That is, as shown in FIGS. 4 and 5, the projecting projections 22 of the work are received in the cuts of the work receiver 93 of the pallet 90, whereby the work is correctly positioned. In particular, the work 14 can be correctly positioned not only in the height direction but also in the rotation direction.
[0031]
A pair of orthogonal robots 83 are provided to take out the work from the pallets 90 and 91 conveyed by the conveyor 89 and move the work to the winding position. Each of these robots 83 is constituted by a rodless cylinder and is for transporting a work to the pair of work receiving bases 74 and 75 shown in FIG. 1, respectively.

In FIG. 1, the illustration of the transport mechanism corresponding to the work receiving table 75 is omitted.
[0032]
Next, the bobbin 14 constituting the work on which the deflection yoke coil is wound by such a winding device will be described with reference to FIG. The bobbin 14 has a funnel-like shape in which a large opening 15 is formed in the upper part and a small opening 16 (see FIG. 9) is formed in the lower part. However, locking claws 18 are formed at the peripheral edge of the lower opening 16. A peripheral groove 19 is formed on the inner peripheral surface of the bobbin 14, and another peripheral groove 20 is formed on the base side of the lower locking claw 18. Further, a winding groove 21 is formed on the inner peripheral surface of the bobbin 14.

Further, in such a bobbin 14, a plurality of convex protrusions 22 shown in FIGS. 4 and 5 are added below the funnel flange, and the bobbin 14 is connected to the work receiving bases 74 and 75 of the wire winding portion. , And the pallets 90 and 91 can be held by the work receiving portions 85 and 86.
[0034]
Next, a control system of such a winding device will be described with reference to FIG. This control system includes a sequencer 100 and a controller 101 constituted by a numerical controller. A start / stop switch 103, an origin return switch 104, a reset switch 105, an emergency stop switch 106, and a work chuck ON / OFF switch 107 are connected to the input side of the sequencer 100, respectively.
[0035]
In contrast, the controller 101 controls the actuator 42 for moving the nozzle unit back and forth, the actuator 44 for moving the nozzle unit up and down, the motor 48 for rotating the nozzle unit, the actuator 68 for moving the guide unit back and forth, and the guide unit. And a motor 78 for rotating the bobbin. Each of these actuators 42, 44, 48, 68, 70, 78 has an encoder, and the output is fed back to the controller 101. On the other hand, the orthogonal robot 83 and the parallel chuck 84 are directly controlled by the sequencer 100 without going through the controller 101.
[0036]
In this control system, the winding operation is particularly performed by a combination of the controls of the six actuators 42, 44, 48, 68, 70, and 78 connected to the controller 101. On the other hand, the orthogonal robot 83 and the parallel chuck 84 perform operations for supplying and discharging the work.
[0037]
Next, the operation of such a winding device will be described. The wire 10 is supplied from a wire bobbin not shown. Such a wire 10 is provided with an appropriate tension by the tensioners 26 and 27, passes through the housing of the nozzle units 35 and 36, is held at the nozzle tip portion via the nozzle body, and is used for winding the wire 10. Preparation is completed.
[0038]
On the other hand, the supply of the bobbin 14 constituting the work is performed by the convex protrusion 22 of the bobbin 14 held by the concave work receivers 92 and 93 of the pallets 90 and 91 conveyed by the conveyor 89 (see FIG. 4). The concave work receivers 85 and 86 provided on the parallel chuck 84 move to clamp the bobbin 14, and furthermore, a spring 87 (see FIGS. 6 and 7) attached to the work receiver attachment portion forms a work-like flange. I try to hold the part.
[0039]
Next, the parallel chuck portion 84 moves up, and then moves horizontally toward the work receiving tables 74 and 75 by the orthogonal robot 83, and the parallel chuck 84 moves down at a predetermined position. As a result, the work 14 stands by while holding the work 14 between the transfer positions of the work receiving tables 74 and 75.
