SU1723219A1 - Carriage of domestic knitting machine - Google Patents

Abstract

This invention relates to a knit machine industry and can be used primarily on domestic machines in hall machines. It makes it possible to increase the reliability of work and the convenience of maintaining the machine. The design of the household carriage in the hall machine is that, in addition to the curving, pressing, lifting, stationary lowering wedges and wedge pins, there is a rotary tab mounted under the stationary lowering wedge, while the axis of the tab is located ne the vertical axis of the carriage. The pressing wedge is made of two parts, with the rear part being able to be sunk. The wedges are located after the kulir wedges in the direction of movement of the needles of the machine on the axes so that in the raised position they are set with their lower edges above the lower areas of the culminating wedges at 0 mm. In addition, there is a carriage guide, made in the form of a cylindrical rod entering the hole with a groove extending along the needle bed, as well as two switching spring-loaded levers that provide quick removal of the carriage. 1 z.p, f-ly, 4 ill.

Description

The invention relates to a knitting machine building industry and can be used mainly on household appliances in hall machines designed for knitting products under household conditions.

The aim of the invention is to improve the reliability of operation and ease of maintenance of the machine.

Figure 1 shows the carriage, view wedge; figure 2 - carriage, top view (cover conventionally not shown); on fig.Z - section aa in figure 2; figure 4 - carriage, side view (needle bed is depicted in. section).

The carriage design is as follows.

A wedge 2 is installed on the housing 1 (Fig. 1) of the carriage, which serves to transfer the needles from the upper non-working to the working position. A wedge 3 and a lifting wedge 4 are fixed to the edges of the carriage. Culinary wedges 5 are installed on the axles with the possibility of rotation under the action of current needles A wedge — tongues 7, spring-loaded with cylindrical springs 8 (FIG. 2), is installed between the edges of the carriage and the kulirny wedges on axles x 6. The lower working edge 9 (figure 1) and the blade 7 in the raised position (figure 1 on the right) can be located on

0.5–3 mm above the platform 10 of the kulir wedge in the minimum setting position. A lifting wedge 11 is rigidly fixed on the housing 1 and a rotary wedge 12 is installed. In the middle part of the carriage, the lowering wedges 13–15 are installed, the wedges 13 and 15 are rigidly fixed on the casing 1, and the wedge 14 is installed with the possibility of translational movement under the action of a needle current. The axis of symmetry of the carriage is rotatably mounted on the axis of the tongue 16, located under the front part 17 of the press wedge rigidly fixed on the body 1, which consists of two parts. The rear part 18 of the pressing wedge is mounted on the axis 19 (Fig. 3) with the possibility of switching in two positions. The axis 19 is provided with two conical grooves 20, 21. The axis is fixed by means of a ball 22 spring loaded 23 placed in the groove of sleeve 24. To move the axis 19 there is a double-arm lever 25 mounted on the finger 2. At one end of the lever there is a button 27 and the other has a groove into which a pin is attached, fixed on the axis 19. A wedge 28-30 (figure 1) is installed in the middle part of the carriage for lowering the needles. In the rear part of the carriage, a guide 31- (Figures 1, 2 and 4) is rigidly fixed, made in the form of a cylindrical rod, equipped at the edges with chamfer 32. The carriage is fixed to the housing 1 of the carriage by means of a bracket 33. 31 is installed in the hole 34 (FIG. 4), extending along the entire needle bed 35. The hole 34 has a groove 36 in which the bracket 33 is located. In the front part of the carriage there are two levers 37 (FIG. 2), which are actuated by springs 38. Each lever 37 is equipped with a spout 39 (figure 4), placed in the groove of the rail 40, mounted on a needle bed 35.

The machine, equipped with the proposed carriage, works as follows.

When the carriage moves from right to left, its guide 31 moves inside the hole 34 of the needle bed 35, and the needles, which occupy the working position (RP), rise first with the left wedge blade 7, and then with the left wedge 11. Then, under the action of the left wedge 13 and the wedge 15 the needles are lowered and their heaps, turning the blade 16, fall under the action of the wedges located in the right side of the carriage. By interacting with the wedges 28, 29 and the curling wedge 5, the needles are lowered and a thread is obtained from the internal yarn guide (not shown). Then, under the pressure of the heel, the needles are raised, turning the right

wedge pin 7 counterclockwise. The path of movement of the current of the needles, which occupy the initial working position, is shown by a dotted line in FIG.

position (PDP), first lift the left wedge 3, then the turning left wedge 12 and move horizontally until their heels come into contact with

0 by a wedge 30. Under the action of the wedge 30, the needle stitches lower a little and, moving the movable wedge 14 to the right, lower the wedges located on the right side of the carriage, first with a wedge 13 and then a wedge

5 29 and by a kulir wedge 5. At the same time, the needles receive a thread from an external yarn guide (not shown), form loops and, raising themselves under the force of a pull, turn the right blade 7 counterclockwise

position shown in figure 1 by the dot-dash line. As a result, in one move

the carriages in looped double-colored knitwear (the needles that occupied the RP, loop the loops of the same color, and the needles that occupied the PDP, - the loops of a different color).

If it is necessary to move the carriage from one to another edge of the needle bed without opening loops, switch the blade 7 to the position shown in FIG. 1 on the right and turn off the rear part 18 of the pressing wedge by pressing the button 27 (FIG. 3). When the button 27 is pressed, the lever 25 turns counterclockwise and raises the axis 19, moving the back part 18 of the pressing wedge to the off position. The axis 19 is fixed due to the fact that the ball 22 passes from the groove 21 to the groove 20. FIG. 3 shows the off position of the rear part 18 of the pressing wedge. When moving the carriage without drawing, for example, from left to right, needle needles pass under the right

5 with a wedge-tongue 7 and turn the right-hand wedge 5 clockwise. Then the needle weights are passed over the recessed rear part 18 of the pressing wedge, lower the left-hand wedge and move

0 further, lift the left blade 7. In those cases when it is necessary to turn off the carriage, for example, when it is jammed, press the left and right levers 37, overcoming the action

5 springs 38 and the removal of the levers on themselves (Fig.2,4). In this case, the bent nozzles 39 of the arms 37 exit from the rail 40 of the needle bed 35 (Fig. 4). Then, the carriage is turned counterclockwise around the cylindrical guide 31, as a result of which the wedge is above the needle stitches, and the carriage retracts to the edge of the needle bar.

As a result of using the proposed carriage design, the reliability of the machine operation is increased due to the guaranteed passage of the needles along the trajectory necessary for the looping process. In addition, the serviceability is improved as the force required to move the carriage decreases, and it becomes possible to turn it off at any place on the needle bed.
