Abstract

The upcoiler has a winding shaft (10) which is rolled up with parallel strips. A comb shaft (16) is extended in a direction parallel to the winding shaft. Sleeves (18) are located on the comb shaft for carrying a separating wheel (20) for lateral guidance of the strips. The sleeves are fixed with a radially expandable clamping unit (24) that is extended on the periphery of the comb shaft along a longitudinal direction and individually adjusted in longitudinal positions of the comb shaft. An independent claim is included for the longitudinal cutting machine.

Description

Die Erfindung betrifft einen Aufwickler für in der Form paralleler Streifen von einer Längsschneidvorrichtung zugeführtes Bahnmaterial, mit einer Wickelwelle, auf welche die Streifen aufzuwickeln sind, und einer parallel zur der Wickelwelle verlaufenden Kammwelle, auf der Hülsen angeordnet sind, die jeweils eine Separierscheibe zur Seitenführung der Streifen tragen.The invention relates to a rewinder for in the form of parallel strips fed by a longitudinal cutting device web material, with a winding shaft, on which the strips are to be wound, and a parallel to the winding shaft extending comb shaft, are arranged on the sleeves, each having a Separierscheibe for lateral guidance of Wear stripes.

Bahnmaterial, das beispielsweise zur Ummantelung von Profilen oder zur Beschichtung von Kanten von Möbelplatten und dergleichen dient, wird häufig in der Form eines verhältnismäßig breiten Endlosbandes bereitgestellt und dann mit einer Längsschneidvorrichtung in schmalere streifen in der jeweils benötigten Breite aufgeteilt. Die Streifen werden dann auf der Wickelwelle zu dicht nebeneinander liegenden Wickeln aufgewickelt. Wenn die Streifen eine verhältnismäßig große Breite haben, so dass der Wickel auch bei größerem Durchmesser noch stabil bleibt, ist es möglich, zwei parallele Wickelwellen zu verwenden, auf die die Streifen in abwechselnder Folge aufgewickelt werden, so dass die auf derselben Wickelwelle gebildeten Wickel in Abstand zueinander angeordnet sind. Ansonsten werden alle Streifen auf dieselbe Wickelwelle aufgewickelt, so dass die aufeinanderfolgenden Wickel einander nahezu berühren. Insbesondere in diesem letzten Fall dient die Kammwelle mit ihren Separierscheiben dazu, den Streifen im Bereich des Umfangs des Wickels seitliche Führung zu geben, so dass die einzelnen Wickel voneinander getrennt bleiben. Die Abstände zwischen den Separierscheiben entsprechen dann den jeweiligen Streifenbreiten.Web material, which serves for example for covering profiles or for coating edges of furniture panels and the like, is often provided in the form of a relatively wide endless belt and then divided with a longitudinal cutting device into narrower strips in the respectively required width. The strips are then wound on the winding shaft to closely adjacent coils. If the strips have a relatively large width, so that the winding remains stable even with a larger diameter, it is possible to use two parallel winding shafts, on which the strips are wound in an alternating sequence, so that the winding formed on the same winding shaft in Distance from each other are arranged. Otherwise, all the strips are wound on the same winding shaft so that the successive coils almost touch each other. Especially in this last case, the comb shaft with its separating discs serves to give the strip in the region of the circumference of the coil lateral guidance, so that the individual coils remain separated from each other. The distances between the separating discs then correspond to the respective strip widths.

Bei herkömmlichen Aufwicklern entspricht die Länge jeder Hülse der Breite des zugehörigen Streifens, so dass die Hülsen als Abstandshalter dienen, mit denen die Abstände zwischen den Separierscheiben festgelegt werden. Wenn die Längsschneidvorrichtung auf andere Streifenbreiten umgerüstet wird, muss auch der Aufwickler entsprechend umgerüstet werden. Dazu werden die Hülsen auf der Kammwelle gegen einen Satz von Hülsen mit anderer Länge ausgetauscht.In conventional rewinders, the length of each sleeve corresponds to the width of the associated strip, so that the sleeves serve as spacers with which the distances between the separating discs are determined. If the slitter is converted to other strip widths, the rewinder must also be adjusted accordingly to be converted. For this purpose, the sleeves are replaced on the comb shaft against a set of sleeves of a different length.

