Incidentally, in FIGS. 1 to 5, the illustration of the coil bobbin is omitted because it would be complicated.

First, the basic arrangement will be explained.

As shown in FIG. 1, in this embodiment, a parts feeder 1 faces a shuttle 10 that horizontally moves a finger unit 11 holding a coil bobbin 2, and supplies a coil bobbin 2 to the finger unit 11, and receives a coil bobbin from the finger unit 11. A main body of a winding machine 4 for winding the wire is arranged.

In addition, 3 is a spindle for rotating the coil bobbin 2 attached to the main body of the winding machine 4 to perform winding, and 5 is a spindle for winding the coil bobbin 2 attached to the spindle 3, or after winding is completed. This mechanism moves the nozzles that guide the winding all at once when the terminal is connected to the terminal.

In addition, the coil bobbins 2 and 2 of the parts feeder 1
The outlet for discharging and supplying the coil bobbin 2 is arranged at a position facing the pin into which the coil bobbin 2 is to be inserted, with the finger unit 11 facing downward. Further, the spindles 3, 3...3 are positioned so that the coil bobbins 2, 2...2 can be delivered to the winding machine 4 when the finger unit 11 is in a horizontal position (indicated by the two-dot chain line in FIG. 1). It is located in

On the other hand, facing the shuttle 20 that horizontally moves the finger unit 21 holding the coil bobbin, there is a soldering process apparatus 70 having a solder bath 71 for soldering the terminals of the coil bobbin 2 that has already been wound, and , a cleaning machine 72 having a cleaning tank 73 containing a cleaning liquid to remove impurities attached during soldering, a hot air blower 74 having a hot air outlet 75 that blows out hot air for drying after cleaning, and a hot air blower 74 for cleaning windings. A defective product sorter 76 having a sensor section 77 for conducting a continuity test, etc., and a defective product discharging mechanism 78 for discharging the defective products into a case 79 for storing the defective products are arranged in a line. Note 8
0 is a conveying device that conveys a pallet 81 that receives complete products in line.

Further, the solder tank 71, the cleaning tank 73, the hot air outlet 75, and the defective product discharge mechanism 78 are arranged in a straight line facing the coil bobbins 2, 2...2 when the finger unit 21 moves downward. .

Next, the drive mechanism for the finger units 11 and 21 will be explained. As shown in Figure 1, the first
A moving plate 12 having an internal thread is fixed to a finger unit 11 of a shuttle 10 and is fitted into a ball screw 13. When the ball screw 13 is rotated by the motor 14 via the shaft coupling 15, the movable plate 12 moves horizontally as shown by the arrow in the figure, and the finger unit 11 also moves above the linear guide rail 16. can be moved horizontally.

Similarly, a moving plate 22 with an internal thread is fixed to the finger unit 21 of the second shuttle 20.
is fitted into the ball screw 23. Therefore, when the ball screw 23 is rotated by the motor 24 via the shaft coupling 25, the moving plate 2
Since the finger unit 2 moves horizontally as shown by the arrow in the figure, the finger unit 21 can also be moved horizontally along the linear guide rail 26.

Finger unit 11 of first shuttle 10
is fixed to the rotating shaft 32 by shaft mounting blocks 33, 33, as shown in FIGS. 2 and 3.

The rotating shaft 32 is rotatably supported by ball bearings 35, 35 on a movable table 47 that can move horizontally on the linear guide rail 16. Note that the moving table 47 is movably supported on the linear guide rail 16 by a linear guide 48.

On the other hand, the rotating shaft 32 is coupled to the rotary actuator 30 via a shaft coupling 31. Therefore, by driving the rotary actuator 30, the bobbin insertion pin 4 that holds the coil bobbin is inserted.
The orientation of the bobbin 1 can be changed from sideways (the central axis of the bobbin to be held is horizontal) to downward (the central axis of the bobbin to be held is vertical) by rotating 90 degrees, and the orientation of the bobbin insertion pin 41 can be changed from downward to downward. You can also turn it horizontally.

Similarly, the finger unit 21 of the second shuttle 20 is secured to the rotating shaft 52 by shaft mounting blocks 53, 53, as shown in FIGS. 4 and 5. The rotating shaft 52 is rotatably supported by ball bearings 55, 55 on a moving table (not shown) that can move horizontally on the linear guide rail 26.

