Abstract

The invention relates to a routing installation for flat objects with a vertical or slightly inclined plane for the mail route and the routing compartments, where the purpose oriented and prior art functional groups are arranged laterally near the routing compartment wall in the desired configuration and where the despatches arrive standing on their narrow end and in a plane perpendicular to the routing plane for sorting and distribution. Here the sorting rate is to be uniformly high. According to the invention, the despatches standing on the lower narrow edge are sorted downwards. Here, the sorting device is designed in such a way that suitable retainers prevent undesired sorting through the despatches weight or conveying forces. Sorting preferably takes place at constant adjustable gaps via gap measurement.

Description

Verteilanlage für flache Gegenstände Distribution system for flat objects

Die Erfindung betrifft eine kompakte Verteilanlage für flache Gegenstände, wie Post- Sendungen, nach dem Oberbegriff des Patentanspruches 1.The invention relates to a compact distribution system for flat objects, such as mail items, according to the preamble of claim 1.

Um der Forderung nach immer leistungsfähigeren Verteilanlagen bei möglichst geringer Standfläche gerecht zu werden, wurden Verteilanlagen mit senkrechter oder etwas dazu geneigter Brieflaufebene geschaffen. Die aufgabengemäß vorhandenen und an sich bekannten Baugruppen, wie z. B. Adreßleser, Barcodeleser, Barcodedrucker, Vereinzeier, Weichen, Speicher- oder Verzögerungsstrecken befinden sich je nach Kun¬ denanforderung rechts und/ oder links von den Verteilfächern, in welche die Sendun¬ gen sortiert werden (Jp-Publ.-no. 07088430A; 1 oshiba Letter sorting machine TR 52, TR ό2, 1985). Bei diesen bekannten Sendungsverteilanlagen werden die Sendungen nach oben abgezogen. Da die Sendungen aufgrund ihrer Schwerkraft auf die schmale Kante nach unten ausgerichtet werden und im Normalfall unterschiedliche Längen aufweisen kann hierbei u. a. nur auf konstante Vorder- oder Hinterkante vereinzelt werden. Das hat wiederum ungleichmäßige Lücken zwischen den Sendungen und somit relativ ge¬ ringe Durchsätze zur Folge. Diesen Mangel versucht man bei den bekannten Anlagen mit einer Vorsortierung nach einheitlichen Sendungslängen zu beheben, was aber sehr aufwendig ist und nur bei größeren Stückzahlen gleicher Länge angewendet werden kann.In order to meet the demand for ever more efficient distribution systems with the smallest possible footprint, distribution systems with vertical or somewhat inclined letter flow levels were created. The task existing and known modules such. B. Address readers, barcode readers, barcode printers, separators, switches, memory or delay lines are located to the right and / or left of the distribution compartments, depending on the customer requirements, into which the items are sorted (JP-Publ. No. 07088430A; 1 oshiba letter sorting machine TR 52, TR ό2, 1985). In these known mail distribution systems, the mail items are deducted upwards. Since the mailings are oriented downwards on the narrow edge due to their gravity and normally have different lengths, this can include: a. only be separated on a constant leading or trailing edge. This in turn results in uneven gaps between the mail items and thus relatively low throughputs. This deficiency is tried in the known systems with a presorting according to uniform shipment lengths, which is very complex and can only be used for larger quantities of the same length.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine kompakte Vertei- lanlage für flache Gegenstände zu schaffen, bei der eine Vereinzelung der Gegen¬ stände mit gleichmäßig geringer Lücke zwischen den Gegenständen und damit möglichst hohem Durchsatz ohne Vorsortierung und notwendiges a priori Wissen über die Gegenstände möglich ist. Erfindungsgemäß wird die Aufgabe durch die Merkmale des Patentanspruches 1 gelöst. Das Vereinzeln nach unten erfordert dabei eine Vereinzelungseinrichtung, die ein un¬ gewolltes Vereinzeln aufgrund der Sendungsschwerkraft oder aufgrund von Mitnah¬ mekräften verhindert.The present invention is therefore based on the object of providing a compact distribution system for flat objects, in which the objects are separated with a uniformly small gap between the objects and thus the highest possible throughput without pre-sorting and necessary prior knowledge about the objects is possible. According to the invention the object is solved by the features of claim 1. The separation downwards requires a separation device that prevents unwanted separation due to the gravity of the mail item or due to entraining forces.

Vorteilhafte Ausgestaltung der Erfindung sind in den Unteransprüchen angegeben. In der Ausgestaltung nach Patentanspruch 2 erfolgt die Vereinzelung nach unten auf kon- stante einstellbare Lücke über eine Lückenmessung.Advantageous embodiments of the invention are specified in the subclaims. In the embodiment according to claim 2, the separation is carried out down to a constant adjustable gap by means of a gap measurement.

