Description

Method for conveying package and method for planning conveying package

Technical Field

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

Background

As is well known, a package of glass sheets is produced when the produced glass sheets are shipped in a glass sheet manufacturing factory or the like. The package body is formed by stacking a plurality of glass sheets with a protective sheet (for example, a backing paper) interposed therebetween, and stacking the stacked sheets in a flat or vertical position on a tray or the like, and packaging the stacked sheets (see patent document 1 and the like). The package is transported to a glass product manufacturing factory or the like.

As an example of a method for transporting the package, patent document 2 (see [0024 ]) discloses that at least one of land transportation means, sea transportation means, and air transportation means is used.

Disclosure of Invention

Problems to be solved by the invention

However, in the method for transporting a package as disclosed in patent document 2, vibration generated in the package during transportation cannot be appropriately handled. That is, the magnitude of the vibration generated in the package body during the conveyance is different depending on the three conveyance methods listed above. Therefore, in order to suppress the negative influence of the vibration on the glass sheet, it is important to set the respective conveyance distances to a good degree according to the difference in conveyance modes. However, this document does not clearly specify the relationship between the conveyance system and the conveyance distance in the past.

Accordingly, the present inventors have tried to transport the above-mentioned package from a glass plate manufacturing plant to a glass product manufacturing plant (panel manufacturing plant) by using various transport systems such as land transport and offshore transport, and have made experiments for knowing the characteristics of the respective transport systems. Specifically, experiments were attempted on how much vibration and defects generated in the glass sheet differ according to the conveyance method and the conveyance distance. As a packaging body in this case, a packaging body including a laminate of a plurality of glass sheets for a flat panel display and interleaving paper interposed therebetween, and a tray on which the laminate is mounted and packaged is used. Experiments were also attempted on both the case of packing the glass sheets in a vertical posture (strictly, an inclined posture) and the case of packing the glass sheets in a horizontal posture.

The present inventors have found from this experiment that if the conveyance distance of each conveyance system is not appropriate, dirt may adhere to the glass sheet reaching the panel manufacturing factory, and a failure may occur in the process of manufacturing the panel. 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 have found that the breakage failure may occur even when the glass sheet is packed in the vertical posture and when the glass sheet is packed in the horizontal posture. The inventors have also confirmed that the dirt which causes the breakage failure is a dirt which is caused by, for example, foreign matter (resin component or the like) contained in the interleaving paper being transferred to the glass plate by friction between the interleaving paper and the glass plate due to vibration or the like at the time of conveyance. Further, as a result of the above-described experiments, the present inventors found how to deal with the relationship between the conveyance mode of the package and the conveyance distance to avoid such dirt adhering to the glass plate.

In view of the above, an object of the present invention is to reduce adhesion of dirt to a glass sheet during conveyance by appropriately adjusting a relation between a conveyance mode and a conveyance distance of a package body including a laminate of the glass sheet and a protective sheet.

Means for solving the problems

A first aspect of the present invention, which has been made to solve the above-described problems, is a method for transporting a package including a laminate of a glass plate and a protective sheet, the method comprising: a first conveying process based on motor vehicle conveying; and a second conveying step of setting a conveying distance in the first conveying step to 400km or less based on at least one selected from water conveying, aviation conveying and railway conveying. Here, the above-mentioned water transportation means offshore transportation, transportation in a river, transportation in a canal, or transportation obtained by appropriately combining these.

According to this configuration, the conveyance system of the package is divided into two groups. If the characteristics of the packet are described, the transportation on the road includes the vehicle transportation and the railway transportation, but the vehicle transportation belongs to the first transportation step, and the railway transportation belongs to the second transportation step. Further, the water transport and the air transport belong to the second transport step. The reason why such grouping is performed is that the inventors have tried the above-described experiments, and found that, in the case of transporting a motor vehicle at the same transport distance, vibration generated in the package body is significantly larger than that of water transport, air transport, and railway transport, and the former can be clearly distinguished from the latter. Therefore, in the above-described experiment, even if the transport distance by the water transport, the air transport, and the railway transport is made longer than the transport distance by the vehicle transport, dirt adheres to the glass plate in the former, and dirt does not adhere to the glass plate in the latter. As described above, the dirt is a dirt produced by transferring a foreign matter such as a resin component contained in a backing paper of a protective sheet to a glass plate by friction between the protective sheet and the glass plate due to vibration during conveyance. In view of the above, it is necessary to shorten the conveying distance, particularly by the conveyance of the motor vehicle, in the total conveying distance from the glass plate manufacturing factory or the like as the shipment source to the glass product manufacturing factory or the like as the shipment destination, to such an extent that dirt does not adhere to the glass plate. From this point of view, the present inventors found that the transport distance in the first transport process by the motor vehicle transport was 400km or less based on the experimental results already described. In this way, the adhesion of dirt to the glass sheet during the transportation of the motor vehicle, which most greatly vibrates the package body, can be reduced.

