Description

textile machine

The invention relates to a textile machine, in particular winding machine, with a plurality of jobs with functional means for carrying out operating functions, means for monitoring the production process during production and means which are adapted to determine a deviation from a desired production process.

EP 0 685 580 B1 discloses a generic textile machine designed to detect production-related causes of defects in yarns, rovings and ribbons. In a first step, defects in the product are detected with a sensor that is part of a yarn cleaning system, for example. The measured values are compared with one or more thresholds and sorted into a classifier field. The classification field results in an error pattern that can be compared with predetermined model reference patterns that indicate causes for the detected errors. The solution disclosed in EP 0 685 580 B1 is based on a statistical evaluation of measured values recorded during production. In this way, however, not all error causes can be determined by far. On the other hand, a certain amount of time has to be produced incorrectly in order to determine a cause of the error.

DE 39 17 055 AI discloses a device for monitoring the yarn-spool production process of the winding device of a cheese-producing textile machine. Here, the product is not monitored in order to determine causes of errors, but production parameters are evaluated; in the present case, the traversing amplitude and / or the traversing frequency are monitored. However, only certain causes of errors can do so be recognized, for example, a thread tensioner or drum malfunction.

DE 40 31 419 AI discloses a textile machine, in particular winding machine, with a variety of jobs with

Functional means for carrying out operating functions, wherein the workstations assigned to a common central control unit having control and display means. The

DE 40 31 419 AI discloses a winder with several juxtaposed winding units. If the textile machine or its control unit detects an abnormal condition, this is displayed to the operator. For error analysis, the operator can manually activate a slow test run of the job and visually monitor it. In this way, the operator can determine a possible cause of failure based on his expertise or check the proper functioning of the textile machine as part of a maintenance. At the control of the textile machine required maintenance and the associated maintenance intervals can be entered. Furthermore, the work performed on the controller can be entered. In this way, it can be easily checked if and when certain work is to be performed. During such maintenance work, for example, functional checks are carried out by visual inspection, functional elements are cleaned, moving parts are lubricated or functional elements are replaced preventively.

DE 602 19 260 T2 discloses a winding machine in which each winding unit can be checked individually, in particular by visual inspection. To do this, the operator on the machine control must activate a test mode and test it

Specify jobs. Then the operator goes to the respective workstation and activates a validity / invalidity Switch. The operator can then carry out the inspection directly at the workplace.

For the work described in DE 40 31 419 AI or DE 602 19 260 T2 is always highly qualified personnel with precise knowledge of the respective textile machine required. In addition, visual checks or individual checks at each job in a variety of jobs are quite complex and time-consuming.

The non-prepublished DE 10 2010 034 971 AI is based on a textile machine according to DE 40 31 419 AI, in particular winding machine, with a variety of jobs with functional means for carrying out operating functions, wherein the jobs a common central control unit is assigned, the control and display means having. In order to simplify the troubleshooting and the implementation of maintenance on textile machines, processes for the automatic checking of functional means are executable at a job, in a production interruption by means of the control means of the central control unit predetermined procedures for automatically checking at least one functional means of a job can be triggered. Means are provided for transmitting the result to the central control unit, and the result of the check can be read on the display means of the central control unit.

Through this solution, the review is almost carried out at the touch of a button. The intelligence to assess the verification is implemented in the central control unit of the textile machine. The operator can read the result directly and thus receives an instruction to act. For example, it may be indicated that a particular functional agent is dirty and needs to be cleaned or a functional agent is no longer correct works and needs to be replaced. Since the intelligence is implemented in the machine, work can be easily performed by trained personnel. However, the invention also gives qualified personnel the opportunity to carry out the maintenance and troubleshooting faster and more efficiently. The check can be carried out completely from the central control unit. The paths to jobs are eliminated.

