Description
Technical field
The present invention relates to a kind of in the air injection type loom; Particularly comprising that wefting insertion is with main burner with along many auxiliary jets of wefting insertion path configurations; Through each auxiliary jet group from the beginning that supplies the yarn side in order in the predefined time property taken over aerojet; The air injection type loom that the weft yarn that boosting penetrates from main burner flies, the weaving method the when yarn that dyes earlier is used as weft yarn.
Background technology
General air injection type loom, as shown in Figure 5, fly from the weft yarn Y that main burner 1 penetrates for boosting, in the fabric width zone, (exist in the fabric width direction in the scope of longitude yarn row), along the wefting insertion path configurations many auxiliary jets 3 are arranged.
In well-known air injection type loom, these auxiliary jets 3 constitute: from supply the yarn side begin be divided into a plurality of one group by putting in order, the auxiliary jet 3 that each group is comprised is connected with shared electromagnetic switch valve 3a, side by side carries out aerojet.And each group (auxiliary jet group) of auxiliary jet 3 is set at: as shown in Figure 6 predefined during, from supplying the beginning property the taken over aerojet in order of yarn side.In addition, in chart shown in Figure 6, transverse axis is the anglec of rotation (degree in crank angle) of loom main shaft, and the longitudinal axis is corresponding to the distance of the fabric width direction that begins from the main burner front end.
Following content shown in the chart of this Fig. 6: the 1G in the chart, 2G, 3G ... Corresponding to each auxiliary jet group, by supplying the 1G that is expressed as of yarn side, by putting in order; Its next door be expressed as 2G; Again the next door be expressed as 3G, by that analogy, many auxiliary jets 3 are divided into 8 auxiliary jet groups.And, represent with bar chart with mode between the injection period of each auxiliary jet group corresponding to degree in crank angle.The straight line of oblique this bar chart of crosscut is represented the hypothetical flight line of weft yarn Y, and in illustrated example, weft yarn Y is set at 80 ° of degree in crank angles and begins flight, and be 240 ° of degree in crank angles the target time of advent that arrives the anti-assigned position that supplies the yarn side.And, between the injection period of the main burner 1 that the strip line that is recorded in this chart below is represented to set (70 °～180 ° of degree in crank angles).
Between the injection period of above-mentioned main burner 1 and auxiliary jet 3 (injection beginning time with spray concluding time) be set in the wefting insertion control part 5 shown in Figure 5 by not shown input setting apparatus.Input has signal in the wefting insertion control part 5, and this signal is represented the anglec of rotation θ that main shaft Ms rotates a circle from the encoder EN of the main shaft Ms that is connected in loom.
Wefting insertion control part 5 bases are from the injection beginning time and the injection concluding time of anglec of rotation θ and main burner 1 that sets and the auxiliary jet 3 of the main shaft Ms shown in the signal of encoder EN; In the electromagnetic switch valve 1a of main burner 1 and be connected in the Kai Heguan of the electromagnetic switch valve 3a of each auxiliary jet group, make main burner 1 and auxiliary jet 3 between the whole injection period that sets, carry out injection action through control connection.In addition; Symbol 1b, 3b represent the pressure regulator between compressed air source As and each electromagnetic switch valve 1a, 3a among the figure; Be fed into the compressed-air actuated pressure in the main burner 1 by pressure regulator 1b adjustment, and be fed into the compressed-air actuated pressure in each auxiliary jet group by pressure regulator 3b adjustment.
