The container base, adjacent to the edges, has upwardly sloped faces (17) above the runners. The angle of the floor adjacent to the edges matches the upper slope of the runners.

Description

Die Erfindung betrifft einen einstückig aus Kunststoff hergestellten Transportkasten mit einem im mittleren Bereich des Kastens ebenen Boden, unter dem sich im Randbereich des Kastens mindestens zwei parallele Kufen befinden, die durch quer zu den Kufen verlaufende Rippen mit dem Boden verbunden sind, bei dem durch die Kufen, die Querrippen und die Bodenunterfläche nach außen und/oder innen hin offene Taschen gebildet sind, und bei dem die Kufen an der der Kastenmitte zugewandten Seite einen längsgerichteten Abschnitt aufweisen, der nach oben gerichtet ist.The invention relates to a one-piece plastic manufactured transport box with one in the middle Area of the box level floor, under which in the Edge area of the box at least two parallel runners located by ribs running across the runners are connected to the ground by which Skids, the cross ribs and the bottom surface behind pockets are formed on the outside and / or inside, and with the runners facing the middle of the box Side have a longitudinal section, which is directed upwards.

Diese Bauart eines Transportkastens ist aus der DE 39 09 022 C2 bekannt geworden. Sie zeichnet sich durch eine hohe Bodenstabilität, wie sie für hochbelastbare Transportkästen der Industrie gefordert wird, einen ebenen Boden sowie durch gute und geräuscharme Lauffähigkeit auf Röllchenbahnen aus. Bei diesem bekannten und bewährten Transportkasten sind vier Kufen unter dem Kastenboden neben den Kanten des Kastenbodens vorgesehen, die einen umlaufenden Rahmen bilden. Zwischen der Unterfläche des Bodens und der Oberfläche der Kufen einerseits und den einander zugewandten Seiten der Rippen andererseits sind unter dem Boden eine Vielzahl von Taschen gebildet, die nach außen offen und nach innen (der Kastenmitte zu) durch eine die Innenkante der Kufe mit dem Kastenboden verbindende Längsrippe geschlossen sind.This type of transport box is from DE 39 09 022 C2 became known. It stands out a high level of soil stability, such as that for heavy-duty Transport boxes the industry is called for flat floor and good and low-noise running on roller tracks. In this well-known and proven transport box are four runners under the Box bottom provided next to the edges of the box bottom, that form an all-round frame. Between the Bottom surface of the floor and the surface of the runners on the one hand and the mutually facing sides of the ribs on the other hand, there are a variety of under the floor Pockets formed that are open to the outside and inside (towards the middle of the box) through the inner edge of the runner longitudinal rib connecting the box bottom closed are.

Dieser Boden konnte, wie in der DE 40 06 188 C2 beschrieben, in seinem Laufverhalten auf Röllchenbahnen noch dadurch verbessert werden, daß die Kufen an ihrem der Kastenmitte zugewandten Rand einen schräg nach oben verlaufenden Abschnitt aufweisen. Der von den beiden Abschnitten eingeschlossene Winkel beträgt 160 ± 15 °, die Abweichung von der Ebene ist also nur gering. Diese Verbesserung des Laufverhaltens wurde insbesondere bei mittig schwer belasteten Transportkästen, deren Boden sich nach unten hin durchbiegt, wirksam. Unter der Durchbiegung des Boden durch die Last entstehen Deformationen auch im Bereich der Kufen, welche die beiden Abschnitte der Kufen wie zwei Schrägflächen erscheinen lassen, deren Berührungslinie am tiefsten liegt, so daß zwei mit ihrer Oberfläche nach unten gerichtete Rampen entstehen, wobei die einzelnen Röllchen zunächst auf die eine Rampe auflaufen und dann auf der anderen Rampe wieder ablaufen.
Ist dieser Kasten nicht so schwer beladen, deformieren sich die Kufen nicht in der beschriebenen Weise, wodurch die Geräuschentwicklung stärker ist, weil nur die nach innen gerichteten Kanten der Kufen mit ihren rampenartigen längsgerichteten Abschnitten sanft auf die Röllchen auflaufen, nicht aber die nach außen gerichteten Kanten der Kufen.
An der Außenseite der Kufen lassen sich bei einem Kasten mit ebenem Kastenboden aber keine nach oben geneigten längsgerichteten rampenartige Abschnitte herstellen, weil der Kasten sonst aus seiner Herstellungsform nicht herausnehmbar, also nicht entformbar ist.As described in DE 40 06 188 C2, this floor could still be improved in its running behavior on roller conveyors in that the runners have an obliquely upward section at their edge facing the center of the box. The angle enclosed by the two sections is 160 ± 15 °, so the deviation from the plane is only slight. This improvement in running behavior was particularly effective in the case of transport boxes which were heavily loaded in the middle and whose bottom bends downwards. Under the deflection of the floor by the load, deformations also occur in the area of the runners, which make the two sections of the runners appear like two inclined surfaces, the contact line of which is the deepest, so that two ramps are formed with their surface facing downwards, the individual rollers first run onto one ramp and then run down the other ramp.
If this box is not so heavily loaded, the runners do not deform as described, which increases the noise level, because only the inward edges of the runners with their ramp-like longitudinal sections gently run onto the rollers, but not the outward ones Edges of the runners.
On the outside of the runners, however, in the case of a box with a flat box bottom, no upwardly inclined longitudinal ramp-like sections can be produced, because otherwise the box cannot be removed from its production form, that is to say cannot be removed from the mold.

