Description

INDUSTRIAL APPLICABILITY The present invention relates to a method for operating a large number of manufacturing positions for a plurality of yarns of a melt spinning device and / or a textile mechanical device, and a melt spinning stop device of the type according to the premise of claim 11. And / or with respect to a device for manipulating a large number of manufacturing positions for multiple threads of a textile mechanical device.

Manufacture and processing of synthetic yarns take place in a number of manufacturing locations that occupy the entire machine shop. Thus, for example, in a melt spinning apparatus, a large amount of synthetic yarn is formed from the polymer melt by a large number of production positions. At each production position, yarn groups are spun from the polymer melt in parallel, cooled, stretched and individually wound to form yarns. Such manufacturing positions are installed side by side on the longitudinal side of the machine. Between the facing manufacturing positions, there is one so-called doffer passage for carrying out the wound package. Therefore, a large number of such manufacturing locations are installed to form the plurality of Doffer passages.

When processing synthetic yarns, a plurality of textile mechanical devices are used. These textile machinery also have a large number of manufacturing positions. However, the yarn is preferably individually stored and drawn from the bobbin, processed, for example by texturing, and wound to form a package. Therefore, a textile mechanical device having more than 400 manufacturing positions in one operating passage is known, and the textile mechanical device is arranged side by side in a plurality of operating passages.

In such manufacturing positions for multiple yarns, manual operation must be performed, which requires an operating operator. Thus, for example, obstacles in the manufacturing process cannot be completely eliminated, resulting in unwanted interruptions at individual manufacturing locations. This interruption requires prompt action and resumption of the manufacturing process. Further, maintenance work that must be carried out by the operation operator at the manufacturing position also occurs.

In order to enable the most efficient and quick operation of the production position, for example, from German Patent Application Publication No. 1020171110572, a method for operating a large number of production positions for multiple yarns and The device is known. In this method, a plurality of operation information is displayed on one large screen. The large screen is located in the operating aisle or Doffer aisle, so that the operating operator in this aisle can quickly obtain the required information, correspondingly visit the relevant manufacturing location and execute the operating information. can do. Thus, for example, yarn breaks at one particular manufacturing location can be visualized on a large screen. Thread breaks require a new thread to be hung at each manufacturing position. However, the operating operator is sometimes required to travel a relatively large distance to the relevant manufacturing location in order to be able to perform the operational information.

However, in the prior art, a system in which an operation operator directly acts as a receiver of operation information is also known. Thus, for example, from German Patent Application Publication No. 10209022190, methods and devices for manipulating a large number of production positions for a plurality of yarns are known. In this method, the operating operator carries an operating unit that can be used for localization and location determination as well as receiving operational information. Therefore, it is possible to deploy a plurality of operating operators equipped with a plurality of operating devices, thereby performing failures and maintenance work at the manufacturing location. However, in this case, there arises the problem that a plurality of operating operators act in parallel at the same time in order to perform a failure and maintenance in one of the plurality of manufacturing positions.

Therefore, the subject of the present invention is the method of the form described at the beginning for manipulating a large number of production positions for a plurality of yarns in a melt spinning device and / or a textile mechanical device, and a melt spinning device and /. Or improvements to the equipment mentioned at the beginning for manipulating multiple manufacturing positions for multiple yarns in textile machinery to ensure that the operation information is as purposeful and quick as possible. To be there.

Another object of the present invention is to provide a method and apparatus for manipulating a large number of production positions for a plurality of yarns, which can be used especially for large plants with a large number of production positions. There is something in it.

According to the present invention, this problem is solved by the method provided with the feature according to claim 1 and the apparatus provided with the feature according to claim 11.

Advantageous improvements of the invention are defined by the features and combinations of features described in their respective dependent claims.

The present invention is superior in that the operation operator closest to each manufacturing position always receives the operation information in order to execute the operation information. Therefore, an extremely short distance can be realized. Further, the operation information can be directly transmitted to each operation operator without delay. So, for example, if a failure is reported at one of the manufacturing locations, the transceiver station that is assigned to the group of manufacturing locations with the failed manufacturing location is first identified among the plurality of transceiver stations. Will be done. Operational information is then transmitted to the associated transceiver station.

