Description

  The present invention relates to a sorting door device that sorts articles.

An example of a conventional sorting facility is disclosed in Patent Document 1.
A frontage display is provided that includes a sorting shelf having a plurality of frontage boxes for storing collection containers for sorting products (an example of goods), and displays the quantity of products to be put into the frontage collection containers corresponding to each frontage. A vessel is provided.
The sorting shelf uses a cart for each store that maximizes the total number of frontage, according to the sorting request data formed from the product name and quantity of the product ordered (or requested) by the store. The collected product group is conveyed.

  When the operator retrieves the same type of product that has been noticed from the cart and enters the barcode and quantity of the retrieved product, the quantity of the entered product is based on the barcode, quantity, and product sorting data. The frontage (corresponding to the sorting destination) and the quantity of the product to be sorted into each frontage are obtained, and the obtained quantity of the sorted product is output to the frontage frontage indicator. It has become.

  With this configuration, the operator can sort only the amount of products that are taken out according to the instructions on the frontage display device, so there is no need to search for the same type of products from the cart and sort them all, improving sorting efficiency can do.

However, the following problems have been pointed out for such conventional sorting equipment.
1. When a product is put in, it is often mistakenly put into the next door or the upper and lower doors (incorrectly put), shipped as it is, and not found until delivery. In this case, a complaint (complaint) is generated from the user, and it takes a lot of time and effort to process the complaint. In addition, there is a system that issues an alarm by detecting that the operator's hand has entered other than the frontage where the product is put in by using an optical sensor, but there is a range where it cannot be detected, and it is not possible to prevent erroneous insertion reliably.
2. Some products (medicine, etc.) are life-threatening if shipped accidentally.

  In order to prevent such an erroneous insertion, Patent Document 2 discloses a sorting facility that has an open / close door that physically shields the opening space of the frontage and that directly prevents the introduction of goods. ing.

FIG. 1 is a front view of a sorting shelf of the sorting door device according to the embodiment of the present invention, and FIG. 2 is a side view of the sorting shelf of the sorting door device.

  In FIG. 1, reference numeral 11 denotes a sorting shelf to which each sorting destination is assigned and a plurality (12 in the figure) of front doors 14 each storing a collection container 13 for sorting merchandise (an example of an article) 12 is distributed left and right. As shown in FIGS. 1 and 3, the sorting shelf 11 is provided with a controller 15 (an example of management means) made up of a computer at the center upper portion. Below, a keyboard hanging shelf 16a with a keyboard 16 mounted thereon, a liquid crystal display panel 19 comprising a liquid crystal display panel 17 and a touch panel 18 formed on the display screen of the liquid crystal display panel 17, and a portable barcode wireless Type scanner 21 and a fixed bar code wired scanner 22 are provided. Shelf 23 is provided.

[Frontage] As shown in FIG. 1, the frontage 14 has two upper and lower stages on the left and right sides of the keyboard 16 at the center, the liquid crystal display device 19, the wireless scanner 21, the wired scanner 22, the controller 15, and the like. The shelves 24 are arranged in three rows, that is, six fronts 14 are arranged on the left and right.
Further, above the two-tier shelf 24 where the frontage 14 is arranged, that is, above the sorting shelf 11, a shelf 24 is provided in which the cushioning material or the like of the products 12 collected in the collection container 13 is stored in advance. .

  [Shelves] As shown in FIGS. 2 and 4, the shelves 24 arranged at the upper and lower sides are front shelf boards (an example of a first support portion) disposed in front of the products 12 into the collection container 13. ) 25, 25 ′, and a round bar processing shelf board (an example of a second support part) 27 disposed behind the space part 26. Further, the round bar processing shelf board 27 is provided with a partition plate 28 for partitioning each frontage 14 in the left-right direction perpendicular to the front-rear direction. Further, the front shelf boards 25 of the upper and middle shelves 24 of the sorting shelf 11 are formed in an L-shaped cross section with the rear part bent downward, and the front shelf boards 25 'of the lower shelf 24 are formed in a prismatic shape. Has been. The front shelf plate 25 ′ of the lower shelf 24 may have a width that allows the front portion of the collection container 13 to be placed, and may be a square bar or a round bar.