Um die unter dem Boden durch die Kufen und die sie tragenden Querrippen gebildeten Taschen besser reinigen zu können, ist bei der in der DE 41 05 527 C2 beschriebenen Ausführungsform des oben beschriebenen Kastens der DE 39 09 022 C2 einfach die Längsrippe weggelassen, so daß beidseitig offene Taschen entstanden sind. Dadurch ist die Reinigungsmöglichkeit vereinfacht, die Stabilität der Bodenausbildung jedoch verschlechtert.To the under the floor through the runners and the ones carrying them Bags made of cross ribs can be cleaned better can, is in that described in DE 41 05 527 C2 Embodiment of the box described above DE 39 09 022 C2 simply omitted the longitudinal rib, see above that open pockets were created on both sides. Thereby the cleaning option is simplified, the stability soil training deteriorated, however.

Alle diese erwähnten bekannten Transportkästen weisen einen ebenen Boden auf. Dieser ist bei der Verpackung quaderförmiger Ware vorteilhaft, weil auf den Boden gestellte Ware in Form gleichdimensionierter Quader eine ebene Oberfläche bildet, auf die man weitere Ware eben heraufstellen kann. Für die Verladung von Schüttgut aller Art, von Getreide, Futter u.a. bis zu Schrauben, Muttern und sonstigen Kleinteilen aus Metall ist ein ebener Boden nicht erforderlich, oft aus Gründen einer besseren Reinigung gar nicht einmal günstig, weil sich rechtwinklige Kastenecken schwerer als stumpfwinklige reinigen lassen.All of these known known transport boxes have on a flat floor. This is with the packaging cuboid goods advantageous because on the floor provided goods in the form of cuboids of equal dimensions forms a flat surface on which you can add more goods can just put up. For loading bulk goods of all kinds, from grain, feed etc. up to screws, Nuts and other small parts made of metal a level floor is not required, often for reasons a better cleaning is not even cheap because rectangular box corners are heavier than obtuse angles get cleaned.

Alle diese erwähnten bekannten Transportkästen haben eine rahmenförmige Anordnung von vier Kufen unter dem Boden. Die DE 41 05 527 zeigt aber auch eine Ausführungsform mit zwei parallel angeordneten Kufen.All of these known transport boxes have a frame-shaped arrangement of four runners under the Ground. DE 41 05 527 also shows an embodiment with two skids arranged in parallel.

Die Erfindung vermeidet die Nachteile des Standes der Technik. Es ist die Aufgabe der Erfindung, die Laufeigenschaften des Kastens auf Röllchenbahnen mit einfachen Mitteln zu verbessern und die Geräuschbildung beim Laufen eines solchen Kastens auf Röllchenbahnen weiter herabzusetzen.The invention avoids the disadvantages of the prior art Technology. It is the object of the invention, the running properties of the box on roller conveyors with simple Means improve and noise when running such a box on roller conveyors further decrease.

