Further, the number of support legs 91 is not limited to four.

  Next, the production | generation of the loading information of the several package by the loading information generation apparatus 1 is demonstrated along FIG. In the present embodiment, the structure of each of the plurality of packing bodies is approximately the same as that of the packing body 7 shown in FIGS. Further, the size, weight, and center of gravity of each of the plurality of packing bodies are not necessarily the same.

  In the loading information generating device 1 shown in FIG. 1, first, for a plurality of target devices of a package, three-dimensional CAD data of each target device is input from the input unit 21 and stored in the storage unit 11 (step S11). . The three-dimensional CAD data includes, for each of a plurality of parts constituting each target apparatus, part data indicating the size, weight, and center of gravity of the part, and the position of the part in each target apparatus. Note that the component data may include information indicating the volume and specific gravity of the component instead of the weight of the component.

  Subsequently, steps S12 to S18 described later are performed for each of the plurality of target devices, and the size, weight, and center of gravity position of the package are obtained for each of the plurality of packing bodies corresponding to the plurality of target devices. Hereinafter, steps S12 to S18 will be described by paying attention to one package 7 (see FIG. 2). Note that the size of the package means the length of the package in the X direction, the Y direction, and the Z direction.

  When the three-dimensional CAD data of the target device 9 is stored, the CAD data processing unit 12 obtains the size, weight, and barycentric position of the target device 9 based on the three-dimensional CAD data and stores them in the storage unit 11. (Step S12). The size of the target device 9 is obtained based on the size and position of all the parts that constitute the target device 9. The weight of the target device 9 is obtained by adding the weights of all the parts. The center-of-gravity position of the target device 9 is obtained by dividing the product sum of the weights and the center-of-gravity positions (that is, the X, Y, and Z coordinates) of all components by the weight of the target device 9. The size of the target device 9 may be obtained from only the size and position of the parts exposed to the outside among all the parts of the target device 9.

  Next, the automatic design unit 13 performs a temporary design of the lower back board 81 and the fixing jig 85 based on the size and weight of the target device 9 (step S13). In the temporary design of the lower back board 81, the lengths of the lower back board 81 in the X direction and the Y direction are determined so as to be larger than the outer shape of the target device 9 in plan view. Further, based on JIS (Japanese Industrial Standards) Z1402, Z1403, etc., the width and thickness of the sliding material 811, the sliding material 812, the header 813, the loaded floor material 814, and the unloaded flooring material 815 based on the weight of the target device 9. Are determined, and the arrangement of the loaded floor material 814 and the unloaded floor material 815 is determined based on the distance between the support legs 91 (see FIG. 4) of the target device 9.

  In the temporary design of the fixing jig 85 shown in FIG. 5, a fixing jig having an appropriate shape and size from a database of fixing jigs stored in advance in the storage unit 11 based on the shape and size of the support legs 91. A set of 85 (in this embodiment, the fixing jig main body 851 and the bolt 852) is extracted. Then, assuming that the weight of the target device 9 is equally applied to all the support legs 91, the load applied to each support leg 91 (in this embodiment, ¼ of the weight of the target device 9, hereinafter “ The optimum fixing jig 85 is selected from the set of fixing jigs 85 extracted based on “average load”.

  In the automatic design unit 13 (see FIG. 1), when the temporary design of the lower back board 81 and the fixing jig 85 is completed, the temporary design result of the lower back board 81 and the fixing jig 85 is obtained based on the position of the center of gravity of the target device 9. The necessary reinforcement design is performed (step S14). In the reinforcement design of the lower back board 81, the reinforcement design of the sliding material 811, the header 813 or the load floor material 814 is performed. In the reinforcement design, first, a load (hereinafter referred to as “actual load”) actually applied to each of the plurality of support legs 91 is obtained from the weight of the target device 9 and the position of the center of gravity. When the reinforcement design of the load floor material 814 is performed, the load floor material 814 on which the support leg 91 whose actual load is larger than the average load (that is, the support leg 91 close to the center of gravity position) is selected. Then, the width and thickness of the load floor material 814 are increased as necessary so that the load floor material 814 can support the actual load, or the material and structure of the load floor material 814 are changed to high strength. Is done. The said change is performed based on the reinforcement database which shows the relationship between the difference of an actual load and an average load, and reinforcement, and the said reinforcement database is memorize | stored in the memory | storage part 11 previously. In addition, when making the load floor material 814 thick, in order to make the height with which all the support legs 91 are mounted, other load floor material 814 is also made the same thickness, or other load floor material 814. An auxiliary plate that compensates for the lack of thickness is disposed above.

