As a result, when the loading / unloading operation is performed at the same time, after the article W is transferred from the transfer cart 60 to the temporary storage shelf 40, the temporary storage shelf 20 is moved without moving the transfer cart 60. Therefore, there is an advantage that the article W can be transferred to the transfer carriage 60 and a quick loading / unloading operation can be performed.

  Each temporary storage shelf 40 has the same configuration as the temporary storage shelf 20. Then, the goods W from the storage shelf 10 are transferred to the temporary storage shelves 40 for delivery by the transfer cart 60, and the temporary storage shelves for delivery until the goods W are transferred to the lifting mechanism 50 for delivery. 40 is temporarily placed. When each temporary storage shelf 40 is configured exclusively for output, each temporary storage shelf 40 may be configured such that the article W can be transported only toward the output lifting mechanism 50.

  The unloading lifting mechanism unit 50 includes a column part 51 having the same configuration as the column part 31 and an unloading lifting / lowering part 52 having the same configuration as the warehousing lifting / transferring part 32. And the raising / lowering transfer part 52 for unloading is moved up and down so that it may reach each height position of the shelf 12 of each stage and the unloading conveyor 18. In addition, in the state where the lifting / lowering transfer unit 52 for delivery reaches the height position of any one of the steps, a plurality of (here, two, two in the following) placed on the two temporary storage shelves 40 for delivery. Article W to be described) is transferred in parallel to the lifting / lowering transfer unit 52 for delivery. Further, one or two articles W placed on the lifting / lowering transfer part 52 for delivery are transferred to the delivery conveyor 18 in a state where the lifting / lowering transfer part 52 for delivery reaches the height position of the delivery conveyor 18. It is configured to transfer.

  The unloading conveyor 18 is an unloading transport mechanism, and has the same configuration as the unloading conveyor 16 except that the articles are transported in a direction away from the storage shelf 10. Here, the unloading conveyor 18 passes from the other side of the unloading lifting mechanism 50 to the outside of the outer end of the storage shelf 10 through the lower position of the lowest shelf 12 of the storage shelf 10 on the other side. It is provided to reach the direction. The delivery conveyor 18 only needs to be provided along the shelf 12 and may be provided in the middle or upper level. Here, the delivery conveyor 18 is disposed so as to pass below the storage shelf 10 that is diagonally opposed to the storage shelf 10 on which the storage conveyor 16 is provided. Therefore, the position where the article W is carried into the automatic warehouse and the position where the article W is carried out from the automatic warehouse are located at end positions opposite to each other in the longitudinal direction of the storage shelf 10. The unloading conveyor 18 is configured to convey the article W transferred from the unloading lifting mechanism 50 toward the predetermined unloading location through the lower side of the storage shelf 10. In addition, if the operation | movement which transfers several articles W from the two temporary storage shelves 40 for delivery in parallel to the raising / lowering transfer part 52 for delivery is performed partially overlapping in time, the transfer operation | movement will be carried out. Can be shortened. Therefore, both operations should be performed at least partially overlapping in time.

  The transfer cart 60 is a part also called a dolly, and is configured to be able to transfer the article W between a plurality of shelves and the temporary storage shelves 20 and the temporary storage shelves 40 for delivery corresponding to the respective shelves. ing.

  In the warehousing operation, an article W received via the warehousing conveyor 16 is transferred from the warehousing elevating mechanism 30 to the storage shelf 10 via each temporary storage shelf 20 and each transfer carriage 60. This is an operation of warehousing W. When the article W is received, an identification code of the article W to be received is input via the input unit, or an article type such as a barcode reader provided in the storage conveyor 16 or the storage lifting mechanism unit 30. The identification code attached to the article W is read by the reading unit. When the article W is stored in the storage shelf 10, inventory information in which the type of the article W is associated with the storage position in the storage shelf 10 is generated and updated. The delivery operation is an operation for delivering the article W stored in the storage shelf 10 in accordance with a delivery command input through an input unit or the like. When the article W is delivered, the delivery position of the article W to be delivered is determined with reference to the inventory information. When the article W is delivered, the inventory information is updated assuming that the article W is not in stock. For this reason, it is grasped and managed as the presence / absence of stock at each storage position of the storage shelf 10 and the article W in stock.

