Abstract

PURPOSE:To make intensive storage of multifarious articles and their omnidirectional handling operations performable, by installing a water fillable article housing section, and also installing an article storing floating bottom plate liftably movable according to a water fillup quantity inside the section as well as constituting the floating bottom plate possible to be rotated and driven. CONSTITUTION:When dry chemicals are warehoused in a small bin Y5, by way of example, a water filling quantity 18 inside a section 17 is drained, making a floating bottom plate 23 go down, and a receiving port 12 and a ventilating port 26 of the bin Y5 are opened, while it is tilted at more than an angle of repose in an article and water is poured thereinto. When the bin Y5 delivers these chemicals on the contrary, water is filled up inside the section 17, making the floating bottom plate 23 go up and they are delivered out so as to cause a position of a delivery port 14 to come to be more than the repose angle made by a truck rear body. And, the injection water out of a pump is made to collide with the concave part 9 installed on an outer circumference of the floating bottom plate 23, rotating this plate 23 in the circumferential direction, thus the delivery port is moved to an optional position. With this constitution, intensive storage and omnidirectional loading are made performable.

Description

DETAILED DESCRIPTION OF THE INVENTION When many kinds of articles are stored in a corner of an outdoor site or a corner of a building, the direction of loading and unloading them is limited, so the centralized storage and first-in, first-out loading and unloading of the articles is possible. In order to solve the problem of not being able to do so, we are trying to provide a multi-level warehouse that can centrally store a variety of goods and perform cargo handling in all directions.In general, the direction of logistics innovation from a physical perspective is to minimize the amount of logistics movement. , shortening and straightening the travel distance, consolidating cargo handling and storage at both ends of the travel distance, and minimizing the amount of cargo handling associated with this. The main focus of the present invention is to integrate the handling and storage of articles and to minimize the amount of cargo handling, and is aimed at economical and physical innovation in logistics.

Hereinafter, an embodiment of a wharf warehouse for collecting and managing powder and granular materials will be described in detail with reference to the drawings.

General powder and granular materials include those packaged in bags, bulk containers, polybags, etc., and those for food, feed, fertilizer, etc. such as corn, wheat, beans, and fish meal9, which are transported and stored in a distributed manner. There is. Furthermore, there is a tendency for items to be transported and stored in bulk in order to save on administrative expenses and transportation costs. Therefore, not only large grains, feed fertilizers, but also small grains,
There is an increasing need for storage warehouses for dry chemicals. Currently, these waste materials are stored and spread out in upright cylindrical tanks (called silos). Since the height of these bins is 30 m to 50 m above the ground, the amount of vertical movement of stored materials becomes large, resulting in high cargo handling costs, and since the building is a high-rise building, there are problems in that strong wind countermeasures and foundation construction costs are high.

In addition, due to profitability constraints, it is not possible to install all dedicated cargo handling equipment for each single bin, so a common cargo handling line for multiple bins is arranged. For this reason, even if it were possible to transport dry chemicals in small quantities, the bins would be too large and the shared cargo handling line would not be able to be completely cleaned, and even if it was disassembled and thoroughly cleaned as much as possible, However, there are some gaps that cannot be shared for the loading and unloading of different types of materials. Due to the chemical properties of dry chemicals, contamination with foreign substances is not allowed, so there is no other solution to this problem than setting up a dedicated cargo handling line.

In view of these points, the present invention has a floating bottom plate for storing articles that is configured to be rotatable in order to minimize the amount of loading and unloading of articles and cargo handling, eliminate the chance of foreign matter getting mixed in during cargo handling, and simplify cleaning of cargo handling equipment. At the very least, the aim is to create a three-dimensional warehouse that can carry out cargo handling in virtually all directions, thereby reducing the need for cargo handling equipment and minimizing cargo handling costs.

What is shown in FIG. 1 is an explanatory diagram conceptually illustrating loading and unloading cargo handling jl 59 from a berthed ship to a silo.

