Definitions
- the invention relates to a method and a device for automatically monitoring a gripper carrier for a rapier weaving machine and a gripper carrier.
- a weft thread is transported by at least one gripper and a gripper carrier through a shed.
- a gripper carrier may be a gripper bar, a gripper belt or a guide member which is arranged in extension of the gripper bar or the rapier band.
- a guide part is for example from the EP 576 854 B1 and the EP 972 099 B1 known. This leadership part is also called "Greifersohte".
- a channel is provided in a deflection guide, which guides the rapier band around a drive wheel, which is assigned to the region of the rapier band which is not subject to wear by the other guide elements, in particular the guide element located in the region of a shed.
- the gripper belt thus has a central region which is not exposed to wear. If the ones next to it Worn lateral areas, so the unused central area protrudes into the recess of the deflection guide. This condition is detected either by a pressure sensor or by an optical sensor.
- a two-part photoelectric sensor is provided whose beam path is interrupted by the unrated gripper band. If the wear is so great that the beam path between the two parts of the photoelectric sensor is free, this is a sign of wear, which requires an exchange of the rapier band.
- the invention has for its object to provide a method, a device and a gripper carrier, which allow automatic monitoring without causing significant changes in the gripper carrier in terms of its properties.
- This object is achieved in a method in that at least one identification element is embedded in the gripper carrier, which has a substantially smaller length compared to the length of the gripper carrier, and that the identification element by means disposed in the movement path of the gripper carrier detection device during the passage of the gripper carrier is monitored without contact.
- the relatively small identification element does not appreciably affect or alter the structure and properties of the gripper carrier. Its presence can be detected as it passes the detection device, even if the passage is at a relatively high speed.
- the at least one identification element is disposed within the gripper carrier exposed to a wear point and that, if due to wear the gripper carrier, the identification element is exposed, a wear of the identification element takes place, whereby its identification function is changed.
- the gripper carrier at least one identification element is embedded, which has a much smaller compared to the length of the gripper carrier length, and that in the movement path of the gripper carrier a non-contact, the passage of the 1 Dentgebers institutes detecting detection device is arranged.
- the at least one identification element is arranged within the gripper carrier at a point exposed to wear, and that the identification element is changeable due to wear with respect to its identification function.
- An inventive gripper carrier is characterized in that in the gripper carrier at least one non-contact due to its electrical properties of a detection device recognizable identification element is embedded.
- the identification element may have the shape of a coil.
- the identification element can be printed on a layer of a gripper carrier assembled from several layers. It can also be an element which is arranged on a layer or molded in a gripper carrier. In an embodiment of the invention, it is provided that the identification element is an RFID transponder. This is then assigned as a detection device, a reading unit, in particular a transmitting-receiving unit.
- a part of a rapier which includes a gripper carrier 1, which consists of a gripper belt 2.
- the gripper belt 2 is driven by means of a drive wheel 3 to reciprocating movement. It is held by means of guide blocks 4 and 5 on the circumference of the drive wheel 3.
- the guide blocks 4 and 5 are attached to a frame, not shown, of the rapier.
- the rapier band 2 is guided by means of a stationary guide element 6, which is arranged laterally next to a shed formed by the rapier loom and attached to the frame of the weaving machine, not shown. Within the shed the rapier band 2 is guided by means of known guide elements 8, which are arranged on a sley 7 and move with the sley 7.
- Attached to the rapier band 2 is a gripper 9 which is indicated only schematically, which grasps a weft thread and brings it into the shed.
- the guide elements 8 are located substantially in extension of the guide element 6 when a weft thread is introduced.
- an identification element 10 is embedded, which has a relatively small length compared to the total length of the rapier band 2. It is located in the region of the front end of the rapier band 2, ie in the area below the gripper 9. As in Fig. 2 and 4 is shown, serves as an identification element 10 in the embodiment, a short-circuited coil 11 which is embedded in the gripper belt 2.
- the identification element 10 present in the gripper carrier 1 is detected by means of a detection device 12, which is arranged in the region of the movement path of the gripper carrier 1 and is attached, for example, to the frame of the rapier weaving machine.
- the trajectory of the gripper carrier 1 is determined by the position of the guide blocks 4, 5, by the position of the stationary guide element 6 and by the position of the movable with the sley 7 guide elements 8.
