JP6120654B2 - Method for operating a winder and winder - Google Patents

Description

  The present invention is a method of operating a winder having a large number of working units, wherein each one sensor in each of a plurality of working units detects one operating parameter of each working unit, The present invention relates to a method for operating a winder, which prepares sensor signals for reproducing operating parameters and generates a control signal for an actuator that affects the operation of each working unit in relation to the sensor signals. The invention also relates to a winder implementing the method.

  Winders with a large number of working parts have long been known in the prior art. Such a winder rewinds the yarn from a feed bobbin, which is at least one spinning cup, into a winding package, which is at least one traverse package. A series of sensors and actuators are arranged in the working unit, and these sensors and actuators enable independent operation of each working unit. If one sensor of a working unit fails, controlled operation of the working unit is usually no longer possible. In such a case, the working part is stopped and production is suspended until the defect is eliminated by the operator. In the prior art, it has also been considered that the operation of the working unit is continued with the failed sensor as it is. However, this has the risk of reducing the quality of the twill roll package.

  An important sensor for the quality of the wound winding package is the yarn tension sensor. In connection with the yarn tensioner, the yarn tension can be kept at a desired value throughout the package forming process (Spulenreise), thus ensuring the quality of the twill package. As described in the specification introduction part of DE 3733591 A1, the thread tension increases continuously when the take-up speed remains the same when the cup is fed out. In other words, the yarn tension increases as the residual yarn length in the spinning cup decreases unless other effects are exerted. Such an increase in yarn tension can be adjusted using a yarn tensioner controlled by a yarn tension sensor. As further disclosed in DE 3733591 A1, the yarn tension is influenced by the winding speed. For this reason, it is also possible to adjust the yarn tension that rises when the residual yarn amount decreases by decreasing the winding speed.

  Preferably both methods are combined, i.e., in order to keep the yarn tension constant, first the yarn tensioner is further opened. If the yarn tensioner is fully open and it is no longer possible to further reduce the yarn tension using the yarn tensioner, the winding speed is reduced.

  Japanese Patent Application Laid-Open No. 2009-242096 discloses a winder having a large number of working units. Each of these working parts is provided with one yarn tension sensor and one yarn tensioner. A control signal for the thread tensioner of each working unit is generated in association with the signal of the thread tension sensor. In this known configuration, the measured value of the yarn tension sensor of one working part is stored, and when the yarn tension sensor fails, the yarn tension is controlled based on the last stored tension value before the failure. Has been proposed. Alternatively, in order to control the yarn tension in the working part where the failure has occurred, it is also possible to use the average value of the measured values detected in the other working parts before the failure. That is, in this way, the winder can be operated even when one sensor fails.

  However, the tension measurement used to control the yarn tension is not the same as the last value of the other working part or the average value is used, the tension sensor supplies a new measurement value. Unless otherwise, it remains constant. That is, the known method is not suitable for long-lasting failures that cannot be resolved immediately. This is especially true because the effect caused by the feeding of the cup is adjusted completely or partly by the yarn tension control device in a properly functioning sensor. This is no longer possible with constant value control. Eventually, the quality of the twill package will be adversely affected.

  In many winders, a sensor for detecting the number of rotations of the traverse package is arranged on the package frame of the working unit. The twill package is driven by friction by the drum. For example, when accelerating or braking after thread breakage or clearer cutting, the rotational speed of the traverse package is changed in stages. This greatly prevents large slips, for example, the difference between the peripheral speed of the drum and the peripheral speed of the winding package. Slip can cause friction at the package surface, which can damage the twill package. The upper yarn layer can slip off, adversely affecting the quality of the twill package. For acceleration, the rotational speed of the driven drum is increased in stages and the rotational speed of the traverse package is monitored. If the traverse package remains constant, the acceleration process ends and the traverse package rotates with the drum without slipping. The drum speed is then increased by one step and the process is repeated accordingly until a final speed is obtained. Braking is performed in the same way. In the event of a failure of the speed sensor, the traverse package must be braked or stopped uncontrolled. Controlled activation of the traverse package is no longer possible. The working part remains stopped until the defect is resolved by the operator.

DE3733351A1 JP2009-242096

  Therefore, an object of the present invention is to provide a possibility that the operation of the working unit at the time of the failure of the sensor can be continued without impairing the quality of the winding package.

  This problem is solved by the method according to the characterizing part of claim 1 and the winder according to claim 10. Preferred variants of the invention are described in the dependent claims.

