In this case, the management machine sets the cargo handling means used for performing the first cargo handling work or the second cargo handling work when handling the cargo as the second cargo handling quantity and product condition setting means. And a cargo handling command is distributed to the terminal corresponding to the selected cargo handling means. In this way, by setting the second condition for each product type in accordance with the weight of the load by the product condition setting means, each of the cargo handling means is set to the first load handling operation and the second load operation according to the weight of the load to be handled. It can be used evenly for performing the cargo handling work, and the efficiency of the cargo handling work can be increased.
[0013]
Further, in the present invention, the plurality of cargo handling means is composed of a first cargo handling means suitable for performing the first cargo handling work and a second cargo handling means suitable for performing the second cargo handling work. To do. If it does in this way, when the frequency | count of each work of the 1st cargo handling work and the 2nd cargo handling work is substantially equal, the management machine will be able to set the first to third conditions by the condition setting means. The first cargo handling means is selected as the cargo handling means for performing the first cargo handling work, and the second cargo handling means is selected as the cargo handling means for performing the second cargo handling work. A cargo handling instruction is distributed to terminals corresponding to the above. As a result, in order to perform the first cargo handling work, the first cargo handling means suitable for this work is used, and in order to perform the second cargo handling work, the second cargo handling means suitable for this work is used. It is possible to increase the efficiency of cargo handling work.
[0014]
On the other hand, in the past, when carrying out the second cargo handling work, a specific worker always handled the baggage manually, so when the quantity of individual cargo handling is large, the height of the cargo handling place is high, When the weight is heavy, there is a problem that it is difficult to perform manual work, the work efficiency is deteriorated, and a burden on a specific worker is increased. However, as described above, the first to third conditions can be set by the condition setting means according to the status of the cargo handling work, or the second condition can be set according to the weight of the load by the product condition setting means. The management machine selects not only the second cargo handling means but also the first cargo handling means as the cargo handling means for performing the second cargo handling work, and distributes the cargo handling command to the terminal corresponding to the selected cargo handling work. Therefore, the second cargo handling work can also be performed using the first cargo handling means, and even in the above three cases, the efficiency of the cargo handling work can be improved, and the operator It is possible to reduce the burden per person.

[0030]
In the screen Z1 shown in FIG. 5 (a), since the stock quantity of the warehousing destination is 0 and the warehousing quantity is 100, all the packages W to be warehousing are stored in the storage space 3 of the storage bin at a time. It is instructed. Note that the cargo W to be stored is transported into the warehouse 1 by transport means such as an automatic guided vehicle or a forklift while being placed on the pallet P. When this screen Z1 is displayed on the display unit 14 of the terminal 11 provided on the pallet forklift 10, the worker M1 who gets on the pallet forklift 10 operates the forklift 10 to enter the warehouse 100. After the entire pallet P is picked up by the fork with the pallet P, the pallet P is loaded in the storage space 3 of the shelf number with the fork, and the goods are collectively received. On the other hand, when the screen Z1 is displayed on the display unit 24 of the terminal 21 provided on the picking forklift 20, the worker M2 who gets on the picking forklift 20 should operate the forklift 20 to enter the warehouse. All 100 pieces of luggage W are picked up by the fork together with the pallet P and transported to the storage space 3 of the shelf number, and then stored in the storage space 3 in a lump. At this time, if the width of the passage 4 is wide enough to change the direction of the body of the picking forklift 20 as described above, the worker M2 changes the direction of the body of the forklift 20 to the storage space 3 in which the fork is the storage bin. After changing to face each other, the entire cargo W to be stored in the storage space 3 is stored together with the pallet P with a fork. On the other hand, if the width of the passage 4 is not widened as described above, the worker M2 raises and lowers the driver's seat together with the fork to the height of the storage space 3 of the shelf number, and then enters the storage space 3 An empty pallet Pa is placed, and all of the cargo W to be received that has been picked up with a fork is placed on the empty pallet Pa by hand. In the case where the screen Z1 is displayed on the display unit 24 of the terminal 21 of the picking forklift 20, the check box X5 shown in FIG. 3 is checked, and the warehousing command represented by the screen Z1 is sent from the management machine 31 to the terminal. It is generated by being distributed to 21.
