Definitions
- the invention relates to a row shed weaving machine with a weaving rotor which is equipped with insert and stop combs, which combs warp threads from an insertion station to a stop in the form of compartments with the insert combs on its periphery, while weft threads from a weft thread preparation are fed into the compartments , and strikes the registered shots with the stop combs on the stop of the tissue formed.
- EP-A-0 580 028 discloses, using the example of a spinning machine, a tubular work space for textile machines, in which ambient air is blown in, which on the machine from the installation space was sucked in and conditioned in order to avoid conditioning the entire installation room and to lead the used air outside.
- the disadvantage of such an arrangement is that it can only solve the problem of the flight involved to a limited extent, since the flight settles in all possible corners, niches and dead spaces.
- This object is achieved in that the weaving rotor in the area of the combs is covered in the circumferential direction from the insertion station up to the stop by a cover forming an annular channel and that suction nozzles are attached along the stop edge, the air introduced together with the resulting flight from the Vacuum the ring channel.
- the advantage of this arrangement is that a negative pressure and a strong air flow in the direction of rotation is formed in the ring channel thus generated, which is further reinforced by the movement of the rows of combs in the direction of rotation. Flight that occurs when combing through the compartments is caused by the impulses of bullet nozzles and wandering fields, by the suction effect in the ring channel and by the slight centrifugation in the rotating flow in the Ring channel brought, the impact of the impact of the weft threads still reduce friction at the points of contact with the flight.
- the ring channel outside the combs is continued as an annular channel with an end wall sealed to the weaving rotor and in the area of the weft arrival an additional suction nozzle is attached in the end wall, which at the same time stretches the weft tip.
- This has the advantage that the suction flow and flight perform a helical movement, while the entry side on the ring channel can remain open.
- it is advantageous to streamline the elements not shown here, such as the weft guard and cutting and stretching device, in the direction of rotation in the annular channel at the arrival of the weft so that no accumulations of flight can occur.
- Rotation of the combs already prevents a build up of flight.
- An apron that can easily rub in the direction of rotation not only reduces the distance to a minimum, but also acts as long-term lubrication for the comb tips, if it is made of Teflon, for example. Due to the fact that the flight-generating areas are under negative pressure and an air stream is continuously sucked out of this negative pressure area by a suction fan, a large proportion of the flight can be captured and disposed of in the air stream via a filter.
- Figure 1 schematically shows a part of a section transverse to the axis of a weaving rotor on a row shed loom, a removable cover with the weaving rotor forming an annular channel between the insertion station and the stop;
- Fig. 3 schematically shows a section through a row shed weaving machine transverse to the axis of the
- Row shed weaving machine with a weaving rotor which has an annular channel with suction nozzles.
- the examples show a cover on the weaving rotor of a row shed weaving machine, which is connected to the
- Weft direction is arranged, additionally stabilizes the flow conditions in the ring channel.
- FIG. 1 shows the externally visible elements of a weaving rotor 2 which is equipped with rows of combs 3, each of which consists of an insertion comb 4 and a stop comb 5.
- the weaving rotor 2 rotates in the direction of rotation 20 about its axis 38 and dips its combs 4, 5 into the warp threads 7 at an insertion station 6, which are distributed into the combs by a series of insertion rails 10.
- the insertion rails running parallel to the combs are guided at intervals by narrow guide elements 9 lying between the warp threads 7, which are in turn supported on the frame of the weaving machine via support arms 8.
- the combs 4, 5 comb through the warp threads from the insertion station 6 to the stop edge 13 in the form of moving compartments 21.
- the stop combs 5 push the shots 12 to the
- the fabric 14 already formed being fixed by a support beam 15 and a spreader 16 deflecting under pretension.
- the spreader 16 is in turn supported by a longitudinal beam 17, which also carries a cover plate 26, while the forces on the support beam 15 and on a deflection 18 are intercepted via arms 19 to the machine frame.
- a cover 22 which is designed as an independently removable cover 30, an annular channel 23 from the insertion station 6 to
- Stop 13 generated together with the weaving rotor, which is closed at the stop 13 by the cover plate 26 and on the side of the weft arrival with an end wall 33.
