DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
Using a container crane 4 for unloading and unloading the container 3 from the container ship, a transfer crane 7 for loading the container 3 in the storage area 1B, and a container handling machine such as a transfer machine (not shown) When carrying out the cargo handling of the containers 3, the confirmation work of each container 3 is performed by an operator who is boarding the cargo handling machine for containers, a worker engaged in the cargo handling, or the like.

More specifically, a container number is written on the wall surface of the container 3 in advance. While checking the container number with the cargo handling plan of the container 3, where the AGV 5 or the trailer 6 needs to be carried.
It has been confirmed whether it should be loaded on the container ship or at which position on the container ship 2 it should be loaded. Then, after the working conditions of the cargo handling are confirmed, loading, unloading, loading, unloading, transfer, etc. on the container 3 are performed.

However, since the operator and the operator confirm the container number, a large number of personnel are required at each cargo handling site, and a lot of labor is required for the cargo handling work. In addition, when handling a large number of containers 3, a confirmation error may occur.
It is necessary to redo the packing. This is a major factor in lowering the cargo handling efficiency. Further, in the confirmation by a worker or the like, since the confirmation work requires a certain amount of time, the cargo handling work has to be temporarily stopped, and similarly, the cargo handling efficiency is reduced.

Further, it is necessary to manage as a history together with a pre-planned cargo handling plan to manage when and where the container 3 is loaded by which cargo handling machine and where it is actually located. Since such a recording work is manually input by a worker, it takes a great deal of effort to manage the history of the container 3.

The present invention has been made in view of the above circumstances, and recognizes information on a container for cargo handling quickly and automatically and reduces the work of checking the container during cargo handling to improve the efficiency of cargo handling work. An object of the present invention is to provide a container handling machine and a container management system capable of easily performing history management of the container.

[0009]

In order to solve the above problems, the present invention adopts the following means. According to a first aspect of the present invention, in a container handling machine that includes a lifting device that holds a container and handles the container, a data reading unit that reads container information stored in a data carrier attached to the container is provided. It is characterized in that it has a communication device.

As the container information, for example, container identification information, container shape information, type of normal or frozen container, type of load in container, load sender and place of load, load receiver and destination, weight of load For example, information such as storage of containers, place of packing, frequency of use, etc. can be given. Container information relating to such a container is stored in a data carrier attached to the container, and this container information is read by a communication device having a data reading means provided in the container handling machine. Therefore, the container handling machine is
By recognizing the container information of the container obtained by the communication device, the cargo handling work of the container is performed. Therefore, it is not necessary for the operator of the container handling machine or the operator to confirm the container.

According to a second aspect of the present invention, in the container handling machine according to the first aspect, the communication device includes data writing means for writing new container information in the data carrier. I am trying.

As described above, since the communication device is further provided with the data reading unit in addition to the data reading unit, new container information relating to the cargo handling work is written in the data carrier. Then, the written container information is carried together with the container in accordance with the movement of the container, and is appropriately disclosed as necessary. Writing new container information means, for example, overwriting previously stored container information, or writing new information regarding cargo handling. For example, as the newly written container information, there is container information such as a history of cargo handling, a place where the container is stored, or a change in the already stored storage place. The data writing means and the data reading means are
Although it is configured as one component of the communication device,
The data carriers may be provided at different positions depending on the installation location and the number of installations, or may be configured together.

According to a third aspect of the present invention, in the container handling machine according to the first or second aspect, the communication device is provided in a hanging device that holds the container.

Since the hanging device is provided with the communication device having at least the data reading means for reading the container information from the data carrier, the container information is always transmitted to the communication device at a short distance. this is,
This is because the container and the suspension device are necessarily close to each other during the cargo handling work.

According to a fourth aspect of the present invention, in the container handling machine according to the third aspect, the communication device corresponds to the data carrier provided substantially at the center of the upper surface of the container, and the communication device is the suspension device. It is characterized in that it is provided substantially at the center of the lower surface.

The communication device needs to reliably obtain the container information from the data carrier. Therefore, by providing the container and the suspension device at the position closest to each other and at the position where the displacement between the suspension device and the container is smallest, the container information can be reliably stored in the data reading means of the communication device. Will be read by. Further, since the suspending device generally holds both ends of the container, the reading or the like can be performed in the substantially central part where the communication device is provided without interfering with the container. When the communication device is provided with the data writing means, the container information is surely written.

According to a fifth aspect of the invention, in the container handling machine according to any one of the first to fourth aspects, the container information is obtained from the communication device, and based on the container information. It is characterized by comprising an operation control unit for controlling the operation of each drive unit.

