Definitions

  • the present invention relates to a method for the maintenance of spinning stations of a spinning machine with a plurality of juxtaposed spinning stations and at least one maintenance device which is movable along the spinning stations and by means of which the spinning stations are serviced.
  • a housing of the spinning station is opened before waiting for a spinning station, the spinning station serviced by the maintenance facility and after waiting for the spinning station, the housing closed again.
  • the invention relates to a corresponding spinning machine for carrying out the method.
  • the spinning machine has a plurality of similar jobs, which are each equipped with a spinning device for producing a thread and a winding device for creating a cross-wound bobbin and are designed so that a recovered after a spin interruption of the cheese, prepared for the piecing process and laid in a piecing position Thread end can be spun independently by the spinning device again.
  • time-critical steps of the piecing process such as the defined return of the prepared thread end into the spinning rotor, the exact start of the fiber feed and the exact beginning of the withdrawal of the thread from the open-end spinning device, are realized by workstation-own facilities.
  • Necessary maintenance work before the actual start of the piecing process, such as rotor cleaning, will be carried out by a service unit operating the workstations independently.
  • the service unit is arranged movable along the open-end rotor spinning machine.
  • a disadvantage of such a method is that before the auxiliary work can be performed by the movable service unit, the spinning device must first be opened manually or by the service unit. However, this is time consuming, which leads to performance losses of the spinning machine.
  • the object of the present invention is therefore to shorten the time required for the maintenance of the spinning station in order to increase the efficiency of the spinning machine.
  • the object is achieved by a method for operating a spinning machine having the features of the independent patent claim.
  • a method for the maintenance of spinning stations of a spinning machine is proposed.
  • the spinning machine has a plurality of juxtaposed spinning stations and at least one maintenance device. With the help of the spinning stations, a yarn is spun from a fiber material.
  • the maintenance device can also be moved along the spinning stations to wait for the spinning stations.
  • the maintenance of the spinning stations comprises, in particular, a cleaning of a spinning rotor.
  • a housing of the spinning station is opened before waiting for a spinning station, the spinning station serviced by the maintenance facility and after waiting for the spinning station, the housing closed again.
  • a spinning machine for carrying out the method is proposed, which has a plurality of juxtaposed spinning stations and at least one maintenance device which can be moved along the spinning stations and by means of which the spinning stations can be maintained.
  • Each spinning station has a housing which is closed during the spinning process and which can be opened to service the spinning station.
  • the housing of the spinning station to be serviced is provided by means of a closure means arranged at the spinning station independently opened. Additionally or alternatively, the housing of the spinning station is automatically closed by the closure means after maintenance. As a result, the spinning station no longer has to be opened and / or closed by the maintenance staff or the maintenance device itself. This shortens the time required for maintenance by the service facility so that the service facility can in turn service more spinning stations. Nor does the maintenance facility have to wait until the maintenance personnel open the spinning station to be serviced. This increases the productivity of the spinning machine.
  • a closure means for independently opening the housing prior to maintenance by the maintenance device and / or for self-closing of the housing after maintenance by the maintenance device is arranged accordingly.
  • the closure means is accordingly designed to open and / or close the housing.
  • the maintenance comprises a cleaning of a spin agent, in particular a spinning rotor and / or a thread take-off nozzle.
  • the cleaning of the spin agent is carried out by means of a arranged in the movable maintenance device cleaning device, but advantageously the spinning device or the housing of the spinning station has been previously opened by the spinning unit itself.
  • the maintenance may include other steps, each requiring the opening of a housing.
  • the spinning machine can be designed as a rotor spinning machine, but the invention can also be used on an air-spinning machine.
  • the housing of the spinning station to be serviced is opened before the maintenance device arrives at the spinning station or is positioned in front of it.
  • the maintenance device can start servicing immediately after it has been positioned in front of the relevant spinning station, so that the time spent by the service device on the Spinning place dwells, is further shortened.