- suction nozzles 24 are attached along the stop edge 13 in the cover 22, which open into a suction pipe 28 located behind them and are dimensioned such that ambient air 41 flows into the annular duct 23 at the insertion station 6. It is worth keeping the distance 27 of the cover 22 to the highest comb tips small in order to be able to dimension the suction power smaller. If, for example, a sufficient flow in the suction direction 25 is generated for a specific arrangement of the suction nozzles 24 at a distance 27 of 8 mm, this is insufficient if the distance is doubled and a distance 27 of more than 25 mm over the length of the weaving rotor no longer allows safe flight disposal.
- an additional suction nozzle 34 is arranged in the weft direction in the end wall 33, which has a shape distorted in the direction of rotation in order to catch the weft thread tips arriving with the traveling field 51 in order to discharge the air impulses from the weft insertion without deflection from the ring channel 23 and around it Stretch the shot at its tip under tension for a possible clamping and cutting process.
- the additional nozzle 34 is arranged behind a recess in the end wall 33 connected to the cover 30 and has a collar with which the rest of the recess is covered.
- the additional suction nozzle 34 is attached to the spar 17 with a bracket 39 independently of the cover 30.
- the annular channel 23 is continued through an annular channel 32, which is larger because of the missing rows of combs, up to the end wall 33, in order to attach additional devices such as a cutting and stretching device 40 and shot guard indicated in its contours.
- the suction nozzles 24 open directly into the suction pipe 28.
- the suction pipe 28 itself is closed off at the level of the end wall 33 with a floor and discharges the air against the direction of entry. This makes it possible to provide space for further elements in the cover 30 behind the end wall 33 without impairing removal from the flight.
- a cover 36 adjoins the support beam 15 in the circumferential direction 20, which lies as an apron 37 on the support arms 8 and extends as far as the insertion rails 10.
- the movable part of the apron 37 consists of a 2 mm thick Teflon film, which can graze the inside of the comb with a corresponding negative pressure on the inside. With this measure, the resulting flight is largely encapsulated. There can be no accumulations of flight that interfere with the insertion on the combs and the flight can largely be disposed of with the suction stream. For example, a row shed loom found 400 grams of flight per million weft, which could be removed and disposed of more than 200 grams, while a comparable projectile weaving machine had more flight that could not be removed.
- FIG 4 the air budget is summarized schematically and partially in processing.
- the annular channel 23 and the annular channel 32 are indicated by dashed lines on the weaving rotor 2.
- a compressed air supply 52 for relay nozzles is listed on the right-hand end side, which produces moving fields 51 on a helical line in the area of the ring channel 23 in the subjects not shown here.
- a drive motor 48 and a gear 49 are indicated on the left end face of the weaving rotor 2.
- Bullet nozzles 50 which also rotate with the weaving rotor 2, are compressed with compressed air 53 and with weft threads (not here in this case) shown) supplied from a weft processing.
- the ring channels 23, 32 are closed at the top except for the suction nozzles 24, which are closer to one another in the weft direction in order to achieve a growing suction cross section.
- the right end wall 33 also closes the annular channel 32 except for the additional suction nozzle 34.
- the suction power of the suction nozzles should be so high that no backflow occurs in the ring channel 23, but rather air 41 is drawn in from the surroundings in order to generate a flow in the suction direction 25 along a helical line.
- the flight is drawn off with the air from the suction pipe 28 and the additional suction nozzle 34 by a suction fan 42 via a filter 44.
- a weft conveyor 11 is encapsulated by a housing 46 in such a way that outside air 41 is drawn in through the weft conveyor at such a high speed via the same suction blower 42 that the flight is likewise fed to the filter 44 via a feed line 47.
- a flight disposal 45 takes place from the filter 44 at larger time intervals.
- FIG. 3 shows the run of the warp threads 7, which run from a warp beam 60 via deflections 18 to the insertion station
- Conditioned air 62 is brought into an air conditioning duct 59 via a feed line 58 and its speed is slowed down.
- the conditioned air passes through many small openings and, because of the pressure difference across the openings, is distributed uniformly into a chamber 64 which is formed by side plates 61 and the warp beam 60.
- the chamber 64 is covered by the relatively close-lying warp threads 7, through which the conditioned air must pass uniformly at low speed and reach the atmosphere from the installation room.
- Such an arrangement has proven to be a fairly economical solution for conditioning the warp threads.
- the relatively large length of the exposed warp threads 7, which are exposed to the conditioned air between the warp beam 60 and the weaving rotor 2 the exposure time for the conditioning is sufficient even with high numbers of wefts.
