SU25081A1 - Control signaling device to the coco-noctal pelvis - Google Patents

Description

A control signaling device for the coco-noctal pelvis is proposed to simplify the method of controlling the thickness of the twisted slit yarn. All subsequent technological processes of production, such as: torsion, weaving, dyeing and finishing of fabric, depend on the uniformity of the thread. The device consists of a pivotally secured lever, at one end of which an agate roller is mounted, which is pressed by a spring to another roller, mounted on a fixed axis ka. When the thickness of the thread changes, the lever rotates around its axis, which, with a sector mounted on its other end, rotates the gear that sits on the same axis as the arrow, which, when significantly deviated, closes the contact device, indicating a sharp thickening of the thread.

FIG. 1 shows a schematic drawing of the location of the control signal device on the coconotal pelvis; FIG. 2 - external appearance of the device; FIG. 3 - its vertical section; FIG. 4 is a side view of it in vertical section.

This fixture is placed in the path of the silk thread from the coconutal pelvis to the reel (Fig. 1), on which the thread is wound so that it is all

the time was between two rotating agate rollers 5 and 54 One of the rollers 5, provided with a circular groove for the passage of silk, thread and pressed by the action of the spring 3 to the pair roller 5, is attached to one end of the pivotally reinforced lever 1, at the other end of which sector 2 is fixed, serving when changing the thickness of the thread to rotate gear 6. Roller 5 has only a rotational motion and is fixed on a fixed axis (Fig. 3). Gear 6 sits on the same axis with an arrow 7 designed to indicate dial 8 (FIG. 2) of the magnitude of the deviation of the NIII diameter from the normal one. The divisions on the dial 8 are applied so that they meet the limit of legal fluctuations of the thickness of the thread according to denier, and in case of going beyond the specified diameter of the thread ,, arrow 7 meets a contact device signaling a sharp change in the thickness of the thread and closing contact of the electrical circuit, as a result of which the reel stops.

The subject matter of the invention.

The control - signal device to the coco-noctal pelvis, consisting of a pivotally reinforced lever, is distinguished by the fact that the lever 1 is equipped with

one end of the roller 5 with a circular groove serving to skip the silk of the 8th thread, pressed by the action of the spring 3 to the paired one, which has only rotational movement, roller 5, and at the other end the sector 2 that serves to change the thread

gear 6, which is located on the same axis as the arrow, is intended to indicate on the dial 8 the values of the deviation of the thread diameter from the normal one and to close the contact of the electrical signal circuit when the thickness of the thread changes abruptly.
