Description

Die Erfindung betrifft einen kastenförmigen Behälter für flache Sendungen in stehender Position mit einer aus dem oben offenen Behälter entfernbaren Stapelstütze sowie mit einem Boden, zwei schmalen Stirnseitenwänden und zwei seitlichen Längswänden. Die Sendungen sind im Behälter mit ihren großflächigen Seiten zu den Stirnseitenwänden hin ausgerichtet.The invention relates to a box-shaped container for flat items in a standing position with a removable from the open-topped container stacking support and with a bottom, two narrow end walls and two lateral longitudinal walls. The broadcasts are aligned in the container with their large-scale sides to the end walls.

Moderne Briefsortieranlagen erreichen Spitzendurchsätze bis ca. 45.000 Sendungen pro Stunde. Die Entleerung erfolgt in der Regel manuell, d.h. die sortierten Sendungsstapel werden von Hand aus dem Sortierer in Postbehälter umgeladen. Die Postbehälter selbst werden danach entweder manuell auf Förderwagen gestapelt oder modernen Tray Management System übergeben. Dieser manuelle Prozess ist mit einer hohen Fehlerrate des Operateurs, einer hohen monotonen Belastung des Operateurs und sehr geringen Durchsätzen verbunden.
Bei der Zuführung der Sendungen in den Sortierer erfolgt in der Regel ebenfalls eine manuelle Übergabe aus Behältern auf die Vereinzelungsvorrichtung des Sortierers.
Eine weitere Leistungssteigerung würde daher zusätzlich Bedienpersonal erfordern und damit die Rentabilität der Sortieranlage senken.Modern letter sorting systems achieve peak throughputs of up to 45,000 shipments per hour. The emptying is usually done manually, ie the sorted consignment stacks are manually reloaded from the sorter in postal container. The post containers themselves are then either manually stacked on trolleys or handed over to the modern tray management system. This manual process is associated with a high error rate of the surgeon, a high monotonous load of the surgeon and very low throughputs.
When feeding the mail items to the sorter, manual transfer from containers to the sorting device of the sorter is also generally carried out.
A further increase in performance would therefore require additional operators and thus reduce the profitability of the sorting system.

In EP 0 109 325, FR 2 621 297 werden hierfür benötigte Postbehälter beschrieben. Diese bestehen aus Kunststoff (PP) und weisen diverse Versteifungen auf, um eine benötigte Formstabilität zu erreichen. Diese Behälter sind so gestaltet, dass sie bei gleicher gegenseitiger Ausrichtung aufeinander und bei zueinander um 180° um die vertikale Achse verdrehter Ausrichtung ineinander stapelbar sind.
In diesem Zusammenhang wurde ein Behälter, geeignet für flache Sendungen in stehender Position, bekannt (DE 89 13 760 U1), dessen Innenseiten der seitlichen Längswände in regelmäßige Abständen senkrecht zum Boden und gerade verlaufende, langgestreckte, oben offene Ausnehmungen für eine entfernbare Stapelstütze aufweisen, die in der Längsrichtung der seitlichen Längswände breiter als ihre schlitzförmigen Öffnungen zum Behälterinnenraum sind. Die Stapelstütze besitzt an ihren beiden seitlichen Enden Formelemente, die in den langgestreckten Ausnehmungen durch die schlitzförmigen Öffnungen hindurch mit einer formschlüssigen Verbindung nur senkrecht zum Boden verschiebbar sind. Diese Ausnehmungen sind in der Längsrichtung der seitlichen Längswände breiter als ihre schlitzförmigen Öffnungen. In der US 3 200 983 sind die Ausnehmungen als Schwalbenschwanzführungen ausgeführt.EP 0 109 325, FR 2 621 297 describe postal containers required for this purpose. These are made of plastic (PP) and have various stiffeners to achieve a required dimensional stability. These containers are designed so that they can be stacked on each other with the same mutual alignment and with each other rotated by 180 ° about the vertical axis orientation.
In this context, a container, suitable for flat broadcasts in a standing position, known (DE 89 13 760 U1), the insides of the lateral longitudinal walls in regular Perpendicular to the ground and straight, elongated, open-topped recesses for a removable stack support, which are wider in the longitudinal direction of the lateral longitudinal walls than their slot-shaped openings to the container interior. The stack support has at its two lateral ends form elements which are displaceable in the elongated recesses through the slot-shaped openings with a positive connection only perpendicular to the ground. These recesses are wider in the longitudinal direction of the lateral longitudinal walls than their slot-shaped openings. In US 3 200 983, the recesses are designed as dovetail guides.

