  However, in the case of a sorting system that puts articles into each frontage of the shelf where the baskets for each store are arranged, the worker can easily grasp whether or not to move to a location where sorting work should be performed. However, since it is necessary to match the infrared light emitting part of the cart with the infrared light receiving part of the shelf, there is a problem that an operator, particularly an unfamiliar worker, cannot work quickly.

  The present invention has been made in view of such circumstances, and provides a technique capable of sorting articles accurately and quickly without extra work.

In order to solve the above problem, a sorting system according to one aspect of the present invention has an article sorting operation information, and an article placed in a movable cart container is based on the sorting operation information. In a sorting system that sorts into each frontage of a sorting shelf having a plurality of identifiable frontages, it is determined that the goods are taken out from the cart container, and that the goods are taken out by the goods removal judgment means. In this case, a control means is provided for controlling so as to notify a slot of an article input destination specified based on the sorting work information among the plurality of slots.
According to the first aspect of the present invention, the worker receives the sorting instruction with the cart, moves to the instructed location, and picks up the article in the container. You can understand at a glance. In other words, the operator can easily check the frontage where the article should be put in without performing any extra operation other than the original operation of putting in and out the sorting (for example, the operation of positioning the cart for infrared communication). Will be able to. Therefore, operability is improved, and sorting work can be performed efficiently. Also, when the worker lifts the item in the container and does the sorting, the worker notifies the frontage where the item should be put in, so other workers are working near the location. In addition, since the thing in the container is taken out after the worker's work is finished, the influence on the sorting work of other workers (such as accidentally throwing an article in accordance with instructions to other workers) Can be reduced as much as possible.
As the article take-out determining means, it is determined that the article is taken out based on the change in the measured value output from the weighing means by taking out the article with the weighing means provided in the lower part where the cart container is arranged. Alternatively, for example, a pair of sensors is provided to block the opening at the top of the container, and when it is determined that the sensor is blocked when the article is taken out, it is judged that the article has been taken out, An imaging unit that captures an image in the container may be provided in the cart, and it may be determined that the article has been removed when the article has been removed and the image has changed more than a certain level.

The sorting system includes a storage unit that stores information for identifying the cart or the worker, and the control unit stores the cart or operation stored in the storage unit as a notification of the frontage slot. Control may be performed so that information for identifying the person is displayed on the display unit at the entrance.
According to the invention of claim 2, since information on workers and carts is displayed at the frontage where goods should be put, even when a plurality of workers are working in the same place, Each worker can easily identify instructions to the worker.

In the sorting system, the article take-out determination unit may be a weighing unit provided at a position where the container of the cart is arranged.
According to the third aspect of the present invention, the measured value always decreases when the article is taken out from the container. Therefore, it can be determined that the article is taken out from the container with a simple configuration.

In the sorting system, a weighing unit is provided at each frontage, a measurement value output from a weighing unit provided at a position where the cart container is disposed, and a measurement output from the measurement unit at the notified frontage. You may make it further provide the correctness determination means which determines the correctness of a sorting operation | work based on a value.
According to the invention of claim 4, it can be easily confirmed that the article taken out from the container has been put into the correct frontage.

In the above sorting system, the control means may perform control so as to reset the measurement value of the measurement means provided in the specified frontage to zero when notifying the frontage.
According to the invention of claim 5, the measured value of the frontage scale is reset to zero at the timing when the article in the container is lifted up, and for example, the article is placed after laying the cushion material inside the container. Even when thrown, since the cushion material is tared, the measured value immediately before the article is put can be set to “0”, so that accurate weighing can be realized.

In the above sorting system, when notifying the frontage, the control means may determine whether or not the frontage is working, and control to notify the frontage that is not performing work.
According to the invention of claim 6, in order to notify the frontage where other workers are not sorting work, even when multiple workers are sorting at the same place at the same time, as instructions to themselves The notification of the frontage and the notification of the frontage as an instruction to other workers do not overlap. Will be able to.

In order to solve the above problem, a sorting system according to another aspect of the present invention has sorting work information on articles, and can identify the articles stored in the article storage shelf based on the sorting work information. In a sorting system that sorts each area of a movable apparatus having a plurality of areas, it is determined that an article is taken out from the article storage shelf, and an article take-out judging means that judges that an article is taken out, and the article take-out judging means determines that the article has been taken out. In this case, control means is provided for controlling so as to notify an input area of an article specified based on the sorting work information among the plurality of areas.
According to the invention of claim 7, even in a so-called picking method in which the articles accommodated in the shelf are sorted into a movable device, when it is determined that the article has been taken out from the shelf, the area of the device to be sorted is notified. Therefore, sorting work can be easily performed.

  According to the present invention, articles can be sorted accurately and quickly without extra work.

  FIG. 5 is an example of a block diagram of a control box 40 that controls the sorting shelf 50. As shown in FIG. 5, the control box 40 includes a CPU 420, a RAM 421, a ROM 422, and a communication unit 424. The communication unit 424 communicates with the sorting shelf 50 having a plurality of frontage and the management apparatus 10. The RAM 421 stores a later-described product file.

  FIG. 6 is an example of a conceptual diagram of a work area to which the sorting system 1 is applied. 7 and 8 are examples of information stored in the management apparatus 10. In the working area to which the sorting system 1 is applied, as shown in FIG. 6, an article storage shelf 60 (a shelf that stores the same article) for each article, and an article temporary table for placing articles on the container 31 of the cart 30. There is a sorting shelf 50.

  The worker a reads, for example, a barcode attached to an opening of the article storage shelf 60 that stores a certain article with the barcode reading unit of the handy terminal. Then, the article identification information of the article is transmitted to the management apparatus 10, the sorting management information file (described later) is referred to, and the total number (described later) of the article is displayed on the display unit of the handy terminal. The worker a confirming the display unit of the handy terminal picks up the displayed items as many as the number of the displayed items, and labels a label on which the item identification information of the items is barcoded (not shown) in the vicinity of the item storage shelf 60. Output from. Then, the worker a puts the article taken out from the article storage shelf 60 into the container 31, attaches a label to the container 31, and places it on the article temporary table.

