Description

Method and device for operating a plurality of filament production positions

Technical Field

The present invention relates to a method for operating a plurality of thread production locations of a melt spinning apparatus and/or a textile machinery apparatus and to an apparatus for operating a plurality of thread production locations of a melt spinning apparatus and/or a textile machinery apparatus.

Background

The production and finishing of the synthetic threads takes place in a plurality of production locations which occupy the entire plant room. For example, a large number of synthetic threads are thereby produced from the polymer melt at a plurality of production locations in the melt spinning apparatus. In each production location, a set of filaments is spun in parallel from a polymer melt, cooled, oriented, and individually wound to form filaments. The production positions of this type are arranged next to one another to form the machine longitudinal side, wherein a so-called doffing gallery is provided for feeding the winding bobbins between the production positions facing one another. Thus, the formation of multiple doffing galleries establishes many of these types of production locations.

Textile machinery equipment, which also has a number of production sites, is utilized in finishing the synthetic threads. In this case, however, the thread is preferably drawn off from the feed bobbin by itself, for example by being deformed and wound into a bobbin. Textile machinery apparatuses having more than 400 production locations within one operator corridor are thus known, wherein the textile machinery apparatuses are arranged alongside one another forming a plurality of operator galleries.

In this type of thread production position, manual operations have to be performed, for which an operator is required. Thus, for example, malfunctions in the production process cannot be completely ruled out, and thus undesirable interruptions in the individual production sites occur which require rapid interventions and resumption of the production process. Furthermore, maintenance work also to be performed by the operator at the production location occurs.

In order to achieve a desired efficient and fast production location work, a method and a device for operating a plurality of thread production locations are known, for example from DE102017110572A1, in which a plurality of items of operating information are displayed on a large screen. The large screen is arranged in the operator's corridor or doffing corridor, respectively, so that an operator in said operator's corridor or doffing corridor can quickly obtain the necessary information items, and thus look at the respective production location to perform the operation information items. For example, it can thus be shown on a large screen that a wire break at a particular production location requires a splice at the respective production location. But here the operator has to walk a relatively long distance to the respective production location in some cases in order to be able to perform the operation information item.

However, systems of the type in which the operator acts directly as a recipient of the item of operating information are also known in the prior art. A method and a device for operating a plurality of thread production positions are known, for example, from DE102009022190A1, wherein an operator carries an operating unit which can be used for locating and identifying positions and for receiving operating information items. Thus, a plurality of operators having a plurality of operating devices can be used to take care of malfunctions and maintenance work in the production location. There is a problem in that multiple operators are all busy together at the same time to take care of a malfunction or maintenance at one of the production locations.

Disclosure of Invention

The object of the present invention is therefore to improve a generic method for operating a plurality of thread production locations of a melt spinning apparatus and/or a textile machine apparatus and a generic apparatus for operating a plurality of thread production locations of a melt spinning apparatus and/or a textile machine apparatus, so as to ensure that the operation information items are implemented in a targeted and rapid manner as possible.

It is a further object of the present invention to provide a method and apparatus for operating a plurality of wire production locations, which can be used in particular in large plants having a plurality of production locations.

The invention is characterized in that the operator closest to the respective production location for executing the operation information item always receives the operation information item. A very short distance can thus be achieved. Furthermore, the operation information items can be directly transmitted to the respective operators without delay. For example, in the case of a fault reported at one of the production locations, one of a plurality of transceiver stations is then first determined, which transceiver station is assigned to the production location group at which the faulty production location is located. The operation information items are then transmitted to the respective transceiver stations.

The transceiver station forwards the operation information item directly to at least one of the plurality of assigned message receivers of the operator. By initiating a receipt by the operator to the message receiver, it is ensured that the item of operational information arrives at the operator. Thus, a quick intervention can be made to resolve the failure of the production location.

To this end, the operation information item may contain direct work instructions for resolving malfunctions, checking actions or e.g. maintenance.

For this purpose, the device for operating a plurality of thread production stations has a plurality of transceiver stations which are connected to a control device via a network. Each transceiver station may be coupled to a plurality of message receivers by wireless communication. Thus, a communication network is realized across a plurality of production locations that allows forwarding of operation information items in a fast and targeted manner.

In order to ensure that the item of operating information reaches one of the entire operators, a variant of the method is preferably carried out in which only the item of operating information is transmitted to those message receivers on which the operator has registered. The message receiver is then actively connected in radio communication with a corresponding transceiver station assigned to one of the operators. Thus, it is ensured that the operation information is received by the operator.

In the event that the message receiver assigned to the transceiver station is not activated by the operator, the following method variant is implemented, in which an acknowledgement of the operator is expected at the transceiver station during the reporting time. Thus, the operator is assigned a response time within which to initiate the response piece.

