DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0013]
FIG. 1 shows a container handling vehicle equipped with a container.
[0014]
This container handling vehicle is provided with a loading / unloading device 2 for loading / unloading the container C on / from the vehicle body 1 and discharging the load in the container C.
[0015]
The cargo handling device 2 includes an outer arm 21 that is horizontally disposed in a state in which the container C is mounted, and a telescopic arm 22 that is formed in an L shape as a whole, including a vertical portion 22b that is vertically disposed in the same state. It has.
[0016]
The outer arm 21 is rotatably supported at its rear end portion via a dump frame 2a (see FIG. 5) that is rotatably supported at the rear portion of the vehicle body 1.
[0017]
The telescopic arm 22 is formed in a substantially L shape by a horizontal portion 22a inserted into the outer arm 21 and a vertical portion 22b erected from the front end portion of the horizontal portion 22a. The horizontal portion 22a is shown in the figure. The outer arm 21 can be extended and contracted in the longitudinal direction by a non-extending cylinder.
[0018]
The vertical portion 22b is provided with a hook 23 that is detachably engageable with an engagement pin C1 provided on the container C at the tip thereof.
[0019]
Further, a hoisting cylinder 24 (see FIGS. 3 to 5) is connected between the outer arm 21 and the vehicle body 1, and the cargo handling device 2 is centered on the rear end portion by the elongating and retracting operation of the hoisting cylinder 24. And is configured to be rotatable in the front-rear direction.
[0020]
As the container C, an open type whose upper surface is opened or a sealed type whose upper surface is also closed is used, and the rear wall can be opened and closed so that the load can be discharged. In addition, the engaging pin C1 is provided at the upper part of the front wall, the support leg C2 is provided at the bottom front part, and the support roller C3 is provided at the bottom rear part.
[0021]
Furthermore, a roller 11 for smoothly loading and unloading the container C between the vehicle body 1 and the ground is provided at the rear end portion of the vehicle body 1.
[0022]
Then, when the container C is unloaded by the container handling vehicle, first, in a state where the container is mounted as shown in FIG. 1, the horizontal portion 22a of the extendable arm 22 is moved from the outer arm 21 by the extendable cylinder as shown in FIG. The container C on the vehicle body 1 is slid backward by a predetermined length. After that, as shown in FIG. 3, the container C is tilted by rotating the outer arm 21 together with the telescopic arm 22 by the hoisting cylinder 24. As a result, the container C can be lowered from the top of the vehicle body 1 to the ground as shown in FIG. Further, the ground container C is loaded onto the vehicle body 1 by the reverse operation to that described above.
[0023]
On the other hand, when discharging the load loaded in the container C, the outer arm 21 and the dump frame 2a are fixed integrally by a lashing device (not shown) with the container C loaded on the vehicle body 1. By tying and retracting the telescopic arm 22 with respect to the outer arm 21, the cargo handling device 2 is pivoted upward as shown in FIG. Discharge.
[0024]
By the way, this container handling vehicle is provided with a container loading control device which is the main part of the present invention for controlling the operation of the cargo handling device 2.
[0025]
This container loading control device enables loading of only an appropriate container C corresponding to a container loading vehicle equipped with the loading device 2 and makes improper loading of the container C impossible.
[0026]
Specifically, as shown in FIG. 6, an ID tag 3 in which identification data is written in advance in a container C is provided, and a reading device 4 (for reading the identification data of the ID tag 3 on the container cargo handling vehicle side including the cargo handling device 2). 8).
[0027]
The ID tag 3 is provided on the front surface in the vicinity of the engagement pin C1 of the container C. In the ID tag 3, as identification data, as shown in FIG. 7A, a user number specifying a user, a container number specifying a container, and a personal identification number are written. For example, 16 bytes ( 128 bits) is used.
[0028]
On the other hand, the reading device 4 is configured to read the identification data of the ID tag 3 through the antenna unit 41.
[0029]
The antenna portion 41 is provided, for example, at the tip of the vertical portion 22b of the telescopic arm 22 so as to be adjacent to the hook portion 23, and the hook portion 23 is engaged with the engagement pin C1 in order to load the container C into the vehicle. Both are arranged so as to confront the ID tag when trying to engage with the ID tag.
[0030]
Then, the identification data of the container C read by the reading device 4 is input to the control unit (control device) 5 shown in FIG.
[0031]
The control unit 5 determines whether the container C is appropriate or inappropriate based on the identification data from the reading device 4, and controls the loading operation of the cargo handling device 2 based on the determination result.
[0032]
Specifically, the identification data of each container C is stored in the control unit 5 by the registration device 6, and the registered registration data is compared with the identification data read through the reading device 4.
[0033]
As a result, if both data match, it is determined that the container C is proper, and the container handling device 2 can be operated via the drive circuit 7 to perform the loading operation as described above. Load C into the vehicle.
[0034]
Further, if the two data do not match or the identification data of the container C cannot be read by the reading device 4, it is determined that the container C is inappropriate, and the operation from the operation unit 8 is performed by the restriction circuit 51 serving as restriction means. Regardless, the operation of the cargo handling device 2 is disabled so that the container C cannot be loaded on the vehicle.
