【０００１】
【発明の属する技術分野】
本発明は、電気銅製造ラインの最終工程における製品検査に関し、詳しくは、電気銅を所定枚数パイリングした電気銅パイルの外形寸法検査方法および装置に関する。
【０００２】
【従来の技術】
電気銅は、銅鉱石を溶解精製し、これを板状の鋳銅材（粗銅）として鋳造し、この粗銅をアノード（陽極）とし、別に用意したカソード（陰極）板と交互に電解槽に一定間隔で並べて装入し、カソード板に電気銅を析出堆積することで製造される。
【０００３】
このようにして製造された電気銅の外観形状を図３に示す。電気銅１は、略１ｍ四方、厚さ10〜20mmの板であり、前述の電解槽での処理のため、吊り手２が取り付けられている。
この電気銅を出荷するに際しては、20枚程度の所定枚数を客先の指定に応じてパイリングし、電気銅パイルとして出荷する。
【０００４】
電気銅の外観検査は、通常の製造ラインの中で行われる為、前述のように電気銅パイルの状態にて検査が行われる。検査内容は、板間をのぞき込み板間に粒塊がないことを目視検査する。さらに、板の間隔あるいはその累積高さなどを目測して検査基準と比較して電気銅パイルの合否判定が行われる。
【０００５】
【発明が解決しようとする課題】
従来、この電気銅パイルの外観検査は、もっぱら作業員の目視という官能検査に頼っており、そのため検査に時間を要していた。
特に、電気銅枚数が少ないパイルの生産が集中する場合は、操業時間が長引き、ひいては電槽の通電開始が遅れるなど、生産性の低下を招くこともあった。
【０００６】
本発明は、外観検査を作業員による板間の目視検査あるいはパイル高さの目視検査ではなく、パイルの外形寸法で判定をするきわめて検出精度に優れ、また迅速な電気銅パイルの外形寸法検査方法および装置を提供することで以上の課題を解決するものである。
【０００８】
【課題を解決するための手段】
本発明は、電気銅の銅板をパイリングした電気銅パイルのパイル形状を検査する電気銅パイルの外形寸法検査方法および装置であって、該電気銅パイルの各コーナー部の高さを測定し、測定した吊り手側２個所のコーナー部高さをａ、ｂ、測定した反対側２個所のコーナー部高さをｃ、ｄとし、測定した各コーナー部高さａ、ｂ、ｃ、ｄが許容高さ未満であり、かつ、下記不等式を両方満たすとき、迅速に該電気銅パイルの品質を合格と判定するようにして上記課題を解決したのである。
記
｜ａ−ｂ｜＜吊り手側同士の許容差
min （ａ，ｂ）− max （ｃ，ｄ）＞吊り手側の低い方と反対側の高い方との許容差
【０００９】
【発明の実施の形態】
電気銅が正常にパイリングされた良品パイルの側面図を図４（ａ）に示す。一方、図４（ｂ）は、粒塊５がある場合の不良パイルの側面図である。
図４では、20mm厚の電気銅１が５枚パイリングされ、ベース３に載荷された状態が例示されている。電気銅１には、それぞれ吊り手２が取り付けられているため、図示のように１枚づつ傾きをもってパイリングされることになる。
【００１０】
図４には、電気銅パイル上面の任意に設定した基準線４からの距離を例示している。良品パイルである（ａ）の場合は、吊り手２側の基準線４からの距離は、120mm であり、その反対側の距離は160mm となっている。しかし、パイルの間に粒塊５が挟み込まれた不良パイルでは、それぞれ110mm 、100mm となり、パイルの吊り手と反対側の高さも良品パイルの100mm に対して、160mm となっている。
【００１１】
このようにして、挟み込まれた粒塊によって電気銅パイルの高さが変わってくることから、電気銅パイルの高さ管理をすることで挟み込まれた粒塊の有無を知ることができ、電気銅パイルの品質の良不良が判定できる。
ただし、すでに説明したように、電気銅パイルの吊り手側端部とその反対側端部とで幾分高さが異なることに注意が必要である。
【００１２】
電気銅パイルの高さ管理は、この吊り手側端部とその反対側端部の２個所の高さを管理することで実現できる。つまり、図２の高さｂ（又はａ）と高さｃ（又はｄ）を管理することで良不良の判定が行える。具体的には、高さｂ（又はａ）の許容限界位置の直上と、高さｃ（又はｄ）の許容限界位置の直上にビームが通るようにそれぞれ在荷検出装置である光電センサを配置し、それらのセンサが遮光されるかどうかで良不良の判定を行うのである。
【００１３】
更に厳密に良不良の判定を行うためには、図２のＡ〜Ｄそれぞれのコーナー部高さを独立に測定するようにしても良い。具体的には、Ａ〜Ｄそれぞれのコーナー部の直上にレーザ距離計を設け、それぞれのレーザ距離計で各コーナー部までの距離測定を行うのである。
この場合、得られた距離測定値ａ〜ｄがある設定された許容高さ以下、かつ、それぞれの差が設定された許容差以下であるときにパイル形状すなわちパイルされた電気銅の品質を良とする。
【００１４】
この合格判定ロジックの一例を次に示す。
得られた距離測定値をａ〜ｄとして、
（ａorｂorｃorｄ）＜620mm …（１）
｜ａ−ｂ｜＜20mm …（２）
min（ａ，ｂ）−max （ｃ，ｄ）＞10mm …（３）
の判定を行う。 ただし、上記（１）〜（３）式で示した寸法値は、ある一例を示す例示であり、電気銅パイルの仕様毎に異なる値とされる。また、高さについてはパイル高さを直接測定してもよいし、基準点からパイル上端の距離を測定して演算でパイル高さを間接的に測定してもよく、どちらでもよい。
【００１５】
そして、（１）〜（３）式をいずれも満足する場合にそのパイルを良と判定する。また、このいずれかの条件式を外れる場合は、そのパイルは不良と判定される。
【００１６】
さらに詳細に電気銅パイルの形状判定を行うためには、一次元ラインセンサ、画像センサ等を適用して電気銅パイル側面の計測を行い、図２に示すb1、b2、b3とc1、c2、c3の端点をそれぞれ抽出して電気銅１枚毎の隙間測定を行うようにしても良い。このようにすることで、きわめて精密に電気銅パイルの良不良判定を行うことができるようになる。
【００１７】
【実施例】
図１に、本発明の電気銅パイルの外形寸法検査装置を示す。（ａ）は平面図であり、（ｂ）は正面図である。
電気銅パイル1aの高さ方向の許容高さ限界位置直上にビームが通るように光電センサ11a 、11b と11d 、11c が設置されている。図１（ｂ）では、紙面の反対側に電気銅１の吊り手２があり、そのため、光電センサも11d 、11c の設置高さの方が11a 、11b の設置高さより幾分高くなっている。ここで、光電センサ11a 、11b 、11c 、11d はそれぞれ支柱14に固設されている。
【００１８】
また、レーザ距離計12a 、12b 、12c 、12d が梁13に固設され、電気銅パイル上面の各コーナー部までの距離を測定するように配置されている。ここで、図１（ａ）においては、図を見やすくするため、梁13の記載を省略している。15は、外形寸法検査装置の判定処理等を行う制御盤である。
電気銅パイル1aは、搬送ラインを搬送されてきて、本発明の外形寸法検査装置に載荷される。そして、まず光電センサ11a 、11b と11d 、11c で測定が行われ、不良と判定されたときに、更に、各コーナー部のレーザ距離計12a 、12b 、12c 、12d で詳細な判定が行われ、最終的な合否判定がされる。
【００１９】
ここで、光電センサによる判定と、レーザ距離計による判定は、いずれかのみを行うようにしても良く、簡便には、光電センサによる判定だけを行うようにしても良い。
