Description

I 1

The invention relates to methods for winding a lengthy material, for example, for winding an apas wire onto a flexible spool when preparing ring coils with an oroidal core on special machines, for making guitar and piano strings and similar products and can be used in radio engineering and electrical engineering. , instrument-making, electronic industry and other. .

A known method of winding a long material, implemented in the shuttle machine for single winding of a winding on core barrels (strings), consists in rotating around the frame of the coil (spool) and simultaneously moving the frame along its axis to obtain the necessary winding pitch t1.

The closest to the invention is the method of an endless open-loop winding realized, for example, in a single-spindle machine for one-side winding, consisting in rotating the winding frame (base) around its axis and the direction of the winding material and moving along the frame axis (base) around its axis and layout mechanism L23.

A disadvantage of the known methods is the complexity of their implementation due to the fact that to obtain the necessary spacing of the layout, it is necessary to move the point from which the winding material is directed along the frame axis in synchrony with the rotation of the winding frame.

The purpose of the invention is to simplify the winding process,.

The goal is achieved in that according to the method of winding a lengthy material on a flexible base by directing a lengthy material onto the base and rotating the base, the long material is directed from a fixed point or tangentially to a fixed curve, and before the base rotates it is bent.

A device for winding a lengthy material onto a flexible base, comprising a base fixing mechanism associated with a rotating drive, and a length guiding element 561032

numbered material, provided with guiding elements made along an arc with a cavity for accommodating the base and a slot along the cavity 5 for placing a lengthy material on the base, and an element for guiding a lengthy material, such as a roller, is fixed coaxially with the guiding elements.

10 In addition, the device is provided with stops installed at each end of the guide elements.

FIG. 1 shows the scheme for the proposed method; in fig. 2 through 5, the relative positioning of the nodes in the device for implementing the method, in FIG. 3 shows section A-A in FIG. 2; in fig. 4 shows a device with another actuating element for guiding the long material in FIG. 5 shows a section B-B in FIG. four.

According to the method, the flexible base 1 (Fig. 1) is bent and rotated around its curved axis (shown by an arrow), and the material of the winding 2 is directed along a tangent to a fixed curve 3 or from a fixed point. In this case, when winding, the required angle (changing from 30 s according to a given law or constant) is provided between the normal to the axis of the base and the direction of the winding material. The device (Fig. 2) for carrying out the method includes a mechanism 4 for sticking the base, associated with a rotating drive, guiding elements 5 and 6, made in an arc with a cavity 7 and a groove 8. A flexible base 1 is placed in cavity 7 formed on. the guiding elements 5 and 6. In the center of the arc formed by the cavity, there is an element for guiding the material of the winding 2. In this case, this element is designed as a roller 9 mounted coaxially with the guiding elements. The material of the winding 2 is filled through the roller 9 and the groove 8, formed by the guiding elements 5 and 6, and is attached with its end to the flexible base 1. The element for guiding the material of the winding can be made as a sleeve 10 with a hole whose axis coincides with the center of the arc and perpendicular to the arc plane. The edges of the holes are rounded. Supports 11 and 12 are installed near the cavity.

The device works as follows.

The mechanism 4 rotates the flexible base 1 around its curved axis, while the guiding elements 5 and 6 ensure that the position of the curved axis of the base in space does not change. The material of the winding 2 is placed on the base 1 at a given angle cL, depending on the diameter of the roller 9. If the winding should be made to turn to a turn, then the angle di can. be equal to 0. In this case, the winding material is tucked through the opening of the sleeve 10. Angle d is related to the layout step t by the following relationship:

oСqrct

IT (D + b)

where D is the diameter of the base

B is the diameter of the material being wound.

The distance from the flexible base to the point of contact of the winding material with a fixed curve depends on the required layout step and on the selected bending radius of the base, so with a uniform step this distance is

S-R-cosd-.

Under the action of tension, the material of the winding 2 is laid on the base 1 turn to the turn. At the end of the winding of the first layer, the material of the winding 2, interacting with the stop 11, changes the direction of winding to the opposite and the second layer is wound up after the interaction of the material of the winding 2 with the stop 11, the third layer is wound, etc.
