Description

Die Erfindung betrifft eine Anlage zum automatischen Zuführen von vollen Kannen zu und zum Abführen leerer Kannen von Spinnstellen einer Spinnmaschine gemäss Oberbegriff des Anspruches 1, sowie ein Verfahren zum Betrieb der Anlage.The invention relates to a system for automatically feeding full cans to and for removing empty cans from spinning positions of a spinning machine according to the preamble of claim 1, and a method for operating the system.

In Spinnereien werden häufig mehrere grosse Spinnmaschinen parallel zueinander angeordnet, wobei die einzelnen Spinnmaschinen an zwei Seiten eine Vielzahl von Spinnstellen, beispielsweise 20 bis 200 aufweisen, die das zu verspinnende Faserband aus Kannen erhalten, die auf dem Boden stehend unter den Spinnstellen angeordnet sind. In der Regel sind pro Spinnstelle zwei Kannen vorgesehen, wobei aus einer Kanne das zu verspinnende Band entnommen wird und die andere Kanne entweder als Reserve voll ist oder bereits leer ist. In der Regel wird das Band aus der vorderen, in der ersten Reihe stehenden Kanne entnommen. Sobald diese leer ist, wird sie durch die in der zweiten Reihe stehende volle Kanne ersetzt. Das Zubringen, Auswechseln und Überwachen der Kannen an den Spinnstellen ist relativ zeitraubend und umständlich.In spinning mills, several large spinning machines are often arranged parallel to one another, the individual spinning machines having a large number of spinning positions on two sides, for example 20 to 200, which receive the sliver to be spun from cans which are arranged on the floor under the spinning positions. As a rule, two cans are provided for each spinning station, the sliver to be spun being taken from one can and the other can either being full as a reserve or already empty. As a rule, the tape is removed from the front can, which is in the first row. As soon as it is empty, it is replaced by the full jug in the second row. The feeding, changing and monitoring of the cans at the spinning positions is relatively time-consuming and cumbersome.

Aus der DE-OS 2646313 ist nun eine Anlage der eingangs genannten Art bekannt, mit der ein automatisches Kannenwechsein an derSpinnstelle einer Spinnmaschine möglich ist. Die zur Verwendung gelangende Förderanlage ist eine Hängebahn, deren Schienen an der Spinnmaschine angeordnet sind. Der Förderwagen enthält zwei Ausleger, wobei ein Ausleger zur Aufnahme einer leeren Kanne an der Spinnstelle und zum Abführen und ein Ausleger zum Zuführen und Abgeben einer vollen Kanne an der Spinnstelle dient. Um die an einer Spinnstelle hintereinander stehenden Kannen manipulieren zu können sind 3 oder 4 Kannen benachbarter Spinnstellen auf einem Drehtisch angeordnet, der von Einrichtungen des Förderwagens betätigbar ist. Diese Anlage besitzt den Nachteil, dass alle Spinnstellen mit derart komplizierten Drehtischen ausgerüstet sein müssen, wodurch die Anlage teuer und schwerfällig ist. Insbesondere ist der nachträgliche Einbau einer solchen Förderanlage an bestehende Spinnmaschinen vielfach nicht möglich und in jedem Falle kompliziert und teuer.From DE-OS 2646313 a system of the type mentioned is now known, with which an automatic can change is possible at the spinning position of a spinning machine. The conveyor system used is a monorail, the rails of which are arranged on the spinning machine. The trolley contains two booms, one boom for receiving an empty can at the spinning station and for removal and one boom for feeding and dispensing a full can at the spinning station. In order to be able to manipulate the cans standing one behind the other at a spinning station, 3 or 4 cans of adjacent spinning stations are arranged on a rotary table which can be actuated by devices of the trolley. This system has the disadvantage that all spinning positions must be equipped with such complicated turntables, which makes the system expensive and cumbersome. In particular, the subsequent installation of such a conveyor system on existing spinning machines is often not possible and is complicated and expensive in any case.

