Description
Technical field
The special-shaped reed that the present invention relates to use in the air-jet loom specifically, relates to a kind of special-shaped reed of seeking the picking high speed when guaranteeing picking stability.
Prior art
Figure 27 is to use the weft insertion device of existing special-shaped reed.Be fixed with on the slay 1 and erect the special-shaped reed 2 that is provided with.Abnormity reed 2 is to arrange along the picking direction multi-disc reed wire 3 is set and constitutes.Each reed wire 3 is provided with the guide hole 4 that falls in, and this guide hole 4 forms a line and forms weft yarn passage T.Weft yarn Y with main burner 5 ejections flies in weft yarn passage T from picking.Guide hole 4, by the upper wall surface 4a of level, vertical internal face 4b, to the downward-sloping gradually lower wall surface 4c of the peristome 4f of guide hole 4 side, connect upper wall surface 4a and the curve form of internal face 4b upper corner 4d and, the lower corners 4e that is connected the curve form of internal face 4b and lower wall surface 4c forms.
In the front of slay 1, many pickings pilot jet 6 that separates the installation of set interval along weft yarn passage T is installed.Offer spray-hole 6a in picking with the top of pilot jet 6.From the injection main flow of spray-hole 6a ejection, shown in the arrow S of Figure 27, along the oblique ejection of weft yarn passage T.The two becomes one weft yarn passage T and special-shaped reed 2, is formed at the spray-hole 6a of picking with the top of pilot jet 6, extremely near weft yarn passage T.During picking, only picking with pilot jet 6 separately warp thread enter in the Warp opening, when beating up, only picking is extracted out to the below of warp thread in Warp opening with pilot jet 6.Picking is very thin with pilot jet 6, passes in and out at a high speed also and can not damage warp thread even picking separates warp thread with pilot jet 6.And picking uses the top of pilot jet 6 with respect to the distance that Warp opening passes in and out, and is less than the turnover distance of air ducting.Therefore, as make picking with pilot jet 6 in Warp opening and warp thread below between the structure that moves back and forth, compare with adopting air ducting, slay 1 has very little shaking quantity to get final product.Therefore, adopt the weft insertion device of special-shaped reed, open clear 55-93844 communique, spy with the spy and open the weft insertion device of clear 57-95344 communique, the disclosed employing air ducting of special public clear 59-26688 communique and compare, help realizing the high speed of air-jet loom.
But, use the weft insertion device of existing special-shaped reed 2 to exist following some problems.
The radius of curvature of the upper corner 4d of curve form and lower corners 4e from being convenient to use the forcing press stamped to consider, is about 2mm.In the weft insertion device that uses this special-shaped reed 2, the flight position of the weft yarn Y that flies in weft yarn passage T can change with the change of the impingement position of main flow S on the wall of guide hole 4 of the air draught of pilot jet 6 injections along with picking.
Relation when Figure 28 illustrates air main flow S1 bump upper wall surface 4a between the flight position Y1 of the dynamic change of peak flow rate (PFR) position and weft yarn Y, be the situation of seeing past tense from the upstream side of picking, Figure 31 illustrates the dynamic change of the air main flow S1 that sees past tense from the top.During air main flow S1 bump upper wall surface 4a, the dynamic change of air main flow S1 is behind the bump, advances to internal face 4b one side, changes direction downwards along upper corner 4d, flows to peristome 4f one side from internal face 4b afterwards.Because the peak flow rate (PFR) position as above changes, weft yarn Y is subjected at upper corner 4d place the influence of the air-flow of change direction downwards and flies near being shown in lower corners 4e as Y1.
Relation when Figure 29 illustrates air main flow S2 bump internal face 4b between the flight position Y2 of the dynamic change of peak flow rate (PFR) position and weft yarn Y, be the situation of seeing past tense from the upstream side of picking, Figure 32 illustrates the dynamic change of the air main flow S2 that sees past tense from the top.During air main flow S2 bump internal face 4b, bump back air main flow S2 advances along upper corner 4d, changes direction to peristome 4f one side.Because the peak flow rate (PFR) position as above changes, weft yarn Y be subjected to upwards changing at upper corner 4d place direction air-flow influence and fly near being shown in upper wall surface 4a as Y2.
