Description

Die Erfindung betrifft eine Kettenwirkmaschine mit einem Wirkbereich, einer Steuereinrichtung, die den Wirkbereich steuert, und einer Bedienungseinrichtung, die leitungslos mit der Steuereinrichtung verbunden ist.The invention relates to a warp knitting machine having an effective range, a control device which controls the effective range, and an operating device, which is connected to the control device without a line.

Eine derartige Kettenwirkmaschine ist aus CN 104131410 B bekannt.Such a warp knitting machine is made CN 104131410 B known.

Eine Kettenwirkmaschine benötigt üblicherweise eine Bedienungseinrichtung, mit der u.a. Einstellarbeiten vorgenommen werden können. Dies wird vielfach dadurch realisiert, dass die Bedienungseinrichtung ein Anzeige- und Eingabegerät umfasst, das innerhalb eines zur Maschine zugehörigen Schaltschranks angeordnet ist.A warp knitting machine usually requires an operating device, with the u.a. Adjustments can be made. This is in many cases realized in that the operating device comprises a display and input device which is arranged within a cabinet associated with the machine.

Wenn ein Bediener beim Einrichten der Kettenwirkmaschine bestimmte Teile der Kettenwirkmaschine beobachten muss, ist eine derartige Anordnung umständlich. Hier ist eine mobile Bedienungseinrichtung, die leitungslos mit der Steuereinrichtung verbunden ist, von Vorteil. Die Bedienungsperson kann dann die Bedienungseinrichtung mit an eine geeignete Position nehmen und dort die gewünschten oder notwendigen Einstellarbeiten vornehmen.When an operator must observe certain parts of the warp knitting machine when setting up the warp knitting machine, such an arrangement is cumbersome. Here is a mobile control device, which is connected without wires to the control device, an advantage. The operator can Then take the operating device to a suitable position and make the desired or necessary adjustments there.

Wenn die Bedienungseinrichtung leitungslos mit der Steuereinrichtung verbunden ist, ist es vielfach erforderlich, eine derartige Verbindung zunächst aufzubauen. Dies gilt insbesondere dann, wenn in einer Fabrikhalle beispielsweise mehrere Kettenwirkmaschinen vorhanden sind. In diesem Fall muss die Verbindung so aufgebaut werden, dass die Bedienungseinrichtung eine bestimmte Kettenwirkmaschine ansprechen kann. Wenn die Einstellarbeiten beendet sind, muss die Verbindung wieder abgebaut werden, um zu vermeiden, dass die Bedienungsperson, die später an einer benachbarten Maschine tätig ist, immer noch eine zuvor eingestellte Maschine mit Einstelldaten beaufschlagt.If the operating device is connected to the control device without cables, it is often necessary to initially set up such a connection. This applies in particular if, for example, several warp knitting machines are present in a factory hall. In this case, the connection must be made so that the operator can address a particular warp knitting machine. When the adjustments have been completed, the connection must be disconnected again to prevent the operator, who later works on a neighboring machine, from still setting data to a previously set machine.

DE 10 2009 022 190 A1 zeigt eine als Spinnmaschine ausgebildete Textilmaschine, die eine Steuereinheit aufweist, die über ein Kommunikationsmittel mit einer Bedieneinheit kommuniziert. Die Bedieneinheit enthält ein Mittel zur Positionserkennung, das die Position der Bedieneinheit in Bezug zur einer Bearbeitungsstelle der Textilmaschine drahtlos erkennt. Die Mittel zur Positionserkennung können einen Sender und einen Empfänger aufweisen. DE 10 2009 022 190 A1 shows a formed as a spinning machine textile machine having a control unit which communicates via a communication means with an operating unit. The operating unit contains a means for detecting the position, which detects the position of the operating unit with respect to a processing point of the textile machine wirelessly. The position detection means may comprise a transmitter and a receiver.

WO 2013/167380 A2 beschreibt eine Vorrichtung mit einer tragbaren Bedieneinheit für eine Gruppe von als Webmaschinen ausgebildeten Textilmaschinen. Eine Bedieneinheit ist vorgesehen, die mit Mitteln zur Erzeugung eines Identifizierungskennzeichens ausgestattet ist und die mit den einzelnen Textilmaschinen jeweils drahtlos verbunden werden kann. Empfänger und Sender an der Bedieneinheit und an der Textilmaschine sind so angepasst, dass eine Verbindung erst aufgebaut wird, wenn eine maximal zulässige Distanz zwischen der Textilmaschine und der tragbaren Bedieneinheit unterschritten wird. WO 2013/167380 A2 describes a device with a portable operating unit for a group of weaving machines designed as textile machines. An operating unit is provided which is equipped with means for generating an identification mark and which can be connected wirelessly to the individual textile machines. Receiver and transmitter on the control unit and on the textile machine are adapted so that a connection is only established when a maximum allowable distance between the textile machine and the portable control unit is reached.

