Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention automatically winds a fixed amount of wire onto a bobbin, and then automatically binds the end of the wound wire to a Y-shape to automatically discharge a bobbin wound with the wire. The present invention relates to an automatic binding device for wire rods.

[0002]

2. Description of the Related Art Various automatic winding devices for winding a fixed amount of wire around a bobbin have been proposed and developed. This automatic winding device is equipped with a hook that rotates around the bobbin while hooking the end portion of the wire rod and a cutter that cuts the end portion of the wire rod. It is designed to prevent the end portion of the wound wire rod from unraveling spontaneously, but it is known that the sequence control of such a series of work is performed by a timer or the like. There is.

[0003]

In this automatic winding device, the operating time of the timer is appropriately switched depending on the strength of the inherent tension of the wire itself which is sent out when the wire is hooked while the wire is hooked. Must be changed. That is, for example, when performing Y-binding operation on a wire having a large diameter, a strong load acts on the sending side unless the operating time of the timer is extended to the optimum value. A large tension also acts on the hook to be pulled around, and the hook is cut without the wire reaching the predetermined position, that is, without the wire rod.

Further, for example, in the case of performing a Y-shaped bundling work of thin wire, a weak load acts on the sending side unless the operating time of the timer is shortened to the optimum value. A small tension acts on the hook that draws the wire, and the hook moves beyond a predetermined position. As a result, the wire can be cut with a cutter, but because the hook is stopped below the normal position with respect to the bobbin, that is, it is too close to the bobbin discharge surface, the predetermined wire winding Even if the hook escapes from the mechanism, the hook cannot contact the bobbin discharge surface and move outside. Therefore, in view of the above-mentioned circumstances, the present invention reliably binds the wire after winding and discharges the wire regardless of the thickness of the wire and the tension of the wire. It is an object of the present invention to provide an automatic binding device for wire rods that can be completely automated.

[0005]

That is, according to the present invention, after automatically winding a fixed amount of wire onto a bobbin, the end of the wound wire is hooked, and the wire is wound along the outer periphery of the bobbin. The terminal side of the wire rod is wound while making one revolution, and the Y-shaped binding of the wound wire rod is performed, and the terminal end side of the wound wire rod is already wound around the bobbin. A hook member for bundling to the end side of the wire, a cutter for cutting the wire rod downstream of the Y-bundling portion of the circumferentially wound wire rod after Y-bundling with the hook member, A wire rod automatic binding device having a discharging means for automatically discharging the bobbin in which the wound wire material is cut, the position detecting means for detecting when the hook member has reached a certain position, and the position detection means. Depending on the signal from the means Wherein in which Y-unity and a control section for stopping the circulating operation of the hook member made.

[0006]

According to the present invention, when the position detecting means detects that the hook member has reached a predetermined position, the control section which receives a signal from the position detecting means completes the Y-shaped bundling, and the hook is in a revolving operation. The member can be stopped accurately at a predetermined position. As a result, no matter whether the hook member makes a swiveling motion due to a difference in tension or the like, the hook member does not pull back the wire rod excessively or insufficiently, and the wire rod is bundled at a predetermined position.
The wire can be cut, and the bobbin can be reliably discharged after winding the wire.

The controller 4 (see FIG. 2). Reference numeral 5 in the drawing indicates a bobbin around which the wire rod 6 is wound.

The hook member 1 includes a bobbin 5 and a fixed amount of wire 6
In order to wind the wire rod 6 and to bind the wound wire rod 6 in a Y shape, the rotation force of the motor 8 is transmitted through a predetermined gear and the clutch mechanism 7 and is fixed to the rotating second rotary shaft 11B. In the rotating member 12, the hand member 1 at the tip thereof
It is attached to 2A.

The cutter 2 is attached to the hand member 12A together with the hook member 1 and operates under the control of the control unit 4 so that the wire 6 after Y-binding by the hand member 12A is located downstream of the binding portion. It is designed to be cut with.

The position detecting means 3 is for detecting and confirming the position of the hook member 1 when the Y-shaped binding work is completed, and in this embodiment, an appropriate detecting member 31 fixed to the second rotating shaft 11B. A photo sensor or the like for optically detecting is used. The position detecting means is not particularly limited to the optical means such as the photo sensor, but various types such as a proximity switch can be used.

When the control section 4 receives a predetermined signal output from the position detecting means 3, it immediately outputs a predetermined stop signal to the hook driving section 13 that performs the orbiting operation of the hook member 1 to rotate the hook member 1. The operation is designed to stop correctly at a preset position. Further, the control unit 4 is configured to cause the drive unit 13 of the cutter 2 to output a predetermined operation signal after stopping the revolving operation of the hook member 1. Further, the control unit 4 cuts the wire rod 6 by the cutter 2 and then holds the bobbin discharging means 10, for example, the bobbin 5 from both sides in this embodiment.

When the wire rod winding operation of the predetermined length is completed, the clutch mechanism 7 is operated by the control of the control unit 4, whereby the transmission of the rotational force from the motor 8 to the first rotating shaft 11B is stopped and the wire rod winding is performed. The operation stops. Then, a control unit signal is output from the control unit 4 to the hook drive unit 13, and the rotating member 12 stopped at the predetermined position is activated. As a result, the hook member 1 that rotates around the outer periphery of the bobbin 5 counterclockwise in FIG.
However, the wire 6 is pulled in the same direction while being locked.
Further, a control unit signal is output from the control unit 4 to the hook drive unit 13, and the hand member 12A (hook member 1) stops and then rotates clockwise. As a result, Y-shaped binding is performed. Immediately after this, a control signal is output from the photo sensor of the position detecting means 3 to the hook drive section 13 from the control section 4 which receives this signal, and the operation of the rotating member 12 is stopped. The hook member 1 stops at a predetermined position. Next, a control signal is output from the control unit 4 to the cutter driving unit 21, and the wire rod 6 is cut immediately after the cutter 2 is operated and Y-shaped binding is performed, that is, downstream of the binding portion. Further, a control signal is output from the control unit 4 to the bobbin discharging means 10, and the first rotating shaft 11A that holds the bobbin 5 from both sides retracts, whereby the bobbin 5 is automatically discharged to the outside.
