前記杵検査装置１は、制御部（図示せず）によって制御されている。制御部は、例えばパーソナルコンピュータのようなコンピュータシステムにおいて構成されており、長さ測定手段４０、全長測定手段６０及び径測定手段７０から出力される信号に基づいて、底長Ｈ、全長Ｌ、長辺ｄ１、短辺ｄ２および外径Ｄを演算するように構成されている。また、この制御部は、プリンタ（図示せず）を接続することにより、これら測定値を図１０に示すような検査成績書の形式で出力するように構成されてる。さらに、制御部は、杵検査装置１の作動を制御する制御プログラムも内蔵している。   The punch inspection apparatus 1 is controlled by a control unit (not shown). The control unit is configured in a computer system such as a personal computer, for example, and based on signals output from the length measuring unit 40, the total length measuring unit 60, and the diameter measuring unit 70, the base length H, the total length L, and the length. It is configured to calculate the side d1, the short side d2, and the outer diameter D. The control unit is configured to output these measured values in the form of an inspection report as shown in FIG. 10 by connecting a printer (not shown). Further, the control unit also has a built-in control program for controlling the operation of the punch inspection device 1.

前記搬送機構１０は、図３に示すように、杵２を保持するための治具１１が載置された検査テーブル１２と、この検査テーブル１２を往復移動させる電動アクチュエータ１３とから構成されている。このアクチュエータ１３は、サーボモータ１４、ボールねじ（図示せず）、ガイドレール１５およびスライドブロック１６を備えており、スライドブロック１６に取り付けられた検査テーブル１２を所定の位置で停止するように構成あれている。治具１１は、杵２の圧縮端部２ｃを保持するものであり、杵２の先端部２ａを上向きにして直立姿勢で杵２を保持するように構成されている。   As shown in FIG. 3, the transport mechanism 10 includes an inspection table 12 on which a jig 11 for holding the punch 2 is placed, and an electric actuator 13 for reciprocating the inspection table 12. . The actuator 13 includes a servomotor 14, a ball screw (not shown), a guide rail 15, and a slide block 16, and is configured to stop the inspection table 12 attached to the slide block 16 at a predetermined position. ing. The jig 11 holds the compressed end 2c of the punch 2, and is configured to hold the punch 2 in an upright posture with the tip 2a of the punch 2 facing upward.

前記回転手段２０は、図３に示すように、ステッピングモータである。このステッピングモータ２０は、前記検査テーブル１２の底面に配置されており、検査テーブル１２と一体となって移動するように取り付けられている。また、検査テーブル１２には貫通穴（図示せず）が穿設されており、この貫通穴にはステッピングモータ２０の回転軸（図示せず）が挿入されている。そして、ステッピングモータ２０の回転軸は、カップリング２１を介して治具１１に固定されており、治具１１は、ステッピングモータ２０の回転に伴って回転するように構成されている。   The rotating means 20 is a stepping motor as shown in FIG. The stepping motor 20 is disposed on the bottom surface of the inspection table 12 and is mounted so as to move integrally with the inspection table 12. In addition, a through hole (not shown) is formed in the inspection table 12, and a rotation shaft (not shown) of the stepping motor 20 is inserted into the through hole. The rotation shaft of the stepping motor 20 is fixed to the jig 11 via a coupling 21, and the jig 11 is configured to rotate with the rotation of the stepping motor 20.