[0031]
In the screen Z2 shown in FIG. 5 (b), since the stock quantity of the warehousing destination is 50 and the warehousing quantity is 8, it is possible to individually receive the luggage W to be warehousing in the storage space 3 of the storage bin. Is instructed. When this screen Z2 is displayed on the display unit 24 of the terminal 21 provided in the picking forklift 20, an operator M2 who gets on the picking forklift 20 operates the forklift 20 to enter the 8 An individual load W is picked up together with the pallet P by a fork and transported to the storage space 3 for the shelf number. Then, the operator M2 raises and lowers the driver's seat together with the fork to the height of the storage space 3 of the shelf number, and then loads each of the eight loads W to be stored on the pallet P in the storage space 3 with the fork. The goods are loaded and received individually by hand. On the other hand, when the screen Z2 is displayed on the display unit 14 of the terminal 11 provided in the pallet forklift 10, the worker M1 who gets on the pallet forklift 10 should operate the forklift 10 to enter the warehouse. Eight pieces of cargo W are picked up together with the pallet P with a fork, and once placed at the transfer position 5a of the floor surface 5, 50 pieces of the cargo W in the storage space 3 of the shelf number are loaded with the pallet P with a fork. Then, it is once lowered to the repositioning position 5a of the floor surface 5. Then, the worker M1 alone or in cooperation with the worker M3 at the repositioning position 5a, 50 pieces of the eight pieces of luggage W to be stored are removed from the storage space 3 of the storage bin 3 on the pallet P. After individually loading on the luggage W by hand, the pallet forklift 10 is operated to pick up the 58 pallets P together with the pallet P with the fork and put them into the storage space 3 of the shelf number. In the case where the screen Z2 is displayed on the display unit 14 of the terminal 11 of the pallet forklift 10, the check box X4 shown in FIG. 3 is checked, and the setting box B2 of the condition 2 is “7” or less. This occurs when a numeric value or a numerical value of “3” or less is input to the setting box B3 of the condition 3 and the warehousing command represented by the screen Z2 is distributed from the management device 31 to the terminal device 11.
[0032]
FIG. 6 is a flowchart showing a procedure in which the management machine 31 distributes a cargo handling command to the terminals 11 and 21, and shows processing executed by the control unit 32 (FIG. 2) of the management machine 31. In FIG. 6, when the operator OP inputs an instruction to enter / exit a predetermined package W to / from the management machine 31, the control unit 32 takes in an entry / exit instruction and information on the package W to be loaded / unloaded (step S <b> 1). The information about the package W includes the product code of the package W, the product name, and the storage / reception quantity, as well as the location of the storage space 3 at the storage source or storage destination of the package W and the inventory quantity of the package W at that position. That is. Next, the control unit 32 determines whether or not the picking forklift 20 is set for picking (step S2). At this time, if the check box X4 shown in FIG. 3 is checked, the picking forklift 20 is set for picking (step S2: YES). It is determined whether it is a batch loading / unloading operation for loading / unloading all the packages W or an individual loading / unloading operation for individually loading / unloading the packages W (step S3). At this time, when the luggage W in the predetermined storage space 3 of the storage shelf 2 is to be delivered, if the delivery quantity of the luggage W matches the inventory quantity of the luggage W in the storage space 3, the entire luggage W is removed. It is determined that the work is to be delivered in a lump, and if the delivery quantity is less than the inventory quantity, it is judged that the work is to individually deliver the parcel W. In addition, when the luggage W is stored in the predetermined storage space 3 of the storage shelf 2, if the inventory quantity of the luggage W in the storage space 3 is zero, the entire package W is stored in a batch. If the inventory quantity is not zero, it is determined that the work is to individually load the packages W.
