Description

Die Erfindung betrifft eine Ladevorrichtung nach dem Oberbegriff des Patentanspruches 1. Mit ihr können großen Rollenkörper o. dgl. bis zu mehreren hundert bzw. tausend Kilogramm Gewicht aus einer abgestützten Lage in eine Arbeitslage so angehoben werden, daß sie zur Entnahme des Materials, z.B. zum Abwickeln einer Materialbahn frei zugänglich sind bzw. frei drehen können. Solche Rollen können beispielsweise einen maximalen Durchmesser von über 1,5 m haben.The invention relates to a charging device according to the preamble of claim 1. With it can large reel body or the like. Up to several hundred or a thousand kilograms Weight from a supported position to a working position like this be raised so that they can be used to remove the material, e.g. are freely accessible for unwinding a material web or can rotate freely. Such roles can be one have a maximum diameter of over 1.5 m.

Mit solchen Ladevorrichtungen sollen Rollen unterschiedlichen Außendurchmessers aufgenommen werden können, wobei z.B. der minimale Rollen-Durchmesser in der Größenordnung von einem halben Meter liegen kann. Unabhängig von den Durchmesserunterschieden soll die Aufnahmeachse des Rollenträgers einfach auf die Rollenachseauszurichten sein, um die z.B. durch eien Achshülse gebildete Rollennabe in Eingriff mit dem jeweiligen Aufnahmekopf des Rollenträgers bringen zu können. Hierzu kann der Rollenträger so gesteuert sein, daß seine Aufnahmeachse über einen Ausrichtweg eine annähernd geradlinige bzw. vertikale Bewegungsbahn durchläuft, die mit derjenigen Axialebene zusammenfällt, in welcher die Rollenachsen unabhängig vom Rollen-Durchmesser liegen, wenn die Rollen in einer vorbestimmten und abgestützten Lage bereitgestellt werden.With such loading devices, roles should be different Outside diameter can be recorded, e.g. of the minimum reel diameter on the order of one half a meter. Regardless of the difference in diameter the receiving axis of the roller carrier should be simple be aligned with the roller axis in order to e.g. by egg Axle sleeve formed roller hub in engagement with the respective To bring the recording head of the roller carrier. This can the roller carrier can be controlled so that its receiving axis an approximately straight or traverses vertical trajectory that with that Axial plane coincides, in which the roller axes are independent of the roll diameter when the rolls are in a predetermined and supported location provided will.

Um auch Materialeinheiten mit maximaler Außenweite bei einer solchen Anordnung linear so in eine Ladestellung zuführen zu können, daß sie ohne eigen Querbewegung in Trageingriff mit dem Materialträger gebracht werden können, kann der Materialträger mit einem Schlitten querverfahrbar sein, jedoch ergibt sich dadurch eine aufwendige und verhältnismäßig viel Raum beanspruchende Anordnung. Desweiteren ist die Ausrichtung der Aufnahmeachse auf die jeweilige Materialachse schwierig, weil unabhängig voneinander der Schlitten quer zur vertikalen Axialebene der Materialeinheit und der Materialträger in Höhenrichtung der Materialeinheit auf deren Materialachse eingestellt werden muß.To also use material units with a maximum outside width at one such an arrangement linearly lead to a loading position can that they carry without carrying their own transverse movement can be brought to the material carrier, the material carrier be traversable with a sled, but results this creates a complex and relatively large amount of space demanding arrangement. Furthermore, the orientation of the Pick-up axis on the respective material axis difficult because independently of each other, the slide perpendicular to the vertical Axial plane of the material unit and the material carrier in Height direction of the material unit on its material axis must be set.

Durch die J-A-2 182 650 ist eine Ladevorrichtung für Papierrollen bekannt geworden, bei welcher eine ringförmige Steuerkurve mit einer Kurveneindellung vorgesehen sowie mit dem Materialträger gegenüber einem stationären Steuerläufer drehbar ist. Der Steuerläufer befindet sich sehr nahe bei der Drehachse des Materialträgers.Through J-A-2 182 650 is a loading device for paper rolls become known in which an annular control curve provided with a curve indentation as well as with the Material carrier compared to a stationary control runner is rotatable. The tax runner is very close to the Axis of rotation of the material carrier.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zu schaffen, bei welcher Nachteile bekannter Ausbildungen bzw. der beschriebenen Art vermieden sind und die insbesondere eine einfache Zuführung des Materials sowie Ausrichtung der Aufnahmeachse auf die Materialachse unabhängig davon gewährleistet, welchen Abstand die Materialachse aufgrund ihrer Außenweite von der Abstützung hat. The invention has for its object a device create the disadvantages of known training or of the type described are avoided and in particular easy feeding of material and alignment of Receiving axis on the material axis regardless of guaranteed what distance the material axis due to its Has outside width of the support.

Erfindungsgemäß sind die Merkmale nach Patentanspruch 1 vorgesehen. Sie umfassen zweckmäßig Steuermittel, welche einerseits die Aufnahmeachse des Materialträgers über denjenigen Bereich annähernd geradlinig bewegen, in welchem die Materialachsen der zu verarbeitenden Materialeinheiten liegen können und die andererseits dazu geeignet sind, die Ladevorrichtung in eine Stellung zu überführen, in welcher die jeweilige Materialeinheit unabhängig von ihrer außenweite in einer annähernd geradlinigen Längsbewegung und ohne angetriebene Querförderung so in eine stationäre Ladestellung überführt werden kann, daß sie aus dieser nur noch durch Bewegungen der Ladevorrichtung in Eingriff mit dem jeweiligen Materialträger gebracht werden kann. Die Steuermittel bewirken eine kontinuierlich geradlinige Zwangsbewegung über den Ausrichtweg, so daß es nicht erforderlich ist, zwei quer zueinander liegend und gesondert anzutreibende Bewegungen so aufeinander abzustimmen, daß die Aufnahmeachse koaxial auf die Rollenachse eingestellt werden kann.According to the invention, the features according to claim 1 intended. They expediently include tax funds which on the one hand the receiving axis of the material carrier over the one Move the area approximately in a straight line in which the Material axes of the material units to be processed lie can and on the other hand are suitable for the loading device to be transferred to a position in which the respective material unit regardless of its outside width in an almost straight longitudinal movement and without driven Cross-conveying thus transferred to a stationary loading position that they can only get out of this Movements of the loading device in engagement with the respective Material carrier can be brought. The control means effect a continuously straightforward forced movement over the Alignment path so that it is not necessary to cross two mutually lying and separately driven movements so to coordinate with each other that the receiving axis coaxially the roller axis can be adjusted.

