Description

[Detailed description of the invention] A method for monitoring and modifying a sequence of movements of a moving member; Bobbin winder with device for monitoring and correcting the motion sequence The object of the invention is to provide a sequence of movement of a moving member according to the preamble of claim 1. method for monitoring and correcting errors and preambles of claims 4, 9 and 1O. A motor vehicle equipped with a device for monitoring and correcting the sequence of movements of moving members involved in This relates to a winder.

The textured filament is blown into the air at high speeds (typically thousands of meters per second). It gets wound up. After the thread wound on the bobbin reaches a predetermined amount, the bobbin is Automatically rotates to the unloading position, and at the same time waits for the empty bobbin to match the unloading position. from the position to the winding position. The transition of thread running from a full bobbin to an empty bobbin is complete. This is done fully automatically and without producing any waste threads. Methods and devices that belong to the state of the art When the bobbin or empty bobbin is placed on a rotating body that is rotated for bobbin replacement. The following are known. A jig is required for the transport of the incoming thread. A thread for lifting the thread from a jig motion device A lifting device and a device for guiding the thread running towards the center of the bobbin towards the sides. from the transition area to the winding position of the new bobbin towards the full bobbin. means for lifting the running thread and a capture slot in the empty bobbin. There is a means for laterally displacing the thread through the thread. Handling of yarn (displacement, deformation) The above-mentioned mechanical movable means for performing movements such as need to be performed in a timely manner, and within a predetermined time and/or In other words, it is necessary to perform a predetermined movement at a predetermined velocity sequence. child The control signals necessary to achieve the purpose of the memory programmable control unit and at a predetermined time, this unit activates a mechanical drive to drive said means. It supplies signals to moving parts (actuators) and monitors them. to a known device If the mechanical drive reaches its end position, further control means (sensor unit) Used for monitoring of clothing.

Therefore, whether or not the execution of a certain movement has failed is determined by the fact that the drive means has not arrived at the target location. It can be determined by what was not done. As known, there are several Coordinating the mutual actuation of mechanical elements and the signals for the drives (actuators) This is to prevent the temporal sequence of movement from becoming out of order. There is a risk of collision between two or more parts that should move in unison. .

As in other methods in the field of textile industry, the problem of the quality of the yarn produced due to temporal inaccuracies in the coordination and synchronization of two mechanical parts that cause one movement. It is also triggered. Such problems occur when the rotating body does not reach a predetermined angular position. This occurs when the winding and tachometer roller ller) should occur at the correct location and time during bobbin exchange. It is something. The angular position of the rotating body determines the distance of the bobbin from the tachometer roller. Ru.

Even if the angular error of the rotating body relative to the tachometer roller is small, it will impair quality. This results in

The angular position error of the rotating body is caused by the rotating body itself (driven element) and its driving means (driving element). caused by aging, tolerances, and dust. It is something that can be done. Its continuous monitoring is essential to obtain high quality. It is something. A similar problem arises when it comes to movements that should occur in a straight line. This can occur if the elements are subject to different tolerances or are temperature dependent. Ru.

In the mechanical control unit of the known automatic bobbin winder, the driven element The movement may not have taken place at all or may not have taken place completely because it was not in position correctly. It is possible to decide that it was not done. However, the movement sequence Whether the motion was linear or non-linear process steps that are unmonitored and occur, regardless of the Changes in the temporal sequence and the resulting defects that can occur in the final product result in yarn breakage later. Therefore, it may be determined only in the processing after the bobbin or in the final product, etc. I can do it. Therefore, over long periods of time, such as minutes, hours or days, Due to slight changes in the sequence, if it is about the course, the time If the sequence is related to the sequence, a large cost disadvantage is introduced. In addition , whether the defects are acceptable for low-quality wire or cannot withstand full heat use. It is no longer even possible to decide what is wrong.

In the method and device disclosed in DE 2944219, the functionality of the processing unit is is mechanically controlled and its setting and activation in the event of a lack of dynamic balance. is possible. And the time sequence of the actual starting and stopping process is permissible. deviation from the accepted tolerance range.

This invention is intended to overcome this problem.

