SU70094A1 - Weft probe for automatic weaving machines - Google Patents

Description

The subject of the invention is a weft gauge for automatic weaving machines. Existing designs of the weft probe for reserve-free winding of the yarn on the shank have drawbacks that cause breaking and damage of the yarn from the spring, the force of which must overcome the force of the opposing spring: thrust levers and friction in the transmission links of the mechanism; zhi from shpuly, having various cones and density of winding.

The proposed design of the weft gauge makes it possible to eliminate the noted drawbacks and differs from the known ones in that the spring-loaded gauge mounted on a movable adjusting eccentric is equipped with a tail process with a pinch at the end, which is inserted into the groove formed by the wall of the gauge body and the adjustable plate when the cob is turned.

FIG. 1 is a front view of the weft probe, and FIG. 2 - view. weft probe at the side.

In the test probe 5 and the movable probe 4, which are pressed against the bobbin 3 by the spring 6, by rotating the adjusting eccentric 10 fixed by screw //, the dependent movement of the tip of the test probe above the teeth of the movable probe is established. The transfer bar / with its ring rests in the body 2 of the probe, at the same time the end of the bar does not reach half of the way from the movable feeler, making it possible for the latter to make a free move to the end of the rod. On the opposite shoulder of the movable feeler, the caudal process 7 is reinforced with a pinch at the end, and on the probe body in the milled groove with a screw 9 a reset plate 8 is screwed.

At that moment, when one layer of weft yarn remains on the splitter, the movable feeler moves freely to the end of the bar /, and the opposite shoulder, as shown in the figure by the dotted line, deviates right

In this amount, which ensures the entry of the caudal process 7 under the adjustable plate 8. With the further movement of the caudal process, the movable plate forcibly rejects the movable feeler and, consequently, the transfer rod with the stop lever. In this case, the latter will fit under the stubborn nest of the sword, which, when moving the shnagi through the transmission links of the mechanisms, will cause the spool to change in the shuttle.

Subject invention

The weft pin, for automatic weaving machines, characterized in that the spring-loaded probe 4, which is rotatably mounted on a movable adjusting eccentric, is equipped with a tail process 7 with a spike at the end, which is inserted into the groove formed by the wall of the probe body and the rearranged blade 8 when the cob is worked.
