Definitions

  • the invention relates to a method for supplying the spinning positions of an automatic spinning machine with sliver of a certain batch, the sliver cans being changed as a function of the spun amount of sliver, and a device for carrying out the method.
  • DE 25 21 851 A1 discloses a method and a device for changing the sliver containers on a spinning machine. All sliver containers are filled with slivers of the same length. The predetermined length of the sliver to be processed is measured and the changing process of the cans is then initiated by the spinning station, which has first used up or almost used up its sliver supply. Empty or nearly empty containers are removed and filled containers are fed in using a changing device, either with all containers simultaneously or one after the other.
  • the object of the invention is to improve the efficiency or the degree of utilization of the automatic spinning machine, in particular by reducing the waiting times.
  • an automatic spinning machine is designated by 1 in total. It is an OE spinning machine, of which a machine frame 2 and an intermediate frame 3 is shown in the drawing. Both frames are on the floor 4 of a machine hall. Between the machine frame and the intermediate frame 3 there are 6 spinning positions, which are denoted by S 1 to S 6.
  • a continuous support 5 connects the spinning positions S 1 to S 6 to the machine frame 2, the intermediate frame 3 and further intermediate frames, not shown here, and an end frame which is also not shown here.
  • the other spinning positions that the automatic spinning machine 1 still has have not been shown here for the sake of simplicity. For the explanation of the invention, it is sufficient to assume that the automatic spinning machine 1 has only the 6 spinning positions S 1 to S 6.
  • the machine frame 2 contains the main drive device for the shaft 20 for driving the take-off roller 8 and the shaft 21 for driving the bobbin drive roller 9.
  • Another shaft 22 drives the spinning elements of the spinning boxes 7. This shaft is also driven by the central drive device of the machine frame 2.
  • the automatic spinning machine 1 is assigned a mobile automatic can changing device 25, a stationary automatic filling device 26 for sliver cans and an automatic transport device 27 for transporting the cans from the filling device 26 to the spinning positions S 1 to S 6 and for returning empty cans to the filling device 26.
  • the automatic spinning machine 1 has an electronic computer 28, which represents a data processing system and is intended to control the operation of the automatic spinning machine 1 and also to control the operation and coordination of the devices operatively connected to the automatic spinning machine 1.
  • the spin boxes or spinning devices 7 work automatically. They are able to take up and insert the sliver end presented by the can changing device 25, to carry out a piecing process and then to carry out the continuous spinning out of the sliver section.
  • a cross-wound bobbin of a predetermined size is created from the sleeve 10, which is initially still empty or contains fewer starting turns, and when this cross-wound bobbin is finished, the automatic spinning device 7 also takes care of the bobbin change and the re-spinning which may be necessary when changing the bobbin in a manner known per se.
  • the spinning devices 7 are provided with sliver length detection devices 29.1 to 29.6.
  • the spinning station S 1 has the sliver length detection device 29.1 and the spinning station S 6 has the sliver length detection device 29.6.
  • the sliver length detection devices 29.1 to 29.6 are coupled to feed rollers of the spinning devices 7, which are not shown here and are driven by the shaft 23, and detect and count their angles of rotation, so that the drawn-in sliver length can be determined from the angle of rotation, taking into account the diameter of the roller.
  • the drawing shows that under the spinning positions S 1 to S5 there are cans 11 to 15, the filling level of which is different. In the drawing, this is symbolized by the different height of the sliver content of the cans which are assumed to be translucent.
  • the mobile can changing device 25 has a symbolically illustrated, controllable gripping device with which filled cans can be placed on the transport device 27 from the transport device 27 to one of the spinning stations S 1 to S 6 or from one of the spinning stations.
  • the transport device 27 has an endless conveyor belt 31 which is guided at the ends via rollers 32, 33.
  • the front roller 32 is connected to a controllable stepper motor 34.
  • the filling device 26 consists of a stretch, the delivery 35 of which is connected to a controllable drive device 36.