  The warehousing operation will be described more specifically. First, after the warehousing operation is started, in step S1, the control unit 70 determines the warehousing position. Specifically, two goods W are set and the warehousing position is determined. The warehousing position is selected from the empty positions with reference to the inventory information. Here, when there is a stage having two or more vacant positions, two of the vacant positions in the stage may be selected with priority. If there is no stage having two or more vacant positions, it is preferable to select vacant positions of different stages.

  In the next step S2, the control unit 70 determines whether the warehousing position is in the same level. If the warehousing position is on the same level, the process proceeds to step S3. If the warehousing position is not on the same level, the process proceeds to step S8.

  In step S <b> 3, the control unit 70 gives a command to transfer the two articles W from the warehousing conveyor 16 to the warehousing lifting / lowering transfer unit 32. Thereby, the two articles | goods W are transferred from the conveyor 16 for warehousing toward the raising / lowering transfer part 32 for warehousing (refer FIG. 11).

  In the next step S4, the control unit 70 gives a command to move the warehousing lifting / lowering transfer unit 32 up and down toward the stage to which the warehousing position belongs. As a result, the warehousing elevating / lowering transfer part 32 rises toward the stage and reaches between the two temporary storage shelves 20 for warehousing in the stage (see FIG. 12).

  In the next step S5, the control unit 70 drives in the direction in which the article W is moved so as to be distributed outwardly with respect to the rollers 34 of the two divided transfer units 33 of the warehousing elevating transfer unit 32. A command is given to each of the two temporary storage shelves 20 for taking in the articles W. As a result, the two articles W on the warehousing elevating / transferring section 32 are distributed outwardly and transferred onto the two warehousing temporary storage shelves 20 (see FIG. 13).

  In next step S <b> 6, the control unit 70 gives a command to transfer the article W from the two temporary storage racks 20 for storage toward a predetermined storage position of the storage shelf 10. As a result, the transfer cart 60 sequentially moves the two articles W placed on the two temporary storage shelves 20 for storage toward a predetermined storage position. In the meantime, it is preferable to lower the warehousing elevating and transferring part 32 toward the height position of the warehousing conveyor 16.

  Thereafter, in step S7, the control unit 70 determines whether or not the warehousing is completed based on the presence or absence of the article W on the warehousing conveyor 16. When it is determined that the warehousing has not been completed, the process returns to step S1, and when it is determined that the warehousing has been completed, the warehousing operation is terminated.

  If it is determined in step S2 that the warehousing position is not in the same level, the process proceeds to step S8.

  In step S <b> 8, the control unit 70 gives a command to transfer the two articles W from the warehousing conveyor 16 to the warehousing lifting / lowering transfer unit 32. As a result, the two articles W are transferred from the warehousing conveyor 16 toward the warehousing lifting / lowering transfer section 32.

  In the next step S9, the control unit 70 gives a command to move the warehousing / moving part 32 up and down toward the stage to which one warehousing position belongs. Thereby, the warehousing elevating / lowering transfer unit 32 rises toward the corresponding stage.

  In the next step S10, the control unit 70 gives a drive command in the direction of moving the article W toward the outside to the roller 34 of one of the divided transfer units 33 of the warehousing transfer unit 32. A command is given to the corresponding temporary storage shelf 20 for taking in the article W. As a result, one article W on the warehousing elevating / lowering transfer unit 32 is transferred onto one corresponding temporary storage shelf 20 for warehousing.

  In the next step S11, the control unit 70 gives a command to move the warehousing / moving part 32 up and down toward the stage to which the other warehousing position belongs. Thereby, the warehousing elevating / lowering transfer unit 32 rises toward the corresponding stage.

