Abstract

PURPOSE:To shorten the time to load a ship fully by equipping a transport facility to connect a coal discharge facility with a shipping facility, and thereby transporting the coal from the wagons, by which the coal has been sent into the yard, directly into the ship. CONSTITUTION:Conveyor belts 14, 16 are installed to connect a car dumper with a ship loader, and thereby coal unloaded by the car dumper is sent into the ship directly without a step of placing at the yard. As the capacity of a train is much less than that of a ship, information about ship arrival is acquired in advance, and a train or trains with the same item of cargo as the chip requesting according to the acquired information are put in stand-by at a sidetrack 26 till the ship arrival, and then the train is introduced to the car dumper. Thereby the direct loading can be operated efficiently to ensure a shortened time for loading a ship.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to a coal shipping base coal yard system.

In general, a coal yard system must satisfy the following points in terms of its equipment configuration.

■ Equipped with coal transport equipment that can directly transport coal from coal unloading equipment to coal loading equipment.

■ The capacity of coal unloading equipment is higher than the capacity of coal cutting equipment (equipment that cuts coal from the coal pile on the yard).

■　Has a stop for coal delivery vehicles.

[Prior art]

The coal shipping terminals before the coal review were small in scale, and there was no precedent for a coal yard system that included total operation.

In the past, direct shipping was limited to emergencies such as when cutting equipment broke down.

Regarding the placement method of brands, conventionally, it was common to fix the placement location for each brand.

[Purpose of the invention]

An object of the present invention is to provide a coal shipping base coal yard system that enables shortening of ship demurrage time.

Overview of a coal shipping base coal yard The cargo handling operations and coal flow in a large-scale coal shipping base coal yard equipped with large-scale loading machinery will be explained using Figure 1.

Coal is transported from Yamamoto by special coal train 31. The arriving coal-only train (hereinafter simply referred to as a train) is positioned at car damper (Cd) 1.2. car damper 1,
2 is a device that overturns the loading platform of a train in units of one to several cars and dumps coal into the hopper below.

A stacker (st)a is a device that piles up coal in a yard.
~6.

In parallel with the arrival of the train, the stackers 3 to 6 move to predetermined coal loading positions, and the conveyor group switches routes so that the coal flows from the car dampers 1 and 2 to the stackers 3 to 6.

When these preparations are completed, the car dumper overturns the loading platform in units of several cars, and the dropped coal passes through the conveyor, and on the way,
The weight is measured by the scales 21 and 22, and the stacker 3
~6 piles up on the yard. After unloading all the coal from the cars, the train departs for Yamamoto. The above is the acceptance work.

A pile of coal piled up in a yard is called a pile.

Coal is transported by a coal vessel (hereinafter simply referred to as a vessel). Ships that arrive with empty cargo are transported to Perth (quay).
Arrive at 20. When we docked, we tied a rope to the boat,
Cargo handling preparation work such as opening the no-tsuchi will be carried out. In parallel with this, ship loaders (equipment for loading coal onto ships)
St) lo.

11 moves to a predetermined hatch, and reclaimers (Rc) 7 to 9, which are devices for cutting out coal from the pile, move to the pile to be cut. The conveyor group switches routes so that coal flows from the reclaimer to the ship loader.

Once these preparations are complete, the reclaimer continuously cuts out the coal. The cut coal passes through a conveyor, and along the way, its weight is measured by scales 23 and 24, and then loaded onto a ship by a ship loader. Once loading is complete, the no-tsuchi is closed and the ship leaves the berth and departs from port. The above is the shipping work.

Operational purpose and method of operation of a coal shipping terminal The main purpose of operating a coal loading terminal is to shorten the time a ship spends in port (hereinafter referred to as vessel dwell time).

The reason for this is as follows.

Ships are expensive to build, so shipping companies strive to operate their ships efficiently in order to be profitable. This is because loading and unloading at a port takes time, and if departure from port is delayed, the efficient operation of the ship will be hindered.

[Summary of the invention]

The present invention is characterized by using the following two operations to achieve the above object. The first is direct delivery, and the second is the distributed placement of brands.

Direct shipping means that the coal unloaded by a car dumper is loaded directly onto a ship without being piled up in a yard. For this purpose, as shown at 14.16 in FIG. 1, a bare route is installed to connect the car damper and the ship loader. If the capacity of the car damper is higher than that of the reclaimer, the cargo handling time required for loading will be shorter if the cargo is removed from the pile or sent directly.