- the detection device 12 detects the contactless passing of the identification element 10, which passes along with the gripper carrier 1 to the detection device 12 over.
- the detection device 12 is mounted on the frame of the rapier loom, in the embodiment in the region of the stationary guide member 6.
- the guide member 6 is provided with a recess into which the sensor of the detection device 12 inserted and then surrounded with non-conductive and non-magnetizable material so that the recess is filled.
- the arranged in the path of movement of the gripper carrier detection device 12, which operates in the illustrated example with induction, is thus insensitive to contamination by dust or the like. and / or against mechanical damage.
- the detection device 12 in the embodiment includes a resonant circuit having a capacitor and a coil that is resonated so that a resonance signal is generated. This resonance signal is only slightly damped. However, when the short-circuited coil serving as the identification element 10 passes the resonant circuit, this resonant circuit is loaded (similar to a transformer with a short-circuited secondary winding), so that a signal with a lower amplitude is generated.
- the gripper carrier 1 passing by the short-circuited coil 11 on the detection device 12 thus causes a change in the signal of the detection device 12.
- the function is based on induction.
- the identification element 10 has relatively small dimensions, for example of the order of 2 mm to 5 mm, in the longitudinal direction and in the transverse direction of the gripper carrier 1, which usually has a width of 15 mm. less than the width of the gripper carrier. 1
- the identification element 10, ie, in the exemplary embodiment, the short-circuited coil 11, is embedded in the area of a position of the gripper carrier 1, which is exposed to wear. If the gripper carrier 1 has worn and worn so far that the courses of the short-circuited coil 11 are exposed, so these are also worn, ie cut or broken. This damages the previously shorted coil so that it is no longer short-circuited. The damaged and no longer short-circuited coil 11, which passes by the detection device 12, no longer changes the signal of the detection device 12. In this way, it is detected that the wear of the gripper carrier 1 has progressed so far that it has reached the serving as an identification element 10 short-circuited coil 11, which corresponds to a predetermined degree of wear.
- This degree of wear can be determined by the position of the identification element 10 within the gripper carrier 1 so that it corresponds to a critical wear, the one Replacement of the gripper carrier 1 requires. It should be noted that the damage of the identification element 10, ie the damage of the previously shorted coil 11, is detected without contact, since the resonant circuit of the detection device 12 is no longer attenuated and generates a constant signal.
- short-circuited coil 11 is formed as a so-called "flexprint", ie as a flexible printed circuit 19, in which a small coil formed by conductor 18 11 is integrated.
- the short-circuited coil 11 is printed as a substantially helically extending conductor 18 on a flexible material. The inner end and the outer end of the spiral are connected to each other on the back of the flexible member, so that the coil 11 is closed.
- Such an identification element 10 in the manner of a small element, for example in the form of a label or a sticker or the like. with a printed circuit has the advantage that it can be mounted at a precisely predetermined location corresponding to the critical wear, in which the gripper carrier 1, in this case the gripper belt 2, must be replaced.
- the coil 11 applied as a printed circuit 19 on a flexible material, for example, is arranged between the layers of the rapier band 2 when producing a laminated rapier band.
- the coil 11 is attached to the location, which, as the in Fig. 3 is shown, located at a predetermined distance from the bottom and the front end of the rapier band 2.
- the bobbin 11 is secured between the layers of the rapier band 2 before the layers are joined together in an oven under pressure. In this case, the coil 11 must endure relatively high temperatures and relatively high pressures, ie the insulation between the conductors 18 of the coil 11 must withstand relatively high temperatures and relatively high pressures.
- the coil 11 need not be arranged parallel to the top or bottom of the rapier band 2.
- the formed as a flexprint coil 11 can be bent in a suitable manner.
- the already finished rapier band 2 is provided with an outgoing from its upper side bore 13 into which the coil 11 is inserted.
- the bore 13 is then filled with a sealant, in particular poured, so that it is arranged at a precisely defined position in the gripper belt 2.
- the gripper belt 2 is provided with a guide part 14 extending in its extension, on which a gripper 9 is mounted.
- This guide part 14, which is for example a plastic injection-molded part, contains the identification element 10, which may also consist of a short-circuited coil 11 here.
- This coil 11 is embedded in the guide member 14 during injection molding.
