Description

The present invention comprises a method for melt-spinning and winding a plurality of yarns of the type according to the premise part of claim 1 and a method for melt-spinning and winding a plurality of yarns of the type according to the premise part of claim 7. With respect to the device for taking.

A large number of delicate filament strands are extruded from the polymer melt, bundled into a single yarn, processed and finally wound up to form a single package during the production of synthetic yarns, which are assigned to yarns as a measure of yarn quality. It is normal to detect the process or product parameters that are being used. Such quality data is especially important for subsequent processes in which the subsequent processing of the yarn is carried out.

From International Publication No. 2016/120187, a method of the form described at the beginning and a device of the form described at the beginning for melt-spinning and winding a plurality of yarns are known. Subsequent processes are directly assigned to these threads. In this case, the yarn manufacturing process data and product data are assigned directly to the wound package. The data in the package is either digitally assigned to a subsequent process or assigned directly to the package by an identifier. The package is correspondingly given an identification symbol prior to packaging, ensuring identification and data allocation in subsequent processes.

Known methods and devices for melt-spinning and winding multiple yarns finally assign the data obtained in online and offline operations to the package and carry out the corresponding identification symbols on the package. Therefore, it takes a lot of time and effort for logistics. For example, it is known to use a plurality of spinning positions in which one group of yarns, and thus a plurality of packages, are formed side by side in parallel to produce synthetic yarns. Therefore, it takes more time and effort to obtain the data in the offline method, and it is usual that the package manufactured in the online operation is first interim stored. In this case, it is useless to form the coding in the package instead of the data identification symbol just before the packaging. The risk of a package being associated with incorrect data in subsequent processes is extremely high.

In addition, it is also common practice to manually remove the finished package by an operator in the melt spinning process. To that extent, the automated order of package unloading from the melt spinning process to packaging is not guaranteed.

Therefore, the present invention has improved the method for melt-spinning and winding multiple yarns as well as the apparatus for melt-spinning and winding multiple yarns, and accurate allocation of data to the wound package is always possible. It has the task of ensuring that it is guaranteed.

Another object of the present invention is to allow each package to be assigned a larger number of applicable process and product parameters of wound yarn.

This task, according to the invention, is to code the packages, each forming one RFID label and / or writing on each one RFID label, and each package from a take-up spindle. It is solved by assigning an identification code immediately after the withdrawal.

For the device according to the invention, the winding device is assigned a coding device, which is connected to a package tracking system for RFID label formation and / or writing. Occurs.

The advantageous variants of the invention are defined by the features and combinations of features of each dependent claim.

The present invention has the special advantage that each package formed by the melt spinning process receives an identification code by a take-up device immediately after completion. The identification code is embedded in the RFID label to identify the package. Read at each point in time. This creates the possibility of assigning or associating yarns at the manufacturing site, spinning position and spinning position in one package. An identification code that allows different identification symbols to be assigned to packages formed at adjacent winding points is affixed to the package as an irreplaceable identification symbol. To that extent, the product and process parameters measured in the yarn wound during the melt spinning process are uniquely assigned to each package via an identification code. For coding, each RFID label can be formed directly, and an alternative is to write to an existing RFID label. Further, the RFID label has an advantage that additional data can be recorded on the RFID label in addition to the pure identification code.

In one advantageous variant of the method according to the invention, the RFID label is sequentially written with its respective identification code directly upon withdrawal of the package from the take-up spindle and the RFID label is held in the winding tube. Therefore, the winding tube may be configured with a passive RFID label suitable for recording data.

If the RFID label attached to the winding tube already has data on the winding tube cord or winding tube inspection, how to read the RFID label on the winding tube with an RFID scanner when the winding tube is attached to the winding spindle. Variations are particularly advantageous. This allows the winding cord or winding data to be taken into account when coding the package.

