Description
Elektromagnetisch gesteuertes Kupplungs- und Bremsaggregat Im Spinnmaschinenbau ist es vielfach erforder lich, von waagrechten Antriebswellen die einzelnen senkrechten Spindeln, die mittels Schneckenrädern von der Antriebswelle angetrieben werden, stillzuset- zen. Gebräuchlich sind z. B. Rutschkupplungen, die bei Fadenriss, sobald man die Spindel von Hand fest hält, durchrutschen. Das Verknoten der Fäden wird dann eine gewisse Zeit in Anspruch nehmen, wobei die Rutschkupplung in Tätigkeit tritt. Bekanntlich ist bei dieser Manipulation eine gewisse Geschicklich keit in der Bedienung notwendig, denn je länger das Verknoten dauert, um so länger muss auch die Rutschkupplung arbeiten.
Die Rutschzeit und Wär meentwicklung hängen also von der Fingerfertigkeit des Bedienungspersonals ,ab. Durch die vorliegende Erfindung wird die Gestaltung eines Kupplungs- und Bremsaggregates bezweckt, welches das Festhalten der .Spindel von Hand erübrigt.
Der der Erfindung zugrunde liegende Gedanke besteht darin, dass bei einem elektromagnetisch ge steuerten Kupplungs- und Bremsaggregat von einem feststehenden Elektromagneten bei Einschalten des Stromes eine Federdruck-Reibungskupplung gelüf tet und eine Elektromagnet-Bremse eingeschaltet tet wird.
Auf der Zeichnung ist der Erfindungsgegenstand in. zwei beispielsweisen Ausführungen dargestellt, und zwar veranschaulicht: Fig. 1 den Längsschnitt durch eine Elektroma- gnet-Bremse und eine Federdruck-Reibungskupplung mit feststehendem Magneten; Fig. 2 den Längsschnitt durch die zweite verein fachte Ausführung.
Wie aus Fig. 1 ersichtlich, ist das Schneckenrad 1 entweder mit Gleit- und/oder Rollen-Lagern auf der Antriebswelle 2 leicht gängig gelagert. Es treibt die Garnspindel 3 an. Auf einer Seite des Schneckenra des 1 befindet sich ein Bremsteil aus formgepresstem Reibwerkstoff 4, auf der Gegenseite ist eine Anker scheibe 5 durch Bolzen 6 mit dem Bremsteil 4 ver bunden. Die Druckfedern 7 drücken den Reibkörper 4 gegen den Mitnehmer 8, wodurch die Verbindung von Welle 2 über Mitnehmer 8 und Bolzen 6 rauf das Schneckenrad 1 erfolgt.
Wird das gegenüber dem Anker 5 befindliche Elektromagnet-,System 9 einge schaltet, zieht der Magnet den Anker 5 und damit den Reibkörper 4 vom Mitnehmer 8 ab. Die Reibflä che 10 am Anker 5 wird gegen den feststehenden Spulenkörper 9 elektromagnetisch gepresst und bremst das Schneckenrad 1 ab. Sobald die Spule 9 abgeschaltet wird, drücken die Federn 7 den Reibring 4 gegen den Mitnehmer 8 und es erfolgt die Mit nahme des Schneckenrades 1. Die axialen Kräfte wer den mittels Springring oder .Stellring 11 @aufgenom- men.
Bei der vereinfachten Ausführungsform gemäss Fig. 2, die der ersten Ausführungsform gleicht, fallen die Rollen- und Kugellager aus, sowie die auf dem Bolzen 6 befindliche Regulierungsmutter.
Bei der Anwendung eines der gezeichneten und beschriebenen Aggregate bei Spinnmaschinen kann beim Fadenriss durch einen Fadenfühler sofort auto matisch über einen Mikroschalter oder ähnliche Ein richtungen über den Elektromagneten die Bremse eingeschaltet und die Federdruck-Reibungskupplung abgeschaltet werden. Dadurch wird das den Antrieb bewirkende Rad entkuppelt und durch die Bremse festgehalten und damit die senkrechte Spindel. Die Antriebswelle wird von; der Spindel getrennt; sie kann automatisch weiterlaufen und ohne Störung die übrigen Spinnmaschinen-Spindeln antreiben.
Nach Behebung des Fadenrisses und Auflegung des Fadens über den Fadenfühler kann dieser wieder automa tisch den Elektromagneten ab- und damit die Bremse ausschalten und zwangsläufig die Federdruck-Kupp- lung die Verbindung von Antriebswelle mit Spindel welle herstellen.
Electromagnetically controlled clutch and brake unit In spinning machine construction it is often necessary to stop the individual vertical spindles of the horizontal drive shafts, which are driven by the drive shaft by means of worm gears. Common are z. B. Slipping clutches that slip through when the thread breaks as soon as you hold the spindle firmly by hand. The knotting of the threads will then take a certain amount of time, during which the slip clutch is activated. It is well known that this manipulation requires a certain degree of skill in the operation, because the longer the knotting takes, the longer the slip clutch has to work.
The slip time and heat development therefore depend on the manual dexterity of the operating personnel. The aim of the present invention is to design a clutch and brake unit which eliminates the need to hold the spindle by hand.
The idea on which the invention is based is that in the case of an electromagnetically controlled clutch and brake unit, a stationary electromagnet when the current is switched on releases a spring-loaded friction clutch and an electromagnetic brake is switched on.
In the drawing, the subject matter of the invention is shown in two exemplary embodiments, specifically illustrated: FIG. 1 shows the longitudinal section through an electromagnetic brake and a spring-pressure friction clutch with a stationary magnet; Fig. 2 shows the longitudinal section through the second simplified version.
As can be seen from FIG. 1, the worm wheel 1 is easily mounted on the drive shaft 2 either with sliding and / or roller bearings. It drives the thread spindle 3. On one side of the worm gear 1 there is a brake part made of compression-molded friction material 4, on the opposite side an armature disk 5 is connected by bolts 6 to the brake part 4. The compression springs 7 press the friction body 4 against the driver 8, as a result of which the shaft 2 is connected via the driver 8 and bolts 6 up to the worm wheel 1.
If the electromagnet located opposite the armature 5, the system 9 is switched on, the magnet pulls the armature 5 and thus the friction body 4 from the driver 8. The Reibflä surface 10 on the armature 5 is electromagnetically pressed against the stationary bobbin 9 and brakes the worm wheel 1. As soon as the coil 9 is switched off, the springs 7 press the friction ring 4 against the driver 8 and the worm wheel 1 is taken along. The axial forces are absorbed by means of the spring ring or the adjusting ring 11 @.
In the simplified embodiment according to FIG. 2, which is similar to the first embodiment, the roller and ball bearings fail, as do the regulating nut located on the bolt 6.
When using one of the units drawn and described in spinning machines, the brake can be switched on and the spring-loaded friction clutch switched off automatically when the thread breaks by a thread sensor using a microswitch or similar devices via the electromagnet. As a result, the wheel causing the drive is decoupled and held by the brake, and with it the vertical spindle. The drive shaft is from; the spindle separated; it can continue to run automatically and drive the other spinning machine spindles without interference.
After the thread breakage has been rectified and the thread is placed over the thread feeler, the latter can again automatically switch off the electromagnet and thus switch off the brake and the spring-loaded clutch inevitably establish the connection between the drive shaft and the spindle shaft.