Aufgabe der Erfindung ist es, eine Anlage der eingangs genannten Art zu schaffen, die besonders einfach ist und möglichst wenig Eingriffe in die Spinnmaschine erfordert, sodass sie auch nachträglich an bestehende Spinnmaschinen anbaubar ist.The object of the invention is to provide a system of the type mentioned which is particularly simple and requires as little intervention in the spinning machine as possible, so that it can also be retrofitted to existing spinning machines.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruches 1 gelöst. Durch den zusätzlichen dritten Ausleger zum zeitlich begrenzten Erfassen einer an der Spinnstelle im Einsatz befindlichen Kanne lassen sich die Kannen an den Spinnstellen manipulieren, ohne dass komplizierte Drehtische erfordenich sind. Dadurch istdieanlage äusserst einfach und erfordert praktisch keine Eingriffe in bestehende Spinnmaschinen, sodass ein nachträglicher Einbau auch an bereits bestehende Spinnmaschinen möglich ist.The object is achieved by the characterizing features of claim 1. Thanks to the additional third bracket for the temporary detection of a can in use at the spinning station, the cans can be manipulated at the spinning stations without the need for complicated rotary tables. This makes the system extremely simple and requires practically no intervention in existing spinning machines, so that retrofitting is also possible on existing spinning machines.

Die Anlage kann auf verschiedene Arten betrieben werden. Besonders vorteilhaft ist ein Betrieb nach Anspruch 10.The system can be operated in different ways. Operation according to claim 10 is particularly advantageous.

Vorteilhafte Ausgestaltungen der Anlage sind in den Ansprüchen 2 bis 9 beschrieben.Advantageous embodiments of the system are described in claims 2 to 9.

Für die Aufnahme der Kannen an den Auslegern der Förderwagen ergeben sich verschiedene Ausgestaltungsmöglichkeiten. So wäre es beispielsweise möglich, die Kannen mittels Greifer zu erfassen, die eine Kanne umgreifen. Da jedoch die einzelnen Kannen an den Spinnstellen sehr dicht aneinander stehen, ist eine Ausgestaltung nach Anspruch 2 vorteilhafter, die praktisch keinen seitlichen Raum an den Kannen beansprucht. Gemäss Anspruch 3 kann zur Aufnahme der Kanne an der Tragsäule ein unterer Stützansatz vorhanden sein. Dabei ist eine Weiterbildung nach Anspruch 4 von Vorteil, um die Kanne an dem Stützansatz zu halten. Dieser Halt der Kanne kann noch durch eine Weiterbildung des Niederhaltes nach Anspruch 5 verbessert werden.There are various design options for mounting the cans on the outriggers of the trolleys. For example, it would be possible to grasp the cans by means of grippers that grip around a can. However, since the individual cans are very close to one another at the spinning positions, an embodiment according to claim 2 is more advantageous which practically does not take up any lateral space on the cans. According to claim 3, a lower support shoulder can be provided for receiving the jug on the support column. A further development according to claim 4 is advantageous in order to hold the jug on the support attachment. This hold of the jug can be improved by developing the hold-down device according to claim 5.

Besonders vorteilhaft ist eine Ausgestaltu ng des Halters nach Anspruch 6, da dann eine Kanne am oberen Rand erfasst und angehoben werden kann. Es können dann untere Stützansätze entfallen, wodurch die Zugänglichkeit des Auslegers und das Ergreifen einer Kanne verbessert wird. Bei einer Ausgestaltung des Halters nach Anspruch 7 ergibt sich eine besonders flache Bauart, da die horizontal legbage Klemmbacke die Zugänglichkeit des Halters nicht beeinträchtigt, sodass dieser beim Einfahren über die Kanne nur wenig über die Höhe der Kanne angehoben werden muss.A configuration of the holder according to claim 6 is particularly advantageous since a jug can then be grasped and raised at the upper edge. Lower support lugs can then be omitted, which improves the accessibility of the boom and the grip of a jug. In a configuration of the holder according to claim 7, there is a particularly flat design, since the horizontally legbage jaw does not impair the accessibility of the holder, so that it only has to be raised slightly above the height of the can when it is moved in via the can.

