Definitions

  • the invention relates to a positioning device according to the preamble of claim 1.
  • piece goods can be moved in a predetermined movement path or in a fixed position, e.g. be provided in such a way that it is aligned with one, two or three perpendicular spatial axes with respect to a reference plane or a reference point or a base.
  • General cargo seen in at least one of the spatial axes, can have an irregular or regular rounded or angular shape, in particular an external shape, for example triangular, rectangular, square and similar.
  • the piece goods can be deformable, at least when they are in contact with a base surface, and are essentially incompressible, but essentially deformable parallel to the base surface, but can be deformed, as is the case, for example, with piece goods consisting of a large number of the same size and flush with one another in a stack lying sheet layers is the case which can be shifted against each other parallel to their planes or can be lifted off each other transversely to their planes
  • the piece goods form a strictly rectangular cuboid, which can be highly resistant to deformation, although its individual layers have thicknesses of less than two or one tenth of a millimeter and are essential in the case of paper or paper-like materials higher flexibility than e.g. metallic materials have approximately the same dimensions.
  • General cargo is aligned especially for the purpose of subsequent processing.
  • the piece goods are aligned with a packaging station, in which they are brought together in a precisely predetermined position with a flexible packaging wrapping that is still essentially spread out and this is then wrapped around the piece goods.
  • This can e.g. in that the piece goods are aligned between box-shaped walls and their four sides can slide transversely to a base surface and at right angles and parallel to each other on the inside walls.
  • EP-A-0 373 331 shows a transverse alignment according to the preamble of claim 1 with endless belts tapering towards one another, which are supported relentlessly on their rear sides with guide parts, so that they cannot yield under the force of their engagement in the piece goods.
  • DE-A-2 702 737 shows a guide section for general cargo with two parallel, lateral guide belts, a transverse orientation is not provided here, but only a lateral guide, holder or support.
  • Another object of the invention is to provide a positioning device in which disadvantages of known designs or of the type described are avoided and which ensures an increased working speed, in particular when the piece goods are subjected to low loads.
  • the features of claim 1 are provided.
  • the alignment can take place in that alignment surfaces act on closely delimited zones of the piece goods and thereby introduce alignment forces into the piece goods, each approximately parallel to one, two or three of the spatial axes can act in opposite directions after deviation from the desired alignment state.
  • Two or three alignment movements approximately at right angles to one another or parallel to the spatial axes are advantageously superimposed on one another in such a way that a reduction ratio between 5: 1 and 18: 1, in particular between 10: 1 and 14: 1, exists between at least two alignment movements with regard to the movement path , where, depending on the level of the alignment resistances between these limit values, any integer multiple can be advantageous.
  • the alignment along the relatively longer movement path can simultaneously serve to transport the piece goods, for example to an aligned ready position determined by the stop and / or interruption of the drive. Simultaneously with this conveying movement, the piece goods are then aligned in a direction transverse thereto by a relatively much smaller path and, if necessary, in a further direction transverse to the two aforementioned directions by a relatively even smaller path, namely transverse to its base surface.
  • This last alignment can be done in a simple manner in that the piece goods are pushed with their base surface onto a correspondingly aligned base surface.
  • the alignment base does not have to be moved relative to the device base, but the piece goods can be moved and thereby simultaneously transferred from one station, for example a stacking picture, to another work station, in which it then moves to the base area after two about parallel spatial axes arrives exactly aligned and is stopped.
  • the alignment movements are advantageously not in a vertical, but in a different, e.g. approximately horizontal direction, the base advantageously deviating from a vertical position, namely as a wing for receiving the weight on the underside of the piece goods.
  • two alignment movements are expediently approximately parallel to this direction or plane or, in the case of stack layers, parallel to their planes.
  • the alignment surfaces advantageously attack uniformly over the entire extent of the piece goods that lies transversely to the planes mentioned.
  • the alignment surfaces are brought into engagement with the associated counter surfaces of the piece goods over its entire associated extent essentially simultaneously by transverse movements.
  • the respective alignment surface can be tilted at least by a few angular degrees about an axis approximately parallel to it or approximately perpendicular to the base surface and at most at a short distance from it, so that it automatically adjusts itself to an essentially full-surface position under the contact forces can and not only lies in point or line form on the piece goods.
  • the alignment surface can be deflected at least over part of its travel in a direction away from the piece goods against a restoring force, so that it acts relatively softly on the piece goods. It is only at the end of their travel that the alignment surface is expediently or positively supported against such deflection movements, so that the general cargo is in any case forced into its predetermined alignment position in this last phase. In this last phase, the alignment surface can move outward on an arch path, by means of which the reduction ratio mentioned is reduced in this last phase.
  • a particularly fast way of working can be achieved if the alignment surfaces take over the respective piece goods from a conveyor running at a uniform speed, which expediently forms a substantially continuous continuation of the base area and on which the piece goods can then be roughly pre-aligned transversely to the conveying direction before it slides onto the actual base area.
  • the alignment surfaces can have a higher conveying speed than the conveyor, so that they catch up the piece goods in the manner of sliders on the back and after running onto the piece goods, they move them at a correspondingly higher speed relative to the transporter and the subsequent piece goods.
  • the alignment surfaces are then stopped, so that they continue to secure the piece goods and form a slide guide lying transversely to the base area, along which the piece goods can be transferred to the processing position of the associated work station.
  • the following piece goods are conveyed further at the same speed, the intermediate distances between successive piece goods being selected such that the alignment surfaces of the piece goods transferred into the working position are already released before they have to be moved again in order to take over a subsequent piece goods.
  • the positioning device 1 is used to feed piece goods 2, e.g. Paper giant of at least one or more 100 sheets each, to a work station, in which the piece goods 2 arrive precisely aligned in view of their underside or base surface 3, so that the work movement associated with the work station can be carried out by moving them at right angles to their base surface.
  • the piece goods 2 have, at right angles to the flat base surface 3 in pairs opposite one another and at right angles to one another, flat side surfaces 4 to 7 which adjoin one another in right-angled corner zones.
  • the base surface 3 is parallel to a flat top surface 8 of the same size.
  • the device 1 has, for example, a frame-like device base 9, which determines an alignment base 10, against which the respective piece goods 2 are to assume a more precisely determined, fixed position, both in plan view and in view of each side surface 4 to 7.
  • the height is determined by an essentially flat base or engagement surface 11 on which the piece goods 2 rests with the base surface 3.
  • a precise alignment transversely to the side surfaces 6, 7 is determined by a continuously flat alignment or engagement surface 12, which is used for the full-surface contact of the side surface 6 and in view of the Base 11 is at a distance from this, which can be on the order of a third of the distance between the side surfaces 6, 7.
  • the alignment surface 12 is opposite to approximately parallel and planar alignment or engagement surfaces 14, which are intended for the installation of the side surface 7 with areas that are only half to a twelfth, in particular a fifth to a tenth, of the total area correspond to the side surface 7.
  • Each alignment surface 14 directly adjoins in a rigid association with an approximately flat, also flat alignment or engagement surface 13, which is intended for contacting the associated side surface 4 or 5 with an area proportion which is also approximately of the order of magnitude mentioned can.
  • Alignment surfaces 13 are provided only at a distance from the alignment surface 12, namely in the region of the corner zone of the piece goods 2 delimited by the side surface 7, so that this does not directly adhere to the side surfaces 4, 5 over most of its extent between the side surfaces 6, 7 Alignment surfaces. All engagement surfaces 12 to 14 extend at least over the total height of the piece goods 2.
  • At least one, namely the alignment surface 12, is larger than the associated side surface 6, so that it protrudes beyond the base surface 3, the top surface 8 and / or the side surface 4 or 5 and the side surface 6 rests essentially over its entire surface.

Description

Die Erfindung betrifft eine Positioniervorrichtung nach dem Oberbegriff des Patentanspruches 1. Mit ihr kann Stückgut in einer vorbestimmten Bewegungsbahn bzw. einer lagefesten Position z.B. so bereitgestellt werden, daß es nach einer, zwei oder drei rechtwinklig zueinander stehenden Raumachsen gegenüber einer Referenzebene oder einem Referenzpunkt bzw. einer Basis ausgerichtet ist.The invention relates to a positioning device according to the preamble of claim 1. With it, piece goods can be moved in a predetermined movement path or in a fixed position, e.g. be provided in such a way that it is aligned with one, two or three perpendicular spatial axes with respect to a reference plane or a reference point or a base.