The transceiver station transmits the operation information directly to at least one of the operator's assigned message receivers. By confirming reception at the message receiver by the operation operator, it is ensured that the operation information has arrived at the operation operator. This allows rapid action to be taken to remove obstacles in the manufacturing position.

To this end, the operational information may include direct work instructions for removing obstacles, control actions, or work instructions for, for example, maintenance.

For this purpose, the device for performing operations on a large number of manufacturing positions for a plurality of yarns has a plurality of transceiver stations connected to the control device via a network. Each transceiver station can connect to multiple message receivers via a wireless connection. Therefore, a communication network over a large number of manufacturing locations has been realized, and this communication network enables rapid and purposeful transmission of operational information.

In order to ensure that the operation information is delivered to the operation operator of one of the entire operation personnel, a method variation of transmitting the operation information only to the message receiver to which the operation operator is already logged in is preferably implemented. Has been done. This allows the message receiver to be actively connected in a wireless connection to the associated transceiver station assigned to one of the operator's operators. This guarantees that the operation operator receives the operation information.

If the message receiver assigned to the transceiver station is not activated by the operating operator, a variation of the method of waiting at the transceiver station for receipt confirmation by the operating operator within a predetermined reporting time is used. As a result, the operation operator is given a reaction time for confirming reception.

A variation in the method in which the transceiver station emits a warning signal if the reception confirmation is not received after the reporting time has elapsed and if the reception confirmation is not performed after the reporting time has elapsed is particularly advantageous. Thereby, for example, the operation operator in the break room can be made aware that one of the plurality of manufacturing positions within the range in charge requires operation.

However, preferably, a variation of the method is used in which the operation information is transmitted to the next transceiver station by the related transceiver station, and the operation information is transmitted from the next transceiver station to the assigned message receiver of the next transceiver station. Will be done. As a result, the range of operation operators to be called can be expanded, which enables rapid execution of operation information.

In addition, the operating operator confirms the operation for the associated transceiver station in the message receiver after the successful completion of the performed operational information so that the manufacturing process can be continued immediately after, for example, thread breakage. Is stipulated. This reports that the operation initiated through the controller is finished and executed immediately.

All failures, maintenance and other operational tasks cannot be performed by one of the active operating operators, so that the operating operator may not perform the operational information via the message receiver. , A variation in the method of propagating feedback information to the associated transceiver station is preferably implemented. Therefore, another measure can be initiated to remove or maintain the fault.

A variation on how the transceiver station communicates with the assigned message receiver over the message frequency of one of multiple fixed message frequencies each to avoid overlap and duplication in the transmission of operational information. Especially advantageous. As a result, only the operation information related to the group of manufacturing positions can be transmitted safely and without any obstacles.

Since the various different operating processes within the manufacturing location require operating operators with partially different qualifications, the operating information includes instructions for one of the plurality of operating categories, the operating operator. However, it is further stipulated that each of the operation categories is in charge of one operation category. Therefore, the operation information can be divided in advance according to the operation category and transmitted to the operation operator in charge of the operation category according to the purpose.

For this purpose, it is particularly advantageous for the message receiver to display only the operation information related to the operation category of the operation operator. Since each operation category is also grasped at the same time through the sign-in and login of the operation operator in the message receiver, only the operation information suitable for this operation operator is displayed in the message receiver.

The apparatus according to the present invention for performing operations on a large number of manufacturing positions for a plurality of yarns is superior to a simple and unobstructed communication network for transmitting operation information to an operation operator.

As a further advantageous deployment, a distribution unit is assigned to the controller, according to the advantageous improvement, to generate the messages required for operation based on process monitoring and required parameters. The distribution unit communicates directly with the transceiver station to convey the generated message.

A book in which each transceiver station is assigned to one of several groups of manufacturing locations to enable rapid localized communication without the use of tedious navigation equipment. The improved version of the operating device according to the invention is particularly advantageous. The selection of a group of manufacturing locations and the selection of the number of transceiver stations can convey the corresponding accurately localized operational information.

The message receiver assigned to one of the transceiver stations for picking up the message receiver by the operating operator is held in the charging station and selectively charged by one operating operator. It is further stipulated that they be taken out of the station. This guarantees the allocation between the message receiver and the transceiver station. Therefore, each operator has the task of returning the message receiver to the associated charging station at the end of work. In addition, the storage battery of the message receiver can be charged outside of operating hours.

