Definitions

  • the present invention relates to a spinning machine with a plurality of work stations arranged next to one another, each of which has a spinning device that can be subjected to negative pressure for the production of a thread and a suction nozzle that can be subjected to negative pressure for locating a thread end on a bobbin, and with a first negative pressure system which has at least a first , has a vacuum channel extending along the work stations of the spinning machine and at least one first vacuum source, the spinning devices of the work stations being connected to the first vacuum system.
  • the invention also relates to a method for operating such a spinning machine, in which the spinning devices of the work stations are subjected to negative pressure by means of a first negative pressure system.
  • the suction nozzle and the thread storage nozzle are arranged in the movable maintenance device (s). If one of the spinning positions needs to be serviced, it will be positioned Maintenance device in front of the spinning station in question and docks to a machine-length vacuum channel running above the spinning stations.
  • the individual maintenance units of the maintenance facility can thereby be supplied with negative pressure. In such machines, however, only a single spinning station can be serviced or spun at the same time by a maintenance device. There are therefore hardly any bottlenecks in the vacuum supply in such machines.
  • a suction nozzle, a thread storage nozzle and / or other working elements that can be acted upon by negative pressure are arranged in this case at each individual spinning station.
  • the DE 10 2005 036 485 A1 For example, such a spinning machine is known, which is designed as a semi-automatic rotor spinning machine. If, in such spinning machines, a maintenance process which requires negative pressure is carried out simultaneously at several spinning positions, it is often no longer possible to provide a sufficient negative pressure level. the DE 10 2005 036 485 A1 therefore suggests arranging a second vacuum source in the machine, which can be switched on manually if necessary. It is at the discretion of the operator when it is necessary to switch on the second vacuum source and when it is not. It is therefore not always possible to provide an optimal negative pressure level.
  • the DE 10 2007 053 467 A1 therefore proposes an open-end rotor spinning machine in which the second vacuum source is automatically switched on when required.
  • the second vacuum source should be regulated according to the vacuum requirement of the suction nozzles.
  • the suction nozzles After running the DE 10 2007 053 467 A1 are the suction nozzles on each side of the machine connected to a separate vacuum channel, which is connected to the vacuum system of the spinning machine. If a bobbin change is required at one of the spinning stations, the drive of the second vacuum source is automatically switched on by the central control unit of the spinning machine, so that the suction nozzle can be supplied with an increased vacuum level.
  • the object of the present invention is to further improve the vacuum supply to the spinning stations of a spinning machine with suction nozzles belonging to the work station.
  • a spinning machine contains a large number of workstations arranged next to one another, each of which has a spinning device that can be subjected to negative pressure for producing a thread and a suction nozzle that can be subjected to negative pressure for locating a thread end on a bobbin, as well as at least one first negative pressure system, which has at least one first, along the Has jobs of the spinning machine extending vacuum channel and at least one first vacuum source.
  • the spinning devices of the work stations are connected to the first vacuum system.
  • the spinning machine have at least one second negative pressure system, which has at least one second negative pressure channel extending along the workstations of the spinning machine and at least one second negative pressure source, the suction nozzles at least a first partial number of the workstations, preferably all workstations, to the second Vacuum system are connected, and that the at least one first and the at least one second vacuum system are pneumatically completely separated from one another.
  • the spinning devices of the workstations are activated by means of a first Vacuum system applied with negative pressure.
  • the suction nozzles are subjected to at least a first partial number of the work stations by means of a second negative pressure system with negative pressure, the first negative pressure system and the second negative pressure system being operated pneumatically independently of one another.
  • the suction nozzles can be supplied completely independently of a main negative pressure for the spinning devices. Sufficient negative pressure is thus still available for the thread search even if the first negative pressure system is overloaded, for example due to a large number of processes or connected negative pressure consumers. Such a situation can occur in particular when the machine is restarted and / or when a yarn batch is started in the case of multiple batches. Thanks to the second vacuum system, the suction nozzles can nevertheless carry out the thread search at other workplaces and the thread end found can be made available for the subsequent piecing process. The piecing can then take place as soon as sufficient negative pressure is available again in the first negative pressure system.
