Definitions
- the invention relates to a device according to the preamble of the independent Claim.
- the device is used to produce a spun yarn one of the device fed, loose fiber strand, the fiber strand through a vortex chamber is pulled, in which the fibers of a vortex flow of a fluid exposed and thereby spun into a yarn.
- Spinning devices of the above type are known, for example from the Publications US-5528895 or US-5647197 (both Murata). These devices have a fiber feed channel and a Garnabzugkanal, wherein the Output region of the fiber feed channel substantially against the Entrance of the Garnabzugkanals is directed and the exit opening of the Fiber feed channel with a distance to the input opening of Garnzugkanals is arranged. In the range of this distance, the vortex flow is generated.
- a Spin stop means e.g., eccentric edge over which the fibers are pulled, or im essentially concentric pin around which the fibers are guided).
- the entrance of the Garnabzugkanals usually has the shape of a slender Spindle, around which a drainage channel with a substantially annular Cross section runs.
- the discharge channel leads from the equipped as a vortex chamber Cavity between fiber feed channel and Garnzugkanal and runs in essentially parallel to the yarn withdrawal channel
- the vortex chamber has an im is substantially the same diameter as the entrance area of the discharge channel and with nozzles directed tangentially into the chamber for the injection of a fluid (for example air) equipped.
- the fluid injected into the vortex chamber passes through the bleed passage aspirated, with the vortex flow generated in the vortex chamber around the Continue the yarn removal channel (spindle) into the drainage channel.
- the vortex chamber and an input region of the discharge channel thus provide a substantially functional unit serving the rotation distribution.
- the Garnabzugkanal the optionally arranged rotating, can contribute to the rotation, wherein then by various means it is ensured that the fibers against the Outside of the Garnabzugkanals pressed and thereby taken better become.
- the cross sections of the fiber feed channel, Garnabzugkanal and discharge channel are small compared to the mean length of the fibers to be processed.
- the length of the Fiber feed channel is designed such that at least a portion of the fibers whose Leading end has already reached the areas of Garnabzugkanals, in Input range of the fiber feed channel is still held (for example, between Delivery rollers of the fiber feed duct upstream drafting).
- the with the described method produced yarns show because even a core of essentially in Garnvorlindsraum extending fibers or fiber regions without significant Rotation and an outer area in which the fibers or fiber areas around the Core are turned around.
- This yarn construction comes about after a model explanation by the fact that leading ends of fibers, in particular fibers whose trailing Areas are still held upstream of the fiber feed channel, in the essentially pass directly into the Garnabzugkanal, but that trailing Fiber areas, especially if they are in the entrance area of the Fiber supply channels are no longer held by the vortex effect of the Pulled fiber strand and then rotated around the resulting yarn. It can also occur that leading ends of fibers due to the vortex effect the fiber structure are spread while the trailing end in the central Area of fiber structure remains, resulting in the corresponding yarns observed loops leads.
- fibers are at the same time both in the resulting yarn integrated, whereby they are pulled into the Garnabzugkanal, as well as the Vortex flow exposed to them centrifugally, ie from the inlet opening of the Thread take-off channel accelerates away and pulls into the drainage channel.
- the by the Vortex flow from the fiber structure drawn fiber areas form one in the Entrance opening of Garnabzugkanals opening fiber vortex whose longer Sharp spirally outward around the spindle - shaped entrance area of the Garnabzugkanals wind and in this spiral against the force of flow in the Discharge channel to be pulled against the entrance opening of the Garnabzugkanals.
- the described, known spinning process is characterized in that it is very high spinning speeds allowed (up to ten times higher spinning speeds than for ring spinning process). On the other hand, it turns out to be difficult with the method to avoid a high fiber output and one for a high yarn quality To obtain enough high fiber content in the twisted outer area of the yarn.
- the Invention is therefore the task of a device for spinning means To create vortex flow, with which device it should be possible, the To reduce fiber disposal over the prior art, the yarn quality should be at least the same.
- the invention is based on the idea of the vortex chamber and the discharge channel functional in such a way that the fiber vortex does not move downstream into the Drain channel can continue, but on the vortex chamber, that is to one of the Drain channel functionally separated space remains limited.
- This idea is realized in that the vortex chamber is bounded downstream by a wall and that the fluid is completely discharged through this wall into the discharge channel becomes.
- In the center of the vortex chamber downstream bounding wall is the Input opening of Garnabzugkanals arranged.
- the the vortex chamber The downstream wall has no rotation-dividing function, that is to say does not rotate.
- For the routing of the fluid are in this wall around the Inlet opening of Garnabzugkanals distributed, in the discharge channel or in Discharge channels opening openings provided, which is also an annular Opening can be summarized.
- FIG. 1 shows the vortex chamber region of a device according to the state of the art, with which a loose fiber structure 2 fed through a fiber feed channel 1 is given a rotation in a vortex chamber 3, resulting in a spun yarn 4 which is drawn off through a yarn withdrawal channel 5 ,
- the vortex flow is generated in the vortex chamber 3 by injecting a fluid, for example air, through nozzles 6 opening tangentially into the chamber.
