Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for automatic doors, blinds, shunters, curtains, etc. (hereinafter referred to as automatic doors, etc.).

When controlling the opening and closing of doors, automatic l/Atsuka electric mechanisms generally detect left and right or 1. A large h limit switch and a passenger detection switch are placed at the lower f9f fixed position, and when they are turned ON/OFF, the deceleration of the motor, stop I, etc. are set to 1.

On the contrary, when actually arranging the detection switch (11), there is a problem in that it takes an hour to properly wire and also requires position adjustment of the detection switch. That is, in the conventional device, the electric mechanism is opened by detecting the position of J3n, etc., so this is a bit of an inconvenience.

The present invention has been made in view of the circumstances described in 1. The first point is that the Jlt'P award does not rely on M/, l detection, and therefore uses a detection switch such as a rimin l□ switch. Automatic door control J1 that solves the problem described in 1.
1 device.

Therefore, the control device ζ-1 of the present invention has a power supply circuit that supplies power to the city machine for driving driven objects such as 1-I moving doors, and a power supply circuit that is inserted into the power supply circuit 11. , outside::r+
a power supply control means for controlling the opening and closing of the power supply circuit by being energized by the electric power applied from the electric motor; 11 The means is configured to: -1- be temporarily monitored when the distribution motor starts] - close the distribution circuit, and thereafter maintain the monitored state by the power generated by the 11 generator. It is something.

Hereinafter, examples of the assembly of the present invention will be described with reference to accompanying drawings.

FIG. 1 is a circuit diagram showing a specific example of a control device according to the present invention. This device is driven by a power supply circuit 3 that includes a transformer 1 that transforms AC 100V, and a rectifier circuit 2 consisting of a diode bridge and a capacitor CI. be done. 4 is an AC motor + that drives a driven object (not shown) such as an automatic door.
The electric motor 4 is supplied with a market voltage of AC 100V through a power supply circuit 5. The power supply circuit 5 includes a two-winding launching relay (1) as a means for determining the rotational direction of the motor 4, and a relay (1) as a means for controlling power supply by opening and closing the power supply circuit 5. 2 is included in the contact point of 2. In addition, the two terminals of the AC motor 4 whose connection is switched by one contact to the relay (pHp)
A capacitor C2 is connected between the two.

1 is connected to the rectifier circuit 2 in the two-turn Madaraizumi launching relay, while push button switches RO A and 6B for opening and closing automatic doors, etc. are connected to each of the 3 wires. , when you press 6b, 1 contact is applied to the relay.
is activated, and the connection state between the supply circuit 5 and the upper movement vi4 is changed;
, therefore, the direction of rotation of the electric motor 4 is determined. Further, the push button switches 6a and 6b are connected to the 11" column circuit of the relay 2 and the field-close push button switch 8 through the tie-off I/7.

Furthermore 1. A power generation circuit 11 including a generator 9 and a rectifier circuit 10 consisting of a TAIO I/BRIFGE and a capacitor C3 is also connected to the relay 2 via TAIO 1 and 12. Generator 9 (O, -1) of this starting circuit
-1 By being connected to the shaft of the electric motor 4, it operates in conjunction with the shaft of the electric motor 4, so that when the lift engine 4 rotates, it generates electric power. \, In addition, the capacitance jv of each capacitor in the L-leg circuit is C1, C
3='200gF, C2=20gF.

Since the illustrated control ql'll device is constructed as described above, its operation is as follows.

First, in order to start the electric motor 4, when you press either of the push buttons 6a and 6b, 711U current flows from the power supply circuit 3 through relay 1 and relay 2, so the relay The contact kl of Kl is set at a position corresponding to each pushbutton switch 6a, 6b. For example, if the push button switch 6a is an opening switch, when the push button switch 6a is pressed, the contact kl is set to a position pl (FIG. 1) that rotates the electric motor 4 in the direction of opening. =-force, the contacts of 2 on the relay are set to the closed state from the illustrated closed state y-1. As a result, current flows to the motor 4 through the power supply circuit 5, and the motor 4 moves in a predetermined direction (
For example, in the direction in which Hi' is opened). At the same time, the generator 9 operates to generate a predetermined rectified voltage at the output end of the power generation circuit 11. This power generation continues as long as the electric motor 4 times It:L #i'a even after the pushbutton switch LO a or 6b is stopped being pressed, so the relay 2 continues to be energized.