  When the reinforcement design of the lubricant 811 or the header 813 is performed, for example, the lubricant 811 or the header 813 close to the support leg 91 whose actual load is larger than the average load is selected, and the above-described reinforcement database is included as necessary. Based on this, the width and thickness of the lubricant 811 and the header 813 are increased, and the material and structure are changed to high strength. From the viewpoint of simplifying the procurement of each member, the specifications of all the load floor material 814, the lubricant material 811 and the header 813 are the same as the load floor material 814, the lubricant material 811 and the header in which the above-described reinforcement design is performed. 813 (the same applies to the fixing jig 85 described below).

  When the reinforcing jig 85 is designed to be reinforced, the fixing jig 85 that fixes the support leg 91 whose actual load is larger than the average load is the optimum fixing jig 85 based on the actual load (that is, the average load). The fixing jig 85) having a larger load resistance than the fixing jig 85 selected based on the above is selected. In the case of the target device 9 having a high center of gravity, the force applied to the fixing jig 85 is increased when a lateral load is applied to the target device 9. For this reason, when the center-of-gravity position in the Z direction of the target device 9 is larger than a predetermined threshold value, an appropriate fixing jig 85 is selected again based on the center-of-gravity position in the Z direction. In step S14, only one of the lower waist plate 81 and the fixing jig 85 may be reinforced.

  When the reinforcing design of the lower back 81 and the fixing jig 85 is completed, the automatic design unit 13 designs the upper structure 82 of the packing material 8 based on the size, weight, and the like of the target device 9 (step S15). . In the present embodiment, the sizes of the ceiling plate 821 and the outer plate 822 of the upper structure 82 are determined based on the size of the target device 9, and the ceiling plate 821 and the outer plate 822 are determined based on the weight of the target device 9, JIS Z1403, and the like. The thickness of the outer plate 822 is determined. And the magnitude | size (The magnitude | size of the packing material 8 of the state which packed the target apparatus 9 in this Embodiment) is calculated | required, and it memorize | stores in the memory | storage part 11 (refer FIG. 1) (step S16). .

  Subsequently, the weight center-of-gravity calculation unit 14 obtains the weight and center-of-gravity position of the packing material 8 and the fixing jig 85 based on the design results of the lower back board 81, the upper structure 82, and the fixing jig 85 by the automatic design unit 13. And stored in the storage unit 11 (step S17). Specifically, the weights of the members of the lower waist plate 81 and the upper structure 82 are summed to obtain the weight of the packing material 8, and the weight and the center of gravity of each member (that is, the X coordinate, the Y coordinate, and the Z coordinate). Is divided by the total weight of the packaging material 8 to obtain the position of the center of gravity of the packaging material 8. Further, the weight of the fixing jig 85 is obtained based on the type of the fixing jig 85 determined in step S14, and the product sum of the weight of the fixing jig 85 and the position of the center of gravity is divided by the total weight of all the fixing jigs 85. By doing so, the center-of-gravity positions of the plurality of fixing jigs 85 are obtained.

  Next, the weight center of gravity calculation unit 14 determines the weight of the target device 9 stored in the storage unit 11 and the position of the center of gravity, and the weight and center of gravity of each of the packing material 8 and the fixing jig 85. The weight and the center of gravity position are obtained and stored in the storage unit 11 (step S18). Specifically, the weights of the target device 9, the packing material 8, and the fixing jig 85 are summed to obtain the weight of the packing body 7. By dividing the sum of products by the weight of the packaging body 7, the position of the center of gravity of the packaging body 7 is obtained.

