Description

Method and device for operating a plurality of filament production positions

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

The production and finishing of the synthetic threads takes place in a plurality of production positions which occupy the entire plant. For example, a large number of synthetic threads are thereby produced from a polymer melt at a plurality of production locations in a melt spinning apparatus. In each production position, a group of filaments is spun from a polymer melt in parallel, cooled, oriented and individually wound to form filaments. 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 between the production positions facing one another in each case for the removal of the wound bobbins. Thus, many production locations of this type are built up forming a plurality of doffing galleries.

Textile machinery which is also provided with a plurality of production positions is used in the finishing of the synthetic threads. However, the threads are preferably drawn off from the feed bobbin in an individual manner, for example, are conditioned by texturing and wound to form a bobbin. Textile machine devices are therefore known which have more than 400 production locations within one operator corridor, wherein the textile machine devices are arranged alongside one another to form a plurality of operator corridors.

In this type of thread production position, manual operations are necessary, for which an operator is required. Thus, for example, faults in the production process cannot be completely ruled out, so that undesirable interruptions in the production process, which require rapid intervention and recovery, occur at individual production locations. Furthermore, maintenance work also to be performed by the operator at the production location occurs.

In order to achieve a ideally efficient and fast production position work, a method and a device for operating a plurality of thread production positions are known, for example from DE102017110572a1, wherein a plurality of items of operating information are displayed on a large screen. The large screen is provided in the operator corridor or the doffing corridor, respectively, so that an operator in the operator corridor or the doffing corridor can quickly obtain necessary information items, and thus, look at the respective production positions to perform the operation information items. For example, it is thus possible to display on a large screen that a thread break at a particular production location requires a further splicing at the respective production location. But here the operator has in some cases to walk a great distance to the respective production location in order to be able to carry out the operation information item.

However, systems of the type in which the operator acts directly as a recipient of the operating information item 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, in which 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. But there is a problem here in that multiple operators are busy together at the same time to take care of a fault or maintenance at one of the production locations.

The object of the invention is therefore to improve a generic method for operating a plurality of thread production locations of a melt spinning device and/or a textile machine device and a generic device for operating a plurality of thread production locations of a melt spinning device and/or a textile machine device, in order to ensure that an operating information item is carried out in a targeted and rapid manner as possible.

Another object of the present invention is to provide a method and a device for operating a plurality of production positions of wires, which can be used in particular in large plants with a plurality of production positions.

According to the invention, the invention is achieved by a method having the features of claim 1 and by an apparatus as claimed in claim 11.

Advantageous developments of the invention are defined by the features and combinations of features of the respective dependent claims.

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. Thus a very short distance can 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 being reported at one of the production locations, then one of a plurality of transceiver stations is first determined, which transceiver station is assigned to the group of production locations at which the production location giving the fault is located. The operation information item is then transmitted to the respective transceiver station.

The transceiver station forwards the operation information item directly to at least one of the operator's assigned message receivers. By initiating a receipt by the operator to the message receiver, it is ensured that the operation information item reaches the operator. Thus, rapid intervention may be made to resolve the failure of the production location.

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

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

In order to ensure that the operation information item reaches one of the entire operators, a method variant is preferably carried out in which the operation information item is only 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 the operator's receipt is expected at the transceiver station within the reporting time. Thus, the operator is assigned a response time within which to initiate the response piece.

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

However, a method variant is preferably used in which the operation information item is forwarded to the adjacent transceiver station by the respective transceiver station and is transmitted from there to the associated message receiver of the adjacent transceiver station. Thus, the circle of paging the 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, for example after a thread break, it is also provided that the operator initiates an operational confirmation at the message receiver for the respective transceiver station after successful completion of the executed operational information item. The operation initiated by the control device is then completed and can be directly reported back that it has been performed.

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

The following method variant is particularly advantageous for avoiding any overlapping and interference when forwarding the operation information items, in which case the transceiver stations communicate with the assigned message receiver via in each case one of a plurality of fixed messaging frequencies. 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 operators are required for different operating procedures in the production location, it is further provided that the operating information item contains guidance for one of a plurality of operating categories and that the operator is in each case responsible for one of the operating categories. Thus, the operation information item can already be split up at an early stage according to the operation category and can be transmitted in a targeted manner to the operator responsible for the operation category.

For this purpose, it is particularly advantageous for the message receiver to display only the operating information items relating to the operating 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 that operator.

