When with selection piece 15 during at A position needle selection, presser feet 15a is subjected to the effect of tuck eedle presser 41a, and the presser feet 14b of needle jack 14 is sunk to needle tray.But this interval tangles the interval of the top 30a of back row side for presser feet 15a, even presser feet 15a sinks to needle tray, presser feet 14b also by with as track 14bH﹠amp; Identical path, H position shown in the A.That is, no matter pin main body 10 still in A position, all carries out identical braid movement in the H position.
Needle selection when the arbitrary position by A position and H position, needle jack 14 presser feet 14b via embossing triangle 30 when the tooth oral-lateral rises, pusher jack matrix 12 also projects upwards.The second presser feet 12b of pusher jack matrix 12 by pusher jack along separate routes triangle 39b and pusher jack make progress between the triangle 37, and rise along the make progress outer circumferential tooth oral-lateral in triangle 37 left sides of pusher jack.The second presser feet 12b descends a little in the lower edge central authorities of pusher jack guiding triangle 35, and across the make progress inclined plane on triangle 37 right sides of pusher jack, arrives the pusher jack shunt portion of triangle 39a along separate routes.
In shunt portion, the presser feet 15a of the selection piece 15 of H position is not subjected to pushing of eedle presser.The first presser feet 12a of pusher jack matrix 12 is not subjected to pushing of lopping eedle presser 23a yet, therefore the second presser feet 12b is directed along the periphery of the shunt portion of pusher jack shunt triangle 39a, guiding pusher jack guiding triangle 36a and pusher jack keep the path between the triangle 38a, pusher jack 11 keeps tongue piece 13a is gone out to the state of tooth mouth before the track 12bH shown in the solid line, goes out under the state of tooth mouth to keep old wire loop before tongue piece 13a.The old wire loop that remains in tongue piece 13a is gone out pinhock 10a to the tooth mouth before the needle-bar of subtend follow-up braiding circuit moves by side to, and break away from, can increase circle from tongue piece 13a.
As the presser feet 15a of selection piece 15 during at A position needle selection, presser feet 15a is pushed by tuck eedle presser 41a, consequently, along the second presser feet 12b of the path 12b A guide lead sheet matrix 12 shown in the dotted line, and corresponding with the braid movement of lopping, retreat from the tooth mouth.When pusher jack matrix 12 retreated from the tooth mouth, the old wire loop that remains on the tongue piece 13a broke away from from the top of tongue piece 13a, carries out knocking over.The first presser feet 12a of pusher jack matrix 12 is corresponding with track 12bH, the 12bA of the second presser feet 12b respectively, moves along track 12aH, 12aA.
As shown in Figure 2, when only making the tuck eedle presser 41a effect of back row side in the A position, do not do the time spent, can switch and weave and increase circle and lopping eedle presser 23a is set at.That is, can switch the braid movement of lopping to each knitting needle by the needle selection of A position, the needle selection by the H position can switch the action that increases circle.In addition, when the second presser feet 12b with pusher jack matrix 12 switches to the path that increases circle, along pusher jack along separate routes the periphery of triangle 39a, 39b upside be directed, therefore in pin main body 10 when the tooth mouth retreats, also can prevent because of retreating that rash action causes.
Fig. 3 represents not carry out increasing the action of enclosing and can switch lopping and tuck.In the A position, two tuck eedle presser 41a, 41b both sides are acted on.Also make lopping eedle presser 23a effect.With the track 14bH of the presser feet 14b of the needle jack 14 of selection piece 15 when the needle selection of H position the top 30b of side in advance, by the path of mountain type along embossing triangle 30.Track 14bA at the presser feet 14b of A position crosses top 30b, keeps the height of shoulder.Presser feet 14b crosses the top 30a of back row side, the track 14bH﹠amp that descends along the inclination of stitch triangle 32a; A is identical.
According to having or not pushing of tuck eedle presser 41b,, the path of the presser feet 14b of needle jack 14 is switched to track 14bH and track 14bA at the top 30b of side in advance of embossing triangle 30.Corresponding therewith, also the path with the second presser feet 12b of pusher jack matrix 12 switches to track 12bH and track 12bA.On the track 12bA shown in the dotted line, whether pin main body 10 or not do not go out to the tooth mouth before removing is limited to the coil loop of pinhock 10a, so pusher jack 11 went out before also to the mode of tooth mouth and is not driven.On the track 12aH shown in the solid line, pusher jack 11 also go out before in the mode of removing coil loop to the tooth mouth along with pinhock 10a and before go out to the tooth mouth, after this, shunt portion at pusher jack shunt triangle 39a, push the first presser feet 12a by lopping eedle presser 23a, pusher jack 11 descends according to the track 12bA that retreats from the tooth mouth.
That is,, then carry out the braid movement of lopping,, then carry out the braid movement of tuck if needle selection is the A position if needle selection is the H position.Owing to carry out the braid movement of flotation line in the B position, so, can switch lopping, tuck, three basic braid movements of flotation line by making lopping eedle presser 23a effect.As long as switch three braid movements,, also can use fixed eedle presser as tuck eedle presser 41a, 41b.But, increase circle in order also to switch, need make movable with respect to the eedle presser of tuck to the major general.In addition, when not with movable tuck eedle presser 41a, 41b and movable lopping eedle presser 23a, when 23b uses together, as shown in Figure 2, can switch by lopping and to increase circle, as shown in Figure 3, not increase circle, can not switch lopping and tuck.
Fig. 4 represents the formation as the major part of the horizontal volume machine 51 of other form of enforcement of the present invention.In Fig. 4, use identical reference marks with the part that Fig. 1 is corresponding, the repetitive description thereof will be omitted sometimes.
