(Embodiment)
FIG. 1 is a diagram showing a configuration example of a loading support system according to an embodiment of the present invention. The loading support system 100 includes a loading support device 1, an acceleration sensor 2, a loading simulation device 3, and a fixed member master storage unit 4. The loading support apparatus 1 includes a transportation condition acquisition unit 11, a loading condition acquisition unit 12, a packing condition acquisition unit 13, a fixed location calculation unit 14, a fixed member selection unit 15, and a storage unit 16 as functional configurations. The acceleration sensor 2 is installed in a transportation means for transporting packages such as trucks, railroads, ships, and airplanes, and detects acceleration and inclination applied to the load being transported along the transportation route. The transportation condition acquisition unit 11 of the loading support device 1 includes information including acceleration and inclination detected by the acceleration sensor 2 including acceleration and inclination applied to the package and expected package during transportation on the transportation route. It is acquired from the acceleration sensor 2 as transport condition information indicating the transport condition, and is sent to the fixed location calculation unit 14. Or you may comprise so that an assumed value can be input into the transport condition acquisition part 11 of the loading assistance apparatus 1 as transport condition information. The acceleration and inclination applied to the package during transportation is defined by the transportation means for transporting the package and the transportation route. When there are a plurality of transportation means and transportation routes, the transportation information includes information for identifying the transportation means and transportation routes for transporting the package. The fixed location calculation unit 14 accumulates and stores the transportation condition information received from the transportation condition acquisition unit 11. The transport condition information may be stored and stored in the storage unit 16.

  The loading simulation apparatus 3 includes a loading position in a truck bed or a marine transportation container loaded on a ship when a package is loaded on a transportation means, the number of loading stages, and the adjacent state of surrounding objects. Enter the packing conditions including the conditions, the packing size (vertical length b, horizontal length c, height a) of the package, the mass m of the package, and the maximum static friction coefficient μ of the package. Is done. The maximum static friction coefficient μ of the package is the maximum static friction coefficient between the package and the surface on which the package is placed. The load condition acquisition unit 12 of the load support device 1 acquires the load condition information indicating the load condition from the load simulation device 3 and sends the load condition information to the fixed part calculation unit 14. The packing condition acquisition unit 13 acquires packing condition information indicating the packing conditions from the loading simulation device 3 and sends the packing condition information to the fixed part calculation unit 14. Or you may comprise so that an assumed value can be each input into the loading condition acquisition part 12 and the packing condition acquisition part 13 of the loading assistance apparatus 1 as loading condition information and packing condition information. The packing condition information includes information indicating the packing material of the package instead of the maximum static friction coefficient μ, the packing material of the package, the surface on which the package is placed, and the maximum static friction coefficient stored in advance by the fixed location calculation unit 14. The maximum static friction coefficient μ of the package may be calculated based on the correspondence table with μ. When transporting unpackaged luggage, the maximum coefficient of static friction between the unpackaged luggage and the surface on which the luggage is placed is used.

  Based on the loading condition information and the packing condition information received from the loading condition acquisition unit 12 and the packing condition acquisition unit 13 respectively, and the stored transportation condition information, the fixed part calculation unit 14 is a package ( Hereinafter, a portion that needs to be fixed (hereinafter referred to as a “fixed necessary portion”) and a force required for fixing (hereinafter referred to as a “fixed necessary force”) are calculated. The fixed part calculation unit 14 stores in the storage unit 16 the fixing necessary information indicating the fixing necessary package, the fixing necessary part, and the fixing necessary force. The fixed member master storage unit 4 includes a position to which the fixing member of each fixing member can be applied, a distance from another object to which the fixing member can be applied, strength when the fixing member is applied, and material cost of the fixing member. And a fixed member master including the total amount of work costs for fixing (hereinafter referred to as fixed costs).

