Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a warp pattern setting device for a stockinette circular knitting machine in which a warp pattern is combined separately from the ground weave in the circular knitting machine.

Structure of a conventional example and its problems FIG. 9 shows an example of a device for supplying warp yarns to a stockinette circular knitting machine and producing a warp pattern. In this device, a spring 41 is placed on a cylinder 40 for knitting needles.
A rotating arm 44 having a thread feeding hole 43 for the warp threads 42 is pivoted and is urged to always return to its original position by rotating, and protrudes from the fixed part as the knitting needle cylinder 40 rotates. The stopper 45 contacts the rotating arm 44 and rotates the rotating arm 44 against the elastic force of the spring 41 to displace the warp yarns 42. In response, the knitting needles 46 move up and down. There was a method of knitting by intertwining the warp threads with the knitted fabric. However, in this device, the displacement of the warp yarns by the rotating arm 44 only causes the warp yarns to become entangled with the knitting needles 46 due to the horizontal displacement caused by the horizontal rotation of the cylinder 47 for knitting needles. is unstable, and when the rotating arm 44 comes off the stopper 45 and returns to its original position by the force of the spring 41, it may give unnecessary tension to the warp threads 42 or become unreliably entangled with the knitting needles. It was seen. In FIG. 10, 49 indicates a stockinette knitted fabric, and 48 indicates a vertical pattern.

Purpose of the Invention The present invention is an ordinary stockinette knitted fabric, which differs from a fabric with a vertical pattern in that the warp yarns are supplied separately from the knitted fabric, and when the yarn finger cylinder rotates, the warp yarns are supplied by the yarn fingers and yarn stopper. The present invention aims to provide a warp pattern setting device for a stockinette circular knitting machine that displaces the warp yarns in both vertical and horizontal directions to ensure entanglement with knitting needles, realize reliable warp pattern setting, and stable yarn feeding. .

Structure of the Invention The present invention relates to a circular knitting machine that knits using latch needles, which includes a cylinder for yarn fingers centered on a spindle, a cylinder for yarn fingers provided at the periphery of the cylinder, having a warp hole at the tip, and rotating by a cam. A plurality of yarn fingers, a warp bobbin stand, and a cylinder for knitting needles are provided, each of which is set to rotate synchronously by a spindle, a transmission shaft, and a gear, and a cam mounting plate for the yarn fingers connected and fixed to the metal around the spindle, and a plurality of cylinders from the bed. A sinker ring, a sinker cam ring, and a knitting needle cam box are connected to the metal through the book support and the connecting rod, and are fixed to the cylinder for knitting needles, and the sinker cam ring and knitting needle cam box are fixed to the bed. A yarn stopper is provided which is bent and has a rounded portion at its edge, and a pattern formed by the warp yarns is combined with a ground structure formed by the ground yarns by means of the yarn finger, the yarn stopper, and the knitting needles moved by the knitting needle cam.

Therefore, when the warp yarn is held in the warp hole at the tip of the yarn finger, and the knitting needle cylinder and the yarn finger cylinder rotate in synchrony, the yarn finger is driven by the cam, the warp yarn moves outward and upward in an arc, and is moved by the rounded part of the yarn stopper. Now I can reliably tangle it around the knitting needles.

DESCRIPTION OF THE EMBODIMENTS FIG. 1 is a cross-sectional view of the main parts of the warp pattern setting device of the circular knitting machine of the present invention, in which 1 is a spindle, 2 is a metal around the spindle 1, and 3 is a cylinder for yarn fingers, which is attached to the spindle 2. ing. Reference numeral 4 denotes a yarn finger, which is fitted and supported in a part of a large number of vertical grooves 5 provided on the outer peripheral edge of the yarn finger cylinder 3 at a position where a warp pattern is exposed. As shown in FIG. 2, this yarn finger 4 is rotatably supported at a fulcrum 4' and has a warp hole 4'' at its tip. Reference numeral 6 denotes a round band, which is fitted into the shaft support 4 of the yarn finger 4. The yarn finger 4 is attached to the outer periphery of the yarn finger cylinder 3 and is rotatably supported by a fulcrum 4'. 7 is a warp bobbin stand which is rotatably supported by the metal 2 and connected to the yarn finger 3 by a gear 8. ,9,1
They are designed to rotate synchronously via 0 and 11. 12 is a warp bobbin, 13 is a warp thread, and 14 is a cam mounting plate, which is connected and fixed to the metal 2. Reference numeral 15 is a cam holder, and 16 is a cam which is attached to the cam holder and is adapted to alternately act on the upper and lower stages at positions across the fulcrum 4' of the yarn finger 4. 17 is a bed, 18 is a cam box, 19 is a cam for knitting needles, 20 is a sinker cam ring, 21 is a sinker ring, 22 is a sinker,
Reference numeral 23 indicates a thread guide mounting base for ground knitting, and reference numeral 24 indicates a ground thread.
25 is the yarn stopper attachment ring, 26 is the tip
This is a stopper which is fixed on the sinker cam ring 20 and has a rounded part 26' formed at a bent part bent at 90 degrees. A plurality of columns 27 are provided and fixed to the bed 17, and the metal 2 is supported and fixed via a connecting rod 28. A transmission shaft 29 passes through the pillar 27, and transmits power from the drive source to gears 30,
The knitting needle cylinder 32 is driven through the needle 31, and the spindle 1 is rotated through the gears 33 and 34. 35 indicates a knitting needle. In addition, ground thread 2
The bobbin No. 4 is separately provided near the circular knitting machine, passes through the thread path attached to the thread path mounting base 23, and connects to the sinker 2.
2. Knit the ground structure using the knitting needles 35.

