Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gate system for automatically measuring the weight of a container transport vehicle by a platform scale at an entrance gate of a container yard.

[0002]

2. Description of the Related Art In a container yard, a platform scale for measuring the weight of a container transport vehicle is provided in front of an entrance gate. This is because a difference between the actual weight of the container and the declared weight affects the loading freight and the loading weight of the ship carrying the container.

Conventionally, the weight of the container is measured by a worker who performs reception work at the entrance gate, reads the weight of the container transport vehicle displayed on the weight indicator of the platform scale, and determines a predetermined tare weight from the read weight. That is, the weight is obtained by subtracting the weight of the container transporting vehicle in the non-loaded state of the container, which is the sum of the weight of the container mounting chassis and the weight of the chassis towing truck.

[0004]

In the conventional system, in order to measure the weight of a container, an operator visually checks the display weight on a weight indicator of a platform scale and performs the calculation manually. Therefore, it is necessary to have a worker resident at the entrance gate, so that it is not possible to achieve unmanned operation and labor saving, and reliability is reduced due to calculation errors. In addition, since it takes time to calculate the container weight, re-measurement of the weight due to a calculation error requires more time. It lowers the work efficiency of the worker who performs the receiving process such as the computer processing of the data described in the class, and adversely affects the container processing capability at the entrance gate.

An object of the present invention is to provide a container yard gate system that can solve the above-mentioned problems.

Machine.

A measurement area 3 is provided in front of the entrance gate 1, and a check area 4 is provided in front of the measurement area 3. A platform scale 6 for measuring the weight of the container transport vehicle 5 is provided in the measurement area 3. The platform scale 6 has a display unit 6a for displaying a measurement result.

A vehicle detection sensor 9 for detecting the presence or absence of the container transport vehicle 5 on the platform scale 6 is provided. The vehicle detection sensor 9 only needs to be able to detect the vehicle 5 existing on the platform scale 6, and can be constituted by a non-contact type sensor such as a proximity switch or a photoelectric switch.

The platform scale 6 is connected to the terminal computer 11 using the display unit 6a as a communication interface.
The vehicle detection sensor 9 is also connected to the terminal computer 11.

The terminal computer 11 is arranged in a document processing booth D provided along the check area 4,
The input device 12 and the display device 13 are connected. The checker, who is a worker in the container yard, sends a container C transported by the container transport vehicle 5 from a driver of the container transport vehicle 5 stopped in the check area 4.
Is received from the input device 12 to the terminal computer 11 in the document processing booth D, for example, the driver name of the container transport vehicle 5, the shipper name of the container C, and the container C. Container attribute information such as an identification code is input while confirming the input content on the display device 13. The input device 12 includes a keyboard for inputting attribute information such as container dimensions and an identification number by key operation, a scanner for reading items described in the carry-in / out slip, and a storage medium in which the carry-in / out slip stores container attribute information. If it is, it can be constituted by a device for reading the storage medium. In the check area 4, the checker checks the container C. For example, the dimensions of the container C, whether the container C is an actual container or an empty container storing luggage,
The degree of damage and the position of damage are checked. The checker also inputs data corresponding to the check result of the container C from the input device 12 to the terminal computer 11.

In a printer booth P provided along the measurement area 3, a printer 10 is provided as an entry permit issuing device. The printer 10 is connected via a LAN to a management computer 16 in the container yard. When the vehicle is stopped so that the driver's seat is located beside the printer 10, the container transport vehicle 5 is placed on the platform scale 6.

The terminal computer 11 stores the weights of the plurality of types of container transport vehicles 5 in a state where no containers are loaded, in association with the types of the respective container transport vehicles 5. From the input device 12, the container transport vehicle 5
It is possible to input the vehicle type signal corresponding to each type to the terminal computer 11. For example, the input device 1
A different vehicle type is associated with each of the plurality of key switches of the keyboard constituting the keyboard 2, and a corresponding signal is input by operating each key switch. Further, the processing request signal is transmitted to the terminal computer 1 by the input device 12.
The processing request signal is input by operating a specific key switch of a keyboard constituting the input device 12, for example.

After the processing request signal is input, the terminal computer 11 calculates the processing request based on the weight measured by the platform scale 6 immediately after the container detection vehicle 9 has not been detected by the vehicle detection sensor 9. The weight of the container is calculated by subtracting the weight stored in association with the type of the container transport vehicle corresponding to the vehicle type signal input immediately before the signal is input.

The terminal computer 11 sends the attribute information, the damage check result, the calculated container weight, etc. of the container C to be stored to be stored by the container transport vehicle 5 to the management computer 16 in the container yard via the LAN. Send the data. A display device 14 and an input device 15 operated by a clerk who is an operator of the container yard are connected to the management computer 16.

