Description
Technical field
The present invention relates to be used for the transfer valve and the press water feeding mechanism of the switch pressure water of water jet loom.
Background technology
Transfer valve for the picking press water that is used in water jet loom generally has following structure.Have the water inlet that is communicated to the press water source of supply and be communicated to a plurality of delivery ports of the terminal delivery port of Weft insertion nozzle at valve body.Simultaneously,, the water guide road that selectively is communicated with a water inlet and a delivery port is set, is used for driving spool inserting on the spool that leads in valve body.Water inlet is communicated to a delivery port by the water guide road.
Adopt such transfer valve as a picking press water feeding mechanism, as the content of in Japanese kokai publication hei 10-1847 communique, putting down in writing.In the prior art, the spool that is configured in the valve body is driven by the electric actuator of for example rotating electromagnetic circle, and supply selectively from a plurality of Weft insertion nozzles one of the press water of press water source of supply by transfer valve.
In existing transfer valve, the water guide road that is arranged on the spool just forms Y-shaped, so when press water flowed into the water guide road of spool and passes through this water guide road, press water will collide the wall on water guide road, thus rotary spool.Therefore, the electric actuator is to make spool to opposite spin, thereby makes it return to original state.
Consequently, make spool alternately to a direction and the rotation of another direction, thereby between spool and valve body, produce wearing and tearing, so not only can produce the leakage of press water, and can between water inlet and water guide road and water guide road and delivery port, produce the skew of moment, owing to these reasons make the injection of the press water that ejects from Weft insertion nozzle die down.
Summary of the invention
The objective of the invention is to be to provide a kind of when press water flows into the water guide road of spool, transfer valve and press water feeding mechanism that spool can not be rotated.
For a kind of transfer valve provided by the invention, include respectively: have the water inlet that is communicated to the press water source of supply respectively, and the valve body that is communicated to a plurality of delivery ports of one of a plurality of terminal delivery ports of containing a Weft insertion nozzle at least; And with the slotting spool that leads in this valve body of rotatable state, this spool has the water guide road that is communicated with described water inlet to this delivery port.
At transfer valve provided by the invention, this water guide road has and comprises the face parallel with the axis of this spool, and separates to the direction of this axis mutually, simultaneously to the report to the leadship after accomplishing a task groove of two faces of direction extension of this axis.Regulation position of rotation at this spool can be communicated with described water inlet and specific delivery port in addition, and the position of rotation at this different spools can be communicated with described water inlet and another delivery port different with this specific delivery port simultaneously.Above-mentioned parallel face is at the position of rotation of a regulation of this spool, and from this water inlet and straight line approximate vertical by this spool pivot, and any one delivery port all opening on described groove.
In above-mentioned transfer valve, flow into the press water on water guide road, though can collide on the face parallel and push this face with valve core axis, but collide on this face with the direction of approximate vertical, thus will cause act on and position that this pivot leaves on produce rotation torque and the distance that pushes in right angle orientation between the pivot of the power of this face and spool diminishes at spool.Therefore the rotation torque that acts on spool diminishes and can rotary spool.
And, in above-mentioned transfer valve, press water be by face parallel in spool pushing spool to valve body, positive keep the position of rotation (rotary angle position) that spool is being stipulated.Therefore, can not take place, be communicated with, and can suppress the reduction press water injection of Weft insertion nozzle so be unlikely to hinder because the swing of spool produces the skew of water guide road and delivery port.
Above-mentioned groove is to extend to the direction that connects this water inlet and delivery port, simultaneously also can be open at the outer peripheral face of spool.By such design, press water is to collide behind this parallel face so, can arrive valve body along this parallel face, the water inlet side can be crooked so the press water after colliding can not collide on other wall, thereby can not produce the pressure loss owing to crooked, revolving force can not acted on the spool yet.
For another kind of transfer valve provided by the invention, the regulation position of rotation that above-mentioned water guide road is included in described spool is communicated to this water inlet, and to first water route that the pivot of this spool extends, and when being communicated to described any one delivery port with less than with from the angle of this water inlet by these pivot straight line 70 degree to this crisscross extension in first water route towards above-mentioned pivot so that be communicated to second water route in this first water route.Above-mentioned spool is at the position of rotation of the defined position facing to this water inlet in the inwall in this second water route, have with this straight line with 90 ° ± 20 ° walls that intersect.
For second above-mentioned transfer valve, can collide at this wall in second water route and push this wall though flow into the press water on water guide road, show the right angle greatly and collide at this wall, so spool is acted on revolving force hardly.