Further, overlap of operation information and erroneous transmission are eliminated. This is because the wireless connection between the transceiver station and the message receiver has different message frequencies. This makes it impossible to communicate between devices in different groups.

In order to enable quick operation and handling of the message receiver, the message receiver is provided with at least one confirmation button and an end button, whereby the operation operator can confirm the reception and confirm the operation. You only have to press one button to do this.

Further, an improved version of the operating device according to the present invention, in which the message receiver has login software for login of the operating operator, respectively, enables personalization of the message receiver. Therefore, only the operation information to be received by each operation operator is displayed by the message receiver.

The method according to the present invention for performing an operation on a large number of manufacturing positions of a plurality of yarns and the operating device according to the present invention are a melt spinning device and a textile machine device for performing operation management at a large number of manufacturing positions. Especially suitable for large plants.

A method according to the present invention for manipulating a large number of manufacturing positions for a plurality of yarns will be described in detail below with reference to some embodiments of the operating apparatus according to the present invention with reference to the accompanying drawings. do.

It is a side view schematically showing the 1st Embodiment of the melt spinning apparatus provided with the operation apparatus which concerns on this invention. It is a top view which shows the embodiment shown in FIG. 1 schematically. It is a schematic diagram which shows the message receiver of the operation apparatus shown in FIG. 1 and FIG. It is a top view schematically showing another embodiment of the textile mechanical apparatus provided with the operation apparatus which concerns on this invention.

A first embodiment of a melt spinning apparatus with a large number of production positions for a plurality of yarns is schematically illustrated in a side view in FIG. 1 and an operation for a large number of production positions in FIG. It is schematically illustrated in a plan view together with the operating device according to the present invention for performing.

FIG. 1 schematically shows a side view of a melt spinning apparatus extending over a plurality of layers. In this embodiment, only the equipment required to manufacture synthetic yarns is shown. Therefore, the spinning nozzle device 7 and the cooling device 8 are located on the upper floors. The spinning nozzle device 7 is connected to a device for forming a polymer melt (not shown in this embodiment).

A take-up device (Takeup-Einrichtung) 9 is provided in the lower layer. This allows the yarn that has just been spun and cooled to be drawn and wound to form a package. Such melt spinning devices are well known and are described, for example, in German Patent Application Publication No. 10355294. To that extent, no further description of the melt spinning apparatus is given here, but instead the cited patent literature is referenced.

The spinning nozzle device 7, the cooling device 8, and the take-up device 9 have a large number of manufacturing positions. In this embodiment, reference numerals 110 to 10.5 are attached to the first five manufacturing positions. The manufacturing position 10.1 to 10.5 and the subsequent manufacturing location extend along the machine longitudinal side. Multiple manufacturing sites are divided into multiple groups. In this example, one group exemplaryly comprises five manufacturing sites.

As can be seen from the plan view of FIG. 2, the winding device 9 facing the manufacturing positions 10.1 to 10.5 and 10.1'to 10.5' forms a doffer passage 15. The doffer passage 15 works to carry out the package wound in the winding device 9.

As can be seen from the drawings of FIGS. 1 and 2, the manufacturing positions are divided into a plurality of groups. A group of production position, reference numeral _H 1 _{to H 10} are attached. Each of the plurality of manufacturing groups H _{1 to} H ₁₀ in the manufacturing position contains a total of 5 manufacturing positions. At each manufacturing position, multiple yarns are spun, cooled, stretched and wound at the same time to form a package. Therefore, today's manufacturing position is known, in which 32 threads are formed side by side in parallel.

For performing an operation for a number of production locations within the fabrication group _H 1 _{to H 10,} the operating device according to the present invention includes a plurality of transceiver stations 3.1 to 3.10. Each transceiver station of the plurality of transceiver station 3.1 to 3.10 is assigned to a group _H 1 _{to H 10} of the production position. Therefore, for example, the manufacturing position 10.1 to 10.5 on the upper floors is assigned to the transceiver station 3.1. Five production position 10.1 to 10.5 form a manufacturing group _{H 1.}

To this extent, the in production position of each manufacturing group _H 1 _{to H 10,} transceiver station 3.1 to 3.10 are assigned. The transceiver stations 3.1 to 3.10 are held stationary and connected to the distribution unit 19 via the network 2. The distribution unit 19 is connected to the control device 1. The control device 1 may be a component of the process control unit of the entire melt spinning device here. To that extent, the control device 1 has an input unit and an output unit so that information regarding process monitoring and process manufacturing can be received and transmitted.