  Further, as shown in FIG. 2, each shelf 24 is inclined so that the rear end is higher than the front end of the shelf 24, and the inclination angle is variable. The inclination angle is 10 °, and the inclination angles of the middle and upper stages are 15 °. If the inclination angle of the shelf 24 is decreased as it is lower, the inside of the collection container 13 becomes easier to see. If the inclination angle is increased as the upper stage, the inside of the collection container 13 becomes easier to see, depending on the height position (number of stages). Thus, the tilt angle is adjusted.

  As shown in FIG. 2, at least the depth width of the front shelf 25 ′ of the lower shelf 24 is made thinner than the front shelf 25, and the collection container 13 is moved to the front from the front shelf 25 of the middle shelf 24. The opening of the collection container 13 accommodated in each frontage 14 (shelf 24) in the lower stage can be configured so that it can be seen well.

  The round bar processed shelf 27 has a predetermined angle (10 ° to 20 °) with the front end being the same height as the horizontal portion of the front shelf 25, 25 ′ and the rear end being higher than the horizontal portion of the front shelf 25, 25 ′. And a pair of front and rear L-shaped square members 29 arranged in the left-right direction at this angle, and arranged in the front-rear direction with respect to the pair of square members 29, with a predetermined interval in the left-right direction. A plurality of stainless steel round bars (an example of a wire rod) 30 arranged side by side.

The upper and middle front shelves 25 need only have a width that allows the front part of the collection container 13 to be placed, and can be a round bar. A function of guarding the upper side of the display 41 with the shutter is required so that the display 41 with the shutter 41 is prevented from being damaged due to the installation and unloading of the collection container 13. The shape and width (front and rear width) of the display 42 with shutter 41 covering the upper and rear sides of the main body 42 are set.
Further, the front shelf boards 25, 25 'are slippery and sufficiently strong, for example, stainless steel plates (for example, made of stainless steel) (the upper surface is always rubbed by the collection container 13 when the collection container 13 is installed / unloaded. An example of a material that can support the weight of the entire collection container 13 and that does not wear even if the collection container 13 is slid is used.

The space 26 is provided to drop a corner of the bottom end of the front end of the collection container 13, and the length (width) in the front-rear direction of the collection container 13 and the height direction of the front surface of the collection container 13. Is made longer than the width (dimension) of the space portion 26 in the front-rear direction. Thereby, even if the front end portion of the collection container 13 is dropped into the space portion 26, the collection container 13 is prevented from falling downward through the space portion 26, and the collection container 13 is fitted into the space portion 26. The risk of being lifted is avoided. If the round bar processing shelf board 27 can be changed in the front-rear direction, the width (dimension) in the front-rear direction of the space 26 can be changed.
With the configuration of the shelf 24 (frontage 14) as described above, as shown in FIG. 6, the collection container 13 can be easily installed and taken out, and the inclination angle can be easily changed. That is, when the front end portion of the collection container 13 is dropped into the space portion 26 during the handling operation (input operation and removal operation) of the product 12, the front shelf board 25 (25 ′) and the round bar processing shelf board 27 The collection container 13 is supported so that the handling work posture (inclination angle) can be easily changed.

The operation at the time of installing / unloading the collection container 13 will be described with reference to FIG.
When putting the collection container 13 into the shelf 24 (frontage 14), the operator puts the bottom of the front end of the collection container 13 on the front shelf 25 (25 ') and pushes it backward, and then the rear end of the collection container 13 The bottom is supported by the round bar 30 of the round bar processing shelf board 27. At this time, since the round bar 30 is inclined, the corner portion of the rear end bottom of the collection container 13 makes point contact with the round bar 30. Accordingly, when the front end of the collection container 13 is pushed into the space 26, the resistance between the corner of the bottom end of the collection container 13 and the round bar 30 (round bar processing shelf 27) is The collection container 13 is rubbed while being slid and moved backward with a small and light force.

  Further, when taking out the collection container 13 from the shelf 24 (opening 14), the operator lifts the front end of the collection container 13 from the space 26 and places it on the front shelf 25 (25 '). At this time, the corner of the bottom end of the collection container 13 is in point contact with the round bar 30, and when the collection container 13 is pulled, the corner of the bottom end of the collection container 13 and the round bar 30 are pulled as described above. The resistance to the (round bar processing shelf 27) is small, and the collection container 13 is rubbed and moved forward with a light force while sliding.

