The safety protection devices of SEPPES pvc roll up door have three kinds:infrared safety photoelectric protection, safety light curtain and bottom side airbag.Many enterprises will have such confusion when purchasing: what is their role?Do our companies need to equip these devices?

In this article, we will discuss the working principle of the safety protection devices and their role, as well as what scenarios are they suitable for, to solve your questions.

Infrared safety photoelectric protection of high speed door

The working principle of the infrared safety photoelectric protection device is based on the emission and reception of infrared light. One side of the device is fitted with a number of infrared transmitting tubes and the other side correspondingly has the same number of infrared receiving tubes. When the infrared signal from the transmitter tubes is blocked, the receiver tubes cannot receive the signal, and the device immediately issues an alarm or controls the mechanical equipment to stop working, thus avoiding safety accidents.

Infrared safety photoelectric protection is the standard configuration of SEPPES high speed door.when there are vehicles, personnel or other obstacles passing by the door, infrared rays are blocked, the door will immediately stop closing or reopen to avoid collision accidents due to the door closing. Especially in workshops, logistics centers and other places where vehicles and personnel come in and out frequently.It can prevent PVC roll up door from pinching pedestrians or hitting vehicles, and protect the safety of the working environment.

Safety light curtain of pvc roll up door

The working principle of the safety light curtain is similar to infrared safety photoelectric protection device, by transmitting infrared rays, generating a protective light curtain, and when the light curtain is blocked, the device sends out a blocking signal, controlling potentially hazardous mechanical equipment to stop working. Safety light curtains than photoelectric add a few more infrared sensing photoelectric, the sensing area increases, safety is also improved.

Light curtains have a very wide range of applications for machining, logistics and warehousing, handling, commercial retailing, office space and so on. For example, in factories that require constant feeding and retrieval of materials, if the operator is required to open and close the door frequently, it not only increases the workload of the operator, but also reduces the production efficiency. In this case, the use of light curtains is the best choice. In addition, when the operator is feeding and retrieving materials, as long as any part of the body to block the light, it will make the rapid door into a safe state without bringing harm to the operator.

Safety bottom edge airbags of fast doors

The airbag includes a transmitting end device and a receiving end device, the transmitting end device includes a pneumatic switch and a transmitting circuit, the airbag bottom seal for triggering the pneumatic switch is mounted at the bottom of the speed door, and the transmitting circuit is triggered when the pneumatic switch is closed.

SEPPES adds airbags to the U-shaped bottom pocket of the door curtain, which is suitable for food processing factories, electronic factories, logistics and warehousing and robotic equipment rooms. When the door descends, if someone or an object passes by, the airbag will be squeezed and deformed, the signal will be sent to the control box, and the door will rise automatically to ensure the safety of the staff or to protect the goods from damage.

These three safety protection devices you can take according to their actual situation, maximize the use of their value, but also to help your own business more efficient and safe operation.