In addition, collide press water at above-mentioned wall, be by wall pushing spool to valve body, positive keep the position of rotation that spool is being stipulated.Therefore can not produce because the swing of spool makes the skew between water guide road and delivery port, can not hinder connection, so can suppress the injection that Weft insertion nozzle reduces press water.
For the third transfer valve of the present invention, above-mentioned water guide road includes the regulation position of rotation at described spool, be communicated to described water inlet and to first water route that the pivot of this spool extends, and be communicated to any one delivery port and to this crisscross extension in first water route, towards this pivot so that be communicated to second water route in this first water route.Above-mentioned spool facing to the position of described water inlet, has the hole to this water inlet opening at the position of rotation of this regulation in the inwall in this second water route.
In above-mentioned the third transfer valve, flow into the press water in first water route from water inlet, be end wall (end diapire in hole just) the outward direction rebound that collides in the hole, and from the perisporium of multi-direction collision in the hole.Therefore, press water acts on the direction of the power (pushing force) on the spool when pushing spool by hole wall, to multi-direction dispersion.And therefore, the revolving force that acts on spool is roughly balanced at left and right directions, thereby prevents the rotation of spool.
In addition, press water to valve body, positive is kept the position of rotation that spool is being stipulated by hole wall pushing spool.Therefore can not produce because the water guide road that the swing of spool causes and the skew of delivery port, thereby can not hinder connection, reduce the press water injection so can suppress Weft insertion nozzle.
Above-mentioned hole can comprise the state of the axis in this first water route, to extending in the opposite direction with the side of this water inlet.Form such structure, flow into the press water on water guide road so from water inlet, though collide at the end wall in hole and push the end wall in hole, because first axle is contained in the hole, so it is balanced more at left and right directions to act on the revolving force of spool, prevents the rotation of spool effectively.
For the 4th kind of transfer valve of the present invention, above-mentioned water guide road is at the regulation position of rotation of described spool, can be communicated with described water inlet and specific delivery port, and can be communicated with this water inlet and other delivery port at the different position of rotation of this spool, at at least one regulation position of rotation of this spool, a part of exposing in described water guide road on the valve body inwall forms facing to described water inlet then.
In the 4th kind of above-mentioned transfer valve, the press water that flows into the water guide road is directly come in from water inlet, is facing toward on the inwall of water inlet by the collision of water guide road in inner body wall.Therefore, can not push spool, revolving force does not just act on spool.
For press water feeding mechanism of the present invention, comprise above-mentioned any one first transfer valve, and the special-purpose electric actuator that is used for driving the spool of this transfer valve.Form such structure, even the electric actuator is kept spool when the power of position of rotation is insufficient, spool also can be maintained the position of rotation of regulation by the press water that flows into the water guide road.
Press water feeding mechanism of the present invention further includes: above-mentioned more than one second transfer valve; Be communicated to the first press water source of supply of this first transfer valve; And the more than one second press water source of supply that is communicated to this second transfer valve.Also the spool of this first and second transfer valve can be attached at same axle goes up and is driven by this electric actuator.
Be connected to each other a plurality of transfer valves spool and avoid on a plurality of transfer valves, being provided with respectively the electric actuator, when general spool because of transfer valve on one side rotates, can rotate the spool of the transfer valve of another side, so because the rotation of the spool that press water causes can produce related disadvantage mutually.
Under the situation of press water feeding mechanism of the present invention, when the water guide road of press water by transfer valve, can rotary spool, so can not rotate the spool that is attached at other transfer valve on the spool yet.Thereby do not have because non-selected transfer valve rotates the spool of the transfer valve of the selection that is attached at its spool, and reduce from the situation of the press water injection of selected Weft insertion nozzle, opposite yet can the generation because the situation that selected transfer valve rotates the spool of the non-selected transfer valve that is attached at its spool be not so can produce from non-selected transfer valve bad to outside discharge pressure water.
And, spool is pushed to valve body with press water when adopting, and during the above-mentioned transfer valve of positive restriction spool rotation, on one side spool just maintain the position of rotation of regulation, thereby suppress since press water by being attached at the rotation of the another side spool of spool on one side.
In the present invention, each also can be a Weft insertion nozzle at a plurality of terminal delivery ports.In addition, supply possesses to comprise in the terminal delivery port of each transfer valve of the press water source of supply of each transfer valve the press water from corresponding press water source of supply is discharged to outside water discharge outlet for press water.