Aufgabe der Erfindung ist es, einen Aufwickler zu schaffen, der sich einfacher auf andere Streifenbreiten umrüsten lässt.The object of the invention is to provide a rewinder that can be easily converted to other strip widths.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Hülsen mit mindestens einem in Längsrichtung am Umfang der Kammwelle verlaufenden, radial expandierbaren Spannorgan in einzeln einstellbaren Längspositionen auf der Kammwelle fixierbar sind.This object is achieved in that the sleeves are fixed with at least one extending in the longitudinal direction on the circumference of the comb shaft, radially expandable clamping member in individually adjustable longitudinal positions on the comb shaft.

Bei dem erfindungsgemäßen Aufwickler ist die Länge der Hülsen kleiner als die kleinste zu erwartende Streifenbreite, so dass zwischen den aufeinanderfolgenden Hülsen auf der Kammwelle im allgemeinen gewisse Zwischenräume bestehen, die es erlauben, die Längspositionen der Hülsen zu variieren und so an die jeweilige Streifenbreite anzupassen, ohne dass sämtliche Hülsen von der Kammwelle abgezogen und durch Hülsen anderer Länge ersetzt werden müssen. Dadurch wird nicht nur der Umrüstprozess vereinfacht, sondern es entfällt auch die Notwendigkeit, zahlreiche Sätze von Separierscheiben tragenden Hülsen mit jeweils unterschiedlichen Längen vorrätig zu halten.In the rewinder according to the invention, the length of the sleeves is smaller than the smallest expected strip width, so that between the successive sleeves on the comb shaft there are generally certain gaps, which allow to vary the longitudinal positions of the sleeves and thus adapt to the respective strip width, without having to pull off all the sleeves from the comb shaft and replace them with sleeves of different lengths. Not only does this simplify the retrofit process, it also eliminates the need to stock numerous sets of separators-carrying sleeves, each with different lengths.

Wenn alle Hülsen und damit alle Separierscheiben auf die gewünschten Positionen eingestellt sind, lassen sich mit Hilfe des Spannorgans sämtliche Hülsen in der eingestellten Position auf der Kammwelle fixieren.When all sleeves and thus all separating discs are set to the desired positions, all sleeves can be fixed in the set position on the comb shaft with the help of the tensioning element.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are specified in the subclaims.

Das Spannorgan kann durch einen pneumatisch expandierbaren Balg gebildet werden, der in einer in der Umfangsfläche der Kammwelle gebildeten Nut untergebracht ist.The tension member may be formed by a pneumatically expandable bellows housed in a groove formed in the peripheral surface of the comb shaft.

Zum einfachen Einstellen der Abstände zwischen den Separierscheiben können Lehren in den benötigten Standardlängen verwendet werden, die bei der Positionierung der Hülsen vorübergehend als Abstandshalter zwischen den Separierscheiben eingefügt werden.For easy setting of the distances between the separating discs, it is possible to use gauges in the required standard lengths, which are used in the positioning of the Pockets are temporarily inserted as a spacer between the separating discs.