[0040]
The chucks (not shown) provided on the work receiving tables 74 and 75 are moved forward by the operation of the actuator 78 to hold the convex projections 22 of the work 14 held by the work holder 85 of the parallel chuck 84 shown in FIG. Do. At this time, the parallel chuck 84 retracts the work receivers 85 and 86, and releases the holding of the work 14. Thereafter, the parallel chuck 84 moves up and waits at that position until the winding of the wire is completed.
[0041]
Next, the nozzle units 35 and 36 hold the distal ends of the wires between the guide units 59 and 60, and move the wire 10 to the wire holding portions of the work receiving pedestals 74 and 75 by cooperative operation to hold the ends of the wires 10. Let them do it.
[0042]
The nozzle units 35 and 36 rotate their tip portions by an actuator 48 shown in FIG. 2, and cooperate with the actuator 78 and the rotation of the work receiving tables 74 and 75 performed by the operation of the rotation drive pulley 79 and the belt. The movement causes the wire 10 to be wound around the outer periphery of the funnel portion of the work 14. Thereafter, the nozzles 35 and 36 descend in the work 14, and the wire is routed to the neck of the work 14. Next, in the winding operation of the neck portion, the lower guide units 61 and 62 advance to hold the wire, and the winding of the neck portion is performed by the nozzles 35 and 36, the work receiving tables 74 and 75, and the guide units 61 and 62. And the bobbin 14 is wound around the neck portion.
[0043]
Describing in more detail, the wire 10 whose terminal is entangled with the pin is wound around the winding groove 21 of the bobbin 14 shown in FIG. Thereafter, the nozzle 35 is moved to the center of the upper opening 15 of the bobbin 14 as shown in FIG. 9, and then the nozzle 35 is moved downward as shown in FIG. The wire 10 is wound along. Then, the wire 10 that has reached the lower opening 16 is hooked on the guide chip of the lower guide unit 61, and the wire 10 is wound along the peripheral groove 20 provided outside the lower opening 16. At this time, the work receiving tables 74 and 75 rotate by an angle corresponding to the winding angle, and rotate the bobbin 14 by a predetermined angle.
[0044]
At a predetermined position in the circumferential direction, the lower guide unit 61 removes the wire 10. Then, the nozzle 35 moves upward on the contrary, and the wire 10 is hooked on the upper guide unit 59 as shown in FIG. The wire 10 is wound at a predetermined angle along the peripheral groove 20 outside the opening 15. Then, at a predetermined angular position, the guide chip of the guide unit 59 detaches the wire 10 again, and the nozzle 35 descends on the Z axis. Such an operation is conceptually shown in FIG. By repeating this operation a predetermined number of times, the wire 10 is wound along the winding groove 21 inside the bobbin 14, and a saddle coil is formed.
[0045]
When the winding of the wire 10 around the bobbin 14 is completed, the parallel chuck 84 waiting at the upper position of the winding position is lowered, and the work receivers 85 and 86 advance to clamp the work 14 and move up. One cycle of the operation is completed by transporting to the pallets 90 and 91. Since such an operation is performed for the two bobbins 14 supplied to the pair of work receiving tables 74 and 75, the two winding operations are performed in parallel.
[0046]
Next, another embodiment will be described with reference to FIGS. In this embodiment, the supply and discharge of the work 14 are performed by the slide table 111 and the mounting table 112 without using a conveyor. A pair of works 14 are placed on the slide table 111 so as to correspond to the work supports 74 and 75, and such a work 14 is supplied to the work supports 74 and 75 by the orthogonal robot 83. .
[0047]
Thereafter, the slide table 111 and the mounting table 112 are moved from the position shown in FIG. 13 to the position shown in FIG. Then, in such a state, the bobbin 115, which has been wound from the work receiving tables 74 and 75, is moved onto the slide table 111 by the orthogonal robot 83. Such a bobbin 115 is further transferred to the mounting table 112 by an operator.
[0048]
According to such a configuration, the wound bobbin 115 is moved from the slide table 111 during the winding operation on the work receiving tables 74 and 75, and the work 14 that is not wound is placed on the slide table 111. By placing the work, the work can be exchanged without any loss time, and the supply and discharge of the work can be performed without using a conveyor.
