Description
Die Erfindung betrifft eine Vorrichtung zur Ueberwachung
des Fadenlaufs an einem Spulengatter,
insbesondere an einem Zettelgatter gemäss dem
Oberbegriff von Anspruch 1. Derartige Vorrichtungen
haben die Aufgabe, den vom Spulengatter
abgezogenen Fäden einerseits eine bestimmte Fadenspannung
zu vermitteln, anderseits aber auch
ein Nachlassen der Fadenspannung, z.B. bei Fadenbruch
zu ermitteln und bei dem dabei ausgelösten
Maschinenstillstand die Fäden festzuklemmen,
um ein Nachlaufen zu verhindern. Vergleichbare
Vorrichtungen wurden insbesondere bei V-förmigen
Zettelgattern eingesetzt, bei denen die Umlenkung
der Fäden in Richtung Wickelvorrichtung unmittelbar
an der Wächternadel erfolgt.The invention relates to a device for monitoring
the thread run on a creel,
especially on a slip gate according to the
Preamble of
Gattungsmässig vergleichbare Vorrichtungen sind beispielsweise in der US-A-4,598,184 oder in der EP-A-311 781 beschrieben. Bis anhin wurden dabei die Klemmvorrichtungen mit stets gleichbleibender Druckkraft beaufschlagt, wobei jede Fadenqualität mit der gleiche Klemmkraft festgeklemmt wurde. Bei der EP-A-311 781 ist zwar die Federvorrichtung mit einer zusätzlichen Steuerfeder versehen, die eine Entlastung der Klemmbacke erlaubt. Allerdings ist eine derartige Entlastung nur innerhalb einer ganzen vertikalen Reihe von Klemmvorrichtungen möglich, da die Entlastung über die vertikale Steuerstange zum Oeffnen und Schliessen der Klemmbacken erfolgt. Eine individuelle Anpassung der Federkraft an jeder einzelnen Klemmvorrichtung ist dagegen nicht möglich. In vielen Fällen ist es jedoch wünschenswert, dass die Klemmkraft der Fadenqualität angepasst werden kann und zwar unabhängig von der Lage der jeweiligen Spulstelle im Spulengatter. Bisher war es üblich, verschieden starke Federn in die Klemmvorrichtungen einzubauen, wozu aber eine aufwendige Demontage erforderlich war.Generically comparable devices are, for example, in US-A-4,598,184 or in EP-A-311 781. So far doing the clamping devices with always the same Pressurized force, each thread quality clamped with the same clamping force has been.

Es ist daher eine Aufgabe der Erfindung, eine
Vorrichtung der eingangs genannten Art zu schaffen,
bei der die Klemmkraft der Klemmvorrichtung
an jeder einzelnen Spulstelle individuell auf einfache
Weise eingestellt werden kann. Diese Aufgabe
wird erfindungsgemäss mit einer Vorrichtung gelöst,
welche die Merkmale im Anspruch 1 aufweist.
Die jeder Klemmvorrichtung zugeordnete Einstellvorrichtung
erlaubt es auf einfachste Weise, die
Federkraft an der Federvorrichtung den individuellen
Gegebenheiten anzupassen.It is therefore an object of the invention to
To create a device of the type mentioned at the outset,
where the clamping force of the clamping device
at each individual winding unit individually on simple
Way can be set. This task
is solved according to the invention with a device,
which has the features in
Besonders Vorteilhaft ist die Federvorrichtung als Druckfeder ausgebildet, die auf einem mit der Klemmbacke verbundenen Druckstift gelagert ist, wobei der Druckstift an seinem Ende mit einer Führungskulisse zusammenwirkt und durch diese gegen die Federkraft in Oeffnungsstellung pressbar ist und wobei das Widerlager der Druckfeder auf dem Druckstift verstellbar ausgebildet ist. Aus den eingangs erwähnten Patentpublikationen ist es zwar bereits bekannt, die Klemmplatte über einen Druckstift zu betätigen. Das verschiebbare Widerlager erlaubt jedoch auf einfachste Weise ein Spannen oder ein Entspannen der Druckfeder. Das Widerlager kann besonders vorteilhaft mit einem linear verschiebbaren Schieber verstellt werden, der eine Führungskulisse aufweist.The spring device is particularly advantageous formed as a compression spring on a with the Clamping jaw connected pressure pin is stored, the push pin at its end with a Leadership backdrop interacts and through this can be pressed against the spring force in the open position and the abutment of the compression spring the pressure pin is adjustable.