Für weitere Durchsatzerhöhungen ist die Entwicklung automatischer Befüllung- und Entleerungsautomaten und der hierzu geeigneten Posttransportbehälter erforderlich.For further throughput increases, the development of automatic filling and emptying machines and the appropriate postal transport container is required.

Hierzu wurde das sogenannte Mail Cartridge System (MCS) bekannt (US 6 026 967, WO 97/36523), bei dem ein spezieller Behälter Verwendung findet, der als Stapelfach selbst ausgebildet direkt am Sortierer vor dem Einstapelmechanismus aufgehängt wird. Die Sortierung erfolgt ohne Umladeprozess direkt in den kassettenförmigen Behälter. Nach Abschluss des Sortierprozesses wird die Kassette von einem Roboter am Sortierer ausgehängt, durch eine leere Kassette ersetzt und einem Puffer- oder Transportsystem übergeben. Die systemimmanenten Nachteile des MCS Systems sind zum einen die aufgrund der hohen Funktionsintegration komplexe und schwere Kassette, die deutlich erhöhten Transportkosten, die nicht vorhandene Stapel- und Schachtelbarkeit, eingeschränkte Luftfrachtfähigkeit, und zum anderen die geringen Füllraten der Behälter. Diese können nicht nachträglich mit Postgütern aufgefüllt werden.For this purpose, the so-called mail cartridge system (MCS) was known (US 6,026,967, WO 97/36523), in which a special container is used, which is designed as a stacking tray itself is suspended directly on the sorter before the stacking mechanism. The sorting takes place without reloading process directly into the cassette-shaped container. Upon completion of the sorting process, the cassette is unmounted by a robot at the sorter, replaced with an empty cassette, and transferred to a buffering or transporting system. The system-inherent disadvantages of the MCS system are, on the one hand, the complex and heavy cassette due to the high degree of functional integration, the significantly increased transport costs, the lack of stackability and nestability, limited air freight capacity and, second, the low filling rates of the containers. These can not be refilled with postage.

Der Erfindung liegt die Aufgabe zugrunde, einen kastenförmigen Behälter mit einer entfernbaren Stapelstütze zur Aufnahme und zum Transport flacher Sendungen zu schaffen, bei dem trotz Seitenwänden mit geringer Steifigkeit ein sicherer Halt der den Stapeldruck aufnehmenden Stapelstütze in verschiedenen Stellungen entsprechend der Stapelgröße gewährleistet ist und der ein unkontrolliertes Verrutschen der Sendungen senkrecht zur Stapelrichtung verhindert.The invention has for its object to provide a box-shaped container with a removable stack support for receiving and transporting flat broadcasts, in which despite side walls with low rigidity a secure hold of the pile pressure receiving stack support is guaranteed in different positions according to the stack size and prevents uncontrolled slipping of the programs perpendicular to the stacking direction.

Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruches 1 gelöst.According to the invention the object is achieved by the features of claim 1.

