Fig. 8 is about holding yarn to insert the order that refers to bag, and representing the front view of the action of the end-yarn insertion device main body 24 in each operation.Fig. 9 is the cutaway view of the action of expression end-yarn insertion device main body 24.Figure 10 be when representing to weave briefly cam carrier 13, cut off the figure of the position relation between grasping device 21 and the end-yarn insertion device main body 24.Only represent stop-motion body 32, end yarn hook 33 and end yarn presser feet 34 at Fig. 8, Fig. 9.Below, illustrate in gloves knitting machine 2, at end-yarn insertion device 1 clamping transition yarn, will cut off the transition yarn and the end yarn that obtains inserts the action before referring in the bag.

What respectively refer to bag is knitting when finishing at every turn, is caught from the transition yarn that refers to that root portion is extended to yarn feeder 19 by the hook that cuts off grasping device 21, and cuts off and control the transition yarn.Cut off the transition yarn like this and carry out the withdrawal of needle that the next one refers to bag.The end that is cut off the transition yarn of grasping device 21 cut-outs promptly holds yarn by end-yarn insertion device 1 clamping.End-yarn insertion device 1, the inside of the end yarn of clamping being inserted the finger bag that then weaves.Refer to that at each the end yarn that produces in the braiding of bag can not stretch out to the gloves outside thus, thereby need not in post processing, will hold yarn to insert gloves inside.

Below, illustrate when one of braiding refers to that the bag and the next one refer to bag, the end yarn is inserted a next situation that refers to that bag is interior.Gloves knitting machine 2 by supplying with stocking yarns from yarn feeder 19 to tooth mouth 8, drives cam carrier 13, makes a plurality of knitting needles 7 advance and retreat, thus with one refer to bag 300 from finger tip part 300a braiding to referring to root portion 300b.At this moment, end-yarn insertion device main body 24 is not positioned at and can produces dysgenic left and right directions position to braiding.And make capture unit 67 and pressing part 73 make a concession on position standby respectively (Fig. 8 a, Fig. 9 are a) at each.Making a concession on the position, the hook bend 62 of end yarn hook 33 and application point portion 152 are relative and the state of maintenance application point portion 152 inward direction C2 displacements with respect to the inner surface 201 of matrix 31, becomes the state of the 151 inward direction C1 of force portion sinking.

When weaving the finger root portion 300b of a finger bag 300, make yarn feeder 19 than the next one that takes up one's knitting refer to bag 301 interval P further left direction A1 move that (Figure 10 a), grasping device 21 is cut off in starting under this state, makes cut-out grasping device 21 catch the transition yarn 302 (Figure 10 b) that extends to yarn feeder 19 from the finger root portion 300b of a finger bag.And starting is cut off grasping device 21 and is cut off and control transition yarn (Figure 10 c).During cut-out,, thereby refer to that by cutting off 302, one on transition yarn the end yarn 106 of bag 300 sides enters one and refers in the bag 300 because the transition yarn is configured in a top that refers to bag 300.Then, make end-yarn insertion device main body 24 move (Figure 10 c) towards the end yarn clip position that is used for the clamping stocking yarn of the direction A1 that keeps left than interval P by first CD-ROM drive motor 81.

End-yarn insertion device main body 24 by second CD-ROM drive motor 85, moves and jack-up roller 65b upward the position rod member 89 when the mobile end of end yarn clip position upward.Thus, make end yarn hook 33 angular displacement take place, swing displacement (Fig. 8 b, Fig. 9 b) towards catching position thereby make end yarn hook 33 make a concession the position from hook around angular displacement axis L1.When end yarn hook 33 is done the swing displacement, apply from the spring force of presser feet yielding position to end yarn presser feet 34 by spring members 36, hold yarn presser feet 34 to make a concession the position from presser feet and swing displacement thus to clip position with the swing displacement interlock of end yarn hook 33 towards clip position.Swing when at first, end yarn hook 33 slides in the application point portion 152 of stop-motion body 32.Then, end yarn hook 33 and end yarn presser feet 34 depart from from application point portion 152.Hold the relative status between yarn hook 33 and end yarn presser feet 34 and the application point portion 152 to be disengaged thus, stop-motion body 32 reverts to nature by restoring force thus.