  • the operative connection 37 leads to the stepper motor 34, the operative connection 38 to the drive device contained in the machine frame 2, the operative connection 39 to a rotation angle sensor 55 which is connected to the shaft of the drive motor 24 and which therefore the rotation angle of the shaft 23 driving the sliver drawing-in devices of the spinning devices 7 measures.
  • the active connection 40 leads to a belt counter 56.
  • the active connections 41 to 46 lead to the spinning devices 7 of the spinning stations S 1 to S 6.
  • the active connections 47 to 52 lead to the sliver length detection devices 29.1 to 29.6 of the spinning stations S 1 to S 6.
  • the active connection 53 leads to the mobile can changing device 25.
  • the operative connection 54 leads to the drive device 36 of the stationary filling device 26.
  • the computer 28 controls the automatic spinning machine 1 and its additional devices. It is programmable and contains all the equipment and units that a computer that normally controls machine production normally has.
  • the correlation between sliver length, sliver content, sliver runtime from the can and bobbin winding time of a full bobbin is set in a table in the computer 28 for all yarn finenesses and all sliver sections and sliver finenesses in question.
  • the correlations can be selected on a first keypad 57.
  • the computer then uses the selected correlations for all of its calculations and command output in order to spin out the relevant lot.
  • Various programs that have already been permanently programmed into the computer can be called up on a second keypad 58.
  • a first and a second start program of the automatic spinning machine, a program for normal running spinning operation and a batch end program can be called up.
  • an additional device not shown and described here, has sleeves 10 provided with initial turns and clamped in the bobbin frames 19 of the bobbins S 1 to S 6.
  • the ends 18 of the fiber yarn already present on the tubes 10 with just a few turns have already been automatically introduced into the yarn take-off points 59 of the spin boxes or spinning devices 7 against the later yarn take-off direction.
  • Empty cans stand vertically under the spinning positions S 1 to S 6.
  • the filling device 26 is ready for operation.
  • the can changing device 25 is also ready for operation. The same applies to 1 and the transport device 27.
  • the selected starting program provides that the filling device 26 fills a number of cans 11 to 16 corresponding to the number of spinning positions S 1 to S 6 with a different degree of filling from can to can, the transport device 27 these cans to the automatic spinning machine 1 and the can changing device 25 feeds the individual spinning positions S 1 to S 6 and that the spinning positions S 1 to S 6 then automatically carry out the piecing mentioned above after receiving the cans 11 to 16 at the spinning devices 7, whereupon the spinning program then takes effect.
  • the filling device 26 initially has no cans available. There are several ways to feed the empty cans to the filling device 26 and the program must be designed accordingly.
  • the computer 28 can, for example, use the operative connection 53 to cause the can changing device 25 to move to the individual spinning positions S 1 to S 6 in succession, to detect the empty can there and to place it on the conveyor belt 31, and then when all the cans are on the conveyor belt , the computer via the operative connection 37 causes the stepper motor 34 to move the conveyor belt 31 in the direction of the arrow 60 until all the cans are to the right of the delivery 35 on the belt section 31, which thus serves as a reserve magazine for empty cans.
  • the band section 31 is shown shortened due to the limited sheet format.
  • the computer 28 causes the stepper motor 34 to retract the belt 31 against the direction of the arrow 60 until, for example, the can 11 is under the delivery 35, which can be monitored and controlled by sensors.
  • the control sensors for centering the can 11 or the delivery 35 are not dealt with in more detail here.
  • the sole control with the aid of the stepping motor 34 is also conceivable.
  • the computer 28 then initiates via the operative connection 54 that the drive device 36 starts up the delivery 35, which then, according to the program, only fills the can 11 with so much sliver that its degree of filling is, for example, 20%. Then there is a feedback via the operative connection 54 to the computer 28, which then causes the stepper motor 34 to move the belt 31 against the direction of the arrow 60 by a spinning position division, that is to say to the left, the center distance of adjacent spinning positions. As a result, the next empty can comes under delivery 35. This would be the can 12, which would then be filled to 75%, for example.
  • the can 13 then has, for example, a degree of filling of 85%, the can 14 has a degree of filling of 50%, the can 15 has a degree of filling of 30% and the can 16, for example, a degree of filling of 100%.
