On the other hand, in the case of NO in S55, that is, when the load is not loaded in the designated position, the control unit 16 blinks the floor LED / spotlight 20 to warn that the designated position is incorrect (S58). ). Then, when the load position (loading position) of the load is adjusted by the operator, the control unit 16 detects that the load position has been changed based on the outputs of the load sensors 25A to 25D (S59). , Return to the process of S54.

In S19 and S37, when there is no next package, that is, when all the packages have been loaded, the control unit 16 causes the display unit or the display unit 15 of the mobile communication terminal 28 to display a display indicating the end of loading. You may. Further, the control unit 16 may recognize the end of loading when the loading end button of the loading position indicating device 1 is pressed, or detects that the vehicle 41 has started traveling and ends the loading. You may recognize it.

As shown in FIG. 7, when the loading instruction control device 19 instructs the loading position of each load according to the order shown in the load instruction information, and the first load is not loaded at the correct load position. Is issued a warning and indicates the loading position of the next load when it is loaded in the correct loading position. Therefore, each load can be reliably loaded at an appropriate loading position.

In S17, S35, and S55, the control unit 16 determines whether or not the cargo has been loaded at the designated position, and in addition, the cargo is instructed in S13 based on the registered cargo information (weight). By further determining whether or not the cargo has been loaded, the cargo can be loaded in the correct position more reliably.

FIG. 8 is a flowchart showing an example of a redelivery operation in the loading position indicating device 1. Redelivery may occur, such as when the vehicle 41 arrives at the delivery destination but the luggage cannot be delivered due to the absence. In this case, the loading position indicating device 1 re-searches the delivery route and recalculates the loading position of the package to be redelivered. The process of FIG. 8 is executed in cooperation with the control unit 16 of the electronic control device 10 and the loading instruction control device 19.

When the control unit 16 detects the occurrence of redelivery (S61) by receiving, for example, a button operation by an operator or an instruction from the office, the control unit 16 researches the delivery route of the package (S62). Further, the control unit 16 loads the cargo to be redelivered based on the unloading information, the delivery order, the cargo information, and the current status of the cargo bed 42 (the position of the center of gravity of the cargo loaded on the cargo bed 42). Calculate the position. After that, this loading position is instructed by the loading instruction control device 19. Each process of S63 to S72 of FIG. 8 is the same as each process of S12 to S21 of FIG. Each process of S81 to S89 of FIG. 8 is the same as each process of S31 to S39 of FIG. Each process of S91 to S98 in FIG. 8 is the same as each process of S52 to S59 in FIG.

FIG. 8 shows an operation example when redelivery occurs. For example, even when the office gives an instruction to add a package, an appropriate loading position is calculated for the added package. Instructed. In this way, when a redelivery occurs or an instruction to add a package is given, the loading position indicating device 1 calculates a new delivery route and loading instruction information. Therefore, even if the original transportation schedule is changed, the cargo to be redelivered or added can be loaded at an appropriate position according to the unloading direction at the delivery destination. It is possible to improve the efficiency of work. The electronic control device 10 may obtain instructions (redelivery, addition of luggage) from the office by connecting the setting personal computer 27 to the electronic control device 10, or may be connected to the mobile communication terminal 28 by wide area communication. The transmitted instruction may be acquired via the wireless communication unit 24.

Further, the control unit 16 can prevent the load from collapsing due to the inclination of the vehicle 41 by detecting the load balance of the loading platform 42 while the vehicle 41 is traveling. That is, the control unit 16 calculates the position of the center of gravity of the load loaded on the loading platform 42 based on the outputs of the load sensors 25A to 25D and the outputs of the tilt sensors 26A to 26C while the vehicle 41 is traveling. If the calculated center of gravity position is not within the predetermined range, the control unit 16 generates a warning signal, outputs an alarm from the alarm output units 14 and 22, and causes the driver (worker) to collapse / load. It is possible to grasp the possibility of deviation. For example, if the load on the loading platform 42 is clearly out of balance and it is dangerous if the loading position is not changed, an alarm is issued and the operator can immediately grasp the danger.

When the warning signal is generated, the control unit 16 recalculates the loading instruction information so that the position of the center of gravity during traveling is within the specified range. For example, the control unit 16 changes the position of the easily movable luggage among the luggage loaded on the loading platform 42 based on the information such as the luggage information, the delivery order, and the position of the center of gravity, and the position of the center of gravity is inside the loading platform 42. The loading instruction information is calculated so as to approach the center and the lower side in the vehicle width direction in the space. Similar to the processing of S63 to S89 of FIG. 8, the loading instruction device 1 instructs the display unit or the display unit 15 of the mobile communication terminal 28 to indicate the luggage to be repositioned and the new loading position, and the loading instruction device 1 indicates the luggage to be repositioned and the new loading position. To load. By attaching an IC tag to the luggage, it is possible to identify the luggage to be repositioned and indicate a new loading position of the luggage by the floor LED / spotlight 20.

In this way, when the load balance is detected and there is a possibility that the load may collapse, the safe operation can be continued even if the vehicle 41 is tilted by changing the load position of the load.

As described above, according to the loading position indicating device 1 of the present embodiment, the loading position of each package is calculated by adding the unloading information to the delivery information, and the operator is instructed to do so at the delivery destination. Each load can be loaded at an appropriate position according to the unloading direction of the load. In addition, when the first luggage (first luggage) is loaded at the correct loading position, the loading position of the next luggage (second luggage) is instructed, so that the luggage can be reliably loaded at the appropriate loading position. .. Therefore, the efficiency of unloading work can be improved. Therefore, the time for unloading work is shortened, and the burden on the operator (driver) can be reduced. Further, since the loading position of each luggage is determined in consideration of the luggage information, the loading balance can be optimized so that the weight of the luggage is not biased, and the vehicle can be stably driven (safe driving).

The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, and the like. In addition, the material, shape, size, numerical value, form, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved. For example, in the above-described embodiment, the load position indicating device 1 includes the tilt sensors 26A to 26C, but the tilt sensors 26A to 26C are not indispensable, and the load balance may be detected only from the load sensors 25A to 25D. ..

Further, in the above-described embodiment, the example in which the loading position indicating device 1 (electronic control device 10) is mounted on the vehicle 41 is shown, but at least the calculation of the loading instruction information, the instruction of the loading position, and the loading position are correct. The configuration related to the determination may be provided in the office PC or other communication terminal. Further, in the case of redelivery or the like, the re-search of the delivery route is performed not by the electronic control device 10 but by the office PC, the mobile communication terminal 28 or the like, and the information of the re-searched delivery route is transmitted to the loading position indicating device 1 (electronic control). It may be sent to the device 10).