Stückgut kann, in mindestens einer der Raumachsen gesehen, unregelmäßige bzw. regelmäßige abgerundete bzw. eckige Form, insbesondere Außenform, haben, z.B. dreieckförmig, rechteckig, quadratisch und ähnlich sein. Ferner kann das Stückgut wenigstens bei Anlage an einer Grundfläche im wesentlichen biegesteif sowie quer zur Grundfläche im wesentlichen inkompressibel, jedoch etwa parallel zur Grundfläche nicht schubsteif, sondern verformbar sein, wie dies z.B. bei Stückgut aus einer Vielzahl von gleich großen und kantenbündig in einem Stapel aufeinander liegenden Blattlagen der Fall ist, welche gegeneinander parallel zu ihren Ebenen verschoben bzw. quer zu ihren Ebenen voneinander abgehoben werden können.General cargo, seen in at least one of the spatial axes, can have an irregular or regular rounded or angular shape, in particular an external shape, for example triangular, rectangular, square and similar. Furthermore, the piece goods can be deformable, at least when they are in contact with a base surface, and are essentially incompressible, but essentially deformable parallel to the base surface, but can be deformed, as is the case, for example, with piece goods consisting of a large number of the same size and flush with one another in a stack lying sheet layers is the case which can be shifted against each other parallel to their planes or can be lifted off each other transversely to their planes

Im durch die Gewichtskraft der Blattlagen zusammengepreßten Zustand bildet das Stückgut jedoch einen streng rechteckig begrenzten Quader, der in hohem Maße verformungssteif sein kann, obwohl seine Einzelschichten Dicken von weniger als zwei oder ein Zehntel Millimeter haben und im Falle von Papier bzw. papierähnlichen Werkstoffen eine wesentlich höhere Flexibilität als z.B. metallische Werkstoffe etwa gleicher Abmessungen aufweisen.In the state compressed by the weight of the sheet layers, however, the piece goods form a strictly rectangular cuboid, which can be highly resistant to deformation, although its individual layers have thicknesses of less than two or one tenth of a millimeter and are essential in the case of paper or paper-like materials higher flexibility than e.g. metallic materials have approximately the same dimensions.

Stückgut wird insbesondere zum Zwecke einer folgenden Be- bzw. Verarbeitung ausgerichtet. Z.B. wird das Stückgut gegenüber einer Verpackungsstation ausgerichtet, in welcher es in genau vorbestimmter Lage mit einer noch im wesentlichen ausgebreiteten flexiblen Verpackungs-Umhüllung zusammengeführt und diese dann um das Stückgut herumgeschlagen wird. Dies kann z.B. dadurch erfolgen, daß das Stückgut zwischen kastenförmig angeordneten Wänden ausgerichtet wird und dabei seine vier quer zu einer Basisfläche sowie im rechten Winkel und parallel zueinanderliegenden Außenseiten an den Wandinnenseiten gleiten können.General cargo is aligned especially for the purpose of subsequent processing. E.g. the piece goods are aligned with a packaging station, in which they are brought together in a precisely predetermined position with a flexible packaging wrapping that is still essentially spread out and this is then wrapped around the piece goods. This can e.g. in that the piece goods are aligned between box-shaped walls and their four sides can slide transversely to a base surface and at right angles and parallel to each other on the inside walls.

Die EP-A-0 373 331 zeigt eine Querausrichtung gemäß dem Oberbegriff des Anspruchs 1 mit trichterförmig aufeinander zulaufenden Endlosbändern, welche an ihren Rückseiten mit Führungsteilen unnachgiebig abgestützt sind, so daß sie unter der Eingriffskraft ihres Eingriffes in das Stückgut nicht nachgeben können.EP-A-0 373 331 shows a transverse alignment according to the preamble of claim 1 with endless belts tapering towards one another, which are supported relentlessly on their rear sides with guide parts, so that they cannot yield under the force of their engagement in the piece goods.

Die DE-A-2 702 737 zeigt eine Führungsstrecke für Stückgut mit zwei parallelen, seitlichen Führungsbändern, wobei eine Querausrichtung hier nicht vorgesehen ist, sondern lediglich eine seitliche Führung, Halterung bzw. Stützung.DE-A-2 702 737 shows a guide section for general cargo with two parallel, lateral guide belts, a transverse orientation is not provided here, but only a lateral guide, holder or support.

Der Erfindung liegt des weiteren als Aufgabe zugrunde, eine Positioniervorrichtung zu schaffen, bei welcher Nachteile bekannter Ausbildungen bzw. der beschriebenen Art vermieden sind und die insbesondere bei geringer Belastung des Stückgutes eine erhöhte Arbeitsgeschwindigkeit gewährleistet.Another object of the invention is to provide a positioning device in which disadvantages of known designs or of the type described are avoided and which ensures an increased working speed, in particular when the piece goods are subjected to low loads.

Erfindungsgemäß sind die Merkmale des Patentanspruches 1 vorgesehen. Die Ausrichtung kann dadurch erfolgen, daß Ausrichtflächen an eng begrenzten Zonen des Stückgutes angreifen und dadurch in das Stückgut Ausrichtkräfte einleiten, die etwa parallel zu einer, zwei oder drei der Raumachsen je nach Abweichung vom gewünschten Ausrichtzustand entgegengesetzt ausrichtend wirken können.According to the invention, the features of claim 1 are provided. The alignment can take place in that alignment surfaces act on closely delimited zones of the piece goods and thereby introduce alignment forces into the piece goods, each approximately parallel to one, two or three of the spatial axes can act in opposite directions after deviation from the desired alignment state.

Vorteilhaft werden dabei zwei oder drei etwa rechtwinklig zueinander bzw. parallel zu den Raumachsen liegende Ausrichtbewegungen einander so überlagert, daß sich zwischen mindestens zwei Ausrichtbewegungen hinsichtlich des Bewegungsweges ein Untersetzungsverhältnis zwischen 5 : 1 und 18 : 1, insbesondere zwischen 10 : 1 und 14 : 1, ergibt, wobei je nach Höhe der Ausrichtwiderstände zwischen diesen Grenzwerten jedes ganzzahlige Vielfache vorteilhaft sein kann.Two or three alignment movements approximately at right angles to one another or parallel to the spatial axes are advantageously superimposed on one another in such a way that a reduction ratio between 5: 1 and 18: 1, in particular between 10: 1 and 14: 1, exists between at least two alignment movements with regard to the movement path , where, depending on the level of the alignment resistances between these limit values, any integer multiple can be advantageous.

Die Ausrichtung entlang des relativ längeren Bewegungsweges kann gleichzeitig zum Transport des Stückgutes dienen, beispielsweise zu einer durch Anschlag und/oder Unterbrechung des Antriebes bestimmten ausgerichteten Bereitstellungslage. Simultan mit dieser Förderbewegung wird dann das Stückgut in einer Richtung quer dazu um einen relativ wesentlich kleineren weg ausgerichtet und ggf. in einer weiteren Richtung quer zu beiden zuvor genannten Richtungen um einen relativ nochmals kleineren weg ausgerichtet, nämlich quer zu seiner Basisfläche.The alignment along the relatively longer movement path can simultaneously serve to transport the piece goods, for example to an aligned ready position determined by the stop and / or interruption of the drive. Simultaneously with this conveying movement, the piece goods are then aligned in a direction transverse thereto by a relatively much smaller path and, if necessary, in a further direction transverse to the two aforementioned directions by a relatively even smaller path, namely transverse to its base surface.

Diese letzte Ausrichtung kann in einfacher Weise dadurch erfolgen, daß das Stückgut mit seiner Basisfläche auf eine entsprechend ausgerichtete Grundfläche geschoben wird. Durch diese Ausbildung braucht die Ausricht-Basis nicht gegenüber dem Vorrichtungs-Sockel bewegt zu werden, sondern es kann das Stückgut bewegt und dadurch gleichzeitig von einer Station, z.B. einem Stapelbilder, zu einer weiteren Arbeitsstation überführt werden, in welcher es dann nach zwei zur Grundfläche etwa parallelen Raumachsen genau ausgerichtet ankommt und stillgesetzt wird.This last alignment can be done in a simple manner in that the piece goods are pushed with their base surface onto a correspondingly aligned base surface. With this design, the alignment base does not have to be moved relative to the device base, but the piece goods can be moved and thereby simultaneously transferred from one station, for example a stacking picture, to another work station, in which it then moves to the base area after two about parallel spatial axes arrives exactly aligned and is stopped.