EP 2 966 205 A2 zeigt eine Rundstrickmaschine mit einer Maschinensteuerungseinrichtung, die eine Schnittstelle zum drahtlosen und/oder drahtgebundenen Anschließen mobiler Eingabegeräte aufweist. Die drahtlosen Kommunikationseinrichtungen haben eine Reichweite von kleiner oder gleich 2,5 m. Die Schnittstelle kann über einen Zugangscode ansteuerbar sein. EP 2 966 205 A2 shows a circular knitting machine with a machine control device having an interface for wireless and / or wired connection of mobile input devices. The wireless communication devices have a range of less than or equal to 2.5 m. The interface can be controlled via an access code.

Der Erfindung liegt die Aufgabe zugrunde, Einstellarbeiten an einer Kettenwirkmaschine einfach und sicher zu gestalten.The invention has for its object to make adjustments to a warp knitting machine easily and safely.

Diese Aufgabe wird bei einer Kettenwirkmaschine der eingangs genannten Art dadurch gelöst, dass mindestens eine Sicherheitseinrichtung an der Kettenwirkmaschine vorgesehen ist, die ein Sicherheitssignal sendet, wobei eine Verbindung zwischen der Bedienungseinrichtung und der Steuervorrichtung nur möglich ist, solange die Bedienungseinrichtung das Sicherheitssignal empfängt, wobei die Sicherheitseinrichtung eine begrenzte Reichweite aufweist, wobei die Steuereinrichtung bestimmte Funktionen der Kettenwirkmaschine sperrt, wenn sich eine Bedienungseinrichtung in der Reichweite der Sicherheitseinrichtung befindet.This object is achieved in a warp knitting machine of the type mentioned above in that at least one safety device is provided on the warp knitting machine, which transmits a safety signal, wherein a connection between the operating device and the control device is only possible as long as the operating device receives the safety signal, wherein the Safety device has a limited range, the control device locks certain functions of the warp knitting machine when an operating device is within range of the safety device.

Die Sicherheitseinrichtung kann damit gewährleisten, dass eine Bedienungsperson tatsächlich nur mit einer bestimmten Kettenwirkmaschine kommunizieren kann, um sie beispielsweise einzustellen. Eine Kommunikation mit einer anderen Kettenwirkmaschine ist nicht möglich, wenn die Bedienungseinrichtung das entsprechende Sicherheitssignal nicht mehr empfängt.The safety device can thus ensure that an operator can actually communicate only with a specific warp knitting machine in order to set it, for example. Communication with another warp knitting machine is not possible if the operating device no longer receives the corresponding safety signal.

Die begrenzte Reichweite der Sicherheitseinrichtung ist eine relativ einfache Maßnahme, um sicherzustellen, dass die Bedienungseinrichtung das entsprechende Sicherheitssignal nur dann empfangen kann, wenn die entsprechende Bedienungsperson tatsächlich an der entsprechenden Kettenwirkmaschine tätig ist. Sobald sich die Bedienungsperson mit der Bedienungseinrichtung von der entsprechenden Kettenwirkmaschine entfernt und die Reichweite verlässt, kann die Bedienungseinrichtung das Sicherheitssignal nicht mehr empfangen und die Kommunikation zwischen der Bedienungseinrichtung und der Steuereinrichtung der Kettenwirkmaschine wird unterbrochen oder sie wird nach einer Unterbrechung nicht mehr wiederhergestellt.The limited range of the safety device is a relatively simple measure to ensure that the operator can receive the corresponding safety signal only if the corresponding operator actually operates on the corresponding warp knitting machine. As soon as the operator with the operating device moves away from the corresponding warp knitting machine and leaves the reach, the operating device can no longer receive the safety signal and the communication between the operating device and the control device of the warp knitting machine is interrupted or it is not restored after an interruption.

Mit dem Sperren von Funktionen während sich die Bedienungseinrichtung in der Reichweite der Sicherheitseinrichtung befindet, ergibt sich ein Schutz von Bedien- oder Servicepersonen, die sich in einem Gefahrenbereich der Kettenwirkmaschine aufhalten. So kann beispielsweise ein unbeabsichtigter Maschinenstart verhindert oder blockiert werden. Die Information, ob sich eine Bedienungseinrichtung in der Reichweite der Sicherheitseinrichtung befindet, kann auf unterschiedliche Weise gewonnen werden. Eine Möglichkeit besteht darin, dass die Bedienungseinrichtung dann, wenn sie in die Reichweite gelangt und somit das Sicherheitssignal empfängt, eine entsprechende Information an die Sicherheitseinrichtung übermittelt. Eine andere Möglichkeit besteht darin, dass die Sicherheitseinrichtung selbst feststellt, dass ihr Signal von einer Bedienungseinrichtung empfangen wird. Diese Aufzählung ist nicht abschließend.With the locking of functions while the operating device is within reach of the safety device, there is a protection of operators or service people who are in a hazardous area of the warp knitting machine. For example, an unintentional machine start can be prevented or blocked. The information as to whether an operating device is within the range of the safety device can be obtained in different ways. One possibility is that the operating device, when it reaches the range and thus receives the safety signal, transmits corresponding information to the safety device. Another possibility is that the safety device itself determines that its signal is received by an operator. This list is not exhaustive.

