Prints the barcode and issues the label with the barcode.

In addition, the seal controller 49 inputs the order number recorded in the RFID 34 from the RFID reader 42A disposed downstream of the label printer 50, and inputs the barcode read by the barcode reader 51. It is checked whether or not the user assigned to the order number and the bar code respectively match, and whether the label is adhered to the bag 27 of the corresponding collecting container 10 without error. If it is confirmed as an error, error data including the order number is output to the repacking controller 57 described later. In addition, when the inspection is defective, a label is attached to the opened bag 27, and when the bar code cannot be read, similarly, the repacking controller 57 outputs error data including the order number.

In this way, the first worker H inspects and, when the inspection is satisfactory, folds the bag 27 held on the collecting container 10, wraps the collected article 11, and the second worker H. Sticks the issued label to the collecting container 10 which is sequentially conveyed by the second straight transfer line 21B. In addition, when sealed by the label and conveyed downstream, it is checked whether the label adheres to the bag 27 without error.

"Repacking Area (E)"; In the repacking area E, as shown to FIG. 4, FIG. 8, FIG. 10, the collection container conveyed by the 1st pre-conveyor 53 in which the empty box 13 was piled up, and the conveyance line B was carried out. The second pre-conveyor 54 which delivers the collecting box 13 which resealed the sealed goods 11 (the goods finished goods 11) of (10), and the goods 11 in the goods container 10 A bar code reader 55 for reading a bar code of a label adhered to a cheap bag 27, a label printer 56 disposed at a downstream position of the second pre-conveyor 54 to issue a shipping label, and a computer computer. A packing controller 57 and an indicator (display screen) 58 for displaying data and the like output from the repacking controller 57 are provided. In the repacking area E, two workers are arranged.

The 1st worker H is arrange | positioned in the upstream position of the 2nd free conveyor 54, and draws the empty box 13 from the 1st free conveyor 53 onto the 2nd free conveyor 54, In this collecting box 13, a bag (27) which repacks the sealed article 11 (the finished article 11) of the collecting container 10 for each delivery direction and wraps the final article 11 to repack. The barcode of the label adhering to) is read by the barcode reader 55 and pushed to the downstream side. Replacement of the collecting box 13 according to the delivery direction can be judged by the lighting and the color of the lamp 38 of the second lamp unit 33 of the feeding indicator 26 attached to the collecting container 10. . That is, the lamp 38 of the second lamp unit 33 lights green at the front end of the delivery direction (head) and red at the end of the delivery direction, and turns off other than that, so that the cutout line of the delivery direction is displayed (details Will be described later).

Further, the second worker H attaches the shipping label issued from the label printer 56 to the collecting box 13 which has been repacked and pushed out to the downstream side, and executes the shipment. As a shipment operation, it piles up on the trolley | bogie for shipment, for example.

As shown in FIG. 10, the said repacking controller 57 is connected with the barcode reader 55, the label printer 56, and the display (display screen) 58, The barcode which the user had previously assigned When the shipping label data set by the printer is stored and the barcode of the label is read by the barcode reader 55, the shipping label data set by the barcode is retrieved, and the shipping label data is output to the label printer 56 for shipment. Issue a label. In addition, when error data including an order number is input from the seal controller 49, an indicator (display screen) 58 displays an alarm of an inspection defect or a labeling miss occurrence including the order number, and collects a box. The repacking to (13) is stopped.

In this way, the sealed article 11 in the repacking area E is repacked into the collecting box 13 and shipped.

"Bagging area F"; As shown in FIG. 4, in the bagging area F, the collection container 10 which was conveyed by the conveying line B from the repacking area E (the repacking of the article 11 was finished, and was empty). The bagging device 60 which performs bagging in the container 10 is provided, and the bag 27 is automatically caught by the container 25 by the bagging device 60. At this time, by forming a gap 41 between the side of the container 25 and the input indicator 26, the bag 27 is caught in the container 25 without any problem.

In the bagging area F, the order number is erased from the RFID 34 by the RFID writer 42B provided upstream of the bagging device 60, and the RFID writer 42B provided downstream of the bagging device 60. ), A new order number is recorded in the RFID 34.