前記第１の撮像手段３０は、図３に示すように、画像センサ３０であり、杵２の先端部２ａを、照明３１で照らしながら上方から撮像可能な位置に配置されている。この画像センサ３０は、図９に示すように、カメラで杵２の穴部２ｄを捉え、その映像から穴部２ｄの画像的な特徴として中央にある***部２ｅを抽出し、***部２ｅの向きを基準データと比較してその合否を出力するように構成されている。この出力信号に応じてステッピングモータ２０を駆動制御することで、杵２は、回転し、***部２ｅが所定の向きとなった位置で停止する。この例では、基準データは、***部２ｅの向きが杵２の搬送方向と同一となるように設定されている。   As shown in FIG. 3, the first imaging unit 30 is an image sensor 30, and is arranged at a position where the tip 2 a of the punch 2 can be imaged from above while being illuminated by the illumination 31. As shown in FIG. 9, the image sensor 30 captures the hole 2d of the punch 2 with a camera, extracts a central raised portion 2e as an image characteristic of the hole 2d from the image, and extracts the raised portion 2e of the raised portion 2e. The direction is compared with the reference data, and the result is output. By controlling the driving of the stepping motor 20 in accordance with the output signal, the punch 2 rotates and stops at the position where the raised portion 2e is oriented in a predetermined direction. In this example, the reference data is set so that the direction of the raised portion 2e is the same as the transport direction of the punch 2.

前記長さ測定手段４０は、図４に示すように、接触式デジタルセンサであり、接触式デジタルセンサの探針４１を上下動させるための駆動機構であるエアシリンダを内蔵している。接触式デジタルセンサ４０は、杵２の上方に配置されており、探針４１を下降させその先端が穴部２ｄの底面に当接するまでの移動量を測定し、この移動量に基づいて底長Ｈを算出するように構成されている。具体的には、予め基準杵に対する移動量を測定し、これとの差から杵の底長を算出する。   As shown in FIG. 4, the length measuring means 40 is a contact digital sensor, and has a built-in air cylinder which is a drive mechanism for vertically moving a probe 41 of the contact digital sensor. The contact-type digital sensor 40 is arranged above the punch 2. The probe 41 is moved down to measure the amount of movement until the tip comes into contact with the bottom surface of the hole 2d, and the bottom length is determined based on the amount of movement. It is configured to calculate H. Specifically, the amount of movement with respect to the reference punch is measured in advance, and the bottom length of the punch is calculated from the difference.

また、長さ測定手段４０は、図２および図４に示すように、位置調整手段４２によって平面移動可能に設置されており、図７に示すように、接触式デジタルセンサ４０の探針４１が穴部２ｄの底面に対して当接する位置を調整することができる。例えば、穴部２ｄの底面が最も窪んだ位置を測定ポイントＰとしこの底長を測定する場合、***部２ｅから３ｍｍ離れた位置が最も窪んでいるとすれば、この位置に探針４１の先端が当接するよう、位置調整手段４２を調整する。位置調整手段４２は、エアシリンダであり、杵の搬送方向に対し平面視で直交する方向に接触式デジタルセンサ４０の位置を変更するように構成されている。   The length measuring means 40 is installed so as to be movable in a plane by a position adjusting means 42, as shown in FIGS. 2 and 4, and as shown in FIG. The position of contact with the bottom surface of the hole 2d can be adjusted. For example, when the position where the bottom surface of the hole 2d is most depressed is set as the measurement point P and this bottom length is measured, if the position 3 mm away from the raised portion 2e is the most depressed, the tip of the probe 41 is located at this position. The position adjusting means 42 is adjusted so that the contact is made. The position adjusting unit 42 is an air cylinder, and is configured to change the position of the contact digital sensor 40 in a direction orthogonal to the transport direction of the punch in a plan view.

前記第２の撮像手段５０は、図５に示すように、マイクロスコープであり、杵の上方に配置され、照明５１で杵２の穴部２ｄを照らしながら鮮明に撮像するためのものである。その目的は後述する。   As shown in FIG. 5, the second imaging means 50 is a microscope, is arranged above the punch, and serves to clearly capture an image while illuminating the hole 2 d of the punch 2 with the illumination 51. The purpose will be described later.

