Description

  The present invention belongs to the technical field of article sorting performed at a distribution site such as a warehouse or a distribution center.

  In general, in the logistics process from the manufacture and production of a wide variety of industrial products and processed foods to the hands of consumers, sorting operations are performed to collect a plurality of different items for each shipping destination. . Conventionally, a picking operation known as one of the sorting operations is a method in which an operator picks up items to be collected according to sorting information from a shelf in which a plurality of items are stored for each item, and collects the items for each destination. It will be put into the product container. Also, a well-known sorting operation as one of the sorting operations is to put the articles to be collected into the collection containers installed on the shelves for each shipping destination according to the sorting information by the number to be collected. It is.

  For example, as disclosed in Patent Literature 1 and Patent Literature 2, there is known a sorting system using a computer that assists in performing sorting work accurately and easily in a short time. In this case, an instruction lamp for notifying the operator of the article to be picked or the collection container to be sorted, the number display window for notifying the picking quantity or the sorting quantity, and the completion or collection of the article are displayed. A completion button or the like is provided for an operator to notify completion of sorting work upon completion of charging into the product container.

  More specifically, the sorting operation of the sorting system as described above is performed as follows. The sorting position that is the target of this sorting work at each of multiple sorting positions (the storage position of the goods for each item in the case of picking work, the installation position of the collection container for each shipping destination in the case of sorting work) And the number display window for displaying the number of sorting when the instruction lamp is instructed to be a sorting position to be sorted by the instruction lamp, The completion button for notifying completion of the sorting operation when the instruction lamp indicates that the sorting position is the target of the sorting operation is provided. At the start of the sorting operation, the instruction lamps provided at all the sorting positions to be sorted are turned on all at once and the number of sorting is displayed all at once in the number display window. The operator picks the articles at the sorting position where the instruction lamp is lit by the sorting number displayed in the number display window, or puts the articles at the sorting position where the instruction lamp is lit. After sorting according to the number of sorts displayed on the screen, the completion button is pressed.

  In this case, there is no problem when there is only one sorting position that is the target of sorting work from the beginning, but there are usually multiple sorting positions that are the target of sorting work, and therefore the indicator lamps are simultaneously at multiple sorting positions. In addition, the number of sorts is displayed at the same time in the number display window at multiple sorting positions.For example, the operator sorts the sorting numbers between adjacent sorting positions, or mistakes the completion button. The problem of pressing occurs.

  As a technique for dealing with this problem, in the sorting systems disclosed in Patent Document 1 and Patent Document 2, the indicator lamps provided at all sorting positions to be sorted are turned on all at once, but the number display window Discloses that the number of sorting is not displayed all at once, but only the number of sorting at the sorting position selected by the operator with the selection button is displayed in the number display window. As a result, since only the number of sorting at one sorting position is always displayed during sorting work, even if there are multiple sorting positions to be sorted, the operator can set the sorting number and completion button between the sorting positions. In addition to avoiding mistakes, the operator selects the sorting position by his / her own intention, so that the waste of operation is eliminated and the sorting operation can be performed rationally.

Japanese Patent Publication No. 6-20930 Japanese Utility Model Publication No. 63-16647

  However, in the sorting system disclosed in Patent Document 1, the indicator lamp, the number display window, or the completion button as described above are not on the side where the article is stored or the collection container is installed, but on the worker side. Since the sorting information is not displayed on the side of the shelf where the sorting position is located in the first place, the operator compares the display of the moving vehicle with the sorting position of the shelf and associates them. There is a problem that the work burden increases and mistakes are likely to occur.

  In this regard, in the sorting system disclosed in Patent Document 2, the indicator lamp, the number display window, the completion button, and the like as described above are provided on the side of the shelf where the articles are stored or the collection container is installed. Therefore, the trouble like the sorting system disclosed in Patent Document 1 is avoided. However, in that case, the indicator lamp and the completion button are integrated and provided at each of a plurality of sorting positions, but a number display window for displaying the number of picking or sorting is originally provided at a plurality of sorting positions. Because it is not provided for each, and only one common is provided for a plurality of sorting positions, the worker must look away from the shelf and look at the number display window at the time of sorting work, Again, there is a problem that the work load increases and errors are likely to occur.

  Therefore, the present invention provides a sorting system capable of suppressing the problem that the operator mistakes the sorting number between the sorting positions or the pressing of the completion button wrongly while avoiding an increase in work load. Let it be an issue.

