Definitions

  • the present invention relates to a method for maintaining spinning positions of a spinning machine with a plurality of spinning positions arranged next to one another and with at least one maintenance device which can be moved along the spinning positions and by means of which the spinning positions are serviced.
  • one housing of the spinning station is opened, the spinning station is serviced by the maintenance device and, after the spinning station has been serviced, the housing is closed again.
  • the invention also relates to a corresponding spinning machine for carrying out the method.
  • a semi-automatic spinning machine is known. In this machine, some maintenance work or preparatory work for it is carried out automatically by means arranged at the spinning station itself. Other maintenance activities or preparatory actions, however, are carried out by operating personnel.
  • the machine of the DE 10 2016 109 216 A1 does not have a movable maintenance facility.
  • the means of the work station include means for at least partially opening the spin box. However, the actual maintenance activities such as cleaning the spinning rotor or initiating piecing are carried out by maintenance personnel.
  • the U.S. 3,879,926 A also describes a spinning machine in which the housing of the spinning device can be opened independently, ie without the aid of an operator.
  • the actual maintenance activities such as cleaning the spinning rotor or piecing can be carried out by maintenance personnel or by means arranged at each individual spinning station.
  • the spinning machine has a large number of similar work stations, each equipped with a spinning device for the production of a thread and a winding device for creating a cheese and designed so that after a spinning interruption from the cheese, which is retrieved, prepared for the piecing process and placed in a piecing position Thread end can be spun again independently by the spinning device.
  • Time-critical steps in the piecing process such as the defined return of the prepared thread end to the spinning rotor, the exact start of the fiber feed and the exact start of the withdrawal of the thread from the open-end spinning device, are implemented by the workstation's 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 that independently operates the work stations.
  • the service unit is arranged to be movable along the open-end rotor spinning machine.
  • a disadvantage of such a method is that before the auxiliary work can be carried out by the movable service unit, the spinning device first has to be opened manually or by the service unit. However, this is time-consuming, which leads to a loss in performance of the spinning machine.
  • the object of the present invention is therefore to shorten the time required for 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 with the features of the independent claim.
  • a method for maintaining spinning positions in a spinning machine is proposed.
  • the spinning machine has a large number of spinning stations arranged next to one another and at least one maintenance device. With the help of the spinning positions, a yarn is spun from a fiber material.
  • the maintenance device can also be moved along the spinning stations in order to service the spinning stations.
  • the maintenance of the spinning positions includes, in particular, cleaning of a spinning rotor. In this case, before a spinning station is serviced, one housing of the spinning station is opened, the spinning station is serviced by the maintenance device and, after the spinning station has been serviced, the housing is closed again.
  • a spinning machine for carrying out the method, which has a plurality of spinning stations arranged next to one another and at least one maintenance device which can be moved along the spinning stations and by means of which the spinning stations can be serviced.
  • Each spinning station has a housing which is closed during the spinning process and which can be opened for servicing the spinning station.
  • the housing of the spinning station to be serviced is automatically opened for maintenance with the aid of a closure means arranged at the spinning station. Additionally or alternatively, the housing of the spinning station is automatically closed by the closure means after maintenance.
  • the closure means has an actuator which opens and / or closes the housing.
  • a closure means for automatically opening the housing prior to maintenance by the maintenance device and / or arranged to automatically close the housing after maintenance by the maintenance device.
  • the closure means is accordingly designed to open and / or close the housing.
  • the closure means has an actuator which opens and / or closes the housing.
  • the maintenance includes cleaning a spinning means, in particular a spinning rotor and / or a thread take-off nozzle.
  • the spinning agent is cleaned by means of a cleaning device arranged in the movable maintenance device, but advantageously the spinning device or the housing of the spinning station has already been opened beforehand by the spinning station itself.
  • the maintenance can also include other steps, each of which requires 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-jet spinning machine.
  • the housing of the spinning station to be serviced is opened before the maintenance device has reached the spinning station or is positioned in front of it.