Es ist denkbar, die Begradigung des Ausrichtweges der Aufnahmeachse durch einen entsprechend gesteuerten Antrieb zu bewirken, der in Abhängigkeit vom Hubweg z.B. nach Art einer Kurvensteuerung arbeitet und die Aufnahmeachse in die begradigte Bahn zwingt. Diese Kurvensteuerung liegt zweckmäßig in einem gegenüber dem Rollenradius bzw. Rollendurchmesser größeren Abstand von der Aufnahmeachse, so daß sie gegenüber dem stationären Sockel der Ladevorrichtung nicht bewegt zu werden braucht, um nach dem Ausrichten der Aufnahmeachse auf die Rollenachse die übrigen Funktionen der Ladevorrichtung zu ermöglichen. Desweiteren kann die Kurvensteuerung eine Steuerkurve mit daran geführtem Kurvenläufer aufweisen, welcher die Aufnahmeachse in Abhängigkeit vom Hubweg quer bewegt und dadurch die Begradigung des Ausrichtweges zwangsläufig erzwingt.It is conceivable to straighten the alignment path of the receiving axis through an appropriately controlled drive cause, depending on the stroke, e.g. sort of Curve control works and the receiving axis in the straightened Railway forces. This curve control is convenient in one compared to the roll radius or roll diameter greater distance from the receiving axis so that they are opposite the stationary base of the charging device does not move are needed to after aligning the pick axis the roller axis to the other functions of the loading device enable. Furthermore, the curve control can Have a control curve with a curve runner attached to it, which crosses the receiving axis depending on the stroke moved and inevitably the straightening of the alignment enforces.

Die erfindungsgemäße Ausbildung ist insbesondere für solche Rollenträger geeignet, die nicht linear oder über ein Parallelogrammgestänge über den Hubweg bewegt werden, sondern die nach Art einer Schwinge um eine zur Aufnahmeachse z.B. etwa parallele Schwenkachse einer Hublagerung schwenkbar sind und nach Art eines Kragarmes von der Lagerachse frei zur Aufnahmeachse ausragen. Die Aufnahmeachse führt dann bei einer Schwenkbewegung um die Schwenkachse über den dem Ausrichtweg entsprechenden Hubweg eine Bogenbahn aus, die durch die Kurvensteuerung begradigt wird. Im Falle einer Steuerkurve ist diese dann zweckmäßig entsprechend gekrümmt bzw. nicht geradlinig. Liegt die Steuerkurve auf der von der Aufnahmeachse abgekehrten Seite der Schwenkachse, ist die Steuerkurve entgegengesetzt zu derjenigen Bogenbahn gekrümmt, die die Aufnahmeachse um die Schwenkachse der Traglagerung ausführt.The training according to the invention is particularly for such Suitable for roller carriers that are not linear or via a parallelogram linkage are moved over the stroke, but the in the manner of a rocker around one to the receiving axis e.g. about parallel pivot axis of a lifting bearing are pivotable and in the manner of a cantilever from the bearing axis freely to the receiving axis protrude. The receiving axis then leads to one Swivel movement around the swivel axis over the alignment path appropriate stroke from an arc path through the Curve control is straightened. In the case of a control curve it is then appropriately curved or not straightforward. If the control curve lies on that of the receiving axis opposite side of the swivel axis is the control curve opposite to the curved path that the Execution axis around the pivot axis of the support bearing executes.

Die Hublagerung ist quer zur Aufnahmeachse gegenüber dem Vorrichtungssockel bewegbar gelagert, um die Begradigung des Ausrichtweges der Aufnahmeachse zu ermöglichen. Anstatt diese Querbeweglichkeit durch eine lineare Schlittenbewegung zu ermöglichen, ist zweckmäßig eine Schwenkbewegung um eine zur Schwenkachse bzw. zur Aufnahmeachse etwa parallel liegende Lagerachse vorgesehen, deren Abstand von der Schwenkachse wesentlich kleiner als der Abstand zwischen Schwenkachse und Aufnahmeachse sein kann. Die Schwenkachse und die Lagerachse liegen vorteilhaft annähernd vertikal übereinander, so daß sich sehr günstige Belastungsverhältnisse ergeben.The stroke bearing is transverse to the receiving axis opposite to that Device base movably mounted to straighten the To enable alignment of the receiving axis. Instead of this Lateral movement through a linear slide movement enable, is a pivotal movement to one Swivel axis or approximately parallel to the receiving axis Bearing axis provided, the distance from the pivot axis much smaller than the distance between the swivel axis and Receiving axis can be. The swivel axis and the bearing axis are advantageously approximately vertically one above the other, so that very favorable load conditions arise.

Mit den Steuermitteln bzw. der Kurvensteuerung kann auch gleichzeitig die Bewegung der Aufnahmeachse sowie deren Bahn zwischen dem Ausrichtweg und der Beschick-Stellung gesteuert werden, so daß die Aufnahmeachse über ihren gesamten Bewegungsweg kontinuierlich gesteuert werden kann, ohne daß quer zueinander liegende Bewegungen aufeinander abgestimmt werden müssen bzw. hierfür Unterbrechungen der Bewegungsabläufe erforderlich sind. Zum Beispiel kann die Steuerkurve ununterbrochen von dem dem Ausrichtweg zugehörigen Kurvenabschnitt in einen anschließenden Kurvenabschnitt übergehen, der die Bewegungsbahn bis zur Beschick-Stellung steuert.With the control means or the curve control can also at the same time the movement of the receiving axis and its path controlled between the alignment path and the loading position be so that the receiving axis over its entire path of movement can be controlled continuously without cross movements lying to each other can be coordinated interruptions in the movement sequences required are. For example, the control curve can be continuous from the curve section belonging to the alignment path pass into a subsequent curve section, which controls the movement path up to the loading position.

Für die Steuerung über den begradigten Ausrichtweg sowie für die Steuerung bis zur Beschick-Stellung genügt ein einziger Antrieb, der auch aus mehreren Antriebseinheiten, z.B. Zylindereinheiten, bestehen kann. Es ist aber auch denkbar, die Bewegungsbahn zwischen dem Ausrichtweg und der Beschick-Stellung mit einem weiteren Antrieb zu beeinflußen, der dann synchron zu demjenigen Hubantrieb arbeitet, welcher die Aufnahmeachse über den Ausrichtweg bewegt. In diesem Fall kann es ausreichend sein, die Steuerkurve nur für die Steuerung über den Hubweg vorzusehen.For control via the straightened alignment path and for the control up to the loading position is sufficient Drive that also consists of several drive units, e.g. Cylinder units can exist. But it is also conceivable the path of movement between the alignment path and the loading position to influence with another drive, which then works synchronously with the linear actuator that the Pick-up axis moved over the alignment path. In this case it may be sufficient to use the control curve only for the To provide control over the stroke.