- Serving as the identification element 10 coil 11 is housed in a relatively well-defined location in the guide member 14 and is located at a predetermined distance from the bottom of the guide member and at a predetermined distance from the front end.
- the embodiment according to Fig. 6 carries the guide member 14 alone the gripper. 9
- an identification element 10 which is embedded in the rapier band 2, as an RFID transponder 15 [(radio frequency identification element)], for example an RFID tag or RFID tag or label.
- RFID transponder 15 can cooperate with a detection device 12, which consists of a transceiver unit that reads data stored on the RFID by radio waves.
- An RFID transponder 15 may include, for example, a chip, a coil, and conductors connecting the coil to the chip. If the rapier band 2 is worn so far that the RFID transponder 15 embedded in its interior is damaged, then no signal is sent back to the detection device 12. The damage of the RFID transponder 15 can take place on the chip and / or the coil and / or the conductors. The thus determined degree of wear of the rapier band 2 can be used as an opportunity to replace the rapier band 2.
- two identification elements 10 are provided on the gripper carrier 1, namely on the gripper belt 2 and also on the gripper belt 2 extending guide member 14.
- the identification elements 10 are exploited to determine the one part wear of the gripper belt 2 and on the other hand, the wear of the guide member 14.
- the identification element 10 of the rapier band 2 from a coil 11 while the identification element 10 in the guide member 14 is a transponder, such as an RFID transponder.
- the gripper 9 extends in this embodiment via the guide member 14 and over the beginning of the rapier band. 2
- the invention assumes that when the gripper carrier 1, ie a gripper belt 2 and / or a guide member 14, wear and thus become thinner, the present in the gripper carrier 1 identification element 10 from a certain wear of the gripper carrier 1 with the guide. 6 and / or the guide elements 8 in contact. From this state, the identification element 10 is also exposed to wear, so that it is damaged and loses its identification function. This functional failure is detected by the detection device 12. The damage can in a short-circuited coil by the rubbing through a conductor of the coil 11 and caused by the rubbing away of a part in an RFID transponder 15.
- the detection device 12 cooperates with a control unit 16, for example, to shut down the rapier when the short-circuited coil 11 and / or the RFID transponder 15 are damaged.
- the control unit 16 may then generate, for example, a warning signal, in particular turn on a light, so that the operator is made aware that the gripper carrier 1, ie the rapier 2 and / or the guide member 14, are worn so far that an exchange required is.
- the control unit 16 is also connected in the embodiment with a display 17 on which the wear is displayed.
- Both in a gripper belt 2 and in a guide part 14 two identification elements 10 and 20 are embedded. Both identification elements 10 and 20 may be a coil 11, which are arranged at different distances to the bottom and the front end of the rapier band 2 and / or the guide member 14. Both for the rapier band 2 and for the guide part 14, two identical identification elements 10 and 20 in the form of a coil 11 or in the form of an RFID transponder 15 may be provided. It is also possible that in each case one identification element 10 or 20 is designed as a coil 11 and the other identification element 20 as an RFID transponder. It is also possible to provide for the rapier 2 two identical identification elements and for the guide member 14 also two similar, but the other type corresponding identification elements.
- the control unit 16 can evaluate that so that the gripper belt 2 or the guide member 14, although worn, but not yet completely worn.
- the control unit 16 may then generate a signal indicating that the rapier band 2 and / or the guide member 14 needs to be replaced soon. If then also an identification element 10 is damaged, which is farther away from the bottom, the signal is generated that a replacement must be made. In this case, for example, the rapier may be stopped by this signal.
- the rapier band 2 and / or the guide part 14 contain more than two identification elements 10, 20.
- the gripper belt 2 contains two identification elements 10, for example, two RFID transponders 15.
- An identification element 10 is closer to the top of the rapier band 2 and indicates when the top of the rapier band 2 has reached a certain wear.
- the other identification element 10 is arranged closer to the underside in the rapier band 2 and indicates when the underside of the rapier band 2 has reached a certain state of wear.
- the gripper belt 2 usually wears to a greater extent at the top. If guide elements 8 are provided, a rapier band 2 may eventually wear on the underside.
- identification elements 10 closer to the top and closer to the bottom of the rapier band 2 can regardless of their type and regardless of the presence of guide elements 8 in the shed and regardless of whether the rapier band 2 faster above or faster down worn on any rapier is, a replacement requiring wear of the rapier band 2 are determined.
