Description
Technical field
The present invention relates to the Weft insertion nozzle of water-jet loom.
Background technology
In order to cut down the diffusion of the press water that sprays from Weft insertion nozzle, the example that has Patent Document 1～3 as described later to enumerate: begin the shape of each several parts such as pin or nozzle body is improved repeatedly from rectification part.The Weft insertion nozzle of water-jet loom is provided with: formed the pin that makes the thread guide eyelet that weft yarn passes through, be formed for inserting the hollow bulb of pin and have with outer peripheral face between the inner peripheral surface of the nozzle body of giving the water hole, outer peripheral face by pin and the nozzle body that the are communicated with annular chamber of delimiting, and, adjust the formations such as rectification part that flow of the press water of injection by the nozzle body inside of packing into, the position between annular chamber and spray-hole.
Rectification part inside is provided with the rectifying ribs of a plurality of compartment of terrains in a circumferential direction configuration, has a plurality of rectifier tanks of delimiting by the rectifying ribs of adjacency.Press water is supplied to via water-conveying channel from the pump of outside, flows into the annular chamber that is formed between pin and the nozzle body from the outer peripheral face of nozzle body, and then by behind the rectification part, introduces the weft yarn that is positioned at the pin leading section and in the opening picking of warp thread.
Because worry diffusion owing to the jet water course that ejects from Weft insertion nozzle, and strike on the warp thread and cause damage weaving cotton cloth, so require the press water in the Weft insertion nozzle to have high rectilinear propagation, but be strong turbulent flow and have multiple speed composition because flow into the press water of Weft insertion nozzle, diffusion after these factors can promote to spray is so need certain countermeasure.With annular chamber in abutting connection with the rectification part of configuration in order to adjust flowing of press water, and be set side by side with a plurality of rectifying ribs that on the radial direction of nozzle-axis direction and nozzle-axis direction, extend in the circumferencial direction compartment of terrain, the rectifier tank that press water constitutes by the rectifying ribs by adjacency is removed the turbulent flow composition thus.Such rectification part is provided for improving the rectilinear propagation of jet water course.Relative with it, the Weft insertion nozzle of the water-jet loom of record has Patent Document 1～3 described pin, nozzle body and rectifying ribs in Patent Document 4, at the Weft insertion nozzle of same water-jet loom, be formed on the eccentric direction in the center (axis) of relative nozzle with rectifier tank that the rectifying ribs of interior all adjacency of nozzle body delimited.

Patent Document 3: the spy opens flat 10-130997 communique (Fig. 2)
Patent Document 4: the spy opens flat 4-11048 communique (Fig. 6, Fig. 7)
; because rectifying ribs in the technology of any of these Patent Documents 1～3 or rectifier tank all form along the nozzle-axis direction; press water by each rectifier tank converges because of bumping against on one side with pin periphery fierceness on one side, so have the bigger problem of diffusion of the jet water course after turbulization or the injection.In addition, if technology according to Patent Document 4, because the relative nozzle-axis of rectifier tank is provided with prejudicially, so the press water by rectifier tank has the speed composition that circles round around nozzle-axis and injected come out, produced the problem of this centrifugal forces enhance diffusion due to circling round thus.And because current integral body is circled round, the water yield of circling round is more, and centrifugal action in the result of the jet water course that sprays is: become whole skimble-scamble current, the practical Weft insertion nozzle of can not saying so.
Summary of the invention
The present invention proposes in view of above-mentioned actual conditions, and its purpose is: a kind of diffusion that can as far as possible prevent to be used for the jet water course of conveyance weft yarn is provided, and improves the Weft insertion nozzle of the productive water-jet loom of weaving cotton cloth.
