Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a double door automatic door device. In particular, the present invention relates to measures for improving workability when installing a double door automatic door device to a door opening.

[0002]

2. Description of the Related Art A double door type automatic door device for automatically opening and closing a door opening has been known.
In this type of automatic door device, for example, Japanese Patent Application Laid-Open No. 9-3030
As disclosed in Japanese Patent No. 42, the cost is reduced by making the two doors have substantially the same configuration. Guide rollers rotatable around a horizontal axis are attached to the upper ends of these two doors, respectively. On the other hand, a guide rail is provided in the door opening where the automatic door device is installed, and a guide roller of each door is locked to the guide rail, whereby each door is suspended in an eyeless manner. ing. Thereby, each door is slidably supported so as to open and close the door opening.

Further, a motor having a rotating shaft extending in a horizontal direction perpendicular to the sliding direction of the door is provided at one end of the blind horizontal direction. A pulley is attached to the rotating shaft. On the other hand, a pulley rotatable about a horizontal axis is also provided on the other end side in the horizontal direction. A belt is stretched between the pulleys, and each door is connected to the belt. Thereby, each door slides (slides in a direction approaching each other or in a direction away from each other) as the belt travels with the driving of the motor, and opens and closes the door openings. In addition, a controller for controlling driving of the motor is attached to the eye.

[0004]

As described above, in the conventional double door type automatic door device, since the motor and the controller are arranged in a blind manner, each door is required to be installed in the automatic door device. The work of installing at the door opening and the work of disposing the motor and the controller blindly
This had to be done individually at the installation site.

[0005] For this reason, the number of steps of the installation work has increased, and the installation work of the automatic door device has required a long time, and the labor of the operator has also increased.

Further, as described above, a double door type automatic door apparatus generally uses two doors having substantially the same configuration. Therefore, in order to solve the above problem, it is necessary to assemble a motor and a controller for each door, make each of the two doors self-propelled, and have a configuration in which each can slide independently.

[0007] However, in this configuration, the motor and the controller, which have been provided at one place in the past, are provided at two places, which not only increases the cost but also increases the cost.
These assembling operations require a lot of time and labor and are not practical.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to reduce the number of man-hours required for installation in a door opening with respect to a double-opening type automatic door device, and to further reduce the number of driving operations. It is an object of the present invention to provide a configuration capable of satisfactorily opening and closing each door only by disposing a power source and a control means at one place.

[0009]

Means for Solving the Problems-Summary of the Invention-In order to achieve the above object, according to the present invention, only one of the doors constituting the double-door automatic door device is constituted by a self-propelled type, and Linked with other doors when running by itself. Thereby, it is possible to realize a double door automatic door device with one drive source without having to provide the drive source seamlessly, that is, without having to install the drive source at the installation site. I have. In another invention, only one of the doors is provided with control means for controlling the opening and closing of the door, so that the work of attaching the control means at the installation site seamlessly is unnecessary.

-Solution Means- Specifically, a first solution means taken by the present invention is that the double door automatic door device is constituted by a drive door and a free door.
The drive door is capable of self-running between an open position and a closed position along an opening / closing track so as to open and close the door opening. The power of the drive door is transmitted to the free door, and the free door is movable between an open position and a closed position along an opening / closing track in conjunction with the movement of the drive door.

According to this specific matter, when the drive door moves in the opening direction or the closing direction, the moving power is transmitted to the free door. Thereby, the free door also moves in the opening direction or the closing direction in synchronization with the driving door. For this reason, both doors can be moved by only one drive source incorporated in only the drive door. When installing the door, a drive door in which a drive source is incorporated in advance is installed at the door opening, and a free door is installed in the same manner. That is, individual installation work for mounting the drive source in a blind manner at the door opening is not required at the installation site, and the workability is good.

The second solution is based on a double-door automatic door device provided with two doors movable between an open position and a closed position along an opening / closing track so as to open and close the door opening. . In this double door automatic door device, only one of the two doors is provided with a drive source for generating a driving force for moving the door along the opening and closing path. Further, the door provided with the drive source and the other door are connected by a loop belt so that the other door moves along the opening / closing track with the movement of the door provided with the drive source.

[0013] A third solution is a driving means for applying a driving force for moving only one of the two doors constituting the double door automatic door device along the opening and closing path. Is provided. Only the door to which the driving force is applied is provided with a control unit for controlling the driving unit. Then, the door to which the driving force is applied is connected to the other door by a loop belt so that the other door moves along the opening / closing track with the movement of the door to which the driving force is applied. I have.

According to these specific items, when one of the doors moves on the opening / closing track, the loop belt connected to this door runs. With this travel, the other door also moves on the opening and closing track. Thus, in these solutions, 1
The opening and closing operation of the two doors can be performed in conjunction with one drive source or drive means. Further, in the third solution, since the control means is provided on one of the doors, a separate mounting operation for mounting the control means on the door opening or the like is unnecessary at the installation site. 4th to 6th
The solution of the present invention embodies a configuration of an opening / closing mechanism provided for moving a door provided with a drive source along an opening / closing track. That is, the fourth solution is the second solution, wherein the opening / closing mechanism includes an output pulley that is rotationally driven by a drive source, and a traveling device that extends parallel to the extension direction of the opening / closing track and is wound around the output pulley. And an idle pulley disposed on both sides of the output pulley to displace the traveling belt in a direction of winding around the output pulley.

