Description

Description: TECHNICAL FIELD The present invention relates to a wire rod winding device that winds a wire rod such as an electric wire around a bobbin.

[Conventional technology]

As a conventional wire winding device of this type, for example, Japanese Patent Publication No.
No. 50637 is known.

This conventional structure has a first holder attached to the end of the winding shaft, and a rotatable second holder which is arranged so as to face the first holder and is driven in the axial direction of the winding shaft. A bobbin is held between the first and second holding tools, and the winding shaft and a traverse mechanism that guides the wire rod in the axial direction of the bobbin cooperate with each other to hold the bobbin on the bobbin. It is configured to be wound up.

A wire that has a hole through which the first holder is passed and is held so as to be displaceable in the axial direction of the winding shaft, and is normally urged by a spring in the direction toward the second holder. A holding body and a grip arranged near a gap formed between the brim of the bobbin and the wire holding body to hold and release the wire rod before the bobbin is held by each holder. A mechanism, a rotation mechanism that rotates the grip mechanism between a first position near the traverse mechanism and a second position where the gripped wire is stretched through the gap, and the grip mechanism is the first mechanism. A cutting mechanism that cooperates with the grip mechanism when the bobbin is held in the first and second holding tools when the bobbin is held in the first position. The wire rod gripped by the grip mechanism It is held between the collar of the bobbin and the wire restraining body and the grip of the wire rod by the grip mechanism is released, and when the bobbin is fully wound, the grip mechanism is in the first position and grips the wire rod. At the same time, the cutting mechanism cuts the wire between the grip mechanism and the full bobbin.

[Problems to be Solved by the Invention]

However, in the case of the above-described conventional structure, when the bobbin is replaced, the grip mechanism holds the wire rod located between the traverse mechanism and the bobbin at the first position, and the cutting mechanism holds the wire rod located between the grip mechanism and the bobbin. The grip mechanism is rotated in the same direction as the bobbin rotates, and the wire rod held by the grip mechanism at the second position is held between one side surface of the bobbin collar and the wire restrainer and the wire rod is held. Is released, the grip mechanism is rotated in the direction opposite to the direction in which the bobbin rotates, and is made to stand by at the second position, that is, holding and release of the grip mechanism,
The bobbin is exchanged by the actions of the reciprocating rotation of the grip mechanism and the cutting of the cutting mechanism, which has a disadvantage that the work efficiency of the bobbin exchange is lowered.

[Means for Solving the Problems] The gist of the present invention will be described with reference to the accompanying drawings.

A holding mechanism 4 for holding the bobbin 3 on the winding shaft 2 and a traverse mechanism 5 for guiding the wire W back and forth in the axial direction of the bobbin 3.
And a line restraining body 30 which can be brought into contact with the base side surfaces of the bobbin 3 on the winding shaft 2, and a rotary plate 35 attached to the line restraining body 30 is provided on the winding shaft. It is provided rotatably on the second cylinder 34,
A grip mechanism 33 for gripping the wire W between the traverse mechanism 5 and the bobbin 3 so as to be retained and released is provided on the rotating plate 35 in parallel with the winding shaft 2, and the wire W of the grip mechanism 33 is gripped. The bobbin 3 is located at the base side-to-side surface and the line restraining body.
A rotating mechanism 45 is provided so as to be located outside the gap S formed between the rotating plate 35 and the rotating plate 35 and rotates the rotating plate 35 in a direction opposite to the rotating direction of the bobbin 3 and stops at a predetermined position. The grip mechanism 33 is engaged with the wire rod W between the traverse mechanism 5 and the bobbin 3 with the rotation of the rotating plate 35 to release the grip of the grip mechanism 33 to a position where the wire rod W is indexed. A wire rod holding cam mechanism 42 for introducing and holding W is provided on the rotary plate 35 and the shaft cylinder 34, and when the grip mechanism 33 cuts the wire rod W by the pivotal advance of the rotary plate 35, the rotary plate 35 stops. In the meantime, the fully wound bobbin can be removed, and the rotating plate 35 is further rotated and moved forward so that the wire W between the traverse mechanism 5 and the bobbin 3 is pressed against the base side surface of the bobbin 3. When the body 30 moves to a position where it can be held, the rotary plate 35 is stopped and a new bobbin 3 Insert the holding mechanism 4
The wire rod W is again held by the base side faces of the new bobbin 3 and the wire restraining body 30 when held by the gripping mechanism 33. The wire rod release mechanism 44 for releasing the wire rod W held at the position opposite to the bobbin 3 is provided with the rotating plate 35 and the shaft tube 34.
The wire winding device is characterized in that the grip mechanism 33 is returned to the starting position, the exchange bobbin 3 is rotated in the opposite direction to the rotating plate 35, and the wire W is wound again. The present invention relates to a taker.

[Action]

When exchanging the bobbin, the rotating mechanism 45 rotates the grip mechanism 33 through the rotating plate 35 in the direction opposite to the rotating direction of the bobbin 3, and during the rotation, the grip mechanism 33 causes the traverse mechanism 5 and the bobbin 3 to rotate. Between the grip mechanism 33 and the bobbin 3 by rotating the wire rod W while holding the wire rod W between them.
The wire W between and is cut to temporarily stop the rotation of the grip mechanism 33, the bobbin is taken out in the meantime, and the wire W is further pulled out from the traverse mechanism 5 side by the further rotation of the rotating plate 35. When the bobbin 3 is rotated to a position where it can be held in the gap S formed between the base side surfaces and the line restraining body 30, the rotation of the rotating plate 35 and the grip mechanism 33 is stopped, and the new bobbin 3 is inserted. When the wire rod W is inserted and held by the winding mechanism 2 by the holding mechanism 4, the wire W is sandwiched between the base side surfaces of the bobbin 3 and the wire restraining body 30.

In this state, the rotating plate 35 is further rotated to rotate the grip mechanism 33, and when the wire rod release mechanism 44 is placed, the wire rod W held by the operation of the wire rod release mechanism 44 is released to start. Return to the position. At this time, the new bobbin 3 holding the wire W by the wire restraining body 30 rotates again in the direction opposite to the rotating plate 35, and the winding of the wire W is started.
