Definitions

  • the invention relates to a method for operating a service unit for processing work orders relating to a cheese / empty tube change and a package spinning spinning machine with at least one movable along the work stations service unit.
  • service units in the application which are designed as piecing.
  • Such piecing are used in open-end spinning machines, the jobs need help both in a "normal" thread break as well as a cheese / empty tube change.
  • service units are also known, which work as a change and cleaning car.
  • Such change and cleaning cars operate open-end spinning machines, which have largely self-sufficient jobs.
  • the jobs of such open-end spinning machines each have next to a spinning device for manufacturing a thread and a winding device for producing a cross-wound further functional elements that allow the jobs to spontaneously back to touch after a thread break.
  • Such jobs need the help of a mobile service unit therefore only if the job is to be cleaned, or if at one of the jobs pending a cross-coil / empty tube change.
  • Such a cheese / empty tube change is usually carried out when at one of the jobs the cheese has reached its prescribed diameter or a predetermined length of thread and must be replaced with a new empty tube.
  • a so-called work order is reported by the workplaces, whereupon the service unit moves to the corresponding workstation and positions itself in front of it.
  • An empty tube is requested and transported via a tube feed path to the service unit or the workstation.
  • the service unit Through the service unit, the full cross-wound bobbin is removed from the bobbin frame of the relevant workstation and transferred to a spinning machine-own cross-bobbin transport device.
  • the service unit also has a gripping device with which the supplied empty tube is removed from the tube feeding path and into the creel can be inserted.
  • the service unit ensures that the open-end spinning device is re-spun by means of a so-called auxiliary thread and the new thread is fixed to the previously inserted into the creel empty tube.
  • the work order is processed by the service unit and the service unit is available for a next work order, such as for processing a next cheese / empty tube change available.
  • the service unit can not carry out a cheese / empty tube change at any other workstation, even if one or more other workstations have reported a work order for this purpose. This results in delays that can lead to undesirably long downtimes of jobs.
  • the DE 199 05 856 A1 discloses an open-end spinning machine having a plurality of work stations between its end frames. These jobs are supplied during operation by several service units. If now at one of the jobs a cross-wound bobbin has reached its prescribed diameter, this is replaced with an empty tube. That is, the service unit drives, for example, notified by the central machine control, to the relevant job and snaps there.
  • the service unit which always carries an empty tube in its own memory, initially takes the finished cross-wound bobbin out of the creel of the relevant workstation and transfers it to the cross-bobbin transport device arranged behind the workstations. Subsequently, the service unit changes the carried empty tube into the creel of the relevant workstation.
  • the service unit also issued a sleeve request. That is, the sleeve delivery device has been commanded to immediately send a sleeve into the area of the work site where the service unit is currently operating.
  • a service unit is requested and positioned at the workstation. From the sleeve magazine, a sleeve is requested, which is transported by means of a tube feed path to the workplace. After the cross-wound bobbin has been removed from the creel, the service unit with the gripping device removes the delivered sleeve from the tube feeding path and subsequently changes it into the creel.
  • a first aspect of the invention therefore relates to a method for operating a service unit for processing work orders relating to a cheese / empty tube change, which is used on spinning reels producing spinning machines that process at least two different lots, wherein in a first step the service unit via a spinner own An empty tube supplied to the tube feeding path and in a second method step, the supplied empty tube is received by the service unit.
  • the method is characterized in that when the current work order for the cheese / empty tube change of the job goes out before this has been processed and the empty tube has been loaded and a next job is present, the cheese / empty tube change to another processing another batch Job concerns, in a third step, the already taken empty tube is dispensed by the service unit, and in a fourth step, the service unit receives an empty tube of another lot to perform a cheese / empty tube change at the next job can.
  • This procedure ensures that the service unit is always available to process work orders, except when processing work orders at a workstation.
  • necessary cheeses / empty tube changes can be performed immediately, since the service unit can not be blocked by an empty tube, which can not replace it.
  • This is particularly eminent in a multi-lot occupancy to minimize unnecessary downtime of the individual jobs that are waiting for a cheese / empty tube change. Not only does this improve the efficiency of each individual service unit, it also optimizes overall machine efficiency.
  • the service unit moves to the relevant workstation and the empty tube required for this batch is removed requested and transported via a Hülsenzu Fightingbahn to the service unit respectively the workplace.
