BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a seismic isolation structure in which at least one floor portion can be displaced in the horizontal direction with respect to the other floor portion. And a power supply device for supplying a signal.

[0002]

2. Description of the Related Art Conventionally, as disclosed in, for example, Japanese Unexamined Patent Publication No. 9-315296, an automatic warehouse including a storage rack and a stacker crane has been disclosed. Articles are transferred in front of the automatic warehouse. There is provided a travel route for the article transport vehicle to be transported to the section. The article transport vehicle travels on the floor along the travel route via a plurality of wheels.

A guide rail for guiding the article transport vehicle along the traveling route is provided on the floor surface. Further, a feed rail for supplying electric power to the article transport vehicle is provided along the guide rail on the leg holding the guide rail. The article transport vehicle is provided with a pair of guide rollers that roll along both side surfaces of the guide rail and a current collector that contacts the power supply rail.

In the automatic warehouse as described above, as a countermeasure against an earthquake, as shown in FIG. 22, it is conceivable that the floor portion 113 on which the storage rack 111 and the stacker crane 112 are installed has a seismic isolation structure. That is, the floor portion 113 of the seismic isolation structure is supported on the foundation portion 114 via a plurality of seismic isolation devices 115, and the floor portion 11 of the adjacent non-seismic isolation structure is provided.
It is displaceable in the horizontal direction with respect to 6, so that it is possible to absorb shaking such as an earthquake.

As described above, one floor portion 113 having the seismic isolation structure and the other floor portion 1 adjacent to the floor portion 113 having the non-seismic isolation structure are provided.
16 and the guide rail is provided on one floor 1
One guide rail 117a provided on 13 and the other guide rail 11 provided on the other floor 116.
7b, and similarly, the power feeding rail includes one power feeding rail 118a provided on one floor 113 and the other power feeding rail 118 provided on the other floor 116.
It is divided into b and.

[0006]

However, in the above-mentioned conventional type, one floor portion 113 is replaced by the other floor portion 1 due to an earthquake or the like.
16 is displaced in the horizontal direction with respect to both floor parts 113, 11
When the gap 119 between 6 is reduced, one power supply rail 1
The end portion of 18a and the end portion of the other power supply rail 118b are pressed toward each other so that the two power supply rails 11
8a and 118b are damaged, and new feed rails 118a and 118b must be replaced each time.

Contrary to the above, when the gap 119 between the floors 113 and 116 is enlarged, one power supply rail 118a is formed.
Is separated from the end of the other power supply rail 118b, and a large gap exceeding the allowable range is generated between the end of one power supply rail 118a and the end of the other power supply rail 118b. At this gap, the current collector is the power supply rail 11
Since there is no contact with 8a and 118b, there is a problem that power supply to the article transport vehicle is stopped and the article transport vehicle cannot run.

Similarly, the above-mentioned problem also occurs in one guide rail 117a and the other guide rail 117b. As a measure for preventing the rail from being damaged as described above, for example, as shown in Japanese Patent Application Laid-Open No. 10-25003, the traveling rail body is divided by dividing the traveling rail at the boundary between one floor and the other floor. If a split rail is provided between the rails and the end surfaces of the rails are inclined, and the floor shakes in the rail length direction, the left and right rails will be flat with respect to the left and right rails. There is a configuration in which the traveling rail main body is displaced in the width direction with respect to the split rails when the floor portion swings in the width direction of the rails when the rails are opened in the shape of C.

However, in the above-mentioned conventional type, when an earthquake occurs, the left and right split rails open to the left and right running rail bodies in a C-shape in plan view, or the running rail body shifts in the width direction with respect to the split rails. There was a problem that the carriage could not run. It is an object of the present invention to provide a power supply device that can supply electric power or the like to a traveling body without being damaged even when one floor is displaced in the horizontal direction with respect to the other floor due to an earthquake or the like. .

[0010]

In order to achieve the above object, the first aspect of the present invention has a seismic isolation structure in which at least one floor portion can be displaced horizontally with respect to the other floor portion. A power supply device that is passed between floors and supplies electric power and signals to a traveling body, wherein fixed-side power supply members are provided on both floors, and movable-side power supply is provided between the fixed-side power supply members. Member is connected, the movable side power feeding member is divided in the length direction into a plurality of power feeding divided bodies, and these power feeding divided bodies are arranged side by side at a predetermined interval in the length direction and have a length. The movable member is configured to be movable in any direction, and a tension member for pulling the power feeding division bodies is provided between adjacent power feeding division bodies.

According to this, when one floor portion is displaced in the horizontal direction with respect to the other floor portion, each power feeding division body moves in the lengthwise direction, so that the space between adjacent power feeding division bodies is increased. The spacing will expand and contract. At this time, the adjacent power supply divisions are pulled by the tension members, and damage to the fixed-side power supply member and the movable-side power supply member is prevented. According to the second aspect of the present invention, the interval between the power supply divisions is pulled by a tension member,
They are kept at almost the same intervals.