  In this way, when the collection container 13 is installed and taken out, the corner of the bottom end of the collection container 13 is brought into point contact with the round bar 30 of the round bar processing shelf 27, thereby reducing the ground contact area. Resistance when pushing and pulling the product container 13 is reduced, and the burden on the operator can be reduced.

The change of the inclination angle of the collection container 13 will be described with reference to FIGS. 6 (b) and 6 (c).
As shown in FIGS. 6 (b) and 6 (c), when the corner portion of the front end bottom of the collection container 13 is dropped into the space 26, the collection container 13 is inclined forward, and the round bar processing shelf plate 27 Since the front end of the round bar 30 has the same height as the front shelf 25 (25 ′), the collection container 13 is in line contact with the front shelf 25 (25 ′), and the round bar of the round bar processing shelf 27 It is point-contacted with 30, and the inclination angle of the collection container 13 can be easily changed by the operator's intention. As shown in FIG. 6B, when the inclination angle is increased, the opening (upper surface) of the collection container 13 can be seen well, and the product 12 can be easily inserted (or the product 12 can be easily taken out). Further, as shown in FIG. 6 (c), when the collection container 13 is filled with the product 12 and the inclination angle is returned and reduced, the product 12 thrown from the collection container 13 is prevented from spilling (so as not to fall). To).

  Further, as shown in FIG. 2, each of the middle and lower shelves 24 (frontage 14) of the sorting shelf 11 is used as a stage in which the collection container 13 into which the product 12 is actually put is stored {FIG. 1 In FIG. 4, the front opening 14 in which the collection container 13 is stored is designated as 14 (1) to 14 (12) in order from the left on the left in the middle to the middle and lower, and from the left on the right to the middle and lower. And, in the vicinity of the lower part of the front shelf plate 25 of the upper stage and the middle stage, there is provided a mounting material 32 made of a round bar for mounting the display with shutter 41 in the left-right direction, corresponding to each frontage 14 of the middle stage and the lower stage, respectively. The indicator 41 with a shutter is attached to the attachment member 32, and thus the indicator 41 with a shutter is provided above each of the front doors 14 in which the collection containers 13 into which the goods 12 are actually put are stored. Is arranged. The upper and middle front shelves 25 are each provided with a unique code (bar code) assigned to each frontage 14 corresponding to each lower frontage 14 on the side of the display 41 with shutter. An ID label 34 (FIG. 4) is attached.

  Further, the collection container 13 is configured by a foldable container, and is stored in a state of being folded in the upper stage of the sorting shelf 11 so that the empty collection containers 13 can be replenished to the front doors 14 in the middle and lower stages. Has been. Each collection container 13 is provided with an ID label 35 (FIG. 4) on which an assigned specific code (bar code) is written.

  Further, as shown in FIG. 1, a step board 36 for an operator who puts the product 12 into the collection container 13 at the frontage 14 is provided below the lower side of the sorting shelf 11 as shown in FIG.

[Display 41 with shutter]
The display 41 with a shutter has a function of displaying whether or not the product 12 is to be put into the collection container 13 stored in the frontage 14 and the quantity of the product 12 to be thrown, and the product 12 is put in by mistake. It has a function to physically prevent it.

  As disclosed in Japanese Patent Application Laid-Open No. 2010-6609, a conventional display with a shutter is moved forward (outward) from a position where the shutter covers the frontage (a 90 ° position perpendicular to the lower side from the horizontal position). Because it is configured to rotate and open up to a 90 ° position perpendicular to the upper side, that is, it is configured to open to the worker side that puts the product into the frontage, when the worker is approaching, There is a problem that there is a risk of contact, and the product cannot be put in until the product has been opened, resulting in poor work efficiency.

  In order to solve this problem, as shown in FIGS. 2, 4, and 5, the shutter-equipped indicator 41 is configured to open the open / close door (shutter) 43 to the rear side (collection container 13). The fear of the door 43 coming into contact with the operator is eliminated, and the work efficiency is improved.

  As shown in FIGS. 4 and 5, the shutter-equipped indicator 41 includes a main body 42, the opening / closing door (shutter) 43 that physically prevents the product 12 from being put into the collection container 13, and the opening / closing door 43. A pair of left and right L-shaped arms 44 to be attached and a holder 45 for attaching the main body 42 to the attachment member 32 are provided.