According to one embodiment, the workstations to be checked can be predetermined by means of the operating means. It can all

Workplaces of the textile machine to be specified for review. But it is also possible to check only a part of the jobs. This makes sense, for example, if this part of the jobs is at a standstill and continues to be produced on the others. It is also possible to specifically check jobs that have shown abnormalities during production.

The verification of the specified jobs can be triggered simultaneously by means of the operating means. This means that the automatic check of the given jobs takes place in parallel. In this way, fast and efficient maintenance can be ensured.

According to another embodiment disclosed in DE 10 2010 034 971 AI, predetermined sequences for automatically checking a plurality of functional means of a workstation can be triggered by means of the operating means. This simplifies, in particular for less qualified personnel, the review, as quasi with the press of a button more functional means can be checked. The operator does not necessarily have to select the functional means assigned to these processes himself. The triggered processes can trigger an overall check or even check only a part of the functional means. The at least one functional means to be checked can be predetermined by means of the operating means. For an individual review is possible.

Advantageously, functional groups of the workplace are assigned to functional groups and a functional group can be selected for checking. Such an option will be used by the operator, especially if there is something unusual about this function group due to production. These abnormalities can be displayed by the central control unit due to the automatic evaluation of the production data or recognized by the expert observation of the operator.

The result of the check can be displayed on the display means as text. That is, a delimited coherent utterance is provided in written language. Such a presentation gives an immediately understandable information. It is not necessary to look up the meaning of a signal or code in a manual.

With the solution of DE 10 2010 034 971 AI satisfactory results can be achieved for maintenance purposes. In case of abnormalities and errors during the production process, it offers the non-expert operator but very limited assistance. Even if the deviation that occurs during production is displayed, it is the sole responsibility of the operator to relate the deviation to individual functional agents and to test them specifically. The execution of the error analysis is therefore based on the expertise of the operator. The non-expert operator thus only has the possibilities outside the normal maintenance intervals to carry out a test run of all functional means. That does not mean one insignificant amount of time. During this time can not be produced, so that the productivity is reduced.

Starting from a textile machine, as in the

EP 0 685 580 B1 is disclosed and in which means for monitoring the production process during production and means for determining a deviation from a desired production course are present, the present invention is based on the object, the detection of errors, caused by the deviations in the production process to improve and to allow a fast and as accurate as possible determination of the causes of deviations of the production process from the desired course.

The object is achieved by the characterizing features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

To solve the problem, processes for automatically checking functional agents can be carried out at a workstation and means are designed to trigger predetermined sequences for automatically checking at least one functional agent of a workstation during a production interruption, depending on the deviations determined, wherein display means and means for transmitting the Results of the review to the display means are present to represent the result of the review on the display means.

In the textile machine according to the invention, a check is automatically initiated when a deviation of the production process from a desired production process occurs. The procedure for checking depends on the type of deviation. That is, it will be checked specifically functional means that are related to the deviation could. The result can be displayed to the operator and is available to him quickly and without loss of productivity.

The check is performed during a production interruption. This production interruption can be initiated selectively, or it can be maintained until the next regular production interruption. The procedure can be made dependent on the type of deviation. In the case of a serious deviation, which would result, for example, in a rejection of the product produced, production is interrupted anyway. If necessary, a check by the machine can be triggered immediately and a result is immediately available to the operator. The error can be detected so quickly. For less critical deviations, the check will be triggered at the next production stop. Such production interruptions occur in a winding machine, for example, in a yarn break or a cop change. Thus, there is no negative impact on productivity.

In principle, it is possible to detect all types of errors by means of processes specially initiated for checking purposes.

Compared to a purely static evaluation of the production process, the possibilities of detecting the cause of the defect are in any case significantly expanded.

The display means may be part of a central control unit common to the workplaces. In this case, only one display means is required for all jobs. But there may also be display means at each workstation. In this case, the result is easier to assign to a job.

For the presentation of the result, there are various possibilities possibilities, which may be used alternatively or in conjunction with each other.

The result of the check may include an instruction to correct the deviation. Such a result particularly supports the less skilled operator. The instruction may consist, for example, in the request to exchange a specific functional agent.

