Definitions
- the present invention relates to a buffer spool for receiving a filament according to the preamble of claim 1 and a multiple spool cabinet for winding a number of filaments onto a transport spool according to the preamble of claim 7 DE 10 2009 026 849 B3 a multiple bobbin cabinet for winding a material to be wound onto a transport bobbin is known, which has two winding stations and a changing device, the filament is guided from the full transport reel of the first winding station through the changing device to the second winding station with an empty transport reel, so that the full transport reel can be removed and exchanged for an empty transport reel.
- a multiple bobbin cabinet for winding material to be wound onto a transport bobbin which has at least two spindles for each winding station for receiving a transport bobbin. Therefore, the material to be wound is first wound onto the transport reel located on the first spindle and when this is full, the material to be wound is directed onto the transport reel of the second spindle. Now the first full transport reel can be exchanged for an empty transport reel, etc.
- Such a multiple bobbin cabinet is, on the one hand, expensive and prone to failure because of the very complex changing device and, on the other hand, two winding stations arranged next to one another are required, one of which remains permanently unused, which requires a very high space requirement.
- manual multiple bobbin cabinet Multiple bobbin cabinets are also known in which the bobbin is changed manually (hereinafter referred to as manual multiple bobbin cabinet), so that an alternating bobbin device is unnecessary.
- manual multiple spool cabinets can accommodate significantly more transport spools with the same size and thus compensate for part of the additional costs incurred due to the manual change.
- the manual multiple spool cabinets can be made much smaller with the same number of spools, so that the free length of the filament from the extruder to the transport spool is shorter, which in turn results in less failure-prone operation, so that part of the additional costs incurred by the manual change can be compensated. So that the If the transport bobbin can be changed manually, the infeed speed of the filament must be limited to a maximum of 180 m / min in order to avoid injuries to the operator.
- the present invention is based on the object of creating a manual multiple bobbin cabinet of the type mentioned at the beginning, which can be operated at a higher inlet speed.
- the invention proposes a buffer reel of the type mentioned with the features of claim 1 and a manual multiple coil cabinet of the type mentioned with the features of claim 7.
- Advantageous further developments of this buffer coil and this multiple coil cabinet can be found in the respective subclaims.
- a manual multiple reel cabinet designed according to this technical teaching has the advantage that a second reel, namely a buffer reel, is held on the already existing main winding shaft, on which the filament is wound while the full transport reel is exchanged for an empty transport reel. This eliminates the need for a second winding station, as a result of which the multiple bobbin cabinet can either be made significantly smaller or as a result of which significantly more transport bobbins can be operated in parallel.
- Another advantage is that the infeed speed of the filament, depending on the thickness of the filament, can be increased to up to 800 m / min due to the buffer bobbin, which significantly increases the efficiency of the manual multiple bobbin cabinet.
- the change of a transport spool is carried out as follows: As soon as the transport spool has been filled in the desired way, the filament is diverted manually into the buffer spool by an operator. Then the filament is cut and the full transport spool is removed. Then an empty transport spool is placed on the main winding shaft and the filament is again guided back by hand by the operator from the buffer spool to the transport spool, so that from now on the filament is rewound onto the transport spool. The filament located between the buffer reel and the transport reel is then cut through. As soon as this transport reel is full again, this process is repeated. The filament wound onto the buffer reel during the change process remains permanently on this buffer reel until the buffer reel is full after several change processes. Only now is the buffer reel removed and replaced with an empty buffer reel, so that the filament outside the multiple reel cabinet can be removed from the buffer reel in peace.
- 30 to 80 changes can be carried out until the buffer reel is full and has to be replaced.
- the buffer reel is driven independently of the main winding shaft, in particular via a separate electric drive which is operatively connected to the buffer reel via a belt.
- a buffer spool designed according to this technical teaching for attachment to a manual multiple spool cabinet comprises a spool core, a spool wall, a side wall and a catching device for capturing the filament, the spool core being limited to the multiple spool cabinet by the side wall, while the spool core is limited to the transport spool by the coil wall is limited.
- the bobbin itself is dimensioned so that the filaments can be picked up from 30 to 80 transport bobbin changes, that is, the bobbin is significantly shorter than the comparable bobbin of the transport bobbin.
- the catching device supports the change of the filament from the transport reel to the buffer reel and advantageously has a circumferential catching surface that radially adjoins the bobbin wall and / or the side wall, the catching surface leading an impinging filament to the coil core.