From supply yarn body 7 derivative weft yarn Y; A wefting insertion amount (1 latitude amount) temporarily leaves in the length measuring weft storing device 9; The weft yarn Y of the 1 latitude amount that this is stored is drawn from length measuring weft storing device 9 through the tractive force of the compressed air (injection air) that main burner 1 is sprayed, and by wefting insertion.In this wefting insertion process, each auxiliary jet 3 sprays compressed air towards the weft yarn Y that penetrates from main burner 1 and fly, through the effect boosting weft yarn Y flight of this aerojet.And after this wefting insertion finished, weft yarn Y was beaten up at the fell of the W that weaves cotton cloth by reed R, and afterwards, the confession yarn cutter 11 that is arranged on confession yarn side between W and the main burner 1 cuts off weaving cotton cloth.With this, the weft yarn Y with 1 latitude amount length becomes the state that is inweaved the W that weaves cotton cloth.
Yet, in aforesaid wefting insertion process, be not the integral body that acts on the weft yarn Y of 1 latitude amount to the above-mentioned injection air (compressed air) of weft yarn Y generation effect, but only act on the part of the anti-confession yarn side of wefting insertion direction in its total length.In other words, the weft yarn Y of 1 latitude amount is not the effect of accepting injection air in its integral body, is positioned at that the part that supplies the yarn side is not then accepted the effect of injection air fully under by the state of wefting insertion and by wefting insertion.Its result, for example denim etc. when using the yarn that dyes earlier to weave as weft yarn Y, can produce following quality problems among the woven W that weaves cotton cloth of institute, is promptly supplying yarn side sections and the anti-yarn side sections that supplies to produce aberration.Specific as follows.
As stated; In general in recent years air injection type loom; Between the injection period of each auxiliary jet group be: with from the beginning that supplies the yarn side in order the mode of the property taken over aerojet set injection beginning period; Corresponding with it, spray tail end and also be set at the auxiliary jet group FEFO injection that is positioned at confession yarn side.
Fig. 7 is the figure of the relation of the injection of weft yarn Y and each auxiliary jet group in the expression wefting insertion process, and has represented to be recorded in the wefting insertion state (wefting insertion length) of weft yarn Y in each degree in crank angle of the leftmost side among the figure and the spray regime (solid injection is arranged) of each auxiliary jet group.Identical with Fig. 6, the figure shows the example when the auxiliary jet group is 8, the ellipse representation auxiliary jet group of executing hachure with oblique line among the figure is being carried out aerojet.In addition, illustrated degree in crank angle has been put down in writing during the wefting insertion in (80 °～240 ° of degree in crank angles) whenever the degree in crank angle at a distance from 20 °.That is to say, among this figure towards longitudinally the below wefting insertion carry out gradually, each horizontal position is corresponding to each position of the auxiliary jet group in the fabric width direction of loom.
It can also be seen that from this figure in the total length of the weft yarn Y of 1 latitude amount of wefting insertion, the weft yarn part a of latter half of (leaning on the anti-yarn side that supplies than central portion) accepts the effect from the injection air of auxiliary jet 3 at least one period in during wefting insertion.Particularly accept the effect of injection air during the fore-end of weft yarn whole in wefting insertion.
On the other hand, in the total length of the weft yarn Y of 1 latitude amount, the weft yarn part b of first half (than central portion by supplying the yarn side) accepts the effect from the injection air of auxiliary jet in during wefting insertion hardly.In addition, in illustrated example, main burner 1 carries out aerojet till 180 ° of the degree in crank angles.Therefore, even first half b, near the weft yarn part the central portion is still accepted the effect from the injection air of main burner 1.But in the weft yarn part that supplies the yarn side is during wefting insertion, do not accept the effect of injection air than it fully, and inweaved among the W that weaves cotton cloth.
In addition, when the yarn that dyes is earlier used as weft yarn Y, be known that the effect of in by the process of wefting insertion, accepting injection air through this weft yarn, the tomentum on weft yarn Y surface is dispelled.But; As stated, in the weft yarn Y of 1 latitude amount of wefting insertion, the anti-part that supplies the yarn side is accepted the effect of injection air; In contrast; The major part of confession yarn side is not then accepted the effect of injection air fully, and therefore, weft yarn Y is inweaved among the W that weaves cotton cloth with anti-confession yarn side and the fine hair attachment state different state that supplies the yarn side surface.Its result causes the woven W of weaving cotton cloth of institute supplying the yarn side different with the anti-yarn side tone that supplies.
