Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring device by automatic wiring.

[0002]

2. Description of the Related Art As a conventional example of this kind of wiring material supply by automatic wiring, for example, a technique described in Japanese Patent Laid-Open No. 61-117899 is known. FIG. 4 shows a vertical cross section of the supply head according to this conventional example. Reference numerals 13 and 14 in the drawing are correction rollers for correcting the winding curl of the wiring material 15 in the horizontal and vertical directions. This allows
The winding curb removing work in the previous step of the wiring work is omitted, and the shape of the wire rod 15 after wiring is stabilized.

[0003]

However, in the wiring method as described above, when the automatic wiring is performed, the case where the wiring material is supplied to the wiring device in a entangled state is not dealt with, When the entangled wire material is supplied, it is necessary to re-wire the wire material by breaking the wire material. Further, when the supplied wiring material is not supplied to the wiring device due to entanglement or the like, the wiring device has to be stopped, and there is a problem that workability is reduced.

The present invention has been made in order to solve such a problem, and its object is to, when the entanglement of the wiring material is detected, move the wiring head at the end of one operation of the wiring. An object of the present invention is to provide a wiring device that enables efficient automatic wiring by temporarily stopping and restarting after removing the entanglement.

[0005]

In order to achieve the above object, a wiring apparatus according to the present invention has a hole diameter larger than a diameter of a wiring material, and a wiring guide for preventing a entangled wiring material from passing therethrough. , A route in which a movable pulley that loosens the wiring material by its own weight and a pulley guide that guides the movement range of the movable pulley, and in a normal state, the wiring material meanders by a length required to complete one operation of the wiring. And a sensor that detects the entanglement in the wiring guide by detecting the moment when the displacement of the movable section starts, and when the sensor detects the entanglement, It is characterized in that it has a function of buffering the distance required to complete one movement of the line.

[0006]

With the above construction, according to the present invention, even when the wiring material is jammed due to entanglement or the like and is not supplied during the wiring by the automatic wiring, the wiring head travels while pulling out the wiring material as it is. The number of wires will increase, and the wire material will break if left as it is. Therefore, the movable part is displaced with an increase in the tension of the wiring material so that the distance required to complete one operation of the wiring can be buffered, and at the moment when the movable part starts displacement, that is, The state in which the wiring material is entangled is detected using a sensor.

By providing such a entanglement detection sensor in a wiring device for automatic wiring, when the entanglement detection sensor is activated during wiring, the wiring head is temporarily moved when one operation of the wiring is completed. After stopping and repairing the entanglement of the wiring material, it is possible to continue the wiring from the point where the wiring head stopped temporarily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an outline of a wiring device of the present invention, and FIG. 2 shows a wiring pattern and a wiring state. In the above, the wiring head 3 has the XY drive mechanism that can freely travel on the wiring pallet 2, and the case 11
The wiring material 10 led out from the wire passing through the wiring guide 9, the supply pulley 7, the movable portion 12, and the guide pulley 6 for guiding the wiring material led out of the movable portion 12 to the wiring device. It is supplied to the head 3. Then, the wiring head 3 travels on the wiring pallet 2 while hooking the wiring material 10 on the wiring pin 1 to perform wiring with a constant tension. The wiring pins 1 are arranged on the wiring pallet 2 along the wiring pattern.

Since the wiring guide 9 has a hole diameter larger than the diameter of the wiring material 10 and is fed through the wiring material 10 through this hole, the entangled wiring material 10 cannot pass through this hole. There is. The movable portion 12 is composed of a movable pulley 4 and a pulley guide 5, and in the vicinity of the movable portion 12,
A sensor 8 for detecting the moment when the movable portion 12 starts to be displaced is provided. In a normal state, the wiring material 10 is supplied to the wiring head 3 side through a meandering route by the weight of the movable pulley 4, and the arrangement is such that when the movable pulley 4 moves, It is set to a length that can cushion the distance required to complete the operation. Then, the movement of the movable pulley 4 is detected by the sensor 8, which detects the entanglement of the wiring material 10.

Next, the operation of this embodiment will be described with reference to FIG. For the wiring, the wiring head 3 is the wiring bullet 2
This is performed while traveling over and pulling out the wiring material 10 from the case 11. At this time, the wiring material 10 may be pulled out from the case 11 in a entangled state.

Therefore, as shown in FIG. 3A, the wiring material 10 is passed through a wiring guide 9 having a hole diameter larger than the diameter of the wiring material 10 to stop the supply of the entangled wiring material 10. However, also in this case, the wiring head 3 continues to run, and the wiring material 10 is pulled out from the tip of the wiring head 3, so that the tension of the wiring material 10 increases, and this tension causes the movable pulley 4 to move to the pulley guide. Follow 5 and move up in the drawing.

The moment of displacement of the movable pulley 4 is detected by the sensor 8 and a temporary stop command is sent to the wiring head 3. Then, as shown in FIG. 3B, the wiring head 3 is moved to the next wiring pin 1 (wiring 1 operation) and then temporarily stopped. In this way, after removing the entanglement of the wiring material 10 and the like, the wiring head 2 is made to travel again from the position where it was temporarily stopped, and wiring is continued.

[0013]

As described above, according to the present invention,
In the case of automatic wiring, the wiring device is provided with a means for detecting the entanglement of the wiring material and a means for buffering the distance required to complete one operation of the wiring material. Since the wiring work is temporarily stopped after the completion of one operation of the wire, automatic wiring can be efficiently performed even when the supply of the wiring material is stopped.