  As shown in FIG. 5 (b), each L-shaped arm 44 is rotated on the left and right side surfaces of the main body 42 from a position of 90 ° perpendicular to the lower side to a position of 0 ° horizontally rearward. That is, the open / close door 43 attached to the arm 44 is provided so as to open to the back side of the frontage 14.

  The holder 45 is provided on the back surface of the main body 42, and can be opened from a 90 ° position perpendicular to the lower side to a horizontal 0 ° position rearward, and is semicircular in accordance with the cross section of the mounting member 32. And a fixing portion 47 that fixes the tip of the supporting device 46 in a state of being engaged with the mounting material 32 to the main body 42. When the supporting device 46 is engaged with the mounting material 32, the fixing device 47 fixes the fixing device 47. The shutter-equipped display 41 is attached to the attachment member 32.

  The opening / closing door 43 is supported by an arm 44 and attached to a first door portion 49 made of a rectangular yellow plate (board) which is driven to open and close, and a lower end of the first door portion 49 (hanging). And the second door portion 50 made of a rectangular yellow cloth material made of soft resin or cloth. Moreover, the horizontal dimension of the left-right direction of the opening / closing door 43 (the 1st door part 49 and the 2nd door part 50) is made narrower than the width | variety of the left-right direction of the collection container 13 installed in the frontage 14. FIG. Further, the vertical dimension of the first door portion 49 is such that it does not come into contact with the collection container 13 that is tilted and stored in the frontage 14 and can be physically prevented from being put into the frontage 14 of the product 12. In the center, a notch 49a for avoiding contact with the main body 42 is provided. The vertical dimension of the second door portion 50 is a dimension that covers the gap where the first door portion 49 cannot cover the collection container 13. In addition, since the 2nd door part 50 is a soft cloth material, there is no possibility that it will be damaged even if it contacts with the collection container 13, and there is no possibility that it will be damaged even if an operator touches it.

  With such a configuration of the opening / closing door 43, first, the second door portion 50 is suspended from the first door portion 49 in the closed position (at a 90 ° position perpendicular to the lower side). A gap with the collection container 13 is filled, and visually, the operator is prevented from putting the product 12 into the collection container 13. Then, as shown in FIG. 5 (b), when the product 12 is opened so as to allow the product 12 to be put into the collection container 13 accommodated in the frontage 14, that is, a closed position (a 90 ° position perpendicular to the lower side). When the first door portion 49 made of a plate material is rotated in synchronization with the posture of the arm 44 in accordance with the rotation operation of the arm 44, the second door 49 is rotated in the second position. Since the door portion 50 is formed of a soft cloth material, the door portion 50 slides rearward while maintaining a vertical posture hanging vertically from the lower end of the first door portion 49. Thereby, immediately after the opening / closing door 43 starts the opening operation, even if the opening of the collection container 13 is opened by the second door portion 50, it is obstructed by the first door portion 49 in an oblique posture and the product 12. Is difficult to put in, and the second door portion 50 is large and visible to the operator, so that the putting operation of the product 12 is braked. Thereafter, when the first door portion 49 is rotated about 90 °, the second door portion 50 opens half of the opening of the collection container 13, and the second door portion 50 becomes difficult to see. There is no obstacle, and the second door 50 is a soft material, so that the product 12 can be put in.

  The main body 42 of the shutter-equipped display 41 is provided with a three-digit digital display (instruction means) 51 and a completion button switch (operation means) 52 with a lamp (instruction means) 52a on the front, and an arm 44 inside. The drive part (not shown) is provided.

  The controller 15 receives the quantity data to be displayed on the digital display 51, the lighting / extinguishing signal of the lamp 52a, and the opening / closing signal of the arm 44, that is, the door 43, from the controller 15. An operation signal for the completion button switch 52 is output from the display 41 to the controller 15. The shutter-equipped display 41 to which these signals and data are input automatically opens and closes the open / close door 43, blinks and extinguishes the lamp 52a, and displays and deletes the quantity on the digital display 51.

