Description

Method for transporting package and method for planning transportation of package

Technical Field

The present invention relates to a method for transporting a package including a laminate of a glass plate and a protective sheet, and a method for planning the transportation of the package.

Background

As is well known, in a glass plate manufacturing plant or the like, when manufactured glass plates are shipped, a package of glass plates is manufactured. This package includes a laminate in which a protective sheet (e.g., a mount) is interposed between a plurality of glass plates, and is packed by placing the laminate in a flat or vertical position on a tray or the like (see patent document 1 and the like). The packaged body is transported and transported to a glass product manufacturing plant or the like.

As an example of a method of conveying the package, patent document 2 (0024 of the document) discloses that at least one of a land conveyance means, an offshore conveyance means, and an air conveyance means is used.

Disclosure of Invention

Problems to be solved by the invention

However, in the method for conveying the package disclosed in patent document 2, it is not possible to appropriately cope with the vibration generated in the package during conveyance. That is, the magnitude of the vibration generated in the package body at the time of conveyance differs depending on the difference between the three conveyance methods described above. Therefore, in order to suppress the adverse effect of the vibration on the glass plate, it is important to set the respective conveyance distances to a good degree according to the difference in conveyance system. However, this document does not necessarily specify the relationship between the conveyance method and the conveyance distance.

Therefore, the present inventors have tried to transfer the package from a glass plate manufacturing plant to a glass product manufacturing plant (panel manufacturing plant) by various transfer methods such as land transfer, marine transfer, and the like, and used experiments to know the characteristics of the respective transfer methods. Specifically, experiments were attempted on how different the vibration and the defect generated in the glass sheet are according to the conveyance method and the conveyance distance. As a package in this case, a package is used which includes a laminate of a plurality of glass plates for flat panel displays and a mount sheet interposed therebetween, and which is packed with the laminate being mounted on a tray. In addition, experiments were attempted both when glass sheets were packed in a vertical posture (strictly speaking, an inclined posture) and when glass sheets were packed in a horizontal posture.

The present inventors have found from this experiment that if the conveyance distance of each conveyance system is not appropriate, the glass sheet reaching the panel manufacturing plant may be contaminated, and a disconnection failure may occur in the panel manufacturing process. The term "disconnection defect" as used herein means a state in which a wiring pattern (electrode pattern or the like) is disconnected due to dirt when the wiring pattern is formed on a glass plate. The present inventors also found that such a breakage failure is likely to occur in the same manner in both the case where the glass sheets are packed in a vertical posture and the case where the glass sheets are packed in a horizontal posture. The present inventors have also confirmed that the stain causing the disconnection failure is a stain generated by transferring foreign matter (resin component or the like) contained in the interleaving paper to the glass plate due to friction between the interleaving paper and the glass plate caused by vibration or the like during conveyance. As a result of the above experiments, the present inventors have found how to deal with the relationship between the conveyance manner and the conveyance distance of the package body so as to prevent such dirt from adhering to the glass plate.

From the above-described viewpoint, an object of the present invention is to reduce adhesion of dirt to a glass plate during conveyance by appropriately adjusting a relationship between a conveyance manner and a conveyance distance of a package including a laminate of a glass plate and a protective sheet.

Means for solving the problems

A first aspect of the present invention made to solve the above problems is a method for conveying a package including a laminate of a glass plate and a protective sheet, the method for conveying the package comprising: a first conveying process based on motor vehicle conveying; and a second conveying step of setting the conveying distance in the first conveying step to be 400km or less based on at least one selected from water conveyance, air conveyance, and rail conveyance. Here, the term "water transportation" means offshore transportation, transportation in a river, transportation in a canal, or transportation in which these are appropriately combined.