However, as an alternative, it is possible to implement a variation of the method in which an RFID label having each identification data is printed before the package is withdrawn, and the operator attaches the RFID label to the extracted package. Variations on this method are particularly advantageous for manual operation and removal of the package at the spinning position.

The identification code allows multiple data to be directly associated with the package. To that extent, variations in the way in which each identification code is assigned a dataset of process data, machine data and product data and the dataset is stored in data memory are preferably implemented. As a result, at each time point, the data set corresponding to the thread in the package can be called by the identification code. Alternatively, depending on the size of the dataset, the possibility of storing the dataset directly on the RFID label also arises.

Regardless of the subsequent process of whether the yarn undergoes refining, eg textile processing, or the yarn is fed directly to the textile mill, the package identification code is read during the subsequent process and the yarn continues. Assigned to processing.

To that extent, all machine data, process data and product data are provided to subsequent processes to take into account the corresponding measures during the subsequent processing of the yarn. One of the identification codes, a dataset of identification codes, may be assigned to the corresponding identification code by, for example, another data acquired during the package test in offline operation.

In order to allow the coding of the package to be performed immediately after winding, a variation of the device according to the invention, wherein the coding device has a label printing machine and / or an RFID scanner, is particularly advantageous. be. This causes the RFID label to be formed directly with the corresponding identification code in the take-up device. When using label presses, the possibility of assigning one separate label press to each winder, and alternatives to one group of winders with one of multiple label presses. Possibility of allocation arises.

For writing and reading RFID labels, RFID scanners are configured as writers / readers. A separate RFID scanner is assigned to each take-up device. Therefore, the package is automatically coded on each withdrawal from the take-up spindle.

After each package change in the take-up device, a package tracking system is connected to the machine control device for the transmission of data and control signals so that the corresponding identification code is present. A variant of the apparatus according to the invention, which has a coding module for generating an identification code, has been advantageously implemented. Therefore, there is a possibility that the package tracking device can obtain information on the imminent package exchange in a timely manner on the one hand, and can carry out the association with each data after the identification code is generated on the other hand.

The package tracking system has a data memory for accommodating and storing multiple data and identification codes. Based on the large amount of data, data memory is advantageously realized by cloud memory. This cloud memory has another free interface for exchanging data.

In order to incorporate the identification code directly onto the RFID label when the package is pulled out, a variation of the invention in which the winding tube held on the take-up spindle has one RFID label each writable and readable. Is advantageous.

In this case, the RFID scanner is located corresponding to the free end of the take-up spindle, and each take-up device supports a separate RFID scanner, thus automating the coding in a simple form. To that extent, full tracking of the package is possible.

Alternatively, an RFID label formed by a label printing press, each with one identification code, is manually assigned to the package drawn from the take-up spindle. This allows the RFID label to be attached directly to the package.

It is further specified that the package tracking system and / or data memory is connected to the process control device of the subsequent process so that the data allocated to the package can be used by the subsequent process. This allows all data important during yarn production to be assigned to subsequent processes via their respective identification codes.

Therefore, the present invention is particularly suitable for utilizing all the data detected during melt spinning of the yarn for the subsequent processing of the yarn. In this case, all melt spinning processes in which the formed yarns are wound to form a package are relevant to the present invention. Thus, for example, a POY, FDY, IDY, HOY, or BCF package can be coded in this way.

A method according to the present invention for melt-spinning and winding a plurality of yarns will be described in detail below with reference to the accompanying drawings for one embodiment of the apparatus according to the present invention.

It is a schematic front view of one Example of the apparatus which concerns on this invention which provided a plurality of spinning positions. It is a schematic side view of the Example shown in FIG. It is a schematic front view which shows the spinning position of one of the plurality of spinning positions of the Example shown in FIG. 1 immediately before the package exchange. FIG. 5 is a schematic side view of another embodiment of the apparatus according to the invention for melt spinning and winding yarn. FIG. 6 is a schematic front view of another embodiment of the apparatus according to the invention with a plurality of spinning positions.