  Note that the sorting management information file is a file that indicates the number of items ordered by article and by destination, and is a file that the management apparatus 10 generates and stores based on order information from each store. For example, the management apparatus 10 generates and stores a sorting management information file as shown in FIG. The sorting management information file shown in FIG. 7A is associated with the item identification information, and the item name of the item and the total number of orders of all stores of the item (that is, the total number of items inserted into each frontage). The frontage number corresponding to the store where the article is ordered (that is, the frontage number of the destination of the product), the number ordered by the store corresponding to the frontage of the frontage number (that is, to the frontage of the frontage number) The number of inputs) is stored. For example, for the article with the article identification information “0001”, the total number of orders for today is 4, and the breakdown is 2 orders from the store corresponding to the frontage number “1”, and the frontage number “2”. This indicates that the number of orders from the corresponding store is one and the number of orders from the store corresponding to the frontage number “3” is one. The work instruction information shown in FIG. 12 is generated based on the sorting management information file. Further, other files stored in the management apparatus 10 will be described later.

  For example, if the sorting management information file shown in FIG. 7A is stored in the management apparatus 10, when the worker a in FIG. 6 reads the barcode related to the article A, the total number is displayed on the display unit of the handy terminal. Since “4” is displayed, the operator a takes out four articles A from the article storage shelf 60, puts the four articles A taken out from the article storage shelf 60 into the container 31, and labels the label on the container 31. A label relating to the article A output from a printer (not shown) is attached and placed on the article temporary table.

  The worker a similarly works on the articles B to D, and each article is put on the article temporary table, and the container 31 to which the label is attached is placed. The container 31 on the temporary article placement table is placed on the cart 30 by the operator b and moved to the sorting shelf 50 to perform the sorting operation. Details will be described later.

  Next, files other than the sorting management information file stored in the management apparatus 10 will be described. The management apparatus 10 stores in advance a cart file related to the position where the container 31 of the cart 30 is arranged. For example, the management apparatus 10 stores a cart file as shown in FIG. The cart file shown in FIG. 7B is associated with a cart number (cart identification information) for identifying the cart 30, container position information indicating the arrangement position of the container 31 at the lower rear of the cart 30, and the cart 30. Container position information indicating the arrangement position of the container 31 in the lower front part, Container position information indicating the arrangement position of the container 31 in the upper rear part of the cart 30, and the container position indicating the arrangement position of the container 31 in the upper front part of the cart 30 I remember information.

  In addition, the management device 10 stores in advance a scale file indicating the relationship between the arrangement position of each container 31 and the scale. The cart 30 receives the scale file from the management device 10 or stores it in advance. For example, the management device 10 stores a scale file as shown in FIG. The scale file shown in FIG. 7C stores a scale number for identifying the platform scale included in the cart 30 and container position information in association with each other. That is, for example, the arrangement position of the container 31 in the lower rear part of the cart 30 with the cart number “10” is identified by the container position information “0011”, and the container 31 arranged at the arrangement position has the scale number “0011”. Weighed with a scale. A label in which the container position information of each arrangement position is converted into a barcode is attached to each arrangement position of the container 31 of the cart 30.

Further, the management device 10 stores a work file for specifying the work of the worker b in FIG. 6 (work for placing the container 31 for each article on the cart 30) in the temporary article placement table. That is, the work file is a file for identifying an article placed on the cart 30. For example, the management apparatus 10 stores a work file as shown in FIG. The work file shown in FIG. 7D stores container position information and article identification information in association with each other.
The work file is stored on a label (label affixed by the operator a) attached to the side of the container 31 when the operator b places the container 31 for each article on the cart 30 in the article temporary table. When the barcode and the barcode on the label affixed to the container placement position on which the container 31 is placed on the cart 30 are read, both barcode information is transmitted to the management device 10, and the management device 10 Bar codes are associated and stored in the work file. Note that the worker b reads the barcodes of the containers 31 (four containers 31 in the example of FIG. 2) for one cart in the temporary article storage table.

In addition, the management device 10 stores a cart worker file for identifying the worker b who is using the cart 30. For example, the management apparatus 10 stores a cart operator file as shown in FIG. The cart worker file shown in FIG. 7E stores a cart number and a worker number for identifying the worker b in association with each other.
The cart worker file is a screen (screen with a worker number input field) displayed on the first display unit 306 or the first display unit 307 of the cart 30 when the worker b uses the cart 30. ), The cart number of the cart 30 stored in the RAM 321 of the cart 30 and the worker number input by the worker b are transmitted to the management apparatus 10 when the worker number is input. The management device 10 stores each piece of information in association with each other.

  In addition, the management device 10 stores a location file related to the location of the sorting shelf 50 in advance. For example, the management device 10 stores a location file as shown in FIG. The location file shown in FIG. 8A is associated with a location number that identifies a location, a frontage number belonging to the location, a display number displayed on the frontage display unit of the frontage number, and a frontage number of the frontage number. A frontage balance number for identifying the balance is stored. As shown in FIG. 6, the location file shown in FIG. 8 (b) stores that there are frontage 1, 2, 6, 7 in location 1 and frontage 3, 4, 8, 9 in location 2. ing. Further, it is stored that the number displayed on the frontage indicator of the frontage number “1” is the display number “1”, and the frontage scale of the frontage is the frontage scale number “1” (the same applies to the other frontage). ).

In addition, the management device 10 stores a product file related to the weight of each product in advance. Further, the cart 30 and the control box 40 receive the product file from the management apparatus 10 and store them in the RAM 321 of the cart 30 and the RAM 421 of the control box 40.
For example, the management device 10, the cart 30, and the control box 40 store a product file as shown in FIG. The product file shown in FIG. 8B stores the article name, weight, and the like in association with the article identification information. The management device 30 transmits the updated product file to the cart 30 and the control box 40 when the product file is updated.

