Abstract

PURPOSE:To improve controlling looseness of packing for goods and quickly recover from the looseness by providing, in a special place of the row of rack, a detector of said looseness in a goods receiving space and inputting a signal of detection to a control center. CONSTITUTION:An acceleration measuring device 16 is provided in a special place of each row 1-4 of a rack. A signal of measurement from this acceleration measuring device 16 is inputted to a control center 18 for looseness of packing for goods. In a computer 21 of said center 18, comparison is made between a value of acceleration for occurence of looseness of packing and a value of measured acceleration in each housing space for the goods and, when the measured value is large, signals are intputted to a recorder 22. The recorder 22 records and indicates these signals separately by row of the rack and also by block. Thus, a condition of looseness of packing can be grasped, and recovery from the fooseness can be quickened, and precision can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides storage space for the 4NJ storage space by means of a row of ranks defining cargo storage spaces vertically and horizontally, and a transport platform that moves up and down and moves laterally by traveling along the row of ranks. Improving warehouses that have transport equipment to bring cargo into or take cargo out of cargo storage space, specifically, to manage the situation in each predetermined area to prevent damage caused by earthquakes, etc. It relates to improvements devised to ensure accurate management of collapse situations and rapid repair of frontal defects.

The above-mentioned automatic warehouse is known, for example, from Japanese Patent Laid-Open Publication No. 58-42505, and most of the M stored in such an automatic warehouse are generally packed in cardboard boxes. When the cargo packed in cardboard boxes is stored in the cargo storage space, a plurality of the cargoes are stacked on the valet. Therefore, the load stored in the load storage space is likely to be tilted forward due to an earthquake or the like.

Conventionally, when front deviation occurs, the front deviation is detected by the front deviation detector of the transfer equipment (stacker crane) during handling. Stopping the handling of the transport equipment as described above means that the automatic warehouse function is disabled. Therefore, it is necessary to quickly improve the function, but in the conventional case, it is difficult to grasp the overall front drift situation in the warehouse, so it is necessary to check the condition of the cargo in all cargo storage spaces one by one. Not only is the work required to do so difficult, but it also takes a long time to restore functionality.

Therefore, the present invention provides an automatic warehouse capable of dealing with the above-mentioned problems.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, numerals 1 to 4 are rack rows that define 5.5 inches of cargo storage space in the vertical and horizontal directions, and 6 to 8 are rack rows 1 to 4 of the rank rows 1 to 4.
The cargo storage space 5 is moved by a transport platform 12 that moves up and down and laterally while traveling along the rank rows 1 to 4 in the passages 9 to 11 between them.
This is a transport facility (stanker crane) that transports ri 13 into cargo storage spaces 5 and 5, or takes out ri 13 from cargo storage spaces 5 and 5. The transport facilities 6 to 8 are operated by instructions from a control center (not shown). Also, each rank column 1
The cargo storage space 5,5° defined in ~4 is partitioned by a central place 14, and has one cargo opening 15.

is installed. In the illustrated case, assuming that the same type of load 13 is stored in the total load storage space of 5.5'' in each rack row 1 to 4, a plurality of acceleration measuring devices 16 are installed at equal intervals in the length direction and height direction. is installed.Acceleration measurement device 1
6 is the place 14 portion (or other rank component)
It is fixed at °C. - If the type of cargo 13 handled (stored) in one rack row differs from area to area (size of cardboard box, weight of contents, etc.), install the acceleration measuring device 16 according to the form of the area. The location and number of installations will change. In the illustrated case as well, suitable blocks 17 (shown by hatching in FIG. 4) are constructed in the length direction and height direction, and the acceleration measuring device 16 is disposed at the medium heat point of each block 17. Therefore, each rank column 1~
4 is the acceleration measurement value W1 of each block 17.
6 is measured every block 17.

Each of the acceleration measuring devices 16 installed in the rack rows 1 to 4 is connected to a front deviation management facility 18 installed in a control center or the like as shown in FIG.

The front slip management equipment 18 includes an RP multiplier 19. A/D converter 2

The acceleration value corresponding to the load 13 stored in the load storage space 5.5゜ of each block 17 of 4 to 4 causing frontal displacement is input as data. The acceleration value was determined through a vibration experiment and varies depending on the type of load 13 and the height position of block 17. Therefore, in the computer 21, the input signal is compared with the data value, and if it is larger than the data value, it is output, and the output signal is input to the recording device 22.

It is easier to judge the situation 11j1 by illustrating the installation points of No. 6 and displaying them with warning lamps or the like. In addition, the power line display panel is 11. integrated into the I-le panel.

With the above configuration, the vibration at 17 parts of each block in rank columns 1 to 4 is measured by the acceleration measuring device 1G at 1L, and the vibration is measured by the computer 21.
Be man-powered. Then, the computer 21 acts on each block 17, and how many parts of the load 13 stored in the load storage space 5,5° in each block 17 is affected by this vibration?
A determination is made as to whether or not the result is U, and the recording device 22 records and displays the result. Therefore, when an earthquake occurs, the administrator records the record displayed on the recording device W22 as i, :c.

At the same time, dangerous areas within the warehouse can be identified, ensuring safety when entering.

In the above embodiment, the acceleration measuring device 16 is used as a device for detecting the state of collapse of the cargo storage space 61, but a sensor configured by a light projector 4 and a light receiver may be used. In addition, in the case of the example, normally one output No. 14 from the cosiputer 21 is installed (controller 2 of M# 6 to 8).
3 to stop the conveyance equipment U11°16-8.

In summary, the automated warehouse according to the present invention has a row of racks defining a cargo storage space on the side, and a row of racks that moves up and down and moves horizontally along this row of ranks. In an automated warehouse equipped with transport equipment for loading cargo into the cargo storage space or unloading one cargo from one cargo storage space, the cargo storage space is placed at a specific location in the cargo row. In addition to installing a device to detect the state of collapse of cargo, the detection signal from the device is sent manually to the cargo collapse management equipment. The collapse situation is positive 6 (f and can be easily grasped JII+.

Therefore, it is possible to quickly repair the anterior portion, thereby significantly reducing the labor and time required for conventional repair.
