CS224063B1 - Lock system of circular knitter for manufacture of hosiery hosi - Google Patents

Abstract

The invention relates to a lock system of a circular knitting machine for making hosiery fabric, for the actuation of the needles, in which axially movable loop-forming and counterlock parts connected to one another are arranged in each knitting system. The object of the invention is to achieve a possibility of an optimum quiet run of the needle butts in the event of changes in stitch density during high machine speeds. According to the invention, to achieve this object, there is arranged on each counterlock part a pivotable lock part, the arm of which is so supported on an immovable lock part that, in the event of a pronounced reduction in the height of the loop-forming lock part, the pivotable lock part covers the counterlock part.

Description

The present invention relates to a lock knitting machine for hosiery and the like. for. · Controlling needles where in any knitting system. they are arranged axially together. · Movably coupled. retractable locks ^and slips.

Hosiery knitting machines are known where in individual knitting systems. the counter-grains are solved so that. · A short 'lifting edge' is formed behind the hauling point, with further lifting being necessary. secure via meeiplatin · a. 'them. due to the discernment. Due to the high speed of knitting, it is necessary to precisely align the working edges of the platinum and needle needles in order to avoid hitting between the cooperating needles and the melamine. This circumstance is particularly problematic. when changing the density of the knitted fabric, when the axial position of the retractable locks and the alignment locks changes, and the appropriate angle of the collision changes. and '·· resulting'. the force stress between the needle and the mezzplatin and optionally the platinum. Thus, due to the change in density, the 'optimum' course is changed. needle nodes _; and • does not calm them down, which may lead to. breaking knees.

The object of the invention is. Basically · remove. , above. listed. The disadvantage of this is that, in each case, a pivoting lock is provided on each of the slides, the arm of which is supported on the stationary locking part, so that with a greater reduction of the retracting lock the pivoting lock overlaps .

The arrangement of the locks according to the invention is in any case provided. 'shown in the drawing',

224 063 FIG. 1 schematically illustrates the position of the retracting lock, the anti-lock and the pivot lock and the course of the needle knuckles at the minimum needling of the needles, FIG. 2 is the same as FIG.

The known single cylinder circular knitting machine for the production of hosiery or the like is provided with a known needle cylinder (not shown), in the grooves of which needles and other sinkers (not shown) are provided. together axially movable countercams spřažen.y Na 2 · ^e j mounted on the pivot 2 * pivotable lock 4, which arm is supported on the swivel pin 5 lock 2, which is controlled from the control drum into a tuck or closing position. A locking ring 6 is provided for guiding the needle butts 1 and the sinkers (not shown).

The function of the lock arrangement described above is as follows. The needle cylinder rotates in the S direction. The retracting lock 2 and hence the counter-lock 2 are in the up position and the needles are thus retracted minimally. The needles 1 of the needles are retracted by the retract lock 2 and are lifted beyond the retraction point by the lifting edge 31 of the counter-lock. When performing larger sweep begins edge gimbal lock 4 overlap the lifting edge 31 takes counter-cams 2 and thus lifting the butts of the needles 1, as shown in FIG. 2. This overlapping is possible because with decreasing countercams 2 ® ^e rocker arm lock 4 it rests on the pin 2 * ^{and the} pivoting lock 4 is rotated clockwise. In the case of maximum hauling, the needles 1 of the needles are also guided by their upper edge, i.e. the closed channel, which forms the edge of the pivot lock 6 and the edge 2 of the retractable lock 2,

An advantage of the invention is that the needle pegs are guided smoothly along the edge of the lock after leaving the retractable lock by the pivot lock, which is automatically adjusted with a change in haul. This ensures their calming, especially at high speeds. Within the scope of the invention, it is possible that the arm of the pivot lock 4 rests on another fixed lock part, for example a ring 6, if the machine is not equipped with a pivot lock 2.