Due to the overall configuration of the picking equipment, the collecting container 10 is not circulated by the conveying line B, and the collecting container 10 itself is not shipped, but the bagging area F is placed in the empty collecting container 10. In this case, the bag 27 is caught, a new order number is recorded on the RFID 34, and a collection of articles 11 stored in the storage line A is executed based on this order number, and the collection is performed. When this is completed, inspection is performed in the sealing area D, the bag 27 is folded and sealed small, and a label specifying the user is attached, and in the repacking area F, the sealed article 11 is sealed. Silver is refilled in the collecting box 13 for each delivery direction and shipped. The collecting container 10 in which the sealed finished article 11 is taken out and emptied is enclosed with a bag 27 in the bagging area F, and a new order number is recorded in the RFID 34, and the collection is executed.

In this way, all the collection containers 10 are recycled, reused many times a day, and a new order number is assigned every time. Thus, in order to circulate, it is meaningful to install the RFID 34 in the input indicator 26 and to automatically rewrite the order number.

Control configuration; The control structure of a picking installation is shown in FIG.

Then, data is transmitted and received with the radio 36 of each input indicator 26.

"Integration controller 62"; The integrated controller 62 is connected with an area controller 24 for each picking area P, a seal controller 49, a repacking controller 57, a communication controller 63, and a display switching controller 64. In addition, the first straight transfer line 21A, the second straight transfer line 21B, the first curve transfer line 21C, the second curve transfer line 21D, the bagging device 60, and the bagging The RFID writer 42B installed downstream of the device 60 (at the corresponding location in the second curve conveying line 21D), and downstream of the repacking area E and upstream of the bagging area F. The RFID writer 42B is connected.

In the integrated controller 62, the following data is set in advance.

· A unique barcode assigned to each registered user by delivery direction.

Arrangement data of the supplications 16 of the picking area P in which the articles 11 to be ordered are stored, respectively (data of the supplications 16 of the picking area P corresponding to each article 11).

The integrated controller 62 has the following functions.

(A) The start command and the end command of the job are output to the area controller 24, the sealing controller 49, the repacking controller 57, and the communication controller 63 for each picking area P.

(B) Start the first straight transfer line 21A, the second straight transfer line 21B, the first curve transfer line 21C, the second curve transfer line 21D, and the bagging device 60. And stop.

(C) an order from each individual user registered in advance {order: an example of goods request information from each classification unit; When receiving the singular or plural data consisting of the information specifying the article (for example, the article type, article name, article code, etc.) and the quantity (number) of the article}, as shown in Fig. 14, the order is registered in advance. In the order of the assigned users, consecutive order numbers (an example of unique code) are assigned to the user's order (or to the user, namely, the classification destination or the item request information of the classification destination), and the respective picking areas P are assigned. The quantity of the order (the quantity of picking) is recorded in each seeker 16, and picking data of the storage line A is formed. At this time, in the storage line A, when the picking in each user order is finished, the area / number where the picking ends is obtained and stored.

(D) The order number assigned to each user and the picking data (including the area number at which picking ends) of the formed storage line A are transferred to the area controller 24 of each picking area P. FIG. Output

(E) For each order number assigned to a user, the total number of articles 11 picked from the order data is obtained, and the total number of articles 11 of each order number is assigned to the order number assigned to the user and the user's delivery. The data is output to the display switching controller 64 together with the data on the side.

(F) The order number and barcode assigned to the user are output to the sealing controller 49 and the repacking controller 57.

(G) When the RFID 34 is detected by the RFID writer 42B installed downstream of the bagging device 60 (installed at the corresponding position in the second curve transfer line 21D), the order of the users registered in advance Thus, the order number assigned to the user's order is output to the RFID writer 42B so that the RFID 34 records the order number. As a result, an order number is assigned to the collecting container 10 in which the feeding indicator 26 is mounted.

In this way, when the integrated controller 62 starts and stops the lines 21A, 21B, 21C, and 21D and the bagging device 60, and an order (order) from each user is input, the storage line Picking data (picking data for each picking area P) of (A) is formed, and data such as an order number and the like are output to each controller.

"Display changeover controller 64"; As shown in FIG. 13, the RFID display 42A provided in the downstream end of the storage line A, and the communication controller 63 are connected to the display switching controller 64, and each order number differs beforehand. The total number of the articles 11, the order number assigned to the user, and the data on the delivery direction of the user are input from the integrated controller 62.

When the display switching controller 64 inputs the order number recorded in the RFID 34 by the RFID reader 42A, the display switching controller 64 obtains the user by the order number, and also obtains the total number of the articles 11. This user finds whether or not it is a front end of the delivery direction or not.

