As shown in FIG. 6, at the intersection of the partitioning rails 02 fixed to the ceiling 01 at right angles to each other, a rotating rail 03 that is selectively linearly aligned with any one of the rails is provided with a vertical axis 010 from the driving device 05. , For example, can be turned horizontally by 90 °, and a plurality of partition panels 06 are provided with a drive shaft 0
The traveling device 08 provided rotatably around the
6 is provided so as to be able to run along each of the rails by rotating the drive shaft 07 via a geared motor (not shown) fixed in the traveling rail 6, and a traveling device 08 is mounted inside the rotating rail 03. In some cases, the turning rail 03 is turned while it is positioned.

The partitioning rail 02 and the rotating rail 03 are formed in a channel shape by an upper wall 020, left and right side walls 021 and a bottom wall 023 having a groove 022 formed in the rail longitudinal direction.

A rotating shaft 012 having a shaft hole 012a at the center is fixed to the center of the upper surface of the rotating rail 03, and the lower end of the vertical shaft 010 cannot be relatively rotated through the key 016 in the shaft hole 012a. Is fitted. Note that this rotation axis 0
Numeral 12 is inserted through the through hole 013a of the bottom plate 013 and hangs down, and a pair of upper and lower bearings 015 is inserted into a cylindrical holding member 014 in which an outward flange portion 014a is bolted to the upper surface of the bottom plate 013. It is fitted rotatably.

[0005]

However, in such a turning rail device of a partition device, when the traveling device 08 does not enter the turning rail 03,
When the traveling device 08 is stopped at the center of the rotating rail 03, there is no problem because the rotating rail 03 can be balanced around the vertical axis 010. However, as shown in FIG. When the traveling device 08 enters or exits the rail 03, or when the traveling device 08 is displaced from the center position of the rotating rail 03 while the rotating rail 03 is turning, the panel 06 is particularly large. When there is weight, an eccentric load about the vertical axis 010 is applied to the rotating rail 03, and the rotating rail 03 itself may be bent or the rotating rail 03 may be inclined by the amount of play of the bearing 015.

In such a case, the side wall 0 of the rotating rail 03

There is a problem that the rotation of the rotating rail 03 is hindered if the interference occurs when the rotating rail 03 rotates, particularly when the rotating rail 03 rotates.

Therefore, it is conceivable to increase the gap between the opposing portions of the two rails 02 and 03 so that the above-mentioned interference does not occur. However, when the gap becomes large, the roller of the traveling device 08 is inserted into the gap. In some cases, the traveling movement of the traveling device between the rails during normal operation may be hindered.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a rotary rail device as a first embodiment of the present invention. Numerals 1 and 2 denote partition rails disposed orthogonally to each other on the lower surface of the ceiling, and reference numeral 3 denotes a pivot rail rotatably disposed at the intersection of the partition rails 1 and 2.

In the present embodiment, the rotating rail 3
Is horizontally turned by 90 °, so that the panel traveling along the storage rail can be selectively delivered to either of the partitioning rails 1 and 2.

Reference numeral 4 denotes a traveling device which travels in each rail by being supplied with power from a power supply / signal bar (not shown) provided above each rail. (See FIG. 5).
Since the traveling device 4 is described in detail in Japanese Patent Application Laid-Open No. Hei 6-335661 filed by the present applicant, a detailed description thereof will be omitted. I do. A zone Z indicated by oblique lines in the drawing indicates a traveling zone of the traveling device 4.

Each of the rails 1, 2, 3 has a top wall 5,
A left and right side wall 6 and a bottom wall (not shown) having a groove formed in the longitudinal direction of the rail are formed in a channel shape.

Each partition rail 1 on the rotating rail 3
The two end portions E as opposed portions to the two end portions F are formed in an arc shape with a radius R1 about the center point O of the rotation of the rotating rail 3.

The shape of an end F of the right partitioning rail 2 facing the end E of the turning rail 3 in the right side in the drawing is farther from the center point O of the turning rail 3, that is, the left side in the drawing. It is formed in an arc shape with a radius R2 centered on the position point O1.

Also, an end F of the left partitioning rail 2 in the figure.
Is an arc shape centered on the point O3, and the end view F of the upper and lower partition rails 1 in the figure is a point O2,
Each is formed in an arc shape centered on O4.

Each of the partition rails 1 and 2 and the pivot rail 3 whose ends are formed in a predetermined shape as shown in FIG.
As shown in FIG. 5, when the rotating rail 3 is selectively aligned with the partition rail 2 (or the partition rail 1) in a straight line, a predetermined gap is formed between the ends E and F facing each other. Provided.

The shapes of the ends E and F of each rail are as follows.
By being formed in the shape of an arc having a different radius of curvature, a gap L1 between the ends E and F at a substantially central portion in the left-right direction toward the longitudinal direction of the rail, the distance between the ends E and F on the left and right side walls 6 side. The gap L2 is large.