According to claim 1.4.9 and feature 1O, a method and method for solving this problem are provided. A bobbin winder is a mobile machine responsible for changing the bobbin in terms of course, location and/or time. It monitors and modifies the temporal combination of elements.

In the method of the invention, the mechanical errors involved in monitoring and modifying the control impulses are The instantaneous velocity and/or motion sequence for the instantaneous velocity of the element is obtained. This controls the drive of the driven element. within acceptable range The modification of the temporal combination of the movement sequence of the pneumatic drive element is By varying the temporal sequence of control impulses for the delivery This may result in an increase in friction or a set value or sequence of set values. Compensation for changes in motion path or velocity due to other effects such as motion is realized.

At the same time, the necessary response if the threshold value of the movement sequence here is exceeded. Measures, e.g. immediate stoppage of the machine, subsequent replacement of the bobbin to avoid defective bobbins This may cause the machine to stop, etc. Additionally, mark the bobbin to indicate what the defect is at that time. It is also possible to do so. Such markings mark all bobbins as defective. stratification is possible without separation.

The method of the invention is based on the actuator and sensor elements in the entire sequence. monitoring and/or control of individual sequences of movements that depend on interactions between is allowed. Although within the limits of Records manufacturing conditions such as noise, measurement tolerances, poor installation accuracy, aging effects, wear, and destruction. Moreover, it becomes possible to make corrections.

This invention acquires the deviation from the movement angle or movement length at a predetermined part. This movement and modification of the movement angle can improve the settings in subsequent work cycles. It is possible to roughly estimate the fixed value. This modification continues until the set point is obtained, and / or if a new deviation from this value occurs, a repeat is performed.

The details of this invention will be explained below with reference to Examples. Here: Figure 1 shows the bobbin winder FIG.

FIG. 9 shows a diagram of the movement position of the extension arm with respect to the intended current I. .

In the casing l of the automatic winder 3, a stepper motor or pneumatic motor There are two rotating bodies 5 that can rotate around an axis A by a drive device 4 such as a drive device. Ru. The peg 7 is rotatably held on the rotating body 5. Load the empty bobbin 9 onto peg 7. This peg 7 receives a bobbin 13 wound with the supplied thread 11.

The empty bobbin 9 is held firmly by a known clamping device 15 built into the peg 7. It is held and rotated together. The clamping device 15 is pneumatically driven. The device is connected to a lamp means drive 17.

In order to form a uniform bobbin surface and at the same time ensure the surface speed of the bobbin 13, the winding During the process, the bobbin 13 is in frictional contact with the driven tachometer roller 19. Ru. Tachometer roller 19 preferably includes electric motor 21 and tachometer roller 19 It is equipped with a tachometer 23 for determining the circumferential speed of.

The layering device 25 with thread guide means 27, which is individually assigned to the bobbin 13, It is provided above the tachometer roller 19. Layering device and its yarn guiding means 27 The drive is performed by a motor 29.

The swingable system displacement and exchange device 31 is articulated on the casing of the bobbin winder 3. , a plurality of intermediate positions from the initial position A or the idle position by the pneumatic drive device 33 It is possible to move to the change position F via positions B, C, D, and G, and the eye It is possible to return to the dollar position A.

In order to maintain a constant contact pressure of the tachometer roller 19 on the bobbin surface, the tachometer roller 19 is The meter roller 19 is held on an extension arm 35, which is connected to the bobbin. configured to be vertically movable in the vertical guide means in the casing of the winder 3 . The load on the arm 35 is provided by a pneumatic or hydraulic pressure source 38. Alternatively, it is added to the hydraulic linear drive device 37. The pressure sensor 41 is the tachometer roller 1 9, and the tachometer roller 19 is attached to the bobbin surface. Monitor contact pressure, etc. In addition to the driven element and its driving element described above. Additionally, the bobbin winder is equipped with additional parts that are not explained here. Needless to say, that function is not related to this invention.

In order to provide a detailed explanation of the first embodiment of the present invention, a system change device as a driven member will be described. 31 and the pivoting movement of the pneumatic linear drive 33 as a driving member are used here. (Figure 2).

