Now details are as follows with the working method of weft yarn fixed length storage Weft handling device W.
The weft yarn 3 that involves from weft yarn supply part or bobbin 2(as shown in Figure 2) guides to the weft yarn fixed length part 11 of weft watering tube 1 and around thereon, is pushed down by pressure roller 10 by thread-carrier 26, and wherein weft yarn 3 is supplied with continuously according to the predetermined speed that weft watering tube 1 rotates.The weft yarn 3 of Gong Geiing is guided and is conducted on the storage latitude part 12 of weft watering tube 1 by thread-carrier 23 like this.Then, weft yarn 3 passes fixedly keeps tube 13 and the fixing gap between the housing 7 15,16, and is directed to thread-carrier 17.Then, weft yarn 3 is introduced Weft-insertion nozzle 22 by yarn gripper 21, is introduced into the race of warp thread.
In the above-mentioned course of work, by the weft yarn 3 that pressure roller 10 is pushed down, the rotating speed according to the weft watering tube that is rotated axle 4 drivings feeds to and enters gas circuit 6 with predetermined speed.The weft yarn 3 that infeeds like this under the effect of air flow, is forced to rotation with the identical direction of weft watering tube 1 rotation direction in gas circuit 6.Consequently, weft yarn 3 some circles of on the storage latitude part 12 of weft watering tube 1, reeling.
When reaching preset time, lead latitude or wefting insertion begins, so that the weft yarn 3 that is wound on the weft watering tube 1 storage latitude part 12 is pulled.At this moment, the weft yarns of further being supplied with by fixed length part 11 3 by Weft-insertion nozzle 22, are drawn by fixing weft yarns carrier 23, store on the latitude part 12 and be not wound on.When finishing guide, lead the weft yarn 3 of latitude next time, be wound in the same manner described above on the storage latitude part 12 of weft watering tube 1.Can understand that weft watering tube 1 is to rotate under the state of its end wall 24 near the end wall 25 of fixedly keeping tube 13.
In gas circuit 6 under the effect of air-flow, in weft yarn 3 rotary courses, infeed the gas of gas circuit 6 through air inlet 18A, the gas circuit 6 of flowing through, emits through exhaust outlet 19 around a circle then with the identical direction of weft watering tube 1 rotation direction.This discharging of air-flow, a plurality of through holes 20 on weft watering tube end wall 24 only in the axis rotating process of the moving axis 4 that rotates, just carry out when exhaust outlet 19 on the tube 13 meets with fixedly keeping.
Therefore, enter the air-flow of gas circuit 6,, after the gas circuit of flowing through 6 about circles, and before arriving air inlet 18A, emitted immediately with the identical direction of weft watering tube 1 rotation direction by air inlet 18A.Like this, prevent the reduction of gas circuit 6 internal gas pressures, thereby can improve the speed of air-flow in the annular gas channel 6.This just might improve the running speed of loom, and then has improved the performance of loom.In this connection, if air-flow is discharged, be discharged the gas circuit downstream of position so at air-flow in the way that the one circle flows, the speed of air-flow will descend inevitably.
According to the foregoing description, the special positioning relation between exhaust outlet 19 and the air inlet 18A is limited according to the fixing tube 13 of fixedly keeping.So, be used for rotating the air-flow of weft yarn 3, it had flowed an about circle along gas circuit after, bump was discharged before the new air-flow that air inlet 18A flows into immediately.So that the discharge orifice 19 that air communication is crossed requirement emits.Therefore this does not just require too much throughput, does not need to increase the air blast that air-flow in the gas circuit 6 is provided or the power of similar devices, thereby reaches energy-conservation purpose.
As shown in Figure 1, weft watering tube 1 comprises the first section A and second section B.The first section A has most of adjacent frustum or the tapered surface with fixed length part 11 and storage latitude part.Second section B is included in the tapered surface T that weft watering tube 1 top forms.Verified, the first section A plays a part to make each adjacent weft yarn to be separated from each other, and second section B plays a part to assist the weft yarn on the storage latitude part 12 to lead to Weft-insertion nozzle 22.Therefore, preferablely be, the first section A is low relatively with respect to the drafting resistance of weft yarn, and second section B is high relatively with respect to the drafting resistance of weft yarn.Be appreciated that the weft yarn on the first section A, its tension force is relatively little, even so that its surface softly can not produce wearing and tearing yet, and the weft yarn on second section B, its tension force is big relatively, if so that its surface not hard, the trend of the wearing and tearing of producing is just arranged.
Therefore, have under the situation of similar face situation at the first and second section A, B, will make sacrifice for one in them, therefore, it is difficult obtaining good working order.Given this, according to present embodiment, the first and second section A, B are provided with surface appearance, material, hardness and/or surface treatment respectively.Such setting also will be according to the yarn types as weft yarn.In the present embodiment, weft watering tube 1 is made of aluminum, and wherein the first section A have alumite face coat and polished surface, and second section B applies with ceramic coating.Second section B can be made by stainless steel, does not carry out surface treatment (or a hard chrome coating or a ceramic coating arranged).Such surface constitutes, and is particularly suitable for the weft yarn that nylon or analog are made.