Die Innenseiten der seitlichen Längswände der Behälter weisen in regelmäßigen Abständen senkrecht zum Boden und gerade verlaufende, langgestreckte, oben offene Ausnehmungen auf, die in der Längsrichtung der seitlichen Längswände breiter als ihre schlitzförmigen Öffnungen zum Behälterinnenraum sind.
An ihren beiden seitlichen Enden besitzt die Stapelstütze Formelemente, die in den langgestreckten Ausnehmungen durch die schlitzförmigen Öffnungen hindurch mit einer formschlüssigen Verbindung nur senkrecht zum Boden verschiebbar sind. Die Stapelstütze wird also in zwei gegenüberliegende Ausnehmungen mit ihren Formelementen von oben eingeführt und nach unten bis zum Boden geschoben. Dabei werden die Ausnehmungen so gewählt, dass der jeweilige Stapel oder Teilstapel unter einem bestimmten Stapeldruck gehalten wird.
Im Behälterboden befinden sich Längsrippen. Auf den Längsrippen können die Sendungen in Behälterlängsrichtung leicht verschoben werden, was beim Zusammenfügen von zwei Teilstapeln oder zum Herstellen eines bestimmten Stapeldruckes notwendig ist. Da im Behälter Sendungen unterschiedlicher Formate transportiert werden, ist ein Verrutschen der kleineren Sendungen während des Transportes senkrecht zur Stapelrichtung zu vermeiden, damit das notwendige Stapelbild für eine Weiterverarbeitung erhalten bleibt. Dies wird erreicht, indem die Höhen der Längsrippen von den seitlichen Längswänden zur Mitte des Behälters hin abnehmen. Dadurch kippen die Sendungen über die der Behälterseitenwand nächste Längsrippe zur Mitte hin und bleiben mit ihren Vorderkanten an der nächsten Längsrippe hängen, wodurch eine Verschiebung verhindert wird.The inner sides of the lateral longitudinal walls of the containers have at regular intervals perpendicular to the ground and straight, elongated, open-topped recesses which are wider in the longitudinal direction of the lateral longitudinal walls than their slot-shaped openings to the container interior.
At its two lateral ends, the stack support has form elements which are displaceable in the elongate recesses through the slot-shaped openings with a positive connection only perpendicular to the ground. The stack support is thus inserted into two opposite recesses with their form elements from above and pushed down to the ground. The recesses are chosen so that the respective stack or partial stack is kept under a certain stack pressure.
In the container bottom there are longitudinal ribs. On the longitudinal ribs, the programs can be easily moved in the container longitudinal direction, which is necessary when assembling two part stacks or for producing a certain stacking pressure. Since shipments of different formats are transported in the container, slippage of the smaller items during transport perpendicular to the stacking direction is to be avoided, so that the necessary stack pattern is maintained for further processing. This is achieved by removing the heights of the longitudinal ribs from the lateral longitudinal walls towards the center of the container. As a result, the consignments tilt over the container longitudinal side of the next longitudinal rib towards the center and remain with their leading edges to the next longitudinal rib hanging, whereby a shift is prevented.

Im Boden des Behälters befinden sich durch die Längsrippen in Teilquerrippen unterteilte Querrippen im Abstand der Ausnehmungen. An den Teilquerrippen stützt sich die vollständig in den Behälter eingeschobene Stapelstütze mit Aussparungen für die Längsrippen zusätzlich zur seitlichen Führung in den Ausnehmungen gegen den Stapeldruck ab, wodurch die auf die Stapelstütze wirkende Biegebeanspruchung reduziert wird.In the bottom of the container are divided by the longitudinal ribs in partial transverse ribs divided transverse ribs at a distance from the recesses. At the partial transverse ribs, the stack support, which is completely inserted into the container, is supported by recesses for the longitudinal ribs in addition to the lateral guidance in the recesses against the stack pressure, whereby the bending load acting on the stack support is reduced.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen dargelegt.Advantageous embodiments of the invention are set forth in the subclaims.

Damit eine aus Kunststoff (PP) bestehende Stapelstütze eine notwendige Steifigkeit aufweist und die Fertigungskosten gering gehalten werden, ist es vorteilhaft, diese doppelwandig auszuführen und an jeder Seite zwei Formelemente im Abstand der Ausnehmungen der Behälterwand voneinander, die an ihren Enden voneinander weg abgekröpft sind, vorzusehen.For a plastic (PP) existing stacking support has a necessary rigidity and the manufacturing costs are kept low, it is advantageous to perform this double-walled and on each side two form elements at a distance from each other the recesses of the container wall, which are bent away from each other at their ends, provided.

Die Teilquerrippen weisen vorteilhaft sägezahnförmiges Profil auf, deren Zahnspitzen durch die oberen Ränder der Längsrippen gebildet werden. Die steilen Zahnflanken sind zu den Längswänden des Behälters hin gerichtet.The partial transverse ribs advantageously have a sawtooth-shaped profile whose tooth tips are formed by the upper edges of the longitudinal ribs. The steep tooth flanks are directed towards the longitudinal walls of the container.