  In the loading information generation device 1, the size, weight, and center of gravity of each of the plurality of packing bodies are stored in the storage unit 11 by performing steps S <b> 12 to S <b> 18 for each of the plurality of packing bodies. The storage unit 11 stores in advance the unloading direction of each of the plurality of packing bodies. The unloading direction is information indicating from which direction of the transport space the package loaded in the transport space is unloaded. For example, when the transport space is a cargo room of a truck, the unloading direction is the direction from the front side to the rear side of the transport space, the direction from one side of the left-right direction to the other side, or the lower side to the upper side. Direction.

  The storage unit 11 also stores in advance a loading restriction condition unique to a conveyance space that accommodates a plurality of packages as cargo. The loading restriction conditions include the size of the conveyance space, the allowable weight of the cargo loaded in the conveyance space, the allowable range of the center of gravity position of the cargo, and the loading direction of the cargo. The allowable range of the center of gravity position of the cargo may be changed according to the weight of the cargo. The cargo loading direction is information indicating from which direction of the conveyance space the cargo is carried into the conveyance space. For example, when the transport space is a cargo space of a truck, the loading direction is the direction from the rear side to the front side of the transport space, the direction from one side of the left-right direction to the other side, or the upper side to the lower side. It is the direction to face. The storage unit 11 stores a loading restriction condition for a plurality of types of conveyance spaces.

  Subsequently, the product design unit 15 (refer to FIG. 1), based on the product space restriction conditions, and the size, weight, center of gravity position, and unloading direction of each of the plurality of packing bodies. Each arrangement position in the conveyance space of the package is determined (step S19). The arrangement position is represented by the position of the package in the longitudinal direction and the width direction of the transport space, and the direction of the package.

  The arrangement position is determined by various procedures in accordance with the number and size of the package, the type and size of the transport space, and the like. Hereinafter, an example of a preferable arrangement position determination when the cargo room of the truck is a conveyance space will be described. In the following example, the arrangement position of the package is determined on the condition that the other package is not arranged on the package (so-called flat stacking condition). As information on each package, whether or not another package is stacked on the upper side (so-called “uploading”) is stored in the storage unit 11 in advance, and the arrangement position in consideration of the upper stacking may be determined. .

  In determining the arrangement position, first, the largest and heaviest package is selected from the plurality of packages, and the arrangement position of the package in the transport space is determined. The arrangement position of the package in the width direction of the transport space (that is, the left-right direction of the truck) is such that the center of gravity of the package coincides with the center in the width direction of the allowable range of the center of gravity position in the transport space (that is, Determined to lie on a central line extending in the longitudinal direction). Due to the relationship between the size of the package and the size of the transport space, if the center of gravity of the package cannot be matched with the center in the width direction of the allowable range, the position between the center of gravity of the package and the center The arrangement position of the package is determined so that the distance in the width direction is as small as possible.

  The arrangement position of the packing body in the longitudinal direction of the transport space is the innermost side in the loading direction of the transport space. For example, when a package is carried in by a forklift from the rear side of the cargo compartment of the truck, the package is arranged on the foremost side of the cargo compartment. Further, the direction of the package is determined so that the unloading can be easily performed in consideration of the unloading direction of the package. For example, when the package is unloaded from the rear side of the cargo compartment by a forklift, the direction of the package is such that the fork insertion port 816 (see FIG. 3) faces the rear side (that is, the front side in the unloading direction). To be located). When there are a plurality of the largest and heaviest packing bodies, all of these packing bodies are arranged in order from the back side in the loading direction. If all of the largest and heaviest packages cannot be stacked due to restrictions on the size of the transport space, the arrangement position of the largest number of packages that can be stacked among the largest and heaviest packages is determined. After that, a small package that can be loaded is selected, and the arrangement position and orientation of the package are determined by the same method. The package that could not be stacked is stacked on another truck.

  In the loading design unit 15, when determining the arrangement position of each package, the total weight of the package and all the packages whose arrangement positions have been determined is compared with the allowable weight of the conveyance space. When the total weight is equal to or less than the allowable weight, the arrangement position of the package is determined. On the other hand, when the total weight is larger than the allowable weight, the arrangement position of the package is not determined, and another package that is lighter than the package is selected as an object for determining the arrangement position. Note that the package whose placement position has not been determined is stacked on another truck.

