Description

The invention relates to a monitoring method for monitoring a deposit position of a winding spool in a winding spool storage device according to the preamble of claim 1 and a monitoring device for carrying out the method according to the preamble of claim 6, as well as a texturing device for false twist texturing a plurality of synthetic threads with a winding spool storage device.

From the prior art, texturing devices for false twist texturing of a variety of synthetic threads are generally known.

It is also known that the synthetic threads textured in the texturing device are deposited into winding spools in winding spool storage units and that these are automatically removed from the winding spool storage unit by means of a winding spool collection vehicle and brought to the corresponding storage locations.

EP1238273B1 discloses a texturing device for false twist texturing a plurality of synthetic threads from supply spools, which provides a plurality of spools with ready-textured threads in a winding device in a winding spool storage for removal from the winding device of the texturing device.

EP0110275B1 discloses a winding spool collection vehicle which is designed to transport and remove winding spools from a winding spool storage unit of a texturing device. The removal of the winding spools from the texturing device can be carried out using appropriate gripping devices.

The problem, however, is that if the winding spool is not stored or positioned correctly in the winding storage, there may be a problem with the mechanical or automated removal of the winding spool from the winding spool storage.

If the reel spool collection vehicle cannot grip the reel spool properly, this can lead to an interruption and, in the worst case, damage to the reel spool storage system caused by the reel spool collection vehicle's removal device.

The object of the invention is therefore to provide a monitoring method for monitoring a deposit position of a winding spool in a winding spool storage, with which it is possible to detect incorrectly positioned and/or deposited winding spools in the winding spool storage.

The object with regard to the method is achieved according to the invention with a monitoring method for monitoring a deposit position of a winding spool in a winding spool storage device with the features according to claim 1.

According to one aspect of the invention, a monitoring method is provided for monitoring a deposit position in a winding spool in a winding spool storage, wherein the winding spool is brought into the winding spool storage in a deposit position for removal and the deposit position is checked by determining a correct position or an incorrect position of the winding spool in the deposit position.

Monitoring the position of the winding spool in the winding spool storage at every position of the texturing device of the winding spool storage offers the advantage that improper and incorrect storage cannot occur, or the incorrectly stored winding spools can be detected in good time before possible damage to the winding spool storage occurs, for example if a winding spool storage vehicle with its removal device wants to remove the incorrectly inserted winding spool from the winding spool storage.

A winding spool is understood here to mean in particular a textured synthetic thread wound on a tube, which has previously been drawn off from a supply spool containing an untextured synthetic thread.

The winding bobbin can be the bare sleeve, a partially wound partial bobbin and/or a correctly wound full bobbin, depending on how well the winding device in the texturing device was working beforehand. Incompletely wound bobbins or not wound bobbins can also occur if, for example, a thread break occurs and/or the synthetic and textured threads are incorrectly traversed in the winding device. This can lead to incompletely wound bobbins being stored in the winding bobbin storage. These still have to be removed from the winding bobbin storage.

However, due to the use of automated winding coil collection vehicles, it is necessary that the position of the winding coil in the winding coil storage is monitored and controlled in a timely manner so that no accidents and/or damage to the winding coil storage occur.

Under a correct position of the winding spool in the winding spool storage, a deposit position the winding spool, which allows easy automatic removal of the winding spool from the winding spool storage with the winding spool collection vehicle.

An incorrect position of the winding spool in the winding spool storage means a deposit position of the winding spool that does not allow the winding spool to be removed easily and automatically from the winding spool storage using the winding spool collection vehicle. For example, if the winding spool is wedged or incorrectly held in the winding spool storage, non-destructive automatic removal using the winding spool collection vehicle is not possible without damaging parts of the winding spool storage or the winding spool itself.

According to one embodiment of the monitoring method, an optical signal is sent from a transmitter through a sleeve on which the winding coil is wound and the signal is received by a receiver.

