Description

The invention relates to consumer goods and relates to devices intended for the orderly layout of the yarns, for example, when rewinding yarn from skeins into balls.

The purpose of the invention is to increase the reliability of the device.

FIG. 1 shows the device, a general view; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a view B in FIG. 2

The coil winding device comprises a housing 1. in which is placed the leading gear wheel 2 of the gearbox connected to the drive handle 3 and gear wheels 4 and 5. The ratio of the diameter-dividing circles of the cylindrical gear wheels is also within the range from 1.04 to 1.2, for example, by making the gear wheel 4c 16 teeth and a gear wheel 5 with teeth. The gear 4 is made on the cylindrical part of the coil holder of the take-up coil 6, which is mounted rotatably about axis 7, which is rigidly fixed in the housing 1. For initial fixing on the receiving coil 6 of the end of the filamentous yarn material 8 to the conical part of the holder, there is a ring 9. Toothed the wheel 5 is mounted rotatably with respect to axis 1, which is rigidly fixed in the housing 1. At one end of the axis 10 there is a yarn thread guide 11 installed for movably securing the yarn section 8. To the gear wheel 5 by means of a threaded nut 12- attached L-shaped rods 13, made of elastic wire. The ends of the L-shaped rods are installed in the holes 14, which are released in the direction of the ring 15 on the axis of its symmetry and form a hinged connection with it.

Sectors 16 are rigidly fixed on the nite-laying ring 15, the ends of which have teeth 17 alternating with depressions 18. Teeth 17 and depressions 18 are made on sectors 16 with a shift of 1/2 step relative to the teeth and depressions of the opposite sector and interact with the periphery G- shaped rods 13. Shifting teeth provides the ability to adjust the angular polo

the direction of the guide ring 15 with a small angle resolution. To secure the device to the working surface, it is provided with a clamping screw 19, which is installed in the threaded hole of the housing 1.

Device for winding filamentary material works as follows.

In the initial position, the housing 1 is fastened to the working surface with a clamping screw 19. The end of the yarn 8 is inserted into the looper thread 11 and fixed to the receiving coil 6 by winding under the ring 9, after which the end of the yarn is firmly fixed on the coil due to the linear displacement ring 9 in the direction of the larger diameter of the conical part of the receiving coil 6,

When the drive handle 3 is rotated, the driving gear 2 drives the gears 4 and 5 with the structural elements fixed to them. The yarn 8 is wound onto the receiving coil 6. When this happens, by interacting the yarn with the ring 15, it is arranged in an orderly manner on the receiving coil 6 with a pitch provided by a fixed angle of the ring 15 relative to the axis of rotation of the gear wheel 5, and due to the difference in the diameters of the pitch circles of the gears 4 and 5 are with the number of yarn threads per diameter of the pickup coil from 5 to 25, depending on the ratio of the pitch circles of the gears 4 and 5 chosen for this design.

As a result of winding on the receiving coil 6, a coil of cross wound yarn 8j is formed, which can be easily removed from the receiving coil by shifting the ring 9 in the direction of the smaller diameter of the conical part of the coil.

When yarns of various thicknesses are used, or when several yarns are wound into one skein to ensure a yarn is formed with the desired ratios of diameter and length, the angle of inclination of the ring 15 is changed accordingly by turning it in the hinge joint. The teeth 17 and the recesses 18 of the sectors 16, interacting with the periphery of the rods 13, provide at the same time

fixing the angular position of the ring 15.

This design of a yarn-winding device has a number of advantages over the known ones. The kinematic scheme of the proposed device is simpler known, as it includes only three gears with a certain ratio of the diameters of the pitch circles, which eliminates a frictional pair from the gearbox winding and reliability of the device during long-term operation. The rotating parts of the device are dynamically balanced and, during operation, the vibration of both the device itself and the individual elements of its construction is eliminated, which ensures ease of operation and increases reliability of operation. In addition, it provides ease of operation due to the simplicity of changing the angle of inclination of the working element (ring) without using a special tool, ensuring reliable operation of the device even in the case of using yarn with nodal joints, because at the moment of interaction of the node with the working element occurs the radial force of the deformation of the elastic rods of the support element and the radial displacement of the working element, due to

which reduces the likelihood of yarn failure.