- the fluid is discharged through a bleed passage 7, the bleed passage 7 having an annular cross section around the yarn withdrawal passage 5 and its entrance portion having substantially the same diameter as the swirl chamber 3, so that the swirl flow generated in the swirl chamber continues into the bleed passage and from the fiber structure by the centrifugal effect of the vortex flow leached out fiber regions 8 in the discharge channel sprialförmig outside the spindle-shaped entrance area of Garnabzugkanals 5 put.
- Swirl chamber 3 and inlet area of the discharge channel 7 constitute a functional unit, so that fibers that are not incorporated into the resulting yarn are likely to be flushed by the fluid into the discharge channel and thereby lost for the resulting yarn.
- the eccentric to Garnabzugkanal 5 is arranged at the outlet opening 9 of the fiber feed channel 1 at the outlet opening 9 of the fiber feed channel 1 arranged as an anti-rotation means. It is also known as a spin stop agent Insert needle (pin) arranged concentrically to the yarn withdrawal channel, which needle represents a temporary yarn core.
- FIG. 2 shows a first, exemplary embodiment of the device according to the invention.
- the swirl chamber region is shown in section, that is to say the exit region of the fiber supply channel 1 with outlet opening 9 and swirl stop means 10 and the entrance region of the yarn withdrawal channel 5 with inlet opening 11, and swirl chamber 3 and outlet channel 7 which, as in FIG having a substantial annular cross-section.
- Discharge channel 7 Between swirl chamber 3 and discharge channel 7 is a circular disk-shaped wall plate 20 arranged, which carries the input opening 11 of Garnabzugkanals 5 and around this inlet opening 11 distributes a plurality of openings 21 through which the fluid from the vortex chamber 3 enters the discharge channel 7.
- the Discharge channel 7 with annular cross section also be replaced by a plurality of aligned on the openings 21 discharge channels.
- the fiber vortex is therefore limited to the Vortex chamber 3 and the entrapped fibers are unable to integrate fibers to keep better in the swirling fiber structure.
- the fiber density in the vortex chamber 3 is not too large and at the radial Walls of the vortex chamber 3 does not arise too much fiber friction, it is advantageous To increase the radius of the vortex chamber 3 over the prior art to at least one-tenth (advantageously more than one-sixth) of the effective staple length of the fibers to be processed (effective staple length calculated after the formula published in Japanese Utility Model 2,513,582).
- Friction reducing surface structure e.g., orange peel
- FIG. 3 shows, as a plan view (viewing direction A in FIG. 2), the wall plate 20 which closes off the vortex chamber 3 of FIG. 2 downstream against the discharge channel 7.
- the vortex direction is indicated by the arrows F.
- the openings 21 penetrate the wall plate 20 so skewed that the fluid swirling can flow into the discharge channel without great change in direction and thus generated turbulence.
- the wall plate 20 shown in plan-parallel in FIGS. 2 and 3 may also have the shape a preferably blunt cone, wherein the input opening 11, the Garnabzugkanals is arranged on the log of the cone.
- Figures 4 and 5 show in the same way as Figures 2 and 3, a further exemplary embodiment of the inventive device. Identical parts are designated by the same reference numerals as in FIGS. 2 and 3.
- Figures 4 and 5 differs by the embodiment the wall plate 20, the openings 21 are circumferentially arranged slots.
- the Discharge channel 7 is again shown with annular cross section, but could also another, suitably connected to the slot-shaped openings subsequent shape.
- Figures 6 and 7 show, in the same manner of representation as Figures 2 and 4, two further exemplary embodiments of the inventive device.
- a central part of the wall defining the vortex chamber downstream is formed by the input end face 30 of the Garnabzugkanals 5.
- a peripheral part adjoins this central part, the openings being arranged in the peripheral part (FIG. 6) or between the central and peripheral part (FIG. 7).
- Figure 6 shows an embodiment in which the vortex chamber 3 does not extend substantially plane and perpendicular to the axis of the Garnabzugkanals 5, as shown in Figures 2 and 4, but is conical.
- the central part of the vortex chamber 3 downstream bounding wall forms the Entrance-side end face 30 of Garnabzugkanals 5.
- One to the central part The peripheral part of this wall forms a perforated ring 31 Function of the discharge channel 7, for example, by the device surrounding airspace.
- FIG. 7 shows an embodiment in which the wall defining the vortex chamber 3 downstream is again formed by the input end face 30 of the yarn withdrawal channel 5 and a peripheral ring.
- the openings 21 to the discharge channel 7 together form a single, annular opening which is arranged between the central and peripheral wall part.
- the annular opening is as narrow as possible and as close as possible possible arranged at the inlet opening 11 of the Garnrabzugkanals 5.