By sending the optical signal through the sleeve, which is part of the winding spool, the position and inclination of the winding spool can be determined in a simple and inexpensive manner and it can be determined whether the position and inclination of the winding spool are in a correct position and/or in an incorrect position. Certain threshold values can be set here, which can then be used to decide whether the detected position still allows the winding spool to be removed easily and safely from the winding spool storage unit using an automatic winding spool storage vehicle.

According to one embodiment of the monitoring method, the correct position or the incorrect position is determined based on the propagation time of the signal and/or a phase position measurement and/or a laser triangulation of the signal over a predetermined number of placement positions.

Electro-optical distance measurement (also distance measurement) or laser distance measurement is an electronic distance measurement based on a time-of-flight measurement, phase position measurement or laser triangulation of light, mostly laser.

The phase shift of the reflected laser beam or its modulation compared to the emitted beam is distance dependent. This phase shift can be measured and used to determine the distance traveled.

When measuring the time of flight, a short pulse of light is emitted. The pulse time of flight is the time it takes for the light beam to travel from the source to a reflector, usually a retroreflector, and back to the source. By measuring this time of flight, the distance between the source and the object can be determined using the speed of light.

A suitable reflector can be positioned at the corresponding storage position of the sleeve or the respective winding spool storage.

If additional rangefinders are used, reflectors may not be required. Alternatively, a light barrier can be used at predetermined positions so that only one reflector is required per transilluminable length.

According to a further embodiment of the monitoring method, the correct position of the winding spool in the depositing position is determined based on the reception of the signal from the receiver.

Advantageously, a correct position of the winding spool can be determined by the fact that the winding spool is correctly placed in the winding storage because the sleeve does not block the signal and the receiver can therefore receive the signal, which allows it to be concluded that the winding spool is in the correct position, so that a safe, non-destructive and uncomplicated removal of the winding spool from the winding spool storage is possible.

According to a further embodiment of the monitoring method, when the correct position is determined, a release signal is sent to a winding coil collection vehicle and/or to the control of the winding coil storage and/or when an incorrect position is determined, a blocking signal is sent to the winding coil collection vehicle and/or to a control of the winding coil storage.

If an incorrect position of the winding spool in the winding spool storage is detected, for example if the winding spool is not held correctly and properly on the carriers provided for it, which can lead to damage to the winding spool storage of the winding spool and/or the winding spool collection vehicle, a corresponding signal is generated via the monitoring method, which is sent either to the control of the device in which the winding spool of the spool storage is positioned and/or to the corresponding winding spool collection vehicle, so that at least incorrect removal of the incorrectly stored winding spool can be prevented.

Additional signals or commands can also be linked to it. For example, an operator can be informed of the incorrect position and reposition the winding spool in the correct position in good time and then give a release signal to the winding spool collection vehicle so that the winding spool collection process is not interrupted.

The object of the invention is to provide a monitoring device with which the problems described above can be reduced and/or advantageously prevented entirely.

With regard to the monitoring device, the object is achieved according to the invention with a monitoring device having the features according to claim 6.

According to one aspect of the invention, a monitoring device for monitoring a deposit position of a winding spool in a winding spool storage device is provided, which is configured to carry out the monitoring method according to at least one of the preceding embodiments.

The monitoring device comprises a monitoring device comprising a transmitter which emits a signal along a predetermined path and a receiver which receives the signal emitted by the transmitter, the signal being transmitted through the sleeve of the winding spool.

Sending, in particular, through the sleeve of the winding spool allows simple and uncomplicated monitoring of the position of the winding spool in the winding spool storage, without the need for complex additional devices.

This offers the advantage that the monitoring device can also be retrofitted in existing winding coil storage systems.

According to one embodiment of the monitoring device, the transmitter is positioned adjacent to a side support of a rolling track so that the transmitter can transmit the signal through an initial circumference of the sleeve.

The transmitter is advantageously positioned so that it is arranged adjacent to the initial circumference of the sleeve, wherein advantageously several winding spools are arranged one behind the other in a row. This also depends on how many texturing devices are positioned one behind the other, since each texturing device has its own winding spool storage.