  In order to solve the above problems, in the method of the present invention, in the method of operating the winder described at the beginning, the first working part of the plurality of working parts is out of the plurality of working parts. When the second working unit is selected and the sensor of the first working unit among the plurality of working units fails, the control signal for the actuator of the first working unit is sent to the second working unit. In relation to the sensor signal prepared by the sensor of the working part, in which case the second working part is associated with the first working part during the failure of the sensor of the first working part with respect to the operating parameters. It is in an equivalent state.

  That is, in the method of the present invention, the sensor of the second working unit is used instead of the sensor that has failed in the first working unit. The sensor of this second working part certainly does the measurement continuously in the second working part, not in the first working part, however, the second working part is related to the operating parameters measured by the sensor. Since it is in the same state as the first working unit, that is, at a level that does not cause a problem in control technology, the sensor provides an equivalent value. In this way, not only is the operation of the working part with the failed sensor maintained, but also the quality of the finished winding package is ensured, since appropriate alternative values can be used by the method according to the invention.

  In many cases, all working parts of one winder are formed in the same way, so that all working parts also have respective sensors. In this case, in principle, any working unit can be used as the first working unit or the second working unit when the other conditions described above are satisfied. Further, it is possible to adopt a configuration in which the winder includes various working units and a specific sensor is provided only in a part of the working unit. In such a case, the method according to the invention applies only to the relevant part of the working part for this sensor.

  The state of the working part can be described, for example, by one or more state variables, in which case the state variables influence the operating parameters.

  Preferably, the second working part is selected in terms of operating parameters in relation to the state of the first working part. This determination can be made in some cases already before the failure of the sensor. For this purpose, the states of the plurality of working units are continuously detected with respect to the operating parameters, and an appropriate second working unit is selected for each working unit. However, when the second working unit is selected for the first time when a failure occurs, it is preferable to continuously detect the states of the plurality of working units with respect to the operating parameters. If it does in this way, at the time of failure of the sensor of the 1st operation part, the 2nd operation part can be determined quickly, and the operation without interruption of the 1st operation part is guaranteed. The continuously detected state can be detected and stored by the control device of the individual working units and can be exchanged quickly via a suitable data transmission means, for example a bus system. Alternatively, continuously detected states can be detected and stored by one central control unit.

  In a particularly preferred aspect, the second working part is such that at the time of the sensor failure, the state of the first working part and the state of the second working part are at least partly equivalent with respect to the operating parameters. Select. That is, the second operation is performed so that the state of the first working unit and the state of the second working unit are at least partially equivalent with respect to the operating parameters before the occurrence of the failure or at the time of occurrence of the failure at the latest. Select the part. In certain cases, such a partial match is already sufficient in order to utilize the appropriate sensor signal of the second working part for the first working part. When a state is described by multiple state variables, partial equivalence exists when some of the state variables are equivalent.

  In a preferred embodiment, the second working unit is selected so that the state of the first working unit and the state of the second working unit are the same with respect to the operating parameters at the time of occurrence of the sensor failure. Even in this case, the second working unit is set so that the state of the first working unit and the state of the second working unit are the same with respect to the operating parameters before the occurrence of the failure or at the latest when the failure occurs. Select. If perfect equivalence exists at the time of the sensor failure, this equivalency is maintained throughout the failure, and the sensor of the second working part has an appropriate value for the first working part. It can be assumed that it is provided. Full equivalence is obtained when all state variables describing the state with respect to operating parameters are equivalent.

  If sufficient equivalence between the state of the first working unit and the state of the second working unit does not exist at the time of the failure, the state of the second working unit during the failure of the sensor Is matched to the state of the first working part. This method can be used when a partial match of state already exists. However, it is also possible to determine any one working part of the plurality of working parts as the second working part and then make a suitable adaptation of the state.

  The method according to the invention can be used, for example, when a single thread is wound up from a spinning cup onto a winding package in a plurality of working parts and the sensor is formed as a thread tension sensor. The state of the first working part and the state of the second working part, which must be equivalent with respect to the operating parameter “yarn tension”, are equivalent in the residual yarn length in the spinning cup.

