Description

The throttle valve that is used for loom

Technical field

The present invention relates to a kind of valve, especially throttle valve, and move this valve method, make this valve and the braiding (for example picking braiding) field use the method for this valve.The method that the invention still further relates to the loom that comprises this valve and use this valve to weave.

Background technique

In the picking system for weaving, pressurized air is used for pulling out and spinning and they are blown into the race of picking loom from supplying with bobbin.One group of relay nozzle is used to support to spin stride across moving of race, and its width can be several meters.Additional nozzle at the race far-end can make the line of insertion extend in knit operation.US4 has described the example of picking loom in 534,387.

The kind that spins that known basis will weave is regulated the air-flow that flows to main or relay nozzle.For example, smooth firm filament yarn can weave with high gas flow at the relay nozzle place, and unsubstantial spun yarn or spun yarn with some irreqularitys are used than low-flow at the relay nozzle place only and woven.Spin in order successfully to insert two or more, the air-flow of relay nozzle can be set the desired value of the most weak type that spins for, so that spinning can not blown is disconnected, fracture or damage.

The U.S. 4,534,387 provide two airflow rates that are used for relay nozzle, and it is disconnected to select correct air-flow to make that yarn can not blown, and make yarn to insert to stride across the far-end of race with timely arrival opposite side or race.The speed of seam loop is suitable for cooperating the slowest yarn.This machine requires to divide other voltage drop value to the airflow rate of each requirement.

US6,062,273 has described the electricity driving throttle valve that is used to insert nozzle.This throttle valve is included in movably plunger of the interior property direction along the line of boring.Plunger is positioned at apart from the desired distance of valve seat.The valve operation of the type is relatively slow.Under the situation that need change to each insertion airflow rate, valve must move be less than 35 milliseconds during.Second problem of the type valve is that it has around the rubber seal ring of plunger and escapes from valve to prevent pressurized air.The sealing ring be easy to wear and tear and therefore the valve of the type need change each insertion at air-flow under the situation of airflow rate and have the limited life-span.

Because these valves cost an arm and a leg and be that consumption accounts for the object of volume/area, just require to reduce the quantity of valve.Also require to provide and have long lifetime and valve of quick-wearing so not.In addition, also require to have the valve of quick operation.

Fig. 2 illustrates in greater detail according to first embodiment of throttle valve 13a of the present invention and shutoff valve 12a.Throttle valve 13a comprises housing 50, and housing 20 is connected with gas holder 5 in airtight mode.Housing 50 comprises fluid input 54 and the fluid output 55 that is used to accept pressurized air stream.Provide airtight by bolt 52 and seal ring 57.Housing 50 has passage 51, for example boring, and tubular conduit 60 is installed in wherein.In this embodiment, conduit 60 comprises that along its whole length be columniform thin walled tube, although also can be other shape.In preferred embodiment, pipe is made of metal, the about 0.2mm of wall thickness or more specifically wall thickness less than 1mm.Driving component, more particularly motor 70 is installed between the passage 51 of gas holder 5 and housing 50.Live axle 72 extends and is connected to by coupling arrangement 74 upstream extremity of conduit 60 from motor 70.Live axle 72 aligns with the longitudinal axis 61 of conduit 60.Conduit 60 is supported on upstream extremity by live axle 72 and coupling arrangement 74, and is supported on downstream by sleeve pipe or the bearing 58 that is contained between conduit 60 and the housing 50.Bearing 58 forms fixing (for example gluing together) tubular element in the passage 51 of housing 50.Housing 50 has fluid output 55 near the upper surface of housing 50, for example circular bore or slit-like opening.Fluid output 55 comprises the opening on the bearing 58 of the prolongation that is positioned at housing 50 inner openings 55.Gas holder 5 can be connected to air supply pipe (not shown) in a known way.Housing 50 can be installed on the framework 53 near the position the associated nozzles of contiguous loom.

