Abstract

The invention relates to a method and a device for producing a composite thread (13) from several individual threads (5.1, 5.2). The individual threads (5.1, 5.2) are held as supply spools (2.1, 2.2) in several supply stations (1.1, 1.2), pulled out in parallel, and combined to form the composite thread (13). The composite thread (13) is wound in a winding station (9) to produce an end spool (10). In order to make allocation and product tracking possible with a large number of supply stations, each of the supply spools (2.1, 2.2) features a separate RFID tag (4.1, 4.2) having an individual identification. The end spool (10) also has a separate RFID tag (4.3) having an individual identification, wherein the identifications of the supply spools (2.1, 2.2) are combined with the identification of the end spool (10) using a process control system (11).

Description

Method and device for producing a composite thread

The invention relates to a method for producing a composite thread from several individual threads according to the preamble of claim 1 and to a device for producing a composite thread from several individual threads according to the preamble of claim 7.

In the production and processing of threads, it is common practice that the threads are wound into bobbins for intermediate storage. Such bobbins contain an amount of thread that has its own process and product history due to its manufacture or processing. This history of the thread is usually monitored by recording process and product parameters and saved as a data record. This data set, which determines the thread wound in the bobbin, is assigned to the bobbin. This makes it possible to take this data into account in a subsequent process for further processing of the thread.

For example, WO 2016/120187 A1 discloses a method for producing a thread in which a synthetic thread is wound into a bobbin in a first process step and in which the thread is further processed in a subsequent process. The coil is marked with a code that contains an encrypted data record. During the further processing of the thread, the product parameters assigned to the thread can thus be recorded and assigned to the respective data record of the bobbin.

In the prior art, however, it is now also common for several threads to be combined in a subsequent process to form a composite thread which is wound as a bobbin for intermediate storage. Such a generic method and such a gat device device for producing a composite thread is known, for example, from EP 1 422 179 A2. In a known method and in the known device, several supply bobbins are held in several supply points, each of which has a single thread Weil. The individual threads are pulled off the supply spools and combined to form a composite thread. In this respect, there are a number of data records of the wound supply coils available, whose use for the following process requires a considerable amount of logistics. It should also be taken into account here that, in the event that the amount of thread in the supply package is insufficient to obtain a subsequent package after processing, an amount of thread from another supply package usually follows immediately. In this respect, the term composite thread is also used in this application for threads that are produced by several individual threads knotted at their ends.

It is now the object of the invention to improve a method and a device for the manufacture of a composite thread of the generic type in such a way that as possible all data records of a supply package can be assigned to the respective end product.

This object is achieved for a method according to the invention in that each of the supply spools has a separate RFID label with an individual identifier, that the end spool has a separate RFID label with an individual identifier and that the identification of the supply spools is provided by a process control system with the identifier the end coil.

The solution for the device according to the invention results from the fact that each of the supply spools has an RFID label with an individual identifier, the end spool has an RFID label with an individual identifier and that the individual identifiers of the spools can be read electronically and independently of one another can be transferred to a process control system.

Advantageous developments of the invention are defined by the features and combinations of features of the respective subclaims.

The invention is independent of whether the composite thread is formed from several individual threads withdrawn from supply bobbins at the same time or from several individual threads withdrawn one behind the other. Each individual thread can be identified by the individual identification of the feed bobbin. In addition, there is the possibility that the identification of the supply bobbin has already been used in the production of the single thread in order to store an assigned data record in a database, which at any time can be called up via the individual identifier. With the help of the individual identification of the end spool, the identification of the supply spool can be combined with the identification of the end spool by a process control system. The respective data records on product parameters and process parameters of the individual threads or the composite thread are initially not taken into account, but can be called up at any time from a product database using the individual identifiers.

In order to transmit the individual identifiers of the template spools to the process control system, these are preferably recorded electronically when the template locations are loaded. In the case of manual operation, a manual scanner is preferably used. As an alternative, however, there is also the possibility of equipping the template with an operating machine that enables electronic detection of the identifiers with an RFID antenna.