Then, the following data is output to the communication controller 63 and transmitted via the transceiver 65 and the antenna 43. On the other hand, in the sealing area D downstream of the storage line A, since the first worker H is located on the opposite side to the worker H of the storage line A and the conveying line B, the input indicator The data (display reverse command) for displaying the display in the reverse direction is output so that the display of the digital device (display screen) 32 in 26 becomes an easy-to-view direction.

· When the user is at the tip of the delivery side. The data which turns on the lamp 38 of the 2nd lamp part 33 with a cover 39B to "green" with an order number, and turns off the lamp 38 of the 1st lamp part 31, And data for causing the digital display 32 to display the total number of articles 11 in the reverse direction (an example of display reverse command).

・ When the delivery direction is neither end nor end… Along with the order number, the data of the second lamp portion 33 and the lamp 38 of the first lamp portion 31 are turned off, and the data for displaying the total number of the articles 11 in the reverse direction by the digital display 32. (Example of display reverse command).

· At the end of delivery The data which turns on the lamp 38 of the 2nd lamp part 33 with a cover 39B to "red" with an order number, and turns off the lamp 38 of the 1st lamp part 31, And data for causing the digital display 32 to display the total number of articles 11 in the reverse direction (an example of display reverse command).

When this data is received by the radio unit 36 of the input indicator 26, the indicator controller 35 confirms whether or not the received data has been sent to the user by the order number of the received data. According to the received data, the lamps 38 of the second lamp unit 33 and the first lamp unit 31 are turned on / off, and the digital display 32 displays the total number of articles 11 in the reverse direction.

Since the order number of the received data is that of the input indicator 26 which passed through the downstream end of the storage line A, the ramp of the second lamp unit 33 in the input indicator 26 which passed through the downstream end Numeral 38 turns green at the leading end and red at the ending, and turns off the lights elsewhere. The lamp 38 of the first lamp unit 31 is turned off. In addition, in the digital display 32, "total number" (total number of articles 11) is displayed in the reverse direction instead of the displayed "order number" (or "END").

As shown in Fig. 3A, the delivery direction is indicated by the color of the lamp 38 of the second lamp unit 33, and is collected in the collecting container 10 for inspection. The total number of articles 11 in the reverse direction, that is, the worker H arranged in the storage line A, is viewed by the first worker H in the sealed area D in which the conveying line B is located on the other side. In an easy direction, it is indicated by the digital indicator 32.

"Area controller 24"; As shown in FIG. 15, each area controller 24 is provided with the supplication indicator 19, the bay indicator 20, and the self-picking area P of the picking area | region (henceforth a self-picking area | region) P which is in charge. The tape switch 23 of the input area (corresponding) input area (corresponding input area, hereinafter referred to as self input area) (Z) immediately opposite to each other, and the upstream input area adjacent to the upstream of the self input area (Z) ( An RFID reader (reduced by an upstream area RFID reader) provided at the tape switch 23 of Z), the accumulating unit 22 at the lowermost part of the self-insertion area Z, and the upstream end of the upstream input area Z. 42A), an RFID reader (reduced by a self-area RFID reader) provided at an upstream end of the self-insertion area Z, 42A, and an upstream end of a downstream input area Z adjacent to the downstream in the self-injection area Z. The RFID reader (reduced by the downstream area RFID reader) 42A and the integrated controller 62 are connected.

In addition, in each area controller 24, a number for specifying the self-picking area P and the self-insertion area Z is set in advance, and the arrangement of the supplications 16 in the self-picking area P, and each The data (arrangement data) of the article 11 stored in the supplication 16 is set, and the self-picking area specified by the order controller assigned to the user from the integrated controller 62 and each order number. Data (picking data) of the article 11 taken out from each interrogator 16 of (P) is input.

"Control configuration of area controller 24"; The area controller 24 picks up the article 11 from the interceptor 16 of the self-picking area P with respect to the collecting container 10 conveyed by the 21 A of 1st straight conveyance lines. Take control of your work. The control block diagram of the area controller 24 is shown in FIG.