Besonders vorteilhaft ist eine Ausgestaltung nach Anspruch 8, wodurch der Ausleger feststellen kann, welchen Füllstand eine aufgenommene Kanne aufweist.An embodiment according to claim 8 is particularly advantageous, as a result of which the boom can determine which fill level a picked up can has.

Automatische Förderanlagen sind hinlänglich bekannt. Dabei kann die Förderanlage als Hängebahn oder als schienengebundene Flurförderanlage ausgebildet sein. Besonders vorteilhaft ist jedoch eine Ausbildung nach Anspruch 9, da hier die geringsten baulichen Eingriffe in bestehende Räume und Anlagen erforderlich sind. Der Förderwagen kann längs einer am Boden angeordneten Leitspur, beispielsweise in Form eines Leitkabels oder einer am Boden angeordneten Leitspur, die beispielsweise aus einem Metallstreifen oder einem optisch wirksamen Streifen bestehen kann, geführt werden.Automatic conveyor systems are well known. The conveyor system can be designed as a monorail or as a rail-bound floor conveyor system. However, a design according to claim 9 is particularly advantageous since the least structural intervention in existing rooms and systems is required here. The trolley can be guided along a guide track arranged on the floor, for example in the form of a guide cable or a guide track arranged on the floor, which can consist, for example, of a metal strip or an optically effective strip.

Die Figur 1 zeigt den Grundriss bzw. das Schema einer Anlage mit mehreren Spinnmaschinen 21, 22, 23, die parellel zueinander und mit Abstand voneinander angeordnet sind. Jede Spinnmaschine weist auf jeder Seite eine Anzahl Spinnstellen 41, bis 4n auf. An jeder Spinnstelle sind zwei Kannen 6 hintereinander angeordnet, sodass an jeder Seite der Maschine zwei Reihen, d.h. eine vordere Reihe 10 und eine hintere Reihe 12 solcher Kannen vorhanden ist. Die Kannen stehen auf dem Boden 14 unterhalb der Spinnstelle, wobei die Kannen 6 der hinteren Reihe 12 teilweise unterhalb des Maschinengestells 16 stehen. Wie insbesondere aus den Figuren 2 bis 4 hervorgeht, wird aus einer Kanne 6 ein Band 18 aus Fasern abgezogen und der Spinnstelle 4 zugeführt.Figure 1 shows the floor plan or the scheme of a system with several spinning machines 2 1 , 2 2 , 2 3 , which are arranged parallel to each other and spaced apart. Each spinning machine has a number of spinning positions 4 1 to 4 n on each side. At each spinning station two cans 6 are arranged one behind the other, so that there are two rows on each side of the machine, ie a front row 10 and a rear row 12 of such cans. The cans stand on the floor 14 below the spinning station, the cans 6 of the rear row 12 partially standing below the machine frame 16. As can be seen in particular from FIGS. 2 to 4, a band 18 of fibers is drawn off from a can 6 and fed to the spinning station 4.

