Japanese Patent Laying-Open No. 2007-8650 (FIG. 3)

In the picking facility disclosed in Patent Document 1, since the picker faces the product rack with the transport unit in between, the shelf of the product rack is basically arranged at a position higher than the upper end of the shipping box. The picker is easy to work with. However, when the product rack shelves are arranged in this way, the lower part of the product rack becomes empty, the number of storage containers stored in the product rack is reduced, and the number of types of items (number of items) required is reduced. If it is going to be secured, it is necessary to spread the product rack along the transport section, which causes a problem that the installation space increases.
Therefore, it is conceivable to lower the position of the shelf, but since the digital display is attached to the tip of the product placement section, if the position of the shelf is lowered, it will be obstructed by the shipping box, making it difficult to see the display section. There is a problem that even if the hand is reached over, the picking completion push button cannot be pressed.

  The present invention is provided with a shelf indicator that can eliminate display inconvenience even when the shelf position is lowered, and as a result, the number of sorting shelves can be increased, and the types of articles handled by the operator can be increased. The purpose of the present invention is to provide a sorting facility that can avoid an increase in installation space.

  In order to achieve the above-described object, the invention described in claim 1 of the present invention includes a sorting shelf provided with a shelf having a plurality of frontage doors in which sorting destinations are assigned or articles to be sorted are stored, A moving means for moving a section or container in which articles are stored, or a section or container to which each sorting destination is assigned, is provided along the sorting shelf, and is moved by an opening of the sorting shelf and the moving means. A sorting facility for performing sorting of the article between the compartment or the container, and a shelf indicator for displaying that the shelf of the sorting shelf for performing the sorting of the article is provided, The shelf indicator is configured such that its height can be adjusted in the vertical direction or the diagonally vertical direction, and the height of the shelf indicator is the upper end of the compartment or container moved by the moving means. Etc., or it is characterized in that is adjusted to a higher position.

  According to the above configuration, the shelf indicator is adjustable in height in the up-down direction or diagonally up-down direction, and the height position of the shelf indicator is adjusted with the upper end of the section or container moved by the moving means. By adjusting to the same or higher position, the problem that the shelf indicator is more difficult to see by the compartment or container is solved.

  The invention described in claim 2 is the invention described in claim 1, characterized in that the direction of the shelf indicator can be adjusted in the front-rear direction of the shelf.

  According to the above configuration, the shelf indicator is adjustable in height in the vertical direction or diagonally up and down direction, and its direction can be adjusted in the front and back direction. Height position and orientation can be adjusted for easy viewing.

  The invention according to claim 3 is the invention according to claim 1 or 2, and is attached to the lowest shelf of the sorting shelf.

  According to the said structure, the shelf indicator located in the lowest shelf of a sorting shelf is hard to see. Therefore, the shelf indicator attached to such a lowermost shelf is particularly easy to see when the height position can be adjusted upward or obliquely upward, and the orientation thereof is further changed.

  Moreover, invention of Claim 4 is invention of any one of Claims 1-3, Comprising: Each said frontage is each equipped with the said shelf indicator, The said sorting shelf WHEREIN: The said sorting A plurality of zones for performing work are formed, and the height position of the shelf display is changed for each of the zones or for each of the frontage.

  According to the above configuration, the height of the shelf is changed because the characteristics, that is, the weight, amount, and shape of the articles to be sorted are different for each zone or for each frontage. Such a change in the height of the shelf changes the relative position between the shelf indicator provided in the frontage and the compartment or container. Readjust to a position higher than the top edge. Therefore, even if the height of the shelf is changed, the shelf display device is not easily seen by the section or the container, and the work efficiency of the worker is improved.

  Further, the invention according to claim 5 is the invention according to claim 4, wherein the zone is arranged on the same side with respect to an operator who performs the sorting work by the sorting shelf and the moving means. A first zone, a sorting shelf and the moving means are configured from a second zone arranged facing the worker, and are moved by the moving means or The article is sorted between the container and the front of the sorting shelf in each of the first zone and the second zone.

