Description

The present invention relates to a freight car container loading position management system and a transportation object loading position management system that can easily manage the loading position of a container loaded on a freight car.

When a freight train is used to transport a container, work such as loading and unloading the container on a freight car using a forklift is performed (see Patent Document 1). In such loading work, the loading position of the container in each freight car is managed for loading and unloading work at the arrival station. Conventionally, the management of the loading position has been performed by the person in charge visually confirming the container and its loading position in the station yard and manually creating a list thereof.

Japanese Unexamined Patent Publication No. 11-20951

However, in creating such a list manually, the work load becomes heavy and errors are likely to occur.

By the way, a freight car for loading containers includes a bogie body that extends in the direction of the railroad track and can load a plurality of containers, and a step provided on one end side of the bogie body in the extension direction. Loading numbers are attached to the loading positions of multiple containers on the dolly body. The loading numbers may be assigned in ascending order as they move away from the step in the width direction of the dolly body, and in descending order as they move away from the step in the width direction of the dolly body. In other words, the loading number is inverted in the traveling direction with respect to the width direction on the other side of the trolley body in the width direction.

Therefore, for example, when five containers are loaded on the dolly body and the loading numbers are assigned from "1" to "5", the position closest to the step is "1" in the width direction of the dolly body, which is the closest. The distant position is set to "5", and each loading position is sequentially assigned a loading number. Further, in the width direction of the bogie body, the position closest to the step is set to "5" and the farthest position is set to "1", and each loading position is sequentially assigned a loading number.

In addition, there are both routes that extend in a ring shape and routes that extend radially in the routes on which freight cars travel. For this reason, in the formation of a plurality of freight cars, a state in which the step is located in front of the traveling direction and a state in which the step is located in the rear in the traveling direction are often mixed. Even if they are mixed in this way, by assigning loading numbers that are reversed in the width direction of the bogie body as described above, the loading numbers in the width direction of all freight cars are arranged (increase / decrease direction). ) Is unified, and the loading number arrangement direction is also unified in the width direction and the other side.

Here, in order to reduce the burden of managing the loading position of the container, the present inventor detects the loading number attached to the bogie body when loading the container on the freight car with a forklift and automates the list creation. investigated. However, in a freight car, containers are loaded from both one and the other in the width direction of the bogie body. Therefore, for example, even at the same loading position, the loading number is "1" on one side in the width direction and the loading number is "1" on the other side in the width direction. 5 ”, and the loading number could not be used. Therefore, the present inventor has further studied and invented a system capable of managing the loading position of the container while detecting the loading number attached to the trolley body, as will be described later.

Furthermore, the present inventor has also invented a system capable of managing the loading position of a transportation object on a vehicle or a ship including a truck chassis, as well as a system capable of managing the loading position of a container with respect to a freight car.

The communication unit 64 is composed of an external communication interface that communicates with a server as an external device described later. The communication unit 64 has a function of transmitting the detection results of the detection units 61 to 63 to the server.

Subsequently, the configuration of the container loading position management system for the freight car according to the embodiment will be described. FIG. 2 is a diagram showing an overall configuration of a container loading position management system for freight cars according to the embodiment. Note that FIG. 2 shows only the configurations related to the present invention, and the other configurations are omitted.

As shown in FIG. 2, the freight car container loading position management system 10 (hereinafter referred to as “management system”) includes an identification information detection unit 61, a number detection unit 62, and a loading direction detection provided in the forklift 6 as described above. A unit 63 and a communication unit 64 are provided. Further, the management system 10 includes a setting unit 21 provided in the server 20.

The server 20 includes a communication unit 22 that receives the detection results of the detection units 61 to 63 transmitted from the communication unit 64 of the forklift 6. In addition, the server 20 includes an operation management system 23 that stores and manages operation information of each freight train 3 under control. The operation management system 23 includes the above-mentioned setting unit 21 and a storage unit 24 for storing operation information of each freight train 3 as one of its functions.

The information stored in the storage unit 24 includes the train number of each freight train 3 under control. In general, the column number is an up train when the number is even, and a down train when the number is odd. By acquiring the line number, it is possible to determine whether the traveling direction is from the up direction to the down direction.

As other information stored in the storage unit 24, the traveling direction of the freight car 8, the loading direction of the container 4 by the forklift 6, and the loading on the front side of the freight car 8 as viewed from the forklift 6 for loading the container 4 in the loading direction. There is a relationship with the direction in which the numbers are lined up. In the present embodiment, when the loading direction is north, the traveling direction in the ascending direction is the same as the direction in which the loading numbers on the front side of the freight car 8 when viewed from the forklift 6, that is, on the south side of the freight car 8 are arranged in descending order. .. Further, when the loading direction is the north direction, the traveling direction in the downward direction and the direction in which the loading numbers on the south side of the freight car 8 are arranged in ascending order are the same. On the other hand, when the loading direction is the south direction, the traveling direction in the downward direction and the traveling direction in which the loading numbers on the front side of the freight car 8 as viewed from the forklift 6, that is, the north side of the freight car 8 are arranged in descending order are the same, and the traveling is in the upward direction. The direction and the direction in which the loading numbers on the north side of the freight car 8 are arranged in ascending order are the same. The relationship between the loading direction, the traveling direction, and the direction in which the loading numbers are lined up is stored in the storage unit 24 as, for example, a table shown in Table 1 below.

