    Method and apparatus for sequentially winding a plurality of windings on a winding form and for transferring the windings sequentially from the winding form to a collecting tool such that the plurality of windings are disposed on a collecting tool for subsequent collection axially through an aperture of a stator sheet packet positioned in adjacency with said collecting tool. In accordance with the invention, during the transition from winding one winding on the form and winding the next winding on the form, the winding wire is held clamped at a point within the peripheral region of the windings disposed on the collecting tool to be drawn through the aperture during subsequent collection. This arrangement offers great simplicity compared to known systems since the forthcoming path of movement of the clamping means is short and simple and because the available relative motion of conventional parts of conventional devices may be utilized to actuate the clamp, thus eliminating the need for a separate drive or control.

    rotation of the spinneret, so that the winding wire cannot be clamped when it is in the tight tensioning state passing from the spinneret to the template. It can be clamped only after the pullers transfer the coils of the wire wound on the template to the device for transferring or pulling the coils into the stator magnetic circuit package. Therefore, there is a risk that the wire cannot be caught by the clamping device, and this can cause damage to the wire during operation. In addition, the known device has a special drive with a control system for the clamping device, which complicates the design of the device. The purpose of the invention is to simplify the design. The goal is achieved by the fact that there are stops on the template and puller, and the clamping jaws are rotatably mounted on the puller, located inside the template and are in contact with the stops. The clamping jaws are equipped with a lever with shoulders in contact with the stops, the shoulders are connected to each other by a spring. In addition, the device contains a hook to grip the wire while changing the direction of rotation of the die, mounted on the template from the outside of the winding area. FIG. 1 a, b shows the positions of the winding pattern in various stages of winding; in Fig. 2 - winding pattern, side view; in fig. 3 a, b, c, d sequence of winding of a four-pole winding consisting of four groups of windings; in fig. i a, b, c, d, d, e are the cross sections of the template zone at different positions of the clamping jaws. The device contains a single or multi-stage sliding template 1, made of two parts, puller 2 movable in axial direction and used to remove the turns of wire 3 wound on the template using a die (. Not shown). In order to prevent sharp bending in the winding wire at the place where the wire is held with the clip installed inside the template 1 by the clamping jaws k and the length of the wire connection between the individual groups of windings on the template 1 is adjusted, a hook 5 is made in the form of a bolt plates, around which when reversing the winding direction, the wire is twisted around in a loop. In the manufacture of two interconnected groups of coils, only one hook 5 is sufficient. When changing direction repeatedly, two hooks 5 are required, which are installed on both sides of the carrier jaws of part 6, which plays the role of a stripper. A device 7 for transferring or retracting coils into the stator package of the magnetic circuit is located under the template. The clamping jaws t are located inside the axial projection of the circle formed by the rods of the device 7. Four full groups of 9-12 coils are located between the rods of the device 7 with the beginning of the 8 wires. i The winding nozzle, when winding different groups of coils, can be in positions 13-17. The clamping jaws C consist of two pivotally connected levers 18 and 19, each of which has a side arm 20 and 21. Between the side arms 20 and 21 there is a spring 22, loading the jaws in the direction of their closing. The levers 18 and 19 are pivoted around the axis 23, with which they are connected to part 6, which can play the role of a puller. In this case, it is rigidly connected with the drive of its reciprocating movement (not shown in the drawing) and can make movements with the frequency of movement of the winding die through the circumference. However, due to the large mass of clamping jaws k on part 6, it is recommended to remove part 6 from the reciprocating movement and only produce a removable movement with a long stroke at the end of winding the hoop coils. Hook Z with stop 25 is pivotally mounted on part 6, loaded with spring 26 in direction of clamping jaws and serves to hold jaws in neutral (Position in the slot of template 1. On template 1, stops 27 and 28 are made, and on lever 19, stop 29. The device works as follows: The first group of 9 coils ((t) and Za) is wound in a clockwise direction, and the winding process is started at a small step of pattern 1. After winding a predetermined number of turns at all steps of the pattern, the winding filler stops in position and hook 5 intercepts the wire directed to the die, at the same time, by moving downwards, the clamping jaws k are moved or moved from the position drawn in the pattern outwards to the level of the winding die, and the jaws of the clamping jaws are opened. clockwise to position 1 the wire is placed around the hook into the jaws of the clamping jaws, (Fig. 1a and Za). In the next working stage, the turns of the wire of the coil group 9 move by moving downwards the pullers 2 and 6 into the gaps between y rods at sposobleni 7. During this motion audio pickups are closed jaws A, exactly holding the winding wire. In this case, the clamping point is located inside a circle formed by the rods of the device 7, i.e. inside the coil group. During the removal process, the wire is pulled out of the hook 5. After removing all turns of coil group 9 and moving them out of the zone of fixture 7, the latter turns 9R ° clockwise. After removing the coil group, pattern 1, puller 2 and part return to the initial position, in which the coils of the wire are placed on the small template step when the die is rotating, while the clamping jaws k remain closed. When producing a four-pole winding, the next group of coils 10 is wound without breaking the wire against the clock As the clamping jaws k are still closed when the winding die is rotated, a wire loop (Fig. 3a) between clamping jaws 4 and a hook is obtained. The loop connects two coils groups 9 and 