Abstract

PROBLEM TO BE SOLVED: To prevent a sensor trouble and securely accelerate or decelerate a subsequent panel on the basis of the distance between a preceding panel and the subsequent panel and prevent the adjacent panels from colliding with each other and breaking. SOLUTION: A partition panel 39 is hung down and supported by drive runners 13, 14 traveling along a rail 11. A number of photoelectric sensors to detect a dog provided in the drive runner are attached along the whole part in the longitudinal direction of the rail 11. When respective partition panels 39 transfer along the rail 11, the number of photoelectric sensors 44 (the number of nondetection sensors) varies, which are positioned between the photoelectric sensors 44 detecting the drive runner 13 of the preceding panel 39 and the photoelectric sensors 44 detecting the drive runner 13 of the subsequent panel 39. The subsequent panel 39 is accelerated or decelerated or stopped on the basis of the number of nondetection sensors. Since respective sensors 44 are attached to the rail 11, the vibratory transfer to respective photoelectric sensors during the movement of the partiton panels is prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive control device for a panel such as a partition panel.

[0002]

2. Description of the Related Art Conventionally, a large space such as a wedding hall is divided into small spaces according to the number of employees by a partition panel disclosed in Japanese Patent Publication No. Hei 7-13425, for example. That is, a rail of a predetermined length is provided on a ceiling of a wedding hall or the like and extends in a direction orthogonal to a wall surface inside the wedding hall, and a drive runner provided with an electric motor suspends an upper end of the partition panel on the rail. A plurality is provided in a state supported below. When the electric motor of the drive runner is driven, the drive runner travels along the rail, and the partition panel moves in synchronization with the drive runner.

A sensor for detecting the distance between the partition panel and the preceding partition panel is provided on the side of the partition panel in the moving direction. This sensor can transmit a sound wave or the like toward the preceding partition panel and can receive a sound wave reflected by the partition panel. Then, the sensor detects a distance between the two panels based on a time from when the sound wave is transmitted to when the sound wave is received, and outputs a detection signal corresponding to the detected distance.

[0004] When partitioning the wedding hall into small spaces by the partition panels, each partition panel is sequentially moved toward the wall surface of the wedding hall. When the leading partition panel comes into contact with the wall surface and stops, the subsequent partition panel approaches the partition panel, and the sensor of the subsequent partition panel outputs a detection signal corresponding to the distance between the two panels. The runner electric motor that suspends and supports the subsequent partition panel is driven and controlled based on a detection signal from the sensor. That is, as the distance between the two panels becomes smaller, the number of revolutions of the electric motor for the runner is made smaller, and the moving speed of the subsequent partition panel is made smaller. The subsequent partition panel comes into contact with the leading partition panel and is gradually decelerated so that the moving speed becomes zero at the same time.

[0005] After the subsequent partition panel comes into contact with the leading partition panel and is stopped, the subsequent partition panel further contacts the preceding partition panel in the same manner as described above. Stopped. The stopped partition panels divide a large space such as a wedding hall into a small space.

The present invention has been made to solve the above problems, and a first object of the present invention is to prevent a failure of a sensor. A second object is to reliably decelerate or accelerate the succeeding panel based on the distance between the preceding panel and the succeeding panel.

A third object is to prevent adjacent panels from colliding with each other and being damaged.

[0009]

To achieve the above object, according to the first aspect of the present invention, there is provided a moving means for moving a plurality of panels along the same predetermined trajectory, and a moving means for detecting the panels. A large number of sensors provided at predetermined intervals along a predetermined trajectory on which the panel moves,
Control means for controlling the moving means is provided based on the number of sensors located between the sensor that has detected the panel and the sensor that has detected the panel next to the panel.

[0010] In the invention according to claim 2, the control means is configured to switch the following panel when the preceding panel and the succeeding panel are close to each other and the number of sensors between the sensors detecting the both panels is less than a predetermined number. The moving means is controlled so that the preceding panel and the succeeding panel are separated from each other so that when the number of sensors between the sensors for detecting the two panels exceeds a predetermined number, the following panel accelerates. Is controlled.

According to a third aspect of the invention, when the preceding panel comes into contact with the succeeding panel and the number of sensors between the sensors for detecting the two panels reaches a predetermined number, the following panel is controlled. The moving means is controlled so as to stop.

That is, according to the first aspect of the present invention, each panel is moved along the same predetermined track by the moving means.
The moving panel is detected by any of a large number of sensors provided at predetermined intervals along the predetermined track. Then, the control means controls the moving means such that the panel performs deceleration, acceleration, stop, or the like based on the number of sensors located between the sensors that have detected the adjacent panels.

According to the second aspect of the present invention, in addition to the operation of the first aspect, the control means may include a sensor between the sensors that detect the two panels by approaching the preceding panel and the succeeding panel. When the number is equal to or less than the predetermined number, the moving means is controlled so that the subsequent panel is decelerated. Further, the control means controls the moving means so as to accelerate the succeeding panel when the preceding panel and the succeeding panel are separated from each other and the number of sensors between the sensors detecting the both panels becomes equal to or more than a predetermined number. .

According to the third aspect of the present invention, the first or second aspect is provided.

Next, the operation of the drive control device for a partition panel configured as described above will be described. In order to partition a large space such as a wedding ceremony or the like into a small space with each partition panel 39, the AC geared motor 25 is driven to drive the drive runners 13 and 14 along the rails 11 so that each partition panel 39 is divided into a wedding hall. Are sequentially moved toward the wall surface. Since each photoelectric sensor 44 is provided on the rail 11, vibration generated in the partition panel 39 when the partition panel 39 moves is not transmitted to each photoelectric sensor 44.

When the speed of the preceding partition panel 39 decreases due to a failure or the like, and the distance between the partition panel 39 and the subsequent partition panel 39 becomes 200 mm or less, the distance between the two panels 39 becomes smaller. Is gradually reduced as becomes smaller. Also, during the movement of each partition panel 39, the preceding partition panel 39
When the distance between the first partition and the subsequent partition panel 39 becomes 200 mm or more, the subsequent partition panel 39 is gradually accelerated as the distance between the two panels 39 increases.

When the distance between the fixed partition panel 39 and the subsequent partition panel 39 becomes 200 mm or less, the subsequent panel 39 immediately stops when the AC geared motor 25 of the drive runners 13 and 14 is stopped. The speed is gradually reduced until the moving speed is reached.
Further, when the two panels 39 come into contact with each other, the succeeding panel 39 is stopped and fixed at that position. Thereafter, the partition panel 39 that is further succeeding than the succeeding panel 39 is fixed in a state of being sequentially in contact with the partition panel 39 fixed earlier.

Then, when the number of non-detected sensors becomes N1 or less, the subsequent partition panel 39 is decelerated, and when the number of non-detected sensors becomes N1 or more, the subsequent partition panel 39 is accelerated. Therefore, the subsequent partition panel 39 can be reliably decelerated or accelerated based on the distance between the preceding partition panel 39 and the subsequent partition panel 39.

(C) When the preceding panel 39 and the succeeding panel 39 come into contact with each other and the number of non-detection sensors becomes N2, the movement of the succeeding panel 39 is stopped. Therefore, adjacent partition panels 39 collide with each other, and the collision causes the two panels 39 to collide with each other.
Can be prevented from being damaged.

(D) As the number of non-detection sensors decreases or increases by one from N1, the subsequent partition panel 39 is gradually decelerated or accelerated. Acceleration can be performed smoothly.

(E) The succeeding panel 39 approaching the preceding panel 39 is the AC geared motor 2 of the succeeding panel 39.
