This invention relates to a method and device for automatically detecting buckling.

で、缶の軸方向に大きな荷重のかかることがある。[Prior art J] In the manufacturing process of canned goods, there is a process of wrapping one lid around the can body, a process of forming a flange on the mouth of an empty can with the lid wrapped tightly, or In the process of performing neck-in processing and flange processing on the mouth of the DI can, which has an integrally formed moat and can body, and in the second seaming process, which is performed after filling these empty cans with contents, A large load may be applied in the axial direction of the can.

In addition, in the neck-in processing of DI cans, the mouth of the can is squeezed inward while applying a load in the axial direction using a drawing machine. At the same time, the mouth of the can is opened outward.

したがって、座屈化を検出して、長毎と選別する必要が
あるが、座屈化の最も大きな欠点である美観の損失につ
いての判断が感覚的なものであること、および自動的な
検出手段として適当なものがないことから、従来は人間
の目視によって座屈化の検出先行なっていた。For this reason, can bodies often buckle during the FRR packaging manufacturing process. Canned goods with buckled can bodies have poor aesthetics, significantly diminishing product value, and can lead to poor sealing. This was a major cause of poor sealing of canned goods. In addition, due to the phenomenon in which a portion of the can H protrudes due to buckling, there is a drawback that one can gets clogged during transportation during the can manufacturing process.6 Therefore, buckling can be detected and sorted by length. However, because the biggest disadvantage of buckling is the loss of aesthetic appearance, it is a sensory process, and there is no suitable automatic means of detection, so conventionally human visual inspection has been used. This led to the detection of buckling.
［解決すべき問題点］

難であるとともに、検査の自動化、ひいては１缶詰製造
工程の自動化を図る上で大きな問題があった。[Problems to be Solved] As described above, conventional buckled seedling detection was performed by human visual inspection. For this reason, there are problems in that there are variations in the criteria for determining whether buckling occurs or not, and high-accuracy detection cannot be expected because it is important to avoid human detection errors due to worker fatigue or carelessness. Ta. In addition, with visual inspection by workers, it is difficult to speed up the inspection, and there are also major problems in automating the inspection and, by extension, automating the process of manufacturing one can.
また、座屈化を自動的に検査する手段として。Also, as a means of automatically inspecting for buckling.
缶の周面に近接センサを複数個並列して設け、これらの
センサで検出した検出信号の値を予め設定してある値と
比較し、不一致の場合に座屈化として判別するようにし
た構成のものが考えられる。A configuration in which a plurality of proximity sensors are arranged in parallel around the circumference of the can, and the value of the detection signal detected by these sensors is compared with a preset value, and if there is a discrepancy, it is determined as buckling. The following are possible.
しかしながら、このような構成の座屈苗検出手段では、
検出精度向上のためにセンサを高密度に配置した場合、
互いのセンサが干渉してしまい誤動作を生じる虞れがあ
る。However, in the buckled seedling detection means with such a configuration,
When sensors are placed densely to improve detection accuracy,
There is a risk that the sensors may interfere with each other and cause malfunction.

ンサの周波数を違えて設定しなければならず、信号処理
が煩雑となり、装置も複雑かつ高価になる欠点がある。For example, if a so-called oscillation type sensor that oscillates a high frequency is used as a proximity sensor, the high frequencies emitted from each sensor will interfere with each other, and to prevent this, the frequency of each sensor must be set differently. However, the signal processing becomes complicated and the device becomes complicated and expensive.

サ間に隔壁を設けなければならず、結果的に高密度な配
置は実現できないという欠点がある。In addition, when using optical sensors, the light beams emitted from each sensor interfere with each other, and to prevent this, it is necessary to install a partition between each sensor, resulting in a high-density arrangement. The drawback is that it cannot be done.
