Description

Textile machine and maintenance trolley for textile machine
Technical Field
The invention relates to a textile machine having a plurality of stations of the same type for producing bobbins, in particular cross-wound bobbins, each station having a yarn store and at least one maintenance carriage which can be moved along the station.
Background
A number of design solutions for textile machines of the type mentioned in the introduction are known from the prior art. Typically, they have a large number of stations arranged next to one another, on which the yarn is wound to form bobbins, typically cross-wound bobbins. They may be winders or spinning machines. In spinning machines, for example, a yarn is produced from a fed fiber sliver, the yarn, after leaving the spinning unit, passes in the yarn running direction one after the other, i.e., in the yarn transport direction, for example, via an unwinding device and a yarn storage device arranged one behind the other, and the yarn is finally wound into a cross-wound bobbin by means of a yarn winding device. The immediate back-and-forth arrangement of the thread winding device and the thread storage device is not absolutely necessary here, but can also be a further component of the intermediate station. The known spinning machines include, in particular, rotor spinning machines and rotor spinning machines, which are also known from the prior art.
In textile machines, yarn stores are respectively present at the workstations for temporarily storing yarn portions, wherein the term "temporarily storing" means that the yarn loop is placed in the yarn store during transport, for example from a spinning unit to the winding device, so that fluctuations in the winding speed of the winding device and/or the unwinding device and fluctuations in the supply speed of the spinning unit can be compensated, wherein in this case fluctuating yarn store filling states occur.
In contrast to textile machines with workstations which do not have yarn storages, new fault states occur in the workstations with yarn storages, which fault states cannot be eliminated with conventional fault elimination mechanisms, which are for example arranged on the respective workstation or are provided by maintenance trolleys which can be moved along the workstation and can be positioned at the faulty workstation. The novel fault state, for example a yarn break in the yarn store, necessitates a fault elimination by manual intervention of the operator in the absence of a suitable fault elimination mechanism on the service trolley or on the work station.
Disclosure of Invention
In view of this, the invention is based on the task of providing a textile machine with a large number of workstations with yarn stores, in which fault states occurring in connection with the yarn stores can be automatically eliminated.
The invention accomplishes this task by means of a textile machine and by means of a maintenance trolley.
The textile machine according to the invention is characterized in that the maintenance trolley has a disturbance elimination mechanism for automatically eliminating fault states occurring in the yarn storage device and/or being attributed to the yarn storage device.
In the textile machine of the invention, the maintenance trolleys which are movable along and positionable at the individual stations of the textile machine are designed to eliminate such faults occurring at the stations in connection with the use of yarn storages. The special interference situation associated with the yarn store is especially a broken yarn in the yarn store, wherein in this case a fault elimination can occur by means of an interference elimination mechanism on the maintenance trolley of the textile machine according to the invention, in the course of which the reestablishment of the yarn connection is effected, for example, from the spinning position to the winding bobbin, preferably a cross-winding bobbin.
The textile machine according to the invention ensures, in particular, that the fault states associated with the yarn store can be automatically eliminated, so that manual intervention by an operator can be dispensed with. Because of the reduction in manual intervention for error correction, the downtime of the workstation can be significantly reduced. Since the fault state associated with the yarn store occurs only to a small extent, the arrangement of the respective interference suppression means on the maintenance trolley is a particularly economical solution compared to the arrangement of the respective interference suppression means on a separate work station. The maintenance trolley can be temporarily moved to the respective station as required and there reliably eliminates faults occurring in connection with the yarn store.
According to the invention, the maintenance trolley is designed for the error elimination of such disturbances which occur as a result of the use of the yarn store at the work station. Furthermore, the maintenance trolley can also be designed to perform other tasks, such as for example eliminating other disturbances not related to the yarn store or cross-winding bobbin replacement.
The design of the interference suppression means for the error suppression of the yarn store-specific error state is in principle freely selectable. However, according to a particularly advantageous embodiment of the invention, it is provided that the interference elimination device has a clearing device for removing yarn residues from the yarn store. The use of a clearing device ensures in particular that yarn residues or remnants resulting from the movement of the yarn through the yarn store, which could cause disturbances in operation in the yarn store, are removed from the yarn store. The use of the clearing device is thereby carried out within the scope of eliminating interference specific to the yarn store, wherein the clearing device can be designed, for example, to be pneumatically operated and to generate an air flow in the yarn store by means of a positive or negative pressure, whereby dirt is removed.