In einer vorteilhaften Ausgestaltung ist vorgesehen, dass die Sicherheitseinrichtung das Sicherheitssignal im betriebsbereiten Zustand permanent sendet. Damit entstehen keine Sicherheitslücken. Man muss nicht mehr darauf achten, dass die Sicherheitseinrichtung zunächst in einen Sicherheitsmodus versetzt wird.In an advantageous embodiment, it is provided that the safety device permanently transmits the safety signal in the ready state. There are no security holes. It is no longer necessary to ensure that the safety device is initially placed in a safety mode.

Vorzugsweise ist die Reichweite einstellbar. Man kann dann die Reichweite an die Gegebenheiten in einer Fabrikhalle anpassen, in der mehrere Kettenwirkmaschinen angeordnet sind.Preferably, the range is adjustable. You can then adjust the range to the conditions in a factory hall in which several warp knitting machines are arranged.

Vorteilhafterweise ist die Sicherheitseinrichtung mit der Kettenwirkmaschine verbunden. Dies hält das Risiko von Fehlern klein, weil man die Sicherheitseinrichtung nicht von der Kettenwirkmaschine entfernen kann. Unter "verbunden" soll auch verstanden werden, dass die Sicherheitseinrichtung auf der Kettenwirkmaschine aufliegt oder auf andere Weise an der Kettenwirkmaschine positioniert wird.Advantageously, the safety device is connected to the warp knitting machine. This keeps the risk of errors small, because you can not remove the safety device from the warp knitting machine. By "connected" is also to be understood that the safety device rests on the warp knitting machine or is positioned in any other way on the warp knitting machine.

In einer vorteilhaften Ausgestaltung sind mehrere Sicherheitseinrichtungen vorgesehen, die an verschiedenen Positionen an der Kettenwirkmaschine angeordnet sind. Dies ist insbesondere dann von Vorteil, wenn die Reichweite kleiner ist als die Abmessung der Kettenwirkmaschine. Man kann dann alle Bereiche der Kettenwirkmaschine mit der Bedienungseinrichtung erreichen, ohne dass es notwendig ist, die Reichweite einer einzelnen Steuereinrichtung zu vergrößern.In an advantageous embodiment, a plurality of safety devices are provided, which are at different positions on the warp knitting machine are arranged. This is particularly advantageous when the range is smaller than the dimension of the warp knitting machine. One can then reach all areas of the warp knitting machine with the operating device, without it being necessary to increase the range of a single control device.

Hierbei ist bevorzugt, dass mindestens eine Sicherheitseinrichtung zusätzlich zum Sicherheitssignal Informationen sendet, die ihrer Position an der Kettenwirkmaschine zugeordnet sind. Wenn die Kettenwirkmaschine beispielsweise als Multiaxialmaschine ausgebildet ist, die mehrere Leger aufweist, dann sind an den Legern andere Einstellarbeiten vorzunehmen, als im Wirkbereich. Die positionsbezogenen Informationen können dann verwendet werden, um an den Legern nur solche Einrichtungsmöglichkeiten anzuzeigen, die den Leger betreffen, und am Wirkbereich nur solche Einrichtungsmöglichkeiten, die den Wirkbereich betreffen. In einem solchen Fall kann es von Vorteil sein, wenn sich die Reichweiten der unterschiedlichen Sicherheitseinrichtungen nicht überlappen.It is preferred that at least one safety device sends information in addition to the safety signal, which are assigned to their position on the warp knitting machine. If the warp knitting machine is designed, for example, as a multi-axial machine which has a plurality of markers, other adjustments must be made to the markers than in the effective area. The position-related information can then be used to indicate to the viewers only those facility options that affect the layer, and only those facility facilities that affect the effective area at the effective area. In such a case, it may be advantageous if the ranges of the different safety devices do not overlap.

