Regarding machines. [Summary of the Invention] For example, in a winding machine that forms a coil by inserting a wire with a hook-like hook into the insertion portion consisting of a small hole in the head core of a video head, the wire is inserted into the insertion portion of the head core. In addition to the hook for inserting the wire, a dedicated hook for routing the wire through the opening or bow groove for routing the end of the wire from the bottom side to the top side of the head base is provided. The winding machine operates quickly to shorten takt time and improve reliability. K. Prior Art l As disclosed in Patent Application Publication No. 1988-500819, a hook-type winding machine has been proposed for winding a wire around the insertion portion of a helad core of a magnetic head. . Furthermore, the applicant of the present application has proposed a hook type winding machine in Japanese Patent Application No. 63-203020, which is capable of reducing damage to the wire and increasing the winding speed of the wire. The hook type winding machine proposed in Japanese Patent Application No. 63-203020 winds wire as shown in FIGS. 11 to 14. Taking a single head used in a home VTR as an example, a hook 4 is used in a winding machine that winds a wire while inserting a wire 3 into an insertion hole 2 of a head core 1. The hook 4 moves in the Y-axis direction as shown in FIG.
A wire rod 3 is inserted through the insertion hole 2 of the wire rod 3. Thereafter, the wire rod 3 is wound around the head core 1 by rotating the routing clamper 5 in the θ direction. That is, the movements of the hook 4 and the clamper 5 are linked to each other, the wire 3 is hooked to the hook 4, the wire is passed through the insertion hole 2 of the head 1 by the hook 4, and the clamper 5 is then moved relative to the head core 1. The wire rod 3 is wound around the wire rod 3 as shown in FIG. The hook 4 is bent into a hook shape on the YZ plane. In addition to the hooks 4 shown in FIGS. 11 and 12, hooks 4 are also provided on the opposite side of the head core 1 symmetrically with respect to the X-2 plane, so that a total of two hooks 4 are used to wind the wire. I have to. This is to provide flexibility in the winding direction. Then, if the winding is done as shown in Figure 13, the wire 3
terminal must be connected to the terminal board on the head base. Therefore, the wire rod 3 is routed to the front side. Therefore, in the past, the end of the wire 3 was routed to the front side of the head base in the following manner. That is, as shown in FIG.
Another hook 7 located symmetrically to the hook 4 shown in the figure
The wire rod 3 is hooked thereon and passed through the routing opening 8 of the head base. This is because hook 7 is
This is because it is bent in the Y-Z plane. As shown in FIG. 14, the hook 7 or the herad core 1 is moved in the Z-axis direction by the offset amount shown in FIG. . [Problems to be solved by the K invention] According to such a conventional wiring structure of the wire rod 3, Y-
Because the hook 4.7 is bent on the Z plane,
The wire must be hooked onto the routing bin 6, which has the drawback of increasing takt time and reducing winding productivity. In addition, the length of the hook 7 must not only correspond to the insertion hole 2 of the herad core 1, but must also correspond to the routing opening 8 of the head base, which poses problems in the reliability and lifespan of the hook 7. In addition, the insertion hole 2 of the herad core 1
Although the routing opening 8 is larger in area than the above, since it is used for multiple purposes, the hook 7 cannot be increased in size, making it difficult to improve reliability. The present invention has been made in view of these problems, and it is an object of the present invention to provide a hook-type winding machine that has improved reliability and shortened takt time. Means for Solving Problem K] The present invention provides a method for winding the wire by inserting the wire through the insertion portion of the workpiece using a hook, and rotating a clamper that grips the wire relative to the workpiece. and further, in a winding machine, the end of the wire rod is routed from one side of the base holding the workpiece to the other side through a routing opening or a routing groove, and connected and fixed at a predetermined position. A hook separate from the hook for inserting the wire through the insertion portion of the workpiece is provided, and the end of the wire is passed through the routing opening or the routing groove using the separate hook. Effect 1 Therefore, there is no need for intermediate processing between the winding position of the insertion part of the workpiece and the movement of the wire to the terminal opening or routing groove, and the wire can be directly passed through the routing opening or routing groove. This makes it possible to improve reliability and shorten takt time. In addition, since it is possible to provide a dedicated hook for passing through the routing opening or routing groove, the degree of freedom in the shape of the hook is increased, and each hook can be dedicated, improving reliability. It will be planned. Embodiment K] FIG. 1 shows the state of winding by a hook-type winding machine according to an embodiment of the present invention.
Winding is performed on the helad core 12 of the magnetic head. A head core 12 made of ferrite is attached to the tip of the head base 11. This head core 12 has an insertion hole 13 that communicates with the gap.

By inserting the wire rod 16 through the insertion portion 13 and winding it by the clamper 17 for routing, the wire rod 16 is wound around the head core 12 to form a magnetic head. A pair of hooks 14 for inserting the wire rod 16 into the insertion portion 13.
In addition to 15, the winding machine is equipped with another hook 18. The hook 18 is for routing the end of the wire 16 that has finished winding through the routing opening 19. As shown in FIG. 4, it is connected by soldering to a connection pattern 22 of a terminal board 21 mounted on a head base 11, thereby allowing the magnetic head to be assembled. FIG. 2 shows an example of a double head, in which a pair of helad cores 12 are attached to the tip of a single helad base 11, and wire rods 16 are inserted into the insertion holes 13 of these helad cores 12. It is designed to be wound. Then, the wire rod 16 is inserted through the insertion hole 13 and wound.
Once the coil is formed, its terminal is routed to the front side of the head base 11 through the routing groove 20, and then, as in FIG. I am trying to connect 16 terminals. 5 and 6 show the specific structure of the main parts of such a hook type winding machine, and this winding machine is equipped with a rail 24 extending in the horizontal direction, 2
A pair of movable plates 25 and 26 are supported on the rail 24 so as to be movable in the longitudinal direction of the rail 24. And movable plate 25.26