- the identification element 10 according to the invention at one point of the rapier band 2 and / or the Guide member 14 attached which is subject to the greatest wear.
- the identification elements 10, which are associated with the top side and the bottom side can each work together with their own detection devices 12. However, it is also possible to provide only one detection device 12 which, as long as none of the identification elements 10 is damaged, detect two successively generated signals. If only one signal is then generated due to the damage of an identification element 10, this is a signal that the gripper carrier in question is worn out.
- the identification element 10 of Fig. 11 has except a coil 11 nor a capacitor 21 which is connected to the two ends of the coil 11.
- This identification element 10 can be used as a resonant circuit or tuned resonant circuit. It makes it possible to cause a larger change in the signal of the detection device 12 than a short-circuited coil 11 alone at a certain moving speed of the identification element 10. Damage caused by wear of such an identification element 10 can be done by damaging the conductor or the capacitor 21.
- the identification element 10 is replaced not only by a capacitor 21, but by an electrical resistance, by a diode, by a transistor or other electrical elements or by another electrical circuit. Such an identification element 10 is then designed so that at a certain speed of movement of this identification element 10 a signal corresponding to this movement speed is generated with the aid of the detection device 12.
- the detection device 12 is not arranged in the region of the guide element 6, but in the Area of one of the guide elements 8. If the detection device 12 is arranged in the region of a guide element 8 that is in the vicinity of the transfer position of a Geberreifer to a gripper rapier, with the detection device 12, the time of the weft transfer is detected.
- a plurality of identification elements 10 or 20 are provided, it is also possible to provide a plurality of detection devices, each working together with one of the identification elements 10 or 20.
- the detection devices can then be arranged at different locations, for example a detection device 12 in the region of the guide element 6 and another detection device 12 in the region of a guide element 8.
- the advantage of a gripper carrier 1 with an identification element 10, 20 according to the invention is the low price of the identification element 10, 20 and its low weight.
- the identification element 10, 20 can be adapted in a simple manner to the shape of the gripper carrier 1 and integrated into each rapier band 2 or each guide member 14.
- there is a non-contact detection of wear whereby the detection device has virtually no influence on the gripper carrier 1.
- the distance between The detection device 12 and the identification element 10, 20 is not critical and can be chosen to be relatively large, ie on the order of several millimeters.
- Such a detection device 12 and such identification elements 10, 20 are insensitive to dust, whereby they are very suitable for rapier looms.
- each gripper carrier By means of the invention it can be determined exactly for each gripper carrier when its wear is so strong that it has to be replaced. This makes it possible to use the gripper carrier 1 as long as possible. This is advantageous over a method in which each gripper carrier is basically replaced after a certain number of operating hours.
- each gripper carrier is basically replaced after a certain number of operating hours.
- premature wear of a gripper carrier 1 is detected in good time, so that a breakage of the gripper carrier 1 can be avoided.
- a longer lasting gripper carrier 1 is used as long as possible.
- the invention further offers the advantage that other functions can be realized. For example, not only the wear of a gripper carrier 1 can be determined. It is also possible to detect the position of the gripper carrier 1 with respect to the angular position of the drive wheel 3. In this case, for example by means of the control unit 16 of the rapier loom, the angular position of the drive wheel 3 are stored, in which the identification element of the detection device 12 is opposite. This can be detected during weaving, whether a rapier band is torn and / or whether a rapier band 2 has been correctly attached by checking whether the signal of the detection device 12 is generated at a desired angular position of the drive wheel 3.
- the signal of this RFID transponder 15 can also be used to make certain settings of the rapier loom automatically.
- the RFID transponder 15 of the guide member 14 and / or the rapier band 2 may contain data that allow automatic adjustment of the speed of the rapier.
- the data of this RFID transponder 15 can be read, for example, when the rapier is operated in creeper, since this reading is not required for each weft insertion.
- the data for the rapier band 2 and / or the guide part 14 can also be used to detect which rapier band 2 and / or which guide part 14 a worn rapier band 2 and / or a worn guide part 14 must be replaced. It is also possible to check whether a new rapier band 2 and / or a new guide part 14 with the worn rapier band 2 and / or worn guide member 14 is identical.
