Definitions
- the invention relates to a melt spinning process for the production of synthetic staple fibers according to the preamble of claim 1 and a melt spinning device for the production of synthetic staple fibers according to the preamble of claim 9.
- a generic melt spinning process and a generic melt spinning device for producing synthetic staple fibers are known, for example, from DE 10 2017 100 592 A1.
- such staple fibers can be carried out continuously from the spinning device to the formation of bales or discontinuously through a storage of the fiber strands.
- DE 10 2017 100 592 discloses a discontinuous melt spinning device in which the fiber strands are first deposited in cans. The cans are then grouped into several cans in a can creel in order to pull all the fiber strands from the cans simultaneously and process them into staple fibers.
- Such complex melt-spinning processes and melt-spinning devices result from monitoring process parameters and product parameters large amounts of data that could be assigned to the staple fibers produced.
- each of the bales receives an individual, machine-readable identifier and that the identifier of the bale, a start time of bale formation and an end time of bale formation are transmitted to the process control system.
- the solution results from the fact that the baling device is assigned an identifier for providing a machine-readable identifier per bale or a pallet equipped with a machine-readable identifier for receiving the ball.
- the invention has the particular advantage that the bales with the staple fibers are marked exclusively by an individual identification that is machine-readable and can be fed electronically to the process control system or other machine control units.
- the staple fibers collected in the bale during bale formation can also be clearly identified in their manufacture.
- the development of the method according to the invention is preferably carried out in which several process and / or product parameters recorded during a period between the start time and the end time of the bale formation are combined into a product data record and the product data record is assigned to the identification of the relevant bale.
- the product data record can be assigned to the relevant staple fibers using the code on the bale. For example, when the bales are packaged, a data printout could be generated via the label, which would be attached to the delivery papers.
- the method variant is particularly advantageous in which an encoded RFID label is attached to the bale as the identification.
- a code can thus be recorded automatically and without contact to identify the bale with the help of electromagnetic waves.
- the method variant is preferably implemented in which the product data record is stored in a product data database under the code of the RFID label.
- product databases which could for example be contained in a cloud, are always accessible, so that the product data of the staple fibers can be called up at any time using the code of the bale.
- the method variant is provided in which the fiber strands are temporarily stored in cans after extrusion and in which each of the cans is coded by an RFID chip. By simply coding the can, it can be used multiple times to temporarily store fiber strands.
- the fiber parameters assigned to the codes of the cans are jointly assigned to the product data set of the bale, so that even with a discontinuous melt spinning process all relevant process steps for the production of the staple fibers are contained in the product data set.
- the fiber parameters assigned to the codes of the cans are jointly assigned to the product data set of the bale, so that even with a discontinuous melt spinning process all relevant process steps for the production of the staple fibers are contained in the product data set.
- the melt-spinning process is characterized by the fact that the individual, machine-readable identifiers required for identifying the bales are immediately available through an identifier and can be added to the bales. Alternatively, such labels can also be attached directly to pallets that are used to hold the bales. The staple fibers contained therein can be identified by labeling the bale or pallet.
- the baling device In order to connect the staple fibers fed in during bale formation with the continuously recorded product and process parameters, the baling device has a timer connected to the process control system, by means of which a start time and an end time for forming the bale can be recorded.
- the product data and / process data recorded during the period during which the bale was formed can thus be assigned to the bale via the identifier.
- the development of the melt spinning device is preferably implemented in which the identifier is formed by an RFID label that is implemented with a code.
- the unique code on the RFID label ensures that the bale can be clearly identified.
- An RFID antenna connected to the process control system is provided to transmit the code. This means that pre-labeled pallets can also be used to pick up a bale.
- the development of the He-making is provided in which several cans for receiving fiber strands are provided that each carry an RFID chip and in which a fiber storage device for filling cans has an RFID antenna that is connected to the process control system.
- the RFID chip can be permanently connected to the edge, so that the coding contained therein can be used repeatedly to identify the fiber strands stored in the can.
- a can gate for receiving the cans has at least one further RFID antenna which is connected to the process control system.
- the RFID antennas are each connected to a reading unit of the process control system by a coaxial cable.
- the coding of the RFID chips and the codes of the RFID labels can be fed to the process control system.
- each of the RFID antennas is identified according to an advantageous development of the invention by a location address that is stored in the process control system.
- the codes of the RFID labels and / or the codes of the RFID chips are preferably formed by an individual serial number. Measures for generating a code or coding can thus be avoided.
- the further development of the invention is particularly advantageous in which the process control system has at least one product database and product data software through which stored product data can be combined with the code of the bale. This ensures that the seldom codes of the bale encoded data are available for further processing of the thread of the processing station.

- the fiber strands 2 are conditioned by the conditioning device 5, for example by a water bath.
- the fiber strands 2 can be post-treated by a calender device after drawing.
- the fiber strands are brought together by the laying device 6 to a working width for the crimping device 7 and crimped by the crimping device 7.
- the fiber strands are then cut up by the cutting device 10 to form the staple fibers 27.
- the staple fibers 27 are then compressed to form a bale 12.
- a start time of the bale formation is recorded via the timer 16 and transmitted to the process control system 17.
- an end time of the bale formation is fed to the process control system 17 via the timer 16.
- the process and / or product parameters recorded during the period between the start time and the end time of the bale formation are combined to form a product data set.
- An RFID label 13 is generated by the identifier 14 and fed to the bale 12.
- the code contained in the RFID label 13 is detected by the RFID antenna 15 and fed to the reading unit 18.
- the code of the ball 12 is forwarded to the process control system 17, which links the relevant product data set with the code.
- An existing serial number of the RFID label can be used as a code.

- the product database 20 can be formed by a cloud, for example.
- the product data record can be called up at any time and from any location via the identifier of the bale 12 and the associated coding.
- the merging of the product and process data within the duration of the bale formation is carried out using product data software that is contained within the process control system 17. This means that all process and product parameters monitored and recorded during the manufacturing process can be assigned to the staple fibers. The throughput times of the fiber strands until they are cut are taken into account.

- RFID labels are used for identification, the advantage of which is the automatic and contactless identification option.
- other identifiers such as a QR code or a barcode or other machine-readable identifiers can also be used. It is essential here that the data record to be assigned to a product can be assigned to the product via the identifier.
