Definitions
- the present invention relates to an air-spinning machine for producing a yarn from a fiber structure, wherein the spinning machine comprises at least one spinning station, wherein the spinning station has a vortex chamber with an inlet opening for the fiber structure and a Garnsentelement at least partially extending into the vortex chamber with an inlet mouth for the yarn , wherein the vortex chamber in the direction of the Garnticianselements associated spinnerets are, can be introduced via the air in the vortex chamber to impart rotation to the fiber structure in the region of the inlet mouth, wherein the vortex chamber is associated with an outlet channel, on the at least a part of the Spinning nozzles introduced air is discharged, and wherein the Garnticianselement has an adjacent to the inlet port discharge channel through which the yarn from the vortex chamber is removable.
- the spinning machine comprises at least one spinning station, wherein the spinning station has a vortex chamber with an inlet opening for the fiber structure and an at least partially extending into the vortex chamber yarn formation element with an inlet mouth for the yarn associated with the vortex chamber in the direction of the Garn Strukturselements aligned spinneret over which during the yarn production air is introduced into the vortex chamber to impart rotation to the fiber strand in the region of the inlet mouth of Garn Strukturselements, wherein the vortex chamber is associated with an outlet channel, on the at least one part the air introduced through the spinnerets during yarn production is discharged, and wherein the yarn forming member has a discharge duct adjacent the inlet mouth over which the yarn passes during yarn production the vortex chamber is withdrawn.
- Generic air-jet spinning machines serve to produce a yarn from an elongated fiber structure by means of a vortex air flow generated by the spinnerets within the vortex chamber.
- the outer fibers of the fiber composite are wound around the inner fibers (core) in the area of said inlet opening of the yarn formation element, so that a stable yarn with a true twist results, which is finally removed from the vortex chamber via the extraction channel and wound onto a bobbin can be.
- Object of the present invention is therefore to propose an air-spinning machine whose vortex chamber on particularly simple, yet reliable Can be freed of accumulated during the spinning process impurities.
- the air-spinning machine is characterized in that it has at least one cleaning member with an inlet and an outlet for a cleaning medium, wherein a cleaning medium supplied to the cleaning member via the inlet cleaning medium during the cleaning step via the outlet into the vortex chamber can be introduced.
- the air-spinning machine has a cleaning device comprising the cleaning device, with the help of a particular automatic cleaning of the vortex chamber and thus also the Garn Strukturselements is possible.
- the fluidizing chamber is supplied with a liquid, gaseous or solid (eg pulverulent) cleaning medium.
- the cleaning member is in this case preferably via its inlet to a pump or a cleaning medium leading overpressure line in combination, so that the cleaning medium is pressed as a result via the outlet into the vortex chamber or its inlet opening.
- the cleaning medium eventually takes the way to the surface of the yarn-forming element, which also has to take the fiber structure during the spinning process. This results in a recording of the impurities, which can finally be discharged together with the cleaning medium from the vortex chamber.
- the invention provides that the outlet of the cleaning member during a cleaning step sealing contact with the inlet opening of the vortex chamber can be brought into contact, so that a cleaning member supplied via the inlet cleaning medium during the cleaning step through the outlet and finally via the inlet opening into the vortex chamber can be introduced ,
- the cleaning member is thus a separate from the wall surrounding the vortex chamber and preferably movably mounted component and serves as a coupling member between a reservoir for the cleaning medium and the wall surrounding the vortex chamber. If a cleaning step is to be carried out, all that is required is to stop the supply of the fiber dressing and bring the cleaning element into liquid-tight or gas-tight contact with said wall. The supply of the cleaning medium finally takes place via the outlet of the cleaning member and the adjacent inlet opening of the vortex chamber.
- the outlet channel of the vortex chamber is connected to a switchable flow switch, which is connected on the one hand with an air discharge line and on the other hand with a line for the removal of the cleaning medium.
- the discharge channel can either pass into the air discharge line or into the line for removing the cleaning medium.
- both the air during the spinning process and the cleaning medium during the cleaning step leaves the vortex chamber via the same opening, namely the outlet channel.
- a flow switch is placed in the outlet channel, preferably by means of a drive via a control unit.
- the line for the removal of the cleaning medium can finally with a storage container for the cleaning medium be connected so that the cleaning medium during the cleaning step in the circulation are promoted (possibly with the interposition of a filter device for removing the impurities from the cleaning medium).
- the vortex chamber is assigned a separate discharge channel for discharging the cleaning medium introduced into the vortex chamber during the cleaning step.
- the cleaning medium does not leave the vortex chamber above the outlet channel provided for the exit of the air (which is for example connected to a vacuum source). Rather, there is a separate channel through which the cleaning medium is withdrawn during the cleaning step. This channel can in turn be connected to a storage container and / or a pump for the cleaning medium.
- the outlet channel or the discharge channel are also placed in a plan view of the inlet mouth, preferably on the opposite side of the inlet opening of the vortex chamber to ensure that the cleaning medium must flow around the Garn avoirselement. It is particularly advantageous if the cleaning member identifies a seal in the region of the outlet. In this way it can be ensured in a simple manner that during the cleaning step, no cleaning medium between the cleaning member and the wall surrounding the vortex chamber, on which the cleaning member is applied, can escape. Rather, the entire cleaning medium supplied to the cleaning member via its inlet flows through the inlet opening into the vortex chamber, even if the cleaning medium is pressed in with a certain overpressure.
- the seal may be formed as a ring seal and consists for example of a rubber surrounding the outlet of the cleaning device.
