Description

[Detailed description of the invention] [Industrial field of application] The invention is based on a rotating shaft that is inserted through a drum having flanges at both ends of the drum around which the wire is wound, and one flange consisting of radial flange pieces. The present invention relates to a wire winding machine that takes out the wire wound around the body by folding down each flange piece.

[Conventional technology and its problems]

This type of wire winder is shown in Japanese Utility Model Publication No. 35-4517, and will be explained with reference to FIGS. 1 and 2. One flange 1 of the drum A is fixed to the rotating shaft 2, The shell 3 is composed of shell pieces 3a divided in the circumferential direction, and the other flange 4 is composed of radial flange pieces 4 corresponding to each of the shell pieces 3a in the circumferential direction.
The base end of each of the flange pieces 4a is bendably attached to the sliding boss 5 which is slidably inserted into the rotating shaft 2, and both ends of each body piece 3a are attached to the one flange 1. and is bendably connected to the corresponding flange piece 4a.

This winding machine has a sliding boss 5 as shown by the solid line in the figure.
, and raise the flange piece 4a to remove the drum A.
By the rotation of the rotating shaft 2, the filament is wound around the body 3 of the drum A, while the wound filament moves the sliding boss 5 in the opposite direction, and as shown by the chain line in the figure, the filament is wound around the flange. Fold down the piece 4a and take it out from the body 3.

During wire winding in this action, the flange piece 4a
It is necessary to maintain the rotating shaft 2 in an upright state, and this conventional holding means is achieved by fitting a bolt threaded through the sliding boss 5 into the rotating shaft 2 by screwing the bolt. However, this screwing is troublesome and causes a decrease in work efficiency.

[Purpose of invention]

The present invention has been made with the above points in mind, and an object of the present invention is to make it possible to raise the flange piece with a single touch.

[Means to achieve the purpose]

In order to achieve the above purpose, in this invention,
In the well-known wire winding machine described above, a circular locking shaft that partially intersects the rotating shaft is rotatably inserted into the sliding boss, and the rotating shaft is inserted into the locking shaft at the intersection. A recess is formed that is movable in the axial direction, and on the other hand, a locking recess is formed on the rotating shaft into which the circumferential portion of the locking shaft can be inserted when each flange piece stands up to form a flange. In addition, the locking shaft is provided with a torsion spring that always urges the hollow portion to be removed from the circumferential surface of the rotating shaft.

[Effect]

The wire winding machine configured in this way rotates the locking shaft against the torsion spring to align the hollow part with the rotating shaft, and moves the sliding boss to raise the flange piece as in the conventional method. let When this flange piece is erected, the hollow part of the rotating shaft corresponds to the locking shaft, so when the locking shaft is released, the locking shaft fits into the hollow part due to the torsion spring, preventing the sliding boss from moving. be done. That is, the flange piece is maintained in an upright state.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

The main parts of this embodiment are the same as those of the wire winding machine described above, and the explanation thereof will be omitted.

As shown in FIGS. 3 to 5, a circular locking shaft 6 that partially intersects the rotating shaft 2 is rotatably inserted into the sliding boss 5 of the winding machine, and a locking shaft 6 at the intersection is inserted into the sliding boss 5 of the winding machine. A recess 7 is formed in the stop shaft 6 so that the rotary shaft 2 can move in its axial direction. Further, a torsion spring 8 is provided on the protruding portion of the locking shaft 6, and this spring 8 allows the locking shaft 6 to always move away from the rotating shaft 2 with the hollow portion 7 facing upward. Using the handle 9, the locking shaft 6 is rotated against the spring 8, and the sliding boss 5 is moved onto the rotating shaft 2 via the hollow portion 7.

On the other hand, the rotating shaft 2 is formed with a locking recess 10, which the locking shaft 6 faces when the sliding boss 5 is moved and the flange piece 4a is erected to form the drum A. The locking shaft 6 is fitted into the recess 10 by a spring 8 to prevent the sliding boss 5 from moving. That is, the flange piece 4a is maintained in an upright state.

The embodiment is configured as described above, and its operation will be explained next.

First, as shown in FIG. 2, in a state where the flange pieces 4a are erected to form the drum A, the rotating shaft 2 is rotated by a drive machine, or the handles of the flanges 1 and 4 (reference numerals in FIG. 2) are rotated. 11), the drum A is rotated to wind the filament.

When the volume is full, turn the locking shaft 6 to close the recess 7.
is opposed to the rotating shaft 2, the sliding boss 5 is moved to fold down the flange piece 4a as shown in FIG. 1, and the winding is taken out using the tilted body piece 3a and flange piece 4a as guides.

After taking it out, when the sliding boss 5 is moved to stand up the flange piece 4a, the locking shaft 6 is rotated by the spring 8 and fitted into the recess 10, preventing the sliding boss 5 from moving. The assembled state of the drum A shown by the solid line in FIG. 2 is maintained. After this, the process moves to the above-mentioned winding process.

[Effect of idea]

The present invention is constructed as described above, and the movement of the sliding boss is enabled or prevented by engaging and disengaging the rotating shaft and the locking shaft, so this action can be performed with a single touch, improving work efficiency. do.