The transmission shaft 29 and gears 30, 31, 33,
34 to the knitting needle cylinder 32, and the spindle 1 and gears 8, 9, 10, 11 to the yarn finger ring 3 and warp bobbin stand 7.
They are designed to rotate synchronously. On the other hand, cam box 18, sinker cam ring 20
and the cam mounting plate 14 are each fixed.
Therefore, in accordance with the rotation of the yarn finger ring 3, the yarn finger 4 is rotated about the fulcrum 4' by the cam mounting plate 14 and the cam 16 of the cam holder 15. The warp yarns 13 move in an arc shape to the outer upper position through the warp holes 4'' at the tip of the yarn finger 4, and supply the warp yarns 13 to the knitting needles 35.The supplied warp yarns are supplied to the knitting needles 35 by the fixed yarn stopper 26. Hold the position. At the position where the knitting needles 35 necessary for patterning have secured the warp threads 13,
The yarn finger 4 is moved by the cam 16' to its original position inwardly and downwardly. By moving the position of the warp hole 4'' at the tip of the yarn finger 4, the warp yarns 13 are guided to the rounded sloped surface at the tip of the yarn stopper 26, and are reliably entwined with the knitting needles 35.In this way, the warp yarns are arranged in an arc shape and in the vertical direction (first direction). Figure 3 A→B)
At the same time as the warp yarns 13 are displaced, the arcuate portion of the stopper 26 ensures that the warp yarns 13 are entwined with the knitting needles 35. This entanglement of the warp yarns 13 allows the knitting needles 35 to create a pattern in the warp direction using the warp yarns, which is combined with the ground weave.

The relationships among the yarn fingers 4, warp yarns 13, stoppers 26 and knitting needle cams 19 are as shown in FIGS. 4 to 6. 5A is a sectional view of the stopper 26 taken in the radial direction, and FIG. 5B is a sectional view taken in the tangential direction of the circumference. FIG. 6A shows the positional relationship between the cam 36 and the knitting needles 37 when knitting the ground weave, and FIG. 6B shows the state in which the warp yarns 13 are entangled with the knitting needles 35. In FIG. 8, numeral 38 indicates a stockinette with a warp pattern, and numeral 39 indicates a driving source.

Effects of the Invention As described above, the present invention includes a spindle 1, a transmission shaft 2,
9 and gear 8, 9, 10, 11, 30, 31,
33 and 34, yarn finger ring 3;
Warp bobbin stand 7 and knitting needle cylinder 32
rotates synchronously, and the yarn fingers 4 and knitting needles 35
, thereby making it possible to use the warp threads 13 separately from the ground threads 24 to reliably realize a vertical pattern using the warp threads. In particular, it has become possible to guide the warp yarns to the rounded portion 26' of the stopper with the yarn fingers and to reliably entangle them around the knitting needles. Therefore, unlike the conventional example, it does not have a spring or other structure that applies sudden tension, so it is stable and there is no risk of cutting or distorting the thread. The knitting needles for the ground yarn and the knitting needles for the warp yarn can be assembled into the knitting needle cylinder in accordance with the pattern, and the yarn finger can be set accordingly and driven by a cam, so any vertical pattern can be created. It is now possible to combine them to provide beautiful and dignified stockinette stitches.