Since the arrangement of the winding coil storage units preferably takes place in a linear path, it is possible that a plurality of winding coil storage units arranged one behind the other and winding coils arranged thereon can be controlled by means of a single transmitter. If the signal can be sent through the sleeves of the winding coil storage units and can be received by an associated receiver, it can be concluded that the winding coil is correctly positioned in the winding coil storage unit.

According to a further embodiment of the monitoring device, the receiver is positioned in the signal direction in a receiving position on the sleeve which is opposite to the initial circumference of the sleeve and opposite to the end circumference of the sleeve.

This provides the uncomplicated positioning of transmitter and receiver presented above, with the transmitter located at the initial circumference and the receiver at the end circumference of the sleeve.

According to a further embodiment of the monitoring device, the transmitter is positioned on the side support such that the signal is guided in the signal direction in an annular signal zone, wherein the signal zone is defined by the inner circumference of the sleeve and a predetermined signal diameter extending from the center of the sleeve.

This offers the advantage that, depending on the permissible threshold value of the position of the core in the winding storage, a more precise position detection is possible by simply changing the position of the transmitter and the receiver relative to the core diameter, so that even small deviations in the position of the winding coil in the winding coil storage can be detected.

According to a further embodiment of the monitoring device, the monitoring device is configured to transmit, receive and/or measure the propagation time of the signal.

In particular, the measurement of the signal's transit time allows an accurate determination of the position of the winding coil or coils that are not correctly stored in the winding coil storage, in particular when a plurality of winding coils are arranged one behind the other in series in the winding coil storage.

According to another embodiment of the monitoring device, the monitoring device is designed for phase position measurement and/or for laser triangulation of light, in particular lasers.

This also allows the position to be monitored if, for example, the light or the optical signal is not completely blocked by the incorrectly stored sleeve and the receiver still receives a signal, so that even if there is a phase shift of the optical signal due to a deflection on the sleeve, an incorrectly placed and stored winding spool can be detected in the winding spool storage.

A further object of the invention is to provide a texturing device for false twist texturing of a plurality of synthetic threads, with which an uncomplicated and safe removal of winding spools from the associated winding spool storage is possible without causing damage to the winding spool storage and/or to the winding spools when an automated winding spool collection vehicle is used.

The object with regard to the texturing device is achieved with a texturing device having the features according to claim 11.

According to one aspect of the invention, a texturing device for false twist texturing of a plurality of synthetic threads is provided with a corresponding plurality of processing stations, wherein the threads are conveyed and stretched by means of a first, second and/or third delivery drive and textured by means of a texturing device and wound up into winding spools in a winding device, wherein the wound up winding spool can be deposited in a winding spool store, wherein the deposit position of the winding spool in the winding spool store is monitored by a monitoring method according to at least one of the preceding embodiments and/or by a monitoring device according to at least one of the preceding embodiments.

The monitoring device according to the invention and the monitoring method according to the invention as well as the associated texturing device are explained in more detail below using some embodiments of the monitoring device, the monitoring method and the associated texturing device with reference to the attached figures.

For better orientation and allocation of the individual features, reference coordinate systems with X, Y, Z directions are given in selected figures, where 1 displays the reference XYZ coordinate system.

In the reference coordinate system, X indicates the longitudinal direction of the texturing device 100, Y indicates the width direction of a texturing device 100, and Z indicates the height direction of the texturing device 100.

In detail views, this is always in 1 The reference coordinate system shown is provided for better orientation and assignment of the features to the texturing device 100.

1 schematically shows the texturing device 100 for texturing a synthetic yarn FS, which is provided by means of supply bobbins 7 stored in a bobbin creel 2.

For this purpose, the synthetic thread FS or the plurality of synthetic threads FS from the respective supply spools 7 is fed via deflection rollers 9 first over and through a heating device 120 for heating the synthetic thread FS, after subsequently brought to a cooling device 130 for cooling or tempering the synthetic thread FS to a predetermined temperature so that false twist texturing can be carried out via a false twist texturing device 150.