Die Steuermittel wirken zweckmäßig auf eine Stange der Hublagerung, entlang welcher der jeweilige Rollenträger verschiebbar ist, um die Rolle in getragenem Zustand axial verstellen bzw. auf eine die Materialbahn verarbeitende Maschine ausrichten zu können. Die Kurvensteuerung führt diese Axialbewegung nicht mit aus, sondern befindet sich stationär im Bereich des jeweils zugehörigen Sockels, der in einer stationären Sockelplatte die Steuerkurve aufweisen kann.The control means act appropriately on a rod of Stroke along which the respective roller carrier is slidable axially around the roller when worn adjust or to a processing of the material web Align machine. The curve control leads this axial movement is not with, but is located stationary in the area of the associated base, which in the control curve of a stationary base plate can.

Embodiments of the invention are shown in the drawings and are explained in more detail below. The drawings show:

Die Ladevorrichtung 1 weist einen stationären Vorrichtungs-Sockel 2 und einen daran zur Ausführung von Hub- und Ausweichbewegungen bewegbar gelagerten Rollenträger 3 auf, der am Ende eines freiliegenden Tragabschnittes 4 mit einem Aufnahme- bzw. Spannkopf 6 versehen ist, welcher eine horizontale Aufnahmeachse 5 bestimmt. Als Hublagerung 7 ist ein Schwenklager mit horizontaler bzw. zur Aufnahmeachse 5 paralleler Lagerachse 8 vorgesehen, um welche der Träger 3 zur Ausführung der erforderlichen Funktionsbewegungen nur über einen Bogenwinkel von etwa 90° geschwenkt zu werden braucht.The charging device 1 has a stationary device base 2 and one for executing lifting and evasive movements movably mounted roller carrier 3 on the at the end of an exposed support section 4 with a Recording or clamping head 6 is provided, which is a horizontal Recording axis 5 determined. As a lifting bearing 7 is a Swivel bearing with horizontal axis or to the axis 5 parallel bearing axis 8 is provided, around which the carrier 3rd to perform the required functional movements only to be pivoted over an arc angle of approximately 90 ° needs.

Die Hublagerung 7 ist gegenüber dem Sockel 2 annähernd horizontal bzw. quer zur Aufnahmeachse 5 bewegbar und dafür in einer Traglagerung 9 um eine Schwenkachse 11 schwenkbar gelagert, die etwa parallel zur Achse 5 bzw. 8 sowie mit der Lagerachse 8 in einer etwa vertikalen Axialebene liegt. Der maximal erforderliche Schwenkwinkel für die Hublagerung 7 beträgt nur wenige Winkelgrade, nämlich weniger als 10 bzw. 5°, wobei der Abstand zwischen den Achsen 8, 11 kleiner als die Hälfte des Abstandes zwischen den Achsen 5, 8 oder etwa ein Drittel davon sein kann. Dadurch kann die Hublagerung 7 bzw. der Tragabschnitt 4 mit dem Spannkopf 6 eine seiner Hubbewegung synchron überlagerte Quer- bzw. Horizontalbewegung derart ausführen, daß die Aufnahmeachse 5 statt einer reinen Bogenbahn um die Lagerachse 8 über einen vorbestimmten Schwenkwinkel eine annähernd geradlinige bzw. vertikale Bewegung ausführt. Dieser Schwenkwinkel liegt zweckmäßig unter 60 bzw. 45° und in der Größenordnung von 30°. Das Traglager der Traglagerung 7 hängt an einem gegenüber seiner Außenweite schmaleren und starr mit ihm verbundenen Traglenker 12, der mit seinem oberen Ende um die Schwenkachse 11 schwenkbar gelagert ist.The stroke bearing 7 is approximately opposite the base 2 movable horizontally or transversely to the receiving axis 5 and therefor in a support bearing 9 pivotable about a pivot axis 11 stored approximately parallel to axis 5 or 8 and with the Bearing axis 8 lies in an approximately vertical axial plane. Of the Maximum swivel angle required for the stroke bearing 7 is only a few degrees, namely less than 10 or 5 °, the distance between the axes 8, 11 smaller than half the distance between axes 5, 8 or about can be a third of it. As a result, the stroke bearing 7 or the support section 4 with one of the clamping head 6 Lifting movement synchronously superimposed transverse or horizontal movement execute such that the receiving axis 5 instead of one pure arc path around the bearing axis 8 over a predetermined Swivel angle an approximately straight or vertical Movement. This swivel angle is appropriate below 60 or 45 ° and in the order of 30 °. The Support bearing of the support bearing 7 depends on one of his Outer width narrower and rigidly connected to the control link 12, which has its upper end about the pivot axis 11 is pivotally mounted.

Zur kontinuierlich durchgehenden Bewegung des Tragabschnittes 4 über die begradigte Bewegungsbahn sowie darüberhinaus sind Steuermittel 10 vorgesehen, die im wesentlichen vollständig auf der von der Aufnahmeachse 5 abgekehrten Seite der Achsen 8, 11 bzw. der Hublagerung 7 und der Traglagerung 9 im wesentlichen in gleicher Höhe wie die begradigte Bewegungsbahn liegen. Auf der vom Träger 3 abgekehrten Seite steht ein mit diesem drehschlüssig verbundener Steuerarm 13 über die Lagerachse 8 vor, mit welchem einerseits der Spannkopf 6, der Tragabschnitt 4 bzw. der gesamte Träger 3 in seiner Längsrichtung bzw. etwa in Richtung der Verbindungsgeraden zwischen den Achsen 5, 8 bewegt, nämlich um die Schwenkachse 11 geschwenkt werden kann und mit dem andererseits der Spannkopf 6 mit dem Träger 3 in Höhenrichtung bzw. um die Lagerachse 8 zu bewegen ist. Durch die beschriebene Ausbildung braucht der Spannkopf 6 bzw. der Tragabschnitt 4 nicht gegenüber dem übrigen Träger 3 in dessen Längsrichtung verstellbar zu sein, sondern der gesamte Träger 3 führt die Bewegung aus, die zur Begradigung der ansonsten um die Lagerachse 8 gekrümmten Bewegungsbahn erforderlich ist.For continuous movement of the support section 4 are about the straightened trajectory and beyond Control means 10 are provided which are substantially complete on the side of the axes facing away from the receiving axis 5 8, 11 or the lifting bearing 7 and the support bearing 9 in essentially at the same height as the straightened trajectory lie. On the side facing away from the carrier 3 is a with this rotationally connected control arm 13 via the Bearing axis 8 in front, with which the clamping head 6, on the one hand Support section 4 or the entire carrier 3 in its longitudinal direction or approximately in the direction of the connecting straight line between the axes 5, 8 moves, namely about the pivot axis 11 can be pivoted and with the other hand the clamping head 6 with the carrier 3 in the height direction or around the bearing axis 8 is to be moved. Due to the training described Clamping head 6 and the support section 4 are not opposite remaining carrier 3 to be adjustable in its longitudinal direction, but the entire carrier 3 executes the movement that to Straightening otherwise curved around the bearing axis 8 Trajectory is required.

