Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement in a half-open position setting device for an automatic door.

(Conventional technology and its problems) Conventional automatic doors fully open and close the door by turning on and off switches placed in front and behind the door, but the door cannot be fully opened even when only one person is passing by. However, fully closing it consumes a lot of energy and is uneconomical.

In order to solve the above-mentioned problem,
As described in Publication No. 21681, an automatic door that measures the number of people coming and going in a certain period of time in the past and compares it with a predetermined standard value, and if the result is less than the predetermined standard value, the opening amount of the door is set variably. It has been known.

However, according to this conventional technology, the variable opening amount (half-opening amount) of the door is selected from among those preset by the manufacturer, such as 50% open/close, 70% open/close, etc., so the location, season, time of day, etc. In other words, it is almost impossible to obtain the optimum half-opening degree for each automatic door depending on the amount of traffic that varies widely.

(Object of the Invention) The present invention has been made in order to eliminate such conventional problems, and its purpose is to provide an automatic door in which the half-opening degree can be arbitrarily set and the setting method is extremely easy. An object of the present invention is to provide a half-open position setting device.

(Structure of the Invention) The automatic door half-open position setting device of the present invention includes a counting section that detects the half-open setting position of the door based on the opening/closing movement amount of the door and the corresponding motor rotation speed, and a counter section that detects the half-open setting position of the door by the counting section. a memory unit that memorizes the position;
and a motor control unit that opens and closes the door to the half-open set position stored in the storage unit, and the counting unit and the storage unit are connected to each other via a main power switch.
The control section is connected to a power source via a main power switch and a sub power switch, respectively, and the counting section and storage section are manually moved to an arbitrary half-open position with both the main and sub power switches turned off. The initial half-open setting position of the door is detected by the counting section by the closing movement of the door after the main power switch is turned on, and is stored in the storage section, and the motor control section is configured to turn on both the main and sub power switches. In this state, the door is opened and closed to the initial half-open setting position.

(Example) An embodiment of the present invention will be described with reference to the drawings.

Reference numerals 13 and 13 in FIG.
A horizontal frame 14 is provided above the 3 and 13 to form a gate shape.

A rail 15 is provided horizontally on the lower edge of the horizontal frame 14, and the door 1 is provided on this rail 15 so as to be movable in the horizontal direction.

The door 1 has a glass plate 1 between the upper stile 1a and the lower stile 1b.
The upper stile 1a has a door wheel 1.
6, 16, 16, 16 are provided rotatably in line in the horizontal direction, and this door wheel 16, 16, 16, 16
can move freely on the rail 15.

A guide pulley 8b is provided on one end side of the horizontal frame 14,
A drive pulley 8a is provided at the other end, and
A belt 8 is stretched between both pulleys 8a and 8b, and the belt 8 and the door 1 are linked by a metal fitting 17, so that the door 1 is opened and closed by the rotational movement of the belt 8.

The drive pulley 8a is linked to a motor 7 via a speed reducer 8c, and is configured to drive the drive pulley 8a and open/close the door 1 by rotating the motor 7 in the forward and reverse directions.

A close limit switch 10 for detecting that the door 1 is closed is provided in the door closed position of the horizontal frame 14, and an open limit switch 11 for detecting that the door 1 is fully opened is provided in the fully open position of the horizontal frame 14.

In the figure, A is a controller, 5 is a main power switch, and 6 is a sub power switch.The main power switch 5 is installed in the horizontal frame 14 because it is used less frequently, and the auxiliary power switch 6 is installed in the horizontal frame 14 because it is used more frequently. It is provided on the wall surface 20 outside the automatic door.

In addition, the Matsuto switch 9 is placed in the fully closed position of the door 1.
is provided and serves as a starting switch for opening the door 1.

Next, the control device of this embodiment will be explained with reference to FIG. 2. The controller A includes a motor control section 4, a pulse storage section 3, and a pulse counting section 2.

The motor control unit 4 controls the rotational direction, number of rotations, and rotational speed of the motor 7, and controls the opening and closing movement of the door 1 via a transmission mechanism such as a belt 8.
A power source is connected to this motor control section 4 via a main power switch 5 and a sub power switch 6.

The motor 7 is provided with a pulse generator that generates a current with a number of pulses proportional to the number of rotations of the motor 7, and this pulse generator is connected to the pulse count section 2.
It is connected to the.

