3. Large openings

In addition to considering the dangerous moving parts that people or upper limbs can access through the opening, large openings should also consider the risk of extrusion and shear between the passing product and the opening due to weight or shape factors. A combination of fixed protective devices, interlocking movable protective devices and electrosensitive protective devices is generally adopted to prevent personnel from entering the machine through the equipment opening and coming into contact with dangerous moving parts.

1) Use rotary door with interlock function.

2) Automatic curtain door protection device.

3) Active Photoelectric protection device with pressure sensitive contact (AOPD)

4) Active Photoelectric Protection Device with interlocking rotary door (AOPD)

5) Vertical active Optical protection device (AOPD) for different load widths

6) Active Optical Protection Device (AOPD) with dynamic beam interruption function

7) Use the laser scanner to automatically select the protection device for the effective detection area

The specific safety requirements and application scenarios of different protection methods are described in detail in the standard, such as the fourth type of protection “Active photoelectric protection device with interlocking rotary door (AOPD)” : In order to distinguish between products and people entering the equipment, AOPD with muting function can be installed at the entrance and exit position. In order to prevent the fixed protection of the product and the opening position from causing the risk of extrusion or shearing, rotary doors with interlocking function should be installed on both sides of the entrance. In order to prevent the light curtain from entering the machine with the product during muting, the clearance between the product and the edge of the rotary door should be less than 120mm.

Standard EN 415-10 has made clear safety requirements for the entrances and exits of different sizes of packaging equipment, and only by meeting the relevant safety requirements can personnel be effectively prevented from coming into contact with dangerous moving parts inside the equipment from the opening of the equipment.
