Abstract

The products are supplied by a loader to a conveyor . Above the conveyor (1) is a guide assembly (12) formed from several guide members (15) fixed on an endless draw member (13) to run in the same direction as the conveyor direction parallel to the inlet openings (5) of the transport containers (3) and passing through the flight path of the products (6). The guide members are formed converging funnel-shaped in the direction of movement of the products. The guide members can be fixed on the draw member at the regular spacing of the transport containers and are driven on the same beat with the transport containers.

Description

Die Erfindung betrifft eine Einrichtung für den Transport von flachen Produkten, wie Versandtaschen, Pakete, Druckereiprodukte oder Werkstücke, die jeweils durch einen Beschicker den an einem angetriebenen Zugmittel einer Fördervorrichtung befestigten, eine dem darüber angeordneten Beschicker zugewendete Eintrittsöffnung aufweisenden Transportbehältern zugeführt werden.The invention relates to a device for the transport of flat products, such as mailing bags, parcels, printed products or workpieces, each of which is fed by a feeder to an inlet opening arranged above the feeder and which is attached to a driven traction means of a conveying device.

Solche Einrichtungen werden auch als Verteilförderer bei der Post oder bei Warenlagern verwendet, wo die einer Sammelstelle zufliessenden Produkte auf entfernt liegende Stellen zu verteilen sind.
Dabei weisen diese flachen Produkte nicht zuletzt aufgrund ihres unterschiedlichen Inhalts u.a. ungleichmässige äussere Formen und Steifigkeiten auf, die hohe Anforderungen an eine maschinelle Verarbeitung stellen.Such devices are also used as distribution conveyors at the post office or at warehouses, where the products flowing to a collection point are to be distributed to remote locations.
Not least because of their different contents, these flat products have, among other things, uneven external shapes and rigidity, which place high demands on machine processing.

Einrichtungen der Eingangs beschriebenen Art werden beispielsweise in Postämtern zum Sortieren von Versandtaschen nach ihren Versandadressen eingesetzt.
Hierzu werden die Versandtaschen nach Erfassen der Versandadresse einem Beschicker zugeführt, der die Versandtaschen den Transportbehältern übergibt, welche einer bestimmten Abgabestelle gesteuert zugeordnet sind.Devices of the type described at the beginning are, for example used in post offices to sort mailers according to their mailing addresses.
For this purpose, the mailing bags are fed to a feeder after recording the shipping address, which hands the mailing bags over to the transport containers, which are assigned to a specific delivery point in a controlled manner.

Die EP - A - 0 638 501 offenbart eine gattungsgleiche Einrichtung für den Weitertransport von einzeln zugeführten flachen Produkten, bei der die Transportbehälter eine nach oben gerichtete Eintrittsöffnung für die von einem Beschicker geförderten Produkte aufweisen.EP-A-0 638 501 discloses a device of the same type for the further transport of individually supplied flat products, in which the transport containers have an upward entry opening for the products conveyed by a feeder.

Die Praxis hat gezeigt, dass durch seitliche Öffnungen der Transportbehälter und den führungslosen Zwischenraum oberhalb der Transportbehälter eine zuverlässige Beschickung nicht gewährleistbar ist, wobei die unterschiedlichen Eigenschaften der geförderten Produkte und die relativ hohe Fördergeschwindigkeit sich weiter negativ auf die Zuverlässigkeit solcher Einrichtungen auswirken.Practice has shown that reliable loading cannot be guaranteed through lateral openings in the transport containers and the guide-free space above the transport containers, the different properties of the conveyed products and the relatively high conveying speed having a further negative effect on the reliability of such devices.

Aufgabe der Erfindung ist es deshalb, eine Einrichtung der eingangs genannten Art zu schaffen, mit welcher die Produkte auf dem Beschickungsweg die Transportbehälter lagerichtig erreichen.The object of the invention is therefore to provide a device of the type mentioned at the beginning with which the products reach the transport containers in the correct position on the loading path.

Erfindungsgemäss wird diese Aufgabe dadurch gelöst, dass oberhalb der Fördervorrichtung eine gleichsinnig zur Förderrichtung und etwa parallel zu den Eintrittsöffnungen der Transportbehälter verlaufende, die Flugbahn der Produkte durchsetzende, aus mehreren an einem endlos umlaufenden Zugorgan befestigten Führungsorganen gebildete Führungsanordnung vorgesehen ist.According to the invention, this object is achieved in that above the conveying device there is provided a guiding arrangement formed in the same direction as the conveying direction and approximately parallel to the inlet openings of the transport containers, penetrating the trajectory of the products and consisting of a plurality of guiding members attached to an endlessly rotating traction member is.