Conduit 60 has one group of inlet opening 62 at its upstream end.Each hole 62 extends to the hollow inside of conduit 60 from the outer surface of the wall of conduit 60.In this embodiment, hole 62 is positioned at around the whole circumference of conduit, along a ring band of 50% that almost is the total length of conduit 60.The quantity of selecting hole 62 is to allow to enter in use the good air stream of flow-catheter 60 inside, and the abundant intensity that keeps conduit 60 simultaneously is to bear the fast moving of air pressure and conduit 60.In the downstream of conduit 60, in conduit 60, be limited with V-arrangement slit 65.Slit 65 extends through arrival hollow inside from the outer surface of the wall of conduit 60.Slit 65 local circumferences around conduit 60 extend.Obviously, the circumferential length of slit 65 is restricted to the part of the circumference of conduit 60, otherwise will cut conduit 60 open.V-arrangement slit 65 aligns with the outlet 55 of housing 50.Outlet 55 size is made it is only overlapped with the part of slit 65.As noted above, conduit 60 can be around longitudinal axis 61 rotations.During use, motor 70 rotates live axle 72, and therefore conduit 60 is turned to specific angular orientation.Slit 65 defines the local or part of which of slit 65 with respect to outlet 55 position and aligns with outlet 55 and therefore regulate how many air and can flow by conduit 60 with by outlet 55 from gas holder 5.Like this it can almost do not have between air-flow and the maximum airflow (for example form pass from conduit 60 to the opening of outlet 55 0% or 100% the flowing of opening of opening 55) regulate air-flow by outlet 55.Certainly, according to a kind of modification, pass opening flow also can for example export 55 opening 20% to 100% between.For example provide different flow rates by the shape of conduit 60 or size being made at the different segment place around the circumference of conduit 60 around the shape of the slit 65 of the circumference of conduit 60.

Shutoff valve 12a (schematically illustrated) is installed in the downstream of throttle valve 13a.Plunger 83 and valve member 82 act on the valve seat and be biased into closed position (as shown in the figure) by spring 84 when normalities.Valve member 82 can (for example be used electromagnetic mode) and move, and overcomes the bias voltage of spring 84 and enters into open position and flow to outlet 88 from exporting 55 to allow air.Outlet 88 is connected to main nozzle or is connected to relay nozzle, as shown in Figure 1.

Fig. 3-5 shows second embodiment of throttle valve 13b and shutoff valve 12b.Main difference is the design of the entrance and exit of conduit 60.In this embodiment, inlet comprises a series of slit 62A.As illustrating more fully among Fig. 3, the adjacent ring of slit 62A is offset each other.For example, in this embodiment, housing 50 does not comprise bearing components separately, and the downstream of conduit 60 is entered housing 50 by direct guiding.

The outlet 65A of conduit 60 comprises one group of hole, forms around a ring band of the circumference part of conduit 60.This group hole 65A is arranged to and can realizes that at the different segment place around the circumference of conduit 60 flow rate increase gradually, therefore can or by making conduit 60 realize different flow rates flowing from the end to end of outlet 65A through the valve opening with respect to the outlet 55 of housing 50.Figure 4 and 5 illustrate in greater detail one group of hole 65A separately.Should be appreciated that the pattern with the Fig. 5 shown in the planimetric map is enclosed in around the outer wall of conduit 60.At first end of the outlet 65A of conduit 60, the hole has little diameter.In this example, little grouping 91 has minor diameter (for example 0.25mm).Along with the diameter increase in each hole and the quantity increase in hole are moved towards second section that exports in the hole.The hole of the second little grouping has than major diameter (for example, 0.5mm).Align with linear fashion in the hole of the little grouping 92A of this diameter, the hole of second of this diameter little grouping 92B is staggered around center line simultaneously.Should staggeredly compare with aligned has increased attainable flowing, and keeps the intensity of conduit 60 simultaneously.The hole that the hole of the 3rd little grouping 93 has than major diameter (for example 1.1mm) and last little grouping 94 has maximum diameter (for example 1.5mm).In this last little grouping 94, the hole is arranged to, and along with moving along direction 98 by rotary tube 60 apertures, every row has the hole of accelerating, and is arranged to align with the outlet 55 of housing 50 in use in these holes.The advantage that the improved form of the outlet 65A of conduit 60 has is that it can keep being better than the intensity of the conduit 60 of slit 65, and can be around the major part setting of total circumference of conduit 60.In addition, can accurately make the outlet 65 of conduit 60, the slit 65 that more particularly exports comparable Fig. 2 in hole of 65A is made more accurately.