As can be seen from the drawings of FIGS. 1 and 2, each of the transceiver stations 3.1 to 3.10 is assigned a plurality of message receivers 5.1 and 5.2. The number of message receivers 5.1 and 5.2 is exemplary and depends on the number of operating operators who must perform a variety of different operations at manufacturing positions 10.1 to 10.5. The message receiver is configured to be mobile and is taken over and carried by the operator as a handheld device. Therefore, for example, for each of the message receivers 5.1 and 5.2 assigned to the transceiver stations 3.1 to 3.10, they are arranged in one charging station 4.1 to 4.10, respectively. good. Therefore, the operation operator can take out or return one message receiver 5.1 or 5.2 at the start of the shift work and at the end of the shift work, respectively. In the charging stations 4.1 to 4.10, the message receivers 5.1 and 5.2 are charged, respectively.

The message receivers 5.1 and 5.2 are connected to the transceiver stations 3.1-3.10 via a wireless connection. The wireless connections between the transceiver stations 3.1-3.10 and the message receivers 5.1 and 5.2 are preferably made at different message frequencies from each other. Therefore, a defined allocation between message receivers 5.1, 5.2 and transceiver stations 3.1-3.10 is guaranteed.

FIG. 3 is additionally referred to to illustrate the message receivers 5.1 and 5.2. FIG. 3 shows a schematic diagram of an embodiment of the message receiver 5.1. The message receiver 5.1 is configured as a handheld (mobile) device and may be based on, for example, an operating system using Android technology. The message receiver is designed as a receiver for receiving operation information and as a transmitter for transmitting information. For this purpose, the message receiver 5.1 has a display 11. Below the display 11, a confirmation button 12, an end button (Quittierungstaste) 13, and a menu button 14 are provided.

The confirmation button 12 confirms the receipt of the operation information by the operation operator with the transceiver station. The end button 13 enables quick operation confirmation when the operation content requested by the operation information is normally executed by the operation operator. The menu button 14 enables another transmit function, for example, to convey feedback information to the associated transceiver station if no operational information has been executed. Further, the message receiver 5.1 has login software, and the operator must log in to this device using this login software.

During operation, the message receivers 5.1 and 5.2 are carried by an operation operator who is arranged to perform the operation contents in the melt spinning apparatus each time. If an error message that the yarn breakage is present in the preparation position 10.5 of manufacturing group H ₅ arrives to the control apparatus 1, the dispensing unit 19, is first operation information created, associated transceiver stations are identified. In this case, the transceiver station 3.5 carries out the transmission of operational information related to the cause of the error.

The distribution unit 19 may have a plurality of software modules in order to create operation information. These software modules determine the required operational actions based on the process monitoring parameters.

The distribution unit 19 transmits the operation information directly to the transceiver station 3.5 via the network 2. Operation information is transmitted by the transceiver station 3.5 to one or both of the message receivers 5.1 and 5.2 via the wireless connection 6.5. Only the message receivers 5.1 and 5.2 carried by the operation operator receive the operation information.

The operation operator who grasps and receives the operation information operates the confirmation button 12 provided on the message receiver, whereby the transceiver station 3.5 confirms the normal delivery of the operation information. Therefore, another action is not initiated and the operator can immediately rush to the manufacturing position 10.5, thereby eliminating the thread break error and restarting the manufacturing process.

As soon as the operation operator executes the operation information and the manufacturing process can be continued, the end button 13 is operated in the message receiver, thereby moving to the distribution unit 19 via the transceiver station 3.5 and further to the control device 1. Information can be supplied to. Now the obstacles have been removed.

In case neither of the message receivers 5.1 and 5.2 is activated by the operating operator, the transceiver station 3.5 emits a warning signal, for example after one minute of reporting time. The warning signal may be an acoustic signal or a visual signal, for example, to call the next operator or the operator during a break.

However, since the operation information is transmitted directly in parallel to the adjacent transceiver station (in this case, the transceiver station 3.6), the transceiver station 3.6 transfers the operation information to the assigned message receiver 5.1. , 5.2 can be transmitted. In this case, the next operator is involved in order to resolve the obstacle at manufacturing position 10.5 as soon as possible.