Vorteilhafterweise sendet mindestens eine Sicherheitseinrichtung zusätzlich zum Sicherheitssignal Informationen, die einem aktuellen Betriebszustand der Kettenwirkmaschine zugeordnet sind. Wenn sich beispielsweise die Kettenwirkmaschine im "Einrichtbetrieb" befindet, können passende Einrichtdialoge angezeigt werden.Advantageously, at least one safety device transmits, in addition to the safety signal, information which is assigned to a current operating state of the warp knitting machine. If, for example, the warp knitting machine is in "set-up mode", suitable setup dialogs can be displayed.

In einer vorteilhaften Ausgestaltung ist vorgesehen, dass die Sicherheitseinrichtung als Kommunikationsvermittlungseinrichtung ausgebildet ist und das Sicherheitssignal Kommunikationsaufbaudaten enthält. Das Sicherheitssignal wird in diesem Fall zwar etwas komplizierter, weil es mehr Informationen enthält. Die Bedienungsperson kann aber entlastet werden, weil sie die Kommunikationsaufbaudaten nicht mehr in die Bedienungseinrichtung eingeben muss.In an advantageous embodiment, it is provided that the safety device is designed as a communication switching device and the safety signal contains communication structure data. The safety signal in this case is a bit more complicated because it contains more information. However, the operator can be relieved because they no longer need to enter the communication setup data in the operating device.

Vorzugsweise ist die leitungslose Verbindung eine WLAN-Verbindung und die Kommunikationsaufbaudaten enthalten Zugangsdaten für einen der Kettenwirkmaschine zugeordneten Anschlusspunkt. Eine WLAN-Verbindung, also eine "Wireless Local Area Network-Verbindung" ist ein eingeführter Standard. Man benötigt hier für einen Verbindungsaufbau in der Regel Zugangsdaten in Form eines Benutzernamens und eines Passworts. Der Anschlusspunkt ist einer speziellen Kettenwirkmaschine zugeordnet, so dass man über den Benutzernamen und das Passwort eine bestimmte Kettenwirkmaschine eindeutig identifizieren kann. Ein Anschlusspunkt einer normalen WLAN-Verbindung hat aber üblicherweise eine relativ große Reichweite, die mehrere zehn Meter oder sogar hundert Meter umfasst, so dass dann, wenn die Bedienungsperson es versäumt, die WLAN-Verbindung nach erfolgten Einstellarbeiten zu trennen, immer das Risiko besteht, dass die Bedienungsperson beim Einstellen einer weiteren Maschine immer noch die zuvor eingestellte Maschine beeinflusst. Mit dem Sicherheitssignal ist dieses Risiko ganz erheblich vermindert. Die WLAN-Verbindung wird automatisch eingerichtet und, wenn die Bedienungseinrichtung aus der Reichweite der Sicherheitseinrichtung heraus bewegt wird, auch automatisch wieder getrennt.Preferably, the wireless connection is a WLAN connection and the communication setup data includes access data for a connection point associated with the warp knitting machine. A wireless connection, ie a "wireless local area network connection" is an established standard. In this case, access data in the form of a user name and a password is usually required to establish a connection. The connection point is assigned to a special warp knitting machine so that a specific warp knitting machine can be uniquely identified via the user name and password. However, a connection point of a normal Wi-Fi connection usually has a relatively long range, which covers several tens of meters or even hundreds of meters, so that if the operator fails to disconnect the WLAN connection after adjustments have been made, there is always a risk that the operator still influences the previously set machine when setting another machine. The safety signal significantly reduces this risk. The WLAN connection is set up automatically and, if the operating device is moved out of the range of the security device, also automatically disconnected.

Vorzugsweise ist die Bedienungseinrichtung ein mobiles Endgerät, insbesondere in Form eines Mobiltelefons oder eines Tablet-PCs. Derartige mobile Endgeräte weisen eine Anzeigemöglichkeit in Form eines Displays auf. Ferner ist eine Eingabemöglichkeit gegeben, beispielsweise in Form einer Tastatur oder in Form eines berührungsempfindlichen Bildschirms.Preferably, the operating device is a mobile terminal, in particular in the form of a mobile phone or a tablet PC. Such mobile devices have a display capability in the form of a display. Furthermore, an input possibility is given, for example in the form of a keyboard or in the form of a touch-sensitive screen.

Hierbei ist bevorzugt, dass das mobile Endgerät eine Anwendung aufweist, die eine Verbindung zu der Steuereinrichtung nur dann herstellt und aufrechterhält, solange sie das Sicherheitssignal erhält. Eine derartige Anwendung, die oft auch als "App" bezeichnet wird, arbeitet dann als Sicherheitsfunktion, um sicherzustellen, dass Einstellarbeiten an der Kettenwirkmaschine nur dann vorgenommen werden können, wenn die Bedienungseinrichtung innerhalb der Reichweite der Sicherheitseinrichtung positioniert ist.In this case, it is preferred that the mobile terminal has an application which establishes and maintains a connection to the control device only as long as it receives the security signal. Such an application, which is often referred to as "App", then works as Safety function to ensure that adjustments to the warp knitting machine can only be made if the operating device is positioned within the reach of the safety device.