In Fig. 5, the possible position of the outlet 55 of housing 50 with respect to the outlet 65A of conduit 60 is shown also.Shown in solid line, the flow that the outlet 55 of housing 50 is arranged to conduit by housing 50 and outlet 55 with respect to the hole of the outlet 65A of conduit 60 is by 100% of the flow of free export 55, simultaneously with the position shown in the dotted line, it only is sub-fraction by the flow of free export 55 that flow by the conduit 60 of housing 50 and outlet 55 is arranged in the outlet 55 of housing 50.

Although Fig. 2 and 3 shows different inlets and different outlets, any in these remodeling can independently do not used with other relatively, for example can be the embodiment's of Fig. 2 and 3 combination.

Fig. 6 shows another embodiment of the present invention.In Fig. 6, conduit 160 is conical, has wide mouth 161 and has narrower cylindrical cross-section 162 in downstream at upstream extremity.Downstream 162 and outlet 65A move in the same manner as described above.This alternative form of inlet have air-flow towards the cross section 162 funnelling.Mouth 161 be provided with the easy path that is used for air-flow inflow catheter 160 inside and therefore on the wall of conduit 160 without any need for the hole or slit (62,62A).As in other embodiments, conduit 160 can be around its longitudinal axis 61 rotations.Motor 70 has the live axle 72 that aligns with longitudinal axis 61.The one group of arm that forms coupling arrangement 73 is connected to conduit 160 with live axle 72.Can have two, preferably be three or more arms 73.Air can organize that free-flow enters conduit 160 inside between the arm at this.As seen to compare manufacturing more complicated for this embodiment and the cylindrical tube 60 shown in the previous embodiment.

As mentioned above, whole motor 70, live axle 72,

coupling arrangement

73,74 and conduit 60,160 are installed in the air flow path between the outlet 55 of gas holder 5 and housing 50.This advantage that has be the air by valve can flow these parts of cooling and prevent overheated.Also mean between the valve member that moves, more particularly do not need sealing between conduit 60,160 and the outside air.

According to a replacement scheme (not shown), air-flow also can flow through motor itself rather than center on motor 70 shown in Fig. 2,3 and 6.For this reason, the live axle 72 of motor 70 can or keep passage to pass through along motor 70 to allow flowing of air by the quill shaft support.

Being necessary provides power supply and control signal by actuating cable 40 and connector 41 to motor 70.This actuating cable 40 can be installed by the boring on the wall of shell 50.Boring should seal (such as by airtight) to prevent the air escape.Because actuating cable 40 be arranged to fixed, so that sealing requires is simple.This actuating cable 40 can be installed by the boring (not shown) on the wall of gas holder 5 according to alternate embodiment.

Can make the friction minimum between the part of outlet 65 regional conduits 60 and housing by the copper or polymeric material supporting ring 58 that conduit 60 rotates therein.Supporting ring 58 comprises the interior opening 59 of extension part of the opening 55 that mainly is arranged on housing 50.Even rub, because this fricative heat also can be absorbed by the air-flow through throttle valve 13a, 13b.Do not increase although do not wish

throttle valve

13a, 13b excessive temperature, have found that warm air is inserted with favourable influence to auxiliary parallel.Might can between supporting ring 58 and conduit 60, flow by air-flow.This air-flow can not be disadvantageous, because this air-flow is with respect to less through the air-flow of the opening 65 of conduit 60 and can in time not change or only can slowly change.

The position of the conduit 60 of

throttle valve

13a, 13b is determined by motor 70.Motor 70 can be a stepping motor, and it has the step number of suitable quantity can realize the airflow rate control of the degree that required.Perhaps motor 70 also can be servomotor, for example DC servomotor.Can be from being attached to conduit or being attached to the encoder of the live axle 72 of motor 70, the feedback that for example optical encoder (not shown) provides the angular orientation of conduit 60.Also might use at valve outlet port 88 or at the pneumatic sensor of the outlet 55 of housing 50 and produce the feedback signal that is used for air-flow.Also might use at valve outlet port 88 or at the pressure transducer of the outlet 55 of housing 50.

