- Spinning machines in particular ring spinning machines, with pneumatic compression devices are known from the prior art.
- the pneumatic compression device serves the purpose of compressing a stretched fiber structure, wherein edge fibers protruding from the fiber structure by exerting an induced draft are guided towards the fiber structure and the fiber structure is generally compacted. Thanks to the pneumatic compaction process, a fine yarn of low hairiness can be produced.
- the suction insert is connected to a suction line, via which an induced by a vacuum source induced suction is applied.
- the compaction effect is achieved by ambient air through the openings in the outer circumference of the screen drum and the suction slot of the underlying suction insert is sucked into the suction line.
- Object of the present invention is therefore to propose a device by means of which a reduced or absent suction at the compression surface of the compacting device easily detected and can be corrected quickly, so that the quality of the yarn produced is impaired as little as possible.
- the suction device are associated with negative pressure indicating means for optically displaying a negative pressure or induced draft at the respective spinning station and thereby reduced compression suction power
- the negative pressure indicating means comprise a display element and return means acting on the display element, wherein the negative pressure the display element exerts a force, and the restoring means exert a negative pressure on the display element, and the negative pressure and the return means cooperate with each other such that when the negative pressure or the induced draft or when a negative pressure threshold or induced draft, the display element changes its shape due to the restoring force of the return means.
- the display means comprise a shape-changeable body on which a suction or negative pressure is exerted, which causes a change in the shape or the size of the body.
- the body or parts thereof have a resilience, which counteracts the induced draft or negative pressure, so that when the negative pressure or the induced draft decreases, the shape of the body is continuously or abruptly changed due to the restoring forces acting on the body.
- the body or parts thereof consists of a flexible material with resilience.
- the body is dimensionally stable under atmospheric pressure conditions and variable in its form or size when exerting a suction or negative pressure.
- the flexible material may, for. B. rubber-elastic or elastic properties have, which exert a counter to the negative pressure or the induced draft restoring force on the shape-changeable body.
- the display means include a variable-shape hollow body which is attached to the suction device, such that in its cavity an induced draft is exerted by means of which the shape or size of the hollow body is changed.
- the nature of the hollow body is such that when the negative pressure or the induced draft, the shape of the hollow body is changed due to the restoring forces acting on the hollow body.
- the change in shape is preferably in an expansion, bulging or unfolding of the hollow body walls, ie in an increase in the volume of the body due to the restoring forces acting on the body.
- the hollow body is preferably dimensionally stable under prevailing atmospheric pressure conditions inside and outside the hollow body.
- the hollow body is preferably in the form of a cylindrical bellows whose Faltenbalg Vietnamese has a resilience.
- the bellows folds together reducing its volume.
- the bellows unfolds under volume increase due to the acting restoring forces in Zylinderachsraum. In this way, a malfunction is visually displayed in the area of the compression area.
- the hollow body may also be a balloon-shaped body, the shell of which has a resilience, which counteracts the negative pressure or the induced draft, so that upon removal of the negative pressure or the induced draft, the balloon envelope unfolds or bulges outwards.
- the display element is in the form of a dome-shaped membrane which has a resilience counteracting the negative pressure or the induced draft, so that the membrane is everted when the pressure falls below a limit value for the negative pressure or for the induced draft ,
- the resilience is justified by an axial bias of the membrane.
- the membrane has at its triggered by changing the negative pressure or the induced draft change a Umspringtician or Umschlagtician ("mechanical dead center”), in which the membrane jumps from a concave shape into a convex shape.
- the membrane is designed and arranged on the suction device, that it is formed concave inward when the induced draft from the outside and absent or too low suction convex outwards. While an outside observer scarcely perceives the concave curvature of the membrane, it immediately catches the convexly outwardly convex membrane when the induced draft disappears.
- the perception can be enhanced by a coloring of the membrane by a striking signal color.
- the compacting device may include a rotatable compacting drum having a preferably annular cavity and a peripheral surface forming the compacting surface and provided with apertures.
- the suction device comprises a suction insert with suction opening, which is introduced into the cavity of the compression drum and stored therein stationary.
- the vacuum indicating means are mounted on the suction insert, wherein the display element is arranged laterally outside the compression drum.
- the compression device comprises a circumferential, perforated Verdichtungsriemchen whose peripheral surface forms the compression surface.