According to a fifth aspect of the present invention, in the second aspect, the opening / closing mechanism includes a pinion gear that is rotationally driven by a drive source, and a rack that extends parallel to the extension direction of the opening / closing track and meshes with the pinion gear. I am preparing.

According to a sixth aspect of the present invention, in the second aspect, the opening / closing mechanism includes a rubber roller that is rotationally driven by a driving source. Then, the outer peripheral surface of the rubber roller is brought into contact with the opening edge component of the door opening.

[0017] These specific items make it possible to move the door smoothly along the opening and closing path. In particular, according to the fifth solution, since the rack and pinion mechanism that does not cause slippage is employed, the movement of each door can be performed stably. In addition, according to the sixth solution, no special means is required on the door opening side, so that the number of parts can be reduced.

According to a seventh aspect of the present invention, the driving means is specifically specified. In other words, in the third solving means, the driving means includes a stator provided on one side and a movable element provided on the other side of the opening edge components of the one door and the door opening. It is composed of a linear motor.

The opening / closing mechanism of each of the above-described solutions converts the rotary motion into a linear motion to move the door. According to the seventh solution, it is not necessary to change the direction of movement, so that the door can be moved efficiently.

The drive door 2 has a motor 26 as a drive source connected to a speed reducer 25 and a control unit 27 as control means for controlling the motor 26 at the upper end of its internal space. ing. An output shaft 26a of the motor 26 extends upward, and an output pulley 2
6b is fixed. An idle shaft 2 extending upward from the upper frame 21 is provided on both left and right sides of the output pulley 26b.
8 and 28, and idle pulley 28
a, 28a are rotatably mounted via bearings (not shown).

The traveling belt 6 is wound around each of the pulleys 26b, 28a, 28a. Specifically, as shown in FIG. 3 (a plan view of the arrangement of the pulleys 26b, 28a, 28a), the direction in which the traveling belt 6 is wound around the output pulley 26b (the belt is wound from the lower side in FIG. 3). ) And the direction in which the traveling belt 6 is wound around the idle pulleys 28a, 28a (wrapped around from above in FIG. 3). As a result, a large contact area between the output pulley 26b and the traveling belt 6 is secured, and the output pulley 26b and the traveling belt 6
The occurrence of slip between them is prevented.

The toothed belt 71 connects the driving door 2 and the free door 3, and the two are linked. A specific configuration will be described with reference to FIG. 4 (a is a front view showing a connection state between each door 2, 3 and the toothed belt 71, and b is a perspective view thereof).

As shown in FIG. 4, the toothed pulley 7,
Upper part 72 of the toothed belt 71 stretched around 7
(Hereinafter, referred to as an upper span) and a lower portion 73 (hereinafter, referred to as an upper span).
The upper span 72 is connected to the drive door 2 via the connecting bracket 29, and both ends 73a, 73a located on the lower span 73 are free via the pair of connecting brackets 35, 35. It is connected to the door 3.

As described above, since the doors 2 and 3 are connected to the different spans 72 and 73 of the toothed belt 71, when the drive door 2 moves in the opening direction (left direction in the figure),
The free door 3 also moves in the opening direction (right direction in the figure), and conversely,
When the drive door 2 moves in the closing direction (right direction in the figure), the free door 3 also moves in the closing direction (left direction in the figure).

Further, the automatic door device includes a start sensor and a safety sensor (not shown). These sensors are
Mounted on blinds, cubicles or doors. The activation sensor includes a non-contact sensor and a touch sensor, and detects an approach of a human body and a request to open a door. When the activation sensor detects the approach of a human body or the like, a detection signal is transmitted to the control unit 27, and the control unit 27
With the control operation described above, the motor 26 is driven by a predetermined rotation amount to move the doors 2 and 3 in the opening direction. On the other hand, the safety sensor detects the presence of a human body at the door opening A. While the safety sensor is detecting the presence of a human body, the detection signal is transmitted to the control unit 27 to prevent the doors 2 and 3 from moving in the closing direction.

-Description of Installation Operation of Automatic Door Device- Next, the operation of installing the above-described automatic door device 1 will be described. The drive door 2 and the free door 3 are each previously manufactured in a production factory. In other words, the free door 3 has the roller brackets 32, 32 and the connection brackets 35, 35 attached to the upper frame 31. The drive door 2 houses the reduction gear 25, the motor 26, and the control unit 27 therein. With the roller brackets 22, 22, the connection bracket 29, and the idle pulleys 28a, 28a attached, the automatic door device 1 is carried to the installation site. Rollers 23 and 33 are rotatably mounted on the roller brackets 23 and 32, respectively.

