Description

In the proposed apparatus for the manufacture of bars of yarn, for the purpose of mechanically shifting the strands during the weaving of the bar, three rotating frames with coils are used, and a device consisting of two wheels, the crowns of which are alternating in different directions of movement, is used to communicate the latter periodically provided in four sections with teeth, transmitting, via intermediate gears, intermittent motion to the wheels of the satellites enclosed in swiveling cages, the ends of which have grooves for processes of the coil frames.

In the schematic drawing of FIG. 1 shows a side view of the apparatus; FIG. 2-horizontal section of it; FIG. 3 is a top view of the apparatus with one thing: an intermediate arrangement of the frames during the operation of the apparatus.

The machine for making bars 1 of yarn consists of three frames 11, 12, 13 with KaTyoiKaMirS, 6, 7, 8, 9, 10 with the yarn inserted into them, from which yarns 2, 3, 4 are made. The frames 11, 1-2 and 13 are inserted into the grooves with which the rotary clamps 37 and, 38, fixedly mounted on the oc55ix 16 and 20, are provided.

On the same axes, gears 23 and 26, respectively, are wedged, receiving rotation in opposite directions from the main shaft 19 through a system of gears 25, 24, 29, 28, 22 30, 27 (Fig. 1). The rims of the wheels 22 and 27 each have four protruding portions,, c, d, provided with teeth that engage with the gears 23 and 26 so that the latter rotate only half a turn during each engagement with each of the portions. The wheels 23 and 26 do not engage simultaneously with the protruding portions of the rims 22 and 27, but alternately, which causes periodic, alternate rotation of the clips. This intermittent rotation is transmitted to the frames via intermediate fixed wheels 14 and 15 with internal engagement for the satellite 33-35, which are enclosed in sleeves 37 and 38 rotatable around the center of the wheels and provided with slots for the ends of the coil frames at the ends (Fig. 3). In order to move the frames 11,12,13 in the slots of the clips 37.38, there is a slider consisting of a pin 42 having a reciprocating movement in the rotary notch 43, integral with the gear 49, provided with a discontinuous gear.

The wheel 50, also having a discontinuous gearing, is designed to rotate the groove 43 of the beads and, for this purpose, is driven into periodic rotation by means of a chain 53 from the toothed sectors 54, 55 that engage with the toothed sections of the wheels 22, 27. the lead from the groove 43 serves as a device consisting of the toothed sectors 41, 51 that engage with the toothed sections of the wheels 22, 27 and are wedged on common axles with gears 40 and 52. The latter transmit periodic rotation from the toothed sections of the wheels 22 and 27 through a chain 39 gear 44 which is keyed on the same axis 56 to a crank 47 and a rod 45 pivotally connected with pin 42 overhead LCI.

The apparatus is driven from the main shaft 19 with gear 25 stuck on it, transmitting a rotation to the whole device through a system of gear wheels. Let the frames 11, 12, 13 at some point in the operation of the apparatus assume the position shown in FIG. 1 and 3, and the gear system at this time is positioned as shown in FIG. 2. When coupling a portion b of the wheel 22 with the wheel 23, the latter, rotating, will rotate the yoke 37 with the frames 11 and 12 on it (Fig. 3). In this rotation, the strand 2 will intertwine with the strand 3 until the wheel span 22 of the wheel 22 comes out of the clutch with the wheel 23. During the clutch engagement of the segment b and the wheel 23, the latter will turn half a turn and stop. At the same time, the section a of the wheel 22 will engage with the toothed sector 44 and, turning the latter, thereby through the gear 40 and the chain 39 rotates the gear 44 and the crank 47 stuck on the same axis 56 axis. finger 42 shoulder strap.

After that, the wheel 27 will enter the area and into engagement with the toothed sector 55, turning at its last. In this turn, sector 55 will turn the latter, and with it the extended finger 42 shoulder strap, which will move the frame And out of its groove, when turned, by means of the chain 53 and the wheel 50 engaging with the gear 49.

the clips 37 into the groove of the clips ZV- After that, the wheel 27 will engage simultaneously with two projections: the protrusion a with the gear wheel 26, and the projection b with the gear sector 51, turning them. With this rotation, the gear wheel 26 will turn half a turn and thereby rotate the holder 38 mounted on the same shaft with frames 11 and 13 by 180 °. During this rotation, weave the strands 4 and 2 just like in the previous case. with the yoke 37. When turning the toothed sector 51, the finger 42 will be extended by shoulder strap in the same way as in the previous case. After that, the wheel 22 will engage with the protrusion a with the toothed sector 54, which, when moving through the chain 53 and the wheel 50, will turn the shoulder strap, and the last finger 42 will move the frame 13 from the yoke 38 to the yoke 37.

The described operations during the continuous movement of the main shaft will be repeated in the specified sequence, and thereby the weave of strands 2, 3, 4 forming the bar 1 will be mechanically interlaced.

The subject of the patent.
