特開平３−８６１９号(特願平１−１４２３６２号)、「チップ自動分離送給装置」
本装置Ａ２は、図４に示すように、ローター１の各凹部１ａに吸気口８を開口すると共に、フィダー３からローター１の凹部１ａへのチップｔ移乗位置、即ち、設定位置における凹部１ａと相対して位置したフィダー３の先端位置に、設定寸法自在に備えたピン１２とセンサー１１の光通過孔１０を列設して、フィダー１の先頭のチップｔの凹部１ａ内への吸引移乗によるセンサー１１の光線の遮断（ＯＦＦ）→通過（ＯＮ）の検知と連係して、ローター１の１ステップ回転、停止及びピン１２の出、入を制御するようにしたものであり、
【０００５】
フィダー３の先頭のチップｔを突出したピン１２で停止し、その間にローター１が１ステップ回転し、停止して、次位の凹部１ａがフィダー３の相対位置に停止し、
【０００６】
次の瞬間、ピン１２を没入してチップｔを解放すると、該チップｔが凹部１ａの吸気口８の吸気力で凹部１ａ内に吸引移乗支持され、その吸引移乗の過程で光通過孔１０を通過しているセンサー１１の光線が遮断（ＯＦＦ）→通過（ＯＮ）され、
【０００７】
該センサー１１のＯＦＦ→ＯＮ検知で、ピン１２が突出して先頭のチップｔを停止し、また、ローター１の１ステップ回転→停止して、チップｔを移乗支持した凹部１ａの１ステップ搬送と同時に次位の凹部１ａを相対位置に停止することが行われ、
【０００８】
次の瞬間に、ピン１２が没入し先頭のチップを解放して、上記００１１項の状態となり、以下、この作用を繰り返して、ローター１の各凹部１ａに次々とチップｔを分離移乗支持して搬送するものである。
【０００９】
然るところ、本装置のように、出入自在に備えた金属ピン１２によってチップｔの停止、解放を行うようにした場合、ピンとチップの接触やタイミングずれによる衝突などでチップを損傷、破損することが偶々発生し、また、チップが固いセラミックであるため、ピンの方を摩耗、損傷して、比較的短期間の交換を必要とする欠点があり、また、ピンの出入作動用の精密複雑な機構を要してコスト高となる等の課題があった。

【従来例２】
特開平２−２７０７１７号(特願平１−９２３２６号)、発明の名称「チップ自動分離送給装置」
本装置Ａ１は、図３に示すようにローター１の各凹部１ａに吸気口８を開口すると共に、フィダー３からローター１の凹部１ａへのチップｔ移乗位置、即ち設定位置における凹部１ａと相対して位置したフィダー３の先端位置に吸着エアーの吸気口９とセンサー１１の光通過孔１０を列設して、フィダー３の先頭のチップｔの凹部１ａ内への吸引移乗によるセンサー１１の光線の遮断（ＯＦＦ）→通過（ＯＮ）の検知と連係して、ローター１の１ステップ回転、停止及び吸気口９の吸気、停止を制御するようにしたものであり、

【００１３】
該センサー１１のＯＦＦ→ＯＮ検知で、吸気口９の吸気を開始して先頭のチップｔを吸着支持し、ローター１が１ステップ回転→停止して、チップを移乗支持した凹部１ａの１ステップ搬送と同時に次位の凹部１ａを相対位置に停止することが行われ、

次の瞬間に、吸気口９が吸気を停止しチップを解放して、上記０００５項の状態となり、以下、この作用を繰り返して、ローター１の各凹部１ａに次々とチップｔを分離移乗支持して搬送するものである。
【００１５】
然るところ、本装置のように先頭のチップｔを吸気口９の吸気力で停止支持するようにした場合、チップｔの底面に吸気による吸着力を全チップにつき均一有効に作用させることが、チップ底面及びフィダー面の平面の整合が不同不均一であるため、中々難しく、また、吸気を開始してから吸気力がチップ底面に作用してチップを停止するまでに時間を要すると共に、該作用時間を高速精密に調整することが困難である等の問題があった。

In the present invention, when one row of chips (various small electronic components) conveyed by a feeder is separated and transferred to each recess for supporting a chip of a rotor that rotates intermittently at high speed, one of the chips is transferred. Provided is an automatic chip separation / conveying device capable of performing addressing / separation transfer at high speed and accurately.
[0002]
[Previous issues]
Conventionally (see FIG. 2), chips t (chips in an as-manufactured state) are put into the ball feeder 2 and conveyed in the circumferential direction by vibration, and aligned in a single line on the single-line conveying path 2a on the outer periphery. Next, this is transferred to the feeder 3 for linearly moving in one row, separated from the leading tip t of the feeder 3 by one, and transferred one after another to each recess 1a for supporting the tip of the rotor 1, During the conveyance process by the high-speed intermittent rotation of the rotor 1, various inspections are performed by the inspection means 4, and the defective chip t is removed from the rotor 1 by the removal means 5, and the front / back reversing means 7 is turned front or back as necessary. Only the non-defective chip t that has been prepared and passed the measurement is transferred to a chip tape (illustrated example), chip cassette or other chip holding means 6, the chip holding means 6 is set in various chip mounting devices, and the chip is printed on a printed circuit board.