The specific embodiment
Referring to figs. 1 through Fig. 3, press water feeding mechanism 10 is the water jet looms that are used to adopt the polychrome picking of first and second Weft insertion nozzle (drawing on the figure).First and second Weft insertion nozzle be corresponding to each can picking weft yarn.
Press water feeding mechanism 10 is to adopt first and second transfer valve 12 and 14, to optionally be supplied to any one device in first and second Weft insertion nozzle from each for example first and second press water source of supply 16 of feed pump and press water of 18 corresponding to transfer valve.
Spool 24 and 26 is made into one, and is attached on the driving shaft 34 as the electric actuator 32 of rotating electromagnetic circle by hookup 36, is synchronized with loom and rotates driving simultaneously with the sequential of regulation.At illustrated embodiment raising middle flask 28 and 30 also is integrally formed.
Each pipe 54,56,58,60,62,64 is by fixedly tool and fixed screw are attached to pairing case 28 or 30.Press water source of supply 16 and 18 drives the water that attracts in the accumulator tank (not drawing on the figure) with the sequential of regulation synchronously with loom respectively, is fed to water inlet 38 and 40 as press water by managing 54 and 56.
In illustrated embodiment, first and second Weft insertion nozzle and first and second water discharge outlet, all terminal delivery port of conduct injection or discharge pressure water.
Selecting stop position, is owing to selected its transfer valve and pairing Weft insertion nozzle, is fed to the position of corresponding Weft insertion nozzle for the press water that is used for being supplied.Relative therewith, non-selection stop position is owing to non-selected its transfer valve and corresponding Weft insertion nozzle, and the press water of being supplied is recovered to the position of accumulator tank from the outlet of correspondence.
For two transfer valves 12,14, transfer valve on one side is to be driven when selecting corresponding Weft insertion nozzle, and supply pressure water is to Weft insertion nozzle, this moment, the transfer valve of another side promptly became nonselection mode with corresponding Weft insertion nozzle, so for example be driven into discharge pressure water to accumulator tank, (not drawing on the figure) drives spool 24 and 26 simultaneously by actuator 32 in this manner.
; spool the 24, the 26th, the driving of one; so when spool 24 moves to selection stop position shown in Fig. 3 (A1); spool 26 just moves to the non-selection stop position shown in Fig. 3 (B1); when spool 26 moved to selection stop position shown in Fig. 3 (B2), spool 24 just moved to non-selection stop position shown in Fig. 3 (A2).
Each water guide road 50 and 52 as shown in Figure 3, include by with corresponding spool 24 and 26 axis (just, pivot) 66 parallel faces (in an embodiment for containing the face of axis 66) 68, and leave the formed flow passage groove of two faces 70,70 that intersect with axis 66 (on the edge graph picture) simultaneously mutually to the direction of axis 66.
Each water guide road 50 and 52 forms in illustrated embodiment to valve core diameter's direction of circular section and extends, corresponding to the flow passage groove shape of U font that is opened in the valve body inner peripheral surface or font.Therefore face 68 is as the bottom surface of flow passage groove, face 70,70 sides as flow passage groove.
Also have, press water feeding mechanism 10, comprise spool 24,26 positions of limiting above-mentioned transfer valve 12,14, simultaneously and spool 24,26 with the stopper 72 of angle rotation, and plate 74,74 (drawing on the side figure) is adjusted in a pair of position that is used for limiting the angle rotating range of stopper 72.Stopper 72 is mounted on the hookup 36. Plate 74,74 is adjusted in the position, is that the mode with the angle rotation possible range that can adjust stopper 72 is installed in case 28.
At least in the running of loom, pressurize into the press water of setting from press water source of supply 16 and 18, be fed to corresponding transfer valve 12,14 respectively. Transfer valve 12 and 14 water inlet 38 and 40 axis 66 are axis 66 centers of rotation just by spool 24 and 26.Therefore, flow into the water of water guide roads 50 or 52 from water inlet 38 or 40, just to the axis 66 of the spool 24 of correspondence or 26 just center of rotation advance.
In press water feeding mechanism 10, when selecting first Weft insertion nozzle, transfer valve 12 is placed on selection mode, and second Weft insertion nozzle and transfer valve 14 then are placed on nonselection mode.