The area controller 24 stores whether or not the picking operation by the array data, the order number assigned to each user, the picking data (including the area number at which the picking ends), and the picking data is finished. Recorded in the picking memory 71 and the RFID 34 of the input indicator 26 attached to each of the up to six collecting containers 10 positioned (moving) upstream from the upstream in the upstream input zone Z. Self-area memory 72 in which the stored order number is stored, and the same order number of each of the maximum six storage containers 10 located downstream from the upstream in the self-insertion area Z is stored ( 73, a data processor 74 for storing the order number and picking data assigned to the respective users input from the integrated controller 62 into the picking memory 71, and the upstream area container detector 75; And the self region container detector 76, Flow region is configured as a pre-display control section 77 and, with the self-region preceding the display control unit 78, the picking control unit (79), and a front transfer permission control unit 80.

"Upstream region container detector 75"; When the upstream area container detector 75 inputs an order number from the upstream area RFID reader 42A, the upstream area container detection unit 75 stores the order number as an order number of the most upstream collecting container 10 in the upstream area memory 72. Then, the previously stored order number is sequentially moved downstream. When an order number is input from the self-area RFID reader 42A, the order number is deleted from the upstream area memory 72, and the previously stored order number is moved downstream.

"Self-region container detection part 76"; When the self area container detection unit 76 inputs an order number from the self area RFID reader 42A, the self area container detection unit 76 stores the order number in the self area memory 73 as the order number of the most upstream collecting container 10. The order number memorized before is moved downstream in order. When an order number is input from the downstream area RFID reader 42A, the order number is deleted from the self area memory 73, and the previously stored order number is sequentially moved downstream.

Thus, in the upstream area memory 72 and the self-region memory 73, the order number of the collector 10 located in the upstream input area Z and the self-insertion area Z from the upstream to the downstream is It is remembered and updated. Moreover, since the order number of the collection container 10 located in each input area Z is memorize | stored by input of the order number from the RFID reader 42A, the installation position of the RFID reader 42A is upstream. By moving to the side or the downstream side, the range of the input area Z can be varied, and as shown in FIG. 18 (b), the attachment position of the RFID reader 42A is placed downstream, and the plurality of containers (drawings) In this case, the range of the input area Z corresponding to each picking area P can be offset (moved) downstream. In this way, the upstream input area Z is offset to the downstream side and the self input area Z is offset to the downstream side, so that the worker H can execute the picking operation around the self picking area P. The distance to move becomes short, and it becomes possible to improve work efficiency.

"Self region preceding display control unit 78"; The self-region leading display control unit 78 checks the order number stored in the self-region memory 73, searches the picking memory 71 by each order number, and checks for the presence or absence of picking data (self-picking). Whether there is an article 11 picked up from the interrogator 16 of the area P and put into the collecting container 10 located in the self-insertion area Z; if the picking operation is finished, no picking data is considered To be obtained.

If there is picking data in the order number (if there is a picking operation), the order number is stored, and the order number (the collection container 10) which is the most downstream is selected as the order number (the collection container) to be picked up. After the determination, the number of the self-insertion area Z is added to the order number and output to the picking control unit 79. Moreover, the self-region lighting data which added the number of the self-insertion area Z and a lighting signal to other order numbers except the order number of the collection container 10 which is the object of picking operation is output to the communication controller 63. do. Based on this self area lighting data, the lamp 38 of the second lamp unit 33 is turned on (described later).

If there is no picking data in the order number (when there is no picking operation), the self numbering out data obtained by adding the number of the self-insertion area Z and the unlit signal to the order number is output to the communication controller 63. do. Further, when there is no picking data at all, a no picking data signal is output to the upstream area preceding display control section 77. On the basis of the self area extinguishing data, the lamp 38 of the second lamp unit 33 is turned off (described later).

"Upstream region preceding display control unit 77"; The upstream area preceding display control unit 77 confirms the order number stored in the upstream area memory 72, searches for the picking memory 71 by each order number, and has picking data (self-picking). Whether there is an article 11 picked up from the interrogator 16 of the area P and put into the collecting container 10 located in the upstream input area Z; if the picking operation is finished, no picking data is considered. To be obtained.

If there is picking data in the order number (if there is a picking operation), the order number is stored, and it is checked whether the pick-up pick-up signal is input from the self-region leading display control unit 78 subsequently. When the signal of no picking data is confirmed, the lowest order number (the collection container 10) is determined as the order number (the collection container) to be picked up, and the order number of the upstream input area Z is determined. The number (subtracted 1 from the number of the self-insertion area Z) is added to the picking control unit 79 and output.