According to this configuration, the package body is conveyed in two groups. In the description of the characteristics of the grouping, the transportation on the road includes the vehicle transportation and the rail transportation, but among them, the vehicle transportation belongs to the first transportation step, whereas the rail transportation belongs to the second transportation step. The second conveyance process is water conveyance and air conveyance. The reason why such grouping is performed is because, as a result of the experiments described above, the inventors have found that, in the case of vehicle transportation, the vibration generated in the package is much larger than in water transportation, air transportation, and railroad transportation, and the former can be clearly distinguished from the latter, if the transportation distance is the same. Therefore, in the above-described experiment, even if the transport distance by the water transport, the air transport, and the rail transport is made longer than the transport distance by the vehicle transport, the glass plate may be stained in the former and the glass plate may not be stained in the latter. As described above, the dirt is generated by transferring foreign matter such as a resin component contained in the mount of the protective sheet to the glass plate by the friction between the protective sheet and the glass plate caused by the vibration during conveyance. In view of the above, it is necessary to shorten the conveying distance by automobile conveyance in advance to such an extent that no dirt adheres to the glass plate, among the entire conveying distances of the package body from the glass plate manufacturing plant or the like as the shipment source to the glass product manufacturing plant or the like as the shipment destination. From such a viewpoint, the present inventors have found, based on the already described experimental results, that the conveying distance in the first conveying step by the automobile conveyance is set to 400km or less. In this way, the adhesion of dirt to the glass plate during the transportation of the vehicle, which most causes large vibration of the package body, can be reduced.

In the transport method, as the vehicle transport in the first transport step, an initial vehicle transport and a final vehicle transport may be performed, and the second transport step may be performed while the initial vehicle transport is performed to the final vehicle transport.

In this way, the package can be efficiently transported from the shipment source to the shipment destination by water, air, or rail transportation.

In the above conveyance method, the total of the conveyance distances in the first conveyance step and the second conveyance step may be 550km or more.

As described above, the transport distance by the vehicle transport is shortened to 400km or less, and the water transport, the air transport, and the railway transport are suitable for the long-distance transport. Therefore, even when the entire transport distance from the shipment source to the shipment destination is as long as 550km or more, the vibration generated in the package body can be sufficiently reduced during the entire transport process, and the adhesion of dirt to the glass plate can be appropriately reduced.

A second aspect of the present invention made to solve the above problems is a method for planning conveyance of a package including a laminate of a glass plate and a protective sheet, the method for planning conveyance of the package being characterized by dividing a conveyance schedule in a plan for conveyance of the package into: a first transportation scheme based on motor vehicle transportation; and a second transportation plan based on at least one selected from the group consisting of water transportation, air transportation, and railroad transportation, and the transportation plan planning method for the package includes: a first distance setting step of setting a transport distance in the first transport plan; a second distance setting step of setting a transport distance in the second transport plan; and a distance adjustment step of adjusting the transport distance set in the first distance setting step to be 400km or less.

With this configuration, the package body is conveyed in two groups when planning the conveyance of the package body. The operation and effect obtained by dividing the conveying method into two groups in this way are substantially the same as those in the case of the corresponding conveying method described above. In this configuration, the first distance setting step sets a transport distance by the transportation of the vehicle, and the second distance setting step sets a transport distance by at least one of the water transportation, the air transportation, and the railroad transportation. In this case, when the transport distance by the vehicle transport is set by the first distance setting step, the distance is adjusted to 400km or less by the distance adjusting step. Thus, the conveying distance for conveying the motor vehicle can be accurately set through the process of the week arrival.

In the transportation plan setting method, an initial vehicle transportation and a final vehicle transportation may be performed as the vehicle transportation in the first transportation plan, and the second transportation plan may be performed while the initial vehicle transportation is performed and the final vehicle transportation is performed, and in the first distance setting step, a total distance between a transportation distance based on the initial vehicle transportation and a transportation distance based on the final vehicle transportation may be calculated and set as the transportation distance in the first transportation plan.

In this configuration, the operational effect of performing the second transportation pattern while the vehicle is transported from the initial stage to the final stage is substantially the same as in the case of the corresponding transportation method described above. In this configuration, the first distance setting step calculates the total distance between the transport distance by the initial vehicle transport and the transport distance by the final vehicle transport. Thus, the total distance between the transport distances of the two is accurately determined so as to be 400km or less, and then set as the transport distance in the first transport plan.

In the above transportation plan planning method, the method may further include a total distance adjusting step of adjusting the total distance of the first transportation plan and the second transportation plan to be 550km or more.