Die Erfindung wird im Folgenden anhand von bevorzugten Ausführungsbeispielen in Verbindung mit der Zeichnung beschrieben. Hierin zeigen:

The invention will be described below with reference to preferred embodiments in conjunction with the drawing. Herein show:

Fig. 1 und 2 zeigen rein schematisch eine Kettenwirkmaschine 1 mit einem Wirkbereich 2 und einer Steuereinrichtung 3. Die Steuereinrichtung 3 steuert den Wirkbereich 2. Die Steuereinrichtung 3 ist mit einem Display 4 und Bedienelementen 5 versehen, so dass eine Bedienungsperson gewisse Einstellarbeiten an der Kettenwirkmaschine 1 vornehmen kann. Fig. 1 and 2 purely schematically show a warp knitting machine 1 with an effective range 2 and a control device 3. The control device 3 controls the effective range 2. The control device 3 is provided with a display 4 and controls 5, so that an operator can make certain adjustments to the warp knitting machine 1.

Um Einstell- oder Bedienungstätigkeiten an anderer Position vornehmen zu können, ist eine Bedienungseinrichtung 6 vorhanden (Fig. 2), die leitungslos mit der Steuereinrichtung 3 verbunden ist. Die leitungslose Verbindung erfolgt im vorliegenden Fall über eine WLAN Verbindung, also ein "Wireless Local Area Network"-Verbindung. Hierzu weist die Kettenwirkmaschine 1 an ihrem Maschinengestell 7 eine Antenne 8 auf und die Bedienungseinrichtung weist eine entsprechende Antenne 9 auf. Die Antennen 8, 9 sind hier als Elemente dargestellt, die außen an den Maschinenrahmen 7 bzw. an die Bedienungseinrichtung 6 angesetzt sind. Die Antennen 8, 9 können aber auch in den Maschinenrahmen 7 bzw. die Bedienungseinrichtung 6 integriert sein.In order to be able to carry out setting or operating activities at another position, an operating device 6 is present ( Fig. 2 ), which is connected without wires to the control device 3. The wireless connection takes place in the present case via a WLAN connection, ie a "Wireless Local Area Network" connection. For this purpose, the warp knitting machine 1 has an antenna 8 on its machine frame 7 and the operating device has a corresponding antenna 9. The antennas 8, 9 are shown here as elements, which are attached to the outside of the machine frame 7 and to the operating device 6. However, the antennas 8, 9 can also be integrated in the machine frame 7 or the operating device 6.

Zusätzlich weist die Kettenwirkmaschine 1 eine Sicherheitseinrichtung 10 auf, die ebenfalls mit einer Antenne 11 versehen ist. Die Sicherheitseinrichtung 10 sendet im betriebsbereiten Zustand, also wenn sie eingeschaltet ist bzw. wenn die Kettenwirkmaschine 1 eingeschaltet ist und damit auch die Sicherheitseinrichtung 10 mit elektrischer Energie versorgt wird, ein Sicherheitssignal aus. Dieses Sicherheitssignal wird permanent ausgesendet.In addition, the warp knitting machine 1 has a safety device 10, which is also provided with an antenna 11. The safety device 10 sends in the ready state, so when it is turned on or when the warp knitting machine 1 is turned on and thus the safety device 10 is supplied with electrical energy, a safety signal. This safety signal is transmitted permanently.

Mit einem gestrichelt dargestellten Kreis 12 ist die Reichweite der Sicherheitseinrichtung 10 begrenzt. Sie ist einstellbar, so dass man die Reichweite an verschiedene Gegebenheiten anpassen kann. Die Sicherheitseinrichtung ist in den Ausführungsbeispielen der Fig. 1 bis 3 mit der Kettenwirkmaschine 1, genauer gesagt mit dem Maschinengestell 7 der Kettenwirkmaschine 1 verbunden.With a dashed circle 12, the range of the safety device 10 is limited. It is adjustable, so you can adjust the range to different conditions. The safety device is in the embodiments of Fig. 1 to 3 with the warp knitting machine 1, more specifically connected to the machine frame 7 of the warp knitting machine 1.

Die Bedienungseinrichtung 6 weist eine Antenne 11a zum Empfang des Sicherheitssignals auf. Die Antenne 11a ist hier als getrenntes Element dargestellt. Üblicherweise wird aber die Funktion der Antenne 11a auch von der Antenne 9 übernommen.The operating device 6 has an antenna 11a for receiving the security signal. The antenna 11a is shown here as a separate element. Usually, however, the function of the antenna 11a is also taken over by the antenna 9.