  In the loading design unit 15, the arrangement position of the packing body is determined so as to be arranged in the longitudinal direction along the center line of the luggage compartment in order from the large and heavy packing body. When all of the plurality of packing bodies cannot be arranged in the longitudinal direction due to the restriction of the size of the conveyance space, the packing bodies that cannot be arranged are arranged in the space in the width direction of the packing body whose arrangement position has been determined. When the arrangement positions of all the packages that can be stacked are determined, the center of gravity of these entire packages (that is, the center of gravity of the cargo) is obtained and may be within the allowable range of the center of gravity of the transport space. It is confirmed. When the position of the center of gravity of the cargo is outside the allowable range, the position of the center of gravity is determined and compared with the allowable range, except for one package that has been positioned immediately before, until the position is within the allowable range. In this case, the removed package is stacked on another truck.

  When step S19 ends, the arrangement position, weight and center of gravity of each of the plurality of packing bodies determined by the loading design unit 15, and the weight of the heaviest packing body among the plurality of packing bodies (hereinafter referred to as “packaging body maximum”). Loading information including the weight and center of gravity of the whole of the plurality of packages (hereinafter referred to as “cargo weight” and “cargo center of gravity”) are output by the output unit 16 (see FIG. 1). Then, the data is output to the printing paper on which printing is performed by the display 22 or the printer 23 (step S20).

  The arrangement position, size, weight, and center of gravity position of each of the plurality of packages are displayed in, for example, a table format. The arrangement position of each package is indicated, for example, as an X coordinate, a Y coordinate, and a Z coordinate of a predetermined vertex (a lower left vertex in FIG. 7.B described later) of each package. The size of each package is indicated by lengths in the X direction, Y direction, and Z direction, and the center of gravity is indicated by numerical values of the X, Y, and Z coordinates. The maximum package weight, cargo weight, and cargo gravity center position are displayed together with the allowable weight of the conveyance space 6 and the allowable range of the gravity center position.

  Each arrangement position, size and center of gravity position of the plurality of packages, and the center of gravity position of the cargo are preferably as shown in FIG. A and FIG. As shown to B, it is shown on the two-dimensional image of the conveyance space 6 output from the output part 16. FIG. FIG. A is a plan view of the conveyance space 6, and the right side in the figure is the front. FIG. B is a left side view of the conveyance space 6, and the packing bodies in both figures are denoted by reference numerals 7a to 7e. In addition, it is also preferable that a three-dimensional image of the transport space 6 is output from the output unit 16 and the arrangement position, size, center of gravity position, and cargo center-of-gravity position of a plurality of packing bodies are indicated on the three-dimensional image. .

  The gravity center positions of the packing bodies 7a to 7e on the two-dimensional image are, for example, FIG. A and FIG. As shown in B, a mark 71 (a mark combining a circle and a cross or the like) is displayed. Similarly, the position of the center of gravity of the cargo is displayed with a mark 72 (colored circle or the like). FIG. A and FIG. In B, an allowable range 61 of the center of gravity position of the transport space 6 is shown surrounded by a two-dot chain line. The display of the center of gravity position on the three-dimensional image may be performed similarly. Alternatively, only the outline of the package is indicated by a straight line or the like, and a mark indicating the position of the center of gravity in the space inside the outline (a combination of a sphere and arrows extending from the center in the X, Y, and Z directions, respectively) May be displayed.

  As described above, in the product information generation device 1, the CAD data processing unit 12 can obtain the weight and the center of gravity of the target device with high accuracy based on the three-dimensional CAD data. For this reason, the weight and center-of-gravity position of the package including the target device can be obtained with high accuracy, and as a result, the design for loading a plurality of packages can be performed appropriately. Further, by outputting the cargo weight and the cargo gravity center position to the display 22 or the printing paper, the operator can easily confirm that the cargo satisfies the loading restriction condition of the conveyance space.

