The guide roller 2 is also fixed to the X-axis unit 8 by a bracket 15.

Next, the main shaft section, as shown in FIGS. 5 and 6, is composed of a part that chucks and clamps the workpiece, and a main shaft part that coaxially holds the workpiece and clamps the lead wire. 151'i Crank lever and roller 16 at the tip
By pressing , it is possible to attach and detach the workpiece. 17 is a workpiece receiving block, and a workpiece position regulating pin 18
9, this workpiece chuck part is attached to the tip of the main shaft 19 (5-2). A timing pulley 20 for transmitting rotational drive is attached to the main shaft 19, and is held within a main body block 22 by a bearing 21.

One of the main shafts 19 has a mechanism for clamping the tap lead wire, and by opening and closing the lever 23, the lead wire held at a distance from the guide plate is released.

25 causes the lever 26 to swing,
A roller 27 is connected to the tip of the lever 26, and when a roller guide 28 that guides the roller 27 moves back and forth, the lever 23 swings around a fulcrum pin 29 by a spring 30.

This creates a gap between the guide 24 and the lever 23, allowing the tap lead wire to be attached and detached.

Next, the line cut clamp part is shown in Figures 9 and 10.

As shown in FIG. 11, it consists of a cutting section, a clamping section, and an actuator section that raises and lowers both heads.

First, regarding the cutting part, the cutters 31 and 32 are attached to the left and right levers 33 and 34, respectively.
3.34 is attached to block 36 by abutment pin 366. Also lever 33.
Rollers 37 and 38 are attached to one side of 34 by support pins 39. The rollers 37 and 38 are oscillated by the vertical movement of the piston pin 4o, and the opening and closing operations of the cutters 31 and 32 are obtained. By a similar mechanism, the wire clamp claw 41
．． 42 is opened and closed by the vertical movement of the piston pin 43 via rollers 44 and 45, and 46 is the piston pin 40.
It is a return spring, and 47 is a spring for wire clamping via the piston pin 43.

The entire block 36 is fixed to a slide shaft 48,
The entire device moves up and down as the slide shaft 48 moves up and down. 49
is a vertical actuator, 5o is a block that connects the block 36 and the actuator 49, and 51 is a fastening nut. Reference numeral 52 denotes a guide bearing for the slide shaft 48, which is fixedly supported within the block 53. 54
．． 55 is a bracket for connection to the main body.

Furthermore, a wire supply section is one in which a wire rod 57 is placed on a placing base 56, and the wire is supplied to a tension device 59 through a guide ring 58 (7, -8).

60 is a stand that supports the guide ring 58 and the tension device 59. Furthermore, the conveyance main body includes a jig 61 for regulating the conveyance of the workpiece, and a motor 6 for driving the jig 61 for conveyance.
2. Bracket 6 that supports the line cut crank part and main shaft part
3, an upper plate 64 that fixes each part, and a main body frame 65 that supports the whole.

Next, the operation of the embodiment will be described. The bobbins to be wound without a groove pass through the parts feeder 1 and the linear feeder 2, are aligned, and are set on the transport jig 61 by the pick-and-place unit 3. The successively fed works are extracted from the jig by the insertion chuck 4 and lifted up, turned horizontally by the turning cylinder 6, and placed on the receiving block 17 of the winding head. After receiving the attachment confirmation signal, the x, y, z three-axis orthogonal robot starts moving from the origin and winds the wire supplied through the nozzle 11 attached to the tip of the Z-axis unit 10 around the tap of the bobbin. 〇After completing one turn of constant constant rotation, next, move the main shaft 19 to the timing pulley 20.
The wires supplied from the nozzle 11 are wound on the bobbin in an aligned manner by rotating the bobbin via the drive motor and simultaneously operating the Y-axis unit "9."

After completing a predetermined number of turns, the Z-axis unit 1o is operated to slightly raise the nozzle 11, and the main shaft 19 and the X-axis unit 9 are horizontally moved in the opposite direction to the first layer, thereby completing the second layer of aligned winding. After completing the predetermined number of windings, the wire is wound around the next tap in an arc motion using the three axes of X, Y, and Z. After the predetermined number of wires have been wound, the tap is again driven using the three axes of x, y, and z. Pull out the wire and hook the wire to the lever 23 attached to the main shaft 19. Thereafter, the nozzle 11 is returned to the workpiece side again, and a predetermined number of taps are wound around the taps of the workpiece. Then, by interlocking the main shaft 19 with the three axes of x, y, and z, the above-mentioned aligned winding becomes possible.

After completing the predetermined alignment winding, perform the necessary tap winding at the highest position, position the nozzle 11 again on the main body block 229-3-ge side, raise the tuya cutters 31 and 32 by the actuator 53, and first, Line clamp claw 41
．． 42 to hold the wire, then cutter 31.32
Cut by.

Then, by operating the cylinder 25 and releasing the lever 23, the tap lead-out line can also be freely removed from the main shaft 19. Thereafter, the chuck 4 of the insertion head advances again to grab the workpiece after winding, and the rotation cylinder 6 changes the posture of the workpiece in the vertical direction and returns it to the transport jig 61. Through this series of operations, automatically aligned windings can be continuously performed.

Effects of the Invention As is clear from the above explanation, according to the winding device of the present invention, tapping of bobbins, etc., and alignment winding are possible with simple and small equipment, and by using a three-axis orthogonal robot, Changes in winding specifications can be easily accommodated.
