DISCLOSURE OF THE INVENTION The problem to be solved by the present invention is to provide a unwinding method and a device thereof having a payout rotary arm, in which a conventional payout device is used without using an expensive control device and power. It is an object of the present invention to provide a method and a device for automatically switching between two reels simply and inexpensively by using the unwinding device using a rotating arm as it is.

[0008]

In order to achieve the above object, the present invention has the following constitution. That is, the first aspect of the present invention is, in the wire unwinding method of the unwinding rotary arm system, with respect to the rotary shaft extending from the support base,
A reel shaft is provided on both sides, and reels A and B each having a wire wound thereon are attached to each reel shaft, and a winding start portion of the wire in the reel A to which the wire is first wound is attached. And Lee
The wire at the winding end portion of the reel B is joined with a wire having a fixed length, and a sensor for detecting the end of the wire unwinding in the first reel A is provided, and the rotation is performed by the operation of this sensor. The shaft is unlocked, the rotary shaft is rotated, the reel B is moved to the position of the reel A, the rotary shaft is locked again, and the rotary arm continues from the reel B. The present invention relates to an automatic wire unwinding switching method characterized by unwinding the wire.

The rotating shaft is installed so as to be slightly inclined toward the reel A side with respect to the vertical direction, and the rotating shaft is naturally rotated by the weight difference between the reel A and the reel B. This is an unwinding automatic switching method, and the storage line of a fixed length of wire is the automatic switching method which is the length of time required for switching the reel A and the reel B.

A second aspect of the present invention is a payout rotary arm type unwinding device having two or more reel shafts, which is a stopper for fixing the rotation of a support base for supporting the reel shafts. A tool, a wire-storing jig for storing the wire ends wound around two reels, and a releasing jig for releasing the fixing of the stopper,
The reel shaft on the side of the feeding rotary arm is the reel on the opposite side.
It relates to an automatic wire unwinding switching device characterized in that a stand of a reel shaft support is installed so as to be inclined with respect to a horizontal plane and is inclined with respect to a horizontal plane.

More specifically, the releasing device is a dropper arranged above the beam supported by one fulcrum in a balance shape, the jig for holding and guiding the wire, and the stopper for fixing the support base. It is an automatic wire unwinding device comprising a jig and having a portion for suspending a dropping jig at one end of a beam and a portion for arranging a wire at the other end.

[0012]

The basic idea of the automatic wire unwinding switching method according to the present invention is to rotate the support for supporting the reel shaft so as to drive the reel A and B for exchanging the reel shaft. By tilting the support base, the height difference and gravity difference between the two reels A and B are used to determine the time when the reels A and B should be exchanged, and the rotation of the reel shaft is fixed. Is performed by using the movement of the wire fed for the processing.

That is, since the wire of the first reel A is unwound for processing, its weight decreases,
When switching to the next reel B, a gravity difference always occurs between the two reel axes. In this way, the unstable state caused by the gravity difference and the height difference between the two reel shafts becomes stable by rotating the rotatable reel shaft support. As described above, the present invention utilizes the force of gravity and does not require a new driving force from the outside, and the
It is possible to rotate the rotary shaft together with the support table in the horizontal plane by half rotation. In the rotating operation described above, the same switching operation can be repeated by replacing the first reel A, which has been half-rotated, with the reel B on which a new wire is wound.

The basic structure of the device for automatically switching the reel of the second invention is as follows. That is, a reel shaft support having two reel shafts, a wire storage jig for storing wire ends wound around the two reels A and B, and rotation of a rotatable support base. The unwinding device is composed of a stopper for fixing and a releasing jig for releasing the stopper, and the pedestal of the supporting table is installed so as to be inclined with respect to the horizontal plane.