Horizontal volume machine 51 also uses the compound needle 2 identical with horizontal volume machine 1.In horizontal volume machine 51, pin main body operation is different with horizontal volume machine 1 with triangle 50 and pressing board 52, also can carry out the different switching of density.Therefore, on stitch triangle 60a, the 60b of the cam system 53 that is loaded into balladeur train, the different portions 62 with the density of maximum limit height of the base portion 61 of half height use movable parts.Shown in the stitch triangle 60b in the left side of Fig. 4, when the lower end at base portion 61 was provided with density difference portion 62, the different amounts of density were 0.When the different amounts of density were 0, stitch triangle 32a, the 32b with Fig. 1 is the same basically, and be only corresponding with a kind of density value, carries out leaving behind of pin main body 10.As shown in the stitch triangle 60a on Fig. 4 right side, when with density difference portion 62 when the lower end of base portion 61 is slided, can carry out the different braiding of density.But the A position with respect to the presser feet 15a of selection piece 15 increases movable density different eedle presser 63a, 63b in the both sides of tuck eedle presser 41a, 41b.
The main action of the horizontal volume machine 51 of Fig. 4 when Fig. 5 and Fig. 6 represent the balladeur train left lateral.But if set density different eedle presser 63a, 63b for not acting on, setting stitch triangle 60a, 60b is that the different amount of density is 0, and then the horizontal volume machine 1 with Fig. 1 is the same, can comprise the action that increases circle.
Fig. 5 is illustrated in the size that can distinguish density in the lopping braiding, the action of switching thick line circle lopping and standard coil lopping.To the go ahead of the rest different eedle presser 63b of the density of side and tuck eedle presser 41b of the eedle presser of H position is set at and do not act on, and the tuck eedle presser 41a and the different eedle presser 63a of density of back row side is set at effect.Lopping eedle presser 23a is set at effect.
The second presser feet 12b of pusher jack matrix 12 is as track 12aH﹠amp; Shown in the A like that, make selection piece 15 no matter in the H position, still all pass through identical track in the A position.That is, the tongue piece 13a of pusher jack 11 is in case preceding going out behind the tooth mouth, retreat from the tooth mouth.Act on the along separate routes position of the shunt portion of triangle 39a of pusher jack at the second presser feet 12b, only carry out pushing in the H position the first presser feet 12a of lopping eedle presser 23a.Also the presser feet 15a enforcement of the selection piece 15 of the tuck eedle presser 41a of row side is afterwards pushed in the A position.In arbitrary position, when the second presser feet 12b acted on the shunt portion of pusher jack shunt triangle 39a, the shunt portion of crossing half height was directed to the path that pusher jack 11 is descended.
Change the action of the amount of the leaving behind switching density of pin main body 10 by the different eedle presser 63a of density in the effect of A position.In the H position, shown in the track 14bH shown in solid line, the presser feet 14b of needle jack 14 drops to the lower end along the periphery of the base portion 61 of stitch triangle 60a.In the A position, shown in the track 14bA shown in dotted line, presser feet 14b only drops to the lower end of the density difference portion 62 of maximum limit height, and the base portion 61 of half height is crossed thus.
Fig. 6 represents to switch the action of the lopping tuck different with density.The eedle presser 63b that the density of the side of will going ahead of the rest in the A position is different is set at and does not act on, with tuck eedle presser 41b, the tuck eedle presser 41a of back row side of side and the different eedle presser 63a of density of back row side are set at effect in advance.Lopping eedle presser 23a also is set at effect.In the H position, pin main body 10 and pusher jack 11 carry out the braid movement corresponding with lopping according to track 14bH, the 12bH shown in the solid line.In the A position, pin main body 10 is corresponding with the track 14bA shown in the dotted line, crosses the top 30b of side in advance of embossing triangle 30, carries out the action of tuck, and stitch triangle 60a crosses base portion 61, carries out the different action of density.That is, carry out the different braid movement of tuck density in the A position.Track 12bH shown in solid line is such, and pusher jack 11 goes out before in lopping after the tooth mouth to descend, and track 12bA shown in dotted line is such, does not before go out to the tooth mouth in tuck.
The cam system 3 of Fig. 1 and the cam system 53 of Fig. 4 do not comprise the triangle of relevant barring-on.In the formation of cam system 3,53, as the last stage that increases circle,, old wire loop can be remained on the tooth mouth by the tongue piece 13a of pusher jack 11, still, can not accept old wire loop in the needle-bar side of subtend.In the present embodiment, follow-up cam system possesses the triangle that barring-on is used, and can realize increasing the action of circle or barring-on.Identical with Fig. 5 of patent documentation 2 etc., if cam system 3,53 also increases the triangle of relevant barring-on, then can use the trigonometric sum that increases circle to carry out the triangle of barring-on simultaneously.
For example, on path with respect to the H position of the presser feet 15a of selection piece 15, if with pusher jack along separate routes triangle 39a, the corresponding phase place of 39b eedle presser is set, then also lopping eedle presser portion 23 can be set.But eedle presser concentrates on pressing board 22,52 mostly, can dispose closely.The lopping eedle presser 23a, the 23b that were arranged in 22,52 minutes owing to the pressing board that makes and act on the presser feet 15a of selection piece 15 act on the first presser feet 12a of pusher jack matrix 12, so can simplify the relevant formation that increases the pressing board 22,52 of circle.In addition, because lopping eedle presser 23a, 23b directly act on the first presser feet 12a of pusher jack matrix 12, so, the second presser feet 12b of b pusher jack matrix 12 can be sunk to needle tray in that needle jack 14 is influenced under the little state.