[0033]
If it is determined in step S3 that the loading / unloading operation is a batch loading / unloading operation for loading / unloading all the packages W, the process moves to step S4, and the pallet is used as a loading / unloading means used for the loading / unloading operation. Forklift 10 is selected. Then, a loading / unloading instruction indicating the contents of loading / unloading work is distributed to the terminal 11 provided on the pallet forklift 10 (step S5), and the process is terminated. When the entry / exit command is distributed to the terminal 11 as described above, a screen representing the contents of the entry / exit command is displayed on the display unit 14 (FIG. 2) of the terminal 11. At this time, the screen displayed on the display unit 14 is a screen such as the screen Y1 shown in FIG. 4A in which the outgoing quantity and the stock quantity of the outgoing source coincide with each other, as shown in FIG. This is a screen such as the screen Z1 where the stock quantity of the storage destination is zero. For this reason, the worker M1 boarding the pallet forklift 10 operates the forklift 10 on the basis of the loading / unloading instruction displayed on the display unit 14, and as described above, the entire load W is loaded into the predetermined storage space 3. I / O in bulk.
[0034]
On the other hand, if it is determined in step S3 that the loading / unloading operation is an individual loading / unloading operation for individually loading / unloading the package W, the process proceeds to step S6, where the remaining inventory quantity of the package W at the unloading source or the loading destination is determined. Then, it is determined whether or not it is less than or equal to the set quantity set in the setting box B1 of the condition X1 shown in FIG. Here, if the remaining inventory quantity is equal to or less than the set quantity (step S6: YES), the pallet forklift 10 is selected as the handling means (step S4), and a loading / unloading command is issued to the terminal 11 provided on the pallet forklift 10. Distribute (step S5), and the process ends. On the other hand, if the remaining inventory quantity is larger than the set quantity in step S6 (step S6: NO), the picking delivery quantity or individual receipt quantity when individually loading and unloading each package W is shown in FIG. It is determined whether or not it is less than or equal to the set quantity set in the setting box B2 of the condition X2 shown in (Step S7). Here, if the picking delivery quantity or the individual receipt quantity is larger than the set quantity (step S7: NO), the pallet forklift 10 is selected as the handling means (step S4), and the pallet forklift 10 is entered into the terminal 11 provided. The delivery instruction is distributed (step S5), and the process is terminated. On the other hand, if the picking delivery quantity or the individual receipt quantity is equal to or less than the set quantity in step S7 (step S7: YES), the shelf number (height) of the storage space 3 of the delivery source or the receipt destination is continued. Then, it is determined whether or not the number of steps is less than or equal to the number set in the setting box B3 of the condition X3 shown in FIG. 3 (step S8). Here, if the number of shelves in the storage space 3 at the delivery source or destination is higher than the set number (step S8: NO), the pallet forklift 10 is selected as the handling means (step S4), and the pallet forklift 10 is provided. An entry / exit command is distributed to the terminal 11 (step S5), and the process is terminated. On the other hand, if the number of shelves in the storage space 3 of the warehousing source or the warehousing destination is equal to or less than the set number in step S8 (step S8: YES), the picking forklift 20 is selected as the handling means (step S9), An entry / exit command is distributed to the terminal 21 provided in the picking forklift 20 (step S10), and the process is terminated.
