Until
now, Safety light curtains have been regarded as able to improve safety
but unable to contribute to productivity. Nevertheless, in the case of
the RBS type safety devices, their Presence Sensing Device Initiation
(PSDI) system for press allow operators to perform the stamping
processing without having to operate push button switches. The slide
will activate when the operator's hand inserting the material into the
die is removed to the safe area, thus, productivity is improved.
Needless to say that if the ray is shielded by something when the slide
is going down, the slide will stop its motion. Thus, safety can be
secured.
We strongly recommend you use our RBS in your factory. This
revolutionary safety device functions to improve productivity and safety
as well as reduce operator fatigue. |

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.

- |
it makes your stamping work easier.
Operators now don't have to work as vigorously because they don't have to operate push-button-switches. |

- |
It will improve your productivity.
Productivity will be improved as stamping work can be done without operating push-button-switches. |

- |
Operators can use both hands to operate push-button-switches as usual.
Thanks to the adoption of an auxiliary
optical axis, the front guard for the bolster or part of the front guard
can be removed to allow operators to perform their work as usual. |

- |
Measures to bring it close to the intentional activation have been taken.
If a person's hand or arm is going in or out from beyond the scope or from the wrong direction, the slide will not activate. |

- |
The slide will
not activate if the beam has not been interrupted for 0.3 seconds or
more. It assures you of even greater safety than before.
Our original functions, such as the newly
developed light sensor and double CPU with mutual check function
incorporated control box, installed in every unit will assure you of
even greater safety than before. |

- |
A combination of functions of each divided optical axis will prevent malfunctions from occurring
A. |
It detects if a person's hand or arm is going in or out from the upper part of the working range.
If a person's hand or arm is going in or out when the PSDI is being used, the press machine is unable to activate. |
B. |
When the PSDI is being used, a person's
hand or arm going in or out within the operational range for inserting a
hand or arm is deemed as within the scope. |
C. |
When inserting a hand or arm, the press
machine can be activated only when the beam are interrupted in sequence
of B to C. If only C is interrupted, it will be deemed as abnormal
because the action of going in and out has been done from the wrong
direction. |
D. |
It detects a person's hand or arm going in or out from the lower part. |
E. |
If only E is interrupted at the time when the PSDI is being used, it will be deemed as abnormal. |

Protection of dies and prevention of no-load stamping
The work-checking sensor (optional) will
check the presence and the position of work pieces to protect dies from
being damaged by any malfunction and to prevent the press machine from
performing lost motion. In case the work-checking sensor cannot be
installed on the machine, a movable pause button (optional) of the PSDI
can be installed above the bolster. |

Movable guards that facilitate the exchange of dies
We are offering various types of movable
guards including partial open and shut, sliding in front and behind,
opening and shutting on right and left, and rise and fall types. |