The result of the check may also include an indication of the cause of the deviation. In this way, the expert receives a precise indication without having to act on his own. The appropriate action is up to his decision.

In the event that the cause of the error can not be broken down to a specific functional means and by means of the automated procedure only one group of functional agents can be identified as the cause or a more precise one

Error analysis in an automated manner is too expensive, the result of the check may include an instruction to more accurately determine the cause of the deviation.

The means for monitoring the production process according to the present invention may include means for monitoring the quality of the processed product. Such agents are known in the art in principle and, for example, in the generic EP 0 685 580 Bl discloses.

However, it is also possible in connection with the invention that the means for monitoring the production process include means for monitoring the production parameters, such as

Example in the cited DE 39 17 055 AI.

According to a preferred embodiment, the textile machine according to the invention comprises means for comparing the production process of several jobs. Such means are preferably part of a central control unit and give the possibility to define a desired production process. For example, the desired production process can result from an average of the same sizes of several or all workstations on which the same product is manufactured.

Alternatively, it is also possible that the operator

specifies the desired production process.

The invention will be explained in more detail with reference to an embodiment shown in the drawings.

Employment;

FIG. 2 shows a workstation of a textile machine according to the invention; FIG.

4 shows a schematic structure of a control device

a job. Fig. 1 shows a winding machine 1 with a plurality of winding units 2, which are arranged between the end frames 55, 56 of the winder 1. The winding machine has a central control unit 50, which is connected via a bus system 60 to the control devices 40 of the winding units 2. The central control unit has a keyboard 52 and a display 51 for operation and display.

In Fig. 1, a winding unit 2 is shown schematically in side view during the winding process. On these winding units 2, as is well known and therefore not explained in more detail, supply bobbins, generally produced on ring spinning machines spinning cops 9, which have relatively little yarn material, rewound to large-volume cheeses 11. The finished cheeses 11 are then transferred by means of an automatically operating service unit 57, such as a cheese changer, on a machine-spooled cross-bobbin transport device 21 and transported to a machine loading side arranged Spulenverladestation or the like.

Such winding machines 1 are also equipped either with a round magazine, can be stored in the spinning cops, or the automatic packages have a logistics device in the form of a bobbin and tube transport system 3. In such a bobbin and tube transport system 3 then run spinning cops 9 and empty tubes 34, which are arranged in a vertical orientation on transport plates 8. Of this sleeve transport system 3, only the Kopszuführstrecke 4, the reversible drivable storage section 5, one of the leading to the winding units 2 transverse transport sections 6 and the sleeve return path 7 are shown. As indicated, the delivered spinning cops 9 are thereby initially in an unwinding position 10, which in the region of the transverse transport sections 6 at the winding units 2, positioned and then rewound.

For this purpose, the individual workstations 2 have, as is known and therefore only indicated, various thread monitoring and treatment devices, which not only ensure that the spinning cops 9 can be rewound into large-volume cheeses 11, but also ensure that the During the rewinding process, thread 30 is monitored for thread defects and detected thread defects are cleared out. Each work station 2 has a control device 40, which is connected to the thread monitoring and treatment devices via the control lines only indicated, and is connected via the bus system 60 to the central control unit 50 and the control device 58 of the service unit 57.

For example, the work stations 2 each have a winding device 24, which has a creel 18, which is movably mounted about a pivot axis 19, and is equipped with a bobbin drive device 26 and a thread-switching device 28. The creel 18 supports the cross wound coil 11 to be wound up and has a sensor 44 which detects the speed of the cheese.