  Next, the operation of the sorting system 1 will be described using a flowchart. FIG. 9 is a flowchart showing an example of the operation of the cart 30, from the input of the worker number in one cart 30 to the completion of the insertion of articles (all articles) in all containers 31 of the cart 30. It is a flowchart which shows this operation | movement. FIG. 10 is a flowchart showing an example of the operation of the management apparatus 10, from the receipt of the worker number from one cart 30 to the completion of the insertion of articles (all articles) in all containers 31 of the cart 30. It is a flowchart which shows this operation | movement. FIG. 11 is a flowchart showing an example of the operation of the control box 40. Upon receipt of confirmation button blinking instruction information (described later) related to an article (one article) in the container 31 of the cart 30 from the management apparatus 10. 4 is a flowchart showing the operation from when the input confirmation information (described later) is transmitted to the management apparatus 10. FIG. 12 is an example of work instruction information generated based on the sorting management information file. FIG. 13 is an example of instruction information displayed on the first display unit 306 and the second display unit 307 of the cart 30.

  In FIG. 9, when the worker b inputs the worker number on the screen displayed on the first display unit 306 (the screen with the worker number input field), the cart 30 includes the cart number of the cart 30 together with the cart number. The worker number is transmitted to the management apparatus 10 (step S101). Subsequently, the cart 30 initializes an area for temporarily storing work instruction information (step S102).

  Subsequently, when the cart 30 reads the barcode on the label affixed to the container 31 and the barcode on the label affixed to the container arrangement position where the container 31 is placed, the cart 30 At the same time, the article identification information and the container position information are transmitted to the management apparatus 10 (step S103). The cart 30 shown in FIG. 2 can load four containers 31 at the same time. Therefore, when four containers 31 are loaded, four sets of article identification information and container position information are set. 10 to send.

  For example, as shown in FIG. 6, the worker b who uses the cart 30 with the cart number “10” places the container 31 in which the article with the article name “A” is placed at the container placement position in the lower rear part, and the article name The container 31 in which the article “B” is placed is placed at the container placement position in the lower front part, the container 31 in which the article “C” is placed is placed in the container placement position in the upper rear part, and the article name “D”. The container 31 in which the article is placed is placed at the container arrangement position in the upper front part, and the barcode on the label attached to each container 31 and the barcode on the label attached to each container arrangement position are read. In this case, the cart 30 includes a set of article identification information “0001” and container position information “0011”, a set of article identification information “0002” and container position information “0012”, and an article identification information “0”. 03 "and a pair of container position information" 0013 ", to send a set of container position information with the article identification information" 0004 "," 0014 ".

  The cart 30 manages start information indicating that sorting is started together with the cart number when the operator b presses the start button on the screen displayed on the first display unit 306 (screen having the start button), for example. It transmits to the apparatus 10 (step S104).

  The cart 30 that has transmitted the start information receives the work instruction information from the management apparatus 10 and temporarily stores it (step S105). Subsequently, the cart 30 generates instruction information for each location and each article based on the temporarily stored work instruction information (step S106). For example, the cart 30 receives the work instruction information shown in FIG. 12 in step S105, and generates, for example, instruction information for each location and each article shown in FIGS. 13 (a) to 13 (f). 13A shows the location information “1” and the product “A”, FIG. 13B shows the location “1” and the product “B”, and FIG. 13C shows the location “1”. The instruction information of the article “C”, FIG. 13D is the instruction information of the location “1” and the article “D”, FIG. 13E is the instruction information of the location “2” and the article “A”, and FIG. (F) is the instruction information of the location “2” and the article “D”.

  Subsequently, the cart 30 displays one piece of instruction information for each location and each item generated in step S106 on the first display unit 306 and the second display unit 306 (step S107). For example, when the cart 30 generates the instruction information for each location and each article shown in FIGS. 13A to 13F in step S106, for example, FIG. 13A in step S107 executed for the first time. The instruction information of the location “1” and the article “A” shown in FIG. 13 is displayed, and the instruction information of the location “1” and the article “B” shown in FIG. ... In step S107 executed for the sixth time, the instruction information of the location “2” and the article “D” shown in FIG. 13 (f) is displayed.

  Subsequently, the cart 30 determines whether or not the article has been taken out from the container 31 (step S108 / article take-out determining means). Specifically, the cart 30 determines that the article has been taken out from the container 31 when detecting a decrease in the measured value of any of the platform scales 301 to 304. If the cart 30 determines that the article has not been removed from the container 31 (step S108: No), the cart 30 repeatedly executes the same process (step S108) until it is determined that the article has been removed from the container 31.

  When the cart 30 determines that the article has been taken out from the container 31 (step S108: Yes), the weight reduction value of the container 31 from which the article has been taken out (that is, a decrease in the total weight of the articles placed in the container 31). Amount) is measured (step S109).

  Subsequent to step S109, the cart 30 transmits the cart number and the container position information of the container 31 determined to have been taken out and the weight loss value measured in step S109 to the management apparatus 10 (step S110). For example, when the cart 30 detects a decrease in the measurement value by the platform balance 301 (a platform scale for weighing the container 31 at the lower rear container arrangement position), the cart position information “0011” at the lower rear container arrangement position and the platform scale The weight loss value calculated from the difference between the previous measurement value and the current measurement value is transmitted to the management apparatus 10.

  Following step S110, the cart 30 determines whether error information has been received from the management apparatus 10 (step S111). If the cart 30 determines that the error information has not been received (step S111: No), has it received from the management device 10 all the article insertion completion information indicating that all the articles related to the work instruction information have been input? It is determined whether or not (step S112). When the cart 30 determines that the all-article input completion information has been received (step S113: Yes), the cart 30 outputs that all articles have been normally input (step S114). Then, the flowchart relating to the cart 30 ends.

  On the other hand, when it is determined that the cart 30 has not received all the article input completion information (step S112: No), the management apparatus 10 supplies the article switching instruction information for instructing that the article to be input should be switched from the management apparatus 10. It is judged whether it received from (step S113). If the cart 30 determines that the article switching instruction information has not been received (step S113: No), the cart 30 returns to step S108. That is, the cart 30 returns to step S108 and operates in the same manner for the articles being displayed on the first display unit 306 and the second display unit 307.

  If the cart 30 determines that the article switching instruction information has been received (step S113: Yes), the cart 30 returns to step S107. That is, the cart 30 returns to step S107 and operates in the same manner for other articles related to the work instruction information.

