Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a loading platform adjacent to the end of the travel path of a traveling crane for loading and unloading, for transferring loads to and from the crane; This invention relates to a cargo handling area structure for an automated warehouse in which a safety fence is erected to surround the end of a crane travel path.

(Prior art and its problems) At the end of the traveling route of a traveling crane for loading and unloading, a loading platform (a mobile loading deck using a trolley or a fixed loading deck) is installed to transfer cargo to and from the crane. A cargo handling area of an automated warehouse requires an operation panel for carrying out loading and unloading operations using the cargo receiving platform. In other words, in the case of a mobile receiving platform using a trolley, settings such as continuous warehousing, continuous unloading, or random loading/unloading, and completion operations for setting pallets on the receiving platform or discharging pallets from the receiving platform, etc. are performed.
In the case of a fixed loading platform, an operation panel is required to complete the pallet setting or pallet discharging operation.

Conventionally, the operation panel was supported by a post erected independently at an appropriate position on the floor of the cargo handling area, and the wiring for the operation panel was laid on the floor using a wiring duct. With such a conventional configuration, not only is the installation cost of the operation panel high, but there is also a high possibility that a cargo handling vehicle such as a forklift traveling nearby may come into contact with the operation panel and cause damage.

(Means for Solving the Problems) The present invention proposes a cargo handling area structure for an automated warehouse that can solve the conventional problems as described above. The loading platform is used in an automated warehouse in which a loading platform is provided adjacent to the end of the route for transferring loads to and from the crane, and a safety fence is erected to surround the end of the crane traveling route. An operation panel for advancing the loading/unloading operation is provided at the safety fence position, and wiring for the operation panel is arranged within the base frame of the safety fence.

(Embodiment) An embodiment of the present invention will be described below based on the attached illustrative drawings. In FIG. 1, 1 indicates fences 2 and 3.
It is a traveling crane for loading and unloading that travels on a traveling route 4 between the warehouses and has an elevating carriage 6 equipped with running forks 5 for receiving and receiving loads that move in and out from left to right as is conventionally known. Reference numeral 7 denotes a movable loading platform using a trolley, which is installed at one end of the crane travel path 4, that is, on one side of the left and right sides of the home position of the crane 1, and 8 is the other side of the left and right side of the home position of the crane 1. This is a fixed loading platform installed at The movable loading platform 7 reciprocates between a crane side position A where loads are transferred to and from the crane 1 and a loading handling side position B on a guide rail 9 laid parallel to the moving path of the crane 1. It is something to do. Reference numeral 10 denotes a safety fence that surrounds the home position side end of the crane travel path 4, and as shown in FIG. A pair of left and right guard frames 12a, 12 fixed to
b, fixed to the worker entrance side end of both guard frames 12a, 12b, and base frame 11;
casings 14a, 14b supported via support members 13a, 13b, and both casings 14
A chain 15 detachably stretched between a and 14b
It consists of In addition, the casing 14
It is also possible to directly fix the lower ends of the support members 13a and 14b onto the base frame 11, thereby omitting the support members 13a and 13b.

Both casings 14a in the safety fence 10,
A movable loading platform operation panel 16 and a fixed loading platform operation panel 17 are fixed to the upper end of the casing 14b, and a movable loading platform operation panel 16 connected to the moving loading platform operation panel 16 is fixed to the casing 14a to which the moving loading platform operating panel 16 is fixed. A loading platform control panel 18 is built-in. As shown in FIG.
A detector for interlock between the
(load detector, interlock detector with the crane 1, etc.) and its control panel 21 are mounted.

Movable loading platform control panel 1 inside the casing 14a
8 is supplied from the distribution board 22 to the power supply line 23,
Power is supplied to the control panel 21 of the fixed load receiving platform 8 from the power supply line 23 to the relay terminal box 24 via a relay terminal box 24 and wiring 25 installed at the end of the moving path of the mobile receiving platform 7. , and wiring 26. As shown in FIGS. 2 and 3, the wiring 25 is inserted through a part of the base frame 11 of the safety fence 10 and the inside of the support member 13a, and the wiring 26 is inserted into the base frame 11 of the safety fence 10. It is inserted through the inner front length. Furthermore, the movable cargo receiving platform control panel 18, various detection devices 19 on the movable receiving platform 7, and traveling motor (not shown) are connected to the relay terminal 2 fixed to the movable receiving platform 7.
7 and the relay terminal box 24 are connected by a wiring 29 supported by a cable guide 28, and the control panel 21 of the fixed loading platform 8 and the safety fence 10
The fixed load receiving platform operation panel 17 fixed to the above means a part of the base frame 11 of the safety fence 10, the inside of the support member 13b, and the casing 14b.
It is connected by a wiring 30 inserted therein.

The mobile receiving platform operation panel 16 is provided with switches and indicator lights for setting cycles such as continuous warehousing, continuous unloading, or random loading/unloading, and completing operations for setting pallets on the receiving platform or discharging pallets from the receiving platform. The fixed loading platform operation panel 17 includes:
A switch, an indicator light, etc. are provided for completing the pallet setting or pallet dispensing operation.

(Operations and Effects of the Invention) According to the automatic warehouse material handling area structure of the present invention that can be implemented as described above, the receiving platform (in the embodiment, both a moving receiving platform and a fixed receiving platform, but only one of the receiving platforms) can be used. An operation panel for proceeding with the loading/unloading operation using a crane (which may be installed) was installed at the safety fence position surrounding the end of the crane travel path, and the wiring for this operation panel was placed within the base frame of the safety fence. The operation panel can be fixed to the safety fence to increase the support strength, and a part of the safety fence can also serve as the operation panel support member, thereby reducing the installation cost of the operation panel. Furthermore, the area around the cargo handling area (around the safety fence) can be widened, allowing cargo handling vehicles to travel safely, and accidents involving contact between cargo handling vehicles and operation panels can be reduced.

Furthermore, since there is no need to lay wiring on the floor using a dedicated duct, wiring costs can be reduced, and there is no fear that the wiring duct will interfere with the movement of cargo handling vehicles or the walking of workers.