The pulse counting section 2 detects the number of rotations of the motor, that is, the amount of opening/closing movement of the door by counting the number of pulses of the pulse generator. When the door is subsequently closed, the number of pulses corresponding to the initial half-open setting position of the door, that is, an arbitrary half-open setting position (hereinafter referred to as the setting position) is input into the pulse storage section 3. When the motor 7 is being driven after the door is set to the half-open position, the pulse counting section 2 sequentially inputs the number of pulses corresponding to the rotation speed to the motor control section 4.

The pulse storage section 3 is connected to the main power switch 5, the pulse counting section 2, and the motor control section 4, and stores the number of pulses input from the pulse counting section 2 first after the main power switch 5 is turned on. This number of pulses corresponds to the set position of the door. Then, while the motor 7 is driving, the number of pulses corresponding to the set position of the door is input to the motor control section 4.

The main power switch 5 is a power switch for the pulse storage section 3, pulse counting section 2, and pulse generator, and by turning on this switch 5, the set position of the motor 7 can be detected and stored.

The auxiliary power switch 6 is a power switch for the motor control section 4, and when the switch 6 is turned on, the automatic door is activated, but whether the switch 6 is turned on or off has no relation to the detection and storage of the set position.

Further, a mat switch 9, a close limit switch 10, and an open limit switch 11 are connected to the motor control section 4, respectively.

If the set position is too narrow, the opening will only open by about 10 cm, making it unusable for traffic, so the number of pulses corresponding to an opening of 40 cm, for example, is preset in the pulse storage section 3, and all settings below 40 cm will open. Cancel and set the setting position to 40cm or more.

Next, the operation of this embodiment will be explained.

First, turn on the main power switch 5 and the sub power switch 6.
Turn off the door 1, move the door 1 to any half-open position, for example, turn the Matsuto switch 9 as shown in the imaginary line in Figure 1.
Align it with the edge 9a.

When the main power switch 5 is turned on, the pulse storage section 3, pulse count section 2, and pulse generator are started, and the initial half-open position of the motor 7 corresponding to the set position of the door 1 is set by the subsequent door closing operation. , the number of pulses is detected by the pulse generator and pulse counting unit 2, and the pulse storage unit 3 stores this number of pulses. That is, when the main power switch 5 is turned on and then the sub power switch 6 is turned on, the motor control section 4 is activated and the motor 7 is activated to close the door 1, but the door 1 does not activate the close limit switch 10. When it is turned on, it detects that the motor has closed, and the motor 7 stops. During that time, the number of revolutions of the motor 7 is detected as a pulse number by the pulse generator and pulse counting section 2, and this number of pulses is set as the set position and the pulse is set. The storage unit 3 stores it.

When a passerby passes by and the matsu switch 9 is turned on, the motor control section 4 drives the motor 7 to open the door 1, and at the same time the pulse count section 2 detects the pulses from the pulse generator. The motor control unit 4 compares the number of pulses stored in the pulse storage unit 3 and the number of pulses with the pulse count unit 2, and when they match, that is, at the initial rotational position of the motor 7 corresponding to the set position of the door 1, the motor is started. Stop 7. Then,
The door 1 stops at an initial half-open setting position, that is, an arbitrary half-open setting position.

After the opening hold time has elapsed, the motor control unit 4 switches the motor 7
is driven to close the door 1, and when the closing limit switch 10 is turned on, the motor 7 is stopped and the door 1 is on standby.

If a passer-by turns on the mat switch during the open hold time or during the closing operation, the door 1 will open again, the open hold time will be reset, and the closing operation will be repeated.

When the day's work is finished, turn on the sub power switch 6.
Turn off. Door 1 becomes free and can be opened and closed manually. The next day, it is only necessary to turn on the sub power switch 6, and the set position is stored in the pulse storage section 3.

If it is desired to change the setting position, turn off the main power switch 5 and repeat the above-described detection and storage operations.

(Operations and Effects) Since the present invention is configured as described above, the initial half-open setting position of the door manually moved to an arbitrary half-open position is detected and stored, and the door is opened/closed to the arbitrary half-open setting position. can be done.

Therefore, the opening amount (half-opening amount) of the door is 50% open/closed, 70%
Compared to conventional products, which are limited to % opening/closing settings set by the manufacturer in advance, it is extremely easy to set the optimal half-opening degree for each automatic door according to the traffic volume, which varies greatly depending on the time of day, location, season, etc. You can get it at

In addition, since current is always supplied to the memory unit via the main power switch, the half-open position once set can be memorized as long as the main power is turned off, and once the main power is turned off, the set position can be easily changed. This method has many advantages, such as eliminating the need for a dedicated battery pack for the storage section.