By sending the container information obtained by the communication device to the operation control unit, the container handling machine can
Based on the container information, the operation is performed according to the instruction of the operation control unit that controls the operation of each drive unit. It should be noted that each drive unit referred to here means an actuator serving as a drive source for operating the container handling machine.

For example, when the operation control unit obtains the container identification information as the container information from the data reading means of the communication device, the operation control unit causes each drive unit to move the container to a pre-planned target position. The operation instruction is issued to the user. Then, the container is automatically conveyed to the target position by the cooperation operation of the respective drive units. Further, when the load in the container requires careful handling, the operation control unit, which has obtained this information as container information, controls the operation of each drive unit so as to perform the operation according to the load. Even if a means for processing the container information or an intermediary device intervenes while the container information is sent from the communication means to the operation control unit, the container information is finally sent to the operation control unit. Any configuration is available.

According to a sixth aspect of the invention, in the container handling machine according to the fifth aspect, a winch for lifting and lowering the hanging device is provided, and the operation control unit obtains the container information from the communication device. In addition, the hoisting or lowering speed of the winch is limited based on the container information.

The operation control unit recognizes container information such as the weight of the container or the weight of the load stored in the container and the type of the load stored in the container, which is obtained from the communication device. The operating speed of the winch suspended and supported by the device is limited. For example, if the weight of the container to be lifted by the lifting device is too large, the operator has always carried out a driving operation with a reduced winch capacity in order to reduce the load on the winch. At this time, the operator recognizes the weight of the container when the ground is cut off, so that smooth cargo handling work has not been performed.

In the present invention, the weight of the container is recognized when the lifting device approaches and holds the container, and the operation control unit limits the operation of the winch without the operator's judgment. . Also, at the time of stopping due to lowering, depending on the weight of the container, an excessive load will be applied to the winch or the brake etc. provided on it,
It is also possible to reduce the load by limiting the winding speed in advance. In addition, regardless of the above, it is possible to cause damage to the container and load during cargo handling, etc. by obtaining an appropriate speed for hoisting and lowering according to the weight of the container and the type of load, etc. Disappears. In addition, the winch is positioned as one of the respective drive units described in claim 5.

According to a seventh aspect of the invention, in the container handling machine according to any one of the first to sixth aspects, the moving route of the lifting device is stored as operation history data, and the operation history data is stored. And a data processing unit for collating the container information obtained from the communication device with the container information.

With such a configuration, the data processing unit obtains the container information of each container and stores the position of the container having the container information in the cargo handling work. That is, even in a large number of containers that are stacked in multiple stages and loaded or stored, the position of the container having the specific container information is stored.

According to an eighth aspect of the invention, in the container handling machine according to the seventh aspect, the operation history data and the container information are collated by the data processing unit to specify the location of the predetermined container. It is characterized by comprising an operation control unit for moving the suspension device to the location based on the position information.

With such a structure, the operation control unit uses the container for moving the lifting device to the target container based on the position information of the location of the container stored when the container is loaded. It controls the operation of the cargo handling machine. As the container handling machine including the operation control unit, for example, a transfer crane or the like that is operated in a storage area of a container that reloads the same container is particularly effective.

According to a ninth aspect of the present invention, there is provided a container handling machine according to any one of the first to eighth aspects, and the control management is performed for managing the respective containers based on the respective container information. It is characterized by a container management system that includes parts.

With such a configuration, the control management unit obtains the container information stored in the data carrier from the container handling machine and, based on the container information, places other than the container handling machine. That is, the state of each container is recognized and managed by the control management unit.

Further, in order to send the read container information to the container crane 4 main body, the ID tag reader / writer 45b is provided with a cable or wireless line for transmitting and receiving the container information.

The ID tag reader / writer 45b is
It is attached to the above position in order to surely receive the container information from the ID tag 3b. However, since the ID tag reader / writer 45b does not have to be close to each other depending on the reception / transmission capability of the ID tag reader / writer 45b, the mounting position of the ID tag reader / writer 45b is not limited to this.

The ID tag 3b is attached to approximately the center of the upper wall surface of the container 3, and is a magnetic storage medium as a structure. In addition, the container information stored in the ID tag 3b means that in each container 3,
Identification container number, container type such as frozen or normal container, container shape (total length, height, etc.), type of load in container, load sender and place, load receiver and destination, load weight, container Loading position on the ship,

Of these, the container number, container type, and container shape are fixed information and cannot be rewritten by the data writing means. In addition, other information such as the type of load in the container, the sender and place of the load, the receiver and destination of the load, the weight of the load, the loading position on the container ship, the scheduled storage location of the container, etc. The data writing means of the writer 45b can appropriately change, that is, update.

