Description

Die Erfindung betrifft eine Anlage zum Herstellen von umreiften Drahtgitterrollen, mit einer Wickelvorrichtung, die einen angetriebenen Wickeldorn zum Aufwickeln des zugeführten Drahtgitters und eine Leiteinrichtung zum Einfädeln des Drahtgitters in den Wickeldorn aufweist, einer Abstreifvorrichtung, mit welcher die gewickelte Drahtgitterrolle relativ zum Wickeldorn in axialer Richtung bewegbar ist, einem Greifermechanismus, der gegen die Mantelfläche der Drahtgitterrolle von oben her und von unten her schwenkbare Greifarme aufweist und mittels einer Transportvorrichtung aus einer ersten Stellung, in welcher er die Drahtgitterrolle im Bereich der Wickelvorrichtung mittels der Greifarme aufnimmt, über eine die Rollenlänge übersteigende Entfernung in Richtung der Wickeldornachse in eine zweite vom Wickeldorn entfernte Stellung bewegbar ist, und einer Umreifungsvorrichtung für die gewickelte Drahtgitterrolle mit einem Umreifungsrahmen für ein Umreifungselement.The invention relates to a system for producing strapped wire mesh rolls, with a winding device which has a driven winding mandrel for winding the supplied wire mesh and a guide device for threading the wire mesh into the winding mandrel, a stripping device with which the wound wire mesh roll relative to the winding mandrel in the axial direction is movable, a gripper mechanism which has gripping arms which can be pivoted from above and from below against the lateral surface of the wire mesh roll and by means of a transport device from a first position in which it picks up the wire mesh roll in the region of the winding device by means of the gripping arms, over a length exceeding the roll length Distance in the direction of the winding mandrel axis in a second position distant from the winding mandrel, and a strapping device for the wound wire mesh roll with a strapping frame for a strapping element.

Eine aus der AT-PS 276.028 bekannte Anlage der einleitend angegebenen Art hat den Nachteil, daß der Greifermechanismus nur passiv mit Hilfe einer Ausstoßplatte von der ersten in die zweite Stellung bewegbar ist, in welcher eine stationäre Umreifungsvorrichtung vorgesehen ist. Eine feinfühlige Arbeitsweise der Umreifungsvorrichtung und eine Anpassung derselben an unterschiedliche Gitterrollendimensionen bzw. Umreifungserfordernisse ist deshalb nicht möglich.A system known from AT-PS 276.028 of the type specified in the introduction has the disadvantage that the gripper mechanism can only be moved passively from the first to the second position with the aid of an ejection plate, in which a stationary strapping device is provided. It is therefore not possible for the strapping device to work sensitively and to adapt it to different mesh roll dimensions or strapping requirements.

Aufgabe der Erfindung ist es, diesen Nachteil zu vermeiden und eine Anlage der einleitend angegebenen Art zu schaffen, mit welcher die Drahtgitterrolle mit Hilfe von Umreifungselementen an beliebigen Stellen der Gitterrollenlänge mit großer Genauigkeit abgebunden werden kann. Die erfindungsgemäße Vorrichtung hat die Merkmale, daß der Greifermechanismus zumindest zwei voneinander unabhängige, mit zugeordneten Halterungen versehene Einheiten von Greifarmen aufweist und mittels eines den Greifermechanismus tragenden, in an sich bekannter Weise auf Schienen verfahrbaren Wagens parallel zur Wickeldornachse gesteuert in frei wählbare Positionen verstellbar ist, und daß der in an sich bekannter Weise senkrecht zur Wickeldornachse verstellbare Umreifungsrahmen ebenfalls auf einem Wagen montiert und mit diesem Wagen parallel zur Wickeldornachse auf Schienen gesteuert in frei wählbare Umreifungspositionen verfahrbar ist, wobei die Greifarme jeder Greifarmeinheit zum Passieren des Umreifungsrahmens von der Drahtgitterrolle gesteuert wegschwenkbar sind.The object of the invention is to avoid this disadvantage and to create a system of the type specified in the introduction with which the wire mesh roll can be tied with great accuracy at any point along the length of the wire mesh roll using strapping elements. The device according to the invention has the features that the gripper mechanism has at least two mutually independent units of gripper arms provided with associated holders and by means of a gripper mechanism load-bearing, in a known manner movable carriage on rails parallel to the mandrel axis is adjustable in freely selectable positions, and that the strapping frame adjustable in a known manner perpendicular to the mandrel axis is also mounted on a trolley and controlled with this carriage parallel to the mandrel axis on rails can be moved into freely selectable strapping positions, the gripping arms of each gripping arm unit being able to be pivoted away from the wire mesh roller in a controlled manner for passing through the strapping frame.

