法もある。 Figure 1 shows an example of a diode transfer device, in which 1 is a diode with a magnetic lead, 2 is
3 is a magnet box that temporarily holds a plurality of diodes 1 in a parallel state by installing a pair of flat magnets 2a and 2b opposite each other; 3 is one end of the magnet box 2; It is a rotating drum that rotates with a portion of the drum encased in the drum, and as shown in FIG.
Magnets 6, 6 that attract 5 are embedded. Reference numeral 7 denotes a chain conveyor that transfers the diodes 1 sent at a constant pitch by the drum 3 and transfers them to the next process at a constant pitch. The diodes 1 that have been soldered are transferred to the next process at a certain pitch by the device shown in FIG. Transfer to process. By the way, as a method for determining the quality of the diode 1 on the drum 3, a sensor (not shown) is installed at a predetermined position near the drum 3 to detect the presence or absence of a lead.
A lever placed between the sensor and the chain conveyor 7 can be detected by detecting defective products such as irregularities or bent wires based on the timing of the detection output of the sensor, or by visually detecting defective products by an operator. (not shown), the defective products are removed and transferred to a magnetic box where only the defective products are stored.
Further, as a means for taking out defective products, there is a method in which an electromagnet is arranged on the drum 3, and the defective diodes are attracted by the electromagnet and transferred to a takeout magnet box.

工程に送られることがあつた。 However, with this device, when the transfer speed is increased,
Not only did the diode 1 that was removed by the lever bounce and not fit properly into the magnetic box for storing defective products, it also jumped onto the good diode 1 and was sent to the next process.

適当であつた。 In addition, if an electromagnet is used to remove a defective diode, it is necessary to stop energizing the electromagnet and completely turn off the magnetism of the electromagnet when transferring it from the electromagnet to the magnet box, which is not suitable for high-speed operation. It was hot.

Structure of the invention: A magnetic box in which a pair of flat magnets are arranged facing each other to hold a shaft-like part having a magnetic lead between the magnets; The electromagnet is characterized in that it includes an electromagnet that detaches the shaft-shaped component and houses it in the magnet box when the strength of the magnetic field reaches a minimum while being energized at half-wave.
ホ 実施例
本考案の一実施例を第3図に示す。同図に於い
て第1図と同一の符号は同一部分を示し説明を省
略する。E. Example An example of the present invention is shown in FIG. In this figure, the same reference numerals as in FIG. 1 indicate the same parts and the explanation will be omitted.
第1図装置と相異するのは、移送体である回転
ドラム3の近傍に不良ダイオード1′を収納する
マグネツトボツクス8を配置し、回転ドラム3の

のみである。なお図示しないが回転ドラム3の近
傍には不良ダイオード1′を検出するセンサが配
置され、電磁石9はセンサの出力に基いて作動す
る。 What is different from the device shown in FIG. 1 is that a magnetic box 8 for storing the defective diode 1' is arranged near the rotating drum 3, which is a transporting body, and moves up and down above the rotating drum 3. The only difference is that an electromagnet 9 that moves between the magnetic boxes 8 is arranged. Although not shown, a sensor for detecting a defective diode 1' is arranged near the rotating drum 3, and the electromagnet 9 is operated based on the output of the sensor.
この電磁石9は所定周波数の半波電流により常
時磁化されている。 This electromagnet 9 is constantly magnetized by a half-wave current of a predetermined frequency.
この動作はセンサがドラム3上の不良ダイオー

オード1′を吸着保持し、上昇してマグネツトボ
ツクス8方向に移動し、ダイオード1′を吸着し
た状態でマグネツトボツクス8内に入り込み、続
けてマグネツトボツクス8から出て、回転ドラム
3上に位置し待機する。 In this operation, when the sensor detects a defective diode 1' on the drum 3, the electromagnet 9 descends, attracts and holds the defective diode 1', rises and moves in the direction of the magnetic box 8, and attracts the diode 1'. It then enters the magnetic box 8, then comes out of the magnetic box 8, and is positioned on the rotating drum 3 to wait.
ここで前記電磁石9がダイオード1′を吸着し
た状態でマグネツトボツクス8内に入り、直ちに
マグネツトボツクス8から出るだけで不良ダイオ
ード1′はマグネツトボツクス内に残留する。 Here, the electromagnet 9 enters the magnetic box 8 while attracting the diode 1', and immediately comes out of the magnetic box 8, leaving the defective diode 1' in the magnetic box.
これは電磁石9に半波電流を供給しているため
常に磁界の強さが変化しているが、電流がゼロの
時でも電磁石9及びリード5の残留磁気により磁

トボツクス8への移動が行われる。そしてマグネ
ツトボツクス8内ではリード5,5はマグネツト
により吸着されるが、この間にも電磁石9が移動
しているため、電磁石9の磁界の強さが最小にな
つた瞬間にリード5,5は電磁石9から離れマグ
ネツトボツクス8内に留まる。そして電磁石9の
磁界が強くなつた時にはダイオード1′との間隔
が離れ、もはや電磁石9には吸着されない。 This is because half-wave current is supplied to the electromagnet 9, so the strength of the magnetic field is constantly changing, but even when the current is zero, the drum remains magnetically attracted due to the residual magnetism of the electromagnet 9 and lead 5. 3 to the magnetic box 8. Inside the magnetic box 8, the leads 5, 5 are attracted by the magnet, but since the electromagnet 9 is also moving during this time, the leads 5, 5 are stopped at the moment when the strength of the magnetic field of the electromagnet 9 reaches its minimum. It leaves the electromagnet 9 and stays inside the magnet box 8. When the magnetic field of the electromagnet 9 becomes stronger, the distance between the diode 1' and the diode 1' increases, and the electromagnet 9 no longer attracts the diode 1'.
そのため電磁石9を連続通電状態で連続動作さ
せても分離がうまくゆく。 Therefore, even if the electromagnet 9 is continuously operated in a continuously energized state, separation is successful.
ここで電磁石9に交流電圧を加えると磁界強さ
が最小の時間が短かくなり分離がうまく行われな
いことがあり、移動速度に追随できないことがあ
る。 If an alternating current voltage is applied to the electromagnet 9, the time when the magnetic field strength is at its minimum becomes shorter, and separation may not be performed well, and it may not be possible to follow the moving speed.
電磁石に供給する半波電流の周期及び電流値は
移動速度やマグネツトボツクス8の磁界強さに応
じ適宜調整すればよい。 The period and current value of the half-wave current supplied to the electromagnet may be adjusted as appropriate depending on the moving speed and the magnetic field strength of the magnet box 8.

Effects of the invention The present invention applies a half-wave current to the electromagnet that takes out the shaft-like parts and moves them to the magnet box, thereby separating the shaft-like parts at high speed and storing them in the magnet box while continuously operating the electromagnet.