Continue to make 85 actions of second CD-ROM drive motor, when holding

yarn hook

33 and 34 sustained oscillations of end yarn presser feet thus, end yarn hook 33 is arrived catching position by standing part 170 fastenings of the second guiding parts 35b.Hold yarn presser feet 34 this moment, bear portion 75 by stop and prevent to arrive clip position with stopping part 204 butts of application point portion 152, thereby at position of readiness standby (Fig. 8 c, Fig. 9 c).Hold yarn hook 33 this moment, applied by spring members 36 under the state of the active force of clip position, in the position of readiness standby.Like this, capture unit 67 and pressing part 73 B along the vertical direction separate, thereby are in the state that can catch by the stocking yarn of 67 pairs of yarn feedings of capture unit.During making that capture unit 67 separates with pressing part 73, make and cut off grasping device 21 and move (Figure 10 d) to A1 to the left of capture unit 67.

Under this state, with respect to end-yarn insertion device main body 24, cam carrier 13 is moved to right A2 with yarn feeder 19, catch by capture unit 67 under the state of the stocking yarn of supplying with from yarn feeder 19, refer to finger tip part in the bag by a plurality of knitting needles 7 next one that takes up one's knitting.。Cam carrier 13, when direction A passed through to the left and right with end-yarn insertion device main body 24, the abutting part 200 that is formed on the cam carrier 13 contacted with the force portion 151 of stop-motion body 32, and makes force portion 151 with respect to matrix 31 outward direction C1 displacements.Thus, stop-motion body 32 carries out angular displacement around fulcrum 150, the 152 inward direction C2 displacements (Fig. 9 d) of application point portion.

At this moment, stopping part 204 bears the 75 inward direction C2 of portion from stop and breaks away from, thereby removes the fastening of stopping part 204 opposite end yarn presser feets 34.Thus, end yarn presser feet 34, the spring force that produces because of spring members 36, towards clip position around angular displacement axis L1 swing displacement (Fig. 8 d), and the end yarn 105 (Fig. 8 e, Figure 10 e) of catching by capture unit 67 by capture unit 67 and pressing part 73 clampings when arriving clip position.And when clip position moved, it is relative with application point portion 152 that portion 75 is born in stop from position of readiness for end yarn presser feet 34, thereby prevention stop-motion body 32 returns to nature (Fig. 9 e).Catching by capture unit 67 under the state of the stocking yarn of yarn feeder 19 yarn feedings thus, supplying with stocking yarn and with a plurality of knitting needles 7 finger tip that the next one refers to bag partly (Figure 10 f) that takes up one's knitting to interval P.

Then under the state of bare terminal end yarn 105, driving is cut off grasping device 21 and is discharged end yarn 105 from cutting off grasping device.And by second CD-ROM drive motor 85, rod member 89 is moved the position downwards, make end yarn hook 33 make a concession the position towards hook thus and do the swing displacement from catching position.End yarn presser feet 34 is made a concession the position from clip position towards presser feet and is done swing displacement (Fig. 8 f, Fig. 9 f) with the swing displacement interlock of end yarn hook 33.At this moment, lift pressing part 73 upward and under the state of bare terminal end yarn 105, end yarn hook 33 and end yarn presser feet 34 reach respectively makes a concession the position in capture unit 67.End yarn hook 33 and end yarn presser feet 34 are laying respectively under the state of making a concession the position, bare terminal end yarn 105 and make end yarn 105 make a concession (Fig. 8 g, Fig. 9 g, Figure 10 g) from a plurality of knitting needles 7.Can prevent from thus to twine at the next process middle-end yarn 105 of bag that refers to of braiding.And make a concession when making a concession the position, because end yarn hook 33 is relative with application point portion 152, thereby becomes application point portion 152 from nature inward direction C2 displacement, force portion 151 is from the state of nature outward direction C1 displacement.

The finger tip that the next one is referred to bag partly weaves a plurality of rows, yarn feeder 19 to the next one refer to the bag the left side move the back (Figure 10 h), first and second CD-

ROM drive motor

81,85 is driven, capture unit 67 and pressing part 73 make end yarn hook 33 and end yarn presser feet 34 move (Figure 10 i) to describe the mode of outstanding parabolic path downwards.Hold thus yarn hook 33 and end yarn presser feet 34 along the vertical direction B separates, make end yarn 105 break away from and the end yarn 105 insertion next ones of clamping are referred in the bag from end yarn hook 33.Then, make end yarn hook 33 and end yarn presser feet 34 make a concession the position respectively and make a concession, and make one to refer to that bag 300 moves to the position of crossing right A2 side to each.Also continue behind the insertion end yarn 105 from yarn feeder 19 yarn feedings, can continue the braiding next one by a plurality of knitting needles 7 and refer to bag 301.Thus, when braiding respectively refers to bag successively, cut off and control the transition yarn, and should cut end yarn insertion respectively refer in the bag by end-yarn insertion device main body 24.