  • the maintenance facility can thereby wait more spinning stations in the same time.
  • the spinning machine and / or the spinning station has a control which detects the approach of the maintenance device to the spinning station to be serviced and controls the closure means such that the housing is opened when the maintenance device reaches the spinning station.
  • the approach of the maintenance device to the spinning station to be serviced is preferably detected by means of a control of the spinning machine, and the opening of the housing of the spinning station to be serviced is initiated, so that the housing is opened when the maintenance device is the spinning station has reached.
  • the approach of the maintenance device can be defined for example as a specific distance of the maintenance device from the spinning station, which is detected by means of certain measuring means.
  • the controller may constantly measure the location of the service facility on the spinning machine and the speed at which the service facility travels toward the spinning station to be serviced. From this, the controller can calculate the expected travel time of the maintenance device until it reaches the spinning station to be serviced and cause the opening of the housing of the spinning station to reach the spinning station by the maintenance device in advance. The spinning station can wait here for the maintenance device with the housing open.
  • the controller must be configured appropriately.
  • a time value can be stored in the controller, which indicates how long it takes to open the spinning station. It is thus possible to calculate a position of the approaching maintenance device, upon reaching the opening of the housing is caused. As a result, the opening is just completed when the maintenance facility reaches the spinning station. at still running production at the spinning station to be serviced is thereby produced at the spinning station as long as possible and it is shortened the time in which the spinning station stands still.
  • an environmental region of the spinning station to be serviced is defined and it is detected by means of the control of the spinning machine whether the maintenance device is located in the surrounding area of the spinning station.
  • the opening of the housing is only and only then initiated when the maintenance facility, or in the case of several maintenance facilities one of the maintenance facilities, is located in the surrounding area and thus a speedy passage of the maintenance facility is foreseeable. An unnecessary or premature opening of the housing can be avoided.
  • the spinning station is stopped and the opening of the housing of the spinning station is initiated as soon as the maintenance facility or one of several maintenance facilities in the surrounding area of the spinning station is detected.
  • the control of the spinning machine must be configured in a suitable manner.
  • the time of the last maintenance can also be taken into account and only when it has been a long time ago, the opening of the spinning unit and the subsequent maintenance process, in particular the preventive cleaning of the spinning rotor is initiated when passing the maintenance device.
  • the housing of the spinning station is automatically closed by the closing means of the spinning station.
  • the closing can take place independently of the position of the maintenance device, that is, for example, already at a time when the maintenance device is still positioned in front of the spinning station.
  • the maintenance device continues its travel and the housing of the spinning station is then automatically closed by the closure means of the spinning station and the production is resumed at the spinning station.
  • the maintenance device can thus already approach and wait for the next place of meaning, which further increases the productivity of the spinning machine.
  • the maintenance device still takes over the fast process of closing the spinning station before it continues its journey.
  • the spinning machine can be serviced faster overall, so that the efficiency of the spinning machine increases.
  • the closure means comprises an actuator, in particular a magnetic switch, a pneumatic and / or a hydraulic piston and / or an electric motor, which opens and / or closes the housing.
  • FIG. 1 shows a schematic view of a spinning machine 1 with a plurality of spinning units 2 (wherein for simplicity, only one spinning station 2 is provided with a reference numeral) and a movable maintenance device 3.
  • the maintenance device 3 is arranged on a rail 4 in a traversing 6 movable.
  • the rail 4 extends around the spinning stations 2 as illustrated here, so that the maintenance device 3 can reach the other side of the spinning machine 1 from one side of the spinning machine 1.
  • a cover 5 (shown here by way of example at the spinning station 2) of a housing 8 of the spinning stations 2 is opened for maintenance by a maintenance person or by the maintenance device 3.
  • the cover 5 of the housing 8 of Spinning station 2 is pivotable in a pivoting direction 7, so that the housing 8 of the spinning station 2 can be opened and / or closed.
  • the opening of the cover 5 by the maintenance staff is very time consuming.
