Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a winding machine in which a wire is wound around a winding former to form a coil using a flyer, and the coil is removed from the winding former using a stripper built into the winding former. This invention relates to a device that prevents rotation.

Conventionally, in a winding machine with a built-in stripper in the winding form, the hollow supporting shaft of the winding form is inserted into the hollow rotating shaft of the flyer and connected to a planetary gear train for closing the winding form. The shaft is inserted into the hollow support shaft of the former and connected to the stripper drive.

However, in this conventional wire winding machine, the rotary shaft of the flyer has a support shaft of the winding form with a built-in sliding shaft of the stripper inserted through it, so the outer diameter becomes large. The diameter of the bearing that supports the fryer's rotating shaft becomes larger. Therefore, considering the permissible speed of the bearing, it is difficult to rotate the rotary shaft of the flyer at high speed, and it is impossible to improve the efficiency of the winding operation. Furthermore, since a planetary gear train is used to prevent rotation of the winding form, the winding form closing device has a complicated structure. An object of the present invention is to provide a winding form sealing device for a winding machine with a simple structure that eliminates the above-mentioned conventional drawbacks and can improve the efficiency of winding work by rotating the flyer at high speed. It is to be.

It is loosely fitted into an arcuate connecting groove 23 formed on the distal end surface. When the winding machine equipped with the winding form rotation stop device of this example is driven in the starting state shown in FIG. 1 and described above, the rotating shaft 3 rotates.
The flyer 8 rotates around the winding forms 19 and 20, which are completely prevented from rotating by the movement member 36, and the wire W pulled out from the outlet of the wire insertion hole 10 at the tip of the flyer arm 9 is connected to the conical surface of the winding form for wire sliding. 21 and 21, and is sequentially wound in a single layer around the tips of the outer peripheral surfaces of the winding forms 19 and 20 to form a single coil. The coil moves through the gap between the outer peripheral surface of the mold 20 and the inner surface of the turning groove 33 of the fixed member to the tip side of the winding former, that is, the side of the coil insertion jig 40, and the leading end of the coil enters the connecting groove 23 of the upper winding former. Several guide shafts 42 of the inserted coil insertion jig
The flyer 8 rotates a set number of times to form the winding forms 19 and 2.
When the wire W is wound around the stripper a set number of times, the rotating shaft 3 of the flyer stops, the pushing shaft 28 moves forward, and the sliding shaft 24 of the stripper moves forward against the helical spring 27, and the flange 16 of the support shaft is moved forward. As shown in FIG. 3, the stripper 25 that had been in contact with the coil moves forward and protrudes from between the upper and lower winding forms 19 and 20, and the stripper 25 that was in contact with the winding forms 19 and 20 moves downward. The outer peripheral surface of the side winding die 20 and the locking groove 33 of the fixing member
The coil is moved to the tip side of both winding forms 19 and 20 through the opening between the inner surfaces of the winding form, and is removed from the ends of both winding forms, and the coil is inserted into the connecting groove 23 of the upper winding form by several pieces of the coil insertion jig. At the same time, as the stripper 25 moves forward, the cylinder devices 34 and 35 operate, and the movable member 36 retreats as shown in FIG. The coil insertion jig 40 is disengaged from the engagement hole 22 and retreated to the rear side of the coil receiving plate 45, and then the coil insertion jig 40 is rotated a quarter turn.
Several guide shafts 42 with coils inserted are removed from the connection groove 23 of the upper winding form, and several guide shafts 42 with no coils inserted are inserted into the connection groove 23 of the upper winding form, and the push shaft Helical spring 27 in which sliding shaft 24 is compressed as 28 retreats
The stripper 25 returns to its retracted end position, and after the coil insertion jig 40 rotates, the cylinder devices 34 and 35 operate to move the movable member 36 forward, and the stripper 25 returns to its retracted end position. The tapered engagement pin 38 of the movable member that has passed through is inserted into the engagement hole 22 of the lower winding form whose rotation is incompletely stopped by the fixed member 31, and the winding forms 19 and 20 are completely rotated again. It stops rotating and returns to the starting state shown in FIG.

Then, the flyer 8 rotates again, and a coil is formed in the same manner and inserted into the guide shaft 42 of the coil insertion jig.
When the four coils are inserted into the guide shaft 42 of the coil insertion jig, the winding process is completed, the sleeve 2 is retracted, and the rotating shaft 3, flyer 8, winding forms 19, 20, etc. are retracted. , the guide shaft 42 of the coil insertion jig comes out of the connection groove 23 of the upper winding form, and the coil insertion jig 40 that has locked the coil is inserted into the winding form 1.
Thereafter, a coil insertion process is started in which the coil latched to the coil insertion jig 40 is inserted into the slot of the stator. Note that even if the sleeve 2 retreats and the winding forms 19 and 20 move back in order to extract the guide shaft 42 of the coil insertion jig from the connection groove 23 of the upper winding form, the tip of the lower winding form 20 remains attached to the fixed member. The winding forms 19 and 20 are loosely fitted into a locking groove 33 at the vertical tip of the winding member 19 and 20 to prevent the formers 19 and 20 from rotating significantly.

In addition, while the movable member 36 is retreating and the engagement pin 38 is coming out of the engagement hole 22 of the lower winding form, the vertical end with the locking groove of the fixed member inserted into the end of the lower winding form 20 The portion 32 prevents large rotation of the winding forms 19 and 20, and the movable member 36
When the lower winding former 20 moves forward and the engagement pin 38 fits into the engagement hole 22, the lower winding form 20 rotates by a certain angle from the stop position where the engagement pin 38 is completely fitted into the engagement hole 22. Even if the rotation angle is within the angle allowed by the vertical base end portion 32 with a locking groove of the fixed member, the tip of the advancing engagement pin 38 is tapered and the engagement hole is closed. 22 and the winding forms 19 and 20 are rotated and returned to their stopping positions, and the engagement pin 38 is completely fitted into the engagement hole 22. In the winding machine equipped with the winding form rotation stop device of this example, the outer diameter of the rotary shaft 3 of the flyer is smaller than that of the conventional one, and the ball bearing 7 bearing the rotary shaft has a smaller diameter. Fryer 8, whose rotation speed was approximately 2.000 rF, was rotated to 6.000 rpm.
1, it can rotate at high speed, and the efficiency of winding work can be greatly improved. The winding former locking device of the present invention uses a fixed member close to the outer circumferential surface of the winding former and a movable member that locks on the tip end surface of the winding former, so it is different from the conventional locking device using a planetary gear train. There is no need to insert the support shaft of the winding form into the rotary shaft of the fryer as in the above method, and the rotary shaft of the fryer can be made small in diameter, and the bearing that supports the rotary shaft can be made small in diameter.

Therefore, the efficiency of the winding work can be improved by rotating the rotary shaft of the flyer at high speed. Furthermore, a planetary gear train with a complicated structure is not required, and the structure becomes simple.
