At this time, the article 4 moved by the roller-driven conveyor 21 is blocked by a stopper or the like, and when the merging is completed, the movement of the blocked article 4 is resumed after a certain time to avoid collision between the articles 4 and the article. An interval is provided between the four.

  A bar code reader 71 is connected to the branching device 62, and it is memorized when a “passing command consisting of bar code data of a store” to be described later is input from the zone control unit 54, and is detected by the bar code reader 71. If the barcode and the data stored as the passage command match, this collection container 20 is passed, and if it does not match, it is branched to the detour 61 and "branch execution signal including barcode data of the collection container 20" Is output to the zone controller 54.

  The operation of each zone control unit 54 of the picking controller 51 in the second embodiment will be described below. The operations of the overall control unit 53 and the input drive unit 55 are the same as those in the first embodiment, and the description thereof is omitted.

  1. When picking data and a start signal are input from the overall control unit 53, it is confirmed whether or not to perform picking work on the collection container 20 of each store in each picking zone Z by using the picking data. Then, a passage command composed of the bar code data of the store is formed and outputted to the branching device 62.

  2. Next, picking data excluding picking data of the collection container 20 that passes through is formed, and the number of articles 4 picked from each article storage unit 6 and the quantity thereof are totaled by these picking data. Picking data consisting of “number of storage unit 6−product name−total counting amount” is formed, output to the printer 77 to issue a picking list, and then a drive start signal is output to the conveyor controller 81. The conveyor 67 is driven.

  3. Next, when a branch execution signal including the barcode data of the collection container 20 is input from the branch device 62, the picking data of the store of the barcode data is assigned in order from the input device 22 located upstream, and the five downstream devices When assigned to the first charging device 22, it is repeatedly allocated to the most upstream charging device 22.

8). Further, when a movement stop command signal or a movement resumption command signal is input from the making drive unit 55, it is transferred to the conveyor controller 81.
In this manner, the zone control unit 54 forms a passage command composed of the bar code data of the store, and forms picking data composed of “the number of the product storage unit 6−the product name−the total count” for each product 4. When the picking list is issued and the previously performed picking operation of the loading device 22 is completed, the loading preparation completion signal is reset by the loading end signal of the loading drive unit 55, that is, the loading device 22 has no article 4 The picking device 22 is made to execute the picking device 22 in order. Therefore, it is possible to transfer the article 4 to each input device 22 in advance. At the start of picking, picking operations are performed in the order of input device No. 1 → No. 2 → No. 3 → No. 4 → No.

The operation of the picking controller 51 configured as described above will be described together with the overall operation.
1. When order data is input from the management computer 52 to the overall control unit 53 of the picking controller 51, the overall control unit 53 assigns a barcode to the store and forms label data to be output to the label printer 41. Picking data (FIG. 7) for each picking zone Z is formed and set in each zone control unit 54.

  2. When the general control unit 53 receives a picking start command from the management computer 52, the general control unit 53 outputs a start command to the zone control unit 54, and each zone control unit 54 includes the bar code data of the store according to the picking data. A passage command is formed and output to the branching device 62.

  3. Each zone control unit 54 obtains the total number of articles 4 to be picked for each article storage unit 6 according to the picking data, outputs the total to the printer 77 as list data, and issues a picking list. The operator collects the articles 4 in advance on the collective delivery temporary storage table 75 using the picking list.

  4). Then, the overall control unit 53 outputs the label data to the label printer 41 at the timing when the articles 4 are collected on the collective delivery temporary storage table 75 in each picking zone Z, and issues a label to be attached to the collection container 20. The roller drive conveyor 21 is driven after a certain time. The zone controller 54 outputs a drive start command to the conveyor controller 81, and the conveyor controller 81 starts driving the U-shaped conveyor 67 with a lifter.

  5. When the roller drive conveyor 21 starts to move, the worker in the collection container input area C applies labels to the collection container 20 in the order output from the label printer 41, and inputs the labels to the conveyor 21 at intervals of the input device 22. To do.

  6). When the collection container 20 is actually conveyed by the conveyor 21, the branching device 62 determines whether or not the collection container 20 is branched or passed in the picking zone Z, and the branched collection container 20 is conveyed by the U-shaped conveyor 67. In the picking zone Z, the picking work by the zone controller 54 is performed as follows.

  I. Based on the picking data assigned to the input device 22 for which the previous input operation has been completed, the picking data is displayed on the collective display 76, and the total amount is displayed on the digital display 38 of the input indicator 37 of the input device 22 to be input. Display and turn on the lamp of the display / completion button 39.

  B. The operator inputs the goods displayed on the collective display 76 and the quantity of articles 4 into the input device 22 from the collective delivery temporary storage table 75, and the quantity of the input articles 4 is determined by the total amount of the digital display 37 of the input apparatus 22. Confirm and operate the display / completion button 39.

  C. When the zone control unit 54 confirms the operation signal of the display / completion button 39, the zone control unit 54 confirms that the loading of the article 4 into the loading device 22 is completed, sets a loading preparation signal, and prepares the loading drive unit 55 for loading. Output a signal.

  D. The loading drive unit 55 monitors the barcode read by the barcode reader 72 and confirms the barcode assigned to the store in advance, until the collection container 20 of this store passes below the loading device 22. When the input of the store preparation signal is confirmed, the cylinder device 33 is opened and closed for a certain time at that timing, and the transferred article 4 is put into the collection container 20. When the charging is completed, a charging end signal is output to the zone control unit 54. If the input of the store preparation signal cannot be confirmed by the timing, the U-shaped conveyor 67 is stopped, waits until the input preparation signal is input, and when the input is confirmed, the article 4 is put into the collection container 20, When the loading is completed, a loading completion signal is output to the zone controller 54, and the drive of the U-shaped conveyor 67 is resumed.

  E. When the zone control unit 54 inputs the loading end signal, the zone controller 54 assigns the next picking data to the loading device 22 based on the barcode data of the collection container 20 input from the branching device 62. The picking operation is started (return to the procedure a).

  By such control of the picking controller 51, when the collection container 20 of the store assigned to each input device 22 passes, the article 4 previously transferred to the input device 22 is input and the picking zone Z Every collection is done. In addition, when the article 4 is thrown into the collection container 20, the input device 22 is driven one by one as the collection container 20 moves.

Then, the transfer of the article 4 of the next picking data is started to the input device 22 whose input has been completed.
7). The collection container 20 that is directly branched without being branched by the branching device 62 is conveyed to the downstream picking zone Z by the roller drive conveyor 21.

8). Then, the articles 4 are put into the collection containers 20 of the respective stores in the three picking zones Z, collected, and sent to the downstream manual picking area D.
9. In the manual picking area D, according to the list of the articles 4 instructed in advance for each store, the worker collects fragile articles (for example, eggs) with respect to the collection container 20 that has been automatically picked and sent upstream. Manually and carefully.

In this way, the ordered article 4 is collected in the collection container 20 for each store.
As described above, according to the second embodiment, in each picking zone Z, the detour is based on the information identifying the collection container 20 detected by the barcode reader 71 provided upstream of each branch point. When it is determined whether or not the collection container 20 is to be detoured by 61, only the collection container 20 having the picking work is guided to the detour 61, and picking is performed using the input device 22 arranged in the detour 61. In the case of the collection container 20 that performs the work and does not have the picking work, it is moved to the downstream picking zone Z along the fixed route i without making a detour to the detour 61. Therefore, work efficiency can be improved.

  Further, according to the second embodiment, the article 4 to be thrown into the collection container 20 by the operator is transferred to the loading device 22, and the target collection container 20 is moved by the U-shaped conveyor 67.