Durch diese konstruktive Massnahme wird es möglich sein, eine hohe Förderleistung zu erzielen.This constructive measure will make it possible to achieve a high delivery rate.

Vorteilhaft ist es, wenn die Führungsorgane sich in Bewegungsrichtung der Produkte trichterartig verengend ausgebildet sind, sodass durch die anfänglich weite Führung die Produkte die Führungsorgane sicher erreichen und auf dem anschliessenden Weg auf eine schmale Flugbahn versetzt werden können.It is advantageous if the guide members are designed in a funnel-like manner in the direction of movement of the products, so that the initially wide guide means that the products reach the guide members safely and can be set to a narrow trajectory on the subsequent path.

Zweckmässig erweist es sich, wenn die Führungsorgane nach den regelmässigen Abständen der sich folgenden Transportbehälter an dem Zugorgan befestigt und taktgleich mit den Transportbehältern angetrieben sind, wodurch keine spezielle Abstimmung zur Übereinstimmung der Führungsorgane und Transportbehälter an der Übergabestelle erforderlich wird.It is expedient if the guide members are fastened to the traction member after the regular intervals of the following transport containers and are driven in synchronism with the transport containers, as a result of which no special coordination is required to match the guide members and transport containers at the transfer point.

Unterschiedliche Abstände verlangen differenzierte Geschwindigkeiten und eine Abstimmung der Führungsorgane und Transportbehälter an der Übergabestelle.Different distances require different speeds and coordination of the management bodies and transport containers at the transfer point.

Durch eine zur Förderrichtung der Fördervorrichtung entgegengesetzt geneigte Lage der Transportbehälter, kann die Übergabestrecke an der Übergabestelle optimiert bzw. verlängert werden.The transfer path at the transfer point can be optimized or lengthened by an opposite inclination of the transport containers to the conveying direction of the conveying device.

Vorzugsweise ist das Zugmittel, an dem die Transportbehälter befestigt sind, durch seitlich beabstandete Förderketten gebildet, die um Umlenkrollen endlos umlaufen.The traction means, to which the transport containers are fastened, is preferably formed by laterally spaced conveyor chains, which run endlessly around deflection rollers.

Transportketten eignen sich besonders zur Befestigung der Führungsorgane durch ihre Seitenwände an den Laufachsen der Kettenglieder.Transport chains are particularly suitable for fastening the guide elements through their side walls on the running axes of the chain links.

Eine weitere Verbesserung der Betriebssicherheit und eine Vereinfachung gegenüber den bekannten Transportbehältern kann dadurch erzielt werden, indem die Transportbehälter allseits geschlossen ausgebildet sind und an der Eintrittsöffnung einen klappen- oder schieberartigen Deckel aufweisen.A further improvement in operational safety and a simplification compared to the known transport containers can be achieved in that the transport containers are closed on all sides and have a flap or slide-like cover at the inlet opening.

Zur Sicherstellung eines weitgehend stufenlosen Übergangs zwischen Führungsorganen und Transportbehältern im Übergabebereich ist es günstig, wenn das stromabwärts liegende Ende der Rutsche während der Beschickung an der in Förderrichtung rückwärtigen Innenwand des Transportbehälters wenigstens annähernd ansteht.To ensure a largely stepless transition between guide members and transport containers in the transfer area, it is advantageous if the downstream end of the chute at least approximately abuts the inner wall of the transport container rearward in the conveying direction.

Zur Verbesserung der Stabilisierung der Führungsorgane im Übergabebereich der Produkte kann eine über diesem Bereich sich erstreckende seitliche Transportkettenführung vorgesehen sein.To improve the stabilization of the guide members in the transfer area of the products, a lateral transport chain guide extending over this area can be provided.

