Description

Die Neuerung betrifft eine Stirnwand aus formbarem Material für eine Wickelrolle mit einer rechteckigen, insbesondere quadratischen, abgerundete Eckflächen aufweisenden Platte, deren der Wickelrolle zugewandte Vorderseite eine glatte, ebene Fläche bildet und deren nach außen von der Wickelrolle wegweisende Rückseite durch Radial- und Ringrippen versteift ist, mit einem zentralen Einsteckzapfen und Arretiernocken auf der Vorderseite der Platte.The innovation relates to an end wall made of mouldable material for a winding roll with a rectangular, in particular square, rounded corner surface plate, the front of which faces the winding roll forms a smooth, flat surface and the back of which points away from the winding roll is stiffened by radial and annular ribs , with a central insertion pin and locking cams on the front of the plate.

Stirnwände der gattungsgemäßen Art aus Kunststoff oder einem sonstigen formbaren Werkstoff zur Verpackung von auf Aufwickelhülsen gewickeltem Wickelgut, beispielsweise Kunststoffolien, sind aus der EP-A-0 332 186 bekannt. Jeweils zwei derartige Stirnwände bilden beidseitig auf die Aufwickelhülse aufgesetzt eine formsteife Gesamtverpackung einer Wickelrolle.End walls of the generic type made of plastic or another mouldable material for packaging winding material wound on winding cores, for example plastic films, are known from EP-A-0 332 186. Two such end walls form a dimensionally stable overall packaging of a winding roll when placed on both sides of the winding tube.

Bei dem bestimmungsgemäßen Einsatz derartiger Stirnwände, insbesondere beim Transport größerer und schwerer Einheiten auf Transportpaletten aus Holz, hat sich in der Praxis herausgestellt, daß die mechanische Höchstbelastbarkeit der Werkstoffe für die Stirnwände im Bereich seitlich angebrachter Stapelnocken mitunter überschritten wird. Derartige Überschreitungen führten zu Beschädigungen der Stirnwände an den besagten Stapelnocken, weiter zur Unbrauchbarkeit der Stirnwände und in seltenen Fällen sogar zu Beschädigungen des Packgutes, was unter allen Umständen vermieden werden muß.In the intended use of such end walls, in particular when transporting larger and heavier units on wooden transport pallets, it has been found in practice that the maximum mechanical strength of the materials for the end walls in the area of side-mounted stacking cams is sometimes exceeded. Such exceedances led to damage to the end walls of the stacking cams, further to the unusability of the end walls and in rare cases even to damage to the packaged goods, which must be avoided under all circumstances.

Die Aufgabe der Neuerung bestand darin, Stirnwände der eingangs beschriebenen Art so zu verbessern, daß nicht nur eine gegenseitige Arretierung der Stirnwände mehrerer aufeinander und/oder nebeneinander gestapelter kompletter Rollen, die von den Stirnwänden abgeschlossen sind, gewährleistet ist, sondern daß zusätzlich auch Beschädigungen durch mechanische Einwirkung beim Transport mit Transportpaletten vermieden werden.The object of the innovation was to improve end walls of the type described in the introduction in such a way that not only mutual locking of the end walls of a plurality of complete rolls stacked on top of one another and / or next to one another, which are sealed off from the end walls, is ensured, but also that damage was additionally caused by mechanical influences during transport with transport pallets can be avoided.

Diese Aufgabe wird neuerungsgemäß dadurch gelöst, daß auf wenigstens zwei der vier Seitenwände der Platte Stapelnocken vorhanden sind, die Stapeltaschen begrenzen, wobei die Stapeltaschen komplementär zu den Stapelnocken ausgebildet sind, so daß beim seitlichen Zusammenstapeln und/oder vertikalen Übereinanderstapeln senkrecht ausgerichteter Stirnwände die Stapelnocken und -taschen einer Seitenwand einer Stirnwand fugenlos mit den Stapeltaschen und -nocken der Seitenwand einer weiteren Stirnwand zusammenfügbar sind, und daß mindestens eine Seitenwand der Platte von einer ebenen Fläche gebildet ist.According to the invention, this object is achieved in that stacking cams are present on at least two of the four side walls of the plate and limit the stacking pockets, the stacking pockets being complementary to the stacking cams, so that when stacking and / or stacking vertical end walls vertically aligned end walls, the stacking cams and pockets of a side wall of an end wall can be joined together seamlessly with the stack pockets and cams of the side wall of a further end wall, and that at least one side wall of the plate is formed by a flat surface.