  As described above, according to the shutter-equipped display 41, when the open / close door 43 is in the closed position (a 90 ° position perpendicular to the lower side), the product 12 is physically prevented from being erroneously inserted and remains erroneously input. It is avoided that the product 12 (medicine, etc.) is related to human life by shipping. Also, if the door 43 is opened to the front side of the front door 14, there is a risk of contact with the operator when the door 43 is opened, but the door 43 is guided (operated) to retreat in a predetermined direction, That is, opening to the back side of the frontage 14 (acting (acting) in a direction away from the frontage 14) eliminates the possibility of contacting the operator when the open / close door 43 is opened. Further, the width in the left-right direction of the opening / closing door 43 is narrower than the width in the left-right direction of the collection container 13, so that the possibility of contact with the collection container 13 when the opening / closing door 43 is opened / closed is avoided. It is possible to have the collection container 13 without being obstructed by the opening / closing door 43 when installing / unloading 13, thereby improving workability.

  In FIG. 1, reference numeral 61 denotes a cart (cart) that transports a storage container 62 that stores products 12 to be sorted in the sorting shelf 11 for each batch, and 63 is arranged on the right side of the sorting shelf 11. This shipping conveyor device is used to transport the collection container 13 that has been sorted. The storage container 62 of the cart 61 is formed from the product name and quantity of the product 12 ordered (or requested) by the store in the store area where the total number 12 of the frontage 14 into which the product 12 is input is maximized. In accordance with the sort request data {formed for each batch; see FIG. 9 (a)}, the products are collected in advance for each product 12, and the collected product group is conveyed. Further, an ID label 64 on which an ID code (bar code) for identifying the storage container 62 is attached is attached to the storage container 62, and the collection of the collection into the storage container 62 is performed on this ID code (bar code). The batch number of the request data is linked {see FIG. 9B}. The storage container 62 is lowered from the cart 61 to the slide shelf 23 opened forward as shown in FIG. 3B, and sorting of the stored products 12 is started.

[Control Configuration] FIG. 8 shows a control configuration diagram of the sorting door device having the above configuration.
Connected to the controller 15 are a keyboard 16, a liquid crystal display panel 17 and a touch panel 18 of the liquid crystal display device 19, a wireless scanner 21 and a wired scanner 22, and twelve display devices 41 with shutters to manage logistics. The sorting request data for each batch shown in FIG. 9A and the storage container data shown in FIG. 9B are input in advance from the host computer. As described above, the sorting request data is formed from the batch number, the store name (up to 12 stores), and the product name and quantity of the product 12 sorted for each store, and the storage container data specifies the storage container 62. The ID code and the batch number are formed. The controller 15 stores data of each product 12, that is, a product code corresponding to the JAN code attached to the product 12 and a product name in advance.

  Further, the controller 15 obtains the number of stores to be sorted for each batch based on the batch sorting request data inputted in advance, and obtains the quantity of the product 12 for each store as shown in FIG. (Sorting amount per frontage), the quantity for each product 12 is obtained and stored as product data (sorting amount by product), and the number of items of all products 12 is obtained and stored, and the quantity of all products 12 is stored. Is stored as the total amount of sorting.

  Then, in order from a store with a large amount of sorting for each frontage, that is, a collection container 13 with a large amount of products 12 to be input, a preferentially determined frontage 14 in consideration of workability (close to the wired scanner 22 and the liquid crystal display device 19). Even if the worker does not move, the frontage 14) in which the product 12 can be put in within the reach of the hand is assigned. For example, in FIG. 1, it is assigned in the order of 14 (7), 14 (3), 14 (10), 14 (6)... Although details will be described later, it is intended to improve workability by placing the storage container 62 storing the products 12 to be sorted on the slide shelf 23 in the center and executing the sorting work.

[Display Screen] FIG. 7 shows a sorting setting screen displayed on the liquid crystal display panel 17 of the liquid crystal display device 19. In this sorting setting screen, sorting work is executed.
As shown in FIG. 7, the wireless scanner 21 reads an ID code for identifying the storage container 62 from the ID label 64 of the storage container 62, and the storage container 62 is in accordance with the number of the batch linked to the ID code. A batch display unit 66 for displaying data and a sorting display unit 67 for displaying sorting instructions are displayed. Further, “POS inspection completion” for inputting inspection completion, which is operated on the touch panel 18, and collection from the sorting shelf 11. A “collection container unloading completion” button to be input when all the containers 13 are unloaded is displayed.

