Abstract

The invention relates to a device for aligning flat objects transported on a subsurface conveyor belt against a boundary arranged along the side of the subsurface conveyor strip, and for simultaneous pressing of the flat objects on the subsurface conveyor belt. The invention proposes that a continuous guiding band (2) moving at the same speed is arranged above the subsurface conveyor belt (1) and is twisted in such a manner many times on the side facing the subsurface conveyor belt (1) and is at such a distance from the subsurface conveyor belt (1) that guiding band (2) edges which extend obliquely towards the boundary and are between two respective twisted bends exert pressure and orienting forces on the flat objects (5).

GegenständenObjects
Beschreibungdescription
Die Erfindung betrifft eine Vorrichtung zum Ausrichten von auf einem Unterfiurband transportierten flachen Gegenstanden gemäß Oberbegriff des 1 PatentanspruchesThe invention relates to a device for aligning flat objects transported on a lower belt according to the preamble of claim 1
Bisher erfolgte das Ausrichten an der Begrenzung entweder mittels der Schwerkraft der flachen Gegenstande, was aber eine bestimmte Lage im Raum erforderlich macht, oder ausschließlich mittels Unterflurtransportband bzw Transportrollen, die schräg in Richtung Begrenzung angeordnet sind. Über dem Unterflurtransportband bzw den Transportrollen befindet sich dabei zum Vermeiden des Abhebens der Gegenstande ein gerade verlau¬ fendes Deckband in einem Abstand > der Dicke der zu transportierenden Gegenstande Ein Andrucken der Gegenstande auf das Unterflurtransportband bzw die schräg laufen¬ den Rollen mit dazwischen befindlichen Leitblechen erfolgt hierbei nicht, da dies den Ausrichteffekt behindern würde Aber selbst wenn das Deckband entsprechend dicht über dem Unterflurtransportband angeordnet würde, wäre ein Andrucken von sehr dün¬ nen Gegenstanden bei einem Wechsel von sehr dünnen und dickeren Gegenstanden aufgrund der Steifigkeit des Deckbandes nicht gewährleistet Dadurch können durch die unterschiedlichen Krafteinwirkungen beim Ausrichten Änderungen in der Nennge- schwindigkeit der Gegenstande auftreten, d h es können Luckenverschiebungen im Strom der Gegenstande entstehen Bringt man über dem Unterflurtransportband schräg angeordnete Andruckrollen an, so können zwar sich abwechselnde dicke und dünne Gegenstande angedrückt werden, eine sichere Funktion ist aber wegen des Schwing¬ verhaltens der gefederten Massesysteme der Andruckrollen nicht gewährleistetSo far, the alignment at the boundary has been done either by the gravity of the flat objects, but this requires a certain position in space, or exclusively by means of an underfloor conveyor belt or transport rollers, which are arranged obliquely in the direction of the boundary. To prevent the objects from being lifted, there is a straight cover band above the underfloor conveyor belt or the transport rollers at a distance> the thickness of the objects to be transported. The objects are pressed onto the underfloor conveyor belt or the diagonally running rollers with guide plates in between not here, since this would hinder the alignment effect. Even if the cover band were arranged appropriately close above the underfloor conveyor belt, printing on very thin objects would not be guaranteed when changing from very thin and thick objects due to the rigidity of the cover band the different effects of force when aligning changes in the nominal speed of the objects occur, ie gap gaps can occur in the flow of the objects If pressure rollers are arranged at an angle above the underfloor conveyor belt, alternating thick and thin objects can be pressed on, but a reliable function is not guaranteed because of the oscillating behavior of the sprung mass systems of the pressure rollers
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Ausrichten von auf ei¬ nem Unterflurband transportierten flachen Gegenstanden zu schaffen, die mit geringem Aufwand flache Gegenstande unterschiedlicher Dicke unabhängig von der Lage des Unterflurbandes an einer seitlich am Unterflurband entlang angeordneten Begrenzung ausrichtet, ohne daß es zu Luckenverschiebungen zwischen den Gegenstanden kommt Die Aufgabe wird erfindungsgemaß durch die Merkmale des Patentanspruchs 1 gelost Der Vorteil dieser Lösung liegt dann, daß das verdrillte Fuhrungsband einen einfachen mechanischen Aufbau benötigt, die Kanten des verdrillten Fuhrungsbandes die Gegen- stände aufgrund ihrer zur Begrenzung gerichteten Bewegungskomponente in Transport¬ richtung und des gewählten Abstandes des Fuhrungsbandes vom Transportband die Gegenstande gleichzeitig auf das Transportband drucken und an der Begrenzung aus¬ richten Dadurch werden beim Ausrichtvorgang Luckenverschiebungen zwischen den Gegenstanden verhindert Das Andrucken und Ausrichten erfolgt zwischen den Verdnll- knoten von der Seite betrachtet, so daß auch sehr dünne und dickere Gegenstände im Wechsel auf dem Transportband befindliche Gegenstande sicher angedruckt und aus¬ gerichtet werdenThe invention has for its object to provide a device for aligning flat objects transported on an underfloor belt which, with little effort, aligns flat objects of different thicknesses regardless of the position of the underfloor belt at a boundary arranged laterally along the underfloor belt, without it Gaps are shifted between the objects. The object is achieved according to the invention by the features of patent claim 1 The advantage of this solution is that the twisted guiding belt requires a simple mechanical construction, the edges of the twisted guiding belt push the objects onto the conveyor belt due to their movement component in the direction of transport directed to the limitation and the selected distance of the guiding belt from the conveyor belt Print and align to the boundary. This prevents gaps in the alignment between the objects during the alignment process. The printing and aligning takes place between the thinning nodes viewed from the side, so that even very thin and thicker objects can be printed and alternately on the conveyor belt be aligned
Dabei ist es vorteilhaft, gemäß Patentanspruch 2 die Kanten des Fuhrungsbandes zur Erzielung einer größeren Haftreibung strukturiert auszufuhren In einer weiteren vorteilhaften Auskleidung gemäß Patentanspruch 3 besteht die Begren¬ zung aus einem mit der Geschwindigkeit des Unterflurbandes in Transportrichtung lau¬ fendem Begrenzungsband, wodurch Reibungen an der Begrenzung weitgehend vermie¬ den werden Optional kann zur Verstärkung des Ausrichteffektes gemäß Patentanspruch 4 das Unter- flurband schräg in Richtung Begrenzung angeordnet werdenIt is advantageous, in accordance with claim 2, to structure the edges of the guide belt in order to achieve greater static friction. In a further advantageous lining according to claim 3, the limitation consists of a limiting belt running at the speed of the underfloor belt in the direction of transport, which causes friction on the Limitation largely avoided The underfloor belt can optionally be arranged obliquely in the direction of the limitation in order to reinforce the alignment effect
In einem Beispiel wird die Erfindung nun anhand der Zeichnungen naher erläutert Dabei zeigenIn an example, the invention will now be explained in more detail with reference to the drawings

