The invention relates to textile industry weaving equipment and, in particular, to batone weaving machinery.

The purpose of the invention is to simplify the design and expand the technological capabilities.

Battalion mechanism contains reed; 1 (Fig. 1). Berdo is fixed on the slider 2 by means of the axis 3 and the plate

4 fixed on the reed with a slot

5. The guides 6 for the slider 2 are vertical. On the slider. roller 7 is mounted. The roller 7 is in contact with the cam 8, which is rigidly fixed on the shaft 9 and connected by means of gears 10 to the ratchet wheel 11, which is loosely mounted on the shaft 9, the bar 12 of the batana is mounted on the points 13 and connected by means of a crank 14 through the connecting rod 14 15 of the main shaft 16. The axis 17 of the pawl 18 is fixed to the frame of the machine 19 by means of a bolt 20. On: a section from the edge of the fabric 21 to the infant 22 the fabric is horizontal. In the grain, 23, the weft thread 24 is located. The warp threads of the base 25 are punched into the helix 26 and are located in the lamella fixture 27.

The ratchet wheel 11 (Fig. 2) is mounted on the hub 28, which is its; , t is freely mounted on the shaft 9. At the other end of the sleeve 28 is fixed gear. A gear transmission contains five gears, the last of which is slave and is fixed to the shaft 9, on which a rigid gear 3: cam 8 is attached.

The mechanism works as follows.

When the main shaft rotates, about the shaft 16 (Fig. 1) reed 1 reaches the edge of the fabric 21 and nails the weft thread 24 to the edge. When the batane departs from the front position, the ratchet wheel 11 is displaced relative to the pawl 18, the axis

threads. The working stroke of the bird became shorter despite the fact that the stroke of the batan remained the same,

When the batane departs from the front position, the storage wheel 11 is turned again by the action of the pawl 18 and by means of the cam 8 reed up.

At the next turn of the main shaft of the workers, the stroke of the reed will become even shorter by the same amount as in the previous turn, because the profile of the cam 8 is made, for example, by Archimedes' helix, which ensures a uniform waste, reed, and a shortening of the reed stroke by predetermined value

After several revolutions of the main shaft of the machine, cam 8 will make a fifth turn. At the same time, roller 7 falls onto a small cam radius. At the next turn of the main shaft, the working stroke of the reed becomes long and all the previous heads move, and are placed one above the other in a vertical plane. Then the spin cycle is repeated.

Thus, a variety of combinations of short and long Byrd strokes is provided.

Firstly, this is achieved by changing the angle of rotation of the cam 8 in one revolution of the main shaft of the machine. If, for example, the cam is turning from 90 degrees per one revolution of the main la, then the full revolution of the cam is done for 4 revolutions of the main shaft. Then the laying cycle is four, and the reed has three short ho (differing from each other by

which is fixed on the frame 19. The dog's divided value) and one long one.

The tooth engages the tooth of the ratchet wheel, and it rotates, transmits the rotation through the gears to the shaft 9, on which the cam 8 is fixed. The cam acts on the roller 7 and moves the slider 2 upwards along the guides 6. Reed 1 moves upwards. Then Berdo moves to the back position and Noah

threads. The working stroke of the bird became shorter, despite the fact that the stroke of the batan remained the same,

When the batane departs from the front position, the ratchet wheel 11 rotates again under the action of the pawl 18, and through the cam 8 the reed is shifted upwards.

The next turn of the main shaft of the working stroke of the Byrd. It will become even shorter or shorter by the same amount as the previous turn, since the profile of the cam 8 is made, for example, in an Archimedes spiral, which ensures a uniform waste, byrd, and shortening of the Byrd stroke to a certain predetermined value.

After a few revolutions of the main shaft of the machine, the cam 8 will make a full turn. At the same time, the roller 7 is lowered by a small cam radius. At the next turn of the main shaft, the working stroke of the reed becomes long and all the precursors shift, and are placed one above the other in a vertical plane. Then the spin cycle is repeated.

Thus, a variety of options for combining short and long Byrd strokes is provided.

First, this is achieved by changing the angle of rotation of the cam 8 in one revolution of the main shaft of the machine. If, for example, the cam is rotated by 90 for one revolution of the main shaft, then the full revolution of the cam is made in 4 turns of the main shaft. Then the laying cycle is four, and the reed has three short strokes (differing from each other by a certain amount) and one long one.

The gear ratio from the ratchet wheel 11 to the cam 8 can be changed by means of interchangeable gear 10, so that the cam will make one hollow revolution per five revolutions of the main shaft. In this case, the ratio of long and short moves will be 1: 5.

Another way of changing the ratio of short and long strokes is to replace the ratchet wheel 11, the new ratchet mechanism having a different number of teeth, but the same diameter. Simultaneously with the installation of the ratchet mechanism, the axis 17 of the pawl 18 is adjusted (Fig. 1 to ensure that only one tooth of the wheel is gripped by the pawl. The bolt 20 is loosened, the axis 17 is displaced relative to the frame 19 and fixed. The rotation angle of the ratchet wheel for one revolution of the main wheel the shaft, the machine will change, and therefore the angle of cam rotation will also change, and another combination of short and long stroke will be obtained.

In fact, one cycle of operation of the mechanism can be up to 25 revolutions of the main shaft.

The machine can be processed to specify a yarn of different linear density, of different thickness. In this case, with the same stroke ratio, the amount of change in stroke for one revolution of the main shaft should be changed. For this purpose, reed 1 (Fig. 1 and 2) is mounted on axis 3 and secured by means of plate 4 with slot 5, the slot being made along an arc of a circle centered on axis 3. By loosening the mount, you can turn reed 1 and install it under another angle to the horizontal plane. In this case, with the same magnitude of the Byrd displacement in the vertical plane under the action of the cam 8, the change in the magnitude of the stroke will be different.

The proposed batten mechanism provides a variety of weft yarns in the fabric depending on the linear density of the weft yarn and the average weft yarn creates conditions for the fabrication of single-layer weft fabrics, terry fabrics and multilayer layered frame fabrics0
