In Fig. 1,3,5,6,7,8,9 and 11 of following explanation, the direction that the direction indication compressed air of representing with arrow flows.
(the 1st embodiment: the air feeder that monochromatic loom is used)
See figures.1.and.2, air feeder 10 is used to have the monochromatic loom of 1 main burner 12.
Compressed air supply source 14 comprises: the pressure source resemble the compressor (not shown); The supplementary compressed air adjuster that is connected with the air outlet slit of this pressure source by pipe arrangement 20 (is designated hereinafter simply as " adjuster ".) 22; The compressed air storage tank that is connected with the air outlet slit of adjuster 22 by pipe arrangement 24 (is designated hereinafter simply as " gas tank ".)26。
The pipe arrangement 28 that stretches out from 1 air outlet slit of gas tank 26, is connected with main burner 12 by open and close valve 30, compressed air governor 16, converging roads 32 and open and close valve 34 these orders towards the downstream from gas tank 26.The pipe arrangement 36 that stretches out from other air outlet slit of gas tank 26 is by compressed air governor 18, is connected with converging roads 32 on being configured in the pipe arrangement 38 that stretches out from compressed air governor 16.
Loom with above air feeder 10 is done following such action.
The weft yarn 40 that flies away utilizes the cutter 42 that is configured in main burner 12 and weaves cotton cloth the confession yarn side between (not shown), and the sequential of stipulating with aftermentioned is cut off.
(during the 1st) during picking when loom turns round, mean that the picking of the angular range that should be sprayed by main burner 12 sprays, be from 80 ° to 160 ° picking scope M, to carry out at crankshaft angles θ.The cut-out of weft yarn 40 be crankshaft angles θ be 20 ° and near the cut-out scope in carry out.(during the 2nd) during cutting off when loom turns round, mean that the cut-out of the angular range that should be sprayed by main burner 12 sprays, be to comprise that cut-out scope, crankshaft angles θ carry out from 340 ° to 30 ° cut-out spray regime C.
When picking was sprayed, open and close valve 30 and 34 was opened simultaneously.And when cutting off injection, open and close valve 30 is not opened, and open and close valve 34 is opened.
Cut off to spray is such injection: residual after the weft yarn of giving tension force in the time of will being beaten up by cutter 42 is partly cut off is subjected to the counteractive effect of tension force and do not deviate from from main burner 12 for yarn side weft yarn 40 (weft yarn that stretches out from main burner 12).
In other words, the compressed air of the essential big discharge of flying away of weft yarn 40.Therefore, in picking scope M, open and close valve 30 and 34 is all opened, and utilizes compressed air governor 16 and 18 to adjust flow, and makes the compressed air stack of flowing in pipe arrangement 38 and 44 in converging roads 32.
Thus, a large amount of compressed air is supplied with to open and close valve 34, and by opening open and close valve 34, the compressed air that this is a large amount of supply to main burner 12.Thus, weft yarn 40 utilizes the compressed air that sprays from main burner 12 and flies away reliably.
When weft yarn 40 being cut off by cutter 42, under the tension force effect that acts on weft yarn 40, resulted from the counteractive effect of tension force of this weft yarn 40, weft yarn 40 is often deviate from from main burner 12.Therefore, when weft yarn cuts off, open and close valve 30 is closed, and open and close valve 34 is opened, compressed air regulator 18 adjusted a spot of compressed air are sprayed from main burner 12.Thus, can prevent that weft yarn 40 from deviating from from main burner 12.
(the 2nd embodiment: the air feeder that double-colored loom is used)
Please refer to Fig. 3 and Fig. 4, the pipe arrangement road a of air feeder 46 in air feeder 10, also use the pipe arrangement loop that possesses pipe arrangement road b, this pipe arrangement road b is connected compressed air supply source 14 with the main burner 50 that other weft yarns 48 are flown away, and this air feeder 46 is used for double-colored loom.