Disclose a kind of technology in the patent documentation 1, made each auxiliary jet group carry out aerojet with the mode that is different from example shown in Figure 6.Specifically, for each auxiliary jet group, promptly be used in finish between each injection period of wefting insertion after, lean on most the anti-injection that supplies the auxiliary jet group of yarn side finish before in the prescribed period of time between the time of beating up, each auxiliary jet group is sprayed again.
The technology of this patent documentation 1 (prior art) purpose is: improve the tractive force that injection air produced from auxiliary jet that acts on weft yarn when wefting insertion finishes, and improve weft yarn at the tension force that is inweaved when weaving cotton cloth.According to this prior art; With auxiliary jet group as shown in Figure 6 only the situation of the property taken over aerojet compare; Also act on the weft yarn part that supplies the yarn side in the weft yarn of 1 latitude amount from the injection air of auxiliary jet, therefore, reduced aforesaidly supplying yarn side and the anti-yarn side that supplies to produce tone difference.

Yet, even adopted above-mentioned prior art, still can produce following problem, promptly the part that differs greatly of woven local residual tone of weaving cotton cloth.This is because even all auxiliary jets have all carried out aerojet, its injection air does not act on by the total length of the weft yarn of wefting insertion yet.Specific as follows.
In the formation of general air injection type loom, auxiliary jet is configured in the zone of aforesaid fabric width, can not be near the weft yarn partial action injection air the fabric end by the auxiliary jet that supplies the yarn side even be positioned at.That is to say, even be positioned at by supplying the auxiliary jet of yarn side, owing to be arranged on the inboard (center side of weaving cotton cloth) of the fabric end position in the fabric width direction; And; For the flight of boosting weft yarn, be arranged to air is sprayed towards the downstream of wefting insertion direction, therefore; For near the weft yarn part the fabric end that supplies the yarn side, do not produce effect from the injection air of auxiliary jet.
Therefore, if be purpose like prior art with the tractive force that raising acts on weft yarn, only the aerojet of auxiliary jet is just enough, but to being inweaved on the weft yarn mass action injection air this point of weaving cotton cloth, this prior art is abundant not enough.The state that its result causes near the part of weft yarn fabric end to stay many fine hair is inweaved weaves cotton cloth, and it is different that this part and other parts are compared tone.
In addition; Can consider to dispose like this each auxiliary jet 3; For near the injection air of the weft yarn partial action the fabric end from auxiliary jet 3; Make to be present in and can the position of above-mentioned weft yarn partial action injection air to be that is to say by the auxiliary jet 3 that supplies the yarn side, be present in the position of leaning on main burner 1 side than the fabric end that supplies the yarn side.But such formation not only increases the quantity of auxiliary jet 3, and possibly cause the waste of injection air, and wefting insertion is produced harmful effect.Specific as follows.
Originally, during the setting of auxiliary jet 3 in during wefting insertion, be weft yarn Y flight the carrying out aerojet that boosting penetrates from main burner 1.On the other hand, from the spray-hole of main burner 1 near fabric end, undertaken by the auxiliary jet group that supplies the yarn side at least aerojet during, from the injection air of main burner 1 fully to weft yarn Y generation effect.Therefore, the part that the injection air that auxiliary jet 3 is sprayed acts near the weft yarn Y the fabric end that is positioned at confession yarn side not only there is no need on boosting weft yarn Y flight this purpose, and can cause wasting injection air.On the contrary, in above-mentioned formation, after wefting insertion had just begun, the injection air that auxiliary jet 3 sprays was in the state of interfering the injection air that main burner 1 just sprayed, and therefore, possibly upset from the flowing of the injection air of main burner 1, and wefting insertion is produced harmful effect.