Die Steuermittel 10 weisen eine unmittelbar auf den Steuerarm 13 wirkende Kurvensteuerung 14 auf, welche zwangsgesteuert zu einer Bewegung der aus Träger 3 und Hublagerung 7 bestehenden Trageinheit um die Schwenkachse 11 führt und zwar wegabhängig vom Hub- bzw. Schwenkweg des Trägers 3 um die Lagerachse 8. Zu diesem Zweck läuft ein Läufer 16 an einer Steuerkurve 15, die zweckmäßig feststehend am Sockel 2 angeordnet ist, so daß der Steuerarm 13 an seinem von der Achse 8 entfernten Ende lediglich mit dem Läufer 16, z.B. einer Rolle, versehen zu sein braucht und mit diesem Läufer 16 in die Steuerkurve 15 formschlüssig eingreift. Die Steuerkurve 15 kann den Läufer 16 zwischen einander gegenüberliegenden und etwa parallelen Kurvenflanken aufnehmen, so daß der Träger 3 in beiden entgegengesetzten Richtungen um die Schwenkachse 11 zwangsläufig gesteuert ist. Der Läufer 16 liegt zweckmäßig etwa in einer gemeinsamen Axialebene mit den Achsen 5, 8. Die Steuerkurve 15 erstreckt sich nach oben und unten über die Höhe der Lagerachse 8 hinaus und ist im wesentlichen über ihre gesamte Erstreckung gekrümmt.The control means 10 point directly to the control arm 13 acting cam control 14, which is positively controlled a movement of the existing from carrier 3 and 7 lifting Carries the unit about the pivot axis 11, depending on the path from the stroke or swivel path of the carrier 3 about the bearing axis 8. For this purpose, a runner 16 runs on a control cam 15, which is suitably fixed on the base 2, so that the control arm 13 at its end remote from the axis 8 only with rotor 16, e.g. a role, provided to needs to be and with this rotor 16 in the control curve 15 intervenes positively. The control curve 15 can the runner 16 between opposite and approximately parallel Record flanks so that the carrier 3 in both opposite directions about the pivot axis 11 inevitably is controlled. The runner 16 is expedient approximately in a common axial plane with axes 5, 8. The control curve 15 extends up and down the height of the Bearing axis 8 and is essentially over its entire Extension curved.

Ein bis zu einem oberen Ende der Steuerkurve 15 reichender Kurvenabschnitt 17 dient zur genannten Begradigung der Bewegungsbahn sowie zur Anschlagbegrenzung des Trägers 3 in seiner untersten Stellung. Ein ununterbrochen an das untere Ende des Kurvenabschnittes 17 anschließender und längerer Kurvenabschnitt 18 der Steuerkurve 15 dient dazu, den Träger 3 bei Bewegungen über das obere Ende der begradigten Bewegungsbahn hinaus so zu führen, daß praktisch keine Bewegungen um die Schwenkachse 11 stattfinden, sondern die Hublagerung 7 in derjenigen Stellung gesichert ist, die sie einnimmt, wenn sich die Aufnahmeachse 5 etwa am oberen bzw. unteren Ende der begradigten Bewegungsbahn befindet. Das zugehörige Ende der gesamten Bewegungsbahn des Trägers 3 ist ebenfalls dadurch anschlagbegrenzt, daß der Läufer 16 auf das Ende des Kurvenabschnittes 18 auf läuft. Da der Abstand des Läufer 16 von der Lagerachse 8 etwa um die Hälfte kleiner als der Abstand zwischen dieser Lagerachse 8 und der Aufnahmeachse 5 ist, ist die Bewegungsbahn des Läufers 16 bzw. die Länge des Kurvenabschnittes 17 entsprechend kürzer als die begradigte Bewegungsbahn der Aufnahmeachse 5, so daß sich hier ein untersetzungsverhältnis sowie eine sehr kompakte Bauweise ergibt. Wie der Kurvenabschnitt 17 ist auch der Kurvenabschnitt 18 annähernd teilkreisförmig gekrümmt, jedoch mit einem wesentlich größeren, seinem Abstand von der Lagerachse 8 entsprechenden Krümmungsradius, während der Krümmungsradius des Kurvenabschnittes 17 kleiner als sein Abstand von der Lagerachse 8 ist.One reaching to an upper end of the control curve 15 Curve section 17 serves to straighten the Trajectory and limit stop of the carrier 3 in its lowest position. One continuously to the lower one End of the curve section 17 subsequent and longer Curve section 18 of the control curve 15 serves the carrier 3 for movements over the upper end of the straightened trajectory out so that practically no movements take place about the pivot axis 11, but the stroke bearing 7 is secured in the position it occupies, if the receiving axis 5 is approximately at the upper or lower end of the straightened trajectory. The associated end of the entire path of movement of the carrier 3 is also limited by the fact that the rotor 16 on the End of the curve section 18 runs on. Since the distance of the Runner 16 from the bearing axis 8 about half smaller than the distance between this bearing axis 8 and the receiving axis 5 is the path of movement of the rotor 16 or Length of the curve section 17 correspondingly shorter than that straightened trajectory of the receiving axis 5, so that here a reduction ratio and a very compact one Construction results. Like the curve section 17, the Curve section 18 curved approximately in the shape of a partial circle, however with a much larger distance from the bearing axis 8 corresponding radius of curvature, while the radius of curvature of the curve section 17 smaller than its distance from the bearing axis 8.

Etwa in der Mitte zwischen dem Läufer 16 und der Hublagerung 7 greift am Steuerarm 13 ein Hubantrieb 19 in einem Bereich an, der von der Lagerachse 8 einen größeren Abstand hat als vom Läufer 16. Mit dem Hubantrieb 19 wird der Träger 3 in seiner Bewegungsbahn bewegt und gleichzeitig der Läufer 16 entlang der Steuerkurve 15 geführt. Der Hubantrieb 19 greift nach Art eines Linearantriebes mit einer Schubstange unmittelbar am Steuerarm 13 so an, daß er sowohl die Schwenkbewegung um die Lagerachse 8 als auch diejenige um die Schwenkachse 11 antreibt.Approximately in the middle between the rotor 16 and the stroke bearing 7 a lifting drive 19 engages on the control arm 13 in one area on, which has a greater distance than the bearing axis 8 from the rotor 16. With the lifting drive 19, the carrier 3 in its trajectory moves and at the same time the rotor 16 guided along the control curve 15. The stroke drive 19 engages in the manner of a linear drive with a push rod directly on the control arm 13 so that it both the pivoting movement around the bearing axis 8 and that around the pivot axis 11 drives.

