Abstract

PURPOSE:To simultaneously achieve a winding work even when the interval of winding terminals is any by providing a mechanism having a holder arm for so holding as to slide a nozzle holder for varying the interval of two nozzles. CONSTITUTION:A winding shaft 5 driven through toothed pulleys 2, 3 and a toothed belt 4 by a motor 1 is provided, and two nozzles 8 for guiding a wire blank fed from a spool 6 are provided oppositely to the shaft 5. The nozzles 8 are secured to a nozzle holder 12 secured to a holder arm 11. The holder 12 is slidably secured by a guide plate 24 secured to the arm 11, the holder 12 is driven by a cylinder 25, and an interval of the nozzles 8 is varied by pushing and pulling the cylinder 25. Thus, the interval of the nozzles 8 is varied in coincidence with that of winding terminals 23 to simultaneously wind the two terminals 23. Therefore, the winding operation may be performed once to efficiently effect bifilar winding.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention Industrial Application Field The present invention relates to a winding device that improves the productivity of coil winding, and particularly relates to a winding device that improves the productivity of coil winding. The present invention relates to a winding device that is effective for pie filer winding.

2. Prior Art A conventional bobbin rotation type winding device was constructed as shown in Fig. 4 in plan view and Fig. 5 in side view. 3. A winding shaft 5 driven via a painter's belt 4 is installed and has two bases. Two nozzles 8 are provided opposite the winding shaft 5 to guide the wire 7 fed out from the spool 6.

9.10 is a guide roller for the wire rod 7. The nozzle 8 is fixed to a nozzle holder 12 fixed to a holder arm 11. The holder arm 11 is attached to the support frame 1 so that the nozzle 8 can be rotated vertically and horizontally.
It is supported by 3. The rotation of the holder arm 11 is performed by pushing and pulling the cylinder 14 fixed to the support frame 13 via the shaft 16, second lever 17, connecting rod 18, and third lever 19. 13 is fixed to the XYZ table 2o, and the nozzle 8 has a degree of freedom in the x, y, and z directions. , two wire rods 7 are wound around the winding terminal 23 of the bobbin 22 attached to the winding shaft 6, and the wires are wound around the bobbin 22 at the same time.

Figure 6 shows the winding operation. Here, the terminal to be wrapped is shown in black. Attempting to wind up as shown in Figure 6A 2
If the distance between the two winding terminals 23 is the same as the distance between the nozzles 8, winding can be performed at the same time, but if the distance between the nozzles 8 and the winding terminal 230 are different, the winding can be done at the same time. As shown in Figure B, the wire is first wound around one terminal, and then, as shown in Figure 6C, the bobbin 22 is rotated to bring the other terminal to a position where it can be wound, and winding is performed. In this way, each side must be wrapped twice. Moreover, by winding one end at a time, the wire 7 was repeatedly rubbed and fatigued by the 80 nozzles that were performing idle winding operations, as shown in Figure 6.

Problems to be Solved by the Invention In this conventional configuration, in the pie filer winding, unless the interval between the winding terminals 23 and the interval between the nozzles 8 are the same, even if winding is possible, it is divided into two windings. The wire rod 7 had to be wound, which took time and had a negative effect on the wire rod 7.

The present invention aims to provide a winding device that can improve the productivity of pie filer winding.

Means for Solving the Problems In order to solve the above problems, the winding device of the present invention has two nozzles each holding two nozzles for guiding the wire, facing the winding shaft for winding the wire. A holder is provided, a holder arm is provided to slidably hold the nozzle holder, and the mechanism changes the distance between the two nozzles.

Effect: With this configuration, the nozzle spacing is changed to match the spacing between the winding terminals, winding is performed simultaneously on two winding terminals, the wire is then wound on the bobbin, and the nozzle is adjusted again to match the winding terminals. This means that winding can be performed simultaneously by changing the interval.

EXAMPLE An example of the present invention will be described below with reference to the drawings.

Fig. 1 is a plan view, Fig. 2 is a side view, and Fig. 3A.

As shown in the front view and cross-sectional view of the noise holder and noise arm part in B, the motor 1 is attached to the toothed boos jl-2 and 3.
, a winding shaft 6 driven via a toothed belt 4 is provided. Two nozzles 8 are provided opposite the winding shaft 5 to guide the wire 7 fed out from the -1 to the spool 66. 9 and 10 are guide rollers for the wire rod 7. The nozzle 8 is fixed to a nozzle holder 12 fixed to a holder arm 11. The holder arm 11 is supported by a support frame 13 so that the nozzle 8 can be rotated vertically and horizontally. The rotation of the holder arm 11 is caused by the pushing and pulling movement of the cylinder 14 fixed to the support frame 13. Shaft 16, 17.2 Lever 1
7. Connecting rod 18. This is done via the third lever 19. The support frame 13 is fixed to the xYZ table 20, and the nozzle 8 has a degree of freedom in the xyz directions. 21 is nozzle 8
This is a wire chuck that holds the wire rod 7 guided by the wire rod. A bobbin/22 is attached to the winding shaft 5, and 23 is a winding terminal for the bobbin 22. Figures 3 and 3B show detailed views of the nozzle holder 12 and holder arm 11. Nozzle holder 1
2 is slidably fixed by a guide plate 24 fixed to the holder arm 11. The nozzle holder 12 is driven 6 by a cylinder 26, and the distance between the nozzles 8 is changed by pushing and pulling the cylinder 25.

As described above, according to this embodiment, the interval between the nozzles 80 is changed in accordance with the interval between the two wound terminals 23, and the two wound terminals 2
3 at the same time, only one winding operation is required, there is no adverse effect on the wire 7, and pie filer winding can be performed efficiently. Also, nozzle 8
Since the interval between the nozzles 8 can be changed both in the horizontal and vertical directions, the winding terminal 23 of the bobbin 22 can be wound in the same way whether it is a radial terminal or an axial terminal.

Effects of the Invention The present invention improves productivity by changing the spacing between two nozzles in pie filer winding, so that winding work can be done at the same time regardless of the spacing between the winding terminals. It is of excellent quality and has high industrial value.
