Definitions

  • Such a method is known from DE 10 2004 041 051 A1 known.
  • a maintenance unit which has been requested for performing a maintenance operation of a spinning unit of a spinning machine, in the event of a malfunction in the execution of a subtask of maintenance activity, the maintenance device initiates an independent approach to the interrupted by the disturbance to be performed activity successfully terminate or at least restore the maintenance device to a ready for use state.
  • the maintenance unit can take different measures, one of which provides that in case of a malfunction occurring on the maintenance unit itself, the partial task affected by this malfunction will no longer be carried out by the maintenance unit in the future.
  • a disadvantage of this method turns out that the spinning stations the maintenance unit to carry out a Request maintenance regardless of the presence of a malfunction on the service unit. This process is repeated for each request of a spinning station, regardless of whether the requested maintenance of the spinning unit by the maintenance unit is still feasible or not.
  • Object of the present invention is therefore to increase the efficiency in operating the textile machine and the maintenance units.
  • the inventive method has the advantage that existing requirements for the maintenance unit for the maintenance of jobs can be canceled, which are no longer or not completely feasible due to the present malfunction.
  • the maintenance unit can get to the requesting jobs faster whose specific requirement for a maintenance activity allows at least a partial implementation of the maintenance activity.
  • the requesting jobs can modify their request to the maintenance unit to the effect that the maintenance activity is performed at least partially, omitting the subtask concerned by the malfunction on the maintenance unit.
  • requirements for the maintenance unit are maintained, which despite the malfunction can be completely processed.
  • the method according to the invention thus avoids the method of the maintenance unit to a workstation for performing a maintenance operation, which is not feasible in the knowledge of a present malfunction by the maintenance unit.
  • the workstations in the absence of the malfunction, maintain the requirement for the maintenance unit, although the maintenance activity is not feasible.
  • it is the decision as to whether a request to the maintenance unit affected by a malfunction by the workstations makes sense, ie the workstations themselves or a higher-level central control unit of the textile machine, so that production losses due to the futile start-up of workstations are reduced can be.
  • the check of the presence of a malfunction on the maintenance unit can be done automatically by the Maintenance unit to be performed. Only when a malfunction is detected by the maintenance unit itself is a corresponding message sent via the communication system of the textile machine. The data volume to be transmitted by the communication system is thus kept smaller.
  • the check for the presence of a malfunction in the maintenance unit can be carried out by a central control device of the textile machine.
  • the central control device of the textile machine is in communication with all workstations and with the maintenance unit via the communication system so that information about whether a maintenance activity or a partial task of the maintenance activity has been successfully carried out can be forwarded to the central control device for evaluation.
  • the data volume to be transmitted is slightly larger, but the resources of the central control device are used more intensively.
  • the number of immediately consecutive unsuccessful attempts to perform a subtask or a maintenance operation can be added, the exceeding of a predeterminable total number of failed attempts being classified as a malfunction on the maintenance aggregate, while in the meantime successful completion of a task before exceeding the total number of failed task counts is reset to an initial value.
  • the successive failure of the execution of a subtask or the maintenance activity allows the conclusion that the failure is not due to a fault at the respective work site but to a malfunction of the maintenance unit.
  • the result of the count of failed attempts is evaluated either by the maintenance facility itself or by the central control device of the textile machine to inform the jobs about an existing malfunction of the maintenance unit.
  • the workstations or the central control device evaluate whether the relevant maintenance unit is still suitable for performing the task at the workstation and is to be requested.
  • the workstations may modify the requirements made up to the moment of notification of a malfunction that the maintenance unit performs at least the subtasks or maintenance activities as such, which are feasible independently of the present malfunction.
  • the operation of the textile machine is improved so far that the malfunction of the maintenance unit does not have the immediate stoppage of all requesting jobs result, because a single subtask of a maintenance activity is not feasible.
  • requests made by the workplaces up to the time of the detection of a malfunction which include subtasks or maintenance activities which are not feasible by the maintenance unit due to the malfunction, may be canceled. This is particularly advantageous if the subtasks or maintenance activities to be performed are so-called optional tasks or activities whose non-implementation does not mean that the actual production process is prevented or that the quality of the production process is not directly and sustainably influenced.
  • information about the deletion of the requirements of the affected jobs can be sent. This information is used to cause the workstations, regardless of the request to the maintenance unit to resume or continue the manufacturing process, if this allows their operating condition.
  • the affected workstation can be initiated automatically or by a control by the central control device of the textile machine by the workstation sends a suitable request to the maintenance unit, for example, to resolve a break in the threadline by a piecing or splicing.
  • the information about the deletion of the requirements can be forwarded directly from the relevant maintenance unit to the affected jobs via the communication system of the textile machine.
  • the information can be sent indirectly via the central control device.
  • the workstations can send requests to the maintenance unit which comprise a preparatory execution of at least one partial task of a maintenance activity not affected by the malfunction.
  • the maintenance unit For example, if the operation of the rotor cleaning is affected by the malfunction on the maintenance unit of an open-end spinning machine, which preferably takes place during a bobbin change, the maintenance unit would only be requested by a spinning station to perform the bobbin change with the omission of the rotor cleaning.
  • a purely preventive cleaning of the rotor by the spinning stations is no longer required.
  • the maintenance unit can be transferred to a maintenance position.
  • the maintenance position should be chosen so that the maintenance unit for an operator is easy and accessible.
  • the activity for the duration of the maintenance can be taken over by another maintenance unit.
  • This temporary measure reduces the production down time of the textile machine during the period of maintenance work on the malfunctioning maintenance unit by an operator.
  • information about the communication system of the textile machine can be sent to all workstations after a successful elimination of the malfunction. Sending this information will result in the affected jobs being in the workspace of the Maintenance aggregates, which are in turn due to the malfunction of the maintenance unit in turn are at a standstill, can formulate new requirements for the maintenance unit in order to resume the manufacturing process after a maintenance performed maintenance of the unit.
  • the information can be sent indirectly via the central control device.
  • the spinning machine comprises a central control device which is set up to detect a malfunction on a maintenance unit, which prevents the execution of at least one maintenance activity or at least a partial task of maintenance activity, and that affected by the malfunction maintenance unit or the central control device sends information about the communication system of the spinning machine to all spinning stations on the extent of the malfunction.
  • the spinning machine (1) comprises a central control device (17) which is adapted to detect a malfunction on the maintenance unit (5a, 5b, 6a, 6b), the execution of at least one maintenance activity or at least one subtask prevents the maintenance activity, and that the malfunctioning maintenance unit (5A, 5B, 6A, 6B) or the central control device (17) for sending information via the communication system (18, 20) of the spinning machine (1) to all spinning stations (2 ) about the existence of the malfunction are set up, and that the spinning station (2) is set up to evaluate the information on the existence of a malfunction, in order to decide whether an already before the detection of the malfunction on the

