Summary of the invention

The embodiment of the present invention includes a kind of for monitoring the monitoring device of the manufacture of composite yarn in ring spinning apparatus. Composite yarn according to the present invention usually has the cored including at least one, this at least one handled by stretching-machine it is thick The fiber of yarn is encapsulated.Depending on application field, which is suitable for the composite core-spun yarn that monitoring includes more than one cored The manufacture of line.The monitoring device is arranged in the upstream of the import of relative stretching-machine relative to the moving direction of rove.

Monitoring device according to the present invention generally includes the shell with actuator, which is arranged to can be first It linearly and/or is rotatably shifted between the first position of locking and the nonlocking second position on direction.Actuator is pre- Know for (foresee) depend at least one be not present and/or another fault condition itself (directly) or via The fiber that other devices (indirectly) interrupt at least one rove is flowed into spinning process, which is arranged in associated therewith Stretching-machine downstream.

Monitoring device further comprises trigger mechanism, which includes can in a second direction linearly and/or can The trigger element rotatably shifted has the first position for the latch being locked in actuator in the first position of locking and incites somebody to action Actuator is discharged into the second position of the non-latch of the nonlocking second position.Trigger element precognition for directly or indirectly Indicate at least one monitoring element interaction of silk as described herein being not present.

The present invention provide trigger element precognition for have simultaneously the relative silk of instruction there is no (or therefore Barrier) ability at least two monitoring elements interaction advantage.In this situation, trigger element serves as can be by interconnected The difference element that independently activates of any monitoring element.Preferably, trigger mechanism is at least partially disposed in shell.

If there is two monitoring elements, then monitoring device be preferably built into so that a silk to trigger mechanism and and its The activation of the actuator of interconnection can interrupt second supply.

In advantageous variant, trigger element, which is arranged to, to be rotated around trigger element rotation axis.If actuator quilt Be arranged to can resist spring the pre-tensioned first direction of power on linear displacement, then good monitoring result may be implemented. Alternatively or additionally, can be arranged to can be relative to actuator linear displacement for trigger element.

In advantageous variant, trigger element includes the first locking member and actuator includes the latched position in actuator In the second locking member for being interacted with the first locking member.If the first locking member relative to the second locking member about can exist The interaction of the element of (be in 90 ° of angles) displacement in vertical direction and arrange, then good result may be implemented.Pass through the change of angle Change, sensitivity can be adjusted when trigger element discharges actuator.First locking member can for example be arranged on trigger element The recess portion at place, and second element can be arranged on the protruding portion at actuator.Protruding portion can be integrally formed in actuator Place.If durable components (such as metal material system by such as steel of the protruding portion in snap-on in the corresponding recess at actuator At) form, then realize good result.To ensure accurate operation, actuator can resist the power of spring and pre-tensioner.Depend on In design, alternatively or furthermore it is possible to for example by gravity and/or by the way that actuator is interconnected to the removable of spinning equipment Partially (such as, being arranged in one of the roller of entrance of relevant stretching-machine) obtains the driving option of actuator.

Another additional features can be bolt element, assigns user for actuator and is bolted to the first latch position In therefore prevent the chance of actuator trigger and displacement.

Further additional features refer to using a rocker arm but the case where there are the second rocker arms in monitoring device.Therefore, The corresponding rocker arm being not used by needs to be otherwise permanently secured in its position, so that gravity, which does not make rocker arm be moved to it, makes trigger element In the position of triggering.This can be realized by the stopper that may be mounted on corresponding rocker arm.Stopper is against monitoring device Shell support rocker arm weight, be preferably close to the position that rocker arm tilt axis is located at.

Further additional features can be used for accommodating monitoring device to the different setting angles of stretching-machine, to generate difference Thread tension.Orientation depending on monitoring device relative to ring spinning apparatus, the tension of silk and the center of gravity of at least one rocker arm It can be dramatically different.Therefore, the spring element combined with spacer can be used to ensure that at least one rocker arm against trigger element Correct contact pressure and so that trigger is moved to the sufficient mechanical force moment in the second non-latch position.Spring element is against triggering The lever of element pressing rocker arm.Spacer can be used for further adjusting the position of at least one rocker arm and therefore corresponding silk The position of the center of gravity of tension and corresponding rocker arm.The position of center of gravity is important, because it, which influences rocker arm, surrounds rocker arm sloping shaft The magnitude of the gained mechanical force moment of line.This mechanical force moment needs sufficiently big, it is sufficient to trigger be made to shift and therefore will start Device releases latch.

It includes first encapsulated by the fiber of rove that the invention further relates to a kind of for producing in spinning process With the method for second compound core-spun yarn.Herein, in silk in the spinning point for being arranged in stretching-machine downstream by rove Before fiber encapsulating, first and second tension is monitored by the first and second monitoring elements.Two monitoring elements are via touching Hair mechanism is interconnected to actuator, in the case where the tension at least one of silk drops to pre-defined value or less, the triggering machine Structure activates actuator by the interconnection of trigger mechanism, so that interrupting supply of the stretching-machine to the fiber of rove via actuator.

Fiber can be interrupted further by being interconnected at least one separator of actuator, because of at least one separator Acted in the region of the import of stretching-machine at least one rove and therefore chopped fibre to spinning point supply so that Spinning process stops.

Preferably, at least one separator design in one way so that, if actuator displacement, separator encloses Around its basement tilt and it is pushed between a pair of of conveying roller.It was demonstrated that separator is advantageously designed to reaping hook shape, take Lock is on the respective drive roller of the conveying roller pair.If actuator is in the first position of locking, driven roller and silk and/ Or the rove contact of delivering silk.In the nonlocking second position, the part in separator inclination and the reaping hook portion of separator exists It is moved between driven roller and corresponding silk and/or rove, to prevent from contacting.Other designs of separator are also possible.

If monitoring a silk and this thread being broken, only need to stop remaining rove.Therefore, it is necessary to interrupt State the contact of rove with the driven roller (position for introducing rove) of the input roller pair of ring spinning apparatus.

However, two separators are preferably used, make if monitoring two silks and the fracture of only one silk simultaneously It obtains and also stops remaining second beside rove.Different places in ring spinning apparatus introduce silk and rove and into one Step promotes to introduce.Rove is introduced into and is conveyed at input roller, and silk is thus introduced at conveying roller.Therefore, it acts on not The sufficient of all yarn components is advantageously used in two different separators on roller to stop.
