Description

Machinery for the production or treatment of synthetic threads

The invention relates to a machine installation for the production or treatment of synthetic threads according to the preamble of claim 1.

The manufacturing and treatment of synthetic threads is performed with machinery having a variety of machine components that are divided into machine fields for monitoring and controlling processes. Such a machine system is known for example from WO 2001/069911.

In the known machine system, the individual machine components are each assigned control components which are connected to data exchange within one of the machine fields with adjacent control components. It is customary that the control components are directly linked to the respective machine component. In the production of synthetic threads, the machine components are formed, for example, by godets and on winding machines. Especially with winding machines, it is common that they are replaced at regular intervals for maintenance in the machinery. In this case, all interfaces between the machine component and the machine system must be separable, so that disconnection and re-connection require the shortest possible interruption times. Accordingly, it is an object of the invention to provide a machine system for the production or treatment of synthetic threads, in which machine components with associated control components within the machinery are as fast as possible and trouble-free interchangeable.

This object is achieved according to the invention in that the control components of one of the machine fields are wirelessly connected to one another via a local machine radio network. Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.

The invention has the particular advantage that when replacing the machine components no physical separation between the network and the control component must be made. Due to the stationary coupling of the control component with the machine component, each of the machine components can be flexibly integrated into one of the machine fields. Replacements due to maintenance or repairs of machine components are flexible executable by the wireless connection of the control components via the local machine radio network.

The communication for controlling the machine system can be advantageously further improved by the control components of the adjacent machine fields are wirelessly integrated into the machine radio network. Thus, the control components of all machine fields can communicate with each other, which is particularly advantageous in machine installations in which the machine fields have a plurality of separate similar machine components with separate control components. For the monitoring of the manufacturing or processing process, the development of the invention is particularly advantageous, in which a central operating station is wirelessly integrated into the machine radio network of the control components. There is thus the possibility that an operator directly intervenes in the communication network of the control components in order to trigger, for example, process changes or monitoring functions. For remote monitoring of the machine system, the development of the invention is provided in which the operating station has an Internet interface and in which the operating station is connected to a service station. Thus, the possibility exists that the machine manufacturer analyzes individual machine components within the machine installation directly via a service station. For example, malfunctions of the machine components can be detected early and avoided.

In order to obtain a smooth connection to the process when replacing one of the machine components, the development of the invention is provided in which the control components associated with the machine components each have a component address and a network card for identification. This ensures that the control component can be automatically integrated into the machine radio network.

The machine radio network is preferably carried out according to a WLAN standard. This can on the one hand locally limited frequencies for the On the other hand, high data transmission rates can be realized. The control components can be incorporated equally into the machine radio network. In order to enable the communication between each other and in particular the data transmission between the control components, the development of the invention is provided, in which the machine radio network has one or more base stations. If a base station is used, it is preferably assigned to the operating station, the base station having a router which ensures coordination with the control components.

In very complex machine systems with a large number of machine fields, however, the variant of the invention can also be used in which each of the machine fields has one of the base stations in each case. In this case, the base station is assigned to one of the control components.

For the exchange of data and the fastest possible communication, the formation of control groups comprising a plurality of control components is particularly advantageous. Thus it is possible to combine several control components of similar machine components of several machine fields into a control group. In particular, in the production processes of synthetic threads, for example, the winding machines provided on the winding machines can be combined in a control group.

Alternatively, several control components of one of the machine fields can be combined to form a control group. Such systems are particularly applicable to machinery that perform a single treatment of threads. Thus, several processing points can be arranged in a machine field, so that the machine components of the machining associated control components form a common control group.

The machine installation according to the invention is characterized by a low wiring outlay in order to be able to control the production process or the treatment process of synthetic threads. The engine components associated with the engine components only require a power supply that can be provided by internal or external power sources. The invention is therefore particularly suitable for such machinery in which the machine components have their own Steuerintelligencez by the control components.

The invention will be described in more detail below with reference to some embodiments of machinery for the production and treatment of synthetic threads with reference to the accompanying drawings.