In connection with various operation contents, operation operators with various different qualifications are assigned to this type of melt spinning apparatus. Therefore, for example, in the spinning nozzle device 7, the lower surface of the spinning nozzle used for extrusion of the filament is generally cleaned periodically. Such scraping is performed by a maintenance operator.

The operations required to guide the thread are usually performed by an operating operator. The distribution unit 19 can provide additional instructions, for example in the form of a prefix, to the operation information so that the operation operator in charge can be called as much as possible when transmitting the operation information. This instruction relates to one of a plurality of operation categories, such as maintenance work, repair, process management, performed by a specially trained operation operator. Thus, for example, operation categories A, B and C may be preselected and these operation categories are added to the operation information by the corresponding alphabetical instructions A, B, C.

Now, when the operation information is assigned to the operation category A, this operation information is displayed in the message receiver only when the message receiver is carried by the operation operator in charge of the operation category A. If the associated message receiver is for operation category C, the operation information transmitted from the transceiver station will not be displayed on the display 11 of this message receiver. This guarantees that the operation content assigned to a specific operation content and, by extension, the operation information assigned to a specific operation category is transmitted to the operation operator in charge according to the purpose.

Therefore, the embodiments of the operating device according to the present invention shown in FIGS. 1 and 2 are particularly suitable for operating a complex melt spinning device in a rapid and purposeful manner. This includes all types of melt spinning equipment, whether the yarn is wound to form a package, deposited as a sliver, or cut to form a staple fiber.

An apparatus for melt formation is also advantageously included, whereby obstacles in polycondensation, for example, can be quickly eliminated.

Basically, the operating apparatus according to the present invention and the method according to the present invention for operating a large number of manufacturing positions for a plurality of yarns are complicated and require a plurality of operating operators due to a large number of manufacturing positions. Also suitable for textile machinery.

For this purpose, in FIG. 4, an embodiment of a textile mechanical device is schematically shown in a plan view. The textile mechanical device is composed of a creel device 16, a process device 17, and a winder device 18. As used herein, the creel device 16, the process device 17, and the winder device 18 extend along a doffer passage 15 located on the machine longitudinal side of the winder device 18. Therefore, in the illustrated textile mechanical device, one thread is unwound from one storage bobbin of the creel device 16 for each manufacturing position 10.1, stretched in the process device 17, textured, and wounder device. It may be a so-called false twist textured machine that is wound at 18 to form a package. This type of textile machinery is well known and is described, for example, in German Patent Application Publication No. 102013109530. To that extent, no further description of textile machinery is given here, but instead the cited patent literature is referenced.

In the embodiment shown in FIG. 4, the first 12 manufacturing positions 10.1-12, respectively, form one group of manufacturing positions. A group of production position, reference numeral _H 1 to H ₄ are attached. For each production group of a plurality of production groups _H 1 to H _4, the operating device according to the present invention has a single transceiver stations 3.1 to 3.4. The transceiver stations 3.1 to 3.4 are connected to the distribution unit 19 connected to the control device 1 via the network 2. The control device 1 may be connected to, for example, a process control device in order to monitor the yarn at the manufacturing position and obtain information related to manufacturing.

A plurality of message receivers are assigned to each of the transceiver stations 3.1 to 3.4. Also in this embodiment, only two message receivers 5.1 and 5.2 are shown for each transceiver station 3.1-3.4. The message receivers 5.1 and 5.2 are prepared in charging stations 4.1 to 4.4 for being taken out by the operating operator. The functions and structures of the message receivers 5.1 and 5.2 are the same as those of the above-described embodiment shown in FIG. The number of message receivers assigned to one of the transceiver stations is related to the operator. Therefore, basically, more than two message receivers may be provided for each transceiver station.

To this extent, the function for performing operations on production position of manufacturing Group H ₁ to H ₄ are the same as previous embodiment.

Therefore, the operating device according to the present invention and the method according to the present invention for operating a large number of manufacturing positions are advantageous in that a complex textile mechanical device having a large number of manufacturing positions can be operated as quickly and efficiently as possible. Suitable for being able to operate on. Again, different operation categories can improve operation management.