Die Ausrichtbewegungen erfolgen vorteilhaft nicht in einer vertikalen, sondern in einer davon abweichenden, z.B. annähernd horizontalen Richtung, wobei die Grundfläche vorteilhaft von einer vertikalen Lage abweicht, nämlich als Tragfläche zur Aufnahme des Gewichtes an der Unterseite des Stückgutes liegt. Im Falle eines in einer Richtung bzw. Ebene auf Schub nachgiebigen Stückgutes liegen zweckmäßig zwei Ausrichtbewegungen etwa parallel zu dieser Richtung oder Ebene bzw. im Falle von Stapellagen parallel zu deren Ebenen. In diesem Fall greifen die Ausrichtflächen vorteilhaft gleichmäßig über diejenige gesamte Erstreckung des Stückgutes an, die quer zu den genannten Ebenen liegt. Die Ausrichtflächen werden mit den zugehörigen Gegenflächen des Stückgutes über dessen gesamte zugehörige Erstreckung im wesentlichen gleichzeitig durch Querbewegungen in Eingriff gebracht.The alignment movements are advantageously not in a vertical, but in a different, e.g. approximately horizontal direction, the base advantageously deviating from a vertical position, namely as a wing for receiving the weight on the underside of the piece goods. In the case of a piece of material which yields to thrust in one direction or plane, two alignment movements are expediently approximately parallel to this direction or plane or, in the case of stack layers, parallel to their planes. In this case, the alignment surfaces advantageously attack uniformly over the entire extent of the piece goods that lies transversely to the planes mentioned. The alignment surfaces are brought into engagement with the associated counter surfaces of the piece goods over its entire associated extent essentially simultaneously by transverse movements.

Die jeweilige Ausrichtfläche kann um eine zu ihr etwa parallele bzw. zur Grundfläche etwa rechtwinklige und höchstens mit geringem Abstand von ihr liegende Achse selbsteinstellend zumindest um wenige Winkelgrade kippbar sein, so daß sie sich unter den Anlagekräften von selbst in eine im wesentlichen ganzflächig anliegende Lage einstellen kann und nicht nur punkt- bzw. linienförmig am Stückgut anliegt. Ferner kann die Ausrichtfläche wenigstens auf einem Teil ihres Stellweges in einer Richtung weg vom Stückgut gegen eine Rückstellkraft auslenkbar sein, so daß sie auf das Stückgut verhältnismäßig weich ausrichtend wirkt. Erst am Ende ihres Stellweges wird die Ausrichtfläche dann zweckmäßig gegen solche Auslenkbewegungen formschlüssig bzw. starr abgestützt, so daß das Stückgut in dieser letzten Phase auf jeden Fall in seine vorbestimmte Ausrichtlage gezwungen wird. In dieser letzten Phase kann sich die Ausrichtfläche dabei nach außen gerichtet auf einer Bogenbahn bewegen, durch die das genannte Untersetzungsverhältnis in dieser letzten Phase reduziert wird.The respective alignment surface can be tilted at least by a few angular degrees about an axis approximately parallel to it or approximately perpendicular to the base surface and at most at a short distance from it, so that it automatically adjusts itself to an essentially full-surface position under the contact forces can and not only lies in point or line form on the piece goods. Furthermore, the alignment surface can be deflected at least over part of its travel in a direction away from the piece goods against a restoring force, so that it acts relatively softly on the piece goods. It is only at the end of their travel that the alignment surface is expediently or positively supported against such deflection movements, so that the general cargo is in any case forced into its predetermined alignment position in this last phase. In this last phase, the alignment surface can move outward on an arch path, by means of which the reduction ratio mentioned is reduced in this last phase.

Eine besonders schnelle Arbeitsweise ist zu erreichen, wenn die Ausrichtflächen das jeweilige Stückgut von einem mit gleichmäßiger Geschwindigkeit laufenden Förderer übernehmen, der zweckmäßig eine im wesentlichen kontinuierliche Fortsetzung der Grundfläche bildet und auf dem das Stückgut dann quer zur Förderrichtung bereits grob vorausgerichtet werden kann, bevor es auf die eigentliche Grundfläche gleitet. Die Ausrichtflächen können dabei eine größere Fördergeschwindigkeit als der Förderer haben, so daß sie das Stückgut nach Art von Schiebern an der Rückseite einholen und nach dem Auflaufen auf das Stückgut dieses mit entsprechend höherer Geschwindigkeit gleitend gegenüber dem Transporteur und dem nachfolgenden Stückgut bewegen. Bei Erreichen der ausgerichteten Bereitstellungslage werden die Ausrichtflächen dann stillgesetzt, so daß sie das Stückgut weiterhin sichern und eine quer zur Grundfläche liegende Gleitführung bilden, entlang welcher das Stückgut in die Verarbeitungslage der zugehörigen Arbeitsstation überführt werden kann. Während dieses Verfahrensschrittes werden die nachfolgenden Stückgüter mit gleicher Geschwindigkeit weitergefördert, wobei die Zwischenabstände zwischen aufeinanderfolgenden Stückgütern so gewählt sind, daß die Ausrichtflächen von dem in Arbeitsposition überführten Stückgut bereits freigegeben sind, bevor sie zur Übernahme eines nachfolgenden Stückgutes wieder bewegt werden müssen.A particularly fast way of working can be achieved if the alignment surfaces take over the respective piece goods from a conveyor running at a uniform speed, which expediently forms a substantially continuous continuation of the base area and on which the piece goods can then be roughly pre-aligned transversely to the conveying direction before it slides onto the actual base area. The alignment surfaces can have a higher conveying speed than the conveyor, so that they catch up the piece goods in the manner of sliders on the back and after running onto the piece goods, they move them at a correspondingly higher speed relative to the transporter and the subsequent piece goods. When the aligned ready position is reached, the alignment surfaces are then stopped, so that they continue to secure the piece goods and form a slide guide lying transversely to the base area, along which the piece goods can be transferred to the processing position of the associated work station. During this process step, the following piece goods are conveyed further at the same speed, the intermediate distances between successive piece goods being selected such that the alignment surfaces of the piece goods transferred into the working position are already released before they have to be moved again in order to take over a subsequent piece goods.

Diese und weitere Merkmale gehen außer aus den Ansprüchen auch aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei einer Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird. Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher erläutert. In den Zeichnungen zeigen:

These and further features emerge from the claims and also from the description and the drawings, the individual features being realized individually or in groups in the form of sub-combinations in one embodiment of the invention and in other fields and being advantageous and capable of being protected by themselves Can represent versions for which protection is claimed here. On Embodiment of the invention is illustrated in the drawings and is explained in more detail below. The drawings show:
Fig. 1
a positioning device according to the invention in plan view and simplified representation and
Fig. 2
a movement of the positioning device in a schematic representation.

Die Positioniervorrichtung 1 dient zur Zuförderung von Stückgut 2, z.B. Papier-Riese von jeweils mindestens oder mehreren 100 Blatt, zu einer Arbeitsstation, in welcher das Stückgut 2 in Ansicht auf seine Unterseite bzw. Basisfläche 3 genau ausgerichtet ankommt, so daß es durch Bewegen rechtwinklig zu seiner Basisfläche die der Arbeitsstation zugehörige Arbeitsbewegung ausführen kann. Das Stückgut 2 weist rechtwinklig zur ebenen Basisfläche 3 paarweise einander gegenüber- und im rechten Winkel zueinander liegende ebene Seitenflächen 4 bis 7 auf, die in rechtwinklig scharfen Eckzonen aneinander schließen. Der Basisfläche 3 liegt eine gleichgroße ebene Deckfläche 8 parallel gegenüber.The positioning device 1 is used to feed piece goods 2, e.g. Paper giant of at least one or more 100 sheets each, to a work station, in which the piece goods 2 arrive precisely aligned in view of their underside or base surface 3, so that the work movement associated with the work station can be carried out by moving them at right angles to their base surface. The piece goods 2 have, at right angles to the flat base surface 3 in pairs opposite one another and at right angles to one another, flat side surfaces 4 to 7 which adjoin one another in right-angled corner zones. The base surface 3 is parallel to a flat top surface 8 of the same size.

Die Vorrichtung 1 weist einen z.B. gestellartigen Vorrichtungs-Sockel 9 auf, welcher eine Ausricht-Basis 10 bestimmt, gegenüber welcher das jeweilige Stückgut 2 sowohl in Draufsicht als auch in Ansicht auf jede Seitenfläche 4 bis 7 eine genauer bestimmte, feststehende Lage einnehmen soll. Die Höhenlage ist durch eine im wesentlichen ebene Grund- bzw. Eingriffsfläche 11 bestimmt, auf welcher das Stückgut 2 mit der Basisfläche 3 aufliegt. Eine genaue Ausrichtung quer zu den Seitenflächen 6, 7 ist durch eine durchgehend ebene Ausricht- bzw. Eingriffsfläche 12 bestimmt, die zur ganzflächigen Anlage der Seitenfläche 6 dient und in Ansicht auf die Grundfläche 11 in einem Abstand von dieser liegt, der in der Größenordnung eines Drittels des Abstandes zwischen den Seitenflächen 6, 7 liegen kann.The device 1 has, for example, a frame-like device base 9, which determines an alignment base 10, against which the respective piece goods 2 are to assume a more precisely determined, fixed position, both in plan view and in view of each side surface 4 to 7. The height is determined by an essentially flat base or engagement surface 11 on which the piece goods 2 rests with the base surface 3. A precise alignment transversely to the side surfaces 6, 7 is determined by a continuously flat alignment or engagement surface 12, which is used for the full-surface contact of the side surface 6 and in view of the Base 11 is at a distance from this, which can be on the order of a third of the distance between the side surfaces 6, 7.