Therefore, the arcs of the end F of the partition rail 2 and the end E of the pivot rail 3 are formed as concentric arcs having different diameters, and the pivot rail 3 is connected to the partition rail 2 (or the partition rail 1). In the case where the alignment is selectively performed in a straight line, the gap L applied to the traveling zone Z of the traveling device 4 is determined.
The rotating rail 3 and the partitioning rails 1 and 2 are provided such that the traveling roller 1 does not hinder the traveling roller from entering the gap when traveling between the rails of the traveling device 4, and the gap L1 = L2. Since the gap between the end 6a of the side wall 6 of the rotating rail 3 and the end 6b of the side wall 6 of the partitioning rail 2 that are opposed to each other is larger,
Side wall 6 of the rotating rail 3 when the shaft is bent or inclined
Between the end 6a of the partition rail 2 and the end 6b of the side wall 6 of the partition rail 2 can be effectively prevented.

When the rotating rail 3 is bent or inclined, the end E at the substantially central portion in the left-right direction toward the longitudinal direction of the rotating rail 3, that is, the ends of the upper wall 5 and the bottom wall are opposed to each other. Since it does not enter the space of the partition rail 2 and does not interfere with the end F of the partition rail 2, the gap L1 applied to the traveling zone Z of the traveling device 4 is smaller than L2 and between the rails of the traveling device 4. It is possible to keep the running rollers in the gap during the running movement without any trouble.

Also, as shown in FIG.
Even if the traveling device 4 is displaced from the center position for some reason during the rotation of the rail, and the rotation rail 3 is bent or inclined, the end of the side wall 6 of each of the rotation rails 3 facing each other during the rotation. 6a and the end portions 6b of the side walls 6 of the partition rail 2 do not interfere with each other.

Further, during the rotation, the end E at the substantially central portion in the left-right direction toward the longitudinal direction of the rotating rail 3, that is, the ends of the upper wall 5 and the bottom wall are connected to the side wall 6 of the partition rail 2.
Even when they face the end 6b, the gap between them is L2, so they do not interfere with each other.

FIG. 3 shows a second embodiment of the present invention. The end portions F of the partitioning rails 1 and 2 and the end portion E of the turning rail 3 in the present embodiment are formed in concentric arc shapes that are different from the center point O of the turning rail 3 only in radiuses R1 and R2. ing. And partition rail 1,
Notches 7 are formed at both ends of the second end F, respectively.

The notch 7 is formed in this way, and the gap L2 between the end 6b of the left and right side walls 6 of the partitioning rails 1 and 2 and the end 6a of the side wall 6 of the rotating rail 3 extends over the traveling zone Z. Since the gap can be provided to be larger than the gap L1, not only the same effects as in the above-described embodiment can be obtained, but also the gap can be easily adjusted while adjusting the gap only by performing simple processing on site. Further, in this case, the gap between the end E of the turning rail 3 and the end F of the partitioning rail 2 in the traveling zone Z can be maintained at substantially the same distance in the left-right direction. It is possible to reduce the gap between the traveling roller and the traveling zone.

FIG. 4 shows another embodiment of the present invention. End F of partition rails 1 and 2 in the present embodiment
The shape of the end E of the turning rail 3 is the same as the second embodiment described above, with the center at the center point O of the turning rail 3 and the radius R
Only R1 and R2 are formed in different concentric arc shapes. Notches 7 are formed at both ends of the end F of the partitioning rails 1 and 2, and the end E of the rotating rail 3 is formed.
Notches 8 are also formed at both end portions.

As described above, the notch may be formed at not only one of the partitioning rails 1 and 2 or the rotating rail 3 but also at both opposite ends of both rails. By doing so, the gap L2 between the end portions 6a and 6b of the side walls 6 of both rails is obtained.
Can be provided larger, and mutual interference can be more effectively prevented.

Although the embodiments of the present invention have been described with reference to the drawings, 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 second embodiment, the notch 7
Is provided only on the left and right side walls of the partition rails 1 and 2 facing the rotating rail 3, but may be provided only on the left and right side walls of the rotating rail 3 facing the partition rails 1 and 2. good. Further, in the second embodiment, the gap in the traveling zone Z of the traveling device is formed to be narrow overall, but it is not necessary that the entirety be particularly narrow. For example, if only the gaps of the traveling rollers of the traveling device are formed in the traveling zone portions, the gaps are formed wide in the central portion in the left-right direction (others) toward the longitudinal direction of the traveling zone Z. May be.

[0031]

The present invention has the following effects.

(A) According to the first aspect of the present invention, even when the rotating rail itself is bent or the rotating rail is inclined, the opposing portions of the rotating rail and the partition rail between the left and right side walls oppose each other. This makes it difficult to turn the rotating rail. In addition, since the gap between the facing portions of the rotating rail and the partition rail in the traveling zone of the traveling device is smaller than at least the gap between the left and right side wall facing portions of both rails, the distance between the rails of the traveling device in the normal state. There is no hindrance to traveling.

(B) According to the second aspect of the invention, the opposing portions of the two opposing rails are merely cut into arcs having different radii of curvature, respectively, so that the left and right side wall portions are closer than the traveling zone of the traveling device. The workability is good because the gap can be increased.

(C) According to the third aspect of the present invention, it is possible to easily provide the gap while adjusting the gap suitable for the mounting condition only by performing simple processing in the field. Further, in this case, it is possible to widen the width of the traveling zone in the left-right width direction and to keep the entire gap of the traveling zone narrow.
