Description

Method and device for operating a large number of

Manufacturing positions for threads

The invention relates to a method for operating a large number of production positions for threads of a melt spinning device and / or a textile machine device and a device for operating a large number of production positions for threads of a melt spinning device and / or a textile machine device according to the preamble of claim 11 .

The production and refinement of synthetic threads takes place in a large number of manufacturing positions, which occupy entire machine shops. For example, in a melt spinning device, large quantities of synthetic threads are produced from a polymer melt by a large number of production positions. For each manufacturing position, a group of threads are spun in parallel from the polymer melt, cooled, stretched and individually wound into threads. Such manufacturing positions are set up next to one another on the longitudinal sides of the machine, a so-called doffing passage being provided between opposite manufacturing positions for the removal of the wound coils. In this way, such manufacturing positions are set up in a multitude to form several openings.

Textile machine equipment, which also has a large number of manufacturing positions, is used in the finishing of synthetic threads. In this case, however, the threads are preferably separated from traces of the original, refined, for example, by texturing and spooled. wrapped. Textile machine devices are known which have over 400 manufacturing positions within an operating aisle, the textile machine devices being arranged next to one another to form several operating aisles.

In such manufacturing positions for threads, manual operations are to be carried out, for which an operator is required. For example, disruptions in the manufacturing process cannot be completely ruled out, which leads to undesired interruptions in individual manufacturing positions, which require quick action and reuse of the manufacturing process. There is also maintenance work that must also be carried out by operating personnel in the production positions. In order to enable the production positions to be operated as efficiently and quickly as possible, DE 10 2017 110 572 A1, for example, discloses a method and a device for operating a multiplicity of production positions for threads, in which a plurality of operating information is available be displayed on a large screen. The large screens are arranged in the operating aisle or doffgang so that the operators located therein quickly have the necessary information and accordingly go to the relevant manufacturing position in order to carry out the operating information. For example, a thread break in a specific manufacturing position could be visualized on the large screen, which requires the thread to be newly applied in the respective manufacturing position. In this case, however, it is necessary that the operator may have to travel a greater distance to the relevant manufacturing position in order to be able to carry out the operating information. However, systems of this type are also known in the prior art, in which the operating personnel serve directly as receivers of operating information. For example, DE 10 2009 022 190 A1 discloses a method for a device for operating a multiplicity of manufacturing positions for threads, in which the operator carries an operating unit with him, which is used for localization and position recognition as well as for receiving operating information is usable. Thus, multiple operators with multiple operating devices could be used to carry out the malfunctions and maintenance work in the manufacturing positions. However, there is the problem that several operators work in parallel to carry out a maintenance or maintenance in one of the manufacturing positions. It is therefore an object of the invention to develop a generic method for operating a large number of manufacturing positions for threads of a melt spinning device and / or a textile machine device and a generic device for operating a large number of manufacturing positions for threads of a melt spinning device and / or a textile machine device such that Targeted and quick implementation of the operating information is guaranteed.

Another object of the invention is to provide a method and a device for operating a large number of production positions for threads, which can be used in particular for large-scale systems with a large number of production positions. This invention is achieved according to the invention by a method with the features according to claim 1 and by a device according to claim 11. Advantageous developments of the invention are defined by the features and combinations of features of the respective subclaims.

The invention is characterized in that the operator always receives operating information that is closest to the respective manufacturing position for carrying out the operating information. This means that very short distances can be covered. In addition, immediate transmission of the operating information to the respective operator is possible without delay. For example, in the event of a fault message in one of the manufacturing positions, one of several transceiver stations is initially determined, which is assigned to the group of manufacturing positions in which the disturbed manufacturing position is located. The operating information of the relevant transceiver station is then transmitted.

The transceiver station forwards the operating information directly to at least one of several assigned message receivers of an operator. By triggering an acknowledgment of receipt to the message recipient by the operator, it is ensured that the operator information has reached the operator. A quick action can thus be carried out in order to remedy the disturbance in the production position.