[0035]
As described above, when the loading / unloading command is delivered to the terminal 11 of the pallet forklift 10 in step S5 via at least one of steps S6, S7, and S8, a screen showing the contents of the loading / unloading command is displayed. It is displayed on the display unit 14 of the terminal 11. At this time, the screen displayed on the display unit 14 is a screen such as the screen Y2 shown in FIG. 4 (b), where the delivery quantity is smaller than the stock quantity of the delivery source, or the screen Z2 shown in FIG. 5 (b). This is a screen in which the stock quantity of the warehousing destination is not zero. Therefore, the worker M1 boarding the pallet forklift 10 operates the forklift 10 on the basis of the loading / unloading command, and loads / unloads the luggage W individually into / from the predetermined storage space 3. Further, as described above, when the loading / unloading command is delivered to the terminal 21 of the picking forklift 20 in step S10 via all of steps S6, S7, and S8, a screen showing the contents of the loading / unloading command is displayed. It is displayed on the display unit 24 of the terminal 21. At this time, the screen displayed on the display unit 24 is also a screen such as the screen Y2 shown in FIG. 4 (b) where the delivery quantity is smaller than the stock quantity of the delivery source, or the screen Z2 shown in FIG. 5 (b). This is a screen in which the stock quantity of the warehousing destination is not zero. Therefore, the worker M2 boarding the picking forklift 20 operates the forklift 20 on the basis of the loading / unloading command, and loads / unloads the luggage W individually into / from the predetermined storage space 3.
[0036]
If the check box X5 shown in FIG. 3 is checked in step S2, the picking forklift 20 is not set for picking (step S2: NO), and is set as a pallet forklift. Therefore, the process proceeds to step S4. In step S4, a pallet forklift is selected as the cargo handling means. At this time, since not only the forklift 10 but also the forklift 20 is set as a pallet forklift, the control unit 32, as described above, is a forklift located at a location closest to the delivery source or the entry source of the luggage W, A forklift corresponding to a terminal with a small number of delivery instructions is selected as a handling means. Then, the loading / unloading command is distributed to the terminal provided on the selected forklift (step S5), and the process is terminated. At this time, the loading / unloading instruction delivered to the terminal indicates the contents of the work for loading / unloading all the packages W in / from the predetermined storage space 3 or the operations for loading / unloading the packages W individually. ing. When a loading / unloading instruction is delivered to a terminal as described above, a screen representing the contents of the loading / unloading instruction is displayed on the display unit of the terminal, so an operator boarding the forklift provided with the terminal However, by operating the forklift based on the loading / unloading instruction, as described above, the entire baggage W is loaded / unloaded into / from the predetermined storage space 3 or the individual packages W are individually loaded / unloaded.
[0037]
As in the above procedure, the management machine 31 individually performs the batch loading / unloading work for loading / unloading all the packages W and the packages W individually based on the loading / unloading quantities of the packages W and the three conditions X1 to X3. Conventionally, a loading / unloading means for performing an individual loading / unloading operation is selected from the two forklifts 10 and 20, and a loading / unloading instruction is distributed to the terminals 11 and 21 corresponding to the selected forklifts 10 and 20. Thus, the cargo handling means for performing the batch loading / unloading work and the individual loading / unloading work are not fixed. For this reason, forklift usage condition setting in FIG. 3 is performed when, for example, the number of operations for individual loading / unloading operations is larger than the number of batch loading / unloading operations, or when the picking / unloading quantity for individual loading / unloading operations increases. On the screen X, increase the numerical value input to the setting box B1 or decrease the numerical value input to the setting boxes B2 and B3 to set each condition X1 to X3, so that the picking up and down can be performed Not only the forklift 20 but also the pallet forklift 10 can be used, and the efficiency of the loading / unloading work can be increased. In addition, for example, when the number of operations of batch entry / exit work and individual entry / exit work is substantially equal, the numerical value input to the setting box B1 is set to “0”, the numerical value input to the setting box B2 is increased, and further setting is performed. In order to perform batch loading / unloading work by setting each condition X1 to X3 by setting the numerical value to be input in the box B3 to “5”, the individual loading / unloading work is performed using the pallet forklift 10 suitable for this work. Therefore, the picking forklift 20 suitable for this work can be used, and the efficiency of the loading / unloading work can be increased. That is, according to the status of the loading / unloading work performed in the warehouse 1 such as the number of times of the batch loading / unloading work and the individual loading / unloading work and the loading / unloading quantity of the luggage W, each condition X1 to X1 on the forklift use condition setting screen X is displayed. By setting X3 respectively, the remaining inventory quantity of the shipment W or the delivery destination package W, the picking delivery quantity or individual receipt quantity, and the number of trays (height) of the storage space 3 of the delivery source or destination Accordingly, the forklifts 10 and 20 can be equally used to perform batch loading / unloading work and individual loading / unloading work, and the efficiency of loading / unloading work can be increased.