- gripper looms in which two grippers 9 are provided with gripper carriers 1, namely a Gebergreifer 9, which brings a weft thread from one side to the middle of the shed, and a gripper rapier, which takes over the weft thread in the middle of the shed and the opposite Side of the shed brings, on both sides of the loom facilities according to the representation Fig. 1 intended. If only one gripper 9 is used with a gripper carrier 1 to completely transport the weft thread through the shed, of course, only one device is accordingly Fig. 1 intended.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren, eine Vorrichtung und einen Greiferträger zu schaffen, die eine automatische Überwachung ermöglichen, ohne wesentliche Veränderungen des Greiferträgers bezüglich seiner Eigenschaften zu bewirken.The invention has for its object to provide a method, a device and a gripper carrier, which allow automatic monitoring without causing significant changes in the gripper carrier in terms of its properties.

In
In dem Greiferträger 1, d.h. bei dem Ausführungsbeispiel nach
Die Erfassungsvorrichtung 12 erkennt berührungslos das Vorbeilaufen des Identifizierungselementes 10, das zusammen mit dem Greiferträger 1 an der Erfassungsvorrichtung 12 vorbei läuft. Bei dem Ausführungsbeispiel ist die Erfassungsvorrichtung 12 an dem Rahmen der Greiferwebmaschine angebracht, bei dem Ausführungsbeispiel in dem Bereich des stationären Führungselementes 6. Das Führungselement 6 ist mit einer Aussparung versehen, in welche der Sensor der Erfassungsvorrichtung 12 eingesetzt und anschließend mit nichtleitendem und nichtmagnetisierbarem Material umgeben wird, so dass die Aussparung ausgefüllt ist. Die in der Bewegungsbahn des Greiferträgers angeordnete Erfassungsvorrichtung 12, die bei dem dargestellten Beispiel mit Induktion arbeitet, ist somit unempfindlich gegenüber Verschmutzen durch Staub o.dgl. und/oder gegen mechanisches Beschädigen.The
Die Erfassungsvorrichtung 12 enthält bei dem Ausführungsbeispiel einen Schwingkreis mit einem Kondensator und einer Spule, der zur Resonanz erregt wird, so dass ein Resonanzsignal generiert wird. Dieses Resonanzsignal ist nur wenig gedämpft. Wenn jedoch die als Identifizierungselement 10 dienende, kurzgeschlossene Spule an dem Schwingkreis vorbeiläuft, so wird dieser Schwingkreis belastet (ähnlich einem Transformator mit kurzgeschlossener Sekundärwicklung), so dass ein Signal mit niedrigerer Amplitude generiert wird. Der mit der kurzgeschlossenen Spule 11 an der Erfassungsvorrichtung 12 vorbeilaufende Greiferträger 1 veranlasst somit eine Änderung des Signals der Erfassungsvorrichtung 12. Die Funktion basiert auf Induktion. Das Identifizierungselement 10 hat in Längsrichtung und in Querrichtung des Greiferträgers 1, der üblicherweise eine Breite von 15 mm aufweist, relativ kleine Abmessungen, beispielsweise in der Größenordnung von 2 mm bis 5 mm, d.h. weniger als die der Breite des Greiferträgers 1.The
Das Identfizierungselement 10, d.h. bei dem Ausführungsbeispiel die kurzgeschlossene Spule 11, ist im Bereich einer Stelle des Greiferträgers 1 in diesen eingebettet, die einem Verschleiß ausgesetzt ist. Wenn der Greiferträger 1 so weit abgenutzt und verschlissen worden ist, dass die Gänge der kurzgeschlossenen Spule 11 frei liegen, so werden diese ebenfalls verschlissen, d.h. durchgeschnitten oder durchbrochen. Damit wird die vorher kurzgeschlossene Spule so beschädigt, dass sie nicht mehr kurzgeschlossen ist. Die an der Erfassungsvorrichtung 12 vorbeilaufende beschädigte und nicht mehr kurzgeschlossene Spule 11 verändert das Signal der Erfassungsvorrichtung 12 nicht mehr. Auf diese Weise wird erfasst, dass der Verschleiß des Greiferträgers 1 so weit fortgeschritten ist, dass er die als Identifizierungselement 10 dienende