- the suction device comprises a stationary mounted suction insert with suction opening, over which the Verdichtungsriemchen is guided.
- the vacuum indicating means are mounted on the suction insert, wherein the display element is arranged laterally outside the circulation area of the compacting belt.
- the negative pressure indicating means are preferably arranged in a front end section of the suction insert, viewed in the direction of flow of the fiber structure.
- the invention further relates to a suction device for a pneumatic compression device of a spinning machine.
- the suction device comprises negative pressure indicating means for optically displaying a negative pressure or induced draft at the respective spinning station and thereby reduced compression suction power, the negative pressure indicating means including a display element and return means acting on the display element, the negative pressure acting on the display element exerts a force, and the restoring means exert a, the negative pressure opposing force on the display element, and the vacuum and the return means cooperate with each other such that upon decrease of the negative pressure or the induced draft or falls below a threshold value for the vacuum or induced draft, the display element changes its shape due to the restoring force of the return means.
- the spinning machine may be a ring spinning, funnel spinning, bell spinning or pot spinning machine.
- FIG. 1a shows a suction device 9 with a suction insert 1 and a subsequent to the suction insert 1 suction line 11 for a pneumatic compression device.
- the suction insert 1 has a suction slot 2 through which the air extracted from the compression area (not shown) (arrow 6) is removed. The air is fed through the suction insert 1 and the suction line 11 to a suction channel (arrow 7).
- vacuum indicating means 10 are mounted with a laterally arranged, cylindrical bellows 5.
- the bellows is connected via connecting means 3, 4 with the suction insert 1.
- the connecting means 3, 4 comprise an attachment 3, which is applied to the suction insert 1 and connected via a snap connection or adhesive bond thereto.
- the attachment 3 contains a connection interface 4, to which the bellows 5 is attached to the attachment 3.
- the attachment 3 is part of the vacuum indicating means 10.
- the connection interface 4 has a passage from the suction insert 1 to the display means 5 for the suction air 8.
- an attachment is dispensed with; instead, the attachment 3 and the connection interface 4 for the negative pressure display means 10 are integrated into the suction insert 1.
- FIG. 1b shows an arrangement according to FIG. 1a , in which, however, no or only a reduced negative pressure or induced draft in the suction insert 1 prevails.

- the lateral surface 90 is provided with openings 28a, 28b, through which the compression surface 27a, 27b is sucked.
- the suction insert 1 a, 1 b (dashed) is laterally inserted into an annular recess 91 in the screen drum 26 a, 26 b, wherein the lateral surface 90 forms the outer boundary of the annular recess.
- the suction insert 1 lies with its suction opening 2a, 2b directly under the lateral surface 90th
- the fiber bundle 29a, 29b to be compacted is conveyed in the fiber flow direction 17 out of the drafting system (not shown) through the nip line formed by the screen drum 26a, 26b and a drafting head top roller 25a, 25b onto the compacting surface 27a, 27b.
- the fiber bundle 29a, 29b to be compacted is guided onto the compacting surface 27a, 27b, compressed pneumatically and leaves the compacting device 21 via the rotational blocking gap formed by the rotary blocking roller 30a, 30b and the screening drum 26a, 26b in the direction of a swirl-producing member (not shown).
- the swirl-producing member causes the sliver to turn into a yarn. This happens with ring spinning machines z. Example by means of a ring-traveler system, which cooperates with a rotating spindle.
- the anti-rotation rollers 30a, 30b and delivery rollers 25a, 25b are supported in a known manner by a guide arm 22, 24 which supports the upper rollers 30a, 30b; 25a, 25b press on the underlying screening drum 26a, 26b.
- each spinning station output Drehsperrspalt in a known manner a Fadenabsaugrohr 31 a, 31 b assigned.

- the unfolded state of the bellows 5 a is triggered by the compression device 21 in the case of missing or defective suction power.
- FIG. 2 which is the compression device 21 in front view, ie from the perspective of the operator, can be seen, a poor suction at the spinning station immediately on the protruding bellows 5a recognizable.
- the bellows 5b is folded by the suction and therefore optically not or only badly noticeable.
- FIG. 2 Incidentally, on the embodiments according to the Figures 3 . 4 . 5 and 6 hold true.