Mit dieser Anlage wird bei im wesentlichen fortlaufender Betriebsweise der Wickelvorrichtung zugleich eine genau gesteuerte Einstellung der Gitterrolle relativ zur Umreifungsvorrichtung erzielt, was einen automatischen Umreifungsvorgang an beliebigen Stellen der Gitterrolle ermöglicht. Dabei werden beim Passieren des Umreifungsrahmens abwechselnd jeweils die Greiferarme einer Einheit weggeschwenkt, während die Greiferarme der verbleibenden Einheiten die Gitterrolle sicher festhalten und damit ein Verwinden, einseitiges Absenken oder ungewolltes Aufrollen der Gitterrolle verhindern.With this system, an essentially controlled setting of the grid roller relative to the strapping device is achieved while the winding device is operating essentially continuously, which enables an automatic strapping process at any point on the grid roller. When passing through the strapping frame, the gripper arms of one unit are alternately pivoted away, while the gripper arms of the remaining units hold the grating roller securely and thus prevent twisting, one-sided lowering or unintentional rolling up of the grating roller.

Bei einer bevorzugten Ausführungsform der Erfindung sind die Halterungen der Greifarmeinheiten durch quer zur Wickeldornachse orientierte, in Richtung dieser Achse relativ zueinander verstellbare Lagerschilde gebildet, die auf dem Wagen des Greifermechanismus montiert sind und an denen oberhalb und unterhalb der Wickeldornachse die Schwenklagerungen für die Greifarme vorgesehen sind. Die Greifarme greifen vorzugsweise mit ihren freien Enden über parallel zur Wickeldornachse verlaufende und vorzugsweise in Richtung parallel zu dieser Achse verstellbare Halteorgane an der Drahtrolle an. Durch diese Ausbildung wird eine sichere und schonende Aufnahme von Drahtgitterrollen unterschiedlicher Durchmesser erreicht.In a preferred embodiment of the invention, the holders of the gripper arm units are formed by bearing plates oriented transversely to the mandrel axis and adjustable relative to one another in the direction of this axis, which are mounted on the carriage of the gripper mechanism and on which the pivot bearings for the gripper arms are provided above and below the mandrel axis . The free ends of the gripping arms preferably engage the wire reel via holding members that run parallel to the winding mandrel axis and are preferably adjustable in the direction parallel to this axis. This design ensures that wire mesh rolls of different diameters are held safely and gently.

Weitere Merkmale der Erfindung werden nachfolgend an einem in der perspektivischen Zeichnung schematisch dargestellten Ausführungsbeispiel näher erläutert.Further features of the invention are explained in more detail below using an exemplary embodiment schematically illustrated in the perspective drawing.

Von einer nicht dargestellten Schweißmaschine zum Herstellen von Drahtgittern oder einem nicht dargestellten Drahtgittervorrat wird eine Gitterbahn G in Richtung des Pfeiles P₁ mit Hilfe von angetriebenen Transport- und Rückhaltewalzen 1, und zwischen einem Paar von Führungswalzen 2 einer nur schematisch dargestellten Wickelvorrichtung 3 zugeführt. Die Wickelvorrichtung 3 weist einen mittels nicht dargestellter Lager- und Antriebseinrichtungen entsprechend dem Doppelpfeil P₂ antreibbaren Wickeldorn 4 sowie ein oberes Leitblech 5 und ein unteres Leitblech 6 auf, die jeweils entsprechend dem Doppelpfeil P₃ aufeinander zu und voneinander weg schwenkbar sind. Zu Beginn des Wickelvorganges werden die Leitbleche 5, 6 gegeneinander geschwenkt und bilden einen Leitdurchgang, über welchen der Anfangsabschnitt der Gitterbahn exakt auf den Wickeldorn 4 geführt wird, wodurch das Einfädeln und Fixieren der Gitterbahn auf dem Wickeldorn 4 erleichtert wird.From a welding machine, not shown, for the production of wire mesh or a wire mesh supply, not shown, a mesh web G is fed in the direction of arrow P 1 with the aid of driven transport and retention rollers 1 and between a pair of guide rollers 2 of a winding device 3, which is only shown schematically. The winding device 3 has a not shown drive and drive devices according to the double arrow P₂ drivable mandrel 4 and an upper guide plate 5 and a lower guide plate 6, which are each pivotable towards and away from each other according to the double arrow P₃. At the beginning of the winding process, the guide plates 5, 6 are pivoted against one another and form a guide passage, via which the initial section of the grid path is guided exactly onto the winding mandrel 4, which facilitates the threading and fixing of the grid path on the winding mandrel 4.