  The batch display unit 66 displays the batch number, the number of stores to be sorted, the number of items of the product 12, and the total sorting amount (total sorting number) searched by the batch number, and the sorting display unit 67. Includes a JAN code displayed by reading a barcode (an example of information for identifying an article) attached to the product 12 with the wired scanner 22, and the code of the product 12 and the product retrieved by the JAN code. 12 names (product names), the number of sorting, and the sorting amount in each frontage 14 are displayed.

  [Sorting Control and Sorting Operation] The sorting control by the controller 15 will be described based on the flowchart of FIG. 10 and the explanatory diagrams shown in FIGS. It is assumed that the doors 43 are initially closed at all the front doors 14 and the product 12 cannot be put into the front doors 14 {see FIG. 11A}.

  First, when the storage container 62 is conveyed by the cart 61, the operator opens the slide shelf 23 and transfers the storage container 62 from the cart 61 to the slide shelf 23. As a result, the storage container 62 is positioned directly below the liquid crystal display device 19, the wireless scanner 21, and the wired scanner 22, and the operator can easily work.

Step-1
The operator reads the ID code of the ID label 64 of the storage container 62 with the wireless scanner 21. Then, the controller 15 searches the storage container data to obtain the number of the batch linked to this ID code, searches the sorting data by the number of this batch, and stores the number of stores, the number of items of all products 12, The total sorting amount (total number of sorting) is obtained and displayed on the batch display unit 66 of the liquid crystal display panel 17, and the frontage allocation data is searched to obtain the frontage 14 assigned to each store.

Step-2
The controller 15 outputs an open signal (opening command) for the doors 43 to all the display devices 41 with shutters, and all the display devices 41 with the shutters open the doors 43 (opening and closing doors to allow work). 43 is released). Thereby, the opening and closing door 43 is released in advance before work, a space necessary for the work is formed, and the situation that it is difficult to set the collection container 13 in the front door 14 because the door 43 is closed is avoided. Subsequently, the blinking signal of the lamp 52a is output to the shutter-equipped display 41 in the front door 14 to which each store is assigned, and the display 41 with the shutter having inputted the blinking signal blinks the lamp 52a. {See FIG. 11B}.

  In this way, by opening all the open / close doors 43 in a state where the collection container 13 is not stored in the frontage 14, the operator is instructed to install an empty collection container 13, and with a shutter. By the blinking of the lamp 52a of the display device 41, the front door 14 for installing the empty collection container 13 is commanded.

Step-3
In response to a command (a command for directing the open / close door 43) that all the open / close doors 43 are opened and the lamp 52a of the display 41 with shutter blinks, the operator opens the target door 14 in which the lamp 52a is flashing. An empty collection container 13 is set in It should be noted that an empty collection container 13 is not set in the non-target opening 14 to prevent erroneous insertion.

Step-4
The ID code of the ID label 35 of the empty collection container 13 set in the front door 14 is read by the wireless scanner 21, the ID code of the ID label 34 of the front door 14 set is read by the wireless scanner 21, and the controller 15 stores the frontage 14 (number) and the collection container 13 in association with each other. When the linking of all the empty collection containers 13 that have been set is completed, the controller 15 changes the blinking signal of the lamp 52a output to the display with shutter 41 to the extinguished signal, and subsequently all the shutters. A closing signal of the opening / closing door 43 (a command to return to the rear vertical position, that is, a closing command) is output to the auxiliary display 41. As a result, in all the display devices with shutters 41, the lamps 52a are extinguished and the doors 43 are closed {see FIG. 11 (c)}.

Step-5
The operator takes out one product 12 from the storage container 62 and reads the JAN code of the product 12 with the wired scanner 22. When the controller 15 inputs the JAN code, the controller 15 obtains a product code and a product name corresponding to the JAN code, searches the sorting data {FIG. 9 (c)}, sorts the sorting amount (number of sorting) by product, and the frontage. The quantity of the products 12 to be sorted every 14 is obtained and displayed on the sorting display section 67 of the liquid crystal display panel 17.

