Description

[Detailed description of the invention] This invention relates to a Matsuto switch for automatic doors.

Conventionally, a door opening signal is issued when a passerby steps on a Matsuto switch installed on both sides of the door, and this signal automatically opens the door.Sliding and swing-type automatic doors. is widely used.

Incidentally, in buildings equipped with automatic doors, the interior of the building is often air-conditioned, such as heating and cooling. In such buildings, if the automatic doors are opened and closed frequently, there is a problem that cold or warm air inside the building will be dissipated to the outside through the automatic doors, reducing air conditioning effectiveness and increasing electricity costs for air conditioning. be.

Therefore, in order to minimize the drop in air conditioning effectiveness as described above, the movement speed of the automatic door should be increased, or the automatic door control device should be equipped with a microcomputer to control the number of times the door is opened and closed. Methods such as reducing the opening width of the door (leaving it half-open) are being considered. However, with doors that move at a faster speed, infants, elderly people, etc. with slow body movements may get caught in the door, and those equipped with a microcomputer are expensive and depend on the number of times the door is opened and closed. Since the opening width is small, there are drawbacks such as large objects (width) that cannot pass through the door.

This idea was developed in view of the above circumstances, and is a Matsu switch for automatic doors that can control the opening width of the automatic door depending on the size and direction of the object passing through, thereby minimizing the reduction in the air conditioning effect. The Matsuto switch is divided into two or more sections along the flow line of passing objects, and is configured to generate an opening signal for each section, and automatically opens the door based on the opening signal. The feature is that the width can be controlled.

This invention will be explained in detail below with reference to the drawings.

Contact SB turns ON.

Next, the operation of opening/closing an automatic door using the matsu switch configured as described above will be explained with reference to FIGS. 3 to 5.

First, the mat switch 11 is installed on the floor of the automatic door body 12 on the door entrance side and the exit side, respectively, as shown in FIGS. 3 and 4. At this time, the matsu switches 11, 11 move the upper electrode plates 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 4, 3, 3, 4 in a direction perpendicular to the opening/closing direction of the doors 13, 13, that is, in the direction of the flow line of passersby with respect to the doors 13, 13, as shown in FIG. The upper electrode plate is arranged so that the longitudinal directions of the upper electrode plates 4 and 5 coincide with each other, or in other words, the upper electrode plate is divided into three parts along the flow line of passing objects.

FIG. 3 shows the sliding automatic door body 12, and the opening frame 14 is formed by an upper blind 15 and vertical frames 16, 16 on the left and right sides.
A door hanging rail 17 is attached along the rail 17, and door wheels 19, 19, 19, 19 attached to the door hanging fittings 18, 18 of the doors 13, 13 run on the rail 17. Also,
A guide pulley 21 around which a belt 20 is wound and a drive pulley 22 are attached near both ends of the rail 17, and the drive pulley 22 is driven by a motor 23 with a speed reducer. One of the door hanging fittings 18 is connected to the lower side of this belt 20, and the other door hanging fitting 18 is connected to the upper side, so that when the belt 20 is fed and driven, the door hanging
3 and 13 move in opposite directions to open or close. In addition, a fully open position detection switch 24 is located near the drive pulley 22 of the blind 15.
is installed, and this fully open position detection switch 24
A half-open position detection switch 25 is installed at a position closer to the guide pulley 21 by a distance corresponding to about half the width of the door 13 from the half-open position detection switch 25. A closed position detection switch 26 is installed at a position closer to the guide pulley 21 by a distance of
A position detection switch operator 27 attached to the upper part of the hanging metal fitting 18 of the door 13 on the second side can be turned on and off as the door 13 moves. Furthermore, at the bottom of the doors 13, 13 there are anti-flare pieces 28,
28... are fixedly installed, and these anti-flare pieces 28, 28
... is a door flailing prevention rail 30 provided on the floor 29
It is loosely fitted inside.

FIG. 5 shows an example of a control circuit for controlling the opening and closing of the automatic door body 12 described above.
3 indicates a state where the device is stopped at the closed position as shown in FIG. That is, the closed position detection switch 26 is turned on, the closed position stop relay X3 is operated, and the motor circuit for rotating the doors 13, 13 in the closing direction is turned off. Next, when a passerby steps on the upper central electrode plate 3 of the matsuto switch 11, the central contact SA turns ON, the motor forward/reverse switching relay X1 operates, and the motor 23 moves in the direction of opening the doors 13, 13. Rotate, door 13,1
3 begins to open. Half-open position detection switch 25
When the doors 13, 13 open to the ON position, the open position stop relay X4 operates, and the motor circuit that rotates the doors 13, 13 in the opening direction turns OFF.
The doors 13, 13 stop at a halfway open position (hereinafter referred to as a half-open position) before fully opening. Then, when a passerby passes through the doors 13, 13 and leaves the Matsu switch 11 on the opposite side, the motor forward/reverse switching relay X1 returns, and the motor 23
3, and the doors 13, 13 begin to close. When the closed position detection switch 26 is turned ON, the closed position stop relay X3 is operated, and the doors 13, 13 are stopped at the closed position shown in FIG.