In Bereitstellungslage gemäß Fig. 1 liegen der Ausrichtfläche 12 etwa parallele sowie ebene Ausricht- bzw. Eingriffsflächen 14 gegenüber, die für die Anlage der Seitenfläche 7 mit Flächenanteilen bestimmt sind, die nur der Hälfte bis einem Zwölftel, insbesondere einem Fünftel bis einem Zehntel der Gesamtfläche der Seitenfläche 7 entsprechen. An jede Ausrichtfläche 14 schließt in starrer Zuordnung unmittelbar eine etwa rechtwinklig dazu liegende, ebenfalls ebene Ausricht- bzw. Eingriffsfläche 13 an, die zur Anlage der jeweils zugehörigen Seitenfläche 4 bzw. 5 mit einem Flächenanteil bestimmt ist, der ebenfalls etwa in der genannten Größenordnung liegen kann. Ausrichtflächen 13 sind nur im Abstand von der Ausrichtfläche 12, nämlich im Bereich der von der Seitenfläche 7 begrenzten Eckzone des Stückgutes 2 vorgesehen, so daß dieses auf dem größten Teil seiner Erstreckung zwischen den Seitenflächen 6, 7 an den Seitenflächen 4, 5 nicht unmittelbar an Ausrichtflächen anliegt. Alle Eingriffsflächen 12 bis 14 reichen mindestens über die Gesamthöhe des Stückgutes 2.In the ready position according to FIG. 1, the alignment surface 12 is opposite to approximately parallel and planar alignment or engagement surfaces 14, which are intended for the installation of the side surface 7 with areas that are only half to a twelfth, in particular a fifth to a tenth, of the total area correspond to the side surface 7. Each alignment surface 14 directly adjoins in a rigid association with an approximately flat, also flat alignment or engagement surface 13, which is intended for contacting the associated side surface 4 or 5 with an area proportion which is also approximately of the order of magnitude mentioned can. Alignment surfaces 13 are provided only at a distance from the alignment surface 12, namely in the region of the corner zone of the piece goods 2 delimited by the side surface 7, so that this does not directly adhere to the side surfaces 4, 5 over most of its extent between the side surfaces 6, 7 Alignment surfaces. All engagement surfaces 12 to 14 extend at least over the total height of the piece goods 2.

Mindestens eine, nämlich die Ausrichtfläche 12, ist größer als die zugehörige Seitenfläche 6, so daß sie über die Basisfläche 3, die Deckfläche 8 und/oder die Seitenfläche 4 bzw. 5 vorsteht und die Seitenfläche 6 im wesentlichen ganzflächig an ihr anliegt. Die Ausrichtfläche 12 ist durch eine Plattenfläche eines plattenförmigen Ausrichtkörpers bzw. Eingriffsgliedes 15 gebildet, das zweckmäßig im wesentlichen vertikal steht. Jeweils ein Paar aus zwei eine einspringende Eckzone begrenzenden Ausrichtflächen 13, 14 ist durch einen im Querschnitt winkelförmigen Ausrichtkörper bzw. ein Eingriffsglied 16 bzw. 17 gebildet, das als winkelförmig über seine Gesamtlänge konstant durchgehender Profilstab ausgebildet ist und sich etwa rechtwinklig zur Grundfläche 11 bzw. etwa parallel zur Ausrichtfläche 12 erstreckt. Der die breitere Ausrichtfläche 13 bildende Winkelschenkel ist länger als der die schmalere Ausrichtfläche 14 bildende Winkelschenkel. Jede Ausrichtfläche 14 liegt in Draufsicht mit einem Seitenabstand von der Grundfläche 11, während jede Ausrichtfläche 13 in der Bereitstellungslage mit einem demgegenüber wesentlichen größeren Abstand von der Ausrichtfläche 12 liegt. Der Winkel zwischen den Ausrichtflächen 13, 14 entspricht im wesentlichen genau dem Winkel zwischen den zugehörigen Seitenflächen 4, 7 bzw. 5, 7 im Bereich der Eckzone des Stückgutes 2.At least one, namely the alignment surface 12, is larger than the associated side surface 6, so that it protrudes beyond the base surface 3, the top surface 8 and / or the side surface 4 or 5 and the side surface 6 rests essentially over its entire surface. The alignment surface 12 is formed by a plate surface of a plate-shaped alignment body or engaging member 15, which advantageously is essentially vertical. A pair of two alignment surfaces 13, 14 delimiting a protruding corner zone is formed by an alignment body or an engagement member 16 or 17 which is angular in cross section and which is angular over its entire length constant continuous profile rod is formed and extends approximately at right angles to the base surface 11 or approximately parallel to the alignment surface 12. The angle leg forming the wider alignment surface 13 is longer than the angle leg forming the narrower alignment surface 14. Each alignment surface 14 lies in a top view with a lateral distance from the base surface 11, while each alignment surface 13 lies in the ready position with a considerably greater distance from the alignment surface 12. The angle between the alignment surfaces 13, 14 essentially corresponds exactly to the angle between the associated side surfaces 4, 7 and 5, 7 in the region of the corner zone of the piece goods 2.

Die Ausrichtfläche 12 ist nach Art eines Endanschlages nicht durch direkten Antrieb bewegt bzw. im wesentlichen feststehend angeordnet, während die Ausrichtflächen 1, 14 jeweils mit dem Stückgut 2 quer gegen die Ausrichtfläche 12 durch Antrieb bewegbar sind. Zu diesem Zweck ist der jeweilige Ausrichtkörper 16 bzw. 17 an zwei im wesentlichen gleichen Tragorganen 18 befestigt, die quer zur Grundfläche 11 bzw. parallel zur Ausrichtfläche 12 im Abstand voneinander liegen und in deren Längsrichtung der jeweilige Ausrichtkörper 16 bzw. 17 im wesentlichen starr bzw. formschlüssig befestigt ist.In the manner of an end stop, the alignment surface 12 is not moved by a direct drive or is arranged essentially stationary, while the alignment surfaces 1, 14 can each be moved transversely against the alignment surface 12 by the drive with the piece goods 2. For this purpose, the respective alignment body 16 or 17 is fastened to two essentially identical support members 18 which are spaced apart from one another transversely to the base surface 11 or parallel to the alignment surface 12 and in the longitudinal direction of which the respective alignment body 16 or 17 is essentially rigid or is positively attached.

Die Tragorgane 18 sind zweckmäßig durch Rollenketten, Zahnriemen oder dgl. gebildet, so daß sie schlupffrei angetrieben werden können. Das jeweils dem Stückgut 2 zugekehrte Trum jedes Tragorganes 18 liegt als Eingriffsträger 19 in Ansicht auf die Grundfläche 11 gemäß Fig. 1 unter einem spitzen Winkel von weniger als 30, 20, 15 oder 10° gegenüber einer zu den Flächen 11, 12 etwa rechtwinkligen Ebene bzw. zur zugehörigen Seitenfläche 4 bzw. 5 und nähert sich zur Ausrichtfläche 12 deren Mitte an. Durch diese Lage des Trums 19 ist die jeweils ausrichtend wirksame Bewegungsbahn der zugehörigen Ausrichtfläche 13, 14 bestimmt. Die Tragorgane 18 sind jeweils endlos um zwei quer zur Ausrichtfläche 12 hintereinander liegende Rück-Umlenkungen 20, 21 in Form von Kettenrädern geführt, von denen die näher bei der Ausrichtfläche 12 liegende Umlenkung einen um etwa ein Drittel kleineren Umlenkradius hat. Gegenüber der zu den Flächen 11, 12 rechtwinkligen Mittelebene der Ausrichtbasis 10 haben die Achsen 22 der vorderen, näher bei der Ausrichtfläche 12 liegenden Umlenkungen 20 einen kleineren Abstand als die Achse 23 der jeweils hinteren Umlenkung 21, wobei jedoch die gemeinsame Axialebene der Umlenkungen 22, 23 zum Trum 19 unter einem sich zur Ausrichtfläche 12 schließenden Winkel von wenigen Winkelgraden liegt. An jedem Tragorgan 18 können über dessen Länge zwei oder mehr Ausrichtkörper 16, 17 in gleichmäßigen Abständen verteilt sein, die aufeinanderfolgend zur Ausrichtung aufeinanderfolgender Stückgüter 2 wirksam werden, so daß eine schnelle Arbeitsfolge bei relativ geringen Umlaufgeschwindigkeiten und stets gleicher Umlaufrichtung möglich ist.The support members 18 are expediently formed by roller chains, toothed belts or the like. So that they can be driven without slippage. The strand of each support element 18 facing the piece goods 2 is located as an engagement support 19 in view of the base surface 11 according to FIG. 1 at an acute angle of less than 30, 20, 15 or 10 ° with respect to a plane approximately perpendicular to the surfaces 11, 12 or to the associated side surface 4 or 5 and approaches the center of the alignment surface 12. Due to this position of the strand 19, the respectively effective movement path of the associated one Alignment surface 13, 14 determined. The support members 18 are in each case endlessly guided around two rear deflections 20, 21 lying one behind the other transversely to the alignment surface 12 in the form of sprockets, of which the deflection closer to the alignment surface 12 has a deflection radius which is approximately one third smaller. Compared to the center plane of the alignment base 10, which is perpendicular to the surfaces 11, 12, the axes 22 of the front deflections 20, which are closer to the alignment surface 12, are at a smaller distance than the axis 23 of the respective rear deflection 21, although the common axial plane of the deflections 22, 23 to the strand 19 lies at an angle of a few degrees of angle closing to the alignment surface 12. On each support member 18, two or more alignment bodies 16, 17 can be distributed at equal intervals along its length, which act successively for aligning successive piece goods 2, so that a rapid work sequence is possible at relatively low speeds and always the same direction of rotation.

