Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a storage control method for stored items for evenly distributing stored items in a warehouse in which seismic isolation devices are installed.
[0002]
[Prior art]
For seismic isolation structures that dampen vibrations that are transmitted from the ground or lower structure to the structure due to earthquakes, etc. by installing seismic isolation devices on the foundation or intermediate floor pillars, etc. In order to effectively exhibit the seismic effect, it is desirable that the period, amplitude, direction, acceleration, etc. of the force acting on the seismic isolation device from the superstructure during the earthquake are the same and small over the entire plane of the structure. .
And in order to adapt to such a request | requirement, it is important to equalize the load per floor area of the lowest part in the upper structure in which the seismic isolation apparatus was interposed.
[0003]
By the way, when the above seismic isolation structure is a general high-rise office building or apartment house, the building itself is designed so that the load per floor area at the bottom is almost equal, and the interior Since the weight of the article or person is much smaller than the weight of the building, the seismic isolation device can function effectively.
[0004]
[Problems to be solved by the invention]
However, when the above seismic isolation structure is a structure that stores a heavy load (load) in a plurality of compartments defined like an automatic warehouse, the weight of the warehouse is relatively low. Although it is small, the weight of the stored item may be ten times or more. Moreover, in the conventional automatic warehouse of this type, the storage location of the stored items is generally determined in a random manner using random numbers, etc. As a result, there is a problem that it is difficult to effectively exhibit the seismic isolation effect by the seismic isolation device.
[0005]
In addition, particularly when the automatic warehouse is high-rise, this tendency becomes remarkable, and in addition to the uneven distribution of the storage in the planar section, the uneven distribution of the storage in the height direction also increases. There is a problem that it becomes difficult to keep the position of the center of gravity as low as possible.
[0006]
The present invention has been made in view of the above circumstances, and it is possible to disperse the stored items so that the load per floor area in the floor where the seismic isolation device is interposed is made as uniform as possible. It is an object of the present invention to provide a storage control method for stored items in a seismic isolation warehouse that can effectively function the seismic isolation device.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a storage control method for stored items in the seismic isolation device, wherein the seismic isolation device is interposed between the upper and lower structures, and the upper structure has a plurality of sections for storing the stored items in a plane. A storage control method for the above-mentioned stored items in a seismically isolated warehouse, which is defined in a grid shape and is provided in a plurality of stages in the vertical direction, and is provided with a transport means for transferring the stored items to and from the compartment. Know the weight, calculate the vertical cumulative load of the containment per compartment, and store the containment so that the vertical cumulative load in each compartment is more even when adding or subtracting the weight of the containment The section to be stored or the section from which the stored item is delivered is determined, and the stored item is carried into or out of the section by the conveying means.
[0008]
The invention according to claim 2 is the invention according to claim 1, wherein the stored item is carried into the lowermost compartment of the compartment or carried out of the uppermost compartment. It is a feature.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment in which a storage / exit control method for stored items in a base-isolated warehouse according to the present invention is applied to a base-isolated automatic warehouse based on the drawings.
First, the configuration of the seismic isolation automatic warehouse will be described. As shown in FIGS. 1 and 2, the automatic warehouse (upper structure) 1 has a base (lower structure) 2 and a seismic isolation device 3 interposed therebetween. As a result, seismic isolation is achieved, and a plurality of rows (four rows in the figure) of shelves 4 are stored in a plurality of grid-like sections 5 on each plane. Are provided in a plurality of stages in the vertical direction.
[0010]
And between the pair of shelves, a stacker crane (conveying means) 6 for loading and unloading the stored items 4 into and from each section 5 is provided movably. Further, a control means having a computer 7 for controlling the operation of the stacker crane 6 and a storage device 8 in which a weight management file 9 of the stored items 4 connected thereto is written.
[0011]
Next, the storage / exit control method for the stored item 4 in the seismic isolation automatic warehouse 1 having the above-described configuration will be described with reference to FIGS.
First, when the stored item 4a is carried in, the weight of the stored item 4a is grasped by direct measurement using a weighing machine or measurement using a product name and load data table, and the weight data is input to the computer 7.