1-b is the distance traveled by the cargo handling grab bucket 2 of the gantry crane 1 installed on the ship side to receive the goods 13 from the berthed ship 3 to the hopper equipment 5 on the quay 4, and f (z is the distance traveled by the hopper Bake from 7 to 9 by the seater 9 installed in the underground space.

It shows the height from the position where the bottle is poured to the bottom of the bottle elevator 10 to the horizontal conveyor 11 on the top of the bottle.

In order to minimize the cost of loading and unloading materials, handling (
This is nothing but shortening the horizontal movement distance of Df+D2) and the vertical movement distance of (H+H2). The shorter these distances are, the faster the cargo handling speed will be, the lower the cargo handling costs will be, and the more ancillary cargo handling equipment can be reduced. A horizontal conveyor 11 on the roof of the bin is used to sequentially drop and transfer substances in a multi-stage manner, and the substances are collected and stored in the bin through a receiving opening 12. The materials 13 in the bin are loaded from the bottom discharge port 1, 1 through the entire hopper scale 15 onto the shipping truck 16. On the other hand, in the silo method, the entire load of the upper structure and stored materials must be supported by the lower concrete structure (not shown), so the foundation construction costs tend to be relatively high as piling is carried out until it reaches the bedrock. be.

FIG. 2 is a plan view showing an embodiment of the present invention, and FIG. 3 is an elevational sectional view taken along line A in FIG. An article storage compartment 17 capable of storing water is constructed in a circular shape, and an arbitrary amount of waste water 18 is introduced from a natural water source 19 through a conventional pump 20, a valve 21, and a communication pipe 22, and a circular compartment is constructed inside the compartment. A floating bottom plate 23 for article storage is arranged. In the illustrated example, the storage plate is integrated with a storage space, and the inside thereof is used as an article storage space. Further, although not shown, a vertical conveyor and a lower discharge port may be provided to utilize the void space 25 for cargo handling. In the illustrated example, the article storage compartment 17 is arranged adjacent to the ship berthing quay 1, and Dl shown in FIG. 1 is the minimum. The upper part of the storage plate, which has an integrated structure with the storage space, is divided according to a free design considering all types and quantities of items to be handled. What is shown in the figure is a plurality of small bead Yl,' on the upper peripheral part of the holding plate.
All examples of aggregation of bins of various scorches are shown, where Y2...Y6 are divided into sections of appropriate size, and a large bin X for main storage materials is sectioned in the center. As a result, dry chemicals and the like that require completely separate storage and dedicated cargo handling equipment can be stored in the small bottles Yl, Y2, . . . Y6. Loading and handling of the large bin X can also be simplified. That is, for example, small bottle Y
When storing dry chemicals in the tank 5, drain the natural water volume 18 in the compartment 17, lower the storage plate 23, and open the Y5 bin intake 12 and ventilation port 26 in the same way as the shooter 9 in Figure 1. This allows loading and unloading by creating an incline that exceeds the angle of repose of the material. When exiting from bin Y5, section 17
The water is introduced into the interior and the holding plate 23 is raised. After the angle between the position of the delivery port 14 shown in FIG. 5 and the shipping truck bed exceeds the angle of repose of the material, the delivery port is opened and cargo is handled in a similar chute. do it. This simplifies the cleaning of the cargo handling equipment and eliminates the need for common parts of the cargo handling line, reducing the chances of foreign matter getting mixed in. At the bottom of the X and Y valley pins, a suitable bottom plate slope 24 is provided so that the goods can be shipped in sequence, and in the lower void space 25 there are suitable supporting materials such as pillars, entrances and exits for inspection of the water structure (not shown), etc. will be established. A vertical cylindrical strong support may be provided at the center line of the X-bin, and the inside thereof may be used as an inspection port that can be raised and lowered.