  • the pneumatically separated vacuum systems can also be provided separately on each longitudinal side of the spinning machine. In this case there would be two first and two second vacuum systems. Also is it is conceivable that further, pneumatically separated negative pressure systems are provided for further negative pressure consumers.
  • suction nozzles of all work stations are subjected to negative pressure by means of the second negative pressure system.
  • the suction nozzles can thereby be supplied with a higher negative pressure level, which can preferably also be set separately, completely separately from the spinning devices.
  • the first negative pressure system can or is acted upon by a first negative pressure level and the second negative pressure system with a second negative pressure level.
  • the second negative pressure level is preferably greater than the first negative pressure level.
  • the second negative pressure level is lower than the first or both are equally high. This can, for example, be determined in an application-specific manner, with the vacuum levels also being able to be set differently at different times.
  • the first and the second negative pressure system can each be set independently of one another, preferably can be regulated or, in the method, are set, preferably regulated, independently of one another.
  • the two negative pressure systems each have their own negative pressure source, which is each provided with its own drive.
  • the vacuum level can be set in each vacuum system to the demand currently required, which contributes to energy-saving operation.
  • the different pressure levels can in this case different compressed air sources or by a drive with different speeds can be realized.
  • each of the work stations furthermore has a working element that can be subjected to negative pressure, in particular a thread storage nozzle, the working elements of the work stations being connected to the first negative pressure system.
  • the working organs that can be acted upon by negative pressure generally require less negative pressure, so that it is sufficient to connect them to the first negative pressure system, which also supplies the spinning devices.
  • thread nozzles which handle the thread when it is attached, and / or suction nozzles, which suck off pieces of thread or impurities, are to be mentioned as working organs of the work stations that can be subjected to negative pressure.
  • the thread nozzles also include thread catching nozzles in addition to the thread storage nozzles already mentioned.
  • each of the suction nozzles and / or each of the working elements that can be subjected to negative pressure can be individually shut off from the negative pressure system assigned to it by means of a shut-off device. It is also advantageous in the method if the suction nozzles and / or the working elements that can be subjected to negative pressure are shut off from the negative pressure system assigned to them by means of a shut-off device when they are not in operation. Both the suction nozzles and the working elements that can be acted upon by negative pressure are only required temporarily to carry out certain maintenance activities. By means of the shut-off device, these can be shut off when they are not needed, so that they are not unnecessarily subjected to negative pressure.
  • each of the suction nozzles and / or each of the working elements that can be acted upon by negative pressure can optionally be connected to the first or to the second negative pressure system by means of the shut-off device.
  • the suction nozzle (s) for locating the thread end is / are shut off from the second negative pressure system at at least a further partial number of the work stations and is / are connected to the first negative pressure system. Even if the suction nozzles and / or the working elements that can be acted upon by negative pressure are basically connected to one of the two negative pressure systems, they can thereby also be connected to the other negative pressure system, at least temporarily.
  • the suction nozzles can also be connected to the first negative pressure system with the lower negative pressure level at at least a partial number of the work stations and can thus be operated in a more energy-saving manner. It is also conceivable, if, for example, several workplaces are to be spun at the same time, to temporarily connect the working elements to which negative pressure can be applied, in particular the thread storage nozzles, to the second negative pressure system in this case.
  • the temporary connection of the suction nozzles and / or the working elements to which negative pressure can be applied to one of the two negative pressure systems can preferably also be carried out in relation to the yarn section.
  • suction nozzles for locating the thread end are optionally connected to the first or to the second vacuum system, depending on the type of thread produced. As already mentioned, this can also be done in relation to the yarn section.
  • the suction nozzles of a partial number of work stations which process a first yarn section can be connected to the first vacuum system and the suction nozzles of a further partial number of work stations which process a second yarn section can be connected to the second vacuum system.
  • the shut-off device has a multi-channel design, the shut-off device being connected to the first negative pressure system via a first channel and to the second negative pressure system via a second channel.