  On the other hand, when the cart 30 determines that the error information has been received (step S111: Yes), the cart 30 notifies a warning that the article has not been correctly inserted into the frontage (step S115). For example, if the cart 30 determines that the error information has been received while the instruction information for the location “1” and the article “A” shown in FIG. 13A is displayed, the article “A” is inserted into the frontage. A warning to the effect that it has not been made is notified by any one or more of the first display unit 306, the second display unit 307, and the speaker 310. Then, the flowchart relating to the cart 30 ends.

  In FIG. 10, the management apparatus 10 receives the worker number together with the cart number from the cart 30 (step S131). Subsequently, the management device 10 initializes an area for temporarily storing information related to the cart 30 (step S132). For example, the management apparatus 10 stores the cart number and the worker number in association with each other in the cart work file and temporarily stores the information in association with the cart number in the subsequent steps (work instruction information, article identification information, container position). Information, weight loss value, weight increase value, article-by-item loading completion information, etc.) are temporarily initialized.

  Subsequently, the management apparatus 10 receives the item identification information and the container position information together with the cart number from the cart 30 and temporarily stores them in the area initialized in step S132 (step S133). As a result, the management apparatus 10 can identify each container arrangement position, that is, what the article placed on each of the platform scales 301 to 304 is.

  The management apparatus 10 receives start information from the cart 30 together with the cart number (step S134). The management apparatus 10 that has received the start information together with the cart number refers to the sorting management information file and the location file based on the article identification information received in step S133, generates work instruction information, and generates the generated work instruction information. The data is transmitted to the cart 30 and temporarily stored in the area initialized in step S132 (step S135).

  For example, in step S133, the management apparatus 10 sets a set of the item identification information “0001” and the container position information “0011”, a set of the item identification information “0002” and the container position information “0012” together with the cart number “10”. When the set of the item identification information “0003” and the container position information “0013” and the set of the item identification information “0004” and the container position information “0014” are received, the sorting management information file shown in FIG. With reference to the location file shown in (a), for example, work instruction information shown in FIG. 12 is generated, and the generated work instruction information is transmitted to the cart 30 with the cart number “10” and temporarily stored in the initialized area. To do.

  Subsequent to step S135, the management apparatus 10 receives the container position information and the weight loss value from the cart 30 together with the cart number (step S136). The management apparatus 10 that has received the container position information and the weight loss value together with the cart number refers to the information received and temporarily stored in step S133 (correspondence relationship between the container position information and the item identification information), and the weight loss of any item. If the value is received, that is, the article taken out in step S108 of the cart 30 is specified, the cumulative value of the weight loss value is temporarily stored in association with the article identification information (step S137).

  Subsequently, the management device 10 specifies a frontage (one or more) into which the article taken out in step S108 of the cart 30 is put (step S138). Specifically, the management device 10 refers to the sorting management information file or the work instruction information, and identifies the frontage (one or more) for inserting the article identified in step S137.

  Subsequently, the management apparatus 10 includes confirmation button blinking instruction information for instructing that the confirmation button should blink, including the worker number stored in step S132 and the frontage number (one or more) specified in step S138. The data is transmitted to the control box 40 (step S139 / control means). In other words, the management device 10 displays a notification command to notify the frontage (one or more) that is the sorting destination of the article from among a plurality of frontage by displaying the worker number and blinking the confirmation button. Send to.

  Subsequently, the management apparatus 10 transmits measurement value zero reset instruction information to the control box 40 that indicates that the measurement value of the frontage scale should be zero-reset, including the frontage number (1 or more) specified in step S138. (Step S140 / control means).

  Subsequently, the management device 10 receives the frontage number, the item identification information, and the weight increase value from the control box 40 (step S141). The management apparatus 10 that has received the frontage number, the item identification information, and the weight increase value temporarily stores the weight increase value (cumulative value) in association with the item identification information for each frontage number (step S142).

  Subsequently, the management apparatus 10 determines whether or not a predetermined number of articles have been inserted for each frontage into which the article is to be inserted (step S143 / correction determination unit). Specifically, the management apparatus 10 refers to the product file, the work instruction information, and the information stored in step S142, and inputs the article, that is, the front door that is the input destination of the article taken out in step S108 of the cart 30. When the weight increase value is a weight value corresponding to a predetermined number to be inserted into the frontage for the article, it is determined that a predetermined number of the articles have been input for the frontage. For example, the management apparatus 10 determines that the weight increase value related to the front door “1”, which is one of the input destinations of the product “A” (unit weight 500 g), is to be supplied to the front door “1” for the product “A”. When the weight value for “2” is “1000 (g)”, it is determined that a predetermined number “2” of articles “1” has been introduced for the opening “1” into which the article “A” should be placed.

  When the management apparatus 10 determines that the predetermined number of articles has not been placed in any of the frontage where the article is to be placed (step S143: No), the management apparatus 10 returns to step S136. When the management apparatus 10 determines that a predetermined number of articles have been inserted into any of the frontage to which the article is to be input (step S143: Yes), the management apparatus 10 sets the frontage number (one or more) determined to have been input with the predetermined number. The confirmation button lighting instruction information for instructing that the confirmation button should be turned on is transmitted to the control box 40 (step S144 / control means).

  Subsequently, the management apparatus 10 determines whether or not the input confirmation information indicating that the worker b has confirmed the completion of the input operation of the article has been received from the control box 40 (step S145). When the management apparatus 10 determines that the input confirmation information has not been received (step S145: No), the management apparatus 10 returns to step S136. When the management apparatus 10 determines that the input confirmation information has been received (step S145: Yes), the management apparatus 10 stores the cumulative weight loss value stored in step S137 and the cumulative weight increase value stored in step S142 (each frontage Is determined to be equal to or not (step S146 / correction determination means). In other words, the management apparatus 10 determines whether or not the cumulative weight value taken out from the container 31 and the cumulative weight value put into all corresponding frontage for the article match. That is, the correctness of the sorting operation for the article is determined.