Die Erfindung besteht darin, daß die Kufen an ihrer Außenseite einen weiteren längsgerichteten Abschnitt aufweisen, der nach außen oben gerichtet ist, und daß der Boden des Kastens im Randbereich eine nach außen oben gerichtete geneigte Fläche aufweist, die oberhalb der Kufen befindlich ist, die die gleiche Neigung wie der nach außen gerichtete längsgerichtete Abschnitt der Kufe aufweist und die in die mittig angeordnete ebene Bodenfläche übergeht.The invention is that the runners on their Outside another longitudinal section have, which is directed upwards outwards, and that the bottom of the box in the edge area an outward directed has inclined surface above the runners which is the same inclination as that after exterior longitudinal section of the runner has and in the centrally arranged flat bottom surface transforms.

Dieser Transportkasten weist somit an beiden Längsseiten der Kufen schräg nach oben verlaufende rampenartige Abschnitte auf, so daß die Vorgänge sowohl des Anlaufens an die Röllchen als auch des Ablaufens von den Röllchen weich und ruhig erfolgen, wodurch die Lauffähigkeit des Kastens auf Röllchenbahnen optimiert und die Geräuschbildung optimal vermindert ist. Dabei ist das bisher bestehende Problem der Nichtentformbarkeit der äußeren Schrägfläche durch eine andere Gestaltung des Bodens gelöst, der zwar in der Mitte eben, im Randbereich oberhalb der Kufen jedoch leicht nach außen ansteigend geformt ist. Diese nicht ebenen, nach außen ansteigenden Teile des Bodens sind meist schmaler als der ebene Mittelteil des Bodens und weisen eine nur geringe Abweichung von der Ebene auf. Hängt der Boden unter aufgestellter Last in der Mitte durch, fällt diese Schrägstellung des Randbereiches des Bodens überhaupt nicht auf. Für den Transport von Schüttgut aller Art spielt diese Schrägstellung des Randbereiches des Bodens überhaupt keine Rolle, für den Transport von quaderförmiger Ware nur eine geringfügige.This transport box thus has on both long sides the runners run obliquely upwards like a ramp Sections on so that the operations of both tarnishing to the rolls as well as the running of the Rolls are done softly and quietly, which makes the runnability the box on roller conveyors optimized and the noise is optimally reduced. It is the existing problem of non-demoldability the outer inclined surface by a different design loosened the bottom, which is flat in the middle, in the edge area above the runners, however, slightly outwards is formed increasing. Do not level these outwards rising parts of the ground are usually narrower than the flat middle part of the floor and have only a slight Deviation from the level up. The floor hangs under load in the middle, it falls Inclination of the edge area of the floor at all not on. For the transport of all kinds of bulk goods plays this inclination of the edge area of the floor no role at all for the transport of cuboid Goods only a minor one.

Bei diesem Transportkasten ist es vorteilhaft, wenn der geneigte Abschnitt des Bodens den gleichen Neigungswinkel wie der nach außen gerichtete Abschnitt der Kufe aufweist. Dann ist die Abweichung des Randbereiches des Bodens von der Ebene nur gering, die leichte Entformbarkeit jedoch gewähleistet. Es besteht jedoch auch die Möglichkeit, daß der geneigte Abschnitt des Bodens einen größeren Neigungswinkel als der nach außen gerichtete geneigte Abschnitt der Kufe aufweist, so daß eine im Querschnitt keilförmige sich nach außen hin erweiternde Bodentasche entsteht. With this transport case, it is advantageous if the inclined section of the floor the same angle of inclination like the outward section of the runner having. Then the deviation of the edge area of the Floor from the level only slight, the easy demoldability however guaranteed. However, there is also Possibility that the inclined portion of the floor unites greater angle of inclination than the one facing outwards Inclined portion of the skid, so that a cross-sectionally wedge-shaped towards the outside expanding bottom pocket is created.

