Description

Die Erfindung betrifft eine Aufspulmaschine zum Aufwickeln eines kontinuierlich anlaufenden Fadens gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a winding machine for winding a continuously starting thread according to the preamble of the claim 1.

Eine derartige Aufspulmaschine ist aus der EP 0 374 536 bekannt. Hierbei werden die Antriebe für die Spulspindel, den Revolver und die Changierung mittels einer Antriebselektronik gesteuert. Darüber hinaus weist die bekannte Aufspulmaschine weitere Elektronikkomponenten auf, die zur Steuerung des Spulvorgangs sowie des Spulenwechsels dienen. Wie beispielsweise aus dem Firmenprospekt der Anmelderin "Elektronik-Systeme, Elektronik-Komponenten" bekannt ist, sind derartige Elektronikkomponenten sowie die Elektrik zur Steuerung der Antriebe in einem Schaltschrank angeordnet, der in der Nähe der Aufspulmaschine aufgestellt ist. Die Bedienung der Aufspulmaschine erfolgt jedoch direkt an der Maschine an einem hierfür vorgesehenen Bedientableau. Es hat sich nun herausgestellt, daß insbesondere zu Diagnosezwecken diese Anordnung zu dem Problem führt, daß die Bedienperson vom Schaltschrank aus nicht den Arbeitsablauf der Maschine steuern kann. Desweiteren ist eine individuelle Einstellung der Antriebsparameter nur bedingt möglich, da die steuerungsrelevanten Parameter aus einer zentralen Maschinensteuerung der Aufspulmaschine vorgegeben werden.Such a winding machine is known from EP 0 374 536. The drives for the winding spindle, the turret and the Traversing controlled by a drive electronics. Furthermore the known winding machine has further electronic components, which are used to control the winding process and the bobbin change. How for example from the company brochure of the applicant "electronics systems, Electronic Components "is known, are such electronic components as well as the electrical system for controlling the drives in a control cabinet arranged, which is placed near the winding machine. However, the winding machine is operated directly on the machine on a dedicated control panel. It has now been found that especially for diagnostic purposes this arrangement to the Problem leads that the operator from the control cabinet not the Can control the workflow of the machine. Furthermore, an individual Adjustment of the drive parameters is only possible to a limited extent because the control-relevant Parameters from a central machine control of the winding machine be specified.

Demgegenüber ist es Aufgabe der Erfindung, eine Aufspulmaschine der eingangs genannten Art derart weiterzubilden, daß die Prozeßsteuerung zentral an der Aufspulmaschine durch eine Bedienperson vorgebbar, veränderbar und prüfbar ist. In contrast, it is an object of the invention, a winding machine type mentioned in such a way that the process control Can be specified centrally on the winding machine by an operator, is changeable and testable.

Ein weiteres Ziel der Erfindung ist es, eine möglichst kurze und kompakte Aufspulmaschine zu schaffen.Another object of the invention is to be as short and compact as possible To create a winding machine.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Antriebselektronik und die Steuerungselektronik zu je einer Elektronikeinheit zusammengefaßt und an dem Träger über eine Teillänge verteilt angeordnet sind. Die Steuerungselektronik umfaßt hierbei die üblicherweise auf Steckkarten integrierten Schaltungen und deren Bauteile. Die Antriebselektronik umfaßt im wesentlichen die zur Energieversorgung der Antriebe erforderlichen Bauteile wie beispielsweise Wechselrichter. Durch die Anordnung der Elektronikeinheiten an dem Träger, an welchem auch das Bedientableau zur Bedienung der Aufspulmaschine angeordnet ist, wird eine zentrale Bedienung der durch die Steuerungselektronik und Antriebselektronik bewirkten Maschinenfunktionen möglich. Die Befestigung der Elektroeinheit an dem Träger, der gleichzeitig die Changierung aufnimmt, führt zu einer sehr kompakten und raumsparenden Bauweise der Aufspulmaschine. Die Elektronikeinheiten sind dabei derart an dem Träger befestigt, daß die im Träger auftretenden Schwingungen nicht zu Störungen des Elektronikaufbaus führen.This object is achieved in that the drive electronics and the control electronics combined to form an electronic unit and arranged on the carrier distributed over a partial length are. The control electronics usually include the Plug-in cards integrated circuits and their components. The drive electronics essentially includes the energy supply for the drives required components such as inverters. Through the Arrangement of the electronics units on the carrier, on which also that Control panel for operating the winding machine is arranged central operation of the control electronics and drive electronics effected machine functions possible. The attachment of the Electrical unit on the carrier, which also receives the traversing, leads to a very compact and space-saving construction of the winding machine. The electronics units are in this way on the carrier attached that the vibrations occurring in the carrier do not cause interference of the electronics assembly.