Relation when Figure 30 illustrates air main flow S3 bump upper corner 4d between the flight position Y3 of the dynamic change of peak flow rate (PFR) position and weft yarn Y, be the situation of seeing past tense from the upstream side of picking, Figure 33 illustrates the dynamic change of the air main flow S3 that sees past tense from the top.During air main flow S3 bump upper corner 4d, the dynamic change of bump back air main flow S3 is, peristome 4f one side is partial on the limit of advancing downwards, limit slightly.Because the peak flow rate (PFR) position as above changes, weft yarn Y such as Y3 fly near being shown in upper corner 4d.
The flying speed of weft yarn and the flight stability of weft yarn have substantial connection with the flight position of weft yarn.In other words, the flying speed of weft yarn and the flight stability of weft yarn have substantial connection with air velocity distribution situation in the weft yarn passage.
When Figure 34 illustrates picking and is 80mm with the adjacent spaces X of pilot jet 6, the air velocity distribution situation in the weft yarn passage T of 80mm place, nozzle downstream.Single-point is scribed ss constant velocity line, and constant velocity line is to draw at interval with 10m/s.The position that indicates Vm is the peak flow rate (PFR) position.
As shown in figure 28, near flight position Y1, to composition that peristome 4f one side changed course is flowed a little less than, therefore, near the weft yarn Y that flies flight position Y1 can not fly out from weft yarn passage T, the flight stability of weft yarn Y.But,, therefore, lower in the flying speed of the weft yarn Y of flight position Y1 flight because near the air velocity the flight position Y1 of weft yarn Y is lower than peak flow rate (PFR).
Near the flight position Y2 of weft yarn Y air velocity approaches peak flow rate (PFR), and is higher in the flying speed of the weft yarn Y of flight position Y2 flight.But as shown in figure 29, near flight position Y2, the composition that flows to the changed course of peristome 4f one side is stronger, and therefore, near the weft yarn Y that flies flight position Y2 flies out from weft yarn passage T easily, and it is unstable that the flight of weft yarn Y becomes.
Near the flight position Y3 of weft yarn Y air velocity approaches peak flow rate (PFR), and is higher in the flying speed of the weft yarn Y of flight position Y3 flight.In addition, as shown in figure 30, near flight position Y3, to composition that peristome 4f one side changed course is flowed a little less than, therefore, near the weft yarn Y that flies flight position Y3 can not fly out from weft yarn passage T, the flight stability of weft yarn Y.
Therefore, realize at a high speed and stable flight, accomplish that picking sprays to upper corner 4d with the air main flow S of pilot jet 6 injections, near the weft yarn Y this point of flying upper corner 4d is very important.But, picking with pilot jet 6 with respect to the influence of the installation site of weft yarn passage T, picking with factors such as the injection pointing direction of the setting angle of pilot jet 6, spray-hole 6a, expulsion pressures under, the impingement position of air main flow on the guide hole wall can change.The flight position of aforementioned weft yarn Y will change with the change of the impingement position of air main flow S on the wall of guide hole 4 of pilot jet 6 injections along with picking.Therefore, for the weft insertion device that adopts existing special-shaped reed, but to make weft yarn Y in weft yarn passage T same position and to fly be difficult the position stability ground of high-speed flight.
Open flat 2-53935 communique, real opening in the flat 3-38378 communique the spy, disclose seek to realize weft yarn in special-shaped reed the high speed of flying speed in the formed weft yarn passage, prevent the device that weft yarn flies out from weft yarn passage.In these devices, the two angle of the upper wall surface of the guide hole of reed wire and internal face meets at right angles or acute angle, and the depression on the top of weft yarn passage is darker.Weft yarn passage is made the darker shape of depression on top, can make picking be difficult to spray to passage opening portion one side with the air-flow that pilot jet sprays.But, even if the situation of weft yarn in the upper corner stabilized flight that connects upper wall surface and internal face also can appear making in such passage shape.That is, the high speed of weft yarn flying speed with reduce because of weft yarn fly out flight failure that weft yarn passage produces the two can not take into account.
Open in the flat 8-74143 communique the spy, as shown in figure 35, the radius of curvature r of upper corner 8d that discloses a kind of special-shaped reed 7 is less than the weft insertion device of the radius of curvature R of lower corners 8e.Guide hole 8 is made the shape of the radius of curvature r of upper corner 8d less than the radius of curvature R of lower corners 8e, the air main flow that picking is sprayed with pilot jet 6 is difficult to behind the wall of bump guide hole 8 in upper corner 8d place change direction.Therefore, weft yarn is all the time in the high upper corner 8d stabilized flight of air velocity.