In order to overcome aforementioned problems, a kind of Weft insertion nozzle of water-jet loom is used in technical scheme 1 described invention, be provided with: the pin that has formed thread guide eyelet, be formed for inserting the hollow bulb of pin and have with outer peripheral face between the nozzle body of giving the water hole that is communicated with, outer peripheral face by aforementioned pin forms with the inner peripheral surface of nozzle body and supplies with the annular chamber of picking with press water with aforementioned the connection to the water hole, the spray-hole that communicates with it, and between aforementioned annular chamber and spray-hole, dispose in the Weft insertion nozzle of water-jet loom of rectifying ribs, it is characterized in that: aforementioned rectifying ribs is to have on the circumferencial direction of the inner peripheral surface of nozzle body at interval, and be set side by side with a plurality of in the upwardly extending mode of outer peripheral face and nozzle-axis side of aforementioned pin, extend on the direction identical with the bus of the inner peripheral surface of nozzle body the bottom of the rectifier tank that the inner peripheral surface of nozzle body and the rectifying ribs of adjacency delimited, and extend the side of rectifying ribs, so that at least a portion relative radius direction of the center line of rectifying ribs has certain angle, so the diffusion of the jet water course after can suppressing to spray.
Weft insertion nozzle is by the general cylindrical shape shape and connected the pin that is used to make the thread guide eyelet two ends that weft yarn passes through and the nozzle body that is similarly the general cylindrical shape shape and has the hollow bulb that is used to insert pin etc. constitutes, be contained at pin under the state of hollow bulb of nozzle body, forming section between the inner peripheral surface of the outer peripheral face of pin and nozzle body is the annular chamber of ring-type.In addition, from be located at outside pump supply with the picking that comes with press water by behind the water-conveying channel, via giving the water hole and arrive annular chamber between outer peripheral face that has been communicated with nozzle body and the inner peripheral surface, thereafter jet water course sprays from the peristome of spray-hole to warp thread, disposes the rectifying ribs that flows that is used to adjust press water between annular chamber and spray-hole.
Because rectifying ribs is to have on the circumferencial direction of the inner peripheral surface of nozzle body at interval, and be set side by side with a plurality of in the upwardly extending mode of outer peripheral face and nozzle-axis side of aforementioned pin, utilize rectifying ribs to absorb the speed composition of the circumferencial direction of relative nozzle-axis so passed through the press water of annular chamber, improved the rectilinear propagation of the jet water course after spraying.In addition, the rectifier tank that passes through the path of the press water of being delimited by the inner peripheral surface of the rectifying ribs side of adjacency and nozzle body is fan-shaped, and the position that is equivalent to this arc is called the bottom.In the present invention, extend on the direction identical with the bus of the inner peripheral surface of nozzle body this rectifier tank bottom, and the mode that has certain angle with at least a portion relative radius direction of the center line of rectifying ribs is extended the side of rectifying ribs, the irrealizable action of prior art can be affacted thus on the press water in the Weft insertion nozzle.
Though the look-ahead technique of aforementioned Patent Document 1～4 has been put down in writing the countermeasure that the uniformity of the jet water course that makes injection improves, but in this case, produce following problem: when converging by the press water behind the rectifying ribs, movement disorder, the whole circumferencial direction of nozzle-axis relatively of current all is the current that circle round, and increases the weight of owing to centrifugal force makes diffusion.In the present invention, though flowing through near the bottom of rectifier tank press water flows on the generatrix direction of nozzle body inner peripheral surface and does not have and follow the aforementioned speed composition that circles round, but the press water of inboard that flows through more close axis is because the mode that has certain angle with the radial direction of the relative nozzle-axis of center line of the thickness direction of rectifying ribs is extended the side of rectifying ribs, follow the speed composition that circles round so have, circle round by this and to relax collision with the outer peripheral face of pin, and after the injection by the bottom near and do not have the current of following the speed composition that circles round and will follow the inboard current that circle round to wrap in the inside and converge, become whole unified jet water course thus.
Be traveling at press water under the situation in the interval from the annular chamber to the spray-hole,, and be necessary to be classified to dwindle the sectional area that passes through the path of press water for the flow velocity of after injection, guaranteeing to stipulate.In the present invention, because additionally on by the press water of rectifier tank follow the aforementioned speed composition that circles round, worry is when dwindling sectional area sharp, current can be disorderly, as countermeasure, can wish that the bottom of rectifier tank is located on the inner peripheral surface (interior to guide surface) as described in the invention of technical scheme 2, this inner peripheral surface reduces on radial direction gradually along with advancing in spray-hole one side.Specifically, constitute the bottom of rectifier tank with taper seat, in the consistent mode that also reduces sectional area gradually the tapering approaching with nozzle-axis is set with advancing of press water, can be from the press water of the bottom surface side transmission of circular cone along with sectional area dwindle gradually near the top side of circular cone, thus can gather way smoothly.