- such a catching surface for catching the filament adjoins both the side wall and the spool wall radially. It has been shown to be beneficial to that Make the side wall with the associated catching surface larger than the coil wall with the associated catching surface, because the smaller catching surface on the coil wall makes it easier to transfer the filament, while the slightly larger catching surface on the side wall reliably catches the filament.
- This catching surface is advantageously not aligned exactly radially, but aligned inclined, in particular aligned inclined away from the coil core. This has the advantage that it enlarges the entry area relevant for the filament. Another advantage is that the inclined catching surface guides a filament that strikes it towards the spool core.
- the angle of the catching surface to the longitudinal axis of the main winding shaft is advantageously between 20 ° and 45 °, preferably 30 °.
- the safety device in particular a radially outer edge of the safety device, extends over a part of the transport reel, in particular over the transport reel side wall. This facilitates the transfer of the filament from the rotating transport reel to the rotating buffer reel, because this reliably prevents the filament from accidentally sliding off during the transfer into an area between the transport reel and the buffer reel. Rather, the filament arrives at the projecting catching surface and is continued by this to the core of the buffer coil.
- a circumferential safety shoulder is formed on the safety device, in particular on the radially outer edge of the safety device, which is preferably designed as an edged or knurled edge of the safety device.
- this safety shoulder is designed as a circumferential thickening, this has the advantage that it is a sharp-edged end of the safety device is avoided, so that on the one hand the operator cannot injure himself and on the other hand that the filament is not accidentally cut when changing from the transport reel to the buffer reel.
- the side wall and / or the coil wall is designed to be completely inclined and thus simultaneously forms the catching surface of the catching device.
- the safety gear inclined away from the coil core extends to the coil core, so that the actual side wall can be dispensed with. This simplifies the manufacture of such a coil.
- the coil core is designed to taper conically towards the transport coil. This has the advantage that the filaments accumulating on the spool core collect at the lowest point of the spool core, thus avoiding tangling or accidental loosening of the filaments located in the spool.
- FIG. 1 shows part of a manual multiple bobbin cabinet for winding a number of filaments onto a transport bobbin each, with FIG Fig. 1 a main winding shaft 10, a buffer reel 12 which can be mounted on the main winding shaft 10 and a transport reel 14 driven by the main winding shaft 10 are shown. It goes without saying that there are up to 100 such main winding shafts with buffer bobbins 12 and transport bobbins 14 to be accommodated on such a multiple reel cabinet.
- the illustrated first embodiment of a buffer reel 12 comprises a reel core 16, a radially protruding side wall 18 delimiting the reel core 16 towards the multiple reel cabinet, a radially projecting reel wall 20 delimiting the reel core 16 towards the transport reel 14 and a pulley firmly attached to the buffer reel 12 22 for receiving a belt of an electric drive.
- the buffer reel 12 has various roller bearings (not shown here) in its interior, so that the buffer reel 12 sits freely on the main winding shaft 10.
- the main winding shaft 10 is made so long that, in addition to the buffer reel 12, the transport reel 14 can also be held precisely and reliably on the main winding shaft 10.
- the transport reel 14 comprises a transport reel core 24 for receiving the filament, which is delimited by a right and a left, radially protruding transport reel side wall 26a, 26b.
- a catch device 28 is provided which has a circumferential catch surface 30, a circumferential one Has safety shoulder 32 and a circumferential annular groove 34.
- the catch surface 30 adjoins the side wall 18 at the radially outer edge and is inclined away from the spool core 16 in the axial direction, the angle to the longitudinal axis of the main winding shaft 10 being between 20 ° and 45 °, preferably 30 °.
- a circumferential annular groove 34 is formed at the free end of the catch surface 30, as shown in particular in FIG Fig. 1a is easy to see.
- a circumferential safety shoulder 32 adjoins the radial, free end of the annular groove 34.
- Such a structurally identical catching device 28 is also provided on the spool wall 20 in the embodiment shown.
- Fig. 2 shows part of the multiple reel cabinet with two main winding shafts 10, 10a arranged next to one another and with buffer reels 12, 12a and transport reels 14, 14a placed thereon.
- the buffer reel 12 held freely on the main winding shaft 10 is driven by a separate electric drive 36, the electric drive 36 being connected to the buffer reel 12 via a belt 38 seated in the pulley 22.