1 and 2, a first embodiment of a machine according to the invention for the production of synthetic threads is shown in several views. In Fig. 1 is an overall view schematically and in Fig. 2 is a partial view of the machinery shown schematically. Insofar as no explicit reference is made to one of the figures, the following description applies to both figures.

The machinery has a variety of machine components to control the manufacturing process for melt spinning synthetic filaments. A first machine component 1.1 is formed by an extruder 11, which is connected via a melt line system 12 with a plurality of spinning positions 20.

The spinning positions 20 are identically constructed and shown schematically in FIG. Within the spinning position 20 several machine components 1.2, 1.3, 1.4, 1.5 and 1.6 are provided to control the spinning of a group of threads within the spinning position 20. In that regard, a yarn sheet of, for example, 12, 16 or 32 threads is produced in each spinning position shown in FIG. The yarn sheet is indicated by the reference numeral 32 in FIG.

As machine components, the machine parts are referred to in this embodiment, which by drives and actuators significantly on Process are involved. Thus, the spinning position 20 as the first machine component 1.2 on a spinning pump device 13, which is connected to the melt line system 12 and which cooperates with a spinneret 14 for extruding the threads. A second machine component 1.3 is formed by a blower unit 16, which controls a cooling air supply of a cooling device 15. The cooling device 15 is arranged below the spinneret 14.

A next process step is carried out by the machine component 1.4, which comprises a wetting device 17. The guiding of the yarn sheet 32 for stripping and stretching of the threads Ver is performed by the machine component 1.5, which has a godet unit 18. At the end of the manufacturing process, the threads are wound into coils. For this purpose, the machine component 1.6 is provided, which forms the winding machine 19.

The machine components 1.2 to 1.6 provided within the spinning position form a machine field 3.1. Within the machine field 3.1, each machine component 1.2 to 1.6 has a control component assigned to it. Thus, the machine component 1.2 and the control component 2.2 form a unit. Accordingly, the machine components 1.3 to 1.6 are connected to the associated control components 2.3 to 2.6. For communication and data transmission, the control components 2.2 to 2.6 are wirelessly coupled to each other via a machine radio network 4. The machine radio network 4 is designed according to a WLAN standard, wherein the control component 2.2 is associated with a base station 5 with a router 6. The router 6 establishes the connections to the neighboring control components 2.3 to 2.6. For this purpose, the control components 2.3 to 2.6 each have a network card 7 on. In addition, the control components 2.3 to 2.6 component addresses are assigned to obtain a unique identification of the respective machine component within the network network. For example, the component address can be formed by a coded plug connection 34 between the control component 2.6 and the machine component 1.6, as shown in FIG.

As shown in FIG. 1, the machine system comprises several machine fingers, only four of the machine fields being shown here. The adjacent to the machine field 3.1 machine fields 3.2, 3.3 and 3.4 are constructed identically and each have a plurality of machine components. Here, the base stations 5 of the machine fields 3.1, 3.2, 3.3 and 3.4 a common local machine radio network 4. For central monitoring and operation of the machinery a central control station 8 is provided, the wireless in the machine radio network 4 of the control components 1.2 to 1.6 of the machine 3.1 to 3.4 is involved. Likewise, a control component 2.1 of the extruder 11 is integrated into the machine radio network 4 and coupled to the central operating station 8. The operating station 8 also has an Internet interface 9 in order to be able to communicate with a service station not shown here.

In the exemplary embodiment of the machine installation according to the invention shown in FIG. 1, in particular the machine components 1.6 are exchanged regularly for maintenance purposes in the machine fields 3.1 to 3.4. For this purpose, it is provided that the control components 2.6 of the machine components 1.6 within the machine installation are used as a control unit. Group 10.1 are summarized. The control group 10.1 is assigned a group address, so that, for example, via the operating station a parameter change for winding the threads directly each of the control components 2.6 of the machine fields 3.1 to 3.4 can be supplied. Furthermore, it is common for such winding machines 19 to include winding programs and control algorithms. A software update can therefore be fed directly via the control station 8 and the machine radio network 4 of the control components 2.6 combined within the control group 10.1.