  In order to solve the above problems, the invention according to claim 1 of the present application is directed to each of a plurality of sorting positions, a work target instruction means for instructing that the sorting position is a sorting work target, and the sorting work. The sorting system is provided with a number display means for displaying the number of sorting and a completion notifying means for notifying completion of the sorting work, and becomes a target of sorting work at the start of the sorting work. Control means for operating the work target instruction means provided at all the sorting positions, and a sorting position provided at each of a plurality of sorting positions and at which the work target instruction means is operated by the control means. Selection means for selecting one sorting position, and the control means includes the number display means provided at the sorting position selected by the selection means. Characterized in that it is configured to movement.

  Next, the invention described in claim 2 displays, on each of a plurality of sorting positions, a work target instruction means for instructing that the sorting position is a sorting position to be sorted, and a sorting number of the sorting works. A sorting system provided with a number display means for completion and a completion notification means for notifying completion of the sorting work, provided at all sorting positions to be sorted at the start of the sorting work Control means for operating at least one of the work object instruction means or the number display means, and at least one of the work object instruction means or the number display means provided in each of a plurality of sorting positions. Selection means for selecting one of the sorting positions activated, and the control means is selected by the selection means. Characterized in that it is configured to operate at different operating conditions and operating states of at least one other sorting position of the work subject indication means or the number display unit is provided on the sorting position has.

  Next, the invention described in claim 3 displays a work object instruction means for instructing that each of the plurality of sorting positions is a sorting position to be sorted, and a sorting number of the sorting works. A sorting system provided with a number display means for completion and a completion notification means for notifying completion of the sorting work, and at the start of the sorting work, of all sorting positions to be sorted A control means for operating the work object indicating means provided at one sorting position, and a sorting position provided at each of a plurality of sorting positions and operating the work object indicating means by the control means. And the control means operates the number display means provided at the sorting position selected by the selection means, and the number When completion of the sorting operation is notified by the completion notifying means provided at the sorting position where the indicating means is operated, it is provided at one of the remaining sorting positions to be sorted. The work object instruction means is configured to operate.

  According to a fourth aspect of the present invention, in the sorting system according to any one of the first to third aspects, the selection unit is configured using the completion notification unit.

  First, according to the invention described in claims 1 to 4, the sorting system has a configuration in which the work target instruction unit, the number display unit, and the completion notification unit are provided in each of a plurality of sorting positions. Sorting information will be displayed in the vicinity of each sorting position. As a result, for example, the operator must compare the display of the moving vehicle and the sorting position of the shelf and associate them with each other. There is an advantage that the trouble of having to keep an eye on the shelf from time to time to see the number display window is avoided, the burden on the operator's sorting work is reduced, and errors are reduced.

  In addition, according to the first aspect of the present invention, only the number display means provided at one sorting position selected by the operator displays the sorting number. The sorting number is displayed only at one sorting position in the selected sorting work, and one sorting position in the sorting work selected by the operator and another sorting position before the sorting work not selected by the worker As a result, even if there are multiple sorting positions to be sorted, the operator can set the sorting number between the sorting positions. It is possible to avoid the problem of sorting by mistake or pressing the completion button by mistake.

  Next, according to the invention described in claim 2, at least one of the work object indicating means or the number display means provided at one sorting position selected by the operator is operated differently from the operating state at the other sorting position. Since it operates in a state, during the sorting operation, one sorting position during the sorting operation selected by the operator and another sorting position before the sorting operation not selected by the worker are visually clear. As a result, even if there are multiple sorting positions to be sorted, it is possible to avoid the problem that the worker sorts the sorting numbers between sorting positions or presses the completion button incorrectly. .

  Next, according to the invention described in claim 3, the operator selects (acknowledges) one sorting position automatically selected by the sorting system, and only the number display means provided at the sorting position sorts. Since the number is displayed, during the sorting operation, the sorting number is displayed only at one sorting position in the sorting operation automatically selected by the sorting system and confirmed by the worker, and the sorting operation is confirmed by the worker. One sorting position can be clearly distinguished visually from the other sorting positions before the sorting work that the operator has not confirmed, and only one piece is displayed. Even if there are multiple sorting positions that are the targets of work, it is possible to avoid the problem that the worker sorts by sorting the sorting numbers between sorting positions or presses the completion button incorrectly. .

  According to the invention described in claim 4, the selection means for the operator to select or confirm the sorting position and the completion notification means for the operator to notify the completion of the sorting work are also used. Therefore, an increase in the number of parts and cost of the sorting system can be avoided. Hereinafter, the present invention will be described in more detail through the best mode of the present invention.

