Description

Die Erfindung betrifft eine Transportvorrichtung, insbesondere zum Transportieren von Wickeln zu Kämmaschinen,mit einer Greif­einrichtung, die mittels einer Hubeinrichtung an einer Laufkat­ze einer Kranbrücke gehalten ist, die auf einer Kranbahn mit stirnseitigen Fahrwerken verfahrbar ist,die jeweils einen Fahr­motor enthalten, die von einer gemeinsamen Steuerung gesteuert sind.The invention relates to a transport device, in particular for transporting coils to combing machines, with a gripping device which is held by means of a lifting device on a trolley of a crane bridge, which can be moved on a crane runway with end trolleys, each of which contains a drive motor, which is driven by a common one Control are controlled.

Bei einer Transportvorrichtung der eingangs genannten Art kann die Kranbrücke einer relativ große Spannweite erhalten, da sie wenigstens annähernd der Länge wenigstens einer Kämmaschine entsprechen muß. Da die zu transportierenden Gegenstände, nämlich die Wickel, nur ein Gewicht von etwa 250 N aufweisen, könnte an sich die Kranbrücke relativ leicht dimensioniert werden. Dabei besteht jedoch die Gefahr von Verwindungen, ins­besondere durch nicht völliges Synchronlaufen der Fahrmotoren der beiden Fahrwerke.In the case of a transport device of the type mentioned at the outset, the crane bridge can have a relatively large span, since it must correspond at least approximately to the length of at least one combing machine. Since the objects to be transported, namely the windings, only have a weight of about 250 N, the crane bridge itself could be dimensioned relatively easily. However, there is a risk of warping, in particular due to the drive motors of the two running gears not running in complete synchronization.

Der Erfindung liegt die Aufgabe zugrunde,eine Transportvorrich­tung der eingangs genannten Art so auszubilden, daß ein Syn­chronlauf der beiden Fahrwerke gewährleistet ist.The invention has for its object to provide a transport device of the type mentioned so that synchronous operation of the two trolleys is ensured.

Diese Aufgabe wird dadurch gelöst, daß an beiden Fahrwerken Mittel zum Erfassen ihrer relativen Position auf der Kranbahn vorgesehen sind, die an die Steuerung der Fahrmotoren ange­schlossen sind, die Mittel zum Feststellen von Abweichungen zwischen den Positionen der Fahrwerke enthält und die bei fest­gestellter Abweichung durch Laufenlassen des Fahrmotors eines der beiden Fahrwerke einen Ausgleich vornimmt.This object is achieved in that means are provided on both trolleys for detecting their relative position on the crane runway, which are connected to the control of the drive motors, the means for detecting deviations contains between the positions of the trolleys and one of the two trolleys compensates for any discrepancies by letting the drive motor run.

Durch diese Ausbildung wird in einfacher Weise sichergestellt, daß die Kranbrücke bei Auftreten von Abweichungen selbsttätig Korrekturen vornimmt, so daß eine unzulässige Belastung der Kranbrücke selbst nicht auftritt. Die Kranbrücke kann deshalb leicht gebaut werden, d.h. so dimensioniert werden, wie es die Festigkeit erfordert, ohne daß eine besondere Aussteifung zum Ausgleich von Fahrwerksungenauigkeiten erforderlich ist.This design ensures in a simple manner that the crane bridge automatically makes corrections when deviations occur, so that an impermissible loading of the crane bridge itself does not occur. The crane bridge can therefore be easily built, i.e. be dimensioned as required by the strength, without a special stiffening to compensate for inaccuracies in the chassis.