In the above description, shown in Figure 10 e, Figure 10 f, refer at the braiding next one before the finger tip part of bag, by end-yarn insertion device main body 24 bare terminal end yarns 105, but as other end yarn method of clamping, also can be after the braiding next one refers to finger tip a plurality of rows partly of bag, by end-yarn insertion device main body 24 bare terminal end yarns 105.

Figure 11 is the figure that schematically shows the end yarn holding action of end-yarn insertion device main body 24.End-yarn insertion device main body 24 is being caught the state of preparing end, promptly under the state of Figure 10 d, is formed with gap X between the pressing part 73 of capture unit 67 of holding yarn hook 33 and end yarn presser feet 34.And with respect to end-yarn insertion device main body 24, the abutting part 200 that cuts off hook portion, yarn feeder 19 and the cam carrier 13 of grasping device 21 is configured in left, and upward (Figure 11 a) to A1.

From this state, yarn feeder 19 moves to the right A2 of end-yarn insertion device main body 24, thus, crosses over the end yarn 105 that yarn feeders 19 extend from cutting off grasping device 21, between the capture unit 67 by end yarn hook 33 and the pressing part 73 of end yarn presser feet 34.And, cam carrier 13 moves to the right A2 of end-yarn insertion device main body 24, thus, the abutting part 200 of cam carrier 13 contacts with force portion 151 and removes the fastening of end yarn presser feet 34, the end yarn presser feet 34 clampings end yarn 105 (Figure 11 b, Figure 10 e) that portion 67 catches that is captured.Under this state, be positioned at the knitting needle 7 of the right A2 of end-yarn insertion device main body 24, catch the yarn that between end-yarn insertion device main body 24 and yarn feeder 19, extends and begin to carry out withdrawal of needle.

In the present embodiment, end yarn hook 33 has and contacts with the yarn of catching and along the capture surface 190 of left and right directions A extension.End yarn presser feet 34 has under the state of and clamping yarn moving with end yarn hook 33 associations at clip position clamping face 191 and the pressing down section 192 relative with the capture surface 190 of holding yarn hook 33.Under the state of bare terminal end yarn 105, the yarn feeder 19 side bendings of pressing down section 192 from clamping face 191 are extended towards knitting needle 7 from clamping face 191, with capture unit 67 adjacency configurations.

From the yarn feeder side part 105a of capture surface 190 to the extension of yarn feeder 19 sides, by with the lower surface butt of pressing down section 192, it is crooked downwards to compare the part that contacts with capture surface 190, and extends towards yarn feeder 19 by the position of below from the capture surface 190 than end yarn hook 33.Like this, end yarn presser feet 34, presses down the end 105b near capture surface among the yarn feeder side part 105a of end yarn 105 under the state of bare terminal end yarn 105 moving with end yarn hook 33 associations to the below of capture surface 190.Thus after by end-yarn insertion device 1 bare terminal end yarn 105, the braiding next one refers under the finger tip situation partly of bag 310, can be reduced in first knitting needle 7 using in the braiding that the next one refers to bag and care for the position that hooks of end yarn, the hook yarn that can prevent knitting needle 7 is bad and stably carry out the hook yarn of knitting needle 7.Even thereby the little plane No. knitting machine that diminishes of the shape of hook, perhaps carry out plating-knitted knitting machine, can both prevent that the hook yarn is bad.And the hook yarn when carrying out withdrawal of needle by making by knitting needle 7 becomes easily, and the adjustment that can enlarge the position alignment of yarn feeder 19 is allowed width and made the position adjustment of yarn feeder 19 become simple.Even and be set at not at the catching position that will hold yarn hook 33 under the state of the lower position of interfering with miscellaneous part, also can pass through end 105b with the close capture surface of the yarn feeder side part 105a that holds 34 times pressure side yarns 105 of yarn presser feet, and then the hook yarn position that reduces knitting needle 7.Particularly, at end yarn hook 33 with carry out first knitting needle 7 of withdrawal of needle that the next one refers to bag 301 along under the situation approaching on the left and right directions, end 34 times pressure side yarns of yarn presser feet and make the effect of hook yarn stabilisation bigger.