The texturing carried out by the false twist texturing 150 is then fixed in the synthetic thread FS with a heating device 140. The textured thread TS is then wound in a winding device 1 to form winding spools 4, which are then made available for transport in a winding spool storage device 30.

For transporting, conveying and stretching the synthetic thread FS, which is also part of the texturing, the synthetic thread FS is drawn and transported by the creel 2, which is provided in supply spools 7, via a first delivery system 11, a second delivery system 12 and fed to the winding device 1 via a third delivery system 13.

The winding device 1 has an associated traversing device 20, by means of which the textured thread is wound onto the respective winding spool 4.

By means of a winding spool swivel arm 40, the respective spool 4 can be fed to the winding spool storage 31.

The respective winding spool storage device 30 has a rolling track 31 that functions like a heavy-duty slide. The winding spools 4 are held and guided accordingly via the rolling track 31 over the projecting sleeve sections of the sleeve 21 on which the textured thread T has been wound.

The unwinding track 31 has a stop 32 at its unwinding end. The stop 32 can also be a recess which is designed to be circular so that at least a portion of the sleeve circumference of the sleeve 21 can be held there so that the winding spool 4 can be held in a storage position A, as in 3 shown, is held in the rolling track 31.

As further from 3 As can be seen, the unwinding track 31 has side supports 33 which hold the sleeve 21 of the winding spool 4 on both sides.

A maintenance aisle 200 is provided for operators to maintain the texturing device 31, and a vehicle aisle 210 is provided for collecting and removing the winding spools 4 from the winding spool storage 30, in which, for example, self-propelled vehicles, which can be rail-guided and/or freely movable via corresponding position controls, such as a winding spool collection vehicle 70, can drive.

In 2 the texturing device 100 is made of 1 with a winding spool collecting vehicle 70 when removing winding spools 4. The winding spool collecting vehicle 70 can have a paternoster rack 75 on which a predetermined number of storage shells 74 are provided, the number of which essentially corresponds to the number of winding spool stores 30 in the texturing device 100.

Depending on the position and number of winding devices 1 in the respective texturing device, a corresponding number of bearing shells 74 can be provided in the longitudinal direction X, in which the respective winding spool 4 can be placed in the associated bearing shell by means of a feed lifting arm 77 of the winding spool collecting vehicle 70.

In an embodiment of the winding spool collecting vehicle 70, not shown, only levels can be provided, wherein the necessary lifting of a bearing shell 74 takes place with the pivoting movement of the feed lifting arm 77 for the respective level.

The winding coil collection vehicle 70 has an associated drive system 76. The drive system 76 can be a rail guide that is ceiling- or floor-guided. The winding coil collection vehicle 70 can also be designed as an AGV vehicle that has appropriate vehicle tires and can determine its position and location via appropriate sensors.

Furthermore, in the 1 and 2 the position of the monitoring device 50 is indicated, with which a correct deposit position of the respective winding spool in the winding spool storage 30 can be determined, so that the winding spool collecting vehicle 70 can automatically and easily and without damage remove the respective winding spool 4 from the winding spool storage 30 by means of the feed lifting arm 77 and deposit it in the associated storage shell 74.

When the winding bobbin collection vehicle 70 has removed the winding bobbins 4 from the winding bobbin storage 30, the winding bobbin collection vehicle 70 travels, for example, to a storage position in the hall in which the texturing device is arranged, so that further winding bobbins 4 can be processed from the synthetic threads FS to form textured threads TS.

Typically, a plurality of texturing devices 100 are provided so that a corresponding number of winding spools 4 are produced and stored throughout the day.

However, it may happen that the winding spools 4 are incorrectly positioned in the winding spool storage 30 by the feed lifting arm 77 and are not arranged in the correct deposit position A in the winding spool storage 30.

An incorrectly placed winding spool 4 is, for example, 5 shown.

To better understand the idea, reference is first made to 3 , in which a correctly deposited winding spool 4 is shown, and the associated flow chart or runtime diagram are discussed.