[0038]
In addition, conventionally, when performing individual loading / unloading work, a specific worker (a worker on a picking forklift) has always handled the baggage W manually. When the number of shelves in the storage space 3 at the delivery source or the delivery destination is high, there is a problem that it is difficult to perform manual work, the work efficiency is deteriorated, and the burden on a specific worker is increased. . However, since not only the picking forklift 20 but also the pallet forklift 10 can be used to perform the individual loading / unloading work as described above, the number of individual loading / unloading is large, or the number of shelves at the unloading source or loading destination is high. Even so, it is possible to increase the efficiency of the loading / unloading work, and to reduce the burden on each worker M1, M2. In addition, if the individual loading / unloading operation is performed using the pallet forklift 10 when the number of individual loading / unloading is large or the number of racks at the loading / unloading source or receiving destination is high, the storage space 3 of the loading / unloading destination or the receiving destination is used. A certain load W is picked up together with the pallet P by a fork, and once lowered to a repositioning position 5a on the floor 5, a load W to be unloaded by the worker M1 manually or a load W to be loaded at this position 5a. Since it is handled, the workability of the manual work performed by the worker M1 is improved, and the efficiency of the loading / unloading work can be further increased. Further, when the individual inventory work is performed using the pallet forklift 10 when the remaining inventory quantity of the cargo W at the delivery source or the delivery destination is small, the workability of the manual work performed by the worker M1 as described above is improved. In addition to the improvement, it is possible to quickly pick up the cargo W from the shipping source or load the cargo W to the receiving destination, and to further increase the efficiency of the loading / unloading work.
[0039]
Further, when the number of batch loading / unloading operations increases, the check box X5 is checked and the picking forklift 20 is collectively loaded by the management machine 31 by setting the picking forklift 20 to be handled as a pallet forklift. Since it is selected as a loading / unloading means for performing the unloading work and the loading / unloading instruction is distributed to the terminal 21 corresponding to the forklift 20, not only the pallet forklift 10 but also the picking is performed for performing the batch loading / unloading work. The forklift 20 can also be used, and the efficiency of the loading / unloading work can be increased.
[0040]
In the embodiment described above, an example in which the second condition in the present invention is set by inputting an arbitrary numerical value in the setting box B2 in the forklift use condition setting screen X regardless of the type of the goods W to be loaded / unloaded. However, instead of this, the second condition may be set for each type of luggage W to be loaded and unloaded. FIG. 7 is a diagram showing an embodiment in this case. In FIG. 7, T is a product type master table displayed on the display unit 34 of the management machine 31 and constitutes product type setting means in the present invention. Information for displaying the table T on the display unit 34 is stored in a predetermined area of the storage unit 33, and information input by operating the operation unit 35 to the table T is stored in a predetermined area of the storage unit 33. It is memorized at any time. T1 is a product type code that identifies the cargo W to be loaded and unloaded, T2 is a product name of the product W, and T3 is a load quantity of the product W loaded on one pallet P. T4 is a condition for selecting a loading / unloading means to be used for performing a loading / unloading operation according to the picking delivery quantity or the individual receipt quantity. This condition T4 is set for each type according to the weight of the luggage W. For example, as shown in FIG. 7, “Eraser”, which is a light weight baggage W, is input with a large quantity, and “Paper”, which is a heavy weight baggage W, is input with a small quantity, "And" ballpoint pen "are input with the same quantity, and a condition T4 is set for each.