In the conveying method, the first conveying step may be a vehicle conveying operation, in which an initial vehicle conveying operation and a final vehicle conveying operation are performed, and the second conveying step may be performed during a period from the initial vehicle conveying operation to the final vehicle conveying operation.

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

In the above conveying method, the total conveying distance in the first conveying step and the second conveying step may be 550km or more.

As described above, the transport distance by the motor vehicle transport is shortened to 400km or less, and the above-water transport, the aviation transport, and the railway transport are suitable for long-distance transport. Therefore, even when the total transport distance from the shipment source to the shipment destination is 550km or more, the vibration generated in the package 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, which has been made to solve the above-described problems, is a method for planning a conveyance plan of a package including a laminate of glass sheets and protective sheets, wherein the method for planning the conveyance plan of the package is characterized by dividing a conveyance plan of the package into: a first delivery profile based on vehicle delivery; and a second conveyance scheme based on at least one selected from the group consisting of water conveyance, air conveyance, and railway conveyance, and the conveyance planning method of the bale body includes: a first distance setting step of setting a conveyance distance in the first conveyance scheme; a second distance setting step of setting a conveying distance in the second conveying scheme; and a distance adjustment step of adjusting the transport distance set in the first distance setting step so as to be 400km or less.

According to this configuration, the conveyance modes are divided into two groups when the conveyance plan of the package is formulated. The effect obtained by dividing the transport system into two groups is substantially the same as in the case of the transport method described above. In this configuration, the first distance setting step sets a transport distance by the vehicle transport, and the second distance setting step sets a transport distance by at least one of the water transport, the aviation transport, and the railway transport. In this case, when the first distance setting step sets the transport distance by the vehicle transport, the distance is adjusted to 400km or less by the distance adjusting step. This enables the transport distance at the time of transporting the vehicle to be accurately set by the discretionary process.

In the conveyance plan planning method, the first conveyance plan may be configured to perform initial conveyance of the vehicle and final conveyance of the vehicle, and the second conveyance plan may be configured to perform the second conveyance plan during a period from the initial conveyance of the vehicle to the final conveyance of the vehicle, and the first distance setting step may be configured to calculate a total distance between a conveyance distance based on the initial conveyance of the vehicle and a conveyance distance based on the final conveyance of the vehicle, and set the total distance as the conveyance distance in the first conveyance plan.

In this configuration, the operational effect of the second conveying means during the period from the initial stage of the motor vehicle conveying to the final stage of the motor vehicle conveying is substantially the same as that of the above-described corresponding conveying method. In this configuration, the total distance between the transport distance by the initial vehicle transport and the transport distance by the final vehicle transport is calculated in the first distance setting step. Thus, the total distance between the two transport distances is accurately obtained so as to be 400km or less, and then the transport distance is set as the transport distance in the first transport scheme.

The conveyance plan planning method may further include a total distance adjustment step of adjusting the total distance of the first conveyance plan and the second conveyance plan so that the total distance is 550km or more.

As described above, even when the total transport distance from the shipment source to the shipment destination is 550km or longer, the vibration generated in the package 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 adjustment step is performed to set the total of the transport distance by the vehicle transport and the transport distance by at least one of the water transport, the aviation transport, and the railway transport to 550km or more.

Effects of the invention

According to the present invention, the relationship between the conveyance mode and the conveyance distance of the package body 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

The method for transporting a package and the method for planning a transport plan for a package according to an embodiment of the present invention will be described below with reference to the drawings.

