(54) MACHINE FOR winding ball products

one

The invention relates to a machine tool industry, in particular to the design of machine tools for winding ball products with composite or other long materials.

A known machine for yamotki ball products, containing the holder of a mandrel with a drive, made in the form of two racks mounted on the base in guides with the possibility of changing the distance between them, and the layout device with a guide roller, having the possibility of reciprocating circular motion relative to the axis, perpendicular axis of rotation of the base of the holder, and reciprocating motion relative to the mandrel. This machine provides rigid fastening of the mandrel for two polar fittings 1.

However, when layers with corners of patterns less than 45 ° are wound on this stack, the movement having the highest speed is a reciprocating-circular motion, which limits the productivity of the machine.

The closest to the proposed design and the problem to be solved is a machine for winding ball products, containing a cantilever holder of a mandrel mounted horizontally with the possibility of turning along profiled guides around a vertical axis passing through the axis of the mandrel and expanding heads with their drive rotation around mandrel 2.

The disadvantage of the known machine is that tape winding is difficult in it, when being fed from a stationary source, it is possible to assemble into a bundle, since the source does not have a synchronous rotation with the stacker. This significantly reduces the productivity of the machine. Another disadvantage of the known machine is

15 that, using the wet winding method, it is constantly doused with excess binder, creating an increased environmental hazard, and polymerization of this binder at the machine nodes, including the guides, creates complexity

° its service. In addition, the folding heads in a known flock are subjected to uneven deformation of the material being wound, which negatively affects the quality of the winding.

The aim of the invention is to improve the performance and quality of the winding.

To achieve this goal in a machine for winding ball products, a cantilever holder of a mandrel mounted rotatably around its axis and rotatably along shaped guides around an axis passing through the axis of the mandrel and folding heads with a drive of their rotation around mandrels, the mandrel holder has a drive of reciprocating longitudinal movement, and the folding heads are equipped with mechanisms for displacing and rotating them relative to a plane perpendicular to the axis of rotation GOVERNMENTAL heads and extending through the pivot axis of the profiled rails.

FIG. 1 shows the basic scheme of a machine for winding ball products; in fig. 2 - kinematic layout of the folding head; in fig. 3 shows an embodiment of a folding head; in fig. 4 is a schematic of a machine for winding ball-like products when winding a layer from two heads.

On the frame 1 in the bearings 2 mounted hollow shaft 3, which is fixed pick-up device 4, through a gear 5 connected to the drive 6.

On the folding device 4, folding heads 7 are mounted, which are connected via a collector 8 with a source of electrical energy to ensure heating of the folding rollers 9.

The ball holder 10 is fastened to the holder 11 by means of a threaded connection and secured with a lock nut 12. The free end of the holder 11 is made in the form of a spline shaft 13 connected via a gearbox 14 to the actuator 15. The mounting of the mandrel 10 to the holder 11 can be done by any other known means. The holder 11 is mounted in quill bearings 16, freely mounted in the sleeve 17. The sleeve 17 is rigidly fixed to the housing 18, and the quill 16 through the gearbox 19 is kinematically connected to the actuator 20.

The quill 16 with the gearbox 19 and the actuator 20 is a reciprocating longitudinal stirring mechanism of the holder 11, which can be controlled manually or according to a program. A quill 16 has a scale for visually controlling the amount of movement. The housing 18 through the gearbox 21, having its own actuator 22, is connected to the profiled guides 23, along which the housing 18 together with the holder 11 can rotate around an axis passing through the center of the coordinate axes, and perpendicular to the axis II of rotation And and axis II-II of the rotation shaft 3.

FIG. 1 point O - the center of the coordinate axes coincides with the geometric center O, the ball mandrel 10, and the axes and II-II also coincide, which is most clearly shown in FIG. four.

The tape winding material is indicated by the position 24. The folding heads 7 placed on the folding device 4 include the rollers 9, the rollers 25 and the system of rollers of the ribbon path (not shown in the drawings). The folding heads 7 are connected to the folding device 5 by means of a mechanism for displacing and turning the heads 7 relative to the plane A-A, perpendicular to the axis of rotation of the spreading machine.

The mechanism for displacing and turning the folding heads 7 includes a platform 26, 5, an axis 27 with a lock of an adjustable angle of rotation 28, a chamber 29 with a screw adjuster of position 30 located on the guides 31.