  In the present embodiment, the present invention is applied to the sorting system shown in FIG. The sorting system 1 can be used for both picking work and sorting work. A plurality of shelves 2 (in the case of picking) for storing a plurality of articles for each item or a plurality of shelves 2 (in the case of sorting) for installing a plurality of collection containers for each shipping destination are arranged on the floor of the sorting workshop. It is installed at. The worker a passes between the shelves 2... 2 along the traveling direction indicated by the arrow c while traveling the carriage b. The two shelves 2 and 2 facing each other constitute one zone Z, and the worker a meanders the six zones Z... Z in an S shape in the illustrated example. Of course, the worker a may skip the shelf 2 that is not the target of the picking work.

  As shown in FIG. 2, the control system of the sorting system 1 has a control PC (personal computer) 3 that functions as a sorting controller at the top, and a console 4 and display controllers 5. Are connected by network in order. A display controller 5 is provided for each zone Z (see FIG. 1) and controls a plurality of lower displays 6... 6. The control PC 3 registers inventory data and receipt / shipment data of articles for each item, order data and delivery date data for each customer, etc., and sorting information for each shipping destination based on the registration data Information on how many items are collected) and the sorting information is sequentially transmitted to the console 4. Then, in response to a request from the display controller 5, the console 4 transmits sorting information that matches the request among the accumulated sorting information to the display controller 5.

  As shown in FIG. 3, the shelf 2 is provided with a plurality (21 in the illustrated example) of sorting positions X ... X, and each sorting position X has a display 6 and an article storage container 7 (in the case of picking) or a collection. A container 7 (in the case of sorting) is installed. The worker a loads a collection container d... D (for picking) or an article storage container d... D (for sorting) for each item on the cart b. The articles taken out from the cart b are put into the collection containers d... D of the carriage b (in the case of picking) or the articles taken out from the article storage containers d. Go (for sorting).

  As shown in FIG. 4, the display 6 includes an indication lamp 62, a number display window 63, a completion button 64, and a selection button 65 on the front surface of the display case 61. Here, the instruction lamp 62 instructs the operator a by lighting or blinking that the sorting position X at which the lamp is provided is the sorting position X that is the target of the current sorting work. The number display window 63 displays the number of sorting at the sorting position X, which is instructed by the instruction lamp 62 as the target of the current sorting work, to the worker a. Further, the completion button 64 indicates that the current sorting operation is instructed by the instruction lamp 62, and that the sorting operation at the sorting position X in which the number of sorting is displayed by the number display window 63 is completed. This is notified to the upper display controller 5 or the like by the pressing operation of the worker a. The selection button 65 is used when the operator a selects one sorting position X from one or a plurality of sorting positions X in which the instruction lamp 62 and the number display window 63 are operated, as will be described later. For example, a pressing operation is performed.

  As described above, the sorting system 1 has a configuration in which the instruction lamp 62, the number display window 63, and the completion button 64 are provided in each of the plurality of sorting positions X ... X. As a result, for example, the worker a must compare the display of the carriage b with the sorting position X of the shelf 2 and associate them with each other, or the worker a displays the number at the time of sorting work. There is an advantage that the trouble of having to keep an eye on the shelf 2 to see the window 63 is avoided, the burden of the sorting work of the worker a is reduced, and errors are reduced.

  In the sorting work, as shown in FIG. 1, the worker a first enters the carriage b into the work using the console 4, and then proceeds to the entrance of each zone Z. Here, while the other worker a and the carriage b are in the zone Z, they wait at the entrance. The operator a inputs an identification code or the like of the carriage b by using a bar code or an ID tag at the entrance of the zone Z, thereby indicating which carriage b has arrived at the entrance of which zone Z. 5 is notified. The display controller 5 receives the notification of the arrival of the carriage b and requests the console 4 to transmit sorting information for the carriage b. Alternatively, the display controller 5 may receive and accumulate the sorting information for the carriage b from the console 4 in advance when the worker a enters the work using the console 4. In any case, the display controller 5 controls the operation of the displays 6... 6 and the zone lamp 7 based on the sorting information transmitted from the console 4. Hereinafter, the sorting operation will be described in more detail with reference to the flowchart shown in FIG. Note that steps S1, S7, and S12 represented by broken lines in the flowchart of FIG. 5 indicate that the operation is not an operation performed by the sorting system 1 but an operation performed manually by the worker a. .

  First, in step S1, the worker a inputs picking instruction data or sorting instruction data (sorting information: the same applies hereinafter) to the control PC 3. Next, in step S <b> 2, the control PC 3 transmits the instruction data to the console 4. Next, in step S <b> 3, the console 4 transmits the instruction data to the display controller 5.

