Riken Optech - RBS(PSDI) Function

- Optional functions for RBS type devices designed to elevate labor efficiency and safety also have acquired the official approval of the Ministry of Health, Labor and Welfare of Japan.
1. Movable Guards
The movable guard not only will reduce the time required to exchange dies, confirm the safety, and resume formal work but also will improve the overall safety of the press machine.
2. Three-Optical-Axes Floating Blanking Function is available.
This is an optional item for enhancing the function of the light curtain used for processing long strip work-pieces with pass the sensing field of the light curtain. Press machines will not be stopped even when up to three optical axes are interrupted. When four optical axes are interrupted, the press machine will be forcibly stopped.

4. Riken Optech - Safety Laser Scanner sensor for safety area (RS-4)

RIKEN OPTECH_Laser Scanner(RS4)-www.tjsolution.com

Riken Optech model RS-4 Laser scanner safety sensor, it performs continuous scanning over the wide range of 190 degrees covering the entire operating range and if an object or person happens to enter the protective area, it outputs a stop signal. The specifications of this equipment conform to the Type 3, IEC61496-3 Standards. Therefore, it is best suited for safety-related uses. The area sensor with high sensitivity and high resolution has wide-ranging applications. RS-4 is best suited for the protection of humans from mobile systems and static systems requiring safety measures up to the extent of the EN954-1 Type 3 Standards.

- Four Protection Areas are Programmable
Areas can randomly be set with the radius of 4 meters for the protection of humans or for an area with the radius of 15 meters for the detection of objects.

RIKEN OPTECH_Laser Scanner(RS4)_Scan area


- Setting up the Protective Area. There are two ways to set the protective area.

1. Directly inputting the data from a PC
As a rectangular area by using numerical data.
2. Learning functions
Make an outline of a protective area out of cardboard and place it before this equipment. The read-in process starts when the learning function command is executed. The device will scan the outline of the cardboard. A new protective area will be decided based on the data acquired. It also has a function to store the parameters into the database.