In order to obtain, in particular, a defined association between the presentation points and the winding point, the method variant is preferably implemented in which the presentation points are identified by an individual point address that is assigned to the winding point and is stored in the process control system. An association between the identification of the original spool and the location address of the original is possible so that, for example, the insertion of the original can take place without a predefined sequence. Because of the large number of presentation points, a high degree of flexibility is achieved when equipping the presentation points.

In order to be able to assign the product and process parameters of the composite thread as a data record to an end bobbin, the method variant is particularly advantageous in which the individual identifier of the end bobbin is electronically recorded when the winding point is loaded with a bobbin. In this case, detection is possible with manual operation by a scanner or with automated operation by an automatic operator with an RFID antenna, in order to pass on the identification of the end coil to the process control system.

The assignment can also be improved in that the winding point is identified by an individual winding address that is stored in the process control system. tem is deposited. Thus, by combining the location addresses of the presentation locations with the winding addresses of the winding locations, a fixed assignment is ensured even with a large number of winding locations.

The inventive device for producing a composite thread is suitable net to combine a plurality of individual threads to form a composite thread without loss of information. In this way, a plurality of identifiers of the supply spools can be combined in a simple manner with the individual identification of an end spool without taking stored data records into account. The electronic recognition of the RFID labels enables fast and precise recording and determination of a process control system.

The electronic detection is preferably carried out by the further development of the device according to the invention, in which a manual scanner or an automatic operating machine with at least one RFID antenna is provided. For example, the manual scanner can be used by an operator when loading the presentation points or when loading the winding point. In automated systems, electronic detection is preferably carried out by the RFID antenna that is assigned to the operating machine. This ensures that the individual IDs can be recorded quickly and reliably.

In order to obtain a defined association between the template and the winding points within the device, provision is also made for the template to each have a point address that is stored in the process control system.

In addition, in the case of a large number of winding points, each winding point can be assigned a winding address that is assigned to the relevant point addresses in the process control system.

Since the supply bobbins and the end bobbins are preferably wound on bobbin tubes, the further development of the device according to the invention is particularly advantageous in which the RFID labels are each attached to a surface of a winding tube of the template coils and / or are glued to a surface of a winding tube of the end coil. Such bobbin tubes and RFID labels can be used multiple times in order to identify the coil wound on the bobbin tube by means of an individual identifier.

The individual identification of one of the RFID labels is preferably formed by a serial number.

In order to obtain a link between the product data and the composite thread at the end of a process, the further development of the invention is preferably implemented in which the process control system has at least one product database and product data software, through which product data and individual identifiers of the master reels and end reels can be combined .

The method according to the invention for producing a composite thread is tert erläu in more detail below with reference to some exemplary embodiments of the device according to the invention for producing a composite thread with reference to the accompanying figures.

They represent:

Fig. 1 schematically shows a first embodiment of the device according to the invention Vorrich for producing a composite thread

Fig. 2 schematically shows a further embodiment of the device according to the invention Vorrich for producing a composite thread

In Fig. 1, a first embodiment of the device according to the invention for producing a composite thread from several individual threads is shown schematically. Only the devices essential to the invention are shown here.

The exemplary embodiment has two feed points 1.1 and 1.2, on which two feed bobbins 2.1 and 2.2 are held. Each of the supply bobbins 2.1 and 2.2 each carries a single thread 5.1 and 5.2. The number of submission points 1.1 and 1.2 is exemplary here. In principle, it is also possible to use a plurality of feed locations, which are usually arranged in a gate, for receiving feed bobbins.

In the exemplary embodiment shown in FIG. 1, a take-off device 7 is assigned to the presentation points 1.1 and 1.2. The take-off device 7 has several delivery mechanisms 7.1, 7.2 and 7.3. The delivery plant 7.1 is assigned to the submission point 1.1 for the deduction of the single thread 5.1. The delivery plant 7.2 is assigned to the presentation point 1.2 for withdrawing the single thread 5.2. The delivery system 7.3 is a Verbundeinrich device 8 downstream, which is provided for receiving and connecting the individual threads 5.1 and 5.2. The composite device 8 is shown only symbolically and could, for example, contain a twisting device, a twisting device, a texturing device or a swirling device or combinations of such devices. What is essential here is that the individual threads 5.1 and 5.2 are drawn off parallel to one another at the same time from the supply bobbins 2.1 and 2.2 and joined together to form a composite which is wound as a composite thread 13 in a winding device 9 to form an end bobbin 10. The winding device 9 is arranged after the delivery mechanism 7.3 and comprises a traversing device 9.3 and a bobbin holder 9.2. A winding tube 3.3 is held on the bobbin holder 9.2, on the circumference of which the composite thread 13 is wound to form the end bobbin 10.

