The major defect of this solution is: recover at work station to need in each cycle of spinning that operator's is manual Movable.
Therefore, it is intended to guarantee that the component of work station allows the most in some cases after its prior interrupt complete Automatically recover spinning, therefore greatly reduce the needs to the manual operation carried out by operator.
The most apparently, open-end spinning frame has the good condition reaching this target, the work station bag of this open-end spinning frame Include spinning unit, two-sided by the function solenoid part being coaxially mounted to radial magnetic bearing of the spinning rotor of this spinning unit Open cup forms, and the electrical rotation drive and drive system by independent electromagnetic bearing forms, wherein, by spinning The cup-shaped one-tenth of yarn, be typically one side open type and the original spun rotor that is fixedly mounted on axle by integrated spinning rotor Replacing, this integrated spinning rotor not only includes the function element for spinning, also includes for driving and stable element, according to WO 2008/080372 or CZ 294707, spinning rotor is arranged in electromagnetic bearing and is driven by electrical rotation drive Dynamic.
Solution mentioned above for integrated spinning rotor has turned out it in application in long-time test In interests and the chance of open-end spinning frame, and develop integrated spinning rotor the most further.Additionally, in this material passage In layout, it is assumed that due to yarn end phase despining in the groove of spinning rotor, will deposition in the groove of spinning rotor Very small amount of impurity, sees article: in open-end spinning the deposition in the groove of rotor (Nield, R., Abadeer, E.F.: Deposits in the rotor groove in open end spinning, Part I. – IV. Journal of the Textile Industry Vol. 70 No. 7. No. 9. (1979)).
According to CZ PV 2,012 592, the integrated spinning rotor along independent electromagnetic bearing and drive system is arranged on and spins In the lid of yarn unit, but, the feed arrangement of sliver and the segregation apparatus of sliver are arranged in the main body of spinning unit, because of This, be arranged on the lid of spinning unit the body upper of spinning unit and make it can tilt from the main body of spinning unit.This cloth Put up to 150 000 min allowing spinning rotor-1And higher revolution spins, form all sons for spinning unit Unit, especially for electromagnetic bearing and the control of drive system and power electronic equipment, for radial magnetic bearing stator and The cooling of the stator of electrical rotation drive and installation and for the cloth for impurity is removed from the region of noil The structural sample put and cheap solution.Lid is made to tilt upward, and when tilting, by radial magnetic bearing forever Integrated spinning rotor is fixed in settling position by the magnetic field of magnetic Magnet, and as a result, makes the easily accessible operation of its rotor Person, if necessary, this operator can utilize cup to easily remove integrated spinning rotor.
Interrupt semi-automatic open-end spinning frame work station at spinning operation after, the operator at work station according to The layout of the work station of machine performs to restart the preparation process of spinning, i.e. cleaning spinning rotor, detection yarn end, hands Dynamic measure needed for spinning enters length of yarn, prepare for spin the yarn end entered and be inserted into tractive funnel or In the outlet opening of person's tractive pipe.Due to low pressure, by tractive funnel or pipe, yarn end is drawn in spinning room, spins at this Yarn is provided with spinning rotor in room.Subsequently, the controlling organization of operator's manual actuation work station, automatically to recover spinning process, Or the process as the case may be, automatically recovering to spin by closing the lid of spinning unit to activate.
CZ 303613 B6 describes the simplification process recovering spinning, wherein, after cleaning spinning rotor, is not also having In the case of measuring the length of yarn needed for spinning enters, yarn is incorporated in tractive pipe, and by tractive pipe and tractive This yarn is sucked in the low-pressure channel until spinning unit by funnel, with by the ingate of spinning rotor.Spin starting recovery After yarn process/period, interrupt yarn and the edge by yarn rotor forms spinning and enters yarn end.In this solution In scheme, reduce the activity of operator and by preparing the shadow that the quality of butt joint produces for the end of entrance of spinning Ring;But, enter in operation in each spinning, the existence of operator remains necessary.
The purpose of the present invention lies also in during minimizing restarts spinning in semi-automatic open-end spinning frame and is held by operator The needs of the manual operation of row, and perform at least part of full-automatic spinning entrance process.