  In the loading information generating device 1, the arrangement positions of the plurality of packing bodies are output, so that the operator can easily check the arrangement positions of the respective packing bodies. Thereby, the order of carrying in / out to the conveyance space of a package can be confirmed easily, and the carrying in / out operation of a package can be performed efficiently. Moreover, each arrangement position of a some package is shown on the two-dimensional image or three-dimensional image of conveyance space. For this reason, an operator can confirm the arrangement position of each package more easily, and can carry out the carrying-in / out operation of a package more efficiently.

  Furthermore, since the maximum weight of the package is output by the output unit 16, it is possible to easily and quickly select a fork of a forklift that conveys the package, and to carry out the loading / unloading operation of the package more efficiently. Can do. In the loading design unit 15, the arrangement positions of the plurality of packing bodies are determined based on the respective unloading directions, and therefore, the packing body unloading operation (that is, unloading) can be performed more efficiently.

  The output unit 16 outputs the weight and the center of gravity of each of the plurality of packing bodies, so that the weight and the center of gravity of the packing body can be obtained when the operator carries the packing body into or out of the transport space. Since the packaging body can be lifted in consideration of the position, the packaging body can be safely conveyed while preventing the packaging body from being inclined or toppling. Further, as described above, the gravity center position of each of the plurality of packing bodies is indicated on the two-dimensional image or the three-dimensional image of the conveyance space. For this reason, an operator can grasp | ascertain the gravity center position of a package easily, and can convey a package more safely.

  The automatic design unit 13 can automatically design the lower back of the packing material and the fixing jig including reinforcement based on the size, weight, and center of gravity of the target device. Thereby, the weight and center-of-gravity position of the package can be obtained with higher accuracy, and as a result, the loading design of a plurality of packages can be performed more appropriately.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to the said embodiment, A various change is possible.

  In step S14 described above, the reinforcement design of the sliding member 811, the header 813, and the load flooring member 814 of the lower back panel 81 is performed. These members are adjusted according to the weight of the target device 9, the degree of deviation of the center of gravity position, and the like. May be designed to reinforce a part of or other members of the lower waist plate 81. However, in the reinforcement design of the lower waist plate 81, it is more preferable to design the reinforcement of the sliding member 811, the header 813, or the load floor member 814 that is easily affected by the deviation of the center of gravity of the target device 9. In addition, when there is not much bias in the center of gravity of the target device 9, the reinforcement design for the lower waist plate 81 and the fixing jig 85 is not performed, and the temporary design result of step S13 may be used as it is. In the loading information generation device 1, when the size of the packing body 7 and the weight and center of gravity of the packing material 8 are obtained in advance by other means and stored in the storage unit 11, the automatic design unit 13 is omitted. May be.

  Various packing materials 8 may be used for packing the target device 9. For example, the upper structure 82 of the packing material 8 may have a shape in which one of the ceiling plate 821 and the outer plate 822 that is four side surfaces is omitted, or may be formed of various materials other than wood. . When the upper structure 82 is formed of wood, the upper structure 82 is designed based on the size and weight of the target device 9, but the upper structure 82 is formed of a material having a relatively low strength such as cardboard. In this case, the superstructure 82 is designed based only on the size of the target device 9. In other words, the superstructure 82 is designed based on at least the size of the target device 9.

  The package 7 may be formed, for example, by covering the target device 9 fixed on the lower back board 81 with a vinyl sheet and binding the vinyl sheet together with the target apparatus 9 and the lower lower board 81 with a rope. In this case, the lower back 81, the vinyl sheet, and the rope serve as the packing material 8 for packing the target device 9. The package 7 may be formed by binding the target device 9 fixed on the lower back board 81 together with the lower back board 81 with a rope or the like. In addition, the one in which the target device 9 is simply fixed to the lower waist plate 81 by the fixing jig 85 can be regarded as the package 7. Note that the packing material 8 does not necessarily have to have the lower back plate 81 as long as the target device 9 is packed. The article to be packed packed with the packing material 8 may be various things other than a large-sized apparatus used for semiconductor manufacturing or the like.

  The configurations in the above-described embodiments and modifications may be combined as appropriate as long as they do not contradict each other.