Eine besonders vorteilhafte Weiterbildung sieht vor, daß im wesentlichen sämtliche Elektronikkomponenten der Aufspulmaschine zu einer Elektronikeinheit zusammengfaßt sind, wobei die Elektronikeinheit einen Zentralprozessor aufweist. Diese Elektronikeinheit ist mit einem Anschluß zur Energieversorgung sowie mit einem Anschluß zum Datentransfer ausgestattet. Der Vorteil dieser erfindungsgemäßen Aufspulmaschine liegt darin, daß die Steuerung durch nur einen Zentralprozessor erfolgt. Damit kann die Aufspulmaschine unabhängig von einer externen zentralen Maschinensteuerung individuell programmiert und betrieben werden. Insbesondere für Diagnose- und Testzwecken ist eine derartige Anordnung vorteilhaft.A particularly advantageous development provides that essentially all electronic components of the winding machine to one electronic unit are summarized, the electronics unit one Central processor has. This electronics unit is with one connector for power supply and with a connection for data transfer fitted. The advantage of this winding machine according to the invention is in that the control is carried out by only one central processor. In order to can the winding machine independently of an external central machine control individually programmed and operated. In particular Such an arrangement is for diagnostic and test purposes advantageous.

Indem alle Elektrofunktionen in einer Einheit zusammengefaßt sind, entfallen doppelt installierte Unterfunktionen, wie z. B. Schnittstellenanschlüsse und Spannungsversorgung. Alle Elektronikfunktionen der Spulmaschine werden somit nur vom Zentralprozessor gesteuert. Die Anbindung an eine externe zentrale Maschinensteuerung, die die Aufspulmaschine einer Anlage überwacht, besteht nur zur Datenübermittlung.By combining all electrical functions in one unit, duplicate installed sub-functions, such as B. Interface connections and power supply. All electronic functions of the The winding machine is therefore only controlled by the central processor. The Connection to an external central machine control system that the winding machine of a plant is only available for data transmission.

Die Anordnung der Elektronikeinheit auf der Bedienseite der Maschine ist insbesondere von Vorteil, um neben der Bedienung auch die Diagnose direkt vom Bedientableau durchzuführen. Dabei kann die Diagnoseinformation direkt auf dem Display des Bedientableaus angezeigt werden.The arrangement of the electronics unit on the operator side of the machine is This is particularly advantageous for the diagnosis as well as the operation to be carried out directly from the control panel. Thereby the diagnostic information are shown directly on the display of the control panel.

Diese Anordnung führt zudem zu einer wesentlichen Erhöhung der Maschinensicherheit, da alle von der Bedienperson auszuführenden Tätigkeiten vor Kopf an der Aufspulmaschine vorgenommen werden können. Der aufgrund der rotierenden Teile besonders gefährliche Bereich an der Längsseite des Spulkopfes braucht von der Bedienperson nicht durchquert werden.This arrangement also leads to a substantial increase in Machine safety as all activities to be performed by the operator can be made in front of the winding machine. The area that is particularly dangerous due to the rotating parts The operator does not need to cross the long side of the winding head become.

Eine weitere vorteilhafte Weiterbildung der Aufspulmaschine sieht vor, daß die Leistungselektronik und die Steuerelektronik in der Elektroeinheit voneinander gekapselt angeordnet sind. Damit läßt sich eine elektrische Abschirmung verwirklichen, so daß eine gegenseitige Beeinflussung bzw. Störung, insbesondere die Einwirkung der Leistungselektronik auf die Steuerelektronik, vermieden wird.Another advantageous development of the winding machine provides that the power electronics and the control electronics in the electrical unit are arranged encapsulated from each other. This can be an electrical Realize shielding so that mutual influence or Disruption, especially the impact of the power electronics on the Control electronics, is avoided.

Die Anordnung der Leistungselektronik an einer mit einem Kühlkörper in wärmeleitendem Kontakt stehenden Platte oder direkt an dem Kühlkörper besitzt den Vorteil, daß die Verlustwärme dort, wo sie entsteht, direkt an die Umgebung abgeführt werden kann. Der Kühlkörper kann hierbei eine Vielzahl von Kühlrippen aufweisen, um eine möglichst große Kühlfläche zu erzeugen. Zur Unterstützung der Kühlwirkung ist es ebenso von Vorteil, wenn der Kühlkörper mittels eines Kühlluftstromes angeblasen wird.The arrangement of the power electronics on a with a heat sink in heat-conducting contact standing plate or directly on the heat sink has the advantage that the heat loss where it arises, directly on the environment can be dissipated. The heat sink can be a A large number of cooling fins have the largest possible cooling surface to create. To support the cooling effect, it is also from Advantage if the cooling body is blown by means of a cooling air flow becomes.