On the other hand, the rotating shaft 52 is coupled to the rotary actuator 50 via a shaft coupling 51.

Therefore, by driving the rotary actuator 50, the direction of the bobbin insertion pin 61 that holds the coil bobbin is changed from sideways (the center axis of the bobbin being held is horizontal) to downward (the center axis of the bobbin being held is vertical). It is also possible to change the direction of the bobbin insertion pin 61 from downward to sideways.

Next, the structure and operation for advancing and retracting the bobbin insertion pins 41, 61 and bobbin removal plates 42, 62 attached to the finger unit 11 or 21 will be explained.

As shown in FIGS. 2 and 3, the bobbin insertion pin 41 is attached to a pin mount 38 that moves together with a linear guide 36 that freely moves along a linear guide rail 37 attached to the finger unit board 34. It can be replaced depending on the size and shape of the coil bobbin being handled. The pin mount 38 is coupled to the movable part of the air cylinder 40 via a pin mount drive plate 39.
The air cylinder 40 is attached to the finger unit board 34.
Therefore, by operating the air cylinder 40, the pin mount 38, and thus the bobbin insertion pin 41, can be moved forward or backward in the direction of the central axis of the coil bobbin held by the pin.

Further, as shown in FIGS. 2 and 3, the bobbin removal plate 42 is connected to the pin mounting base 38 via a linear guide 44 and a linear guide rail 43 so as to be freely movable along the linear guide rail 43. . On the other hand, the bobbin removal plate 42 is connected to a movable block of a thin air cylinder 46 via a bobbin removal plate drive plate 45. Air cylinder 4
6 is fixed to the pin mount 38, so
By operating the air cylinder 46, the bobbin removal plate 42 can be moved forward or backward relative to the bobbin insertion pin 41.

Similarly, as shown in FIGS. 4 and 5, the bobbin insertion pin 61 is driven by a pin mounting plate that moves in unison with a linear guide 56 that freely moves along a linear guide rail 57 attached to the finger unit board 54. It is attached to a pin attachment plate 58 fixed to a stand 59, and can be replaced depending on the size, shape, etc. of the coil bobbin to be handled.

The pin mounting plate 58 is connected to the pin mounting plate drive base 59
It is coupled to the movable part of the air cylinder 60 via. Since the air cylinder 60 is fixed to the finger unit board 54, the air cylinder 60
By this operation, the bobbin insertion pin 61 can be moved forward or backward in the direction of the central axis of the coil bobbin held by the pin.

Further, the bobbin exclusion plate 62 is shown in FIGS. 4 and 5.
As shown in the figure, it is connected to the pin mounting plate 58 via a linear guide 64 and a linear guide rail 63 so as to be freely movable along the linear guide rail 63. Further, a thin air cylinder 66 is fixed on the bobbin removal plate driving plate 65, and its movable part is the rising part 6 of the pin mounting plate driving plate 59.
Fixed to 7.

Therefore, by operating the air cylinder 66, the bobbin removal plate 62 can be moved forward or backward relative to the bobbin insertion pin 61.

Next, a method of transferring the coil bobbin 2 will be explained.

Fig. 6 is a perspective external view of the coil bobbin 2 shown in Figs. is applicable.

FIG. 7 is an explanatory cross-sectional view showing a situation in which the coil bobbin 2 is transferred from the finger unit 11 of the first shuttle 10 to the finger unit 21 of the second shuttle 20.

FIG. 8 is an explanatory cross-sectional view showing a situation in which the coil bobbin 2 is supplied and held from the parts feeder 1 to the finger unit 11 of the first shuttle 10.

FIG. 9 is an explanatory cross-sectional view showing a situation in which coil bobbins 2 held in the finger unit 21 of the second shuttle 20 that are determined to be defective as a result of a winding check are excluded.

FIG. 10 is an explanatory diagram showing, in cross section, the situation when the coil bobbin 2, which is a finished product after all processes have been completed, is removed from the finger unit 21 of the second shuttle 20 and is discharged to be transferred to a conveying pallet. First, when inserting the coil bobbin 2 as shown in FIG. 6 into the bobbin insertion pin 41 of the finger unit 11 of the first shuttle 10, as shown in FIG. The bobbin insertion pin 41 is moved downward with the tip thereof facing downward. Next, the first coil bobbin 2 aligned by the bobbin discharge port alignment bar 1a at the outlet of the parts feeder 1 is held by a fork-shaped bobbin holder (not shown), and the coil bobbin 2 is moved to the position 2a in the figure. Once it is at position 2b in the figure, push it upward and insert it into the bobbin insertion pin 41 at position 2c in the figure. Since the bobbin insertion pin 41 is provided with a long crack along the axial direction, the coil bobbin is held without falling due to the repulsive force due to its elasticity.