Furthermore, the upstream area lighting data which added the number of the upstream input area | region Z and a lighting signal to other order numbers other than the order number of the collection container 10 target of this picking operation is output to the communication controller 63. do. If there is no picking data in the order number (no picking operation), the upstream area extinguishing data obtained by adding the number of the upstream input area Z and the extinguishing signal to the order number is output to the communication controller 63. do. The lamp 38 of the first lamp portion 31 is turned on based on the upstream region lighting data, and the lamp 38 of the first lamp portion 31 is turned off based on the upstream region lighting data. (Described below).

"Picking control unit 79"; When the picking control unit 79 inputs the order number of the collecting container 10 to be picked up from the self-region preceding display control unit 78 or the upstream region preceding display control unit 77, the picking control unit 79 picks by this order number. The picking data of the memory 71 is retrieved. Furthermore, the self area blinking data or the upstream area blinking data which adds the number of the self-insertion area Z or the number of the upstream input area Z, and a blinking signal to the input order number is output to the communication controller 63. do. The lamp 38 of the second lamp portion 33 blinks based on the self region blinking data, and the lamp 38 of the first lamp portion 31 blinks based on the upstream region blinking data. (Described below).

Subsequently, in accordance with the picking data of the collecting container 10 to be picked up, the petition indicator 19 displays the number of the supplication 16 to take out the article 11 and the quantity of the article 11 to be taken out. In addition, the bay indicator 20 informs the number of stages of the shelf 17 in which the interceptor 16 with which the article 11 is taken out is located. Then, the ejection of the article 11 from the supplication 16 is confirmed by the operation of the completion push button switch 19B of the supplication indicator 19, and the tape switch 23 (self) in the self-insertion area Z is displayed. When the article 11 is put into the collecting container 10 of the input area Z, or the tape switch 23 (the collecting container 10 of the upstream input area Z) of the upstream input area Z. By the operation of (11), the end of the picking operation to the collecting container 10 is confirmed. If confirmed, the picking data of the executed picking memory 71 is set as the end of the picking operation, the order number after the picking operation is finished is output to the front transfer permission control unit 80, and then the self-picking area is selected from the picking data. Check whether (P) is set in the picking end area.

In addition, when the self-picking area P is set in the picking end area, the area end extinguishing data obtained by adding an "END" (an example of display of "insertion of the article") display command to the order number and an unlit signal. Is output to the communication controller 63.

"Front transfer permission control unit 80"; The front transfer permission control unit 80 searches for picking data in the picking memory 71 by the lowest order number in the self-region memory 73 to confirm the presence or absence of a picking operation. At that time, the forward transfer permission signal is output to the lowest accumulation accumulator 22. In addition, when there is a picking operation, the picking control unit 79 waits until the order number after which the picking operation is completed is input, and from the self-insertion area Z, the collecting container 10 whose picking operation is not finished is downstream. When the order number is prevented from moving to the input area Z and the order number is inputted, it is checked whether or not this order number matches the lowest order number in the self-region memory 73, and if it matches, The downstream accumulation permission signal 22 is output to the downstream accumulator 22.

The communication controller 63 indicates the "self-order lighting data which added the order number to the number of the self-insertion area Z and the lighting signal" or "the order number to the self-injection area Z." Self-region off data plus number and extinction signal "or" END "display command to order number, and area end extinction data plus extinction signal" or "order number upstream input area ( Z) number and upstream area lighting data which added the lighting signal ", or" upstream area lighting data which added the number of upstream input area | region Z, and an unlit signal to the order number ", or" order number To the number of the self-insertion area Z and the flashing signal plus the self-area blinking data ", or" the number of the upstream input area Z to the order number and the upstream area flashing data plus the blinking signal ". If you enter, the transceiver 65 and the antenna Through me 43, a call is made.

When this data is received by the radio unit 36 of the input indicator 26, the indicator controller 35 confirms whether or not the received data has been sent to the user by the order number of the received data. According to the received data, as shown in Fig. 3A, the "order number" is displayed on the digital display 32, or when the end of area is off data, the "END" is replaced by the "order number". Is displayed on the digital display 32, and the lamp 38 of the second lamp unit 33 and the first lamp unit 31 is turned on / flashing / lighting out as follows. Further, it is assumed that red is lit when the number of the input areas Z is odd and green is lit when the even number is even.

Self-Area Lighting Data… The lamp 38 of the second lamp unit 33 is turned on.

Self area extinguished data or area end extinguished data. The lamp 38 of the second lamp unit 33 is turned off.

