Abstract

The invention relates to a textile machine with a plurality of processing stations (1.1, 1.2, 1.3) each drawing off and treating one yarn from a feed spool (4.1-4.6). The feed spools (4.1-4.6) are held in a plurality of feed stations (3.1-3.6), which are arranged in tiers within a creel rack (2.2). Each of the feed spools (4.1-4.6) has a machine-readable label. According to the invention, in order to be able to access the product data for the feed spools (4.1-4.6) when processing the yarns in the processing stations (1.1, 1.2, 1.3), the label on the feed spools takes the form of an RFID tag (5.1-5.6), wherein at least one RFID antenna (6.1-6.6) connected to a read unit (7) is allocated to the feed stations (3.1-3.6) for each tier.

Description

Textile machine

The invention relates to a textile machine according to the preamble of the claim

1

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, from WO 2016/120187 A1 a textile machine for texturing a synthetic thread is known, which is previously produced in a melt spinning process and wound into a bobbin. The coils have a machine-readable identification that is read in when a gate frame of the textile machine is loaded and fed to a machine control for process control. Here, the gate frame has a gate address that is also stored in the machine control device and a link with the data of the original bobbins made light. Such gate racks, however, have a plurality of template positions in order to enable a continuous withdrawal of a thread within a processing point of the textile machine. Therefore, a direct link between the identification of the supply reel and the respective template is desired.

From EP 0 459 668 A1 a textile machine is known in which a machine-readable code on the supply reel or at the presentation point is detected directly when loading the supply reels with a scanner. This enables a link between the identification of the supply reel and the supply point. The reading of the identification on the supply reel by a scanner, however, requires a great deal of time and can also preferably only be carried out manually. In addition, the signals between the scanner and a receiving station are transmitted wirelessly, Such wireless transmission of signals is particularly susceptible to interference and can only be used to a limited extent in the vicinity of textile machines.

It is now the object of the invention to develop a textile machine of the generic type in such a way that as many data records as possible from supply bobbins can be assigned to the respective processing point of the textile machine.

A further aim of the invention is to provide a generic textile machine in which the feed points in a gate frame can be loaded manually or automatically with high flexibility, with the feed bobbins remaining identifiable for each processing point.

According to the invention, this object is achieved in that the identification of the supply bobbins is formed by an RFID label which is assigned to the supply locations per floor at least one RFID antenna and that the RFID antenna is connected to a reading unit.

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

The invention has the particular advantage that the respective identification of the supply spools can be detected electronically by a fixed RFID antenna and can be forwarded. For this purpose, the RFID antenna is assigned to one or more presentation points within a floor of the gate frame. This allows the relevant RFID label to be read out automatically after a supply reel has been loaded. The supply of the Vorla coil can be done manually or automatically by an automatic operator.

In order to avoid overlaps and incorrect readings in the multitude of tiered submission points, the development of the invention is preferably carried out in which the RFID antennas are designed so that only one code of the RFID label of the submission reel within the respective tier of the Gatters is detectable. The range of the RFID antennas for reading out the RFID labels is therefore limited to one floor.

Here, the development of the invention has proven particularly useful, in which the number of RFID antennas is equal to a number of presentation points in the gate frame. Thus, each of the presentation points has its own stationary RFID antenna, the readability of which is limited to the presentation point.

Elm to decrypt the code transmitted by the RFID antennas and assign it to the submission points, the development of the invention is provided in which the RFID antennas each have a stored address identifier in the reading unit, which is assigned to a position number of the submission point. This ensures that the codes of the supply spools transmitted to the reading unit remain assigned to the relevant supply locations.

The development of the invention, in which the processing points and the submission points cooperate via a fixed assignment, also ensures that the processing point can be identified by the position number of the submission points and thus can be combined with the supply reel and its code.

In order to ensure reliable signal transfer within the textile machine, the RFID antennas are each connected to the reading unit by a coaxial cable.

Due to the large number of RFID antennas that can be linked to the reading unit, the data read in by the reading unit is fed to a central machine control unit via an Ethernet cable. In this respect, data transfer with a high data density is possible.

Since the supply bobbins are preferably wound on bobbin tubes, the development of the invention is particularly advantageous in which the RFID labels are each glued to a surface of a bobbin of the supply bobbins. In this way, Use ge spool tubes and RFID tags multiple times to identify the spool wound on a spool tube via an individual code.

For this purpose, the identification of one of the RFID labels can preferably be formed by a serial number. The serial number is used to identify a data record that describes the thread wound in the supply package.