  The method according to the invention likewise applies to the above-mentioned second example, i.e., in each of a plurality of working parts, one thread is wound around a winding package, which is wound by a rotatable drum. Driven by friction, the sensor can also be used for the second example, which is designed to measure the rotational speed of the traverse package. In this case, when the diameter of the winding package of the first working unit is the same as the diameter of the winding package of the second working unit, the partial equivalence of the state is the first working unit and the second working unit. It exists with respect to the operation parameter “number of turns of the traverse package” of the working unit. In order to be able to use the signal of the sensor of the second working part in the event of a failure of the sensor of the first working part, the winding package of the first working part is accelerated or braked. In this case, it is possible to adjust the rotational speed of the drums of the first and second working parts in relation to the rotational speed of the winding package measured by the sensor of the second working part.

  In order to solve the above-mentioned problems, a winder for carrying out the method according to the present invention is further proposed.

  In the winding machine according to the present invention, each of the plurality of working units of the winding machine detects one operation parameter of each working unit, and one actuator that affects the operation of each working unit, And the sensor is configured to prepare a sensor signal that reproduces the operating parameter, the winder has control means, and the control means is for the actuator of each working unit. Data transmission means for transmitting the sensor signal to the control means, and data for transmitting the control signal to the actuator. In the winder provided with a transmission unit, the control unit is configured to have a second working unit out of the plurality of working units with respect to the first working unit out of the plurality of working units. A control signal for the actuator of the first working unit is selected from among the plurality of working units during the failure of the sensor of the first working unit of the plurality of working units. In connection with a sensor signal prepared by the sensor of the second working part, wherein the second working part is related to the operating parameters in the sensor of the first working part. During the failure, the state is equivalent to that of the first working unit.

  In the aspect of the winder according to the present invention, the control means includes a work unit control device assigned to each one work unit among the plurality of work units, and a central control unit, and the work unit control device includes: The central control unit is connected to each other by another data transmission means, for example, a bus system.

  The working unit control device of the first working unit may be configured to select the second working unit. Alternatively, the central control unit may be configured to select the second working unit.

  In another possible aspect of the winder according to the present invention, the different data transmission means and the working unit control device of the second working unit send the sensor signal of the sensor of the second working unit to the first working unit. The working unit control device of the first working unit is configured to transmit the control signal for the actuator of the first working unit to the sensor of the sensor of the second working unit. It is configured to generate in relation to the signal.

  According to an alternative aspect, the working unit control device of the second working unit generates a control signal for the actuator of the first working unit in association with the sensor signal of the sensor of the second working unit. The second data transmission means is configured to transmit a control signal for the actuator of the first working unit to the working unit control device of the first working unit. . That is, a control signal for the actuator of the second working unit can be transmitted to the first working unit instead of the sensor signal. The control signal of the second working unit is used for the actuator of the first working unit.

It is a figure which shows the winding machine by this invention provided with many working parts. It is a figure which shows one working part of the winding machine by this invention.

  Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a winder 1 including a large number of working units 2, and the large number of working units 2 are arranged between end frames 55 and 56 of the winder 1. The winder 1 has a central control unit 50, and this control unit 50 is connected to the working unit control device 40 via a bus system 60. The central control unit 50 has a keyboard 52 and a display 51 for operation and display.

  FIG. 2 schematically shows working parts 2 during the rewinding process, in these working parts 2, as is well known and therefore not described in detail, a storage bobbin is usually used in a ring spinning machine. The produced spinning cup 9, which has a relatively small amount of yarn material, is rewound onto the large-capacity traverse package 11. The completed traverse package 11 is then handed over to the machine-length traverse package transport device 21 using, for example, an automatically-actuated service unit 57 which is a traverse package changer, and is arranged on the machine end side. To a package loading station or the like.

  Such a winder 1 further comprises a rotating magazine in which spinning cups can be stored, or the automatic winding winder has a replenishment device formed as a bobbin and winding tube transport device 3. In such a bobbin and winding tube transfer device 3, the spinning cup 9 or the empty tube 34 that is arranged vertically oriented on the dish-shaped transfer table 8 circulates. In the drawing, only the cup supply section 4, the reversible drivable storage section 5, the lateral transport section 6 leading to the working unit 2, and the winding pipe return section 7 are shown in the bobbin and the winding tube transport device 3. . As shown in the figure, in this case, the supplied spinning cup 9 is first positioned in the feeding unit 10 located in the working unit 2 in the region of the lateral conveyance section 6 and then rewound.

