(54) METHOD OF WINDING THREADED MATERIAL

ON THE FRAME

 72599: 2

The device contains a spindle rotation circuit that turns off the electric motor 1, the V-belt transmission 2, the guitar 3, the spindle4, the mandrel 5 mounted in the spindle 4, the revolution counter b, the stacker displacement circuit containing the electric motor with constant current 7, the gearbox 8, the driving screw 9 interacting with a nut 10, a stacker 11, a resistor 12, the slider of which is rigidly connected to the stacker 11, is fixed to the container. To reverse the rotation of the lead screw 9, the device is equipped with contact groups 13 and 14.

Switching contacts 13 and 14 is done with the help of stops 15, the distance between which can be adjusted depending on the width of the package. Communication between the rotation chain and

spindle and stacking chain Kai is implemented by cam 16 and contact group 17, Filament preparation chain includes coil 18 with material to be wound 19, brake means 20, glue wetting unit 21, tension tool 22.

The winding is carried out from a smaller section thickness a to a greater thickness b (see Fig. 1, c).

During operation, rotation from the electric motor 1 through the V-belt drive 2, the guitar 3 is transmitted to the kapindle 4 and the mandrel 5. From the spindle 4, the rotation is transmitted to the cam 16, which interacts with the contacts 17, while the stacker 7 moves the motor periodically. The rotation of the electric motor 7. The gear reducer 8 is transmitted to the spindle 9. When the spindle 9 rotates, it moves from the nut 10 with the stacker 11 fixed on it. Altering the mandrel 5, the stacker 11 performs stacking of the filament material 19, ... unrolled from the coil 18. Together with

The stacker 11 moves the rheostat 12 engine rigidly connected with it, changing the voltage at the engine 7 inlet, then, in turn, goes to the change in the speed of mixing the stacker 11. As the stacker 11 approaches the greater thickness of the section

see FIG. 1) speed

packages (

it decreases, and the number of coiled layers increases. At the end of the path it will be equal to the calculated one (3-4 layers). After the stacker has traveled a path equal to the width of the package, using the contact groups 14 (or 13) and the stops 15, the rotational direction of the lead screw 9 will change. The nut 10 and the spreader 11 will move in the opposite direction.

According to the m-closer to the smaller thickness of the package section (a,

see FIG. 1) the speed of the stacker increases, and the number of layers decreases to the calculated one.

Thus, by changing the speed of movement of the stacker at a constant rotational speed of the mandrel, a conical package is formed. In this case, if the winding

carried out from a smaller package to a larger one, the speed of the stacker is slowed down (the number of layers to be wound increases); when moving the stacker from a greater thickness of the package to a smaller one, its speed increases, and the number of layers decreases.

Claims (2)

Invention Formula 1, Method of winding filamentary material on the mandrel, in which in one pass of the stacker along the axis of rotation of the mandrel several 5 layers of material, characterized in that, in order to obtain a package of conical shape, the ratio of the rotational speeds of the mandrel and the displacement of the stacker is changed in proportion to the thickness of the package. 2. The method according to Claim 1 is also distinguished by the fact that it changes the speed of movement of the stacker in inverse proportion to the thickness of the package. f 3, a method according to claim 1, characterized in that the rotational speed of the mandrel is changed in direct proportion to the thickness of the package. .