Vorzugsweise sind wenigstens zwei gegenüberliegende Seitenwände der Platte mit Stapelnocken und Stapeltaschen versehen, besonders bevorzugt drei.At least two opposite side walls of the plate are preferably provided with stacking cams and stacking pockets, particularly preferably three.

In Weiterbildung der Neuerung sind im Bereich der ebenen Fläche Vorsprünge angeordnet, die ein Verrutschen einer mit den neuerungsgemäßen Stirnwänden verpackten Wickelrolle auf den Planken einer Transportpalette verhindern. Die Vorsprünge besitzen vorzugsweise die Form von nach oben, d. h. von der ebenen Fläche der Seitenwand nach außen wegweisend, sich verjüngender geometrischer Figuren wie Kegel oder Stege, die parallel zueinander oder schräg kreuzweise, durchgehend oder unterbrochen in der Ebene der Seitenwand angeordnet sein können.In a further development of the innovation, projections are arranged in the area of the flat surface, which prevent a winding roll packed with the end walls according to the invention from slipping on the planks of a transport pallet. The protrusions are preferably in the form of after above, ie pointing outwards from the flat surface of the side wall, tapering geometric figures such as cones or webs, which can be arranged parallel to one another or obliquely crosswise, continuously or interrupted in the plane of the side wall.

In Ausgestaltung der Neuerung weisen die Stapelnocken angeschrägte Seitenflächen auf, die zur Mittellinie der Seitenwand hin geneigt sind, und fluchten paarweise Stapelnocken mit der Oberkante und mit der Unterkante einer Seitenwand.In an embodiment of the innovation, the stacking cams have tapered side surfaces which are inclined towards the center line of the side wall, and are aligned in pairs with the top edge and the bottom edge of a side wall.

Mit der Neuerung wird der Vorteil erzielt, daß die Stapelnocken und Stapeltaschen der Stirnwände so ineinandergreifen, daß ein Verschieben der aufeinander und/oder nebeneinander gestapelten kompletten Rollen mit den begrenzenden Stirnwänden längs oder quer nicht möglich ist. Die angeschrägten Seitenflächen der Stapelnocken und Stapeltaschen erlauben ein problemloses Stapeln und Entstapeln der mit diesen Stirnwänden verpackten Rollen.With the innovation, the advantage is achieved that the stacking cams and stacking pockets of the end walls intermesh in such a way that it is not possible to move the complete rolls stacked one above the other and / or next to one another with the delimiting end walls lengthways or crosswise. The bevelled side surfaces of the stacking cams and stacking pockets allow the rolls packed with these end walls to be stacked and destacked without any problems.

Ein weiterer Vorteil der neuerungsgemäßen Stirnwand ist darin zu sehen, daß die Seite, die beim bestimmungsgemäßen Einsatz der Stirnwand der Transportpalette zugewandt ist, aufgrund ihrer ebenen Ausbildung die auftretenden druckbelastungen besser verteilen kann, wodurch Beschädigungen der Stirnwand oder gar des Packgutes nicht mehr vorkommen können.Another advantage of the new end wall can be seen in the fact that the side facing the transport pallet when the end wall is used as intended can better distribute the pressure loads that occur due to its level design, as a result of which damage to the end wall or even the packaged goods can no longer occur.

Die Erfindung wird im folgenden anhand eines zeichnerisch dargestellten Ausführungsbeispiels näher erläutert.
   Es zeigen:

Fig. 1
schematisch eine Teilansicht einer neuerungsgemäßen Stirnwand von oben,
Fig. 2
eine seitliche Ansicht der Seite einer neuerungsgemäßen Stirnwand, die als ebene Fläche ausgebildet ist.
The invention is explained in more detail below with reference to an exemplary embodiment shown in the drawing.
Show it:
Fig. 1
schematically a partial view of an end wall according to the invention from above,
Fig. 2
a side view of the side of a new end wall, which is designed as a flat surface.