According to the above configuration, in the first zone, the sorting shelf and the moving means are arranged on the same side (same surface side) with respect to the worker, so that the worker can sort without changing the direction of the body. Work can be executed and work efficiency is good. However, if the same side, for the operator, because the moving means is located in front of the sorting shelf, the frontage can not be arranged at the position where the worker's hand does not reach by the moving means, that is, the lower position of the sorting shelf, The number of frontage is reduced.
On the other hand, in the second zone, the sorting shelf and the moving means are arranged facing the worker, so that the worker must turn around and change the direction of the body to execute the sorting work. It is not possible to do this, and the working efficiency is poor compared to the first zone. However, since the sorting shelf is not obstructed by the moving means when facing each other, the frontage can be arranged downward in this sorting shelf, and the number of frontage can be increased as compared with the first zone.
Combining the advantages of the first zone and the second zone, the first zone has a frontage with frequent sorting operations, and the second zone has a frontage with less sorting operations compared to the first zone. . As a result, the necessary frontage can be secured in the second zone, and the sorting operation is executed efficiently in the first zone.

  The sorting apparatus according to the present invention is configured such that the shelf indicator is adjusted by the compartment or container by adjusting the height position of the shelf indicator to a position equal to or higher than the upper end of the compartment or container moved by the moving means. It has an excellent effect that the problem of being difficult to see can be solved and the efficiency of sorting work can be improved.

  In addition, because the characteristics of the articles to be sorted, that is, the weight, capacity, and shape are different for each zone or for each frontage, the height of the shelf is changed, but depending on the height of such a shelf By changing the height position of the shelf display, it is possible to make the shelf display easier to see and to improve the efficiency of the sorting operation.

  As described above, the upstream zone memory 72 and the own zone memory 73 store and update the order numbers of the current collecting containers 10 located in the upstream zone Z and the own zone Z from the upstream to the downstream. Further, since the order number of the collection container 10 located in each zone Z is stored by inputting the order number from the RFID reader 42A, the mounting position of the RFID reader 42A is moved to the upstream side or the downstream side. By doing so, the range of the zone Z can be varied. For example, when the upstream zone Z shifts to the downstream side and the own zone Z shifts to the downstream side, the worker H travels around the own zone Z to perform the picking work, and the work efficiency is reduced. Can be improved.

“Own Zone Advance Display Control Unit 78”; The own zone advance display control unit 78 confirms the order number stored in the own zone memory 73, searches the picking memory 71 by each order number, and picks Presence / absence of data (whether there is an article 11 picked from the front opening 14 of the own zone Z and put into the collection container 10 located in the own zone Z; if the picking operation is completed, it is considered that no picking data exists) Ask).
If there is picking data in the order number (if there is picking work), the order number is memorized, and the order number (collection container 10) at the most downstream is selected as the order number (collection object) for picking work. And the number of the own zone Z is added to the order number and output to the picking control unit 79. The local zone lighting data obtained by adding the number of the own zone Z and the lighting signal to the other order numbers excluding the order number of the collection container 10 to be picked is output to the communication controller 63. . Based on the own zone 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 by searching (if there is no picking work), the own zone turn-off data, which is the order number plus the number of the own zone Z and the turn-off signal, is sent to the communication controller 63. Output. When there is no picking data, a no picking data signal is output to the upstream zone preceding display control unit 77. Based on the self-zone turn-off data, the lamp 38 of the second lamp unit 33 is turned off (described later).

“Upstream Zone Advance Display Control Unit 77”; The upstream zone advance display control unit 77 confirms the order number stored in the upstream zone memory 72, searches the picking memory 71 by each order number, and picks. Presence / absence of data (whether there is an article 11 picked from the front opening 14 of the own zone Z and put into the collection container 10 located in the upstream zone Z; “No picking data” if the picking operation is completed) To be considered).
If there is picking data in the order number (if there is picking work), the order number is stored, and then it is confirmed whether or not the picking data no signal is inputted from the own zone preceding display control unit 78. . When the no picking data signal is confirmed, the most downstream order number (collection container 10) is determined as the order number (collection container) to be picked, and the upstream zone Z number (self 1 is subtracted from the number of the zone Z) and output to the picking control unit 79.
Further, upstream zone lighting data obtained by adding the number of the upstream zone Z and the lighting signal to the other order numbers excluding the order number of the collection container 10 to be picked is output to the communication controller 63. . If there is no picking data in the order number by searching (if there is no picking work), the upstream zone extinction data including the order number plus the upstream zone Z number and the extinction signal is sent to the communication controller 63. Output. The lamp 38 of the first lamp unit 31 is turned on based on the upstream zone lighting data, and the lamp 38 of the first lamp unit 31 is turned off based on the upstream zone lighting data (described later).

