Description

Die Erfindung betrifft eine Transporteinrichtung zur Umlenkung von flachen Sendungen gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a transport device for deflection of flat shipments according to the preamble of the claim 1.

In Sortieranlagen werden Sendungen nach verschiedenen Kriterien sortiert. Kriterien können beispielsweise Adressen oder Barcodes sein. In den Sortiermaschinen werden die flachen Sendungen eingeklemmt zwischen Deckbändern, die aus einem Unter- und einem Oberband bestehen, transportiert. Um die jeweiligen Sortierkriterien zu identifizieren, werden die Sendungen an speziellen Kameras vorbeigeführt. Dort werden die Verteilinformationen aufgenommen und einer Auswerteelektronik zugeführt. Da für die Auswertung eine bestimmte Zeit notwendig ist, können die Sendungen erst nach Ablauf dieser Zeit mit Hilfe von Weichen sortiert werden. Diese Bearbeitungszeit wird gewährleistet, indem die Sendungen nach der Kamera in Abhängigkeit von der benötigten Auswertezeit mehr oder weniger lange Transportstrecken durchlaufen. In diesen Transportstrecken sind Umlenkungen des Deckbandlaufes erforderlich, um den Platzbedarf gering zu halten.Shipments are sorted according to various criteria in sorting systems sorted. For example, criteria can be addresses or Be barcodes. In the sorting machines, the flat ones Consignments jammed between cover tapes that come from a sub- and consist of an upper band. To the respective The consignments are used to identify sorting criteria guided past special cameras. There are the Distribution information recorded and an evaluation electronics fed. Because a certain time is necessary for the evaluation the shipments can only after this time are sorted using turnouts. This processing time is ensured by the shipments after the camera in More or less depending on the evaluation time required go through long transport routes. In these transport routes deflections of the cover tape run are required, to keep the space requirement low.

Nach DE 44 37 114 C1 erfolgt die Umlenkung über Umlenkrollen. Das Oberband wird um eine Haupttrommel geführt. Das Unterband wird über eine Nebentrommel an der Haupttrommel vorbeigeleitet und die Sendungen werden zwischen Oberband und Haupttrommel befördert. Benötigt man aufgrund des Sendungsspektrums große Umlenkradien, um starke Biegebeanspruchungen zu vermeiden, so sind Trommeln mit großen Durchmessern, die nur mit hohem Aufwand herstellbar sind und bei einer 180°-Umlenkung doppelt soviel Platz wie notwendig brauchen. (Es wird nur der Halbkreis benötigt.) According to DE 44 37 114 C1, the deflection takes place via deflection rollers. The upper belt is passed around a main drum. The lower band is led past the main drum via a secondary drum and the shipments are between the upper band and main drum promoted. One needs because of the program spectrum large deflection radii in order to avoid strong bending stresses So are drums with large diameters that only come with high effort can be produced and with a 180 ° deflection need twice as much space as necessary. (It will only be the Semicircle needed.)

Eine weitere Variante zur Realisierung einer Umlenkung besteht gemäß DE 196 12 525 darin, eine Kurvenbahn aus einzelnen Rollen zu bilden. Die Flachriemen werden durch die Rollenkurve umgelenkt. Nachteilig hierbei sind die hohen Kosten infolge einer hohen Rollenzahl. Eine Reduzierung der Anzahl der Rollen hat einen Polygoneffekt zur Folge, der die Sendungen beim Durchfahren der Kurve stark strapaziert und zu zusätzlichen Lückenverschiebungen führt. Bei Sendungen mit Durchschlagpapier (z.B. Formulare, Rechnungen) kann es auch zur Unleserlichkeit der Formulare oder Rechnungen führen.Another variant for realizing a redirection exists according to DE 196 12 525 therein, a curved track made up of individual To form roles. The flat belts are through the roller curve diverted. The disadvantage here is the high cost due to a high number of roles. A reduction in the number the reel has a polygon effect that the broadcasts heavily stressed when driving through the curve and additional Gap shifts leads. For shipments with Carbon paper (e.g. forms, invoices) can also make the forms or invoices illegible.

Der im Anspruch 1 angegebenen Erfindung liegt also das Problem zugrunde, eine kostengünstige und platzsparende Transporteinrichtung für flache Sendungen zum Umlenken zu schaffen, bei welcher die Sendungen möglichst gering beansprucht werden.The invention specified in claim 1 is therefore the problem based on an inexpensive and space-saving transport device create for flat shipments to redirect, where the shipments are used as little as possible become.

Durch die Führung des aus einem endlosen Unterband und einem endlosen Oberband bestehenden Deckbandsystems über das feststehende Führungselement mit einer als Kurvensegment geformten Gleitfläche, die Wahl unterschiedlicher Reibwerte wurde eine technisch Lösung geschaffen, die bei einem großen Umlenkradius und damit einer geringen Biegebeanspruchung eine geringe Tiefe beansprucht, bei geringem Fertigungsaufwand.By guiding the from an endless sub-band and one endless top band existing shroud system over the fixed Guide element with a shaped as a curve segment Sliding surface, the choice of different coefficients of friction was made created a technical solution with a large deflection radius and thus a low bending stress shallow depth, with little manufacturing effort.

