Abstract
The invention relates to a method and a device for distributing yarn wound on a cross-wound bobbin at an operating unit of a textile machine, in which a yarn guide actuated by a synchronous motor reciprocates along the axis of the rotation of the wound bobbin, whereby on the synchronous motor a time interval for the reciprocating travel of the yarn guide from one dead centre to the other dead centre is set and the position of the yarn guide is synchronized with the reference position which is between these dead centres. During each reciprocating travel, the time point of the actual passing of the yarn guide through the reference position is detected and the time difference between the time point of the actual passing of the yarn guide through the reference position and the predetermined theoretical time point of the passing of the yarn guide through the reference position is evaluated and, on the basis of the detected time difference, the duration of the rotation of the synchronous motor changes until the respective reciprocating travel is finished, which also leads to the change of the length of the path of the yarn guide from the reference position to the dead centre, to which the yarn guide is currently approaching.

Accompanying drawing explanation
Schematically show in the accompanying drawings example according to an embodiment of the invention, wherein Fig. 1 represents for distributing the front elevation of the device of winding yarn, and Fig. 2 is the lateral plan along the direction P in Fig. 1.
The specific embodiment
In fact the High Performance of sir jet spinning machines does not allow to use the common driver system for a plurality of thread-carriers by a long traverse bar.According to the wind2 of the independent driving of background technology, make it possible to increase the reciprocating frequency of thread-carrier, but still there is problem to be solved, i.e. the reciprocating dynam of the thread-carrier under the extreme frequency of this motion and about the complexity of the control process of this motion of the intended shape of yarn package.
Shown in Fig. 1 and Fig. 2 according in the example of the embodiment of yarn distribution device of the present invention, in the framework 1 of the operating unit of machine, the driving roller 11 by unshowned driving electrical motor driven is installed.
Mound bobbins 2 and the Surface Contact that drives roller 11, mound bobbins 2 is arranged in the unshowned wind2 of operating unit in known manner.The guide rail 12 of thread-carrier 3 is arranged in framework 1, and guide rail 12 is parallel to the rotation axis that drives roller 11 and mound bobbins 2.Be provided with abreast with guide rail 12 tape handler 4 that comprises driving pulley 41 and driven pulley 42.Driving pulley 41 and driven pulley 42 are positioned at the positive outside that drives roller 11.Driving pulley 41 is arranged on the output shaft of synchronous motor 43.Driven pulley 42 connects with unshowned take up member.Driving pulley 44 turns round in perpendicular.Driven pulley 42 connects with unshowned tightening device, or in another embodiment, the unshowned tension wheel that the tensioning with 44 arranges contiguously by the inferior division with 44 solves.
Tape handler 4 is used flat rubber belting 44, and the friction surface of flat rubber belting 44 is by the coating formation with sufficiently high friction coefficient, and wherein flat rubber belting 44 also partly conducts electricity to eliminate the appearance of static charge.The carrier 31 of the thread-carrier 3 of being made by the material with low-friction coefficient is installed in a not shown manner in the top set with 44.Carrier 31 at thread-carrier 3 tightens intrinsic independently ceramic guiding elements 32, and ceramic guiding elements 32 contacts with the distribution yarn of running.
The carrier 31 of thread-carrier 3 can be arranged in the groove 13 of guide rail 12 movably, and it is considered and realizes minimal wear and have crust polishing and have minimum friction coefficient.Middle part at the width of mound bobbins 2, this means the middle part of the distance V between dead point U1, the U2 of thread-carrier 3 motions, at guide rail 12, tighten intrinsic contactless position sensing device 5, position sensing apparatus 5 is provided with the magnetic pickup device 51 towards the path of navigation of thread-carrier 3.Thereby at the vertical wall of the groove 13 towards guide rail 12 and in the surface of the carrier 31 of the thread-carrier of Non-contact-type sensing device 5, be provided with permanent magnet 33, permanent magnet 33 is as the marking element of thread-carrier 3.In unshowned embodiment, use electromagnet to replace permanent magnet 33.
Be fastened to the driving synchronous motor 43 of guide rail 12 and position sensing apparatus 5 and all connect with using the unshowned control unit of operating unit of the weaving loom of feedback signal, by this feedback signal, notify the state of control unit about actuator.
According to the unitary construction of yarn distribution system of the present invention, take the minimum moment of inertia of movable parts attaches most importance to and solves as mechanical-electronic system.Therefore can realize especially the minimum and maximum acceleration/accel of reciprocating member.
This scheme especially object is the control of the member of belt wheel 4 and the motion of thread-carrier 3, or is more specifically the mainly position in the scope of the distance V between these dead points U1, U2 in the region of dead point U1, U2 of thread-carrier 3.
In this connection, in example according to an embodiment of the invention, use the high speed disc two-phase motor 43 with utmost point low-inertia force square as driving synchronous motors 43.For example, its maximum speed is 5000min
-1and moment of inertia is 7kgm
2.10
-7.
The actual position of thread-carrier 3 is measured by sensing device 5, the marking element of sensing device 5 identification thread-carriers 3 time point that namely permanent magnet 33 is positioned with respect to the magnetic pickup device 51 of sensing device 5.The actual position of thread-carrier 3 is only recorded at the middle part apart from V, this means the accurate middle part between dead point U1, the U2 of thread-carrier 3 motions.
Starting reel for yarn around before, the synchronous of thread-carrier implemented by the magnetic pickup device 51 of sensing device 5.The reference position of thread-carrier 3 is only limited by the sensing device 5 that is immovably positioned at the middle part, path of thread-carrier 3.During thread-carrier 3 passes through along an one sense of motion and another sense of motion, by sensing device 5, measured the actual position of thread-carriers 3.The time point that record passes through, wherein monitors the time deviation with the predetermined point of time of passing through.Record this deviation, difference occurs it being due to 44 slippages on the surface of driving pulley 41.The time point that permanent magnet 33 is passed through around the magnetic pickup device 51 of sensing device 5 is passed to the control unit of the operating unit of weaving loom as incoming signal.The time deviation of the time point passing through based on reality and the predetermined point of time of passing through, generates slippage corrected correction factors as time data, and slippage corrected correction factors is deducted or added from predetermined (theory) time length in the path of thread-carrier 3.Resulting persond eixis is used to the stroke of crank motion subsequently of the thread-carrier controlled by synchronous motor 43.
The time length of motion (rotation) by change with the synchronous motor 43 of feedback, regulates the dead point U1 of its motion, the position of the thread-carrier at U2 place.Then by changing the path of thread-carrier 3, carry out the correction of executing location, by the way, when each crank motion stroke of thread-carrier, regulate practically dead center position U1, U2, predetermined to realize (theory) position.It is constant that thereby the kinematic velocity of synchronous motor 43 keeps.
The method according to this invention and become simpler by controlling the system of the motion of thread-carrier 3 for the device of implementing the method, also add and adopted disc type two-phase synchronous motor 43, and its constant rotating speed is all reducing the negative effect of force of inertia aspect the package quality installing and service life and reliability significantly.