Die Tragorgane 18 bzw. die Umlenkungen 20, 21 sind auf einer Konsole 24 gelagert, die am Sockel 9 quer zur Ausrichtfläche 12 bzw. etwa parallel zur Grundfläche 11 stufenlos verstellbar und in der jeweils eingestellten Lage festsetzbar sein kann. Ferner sind die Tragorgane 18 bzw. Trume 19 einschließlich der Umlenkungen 20, 21 quer zur genannten Mittelebene bzw. etwa parallel zu den Eingriffsflächen 11, 12 in entsprechender Weise verstellbar und festsetzbar. Dadurch kann die Vorrichtung 1 auf Stückgut 2 unterschiedlicher Größe eingestellt werden. Die Querverstellbarkeit kann gegenläufig z.B. durch Gestänge oder dgl. so zwangssynchronisiert sein, daß beide Trume oder Eingriffstgräger 19 stets den gleichen Abstand von der genannten Mittelebene haben.The support members 18 and the deflections 20, 21 are mounted on a bracket 24, which can be continuously adjusted on the base 9 transversely to the alignment surface 12 or approximately parallel to the base surface 11 and can be fixed in the respectively set position. Furthermore, the support members 18 or dreams 19 including the deflections 20, 21 can be adjusted and fixed transversely to the aforementioned central plane or approximately parallel to the engagement surfaces 11, 12 in a corresponding manner. As a result, the device 1 can be set for piece goods 2 of different sizes. The transverse adjustability can be oppositely synchronized, for example, by linkage or the like, in such a way that both strands or engagement supports 19 are always at the same distance from the median plane mentioned.

Die Wellen der Umlenkungen 20, 21 sind jeweils in Lagerungen 25, 26 gelagert, welche in der beschriebenen Weise verstellbar sind. Der jeweiligen hinteren Lagerung 26 ist eine Spannvorrichtung 27 zugeordnet, durch welche das zugehörige Tragorgan 18 stufenlos auf Zug gespannt und im jeweils eingestellten Spannzustand gesichert werden kann. Zwischen den beiden End-Umlenkungen 20, 21 ist das jeweilige Trum 19 an der Innenseite nicht abgestützt, sondern gegen seine Zugspannung in eine flache Bogenlage nach innen drückbar, wobei eine solche Bogenlage links in Fig. 1 strichpunktiert angedeutet ist. Die gegen die Auslenkung wirkende federnde Kraft ist dabei unmittelbar benachbart zur jeweiligen Umlenkung 20, 21 am größten und nimmt zur Mitte der Länge des Trums 19 stetig ab, wo sie am kleinsten ist. Diese Länge ist größer als die entsprechende Länge des Stückgutes 2 und kleiner als das Doppelte davon.The shafts of the deflections 20, 21 are each mounted in bearings 25, 26, which are adjustable in the manner described. The respective rear bearing 26 is assigned a tensioning device 27, by means of which the associated support member 18 can be continuously tensioned in tension and secured in the respectively set tensioning state. Between the two end deflections 20, 21, the respective strand 19 is not supported on the inside, but rather can be pressed inward against its tension into a flat sheet position, such a sheet position being indicated by dash-dotted lines on the left in FIG. 1. The resilient force acting against the deflection is greatest directly adjacent to the respective deflection 20, 21 and decreases steadily towards the middle of the length of the run 19, where it is the smallest. This length is greater than the corresponding length of the piece good 2 and less than double it.

Der Ausrichtkörper 15 ist quer bzw. etwa rechtwinklig zur Ausrichtfläche 12 in einer Lagerung 28 des Sockels 9 z.B. dadurch gelagert, daß an der Rückseite des Ausrichtkörpers 15 mehrere im Abstand zueinander liegende Gleitstangen vorgesehen sind, die in Gleitbuchsen laufen. Der Ausrichtkörper 15 ist jedoch nur gegen einen verhältnismäßig großen Widerstand durch Druck gegen die Außenfläche 12 bewegbar, weil diesem Druck eine Gegenkraft 29 entgegenwirkt, z.B. eine den Ausrichtkörper 15 bei Freigabe selbstrückstellende Federanordnung. Diese Anordnung kann z.B. durch eine oder mehrere pneumatische Kolbenfedern gebildet und ihre Widerstandskraft bzw. Federcharakteristik zur Anpassung an das Gewicht, die Reibungswiderstände oder dgl. des Stückgutes 2 stufenlos veränderbar sein.The alignment body 15 is transversely or approximately at right angles to the alignment surface 12 in a bearing 28 of the base 9, e.g. characterized in that a plurality of spaced-apart slide rods are provided on the back of the alignment body 15, which run in slide bushes. However, the alignment body 15 can only be moved against a relatively large resistance by pressure against the outer surface 12, because this pressure is counteracted by a counterforce 29, e.g. a spring arrangement which self-resets the alignment body 15 when released. This arrangement can e.g. formed by one or more pneumatic piston springs and their resistance or spring characteristics to adapt to the weight, the frictional resistances or the like.

An die von der Ausrichtfläche 12 entfernte Seite der Grundfläche 11 schließt ein etwa in der genannten Mittelebene liegender Transporteur 30 für das Stückgut 2 an, der z.B. durch das obere Trum eines Band-Transporteurs gebildet sein kann und dessen den Basisflächen 3 zugehörige Tragfläche wenigstens im Bereich benachbart zur Grundfläche 11 mit dieser etwa in einer Ebene bzw. demgegenüber geringfügig höher liegt. Die Grundfläche 11 ist durch einen quer bzw. rechtwinklig zu ihr bewegbaren Hubtisch gebildet, der als Eingriffsglied 32 aus der gegenüber dem Transporteur 30 etwa ebenengleichen Bereitstellungslage um einen Betrag angehoben werden kann, der größer als der Abstand zwischen der Basisfläche 3 und der Deckfläche 8 des Stückgutes 2 ist. Die Gleit- bzw. Eingriffsflächen 12 bis 14 stehen etwa gleich weit und weiter als das Stückgut 2 über die Grundfläche 11 vor, jedoch kann der Hubtisch 32 bzw. die Grundfläche 11 über die zugehörigen Enden der Gleitflächen hinausbewegt werden.The side of the base surface 11 remote from the alignment surface 12 is approximately in the said central plane lying conveyor 30 for the piece goods 2, which can be formed, for example, by the upper run of a belt conveyor, and whose supporting surface, which is associated with the base surfaces 3, lies at least in the region adjacent to the base surface 11 with the latter approximately in one plane or, in contrast, slightly higher. The base surface 11 is formed by a lifting table which can be moved transversely or at right angles to it, which can be raised as an engagement member 32 from the supply position which is approximately level with the transporter 30 by an amount which is greater than the distance between the base surface 3 and the top surface 8 of the General cargo 2 is. The sliding or engaging surfaces 12 to 14 protrude approximately the same distance and further than the piece goods 2 from the base 11, however the lifting table 32 or the base 11 can be moved beyond the associated ends of the sliding surfaces.

