Definitions

  • the invention relates to a textile machine with a large number of similar bobbins, in particular cross-wound bobbin producing workstations, each of which has a thread store and at least one service trolley that can be moved along the workstation.
  • Textile machines of the type mentioned at the beginning are known in various designs from the prior art. These usually have a large number of work stations arranged adjacent to one another, at which a thread is wound onto a spool, usually a cross-wound bobbin. These can be winding or spinning machines. On a spinning machine, for example, a thread is produced from a fiber structure, which after leaving the spinning unit - viewed in the direction of the thread path - one after the other, i.e. H. in the transport direction of the thread, for example the take-off device arranged one behind the other and the thread storage, happens before the thread is finally wound onto a cross-wound bobbin using a thread winding device. A direct successive arrangement of the thread winding device and thread storage is not necessarily necessary, but other components of the workstation can also be interposed.
  • Known spinning machines include, in particular, air-jet spinning and rotor spinning machines, which are also fundamentally known from the prior art.
  • the thread stores present at the work stations are used to temporarily store a thread section
  • temporary storage being understood to mean the arrangement of a thread loop during transport, for example starting from a spinning unit to the winding device within the thread store, so that fluctuations in the winding speed the winding device and/or a take-off device as well as fluctuations in the delivery speed of the spinning unit can be compensated for, which results in a fluctuating fill level of the thread store.
  • the EP 2 361 867 A1 discloses workstations of an air-jet spinning machine with a thread storage device which is suitable for temporarily storing the thread to be wound up by a winding device.
  • the thread storage device includes a thread detection sensor that can detect the thread on the surface of a thread storage roll.
  • the air-jet spinning machine includes a service unit for producing a thread connection after a cleaner cut.
  • the air-jet spinning machine also includes a Fluid blowing device that blows a fluid onto the surface of the thread storage roll after the cleaner cut. According to such a configuration, even if a thread portion remains at a position distant from a thread detection position of the thread detection sensor, it can be moved to the thread detection position of the thread detection sensor by the flow of the fluid blown from the fluid blowing device. Alternatively, the thread section remaining on the surface of the thread storage roll can be removed by blowing the fluid onto the surface of the thread storage roll through the fluid blowing device.
  • the fluid blowing device can be arranged on the service unit.
  • the EP 3 566 987 A1 discloses an air-jet spinning machine with a service unit for producing a thread connection after a thread break. At the workstations there is also a thread storage device with a thread storage roll, as well as a device for removing a remaining thread from the thread storage roll after a thread break.
  • novel error conditions occur in workstations with thread storage that are not provided with conventional error correction devices, which are arranged, for example, at the respective workstations or by the service trolley that can be moved along the workstations and positioned at the faulty workstations can be remedied.
  • the novel error conditions include, for example, the breaking of the thread within the thread storage, which, in the absence of a suitable troubleshooting device on the service vehicle or the workstation, makes it necessary to correct the error through manual intervention by the operating personnel.
  • the invention is based on the object of providing a textile machine with a large number of workstations having thread storage, in which error conditions occurring in connection with the thread storage can be remedied automatically.
  • the invention solves the problem by means of a textile machine with the features of claim 1 and by a service trolley with the features of claim 7.
  • Advantageous developments of the textile machine are specified in the dependent claims 2 to 6.
  • the service trolley has a troubleshooting device for automatically eliminating problems occurring in the thread storage and/or has error states to be assigned to the thread storage, which have an optical inspection device for checking the thread storage.
  • the service trolley which can be moved along the individual workstations of the textile machine and positioned at the individual workstations, is designed to correct errors that occur in connection with the use of the thread storage at the workstations.
  • the specific malfunctions in connection with the thread storage include, in particular, a thread break within the thread storage, in which case the troubleshooting means on the service trolley of the textile machine according to the invention can be used to correct the error, in the course of which the connection of the thread is restored, starting, for example, from the spinning point to to the package, preferably the cheese, is produced.
  • the textile machine according to the invention particularly ensures that error conditions in connection with the thread storage can be remedied automatically, so that manual intervention by the operating personnel can be dispensed with.
  • downtimes at work stations can be significantly reduced.
  • the arrangement of the corresponding interference suppression means on a service vehicle represents a particularly economical solution compared to the arrangement of corresponding interference suppression devices at the individual workstations. If necessary, the service vehicle can drive to the respective workstation at short notice and there Reliably fix the error that occurs in connection with the thread storage.
  • the service trolley is designed to troubleshoot malfunctions that result from the use of the thread storage at the workstations.