  For example, the management device 10 stores the cumulative weight loss value “2000 g” for the article “A” (unit weight 500 g) (step S137), and stores the cumulative weight increase value “1000 g” for the frontage “1” ( In step S142), the cumulative weight increase value “500 g” for the frontage “2” is stored (step S142), and the cumulative weight increase value “500 g” for the frontage “3” is stored (step S142). It is determined that the weight loss value “2000 g” matches the cumulative weight increase value (the total value “2000 g” of the cumulative weight increase values of the frontage “1”, the frontage “2”, and the frontage “3”).

  When the management device 10 determines that the cumulative weight loss value and the cumulative weight increase value (total value of each frontage) match (step S146: Yes), the temporary storage information of the article stored in step S137 and step S142 is stored. At the same time as initialization, the completion information for each article indicating that the introduction of the article has been completed is stored (step S147). Subsequently, the management device 10 refers to the work instruction information and the article-by-article completion information, and determines whether or not the introduction of all articles according to the work instruction information has been completed (step S148).

  When the management apparatus 10 determines that all the articles related to the work instruction information have not been input (step S148: No), the management apparatus 10 transmits the article switching instruction information to the cart 30 (step S149), and returns to step S136. That is, the management apparatus 10 returns to step S136 and operates in the same manner for other articles related to the work instruction information.

  When the management apparatus 10 determines that all the articles related to the work instruction information have been input (step S148: Yes), the management apparatus 10 transmits all the article input completion information to the cart 30 (step S150). Then, the flowchart relating to the management apparatus 10 ends.

  On the other hand, if the management device 10 determines that the cumulative weight loss value and the cumulative weight increase value (total value of each frontage) do not match (step S146: No), it transmits error information to the cart 30 (step S151). . Then, the flowchart relating to the management apparatus 10 ends.

  In FIG. 11, the control box 40 receives confirmation button blinking instruction information including a frontage number (1 or more) frontage number together with the worker number from the management apparatus 10 (step S161). The control box 40 that has received the confirmation button blinking instruction information together with the worker number displays the worker number and the confirmation button blinking for the frontage number (one or more) included in the confirmation button blinking instruction information. 50 (step S162 / control means). For example, the control box 40 transmits a worker number display command including a frontage number and a confirmation button blinking command to the sorting shelf 50. As a result, the worker number is displayed on the display section of the frontage number, and the confirmation button for the frontage number blinks.

  Subsequently, the control box 40 receives the measurement value zero reset instruction information including the frontage number (1 or more) of the frontage number from the management device 10 (step S163). The control box 40 that has received the measurement value zero reset instruction information controls the sorting shelf 50 to zero-reset the measurement value of the frontage scale for each corresponding frontage (one or more) (step S164 / control means). For example, the control box 40 transmits a weighing value zero reset command including the frontage number to the sorting shelf 50. Thereby, the frontage scale of the frontage of the frontage number is reset to zero. For example, when a cushion material is used as a rug on the bottom of a container for a fragile article, the measured value including the cushion material is “0”. Therefore, the input article can be accurately measured.

  Subsequently, the control box 40 determines whether or not an article has been placed in the front of the sorting shelf 50 (step S165). Specifically, when the control box 40 detects an increase in the measured value of the frontage scale of any frontage of the sorting shelf 50, the control box 40 determines that an article has been put into the frontage of the sorting shelf 50. If the control box 40 determines that no article has been inserted into the front of the sorting shelf 50 (step S165: No), the control box 40 performs the same processing (step S165) until it is determined that an article has been inserted into the front of the sorting shelf 50. Run repeatedly.

  When the control box 40 determines that an article has been inserted into the front edge of the sorting shelf 50 (step S165: Yes), the control box 40 increases the weight of the article input into the front edge (that is, the frontage scale determined that the article has been input). Measured value) is measured (step S166).

  Subsequently, the control box 40 refers to the product file, and specifies the input article based on the weight increase value (step S167). Subsequently, the control box 40 transmits the article identification information of the article specified in step S167 and the weight increase value measured in step S166 to the management apparatus 10 together with the frontage number determined that the article has been inserted (step S167). Step S168).

  Subsequently, the control box 40 receives confirmation button lighting instruction information including a frontage number (one or more) of frontage numbers from the management device 10 (step S169). The control box 40 that has received the confirmation button lighting instruction information controls the sorting shelf 50 to light the confirmation button for each corresponding frontage (one or more) (step S170 / control means). For example, the control box 40 transmits a confirmation button blink command including the frontage number to the sorting shelf 50. Thereby, the confirmation button of the frontage number corresponding to the frontage number switches from blinking to lighting.

  Note that when the worker b puts a predetermined number of articles into the frontage, the confirmation button while the frontage is lit is pressed as a confirmation work. When the confirmation button is pressed, the sorting shelf 50 transmits confirmation button pressing information including the frontage number to the control box 40.

  When the confirmation button pressing information is received from the sorting shelf 50, that is, when the operator b presses the front-facing confirmation button lit in step S170, the control box 40 displays the worker number displayed in the front door. The sorting shelf 50 is controlled to be erased and to turn off the confirmation button for the frontage (step S171 / control means). For example, the control box 40 transmits an operator number deletion command including a frontage number and a confirmation button turn-off command to the sorting shelf 50. As a result, the worker number in the display section at the frontage of the frontage number is erased, and the confirmation button at the frontage of the frontage number is switched from lighting to off.

  The control box 40 determines whether or not the sorting shelf 50 has been controlled so as to erase all the worker numbers at the frontage where the worker numbers have been displayed and to turn off all the confirmation buttons that have been turned on ( Step S172). In other words, the control box 40 determines whether or not the worker b has put a predetermined number into all the frontage where the article is to be placed, and has pressed the confirmation button for all frontage as the confirmation work.

  When the control box 40 determines that the sorting shelf 50 is not controlled to erase all the worker numbers at the front doors and turn off all the confirmation buttons (step S172: No), the process returns to step S165. When the control box 40 determines that the sorting shelf 50 has been controlled to erase all worker numbers at the front doors and turn off all confirmation buttons (step S172: Yes), it manages the input confirmation information related to the article. It transmits to the apparatus 10 (step S173). Then, the flowchart relating to the control box 40 ends.