In addition, open in the flat 8-74143 communique the spy, also disclose a kind of like this form of implementation, promptly, except the radius of curvature r that reduces upper corner 8d, also reduced lower wall surface 8c from the extension size of internal face 8b with respect to the ratio of upper wall surface 8a from the extension size of internal face 8b.By reducing aforementioned proportion, can be with picking with the spray-hole 6a of pilot jet 6 near the configuration of weft yarn flight position, make the decay that is ejected into the air velocity on the wall of guide hole 8 from spray-hole 6a reduce.Therefore, the air velocity at the upper corner 8d place that weft yarn flew is higher, and weft yarn can high-speed flight.
This case applicant drives the special-shaped reed that discloses the used in jet loom of a kind of weft yarn high-speed flight more stably in the flat 11-140748 communique the spy.
But, exist the upper surface formation possibility of interference of the top ends of the upper wall surface 8a of abnormity reed when beating up to fabric.Upper wall surface 8a can damage fabric to the interference of fabric upper surface.Upper wall surface 8a interferes the problem of fabric, opens flat 2-53935 communique the spy, real opening in flat 3-38378 communique and the special special-shaped reed of opening flat 8-74143 communique etc. also exists.
Summary of the invention
The objective of the invention is, provide a kind of and avoid the interference between special-shaped reed and the fabric and can make weft yarn stable and with the used in jet loom abnormity reed of more speed flight in weft yarn passage.
For this reason, invention as scheme 1, the upper surface of guide hole and the radius of curvature of the upper corner between the internal face are less than the lower wall surface of said guide hole and the radius of curvature of the lower corners between the internal face, and the said upper corner side position of said upper surface is lower than the tip side position of said upper surface.
The air main flow that picking is sprayed with pilot jet sprays to upper corner from the below of peristome one side of weft yarn passage.But actual injection direction, because picking making and also existing discreteness during installation with pilot jet, thereby the situation of upper wall surface or internal face of spraying to is much.
Strike the air main flow on the upper wall surface, flow to internal face one side along upper wall surface.Radius of curvature is restricted the changed course of bump back air main flow less than the existence of the upper corner of the radius of curvature of lower corners, make to the air-flow of peristome one side changed course very a little less than.Therefore, the air main flow of bump upper wall surface, after bump, in the dynamic change of upper corner place, weft yarn is stabilized flight near upper corner.
Strike the air main flow on the internal face, flow to upper wall surface one side along internal face.Radius of curvature is less than the upper corner of the radius of curvature of lower corners, limited the changed course of bump back air main flow, make to the air-flow of peristome side changed course very a little less than.Therefore, the air main flow behind the bump internal face, in the dynamic change of upper corner place, weft yarn is stabilized flight near upper corner.
During air main flow bump upper corner, radius of curvature has limited the changed course of bump back air main flow less than the upper corner of the radius of curvature of lower corners, and the air main flow of bump upper corner is in the dynamic change of upper corner place.Therefore, near weft yarn stabilized flight upper corner.
The upper corner side position of making upper wall surface is lower than the structure of the tip side position of upper wall surface, and upper corner and picking are shortened with the distance between the pilot jet.The shortening of this distance improves upper corner place air velocity, and the flying speed of weft yarn improves.
The invention of scheme 2 is in scheme 1, constitutes said upper wall surface with horizontal wall surface with plane and the inclined wall with plane.
Form upper wall surface with planar combination, be convenient to make the upper corner side position of upper wall surface to be lower than the tip side position of upper wall surface.

Make the structure of radius of curvature below 1mm of upper corner, can increase the restriction effect of upper corner to the changed course of air main flow, the stability of collateral security weft yarn flight also is optimum.
The invention of scheme 4, be in scheme 1 to arbitrary claim of scheme 3, the length of said internal face be said upper wall surface length 40～60%.
If the position of upper wall surface is low excessively, the top ends of the upper wall surface of abnormity reed might produce the fabric upper surface and interfere when then beating up.Upper wall surface can damage fabric to the interference of fabric upper surface.The length of making internal face is 40～60% structure of the length of upper wall surface, the interference in the time of can avoiding beating up between upper wall surface and the fabric upper surface, and from the stable and high-speed flight that realizes weft yarn, also be optimum.
The invention of scheme 5, be in scheme 1 to arbitrary claim of scheme 4, the said lower wall surface of the said guide hole of at least a portion is of a size of said upper wall surface from 25%～55% of the extension size of said internal face from the extension of said internal face.