As mentioned above,, owing to do not make end yarn hook 33 displacements that are positioned at catching position, and make end yarn presser feet 34 displacements and the bare terminal end yarn according to the end-yarn insertion device 1 of present embodiment, thus the change of the yarn tension that produces can suppress the bare terminal end yarn time.Thus before remove cutting off the controlling of grasping device 21 opposite end yarns, can prevent the lax of yarn tension, and can prevent the damage of controlling of not-go-end yarn by end-yarn insertion device 1 bare terminal end yarn in advance, thus bare terminal end yarn reliably.The end yarn can be inserted knitted fabric inboards such as gloves reliably thus.

And only by make cam carrier 13 with respect to end-yarn insertion device main body 24 to the left and right direction A pass through, just can remove the fastening of stopping part 204 opposite end yarn presser feets 34, thus can bare terminal end yarn 105.Making the cam carrier 13 direction A action of moving to the left and right like this is to be used for weaving one to refer to the next action that refers to a succession of action of bag of braiding after the bag.Thereby do not need to change the action degree of control part of each drive division of control knitting machine and the clamping that can easily hold yarn.

And because according to the driving sequential of the mobile decision end-yarn insertion device of cam carrier 13, thereby needn't adjust the mobile sequential of cam carrier 13, the driving sequential of end-yarn insertion device separately, thus can prevent to produce the deviation of clamping sequential.And, for realize between cam carrier 13 and the end-yarn insertion device main body 24 synchronously, needn't set the resolution ratio that the left and right directions of cam carrier 13 moves accurately, can simplified structure.And, needn't reset the driving mechanism that is used to make stop-motion body 32 drivings, can reduce number of components and simplified structure.

And by each guiding

parts

35a, 35b, anti-not-go-end yarn hook 33 separates from board 41 with end yarn presser feet 34.Can prevent that thus the thickness direction along matrix 31 vibrates when

end yarn hook

33 and 34 swings of end yarn presser feet.Can with the 152 inward direction C2 of the application point portion pushing of stop-motion body 32, thereby make stop-motion body 32 do relative displacement by end yarn hook 33 and end yarn presser feet 34 thus with respect to matrix 31.And because stop-motion body 32 and spring force applying unit 153 form one, thereby can and then reduce number of components.

In the present embodiment, on cam carrier 13, be provided with the abutting part 200 that contacts with the force portion 151 of stop-motion body 32, but, also can use other driving mechanisms to come stop-motion body 32 is applied external force if can apply the driving mechanism of external force to stop-motion body 32.For example as known devices, can replace cam carrier 13 and abutting part 200 is set at yarn feeder 19.And shown in Fig. 9 d, because abutting part 200 forms the elongate in shape of extending along left and right directions A, thereby mistake is removed in the fastening that can prevent not-go-end yarn presser feet 34.And also can by cam carrier 13 from right A2 left direction A1 cross end-yarn insertion device main body 24 and hold the fastening of yarn presser feet 34 to remove.And because the edge of the ledge of the force portion 151 of stop-motion body 32 forms glossily, thereby the impact can reduce

abutting part

200 and 151 conflicts of force portion the time.

And, being positioned under the state of position of readiness at end yarn hook 33 and end yarn presser feet 34, the ledge of the force portion 151 of stop-motion body 32 sinks into matrix 31, thus, can prevent force portion 151 and abutting part 200 butt unexpectedly.And because the edge of the application point portion 152 of stop-motion body 32 forms glossily, thereby the impact when contacting with application point portion 152 can reduce end yarn hook 33 and hold yarn presser feet 34 to return position of readiness the time.

And in the present embodiment, be illustrated, but also can be by end yarn that refers to the bag side of end-yarn insertion device main body 24 clampings, and will above-mentioned end yarn insert under the situation about referring in the bag and use holding yarn to insert the next method of bag that refers to.And as shown in the above-mentioned patent documentation 1, end-yarn insertion device main body 24 also can opposite end yarn hook and the swing control of hook presser feet before and after carrying out, and makes it describe to avoid the track of sinker.And stop-motion body 32 and spring force applying unit 153 also can separately form.And in the present embodiment, as an example of straight-bar machines and gloves knitting machine 2 has been described, but being not limited to the gloves knitting machine, is that straight-bar machines is just passable.It for example can also be the socks straight-bar machines of braiding the five fingers socks.