Vorteilhafte Ausführungen sind in den Unteransprüchen dargestellt.Advantageous designs are presented in the subclaims.

Das außen befindliche Oberband muß bei einer gegebenen Transportgeschwindigkeit gegenüber dem Unterband einen größeren Weg zurücklegen. Damit die dadurch auftretenden Relativgeschwindigkeiten ausgeglichen werden können, ohne die flachen Sendungen zu verschieben und zu beanspruchen, ist die innen laufende Seite des Oberbandes gemäß Anspruch 2 mit einem niedrigen Reibwert ausgestattet.
Weiterhin ist es vorteilhaft, gemäß Anspruch 3 das Kurvensegment als Kreissegment auszuführen. The upper belt located outside must travel a greater distance than the lower belt at a given transport speed. So that the resulting relative speeds can be compensated for without shifting and stressing the flat mail items, the inside running side of the upper belt is equipped with a low coefficient of friction.
Furthermore, it is advantageous to design the curve segment as a circular segment.

Um ein unkontrolliertes Weglaufen der Bänder auf der Führungsfläche zu verhindern, wird das Unterband gemäß Anspruch 4 mittels einer Längsnut in der Gleitfläche des Führungselementes geführt.To prevent the tapes from running away in an uncontrolled manner on the guide surface to prevent the sub-band according to claim 4 by means of a longitudinal groove in the sliding surface of the guide element guided.

Darüber hinaus ist es vorteilhaft, gemäß Anspruch 5 die Gleitfläche des Führungselementes antistatisch auszuführen.In addition, it is advantageous, according to claim 5 Execute sliding surface of the guide element antistatic.

Gemäß Anspruch 6 sind an den Enden des Führungselementes Ausrichtstrecken angeordnet, um eventuelle Schräglagen auszugleichen. Gleichzeitig wird die Aufnahme und Übergabe der Sendungen durch den breiteren Spalt zwischen den Umlenkrollen für Ober- und Unterband erleichtert.According to claim 6 are at the ends of the guide element alignment arranged to compensate for any inclined positions. At the same time, the inclusion and handover of the Shipments through the wider gap between the pulleys relieved for upper and lower band.

Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnung näher erläutert.The invention is then described in an exemplary embodiment explained in more detail with reference to the drawing.

Dabei zeigt FIG 1 eine perspektivische Ansicht einer Transporteinrichtung zur 180°-Umlenkung. Ein Unterband 1 und ein Oberband 2 werden über ein feststehendes Führungselement 3 mit glatter, einen geringen Reibwert aufweisender Gleitfläche in Form eines Kurvensegmentes, in diesem Fall ein Kreissegment, geführt und dadurch umgelenkt. Das innen laufende Unterband 1 wird durch eine innerhalb des Führungselementes 3 befindliche Antriebsrolle 5 angetrieben. Über Umlenkrollen 7 erfolgt eine Umlenkung des Unterbandes 1 derart nach innen, daß die Antriebsrolle 5 in dem Maße vom Unterband 1 mit der den Sendungen 6 zugewandten Seite, die zur Sicherung einer sicheren und rutschfreien Sendungsmitnahme einen hohen Reibwert aufweist, umschlungen wird, daß ein weitgehend schlupffreier Antrieb gewährleistet ist. Dazu ist auch eine bestimmte Riemenspannung aufrechtzuerhalten.
Zum Führungselement 3 gerichtet, hat das Unterband 1 einen geringen Reibwert, so daß das Unterband 1 leicht und ohne Verschleiß.über das Führungselement 3 rutscht. Damit das Unterband 1 auf dem Führungselement 3 nicht nach oben oder unten weglaufen kann, muß es geführt werden. Aus diesem Grunde befindet sich das in der Gleitfläche des Führungselementes 3 eine Längsnut und das Unterband 1 auf der dem Führungselement 3 zugewandten Seite einen Längsauftrag 8 in Form einer Leiste, der in der Längsnut geführt wird. Das Oberband 2, das auf dem Unterband 1 um das Führungselement 3 geführt ist, wird auch durch dieses angetrieben. Zwischen beiden eingeklemmt, befinden sich die Sendungen 6. Da die Sendungen 6 unterschiedliche Dicken besitzen, eine Klemmung aber trotzdem gesichert werden muß, ist das Oberband 2 längs-elastisch ausgeführt, so daß es sich den unterschiedlichen Konturen anpassen kann und eine Klemmung auch bei wechselnden Sendungsdikken garantiert ist.
Bei der geometrischen Gestaltung der Gleitfläche des Führungselementes 3, z.B. bei der Wahl des Umlenkradius ist folgendes zu beachten:
Besonders dicke und/oder steife Sendungen können sich bei zu klein gewähltem Radius nicht komplett an die Gleitfläche 3 anlegen und führen so zu einem zusätzlichen Abheben des elastischen Oberbandes 2 vom Unterband 1. Werden im Wechsel sehr dünne und sehr dicke und steife Sendungen 6 bei minimalen Lücken transportiert, so kann es bei zu kleinem Radius zum Loslassen der dünnen Sendungen 6 kommen, was unzulässige Lükkenverschiebungen zur Folge hat.1 shows a perspective view of a transport device for 180 ° deflection. A lower belt 1 and an upper belt 2 are guided over a fixed guide element 3 with a smooth, low-friction sliding surface in the form of a curved segment, in this case a circular segment, and thereby deflected. The inner lower belt 1 is driven by a drive roller 5 located within the guide element 3. The lower belt 1 is deflected inwards by means of deflection rollers 7 in such a way that the drive roller 5 is wrapped to the extent of the lower belt 1 with the side facing the mail items 6, which has a high coefficient of friction to ensure safe and non-slip mail take-up, that largely slip-free drive is guaranteed. A certain belt tension must also be maintained.
Facing the guide element 3, the lower belt 1 has a low coefficient of friction, so that the lower belt 1 slips easily and without wear over the guide element 3. So that the lower belt 1 cannot run up or down on the guide element 3, it must be guided. For this reason, there is a longitudinal groove in the sliding surface of the guide element 3 and the lower band 1 on the side facing the guide element 3 is a longitudinal application 8 in the form of a strip which is guided in the longitudinal groove. The upper belt 2, which is guided on the lower belt 1 around the guide element 3, is also driven by this. Pinched between the two, there are the mailings 6. Since the mailings 6 have different thicknesses, but a clamp must still be secured, the upper belt 2 is designed to be longitudinally elastic so that it can adapt to the different contours and a clamp even with changing ones Consignment thickness is guaranteed.
When designing the sliding surface of the guide element 3, for example when choosing the deflection radius, the following must be observed:
Particularly thick and / or stiff mail items cannot set themselves completely against the sliding surface 3 if the radius is selected too small and thus lead to an additional lifting of the elastic top band 2 from the bottom band 1. Alternately, very thin and very thick and stiff mail items 6 with minimal If gaps are transported, the thin mail items 6 can be released if the radius is too small, which results in inadmissible displacements in the gap.