Under this state, be the selection stop position shown in Fig. 3 (A1) for spool 24 displacements of transfer valve 12,26 displacements of the spool of transfer valve 14 are the non-selection stop position shown in Fig. 3 (B1).Therefore, though be fed to first Weft insertion nozzle by transfer valve 12, just be discharged to accumulator tank from water discharge outlet by transfer valve 14 from the press water of press water source of supply 18 from the press water of press water source of supply 16.
For this situation, when second Weft insertion nozzle is placed on selection mode, the spool 26 of transfer valve 14 is switched to the selection stop position shown in Fig. 3 (B2), the spool 24 of transfer valve 12 is the non-selection stop position shown in Fig. 3 (A2) with regard to displacement.Therefore, though can be fed to second Weft insertion nozzle by transfer valve 14, be discharged in the accumulator tank by outlet by transfer valve 12 from the press water of press water source of supply 16 from the press water of press water source of supply 18.
Shown in Fig. 3 (A1), wherein when transfer valve 12 maintains the selection stop position, flow into the press water on water guide road 50 from water inlet, be to pivot just axis 66 advance, colliding the face 68 parallel with axis 66, particularly water collides face 68a (comprising axis 66 at embodiment) thereby goes up and push this face 68a.
Press water is to show the right angle greatly to collide at water collision face 68a, so pushing forms the press water pushing force that water collides the wall of face 68a (=water is collided the power of face 68a right angle orientation), with the pivot of spool 24 just the distance of axis 66 roughly become zero, also can produce left and right sides either party's rotation torque hardly.See embodiment again, comprise pivot axis 66 just because of water collides face 68a, so the distance of pushing force and spool 24 pivots becomes littler, the balanced simultaneously rotation torque at each left and right directions that collides the zone can rotary spool 24.
Flowing into the press water on water guide road 50 in addition, is to collide face 68a pushing spool 24 to valve body 20 by water.Therefore, spool 24 is maintained the position of rotation of regulation, the particularly positive selection stop position that maintains.
When transfer valve 14 maintains chosen position,, produce same effect also as transfer valve 12 same purposes.
Above-mentioned result can prevent because the swing of spool 24 hinders the connection of water guide road 50 and delivery port 42, and therefore restrain from the press water of Weft insertion nozzle and sprayed the situation that reduces.
The flow passage groove of transfer valve 12,14, the direction that all forms the delivery port of corresponding each Weft insertion nozzle when selecting is extended, and arrives the inside of valve body.Thereby, flow into the press water on water guide road 50,52 when selecting, collision is behind the face of collision 68a, can arrive valve body along face 68a, 68c, consequently collide the press water behind face 68a, can not collide other wall and flexing does not produce because the collision of press water or the crooked pressure loss do not have revolving force yet and affact on the spool.
As the water guide road, replace above-mentioned forming flow passage groove at spool, also can on spool, form a plurality of water routes.
With reference to Fig. 4, transfer valve 80 comprises: body 82; And can be with the spool that is configured in valve body 82 84 of angle rotation.Valve body 82 is the same with the transfer valve of having narrated 14 (or 12), has a water inlet 40 (or 38), and two delivery ports 46,58 (or 42,44).Delivery port the 46, the 48th is connected on the different Weft insertion nozzles.
In illustrated embodiment, α forms 30 °, and β is 90 °.Just wall 96 and 98 is respectively at first and second selection stop position of spool, to from the straight line of water inlet 40 by axis 66, with 90 ° of intersections.Water route 94 is to intersect with 30 ° with water route 90,92.
In transfer valve shown in Figure 4, flow into the press water of water route 90 or 92 from water inlet 40, though can collide this wall 96 or 98 of pushing on wall 96 or 98, but collide on wall 96 or 98 with approximate right angle ground, so pivot of pushing wall 96 or 98 press water the pushing force power of wall right angle orientation (=to) and spool 84, just the distance with axis 66 is very little, has revolving force hardly and acts on spool 84.
Collide press water in addition in wall 96 or 98, by wall 96 or 98 pushing spools 84 to valve body 82, the positive position of rotation of spool 84 of keeping in regulation.Therefore, can prevent because the swing obstruction water guide road 86 of spool 84 and being communicated with of delivery port 46,48 can be restrained the press water injection of reduction from Weft insertion nozzle.
In above-mentioned transfer valve 80, can make β form the interior angle of 90 ° ± 20 ° scopes, α is the angle less than 70 °.
That is to say that water route 94 and the water route 90 that is communicated with water inlet 40 or 92 can extend to the angle [alpha] less than 70 °, with the water route 90 that is communicated to water inlet 40 or 92 can be to intersect less than 70 ° angle [alpha].