In the illustrated embodiment, the cross-coil 11 is located during the winding process with its surface on a drive roller 26 and is driven by this frictional engagement. The drive roller 26 is acted upon by a speed-controllable, reversible (not shown) drive means. The drive roller 26 is operatively connected to a sensor 45 which detects the rotational speed of the drive roller. The traversing of the thread 30 during emergence onto the cross-wound bobbin 11 takes place by means of a thread-changing device 28, which has a finger thread guide 29 in the present exemplary embodiment. The winding unit 2 further has a thread connecting device, preferably a pneumatically operated

Splicing device 13 with a cutting device 43, a lower thread sensor 22, a residual thread scissors 49, a thread tensioner 14, which is in operative connection with the yarn tension sensor 46, a thread cleaner 15 with a thread cutting device 17, an upper thread sensor 20 and a paraffining device 16th

In addition, the winding unit 2 is equipped with a suction nozzle 12 and a gripper tube 25, both defined with

Negative pressure can be acted upon. The suction nozzle 12 and the gripper tube 25 are connected to a machine-length vacuum crossbar 32, which in turn is in communication with a vacuum source 33.

In the illustrated embodiment, also in the area of the paraffining device 16, a thread catching nozzle 23, which is offset somewhat rearwardly with respect to the thread running path, is positioned so that the thread 30 runs in front of its mouth 42 during the winding process. The thread-catching nozzle 23 is likewise connected to the vacuum cross-member 32 via an air switch 27. The air switch 27 in this case has a connecting piece 35 for the first thread catching nozzle 23 and a relatively voluminous discharge port 36, the mouth of which is hermetically sealed during the regular winding operation by the suction nozzle P positioned in the waiting position P. An opening of the discharge nozzle 36 by pivoting the suction nozzle 12 ensures that the upcoming at the thread catching nozzle 23 negative pressure collapses.

In the present embodiment is in the operating menu of the central control unit 50, which on the display 51 at a Production interruption of all or part of the winding units is displayed, an item Offline review exists. If the offline check is selected, a submenu appears. This allows the operator to select the winding units to be checked. Furthermore, it can be selected that all test sequences connected with the offline check are to be carried out, it is possible to select a function means or several function means or it is possible to specify function groups whose function means are to be checked. After the selection has been made, the check can be triggered. Several selected winding units 2 are then checked in parallel.

In the following, only a few possible test sequences, with which individual functional means can be checked, are described by way of example.

For functional testing of the thread-catching nozzle 23, this is presented to the upper thread. For this purpose, the suction nozzle 12 pivots from its waiting position P in the direction of the cheese 11 and detects the accumulated on the cheese 11 after the Spulunterbrechung thread and then pivots back to the waiting position P. In this case, the suction nozzle 12 sets the thread in the cleaner 15 and in the thread connecting device 13 a. The cleaner 15 first detects the correct presentation of the thread. As soon as the suction nozzle 12 has reached its waiting position P again, the previously opened relief nozzle 36 is closed again and the thread-trapping nozzle 23 is subjected to negative pressure. The thread is then cut by the thread cutting device 17 of the thread cleaner 15 or by the cutting device 43 of the thread connecting device 13. The cut thread is sucked by the suction nozzle 12. It depends on the functionality of the thread catching nozzle 23, which happens with the free end of the thread wound on the cross wound bobbin. If the thread catching nozzle in order is, the free end of the thread is absorbed by this. The thread is then no longer in the cleaner 15. The cleaner 15 detects the absence of the yarn. The signals are evaluated in the control device 40, which has also controlled the presentation of the thread. If the thread catching nozzle 23 is not in order, the thread is not sucked in and remains in the cleaner 15. The presence of the thread is detected by the cleaner 15. The control device 40, which evaluates the signal of the cleaner 15, detects the error. The procedure for checking the thread catching nozzle is already out of the not previously published

DE 10 2009 058 827 AI known and described in more detail. In the cited application, however, the process is performed cyclically and not as manually triggered at the central control unit 50 verification of jobs. The result of checking the thread catching nozzles 23 of the selected winding units is passed on to the central control unit 50 via the bus system 60 in accordance with the present invention.

The winding device 24 has a lifting cylinder, not shown, which lifts the creel 18 with the cheese 11 from the drive roller 26 as needed. For checking a lift-off process is automatically initiated and the speed of the driven drive roller 26 compared with the speed of the cheese 11.

