Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a load position optimizing apparatus and a load position determining method for automatically determining a load position when size information and weight information of a load to be loaded on transportation equipment are given.

[0002]

2. Description of the Related Art Generally, when a heavy load is loaded on a transportation device, a transport planner performs a loading simulation in advance to determine a loading position at which the load can be safely transported with maximum efficiency. This simulation has been carried out manually by the transport planner, but when the number of loads is large, the calculation of the center of gravity position for the simulation is complicated, so that the entire load is loaded on a personal computer or a general-purpose computer. A loading position optimizing device has been proposed in which the position of the center of gravity is calculated. When the user specifies the loading position, the size, and the weight of the loaded object, the initial loading position optimizing device displays a graphic 1 showing a transportation vehicle and a graphic 2 showing a loaded object on the display screen as shown in FIG. Is displayed, the position of the center of gravity of the entire load is calculated from the given position and weight of the load, and the position of the center of gravity is displayed or printed. The user determines whether or not the loading position is optimal by looking at the position of the center of gravity visually output. When the loading position is not optimal, the user uses the pointing device to change the position of the loading object by instructing the new position of the loading object graphic displayed on the display screen, and the loading position optimizing device is operated. The calculation of the position of the center of gravity was executed again. By repeating such processing by trial and error, the loading position of the loaded object at the time when the optimal center of gravity position is obtained is finally determined as the optimal loading position.

In order to further improve the user's instruction operation, a load position optimizing device for automatically determining the load position of the load has been proposed. In this device, the user collectively gives information about only the size and weight as the information about the load. The loading position optimization device sets a virtual space simulating a loading platform of a vehicle on a computer. The computer temporarily arranges an arbitrary load 2 at the initial position A in FIG. 3, and updates the empty area of the space (two-dimensional space in the example of FIG. 3) after the load is arranged. Based on the given size information, the computer temporarily arranges the loads in a line in the X direction of FIG. 3 and updates the empty area. When the load reaches the end of the loading platform, the leading position of the empty area is changed to the leading position of the next row. Hereinafter, the above-described processing is repeated until all the given loads are temporarily placed on the loading platform. In this way, when the first temporary placement of all the loads is completed, the overall center-of-gravity position in the placement is calculated, and the calculation result and the placement of the loads are stored in the memory in the device. The combination of the loading order of the loaded items is determined by a permutation combination regarding the number of loaded items, such as two combinations of a → b and b → a for two loaded items a and b. Therefore, the stacking position optimizing device performs the above-described temporary placement processing for all combinations of the loading orders to obtain the position of the center of gravity in the placement. The loading position optimization device calculates the distance between each gravity center position thus obtained and the gravity center position of the vehicle itself, and the provisional arrangement having the gravity center position with the shortest distance, in other words, the gravity center position of the vehicle, The closest center-of-gravity position of the temporary arrangement is determined as the optimum loading position.

[0004]

In the above-mentioned loading position optimizing device, since the loading position is automatically determined, the instruction operation by the user is simplified, but the loading position optimizing device is
The stackable position of the load is searched, and the overall center-of-gravity position is calculated using each of the stackable positions. For this reason, there has been a problem that the calculation processing time, in particular, the search time of the loadable position and the calculation time of the center of gravity position of the first plurality of loaded objects having large empty areas become long.

Therefore, an object of the present invention is to shorten the processing time by reducing the calculation amount of the position of the center of gravity, and
An object of the present invention is to provide a loading position optimizing device and a loading position determining method thereof that do not impair safety during freight transportation.

When the specific order is exceeded, the computer further comprises another position determining means for determining an optimum loading position from the empty area in the virtual space at that time.

According to a fifth aspect of the present invention, a virtual space simulating the loading place of the transportation equipment is set on a computer in the loading position optimizing device, and the optimal loading position of the load is set in the empty space of the virtual space. The loading position determining method of the loading position optimizing apparatus determines the loading position of a plurality of loads by updating the empty area every time the computer determines the loading optimum position. A plurality of types of loadable areas corresponding to the total weight are registered in the computer, and the computer calculates the total weight of the load to be loaded, and the total load obtained as a result of the calculation is calculated. The stackable area corresponding to the weight is selected from the registered stackable areas, and the stacking position of the stacked object is determined in the empty area of the selected stackable area. .