Each of the supply bobbin 2.1 and 2.2 is also kept on a bobbin 3.1 and 3.2 ge. The winding tubes 3.1 and 3.2 are each attached to a mandrel in the presentation points 1.1 and 1.2. The length of the bobbin tubes 3.1 and 3.2 extends beyond the width of the original bobbins 2.1 and 2.2 and form free sleeve sections outside the original bobbins 2.1 and 2.2. An RFID label 4.1 and 4.2 is glued to each of these sleeve sections, winding sleeves 3.1 and 3.2. Each of the RFID labels 4.1 and 4.2 have an individual identifier, which is formed, for example, by a serial number.

The bobbin case 3.3 held on the bobbin holder 9.2 in the winding device 9 also has a sleeve section that remains free, an RFID label 4.3. The RFID label 4.3 contains an individual identifier that is assigned to the end coil 10. In the device shown in Fig. 1, only one winding point 9.1 is shown. Such devices usually have a plurality of winding points in order to wind a composite thread into an end bobbin at each of the winding points. The large number of take-off devices 7, compound devices 8 and winding devices 9 are controlled by a process control system. In Fig. 1, the process control system 11 is shown symbolically. The process control system 11 is connected to an operating unit 16.

In the device shown in Fig. 1, the loading of the feed points 1.1 and 1.2 with feed bobbins 2.1 and 2.2 and the loading of the winding point 9.1 with a bobbin 3.3 takes place manually by an operator. As shown in FIG. 1, the operator carries a manual scanner 12 in order to electronically record the individual identifiers of the RFID labels 4.1 and 4.2 of the supply reels 2.1 and 2.2 and to transmit them to the process control system 11 wirelessly. The wireless connection is symbolically represented here by a transmitter-receiver unit 20. Likewise, the identifier of the bobbin case 3.3 is scanned when the bobbin holder 9.2 is loaded on the RFID label 4.3 and is accordingly fed to the process control system 11.

The process control system 11 contains software for assigning the individual identifiers of the supply reels 2.1 and 2.2 to the identifier of the end reel 10.

In order to obtain a clear assignment within the device in the case of a large number of presentation points and winding points, it is alternatively provided that the pre-position points 1.1 and 1.2 each have a point address 14.1 and 14.2. The Stel lenadressen 14.1 and 14.2 are assigned to the winding station 9.1. There is the possibility that the winding point 9.1 also has a winding point address.

The station addresses 14.1 and 14.2 and their assignment to the winding station 9.1 are stored in the process control system 11. Alternatively, however, there is also the possibility that the operator reads in the respective location address 14.1 and 14.2 together with the identifiers of the supply reels 2.1 and 2.2 with the aid of the scanner 12 and transmits it to the process control system 11. The process control system 11 contains product data software which combines the identifiers of the supply bobbins 2.1 and 2.2 with process data and product data of the individual threads 5.1 and 5.2. The data sets for the individual threads 5.1 and 5.2 are stored in a product database 15. The product database 15 is designed as a cloud and is connected to the process control system 11. In this respect, the data records of the individual threads 5.1 and 5.2 at the end of the winding of the end spool 10 can be assigned to the composite thread 13 formed therefrom. In addition, the product and process parameters measured during the manufacture of the composite thread 13 can be recorded as a data record and can also be assigned to the end spool 10 via the identifier.

The method according to the invention and the device according to the invention thus have the particular advantage that each of the supply coils and each generated end coils each have an individual identifier and can be identified at any time. In addition, and if required, the respective data records can be called up using the identifier.