  • the shut-off device can contain, for example, a slide valve or rotary valve.
  • the two channels of the shut-off device can also be shut off independently of one another by means of two separate shut-off elements.
  • the thread search can be carried out in a particularly reliable manner, and after the thread has been found, a switch can be made to an energy-saving, lower negative pressure level for holding and handling the thread.
  • FIG. 1 shows a front view of a spinning machine 1 in a schematic overview representation.
  • the spinning machine 1 has a multiplicity of work stations 2 arranged next to one another, which in the present case are arranged between two frames (not designated).
  • Each of the work stations 2 has a spinning device 3 to which a fiber material is fed from a feed device 27. If the spinning device 3 is designed as a rotor spinning device, the feed device 27 is an opening roller. If, on the other hand, the spinning device 3 is designed as an air-jet spinning device, the fiber material is usually fed in via a drafting device.
  • the thread 4 produced is withdrawn by means of a withdrawal device 28 and wound onto a spool 6.
  • the spinning machine 1 also has a central control unit 15. This can interact with job controls 29 of the individual jobs 2, as in the Figures 2 and 3 shown.
  • each of the work stations 2 furthermore has a work station's own suction nozzle 5. If the suction nozzle 5 has found the thread end and sucked it in, it can be passed on to further handling organs of the work station 2, which can work mechanically or pneumatically, for re-piecing.
  • the work station 2 has, for example, working organs 16 that can be acted upon by negative pressure, such as thread storage nozzles, thread catching nozzles and the like.
  • a workstation-specific thread storage nozzle is shown here.
  • the work stations 2 can also have further work organs 16 that can be subjected to negative pressure, for example thread catching nozzles, which are required when the thread 4 is attached, or suction nozzles for sucking off pieces of thread or impurities at the work station 2.
  • the spinning machine 1 also has a first negative pressure system 7 and a second negative pressure system 10. Negative pressure is required during regular operation for the spinning devices 3 and during piecing for the spinning devices 3, the suction nozzles 5 and the thread storage nozzles shown here by way of example as working element 16. The negative pressure is also required at different times during piecing. For example Initially only the suction nozzle 5 requires negative pressure to seek out the thread end, while the spinning device 3 only requires negative pressure after the thread end has been found. The thread storage nozzle also requires negative pressure only after the thread end has been found.
  • the two negative pressure systems 7, 10 are pneumatically completely separated from one another.
  • the first negative pressure system 7 has at least one first negative pressure channel 8, which extends along the work stations 2.
  • the first vacuum channel 8 is acted upon by a first vacuum source 9, which is connected to the first vacuum channel 8 via a first filter box 13.
  • the second negative pressure system 10 also has a second negative pressure channel 11, which extends along the work stations 2 and is acted upon by a second negative pressure source 12 via a second filter box 14.
  • a filter 23 is arranged in each of the two filter boxes 13, 14.
  • a first drive 25 is assigned to the first vacuum source 9 and a second drive 26 is assigned to the second vacuum source 12.
  • both the first and the second vacuum channel 8, 11 extend over the entire length of the spinning machine 1 or the entire plurality of work stations 2.
  • the first vacuum system 7 has several first vacuum channels 8 which each extend only over a part of the work stations 2 and are acted upon by a plurality of first negative pressure sources 9.
  • several first negative pressure systems 7 and / or several second negative pressure systems 10 are present, each of which are pneumatically independent of each other. For example, on a spinning machine 1, the two longitudinal sides of the spinning machine could be subjected to negative pressure separately from one another.
  • a first negative pressure system 7 and a second negative pressure system 10 that is to say a total of four negative pressure systems 7, 10, would be present on each of the two longitudinal sides.
  • Mixed forms are of course also conceivable, for example with two separate first negative pressure systems 7 for the spinning negative pressure, but a common second negative pressure system 10 for the suction nozzles.
  • the spinning devices 3 of all work stations 2 are connected to the first vacuum system 7.
  • the suction nozzles 5 of all work stations 2 are also connected to the second negative pressure system 10, or here to the second negative pressure channel 11.
