Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic winding device for a wire, which winds a wire on a pair of bobbins alternately and automatically.

[Conventional technology]

Various automatic winding devices capable of automatically winding a wire on a bobbin have been proposed and developed.

As this automatic winding device, for example, as shown in FIG. 7, a traverser 102 is alternately moved on each bobbin while moving in a body axis direction of each bobbin with respect to a pair of bobbins 100 and 101.
It is known to wind 103. In addition, in the automatic winding device having such a configuration, usually, after the winding of the wire 103 on one bobbin 100 is completed, when switching the winding operation to the other bobbin 101, the sending means 104 operates, and The drawing guide 105 is moved by the sending means 104 and the wire rod 103 is moved.
Is pushed out to a predetermined position (hereinafter referred to as a lockable position), and the claw 10 provided on the rotating body 106 on the other bobbin 101 side is pushed out.
After locking and fixing the wire 103 to 7, the other bobbin
The wire 103 is wound around the wire 101.

[Problem to be solved]

By the way, such an automatic winding device usually has a configuration in which one bobbin is fully loaded with a wire material (hereinafter referred to as full winding) regardless of the position of the rotating body, that is, the rotating body. The feeding means is operated irrespective of the position of the claw in the radial (radial) direction in the above, and the wire pulling guide is moved to push out the wire. Therefore, if the tip of the claw collides with the wire while the wire is traversing the rotation passage area of the claw, the wire may be cut, and if this cutting accident occurs, a great deal of labor and time is required until recovery. Problem.

Therefore, various attempts have been made to prevent such a cutting accident, but no effective solution has been found, and this is a major problem.

The present invention has been made in consideration of the above-described circumstances, and when a wire is locked and fixed to a nail, an automatic winding of the wire that can reliably prevent the occurrence of a cutting accident in which the wire is cut by colliding with a tip end of the nail. It is an object of the present invention to provide a collecting device.

[Means for solving the problem]

That is, the present invention includes a detachable bobbin, and winds the wire on one of the bobbins via a traverser in a state where one end of the wire is locked to a claw of each rotating body driven and rotated by a motor. At the same time, after the wire is fully wound on the one bobbin, the wire drawn from the bobbin is sent out of the other bobbin-side claw by the sending means, and the wire is caught at the next rotation operation of the claw. An automatic winding device that locks a claw on a claw and thereby performs a winding operation on a next bobbin, the detection device including a detection unit that detects a current position of the claw on the rotating body, and the sending unit includes a bobbin. A motor provided separately from the drive, and an extruded body that extrudes a wire while rotating by the motor, and that traverses and passes through the rotation area of the claw, based on a signal output from the detection means, Nail passage Those configured to operate control the delivery means at a predetermined timing until the next pass.

[Action]

In the automatic winding device of the present invention, when one bobbin is fully loaded, the detecting means provided on the other bobbin operates to detect the position of the claw in the rotating body in the radial direction. The control means operates the motor of the sending means at a predetermined timing based on the output signal, in other words, the motor operates at the predetermined timing after the claw passes and until the next passage, and the rotating body rotates. In addition, the wire can be sent out to the lockable position outside the nail without colliding with the nail.

〔Example〕

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

FIG. 1 shows an automatic winding device according to the present invention. The automatic winding device includes a pair of bobbins 2, 3 rotating together with a rotating body 1, a sending means 4, a detecting means 5, And control means (not shown).

In the drawing, reference numeral 6 denotes a wire, and 7 denotes a traverser. The traverser 7 winds the wire 6 evenly over the entire body while moving along the body axis direction of each of the bobbins 2 and 3. It has become.

One rotating pair 1 is provided on each of the bobbins 2 and 3, and a claw 7 that locks the wire 6 in a state where the wire 6 is bitten around the periphery.
Is mounted, and the rotational driving force from the motor 9 is transmitted through a transmission mechanism 10 such as a pulley on the way, and rotates at a constant speed.

The bobbins 2 and 3 are attached to the rotating body 1 in a state where they do not rotate, and are detachable from the rotating body 1 so that the bobbins 2 and 3 can be replaced with the next one when the bobbin becomes full. It has become.

The detecting means 4 checks and detects the current position of the nail 7 in the radial direction on the rotating body 1, and in this embodiment, emits light of a predetermined wavelength (λ) as shown in FIG. It comprises a light emitting section 4a and a light receiving section 4b which emits a predetermined signal when emitted from the light emitting section 4a and reflected by the claw 7, and outputs the signal to the control section 11 (see FIG. 3). It has become.

When one of the bobbins 2 and 3 becomes full and the other bobbin is switched to the other bobbin and the wire 6 is wound, the sending means 5 operates prior to this, and the pawl 7 on the bobbin side to be newly wound is used.
A part of the wire 6 is locked, and in this embodiment, it is constituted by a motor 12 and an extruded body 13. Motor 12
The operation is controlled by the control means 11, and in this embodiment, a step motor is used, which operates every time Δt from the start and rotates the rotary shaft by 2π (rad). As shown in FIG. 4, the extruded body 13 traverses, at a predetermined timing, a danger area β in which the wire 6 may be cut by collision with the wire 6 in the rotation area α in which the claw 8 rotates. The wire 6 is pushed out at a speed higher than the moving speed of the claw 8 and is sent out to a predetermined lockable position (not shown) so that the wire 6 can pass therethrough. That is, the extruded body 13 rotates at a predetermined timing so that the wire 6 traverses and passes through the danger area β within a certain time after the claw 8 has passed through the danger area β and before the next pass. In this embodiment, a substantially bar-shaped member is used as shown in FIG. 5, and it makes one rotation from the uppermost position every time to prepare for the next operation.

The control means 11 operates the motor 12 of the sending means 5 at a predetermined timing based on the signal output from the detecting means 4 to push out the wire 6 by the extruded body 13 and send it out of the claw 8. The wire 6 is controlled so as to be cut by the tip of the claw 8, and a microcomputer is used. That is, as shown in FIG. 3, the control means 11 of this embodiment is configured such that the input side is connected to the output side of the detection means 4 and the output side is the motor of the transmission means 4 and the motor 9 for driving the rotating body 1. Is connected to
