[Problem that the invention seeks to solve]

However, the conventional article handling methods and devices described above have the following problems.

That is, in JP-A-59-12005, the case body can be supplied quickly and efficiently, but an extremely large crane body is required.

Furthermore, in JP-A No. 59-118603, the conveyor is composed of a swinging frame and a horizontal fixed frame, and a single belt is wound around both frames, so that these are integrally constructed. In particular, when adapting to high-rise storage facilities, it is necessary to determine the slope of the swing frame within a slope that does not cause the articles to fall, in accordance with the height of the top shelf. Therefore, the length of the swinging frame has to be extremely long, and as a result, the installation space for the storage equipment requires the width of the storage equipment's frontage plus the length of the swinging frame, which is extremely long. A large dead space will be created.

In addition, in Japanese Patent Application Laid-open No. 59-182104, the size of the crane body can be reduced and the dead space can be reduced, but the articles must be transferred one by one to the receiving section of the vertical circulation conveyor in a timely manner. However, despite the need for complex control, there is a limit to conveyance capacity.

Furthermore, in Japanese Utility Model Publication No. 47-33170, there is no description of automatically loading or unloading articles into or out of an article storage facility.

Moreover, in Utility Model Publication No. 56-4650, in particular,
When adapting to high-rise storage facilities, the slope of the telescoping frame must be determined to match the height of the top shelf and within a slope that will not cause items to fall over, so the length of the telescoping frame must be extremely long. As a result, the dispensing port must be located very far from the end of the storage facility, resulting in an extremely large amount of dead space.

In addition, in Utility Model Application Publication No. 50-113178, articles cannot be handled continuously.

Further, in Japanese Utility Model Application Publication No. 59-37206, the structure of the storage facility is limited because the transfer device is not provided with a traveling function.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an article handling method and apparatus that allows articles to be handled efficiently, quickly, and continuously without creating a dead space around a storage facility.

14 and 15 show another centering mechanism in the warehousing device 32', and the illustrated centering mechanism is an alternative to the centering guide 32'' that centers the articles from one side as shown in FIGS. 5 and 6. A pair of conveyors 6 from both sides,
6 to center the article. That is, the pair of conveyors 6, 6 receives control information commands sent from a computer on the ground, such as the number of articles to be supplied, the article supply address (the frontage of storage facility A to which the articles are to be supplied), and the width dimension of the articles. The control cylinders 7, 7, operating on the basis of the control cylinders 7, 7, are adapted to center the article from both sides by varying their spacing.

The features of the embodiments and examples of the article handling method and apparatus of the present invention described above are listed below.

The running of the stacker cranes without installing the article transport conveyors such as the article loading conveyor E and the article carrying out conveyor C on the running path of the stacker cranes such as the stacker crane D on the warehousing side and the stacker crane B on the exit side. Since the article transfer conveyor can be installed parallel to the storage facility and at the intermediate level of the storage facility, the article transfer conveyor can be used with an upward slope, horizontal slope, downward slope, etc. The total length of the crane can be shortened to reduce the dead space.

●Since the article transfer conveyor and article transport conveyor are separate bodies, each can be started, stopped, or speed controlled separately, allowing control over a wide range of warehousing and unloading of articles.

●After taking out the goods from any opening of the storage facility, the goods are simply sent to the goods transfer conveyor via the goods transfer conveyor, which allows for simple and highly efficient unloading. Further, even when the stacker crane is running, the articles on the article transfer conveyor that have already been taken out from the storage facility can be transferred to the article transfer conveyor, so that the efficiency of unloading is good.

●Items can be loaded into the storage facility by simply receiving the items sent from the article conveyor onto the article transfer conveyor and transferring them to the warehousing device.

●Traditionally, loading and unloading was carried out by moving the Statzker crane back and forth between the loading station (cargo delivery area) and the frontage of the storage facility, so the Statzker crane was always empty on one trip. Therefore, in addition to being inefficient, the reciprocating distance of the stacker crane is long, which wastes more time. However, in the present invention, articles are constantly transported on the side of the running surface of the stacker crane. Since there is a conveyor and the article transport conveyor can be used in place of the loading station, there is no need to move the stacker crane back and forth between the loading station and the frontage of the storage facility.
In other words, in the present invention, the article conveyor is used like a moving loading station, and articles can be delivered to the vicinity of the stacker crane, for example, by type, despite the movement of the stacker crane.

The article handling method and device of the present invention may be applied to either warehousing or unloading of a storage facility, and can also be applied to warehousing or unloading of a single type of article. ,In any case,
The invention is not limited to the embodiments and examples described above.

〔Effect of the invention〕

As described above, the article handling method and device of the present invention have great effects such as being able to efficiently, quickly and continuously handle articles without creating a dead space around the storage facility. Ru.