“Picking control unit 79”; When the picking control unit 79 inputs the order number of the collection container 10 to be picked from its own zone preceding display control unit 78 or the upstream zone preceding display control unit 77, this order number Thus, the picking data in the picking memory 71 is searched. In addition, the local zone blink data or the upstream zone blink data obtained by adding the number of the own zone Z or the upstream zone Z and the blink signal to the input order number is output to the communication controller 63. Based on the own zone blink data, the lamp 38 of the second lamp unit 33 blinks, and on the basis of the upstream zone blink data, the lamp 38 of the first lamp unit 31 blinks (described later).
Subsequently, according to the picking data of the collection container 10 to be picked, the frontage display 15 displays the frontage 14 from which the articles 11 are taken out and the quantity of the articles 11 to be taken out. Then, the operation of the completion push button switch 15B of the frontage indicator 15 confirms the removal of the article 11 from the frontage 14, and the operation of the tape switch 23 (own zone Z) confirms the end of the picking work to the collection container 10. To do. Upon confirmation, the picking data in the picking memory 71 that has been executed is terminated, and the order number for which the picking operation has been completed is output to the forward feed permission control unit 80. Subsequently, in the picking data, the own zone Z is the picking end zone. Check whether it is set to.
In addition, when the own zone Z is set as the picking end zone, it is added to the order number that “order number inversion command” (an example of the display of “finishing of articles”) and a turn-off signal. The zone end unlit data is output to the communication controller 63.

  “Previous advance permission control unit 80”; The forward advance permission control unit 80 searches the picking data in the picking memory 71 based on the most downstream order number of the own zone memory 73 and confirms the presence or absence of the picking work. When no picking operation is performed, the forward feed permission signal is output to the most downstream accumulation unit 22. When picking work is present, the picking control unit 79 waits until an order number for which picking work has been completed is input, and the collection container 10 that has not finished picking work moves from its own zone Z to the downstream zone Z. When the order number is input, it is checked whether or not the order number matches the downstreammost order number of the own zone memory 73. Output permission signal.

  The communication controller 52 is the “own zone lighting data obtained by adding the number of the own zone Z and the lighting signal to the order number” or “the order number, the number of the own zone Z, and the turn-off signal”. "Zone extinction data added to the order number", or "Order number reversal command and zone end extinction data added to the extinction signal" or "Order number, upstream zone" Upstream zone lighting data including Z number and lighting signal ”or“ Upstream zone lighting data adding upstream zone Z number and lighting signal to order number ”or“ Order・ Own zone Z number plus zone number and flashing signal The flashing Data ", or" Order Number, Number of upstream zone Z, and by entering the upstream zone blink data "added that a flashing signal, via the transceiver 53 and antenna 43, transmits.

When this data is received by the wireless device 36 of the input indicator 30, the display controller 35 confirms whether the received data is addressed to itself based on the order number of the received data. Therefore, the “order number” is displayed on the digital display 32, or when the zone end light is off, the “order number” with black and white reversed is displayed on the digital display 32, and the second lamp is displayed as follows. The lamp 33 of the unit 33 and the first lamp unit 31 is turned on / flashing / turned off. It is assumed that red is lit or blinking when the zone Z number is odd, and green when it is even.
-Own zone lighting data: The lamp 38 of the second lamp section 33 is lit.
-Own zone unlit data or zone end unlit data ... The lamp 38 of the second lamp unit 33 is turned off.
-Own zone blink data: The lamp 38 of the second lamp section 33 blinks.

