Of course, if the installation case 100 itself is a magnetic material such as metal, such a separate magnet seating portion 120 will be unnecessary.

Meanwhile, when the interlocking rotation operation state of the gas spring 300 according to the opening / closing operation of the opening / closing door 200 is described in more detail with reference to FIGS. 4 and 5, the opening / closing door 200 is opened as shown in FIG. 4. When the gas spring 300 rotates in association with the opening / closing door 200 about the first hinge shaft C1, the gas spring 300 is inclined by β angle in the outward direction of the installation case 100. In the gas pressure of the gas cylinder 310 acts in the direction of the arrow to keep the door 200 is kept open. Of course, if the open and close door 200 is rotated more than a certain period in the closed state, that is, if the gas spring 300 is rotated more than the open position in the vertical state, the gas spring 300 is installed in more than that section Since it is inclined in the outward direction of the 100, the gas pressure by the gas spring 300 acts as a pressure to open the opening and closing door 200, and thus the opening and closing door 200 is automatically opened without the operator's opening operation. do.

On the contrary, when the opening / closing door 200 is closed and rotated as shown in FIG. 5 in the open state, the gas spring 300 is interlocked with the opening / closing door 200 about the first hinge shaft C1. And it is positioned in the inclined state by the α angle in the inward direction of the installation case 100, in this arrangement state the gas pressure of the gas cylinder 310 acts in the direction of the arrow to keep the door 200 closed Keep it. Of course, even in this case, when the opening and closing door 200 is closed and rotated for a predetermined period or more in a fully open state, that is, when the gas spring 300 is closed and rotated for more than a section in which the gas spring 300 is positioned in a vertical state, the gas spring 300 is located in or more of the sections. ) Is inclined in the inward direction of the installation case 100, the gas pressure by the gas spring 300 acts as a pressure for closing the opening and closing door 200, thus opening and closing even if there is no closing operation of the operator in more sections The door 200 is not only automatically closed but also keeps the closed lock state by the gas pressure.

6 is an operating state diagram schematically showing a combined position change state of the safety door device for an automatic manufacturing facility according to an embodiment of the present invention.