Eine Flurförderanlage 20 mit selbsttätig fahrbaren Flurförderwagen 22 verbindet eine Versorgungsstation 24 und eine Kannenabgabestation 26 mit den Spinnstellen 4 der Spinnmaschinen 2, bis 23. Jeder Flurförderwagen enthält eine erste Steuervorrichtung 28 für den automatischen Fahrbetrieb und eine zweite Steuervorrichtung 30 mit einem Steuerprogramm zum automatischen Aufnehmen und Abgeben von Kannen. Die Flurförderwagen 22 fahren längs einer Leitspur 32. An Verzweigungsstellen 34, bis 346 sind Kodmarkierungen 36, bis 366 neben der Leitspur 32 angeordnet, auf die die erste Steuervorrichtung 28 anspricht und entsprechend einem eingegebenen Zielcode selbsttätig das Ziel d.h. die Spinnstelle anfährt. In den Streckenabschnitten 38, bis 386 längs der Spinnmaschinen 2, bis 23 sind die einzelnen Spinnstellen durch Markierungen 40, bis 40n am Boden gekennzeichnet. Durch einfaches Abzählen der Markierungen findet der Flurförderwagen 22 die einprogrammierte Spinnstelle 4. An jeder Spinnstelle ist ein Befehlsgeber 42, bis 42n angeordnet, der zum Abrufen des Flurförderwagens dient und über eine Leitungs- oder Funkverbindung 44 mit der Versorgungsstation 24 in Verbindung steht, um dort einen Flurförderwagen abzurufen. Die Anlage ist so ausgestaltet, dass ein Flurförderwagen stets in Vorwärtsfahrt und ohne zu wenden jede Seite einer Spinnmaschine 2, bis 23 erreichen kann. Flurförderanlagen mit selbsttätig fahrbaren Flurförderwagen, die für eine Anlage der vorliegenden Art geeignet sind, sind mehrfach bekannt, so beispielsweise aus den US-PSen 2996137, 3147817, 3482644, insbesondere 3 628 624, 3 948 342, 4 015 680 usw.An industrial conveyor system 20 with an automatically movable industrial truck 22 connects a supply station 24 and a can dispensing station 26 to the spinning stations 4 of the spinning machines 2 to 2 3 . Each industrial truck contains a first control device 28 for automatic driving and a second control device 30 with a control program for automatically picking up and dispensing cans. The industrial trucks 22 travel along a guide track 32. At branching points 34, to 34 6 , code markings 36, to 36 6 are arranged next to the guide track 32, to which the first control device 28 responds and automatically approaches the target, ie the spinning station, in accordance with an entered target code. In the sections 38, to 38 6 along the spinning machines 2, to 2 3 , the individual spinning positions are identified by markings 40, to 40 n on the floor. By simply counting the markings, the industrial truck 22 finds the programmed spinning station 4. A command transmitter 42, to 42 n is arranged at each spinning station, which is used to call up the industrial truck and is connected to the supply station 24 via a line or radio connection 44 to retrieve an industrial truck there. The system is designed in such a way that an industrial truck can always reach each side of a spinning machine 2 to 2 3 without moving and without turning. Industrial conveyors with automatically movable industrial trucks that are suitable for a system of the present type are known several times, for example from US Pat. Nos. 2996137, 3147817, 3482644, in particular 3,628,624, 3,948,342, 4,015,680 etc.