According to a sixth aspect of the present invention, in addition to the fifth aspect of the present invention, a plurality of types of loadable areas registered in the computer have a low load total weight when the loadable area is high. The loadable area is included, and the center of gravity of only the transportation device is defined to be included in all the loadable areas.

According to a seventh aspect of the present invention, in addition to the sixth aspect of the invention, when the computer determines the loading position of the n-th (n is a positive integer) load item, the computer reads the first load item from the first load item. The total load weight up to the n-th load is calculated, the loadable area corresponding to the total load weight is selected from a plurality of types of loadable areas registered in the computer, and the selected loadable area is selected. It is characterized in that the position farthest from the center of gravity position is determined as the loading position of the loaded object in the empty region at that point in time.

[0016]

According to the first and third aspects of the present invention, the loading target range of the load is not set to the entire loading platform of the transportation equipment as in the conventional case, but a plurality of different loadable ranges are prepared to correspond to the loading order of the load. Assign a loadable range, and within this loadable range,
Determine the loading range of the load. Therefore, the position search range of the computer is narrowed, and the time for the stacking position determination process is shortened. In addition, by determining the loadable range in advance in consideration of the safety of transportation equipment, it is not necessary to calculate the gravity center position of the load as in the conventional case, and the load position determination processing time is further shortened. To be done.

According to the second and fourth aspects of the present invention, by limiting the stackable area to be allocated in the stacking order, for example, two, this contributes to shortening the stacking position determination time, and the stacking load It is possible to load a large-sized load between these two without restricting the shape. By applying the conventional method to the third and subsequent loads, it is possible to load a large number of loads without gaps.

According to the fifth and eighth aspects of the present invention, the calculation of the position of the center of gravity in the related art is omitted by deciding the selection of a plurality of loadable areas in accordance with the total weight of the load.

According to the sixth and ninth aspects of the present invention, the loadable area when the total load weight is high includes the loadable area when the total load weight is low. Therefore, an additional load is generated after the load position is determined. As well as ensuring the loading range of the load,
It is not necessary to calculate the position of the center of gravity after adding a new load. According to the seventh and tenth aspects of the present invention, when the positions of a plurality of loads are sequentially determined, the stackable area is variably set according to the total weight of the loads loaded so far. Further, the loaded objects in the quickest loading order are loaded from the position farthest from the position of the center of gravity of the transportation equipment in the empty area of the set loadable area. For this reason, since the loaded objects in which the same loadable area is set are loaded toward the position of the center of gravity as the loading order becomes later, the safety of the transportation device is improved.

[0020]

Embodiments of the present invention will now be described in detail with reference to the drawings.

<First Embodiment> A loading position optimizing apparatus to which the inventions of claims 1 to 4 are applied will be described. The system configuration of this loading position optimizing device is shown in FIG. In FIG. 4, the following constituent circuits are commonly connected to the bus.

Central processing unit (CPU) 10: Controls the entire apparatus according to a system program stored in a read only memory (ROM) 20 and determines the placement of the load.

ROM 20: Stores the above system program read and executed by the CPU 10. Since information indicating a plurality of types of stackable ranges (described later) is stored in this memory, the ROM 20 corresponds to the storage means in claim 3.

RAM 30: Temporarily stores data used for calculation by the CPU 10. Information regarding the arrangement of the loaded items is created by expansively storing the information indicating the loaded items in this memory. FIG. 5 shows an example of the configuration of this information storage area (hereinafter referred to as the loading information area). In the loading information area, a number indicating the loading order is also stored as an identification number,
Numerical values indicating the width W and length L of the load corresponding to this number,
Information indicating the weight WT and the loading position is stored. The loading position information is the X and Y coordinates with the reference position of the loading platform as the origin, and the loading range is represented by the coordinates. For example, the stacking information of number 1 indicates that it is located between X1 and X2 in the X-axis coordinate and between Y1 and Y2 in the Y-axis coordinate.

Printer 40: Prints information received from the CPU 10.