  The operator confirms the product code and product name of the product 12 taken out, takes out the same product 12 for the number of sorting, reads the JAN code with the wired scanner 22 one by one, and upon completion, “POS inspection complete” The button (touch panel 18) is operated. When the controller 15 counts the read JAN code and inputs an operation signal for the “POS inspection complete” button, it confirms whether or not it matches the product-specific sorting amount (inspection is executed).

Step-6
When the inspection is completed, the controller 15 outputs the opening signal of the door 43, the blinking signal of the lamp 52a, and the quantity data of the product 12 to be input to the shutter-equipped display 41 for sorting the products 12. The display 41 with shutters, which has received these signals and data, opens the door 43, blinks the lamp 52a, and displays the quantity on the digital display 51 {see FIG. 11 (d)}.

Step-7
The worker confirms the display of the display 41 with shutter and the open state of the open / close door 43 and confirms the front door 14 into which the product 12 is put. Then, the confirmed quantity of the product 12 indicated by the digital display 51 of the display 41 with shutter in the frontage 14 is put into the collection container 13, and the completion button switch 52 of the display 41 is pushed. When the controller 15 confirms the operation signal of the completion button switch 52, the controller 15 outputs a closing signal of the open / close door 43 and an extinguishing signal of the lamp 52a to the display 41 with the shutter. As a result, the display with shutter 41 having received these signals and data turns off the lamp 52a and closes the open / close door 43. The display on the digital display 51 is lit as it is {see FIG. 12 (a)}.

  Subsequently, similarly, the operator puts the product 12 into the collection container 13 of the next frontage 14, presses the completion button switch 52, and the controller 15 similarly releases the shutter of the frontage 14 after the introduction is finished. The lamp 52a of the attached indicator 41 is turned off, and the open / close door 43 is closed.

Step-8
Then, when all of the inspected products 12 have been put in, the controller 15 outputs a turn-off signal of the digital display 51 to the shutter-equipped displays 41 in all of the front doors 14 into which the products 12 have been put in, and displays with the shutter. The device 41 turns off the digital display 51 {see FIG. 12 (b)}.

Step-9
If the product 12 still remains in the storage container 62, the operator takes out the next product 12 and reads the JAN code of the product 12 with the wired scanner 22.
Thereby, the above step-5 to step-8 are repeated.

Step-10
When the sorting of all the products 12 in the storage container 62 is completed, the controller 15 outputs an opening signal of the open / close door 43 to all the display devices 41 with shutters in the frontage 14, and all the display devices 41 with shutters are opened and closed. Open the door 43 {see FIG. 12 (c)}.
Thus, by opening all the open / close doors 43 in a state where the collection container 13 is stored in the frontage 14, the operator is instructed to carry out all the stored collection containers 13. The

Step-11
The operator unloads all the collection containers 13 according to a command by opening all the open / close doors 43, puts them into the shipping conveyor device 63, and when finished, presses the “collection container removal completion” button (touch panel 18) is operated. When the controller 15 inputs the operation signal of “collection container removal completion”, the controller 15 outputs a closing signal of the open / close door 43 to all the display devices 41 with shutters in the frontage 14, and all the display devices 41 with shutters open and close. Close the door 43 {return to the state shown in FIG. 11A}.

  As a result of these steps, according to the state of the open / close door 43 and the display state of the display with shutter 41, the sorting operation of the products 12 is executed, and the installation / unloading of the collection container 13 is executed.

  As described above, according to the present embodiment, the opening / closing state of the open / close door 43 provided in each frontage 14 instructs the installation of the collection container 13 to the frontage 14 or the removal from the frontage 14. The worker can recognize when and where the collection container 13 is installed or carried out with respect to the frontage 14, and can improve the work efficiency of the worker.

  Further, according to the present embodiment, when the open / close doors 43 provided in all the front doors 14 are in an open state, and the front doors 14 are all empty at this time, the operator can empty the collection container 13 to the front door 14. It can be recognized that the installation of is instructed, and an empty collection container 13 can be installed. At this time, since the open / close doors 43 of all the front doors 14 are in the open state, the installation work of the collection container 13 to the front doors 14 is facilitated, and workability can be improved.

