That is, when thin plate 2 is subject to external force R and is prevented from decline, by reversion cylinder 11b's during beginning turning
The sheet reeling 5 that retract action proceeds to invert by reversion pulley 8b, due to extracting out thin plate 2 in the sheet cassette 4
Winding is made to relax.And, reversion cylinder 11b proceeds retracting motion, is made by forward pulley 8a and rotating forward belt 31
The piston rod 34 of forward cylinder 11a carries out stretching out motion.For this purpose, the air pressure in forward cylinder 11a changes, into
It is the pressure lower than air pressure during normal closing operation.Then, the change quilt of the air pressure in this forward cylinder 11a
Reversion breakdown action control loop 9c is detected, and shuts off the air supply of reversion cylinder 11b sides and towards forward cylinder
11a sides carry out air supply.
Thus, the motion of stretching out of piston rod 34 is stopped by forward cylinder 11a, and directly making which carry out retracting motion makes thin plate
Reel 5 is rotated forward.And, the lax thin plate 2 of winding is produced in winder in above-mentioned sheet cassette 4, due to the thin plate for being rotated forward
5 one side of reel is tightly wrapped while proceeding by the rising of thin plate 2 winding lax（Reversion breakdown action）, therefore, from abut thing from
Open and stop in full-gear H.Then, after the factor of external force R by body etc. is removed, by reversion with cylinder 11b's
Normal retracting motion action, makes thin plate 2 swimmingly extract out and swimmingly carry out normal closing operation again.
And, as described above, in the abnormal closing motion of the thin plate 2 with external force R（Decline）The reversion of Shi Jinhang is opened
Action control, using forward cylinder 11a normal closing operation when and external force R cause abnormal closing motion when air pressure
The change of power carrying out, therefore, only switch over the letter of the valve of pressure detecting switching etc. by clamping in air loop
Clean and cheap structure just reliably can be controlled.And, reversion cylinder 11b and forward cylinder 11a, due to each other
By reversion pulley 8b and inversion belt 32 and forward pulley 8a and rotate forward belt 31 and associate with sheet reeling 5, therefore, it is right
There is resiliency with the impact when load variations drastically of external force R generation, reversion breakdown action, will not be in sheet reeling 5
Positive and negative rotation and thin plate 2 on-off action in there is inadequate situation.
That is, by resiliency during the flexible and winding and extraction of inversion belt 32 and rotating forward belt 31, make under thin plate 2
Impact when load variations occurred with the generation of external force R in drop action and reversion breakdown action etc. relaxes.Thus, energy
The damage of thin plate 2 and the deformation of piston rod 34 etc. are prevented, furthermore, it is possible to seek the protection of air control equipment etc..And, have
The thin plate rolling screen door 1 of the air actuated type of opening and closing device configured as described 7, as air is alternately supplied to forward
Cylinder 11a and reversion cylinder 11b make 5 positive and negative rotation of sheet reeling, so, especially fill with conventional air driven rolling screen door
Putting and comparing, it is not in that closing motion is slow that the thin plate 2 when Primary closure action can be made by reversion cylinder 11b declines
It is slow, promptly carry out.And, by adjusting to the air supply in each cylinder part 33, can freely set the opening and closing of thin plate 2
Speed, goes for multiduty air type roller door arrangement.
The thin plate rolling screen door 1 of the opening and closing device 7 for constituting as described above is provided with, in the blocking of the thin plate 2 shown in Fig. 1
Under, by by test section 9b to carrying out detection by body detecting opening operation, by or Operation switch 9a opening operation
Operation is started, and air is supplied to forward cylinder 11a by air tank 56 and control panel 9 from air supply unit 10.By
This, the piston rod 34 of forward cylinder 11a carries out retracting motion by high air pressure, and drawing rotates forward belt 31 and taken out
Go out while rotate forward forward pulley 8a and sheet reeling 5, the opposing deadweight winding of thin plate 2 is increased.
Now, the inversion belt 32 for being wound by the reversion pulley 34 for being rotated forward, makes the work of reversion cylinder 11b
Stopper rod 34 to be resisted and discharge the air in cylinder upper from dynamic resistance while carrying out stretching out motion.And, pulley 8b is used in reversion
Inversion belt 32 in tensioning state can be rolled tightly while being wound from dynamic resistance by above-mentioned.And, rotate forward
Cylinder 11a is used, in the lower position of the piston rod 34 for carrying out stretching out motion, makes thin plate 2 become full-gear, hold mode
While becoming the standby attitude of decline.
Then, when test section 9b is not present by body because being detected by by body, or by Operation switch 9a
Closing motion is operated, and air is supplied to reversion cylinder 11b by air tank 56 and control panel 9 from air supply unit 10.By
This, reversion carries out retracting motion by low air pressure with the piston rod 34 of cylinder 11b, and drawing inversion belt 32 extracts one out
While being inverted reversion pulley 8b and sheet reeling 5, extract out thin plate 2 and decline.
When this thin plate 2 declines, the rotating forward belt 31 on forward pulley 8a, by opposing with thin plate 2
The down-force that deadweight is produced carry out stretching out the piston rod 34 of motion from dynamic resistance, be not in loosely to roll up in a tensioned state
It is wound on forward pulley 8a, then, the breakdown action of the thin plate 2 for carrying out is carried out rapidly.And, cylinder 11b is used in reversion,
The lower position of the piston rod 34 of retracting motion is carried out, has made that thin plate 2 becomes full-shut position and hold mode is while become