  • the maintenance device can begin with the maintenance immediately after it has been positioned in front of the spinning station in question, so that the time that the maintenance device stays at the spinning station is shortened even further.
  • the maintenance device can service more spinning positions 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 in such a way that the housing is open when the maintenance device reaches the spinning station.
  • the approach of the maintenance device to the spinning position to be serviced is preferably recognized with the aid of a control of the spinning machine
  • the housing of the spinning station to be serviced is initiated so that the housing is opened when the maintenance device has reached the spinning station.
  • the approach of the maintenance device can be defined, for example, as a certain distance of the maintenance device from the spinning station, which is recorded by means of certain measuring means.
  • the control can, for example, constantly measure the location of the maintenance device on the spinning machine and the speed at which the maintenance device moves in the direction of the spinning station to be maintained. From this, the control can calculate the expected travel time of the maintenance device until it reaches the spinning station to be serviced and cause the maintenance device to open the housing of the spinning station in advance of reaching the spinning station.
  • the spinning station can wait for the maintenance device with the housing open.
  • the control must be configured in a suitable manner.
  • a time value can be stored in the control which indicates how long it takes to open the spinning position. It is thus possible to calculate a position of the approaching maintenance facility which, when it is reached, causes the housing to be opened. As a result, the opening is just completed when the maintenance device reaches the spinning station. While production is still running at the spinning station to be serviced, production is carried out at the spinning station for as long as possible and the time in which the spinning station is stationary is shortened.
  • an area around the spinning station to be serviced is defined and, with the aid of the control of the spinning machine, it is detected whether the maintenance device is located in the area around the spinning station.
  • the opening of the housing is only initiated when the maintenance device, or in the case of several maintenance devices, one of the maintenance devices, is in the surrounding area and it is therefore foreseeable that the maintenance facility will soon pass. Unnecessary or premature opening of the housing can thus be avoided.
  • the spinning station is stopped and the housing of the spinning station is opened as soon as the maintenance device or one of several maintenance devices is detected in the vicinity of the spinning station.
  • 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 if it was a long time ago, the opening of the spinning position and the subsequent maintenance process, in particular the preventive cleaning of the spinning rotor, are initiated when the maintenance facility is passed.
  • a check is made as to whether the maintenance device is located in the surrounding area.
  • the check can also be carried out by means of the control of the spinning machine. If the maintenance device is located in the vicinity of this spinning station, it is ordered to the relevant spinning station for maintenance, the maintenance is carried out and only then is production resumed, in particular a thread is spun again.
  • This embodiment is therefore particularly advantageous in a spinning machine which has its own piecing device. If, after an interruption in production, a maintenance facility is available nearby, ie with a short travel distance, maintenance, in particular cleaning of the spinning rotor in the case of a rotor spinning machine, can be carried out in a very short time before production is resumed. If, on the other hand, there is no maintenance facility in the vicinity, production starts immediately and without Maintenance resumed in order to keep the downtime of the spinning unit as short as possible.
  • the housing of the spinning station is automatically closed by the closure means of the spinning station.
  • the closing can take place independently of the position of the maintenance device, that is to say for example already at a point in time at which the maintenance device is still positioned in front of the spinning station.
  • the maintenance device continues its journey and the housing of the spinning station is only then closed automatically by the locking means of the spinning station and production at the spinning station is resumed.
  • the maintenance device can therefore already move to the next point of meaning and wait, which further increases the productivity of the spinning machine.
  • the maintenance device it is also possible for the maintenance device to take over the fast process of closing the spinning station before it starts moving on.
  • the re-spinning of a thread after the automatic closing of the housing is carried out by a spinning station's own piecing device.
  • the spinning machine can be serviced more quickly overall, so that the efficiency of the spinning machine increases.
  • the closure means comprises, as an actuator, a magnetic switch, a pneumatic and / or a hydraulic piston and / or an electric motor which opens and / or closes the housing.