Further, 24 mechanical brakes are present on the winding device, which slow down the cheese 11 after lifting to a standstill. By measuring the braking time, the control unit 40, 50 can close the brake wear.

The drive roller 26 is driven by a drum motor, not shown. To check the drum motor lubrication, the motor can be driven with the cheese 11 lifted with a constant current, which corresponds to a constant drive torque. be charged. Then, the acceleration of the motor and the drive roller 26 is measured. That is, the time is measured until a predetermined speed is reached. If the acceleration is too low, a drum motor lubrication is necessary. Alternatively, the torque required to hold the drive roller at a predetermined speed can be detected. The moment is proportional to the motor current. The measurement principle corresponds to the method which is used according to DE 10 2007 062 631 AI for the detection of a thread winding on the drive roller.

The upper thread sensor 20 and the lower thread sensor 22 can be checked in a production interruption, that is, without thread, by a reference measurement. If the measured value deviates from the reference value, contamination of the sensors can be deduced.

The results of all test procedures can be transmitted to the central control unit 50. Here, in principle, each check with the associated status can be displayed. That is, it is also displayed if the check did not result in an error. However, it is useful, especially when operating by less qualified personnel, to display only the error messages directly, otherwise due to the large number of jobs too much data flood arises that the operator can not even record. Text messages can then be displayed on the display 51 of the central control unit 50, such as "winding station 17: thread-catching nozzle blocked" or "winding station 46: upper-threading sensor dirty". However, all status messages can also be stored in a log file which the expert operator can also display on the display 51 of the central control unit 50 at a later time. The function of a textile machine according to the invention will be explained below with reference to two examples. The additional compared to the prior art control and evaluation means are shown schematically in Figs. 3 and 4, wherein the Fig. 3 refers to the central control unit 50 and Fig. 4 refers to the control device 40 a winding unit. 2

Cheese coils 11 can be wound, for example, to length. That is, a cheese change is initiated as soon as a predetermined length of thread is wound on the cheese. In the illustrated embodiment, the thread length is determined by means of the rotational speed of the drive roller 26, which by means of

Sensor 45 is measured. In addition to the thread length, the diameter of the cross-wound bobbin 11 can be monitored. For this purpose, not only the rotational speed of the drive roller 26 is measured, but it is also the speed of the cheese 11 monitored by the sensor 44. From the known diameter of the drive roller 26 and the ratio of the two speeds can be determined during production, the diameter of the cheese.

In addition to the keyboard 52 and the display 51, the central control unit 50 has a processor 53 which performs the control tasks of the central control unit and coordinates the data exchange with the bus system 60. The processor 53 has means 59 for comparing the production process of several jobs. That is, production parameters or quality data of various jobs can be compared. In the present embodiment, the diameters of the cheeses are compared. That is, it is calculated an average value of the diameter over all winding units of a batch and compared with the individual diameters of the cheeses. The mean value thus defines the desired production process. If a cross-coil diameter deviates from the mean, this indicates a malfunction of a functional agent of the working close. According to the embodiment of the present invention, the central control unit has means 54 for determining the deviation from a desired production course, that is, for determining the deviation of the cheese diameter from the mean value.

The described deviation of the cheese diameter can have various reasons. On the one hand, the density of the faulty cross-wound bobbin could deviate. The density of the coil is essentially determined by the thread tension during winding. The correct thread tension is ensured in the case of the winding machine shown in FIG. 1 by the combination of thread tensioner 14 and thread tension sensor 46. It is also possible that the determination of the length is erroneous. The reason for this may lie in an error of the sensor 45, which measures the rotational speed of the drive roller 26. A defect of the sensor 44 would lead to an error in the determination of the diameter.

In order to trigger and monitor the processes described below for checking, the control device 40 of the winding unit 2 has a processor 41.