- the buffer coil 12a is driven by a separate electric drive 36, the electric drive 36 being connected to the buffer reel 12 via a belt 38 seated in the pulley 22.
- the buffer coil 12a is driven by a separate electric drive 36, the electric drive 36 being connected to the buffer reel 12 via a belt 38 seated in the pulley 22.
- the side wall 18 with the safety device 28 attached to it is made somewhat larger than the coil wall 20 with the safety device 28a attached thereto.
- the catching device 28a of the reel wall 20 extends clearly to over the transport reel side wall 26a of the transport reel 24, so that the gap between the buffer reel 12 and the transport reel 14 is thereby covered.
- the safety shoulder 32 is designed as a circumferential thickening and is thus intended to prevent injury to the operator or accidental severing of the filament.
- the circumferential annular groove 34 of the catching device 28 is intended to prevent filaments on the catching surface 30 from moving away from the buffer spool 12. As soon as these filaments arrive at the annular groove 34, they are stopped accordingly. Rather, the catch surface 30, which is inclined between 20 ° and 45 °, preferably 30 °, with respect to the longitudinal axis of the main winding shaft 10 is intended to cause a filament that strikes it to be guided to the spool core 16.
- the filament 40 is now wound onto the buffer reel 12.
- the transport spool 14 can be removed from the main winding shaft 10 and, as in FIG Figure 3c can be seen to be replaced by an empty transport reel 14.
- the parallel transport spool 14a on the main winding shaft 10a remains unaffected by this and continues to pick up another filament 40a in the usual manner at a speed of up to 800 m / min.
- the operator guides the filament 40 from the buffer reel 12 onto the empty transport reel 14 and then cuts through the filament 40 so that the filament 40 is well wound onto the transport reel 14 in the usual manner. During this process, part of the filament 40 has wound onto the buffer spool 12 and remains there.
- the electric drive 36 is switched off so that the buffer reel 12 does not rotate permanently.
- the buffer reel 12 is designed in such a way that about 30 to 80 transport reel changes can be carried out before the buffer reel 12 is full and has to be emptied itself. This entire process takes place during ongoing operation, the filament 40 being wound onto the transport reel 14 at a speed of up to 800 m / min.
- a second embodiment of a buffer reel 112 according to the invention is shown, in which a side wall and a reel wall have been dispensed with and the catching device 128 is arranged directly protruding from the reel core 116 and inclined away from the reel core 116.
- the catch devices 128 are both identical and also have a catch surface 130, a securing shoulder 132 and an annular groove 134.
- a third embodiment of a buffer coil 212 according to the invention is shown, which except for the coil core 216 is identical to that in the Figures 1 and 2 illustrated first embodiment of the buffer coil 12 is.
- the coil core 216 of the buffer coil 212 is conically tapered, the narrow end being configured towards the transport reel 214.

Abstract
Gegenstand der Erfindung ist ein manueller Mehrfachspulenschrank zum Aufspulen einer Anzahl von Filamenten (40, 40a) auf jeweils eine abnehmbare Transportspule (14, 14a), mit einer angetriebenen Hauptwickelwelle (10, 10a) je Transportspule (14, 14a), wobei die Hauptwickelwelle (10, 10a) zur passgenauen Aufnahme der Transportspule (14, 14a) ausgebildet ist und wobei die Hauptwickelwelle (10, 10a) die Transportspule (14, 14a) antreibt. Einen solchen manuellen Mehrfachspulenschrank zu schaffen, der eine erhöhte Filamentgeschwindigkeit aufweist wird dadurch erreicht, dass auf der Hauptwickelwelle (10, 10a) neben der Transportspule (14, 14a) eine Pufferspule (12, 12a) gehalten ist.The invention relates to a manual multiple spool cabinet for winding a number of filaments (40, 40a) onto a removable transport spool (14, 14a), with a driven main winding shaft (10, 10a) for each transport spool (14, 14a), the main winding shaft ( 10, 10a) is designed for precisely fitting the transport reel (14, 14a) and wherein the main winding shaft (10, 10a) drives the transport reel (14, 14a). Creating such a manual multiple spool cabinet with increased filament speed is achieved by holding a buffer spool (12, 12a) on the main winding shaft (10, 10a) next to the transport spool (14, 14a).