  • the service trolley can also be designed to carry out further work, such as correcting other faults that are not related to the thread storage or replacing the cross-wound bobbins.
  • the interference suppression means for troubleshooting thread storage-specific fault states is fundamentally freely selectable. According to a particularly advantageous embodiment of the invention, however, it is provided that the interference suppression means have a cleaning unit for removing thread residues from the thread storage.
  • the use of a cleaning unit particularly ensures that thread residues are removed or residues as a result of the thread running through the thread store are removed from the thread store, where these can lead to malfunctions during operation.
  • the cleaning unit is used in the context of rectifying a thread storage-specific fault, whereby the cleaning unit can, for example, be designed to act pneumatically and an air flow is generated within the thread storage by means of positive or negative pressure, through which contaminants are removed.
  • the optical inspection device for checking the thread storage can be designed to identify the error occurring at the work site so that suitable measures can be taken to correct the error.
  • the optical inspection device can also be used to monitor the troubleshooting and/or to check the troubleshooting that has been carried out, for example using the optical inspection device to check the interior of the thread storage for remaining residues and/or the thread run within the thread storage is checked after the troubleshooting .
  • the service trolley has a thread connecting device.
  • the arrangement of a thread connecting device on the service trolley represents a particularly economical solution for thread connecting.
  • the thread connecting device can also be present in addition to the thread connecting devices arranged at the work stations, with the thread connecting device designed on the service trolley being designed in particular to restore a thread connection after the occurrence of a thread storage-specific problem is.
  • the thread connecting device has a thread search nozzle and manipulation means for positioning the free thread end drawn off from the cheese in the area of a thread connector, in particular a splice and / or knotting unit.
  • the appropriate design of the thread connecting device makes the service car independent of the corresponding units at the workstations.
  • the Thread connecting device designed according to the invention makes it completely possible to remove the thread end intended for connection from the cheese and to feed it to the thread connector after preparation.
  • An appropriately designed thread connecting device ensures particularly reliable functionality due to the optimal alignment of the individual units to one another, which means that downtimes can be reduced in a complementary manner.
  • the thread connecting device can also be designed to arrange the free thread end at a piecing point of the workstation.
  • a new thread connection can be made in a reliable manner without resorting to units at the workstation, this being made at the spinning point of the workstation, where the free thread end coming from the cross-wound bobbin is connected to that from the spinning device supplied thread is connected.
  • the service trolley has thread inspection means, in particular optically acting thread inspection means.
  • the thread inspection means make it possible, especially after the thread connection has been restored, to check it and, after a positive test, to enable operation at the work site. Faulty connections can be detected using the thread inspection means and remedied using suitable measures, so that further disruptions due to the faulty connection are avoided.
  • the invention further solves the problem by a service trolley with the features of claim 7, which is characterized in that it is designed with a troubleshooting means for automatically eliminating error states that occur in the thread store and/or can be assigned to the thread store.
  • the interference suppression means have an optical inspection device for checking the thread storage.
  • the service trolley can be designed according to one or more developments of the service trolley shown above for the textile machine, whereby the functionality of the service trolley for the textile machine is increased in a complementary manner.
  • FIG 1 a textile machine 1 designed as a spinning machine and having a large number of workstations 2 arranged next to one another is shown in a simplified representation.
  • Each work station 2 of the textile machine 1 comprises a sliver source 3, which can be designed as a spinning can, for example in a work station 2 designed as a spinning station, a drafting system 4, a spinning device 5, a pair of take-off rollers 6, a yarn cleaner 7, a thread laying device 8, a thread store 17 and a cheese 9 of a winding device.
  • a service trolley 10 is movably mounted on rails 11, 12 running along the textile machine 1.
  • a drive unit 13 arranged at one end of the textile machine 1 is used to drive the textile machine 1.
  • the service trolley 10 In the event of a malfunction at a workstation 2 in the area of the thread storage 17, the service trolley 10 is positioned along the textile machine 1 at the workstation 2 having the malfunction. In the event of a thread break, for example within the thread storage 17, the service trolley 10 is moved to the relevant workstation 2, positions itself there and begins troubleshooting using the troubleshooting means not shown here. In the event of a thread break within the thread store 17, the service trolley 10 can find the torn thread end lying on the peripheral surface of the cross-wound bobbin 9 via a thread search nozzle, which is one of the fault means.
  • this thread end is, as usual, transported back into the area of the spinning device 5 by known handling devices that are part of the interference suppression means, after appropriate preparation, and kept there ready for the actual spinning process.