1 and 2 show a front view and a side view of a first embodiment of an apparatus according to the present invention for melt-spinning and winding a plurality of yarns. The following description applies to both drawings unless explicitly associated with one of the drawings.

Examples of the apparatus according to the present invention have a plurality of spinning positions 1.1 to 1.7. These spinning positions 1.1 to 1.7 are arranged side by side in a row arrangement to form the machine longitudinal side. The number of spinning positions shown in FIG. 1 is merely exemplary. Basically, such a device includes multiple identical spinning positions.

The structures of spinning positions 1.1 to 1.7 shown in FIGS. 1 and 2 have the same structure. The configuration of the example of the spinning position 1.1 shown in the side view in FIG. 2 will be described in detail below.

Each spinning position 1.1 to 1.7 has a spinning device 2. The spinning device 2 includes a spinning beam 2.2. The spinning beam 2.2 supports a plurality of spinning nozzles 2.1 on the lower surface. The spinning nozzle 2.1 is connected to the spinning pump 2.3. The spinning pump 2.3 is preferably configured as a multi-pump, producing a separate melt stream for each spinning nozzle 2.1. The spinning pump 2.3 is connected to a melt source (not shown), such as an extruder, via a melt supply section 2.4. A cooling device 3 is arranged below the spinning device 2. The cooling device 3 is formed by the cooling shaft 3.1 in the blow chamber 3.3 in this embodiment. The cooling shaft 3.1 is followed by a descent shaft 3.2 in the thread running direction.

A collecting device 4 is arranged below the descent shaft 3.2. The collecting device 4 has a plurality of yarn guides 4.1 in order to bundle the filaments extruded for each spinning nozzle 2.1 into one yarn. In this embodiment, the spinning device 2 forms four yarns, which are indicated by reference numeral 8. The number of threads is exemplary. Such a spinning device 2 can simultaneously form up to 32 yarns at each spinning position.

An oil agent supply device 5 is arranged correspondingly to the collecting device 4. The thread 8 is wetted by the oil supply device 5. The yarn is drawn as a group of yarns by the Godette device 6 and supplied to the take-up device 7. In this embodiment, the godet device 6 is formed by two driven godets 6.1. An entanglement device 6.2 is arranged between the godets 6.1 in order to entangle the threads 8 separately.

The take-up device 7 has one take-up point 7.5 for each thread 8. A total of four take-up points 7.5 extend along the take-up spindle 7.1. The take-up spindle 7.1 is held so as to project in the take-up revolver 7.2. The take-up revolver 7.2 supports two take-up spindles 7.1. These take-up spindles 7.1 are alternately guided to a take-up area and an exchange area. On the peripheral surface of the take-up spindle 7.1, one winding tube 12 is tightly tightened at each winding point 7.5, whereby the thread is wound on the peripheral surface of the winding tube 12, and one package is provided for each. 13 can be formed.

At each winding point 7.5, one of the plurality of converting rollers 7.6 is correspondingly arranged for the distribution and separation of the yarn 8. The converting roller 7.6 is directly rearranged in the Godette device 6. In order to wind and lay the thread 8 to form the package 13, each winding point 7.5 has a twill swing device 7.3. The twill swing device 7.3 cooperates with the pressing roller 7.4. The pressing roller 7.4 is arranged parallel to the take-up spindle 7.1 and is placed on the surface of the package 13 when the yarn is taken up.

A plurality of drive devices 7.8 are arranged on the side of the machine frame 7.7 opposite to the take-up spindle 7.1. These drive devices 7.8 are arranged corresponding to the take-up spindle 7.1, take-up revolver 7.2, and twill swing device 7.3. The drive device 7.8 is connected to the machine control device 9.

The machine control device 9 is similarly connected to the Godette 6.1 of the Godette device 6 and the spinning pump 2.3 of the spinning device 2.