  In step S107 of FIG. 9, the cart 30 generates instruction information for each location and each item as information based on the work instruction information, and displays it on the first display unit 306 and the second display unit 306. However, the cart 30 may display the work instruction information on the first display unit 306 and the second display unit 306.

  In step S139 in FIG. 10, the management apparatus 10 transmits confirmation button blinking instruction information together with the worker number to the control box 40. In step S162 in FIG. 11, the control box 40 displays the worker number and confirms the confirmation button. Although the sorting shelf 50 is controlled so as to blink, the management device 10 transmits confirmation button blinking instruction information to the control box 40 together with the cart number, and the control box 40 displays the cart number and blinks the confirmation button. The sorting shelf 50 may be controlled.

  In the flowcharts of FIGS. 9, 10, and 11, an example of work that focuses on one worker is shown. Usually, however, since a plurality of workers perform sorting work at the same time, the management device 10 has a frontage. When notifying, it is preferable to determine whether or not the frontage is in operation, and to perform control so as to notify the frontage where work is not performed.

  Specifically, for example, in the location file shown in FIG. 8A, a flag (“1 (sorting work in progress) is associated with each frontage number and indicates whether or not sorting work is being performed at the frontage of the frontage number. ) / 0 (not being sorted) ", initial value" 0 (not being sorted) ") is stored.

  In the management apparatus 10, when the frontage number, the item identification information, and the weight increase value are received from the control box 40 (step S141 in FIG. 10), the flag “1 (sorting work in progress) is associated with the frontage number. Is stored) (that is, the flag “0” is rewritten to the flag “1”). When the management apparatus 10 transmits the work instruction information to the cart 30 (step S135 in FIG. 10), the management apparatus 10 stores the instruction information related to the frontage that is not being sorted in the cart 30 based on the value of the flag in the location file. Control is performed so that the first display unit 306 and the second display unit 306 are displayed.

  For example, the management apparatus 10 stores the flag “1 (sorting is in progress)” in association with the frontage number “1” in the location file, and the flag “0 (sorting) in association with the frontage number“ 2 ”. Is not in operation) ”is stored, the frontage number that is not in the sorting work is used in place of the instruction information that indicates the frontage numbers“ 1 ”and“ 2 ”shown in FIG. Instruction information (not shown) instructing only “2” as the input destination is displayed, and control is performed to prohibit display of the frontage number “1”. More specifically, for example, the management device 10 generates work instruction information including the value of each frontage number flag stored in the location file, and transmits and stores the work instruction information to the cart 30 (step S135 in FIG. 10). Based on the value of the flag included in the work instruction information, the cart 30 generates the instruction information for each location and each article related to the front of the flag “0 (not sorting)” (step S106 in FIG. 9). ) And display (step S107 in FIG. 9).

  In addition, when the confirmation button for a certain frontage is pressed and turned off (step S170 in FIG. 11), the management apparatus 10 receives information indicating that the confirmation button for the frontage is turned off from the control box 40, and The flag “0 (not being sorted)” is stored in the location file in association with the frontage number (that is, the flag “1” is rewritten to the flag “0”).

Further, when the confirmation button for a certain frontage is pressed and turned off (step S170 in FIG. 11), the management apparatus 10 stores the flag “0 (not sorting)” in the location file in association with the frontage number. In addition, the cart 30 that prohibits the display of the instruction information related to the frontage number is controlled to display the instruction information related to the frontage number. More specifically, for example, when the management apparatus 10 receives information indicating that a certain front door confirmation button has been turned off, the management device 10 includes a work including the flag value of each front door number generated and stored in step S135 of FIG. Refers to the instruction information, and causes the cart 30 that prohibits the display of the instruction information related to the frontage number to display the instruction information related to the frontage number (cancel the display of the instruction information related to the frontage number) The cart 30 generates instruction information for each location and each item related to the frontage based on the information (step S106 in FIG. 9) and displays it (step S107 in FIG. 9).
In the previous example, the display of the frontage number “1” is prohibited. However, when the work of another worker is completed, the information for prohibiting the display of the instruction information related to the frontage number as described above is stored in the cart. 30 and the instruction information regarding the frontage number “1” is displayed. In addition, the timing when the instruction information of the frontage number “1” is additionally displayed in the example may be displayed during the work of the frontage number “2”, or the work of the frontage number “2” is completed. It may be displayed when the confirmation button is pressed.

  In this way, the frontage where other workers are not performing sorting work is notified, so even if multiple workers are sorting at the same place at the same time, the frontage notification is given as an instruction to itself. And the notification of the frontage as instructions for other workers do not overlap, so that erroneous input that can occur when notifications to multiple people are mixed can be suppressed, and sorting work can proceed efficiently Become.

Instead of the management device 10, the control box 40 may be controlled to notify a frontage where work is not performed. For example, in FIG. 11, the control box 40 controls the sorting shelf 50 to display the worker number and blink the confirmation button for one worker (step S162 in FIG. 11), and then all the frontages are displayed. Until it is determined that the sorting shelf 50 has been controlled to erase the worker number and to turn off all the confirmation buttons that have been lit (step S172 in FIG. 11: Yes), the workers of other workers When the confirmation button blinking instruction information is received together with the number from the management apparatus 10 (step S161 in FIG. 11), after the above determination, the worker number is displayed and the confirmation button is blinked for other workers. The shelf 50 may be controlled. For example, the control box 40, while notifying the frontage 1 and the frontage 2 shown in FIG. 6 to one worker, the frontage number “1” together with the worker number relating to another worker from the management device 10. When the confirmation button blink instruction information including “2” and “6” is received, first, the frontage 6 is notified to other workers, and both the frontage 1 and the frontage 2 are notified to one worker. Is completed (after erasing the worker number and turning off the confirmation button), the frontage 1 and the frontage 2 are notified to other workers. In addition, in the above-described example, the control box 40 is configured so that after the notification of both the frontage 1 and the frontage 2 for one worker is completed and the notification of the frontage 6 for other workers is finished, For example, the frontage 1 and the frontage 2 may be notified. In the above example, the control box 40 notifies the other workers of the frontage 1, the frontage 2, and the frontage 6 after the notification of both the frontage 1 and the frontage 2 for one worker is completed. Also good. In the above example, the control box 40 first notifies the frontage 6 to other workers, and when the notification of either the frontage 1 or the frontage 2 for one worker is completed, the control box 40 For example, the frontage for which one worker is finished may be notified to other workers for every frontage for which the notification to one worker is finished.
As described above, when the control box 40 receives the notification command related to the sorting work of another worker while receiving the notification command related to the sorting work of one worker, You may make it alert | report according to the alerting | reporting command which concerns on the said other worker after the alerting | reporting which concerns on an operator is complete | finished.