  The fixing member selection unit 15 can be applied to a necessary fixing part of the fixing necessary package by referring to the fixing member master stored in the fixing member master storage unit 4 based on the fixing necessary information stored in the storage unit 16, and Then, narrow down the fixing members that satisfy the required fixing force, and select the cheapest fixing member among them. The fixing member selection unit 15 stores in the storage unit 16 the fixing member information indicating the fixing necessary package and the selected fixing member, and outputs the fixing member information and the fixing necessary information. The fixing member information may include the fixing cost of the selected fixing member. The output of the fixing member information and the fixing necessary information may be displayed on a screen, transmitted by e-mail, or printed out, for example.

  FIG. 2 is a conceptual diagram illustrating an example of a fixed candidate package according to the embodiment. From the loading condition information, the fixed location calculation unit 14 determines whether the bottom surface in the marine transportation container loaded on the truck bed or the ship is an X-Y plane and surrounding objects in the X-axis direction and the Y-axis direction. It is determined whether there is a possibility of moving all the packages loaded on the transportation means based on the adjacent situation. Regardless of external force, a surface having no object adjacent to at least one of the X-axis direction and the Y-axis direction is defined as a fixed candidate location, and a package having a fixed candidate location is defined as a fixed candidate package.

  FIG. 3 is a matrix diagram illustrating an example of a possibility that the package according to the embodiment moves. Fig.3 (a) has shown the possibility that the package 21 of FIG. 2 moves. When paying attention to the package 21, there are walls in the − direction of the X axis and the − direction of the Y axis, and there are other packages in the + direction of the X axis and the + direction of the Y axis. There is no. In the example of FIG. 3, the absence of a fixed candidate portion is indicated by x. Here, it is assumed that the loading platform will not fluctuate up and down, and movement in the Z-axis direction is not taken into account. If there is a possibility of sudden lowering, consider the movement in the Z-axis direction. When there is no fixed candidate location as in the package 21, the fixed location calculation unit 14 determines that the fixed location package is not a fixed candidate package. FIG. 3B shows a possibility that the package 22 of FIG. 2 needs to be fixed. Paying attention to the package 22, there is a wall in the negative direction of the Y axis, and there are other packages in the negative direction of the X axis and the positive direction of the Y axis, but nothing in the positive direction of the X axis. Therefore, there are fixed candidate locations. In the example of FIG. 3, the presence of a fixed candidate location is indicated by ◯. The fixed location calculation unit 14 determines that the package is a fixed candidate package when there is at least one fixed candidate location like the package 22. The determination as to whether or not the package is a fixed candidate package is made for all packages loaded on the transportation means.

  FIG. 4 is a conceptual diagram illustrating a force applied to the fixed candidate package according to the embodiment and a calculation method of the direction thereof. The fixed part calculation unit 14 calculates the force applied to the fixed candidate package and its direction for all fixed candidate packages and fixed candidate parts based on the transportation condition information and the packing condition information. When there are a plurality of transportation means and transportation routes, the fixed location calculation unit 14 reads and uses the transportation condition information of the transportation means and transportation routes set in the fixed candidate package. The fixed location calculation unit 14 determines whether or not fixing is necessary from the force applied to the fixed candidate package and its direction. The fixed part calculation unit 14 calculates the necessary fixing force, which is the minimum force necessary for fixing the fixed necessary package, by using the fixed candidate package that needs to be fixed as the necessary fixed package. The fixed part calculation unit 14 stores in the storage unit 16 the fixing necessary information indicating the fixing necessary package, the fixing necessary part, and the fixing necessary force.