  In this way, the lamp 38 of the second lamp portion 33 of the loading indicator 30 attached to the tray 26 on which the collection container 10 located in the own zone Z is placed is turned on / flashing / turned off and turned on. It is displayed that the collection container 10 is scheduled for picking work, blinks, and is displayed as a collection container 10 that is the target of picking work execution, and is unlit and is a collection container 10 that is not the target of picking work. Is displayed, and the collection container 10 located in its own zone Z, to which the loading indicator 30 is attached, is a collection container to which the articles 11 taken out in its own zone Z are to be loaded. Whether or not.

In addition, the lamp 38 of the first lamp portion 31 of the loading indicator 30 attached to the tray 26 on which the collection container 10 located in the upstream zone Z is placed is turned on / flashing / turned off, and is lit and scheduled for picking work. The collection container 10 is displayed, blinking indicates that it is the collection container 10 that is the target of the picking work, and is turned off, indicating that the collection container 10 is not the target of the picking work. Whether or not the collection container 10 located in the upstream zone Z, to which the input indicator 30 is attached, is a collection container to which the articles 11 taken out in the own zone Z are input by the first lamp unit 31. Is shown.
It should be noted that the state of the lamp 38 of the second lamp portion 33 of the input indicator 30 (lighted / flashing / light-off state) is controlled by the own zone preceding display control portion 78 and the lamp 38 of the first lamp portion 31 The state is controlled by the upstream zone preceding display control unit 77, so that when the collection container 10 is moved from the upstream zone Z to the downstream zone Z, the first lamp unit 31 of the loading indicator 30 and The state of the lamp 38 of the second lamp unit 33 is reviewed at the same time, and the states of both the first lamp unit 31 and the lamp 38 of the second lamp unit 33 are updated simultaneously.

"Action"
The moving operation of the collection container 10 for each zone Z according to the configuration of the straight traveling line 21 and the configuration of the zone controller 24 is as follows.
a. In the zone Z, if there is an empty accumulation unit 22, it is left-justified.
b. The movement across the zone Z is unconditionally output from the corresponding zone controller 24 of the own zone Z facing the own zone Z when the collection container 10 is not a picking work target, and the downstream zone Z When an empty accumulation unit 22 is generated upstream of the first position, it moves.
c. The movement across the zone Z is performed upstream of the downstream zone Z until the forward feed permission signal is output from the zone controller 24 of the zone Z, that is, until the picking operation is completed, when the collection container 10 is the picking work target. Even if an empty accumulation unit 22 is generated, it does not move and stops, and the most downstream collection container 10 that has not finished picking work is prevented from moving to the downstream zone Z, allowing forward feed. It moves to the downstream zone Z for the first time by the output of the signal (provided that an empty accumulation unit 22 is generated upstream of the downstream zone Z).
In this way, when the collection container 10 capable of crossing the zone Z (allowed) moves across the zone Z and the downstream zone Z is clogged (there is no empty accumulation part 22). In the case), the system waits and moves to the downstream zone Z when the empty accumulation unit 22 is generated.

The operation of the zone controller 24 will be described together with the sorting work operation of the worker H arranged in the zone Z.
As shown in FIG. 3, the lamp 38 of the second lamp portion 33 of the loading indicator 30 attached to the tray 26 on which the collection container 10 located in the own zone Z is placed is turned on, blinked, or turned off. When picking up, the picking work is performed, when blinking the picking work is executed, and when no light is picked up, the picking work is not displayed. At this time, the frontage indicators 15 are displayed.
The worker H arranged in his / her zone Z takes out the article 11 to be put into the collection container 10 from the storage box 11 </ b> A based on the display of each frontage indicator 15, and completes the frontage indicator 15 each time it is taken out. The push button switch 15B is pressed to confirm that the display on the frontage indicator 15 is turned off, the article 11 is taken out, and the article 11 has been transported to the own zone Z, and the lamp 38 of the second lamp section 33 is blinking. The tray 30 to which the container 30 is attached, that is, the collection container 10 is loaded (picking operation is executed). When all the articles 11 have been charged, the tape switch 23 in the own zone Z is pressed, and the picking operation for the target collection container 10 is completed. In this way, the lamp 38 of the second lamp section 33 can be seen only from the own zone Z when the collection container 10 to which the loading indicator 30 is attached is located in the own zone Z, and can be picked. The self-zone lamp is formed.