In order to be able to take into account the data assigned to the thread when treating the thread, the further development of the invention is particularly advantageous in which the machine control unit has at least one product database and product data software through which stored product data can be combined with the code of the original spool. This ensures that the data encoded using the encrypted codes of the supply bobbins are available to the processing station for further processing of the thread.

The invention is explained in more detail below using some exemplary embodiments of the textile machine according to the invention with reference to the accompanying figures.

They represent:

Fig. 1 is a schematic view of a first embodiment of the erfindungsge MAESSEN textile machine

FIG. 2 shows a schematic view of the gate frame of the textile machine according to FIG. 1. FIG. 3 shows a schematic plan view of the gate frame of the exemplary embodiment from FIG. 1

Fig. 4 is a schematic side view of a further embodiment of the inventive textile machine

In Fig. 1 is a schematic view of a first embodiment of the inventive textile machine is shown. The textile machine is shown by way of example as a texturing machine which has a plurality of processing points for treating, in particular texturing and drawing, a plurality of threads with several processing units. The embodiment of the textile machine according to FIG. 1 has a process frame 2.1 and a gate frame 2.2. The gate frame 2.2 and the process frame 2.1 are connected to one another via a thread feed device 9. The thread feed device 9 has a plurality of tubes 9.1 which are assigned with one end to the gate frame 2.2 and with an opposite end to a first delivery mechanism 11 on the process frame 2.1. Several processing points are arranged in the process frame 2.1, the representation in FIG. 1 showing the thread path at the processing point 1.1. The process aggregates provided for treating a thread 10 are explained below with reference to the thread path in the processing point 1.1.

A first delivery mechanism 11, a heating device 12, a cooling device 13, a friction unit 14, a second delivery mechanism 15, a set heating device 16, a third delivery mechanism 18 and a winding device 17.1 are provided for guiding and treating the thread in the processing point 1.1. The winding device 17.1 has a width which comprises a plurality of processing points within the process frame 2.1. Therefore, the winding devices of adjacent processing stations are arranged in layers one above the other. In this embodiment, the winding devices 17.2 and 17.3 are thus arranged above the winding device 17.1.

The process units 11, 12, 13, 14, 15,

16, 18 and 17.1 are well known and are explained in more detail, for example, in EP 2 145 848 B1. In this respect, reference is made at this point to the cited publication and no further explanation is given otherwise.

In the gate frame 2.2 a plurality of template locations for receiving template bobbins are arranged, which hold the threads for treatment and texturing. To explain the gate frame 2.2, reference is made in addition to FIG. 2, in which the gate frame is shown in an enlarged view. In this respect, the following description applies to both figures.

In the gate frame 2.2, a total of six presentation points 3.1 to 3.6 are ausgebil det. A supply reel 4.1 to 4.6 is held in each of the supply locations 3.1 to 3.6. For this purpose, each of the presentation points 3.1 to 3.6 each has a spool mandrel 24. The supply bobbins 4.1 to 4.6 are each wound on a winding tube 25, which are placed on the bobbin mandrels 24 of the supply points 3.1 to 3.6. On the circumference of the bobbin tubes 25, each of the supply bobbins 4.1 to 4.6 has an RFID label 5.1 to 5.6. The RFID labels 5.1 to 5.6 each have an individual code for identifying the supply reel. Here, each template coil 4.1 to 4.6 can be assigned a corresponding data record of the wound thread via the encryption of the code.

The submission steles 3.1 to 3.6 are arranged one above the other in levels, with the submission points held within a floor each being one of the processing points

1.1 to 1.3 are assigned. The presentation points 3.1 and 3.2 on the upper level of the gate frame 2.2 are assigned to the processing point 1.1. The ones at the submission points

3.1 and 3.2 held supply spools 4.1 and 4.2 are alternately withdrawn by the first delivery mechanism 11 of the processing point 1.1. For this purpose, the thread ends of the supply bobbins 4.1 and 4.2 are knotted together so that a continuous thread run within the processing point 1.1 is possible. A head thread guide 22.1 is assigned to the feed points 3.1 and 3.2 to withdraw the thread. Each tier within the gate frame 2.2 has a separate head thread guide 22.1, 22.2 and 22.3 in order to pull the threads off the supply bobbins. When one of the supply spools 4.1 or 4.2 is unwound, a new supply spool is attached to the relevant template 3.1 and 3.2 and knotted with the existing one. In this respect, a continuous process is guaranteed.

One RFID antenna 6.1 to 6.6 is assigned to each of the presentation points 3.1 to 3.6 on the gate frame 2.2. The RFID antennas are attached to the gate and their range for reading out the RFID labels 5.1 to 5.6 is restricted to the respective submission point 3.1 to 3.6. In this respect, the RFID antenna 6.1 is designed to detect the RFID label 5.1 on the supply reel 4.1.