Fig. 1 is a schematic side view showing a package body as a conveyance object according to the present invention. As shown in the figure, the package 1 is a package that includes a laminate 4 in which a plurality of glass sheets 2 are sandwiched by interleaving papers (protective sheets) 3, and is formed by loading the laminate 4 on a tray 5 and packaging. Here, the glass plate 2 included in the laminate 4 is used in combination 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 portion 7 having an insertion port 6 for inserting a fork of a forklift or the like; a support portion 8 for supporting a lower end portion of the laminated 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, an inclined posture) by the support portion 8 and the backrest portion 9. The stacked body 4 is fixed to the tray 5 by a plurality of (two in the illustrated example) strapping tapes 10. The laminate 4 is covered with the bag 11, and the internal space of the bag 11 is sealed. This prevents dust or the like from entering the internal space of the bag 11 and adhering to the laminate 4.

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

< method of transporting package >

Fig. 2 is a schematic view for explaining a method of conveying a package according to an embodiment of the present invention. As shown in the figure, this conveying method divides the conveying process 12 of conveying the package 1 into: a first conveying step 13 based on the conveyance of the motor vehicle; and a second transportation step 14 based on at least one selected from the group consisting of offshore transportation, aviation transportation, and railway transportation. The transport distance in the first transport step 13 is equal to or less than α km, specifically equal to or less than 400 km. 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 from the viewpoint of 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, 700km or more, or 850km or more. Here, the first conveying step 13 and the second conveying step 14 are not limited to one time, and may be performed a plurality of times during the period from the glass sheet manufacturing factory as the shipment source to the panel manufacturing factory as the shipment destination. Specifically, the first conveying step 13 and the second conveying step 14 may be performed once, the first conveying step 13, the second conveying step 14, and the first conveying step 13 may be performed once in sequence, or the first conveying step 13, the second conveying step 14, and the first conveying step 13 may be performed once, twice, or three times in sequence, or other means may be used. 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 sheet manufacturer, a panel manufacturer, or a conveyance manufacturer. In this conveying method, the selection of the conveying system and the setting of the conveying distance are performed by the manager before the package 1 is conveyed.

In this conveying method, the conveying system of the package 1 is divided into two groups. When the characteristics of the packet are described, the transportation in the land includes the vehicle transportation and the railway transportation, but the vehicle transportation belongs to the first transportation step 13, and the railway transportation belongs to the second transportation step 14. Further, the marine transport and the aviation transport belong to the second transport step 14. The reason for this grouping is because: if the transport distance is the same, the vibration generated in the package body 1 in the case of the vehicle transport is significantly larger than that in the marine transport, the aviation transport, and the railway transport, and the former can be clearly distinguished from the latter. Therefore, in the case of the conveyance of the motor vehicle, the adhesion of dirt to the glass plate 2 due to the vibration of the package body 1 becomes remarkable as compared with other conveyance methods. This dirt is generated by transferring foreign matter such as a resin component contained in the interleaving paper 3 to the glass plate 2 by friction between the interleaving paper 3 and the glass plate 2 due to vibration. In view of the above, the conveyance distance, particularly by the conveyance of the motor vehicle, of the total conveyance distance from the glass sheet manufacturing factory as the shipment source to the packaging body 1 of the glass product manufacturing factory as the shipment destination needs to be shortened in advance to such an extent that dirt does not adhere to the glass sheet 2. From this viewpoint, the transport distance in the first transport step 13 by the vehicle transport is set to be α km or less. This can reduce the adhesion of dirt to the glass plate 2 during conveyance of the package 1. In addition, since vibration generated in the package body 1 is much smaller than that in the motor vehicle transportation for the offshore transportation, the aviation transportation, and the railway transportation, the package body is suitable for long distance transportation. From this viewpoint, the total of the transport distance in the vehicle transport and the transport distance based on at least one of the offshore transport, the aviation transport, and the railway transport is set to be β km or more. Thus, even when the total conveying distance is long, the adhesion of dirt to the glass plate 2 during conveyance of the package 1 can be reduced efficiently. All matters described herein are findings obtained by the inventors through experiments described later. The term "dirt" as used herein means dirt (hereinafter, the same applies) which causes a breakage failure when the wiring pattern is formed on the glass plate 2. The term "disconnection defect" means that when the wiring pattern is formed on the surface of the glass plate 2 to which the "dirt" is attached, the wiring pattern is broken, deformed, or disconnected, and the wiring pattern is disconnected (hereinafter, the same applies).