  For example, in the fixed candidate package 23 of FIG. 4A, the mass of the package is m, the maximum static friction coefficient of the packing material is μ, the maximum acceleration extracted from the transportation condition information is α, the maximum slope is θ, When the gravity acceleration is g, and (mgsinθ + mαcosθ)> μ (mgcosθ−mαsinθ), it is determined that the load of the fixed candidate package 23 is generated, that is, fixing is necessary. Here, the maximum acceleration α and the maximum inclination θ that are expected during transportation are used to determine whether or not load deviation occurs, but the acceleration and inclination included in the transportation condition information are associated with each other. In the case of being present, it may be determined whether or not a load deviation occurs from a combination of acceleration and inclination that may occur on the transportation route. The left side of the inequality is the force that moves the fixed candidate package 23, and the right side is the friction force that is opposite to the force that moves the fixed candidate package 23. When the fixing is necessary, the fixing part calculation unit 14 determines the fixing candidate package 23 as the fixing necessity package, and determines the hatched surface of the fixing candidate packing 23 as the fixing necessary part. In addition, the fixed portion calculation unit 14 sets (mgsinθ + mαcosθ) −μ (mgcosθ−mαsinθ), which is the minimum force necessary for fixing, as a necessary force for fixing. In the example of FIG. 4A, it is assumed that there is no object adjacent to a surface other than the bottom surface of the fixed candidate package 23. For example, as shown in the package 22 of FIG. When there is the object 21, the force received in the + direction of the X axis from the package 21 is also taken into consideration in the calculation. Further, when the transportation condition includes not only horizontal acceleration but also vertical acceleration (vibration), it is added to the calculation as a force received in the vertical direction from the ground.

  For example, in the fixed candidate package 24 in FIG. 4B, the vertical length of the package is b, the height is a, the mass is m, the maximum acceleration extracted from the transportation condition information is α, and the maximum slope is When θ and gravity acceleration are g, when a / 2 (mgsinθ + mαcosθ)> b / 2 (mgcosθ−mαsinθ), it is determined that the fixed candidate package 24 is collapsed, that is, needs to be fixed. . As in the case of FIG. 4A, here, it is determined whether or not cargo collapse occurs using the maximum acceleration α and the maximum inclination θ expected during transportation. If the acceleration and the inclination included in the are associated with each other, it may be determined whether or not the cargo collapse occurs from a combination of the acceleration and the inclination that may occur on the transportation route. When the left side of the inequality is a line extending from the point A in the direction perpendicular to the paper surface, the right side is a line extending from the point A in the direction perpendicular to the paper surface. In this case, the counterclockwise moment is applied to the fixed candidate package 24. When the fixing is necessary, the fixing part calculation unit 14 determines the fixing candidate package 24 as the fixing necessity package, and determines the surface extending in the height direction from the rotation axis of the fixing candidate package 24 as the fixing necessary part. . In addition, the fixed point calculation unit 14 sets a / 2 (mg sin θ + mα cos θ) −b / 2 (mg cos θ−m α sin θ), which is a minimum force necessary for fixing, as a necessary force for fixing. In the example of FIG. 4B, it is assumed that there is no object adjacent to a surface other than the bottom surface of the fixed candidate package 24, and the package is made in the negative direction of the X axis, for example, the package 22 of FIG. When there is the object 21, the force received in the + direction of the X axis from the package 21 is also taken into consideration in the calculation. Further, when the transportation condition includes not only horizontal acceleration but also vertical acceleration (vibration), it is added to the calculation as a force received in the vertical direction from the ground.

  In the example of the fixed candidate package 23 in FIG. 4A, when (mgsinθ + mαcosθ) ≦ μ (mgcosθ−mαsinθ), and in the example of the fixed candidate package 24 in FIG. 4B, a / 2 (mgsinθ + mαcosθ) If ≦ b / 2 (mgcosθ−mαsinθ), there is no possibility of load displacement and collapse, so that the fixed candidate package 23 and the fixed candidate package 24 need not be fixed. The fixed location calculation unit 14 may further store in the storage unit 16 packing-unnecessary information indicating a package that has been determined to be unfixed. As shown in FIG. 4, when determining whether or not load deviation and collapse occur using the maximum acceleration α and the maximum inclination θ expected during transportation, the transportation condition information is stored and stored. Instead, the maximum value of the acceleration and the inclination included in the transportation condition information acquired by the transportation condition acquisition unit 11 may be stored and overwritten and stored every time it is updated.

  FIG. 5 is a conceptual diagram showing a method for selecting a fixing member to be applied to a fixing required portion according to the embodiment. The fixing member selection unit 15 selects the cheapest fixing member that satisfies the conditions of the necessary fixing position and the necessary fixing force indicated by the necessary fixing information. As shown in FIG. 5 (a), the package 25 required for fixing has a hatched surface where fixing is required, and the required fixing force is 5N. Moreover, the space | interval with the packing material adjacent to the fixing required packing material 25 is 30 cm.

