Definitions
- the invention relates to a method for operating a textile machine producing cross-wound bobbins, which has a large number of self-sufficient workstations, each of which has a spinning device and a winding device and which has a suction nozzle connected to the vacuum network of the textile machine for picking up a thread from the surface of a cross-wound bobbin as well as a storage nozzle, which is also connected to the vacuum network, are equipped for temporarily storing excess thread length, and which is operated by at least one service unit which, if necessary, changes full packages for empty tubes.
- the invention also relates to a textile machine producing cross-wound bobbins.
- Textile machines that produce cross-wound bobbins such as open-end rotor spinning machines or air-jet spinning machines, generally have a large number of similar workstations arranged in a row next to one another, on each of which a thread is spun from a sliver that is presented in a spinning can, for example is then wound into a cheese.
- the workplaces of such textile machines each have a large number of different devices, for example a spinning device and a winding device, and for a long time it has been customary to act on the work organs of the workplaces by machine-length drive means.
- the workplaces of such textile machines are usually served by at least one service unit that patrols along the workplaces of the open-end rotor spinning machine and intervenes automatically when a need for processing, for example as a result of a thread break, has arisen at one of the workplaces.
- the service unit runs to the job in question, locks itself there and searches for the thread end of the torn thread that has accumulated on the cheese after the thread break with a pivotably mounted suction nozzle that can be subjected to negative pressure.
- Open-end rotor spinning machines have therefore already been developed in the past, the work stations of which, as described, for example, in DE 101 39 075 A1, operate largely independently.
- This means that the workplaces of such open-end rotor spinning machines are not only equipped, as usual, with an open-end spinning device and a winding device, but these workplaces also each have a pivotably mounted suction nozzle that can be subjected to negative pressure and a storage nozzle that can also be subjected to negative pressure.
- the pivotably mounted suction nozzle is adjustable by means of an electric motor drive between a yarn end take-up position in the area of the surface of the cheese and a yarn end transfer position in the area of the open-end rotor spinning device, while the stationary storage nozzle temporarily absorbs the excess yarn that occurs during the run-up of the work station.
- the suction nozzle and the storage nozzle are connected via a connection line to a machine-length channel of the vacuum network of the textile machine and can be acted upon by negative pressure together via a valve or a slide.
- Another advantage of such open-end rotor spinning machines equipped with self-sufficient workstations is that after technical problems, e.g. after voltage drops in the power grid, in which all workstations of the textile machine usually come to a standstill at the same time, a plurality of workstations can be spun again at the same time.
- the number of jobs that can be re-spun at the same time is limited to a certain number of jobs due to the storage nozzle that can be subjected to negative pressure and the suction nozzle that can also be subjected to negative pressure, each of which has a relatively high consumption of suction air.
- the suction nozzle and the storage nozzle are connected to the negative pressure network independently of one another via separate connection lines.
- a closure means is switched on in each of the connection lines, which makes it possible to pneumatically connect the suction nozzle or the storage nozzle to the vacuum network or to decouple it from the vacuum network when the relevant organ is no longer needed during the piecing process. That is, the suction nozzles and the storage nozzles, which represent relatively large negative pressure consumers, are purposefully only connected to the negative pressure network of the textile machine for as long as they absolutely need negative pressure.
- Autarkic workplaces which have the embodiment described in DE 10 2006 047 288 A1, have a significantly lower vacuum requirement during a piecing process compared to autarkic workplaces according to DE 101 39 075 A1, with the result that the number of workplaces which, after a technical problem can be spun again at the same time, could be roughly doubled.
- the invention is based on the object of developing a method with which the operation of open-end rotor spinning machines that are equipped with self-sufficient work stations is optimized, in particular the period of time that is necessary to restore all work stations of the textile machine spinning again is minimized. That is to say, the method according to the invention is intended to ensure that after a "Shutdown" of the textile machine ensures that the maximum number of self-sufficient workplaces are always re-spun at the same time.
- this object is achieved in that when re-spinning the autonomous workstations of the textile machine after a technical problem in which all workstations of the textile machine have been switched off, one of the service units prevents a package / empty tube change from being made during the piecing processes, so that it is ensured that when the self-sufficient jobs are re-pinned, the maximum number of jobs is always re-pinned at the same time.
- the method according to the invention has the advantage that the temporary blocking of interventions by the service units prevents additional vacuum consumers from reducing the amount of suction air available in the vacuum network of the textile machine during the piecing processes of the self-sufficient workplaces. This means that it is ensured that during the re-spinning of the workplaces of the open-end rotor spinning machine, the entire amount of suction air available in the vacuum network of the textile machine is always available for the piecing processes of the workplaces and can therefore always be spun with the maximum number of workplaces at the same time.
- the central control unit of the textile machine is preferably prevented from sending work orders to one of the service units.
- Such a temporary waiver of interventions by the service units prevents that during the re-spinning process of, for example, 500 to 600 workplaces of the textile machine, the number of the textile machine is repeatedly re-established again and again connectable self-sufficient jobs decreases. This means that the number of jobs that can be continuously re-spun at the same time is avoided by about two times less than the number of jobs that can be re-spun at the same time if the negative pressure network is not used by additional consumers .
- the object is also achieved by a textile machine which produces cross-wound bobbins and which comprises a control unit for carrying out the method according to the invention.
- the central control unit which is already present is preferably modified for this purpose.
- the central control unit is then preferably designed such that it does not send any work orders to one of the service units during the re-spinning processes of the work stations after a technical problem in which all work stations of the textile machine have been switched off.