Next, the structure of this embodiment of the transfer crane 7 (container handling machine) shown in FIG. 2 will be described. The transfer crane 7 shown in a perspective view in the figure includes a spreader 75 for gripping the container 3 similarly to the container crane 4 described above. The spreader 75 is suspended from the trolley 72 that traverses the upper beam 71. Further, the trolley 72 is provided with a winch 73, and the spreader 75 is wound up and down. And the spreader 75
In addition, the ID tag reader / writer 75b according to the present invention,
It is attached in the same manner as the spreader 45 of the container crane 4 described above.

Next, the flow of the container information in the cargo handling work in the container handling machine such as the container crane 4 and the transfer crane 7 and the operation of each container handling machine will be described with reference to FIG. It should be noted that the contents described below are mainly described with respect to the container crane 4 shown in FIG.

FIG. 3 is a block diagram showing the container information written in the ID tag and the flow of operation control signals in the operation of the container handling machine based on the container information. It should be noted that this figure also illustrates the configuration of the container management system according to the present invention.

Reference numeral 100 shown by a broken line on the upper left side of the drawing indicates a management control unit for collectively managing the container terminals. Further, in the figure, the portion shown by the lower broken line shows the container handling machine 4, (7) such as the container crane 4 and the transfer crane 7 described above.

The container information to be written in the ID tag 3b can be appropriately written at the destination where the container 3 is carried. For example, as shown in FIG.
It is performed by an ID tag writer or the like having 1, 110, 120. Then, as one of the places for writing the container information, it is possible to write by the data writing means 101 under the control of the management control unit 100 that manages the container terminal.

The management control unit 100 manages the history of each container 3, the operating status of container handling machines such as the container crane 4 and the transfer crane 7, and the operating status of the AGV 5 (see FIG. 4) and trailer. There is also. The data writing unit 101 is provided at the loading / unloading gate of the container terminal, and can write the container information to the ID tag 3b of the container 3 carried into the container terminal.

The container information to be written here is information on a cargo handling plan preliminarily planned at the container terminal such as at which position the container 3 is stored in the container terminal or at which position of the container ship 2 is loaded. , Data management unit 102 to data writing means 1
It is written in the ID tag 3b via 01. The data management unit 102 has an input unit for inputting the information of the cargo handling plan and the like, and a display unit 102b for displaying the input information.
And at least.

When the container crane 4 starts loading the container 3 onto the container ship, the container information stored in the ID tag 3b is read by the ID tag reader / writer 45b attached to the spreader 45 provided in the container crane 4. To be Then, the read container information is sent to the data processing unit 55.

The data processing unit 55 obtains the container information of each container 3 so as to have a function of prompting an instruction to automatically move the container 3 having the container information to the target position, and in the cargo handling work. It has a function of storing whether the container 3 has been moved to the position. The steps will be described below in order.

The loading position information on the container ship 2, which is one of the container information obtained by the data reading means 56, is processed by the data processing unit 55 and then each driving unit 58.
Is sent to the operation control unit 54 that controls the operation of the. As a result, the operation control unit 54 of the container crane 4 prompts each drive unit to operate so that the container 3 reaches the loading position on the container ship 2, and the automatic cargo handling work by the container crane 4 is performed. Will be seen.

More specifically, if the loading position on the container ship 2 is stored in the ID tag 3b as a coordinate system, the data processing unit 55 stops the trolley 42 and winches 47. After being processed into data such as the winding height, this data is obtained by the operation control unit 54, and the operation of the drive motor for driving the trolley 42, the winch, etc. is controlled. Then, the spreader 45 holding the container 3 automatically reaches the target position.

Further, when the container information of the container 3 enters the data processing unit 55 at the start of the cargo handling, the data processing unit 55 causes the operation control unit 54 to drive the operating states of the trolley 42 and the winch 47 in the cargo handling. Import as history data and start storing. And the container 3
When the cargo lock of the spreader 45 is finished and the twist lock pin 45a of the spreader 45 is released to separate the container 3 from the spreader 45, the container information cannot be obtained from the ID tag 3b. The acquisition of the operating state from the unit 54, that is, the storage of the operation history data is ended.

As a result, in the data processing unit 55, the operation history data and container information such as the container number of the container 3 are used to determine where the container 3 gripped by the spreader 45 is placed and through which movement route. It will be memorized after collating. Therefore, even among a large number of containers 3 that are stacked and stacked in multiple stages or stored in a storage area, history management is performed as to where the container 3 having specific container information is located. It will be.

Further, the data processing unit 55 has a function of transferring the acquired container information and the above-described history management information of the container 3 to the data management unit 102 of the management control unit 100. In other words, the history management of the container 3
It is similarly managed by the management control unit 100 that manages the operating status of the container handling machine and the operating status of the AGV 5 (see FIG. 4) or trailer. In this case, for example, moving the AGV 5 or the trailer to a predetermined storage position of the container 3, or instructing the operation of the container handling machine such as the transfer crane 7 related to the state of the cargo handling work. Will also be possible.