In this way, as in the case described above, even when the entire transport distance from the shipment source to the shipment destination is as long as 550km or more, the vibration generated in the package body can be sufficiently reduced during the entire transport process, and the adhesion of dirt to the glass plate can be appropriately reduced. In this configuration, the total distance adjusting step performs processing for setting the total of the transport distance by the automobile transport and the transport distance by at least one of the water transport, the air transport, and the railroad transport to a week length of 550km or more.

Effects of the invention

According to the present invention, the relationship between the conveyance form and the conveyance distance of the package including the laminate of the glass plate and the protective sheet can be made appropriate, and the adhesion of dirt to the glass plate during conveyance can be reduced.

Detailed Description

Hereinafter, a method for conveying a package and a method for planning conveyance of a package according to an embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a schematic side view showing a package as an object to be conveyed according to the present invention. As shown in the drawing, the package 1 is a package including a laminate 4 in which a mount sheet (protective sheet) 3 is interposed between a plurality of glass plates 2, and the laminate 4 is mounted on a tray 5 and packaged. Here, the glass plate 2 included in the laminate 4 is used for a flat panel display such as a liquid crystal display, an organic EL display, or a plasma display.

The tray 5 includes: a base part 7 having an insertion opening 6 for inserting a fork or the like of a forklift; a support portion 8 for supporting a lower end portion of the stacked body 4; and a backrest 9 that supports the laminated body 4 from the back side. Each glass plate 2 of the laminated body 4 is held in a vertical posture (strictly speaking, an inclined posture) by the support portion 8 and the backrest portion 9. The stack 4 is fixed to the tray 5 by a plurality of (two in the drawing) binding tapes 10. The stacked body 4 is covered with the bag body 11, and the internal space of the bag body 11 is sealed. This prevents dust and the like from entering the internal space of bag 11 and adhering to laminate 4.

The package 1 is manufactured when the glass plate 2 is shipped in a glass plate manufacturing plant. The package 1 thus produced is transported to a panel manufacturing plant for manufacturing a flat panel display. In a panel manufacturing factory, the package 1 carried in is unpacked, the glass plate 2 is taken out, and a wiring pattern (for example, an electrode pattern) is formed on the glass plate 2. The wiring pattern has, for example, a line width of 3 to 5 μm and a line interval of 25 to 200 μm, and preferably a width of 3 to 5 μm and a line interval of 25 to 50 μm.

< method for conveying Package >

Fig. 2 is a schematic diagram for explaining a method of conveying a package according to an embodiment of the present invention. As shown in the figure, the conveying method divides a conveying step 12 of conveying the package 1 into: a first conveyance process 13 based on vehicle conveyance; and a second transportation step 14 based on at least one selected from the group consisting of offshore transportation, air transportation, and railroad transportation. The conveying distance in the first conveying step 13 is α km or less, specifically 400km or less. The transport distance in the first transport step 13 is preferably 350km or less, more preferably 300km or less, from the viewpoint of further reducing the disconnection defect and preventing the disconnection defect in the denser wiring pattern. The total of the transport distances in the first transport step 13 and the second transport step 14 is β km or more, specifically 550km or more, or 700km or more, or 850km or more. Here, the first conveying step 13 and the second conveying step 14 are not limited to being performed once, and may be performed a plurality of times while the package body 1 is conveyed from the glass plate manufacturing plant as the shipment source to the panel manufacturing plant as the shipment destination. Specifically, the first conveyance step 13 and the second conveyance step 14 may be performed once each, the first conveyance step 13, the second conveyance step 14, and the first conveyance step 13 may be performed once each in sequence, the first conveyance step 13, the second conveyance step 14, and the first conveyance step 13 may be performed twice or three times in sequence, or other modes are possible. The conveying step 12 may include a step of temporarily storing the package 1 in a warehouse or the like. The conveyance method is managed by a manager such as a glass plate manufacturer, a panel manufacturer, or a conveyance provider. In addition, the selection of the conveyance method and the setting of the conveyance distance in the conveyance method are performed by the manager before the package 1 is conveyed.