FIG. 3 shows a top view of the device according to the invention with the underfloor band obliquely in the direction of the limiting band
In diesem Ausführungsbeispiel wird die erfindungsgemaße Vorrichtung zum Ausrichten von Postsendungen wie Briefe, Karten u a als flache Gegenstande eingesetzt Zwi¬ schen Deckbandern 3 erfolgt der Transport der Briefe 5 zur Vorrichtung zum Ausrichten und von der Vorrichtung weg Dabei laufen die Briefe 5 auf ein Unterflurband 1 Damit die Briefe 5 beim Ausrichten eine sichere Unterlage haben, ist das Unterflurband 1 brei- ter als die Deckbander 3 Über dem Unterflurband 1 lauft ein endloses Fuhrungsband 2 mit der gleichen Ge¬ schwindigkeit in Transportrichtung, das wie dargestellt zwischen den Umlenkrollen auf der dem Unterflurband 1 zugewandten Seite so verdrillt ist, daß die die Briefe 5 berüh¬ renden Kanten in Richtung eines seitlich am Unterflurband 1 entlang angeordneten, zum Unterflurband 1 senkrechten Begrenzungsband 4 laufen Dieses Begrenzungsband 4 bewegt sich mit der gleichen Geschwindigkeit in Transportrichtung wie das UnterflurbandIn this exemplary embodiment, the device according to the invention for aligning mail items such as letters, cards and the like is used as flat objects. Between the cover bands 3, the letters 5 are transported to the device for aligning and away from the device. The letters 5 run on an underfloor belt 1 the letters 5 have a secure base during alignment, the underfloor band 1 is wider than the cover band 3 An endless guide belt 2 runs over the underfloor belt 1 at the same speed in the transport direction, which, as shown, is twisted between the deflection rollers on the side facing the underfloor belt 1 such that the edges touching the letters 5 move in the direction of a side of the underfloor belt 1 along limiting belt 4 arranged perpendicular to the underfloor belt 1 This limiting belt 4 moves at the same speed in the transport direction as the underfloor belt
1 Dadurch werden an der Ausrichtflache auftretende Reibungskräfte vermieden Durch die Einklemmung der Briefe 5 zwischen Unterflurband 1 und Fuhrungsband 2 wer¬ den alle Sendungen mit Nenngeschwindigkeit transportiert, d h Veränderungen in den Abstanden zueinander treten nicht auf Darüber hinaus wird über das Fuhrungsband 2 in die Bnefe 5 eine Kraft quer zur Transportrichtung eingeleitet, wodurch die Briefe 5 zum Begrenzungsband 4 hin abgelenkt werden Quersteifigkeit und Breite des Fuhrungsbandes 2, Anzahl der Knoten, Abstand des Fuh¬ rungsbandes 2 zum Unterflurband 1 , Reibkoeffizienten der Bander gegenüber den zu transportierenden Gegenstanden sowie die Gestaltung der Rander des Fuhrungsbandes1 Frictional forces occurring on the alignment surface are thereby avoided. By clamping the letters 5 between the underfloor belt 1 and the guide belt 2, all mail items are transported at nominal speed, ie changes in the spacing from one another do not occur a force is introduced transversely to the direction of transport, whereby the letters 5 are deflected towards the limiting band 4, transverse rigidity and width of the guiding band 2, number of knots, distance of the guiding band 2 from the underfloor band 1, coefficient of friction of the band against the objects to be transported and the design of the Edge of the leader tape
2 (z B Sagezahnform) werden so aufeinander abgestimmt, daß dicke und dünne Ge¬ genstande in wechselnder Reihenfolge immer eingeklemmt sind und zum Begrenzungs- band 4 transportiert werden, wobei instabile Gegenstande nach Erreichen des Begren¬ zungsbandes 4 nicht gefaltet werden Zur Unterstützung des Quertransportes der Briefe 5 zum Begrenzungsband 4 hm ist gemäß Fig 3 das Unterflurband 1 zusatzlich schräg in Richtung Begrenzungsband 4 angeordnet 2 (eg sawtooth shape) are matched to one another in such a way that thick and thin objects are always clamped in an alternating sequence and are transported to the limiting band 4, wherein unstable objects are not folded after reaching the limiting band 4 to support the transverse transport of the letters 5 to the boundary band 4 hm, according to FIG. 3, the underfloor band 1 is additionally arranged obliquely in the direction of the boundary band 4