Es sind Längsschneidvorrichtungen bekannt, bei denen die Messer und Gegenmesser als Tellermesser ausgebildet sind, die auf den jeweiligen Messerwellen sitzen und ebenfalls pneumatisch in den benötigten Positionen auf der Welle festgespannt werden. Ebenso sind numerisch gesteuerte Roboter bekannt, mit denen die Tellermesser automatisch positioniert werden können. Gemäß einer Weiterbildung der Erfindung wird dieser Roboter auch zur Positionierung der Separierscheiben benutzt. Das kann beispielsweise in der Form geschehen, dass der Roboter aus einer Position in der Nähe der Messerwellen in eine Position in der Nähe der Kammwelle gefahren wird, so dass er die Separierscheiben in ähnlicher Weise positionieren kann wie die Tellermesser. In einer bevorzugten Ausführungsform bleibt jedoch der Roboter stets in einer den Messerwellen benachbarten Position, und er weist einen Positionszeiger auf, der die Sollpositionen für die Separierscheiben angibt, so dass die Separierscheiben dann von Hand auf diese Sollpositionen eingestellt werden können. Der Positionszeiger kann beispielsweise durch einen auf dem Roboter montierten Laser gebildet werden.There are longitudinal cutting devices are known in which the knives and counter knives are designed as a disc knife, sitting on the respective blade shafts and are also tightened pneumatically in the required positions on the shaft. Similarly, numerically controlled robots are known with which the plate knives can be positioned automatically. According to one embodiment of the invention, this robot is also used for positioning the Separierscheiben. This can for example be done in the form that the robot is moved from a position in the vicinity of the knife shafts in a position near the comb shaft, so that he can position the separating discs in a similar manner as the disc knife. In a preferred embodiment, however, the robot always remains in a position adjacent to the cutter shafts, and it has a position indicator which indicates the desired positions for the separating wheels, so that the separating wheels can then be manually adjusted to these desired positions. The position indicator can be formed, for example, by a laser mounted on the robot.

Im folgenden werden Ausführungsbeispiele der Erfindung anhand der Zeichnung näher erläutert.In the following, embodiments of the invention will be explained in more detail with reference to the drawing.

Der in Fig. 1 gezeigte Aufwickler weist eine Wickelwelle 10 auf, auf die mehrere Streifen eines Bahnmaterials aufzuwickeln sind. Zu diesem Zweck werden Wickelkerne 12, beispielsweise in der Form von Papphülsen, deren Länge der Breite der aufzuwickelnden Streifen entspricht, in geeigneten Positionen auf der Wickelwelle 10 angeordnet und fixiert. Mit einem Klebeband wird dann ein Ende jedes Streifens auf die Umfangsfläche eines der Wickelkerne 12 aufgeklebt. Mit Hilfe eines nicht gezeigten Drehantriebs wird die Wickelwelle 10 in Drehung versetzt, so dass die Streifen zu Wickeln 14 aufgewickelt werden. Ein einzelner Wickel 14 ist in Fig. 1 strichpunktiert angedeutet.The in Fig. 1 shown rewinder has a winding shaft 10, are to be wound on a plurality of strips of a web material. For this purpose, winding cores 12, for example in the form of paperboard sleeves whose length corresponds to the width of the strips to be wound, are arranged and fixed in suitable positions on the winding shaft 10. With an adhesive tape, one end of each strip is then glued to the peripheral surface of one of the hubs 12. With the aid of a rotary drive, not shown, the winding shaft 10 is rotated, so that the strips are wound into coils 14. A single coil 14 is in Fig. 1 indicated by dash-dotted lines.

Parallel zu der Wickelwelle 10 ist eine Kammwelle 16 angeordnet, die mehrere Hülsen 18 trägt. Jede Hülse 18 trägt an einem Ende eine verhältnismäßige dünne Separierscheibe 20.Parallel to the winding shaft 10, a comb shaft 16 is arranged, which carries a plurality of sleeves 18. Each sleeve 18 carries at one end a relatively thin separating disk 20.