  In FIG. 11, when the operator b presses the confirmation button, the control box 40 receives the confirmation button pressing information from the sorting shelf 50 and deletes the worker number displayed in the frontage. Although the sorting shelf 50 is controlled to turn off the frontage confirmation button (step S171), when the worker b presses the confirmation button, the sorting shelf 50 itself erases the worker number and turns off the confirmation button. It is good also as an aspect. When the sorting shelf 50 itself erases the worker number and turns off the confirmation button, the sorting shelf 50 relates to the article when all the worker numbers are erased and all the confirmation buttons are turned off. The input confirmation information may be transmitted to the control box 40, and the control box 40 may transmit the input confirmation information to the management apparatus 10.

As described above, according to the above-described embodiment, articles can be sorted accurately and quickly without extra work.
That is, the worker b receives a work instruction from the cart 30, moves to the instructed location, and picks up the article in the container 31. Can be seen at a glance. That is, the operator b can easily insert the article without performing any extra operation (for example, the operation of aligning the cart 30 for infrared communication) other than the original article insertion / removal operation. Will be able to confirm. Therefore, operability is improved, and sorting work can be performed efficiently. In addition, when the worker b lifts the article in the container and sorts the article, the worker notifies the frontage where the article should be put in, so that another worker is working near the location. In this case, since the thing in the container is taken out after the work of the worker is finished, the influence on the sorting work of the other worker (incorrectly throwing the article according to the instruction to the other worker) Etc.) can be reduced as much as possible.
In addition, since the frontage is provided with the measuring unit, it is possible to easily confirm that the correct quantity of articles has been put into the frontage.
In addition, the weighing value of the frontage scale is reset to zero at the timing when the article in the container 31 is lifted, and the weighing value immediately before the item is taken out can be set to “0”. It becomes possible to realize weighing.

  In addition, since the worker number is displayed at the frontage where the article should be placed, each worker can easily give instructions to himself / herself even when a plurality of workers are working in the same place. Can be identified.

The sorting system 1 can also be described as follows.
That is, the sorting system 1 includes a management device that manages the sorting operation of articles, a control device 40 that controls a sorting cart 50 that includes a container 30 on which articles are placed and is movable, and a plurality of frontages. A sorting system including
The management device 10 is a classification management information storage unit that stores classification management information, which is information generated based on an order, in which article identification information for identifying an article is associated with frontage identification information for identifying the frontage. And placement information receiving means (step S134) for receiving placement information including the article identification information relating to the article placed in the container from the cart 30, and the placement information receiving means is the placement information Is received at the sorting destination of the article placed in the container based on the sorting management information stored in the management information storage means and the preceding placement information received by the preceding placement information receiving means. Work instruction information transmitting means (step S135) for identifying the frontage and transmitting work instruction information including the frontage identification information relating to the specified frontage to the cart 30; Weight information receiving means (step S136) for receiving weight information including weight reduction information indicating that the total weight of articles placed on the antenna has been reduced from the cart 30, and the weight information receiving means is the weight reduction information. A notification command transmission means for transmitting to the control device a notification command including the frontage identification information relating to the frontage, which is a sorting destination of the articles placed in the container. Step S139)
The cart 30 includes a placement information transmission unit (step S103) that transmits the placement information to the management device 10, and a work instruction information reception unit (step S105) that receives the work instruction information from the management device 10. When the work instruction information receiving means receives the work instruction information, the work instruction information display means (step S107) for displaying the work instruction information or information based on the work instruction information is placed on the container. Container weighing means for weighing the total weight of the articles (step S109), and weight information transmission for transmitting the weight information including the weight reduction information to the management apparatus 10 when the measured value by the container weighing means decreases. Means (step S110), and the control device 40 receives the notification command from the management device 10. When the means (step S161) and the command receiving means receive the notification command, the frontage notification means for notifying the sorting shelf 50 of the frontage identified by the frontage identification information included in the notification command ( Step S162).

  In the sorting system 1, the weight information transmission means of the cart 30 adds cart 30 identification information for identifying the cart 30 in addition to the weight reduction information or worker identification for identifying a worker who works using the cart 30. The weight information including information is transmitted to the management device 10, and the notification command transmission means of the management device 10 is configured such that the weight information reception means adds the cart 30 identification information or the worker identification information in addition to the weight reduction information. When the weight information including the front door identification information is received, the notification command including the cart 30 identification information or the worker identification information is transmitted to the control device 40 in addition to the front door identification information. The notification means includes the notification instruction in which the command receiving means includes the cart 30 identification information or the worker identification information in addition to the frontage identification information. Is received, the sorting shelf 50 is notified of the frontage identified by the frontage identification information included in the notification command, and the cart 30 identification information or the worker is displayed on the frontage display unit. The identification information may be displayed.

  In the sorting system 1, the sorting shelf 50 includes the frontage weighing means (step S166) for measuring the total weight of the articles sorted into the frontage, and the weight including increase amount information indicating the increase amount of the total weight. Weight information transmission means (step S168) for transmitting information, and the weight information transmission means of the cart 30 replaces or adds to the weight decrease information when the measured value by the container weighing means decreases. The weight information including the decrease amount information indicating the decrease amount of the total weight of the articles placed in the container is transmitted to the management device 10, and the management device 10 transmits the weight transmitted from the cart 30. The right / wrong judgment for comparing the weight reduction information included in the information and the weight increase information included in the weight information transmitted from the sorting shelf 50 to determine whether the sorting work is correct or incorrect Means may further have a (step S146).