The following method variant is particularly advantageous in the case that no receipt is received after the reporting time has elapsed, where the transceiver station generates a warning signal in the case that the reporting time has elapsed and no receipt has been received. Thus, for example, an operator in the restroom can be alerted to a need for operation at a production location in the area in which the operator is responsible.

However, a variant of the method is preferably used in which the operation information item is forwarded by the respective transceiver station to the adjacent transceiver station and transmitted therefrom to the associated message receiver of the adjacent transceiver station. Thus, the circle of the paging operator can be enlarged so that the operation information item can be quickly implemented.

In order to be able to continue the production process directly after a wire break, for example, it is also provided that the operator initiates an operation confirmation for the respective transceiver station at the message receiver after successful completion of the performed operation information item. Thus, the operation initiated by the control device is completed and can be directly rewarded for having been performed.

Since not all malfunctions, maintenance and other operational tasks can be taken care of by one of the active operators, it is preferable to carry out a method variant in which the operator sends a piece of feedback information to the respective transceiver station via the message receiver in the event that the operational information item is not carried out. Thus, further measures may be enabled to address the failure or for maintenance.

The following method variants are particularly advantageous for avoiding any overlapping and interference in forwarding the operation information item, where the transceiver station communicates with the assigned message receiver via one of a plurality of fixed message transmission frequencies, respectively. Thus, only those items of operating information which are relevant to the set of production locations can be transmitted in a reliable manner without interference.

Since in some cases different operating procedures in the production location require operators of different qualifications, it is further provided that the operation information items contain guidelines for one of a plurality of operation categories and that the operators are respectively responsible for one of the operation categories. Thus, the operation information items can be split at an early stage according to the operation category and can be transmitted to the operator responsible for the operation category in a targeted manner.

For this purpose, it is particularly advantageous for the message receiver to display only the operation information items relating to the operation category of the operator. The respective operation categories may also be recorded simultaneously by an operator registered and logged in at the message receiver, so that the message receiver displays only those operation information items which are suitable for the operator.

The device according to the invention for operating a plurality of thread production locations is characterized by a communication network which is simple and not susceptible to interference in order to transmit the operating information items to the operator.

In order to create the messages required for operation from the process monitoring and the parameters determined therein, the control device is assigned to a distributor unit according to an advantageous development. The distributor unit communicates directly with the transceiver station for transmitting the generated message.

In order to enable local rapid information transfer without complex navigation devices, the following modifications of the inventive operating device are particularly advantageous, in which transceiver stations are each assigned to one of a plurality of production location groups. In view of the selection of the production location group and the selection of the number of transceiver stations, corresponding precisely located items of operating information can be transmitted.

In order to make the message receiver available to the operator, it is also provided that the message receiver assigned to one of the transceiver stations is held in a charging station and can be selectively retrieved from the charging station by the operator. The correspondence between the message receiver and the transceiver station is thus ensured. The task of each operator is then to store the message receiver at the end of the shift in the corresponding charging station. Furthermore, the battery of the message receiver can be charged outside the operating time.

Furthermore, since the radio communication between the transceiver station and the message receiver has different messaging frequencies, any superposition and misdirection of the operation information items is excluded in view of this. Thus, any communication between the devices of the different groups is not possible.

In order to allow the message receiver to be quickly operated and processed, the message receiver is implemented with at least one approval key and one confirmation key so that the operator simply presses one key to initiate a receipt or initiate an operation confirmation.

The improvement of the message receiver of the operating device according to the invention, which has login software for registering the operator, allows the message receiver to be personalized. Thus, only those items of operational information intended to be received by the message receiver may be displayed by the message receiver.

The method according to the invention for operating a plurality of thread production locations and the operating device according to the invention are particularly suitable for large plants of melt spinning and textile machinery equipment in order to carry out the operation management at a plurality of production locations.

fig. 4 schematically shows a plan view of another embodiment of a textile machinery device with an operating device according to the invention.

Detailed Description

In fig. 1 and 2, a first embodiment of a melt spinning apparatus having a plurality of thread production locations is schematically shown in side view and plan view, the melt spinning apparatus having an operating apparatus according to the invention for operating a plurality of production locations.

Fig. 1 schematically illustrates a side view of a melt spinning apparatus extending across multiple levels. Only those equipment required for the production of the synthetic threads are shown in this example. The spinning nozzle device 7 and the cooling device 8 are thus located at a higher position. The spinning nozzle device 7 is connected to a device for producing a polymer melt, which device is not shown in this embodiment.

In the low-height position, a winding device 9 is provided for orienting the freshly spun cooled thread and winding the thread into a bobbin. Melt spinning apparatuses of this type are well known and are described, for example, in publication DE10355294 A1. In this regard, further description is not provided herein with respect to a melt spinning apparatus, but rather with reference to the cited publications.

