Abstract

The present invention relates to a cam system for two cylinder circular knitting machines for manufacturing hosiery and similar goods, said machine comprising at least two feeds which are engaged during reciprocatory knitting. The present invention permits to maintain constant knitting conditions, and its subject matter consists in that in each feed is mounted within the path of the lower butts of the needles or sliders a stationary loft cam and a right cam 5, 6 and 11, 12, as well as a central cam 7, 13, while within the path of the upper butts of the needles or sliders is mounted a left cam and a right cam 8, 9 and 14, 15, and between the neighbouring left and right cams of the neighbouring feeds is mounted a radially movable triangular rising cam 17. <IMAGE>

Description

(54) Interlocking system of two-cylinder circular knitting machine for production of sock goods etc.

The invention relates to a lock system of a two-cylinder circular knitting machine for the manufacture of sock goods and the like with at least two knitting systems fastened during return knitting where they are in the needle cylinder. to control the choice of double-needle needles of another sinker.

There are known two-cylinder knitting machines for production - sock goods with two separate filling systems, each system comprising a central pulling lock and right and left pulling locks for operating the upper knees of the sinkers in the lower needle cylinder. The retractable locks are arranged vertically movable to control the density of the article. A radially infeed triangular is arranged between the two knitting systems. lifting lock θ and related. fixed lifting / / locks for operating the upper butts of the needle jacks, or a triangular lifting lock in the path 1 of the flip-flops of the third. ^These Tevye ia right stitch cams j sou ujímače then arranged.

These arrangements of the locking system have the disadvantage that the retractable and / or the retractable locks have a drawback. In order to ensure densities, the eye-locking locks move axially, thereby changing the position of the retractable edges and hence also the thread laying conditions, which has an adverse effect on the quality of the knitted fabric and its appearance. Furthermore, the circumferential length of the locks in the knitting systems is also affected, and especially for coarse cutting machines, it is very difficult to place the knitting systems around the periphery of the needle cylinder to maintain optimal knitting conditions, especially when reversible two-system knitting. heel, respectively. spike.

SUMMARY OF THE INVENTION It is an object of the present invention to overcome these disadvantages and to provide a simple locking system which is particularly suitable. for two-roll roughing machines. This is essentially accomplished by the fact that in each knitting system there is a fixed left and right retractable lock in the path of the lower knees of the guide sinkers and a fixed central retractable lock and θ in the path of the 'upper knees of the guide sinkers of the left'. a right density lock, wherein a radially infeed triangular lift lock is arranged between adjacent left and right density locks of adjacent knitting systems.

The lock system according to the invention is shown in the drawings in which: FIG. 1 shows the locks of two knitting systems enabling reversible knitting. which operate the guide sinkers in the lower needle cylinder with. 2 are the same as θ of FIG. 1, but the knee tracks are marked for the opposite direction of knitting.

The guide roller 3 for receiving the double-needle needles 4 and other sinkers (not shown), for example interfaces 1 and selectors, is mounted in the axial grooves 2 of the upper cylinder and the needle roller. The guide sinkers 3 are provided with upper, knees 31 and lower knees 32. The machine is equipped with two knitting systems. ? j

The first knitting system comprises in the path of the lower knees 32 of the sinkers 3 a fixed left-puller lock 5, a fixed right-retractable lock 6 and a fixed central pulling lock 7. Above these locks an axially sliding left density lock is arranged. 8 and the right density lock 9, and between them a fixed auxiliary lift lock 10 is still arranged. Also, the second knit system has fixed left and right retracters in the path of the lower butts 32 of the guide sinkers 3. chateaus ^{Y 11} 'and ¹² and the middle of ^t Aho ^ad lock 13! and - in the path of upper butts 31 axially • (movable ^l Eve and right ^h ustotový of ^{MEK 14,} res ^p. 15 ^{- -} (a stationary auxiliary zvedad lock 16 .

The platinum guide is horizontal in the closing position. Lower nodes? 2, | then it strikes the middle puller lock 13 and pulls the guide sinker 3 - the double-head needles 4 into the pulley position. On the next movement, the lower knees will hit! 32 on the left retractable lock 11 and the double-head needles are retracted into the retracted position, the stitches forming the stitches. In the exemplary embodiment, the left density lock 14 is set to take over from a certain moment of retraction and determine the depth of the haul so that the depth of haul is controlled by the action of the density lock 14 on the upper nodes 31 as seen from the course of the tracks. b., t ·

Further, the double-headed needles 4 are pulled by means of the lower knees 32 right. the edge of the central pulling lock 7 reaches the position. The pulling of the double-needle needles 4 is effected by means of the lower nodes 32 on the left retract lock 5, again as in the previous knitting system, the retraction takes over the left density lock 8 acting on the upper trunk 31 and the engagement as is; seen on the course -draha, respectively. b, the staple yarns are formed by stitches. There are also two-headed needles; j 4 lifted by means of the lower knees 32.

The lock 21 dp closes the positions and is ready for knitting in the first knitting system.

i For reversible knitting 'heel respectively. spike. The needle cylinder 1 rotates in the directions S1 and S2 (FIG. - 2) and both knitting systems are in operation. The double-headed needles 4 are in a known manner divided into working and non-working and also in a known manner. it carries out the addition and addition of double - head needles 4 by known unrecognized yokes located in the path of the upper knees - 31 above the density locks 8, 9,. 14 and 15 and a known not shown puller located outside of the systems. When the needle cylinder 1 is rotated in the direction S1 ', it is confused. in the same way as rotary - knitting. When rotating in the direction S2, the double-headed needles 4 are actuated substantially mirror-like to the direction S1, as will be described hereinafter.

The double-needle needles 4 of the beginning of the working double-needle group are in the locked position, with the lower and upper nodes 31 and 32 coming from the left side to the first knitting system in lanes d. pulled by the central pulling lock 7 into the laying position. The retraction of the double-needle needles 4 'is effected by means of the lower nodes 32 on the right retracting lock 6, the final drawing phase being taken over by the right density lock 9 which acts on the upper nodes 31 of the guide sinkers 3. b and stitches are formed from the laid thread. Further, the double-headed needles 4 are lifted by means of the upper knees 31 by means of a triangular lifting lock 17 along the path d and into the locks behind the lower nodes c of the guide sinkers 3 by the edge 11 'of the left retractable lock. - lowered by the knees 32 on the central pulling lock 13. - Retracting. The double-needle needles 4 are first carried out by means of the lower nodes 32 on the right retract lock 12 and the final phase is again taken over by the right density lock 15 acting on the upper nodes 31; 3, as can be seen from the course of the paths d, β, respectively. c, wherein the stitch threads are formed into stitches by means of the right lifting lock 20 by means of the lower knees 32 - the double-head needles 4 are then raised to the position closures. As soon as the last double-headed needle from the working group has reached this position, the mowing direction of rotation from S2 to S1 is confused with the method described above.

An advantage of the described invention. - is the fact that - the density of the knitted fabric can be controlled at a different level than the basic control of double-needle needles, so that the conditions for putting the yarn into the needles always remain

the same, since the path of the double-needle needles between the central pulling lock and the pulling lock in the knitting system is the same at any kind of density. Also by providing rigid retractable
