The specific embodiment
Hereinafter with reference to the loom with multicolor weft insertion device of Fig. 1 to Fig. 5 description according to first embodiment of the invention.In the first current embodiment, pile fabric loom is as loom.Referring to Fig. 1, in this loom the place ahead of reeling, upside is then corresponding to the loom rear of broadcasting warp at this corresponding to knitted fabric for the downside of diagrammatic sketch.In addition, the left side of diagrammatic sketch is corresponding to the left side of loom, and the right side is then corresponding to the right side of loom.
Referring to Fig. 3, with the schematically illustrated pile fabric loom of its side view, this loom has ground warp axle 10, and ground warp axle 10 is broadcasted ground warp on the controller CG and broadcasted motor MG and drive and be rotated by being electrically connected to ground warp.The body warp T that broadcasts from ground warp axle 10 moves through arc back guide 11 and tension roller 12, and through heddle (heald) 13 and special-shaped reed spare 5.Knitted fabric W reels around fabric roller 19 by stretch rod (expansion bar) 15, surperficial roller 16 and guiding roller 17 and 18.
Extend upward on the frame 20 that bar 21 is installed to loom, and locate to support pivotally tension roller 12 in the top.Tension roller 12 is promoted by any suitable pushing mechanism (not shown), forms the tension variation of operating the body warp T that causes so that absorbed because of shed open by negative easing motion.Extension rod 22 is installed on the frame 20 downwards, and rod member 23 is pivotally connected on the lower end of downward extension rod 22.Load transducer 24 is installed in the tension force that is used for the body warp T of detection effect on tension roller 12 on the rod member 23, and is connected to ground warp electrically and broadcasts on the controller CG.Ground warp is broadcasted controller CG and can be operable to based on predetermined benchmark tension value with by load transducer 24 detected warp tension information and control the speed that ground warp is broadcasted motor MG.
Pile is positioned at the top of ground warp axle 10 through axle 25.Pile through axle 25 by being electrically connected to pile through broadcasting pile on the controller CP through broadcasting motor MP and drive and rotating.Broadcast and move through through axle 25 from pile and turn to the pile warp TP of roller 26, tension part 27 and fluffing motion roller 28 to pass heddle (heald) 13 and special-shaped reed spare 5.
Turn to roller 26 rotatably by frame 20 supportings.Turn to roller 26 not have a pair of element (not shown) to be detected with place, the contacted opposite end of pile warp TP at it.A pair of being positioned to above-mentioned paired element to be detected near switch 31 (only illustrating) is to face relation.Paired can operate the rotation that turns to roller 26 with detection near switch 31, and also generates rotation detection signal for pile through broadcasting controller CP.Tension part 27 is by flat spring 32 supportings, and flat spring 32 is by axle 30 supportings that are installed on the frame 20.In this arranges, form the tension variation of operating the pile warp TP that moves through tension part 27 that causes because of shed open and absorb by flat spring 32 distortion.Bar 14 with load transducer 29 is fixed on the end of axle 30.Load transducer 29 can be operated the tension force with detection pile warp TP, and generates detection signal for pile through broadcasting controller CP.
Pile can be operated with based on controlling pile through broadcasting the speed of motor MP by the comparison of load transducer 29 detected warp tension information and predetermined benchmark tension value with by paired near switch 31 detected rotation detection signals through broadcasting controller CP.Rotatably by the far-end supporting of rocking bar 34 upper arm, this rocking bar 34 is supported by axle 33 fluffing motion roller 28 pivotally.The underarm of rocking bar 34 is pivotally connected on the rod member 23.
Caliper intermediate bar 35 is in that place, the observed centre position of vertical direction is installed on the rotatable shaft 36 along loom, and the top that is positioned at caliper intermediate bar 35 as the fluffing motion 37 of fell moving member of the present invention.Fluffing motion 37 has the decelerator (reducer) that comprises ball screw mechanism, roller gear or planetary gear type or the driver element (not shown) of cam mechanism therein.Driver element is driven by the fluffing campaign CD-ROM drive motor MT that is electrically connected on the fluffing motion controller CT of himself.When the work of fluffing motion 37, the drive rod 39 that is installed on the driving shaft 38 that is connected on the driver element reciprocally pivots along alternating direction.