  In the next step S12, the control unit 70 gives a drive command in the direction of moving the article W toward the outside to the roller 34 of the other divided transfer portion 33 of the warehousing lift transfer portion 32, and A command is given to the corresponding other temporary storage shelf 20 for taking in the article W. Thereby, the remaining one article W on the warehousing elevating / lowering transfer unit 32 is transferred onto the corresponding warehousing temporary storage shelf 20.

  In the next step S13, a command is given to transfer the article W from each temporary storage shelf 20 to each predetermined storage position of the storage shelf 10 in the above two stages. Thereby, in each stage, the transfer carriage 60 moves each article W placed on the temporary storage rack 20 for storage toward a predetermined storage position. In the meantime, it is preferable to lower the warehousing elevating and transferring part 32 toward the height position of the warehousing conveyor 16.

  If it is determined in step S2 that the storage position is not in the same stage, the articles W may be transferred one by one from the storage conveyor 16 to the storage lift mechanism 30.

  Then, it progresses to step S7 and performs the process similar to the above.

  As a result, the plurality of articles W received through the storage conveyor 16 are sequentially stored in the storage shelf 10.

  The delivery operation will be described more specifically. First, articles W to be delivered are input together with the order of delivery through an input unit or the like. Then, in step S21, the control unit 70 determines the delivery position. Specifically, based on the order of delivery, two articles W arranged in series are set and the delivery position is determined. The delivery position is determined based on the inventory position of the target article W with reference to the inventory information. Here, when the types of target articles W are scattered over a plurality of stages, it is preferable to select the take-out position so that the two articles W as a set belong to the same stage. If this is not possible, it is recommended to select a shipping position on a separate stage.

  In next step S22, the control unit 70 determines whether or not the delivery position is in the same stage. If the delivery position is on the same stage, the process proceeds to step S23, and if the delivery position is not on the same stage, the process proceeds to step S28.

  In step S23, the control unit 70 transfers the previous article W to the temporary storage shelf 40 for delivery at the downstream side in the delivery direction and the delivery order later, regardless of the storage position of the article W at this stage. A command is given so that the article W is transferred to the temporary storage shelf 40 on the upstream side in the outgoing direction. Then, according to the said instruction | command, the transfer cart 60 transfers each article | item W in the two delivery positions of the said stage to the two temporary storage shelves 40 for delivery. Here, the unloading conveyor 18 conveys the article W from one side of the unloading lifting mechanism 50 outward (refer to the conveyance direction f in the right direction in FIG. 14). Therefore, the transfer cart 60 transfers the article W (1) with the previous delivery order to the temporary delivery shelf 40 (the temporary delivery shelf 40 on the right side in FIG. 14) on the downstream side in the transport direction. In addition, the transfer cart 60 transfers the article W (1) with the previous output order to the output temporary storage shelf 40 on the downstream side in the conveyance direction (the temporary storage shelf 40 on the right side in FIG. 14). In addition, the transfer cart 60 transfers the article W (2) with the subsequent output order to the temporary storage rack 40 for delivery on the upstream side in the transport direction (the temporary storage rack 40 for delivery on the left side in FIG. 14). At this time, since the transfer cart 60 can transfer the article W to both of the two temporary storage shelves 40 for unloading, it can be transferred in the above order without any trouble. Note that the order of transferring the articles W (1) and W (2) may be first. As a result, when the two temporary storage shelves 40 for delivery are viewed in succession, the plurality of articles W (1) and W (2) are arranged in the delivery order specified in advance in the transport direction f of the delivery conveyor 18. Become. In addition, it is preferable to move the raising / lowering transfer part 52 for unloading to the said stage during this operation | movement.

  In the next step S24, the control unit 70 gives a drive command to the two temporary storage shelves 40 for storage so that the articles W are transferred to the upward / downward transfer part 52 for output, and the upward / downward transfer part for output. A drive command is given to 52 so that the article W from both outsides is taken into itself. Thereby, the two articles W on the two temporary storage shelves 40 for unloading are simultaneously transferred in parallel to the lifting / lowering transfer unit 52 for unloading (see FIG. 15).