If a diameter deviation of a finished cheese 11 is determined, a production interruption is anyway required to replace the finished cheese 11 against an empty sleeve. Then, processes for checking the functional means explained above are automatically initiated by means of the processor 41. First, by means of the handling devices of the winding station, a thread is arranged in the thread run such that a thread tension or a thread tensile force can be exerted on the thread by means of the thread tensioner 14 and that the thread tension can be detected by means of the thread tension sensor 46. When the thread is stationary, a defined thread tension is now generated by means of the thread tensioner 14 and by means of the Yarn tension sensor 46 measured. Since other influences are avoided as far as possible in the described sequence, a deviation indicates a defect in the system of yarn tension sensor 46 and thread tensioner 14. For example, the result displayed could be: "Yarn tension sensor and

Check the thread tensioner! "The result could also be:

"Yarn tension sensor a thread with defined weight

"If the operator executes the latter instruction, the error could still be circled further because the yarn tension sensor 46 can be tested independently of the thread tensioner.

To check the sensor 45, the cross-wound bobbin is lifted off the drive roller 26 and the motor of the drive roller 26 is operated at a defined operating point. If the measured speed deviates from the expected one, this can be reduced to one

Close the error. The ad could be for example:

"Check the speed of the drive drum." Or:

"Change the speed sensor drive drum."

The sensor 44 can be similarly checked by driving an empty shell from the drive roller 26.

In the second example, the thread cleaner 15 and the evaluation device 47 of the control device 40 of the winding unit 2 are used to determine a deviation from a desired production profile. By means of the thread cleaner 15 imperfections are usually determined in the winder that arise in the upstream spinning process and are removed during the winding process by a cleaner cut. Such

Imperfections can be, for example, thick spots, thin spots or foreign fibers. The measuring signals of the thread-clearing device 15 are output by the evaluation device 47 of the control device 40. evaluates and compares them with suitable predetermined limits.

However, problems can also occur during the winding process, which can be detected by means of the thread cleaner 15 and the evaluation device 47. Thus, by means of the evaluation device 47, which evaluates the signals of the thread cleaner 15, trailing threads and yarn loops can be detected. However, a distinction between the two events from the signals of the fiber cleaner 15 is difficult. In both events several threads are detected in the measuring slot of the thread cleaner.

Yarn loops can be mainly due to a malfunction of the

Sling brake 48 arise. The loop brake 48 is arranged in the yarn path in the vicinity of the cop station located in Abspulstellung 10 9 and to prevent the coil

Yarn loops are deducted from the cop 9.

Trailing threads result from errors in the remaining thread scissors 49. The remaining thread scissors 49, which is basically active at the beginning of each head change circuit, prevents dragging threads from forming in the event of an unsuccessful splicing operation.

At this point, the present invention begins. If the evaluation device 47 has determined the above-explained deviations from the desired production profile, a check of the remaining thread scissors 49 and the loop brake 48 is triggered by the processor 41 of the control device 40.

In order to check the loop brake 48, the lower thread, that is, the thread coming from the cop, is picked up and held by the hook tube 25 during a production interruption. The gripper tube 25 places the lower thread in the lower thread sensor 22 on. During these operations, the loop brake 48 is deactivated. Then the loop brake 48 is activated, that is, the lever of the loop brake 48 is placed on the cop. As a result, the quiescent thread is pulled tight. The short movement during tightening can be detected by the lower thread sensor 22. If the bobbin sensor 22 detects no change in the activation of the loop brake 48, an error of the loop brake 48 can be concluded. Thereafter, the remaining thread scissors 49 is activated, which is arranged directly under the lower thread sensor 22. With the correct function of the remaining thread scissors 49, the thread is separated and the thread is sucked in above the remaining thread scissors 49 from the hook tube. There is no longer any thread in the lower thread sensor. This change can be detected by the lower thread sensor 49 accordingly. If the signal of the lower thread sensor does not change, there is a malfunction of the remaining thread scissors 49.
