivellierenden Mittel 15,15' beseitigt. Dadurch ist ein einwandfreies Einschieben und Herausnehmen der Steckachse 4,4' gewährleistet.From Fig. 3 it can be seen that the pipe gripper 8,8 'has the Kettbaumrohr 11,11' in the region of the thru-axle connection and there is a difference dimension "h" between the axis cross 26 of the thru-axle bearing and the axis cross 27 of Kettbaumrohr can also have the amount zero, that is, the pipe gripper 8,8 'has raised the warp beam pipe into the exact position for the thru-axle connection before the necessary leveling of the support arms 9,9'. However, this is an exception. The difference measure "h" is determined by the leveling means 15, 15 ' eliminated. This ensures that the stub axle 4, 4 'is inserted and removed correctly.

In Fig. 4 ist am freien Ende des Tiefenanschlages 10,10' ein verstellbares Anschlagelement 28 gezeigt, welches zentrisch in die mit einem Blech 29 verschlossene Stirnseite des Tiefenanschlages 10,10' eingeschraubt und über Kontermutter 32 gesichert ist. Die an das Lagergehäuse 5,5' zur Anlage kommende Fläche 30 des Anschlagelementes 28 ist vorzugsweise ballig gestaltet, um eine Punktanlage zu erreichen und um sich eventuell aus der Nivellierung des Tragarmes 9,9' ergebende vertikale Verschiebungen zwischen Tragarm 9,9' und Gehäuselager 5,5' reibungsarm zu vollziehen.
Über ein nicht dargestelltes Einstellelement ist ferner die Nivellierrolle 19,19' am Schwenkhebel 18,18' in ihrer Höhe, entsprechend Pfeilrichtung 33 einstellbar.In FIG. 4, an adjustable stop element 28 is shown at the free end of the depth stop 10, 10 ', which is screwed centrally into the end face of the depth stop 10, 10', which is closed with a metal sheet 29, and secured by means of a lock nut 32. The surface 30 of the stop element 28 which comes into contact with the bearing housing 5.5 'is preferably spherical in order to achieve a point contact and in order to result in vertical displacements between the support arm 9.9' and the housing bearing which may result from the leveling of the support arm 9.9 ' 5.5 'to be carried out with little friction.
The leveling roller 19, 19 'on the pivot lever 18, 18' can also be adjusted in height in accordance with the direction of the arrow 33 via an adjusting element (not shown).

Die Funktion des Kettbaum-Hubwagens 1 ist nun wie folgt:
Der Kettbaum-Hubwagen 1 fährt mit dem vollen Kettbaum 2 in Einfahrrichtung 23 bis zu der durch die Tiefenanschläge 10,10' vorgegebenen Position parallel in die Webmaschine 3. Vor Erreichen der vorgegebenen Position wird die Seitenfixierung 14 des Hubwagens 1 in der Webmaschine 3 wirksam, indem die keilförmig ausgebildete Nase des Fixierelementes, das an der Webmaschine angeordnet ist, zwischen die Fixierrollen 31 gelangt. Der motorbetriebene Kettbaum-Hubwagen 1 fährt mit seinen Tiefenanschlägen 10,10' bis an die Lagergehäuse 5,5' der Webmaschine 3. Nachdem die vorgegebene Position, die z.B. optisch oder akustisch signalisiert werden kann, erreicht ist, wird durch hydraulische Beaufschlagung des Arbeitszylinders der Kolben-Zylindereinheit 21,21' die Nivellierrolle 19,19' des Schwenkhebels 18,18' auf die Lagergehäuse 5,5' zur Anlage gebracht. Dabei ist der Kettbaum 2 in der Position gehalten, daß Steckachsenlager 5,5' und Steckachsenaufnahme in dem Kettbaumrohr nahezu fluchtend gegenüberliegen. Die Tragarme werden nun zusammen mit dem Kettbaum mittels der nivellierenden Mittel auf die notwendige Position angehoben. Die Steckachsenlager 5,5' und die Steckachsenaufnahmen in den Kettbaumrohr 11,11' stimmen jetzt fluchtend überein.
Die Steckachsen 4,4' können nun ohne Mühe den Kettbaum 2 in der Webmaschine 3 aufnehmen. Nachfolgend werden die nivellierenden Mittel 15 geöffnet, damit die Tragarme 9,9' des Hubwagens 1 abgesenkt werden können. Der Kettbaum-Hubwagen wird danach parallel zur Webmaschine aus selbiger unter Entkupplung der Seitenfixierung herausgefahren und für einen nächsten Kettbaumwechsel vorbereitet.The function of the Kettbaum pallet truck 1 is now as follows:
The warp beam lifting carriage 1 moves with the full warp beam 2 in the direction of entry 23 up to the position predetermined by the depth stops 10, 10 ′ in parallel into the weaving machine 3. Before the predetermined position is reached, the side fixation 14 of the lifting carriage 1 in the weaving machine 3 becomes effective. in that the wedge-shaped nose of the fixing element, which is arranged on the weaving machine, passes between the fixing rollers 31. The motor-operated Kettbaum pallet truck 1 travels with its depth stops 10, 10 'to the bearing housing 5.5' of the weaving machine 3. After the predetermined position, which can be signaled optically or acoustically, for example, is reached by hydraulic action on the working cylinder Piston-cylinder unit 21,21 'brought the leveling roller 19,19' of the pivot lever 18,18 'onto the bearing housing 5.5'. The warp beam 2 is held in the position that thru axle bearing 5.5 'and thru axle receptacle in the warp beam tube almost face to face. The support arms are now raised to the required position together with the warp beam using the leveling means. The thru-axle bearings 5.5 'and the thru-axle receptacles in the warp beam tube 11.11' are now in alignment.
The thru axles 4, 4 'can now easily accommodate the warp beam 2 in the weaving machine 3. The leveling means 15 are subsequently opened so that the support arms 9, 9 ′ of the lifting truck 1 can be lowered. The warp beam pallet truck is then moved out of it parallel to the weaving machine by uncoupling the side fixation and prepared for a next warp beam change.