Fig. 1 zeigt eine Fördervorrichtung 1, die an einem aus endlos umlaufenden Förderketten 2 gebildeten Zugmittel befestigte Transportbehälter 3 aufweist. Diese ist an ihrem, einem Beschicker 4 zugewendeten oberen Ende mit einer Eintrittsöffnung 5 versehen, durch die ein flaches Produkt 6 aus dem Beschicker 4 in den Transportbehälter 3 gefördert wird bzw. fällt. Bei den Produkten 6 handelt es sich um Versandtaschen, Pakete, Druckereiprodukte oder Werkstücke, die von einer Sammelstelle an verschiedene, entfernt liegende Orte, Lager- oder Arbeitsplätze verteilt oder zu anderen Sammelstellen transportiert werden. Die Transportbehälter 3, die in regelmässigen Abständen an dem Zugmittel befestigt sind, weisen eine entgegen der Förderrichtung F der Fördervorrichtung 1 (nach hinten) geneigte Lage auf, damit trotz der gedrängten Anordnungsweise die Länge der Beschickungsstrecke eines Transportbehälters in Förderrichtung F optimiert werden kann.
Ein vorgeschlagener Beschicker 4, der die ankommenden Produkte 6 im Takt der Fördervorrichtung 1 an diese weitergibt, besteht aus einem in flächigem Reibschluss an der einen Hauptfläche der Produkte 6 angreifenden Linearförderer 7 zum Übergeben der Produkte 6 an die Transportbehälter 3 und einem um eine senkrecht zur Förderrichtung des Linearförderers 7 gerichtete Achse angetriebenen Förderrotor 8, der sich beim Übergeben mit einem Abrollbereich seiner Umfangsfläche reibschlüssig auf der anderen Hauptfläche eines Produktes 6 abrollt. Der Antrieb des Beschickers 4 erfolgt durch einen Motor 9, der durch ein Getriebe 10 mit einem als Linearförderer 7 ausgebildeteten Förderband und dem Förderrotor 8 verbunden ist. Eine Vorspanneinrichtung 11 sorgt für den richtigen Anpressdruck des Förderrotors 8 an dem Produkte 6 (nachzulesen in der CH-Patentanmeldung Nr. 2501/95).
Zur Meidung eines führungslosen Förderweges zwischen dem Beschicker 4 und der Fördervorrichtung 1 resp. einem Transportbehälter 3 sieht die vorliegende Einrichtung eine Führungsanordnung 12 vor, die den Förderweg der Produkte 6 seitlich begrenzt. Diese Führungsanordnung 12 besteht aus einem oberhalb der Transportbehälter 3 gleichsinnig zur Förderrichtung F der Fördervorrichtung umlaufend angetriebenen Zugorgan 13, gebildet aus zwei parallelen Transportketten 14, an denen im Abstand der an dem Zugmittel der Fördervorrichtung 1 befestigten Transportbehälter 3 einzelne Führungsorgane 15 angeordnet sind, die die Flugbahn resp. den Förderweg eines Produktes 6 durchsetzen. Förderketten 2 und Transportketten 14 weisen jeweils parallele Trumme auf, die in einem Abschnitt eine Übergabestrecke bilden. Da die Abstände der Transportbehälter 3 und der Führungsorgane 15 an der Transportkette 14 gleich gross sind, bewegen sie sich mit gleicher Geschwindigkeit bzw. gemeinsam. Die Führungsorgane 15 sind trichterförmig ausgebildet und nach der Flugbahn eines Produktes 6 ausgerichtet, d.h. die Zutrittsöffnung 16 weist gegenüber der Eintrittsöffnung 5 der Transportbehälter 3 in Förderrichtung F betrachtet eine Erweiterung auf, die das Erfassen der Produkte 6 erleichtert und durch die anschliessende Verjüngung die Flugbahn eines Produktes 6 präzisiert.
Im vorliegenden Fall, wo die Eintrittsöffnung 5 der Transportbehälter 3 mit einem klappenartigen Deckel 17 versehen sind, der im offenen Zustand einen Führungsanteil bildet, ist das Führungsorgan 15 am stromabwärts gerichteten Ende mit einer als Rutsche ausgebildeten Leitfläche 18 versehen. Die teilweise aufgelöste Trichterform des Führungsorgans 15 wird aufgrund der Deckelöffnung in diesem Bereich durch den Deckel 17 annähernd wiederhergestellt.
Ein Schiebedeckel würde diese Vorkehrungen umgehbar machen. Die Lage der Leitfläche 18 ist an dem Führungsorgan 15 so gewählt, dass das stromabwärts liegende Ende der Rutsche während der Beschickung an der in Förderrichtung F rückwärtigen Innenwand 19 des Transportbehälters 3 etwa ansteht, jedenfalls keinen störenden Absatz bildet oder die Eintrittsöffnung 5 des Transportbehälters 3 nachteilig verkleinert.1 shows a conveyor device 1 which has transport containers 3 fastened to a traction means formed from endlessly rotating conveyor chains 2. This is provided at its upper end facing a feeder 4 with an inlet opening 5 through which a flat product 6 is conveyed or falls from the feeder 4 into the transport container 3. The products 6 are mailing bags, parcels, printed products or workpieces that are distributed from one collection point to different, distant locations, storage or work places, or transported to other collection points. The transport containers 3, which are attached to the traction means at regular intervals, have an inclined position counter to the conveying direction F of the conveying device 1 (to the rear), so that the length of the loading path of a transport container in the conveying direction F can be optimized despite the compact arrangement.
There is a proposed feeder 4, which passes the incoming products 6 to the conveyor device 1 in time with the latter of a linear conveyor 7 engaging in a flat frictional engagement on the one main surface of the products 6 for transferring the products 6 to the transport containers 3 and a conveyor rotor 8 driven about an axis perpendicular to the conveying direction of the linear conveyor 7, which rotatably engages with a rolling area of its peripheral surface during transfer rolls on the other main surface of a product 6. The feeder 4 is driven by a motor 9, which is connected by a gear 10 to a conveyor belt designed as a linear conveyor 7 and the conveyor rotor 8. A pretensioning device 11 ensures the correct contact pressure of the conveyor rotor 8 on the product 6 (to be read in the CH patent application No. 2501/95).
To avoid a guide-free conveying path between the feeder 4 and the conveying device 1, respectively. a transport container 3, the present device provides a guide arrangement 12 which laterally limits the conveying path of the products 6. This guide arrangement 12 consists of a pulling member 13 which is driven above the transport container 3 in the same direction as the direction of conveyance F of the conveying device, formed from two parallel transport chains 14, on which individual guide members 15 are arranged at a distance from the transport containers 3 fastened to the traction means of the conveying device 1, which guide the Trajectory resp. enforce the conveyance route of a product 6. Conveyor chains 2 and transport chains 14 each have parallel runs which form a transfer section in one section. Since the distances between the transport containers 3 and the guide members 15 on the transport chain 14 are the same, they move at the same speed or together. The guide members 15 are funnel-shaped and aligned with the trajectory of a product 6, ie the access opening 16 has an extension, viewed in the direction of conveyance F, opposite the inlet opening 5 of the transport container 3, which facilitates the grasping of the products 6 and, through the subsequent tapering, makes the trajectory of a product 6 more precise.
In the present case, where the inlet opening 5 of the transport container 3 is provided with a flap-like cover 17, which forms a guide portion in the open state, the guide member 15 is provided at the downstream end with a guide surface 18 designed as a slide. The partially dissolved funnel shape of the guide member 15 is approximately restored due to the lid opening in this area through the lid 17.
A sliding cover would make these arrangements avoidable. The position of the guide surface 18 on the guide member 15 is selected such that the downstream end of the chute is in contact with the inner wall 19 of the transport container 3 rearward in the conveying direction F, in any case does not form a disruptive step or the inlet opening 5 of the transport container 3 is disadvantageous downsized.

