SU445211A1 - Remizopodna carriage with oncoming movement of shafts - Google Patents

Description

one

The invention relates to equipment for weaving and can be used on heald carriages with balance bar.

The famous rem is a lifting carriage with oncoming movement of shafts containing; the balancer, with which balls of shar.nirshto there is a repair hook and support plate; clan.ku pushing each end of the balaisira through the base plate; heddle hook to the lower traverse; one knife for each helix hook, as well as a support bar for heddle hooks and control levers, which are operated by the controls, and which fix heddle hooks in a predetermined position.

However, such a carriage is not reliable enough at high speeds because of the large amount of gaps and hook curvature.

In order to increase the reliability of work in the proposed carriage, the plate and shaft are strengthened by a ball on one UN ball and the fixed traverse is made of two parts located on both sides of the shaft hook.

The contact surface of the tumble hook and knife, on the one hand, and the tumble hook and support bar, on the other hand, is shown in the form of a newer rotation with an axis parallel to the axis of the tumble hook.

The support bar and the knife are installed with a potential: the rotation around the axis parallel to the axis of the tumble hook, while the plan, support plate and fixed traverse have contact surfaces parallel to each other and the axis of the K1 hook.

FIG. Figure 1 shows schematically the so-called agaeem of the heald carriage with the embedding movement of the shafts, the shafts are in the position of the upper shed; in fig. 2 - the same, shims are in the position of the lower os.

The carriage consists of a balancer 1, at the ends of which, with the help of axes 2, the safety hooks 3 and supporting hooks 4 are sharnarno strengthened, the latter, with their direct surfaces 5 and 6, adjoin, on the one hand, fixed traverse 1 7, and, on the other, cTQpon, - to strips 8, making a forward-motion.

A swinging arm 9 interacts with the middle of the balance bar 1, hingedly located on the shaft 10 and associated with a weaving machine hemming.

The hook hook 3 passes between both parts of the fixed cross member 7 and, at the end, has two circular grooves 11 and 12 that interact with the knife 13, which has a corresponding

geo-jerky shape, or with an ojiQp.Hon strip 14. Knife 13 can rotate around its O.SI 15, and also perform reciprocating rolling movement along a trajectory 16. But the supporting strip 14 moves only with a turn-and-do movement of its own 17 Kipyr 17 parallel to axis 15 and axis 2. Plaika 8, and in its motion, describes the pattern 18.

Remizal K | ryuki 3 are interconnected by a spring 19 and are controlled by the control arms 20.

The carriage works in the following way.

The support PLATES 4 lie in an upward position to the fixed cross member 7 or during the movement of the end of the balance bar 1 - to the plate 8. During the movement of the spiky hook 3, the base plate 4 is gripped without s, the azor between the crosspiece 7 and the flame 8, which is rigidly connected 13. Knife plowing 13 Kipyr axis 15 is carried out during the movement of K1r. 3 boxes 1, so that DI1I1 ACT of spring 19, "ryuchki are pushed out by the trailed K | p01M knife 13 to the working zone of the support bar 14. At this, the ground K | Romka knives 13 comes out of a semicircular notch 11 hooks, and he is adored for driving.

Outside of the moving hook 3, the hooked frame of the support bar 14 enters the recess 12 of the shaft cover 3, so that it stops without a gap: between the support bar 14 and the crossbar 7, as a result of which the corresponding end of the ball | Hsa 1 is also held.

The hook hook 3, supplied by the spring 19 in accordance with the protram.M | MY to the knife edge of the knife 13, is locked by the knife 13 and the bar 8 that deflects backwards. Then the hem hook, driven by the knife 13, moves the remieku to the posterior side of the shed. Reverse displacement (resetting the shim to its initial position is carried out by the strap 8 through the oior board 4. During this time, the tumble hook 3, clamped without a gap between the knife 13 and the strap 8, eliminates the shimmer vibration.

The control lever 20, which is controlled from the pro- file: a dimming mechanism, forces the heddle hook 3 to interact with the supporting fusible 14 or with the foot 13.

The knives 13 and the support bars 14 are at the height of the shafts and in the initial position of the first approximately simultaneously BOIKipyr pivots of their axes in order to release the shaft hooks for movement or to fix them in the final position.

As a result of the coincidence of the geometric shape of the 11 and 12 heddle hooks 3 with their similar parts on the knives 13 and the support bars 14, the slip occurs over the entire contact surface.

Due to the use of the base plate 4 instead of the usual semi-circular segment at the end of the balance bar 1, the tumbler hook is elongated, and the ends of the balance bar 1 rest on the yoke 7 or bar 8 by surfaces 5 and 6.