  In the next step S <b> 25, the control unit 70 gives a command to move the lifting / lowering transfer unit 52 to the position of the shipping conveyor 18. As a result, the lifting / lowering transfer unit 52 for unloading descends to the position of the unloading conveyor 18 (see FIG. 16).

  In next step S <b> 26, the control unit 70 gives a command to transfer the two articles W continuously from the lifting / lowering transfer unit 52 for shipping toward the shipping conveyor 18. Thereby, the two articles W on the lifting / lowering transfer unit 52 for unloading are transferred to the unloading conveyor 18 in succession. And the delivery conveyor 18 conveys the article W toward the outside. The articles W are arranged in the order of delivery in the state where they are transferred from the lifting / lowering transfer unit 52 for delivery to the delivery conveyor 18. For this reason, the articles W are conveyed to the outside through the delivery conveyor 18 in a state where they are arranged in a desired delivery order.

  Thereafter, in step S27, the control unit 70 determines whether or not the delivery is completed based on the delivery command. If it is determined that the exit has not been completed, the process returns to step S21. If it is determined that the exit has been completed, the exit operation is terminated.

  If the delivery position is not in the same level in step S22, the process proceeds to step S28.

  In step S <b> 28, the control unit 70 gives a command to move the one article W to one temporary storage shelf 40 in the stage to which the one article W belongs. Thereby, in the said stage, the transfer trolley | bogie 60 moves the articles | goods W of a predetermined storage position to the temporary storage shelf 40 for one delivery. During this operation, it is preferable to move the lifting / lowering transfer part 52 for lifting up and down to the position of the stage.

  In the next step S29, the control unit 70 gives a command to transfer the one article W from the temporary storage shelf 40 to the output lifting / lowering transfer unit 52 in the above stage. Thereby, one article W is transferred from one temporary storage shelf 40 to the outgoing elevator transfer part 52.

  In the next step S30, the control unit 70 gives a command to move the other one article W to the other temporary storage shelf 40 in another stage to which the other one article W belongs. Thereby, in the said other stage, the transfer trolley | bogie 60 moves the goods W of a predetermined storage position to the other temporary storage shelf 40 for delivery.

  In the next step S29, the control unit 70 moves the lifting / lowering transfer unit 52 up and down to the other stage. In the other stage, the control unit 70 moves the other part from the temporary storage shelf 40 to the shipping lifting / lowering transfer part 52. A command is given to transfer one article W. As a result, the other one article W is transferred from the other temporary storage shelf 40 to the outgoing elevator transfer part 52, and the two articles W are placed on the outgoing elevator transfer part 52. Become.

  In the next step S <b> 32, the control unit 70 gives a command to move the lifting / lowering transfer unit 52 to the position of the shipping conveyor 18. As a result, the lifting / lowering transfer unit 52 for unloading descends to the position of the unloading conveyor 18.

  In next step S <b> 33, the control unit 70 gives a command to transfer two articles W continuously from the lifting / lowering transfer unit 52 for shipping toward the shipping conveyor 18. Thereby, the two articles W on the lifting / lowering transfer unit 52 for unloading are transferred to the unloading conveyor 18 in succession. And the delivery conveyor 18 conveys the article W toward the outside.

  If it is determined in step S22 that the delivery position is not on the same level, the articles W may be transferred one by one from the temporary delivery shelf 40 to the delivery conveyor 18.

  Thereafter, in step S27, it is determined whether or not the delivery has been completed in the same manner as described above.

  As a result, the plurality of articles W are sequentially delivered through the delivery conveyor 18.

  According to the automatic warehouse configured as described above, a plurality of articles W moved up and down by the warehousing elevating mechanism unit 30 are distributed to two temporary storage shelves 20 for warehousing in at least one of the plurality of tiers.