The sliding abutment allows tensioning in the simplest way or relaxing the compression spring. The abutment can be particularly advantageous with a linear sliding slider can be adjusted, the one Has leadership backdrop.
Die Einstellvorrichtung könnte praktisch nur aus diesem Schieber bestehen, der z.B. manuell eingestellt werden kann. Eine besonders vorteilhafte Betätigung des Schiebers kann aber auch mit einem schwenkbar gelagerten Einstellhebel erreicht werden, der an seinem freien Ende mit einem Schubgelenk in den Schieber eingreift. Der Einstellhebel kann dabei z.B. mit einem Schraubenzieher gedreht werden. Um eine unbeabsichtigte Veränderung der Position des Einstellhebels zu verhindern, kann dieser durch eine Abdeckplatte fixierbar sein, welche gleichzeitig auch die Klemmvorrichtung und die Einstellvorrichtung verdeckt und damit vor Staub und Fasern schützt. Die Abdeckplatte kann dabei eine Oeffnung mit einer Markierung aufweisen, an der die eingestellte Position des Einstellhebels ablesbar ist. Die Sicherung der einmal gewählten Einstellung durch die Abdeckplatte hat den Vorteil, dass diese Einstellung nicht durch unsachgemässe Manipulationen verloren geht. Zum Verstellen der Position müssten die Abdeckplatten gelöst werden, was nur durch autorisiertes Personal erfolgen darf. Eine besonders grosse Flexibilität der Vorrichtung ergibt sich, wenn auch die Wächternadel des Fadenwächters mit einer Zugfeder vorgespannt ist, deren gestellseitige Lagerstelle zum Verändern der Zugkraft verstellbar ist. So kann auch die Fadenspannung bzw. die Reaktionszeit der Wächternadel innerhalb bestimmter Grenzen den abgezogenen Fäden angepasst werden. Die Zugfeder kann zu diesem Zweck ebenfalls an einem schwenkbar gelagerten Einstellhebel eingehängt sein.The adjustment device could practically only consist of this slide, which e.g. manually can be adjusted. A particularly beneficial one The slide can also be operated with reached a pivoted adjustment lever be at its free end with a The thrust joint engages in the slide. The adjustment lever can e.g. with a screwdriver to be turned around. An unintentional change to prevent the position of the adjustment lever can be fixed by a cover plate be, which is also the clamping device and the adjustment device covered and thus protects against dust and fibers. The cover plate can open an opening with a marker have at the set position of the adjusting lever is readable. Backing up once selected setting by the cover plate the advantage that this setting is not due to improper Manipulations are lost. To the Adjusting the position would need the cover plates be resolved by authorized personnel only may take place. A particularly great flexibility the device results, albeit the guardian needle of the thread monitor with a tension spring is biased, the rack-side bearing is adjustable to change the pulling force. So can also be the thread tension or the reaction time the guardian needle within certain limits can be adapted to the stripped threads. The tension spring can also be used for this purpose attached to a pivoted adjustment lever be.
Klemmvorrichtung und Fadenwächter müssen innerhalb eines Spulengatters nicht zwingend beieinander angeordnet sein. Es ist jedoch vorteilhaft, wenn die Klemmvorrichtung und der Fadenwächter eine Baueinheit mit einer gemeinsamen Grundplatte bilden und wenn der Einstellhebel für die Klemmvorrichtung und der Einstellhebel für den Fadenwächter mit einer gemeinsamen Abdeckplatte fixierbar sind. So kann auch die Einstellung für die auf die Wächternadel einwirkende Federkraft auf die gleiche Weise abgesichert werden, wobei über eine entsprechende Oeffnung in der Abdeckplatte und über eine Markierung ebenfalls ein Ablesen der Einstellung von aussen möglich ist.Clamping device and thread monitor must not necessarily within a coil gate be arranged. However, it is advantageous if the clamping device and the thread monitor a unit with a common base plate form and when the adjustment lever for the Clamping device and the setting lever for the Thread monitor with a common cover plate are fixable. The setting for the spring force acting on the guardian needle secured in the same way, with via a corresponding opening in the cover plate and also a reading via a marking external adjustment is possible.

Wie insbesondere aus den Figuren 1 und 2
ersichtlich ist, besteht die Vorrichtung aus einer
Einheit, bei der die Klemmvorrichtung 1 und der
Fadenwächter 2 auf einer gemeinsamen Grundplatte
7 angeordnet ist. Diese Grundplatte ist am vertikalen
U-Profil 30 fixiert, das vor jeder vertikalen
Reihe von Spulstellen am Gatter angeordnet ist.