  Next, in step S4, the sorting system 1 determines whether or not there is an instruction on the adjacent displays 6. As a result, if there is, the display controller 5 transmits a lamp blinking command to all the displays 6... Next, in step S6, the indicators 6... 6 that have received the lamp blink command blink the indicator lamps 62.

  Next, in step S7, the operator a presses the selection button 65 of any one of the displays 6... 6 in which the instruction lamp 62 is blinking. Next, in step S8, the display 6 whose selection button 65 has been pressed transmits that fact to the display controller 5. Next, in step S9, the display controller 5 transmits the number of instructions (the number of sorting: the same applies hereinafter) only to the display 6 for which the selection button 65 has been pressed.

  On the other hand, if there is no instruction to the adjacent displays 6... 6 in step S4, the display controller 5 transmits the number of instructions to all the displays 6.

  In any case, the one or more indicators 6 or 6... 6 that have received the instruction number display the instruction number on the number display window 63 in step S11.

  Next, in step S12, the worker a performs picking or sorting by looking at the number of instructions on the display 6, and presses the completion button 64. Next, in step S13, the display 6 in which the completion button 64 has been pressed turns off the display (both the instruction lamp 62 and the number display window 63), and transmits the completion record to the display controller 5.

  Next, in step S14, the sorting system 1 determines the presence / absence of the display 6 in which the number of instructions is displayed in the number display window 63 (this determination is meaningful when going from step S4 to step S10). If yes, the process returns to step S12. If not, in step S15, the sorting system 1 determines the presence or absence of the indicator 6 in which the indicator lamp 62 is blinking (this determination is made from step S4 to step S5). If it is present, the process returns to step S7. If not, the display controller 5 transmits the completion record to the console 4 in step S16.

  Next, in step S <b> 17, the console 4 transmits a completion record to the control PC 3. Next, in step S18, the sorting system 1 determines the presence / absence of the next instruction data. If there is no such instruction data, the sorting system 1 ends. If there is, the display controller 5 sends the next control data to the console 4 in step S19. After requesting the instruction data, the process returns to step S3.

  As described above, as shown in FIG. 6, in the display device 6 in which the selection button 65 is pressed in step S7, the number of sorting is displayed in the number display window 63 while the instruction lamp 62 is blinking in steps S9 and S11. It will be. That is, since only the number display window 63 of one sorting position X selected by the worker a displays the sorting number, during the sorting work, one sorting position X in the sorting work selected by the worker a is displayed. The sorting number is displayed only, and one sorting position X during sorting work selected by the worker a and the other sorting positions X... X before the sorting work not selected by the worker a are visually displayed. Since it is possible to clearly distinguish and only one number is displayed, as a result, even if there are a plurality of sorting positions X... X that are targets of sorting work, the operator a is between the sorting positions X and X. It is possible to avoid the problem of sorting with the number of sorting wrong or pressing the completion buttons 64, 64 with the wrong button.

  The above example is the embodiment of the invention described in claim 1. However, as an embodiment of the invention described in claim 2, for example, as shown in FIG. When the selection button 65 of the display device 6 on which the sorting number is displayed on the window 63 is pressed, the indication lamp 62 may be changed to a blinking state while the sorting number display on the number display window 63 remains unchanged. Alternatively, as shown in FIG. 8, when the selection button 65 of the display 6 in which the sorting number is displayed in the number display window 63 is pressed, the sorting number display in the number display window 63 changes to a blinking state. Good.

  That is, since at least one of the indication lamp 62 or the number display window 63 at one sorting position X selected by the worker a is different from the operating state at the other sorting position X, the worker a One sorting position X during the selected sorting operation can be clearly distinguished visually from the other sorting positions X... X before the sorting operation not selected by the operator a. Even if there are a plurality of target sorting positions X... X, it is possible to avoid the problem that the operator a sorts the sorting positions X and X with the wrong sorting number or presses the completion buttons 64 and 64 with each other.

  Furthermore, as an embodiment of the invention described in claim 2, as in the above example, in addition to the combination of turning off, blinking, and turning on the indicator lamp 62 and the number display window 63, the brightness of blinking or lighting is changed, By changing the blinking cycle or changing the color of blinking or lighting, it may be possible to distinguish between during the sorting operation and before the sorting operation.

  Furthermore, as another example of distinguishing between sorting work and before sorting work, characters and symbols indicating that work is in progress are used by using empty digit portions and empty segments of the number display window 63, While the number is displayed in the number display window 63, it may be displayed simultaneously while the selection button 65 is pressed. Alternatively, a working lamp indicating that the work is in progress is provided on the display 6 so that the working lamp is turned off before the work is performed, and the working lamp is turned on while the selection button 65 is pressed. Also good.