Während des Betriebs des Aufwicklers wird die Kammwelle 16 in den Richtungen rechtwinklig zu ihrer Längsachse so relativ zu der Wickelwelle 10 positioniert, dass die Separierscheiben 20 kammförmig zwischen die einzelnen Streifen greifen, die auf die Wickelwelle 10 aufzuwickeln sind. Dadurch werden die einzelnen Streifen beim Aufwickeln in seitlicher Richtung so geführt, dass sie gerade und sauber voneinander getrennte Wickel 14 bilden und nicht etwa ein Streifen von einem Wickel auf den benachbarten Wickel überläuft. Die Kammwelle 16 kann in den Richtungen rechtwinklig zu ihrer Längsachse in der Weise automatisch verstellbar sein, dass sie sich dem allmählich zunehmenden Durchmesser der Wickel 14 anpasst, so dass die Separierscheiben 20 stets im Bereich des äußeren Umfangs der Wickel bleiben. Außerdem kann die Kammwelle 16 passiv drehbar sein, so dass die Reibung zwischen den Separierscheiben 20 und den Wickeln 14 minimiert wird.During operation of the rewinder, the comb shaft 16 is positioned in the directions perpendicular to its longitudinal axis relative to the winding shaft 10 such that the separating disks 20 are combed between the individual strips to be wound on the winding shaft 10. As a result, the individual strips are guided during winding in the lateral direction so that they form straight and clean separate from each other 14 rolls and not overflows a strip of a roll on the adjacent winding. The comb shaft 16 may be automatically adjustable in the directions perpendicular to its longitudinal axis in such a way that it adapts to the gradually increasing diameter of the winding 14, so that the Separierscheiben 20 always remain in the region of the outer circumference of the winding. In addition, the comb shaft 16 may be passively rotatable, so that the friction between the Separierscheiben 20 and the coils 14 is minimized.

Eine Besonderheit des hier gezeigten Aufwicklers besteht darin, dass die Länge der Hülsen 18 nicht größer ist als die kleinste in Frage kommende Breite der aufzuwickelnden Streifen. Da die Abstände zwischen den Separierscheiben 20 jedoch der jeweiligen Streifenbreite entsprechen, bedeutet dies, dass zwischen den Enden der aufeinanderfolgenden Hülsen 18 im Normalfall gewisse Zwischenräume 22 verbleiben.A peculiarity of the winder shown here is that the length of the sleeves 18 is not greater than the smallest candidate width of the wound strip. However, since the distances between the Separierscheiben 20 correspond to the respective strip width, this means that between the ends of the successive sleeves 18 in the normal case certain gaps 22 remain.

Damit die Hülsen 18 nicht in Längsrichtung auf der Kammwelle 16 verrutschen, weist die Kammwelle mindestens an einer Stelle ihres Umfangs ein radial expandierbares Spannorgan 24 auf, das sich über die Positionen sämtlicher Hülsen 18 erstreckt.Thus, the sleeves 18 do not slip in the longitudinal direction on the comb shaft 16, the comb shaft at least at one point of its circumference on a radially expandable clamping member 24, which extends over the positions of all the sleeves 18.

Wie Fig. 2 zeigt, wird das Spannorgan 24 in diesem Beispiel durch einen pneumatisch aufblasbaren Balg oder Schlauch aus gummielastischem Material gebildet, der in einer Längsnut 26 der Kammwelle 16 untergebracht und über radiale Bohrungen 28 mit einer zentralen Axialbohrung 30 der Kammwelle verbunden ist.As Fig. 2 shows, the clamping member 24 is formed in this example by a pneumatically inflatable bellows or hose made of rubber-elastic material, which is housed in a longitudinal groove 26 of the comb shaft 16 and connected via radial bores 28 with a central axial bore 30 of the comb shaft.

Wie Fig. 1 zeigt, weist die Kammwelle 16 an einem Ende einen Druckluftanschluss 32 auf, der an eine Druckluftquelle ankuppelbar ist, um das Spannorgan 24 zu expandieren, so dass es sich gegen die inneren Umfangsflächen der Hülsen 18 legt, um diese auf der Kammwelle 16 festzuspannen. Der Druckluftanschluss 32 kann ein von Hand zu öffnendes Rückschlagventil enthalten, das den Druck im Spannorgan 24 hält, wenn die Druckluftquelle abgekuppelt wird. Wenn die Positionen der Hülsen 18 verstellt werden sollen, wird das Rückschlagventil geöffnet, so dass das Spannglied 24 kollabiert.As Fig. 1 shows, the comb shaft 16 at one end to a compressed air port 32 which can be coupled to a source of compressed air to expand the clamping member 24 so that it rests against the inner peripheral surfaces of the sleeves 18 to clamp this on the comb shaft 16. The compressed air port 32 may include a manually openable check valve which maintains the pressure in the clamping member 24 when the compressed air source is disconnected. When the positions of the sleeves 18 are to be adjusted, the check valve is opened so that the tendon 24 collapses.