[0012]
On the other hand, a weight management file 9 as shown in FIG. 3 is stored in the storage device 8 connected to the computer 7 in advance. This weight management file 9 is a table in which the column is provided with the address of the shelf compartment 5 in each plane, and the row is provided with the number of steps of the shelf and the height dimension, and the stored contents 4 stored in each compartment 5 are stored. Presence / absence and its weight data are input, and the cumulative weight (vertical cumulative load) ΣW (Ton) in the height direction per plane address calculated by the computer 7 based on these weight data, and the height of the center of gravity (HGmh) is input. Here, the height of the center of gravity is (W ₁ × H1 + W ₂ × H2 +... + WM × HM) / ΣW
Is calculated by
[0013]
Therefore, when the weight of the storage 4a is added from the weight management file 9 and the newly input storage 4a by the computer 7, the vertical cumulative load ΣW in the mutual compartment 5, that is, the automatic warehouse A comparison operation is performed so that the vertical cumulative loads on the floor of the lowest floor of 1 are equal, and the address of the section 5 in which the stored item 4a is received is retrieved. At this time, if there is a vacancy in a plurality of levels in the height direction in the retrieved section 5, it is determined to be carried into the lowermost section 5 of them.
[0014]
And based on this result, the said storage 4a is carried in to the determined division 5 by carrying out operation control of the stacker crane 6. FIG. Further, for the weight management file 9 in the storage device 8, data of the newly loaded storage 4a is added, and the height direction per plane address similarly calculated by the computer 7 based on this is added. The cumulative weight ΣW (Ton) and the center of gravity height (HGmh) are input.
[0015]
Further, when the stored item 4 stored in the automatic warehouse 1 is carried out, when the weight of the stored item 4 in a certain section 5 is subtracted by referring to the weight management file 9 in the computer 7, The compartment 5 where the stored item 4 is delivered is searched so that the vertical cumulative load ΣW in the mutual compartment 5 becomes more uniform. Also in this case, when the stored items 4 are stored in a plurality of stages in the height direction in the retrieved section 5, it is determined to carry out the stored items 4 in the uppermost section 5 among them. And based on this result, by controlling the operation of the stacker crane 6, the stored item 4 in the section 5 is carried out.
[0016]
By the way, at the time of delivery, for example, when the stored item 4 to be carried out has no selectivity and the specific stored item 4 is carried out, the above-described vertical cumulative load becomes uneven. Therefore, in such a case, the computer 7 refers to the weight management file 9 by using the outside of the work time period or the like so that the vertical cumulative load ΣW becomes uniform and the center of gravity height is further increased. Arithmetic processing is performed so as to be further lowered, and the stacker crane 6 is operation-controlled to rearrange the stored items 4.
[0017]
Thus, according to the storage / exit control method for the stored item 4 in the seismic isolation automatic warehouse 1, when storing, the weight of the stored item 4 a is grasped and the vertical cumulative load ΣW of the stored item 4 per section 5 is obtained. When the weight of the storage 4a is calculated and the vertical accumulated load ΣW in each of the partitions 5 is more equal, the storage 5 is searched and the storage 4a is stored by the stacker crane 6. At the time of delivery to the compartment 5 and at the time of delivery, the compartment in which the containment 4 is delivered is searched so that the vertical cumulative load ΣW in the compartment 5 becomes more equal when the weight of the containment 4 is subtracted. In addition, since the stacker crane 6 carries out the section 5, the storage 4 can be dispersed so that the load per floor area in the layer where the seismic isolation device 3 is interposed is made as uniform as possible.
[0018]
In addition, at the time of warehousing, the stored matter 4a is carried into the lowest compartment 5 among the searched compartments 5, and at the time of delivery, the stored matter 4 is stored in the searched compartment 5 Since it is carried out from the uppermost section 5 among them, the position of the center of gravity can be suppressed as low as possible.
As a result, according to the storage / exit control method for the stored items 4 in the automatic seismic isolation warehouse 1, the seismic isolation device 3 can always function effectively.
[0019]
【The invention's effect】
As described above, according to the first or second aspect of the present invention, when storing or unloading the stored item, the load per floor area in the floor where the seismic isolation device is interposed is made as uniform as possible. Therefore, the seismic isolation device can function effectively at all times.
[0020]
At this time, in particular, according to the invention described in claim 2, since the stored item is carried into the lowermost compartment among the compartments or carried out from the uppermost compartment, The effect that it can be suppressed as low as possible is obtained.