- FIG. 1 shows a perspective view of a textile machine producing cross-wound bobbins in which the method according to the invention is used, in the exemplary embodiment an open-end rotor spinning machine with autonomous work stations and two service units that can be used if necessary,
- FIG. 2 shows a perspective view of an autarkic work station of the open-end rotor spinning machine shown in FIG. 1, the work stations each being equipped with a suction nozzle that can be pressurized in a defined manner and a storage nozzle that can also be pressurized in a defined manner.
- FIG. 1 shows a perspective view of a textile machine producing cross-wound bobbins, an open-end rotor spinning machine 1 in the exemplary embodiment are equipped.
- the open-end rotor spinning machine 1 is also equipped with two or more identical service units 5, which change packages 7 that are finished in normal operation for empty tubes 9 and ensure that the work stations 2 are cleaned cyclically.
- the spinning devices 3 of the work stations 2 as is known, a fiber sliver presented in a spinning can 6 is spun into a thread, which is then wound onto one of the winding devices 4 to form a cheese 7.
- the winding devices 4 are each equipped with a bobbin frame 8 for rotatably holding an empty tube 9 or a cross-wound bobbin 7 and with a winding drum 10 for rotating these elements.
- the open-end spinning machine 1 also has a central control unit 11 which is connected to the control devices 19 of the service units 5 and the control devices 13 of the work stations 2 via a bus system 12. Furthermore, such open-end rotor spinning machines 1 have a package transport device 14 for disposing of finished packages 7 and an empty tube supply device, which essentially consists of an empty tube magazine 15 and tube feed tracks 16.
- the service units 5 can be moved on guide rails which are arranged on the open-end rotor spinning machine 1 and, as is known, have various handling devices (not shown) that enable the service units 5 to change or change cheeses / empty tubes if necessary to clean the workplaces 2. That is, during the regular spinning operation, the service units 5 automatically intervene if there is a need for processing at one of the work stations 2 and this is signaled, for example, by a work order. Such a work order exists, for example, when the cheese 7 has reached its specified diameter at one of the work stations 2 and has to be exchanged for an empty tube 9.
- FIG. 2 shows a perspective view of one of the autonomous work stations 2 of an open-end rotor spinning machine 1, in which the method according to the invention is used if necessary.
- such work stations 2 are each equipped with a spinning device 3 and a winding device 4, with a so-called thread take-off tube 21 on the spinning device 3 Spinning member 17 is arranged.
- the piecing element 17 After a thread break or a controlled cleaner cut, the thread 20 retrieved from the cross-wound bobbin 7 by the vacuum nozzle 18 is taken over and the thread end is prepared for re-spinning.
- Such self-sufficient workplaces 2 are each equipped with a thread take-off device 27, which both takes over the removal of the thread 20 from the spinning device 3 during regular spinning operation and ensures the defined return of a prepared thread 20 to the spinning device 3 during re-spinning.
- the winding device 4 has a bobbin frame 8 for rotatably holding a cheese 7, a winding drum 10 that can be acted upon by a reversible individual drive 22, and a thread traversing device 24 that is driven, for example, by means of a stepping motor 26.
- such autarkic work stations 2 each have a pivotably mounted suction nozzle 18 which can be subjected to negative pressure and which can be adjusted in a defined manner by means of a stepping motor 28 between a thread take-up position located in the area of the winding device 4 and a thread transfer position located in the area of the spinning device 3, and via a storage nozzle 25, which can also be pressurized, which temporarily stores the excess thread length that occurs while the workstation 2 is running and ensures that the thread 20 produced in the spinning device 3 is wound onto a package 7 with a correct winding tension.
- Both the storage nozzle 25 and the pivotably mounted suction nozzle 18 are defined and can be acted upon separately with negative pressure.
- the suction nozzle 18 is connected via a connection line 23 and the storage nozzle 25 via a connection line 32 to the textile machine's own vacuum network 30, the vacuum source of which is identified by the reference number 31 in FIG.
- the closure means 29, 33 which via control lines 37 or 38 are connected to the control device 13 of the work station 2 or to the central control unit 11 of the open-end rotor spinning machine 1, ensure that the suction nozzle 18 or storage nozzle 25 is subjected to negative pressure as required or is separated from the negative pressure network 30 of the open-end rotor spinning machine 1.
- the amount of vacuum that can be simultaneously provided by the vacuum network 30 of the open-end rotor spinning machine 1 is relatively limited due to the construction of the vacuum network 30, in particular the cross-section of the machine-length vacuum channel, it is advantageous in this context if, on the one hand, the The suction air requirement of the individual work stations is minimized and, on the other hand, it is ensured that no further, additional suction air consumption is made during the start-up process of the open-end rotor spinning machine 1.
- the present invention has succeeded in reducing the suction air requirement of workplaces 2 to be reduced during the piecing process to such an extent that the number of work stations 2 which can be pieced on again at the same time after a technical problem could be significantly increased.
- the method according to the invention which is used in particular when re-spinning a textile machine 1 producing cross-wound bobbins after a technical problem in which all work stations 2 of the textile machine 1 have come to a standstill, prevents the autarkic work stations from simultaneously piecing together 2 a service unit 5 can be used, which would activate an additional suction air consumer. That is, according to the method according to the invention, it is ensured that the central control unit 11 of the open-end rotor spinning machine 1 does not send a work order to one of the service units 5, even if there is a need at a work station 2. Such work orders are only issued again when all of the, for example, 500 to 600 work stations 2 of the open-end rotor spinning machine 1 have been spun again.
