Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transportation management method and apparatus for stackable regular articles (self-supporting articles).

[Conventional technology]

The loading/unloading, storage, and preservation of industrial products is one of the important items in transportation management. Regarding cargo handling work that cannot be carried out to store or transport products, the conventional hoisting method has been drastically changed to a lifting method, and the management systems of factories and warehouses have also adopted a lifting method and their layouts have been set, and forklifts have been used for cargo handling work. It has become mainstream to use .

A transportation management system that uses forklifts for cargo handling operations involves creating a three-dimensional storage space in a warehouse, specifically installing multi-level shelves, lifting products with forks, and transporting them to a higher shelf. This is the method of entering.

[Problems to be Solved by the Invention] However, when using a transportation management system using a lifting method, a storage space for articles and a running space for a forklift are required in the warehouse.

Furthermore, in order to efficiently load and unload articles onto and from the shelves, forklift running spaces must be formed vertically and horizontally within the warehouse with appropriate separation between the rows of article storage spaces within the warehouse.

Not only is it necessary to secure space for forklifts to run within the warehouse, but space for storing goods is also reduced. Another problem with using a forklift is that it requires a variety of movements when loading and unloading items. When picking up and transporting items from shelves, a worker drives a forklift from the entrance of the warehouse to the front of the shelf where the item is stored, and picks up the item from one of the shelves onto the fork. However, when loading goods onto the forks and unloading them, it is necessary to move the forks up and down.
When traveling in a warehouse, it is not always possible to travel in a straight line between the entrance of the warehouse and the shelves. This problem is not just a time loss, but also a major hindrance to the automation of transportation management. However, depending on the type of goods to be handled, it may be necessary to adopt this system, but it is not necessarily advantageous in terms of transportation management to use a forklift for all products. For example, paper rolls, barretized products, and the like are articles that have a fixed shape, have high strength, and can be stacked.

An object of the present invention is to provide a system that facilitates and automates transportation management by using a conventional lifting mechanism for handling fixed-sized articles that can be stacked.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a method for managing the transportation of free-standing articles, in which fixed-sized articles that can be stacked are transported into and out of a warehouse or an article storage area on the premises using an overhead crane. The storage area for items is divided into rows and columns for each area required for storing individual items, and the overhead crane stops at an arbitrarily designated position above the area. The system is controlled in such a manner that specific articles carried in by an overhead crane are stored in a stack of at least two or more layers within a designated compartment, or the articles are carried out from a designated compartment.

Furthermore, the self-standing article transportation management device according to the present invention is a self-supporting article transportation management device having an overhead crane, an article storage area, and a control device for the overhead crane, wherein the overhead crane has an article storage area and an unloading area. The storage area is located within the warehouse or site where the items are placed, and the item storage area is divided into rows and columns for each area required for storing the items. The overhead crane control device controls the operation of the overhead crane and also controls the stopping position of the overhead crane by specifying any one of the sections set in the goods storage area. Above the article placement surface in the article storage area, storage space and crane movement space necessary for stacking at least two or more articles are secured.

[Example] Examples of the present invention are shown below.

FIG. 1 shows the layout of a warehouse to which the system of the present invention is applied.

In the figure, ■ is a warehouse. As shown in FIG. 2, an overhead crane 2 is installed on the ceiling of the warehouse 1, spanning the entire floor of the warehouse 1, and the overhead crane 2 moves goods from the entrance 3 of the warehouse 1 to the goods storage area 4 on the floor. In this system, the goods lifted from the goods storage area 4 are transported to the entrance 3 of the warehouse 1, and the layout is as follows: The structure consisting of a club 7 that moves horizontally and a hanging fitting 8 suspended from the club 7 is the same as that of the conventional one. However, in the present invention, a robot suitable for automating the operation of grasping an article is used for the hanging fitting 8.

In the present invention, in order to store regular-sized articles to be stored in the article storage area 4 in a stacked manner of at least two or more stages, there is an article storage space R1 above the article storage area 4, and a crane can be moved above the article storage space R1. It is necessary to secure the space Q2, but this is not unique when using an overhead crane for boat fishing, and when goods are stacked in multiple tiers, it is necessary to secure the space Q2. This means that it requires height.

The article storage area 4 is located in the traveling direction (row direction) of the crane girder 6.
and the running direction (column direction) of the club 7 are divided into intervals necessary for placing articles, and the row direction positions (1, 2,
..., M) and the column direction position (1, 2, ..., N)
is set by Section [1, 11, [1, 2],
[2,11° [2,2], ... [M, Nl is formed.

The overhead crane 2 is controlled by the control device 9 to control the crane girder 6.
In the present invention, the control device 9 further controls the stop position of the overhead crane 2 to move the hanging tool 8 into any designated section [m, n) Function to stop directly above and hanging fitting 8
It has the function of opening and closing to grasp or release objects.

These controls are operated manually or by computer instructions.

In the embodiment, an example of storing and transporting regular shaped articles that can be stacked will be described.

FIG. 1 shows that regular shaped articles P are already stored in each compartment of the article storage area 4.
In each compartment, articles P are stacked in two or more stages as shown in FIG.

When an article P stored in an arbitrary section [m, nl is to be carried out, the controller 9 is used to command the crane to move onto the section [m, nl]. overhead crane 2
In response to the command, the hanger moves over the article storage area 4, and the hanging fitting 8 stops on the section [m, nl. Next, the hanging fitting 8 is lowered into the storage space Ql to capture the topmost article P in the compartment [m+n], lifted into the crane movement space Q2, moved as it is to the entrance 3 of the warehouse I, which is the unloading station, and moved to the warehouse I. Truck 1 is waiting at entrance 3 of 1.
Loading and unloading on 0. In the case of storing articles, the exact opposite operation can be performed. That is, the articles P loaded on the truck 10 can be carried into designated compartments [m, nl, stacked sequentially to the required number of stages, and further stored in two or more compartments.

In the present invention, in each compartment, the items are clearly stored, for example, by type of item, shipping time, and destination. This makes it possible to classify, for example, items within the range [1, +1 to [m, nl] are shipped to X in what month and what day. The control device can be operated by a computer, and if data on the processing content for each compartment is input, in the case of shipping, only the items in the compartment determined by data processing will be selected and transported automatically. It is possible to
Furthermore, it is of course possible to designate a section in which the articles loaded on a truck are to be stored and store them in multiple stages in a concentrated manner within the designated section.

[Effects of the Invention] As described above, according to the present invention, it is possible to easily manage the transportation of fixed-sized articles that can be stacked by utilizing conventional lifting-type loading machines, and in particular, transportation management can be performed by computer processing. It is a system that can automate the process of transporting and storing specific products, greatly simplifying the management process for transporting and storing them.

Further, according to the present invention, since the space above the article storage area is used to carry in and take out articles, it is necessary to secure a running space for the loading machine as in the case of using a lifting type loading machine. Moreover, since the articles are stored in multiple stages throughout the article storage area, the limited space can be utilized to the fullest. The present invention is of course applicable not only to warehouses but also to sites without continuous rooms.