Jeder Flurförderwagen 22 weist einen ersten Ausleger 46 zur Aufnahme einer vollen Kanne V an der Versorgungsstation 24 auf und zur Abgabe an eine Spinnstelle. Ein zweiter Ausleger 48 dient zum Aufnehmen einer leeren Kanne L an einer Spinnstelle. Ein dritter Ausleger 50 dient zum zeitlich begrenzten Erfassen einer an einer Spinnstelle im Einsatz befindlichen Kanne E, um diese zurückzunehmen und gegebenenfalls aus einer Reihe 10 in die andere Reihe 12 zu versetzen. Wie insbesondere aus den Figuren 2 bis 4 hervorgeht, weist jeder Ausleger eine Tragsäule 52 auf, die sich am unteren Ende über schwenkbare Rollen 54 am Boden 14 abstützt. Die Tragsäule 52 ist mittels ausfahrbarer Schubstangen 56, 58 mit dem Fahrgestell 60 des Flurförderwagens 22 verbunden. Die Schubstangen werden im vorliegenden Beispiel aus einem teleskopierbaren Kolben/Zylinder-Aggregat 62 gebildet, welches vorzugsweise hydraulisch betätigt wird. An der Tragsäule 52 sind in der unteren Hälfte seitliche Stützarme 64 angeordnet, die am Umfang einer Kanne angreifen. Weiter ist die Tragsäule 52 mit einem Halter 66 ausgestattet, um eine Kanne am Ausleger zu halten. In einem ersten Ausführungsbeispiel gemäss Figur 2 weist die Tragsäule 52 am unteren Ende einen Stützansatz 68 zum Absetzen einer Kanne auf. Der Halter 66 ist als Niederhalter ausgebildet, der in vertikaler Richtung bewegbar ist und die Kanne vorzugsweise übergreift. Nahe der Tragsäule 52 besitzt der Niederhalter 66 einen in die Kanne eingreifenden Halteansatz 70, um die Kanne an der Tragsäule 52 zu halten.Each industrial truck 22 has a first boom 46 for receiving a full can V at the supply station 24 and for delivery to a spinning station. A second boom 48 is used to hold an empty can L at a spinning station. A third boom 50 is used for the time-limited detection of a can E in use at a spinning station, in order to take it back and, if necessary, to move it from one row 10 to the other row 12. As can be seen in particular from FIGS. 2 to 4, each boom has a support column 52 which is supported at the lower end by pivotable rollers 54 on the floor 14. The support column 52 is connected to the chassis 60 of the industrial truck 22 by means of extendable push rods 56, 58. In the present example, the push rods are formed from a telescopic piston / cylinder unit 62, which is preferably actuated hydraulically. On the support column 52, lateral support arms 64 are arranged in the lower half, which engage on the circumference of a can. The support column 52 is also equipped with a holder 66 in order to hold a jug on the boom. In a first exemplary embodiment according to FIG. 2, the support column 52 has a support attachment 68 at the lower end for setting down a can. The holder 66 is designed as a hold-down device which can be moved in the vertical direction and preferably overlaps the jug. In the vicinity of the support column 52, the hold-down device 66 has a holding projection 70 which engages in the can in order to hold the can on the support column 52.

Bei der Ausführungsvariante gemäss Figur 3 besitzt die Tragsäule 52 keinen unteren Stützansatz und der Halter 72 ist als vertikal bewegbarer Galgen ausgebildet. Der Halter weist einen horizontalen, den Rand der Kanne übergreifenden Arm 74 auf, an dem nach unten vorstehende Klemmbakken 76, 78 angeordnet sind. Diese können über nicht näher dargestellte Mittel geöffnet und geschlossen werden. Zum Ansetzten des Auslegers sind die Klemmbacken 76, 78 geöffnet und der Arm 74 vertikal so weit ausgefahren, dass die Klemmbacken 76, 78 den Rand der Kanne überfahren können. Dann wird der Halter 72 abgesenkt, bis die Klemmbacken 76, 78 den oberen Rand einer Kanne übergreifen. Die nicht näher dargestellten Mittel dienen dann zum Festspannen der Klemmbacken 76, 78, wodurch die Kanne sicher am Ausleger gehalten ist. Durch erneutes Ausfahren des Halters 72 in vertikaler Richtung kann die Kanne angehoben werden, sodass sie zum Verfahren die notwendige Bodenfreiheit aufweist, wie dies in Figur 3 dargestellt ist. Die festgeklemmten Klemmbacken 76, 78 reichen aus, um die Kanne zu halten, sodass auf einen unteren Stützansatz 68 verzichtet werden kann. Seitliche Stützarme 64 gewährleisten den ausreichenden seitlichen Halt.In the embodiment variant according to FIG. 3, the support column 52 has no lower support shoulder and the holder 72 is designed as a vertically movable gallows. The holder has a horizontal arm 74 which overlaps the edge of the can and on which downwardly projecting clamping jaws 76, 78 are arranged. These can be opened and closed by means not shown. To attach the boom, the clamping jaws 76, 78 are open and the arm 74 is extended vertically so far that the clamping jaws 76, 78 can drive over the edge of the can. Then the holder 72 is lowered until the jaws 76, 78 overlap the upper edge of a jug. The means, not shown, are then used to clamp the jaws 76, 78, whereby the jug is securely held on the boom. By retracting the holder 72 in the vertical direction, the can can be raised so that it has the necessary ground clearance for moving, as shown in FIG. 3. The clamped jaws 76, 78 are sufficient to hold the jug, so that a lower support shoulder 68 can be dispensed with. Lateral support arms 64 ensure sufficient lateral support.

