Description
Technical Field
The present invention relates to a melt spinning method for manufacturing synthetic staple fibers and a melt spinning apparatus for manufacturing synthetic staple fibers.
Background
Melt spinning processes and melt spinning apparatuses of this type for the production of synthetic staple fibers are disclosed, for example, by DE102017100592 A1.
In the manufacture of synthetic staple fibers, a plurality of fiber bundles are typically extruded from a polymer melt through a plurality of spinning devices. The fiber bundle is then processed in multiple steps to obtain the desired physical properties of the fiber bundle depending on the polymer type. The fiber bundles are then crimped and then cut to form staple fibers. The chopped fibers are pressed into bales at the end of the manufacturing process. Such staple fiber bales may then be transported and sent to further processing.
Depending on the equipment capacity, such staple fibers may be continuously pressed from the spinning device into bales or intermittently pressed from the pick-up fiber bundles into bales. Thus, the fibre bundle is first placed in an intermittent melt spinning apparatus in a can, for example from DE102017100592. The cans are then brought together in a creel in a plurality of rows so that all the fiber bundles are continuously drawn from the cans and then processed into staple fibers. In such complex melt spinning processes and melt spinning apparatuses, a large amount of data that can be assigned to the produced staple fibers is generated by monitoring process parameters and product parameters.
It is known in textile manufacturing that process and product data are stored on a microchip. Such microchip is assigned to a preliminary product or a final product and can be provided to a respective textile process as required. Such a system is for example from US9,811,804B1. The staple fibers are provided to other processing units, wherein each staple fiber bundle obtains an RFID chip containing all information about the product and the manufacturing process. This results in large amounts of data that must be maintained in machine-readable form. However, the underlying problem arises here that, when data records are read and written, they are transmitted contactlessly via a wireless network which is susceptible to interference. In addition, it must be considered that data reading and writing takes longer.
Disclosure of Invention
The object of the present invention is therefore to provide a melt-spinning method and a melt-spinning apparatus for the production of synthetic staple fibers of this type, in which a reliable correlation between product data and the produced staple fibers can be achieved.
According to the present invention, this task is accomplished for the melt spinning process by obtaining a separate machine readable identifier for each bale, and the identifier of the bale, the forming bale start time, and the forming bale end time are transmitted to the process control system.
For melt spinning apparatuses this task is accomplished in that an identification generator for providing a machine-readable identifier for each bale or a pallet for holding the bale and equipped with a machine-readable identifier is assigned to the bale press means.
The invention has the particular advantage that bales with short fibers are marked only by a separate identifier which is machine-readable and can be provided electronically to a process control system or other machine control unit. Because of the association of the bale forming start time and bale forming end time, the short fibers that are concentrated in the bale during bale forming can also be uniquely identified in its manufacture.
A further development of the method according to the invention is then preferably carried out in that a plurality of processes and/or product parameters obtained during the period between the start time and the end time of forming the package are collected into a product data record and the product data record is assigned to the identifier of the associated package. The product data records can then be assigned to the relevant short fibers by means of the identifier of the bundle as required. Thus, for example, a data printout may be generated by an identifier when the packages are stacked and attached to a delivery file. But the product data record may also be electronically acquired in a later process by means of the identifier of the package.
In order to be able to read the identifier of the bundle as automatically as possible, the following method variant is particularly advantageous, to which the encoded RFID tag is attached as an identifier. The code can then be automatically acquired contactlessly by means of electromagnetic waves via the corresponding receiving system to authenticate the package.
In order to distribute the baled staple fibers to the product data for further processing, the following method variants are preferably carried out, wherein the product data record is stored in a product database under the RFID tag code. Such a product database, which may be contained in the cloud, for example, is always accessible, so that the product data of the short fibers can be retrieved at any time by means of the code of the bundle.
In the case of a need to temporarily store the fiber bundles for performing an intermittent melt spinning process, a variant of this process is specified in which the fiber bundles are temporarily stored in cans after extrusion and each can is encoded by an RFID chip. By simply encoding the cans, they can be used multiple times to perform intermediate storage of the fiber bundles.
The specification and identification of the fiber bundle can be achieved by a variant of the method in which the encoding of the RFID chip of the can, the determination of at least one fiber parameter of the stored fiber bundle, is stored in the process control system.
This allows the barrel code to be read and transmitted to the process control system as the fiber bundle is drawn from the plurality of barrels. Thus, despite the temporary storage of the fiber bundles, there is no gap in the supply and distribution of process and product data.
The coded fibre parameters assigned to the cans are then jointly assigned to the product data record of the bundle, so that even in the case of the discontinuous melt spinning method all relevant process steps for the production of staple fibres are contained in the product data record. Thus, the association between the produced staple fibers and the extruded filaments is maintained, especially when using a plurality of spinning lines with a plurality of spinning devices operating in parallel.