In 3 is a schematic longitudinal view of a spool storage device 30 in which a predetermined number of winding spools 4 are held in the unwinding track 31, which have corresponding side supports 33 with associated stops 32, which hold the winding spool in the depositing position A so that the winding spool collecting vehicle 70 can remove it by means of its feed lifting arms 77.

The monitoring device 50 is arranged on opposite end sides of the winding spool and has a transmitter 51 and a receiver 52, so that a signal S can be sent from the transmitter 51 to the receiver 52 through the sleeve 21 in order to thereby determine the correct deposit position A.

Preferably, the signal S is sent from a diameter start d _A , which also belongs to a circumference start U _{A ,} to a diameter end d _E or circumference end U _E of the respective sleeve 21 of the winding spool 4.

The signal S passes through a plurality of winding spool positions P1, P2 to PN, starting from the position P0 of the transmitter, where PN indicates the end position of the receiver 52. However, a plurality of winding spools 4 can be arranged in the winding spool storage 30 between P0 and PN, depending on how the texturing device 100 and the associated winding device 1 are designed.

In 4 A runtime diagram is shown schematically, which shows the runtime of the diagram over the individual positions P0 to PN in the runtime direction m over the time t. For better understanding, the runtime diagram is shown in abbreviated form.

If the deposit position A is correct, it can already be determined from the runtime diagram that the winding spool is in the correct deposit position A at each position P1 to PN, since the signal S is neither deflected nor reflected and has reached and been received by the receiver 52 without blockage.

When all winding spools 4 are in the correct storage position A in the associated winding spool storage 30, the monitoring device 50 then sends a release signal to the control of the texturing device 100 or to the control of the winding spool collection vehicle 70 that the winding spools 4 are in the correct storage position and can be removed from the winding spool storage 30.

5 shows an example in which the winding spools 4 are arranged in a correct storage position A and in an incorrect position F.

The incorrect position F is indicated by the reference symbol F on the corresponding winding spool 4, which is inclined by an angle with respect to the signal S which is essentially horizontal in the X direction.

The signal S, which has been sent by the transmitter 51 in the position P0 to the winding spool P2 in the incorrect position F, is reflected, for example, by the sleeve 21 or by the support section of the unwinding track 31 back to the transmitter 51 and is detected as an incorrect signal SR or as a reflected signal SR by the monitoring device 50, which can also have a receiver 52.

This can cause the 6 given time-of-flight diagram, wherein the signal S is not received by the receiver 52 at the position PN, but by the receiver 52 at the position P0.

This makes it possible to determine that the winding spool 4 is not correctly positioned at position P2 and the removal by the winding spool collecting vehicle 70 can be interrupted in time.

As further from 3 and 5 As can be seen, the receiver 52 is arranged in the signal direction S in a receiving position at the sleeve end of the circumferential end section of the winding spool 4, but not necessarily on the side support 33 of the spool store 30.

As further from 6 can be seen from the running time and the running time diagram. It can be assumed that a winding spool 4 is positioned in an incorrect position F when the signal arrives back at the transmitter 51 as a reflected signal SR. The incorrect position F can also be detected if, after a time t, the reflected signal SR is also detected at the original position P0 by the transmitter 51 positioned there.

In the case of such a message, the control of the monitoring device or the control of the texturing device 100 is set up in such a way that at least one warning signal is sent to the vehicle collection device 70 and at the same time a corresponding message is sent to an operator, so that the operator can correct the incorrect storage position F if this is possible without any effort, or can also take appropriate measures to correct the errors that occur.

7 shows a front view of a correctly deposited winding spool in the winding storage 60.

Since the side supports 33 of the unwinding track 31 are arranged essentially parallel to one another, the position of the center point M of the winding spool 4 at the center point start MA is equal to the position of the center point end ME at the end point of the sleeve 21, which also applies to the diameter start d _A and the diameter end d _E of the sleeve 21, or the circumference start UA or the circumference end UE of the winding spool 4.

Furthermore, in 7 the diameter d _S of a signal zone SZ is specified, which is preferably annular and extends from the inner circumference of the sleeve 21 at a predetermined distance from the edge to the center M of the sleeve 21.