Die Gleitfläche des Führungselementes 3 hat folgende Eigenschaften:

  • 1. niedriger Reibwert gegenüber dem Unterband 1 und den Sendungen 6;
  • 2. optimal glatte Oberfläche zur Gewährleistung eines verschleißfreien und geräuscharmen Gleitvorganges;
  • 3. verschleißresistent und vorzugsweise antistatisch.
    • The sliding surface of the guide element 3 has the following properties:
  • 1. low coefficient of friction compared to the lower belt 1 and the consignments 6;
  • 2. optimally smooth surface to ensure a wear-free and low-noise sliding process;
  • 3. wear-resistant and preferably antistatic.

    • Da das Oberband 2 gegenüber dem Unterband 1 bei gegebener Geschwindigkeit einen größeren Weg zurücklegen muß (die neutrale Faser läuft auf dem größeren Radius), weist die innen anliegende Seite des Oberbandes 2 einen niedrigen Reibwert auf. So können die zwangsläufig auftretenden Relativgeschwindigkeiten ausgeglichen werden, ohne dabei die Sendungen 6 zu beanspruchen und zu verschieben.Since the upper belt 2 compared to the lower belt 1 at a given speed have to go a long way (the neutral one Fiber runs on the larger radius), has the inner one Side of the upper belt 2 on a low coefficient of friction. So the inevitably occurring relative speeds can be compensated without claiming the consignments 6 and move.

    Das Führungselement 3 ist nicht als vollständiger Halbkreis ausgeführt, sondern als Kreissegment. Den Enden des Führungselementes 3 sind Ausrichtstrecken 8 vor- bzw. nachgelagert. Diese bestehen jeweils aus zwei aufrecht stehenden Leitblechen und einem Unterflurband. Am Ausgang bzw. Eingang der Ausrichtstrecken 8 befinden sich die Umlenkrollen für Ober- und Unterband, wobei diese in einem solchen Abstand voneinander angeordnet sind, daß die Sendungen zwischen Ober- und Unterband nicht geklemmt sind, d.h. in diesen Bereichen werden die Sendungen am Unterflurband ausgerichtet und durch dieses transportiert.The guide element 3 is not a complete semicircle executed, but as a segment of a circle. The ends of the guide element 3 are alignment lines 8 upstream or downstream. These consist of two upright baffles and an underfloor belt. At the exit or entrance of the Alignment sections 8 are the deflection rollers for upper and subband, these at such a distance from each other are arranged that the programs between the upper and lower band are not clamped, i.e. in these areas the shipments aligned on and through this underfloor belt transported.
