Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for winding a wire around a coil bobbin to produce a coil, and more particularly to a mechanism for tying an end of the wire around a terminal provided on the bobbin after winding. .

[0002]

2. Description of the Related Art In the work of winding a bobbin required for manufacturing a coil, it is necessary to entangle a wire with a terminal provided on a flange at one end of the bobbin before and after starting the winding.

In an automatic winding machine for automatically winding a bobbin, this entanglement work is performed, for example, by a nozzle for feeding a wire material for winding orbiting around the terminal several times. There is.

When the wire is made thick by twisting a thin wire such as a thick wire or a litz wire, the wire is wound in layers from the base end to the tip of the terminal as the nozzle goes around the terminal. In the entanglement work before winding, the wire rod wound around the terminal is wound on the bobbin as it is, so the starting end of the wire rod is sandwiched between the wire rod that is guided from the terminal to the bobbin body and the flange at the base end of the terminal and can be unwound There is no such thing.

On the other hand, in the entwining work after winding, the wire is guided from the bobbin body to the terminal and wound from the base end of the terminal toward the tip, so that the end of the wire after winding is placed between the wires. It becomes impossible to pinch.

For this reason, it is necessary that the end of winding should come to the base end side of the terminal. However, when the wire is entangled with the terminal only by moving the nozzle, the wire from the bobbin body to the terminal and the terminal Such a entwining operation is impossible because the wire rod from the nozzle to the nozzle interferes with each other.

Therefore, for example, in Japanese Utility Model Laid-Open No. 55555/1993, the wire after winding is not immediately entwined with the terminal, but is entwined with a temporary entanglement pin provided separately, and then the entanglement pin is inverted. A mechanism has been proposed in which the tip of the terminal is coaxially contacted and the entangled portion is transferred from the temporary entanglement pin to the terminal.

In the state of being transferred to the terminal, since the end of the wire that has been entangled is sandwiched between the wire and the flange extending from the bobbin body to the terminal, the end of the wire is locked to the terminal, The entangled part becomes unsolvable.

[0009]

In this entanglement mechanism, the entanglement portion is moved from the temporary entanglement pin to the terminal by moving the nozzle. In other words, the nozzle moves laterally in parallel with the axis of the temporary binding pin and the terminal at the coaxial position, so that the binding portion to the temporary binding pin is pulled and transferred to the terminal. Therefore, the temporary binding pin has a larger diameter than the terminal.

However, this transfer operation performed only by pulling one end of the wire is not reliable, and the entangled portion may not move smoothly from the temporary entanglement pin to the terminal.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a terminal binding mechanism capable of reliably transferring a wire binding portion from a temporary binding pin to a terminal. .