kurzgeschlossene Spule 11 erreicht hat, was einem vorbestimmten Verschleißgrad entspricht. Dieser Verschleißgrad kann durch die Position des Identifizierungselementes 10 innerhalb des Greiferträgers 1 so bestimmt werden, dass er einem kritischen Verschleiß entspricht, der einen Austausch des Greiferträgers 1 erfordert. Es ist zu erwähnen, dass die Beschädigung des Identifizierungselementes 10, d.h. die Beschädigung der vorher kurzgeschlossenen Spule 11, berührungslos erfasst wird, da der Schwingkreis der Erfassungsvorrichtung 12 nicht mehr gedämpft wird und ein gleichbleibendes Signal erzeugt.The

Die als gedruckte Schaltung 19 auf einem flexiblen Material aufgebrachte Spule 11 wird beispielsweise beim Herstellen eines laminierten Greiferbandes zwischen den Lagen des Greiferbandes 2 angeordnet. Die Spule 11 wird an der Stelle angebracht, die sich, wie das in
Die Spule 11 muss nicht parallel zur Oberseite oder Unterseite des Greiferbandes 2 angeordnet werden. Beispielsweise kann die als Flexprint ausgebildete Spule 11 in geeigneter Weise gebogen werden. Bei dem Ausführungsbeispiel nach

Die Erfindung geht davon aus, dass dann, wenn der Greiferträger 1, d.h. ein Greiferband 2 und/oder ein Führungsteil 14, verschleißen und somit dünner werden, das in dem Greiferträger 1 vorhandene Identifizierungselement 10 ab einem bestimmten Verschleiß des Greiferträgers 1 mit der Führung 6 und/oder den Führungselementen 8 in Kontakt gerät. Ab diesem Zustand wird das Identifizierungselement 10 ebenfalls einem Verschleiß ausgesetzt, so dass es beschädigt wird und seine Identifizierungsfunktion verliert. Dieser Funktionsausfall wird von der Erfassungsvorrichtung 12 erkannt. Die Beschädigung kann bei einer kurzgeschlossenen Spule durch das Durchscheuern eines Leiters der Spule 11 und bei einem RFID-Transponder 15 durch das Wegscheuern eines Teils verursacht werden.The invention assumes that when the gripper carrier 1, ie a

Wenn beispielsweise das Identifizierungselement 20 beschädigt wird und seine Identifizierungsfunktion verliert, das näher an der Unterseite des Greiferbandes 2 und näher an der Unterseite des Führungsteils 14 angeordnet ist, so kann die Steuer- und Regeleinheit 16 das so auswerten, dass das Greiferband 2 oder das Führungsteil 14 zwar verschlissen, jedoch noch nicht vollständig verschlissen sind. Die Steuer- und Regeleinheit 16 kann dann ein Signal generieren, das anzeigt, dass das Greiferband 2 und/oder das Führungsteil 14 demnächst ausgewechselt werden müssen. Wenn dann danach auch ein Identifizierungselement 10 beschädigt wird, das weiter von der Unterseite entfernt ist, so wird das Signal erzeugt, dass ein Auswechseln erfolgen muss. Dabei kann beispielsweise die Greiferwebmaschine durch dieses Signal gestoppt werden. Bei abgewandelten Ausführungsformen wird vorgesehen, dass das Greiferband 2 und/oder das Führungsteil 14 mehr als zwei Identifizierungselemente 10, 20 enthalten.For example, if the

Bei einer nicht dargestellten Ausführungsform wird das Identifizierungselement 10 nicht nur durch einen Kondensator 21, sondern durch einen elektrischen Widerstand, durch eine Diode, durch einen Transistor oder andere elektrische Elemente oder durch eine andere elektrische Schaltung ersetzt. Ein derartiges Identifizierungselement 10 ist dann so konzipiert, dass bei einer bestimmten Bewegungsgeschwindigkeit dieses I-dentifizierungselements 10 ein dieser Bewegungsgeschwindigkeit entsprechendes Signal mit Hilfe der Erfassungsvorrichtung 12 generiert wird.In one embodiment, not shown, the
Bei einer abgewandelten Ausführungsform ist die Erfassungsvorrichtung 12 nicht im Bereich des Führungselementes 6 angeordnet, sondern im Bereich eines der Führungselemente 8. Falls die Erfassungsvorrichtung 12 im Bereich eines Führungselementes 8 angeordnet ist, dass sich in der Nähe der Übergabeposition von einem Gebergreifer zu einem Nehmergreifer befindet, kann mit der Erfassungsvorrichtung 12 auch der Zeitpunkt der Schussfadenübergabe erfasst werden.In a modified embodiment, the