A feature of the melt spinning process is that the individual machine readable identifiers required to authenticate the package are immediately made available by the identifier generator and can be added to the package. Alternatively, such an identifier may be attached directly to the pallet that is used to house the bundle. Because the bales or pallets are identified, the staple fibers contained therein can be identified.
In order to correlate the short fibers provided during the formation of the bale with the continuously obtained product and process parameters, the bale pressing means comprises a timer connected to the process control system, whereby the start time and the end time of the formation of the bale can be obtained. Product data and/or process data obtained during the time period in which the package is formed may then be correlated by authentication of the package.
In order to obtain the identifier as automatically and in a contactless manner as possible, a modification of the melt spinning apparatus is preferably realized in which the identifier is formed by an RFID tag, which is realized in the form of a code. Unique authentication of the package is ensured by the separate code of the RFID tag.
An RFID antenna coupled to the process control system is configured to transmit the code. This also allows pre-marked pallets to be used to house bales.
For an intermittent melt spinning apparatus, an improvement of the invention is provided wherein a plurality of cans are provided to house the fiber bundle, each can is equipped with an RFID chip, and the fiber placement device for filling the cans includes an RFID antenna connected to the process control system. The RFID chip may be fixedly attached to the rim such that the code it contains is repeatedly used to identify the fiber bundle contained in the can.
In order to be able to identify the fiber bundle when the cans are emptied, the creel for receiving the cans includes at least one further RFID antenna connected to the process control system.
The RFID antennas are each connected to a reading unit of the process control system via coaxial cables, so that an undisturbed transmission of the respective antenna signals to the process control system can be achieved. The code of the RFID chip and the code of the RFID tag may then be provided to the process control system.
In order to obtain a unique signal distribution in the presence of a plurality of RFID antennas, according to an advantageous development of the invention, each RFID antenna is identified by a location address stored in the process control system.
The code of the RFID tag and/or the code of the RFID chip is preferably formed by an individual serial number. This allows avoiding measures for generating codes or encodings.
In order to be able to take into account the product data assigned to the staple fibers when they are further processed, the following inventive development is particularly advantageous in that the process control system comprises at least one product database and product data software, whereby the stored product data can be combined with the bundle code. This ensures that the data encoded by the encrypted code of the bundle is available at the processing site during further processing of the fibre.
Drawings
The melt spinning method according to the present invention is explained in more detail below based on several embodiments of the melt spinning apparatus and with reference to the drawings, in which:
figure 1 schematically shows a continuous melt spinning apparatus for the manufacture of staple fibers,
fig. 2 schematically illustrates an intermittent melt spinning apparatus for staple fiber manufacture.
Detailed Description
A first embodiment of a melt spinning apparatus according to the present invention is schematically shown in fig. 1. The examples illustrate a continuous melt spinning process for staple fiber manufacture. This embodiment comprises a spinning device 1, which is equipped with a plurality of spinning nozzles 1.2 on a spinning beam 1.1. The spinning nozzles 1.2 are connected to a melt source, not shown here, and each extrude a plurality of filaments from the polymer melt, which are brought together to form a bundle of filaments 2. A plurality of coolant distribution heads 1.3 are distributed to the spinning device 1 for freshly extruded filaments under the spinning nozzle 1.2 Fang Lengque. It is also common to wet the filament bundles with processing aids.
The fiber bundle 2 produced by the spinning device 1 is then drawn off by the drawing unit 3 and drawn in the drawing units 4.1 and 4.2. A temperature and humidity adjusting device 5 is provided in the drawing units 4.1, 4.2 to perform the heat treatment of the fiber bundle 2. The temperature and humidity regulation of the fiber bundles can be carried out by means of a water bath or steam.
After drawing, the fiber bundles are brought together by the laying device 6 and fed to the crimping device 7. The fiber bundle is crimped by means of a crimping device 7 by a process called stuffer crimping, and then dried in a drying device 9. The drying device 9 is followed by a pulling device 8 to supply the fiber bundle 2 to a cutting device 10. The fiber bundle is cut into short fibers 27 in the cutting device 10. The short fibers 27 are pneumatically supplied to the bale pressing means 11 and they are pressed there into bales 12. The identification generator 14 is assigned to the bale press means 11 to generate a separate machine-readable identification for each generated bale 12. In this embodiment, the RFID tag 13 is provided as an identifier and attached to the bundle 12.
Further, an RFID antenna 15 is assigned to the bale press device 11 and is connected to the reading unit 18 by a coaxial cable 19. The reading unit 18 is assigned to the process control system 17.
The process control system 17 is connected to a timer 16 assigned to the bale press means 11.
In this embodiment, the formed bale 12 is held on a pallet 21.
The process control system 17 is coupled to a number of actuators and sensors to control and monitor numerous devices of the melt spinning apparatus. The process and product parameters obtained and transmitted are not described in more detail herein. In principle, polymer type, draw ratio, heating, fiber thickness, etc. may be obtained and provided to the process control system.
