Detection of Overlapped Outer Packaging Paper

Detection of Overlapped Outer Packaging Paper

The BGS-HDL series can be used to detect the presence of colorful outer packaging paper and whether the papers are overlapped.
The BGS-HDL series’ two control outputs enable simultaneous detection of both the presence of the outer packaging paper and overlapped papers by turning on Output 1 when one sheet is detected, and turning on Output 2 when two or more sheets are detected.
This means that all the work in applications that would conventionally require two sensors can be done with just a single sensor.

Overlap detection of transparent containers

Overlap detection of transparent containers

The DR-Q digital laser transparent object sensor monitors overlapping transparent containers. Generally, detection is based on height. However, if the difference in height is small, or the line contains mixed objects, height-based detection will be difficult.
With the DR-Q, detection of overlapping containers is possible based on even slight differences in receiving light levels. This makes detection possible even with transparent objects, which proved difficult to detect with conventional models.

Detecting overlapping caps for beverage package

Detecting overlapping caps for beverage package

Fiber sensor amplifier D3RF and built-in lens thru-beam type fiber cable NF-TX01 can detect overlapping caps for beverage package because of high power light even if the cap is not transparent.
Controlling, saving setup and restoring setup of each fiber amplifier can be done through CC-Link utilizing communication unit UC1-CL1 connected to Mitsubishi MELSEC-Q/L series efficiently as well.
