Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Industrial Application Field] The present invention relates to a device for transporting loads from station to station in a building such as a factory or warehouse, and more specifically, to Concerning a conveyance device that travels on a track installed on a road and suspends and conveys a load.

[Conventional technology]

Since the above-mentioned conveyance device suspends and conveys the load, it is provided with safety measures in case the load falls while the vehicle is running. Conventionally, as a means for ensuring safety, a safety net or the like installed below the track of the transport device has been widely used.

[Problem that the invention seeks to solve]

The above-mentioned conventional safety measures require a great deal of labor for installation work, and may vary depending on the factory building in which the transport device is installed and the arrangement of equipment within the building. Therefore, a safety net suitable for the factory must be installed, or even when the track is changed, a great deal of labor is required for the construction work to change the safety net.

, [Means for Solving the Problems] The present invention provides a method for installing a rail of the ceiling self-propelled vehicle (a horizontal line member disposed along the It consists of a support member that connects the H1i1 member to a rail support member Cζ.

[Effect]

By connecting the horizontal line member for receiving and stopping a load that may fall to the rail support member by the support member, the safety member can be installed as part of the conveyance device in the same way as the rail.

〔Example〕

1 to 3 are diagrams showing an example of a conveyance device applied to the present invention, and an outline of this conveyance device will first be explained based on these figures.

The above-mentioned transport device can be roughly divided into a rail (R,) installed near the ceiling, and a ceiling self-propelled vehicle (R,) that runs along the ceiling.
100), and a box-shaped station member (200) installed at a position where the load (B) is carried in or carried out by this conveyance device. The rails (R) are supported by hangers (H), which are rail support members suspended from the ceiling at predetermined intervals, and are arranged along the travel route of the ceiling self-propelled vehicle (100). .

The ceiling self-propelled vehicle (100) includes a driving traveling body (300) and a driven traveling body (400) that travel within the rail (R).
The lower part of the two traveling bodies (300 and 400) is connected to and suspended from the vehicle body part (500), and the vehicle body part (5
00) and a lifting platform (600) that is raised and lowered via belts (519) to (522) by the lifting function within the vehicle body (500). In addition, CB
) indicates a packet which is an object to be transported.

The driving traveling body (300) includes a driving motor (302).
A drive wheel (304X305) and a gear (3068307) which are rotationally driven by the driven traveling body (4
00) Director means that three driven wheels (403) and (404) are each rotatably installed, and a current collector (42B) fixed on the driven ia1 running body (400) is mounted on the inner upper surface of the rail (R). The electric power is supplied by contacting the installed power supply trolley wire (431), and the electric power drives the drive motor (302) and the self-propelled vehicle (100) runs.

The self-propelled vehicle (100) that has traveled to the desired station member (200) position stops at the position, and the vehicle body (500)
) of the drive motor (501) (the belt (5)
By winding and unwinding steps 19) to (522), the lifting platform (600) installed at the lower end of the belt is lowered or raised while being guided by the station member (200).

Below the lifting platform (600), there is a chuck (
612) is installed, and the chuck (612) grips the packet (B).

Next, the structure of the safety fence (1) will be explained. Along the rail (R), there are several horizontal lines (2 in the figure) below the packet (B) being transported by the self-propelled vehicle (100).
(3), and several (two in the figure) side fence lines (4) and (5) are similarly arranged on both sides of the packet (B). The lower horizontal line (2) (3) and the side fence line (4)
(5) is broken at a certain position of the station member (200).

Each horizontal line (21 (3) (4) (5) above is indicated by each hanger (
Directly below the position I-1), it is connected to a connecting line (6), and the connecting line (6) is a supporting line (7) (8) whose one end is fixed to the hanger (1-1). The other end (this is joined. Note that each return line (21 (31 (4) < 5),
For the connection wire (6) and support wires (7) and (8), various materials such as piano wire and pipe material can be used, but the material and diameter are determined by the weight of the items in the packet (B). be done.

Attachment of the support wire (7) to the hanger (H) is carried out on the fourth
Base (9) welded to hanger (H) as shown
and a connecting plate (10) fixed to the end of the support wire (7) are screwed together with bolts (11) and (12).

The attachment of the other support line (8) also has the same structure and will not be described here.

With the safety fence configured as above, packet (B)
We are prepared for the unlikely event of a fall. Installation of the safety fence (1) is easy, just use the bolts (11x12) mentioned above.
If this is done and the distance between the hangers (I-1) is kept constant, the station (200) can be easily installed at any location by considering only the location. The lower horizontal lines (2) and (8) are directly below the packet (B) (approximately 5o
HR), so when the packet (B) falls, the impact given to the bottom (lines (2) and (3)) is small, increasing safety, and each member is made thinner without compromising safety. Therefore, it does not spoil the aesthetic appearance.

In addition, compared to conventional safety measures, the safety fence (1) of this embodiment reduces the amount of land occupied within the factory to a dog's width, making it possible to use the factory interior more effectively. It has an excellent image and is aesthetically pleasing.

Furthermore, since this safety fence (1) is directly supported from the nozzle (H) of the rail (R), it can be applied to various factories according to the same standard. It can be installed without considering the arrangement of equipment within the building. You can also use a hanger (
I-1) If the above safety fence (1) is made into a unit for each length,
Installation is greatly simplified. In addition, the above support line (
7) (8) may be directly fixed to the rail (It). Furthermore, the above matters are also included in the present invention.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to install a safety fence for falling loads with very simple installation work, and it is possible to install a safety fence for falling loads, and to arrange the equipment in a building such as a factory or the like. The above safety fence could be installed without relying on