The spinning nozzle device 7, the cooling device 8 and the winding device 9 have a plurality of production positions. In this embodiment, the first five production locations are identified by reference numerals 10.1-10.5. The production locations 10.1-10.5 and subsequent production locations extend along the machine longitudinal side. The number of production locations is divided into a plurality of groups, wherein a group here comprises, by way of example, five production locations.

As can be seen from the illustration in fig. 2, the winding devices 9 facing each other form a doffing gallery 15 here between the production locations 10.1-10.5 and 10.1 'to 10.5'. The doffing gallery 15 is used to feed the winding bobbins away in the winding device 9.

As can be seen from the illustrations in fig. 1 and 2, the production locations are divided into groups. The production site group is denoted by reference numeral H ₁-H₁₀. Each production group H ₁-H₁₀ of production locations includes five production locations in total. In this case, a plurality of threads are simultaneously spun, cooled, oriented and wound into bobbins in each production location. Modern production locations are therefore known for producing 32 threads side by side in parallel.

In order to operate a plurality of production locations in the production group H ₁-H₁₀, the operating device of the invention has a plurality of transceiver stations 3.1-3.10. Each transceiver station 3.1-3.10 is assigned to a set of production locations H ₁-H₁₀. For example, production locations 10.1-10.5 are thus assigned to the upper level of transceiver stations 3.1. Five production locations 10.1-10.5 form a production group H ₁.

In this regard, a production group H ₁-H₁₀ of production locations is assigned to transceiver stations 3.1-3.10. The transceiver stations 3.1-3.10 are held in a fixed position and are connected to the distributor unit 19 via the network 2. The dispenser unit 19 is coupled to the control device 1. The control device 1 may be a component of a process control unit of the entire melt spinning device. In this connection, the control device 1 has an input and an output in order to be able to receive and transmit information items relating to production monitoring and process production.

As can be taken from the illustrations of fig. 1 and 2, the transceiver stations 3.1-3.10 are each 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 operators who have to perform different operational activities on the production sites 10.1-10.5. The message receiver is implemented in a removable manner and is requested by an operator and carried as a handheld device. For example, the message receivers 5.1 and 5.2 assigned to the transceiver stations 3.1 to 3.10 can thus be assigned to one charging station 4.1 to 4.10, respectively. Thus, the operator can retrieve or store one message receiver 5.1 or 5.2 at the start of the shift and at the end of the shift, respectively. The message receivers 5.1 and 5.2 are charged in charging stations 4.1 to 4.10, respectively.

The message receivers 5.1 and 5.2 are connected to the transceiver stations 3.1-3.10 by radio communication. The radio communications 6.1-6.10 between the transceiver stations 3.1-3.10 and the message receivers 5.1-5.2 each preferably operate at a different messaging frequency. Thus, a defined allocation between the message receivers 5.1 and 5.2 and the transceiver stations 3.1-3.10 is ensured.

For the explanation of the message receivers 5.1 and 5.2, reference is additionally made to fig. 3. Fig. 3 schematically shows a view of an embodiment of the message receiver 5.1. The message receiver 5.1 is implemented in the form of a handheld device and may be based on an operating system with android technology. A message receiver is conceived as a receiver device and a transmitter device for receiving an item of operational information and for communicating information. For this purpose, the message receiver 5.1 has a display 11. Below the display 11 are provided an approval key 12, a confirmation key 13 and a menu key 14.

The operator may be authorized to receive the operation information item from the transceiver station via the approval key 12. The confirmation key 13 allows quick operation confirmation once the operator has successfully performed the activity requested by the operation information item. The menu key 14 allows further transmission functions, for example, to transmit feedback information to the responsible transceiver station if the operation information item has not been executed. Furthermore, the message receiver 5.1 has login software, by means of which the operator has to register on the device.

During operation, the message receivers 5.1 and 5.2 are carried with an operator, respectively, who is deployed for operation within the melt spinning apparatus. In the event that the control device 1 receives an error report for the presence of a wire break at the production location 10.5 of the production group H ₅, an item of operating information is first established by the distributor unit 19 and the respective transceiver station is determined. In this case the transceiver station 3.5 is responsible for transmitting the operation information item concerning the cause of the error.

To generate this item of operating information, the distributor unit 19 can have a plurality of software modules which determine the required operating measures from the process monitoring parameters.

The distributor unit 19 directly transmits the operation information item to the transceiver station 3.5 via the network 2. The operation information item is transmitted by means of radio communication 6.5 via transceiver station 3.5 to one or both of message receivers 5.1 and 5.2. Only the message receivers 5.1 and 5.2 carried by the operator receive this operation information item.

The operator requesting and retrieving the operation information item will now activate the approval key 12 on the message receiver, so that the transceiver station 3.5 is informed about the correct transfer of the operation information item. Thus, no further action is initiated and the operator now has to immediately rush to the production location 10.5 to repair the defect in terms of wire breakage and allow restarting the production process.