According to this, since the intervals between the respective power supply divisions are substantially equal at all points, the intervals at some points become extremely larger than the intervals at other points, exceeding the allowable range. Non-uniform spacing is prevented. Therefore, when the traveling body travels, the current collector can surely pass through the space between the power feeding division body and the power feeding division body. As a result, it is possible to prevent a problem in which the above-mentioned interval becomes too large and the current collector does not come into contact with the power feeding division body and the power feeding to the traveling body is stopped.

According to the third aspect of the present invention, rails for supporting or guiding the traveling body are provided along the power supply member, and the rails include fixed rail bodies provided on both floors and one of the floors. It is composed of a fixed rail body and a movable rail body connected between the fixed rail body on the other floor, and the movable rail body is movable in the longitudinal direction and has a longitudinal axis passing through both ends as a center. Is horizontally rotatably connected to the fixed rail body, the fixed-side power feeding member is attached and fixed to each of the fixed rail bodies, and each power feeding divided body is provided on the movable rail body, and is fixed to the movable rail body. It is configured to be movable in the longitudinal direction.

According to this, when one floor portion is displaced in the horizontal direction with respect to the other floor portion, the movable rail body is displaced in the longitudinal direction or horizontally pivoted about the longitudinal axis. The movable rail body and the fixed rail body are prevented from being damaged.
In the fourth aspect of the present invention, the fixed rail body and the movable rail body are connected by inserting connecting pins into vertical pin holes formed in the end portion of the fixed rail body and the end portion of the movable rail body. The pin hole at least at one end of the movable rail body is formed as a long hole that is long in the length direction of the rail, and the traveling direction of the traveling body and the long diameter direction of the long hole coincide with each other.

According to this, the movable rail body is displaced in the longitudinal direction within the range of the long diameter of the long hole with respect to the fixed rail body by the relative movement of the connecting pin in the long diameter direction of the long hole. This prevents damage to the movable rail body and the fixed rail body when one floor portion is displaced in the horizontal direction with respect to the other floor portion. According to a fifth aspect of the present invention, each power feeding division body is mounted on a mounting member, and each mounting member is mounted on a support member mounted and fixed to the movable rail body, and a length of the movable rail body is provided via a slide member. It is mounted so that it can move in any direction.

According to this, each mounting member moves in the lengthwise direction of the movable rail body through the slide member, so that each power supply division body and the movable rail body are integrated with the respective mounting member. Move in the direction. This prevents damage to the fixed-side power feeding member and the movable-side power feeding member when one floor portion is displaced in the horizontal direction with respect to the other floor portion.

According to the sixth aspect of the present invention, one end of the tension member is connected to one connecting pin provided on one of the attachment members adjacent to each other, and the other end of the tension member is provided on the other attachment member. Is connected to the other connecting pin, a connecting member is provided between the one connecting pin and the other connecting pin, and the connecting member has one connecting hole through which the one connecting pin is inserted and the other connecting pin. And the other connection hole through which at least one of the connection holes is formed as a long hole extending in the length direction of the rail body.

According to this, by the relative movement of the connecting pin in the direction of the long diameter of the connection hole of the long hole, one attachment member has a long diameter of the connection hole of the long hole with respect to the other adjacent attachment member. Displaces in the length direction within the range. This allows
The distance between the one power supply division body and the other power supply division body which are adjacent to each other is increased or decreased within the range of the major axis of the connection hole of the elongated hole. Therefore, the distance between one of the power supply divisions adjacent to each other and the other of the power supply divisions exceeds the allowable range,
Expansion of the long hole beyond the range of the long diameter of the connection hole is restricted.

The action of will be explained. That is, as shown in FIG. 3, one floor 10 is displaced in the front-rear direction A with respect to the other floor 11 (or the other floor 11 is relative to the one floor 10) due to an earthquake or the like. When the space between the floor portions 10 and 11 expands and contracts in the front-rear direction A, the movable rail body 53 is fixed to one of the fixed rails by the relative movement of the connecting pin 62 in the long diameter direction of the elongated hole 57. With respect to the body 51, the pin hole 57 is displaced in the longitudinal direction L (longitudinal direction A) within the range D of the major axis. This prevents the movable rail body 53 and the fixed rail bodies 51, 52 from being damaged.

Similarly, as shown in FIGS. 8 and 9, each power supply division rail body 76 is also integrated with each attachment member 78 in the length direction L (front-back direction A) via the slide rail 80. Moving. As a result, the fixed-side power supply rails 70, 71
Also, the movable power feeding rail 73 is prevented from being damaged. At this time, the space S between adjacent power supply split rail bodies 76 is expanded or contracted. However, since the power supply split rail bodies 76 are evenly pulled by the tension coil springs 82, all the space S is provided. It becomes almost even at the points. As a result, it is possible to prevent nonuniformity of the interval S such that the interval S at some locations becomes extremely larger than the interval S at other locations, exceeding the allowable range. Therefore, when the carrier truck 6 travels, the collector 1
04 can surely pass the space S between the adjacent power-supply split rail bodies 76. Therefore, it is possible to prevent the problem that the above-mentioned interval S becomes too large and the current collector 104 does not come into contact with the power supply split rail body 76 and the power supply to the transport carriage 6 is stopped.