For this purpose, the operating information can contain direct work instructions for eliminating the fault, for a control action or for example for maintenance. For this purpose, the device for operating a large number of manufacturing positions for threads has a plurality of transceiver stations which are connected to the control device via a network. Each of the transceiver stations can be connected to several signaling receivers via a radio link. In this way, a communication network is implemented via the large number of manufacturing positions, which enables quick and targeted forwarding of operating information.

In order to ensure that the operating information is sent to one of the operating personnel of the entire operating personnel, the method variant is preferably carried out, in which the operating information is only transmitted to the message recipients to whom an operator has already registered. This means that the signal receivers are actively connected to the relevant transceiver station in the radio link, which is assigned to one of the operators. This ensures that the operator receives the operating information.

In the event that the message receivers assigned to the transceiver station have not been activated by an operator, the method variant comes into action in which the receipt confirmation by the operator is expected within a message time at the transceiver station. This gives the operator a reaction time to trigger an acknowledgment of receipt. In the event that no acknowledgment of receipt is received after the reporting time has elapsed, the method variant is particularly advantageous in which the transceiver station generates a warning signal after the reporting time has expired and there is no acknowledgment of receipt. In this way, for example, operating personnel in a break room can be made aware that in their Area of responsibility of one of the manufacturing positions requires operation.

However, the method variant is preferably used in which the operating information is forwarded by the relevant transceiver station to an adjacent transceiver station and in which the operating information is transmitted from there to the assigned message receivers of the adjacent transceiver station. In this way, the circle of addressed operators can be expanded to enable quick implementation of the operating information.

In order that the manufacturing process can be continued immediately after a thread break, for example, it is also provided that the operator triggers an operating confirmation for the relevant transceiver station after successful completion of the operating information on the message receiver. This completes the operation initiated via the control device and can be immediately reported back as having been carried out. Since not all malfunctions, maintenance and other operating work can be carried out by one of the activated operators, the process variant is preferably carried out, in which the operator provides feed-back information to the relevant transceiver if the operating information is not carried out via the message receiver. Station transmitted. In this way, further measures can be initiated to correct the flow or for maintenance.

The procedural variant, in which the transceiver stations with the assigned message receiver each via one of several fixed message Communicating frequencies is particularly advantageous in order to avoid overlaps and overlaps when forwarding operating information. In this way, only the operating information relating to the group of manufacturing positions can be transmitted safely and undisturbed.

Since the various operating processes within the manufacturing positions sometimes require differently qualified operators, it is further provided that the operating information contains an indication of one of several operating categories and that the operators are responsible for one of the operating categories. In this way, the operating information can be split ahead of time according to the operating categories and can be transmitted to the operator responsible for the operating category in a targeted manner.

To this end, it is particularly advantageous if the message receiver only displays the operating information relating to the operating category of the operator. By logging in and logging in the operator to the alarm receiver, the respective operating category can also be recorded at the same time, so that the alarm receiver only displays the operating information suitable for the operator.

The device according to the invention for operating a large number of manufacturing positions for threads is characterized by a simple and interference-resistant communication network for transmitting operating information to the operating personnel.

In order to create the messages required for operation from process monitoring and the parameters determined in the process, according to one advantageous development of the control device is assigned a distribution unit. The distribution unit communicates directly with the transceiver stations in order to transmit the messages generated. So that localized and fast information transmission is possible without complex navigation devices, the further development of the operating device according to the invention is particularly advantageous, in which the transceiver station is assigned to one of several groups of manufacturing positions. By selecting the groups of manufacturing positions and by selecting the number of transceiver stations, corresponding, precise, localized operating information can be transmitted.

To take over the message receivers from the operating personnel, it is further provided that the message receivers which are assigned to one of the transceiver stations are held in a charging station and can optionally be removed from the charging station by an operator. This ensures the assignment between the message receivers and the transceiver stations. Each operator therefore has the task of placing the message recipient at the relevant charging station at the end of the work. In addition, the batteries of the message recipient can be recharged during idle time.