Only give the speed of on the nozzle-axis direction, directly advancing composition for the press water that flows through the rectifier tank bottom, on the other hand, then be attached to the speed composition that advances on the circumferencial direction of nozzle-axis in the inside, can realize the injection of the current that uniformity is good thus, but the combined method of these two kinds of current is because the specification of loom or the shape of pin and nozzle body etc. are various former thereby different, so wish all can change at every turn.So as described in the invention of technical scheme 3, extend the side of rectifying ribs, so that the side beyond distance nozzle-axis predetermined radius, the center line of aforementioned rectifying ribs extends on radial direction, and in the radius of aforementioned regulation, the aforementioned relatively radial direction of the center line of aforementioned rectifying ribs has certain angle, more critically controls the action of the press water in the Weft insertion nozzle, can spray whole unified jet water course thus.
The relative radius direction has under the situation of certain angle in the whole side of rectifying ribs, the speed composition of the circumferencial direction of nozzle-axis becomes excessive relatively, might make the jet water course after the injection be easy to diffusion, in order to limit this situation, a side in (outside) beyond distance nozzle-axis predetermined radius, the center line of rectifying ribs is on the basis of the mode same as the prior art of extending on the radial direction, in more close nozzle-axis one side (inboard), same with scheme 1, the mode that has angle with the center line relative radius direction of the thickness direction of rectifying ribs is extended the side of rectifying ribs, thereby can limit the ratio of the press water of the speed composition that contains circumferencial direction, keep the uniformity of the jet water course after the injection.
Though by effectively utilizing technical scheme 3 and technical scheme 4 described inventions, can spray whole unified current, except independent operation technique scheme 3 or technical scheme 4 described structures, also can adopt both sides' structure simultaneously from spray-hole.
Technical scheme 5 described inventions are used to make the jet water course after the injection stable, it is characterized in that: the rectifying ribs ring-type stream that formation links to each other with annular chamber and spray-hole between the outer peripheral face of its top end face and pin is provided with interval with the outer peripheral face of pin.Though rectifying ribs extends towards nozzle-axis from the inner peripheral surface of nozzle body, but do not contact with the outer peripheral face of nozzle, between the outer peripheral face of pin and rectifying ribs, constitute the freely through without restriction ring-type stream of press water, make the discrete equalization of the flow condition etc. of the press water that flows through each rectifier tank thus, improve the stability of the jet water course after spraying.
According to technical scheme 1 described invention, when picking is passed through rectifier tank with press water, the speed composition that on the press water of the bottom of flowing through rectifier tank, adds the nozzle-axis direction, this is external by adding the speed composition of the circumferencial direction of nozzle-axis near the press water the top end face of rectifying ribs, speed by this circumferencial direction becomes to assign to relax the bump with the pin outer peripheral face, and then by being wrapped in the inside by the press water of the speed composition that does not contain circumferencial direction outside being flow through, and as spreading few unified jet water course to outer jet, even so under the situation of the opening amount of cutting down warp thread, press water can directly not got on the warp thread yet, has improved the productivity of weaving cotton cloth.
According to technical scheme 2 described inventions, can make the rate smoothing ground increase of press water to guide surface by the interior of week in week in the nozzle body or the rectification part, so can suppress to become the generation of turbulent flow composition of the diffusion reason of the jet water course after the injection.
According to the invention of technical scheme 3,4, because can adjust the speed composition that advances at circumferencial direction by near the press water the top end face of rectifying ribs freely, so can provide for the difference of condition of weaving cotton cloth etc. and optimized Weft insertion nozzle.
According to the invention of technical scheme 5, eliminate the differential of the flow velocity of press water of each rectifier tank or pressure by being provided with the ring-type stream, can improve the stability of the jet water course after the injection.

The specific embodiment
Below with reference to the accompanying drawings, describe for preferred implementation of the present invention.