In this way, when the moving door 151 operates in the opening direction or the closing direction, or when the driven object reaches the fully open position or the closed position +Ft and cannot move any further, the electric motor 4 prevents the rotation. be done. As a result, the generator 9 stops generating power, and the output from the power generation circuit 11 becomes zero, so that Sl/-=K2 is no longer excited, and the contact 2 is opened, that is, turned OFF. Become. Therefore, the gravity supplied to the electric motor 4 through the power supply circuit 5 is automatically cut off, and the electric motor 4 is stopped.

Furthermore, if the driven object cannot be moved due to an obstacle during opening or closing, the electric motor 4 will be overloaded in the same way as described above, and the rotation of the electric motor 4 will be blocked. The output becomes zero, and the power supply circuit 5 is cut off. In other words, this 11th point (2) device also has the function of a safety device.

In addition, in the specific example 1-, by pressing the normally closed push button switch 8 connected to the relay in line with 2,
By turning off the contacts of relay K2, it is possible to stop the driven object even in the middle of opening or closing.

Next, when the current flowing through the electric motor 4 in the control device δ is large, and therefore 2 is used as a power supply control means for a relay having a large contact capacity.

It is necessary to provide a generator with sufficient power to energize and maintain such a relay. However, since it is not economical to provide a generator with a large power generation capacity, it is desirable that even a generator with a small power generation capacity can drive the relay 2 for the personnel and equipment 2. Second
FIG. 3 shows a control device in such a case.

First, in the device shown in Fig. 2, 3 and 4 are connected to the third relay that can be directly monitored by the generator 9, which has a small power generation capacity, and this is connected to the power generation circuit 11 in place of the large capacity relay 2. On the other hand, 2 is connected to the relay in parallel with 1 to the in-line launching relay.

Therefore, when pushbutton switch 6a or 6b is pressed, relays 1 and 2 are set to 1, similar to the device shown in FIG.
7I7 is magnetized and the electric motor 4 and starter 9 are started. Therefore, the third relay is energized by the output of the starting circuit 11, and its contacts are closed. Therefore, even if the pushbutton switch LO a or 6b is turned OFF, the relay 2 continues to be energized and the contact 2 is kept closed.

When the motor 4 reaches the fully open or fully closed position or an obstacle prevents the rotation of the motor 4 and power generation stops, contact 3 opens in the third relay and energizes the relay 2. is cut off. Therefore, the contact 2 is opened, the power supply circuit 5 is cut off, and the power supply to the motor 4 is stopped, as in the case of FIG. 1.

On the other hand, the device shown in FIG.
2 is activated. That is, instead of the large capacity relay 2, the transistor T is connected to the generator circuit 11 through the resistor R1, while the relay 2 and the diodes Dl-D4 are connected to the knee-winding Munching relay Kl.
HN is connected in parallel with the transistor T, and a relay 2 is connected to the collector of the transistor T. Note that the values of the resistor R1 and the resistor R2 connected to the base of the transistor T are both 50Ω, and the capacitance of the capacitor C3 in the power generation circuit 11 is 50IJ.F.

Therefore, when the push button switch 6a or 6b is pressed, the relays 1 and 2 are energized and the motor 4 and generator 9 are started, similar to the above-described device. and,
The output of the power generation circuit 11 is amplified by the transistor T and applied to the relay 2. Therefore, the push button switch
Even if the switch 6a or 6b is turned off, the relay 2 continues to be energized and maintains the closed state 8 at its contact point.

When the rotation of the electric motor 4 is blocked by reaching the fully open or fully closed position or by an obstacle, and power generation is stopped 1-, the power to the large capacity relay 2 is cut off. Therefore, the contact point 2 opens, the power supply circuit 5 is cut off, and the power supply to the motor 4 is stopped, as in the case described above.

In the case of the example below, the power supply circuit 5 is directly opened and closed by the contact 2 of the relay, or the 41st
As shown in the figure, a triac TR may be interposed in the power supply circuit 5, and the triac TR may be connected to two contacts of the relay.

Furthermore, although the illustrated arrangement of 11 is an example in which an AC motor is used, even in a power supply circuit for a DC motor, by interposing 2 in the relay's contact point 2, it is possible to completely eliminate the The action and effect of tl) are shown.

Furthermore, in the specific example described in -1-, the supply control means and 1. Although a relay is used, other control means (for example, a semiconductor element) may be used.

As described above, according to the ilj control device of the present invention, a driven object such as automatic) A or the like reaches a predetermined state (for example, 1. f door is fully open or the fully open position). At that time, the electric motor was overloaded and the power supply control method using the generated power from the generator was released and the power supply to the electric motor was stopped. It is possible to control automatic doors etc. without detecting the position of the door.
It can also function as 1, where m is a safety device when a harmful substance is present.