Once the operator has performed the item of operational information and the production process can continue, the acknowledgement key 13 on the message receiver is activated so that the information can be transferred via the transceiver station 3.5 to the dispenser unit 19 and dispensed to the control device 1 by means of the latter. Now, the fault is eliminated.

In case neither of the message receivers 5.1 and 5.2 is activated by the operator, the transceiver station 3.5 will generate a warning signal as soon as, for example, 1 minute of reporting time has elapsed. The warning signal may be, for example, an audible signal or a visual signal, in order to contact a nearby operator or an operator currently resting.

But immediately forwards the operation information item in parallel to the adjacent transceiver station, in this case transceiver station 3.6, so that transceiver station 3.6 can send the operation information item to the associated message receivers 5.1 and 5.2. In this case a nearby operator is included to cope with the fault at the production location 10.5 as soon as possible.

Operators of various qualifications are deployed in melt spinning apparatuses of this type because of various operational activities. It is therefore common, for example, for the spinning nozzles used for extruding filaments in the spinning nozzle arrangement 7 to be cleaned regularly on the underside of the spinning nozzle. Such scraping is performed by maintenance personnel.

The activities required for guiding the wire are typically performed by an operator. In order to allow the responsible operator to be optimally contacted when transmitting the operation information item, the operation information item can be provided with additional notes, for example in the form of prefixes, by way of the distributor unit 19. The comments herein relate to one of a plurality of operational categories, such as maintenance work, repair, process management, etc., which are performed by specially trained operators. For example, the operation categories A, B and C may be pre-selected, which are added to the operation information item by the corresponding letter notes A, B, C.

In the case of the operation information item now assigned to operation class a, this operation information item will only appear in the message receiver if it is carried around by the operator responsible for operation class a. If the corresponding message receiver is responsible for operating class C, this item of operational information sent by the transceiver station will not be displayed on the display 11 of the message receiver. It is thus ensured that the item of operating information assigned to a particular operating activity and thus to a particular operating class is transmitted in a targeted and defined manner to the responsible operator.

The embodiment of the operating device according to the invention shown in fig. 1 and 2 is therefore particularly suitable for operating complex melt spinning devices in a rapid and targeted manner. All types of melt spinning apparatus can be incorporated herein, regardless of whether the filaments are wound into bobbins, deposited as bundles of filaments, or cut into chopped fibers.

Melt production facilities can advantageously be included here, so that faults in, for example, polycondensation can be quickly intercepted.

In principle, the inventive operating device and the inventive method for operating a plurality of thread production positions are also applicable to complex textile machinery devices which require a number of operators due to the plurality of production positions.

For this purpose, an embodiment of a textile machine is schematically shown in the plan view of fig. 4. The textile machinery is formed by a creel arrangement 16, a processing device 17 and a winding device 18. The creel arrangement 16, the processing device 17 and the winding device 18 here extend along a doffing corridor 15, which is arranged on the machine-longitudinal side of the winding device 18. The textile machinery shown can thus be a so-called false twist texturing machine, in which a thread is drawn from a yarn supply bobbin in the creel device 16 at each production location 10.1, oriented and textured in the processing device 17 and wound into a bobbin in the winding device 18. Textile machinery devices of this type are well known and are described, for example, in the publication DE102013109530 A1. In this connection, no further explanation is provided here in connection with a textile machine device, but reference is made to the cited publications.

In the embodiment shown in fig. 4, the first twelve production locations 10.1-10.12 each form a set of production locations. These sets of production locations are identified by reference numeral H ₁-H₄. The operating device according to the invention has one transceiver station 3.1-3.4 for each of the production groups H ₁-H₄. The transceiver stations 3.1-3.4 are connected via the network 2 to a distributor unit 19, which is connected to the control device 1. The control device 1 can be connected here, for example, to a process controller in order to obtain a plurality of items of information relating to the monitoring and production of the threads in the production location.

A plurality of message receivers are assigned to each transceiver station 3.1-3.4. In this embodiment, only two message receivers 5.1 and 5.2 per transceiver station 3.1-3.4 are shown. The message receivers 5.1 and 5.2 remain ready for the operator to obtain in the charging stations 4.1-4.4. The message receivers 5.1 and 5.2 are identical in terms of their function and construction to the above-described embodiment according to fig. 3. The number of message receivers assigned to one of the transceiver stations depends on the operator. In principle, each transceiver station may also be provided with more than two message receivers.

In this regard, the functional mode for operating the production location of the production group H ₁-H₄ is the same as the previous embodiment.

The inventive operating device and the inventive method for operating a plurality of production locations are therefore advantageously suitable for being able to operate complex textile machinery devices having a plurality of production locations as quickly and efficiently as possible. Here, different operation categories may also improve operation management.