Der Faden 3 läuft von der nicht dargestellten Fadenspule
kommend zwischen einer beweglichen
Klemmbacke 5 und einer starren Klemmrippe 8
hindurch und wird an der Wächternadel 32 umgelenkt,
wo er in Pfeilrichtung a gegen die Wickelvorrichtung
läuft.As in particular from FIGS. 1 and 2
can be seen, the device consists of a
Unit in which the
Die Klemmbacke 5 weist eine Nabe 11 auf, in
der mit Hilfe eines Sichterungsstifts 12 ein Druckstift
6 befestigt ist. Dieser Druckstift hat an seinem
freien Ende einen im Durchmesser erweiterten abgerundeten
Kopf 9, der mit einer Führungskulisse
25 an einer vertikalen Steuerstange 24 zusammenwirkt.
Der Druckstift 6 ist einerseits in einer Bohrung
13 in der Klemmrippe 8 und anderseits in
einer Bohrung 15 in der Grundplatte 7 derart geführt,
dass sich die Klemmbacke 5 planparallel zur
Klemmrippe 8 verschieben lässt. Die Klemmbacke
5 wird dabei mit Hilfe einer Druckfeder 4 gegen die
Klemmrippe 8 gepresst. Diese Druckfeder stützt
sich am erweiterten Kopf 9 ab und liegt auf einer
als Widerlager dienenden U-Scheibe 10.The
In der dargestellten Position steht die Führungskulisse
25 in Betriebsstellung, so dass die
Klemmbacke 5 gegen die Kraft der Druckfeder 4
von der Klemmrippe 8 weggepresst wird.In the position shown, the leadership backdrop

Jaw 5 against the force of the
Hinter der Klemmrippe 8 in einer schachtartigen
Vertiefung der Grundplatte ist ein Schieber 17
angeordnet, der linear und etwa im rechten Winkel
zum Druckstift 6 verschiebbar ist. Der Schieber hat
einen Schlitz 18, der es erlaubt, den Druckstift 6 in
jeder Relativlage zu übergreifen. Während der
Schieber auf der Seite der Klemmrippe 8 plan
ausgebildet ist, hat er auf der entgegengesetzten
Seite eine Führungskulisse 19, auf der die U-Scheibe
10 gleiten kann. In seinem oberen Bereich ist
der Schieber mit einer horizontalen Nut 20 versehen.
Der Schieber wird mittels eines Einstellhebels
21 betätigt. Dieser ist drehbeweglich an der Grundplatte
7 gelagert und weist einen Schlitz 23 auf, in
den ein Schraubenzieher eingesetzt werden kann.
Ein Nocken 22 am freien Ende des Einstellhebels
bildet zusammen mit der Nut 20 im Schieber 17
ein Schubgelenk, mit dessen Hilfe die Drehbewegung
in eine Schubbewegung umgewandelt wird.Behind the
Der Fadenwächter 2 weist die bereits kurz erwähnte
Wächternadel 32 auf, die in Figur 1 jedoch
nur angedeutet ist. Diese Wächternadel hat ein
hakenförmiges Ende und ist an einem Gelenk 34
schwenkbar gelagert. Die Wächternadel ist als
Doppelhebel ausgebildet, wobei am Hebelarm 33
eine Zugfeder 35 angehängt ist, welche der Wächternadel
ein bestimmtes Drehmoment vermittelt.
Das gegenüberliegende Ende der Zugfeder 35 ist
an einem drehbar gelagerten Einstellhebel 36 eingehängt,
der zum Drehen ebenfalls mit einem
Schlitz 39 versehen ist. Das Ende des Hebelarms
33 wirkt ausserdem mit einer Schaltvorrichtung 37
zusammen, die bei einer bestimmten Hebelstellung
einen Schaltvorgang zum Stillsetzen der Maschine
und zum Aktivieren der Klemmvorrichtung 1 auslöst.The thread monitor 2 has the already briefly mentioned
Die Grundplatte 7 ist an drei verschiedenen
Stellen mit Gewindebohrungen 16 versehen. Diese
Bohrungen dienen zum Befestigen einer Abdeckplatte
26, wie aus Figur 3 ersichtlich ist. Diese
Abdeckplatte kann mit Hilfe von Schrauben 27 gegen
die Grundplatte 7 geschraubt werden. Die beiden
Einstellhebel 21 und 36 sind dabei derart in
der Ebene der Grundplatte angeordnet, dass sie
sich bei aufgeschraubter Abdeckplatte nicht mehr
verschwenken können. In der Abdeckplatte sind
jedoch Oeffnungen 28 und 40 angeordnet, durch
welche die Stellung der Einstellhebel betrachtet
werden kann. Je eine Markierung 29 und 38 auf
der Abdeckplatte erlaubt zudem ein Ablesen der
jeweils gewählten Einstellung.The
Die Abdeckplatte 26 ist seitlich mit einem Flügel
43 versehen, der über das U-Profil 30 hinausragt.