A package tracking system 10 is provided for coding the package 13 formed by the take-up device 7 immediately after manufacturing. The package tracking system 10 is connected to the machine control device 9 for the transmission of data and control signals. The package tracking system 10 has a coding module 10.1. The coding module 10.1 generates a separate identification code for each completed package at each spinning position 1.1-1.7. A coding module 10.1 is connected to the coding device 14 for transmitting the identification code. The coding device 14 is assigned to the take-up device 7. In this embodiment, the coding device 14 is configured by RFID scanner 14.2. The RFID scanner 14.2 is configured as a writer / reader, which can read data from the RFID label or write data to the RFID label. The RFID scanner 14.2 is located corresponding to the protruding end of the take-up spindle 7.1 and is held by the mechanical frame 7.7 just above the take-up spindle 7.1.

In particular, as is clear from the drawing of FIG. 2, each winding tube 12 has an RFID label 11. The RFID label 11 provided on the winding tube 12 is passively formed to be writable and readable. The RFID label 11 may be attached to the outside or inside of the tube surface of the winding tube 12. Basically, it is also possible to integrate the RFID label as a microchip on the peripheral surface of the winding tube 12.

The package tracking system 10 has a data memory 10.2. This data memory 10.2 has at least one separate interface 15 for connection to subsequent processes.

For further description of the package tracking system, FIG. 3 is also referenced below. In FIG. 3, the spinning position 1.1 of the embodiment shown in FIG. 1 is shown in the front view, and the take-up revolver 7.2 is operated to start the package change.

When the wound package 13 has a predetermined maximum package diameter or a predetermined package weight, package replacement is initiated in the winding device 7. The package tracking system 10 is signaled via the machine control device 9 that the package replacement is imminent in the winding device 7 at the spinning position 1.1. Now, the package tracking system 10 is activated and a total of four identification codes are generated via the coding module 10.1 for the take-up device 7 at spinning position 1.1, and these identification codes are generated at spinning position 1. It is transmitted to the RFID scanner 14.2 provided in the winding device 7 of 1. After the take-up spindle 7.1 with the fully formed package reaches its replacement position, the package 13 is sequentially withdrawn from the take-up spindle 7.1. At that time, an identification code transmitted to each RFID label 11 provided on the winding tube 12 of the wound package 13 is given via the REID scanner 14.2. Each RFID label 11 provided on the winding tube 12 of the wound package 13 is now given an individual identification code. This identification code is associated within the package tracking system 10 with product data, machine data and process data detected for the relevant yarn during the take-up period. The data set generated in this way is addressed via the identification code and stored in the data memory 10.2. To that extent, one data set is stored in the data memory 10.2 for each identification code, and this data set includes the yarn manufacturing history. The data set is called from the data memory 10.2 each time via the identification code, so that the process control of the subsequent process can consider the corresponding information. To that extent, the data memory 10.2 is preferably configured as a virtual memory and is connected to subsequent processes via a wireless connection.

However, there is a further possibility that the data additionally obtained in the melt spinning process obtained in the laboratory test will be added to the data set in the data memory 10.2 via the identification code. To that extent, the dataset can be replenished for each package 13 within the data memory 10.2.

However, basically, by having the RFID scanner 14.2 write data on the RFID label 11, there is a possibility that at least some data will be assigned directly to the package. To that extent, each RFID label may include, for example, additional product information for classification, in addition to the identification code.

As can be seen from the drawing of FIG. 1, each take-up device 7 at spinning positions 1.1 to 1.7 has one separate RFID scanner 14.2. Therefore, each package formed in the melt spinning process can be coded with a unique identification code.

The embodiments illustrated in FIGS. 1 and 2 of the apparatus of the present invention for melt spinning and winding yarn are particularly suitable for automation. In this case, all steps are carried out without operator intervention.

An alternative configuration of the device according to the invention is illustrated in FIG. 4 in case the wound package 13 must be manually removed from the take-up spindle 7.1. FIG. 4 schematically shows the spinning position 1.1 in a side view. Since the embodiment shown in FIG. 4 is substantially the same as the embodiment shown in FIG. 2, only the difference will be described below, and the above description will be referred to for other points.