In addition, the lamp 38 of the first lamp portion 31 of the loading indicator 30 attached to the collection container 10 located in the upstream zone Z (which can be seen only from the own zone Z) is turned on, blinking, or turned off. Picking work is displayed, blinking indicates that the picking work is executed, and no light is displayed when the lamp is turned off.
When the lamp 38 of the first lamp unit 31 is blinking, the worker H arranged in the own zone Z is located in the adjacent upstream zone Z based on the display of each frontage indicator 15 in the own zone Z. The article 11 taken out from the slot 14 of the own zone Z is loaded into the tray 26 to which the loading indicator 30 in which the lamp 38 of the first lamp unit 31 is flashing, that is, the collection container 10 (upstream). Perform pre-picking work in the zone). When all the articles 11 have been charged, the tape switch 23 is pressed, and the picking operation for the target collection container 10 is completed. As described above, the lamp 38 of the first lamp unit 31 can be seen only from the own zone Z when the collection container 10 to which the input indicator 30 is attached is located in the upstream zone Z. A leading zone ramp is made possible.

As described above, the worker H can put the article 11 taken out from the own zone Z into the collection container 10 being conveyed in the own zone Z and the upstream zone Z. As shown in FIG. For each worker H, a range in which the loading operation can be performed over two continuous zones Z is formed. In addition, with the exception of the most downstream zone Z, a zone Z in which two people carry out the loading work into the collection container 10 continues from the most upstream zone Z, and only one worker is in the most downstream zone Z. It becomes the zone Z in which the loading operation into the collection container 10 is performed. That is, by enabling the worker H to perform the picking work in the own zone Z and the upstream zone Z, the zones Z in which each worker H can execute the picking work are adjacent to each other except the most downstream zone Z. The zones Z are arranged so as to be continuously shifted and overlapped, and in each zone Z, picking work is executed by two workers.
Further, when the picking work to the collection container 10 is finished due to the completion of the picking work, black and white is reversed and the order number is displayed on the digital display 32.
Further, the digital device (display screen) 32 of the input indicator 30 is attached to the center of the lamp (own zone lamp) 38 of the second lamp unit 33 and the lamp (preceding zone lamp) 38 of the first lamp unit 31. It is easier to see than an operator who puts the article 11 into the collection container 10 to which the loading indicator 30 is attached.

  As described above, according to the present embodiment, the height position of the frontage indicator 15 (display main body 15C) is set in the vertical direction or the diagonally vertical direction from the position of the attached shelf 13 by the lifting jig 16. By making the change (adjustment) possible, the frontage indicator 15 (display main body 15C) is located at a position where the surface quantity indicator 15A is easy to see and the completion pushbutton switch 15B is easy to operate according to the shelf position of the flow rack 12. Thus, the work efficiency of the worker H can be improved. Therefore, in particular, in the sorting equipment in which the flow rack 12 and the straight traveling line 21 are arranged on the same side with respect to the worker H, the display is easy to see even if the position of the lowest shelf 13 is lowered, and the operation is easy. It is possible to provide an easy-to-use frontage display 15 and, as a result, the number of shelves 13 can be increased, the types of items 11 (number of items) handled by the operator H can be increased, and the installation space for the flow rack 12 can be expanded. Can be avoided.

  Further, according to the present embodiment, the height position of the frontage display 15 (display body 15C) can be changed from the position of the attached shelf 13 to the vertical direction or the diagonally vertical direction from the lifting jig 16. In addition, since the orientation of the frontage display 15 (display main body 15C) can be changed in the front-rear direction, the quantity indicator 15A on the surface is easy to see according to the shelf position of the flow rack 12, and the completion push button switch 15B Thus, the height and orientation of the display body 15C can be changed to a position where it is easy to operate, and the work efficiency of the worker H can be improved.