前記全長測定手段６０は、図６に示すように、基本的に長さ測定手段４０と同様の構成で、杵２の全長を測定するものであるが、相違点としては、当該全長測定手段６０である接触式デジタルセンサ６０に設けられた探針６１の先端面は、杵２の先端面よりも大きく成形されており、探針６１を下降させその先端が杵２の先端面に当接までの移動量を測定し、この移動量に基づいて全長Ｌを算出するように構成されている。   As shown in FIG. 6, the full length measuring means 60 basically measures the entire length of the punch 2 with the same configuration as the length measuring means 40. The tip surface of the probe 61 provided on the contact type digital sensor 60 is formed larger than the tip surface of the punch 2, and the probe 61 is moved down until the tip abuts on the tip surface of the punch 2. Is measured, and the total length L is calculated based on this movement amount.

前記径測定手段７０は、図６に示すように、レーザ光を走査して被測定物である杵２に照射する走査照射部７１と、走査照射部７１に対向して配置され、走査照射部７１から照射されたレーザ光を受光する受光部７２と、受光部７２におけるレーザ光の非入射部分の幅に基づいて外径寸法を測定する外径測定部（図示せず）とから構成される。この径測定手段７０では、走査照射部７１と受光部７２とは、杵２の横方向に配置されており、これらの間に被測定物を位置させ、照射されたレーザ光が杵２の外周により遮光されて受光部７２にレーザ光が入射しない部分が生じることを利用して、被測定物の外径を測定するものである。   As shown in FIG. 6, the diameter measuring means 70 scans a laser beam and irradiates the punch 2, which is an object to be measured, and a scanning irradiation unit 71 The light receiving unit 72 includes a light receiving unit 72 that receives the laser light emitted from the light receiving unit 71 and an outer diameter measuring unit (not shown) that measures an outer diameter dimension based on a width of a non-incident portion of the laser light in the light receiving unit 72. . In this diameter measuring means 70, the scanning irradiation part 71 and the light receiving part 72 are arranged in the lateral direction of the punch 2, the object to be measured is positioned therebetween, and the irradiated laser light is applied to the outer periphery of the punch 2. The outer diameter of the object to be measured is measured by utilizing the fact that a portion where the laser light is not incident on the light receiving section 72 due to the light shielding is generated.

また、前記径測定手段７０は、装置本体の背面側に設けられた昇降機構７３によって昇降するように取り付けてある。この昇降機構７３は、電動アクチュエータであり、杵２の先端部２ａの外径および杵の胴部の外径が測定可能なそれぞれの高さ位置で径測定手段７０を停止するよう昇降作動が制御される。   The diameter measuring means 70 is mounted so as to be moved up and down by an elevating mechanism 73 provided on the back side of the apparatus main body. The elevating mechanism 73 is an electric actuator, and the elevating operation is controlled so as to stop the diameter measuring means 70 at each height position where the outer diameter of the tip 2a of the punch 2 and the outer diameter of the trunk of the punch can be measured. Is done.

このような構成の検査装置１を用いて、杵２の各部の寸法を測定する場合を説明する。まず、基準杵を使って、第１の撮像手段３０、長さ測定手段４０、第２の撮像手段５０、全長測定手段６０及び外径測定手段７０を較正する。長さ測定手段４０の較正では、接触式デジタルセンサ４０の探針４１が、穴部２ｄの底面に対し所定位置に当接するよう位置調整手段４２を調整する。例えば、図７および図９に示すように、***部から３ｍｍ横方向へずれた位置が測定ポイントＰになるよう調整する。   A case where the dimensions of each part of the punch 2 are measured using the inspection apparatus 1 having such a configuration will be described. First, the first imaging unit 30, the length measurement unit 40, the second imaging unit 50, the total length measurement unit 60, and the outer diameter measurement unit 70 are calibrated using a reference punch. In the calibration of the length measuring means 40, the position adjusting means 42 is adjusted so that the probe 41 of the contact type digital sensor 40 comes into contact with a predetermined position with respect to the bottom surface of the hole 2d. For example, as shown in FIGS. 7 and 9, the measurement point P is adjusted so that a position shifted by 3 mm in the lateral direction from the protruding portion becomes the measurement point P.

