Definitions
- the invention relates to a yarn tensioning device having an inlet guide, an outlet guide and therebetween a thread drum having an axis of rotation and a working area on which extends in the circumferential direction a yarn path between the inlet guide and the outlet guide.
- Such a thread tensioning device is for example off DE 43 24 412 A1 known. It serves to provide a thread, which is withdrawn from a spool arranged in a gate, with a tension which is desired for a subsequent further processing of the thread.
- the thread drum for example, braked or at a different speed than the thread be driven. If a thread passes through the thread path, then it is in the work area on the thread drum and is braked or accelerated accordingly, so that sets the desired tension in the thread.
- Different threads usually have different properties as well. This can cause a thread drum that works well with one type of thread to fail with another type of thread. Accordingly, you can make the thread drum interchangeable. The operator will then use a matching thread drum depending on the type of thread used.
- a thread tensioning device is usually required for each spool position.
- a gate can have several hundred coil positions. For example, even if changing a thread drum requires only 15 seconds, a gate that has 800 spool positions requires 200 minutes, well over three hours.
- the invention has for its object to achieve high flexibility with little expenditure of time.
- This object is achieved in a yarn tensioning device of the type mentioned above in that the working area is divided in the axial direction into at least two sections having different properties.
- a first section has a smooth contact surface.
- the smooth contact surface is used on delicate threads, but with the smooth surface, they have sufficient frictional engagement.
- the frictional engagement can be enhanced by the yarn is passed around the thread drum with several turns.
- the smooth contact surface encloses an acute angle with the axis of rotation.
- the contact surface is thus formed in the form of a cone section. The thread path can then be guided so that individual turns of the thread do not cross each other.
- a second portion has a V-shaped groove.
- this V-shaped groove of the thread is inserted, so that the frictional engagement with the thread drum can be increased.
- the groove has at least one wall in which teeth and interdental spaces alternately are arranged.
- Such an arrangement is also referred to as "Criprad”.
- a crimping wheel has the advantage that you can achieve a good frictional engagement between the thread drum and the thread.
- dirt can settle out, for example residues of a finish, and that filaments can be pulled out with sensitive threads or yarns.
- the groove is formed between two plate members, wherein a plate member facing the first portion forms a boundary for the first portion toward the second portion.
- a plate member facing the first portion forms a boundary for the first portion toward the second portion.
- the inlet guide and / or the outlet guide are adjustable relative to the thread drum between a first position, which is associated with the first portion, and a second position, which is associated with the second portion, adjustable.
- the adjustment can consist both in that one adjusts the inlet guide and / or the outlet guide parallel to the axis of rotation and in that one adjusts the position of the thread drum parallel to the axis of rotation. It can thus be achieved that the thread at the inlet and / or the outlet of the respective section correctly is assigned. This keeps a load of the respective thread small.
- a Fadenleit worn is arranged with at least one movable thread guide.
- the yarn guide can be under the tension of a spring, for example.
- the thread guiding element can be used to change the force with which the thread wraps around the thread drum.
- the position of the thread guiding element and the thread drum is variable relative to one another in a direction parallel to the axis of rotation. Even when passing through the yarn guide then no impermissible stresses are applied to the thread. In addition to the thread guide alone, you can also adjust the entire Fadenleit Nur relative to the thread drum, where you can adjust either the thread drum or Fadenleit worn or both here.
- a calming device is arranged in the thread path behind the inlet guide, the position of which is adjustable relative to the thread drum in a direction parallel to the axis of rotation.
- a reassurance makes sense to achieve a uniform application of force to the thread when circulating around the thread drum. Due to the adjustability parallel to the axis of rotation can also be achieved here that the thread can pass through the thread tensioning device in a desired direction, preferably in a plane. If the thread is passed over the tapered smooth surface, however, the inlet and the outlet of the thread parallel to the rotation axis may be slightly apart.
- Fig. 1 shows a thread tensioning device 1 with a base 2, on which a thread drum 3 is rotatably mounted.
- the thread drum 3 can be rotatably connected to an electric motor 4, which can also be operated as a generator.
- an inlet guide 5 and an outlet guide 6 are arranged.
- a thread 7 is guided through the inlet guide 5, wraps around the thread drum 3 and is then guided through the outlet guide 6.
- a calming device 8 is arranged, which is formed by two conical plates 9, 10 which lie with their smaller diameter on each other.