Examples

The present invention has been completed by experiments conducted by the present inventors. Therefore, in this example, experiments and experimental results that the present inventors have performed will be described. First, as shown in fig. 1, a package 1 is produced in which a laminate 4 composed of glass sheets 2 and interleaving papers 3 is stacked on a tray 5. In this case, the glass plate 2 has a longitudinal length of 1300 to 2200mm, a transverse length of 1500 to 2600mm, and a thickness of 0.3 to 0.7mm. The number of glass sheets 2 in the laminate 4 is 100 to 500. The package 1 is then transported by vehicle transportation, marine transportation, aviation transportation, and railway transportation, respectively, where vehicle transportation means transportation by truck (container car), marine transportation means transportation by ship (container ship), aviation transportation means transportation by aircraft (aviation container), and railway transportation means transportation by railway vehicle (railway container). After the package 1 was conveyed by each conveying system at different conveying distances, it was checked whether or not the above-described dirt was adhered to the glass plate 2. The surface particle analyzer was used for the inspection. The inspection results are shown in table 1 below. In table 1, the case where no dirt is attached at all is marked as excellent, the case where dirt is slightly attached but dirt which is not a cause of a wire breakage failure is marked as o, and the case where dirt which is a cause of a wire breakage failure is attached is marked as x.

[ Table 1 ]

According to Table 1, the excellent mark is given when the transport distance is 300km or less during the transport of the motor vehicle, marked as o for 350km and 400km, marked as x for 450km or more. As a result of the experiment, as described above, "α km or less" is preferably 400km or less, more preferably 350km or less, and still more preferably 300km or less, with respect to the transport distance by the vehicle transport. In addition, in offshore transportation and aviation transportation, the problem of adhesion of dirt to the glass plate 2 does not occur even when the transportation distance is 5000 km. In addition, in the case of railway transportation, when the transportation distance is 2000km or more, adhesion of dirt to the glass plate 2 becomes a problem, and thus 1500km or less is preferable. Further, according to the experimental result, "αkm or less" related to the conveyance distance by the vehicle conveyance is preferably in the range of 400km or less, and the distance is preferably in the range of a distance that can be conveyed so as not to adhere to dirt that causes the disconnection failure when the wiring pattern is formed on the glass plate 2. When the lower limit value of the transport distance is set to α1km, the α1km may be, for example, 10km, 50km, or 100km. Further, according to the experimental results, it is known that offshore transportation, aeronautical transportation, and railway transportation are suitable for long distance transportation as compared with the transportation of motor vehicles. Therefore, if the total distance between the conveyance distance in the first conveyance step 13 and the conveyance distance in the second conveyance step 14 is shortened, the advantage of the second conveyance step 14 cannot be effectively utilized. Accordingly, as a result of repeated examinations, the inventors found 550km as a minimum total distance, in other words, β km, which is an advantage of enabling effective use of the second conveying step 14. When the upper limit value of the total distance is set to β1km, it is appropriate to set to 1500km when the railway transportation is selected in the second transportation step 14 when the β1km is examined based on table 1. On the other hand, in the case where offshore transportation and aeronautical transportation are selected in the second transportation step 14, the upper limit of β1 does not exist.

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

[ method of conveying package: first example ]

Fig. 3 is a flowchart showing a first example of a method of conveying a package. In the first example, the first conveyance step 13 is to perform initial conveyance of the vehicle and final conveyance of the vehicle. Specifically, the package 1 carried out from the shipment source 15 (glass sheet manufacturing factory) is first transported by initial vehicle transportation in step S1. Then, the package 1 is transported by either of the offshore transport and the aeronautical transport in step S2. Then, in step S3, the package 1 is transported by the final-stage vehicle transportation and carried into the shipment destination 16 (panel manufacturing factory).