In addition, overlapping and misdirection of the operating information is precluded because the radio connections between the transceiver stations and the message receivers have different message frequencies. Communication between different devices is not possible. In order to enable quick operation and handling of the message receiver, it is designed at least with a confirmation key and an acknowledgment key, so that the operator only has to press one key to trigger an acknowledgment of receipt or to trigger an operator confirmation.

In addition, the development of the operating device according to the invention, in which the message receivers each have login software for logging in an operator, enables the message receiver to be personalized. In this way, only the operating information that the respective operator should receive can be displayed by the message recipient.

The method according to the invention for operating a large number of manufacturing positions for threads and the operating device according to the invention are particularly suitable for large systems of melt spinning devices and textile machine devices in order to implement operating management in a large number of manufacturing positions. The method according to the invention for operating a multiplicity of manufacturing positions for threads is explained in more detail below on the basis of some exemplary embodiments of the operating device according to the invention with reference to the attached figures.

They represent: 1 schematically shows a side view of a first exemplary embodiment of a melt spinning device with the operating device according to the invention, FIG. 2 schematically shows a top view of the exemplary embodiment from FIG. 1,

FIG. 3 schematically shows a view of a message receiver of the operating device from FIGS. 1 and 2, FIG. 4 schematically shows a top view of a further exemplary embodiment of a textile machine device with an operating device according to the invention.

1 and 2 schematically show a first exemplary embodiment of a melt spinning device with a multiplicity of production positions for threads in a side view and in a plan view with an operating device according to the invention for operating the multiplicity of production positions. In Figure 1, the side view of the melt spinning device is shown schematically, which extends over several floors. In this exemplary embodiment, only the devices required for producing the synthetic threads are shown. A spinneret device 7 and a cooling device 8 are located on an upper floor. The spinneret device 7 is connected to a device for producing a polymer melt, which is not shown in this exemplary embodiment.

The take-up devices 9 are provided in the lower level in order to draw and wind the freshly spun and cooled threads to wrap. Such a melt spinning device is well known and is described, for example, in DE 10 355 294 A1. Insofar, no further explanation is given at this point about the melt spinning device and instead reference is made to the cited publication.

The spinneret device 7, the cooling device 8 and the takeup device 9 have a large number of production positions. In this exemplary embodiment, the first five production positions are identified by the reference numbers 10.1 to 10.5. The manufacturing positions 10.1 to 10.5 and the following extend along a longitudinal side of the machine. The number of manufacturing positions is divided into several groups, with one group comprising five manufacturing positions.

As can be seen from the illustration in FIG. 2, the take-up devices 9 lying opposite form a doffing passage 15 between the production positions 10.1 to 10.5 and 10. G to 10.5 '. The doffing passage 15 serves to remove the wound coils in the take-up devices 9.

As can be seen from the illustrations in FIG. 1 and FIG. 2, the manufacturing positions are divided into a plurality of groups. The groups of the manufacturing positions are identified by the reference symbols Hi to Hio. Each of the manufacturing groups of manufacturing items Hi through H io comprises a total of five manufacturing items. In each manufacturing position, a plurality of threads are spun, cooled, drawn and wound into bobbins at the same time. Today's manufacturing positions are known that produce 32 threads in parallel next to each other. In order to serve the large number of manufacturing positions in the manufacturing groups H1 to H10, the operating device according to the invention has a plurality of transceiver stations 3.1 to 3.10. Each of the transceiver stations 3.1 to 3.10 is assigned to a group of manufacturing positions H1 to H10. For example, the manufacturing positions 10.1 to

10.5 assigned to the upper floor of the transceiver stations 3.1. The five manufacturing positions 10.1 to 10.5 form the manufacturing group Hl.

In this respect, the transceiver stations 3.1 to 3.10 are assigned to the manufacturing groups from manufacturing positions Hi to Hi. The transceiver

Stations 3.1 to 3.10 are held stationary and connected to a distribution unit 19 via a network 2. The distribution unit 19 is coupled to a control device 1. The control device 1 can be part of a process control unit of the entire melt spinning device. In this respect, it has inputs and outputs in order to be able to record and output information from process monitoring and process manufacturing.