Wenn mehrere Identifizierungselemente 10 oder 20 vorgesehen werden, so können auch mehrere Erfassungsvorrichtungen vorgesehen werden, die jeweils mit einem der Identifizierungselemente 10 oder 20 zusammen arbeiten. Die Erfassungsvorrichtungen können dann an unterschiedlichen Stellen angeordnet sein, beispielsweise eine Erfassungsvorrichtung 12 im Bereich des Führungselementes 6 und eine andere Erfassungsvorrichtung 12 im Bereich eines Führungselementes 8.If a plurality of
Es ist möglich, die Erfassung des Verschleißes bei jedem Schusseintrag vorzunehmen. Selbstverständlich ist dies nicht zwingend. Eine Erfassung kann auch immer nur dann erfolgen, wenn die Greiferwebmaschine langsam betrieben wird, beispielsweise bei der Reparatur eines Schussfadens. Der kritische Verschleißwert oder Verschleißzustand von Greiferbändern 2 und/oder Führungsteilen 14 ergibt sich nach einer Betriebszeit von 1000 oder mehr Stunden. Es ist deshalb nicht erforderlich, den Verschleißzustand bei jedem Schusseintrag zu kontrollieren. Es genügt, den Verschleiß nur in bestimmten Zeitabständen zu kontrollieren, beispielsweise nach einer wählbaren Anzahl von Betriebsstunden.It is possible to record the wear on each weft insertion. Of course, this is not mandatory. Detection can only take place when the rapier loom is operated slowly, for example when repairing a weft thread. The critical wear value or state of wear of
Der Vorteil eines Greiferträgers 1 mit einem erfindungsgemäßen Identifizierungselement 10, 20 besteht in dem geringen Preis des Identifizierungselementes 10, 20 und in seinem geringen Gewicht. Das Identifizierungselement 10, 20 kann in einfacher Weise an die Form des Greiferträgers 1 angepasst werden und in jedes Greiferband 2 oder jedes Führungsteil 14 integriert werden. Darüber hinaus erfolgt eine berührungslose Erfassung des Verschleißes, wodurch die Erfassungsvorrichtung praktisch keinen Einfluss auf den Greiferträger 1 hat. Der Abstand zwischen der Erfassungsvorrichtung 12 und dem Identifizierungselement 10, 20 ist unkritisch und kann relativ groß gewählt werden, d.h. in der Größenordnung von mehreren Millimetern. Eine derartige Erfassungsvorrichtung 12 und derartige Identifizierungselemente 10, 20 sind unempfindlich gegenüber Staub, wodurch sie für Greiferwebmaschinen sehr geeignet sind.The advantage of a gripper carrier 1 with an
Mittels der Erfindung kann für jeden Greiferträger exakt bestimmt werden, wann sein Verschleiß so stark ist, dass er ausgewechselt werden muss. Dadurch ist es möglich, den Greiferträger 1 solange wie möglich einzusetzen. Das ist gegenüber einem Verfahren vorteilhaft, bei welchem jeder Greiferträger grundsätzlich nach einer bestimmten Betriebsstundenzahl ausgewechselt wird. Durch die Erfindung wird einerseits ein vorzeitiger Verschleiß eines Greiferträgers 1 rechtzeitig festgestellt, so dass ein Bruch des Greiferträgers 1 vermieden werden kann. Andererseits wird ein länger haltbarer Greiferträger 1 so lange wie möglich eingesetzt.By means of the invention it can be determined exactly for each gripper carrier when its wear is so strong that it has to be replaced. This makes it possible to use the gripper carrier 1 as long as possible. This is advantageous over a method in which each gripper carrier is basically replaced after a certain number of operating hours. By the invention, on the one hand premature wear of a gripper carrier 1 is detected in good time, so that a breakage of the gripper carrier 1 can be avoided. On the other hand, a longer lasting gripper carrier 1 is used as long as possible.