Japanese Patent Application Laid-Open No. 3-8619 ( Japanese Patent Application No. 1-142362 ) , “Automatic Chip Separating and Feeding Device”
As shown in FIG. 4, the apparatus A2 opens the intake port 8 in each recess 1a of the rotor 1 and also inserts the tip t from the feeder 3 into the recess 1a of the rotor 1, that is, the recess 1a at the set position. By the pin 12 and the light passage hole 10 of the sensor 11 that are provided to be freely set at the front end position of the feeder 3 that is positioned relative to each other, the suction tip transfer into the recess 1a of the tip t of the feeder 1 is performed. In conjunction with detection of light blocking (OFF) → passing (ON) of the sensor 11, the one-step rotation and stop of the rotor 1 and the exit and entry of the pin 12 are controlled.
[0005]
The leading tip t of the feeder 3 is stopped by the projecting pin 12, and the rotor 1 rotates one step during that time, stops, and the next concave portion 1 a stops at the relative position of the feeder 3,
[0006]
At the next moment, when the pin 12 is inserted and the tip t is released, the tip t is sucked and transferred into the recess 1a by the suction force of the suction port 8 of the recess 1a, and the light passage hole 10 is moved in the suction transfer process. The light beam of the sensor 11 passing through is blocked (OFF) → passed (ON),
[0007]
When the sensor 11 is turned OFF → ON, the pin 12 protrudes to stop the leading chip t, and the rotor 1 rotates one step → stops simultaneously with the one-step conveyance of the recess 1a that supports the transfer of the chip t. The next recess 1a is stopped at the relative position,
[0008]
At the next moment, the pin 12 is immersed and the leading tip is released, and the state of the above-mentioned item 0011 is reached. Thereafter, this action is repeated, and the tip t is separated and transferred to each recess 1a of the rotor 1 one after another. It is to be transported.
[0009]
However, when the tip t is stopped and released by the metal pin 12 that can be freely inserted and removed as in this apparatus, the tip may be damaged or broken due to contact between the tip and the tip or collision due to timing deviation. Occurs by chance, and the tip is made of hard ceramic, so there is a drawback that the pin is worn and damaged, requiring a relatively short period of replacement, and the precision of the pin entry / exit operation is complicated. There was a problem that a mechanism was required and the cost was high.

[Conventional example 2]
Japanese Patent Application Laid-Open No. 2-270717 ( Japanese Patent Application No. 1-92326 ) , title of invention “Automatic chip separation and feeding device”
As shown in FIG. 3, the apparatus A1 opens the intake port 8 in each recess 1a of the rotor 1, and faces the tip t transfer position from the feeder 3 to the recess 1a of the rotor 1, that is, the recess 1a at the set position. The suction port 9 of the suction air and the light passage hole 10 of the sensor 11 are arranged in a row at the front end position of the feeder 3 that is positioned in the position, and the light of the sensor 11 is transferred by suction transfer into the recess 1a of the tip t of the feeder 3 In conjunction with detection of cut-off (OFF) → passage (ON), one-step rotation and stop of the rotor 1 and intake and stop of the intake port 9 are controlled.
[0011]
The leading tip t of the feeder 3 is sucked and stopped by the suction force of the suction port 9, during which the rotor 1 rotates one step and stops, and the next concave portion 1 a stops at the relative position of the feeder 3.
[0012]
When the suction of the intake port is stopped at the next moment and the tip t is released, the tip t is supported by suction transfer into the recess 1a by the suction force of the suction port 8 of the recess 1a. The light beam of the sensor 11 passing through 10 is blocked (OFF) → passed (ON),
[0013]
When the sensor 11 is turned OFF → ON, intake of the air inlet 9 is started and the leading chip t is sucked and supported, and the rotor 1 is rotated by one step → stopped, and the concave portion 1a carrying the chip is supported by one step. At the same time, the next recess 1a is stopped at the relative position,
[0014]
At the next moment, the intake port 9 stops intake and releases the tip, and the state of the above-mentioned 0005 is reached. Thereafter, this action is repeated to support the transfer of the tip t one after another in each recess 1a of the rotor 1. Transported.
[0015]
However, when the leading tip t is stopped and supported by the suction force of the suction port 9 as in this apparatus, the suction force by suction is applied to the bottom surface of the tip t uniformly and effectively on all the chips. The alignment between the chip bottom surface and the feeder surface is uneven and uneven, so it is difficult. In addition, it takes time for the suction force to act on the chip bottom surface and stop the chip after the intake starts. There was a problem that it was difficult to adjust the time precisely at high speed.

