When a stationery object (e.g., device or material) is blocking certain beams during normal operation, these beams can be deactivated to enable operation of the press.
Function
3 modes of Blanking Function
1. Fixed Blanking Mode
Multiple optical-axes interrupted area can be set as blanking area (up to 5 areas)
2. Fixed blanking mode with permissible optical axis
It is possible to move the monitoring area up to ± 1 optical axis above or below the fixed blanking setting area.
*When using allowable optical axis function
Even in the above case, It is possible to continue work without interference when blocking certain beams within the permissible optical axes range.
3. Combination of Fixed Blanking and Floating Blanking
When part of the equipment or workpiece is present in the sensor monitoring area, safe work is possible by blanking setting the corresponding area optical axes. It can correspond not only to fixed parts but also to movable parts.
Here is the point !
Visualize monitoring area and blanking area with LED display of dedicated control box
The front panel of the Blanking dedicated control box shows the state of the sensor’s total optical axes.
The LED display can grasp which part of the area is set blanking at a glance.
Blanking area easy to setup
Easy blanking is possible by using only the key switch in the dedicated control box.
*Regarding the blanking setting key, please manage by the administrator such as press work chief administrator.
Three types of blanking function enable safe and efficient work
- Fixed blanking function
- Fixed blanking function using allowable optical axis
- Blanking function combined protection with floating function
*Setting of mode can be easily changed by using the control box.
Applicable as an effective safety measure for press brake
Not affected by the interference in production, such as the followings.
- Material supply device
- Removal device such as robot
- Ejecting device such as conveyor
- Shooters for ejected materials and scrap
Others
Features
- The highest level safety has been realized based on a failsafe design that utilizes mutual checking performed by two CPUs equipped in the receiver, and redundancy of the signal-processing circuit and output circuit.
* Complies with international standard IEC61496-1/2 and North American standard UL61496-1/2. - The sensor is equipped with a Bypass function and Floating function
- *(Optional control box is required to use some functions）
- Diverse line-up to cope with various operating environments
- Select the optimal safety light curtain according to the installation environment, type of press and work content.
- Error indicator – Check details of errors with a single glance
- The number of lit LEDs indicates the reception status, enabling simple alignment of beams.
- Mounting brackets that significantly reduce influence of vibration
- Mutual interference prevention
Safety Device Selection Criteria (Protective Range)
- Mechanical press:(Die height + Stroke length) or more
- Hydraulic press:(Full daylight range) or more
*Note that the necessary protective range varies according to the installation conditions. - In the case that the top beam height at the time of installation is 1,400mm or less from the floor surface→(Die height + Stroke length + Insufficient length) or more
- In the case that the top beam height at the time of installation is more than 1,700mm from the floor surface
→(Die height + Stroke length – Excess length) or more *Lowest beam position is assumed to be the top surface of the bolster.