When the lower wall surface of guide hole from the extension size of said internal face less than said upper wall surface during from the extension size of said internal face, can make picking with the spray-hole of pilot jet near upper corner.So, the air velocity at upper corner place improves, and the flying speed of weft yarn improves.In this case, make lower wall surface and be of a size of 25%～55% the structure of upper wall surface, suit from picking stability and the high-speed flight that realizes weft yarn from the extension size of said internal face from the extension of internal face.The raising of air velocity helps to be reduced to and realizes desired weft yarn flying speed and the specific air consumption of needs.
The invention of scheme 6, be in scheme 1 to arbitrary claim of scheme 5, the wall of said upper wall surface, said upper corner, said internal face, said lower corners and said lower wall surface are provided with, to the inclined plane that weft yarn passage one side enters, the inclination angle on each inclined plane of the wall of said upper wall surface and said upper corner is greater than the inclination angle on the inclined plane of other wall towards the picking direction.
The inclination angle on inclined plane is big more, and the air mass flow of leaking between adjacent reed wire is few more.If can accomplish that the air mass flow of leaking is less at the wall place of upper wall surface and upper corner between adjacent reed wire, then the air velocity at upper corner place is improved.If can accomplish that air slowly leaks at the wall and the lower wall surface place of internal face, lower corners, then the air that flows out from the bottom of the peristome of weft yarn passage is reduced.The minimizing of the raising of upper corner place air velocity and the air that flows out from the bottom of the peristome of weft yarn passage, realize greater than the inclination angle on the inclined plane of other wall at the inclination angle on each inclined plane of wall that can be by making upper wall surface and front upper part bight.Therefore, weft yarn is stable more and with high-speed flight in upper corner.
The invention of scheme 7, be in scheme 6, the inclination angle on each inclined plane of the wall of said upper wall surface and said upper corner is 10 °～20 °, the inclination angle on the wall of said internal face, said lower corners and each inclined plane of said lower wall surface is 5 °～15 °, the inclination angle on the wall of said internal face, said lower corners and each inclined plane of said lower wall surface is less than the inclination angle on each inclined plane of the wall of said upper wall surface and said upper corner.
Make this structure, suit from high-speed flight and the stabilized flight that takes into account weft yarn.
The invention of scheme 8 is in arbitrary claim of scheme 6 and scheme 7, and two ends on each inclined plane of the wall of said upper wall surface, said upper corner, said internal face, said lower corners and said lower wall surface are chamfer shape.
Make this structure, the contact resistance in the time of can reducing warp thread and make harness motion between the end on warp thread and inclined plane improves the quality of fabric.
The invention of scheme 9 is in scheme 8, and said inclined plane is the straight line portion of flat shape except that the end of said chamfer shape, the width of said straight line portion on the thick direction of sheet of said reed wire be said reed wire sheet thick 0.4～0.8.
Make the structure with this size ratio, the raising of fabric quality and the high-speed flight of weft yarn suit when taking into account the loom high speed.

The working of an invention form
Below, in conjunction with Fig. 1～Figure 20 first form of implementation that the present invention specialized is described.The Unit Installation structure is identical with Figure 27, and in this form of implementation, adjacent picking is 80mm with the adjacent spaces X of pilot jet 6.
As depicted in figs. 1 and 2, constitute on the multi-disc reed wire 11 of special-shaped reed (tunnel reed) 10, be provided with " コ " font guide hole 12 that falls in, this guide hole 12 forms a line and forms weft yarn passage T.Guide hole 12, by the upper wall surface 12a of level, vertical internal face 12b, to the upper corner 12d between the downward-sloping gradually lower wall surface 12c that forms of the peristome 12f of guide hole 12 side, upper wall surface 12a and the internal face 12b and, lower corners 12e between internal face 12b and the lower wall surface 12c forms.Upper corner 12d and lower corners 12e are the arc surface shape.Upper wall surface 12a is 9mm from the extension size Wa of internal face 12b.The Wb of size up and down of internal face 12b is the 4.5mm of 50% degree of the extension size Wa of upper wall surface 12a, and lower wall surface 12c is from the extension size Wc of internal face 12b, is the 4mm of 45% degree of the extension size Wa of upper wall surface 12a.
If picking is provided with near weft yarn passage T simply with pilot jet 6, strengthen with its degree of crook of the warp thread Z between pilot jet 6 and the reed wire 11 with respect to the picking of coming in and going out in warp thread Z (shown in Figure 19) opening, warp thread Z can sustain damage.The damage of warp thread Z will cause fabric quality to reduce.Upper wall surface 12a to picking with the distance L up and down 1 of pilot jet 6 and, the top of the peristome 12f side of lower wall surface 12c is to the longitudinal separation L2 of spray-hole 6a, can not produce harmful effect to fabric quality with picking with pilot jet 6 is that prerequisite is set.