Bei diesem Transportkasten kann es auch von Vorteil sein, daß der geneigte innere Abschnitt der Kufe gerundet ist, sein Neigungswinkel sich also laufend gegenüber der mittleren Kufenfläche verkleinert.With this transport case it can also be an advantage be that the inclined inner portion of the runner is rounded is, so its angle of inclination is constantly opposite the middle skid area reduced.

Um das Waschen der unter dem Boden befindlichen Taschen zu erleichtern, kann es bei diesem Transportkasten vorteilhaft sein, daß ein Spalt zwischen der Oberkante des nach oben gerichteten inneren Abschnittes der Kufe und dem Kastenboden befindlich ist, der ein Durchspülen der beidseitig offenen Taschen ermöglicht.To wash the bags under the floor to facilitate, it can be advantageous with this transport box be that there is a gap between the top edge of the upward inner portion of the runner and the bottom of the box is located, which is a flushing of the pockets open on both sides.

Eine besonders stabile Ausführung dieses Transportkastens wird erreicht, wenn der nach oben gerichtete innere Abschnitt der Kufe unmittelbar oder über eine Längsrippe in den Kastenboden übergeht.A particularly stable version of this transport box is achieved when the inner upward Section of the runner directly or via a longitudinal rib merges into the bottom of the box.

Der Transportkasten der Fig.1 besteht aus vier Seitenwänden 1, die an der Außenseite mit Rippen 2 und Handgrifflöchern 3 versehen sind, und einem Boden 4, der an seiner Unterseite mit Kufen 5 versehen ist, die mittels Querrippen 6 unter Bildung von Taschen 7 mit dem Boden 4 verbunden sind. Diese Taschen sind nach außen offen, sie können (müssen aber nicht) an der der Kastenmitte zugewandten Innenseite durch eine Längsrippe 8 verschlossen sein. Sind sie nicht durch eine Längsrippe 8 verbunden, befindet sich hier ein Spalt 21 für den Durchfluß von Waschwasser. Unter dem mittleren Bereich des Bodens 4 sind Verstärkungsrippen 9,10 angeordnet. Die unterste bodenparallele Rippe an der Außenseite der Seitenwände 1 bildet den sogenannten Stapelrand 11, mit dem ein auf einen anderen gleichgeformten Kasten gestapelter Transportkasten auf der obersten bodenparallelen Rippe 12 aufsitzt. Die äußere Kante der Querrippe 6 des oberen Kastens kommt dabei an der Innenwand des unteren Kastens zu liegen. Im gezeichneten Ausführungsbeispiel bilden die vier Kufen 5 einen umlaufenden Rahmen unter der Unterfläche des Bodens 4 (Fig.6). Die Kufen 5 weisen einen ebenen Teil 13 sowie an ihrer der Kastenmitte zugewandten Seite einen leicht schräg nach oben weisenden Teil 14 auf, der dem Transportkasten das Auflaufen auf die Röllchen einer Röllchenbahn erleichtert.The transport box of Fig.1 consists of four side walls 1, the outside with ribs 2 and handle holes 3 are provided, and a bottom 4, the its underside is provided with runners 5, which means Cross ribs 6 forming pockets 7 with the bottom 4 are connected. These pockets are open to the outside, they can (but do not have to) at the middle of the box facing inside closed by a longitudinal rib 8 his. Are they not through a longitudinal rib 8 connected, there is a gap 21 for the Flow of wash water. Under the middle area of the bottom 4, reinforcing ribs 9, 10 are arranged. The lowest rib parallel to the floor on the outside of the Side walls 1 form the so-called stacking edge 11, with one stacked on top of another of the same shape Transport box on the top parallel to the floor Rib 12 is seated. The outer edge of the transverse rib 6 of the the upper box comes on the inner wall of the lower one Box to lie. In the illustrated embodiment form the four runners 5 under a circumferential frame the bottom surface of the bottom 4 (Fig. 6). The runners 5 point a flat part 13 and at the middle of the box facing side a slightly obliquely upwards Part 14 on which the transport box accrues relieved on the rollers of a roller conveyor.