Pointing device 50: display device 6
By specifying the position of the display screen of 0 with a cursor mark or the like, the message and the coordinate position displayed on the display screen are input.

Floppy disk storage device (FDD) 9
0: Information is read from and written to the mounted floppy disk.

The load position determining process of the load according to the present invention executed in the load position optimizing apparatus having the computer system 100 will be described below.

When the power is turned on, the processing procedure (program) shown in FIG. 6 is read from the ROM 20 and executed by the CPU 10. This control procedure is actually performed by the CPU 10
Is written in an executable programming language, but is expressed functionally for convenience of explanation. 7 to 10 show detailed procedures of the processing in FIG.

The CPU 10 uses the variable co used in the program.
The value of the unt value and the value of the variable indicating the total weight are initially 0 (zero).
Initialize (S10 of FIG. 6). The variable count is used as a counter that counts the input order of the load information that is input. The user sequentially inputs the loading information, that is, the information indicating the width, the length, and the weight of the loaded object, from the keyboard 70. When one set of loading information is input (S20 in FIG. 6), the CPU 10 adds 1 to the variable count and counts the input order. Since this input order corresponds to the stacking order, the CPU 10 at the time of counting the input order operates as the stacking order identifying means of the invention of claim 3. Further, the weight in the loading information is cumulatively added to the total loaded weight up to now. Further, the count value (1 at this time) is added to the stacking information and the first stacking information is stored in the RAM 30 (see FIG. 5, but the stacking range information is not stored at this point-in FIG. 6). S30).

When the first loading information is input, the variable count stores the numerical value 1, so the CPU 10
The execution procedure of (1) proceeds from S40 to S100, and the placement of the first load is determined. In the present embodiment, the stackable position of each of the first to n-th stacked objects is shown in advance, more specifically, the stackable position in which the stackable area is one-dimensionally represented (claims 1 and 3). Corresponding to the loadable area) is R
It is prepared in the program of the OM20, and except the first load, other loads can be selected from a plurality of positions based on the shape information of the load based on the shape information of the load. There are features. FIG. 7 shows the contents of the first load position determination process in S100. In FIG.
The CPU 10 uses the center position P (see FIG. 1) previously assigned to the first load and the width and length in the first load information to coordinate X1, which indicates the load area of the load.
X2, Y1 and Y2 are calculated (S110 in FIG. 7). An example of this calculation formula is shown.

[0035]

## EQU1 ## X1 = PX-L / 2, X2 = PX + L / 2, Y1 = PY + W / 2, Y2 = PY-W / 2 where PX and PY are coordinate values of the position P given in advance. L is the length of the load and W is the width of the load. The calculated coordinate range indicates not only the loading position of the first load but also another load cannot be loaded, in other words,
It also shows the free space. Therefore, the coordinate range information is stored in the RAM 30 as the position information and empty area information of the load (see FIG. 5—S120 of FIG. 7).

The user inputs the second loading information to the keyboard 7
When input from 0, the execution procedure of the CPU 10 is S1 in FIG.
The sequence proceeds from 00 to S80 to S20, and the CPU 10 receives the input stacking information and updates the value of the variable count to 2 (S20 to S30). As a result, the procedure is S40 → S5.
The process proceeds from 0 to S200, and the processing for determining the loading position for the second loaded object is executed (S200). The detailed procedure of this processing is shown in FIG. This process is a procedure for determining the position of the second load according to the total of the width a of the first load and the width b of the second load. In this embodiment, a plurality of positions Q1 to Q4 are provided at positions facing the first position P with the center of gravity of the vehicle interposed therebetween (see FIG. 1-second).
The loadable range of the second load) is prepared on the ROM 20. This procedure is selected by the CPU 10 so that the loading position of the second load is Q1 to Q of the stackable position.
4 is determined (S215 to S240 in FIG. 8).
Either). Therefore, the CPU 10 at this time operates as the selecting means and the position determining means of the invention of claim 3.
After that, the CPU 10 calculates the coordinate value indicating the second loading range in the same manner as the equation 1, and stores it in the RAM 30 (S250 in FIG. 8). In this way, the loading position for the second loaded item is determined.

