Integration
AKAS SBM® – Safety and protection system for open frame folding machines.
The three-dimensional laser protection field consisting of laser transmitter and receiver protects the clamping area between the upper and lower beam. It serves as protection during the clamping movement. Additional monitoring of the entire safety functions of a folding machine by redundant, dynamic high-speed monitoring according to PL e, Sil 3, safety category 4.
Transmitters
When the upper beam is closed, the laser safety field is progressively blanked out. The system offers protection up to 6 mm opening.
Optional:
With columns for floor mounting
Optional:
human machine interface FE-HMI-DL-F-B for status and error messages and for selecting operating modes such as “box bending function”.
Receiver
The horizontal and vertical laser protection field protects against pinching of limbs when closing the upper beam.
Optional: With columns for floor mounting
The columns are mounted on the floor and the transmitter and receiver can be adapted both vertically and horizontally to the respective machine.
Technology
AKAS® SBM 
Fiessler Elektronik safety solutions for folding machines (SBM) consist of optical safety and a safety controller. The components are CE type tested (c)UL listed and comply with other national and international standards.
Functional principle of optical safety device:
A three-dimensional laser protective field between AKAS® SBM transmitter and AKAS® SBM receiver monitors the clamping area between the upper and lower beam. Due to the special type of beam arrangement, the protection up to the nearest in front of the danger spot.
This eliminates the intermediate stop at 15 mm which would otherwise be necessary.
The result: maximum safety with maximum productivity.
The AKAS® SBM safety solution also offers permanently redundant safety monitoring of all safety-relevant functions of a folding machine.
Flexibility in assembly AKAS ® SBM transmitters and receivers can be individually attached directly to the machine body with the flexible T-slot mounting on 3 sides. Floor mounting is easily possible through the height-adjustable mounting column (SAU_AKAS_SBM).
Safety Functions
Optional:
Protection of the cutting device by a second three-dimensional laser
protection field.
Bending Mode
The right choice for every type of bending
The AKAS® SBM safety system provides the user with three easy-to-select operating modes:
Flat bending mode
The basic mode of the safety system AKAS® SBM is the flat bending mode. In the flat bending mode, the protective field in front of the operator and the vertical protective field directly at the bending line are active. This means that the complete 3-dimensional protective field protects the operator during the complete closing movement of the upper beam.
Box bending mode
The box bending mode is selected by the operator when box-shaped parts
have to be bent. In this operating mode, the front part of the laser safety
field is blanked out for the duration of the box bending stroke. This enables
the upper beam to close without interruption even if the front part of the
protective field is interrupted by the edged sides of a box. The operator is
protected by the vertical protective field on the bending line.
Bending of wavy material
This mode of operation allows the bending of wavy material.