[0041]
When the condition T4 is set in this way, when the package W is loaded / unloaded, the management machine 31 performs batch loading / unloading work and individual loading / unloading work based on the loading / unloading quantity of the baggage W and the condition T4. Is selected from the two forklifts 10 and 20. Specifically, for example, when the package W to be loaded / unloaded is a “pencil”, the management machine 31 has a picking / unloading quantity or an individual loading quantity for individually loading / unloading the luggage W with respect to a predetermined storage space 3. If it is 10 or less of the set quantity set in the condition T4, the picking forklift 20 is selected as the handling means, and if it is not 10 or less (that is, 11 or more), the pallet forklift is used as the handling means. 10 is selected. In addition to such a selection procedure, the management machine 31 is based on conditions X1 to X3 set on the forklift use condition setting screen X shown in FIG. 3 in addition to the loading / unloading quantity of the package W and the condition T4. The cargo handling means for performing the batch loading / unloading work and the individual loading / unloading work may be selected from the two forklifts 10 and 20. In this case, the management machine 31 adopts the condition T4 instead of the condition X2 set on the screen X in FIG. A cargo handling means is selected according to the procedure described with reference to FIG. 6 based on the in-and-out quantity, condition X1, condition T4, and condition X3. (In other words, the determination process in step S7 in FIG. 6 is replaced with a determination process of “Is the picking delivery quantity or individual receipt quantity equal to or less than the set quantity of the condition T4?”) If the package W is not set with the condition T4, the cargo handling means is selected according to the procedure described with reference to FIG. 6 based on the loading / unloading quantity of the package W, the condition X1, the condition X2, and the condition X3. When the cargo handling means for performing the batch loading / unloading work and the individual loading / unloading work is selected from the two forklifts 10 and 20 as described above, the management machine 31 selects the terminal 11 corresponding to the selected forklift 10 or 20, 21 to deliver the entry / exit instruction.
[0042]
As described above, the forklifts 10 and 20 can be used equally for performing batch loading / unloading work and individual loading / unloading work according to the weight of the loaded / unloaded cargo W, thereby improving the efficiency of the cargo handling work. Is possible. Further, conventionally, when performing individual loading / unloading work, a specific worker always handles the baggage W manually, so that it is difficult to perform manual work when the weight of the baggage W is heavy. There is a problem that work efficiency is deteriorated and a burden on a specific worker is increased. However, since not only the picking forklift 20 but also the pallet forklift 10 can be used to perform the individual loading / unloading work as described above, the efficiency of the loading / unloading work can be improved even when the weight of the load W is heavy. And the burden on each worker M1, M2 can be reduced. Further, when the loading / unloading work is performed using the pallet forklift 10 when the weight of the load W is heavy, the load W is handled at the transfer position 5a of the floor surface 5 as described above. This improves the work efficiency of manual work performed and improves the efficiency of loading and unloading work.
[0043]
In the above embodiment, the management machine 31 selects the cargo handling means for performing the loading / unloading work based on the loading / unloading quantity of the luggage W and the conditions X1 to X3. In addition to the quantity and the conditions X1 to X3, the cargo handling means may be selected based on the work amount of the loading / unloading work performed by the forklifts 10 and 20. The work amount is the cumulative number of times of each of the batch loading / unloading work and the individual loading / unloading work, and the cumulative loading / unloading quantity of the luggage W that is loaded / unloaded by the batch loading / unloading work and the individual loading / unloading work. . In the case described above, the work amount is calculated for each forklift 10, 20 by the control unit 32 of the management machine 31 after delivering the cargo handling command to the terminals 11, 21, and a predetermined area in the storage unit 33. To remember. Thus, the control part 32 which calculates work amount comprises the calculating means in this invention. FIG. 8 is a flowchart showing an embodiment in this case. In the figure, the same processes as those in the flowchart shown in FIG. In FIG. 8, when the operator OP inputs an instruction to enter / exit a predetermined parcel W to / from the management machine 31, the control unit 32 takes in the instruction for entrance / exit and information regarding the parcel W to be in / out (step S1). As described with reference to FIG. 6, the processing from step S2 is executed.