Wird der Behälter so ausgeführt, dass mehrere Behälter bei gleicher Ausrichtung aufeinander stapelbar und bei um 180° um die Vertikalachse verdrehter gegenseitiger Ausrichtung teilweise ineinander stapelbar sind, so ist die Stapelstütze vorteilhaft nur so hoch ausgeführt, dass sie beim Ineinanderstapeln den Boden des jeweils oberen Behälters nicht berührt. Dadurch kann die Stapelstütze in sicherer unverlierbarer Position verbleiben.If the container is designed in such a way that several containers can be stacked on one another and rotated at 180 ° about the vertical axis, the stack support is advantageously only designed so high that when stacked one inside the other, the bottom of the respective upper container not touched. This allows the stack support to remain in a safe captive position.

Um einen automatischen Be- und Entladeablauf zu ermöglichen, besitzt die Stapelstütze vorteilhaft zwei zentrierbare Greiferaufnahmen zum maschinellen Handhaben.In order to enable an automatic loading and unloading process, the stack support advantageously has two centerable gripper receptacles for machine handling.

Anschließend wird die Erfindung in einem Ausführungsbeispiel anhand der Zeichnungen näher erläutert.Subsequently, the invention will be explained in an embodiment with reference to the drawings.

In FIG 1 ist ein erfindungsgemäßer Behälter ohne eine eingeschobene Stapelstütze dargestellt. Er besitzt zwei Stirnseitenwände 1, zwei seitliche Längswände 2 mit senkrecht zum Boden 6 und gerade verlaufenden, langgestreckten, oben offenen Ausnehmungen 3 an den Innenseiten. Die Seitenwände 1,2 besitzen keine Versteifungen und sind im oberen Teil etwas nach außen versetzt, um ein Ineinanderstapeln zu ermöglichen. In den Stirnseitenwänden befinden sich zwei Griffe 4 für den Handtransport und Stapelmittel 5, die so angeordnet und ausgeführt sind, dass bei gleicher Orientierung die Behälter aufeinander stehen (der obere Behälter taucht nicht in den unteren Behälter ein) und bei um 180° um die Vertikalachse verdrehter gegenseitiger Ausrichtung die Behälter gemäß der Höhe des nach außen versetzten Teils der Seitenwände 1,2 der jeweils obere Behälter in den unteren Behälter eintaucht. Wie zu erkennen, stehen die Sendungen 9 parallel zu den Stirnseitenwänden 1. Im Boden 6 befinden sich parallel zu den seitlichen Längswänden 2 verlaufende Längsrippen 7.
Die Höhe der Längsrippen 7 nimmt von den Längswänden 2 zur Mitte hin ab. Dadurch kippen die Sendungen 9 nach innen ab und jede Sendung 9 bleibt an der jeweils nächsten Längsrippe 7 hängen, da die Längsrippen 7 über der Behältermitte hinaus wieder höher werden.
In FIG 2 ist dieser Vorgang besonders gut zu erkennen. Zwischen den Längsrippen 7 befinden sich im Abstand der Ausnehmungen 3 Teilquerrippen 8, die ein sägezahnförmiges Profil besitzen, deren Zahnspitzen durch den oberen Rand der Längsrippen 7 gebildet werden. Die steilen Zahnflanken sind zu der Längswand 2 gerichtet, zu der hin die Sendungen 9 zu orientieren sind, d.h. zu der rechten Längswand 2.
Die Ausbildung der Stapelstütze 10 ist der FIG 3 zu entnehmen. Wie zu erkennen, ist sie doppelwandig ausgeführt, um die Biegesteifigkeit zu erhöhen. Zur weiteren Steifigkeitserhöhung befinden sich auf den Längsflächen Rippen 14. Die Stapelstütze 10 ist oben und unten gleich ausgeführt, so dass bei einem automatischen Ablauf des Be- und Entladens des Behälters die Orientierung der Stapelstütze 10 nicht beachtet werden muss. Damit die Stapelstütze 10 bis zum Boden 6 des Behälters eingeschoben werden kann, weisen die oberen und unteren Seiten Aussparungen 11 für die Längsrippen 7 auf. Weiterhin befinden sich auf beiden Seiten zentrierbare Greiferaufnahmen 12 zum maschinellen Handhaben. An den seitlichen Enden besitzt die Stapelstütze 10 an jeder Seite zwei Formelemente 13 in Verlängerung der beiden Wände und im Abstand der Ausnehmungen 3 der Behälterwand voneinander, die an ihren Enden voneinander weg abgekröpft sind. Die beiden Formelemente 13 auf jeder Seite werden also in benachbarten Ausnehmungen 3 geführt.
