Definitions
- the invention relates to a delivery mechanism for guiding a thread in a textile machine according to the preamble of claim 1.
- delivery mechanism In order to guide one or more threads in the production of threads or the treatment and further processing of threads within a textile machine, so-called delivery mechanism are used. Such deliveries have at least one driven conveyor roller, on whose roller circumference one or more threads are guided. A multiple Operaumschlingung of the conveyor roller through the thread is achieved by one of the conveyor rollers associated guide roller, so that the thread is guided with multiple wrapping around the two rollers.
- delivery mechanism is known for example from DE 1 926 308.
- the known delivery mechanism has a driven conveying roller and a conveying roller associated freely rotatably mounted guide roller. To guide the thread with multiple Operaumschlingung is guided on the roll shells.
- winders which require a process interruption, occur, in particular, on the driven conveyor rollers of the delivery mechanism.
- the feed roller is directly associated with a winding sensor, which cooperates with a switching means to turn off the drive train.
- the intermediate space between the two rolls of the winding sensor is arranged, which is held with a feeler end at a short distance on at least one of the roll coats of the rolls.
- the winding sensor is connected via an actuator to a switching means which triggers a switching pulse for switching off the drives upon movement of the winding sensor.
- a switching means which triggers a switching pulse for switching off the drives upon movement of the winding sensor.
- shutdown systems are extremely complex in structure, wherein the mechanically generated signal is converted in a switching means and fed via lines of a control device, which then drives a Fadenhacker for process interruption.
- a delivery mechanism which is associated with a Fadenhacker directly in the yarn path.
- the thread chipper can be activated via a switching device that interacts with a winding sensor.
- the Wickelfuhler is associated with this at least one roll shell of the rolls of the delivery plant.
- the upstream thread chipper is thus activated by triggering the winding sensor, so that no further winding formation is formed on the driven roller.
- the switching means is formed by a contact switch, which is connected in a directly connected to the drive means power line and which has at least one switchable interrupt contact point for interrupting the power supply of the drive means.
- the invention is directed to the previously known systems, in which the winding formation signaled by winding sensor is used to generate a control pulse with the switching means, by which a control for switching off a drive means or preferably the entire processing point is activated.
- the invention in contrast, a completely new way by the triggered by a winding on a roller signal is used directly to interrupt the power supply of the drive means.
- a very fast delay-free shutdown of the drive means is achieved.
- the control measures required for upstream process units and downstream process units are triggered only downstream. Such control commands could be triggered, for example, by the control device associated with the drive device, which registers the power failure at the drive means.
- the contact switch is preferably designed such that in each case a breaker contact point is provided per phase of the power line.
- Each of the breaker pads has a movable spring contact element for releasing and closing the contact point, the actuator having a plurality of cams acting on the spring contact elements.
- the actuator is designed as a rotatable switching shaft, is attached to the free end of the winding sensor and as having at least one cooperating with the contact switch cam.
- the switching shaft is preferably rotatably supported substantially parallel to the axis of the conveying roller such that the switching cam is guided between a home position and a detent position.
- the rest position is the normal operating position in which the electric motor is supplied with power.
- the switching cam of the switching shaft acts on the spring contact elements, so that the power supply is interrupted.

- Shift lever is formed, which opposite to the sensor end a handle end having.
- the sensor end is preferably aligned with an angle of inclination relative to the axial center of the conveyor roller to the direction of rotation of the conveyor roller, so that the direction of rotation of the switching shaft and thus the transition from the rest position is predefined in a detent position.
- the design of the winding guide as a shift lever also has the particular advantage that the winding sensor can be used simultaneously as a manual switch to turn off the delivery mechanism. This training is preferably used at delivery plant, which are driven in a variety by a group converter. This allows individual processing points to be switched on and off independently of each other despite a group control.
- the development of the invention is preferably intended for use in textile machines, in which the feed roller, the guide roller, the three-phase motor and the selector shaft are held on a plate-shaped carrier, wherein the roller shells of the rollers and the free End of the shift shaft held winding sensor are arranged on a front side of the carrier.
- the feed roller, the guide roller, the three-phase motor and the selector shaft are held on a plate-shaped carrier, wherein the roller shells of the rollers and the free End of the shift shaft held winding sensor are arranged on a front side of the carrier.
- the temperature protection device has a prestressed deflection means which is fixedly coupled to the control shaft for actuating the contact switch. Wherein the deflection means cooperates with a temperature-sensitive securing means for solving the bias voltage and wherein the dissolved deflection means causes a torque for rotating the switching shaft.
- securing means can be used in this case bimetallic sheets, which solve a deformation of a bias of the deflection.
- the securing means by a fusible plastic element which melts when a certain temperature of the engine is exceeded and thus releases the prestressed deflection means.
- the delivery mechanism according to the invention is thus characterized by a high level of operational reliability with minimal control effort. Thus, a large number of such delivery plants can be operated by a group control.

It is essential here that the switching movement initiated by the winding sensor due to a yarn winding propagates directly and leads to the interruption of a drive means of the roller leading the yarn package. Delay times and, in particular, expensive apparatus by means of signal flow and controls can thus be avoided.
- the mechanically triggered movement of the thread winding can be implemented directly in a circuit interruption, so that a very fast shutdown and thus an overload protection of the drive means is ensured. LIST OF REFERENCE NUMBERS
