The main control device 300 stores and manages all access information transmitted from a plurality of revolving doors installed in the building.

In addition, the PSI 73 uses the signal detected by the first entry detection switch 32 to determine that the current rotating door operates in the entry direction, and the detection signal output from the second entry detection switch 44. It is determined that the current entry solenoid 42 is operating by, and as a result of the determination, if the entry solenoid 42 is normally operated when the revolving door operates in the entry direction, the alarm lamp 3 is lighted in green to turn the entry solenoid 42 on. If it is determined that the normal state of the operation, the rotating door is operated in the entry direction, but the detection signal is not output from the second entry detection switch 44, PLC 73 determines that the entry solenoid 42 is malfunctioning The alarm lamp (3) lights up in red so that the administrator can quickly maintain it.

Then, the first entry detecting switch 32 Position Cam (22)  When contacting the adjacent groove (22b) in the rotation direction of the entry drive unit 40 The entry solenoid 42  Operation is deactivated so that the entry stopper 41 1st rotor cam (23) At the latch stage 23a Jammed  This prevents people from returning out of the building.

In this case, the first extract detecting switch 33 is bent even when it is in contact with the protrusion 22a of the position cam 22 so as not to generate a signal.

In addition, the rotational force of the door 10 is converted to the linear reciprocating motion of the drive gear 25 through the idle gear 61-> pinion gear 62-> lex gear 63 is bitten by the gear 25a. As the gear gear rod 65 is drawn out from the hydraulic cylinder 64, the gear gear 63 moves toward the damper portion 69, and the damper rod 67 of the damper portion 69 passes through the support 68. Damper spring 66 is compressed when moving to prevent the door 10 is free to rotate.

And, when the entrance and exit is completed, the idle gear 61 is located in the space 25b of the drive gear 25 while the idle gear 61 and the pinion gear 62 are applied to the elastic force of the compressed damping puff 66. The rack gear rod 65 connected to the rack gear 63 is inserted into the hydraulic cylinder 64, and the damper rod 67 moves along the support 68 to return to the initial position.

At this time, when the return of the damper rod 67 is completed, the idle gear 61 is stopped at the position where the gear 25 is bitten by the gear 25a of the drive gear 25.

2. The operation for exiting the building, when the person recognizes the recognition card in the card reader (not shown) information is read through the automatic calling unit (ACU) and transmits a signal to the PLC (73).

In this case, the control unit 70 does not operate when the recognition card is not allowed access, and the PLC 73 of the control unit 70 operates when the recognition card is allowed access. A current is supplied to the exsolenoid 52 of 50).

Here, when the initial current is greatly supplied to the extract solenoid 52 and the extract stopper 51 is pushed, the extract stopper 51 is rotated with respect to the pivot shaft 202 and thus the second rotor cam 24 may be rotated. When the latch is released from the latch stage 24a, after supplying a weak current for a predetermined time for access, the entry stopper 41 is caught by the latch stage 23a of the first rotor cam 23 to prevent entry. Block it.

In addition, when the stopper 51 is deactivated, the contact stop switch 44 is contacted to transmit the deactivation signal to the PLC 73 of the control unit 70 so that the relay expansion board 74 may be used. When the non-operation code is displayed and the stopper 51 is operated, the contact of the extract detecting switch 44 is released, so that no signal is generated.

Afterwards, the first and second rotor cams 23 (the first and second rotor cams 23) are rotated while the driver pushes the access blocking bar 11 of the door 10 toward the outside of the building while the driving shaft 21 connected to the rotation shaft 12 of the door 10 rotates. 24, the position cam 22, the drive gear 25 is rotated at the same time.

Here, the first rotor cam 23 is rotated in a direction not to be caught by the entry stopper 41 of the entry driver 40 during rotation.

That is, while the bearing 24b installed on the lower surface of the second rotor cam 24 moves in contact with both sides of the sliding holes 81 of the position portion 80 along the vertex, the rod 83 of the guide 84 When the compression spring 82 is inserted into the compression spring 82 and passes through the top of the sliding hole 81, the compression spring 82 is pushed by the elastic force of the compression spring 82 to contact the two neighboring bearings 24b to open the door 10. Secure it in a location where access is not possible.

In addition, when the position cam 22 is rotated, the protrusion 22a is in contact with the position detecting switch 31 and the first extract switch 33, and the position detecting switch 31 is connected to the neighboring protrusion 22a. When the contact is completed, the entry and exit is completed is transmitted to the PLC 73 of the control unit 70 and the first EXIT switch 33 reads the direction of rotation and transmitted to the PLC 73 relay expansion board 74 ) And the operation signal is transmitted in the form of code.

Then, when the first extract switch 33 is in contact with the neighboring groove 22b in the rotational direction of the position cam 22, the extract solenoid 52 of the extract driving section 50 releases the operation. The stopper 51 is engaged with the latch end 24a of the second rotor cam 24 so that the person cannot enter the building.

Here, the first entry detection switch 32 is bent even when it is in contact with the projection 22a of the position cam 22 so as not to generate a signal.

In addition, the rotational force of the door 10 is converted to the linear reciprocating motion of the drive gear 25 through the idle gear 61-> pinion gear 62-> lex gear 63 is bitten by the gear 25a. When the rack gear rod 65 is inserted into the hydraulic cylinder 64, the damper spring 66 moves toward the rack gear 63 while the damper rod 67 of the damper portion 69 moves through the support 68. While being retracted, the rack gear rod 65 is supported by the hydraulic force when inserted into the hydraulic cylinder 64 to prevent the door 10 from freely rotating.

And, when the entrance and exit is completed, the idle gear 61 is located in the space 25b of the drive gear 25 while the idle gear 61 and the pinion gear 62 are applied to the elastic force of the compressed damping puff 66. The rack gear rod 65 connected to the rack gear 63 is drawn out of the hydraulic cylinder 64, and the damper rod 67 moves along the support 68 to return to the initial position.

At this time, when the return of the damper rod 67 is completed, the idle gear 61 is stopped at the position where the gear 25 is bitten by the gear 25a of the drive gear 25.

As a result, the entry solenoid 42 and the exsolenoid 42 of the entry driver 40 and the extract driver 50 have an advantage of extending the service life by controlling the strength of the required current.

In addition, the rotation speed control unit 60 during the rotation of the door 10 to suppress the free rotation of the door 10 has the advantage that can be prevented in advance safety accidents such as separation, pinching due to excessive rotation.

In addition, the PLC 73 checks the rotational position, rotation direction, operation / non-operation, and displays the code, and at the same time, the alarm lamp 3 checks whether the entry solenoid 42 and the exsolenoid 52 are normally operated. By displaying through, it is possible to easily determine the abnormality, determine the faulty parts, etc. There is a convenient management advantage.