Summary of the invention
The purpose of the present invention is realized by the open-end spinning frame according to the present invention, and the principle of this open-end spinning frame is: spinning The tiltable lid of unit is attached to for making it tilt at least in part such that it is able to be drawn in low-pressure channel by yarn end And for being interrupted the component of yarn by the edge of spinning rotor, therefore, component is by the control unit of the work station of machine Control.Meanwhile, spinning unit is provided with for making lid tilt to allow manually cleaning spinning rotor or permission by operator more Change the component of this spinning rotor.Owing to confirming to be provided with being operated alone of being integrated in magnetic bearing having the most statistically In the layout of the spinning unit of the two-sided open rotor of device deposition have very small amount of impurity the fact that, in many situations Under, in the case of the groove not having thorough mechanical cleaning spinning rotor, spinning can be restarted at work station.Therefore, The most apparently, attempt the component by being used alone work station, at work station after independent interrupt spinning process the most again Start spinning, and the most in the event of a failure call operation person time more cost effective.
Control unit is further attached to two driving means of the drum-type storage device of yarn, such as, according to patent CZ 303880, the rotation cylinder of the drum-type storage device of this yarn is attached to the first bidirectional driving apparatus, and rotation compensation Arm is attached to described second bidirectional driving apparatus.
If having the drum-type temporary storing device composition draw-off mechanism of the yarn rotating cylinder and rotation compensation arm, that Adding the reliability automatically recovering spinning, it is straight from spinning unit by the rotation cylinder of drum-type makeshift device that this means yarn Connect extraction, with by the quality of yarn and the sensor of existence.In this arrangement, at work station, stop the time interval of spinning Become the shortest, and, although additionally, improve the success rate stopping yarn end in spinning unit, but this permits Permitted the component with high spinning entrance success rate by work station and automatically initiated the spinning entrance cycle.
It addition, can deposit at least length of yarn along its circumference is critically important for drum-type temporary storing device, should Length of yarn needed at least length of yarn enters with the intended defective yarn of maximum possible, follow-up spinning, Yi Jiting Only manipulating yarn is corresponding with the length of yarn stopped in the case of not having yarn breakage needed for spool.
Similarly, if the control unit of the work station of machine is provided with the relevant work station for detecting and control machine All actuators and the component of operation of sensor, then this is by highly beneficial, with the help of this component, when needs stop During spinning, at work station stop spinning operation, and assess termination spinning after at the outlet opening of spinning unit, there is yarn Line, therefore, in the case of yarn is non-existent, the signal of control unit provides call operation person, and situation about existing at yarn Under, the component of its actuating work station is automatically to recover spinning process, without recovering spinning, then it provides calling behaviour The signal of author.The determining in time of the person that makes call operation the most when being necessary further saves the time and improves The efficiency of machine, because it attempts recovering spinning in the case of preventing from there is not yarn in spinning unit, this certainly can failure.
At each work station, what the control unit of work station was at least connected with the feed arrangement to sliver is operated alone dress Put, have two of drum-type temporary storing device of the individual drive of the spinning rotor of corresponding magnetic bearing, yarn individually Driving means, wind spool hoisting mechanism driving means, for opening the driving of component of the lid of spinning unit Device, the existence of yarn and the sensor of quality and the device for detection yarn breakage in time, in order to their operation is same Step purpose, all of which interconnect, wherein, in order to remove defect and fracture, be provided with in a control unit for Remove defect and fracture and for recovering the program that spinning enters, therefore, without restarting entrance process of spinning, that The signal of the control unit of work station provides call operation person.
If the component that control unit is given by the work station using machine after the signal of call operation person makes The lid wing drop of spinning unit is to the order of fully open position, then achieve the time shortened used by operation element station.As a result, When operator arrives, lid has already turned on, and operator can start to clean spinning rotor.
Another improvement is to be directed to spinning rotor to remove the compressed air of fiber impurity and fiber remnants by use Flowing and realize, be deposited on wherein during fiber impurity and fiber remnants spinning process previously, compressed air stream is by machine The control unit of the work station of device controls.The lid partially opened generally utilizing spinning unit performs cleaning, and by The impurity removed by compressed air is discharged in the low-pressure channel of spinning unit.
From the viewpoint of simple structure and functional reliability, if compressed air stream is by being arranged on for providing separation fibre One or more nozzle in the lid outlet of the transfer passage of dimension generates, then this is by highly beneficial, and the outlet of this lid is positioned at double The opposite, ingate of face open rotor.
