The specific embodiment
Below with reference to accompanying drawing, describe the preferred embodiments of the present invention in detail.
Fig. 1 represents as the stocking yarn cut-out of the straight-bar machines of one embodiment of the present invention and the brief configuration of holding device.In straight-bar machines 1, it is relative that the needle-bar 2 of front side F and rear side B clips tooth mouth 3.Arrangement pitches with knitting needle on each needle-bar 2 is formed with needle tray accordingly, and this needle tray is accommodated the knitting needle 4 of the slide displacement that carries out relative tooth mouth 3 advance and retreat.The slide displacement of each knitting needle 4 is optionally driven by the cam mechanism that is equipped on the cam carrier 5 that moves back and forth along needle-bar 2.Above tooth mouth 3, set up guide rail 6.Guide rail 6 supports yarn feeder 7 movably.Though the diagram of omission generally is provided with a plurality of guide rails 6, and a plurality of yarn feeders 7 can be set on each guide rail 6.Cam carrier 5 makes optionally interlock of arbitrary yarn feeder 7, supplies with stocking yarn 8 from the yarn feeder 7 of interlock to the pinhock of knitting needle 4 front ends that enter tooth mouth 3.Make up the supply of this stocking yarn 8 and the advance and retreat of knitting needle 4 and move making knit fabric 9.Knitted fabric 9 is from finishing the part of braiding, because of deadweight or pull device etc. move to the below of tooth mouth 3.
On straight-bar machines 1, be provided with controller 10, be used for according to the automatic making knit fabric 9 of weave data as control module.Controller 10 also carries out following control: with straight-bar machines 1 continuous weaving during as the knitted fabrics 9 such as clothes unit of Dan Pin, cut off between clothes and keep stocking yarn 8.Promptly, in order to cut off and to keep stocking yarn 8, be controlled to be with the retaining part 8b on one or more knitting needles 4 of leap part 8a between the needle-bars 2 before and after finishing in the braiding of knitted fabric 9 and the stocking yarn 8 of standby till the braiding that is used for next knitted fabric, use knitting needle 4 to form to cross over and a side needle-bar 2 sides.Be expressed as follows state in the accompanying drawings: the knitting needle 4 with the needle-bar 2 of front side F carries out the braiding of knitted fabric 9, takes off knitted fabric 9, after the knitting needle 4 of front side F forms hanging rings and then braiding retaining part 8b, hanging ring is moved to the knitting needle 4 of rear side B and forms cross over part 8a.By hanging ring being moved to the knitting needle 4 of rear side B, the knitted fabric 9 that takes off from the knitting needle 4 of front side F also hangs down into tooth mouth 3 from the knitting needle 4 of rear side B.
In these braid movements, the knitting needle 4 of formation leap part 8a and controller 10 form the unit as the leap part and work.Retaining part 8b uses a plurality of knitting needles 4 to form in Fig. 1.Even use 1 knitting needle 4, also can for example form part with same function by coiling stocking yarn 8.The knitting needle 4 of this formation retaining part 8b and controller 10 form the unit as retaining part and play a role.
To cross over part 8a in order cutting off, on cam carrier 5, to be equipped with cutter 11 as cutting unit.On cam carrier 5, also be equipped with the actuating mechanism 12 that makes cutter 11 relative tooth mouth 3 advance and retreat.Actuating mechanism 12 is by controller 10 controls, and controller 10 only is controlled to be actuating mechanism 12 cutting off when crossing over part 8a, makes cutter 11 enter tooth mouth 3, and cutter 11 is made a concession and standby from tooth mouth 3.
That is, clip the device that cuts off and keep stocking yarn 8 in the relative straight-bar machines 1 of tooth mouth 3, comprise as the controller 10 of control module with as the cutter 11 of cutting unit at front and back needle-bar 2.Controller 10, because with the braiding of end knitted fabric 9 and the stocking yarn 8 of standby till the braiding that is used for next knitted fabric, use the retaining part 8b on the knitting needle 4 of leap part 8a that a plurality of knitting needles 4 cross between the needle-bar 2 before and after being formed on and a side needle-bar 2 sides, thereby the special device that keeps stocking yarn 8 is not set, also can keep stocking yarn 8, thereby do not have the restriction of the quantity of yarn grasping devices such as yarn gripper, can keep a large amount of stocking yarns 8.Because retaining part 8b is located in the woven extent of knitted fabric 9 or near it, thereby the distance that the yarn feeding parts move also shortens, and can boost productivity.Cut off the stocking yarn of crossing over part 8a owing to cutter 11 moves along needle-bar 2, thereby in the braiding of knitted fabric 9, do not form obstruction.