10. After winding several turns of wire (turns) onto a small one The template stage opens the jaws of the clamping jaws A, since the turns of the wire on the template can absorb the tension of the wire. After the opening of the jaws of the clamping jaws, the pullers move in short strokes with the spinner's rotation frequency and take off most of the turns downward. forward fixture rods 7 during the winding process. However, at each stage of the pattern there remain several turns, which are moved to the device 7 - during the long run of the pullers 2. After obtaining a given number of turns in the coil group 10, the winding die is in front of the pattern in position 15. ZBL After the template is lowered, the other hook 5 covers the wire directed to the winding die and forms a free wire loop during the subsequent reverse movement of the winding die half a turn in a clockwise direction when the wire is again placed in the open mouth of the clamping jaws k. Now, the winding die is in position 16 and retains it during the subsequent process of removing coils of coil group 10 from pattern 1. Then, turning the tool is turned on, and coil groups 9 and 10 are shifted to FIG. Sound Thereafter, similarly to the coil group 9, the coil group 11 is wound, and after switching the pitch of the device 7, the fourth group of 12 coils is wound in the same direction as the group 10. At the end of the winding, the filler stops at position 17 and the wire end is cut off. The length of the loop between the clamping jaws 4 and the hook 5 can be changed by securing the hooks at different distances from the clamping jaws (Fig. 1a, b). When the winding die is started up, the loop is released without a sharp break in the wire. If the coil groups are wound in one direction, then the need to stop the hooks is no longer necessary, since in this case the distance between the coil groups around the circumference is usually of the same size as the circumferential zone occupied by each group. In addition, it is possible to change the length of the switching connection between the groups of coils due to the extension of the clamping jaws during the closing period of the pharynx by a certain distance from the pattern 1 or due to the distance from the front edge of the puller 2. During the winding, the clamping jaws 4 are in the neutral position in the longitudinal the groove of the template 1, and the winding die makes synchronous axial movements relative to the device 7 in accordance with the movement of long-stroke pullers at the end of the winding of a group of coils, resulting in the constant length of the wire between the clamping jaws and the winding nozzle in the intermediate phases during the removal and transition to the subsequent group of coils without jerking the new start of the nozzle. The pullers 2 and part 6 can pass a short distance between the rods of the device 7, regardless of how much the template is immersed in the process of winding into the device 7. The depth of penetration of the template 1 into the device 7 can be 5-15 mm. The remaining turns of the wire 3 located on the template are removed when the pullers 2 are in the lowest axial position, and the template 1 is removed from its busy position of the lowest position up through the front edge of the pullers 2. Thus, axial lengths are saved and paths both on the sides of the template and on the sides of the device 7. During the winding process, the hook 2 holds the clamping jaws in a neutral position in the axial groove of the template 1. At the end of the winding process, when the winding wire going to the filler must be clamping jaws, the template 10 is lowered relative to part 6 so that the stop 27 first presses the rear ends of the two levers 18 and 19 (Fig. 46), causing the jaws of the jaws 4 to deflect outward around the circumference of the template 1 (Fig.). the interaction of the stop 27 with the ends of the levers 18 and 19 of the jaws 4 the ends of the levers are rounded. By the beginning of the rejection of the hook fixation levers, 2k is removed, since the stop 27 first interacts with the lever 19 of the clamping jaws, the side arm of which 21 is not fixed by the hook. The initial rotation of the lever 19 (Fig, b) ensures the interaction of the side arm 21 with the stop 25 of the hook 2, as a result of which it is pressed and releases the fixed side shoulder 20 of the arm 18. In the end position, the stop 27 (Fig. 4B is located between the rear end of the lever 19 and the side strap 20 in such a way that the jaws of the clamping jaws t open under the influence of the spring 22. In this position, the winding wire 78 can be laid into the open jaws of the clamping jaws 4. The wire is below the front edge of the puller 2 and part 6 at the level of the plane coil and due to the movement of the die from position 13 to position 14 or from position 15 to position 16. When moving part 6, the levers are released from contact with the stop 27, and under the action of the spring 22 the jaws close and clamp the wire. with an abutment 28 (Fig. k g} and the clamping jaws rotate around the axis 23 to the position shown in Fig. 4e. In this position the jaws hold the wire inside the circle of the smallest step of the template. In this position, the jaws remain until the end of the removal of turns and in the process of the return stroke of the pullers 2 and part 6 relative to the template 1 until the beginning of the winding process on a small step of the template. Thus, the clamping jaws C hold the wire at the time of the start of the die when winding it onto a smaller step of the template. In order to move a large part of the coils into the device 7 from a small step of the pattern during the winding process, the jaws must release the wire as soon as a sufficient number of turns are wound at a small step of the pattern. To do this, after several turns of the die, the template moves downwards and the stop 28 rotates the lever 19-counterclockwise through the stop 29, and the lever 18 is held in a fixed position by a hook 2k, which engages with its side arm 20. The jaws open (Fig. .e) The clamping jaws remain open until the stop 28, located in the zone of the small stage of the template, comes into contact with the stop 29. With further axial movement of the template to the pullers 2 and part 6 during the winding of the largest stage of the template, the jaws k move into The position shown in FIG. ka. The proposed solution provides short inter-pole connections using a simple clamping device that does not require a special controlled drive and works with high reliability. invention 1.