In order to stop spinning, the control unit of work station when there is the unpredictable natural fracture of yarn during spinning It is attached to the device for detecting yarn breakage at relevant work station in time.This device, the control unit of work station, Yi Jifang The reaction guaranteeing to stop spinning at work station of the component of yarn unit is single for the end of the yarn of fracture is maintained at spinning It is sufficiently fast in unit.The factor promoting this process makes the rotation cylinder of yarn temporary storing device and stores dress temporarily The yarn snap back of the q.s rotated on cylinder put.
Device for detection yarn breakage in time can be by being integrated in magnetic bearing (seeing CZ 2012-0720 A3) The motor of the individual drive of spinning rotor electric current input sensor and/or for during spinning measure yarn tension Device composition, device of yarn tension should be measured during spinning and be arranged on before draw-off mechanism, or if it is desirable, yarn Line tension can be monitored by means of the machine torque measured needed for driving the cylinder of drum-type temporary storing device.
Enter in order to carry out spinning after the action taked by operator, the control unit connection of each work station It is connected to the component of work station, to start, by operator, entrance process of spinning.
Especially, this component can be made up of the sensor of the position of the tiltable lid of button or spinning unit.
If the compensator arm of yarn rotary drum-type temporary storing device is attached to for measuring being attached to of machine torque The component of the control unit of work station, then being achieved that another improvement of function, this is used for measuring being attached to of machine torque Subtract because of the yarn breakage before wind for this torque if the component of the control unit of work station is provided with Few to zero, so provide the component of the signal stopping spinning and call operation person.Thus, it is possible to store dress in drum-type temporarily Put detection yarn breakage between the coil in spool, and in this manner it is achieved that prevent yarn in the case of this fracture Accumulate uncontrollably in temporary storing device.
When the existence of yarn and the sensor of quality with the lid of spinning unit on time, improve monitoring in spinning unit There is yarn, therefore, the tractive pipe being connected to tractive funnel extends up to the sensing field of sensor or even after sensor Face.Sensor can also be arranged on the lid of spinning unit.
It is for restarting the principle of the method for spinning at the work station according to the open-end spinning frame of the present invention: After interrupting spinning operation, it is assumed that there is yarn in spinning unit, and given by the program of control unit spinning of sening as an envoy to single The order that the cover ground of unit tilts, and the yarn from the cylinder of temporary storing device oppositely unwinding is drawn into low pressure leads to In road, therefore, interrupt yarn by the edge of the ingate of spinning rotor, close lid, and come by the component of work station Start automatically to recover spinning at work station, therefore, in the case of attempting restarting to spin unsuccessfully, call operation person.
In another modification of method, after interrupting spinning operation, deposit in the quality of yarn and the sensor of existence In the case of yarn, by the program of control unit to for making the component of the cover of spinning unit ground wing drop provide Order, and will be drawn in low-pressure channel from the yarn of the cylinder of temporary storing device oppositely unwinding, therefore, by spinning Interrupt yarn at the edge of the ingate of rotor, closes lid, and starts at work station automatic by the component of work station Recover spinning, in the case of there is not yarn in the quality of yarn and the sensor of existence or in trial, restart spinning In the case of failure, call operation person.
Meanwhile, make the lid wing drop of spinning unit to fully open position by the component of work station.
In order to reliably interrupt yarn and create the yarn end that applicable spinning enters, if passing through spinning rotor, with Per minute about 15, the speed of 000 revolution (rpm) interrupts yarn, then this is by highly beneficial.
In order to improve the reliability that spinning enters and the quality improving joint, if the side of the component at relevant work station Help down, before interrupting yarn, by compressed air, spinning rotor is cleaned, then this is by highly beneficial.
The electric current of the electromotor of the individual drive of the spinning rotor being integrated in magnetic bearing by monitoring is inputted, permissible On the basis of this input falls sharply, detect yarn breakage, and at relevant work station, stop spinning according to timely mode, and, Similarly, in this case, the rotation of temporary storing device is made by combining other actuator at station of synchronizing to quit work The operation snap back of cylinder, it is possible to achieve state when yarn end is maintained in spinning unit, hence in so that can carry out The automatic spinning performed by the component of the work station of machine enters.Alternatively, for detection of broken, it is also possible to monitor in spinning single Subtracting of the torque of the driving means of the reduction of the yarn tension in the exit of unit and/or the cylinder of drum-type temporary storing device Little.Natural, can be in conjunction with all methods of timely detection of broken.
In order to show yarn breakage between rotation compensation arm and the wind of temporary storing device, by work station Control unit monitors the torque of the rotation compensation arm of temporary storing device, and, in the case of value is the least, interrupt accordingly Spinning at work station and call operation person.