Since the motor vehicle transport can achieve on-time transport as compared with the offshore transport and the aviation transport, it is excellent in convenience and advantageous in that rapid transport can be achieved. However, since the vibration generated by the package 1 is large, the motor vehicle transportation is not suitable for long distance transportation. On the other hand, marine transport and aeronautical transport are inferior in convenience and rapidity, but since vibration generated in the package body 1 is small, they are suitable for long-distance transport. In the first example, therefore, when the package 1 is carried out from the shipment source 15 and when the package 1 is carried in to the shipment destination 16, the initial vehicle conveyance and the final vehicle conveyance are performed, and either the marine conveyance or the aviation conveyance is performed between the two vehicle conveyances. Thus, the 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 the first example of the conveying method. The figure shows that land B1 is separated from land B2 by sea a, and that there is an shipment source 15 on land B1 and a shipment destination 16 on land B2. In land B1, roads R1, R2, R3 are respectively connected from shipment source 15 to three ports C, D, E. On the other hand, in land B2, roads R4, R5, R6 are respectively connected from three ports F, G, H to the shipment destination 16. 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 to this, roads and seaways exist, but the description thereof is omitted here for convenience of explanation. In this case, a pair of roads having a total distance of α1km or more and αkm or less is found from among the total distance of the road R1 and the road R4, the total distance of the road R2 and the road R5, and the total distance of the road R3 and the road R6. In the illustration, the total distance between the road R1 and the road R4 is equal to or greater than α1km and equal to or less than αkm. 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 exceed αkm. The distances between the sea routes J1, J2, J3 are all not less than βkm and not more than β1km. In this case, therefore, the road R1 on which the initial motor vehicle transport is performed, the sea road J1 on which the offshore transport is performed, and the road R4 on which the final motor vehicle transport is performed are used as paths on which the package 1 is transported. Here, the ports C to H may be airports, and in this case, the sea paths J1 to J3 become empty paths. In the above description, "distance of road" means distance along road, in other words, length of road, and "distance of sea" means distance along sea, in other words, length of sea (hereinafter, the same). The term "track distance" as used hereinafter also means the distance along the track, in other words, the length of the track.

[ method of conveying package: second example ]

Fig. 5 is a flowchart showing a second example of the conveying method of the package. The second example differs from the conveying method of the first example in that the railway conveyance is performed in step S11 from the initial vehicle conveyance in step S1 to either the offshore conveyance or the aviation conveyance in step S2, and in that the railway conveyance is performed in step S12 from either the offshore conveyance or the aviation conveyance in step S2 to the final vehicle conveyance in step S3. In this way, when the total distance by the vehicle transportation exceeds αkm, the total distance by the vehicle transportation can be shortened to be equal to or greater than α1km and equal to or less than αkm by replacing the exceeding transportation distance with the railway transportation. In the illustrated example, the rail transport is performed at two places, but the rail transport may be performed only at any place.

Fig. 6 is a schematic diagram showing the conveying method of the second example. The figure is a diagram obtained by modifying a route in which the total distance between a pair of roads exceeds αkm, among routes exemplified by the above-described conveying method of the first example. That is, in the land B1, the road R2 from the shipment source 15 is shortened, and the terminal 17 of the road R2 is connected to the port D by the rail T1 for railway transportation. In the land B2, the route R6 to the delivery destination 16 is shortened, and the start end 18 of the route R6 is connected to the port H by the 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 equal to or greater than α1km and equal to or less than αkm. The total distance between the track T1 and the sea J2 and the total distance between the track T2 and the sea J3 are both equal to or greater than βkm and equal to or less than β1km. Therefore, in the illustration, the path formed by the road R2, the track T1, the sea J2, and the road R5 and the path formed by the road R3, the sea J3, the track T2, and the road R6 can be used as paths for conveying the package 1, in addition to the path formed by the road R1, the sea J1, and the road R4.

