Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding spindle unit and a winding device for producing a coil component using a wire.

2. Description of the Related Art Conventionally, winding devices for producing coil components are roughly classified into a fryer method and a spindle rotation method, and have been manufactured as dedicated machines for each winding method.

In recent years, NC control has also been introduced in the production of coil parts, and a type has been proposed which can cope with high-mix low-volume production.

Problems to be Solved by the Invention However, in the above-described winding device, since it is dedicated for each winding method, there is a problem that high-mix low-volume production cannot be performed beyond the difference in the winding method. there were.

The present invention has been made in view of the above problems, and has as its object to provide a winding spindle unit and a winding device capable of selecting an arbitrary winding method.

Means for Solving the Problems To solve the above problems, a winding spindle unit and a winding device of the present invention include a hollow spindle shaft rotatably supported around an axis, and one end of the spindle shaft. And a mounting means for selectively removably mounting either the fryer or the work holding chuck, and a hollow shaft motor arranged on the same axis as the spindle shaft and connected to the spindle shaft. The winding wire is supplied through the hollow portion of the spindle shaft and the hollow portion of the hollow shaft motor.

According to the present invention, when winding is performed by the flyer method, the flyer is attached to one end of the spindle shaft, and the wire is supplied to the flyer through the hollow shaft motor and the hollow spindle shaft to supply the wire. In the case of the spindle rotation method, a work holding chuck is attached to one end of the spindle shaft, a work is set, and the spindle shaft is rotated to supply a wire from the outside and perform winding.

Hereinafter, a winding device according to an embodiment of the present invention,
This will be described with reference to FIGS.

In FIG. 1, reference numeral 1 denotes a winding spindle unit. A support cylinder 3 is attached to a front portion of the main body 2. Bearings 4a and 4b are fitted to the front end and the rear end of the support cylinder 3, and the front and rear of the hollow spindle shaft 5 are rotatably supported. Reference numeral 6 denotes a hollow shaft motor supported on the main body 2 so as to be coaxial with the spindle shaft 5.
At the rear end of the spindle shaft 5. A mounting portion 11a of a fryer 11 is fitted to a fitting shaft portion 5a at the front end of the spindle shaft 5 protruding forward from the support cylinder 3, and is fixed by a nut 8. The flyer 11 has a mounting portion 11a
Has arms 12a, 12b extending in a U-shape on both sides from one arm
A delivery nozzle 13 is provided at the free end of 12a, and wire guides 14a and 14b for guiding the wire 10 supplied through the hollow portions of the hollow shaft motor 6 and the spindle shaft 5 to the delivery nozzle are provided.

As shown in FIG. 2, a work holding chuck 15 can be attached to the fitting shaft portion 5a of the spindle shaft 5, instead of the fryer 11. That is, in FIG. 2, the mounting portion 15 of the work holding chuck 15 is attached to the fitting shaft portion 5a of the spindle shaft 5.
a is fitted and fixed with a nut 8. 16 is a chucking part of a lining type of the work holding chuck 15, 17 is an opening / closing piston having a tapered part 17a at the tip end for opening and closing the chucking part 16, 18 is a spring for urging the opening / closing piston 17 to project, 19 is a spring 18 This is an air supply port for retracting the opening / closing piston 17 against the urging force of the opening / closing piston 17.

FIG. 3 shows the overall configuration of the winding device 20, showing a state in which winding is performed by a spindle rotation method. Reference numeral 21 denotes a gantry, and robots 22a and 22b are provided at diagonal positions on the upper surface, respectively.
The spindle unit 1 is mounted on one of the robots 22a, and the work holding chuck 15 is mounted on the spindle shaft 5. At the center of the gantry 21, a work storage tray 23, which stores a plurality of works in alignment, is positioned and mounted. Also, this work storage tray 23
And a wire feeder 24 at a position adjacent to the other robot 22b.
The robot 22b is provided with a wire guide 25 for guiding the wire 10 supplied from the wire feeder 24 so as to be wound around the work held by the work holding chuck 15.

Next, the winding operation by the flyer method will be described. In this case, although not shown, the flyer 11 is attached to the winding spindle unit 1 mounted on one of the robots 22a in FIG. 3 as shown in FIG. Then, the wire rod 10 is supplied from the wire rod supply device 24 toward the rear end, and a work holding chuck is appropriately attached to the other robot 22b. And
The other robot 22b sequentially takes out the work from the work accommodating tray 23, positions it at the center of the fryer 11, holds the wire 10 at the terminal of this work, and drives the spindle shaft 5 to rotate by the hollow shaft motor 6. Thereby, the work can be wound. The wire 10 is supplied to the fryer 11 through the hollow shaft motor 6 and the shaft hole of the spindle shaft 5.

Next, the winding operation by the spindle rotation method will be described. In this case, as shown in FIG.
The work holding chuck 15 is mounted on the winding spindle unit 1 mounted on the winding robot 22a, and the other robot 22
Attach wire guide 25 to b. And one robot 2
2a is operated, the work is taken out from the work storage tray 23 by the work holding chuck 15 at the tip of the spindle unit 1, is positioned in a horizontal position under the wire guide 25, and the wire 10 is held at the work terminal to hold the work. Chuck 15
Is rotated by a hollow motor 6 via a spindle shaft 5 so that the workpiece can be wound.

Although the hollow shaft motor 6 is connected to the rear end of the spindle shaft 5 in the above embodiment, the hollow shaft motor may be built in the hollow spindle shaft.

Effect of the Invention As described above, according to the present invention, a hollow spindle shaft and a hollow shaft motor are connected to each other, and a flyer or a work holding chuck can be selectively attached to a distal end portion of the spindle shaft. This makes it possible to use both the winding method of the spindle rotation method and that of the spindle rotation method.

In addition, since the spindle shaft and the hollow shaft motor are standardized as the winding spindle unit, a compact and lightweight structure can be achieved, and the lead time of the winding device equipped with the winding spindle can be shortened.
