SU67961A1 - Weft probe for weaving machines - Google Patents

Description

Weft probes for weaving machines, which automatically measure the layer of weft yarn on the spool of the weaving loom to detect its descent and act on the machine stop mechanism, have the disadvantage that a relatively large percentage of weft yarn in the form of fillings for spools.

The present invention eliminates this drawback, provides the ability to work on spools with reserve winding and without it, and has the distinctive feature that the weft probe is made in the form of a spring-loaded slider, the pointed end of the interacting with the yarn or with the spool body and carrying the rotary axle. x, diametrically located, adjustable tentacles 4. They touch their teeth only with the yarn on the bobbin and when reaching the established layer of yarn on it diverge in opposite directions for control through the ki ematicheskuyu transmission with an automatic machine shutdown.

FIG. 1 shows a section of the weft probe and the spool of a shuttle with winding; in fig. 2 - probe at the time of the tentacles; in fig. 3 shows the design of the length adjustment of the probe.

Control of the weft yarn gathering / from the spool 2 in the shuttle

performed by the probe when the shuttle approaches the forward position.

The weft probe is made in the form of a spring-loaded spring 6 slider 9 with a pointed end 5 interacting with the yarn / or with the body of spool 2. In the slider 9, axially located tentacles 5 and 4 are rotatably fixed at the ends 10, which interact only with yarn on the spool. The ends of the teeth of the tentacles 10 are installed along the cone of a bare spool with a gap, depending on the number of the yarn, by means of a threaded connection of the rods 11 with the tentacles fixed by nuts 12.

FIG. 3 shows the design of the length-adjustable by means of the eccentric 13 of the pointed end 14 of the slider 9, which works in conjunction with the length-adjustable tentacles 5 and.

Tentacles 3 vi 4 are kinematically connected to each other by means of a spring-loaded spring 15, rod 16 with grooves 17, which include processes / 5 tentacles.

The setting of the force of the prul inrs 6 to 15 is carried out by a nut 19 screwed into the body of the probe 20.

The tentacle 3 has a process 21, which is included in the hole of the body of the probe 20, in order to avoid the arbitrary rotation of the slider 9 in the body.

With the spool retracted from the probe, the slider moves forward under the action of the spring 6, the head 22 of the tentacle rod is retained by the nut 19, as a result of which both tentacles are tightly pressed to the tip of the slider. When the spool is pulled over the probe, the engine displaces and the springs compress, the head 22 of the rod moves away from the nut, the tentacles under the influence of the spring 15 tend to move away from the tips of the engine if the yarn winding layer does not hold them, as shown in FIG. 2. The process of the tentacle 21 becomes pa the path of the lever 23 of the automatic stopping device of the machine and with further movement of the slider moves the lever 23, which causes the machine to stop.

With closed tentacles, the process 21 does not touch the lever 23.

Subject invention

Weft gauge for weaving machines, characterized in that in order to be able to work on bobbins with standby winding and without it, it is wise in a type of spring-loaded slider 9, pointed end 5 interacting with a yarn or with a bobbin body and carrying a rotary axle x 7-8 diametrically placed, adjustable in length and spring-loaded tentacles 3 to 4, in contact with their teeth only with the yarn on the bobbin and diverging in opposite directions when the specified yarn layer is reached, for steering through the kinematic transmission stroystvam automatic machine shutdown.
