Counting overlapping printed materials
Individual printed materials that overlap during transfer can be counted. Simply detecting objects by peak height is unstable because they can move up and down during transfer. The CDX has a height‑difference measurement function that outputs the difference between the current value and the measurement value before a specified number of sampling times. With this function, objects can be counted stably without being influenced by up‑and‑down movement, because the height differences of overlapping objects can be extracted. Even when print patterns have extreme changes in reflectance, such as from white to black, measurement can be carried out without failures or response delays thanks to our in-house‑developed ATMOS image sensor.
How to count
● Displacement sensor CDX: Output data of ②−①, ③−②, ④−③…⑫−⑪● Controller CDA-DM2: Outputs (counts) when the height difference exceeds the preset threshold.In the example on the left, output occurs at ②−①, ⑤−④, ⑧−⑦, and ⑪−⑩, where the height differences is large (i.e., where the boxes overlap).