Since the carrying capacity of a train is small compared to the carrying capacity of a ship, the arrival cycle of a train is shorter than that of a ship. The number of trains that can arrive directly while a ship is unloading cargo (that is, loaded with the same brand as that ship's requested brand) is small. Therefore, the ship's arrival schedule information is obtained, and a train loaded with the same brand as the requested brand is stopped at the siding track 26 in advance. Direct delivery can be made even more effective by placing the train in a car dumper after the ship arrives.

Dispersion of stocks means creating inventory in each yard for every brand, and equalizing the stock amount of each brand by yard. As a result, when a ship requests a certain brand, it can be simultaneously unloaded from multiple yards, reducing the cargo handling time required for loading.

Distributed placement of brands can be achieved by giving priority to yards with a small inventory of the brand at the time of loading, and by giving priority to yards with a large inventory of the brand at the time of discharging. In addition, in general coal yards, in order to facilitate inventory management, a fixed yard is used for each brand.

By performing these two operations, it is possible to shorten the time on board.

[Embodiments of the invention]

The configuration of the system will be explained using FIG.

The ship's required brand setting panel 41 is located in the operator's room.
It is electrically connected to the computer 40. When the operator sets the ship number and requested brand to 41, the information is transmitted to computer 40 and entered in file 51.

The railyard board 42 is located at the operating station and is electrically connected to the computer 40. When the staff member sets the train loading brand and train number on the board 42, it is transmitted to the computer and entered in the file 52. In addition, the siding line for 26 people/car damper line for 25 people line signals and the next processing train number are displayed on the calculator 4.
It is transmitted from 0 to this board 42.

Each loading device 1 to 18 is electrically connected to a computer,
The operating status is transmitted to the computer and entered in the file 54. In addition, signals such as loading commands to piles, cutting commands from piles, and direct delivery commands are sent from the computer to each loading device.

The weight scales 21 to 24 are electrically connected to a computer, and the inventory management file 53 is updated based on the measured values.

The computer 40 is composed of files and modules as shown in FIG. A flowchart of each module is shown in FIG.

Next, the operation of this system will be explained.

The operator communicates with the ship and obtains information on the ship's expected arrival date and requested brand. When the scheduled arrival date approaches within the reference number of days, the operator sets the ship name and requested brand on the ship requested brand setting panel 41. The computer 40 updates the ship brand file 51 based on the information.

When a train arrives from Yamamoto, the marshalling yard staff sets the train number and loading brand on the marshalling yard board 42.

The computer 40 first updates the train brand file 52 based on the information. Next, module 60 is activated. Check whether there is a ship that requires the same brand as the one loaded on this train. If there is, please put this train on siding track 26.
A siding line entry signal is transmitted to the train yard board 42. If there is none, a damper line entry signal is sent to the yard board in order to put the train into the car damper line 25. At the same time, file 55 or 56 is updated.

The operator steers the train based on the siding line entry/car damper line entry signal displayed on the operating station panel 42.

When a train departs from the car damper and the car damper becomes vacant, the computer 40 activates the module 61 and displays the train number to be processed next on the operation board 42.

Based on this, the operator places the train in the car damper.

When the train enters the car damper, the computer 40 activates the module 62. The module 62 issues a work order to the equipment if direct delivery is possible (that is, the brand requested by the ship is equal to the brand loaded by the train, and the equipment capable of direct delivery is vacant), and if direct delivery is not possible. If this is the case, priority is given to a yard with a small inventory of the brand loaded on the train, and a work order is issued to the appropriate stacker.

When the ship arrives and completes docking at Perth, the computer 40
starts modules 62 and 63fc.

If the brand of the train being processed by the car damper is the same as the brand requested by the ship, a command is issued to carry out direct delivery. Further, priority is given to a yard with a large inventory of that brand, and commands are given to payout from a plurality of piles.

It should be noted here that even if the brand of the train being processed by the car damper is different from the brand requested by the ship, when the train departs, the module 62 is activated and the brand requested by the ship is changed. This is the point where instructions are given to place the loaded train into the car dumper. This allows direct delivery to be carried out with high frequency.

〔Effect of the invention〕

According to the present invention, it is possible to carry out direct shipping with high frequency and simultaneously pay out from a plurality of piles, so it is possible to shorten ship time.