Pipe arrangement road b has branch branch road 54 on the pipe arrangement 52 between open and close valve 30 and the compressed air governor 16.From this minute the distributing pipe 56 that stretches out of branch road 54 from minute branch road 54 side downstream, be connected with main burner 50 by compressed air governor 58, converging roads 60 and open and close valve 62 these orders.The pipeline 64 that stretches out from the 3rd air outlet slit of gas tank 14 is connected with converging roads 60 on being configured in the pipe arrangement 66 that stretches out from compressed air governor 58 by compressed air governor 68.
In other words, compressed air governor 58 and 68 utilizes from the pipeline 56 of minute branch road 54 branches with from the pipeline 64 that the 3rd air outlet slit of gas tank 26 stretches out, and is connected side by side with minute branch road 54, open and close valve 30 and gas tank 26.
In air feeder 46, compressed air governor 58 and 68 is devices of adjusting the compressed air discharge, is configured to make compressed air identical with the discharge of compressed air governor 16 and 18 respectively.That is, compressed air governor 58 is set discharge for bigger value, and compressed air governor 68 sets the setting value of discharge than the little value of compression air regulator 58 for.
Like this, the air feeder 46 that double-colored loom is used is except the pipe arrangement road a of above-mentioned air feeder 10, the also pipe arrangement 56 that stretches out from minute branch road 54 by assembling, the pipe arrangement 64, compressed air governor 58 and 68, open and close valve 62 and the main burner 50 that stretch out from gas tank 26, thereby have pipe arrangement road b, and between gas tank 26 and interflow portion 60, dispose compressed air governor 58 and 68 side by side for another main burner 50 usefulness.
In other words, air feeder 46 is from gas tank 26 all shared open and close valve 30 to arbitrary pipeline that main burner 12 and 50 stretches out.Therefore, adopt air feeder 46, owing to have pipe arrangement road a, the b of shared open and close valve 30, so needn't have as the conventional art, open and close valve that number is directly proportional with the main burner number number of comparable conventional art minimizing open and close valve 30.
That is, as shown in table 1, open and close valve number and conventional art when using 2,4,6 main burners, that use in the time of should being configured in the picking between main burner and the compressed air governor are identical.But open and close valve number when using 2,4,6 main burners, that use in the time of should being configured in the cut-out between compressed air supply source and the compressed air governor is 1.Thus, even in air feeder 10, main burner is changed to a plurality ofly, also can suppress the increase of the whole number of open and close valve than conventional art.

The picking scope M of main burner is identical with air feeder 10, carries out in the scope of crankshaft angles θ.In addition, because air feeder 46 is air feeders that double-colored loom is used, be in each picking cycle, in the scope M that picking is sprayed, to carry out by the main burner corresponding with the weft yarn of answering picking so the picking of main burner 12 and 50 is sprayed.
That is, at first among the scope M that the picking during the 1st cycle is sprayed in Fig. 4, under open and close valve 62 pent states, open open and close valve 30 and 34.Thus, a large amount of compressed air sprays from main burner 12, and weft yarn 40 flies away from main burner 12.Compressed air governor 16 and 18 is adjusted to respectively and is fit to the discharge that weft yarn 40 flies away.
Then, among the scope C that the cut-out in Fig. 4 during the 1st cycle is sprayed, under open and close valve 30 and 62 pent states, open open and close valve 34.Thus, spray a spot of compressed air from main burner 12, weft yarn 40 is cut off by cutter 42.Compressed air governor 18 is adjusted to the suitable discharge that weft yarn 40 is cut off.
Then, among the scope M that the picking in Fig. 4 during the 2nd cycle is sprayed, under open and close valve 34 pent states, open open and close valve 30 and 62.Thus, a large amount of compressed air sprays from main burner 50, and weft yarn 48 flies away from main burner 50.Compressed air governor 58 and 68 is adjusted to respectively and is fit to the discharge that weft yarn 48 flies away.