Während des Wickelvorganges wird die Länge der Gitterbahn G mit Hilfe einer den Transport- und Rückhaltewalzen 1 zugeordneten Längenmeßeinrichtung 7 kontinuierlich gemessen. Nach Erreichen der gewünschten Fertigungslänge wird die Gitterbahn mit Hilfe einer der Meßeinrichtung nachgeschalteten Schneideinrichtung 8, die im wesentlichen aus einem mit einem Messer 11 versehenen oberen Scherbalken 9 und einem ebenfalls mit einem Messer versehenen unteren Scherbalken 10 besteht; vom Materialvorrat abgetrennt.During the winding process, the length of the grid web G is continuously measured with the aid of a length measuring device 7 assigned to the transport and retention rollers 1. After the desired production length has been reached, the grid web is cut with the aid of a cutting device 8 connected downstream of the measuring device, which essentially consists of an upper shear bar 9 provided with a knife 11 and a lower shear bar 10 also provided with a knife; separated from the material stock.

Im Schwenkbereich des unteren Leitbleches 6 ist eine Etikettiereinrichtung 12 vorgesehen, die bei vom Drahtgitter weg nach unten geschwenktem unteren Leitblech 6 durch einen Ausschnitt 15 des Leitbleches 6 hindurch um eine Aufhängung 13 aus einer Ausgangsstellung 12' entsprechend dem Doppelpfeil P₄ in eine tangential auf den Wickeldorn 4 weisende Arbeitsstellung 12'' schwenkbar ist, in welcher die Etikettiereinrichtung 12 die Unterseite der Gitterbahn im wesentlichen berührt. Mit der Ettiketiereinrichtung werden kurz vor Vollendung einer Gitterrolle R' Etiketten E, die beispielsweise Produktdaten enthalten, kontinuierlich in die Gitterrolle R' mit eingewickelt. Die Etiketten E werden einem Etikettenvorratsmagazin 14 entnommen und können je nach Bedarf von einem Materialvorrat abgetrennt werden oder auch in Form von Einzelblättern vorliegen. Die Etikettiereinrichtung 12 ist innerhalb des Ausschnittes 15 des unteren Leitbleches 6 entsprechend dem Doppelpfeil P₅ parallel zur Wickeldornachse x-x verstellbar, um die Position der Etikettiereinrichtung 12 an unterschiedliche Breiten der aufzuwickelnden Gitterbahn anpassen sowie die Position des eingewickelten Etikettes E relativ zum Rand der Gitterbahn einstellen zu können.In the swivel range of the lower guide plate 6, a labeling device 12 is provided which, when the lower guide plate 6 is pivoted downward away from the wire mesh, through a cutout 15 of the guide plate 6 around a suspension 13 from an initial position 12 'in accordance with the double arrow P₄ into a tangent to the winding mandrel 4-pointing working position 12 '' is pivotable, in which the labeling device 12 essentially touches the underside of the grid web. With the labeling device, labels E, which contain, for example, product data, are continuously wrapped in the grid roll R '. The labels E are taken from a label supply magazine 14 and can be separated from a material supply as required or can also be in the form of single sheets. The labeling device 12 is adjustable within the cutout 15 of the lower guide plate 6 according to the double arrow P₅ parallel to the mandrel axis xx in order to adapt the position of the labeling device 12 to different widths of the grid web to be wound up and to be able to adjust the position of the wrapped label E relative to the edge of the grid web .