As can be seen from the representations in FIG. 1 and FIG. 2, the transceiver stations 3.1 to 3.10 are each assigned a plurality of message receivers 5.1 and 5.2. The number of signal receivers 5.1 and 5.2 is exemplary and depends on the number of operators who have to perform different operations at the manufacturing positions 10.1 to 10.5. The signal receivers are mobile and are taken over and operated by the operating personnel as handheld devices. For example, the message receivers 5.1 and 5.2 assigned to the transceiver stations 3.1 to 3.10 could each be assigned a charging station 4.1 to 4.10. The operating personnel is thus able to have a message receiver 5.1 or 5.2 at the start and end of the shift to remove or deliver. The signal receivers 5.1 and 5.2 are charged in the charging stations 4.1 to 4.10, respectively.

The signal receivers 5.1 and 5.2 are connected to the transceiver stations 3.1 to 3.10 via a radio link. In this case, the radio connections 6.1 to 6.10 between the transceiver stations 3.1 to 3.10 and the message receivers 5.1 and 5.2 are preferably each operated with different message frequencies. This ensures a defined assignment between the message receivers 5.1 and 5.2 and the transceiver stations 3.1 to 3.10.

To explain the message receivers 5.1 and 5.2, reference is made in addition to FIG. 3. FIG. 3 schematically shows a view of an exemplary embodiment of the message receiver 5.1. The message receiver 5.1 is designed as a handheld device and could, for example, be based on an operating system with Android technology. The message receiver is designed as a receiving device and as a sending device for receiving operating information and for delivering information. For this purpose, the message receiver 5.1 has a display 11. A confirmation key 12, an acknowledgment key 13 and a menu key 14 are provided below the display 11.

The actuation button 12 can be used to confirm receipt of operator information by the operator vis-à-vis the transceiver station. The acknowledgment button 13 enables a quick confirmation of operation when the operations requested by the operating information have been successfully carried out by the operator. The menu button 14 enables further transmission functions, for example to send feedback information to the responsible person if the operating information is not carried out Transceiver station to transmit. In addition, the message receiver 5.1 has a login software with which an operator has to log on to the device. In operation, the message receivers 5.1 and 5.2 are carried by one operator each, who is used within the melt spinning device to carry out operating activities. In the event that an error message is received in the control device 1 that there is a thread break in the manufacturing position 10.5 of the manufacturing group H ₅ , the distribution unit 19 first creates operating information and determines the transceiver station in question. In this case, the transceiver station 3.5 is responsible for transmitting operating information regarding the cause of the error. To generate the operating information, the distribution unit 19 can have a plurality of software modules which determine the necessary operating measures from the parameters of the process monitoring.

The distribution unit 19 sends the operating information via the network 2 directly to the transceiver station 3.5. Via the radio link 6.5, the operating information is transmitted by the transceiver station 3.5 to one or both signal receivers 5.1 and 5.2. Only the message receiver 5.1 and 5.2, which is operated by an operator, receives the operating information.

The operator, who captures and records the operating information, will now press the actuation button 12 on the message receiver, so that the transceiver station 3.5 is informed about the correct delivery of the operating information. No further actions are therefore initiated. The operator must now hurry to manufacturing position 10.5 to correct the yarn breakage errors and to restart the manufacturing process. As soon as the operator executes the operating information and the manufacturing process can be continued, the acknowledgment button 13 is actuated on the message receiver, so that the information about the transceiver station 3.5 of the distribution unit 19 and above it can be fed to the control device 1. The fault has now been resolved.

In the event that none of the message receivers 5.1 and 5.2 is activated by an operator, the transceiver station 3.5 will generate a warning signal after a message time of, for example, one minute. The warning signal could, for example, be an acoustic or visual signal to neighboring operators or those in a break

To address operators.

