SU1528712A1 - Arrangement for continuous winding of thread-like filament material - Google Patents

Abstract

The invention relates to the production of chemical fibers and is aimed at improving the reliability of operation. Each bobbin holder 17 mounted on a turret has a conical friction disc. The conical accelerating roller 15 is mounted coaxially with the turret head with the possibility of simultaneous contact with the disks of both bobbin holders. Shaft 9 is kinematically coupled to an accelerating motor. When the shaft 9 rotates, the hub 11 of the overrunning clutch under the action of inertial forces moves in the axial direction and brings the conical accelerating roller 15 fixed on the cage 13 of the overrunning clutch into contact with the disks of the 16 bobbin holders. When the booster motor is disconnected, the torque is transmitted to the overrunning clutch from the discs 16, which leads to the reverse movement of the clutch and the contact of the discs with the roller 15 is broken, this contributes to the spring 19. 2 sludge.

The invention relates to the production of chemical fibers and is intended for winding the bonded yarn with automatic re-threading of the filament material from the working bobben holder to the reserve one.

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

Fig, 1 shows the device, the overall appearance, in Fig.2 - node I in Fig.1.

The device consists of a shield 1, on which are mounted in the housing 2 on bearings 3 revolving head with a drive 5, a friction roller 6 and a folder with a drive and means 7 for the inlet. An electric motor 8 with an increased slip and a shaft 9 with screw thread 10 are fastened to the housing 2. A hub 11 is mounted on the shaft 9 with an internal screw thread 12, which together with the yoke 13 of the freewheel 1 is displaced along the shaft axis 9. The sleeve 13 of the coupling has The end of the conical acceleration friction roller 15, which has the possibility of contacting with the response friction discs 1b attached to the ends of the bobbin holders 17. The bobbin holders are provided with means 18 for automatically refilling the thread of any known construction.

To remove 15 from engagement with the discs 16 on the shaft 9. A spring 19 is installed, abutting at one end through the bearing 20 into the sleeve 1 and the other into the thrust washer 21, which simultaneously serves to adjust the force of the springs 22. The device works as follows .

In the initial position, i.e. during winding of the upper (working) bobbin holder, roller 15 of the overrunning clutch is pressed by spring 19 from disks 1b. Upon completion of winding, a signal is sent to the means for removing the friction roller 6 from the package, to the drive 5 of the turret rotation k, to the drive 8 of the accelerating roller. Shaft 9 begins to rotate. The hub 11 under the action of inertia moves along the screw thread 10 and 12, compressing the spring 19, before the acceleration roller 15 engages with the discs 1b. When the turret is rotated, the thread is wound on the upper package, which is driven by the disk 1b, and the automatic re-filler means 18 with

It also performs a rotational movement together with an empty cartridge on the backup (bottom) bobbin holder. The revolving head 4 is rotated 180 and fixed, the thread is refilled to an empty cartridge in a known manner. A signal is applied to the feed of the friction roller 6 to the chuck. At the end of the package formation and during rotation of the turret C, the angular speeds of both bobbin holders 17 are the same and correspond to the linear winding speed. At the moment of contact of the friction roller 6 with a cartridge on which a new package begins to form, the angular velocity of the disk 1b of the bobbin holder, and hence of the roller 15, increases sharply (the diameter of the cartridge is less than the diameter of the package), the clip 13 of the freewheel I disengages from the hub 11 and rotates independently of the rotation I of the shaft 9 of the electric motor 8. A signal is given to turn off the drive B of the acceleration switch. The spring 19 removes the disk 15 with the disks 1b from the screw thread 10 and 12 from chilling.

The presence of one accelerating roller and the use as a means of supplying and withdrawing the roller to the disks of the bobbin holders of the overrunning clutch with screw thread greatly simplifies the design. Tests of the proposed device showed high reliability in a wide range of operating speeds.