  Further, according to the present embodiment, the frontage indicator 15 located on the lowest shelf 13 of the flow rack 12 is difficult for the operator H to see the quantity indicator 15A on the surface and difficult to operate the completion pushbutton switch 15B. The frontage indicator 15 attached to the lowermost shelf 13 from the lifting jig 16 changes the height position of the indicator main body 15C upward or obliquely upward from the position of the attached shelf 13. When (adjustment) is performed, if the orientation of the display unit main body 15C is further changed (adjusted), the quantity display unit 15A on the surface becomes easy to see and the completion push button switch 15B becomes easy to operate. Therefore, when the straight transport line 21 and the flow rack 12 are on the same side with respect to the worker H, the front end of the lowermost shelf 13 is positioned below the upper end of the collection container 10 transported by the straight transport line 21. As a result, the position of the lowermost shelf 13 can be lowered, so that the height position of the entire shelf 13 can be lowered, and the working efficiency of the worker H can be improved.

  In addition, according to the present embodiment, each collection container 10 conveyed by the straight conveyance line 21 is a collection product to be thrown into which the article 11 taken out from the frontage 14 is thrown by the display of the loading indicator 30 that moves together. Even if the worker H is identified as a container and is continuously transported by the straight transport line 21 by putting the article 11 taken out from the frontage 14 into the displayed collection container 10, Picking work can be performed.

  Further, according to the present embodiment, for each zone Z, the collection container 10 is moved and packed downstream, and the collection container 10 that has finished picking work in the zone Z is moved to the downstream zone Z. As a result, the collection container 10 is easily moved between the zones Z without being affected by other zones Z, and the collection container 10 is efficiently moved to maximize the ability of the worker H. You can save it.

In the above embodiment, by changing the inclination of the adjustment unit 20 connected to the attachment unit 19, the front-rear direction of the display body 15C via the adjustment unit 20 and the first support unit 17 (elevation adjustment plate 17B). However, by attaching the second support portion 18 to the shelf 13 at an angle, the attachment portion 19 is eliminated, and the vertical adjustment plate 17B is placed directly on the second support portion 18 in a vertical posture. It is possible to change the display body 15C in the diagonally up and down direction even if it is fixed with, that is, without the function of changing the orientation of the display body 15C in the front-rear direction.
Further, the lifting jig 16 adjusts the height position of the display body 15C by changing the position of the first adjustment hole 17A of the lifting adjustment plate 17B facing the second adjustment hole 20B of the adjustment unit 20. However, the present invention is not limited to such a configuration. For example, a configuration in which the elevation adjustment plate 17B is slid up and down with respect to the adjustment unit 20 may be employed.
Further, although the lifting jig 16 is provided for each display body 15C, one lifting jig 16 may be provided for each of the plurality of display bodies 15C. At this time, the positions of the plurality of display bodies 15C can be adjusted simultaneously in the vertical direction and further in the front-back direction.

  Moreover, in the said embodiment, although the height position of the frontage indicator 15 (display body 15C) provided in the lowest shelf 13 is raised to a certain height position by the lifting jig 16, the zone You may make it change the height position of the frontage display 15 (display body 15C) for every Z or for every frontage 14. FIG. Accordingly, the height of the shelf 13 is changed because the characteristics, that is, the weight, the capacity, and the shape of the articles 11 to be sorted are different for each zone Z or for each frontage 14. By changing the height position of the display unit main body 15C corresponding to the height of 13, the surface quantity display unit 15A can be easily seen and the completion push button switch 15B can be operated easily, improving the work efficiency of the worker H. it can.

  Moreover, in the said embodiment, the frontage indicator 15 lifted / lowered by the raising / lowering jig | tool 16 is each user (sorting destination) in which the articles | goods 11 of the storage container 11A accommodated in the frontage 14 are conveyed by the rectilinear conveyance line 21. Is used in the facility for sorting into the collection container 10 assigned, but conversely, from the storage container (an example of the container in which the articles to be sorted) are transported by the rectilinear transport line 21, is stored in the frontage 14, It can also be used in equipment for sorting articles 11 into collection containers (an example of a frontage to which sorting destinations are assigned) 10 to which each user (sorting destination) is assigned. At this time, the frontage display 15 displays the quantity of articles 11 to be collected in the collection container 10.

