Abstract

PROBLEM TO BE SOLVED: To improve the safety of turning of a turning rail by providing a traveling device or a partition panel with a traveling distance detecting means and a censor for detecting a detected element, once resetting the traveling distance data simultaneously with the stop of the traveling device and then detecting again the subsequent traveling distance data, taking the detected element as a starting point by the traveling distance detecting means when the sensor detects the detected element. SOLUTION: When a traveling device 2 which enters a turning rail 10 through a rail 1 is detected by a sensor 18, it is stopped by a microcomputer. Simultaneously the traveling distance data up to this time detected by a rotary encoder 12 is once reset. If the traveling device 2 protrudes over the proper stop position due to the entering force, the distance data for protrusion over the proper stop position is recorded by the rotary encoder 12, and the traveling device 2 is returned by the recorded data distance.

Description

Detailed Description of the Invention

[0001]

The present invention relates to an electric partitioning device,
In particular, it relates to changing the direction of the traveling device in the turning rail.

[0002]

2. Description of the Related Art Conventionally, there is provided a self-propelled partition device capable of changing the traveling direction of each partition panel by pivoting the pivoting rail while the traveling device is located in the pivoting rail. In order to stop the traveling device at an appropriate stop position in the turning rail, a sensor is appropriately provided on the turning rail, and the sensor detects the traveling device to stop the traveling of the traveling device. It has been known.

[0003]

However, in such a device, although the traveling device can be temporarily stopped at the proper position in the turning rail, the traveling device does not turn the turning rail before or during turning. It sometimes moved from the proper stop position. Then, the control device cannot recognize the movement of the traveling device, and the turning rail turns in a state in which the traveling device is displaced from the proper stop position, and the partition panel swings greatly as the turning rail turns. In some cases, the end of the traveling device protrudes outside the turning rail, which hinders the turning of the turning rail.

Also, in such a conventional device, if a control method is devised, a command for stopping the movement of the traveling device is issued by using a sensor or the like for stopping the traveling device at an appropriate position in the turning rail. Although it is possible to put it out, it is not possible to recognize the moving direction and moving distance of the traveling device after that, so return the traveling device to the proper position in the turning rail and turn the turning rail in a safe state. I couldn't do it.

The present invention has been made in view of these problems, and it is an object of the present invention to provide an electric partitioning device capable of safely and reliably changing the direction of a traveling device by a rotating rail. .

[0006]

In order to achieve the above object, an electric partition device according to the present invention is provided with any one of the rails at an intersection of a partition rail and a storage rail fixed to a ceiling and orthogonal to each other. Rotating rails selectively aligned in a straight line are provided on the ceiling so as to be swivelable by a vertical drive shaft that interlocks with a motor, and a traveling device provided on a plurality of partition panels so as to be rotatable around a vertical axis, By mounting the partition panels so that they can be self-propelled along the rails, the partition panels are movably hung below the rails, and in the state where the traveling device is located inside the rotary rails, In a self-propelled partition device in which the traveling direction of each partition panel can be changed by rotating the partition panel, a traveling distance detecting means and a rotating rail are provided on the traveling device or the partition panel. A sensor provided at the traveling device stop position for detecting the detected object is provided, and when the sensor detects the detected object, the traveling distance data is once reset at the same time when the traveling device is stopped, and then the detected object is detected again. It is characterized in that the traveling distance detecting means detects the subsequent traveling distance data as a starting point. According to this feature, when the traveling device stopped at the proper stop position in the turning rail moves from the proper stop position before or during the turning of the turning rail, the traveling distance data is reset. Since the running distance detecting means detects the running distance data starting from the detected object, it is possible to recognize the moving direction and the distance which occur as a deviation of the running device, and return the running device to the proper position. Therefore, the turning rail can be turned more safely and reliably.

In the electric partition device of the present invention, when the traveling direction of each partition panel is changed by rotating the rotating rail while being positioned inside the traveling device rotating rail, the traveling device for the rotating rail. After the traveling device is temporarily stopped at the stop position, when movement of the traveling device from the stop position is detected by the traveling distance detecting means, turning of the turning rail is stopped, and the traveling device is returned to the proper stop position. It is preferable that the turning of the turning rail is restarted. By doing so, it is possible to more safely and surely change the direction of the traveling device by turning the turning rail.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 1 shows the entire system of an electric partition device as an embodiment of the present invention.
Is a rail fixed to the ceiling, 2 is a traveling device that travels in the rail, and 3 is a panel suspended from the traveling device 2. A drive unit 4 having a built-in motor and the like for driving the traveling device 2 is installed in the panel 3 and is connected to a microcomputer 5 provided as an internal control device in the panel 3. .

The microcomputer 5 is connected via a communication unit 6 to a power / signal wiring 7 arranged in the longitudinal direction of the inner surface of the rail 1, and the power / signal wiring 7 is provided.
More power and signals can be sent and received.

Reference numeral 9 denotes a host computer as an external control device for integrally controlling each of the panels 3, which is connected to the power / signal wiring 7 through a communication unit 8 and further provided at a predetermined position in the rail 1. Traveling device 2
Is connected to a turning rail drive unit 11 of a turning rail 10 for changing direction. Here, the turning control of the turning rail 10 is performed by the host computer 9.