  • the replaceable and usually full cross-wound bobbin is taken from the service frame from the creel and transferred to a spinning machine own cross-spool conveyor, this is done for example with a integrated in the service unit frame opener combined with a discharge and drive arm.
  • the empty tube is removed from the tube transport path and inserted into the creel.
  • the service unit can deliver the already existing in the gripper empty tube, it is immediately in a position to perform a job for a cheese / empty tube change, at another job that another Processed lot and thus requires another empty tube is necessary.
  • the dispensed by the service unit empty tube is placed back on the sleeve feeding path.
  • the existing from the service unit in the gripping device empty tube can be placed back on the sleeve feed path when the current work order and before this empty tube could be replaced at the corresponding work in the creel.
  • the empty tube is then transported away via the tube feed track and the service unit can immediately carry out a new work order with regard to a cheese / empty tube change.
  • the dispensed by the service unit empty tube is placed in a storage device.
  • the empty tube can also be placed in a storage device. It is within the scope of the invention conceivable that this storage device is either inside or outside the service unit. It is essential that the gripping device of the service unit can put the empty tube in the storage device, so that the service unit for a next cheese / empty tube change is ready for use without delay.
  • the set by the service unit in a storage device empty tube is removed again by the service unit in the course of a new job and used for a cheese / empty tube change.
  • the empty tube placed by the service unit in a depositing device is removed manually.
  • the empty tube stored in the storage device is removed manually by an operator, so that the storage device is again available for a new empty tube to be deposited.
  • a second aspect of the invention therefore relates to a package spinning spinning machine having a plurality of workstations and at least one movable along the workstations service unit for processing work orders concerning a cheese / empty tube change at the individual workstations, the service unit via a spinning machine's own tube feed path an empty tube can be fed and the service unit has a gripping device with which the delivered empty tube can be removed from the tube feeding path, and wherein the service unit comprises a control device which is connected to a central control device and in turn connected to the workstation control devices.
  • the spinning bobbin-producing spinning machine is characterized in that the control device or the central control unit is adapted, in the case of the termination of the job for the cheese / empty tube change before this performed by the service unit and the empty tube was switched to control the service unit so that the empty tube taken from the tube feed path can be laid by the service unit into a sleeve receptacle, and then a new empty tube suitable for another lot can be removed from the tube feed path, in order to perform a cross-coil / empty tube change at a further work station processing the other section.
  • the service unit can be controlled demand-oriented. This can be realized even during the cross-coil / empty-tube change cycle, that is, at any time before the empty tube is loaded into the creel, even after, for example, the full cross-wound bobbin has already been removed from the creel.
  • the service unit is controlled so that the removed from the service unit by means of a gripping device from the tube feeding empty tube is dispensed again. It is irrelevant for the invention, as the gripping device of the service unit is structurally designed, whether, for example by gripping elements or pneumatic cylinder, it is essential that the service unit has a device by means of which the empty tube is taken over by the tube feeding path.
  • this service unit can process further or other work orders, in particular work orders relating to a change of reel / empty tube at workstations which process another batch and accordingly one use another empty tube. Unnecessary downtimes of the individual service units as well as the work stations waiting for a cheese / empty tube change are thus reduced. This ultimately has a positive effect on the entire spin machine efficiency.
  • the sleeve receptacle is formed by the tube feeding path or a depositing device for depositing the empty tube.
  • a spinning reel-producing spinning machine 1 is shown, formed in this embodiment as an open-end spinning machine having a plurality of jobs 2, which are each equipped with a spinning device 3 and a winding device 4.
  • the open-end spinning machine also has two identical service units 5.
  • a sliver initially placed in sliver cans 6 is spun into threads, which are wound on the winding devices 4 into cheeses 7.
  • the winding devices 4 are, as in Fig. 2 shown equipped with a coil frame 8 for rotatably supporting an empty tube 9 and a cheese 7 and with a winding drum 10 for rotating these elements.
  • the open-end spinning machine also has a central control unit 11, which is connected via a bus system 12 to the workstation control devices 13. Furthermore, such open-end spinning machines have a cross-coil transport device 14 for disposing finished cross-wound bobbins 7 and an empty tube supply device, which essentially consists of an empty tube magazine 15 and sleeve feed tracks 16.