  • the successive uneven filling of the cans is pre-programmed in the drive device 36 as a special program, and this special program is called up by the computer 28 via the operative connection 54.
  • the computer 28 As soon as the computer 28 receives the feedback via the active connection 54 that all the cans have been filled, it causes the stepping motor 34 via the active connection 37 to advance the conveyor belt 31 against the direction of the arrow 60 until a can next to a spinning station S 1 to S 6. Now, according to the program, the computer 28, via the operative connection 53, causes the can changing device 25 to move against the direction of the arrow 60 in order to successively set up the cans at the spinning stations and present the sliver end to the spinning devices 7. For this purpose, a chassis 62, which drives one of the rollers 63, 64 of the can changing device 25, receives a corresponding drive command.
  • a similar mode of operation of the can changing device 25 can be provided here.
  • the can changing device 25 would first be stopped by the spinning station S 6, and its activity now consists in the gripping device 30 gripping the can 16 standing on the conveyor belt 31 in front of the spinning station S 6, transported to the spinning station S 6 and there onto the Floor. At the same time, it also detects the sliver end and presents it to the spin box 7 of the spinning station S 6. Thereafter, the spinning station S 6 releases the can changing device 25 to continue traveling in the direction of the arrow 60. This onward journey ends at spinning station S 5, where the same work process takes place. So it goes on to the spinning station S 1, and only when all spinning stations have received their cans, the computer 28 via the active connection 23 causes the can changing device 25 to return to their starting position, which is shown in the drawing.
  • the second possibility of presenting filled cans to the automatic spinning machine 1 for the first time is that the can changing device 25 immediately drives to a spinning station, parks it and places the empty can on the conveyor belt 31, whereupon the computer 28 causes the stepping motor 34 via the operative connection 37, Advance the conveyor belt in the direction of arrow 60 until the can comes to rest under the delivery 35 of the filling device 26.
  • the delivery 35 switches off, and at the same time the stepper motor 34 receives the command from the computer 28 via the active connection 37, the same number of steps to run backwards, so that the conveyor belt 31 moves back again in the direction of arrow 60 the same stretcher and the filled can 16 comes to stand in front of the spinning station S 6, where the can changing device 25 is already ready to grasp the can and the spinning station Submit S 6.
  • the computer 28 receives feedback via one of the active connections 41 to 46, and then initiates the spinning on or the start of the relevant spinning station.
  • This immediate start is related to the entire automatic spinning machine 1, more effective than the common start of all spinning stations after receipt of their sliver cans.
  • the start program is now ended, and the computer 28 immediately switches automatically to the spinning program.
  • the drive device 36 of the filling device 26 is switched to its spinning program, which provides for all cans to be filled with a degree of filling of 100% in the future.
  • Each pitcher is expediently filled with a certain sliver length.
  • the can 11 of the exemplary embodiment is now generally empty first.
  • a feedback is sent to the computer 28 via the active connection 41, which, via the active connection 53, immediately causes the can changing device 25 to move in front of the spinning station S 1, remove the empty can there and place it on the conveyor belt 31.
  • the computer 28 After confirmation of completion, the computer 28 causes the stepper motor 34 to advance the belt 31 in the direction of the arrow until the empty can 11 is under the delivery 35, whereupon the computer 28 then causes the delivery 35 to 100% empty the can replenish.
  • the stepper motor 34 is caused to rotate the same number of steps in the opposite direction again, so that the can now filled returns to the spinning station S 1.
  • the can changing device There, prompted by the computer 28 or by its own sensors of the can changing device 25, the can changing device immediately takes action in order to present the filled can to the spinning station S 1 as quickly as possible, which then receives the start command after the completion of the confirmation by the computer 28.
  • the conveyor belt 31 could, for example, be set in a circle, for example using other conveyor belts.
  • the empty cans would then simply be placed on the conveyor belt 31 and the conveyor belt 31 then only had to advance against the direction of the arrow 60 until a filled can already placed on the conveyor 26 on the belt arrives at the relevant spinning position. This could be observed, for example, by the can changing device 25 and reported back to the computer 28 via the active connection 53, which then stops the stepper motor 34.
