気銅を析出堆積することで製造される。2. Description of the Related Art Copper ore is obtained by dissolving and refining copper ore, casting it as a plate-like cast copper material (blister copper), and using the blister copper as an anode, alternately with a separately prepared cathode (cathode) plate. Is manufactured by depositing and depositing electrolytic copper on the cathode plate at regular intervals in the electrolytic cell.

The inspection contents are visually inspected to see that there is no agglomerate between the plates, except between the plates. Further, the gap between the plates or the cumulative height thereof is visually measured and compared with an inspection standard to determine whether or not the copper copper pile is acceptable.

に、電気銅枚数が少ないパイルの生産が集中する場合

るなど、生産性の低下を招くこともあった。Heretofore, the appearance inspection of the electrolytic copper pile relied solely on the sensory inspection of the operator's visual observation, and it took a long time for the inspection. In particular, when the production of piles with a small number of electrolytic copper is concentrated, the operating time is prolonged, and the start of energization of the battery case is delayed, which may cause a decrease in productivity.

提供することで以上の課題を解決するものである。According to the present invention, the visual inspection is not a visual inspection between plates or a pile height by an operator, but a determination is made based on the external dimensions of the pile. The above problem is solved by providing a dimensional inspection method and apparatus.

The above problem was solved by installing an in-stock detection device at an allowable height limit position of the copper copper pile and quickly determining the copper copper pile that passed the inspection standard by not detecting the presence of the cargo.

When the measured height of each corner of the copper pile is equal to or less than the allowable height, and when the difference between the heights of the corners is equal to or less than the allowable difference, the quality of the copper copper pile is quickly determined to be acceptable. Thus, the above problem was solved.

(B) is a side view of the defective pile in the case where there is a granular mass 5. FIG. 4 illustrates a state in which five pieces of electrolytic copper 1 having a thickness of 20 mm are piled and loaded on the base 3. Since the suspenders 2 are attached to the electrolytic copper 1 respectively, the piles are piled one by one as shown in the figure.

In the case of the non-defective pile (a), the distance from the reference line 4 on the side of the suspender 2 is 120 mm, and the distance on the opposite side is 160 mm. However, in the case of the defective pile in which the agglomerate 5 is sandwiched between the piles, the height is 110 mm and 100 mm, respectively.

ことに注意が必要である。In this way, since the height of the electrolytic copper pile changes depending on the interposed particle mass, the presence or absence of the interposed particle mass can be known by controlling the height of the electrolytic copper pile. In addition, it is possible to judge whether the quality of the electrolytic copper pile is good or bad. However, it should be noted that, as already explained, the height of the end of the electrolytic copper pile on the side of the hanging hand is slightly different from that on the opposite side.

By managing (or d), good or bad can be determined. Specifically, immediately above the allowable limit position of the height b (or a),
The photoelectric sensors serving as the presence detecting devices are arranged so that the beams pass right above the allowable limit position of the height c (or d), and the quality is determined based on whether the sensors are shielded from light. . This is the first embodiment of the present invention.

The heights of the corners of each of A to D in FIG. 2 may be measured independently. Specifically, a laser distance meter is provided immediately above each of the corners A to D, and the distance to each corner is measured by each laser distance meter. In this case, when the obtained distance measurement values a to d are equal to or less than a set allowable height and each difference is equal to or less than the set allowable difference, the pile shape, that is, the quality of the piled copper is improved. And

However, the dimension values shown in the above formulas (1) to (3) are examples showing a certain example, and are different values for each specification of the electrolytic copper pile. Regarding the height, the pile height may be measured directly, or the distance from the reference point to the upper end of the pile may be measured, and the pile height may be measured indirectly by calculation.

In the embodiment described above, a photoelectric sensor or a laser range finder is used as the measuring means. However, the present invention is not limited to these optical sensors, and an ultrasonic type or eddy current type sensor may be used. Needless to say, this may be done. Further, it is also possible to apply a contact type sensor such as a limit bar.