  Next, as an embodiment of the invention described in claim 3, only the indicator lamp 62 for one sorting position X automatically selected by the sorting system 1 is lit, and the operator a presses the selection button 65 for the sorting position X. It is also possible to select (acknowledge) later by pressing, and only the number display window 63 at the sorting position X may display the sorting number. In other words, during the sorting work, the sorting number is displayed only at one sorting position X in the sorting work that is automatically selected by the sorting system 1 and confirmed by the worker a. Since the sorting position X and other sorting positions X ... X before the sorting work that the operator a has not confirmed can be visually and clearly distinguished, and only one number is displayed, as a result, Even if there are a plurality of sorting positions X... X that are targets of sorting work, there is a problem that the operator a sorts by sorting the sorting numbers between the sorting positions X and X, or presses the completion buttons 64 and 64 incorrectly. Can be avoided.

  Here, in the flowchart of FIG. 5, the display controller 5 controls the operation of the indicator lamp 62 and the number display window 63 of the indicator 6, but instead the indicator 6 itself is instructed by the indicator lamp. 62 and the operation of the number display window 63 may be controlled. The sorting operation in that case will be described with reference to the flowchart shown in FIG. In the flowchart of FIG. 9, steps S21, S27, and S30 are represented by broken lines to indicate that the operation is not an operation performed by the sorting system 1 but an operation performed manually by the worker a. .

  First, in step S21, the worker a inputs picking instruction data or sorting instruction data (sorting information: the same applies below) to the control PC 3. Next, in step S <b> 22, the control PC 3 transmits the instruction data to the console 4. Next, in step S <b> 23, the console 4 transmits the instruction data to the display controller 5.

  Next, in step S24, the display controller 5 transmits the instruction data all at once to all the displays 6. Next, in step S25, the sorting system 1 determines whether or not there is an instruction on the adjacent displays 6. As a result, if there is, all the indicators 6... 6 that are instructed blink the indicator lamps 62.

  Next, in step S27, the operator a presses the selection button 65 of any one of the indicators 6 ... 6 in which the instruction lamp 62 is blinking. Next, in step S28, the display 6 on which the selection button 65 has been pressed displays the number of instructions (the number of sorting: hereinafter the same) in the number display window 63.

  On the other hand, if there is no instruction on the adjacent displays 6... 6 in step S 25, all the displays 6... 6 that are instructed simultaneously display the number of instructions on the number display window 63 in step S 29.

  Next, in step S30, the operator a performs picking or sorting by looking at the number of instructions on the display 6, and presses the completion button 64. Next, in step S31, the display 6 whose completion button 64 has been pressed turns off the display (both the instruction lamp 62 and the number display window 63), and transmits the completion record to the display controller 5.

  Next, in step S32, the sorting system 1 determines the presence / absence of the display device 6 in which the number of instructions is displayed in the number display window 63 (this determination is meaningful when going from step S25 to step S29). If yes, the process returns to step S30. If not, the sort system 1 determines whether or not the indicator 6 has the indicator lamp 62 blinking in step S33 (this determination is made from step S25 to step S26 to step S26). If it is present, the process returns to step S27. If not, the display controller 5 transmits a completion record to the console 4 in step S34.

  Next, in step S35, the console 4 transmits a completion record to the control PC 3. Next, in step S36, the sorting system 1 determines the presence / absence of the next instruction data. If there is no such instruction data, the sorting system 1 ends. If there is, the display controller 5 sends the next data to the console 4 in step S37. After requesting the instruction data, the process returns to step S23.

  In the above embodiment, as shown in FIG. 4, the indicator 6 includes the indication lamp 62, the number display window 63, the completion button 64, and the selection button 65 separately. As an embodiment of the invention described in FIG. 4, as illustrated in FIG. 10, a single selection / completion button 66 may be used as a completion button and a selection button. By integrating several buttons in this way, an increase in the number of parts or cost of the sorting system 1 can be avoided.

  Although the embodiment described above is the best embodiment of the present invention, it goes without saying that various modifications and improvements can be made without departing from the scope of the claims.

  As described above in detail with reference to specific examples, according to the present invention, while avoiding an increase in the burden of the worker's sorting work, the worker can sort the wrong number of sorting between the sorting positions, or the completion button. There is provided a sorting system capable of suppressing the problem of pressing the wrong button. The present invention has wide industrial applicability in the technical field of sorting systems such as picking systems and sorting systems.