As shown in Figure 2, upper wall surface 12a is made of horizontal wall surface 12a1 and inclined wall 12a2.Horizontal wall surface 12a1 extends to the peristome 12f of weft yarn passage T side from internal face 12b.Inclined wall 12a2 has plane (with reference to Fig. 3).The plane of inclined wall 12a2 tilts with about 15 ° angle of elevation with respect to horizontal wall surface 12a1.Horizontal wall surface 12a1 is 5mm from the extension size Wa1 of internal face 12b.Inclined wall 12a2 is of a size of 4mm from the extension of horizontal wall surface 12a1.The position of horizontal wall surface 12a1 is than the low 1mm in the position of top 12g on the elongated surfaces on the plane of inclined wall 12a2, peristome 12f.Shown in Figure 2 is 1mm apart from Mh.
The radius of curvature r of the upper corner 12d of arc surface shape is 0.4mm, and the radius of curvature R of the lower corners 12e of arc surface shape is 2mm.
As Fig. 3～shown in Figure 7, upper wall surface 12a (promptly, horizontal wall surface 12a1 and inclined wall 12a2), internal face 12b, lower wall surface 12c, upper corner 12d and lower corners 12e, be towards the direction of picking shown in the arrow P enter (Ren り Write む to weft yarn passage T one side) the inclined plane form.The tiltangle a on the inclined plane of upper wall surface 12a and, the tiltangle d on the inclined plane of upper corner 12d, all be about 12 °.The tiltangle b on the inclined plane of internal face 12b and, the tiltangle e on the inclined plane of lower corners 12e, all be about 6 °.The tiltangle c on the inclined plane of lower wall surface 12c is about 7 °.
Two ends on each inclined plane of upper wall surface 12a, internal face 12b, lower wall surface 12c, upper corner 12d and lower corners 12e, for circular arc chamfered section 12r (with reference to Fig. 3～Fig. 7).The radius of curvature k of the chamfered section 12r of two ends on each inclined plane all is about 0.04mm.Radius of curvature k=0.04mm, be about reed wire 11 thickness t=0.2mm 20%.Each inclined plane is the straight line portion 12s (with reference to Fig. 3) of flat shape except that the chamfered section 12r of two ends, is u if establish the length of this straight line portion 12s, and then size is about 0.6 than u/t.
The air main flow S that picking is sprayed with pilot jet 6 sprays to upper corner 12d from the below of peristome 12f one side of weft yarn passage T.But, actual injection direction, because picking exists discreteness with pilot jet 6 when making and install, the situation that sprays to upper wall surface 12a or internal face 12b is much, also can spray to lower wall surface 12c sometimes.
As shown in Figure 8, be ejected into the air main flow Sa on the upper wall surface 12a, flow to internal face 12b one side along upper wall surface 12a.Radius of curvature r is the upper corner 12d of 0.4mm, the changed course of the air main flow Sa behind the restriction bump, the changed course air-flow that flows to peristome 12f one side very a little less than.Therefore, the air main flow Sa that is ejected on the upper wall surface 12a will be as shown in figure 11, near dynamic change upper corner 12d, near weft yarn Y stabilized flight upper corner 12d.
As shown in Figure 9, the air main flow Sb of bump internal face 12b flows to upper wall surface 12a one side along internal face 12b.Radius of curvature r is the upper corner 12d of 0.4mm, the changed course of the air main flow Sb behind the restriction bump, the changed course air-flow that flows to peristome 12f one side very a little less than.Therefore, the air main flow Sb of bump internal face 12b will be as shown in figure 12, near dynamic change upper corner 12d, near weft yarn Y stabilized flight upper corner 12d.
The air main flow of bump lower wall surface 12c flows to internal face 12b one side along lower wall surface 12c.Lower corners 12e with radius of curvature R bigger than the radius of curvature r of upper corner 12d helps to make the air main flow behind the bump to flow to upper corner 12d along internal face 12b.Therefore, the air main flow of bump lower wall surface 12c, near finally dynamic change upper corner 12d, near weft yarn Y stabilized flight upper corner 12d.
As shown in figure 10, when air main flow Sd bump upper corner 12d, radius of curvature r is the upper corner 12d of 0.4mm, the air main flow Sd changed course behind the restriction bump, the air main flow Sd of bump upper corner 12d, near dynamic change upper corner 12d.Therefore, the air main flow Sd of bump upper corner 12d will be as shown in figure 12, near dynamic change upper corner 12d, near weft yarn Y stabilized flight upper corner 12d.