Summary of the invention

Illustrated part representes around the leading section of main burner 1 that main burner 1 is arranged on the reed frame Rh, by main burner support 1c supporting leading section and base end part (not shown).Reed frame Rh is used to support reed R, shakes by rocker (not shown) supporting and along with the rotation of rocker, makes reed R carry out beating motion with this.
, fly in the weft yarn guiding groove Rp that the reed wire r with reed R forms along with aerojet from the weft yarn Y of main burner 1 break-through from main burner 1, and, in the opening that forms by warp thread T by wefting insertion.Therefore, this weft yarn guiding groove Rp is the wefting insertion path.
On reed frame Rh, be provided with many auxiliary jets 3 (auxiliary jet 3 that leans on confession yarn side most only is shown among the figure) along the wefting insertion path by nozzle supporter 3b supporting.These auxiliary jets 3 are connected in above-mentioned electromagnetic switch valve 3a (Fig. 5) by air supply pipe 3c, and the Kai Heguan by wefting insertion control part 5 control electromagnetic switch valve 3a is carrying out aerojet like Fig. 6 between illustrative predefined injection period with this.
In having the air injection type loom that constitutes as stated,, be provided with near the pilot jet 10 of leading section that spray-hole is positioned at main burner 1 among the present invention for the weaving method of embodiment of the present invention.
In Fig. 1, the example shown in 2, pilot jet 10 is the same with auxiliary jet 3, is arranged on the reed frame Rh through nozzle supporter 12.Illustrated pilot jet 10 with tubular part (for example: copper pipe) form, between base end part that is supported by nozzle supporter 12 and leading section, bend to circular arc is.
Specifically; This pilot jet 10 forms following shape: base end part is extending with the roughly the same direction of the axis of auxiliary jet 3; And bend at pars intermedia circular-arc, and, bend to circular-arc part to the part angulation the spray-hole of front end from this; See reed R from the front, approaching towards front below main burner 1 with respect to main burner 1.Therefore, the direction that this auxiliary air nozzle 10 carries out aerojet is the injection direction of main burner 1, promptly forms some angles with respect to the wefting insertion direction of weft yarn Y and tilts, can be for the end effect injection air of the confession yarn side of the weft yarn Y that penetrates from main burner 1.
In addition, pilot jet 10 is provided with the angle of inclination with respect to main burner 1 of the length dimension of suitable above-mentioned base end part, the amount of bow that bends to circular-arc part and leading section so that its spray-hole around the leading section of main burner 1 near the position of main burner 1.
The installation site of nozzle supporter 12 relative reed frame Rh can be changed on the bearing of trend of reed frame Rh.Therefore, through the installation site of change nozzle supporter 12, can adjust pilot jet 10 positions in the fabric width direction (bearing of trend of reed frame Rh).Pilot jet 10 is configured to: is fastening with the pass of injection direction the position of its spray-hole, be can to from the fabric end of the confession yarn side of fabric width direction in the position that acts on injection air effectively by the part of the weft yarn Y the aerojet zone of action of the auxiliary jet 3 that supplies the yarn side.
In addition, in illustrated example,, make the position of spray-hole and the roughly the same mode in spray-hole position of main burner 1 dispose pilot jet 10 with in the wefting insertion direction.But; The position of the pilot jet 10 in the wefting insertion direction is according to position (with the distance of main burner 1) and the injection direction of its spray-hole around main burner 1 (under the situation in illustrated example; Angle of inclination for fore-end) suitably set and get final product, can consider the position of the leading section scope of main burner 1, from the front end of main burner 1 to the position of the fabric end of confession yarn side.