According to a further embodiment of the invention, it is provided that the interference suppression means have optical inspection means for inspecting the yarn store. The optical inspection means may be designed to identify faults occurring at the workstation, so that appropriate measures for eliminating the faults may be carried out. Alternatively or additionally, the optical checking device can also be used to monitor the error correction and/or to check the error correction performed, wherein, for example, it is checked by means of the optical checking device whether residues remain inside the yarn storage device and/or the yarn course in the yarn storage device after the error correction is checked.
Within the scope of error elimination, it is generally necessary to reconnect the broken thread in order to be able to continue the winding process at the textile machine station. For producing the yarn connections, suitable connecting means can be arranged at a separate station of the winder, for example. However, according to a particularly advantageous embodiment of the invention, it is provided that the service trolley has a yarn splicing device. The arrangement of the yarn splicing device on the service trolley provides a particularly economical yarn splicing solution. In this case, the yarn splicing device can also be present in addition to the yarn splicing device arranged at the work station, wherein the yarn splicing device formed on the service trolley is designed in particular for the reestablishment of the yarn connections after the occurrence of problems specific to the yarn store.
The design of the yarn joining device can be selected in principle. However, according to a particularly advantageous embodiment, it is provided that the splicing device has a gripper nozzle and an actuating device for positioning the free thread end in the region of the splicer, in particular the splicing unit and/or the knotting unit. The corresponding yarn splicing mechanism is designed so that the maintenance trolley is independent of the corresponding device on the station. The yarn splicing device designed according to this development of the invention allows the yarn ends assigned for connection to be taken from the cross-wound bobbin and fed to the splicer after it has been prepared. A correspondingly designed yarn joining device ensures a very reliable operating mode because of the mutually optimum orientation of the individual devices, whereby the downtime can be reduced by a complementary mode.
According to a further embodiment of the invention, the thread splicing device can also be designed to place the free thread end in the threading position of the working position. In the case of a correspondingly designed maintenance trolley, a new yarn end can thus be reliably established by the maintenance trolley without the need to use devices at the working positions, in which it is produced at the position of the working position at which the free yarn end from the crosswound bobbin is connected to the yarn fed from the spinning device.
According to a further embodiment of the invention, it is further provided that the maintenance trolley has a thread checking device, in particular an optically active thread checking device. The thread checking device allows the thread joint to be checked, in particular after the thread joint has been reestablished, and allows work to be carried out at the work station after the checking result is positive. The faulty connection can be detected by the thread checking device and can be eliminated by suitable measures, so that a renewed interference by the faulty connection is avoided.
The invention also provides a maintenance trolley which is characterized in that a disturbance eliminating mechanism is provided for automatically eliminating the fault state occurring in the yarn storage device and/or to be attributed to the yarn storage device. The maintenance trolley can be designed according to one or more of the maintenance trolley improvements described above in relation to the textile machine, whereby the functionality of the maintenance trolley for the textile machine is increased in a complementary manner.

Detailed Description
Fig. 1 shows a textile machine 1 in the form of a spinning machine with a large number of workstations 2 arranged next to one another in a simplified representation. Each workstation 2 of the textile machine comprises a fibre sliver supply 3, which can be designed, for example, in the case of a workstation 2 formed as a spinning station, in the form of a spinning can, a drafting device 4, a spinning device 5, an unwinding roller pair 6, a clearer 7, a yarn laying mechanism 8, a yarn store 17 and a cross-wound bobbin 9 of a winding device. The maintenance trolley 10 is mounted so as to be movable on rails 11, 12 extending along the textile machine 1. A drive unit 13 provided at one end of the textile machine 1 is used to drive the textile machine 1.
In the event of a disturbance at a workstation 2 in the region of the yarn store 17, the maintenance trolley 10 is positioned along the textile machine 1 at the workstation 2 where the disturbance occurred. In the event of a yarn break in the yarn store 17, for example, the maintenance trolley 10 is moved to the relevant station 2, positioned there and, using a disturbance rejection mechanism not shown here, the fault rejection is started. In the event of a thread break in the storage container 17, the maintenance trolley 10 can find the broken thread end falling on the circumferential surface of the cross-wound bobbin 9 by means of the thread holding mouth belonging to the interference elimination mechanism. After the cleaning of the spinning device 5, the thread end is fed back into the area of the spinning device 5 after a corresponding preparation operation by an actuating device, which is known as a disturbance rejection device, and is there ready for the actual thread piecing operation. At the same time, a defined yarn length is unwound by the drive of the cross-wound bobbin 9 and is temporarily stored in the yarn store 17.
