  Next, the operation of the coil wire support device according to the present invention configured as described above will be described.

  First, the starting end of the coil wire A supported on the free rotating cable base 3 is placed horizontally through the drawing machine 7, the pinch roll 6, the straightening machine 5, and the outlet side brush 27 arranged on the outlet side of the free rotating cable base 3. The coil wire A is clamped by a wire rod supply mechanism provided on the side of the forging machine, and the coil wire A is intermittently pulled out by a predetermined length while being rotated by the free rotating wire base 3 and supplied to the forging station. Here, at the normal time when the coil wire A is supported on the side surface of the cylindrical support 12, the stretcher 7 does not perform the stretching operation and is located at a fixed position and acts as a simple guide roller.

  When the coil wire A on the free rotating wire platform 3 becomes a terminal by use, the final terminal of the coil wire A passes through the pressing bar 16 and the pressing bar 16 comes into contact with the side surface of the cylindrical support 12. Become. At this time, this is detected by a detection mechanism (not shown) such as a sensor, the air cylinder (not shown) is shortened, the pressing operation by the pressing bar 16 is released, and the free rotation line as shown by the solid line in FIG. It moves to the standby position 2b of the cylindrical casing 2 provided radially outward from the outer periphery of the table 3. At the timing when the pressing bar 16 returns to the standby position, the lift cylinder 8 is extended by a signal from a detection mechanism (not shown) such as a sensor to raise the lift plate 4 to the position of the imaginary line shown in FIG. Lift the end of the coil wire A to the height of the stretcher. Then, the stretcher 7 operates in synchronism with the intermittent supply operation of the coil wire A in the raised state, and as shown in FIG. 4, the slide body 22, that is, the cylindrical casing of the stretch roller 23 The terminal of the coil wire A is stretched by repeating the reciprocating movement outwardly with respect to 2. As a result, the end of the coil wire curled by the curl is forcibly stretched and then smoothly fed into the pinch roll 6 and the straightening machine 7 without any trouble. As a result, the coil wire A can be smoothly and smoothly sent to the straightening device 7 via the pinch roll 6 and the pinch roll 6 to the terminal, and the number of discarded terminals of the coil wire A can be reduced as much as possible, resulting in material loss and cost.

When the moving support body 17b is positioned at the horizontal use position, the straightening machine 5, the pinch roll 6, and the stretching machine 7 are arranged in the horizontal state on the lower side of the swinging support body 17b. The straightening roll 5, the pinch roll 6, and the stretcher 7 can be arranged neatly with little installation space in the upper position on the outlet side of the coil wire A of the cylindrical casing 2. In addition, for example, when the distance between the pair of correction rolls 5a... 5a is adjusted according to the wire diameter of the coil wire A to be used, the position of the swing support 17b can be changed from the horizontal use position to the inverted retreat position. That is, it is possible to change the positions of the correction rolls 5a... 5a paired in the horizontal direction at the time of use so as to form a pair in the vertical direction. Thereby, although the straightening machine 5 is arranged at an upper position near the coil wire A exit of the cylindrical casing 2, the operator enters between the installation member 17 and the cylindrical casing 2 and stands up from the front. Thus, the clearance adjustment between the straightening rolls 5a... 5a paired in the vertical direction can be easily and accurately performed. Furthermore, not only the adjustment of the gap between the straightening rolls 5a... 5a, but also the replacement of the straightening rolls 5a. Of course, it can be easily performed.

  Further, on the bottom of the cylindrical casing 2 is a truncated cone-shaped bottom surface portion 2c that receives bonde powder scattered from the surface of the coil wire A and falling from the gap of the free rotating wire platform 3, and the outer periphery of the bottom surface portion. An annular groove portion 2d to be formed and a suction port 2e for a vacuum cleaner for discharging the bond powder that has fallen and accumulated in the annular groove portion 2d are formed. Since the cleaning brush 28 is provided so as to drop the bond powder that has fallen along the inclined surface of the bottom surface portion 2c into the annular groove portion 2d, the surface of the coil wire A can be obtained by feeding the coil wire A or the like. The bond powder scattered from the bottom of the cylindrical casing 2 is positively received by the inclined surface of the truncated cone-shaped bottom surface portion 2c, and the bond powder that has fallen on the inclined surface of the coil wire A Withdrawal The cleaning brush provided to a free lower portion of this by utilizing the inclined surface of rotation of the rotary line table 3 and the bottom surface portion 2c due to, automatically and can be efficiently dropped into the annular groove 2e of the cylindrical casing. As a result, the bonder powder in the annular groove 2e is easily and quickly sucked out from the cleaner suction port 2f for discharging the bonder powder provided in the annular groove 2e through the vacuum cleaner. The bottom can be cleaned.

  In the straightening machine 5 of the above-described embodiment, the number of the straightening rolls 5a is five, but the number of straightening rolls 5a is appropriately increased as shown by, for example, the phantom line in FIG. Of course, it may be performed accurately. FIG. 8 shows another embodiment in which the horizontal guide roll 27 is attached to the front lower position of the stretching roller 23 and the pressing roller 24 in the above-described stretching machine 7 so as to be orthogonal to the coil wire supply direction. It is. The horizontal guide roll 27 always guides the coil wire so that it passes between the stretching roller 23 and the pressing roller 24. In FIG. 8, it is configured such that it cantilever freely supports the pressing roller 24 side, but it can also be provided on the stretching roller 23 side.