  • the winding device 30 is equipped with a coil frame 29 for rotatably supporting a cheese package and with a winding shaft or winding drum 31 for frictionally driving the cheese 28 and the cheese package.
  • Such open-end rotor spinning machines 1 generally also have a cross-coil transport device 32 for the removal of cheeses 28, which have reached their intended diameter.
  • the change of the cheeses 28 is performed by one of the maintenance units 5A, 5B, 6A, 6B, in whose area of responsibility the respective spinning station 2 falls.
  • Step 41 represents a request of the spinning station 2 to the servicing unit 6A responsible for this working area 4A, which is based on the requirement of a cross-coil change or reel sleeve replacement.
  • a rotor cleaning of the spinning device 24 is carried out at the same time to exploit the run-related stoppage of the job 2.
  • a rotor cleaning is also carried out preventively, if, for example, a change in the thread quality is detected. This can be done at the respective spinning station 2 by querying the current CV value.
  • the result of the evaluation of the query causes the spinning station 2, if necessary, to formulate a request for preventive rotor cleaning to the maintenance unit 6A.

If the processing has been carried out successfully, the subsequent request is carried out according to the step 41 of another spinning station 2 by the maintenance unit 6A within the working area 4A. If the request was processed without or only with partial success, in a step 44, a functional test for determining a malfunction on the maintenance unit 6A is performed and evaluated. Step 45 symbolizes the query as to whether a malfunction has been detected in step 44 or not. In the absence of a malfunction, the process branches back to step 41, and a further request for another spinning station 2 within the workstation area 4A is processed.
  • step 46 all spinning stations 2 belonging to the working area 4A of the maintenance unit 6A are directly from the relevant maintenance unit 6A or indirectly from the central control unit 17 of the spinning machine 1 via the presence of a malfunction and their nature and extent informed.
