0002

2. Description of the Related Art An example of the configuration of a conventional cargo handling facility equipped with the above-mentioned conveyor facility will be explained based on the layout diagram of FIG.

The cargo handling equipment shown in FIG. 3 includes a shelf 3 having a plurality of cargo storage spaces 2 for storing cargo 1, a self-propelled vehicle along a fixed path 4 along the shelf 3, and a cargo handling equipment that moves the cargo 1 between the shelf 3 and the shelf 3. A crane 5 that performs loading/unloading, and two loading/unloading conveyors 6 that transport cargo 1 between the loading/unloading position of crane 5 and the loading/unloading position of cargo 1.
6 sets of automated warehouses 8 equipped with warehousing and unloading conveyors 6, and 6 self-propelled conveyance carts 10 that load and unload goods 1 and run on endless rails 9 to transport goods 1. and loading and unloading the load 1 with the self-propelled carrier 10,
It is composed of eight carry-in/out conveyors 11 for carrying out. In FIG. 3, the numbers in the frame indicating the conveyor indicate the conveyor number, N0.1 to N0.12 indicate the loading/unloading conveyor 6, and N0.13 to N0.20 indicate the loading/unloading conveyor 11.

[0004] These conveyors 6 and 11 are arranged as shown in the cable layout diagram of the conveyor equipment in FIG.
Every three units are connected by cable to a power distribution board 12 outside the facility, and are supplied with power. For example, No. 1 loading/unloading conveyor 6
is connected to a power distribution board 12 outside the facility by a cable 13, and a cable 14 is connected from this N0.1 loading/unloading conveyor 6 to the N0.2 and N0.3 loading/unloading conveyors 6 to supply power.

[0005] The crane 5 of the automated warehouse 8 is supplied with power from a power supply rail laid along a fixed route 4 and connected to a power distribution board 12 by a cable via a current collector (none of which is shown in the figure). The traveling carriage 10 is laid along rails 9, and is supplied with power from a power supply rail connected to a power distribution board 12 by a cable via a current collector (none of which is shown).

[0006]

[Problems to be Solved by the Invention] However, according to the above-mentioned conventional example, cable laying work is difficult because there are a large number of cables 13 that feed power from the power distribution board 12 outside the equipment to each conveyor 6, 11 of the conveyor equipment. There is a problem that it takes time to install the cable, and since the cable 13 is installed from the switchboard 12 outside the facility, the length of the cable 13 becomes long, and the total length of the cable becomes long, which increases the cost. Furthermore, since the length of the cable 13 varies depending on the location of the switchboard 12 and the shape of the building, it cannot be determined until the conveyors 6 and 11 are installed in the building. Therefore, the cable must be manufactured on-site, which reduces the cable manufacturing time. This posed the problem of increasing on-site electrical work time for power supply and increasing costs.

[0007] The present invention solves the above problems, and
The purpose of the present invention is to provide conveyor equipment that can shorten on-site electrical work time and shorten the total length of cables.

[0008]

[Means for Solving the Problems] In order to solve the above problems, the conveyor equipment of the present invention provides a terminal box for receiving power for each of a plurality of conveyors forming a block, and supplies power from each terminal box to the conveyors in the block. It is characterized by:

[0009]

[Effect] According to the above configuration, the number of cables laid between the power distribution board outside the facility and the terminal box is reduced, and the length of the cables feeding power from the terminal box to each conveyor depends on the location of the power distribution board and the shape of the building. Therefore, it becomes possible to manufacture the cables between the terminal box and each conveyor and send them to the site, thereby shortening the electrical work time on site. Furthermore, it is possible to shorten the total length of the cable.

, 22 and led through a main duct 23 and a subduct 24, power is supplied to each conveyor 6, 11. That is, the cable 27 passes through the main duct 36 and the subduct 37 and passes from the first terminal box 21 to each of the four loading/unloading conveyors 6.
A cable 28 is laid from the second terminal box 22 to each of the four loading/unloading conveyors 11.

[0014] With the above configuration, the terminal boxes 21, 2 in the equipment
2 to each conveyor 6, 11 is connected to the switchboard 12.
The cable 27,
The length of 28 is specified, the cable is manufactured in advance in the factory, that is, it is cut according to the cable length, and terminals that match the terminal blocks of the terminal boxes 21 and 22 are glued to both ends of the cable. Can be carried into the building. Therefore, the cables within the facility only need to be laid on site, and then
The electrical work can be completed by measuring the wiring route between the power distribution board 12 outside the facility and the terminal boxes 21, 22, manufacturing the cables 25, 26, and laying them.

In this way, by forming blocks for each conveyor location or use, and providing each block with terminal boxes 21 and 22 that receive power from the power distribution board 12 outside the facility, on-site electrical work can be reduced and further Compared to the example, it is possible to reduce the number of long cables laid from the power distribution board 12 outside the facility to the inside of the facility (terminal boxes 21, 22), thereby shortening the on-site construction time. Standardization can be promoted and costs can be reduced. Furthermore, the total length of the cables 25, 26, 27, and 28 can be shortened compared to the conventional example, and costs can be reduced.

Note that in this embodiment, the terminal boxes 21, 2
2 may not only simply branch the cables, but may also insert a breaker for each branched cable so that each power supply can be turned on and off. In addition, in this embodiment, the cables 27 and 28 for the conveyors 6 and 11 are connected to the main duct 23 and the subduct 24 in the rail 9 for the self-propelled carrier 10.
Although the wiring route is routed through the inside of the equipment, it is also possible to run a route that allows the wiring route within the equipment to be specified.

[0017]

[Effects of the Invention] According to the above configuration of the present invention, the number of cables laid between the power distribution board and the terminal box outside the equipment can be reduced.
Additionally, the length of the cable that supplies power from the terminal box to each conveyor is determined regardless of the location of the switchboard or the shape of the building, making it possible to manufacture cables between the terminal box and each conveyor and send them to the site. Therefore, it is possible to shorten the time required for electrical work on-site, and furthermore, it is possible to shorten the total length of cables, thereby reducing costs.