Therefore, the reciprocal pivotal movement of intermediate bar 35 causes that by rod member 45 rocking bar 44 shakes, and passes to stretch rod 15 and temple 9 thereby will fluff to move on the direction identical with tension roller 12 and fluffing motion roller 28.Fabric roller 19 is driven by the coiling motor MW that is electrically connected on the winding controller CW, and knitted fabric W is used to reel.
Loom controller CR controls the work of loom CD-ROM drive motor MR and is connected on the rotary encoder 46, and this rotary encoder 46 can be operated to detect the position, angle of loom.Loom controller CR stores the data of position, loom angle therein.Shown in the arrow line among Fig. 3, loom controller CR is connected to weft inserting apparatus 2, ground warp is broadcasted controller CG, pile through broadcasting on controller CP, fluffing motion controller CT and the winding controller CW.Loom controller CR generates activation signal for Weft insertion nozzle 2A-2H, and also for ground warp broadcast motor MG, pile provides the driving signal through broadcasting motor MP, fluffing motion CD-ROM drive motor MT and coiling motor MW.Although ground warp is broadcasted motor MG, pile comprises servo motor through broadcasting motor MP, fluffing motion CD-ROM drive motor MT and coiling motor MW, they can be any other electro-motor.
In the pile knitting of pile fabric loom, loom controller CR reads the pile Weaving pattern, and generates for pile through broadcasting the activation signal of controller CP and fluffing motion controller CT.Therefore, during the loose weft in the pile knitting, fluffing motion 37 impel tension roller 12, fluffing motion roller 28, stretch rod 15 and temple 9 forward or the right side in Fig. 3 move, thereby fell W1 is moved to the position shown in the dotted line among Fig. 3.During the bright pick in the pile knitting, fluffing motion 37 also impel tension roller 12, fluffing motion roller 28, stretch rod 15 and temple 9 backward or the left side in Fig. 3 move, thereby fell W1 is back to by the stop position shown in the solid line among Fig. 3.
Hereinafter will be described in detail in the edge Weaving pattern that is provided with in the pattern controller 47.Usually, fell W1 is fixed on parallel stop position place, is used at edge knitting knitted fabric W.In current embodiment, when selected Weft insertion nozzle is touched in the edge knitting and when introducing weft yarn Y, just by using fluffing motion 37 to make fell W1 move forward preset distance.
As shown in Fig. 1 and Fig. 2, arranged eight Weft insertion nozzle 2A-2H, that is, and the past of loom backward or from after four row's nozzles of seeing of forward direction, and two row's nozzles of on the vertical direction of loom, seeing.Referring to Fig. 4 of the motion that has shown fell W1, show the position relation between the outlet of eight Weft insertion nozzle 2A-2H and the body warp T (or pile warp TP) that opens wide.Although the outlet of Weft insertion nozzle 2A-2D is positioned to remotely warp thread T (or pile warp TP), the outlet of Weft insertion nozzle 2E-2H is positioned to than the outlet of Weft insertion nozzle 2A-2D warp thread T (or pile warp TP) closer.Having outlet is positioned to outlet than Weft insertion nozzle 2A-2D closely Weft insertion nozzle 2E and the 2F of warp thread T (or pile warp TP) seldom can not introduce weft yarn Y. Weft insertion nozzle 2G and 2H (its outlet in the outlet of Weft insertion nozzle 2A-2H the most closely warp thread T (or pile warp TP)) can not introduce weft yarn Y easily.
When any one in selecting Weft insertion nozzle 2E-2H weaves the edge Weaving pattern, another program of the displacement of the program of work of indication fluffing motion 37 and indication fell W1 is set according to selected Weft insertion nozzle (or from fell W1 distance), and the program of the order of Weft insertion nozzle 2A-2H is selected in indication.Fig. 5 shows the example in the part of work of braiding edge Weaving pattern, wherein, with this kind select progressively Weft insertion nozzle 2G, 2F, 2H and 2C come wefting insertion, as by shown in the horizontal axis.When selecting, just fell W1 is provided with relatively large displacement X1 near the Weft insertion nozzle 2G of fell W1 or 2H.When selecting during from the farther Weft insertion nozzle 2F of fell W1, just fell W1 to be provided with less relatively displacement X2 than Weft insertion nozzle 2G and 2H.Therefore, when selecting Weft insertion nozzle 2F,, reduced the driving load of fluffing motion 37 than the situation of fell W1 displacement X1.When selecting than Weft insertion nozzle 2F during from the farther Weft insertion nozzle 2C of fell W1, the displacement of fell W1 is zero, and fell W1 is fixed on by the stop position place shown in the X3.Therefore, when selecting Weft insertion nozzle 2C, do not provide work order for fluffing motion 37.