In this conveying method, the conveying method of the package 1 is divided into two groups. The description of the characteristics of the grouping includes vehicle transportation and rail transportation in the transportation on the road, but among them, vehicle transportation belongs to the first transportation step 13, and rail transportation belongs to the second transportation step 14. Further, the marine transportation and the air transportation belong to the second transportation process 14. The reason for this grouping is because: if the transport distance is the same, the vibration generated in the package 1 during the transportation by the motor vehicle is much larger than that during the marine transportation, the air transportation, and the railway transportation, and the former can be clearly distinguished from the latter. Therefore, in the case of the transportation by the automobile, the adhesion of the dirt to the glass plate 2 due to the vibration of the package body 1 becomes more remarkable than in the case of the other transportation methods. The dirt is generated by transferring foreign matters such as resin components contained in the interleaving paper 3 to the glass plate 2 by the friction between the interleaving paper 3 and the glass plate 2 caused by the vibration. In consideration of the above, the transport distance of the package body 1 from the glass plate manufacturing plant as the shipment source to the glass product manufacturing plant as the shipment destination, particularly the transport distance by the automobile transport, needs to be shortened to such a degree that the glass plate 2 does not adhere to the dirt. From this viewpoint, the transport distance in the first transport step 13 by the automobile transport is set to α km or less. This can reduce the adhesion of dirt to the glass plate 2 during the conveyance of the package body 1. In addition, the package body 1 generates much less vibration than in the case of marine transportation, air transportation, and railroad transportation, and is therefore suitable for long-distance transportation. From this viewpoint, the total of the transport distance during the transportation by the vehicle and the transport distance by at least one of the offshore transportation, the air transportation, and the railroad transportation is β km or more. Thus, even when the entire conveying distance is long, the adhesion of dirt to the glass plate 2 during the conveyance of the package body 1 can be efficiently reduced. All matters described herein are findings of the present inventors through experiments described later. The term "stain" as used herein means a stain which causes a disconnection failure when the wiring pattern described above is formed on the glass plate 2 (hereinafter, the same shall apply). The term "disconnection defect" means that, when the wiring pattern described above is formed on the surface of the glass plate 2 to which the "dirt" is attached, the wiring pattern is broken (hereinafter, the same applies) by chipping, deformation, or disconnection.

Examples

The present invention has been completed through experiments that have been carried out by the present inventors. Therefore, in this example, experiments that the present inventors have performed and experimental results are explained. First, as shown in fig. 1, a package 1 is produced in which a laminate 4 including glass plates 2 and interleaving paper 3 is packed in a state of being loaded on a tray 5. In this case, the glass plate 2 has a longitudinal length of 1300 to 2200mm, a lateral length of 1500 to 2600mm, and a thickness of 0.3 to 0.7 mm. The number of glass plates 2 in the laminate 4 is 100 to 500. Thereafter, the package 1 is transported by vehicle transportation by a truck (container car), marine transportation by a ship (container ship), air transportation by an aircraft (air container), and rail transportation by a rail vehicle (rail container), respectively. After the package body 1 was conveyed by the different conveyance distances in the respective conveyance methods, it was checked whether or not the above-described dirt was adhered to the glass plate 2. The surface particle analyzer was used for inspection. The examination results are shown in table 1 below. In table 1, a case where no dirt was attached is denoted as [. circleincircle ], a case where dirt was slightly attached but was not the cause of the yarn breakage failure is denoted as [. circleircle ], and a case where dirt was attached the cause of the yarn breakage failure is denoted as ×.