In diesem Flügel ist ein hakenförmiger Schlitz
31 angeordnet, durch den der Faden eingeführt
werden kann. Entlang dieses Schlitzes verläuft eine
obere Rippe 41, die zugleich als Auffanglager für
die Wächternadel 32 in gesenkter Position bei Fadenbruch
dient. Diese Position ist in Figur 3 durch
strichpunktierte Linien angedeutet. Eine untere Rippe
42 an der Abdeckplatte dient als rückwärtige
Begrenzung für die Wächternadel 32 bei normaler
Fadenspannung in der Betriebsstellung. Die Wächternadel
kann auf einfachste Weise durch einen
hier nicht näher dargestellten Bajonettverschluss
aus dem Gelenk 34 ausgehängt werden. Zum Verändern
der Einstellung bei den Einstellhebeln 21
und 36 genügt es, wenn die Schrauben 27 soweit
gelöst werden, bis die Einstellhebel durch die Oeffnungen
28 und 40 an den Schlitzen 23 und 39 in
die gewünschte Position gedreht werden können.The
Figur 4 zeigt nochmals die Vorrichtung gemäss
Figur 1 mit der gleichen Grundeinstellung der Federvorrichtung,
jedoch mit geschlossener Klemmbacke.
Diese Position wird bei einem Maschinenstillstand
erreicht, der z.B. durch einen Fadenbruch
ausgelöst werden kann. Lässt die Fadenspannung
plötzlich nach, so zieht die Zugfeder 35 den Hebelarm
33 in Pfeilrichtung b nach oben, wobei die
Wächternadel 32 in Pfeilrichtung c verschwenkt
wird. Die dabei aktivierte Schaltvorrichtung 37
schaltet die Wickelmaschine ab und aktiviert
gleichzeitig die Steuerstange 24, die mit Hilfe einer
nicht näher dargestellten Antriebsvorrichtung in
Pfeilrichtung d verschoben wird. Dabei gibt die
Führungskulisse 25 den Druckstift 6 frei, der unter
der Spannung der Druckfeder 4 in Pfeilrichtung e
bewegt wird. Die Klemmbacke 5 wird gegen die
Klemmrippe 8 gepresst, wobei ein Nachlaufen des
Fadens vermieden wird und dieser gespannt gehalten
wird.FIG. 4 shows the device according to FIG
FIG. 1 with the same basic setting of the spring device,
however with the jaw closed.
This position is at a machine standstill
reached, e.g. through a thread break
can be triggered. Leaves the thread tension
suddenly after, the
Soll nun die Klemmbacke 5 mit einer grösseren
Klemmkraft beaufschlagt werden und soll die
Wächternadel 32 den Faden stärker spannen bzw.
bei Fadenbruch schneller ausschlagen, so werden
die Veränderungen gemäss Figur 5 vorgenommen.
Der Einstellhebel 21 wird auf die bereits beschriebene
Weise in Pfeilrichtung f gedreht, wobei sich
der Schieber 17 in Pfeilrichtung g nach unten verschiebt.
Dabei wird durch die Führungskulisse 19
die U-Scheibe 10 gegen den Kopf 9 gepresst, die
Druckfeder 4 also dadurch mehr gespannt.Now the
Auf die gleiche Weise wird durch Drehen des
Einstellhebels 36 in Pfeilrichtung h die Zugfeder 35
mehr gespannt und damit die Wächternadel 32 mit
einer grösseren Federkraft beaufschlagt. Figur 5
zeigt die Vorrichtung wiederum bei geschlossener
Klemmbacke 5 bzw. bei abgesenkter Wächternadel
32. Die unterschiedliche Einstellung der beidern
Einstellhebel ist an der Skala auf der Abdeckplatte
26 abzulesen. Selbstverständlich kann je nach Einzelfall
auch nur eine der beiden Einstellungen verändert