Description

Ein solcher Mehrfachspulenschrank ist zum Einen wegen der sehr komplexen Wechseleinrichtung kostenintensiv und störanfällig und zum Anderen werden zwei nebeneinander angeordnete Spulstationen benötigt, von denen eine permanent ungenutzt bleibt, was einen sehr hohen Platzbedarf erfordert.Such a multiple bobbin cabinet is, on the one hand, expensive and prone to failure because of the very complex changing device and, on the other hand, two winding stations arranged next to one another are required, one of which remains permanently unused, which requires a very high space requirement.
Auch sind Mehrfachspulenschränke bekannt, bei denen der Wechsel der Spule manuell erfolgt (nachfolgend manueller Mehrfachspulenschrank genannt), sodass eine Wechselspuleinrichtung entbehrlich ist. Diese manuellen Mehrfachspulenschränke können bei gleicher Größe deutlich mehr Transportspulen aufnehmen und so einen Teil der die durch den manuellen Wechsel anfallenden Mehrkosten kompensieren. Alternativ können die manuellen Mehrfachspulenschränke bei gleicher Spulenzahl sehr viel kleiner gebaut werden, sodass die freie Länge des Filamentes vom Extruder zur Transportspule kürzer wird, was wiederum einen weniger störanfälligen Betrieb bewirkt, sodass ein Teil der durch den manuellen Wechsel anfallenden Mehrkosten kompensiert werden kann. Damit der Wechsel der Transportspule manuell erfolgen kann, muss die Einlaufgeschwindigkeit des Filamentes auf maximam 180 m/min beschränkt werden, um Verletzungen des Bedieners zu vermeiden.Multiple bobbin cabinets are also known in which the bobbin is changed manually (hereinafter referred to as manual multiple bobbin cabinet), so that an alternating bobbin device is unnecessary. These manual multiple spool cabinets can accommodate significantly more transport spools with the same size and thus compensate for part of the additional costs incurred due to the manual change. Alternatively, the manual multiple spool cabinets can be made much smaller with the same number of spools, so that the free length of the filament from the extruder to the transport spool is shorter, which in turn results in less failure-prone operation, so that part of the additional costs incurred by the manual change can be compensated. So that the If the transport bobbin can be changed manually, the infeed speed of the filament must be limited to a maximum of 180 m / min in order to avoid injuries to the operator.
Davon ausgehend liegt der vorliegenden Erfindung die Aufgabe zugrunde, einen manuellen Mehrfachspulenschrank der eingangs genannten Art zu schaffen, der mit einer höheren Einlaufgeschwindigkei betrieben werden kann.Proceeding from this, the present invention is based on the object of creating a manual multiple bobbin cabinet of the type mentioned at the beginning, which can be operated at a higher inlet speed.
Als technische Lösung dieser Aufgabe wird erfindungsgemäß eine Pufferspule der eingangs genannten Art mit den Merkmalen des Anspruches 1 und ein manueller Mehrfachspulenschrank der eingangs genannten Art mit den Merkmalen des Anspruches 7 vorgeschlagen. Vorteilhafte Weiterbildungen dieser Pufferspule und dieses Mehrfachspulenschrankes sind den jeweiligen Unteransprüchen zu entnehmen.As a technical solution to this problem, the invention proposes a buffer reel of the type mentioned with the features of claim 1 and a manual multiple coil cabinet of the type mentioned with the features of claim 7. Advantageous further developments of this buffer coil and this multiple coil cabinet can be found in the respective subclaims.
Ein nach dieser technischen Lehre ausgebildeter manueller Mehrfachspulenschrank hat den Vorteil, dass auf der ohnehin schon vorhandenen Hauptwickelwelle nun noch eine zweite Spule, nämlich eine Pufferspule gehalten ist, auf der das Filament aufgewickelt wird, während die volle Transportspule gegen eine leere Transportspule gewechselt wird. Somit entfällt die Notwendigkeit einer zweiten Spulstation, wodurch der Mehrfachspulenschrank entweder deutlich kleiner ausgeführt werden kann oder wodurch deutlich mehr Transportspulen parallel betrieben können.A manual multiple reel cabinet designed according to this technical teaching has the advantage that a second reel, namely a buffer reel, is held on the already existing main winding shaft, on which the filament is wound while the full transport reel is exchanged for an empty transport reel. This eliminates the need for a second winding station, as a result of which the multiple bobbin cabinet can either be made significantly smaller or as a result of which significantly more transport bobbins can be operated in parallel.