In addition, preferably, the yarn grasping device by being located at needle-bar 2 ends etc. cut off and keep withdrawal of needle yarn, raveling cord, running-on hard waste etc.
Fig. 2 represents to carry on the cam carrier 5 structure of the part of cutter 11 and actuating mechanism 12.Actuating mechanism 12 comprises motor 15, driving mechanism 16 and guide 17.Motor 15 becomes drive source.Driving mechanism 16 changes the rotation of motor 15 into swing and cutter 11 is moved driving.Moving of guide 17 guiding cutters 11, the path relative tooth mouth advance and retreat of the front end that makes cutter 11 not interfere with knitting needle etc.By making cutter 11 enter tooth mouth 2, the blade 11a that is located at cutter 11 front ends is pressed on the leap part 8a cut-out that can cross over part 8a in the position of the leap part 8a of Fig. 1.
In addition, cutter 11 can also vibrate or form the dise knife of rotation in order to cut off reliably.And, also can form the scissors shape and cut off in the mode of cutting off.And suchlike various cutters just are not equipped on the cam carrier 5 yet, can also utilize guide rail 6 grades to move, and can move with cam carrier 5 interlocks in the same manner with yarn feeder 7.Like this, make as the cutter 11 of cutting unit and when mobile, can simplify the structure that is used to move with cam carrier 5.And, also can be provided with and make cutter 11 relative to mechanism that cam carrier 5 independently moves., under the situation that cam carrier 5 independently moves,, then also can cut off and cross over part 8a at cutter 11 if cutter 11 is moved in tooth mouth 3 as counteredge.
As mentioned above, owing to cut off to cross over the stocking yarn 8 of part 8a, and the end that keeps cut stocking yarn 8 with retaining part 8b, even thereby be not provided for the mechanism that keeps, the end that also can keep a large amount of stocking yarns 8.The braiding of the knitted fabric 9 of clothes unit finishes and when taking up one's knitting next clothes, continues and finish the knitted fabric 9 of braiding, can form easily and cross over part 8a and retaining part 8b.Under the situation of clothes internal cutting off and maintenance stocking yarn 8, also can utilize the interior knitting needle 4 of woven extent of clothes, or use adjacent knitting needle 4 outside woven extent forms leap part 8a and retaining part 8b.Knitting needle 4 in the woven extent can utilize not hold-in winding and vacant knitting needle 4.And, even the knitting needle of hold-in winding 4 if coil temporarily is transferred to other knitting needles 4 and vacant, also can utilize.Since can the inside of the knitted fabric 9 that weaves or near carry out the cut-out and the maintenance of stocking yarn 8, thereby the distance that yarn feeding parts such as yarn feeder 7 are moved also reduces, thereby can avoid the reduction of production efficiency.
Fig. 3 schematic representation forms an example of the yarn treatment of leap part 8a shown in Figure 1 and retaining part 8b.In the needle-bar 2 of front and back, the front side is expressed as F, rear side is expressed as B.Fig. 3 A for example represents to make cam carrier to move from right to left and weaves the state of the final row of knitted fabric shown in Figure 19.Then, in Fig. 3 B, do not supply with stocking yarn 8 and cam carrier is moved, take off the coil of final row.Usually, owing on cam carrier, be equipped with the cam mechanism of a plurality of systems, can move by 1 time, with respect to the knitting needle action of repeatedly advancing and retreat, thereby can carry out the braiding of Fig. 3 A by the cam mechanism system of going ahead of the rest, the cam mechanism system of going by the back carries out taking off of Fig. 3 B.In next Fig. 3 C, cam carrier is moved from left to right, on the knitting needle of the needle-bar of front side F, carry out hanging ring.The part of knitting needle is not carried out hanging ring, and separates the interval of hanging ring.That is, arrange at the needle-bar of front side F under the situation of knitting needle of a, b, c, d, e, f, g, h, for example only on a, b, d, f, h, carry out hanging ring, and do not carry out hanging ring at the knitting needle of c, e, g.Then in Fig. 3 D, cam carrier is moved from right to left, only on Fig. 3 C carries out knitting needle c, e, the g of hanging ring, do not carry out hanging ring.In the interval of knitting needle b, c, d, e, f, g, h, owing to utilize drawn needle to carry out hanging ring with respect to knitting needle b, d, f, h, in Fig. 3 D, carry out hanging ring, thereby can carry out the double rib braiding with respect to knitting needle c, the e, the g that do not carry out hanging ring at Fig. 3 C at Fig. 3 C.
