Description
Die Erfindung betrifft einen Wickelring nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a winding ring according to the preamble of patent claim 1.
Wickelringe (Wickelhülsen) üblicher Art werden aus einem Kunststoff hergestellt (in der Regel PS, PP, HDPE, LDPE, PA), der über keine Verstärkung mit Naturfasern verfügt.Wickelringe (winding cores) usual type are made of a plastic (usually PS, PP, HDPE, LDPE, PA), which has no reinforcement with natural fibers.
Diese Wickelringe (Wickelhülsen) weisen in der Regel die Problematik auf, dass sie über eine gewisse Maßtoleranz verfügen, die sich aus dem Schwingungsverhalten des eingesetzten Kunststoffes ergibt. Diese Maßtoleranzen der einzelnen Wickelringe (Wickelhülsen) wirken sich negativ auf die Produktion aus, da in der Produktion jeweils ca. 30 bis 50 Stück Wickelringe (Wickelhülsen) auf eine starre Spannwelle gespannt werden, die in drei Segmente a 120° geteilt ist und hydraulisch oder pneumatisch die Wickelringe (Wickelhülsen) spannt. Durch Maßtoleranzen in den Wickelringen (Wickelhülsen) kann es vorkommen, dass von den ca. 30 bis 50 Stück zu spannenden Wickelringen (Wickelhülsen) einige bei diesem Prozess nicht richtig auf der Spannwelle gespannt werden und durchrutschen. Durch Erhöhen des hydraulischen oder pneumatischen Drucks auf die Spannwelle kann die Spannwelle sich in einem gewissen Maß noch weiter öffnen, um den Spanndruck zu erhöhen, was sich aber negativ auf die schon gespannten Wickelringe (Wickelhülsen) auswirken kann, da diese nun ein zu hohen Spanndruck erhalten und an der Stelle des Zusammenflusses der Spritzgussmasse reißen können.This winding rings (cores) usually have the problem that they have a certain dimensional tolerance, resulting from the vibration behavior of the plastic used. These dimensional tolerances of the individual winding rings (cores) have a negative effect on the production, since in production about 30 to 50 winding rings (cores) are clamped on a rigid clamping shaft, which is divided into three segments a 120 ° and hydraulic or pneumatically clamped the winding rings (cores). Due to dimensional tolerances in the winding rings (cores), it can happen that some of the approx. 30 to 50 pieces of exciting winding rings (cores) are not properly tensioned and slipped on the tensioning shaft during this process. By increasing the hydraulic or pneumatic pressure on the tensioning shaft, the tensioning shaft can open further to a certain extent in order to increase the tensioning pressure, which can, however, have a negative effect on the already tensioned winding rings (winding sleeves) since these now have too high a tensioning pressure and tear at the point of confluence of the injection molding compound.
Auch verfügen dieses Wickelringe (Wickelhülsen) nur über eine gewisse Stabilität in Abhängigkeit von ihrer Wandstärke. Hierdurch kann es zur Verformung des Wickelringes (Wickelhülse) und des aufgewickelten Materials kommen, wenn der Wickelring (Wickelhülse) nach dem Bewickeln von der Spannwelle benommen wird.Also, these winding rings (cores) only have a certain stability depending on their wall thickness. This can lead to deformation of the winding ring (winding tube) and the wound material when the winding ring (winding tube) is behaved after winding of the clamping shaft.