  For this purpose, each working unit 2 has a variety of yarn monitoring devices and yarn processing devices, which are not shown in the drawings because they are known, and these devices have a traverse winding with a spinning cup 9 having a large capacity. Not only ensures that the package 11 is rewound, but also ensures that the yarn 30 is monitored for yarn defects during the rewinding process and that the detected yarn defects are cleared. Each working unit 2 has a working unit control device 40, which is connected to the yarn monitoring device and the yarn processing device via a schematically illustrated control line, and is connected to the center via a bus system 60. The control unit 50 and the control device 58 of the service unit 57 are connected.

  Each of the working units 2 includes, for example, one winding device 24. The winding device 24 includes a package frame 18 that is supported so as to be movable around a pivot shaft 19, and includes a package driving device 26 and a thread twill. A shaking device 28 is provided.

  In the illustrated embodiment, the traverse package 11 has its surface in contact with the drive drum 26 during the rewinding process and is driven by the drive drum 26 by friction. In this case, the drive drum 26 is driven via a reversible drive device (not shown) whose rotation speed is adjustable. The package frame 18 is provided with a sensor 37 that detects the number of rotations of the winding package. This sensor 37 is also called a package frame sensor. In the illustrated embodiment, the yarn 30 is traversed during winding onto the traverse package 11 using a yarn traversing device 28 having a finger yarn guide 29.

  The working unit 2 further includes a yarn splicing device, preferably a pneumatically operated splicing device 13. The splicing device 13 includes a cutting device 43, a lower yarn sensor 22, a yarn tensioner 14, and a yarn cutting device 17. A yarn clearer 15, a yarn tension sensor 20, and a paraffin processing device 16 are provided.

  Further, the working unit 2 includes a suction nozzle 12 and a gripper pipe 25, and a prescribed negative pressure can be supplied to the suction nozzle 12 and the gripper pipe 25. In this case, the suction nozzle 12 and the gripper pipe 25 are connected to a negative pressure beam 32 of machine length connected to a negative pressure source 33.

  In the illustrated embodiment, a yarn gripping nozzle 23 is also positioned in the region of the paraffin processing unit 16 which is positioned somewhat rearwardly with respect to the yarn runway, so that the yarn 30 is removed during the rewinding process. It travels in front of the opening 42 of the gripping nozzle 23. The yarn gripping nozzle 23 is similarly connected to a negative pressure cross beam 32 via an air branching portion 27. In this case, the air branch portion 27 has a connection pipe piece 35 for the yarn gripping nozzle 23 and a relatively large pressure release pipe piece 36, and the opening of the pressure release pipe piece 36 is used during normal rewinding operation. The suction nozzle 12 positioned at the standby position P is hermetically closed. The negative pressure in the yarn gripping nozzle 23 is extinguished by opening the pressure release pipe piece 36 by the upward rotation of the suction nozzle 12.

  In a normal unwinding operation, the yarn tension is adjusted in each working part. In the illustrated embodiment, a target value for the yarn tension is preset. This target value can be preset for each lot by an operator, for example, in the central control unit 50, and transmitted to the work unit control device 40 of the work unit 2 belonging to the lot using the bus system 60. The actual value of the yarn tension is measured using the yarn tension sensor 20. Based on the deviation between the target value and the actual value, an adjustment signal for the yarn tensioner 14 is generated using an adjuster which is part of the working unit controller 40 in the illustrated embodiment. By adjusting the thread tensioner 14, the actual value of the thread tension is kept at a preset target value.

  In order to maintain a constant yarn tension, first a high tensioner pressure is required. The shorter the residual yarn length in the spinning cup, or the longer the fed-out yarn length, the lower the tensioner pressure must be adjusted in order to obtain a constant yarn tension or yarn pulling force. When the tensioner pressure is constant, the yarn pulling force increases as the length of the drawn yarn increases.

  The winding speed or rewinding speed is not constant throughout the cup feeding process (Kopsreise). If the thread tensioner 14 can no longer reduce the pressure anymore, the winding speed is reduced in steps, which again allows the thread tension to be adjusted using the thread tensioner 14.