【００２０】

本発明によって、電気銅製造ラインの省力化および生産性向上を達成することができた。

BACKGROUND OF THE INVENTION
The present invention relates to a product inspection in a final process of an electrolytic copper production line, and more particularly to an external dimension inspection method and apparatus for an electrolytic copper pile obtained by piling a predetermined number of electrolytic copper.
[0002]
[Prior art]
For electrolytic copper, copper ore is dissolved and refined, cast into a plate-shaped cast copper material (crude copper), and this crude copper is used as an anode (anode). It is manufactured by charging side by side and depositing electrolytic copper on the cathode plate.
[0003]
The external shape of the electrolytic copper manufactured in this way is shown in FIG. The electric copper 1 is a plate of approximately 1 m square and a thickness of 10 to 20 mm, and a hanger 2 is attached for processing in the above-described electrolytic cell.
When this electrolytic copper is shipped, a predetermined number of about 20 sheets are piled according to the customer's designation and shipped as an electrolytic copper pile.
[0004]
Since the appearance inspection of the electrolytic copper is performed in a normal production line, the inspection is performed in the state of the electrolytic copper pile as described above. The inspection content is a visual inspection of the absence of agglomerates between the plates by looking between the plates. Furthermore, pass / fail judgment of the electrolytic copper pile is performed by measuring the distance between the plates or the accumulated height thereof and comparing with the inspection standard.
[0005]
[Problems to be solved by the invention]
Conventionally, the appearance inspection of this electric copper pile has relied solely on the sensory inspection of the operator's visual inspection, and therefore it took time for the inspection.
In particular, when the production of piles with a small number of electrolytic coppers is concentrated, the operation time may be prolonged and the start of energization of the battery case may be delayed.
[0006]
The present invention is not a visual inspection between plates or a visual inspection of pile height by an operator, but a method of inspecting the external dimensions of an electric copper pile that is extremely excellent in detection accuracy and makes a determination based on the external dimensions of the pile. And the above-mentioned subject is solved by providing a device.
[0008]
[Means for Solving the Problems]
The present invention provides a Dimensions inspection method and apparatus for electrolytic copper pile for inspecting the pile shape of copper pile was piling the copper of the copper plate, to measure the height of each corner portion of the copper pile, measured The heights of the two corners of the suspended side are a and b, the heights of the corners of the two opposite sides are c and d, and the measured corner heights a, b, c and d are allowable heights. less than is, and when satisfying both of the following inequalities is had to solve the above problems and quickly to be judged to be acceptable the quality of the electrolytic copper pile.
