Abstract
A weft knitting machine, comprising a movable yarn guide capable of preventing a knitting fabric from being damaged by the catch of a yarn. Since the advancement of the movable yarn guide to a tip part (5) is reduced near a position where the yarn is fed from a yarn feed port (10a), the yarn can be fed smoothly and the catch of the yarn by sliders (7b, 8b) can be prevented from occurring. Since the advancement of the movable yarn guide (1) to the tip part (5) is increased near a position where the yarn is received by hooks (7c, 8c), the yarn can be securely caught by the hooks (7c, 8c). When needle bodies (7a, 8a) are pulled into needle beds (3, 4) and stitch loops are formed by the hooks (7c, 8c) and the tip edge (6b) of a sinker (6), a guide part (1a) at the tip of the movable yarn guide is driven so as to be retreated from the tip part (5) to a position where the sinker (6) forms a sinker loop, and therefore the lower end of the guide part (1a) capable of securely forming the sinker loop at the angle determination position of the sinker (6) is extended to cover a tongue (8d) so as to prevent the yarn from being caught.
Description
Technical field
The present invention relates to a kind of straight-bar machines with movable yarn guide, the relative together tooth mouth advance and retreat with knitting needle of this movable yarn guide are with the pinhock guiding of stocking yarn to knitting needle.
Background technology
In the past, in straight-bar machines, made knitting needle from clipping the relative tooth mouth of the relative needle-bar of tooth mouth advance and retreat, from the pinhock supply stocking yarn of the last direction knitting needle of tooth mouth and carry out the braiding of knitted fabric.Supply at the stocking yarn at tooth mouth place enters at the pinhock that makes knitting needle under the state of tooth mouth depths, carries out near the central portion of tooth mouth from the feed of yarn feeding parts such as thread-carrier.Enter to the knitting needle of tooth mouth, when drawing in needle-bar stocking yarn is caught in pinhock retreating from the tooth mouth.Knitting needle is drawn in stocking yarn needle-bar and is formed coil along the needle tray that is located on the needle-bar.Coil comprise that the pinhock of knitting needle is drawn in needle-bar with stocking yarn and the needle loop that forms and between adjacent knitting needle by the sinker loop that forms in the face of tooth mouth sinker.The size of formed coil is by the loop density decision of the pinhock of knitting needle being drawn in needle-bar.When determining this loop density, the position of facing the sinker of tooth mouth becomes benchmark.
For example No. 3333304 communique of Japan Patent is open, for stocking yarn is guided to pinhock reliably, uses front end can cross the front end of sinker and enters near the central authorities of tooth mouth movable yarn guide member.Movable yarn guide member retreats from the tooth mouth near the position of supplying with stocking yarn from the feed of yarn feeding parts, interferes with feed avoiding.During from feed supply stocking yarn, movable yarn guide member enters the tooth mouth and stocking yarn is guided to pinhock.When forming coil, movable yarn guide member also keeps entering the state of tooth mouth.Even being shaped as of the front end downside of movable yarn guide member enters the path formation obstacle that the tooth mouth also can not drawn in stocking yarn to pinhock, promptly can not interfere this path.In No. 3333304 communique of Japan Patent, sinker also is to be the movable sinker of swinging displacement at center with near the locational fulcrum front end that is located at needle-bar, swings the fore-end of displacement and also brings into play the effect that knitted fabric is pressed down to tooth mouth below.
And knitting needle adopts and to be divided into pin main body and pusher jack and to open and close the compound needle that is located at the pinhock on the pin body front end with pusher jack.In compound needle, drive pin main body and pusher jack, the pinhock of pin main body enter the tooth mouth during, pusher jack rests near the needle-bar front end.Wherein, when the pin main body entered to the knitting position of tooth mouth, the coil that has formed remained on the pusher jack as old coil.New coil cared on pinhock and when pinhock drawn in needle-bar, close pinhock with pusher jack and make old coil knocking over and carry out the braiding of knitted fabric.Therefore, when the pin main body entered the tooth mouth, pusher jack also entered near the tooth mouth, need make the easy separating tooth mouth of old coil of knocking over.But,, then might do not caught by pinhock if the former stocking yarn of being caught by pinhock is cared on pusher jack.Movable yarn guides such as movable yarn guide member, also performance prevents the effect that stocking yarn is cared for to pusher jack.
In straight-bar machines, making needle-bar clip the relative reason of tooth mouth is, the knitting needle of the enough arbitrary needle-bars of energy is the front coil and the purl loop of woven stitch respectively, use the knitting needle braiding of both sides' needle-bar to be known as the tissue of rib stitch (go system Knitting body or リ Block Knitting body), braiding comprises the multiple texture pattern of barring-on etc.In recent years, also use both sides needle-bar knitted cylindrical fabric.
And for example Japanese special fair 7-96740 communique is disclosed, for multiple texture pattern knitted cylindrical fabric, has also developed and will clip 2 sections up and down of the relative needle-bar settings of tooth mouth, uses the straight-bar machines of 4 needle-bars on the whole.In the special fair 7-96740 communique of Japan, use 2 sections movable sinkers that needle-bar is shared, and do not use movable yarn guide.
In straight-bar machines, also requirement will be known as the multiple variation yarn of fancy twist yarn etc. as stocking yarn.As the fancy twist yarn, many knots yarn of knotting is arranged everywhere, on heart yearn with the volume yarn loopy yarn etc. of coiling continuously.Also use with winding yarns such as air jets and the strand of making around yarn.These yarns are compared by the common stocking yarn that forms that is twined, spatially bigger expansion, and a part is caught by pinhock and when drawing in needle-bar, cares for easily near the pusher jack the position of decision knitting density etc.
And,, use the plating-knitted of 2 stocking yarns in addition and use many of many thin stocking yarns braidings etc. to weave the situation of many stocking yarns simultaneously as stocking yarn.Under the situation of using this stocking yarn, use the fixedly sinker of being with recess as sinker, when determining loop density, to make the position stability of stocking yarn.But, outstanding or close to the tooth mouth easily when sinker has recess at the sunk part pusher jack, thus care for easilier to pusher jack.As movable yarn guide member in No. 3333304 communique record of Japan Patent, owing to form the shape of drawing in the path that can not interfere stocking yarn, even under the state that enters the tooth mouth, when drawing in stocking yarn, pinhock can not form obstacle yet, thereby to preventing pusher jack is cared in what help does not have.Also consider to make the front end shape of movable yarn guide member to extend in the mode of drawing in the path of interfering stocking yarn, thereby self-evident under the outstanding situation of tooth mouth at pusher jack from the recess of fixing sinker, even under not outstanding situation, stocking yarn is separated with the pusher jack front end.But in decision when pinhock is drawn in needle-bar with stocking yarn during knitting density, stocking yarn is cared at the front end that further enters the movable yarn guide member of tooth mouth than fixing sinker, at the position formation sinker loop that further enters the tooth mouth than fixing sinker.
When the part of the stocking yarn of fancy twist yarn or many yarns was also cared on pusher jack, the part of being cared for might be impaired, and the knitted fabric that knits out also might be impaired.And, being provided with under the situation of 2 sections needle-bars at 4 needle-bar straight-bar machines etc., the relation that enters of the relative tooth mouth of pusher jack is compared with the situation of single hop and is become complicated, and stocking yarn is cared for easily.