Die Bedienungseinrichtung 6 kann nun eine Verbindung zur Steuereinrichtung 3 nur dann herstellen, wenn sie das Sicherheitssignal von der Sicherheitseinrichtung 10 empfängt. Die Bedienungseinrichtung 6 muss sich also innerhalb der durch den Kreis 12 dargestellten Reichweite befinden, damit eine Bedienungsperson Einstellarbeiten an der Kettenwirkmaschine 1 vornehmen kann. Sobald die Bedienungsperson sich mit der Bedienungseinrichtung 6 aus dem Kreis 12 herausbewegt, wird die Verbindung zwischen der Bedienungseinrichtung 6 und der Steuereinrichtung 3 unterbrochen, so dass sichergestellt ist, dass die Bedienungsperson nicht versehentlich weitere Einstellarbeiten vornehmen kann, was beispielsweise dann passieren kann, wenn die Bedienungsperson zu einer anderen Kettenwirkmaschine geht und dort weitere Einstellarbeiten vornehmen möchte. Man kann vorsehen, dass die Kettenwirkmaschine 1 stoppt, wenn die Verbindung unterbrochen wird und sich die Kettenwirkmaschine 1 im Einstellbetrieb befindet. Die Kettenwirkmaschine 1 wird beispielsweise nicht gestoppt, wenn die Verbindung unterbrochen wird und die Kettenwirkmaschine im Produktionsbetrieb arbeitet.The operating device 6 can now establish a connection to the control device 3 only if it receives the safety signal from the safety device 10. The operating device 6 must therefore be within the range shown by the circle 12 so that an operator can make adjustments to the warp knitting machine 1. As soon as the operator moves out of the circuit 12 with the operating device 6, the connection between the operating device 6 and the control device 3 is interrupted, so that it is ensured that the operator can not accidentally make further adjustments, which can happen, for example, if the Operator goes to another warp knitting machine and would like to make there additional adjustments. It can be provided that the warp knitting machine 1 stops when the connection is interrupted and the warp knitting machine 1 is in setting operation. For example, the warp knitting machine 1 is not stopped when the connection is broken and the warp knitting machine is in production.

Man kann die Sicherheitseinrichtung auch für eine Kontrolle in umgekehrter Richtung nutzen. Wenn die Bedienungseinrichtung 6 in die Reichweite der Sicherheitseinrichtung 10 gelangt, dann kann die Steuereinrichtung 3 bestimmte Funktionen der Kettenwirkmaschine sperren. Beispielsweise kann die Steuereinrichtung 3 einen Betrieb oberhalb einer gewissen Drehzahl sperren und nur eine Funktion im Kriechgang zulassen. Damit wird das Risiko einer Gefährdung der Bedienungsperson klein gehalten.You can also use the safety device for a check in the opposite direction. If the operating device 6 comes within the range of the safety device 10, then the control device 3 can lock certain functions of the warp knitting machine. For example, the control device 3 block operation above a certain speed and only allow a function in the crawl. This minimizes the risk of the operator being endangered.

In Fig. 2 ist eine Ausgestaltung dargestellt, bei der eine einzelne Sicherheitseinrichtung 10 die gesamte Länge des Wirkbereichs 2 abdeckt, also den gesamten Raum, in dem sich eine Bedienungsperson aufhalten kann, um Einstellarbeiten vorzunehmen. Dies hat zur Folge, dass der Bereich, innerhalb dessen die Bedienungseinrichtung 6 eine Verbindung zur Steuereinrichtung 3 aufbauen kann, in eine Richtung quer zum Maschinengestell 7 relativ groß wird.In Fig. 2 a configuration is shown in which a single safety device 10 covers the entire length of the effective area 2, ie the entire space in which an operator can be present to make adjustments. This has the consequence that the area within which the operating device 6 can establish a connection to the control device 3, in a direction transverse to the machine frame 7 is relatively large.

Um dies zu verhindern, kann man auch, wie in Fig. 3 dargestellt, mehrere Sicherheitseinrichtungen 10a, 10b, 10c am Maschinengestell 7 anordnen. Jede Sicherheitseinrichtung 10a, 10b, 10c hat dann eine entsprechend kleinere Reichweite, die durch die Kreise 12a, 12b, 12c dargestellt ist. Die Reichweiten überlappen sich geringfügig. Die Überlappung kann auch größer sein als dargestellt. Der Bereich, in dem sich die Bedienungseinrichtung 6 befinden muss, um eine Verbindung mit der Steuereinrichtung 3 aufbauen zu können, und der außerhalb des Maschinenrahmens liegt, wird dadurch erheblich kleiner.To prevent this, you can also, as in Fig. 3 shown, several safety devices 10a, 10b, 10c on the machine frame 7 order. Each safety device 10a, 10b, 10c then has a correspondingly smaller range, which is represented by the circles 12a, 12b, 12c. The ranges overlap slightly. The overlap may also be greater than shown. The area in which the operating device 6 must be in order to establish a connection with the control device 3 can, and which is outside of the machine frame, thereby considerably smaller.