In the installation work of the doors 2, 3, first,
The rollers 23 and 33 provided on the roller brackets 22 and 32 of the doors 2 and 3 are mounted on the bottom wall 52 of the guide rail 51, and the upper ends of the doors 2 and 3 are suspended on the guide rail 51.

reference). As a result, the traveling belt 6 is wound around the output pulley 26b in a state where occurrence of slip with the traveling belt 6 is prevented. Thus, the automatic door device 1 has been installed in the door opening A.

Next, the operation of the automatic door device 1 installed in the door opening A as described above will be described.

In a state where the doors 2 and 3 are closed (see FIG. 1), when the activation sensor detects the approach of a human body,
The control unit 27 operates to drive the motor 26 by a predetermined rotation amount. By this driving, the output pulley 26 travels on the traveling belt 6, and accordingly, the driving door 2 slides in the opening direction (left direction in FIG. 2). This drive door 2
, The free door 3 connected to the drive door 2 by the toothed belt 71 also slides in the opening direction (rightward in the figure). Thus, as only one door (drive door 2) moves, the other door (free door 3) interlocks.

In the open state of the doors 2, 3, while the safety sensor detects the presence of a human body, the doors 2, 3 are prevented from moving in the closing direction.

Thereafter, when the state in which the activation sensor does not detect a human body continues for a predetermined time, the control unit 27 operates again, and the motor 26 is driven in the opposite direction by the predetermined rotation amount. By this driving, the output pulley 26b travels on the traveling belt 6, and accordingly, the drive door 2 slides in the closing direction (rightward in the drawing). In conjunction with the sliding movement of the drive door 2, the free door 3 also slides in the closing direction (left direction in the drawing). Thus, also in the closing operation, the other door (free door 3) is linked with the movement of only one door (drive door 2).

-Effects of Embodiment- As described above, in the present embodiment, only the drive door 2 is provided with the motor 26 as a drive source and the control unit 27 as control means, and the drive door 2 is driven by itself. The driving power of the driving door 2 is transmitted to the free door 3 by a toothed belt 71. Therefore, one motor 2
The doors 2 and 3 can be moved only by the control unit 6 and the control unit 27. Also, the motor 26 and the control unit 27
It is not necessary to perform the work for attaching the camera seamlessly at the installation site. Therefore, the installation workability is good.

The motor 26 has an output shaft 26a extending in the vertical direction. For this reason, the required dimension in the thickness direction of the door (the dimension in the thickness direction of the door internal space) may be smaller than when a motor whose output shaft extends in a direction perpendicular to the door surface is employed. For this reason, the drive door 2 in which the motor is built can be realized without increasing the thickness of the door. Therefore, the appearance of the drive door 2 can be satisfactorily secured.

-Other Embodiments- In the embodiment described above, the opening / closing mechanism 4 for moving the drive door 2 along the opening / closing trajectory is constituted by the output pulley 26b, the idle pulley 18a, and the traveling belt 6. The present invention is not limited to this. Hereinafter, modified examples of the opening and closing mechanism 4 will be described.

First, the one shown in FIG. 5 employs a rack and pinion as the opening and closing mechanism 4. That is, a pinion gear 81 is attached to the output shaft 26a of the motor 26 instead of the output pulley 26b, and a rack 82 is provided instead of the traveling belt 6. Accordingly, the pinion gear 81 rotates while meshing with the rack 82 with the driving of the motor 26, and the drive door 2 slides. According to this configuration, since the rack-and-pinion mechanism that does not cause slippage is employed, the moving operation of each door can be performed stably. The amount of movement of the doors 2, 3 according to the amount of rotation of the motor 26 can be accurately obtained.

FIG. 6 shows another modification of the opening / closing mechanism 4. As shown in FIG. 6, the output pulley 26b
Instead, a rubber roller 83 is attached to the output shaft 26a of the motor 26. The outer peripheral surface of the rubber roller 83 is in contact with the inner wall surface 53 of the blind 5 which is an opening edge structure of the door opening A. As a result, the rubber roller 83 rotates with the driving of the motor 26, the rubber roller 83 travels along the inner wall surface of the blind 5, and the drive door 2 slides (see the arrow in FIG. 6).

FIG. 7 employs a linear motor 9 as a driving means for generating a driving force for driving the driving door 2. That is, the stator 91 is attached to the inner wall surface 53 of the blind 5.
, While a mover 92 is attached to a portion of the drive door 2 that faces the stator 91. Thus, for example, when the stator 91 is energized, the linear motor 9 is driven and the drive door 2 slides (see the arrow in FIG. 7).

It should be noted that, in the above-described embodiment and modified examples, 2
Of the two doors 2, 3, the door located on the left side in FIG. 1 is the drive door 2, and the right door is the free door 3. The present invention is not limited to this, and the door located on the right side in FIG. 1 may be configured as a drive door, and the left door may be configured as a free door.

The automatic door device 1 according to the present invention can be used not only for homes but also for various uses such as stores and offices.

The means for transmitting the moving power of the drive door 2 to the free door 3 is not limited to the toothed belt 71. For example, a rope or a chain can be adopted.

The opening / closing mechanism 4 is not limited to the above-described one, and various mechanisms can be adopted.
