Abstract

The invention relates to textile machinery, can be used on weaving machines and allows for the expansion of technological capabilities. When the reed approaches, the tension sensor issues a command to turn on the leading coupling half 2, which enters into force closure with the driven coupling half 7, and through gears 4, 28, 29, 30, 31, 32, 33 the rotational movement is transmitted to the shaft 34 which removes tissue from the formation zone. At the same time, the single-shoulder lever 10 with the pawl 13 rotates after the ratchet 3 until the fork 11 stops against the edge of the shackle. The ratchet 3 rotates until the coupling half is turned off. After the weft yarn is attached, the driving coupling half 2 is turned off from the interaction with the driven coupling half 7, and the product control changes the direction of rotation, i.e. Under the action of tensioning the base, a partial reverse rotation occurs. At the same time, the ratchet tooth 3 rests on the pawl 13, turns the single-arm lever 10 up to the stop of the fork 11 through the compressed spring to the stop, and the regulator stops. Since the moment of the release of the fabric corresponds to the extreme forward position of the bird at the moment of the surf, the last specified thread continues to experience the effect of the bird due to the tension of the base and some distance accompanies it in the return movement. In this way, the time it takes for the reed to act on the weft thread to the edge of the fabric is increased. 1 hp f-ly, 3 ill.

Description

The invention relates to textile machinery and can be used on weaving machines.

The purpose of the invention is the expansion of technological capabilities by increasing the time of the impact of the reed on the weft fabric that wears to the edge.

The figo presents kinech, the actual scheme of the commodity controller; FIG. 2 is a view A in FIG. I-; on figs - view B on figo2o

A weaving loom control consists of a longitudinal shaft 1-. JQ (figo) on which are located rigidly fixed drive coupling half 2, ratchet wheel 3, gear wheel 4, freely mounted on bearings 5 and 6 of the slave 7, on which gear wheel Sa- is rigidly mounted On the opposite side of drive coupling half 2 and ratchet wheel 3 on the shaft 1, by means of the bearing 9, a single-arm lever 10 is mounted, on which the zilka P is attached, and on the axis l2 a pawl 13 (fig and 2), spring-loaded 14o Spring The slot of the fork 11 enters the arc-shaped direction Yush: 11 acts on single-shouldered lever.ag 10 and st Remitts turn it clockwise On the arcuate guide 5 in order to adjust the angle of rotation of the one-arm lever 10 there is a limitation - a chuck 17, which is fixed in the holes 19 by means of a pin 18; which, by means of the bracket 22, is fastened to the frame of the machine 23r. The control voltage on the inlet half of the coupling 2 is supplied by means of a candle 24 mounted on the square Zlc. The flywheel 25 is rigidly fixed on the shank of the longitudinal shaft 1, designed for manual operation. This commodity regulator Permanent vertical movement of the commodity regulator is obtained from the machine transverse shaft 26 through gear 27s in engagement with gear wheel 8 which is converted by means of an electromagnetic clutch into discrete gear and transmitted through gears 4 28, 29 |, 30, 3i, 32 and 33 on the wall

The driving coupling half 2 is controlled by a tension sensor, consisting of a contactless switch 35 mounted on a double-arm lever 36 (Fig 2 and 3) which is in contact with the tissue through a spring-loaded rod (not shown) with a contactless sensor consisting of two sectors 37p 38 and 9 are made with the possibility of displacement relative to each other, depending on the required fabric tightness and fixation by means of a screw and mounted on the machine’s cross shaft 26 by means of a coupling 40 o

Commodity regulator works as follows

From the machine drive (not shown) through the transverse shaft 26 by means of a gear train 27 8, the rotational movement is continuously transmitted to the driven half coupling 7c. When the machine bard approaches the forward position, the warning lamp 37 enters the slot of the proximity switch 35J and sends a command through a standard control unit (not shown) ) on the inclusion of the leading half coupling 2 Leading by

Lumufta 2 enters into a joint lock with an driven coupling half 7 and through

the rotational movement is higher than that of val 3, which is j. turning, pulls the fabric out of the shank of the formation. At the same time, under the influence of the spring 16 on the fork iJ, the single-arm lever 10 e with the pawl S3 rotates after the ratchet 3 fixed on the shaft i with 2 shows a dash-dotted line) Ratchet 3 continues to rotate until the half-coupling 2 is turned off, the angle of rotation of which is set by the alarm 37 and corresponds to a certain amount of withdrawal of fabric L, slightly larger than 5 required to obtain tissue with a given density. When the detector 37 comes out of the slot of the contactless switch 358 which corresponds to the moment of the gear 5, the leading half-coupling 2 is turned off from the interaction with the driven coupling half 7 and the commodity control changes the direction of rotation, the partial reverse rotation takes place under the action of the base tension At the same time, the ratchet tooth 3 rests on the canister 13, turns the single-arm lever W up to the stop of the fork 11, through the compressed spring 16 into the stop 17, mounted on the arcuate guide 15, and the remaining a commodity regulator In the return stroke of the fabric by an amount equal to J unnecessarily allocated initially is returned to the forming zone, so as the point of fabric soot- holiday; This is due to the extreme forward position of the reed at the moment of surfing, then the latter continues to experience the impact of the reed due to the tension of the base and a certain distance corresponding to the angle of the partial reverse rotation, also accompanies it in reverse motion by Tak.On pasoMs

The VII Byrd on the thread being nailed and the dynamic loads on it decrease. at the moment of the surf. Sliding signaling device 37 and arc-shaped guide 15 with limiter 17 are aligned so that the given tissue density is determined by the difference J, - tPj, where сГ, - is the amount of tissue removal j

The processes described are repeated at each revolution of the main shaft.

The proposed commodity regulator allows you to expand the technological. weaving capabilities and

produce tarpaulin fabrics with a co-efficacy coefficient of more than 4 without reducing labor productivity and resisting metal consumption