Then, among the scope C that the cut-out in Fig. 4 during the 2nd cycle is sprayed, under open and close valve 30 and 34 pent states, open open and close valve 62.Thus, the compressed air of little discharge sprays from main burner 50, weft yarn 48 be configured in main burner 50 with weave cotton cloth between cutter 70 cut-outs.But weft yarn 48 also can be replaced cutting off for the cutter 70 of yarn side by cutter 42.Compressed air governor 68 is adjusted to the suitable discharge that weft yarn 48 is cut off.
In the illustrated example, air feeder 46 circulates above the 1st cycle and the 2nd cycle repeatedly.
The compressed air governor of using when air feeder 46 utilizes the picking of corresponding weft yarn 40 and 48 16 and 58 and the compressed air governor 18 and 68 used when cutting off can be adjusted the emitted dose of main burner 16 and 50 respectively.Therefore, air feeder 46 not only can be used for the weft yarn of identical type is carried out the occasion of picking, and can be used for different types of weft yarn is carried out the occasion of picking, and the loom of use air feeder 46 can increase the species number of spendable weft yarn.
(the 3rd embodiment: the air feeder that double-colored loom is used)
Please refer to Fig. 5, the pipe arrangement road a of air feeder 72 in air feeder 10, also use the pipe arrangement loop with pipe arrangement road b, this pipe arrangement road b is connected with the main burner 50 that weft yarn 48 is flown away, and this air feeder 72 can be used for double-colored loom.
Owing to directly do not divide branch road 76 to be connected, so it is just roughly the same with the flow that is supplied in open and close valve 34 to be supplied in the compressed-air actuated flow of open and close valve 62 with the interflow by the compressed air governor 58,68 among Fig. 3.Therefore, at this moment, air feeder 72 is suitable for respectively weft yarn 40 and 48 with identical type from main burner 12 and 50 looms that carry out picking.
(the 4th embodiment: the air feeder that the double-colored loom of the auxiliary main burner of band is used)
Please refer to Fig. 6, air feeder 78 is except pipe arrangement road a, the b of air feeder 46 shown in Figure 3, also use to have the pipe arrangement road d that is connected with 82 with the compressed air governor 80 that sprays usefulness all the time, the pipe arrangement loop of e, and use doubly-linked main burner 84 with main burner 12 and 50.
The pipe arrangement that plays common stream effect 86 that stretches out to compressed air governor 18 and 68 from gas tank 26 passes through to divide branch road 88 to compressed air governor 18 and 68 branches.The pipe arrangement 44 that stretches out from compressed air governor 18 and 68 air outlet slit is connected with converging roads 32 and 60 respectively with 90.
On the pipe arrangement 86 between gas tank 26 and the branch branch road 88, dispose branch branch road 92.From this minute the pipe arrangement 94 and 96 that stretches out of branch road 92 respectively by compressed air governor 80 and 82 and be configured in open and close valve 34 and 62 with main burner 12 and 50 between pipe arrangement 98 and 100 on converging roads 102 and 104 be connected.
Air feeder 78 has the branch branch road 106 and 108 that is configured on pipe arrangement 98 and 100, and pipe arrangement 98 and 100 stretches out to main burner 12 and 50 from converging roads 102 and 104.Be connected with 50 with main burner 12 respectively from minute branch road 106 and 108 branches and the side's that stretches out pipe arrangement, the opposing party's pipe arrangement 110 is connected with 116 with auxiliary main burner 114 respectively with 112.
Therefore, air feeder 78 has by compressed air governor 80 and 82 and 26 compressed and supplied air of gas tank are supplied to main burner 12 and 50 and pipe arrangement road d, the e of auxiliary main burner 114 and 116.Pipe arrangement road d and e will be not air by open and close valve 30,34,62 be supplied in main burner 12,50 and auxiliary main burner 114,116.