In addition, when two or three passersby pass at once, when a large passing object such as a car passes, or when passersby approaches the doors 13, 13 diagonally, , Matsuto Switch 1
The side contact SB of No. 1 or the side contact SB and the center contact SA are turned ON. Then, the motor forward/reverse switching relay X1 and the half-open switching relay X2 operate, the motor 23 rotates in the opening direction, and the doors 13, 13 begin to open. Before the doors 13, 13 are fully opened, the position detection switch operator 27 turns on the half-open position detection switch 25, but since the contact of the half-open changeover relay X2 is open, the open position stop relay X4 does not operate. Doors 13, 13 continue to open. Then, when the doors 13, 13 reach the fully open position, the fully open position detection switch 24 is turned on, the open position stop relay X4 is activated, and the motor 23 is stopped. When a passing object passes and leaves the Matsuto switch 11, the motor forward/reverse switching relay X1 and the half-open switching relay
3 and 13 are closed.

In this way, the matsuto switch 11 is divided into three sections along the line of flow of passersby, etc., and the opening signals for the doors 13, 13 are generated separately from the center and both sides, and these signals In response to the,
Since the opening degree of the doors 13, 13 is set to be fully open or half open, when there is only one person passing by or when the width of the passing object is narrow, the doors 13, 13 are opened by an opening signal from the center of the Matsuto switch 11. When there are two or three passers-by, the width of the passing object is large, or the passerby's direction of travel is diagonal, the doors 13, 13 will be fully opened by the open signal from both sides, and eventually the door will be closed. Depending on the size, width, and direction of movement of the object, the doors 13, 13 are half open or fully open. Therefore, unnecessary opening of the doors 13, 13 is eliminated, less cold air or warm air escapes from the doors 13, 13, and deterioration of the air conditioning effect is minimized.

Note that the structure of the matsuto switch 11 is not limited to that shown in FIGS. 1 and 2; for example, it may be made of pressurized conductive rubber (usually pressurized in an insulated state) in which metal particles are dispersed in silicone rubber using a special method. ), etc., and may be similarly divided into two or more sections along the line of flow of passing objects; in short, it is divided into two or more sections along the line of flow of passing objects, Any switch element that generates an open signal for each section may be used. Further, the automatic door main body 12 is not limited to the double-opening type shown in FIG. 3, but may be a single-opening type.

6 and 7 show an example in which the pine switch 11 of this invention is applied to a swing type automatic door, and the same components as those shown in FIGS. 3 to 5 are given the same reference numerals. The explanation will be omitted. The reference numeral 31 in the figure is a swing type automatic door body, and this body 31 consists of vertical frames 16, 16 and a blind 15.
an opening frame 14 consisting of an opening frame 14, swing door drive units 32, 32 attached to the blind 15, doors 13, 13 that are driven to open and close by these swing door drive units 32, 32; 13 and the drive shaft 33 connecting the drive parts 32, 32,
33, and support shafts 34, 3 that support the doors 13, 13.
It consists of 4. Further, the mat switches 11, 11 of this invention are arranged along the flow line of passing objects, similar to the examples shown in FIGS. 3 and 4. And the center contact of Matsuto switch 11
By connecting SA and side contact SB to the control circuit shown in Figure 5, center contact SA can
It turns on, and the doors 13, 13 open approximately 60 degrees from the closed position and then stop (half-open position). 2-3 more
When a passerby or a large passable object passes, or when a passerby approaches the doors 13, 13 diagonally, the side contact SB or the side contact SB and the center contact SA are turned ON. Then, the doors 13, 13 open 90 degrees from the closed position (fully open position) and stop.

Therefore, in this example as well, depending on the size, number, width, and direction of movement of passing objects, the door 13,1
3 is considered half open or fully open.

As explained above, the automatic door matsuto switch of this invention is configured so that the matsuto switch is divided into two or more sections along the flow line of passing objects, and a door open signal is generated for each of these sections. Since the opening width of the automatic door can be controlled based on the opening signal, two or more types of door opening signals can be generated depending on the number, width, direction of movement, etc. of passing objects. Therefore, the opening degree of the door can be controlled according to the condition of the passing object by this opening signal, and as a result, unnecessary opening of the door is eliminated, and cold air and warm air are less likely to escape from the door. This minimizes the decline in air conditioning effectiveness. Furthermore, the power cost for opening and closing the door can be reduced.