The RFID antennas 6.1 to 6.6 are each connected to a reading unit 7 via a coaxial cable 8. Within the reading unit 7, each of the RFID antennas 6.1 to 6.6 can be identified by an address identifier and linked to a position number of the respective submission point. The reading unit 7 is via an Ethernet cable 21 connected to a central machine control unit 19. The machine control unit 19 is coupled to the drives and actuators of the processing stations 1.1 to 1.3 (not shown here).

In the exemplary embodiment shown in FIG. 1, the association between the presentation points 3.1 to 3.6 and the processing points 1.1 to 1.3 is ensured by the thread feed device 9.

FIG. 3 shows a top view of the creel frame 2.2 and the thread feed device 9 of the exemplary embodiment according to FIG. 1. The thread feed device 9 has a plurality of tubes 9.1, each of which guides a thread. The tube 9.1 is held at one end on a connection plate 23 which is arranged above the gate frame 2.2. The opposite free end of the tube 9.1 is assigned to the delivery unit 11 of the processing point 1.1 on the process frame 2.1. In the gate frame 2.2, the presentation point 3.1 and 3.2 is assigned to the tube 9.1. The position number of the submission points 3.1 and 3.2 are therefore always assigned to the processing point 1.1. Accordingly, the tubes 9.2 and 9.3 lead the threads from the pre-position sites 3.3 and 3.4 and 3.5 and 3.6 to the adjacent processing points 1.2 and 1.3. This ensures a fixed assignment between the processing points 1.1 to 1.3 and the presentation points 3.1 to 3.6 in the gate frame.

As can be seen from the illustration in FIG. 1, the reading unit 7 is connected to the machine control unit 19. The machine control unit 19 contains product data software that combines the identification of the supply bobbins 4.1 to 4.6 with process data and product data of the threads wound in the bobbins. The data sets for the supply bobbins or for the threads are stored in a product database 20. The product database 20 is designed as a cloud and is connected to the machine control unit 19. In this respect, the data records of the previous coils can be assigned to an end coil at the end of the treatment.

In the exemplary embodiment shown in FIG. 1, an RFID antenna is assigned to each presentation point to detect the codes of the presentation reels. In principle, however, there is also the possibility that the templates formed within a floor frames 3.1 and 3.2, 3.3 and 3.4 as well as 3.5 and 3.6 are each assigned to only one RFID antenna. Thus, both RFID labels 5.1 and 5.2 of the supply reels 4.1 and 4.2 can be detected jointly by an RFID antenna assigned to the floor and correspondingly forwarded to the reading unit 7.

In the exemplary embodiment of the textile machine shown in FIG. 1, the gate frame 2.2 is held stationary, so that the supply bobbins are fed to the template locations 3.1 to 3.6. In principle, however, there is also the possibility that the gate frames are designed to be movable and are held exchangeably within the textile machine. In order to enable automated detection of the RFID labels of the supply bobbins in mobile gate racks of this type, FIG. 4 shows a further exemplary embodiment of a possible arrangement within a textile machine. In the side view shown in Fig. 4, only the gate frame of several Bear processing sites of a textile machine is shown.

In Fig. 4 two juxtaposed gate frames 2.2 and 2.2 ‘are shown. Each of the gate racks has a plurality of tiered templates on top of one another 3.1 to 3.6. A feed coil 4.1 to 4.6 is held in each of the feed points 3.1 to 3.6. The supply spools 4.1 to 4.6 are each marked with an RFID label, which contains a code, in accordance with the aforementioned exemplary embodiment.

Between the two gate frames 2.2 and 2.2 ', which are designed to be movable, a carrier 26 is arranged which has separate RFID antennas 6.1 to 6.3 on several floors. The RFID antennas 6.1 to 6.3 are connected to the reading unit 7.

In this exemplary embodiment, the RFID antennas 6.1 to 6.3 are designed in such a way that the supply reels held within a floor in the gate frames 2.2 and 2.2 'can be detected with their RFID labels. In this case, the carrier 26 is held in place so that when one of the gate frames 2.2 is replaced, the relevant RFID labels can be read out on each of the newly fed supply reels. In the view shown in Fig. 4, only two adjacent gate racks egg ner textile machine are shown. Textile machines of this type usually have a large number of processing stations, the supply reels of which are held by a large number of gate frames. Depending on the design of the gate frames, several RFTD antennas held on the carrier or several directly integrated RFID antennas can be used in order to be able to carry out an automated coil detection of the supply coils. Here, the textile machine according to the invention is independent of whether the supply bobbins are automatically fed into the supply points or whether the supply bobbins are introduced into the gate row by manual loading.