It is connected to the linear drive 33 by a conduit 47 and is arranged in the bobbin winder 3. A solenoid valve 45 connected to an electric control unit 49 located in the 43. The movement path of the system change device 31 is monitored by the path sensor 51. Therefore, regarding the final positions A and F, if necessary, intermediate positions B, C, This is also done for D and E. Movement path monitoring is used to monitor movements between final positions A and F. additively with respect to the temporal sequence or with respect to all intermediate positions B to E You can also do that. From intermediate position B to E, the system change device 31 temporarily stops operating. These are the positions or measurement positions where the It is possible to monitor the movement route with respect to location and time. The course sensor 51 , a sensor that operates without contact and can acquire the temporary position of the system change device 31. Preferably, it is composed of an element (such as a linear potentiometer).

The course sensor 51 is connected to an evaluation circuit 53, and this evaluation circuit 53 receives the acquired measurement signal. Converts the signal value into an electrical signal. The evaluation circuit 53 is further connected to a comparison circuit 55, which The comparison circuit converts the measured value of the course sensor 51 into a set value stored in the set point device 57. Compare with. The set point device is on the other hand connected to the trigger 59. Comparison circuit 55 The results are sent to control unit 49 for further processing.

Wiring extends from the control unit 49 to the alarm unit 61, and this alarm unit is an engineering or acoustic display or switching off of the bobbin winder 3. It can be composed of a device for Additional wiring is memory 63 (Mem o) from which it extends to display the operating conditions and/or other data. It extends to a display or printer 65.

The sequence of movement of the system change device in terms of course and time is the embodiment selected therein. The position of the rotating body 5 and the diameters of the full bobbin 13 and empty bobbin 9 on the rotating body 5 in Dependent. For convenience of explanation of the movement sequence of the system change measure 31, the rotation plan of the rotating body 5 is It is assumed that the process occurs exactly as predetermined in terms of course and time. So An appropriate track/time monitoring unit can be provided for this.

In FIG. 3, a control unit 49 is used to supply compressed air to the linear drive unit 33. The (electrical) logic signal output to the pneumatic valve 45 at the precise time defined by , and the actual path of the system change device (driven element). lower side The diagram shows switch-on time 1. (set value), pneumatic valve 45 (drive element switch current for t) and switch-on time t and switch-off time t Time t! are included in the two time windows (tI@t+- and t 1w t t-). The upper diagram shows the system for course and time. It shows the course followed by the changing device 31 (drive element). At time t0, When the change from the full bobbin 13 to the empty bobbin 9 starts with the rotation of the rotating body 5, the system change The device 31 assumes an outwardly pivoted position as shown by the dashed line (FIG. 2). After time t, , pneumatic valve 45 receives commands from control unit 49. Therefore, the current The compressed air is applied to the lenoid valve and sent to the linear drive unit 33 via the piping 47. . Delays in the propagation of pressure within the pipe 47, possible expansion of the pipe 47 and/or Due to the friction between the piston and the cylinder, the system change device 31 is not activated until time t. Then, start turning clockwise. Straight line in the upper diagram of Figure 3 Assuming that the movement according to the curve K extending in occurs at a uniform speed, the driven element The client reaches the final point F of the route at time t. The time t of this movement, is important as long as no other moved element has moved into the motion path of the system changer. isn't it. This assumption holds true in this example. The important thing is the system change device 31 It is time t4 when the target F is reached. In the illustrated example, t4 is jan and t. Which within the time window between. The movement is about the course (final point F) Even in terms of time (t□-t, .), it occurs within predetermined limits and according to plan.

In the diagram shown in FIG. 4, the driven member, i.e., the thread changing device, moves at time t. but The final point F is reached a short time later. Therefore, the arrival time t4 is still This occurs between the intervening window its and Fe, and there is no need to interrupt the machine. Arrive Delays in arrival time are caused by high friction in the driving or driven elements. Therefore, the starting time t, is outside the time window il @ ile It's on the side.

t, to tl' (this point can be made more accurate by configuring it as an electronic device). (and must be located within a time window) The arrival time t4 of the driven element is set within the time window t by advancing the driven element It is possible to return to the intermediate region of x--t t- (broken line). control uni 49 places the arrival time t4 in the center of the time window t□-1ts as far as possible. Designed to maintain the same If there is a deviation, the appropriate step is to resolve the deviation. It will be held in The step size is selected in proportion to the determined deviation size (e.g. (e.g., closed-loop control with integral characteristics). Therefore, the winder operates in the optimum range and Error messages occur when the control unit is unable to make corrections large enough. This is only for critical operations such as control (limitation of control range).