The device according to the invention for operating a plurality of thread production positions is characterized by a communication network which is simple and not easily disturbed in order to transmit operating information items to an 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 an allocator unit according to an advantageous development. The allocator unit communicates directly with the transceiver station for transmitting the generated message.

In order to enable a local, rapid information transmission without complex navigation devices, the development of the inventive operating device in which the transceiver stations are each assigned to one of a plurality of groups of production locations is particularly advantageous. In view of the selection of the group of production locations and the selection of the number of transceiver stations, corresponding precisely positioned operation information items can be transmitted.

In order to make the message receiver accessible 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. A corresponding association between the message receiver and the transceiver station is thus ensured. Each operator is then tasked with storing the message receiver at the end of the shift in the corresponding charging station. Furthermore, the accumulator of the message receiver can be charged during working hours.

Furthermore, since the radio communication between the transceiver station and the message receiver has different messaging frequencies, any superposition and misleading of the operation information items is precluded in view of this. Thus, no communication between different groups of devices is possible.

In order to allow the message receiver to be operated and processed quickly, the message receiver is embodied with at least one acceptance key and one confirmation key, so that the operator only has to press one key to initiate a receipt or to initiate an operational confirmation.

The development of the inventive operating device in which the message receiver has a logging software for registering the operator allows the message receiver to be personalized. Thus, only those operational information items intended to be received by the message receiver may be displayed by the message receiver.

The inventive method for operating a plurality of thread production locations and the inventive operating device are particularly suitable for large-scale plants of melt spinning plants and textile machine plants in order to carry out operational management at a plurality of production locations.

The method according to the invention for operating a plurality of thread production positions will be described below by means of several embodiments of the operating device according to the invention with reference to the accompanying drawings, in which:

FIG. 1 schematically shows a side view of a first embodiment of a melt spinning apparatus having an operating apparatus according to the present invention;

FIG. 2 schematically illustrates a plan view of the embodiment of FIG. 1;

fig. 3 schematically shows a view of a message receiver of the operating device of fig. 1 and 2;

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

A first exemplary embodiment of a melt spinning device with a plurality of thread production locations with an operating device according to the invention for operating a plurality of production locations is schematically illustrated in a side view and a plan view in fig. 1 and 2.

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

At the low level, a winding device 9 is provided for orienting the freshly spun cooled thread and winding it into bobbins. Melt spinning apparatuses of this type are well known and are described, for example, in the publication DE10355294a 1. In this regard, further description relating to melt spinning apparatus is not provided herein, but reference is made 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 positions are indicated by reference numerals 10.1-10.5. The production positions 10.1-10.5 and subsequent production positions extend along the longitudinal sides of the machine. The number of production locations is divided into groups, wherein a group here comprises, in an exemplary manner, five production locations.

As can be seen from the illustration in fig. 2, the winding apparatuses 9 facing one another form doffing galleries 15 here between the production positions 10.1-10.5 and 10.1 'to 10.5'. The doffing gallery 15 serves to transport the winding bobbins 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 group of production locations is designated by reference number H₁-H₁₀And marking. Each production group H of production locations₁-H₁₀Including a total of five production locations. Here, a plurality of threads are simultaneously spun, cooled, oriented and wound into bobbins in each production position. A modern production position is therefore known in which 32 threads are produced side by side in parallel.

To operate production group H₁-H₁₀Having a plurality of transceiver stations 3.1-3.10. Each transceiver station 3.1-3.10 is assigned to a group of production locations H₁-H₁₀. For example, the production locations 10.1-10.5 are thus allocated to the upper level of the transceiver station 3.1. Five production positions 10.1-10.5 form a production group H₁。

In this connection, production group H of production locations₁-H₁₀Are assigned to transceiver stations 3.1-3.10. The transceiver stations 3.1-3.10 are held in a stationary manner and are connected to the distributor unit 19 via the network 2. The dispenser unit 19 is coupled to the control device 1. Here, the control device1 may be an integral part of a process control unit of the entire melt spinning apparatus. 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 locations 10.1-10.5. The message receiver is implemented in a removable manner and is requested by the operator and carried as a handheld device. For example, the message receivers 5.1 and 5.2 assigned to the transceiver stations 3.1-3.10 can thus be assigned to one charging station 4.1-4.10, respectively. Thus, the operator can retrieve or deposit a message receiver 5.1 or 5.2 at the beginning of the shift and at the end of the shift, respectively. The message receivers 5.1 and 5.2 are charged in charging stations 4.1-4.10, 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 different messaging frequencies. Thus, a defined allocation between the message receivers 5.1 and 5.2 and the transceiver stations 3.1-3.10 is guaranteed.