  • the negative pressure level pU2 of this second negative pressure system 10 is advantageously set significantly higher than the negative pressure level pU1 of the first negative pressure system 7. In this way, a high yarn search efficiency can be achieved without unnecessarily influencing the spinning conditions in the spinning devices 3.
  • the second vacuum source 12 has its own second drive 26, an optimal second vacuum level pU2 can also be set manually or automatically in every operating state or even with a different number of currently active suction nozzles 5 and, if necessary, also regulated by a separate control unit.
  • the thread storage nozzles of all work stations 2 are also connected to the first vacuum system 7 according to the present exemplary embodiment. This is especially true in Figure 2 can be seen, which shows a schematic side view of a work station 2 of the spinning machine 1.
  • the thread storage nozzles or, in general, the working elements 16 which can be acted upon by negative pressure, generally only require a lower negative pressure level, so that the connection to the first negative pressure system 7 with the first, lower negative pressure level pU1 is more advantageous in terms of energy.
  • the multiplicity of work stations 2 is also possible for the multiplicity of work stations 2 to be subdivided into two or more groups or partial numbers 21, 24.
  • the work stations 2 on the illustrated longitudinal side of the spinning machine 1 are divided into a first part number 21 and a second part number 24.
  • the workplaces 2 of the spinning machine 1 are self-sufficient, ie they can automatically resume the spinning process after an interruption, the workplaces can be subdivided into groups completely independently of structural conditions such as sections or longitudinal sides of the spinning machine 1.
  • the subdivision into such groups is preferably carried out on a batch basis, so that correspondingly the first number of parts 21 processes a first batch of yarn and the second number of parts 24 processes a second batch of yarn.
  • a subdivision into even more groups or partial numbers 21, 24 can also take place.
  • Workplaces 2 belonging to a partial number 21, 24 do not necessarily have to be adjacent to one another.
  • the suction nozzles 5 of the second number 24 can be connected to the first negative pressure system 7. This can be dependent, for example, on the position of the respective work station 2 within the machine, since the negative pressure level pU1, pU2 near the negative pressure sources 9, 12 is usually higher than at a greater distance from them.
  • the partial numbers 21, 24 can also be connected to the first or to the second vacuum system in relation to the batch. How with the Figures 4 and 5 is still being carried out, this can also be done temporarily or alternately.
  • FIG Figure 2 shows a workstation 2 of the spinning machine 1 of FIG Figure 1 in a schematic, partially sectioned side view.
  • the suction nozzle 5 is connected to the second negative pressure system 10 and the spinning device 3 and the thread storage nozzle to the first negative pressure system 7.
  • both the thread storage nozzle and the suction nozzle 5 can each be shut off individually by means of an independent shut-off device 17, that is, from the negative pressure system 7, 10 to which they are connected, separable.
  • the suction nozzles 5 and the thread storage nozzles can thereby be separated from the negative pressure when they are not required.
  • each shut-off device 17 contains a shut-off element 18 which, in the present example, is controlled by the workstation control 29.
  • the shut-off element 18 could also be activated by the control unit 15.
  • Figure 3 shows a work station 2 of a spinning machine 1 according to a second embodiment in a schematic, sectional side view.
  • the suction nozzle 5 can optionally be connected both to the first negative pressure system 7 with the first, lower negative pressure level pU1 and to the second negative pressure system 10 with the second, higher negative pressure level pU2.
  • This can e.g. B. be advantageous in the case of multi-part occupancy of the spinning machine 1, since the negative pressure system 7, 10 with the lower negative pressure level pU1, pU2 can be selected in order to save energy in the case of yarn-part-specific lower demands on the suction effect.
  • the present shut-off device 17 is designed with multiple channels for this purpose.

  • FIG 4 shows a schematic representation of a further shut-off device 17 in a first state.
  • the two channels 19, 20 cannot be shut off by means of separate shut-off elements 18, but the shut-off device 17 has only a single shut-off element 18 for shutting off the suction nozzle 5.
