Since the molding means 5 configured as described above has the same structure as the clamp means 4, all the components are installed inside the housing 55, so that the configuration is simple and the exterior of the housing 55 is not complicated.

The following describes in detail the process of the present invention winding and separating the coil.

In order to wind the coil wire 3, first, each coil wire 3 wound on a bobbin (not shown) is collected as usual by the wire supply means 1 at the collecting portion, and then through the nozzle 12, the clamp means. Supply to (4). At this time, the first conveyance table 6 and the second conveyance table 7 are moved to each other in the cross direction by the control, so that the nozzle 12 is disposed at the position of the clamp 18 of the clamp means 4 so that the nozzle 12 The coil wire (3) supplied through the () is gripped by the clamp (18).

The clamp means 4 is a cylinder 23 of the shaft moving means 16 by the working fluid to move the slide member 24 in the direction of the clamp 18, the insertion pin 22 clamps the shaft 17. The variable member 20 is separated from the fixed member 19 by moving in the direction of 18. In this state, when the cylinder 23 returns to its original position, at the same time, the elastic member 25 expands to move the slide member 24, and the slide member 24 moves the shaft 17 to its end. The fixing member 19 of the clamp 18 fixed to the close contact with the variable member 20 to hold the coil wire 3 therebetween.

As described above, when the forming means 5 moves while the clamp 18 grips the coil, and the pressing member 54 is disposed to be close to one side of the winding 2, the wedge 31 is formed in the block unit ( 30 is inserted into the inclined hole 50 in the center to enlarge the outer diameter of the block unit 30, the guide pin 35 is the insertion groove of the power transmission member 68 fixed to one side of the forming means (5) 71). At this time, the blocks 29 move radially in accordance with the guide of the guide pins 35 accommodated in the guide holes 34 to expand the outer diameter of the block unit 30 while compressing the elastic member 49. . The nozzle 12 of the wire rod supply means 1 moves in the state in which the clamp 18 grips the coil so that the coil wire 3 passes through the guide groove 36 of the bracket 28. It is ready to be wound on the outer diameter.

When the motor 13 rotates continuously, the clamping means 4, the winding 2, and the forming means 5 rotate integrally, and the coil wire 3 is wound around the outer diameter of the block unit 30 to complete the winding. Done. At this time, the nozzle 12 makes it possible to uniformly stack the coil wires 3 supplied reciprocally in the width direction of the block unit 30.

Since the coils thus wound are simply wound, the wires 3 have no binding force, and thus, a process of applying power to the coils to melt the coating layers and attaching them to each other to solidify them.

The shaping means 5 is performed by the shaping means 5. As the coil coating layer is melted by the power supply and the thickness of the coil wire 3 is reduced, the thickness of the whole coil bundle wound is also reduced. In this case, the forming means 5 is formed by the pressing member 54 being wound on the coil. Press the side of the coil wires (3) to be closely molded.

Here, the forming means (5) is a cylinder 62 to move the slide member 63 in the winding (2) direction, the insertion pin 61 to move the shaft 58 in the winding (2) direction. Therefore, the pressing member 54 in contact with the coil is in close contact with the molten coil by the power supply, thereby closely attaching and solidifying the wires 3 of the coil.

When the solidification process of the coil is completed as described above, the shaft 58 of the forming means 5 is moved to its original position so that the wedge is released from the inclined hole 50 of the block unit 30. The elastic member 49 is expanded to move each block 29 in the concentric direction. Therefore, the outer diameter of the block unit 30 is reduced so that the coil wound around its outer diameter becomes loose, so that it can be easily separated.

According to the present invention constituted as described above, the clamping means and the forming means are each linearly reciprocated by the supply of a working fluid to move the shaft in one direction to open and close the clamp to hold the coil, and to reciprocally move the pressure member. The coils placed between them solidify the coils, and when the wedges are inserted into the block unit inclined holes, the respective block oils reciprocate in a radial direction to enlarge or reduce the outer diameter of the block unit so that the coil is wound. This will separate the wound coil.

Therefore, the clamp means and the molding means have all the components installed inside the housing, the exterior of the housing is clean and the configuration is compact has the advantage that can be miniaturized the winding machine.

And as described above there is also an advantage that can be easily handled when assembling the production of a compact product by mounting all the parts inside the housing.

Rotating the winding winding the coil wire has the advantage that the coil is wound on the winding without rotating the nozzle for supplying the coil wire has the advantage of winding a good quality coil.

In addition, the block unit is composed of a plurality of blocks reciprocating in the radial direction to expand the outer diameter of these blocks to winding the coil wire on the outer peripheral surface, and to reduce the outer diameter of the blocks to separate the winding coils of the winding configuration In addition to simplifying it has the advantage of reducing the number of winding coil separation maneuver.