Of course, the time window at the beginning of the movement cannot be expanded infinitely. . The time window must be located within the limits of to prevent the driving element from starting its movement prematurely and to ensure that the driven element protected from collisions with other elements still located within the path area of the object. I'm testifying.

The size of the window depends on various factors and is determined individually for each element. It is something that should be done. The upper and lower thresholds of this window are mechanically activated. The selection should be made to stay within the possible range. Wear on driven elements and phenomena such as damage or increased friction have a new starting point in the time window L-- t+. It can be corrected after each working cycle as long as it is located within.

In the explanation of FIG. 5, the movement of the driven element, that is, the system change device 31 is Although it starts at time t, it takes a long time due to increased friction in the linear drive section 33, etc. The end point F of the path of motion is reached only at time t4, and t4 is j am and t. is located outside the time window between reduce time t Both are corrected by time t4*-11e, but remain in time window t1w j+*. Time window type 1. − It is possible to push it back within 1ts. In this case, first stop the machine and alarm It is necessary to generate a signal and pursue the reason for the deviation.

In the embodiment of the invention shown in FIG. 6, the course sensor 51 has an initial position and a final position A and B as well as the intermediate positions C, D.

Also determine E and F. In this way, the movement of the driven member is as shown in Figures 3 to 5. whether the motion sequence occurred in a non-linear manner, It is possible to determine whether the The continuous curve Kl shown in FIG. and end point within the predefined range thresholds X and Y. . However, at one point it almost touches the lower threshold. follow Then, the driven member, that is, the system change device 31 in this case as well, is at this position (with the arrow P). (shown in Figure 1), collision with other elements, such as a bobbin that is unrolled in a rotational manner. there is a possibility. As in Fig. 4, moving the curve to the left brings the early starting point t, By selecting within the window t1wile, the start and end points are set to the initial range. It can be carried out without going outside the scope. However, this movement is extremely is possible only in a very narrow range, otherwise the control unit Then, the driven member reaches outside the time window t□-1ts. Corrections will be made.

If the curve exceeds the range threshold Y (indicated by the dashed line), then Even if the start and end points fall within their respective time windows, the control unit will not issue an alarm. Or generate a stop signal. In this case, the malfunction must be eliminated by the operator. Since it is a kimono, no modifications will be made.

The modifications to be made by the control unit 49 or those made in previous work cycles are It can be called from memory 63. Data can be displayed or printed and conclusions can be drawn about the defects of the elements that have undergone movement.

In the example above, the machine element is related to the moved element, as already explained. I assumed that it would work correctly. Like a temporal sequence of rotations of a rotating body Obtain data on additional elements or elements and, if necessary, bias It is clearly possible to correct with similar techniques when the difference falls within the tolerance limits .

In a second embodiment of the invention shown in FIG. The position of the empty bobbin 107 relative to the surface of the tachometer roller 119 and the empty bobbin 10 7 and the winding yarn 130 that has already been wound. Gap S The width must always be the same dimension within narrow limits at the beginning of the spinning process. Therefore, the contact between the bobbin surface and the tachometer roller is consistent between the two elements. In addition to obtaining a periodic rotation, this contact can be caused at a predefined time. Wear. The speed n of the bobbin 113 has a large diameter due to the thread l11 being wound. However, the gap S is filled and the outer layer of the yarn and the tachometer roller 11 are The circumferential speeds of the two elements are determined mathematically so that they are balanced even if contact with 9 occurs. It is being

Even a slight deviation β of the angle α of the rotating body 105 from the set value can cause problems in package formation. The bobbin diameter at the end will no longer match the design value. It is the diameter that is extended during bobbin formation This is because it is defined by the course of movement of the arm.