  • the service unit 5 is on guide rails 17, 18, which are arranged on or on the open-end rotor spinning machine 1, movable.
  • the service unit 5 is in Fig. 2 shown in more detail.
  • the control device 19 of the service unit 5, like the workstation control devices 13 and the central control unit 11, is connected to the bus system 12 of the open-end spinning machine.
  • the service unit 5 has, as in Fig. 2 shown, various handling devices that allow the service unit 5, if necessary, to perform a cheese / empty tube change and thereby provide the spinning device 3 of the relevant job 2 and a piecing available.
  • a service unit 5 has, for example, a so-called (not shown) frame opener and an engageable on the surface of the cheese 7 (also not shown) ejection and drive arm.
  • the service unit 5 also comprises a gripping device 20, which is designed, for example, such that its gripper elements are matched to the outside diameter of the empty tubes 9 conveyed over the tube feed tracks 16 into the region of the work stations.
  • Such a service unit 5 is equipped with a device 21 for cleaning the spinning device 3, an auxiliary thread supply device 22 for providing a piecing thread as well as with a thread applying and thread laying device 23.
  • the service unit 5 may optionally also include a storage device 24. In this storage device 24, the stockpiled in the gripper 20 empty tube 9 for an impending cheese / empty tube change after the expiration of the corresponding task before it could be performed, the no longer required empty tube 9 are stored. If the service unit 5 does not have a corresponding depositing device 24, then an empty tube 9 which is not required can be returned to the female feeding track 16.
  • the service units 5 intervene automatically if there is a need for action at one of the workstations 2 and this is signaled by a work order. Such a job exists when at one of the jobs 2, the cheese 7 is fully wound and must be replaced with an empty tube 9. As soon as the service unit 5 is informed via the bus system 12 of the open-end spinning machine that there is a work order at one of the workstations 2, the service unit 5 runs to the relevant workstation 2.
  • the service unit 5 After the service unit 5 is correctly positioned, it exchanges the cheese 7, which has reached its prescribed diameter, against an empty tube 9. That is, the service unit 5 transferred after opening the creel 8 by means of the ejection and drive arm the finished cross-wound bobbin 7 on the cross-bobbin transport device 14 and then changes by means of the gripping device 20, a new empty tube 9, which was the service unit 5 via a Hülsenzu Glassbahn 16 provided by the empty tube magazine 15, in the creel 8 a.
  • a piecing thread 25 is provided by the auxiliary thread supply device 22 of the service unit 5. Then the piecing yarn 25 is withdrawn by a yarn feeding unit 26 from a supply reel 27 and pneumatically via a pivotally mounted delivery pipe 28 in the area of a in FIG. 2 shown, working own suction nozzle 29 transferred, which sucks the thread end.
  • the delivery pipe 28 transports the piecing thread 25 into the area of a threading and thread laying device 23, which in turn brings the piecing thread 25 into the area of the empty tube 9 held in the reel frame 8 of a work station 2, wherein the free end of the piecing thread 25 of the suction nozzle 29 also is handed over to a (not shown) own work Anspinnorgan that prepares the thread end, as usual.
  • the method shown in FIG. 100 relates to the processing of work orders relating to a package / empty tube change by service units 5 used on spinning machines producing spinning machines.
  • the service unit 5 moves to the corresponding job 2 and in a first step 110, the service unit 5 via a spinning machine-own sleeve feed path 16, an empty tube 9 is supplied. Subsequently, in a second method step 120, the empty tube 9 is received by the service unit 5. Usually, the empty tube 9 is thereby removed from a arranged in the service unit 5 gripping device 20 of the tube feed path 16. If the current work order for which the empty tube 9 is already in the gripping device 20 of the service unit 5 before it could be loaded, and there is a next work order for another job 2, which processes another batch, is in a third Step 130, the already stockpiled by the service unit 5 empty tube 9 delivered.
  • the no longer required empty tube 9 is placed in a sleeve receptacle, that is, either covered on the tube feeding path 16 or stored in a storage device 24.
  • the service unit 5 in a fourth method step 140 accept a work order concerning a cheese / empty tube change for another job 2 and record the corresponding empty tube 9 of the tube feeding path 16, even if the other job 2 processes another batch and thus requires another empty tube 9.
  • the service unit 5 can accept the next work order without unnecessary delay and process subsequent requests from other workstations 2 without delay.