Da die Gegenstände (Sendungen) auf die unter schmale Kante ausgerichtet sind, kann bei einem Vereinzeln nach unten mit geringem Aufwand über eine Lückenmessung auf konstante Lücke abgezogen werden. Dieser Vorgang erfolgt mittels an sich bekannterSince the objects (items) are aligned with the narrow edge, they can be subdivided downwards with little effort using a gap measurement to a constant gap. This process is carried out by means known per se

ERSATZBLAH (REGEL 26) Verfahren wie: Messung der Hinterkante der abgezogenen Sendung und Neuabzug nach Ablauf einer der Lücke entsprechenden Taktzahl bei bekannter Abzugsgeschwin¬ digkeit oder Feststellen des Ortes der Hinterkante der abgezogenen Sendungen mittels einer Lichtschrankenzeile (DE-PS 2013201, DE-PS 2712907; DE-OS 3424397). Damit wird ein für jede Sendungslänge möglichst hoher Durchsatz erreicht.ERSATZBLAH (RULE 26) Methods such as: measurement of the trailing edge of the deducted item and new deduction after a number of cycles corresponding to the gap at known deduction speed or determination of the location of the trailing edge of the deducted items using a light barrier line (DE-PS 2013201, DE-PS 2712907; DE-OS 3424397 ). This achieves the highest possible throughput for each shipment length.

Um eine sichere Vereinzelung nach unten zu gewährleisten, weist die Vereinzelungs¬ einrichtung gemäß der vorteilhaften Ausführung nach Patentanspruch 3 im Start-Stop- Betrieb laufende Abzugsbänder mit Reiboberfläche und Saugöffnungen sowie federnd gelagerte Abstreifer auf (DE-PS 2704045, DE-OS 4328434).In order to ensure a safe separation downwards, the separating device according to the advantageous embodiment according to claim 3 in the start-stop operation has running belts with a friction surface and suction openings as well as spring-mounted wipers (DE-PS 2704045, DE-OS 4328434).

In einer weiteren vorteilhaften Ausführung nach Patentanspruch 4 befinden sich benö¬ tigte Speicher- oder Verzögerungsstrecken, welche die für die online-Verarbeitung notwendigen Adreßerkennungszeiten sicherstellen, oberhalb und / oder unterhalb der Fachwand, so daß die Anlage möglichst kurz gehalten werden kann.In a further advantageous embodiment according to claim 4, the memory or delay lines required, which ensure the address recognition times required for online processing, are located above and / or below the compartment wall, so that the system can be kept as short as possible.

Die Erfindung wird nachfolgend in einem Ausführungsbeispiel anhand von Zeich¬ nungen näher erläutert. Dabei zeigenThe invention is explained in more detail below in an exemplary embodiment with reference to drawings. Show

Bei der als Beispiel gewählten Offline-Rechtsversion werden die im Stapel angeliefer¬ ten Sendungen, z. B. Briefe manuell auf eine Stoffeingabeeinheit 1 1 eingelegt und dabei möglichst gut auf die Unter- und Hinterkante ausgerichtet. Durch eine Vakuum-Reibe- Vereinzelungseinrichtung 1 werden die Briefe aus dem Stapel mit konstanter Lücke nach unten vereinzelt. In einer Formaterkennung, bestehend aus einer Steifig- keitsmeßeinrichtung 2, einer Höhenmeßeinrichtung 3 und einer Dickenmeßeinrich¬ tung 4, wobei die Brieflänge mittels Lichtschranke der Vereinzelungseinrichtung er¬ mittelt wird, werden die nichtmaschinenfähigen Briefe erkannt und mit Hilfe einer Format-Weiche 5 aus dem Briefstrom ausgesondert und in einer Reject-Box 7 gesam¬ melt.In the offline legal version chosen as an example, the mail items delivered in the stack, e.g. B. Letters manually placed on a fabric input unit 1 1 and aligned as well as possible on the bottom and rear edge. The letters from the stack are separated with a constant gap downwards by means of a vacuum grater separating device 1. In one format detection, consisting of a rigidity keitsmeßeinrichtung 2, a height measuring device 3 and a Dickenmeßeinrich ¬ tung 4, wherein the letter length by a light barrier of the separating device it ¬ averages is, the non-machine capable letters will be detected and with the aid of a format shunt 5 from the stream of letters separated out and collected in a reject box 7.