One embodiment is with the stepping motors operation that had altogether for 80 steps, and 20 steps were used for high velocity air and 60 steps were used for low speed flow.Controller 20 usefulness on the one hand live axle 72 the position, angle or insert circuit regularly and therefore conduit 60,160 the position, angle and on the other hand the relation between its flow rate of realizing programme.The position of coming operated

throttle valve

13a, 13b according to the master controller 20 that is used for air jet picking loom is to set air-flow for desired speed at required time.The control functional element 22 that is used for motor 70 (for example different motor 70 of

throttle valve

13a, 13b) can form a part of total body controller 20 of this machine.Control functional element 22 can receive the input of the desired airflow rate of indication, for example from the input of the instruction group 21 that is used for current Fabric Design, and output cause that at

specific throttle valve

13a, 13b place at least one motor 70 moves into the control signal of an inflection point, described inflection point can make this valve realize desired flow rate.Control functional element 22 alternately with each motor 70 local logotype.In this case, the control signal that is applied to each electric motor controller can be indicated desired flow rate.Certainly, also can come according to the signal of parallel prober 6 motor 70 is controlled, in other words, as function in the arrival of the corresponding parallel 8a in parallel prober place, 8b, 8c.

Consider an exemplary knit operation, use three kinds of

different yarn

8a, 8b and 8c (also being called A, B and C), each requires different airflow rates.Use the yarn insertion sequence of ABCABC, throttle valve can normally be operated each insertion.The braiding speed of inserting for per minute 1200 times must per second operation throttle valve 20 times, promptly per 50 milliseconds once.As everyone knows, in each braiding circulation, inserting the time lag is at interval half of a braiding circulation available time basically, that is, each time lag of inserting and being used to is lifted the time lag that the parallel of insertion prevents the line of fall.If people are chosen between twice insertion for example mobile conduit 60 during the time lag of lifting, just having an appointment 20 milliseconds is used for throttle valve ready being used for inserted next time.Even people select to use in fact whole insertion to circulate mobile conduit 60, also only have 50 milliseconds and can be used to mobile conduit 60.Certainly, also can use other yarn insertion sequence according to the pattern that will weave.Yarn for AABBCC inserts in proper order, only need change throttle valve after per twice insertion, inserts in twice continuous weaving machine cycles because have the identical yarn of character much at one.

Again referring to Fig. 1,

throttle valve

13a, 13b ... 13x can be positioned at gas storage holder or gas holder 5 and one group of

relay nozzle

4a, 4b ... between the 4x or between gas holder 5 and

main nozzle

2a, 2b, 2c, 2d, 2e, the 2f.Shutoff valve 10a to 10f, 12a to 12x, 14 dispensable, but preferred.Fig. 1 shows each from

identical throttle valve

13a, 13b ... a plurality of

relay nozzle

4a, 4b that 13x presents ... 4x.

Different relay nozzle

4a, 4b along loom ... 4x can different airflow rates move.For example, last can be organized relay nozzle 4x and can insert the parallel of end with maintenance with than those more high speed airflow controls that begin to locate at race.Throttle valve according to the present invention can be used for selecting any airflow rate of needs.Any other function along the airflow rate of race is chosen to, and is high gas flows and be than low-flow to some other relay nozzle to some relay nozzle for example.The use of throttle valve allows all relay nozzle, also can use a main gas holder 5 to all main nozzles.In Fig. 1, each throttle valve is given one group of three

relay nozzle

4a, 4b ... 4x supplies air.According to another form, each relay nozzle or have the nozzle sets of two, four or more relay nozzle can be by same throttle valve supply air.

Also can be used for optimizing air-flow by each relay nozzle according to throttle valve of the present invention, this can cause inserting the air-flow that uses still less and high-pressure air still less.Use reduces according to throttle valve air-flow of the present invention can be up to 30%.Other use of throttle valve can be different, for example increases or reduce the air-flow during inserting, so that for example produce than air flow during through relay nozzle when parallel, and the parallel air-flow that generation reduces during further from relay nozzle.As from US3, in 672,406 known to, during inserting, change other possibility of air-flow circularly.

If use throttle valve to provide air-flow, need before opening respective switch valve 11a to 11f, throttle valve be set to desired throttle position to main insertion nozzle.If use throttle valve to the relay nozzle supply air flow, then preferably can before opening corresponding shutoff valve 12a to 12x, throttle valve be set to the throttle position of requirement.Can insert parallel 8a, 8b simultaneously by changing throttle position, 8c obtains more advantages.