The two reel shafts are arranged at positions facing each other around the support column of the support. The support base has a structure that can rotate in a horizontal plane, and individual reel shafts are extended and rotated.
Can be placed at the Also, the support is
A stopper for fixing the position of the reel shaft at the arm position is installed. The pedestal of the support base is installed so as to be inclined with respect to the horizontal plane, and the rail axis on the arm side is set so as to be lowered with respect to the rail axis on the opposite side.

The wire storage jig welds and joins the wires wound around the two reels A and B mounted on the reel shaft, and the wire between the two joined reels A and B is joined. This is a device for storing wires, and a device for storing the amount of wires necessary for continuously feeding the wires during the time required for exchanging the reels A and B.

Next, when a horizontally rotatable support base is fixed by a stopper and the reels A and B are exchanged, a releasing device for releasing the reels is wound around the first reel A. When the processing of the wire is completed and the processing is transferred to the wire of the next reel B, the device has a function of detecting the transfer of the wire and subsequently releasing the fixing of the support base.

As a device having the above-mentioned function, the fixing can be easily released by the following procedure.
That is, such a releasing device has a structure of a beam supported like a balance at one fulcrum, a drop jig is suspended at one end of the beam, and the first reel A is connected to the storage line portion at the other end. Since all the joined wires are suspended and passed over them at a predetermined position and the dropping jig is pushed up to balance, it is possible to control the timing of the fall by passing the wires, and also to stop it. The tool can be released by gravity, and the fixation can be stably released without applying a load such as tension to the wire to be paid out. The dropping jig is arranged above the vertical line of the stopper for fixing the rotation of the support base.
Further, the wire placed at one end of the beam is placed at a predetermined position via a wire gripping guide jig installed near the beam. The predetermined position is set such that the wire held by the wire gripping guide jig presses one end of the beam on which the wire is arranged to lift the drop jig on the opposite side of the beam.

Further, the storage wire jig and the releasing device are arranged so that, when the wire moves to the next reel B, it passes through the releasing device and then moves to the storage wire jig.

At the time of exchanging the reels A and B, the wire stored in the storage jig is unwound for processing so that the reel shaft is rotating, that is, the support base is rotating. To Lee
Since the wire wound around the reel B is not paid out, the reels A and B can be stably exchanged.

The procedure for switching between the two reels A and B using the automatic switching and unwinding device of the second invention having the above structure is as follows. First, the reels A and B in which the wire is wound are mounted on two reel shafts installed in advance on the support base, and the winding start portion of the wire of the first reel A and the next reel. The wire at the winding end of B is joined and joined
The wire between rules A and B stores the required length in the storage wire portion, and then the wire between the first reel A and the storage wire jig is released and fixed via the wire grip guide jig. It is arranged at one end of the beam of the tool, and a fall prevention jig is suspended at the other end.

When the processing of the first wire is completed as the processing of the wire progresses, the unwound wire moves from the first reel A to the next reel B. With the movement of the wire, the wire passes through the wire grip guide jig and then the release jig. Then, when the wire passes through one end of the beam installed in the balance shape, the pressing force by the wire is released, the balance of the balance moves so that the dropping jig is downward, and the dropping jig falls. The dropping jig that has fallen falls on the stopper for rotation of the support base to release the fixed rotation of the support base. Then, the support table, which has been released from the fixed state, is in a rotatable state, but in this state, the weight of the first reel A located in the direction of the rotary feeding arm is large because the wire is processed. It becomes smaller, while the next reel B mounted on the opposite reel shaft will have a greater weight due to the wire being wound.

Since the mount supporting the support is installed so as to be inclined with respect to the horizontal plane so that the position of the support at the position where the feeding arm is located is lowered, the mount is supported with respect to the support. 2 on the feeding rotation arm side and the opposite side
Since the two reel shafts have a height difference, they become unstable due to the weight difference described above, and rotate in the horizontal plane by the action of gravity, and the next reel B reaches the arm position. After the rotation, the rotation stopper provided on the support base operates to fix the rotation. The processing of the wire during the automatic exchange from the first reel A to the next reel B is performed by feeding the wire stored in the storage line portion.