Record
| A-b | <Tolerance on the suspension side
min (a, b) −max (c, d)> Tolerance between lower one on the suspension side and higher one on the opposite side
DETAILED DESCRIPTION OF THE INVENTION
FIG. 4A shows a side view of a good pile in which electrolytic copper is normally piled. On the other hand, FIG. 4B is a side view of a defective pile in the case where there are the agglomerates 5.
FIG. 4 illustrates a state in which five pieces of 20 mm-thick electrolytic copper 1 are piled and loaded on the base 3. Since the suspensions 2 are attached to the electric coppers 1 respectively, they are piled up one by one as shown in the drawing.
[0010]
FIG. 4 illustrates the distance from the arbitrarily set reference line 4 on the upper surface of the electric copper pile. In the case of (a), which is a good pile, the distance from the reference line 4 on the hand 2 side is 120 mm, and the distance on the opposite side is 160 mm. However, defective piles in which the agglomerates 5 are sandwiched between piles are 110 mm and 100 mm, respectively, and the height on the opposite side of the pile suspension is 160 mm compared to 100 mm for good piles.
[0011]
In this way, since the height of the electrolytic copper pile changes depending on the sandwiched agglomerates, it is possible to know the presence or absence of sandwiched agglomerates by controlling the height of the electrical copper pile. The quality of pile can be judged.
However, as already explained, it should be noted that the height of the end portion on the suspension side and the opposite end portion of the electric copper pile are somewhat different.
[0012]
The height management of the electric copper pile can be realized by managing the heights of the two ends of the end portion on the suspension side and the opposite end portion. That is, it is possible to determine good or bad by managing the height b (or a) and the height c (or d) in FIG. Specifically, a photoelectric sensor, which is a load detection device, is arranged so that the beam passes directly above the allowable limit position of height b (or a) and directly above the allowable limit position of height c (or d). Whether the sensors are shielded from light or not is determined as good or bad .
[0013]
Furthermore, in order to make a strict judgment of good or bad, the heights of the corner portions A to D in FIG. 2 may be measured independently. Specifically, a laser distance meter is provided immediately above each corner portion of A to D, and the distance to each corner portion is measured with each laser distance meter.
In this case, when the obtained distance measurement values a to d are not more than a set allowable height and each difference is not more than a set tolerance, the pile shape, that is, the quality of the piled electrolytic copper is good. And
[0014]
An example of this pass determination logic is shown below.
The obtained distance measurement values are a to d,
(A or b or c or d) <620mm (1)
| A−b | <20 mm (2)
min (a, b) -max (c, d)> 10 mm (3)
Judgment is made. However, the dimension value shown by said Formula (1)-(3) is an illustration which shows a certain example, and is taken as a different value for every specification of an electrical copper pile. As for the height, the pile height may be directly measured, or the distance from the reference point to the top edge of the pile may be measured, and the pile height may be indirectly measured by calculation.
[0015]
And when all (1)-(3) formulas are satisfied, the pile is determined to be good. If any of these conditional expressions is not satisfied, the pile is determined to be defective .
[0016]
In order to determine the shape of the electrical copper pile in more detail, the side surface of the electrical copper pile is measured by applying a one-dimensional line sensor, an image sensor, etc., and b 1 , b 2 , b 3 and c shown in FIG. The end points of 1 , c 2 , and c 3 may be extracted to measure the gap for each piece of electrolytic copper. By doing in this way, it becomes possible to determine the quality of the electric copper pile with high precision.
[0017]
【Example】
FIG. 1 shows an apparatus for inspecting the external dimensions of an electric copper pile according to the present invention. (A) is a top view, (b) is a front view.
Photoelectric sensors 11a, 11b and 11d, 11c are installed so that the beam passes immediately above the allowable height limit position in the height direction of the electric copper pile 1a. In FIG. 1 (b), there is a suspender 2 of copper 1 on the opposite side of the paper, so that the installed height of the photoelectric sensors 11d and 11c is somewhat higher than the installed height of 11a and 11b. . Here, the photoelectric sensors 11a, 11b, 11c, and 11d are fixed to the column 14, respectively.
[0018]
Laser distance meters 12a, 12b, 12c and 12d are fixed to the beam 13 and are arranged so as to measure the distances to the corners on the upper surface of the electric copper pile. Here, in FIG. 1A, the description of the beam 13 is omitted for easy understanding of the drawing. Reference numeral 15 denotes a control panel that performs determination processing and the like of the external dimension inspection apparatus.
The electric copper pile 1a has been transported along the transport line and is loaded on the external dimension inspection apparatus of the present invention. First, measurements are performed by the photoelectric sensors 11a, 11b and 11d, 11c, and when it is determined to be defective, further detailed determination is performed by the laser distance meters 12a, 12b, 12c, 12d at each corner, A final pass / fail decision is made.
[0019]
Here, the determination by the photoelectric sensor and the determination by the laser distance meter may be performed only, or simply the determination by the photoelectric sensor may be performed.
[0020]