  • the can changing device 25 can, depending on the choice, either be moved to the illustrated rest position each time the can has been changed, or it can stop at the relevant spinning position and wait for its next use there, or it can take an inspection run at the automatic spinning machine 1 and waiting and waiting that she is stopped on her inspection trip by a spinning station that is in need of a can change.
  • the spinning operation can now continue for hours, days or weeks, but at some point the time for the end of the lot or the time for a lot change comes.
  • the batch termination program can be started either in time by the computer or manually. From the start of the batch termination program, it is clear how large is the amount of sliver that can be processed at each individual spinning station from the start. The number of the maximum number of coils that can still be produced is thus fixed. Since it is also known in which time the amount of sliver can be processed, the batch end program can be started either automatically or manually at the corresponding earlier point in time.
  • the automatic spinning machine 1 only has a maximum spinning time available, which corresponds to a maximum still available sliver running time, sliver length or bobbin winding time for each spinning station.
  • the down-counting belt counter 56 is started via the active connection 40, which from now on determines and displays the maximum still available sliver running time or sliver length for the individual spinning station at any time.
  • the tape counter 56 is controlled by the rotation angle sensor 55. This continuously counts the angle of rotation of the shaft 23, which drives the feed rollers for the sliver 17. The length of the sliver passing through the sliver feed point 6 then results from the diameter of the feed roller in conjunction with the angle of rotation.
  • the computer 28 determines, based on the maximum available tape length, how many full bobbins can be finished at this spinning station within the maximum possible spinning time still available, and then automatically specifies the spinning station, only to finish the calculated number of coils.
  • the batch termination program also provides for automatic sliver length detection to be carried out for the relevant spinning station from the start of completion of the first bobbin of this number. In the exemplary embodiment, this is done by the sliver length detection devices 29.1 to 29.6.
  • the program also provides that if there is an impending can change at this spinning station or if the can becomes empty, it is automatically determined how much sliver the new can must contain so that the specified number of bobbins can be finished.
  • the amount of sliver arithmetically results from the sum of the full sliver content of the not yet wound bobbins and the bobbin currently in progress minus the amount of sliver that has already run onto the bobbin.
  • the determined fiber sliver filling quantity is communicated by the computer 28 via the operative connection 54 to the filling device 26, whereupon the delivery 35 only fills the specified filling quantity into the relevant can of the requesting spinning station.
  • the empty can is placed on the conveyor belt 31 by the can changing device 25, moved to the filling device 26, filled there with the predetermined filling level, moved back again and delivered to the spinning station by the can changing device 25.
  • the sliver is then used up just at the point in time when the last bobbin is finished. The same applies to all other spinning positions. There is no remaining sliver and all bobbins contain their specified maximum amount of yarn.
  • the first spinning station that has finished spinning the first lot thus immediately spins the second lot.
  • the filling device 26 is immediately switched over to the new batch.
  • a different degree of filling the Jugs of the new lot are not necessary because the empty jugs of the old lot already have a different filling level and because an empty jug is then immediately exchanged for a filled jug of the new lot.
  • There is no fear of swapping the completely wound bobbins of the old lot with bobbins of the new lot because when a can is emptied, one last bobbin is finished and thus the bobbin change takes place in connection with the can change, which can be monitored automatically.
  • the exemplary embodiment provides a common belt counter 56 for all spinning positions of the automatic spinning machine 1. Instead, a downward-counting sliver counter that detects the individual sliver intake can be arranged at each spinning station.
  • the sliver length detection devices 29.1 to 29.6 already present at the spinning stations could then be integrated in the down-counting sliver counters.
  • Each spinning station would then have its own maximum possible winding time available, which could possibly differ somewhat from the maximum possible winding time of neighboring spinning stations.
  • the downward-counting belt counter is now sensor-linked to the actual belt run of the individual spinning station, which makes the measurement of the sliver content of the last can somewhat more precise in cases in which the end of the individual winding time coincides with the end of the maximum possible winding time.