In the embodiment shown in FIG. 1, the composite thread is formed by simultaneous, parallel pulling off of several individual threads. In principle, however, there is also the possibility of forming a composite thread by individual threads that are knotted together. Such composite threads occur in particular when the thread length of the wound end spool is much longer than the thread length of an original spool. Thus the end spool in such a composite thread has a plurality of individual threads following one another. For this purpose, an embodiment of the device according to the invention is shown schematically in FIG. The exemplary embodiment has two feed points 1.1 and 1.2, each of which carries a feed reel 2.1 and 2.2. Each of the supply reels 2.1 and 2.2 is wound on a winding tube 3.1 and 3.2, which has a separate RFID label 4.1 and 4.2 on a freely projecting sleeve section. Each of the supply package 2.1 and 2.2 contains a single thread 5.1 and 5.2. The single thread 5.1 is knotted with one end to the single thread 5.2 of the supply package 2.2.

A withdrawal device 7 with a first delivery unit 7.1 and a second delivery unit 7.2 is assigned to the supply reels 2.1 and 2.2. The first delivery plant is 7.1 provided to pull the single thread 5.1 from the supply reel 2.1. The single thread 5.1 is guided through the thread guide 6.1. A treatment device 17 is arranged within a treatment path between the first delivery system 7.1 and the second delivery system 7.2. The treatment device 17 is shown symbolically and can, for example, be a texturing zone, a stretching zone, a swirling device or a combination of such units. Through the second delivery mechanism 7.2, the composite thread 13 is withdrawn from the treatment device and fed to the winding device 9. The winding device 9 is identical to the aforementioned exemplary embodiment according to FIG. 1, so that no further explanation is given at this point.

The devices of the embodiment shown in Fig. 2 show only one winding point 9.1. In principle, such devices are designed with a large number of winding points. The take-off devices 7, the treatment devices 17 and the winding device 9 are controlled by a process control system 11. The process control system 11 is identical in structure and function to the process control system 11 of the aforementioned exemplary embodiment according to FIG. 1, so that reference is also made to the aforementioned description at this point.

In contrast to the previous exemplary embodiment, the placement of the template 1.1 and 1.2 and the placement of the winding point 9.1 are automated. For example, the supply bobbins 2.1 and 2.2 can be carried out by a mobile operating machine 18. The automatic service machine 18 has an RFID antenna 19, which is designed to electronically record the identifiers of the supply reels 2.1 and 2.2 and to transmit the identifier to the process control system 11. Likewise, the identifier of the RFID label 4.3 on the bobbin 3 of the end coil 10 is read out via the RFID antenna 19 of the operating machine 18 and transmitted to the process control system 11. The exchange of the end spool 10 for a new spool tube 3.3 with a new RFID label 4.3 takes place automatically in the winding point 9.1. For example, the Aufspuleinrich device 9 could have a tube store, which has a plurality of spool tubes 3.3, each with RFID labels 4.3 glued on. About the bobbin holder 9.2, which is designed to be pivoted before given, the end spool 10 could be automati-based on a roll-off track after completion, to a new one with the bobbin holder 9.2 Take over winding tube from the tube storage. The recording and clearing of the end spool 10 could then be carried out by the automatic operator 18 or a separate dof device. In the embodiment shown in Fig. 2, the single thread is first

5.1 withdrawn from the supply reel 2.1 and wound as a composite thread 13 to the end reel 10 ge. After the thread piece of the single thread 5.1 that was wound on the supply bobbin 2.1 has been withdrawn, the single thread 5.2 is drawn from the supply bobbin 2.2 and fed as a composite thread 13 to the end bobbin 10. In this respect, the end spool 10 has two individual threads 5.1 and 5.2 fed one after the other. Within the process control system 11, the individual identifiers of the supply spools 2.1 and 2.2 are now combined with the identifier of the end spool 10, so that the assignment is guaranteed.

Here, too, there is the possibility of providing the presentation points 1.1 and 1.2 with point addresses in order to move between the winding point 9.1 and the presentation points 1.1 and

1.2 to get a clear assignment. In this respect, reference is made to the aforementioned description at this point.