This outside wall surface 96 and 98 to passing through the pivot straight line of axis 66 just from water inlet 40, can be intersected with water route 90 and 92 respectively with the angle beta in 90 ° ± 20 ° angular ranges respectively.
With reference to Fig. 5, transfer valve 100 is communicated to water inlet 40 when water route 90, when water route 94 is communicated to delivery port 46, has the wall 96 that intersects with angle beta in 90 ° ± 20 ° angular ranges and water route 90, but be not possess wall 98 with above-mentioned transfer valve 80 differences.
, the delivery port 46 of this transfer valve 100 is communicated to Weft insertion nozzle, and delivery port 48 is communicated to water discharge outlet with the different of transfer valve 80, so the effect same with transfer valve 80 produces same effect.And transfer valve 100 also can be communicated to water discharge outlet with delivery port 46, and delivery port 48 is communicated to Weft insertion nozzle.
With reference to Fig. 6 and Fig. 7, the water inlet 40 of transfer valve 102 is 75 ° by the straight line of axis 66 and the angle beta of wall 96 and 98, to the water route 90 that is communicated with water inlet 40 or 92 and the angle [alpha] in water route 94 be 30 °.
Fig. 7 is in above-mentioned transfer valve 102, will push the revolving force to spool that wall produced (rotation torque) on water guide road 86 owing to press water, and this wall 96 and 98 possesses the situation (A) at spool 84, the figure that makes comparisons with the situation that does not possess (B).
Possess the situation that wall 96,98 is arranged, pushing force F is divided into the power A1 perpendicular to wall 98 shown in (A), and along the power B1 of wall 98 directions.Relative therewith, not possessing had wall at 96,98 o'clock, and pushing force F is divided into the power A0 perpendicular to water route 94 internal faces shown in (B), and along the power B0 of internal face direction.
Act on the rotation torque of spool 84 in addition, when the wall 96,98 shown in (A) is arranged when possessing, be perpendicular to the power A1 of wall 98, and power A1 and pivot distance L 1 long-pending of axis 66 just, do not have wall at 96,98 o'clock, for vertical in the water route power A0 of 94 internal faces, and the amassing of the distance L 0 of power A0 and axis 66.
Though A1＞A0, as can be seen from Figure 7 L1＜＜L0, so rotation torque becomes following formula:
A0×L0＞A1×L1
Therefore, owing to form wall 96,98, can lower the revolving force that acts on spool 84 significantly at spool 84.Thereby in transfer valve 102, also similarly act on transfer valve 80, produce same effect.
With reference to Fig. 8, transfer valve 110 comprises: valve body 112, and be configured in valve body 112 may be with the spool 114 of angle rotation.Valve body 112 is the same with the transfer valve of having stated 14 (or 12), has a water inlet 40 (or 38), and two delivery ports 46,48 (or 42,44). Delivery port 46,48 is connected respectively to different Weft insertion nozzles.
When spool 114 the regulation position of rotation the time, water route 120,122 is communicated to water inlet 40.Shown in Fig. 8 (A), when water route 120 was communicated to water inlet 40, water route 124 was communicated to delivery port 46.Shown in Fig. 8 (B), when water route 122 was communicated to water inlet 40, water route 124 was communicated to delivery port 48.
For spool 114, when spool 114 rotates to the state of regulation position of rotation, in 124 inwalls of water route,, has hole 126 and 128 to water inlet 40 openings with respect to the place of water inlet 40.In illustrated embodiment, be hole 126 and 128, by forming with the coaxial cylindric space that is connected on water route 120 and 122.
And at transfer valve 110, flow into the press water of water routes 120 or 122, collide in the hole 126 or 128 end wall (end diapire in hole just), collide in the hole 126 or 128 perisporium from a plurality of directions to a plurality of direction rebounds from water inlet 40.Therefore, when press water passes through the wall pushing spool 114 of hole 126 or 128, to the pushing force directive effect of spool 114, and to a plurality of directions dispersions.Therefore, act on the roughly left and right directions equilibrium of revolving force of spool 114, prevent spool 114 rotations.
Press water by hole wall pushing spool 114 to valve body 112, the positive position of rotation of spool 114 of keeping in regulation.Therefore, water guide road 116 and delivery port 46 or 48 obstructions that are communicated with have been prevented, so can restrain the injection that reduces from the press water of Weft insertion nozzle owing to the swing generation of spool 114.