In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß die Fahrwerke mit Mitteln zum Erkennen des Überfahrens jeweils einer definierten Stelle der Kranbahn ausgerüstet sind, die ein Startsignal und ein Abfragesignal an einen Zähler abgeben, der den abgefragten Wert in die Steuerung eingibt, wobei das Signal des als erstes die definierte Stelle erreichenden Fahrwerkes das Startsignal und das Signal des nachfolgenden Fahrwerkes das Abfragesignal ist, und wobei der Zähler, der an Drehzahlaufneh­mer der Fahrmotoren angeschlossen ist, die Umdrehungen des Fahrmotors des nachfolgenden Fahrwerkes zählt. Auf diese Weise wird eine einfache und genaue Erfassung von eventuell auftre­tenden Abweichungen zwischen den Fahrwerken der beiden Stirn­seiten der Kranbrücke geschaffen. Dabei ist es zweckmäßig, wenn die definierten Stellen der beiden Seiten der Kranbahn in Fahrtrichtung in einem Abstand liegen. Durch diese Maßnahme wird erreicht, daß abhängig von der Fahrtrichtung jeweils das eine Fahrwerk das Startsignal und das andere Fahrwerk das Ab­fragesignal für den Zähler gibt. Außerdem wird erreicht, daß eine ausreichende Anzahl von Zählimpulsen erhalten wird, so daß eine wirkungsvolle Überprüfung möglich ist.In a further embodiment of the invention it is provided that the trolleys are equipped with means for detecting the passage of a defined point on the crane runway, which emit a start signal and a query signal to a counter, which inputs the queried value into the control, the signal of the first the landing gear reaching the defined position is the start signal and the signal of the following landing gear is the interrogation signal, and the counter, which is connected to the speed sensor of the driving motors, counts the revolutions of the driving motor of the following landing gear. In this way, a simple and accurate detection of any deviations that occur between the trolleys of the two end faces of the crane bridge is created. It is useful if the defined points on both sides of the crane runway are at a distance in the direction of travel. This measure ensures that, depending on the direction of travel, one undercarriage gives the start signal and the other undercarriage the query signal for the counter. It is also achieved that a sufficient number of counts is obtained so that an effective check is possible.

Auf einer Kranbahn (15) ist eine Kranbrücke (14) verfahrbar, die im wesentlichen aus zwei parallelen Trägern besteht, die an ihren stirnseitigen Enden mit Fahrwerken (16, 17) versehen sind, die jeweils einen Fahrmotor (18) enthalten. Auf der Kran­brücke (14) ist eine Laufkatze (13) verfahrbar, die ebenfalls einen Antrieb enthält, der allerdings nicht dargestellt ist. An der Laufkatze (13) ist mittels einer Hubeinrichtung (12) eine Greifeinrichtung (11) aufgehängt, die zangenartige Greifelemen­te aufweist, mit denen ein Wickel (10), wie er Kämmaschinen vorgelegt wird, im Bereich einer Hülse ergriffen werden kann, auf die der Wickel (10) aufgewickelt ist.A crane bridge (14) can be moved on a crane runway (15), which essentially consists of two parallel supports, which are provided at their front ends with trolleys (16, 17), each of which contains a traction motor (18). A trolley (13) can be moved on the crane bridge (14), which also contains a drive, which is not shown, however. On the trolley (13) a gripping device (11) is suspended by means of a lifting device (12), which has pliers-like gripping elements with which a winding (10), as presented to combing machines, can be gripped in the region of a sleeve onto which the Winding (10) is wound.