In einer anderen Ausführungsform kann die Druckluftquelle auch über eine Drehdurchführung an die Axialbohrung 30 der Kammwelle angekuppelt sein.In another embodiment, the compressed air source can also be coupled via a rotary feedthrough to the axial bore 30 of the comb shaft.

In Fig. 3 ist eine Längsschneidanlage schematisch in einer Draufsicht gezeigt. Zu dieser Längsschneidanlage gehören eine Längsschneidvorrichtung 34 sowie der in Fig. 1 gezeigte Aufwickler, von dem in Fig. 3 aus Gründen der Übersichtlichkeit nur die Kammwelle 16 dargestellt ist.In Fig. 3 a longitudinal cutting system is shown schematically in a plan view. To this longitudinal cutting system include a longitudinal cutting device 34 and the in Fig. 1 shown rewinder, of which in Fig. 3 for clarity, only the comb shaft 16 is shown.

Die Längsschneidvorrichtung 34 weist eine Messerwelle 36 auf, die parallel zu der Kammwelle 16 verläuft und mit Tellermessern 38 bestückt ist. Eine weitere, mit Gegenmessem bestückte Messerwelle liegt in Fig. 3 unsichtbar hinter der gezeigten Messerwelle 36.The longitudinal cutting device 34 has a knife shaft 36, which runs parallel to the comb shaft 16 and is equipped with plate knives 38. Another, equipped with counter knives knife shaft lies in Fig. 3 invisible behind the knife shaft 36 shown.

Außerdem gehört zu der Längsschneidvorrichtung 34 ein Roboter 40, der dazu dient, die Tellermesser 38 auf den Messerwellen zu positionieren. Die Messerwellen 36 weisen jeweils ein radial expandierbares Spannorgan auf, mit dem die Tellermesser 38 in der jeweils eingestellten Axialposition auf der Welle fixiert werden können. Nach Lösen dieses Spannorgans können die Tellermesser mit Hilfe des Roboters 40 auf der Messerwelle 36 verschoben werden. Dazu weist der Roboter 40 eine parallel zu den Messerwellen 36 verlaufende Führungsschiene 42 auf, auf der ein Wagen 44 mit Hilfe eines numerisch gesteuerten Antriebs verfahrbar ist. Der Wagen 44 weist einen die Messerwellen 36 übergreifenden Ausleger 46 auf, der nicht näher gezeigte, ausfahrbare und zurückziehbare Werkzeuge zum Verschieben der Tellermesser 38 trägt.In addition, the longitudinal cutting device 34 includes a robot 40 which serves to position the knife blades 38 on the cutter shafts. The knife shafts 36 each have a radially expandable clamping member with which the knife blades 38 can be fixed in the respective set axial position on the shaft. After releasing this clamping member, the knife blades can be moved by means of the robot 40 on the blade shaft 36. For this purpose, the robot 40 has a guide rail 42 running parallel to the cutter shafts 36, on which a carriage 44 can be moved by means of a numerically controlled drive. The carriage 44 has a knife shafts 36 cross-arm 42 which carries not shown in detail, extendable and retractable tools for moving the knife blades 38.

Während eines Längsschneidvorgangs wird ein Band 48 des zu schneidenden Bahnmaterials von rechts in Fig. 3 zu der Schneidvorrichtung 34 zugeführt und mit Hilfe der Tellermesser 38 in einzelne Streifen 50 aufgeteilt, die weiter zu dem Aufwickler laufen, wo sie durch die Separierscheiben 20 der Kammwelle 16 geführt und schließlich auf die Wickelwelle 10 aufgewickelt werden.During a longitudinal cutting operation, a band 48 of the web material to be cut is inserted from the right in FIG Fig. 3 supplied to the cutting device 34 and divided by means of the disc knife 38 into individual strips 50, which continue to run to the rewinder, where they are guided by the separating discs 20 of the comb shaft 16 and finally wound onto the winding shaft 10.