FIG. 1 and 4 turn the mandrel product

 is indicated by arrows X (X coordinate), rotation of the rotary pickup device - by arrows Y (coordinate Y),. the axis of the mandrel is rotated by the holder's drive about the profiled direction - by arrows Z (Z coordinate), the axis of rotation of the spreader 4 (or shaft 3) is indicated II-II, the axis of rotation of the holder with the mandrel - II, the adjustment displacement of the heads 7 - by arrows B, the tuning turn of the heads 7 - by the arrows y, the direction of the longitudinal movement of the mandrel - by arrows B, the winding angle - l. The machine works as follows. When winding onto the mandrel 10 layers with a pattern at an angle ot (see Fig. 4), the housing 18 is driven by the drive 22 along the profiled guides 23 so that the smallest angle between the plane A-A of rotation of the folding heads and the axis II of rotation of the mandrel 10 would also be equal to l. At the same time, the mandrel 10 is installed with the geometric center Oi relative to the center O of the coordinate axes of the machine (in Figs. 1 and 4) the points O and O) coincide) with the help of the actuator 20 through the gearbox 19 and the quill spines 16 of the carrier 11. The splined shaft 13 of the carrier 11 slides in a splined movable connection with the gearbox 14, allowing this movement to be carried out both with the fixed mandrel 10 and with the rotating one. The rotation onto the shaft 13 is transmitted through the reducer 14 from the actuator 15. The lengthy material 24 that is being fed is fed from 25 (see Figs. 2 and 3) through the ribbon path and the folding rollers 9, which, when rotating the clapper 4, wind the mandrel 10. Rotate the clapper 4 is carried out by the actuator 6 through the gear 5 and the shaft 3. With each revolution of the rotary pickup device 4, the mandrel 10 rotates by the amount required for

displacing the ribbon from a flat turn to obtain a continuous layer. When winding a product with layers of variable angles l. the transition to a layer with a new angle LL is carried out automatically according to the program by turning the housing 18 (axis I-1) to a new angle.

Drives 6, 15 and 22 are controlled by a program from a numerical control device according to the laws defined by the drawings and the sequence of 10 layers wound onto the mandrel. In this case, the main movement (having the highest speed) is the irreversible rotational movement of the spreading machine 4.

For most of the known spherical products, the layer winding program in such a machine can be set in one or two frames. The longitudinal movement of the mandrel 10 from the actuator 20 along the axis can be carried out either programmatically or manually. The amount of movement in the manual mode and according to the program can be controlled by the metric scale located on the quill 16. Such longitudinal movement in some cases is necessary for accurate installation of the mandrel 10 with the geometric center QI in the center O of the coordinate axes of the machine, for example when winding a sphere with the same polar with holes, and in other cases, for example, when a polar hole is necessary for only one connector and full winding of the opposite pole (poles without a choke), for a corresponding offset of the geometric price Tra Oi mandrel 10 from the center of the coordinate axes of the machine, as well as for correcting programs from layer to layer when winding a package of several layers;

B. machine provides the ability to use dvuhhohodnry winding due to the second folding head. In order to realize the continuity of the layer in this case, improve the quality of winding and eliminate uneven deformations of the lengthy material, the opposite displacement (see Fig. 4) of the heads 7 by means of the screw adjusters 30 relative to the plane A-A passing through the point O due to the movement of the carriages 29 along guide rails 31 by values B equal to about 1/2 of the width of the tape. At the same time, the corresponding turn of the heads 7 relative to the plane A-A through the angle Y, corresponding in an arc of the profile of the product, is also of the order of 1/2 of the width of the tape. More precisely, the B and Y values are calculated when the winding program is calculated. The rotation at angle f of the head 7 is carried out by rotating the platform 26 around the axis 27 and is fixed by the latch 28.

The displacement by the value of B and the rotation of the heads by the angle y is carried out by mechanical readjustment of the machine before starting the program.

FIG. 1-4, there are no electro-automatic elements shown that block mutually exclusive situations 5 and fix the required positions using sensors.

The presence of a mechanism for the longitudinal movement of the holder allows in several. reduce the time required to install the product to the geometric center

0 relative to the center of the axes of the machine, for example, the geometric center of the ball to the center of the axes of the machine — when winding a ball with the same polar holes, with a given offset of the geometric center of the product from the center of the axes of the machine — when winding a ball with different polar holes, in the particular case of winding with one of the poles fully open (the most

0 is a typical case of the cantilever version with one nipple), when correcting layers as the thickness of the winding package is set, such a reduction is especially significant when winding a batch of differently sized products. Eliminated previously existing

the need to manufacture miscellaneous tooling for fastening the mandrels of products in holders. The presence of mechanisms for shifting and turning the spreading heads at the machine provides the possibility

to use the formed ways of winding (multithreading). These design changes significantly increase machine productivity.

Transferring the sources of the winding material to the spreadsheet and the execution of the source of the winding material in the form of coils and similar devices allows tape winding, eliminates twisting, strapping and other types of deformation of long material, and turning and shifting the folding heads are fine tuning the machine to reduce the unevenness of the belt tension improves the quality of winding when using the more advanced method of "dry winding (winding

5 long material with dried to a certain extent binder).

Thus, the proposed machine design allows for improved winding performance and quality.
