Even if the auxiliary holding part is not provided, it can sufficiently fulfill its role.

The holding part of the Γ wire may be configured to be held by a hollow shaft and a shaft having a flange as in the embodiment,
It may also be configured to be held between two movable claws.

The Γ cutting device is moved from a standby position to an operating position by a powder cylinder as in the embodiment, and
It may be a scissor-shaped cutter that cuts the wire at the operating position, or it may be configured such that a single movable cutter moves from the standby position to the operating position and presses it.

Further, the installation position may be above the spindle, but it may also be installed below the spindle and parallel to the presser.

ΓConfirming each operation and detecting the amount of movement may be performed using a contact type sensor or a non-contact type sensor.

The drive device such as the Γ pulse motor is operated by a numerical control device, the sensor, etc.

When two or more types of wire rods are wound around one bobbin Γ, this can be easily handled by arranging a wire supply section, a clamping section, and a winding nozzle corresponding to the types of wire rods.

Claims (1)

[Claims] 1 a spindle rotatably mounted on a fixed frame and to which one bobbin is mounted; a movable frame mounted on the fixed frame so as to move at least in the vertical and horizontal directions perpendicular to the axis of the spindle; A wire winding nozzle is mounted on the movable frame to face the bobbin mounting portion of the spindle, and a wire clamping member is movably installed in a position close to the bobbin mounting portion of the spindle and within a movement trajectory of the winding nozzle. 1. A winding machine characterized in that a plurality of pairs of winding nozzles and wire clamping tools are installed on one spindle to which the one bobbin is mounted.