  • the opening of the cover 5 by the maintenance device 3 is still quite time consuming, so that the productivity of the spinning machine 1 is reduced.
  • the cover 5 is attached to a housing 8 of the spinning rotor 10 (see FIG. FIG. 2 ) which is opened.
  • the housing 8 of the spinning station 2 is opened for maintenance of the spinning machine 1 independently for maintenance. Additionally or alternatively, the housing 8 of the spinning station 2 is also automatically closed again after the maintenance. The opening and / or closing is carried out by a closure means 9, which in FIG. 2 is shown.
  • FIG. 2 shows a schematic side view of a spinning station 2 with a closure means 9 for opening and / or closing the housing 8 of the spinning station 2.
  • the present spinning station 2 is designed as a spinning station 2 of a rotor spinning machine and has a spinning rotor 10 as a spinning rotor, which is rotatable in the housing 8 is stored.
  • the yarn F produced by the spinning rotor 10 is withdrawn through a yarn withdrawal nozzle 11 and fed to a winding device, not shown here.
  • the maintenance device 3 can wait for the spinning station, in particular clean the spinning rotor 10 of the spinning station 2.
  • the maintenance device 3 can meanwhile complete maintenance work at another spinning station 2 or use the time for the travel to the next spinning station 2 to be serviced. As a result, a total of more spinning stations 2 can be maintained, so that the productivity of the spinning machine 1 increases.
  • the cover 5 of the spinning station 2 can already be opened when it is foreseeable that the maintenance device 3 will drive past the spinning station 2.
  • the spinning machine 1 comprises a controller, not shown here, in which it is deposited that the spinning station 2 has not been maintained for a long time.
  • the controller recognizes that the maintenance device 3 is moving in the direction of the spinning station 2. It can now be a preventive maintenance of the spinning station 2 is initiated, the spinning unit 2 is stopped, the housing 8 of the spinning unit 2 is opened and the spinning unit 2 is waiting with already opened housing 8 on the maintenance device 3. Thereupon, the maintenance device 3 can wait for the spinning station 2 and then proceed directly to the next spinning station 2 to be serviced.
  • the maintenance operation of the maintenance device 3 includes the cleaning of the spinning rotor.
  • the spinning station 2 is first stopped and holds the thread firmly to be able to spind him after the rotor cleaning again. After the rotor has been cleaned, the spinning station 2 closes again automatically and spins the thread F independently again. It is therefore particularly advantageous if the spinning station 2 has its own piecing device. In principle, however, it is likewise possible that the maintenance device 3 also carries out other activities, such as exchanging the spinning rotor or spinning a thread.
  • the opening of the cover 5 can be made so that upon arrival of the maintenance device 3 at the spinning station 2, the opening of the cover 5 of the housing 8 is just completed.
  • the spinning station 2 can thus produce as long as possible.
  • the maintenance device 3 can then start maintenance immediately.
  • a thread break occurs at the spinning station 2
  • the control can order the maintenance device 3 to the spinning station 2, even before the spinning station 2 independently spins on the thread again.
  • a surrounding area of the spinning station 2 for example an area at a distance of up to five spinning stations 2, is defined in advance.
  • the surrounding area can of course also be defined in the form of a maximum permissible time duration for the travel path of the maintenance device 3 to the spinning station 2.
  • the spinning station 2 already opens automatically, so that the maintenance device 3 can immediately take up the maintenance work, in particular the rotor cleaning, after reaching the spinning station 2. If, on the other hand, no maintenance device 3 is present in the surrounding area of the spinning station 2, then the spinning station spins the thread F again by means of its own piecing device without first cleaning the rotor, since otherwise the spinning station would be unproductively stopped for too long.
  • the present invention is not limited to the illustrated and described embodiments.
  • the spinning machine could also be designed as an air spinning machine.
  • Variations within the scope of the claims are also possible as a combination of features, even if they are shown and described in different embodiments.