Further, in the present embodiment, the flow rack 12 and the straight conveyance line 21 are disposed on the same side with respect to the worker H to form a zone (first zone) Z. A zone (second zone) is newly provided on the side opposite to the straight conveyance line 21 with the worker H in between (on the side facing the straight conveyance line 21 with the worker H in between), and the straight conveyance line passing through these zones The sorting operation of the articles 11 may be performed between the container (collection container 10 or the storage container 11A) conveyed by 21 and the opening 14 of the first zone and the second zone.
According to the above configuration, the container is transported across the two first zones and the second zone, and in each zone, the sorting work is executed, so that an article (high-order) ordered by the user is high. (Frequency goods) sorting work is concentrated on the first zone where work efficiency is high, and goods that are ordered by a user at a low rate (low frequency goods) are sorted in the second zone. As a result, the sorting equipment as a whole can be expected to improve the efficiency of sorting work, and the required number of frontage 14 can be secured.
Further, in the first zone, since the flow rack 12 has the straight traveling line 21, even if the shelf 13 is provided on the back side (the side opposite to the worker H) of the straight traveling line 21, as shown in FIG. There is a limit and the number of steps of the shelf 13 is limited. However, in the second zone, there is no such limitation, and the shelf 13 can be installed from a position close to the floor, and the number of steps can be increased. Therefore, in the second zone, the number of front doors 14 can be increased, and it is extremely effective to provide the second zone in a sorting facility having a large number of users or a large number of types of items 11 (number of items).

In this embodiment, the container 25 is used as the collection container 10. However, the collection container 10 may be any type as long as it can temporarily store the articles 11 and can be placed on the tray 26. For example, it may be a cardboard, a pallet, or the like, and the articles 11 can be collected on the tray 26. Further, the input indicator 30 can be attached to each accumulation unit 22 of the straight conveyance line 21 and used as a section (area) for collecting the accumulation unit 22 instead of the collection container 10.
Although the collection container 10 is placed on the tray 26 and transported, the collection container 10 may be transported directly. At this time, the input indicator 30 is directly collected using a jig so that the surface of the input indicator 30 is positioned below the upper end of the collection container 10 and is at the same height as the tape switch 23. The upper end of the container 10 is attached to the worker H side.

In the above embodiment, the storage container 11A is stored in the flow rack 12, but the article 11 may be stored as it is. When the articles 11 are stored as they are, it is possible to narrow the vertical interval between the shelves 13, thereby increasing the number of the shelves 13 from which the operator H can take out the articles 11 and the number of columns of the frontage 14. This makes it possible to increase the number of items 11 that can be stored.
Further, in the embodiment, the storage box 11A placed on each shelf 13 of the flow rack 12 is configured by a box (box) whose upper surface is opened and the article 11 can be taken out from above. A box (including a box in which the front surface is opened by laying down the box and a rising portion of the front surface is cut off) in which the front surface (surface facing the worker H) is opened and the article 11 can be taken out from the front. ), Or pallet (a flat plate on which the articles 11 can be stacked; including a box / tray with a thin bottom), or a basket (including a box with a slot on the front side so that the article 11 can be seen from the front) Etc. may be used.
Moreover, in this Embodiment, although the flow rack 12 is used as a sorting shelf, the general shelf to which the articles | goods 11 or a storage box does not move can also be used.
Further, in the present embodiment, each shelf 13 of the flow rack 12 is fixed, but it may be configured so that it can be arbitrarily moved and adjusted back and forth (in the direction of the rectilinear transport line 21).

Further, in this embodiment, the rectilinear transport line 21 is configured by an accumulation conveyor, but the rectilinear transport line 21 may be configured by a free roller conveyor (hereinafter referred to as a free conveyor).
In this embodiment, the tape switch 23 is used as a means for inputting the completion of the picking work. However, any switch that simply inputs the completion of the picking work may be used, and a simple push button switch may be used.
Further, in the present embodiment, each zone Z is configured to arrange one worker H, but may be configured to arrange a plurality (for example, two) workers H in each zone Z. . As a result, even in a situation where the collection container 10 to be picked into the zone Z is carried in without any gap, the work speed in the zone Z is improved, so that each collection line B is urgently stopped. It is possible to reduce the possibility of occurrence of picking up and improve the efficiency of picking work.
In this embodiment, the sorting destination is classified by user. However, the sorting destination is not limited to the user, and may be classified by store, by category or category such as products, by region, by transport truck, and the like.