The setting unit 21 outputs the detection results of each of the detection units 61 to 63 from the communication unit 22 of the server 20 and acquires the detection results. Further, the setting unit 21 reads out the column number of the freight train 3 stored in the storage unit 24 and acquires the traveling direction of the freight train 3 including the freight car 8. Specifically, the setting unit 21 performs a process in which the traveling direction is set to the up direction when the row number of the read freight train 3 is even, and the traveling direction is set to the down direction when the row number is odd.

The setting unit 21 obtains the direction in which the loading numbers on the front side of the freight car 8 are lined up when viewed from the forklift 6 for loading the container 4 in the loading direction. Specifically, the setting unit 21 reads out the table of Table 1 stored in the storage unit 24, and loads from the loading direction detected by the loading direction detecting unit 63 and the traveling direction acquired from the column number of the freight train 3. The process of acquiring the direction in which the numbers are lined up is performed.

The setting unit 21 compares the direction in which the loading numbers of the acquired freight car 8 are lined up with the traveling direction. Then, when the direction in which the loading numbers are arranged in descending order and the traveling direction match, the setting unit 21 performs a process of maintaining the loading number detected by the number detecting unit 62. That is, the loading number on the south side of the freight car 8 traveling in the upward direction and the loading number on the north side of the freight car 8 traveling in the downward direction are maintained. On the other hand, when the directions in which the loading numbers are arranged in ascending order and the traveling direction match (see Table 1), the setting unit 21 performs a process of reversing the loading numbers detected by the number detecting unit 62 in the traveling direction. Therefore, the loading number on the north side of the freight car 8 traveling in the upward direction and the loading number on the south side of the freight car 8 traveling in the downward direction are "5" to "1", "4" to "2", and "2" to "2". "4", "1" is converted to "5", and "3" is left as it is.

The setting unit 21 associates the loading number that has been maintained and inverted as described above with the identification information of the container 4 detected by the identification information detection unit 61, and stores it in the storage unit 24.

According to such an embodiment, by detecting and associating the loading number of the container 4 in the trolley main body 8a with the identification information of the container 4, the management of the loading position of the container 4 is automatically performed easily and in a short time. Can be done. In such management, the loading number associated with the identification information of the container 4 is shown in FIG. 3 according to the traveling direction of the freight car 8 (freight train 3). In FIG. 3, even if the freight cars 8 inverted so as to change the position of step 8b are mixed, they are loaded from the front to the rear in the traveling direction of the freight cars 8 on both sides (north side and south side) in the width direction of the freight cars 8. It can be managed so that the numbers increase sequentially.

As a result, even if the forklift 6 is used to load the trolley body 8a from both the north side and the south side of the track 2 on both sides in the width direction, the loading number associated with the identification information of the container 4 can be unified. As a result, the loading position of the container 4 can be accurately and quickly grasped based on the loading number stored in the storage unit 24, and the management burden and the loading / unloading work burden can be reduced.

The present invention is not limited to the above embodiment, and can be modified in various ways. In the above embodiment, the size, shape, direction, etc. shown in the attached drawings are not limited to this, and can be appropriately changed within the range in which the effects of the present invention are exhibited. In addition, it can be appropriately modified and implemented as long as it does not deviate from the scope of the object of the present invention.

For example, the identification information detection unit 61 and the number detection unit 62 are not limited to the configuration for detecting the ID tag. The detection target of the identification information detection unit 61 and the number detection unit 62 can be changed in various ways, such as an image-recognizable object such as a barcode or an infrared-recognizable object. The configurations of the detection units 61 and 62 are also changed as appropriate.

Further, the loading direction detection unit 63 may be changed by using a geomagnetic sensor, a compass, or the like as long as it can function in the same manner as in the above embodiment.

Further, as an example, the case where the loading number is set to "1" to "5" has been described, but it is not particularly limited, and the extension direction of the trolley body 8a is not particularly limited, and the trolley body 8a can be extended by using alphabets, symbols, or a combination of these and numbers. It may be a number arranged in order. Further, the ascending order and the descending order of the loading numbers may be in a relationship in which the order is relatively reversed, and for example, the order of increasing or decreasing the numbers may be opposite to that of the above embodiment.

Further, as long as the cargo handling machine can load the container 4 on the freight car 8, various changes can be made such as using a transport vehicle other than a forklift, an electric lift, or a crane.

Further, the number of containers 4 loaded on one bogie body 8a is not limited to five, and may be increased or decreased as appropriate, and the size and shape of each container 4 may be the same or different. Good.

Further, in the above embodiment, the case of managing the loading position of the container 4 loaded on the freight car 8 of the freight train 3 has been described, but the present invention is not limited to this. For example, when managing the loading position of a transportation object such as a container loaded on a vehicle such as a truck chassis, or when managing the loading position of a transportation object such as a steel rack loaded on a ship, the above implementation is also performed. The loading position can be managed in the same manner as in the above form.

In these cases, a vehicle or ship traveling on a predetermined route is applied instead of the freight car 8 traveling on the railroad track in the above embodiment, and the vehicle or ship is the bogie main body as in the freight car 8 of the above embodiment. A loading number shall be attached to the loading position. Also in the management of the loading position of the object to be transported in such a vehicle or ship, the loading number can be sequentially increased from the front to the rear in the traveling direction, and the loading number associated with the identification information of the object to be transported can be unified.

The present invention relates to a loading position management system for managing the loading position of a container to be loaded on a freight car, a vehicle, or an object to be transported loaded on a ship.