In the continuous melt spinning process as shown in fig. 1, fiber bundles are continuously produced from a polymer melt by a spinning apparatus 1. The fiber bundle 2 is drawn from the spinning device 1 by a drawing unit 3 and drawn in drawing units 4.1 and 4.2. The fiber bundle 2 is subjected to temperature and humidity control by a temperature and humidity control device 5, for example, by a water bath. Depending on the fibre type, the fibre bundle 2 can be further processed by means of a calendering device after it has been drawn.
In the process shown in fig. 1, the fiber bundles are brought together by the laying device 6 to the working width for the crimping device 7 and crimped by the crimping device 7. Next, the fiber bundle is cut by the cutting device 10 to form short fibers 27. The staple fibers 27 are then crimped into the bale 12. To this end, the start time for forming the bundle is obtained by means of a timer 16, which is transmitted to the process control system 17. Once the bale 12 is formed, the end time of forming the bale is provided to the process control system 17 by the timer 16. The process and/or product parameters obtained during the period between the start time and the end time of forming the package are combined in the process control system 17 to form a product data record. The RFID tag 13 is generated by an identification generator 14 and added to the package 12. The code contained in the RFID tag 13 is acquired through the RFID antenna 15 and supplied to the reading unit 18. The code of the package 12 is transmitted to the process control system 17, which correlates the relevant product data records to the code. The existing serial number of the RFID tag may be used as a code, for example. The product data record so encoded is then stored in the product database 20. The product database 20 may for example be formed for this purpose in the cloud.
Retrieval of the product data record may be accomplished at any time and any location by authentication of the package 12 and associated coding.
The product and process data collected during the time period that the package is formed is executed by product data software contained in the process control system 17. All process and product parameters monitored and obtained during the manufacturing process can then be assigned to the staple fibers. The production time of the fiber bundle before cutting is considered here.
Another embodiment of a melt spinning process according to the present invention is schematically shown in fig. 2. The embodiment according to fig. 2 shows an intermittent melt spinning method for short fiber production, in which the fiber bundles are laid into a can for temporary storage. The fiber placement device 22 is assigned to the spinning device 1 for this purpose. The spinning device 1 has the same structure as the embodiment according to fig. 1, and no further explanation is provided here. The fiber bundle 2 produced by the spinning device 1 is then drawn out by the drawing unit 3 and supplied to the fiber placement device 22. The fiber placement device 22 has a skein mechanism 22.1 for feeding the fiber bundles 2 into the cans 23.
An RFID antenna 26.1 is assigned to the fiber placement device 22 and reads the RFID chip 24 attached to the barrel 23. The code, preferably formed by a serial number, is contained in the RFID chip 24. The drum 23 thus has a unique identification feature which is picked up by the RFID antenna 26.1 and can be provided to the reading unit 18 of the process control system 17. The fibre parameters obtained during filling of the cans 23, which consist for example of product and process parameters, can be combined with the codes in the process control system 17.
After filling the cans 23, it is sent to a creel 25 together with other filled cans. The RFID chip 24 fixed to the can 23 is obtained in the creel 25 by means of a further RFID antenna 26.2 and is supplied to the process control unit 17 by means of the reading unit 18. The corresponding fibre parameters of the fibre bundle 2 accommodated in the sliver can 23 can be assigned to the transmitted code in the process control system 17 by means of the product data software.
The fibre bundle 2 is drawn from the drum 23 by a drawing unit 28 and supplied to the drawing units 4.1, 4.2. The temperature and humidity control device 5 is also assigned to the drawing units 4.1, 4.2. The further processing for crimping and severing the fibre bundle 2 is identical to the embodiment described above with reference to fig. 1, and is therefore described herein with reference to the above. The bale pressing means 11 at the end of the process is also identical to the above-described embodiment, so that the start time and the end time of forming the bale are obtained by means of a timer 16 and provided to the process control system 17, wherein the identification of the bale 12 is also obtained by means of the RFID antenna 15 and provided to the process control system 17 by means of the reading unit 18.
The product data software within the process control system ensures that the fiber data of the fiber bundle drawn from the cans 23 and other product and process parameters are aggregated into a common product data record and stored in the product database 20 by the respective codes of the packages 12. Each bundle 12 produced may then have its respective product data record retrieved at any time and place by its identifier or code.
In the embodiment shown in fig. 1 and 2, the identifier is assigned directly to the bundle 12. In principle, however, it is also possible to fix an identifier, for example an RFID tag with a code, to pallet 21. The entire transport path of the package may be controlled by the identifier of the pallet 21.
In addition, an RFID tag having an advantage that non-contact authentication can be automatically performed is used for authentication in fig. 1 and 2. But in principle any other identifier may be employed such as for example a QR code or a bar code or other machine readable identifier. The emphasis is that the data record assigned to the product can be assigned to the product by means of the identifier.
