In modern manufacturing enterprises, production is no longer limited to a single equipment, independent control mode, but more and more toward the direction of automation, intelligence, systematization. Taking the automobile assembly line as an example, from punching, welding, painting process to assembly line, tens of thousands of parts have to be accurately transported in place and assembled in a short time, which has very high requirements for production process and automatic control. In this case, the requirements of regional environment and production safety of the production line also have to be constantly improved.

Area isolation and security protection

Area between different processes and equipment need professional machinery protection door for isolation, especially between spraying, punching, welding and other related processes. The protection door can be interlocked with the machine - the door can only be opened when the machine stops working, and the machine can only be started after the door is properly closed, so as to protect the stability of the regional environment and the safety of operators to the greatest extent.

Intelligent control by PLC and information exchange in real time

The main difference between machinery protection door and common high speed door is that the door is not worked as an independent individual, but as a part of the production line. The opening and closing of the door is controlled by the equipment PLC system. At the same time, the position status, light grille trigger, system error and other information of the door can also be directly read by the equipment PLC.

High performance level brings high reliability

For automatic production line, interruption even one minute will cause immeasurable losses. Therefore, high safety performance level of related equipment components is required to ensure stable and reliable operation of the equipment.

• Pass EC type-examination by TÜV NORD in Germany, meets requirements of Annex 1 of the Machinery Directive 2006/42/EG, tested in accordance with EN ISO 13849-1:2015 and EN 62061:2005+A1:2013.
• Standard for integrated safety limit switch (PL e/ Cat.4) for accurately query door position.
• Standard for safety light grille (IP 67), Intelligent monitoring obstacles to protect closing zone and feedback to PLC in real time.

Quick and frequent opening/closing with high durability

The door can be open/close in high speed and high frequency, max. opening speed 1.5 m/s and max. closing speed 0.8 m/s, max. open/close cycle up to 250,000 within one year.

Full transparent curtain for better vision

Standard transparent curtain (without volatile silicon), bring more bright appearance and better vision, easy to observe the equipment at any time.

4 mm UPVC flat curtain with sturdy spring steel wind bar and aluminium bottom profile, also lead to better wind load resistance class 1 in accordance with Europe standard (wind class 9, wind pressure 264 – 366 Pa）.