  The quality of the yarn 30 is continuously monitored using the yarn clearer 15. When the thread clearer 15 detects an unacceptable defect in the thread 30, the cutting device 17 is activated and so-called clearer cutting is performed. Before the yarn defect is removed and the yarn end is spliced again using the splicing device 13, the traversed package 11 must be braked. Even when unintended yarn breakage occurs, the traverse package 11 must be braked accordingly. This is achieved according to the illustrated embodiment by reducing the rotational speed of the drive drum 26 in stages. In this case, the rotational speed of the traverse package 11 is continuously monitored using the package frame sensor 37. As soon as the rotational speed of the traverse package 11 becomes constant or the deviation becomes smaller, the next rotational speed stage of the drive drum 26 is introduced. This procedure or method is repeated accordingly until the traverse package 11 stops. In this way, slip that occurs during braking is kept to a minimum. After forming the spliced portion using the splicing device 13, the traverse package 11 is accelerated again. In this case, the same operation is performed, and the rotational speed of the drive drum 26 is increased stepwise. The next stage is introduced as soon as the rotational speed of the traverse package 11 no longer changes or becomes sufficiently small. The rotational speed of the drive drum 26 is increased at a preset stage until a desired rotational speed is obtained.

  In the following, the method according to the invention will be described by way of example when two different sensors have failed. In this case, it is assumed that the sensor in the work unit 2A fails and the signal of the corresponding sensor in the work unit 2B is used for further operation of the work unit 2A. The working units 2A and 2B have the same structure and have a configuration corresponding to the working unit 2 shown in FIG. In order to be able to quickly determine the working part 2B with a sensor signal that can be used in place of this faulty sensor in the event of one sensor failure, the state of the working part 2 is continuously detected, It is stored in each working unit control device 40. In this way, when the work unit 2A fails, information can be quickly exchanged via the bus system 60, and a suitable work unit 2B can be determined.

  First, it is assumed that the yarn tension sensor 20 of the working unit 2A fails. The yarn tension sensor 20 measures the tension of the yarn, that is, the yarn tension. The states of the plurality of working units 2 regarding the yarn tension are the same when the remaining yarn lengths of the spinning cups are the same. The residual yarn length in the spinning cup is continuously detected. The residual yarn length can be detected by the known total yarn length in the spinning cup and the fed yarn length. In this case, the fed yarn length is obtained from, for example, the number of revolutions of the winding drum. Can do. The working unit 2B preferably has a residual yarn length equivalent to that of the working unit 2A in the spinning cup. A signal from the yarn tension sensor 20 of the working unit 2B is transmitted to the working unit control device 40 of the working unit 2A. The working unit control device 40 generates a signal for the yarn tensioner 14 of the working unit 2A from the transmitted signal. Alternatively, the control signal of the working unit 2B can be used for the yarn tensioner 14 of the working unit 2A. Further, an instruction for the winding speed of the working unit 2A is generated based on the signal of the yarn tension sensor 20 of the working unit 2B and the position of the yarn tensioner 14 of the working unit 2A. The winding speed determined in this way can be adjusted via the rotational speed of the drive drum 26.

  In other situations, the package frame sensor 37 of the working unit 2A fails. In such a case, it is no longer possible to reliably brake or accelerate the traverse package 11. How the traverse package 11 responds to changes in the rotational speed of the drive drum 26 is mainly related to the diameter of the traverse package 11. Accordingly, the diameter of the traverse package 11 is continuously monitored and stored in all the working units 2. For example, the diameter can be obtained from the ratio between the rotational speed of the drive drum 26 and the rotational speed of the traverse package 11. It is desirable that the traverse package 11 of the working unit 2B has substantially the same diameter as the traverse package 11 of the working unit 2A at the time of failure of the package frame sensor 37 of the working unit 2A. If the traversing package 11 has to be braked in the working part 2A on the basis of the yarn interruption and then accelerated again, the working part 2B also causes a yarn interruption at the same time. This can be done, for example, by actuating the cutting device 17 in the working unit 2B. The processes of braking, piecing and reacceleration can be performed in parallel in the working unit 2A and the working unit 2B. In this case, the signal of the package frame sensor 37 of the working unit 2B can be transmitted to the working unit control device 40 of the working unit 2A, and is used for controlling the drive drum 26 of the working unit 2A.

  Furthermore, it is known that the winding speed decreases as the residual yarn length in the spinning cup decreases. That is, in this case, when the residual yarn length in the spinning cup 9 of the working unit 2B is significantly smaller than the residual yarn length in the spinning cup 9 of the working unit 2A, when the package frame sensor 37 of the working unit 2A fails. The package frame sensor 37 of the working unit 2B is not suitable as an alternative sensor. In such a case, both working parts 2A, 2B have different final speeds. This problem can be easily solved by exchanging the cups in both working parts 2A and 2B. In this way, the states in both working parts are again equivalent, and both working parts have equal final speeds.