Dies ist besonders gut in FIG 4 dargestellt. Jede oben offene Ausnehmung 3 besitzt einen rechteckigen Querschnitt, wobei sich im zum Behälterinneren gerichteten Abschluss ein senkrecht zum Boden gerichteter Spalt befindet. Sehr gut sind auch die parallel zu den seitlichen Längswänden 2 verlaufenden Längsrippen 7 und die Teilquerrippen 8 erkennbar, welche bündig mit der zum Betrachter gerichteten Spaltkante angeordnet sind.In FIG 1, an inventive container is shown without an inserted stack support. He has two end walls 1, two lateral longitudinal walls 2 with perpendicular to the bottom 6 and straight, elongated, open-topped recesses 3 on the insides. The side walls 1,2 have no stiffeners and are slightly offset in the upper part to the outside to allow nesting. In the end walls are two handles 4 for hand transport and stacking means 5, which are arranged and designed so that in the same orientation, the containers stand on each other (the upper container does not dip into the lower container) and at 180 ° about the vertical axis twisted mutual alignment, the container according to the height of the outwardly offset portion of the side walls 1,2 of the respective upper container in the lower container is immersed. As can be seen, the items 9 are parallel to the front side walls 1. In the bottom 6 are parallel to the lateral longitudinal walls 2 extending longitudinal ribs. 7
The height of the longitudinal ribs 7 decreases from the longitudinal walls 2 towards the center. As a result, the mailings 9 tilt inwards and each shipment 9 remains hanging on the respective next longitudinal rib 7, since the longitudinal ribs 7 are above the container center out again higher.
In Figure 2, this process is particularly easy to recognize. Between the longitudinal ribs 7 are located at a distance of the recesses 3 partial transverse ribs 8, which have a sawtooth-shaped profile, the tooth tips are formed by the upper edge of the longitudinal ribs 7. The steep tooth flanks are directed to the longitudinal wall 2, to which the consignments 9 are to be oriented, ie to the right longitudinal wall second
The design of the stack support 10 is shown in FIG 3. As can be seen, it is double-walled in order to increase the flexural rigidity. For further increase in rigidity, there are ribs 14 on the longitudinal surfaces. The stack support 10 has the same design at the top and bottom, so that the orientation of the stack support 10 does not have to be taken into account in an automatic process of loading and unloading the container. Thus, the stack support 10 can be inserted to the bottom 6 of the container, the upper and lower sides have recesses 11 for the longitudinal ribs 7. Furthermore, there are centerable gripper receptacles 12 for machine handling on both sides. At the lateral ends of the stack support 10 has on each side two mold elements 13 in extension of the two walls and at a distance from the recesses 3 of the container wall from each other, which are bent away from each other at their ends. The two form elements 13 on each side are thus guided in adjacent recesses 3.
This is particularly well illustrated in FIG. Each open-topped recess 3 has a rectangular cross-section, wherein in the direction of the container interior conclusion is directed perpendicular to the ground gap. The longitudinal ribs 7 extending parallel to the lateral longitudinal walls 2 and the partial transverse ribs 8, which are arranged flush with the gap edge directed towards the viewer, are also very well recognizable.

Da die Formelemente 13 eine Verlängerung der Wände der Stapelstütze 10 mit einer Abkröpfung darstellen, ist sichergestellt, dass die Stapelstütze 10 auch mit ihrem unteren Teil gegen den Stapeldruck ohne größeres Spiel geführt wird. Es ist von oben auch die prismenförmige Greiferaufnahme 12 erkennbar, die eine definierte Position des Greifers in der Stapelstütze 10 gewährleistet.Since the mold elements 13 represent an extension of the walls of the stack support 10 with a bend, it is ensured that the stack support 10 is guided with its lower part against the stack pressure without greater play. It can also be seen from above the prismatic gripper receptacle 12, which ensures a defined position of the gripper in the stack support 10.