Figur 4 zeigt ein weiteres Ausführungsbeispiel eines Auslegers, bei dem der Halter 80 ähnlich dem Halter 72 an einem Arm 82 Klemmbacken 84, 86 aufweist. Die der Tragsäule zugeordnete Klemmbacke 84 ist vertikal ausgerichtet und feststehend angeordnet. Die bewegliche Klemmbacke 86 hingegen ist mittels nicht näher dargestellter Mittel betätigbar und liegt in geöffneter Stellung horizontal im Arm 82. Dadurch muss der Halter 80 mit seinem Arm 82 weniger hoch ausgefahren werden, als der Halter 72 der Figur 3, um den Rand einer Kanne zu überfahren. Dies ist insbesondere dort von Vorteil, wo der Abstand zwischen Kanne 6 und Maschinengestell 16 relativ begrenzt ist.FIG. 4 shows a further exemplary embodiment of a cantilever, in which the holder 80, similar to the holder 72, has clamping jaws 84, 86 on an arm 82. The jaw 84 assigned to the support column is oriented vertically and arranged in a fixed manner. The movable clamping jaw 86, on the other hand, can be actuated by means not shown in detail and lies horizontally in the arm 82 in the open position. As a result, the holder 80 with its arm 82 has to be extended less than the holder 72 in FIG. 3 in order to close the edge of a can run over. This is particularly advantageous where the distance between the can 6 and the machine frame 16 is relatively limited.

Wie Figur 3 zeigt, ist der Ausleger 48 mit einem auf das Gewicht der aufzunehmenden Kanne E ansprechenden Sensor 88 ausgestattet, der in nicht näher dargestellter Weise mit der zweiten Steuervorrichtung verbunden ist. Hierzu stützt sich das Schwenklager 90 der Rolle 54 an einer Feder 92 ab, die sich ihrerseits an einem Innenflansch 94 in der Tragsäule 52 abstützt. Das Schwenklager 90 ist überdies mit einer Stange 96 verbunden, die den Sensor 88 betätigt. Mit Hilfe des Sensors 88 ist es möglich, volle Kannen V von leeren Kannen L und von im Einsatz befindlichen teilweise gefüllten Kannen E zu unterscheiden.As FIG. 3 shows, the boom 48 is equipped with a sensor 88 which responds to the weight of the can E to be accommodated and which is connected in a manner not shown to the second control device. For this purpose, the pivot bearing 90 of the roller 54 is supported on a spring 92, which in turn is supported on an inner flange 94 in the support column 52. The pivot bearing 90 is also connected to a rod 96 which actuates the sensor 88. With the aid of the sensor 88, it is possible to distinguish full cans V from empty cans L and from partially filled cans E in use.

Die Funktionsweise der Anlage ist beispielsweise wie folgt.The system works as follows, for example.