- the cleaning member is in communication with a carrier element and with the aid of which is movable relative to the inlet opening of the vortex chamber. This is particularly advantageous because the inlet opening must be accessible during the normal spinning process for the fiber structure.
- the cleaning member is located on a support element (for example in the form of a drive arm having a drive), the cleaning member for the cleaning step can be moved in the direction of the inlet opening, for example pivoted. After completion of the cleaning step, the cleaning member is finally moved away from the inlet opening so far that the vortex chamber can be fed again a fiber structure.
- the air-spinning machine comprises a plurality of spinning units, wherein each spinning stations own or a group of several spinning stations is assigned a common cleaning member, wherein the cleaning member in the latter case the individual spinning stations is as needed deliverable.
- the cleaning member may in this case, as described, be associated with a carrier element, which controls the cleaning member in dependence on the cleaning step parameters (operating time of the air spinning machine, to be spun Fiber material, spinning speed, etc.) of the respective spinning station is delivered.
- the cleaning step parameters operating time of the air spinning machine, to be spun Fiber material, spinning speed, etc.
- the air-spinning machine comprises a plurality of spinning stations and if the cleaning device is part of a service robot of the air-spinning machine patrolling along the spinning stations.
- Corresponding service robots are conventionally used to initiate re-spinning in the event of a yarn breakage or failure, or to replace a full bobbin with an empty bobbin. If the service robot now additionally or exclusively has the described cleaning device, it is possible to clean all or a plurality of the spinning positions of an air-jet spinning machine with only one cleaning element.
- the service robot can also have its own storage container with cleaning medium, a pump for introducing the cleaning medium into the vortex chamber, or also a filter device for separating the impurities removed from the cleaning medium from the cleaning medium.
- the service robot can also have a coupling system with which it can be connected to the spinning unit to be cleaned with a line system of the air-spinning machine which carries the cleaning medium. If the cleaning medium is under a certain overpressure and a discharge line for the cleaning medium already passed through the vortex chamber is present, it is possible to dispense with a self-powered pump.
- the air-spinning machine has a storage container for the cleaning medium, which communicates with the cleaning member and / or with the discharge channel or the discharge channel of the vortex chamber or can be brought into connection.
- the storage container can in this case attach to the machine frame of the air spinning machine or else be part of the service robot.
- the storage container Preferably with a pumping and / or filter device in contact to promote the cleaning medium or to be able to free from impurities. It is also conceivable to combine the cleaning member with a disposable cartridge, taken from the fresh cleaning medium and can be returned to the contaminated cleaning medium after passing through the vortex chamber.
- the method according to the invention for cleaning a vortex chamber of an air-spinning machine is characterized in that a cleaning medium is introduced into the vortex chamber via the inlet opening during a cleaning step during which the yarn production is interrupted, and that the cleaning medium returns after passing at least part of the vortex chamber is removed from this.
- the vortex chamber is thus automatically cleaned with the aid of a cleaning medium to be described later, as soon as a cleaning medium is introduced into the vortex chamber.
- the cleaning medium flows into the vortex chamber and in this case takes the same path that the fiber structure also takes during the spinning process. In other words, the cleaning medium comes into contact with exactly the locations of the vortex chamber (inner surface, surface of the yarn formation element), which are most often covered with corresponding impurities.
- the cleaning medium can also be removed via a separate discharge channel.
- the cleaning medium is supplied via a separate, movably mounted cleaning member, the introduction begins, for example, as soon as the cleaning member has been sealingly brought into contact with the wall having the inlet opening (the cleaning member can, for example, after interrupting the yarn production by means of a driven support member, for example by means of a Carrier arm, moved to its cleaning position, for example, be pivoted).
- the invention provides that at the beginning of the cleaning step, an outlet of the cleaning member is sealingly brought into contact with the inlet opening of the vortex chamber, and that the cleaning medium is introduced via the outlet of the cleaning member in the vortex chamber. If the outlet and / or the wall surrounding the inlet opening has, for example, a seal, it can be prevented that the cleaning medium also escapes to the outside when subjected to overpressure at the connection point between the cleaning member and the wall surrounding the vortex chamber.
- a liquid for example a cleaning agent or solvent or a carrier fluid mixed therewith, for example in the form of water
- a bulk material eg a fine-grained metal, sand or plastic powder
- the cleaning medium is heated before its use to increase the cleaning effect in addition.
- the cleaning medium is a powder or a powder-air mixture
- the air entering via the spinnerets produces an air-powder vortex which frees the yarn-forming element from impurities, similar to a sandblasting device.
- the fluidizing chamber is supplied with a liquid cleaning medium (eg a fat-dissolving fluid),
- a liquid cleaning medium eg a fat-dissolving fluid
- the cleaning medium is sucked out of the vortex chamber via the outlet channel, via which air is removed during yarn production, or a separate discharge channel.
- a flow switch may be present after the outlet channel, which must be passed by the air (during the spinning process) or the cleaning medium (during the cleaning step).
- the flow switch can be brought, for example by means of a drive and a controller in the respective position. If the vortex chamber has a separate discharge channel for the cleaning medium, it may be advantageous if the outlet channel is closed during the cleaning step and the discharge channel during the spinning process in order to prevent the respective medium from escaping via the wrong exit.
- the supply of the cleaning medium is stopped and then the cleaning member is again removed from the inlet opening of the vortex chamber and the production of the yarn is started.
- FIG. 1 shows a schematic sectional view of a section of a spinning station of an air-spinning machine according to the invention.
- the air-spinning machine usually includes a drafting system, not shown, which with a Fiber structure 2, for example in the form of a doubled sliver 2, is supplied.