Das vordere Ende des Transportbandes läuft so über eine Umlenkung 31, daß es in Ansicht gemäß Fig. 1 nur einen kleinen Spaltabstand von der zugehörigen Kante der Grundfläche 11 hat und dadurch eine Übergabestation 33 gebildet ist, an welcher das Stückgut 2 vom bewegten Transporteur 30 so auf die feststehende Grundfläche 11 bewegt werden kann, daß es vom Transporteur 30 vollständig freikommt. In Bereitstellungslage ist die Grundfläche 11 bzw. der Hubtisch 32 gegenüber einer bis allen Seitenflächen 4 bis 7 des Stückgutes 2 mit Abstand nach innen versetzt, wobei der Abstand von den Seitenflächen 4, 5 kleiner als der Abstand von der Seitenfläche 6 sein und die zugehörige Außenkante mit der Seitenfläche 7 etwa so fluchten kann, daß sie über diese nicht vorsteht. Die Breite der Tragfläche des Transporteurs 30 ist ebenfalls schmaler als die des Stückgutes 2 und auch als die der Grundfläche 11, so daß das Stückgut 2 beiderseits seitlich über den Transporteur 30 annähernd gleich weit frei bzw. ununterstützt vorsteht, was in Fig. 1 übertrieben dargestellt ist. Die Grundfläche 11 bzw. der Tisch 32 ist zweckmäßig aus ebenengleichen bzw. aneinanderschließenden Formatteilen zusammengesetzt. Durch Herausnehmen oder Hinzufügen solcher Formatteile kann die Grundfläche 11 an unterschiedliche Grundrisse von Stückgut 2 angepaßt werden.The front end of the conveyor belt runs over a deflection 31 that it has only a small gap distance from the associated edge of the base 11 in the view according to FIG. 1 and thereby a transfer station 33 is formed, at which the piece goods 2 from the moving conveyor 30 so can be moved to the fixed base 11 that it is completely released from the transporter 30. In the ready position, the base surface 11 or the lifting table 32 is offset inward from one to all side surfaces 4 to 7 of the piece goods 2, the distance from the side surfaces 4, 5 being smaller than the distance from the side surface 6 and the associated outer edge can align with the side surface 7 so that it does not protrude beyond it. The width of the support surface of the transporter 30 is also narrower than that of the piece goods 2 and also that of the base area 11, so that the piece goods 2 protrudes on both sides laterally over the feed dog 30 approximately equally freely or unsupported, which is exaggerated in FIG. 1 is. The footprint 11 or the table 32 is expediently composed of flat parts of the same or adjacent format. By removing or adding such format parts, the base 11 can be adapted to different layouts of piece goods 2.

Der Transporteur 30 fördert das Stückgut 2 in Förder- bzw. Laufrichtung 34 rechtwinklig zur Ausrichtfläche 12 mit konstanter Geschwindigkeit und gleichen Zwischenabständen, die etwa dem Ein- bis Zweifachen der zugehörigen Erstreckung des Stückgutes 2 bzw. der Länge der Trume 19 entsprechen, wobei die etwa rechtwinklig zur Laufrichtung 34 liegende Seitenfläche 6 die vordere und die davon abgekehrte parallele Seitenfläche 7 die hintere Seitenfläche bildet, während die Seitenflächen 4, 5 etwa parallel zur Laufrichtung 34 liegen. Sobald das Fördergut 2 in den Bereich zwischen den beiden einander gegenüberstehenden Umlenkungen 21 gelangt ist, werden die bis dahin stillstehenden Tragorgane 18 durch Antrieb in dem Sinne in Bewegung versetzt, daß sie im Bereich der Trume 19 etwa in gleicher Richtung wie der Transporteur 30 laufen. Die zur Ausrichtung bestimmten Ausrichtkörper 16, 17 werden dabei über den größten Teil der Umlenkungen 21 so bewegt, daß die Ausrichtflächen 14 zunächst im Abstand hinter der hinteren Seitenfläche 7 liegen. Während des Laufes um die Umlenkungen 21 nähern sich dabei die Ausrichtflächen 13, 14 zunächst mit einer Geschwindigkeit seitlich bzw. quer zur Förderrichtung 34 dem Stückgut 2 an, die größer als die Geschwindigkeitskomponente parallel zur Laufrichtung 34 ist, wobei diese Geschwindigkeitskomponente zunächst kleiner als die Fördergeschwindigkeit des Transporteurs 30 ist.The conveyor 30 conveys the piece goods 2 in the conveying or running direction 34 at right angles to the alignment surface 12 at a constant speed and at equal intervals, which correspond approximately to one to two times the associated extent of the piece goods 2 or the length of the strands 19, the approximately Side surface 6 lying at right angles to the running direction 34 forms the front side and the parallel side surface 7 remote therefrom forms the rear side surface, while the side surfaces 4, 5 lie approximately parallel to the running direction 34. As soon as the material to be conveyed 2 has reached the area between the two opposing deflections 21, the support members 18, which had been stationary until then, are set in motion by drive in the sense that they run in the area of the dreams 19 in approximately the same direction as the transporter 30. The alignment bodies 16, 17 intended for alignment are moved over most of the deflections 21 in such a way that the alignment surfaces 14 are initially at a distance behind the rear side surface 7. During the run around the deflections 21, the alignment surfaces 13, 14 initially approach the piece goods 2 at a speed laterally or transversely to the conveying direction 34, which is greater than the speed component parallel to the running direction 34, this speed component initially being less than the conveying speed of the transporter 30.

Im weiterne Verlauf nimmt die Annäherungsgeschwindigkeit ab und die Förderkomponente der Ausrichtflächen 13, 14 zu, bis sie beim Verlassen der Umlenkung 21 denjenigen Wert erreicht haben, der der Bewegungsrichtung und Bewegungsgeschwindigkeit des Trums 19 entspricht und über dessen Länge im wesentlichen konstant ist. Beim Verlassen der Umlenkung 21 liegen die Ausrichtflächen 13, 14 noch im Abstand hinter der Seitenfläche 7, jedoch ist ihre Geschwindigkeit in Förderrichtung 34 größer als die des Transporteurs 30.In the further course, the approach speed decreases and the conveying component of the alignment surfaces 13, 14 increases until when they have left the deflection 21 they have reached that value which corresponds to the direction and speed of movement of the strand 19 and is essentially constant over its length. When leaving the deflection 21, the alignment surfaces 13, 14 are still at a distance behind the side surface 7, but their speed in the conveying direction 34 is greater than that of the conveyor 30.

In Fig. 2 sind die Bewegungen bzw. Bewegungskomponenten als Geschwindigkeitsvektoren angegeben, nämlich die schräge Stellbewegung der Ausrichtflächen 13, 14 im Bereich des Trums 19 mit dem Pfeil 35, die Förderbewegung des Transporteurs 30 mit dem Vektor 36, die parallel zur Förderrichtung 34 liegende Bewegungskomponente der Ausrichtflächen 13, 14 mit dem Vektor 37 und die quer zur Förderrichtung 34 liegende Bewegungskomponente mit dem Vektor 38. Aufgrund der gegenüber der Bewegung 36 schnelleren Bewegung 37 holen die Ausrichtflächen 14 die hintere Seitenfläche 7 nach Verlassen der Umlenkungen 21 im Bereich zwischen der ersten Hälfte und dem ersten Drittel der Trume 19 ein und legen sich an diese an, wobei sie zunächst noch nur über einen Teil ihrer Breite anliegen, während die Ausrichtflächen 13 noch im Abstand von den Seitenflächen 4, 5 liegen.2, the movements or movement components are specified as speed vectors, namely the oblique positioning movement of the alignment surfaces 13, 14 in the region of the run 19 with the arrow 35, the conveying movement of the conveyor 30 with the vector 36, the movement component lying parallel to the conveying direction 34 the alignment surfaces 13, 14 with the vector 37 and the movement component lying transversely to the conveying direction 34 with the vector 38. Because of the movement 37, which is faster than the movement 36, the alignment surfaces 14 fetch the rear side surface 7 in the region between the first half after leaving the deflections 21 and the first third of the strands 19 and lie against them, initially resting only over part of their width, while the alignment surfaces 13 are still at a distance from the side surfaces 4, 5.

Die Ausrichtflächen 14 schieben dann das Stückgut 2 auf dem als Gleitfläche wirkenden und mit der geringeren Geschwindigkeit 36 weiterlaufenden Transporteur 30 mit der größeren Geschwindigkeit 37 vor, wobei sie entlang der Seitenfläche 7 nach innen gleiten. Das Stückgut 2 ist zwar auf dem Transporteur 30 bereits vorausgerichtet, jedoch lediglich innerhalb größerer Toleranzen in Bezug auf die seitliche Ausrichtung quer zur Förderrichtung 34 sowie in Bezug auf seine Drehlage um eine zur Förderebene rechtwinklige Achse.The alignment surfaces 14 then advance the piece goods 2 on the conveyor 30, which acts as a sliding surface and continues to run at the lower speed 36, at the higher speed 37, sliding inwards along the side surface 7. The piece goods 2 are already pre-aligned on the conveyor 30, but only within larger tolerances with respect to the lateral orientation transverse to the conveying direction 34 and with respect to its rotational position about an axis perpendicular to the conveying plane.