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

[ method of planning delivery of package ]

Fig. 7 is a schematic diagram for explaining a method of planning a transportation of a package according to an embodiment of the present invention. As shown in the figure, the transportation plan planning method divides a transportation plan 20 in the transportation plan of the package 1 into a first transportation plan 21 based on motor vehicle transportation and a second transportation plan 22 based on at least one selected from offshore transportation, aviation transportation, and railway transportation. The transportation plan planning method includes: a first distance setting step 23 of setting a conveyance distance in the first conveyance scheme 21; a second distance setting step 24 of setting a conveyance distance in the second conveyance scheme 22; and a distance adjustment step 25 of adjusting the distance set in the first distance setting step 23 so that the distance is not less than α1km and not more than αkm. The conveyance plan planning method further includes a total distance adjustment step 26 of adjusting the total conveyance distance in the first conveyance plan 21 and the second conveyance plan 22 so that the total conveyance distance is not less than βkm and not more than β1km. Here, the first conveying means 21 and the second conveying means 22 are not necessarily used only once or may be used a plurality of times during the period of conveying the package 1 from the shipment source 15 to the shipment destination 16.

In this conveyance schedule planning method, the conveyance modes of the package 1 are also divided into two groups. The characteristics of the packet and the reason for the packet are the same as those of the above-described method for conveying the package. The reason why the adhesion of dirt to the glass plate 2 can be reduced is the same as that described in the above description of the method for conveying the package. According to this conveyance plan planning method, a conveyance distance by vehicle conveyance is set in the first distance setting step 23, and a conveyance distance by at least one of marine conveyance, aviation conveyance, and railway conveyance is set in the second distance setting step 24. In this case, when the first distance setting step 23 sets the transport distance by the vehicle transport, the distance adjustment step 25 adjusts the distance so that the distance is not less than α1km and not more than αkm. This allows the distance of the road for the transportation of the vehicle to be accurately determined by the round-robin processing. According to this conveyance plan planning method, in the total distance adjustment step 26, the total conveyance distance in the first conveyance plan 21 and the second conveyance plan 22 is adjusted so as to be equal to or greater than βkm and equal to or less than β1km. Thus, the total of the distance of the road and the distance of at least one of the sea, aviation, and orbit can be accurately obtained by the discretionary process. Thus, the adhesion of dirt to the glass plate 2 can be further reliably reduced.

Next, a first example and a second example of a specific example of the method for planning a transportation plan of a package according to the present invention will be described.

Fig. 8 is a flowchart showing a first example of the conveyance schedule planning method for the package. In this first example, as the vehicle conveyance in the first conveyance scheme 21, the initial vehicle conveyance and the final vehicle conveyance are performed. In the first example, as in the first example of the above-described conveying method, the package body 1 is first conveyed by the initial vehicle conveyance in step S21, then conveyed by either the offshore conveyance or the aviation 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 conveyance and the final vehicle conveyance is calculated and set in the first distance setting step 23. The total distance is adjusted to be not less than α1km and not more than αkm in the distance adjustment step 25. In the second distance setting step 24, the distance between the marine transport and the aviation transport is set. 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 be β km or more and β1km or less in the total distance adjusting step 26.

Next, a specific first example of the conveyance plan planning method will be described. The first example is an example of creating a conveyance plan based on the map information shown in fig. 4. In the first example, when the distance of the vehicle transportation is set in the first distance setting step 23, the distance adjustment step 25 adjusts the total distance between the distance of each road on the land B1 and the distance of each road on the land B2 shown in the figure so as to be equal to or greater than α1km and equal to or less than αkm. As a result of this adjustment, the road R1 and the road R4 are found as a means that the total distance between the pair of roads satisfies the requirement of α1km or more and αkm or less. In the second distance setting step 24, the distance between the sea roads in the sea a is set, but in this case, the total distance adjustment step 26 adjusts the total distance between the pair of roads and the distance between the sea roads so that the total distance is not less than βkm and not more than β1km. As a result of this adjustment, the road R1, the road R4, and the sea J1 were found as means for satisfying the requirement that the total distance be equal to or greater than βkm and equal to or less than β1km. The found roads R1, R4 and the sea road J1 are adopted as the transportation scheme of the transportation plan. The roads R2 and R5 and the roads R3 and R6 shown in the figure do not satisfy the requirement of α 1km or more and α km or less, and therefore, the distances from the roads J2 and J3 are not related to each other, and are not used in the transportation scheme of the transportation plan.