Die Rollen 21, 22 werden der Ladevorrichtung 1 über eine Rollen-Abstützung 20 zugeführt, deren stumpfwinklig prismenförmige Auflagerfläche für den Außenumfang der Rolle 21, 22 bewirkt, daß die Rollenachsen parallel zur Abstützebene bzw. horizontal stets dieselbe Lage gegenüber dem Sockel 2 einnehmen, unabhängig davon, welchen Abstand die Rollenachsen aufgrund der unterschiedlichen Rollendurchmesser von der Abstützung haben. Bei größtmöglichem Durchmesser der Rolle 21 ergibt sich die maximale Achshöhe 23 und bei kleinstem Durchmesser der Rolle 22 die minimale Achshöhe 24, wobei die maximale Achshöhe etwa zwei bis dreifach größer als die minimale Achshöhe 24 sein kann. Der Abstand zwischen den beiden Achshöhen 23, 24 bestimmt die genannte begradigte Bewegungsbahn, nämlich den Ausrichtweg 25, über welchen der Spannkopf 6 auch mit jeder beliebigen Zwischengröße von Rollen in Eingriff zu bringen sein soll. Dieser Ausrichtweg 25 ist durch den Kurvenabschnitt 17 bzw. durch eine mit der Schwenkbewegung um die Lagerachse 8 simultane Schwenkbewegung um die Schwenkachse 11 so begradigt, daß er vertikal über der Längsmittelebene der Abstützung 20 liegt.The rollers 21, 22 are the loading device 1 via a Roller support 20 supplied, the obtuse prismatic Support surface for the outer circumference of the roller 21, 22 causes the roller axes to run parallel to the support plane or always take the same position horizontally in relation to the base 2, regardless of the distance between the roller axes due to the different roll diameters from the Have support. With the largest possible diameter of the roller 21 the maximum axle height is 23 and the smallest Diameter of the roller 22, the minimum shaft height 24, the maximum shaft height about two to three times larger than that minimum shaft height can be 24. The distance between the the two straightened heights 23, 24 determine the straightened Path of movement, namely the alignment 25, via which the Clamping head 6 also with any intermediate size Roles should be brought into engagement. This alignment path 25 is through the curve section 17 or through one with the Swiveling movement around the bearing axis 8 simultaneous swiveling movement straightened about the pivot axis 11 so that it is vertically above the longitudinal center plane of the support 20.

Die Abstützung 20 ist durch einen Rollen- bzw. Unterflurförderer gebildet, welcher die Abstützung 20 mit der jeweils zentriert auf ihr liegenden Rolle 21, 22 parallel zur Rollenachse bzw. zur Aufnahmeachse 5 von außen in den Arbeitsbereich der Träger 3 fördert. Um dabei insbesondere größere Rollen 21 am jeweils in Förderrichtung ersten Träger 3 ungehindert vorbei und in eine Lage zwischen die einander gegenüber liegenden Träger 3 überführen zu können, sind die Träger 3 vom oberen Ende des Ausrichtweges 25 nach oben und hinten weiter in eine Beschickstellung 26 zu überführen, in welcher sie und alle übrigen vorrichtungsteile - parallel zur Aufnahmeachse 5 gesehen - außerhalb des Außenumfanges der größtmöglichen Rolle 21 liegen, wenn diese auf der Abstützung 20 abgestützt ist. Dadurch ist ein völlig freier Rolleneingang 27 gebildet.The support 20 is by a roller or underfloor conveyor formed, which the support 20 with each centered on her lying roller 21, 22 parallel to the roller axis or to the receiving axis 5 from the outside in the work area the carrier 3 promotes. To make it bigger in particular Rollers 21 on the respective first carrier 3 in the conveying direction passing freely and in a position between each other to be able to transfer opposite carrier 3 are the Carrier 3 from the upper end of the alignment path 25 upwards and to be transferred further into a loading position 26 in the rear which you and all other parts of the device - parallel to Receiving axis 5 seen - outside the outer circumference of the largest possible roll 21, if this is on the support 20 is supported. This gives a completely free role entrance 27 formed.

Die Bewegungsbahn vom oberen Ende des Ausrichtweges 25 bis zur Stellung 26 ist eine vom Kurvenabschnitt 18 gesteuerte, annähernd teilkreisförmige Bogenbahn, die unter einem nur um wenige Winkelgrade von 180° abweichenden stumpfen Winkel an den Ausrichtweg 25 anschließt und deren Bogenwinkel kleiner als 90° sein kann. Sobald die Rolle 21 zwischen den Ebenen der Träger 3 liegt, können diese wieder zurückgeschwenkt werden, so daß der jeweilige Spannkopf 6 vom Außenumfang der Rolle 21 her unbehindert entlang von deren zugehörigen stirnfläche in eine Lage bewegt wird, in welcher seine Aufnahmeachse 5 etwa achsgleich zur Rollenachse liegt. Die Träger 3 bzw. die Spannköpfe 6 werden dann soweit aufeinanderzu bewegt, daß sie in die Nabenöffnung der Rolle 21 bzw. 22 eingreifen und dadurch formschlüssig mit der Rolle verbunden sind. Danach werden die Träger 3 durch den Hubantrieb 19 wieder nach oben bis in eine Abrollage geschwenkt, in welcher die Materialbahn vom Außenumfang der Rolle 21 zur Verarbeitung abgezogen werden kann. Die Abrollage kann mit der Beschick-Stellung 26 zusammenfallen oder zwischen dieser und dem oberen Ende des .Ausrichtweges 25 liegen.The movement path from the upper end of the alignment path 25 to to position 26 is a controlled by curve section 18, approximately part-circular arc path, which is only under one a few degrees of obtuse angles deviating from 180 ° connects the alignment 25 and their arc angle smaller can be as 90 °. Once the roll 21 between levels the carrier 3 lies, they can be pivoted back again be so that the respective clamping head 6 from the outer circumference of the Roll 21 forth along freely from their associated face is moved into a position in which its Pickup axis 5 is approximately the same axis as the roller axis. The Carrier 3 or the clamping heads 6 are then so far towards each other moved that they into the hub opening of the roller 21 or 22 engage and thereby positively connected to the role are. Thereafter, the carrier 3 by the lifting drive 19th again pivoted up to a rolling position in which the material web from the outer circumference of the roll 21 for processing can be deducted. The rolling position can be done with the Feed position 26 coincide or between this and the upper end of the alignment path 25.