- the reassurance 8 dampens vibrations in the thread 7, which could be caused by the withdrawal of the thread 7 overhead, for example, from a coil, not shown.
- a yarn guide 11 is arranged with a movable Fadenleitelement 12 which is movable in the direction of a double arrow 13, that is substantially transverse to the direction of the yarn 7.
- the yarn guide 12 can by a spring not shown under a certain bias can be set.
- the thread drum has a work area 14, which has a first portion 15 and a second portion 16.
- the first section 15 has a smooth contact surface for the thread 7. It is slightly conically inclined, i. the abutment surface includes an acute angle with a rotation axis 22 of the thread drum 3. At the end with the smaller diameter, a cover plate 17 is provided, which projects radially beyond the first portion 15. This prevents that the thread 7 can be removed via the head of the first section 15.
- the second section 16 has a V-shaped groove 18. How out Fig. 3 can be seen, the groove 18 at least one wall 19, in which teeth 20 and tooth spaces 21 are arranged alternately.
- the second section 16 is thus designed as a "crimping wheel" and has a relatively good frictional engagement with the thread 7 when the thread 7 is guided through the second section 16.
- the groove 18 is formed between two plates 23, 24.
- the first section 15 facing plate 23 has a slightly larger diameter than the first portion 15 in the region of the plate 23 so that the plate 23 forms a boundary for the first portion 15 in the direction of the second portion 16.
- the thread 7 can not accidentally slip out of the first section 15 in the second section 16 or vice versa.
- the thread drum 3 has on its side facing the base 2 an extension 30 with an opening 25 which can be plugged onto a shaft of the motor 4. By attaching the thread drum can be rotatably connected to the motor 4.
- the thread drum 3 may also have more than the two illustrated sections 15, 16. In many cases, however, you will get along with two different sections.

Abstract
Description
Die Erfindung betrifft eine Fadenspannvorrichtung mit einer Einlaufführung, einer Auslaufführung und dazwischen einer Fadentrommel, die eine Rotationsachse und einen Arbeitsbereich aufweist, auf dem in Umfangsrichtung ein Fadenpfad zwischen der Einlaufführung und der Auslaufführung verläuft.The invention relates to a yarn tensioning device having an inlet guide, an outlet guide and therebetween a thread drum having an axis of rotation and a working area on which extends in the circumferential direction a yarn path between the inlet guide and the outlet guide.
Eine derartige Fadenspannvorrichtung ist beispielsweise aus
Unterschiedliche Fäden haben in der Regel auch unterschiedliche Eigenschaften. Dies kann dazu führen, dass eine Fadentrommel, die mit einer Fadenart gut zusammenarbeitet, bei einer anderen Fadenart versagt. Dementsprechend kann man die Fadentrommel auswechselbar gestalten. Der Bediener wird dann in Abhängigkeit von der verwendeten Fadenart eine dazu passende Fadentrommel verwenden.Different threads usually have different properties as well. This can cause a thread drum that works well with one type of thread to fail with another type of thread. Accordingly, you can make the thread drum interchangeable. The operator will then use a matching thread drum depending on the type of thread used.
In einem Gatter ist in der Regel für jede Spulenposition eine Fadenspannvorrichtung erforderlich. Ein Gatter kann durchaus mehrere Hundert Spulenpositionen aufweisen. Auch wenn zum Wechsel einer Fadentrommel beispielsweise nur 15 Sekunden erforderlich sind, benötigt man bei einem Gatter, das 800 Spulenpositionen hat 200 Minuten, also deutlich über drei Stunden.In a gate, a thread tensioning device is usually required for each spool position. A gate can have several hundred coil positions. For example, even if changing a thread drum requires only 15 seconds, a gate that has 800 spool positions requires 200 minutes, well over three hours.
Der Erfindung liegt die Aufgabe zugrunde, eine hohe Flexibilität mit geringem Zeitaufwand zu erreichen.The invention has for its object to achieve high flexibility with little expenditure of time.
Diese Aufgabe wird bei einer Fadenspannvorrichtung der eingangs genannten Art dadurch gelöst, dass der Arbeitsbereich in Axialrichtung in mindestens zwei Abschnitte unterteilt ist, die unterschiedliche Eigenschaften aufweisen.This object is achieved in a yarn tensioning device of the type mentioned above in that the working area is divided in the axial direction into at least two sections having different properties.