Da die Separierscheiben 20 notwendig eine gewisse Dicke aufweisen müssen (die in der Zeichnung übertrieben dargestellt ist), laufen die Streifen 50 auf der Strecke zwischen der Längsschneidvorrichtung 34 und dem Aufwickler fächerförmig auseinander. Der Abstand zwischen der Längsschneidvorrichtung und dem Aufwickler ist so bemessen, dass die dadurch bedingte seitliche Auslenkung der Streifen 50 so klein bleibt, dass die Streifen nicht reißen.Since the separating wheels 20 must necessarily have a certain thickness (which is exaggerated in the drawing), the strips 50 fan out in the distance between the slitter 34 and the winder. The distance between the slitter and the winder is such that the consequent lateral deflection of the strips 50 remains so small that the strips do not tear.

Wenn die Anlage für einen neuen Schneidvorgang eingerichtet werden soll, so werden die gewünschten Streifenbreiten in die numerische Steuerung des Roboters 40 eingegeben. Für verschiedene Streifen 50 können dabei auch unterschiedliche Breiten eingegeben werden. Die Spannorgane der Messerwellen 36 werden gelöst, und der Wagen 44 fährt längs der Führungsschiene 42 in die durch die numerische Steuerung vorgegebenen Positionen, um mit seinem Ausleger 46 die einzelnen Tellermesser 38 entsprechend den einprogrammierten Streifenbreiten zu positionieren. Die Tellermesser werden dann in den eingestellten Positionen festgespannt, und der Wagen 40 fährt wieder in seine Ruheposition.When the equipment is to be set up for a new cutting operation, the desired strip widths are entered into the numerical control of the robot 40. For different strips 50 different widths can be entered. The clamping members of the knife shafts 36 are released, and the carriage 44 travels along the guide rail 42 to the predetermined positions by the numerical control to position, with its jib 46, the individual jaw knives 38 in accordance with the programmed-in strip widths. The plate knives are then tightened in the set positions, and the carriage 40 moves back to its rest position.

Um auch die Separierscheiben 20 der Kammwelle 16 zu positionieren, wird das Spannorgan 24 gelöst, und die Hülsen 18 werden von Hand positioniert. Dazu kann als Hilfsmittel eine Lehre 52 verwendet werden, die die Sollabstände zwischen den benachbarten Separierscheiben 20 vorgibt.In order to also position the Separierscheiben 20 of the comb shaft 16, the clamping member 24 is released, and the sleeves 18 are positioned by hand. For this purpose, a gauge 52 can be used as an aid, which specifies the desired spacing between the adjacent separating discs 20.

Schließlich werden die Hülsen 18 mit Hilfe des Spannorgans 24 in den eingestellten Positionen fixiert. Das Band 48 wird in die Schneidvorrichtung 34 eingefädelt, und die Schneidvorrichtung wird kurzzeitig in Betrieb genommen, um die Streifen 50 bis zu einer Länge zu schneiden, die ausreicht, die freien Enden dieser Streifen an die Wickelkerne 12 der Wickelwelle 10 anzukleben. Danach werden die Schneidvorrichtung 34 und der Aufwickler in Betrieb gesetzt, so dass das Band 48 fortlaufend in die Streifen 50 geschnitten wird, die dann auf der Wickelwelle 10 aufgewickelt werden.Finally, the sleeves 18 are fixed by means of the clamping member 24 in the adjusted positions. The belt 48 is threaded into the cutter 34 and the cutter is briefly put into operation to cut the strips 50 to a length sufficient to adhere the free ends of these strips to the hubs 12 of the winding shaft 10. Thereafter, the cutter 34 and the rewinder are put into operation, so that the tape 48 is continuously cut into the strips 50, which are then wound on the winding shaft 10.