Die Kranbrücke (14) einer derartigen Transportvorrichtung kann eine relativ große Spannweite aufweisen, da sie wenigstens etwa der Länge wenigstens einer Kämmaschine entsprechen muß. Diese Kämmmaschinen werden dann in einer Reihe hintereinander im Bereich unter der Kranbahn (15) aufgestellt, so daß sich die Arbeitsstellen in einer Reihe parallel zur Kranbrücke (14) erstrecken. Andererseits soll die Kranbrücke (14) möglichst leicht gebaut werden, um rasch beweglich und leicht steuerbar zu sein. Um zu erreichen, daß durch die Fahrwerke (16, 17) keine Verwindungen in die Kranbrücke (14) eingeleitet werden, sollen die beiden Fahrwerke (16, 17) möglichst synchron laufen. Die Fahrwerke (16, 17) haben nicht dargestellte Laufräder mit einem einen relativ hohen Reibwert aufweisenden Belag, bei­spielsweise einem Gummibelag. Trotzdem kann es vorkommen, daß insbesondere bei ganz am Ende der Kranbrücke (14) befindlicher Laufkatze (13) die Fahrwerke nicht völlig gleich laufen. Es wird deshalb vorgesehen, daß die Transporteinrichtung so ausgebildet ist, daß sie selbsttätig eventuell auftretende Abweichungen in dem Synchronlauf der beiden Fahrwerke (16, 17) der Kranbrücke (14) ausgleicht. An den beiden Fahrwerken (16, 17) sind Detektoren (20, 22) angebracht, beispielsweise Licht­sonden. Diesen Detektoren (20, 22) sind fest an der Kranbahn (15) angeordnete detektierbare Elemente (21,23) zugeordnet, beispielsweise Reflektoren. Beim Überfahren der Detektoren (20, 22) über die zugehörigen detektierbaren Elemente (21, 23) wird geprüft, ob die beiden Fahrwerke (16, 17) noch synchron laufen.The crane bridge (14) of such a transport device can have a relatively large span, since it must correspond at least approximately to the length of at least one combing machine. These combing machines are then installed in a row one behind the other in the area under the crane runway (15), so that the work stations extend in a row parallel to the crane bridge (14). On the other hand, the crane bridge (14) should be built as light as possible in order to be quickly movable and easy to control. In order to ensure that the trolleys (16, 17) do not introduce any twists into the crane bridge (14), the two trolleys (16, 17) should run as synchronously as possible. The trolleys (16, 17) have wheels (not shown) with a lining that has a relatively high coefficient of friction, for example a rubber lining. Nevertheless, it can happen that the trolleys do not run completely the same, especially when the trolley (13) is at the very end of the crane bridge (14). It is therefore provided that the transport device is designed so that it automatically occurs Compensates for deviations in the synchronous operation of the two trolleys (16, 17) of the crane bridge (14). Detectors (20, 22), for example light probes, are attached to the two trolleys (16, 17). These detectors (20, 22) are assigned detectable elements (21, 23) which are fixed to the crane runway (15), for example reflectors. When the detectors (20, 22) are passed over the associated detectable elements (21, 23), it is checked whether the two trolleys (16, 17) are still running synchronously.