In Seitenansicht ist der jeweilige Sockel 2 winkelförmig mit einem aufrechten Winkelschenkel 28 und einem an dessen unteres Ende anschließenden, etwa horizontalen Winkelschenkel 29, welcher in Richtung zur Abstützung 20 frei ausragt. Die beiden Träger 3 sind auf einer in der Lagerachse 8 liegenden gemeinsamen Tragwelle 30 drehschlüssig, jedoch stufenlos längsverschiebbar angeordnet und weisen hierfür am hinteren Ende des Trägers 3 jeweils eine die Tragwelle 30 umgebende Tragnabe 31 auf, die im Abstand zur Innenseite des zugehörigen Sockels 2 liegt. Die Tragwelle 30 durchsetzt die einspringende Ecke zwischen den beiden Sockelschenkeln 28, 29 des zugehörigen Sockels 2 und liegt einschließlich der Hublagerung 7 unterhalb des oberen Endes des Sockelschenkels 28 sowie hinter dem vorderen Ende des Sockelschenkels 29.In side view, the respective base 2 is angular with an upright angle leg 28 and one on the latter adjoining lower end, approximately horizontal angle leg 29, which projects freely in the direction of the support 20. The two carriers 3 are on one lying in the bearing axis 8 common support shaft 30 rotatably, but continuously arranged longitudinally displaceable and have this for the rear End of the carrier 3 each surrounding the support shaft 30 Support hub 31 on the distance to the inside of the associated Socket 2 lies. The support shaft 30 passes through the re-entering Corner between the two base legs 28, 29 the associated base 2 and lies including the Stroke 7 below the upper end of the base leg 28 and behind the front end of the base leg 29.

Die Hublagerung 7 weist eine die Tragwelle 30 umgebende Lager-Außennabe 32 auf, welche benachbart zur Außenseite des zugehörigen Trägers 3 in der einspringenden Ecke zwischen den Sockelschenkeln 28, 29 liegt und von deren Oberseite der formsteif mit ihr verbundene Traglenker 12 nach oben absteht.The stroke bearing 7 has a support shaft 30 surrounding it Bearing outer hub 32, which is adjacent to the outside of the associated carrier 3 in the recessed corner between the Base legs 28, 29 and from the top of the Rigidly connected support arm 12 protrudes upwards.

Dieser Traglenker 12 ist zwischen zwei Tragarmen 34 um die Schwenkachse 11 schwenkbar gelagert, die vom oberen Ende des Sockelschenkels 28 etwa parallel zum Träger 3 frei so ausragen, daß die Hublagerung 7 mit der Tragwelle 30 um wenige Winkelgrade gegenüber dem Sockel 2 berührungsfrei um die Schwenkachse 11 schwingen kann. Die Tragwelle 30 ist in der Außennabe 32 frei drehbar.This support arm 12 is between two support arms 34 around the Pivot axis 11 pivotally mounted, which is from the upper end of The base leg 28 protrudes freely approximately parallel to the support 3, that the stroke bearing 7 with the support shaft 30 by a few Angle degrees in relation to the base 2 without contact around the Swing axis 11 can swing. The support shaft 30 is in the Outer hub 32 freely rotatable.

Mit geringem Abstand benachbart zur Außenseite der Hublagerung 7 ist auf dem zugehörigen Ende der Tragwelle 30 eine Steuernabe 33 drehschlüssig und axial gesichert angeordnet, welche den Steuerarm 13 trägt und in Draufsicht gemäß Figur 2 den Sockel 2 übergreift.A short distance away from the outside of the lifting bearing 7 is on the associated end of the support shaft 30 Control hub 33 arranged in a rotationally locking and axially secured manner, which carries the control arm 13 and in plan view according to FIG. 2 engages over the base 2.

Am unteren Ende des Sockelschenkels 28 ist ein Zylinder 35 des Hubantriebes 19 mit einer Antriebslagerung 36 um eine zu den Achsen 5, 8, 11 etwa parallele Achse schwenkbar gelagert, die im Bereich des unteren Endes des aufrechtstehenden Zylinders 35 liegt. Das Ende der hängend angeordneten Kolbenstange des Zylinders 35 ist über ein Verbindungsgelenk 37 gelenkig mit dem Steuerarm 13 verbunden. Bei Lage des Läufers 16 etwa im übergangsbereich zwischen den Kurvenabschnitten 17, 18 liegt die Mittelachse des Hubantriebes 19 etwa rechtwinklig zur Axialebene des Läufers 16 und der Lagerachse 8, so daß sich günstige Kräfteverhältnisse ergeben. Die Steuerkurve 15 erstreckt sich annähernd über die gesamte Höhe des Sockelschenkels 28 und reicht mit ihrem unteren Ende noch bis in den Bereich des Sockelschenkels 29. Sie kann durch eine von gegenüberstehenden Flanken und einer Bodenfläche begrenzte und daher nur entlang einer Nutöffnung offene Nut an der Außenseite einer stehenden Platte des Sockels 2 gebildet sein, wobei mit Abstand zur Außenseite dieser Platte eine weitere Platte des Sockels 2 vorgesehen ist und der Hubantrieb 19 sowie der Steuerarm 13 zwischen diese beiden Platten eingreift. Dadurch können die Steuermittel 10 gehäuseartig verkapselt bzw. geschützt angeordnet werden.At the lower end of the base leg 28 is a cylinder 35 of the linear actuator 19 with a drive bearing 36 to one axes 5, 8, 11 pivoted approximately parallel axis, those in the area of the lower end of the upright Cylinder 35 lies. The end of the hanging piston rod of the cylinder 35 is via a connecting joint 37 hinged to the control arm 13. With the position of the runner 16 approximately in the transition area between the curve sections 17, 18, the central axis of the linear actuator 19 is approximately at right angles to the axial plane of the rotor 16 and the bearing axis 8, so that there are favorable power relations. The control curve 15 extends approximately over the entire height of the Base leg 28 and extends with its lower end in the area of the base leg 29. You can by a bounded by opposing flanks and a floor area and therefore only open on the groove along a groove opening Formed outside of a standing plate of the base 2 be, with a distance to the outside of this plate further plate of the base 2 is provided and the linear actuator 19 and the control arm 13 between these two plates intervenes. As a result, the control means 10 can be housing-like encapsulated or protected.