[0035]
That is, when the container C is loaded on the vehicle, first, as shown in FIG. 6, it is necessary to rotate the cargo handling device 2 backward to engage the hook 23 with the engagement pin C1 of the container C. Before the two are engaged, the antenna unit 41 faces the ID tag 3 in close proximity, thereby reading the identification data of the ID tag 3 and determining the suitability of the container C as described above.
[0036]
The registration device 6 is detachably attached to the control unit 5, for example, and is connected to the control unit 5 as necessary to register the identification data of the container C.
[0037]
By controlling the loading operation of the container C by the cargo handling device 2 based on the identification data written in the ID tag 3 of the container C in this way, loading of an inappropriate container C with a different user number or the like onto the vehicle is performed. It is possible to reliably prevent loading, and it is possible to prevent damage or failure of the cargo handling device 2 or the vehicle due to such unreasonable loading of the inappropriate container C. Moreover, the ID tag 3 may be disposed in the container C, and can be easily applied to existing containers C and container handling vehicles.
[0038]
When unloading the container C, since only the proper container C is loaded by the loading control device, it is not necessary to apply the above-described regulation.
[0039]
When the loading of the container C is restricted by the restriction circuit 51 as described above, the operation of the cargo handling device 2 becomes impossible and the next container C cannot be loaded as it is, so the restriction is made as follows. I try to release it.
[0040]
That is, the radio wave from the antenna unit 41 is weakened, and the control of the cargo handling device 2 by the regulation circuit 51 is made effective in the control unit 5 within a predetermined range in which the radio wave reaches the ID tag 3. Accordingly, when the container C is inappropriate and the operation of the cargo handling device 2 is restricted, the vehicle is moved to a place where the radio wave of the antenna unit 41 does not reach the ID tag 3. As a result, the restriction by the restriction circuit 51 is released and the cargo handling device 2 can be operated. Therefore, the cargo handling device 2 can be stored on the vehicle body 1 side, and the next container C can be loaded.
[0041]
A means for directly recognizing the identification data of the ID tag 3 is provided not on the cargo handling device 2 but on the vehicle body 1 side, and when the vehicle is stopped for loading the container C, the identification data on the ID tag 3 is read to load the cargo handling device 2. You may make it apply operation regulation to. As a result, when the container C is inappropriate, the cargo handling device 2 becomes inoperable in the retracted state, and the loading operation of the cargo handling device 2 becomes possible only when the appropriate container C is loaded. When the means for directly recognizing the ID tag 3 is provided on the vehicle body 1 side as described above, the distance between the vehicle body 1 and the container C is increased when the container C is loaded. In order to read the ID tag 3 reliably, it is necessary to give directivity to the above means.
[0042]
In addition to the user number and the container number, the ID tag 3 can also be written with a type number for specifying the type of the container C as shown in FIG. 7B. The type such as the size of the container C can be recognized.
[0043]
That is, when the container C is loaded on the vehicle, the control unit 5 controls the amount of expansion / contraction of the expansion / contraction arm 22 relative to the outer arm 21 according to the size (length) of the container C so that the container C can be Each container C can be stably arranged at an appropriate position of the vehicle by controlling the amount of expansion / contraction of the telescopic arm 22 based on the type number.
[0044]
Further, even if the user numbers match, for example, the container C may be large and cannot be loaded into the cargo handling vehicle. In this case, the operation of the cargo handling device 2 is restricted and the container C is not loaded erroneously. It can also be done.
[0045]
Furthermore, the identification data is written to the ID tag 3 by acquiring the identification data from the container management organization or the like through the Internet, for example, and writing it in the ID tag 3 by the writing device based on the acquired identification data. Alternatively, a writing device may be provided in the vehicle so that writing is performed on the ID tag 3 disposed in the container C.
[0046]
At this time, the personal identification number written in the ID tag 3 is inserted when the identification data is written into the ID tag 3 by the writing device, and the identification data can be written when the personal identification number matches. Thus, falsification of identification data can be prevented.
[0047]
In the present embodiment, the cargo handling device 2 in which the telescopic arm 22 is telescopically operated with respect to the outer arm 21 has been described. However, the loading control device of the present invention has the outer arm 21 and the telescopic arm 22 that are not telescopic. It can also be applied to a cargo handling device of a type in which and are integrally provided.
[0048]
【The invention's effect】
As described above, according to the container loading control device in container handling vehicle of the present invention, it arranged a previously written identification data in the container, thereby enabling loading the cargo apparatus to the container based on the identification data In addition, when the identification data is inappropriate, it is possible to reliably prevent the loading of an inappropriate container with a different user number into the vehicle by making it impossible to load the container by the regulating means. In addition, it is possible to prevent damage or failure of the cargo handling apparatus or vehicle due to such unreasonable loading of an inappropriate container. Moreover, it can be easily applied to existing containers and container handling vehicles.