Further, when each power supply division rail body 76 moves in the length direction L as described above, one of the connecting pins 84 is used.
Since a moves relatively in the major axis direction of one of the connecting holes 85a, the one mounting member 78 has a major axis range E of the one connecting hole 85a with respect to the adjacent other mounting member 78.
Displaces in the length direction. As a result, the distance S between the one power-feeding split rail body 76 and the other power-feeding split rail body 76 adjacent to each other is, as shown by the one-dot chain line and two-dot chain line in FIG. It is expanded or contracted within the range E of the major axis. Therefore, it is restricted that the interval S exceeds the allowable range and becomes larger than the range E of the major axis of the one connection hole 85a.

Further, as shown in FIG. 4, one floor portion 10
Is displaced in the left-right direction B with respect to the other floor portion 11 (or the other floor portion 11 with respect to the one floor portion 10), the movable rail body 53 is
It is rotated in the horizontal direction about a vertical axis 64 passing through both connecting pins 62, 63. This prevents the movable rail body 53 and the fixed rail bodies 51, 52 from being damaged.

Also in this case, the spacing S between the adjacent power-supplying split rail bodies 76 is substantially equal at all points.
Nonuniformity of the interval S such that the interval S of some places becomes extremely larger than the interval S of other places beyond the allowable range is prevented. Therefore, the interval S becomes too large and the current collector 104 feeds power. It is possible to prevent the problem that the power supply to the carrier truck 6 is stopped without coming into contact with the for-use split rail body 76.

As described above, even when one floor portion 10 is displaced in the front-rear direction A or the left-right direction B with respect to the other floor portion 11, the movable rail body 53 and the fixed rail bodies 51, 52 are provided.
Since damage to the rails is prevented, the pair of guide rollers 103 roll along both side surfaces of each of the rail bodies 51, 52, 53, whereby the carriage 6 is guided by the guide rollers 103. The vehicle is guided by the bodies 51, 52, and 53 and can travel. Further, it is possible to prevent a problem in which the interval S becomes too large beyond the allowable range and the current collector 104 does not come into contact with the power supply split rail body 76 and the power supply to the transport carriage 6 is stopped. Therefore, even if an earthquake occurs to some extent, it is possible to respond without stopping the system of the entire automated warehouse 1.

In the above embodiment, the carrier 6 travels on the floors 10 and 11 and the floor 16 while being guided by the guide rails 17. Alternatively, it may be a type of traveling on the guide rail 17.

As described above, according to the first aspect of the present invention, when one floor is displaced in the horizontal direction with respect to the other floor,
Each of the power supply divisions moves in the length direction, and the space between adjacent power supply divisions expands or contracts. At this time, the adjacent power supply divisions are pulled by the tension members, and damage to the fixed-side power supply member and the movable-side power supply member is prevented.

According to the second aspect of the present invention, the intervals between the power supply divisions are substantially equal at all locations, so that the spacing at some locations exceeds the tolerance at other locations and is extremely far beyond the allowable range. Non-uniformity in the spacing, such as an increase in size, is prevented. Therefore, when the traveling body travels, the current collector can surely pass through the space between the power feeding division body and the power feeding division body.
As a result, it is possible to prevent a problem in which the above-mentioned interval becomes too large and the current collector does not come into contact with the power feeding division body and the power feeding to the traveling body is stopped.

According to the third aspect of the present invention, when one floor portion is displaced in the horizontal direction with respect to the other floor portion, the movable rail body is displaced in the length direction or horizontally rotated about the vertical axis. Therefore, the movable rail body and the fixed rail body are prevented from being damaged. According to the fourth aspect of the present invention, the movable rail body is displaced in the longitudinal direction within the range of the long diameter of the long hole with respect to the fixed rail body by the relative movement of the connecting pin in the long diameter direction of the long hole. This prevents damage to the movable rail body and the fixed rail body when one floor portion is displaced in the horizontal direction with respect to the other floor portion.

According to the fifth aspect of the present invention, each mounting member moves in the length direction of the movable rail body through the slide member, so that each power supply division body and the movable rail body are integrated with the mounting member. Move along the length of. This prevents damage to the fixed-side power feeding member and the movable-side power feeding member when one floor portion is displaced in the horizontal direction with respect to the other floor portion.

According to the sixth aspect of the present invention, the connecting pin relatively moves in the major axis direction of the connection hole of the elongated hole, so that the one attachment member is connected to the other adjacent attachment member of the elongated hole. Displaces in the longitudinal direction within the range of the major axis of the hole. As a result, the distance between the one power supply division body and the other power supply division body that are adjacent to each other is expanded or reduced within the range of the major axis of the connection hole of the elongated hole. Therefore, it is regulated that the distance between the one power supply division body and the other power supply division body adjacent to each other exceeds the allowable range and becomes larger than the range of the long diameter of the connection hole of the long hole.