Then in Fig. 3 E, cam carrier is moved from left to right, carry out the row braiding of lopping with respect to remaining knitting needle b, c, d, e, f, g, h behind the knitting needle a that removes left end.This braiding also can be carried out a plurality of rows.In Fig. 3 C, also the knitting needle b adjacent with the knitting needle a of front side F carried out hanging ring, but the hanging ring knocking over of knitting needle b and become old coil in Fig. 3 E.Then in Fig. 3 F, will transfer to the knitting needle of rear side B at the coil of the knitting needle a of Fig. 3 C hanging ring by barring-on.Cross over the knitting needle of rear side B and become and cross over part 8a, be hooked on knitting needle b, c, d, e, f, the g of front side F, the stocking yarn on the h becomes retaining part 8b from the stocking yarn between the old coil of the knitting needle b knocking over of front side F.Then in Fig. 3 G, be breaking at the leap part 8a that forms among Fig. 3 F with the cutter 11 of Fig. 1., discharge downwards from tooth mouth 3 through the part that the knitting needle of rear side B links to each other with the knitted fabric 9 of Fig. 1 from cut-off parts with knitted fabric 9.The stocking yarn 8 that links to each other with yarn feeder 7 can begin to carry out the braiding of next knitted fabric under retaining part 8b remains on state on knitting needle b, c, d, e, f, g, the h.Retaining part 8b can inweave in the defiber line part of withdrawal of needle before the next clothes of braiding.Even in same clothes, supplying with the braiding position of stocking yarn 8 under the situation that the row direction is separated from same yarn feeder 7, by similarly using knitting needle to keep, cut off, can prevent between the braiding position, to produce the transition yarn, can reduce the labour of yarn treatment.
That is, the braiding of retaining part 8b comprises the tertiary coil line braiding shown in second row braiding shown in first row braiding shown in Fig. 3 C, Fig. 3 D and Fig. 3 E and carries out.In braiding of first row and the braiding of second row, carry out interlock braiding based on hanging ring, in tertiary coil line braiding, use other knitting needles that carry out the interlock braiding except the knitting needle that in the braiding of first row, carries out hanging ring at first to be formed into the braiding of turn coil.Also can repeat repeatedly the row braiding identical with tertiary coil line braiding.Because crossing over part 8a is formed by the stocking yarn between hanging ring that weaves with first row and the old coil adjacent with this hanging ring, retaining part by with cross over interlock that part is connected partly with form with its continuous turn coil that becomes, thereby can keep yarn ends and it is not untied.
In addition, though in Fig. 3 B, take off knitted fabric,, between the needle-bar of front and back, produces the leap part in the next meeting of the state of Fig. 3 F from the knitting needle of the front side F that crosses over part 8a left side, thereby can cut off this part if do not take off knitted fabric.Wherein preferably, cut off forming leap part 8a, and the side of close retaining part 8b.If in Fig. 3 B etc., take off knitted fabric, then can not in Fig. 3 G, cut off stocking yarn as the left side of crossing over part 8a.
And, also can beyond Fig. 3 B, take off knitted fabric.For example, also the temporary transient barring-on of coil that forms at Fig. 3 A knitting needle to rear side B can be carried out the later braiding of Fig. 3 C, behind Fig. 3 C, Fig. 3 D or Fig. 3 E, promptly before Fig. 3 F, take off knitted fabric and get final product.And, also can be behind Fig. 3 A, carry out the later braiding of Fig. 3 C with the knitting needle of rear side B.In this case, as long as before Fig. 3 F, just can carry out taking off of knitted fabric at any time.
Fig. 4 A and Fig. 4 B represent the example as the yarn treatment of another embodiment of the present invention.In Fig. 4 A, different with the barring-on of Fig. 3 F, the coil of knitting needle a residues on the F of front side, the one-tenth turn coil of knitting needle b, c, d, e, f, g, h is moved on to rear side B and form to cross over part 8a and retaining part 8b.Can shown in Fig. 4 B, cut off the leap part 8a that forms like this by cutter.
Like this, in the straight-bar machines with the warp thread insertion mechanism that comprises the parts that are known as away the shuttle bar, cut-out and maintenance are under the situation of the warp thread of warp thread insertion mechanism supply, particularly preferably in rear side B formation retaining part 8b.Insert the straight-bar machines of mechanism about having warp thread, be disclosed in No. 3452639 communique of Japan Patent etc.And the applicant's manufacturing and sell goods name are called the straight-bar machines that warp thread inserts mechanism that has of SPL122CS or LAPIS.The specification of these straight-bar machines is as follows: have needle-bar in front and back, warp thread inserts the top that mechanism is arranged at the back needle-bar, and only the knitting needle of needle-bar is supplied with warp thread forward.