Ein weiterer Vorteil besteht darin, dass durch die Pufferspule die Einlaufgeschwindigkeit des Filamentes, je nach Dicke des Filamentes, auf bis zu 800 m/min gesteigert werden, wodurch die Effizienz des manuellen Mehrfachspulenschrankes signifikant erhöht wird.Another advantage is that the infeed speed of the filament, depending on the thickness of the filament, can be increased to up to 800 m / min due to the buffer bobbin, which significantly increases the efficiency of the manual multiple bobbin cabinet.
Der Wechsel einer Transportspule wird wie folgt ausgeführt: Sobald die Transportspule in der gewünschten Weise aufgefüllt ist, wird das Filament von einem Bediener per Hand in die Pufferspule umgeleitet. Anschließend wird das Filament durchtrennt und die volle Transportspule entnommen. Danach wird eine leere Transportspule auf der Hauptwickelwelle aufgebracht und das Filament wird wieder durch den Bediener von Hand von der Pufferspule auf die Transportspule zurückgeleitet, sodass fortan das Filament wieder auf die Transportspule aufgewickelt wird. Anschließend wird noch das zwischen der Pufferspule und der Transportspule befindliche Filament durchtrennt. Sobald diese Transportspule wieder voll ist, wird dieser Vorgang wiederholt. Dabei verbleibt das während des Wechselvorganges auf die Pufferspule aufgewickelte Filament dauerhaft auf dieser Pufferspule, bis die Pufferspule nach mehreren Wechselvorgängen voll ist. Erst jetzt wird auch die Pufferspule entnommen und gegen eine leere Pufferspule ersetzt, so dass das Filament außerhalb des Mehrfachspulenschrankes in aller Ruhe wieder von der Pufferspule entfernt werden kann.The change of a transport spool is carried out as follows: As soon as the transport spool has been filled in the desired way, the filament is diverted manually into the buffer spool by an operator. Then the filament is cut and the full transport spool is removed. Then an empty transport spool is placed on the main winding shaft and the filament is again guided back by hand by the operator from the buffer spool to the transport spool, so that from now on the filament is rewound onto the transport spool. The filament located between the buffer reel and the transport reel is then cut through. As soon as this transport reel is full again, this process is repeated. The filament wound onto the buffer reel during the change process remains permanently on this buffer reel until the buffer reel is full after several change processes. Only now is the buffer reel removed and replaced with an empty buffer reel, so that the filament outside the multiple reel cabinet can be removed from the buffer reel in peace.
Entsprechend der Aufnahmekapazität der Pufferspule und in Abhängigkeit der Dicke des Filamentes können 30 bis 80 Wechselvorgänge durchgeführt werden, bis die Pufferspule voll ist und getauscht werden muss.Depending on the capacity of the buffer reel and depending on the thickness of the filament, 30 to 80 changes can be carried out until the buffer reel is full and has to be replaced.
Dabei hat es sich als vorteilhaft herausgestellt, die Pufferspule freilaufend auf der Hauptwickelwelle zu halten, weil hierdurch die Drehzahl der Pufferspule unabhängig von der Drehzahl der Transportspule eingestellt werden kann und weil hierdurch die Pufferspule auch festgestellt werden kann. Um einen störungsfreien Transport der vielen Filamente eines Mehrfachspulenschrankes vom Extruder zu der jeweiligen Transportspule zu gewährleisten, ist eine konstante Einlaufgeschwindigkeit des Filamentes wichtig. Weil sich aber der Wickeldurchmesser der Transportspule ändert, erfolgt eine Drehzahlanpassung der Transportspule, um die Einlaufgeschwindigkeit konstant zu halten. Damit auch die Drehzahl der Pufferspule entsprechend ihrem Füllstand an die Einlaufgeschwindigkeit angepasst werden kann, ist die Pufferspule freilaufend auf der Hauptwickelwelle gehalten.It has been found to be advantageous to keep the buffer reel free-running on the main winding shaft because this allows the speed of the buffer reel to be set independently of the speed of the transport reel and because this also enables the buffer reel to be determined. In order to ensure trouble-free transport of the many filaments of a multiple spool cabinet from the extruder to the respective transport spool, a constant entry speed of the filament is important. However, because the winding diameter of the transport reel changes, the speed of the transport reel is adjusted in order to keep the infeed speed constant. This also applies to the speed of the buffer coil can be adapted to the infeed speed according to its fill level, the buffer reel is kept free-running on the main winding shaft.