  FIG. 6 is a diagram illustrating an example of a fixing member master according to the embodiment. In the example of FIG. 6, the fixed member master includes a “member name” indicating the name of the fixed member, an “applicable position” indicating a position where the fixed member can be applied, and other objects to which the fixed member can be applied. It includes items of “applicable interval” indicating the interval, “strength” indicating the strength when the fixing member is applied, and “amount” indicating the fixing cost of the fixing member. In practice, the strength of the fixing member is a value that can withstand repeated loads, and takes into account variations in the fixing member. Referring to the fixing member master shown in FIG. 6, the fixing member options are wood pieces, cardboard + wood pieces, and airbags.

  5A is located at the third level from the floor, the piece of wood whose “applicable position” is the floor does not satisfy the requirements for the applicable position. For this reason, the fixing member selection unit 15 narrows the options to corrugated cardboard + wood pieces and airbags that are not limited to “applicable positions”. FIG. 5B shows an example in which corrugated cardboard + wood pieces are applied to the fixed packing 25. An example in which an airbag is applied to the fixed package 25 is shown in FIG. Subsequently, since the distance between the package 25 adjacent to the package 25 and the adjacent package in FIG. 5A is 30 cm and the necessary force is 5 N, the fixing member remaining in the option is “applicable interval”. There is no restriction on the cardboard and the piece of wood having a “strength” of 10 N, and an airbag having a “strength” of 500 N with an “applicable interval” within 50 cm. Since both cardboard + wood pieces and airbags can be applied to the package 25 that needs to be fixed as fixing members, the fixing member selection unit 15 compares the "amount" and the cardboard + wood pieces of 500 yen are 1000 yen. Therefore, the cardboard and the piece of wood are selected as the fixing member for the fixed package 25. The fixing member selection unit 15 stores in the storage unit 16 fixing member information indicating the fixing necessary package and the selected fixing member, and outputs the fixing member information and the fixing necessary information. At this time, the fixing member selection unit 15 may output the packing unnecessary information together with the fixing member information and the fixing necessary information.

  FIG. 7 is a flowchart illustrating an example of the operation of the fixed location calculation process according to the embodiment. The fixed portion calculation process is repeatedly executed while the loading support apparatus 1 is activated. Based on the loading condition information, the fixed point calculation unit 14 of the loading support apparatus 1 determines whether there is a fixed candidate package among the packages loaded on the transportation means (step S11). In step S11, as described with reference to FIGS. 2 and 3, the fixed location calculation unit 14 determines a surface having no object adjacent to at least one of the X axis direction and the Y axis direction as a fixed candidate location, and the fixed candidate. The package with the location is determined as the fixed candidate package. If there is no fixed candidate package (step S11; NO), the process ends. When there is a fixed candidate package (step S11; YES), the fixed location calculator 14 calculates the force applied to the fixed candidate package and its direction based on the transportation condition information and the packing condition information (step S12). In step S12, as described with reference to FIG. 4, the fixed point calculation unit 14 uses the maximum acceleration α, the maximum inclination θ, and the gravitational acceleration g extracted from the transportation condition information to move the fixed candidate package. And the reverse friction force and the moment applied to the fixed candidate package. The fixing part calculation unit 14 determines whether or not fixing is necessary from the force applied to the fixing candidate package and its direction (step S13). If fixing is not necessary (step S13; NO), the process proceeds to step S16. Transition. In step S13, as described with reference to FIG. 4A, the fixed point calculation unit 14 needs to be fixed when the force for moving the fixed candidate package in the direction where there is no adjacent object is larger than the reverse frictional force. It is determined that As described with reference to FIG. 4B, the fixed point calculation unit 14 needs to be fixed when the moment applied to the fixed candidate package in the direction where there is no adjacent object is larger than the moment applied to the adjacent object in the direction. It is determined that