Die beiden Träger 3 sind mit einer Längsverstellung 38 entgegengesetzt und/oder in gleicher Richtung synchron auf der Tragwelle 30 verschiebbar. Zwischen der Außennabe 32 und der Trägernabe 31 ist auf der Tragwelle 30 eine Lagernabe 39 drehschlüssig, jedoch axial gesichert so angeordnet, daß sie unmittelbar benachbart zur Innenseite der Außennabe 32 liegt. Von dieser Lagernabe 39 stehen schräg nach oben und vorne zwei Tragarme 41 ab, zwischen denen ein Antrieb 40, z.B. ein Getriebe- bzw. Winkelmotor, befestigt ist und an denen eine bei der Stellung der Träger 3 gemäß Figur 1 etwa in Höhe der Schwenkachse 11 liegende Stellspindel 42 drehbar gelagert ist. Der oberhalb des Trägers 3 liegende Antrieb 40 dient zum stufenlosen Antrieb der Spindel 42 und schwenkt mit dem Träger 3 um die Lagerachse 8 sowie um die Schwenkachse 11, wobei er in den Ladestellungen vor und in der BeschickStellung hinter der Schwenkachse 11 liegt. An der Oberseite des Trägers 3 und/oder der Trägernabe 31 ist eine Spindelmutter 43 o. dgl. vorgesehen, in welche die Spindel 42 so eingreift, daß Drehbewegungen der Gewindespindel 42 zu Längsverschiebungen der Träger 3 führen. Dadurch können die Träger 3 außer für ihre Eingriffsbewegung zum Eingriff in die jeweilige Rolle 21 bzw. 22 auch auf unterschiedliche Rollenlängen sowie so eingestellt werden, daß die jeweils von ihnen getragene Rolle im Bereich unterschiedlicher Längsabschnitte der gegenüber ihr wesentlich längeren Tragwelle 30 liegt. Die Verstellbarkeit ist unabhängig von der Stellung des Trägers 3 möglich.The two supports 3 are with a longitudinal adjustment 38 opposite and / or synchronously in the same direction the support shaft 30 slidably. Between the outer hub 32 and the carrier hub 31 is a bearing hub 39 on the support shaft 30 rotatably but axially secured so that they is immediately adjacent to the inside of the outer hub 32. From this bearing hub 39 are obliquely upwards and forwards two support arms 41, between which a drive 40, e.g. a Gear or angle motor, is attached and on which one in the position of the carrier 3 according to FIG Adjusting spindle 42 lying pivot axis 11 rotatably mounted is. The drive 40 located above the carrier 3 is used for stepless drive of the spindle 42 and swivels with it Carrier 3 about the bearing axis 8 and about the pivot axis 11, being in the loading positions before and in the loading position lies behind the pivot axis 11. At the top of the Carrier 3 and / or the carrier hub 31 is a spindle nut 43 or the like. In which the spindle 42 engages in such a way that rotational movements of the threaded spindle 42 to longitudinal displacements the carrier 3 lead. This allows the carrier 3 except for their engagement movement to engage in the respective Roll 21 or 22 also on different roll lengths as well be adjusted so that the one you wear Role in the area of different longitudinal sections of the compared to her much longer support shaft 30. The Adjustability is independent of the position of the carrier 3 possible.

Zur Aufnahme einer Rolle 21 bzw. 22 werden die Träger 3 in die Beschickstellung 26 überführt und die Rolle wird mit der Abstützung 20 parallel zur Aufnahmeachse 5 in den Bereich zwischen die hochgeschwenkten Träger 3 gefahren. Danach werden die Träger 3 abgesenkt und durch Axialbewegung ihre Spannköpfe 6 in Eingriff mit der Rolle gebracht. Während der Bewegung der Aufnahmeachse 5 über den Bereich zwischen den Achshöhen 23, 24 wird die Bogenbahn um die Lagerachse 8 durch den Kurvenabschnitt 17 zwangsläufig bzw. formschlüssig wirkend begradigt, so daß die Aufnahmeachse 5 über den vertikalen Ausrichtweg 25 läuft. Wird die Rolle über das obere Ende des Ausrichtweges 25 hinaus nach oben angehoben, so ist dann der Kurvenabschnitt 18 wirksam, welcher die Aufnahmeachse 5 bis zur aufrecht nach oben ragenden Beschick-Stellung 26 des Trägers '3 entlang eine Kreisbahn bewegt. Da die Hublagerung 7 des Trägers 3 in diesem Fall an der Traglagerung 9 hängt, wird die Gewichtskraft der Rolle nicht oder nur unwesentlich auf die Kurvensteuerung 14 übertragen, die in diesem Fall lediglich die Hublagerung 7 daran hindert, um die Traglagerung 9 Schwenk- bzw. Spielbewegungen auszuführen. Entsprechend umgekehrt erfolgt das Absenken und Absetzen einer auszuspannenden Rolle auf der Abstützung 20.For receiving a roll 21 or 22, the carrier 3 in the loading position 26 transferred and the role with the Support 20 parallel to the receiving axis 5 in the area drove between the pivoted carrier 3. After that the carriers 3 are lowered and their axial movement Clamping heads 6 brought into engagement with the roller. During the Movement of the receiving axis 5 over the area between the Axle heights 23, 24, the arc path through the bearing axis 8 through the curve section 17 inevitably or positively acting straightened so that the receiving axis 5 over the vertical alignment 25 runs. Will the role about that the upper end of the alignment path 25 raised upwards, then the curve section 18 is effective, which the Pick-up axis 5 up to the upright loading position 26 of the carrier '3 moves along a circular path. There the stroke bearing 7 of the carrier 3 in this case on the support bearing 9 depends, the weight of the roll is not or only insignificantly transferred to the cam controller 14, the in this case, only the stroke bearing 7 prevents the support bearing 9 swivel or play movements. Conversely, the lowering and lowering takes place a roll to be unclamped on the support 20.

In den Figuren 3 und 4 sind für einander entsprechende Teile die gleichen Bezugszeichen wie in den Figuren 1 und 2, jedoch mit unterschiedlichen Buchstabenindizes verwendet.In Figures 3 and 4 are corresponding parts for each other the same reference numerals as in Figures 1 and 2, however used with different letter indices.