[ TABLE 1 ]

According to the above table 1, in the transportation of the automobile, the transport distance is 300km or less, the transport distance is marked "x", the transport distance is 350km or 400km, and the transport distance is 450km or more. As described above, the "α km or less" relating to the transport distance by the transportation of the vehicle is preferably 400km or less, more preferably 350km or less, and still more preferably 300km or less. Further, in the case of the marine transportation and the air transportation, there is no problem of adhesion of dirt to the glass plate 2 even if the transportation distance is 5000 km. Further, in the railway transportation, if the transportation distance is 2000km or more, adhesion of dirt to the glass plate 2 becomes a problem, and therefore, 1500km or less is preferable. From the experimental results, the "α km or less" relating to the transport distance by the automobile transport is preferably within a range of a distance in which the glass sheet 2 can be transported without adhering to dirt which causes the disconnection defect in the case where the wiring pattern is formed, strictly speaking, within a range of 400km or less. When the lower limit value of the transport distance is α 1km, α 1km can be, for example, 10km, 50km, or 100 km. Further, it is found from the experimental results that offshore transportation, air transportation, and railway transportation are suitable for long distance transportation as compared with automobile transportation. Therefore, when the total distance of the conveying distance in the first conveying step 13 and the conveying distance in the second conveying step 14 is unduly shortened, the advantage of the second conveying step 14 cannot be effectively utilized. Therefore, the present inventors repeatedly examined the minimum total distance, in other words, β km, which is an advantage of effectively utilizing the second conveying step 14, and found 550 km. When the upper limit value of the total distance is β 1km, and when β 1km is considered from table 1, it is appropriate to set β 1km to 1500km when the rail transport is selected in the second transport step 14. On the other hand, when the offshore transfer and the airborne transfer are selected in the second transfer step 14, the upper limit of β 1 does not exist.

Next, a first example and a second example, which are specific examples of the method of conveying the package of the present invention, will be described.

[ conveying method of package body: first example)

Fig. 3 is a flowchart showing a first example of a method of conveying a package. In the first example, as the vehicle transfer in the first transfer step 13, the initial vehicle transfer and the final vehicle transfer are performed. More specifically, the package body 1 carried out from the shipment source 15 (glass plate manufacturing plant) is first conveyed by initial conveyance by a vehicle in step S1. Thereafter, the package 1 is transported by any one of offshore transportation and aerial transportation in step S2. Then, the package 1 is transported by the final motor vehicle transportation in step S3, and is carried into the shipment destination 16 (panel manufacturing plant).

The automobile transportation is superior in convenience and advantageous in that it can realize rapid transportation because it can realize on-time transportation as compared with marine transportation and air transportation. However, since the package body 1 is subjected to large vibration during the transportation by the vehicle, the transportation by the vehicle is not suitable for a long distance. On the other hand, although offshore transportation and air transportation are poor in convenience and rapidity, the package 1 is suitable for long-distance transportation because of small vibration. Therefore, in the first example, when the package body 1 is carried out from the shipment source 15 and when the package body 1 is carried into the shipment destination 16, the initial vehicle transfer and the final vehicle transfer are performed, and between the two vehicle transfers, either the marine transfer or the air transfer is performed. Therefore, the respective advantages of the motor vehicle transportation and the offshore transportation or the aviation transportation can be effectively utilized.

Fig. 4 is a schematic diagram showing a method of conveying the first example. This figure illustrates a case where land B1 is separated from land B2 across sea a, and where shipment source 15 is present on land B1 and shipment destination 16 is present on land B2. In land B1, roads R1, R2, R3 are connected from the source 15 to three ports C, D, E, respectively. On the other hand, in land B2, roads R4, R5, R6 are connected from three ports F, G, H to shipment destinations 16, respectively. In this case, three ports C, D, E of land B1 are connected to three ports F, G, H of land B2 by sea routes J1, J2, J3, respectively. In addition, although there are roads and seaways, the description thereof is omitted here for convenience of explanation. In this situation, a pair of roads whose total distance is α 1km or more and α km or less is found out from among the total distance between the road R1 and the road R4, the total distance between the road R2 and the road R5, and the total distance between the road R3 and the road R6. In the illustration, the total distance between the road R1 and the road R4 is α 1km or more and α km or less. In addition, the total distance of the road R2 and the road R5 and the total distance of the road R3 and the road R6 both exceed α km. The distances of the seaways J1, J2, and J3 are each β km to β 1 km. Therefore, in this case, the road R1 on which the vehicle is transported in the initial stage, the sea road J1 on which the vehicle is transported at sea, and the road R4 on which the vehicle is transported in the final stage are used as the routes for transporting the package 1. Here, the ports C to H may be airports, and the seaways J1 to J3 are open ways in this case. In the above description, the term "road distance" means a distance along a road, in other words, a length of the road, and the term "sea road distance" means a distance along a sea road, in other words, a length of the sea road (the same applies hereinafter). The term "track distance" as described later also means a distance along a track, in other words, a length of the track.