  • Figure 1 shows a schematic view of a spinning machine 1 with a plurality of spinning stations 2 (for the sake of simplicity only one spinning station 2 is provided with a reference number) and a movable maintenance device 3.
  • the maintenance device 3 is arranged on a rail 4 so that it can be moved in a direction of travel 6.
  • the rail 4 preferably extends around the spinning stations 2, as shown here, so that the maintenance device 3 can move from one side of the spinning machine 1 to the other 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 maintenance personnel or by the maintenance device 3.
  • the cover 5 of the housing 8 of the spinning station 2 can be pivoted 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 personnel is very time-consuming.
  • the opening of the cover 5 by the maintenance device 3 is also 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. Figure 2 ) that is opened.
  • the housing 8 of the spinning station 2 is automatically opened for maintenance in order to maintain the spinning machine 1. Additionally or alternatively, the housing 8 of the spinning station 2 is also automatically closed again after the maintenance. The opening and / or the closing is carried out by a closure means 9, which is shown in FIG Figure 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 element, which rotates in the housing 8 is stored.
  • the thread F produced by the spinning rotor 10 is drawn off by a thread draw-off nozzle 11 and fed to a winding device (not shown here).
  • the cover 5 for closing the housing 8 can also be seen.
  • the opening and closing of the housing 8 takes place by means of the closing means 9, which in the present case comprises a threaded spindle with a drive motor and swings the cover away from the housing 8 or pulls it towards it.
  • the maintenance device 3 can service the spinning station, in particular clean the spinning rotor 10 of the spinning station 2.
  • the maintenance device 3 can conclude maintenance work on another spinning station 2 or use the time to travel to the next spinning station 2 to be serviced. As a result, a total of more spinning stations 2 can be serviced, so that the productivity of the spinning machine 1 increases.
  • the cover 5 of the spinning station 2 can advantageously 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 Control, not shown here, in which it is stored that the spinning station 2 has not been serviced for a long time.
  • the control recognizes that the maintenance device 3 is moving in the direction of the spinning station 2.

  • the maintenance device 3 can then wait for the spinning station 2 and then immediately move on to the next spinning station 2 to be serviced.
  • the maintenance activity of the maintenance device 3 preferably includes cleaning the spinning rotor.
  • the spinning station 2 is initially stopped and holds the thread so that it can be spun again after the rotor has been cleaned. After the rotor has been cleaned, the spinning station 2 closes again automatically and spins the thread F again automatically. It is therefore particularly advantageous if the spinning station 2 has its own piecing device. In principle, however, it is also possible for the maintenance device 3 to also carry out other activities, such as, for example, replacing the spinning rotor or spinning a thread.
  • the opening of the cover 5 can be initiated in such a way that the opening of the cover 5 of the housing 8 has just been completed when the maintenance device 3 arrives at the spinning station 2.
  • the spinning station 2 can thus continue to produce as long as possible.
  • the maintenance facility 3 can then begin maintenance immediately.
  • the control can order the maintenance device 3 to the spinning station 2 even before the spinning station 2 independently spins the thread again.
  • An area surrounding the spinning station 2 for example an area at a distance of up to five spinning stations 2, is advantageously defined in advance.
  • the surrounding area can of course also be in the form of a maximum permissible period of time can be defined for the travel route from the maintenance facility 3 to the spinning station 2.
  • it is then first checked by means of the control of the spinning machine 1 whether a maintenance device 3 is located in the vicinity of the spinning station 2. If this is the case, the spinning station 2 already opens automatically, so that the maintenance device 3 can start the maintenance work, in particular the rotor cleaning, immediately after reaching the spinning station 2. If, on the other hand, there is no maintenance device 3 in the vicinity of the spinning station 2, the spinning station spins the thread F again using its own piecing device without cleaning the rotor beforehand, since the spinning station would otherwise be idle for too long in an unproductive manner.
  • the present invention is not limited to the illustrated and described exemplary embodiments.