Wie oben erwähnt, wird im vorliegenden Ausführungsbeispiel die Verbindung zwischen der Bedienungseinrichtung 6 und der Steuereinrichtung 3 durch eine WLAN-Verbindung hergestellt. In diesem Fall kann die Sicherheitseinrichtung 10 als Kommunikationsvermittlungseinrichtung ausgebildet sein, die mit dem Sicherheitssignal auch Kommunikationsaufbaudaten übermittelt. Diese Kommunikationsaufbaudaten sind beispielsweise eine Benutzerkennung, die jeder Kettenwirkmaschine 1 einzeln zugeordnet ist, und ein entsprechendes Passwort. Die entsprechenden Kommunikationsaufbaudaten können an die Bedienungseinrichtung 6 übermittelt werden, so dass eine WLAN-Verbindung hergestellt werden kann, ohne dass die Bedienungsperson die entsprechenden Zugangsdaten getrennt eingeben muss. Das Sicherheitssignal kann auch nur aus den Kommunikationsaufbaudaten bestehen.As mentioned above, in the present embodiment, the connection between the operation device 6 and the control device 3 is made by a WLAN connection. In this case, the safety device 10 can be designed as a communication switching device, which also transmits communication setup data with the safety signal. This communication setup data is, for example, a user ID, which is assigned to each warp knitting machine 1 individually, and a corresponding password. The corresponding communication setup data can be transmitted to the operating device 6, so that a WLAN connection can be established without the operator having to enter the corresponding access data separately. The safety signal can only consist of the communication setup data.

Dadurch, dass die Kommunikationsaufbaudaten nur mit einer begrenzten Reichweite gesendet werden, kann, wie oben erläutert, eine Verbindung zwischen der Bedienungseinrichtung 6 und der Steuereinrichtung 3 nur dann zustande kommen, wenn die Bedienungseinrichtung 6 dicht genug an der Kettenwirkmaschine 1 angeordnet wird. Damit wird sichergestellt, dass eine Bedienungsperson, die Einstellarbeiten an einer bestimmten Kettenwirkmaschine vornehmen möchte, tatsächlich nur Einstellarbeiten an dieser Kettenwirkmaschine vornehmen kann und nicht an einer anderen Kettenwirkmaschine, auch wenn die andere Kettenwirkmaschine relativ eng benachbart angeordnet ist.As a result of the communication setup data being sent only with a limited range, as explained above, a connection between the operating device 6 and the control device 3 can only be achieved if the operating device 6 is arranged close enough to the warp knitting machine 1. This ensures that an operator who wants to make adjustments on a particular warp knitting machine can actually make adjustments only on this warp knitting machine and not on another warp knitting machine, even if the other warp knitting machine is arranged relatively close together.

Die Verwendung von mehreren Sicherheitseinrichtungen kann insbesondere bei größeren Maschinen ausgenutzt werden, was anhand von Fig. 4 erläutert werden soll.The use of multiple safety devices can be exploited especially for larger machines, which is based on Fig. 4 should be explained.

Fig. 4 zeigt eine Kettenwirkmaschine 1' in Form einer Multiaxialmaschine. Die Kettenwirkmaschine 1' weist einen Verfestigungsabschnitt 13 und mehrere Leger 14a, 14b und 14c auf. Fig. 4 shows a warp knitting machine 1 'in the form of a multi-axial machine. The warp knitting machine 1 'has a hardening section 13 and a plurality of layers 14a, 14b and 14c.

Die Sicherheitseinrichtungen 10a, 10b, 10c, 10d sind nun so angeordnet, das sich die durch Kreise 12a, 12b, 12c, 12d dargestellten Reichweiten nicht überlappen. Allerdings ist jede Sicherheitseinrichtung 10a, 10b, 10c, 10d einem bestimmten Bereich der Kettenwirkmaschine 1' zugeordnet.The safety devices 10a, 10b, 10c, 10d are now arranged so that the ranges represented by circles 12a, 12b, 12c, 12d do not overlap. However, each safety device 10a, 10b, 10c, 10d is assigned to a specific area of the warp knitting machine 1 '.