This pilot jet 10 connects through the air supply pipe 14 special-purpose electromagnetic switch valve (not shown) different with the electromagnetic switch valve 3a that is connected with auxiliary jet 3.This electromagnetic switch valve is the same with the electromagnetic switch valve 3a that is connected in auxiliary jet 3, through being opened and closed by 5 controls of wefting insertion control part in the predefined time, between the injection period of hope, carries out aerojet.In addition; In the present embodiment; As shown in Figure 3, be set between the injection period of pilot jet 10 from 240 ° of degree in crank angles to 330 ° of degree in crank angles, degree in crank angle is for 240 ° the target time of advent of the weft yarn Y that sets; As the time that wefting insertion finishes, 330 ° of degree in crank angles are that warp thread T becomes the state of remaining silent and weft yarn Y is interweaved by warp thread T.
According to above air injection type loom; Finish from wefting insertion and time (240 ° of degree in crank angles) that weft yarn Y stops to move to the time (330 ° of degree in crank angles) that weft yarn Y is interweaved by warp thread T; The relative fabric end of the confession yarn side in the fabric width direction and leaning on the auxiliary jet 3 that supplies the yarn side to carry out the part of the weft yarn Y between the zone of action of aerojet, the compressed air generation effect of pilot jet 10 injections most.With this; In the time that wefting insertion finishes, can also act on compressed air to the part that is positioned at the weft yarn Y beyond the zone of action that auxiliary jet 3 carries out aerojet, therefore; When employed weft yarn Y was the yarn that dyes earlier, the state that can make the above-mentioned part that inweaves the weft yarn Y before weaving cotton cloth was near other parts.
In addition; In Fig. 1, the example shown in 2; The pilot jet that use is bent to form tubular parts such as copper pipe, but the formation of pilot jet of the present invention is not limited in this, for example also can use as pilot jet 20 with nozzles auxiliary jet 3 identical formations as shown in Figure 4.
Be not limited between the injection period of pilot jet during whole the time that is interweaved by warp thread T from time that wefting insertion finishes to weft yarn Y, but also only during the part in during this period.That is to say; As stated; Can be during this section from the time to the time that weft yarn Y is interweaved by warp thread T that wefting insertion finishes, the fine hair attachment state of considering weft yarn Y and the compressed-air actuated pressure that is sprayed etc. be suitably set between the injection period of pilot jet and are got final product.
In above-mentioned explanation, will be for the wefting insertion control that is used for loom etc. and the time that finish as wefting insertion the target time of advent (setting value) of predefined weft yarn Y, but possibly depart from above-mentioned setting value the time of advent of the weft yarn Y in the actual wefting insertion.So; With the time of above-mentioned setting value as the wefting insertion end; During whole the time to the time that weft yarn Y is interweaved by warp thread T that finishes from wefting insertion, make under the situation that pilot jet sprays, but the times prior that also is set in this wefting insertion end makes pilot jet begin aerojet preparation property.In addition, the front end that also can detect weft yarn Y has arrived the assigned position of anti-confession yarn side, and, make pilot jet begin to spray according to this detection, replace the injection beginning time of setting pilot jet according to above-mentioned setting value.And, also can after the time that weft yarn Y is interweaved by warp thread T, make that pilot jet continues to spray a period of time complementaryly.
In above-mentioned explanation; Air injection type loom as prerequisite is: many auxiliary jets along the wefting insertion path configurations begin to be divided into a plurality of one group by putting in order from supplying the yarn side; And the auxiliary jet in each group is connected with shared electromagnetic switch valve; But being not limited in this, also can be that auxiliary jet is connected with 1 pair 1 of electromagnetic switch valve, can set between injection period each auxiliary jet.Even but this situation; Auxiliary jet finally is to be configured in the fabric width zone (to exist in the fabric width direction in the scope of longitude yarn row); And the mode of the flight of the weft yarn that penetrates from main burner with boosting was set between injection period; Be arranged on than the fabric end that supplies the yarn side and lean on the main burner side, and what carry out injection action in above-mentioned specified time limit is pilot jet of the present invention.
And the present invention is not limited in any one embodiment of above-mentioned explanation, also can carry out various changes in the scope of the inventive concept not breaking away from.