Preferably, the signal S is emitted at the edge in the signal zone SZ, so that even small changes in the inclination of the coil 4 in the deposit position can be detected, since this makes it easier for the sleeve circumference to reflect or block a signal S, which can be determined by a corresponding evaluation at the receiver 52, for example by a phase shift.

Preferably, the signal S is a laser signal, whereby errors can be detected by means of appropriate laser triangulations and/or a phase position measurement at the receiver 52 or at the transmitter 52. It can also be determined at which position P1 to PN there is an incorrect placement in the incorrect placement position F of the winding spool 4, so that the operator can also find the position in a targeted manner and correct it accordingly.

In 8 a winding spool 4 is shown which is arranged in the wrong deposit position F in the winding spool storage 30. Here it can be immediately seen that the circumferences of the circumference start UA and the circumference end UE do not overlap but are offset from each other, which also applies to the diameter start d _A and the diameter start dE, as well as to the corresponding center points MA and ME at the beginning and end of the winding spool 4 or the sleeve 21.

This also results in a reflection on the inner circumference of the sleeve 21, in particular in the annular signal zone SZ, so that incorrect deposit positions F can be detected by the inclination of the sleeve 21.

Accordingly, the signal zone SZ can also be selected with a smaller range so that even small deviations can be detected. In 7 or 8 For better recognition, the area of the signal zone SZ is exaggerated.

9 shows a schematic block diagram of essential method steps of the monitoring method according to the invention.

In the texturing device 100, essential process steps for false twist texturing of a synthetic thread FS for winding the synthetic thread FS, which has been textured into a textured thread TS, have already been carried out. In the winding device 1 of the texturing device 100, the textured thread TS was wound into a winding spool 4, which is brought into the winding spool storage of the texturing device 100 in the first process step S1.

In subsequent steps, the storage position is checked in step S2, whereby the correct position K in the storage position A or an incorrect position IK in the incorrect position F is determined.

For this purpose, in step S4, a signal S is sent through the sleeve 21 of the winding spool 4 by a transmitter 51 of the monitoring device 50 and the signal S is received by a receiver 52 in a subsequent step S6, wherein the receiver 52 is preferably arranged at an opposite position to the transmitter 51. The transmitter 51 and receiver 52 can also have both functions of a transmitter and a receiver, so that in particular the reflected signal SR can be detected.

In a step S4, the transit time of the signal S is determined so that the corresponding position P0 to PN of the signal S can be used and recorded at a specific time t. so that, for example, the position P01 to P0n at which the signal S is currently located can be recorded. Furthermore, the signal S can be used for a phase position measurement or a laser triangulation if the signal S is aligned accordingly.

In a step S5 it is determined whether the correct position of the winding spool 4 is present in the depositing position, for example by comparing the running time t with stored data.

If the signal S is in particular a laser signal, a corresponding phase position measurement or laser triangulation can be carried out so that the position P1 to PN and also the position can be controlled and tracked accordingly to determine whether the winding spool 4 is positioned in the correct deposit position A.

If the winding spool 4 has been placed in the incorrect position F with a predetermined angle of inclination, the signal S is deflected and/or reflected in a modified manner, whereby a corresponding extension of the running time can be detected and/or phase shifting and/or laser triangulation can be carried out, via which it can then be determined that the winding spool 4 is arranged in an incorrect position F.

In a step S6, either a release signal and/or a blocking signal is then sent, for example, to the winding spool collection vehicle 70, wherein the release signal enables the winding spool collection vehicle 70 to collect the winding spools 4 collected in the winding spool storage 30.

In the case of a blocking signal, an operator is preferably notified at the same time and/or the approach of the winding spool collection vehicle 70 to the corresponding position with the incorrect deposit position is prevented at the same time, so that incorrect collection and, in the worst case, damage to the winding spool collection vehicle 70 or to the texturing device 100 due to incorrect or incorrect removal of the incorrectly deposited winding spool 4 can be prevented.