Self- Area Flashing Data The lamp 38 of the second lamp unit 33 blinks.

Upstream area lighting data The lamp 38 of the first lamp unit 31 is turned on.

Upstream area extinction data. The lamp 38 of the first lamp unit 31 is turned off.

Upstream area blinking data The lamp 38 of the first lamp unit 31 blinks.

In this way, the lamp 38 of the second lamp portion 33 of the feeding indicator 26 attached to the collecting container 10 located in the self-feeding zone Z is turned on / flashing / lighted out. It is displayed that it is the collection container 10 which is going to be picking-up, and it is displayed by blinking, and it is displayed now that it is the collection container 10 of the picking operation execution object, The article 11 in which the collecting container 10 located in the self-feeding area Z, which is displayed and attached with the feeding indicator 26 by the second lamp portion 33, is taken out of the self-picking area P. It appears whether it is the houseware container targeted for the input of).

In addition, the lamp 38 of the first lamp unit 31 of the feeding indicator 26 attached to the collecting container 10 located in the upstream feeding zone Z is turned on / flashing / turned off. It is displayed that it is the planned collection container 10, and by blinking, it is displayed now that it is the collection container 10 to which picking work execution object turns out, and it turns out that it is the collecting container 10 which is not the object of picking work, The collecting container 10 located in the upstream input area Z, to which the input indicator 26 is attached, of the article 11 taken out from the self-picking area P by the first lamp part 31. It is indicated whether or not it is a collecting container to be charged.

In addition, the state (lighting / flashing / off state) of the lamp 38 of the second lamp unit 33 of the input indicator 26 is controlled by the self-area preceding display control unit 78, and the first lamp unit The state of the lamp 38 in the 31 is controlled by the upstream region preceding display control section 77, whereby the collecting container 10 has been moved from the upstream input region Z to the downstream input region Z. At this time, the above state of the lamp unit 31 of the first lamp unit 31 and the second lamp unit 33 of the input indicator 26 is reviewed at the same time, so that the first lamp unit 31 and the second lamp unit Both of the above states of the lamp 38 in 33 are updated at the same time.

"Moving operation of the collection container 10 in the storage line A"; The movement of the collection container 10 for each input region Z by the configuration of the first straight transfer line 21A and the configuration of the area controller 24 is as follows.

a. In the input area Z, if there is an empty accumulation part 22, it fills up.

b. The movement beyond the input area Z is the area controller 24 of the corresponding self picking area P, which is unconditionally opposed to the self input area Z, when the collecting container 10 is not a picking operation object. ), The forward transfer permission signal is outputted, and moves when the empty accumulation section 22 is generated upstream of the downstream input area Z.

c. The movement passing to the input area Z is when the picking container 10A that is the picking operation target, until the front transfer permission signal is output from the area controller 24 of the input area Z, that is, the picking operation is to be completed. Until the empty accumulator 22 has been generated upstream of the downstream input region Z, it does not move and stops, so that the lowermost collection container 10 in which the picking operation is not finished is placed in the downstream input region ( The movement to Z) is prevented, and by the output of the forward feed permission signal, the first movement to the downstream injection zone Z is performed (the empty accumulation section 22 is generated upstream of the downstream injection zone Z). Condition).

In this way, when the collecting container 10 capable of crossing the input area Z (permitted) is filled with the downstream input area Z when moving to the input area Z and moving (empty accumulation) In the case where there is no section 22), the apparatus waits and moves when the empty accumulation section 22 is generated upstream of the downstream input region Z.

Further, the picking operation of the picking container 10 (the lowest picking container 10 in the self-inserting zone Z), which has not been completed, is inhibited from moving to the downstream inputting zone Z, whereby the ordered article 11 Generation of this insufficient collecting container 10 is prevented. In addition, at this time, in the downstream input area Z and the input area Z located downstream of this downstream input area Z, accumulation and movement of the some collection container 10 are performed continuously as usual, and an article is collected. The movement of the container 10 is performed efficiently, and the operator's ability is utilized to the maximum.

A specific example will be described with reference to FIG. 17.

Six accumulators 22 are provided in each input area Z. As shown in Fig. 17A, the two collecting containers 10 on the downstream side in the area 2 are not picking targets. If there are two bins (without the container 10) accumulating portion 22 upstream of the adjacent downstream region 3, as shown in FIG. 17 (b), the region is operated by the function of the accumulation conveyor. The two collecting containers 10 on the downstream side in 2 are transferred to the adjacent downstream region 3 and filled up. At this time, the collecting container 10A that is the object of picking operation in the area 2 is transferred to the downstream end of the area, but until the picking operation is completed from the area controller 24 in the picking area P and the front transfer permission signal is outputted, There is no transfer to area 3.