Da die Wickelvorrichtung 3 zum gleichzeitigen Aufwickeln von zwei parallelen Gitterbahnen ausgelegt sein kann oder gegebenenfalls zwei Etiketten pro Gitterrolle gewünscht werden, weist das untere Leitblech 6 einen zweiten Ausschnitt 15' auf, der eine nicht gezeigte zweite Etikettiereinrichtung aufnehmen kann.Since the winding device 3 can be designed for the simultaneous winding of two parallel lattice webs or, if necessary, two labels per lattice roll are desired, the lower guide plate 6 has a second cutout 15 'which can accommodate a second labeling device (not shown).

Ein Transportwagen 16 ist entsprechend dem Doppelpfeil P₆ parallel zur Richtung der Wickeldornachse x-x auf Laufschienen 17 aus einer Übernahmestellung W, in welcher der Wagen die Gitterrolle R' von der Wickelvorrichtung 3 übernimmt, in eine Abbindestellung A verfahrbar. Der Transportwagen 16 trägt mehrere quer zur Wagenlängsrichtung orientierte Lagerschilde 18, an denen je drei, eine Greifarmeinheit bildende Greifarme 19, 20, 21 entsprechend dem Doppelpfeil P₇ um zur Wickeldornachse x-x parallele Achsen schwenkbar gelagert sind. Die Lagerschilde 18 sind relativ zueinander entsprechend dem Doppelpfeil P₈ parallel zur Wickeldornachse x-x verstellbar, um die Relativlage der Greifarme an die Länge der aufzunehmenden Gitterrolle R' anpassen zu können. Kurz vor dem Abtrennen der Gitterbahn vom Materialvorrat werden die Greifarme an die Gitterrolle R' angelegt, wobei die Anpreßkraft so eingestellt wird, daß das abgetrennte Ende der Gitterbahn ohne Beschädigung der Gitterrolle R' aufgewickelt werden kann.A transport carriage 16 can be moved according to the double arrow P₆ parallel to the direction of the mandrel axis x-x on rails 17 from a take-over position W, in which the carriage takes over the grid roller R 'from the winding device 3, into a binding position A. The transport carriage 16 carries a plurality of bearing plates 18 oriented transversely to the longitudinal direction of the carriage, on each of which three gripping arms 19, 20, 21 forming a gripping arm unit are pivotably mounted according to the double arrow P₇ about axes parallel to the mandrel axis x-x. The end shields 18 are adjustable relative to one another in accordance with the double arrow P₈ parallel to the mandrel axis x-x in order to be able to adapt the relative position of the gripping arms to the length of the grid roller R 'to be accommodated. Shortly before separating the grid web from the material supply, the gripping arms are placed on the grid roll R ', the contact pressure being adjusted so that the separated end of the grid web can be wound up without damaging the grid roll R'.

Das an der Gitterrolle R' angreifende freie Ende jedes Greifarmes weist ein rohrförmiges Halteorgan 22 auf, das am freien Ende des Greifarmes parallel zur Wickeldornachse verschiebbar angebracht und in seiner Länge und Ausbildung an die Maschenweite der festzuhaltenden Gitterrolle angepaßt ist. Die drei Arme jeder Greifarmeinheit sind am zugeordneten Lagerschild 18 so montiert, daß die Lagerungen von zwei Armen 20, 21 oberhalb der Wickeldornachse x-x liegen, während die Lagerung eines Armes 19 unterhalb der Wickeldornachse liegt. Die Gitterrolle R' wird von den Greifarmen 19, 20 von unten her abgestützt, wogegen der Greifarm 21 die Gitterrolle R' von oben her niederhält. Die Greifarme 19, 20, 21 einer Greifarmeinheit können einzeln oder gemeinsam mit Hilfe nicht dargestellter Betätigungselemente verschwenkt werden.The free end of each gripper arm that engages the grating roller R ′ has a tubular holding member 22 that is parallel to the winding mandrel axis at the free end of the gripper arm slidably attached and its length and design is adapted to the mesh size of the grid roller to be held. The three arms of each gripper arm unit are mounted on the associated end plate 18 so that the bearings of two arms 20, 21 lie above the mandrel axis xx, while the bearing of an arm 19 is below the mandrel axis. The grating roller R 'is supported by the gripping arms 19, 20 from below, whereas the gripping arm 21 holds down the grating roller R' from above. The gripper arms 19, 20, 21 of a gripper arm unit can be pivoted individually or together with the aid of actuating elements (not shown).