The rotation of the rotating body 105 is caused by the motor 104. A worm wheel 106 is mounted on the shaft 157 of 104 . Tsusu Muhoi The wheel 106 cooperates with the worm 108 and meshes with the rotating body 105. . In order to obtain the rotation angle of the rotating body 105, the data collection means 110 is connected to the motor 1. It can be attached to the rotating shaft of 04. One rotation of the rotating body when replacing the bobbin is equal to 180°. The 1806 rotation of the rotating body 105 is transmitted to the data collection means 110. is equivalent to, for example, 1000 pulses, and obtaining this angle of rotation of the rotating body I can do it. The drive motor is used to rotate the rotating body until the bobbin is replaced. 104 is driven until 1000 pulses are measured. Friction, bobbin mass, The drive element (motor 104) for the rotating body 105, gears, play or The drive receives a predetermined number of pulses based on the influence of the ohm wheel 106 etc. However, the rotating body 105 does not come to rest at the design time and/or at the predetermined position. is possible. For example, the actual position of the rotating body 105 may be changed to the ideal end position (angle α). On the other hand, it is determined that the path is equivalent to the lO pulse in order to bring the rotating body 105 to a standstill. Suppose that However, this value is still limited to a given width of ±20 pulses. It will be understood that this remains within the window. The lO pulse relative to the ideal value is recognized as a deviation by the data collection means 154 which is part of the control unit 155. and is acquired and stored within the control unit 155. While the rotating body makes the next rotation Appropriate amendments will be made. Preparation for accurate positioning of driven element 105 It can be seen that the measurement pulse should be 990. During the next revolution of the rotating body In order to perform positioning, the predetermined 990° It is still necessary to subtract 10 pulses from the expected pulses, resulting in 980 pulses are required for the next rotation of the rotating body. The number of 990 pulses is The basis of the modification for the cycle. Then, 988 pulses are used for the next cycle. This will serve as the standard for

During the measurement following the second rotation of the rotating body, the rotation angle data collection means It is determined that the position of the 992 pulse (actual position) has been reached. The next modification is to switch forward It is necessary to reduce the path by two pulses, and a two-pulse subtraction is performed. In other words , 986 pulses are required for the third rotation of the rotating body.

Instead of the pulses mentioned above, it is also possible to use the time unit during which the rotating body is activated. It is.

The smaller the deviation from the set value after the rotary motor 104 has stopped, the more correction is required. becomes trivial. Refrain from making new modifications just because such modifications have been made. Since new modifications are required due to play and friction in the drive section, Generally not possible. However, such modifications are generally less necessary than the first one. Only a small amount is necessary.

The rotation angle correction means can be applied alternately to the rotating body 105, for example its shaft 112. can.

The zero or starting point for the first measurement is a rigid stop or tappet 1. 17. This stopper 117 is The rotating body 105 can be rotated and can be engaged with a groove appropriately formed in the rotating body 105. Wear. At a later stage of operation, the tappet 117 is not engaged as it is and the rotation of the rotating body is is allowed.

Similar to obtaining the rotation angle, the linear motion deviation is obtained, stored, and used for the next actuation cycle. Of course, it is also possible to make appropriate corrections in the vehicle.

Time intervals and analogs as measured time units instead of ticking into pulses It is also possible to use signals.

A third embodiment of the invention, shown in FIG. This is related to the vertical position of the extension arm 35 on the machine casing l in FIG. The explanation will be based on the motion trajectory S. The diagram in Figure 9 shows the measurement system signals (parameters). the position of the extension arm relative to the distance, length, and time interval).

In the example currently being described, the inductive length measurement system 173 is connected to the curve K1. K2. Generates a signal of current I proportional to the movement length of the arm according to K3 . Both the zero point and the slope of the curve are determined by its length measurement system 173 (AIP Wil d company's IW251/220-05 model, etc.), and the individual measurements of each device The measured values vary within tolerances, and this variation is dependent, among other things, on temperature. “zero point” of the curve ” and inclination are determined as follows. The lowermost position “U” of the extension arm is This is the zero point of the stem.

