Definitions
- the invention relates to a device for retracting and Advancing a thread treatment element relative to one Thread run of a textile machine with a thread treatment element with a drive mechanism connecting a drive motor.
- thread tensioners are used and / or waxing devices for influencing the thread or thread treatment used.
- This thread tensioner or waxing equipment must be removed a thread defect in the subsequent manufacture of one Thread connection to be opened so that a top thread and a Bobbin thread can be safely inserted into the thread path.
- the cleaning of Thread errors making the thread connection and that Opening and closing of the thread tensioner and waxing device automatically.
- To open the thread tensioner for example one of the clamping plates from the opposite clamping clamp withdrawn and then advanced again.
- a waxing roller is used to open a waxing device withdrawn from the threadline and then pushed back into the thread course. The necessary for this Movements are often done via cams, bellcranks and Linkage tapped from the drive of the winder.
- the invention has for its object a device of the type mentioned at the beginning to create the inexpensive easy to control and flexible regarding the Opening and closing times are adjustable.
- the drive mechanism two by turning the drive motor back against his normal sense of rotation contains elements which can be rotated relative to one another, one of which is in reverse with the drive motor coupled and the other locked in the reverse direction against rotation is and that a Twisting the elements against one another onto the thread treatment element transmitted axial movement is applied.
- the drive motor is used to retract and advancing the thread treatment element used.
- This drive motor has for technological reasons for the Normal operation a given direction of rotation.
- For withdrawing of the thread treatment element is simple the direction of rotation of the drive motor is reversed.
- the advancement occurs when the drive motor is back for normal operation turned on with its given direction becomes.
- the two elements are in supported against each other in the axial direction by means of support means and loaded against each other by means of a spring means.
- helical surfaces are used as support means intended. Such spiral surfaces can be easily manufacture and result in a safe function.
- the two elements towards each other in the axial direction of a spring means are loaded.
- the spring means in Connection with the drive motor driven in normal running direction sure the two items are back in their operating position ingest, i.e. that the thread treatment element is pushed back into the thread course.
- the object is achieved in that Means for preventing the indirectly drivable from rotating Tensioner plates are provided that the directly drivable Tensioner plate around the division of the ring-shaped permanent magnets relative to the indirectly driven clamping plate is rotatable, and that at least one of the two tension plates together with the associated permanent magnets in the direction the repulsive force of the permanent magnets is resilient.