Fig. 4 zeigt eine Längsschneidanlage gemäß einem anderen Ausführungsbeispiel in einem Zustand, in dem während der Rüstphase die Hülsen 18 auf der Kammwelle 16 positioniert werden. Bei dieser Ausführungsform ist auf dem Wagen 44 ein Laser 54 montiert, dessen Laserstrahl 56 exakt rechtwinklig zu den Achsen der Messerwellen 36 und der Kammwelle 16 orientiert und auf die Kammwelle 16 gerichtet ist. Der Laserstrahl 56 bildet so einen Positionszeiger in der Form eines Lichtpunktes, der angibt, wie die Hülsen 18 auf der Kammwelle 16 zu positionieren sind. Beispielsweise markiert der Lichtpunkt die Position, auf die das von der Separierscheibe 20 abgewandte Ende der Hülse 18 eingestellt werden soll. Fig. 4 shows a longitudinal cutting machine according to another embodiment in a state in which the sleeves 18 are positioned on the comb shaft 16 during the setup phase. In this embodiment, a laser 54 is mounted on the carriage 44, the laser beam 56 is oriented exactly at right angles to the axes of the cutter shafts 36 and the comb shaft 16 and directed to the comb shaft 16. The laser beam 56 thus forms a position indicator in the form of a light spot, which indicates how the sleeves 18 are to be positioned on the comb shaft 16. For example, the marked Light point the position to which the remote from the separating wheel 20 end of the sleeve 18 is to be adjusted.

Die numerische Steuerung des Roboters 40 berechnet anhand der zuvor eingegebenen und gespeicherten Positionen der Tellermesser 38 automatisch die Sollpositionen für die Separierscheiben 20, unter Berücksichtigung der in Fig. 3 gezeigten Auffächerung der Streifen 50. Der Wagen 44 wird dann schrittweise so verfahren, dass der Laserstrahl 56 nacheinander die Sollpositionen der einzelnen Hülsen 18 anzeigt. In dem in Fig. 4 gezeigten Zustand ist eine Hülse 18 (am in Fig. 4 unteren Ende der Kammwelle 16) bereits auf die Sollposition eingestellt worden, während die meisten übrigen Hülsen sich noch platzsparend zusammengeschoben am entgegengesetzten Ende der Spannwelle befinden. Eine Hülse wird gerade in die strichpunktiert eingezeichnete Sollposition verschoben.The numerical control of the robot 40 automatically calculates the target positions for the separating discs 20 based on the previously inputted and stored positions of the disc knives 38, taking into account the in Fig. 3 Fanning the strips 50. The carriage 44 is then moved stepwise so that the laser beam 56 successively indicates the desired positions of the individual sleeves 18. In the in Fig. 4 shown state is a sleeve 18 (at in Fig. 4 lower end of the comb shaft 16) has already been set to the desired position, while most of the remaining sleeves are still pushed together to save space at the opposite end of the clamping shaft. A sleeve is just moved to the dot-dashed set position.

Das durch einen Balg oder Schlauch gebildete Spannorgan 24 der Kammwelle 16 kann so konfiguriert sein, dass es auch im nicht expandierten Zustand geringfügig aus der Längsnut 26 heraus ragt und so der Verschiebung der Hülsen 18 einen gewissen Reibungswiderstand entgegensetzt, der gerade groß genug ist, die Hülsen in der eingestellten Position zu halten, bis sie durch Expandieren des Spannorgans endgültig fixiert werden.The clamping member 24 formed by a bellows or tube of the comb shaft 16 may be configured so that it protrudes slightly out of the longitudinal groove 26 even in the unexpanded state and so the displacement of the sleeves 18 opposes a certain frictional resistance, which is just large enough Keep sleeves in the set position until they are finally fixed by expanding the clamping device.

Der Laser 54 oder ein nicht gezeigter gesonderter Laser können dazu benutzt werden, in entsprechender Weise auch die Positionen der Wickelkerne 12 auf der Wickelwelle 10 einzustellen.The laser 54 or a separate laser, not shown, can be used to adjust the positions of the winding cores 12 on the winding shaft 10 in a corresponding manner.
