Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in the method of tying a wire to a terminal of a core.

When winding a wire around a core to form a winding coil, when winding the wire around a terminal that protrudes from the circumferential surface of the core, use a chuck that rotates and moves up and down the shaft on which the chuck for attaching the core protrudes. A winding machine consists of a mechanism and a flyer mechanism that rotates and reciprocates to wind the wire around the core attached to the chuck, and moves the shaft upward or downward to connect the terminal of the core to the wire guide section of the flyer. The fryer is moved to a position close to the core, and in this state, the flyer is reversed and reciprocated, and the wire is tied to the terminal of the core.

However, in the above-mentioned tying method, the shaft on which the chuck is attached is moved upward or downward in order to position the terminal of the core at a location where it can be cinched by the flyer. For this reason, it is necessary to move the shaft up and down for the flipping operation, which has the disadvantage that the drive mechanism for the shaft becomes complicated, and a drive control circuit is required, making the entire device larger.

The present invention solves the above-mentioned drawbacks and makes it possible to wrap wires around terminals that protrude in the radial direction relative to the circumferential surface of the core without vertically moving the core mounting shaft or flyer mounting mechanism. This was obtained as a result of studies aimed at providing a winding method that allows for

That is, the present invention provides a winding machine in which a chuck is horizontally protruded from a shaft rotatably installed perpendicular to the machine base, and a flyer is provided that rotates and moves horizontally in opposition to the chuck. When forming a coil using a wire machine, the terminal protruding in the radial direction relative to the circumferential surface of the core is attached to the chuck so that it is in a horizontal position, and the terminal is placed in the wire guide section of the flyer by rotating the shaft. The present invention provides a wire winding method in which the flyer is moved close to the terminal, and in this state, the fryer is moved in the chuck direction and rotated to wind the wire around the terminal.

FIG. 1 is a schematic front view of one embodiment of a winding machine that implements the winding method of the present invention, and FIG. 2 is a plan view, and the configuration thereof will be explained based on the drawings.

Reference numeral 5 denotes a drive device for rotating and reciprocating the flyer 6, and the flyer 6 is equipped with a wire winding guide.

The operation of winding the wire around the core by the winding machine having the above configuration will be explained.

First, the cores A are respectively mounted on the chucks 4 of the core mounting device 2 using a supply device (not shown). Core A
When the core A is attached to the chuck 4, the drive device 3 is activated to rotate the core attachment device 2 and move the core A to the wire winding position A. Next, the wire Y is pulled out from the supply bobbin (not shown) and passed through the guide provided in the fryer 6 via the drawer drive device 5, and the end of the wire Y is held in a predetermined position on the core A by a presser (not shown). do. In this state, a twisted wire y for twisting the wire Y to the terminal of the core A is formed using a wire twisting machine (not shown) or the like. When the twisted wire y is formed, a presser (not shown) is operated to release the holding of the wire Y, and at the same time, the drive device 5 is operated to rotate the flyer 6 and wind the wire Y around the core A. When the stranded wire is pulled out to the guide position of the fryer 6 by winding the wire Y, the drive device 3 is activated to rotate the core attachment device 2 and move the core A to the terminal binding position B.
When core A moves to terminal binding position B, drive device 5
is activated, and the fryer 6 repeats reciprocating and reversing motions to twist the twisted wire y around the terminal a. When the twisted wire y is wound around the terminal a, the drive device 3 is activated to rotate the core attachment device 2 and move the core A to the wire winding position a. When the core A moves to the wire-wrapping position A, the drive device 5 is actuated to rotate and move the flyer 6 to wind the wire Y around the core A. When a predetermined amount of the wire Y is wound around the core A, a presser (not shown) is activated to hold the wire Y at a predetermined position on the core A. Twisted wire y to be tied to another terminal a′ in this state
is formed using a wire twisting machine (not shown) or the like. When the twisted wire y is formed, a presser (not shown) is activated to release the holding of the wire Y, and at the same time, the drive device 5 is activated to rotate the fryer 6 to transfer the wire Y to the core A.
When the preset amount of winding is completed, the stranded wire y is wrapped around the guide portion of the flyer 6.
is drawn out. When the twisted wire y is pulled out to the guide portion of the flyer 6, the drive device 3 is activated to rotate the core attachment device 2 and move the core A to the terminal binding position C. When the core A moves to the terminal binding position C, the drive device 5 is actuated, and the flyer 6 repeats reciprocating and reversing movements to bind the stranded wire y to the terminal a'.
When the twisted wire y is wound around the terminal a, the drive device 3 is activated to rotate the core attachment device 2 and move the wound core A to the core removal position. During the winding operation, the core A is attached to the chuck 4' of the core attachment device 2.
Attach it. When the wire-wound core A moves to the take-out position, the core A mounted on the chuck 4' moves to the wire winding position A. When the core A moves to the wire winding position A, a presser (not shown) moves the wire Y located between the terminal a' of the core A that has been wound and the guide of the flyer 6 to the wire winding position A. It is held in a certain core A. In this state, the wire Y between the terminal a' of the core A that has been wound and the core A that is in the winding position is cut with a cutter (not shown), and the wire Y that has been wound is removed from the chuck 4. The winding operation on the extracted core A is completed by an extraction device (not shown).