  When the fixing is necessary (step S13; YES), the fixing point calculation unit 14 sets the fixing candidate package as the fixing necessary packing, and calculates the fixing necessary force from the force applied to the fixing necessary packing and its direction ( Step S14). In step S14, as described with reference to FIG. 4A, the fixed point calculation unit 14 uses the difference between the force that moves the fixed package in the direction where there is no adjacent object and the reverse friction force as the fixed force. calculate. As described with reference to FIG. 4B, the fixed point calculation unit 14 uses the difference between the moment applied in the direction where there is no adjacent object and the moment applied in the direction where there is an adjacent object as the necessary force for fixing. calculate. At this time, the fixed portion calculation unit 14 may calculate a value obtained by adding an arbitrary value to the minimum force necessary for fixing the necessary packing for fixing, and multiply the acceleration by a safety factor. You may expect a safety factor. The fixed part calculation unit 14 stores the necessary fixing information indicating the necessary fixed package, the necessary fixing part, and the necessary fixing force in the storage unit 16 (step S15). When there is an unprocessed fixed candidate package (step S16; YES), the process returns to step S12, and steps S12 to S16 are repeated. If there is no unprocessed fixed candidate package (step S16; NO), the process ends.

  FIG. 8 is a flowchart illustrating an example of the operation of the fixing member selection process according to the embodiment. The fixing member selection process is repeatedly executed while the loading support apparatus 1 is activated. The fixing member selection unit 15 of the stacking support apparatus 1 narrows down the fixing member options indicated by the fixing member master stored in the fixing member master storage unit 4 based on the fixing necessary information at the applicable positions (step S21). In the example of FIG. 5 and FIG. 6, the fixed package 25 is located at the third level from the floor. Therefore, in step S <b> 21, the fixed member selection unit 15 selects “applicable fixed member options for the fixed package 25. Narrow down to corrugated cardboard + wood pieces and airbags with no restrictions on position. The fixing member selection unit 15 narrows down fixing member options at applicable intervals based on the fixing necessary information (step S22). The fixing member selection unit 15 narrows down fixing member options by strength based on the necessary fixing information (step S23). In the example of FIGS. 5 and 6, the interval between the fixed package 25 and the adjacent package is 30 cm, and the necessary force is 5 N. Therefore, the fixing member selection unit 15 performs steps S22 and S23. As an option of fixing members of the package 25 to be fixed, there is no restriction on the “applicable interval”, and the “strength” is 10N corrugated cardboard + a piece of wood, and the “applicable interval” is within 50 cm and the “strength” is 500N. And leave.

  The fixing member selection unit 15 selects the cheapest fixing member among the narrowed fixing members (step S24). In the examples of FIGS. 5 and 6, the fixing member selection unit 15 compares the “money amount” in step S24, and the cardboard of 500 yen and the piece of wood are cheaper than the airbag of 1000 yen, so the fixing is necessary. Corrugated cardboard + wood piece is selected as a fixing member for the package 25. The fixing member selecting unit 15 stores the fixing member information indicating the fixing necessary package and the selected fixing member in the storage unit 16 (step S25), and outputs the fixing member information and the fixing necessary information (step S26). If there is a fixed package that requires no fixing member (step S27; YES), the process returns to step S21, and steps S21 to S27 are repeated. If there is no necessary fixed package for which no fixing member is selected (step S27; NO), the process is terminated.

  As described above, according to the loading support apparatus 1 of the embodiment, when a package is transported, the fixing necessary portion and the fixing necessary force of the fixed necessary packing are automatically calculated, and the fixing necessary portion of the fixing necessary packing is required. By automatically selecting the cheapest fixing member that has the strength to meet the required fixing force and is applicable to the The occurrence of collapse can be prevented and the cost can be reduced. In addition, it is possible to prevent the occurrence of an excessive fixing cost of the fixing member due to the application of the fixing member to a place where the fixing is unnecessary or the application of the fixing member having an excessive strength. As a result, the number of fixing members can be reduced, which in turn leads to a reduction in the fuel cost of the transportation means, and further cost reduction can be expected.

