Description

(54) Return mechanism for driving conductors when winding chemical fibers

The reversing mechanism for driving conductors in the winding of chemical fibers with reduced noise, reduced stress on parts, with reduced space requirements, consists of two discs mounted on opposite ends of the common shaft, where the drive disc is attached to it by two ends and the toothed disc is connected by means of two equally fastened and partially girded toothed bands to a guide rod, which is provided on both sides with a filament guide holder.

It is an object of the present invention to provide a reversing mechanism for driving conductors when winding chemical fibers, which solves noise reduction and stress on parts, as well as deforming the shape of the winding coils of similar devices.

Known devices of this kind, especially for the winding of synthetic fibers, consist of cylindrical drums with guide grooves or curved discs.

When spinning viscose fibers to guide them onto a spool, it is not possible to use complex winding heads, therefore, in the known devices for driving the fiber storage conductors, mainly sliding or lever devices are used.

The construction is complex, very difficult to manufacture and maintain. In these devices, increased inertia forces occur in the return positions, causing increased noise and stress on the components of the device, as well as a gradual increase in the clearance of the entire mechanism. Increasing the dude and inertia forces cause the fiber length in the return positions on the coil to become increasingly large, so that deformed edges of the bobbins are increasingly formed which act adversely for further processing of the wound bobbins, such as rusting, twisting, and winding.

The device according to the invention consists of: two disks mounted on opposite ends of a common shaft, where the upper drive disk is connected by means of two ends of it to the opposite end and only partially abutting flat belts connected to a drive rod on which the other end is mounted; the driven toothed wheel is connected by means of two equally fastened and partially fitting toothed belts to a guide rod, which is provided with a filament holder on both sides, eliminates the disadvantages described above by consisting of a small number of reciprocating parts, thereby reducing inertia forces and their influence on the deformation and shape of the slut, as well as the service life of the components of the mechanism.

According to the invention, the drive movement is transmitted from the drive rod through strips and disks mounted on opposite ends of the common shaft to a guide rod which is provided with a fiber guide holder on both sides.

The attached drawing shows a spatially illustrated example of an embodiment of the invention. At the opposite ends of the common shaft 1, a drive disk 2, on the periphery of which the flat bands 4, 5 and a driven toothed disk 3 on the periphery of which the toothed bands 6, 7 are attached, are fixedly mounted. attached and in the opposite direction only partially flat belts 4, 5 connected to a drive rod 8 on which their other end is attached, the driven toothed disk 3 is connected by means of two equally fastened and partly belted toothed strips 6, 7, to a guide rod 9, which is provided on both sides with a holder 10 with fiber conductors 11.

The reversing mechanism operates as follows: when the machine is started, the drive rod 8 in the drawing is not moved by a linear movement in direction A, not shown, whereby the common shaft 1 with the drive disc 2 starts to rotate under forces in the flat tape 5 The flat tape 4, which is attached in the opposite direction to the flat tape 5 on the drive rod 8 and the drive disc 2, is wound on the drive disc 2.

Since the driven toothed disk 3 and the drive disk 2 are mounted on a common shaft 1, they rotate together. As a result of said rotational movement, the toothed strip 6, which is attached at its ends to the guide rod 9 and the driven toothed wheel 3, exerts a force proportional to the torque on the common shaft 1, driven toothed wheel 3, pulls the guide rod 9 with holder 10 and fiber guides 11. in a straight line in the direction D and being wound onto a driven toothed disk 3. The toothed tape 7, which is attached in the opposite direction to the toothed tape 6 on the guide rod 9, is unwound from the driven toothed wheel 3.

Upon reaching the limit position, the control member not shown in the drawing changes the direction of movement from direction A to direction B, whereby the drive rod 8 begins to move in direction B and the guide rod 9 with the holder 10 and fiber guides 11 in direction C. to the previous description of the function in the opposite direction. This reciprocating movement is constantly repeated.

The reversing mechanism permits the transmission of movement from the drive rod 8 to the guide rod 9, which can be oriented in any direction in a plane perpendicular to the common shaft 1.

The reversing mechanism allows the speed of a linear reciprocating movement to be changed if any of the disks is of a shape other than a round, for example a cam.

The return mechanism can be used for winding any longitudinal materials such as tapes, wires, cables, etc. on the spool or other corrugating organ.