Figure 1A is the sectional side view of shape of the Weft insertion nozzle 1 of expression water-jet loom of the present invention, and the thread guide eyelet 11 of pin 2 connects on nozzle-axis 8 directions, and outer radius portion attenuates on the guide direction steppedly, is formed into the thin head shapes of leading section thus.Nozzle body 3 has that the internal diameter that makes spray-hole 20 right sides narrows down steppedly and the hollow bulb that forms, and contains the rectification part 4 of the rectifying ribs 9 of having packed in stair-stepping bottom one.
Nozzle holder 5 with water-conveying channel that press water flow through 16 of supplying with from the pump of outside is fixed on the periphery of nozzle body 3 by the spray cap 17 that is screwed into nozzle body 3.Press water from water-conveying channel 16 passes through to after the water hole 12 from endless groove 6, the annular chamber 15 in the space between the outer peripheral face 27 of inflow pin 2 and the inner peripheral surface 28 of nozzle body 3, endless groove 6 spreads all in the peripheral part of nozzle body 3 and water-conveying channel 16 corresponding positions and is provided with allly entirely, equally spaced is provided with and connects the inside and outside for water hole 12 on the circumferencial direction of the outer peripheral face of nozzle body 3.Although be transmitted to the press water turbulization in the annular chamber 15, by after being used to adjust rectification part 4 inside of turbulent flow, outwards spray as jet water course from spray-hole 20, draw the weft yarn 7 of the top ends that is positioned at pin 2, picking in the opening of warp thread.
Figure 1B is the A-A profile of Figure 1A, and rectifying ribs 9, when extending on the radial direction shown in this figure 19, is also extending on nozzle-axis 8 directions that connect paper to the inboard to guide surface 14 equal intervals and be radially configuration apart from rectification part 4 interior.The rectifier tank 13 that becomes the stream of press water delimited with the bottom 25 (interior to guide surface 14) of rectifier tank 13 by the side 22 of the rectifying ribs 9 of adjacency, and nozzle-axis 8 one sides are then opened to ring-type stream 24.In addition, the center line 21 and the side 22 of the leading section 23 of rectifying ribs 9 similarly have the angle of cut, so that relative radius direction 19 has angle.
Fig. 2 is from the perspective view of the leading section 23 being seen rectifying ribs 9 of the present invention of press water inflow, though actual rectification part 4 is a ring-type, cuts out a part for explanation and is described.Extend on bus 18 directions of guide surface 14 interior the bottom 25 of rectifier tank 13, and the center line 21 of the leading section 23 of rectifying ribs 9 is not relative radius direction 19 unanimities, but has the angle of cut.In addition, the double dot dash line among the figure is that relative radius direction 19 does not have the rectifying ribs under the prior art mode of the angle of cut.Rectifying ribs 9 extends from the downstream direction of leading section 23 to press water, though finally its top end face 26 is with interior integrated and disappear to guide surface 14, but in this whole interval, the center line 21 and the side 22 of the thickness direction of rectifying ribs 9 similarly have the angle of cut, so that its relative radius direction 19 has the angle of cut.
Under the situation of constituting of rectifying ribs 9 mode shown in Figure 2, the action of press water is shown in Fig. 3 A, Fig. 3 B.Entering the press water of rectifier tank 13, shown in the sectional view of Fig. 3 A, set near the current B near current A and the top end face 26 that flows to rectifying ribs 9 the bottom 25 flow to rectifier tank 13 from annular chamber 15.Current A is because move on same direction with interior bus 18 to guide surface 14, so have the speed composition of nozzle-axis 8 directions, relative with it, current B is owing to the effect of the side 22 of rectifying ribs 9 contains the speed composition that advances on the circumferencial direction of nozzle-axis 8.
Fig. 3 B is the B-B profile of Fig. 3 A, because represented the speed composition of current B, so enter the pressure inside water of rectifier tank 13 has added the circumferencial direction of nozzle-axis 8 at place β owing to the effect of the side 22 of rectifying ribs 9 speed composition V θ from α place shown in Figure 3.This speed composition V θ act as: though from nozzle-axis 8 away from direction impinge upon under the situation of periphery of pin 2 because incident angle becomes big, so can alleviate reaction force.In addition, has the speed composition that inside part only circles round by rectification part and the current that converge.The water yield of circling round of the jet water course that produces from the spray-hole 20 such press waters of injection is few, even at inside part, centrifugal action is on the current that circle round, and its influence is also smaller.That is, relative current B is because current A converges in the mode of surrounding from the outside, so the jet water course that sprays from nozzle bore 20 becomes from integral body the current and injected of looking unified.