  Further, according to the present embodiment, when the open / close doors 43 provided in all the front doors 14 are in an open state, and the collection container 13 is stored in the front door 14 at this time, the operator can open the collection container from the front door 14. It can be recognized that the carry-out of 13 is instructed, and the collection container 13 after the sorting of the products 12 can be carried out. At this time, since the open / close doors 43 of all the front doors 14 are in the open state, the work of carrying out the collection container 13 from the front doors 14 becomes easy, and workability can be improved.

  Further, according to the present embodiment, when the open / close doors 43 provided in all the front doors 14 are in an open state and the lamp 52a of the shutter-equipped display 41 corresponding to the front door 14 is in a blinking state (an example of a lighting state), The operator can recognize that the installation of the empty collection container 13 to the mouth 14 is instructed while the lamp 52a of the display 41 with shutter is blinking, and only the mouth 14 where the lamp 52a is blinking, That is, the empty collection container 13 can be installed only in the necessary frontage 14. At this time, since the open / close doors 43 of all the front doors 14 are in the open state, it is easy to install the collection container 13 in the front door 14 where the lamp 52a of the display 41 with the shutter is turned on. In addition, since the collection container 13 is not installed in the frontage 14 where it is not necessary, it is possible to reduce the risk that the product 12 will be erroneously introduced during the sorting operation.

  Further, according to the present embodiment, in order from the collection container 13 in which the amount of the product 12 to be input is large, the predetermined priority opening 14 considering workability, for example, the wired scanner 22 for checking the product 12, and the sorting Workability can be improved by setting the front door 14 that is close to the liquid crystal display panel 17 that displays data related to the data and that allows the product 12 to be loaded and unloaded even if the worker does not move.

  Further, according to the present embodiment, the width in the left-right direction of the opening / closing door 43 is narrower than the width in the left-right direction of the collection container 13, so that there is a risk of contact with the collection container 13 when the opening / closing door 43 is opened / closed. In addition, the collection container 13 can be held without being obstructed by the open / close door when the collection container 13 is taken in and out, and the workability can be improved.

  Further, according to the present embodiment, the second door portion 50 is suspended from the first door portion 49, thereby filling the gap between the first door portion 49 of the plate material and the collection container 13, and visually. In addition, it is possible to prevent the operator from putting the product 12 into the collection container 13. Further, the second door portion 50 is soft with a cloth material, so that even if the operator touches it, it is possible to avoid the risk of being scratched, and the risk of scratching the collection container 13 can be avoided.

  Further, according to the present embodiment, when the opening / closing door 43 opens to the front side from the front door 14, there is a risk of contact with the operator when the opening / closing door 43 opens, but the opening / closing door 43 opens to the back side of the front opening 14. Thus, when the open / close door 43 is opened, it is possible to avoid contact with the operator.

In the present embodiment, the empty collection container 13 is installed in the frontage 14 with all the open / close doors 43 provided in the frontage 14 open, and the lamp of the display 41 with the shutter corresponding to the frontage 14. 52a is in a blinking state, but by opening only the open / close door 43 of the frontage 14 where the collection container 13 is installed, the installation of the collection container 13 in the frontage 14 with the open / close door 43 opened is instructed.

Good.
Thereby, the operator does not install the collection container 13 in the unnecessary frontage 14, thereby reducing the possibility that the product 12 is erroneously inserted during the picking work or from the frontage 14 that does not need to be taken out. By not carrying out the collection container 13, work efficiency can be improved.
In addition, the collection container 13 is instructed to be carried out from the frontage 14 by opening all the opening / closing doors 43 provided in the frontage 14, but the lamp 52a of the display 41 with the shutter corresponding to the frontage 14 blinks. By setting the state (an example of lighting), it is possible to instruct the carry-out of the collection container 13 only from the front door 14 in which the lamp 52a blinks in the front door 14 with the open / close door 43 opened. Thereby, the operator recognizes that the collection container 13 is carried out only from the front door 14 in which the open / close door 43 is opened and the lamp 52a blinks, and is carried out. At this time, since the open / close doors 43 of all the front doors 14 are in the open state, the work for carrying out the front doors 14 in which the lamps 52a are blinked is facilitated, and workability is improved. Moreover, work efficiency can be improved by not carrying out the collection container 13 from the frontage 14 which does not need taking out.

In this embodiment, the sorting door device sorts the products 12 stored in the storage containers 62 conveyed by the cart 61 into the collection containers 13 stored in the front doors 14.
