Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a system for carrying in and out of the largest length materials for storing and sorting various kinds of long materials received from a steelworks before delivery, and more specifically, the present invention relates to a system for carrying in and out of the largest length materials before delivery. By combining with a central computer, we can control the operation of mirror cranes, transport vehicles, yard cranes, etc., and centrally process long material information and scheduling to speed up the loading, storage, and unloading of long materials. The present invention relates to a system for carrying in and out of long materials that can be carried out smoothly.

In general, steel materials sent from steel mills have extremely diverse attributes such as shape, dimensions, and quantity, and each steel material is accompanied by complex information such as order destination, quantity, and deadline. There is. Conventionally, the handling of these steel materials and information processing have all been done manually. For example, at a quay, a quay manager fills out a form and gives work instructions to the unloading crane driver.

Also, based on this form, the destination of the transport vehicle is determined and work instructions are given to the driver. In the evening, at the storage yard, the warehouse manager gives instructions to the yard crane driver while checking the documents. In this way, the subordinate steel yards are under the control of these managers, and the operation of each cargo handling equipment and the processing of steel information are carried out over a vast area and a vast amount of land. This was a very labor-intensive and labor-intensive task in terms of moving heavy objects.In the method of handling steel materials, which relies on manual work management and information processing as described above, it is difficult to handle steel materials when the scale of the steel storage yard is small. Z is not a problem, but as the scale of steel storage yards has become larger in recent years, and the properties of steel materials have become more diverse, it not only requires a great deal of labor, but also leads to management errors. Smooth operations will be hindered, and there is a risk that not only will the processing capacity of the storage yard as a whole decrease, but also the service to customers will deteriorate.On the other hand, compared to the above-mentioned steel materials, the properties of objects handled such as containers For example, the automatic yard described in Japanese Patent Publication No. 52-118262 has been proposed as an automated yard for automating the constant cargo handling and information processing. For things like cargo, ``There is no example of a system that has been constructed that is suitable for this, and the reality is that many small-scale steel yards that rely on extremely messy manual labor have been installed.

3. The present invention smoothly carries out a series of operations in the storage yard where long materials received by ship are unloaded, transported to the storage yard, stored, and the largest materials are transported to the customer. The purpose of the present invention is to provide a long material loading/unloading system that achieves significant labor savings in information processing and operation control of cargo handling machines, and also enables sufficient service to customers. The present invention enables the above-mentioned equipment to be controlled accurately and organically by connecting online a central computer unit having four control functions for directly controlling the loading/unloading crane, the first and second transport vehicles, and the yard crane. input of long material information for this purpose,
This makes it possible to centrally manage inventory location data, etc.

As a result, based on the information on the long villages unloaded by the unloading crane, the placement of the storage yard is determined, the destination of the first transport vehicle is instructed, and the storage operation of the yard crane is subsequently controlled. A series of operations such as instructing the destination of the second transport vehicle based on the delivery information and subsequently controlling the delivery work of the yard crane is carried out smoothly.Examples of the present invention will be described below with reference to the drawings. explain.

In this figure, the unloading crane 6 has legs 18 that can run along the wharf 4, a land-side girder 19, and a sea-side girder 20. A landing device 21 and a land tin device operation control device 22 are installed on the sea side girder 20, and the steel material 5 of the ship 3 can be unloaded onto the storage device 23 in the leg 18.
Furthermore, the land side girder 19 is equipped with a transfer device 24 and a transfer device operation control device 25, and the steel materials 5 on the storage device 23 can be unloaded onto a stopped trailer.
A work command for landing work is transmitted to the landing equipment operation control system 22 from a work command unit 26 connected to the central computer 17. Further, information directly related to each steel material 5 read at the time of landing or transfer to the trailer 7, such as model number, quantity, customer information, etc., is stored in the steel material information input unit 2.
7, the information is transmitted to the central computer 17, and is compared with the supplementary information received in advance. Based on these results, the destination instruction unit 28 instructs the trailer 7 to a predetermined storage yard 11 for storage, so that even a small number of trailers 7 can be used efficiently and smoothly. Figure 3 shows