Es ist jeweils durch eine Verbindungsstange 20 in der einen Schwenkachse 21 und in der anderen Schwenkachse 22 eines Kettengliedes 23 befestigt, so dass die Transportketten 14 keine Einschränkung bezüglich Beweglichkeit ihrer Kettenglieder erfahren. Zur Verstärkung der Verbindung mit der Transportkette 14 ist jeweils eine an den Seitenwänden 24 des Führungsorgans 15 befestigte Leiste 25 vorgesehen.2 to 4 indicate the formation of a guide member 15 and its attachment to the pulling member 13 formed from the two transport chains 14.
Fig. 2 shows the funnel-shaped guide member 15 in the loading position. It is fastened in each case by a connecting rod 20 in one pivot axis 21 and in the other pivot axis 22 of a chain link 23, so that the transport chains 14 are not restricted in terms of the mobility of their chain links. To strengthen the connection to the transport chain 14, a bar 25 is provided on the side walls 24 of the guide member 15.

Die Fig. 5 bis 7 veranschaulichen die Ausbildung eines Transportbehälters 3 in der Entleerungslage. Fig. 5 zeigt den noch geschlossenen Transportbehälter 3 der seine Lage gegenüber der Beschickungsposition um etwa 180° geändert hat. Das Produkt 6 befindet sich jetzt in Deckelnähe und verlässt den Transportbehälter 3 sobald der Deckel 17 geöffnet wird (siehe Fig. 6). In geschlossenem Zustand des Transportbehälters 3 wird der Deckel 17 durch eine Verriegelungsvorrichtung 26 festgehalten, deren Riegel 27 zur richtigen Zeit durch eine Entriegelungsvorrichtung 28 gemäss Fig. 7 aus der Arretierung gehoben wird. Das Schwenken des Deckels 17 zum Öffnen eines Transportbehälters 3 erfolgt durch eine Drehfeder (nicht gezeichnet). Gegen die Kraft der Drehfeder wird der Deckel 17 wieder geschlossen.5 to 7 illustrate the formation of a transport container 3 in the emptying position. 5 shows the still closed transport container 3, which has changed its position by approximately 180 ° with respect to the loading position. The product 6 is now near the lid and leaves the transport container 3 as soon as the lid 17 is opened (see FIG. 6). In the closed state of the transport container 3, the cover 17 is held in place by a locking device 26, the bolt 27 of which is lifted out of the lock at the right time by an unlocking device 28 according to FIG. 7. The pivoting of the lid 17 to open a transport container 3 is carried out by a torsion spring (not shown). The cover 17 is closed again against the force of the torsion spring.