That is to say that when selecting Weft insertion nozzle 2A-2D, the loom controller CR that reads the edge Weaving pattern does not provide instruction in order to mobile fell W1 to fluffing motion 37.When selecting Weft insertion nozzle 2E and 2F, loom controller CR indication fluffing motion 37 makes fell W1 displacement X2.When selecting Weft insertion nozzle 2G and 2H, loom controller CR indication fluffing motion 37 makes fell W1 displacement X1.Compare with the fell W1 displacement in the pile knitting shown in the dotted line X4 among Fig. 5, the fell W1 displacement among the current embodiment shortens.The displacement of this shortening of fell W1 allows that multicolor weft insertion device follows the high speed rotation of loom.
The work of the pile fabric loom in the edge knitting is hereinafter described with reference to Fig. 4 and Fig. 5.When loom work when the pile knitting becomes edge knitting and pattern controller 47 and selects Weft insertion nozzle 2G then, loom controller CR indication fluffing motion 37 makes fell W1 displacement X1.Be that fluffing motion 37 moves forward tension roller 12, fluffing motion roller 28, stretch rod 15 and temple 9 accordingly.Therefore, in Fig. 1 and Fig. 4, fell W1 moves forward distance X 1, thereby increased the vertical space of (or between top pile warp TP sheet and bottom pile warp TP sheet) between top body warp T sheet and the bottom body warp T sheet in the position of contiguous Weft insertion nozzle 2G outlet, this makes by the wefting insertion of nozzle 2G stable.
When finishing by the wefting insertion of nozzle 2G, fluffing motion 37 moves tension roller 12, fluffing motion roller 28, stretch rod 15 and temple 9 backward, thereby fell W1 is returned in Fig. 5 by the stop position shown in the X3 (referring to the solid line among Fig. 1 and Fig. 4), at this place, weft yarn Y is beaten up to fell W1 by special-shaped reed spare 5.In the case, the Return-ing direction of the stop direction of special-shaped reed spare 5 and fell W1 has obtained the bigger power of beating up so that be retained in situation about locating the fixed position than fell W1 toward each other.The so big power of beating up is particularly very effective in the very high parallel of needs beats up the edge braiding of density.
Similarly be that when selecting Weft insertion nozzle 2F, fell W1 moves forward distance X 2.When finishing by the wefting insertion of nozzle 2F, fell W1 returns in Fig. 5 by the stop position shown in the X3, and at this place, weft yarn Y is beaten up to fell W1 by special-shaped reed spare 5.When selecting Weft insertion nozzle 2H, fell W1 moves forward distance X 1.When finishing by the wefting insertion of nozzle 2H, fell W1 returns stop position X3, and at this place, weft yarn Y is beaten up to fell W1 by special-shaped reed spare 5.When selecting Weft insertion nozzle 2C, then carry out normal wefting insertion and beat up, and fell W1 does not move.
The first embodiment of the present invention provides following advantageous effects.
(1) in first embodiment, wherein, eight Weft insertion nozzle 2A-2H are fixed on the slay 1, when the Weft insertion nozzle 2E-2H near fell W1 is used for wefting insertion, by using fluffing motion 37 that fell W1 is moved forward, thereby increase the vertical distance that separates between the outlet of Weft insertion nozzle 2E-2H and top body warp T sheet and bottom body warp T sheet (or pile warp TP).Increase through the motion of line tension, and the warp looseness correspondingly reduces owing to fell W1.Therefore, warp thread T (TP) tangles with weft yarn Y hardly, and makes wefting insertion stable.It is very durable to have the weft inserting apparatus 2 that is fixed on eight Weft insertion nozzle 2A-2H on the slay 1.
(2) since the Return-ing direction of the stop direction of special-shaped reed spare 5 and fell W1 toward each other, so the power of beating up increases, this is very effective when the very high parallel of braiding needs beats up the fabric of density.