[ conveying method of package body: second example)

Fig. 5 is a flowchart showing a second example of the conveying method of the package. The second example is different from the conveying method of the first example described above in that the rail conveying is performed in step S11 during the period from the initial vehicle conveyance in step S1 to the marine conveyance in step S2, and the rail conveying is performed in step S12 during the period from the marine conveyance in step S2 to the final vehicle conveyance in step S3. In this way, when the total distance transported by the vehicle exceeds α km, the total distance transported by the vehicle can be shortened to α 1km or more and α km or less by replacing the excess transport distance with the railway transport. In the figure, the railway transportation is performed at two places, but the railway transportation may be performed at only one place.

Fig. 6 is a schematic diagram showing a method of conveying the second example. This figure is a diagram obtained by modifying a route in which the total distance between a pair of roads exceeds α km, among the routes exemplified by the transmission method of the first example described above. That is, on land B1, a road R2 from the shipment source 15 is shortened, and the terminal 17 of the road R2 is connected to port D by a track T1 for railway transportation. On land B2, a road R6 to the shipment destination 16 is shortened, and the start end 18 of the road R6 is connected to the port H by a track T2 for railway transportation. Thus, the total distance between the road R2 and the road R5 and the total distance between the road R3 and the road R6 are both α 1km to α km. The total distance between the track T1 and the sea road J2 and the total distance between the track T2 and the sea road J3 are both β km to β 1 km. Therefore, in the illustrated example, in addition to the route constituted by the road R1, the sea road J1, and the road R4, the route constituted by the road R2, the track T1, the sea road J2, and the road R5, and the route constituted by the road R3, the sea road J3, the track T2, and the road R6 can be used as the route for conveying the package 1.

In this case, in either of the first and second examples of the method of conveying the package, the distance between each road, each sea road, each empty road, and, in some cases, each track (including the tracks other than the tracks illustrated in fig. 4 and 6) can be measured by drawing a map, or based on electronic data as map information. In addition, the distance of each road can be measured using vehicle navigation or the like in addition to the above. Further, it is preferable that data of the distance and position of each road, each sea road, each empty road, and, in some cases, each track is stored in the storage means in advance. The total distance between the pair of roads and at least one of the sea road, the empty road, and the track may be calculated by a control means (for example, a built-in computer program) based on the above-mentioned data stored in the storage means. Note that the calculation of the total distance and the total distance may be performed by calculation of an operator (e.g., a manager) without using a storage means or a control means.

[ method for preparing delivery plan for package ]

Fig. 7 is a schematic diagram for explaining a package conveyance plan planning method according to the embodiment of the present invention. As shown in the figure, the transportation plan planning method divides the transportation plan 20 in the transportation plan of the package 1 into a first transportation plan 21 based on the transportation by motor vehicles and a second transportation plan 22 based on at least one selected from the group consisting of the marine transportation, the air transportation, and the railroad transportation. The delivery plan making method includes: a first distance setting step 23 of setting a transport distance in the first transport mode 21; a second distance setting step 24 of setting the transport distance in the second transport pattern 22; and a distance adjusting step 25 of adjusting the distance set in the first distance setting step 23 so as to be α 1km or more and α km or less. The transportation plan preparation method further includes a total distance adjustment step 26 of adjusting the transportation distances in the first transportation plan 21 and the second transportation plan 22 so that the total of the transportation distances is β km to β 1 km. Here, the first conveyance route 21 and the second conveyance route 22 are not necessarily used only once, but may be used a plurality of times, during the conveyance of the package 1 from the shipment source 15 to the shipment destination 16.