The management computer 16 collates the container attribute information input to the terminal computer 11 with data stored in advance, and from the collation result, the clerk indicates that the container C is scheduled to enter the container yard. Confirm that the container C in the container yard
A reception process for obtaining the placement position and the like is performed. A form in which the result of the reception processing such as the collation result, the placement position, and the check result of the container C is described is printed out from the printer 10 as an entry permit. The calculated container weight is also transferred to the printer 10 and the display device 1 by the management computer 16.
3 is output as the operation result.

The driver of the container transport vehicle 5 receives the printed output form by self-service. The management computer 16 is connected to the vehicle regulation device 2,
After the entry permit is output, the vehicle regulation device 2 may be changed to the entry permission state, and when the vehicle 5 is no longer detected by the vehicle detection sensor 9, the vehicle regulation device 2 may be changed to the entry prohibition state.

In the above configuration, the container transport vehicle 5 that transports the container C to be stored in the container yard is first stopped in the check area 4 in front of the document processing booth D, and the driver passes the carry-in / out slip to the checker. The checker checks the data corresponding to the items on the
A check result such as damage to the container C is input to the terminal computer 11 using the input device 12. Next, the checker determines the type of the container transport vehicle 5 and inputs a vehicle type signal to the terminal computer 11 by operating a key switch of the input device 12 corresponding to the type. Next, when the processing for the container transport vehicle 5 in the check area 4 is completed, the checker inputs a processing request signal to the terminal computer 11 by operating a key switch of the input device 12. In addition, the driver moves the container transport vehicle 5 from the check area 4 to the measurement area 3 according to an instruction from the checker.
And placed on the platform scale 6. As a result, after the processing request signal is input, the terminal computer 11 obtains the processing request signal from the weight measured by the platform scale 6 immediately after the container detection vehicle 9 has not been detected by the vehicle detection sensor 9. A container weight is calculated by subtracting the weight stored in association with the type of the container transport vehicle corresponding to the vehicle type signal input immediately before input. Here, the vehicle detection sensor 9
After the container transport vehicle 5 is detected by the above, after a predetermined time elapses until the weight measurement value of the container transport vehicle 5 by the platform scale 6 elapses, the terminal computer 11 calculates the weight measured by the platform scale 6 Read. When the container transport vehicle 5 is detected by the vehicle detection sensor 9 at the time when the processing request signal is input, the container transport vehicle 5 is not detected until the container transport vehicle 5 is detected.
The calculation of the container weight is not performed. Thus, when another container transport vehicle that precedes the container transport vehicle 5 that originally measures the weight is placed on the platform scale 6, the container transport vehicle that should originally measure the weight of the other container transport vehicle 5 can be prevented from being erroneously measured as the weight of 5, and the reliability of the weight measurement can be improved. Next, the terminal computer 11 transmits data such as the attribute information of the container C to be stored, the damage check result, and the calculated container weight to the management computer 16 via the LAN. Clark performs the above-described reception processing based on the data transmitted to the management computer 16. When the receiving process is completed, Clark operates the input device 15 to cause the management computer 16 to print out a form describing the result of the receiving process including the calculated weight of the container C from the printer 10 as an entry permit. Upon receiving the entry permit, the driver confirms that the vehicle control device 2 is in an entry permission state and starts the container transport vehicle 5,
Enter the container yard from entrance gate 1. As a result, the container transport vehicle 5 disappears from the platform scale 6, so that the vehicle detection sensor 9 is turned off, and the next container transport vehicle 5 can be weighed. By repeating the above, the container transport vehicle 5 sequentially enters the container yard from the entrance gate 1.

According to the above configuration, since the weight measurement of the container C can be automated, the checker in the check area 4 can concentrate on the work such as the damage check of the container C, and can reduce the work load and improve the work efficiency. Speedup and labor saving can be achieved. In addition, there is no calculation error at the time of weight measurement, and while the weight of the preceding container transport vehicle 5 is being measured in the measurement area 3, the type of the subsequent container transport vehicle 5 is checked in the check area 4 and the damage is checked. Since the work can be performed, the work efficiency can be improved, and furthermore, the preceding container transport vehicle 5 is not erroneously recognized as the target of the weight measurement of the succeeding container transport vehicle 5, and highly reliable and quick container processing can be performed. .

The present invention is not limited to the above embodiment. For example, the display unit 6a of the platform scale 6 is not essential, and the platform scale 6 may be connected to the terminal computer 11 via a dedicated communication interface.

[0022]