Man kann dann mit einer Fadentrommel mehrere unterschiedliche Fadenarten behandeln. Die Bedienungsperson muss den Faden, der durch die Fadenspannvorrichtung geführt wird, nur auf dem richtigen Abschnitt des Arbeitsbereiches platzieren. Da bei einem Fadenwechsel eine Handhabung des Fadens ohnehin erforderlich ist, bedeutet die Anordnung des Fadens im richtigen Abschnitt in Axialrichtung praktisch keinen zusätzlichen Aufwand. Dennoch kann man mit der gleichen Fadenspannvorrichtung unterschiedliche Fadenarten behandeln.You can then handle a thread drum several different types of threads. The operator must place the thread passing through the thread tensioning device only on the correct portion of the work area. Since a thread change handling of the thread is required anyway, the arrangement of the thread in the correct section in the axial direction means virtually no additional effort. Nevertheless, you can treat different types of threads with the same thread tensioning device.
In einer bevorzugten Ausgestaltung weist ein erster Abschnitt eine glatte Anlagefläche auf. Die glatte Anlagefläche wird bei empfindlichen Fäden verwendet, die mit der glatten Fläche allerdings einen ausreichenden Reibeingriff haben. Gegebenenfalls kann der Reibeingriff verstärkt werden, indem der Faden mit mehreren Windungen um die Fadentrommel geführt wird.In a preferred embodiment, a first section has a smooth contact surface. The smooth contact surface is used on delicate threads, but with the smooth surface, they have sufficient frictional engagement. Optionally, the frictional engagement can be enhanced by the yarn is passed around the thread drum with several turns.
Hierbei ist bevorzugt, dass die glatte Anlagefläche einen spitzen Winkel mit der Rotationsachse einschließt. Die Anlagefläche ist also in Form eines Konusabschnitts ausgebildet. Der Fadenpfad kann dann so geführt werden, dass sich einzelne Windungen des Fadens nicht überkreuzen.It is preferred that the smooth contact surface encloses an acute angle with the axis of rotation. The contact surface is thus formed in the form of a cone section. The thread path can then be guided so that individual turns of the thread do not cross each other.
Vorzugsweise weist ein zweiter Abschnitt eine V-förmige Nut auf. In diese V-förmige Nut wird der Faden eingelegt, so dass der Reibschluss mit der Fadentrommel vergrößert werden kann.Preferably, a second portion has a V-shaped groove. In this V-shaped groove of the thread is inserted, so that the frictional engagement with the thread drum can be increased.
Hierbei ist bevorzugt, dass die Nut mindestens eine Wand aufweist, in der abwechselnd Zähne und Zahnzwischenräume angeordnet sind. Eine derartige Anordnung wird auch als "Criprad" bezeichnet. Ein Criprad hat den Vorteil, dass man einen guten Reibeingriff zwischen der Fadentrommel und dem Faden erreichen kann. Es hat aber den Nachteil, dass sich Schmutz absetzen kann, beispielsweise Reste einer Avivage, und dass bei empfindlichen Fäden oder Garnen Filamente herausgezogen werden können.In this case, it is preferred that the groove has at least one wall in which teeth and interdental spaces alternately are arranged. Such an arrangement is also referred to as "Criprad". A crimping wheel has the advantage that you can achieve a good frictional engagement between the thread drum and the thread. However, it has the disadvantage that dirt can settle out, for example residues of a finish, and that filaments can be pulled out with sensitive threads or yarns.
Vorzugsweise ist die Nut zwischen zwei Plattenelementen gebildet, wobei ein dem ersten Abschnitt zugewandtes Plattenelement eine Begrenzung für den ersten Abschnitt in Richtung auf den zweiten Abschnitt bildet. Man benötigt also keine zusätzlichen Elemente, um eine Abgrenzung zwischen den beiden Abschnitten zu erzeugen und damit zu verhindern, dass der Faden während des Betriebs vom ersten Abschnitt zum zweiten Abschnitt gelangt oder umgekehrt. Vielmehr wird die Grenze zwischen dem ersten Abschnitt und dem zweiten Abschnitt durch die Ausbildung des zweiten Abschnitts erzeugt.Preferably, the groove is formed between two plate members, wherein a plate member facing the first portion forms a boundary for the first portion toward the second portion. Thus, there is no need for additional elements to create a boundary between the two sections, thereby preventing the thread from passing from the first section to the second section during operation, or vice versa. Rather, the boundary between the first portion and the second portion is created by the formation of the second portion.