As shown in Fig. 17A, if there is an empty (no collection container 10) accumulator 22 in the region 1, as shown in Fig. 17B, the upstream collecting container 10 As shown in Fig. 17B, when the empty accumulator 22 is generated by the transfer of the collecting container 10 in the region 2, the object is not picked up at the downstream end of the region 1. The collecting container 10 is transferred to the area 2 and filled up. At this time, the collecting container 10A that is the picking target of the region 1 is conveyed to the downstream end of the region, but until the picking operation is completed from the region controller 24 of the picking region P and the front transfer permission signal is outputted, There is no transfer to area 2.

In this way, the collecting container 10 can partially move across the feeding area Z downstream, so that the worker H moves the self-feeding area Z with respect to the collecting container 10A which is a picking target. It is possible to improve the efficiency of the work by increasing the chance of picking work in the range. (Picking work can be performed in the upstream input area Z in advance, but the collecting container 10A as the picking work object is a self-feeding area. It is conveyed to (Z), the working efficiency can be improved.)

In addition, in the input area Z, the collecting container 10A in which the picking operation is performed can be avoided from being transferred to the downstream input area Z until the picking operation in the input area Z is completed. The occurrence of shortages can be prevented.

"Picking operation"; The effect by the structure of the area controller 24 is demonstrated with the picking operation | movement operation of the worker H arrange | positioned in the picking area P. FIG.

As shown in FIG. 7, the lamp 38 of the 2nd lamp part 33 of the input indicator 26 attached to the collection container 10 located in the self-insertion area Z turns on, flashes, or turns off. , There is a picking operation by lighting up, execution of the picking operation by flashing, and no picking operation by turning off, at this time, the bay indicator 20 of the self-picking area P and each supplication indicator 19 are displayed. .

The worker H disposed in the self-picking area P accommodates the article 11 to be fed into the collecting container 10 based on the display of the bay indicator 20 and the display of each supplication indicator 19. When taking out from the box 12 and taking out each time, the completion pushbutton switch 19B of the supplication indicator 19 is pressed, the light of the indication of the supplication indicator 19 is confirmed, and the article 11 is taken out, Looking back, it feeds into the collection container 10 with the feeding indicator 26 which is conveyed to the self-insertion area Z, and the lamp 38 of the 2nd lamp part 33 is flashing (picking). Run the job). And when the input of all the articles 11 is complete | finished, the tape switch 23 of the self-insertion area Z is pressed, and the picking operation | work to the object collecting container 10 of an object is complete | finished. In this way, the lamp 38 of the second lamp unit 33 is only from the self-picking area P when the collecting container 10 with the feeding indicator 26 is located in the self-feeding area Z. It is possible to see and form a self-area lamp that enables picking operations.

In addition, the lamp 38 (only visible from the self-picking area P) of the first lamp part 31 of the feeding indicator 26 attached to the collecting container 10 located in the upstream feeding area Z is The light is turned on or flashing or turned off, the light is turned on, the light is turned on, the light is turned off, the light is turned off, and the light is turned off.

When the lamp 38 of the first lamp unit 31 is blinking, the worker H disposed in the self-picking area P is displayed on the display of the bay indicator 20 in the self-picking area P, respectively. Based on the display of the supplication indicator 19, the collecting container 10 which is located in the adjacent upstream input area Z, and with the input indicator 26 in which the lamp 38 of the 1st lamp part 31 flashed. ), The article 11 taken out from the supplication 16 of the self-picking area | region P is thrown in (preceding picking operation in an upstream area | region). And when the input of all the articles 11 is complete | finished, the tape switch 23 of the upstream input area | region Z is pressed, and the picking operation | work to the target collecting container 10 is complete | finished. In this way, the lamp 38 of the first lamp part 31 is only from the self-picking area P when the collecting container 10 with the feeding indicator 26 is located in the upstream feeding area Z. It is possible to see and form a preceding area lamp which enables the preceding picking operation.

As described above, the worker H can feed the article 11 taken out from the self-picking area P into the collecting container 10 conveyed in the self-feeding area Z and the upstream feeding area Z.