Nach dem vollständigen Aufwickeln einer Gitterrolle R' und dem Anlegen der Greiferarme 19, 20, 21 des Transportwagens 16 wird die Gitterrolle R' vom Transportwagen mitgenommen und zugleich mittels eines entsprechend dem Doppelpfeil P₉ parallel zur Wickeldornachse x-x auf den Laufschienen 17 verstellbaren, eine Durchtrittsöffnung für den Wickeldorn 4 aufweisenden Abstreifwagens 23 vom Wickeldorn 4 abgeschoben. Die Gitterrolle R' wird mittels des Transportwagens 16 aus der Übernahmestellung W in die Abbindestellung A transportiert, die in axialer Richtung so weit außerhalb der Wickelvorrichtung 3 liegt, daß die Gitterrolle R' den Wickeldorn 4 vollständig freigibt. Nach dem Rückstellen des Abstreifwagens 23 in seine Ausgangslage ist die Wickelvorrichtung 3 sofort wieder für das Aufwickeln einer neuen Gitterrolle bereit. Um das Ablösen der Gitterrolle R' vom Wickeldorn 4 zu erleichtern, kann der Wickeldorn 4 entgegen der ursprünglichen Wickelrichtung zurückgedreht werden.After the complete winding of a grid roller R 'and the application of the gripper arms 19, 20, 21 of the transport carriage 16, the grid roller R' is taken along by the transport carriage and at the same time by means of an adjustable opening on the rails 17 by means of a double arrow P₉ parallel to the mandrel axis xx on the running rails 17 the stripping carriage 23 having the mandrel 4 is pushed off the mandrel 4. The grid roller R 'is transported by means of the transport carriage 16 from the take-over position W to the binding position A, which lies in the axial direction so far outside of the winding device 3 that the grid roller R' completely releases the winding mandrel 4. After the stripping carriage 23 has been returned to its initial position, the winding device 3 is immediately ready for winding up a new grid roll. In order to facilitate the detachment of the grid roller R 'from the winding mandrel 4, the winding mandrel 4 can be turned back against the original winding direction.

Zum Abbinden einer in der Abbindestellung A befindlichen Gitterrolle R ist eine Umreifungsvorrichtung 24 vorgesehen. Die Umreifungsvorrichtung 24 weist einen entsprechend dem Doppelpfeil P₁₀ parallel zur Längsachse der abzubindenden Gitterrolle R auf einer Laufbahn 25 verfahrbaren Laufwagen 26 und einen auf dem Laufwagen 26 entsprechend dem Doppelpfeil P₁₁ in Richtung senkrecht zur Gitterrolle R verstellbaren Ständer 27 auf. Vom Ständer 27 kragt ein Umreifungsrahmen 28 aus, der die abzubindende Gitterrolle R umschließt und ein, im Umreifungsrahmen 28 liegendes Umreifungsband B in Form einer Schlinge B' um die Gitterrolle R herum legt. Das Umreifungsband B kann im Rahmen der Erfindung unterschiedliche Formen haben und aus den verschiedensten Materialien, wie z.B. Kunststoff- oder Metallbändern, bestehen. Im Umreifungsrahmen 28 sind nicht dargestellte Elemente für die Umreifung, wie ein Vorratsmagazin für das Umreifungsband, ein Verschlußaggregat sowie eine Schneideinrichtung für das Umreifungsband untergebracht.A strapping device 24 is provided for tying a grid roller R in the tying position A. The strapping device 24 has a corresponding to the double arrow P₁₀ parallel to the longitudinal axis of the lattice roller R to be tied on a track 25 movable carriage 26 and a on the carriage 26 according to the double arrow P₁₁ in the direction perpendicular to the lattice roller R adjustable stand 27. From stand 27 protrudes a strapping frame 28, which surrounds the lattice roll R to be tied and places a strapping band B lying in the strapping frame 28 in the form of a loop B 'around the lattice roll R. The strapping B can have different shapes within the scope of the invention and can consist of a wide variety of materials, such as plastic or metal straps. In the strapping frame 28, not shown elements for strapping, such as a storage magazine for the strapping, a sealing unit and a cutting device for the strapping are accommodated.