Can obtain following effect by first form of implementation.
(1-1) flight stability of the flying speed of weft yarn Y and weft yarn Y has substantial connection with the flight position of weft yarn Y.In other words, the flying speed of weft yarn Y and the flight stability of weft yarn have substantial connection with air velocity distribution situation in the weft yarn passage T, so that weft yarn Y flies near the upper corner 12d of peak flow rate (PFR) position to best.The special-shaped reed 10 of Fig. 2 with upper corner 12d of radius of curvature r=0.4mm, no matter picking impinges upon on which wall of guide hole 12 with the air main flow S that pilot jet 6 sprays, and weft yarn Y all is limited in upper corner 12d flight.The existing apparatus that near its result, weft yarn Y bit as the upper corner 12d of peak flow rate (PFR) position is opened flat 8-74143 communique more stably flies.
(1-2) position of the horizontal wall surface 12a1 of formation upper wall surface 12a, Mh=1mm is hanged down in the position of the top 12g of the 12f of ratio open portion.That is, the upper corner 12d side position of upper wall surface 12a is lower than the tip side position of upper wall surface 12a, and near the position of the upper wall surface 12a part the upper corner 12d is lower than near the position of the upper wall surface 12a part the 12g of top.The position of upper corner 12d is also lower than the position of horizontal wall surface 12a1.Therefore, upper corner 12d and picking are shortened with the distance between the spray-hole 6a of pilot jet 6, and near the air velocity the upper corner 12d improves.Near its result, weft yarn Y bit as the upper corner 12d of peak flow rate (PFR) position is opened the existing apparatus of flat 11-140748 communique with higher speed flight.
The curve G0 of Figure 14 illustrates under the situation of the special-shaped reed 10 that uses Fig. 2 the air velocity at 12d place, weft yarn passage T internal upper part bight.Transverse axis represents that picking usefulness pilot jet 6 is to the distance between the picking direction.Curve G1 illustrates and uses special opening under the situation of the disclosed special-shaped reed of flat 11-140748 communique, the air velocity at place, weft yarn passage T internal upper part bight.Curve G2 illustrates under the situation of the special-shaped reed 7 that uses Figure 35 the air velocity at 8d place, weft yarn passage T internal upper part bight.Curve G3 illustrates under the situation of using special-shaped reed 2 air velocity at 4d place, weft yarn passage T internal upper part bight.Horizontal wall surface 12a1 is lower than the special-shaped reed 10 of inclined wall 12a2, drives the disclosed special-shaped reed of flat 11-140478 communique with the spy and compares, and the air velocity at its upper corner 12d place improves comprehensively.
(1-3) flow to the part of the air draught of picking direction P one side, from leaking between the adjacent reed wire 11.The ratio of this leakage is big more, and the flow velocity of air draught that flows to picking direction P one side is low more, and the flying speed of weft yarn Y is low more.Formed inclined plane on the wall of guide hole 12 is to be used for suppressing air from the leakage between the reed wire 11, and this inclined plane helps weft yarn Y with high-speed flight.The tiltangle d on the tiltangle a on the inclined plane of upper wall surface 12a and the inclined plane of upper corner 12d, the big degree that arrives to the twice of the tiltangle b on other inclined plane, θ c, θ e.Therefore, from the air main flow S that the picking of peristome 12f one side-lower is sprayed towards bight, top 12d with pilot jet 6, its ratio in upper wall surface 12a and the leakage of upper corner 12d place is inhibited.Its result can be reduced to the specific air consumption that realizes desired weft yarn flying speed and need and can not influence the high-speed flight of weft yarn Y.
And high-speed flight and stabilized flight in order to take into account weft yarn, preferably, the scope of tiltangle a, θ d is 10 °～20 °, the scope of tiltangle b, θ c, θ e is 5 °～15 °, and tiltangle a, θ d are greater than tiltangle b, θ c, θ e.
(1-4) wall except that upper wall surface 12a and upper corner 12d, promptly the tiltangle b on each inclined plane of internal face 12b, lower wall surface 12c and lower corners 12e, θ c, θ e are identical with the inclined degree of existing special-shaped reed.Because tiltangle b, θ c, θ e are less than tiltangle a, θ d, therefore, air slowly leaks between reed wire 11 at internal face 12b, lower wall surface 12c and lower corners 12e place.This case inventor has carried out the contrast experiment to tiltangle a, θ d greater than special-shaped reed and the special flight stability of opening the existing apparatus of flat 8-74143 communique of tiltangle b, θ c, θ e.Confirm that by experimental result this case inventor open the existing apparatus of flat 8-74143 communique with the spy and compare, tiltangle a, θ d can make the flight of weft yarn more stable greater than the special-shaped reed of tiltangle b, θ c, θ e.