Der Briefstrom maschinenfähiger Sendungen wird in einer Richtstrecke 6 auf die lange Unterkante parallel zur Brieflaufebene ausgerichtet, damit in den Folgeeinheiten keine Probleme mit verdrehten Briefen auftreten. Durch einen Scanner 8 werden alle Teile der Adresse aufgenommen, die für den automatischen Anschriftenleser notwendig sind, um die Briefadresse eindeutig zu erfassen. Sendung die schon einmal bearbeitet wurden und einen Identifizierungs (ID)-Code oder einen Barcode haben, werden von einem ID-Leser 9 bzw. einen Barcode-Leser 10 gelesen.The letter stream of machine-compatible mail items is aligned in a straightening section 6 on the long lower edge parallel to the letter travel level, so that no problems with twisted letters occur in the subsequent units. With a scanner 8 all parts the address that is necessary for the automatic address reader to uniquely record the letter address. Mail items that have already been processed and have an identification (ID) code or a bar code are read by an ID reader 9 or a bar code reader 10.

Maschinenfähige Sendungen, die nicht gelesen werden konnten oder eine zu kleine Lücke haben, werden durch eine Reject-Weiche 12 in ein Reject-Fach 13 gestapelt und können erneut eingegeben werden. Mittels einer Transport- und Speicherstrecke 14 werden die Sendungen zu einem Druck-Modul transportiert, wo sie in einer weiteren Richtstrecke 15 nochmals auf die Längskante parallel zur Bandlaufebene ausgerichtet werden, um den ID-Code bzw. den Barcode durch nachfolgende ID-Code-Drucker lό und Barcode-Drucker 17 in einem engen Toleranzfeld auf die Briefe zu drucken. Die aufgedruckten Daten werden dann durch eine ID-Code-Kontrolleinrichtung 18 bzw. eine Barcode-Kontrolleinrichtung 19 überprüft. In einer nachfolgenden Trocken- strecke 20 wird der Druck getrocknet, um ein Verwischen zu verhindern.Machine-compatible items that could not be read or that have a gap that is too small are stacked by a reject switch 12 into a reject compartment 13 and can be re-entered. The consignments are transported to a printing module by means of a transport and storage section 14, where they are again aligned in a further straightening section 15 on the longitudinal edge parallel to the strip travel plane, around the ID code or the bar code by subsequent ID code printers lό and barcode printer 17 to print on the letters in a narrow tolerance range. The printed data are then checked by an ID code control device 18 or a barcode control device 19. The print is dried in a subsequent drying section 20 in order to prevent blurring.

Um Stapelprobleme zu minimieren, werden in einem Überlapper 21 Sendungen glei¬ cher Zieladresse überlappt und in diesem Zustand verteilt. Je nach Zieladresse werden die Sendungen in die jeweils horizontalen Transportstrecken 22 geleitet, um dann im entsprechenden Fach 23 abgestapelt zu werden.In order to minimize stacking problems, 21 items of the same destination address are overlapped in an overlap and distributed in this state. Depending on the destination address, the mail items are routed into the respective horizontal transport routes 22 in order to then be stacked in the corresponding compartment 23.

Neben dieser beispielhaften Maschinenkonfiguration sind je nach Kundenanforderung auch andere Varianten wie Offline-Links-Maschine NTS Online-Maschinen NTS Rechts¬ oder Links-Versionen, Barcodesorter BCS Rechts- und Links-Version möglich. Dies ist in der Fig. 2 schematisch dargestellt.In addition to this exemplary machine configuration, other variants such as offline left machine NTS online machines NTS right or left versions, bar code sorters BCS right and left versions are also possible, depending on customer requirements. This is shown schematically in FIG. 2.

Um eine einheitliche vorteilhafte Stapelrichtung in der Fachwand, bei einheitlicher Ausrichtung in der Vereinzelungseinrichtung zu erreichen, z. B. Briefseite mit Adresse und Briefmarke nach oben, ist bei den Rechtsversionen eine Transportstrecke 14 not¬ wendig. Durch die Anordnung der Transportstrecke oberhalb der Fachwand ist bei der Online-Maschine Rechtsversion unterhalb der Fachwand Raum für eine platzsparende Speicher- bzw. Verzögerungsstrecke, ausgeführt als Doppeltransportstrecke. Bei der Online-Maschine Linksversion ist die platzsparende Doppeltransportstrecke oberhalb der Fachwand angeordnet. Diese Transportstrecken werden in ihrer Summe als Spei¬ cherstrecken zur Realisierung der Online-Erkennungszeiten genutzt.In order to achieve a uniform, advantageous stacking direction in the compartment wall, with a uniform orientation in the separating device, e.g. B. letter side with address and postage stamp up, a transport route 14 is necessary in the legal versions. Due to the arrangement of the transport route above the compartment wall, the online version of the right-hand version below the compartment wall has space for a space-saving storage or delay route, designed as a double transport route. In the left-hand version of the online machine, the space-saving double transport path is arranged above the compartment wall. The sum of these transport routes is used as storage routes for realizing the online recognition times.