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. The message receiver is conceived as a receiver device and a sender device for receiving the operation information items and for communicating the information. For this purpose, the message receiver 5.1 has a display 11. An approval key 12, a confirmation key 13, and a menu key 14 are provided below the display 11.

The operator can be acknowledged by the acceptance key 12 as having received the operation information item to the transceiver station. 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 a logging software, with which the operator must register on the device.

In operation, the message receivers 5.1 and 5.2, respectively, are carried with the operator, who is deployed for operation within the melt spinning apparatus. Received at the control device 1 for the production group H₅In the case of an error report of a broken thread at the production location 10.5, 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 relating to the cause of the error.

In order 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 sends the operation information item directly to the transceiver station 3.5 via the network 2. The operation information item is transmitted by means of radio communication 6.5 via the transceiver station 3.5 to one or both of the 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 accept key 12 on the message receiver, whereby the transceiver station 3.5 is informed of the correct delivery of the operation information item. Thus, no further action is initiated and the operator now has to punch immediately to the production location 10.5 to repair the defect in terms of wire breakage and allow the production process to be restarted.

Once the operator has performed the item of operational information and the production process can continue, the confirmation key 13 on the message receiver is activated so that the information can be transmitted to the allocation unit 19 via the transceiver station 3.5 and allocated 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 reporting time has elapsed. The warning signal may be, for example, an audio signal or a visual signal to communicate with a nearby operator or an operator currently at rest.

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

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

The activities required to guide the wire are typically performed by the operator. In order to make it possible for the responsible operator to be ideally contacted when transmitting the operation information item, the latter can be provided with additional comments, for example in the form of a prefix, by means of the distributor unit 19. The comments herein relate to one of a number of operational categories, such as maintenance work, repair, process management, etc., that are performed by specially trained operators. For example, action categories A, B and C may be pre-selected, which are added to the action information item by corresponding letter annotations A, B, C.

In the case of the assignment of this item of operating information to the operating class a, this item of operating information is only present in the message receiver if the latter is carried along by the operator responsible for operating class a. If the corresponding message receiver is responsible for the operation category C, the operation information item transmitted by the transceiver station will not be displayed on the display 11 of the message receiver. It is thus ensured that the operation information item assigned to a specific operation activity and thus to a specific operation category is transmitted in a targeted manner to the responsible operator.

The embodiments of the inventive process apparatus shown in FIGS. 1 and 2 are therefore particularly suitable for operating complex melt spinning apparatus in a rapid and targeted manner. All types of melt spinning equipment may be included herein, regardless of whether the filaments are wound into bobbins, deposited as filament bundles, or chopped into chopped fibers.

Melt production facilities can advantageously be included here, so that malfunctions 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 suitable for complex textile machine installations which require a large number of operating personnel due to the plurality of production positions.

To this end, one embodiment of a textile machine device is schematically shown in the plan view of fig. 4. The textile machine is formed by a creel device 16, a processing device 17 and a winding device 18. The creel device 16, the processing device 17 and the winding device 18 extend here along a doffing gallery 15, which is arranged on the machine-longitudinal side of the winding device 18. The textile machine shown can therefore be a so-called false twist texturing machine, in which a thread is drawn off from a feed bobbin in the creel device 16 at each production position 10.1, oriented and textured in the processing device 17 and wound into bobbins in the winding device 18. Textile machinery of this type is well known and described, for example, in the publication DE102013109530a 1. In this connection, no further explanations are provided here in connection with the textile machinery, 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 group of production locations. These production position groups are designated by the reference number H₁-H₄And marking. The operating device according to the invention is directed to production group H₁-H₄Each having a transceiver station 3.1-3.4. 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. Here, the control device 1 can be connected, for example, to a process controller in order to obtain a plurality of items of information relating to the monitoring and production of the thread in the production location.

A plurality of message receivers is assigned to each transceiver station 3.1-3.4. In this embodiment, too, 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 access 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, it is also possible to provide more than two message receivers per transceiver station.

In this connection, for operating production group H₁-H₄The functional mode of the production site of (a) is the same as in the previous embodiment.

The inventive handling device for handling a plurality of production locations and the inventive method are therefore advantageously suitable for enabling complex textile machine installations with a plurality of production locations to be handled as quickly and efficiently as possible. Here, different operation classes may also improve operation management.