(1-5) curve H1, H2, the H3 of Figure 15 are the data that concern between the flying speed of the extension size Wc of the reflection lower wall surface 12c that obtains by experiment and weft yarn Y.Experimental data when curve H1 is to use the special-shaped reed 10 of Fig. 2.Experimental data when curve H2 is to use the special-shaped reed 7 of Figure 35, the experimental data when curve H3 is to use the special-shaped reed 2 of Figure 27.Curve I1, the I2 of Figure 15, I3 are the data that concern between the flight failure generation frequency of the extension size Wc of the reflection lower wall surface 12c that obtains by experiment and weft yarn Y.Experimental data when curve I1 is to use the special-shaped reed 10 of Fig. 2.Experimental data when curve I2 is to use the special-shaped reed 7 of Figure 35, the experimental data when curve I3 is to use the special-shaped reed 2 of Figure 27.
The flight failure of so-called weft yarn Y, terminal with no show picking in the allowed time as assert standard.In these experiments, upper wall surface is fixed from the extension size of internal face.In addition, the top of lower wall surface to the distance L 2 of spray-hole 6a is fixed, and picking sprays to upper corner all the time with the air main flow S that pilot jet 6 sprays.And picking is also fixed with the air mass flow that pilot jet 6 sprays.
By curve H1, H2 and curve I1, I2 as can be known, as special-shaped reed 10 and special-shaped reed 7,, can when not increasing, improve weft yarn Y flight failure generation frequency the flying speed of weft yarn Y along with reducing of the extension size Wc of lower wall surface 12c, 8c.Extension size Wc as lower wall surface 12c is this form of implementation of 4mm, is that the spy of 7mm drives the disclosed special-shaped reed 7 of flat 8-74143 communique and compares with the extension size Wc of lower wall surface 8c, and it is high that the flying speed of weft yarn is wanted.But, be reduced to below the 2mm if extend size Wc, then the air-flow diffusion inhibit feature that had of the weft yarn passage T that is formed by upper wall surface 12a, internal face 12b and lower wall surface 12c weakens, and can't realize air velocity evenly distribution in weft yarn passage T.When being in this situation, the weft yarn flying speed begins to reduce, and also will increase because of fly out from the weft yarn passage T generation frequency of the weft yarn flight failure that takes place of weft yarn Y.Can judge that from the experimental data of Figure 15 the extension size Wc of lower wall surface 12c is to be advisable in 25%～55% the scope of the extension size Wa of upper wall surface 12a.
(1-6) the curve E of curve map shown in Figure 16 is the experimental data that concerns between the radius of curvature r of reflection upper corner 12d and the weft yarn flight failure frequency.This experiment is to be that No. 40 cotton threads of standard, loom rotating speed are to carry out under the certain condition of 900rpm, air mass flow at weft yarn.The degree of the radius of curvature that as long as the radius of curvature r of upper corner 12d below 1mm, just can make the flight failure frequency reduce to uses upper corner 4d 1/5 during as the special-shaped reed 2 2mm degree, Figure 27.
(1-7) upper wall surface 12a is a kind of like this shape of inclined wall 12a2 that the horizontal wall surface 12a1 that links to each other with upper corner 12d is lower than top 12g one side of peristome 12f, employing be the structure that the height dimension of internal face 12b is diminished.Curve M 1 in the curve map of Figure 17, be reflection internal face 12b height dimension Wb with respect to the size of the extension size Wa of upper wall surface 12a than Wb/Wa, and, the experimental data that concerns between the weft yarn flying speed.Curve N 1 in the curve map of Figure 17 is that the reflection size is than the experimental data that concerns between Wb/Wa and the weft yarn flight failure generation frequency.