まず、杵２は、先端部２ａを上に向けて圧縮端部２ｃが治具１１で保持され、この状態で測定開始スイッチ（図示せず）を操作して測定を開始すると、検査テーブル１２が移動することにより、第１の撮像手段３０の下方位置まで搬送され、静止する。すると、回転手段２０が駆動し、杵２が回転する。回転中の穴部２ｄの平面を第１の撮像手段３０が撮像し、***部２ｅの向きが杵の搬送方向と同一なったことを捉えると、回転手段２０の駆動が停止する。   First, the punch 2 has the compressed end 2c held by the jig 11 with the tip 2a facing upward. When the measurement is started by operating the measurement start switch (not shown) in this state, the inspection table 12 By moving, it is transported to a position below the first imaging unit 30 and stands still. Then, the rotating means 20 is driven, and the punch 2 is rotated. When the first imaging unit 30 captures an image of the plane of the rotating hole 2d and captures that the direction of the protrusion 2e is the same as the transport direction of the punch, the driving of the rotation unit 20 is stopped.

杵２の位置決めが完了すると、検査テーブル１２が移動することにより、杵２は、長さ測定手段４０の下方の位置まで搬送され、停止する。すると、接触式デジタルセンサ４０の探針４１が、エアシリンダの駆動により、穴部２ｄへ向かって下降し、底面の測定ポイントＰに当接したとき停止する。この移動量に基づいて底長Ｈを算出する。   When the positioning of the punch 2 is completed, the inspection table 12 moves, so that the punch 2 is transported to a position below the length measuring means 40 and stops. Then, the probe 41 of the contact digital sensor 40 is lowered toward the hole 2d by driving the air cylinder, and stops when it comes into contact with the measurement point P on the bottom surface. The base length H is calculated based on this movement amount.

杵２の底長Ｈの測定が完了すると、検査テーブル１２が移動することにより、杵２は、第２の撮像手段５０の下方の位置まで搬送され、停止する。すると、第２の撮像手段５０が、杵２の穴部２ｄの平面を撮像する。この画像データは、図１０に示すように、寸法データとともに検査成績書に添付され、こうすることで検査中の杵に対する打痕等の有無を保証することに役立てられる。なお、第２の撮像手段５０を排除し、第１の撮像手段３０で上記画像データを取得するように構成してもよい。   When the measurement of the bottom length H of the punch 2 is completed, the inspection table 12 moves, so that the punch 2 is transported to a position below the second imaging unit 50 and stopped. Then, the second imaging means 50 images the plane of the hole 2 d of the punch 2. As shown in FIG. 10, this image data is attached to the inspection report together with the dimension data, and this is useful for guaranteeing the presence or absence of a dent or the like on the punch under inspection. Note that the second imaging unit 50 may be eliminated, and the first imaging unit 30 may acquire the image data.

杵２の穴部の撮像が完了すると、検査テーブル１２が移動することにより、杵２は、全長測定手段６０の下方の位置まで搬送され停止する。すると、接触式デジタルセンサ６０の探針６１が、エアシリンダの駆動により、杵２の先端部２ａへ向かって下降し、先端面に当接したとき停止する。この移動量に基づいて全長Ｌを算出する。   When the imaging of the hole of the punch 2 is completed, the inspection table 12 moves, so that the punch 2 is transported to a position below the full length measuring means 60 and stopped. Then, the probe 61 of the contact type digital sensor 60 is lowered toward the tip 2a of the punch 2 by driving the air cylinder, and stops when it comes into contact with the tip surface. The total length L is calculated based on this movement amount.