The local machine radio network 4 of the machine shown in Fig. 1 can be tuned in terms of frequency and data transmission to the specific needs of the manufacturing process. Likewise, further network-capable terminals can be integrated into the local machine radio network. In particular, to support the monitoring and operation so trays or smartphones can integrate.

In Fig. 3 and 4, another embodiment of a machine system for the treatment of threads is shown in several views. The exemplary embodiment relates to a texturing machine, which is shown in a cross-sectional view in FIG. 3 and in a plan view in FIG. 4. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The machine systems provided for texturing threads comprise a multiplicity of processing positions per thread, with hundreds of threads being treated simultaneously within the machine installation. Thieves- Processing stations are identically designed within the machine system and each have several machine components for controlling the treatment process. FIG. 3 shows the machine components 1.1 to 1.8 of one of the processing stations. In this exemplary embodiment, the machine components 1.1 to 1.8 are formed by a first delivery mechanism 21, a heating device 22, a texturing device 25, a second delivery mechanism 26, an afterheating device 27, a third delivery mechanism 28, a winding device 29 and a traversing device 30. The machine components 1.1 to 1.8 are arranged within a machine frame 24 to a yarn path in succession to perform a texturing process. For this purpose, a thread 32 is held by a supply spool 22 in a gate frame 21. The thread 32 is withdrawn from the delivery mechanism 21 and heated by the heating device 22 within a texturing zone and subsequently cooled in a cooling device 23. Subsequently, the texturing device 25 and the second delivery mechanism 26 follow, wherein the thread 32 is stretched in the texturing zone. After an aftertreatment in the afterheating device 27, the thread is guided by the third delivery mechanism 28 to the winding device 29 and wound into a coil 33. Since the winding device 29 requires a larger machine width in relation to the upstream machine components 1.1 to 1.6, a plurality of winding devices 29 are arranged in the form of a tier in the machine frame 24.

The machine components 1.1 to 1.8 provided in the processing station are each assigned separate control components 2.1 to 2.8 in order to control the respective machine components 1.1 to 1.8. The control components 2.1 to 2.8 are connected as a control group via a wireless machine radio network 4 to a field control component 31.1. The machine components 1.1 to 1.8 of the processing station in this example form a control group.

As can be seen from the representation in FIG. 4, the field control component 31.1 is assigned further control components of adjacent processing stations. Thus, the machine components 1.1 to 1.8 of a total of twelve processing stations are combined to form a machine field 3.1. The provided within the machine field 3.1 control components 2.1 to 2.8 of the machine components 1.1 to 1.8 are all incorporated in the machine radio network 4 factory and connected to the field control component 31.1. In this exemplary embodiment, too, the machine radio network is designed according to a WLAN standard, with an operating station 8 having a base station 5 of the machine radio network 4. The base station 5 has a router 6 through which the connections to the field control components 31.1 and the control components of the machine components arranged in the machine field 3.1 are coordinated.

Basically, however, there is also the possibility that within the machine field 3.1, the machine components of the same kind are combined to form a control group. Thus, for example, the control components 1.7 of the traversing device 30 can advantageously be controlled as a control group within the machine field 3.1. As is apparent from Fig. 4, a plurality of field control components are provided in the machinery to control the plurality of processing stations. In this embodiment, the first two field control components 31.1 and 31.2 are shown. Each of the field control compo- Nenten 31.1 and 31.2 is integrated in the local machine radio network 4 and connected to the base station 5 at the central control station 8. Via the central operating station 8, an operator can monitor and control the texturing process of the entire machine installation. For transmission of data and information, the operator station 8 has an Internet interface 9.

To form and secure the connections in the machine radio network 4, there is also the possibility that the base station of the machine radio network is assigned to the field control components. For example, the field control components could be equal. The coordination for the data transfer between the control components and the field control components is coordinated in the example shown by the base station 5 of the control station 8.