Liegt das Stückgut 2 geringfügig verdreht auf dem Transporteur 30, so kommt zunächst nur eine der beiden Ausrichtflächen 14 in Eingriff mit der Seitenfläche 7 und verdreht das Stückgut 2 auf dem Transporteur 30 gleitend, bis auch die andere Ausrichtfläche 14 in Eingriff kommt, so daß vor der seitlichen Ausrichtung eine erste Drehausrichtung erfolgt. Liegt das Stückgut 2 quer zu den Seitenflächen 4, 5 versetzt auf dem Transporteur 30, so kommt noch im Bereich des unabgestützt freilaufenden Trums 19 nur eine der Ausrichtflächen 13 in Eingriff mit der zugehörigen Seitenfläche 4 bzw. 5 und verschiebt das Stückgut 2 auf dem Transporteur 30 gleitend in Richtung der anderen Seitenfläche 5 bzw. 4, wobei in diesem Fall keine ruhende Reibung überwunden werden muß, weil aufgrund der schnelleren Förderbewegung 37 bzw. der Drehbewegung bereits eine Relativbewegung zwischen Stückgut 2 und Transporteur 30 gegeben ist.
Während dieser Ausrichtphase kann der zwischen den Umlenkungen 20, 21 freilaufende Ausrichtkörper 16 bzw. 17 unter dem vom Stückgut 2 ausgehenden Ausrichtwiderstand geringfügig ausweichen, weil das Trum 19 unter dem Druck gegen die Ausrichtfläche 13 in die strichpunktiert angedeutete Bogenbahn überführt werden kann, aus welcher es bei Freigabe federnd in die geradlinig gestreckte Lage zurückkehrt.
If the piece goods 2 are slightly twisted on the conveyor 30, only one of the two alignment surfaces 14 comes into engagement with the side surface 7 and rotates the piece goods 2 on the conveyor 30 until the other alignment surface 14 also comes into engagement, so that the first alignment is done laterally. If the piece goods 2 lie transversely to the side surfaces 4, 5 offset on the conveyor 30, only one of the alignment surfaces 13 comes into engagement with the associated side surface 4 or 5 in the region of the unsupported free run 19 and displaces the piece goods 2 on the conveyor 30 sliding in the direction of the other side surface 5 or 4, in which case no static friction has to be overcome, because due to the faster conveying movement 37 or the rotary movement there is already a relative movement between piece goods 2 and conveyor 30.
During this alignment phase, the alignment body 16 or 17, which runs freely between the deflections 20, 21, can deviate slightly under the alignment resistance emanating from the piece goods 2, because the strand 19 can be transferred under the pressure against the alignment surface 13 into the arc path indicated by dash-dotted lines, from which it is when released, resiliently returns to the straight, straight position.

Aufgrund der schrägen Laufbahn des Ausrichtkörpers 16, zu welcher die Ausrichtfläche 13 etwa parallel und die Ausrichtfläche 14 etwa rechtwinklig liegt, kann die Ausrichtfläche 14 zunächst nur mit einem Teil ihrer Breite, nämlich im Anschluß an die Seitenfläche 4 bzw. 5 in Eingriff mit der Seitenfläche 7 gelangen, während danach die Ausrichtfläche 13 zunächst nur mit einem an ihr vorderes Ende anschließenden Teil ihrer Breite in Eingriff mit der zugehörigen Seitenfläche 4 bzw. 5 gelangt. Aufgrund der inneren Flexibilität des Tragorganes 18 bzw. aufgrund des Gelenkspieles zwischen den Kettengliedern kann der Ausrichtkörper 16, 17 aber auch so gelagert sein, daß er sich von selbst so auf die jeweilige Seitenfläche 4, 5, 7 einstellt, daß seine Ausrichtflächen 13, 14 bei der ersten Berührung parallel zur jeweils zugehörigen Seitenfläche ausrichtet werden. Hierzu kann der Ausrichtkörper 16 bzw. 17 z.B. um eine zu beiden Ausrichtflächen 13, 14 etwa parallele bzw. zur Grundfläche 11 etwa rechtwinkligen Kippachse 40 gegenüber dem Tragorgan 18 selbsteinstellend schwenkbar gelagert sein, wobei diese Kippachse 40 zweckmäßig in einem Bereich zwischen der Mitte der Breite der Ausrichtfläche 13 und deren Übergang in die Ausrichtfläche 14 liegt.Due to the oblique track of the alignment body 16, to which the alignment surface 13 is approximately parallel and the alignment surface 14 is approximately at right angles, the alignment surface 14 can initially only engage with the side surface with part of its width, namely following the side surface 4 or 5 7, while the alignment surface 13 initially only engages with a part of its width adjoining its front end with the associated side surface 4 or 5. Due to the internal flexibility of the support member 18 or due to the articulation between the chain links the alignment body 16, 17 can also be mounted such that it adjusts itself to the respective side surface 4, 5, 7 in such a way that its alignment surfaces 13, 14 are aligned parallel to the respectively associated side surface when they are first touched. For this purpose, the alignment body 16 or 17 can, for example, be pivotably mounted in a self-adjusting manner with respect to the support member 18 about a tilt axis 40 approximately parallel to the two alignment surfaces 13, 14 or approximately perpendicular to the base surface 11, this tilt axis 40 expediently in a range between the center of the width the alignment surface 13 and its transition into the alignment surface 14.

In der Bereitstellungslage liegt der Ausrichtkörper 16 bzw. 17 jedoch nicht im Bereich des freien Trums 19, sondern annähernd am Umfang der zugehörigen Umlenkung 20, so daß er hier gegen Bewegungen weg vom Stückgut 2 formschlüssig abgestützt ist. In der letzten Bewegungphase läuft der Ausrichtkörper 16, 17 nämlich unter der progressiv zunehmenden federnden Kraft auf die Umlenkung 20 auf, so daß er ggf. aus der strichpunktiert angedeuteten Bogenbahn mit einer erhöhten Ausrichtgeschwindigkeit 38 entlang dem Umfang der Umlenkung 20 zur genannten Mittelebene formschlüssig bewegt wird und dadurch in dieser letzten Bewegungsphase die genaue Ausrichtung zwangsläufig erfolgt. Wie die hinteren Umlenkungen 21 liegen auch die vorderen Umlenkungen 20 in einer gemeinsamen, zur Förderrichtung 34 etwa rechtwinkligen Axialebene 44, und in der Bereitstellungslage geht die Axialebene 44 durch die Ausrichtflächen 13, insbesondere etwa durch die Mitte von deren Breite, weshalb die Axialebene 44 gegenüber der in Bereitstellungslage stehenden Seitenfläche 7 geringfügig nach vorn versetzt ist.In the ready position, however, the alignment body 16 or 17 does not lie in the area of the free run 19, but approximately on the circumference of the associated deflection 20, so that it is supported here in a form-fitting manner against movements away from the piece goods 2. In the last phase of movement, the aligning body 16, 17 runs under the progressively increasing resilient force on the deflection 20, so that it is possibly moved form-fittingly from the arc path indicated by dash-dotted lines with an increased alignment speed 38 along the circumference of the deflection 20 to the mentioned central plane and in this last phase of movement the exact alignment is inevitable. Like the rear deflections 21, the front deflections 20 also lie in a common axial plane 44 which is approximately perpendicular to the conveying direction 34, and in the ready position the axial plane 44 passes through the alignment surfaces 13, in particular approximately through the middle of their width, which is why the axial plane 44 is opposite the side surface 7 in the ready position is slightly offset to the front.

Die Ausrichtkörper 16, 17 werden durch einen gemeinsamen Antrieb 39 synchron und gegeneinander in Förderrichtung 34 genau ausgerichtet angetrieben, wobei der Antrieb zweckmäßig auf die vorderen Umlenkungen 20 so wirkt, daß die Trume 19 gezogen werden. Der Antrieb 39 kann etwa in der Achse einer vorderen Umlenkung 20 liegen, und die Umlenkungen 20 können über ein nicht näher dargestelltes Getriebe schlupffrei miteinander antriebsverbunden sein.The aligning bodies 16, 17 are synchronized by a common drive 39 and mutually in the conveying direction 34 driven exactly aligned, the drive acting appropriately on the front deflections 20 so that the strands 19 are drawn. The drive 39 can lie approximately in the axis of a front deflection 20, and the deflections 20 can be connected to one another in a drive-free manner via a transmission (not shown in more detail).