杵２の全長Ｌの測定が完了すると、同位置で径測定手段７０による測定が行われる。まず、昇降機構７３が作動することにより、走査照射部７１と受光部７２は、杵２の先端部２ａの外径を測定可能な位置へ上昇し、静止する。そして、回転手段２０が駆動し、杵２が回転する。回転中の杵２の先端部２ａに、走査照射部７１からレーザ光が照射されると、杵２の先端部２ａを横断するように走査される。この結果、杵２の先端部２ａで遮光されたレーザ光は受光部７２に到達しないので、受光部７２には走査されたレーザ光が不連続となる部分が生じる。この不連続部分つまりレーザ光を受光しなかった部分の最大値および最小値を測定し、この値に基づいて、先端部２ａの外径として長辺ｄ１及び短辺ｄ２を算出する。この後、昇降機構７３が作動し、走査照射部７１と受光部７２を杵の胴部２ｂの外径Ｄを測定可能な位置まで下降させる。そして、回転中の杵２の胴部２ｂに走査照射部７１からレーザ光が照射されると、杵２の胴部２ｂを横断するように走査される。この結果、杵２の胴部２ｂで遮光されたレーザ光は受光部７２に到達しないので、受光部７２には走査されたレーザ光が、胴部２ｂの外径Ｄの真円度に応じて不連続となる部分が生じる。この不連続部分つまりレーザ光を受光しなかった部分の平均値を測定し、この値に基づいて、胴部２ｂの外径Ｄを算出する。径測定手段７０による検査が完了すると、検査は終了し、杵２は、搬送機構１０の駆動により検査テーブルが復路を移動し、元の位置に戻される。   When the measurement of the entire length L of the punch 2 is completed, the measurement by the diameter measuring means 70 is performed at the same position. First, when the elevating mechanism 73 operates, the scanning irradiation unit 71 and the light receiving unit 72 rise to a position where the outer diameter of the tip 2a of the punch 2 can be measured and stop. Then, the rotating means 20 is driven, and the punch 2 is rotated. When the tip 2a of the rotating punch 2 is irradiated with laser light from the scanning irradiation unit 71, the tip 2a of the punch 2 is scanned so as to cross the tip 2a. As a result, since the laser light shielded by the tip 2a of the punch 2 does not reach the light receiving section 72, a portion where the scanned laser light is discontinuous occurs in the light receiving section 72. The maximum value and the minimum value of the discontinuous portion, that is, the portion not receiving the laser beam are measured, and the long side d1 and the short side d2 are calculated as the outer diameter of the tip 2a based on the measured values. Thereafter, the elevating mechanism 73 operates to lower the scanning irradiation unit 71 and the light receiving unit 72 to a position where the outer diameter D of the trunk 2b of the punch can be measured. When a laser beam is emitted from the scanning irradiation unit 71 to the body 2b of the rotating punch 2, the scanning is performed so as to cross the body 2b of the punch 2. As a result, since the laser light shielded by the body 2b of the punch 2 does not reach the light receiving section 72, the scanned laser light is applied to the light receiving section 72 in accordance with the roundness of the outer diameter D of the body 2b. A discontinuous portion occurs. The average value of the discontinuous portion, that is, the portion not receiving the laser beam is measured, and based on this value, the outer diameter D of the trunk portion 2b is calculated. When the inspection by the diameter measuring means 70 is completed, the inspection is completed, and the punch 2 is returned to its original position by moving the inspection table on the return path by driving the transport mechanism 10.

このように、搬送テーブル１２の停止位置と、長さ測定手段４０の探針４１の平面位置置とを変更することによって、穴部２ｄの底面について所望の位置を測定ポイントＰに設定することができる。このため、穴部２ｄが複雑な形状の杵であっても、杵２の底長Ｈを測定することが可能となる。また、回転中の杵２の先端部２ａにレーザ光を照射して外径Ｄを測定するので、楕円形状の先端部の長辺と短辺を１回転の間で測定することが可能となる。   In this way, by changing the stop position of the transport table 12 and the plane position of the probe 41 of the length measuring means 40, a desired position on the bottom surface of the hole 2d can be set as the measurement point P. it can. For this reason, even if the hole 2d has a complicated shape, the bottom length H of the punch 2 can be measured. In addition, since the outer diameter D is measured by irradiating the tip 2a of the rotating punch 2 with a laser beam, it is possible to measure the long side and the short side of the elliptical tip within one rotation. .