Gemäß Figur 3 liegt die Lagerachse 8 über den Ausrichtweg etwa vertikal oberhalb der Schwenkachse 11, so daß der Traglenker 12a annähernd vertikal stehend vorgesehen ist. Der Hubantrieb 19a greift an einem vom steuerarm 13a gesonderten Antriebsarm 44 an, welcher mit einer von der Steuernabe gesonderten Nabe bzw. mit der Lagernabe 39a an der Innenseite des Traglenkers 12a auf der Tragwelle angeordnet ist. Der Traglenker 12a ragt wie der Hubantrieb 19a über die Oberseite des verhältnismäßig niedrigen Sockels 2a vor, wobei der nach oben zum Verbindungsgelenk 37a ausragende Hubantrieb 19a vor dem Traglenker 12a liegt und in jeder Stellung des Trägers 3a etwa Parallel zum Traglenker 12a vorgesehen ist. Oberhalb des Verbindungsgelenkes 37a ist an dem Antriebsarm 44 der Antrieb 40a der Längsverstellung gelagert. Die Kurvensteuerung 14a ist hier an einem vom Sockel 2a gesonderten Ständer 28a vorgesehen, der im Abstand hinter dem Sockel 2a liegt und dessen Steuerkurve 15a so vorgesehen ist, daß ihre Enden annähernd vertikal übereinander liegen. Der Kurvenabschnitt 18a ist dabei so gewählt, daß die Bewegungsbahn der Aufnahmeachse 5a vom oberen Ende des Ausrichtweges bis zur Beschick-Stellung gegenüber einer reinen Kreisbewegung um die feststehende Lagerachse 8a wesentlich abgeflacht wird, weil nämlich während dieser Bewegung die Lagerachse 8a nach hinten geschwenkt wird, bis in der Beschick-Stellung 26a die Axialebene der Achsen 8a, 11a etwa um 45° nach hinten zum Ständer 28a geneigt ist und die 'Lagerachse 8a wesentlich tiefer als während der Bewegungsbahn über den Ausrichtweg liegt.According to Figure 3, the bearing axis 8 lies over the alignment approximately vertically above the pivot axis 11, so that the Support arm 12a is provided approximately vertically standing. Of the Lift drive 19a engages on a separate one from the control arm 13a Drive arm 44, which with one of the control hub separate hub or with the bearing hub 39a on the inside of the support arm 12a is arranged on the support shaft. Of the Traglenker 12a protrudes like the lifting drive 19a over the top of the relatively low base 2a before, the after Lift drive 19a protruding above the connecting joint 37a the support arm 12a and in any position of the carrier 3a approximately parallel to the support arm 12a is provided. Above the Connecting joint 37a is the drive on the drive arm 44 40a of the longitudinal adjustment. The cam controller 14a is here on a stand 28a separate from the base 2a provided, which is at a distance behind the base 2a and whose control curve 15a is provided so that its ends are approximately vertically one above the other. The curve section 18a is chosen so that the path of movement of the receiving axis 5a from the upper end of the alignment path to the loading position compared to a pure circular movement around the fixed one Bearing axis 8a is substantially flattened because namely during this movement the bearing axis 8a to the rear is pivoted until the axial plane in the loading position 26a the axes 8a, 11a about 45 ° backwards to the stand 28a is inclined and the 'bearing axis 8a is substantially lower than lies over the alignment path during the movement path.

In Figur 3 ist der Förderer 45 für die Abstützung 20a näher dargestellt. Er weist angetriebene Rollenwagen auf, welche einzelne hintereinander liegende und im wesentlichen gleiche Segmente der Abstützung 20a an ihren Oberseiten tragen.In Figure 3, the conveyor 45 for the support 20a is closer shown. It has driven roller carriages, which individual ones lying one behind the other and essentially the same Wear segments of the support 20a on their tops.

Eine ähnliche Anordnung und Bewegungsbahn ist auch bei der Ausbildung nach Figur 4 vorgesehen jedoch weist hier die Steuerkurve 15b nur den Kurvenabschnitt 17b für den Ausrichtweg auf, während der übrige Bewegungsweg durch eine Kurvensteuerung bestimmt ist, die von einem Antrieb 18b bewirkt wird. Dieser, z.B. als Zylinderantrieb ausgebildete Steuerantrieb 18b verschwenkt den Traglenker 12b gegenüber dem Sockel 2b in etwa gleicher Weise wie der Kurvenabschnitt 18b gemäß Figur 3, und zwar simultan mit der Bewegung des Trägers 3b durch den Hubantrieb 19b und/oder gesondert davon. Während dieser Bewegung hebt der Läufer 16b von der Steuerkurve 15b vollständig ab, so daß die Steuerkurve 15b dann nicht wirksam ist. Zu diesem Zweck ist hier der Kurvenabschnitt 17b nicht durch eine Nut, sondern nur durch eine einzige konvexe Umfangskurve bzw. Kurvenflanke gebildet, gegen die der Läufer 16b durch den Steuerantrieb 18b über den Ausrichtweg angelegt und von der der Läufer 16b über den restlichen Bewegungsweg durch den Steuerantrieb 18b sowie durch den Hubantrieb 19b abgehoben wird. Auch der Steuerantrieb 18b kann im wesentlichen vor dem Traglenker liegen und sich in Seitenansicht gemäß Figur 4 mit dem Hubantrieb 19b dadurch kreuzen, daß er vom vorderen Ende des Sockels 2b nach oben und hinten geneigt ist. In der Beschickstellung ist der Steuerantrieb 18b dadurch flacher nach hinten geneigt als in der dem Ausrichtweg zugehörigen Stellung, so daß er den Einschub der Rollen entlang der Abstützung 20b in keiner Weise behindert. In entsprechender Weise ist auch der Hubantrieb 19b in der Beschick-Stellung 26b in eine nach hinten geneigte Freigabestellung geschwenkt.A similar arrangement and trajectory is also in the Training provided according to Figure 4, however, here has the Control curve 15b only the curve section 17b for the alignment path on, while the rest of the movement path through a Curve control is determined by a drive 18b is effected. This, e.g. trained as a cylinder drive Control drive 18b pivots the support arm 12b the base 2b in approximately the same way as the curve section 18b according to FIG. 3, namely simultaneously with the movement of the Carrier 3b by the lifting drive 19b and / or separately therefrom. During this movement, the rotor 16b lifts off the control curve 15b completely, so that the control curve 15b then is not effective. For this purpose, here is the curve section 17b not through a groove, but only through one only a convex circumferential curve or curve flank is formed, against which the rotor 16b by the control drive 18b over the Alignment path created and from which the runner 16b over the remaining movement path through the control drive 18b as well is lifted by the lifting drive 19b. The control drive too 18b can lie essentially in front of the supporting link and 4 in a side view according to FIG. 4 with the lifting drive 19b cross by going from the front end of the base 2b is inclined above and behind. In the loading position is the Control drive 18b thereby inclined flatter backwards than in the position associated with the alignment path, so that he the No insertion of the rollers along the support 20b Way handicapped. The linear actuator is also in a corresponding manner 19b in the loading position 26b to the rear inclined release position pivoted.

Durch die erfindungsgemäße Ausbildung kann die Ladevorrichtung vollständig automatisch arbeiten, wobei eine entsprechende Steuereinrichtung die beschriebenen Bewegungsabläufe koordiniert, nämlich die Rolle in den Bereich der Träger überführt, dann die Träger in Eingriff mit der Rolle bringt und diese schließlich in die Abrollstellung anhebt. Sensoren können dabei die Achshöhen sowie die Länge der Rolle bestimmen und die Rollenträger entsprechend steuern. Auch die Entnahme einer Rolle kann entsprechend automatisch gesteuert sein.Due to the inventive design, the loading device work fully automatically, taking a corresponding Control device the movements described coordinates, namely the role in the field of Carrier transferred, then the carrier into engagement with the roll brings and finally lifts them into the unwind position. Sensors can measure the shaft heights and the length of the roll determine and control the roller carrier accordingly. Also the Removal of a roll can be controlled automatically accordingly be.