Die Fahrmotoren (18) der Fahrwerke (16, 17) sind mit Impulse abgebenden Drehzahlaufnehmern versehen,die bei dem Ausführungs­beispiel als photoelektrische Drehzahlaufnehmer ausgebildet sind und die eine Impulsscheibe (25) und einen Sensor (26) auf­weisen. Diese Drehzahlaufnehmer (25, 26) sind an einen Zähler (24) angeschlossen. An den gleichen Zähler (24) sind auch die Detektoren (20, 22) angeschlossen, wobei das zuerst ankommende Signal der Detektoren (20, 22) den Zähler (24) startet und das nachfolgende Signal des Zähler (24) abfragt. Um definierte Ver­hältnisse zu haben, sind die detektierbaren Elemente (21, 23) in Fahrtrichtung der Kranbrücke (14) versetzt an der Kranbahn (15) angeordnet. Wenn das Ausgleichen zwischen den Fahrwerken 16, 17) nur in einer Fahrtrichtung vorgenommen wird, so er­reicht immer einer der Detektoren, bei dem Ausführungsbeispiel der Detektor (22), zuerst das ihm zugeordnete detektierbare Element (23). Dieser Detektor (22) gibt dann immer das Start­signal für den Zähler (24). Der Zähler (24) zählt dann die Im­pulse, die ihm von dem Drehzahlaufnehmer (25, 26) des nachfol­genden Fahrwerkes zugeführt werden, bei dem Ausführungsbeispiel des Fahrwerkes (17). Der Detektor (20), sobald er sein zugehö­riges detektierbares Element (21) erreicht, gibt dann das Ab­fragesignal für den Zähler (24). Der gezählt Wert der Umdrehun­gen des Fahrmotors (18) des Fahrwerkes (17) wird in einer Steu­erung (19) mit einem vorgegebenen Wert verglichen, der dem Syn­chronlauf der beiden Fahrwerke (16, 17) entspricht. Wird bei diesem Vergleich eine Abweichung festgestellt, die eine vorge­gebene Grenze überschreitet, so nimmt die Steuerung (19) eine Korrektur in der Weise vor, daß nach einem Stillsetzen der Kranbrücke (14) der Fahrmotor (18) des betreffenden Fahrwerks (16, 17) nachläuft. Dabei werden von den Drehzahlaufnehmern (25, 26) die während des Nachlaufens auftretenden Impulse auf­genommen und von dem Zähler (24) gezählt. Der Zähler (24) mel­det der Steuerung (19) zurück, wenn die synchrone Position der Fahrwerke (16, 17) wieder hergestellt ist, so daß dann auch der bis dahin nachlaufende Fahrmotor (18) abgeschaltet wird. An­schließend werden die beiden Fahrmotoren (18) beider Fahrwerke (16, 17) wieder gemeinsam gestartet.The traction motors (18) of the undercarriages (16, 17) are provided with speed sensors which emit pulses, which in the exemplary embodiment are designed as photoelectric speed sensors and which have a pulse disk (25) and a sensor (26). These speed sensors (25, 26) are connected to a counter (24). The detectors (20, 22) are also connected to the same counter (24), the signal of the detectors (20, 22) arriving first starting the counter (24) and querying the subsequent signal from the counter (24). In order to have defined conditions, the detectable elements (21, 23) are arranged offset on the crane runway (15) in the direction of travel of the crane bridge (14). If the compensation between the undercarriages 16, 17) is carried out only in one direction of travel, one of the detectors, in the exemplary embodiment the detector (22), always first reaches the detectable element (23) assigned to it. This detector (22) then always gives the start signal for the counter (24). The counter (24) then counts the pulses which are supplied to it by the speed sensor (25, 26) of the following undercarriage in the embodiment of the undercarriage (17). The detector (20), as soon as it reaches its associated detectable element (21), then issues the query signal for the counter (24). The counted value of the revolutions of the drive motor (18) of the undercarriage (17) is compared in a controller (19) with a predetermined value which corresponds to the synchronous running of the two undercarriages (16, 17). If a deviation is found in this comparison that exceeds a predetermined limit, the controller (19) takes one Correction in such a way that after the crane bridge (14) is stopped, the traction motor (18) of the relevant undercarriage (16, 17) runs on. The speed pickups (25, 26) record the pulses occurring during overrun and count them by the counter (24). The counter (24) reports back to the control (19) when the synchronous position of the undercarriages (16, 17) is restored, so that the traction motor (18) trailing until then is also switched off. Then the two traction motors (18) of both trolleys (16, 17) are started together again.

Die detektierbaren Elemente (21, 23) werden an dem Endbereich der Kranbahn (15) angebracht, in welchem die Kranbrücke (14) ihre Fahrtrichtung umkehrt. Es ist jedoch auch möglich, mehrere derartiger detektierbarer Elemente (21, 23) im Verlauf der Kranbahn (15) anzuordnen, so daß die Überprüfung des Synchron­laufs auch vorgenommen wird, wenn die Kranbrücke (14) nicht bis zum Ende der Kranbahn (15) fährt.The detectable elements (21, 23) are attached to the end region of the crane runway (15) in which the crane bridge (14) reverses its direction of travel. However, it is also possible to arrange several such detectable elements (21, 23) in the course of the crane runway (15), so that the synchronous operation is also checked if the crane bridge (14) does not travel to the end of the crane runway (15) .