Dies kann man ausnutzen, indem mindestens eine der Sicherheitseinrichtungen 10a, 10b, 10c, 10d zusätzlich zum Sicherheitssignal Informationen sendet, die der Position der entsprechenden Sicherheitseinrichtung 10a, 10b, 10c, 10d an der Kettenwirkmaschine 1 zugeordnet sind. Wenn beispielsweise die Bedienungseinrichtung 6 in die Reichweite der Sicherheitseinrichtung 10b gelangt, die dem Leger 14a zugeordnet ist, dann werden auf der Bedienungseinrichtung 6 nur Einstellmöglichkeiten angezeigt, die sich auf den Leger 14a beziehen. In einer Position in der Reichweite der Sicherheitseinrichtung 10b kann die Bedienungsperson ohnehin nur Einstellarbeiten am Leger 14a vornehmen.This can be exploited by sending at least one of the safety devices 10a, 10b, 10c, 10d in addition to the safety signal information associated with the position of the corresponding safety device 10a, 10b, 10c, 10d on the warp knitting machine 1. For example, if the operating device 6 comes within the range of the safety device 10b, which is associated with the Leger 14a, then only settings are displayed on the operating device 6, which relate to the Leger 14a. In a position within reach of the safety device 10b, the operator can only make adjustments to the Leger 14a anyway.

Die Bedienungseinrichtung 6 kann, wie dies in Fig. 2 dargestellt ist, als mobiles Endgerät ausgebildet sein, beispielsweise in Form eines Mobiltelefons oder eines Tablet-PC. Die Bedienungseinrichtung weist eine Anzeige 15 und Bedienungselemente 16 auf. Die Anzeige kann dem Display 4 der Steuereinrichtung 3 entsprechen. Sie kann aber auch anders ausgebildet sein. Die Bedienungselemente 16 können den Bedienungselementen 5 der Steuereinrichtung 3 entsprechen. Es können aber auch andere Bedienungselemente 16 vorgesehen sein. Man kann zusätzlich oder anstelle der Bedienungselemente 16 auch einen berührungsempfindlichen Bildschirm verwenden, um Einstellinformationen eingeben zu können.The operating device 6 can, as in Fig. 2 is shown to be designed as a mobile terminal, for example in the form of a mobile phone or a tablet PC. The operating device has a display 15 and operating elements 16. The display may correspond to the display 4 of the control device 3. But it can also be designed differently. The controls 16 may correspond to the controls 5 of the controller 3. But there are others too Controls 16 may be provided. In addition to or instead of the operating elements 16, it is also possible to use a touch-sensitive screen in order to be able to enter setting information.

Das Bediengerät 6 weist eine Anwendung auf, eine so genannte "APP", die permanent überprüft, ob sich die Bedienungseinrichtung 6 in der Reichweite der Sicherheitseinrichtung 10 bzw. der Sicherheitseinrichtungen 10a, 10b, 10c, 10d befindet. Nur in diesem Fall baut die Anwendung die Verbindung zur Steuereinrichtung 3 auf. Wenn das Sicherheitssignal nicht mehr empfangen wird, wird die Verbindung zur Steuereinrichtung 3 unterbrochen. In manchen Fällen wird die Verbindung zwischen der Bedienungseinrichtung 6 und der Steuereinrichtung 3 auch auf andere Weise, beispielsweise externe Einflüsse, unterbrochen. In diesem Fall verhindert die Anwendung in der Bedienungseinrichtung 6, dass die Verbindung wieder aufgebaut wird, wenn das Sicherheitssignal vom Bediengerät 6 nicht mehr empfangen wird.The operating device 6 has an application, a so-called "APP", which permanently checks whether the operating device 6 is within the range of the safety device 10 or the safety devices 10a, 10b, 10c, 10d. Only in this case does the application establish the connection to the control device 3. If the security signal is no longer received, the connection to the controller 3 is interrupted. In some cases, the connection between the operating device 6 and the control device 3 in other ways, such as external influences, interrupted. In this case, the application in the operating device 6 prevents the connection from being reestablished when the security signal from the operating device 6 is no longer received.

Die Anwendung kann auch entsprechende Anzeigeseiten an die Anzeigeeinrichtung 15 der Bedienungseinrichtung 6 übertragen. Wie oben erwähnt, können diese Anzeigeseiten dann positionsabhängig aufgebaut werden oder auch situationsabhängig. Befindet sich beispielsweise die Kettenwirkmaschine im "Einrichtbetrieb", so könnten passende Einrichtdialoge angezeigt werden, sobald sich eine Bedienungsperson der Kettenwirkmaschine 1, 1' nähert.The application can also transmit corresponding display pages to the display device 15 of the operating device 6. As mentioned above, these display pages can then be constructed depending on the position or depending on the situation. For example, if the warp knitting machine is in "set-up mode", suitable set-up dialogs could be displayed as soon as an operator approaches the warp knitting machine 1, 1 '.