When the user instructs the end of the input of the loading information from the keyboard 70, the execution procedure of the CPU 10 proceeds from S200 to S80 to S90 in FIG. 6, and the first and second operations determined so far are performed. The loading position (range information) of the loaded items is read from the RAM 30 by the CPU 10, and a square figure connecting the coordinates indicated by the range information (reference numeral AA1 in FIG. 1).
The layout of the loaded items is printed by the printer 40 in the form of or.

When the user inputs the loading information up to the (n + 1) th, the CPU 10 counts the input order of the loading information.
The position determination process is performed for each of the n-th order and the position determination process determined for each order is executed to determine the position of each load. An example of the position determination process of the third load is shown in FIG. 9 for reference. In this example, the third position is determined by the weights of the first and second loads. If the type of the shape of the load is determined to be one or two, such as an electric wire coil, it is sufficient to prepare a loadable position on the ROM 20 so that the load does not contact each other. Prepare a loadable position that is suitable for loading loads in terms of safety. If the shape of the load is unspecified,
As shown by blocks AA2 and AA3 in FIG. 1, a two-dimensional stackable area is prepared, and a new central position of the stack is set so that it does not come into contact with the stacks installed so far. Find in More specifically, when a new load is placed in the previously prepared position, the load placed so far and the new load come into contact (including the case where a certain interval is provided between the load). C to determine whether or not
When it is executed by the PU 10 and a contact is made, the position of a new load is slightly moved from this position, and the CPU 10 determines whether or not there is a contact at the new position. In this way, the CPU 10 searches the empty area of the stackable area to find a suitable stacking position. In this case, there is an advantage that the search area is limited, the center of gravity is not required to be calculated, as compared with the conventional case in which the entire loading platform of the transportation vehicle is searched for the loading position.

When the (n + 1) th and subsequent loaded objects that exceed the specific order n are input, the loading position is determined in the CPU 10 by using the same method as the conventional one. This processing procedure is shown in FIG. The CPU 10 searches the entire empty area area that does not touch the area indicated by the range information in the RAM 30 (S400 in FIG. 10) and detects a plurality of stackable positions. After that, the CPU 10 executes the overall center of gravity calculation at a plurality of positions (S420 in FIG. 10), and determines the position where the center of gravity is closest to the center of gravity of the vehicle as the position of the load (S440 in FIG. 10). At this time, the CPU 10 operates as the position determining means of the invention of claim 4. Similar to the above, the loading positions of the respective loads determined so far are printed in the form of figures or numerical values in response to the user's instruction to finish (S80 → S90 in FIG. 6). Loaded number is a specific value (n)
If it exceeds, it is difficult to load a load having an unspecified shape so that it does not come into contact with another position at a predetermined position. Therefore, in this embodiment, the position is determined by the conventional method. In this case n
Since the loading position of each load has already been decided, CP
The free area that is the search target of U10 is small, and the processing time does not take much time even if the position determination processing similar to the conventional one is performed.

With respect to the first embodiment, the following form can be implemented.

1) Up to which order (value of n) of the loaded items the predetermined loading position (loadable area) can be determined according to the type and shape of the loaded items. Further, the value of n can be variably set by an instruction from the user's keyboard 70. In this case, a process of storing the value of n input from the keyboard 70 in the RAM 30 is added to S10 of FIG. 6 so that the count value becomes the specified value of n + 1 between S30 and S40. A determination is made as to whether or not a positive determination is obtained, and the execution procedure is shifted to S70. Using such a procedure, when the user specifies n = 1, for example, after the first load is automatically placed at the initial fixed position, the load position is determined by searching for an empty area as in the conventional case. be able to.

2) In this embodiment, an example in which the stacking position is determined every time the stacking information is input has been described, but it goes without saying that a plurality of sets of stacking information may be collectively input in advance. The method of individually inputting the loading information is suitable for inputting from the keyboard 70, and the method of collectively inputting the loading information is to read the loading information stored in a floppy disk or the like to read the CPU 1
Suitable when inputting 0.