- the embodiments according to the Figures 3 . 4 . 5 and 6 also show negative pressure indicating means 16, 49, 59, 79 with an attachment 13, 43, 53, 73 and corresponding connection interfaces 14, 44, 54, 74.
- the connection interfaces 14, 44, 54, 74 have passages from the suction insert (not shown) to the indicating element 15, 46, 55, 75 for the suction air 18, 48, 58, 78 on.
- the embodiment according to the FIGS. 3a, 3b comprises a balloon-shaped display element 15 with a flexible shell, which has a counteracting the induced draft recovery. Thanks to the resilience of the balloon body is in accordance with prevailing ambient pressure in its cavity in its unfolded size FIG. 3b in front. If an induced draft 18 is now created inside the balloon body 15, as happens during the compression process, a negative pressure arising in relation to the ambient pressure in the interior of the cavity causes the balloon wall to bulge inward or fold and the cavity to be reduced (FIG. Fig. 3a ). As soon as the induced draft disappears or is reduced, the balloon envelope folds or bulges due to the restoring forces, increasing the void volume and thus becomes visible to the operating personnel. The resilience is achieved here by flexible and possibly elastic embodiment of the balloon envelope.
- the balloon body 55, 55a, 55b according to Figure 5a-c arranged in a sleeve-shaped guide body 56 with a recess 57.
- the induced draft 18 inside the balloon body 55b causes the balloon wall to bulge inward and reduce the cavity (FIG. FIG. 5c ), so that the balloon body 55b is hardly or not visible in the recess.
- the balloon envelope 55a folds outward and outwardly enlarging the cavity volume and occupies the place in the recess 57 of the sleeve-shaped body 56.
- FIG. 5b ).
- the recess 57 and the sleeve body 56 is arranged at the spinning station or on the suction insert that the operator looks at the control of the spinning unit laterally to the recess 57, which then as a U, C or V-shaped recess on the sleeve body 56 is perceptible ( Figure 5b, 5c ).
- the recess may also be present as a laterally perceptible one-sided or continuous opening in the sleeve body, which is arranged so that the operator looks at them head-on (not shown).
- the embodiment according to the FIGS. 4a and 4b shows a freely movable in a cylindrical tube 45, spherical roller 46 according to the first embodiment.
- the cylindrical tube 45 is a closed hollow body, which is connected via a connection interface 44 and a cap 43 to the suction insert (not shown).
- the cavity of the cylindrical tube 45 and the suction insert are communicatively connected to each other via an air passage.
- the tube 45 may further have at its free end an air passage 47 to the atmospheric environment.
- the tube 45 rises from its free end to the connection interface 44, so that the sliding body 46 is inclined to roll down to the free end of the tube 45 due to the force of gravity acting on it.
- the roller 46 In trouble-free operation, however, the roller 46 is pulled towards the connection interface 44 by the induced against the force of gravity suction 48. However, if the induced draft 48 fails or falls below a certain threshold value, then the rolling element 46 shifts in the direction of the free end of the tube 45 and indicates in this way the presence of a compaction disturbance.
- the embodiment according to the Figures 6a and 6b shows a display element 75 in the form of a dome-shaped membrane, which is connected via a connection interface 74 and a cap 73 with a suction insert (not shown).
- the membrane 75 is flexible and separates the evacuated cavity of the absorbent insert from the atmospheric environment.
- the membrane 75 has a resilience, which makes them bulge outwards in atmospheric conditions on both sides. This resilience counteracts the induced draft 78, which pulls the membrane inwards toward the suction insert. Between these two positions, the membrane has a Umspringddling over which the membrane jumps from one layer to the other. If the induced draft 78 now stops or falls below a certain threshold value, then the membrane jumps outward and bulges accordingly. In this way, the spinning staff is notified of the presence of a compaction disturbance.
- FIG. 7 shows the screen drum 26a, 26b according to FIG. 2 in a side view.
- the sieve drum is open to the view side. This corresponds to FIG. 2 the to Loading arm 22, 24 facing side at the spinning station pairing.
- the vacuum display element 5a, 5b is arranged at this side opening at the lower end portion of the suction insert 1a, 1b and extends in unfolded or expanded state, ie in the presence of a compression disorder laterally outside the screen drum 26a, 26b.
- the suction line 11 is arranged at the upper end portion of the suction insert 1 a, 1 b.