Wie aus der schematischen Darstellung der Figur 1 ersichtlich ist, sind die Eckflächen 15 der Stirnwand 1 abgerundet, und die zylindrischen Arretiernocken 4 sind mit diesen Eckflächen integriert und haben den gleichen Radius wie die abgerundeten Eckflächen 15. Die Darstellung zeigt auf der Rückseite der Stirnwand 1, die von der Wickelrolle abgewandt ist und nach außen weist, Radialrippen 5 und Ringrippen 14, welche die Rückseite versteifen und große Wandstärken vermeiden, so daß das Stückgewicht der Stirnwand 1 gering gehalten werden kann. Die Radial- und Ringrippen ergeben eine hohe Belastbarkeit der Stirnwand 1 bei geringem Eigengewicht. An zweien der in Figur 1 nur unvollständig dargestellten Seiten 13 der Stirnwand 1 sind Stapelnocken 9 und 19 und Stapeltaschen 8, 18, angeordnet, die komplementär zu den Stapelnocken ausgebildet sind. Die dritte dargestellte Seite 12 ist als ebene Fläche ausgebildet, die in der Darstellung als Stege ausgebildete Vorsprünge 6 trägt.As can be seen from the schematic illustration in FIG. 1, the corner surfaces 15 of the end wall 1 are rounded, and the cylindrical locking cams 4 are integrated with these corner surfaces and have the same radius as the rounded corner surfaces 15. The illustration shows on the back of the end wall 1 , which faces away from the winding roll and points outwards, radial ribs 5 and ring ribs 14, which stiffen the back and avoid large wall thicknesses, so that the piece weight of the end wall 1 can be kept low. The radial and ring ribs result in a high load capacity of the end wall 1 with a low weight. Stacking cams 9 and 19 and stacking pockets 8, 18 are arranged on two of the sides 13 of the end wall 1, which are only incompletely shown in FIG. 1, and are designed to be complementary to the stacking cams. The third side 12 shown is designed as a flat surface, which in the illustration carries projections 6 designed as webs.

Wie aus Figur 2 ersichtlich ist, weist die Platte 11 eine zentrale zylindrische Durchgangsöffnung 12 auf. Der hohlzylindrische Einsteckzapfen 2 ist mit dieser zentralen Durchgangsöffnung 12 verbunden. Der Durchmesser der Durchgangsöffnung 12 ist größer als der Außendurchmesser des Einsteckzapfens 2. An der Außenfläche des Einsteckzapfens 2 verlaufen parallel zur Längsachse des Einsteckzapfens V-förmige Stege 3, die zur Vorderseite der Platte 11 hin kleiner werdenden Querschnitt besitzen. Der Einsteckzapfen 2 wird in die Bohrung der nicht dargestellten Aufwickelhülse eingedrückt. Die V-förmigen Stege 3 auf dem Einsteckzapfen 2 gewährleisten einen besseren Halt des Einsteckzapfens in der Aufwickelhülse und gleichen Dimensionstoleranzen der Aufwickelhülse einerseits und des Einsteckzapfens andererseits aus. Die Vorsprünge 6 sind in Figur 2 besser als Stege erkennbar.As can be seen from FIG. 2, the plate 11 has a central cylindrical through opening 12. The hollow cylindrical Insert pin 2 is connected to this central through opening 12. The diameter of the through hole 12 is larger than the outer diameter of the insertion pin 2. V-shaped webs 3 run on the outer surface of the insertion pin 2 parallel to the longitudinal axis of the insertion pin and have a cross section that becomes smaller towards the front of the plate 11. The insertion pin 2 is pressed into the bore of the winding sleeve, not shown. The V-shaped webs 3 on the insertion pin 2 ensure a better hold of the insertion pin in the winding tube and the same dimensional tolerances of the winding tube on the one hand and the insertion pin on the other. The projections 6 can be seen better in FIG. 2 as webs.