When transferring the coil bobbin 2 from the finger unit 11 of the first shuttle 10 to the spindle 3 of the winding machine 4, and when transferring the coil bobbin 2 from the finger unit 11 of the first shuttle 10 to the finger unit 21 of the second shuttle 20, , is carried out by the method shown in FIG. FIG. 7 shows a case where the receiving side is the finger unit 21 of the second shuttle 20.

FIG. 7a shows that the finger unit 11 holding the coil bobbin 2 horizontally after winding has moved in front of the finger unit 21, and the center line of the bobbin insertion pin 41 is aligned with the bobbin insertion pin that should receive the coil bobbin 2. 61 is shown stopped at a position that coincides with the center line. From this state, the bobbin insertion pin 41 and the bobbin removal plate 42 are moved forward together, and the front ends of the bobbin insertion pin 41 and the bobbin insertion pin 61 are brought very close to each other, as shown in FIG.

Next, as shown in Figure c, by moving only the bobbin removal plate 42 forward, the bobbin insertion pin
The coil bobbin 2 held at 1 is transferred to and held at the bobbin insertion pin 61. After that, the bobbin removal plate 42 and the bobbin insertion pin 41 retreat,
Return to initial state.

Next, finishing steps are performed on the wound coil held in the finger unit 21 of the second shuttle 20 with the bobbin insertion pin 61 facing downward.

Coil bobbin 2 determined to be a defective product by the sensor unit 77 of the defective product sorter 76 during the winding finishing process
When the product arrives in front of the defective product discharge mechanism 78 under the control of a control device (not shown), as shown in FIG.
Ejection bar 7 provided in defective product ejection mechanism 78
8a is the bobbin removal plate 6 of the finger unit 21.
After inserting the bobbin insertion pin 61 between the tip of the coil bobbin 2 and the brim of the coil bobbin 2 determined to be defective,
By retreating the bobbin removal plate 62 upward, the holding of the coil bobbin 2 is released and the coil bobbin 2 is allowed to fall.

Finally, when all processes are completed and the coil bobbin is to be discharged from the device, use the second shuttle 2.
0, the pallet conveying device 8 for unloading the bobbin
When the coil bobbin 2 held at a predetermined position above the pallet 81 is moved and only the bobbin removal plate 62 is moved downward as shown in FIG. A pallet 81 (not shown) falls out from the
are placed at predetermined positions divided into squares.

In this way, the coil bobbin 2 can be transferred between each device without relying on conventional robots.
All of this can be achieved through the cooperation of the first and second shuttles and each device.

In addition, the winding device including the supply and guide of the winding wire, and each device for the winding process including processes such as soldering, cleaning, drying, defective product selection, and defective product discharge, use known techniques or a combination thereof. The explanation is omitted because it is configured as follows.

However, the operations of each of these devices and the operations of the first and second shuttles, including each part of the finger unit, are all controlled by an electronic control device (not shown) containing a built-in computer.

(Effects of the Invention) As described above in detail, the present invention has two shuttles as a first bobbin transport device and a second bobbin transport device that move the coil bobbin in the horizontal direction, and the coil bobbin is moved from the parts feeder to the first bobbin transport device. from the first shuttle to the winding machine, receive the wound coil bobbin from the winding machine to the first shaft, pass it from the first shuttle to the second shuttle, and from the first shuttle to the second shuttle. By performing the winding finishing process while the coil bobbin is held, there is no need for a robot to transfer the coil bobbin, so continuous automatic control can be performed smoothly in a simple procedure throughout the winding process and winding finishing process. It has the effect of being able to be carried out.

Additionally, because no extra space is required for the installation of the robot, and because each winding device can be placed in a straight line along the second shuttle at the shortest possible distance, the winding device and winding device can be installed in an extremely narrow space. This has the effect that the line finishing devices can be arranged together.