Geht an einer Spinnstelle 4a der Bandvorrat in einer Kanne 6 zur Neige, so wird über einen entsprechenden Befehlsgeber 428 über die Verbindung 44 ein Signal an die Versorgungsstation 24 abgegeben. Dabei können gleichzeitig die erste und die zweite Steuervorrichtung 28, 30 des Flurförderwagens aktiviert werden. Die zweite Steuereinrichtung 30 löst dabei den ersten Ausleger 46 aus, der von einem Vorrat eine volle Kanne V aufnimmt. Nach Abschluss des Aufnahmevorganges wird die erste Steuervorrichtung 28 aktiviert und mit dem durch den Befehlsgeber 428 bestimmten Zielcode versehen. Der Flurförderwagen 22 setzt sich daraufhin längs der Leitspur 32 in Bewegung. Stellt der Flurförderwagen an der Verzweigungsstelle 34, fest, dass der Zeilcode im Streckenabschnitt 38, liegt, so schwenkt der Flurförderwagen an der Verzweigungsstelle 34, ab. Durch einfaches Abzählen der Markierungen 40, bis 408 erreicht der Flurförderwagen die Spinnstelle 48.If the supply of tapes in a can 6 is running low at a spinning station 4 a, a signal is sent to the supply station 24 via a corresponding command transmitter 42 8 via the connection 44. The first and the second control device 28, 30 of the industrial truck can be activated simultaneously. The second control device 30 triggers the first boom 46, which receives a full can V from a supply. After completion of the recording process, the first control device 28 is activated and provided with the target code determined by the command transmitter 42 8 . The industrial truck 22 then starts to move along the guide track 32. If the industrial truck at the junction 34 determines that the line code is in the route section 38, the industrial truck swivels at the junction 34. By simply counting the marks 40, to 40 8 , the industrial truck reaches the spinning position 4 8 .

Der Flurförderwagen hält derart vor der Spinnstelle 48 an, dass der dritte Ausleger 50 der vorderen in der ersten Reihe stehenden Kanne E gegenübersteht, die gerade im Einsatz ist. Das in der zweiten Steuervorrichtung vorhandene Kannenwechsel-Programm löst den Kannenwechsel aus. Der dritte Ausleger 50 erfasst nun die im Einsatz stehende Kanne E und führt sie in den Flurförderwagen (Figur 3). Dann fährt der Flurförderwagen um eine Teilung zurück, bis der zweite Ausleger 48 an der Spinnstelle 48 ansteht. Der zweite Ausleger 48 erfasst die in der zweiten Reihe 12 stehende leere Kanne L (Figur4) und führtdiese in den Flurförderwagen. Daraufhin fährt der Flurförderwagen wiederum um eine Teilung vor, bis der dritte Ausleger 50 der Spinnstelle 48 gegenübersteht. Der Ausleger 50 bringt nun die im Einsatz stehende Kanne E in die zweite Reihe 12 und setzt sie dort ab. Nach Zurücknehmen des Auslegers 50 fährt der Flurförderwagen wiederum um eine Teilung vorwärts, bis der erste Ausleger 46 der Spinnstelle 48 gegenübersteht. Der erste Ausleger 46 stellt nun die volle Kanne V in der ersten Reihe 10 vor der Spinnstelle 48 ab. Nach Zurückziehen des Auslegers 46 ist der Kannenwechselvorgang beendet und die zweite Steuervorrichtung 30 gibt der ersten Steuervorrichtung 28 den Befehl, in die Kannenabgabestation 26 zu fahren. Dort gibt der zweite Ausleger 48 die leere Kanne L an einem Stapelplatz ab. Daraufhin kann ein neuer Arbeitszyklus ausgelöst werden.The industrial truck stops in such a way in front of the spinning unit 4 to 8, that the third arm 50 of the front stationary in the first row E pot faces, which is currently in use. The can change program in the second control device triggers the can change. The third boom 50 now detects the can E in use and guides it into the industrial truck (FIG. 3). Then, the industrial truck moves back by one pitch, is present at the spinning station 4 8 to the second boom 48th The second boom 48 grasps the empty can L (FIG. 4) standing in the second row 12 and guides it into the industrial truck. Then, the industrial truck traveling in front in turn by one pitch until the third arm 50 of the spinning position opposed to 4. 8 The boom 50 now brings the can E in use into the second row 12 and sets it down there. After withdrawal of the arm 50 of the industrial truck, in turn, moves by one pitch forward until the first arm 46 of the spinning unit faces 4. 8 The first arm 46 now represents the full can V in the first row 10 from in front of the spinning unit 4. 8 After the boom 46 has been withdrawn, the can changing process is ended and the second control device 30 commands the first control device 28 to drive into the can dispensing station 26. There the second delivery 48 delivers the empty can L to a stacking place. A new work cycle can then be triggered.