When determining this position, for example, a tachometer attached to the extension arm 35 may be used. The tall roller 19 is moved to the peg 7 located at the winding position by the stopper 170. It is specified and specified for each person. This position must be set to close tolerances during machine installation. will be cut. and remains unchanged over the entire life of the machine. Uppermost position “0” ” is also determined when installing the machine, and the extension arm 135 is at the lowest position “U” (seat). The correctly defined will be passed through the specified path. The top position “0” remains the same throughout the entire life of the machine. It remains as it is. These two positions (top and bottom) are the output signals to the machine Determine the standard for I (for example, 5 mA at the lowest position “U” and 5 mA at the highest position “o”) 1501A).

Initialization of the length measurement system for the measurement of the path performed by the extension arm 35 is done as follows. Each time the machine is started, the extension arm 35 lifts the lifting device 13. 6, it is lowered to the lowest position.

The lowest position is reached when the position of the extension arm 135 no longer changes. It can be recognized as a thing. At this time, position "U" is read. if position If the position “U” is reasonable and the output signal falls within the predetermined lower tolerance band (Immlm - If it is within Lsaj, the control unit stores the lower value. . Next, the extension arm 35 moves to the upper position "0". Upper position is extension arm 3 It can be recognized that the point has been reached when the position change in step 5 no longer occurs. compromise The validity is examined again and the output value is stored.

The signals of the length measuring system 173, i.e. the upper and lower values, fall within a predetermined tolerance band (Iws When the range is within lm-1w+saj and (Ieslm-L+mayo), the The machine is started (curves Kl and 2). However, if one signal (in the figure If 3) on the curve is outside the tolerance band due to changes in temperature, etc., stop the machine. It is necessary to

Similar to the first example, the shift of the output signal l by the length measurement system 173 This is done instead of time-shifting the element's output signal. ■. and 1. after the decision of Point ■. and ■, it is possible to determine narrower operating tolerance bands.

The extension arm position can be checked for validity after each lowering of the extension arm. Ru. That is, a check is made as to whether the signal value is within the operating tolerance range. Mogami A check of the validity of the side arm position is normally performed after each start of the machine, after a thread breakage, etc. Ru.

The operating tolerance band of the uppermost extension arm position should be selected so that it is narrower. Can be done. That is, the uppermost extension arm position can be reached during the winding operation. This is because, unlike the bottom position, it is completely unchangeable. The lowest position is Depending on the tolerance of the empty bobbin 9, and if there is a gap at startup, the size of that gap Also subject to tolerances.

The continuity of position between two extreme positions can be checked during the entire movement of the bobbin. Ru. Therefore, any position obtained is not within the tolerance band with respect to the last position. Must be.

The length measuring device 173 or the evaluation unit is If the path and absolutely defined position are predetermined, then the slope and position of the curve and can be determined.

In addition to the driving and driven elements described above, other moving parts of the bobbin winder It is also possible to temporarily and locally monitor and correct for mutual movements. Ru. In particular, the movement of the thread in the axial direction by the thread changing device during bobbin replacement is The position of the thread changer during the movement sequence is monitored and corrected. It is also possible to correct the thread, which prevents collisions and guides the thread to the correct position. be able to.

Devices for monitoring and correcting time- or path-dependent cycles are can be integrated into the kit 49 and can therefore be placed in permanent operation. . It is also possible to incorporate it into an independent diagnosis and configuration device 71. This device is It can be connected to the bobbin winder 3 via the interface 73, and this The functional correctness of the moving elements of the bobbin winder is determined in the production or workshop. It can be used to control or modify accuracy if necessary. Which structure Even in manufacturing, a sensor is equipped to obtain the actual value at the bobbin winding machine. . It is also possible to integrate the data memory into the bobbin winder, allowing measurement values and independent Data and correction values sent by the diagnostic and configuration device can be stored.

Fixed or mobile diagnostic and configuration devices are therefore required for parameter evaluation and/or Or it can be used for new settings or calculations.

The method and apparatus of the present invention provide a complex system for moving a plurality of actuator elements relative to each other. It is generally suitable for applications that control integrated systems. Such a cycle is It is known from EP-B-25128 and EP-B-73930.