Vorzugsweise sind die Einlaufführung und/oder die Auslaufführung relativ zur Fadentrommel zwischen einer ersten Position, die dem ersten Abschnitt zugeordnet ist, und einer zweiten Position, die dem zweiten Abschnitt zugeordnet ist, verstellbar. Die Verstellung kann sowohl darin bestehen, dass man die Einlaufführung und/oder die Auslaufführung parallel zur Rotationsachse verstellt als auch darin, dass man die Position der Fadentrommel parallel zur Rotationsachse verstellt. Man kann damit erreichen, dass der Faden beim Einlauf und/oder beim Auslauf dem jeweiligen Abschnitt richtig zugeordnet wird. Dies hält eine Beanspruchung des jeweiligen Fadens klein.Preferably, the inlet guide and / or the outlet guide are adjustable relative to the thread drum between a first position, which is associated with the first portion, and a second position, which is associated with the second portion, adjustable. The adjustment can consist both in that one adjusts the inlet guide and / or the outlet guide parallel to the axis of rotation and in that one adjusts the position of the thread drum parallel to the axis of rotation. It can thus be achieved that the thread at the inlet and / or the outlet of the respective section correctly is assigned. This keeps a load of the respective thread small.
In einer bevorzugten Ausgestaltung ist vorgesehen, dass zwischen der Fadentrommel und der Einlaufführung und/oder der Auslaufführung eine Fadenleiteinrichtung mit mindestens einem beweglichen Fadenleitelement angeordnet ist. Das Fadenleitelement kann beispielsweise unter der Spannung einer Feder stehen. Mit dem Fadenleitelement kann unter anderem bewirkt werden, dass die Kraft, mit der der Faden die Fadentrommel umschlingt, verändert wird.In a preferred embodiment it is provided that between the thread drum and the inlet guide and / or the outlet guide a Fadenleiteinrichtung is arranged with at least one movable thread guide. The yarn guide can be under the tension of a spring, for example. Among other things, the thread guiding element can be used to change the force with which the thread wraps around the thread drum.
Hierbei ist bevorzugt, dass die Position des Fadenleitelements und der Fadentrommel relativ zueinander in eine Richtung parallel zur Rotationsachse veränderbar ist. Auch beim Durchlaufen des Fadenleitelements werden dann keine unzulässigen Spannungen auf den Faden aufgetragen. Neben dem Fadenleitelement alleine kann man auch die gesamte Fadenleiteinrichtung relativ zur Fadentrommel verstellen, wobei man auch hier entweder die Fadentrommel oder die Fadenleiteinrichtung oder beide verstellen kann.In this case, it is preferred that the position of the thread guiding element and the thread drum is variable relative to one another in a direction parallel to the axis of rotation. Even when passing through the yarn guide then no impermissible stresses are applied to the thread. In addition to the thread guide alone, you can also adjust the entire Fadenleiteinrichtung relative to the thread drum, where you can adjust either the thread drum or Fadenleiteinrichtung or both here.
Vorzugsweise ist im Fadenpfad hinter der Einlaufführung eine Beruhigungseinrichtung angeordnet, deren Position relativ zur Fadentrommel in einer Richtung parallel zur Rotationsachse verstellbar ist. Insbesondere dann, wenn der Faden über Kopf von der Spule abgezogen wird und sich ein "Ballon" ergibt, ist eine Beruhigungseinrichtung sinnvoll, um eine gleichmäßige Kraftbeaufschlagung des Fadens beim Umlauf um die Fadentrommel zu erreichen. Durch die Verstellbarkeit parallel zur Rotationsachse kann man auch hier erreichen, dass der Faden die Fadenspannvorrichtung in einer gewünschten Richtung, vorzugsweise in einer Ebene, durchlaufen kann. Wenn der Faden über die konisch geneigte glatte Fläche geführt wird, können allerdings der Einlauf und der Auslauf des Fadens parallel zur Rotationsachse etwas voneinander entfernt sein.Preferably, a calming device is arranged in the thread path behind the inlet guide, the position of which is adjustable relative to the thread drum in a direction parallel to the axis of rotation. In particular, when the thread is pulled off the head of the bobbin and results in a "balloon", a reassurance makes sense to achieve a uniform application of force to the thread when circulating around the thread drum. Due to the adjustability parallel to the axis of rotation can also be achieved here that the thread can pass through the thread tensioning device in a desired direction, preferably in a plane. If the thread is passed over the tapered smooth surface, however, the inlet and the outlet of the thread parallel to the rotation axis may be slightly apart.