Dabei ist unter Röllchenbahn eine Transportbahn verstanden, die eine Vielzahl von in einem gemeinsamen Rahmen gelagerten Wellen aufweist, die jede mit etwa gleichem Seitenabstand von einander angeordnete schmale Rollen oder Räder (die Röllchen) tragen. Oftmals wechseln bei dieser Transportbahn aufeinanderfolgend Wellen mit einer geraden und einer ungeraden Röllchenzahl.The roller conveyor is understood to be a transport track which is a variety of in one common Has frame-mounted shafts, each with approximately equidistantly spaced from each other Wear rollers or wheels (the wheels). often change successively on this transport track Waves with an even and an odd number of rolls.

Bei dem erfindungsgemäßen Kasten sind der Boden 4 sowie die Kufen 5 in besonderer Weise gestaltet:

  • Die Kufen 5 weisen an ihrer der Kastenmitte abgewandten Außenseite neben dem ebenen Teil 13 einen weiteren leicht schräg nach oben weisenden Teil 15 auf, der dem Transportkasten ebenfalls das Auflaufen auf die Röllchen einer Röllchenbahn erleichtert.
  • Der Boden 4 dieses Transportkastens weist einen ebenen Mittelteil 16 und an den Rändern oberhalb der Kufen 5 leicht schräg nach oben außen ansteigende Seitenteile 17 auf, welche an ihrem äußeren, der Kastenmitte abgewandten Rand in die Seitenwände 1 übergehen. Diese ansteigenden Seitenteile 17 weisen denselben Steigungswinkel A wie der äußere Seitenteil 15 der Kufe 5 oder einen größeren Steigungswinkel auf. Dadurch ist es möglich, den Kern 18 der Herstellungsform zu entformen.
    • In the case of the box according to the invention, the bottom 4 and the runners 5 are designed in a special way:
  • The runners 5 have on their outer side facing away from the center of the box, in addition to the flat part 13, a further slightly inclined part 15, which also makes it easier for the transport box to run onto the rolls of a roll track.
  • The bottom 4 of this transport box has a flat middle part 16 and, at the edges above the runners 5, side parts 17 which rise slightly obliquely upwards and which merge into the side walls 1 on their outer edge facing away from the center of the box. These rising side parts 17 have the same pitch angle A as the outer side part 15 of the runner 5 or a larger pitch angle. This makes it possible to demold the core 18 from the production mold.

    • Denn dadurch ist erreicht, daß die am Teil 15 anliegende Flanke 19 des Kernes 18 parallel zu der Flanke 20 des Kernes 18 verläuft (oder unter einem spitzen Winkel steht). Mit anderen Worten: Der leicht nach außen oben ansteigende Randbereich 15 der Kufe 5 verläuft parallel zu dem Randbereich 17 des Bodens 4. Der Winkel A ist jeweils an der Kufe 5 und am Boden 4 kleiner als 180°, vorzugsweise 150 bis 170°. Der Winkel B an der Kufe 5 weist zweckmäßigerweise den gleichen oder einen ähnlichen Wert auf. Der Eckwinkel C zwischen Boden 4 und Seitenwand 1 ist demzufolge größer als 90°, was die Reinigung der Ecken erleichtert.Because this ensures that the part 15 is present Flank 19 of core 18 parallel to flank 20 of core 18 extends (or at an acute angle stands). In other words: the slightly outward upward rising edge area 15 of the runner 5 runs parallel to the edge region 17 of the bottom 4. The angle A is each on the runner 5 and on the floor 4 less than 180 °, preferably 150 to 170 °. The angle B on the runner 5 expediently has the same or a similar one Value on. The corner angle C between floor 4 and Sidewall 1 is therefore greater than 90 °, which is the Cleaning the corners easier.

    Die Längsrippe 8 ist in den meisten Anwendungsfällen nicht notwendig. An ihrer Stelle kann sich ein Spalt 21 befinden, der eine Reinigung der Bodentaschen 7 erleichtert, weil er eine Wasserablaufmöglichkeit bietet.The longitudinal rib 8 is in most applications unnecessary. In its place, a gap 21 are located, which facilitates cleaning of the bottom pockets 7, because it offers a drainage option.