In this transportation planning method, the transportation modes of the package 1 are also divided into two groups. The characteristics of the grouping and the reason for performing the grouping are the same as those of the above-described package conveying method. The reason why the adhesion of the dirt to the glass plate 2 can be reduced is the same as that described above in the description of the conveying method for the package body. According to this transportation plan preparation method, a transportation distance by vehicle transportation is set in the first distance setting step 23, and a transportation distance by at least one of sea transportation, air transportation, and railroad transportation is set in the second distance setting step 24. In this case, when the transport distance by the vehicle transport is set in the first distance setting step 23, the distance is adjusted so that the distance is α 1km or more and α km or less in the distance adjusting step 25. Thus, the distance of the road for carrying the vehicle can be accurately obtained through the processing of the week. Then, according to this method of planning a conveyance plan, the total distance adjustment step 26 adjusts the total conveyance distance in the first conveyance route 21 and the second conveyance route 22 so as to be β km or more and β 1km or less. In this way, the sum of the distance of the road and the distance of at least one of the sea road, the air and the track can be accurately obtained by the processing of the surrounding. Therefore, the adhesion of dirt to the glass plate 2 can be further reliably reduced.

Next, a first example and a second example, which are specific examples of the method for planning the conveyance of the package body according to the present invention, will be described.

[ method for planning delivery of package: first example)

Fig. 8 is a flowchart showing a first example of a package conveyance planning method. In the first example, as the vehicle transfer in the first transfer schedule 21, the initial vehicle transfer and the final vehicle transfer are performed. In this first example, as in the first example of the above-described conveying method, the package 1 is first conveyed by the initial vehicle conveyance in step S21, then conveyed by either the marine conveyance or the air conveyance in step S22, and then conveyed by the final vehicle conveyance in step S23 and carried into the shipment destination 16. In the first example, the total distance between the initial vehicle transfer and the final vehicle transfer is calculated and set in the first distance setting step 23. The total distance is adjusted to α 1km or more and α km or less by the distance adjusting step 25. In the second distance setting step 24, the distance is set to be either offshore transfer or airborne transfer. In the first example, the total of the total distance set in the first distance setting step 23 and the distance set in the second distance setting step 24 is adjusted to β km or more and β 1km or less in the total distance adjusting step 26.

Next, a description will be given of a first embodied transportation plan planning method. The first example is an example of drawing up a transportation plan based on the map information shown in fig. 4 described above. In the first example, when the distance to be transported by the vehicle is set in the first distance setting step 23, the distance adjustment step 25 performs adjustment so that the total distance between the distance of each road on land B1 and the distance of each road on land B2 shown in the figure is α 1km or more and α km or less. As a result of this adjustment, the link R1 and the link R4 are found as a scheme in which the total distance between the pair of links satisfies the requirement of α 1km or more and α km or less. In addition, although the second distance setting step 24 sets the distance of the sea route in the sea a, in this case, the total distance adjustment step 26 performs adjustment so that the total distance between the pair of roads and the distance of the sea route is β km or more and β 1km or less. As a result of this adjustment, roads R1, R4, and sea road J1 were found as a plan in which the total distance satisfied the requirement of β km or more and β 1km or less. The discovered roads R1, R4 and sea road J1 are adopted as the transportation plan of the transportation plan. Note that, since the total distance between the roads R2 and R5 and the roads R3 and R6 shown in the figure does not satisfy the requirement of α 1km or more and α km or less, the total distance does not depend on the distances between the sea roads J2 and J3, and is not adopted in the transportation plan.

[ method for planning delivery of package: second example)

Fig. 9 is a flowchart showing a second example of the package conveyance planning method. The second example is different from the transportation plan preparation method of the first example described above in that the rail transportation is performed in step S24 during the period from the initial vehicle transportation performed in step S21 to the marine transportation performed in step S22, and the rail transportation is performed in step S25 from the period from the marine transportation performed in step S22 to the final vehicle transportation performed in step S23. In the second example, as in the transportation plan planning method of the first example, the total distance between the initial vehicle transportation and the final vehicle transportation is calculated and set in the first distance setting step 23, but the total distance is adjusted to α 1km or more and α km or less in the distance adjusting step 25. In the second example, the total distance between the two railway transports and either the marine transport or the air transport is calculated and set in the second distance setting step 24. In the second example, the total of the total distance calculated in the first distance setting step 23 and the total distance calculated in the second distance setting step 24 is adjusted to β km or more and β 1km or less in the total distance adjusting step 26. The respective conveyance distances set in the first distance setting step 23 and the second distance setting step 24 after these adjustments are adopted as the conveyance plan of the conveyance plan. In the figure, the railway transportation is performed at two places, but the railway transportation may be performed at only one place.