(3) in according to the first embodiment of the present invention, the fluffing motion 37 that is generally used for the pile knitting also is used for the edge knitting, so that fell W1 is moved, thereby uses the fluffing motion 37 with functional reliability effectively.Therefore, as fell moving member of the present invention, loom according to the present invention need not independent mechanism and is used at the mobile fell of edge knitting by the motion 37 that will fluff.
(4) displacement of fell W1 than littler in the pile knitting, is rotated so that fluffing motion 37 can be followed the high speed of pile fabric loom in the edge knitting.
(5) the fluffing motion has been developed and has been dropped into actual use for the pile in pile fabric loom braiding, and has obtained industrial reliability.Therefore, when the motion 37 of will fluffing during, fell W1 motion and wefting insertion have been stablized as fell moving member of the present invention.
(6) according to the first embodiment of the present invention, when being not when introducing weft yarn Y among a plurality of Weft insertion nozzle 2A-2H near one of them Weft insertion nozzle of fell W1, fell moving member 37 moves fell W1 towards the mobile direction of warp thread T (TP), displacement X2 is than ought be near the Weft insertion nozzle 2G of fell W1, and the displacement X1 when 2H introduces weft yarn Y is shorter.Therefore, fell W1 can only move essential minimum range and is used for stable wefting insertion.Therefore, reduced the driving load of fluffing motion 37 effectively.
Referring to Fig. 6, show the motion pattern of fell in according to a second embodiment of the present invention among Fig. 4, the difference of second embodiment and first embodiment is to have changed the edge Weaving pattern.In a second embodiment, similar reference number is illustrated in the similar part of using in the description of first embodiment, and will omit the detailed description to these parts.The edge Weaving pattern of selecting Weft insertion nozzle to be used for second embodiment is arranged to identical with the order of first embodiment.The edge Weaving pattern of second embodiment shows continuous wefting insertion pattern such as satin weave, before the weft yarn of being introduced by selected Weft insertion nozzle 2G is beaten up, according to this continuous wefting insertion pattern, carries out by the Weft insertion nozzle 2F that selects subsequently and comes wefting insertion.
When selecting Weft insertion nozzle 2G in the edge knitting, fluffing motion 37 is by coming from the instruction works of loom controller CR, so that fell W1 is moved forward distance X 1, takes this to promote the wefting insertion by Weft insertion nozzle 2G.Owing to do not beat up after wefting insertion, fell W1 is not back to stop position.Because fell W1 moves forward distance X 2 in by the wefting insertion of Weft insertion nozzle 2F, so fell W1 moves slightly backward.Be positioned to forward pitch in X2 at fell W1, Weft insertion nozzle 2F carries out wefting insertion.When finishing by the wefting insertion of nozzle 2F, fell W1 is back to stop position X3, at this place, is beaten up by special-shaped reed spare 5.Therefore, the present invention is suitable for weaving the edge Weaving pattern, wherein, is not beating up before the wefting insertion subsequently.In addition, all be back to first embodiment of stop position than fell W1 therein for each rotation of loom, second embodiment that shortens of the displacement of fell W1 more has superiority owing to correspondingly reduced fluffing campaign CD-ROM drive motor MT therein.
The present invention has been that background is described with above-mentioned first embodiment and second embodiment, but it is not limited to these embodiment.Obviously, the present invention can adopt the variety of way that goes out as model shown in hereinafter to be implemented.
Fell moving member of the present invention is not limited to the fluffing motion 37 of first embodiment, but it can be driving mechanism, and this driving mechanism can be operated in order to side by side drivingly through broadcasting motor MG, pile through broadcasting motor MP and coiling motor MW.Make coiling motor MW rotation predetermined angular and make ground warp broadcast motor MG and pile through broadcasting motor MP rotation predetermined angular along the direction of broadcasting of warp thread T (TP) by the coiling direction along knitted fabric W, fell W1 can move forward any desired distance.On the other hand, make coiling motor MW rotation predetermined angular and make ground warp broadcast motor MG and pile through broadcasting motor MP rotation predetermined angular along the coiling direction of warp thread T (TP) by the direction of broadcasting along knitted fabric W, fell W1 can be back to stop position backward.The present invention also can be applicable to do not have pile through broadcasting the loom of motor MP except that pile fabric loom.
