Description

[Detailed description of the invention] (Field of industrial application) This invention forms a transformer by combining a coil and an iron core consisting of two members, and a tape is wrapped around the outer periphery of the two members of the iron core combined with the coil. The present invention relates to a tape winding device that connects the tapes together.

A transformer is made up of a combination of a coil A wound with a conducting wire and an iron core B, and the iron core B is generally made up of two or more pieces, making it convenient to combine with the coil. In the example, the iron core B is an E-shaped member as shown in Fig. 6.
Showing one consisting of two members, B ₁ and I-shaped member B ₂ ,
The center part of the E-shaped member _B1 is inserted into the center hole of the coil A, and the I-shaped member _B2 is attached to the end of the inserted part to form a transformer as shown in FIG. Furthermore, iron core B
In addition to the above-mentioned E-shaped and I-shaped members, a transformer may also be formed by fitting two E-shaped members from both sides of the coil.

As mentioned above, the two members B ₁ of the coil A and the iron core B,
A tape C is wound around the outside of these two members B ₁ and B ₂ in order to assemble the two members B ₂ and join them together, and the device for winding the tape is shown in FIGS. 1 to 3.

1 is the machine casing, 2 is the rotating shaft, which is rotated at an appropriate speed by interlocking with the motor 3 installed inside the machine casing, and the above-mentioned transformer coil A is attached to the tip of the motor 3.
A holding member 4 for holding a combination of iron core B and iron core B is removably attached. The holding member 4 can be replaced at any time with a suitable one depending on the size and form of the core B, and generally the shape of the front side is the same size as the shape of the core B which is a combination of the two members. It is formed into a cylindrical shape with a space inside which can receive the protruding part of the coil A, and a mounting shaft 5 is provided at the rear, which is inserted into the rotating shaft 2 and fixed with a locking screw 6. Made exchange easier.

The holding member 4 is magnetized to attract and hold the iron core B, which is a combination of two members, by magnetic coupling.

(Function) The holding member 4 having the above structure is attached to the rotating shaft 2, and the iron core B combined with the coil A is held by suction as shown in FIG. A tape C pulled out from a freely supported reel 8 is wound around the iron core B along the upper and lower sides of a plurality of guide shafts 9, and the coil and the iron core are connected to the first
The E-shaped member B ₁ and I-shaped member B ₂ of the core B are joined together by winding tape C in multiple layers by rotating it in the direction of the arrow shown in the figure, and the tape C is cut to finish forming the transformer. , detach from the holding member 4 and take it out.

In the figure, reference numeral 10 denotes a pressing piece that prevents the coil and iron core from coming off the holding member 4 during tape winding work.It is brought into pressure contact with the coil surface by spring pressure, and when necessary, it is moved back against the spring to assemble the transformer. to detach.

In addition, as shown in the illustrated example, the iron core B is E-shaped member _B1 and I
In the case of a combination with shaped member B ₂ , as shown in FIG. 8, when winding tape C, the tension of the tape overcomes the suction force of holding member 4, and the two members B ₁ ,
B ₂ together or E-shaped member B ₁ and I-shaped member B ₂ tend to slide in the opposite direction to the rotational direction due to the reaction force when these rotate, so to prevent this sliding, it is necessary to prevent this sliding. Although the control piece 11 is provided on the holding member 4, it is not necessary to provide the control piece 11 when the iron core B is composed of two E-shaped members.

(Effects of the invention) According to the invention, the tape is wound around the combination of the coil and the iron core by mechanical operation, and the transformer is formed by joining them together, so the winding of the tape is extremely efficient. During winding, magnetic coupling is used as a means to support the coil and the core made up of multiple members on the winding rotating shaft, and a holding member made of a magnetized material is attached to the tip of the rotating shaft. Therefore, it is extremely easy to combine the coil and the iron core and hold them immovably on the rotating shaft without separating them, and it is also easy to attach and detach them.
By replacing the holding member according to the shape and size of the iron core, it can be used for many purposes, and its structure is extremely simple and has the advantage of being inexpensive.