[0044]
At this time, if it is determined in step S3 that the work for loading / unloading the package W is a work for loading / unloading the entire package W, or the remaining inventory quantity of the package W at the unloading source or destination in step S6. Is less than or equal to the set quantity set in the condition X1 (step S6: YES), or in step S7, the picking delivery quantity or the individual receipt quantity is larger than the set quantity set in the condition X2 (step S7: NO), In step S8, when the number of shelves in the storage space 3 of the warehousing source or warehousing destination is higher than the set number of tiers set in the condition X3 (step S8: NO), the process proceeds to step S3a. In step S3a, the work amount of the loading / unloading work performed by each of the forklifts 10 and 20 is taken from the storage unit 33, and it is determined whether or not the pallet forklift 10 has more work than the picking forklift 20. (Step S3b). The judgment at this time was made by comparing the cumulative number of times of the collective loading / unloading work and the individual loading / unloading work performed by each of the forklifts 10 and 20, and the loading / unloading by the collective loading / unloading work and the individual loading / unloading work. This is done by comparing the cumulative loading / unloading quantity of the package W. For example, when the cumulative number of individual loading / unloading operations of the pallet forklift 10 is smaller than the cumulative number of individual loading / unloading operations of the picking forklift 20, or the cumulative loading / unloading amount of the individual loading / unloading operations of the pallet forklift 10 is If it is less than the cumulative loading / unloading quantity of the individual loading / unloading work of the picking forklift 20, it is determined that the pallet forklift 10 does not have a larger work volume than the picking forklift 20 (step S3b: NO). Transition. In step S4, the pallet forklift 10 is selected as a loading / unloading means used to perform the loading / unloading work, and a loading / unloading instruction indicating the contents of the loading / unloading work is distributed to the terminal 11 provided on the pallet forklift 10 (Step S5). When the loading / unloading instruction is distributed, the amount of loading / unloading work performed by each of the forklifts 10 and 20 is calculated (step S10a), stored in a predetermined area of the storage unit 33, and the process is terminated.
[0045]
On the other hand, in step S3b, the cumulative number of individual loading / unloading operations performed by the pallet forklift 10 and the cumulative loading / unloading amount are respectively the cumulative number of individual loading / unloading operations performed by the picking forklift 20 and the cumulative loading / unloading amount. If more, it is determined that the pallet forklift 10 has more work than the picking forklift 20 (step S3b: YES), and the process proceeds to step S9. In step S9, the picking forklift 20 is selected as the cargo handling means, and the loading / unloading command is distributed to the terminal 21 provided on the picking forklift 20 (step S10). When the loading / unloading command is distributed, the amount of loading / unloading work performed by each of the forklifts 10 and 20 is calculated as described above (step S10a), stored in a predetermined area of the storage unit 33, and the process is terminated. As described above, each of the remaining stock quantity of the cargo W of the delivery source or the delivery destination, the picking delivery quantity or the individual receipt quantity, and the number of racks (height) of the storage space 3 of the delivery source or the delivery destination, Depending on the amount of loading / unloading work performed by the forklifts 10 and 20, the forklifts 10 and 20 can be used more evenly to perform batch loading / unloading work and individual loading / unloading work. Can be raised.
[0046]
In the above embodiment, check boxes X4 and X5 are provided in the forklift use condition setting screen X in FIG. 3, and only the picking forklift 20 is used as a cargo handling means for handling all the cargo W in a lump, or the cargo. Although an example has been given in which an individual W can be set as a cargo handling means for individually handling, the pallet forklift 10 is similarly used as a cargo handling means for handling all the cargo W in a batch or It may be settable as a cargo handling means for handling cargo individually. FIG. 9 is a diagram showing an embodiment in this case. Xa shown in FIG. 9 is a forklift use condition setting screen displayed on the display unit 34 of the management machine 31.