The weft yarn flying speed is the fastest when size is 0.4 degree than Wb/Wa.When size is littler to 0.25 when following than Wb/Wa, the weft yarn flying speed sharply reduces.This be because, the height dimension Wb of internal face 12b diminishes thereby picking impinges upon on upper wall surface 12a and the lower wall surface 12c with the air jet of pilot jet 6 injections, the cause that the leakage of air between reed wire 11 increases at upper wall surface 12a and lower wall surface 12c place.What upper wall surface 12a and lower wall surface 12c place air leaked increases, and will cause near the air velocity of upper corner 12d to reduce, and the weft yarn flying speed sharply reduces.In addition, when size than Wb/Wa less than 0.4 the time, it is too small that the area of guide hole 12 will become, the weft yarn flight failure increases.Therefore, size is being advisable more than 0.4 than Wb/Wa.But, in size than Wb/Wa greater than 0.4 zone, along with the increase weft yarn flying speed step-down of this ratio.Therefore, consider that from weft yarn flying speed and two aspects of weft yarn flight failure size is advisable with 0.4～0.6 than Wb/Wa.
On the other hand, if size than Wb/Wa less than 0.4, then as shown in figure 19, interfere the quality reduction of fabric when beating up between the upper surface of upper wall surface 12a and the fabric W of abnormity reed 10.Consider that from the angle of avoiding fabric quality to reduce size equally also is to be advisable with 0.4～0.6 than Wb/Wa.
(1-7) curve M 2 in the curve map of Figure 18, be between the top 12g of reflection horizontal wall surface 12a1 and peristome 12f up and down apart from Mh with the experimental data that concerns between the weft yarn flying speed.Curve N 2 in the curve map of Figure 18 is that reflection is apart from the experimental data that concerns between Mh and the weft yarn flight failure generation frequency.
Along with distance Mh increases gradually from 0, upper corner 12d and picking are with the two distance shortening of the spray-hole 6a of pilot jet 6.Therefore, the air velocity at upper corner 12d place improves, and the flying speed of weft yarn Y improves.The weft yarn flying speed is the fastest when distance Mh=1.2mm degree, is increased to 2.5mm when above apart from Mh, and the weft yarn flying speed sharply reduces.This be because, picking impinges upon on upper wall surface 12a and the lower wall surface 12c with the air jet of pilot jet 6 injections thereby the height dimension Wb of internal face 12b diminishes, the cause that the leakage of air between reed wire 11 increases at upper wall surface 12a and lower wall surface 12c place.What upper wall surface 12a and lower wall surface 12c place air leaked increases, and will cause near the air velocity of upper corner 12d to reduce, and the weft yarn flying speed sharply reduces.In addition, when distance Mh is increased to 1.5mm when above, it is too small that the area of guide hole 12 will become, and the weft yarn flight failure increases.Therefore, be advisable with 0mm～1.5mm apart from Mh.
On the other hand, if apart from Mh greater than 1.5mm, then as shown in figure 19, interfere the quality reduction of fabric when beating up between the upper surface of upper wall surface 12a and the fabric W of abnormity reed 10.Considering from the angle of avoiding fabric quality to reduce, equally also is to be advisable with 0mm～1.5mm apart from Mh.
(1-8) chamfered section 12r in the arc-shaped is in two ends on each inclined plane of upper wall surface 12a, internal face 12b, lower wall surface 12c, upper corner 12d and lower corners 12e.Curve J in the curve map of Figure 20 is reflection thick t of sheet of reed wire 11 and straight line portion 12s the width u on the thick direction of sheet of reed wire 11 the two size than u/t, and, the experimental data that concerns between the weft yarn flying speed.If size is more than 0.4 than u/t, then the weft yarn flying speed can keep very high speed.But the two ends of the fabric W on the loom and picking be with near the warp thread Z the pilot jet 6, do not parallel with reed wire 11 and inclination arranged slightly.Therefore, if size than u/t greater than 0.8, the increase of contact resistance when then warp thread is made harness motion between warp thread Z and the chamfered section 12r will damage warp thread Z and reduces fabric quality.The warp thread Z that intensity is relatively poor also can be broken sometimes.Therefore, size than u/t in 0.4～0.8 scope, to be advisable.

As shown in figure 22, the upper wall surface 12a of guide hole 12 is 10mm from the extension size Wa of internal face 12b, and the Wb of size up and down of internal face 12b is 4mm.From picking with the upstream side of the tube hub alignment weft yarn passage T of pilot jet 6 at a distance of the position of 3mm, with, side apart between the position of 15mm downstream, what use is to extend the reed wire 11 of size Wc as 4mm, and what use on the position in addition is to extend the reed wire 11A of size Wc1 as 7mm.Reed wire 11 is identical with first form of implementation with distance L 1, L2 and other structure of the spray-hole 6a of pilot jet 6 to picking.And picking is same with the air main flow S and first form of implementation that pilot jet 6 sprays, sprays to upper corner 12d.