In parallel, however, the operating information is passed on directly to an adjacent transceiver station, in this case the transceiver station 3.6, so that the transceiver station 3.6 can transmit the operating information to the assigned message receivers 5.1 and 5.2. In this case, the neighboring operating personnel are involved in order to remedy the fault in manufacturing position 10.5 as quickly as possible. Due to the diverse operating activities, operators with different qualifications are employed in such melt spinning devices. It is common, for example, that in the spinneret devices 7 the spinnerets used for extruding the filaments in regular intervals on the underside. Such scraping is carried out by maintenance personnel.

The operations required to guide the thread are usually carried out by an operator. In order to be able to address the responsible operating personnel as far as possible during the transmission of the operating information, it is possible for the operating information to be given additional information, for example in the form of a prefix, by the distribution unit 19. The reference refers to one of several operating categories, for example maintenance work, repair, process management, etc., which are carried out by specially trained operating personnel. For example, the operating categories A, B and C could be selected, which would be added to the operating information by corresponding letters A, B, C.

In the event that the operating information is now assigned to operating category A, this operating information would only appear on a message receiver if the message recipient is managed by an operator with responsibility for operating category A. In the event that the relevant message receiver is responsible for service category C, the user information transmitted by the transceiver station would not be shown on the display 11 of the message receiver. This ensures that the operating information that is assigned to certain operating activities and thus to certain operating categories is transmitted in a targeted manner to the responsible operating personnel.

The exemplary embodiment of the operating device according to the invention shown in FIGS. 1 and 2 is therefore particularly suitable for operating complex melt spinning devices quickly and in a targeted manner. Here All types of melt spinning devices can be included, regardless of whether the threads are wound into bobbins, laid down as spinning cables or chopped into staple fibers. The devices for melt production can advantageously be integrated here, so that faults, for example in a polycondensation, can also be quickly eliminated.

Basically, the inventive operating device and the inventive method for operating a large number of manufacturing positions for threads are also suitable for complex textile machine devices which require a large number of operating personnel due to the large number of manufacturing positions. For this purpose, an exemplary embodiment of a textile machine device is shown schematically in a top view in FIG. The textile machine device is formed by a creel device 16, a process device 17 and a winding device 18. The gate device 16, the process device 17 and the winding device 18 extend along a doffing path 15, which is arranged on the longitudinal side of the machine of the winding devices 18. The textile machine device shown could thus be a so-called false twist texturing machine, in which, for each production position 10.1, a thread is drawn from a supply spool in the creel device 16, stretched and textured in the process device 17 and wound up into a spool in the winding device 18 becomes. Such textile machine devices are well known and are described, for example, in the publication DE 10 2013 109 530 A1. In this respect, no further explanations are given here. given to the textile machine equipment and instead referred to the cited publication.

In the exemplary embodiment shown in FIG. 4, the first twelve manufacturing positions 10.1 to 10.12 each form a group of manufacturing positions. The groups of manufacturing positions are marked with the reference times Hi to H ₄ . For each of the production groups Hi to H ₄ , the operating device according to the invention has a transceiver station 3.1 to 3.4. The transceiver stations 3.1 to 3.4 are connected via a network 2 to a distribution unit 19 which is coupled to a control device 1. The control device 1 could, for example, be coupled to a process control in order to receive information on the monitoring and production of the threads in the production positions.

Each of the transceiver stations 3.1 to 3.4 are assigned several message receivers. In this exemplary embodiment, too, only two message receivers 5.1 and 5.2 per transceiver station 3.1 to 3.4 are shown. The signal receivers 5.1 and 5.2 are kept in a charging station 4.1 to 4.4 in order to be taken over by an operator. The function of the message receivers 5.1 and 5.2 is identical to that of the aforementioned embodiment according to FIG. 3. The number of message receivers that is assigned to one of the transceiver stations depends on the operating personnel. In principle, more than two message receivers can be provided per transceiver station.

In this respect, the function for operating the manufacturing positions of the manufacturing groups Hi to H _{4 is} identical to the aforementioned exemplary embodiment. The operating device according to the invention and the method according to the invention for operating a multiplicity of manufacturing positions are thus advantageously suitable in order to be able to operate complex textile machine devices with a multiplicity of manufacturing positions as quickly and efficiently as possible. Different operating categories can also improve operating management here.