The design takes into account the reserve buoyancy of the bullet bottom plate, and as with the current shipping method of silos, the top surface of the bullet bottom plate will be used as a cargo handling floor to match the ground height, and both sides of the same thick bottom plate will be open. It is also possible to introduce a shipping truck onto the holding plate as a path for the molds. Comparing this with the cargo handling mode of the current silo, it can be seen that the vertical cargo handling distance of 112 distances is shortened and replaced with water level adjustment in section 17. The small Y bin is installed above the periphery of the bullet bottom plate so that it can be loaded and unloaded using only a natural ute by adjusting the water level. 1. As shown in Figures 1 and 6, the large bin Since it can be installed below the Y-bin or partially through the Y-bin so that it can be opened and closed at its outer periphery, it can be loaded and unloaded in the same way as the Y-bin. It can also be used as a storage space for an lx bin below the bottom of the Y pin. If first-in, first-out of various materials is strictly required, the bin section can be further divided vertically or horizontally (not shown). In short, if the receiving and discharging ports of each bin are located on the outer periphery, loading and unloading can be carried out.

Each bottle has a ventilation port 26, and illustrations of a temperature measurement port, fumigation solution, etc. are omitted.

Since the stored materials in each bin are loaded and unloaded according to a natural notebook, the bottom plate 23 is rotated so that the receiving and discharging port 14 is close to the horizontal holding truck, which simplifies loading and unloading of stored materials. can be converted into

Next, the rotatable configuration of the bullet bottom plate 23 will be explained.

In the illustrated example, the guide mechanism 27 for raising and lowering the bullet bottom plate 23 uses a ball bearing type that can freely move.

Although not shown, it is also possible to provide a vertically penetrating guide post at an appropriate position of the bullet bottom plate 23 so that the outer peripheral surface of the bullet bottom plate and the storage compartment 17 do not come into contact with each other during the vertical movement thereof. 7th. The one shown in FIG. 8 is one in which an appropriate number of propulsion devices 30 are installed at the bottom of the periphery of a retaining plate 230 to provide propulsion force in all horizontal directions, and are capable of transmitting conventional assistance by ground operation. Other methods may also be used, such as applying the discharge water pressure continuously to resistance vanes provided at regular intervals on the side surface of the bomb bottom plate to apply rotational force to the nuclear floating bottom plate.

The force required to rotate the bullet bottom plate 23 is caused by the frictional force between the bottom plate 23 and the seed water 18 in the article storage compartment, and the rotation direction toward the vertical guide caused by the uneven load applied to the storage plate depending on the storage condition of the stored items 13. ) The vertical guide 27 is connected to the bottom plate 23
The restoring force of the bullet bottom plate can be ignored because it is installed so that it does not tilt when the bullet is raised or lowered. It has been proven through experiments that the frictional resistance force is proportional to the submerged surface area of the bullet bottom plate, and approximately proportional to the square of the rotational movement speed, so the force required to slowly rotate the floating bottom plate is extremely small. It's fine. Therefore, as shown in the example, if the various bottles are arranged at target positions so that a large unbalanced load does not act on the bullet bottom plate 23, the rotational movement of the bullet bottom plate becomes easier. It is also possible to arrange an appropriate number of tanks at symmetrical positions on the periphery so that the unbalanced load does not act too much. With this configuration, for example, Y
If you want to carry out loading and unloading of 2 bins all on the quay side, use Y2.
All you have to do is drive the propulsion device to move and rotate the bullet bottom plate so that the pin is at the position of the Y5 bin. Similarly, when shipping on the inland side opposite to the quay, the Y-pins of the required sections can be rotated completely inland and then unloaded, allowing cargo handling in all directions.

The effects of the present invention are as follows. 1. Since the horizontal and vertical cargo handling distances (D+H) shown in FIG. 1 are shortened, the cargo handling speed is increased and cargo handling costs are reduced. 2. Since the required cargo handling equipment is reduced, preparation for storage of different types of items is simplified, and cleaning costs can be saved by a considerable amount. 3. Since the bullet bottom plate for article storage is configured to be rotatable, loading and unloading can be carried out at any desired position. Practically all-directional cargo handling becomes OJ capability. ,
1.Even in the case of a location where loading and unloading can only be carried out at one location, cargo handling can be carried out in all directions, so goods storage can be consolidated. In other words, it is possible to carry out first-in, first-out operations for items stored out of sight from the storage/retrieval position.
