Definitions
- the invention relates to a series shed weaving machine a weaving rotor with insert and stop combs is equipped with the insertion combs on his Peripheral warp threads from an insertion station to combed a stroke in the form of compartments while in the subjects weft threads from a weft preparation be fed, and the with the combs registered shots at the stop of the educated Tissue strikes.
- a row shed weaving machine with a weaving rotor is in the EP-A-0 012 253.
- For row shed weaving machines As with weaving machines, there is generally the problem of Flight that collects in inappropriate places and from which should be woven in as little as possible. There with the compartments in the form of themselves crossing warp threads are combed and this Warp threads under tension on the individual combs be deflected while the weft threads are inserted there is flight and heat in the bullet area between insertion station and stop.
- Patent application EP-A-0 580 028 discloses using the example a spinning machine a tubular work space for Textile machines in which ambient air is blown that is on the machine from the installation room was sucked in and conditioned to a Conditioning of the entire installation room dispense and the used air to the outside to lead.
- the disadvantage of such an arrangement is that they only solve the problem of the resulting flight to a limited extent can, since the flight is in all possible corners, niches and stops dreaming.
- This task is solved in that the weaving rotor in the Area of the combs in a circumferential direction from the Insertion station up to the stop by a a cover forming an annular channel is covered and that suction nozzles are attached along the stop edge introduced air together with the resulting flight from the Vacuum the ring channel.
- the examples on the web rotor show one Row shed a cover that matches the Web rotor in the circumferential direction from a loading station up to the tissue stop forms an annular channel, which in the circumferential direction and on the front at the The arrival of the shot is closed by additional covers.
- Suction nozzles are attached along the stop edge are dimensioned such that, despite the air intake from Bullet and relay nozzles one negative pressure and one Generate flow from the loading station to the stop, which prevents flight from being discontinued.
- a Additional suction nozzle when the shot arrives in Weft direction is arranged, additionally stabilized the flow conditions in the ring channel.
- the externally visible elements are one Web rotor 2 shown, which is equipped with rows of combs 3 is, each of an insertion comb 4 and a Stop comb 5 exist.
- the weaving rotor 2 turns in Direction of rotation 20 about its axis 38 and dips with his Comb 4, 5 into the warp threads 7 at an insertion station 6 one, which of a series of insertion rails 10 in the Combs are distributed.
- the parallel to the ridges running insertion rails are at intervals narrow lying between the warp threads 7
- Guide elements 9 guided, which in turn on support arms 8 are supported on the frame of the weaving machine.
- Combs 4, 5 comb the warp threads from the loading station 6 to Stop edge 13 in the form of moving subjects 21 through.
- the stop combs 5 push the shots 12 to the End of the compartment and stop at stop 13, which already created tissue 14 by a support beam 15 and a spreader 16 deflecting under pretension is fixed.
- the spreader 16 is in turn through a longitudinal spar 17 supported, which also a cover plate 26 carries while the forces on the support beam 15 and a deflection 18 via arms 19 to the machine frame are intercepted.
- a cover 22 which as independently removable cover 30 is executed an annular channel 23 from the insertion station 6 to Stop 13 generated together with the weaving rotor, which on Stop 13 through the cover plate 26 and on the side of Arrival of the shot is completed with an end wall 33.
- the additional nozzle 34 is behind a recess in the end wall 33 connected to the cover 30 attached and has a collar with which the rest the recess is covered.
- the additional suction nozzle 34 is regardless of the cover 30 on the spar 17 with a bracket 39 attached.
- the ring channel 23 At the end of the row of ridges 3 is the ring channel 23 by a larger one because of the missing rows of combs annular channel 32 continued up to the end wall 33, for additional devices such as one in cutting and stretching device indicated in its outlines 40 and to install a shotguard.
- the suction nozzles 24 open directly into the suction pipe 28.
- the suction pipe 28 itself is at the level of the end wall 33 with a Closed floor and leads the air against the Direction of entry. This allows behind the Front wall 33 in the cover 30 space for further elements to be provided without impairing removal from the flight.
- Figure 1 adjoins the support beam 15 in a circumferential manner
- Direction 20 on a cover 36 the apron 37 on the support arms 8 rests and up to the insertion rails 10 is enough.
- the movable part of the apron 37 consists of a 2 mm thick Teflon film, which with appropriate Brush the negative pressure on the inside of the comb tips can. With this measure, the resulting flight largely encapsulated. There can be no flight accumulations arise that interfere with the insertion on the combs and the Flight can largely be disposed of with the suction stream. For example, in a row shed weaving machine on 1 million rounds of 400 grams of flight found that too more than 200 grams are removed and disposed of could while a comparable projectile loom had more flight that could not be removed.
- FIG 4 the air budget is schematic and partial summarized in processing.
- the ring channel 23 and the annular channel 32 are dashed on the weaving rotor 2 indicated.
- On the left Front side of the weaving rotor 2 are a drive motor 48 and a gear 49 indicated.
- Bullet nozzles 50 that with rotate with the weaving rotor 2 are over a stationary Part with compressed air 53 and with weft threads (not here shown) supplied from a weft processing.
- the Ring channels 23, 32 are at the top except for the suction nozzles 24 closed, which closer distances in the firing direction to each other to grow To achieve suction cross section.
- the right end wall 33 closes except for the additional suction nozzle 34 annular channel 32 also from.
- the suction power the suction nozzles should be so high that none Backflow occurs in the ring channel 23, but rather still Air 41 is drawn in from the environment to create a flow in the suction direction 25 along a helix produce.
- the flight is with the air from the suction pipe 28 and the Additional suction nozzle 34 from a suction fan 42 via a Filter 44 sucked.
- a weft conveyor 11 is encapsulated by a housing 46 so that about the same Suction fan 42 outside air 41 at such a high speed sucked through the weft conveyor is that the flight via a feed line 47 also to the Filter 44 is supplied. From the filter 44 takes place in flight disposal 45 takes place at larger time intervals.
- a row shed weaving machine With an installed capacity of around 8 kilowatts a row shed weaving machine becomes 1 Kilowatts for a merchandise tree drive and one Warp reduction consumed while the heat portion of the remaining power, which is made up of about 1.2 Kilowatts for the suction fans 42, 43 and maybe against 5 kilowatts for motor 48, for shot preparation 11 and for control including inlay work, largely from the Atmosphere of the installation room can be kept away.