In einer bevorzugten Ausführungsform wird die Pufferspule unabhängig von der Hauptwickelwelle angetrieben, insbesondere über einen separaten Elektroantrieb, der über einen Riemen mit der Pufferspule wirkverbunden ist. Dies hat den Vorteil, dass über den eigenen Elektroantrieb die Drehzahl der Pufferspule unabhängig von der Transportspule an die Einlaufgeschwindigkeit des Filamentes angepasst werden kann.In a preferred embodiment, the buffer reel is driven independently of the main winding shaft, in particular via a separate electric drive which is operatively connected to the buffer reel via a belt. This has the advantage that the speed of the buffer reel can be adapted to the infeed speed of the filament via its own electric drive, independently of the transport reel.
Eine nach dieser technischen Lehre ausgebildete Pufferspule zur Anbringung an einem manuellen Mehrfachspulenschrank umfasst einen Spulenkern, eine Spulenwand, eine Seitenwand und eine Fangvorrichtung zum Einfangen des Filamentes, wobei der Spulenkern zum Mehrfachspulenschrank hin von der Seitenwand begrenzt wird, während der Spulenkern zu der Transportspule hin von der Spulenwand begrenzt wird. Der Spulenkern selbst ist so dimensioniert, dass hier die Filamente von 30 bis 80 Transportspulenwechseln aufgenommen werden können, dass heißt, der Spulenkern ist deutlich kürzer als der vergleichbare Spulenkern der Transportspule.A buffer spool designed according to this technical teaching for attachment to a manual multiple spool cabinet comprises a spool core, a spool wall, a side wall and a catching device for capturing the filament, the spool core being limited to the multiple spool cabinet by the side wall, while the spool core is limited to the transport spool by the coil wall is limited. The bobbin itself is dimensioned so that the filaments can be picked up from 30 to 80 transport bobbin changes, that is, the bobbin is significantly shorter than the comparable bobbin of the transport bobbin.
Die Fangvorrichtung unterstützt das Wechseln des Filamentes von der Transportspule auf die Pufferspule und weist vorteilhafterweise eine umlaufende Fangfläche auf, die sich radial an die Spulenwand und/oder die Seitenwand anschließt, wobei die Fangfläche ein auftreffendes Filament zum Spulenkern hin führt.The catching device supports the change of the filament from the transport reel to the buffer reel and advantageously has a circumferential catching surface that radially adjoins the bobbin wall and / or the side wall, the catching surface leading an impinging filament to the coil core.
In einer bevorzugten Weiterbildung schließt sich sowohl radial an die Seitenwand, als auch radial an die Spulenwand eine solche Fangfläche zum Einfangen des Filamentes an. Es hat sich als vorteilhaft erwiesen, die Seitenwand mit der dazugehörigen Fangfläche größer auszubilden, als die Spulenwand mit der dazugehörigen Fangfläche, weil durch die kleinere Fangfläche an der Spulenwand ein leichteres Überführen des Filamentes möglich ist, während die etwas größere Fangfläche an der Seitenwand das Filament zuverlässig fängt.In a preferred development, such a catching surface for catching the filament adjoins both the side wall and the spool wall radially. It has been shown to be beneficial to that Make the side wall with the associated catching surface larger than the coil wall with the associated catching surface, because the smaller catching surface on the coil wall makes it easier to transfer the filament, while the slightly larger catching surface on the side wall reliably catches the filament.
Diese Fangfläche ist vorteilhafterweise nicht exakt radial ausgerichtet, sondern geneigt ausgerichtet, insbesondere vom Spulenkern wegweisend geneigt, ausgerichtet. Dies hat den Vorteil, dass sich hierdurch der für das Filament maßgebliche Eingangsbereich vergrößert. Ein weiterer Vorteil besteht darin, dass die geneigte Fangfläche ein darauf auftreffendes Filament zum Spulenkern hin führt. Vorteilhafterweise beträgt der Winkel der Fangfläche zur Längsachse der Hauptwickelwelle zwischen 20° und 45°, vorzugsweise 30°.This catching surface is advantageously not aligned exactly radially, but aligned inclined, in particular aligned inclined away from the coil core. This has the advantage that it enlarges the entry area relevant for the filament. Another advantage is that the inclined catching surface guides a filament that strikes it towards the spool core. The angle of the catching surface to the longitudinal axis of the main winding shaft is advantageously between 20 ° and 45 °, preferably 30 °.