Der Kühlkörper kann vorteilhaft direkt am Träger ausgebildet sein. Beispielsweise könnte der Kühlkörper ein Deckel sein, der einen die Elektronikeinheit aufnehmenden Hohlträger verschließt.The heat sink can advantageously be formed directly on the carrier. For example, the heat sink could be a cover that one Closes electronics unit receiving hollow carrier.

Die Ausbildung des Trägers als U-Profil bietet einen Einbauraum für die Elektronikeinheit ohne zusätzliches Gehäuse.The design of the carrier as a U-profile offers installation space for the Electronics unit without additional housing.

Eine weitere vorteilhafte Ausbildung der Aufspulmaschine ermöglicht es, daß die in jeder Spinnstelle eingesetzten Fadenbruchwächter direkt über eine Signalleitung mit dem Zentralprozessor der Elektroeinheit verbunden ist. Dadurch erfolgt eine Auswertung der Signale direkt in der Aufspulmaschine, so daß eine entsprechend schnelle Reaktion auf etwaige Fadenbrüche erfolgen kann. Des weiteren minimiert sich der Verdrahtungsaufwand zur Überwachung der Fadenbruchwächter, da eine Anbindung an die externe zentrale Maschinensteuerung nicht benötigt wird.A further advantageous embodiment of the winding machine enables that the thread break monitors used in each spinning station are directly above a signal line connected to the central processor of the electrical unit is. This means that the signals are evaluated directly in the winding machine, so that a correspondingly quick reaction to any thread breaks can be done. Furthermore, the wiring effort is minimized to monitor the thread break guard, as a connection to the external central machine control is not required.

Die Spulspindel 2 wird hierbei mittels dem Spindelmotor 4 angetrieben. Die Spulspindel 3 ist mit dem Spindelmotor 5 verbunden. Auf der Spulspindel 2 werden die Spulen 8 gewikkelt. Hierzu läuft in jeder Wickelstelle ein Faden 12 über einen Kopffadenführer 11 zu einer Changiereinrichtung 10. Dem Kopffadenführer 11 ist ein Fadenbruchwächter 13 vorgeschaltet. Die Changiereinrichtung ist an dem Träger 7 befestigt. In Fadenlaufrichtung hinter der Changiereinrichtung läuft der Faden 12 auf eine Andrückwalze 9 auf und wird mittels der Andrückwalze 9 auf der Spulenoberfläche der Spule 8 abgelegt. Hierzu wird die Andrückwalze 9 von dem Faden 12 teilumschlungen. Die Andrückwalze 9 liegt auf der Spulenoberfläche der Spule 8 mit einem bestimmten Anpreßdruck an. Während der Aufspulung wird der Spindelmotor 4 derart geregelt, daß die Umfangsgeschwindigkeit der Spule konstant bleibt. Hierzu wird die Umfangsgeschwindigkeit der Andrückwalze zur Regelung ständig erfaßt. Die dargestellte Aufspulmaschine weist hier insgesamt 6 Aufwickelstellen auf, die alle gleich aufgebaut sind, so daß die Beschreibung analog zu jeder Spinnstelle gilt.The winding machine has a machine frame 1.

The traversing device is on attached to the carrier 7. In the thread running direction behind the traversing device the thread 12 runs on a pressure roller 9 and is by means of the pressure roller 9 placed on the spool surface of the spool 8. For this purpose, the pressure roller 9 is partially wrapped around the thread 12. The Pressure roller 9 lies on the spool surface of spool 8 with a certain contact pressure. During the winding the spindle motor 4 regulated so that the peripheral speed of the coil remains constant. For this purpose, the peripheral speed of the pressure roller for control constantly recorded. The winding machine shown here points here a total of 6 winding stations, all of which are constructed identically, so that the description applies analogously to each spinning station.

Auf der Bedienseite der Aufspulmaschine, von der aus die Spulen 8 nach erfolgter Vollwicklung durch Leerhülsen ausgetauscht werden, weist die Elektronikeinheit 15 ein Bedientableau 16 auf. Die Elektronikeinheit ist mit den Antrieben 4, 5 und 6 durch die Leitungen 35 verbunden. Ebenso ist der Changierantrieb sowie ein Antrieb der Andrückwalze mit der Elektroeinheit verbunden. Eine Signalleitung führt zu den Fadenbruchwächtern 13 zu der Elektronikeinheit.An electrical unit 15 is attached to the carrier 7.
