This is an operation for collecting the articles W contained in the container C3 into the assortment container C2. The control device H performs selection control to select the target container C1 that has been determined to have the largest work load for moving the articles W stored in the plurality of target containers C1 to another target container C1 as the packing container C2. Run. The selection control will be described below, but among the articles W housed in the target container C1, the article W having a prescribed volume (for example, 4000 mL) or more is set as the large article WL. The total volume of the articles W contained in the target container C1 is the total volume.

  As shown in the selection control flowchart of FIG. 12, in the selection control, the number of large articles WL (S1), the total volume (S2), the number of articles W (S3), the work type when the articles W are stored (S4). ), the one of the plurality of target containers C1 is selected as the packing container C2 (S6). In the present embodiment, the above conditions are described in the order of description of the number of large articles WL accommodated, the total volume, the number of articles W accommodated, and whether or not the operator M accommodates the articles W. One of the plurality of target containers C1 is selected as the assorting container C2 so that the priority becomes higher (S1 to S4). Then, when one target container C1 is not selected under these conditions, the target container C1 is selected based on the prescribed condition for selecting one target container C1 that is determined in advance (S5). The prescribed condition may be, for example, the condition that the automatic warehouse 34 is first stored.

  In the selection control, first, selection is made based on the number of large articles WL accommodated (S1). That is, in the selection control, the target container C1 having the largest number of large articles WL accommodated in the plurality of target containers C1 is selected as the packing container C2. For example, as shown in FIG. 8, when there are a target container C1 in which one large article WL is accommodated and a target container C1 in which no large article WL is accommodated as the target container C1, the large article WL is included. The target container C1 in which one is stored is selected as the packing container C2.

  In the selection control, when the number of large articles WL accommodated in the plurality of target containers C1 is the same, selection is performed based on the total volume (S2). That is, in the selection control, the target container C1 having the largest total volume is selected as the packing container C2 from the plurality of target containers C1. As shown in FIG. 9, as the target container C1, a target container C1 having a small total volume (for example, a target container C1 having a total volume of 3000 mL) and a target container C1 having a large total volume (for example, a target container C1 having a total volume of 4000 mL) , Is selected, the target container C1 having a large total volume is selected as the packing container C2.

  In the selection control, when the number and the total volume of the large articles WL accommodated in the plurality of target containers C1 are the same, the selection is performed based on the number of the articles W accommodated (S3). That is, in the selection control, the target container C1 having the largest number of articles W stored in the plurality of target containers C1 is selected as the packing container C2. As shown in FIG. 10, if there are target containers C1 containing three articles W and target containers C1 containing six articles W as the target containers C1, there are six target containers C1. The target container C1 containing the article W is selected as the packing container C2.

  In the selection control, in the case where the number of large articles WL accommodated, the total volume, and the number of articles W accommodated in the plurality of target containers C1 are the same, depending on the work type when the articles W are accommodated. Specifically, the selection is performed based on whether or not the worker M stores the article W (S4). That is, in the selection control, the plurality of target containers C1 include the target container C1 in which the article W is stored by the automatic picking device 31 and the target container C1 in which the worker M in the picking work unit A1 stores the article W. In this case, the target container C1 containing the article W by the worker M is selected as the packing container C2. By the way, in FIG. 11, the target container C1 (the collection container C on the left side in FIG. 11) in which the article W is stored by the automatic picking device 31 and the target in which the article M is stored by the worker M in the picking work unit A1. And container C1 (collection container C on the right side in FIG. 11).

  Further, the control device H executes the transport control for transporting the plurality of target containers C1 to the assembling work unit A3. In this transfer control, the automatic warehouse 34 and the downstream side transfer device 2 are controlled so that the plurality of target containers C1 are transferred to the load matching operation unit A3 in the order of the load container C2 and the take-out container C3.

Further, the control device H controls the fourth weight detection device 42 so that the weight of the packing container C2 at the fifth position P5 is detected by the fourth weight detection device 42. Further, the control device H controls the fourth reading device 44 so that the fourth reading device 44 reads the container identification information of the ejection container C3 conveyed to the fifth position P5. The control device H acquires the weight information stored in the storage unit 8 in association with the container identification information based on the container identification information of the ejection container C3 read by the fourth reading device 44.

  As shown in FIG. 7, the worker M performs the load matching operation of moving all the articles W contained in the takeout container C3 at the sixth position P6 to the load matching container C2 at the fifth position P5. In this way, when the worker M performs the packing operation, the operation of reading the article identification information of the article W to be moved is not performed. In other words, in the present embodiment, in the loading operation, all the one or more articles W contained in the take-out container C3 are collectively loaded without individually inspecting the articles W contained in the take-out container C3. The work of accommodating the combined container C2 is performed. Then, when carrying out the packing operation, if the articles W housed in the take-out container C3 are packed by the packing material 21, the articles W are moved to the packing container C2 in the packed state. Further, in the present embodiment, the buffer material 22 is accommodated in the collection container C after the control device H has acquired the weight information, and the weight information in the collection container C does not include the weight of the buffer material 22. Not not. Therefore, in the present embodiment, even if the buffer material 22 is accommodated in the extraction container C3, the buffer material 22 is not moved to the packing container C2. When the buffer material 22 is housed in the collection container C before the control device H acquires the weight information, the buffer material 22 housed in the take-out container C3 is moved to the packing container C2. The worker M moves the take-out container C3, which has not contained the articles W due to the packing operation, from the fifth position P5 onto the empty container transport device 43. Then, the worker M moves all of the articles W accommodated in the take-out container C3 to the loading container C2 and completes the loading work, and then operates the loading completion button (not shown).

In the control device H, the weight of the load container C2 detected by the fourth weight detection device 42 increases in accordance with the operation of the load completion button, according to the weight indicated by the weight information in the take-out container C3. Or not. That is, when the weight of the cargo container C2 detected by the fourth weight detection device 42 increases in accordance with the weight indicated by the weight information in the take-out container C3, it is determined that the cargo packing operation has been appropriately performed. In this case, the control device H conveys the loading container C2 at the fifth position P5 from the fifth position P5 and reads the container identification information of the loading container C2 by the fifth reading device 45 so that the loading container C2 is loaded. The carrier device 41 and the fifth reading device 45 are controlled. Then, the control device H stores the weight information of the packing container C2 and the container identification information of the packing container C2 in the storage unit 8 in a state of being associated with each other. On the other hand, when the weight of the packing container C2 detected by the fourth weight detection device 42 does not increase in accordance with the weight indicated by the weight information in the take-out container C3, the packing work is properly performed. It is determined that it has not been broken. In this case, a notifying device (not shown) that indicates that the load-matching work is not performed properly is activated.

  As described above, the control device H controls the weight of the article W in the take-out container C3 detected by the first weight detection device 14 and the third weight detection device 29 in the picking work part A1 and the fourth weight in the loading work part A3. Based on the weight of the articles W in the load container C2 detected by the weight detection device 42, it is determined whether the load operation is properly performed. Further, the control device H uses the weight indicated by the weight information as the weight of the article W in the takeout container C3 when determining whether or not the packing operation is appropriately performed in this way.