  In the sorting system 1, the management device 10 transmits a zero reset command transmission that transmits, to the control device 40, a command for resetting the measurement value by the frontage weighing unit when the notification command transmission unit transmits the notification command. (Step S140), and the command receiving means of the control device 40 causes the sorting shelf 50 to perform zero reset of the measurement value when receiving the zero reset command (zero reset means ( Step S164) may be further included.

  Further, in the sorting system 1, the frontage notifying unit of the control device 40 has the frontage identified by the frontage identification information included in the notification command related to the sorting work of one worker on the sorting shelf 50. When the command receiving means receives the notification command related to the sorting work of another worker while the notification is being notified, the other worker is notified after the frontage related to the one worker is notified. You may make it alert | report the said frontage concerning.

  In the above-described embodiment, the management device 10 compares the amount of articles taken out from the cart 30 (cumulative weight loss) with the amount input to the sorting shelf 50 (cumulative weight gain) for each article in the work instruction information. However, the correctness / incorrectness of the sorting work is determined for each article in the work instruction information (step S146), but the correctness / incorrectness of the sorting work may be determined in units of the work instruction information (collectively for all articles). Good.

  In the above embodiment, as described above, the management device 10 determines whether the sorting work is correct for each article in the work instruction information (step S146), but instead of the management device 10, a control box is used. 40 may determine whether the sorting work is correct or not for each article or work instruction information unit of the work instruction information.

  In the above embodiment, whether the sorting work is correct or not is determined for each article and frontage in the work instruction information (step S143), and then whether the sorting work is correct for each article in the work instruction information is determined. However, it is possible to omit either or both of correctness determination (step S146). In the case where both correct / incorrect determinations are omitted, the cart 30 may simply transmit the fact that the weight has been reduced to the management device 10 without measuring the weight loss value.

  Moreover, in the said embodiment, although the sorting system 1 is set as the structure provided with the control box 40 which controls the sorting shelf 50, the management apparatus 10 or the sorting shelf 50 is good also as a structure which combines the various functions of the control box 40. .

Moreover, in the said embodiment, although the example of the sorting mode (seed method) which takes out articles | goods from each container 31 according to articles | goods and puts into the frontage for every store was demonstrated, from each shelf of the article | item storage shelf for every article | item. The present invention may also be applied to a sorting mode (pick-up method) in which articles are taken out and put into containers for each cart store. For example, when the sorting system 1 determines that an article is taken out from the article storage shelf 60, and the article take-out judging means determines that the article is taken out by the article take-out judging means, the sorting system 1 You may make it provide the control means which controls to alert | report the container of a charging destination.
Specifically, as an article take-out determining means, a scale is provided at each frontage of the article storage shelf, and a container in which the article is placed is placed on the scale. Then, when the worker takes out the article from the container based on the work instruction, the measurement value output from the frontage scale decreases, so the work set in advance based on the signal that the measurement value has decreased. You may make it identify the sorting destination of the goods taken out from the frontage by lighting the indicator provided in order to identify each container of the cart designated by instruction | indication information.

In the above-described embodiment, the example has been described in which the article take-out determination unit determines whether or not an article is taken out based on the weight loss value by the weighing unit. It is not limited. For example, when sensors (for example, photo interrupters) are arranged above and below the opening of the container 31 and the upper sensor detects an obstacle and the lower sensor detects an obstacle, the operator b places his hand in the container. If the detection of the lower sensor continues to disappear and the detection of the upper sensor disappears, the operator b determines that the hand has been taken out of the container, thereby determining whether or not the article has been removed. Good. In addition, for example, a camera that captures the inside of the container 31 may be installed in the cart 30, and whether or not an article is taken out may be determined based on a change in the captured image.
Moreover, in the said embodiment, although demonstrated in the example which provides a scale in each frontage of a cart and a sorting shelf, you may make it provide a scale only in the lower part in which the container of a cart is arrange | positioned.

  Further, in the above embodiment, every time an article is put into each frontage specified as the input destination (step S168 in FIG. 11), whether or not a predetermined number of articles are put into each frontage. A determination is made (step S143 in FIG. 10), and the confirmation button is lit for each frontage where the input is completed, and the operator confirms the completion of the input (steps S170 and S171 in FIG. 11). When it is confirmed that all of the specified frontage has been charged (step S170 and step S172 in FIG. 11: Yes), the weight reduction value of the article in the cart container and the whole frontage specified as the destination of the article In the above example, it is determined whether or not the weight increase values match (step S147 in FIG. 10). However, a certain article is thrown into each frontage identified as a loading destination. A, and the reduced weight value of the article in the basket, it may be determined whether the increased weight values match the submission destination of the frontage of the article.

  Further, in the above embodiment, every time an article is put into each frontage specified as the input destination (step S168 in FIG. 11), whether or not a predetermined number of articles are put into each frontage. Judgment is made (step S143 in FIG. 10), and when the predetermined number of inputs has not been completed for any frontage, it waits for the article to be taken out again from the cart container (step S136 in FIG. 10). However, within a predetermined time after an article is taken out from the cart container (within a predetermined time after the weighing value of the weighing means related to the article in the cart decreases), the article However, if it is not inserted into any slot specified as the loading destination (if the measured value of the measuring means at any of the above-mentioned slots does not increase), the notification information (for example, the article is Predetermined That has not been put into the mouth) may be controlled so as to be displayed on the display unit of the cart. Further, when all the articles taken out from the cart at a time are not put into any of the above-mentioned frontage within the predetermined time (the measured value of the weighing means related to the article in the cart is reduced, any of the above If the measurement value of the measuring means at the front end does not increase), the notification information may be controlled to be displayed on the display unit of the cart. The predetermined time may be a time according to the weight of the article. For example, a heavy article may take a long time.

  Further, in the sorting management information file of FIG. 7A in the above embodiment, information indicating the end of the work is stored for each article identification information and for each frontage number, so that an input operation of a certain article is performed within a predetermined time. For the frontage that has not been completed, the product name and frontage number may be displayed on the display unit of the cart as a frontage for which the product has not been loaded. The predetermined time may be a time according to any one or more of the weight of the article, the position of the frontage, and the number of inputs for each frontage by product. For example, a heavy article may take a long time, a frontage belonging to a location far from the temporary article placement table in FIG.