Dem Antrieb 39 ist eine Steuervorrichtung 41 zugeordnet, welche die Bewegung der in Eingriff mit dem Stückgut 2 stehenden Ausrichtkörper 16, 17 dann stillsetzt, wenn die ausgerichtete Bereitstellungslage erreicht ist. In dieser Lage ist das Stückgut mit seiner vorderen Seitenfläche 6 gegen die Ausrichtfläche 12 aufgelaufen. Ist das Stückgut 2 bei diesem Auflauf eventuell noch geringfügig verdreht, so läuft es zunächst nur einseitig auf die Ausrichtfläche 12 auf und gleitet entlang dieser unter einer gleitenden ggf. weitere Drehung auf der Grundfläche 11, bis die Seitenfläche 6 ganzflächig an der Ausrichtfläche 12 anliegt. Gleichzeitig nimmt die Seitenfläche 6 die Ausrichtfläche 12 entgegen der Gegenkraft 29 mit, durch welche das Stückgut 2 gegen die Ausrichtflächen 14 gepreßt wird. Die Gegenkraft 29 kann auf die Ausrichtfläche 12 in Form beispielsweise einer vorgespannten Federkraft auch bereits in der Ausgangsstellung wirken, in welcher die Ausrichtfläche 12 durch das Stückgut 2 noch nicht belastet ist. Zur Antriebssteuerung ist auch eine Kurvensteuerung bzw. ein Kurvengetriebe mit einer Stillstandsphase denkbar. Von der Lage der Ausrichtfläche 12 kann ein Steuersignal abgeleitet werden, aufgrund dessen die Steuervorrichtung 41 die Ausrichtkörper 16, 17 genau bei Erreichen der ausgerichteten Bereitstellungslage stillsetzt, so daß diese Stillsetzung nicht durch einen vom Stückgut 2 ausgehenden Widerstand erfolgt.A drive device 41 is assigned to the drive 39, which stops the movement of the alignment bodies 16, 17 which are in engagement with the piece goods 2 when the aligned ready position is reached. In this position, the general cargo has its front side surface 6 against the alignment surface 12. If the piece goods 2 may still be slightly twisted during this casserole, it initially runs onto the alignment surface 12 only on one side and slides along this with a sliding, possibly further rotation, on the base surface 11 until the side surface 6 is in full contact with the alignment surface 12. At the same time, the side surface 6 takes the alignment surface 12 against the counterforce 29, by means of which the piece goods 2 are pressed against the alignment surfaces 14. The counterforce 29 can already act on the alignment surface 12 in the form of, for example, a prestressed spring force in the starting position, in which the alignment surface 12 is not yet loaded by the piece goods 2. A cam controller or cam gear with a standstill phase is also conceivable for drive control. A control signal can be derived from the position of the alignment surface 12, on the basis of which the control device 41 stops the alignment bodies 16, 17 exactly when the aligned ready position is reached, so that this shutdown does not take place through a resistance emanating from the piece goods 2.

In der Bereitstellungslage bilden die Ausrichtflächen 12 bis 14 einen zur Grundfläche 11 rechtwinkligen und gegenüber der Dicke des Stückgutes 2 wesentlich längeren Förderschacht, der im Bereich zweier einander quer gegenüberliegender Eckzonen durch verhältnismäßig schmale Winkelführungen, nämlich die Ausrichtflächen 13, 14, und im Bereich der davon entfernten Querfläche 6 durch eine ebene Gleitfläche, nämlich die Ausrichtfläche 12, begrenzt ist. Zwischen diesen Gleitflächen, die nur einen Bruchteil der Seitenflächen 4, 5, 7 einnehmen, liegt das Stückgut 2 völlig frei.In the ready position, the alignment surfaces 12 to 14 form a conveyor shaft which is perpendicular to the base surface 11 and is considerably longer than the thickness of the piece goods 2 and which in the area of two transversely opposite corner zones by relatively narrow angular guides, namely the alignment surfaces 13, 14, and in the area thereof distant transverse surface 6 is limited by a flat sliding surface, namely the alignment surface 12. The piece goods 2 are completely exposed between these sliding surfaces, which occupy only a fraction of the side surfaces 4, 5, 7.

Im Abstand oberhalb des Stückgutes 2 kann eine Einrichtung vorgesehen sein, durch welche ein Verpackungspapier oder dgl. in einer etwa eben ausgebreiteten Lage so bereitgehalten werden kann, daß es im Abstand oberhalb des oberen Endes des Schachtes etwa parallel zur Basisfläche 3 bzw. zur Deckfläche 8 liegt. Beim Anheben des ausgerichteten Stückgutes 2 mit dem Hubtisch 32 stößt dieses mit seiner Decklage 8 gegen die Unterseite des Packpapieres und nimmt dieses nach oben mit, so daß es nach unten seitlich über die Seitenflächen 4 bis 7 und dann an die Basisfläche 3 geschlagen werden kann, die wegen der begrenzten Größe der Grundfläche 11 im Randbereich frei liegt. Das vollständig aus dem offenen Ende des Förderschachtes herausgehobene und so umhüllte Stückgut 2 wird dann im Randbereich abgestützt, so daß der Hubtisch 32 wieder in seine Ausgangslage abgesenkt werden kann und dann in der beschriebenen Weise das nächste nachfolgende Stückgut 2 ausgerichtet übernimmt. Die Ausrichtkörper 15 bis 17 bilden somit einen aus einem aufgeweiteten Zustand in einen verengten Bereitstellungszustand überführbaren Gleitschacht, wobei die Verengungsbewegung der Ausrichtkörper 16, 17 in der beschriebenen Weise schräggerichtet ist und die Schachtbegrenzungen 12 bis 14 mit Vorspannung an mindestens zwei voneinander abgekehrten Seitenflächen 6, 7 anliegen können.A device can be provided at a distance above the piece goods 2, by means of which packaging paper or the like can be held ready in a position that is approximately flat, such that it is approximately parallel to the base surface 3 or the cover surface 8 at a distance above the upper end of the shaft lies. When the aligned piece goods 2 are lifted with the lifting table 32, its top layer 8 abuts against the underside of the wrapping paper and takes it upwards, so that it can be knocked down laterally over the side surfaces 4 to 7 and then onto the base surface 3, which is exposed due to the limited size of the base 11 in the edge area. The piece goods 2 completely lifted out of the open end of the conveying shaft and thus encased are then supported in the edge area, so that the lifting table 32 can be lowered back into its starting position and then takes over the next following piece goods 2 in the manner described. The aligning bodies 15 to 17 thus form a slide shaft which can be converted from an expanded state into a narrowed ready state, the narrowing movement of the aligning bodies 16, 17 being oriented obliquely in the manner described and the shaft boundaries 12 to 14 being pretensioned on at least two side surfaces 6, 7 facing away from one another can concern.

Die Tragorgane 18 und die Umlenkungen 20, 21 können hinter bzw. unter der Ebene der Grundfläche 11 bzw. der Förderebene des Transporteurs 30 liegen, so daß nur die Ausrichtkörper 16, 17 über diese Ebene frei vorstehen. Zweckmäßig sind die genannten Bauteile im wesentlichen verkapselt in einem Gehäuse 42 angeordnet, wobei zweckmäßig beiderseits der Förderbahn gesonderte Gehäuse für die beiden Ausrichteinheiten vorgesehen sind.The support members 18 and the deflections 20, 21 can lie behind or below the plane of the base 11 or the conveying plane of the transporter 30, so that only the alignment bodies 16, 17 protrude freely above this plane. The components mentioned are expediently essentially encapsulated in a housing 42, separate housings being expediently provided on both sides of the conveyor track for the two alignment units.

Liegen die genannten Bauteile vollständig unterhalb der Förderebene, so können die Ausrichtkörper 16, 17 durch Öffnungen in Stirnwänden dieser Gehäuse vorstehen. Es ist aber auch denkbar, das jeweilige Gehäuse 42 so auszubilden, daß es in seiner Umfangswandung einen Durchtritt 43 in Form einer Öffnung aufweist, durch welche der jeweilige Ausrichtkörper 16 bzw. 17 dann aus dem Gehäuse 42 austritt, wenn er sich über die Umlenkung 21 in den Bereich des Trums 19 bewegt, so daß der Ausrichtkörper 16 bzw. nur über den für die Ausrichtung wirksamen Stellweg außerhalb des Gehäuses liegt. Nach einem Teil des Umlaufes über die Umlenkung 20 tritt der Ausrichtkörper 16 bzw. 17 dann wieder in das Gehäuse 42 ein, in welchem er während des gesamten Rücklaufes entlang des gegenüberliegenden Trums liegt.If the components mentioned lie completely below the conveying plane, the alignment bodies 16, 17 can protrude through openings in end walls of these housings. However, it is also conceivable to design the respective housing 42 such that it has a passage 43 in the form of an opening in its peripheral wall, through which the respective alignment body 16 or 17 exits the housing 42 when it passes over the deflection 21 moved into the area of the strand 19, so that the alignment body 16 or only over the effective travel for alignment is outside the housing. After part of the circulation via the deflection 20, the alignment body 16 or 17 then re-enters the housing 42, in which it lies during the entire return along the opposite run.

Jeder der genannten Bauteile bzw. jede der Anordnungen kann nur ein einziges Mal oder zwei bzw. mehrfach vorgesehen sein, z.B. um in einer einzigen Positioniervorrichtung in einer oder mehreren Förderebenen bzw. in einer oder mehreren Ausrichtstationen gleichzeitig und/oder aufeinanderfolgend mehrere Stückgüter 2 auszurichten.Each of the named components or each of the arrangements can only be provided once, two or more times, e.g. in order to align several piece goods 2 simultaneously and / or in succession in a single positioning device in one or more conveying levels or in one or more alignment stations.