3) In the present embodiment, the case in which the stackable area is composed of a plurality of one-dimensional positions and the case of being composed of a two-dimensional flat area have been described. Which one is used depends on the content of the load. It may be appropriately determined according to the situation.

<Second Embodiment> The first embodiment is an example in which the loadable range of a fixed number of loads is fixed, but the loads can be made to correspond to the total weight (cumulative weight) of the loads. A second embodiment in which the loadable range is determined (claims 5 to 1).
(Corresponding to the invention of 0) will be described below. The system configuration of the second embodiment can be made almost the same as that of the first embodiment of FIG. However, since the execution procedure of the CPU 10 is different,
An execution procedure of the CPU 10 in the embodiment is shown in FIG.
A stacking position determination method according to the second embodiment will be described with reference to FIG.

After the power is turned on, the variables used for the calculation are initialized, and then the control procedure of FIG. 11 is executed. The user inputs the loading information of the first load from the keyboard 70. The CPU 10 sets the loading information (weight, shape and dimension) to R
After it is stored in the AM 30, it is added to the accumulated weight (0 in this case) indicated so far by the loading information. next. The CPU 10 obtains the loading ratio of the cumulative weight to the maximum loading weight of the vehicle (S1010 to S1020 in FIG. 11).

In this embodiment, the loadable area until the load ratio reaches 50%, the loadable area up to 75%, the loadable area up to 80% and 100%.
A stackable area reaching up to is prepared in advance in the ROM 20 in the form of numerical information. Therefore, the ROM 20 operates as the storage means of the invention of claim 8. An example of this stackable range is shown in FIG. In FIG. 12, reference numeral 104 indicates the position of the center of gravity of the vehicle. Reference numeral 102 indicates a stackable range having a stacking ratio of 50% or less. Reference numeral 103 indicates a loading ratio of 7
The loadable range is up to 5% and the load ratio is 5
The loadable range 102 up to 0% is included in the loadable area 103 up to a load ratio of 75%. Although the stackable areas up to 80% and 100% are not shown in FIG. 12, the stackable area with the low stacking rate is included in the stackable area with the high stacking rate, which is the same as above.

The CPU 10 determines which of the above-mentioned stackable ranges the stacking ratio obtained in S1020 corresponds to.
When it is determined that the stacking ratio obtained by the calculation is 50% or less, the empty area in the stackable range 102 of FIG. 12 is set as the area of the position search target, and in the empty area of this setting area, The position where the load having the shape and size of the first load information can be loaded is searched. Here, the important point is that the CPU 10 searches for a position in the empty area that is farthest from the center of gravity position 104 (see FIG. 12) of the vehicle, and determines the position obtained by the search as the loading position of the load. It is a point.

For this reason, the CPU 10 determines an empty section from the stackable range set by the numerical value, that is, the closed section area in the two-dimensional space excluding the section in which the load information indicated by the range information stored in the RAM 30 is set. Is calculated by a numerical calculation, and the coordinate position farthest from the barycentric position in the empty section is calculated according to a predetermined calculation formula. As a result,
For example, when the position of reference numeral 107 in FIG. 12 is obtained as the loading position of the first load, the CPU 10 stores the range information indicating this loading position in the RAM 30 (S in FIG. 11).
1060).

The user then inputs the second loading information from the keyboard 70 (S1060 → S10 in FIG. 11).
70 → S1010). In the same manner as described above, the weight indicated by the input load information is accumulated in the total load weight so far. At this time, the CPU 10 operates as the arithmetic means of the invention of claim 8. If the loading ratio determined from the total loaded weight is, for example, between 50% and 75%, the procedure is S1030 → 1.
200, the stackable range corresponding to the stacking ratio of 75% (see the area 103 in FIG. 12) is selectively set as the position search target. The CPU 10 at this time is claim 8.
It operates as the selection means of the invention. The CPU 10 detects a position 106, which is farthest from the center of gravity 104 in the empty area of the stackable area 103 and can be spaced a certain distance from the loaded objects, based on the range information in the RAM 30, RAM for loading range information at this position
It newly registers in 30 (S1060 of FIG. 11). At this time, the CPU 10 operates as the stacking position determining means according to claims 8 and 10.