In einer bevorzugten Ausführungsform reicht die Fangvorrichtung, insbesondere ein radial äußerer Rand der Fangvorrichtung, bis über einen Teil der Transportspule, insbesondere bis über die Transportspulenseitenwand. Hierdurch wird das Überführen des Filamentes von der rotierenden Transportspule auf die rotierende Pufferspule erleichtert, weil ein versehentliches Abgleiten des Filamentes während der Übertragung in einen Bereich zwischen Transportspule und Pufferspule hierdurch zuverlässig vermieden wird. Vielmehr gelangt das Filament auf die ausladende Fangfläche und wird von dieser zum Spulenkern der Pufferspule hin weitergeführt.In a preferred embodiment, the safety device, in particular a radially outer edge of the safety device, extends over a part of the transport reel, in particular over the transport reel side wall. This facilitates the transfer of the filament from the rotating transport reel to the rotating buffer reel, because this reliably prevents the filament from accidentally sliding off during the transfer into an area between the transport reel and the buffer reel. Rather, the filament arrives at the projecting catching surface and is continued by this to the core of the buffer coil.
In einer weiteren, bevorzugten Ausführungsform ist an der Fangvorrichtung, insbesondere am radial äußeren Rand der Fangvorrichtung, eine umlaufende Sicherheitsschulter ausgebildet, die vorzugsweise als gekanteter oder gerändelter Rand der Fangvorrichtung ausgebildet ist. Insbesondere wenn diese Sicherheitsschulter als umlaufende Verdickung ausgebildet ist, hat dies den Vorteil, dass hiermit ein scharfkantiger Abschluss der Fangvorrichtung vermieden wird, sodass zum Einen der Bediener sich nicht verletzen kann und zum Anderen, dass das Filament nicht versehentlich beim Wechsel von der Transportspule zur Pufferspule durchtrennt wird.In a further, preferred embodiment, a circumferential safety shoulder is formed on the safety device, in particular on the radially outer edge of the safety device, which is preferably designed as an edged or knurled edge of the safety device. In particular, if this safety shoulder is designed as a circumferential thickening, this has the advantage that it is a sharp-edged end of the safety device is avoided, so that on the one hand the operator cannot injure himself and on the other hand that the filament is not accidentally cut when changing from the transport reel to the buffer reel.
Auch hat es sich als vorteilhaft erwiesen, die Sicherheitsschulter soweit um die Fangfläche zu bördeln, dass zwischen der Sicherheitsschulter und der Fangfläche eine umlaufende Ringnut entsteht. Dies hat den Vorteil, dass ein einmal auf der Fangfläche befindliches Filament nicht versehentlich aus der Fangfläche und der Pufferspule herausrutschen kann, sondern sich in diesem Falle in der umlaufenden Ringnut verfängt.It has also proven to be advantageous to bead the safety shoulder around the catch surface to such an extent that a circumferential ring groove is created between the safety shoulder and the catch surface. This has the advantage that once a filament is on the catching surface it cannot accidentally slip out of the catching surface and the buffer reel, but in this case get caught in the circumferential annular groove.
In einer alternativen Ausführungsform ist die Seitenwand und/oder die Spulenwand komplett geneigt ausgebildet und bildet somit gleichzeitig die Fangfläche der Fangvorrichtung. Mit anderen Worten ausgedrückt: In dieser Ausführungsform reicht die vom Spulenkern weggeneigte Fangvorrichtung bis zum Spulenkern, sodass die eigentliche Seitenwand entbehrlich ist. Dies vereinfacht die Herstellung einer solchen Spule.In an alternative embodiment, the side wall and / or the coil wall is designed to be completely inclined and thus simultaneously forms the catching surface of the catching device. In other words: In this embodiment, the safety gear inclined away from the coil core extends to the coil core, so that the actual side wall can be dispensed with. This simplifies the manufacture of such a coil.
In einer anderen, bevorzugten Ausführungsform ist der Spulenkern zur Transportspule hin konisch verjüngend ausgebildet. Dies hat den Vorteil, dass sich die auf dem Spulenkern ansammelnden Filamente am tiefsten Punkt des Spulenkerns sammeln und somit ein Verheddern oder ein versehentliches Lösen der in der Spule befindlichen Filamente vermieden wird.In another, preferred embodiment, the coil core is designed to taper conically towards the transport coil. This has the advantage that the filaments accumulating on the spool core collect at the lowest point of the spool core, thus avoiding tangling or accidental loosening of the filaments located in the spool.
