Description

[Detailed Description of the Invention] This invention relates to a starting switch device for an automatic opening/closing door using a touch switch.

Generally, a device for automatically opening and closing a door using a touch switch (mechanical switch, capacitive switch, etc.) attached to the door has a configuration as shown in FIG. That is, a touch switch 8 is mounted on the handle at the side end of the door 1 at the height of a passerby's hand.
At the same time, the door 1 is suspended via sliding rollers 3, 3 on a channel (base) 2 fixed to the building side, and sprocket wheels 4, 5 are mounted on both ends of the channel 2 as shafts. Chain 6
Stretch it. Then, the door 1 is opened and closed by engaging the lower part of the chain 6 with the door 1 and rotating the sprocket wheel 4 from the motor control circuit 7 via the motor and the speed reduction mechanism. ing. However, touch switch 8
The touch signal from the door 1 is applied to the extendable helical cord b in the blind 2 through the wiring a in the door 1, thereby starting the motor control circuit 7 to open and close the door 1. However, in such a conventional start switch device, as described above, the wiring a,
It uses a helical cord b and a slip contact to connect it, and has the disadvantage that failures occur frequently because the door 1 is opened and closed frequently.

Therefore, the purpose of this invention is to eliminate such drawbacks, and by making a connection without a cord, the structure is simplified and the number of failures is drastically reduced.

This idea will be explained below.

This invention relates to a start switch device for an automatic opening/closing door, as shown in Figure 2, corresponding to Figure 1.
A touch switch 8 is disposed on the handle of the door 1 to be opened and closed, and a touch switch 8 is provided in the blind 2 at the top of the door 1 which oscillates in response to the touch signal TS from the touch switch 8 and emits the oscillation output. An oscillation device 10, a light reception control device 20 provided on the building side in the mume 2 for receiving the light emission output PS from the oscillation device 10 and controlling the opening and closing of the door 1 via the motor control circuit 7. is provided, and signals are transmitted and received between the door 1 and the building side (door drive side) using an optical PS. Therefore, the touch switch 8, the oscillation device 10, and the light reception control device 20
For example, the touch switch 8 has a configuration as shown in FIG. It is configured with a power source (for example, a dry battery) 83. The oscillation device 10 also includes IC inverters _Q1 and _Q2 , a capacitor _C1 and a resistor _R3 , and a resistor _R1 , a diode _CR2 , and a resistor _R2 connected in parallel between the input and output of the inverter _Q2 . In addition to configuring a pulse oscillator, the oscillation output of inverter Q ₂ is input to the base of transistor Q ₃ via resistor R ₄ , and a light emitting diode CR ₁ is connected to the emitter of transistor _Q 3 as a light emitting element. ing. The light reception control device 20 has a photodiode CR ₃ as a light receiving element that receives the optical signal PS from the oscillation device 10, and its photoelectric conversion output is provided by a capacitor C ₂ , an amplifier Q ₄ , a capacitor C ₃ ,
Amplifier Q ₅ , capacitor C ₄ via diode CR ₄
The binary output CM is smoothed by CM and input to the comparator _Q6 , and compared with the reference voltage _VS.
is now input to the base of transistor _Q7 , which has relay RY connected to its collector.
Note that the oscillating device 10 is fixed to the upper part of the door 1, the receiving control device 20 is fixed inside the door 2, and the light from the light emitting diode CR ₁ of the oscillating device 10 is
PS is a photodiode in the light receiving control device 20
It is now possible to receive light at CR ₃ . Therefore, the oscillating device 10 moves within the door 2 as the door 1 opens and closes.

In such a configuration, during normal operation, that is, when the door 1 is closed, the switch 82 of the touch switch 8 is off, and the power 83 is not supplied to the oscillation device 10, so that the light emitting diode CR ₁ It's not even emitting light. Therefore, the photodiode _CR3 of the light reception control device 20 does not receive the light PS, and the output of the comparator _Q6 is also "L", and the transistor _Q7 is turned off, and the relay
RY is blocked. However, when a passerby touches the touch plate 81 of the touch switch 8, the switch 8
2 is turned on, and the voltage of the power supply 83 becomes the touch signal.
It is transmitted to the oscillation device 10 as a TS. As a result, voltage is applied to the collectors of inverters Q ₁ and Q ₂ and transistor Q ₃ , and the oscillator oscillates pulses with a repetition width of a time constant of C ₁ and R ₂ . Therefore,
Correspondingly, transistor Q ₃ repeatedly turns on and off, and emitter-connected light emitting diode CR ₁
emits light. In this way light emitting diode CR ₁
The light PS emitted from the is received by the photodiode CR ₃ , and the photoelectric signal is amplified by the amplifiers Q ₄ and Q ₅ , so its value becomes larger than the reference voltage _VS , and the output of the comparator Q ₆ becomes “ H”. In this way, the transistor _Q7 is turned on and the relay RY connected to the collector is made conductive, so that the contact signal WS is output from the relay RY and the door 1 can be opened via the motor control circuit 7.

By the way, when using a low current IC such as CMOS, as shown in _FIG . , it is also possible to start oscillation by this.
In addition, in the case of a draw type automatic door, as shown in Fig. 5, there is a touch switch 8 on the doors 1A and 1B.
A, 8B are installed, and corresponding oscillation devices 10A, 10B are provided on the doors 1A, 1B,
The light reception control device 201 arranged in the middle part
All you need to do is to receive PSA and PSB. In addition,
In this case, the light reception control device 201 is equipped with two light receiving elements, and one of the light receiving elements controls the optical PSA,
Doors 1A and 1B are opened when PSB is received. However, with one photodetector, light
In order to receive PSA and PSB, mirrors 201A and 201B may be used as shown in FIG. That is, the light from the oscillator 10A
The PSA is reflected by the mirror 201A and the light receiving element 20
The light PSB from the oscillator 10B is reflected by the mirror 201B and is irradiated onto the light receiving element 202.

As described above, this invention has the advantage that there is no wiring to connect the door 1 and the door 2, which is advantageous in terms of structure and reduces failures. In addition, since the light is transmitted inside the eye, there is little influence from outside light, and it can be configured with a relatively simple circuit.
It has the advantage of being less susceptible to electrical noise.

In addition, although the above description shows a light emitting diode as a light emitting element and a photodiode as a light receiving element, it goes without saying that other elements can also be used.