Hereinafter, until the user gives an instruction to end, each time the loading information is input, the CPU 10 sets the stackable range according to the total loaded weight, and the farthest position in the empty area of the stackable range. Is determined as the loading position. When the termination is instructed. The CPU 10 follows the procedure shown in FIG.
From S1070 to S1080 and RA so far
All the position information (see the load coordinate range information in FIG. 5) of the loaded items stored in M30 is read out, converted into a numerical form or a figure, and printed out from the printer 40.

The reason why the load is loaded in the farthest position from the center of gravity at that point in the loadable area is as follows. That is, the first in the stackable range 102 of FIG.
The position of the center of gravity of the vehicle having the load added is moved to, for example, position 101 between the position 107 where the second load is installed and the position 104 of the center of gravity of the vehicle only. However, since the subsequent load is installed at a position approaching the gravity center position 104 of only the vehicle, the vehicle gravity center position 101 including the load also approaches the gravity center position 104 of only the vehicle. Therefore, as the number of loads increases and the total weight of loads increases, the position of the center of gravity of the vehicle to which the load is added approaches the center of gravity 104 of only the vehicle, and the safety during transportation of the vehicle increases.

In the extreme case where the number of loaded items is small, the total weight of loaded items is small even if the number of loaded items is 1,
Moreover, since the vehicle is loaded within the loadable range corresponding to the total weight of the vehicle, the safety of the vehicle during transportation is ensured. Therefore, it is not necessary to calculate the position of the center of gravity in the loaded state. In addition, when the loaded weight exceeds 50% and the loadable range is expanded to the loadable area 103 and the load is loaded at the farthest position 106 at that time, the loadable area 102 has been loaded so far. Since there are multiple items loaded,
The position of the center of gravity of the loaded vehicle is the position of the center of gravity of only the vehicle.
The distance from 4 is small, and after that, the stackable area 103
As described above, the more the vehicle is loaded inside, the closer the center of gravity in the loaded state is to the center of gravity 104 of the vehicle only.

For the second embodiment, the following example can be implemented.

1) The shape indicating the loadable range may be a circle as shown in FIG. 12, or may be a rhombus or a rectangle, and a shape suitable for a transportation vehicle may be determined.

In addition, the following examples can be implemented for the first and second embodiments.

1) In the first and second embodiments described so far, the center of gravity of only the vehicle is fixed. Since the center of gravity position and the loadable range differ for each type of vehicle, it is possible to selectively set the vehicle information indicating the center of gravity position and the loadable range used for the above-described loading process according to the type of vehicle. . Such vehicle information is stored in a floppy disk for each type of vehicle, for example, in the form of a database. When determining the loading position, the user instructs the type of vehicle from the keyboard 70 and sends the CPU.
By reading the vehicle information corresponding to the instructed vehicle from the floppy disk via the FDD 90 and storing it in the RAM 30 by 10, the vehicle information necessary for the position determination processing can be taken out.

2) It is also possible to save the loading position information determined for all the loaded objects as a file on a floppy disk and use it for the next loading position determining process.

3) Not only the computer shown in FIG. 4 but also an information processing device (computer) such as a general-purpose computer, a workstation or a personal computer is used as the loading position optimizing device of the first and second embodiments. You can

4) When the stacking arrangement finally determined in the first embodiment or the second embodiment is stored in a floppy disk in the form of a file together with the stacking information, the stacking position of a similar stacked product is determined. The storage information of the floppy disk can be used as the input loading information at this time. In this case, the user instructs the CPU 10 to display the file from the keyboard 70, and the CPU 10 reads the file from the floppy disk via the FDD 40. The loading information and loading layout in the file are displayed on the display device 60. The user looks at the display screen and gives an instruction from the keyboard 70 to partially delete or change the stacking information on the display screen. As a result, the user does not have to perform an operation of inputting all loading information.

[0060]

As described above, according to the present invention,
Since the stacking position suitable for transportation can be determined without performing the center-of-gravity position calculation as in the conventional case, the stacking position determination time can be shortened. In addition, even if an additional load occurs after the load position is determined, the user can quickly determine the load position of the additional load without wasting the load placement determined so far.