  In the above embodiment, under the loading conditions indicated by the loading condition information acquired by the loading condition acquisition unit 12, it is necessary to fix the package, the fixing required portion, the fixing force, the fixing member to be applied, and the fixing cost of the fixing member. However, the loading conditions may be changed under conditions that do not reduce the loading rate on the transportation means. The loading rate on the transportation means is a value obtained by dividing the total outer volume of all the packages loaded on the transportation means by the maximum volume that can be loaded on the transportation means. This modification will be described.

  In the modification, the fixing member information includes the fixing cost of the selected fixing member. The loading condition information indicating the loading condition changed under conditions that do not reduce the loading rate on the transportation means is input to the loading condition acquisition unit 12, and the fixed location calculation unit 14 and the fixed member selection unit 15 respectively perform the fixed location calculation processing and the fixation. By repeating the member selection process, the fixed required package that is calculated under multiple loading conditions, the fixed required location, and the fixed required information indicating the required fixed force, and the fixed selected based on the fixed required information Fixing member information indicating the member and the fixing cost of the selected fixing member is stored in the storage unit 16. The fixing member selection unit 15 can calculate the cheapest loading condition by comparing the fixing costs included in the fixing member information stored in the storage unit 16. In this case, information indicating the cheapest loading condition is stored in the storage unit 16 in association with the fixing member information and the fixing necessary information.

  Further, it is more effective if the fixing member information and the fixing necessary information and the information indicating the cheapest loading condition are combined with the visual information of the loading simulation device 3. That is, the loading position in the marine transportation container loaded on the truck bed or the ship when the package is loaded on the transportation means, the number of loading stages, and the adjacent state of the surrounding objects, which are input to the loading simulation apparatus 3 Visual information that visualizes the packing conditions including the packing conditions including the packing size, the packing size of the package, the mass of the package, and the maximum static friction coefficient of the package, the fixing member information and the fixing necessary information, and the cheapest By outputting together with information indicating the loading conditions and presenting it to the loading site on the transportation means, it becomes possible to more effectively prevent the package from being misaligned and damaged due to collapse during transportation. . In addition, it is possible to reduce the material cost of the excessive packing member and the work cost necessary for fixing, and the time required for fixing the load can be reduced.

  In the above-described embodiment, the fixed part calculation unit 14 of the loading support device 1 calculates the necessary fixed package, the fixed necessary part, and the necessary fixing force. However, the present invention is not limited thereto, and the fixed part calculation unit 14 needs to be fixed. Only the location and the necessary fixing force may be calculated. Further, the loading support device 1 does not include the fixing member selection unit 15, and the processing of the fixing member selection unit 15 may be executed by another device or manually by a person. For example, when the fixing method of the package transported in a transportation means such as a truck, a railroad, a ship, and an aircraft is only one type of fixing member such as a rope, the fixing point calculation unit 14 sets the fixing necessary packing and the fixing necessary portion. May be calculated and the fixed necessary information indicating the fixed necessary package and the necessary fixed portion may be output as visual information on a monitor or a form. By outputting such information necessary for fixation as visual information and instructing the loading site of the transportation means, it becomes possible to prevent the package from being displaced during transportation and from being damaged due to the collapse of the load. It is possible to reduce the time required for fixing. The fixed location calculation unit 14 may calculate only the necessary fixing force. For example, when designing a new fixing member when there is a problem with its strength, such as damage to an existing fixing member when a package is transported by means of transportation such as trucks, railroads, ships, aircraft, etc. The necessary fixing force output from the fixing member selection unit 15 can be used as a reference for design.

  In the above-described embodiment, the fixing candidate portion and the fixing necessary portion are determined in terms of the surface. In addition, the fixed point calculation unit 14 may determine whether or not the load is generated on both the load deviation and the load collapse of the package loaded on the transportation means, and whether or not the load occurs on one side. Also good. The fixing | fixed location calculating part 14 determines that fixation is required, when it determines with at least any one of the load shift | offset | difference of a package and a load collapse.