Next, a second embodied transportation plan planning method will be described. The second example is an example in which a transportation plan is prepared based on the map information shown in fig. 6 described above. Here, the total distance between the distance from the shipment source 15 to the road R1 at the harbor C on land B1 shown in the figure and the distance from the harbor F to the road R4 at the shipment destination 16 on land B2 satisfies the requirement of α 1km or more and α km or less. In contrast, the total distance of the route from shipment source 15 to port D in land B1 and the distance of the route from port G to shipment destination 16 in land B2 exceeds α km. In this case, the total distance between the road R2 on which the vehicle is transported on the land B1 and the road R5 on which the vehicle is transported on the land B2 is adjusted to α 1km or more and α km or less by the distance adjusting step 25. As a result of this adjustment, a shortened road R2 in land B1 and a road R5 in land B2 were found, and a track T1 for railway transportation from the terminal end 17 of the road R2 to the port D in land B1 was found. Similarly, a road R3 from the shipment source 15 to the port E and a shortened road R6 from the land B2 in the land B1 were found, and a track T2 for railroad transportation from the port H to the start 18 of the road R6 in the land B2 was found. Here, the total distance between the road R2 and the road R5 and the total distance between the track T1 and the sea road J2 satisfy the requirement of β km to β 1 km. Similarly, the total distance between the road R3 and the road R6 and the total distance between the track T2 and the sea road J3 satisfy the requirement of β km to β 1 km. Thus, in the illustration, any one of the three paths from the shipment source 15 to the shipment destination 16 can be adopted as the transportation scheme of the transportation plan. In this case, in order to meet the demand for reducing the number of loading and unloading works of the package 1, it is preferable to adopt a route on which the railway transportation is not performed, in other words, a route constituted by the road R1, the sea road J1, and the road R4, as a transportation plan.

In this case, in either of the first and second examples of the package body transportation plan planning method, the distance between each road, each sea road, each empty road, and, in some cases, each track (including tracks other than the tracks illustrated in fig. 4 and 6) is measured by drawing a map, or is measured based on electronic data as map information. In addition, the distance of each road can be measured using vehicle navigation or the like in addition to the above. Further, it is preferable that data of the distance and position of each road, each sea road, each air, and, in some cases, each track is stored in the storage means in advance. The calculation and setting of the total distance between the pair of roads in the first distance setting step 23, the calculation and setting of the distance (total distance) between the sea road or the empty road and, in some cases, the track in the second distance setting step 24 may be performed by a control means (for example, a built-in computer program or the like) based on the above-mentioned data stored in the storage means, or may be performed by the calculation of an operator. The adjustment of the distance in the distance adjustment step 25 and the adjustment of the distance in the total distance adjustment step 26 may be performed by a control means (for example, a built-in computer program or the like) based on the above-described data stored in the storage means, or may be performed by calculation by an operator.

In the above embodiment, the present invention was applied to the case where the land B1 on which the shipment source 15 is located and the land B2 on which the shipment destination 16 is located are separated by the sea a, but the present invention can be similarly applied to the case where the shipment source 15 and the shipment destination 16 are present on the same land.

In the above embodiment, the offshore transfer during the water transfer has been described as an example, but the transfer in a river or the transfer in a canal, which is another water transfer, can be handled in the same manner as the offshore transfer. Therefore, instead of marine transportation, river transportation or canal transportation may be applied to the present invention as water transportation. Instead of marine transportation, transportation in a river, or transportation in a canal, which is obtained by appropriately combining marine transportation, transportation in a river, or transportation in a canal, may be applied to the present invention as water transportation.