Die Erfindung bietet weiter den Vorteil, dass auch andere Funktionen realisierbar sind. Beispielsweise kann nicht nur der Verschleiß eines Greiferträgers 1 festgestellt werden. Es ist auch möglich, die Position des Greiferträgers 1 in Bezug auf die Winkelposition des Antriebsrades 3 zu erfassen. Dabei kann beispielsweise mittels der Steuer- und Regeleinheit 16 der Greiferwebmaschine die Winkelposition des Antriebsrades 3 gespeichert werden, bei der sich das Identifizierungselement der Erfassungsvorrichtung 12 gegenüber befindet. Damit kann beim Weben erkannt werden, ob ein Greiferband gerissen ist und/oder ob ein Greiferband 2 korrekt angebracht worden ist, indem überprüft wird, ob das Signal der Erfassungsvorrichtung 12 bei einer Sollwinkelposition des Antriebsrades 3 generiert wird. Dadurch ist es möglich, Greiferband 2 und/oder Antriebsrad 3 nach dem Einbau eines neuen Greiferbandes 2 im Hinblick auf den Antrieb dieses Greiferbandes 2 korrekt einzustellen, so dass auch die Position des Greifers 9 in Bezug zur Winkelposition der Greiferwebmaschine eingestellt werden kann.The invention further offers the advantage that other functions can be realized. For example, not only the wear of a gripper carrier 1 can be determined. It is also possible to detect the position of the gripper carrier 1 with respect to the angular position of the
Bei der Verwendung eines Transponders, insbesondere eines RFID-Transponders 15, der Daten über die Eigenschaften des Greiferbandes 2 und/oder des Führungsteils 14 enthält, kann das Signal dieses RFID-Transponders 15 auch verwendet werden, um bestimmte Einstellungen der Greiferwebmaschine automatisch vorzunehmen. Beispielsweise kann der RFID-Transponder 15 des Führungsteils 14 und/oder des Greiferbandes 2 Daten enthalten, die eine automatische Einregelung der Drehzahl der Greiferwebmaschine ermöglichen. Die Daten dieses RFID-Transponders 15 können beispielsweise dann ausgelesen werden, wenn die Greiferwebmaschine im Kriechgang betrieben wird, da dieses Auslesen nicht bei jedem Schusseintrag erforderlich ist. Die Daten des RFID-Transponders 15, die auch Informationen über die Gestalt, das Material oder andere Eigenschaften sein können, können auch auf dem Display 17 der Greiferwebmaschine angezeigt werden, so dass abgelesen werden kann, welcher Typ Greiferband 2 oder welcher Typ Führungsteil 14 in die Webmaschine eingebaut sind. Dadurch ist es möglich, zu erkennen, wie lange ein Greiferband 2 oder ein Führungsteil 14 in der Webmaschine waren und wie lange mit ihnen gewoben wurde. Die Daten zu dem Greiferband 2 und/oder dem Führungsteil 14 können auch verwendet werden, um zu erkennen, durch welches Greiferband 2 und/oder welches Führungsteil 14 ein verschlissenes Greiferband 2 und/oder ein verschlissenes Führungsteil 14 ersetzt werden müssen. Ebenso ist es möglich, zu überprüfen, ob ein neuen Greiferband 2 und/oder ein neues Führungsteil 14 mit dem verschlissenen Greiferband 2 und/oder verschlissenen Führungsteil 14 identisch ist.When using a transponder, in particular an

Bei einer abgewandelten Ausführungsform der Erfindung wird jeder Verschleißfläche eines Greiferträgers 1, d.h. eines Greiferbandes 2 und/oder eines Führungsteils 14, ein Identifizierungselement 10, 20 zugeordnet, um erkennen zu können, ob ein Verschleiß an einer der Verschleißflächen bereits so groß ist, dass der Greiferträger 1 ausgewechselt werden muss.In a modified embodiment of the invention, each wear surface of a gripper carrier 1, i. a

Sie können im Rahmen der Ansprüche in verschiedenen Ausführungen und in unterschiedlichen Kombinationen der dargestellten Ausführungsbeispiele verwirklicht werden. Insbesondere kann als Greiferträger 1 auch eine Greiferstange vorgesehen werden.Of course, the device according to the invention, the method according to the invention and the gripper carrier according to the invention are not limited to the embodiments described as examples and illustrated in the drawings. They can be realized within the scope of the claims in various embodiments and in different combinations of the illustrated embodiments. In particular, a gripper bar can also be provided as gripper carrier 1.