The structure of the rectifier tank 13 of gained of the present invention also has multiple mode except mode shown in Figure 2, Fig. 4 represents a wherein example.In this case, the scope that the center line 21 relative radius directions 19 of the thickness direction of rectifying ribs 9 are had an angle of cut is limited to from nozzle-axis 8 to specific radius with interior interval L, and is consistent with the prior art mode in its outside.Because the center line 21 of scope that should interval L has the aforesaid angle of cut, so the side 22 of rectifying ribs 9 has the angle of cut similarly, the dotted line among the figure (drawing on the side 22 of rectifying ribs 9) is represented this boundary line.
At radial direction 19, interval L does not do qualification with the ratio of in addition length of an interval degree, interval L can be arranged near the short interval of the qualification top end face 26 or continue up near the bottom 25 of rectifier tank 13 multiple situations such as long interval.In addition, the double dot dash line among the figure represents that relative radius direction 19 does not have the rectifying ribs of the prior art mode of the angle of cut.In addition, in illustrative example, have in the interval of angle,, also can be a plurality of different angles though make angle identical in the center line 21 relative radius directions 19 of rectifying ribs 9.For example, also can form along with near axis direction and relative radius direction 19 increases the rectifying ribs 9 of angle steppedly.
Fig. 5 has represented the another way example of Fig. 2, the scope that the center line 21 of the thickness direction of rectifying ribs 9 has an angle of cut with relative radius direction 19 is limited in nozzle-axis 8 directions interval K that begins from the leading section of rectifying ribs 9, and a side far away than interval K is consistent with the prior art mode.In addition, the dotted line of drawing on the side 22 of rectifying ribs 9 is represented the boundary line of the scope of the aforementioned angle of cut and scope in addition.In addition, identical with the situation of Fig. 4, the ratio of interval K and length of an interval degree is not in addition done qualification.In addition, the double dot dash line among the figure represents that relative radius direction 19 does not have the rectifying ribs of the prior art mode of the angle of cut.
The another way example of Fig. 6 presentation graphs 2 is the structures that make side 22 relative radius directions, 19 bendings of rectifying ribs 9, its result, and the center line 21 of the thickness direction of rectifying ribs 9 is crooked similarly, and relative radius direction 19 has angle.This mode is characterised in that: with the angle of cut of radial direction 19 along with increasing towards the center, the radius of curvature when crooked or the kind of curve limit.In addition, the double dot dash line among the figure represents that relative radius direction 19 does not have the rectifying ribs of the prior art mode of the angle of cut.
Though the thickness of the rectifying ribs 9 of each figure shown in so far is roughly certain, not necessarily is confined to this, also can be along with the diminishing mode shown in Figure 7 of thickness near the top end face 26 of rectifying ribs 9.In this case, become this mode: the two sides 22 relative radius directions 19 of the rectifying ribs 9 of a slice are extended with different angles, and the center line 21 relative radius directions 19 of the thickness direction of rectifying ribs 9 have angle.
Embodiments of the present invention except shown in these, also have the rectifying ribs 9 shown in the sectional view of rectification part 4 peripheries of Fig. 8 A from leading section 23 to spray-hole 20 continuous situations.In addition, also can implement the structure shown in Fig. 8 B: the bottom 25 of the rectifier tank 13 in week constitutes abreast with nozzle-axis 8 in the rectification part 4, the downstream of rectification part 4 and aperture 10 adjacency make the inner peripheral surface in aperture 10 have certain inclination, are pressed into press water thus.
In the present invention, shape from Weft insertion nozzle 1, do not limit for the quantity in water hole 12 or shape or size, the quantity of rectifier tank 13 or each autoregressive parameter of interval or section shape etc. of rectifying ribs 9, in addition, the section shape of having guaranteed a plurality of rectifier tank 13 also need not be all identical, rectification part 4 that also can be shown in Fig. 8 C is such, alternately disposes two kinds of variform rectifying ribs 9.