Zum Abbindevorgang wird die Umreifungsvorrichtung 24 entsprechend dem Doppelpfeil P₁₀ parallel zur Längsachse der abzubindenden Gitterrolle R an eine Stelle gebracht, an der das Umreifungsband B um die Gitterrolle R gelegt werden soll. Anschließend wird der Ständer 27 entsprechend dem Doppelpfeil P₁₁ so weit gegen die Gitterrolle R verschoben, daß die ständerseitige Innenseite des Umreifungsrahmens 28 genau an der Gitterrolle R anliegt. Die Schlinge B' des Umreifungsbandes wird zugezogen, an der Verschlußstelle verschlossen und das Umreifungsband anschließend vom Materialvorrat abgetrennt. Anschließend fährt der Ständer 27 entsprechend dem Doppelpfeil P₁₁ in seine Ausgangslage zurück.For the setting process, the strapping device 24 is brought according to the double arrow P₁ Gitter parallel to the longitudinal axis of the lattice roll R to be tied to a point at which the strapping B is to be placed around the lattice roll R. Then the stand 27 is moved so far against the grid roller R according to the double arrow P₁₁ that the stand-side inside of the strapping frame 28 is exactly against the grid roller R. The loop B 'of the strapping is pulled shut, closed at the point of closure and the strapping is then separated from the material supply. Then the stand 27 moves back to its starting position according to the double arrow P₁₁.

Um die Gitterrolle R an einer weiteren Stelle ihrer Länge mit einem Umreifungsband B zu versehen, wird die Umreifungsvorrichtung 24 mit Hilfe des Laufwagens 26 entsprechend dem Doppelpfeil P₁₀ entlang des feststehenden Transportwagens 16 und damit entlang der Gitterrolle R verstellt und an einer neuen Stelle positioniert. Im Rahmen der Erfindung ist es auch möglich, die Umreifungsvorrichtung 24 ortsfest anzuordnen und den Transportwagen 16 mit der abzubindenden Gitterrolle R entsprechend dem Doppelpfeil P₆ so weit zu verschieben, daß das Umreifungsband B' im Umreifungsrahmen 28 mit der zu umreifenden neuen Stelle auf der Gitterrolle R fluchtet.In order to provide the lattice roll R at a further point in its length with a strapping B, the strapping device 24 is adjusted with the help of the carriage 26 according to the double arrow P₁₀ along the fixed transport carriage 16 and thus along the lattice roll R and positioned at a new location. In the context of the invention, it is also possible to arrange the strapping device 24 in a stationary manner and to move the trolley 16 with the lattice roller R to be tied according to the double arrow P₆ so far that the strapping band B 'in the strapping frame 28 with the new location to be strapped on the lattice roller R. flees.

Da Greifarme der einzelnen Greifarmeinheiten die Relativbewegungen zwischen Umreifungsvorrichtung 24 und Transportwagen 16 behindern würden, werden zur Vermeidung einer Kollision jeweils die Greifarme einer Einheit kurzzeitig so weit von der Drahtgitterrolle weggeschwenkt, wie dies beispielsweise für den oberen Greifarm bei 21' dargestellt ist, daß die Greifarme den Umreifungsrahmen 28 ungehindert passieren können. Nachdem die Kollisionsgefahr zwischen dem Umreifungsrahmen 28 und den entsprechenden Greifarmen einer Einheit gebannt ist, schließen die Greifarme sofort wieder um die Gitterrolle R. Da die übrigen geschlossenen Greifarme während der Öffnungs- und Schließbewegung einer Greifarmeinheit befähigt sein müssen, die Gitterrolle R weiterhin sicher in ihrer Lage festzuhalten, wird die Anzahl der je eine Greifarmeinheit tragenden Lagerschilde 18 und außerdem die Länge der rohrförmigen Halteorgane 22 an die Länge der abzubindenden Gitterrolle R angepaßt, wobei aber mindestens zwei Lagerschilde 18 für den Transportwagen 16 erforderlich sind.Since gripper arms of the individual gripper arm units, the relative movements between strapping device 24 and Transport car 16 would hinder, each to avoid a collision, the gripper arms of a unit are briefly pivoted as far away from the wire mesh roll, as is shown for example for the upper gripper arm at 21 ', that the gripper arms can pass the strapping frame 28 unhindered. After the risk of collision between the strapping frame 28 and the corresponding gripping arms of a unit is eliminated, the gripping arms immediately close around the grating roller R. Since the remaining closed gripping arms must be capable of opening and closing movement of a gripping arm unit, the grating roller R continues to be secure in its To hold the position, the number of end shields 18 each carrying a gripper arm unit and also the length of the tubular holding members 22 are adapted to the length of the grid roller R to be set, but at least two end shields 18 are required for the transport carriage 16.

