Abstract

The invention relates to the winding of a thread-like material and is aimed at simplifying the design and reducing the dimensions of the thread folding machine. The thread stacker contains a slider 6 placed in the screw groove of the drum 2. Cracker 4 is installed in the translational guides 3 and hinged on the axis of the slider. On axis 15 of the cracker, the lever 13 is pivotally fixed, on one shoulder of which a yarn feeder is mounted, and the second shoulder is connected to axis 16 with a ratchet wheel 7 freely mounted on axis 5 of the slider. Khrapov doggie is rigidly fixed on the axis of the slider. For each double stroke of the slider, the ratchet wheel, interacting with the dog, turns on one tooth and moves the lever with the yarn guide. The result is the dispersion of the turns of the folding filament material at the points of the reverse. The design of the folder stacker is simple and compact. 2 Il.

The invention relates to the winding of a thread-like material on scaffolds such as bobbins, coils, spools, and concerns the design of the thread-folding mechanism of the wind mechanism.

The purpose of the invention is to simplify the design and reduce the size.

Figure 1 shows the folder, a cross-section; figure 2 is the same, top view.

The thread spreader consists of a housing 1 in which a screw drum 2 is installed, which is connected to a rotating drive. On the housing 1 there are fitted guide plates 3 with a cracker C, on which a slider 6 is mounted by means of axis 5. The slider is rigidly fixed at the end of the axis and placed in the groove of the screw drum. On the axis 5 of the slider 6, the ratchet wheel 7, enclosed by the lid 8, is freely mounted, and the ratchet dog 9 with spring hooks 10 is rigidly seated. The ratchet wheel 7 on the inner surface has a certain number of teeth and an equal number of radial holes, located in the hollows of the working profile. ratchet wheel. The push-rods 11 are freely placed in the holes. On the cracker k there is a locking mechanism 12 made in the form of a spring-loaded pin, and a lever 13 with a thread lA on the axis 15. The second lever arm 13 through the axis 16 is connected with a cover 8 ratchet wheel 7. The axis 16 can be fixed at any point of the groove 17 on the cover 8. The cover 8 has

but smaller diameter that fixes the rods 11 in the ratchet wheel 7. The pin axis of the locking device 12 lies in the plane of the axes of the radial holes of the ratchet wheel 7 and the cover 8. And the tyr has the ability to spring into the radial holes of the cover 8.

Dog 9 has two. an elastic hook 10, made in the form of a two-arm lever for balancing reaction forces on the axis 5 of the slider 6, which increases reliability and improves the conditions of its operation.

Folder works as follows.

During the rotation of the screw drum 2, the cracker, together with the slider 6, reciprocates along the guides 3, laying out the thread passing through the thread guide I.

With the passage of the reverse section of the screw drum 2, the slider 6 is rotated by a certain angle equal to the angle between the axes of two adjacent radial holes. As a result, the dog 9 spring hooks 10 acts on the ratchet wheel 7 and turns it and the cover 8 at the same angle. The cover 8 through the axis 1b acts on the lever 13, which rotates around the axis 15 at a certain angle, thereby displacing the layout of the thread in the package. At the end of rotation, the pin of the locking device 12 enters the adjacent radial opening of the cover 8 and fixes it together with the wheel 7.

When passing the opposite reversing portion of the screw drum 2, the slider 6 rotates at the same angle, but in the opposite direction. In the process of turning the slider 6, the spring hooks 10 of the pawl 9 are transferred to the adjacent tooth of the ratchet wheel 7 and come into contact with the rods 11 located in the corresponding apertures. One of the rods 11 leads the pin of the locking device 12 out of the radial opening of the cover. The device is set in the initial position, which is maintained in the interval of movement of the slider 6 between the reverse sections of the screw drum 2 until the next cycle.

At the same time, the period of the displacement of the thread on the package is equal to the time during which the needle spreader performs a number of double strokes equal to the number of teeth of the ratchet wheel 7.

The size of the scattering section of the yarn on the package can be set by changing the axial distance between axes 5 and 1b by installing axis 1b in the slot 17. I

The thread spreader provides high-quality winding by scattering the layout of the thread in reversible areas, has small dimensions and is simple in design. The selection of the design parameters of the handler allows optimization of the winding process for a wide range of thread-feeding materials.