In the embodiment illustrated in FIG. 4 of the apparatus according to the present invention for melt spinning and winding yarn, the coding apparatus 14 is formed by a label printing machine 14.1. The label printing machine 14.1 can be controlled by a coding module 10.1 as a package tracking system 10, which can form an RFID label 11 with an identification code. The RFID label 11 is taken out from the label printing machine 14.1 by the operator and directly supplied to the package 13. Therefore, the RFID label 11 is preferably attached to the peripheral surface of the package 13. The RFID label 11 is sequentially attached to each package 13 drawn from the take-up spindle 7.1. Each RFID label 11 contains an individual identification code.

The association between the data set regarding the yarn manufacturing history and the identification code is the same as in the above-described embodiment. Both the dataset and the identification code are stored in data memory 10.2.

In the embodiment shown in FIG. 4, each take-up device 7 at spinning positions 1.1 to 1.7 may each have one separate label printing press 14.1. However, preferably, one of the plurality of label printing presses 14.1 is assigned to one group of winding devices 7. Thus, for example, one common label printing machine 14.1 may be assigned to spinning positions 1.1 and 1.2. Based on manual operation, this configuration of the present invention is particularly suitable for partially automated equipment. In this case, the label printing machine 14.1 can print additional data or quality features on the RFID label 11. Thus, for example, the quality level of the package can be displayed directly.

The RFID label 11 affixed to the winding tube 12 of the package 13 or directly to the package 13 is maintained until the subsequent processing of the yarn and is used to read the identification code in each subsequent process. The read identification code allows all data related to the manufacture of the packaging yarn to be recalled and passed to subsequent processes.

FIG. 5 is a front view showing another embodiment of the apparatus according to the present invention for melt-spinning and winding a plurality of yarns. Since the embodiment shown in FIG. 5 is almost the same as the embodiment shown in FIG. 1, only the difference will be described below, and the above description will be referred to for other points.

In the embodiment shown in FIG. 5, the coding device 14 assigned to the take-up device 7 is configured by the RFID antenna 14.3. Each RFID antenna 14.3 assigned to spinning positions 1.1 to 1.7 of the take-up device 7 is configured the same and is configured as a reader / writer to read or write RFID labels. ing. The RFID antenna 14.3 is wirelessly connected to the package tracking system 10 as well as the coding module 10.1 via, for example, a wireless connection.

The function in the spinning positions 1.1 to 1.7 for coding the package formed in the take-up device 7 is the same as the above-described embodiment shown in FIGS. 1 and 2. Thus, for example, an RFID label that is already present in the winding tube is read when the winding tube is mounted on one of the winding spindles, and thereby the winding tube data or winding tube that is present in some cases. The code can be transmitted to the package tracking system 10. The association between the machine control device 9 and the package tracking system 10 assigns each winding tube to the yarn and thus to the spinning nozzle within each spinning position. Thereby, the process data and the product data obtained for each thread during the winding of the package can be passed to the package tracking system 10 via the machine control device 9. Within the coding module 10.1, a separate identification code is generated for each package formed and transmitted to RFID antenna 14.3. The RFID antenna 14.3 can then write the identification code on the corresponding RFID label upon withdrawal of the package. However, as an alternative, there is the possibility that the pre-loaded winding cord will continue to be used as the identification code, which will make the packaging data known in the subsequent machining process in addition to the winding data.

Therefore, the method according to the present invention for melt spinning and winding a plurality of yarns and the apparatus according to the present invention are particularly suitable for providing a manufacturing history of synthetic yarns in the form of data collection. Therefore, this digital information in the package of wound yarn is particularly suitable for correspondingly controlling subsequent processes. In addition, this data can be supplemented by other product and process data generated in subsequent machining. Therefore, the yarn history can be finally allocated to the final product.