As shown in FIG. 2, in particular, the traveling device 2 is internally provided with a rotary encoder 12 as a traveling distance detecting means so that the traveling device 2 itself can measure traveling distance data. It has become. A gear 13 is provided at the tip of the rotary encoder 12, and the gear 13 is used for the axle 1 of the wheel 14 of the traveling device 2.
Since it is meshed with the gear 16 fixed to the wheel 5,
The traveling distance of the traveling device 2 can be measured by the number of revolutions of 4. Although not shown in the figure, the traveling device 2 has a drive device and the like appropriately incorporated therein in addition to the rotary encoder 12.

On the upper surface of the traveling device 2, there is provided a sensor 18 provided on the side surface of the rotary rail 10 for detecting the detected object 17, and the traveling object 2 is detected while the traveling device 2 is traveling. Is detected by the sensor 18, the microcomputer 5 stops the traveling device 2 and resets the traveling distance data measured by the rotary encoder 12.

In the electric partition device thus constructed, the microcomputer 5 mounted in each panel 3 receives the input signal from the sensor and the communication information from the host computer 9 to judge the situation. After that, when the communication with the host computer 9 is performed via the communication units 6 and 8 and an appropriate command signal is received, the traveling of the traveling device 2 can be started and stopped via the drive unit 4. Has become.

For example, when the traveling device 2 reaches before the turning rail 10, the microcomputer 5 turns the turning rail 10 to the host computer 9 via the communication units 6 and 8 based on the information received by the sensor appropriately. A signal such as a request is sent and a command is given to the traveling device 2 to wait at that position, and the traveling device 2 is restarted when the turning rail 10 is stopped at the proper position.

Since the microcomputer 5 can program and store the traveling history data of its own panel 3 (traveling device 2) in advance, each panel 3 is actually moved at the construction site and many of the panels 3 are moved. By registering the traveling history data of each panel 3 itself according to the partition pattern, each panel 3 can be automatically moved to the partition position.

Here, when the traveling device 2 traveling in the rail 1 as the partition rail changes its direction via the rotating rail 10 and moves into the rail 1a as the storage rail orthogonal to the rail 1, the traveling device 2 moves. The operation of the traveling device 2 and the turning rail 10 will be described with reference to FIGS.

The traveling device 2 which has entered the inside of the turning rail 10 from the inside of the rail 1 on the right side in FIG. 2 has a detected body 1 provided at a substantially central position of the turning rail 10 as described above.
When 7 is detected by the sensor 18, it is stopped by the microcomputer 5 (see FIG. 3 (3a)). At the same time, the traveling distance data detected so far by the rotary encoder 12 is once reset (cleared).

As described above, when the traveling device 2 protrudes from the proper stop position where the rotary encoder 12 is reset due to the momentum of the approach, the distance data that protrudes from the proper stop position is the rotary encoder 12.
Is recorded by the microcomputer 5, the traveling device 2 is moved back by the microcomputer 5 by the recorded distance data (see FIG. 4).

When the traveling device 2 is returned to the proper stop position and recognizes that the traveling device 2 is stopped, the microcomputer 5 sends a turning request signal for the turning rail 10 to the host computer 9 as described above, and therefore the turning operation is performed. The turning of the rail 10 is started.

Here, by turning the turning rail 10,
When the traveling device 2 is moved by a certain factor such as centrifugal force due to rotation and moved by the distance L in the direction of the arrow as shown in FIG. 3B, the microcomputer 5 indicates that the rotary encoder 12 has been activated. Is recognized by the microcomputer 5, the microcomputer 5 sends a turning stop request signal for the turning rail 10 to the host computer 9, and the turning rail 1
The turning of 0 is stopped. The presence or absence of movement of the traveling device 2 by the microcomputer 5 at this time may be recognized by the positional deviation between the sensor 18 and the detected body 17.

Further, at the same time when the turning rail 10 is stopped, the microcomputer 5 moves the traveling device 2 back by the moving distance L, and when the turning rail 10 is stopped at the proper position, the turning rail 10 is turned again (FIG. 3). (See (c)).

After repeating this operation, when the turning rail 10 is turned to the horizontal position with respect to the rail 1a (two-dot chain line position in FIG. 3 (c)), the microcomputer 5 moves the traveling device 2 to the rail. Enter into 1a. This time,
Since the program for sending the signal for returning the traveling device 2 to the reverse direction is canceled, the traveling device 2 is not returned to the reverse direction even if the rotary encoder 12 is operated.

Further, as described above, the moving direction of the traveling device 2 caused by the turning of the turning rail 10 is indicated by the rotary encoder 12 as a plus or minus value from the time of being reset, so that it can be easily recognized.

The embodiments of the present invention have been described with reference to the drawings. However, the specific configuration is not limited to these embodiments, and even if there are changes and additions without departing from the gist of the present invention. Included in the invention.

For example, in the embodiment, the turning of the turning rail 10 is stopped by the movement of the traveling device 2. However, when the movement of the traveling device 2 is recognized, the correction can be made earlier. If it is, there is no need to stop.

[0026]

The present invention has the following effects.

(A) According to the invention of claim 1, the traveling device stopped at the proper stop position in the turning rail moves from the proper stopping position before or during turning of the turning rail. In the case where the traveling distance data has been reset, the traveling distance detection means detects the traveling distance data starting from the object to be detected, so that it is possible to recognize the moving direction and the distance which are caused by the displacement of the traveling device. Can be returned to the proper position. Therefore, the turning rail can be turned more safely and reliably.

(B) According to the second aspect of the invention, the direction of the traveling device can be changed more safely and surely by turning the turning rail.