Bekannte Wickelringe weisen in der Regel die Problematik auf, dass sie durch ihre glatte innere Oberfläche zum sogenannten Durchrutschen nach dem Spannprozess neigen können. Bei dem Spannprozess werden in der Regel ca. 30 bis 50 Wickelringe (Wickelhülsen) auf eine starre Spannwelle gespannt. Die Spannwelle besteht in der Regel aus drei Segmenten a 120°, die hydraulisch oder pneumatisch auseinander gefahren werden und so den Durchmesser der Spannwelle vergrößern, bis die Wickelringe (Wickelhülsen) fest auf der Spannwelle gespannt sind. Da die Spannwelle aus Stahl gefertigt ist und über eine gewisse Strukturoberfläche in Form von Rillen oder Karos verfügt, wird zwar durch den Spanndruck eine gewisse Festigkeit der Wickelringe (Wickelhülsen) auf der Spannrolle erzielt, der sich bei den Pappwickelringen (Pappwickelhülsen) auch noch etwas besser als bei der Version aus Kunststoff oder Biopolymer mit oder ohne Fasern darstellt. Doch durch die glatten Oberflächen, sowohl bei der Version aus Pappe als auch aus Kunststoff oder Biopolymer mit oder ohne Fasern, können einige Wickelringe (Wickelhülsen) trotzdem dazu neigen, wenn sie nicht optimal auf der Spannwelle gespannt sind, beim Wickelprozess nicht optimal mitzulaufen und so dadurch durchzurutschen.Known winding rings generally have the problem that they can tilt due to their smooth inner surface for so-called slipping after the clamping process. In the clamping process usually about 30 to 50 winding rings (cores) are clamped on a rigid clamping shaft. As a rule, the tensioning shaft consists of three 120 ° segments, which are moved apart hydraulically or pneumatically, thus increasing the diameter of the tensioning shaft until the winding rings (winding sleeves) are firmly clamped on the tensioning shaft. Since the clamping shaft is made of steel and has a certain structure surface in the form of grooves or checks, although the clamping pressure a certain strength of the winding rings (cores) on the tensioner achieved, which in the Pappwickelringen (cardboard wrapping) also slightly better as in the plastic or biopolymer version with or without fibers. However, due to the smooth surfaces, both in the version made of cardboard and plastic or biopolymer with or without fibers, some winding rings (cores) may tend, if they are not optimally stretched on the tensioning shaft, not optimally run during the winding process and so to slip through.
Aus der
Aufgabe der Erfindung ist es, einen Wickelring zu schaffen, der die Fixierung der Wickelringe auf der Spannwelle maßgebend verbessert.The object of the invention is to provide a winding ring, which significantly improves the fixation of the winding rings on the clamping shaft.
Zur Lösung weist die Erfindung die Merkmale des Patentanspruchs 1 auf.To solve the invention, the features of claim 1.
Mit der Erfindung wird erreicht, dass das sogenannte Durchrutschen der Wickelringe nach dem Spannprozess maßgeblich minimiert und dadurch der Produktionsprozess weiter optimiert und verbessert werden kann, da es zu weniger Ausschuss und Nachrüstzeit kommt..With the invention it is achieved that the so-called slipping of the winding rings after the tensioning process is significantly minimized and thereby the production process can be further optimized and improved, as it comes to less waste and retrofit time.
Nach einer Weiterbildung der Erfindung wird erreicht, dass das Schwingungsverhalten und die dadurch resultierenden Maßtoleranzen maßgeblich minimiert und dadurch eine gleichmäßigere Spannung der ca. 30 bis 50 Stück Wickelringe auf der Spannwelle erreicht wird. Durch eine bessere Vernetzung der Spritzgussmasse im Bereich des Zusammenflusses wird eine höhere Spannfestigkeit (Zugfestigkeit) der Wickelringe auf der Spannwelle erreicht. Durch den Faseranteil in den Wickelringen wird eine höhere Stabilität in Abhängigkeit von der Wandstärke erreicht, was zu einer geringeren Verformung der Wickelringe und des aufzuwickelnden Materials führt.According to a development of the invention it is achieved that the vibration behavior and the resulting dimensional tolerances significantly minimized and thereby a more uniform voltage of about 30 to 50 winding rings on the winding shaft is achieved. By better cross-linking of the injection molding compound in the area of the confluence, a higher tensile strength (tensile strength) of the winding rings is achieved on the tensioning shaft. Due to the fiber content in the winding rings a higher stability is achieved depending on the wall thickness, resulting in a lower deformation of the winding rings and the material to be wound.