Nach Beendigung des Umreifungsvorganges wird die Umreifungsvorrichtung 24 in ihre Ausgangslage zurückgestellt bzw. der Transportwagen 16 so weit verschoben, daß die fertig umreifte Gitterrolle R nach Öffnung aller Greifarme über ein geneigtes, zweckmäßig kippbares Abrollblech 29 in Richtung des Pfeiles P₁₂ abrollen kann. Um den Abrollvorgang zu ermöglichen, sind die Lagerschilde 18 quer zur Wickeldornachse x-x im wesentlichen bogenförmig ausgebildet und bilden mit entsprechenden Abschrägungen 18' eine Abrollbahn für die Gitterrolle R.After completion of the strapping process, the strapping device 24 is returned to its initial position or the trolley 16 is shifted so far that the fully strapped grid roller R can roll over an inclined, appropriately tiltable rolling plate 29 in the direction of the arrow P 12 after opening all the gripping arms. In order to enable the unrolling process, the end shields 18 are essentially arch-shaped transversely to the mandrel axis x-x and, with corresponding bevels 18 ', form a unrolling path for the grid roller R.

Die zur Durchführung der Bewegungen der einzelnen Vorrichtungen und Elemente der erfindungsgemäßen Anlage notwendigen Betätigungs- und Steuereinrichtungen sind in der Zeichnung der Übersicht halber weggelassen. Insbesondere ist eine zentrale Steuereinrichtung für den gesamten Arbeitszyklus vorgesehen.The actuation and control devices required to carry out the movements of the individual devices and elements of the system according to the invention are omitted in the drawing for the sake of clarity. In particular, a central control device is provided for the entire working cycle.

Die Oberflächenbeschaffenheit aller mit der aufzuwickelnden Gitterbahn G sowie mit der abzubindenden Gitterrolle R in Berührung kommenden Vorrichtungen (1, 2, 4, 5, 6, 7, 18', 22, 29) ist an die Oberflächenbeschaffenheit der Drahtgitter derart angepaßt, daß eine Beschädigung der Drahtgitteroberfläche vermieden wird. Beispielsweise werden zum Aufwickeln und Abbinden von kunststoffbeschichteten Drahtgittern die Vorrichtungen vorzugsweise mit gummierten Oberflächen versehen.The surface quality of all devices (1, 2, 4, 5, 6, 7, 18 ', 22, 29) that come into contact with the grid web G to be wound up and with the grid roller R to be tied is adapted to the surface quality of the wire grid such that a Damage to the wire mesh surface is avoided. For example, the devices are preferably provided with rubberized surfaces for winding and setting plastic-coated wire grids.

Es versteht sich, daß die erläuterte Anlage verschiedentlich abgewandelt werden kann. So können beispielsweise anstelle der rohrförmigen Halteorgane schalenförmige Halteorgane vorgesehen werden, die es gegebenenfalls ermöglichen, mit nur zwei Greifarmen pro Greifarmeinheit auszukommen. Je nach der Größe der aufzunehmenden Drahtgitterrolle und der Ausbildung der Halteorgane können auch nur zwei Greifarmeinheiten auf dem Transportwagen vorgesehen werden.It is understood that the system described can be modified in various ways. For example, instead of the tubular holding members, cup-shaped holding members can be provided, which may make it possible to make do with only two gripping arms per gripping arm unit. Depending on the size of the wire mesh roll to be accommodated and the design of the holding members, only two gripper arm units can also be provided on the trolley.