[ method of planning delivery of package: second example ]

Fig. 9 is a flowchart showing a second example of the conveyance schedule planning method of the package. The second example differs from the conveyance plan planning method of the first example in that the railway conveyance is performed in step S24 from the initial vehicle conveyance in step S21 to either the offshore conveyance or the aviation conveyance in step S22, and in that the railway conveyance is performed in step S25 from either the offshore conveyance or the aviation conveyance in step S22 to the final vehicle conveyance in step S23. In the second example, the total distance between the initial vehicle conveyance and the final vehicle conveyance is calculated and set in the first distance setting step 23 in the same manner as in the conveyance plan planning method of the first example, but the total distance is adjusted to be not less than α1km and not more than αkm in the distance adjusting step 25. In the second example, the total distance between the two railroad conveyances and either the offshore conveyances or the aviation conveyances is calculated and set in the second distance setting step 24. In this 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 be β km or more and β1km or less in the total distance adjusting step 26. After these adjustments, the transport distances set in the first distance setting step 23 and the second distance setting step 24 are used as transport schemes for transport plans. In the illustrated example, the rail transport is performed at two places, but the rail transport may be performed only at any place.

Next, a description will be given of a second embodiment of the conveyance plan planning method. This second example is an example in which a conveyance plan is created based on the map information shown in fig. 6, which has been described. Here, the total distance of the distance from the shipment source 15 to the road R1 at the port C in the land B1 and the distance from the port F to the road R4 at the shipment destination 16 in the land B2 shown in the figure satisfies the requirement of α1km to αkm. In contrast, the total distance of the path from the shipment source 15 to the port D in the land B1 and the path from the port G to the shipment destination 16 in the land B2 exceeds αkm. 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 be equal to or greater than α1km and equal to or less than αkm by the distance adjustment step 25. As a result of this adjustment, a shortened road R2 in the land B1 and a road R5 in the land B2 are found, and a track T1 in the land B1 for railway transportation from the terminal 17 of the road R2 to the port D is found. Similarly, the road R3 from the shipment source 15 to the port E on the land B1 and the shortened road R6 on the land B2 are found, and the track T2 from the port H to the start 18 of the road R6 on the land B2 is found for railroad transportation. Here, the total of the total distance between the road R2 and the road R5 and the total distance between the track T1 and the sea J2 satisfies the requirement of β km to β1km. Similarly, the sum of the total distance between the road R3 and the road R6 and the total distance between the track T2 and the sea J3 satisfies the requirement of β km to β1 km. Thus, in the illustration, any one of the three paths from the shipment source 15 to the shipment destination 16 can be employed as the conveyance scheme of the conveyance plan. In this case, in order to cope with the demand for reducing the number of times of the loading and unloading operations of the package 1, it is preferable to use a route not being transported by a railway, in other words, a route constituted by the road R1, the sea J1, and the road R4, as a transport plan.

In this case, in either of the first and second examples of the method for planning the conveyance schedule of the package, the distance between each road, each sea, each empty road, and each track (including tracks other than the tracks illustrated in fig. 4 and 6) is measured by drawing a map or based on electronic data as map information. The distance measurement for each road may be performed using vehicle navigation or the like, in addition to the above. The data of the distance and position of each road, each sea road, each aviation, and each track according to circumstances is preferably 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 between the sea or the empty road and the track (total distance) according to circumstances 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-described respective data stored in the storage means, or may be performed by 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 is applied to the case where the land B1 where the shipment source 15 is located and the land B2 where the shipment destination 16 is located are located across 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 located on the same land.

In the above embodiments, the offshore transportation in the water transportation has been described as an example, but the transportation in the river or the transportation in the canal, which is another water transportation, can be handled similarly to the offshore transportation. Thus, instead of the offshore transportation, transportation in a river or transportation in a canal may be applied to the present invention as the above-water transportation. Instead of the offshore transportation, the transportation obtained by appropriately combining the offshore transportation, the transportation in the river, and the transportation in the canal may be applied to the present invention as the above-water transportation.

In the above embodiment, the stacked body 4 of the package 1 mounted on the tray 5 is constituted by the plurality of glass plates 2 in the vertical posture and the interleaving paper 3 interposed between the glass plates 2, but the stacked body 4 may be constituted by the plurality of glass plates 2 in the horizontal posture and the interleaving paper 3 interposed between the glass plates 2. In addition, as the protective sheet, a foamed resin sheet may be used instead of the backing paper.