Further, the data processing section 55 has information inputted by the operator through the input means 52 and the operation control section 5.
4 and the information from the management control unit 100, and also has a function of transferring these information to the data writing means 57 and writing them as container information in the ID tag 3b.

Taking the written container information as an example, information such as where the container 3 to be unloaded is stored in the container terminal, information that confirms that the container 3 has been loaded at a planned place,
It is history information about what kind of cargo handling work was done,
It is written according to each container 3. Thereby, for example, at the moment when the container 3 to be unloaded is held by the spreader 45, it is written where the container 3 is stored. Then, the AGV 5 or the trailer, which is scheduled to carry the container 3, is called via the management control unit 100, or the container information of the container 3 is passed to the transfer crane 7 that loads in the storage area. Become.

Further, in the cargo handling work of the container 3 described above, the position where the specific container 3 is stored in the container terminal is stored by the data processing unit 55 as positional information of the location or operation history data of the moving route. I explained that. These pieces of information are output from the data processing unit 55 to the operation control unit 54, so that the operator does not perform the operation operation from the operation operation unit 51.
The spreader 4 is automatically installed at the position where the predetermined container 3 is located.
5 can be moved. That is, in order to move the spreader 45 to the target container 3,
The operation control unit 54 operates the drive units 58 based on the obtained location information of the container 3 or the operation history data of the travel route.
The operation command will be output to.

It is desirable to apply the above operation control to the transfer crane 7 that loads the containers 3 in the storage area and then hoists the same containers 3 again to load the AGV or the trailer.

As a function added to the operation control section 54, the operation control section 54 has a function of limiting the hoisting or lowering speed of the winch 47 based on the container information obtained by the data reading means 56. is doing.

More specifically, the container information such as the weight of the container obtained from the ID tag reader / writer 45b or the weight of the load stored in the container, the type of the load stored in the container 3, and the like is used for data processing. The operation speed of the winch 43 is limited by being obtained by the operation control unit 54 after being processed by the unit 55. For example,
If the weight of the container 3 to be lifted by the spreader 45 is too large, the operation control unit 54 limits the operation of the winch 43 without prompting the operator, and prompts protection of the winch.

When the container 3 is stopped by being unwound, an excessive load is applied to the winch 43 or a brake provided on the winch 43 depending on the weight of the container 3.
In No. 4, the load is reduced by limiting the winding speed in advance. Further, the operation control unit 54 controls the speed of hoisting and lowering of the winch 43 in an appropriate state according to the weight of the container 3, the type of load, and the like. Then,
Even if the load is not subjected to a large acceleration and thus requires careful handling, it is possible to carry out cargo handling commensurate with it.

The container crane 4 and the container management system according to this embodiment described above have the following effects. An operator of a container handling machine such as the container crane 4 or an operator does not need to confirm the container number when carrying out and loading each container 3, which facilitates cargo handling and improves cargo handling efficiency. It is possible to improve. Further, since the confirmation work is not required, the number of workers involved in the confirmation work can be reduced.

Further, the location of the container 3 can be managed as a history, such as where the container 3 was loaded on the container ship 2, and at what position in the container terminal the container 3 was stored. At the same time, by writing the container information in the ID tag 3b,
The history of use of the container 3 can be managed.

Further, since the container 3 can be automatically moved to a target position or can be automatically moved to receive the container 3, it is possible to reduce the labor in the driving operation of the operator. That is, it is possible to automate the container crane 4.

Further, the operation of the winches 47, (73) can be restricted according to the weight of the container 3,
The winches 47 and (73) are protected, and the labor of the operator in the cargo handling work can be reduced.

In the container terminal, the container 3
Since the information on the container 3 is collectively managed, the container 3 can be smoothly moved in the container terminal, and a container terminal that can efficiently process the container 3 can be realized.

The above-described effects can be obtained in all of the container handling machines including the spreaders 45 and 75, which are suspension devices for containers, such as the transfer crane 7 which is a container handling machine and the transfer machine. Is.

The container handling machine and container management system according to the present embodiment described above are not limited to this, and for example, the configuration described below may be used.

The ID tag 3b has been described as a writable magnetic type, but a bar code or the like may be used. That is, the container information becomes information with a fixed value, and the cargo handling of the container 3 is performed based on this. In this case, since it is limited to reading the container information from the ID tag 3b, the ID tag readers / writers 45b and 75b provided in the spreaders 45 and 75 are configured to have read-only ID tag readers.