A stop air blowing port 13 is provided at a position just before the light passage hole 10 of the sensor 11 at the tip position of the feeder 3 and immediately before the tip of the tip t of the feeder 3 . ,
[0025]
In conjunction with the detection (OFF) and passage (ON) detection of the light beam of the sensor 11 by suction transfer of the leading tip t of the feeder 3 into the recess 1a of the rotor 1, the rotor 1 is rotated by one step, stopped, Further, the leading tip t and the following tip t are moved forward and stopped by the ejection of the stop air from the air outlet 13, and the leading tip t is sucked and transferred into the concave portion 1a of the rotor 1 and the trailing tip t is moved forward by the stop of the blowing of the stop air. This is an automatic chip separation / conveying device A in which one chip t is separated from the feeder 3 and transferred to and supported by the respective recesses 1a of the rotor 1 in order and conveyed by the rotation of the rotor 1.
[0026]
In the apparatus A, the feeder 3 installed at a position relative to the concave portion 1a of the rotor 1 at the set position conveys the chips t straightly in a line, and blows forward the leading chip t and the subsequent chip t at the tip. stopped at the stop air jet from the mouth 13, the top head of the chip t and subsequent chip t is intended chips t vibration conveying force is accumulated in a state of pressing press closely spaced, and at the stop of該噴air the chip t is obtained a connection chip t so as to move forward by releasing the stop state after with sucking ERROR into the recess 1a of the rotor 1.
[0027]
Further, the air jet hole 13 and the light passage hole 10 are arranged on the center line of the feeder 3, and the light passage hole 10 has a through hole or, as in the illustrated example, a permeable plastic or the like in the through hole. Are closely fitted so that the light beam of the sensor can pass through.
[0028]
[Action]
It stops at stop air injection gas for jetting advancement of the head of the chip t and subsequent chip t in the feeder 3 from the jet ports 13 immediately before the position of the tip of the chip t, rotor 1 is rotated by one step in between, stop Then, the next concave portion 1a stops at the relative position of the feeder 3 ((A) in FIG. 1).
[0029]
At the next moment, when the squirting of the squirting port 13 is stopped and the leading tip t is released from the forward stop state , the leading tip t is supported by suction transfer into the recess 1a by the suction force of the suction port 8 of the recess 1a. passes through the light transmitting hole 10 over the course of the suction ERROR, Rutotomoni is ray blocking sensor 11 passing through the same hole 10 (OFF) → passage (ON), the subsequent chip t is advanced, (FIG. (I) → (B))
[0030]
In OFF → ON detection of the sensor 11, and squirting the stop air just in front of the chip t starting to destination mind jet of jet ports 13 to stop the advance and, rotor 1 is one step rotation → Stop Then, simultaneously with the one-step conveyance of the concave portion 1a supporting the transfer of the chip t, the next concave portion 1a is stopped at the relative position,
[0031]
At the next moment, the squirting port 13 stops squirting and releases the tip t, so that the initial state is obtained (FIG. (B) → (b)). Thereafter, this action is repeated, and each recess 1a of the rotor 1 is repeated. One after another, the chips t are separated and transferred and supported.

【effect】
Unlike the conventional example 1 ( Japanese Patent Laid-Open No. 3-8619 ) , the present application is different from the case of using a pin that can be freely moved in and out. Since the tip is stopped and released with air, there is no risk of damaging the tip, and there is no need to wear or replace like a pin. A complicated and precise control mechanism is unnecessary, and there is an excellent feature that can save money by that amount.
[0033]
Unlike the case of prior art 2 ( Japanese Patent Laid-Open No. 2-270717 ) , in which the leading tip is stopped by the suction force of the suction port, the present application ejects from the air outlet to a position immediately before the tip of the leading tip. Tip advancement is momentarily stopped by stop air jetting, that is, when stop air is jetted at high speed instantaneously from the jet port to the position just before the tip of the top tip, the stop air is stopped. It acts in the same way as a pin, and has an excellent effect that the tip of the leading tip collides with the stop air and can stop the advance of the tip instantly and accurately.
In addition, there is an effect that the fuze from the fumarole is stopped and the stop state of the chip can be released instantaneously at high speed.
[0034]
As in Conventional Example 3 ( Act No. 59-170014 ( Act No. 61-83620 ) Microfilm ) , the air nozzle located just above the workpiece is blown onto the upper surface of the workpiece itself. With this means, the workpiece is pressed against the chute wall with that pressure, and the workpiece's advancement is stopped with its frictional resistance, and the effect of stopping and releasing the tip advancement instantaneously and accurately is demonstrated. can not, but the present application, by ejecting the Sutoppue earth fast momentarily just in front of the front end portion of the forefront chip from jet ports, stop air acts like the stopper pin, the head of the tip end portion is the stop There is an excellent effect that the forward movement of the chip can be instantaneously and accurately stopped by colliding with air.
[0035]
Conventional Example 4 ( Japanese Patent Laid-Open No. 1-92119 ) uses the air blown from the jet outlet as an air flow to flow out from the product passage toward the conveyance path, and blows the air flow toward the front of the product to advance the air. Although regulated, there is a problem that this means cannot exhibit the effect of stopping the advance of the chip accurately and reliably in an instant.
In this regard, the present application is such that the stop air acts like a stopper pin by instantaneously ejecting stop air from the air outlet to a position immediately before the tip of the leading tip, so that the tip of the leading tip is stopped. By colliding with air, the problem can be solved by stopping the advance of the chip instantly and accurately.
