Abstract

Use: for rewinding textile yarns, as well as flexible wires in the textile and electrical industries. The essence of the invention. the machine contains two retractable coils on the drive holder, a spring-loaded lever yarn for sequentially placing the thread-like material on the coils, associated with a cam mounted on the camshaft, a material cut-off unit and a feeder coil with a drive cutter. The coil holder includes shafts according to the number of coils driven by the axial movement of each of them. The coils are mounted on the shafts of the cantilever, and the camshaft is equipped with additional cams for driving the splitter, cutting tools and shafts of the coils. 3 il.

WITH

The invention relates to machines for rewinding filamentary material and can be used in the textile and electrical industries.

A device for winding a thread-like material containing two coaxial-driven drive nipoles, a needle spreader with extreme and middle position sensors, a means for re-threading the thread-like material on the spools, an arc-shaped yarn feeder is known.

A device is known comprising two axial coils rotatably mounted on the drive holder, a spring-loaded lever yarn feeder for sequentially placing the filament material on the coils associated with a cam mounted on the camshaft and means for cutting the filamentary material.

A disadvantage of the known device for winding filamentary material is the low productivity of the device, the complexity of the design of the means for refilling the filament material and the yarn feeder.

The purpose of the invention is to improve the performance of continuous winding of filament material on the coils.

The goal is achieved in that the device for continuous winding of threads contains a feeder of bobbins with a drive shut-off device, and the holder contains shafts according to the number of spools with axial movement of each of them, and on the camshaft there are cams to drive the shut-off device, means for trimming and shafts of coils.

The continuous winding machine of the thread-like material consists of the body 1, in which there is an axis 2 rotatably and rigidly attached holders 3, 4 containing drive wheels 5.

The shafts 6 having grip with the drive wheels 5 have the possibility of longitudinal movement relative to the wheels 5 to a height equal to the width of the frames of the coils 7 coaxially arranged on the shafts 6. Longitudinal movement of the shafts 6 of the holders 3 and 4 occurs under the action of the driving mechanisms 8. The guide 9 represents is a spring-loaded swinging lever 10 with a cam disc 11. The knife 12 is a spring-loaded lever 13 with a cam 14. The spring-loaded cutter 15 of the feeder 16 can be moved along the pressure of the cam disc 17 is the guide 18 and tray 19, the accumulator 20 moves along direction L of the guide 18 under the action of cam plate 21. The driving wheel 5 through a belt transmission 22 has a connection to the clutch motor 23, the shaft 2 receives a rotation through a worm mechanism of the motor. (The electric motor and the worm gear are not shown in the drawing).

Machine for continuous winding works as follows.

From the electric motor (electric motor not shown) through the worm gear the axis 2 is rotated with cam discs fixed on it, from the same electric motor via belt drives 22 the driving wheels 5 are rotated which have a clutch (see Fig. 3) with shafts b holders 3 and 4. As soon as one of the coils 7 is filled with threads of the yarn, the yarn guide 9 transfers the thread to the other, located next to it, the coil 7 rotating synchronously with the coil already filled with coils (i.e. when the cam disc 11 rotates nny lever 10 oscillates with a small amplitude: lays yarn on the spool and carries a thread with a full reel to an empty, i.e., the yarn guide is a means for refilling the coils 7). After some time after transferring the thread to empty

the coil 7 (the time for threading the thread on it) is triggered by the knife 12: the thread between the coils is cut, the cam mechanism 8 is triggered as a result of which the shaft 6 moves to

the longitudinal direction and leaves the coil 7, filled with filamentous material, and under the action of gravity force, it falls into the accumulator 20. Then the mechanism works in the following order: (this

provided by the shape of the cam discs on the axis 2) the pallet 18 enters under the feeder 16, then the cutter 15 leaves the feeder 16 and the reel from the feeder 16 is empty onto the pallet 18, the cutter 15 returns to

the initial position of the coil retainer in the feeder 16, the drive mechanism 8 moves the shaft 6 towards the coil 7 located in the pan 18 and the shaft 6 enters the coil, the pan 18 returns back to its original position. Thus, that length of time while the filamentous material is wound on one coil 7 (for example, on holder 3) on holder 4, there is a change of coils: full falls into the drive

20, empty from the feeder 16 takes its place. Thread guide refills coils on holders 3 and 4.
